                                CREDIT AGREEMENT

         This Credit Agreement dated as of June 14, 2002, is entered into by and
among Willbros Group, Inc., a Republic of Panama corporation (herein referred to
as either "WGI" or the "Company"); the Designated Subsidiaries (as defined
herein) from time to time (WGI and such Designated Subsidiaries collectively,
the "Obligors" and individually, an "Obligor"); the several financial
institutions from time to time parties to this Agreement (collectively, the
"Banks" and individually, a "Bank"); Credit Lyonnais New York Branch, as a Bank,
as Issuing Bank (as defined herein), as administrative agent for the Banks (in
such capacity, the "Agent"), and as Lead Arranger and Joint Book Runner; CIBC
World Markets Corp., as Joint Lead Arranger and Joint Book Runner, and Canadian
Imperial Bank of Commerce, as Syndication Agent.

         The Banks have agreed to make available to the Borrowers (as defined
herein) a revolving credit facility for loans and letters of credit upon the
terms and conditions set forth in this Agreement and the other Credit Documents
(as defined herein).

         NOW, THEREFORE, in consideration of the mutual agreements, provisions
and covenants contained in this Agreement, the parties hereto (the "Parties")
hereby agree as follows:

                                    ARTICLE I
                                   DEFINITIONS

         1.1      Defined Terms. In addition to the terms defined elsewhere in
this Agreement, the following terms as used in the Credit Documents shall have
the following meanings:

         "Acceptable Bank Account" means a Bank Account that (i) is maintained
by a depositary bank which is a Bank or which has the qualifications set forth
in the definition of "Eligible Assignee" (or, if not maintained by a Bank or
other depositary bank having such qualifications, such Bank Account is a deposit
account and the balances in such Bank Account would at no time exceed U.S.
$100,000 or the Dollar Equivalent thereof) and (ii) is subject to an Acceptable
Security Interest.

         "Acceptable Credit Support" means a standby letter of credit payable in
an OECD Currency for the benefit of an Obligor to guarantee payment of a
Receivable due to such Obligor, which letter of credit is issued or confirmed by
a Bank or other issuing bank in an OECD country with a credit rating of at least
"A-" and for which an Acceptable Security Interest exists on all letter of
credit rights associated with such letter of credit.

         "Acceptable Security Interest" in any property means:

         (a) in the case of property other than Excepted Collateral (as defined
below), a Lien which (i) exists in favor of the Agent for the benefit of the
Secured Parties; (ii) is a first priority Lien superior to all other Liens
(other than Permitted Liens); (iii) secures the Secured Obligations; (iv) is
perfected and enforceable against all Persons in preference to
<PAGE>
any rights (other than Permitted Liens) of any Person therein; and (v) is in
full force and effect; and

         (b) in the case of property that is Excepted Collateral, a Lien created
pursuant to the Security Documents under the laws of the State of New York,
which Lien (i) exists in favor of the Agent for the benefit of the Secured
Parties; (ii) secures the Secured Obligations; (iii) is in full force and
effect; and (iv) is perfected pursuant to the Uniform Commercial Codes of the
State of New York and of the District of Columbia by a financing statement which
has been filed in the District of Columbia.

For purposes of this definition, "Excepted Collateral" means, as determined by
the Agent in its reasonable discretion, Collateral (i) for which a Lien cannot
be timely "perfected" under applicable law other than by filing a financing
statement in the District of Columbia or (ii) for which the costs of perfecting
a Lien under applicable law are disproportionately high compared to the value of
such Collateral for purposes of this Agreement, or (iii) otherwise specifically
designated as Excepted Collateral by the Agent for whatever reason.

         "Account Bank" means any bank or financial institution that maintains a
Bank Account.

         "Account Control Agreement" means any agreement executed by an Account
Bank in the form of Exhibit H or otherwise in form and substance satisfactory to
the Agent pursuant to which such Account Bank acknowledges the Lien of the Agent
over the Bank Accounts or lockbox arrangements of the Obligors maintained with
or by such Account Bank and agree to the Agent's control thereof for purposes of
creating an Acceptable Security Interest in such Bank Accounts or lockbox
arrangements.

         "Adjusted EBITDA" means, as of any date of determination, the sum of
earnings before interest, taxes, depreciation and amortization, calculated in
accordance with GAAP as of the end of the preceding fiscal quarter of the
Company for the trailing three fiscal quarters of the Company, net of foreign
cash taxes paid, and annualized. Non-cash charges (other than charges for
depreciation and amortization) shall be excluded in determining Adjusted EBITDA.

         "Affiliate" means, as to any Person, any other Person which, directly
or indirectly, is in control of, is controlled by, or is under common control
with, such Person. A Person shall be deemed to control another Person if the
controlling Person possesses, directly or indirectly, the power to direct or
cause the direction of the management or policies of the other Person, whether
through the ownership of voting securities, by contract or otherwise. Any
director, executive officer or beneficial owner of five percent (5%) or more of
the equity of a Person shall, for the purposes of this Agreement, be deemed to
control the other Person. Notwithstanding the foregoing, under no circumstances
shall the Agent or any Bank be deemed to be an Affiliate of any of the Obligors
or any Subsidiary of the Company.

                                       2
<PAGE>
         "Agent" means CLNY in its capacity as administrative agent for the
Banks under the Credit Documents, and any successor agent.

         "Aggregate Exposure" means the sum of (i) the principal amount of
outstanding Loans plus (ii) the aggregate outstanding Letter of Credit
Obligations; provided that for purposes of determining Aggregate Exposure on any
date that Letters of Credit denominated in any Alternative Currency are
outstanding, the provisions of Section 3.2(d) shall apply and the Aggregate
Exposure attributable to such Letters of Credit shall be the Dollar Equivalent
of such exposure in the applicable Alternative Currency.

         "Agreement" means this Credit Agreement, as it may be amended from time
to time in accordance with its terms.

         "Alternative Currency" means any currency other than Dollars which is
freely transferable into Dollars and otherwise acceptable to the Issuing Bank.

         "Applicable Margin" means, with respect to interest and fees described
in the Pricing Schedule (i) on any day when no Event of Default has occurred and
is continuing, the per annum percentage, expressed in basis points, set forth
for such interest and fees in the Pricing Schedule determined by the Ratio of
Consolidated Debt to Adjusted EBITDA on such date, and (ii) on any day when an
Event of Default has occurred and is continuing, the "Applicable Margin"
determined pursuant to clause (i) above from the Pricing Schedule for the
applicable interest or fees, plus two hundred (200) basis points per annum. The
Applicable Margin shall be adjusted on the date required by Section 8.1 for the
delivery of each of the Company's financial statements.

         "Asset Sale" means the sale, lease, transfer or other disposition for
value of any Collateral, whether voluntary or involuntary, by the Company or any

         2.1      Loans.

                  (a)      Each Bank severally agrees, on the terms and subject
to the conditions set forth in this Agreement, to make Revolving Loans to any
Borrower from time to time, on any Business Day during the period from the
Closing Date to the Maturity Date, in an aggregate amount for all Borrowers not
to exceed at any time outstanding an amount equal to (i) such Bank's Commitment
less (ii) such Bank's

                                       33
<PAGE>
Percentage Share of an amount equal to sum of the Letter of Credit Obligations
plus the Swingline Loans outstanding at such time; provided, that, after giving
effect to any requested Borrowing on such date and any issuance of Letters of
Credit on such date, (A) the Aggregate Exposure shall not exceed the Total
Commitment on such date, (B) Borrowing Base Exposure shall not exceed the Net
Borrowing Base on such date, and (C) the aggregate principal amount of all Loans
outstanding on such date shall not exceed the Loan Limit. Within the foregoing
limits, the Borrowers may borrow Revolving Loans under this Section 2.1(a),
prepay Revolving Loans pursuant to Section 2.5 and reborrow Revolving Loans
pursuant to this Section 2.1(a).

                  (b)      On the terms and conditions set forth in this
Agreement, the Swingline Bank may, in its sole discretion on any Business Day
during the period from the date of this Agreement until the Maturity Date, make
Swingline Loans to the Company from time to time in an aggregate principal
amount not to exceed $2,000,000 outstanding at any time; provided, that, after
giving effect to any requested Borrowing on such date and any issuance of
Letters of Credit on such date, (A) the Aggregate Exposure shall not exceed the
Total Commitment on such date, (B) Borrowing Base Exposure shall not exceed the
Net Borrowing Base on such date, and (C) the aggregate principal amount of all
Loans outstanding on such date shall not exceed the Loan Limit; and provided
further than no Swingline Loan shall be made by the Swingline Bank if the
Swingline Bank (x) has received a Swingline Restriction Notice and has not
received a Termination of Swingline Restriction Notice canceling such Swingline
Restriction Notice or (y) has actual knowledge that the statements set forth in
Section 7.2(b) and (c) are not true on the date of such Swingline Loan, it being
agreed by the Company that any request for a Swingline Loan by the Company and
the acceptance by the Company of the proceeds of such Swingline Loan shall
constitute a representation and warranty by the Company that on the date of such
Swingline Loan such statements are true. Within the foregoing limits, the
Company may borrow Swingline Loans under this Section 2.1(b), prepay Swingline
Loans pursuant to Section 2.5 and reborrow Swingline Loans pursuant to this
Section 2.1(b).

                  (c)      The Borrowers and the Banks agree that in the event
any Swingline Loan is not repaid on the date due to the Swingline Bank, the
Swingline Bank shall so notify the Agent and the Agent shall promptly notify
each of the Banks, and thereupon each Bank shall pay to the Agent for the
account of the Swingline Bank its Percentage Share of such Swingline Loan, it
being agreed that such Bank's obligation to pay its share of such Swingline Loan
shall be irrevocable notwithstanding the fact that such Swingline Loan matures
and becomes due and payable after the termination of the Commitments,
acceleration of the Loans, or otherwise, and whether or not the conditions
precedent in Section 7.2 have been satisfied (a "Mandatory Funding"). Unless an
Event of Default exists pursuant to Section 10.1(f) or (g), each such payment by
a Bank as part of a Mandatory Funding shall be deemed to be a Base Rate Loan
made to the Company pursuant to such Bank's Commitment as part of a Revolving
Borrowing of Base Rate Loans to the Company, and the Company hereby irrevocably
instructs the Swingline Bank to apply the proceeds of such Mandatory Funding to
the payment of the outstanding Swingline Loans. If an Event of Default does
exist pursuant to Section 10.1(f) or (g) at the time of any Mandatory Funding,
each payment by a Bank as part of such Mandatory

                                       34
<PAGE>
Funding shall be deemed to be such Bank's purchase of a participation interest
in the outstanding Swingline Loans. The Agent shall give each Bank notice of
such Mandatory Funding by 11:00 a.m. on the date the Mandatory Funding is to be
made. Each Bank shall make its portion of the Mandatory Funding available to the
Agent for the account of the Swingline Bank in immediately available funds by
1:00 p.m. on the date requested.

         2.2      Loan Accounts and Notes.

         (a)      Each Bank, with respect to amounts payable to it under the
Credit Documents, and the Agent, with respect to all amounts payable under the
Credit Documents, shall maintain on its books in accordance with its usual
practice, loan accounts and control accounts, respectively, setting forth each
Loan, the applicable interest rate and the amounts of principal, interest and
other sums paid and payable from time to time under the Credit Documents with
respect thereto; provided, however, that the failure, error or omission by a
Bank or the Agent to maintain an account or ledger or to record any information
therein shall not diminish or otherwise affect any of the Obligations of the
Borrowers under any Credit Document. In the case of any dispute, action or
proceeding relating to any amount payable under any Credit Document, the entries
in each such account shall constitute conclusive evidence of the accuracy of the
information so recorded in the absence of manifest error. In case of a
discrepancy between the entries in the Agent's books and any Bank's books, such
Bank's books shall be considered correct in the absence of manifest error.

                  (b)      In the event any Bank shall so elect by notice to the
Company and the Agent, each Borrower shall execute and deliver to such Bank a
Revolving Note to evidence the Revolving Loans of such Bank to such Borrower,
payable to the order of such Bank in a principal amount equal to the Commitment
of such Bank and otherwise duly completed. Each Bank holding such a Revolving
Note is hereby authorized by the respective Borrower executing such Revolving
Note to endorse on the schedule (or a continuation thereof) attached to such
Revolving Note, to the extent applicable, the date, amount and Type of each
Revolving Loan made by such Bank to such Borrower, and each continuation
thereof, each conversion of all or a portion thereof to another Type, the date
and amount of each payment or prepayment of principal thereof received by such
Bank and, in the case of Eurodollar Rate Loans, the length of each Interest
Period; provided, that any failure by any Bank to make any such endorsement
shall not affect the obligations of the Borrower under such Revolving Note or
this Agreement in respect of such Revolving Loan.

                  (c)      The Company shall execute and deliver to the
Swingline Bank the Swingline Note to evidence the Swingline Loans to the
Company, payable to the order of the Swingline Bank in a principal amount equal
to $2,000,000.

         2.3      Procedure for Borrowing.

                  (a)      Each Revolving Borrowing shall be made upon the
written notice of the Company acting on behalf of any Borrower in the form of a

                           (D)      the duration of the Interest Period
                  applicable to such Revolving Loans included in such notice,

                  (e)      The Company may request a Swingline Loan to be made

and the obligation of the applicable Borrower to repay such Loan shall
nevertheless be to such Bank and shall be deemed to be held by such Bank, to the
extent of such Loan, for the account of such branch or Affiliate.

                  (b)      Notwithstanding any provision of this Agreement to
the contrary, each Bank shall be entitled to fund and maintain its funding of
all or any part of its Loans in any manner it sees fit.

                                   ARTICLE III
                                LETTERS OF CREDIT

         3.1      Issuance of Letters of Credit.

                  (a)      From time to time, on any Business Day during the
period from the Closing Date to the date 15 Business Days prior to the Maturity
Date, on the terms and subject to the conditions set forth in this Agreement,
the Company may, on behalf of any Borrower, request the Issuing Bank to issue,
and each Bank to participate in, Standby LCs and Commercial LCs for the account
of such Borrower; provided, however, that: (i) the Issuing Bank shall not be
obligated to issue any Letter of Credit, nor shall any Bank be obligated to
participate in the same, if, after giving effect to such issuance, (x) the
Aggregate Exposure would exceed the Total Commitment or (y) Borrowing Base
Exposure would exceed the Net Borrowing Base; and (ii) the application for any
requested Letter of Credit, and any customary instruments and agreements
relating thereto must be satisfactory in form and substance to the Issuing Bank.
Any Letter of Credit shall be denominated in Dollars or an Alternative Currency.

                  (b)      Concurrently with the issuance of each Letter of
Credit by the Issuing Bank, each Bank shall be deemed to have purchased, and
hereby agrees to purchase, irrevocably and unconditionally, from the Issuing
Bank, without recourse, an undivided interest and participation in the related
Letter of Credit Obligation in an amount equal to the product of (i) its
Percentage Share and (ii) the Letter of Credit Obligation related to such Letter
of Credit (or, if applicable, the Dollar Equivalent thereof).

                                       41
<PAGE>
                  (c)      Each issuance of a Letter of Credit shall be deemed
to utilize the Commitment of each Bank in an amount equal to such Bank's
Percentage Share of the Letter of Credit Obligations related to such Letter of
Credit (or, if applicable, the Dollar Equivalent thereof).

                  (d)      The Issuing Bank shall not be obligated to issue any
Letter of Credit under this Agreement if such issuance would conflict with, or
cause any Borrower, the Issuing Bank, or any Bank participating in a Letter of
Credit to be in violation of any Legal Requirement, including any prohibition of
the foreign assets control regulations of the United States Treasury Department,
or after the Issuing Bank or any Bank has promptly notified the Agent that it
cannot, for any reason, issue or participate in a Letter of Credit. If a Letter
of Credit will not be issued because of either of the reasons stated in the
preceding sentence and the failure to issue was not due to any Borrower's or any
Bank's violation of any Legal Requirement, the applicable Borrower may obtain
such letter of credit from a third party to the extent permitted by Section 9.4.

         3.2      Use of Letters of Credit.

                  (a)      A Standby LC shall be issued for the account of a
Borrower only for the following purposes: (i) to provide guarantees of certain
obligations of such Borrower such as bid, advance payment, retention release,
customs, warranty and performance guarantees, (ii) to provide counter guarantees
in support of bank guarantees issued for the account of such Borrower outside
the U. S. for the purposes set forth in Section 3.2(a)(i), (iii) to support
local currency borrowings of such Borrower outside the U. S., (iv) to support
judicial proceedings of such Borrower, (v) for any other purpose in the ordinary
course of business of such Borrower, and (vi) for any other purpose agreed to by
the Required Banks.

                  (b)      A Commercial LC shall be issued for the account of a
Borrower only in support of trade obligations incurred in the ordinary course of
business of such Borrower and must have a maximum term (subject to Section
3.2(c)) of one year.

                  (c)      No Letter of Credit shall have an expiration date
(including all rights of renewal) later than five (5) Business Days prior to the
Maturity Date.

                  (d)      For the purpose of ensuring compliance with the
borrowing limitations set forth herein, the Agent may (but shall not be
obligated to) at any time determine the equivalent in Dollars of the face amount
of each Letter of Credit denominated in an Alternative Currency by using the
quoted spot rate at which CLNY's office in New York, New York offers to sell
Dollars for such Alternative Currency in New York City at 2:00 p.m. on any such
determination date. If no such spot rate is quoted, the Agent may use a spot
quote determined by any other reasonable method.

         3.3      Issuance Procedures.

                  (a)      Each Letter of Credit shall be issued upon the
request of the Company on behalf of any Borrower, received by the Issuing Bank
(with a copy to the Agent) not later than 3:00 p.m. three Business Days prior to
the requested date of

                                       42
<PAGE>
issuance. Upon receipt of such request, the Issuing Bank will request the Agent
to determine that after giving effect to the issuance of the Letter of Credit so
requested, the Aggregate Exposure will not exceed the Total Commitment, and
Borrowing Base Exposure will not exceed the Net Borrowing Base, and the Agent
will promptly notify the Issuing Bank of such determination. The Agent will
promptly notify each Bank of each request for issuance of a Letter of Credit.

                  (b)      Each request for issuance of a Letter of Credit shall
be made in writing to the Agent and the Issuing Bank by telecopier and confirmed
by delivery (not more than one Business Day thereafter) of a Letter of Credit
Application and Agreement, in the case of a Standby LC, in the form of Exhibit
G-1, and, in the case of a Commercial LC, in the form of Exhibit G-2 (each, an
"LC Application"). Each request for issuance of a Letter of Credit shall
specify, among other things: (i) the proposed date of issuance (which shall be a
Business Day); (ii) the Person on whose behalf the Letter of Credit is to be
issued; (iii) the face amount of the Letter of Credit; (iv) the date of
expiration of the Letter of Credit; (v) the name and address of the beneficiary
thereof; (vi) the documents to be presented by the beneficiary of the Letter of
Credit in case of any drawing thereunder; (vii) the full text of any certificate
to be presented by the beneficiary in case of any drawing thereunder; (viii)
other proposed terms of such Letter of Credit; (ix) the nature of the
transaction proposed to be supported by such Letter of Credit; and (x) whether
such Letter of Credit is a Performance SBLC, a Financial SBLC or a Commercial
LC. The Company shall furnish such additional information regarding such
transaction as the Agent or the Issuing Bank may reasonably request in writing.

                  (c)      The Issuing Bank shall notify the Agent of each
issuance of a Letter of Credit on the date such Letter of Credit is issued and
on the date of such issuance inform the Agent by telecopier of the type, amount
and expiration date of such Letter of Credit. The Agent shall promptly notify
the Banks of each issuance of a Letter of Credit by the Issuing Bank.

                  (d)      Any request for an amendment to any previously issued
Letter of Credit shall (i) be received by the Agent and the Issuing Bank not
later than 3:00 p.m. two Business Days prior to the date of the proposed
amendment in writing by telecopier, (ii) shall be signed by the Company on
behalf of the Borrower for whose account such Letter of Credit was issued, and
(iii) if a request for an extension, request a new expiry date not later than
five (5) Business Days prior to the Maturity Date. The Issuing Bank shall notify
the Agent by telecopier of each amendment made to any Letter of Credit on the
date of such amendment, and the Agent shall notify the Banks thereof. The
Issuing Bank shall promptly notify the Company if for any reason the Issuing
Bank does not intend to execute the requested amendment on or before the date
specified in the Company's written request and shall specify the reasons
therefore.

                  (e)      Notwithstanding any provision of any LC Application
to the contrary, in the event of any conflict between the terms of any such LC
Application and the terms of this Agreement, the terms of this Agreement shall
control with respect to provisions relating to events of default,
representations and warranties, and covenants in the respective documents,
except that such LC Application may provide for further

                                       43
<PAGE>
warranties relating specifically to the transaction or affairs underlying such
Letter of Credit.

                  (f)      Each Commercial LC shall be subject to the UCP and,
to the extent not inconsistent therewith, the laws of the State of New York.
Each Standby LC shall be subject to the UCP or the ISP 98 and, to the extent not
inconsistent therewith, the laws of the State of New York.

         3.4      Drawings and Reimbursements.

                  (a)      If, in accordance with its standard operating
procedures, the Issuing Bank determines that a demand for payment under a Letter
of Credit conforms to the terms and conditions of such Letter of Credit, the
Issuing Bank shall, as soon as reasonably practicable, give notice to the
Company and the Agent of the date the Issuing Bank will make payment in
connection with such Letter of Credit in accordance with the terms thereof. The
Agent shall promptly notify the Banks of such date. Each Bank and each Borrower
acknowledges that the Issuing Bank shall have no greater responsibility in the
operation of the Letters of Credit than is specified in the UCP or the ISP 98,
as applicable. If at any time the Issuing Bank shall have made a payment to a
beneficiary of a Letter of Credit in respect of a drawing under such Letter of
Credit, the Issuing Bank shall promptly notify the Company and the Agent (and
the Agent shall thereafter notify each Bank).

                  (b)      Each Borrower unconditionally and irrevocably agrees
to pay to the Issuing Bank, on the date of any payment by the Issuing Bank of a
drawing under any Letter of Credit issued for the account of such Borrower, an
amount equal to the amount paid by the Issuing Bank in respect of such drawing
or, if applicable, the Dollar Equivalent of such amount (such payment obligation
of each Borrower herein called, a "Reimbursement Obligation"). If any
Reimbursement Obligation is not paid when due (whether directly, by means of a
Revolving Borrowing of Base Rate Loans as provided in Section 3.4(c), or by
application of any funds in the Cash Collateral Account), the respective
Borrower agrees to pay interest accrued on the principal amount thereof from the
date it became due until it is paid in full to the Issuing Bank at a rate per
annum equal to the Default Rate, such interest due and payable on demand. Each
such Reimbursement Obligation and the respective Borrower's obligation to pay
interest thereon as set forth herein is irrevocable and unconditional with
respect to any amount paid by the Issuing Bank under any Letter of Credit issued
for the account of such Borrower, without presentment, demand, protest or other
formalities of any kind, all of which are hereby expressly WAIVED by each
Borrower.

                  (c)      Subject to the terms and conditions of this
Agreement, each Borrower may satisfy its Reimbursement Obligation by causing the
Company to request a Revolving Borrowing of Base Rate Loans prior to 11:00a.m.
on the date due in accordance with Section 2.1(a), the proceeds of which Loans
will be used to pay such Reimbursement Obligation to the Issuing Bank.

                                       44
<PAGE>
                  (d)      If on any date a Reimbursement Obligation is due (i)
the Company shall fail to deliver a timely Notice of Revolving Borrowing
pursuant to Section 2.3(a) requesting Base Rate Loans in an amount sufficient to
pay such Reimbursement Obligation, or for any reason such a Revolving Borrowing
cannot be made, (ii) the respective Borrower shall fail to request the Agent to
apply funds contained in the Cash Collateral Account to pay such Reimbursement
Obligation, or there shall be insufficient funds available for payment thereof
in the Cash Collateral Account, and (iii) the respective Borrower shall
otherwise fail to pay a Reimbursement Obligation by 11:00 a.m. on the date such
Reimbursement Obligation is due, then the Issuing Bank shall promptly notify the
Agent and the Agent shall promptly notify the other Banks. Each Bank will pay to
the Agent for the account of the Issuing Bank an amount equal to such Bank's
Percentage Share of such unpaid Reimbursement Obligation (such payment by each
Bank to be made on the same date such Bank receives such notice, provided such
notice is received by 12:00 noon, and otherwise by 10:00 a.m. on the next
succeeding Business Day), together with interest on such amount for each day
from the date of such Bank's receipt of such notice from the Agent (or, if such
notice is received after 12:00 noon on such date, from the next succeeding
Business Day) to the date of payment by such Bank of such amount at a rate of
interest per annum equal to the Federal Funds Rate from time to time in effect
during such period.

                  (e)      Upon and only upon receipt by the Issuing Bank of
funds from, or on behalf of, a Borrower, (i) in respect of a Reimbursement
Obligation with respect to which any Bank has theretofore made a payment to the
Issuing Bank pursuant to Section 3.4 (c) or (d), or (ii) in payment of interest
thereon, the Issuing Bank will pay to each Bank through the Agent, in the same
funds as those received by the Issuing Bank, such Bank's pro rata share of such
funds.

                  (f)      If the Issuing Bank is required at any time to return
to a Borrower or to a trustee, receiver, liquidator, custodian or other similar
official any portion of the payments made by such Borrower to the Issuing Bank
in respect of a Reimbursement Obligation or interest thereon, each Bank shall,
on demand of the Agent, forthwith pay to the Issuing Bank its Percentage Share
of any amounts so returned by the Issuing Bank, plus interest thereon from the
date such demand is made to the date such amounts are paid by such Bank to the
Issuing Bank at a rate per annum equal to the Federal Funds Rate.

                  (g)      If any Borrower ever alleges gross negligence or
willful misconduct by the Issuing Bank or the Issuing Bank has honored a Letter
of Credit in violation of applicable law, the full amount of the Reimbursement
Obligation provided for in this Section 3.4 shall nonetheless be paid upon
demand, subject to later adjustment or reimbursement at such time, if any, as a
court of competent jurisdiction enters a final judgment as to the extent and
effect of any alleged gross negligence or willful misconduct. The Issuing Bank
will pay to the Agent for the account of each Bank such Bank's Percentage Share
of all amounts received from any Borrower for application in payment, in whole
or in part, of the Reimbursement Obligation in respect of any Letter of Credit,
but only to the extent such Bank has made payment to the Issuing Bank in respect
of such Letter of Credit.

         3.5      Cash Collateralization.

                  (a)      If, after giving effect to any mandatory prepayment
of Loans under Section 2.6(b), the Borrowing Base Exposure still exceeds the Net
Borrowing Base as reduced, then the Borrowers shall promptly thereafter deposit
funds into the Cash Collateral Account in the amount of such excess to secure
the outstanding Obligations.

                  (b)      If, after giving effect to any mandatory prepayment
of Loans under Section 2.6(c), the Aggregate Exposure still exceeds the Total
Commitment, then the Borrowers shall promptly thereafter deposit funds into the
Cash Collateral Account in the amount of such excess to secure the outstanding
Obligations.

                  (c)      On the date of any Asset Sale, if after giving effect
to the mandatory prepayment of Loans required pursuant to Section 2.6(d), the
Borrowing Base Exposure then outstanding would exceed the Net Borrowing Base
(adjusted by reducing the Net Borrowing Base by the value (if any) previously
given to the asset sold in the Net Borrowing Base and by adding to the Net
Borrowing Base the value of any Net Cash Proceeds from the sale eligible for
inclusion in the Net Borrowing Base), then the Borrowers shall promptly
thereafter deposit funds into the Cash Collateral Account in the amount of such
excess to secure the outstanding Obligations.

         3.6      Role of the Issuing Bank.

                  (a)      The Issuing Bank will exercise and give the same care
and attention to the Letters of Credit issued by it as it gives to other letters
of credit issued by it.

                  (b)      Each Bank agrees that, in paying any drawing under
any Letter of Credit, the Issuing Bank shall not have any responsibility to
obtain any document (other than any document expressly required by the terms of
such Letter of Credit) or to ascertain or inquire as to the validity or accuracy
of any document or the authority of the Person delivering any document. None of
the Issuing Bank or any of their representatives, officers, employees or agents
shall be liable to any Bank for: (i) any action taken or omitted in connection
herewith at the request or with the approval of the Required Banks; (ii) any
action taken or omitted in the absence of gross negligence or willful
misconduct; or (iii) any action taken or omitted affecting the execution,
effectiveness, genuineness, validity or enforceability of any Letter of Credit
or any other document contemplated hereby or thereby.

                  (c)      All Letters of Credit issued by the Issuing Bank
pursuant to this Agreement shall be evidenced by entries in records maintained
by the Issuing Bank, which records shall be conclusive evidence, absent manifest
error, of all of the Letter of Credit Obligations and the Reimbursement
Obligations. Failure by the Issuing Bank to record the issuance of any Letter of
Credit or any payment or reimbursement with respect thereto or any error in so
recording any such fact, shall not, however, limit or otherwise affect any of
the Letter of Credit Obligations or Reimbursement Obligations.

                                       46
<PAGE>
                  (d)      So long as the Issuing Bank shall have acted in good
faith, the Issuing Bank shall not be responsible to any Obligor for, and such
Bank's right to reimbursement, indemnification, and other payments under this
Agreement and the other Credit Documents shall not be impaired by, (i) any act
or omission for which banks are relieved of responsibility under the UCP, (ii)
any recommendation or failure to recommend the inclusion or exclusion of any
term or wording in a Letter of Credit, or (iii) honor or dishonor or refusal of
any demand under a Letter of Credit following any Obligor's refusal to confirm
that such demand is entitled to be honored or that such Bank is entitled to be
reimbursed therefor. No Bank shall be liable for any special, indirect or
consequential damages in connection with any Letter of Credit.

         3.7      Obligation to Reimburse for, or Participate in, Letters of
Credit. Each Borrower's obligation to reimburse the Issuing Bank for payments
and disbursements made by the Issuing Bank under any Letter of Credit requested
by such Borrower honoring a demand for payment by the beneficiary thereunder,
and each Bank's obligation to participate in such payments and disbursements in
accordance with this Agreement, shall be irrevocable, absolute and unconditional
under any and all circumstances, including the following circumstances:

                  (a)      any lack of validity or enforceability of this
Agreement, any Letter of Credit, any LC Application, or any other agreement or
instrument relating thereto (collectively, the "LC Related Documents");

                  (b)      any change in the time, manner or place of payment
of, or in any other term of, all or any of the obligations of any Borrower in
respect of any Letter of Credit or any other amendment or waiver of or any
consent to or departure from all or any of the LC Related Documents;

                  (c)      the existence of any claim, set-off, defense or other
right that any of the Borrowers may have at any time against any beneficiary or
any transferee of any Letter of Credit (or any Person for whom any such
beneficiary or any such transferee may be acting), the Agent, the Issuing Bank
or any other Person, whether in connection with this Agreement or any other
Credit Document, the transactions contemplated by the LC Related Documents or
any unrelated transaction;

                  (d)      any draft, certificate, statement or other document
presented under any Letter of Credit proving to be forged, fraudulent, invalid
or insufficient in any respect or any statement therein being untrue or
inaccurate in any respect other than if such payment resulted from the gross
negligence or willful misconduct of the Agent or the Issuing Bank;

                  (e)      payment by the Issuing Bank under any Letter of
Credit against presentation of a draft or certificate that does not comply with
the terms of any Letter of Credit other than if such payment resulted from the
gross negligence or willful misconduct of the Issuing Bank;

                                       47
<PAGE>
                  (f)      any exchange, release or non-perfection of any
collateral or Lien, or any release or amendment or waiver of or consent to
departure from any guaranty, for all or any of the obligations of any Borrower,
in respect of any Letter of Credit; or

                  (g)      any other circumstance or happening whatsoever
whether or not similar to any of the foregoing, including any other circumstance
that might otherwise constitute a defense available to, or a discharge of, any
Borrower or any account party other than a circumstance constituting gross
negligence or willful misconduct on the part of the Agent or the Issuing Bank.

         3.8      Indemnification by the Banks. The Banks severally agree to
indemnify the Agent, the Issuing Bank and each officer, director, employee,
agent and Affiliate of the Agent or the Issuing Bank ratably according to their
respective Percentage Shares, to the extent not reimbursed by the Borrowers,
from and against any and all actions, causes of action, suits, losses,
liabilities, damages, expenses, attorneys' fees and costs which may at any time
(including, at any time following the payment of any of the Reimbursement
Obligations) be imposed on, incurred by or asserted against such Person in any
way relating to or arising out of the issuance of, transfer of, or payment or
failure to pay under any Letter of Credit or the use of proceeds of any payment
made under any Letter of Credit; provided, however, that no Bank shall be liable
for the payment of any portion of such actions, causes of action, suits, losses,
liabilities, damages and expenses which a court of competent jurisdiction
finally shall have determined in a final proceeding to have arisen solely by
reason of such Person's gross negligence or willful misconduct.

         3.9      Special Provisions Relating to Commercial LCs.

                  (a)      The Borrowers will obtain, or cause to be obtained,
insurance on all goods which are the subject of any Commercial LC. Such
insurance will cover fire and other usual insurable risks and such additional
risks as the Issuing Bank may reasonably request. The Borrowers irrevocably
authorize and empower the Issuing Bank to collect the proceeds of any of the
aforementioned insurance which would be payable to any of the Borrowers and
apply such proceeds, to the extent any of the Borrowers is a loss payee or
otherwise has the right to collect the proceeds of such insurance, against such
Borrower's Reimbursement Obligations to the Banks with respect to the Commercial
LC to which such proceeds relate.

                  (b)      Except as disclosed in writing to the Agent
concurrently with the delivery of the relevant LC Application, each Borrower
represents and warrants to the Banks that it has obtained all import and export
licenses and other governmental approvals required for the goods and the
documents described in any Commercial LC.

                  (c)      (i)      Each Borrower hereby grants to the Agent for
the benefit of the Banks a security interest in such Borrower's right, title and
interest in and to the following described property, whether now owned or
hereafter acquired by the Borrowers (the "LC Collateral"):

                                       48
<PAGE>
                           (A)      All goods and documents described in any
                  Commercial LC;

                           (B)      All negotiable and nonnegotiable documents
                  of title covering any of the above described property;

                           (C)      All rights under contracts of insurance
                  covering any of the above-described property;

                           (D)      All deposit accounts now or hereafter
                  maintained by such Borrower with any Bank with respect to any
                  Commercial LC; and

                           (E)      All proceeds of any of the above described
                  property.

                           (ii)     The LC Collateral secures and will secure
         all obligations and liabilities of such Borrower to the Banks with
         respect to any Commercial LC, whether now existing or hereafter
         incurred or created, whether due or to become due, and whether absolute
         or contingent.

         3.10     Additional Costs in Respect of Letters of Credit. If there
shall be imposed, modified or deemed applicable any tax, reserve, special
deposit or similar requirement against or with respect to or measured by
reference to Letters of Credit issued or to be issued under this Agreement or
participations in such Letters of Credit, and the result shall be to increase
the cost to the Issuing Bank or any other Bank of issuing or maintaining any
Letter of Credit or any participation therein, or reduce any amount receivable
by the Issuing Bank or any other Bank in respect of any Letter of Credit or any
participation therein (which increase in cost, or reduction in amount
receivable, shall be the result of the Issuing Bank's or such other Bank's
reasonable allocation of the aggregate of such increases or reductions resulting
from such event), the Issuing Bank or such other Bank shall notify the Company
through the Agent, and upon demand therefor by the Issuing Bank or such other
Bank through the Agent, each Borrower shall pay to the Issuing Bank or such
other Bank, from time to time as specified by the Issuing Bank or such other
Bank, such additional amounts as shall be sufficient to compensate the Issuing
Bank or such other Bank for such increased costs or reductions in amount. Before
making such demand pursuant to this Section 3.10, the Issuing Bank or such other
Bank will designate a different available Lending Office for the Letter of
Credit or participation or take such other action as the Company may reasonably
request, if such designation or action would avoid the need for, or reduce the
amount of, such compensation and would not, in the sole opinion of the Issuing
Bank or such other Bank, be disadvantageous to the Issuing Bank or such other
Bank. A statement as to such increased costs or reductions in amount incurred by
the Issuing Bank or such other Bank, submitted by the Issuing Bank or such other
Bank to the Company, shall be conclusive as to the amount thereof, absent
manifest error, and may be prepared using any reasonable averaging and
attribution method.

         3.11     Change of Status of Letter of Credit and Indemnity.

                  (a)      If any Letter of Credit is identified as a
Performance SBLC by the Company in its issuance request pursuant to Section
3.3(b), and the Agent or the Issuing

                                       49
<PAGE>
Bank determines prior to the issuance thereof that it should be identified as a
Financial SBLC, then the Agent or the Issuing Bank shall so notify the Company,
and, upon confirmation by the Company that it still requests that such Letter of
Credit be issued, such Letter of Credit shall be issued in accordance with the
terms of this Agreement as a Financial SBLC, and the letter of credit fees
payable in respect thereof shall be those applicable to Financial SBLCs.

                  (b)      If any Letter of Credit is identified as a
Performance SBLC by the Company in its issuance request pursuant to Section
3.3(b), and after the issuance thereof such Letter of Credit is subsequently
identified as a Financial SBLC, whether by the Company, the Issuing Bank, the
Agent, any Bank or any other Person, such Letter of Credit shall thereupon be
reclassified as a Financial SBLC and the letter of credit fees payable with
respect thereto shall thereafter be those applicable to Financial SBLCs and
shall be payable from and after the issuance date of such Letter of Credit. The
Company shall pay to the Agent for the benefit of the Banks within three
Business Days of such re-classification and demand therefore, such additional
fees as may then be due and payable as a result of such reclassification.

                  (c)      TO THE FULLEST EXTENT PERMITTED BY LAW, THE COMPANY
HEREBY AGREES TO INDEMNIFY THE AGENT, THE ISSUING BANK AND THE BANKS AND HOLD
EACH OF THEM HARMLESS FROM AND AGAINST ANY AND ALL CLAIMS, DAMAGES, LOSSES,
LIABILITIES, COSTS OR EXPENSES WHICH MAY ARISE OR BE ASSERTED AGAINST ANY OF
THEM IN CONNECTION WITH, OR AS A CONSEQUENCE OF, ANY MISIDENTIFICATION OF A
LETTER OF CREDIT AS A PERFORMANCE SBLC.

                      AVAILABILITY AND COLLATERAL SECURITY

         4.1      Determination of Gross Borrowing Base; Borrowing Base
Components. At any time while the Obligations are outstanding, there shall be in
effect a "Gross Borrowing Base" determined in accordance with this Section 4.1.
The "Gross Borrowing Base" shall at any time be determined by reference to the
most recent Borrowing Base Certificate in effect, and shall be equal to the sum
(without duplication) of the following components (each, a "Borrowing Base
Component"):

                  (a)      An amount equal to the sum of (A) 100% of cash and
Cash Equivalents of the Obligors in Designated Currencies (excluding any such
cash and Cash Equivalents in the Cash Collateral Account), and (B) 50% of the
Dollar Equivalent (determined using prevailing exchange rates on the date of
delivery of the then most recent Borrowing Base Certificate) of cash of the
Obligors in currencies other than Designated Currencies, which currencies are
approved by the Agent in its sole reasonable discretion; provided that all cash
and Cash Equivalents used to determine this Borrowing Base Component shall be in
an Acceptable Bank Account; and provided further that if the value of the items
set forth in clause (B) exceeds the product of the value of the items set

                                       50
<PAGE>
forth in clause (A) multiplied by three (3), this Borrowing Base Component shall
be deemed to be an amount equal to the product of the value of the items set
forth in clause (A) multiplied by four (4);

                  (b)      85% of Tier 1 Receivables;

                  (c)      70% of Tier 2 Receivables;

                  (d)      40% of Tier 3 Receivables;

                  (e)      65% of the sum of Tier 1 Revenue Accruals plus Tier 1
JV Interests;

                  (f)      50% of the sum of Tier 2 Revenue Accruals plus Tier 2
JV Interests;

                  (g)      30% of the sum of Tier 3 Revenue Accruals plus Tier 3
JV Interests;

                  (h)      65% of Tier 1 Contract Cost and Recognized Income Not
Yet Billed;

                  (i)      50% of Tier 2 Contract Cost and Recognized Income Not
Yet Billed;

                  (j)      30% of Tier 3 Contract Cost and Recognized Income Not
Yet Billed;

                  (k)      40% of Class A Property, Plant and Equipment and
Spare Parts; and;

                  (l)      20% of Class B Property, Plant and Equipment and
Spare Parts;

provided, that (1) in all events the Borrowing Base Components set forth in (a)
through (j) above shall aggregate not less than 50% of the Gross Borrowing Base,
and if the aggregate value attributed as of any date to (k) and (l) above in the
absence of this proviso would cause that not to be the case, then such aggregate
value shall be reduced to the extent necessary to comply with this proviso; and
(2) the sum of Borrowing Base Components (e) through (j) above shall always be
less than 50% of an amount equal to the sum of Borrowing Base Components (a)
through (j) above, and if the aggregate value attributed to Borrowing Base
Components (e) through (j) above in the absence of this proviso would cause that
not to be the case, then such aggregate value shall be reduced to the extent
necessary to comply with this proviso.

         4.2      Borrowing Base Reporting. In addition to any reporting
requirements set forth in Section 8.1, not later than 45 days after and as of
the end of each month, except for December which shall be not later than 60 days
after the end of such month, the Company shall supply the Agent, in form and

calculation of the Gross Borrowing Base and Net Borrowing Base:

                           (i)      a listing, including a reasonable

         or Tier 3 Contract Cost and Recognized Income Not Yet Billed;

                           (v)      a listing of all JV Interests, in each case

         Property, Plant and Equipment and Spare Parts; and

                           (vii)    a listing of Indebtedness comprising Local
         Debt, the Company's calculation of Local Debt, and the Company's
         calculation of Adjusted EBITDA from the preceding fiscal quarter end.

         4.3      Audits of Collateral. On an annual basis commencing on the
date six months following the Closing Date and on each anniversary of such date
thereafter, the Agent may, and shall upon the request of the Required Banks,
conduct, or hire a third party to conduct, on behalf of the Secured Parties and
at the Company's expense, a general audit, a field audit or on-site inspection
of the properties of the Obligors constituting Collateral. In addition,
following the occurrence of an Event of Default and at any time thereafter while
such Event of Default is continuing, the Agent may (and shall, on the
instruction of the Required Banks) conduct, or hire a third party to conduct, on
behalf of the Secured Parties and at the Company's expense, a general audit, a
field audit or on-site inspection of the properties of the Obligors constituting
Collateral. Any

                                       52
<PAGE>
audit of Collateral requested by the Agent or the Required Banks to be conducted
at any time other than the foregoing times shall be done at the expense of the
Banks, but the Obligors shall cooperate with and facilitate such request.

         4.4      Net Borrowing Base. The Agent shall confirm or verify the
Borrower's calculation of the Net Borrowing Base set forth in each Borrowing
Base Certificate delivered pursuant to Section 4.2, and shall promptly notify
each of the Company and the Banks of the results thereof and provide to each
Bank a copy of the related Borrowing Base Certificate.

         4.5      Elections to Participate and Elections to Terminate.

                  (a)      Election to Participate. Each Election to Participate
shall be duly executed on behalf of an electing Designated Subsidiary (the
"Participating Subsidiary") in such number of copies as the Agent may request.
Upon delivery of an Election to Participate and satisfaction of the conditions
precedent set forth in Section 7.3, (i) the Net Borrowing Base shall be
recalculated so as to include therein all values with respect to property and
Local Debt of such Participating Subsidiary, and (ii) each Bank's Commitment
hereunder shall thereafter include a commitment to lend to such Subsidiary or to
issue Letters of Credit for the account of such Participating Subsidiary. The
Agent shall promptly give notice to the Banks and to each of the Obligors of the
receipt of any Election to Participate. Each Obligor understands and agrees that
no further acknowledgement or consent from, or notice to, such Obligor shall be
necessary to give effect to any Election to Participate that becomes effective
in accordance with this Section.

                  (b)      Election to Terminate. Each Election to Terminate
shall be duly executed on behalf of the electing Designated Subsidiary (the
"Terminating Subsidiary") in such number of copies as the Agent may request.
Upon delivery of an Election to Terminate, and as a condition precedent to the
effectiveness thereof, (i) on the effective date of such Election to Terminate
all Obligations of the Terminating Subsidiary shall have been paid in full, (ii)
the Net Borrowing Base shall be recalculated as to exclude all values included
therein with respect to property and Local Debt of such Terminating Subsidiary,
and (iii) any action required under Section 2.6(b) as a result thereof shall
have been taken with respect to the Borrowing Base Exposure then in effect. Upon
the delivery of any Election to Terminate, the Commitment of each Bank to lend
to or to issue Letters of Credit for the account of such Subsidiary shall
terminate. No Permanent Borrower may deliver an Election to Terminate, and no
Election to Terminate with respect to any Permanent Borrower shall be effective
for any purpose. The Agent shall promptly give notice to the Banks and to each
of the Obligors of the receipt of any Election to Terminate. Each Obligor
understands and agrees that no further acknowledgement or consent from, or
notice to, such Obligor shall be necessary to give effect to any Election to
Terminate that becomes effective in accordance with this Section.

         4.6      Voluntary Termination or Reduction of Commitments. The Company
may, upon not less than three Business Days' prior notice to the Agent,
terminate the

                                       53
<PAGE>
Commitments or permanently reduce the Total Commitment by an aggregate minimum
amount of One Million Dollars ($1,000,000) or any multiple of One Hundred
Thousand Dollars ($100,000) in excess thereof; provided, that no such reduction
or termination shall be permitted if, after giving effect thereto and to any
prepayments of the Loans made on the effective date thereof, the then
outstanding Aggregate Exposure would exceed the Total Commitment then in effect;
and provided further, that once reduced in accordance with this Section 4.5, the
Commitments may not thereafter be increased except as provided in Section 4.8.
Any reduction of the Total Commitment shall be applied pro rata to each Bank's
Commitment in accordance with such Bank's Percentage Share. Such notice shall
not thereafter be revocable by the Borrowers, and the Agent shall promptly
notify each Bank thereof and of such Bank's Percentage Share of any reduction of
the Total Commitment.

         4.7      Mandatory Reduction of Total Commitment. Upon the date of
receipt by the Company or any of its Subsidiaries of any Net Cash Proceeds of
any Financing Transaction, the Total Commitment shall automatically and
permanently be reduced by an amount equal to such Net Cash Proceeds. Any
reduction of the Total Commitment pursuant to this Section 4.7 shall be applied
to ratably reduce the Commitment of each Bank by an amount equal to such Bank's
Percentage Share of the amount of the mandatory reduction of the Total
Commitment.

         4.8      Optional Increase of Total Commitment. Provided no Default or
Event of Default has occurred and is continuing, the Company may, with the
consent of the Agent, by written notice to the Agent and the Banks request that
the Total Commitment be increased up to $150,000,000. Upon the Company's receipt
of incremental commitments from such Banks that may agree to provide an
increased Commitment hereunder (there being no obligation on the part of any
Bank at any time hereunder to increase such Bank's Commitment) and/or
commitments from Persons willing to become a Bank with a Commitment hereunder,
then such increase of the Total Commitment shall become effective (the "Increase
Effective Date") when the following conditions precedent have been satisfied and
the Agent shall have notified the parties hereto to such effect:

                  (a)      The Company shall have delivered to the Agent, with
sufficient copies for each Bank (A) a certificate of the Chief Financial Officer
of the Company addressed to the Banks to the effect that, to the best of such
officer's knowledge, (x) no Default or Event of Default has occurred and is
continuing (or would result from the incurrence of the maximum additional
Indebtedness contemplated by this Section 4.8), and (y) all representations and
warranties herein or in any other Credit Document are true and correct in all
material respects with the same effect as if these representations and
warranties had been made on the date of such certificate (it being understood
and agreed that any representation which by its terms is made as of a specified
date shall be required to be true and correct only as of such specified date),
and (B) unless the documentation delivered in connection with the effectiveness
of this Agreement otherwise authorizes Indebtedness hereunder in an aggregate
amount up to $150,000,000, a certificate of the Secretary of each Obligor
certifying that such Obligor has been duly authorized by resolution of such
Obligor's Board of Directors or other governing body to incur any and all
Indebtedness hereunder up to $150,000,000;

                                       54
<PAGE>
                  (b)      A New Bank Agreement for each New Bank shall have
been duly executed by each party thereto;

                  (c)      A Commitment Increase Agreement for each Bank
agreeing to an increase of its current Commitment shall have been duly executed
by each party thereto;

                  (d)      Any Note requested by a New Bank (including a
substitute Note for each Bank requesting it which has agreed to increase its
Commitment) shall have been executed and delivered by each Obligor in
substantially the form of Exhibit A, as appropriate; and

                  (e)      No Loans shall be outstanding hereunder as of the
date such increase is to become effective, or any such Loans which are
outstanding shall be contemporaneously repaid on such date with Loans made
ratably by the Banks in accordance with their new Commitments and Percentage
Shares on such date.

On the Increase Effective Date, each Bank's Letter of Credit Interests on such
date shall automatically be deemed to equal such Bank's Percentage Share of such
Letter of Credit Obligations (such Percentage Share for such Bank to be
determined as of the Increase Effective Date in accordance with its Commitment
on such date as a percentage of the Total Commitment on such date) without
further action by any party.

         4.9      Collateral Security and Post-Closing Items. The Obligations
under this Agreement and all other Credit Documents shall, at all times, be
secured in accordance with the Security Documents. Within the time set forth on
Schedule 4.9 for each listed Post Closing Item, the Obligors shall execute and
deliver to the Agent such Post-Closing Item, together with such other documents
as any Bank through the Agent may reasonably request in connection with
obtaining an Acceptable Security Interest on Collateral covered by Security
Documents which are Post-Closing Items. On and as of the date which is 10 days
after the last date provided on Schedule 4.9, the Company shall deliver to the
Agent for the benefit of the Secured Parties a certificate executed by the Chief
Financial Officer of the Company certifying that each such Security Document
creates an Acceptable Security Interest in all Collateral purported to be
covered thereby.

         4.10     Synthetic Lease. Within 45 days of the Closing Date, the
Company shall either (a) repay in full all outstandings under, and satisfied all
obligations pertaining to, that certain Synthetic Lease Agreement with Brazos
Building & Equipment Limited Partnership (the "Synthetic Lease Agreement"), or
(b) refinance the Synthetic Lease Agreement with a third party lender under
terms reasonably satisfactory to the Agent. Prior to the date the Company does
either (a) or (b) above, the Company agrees that it shall not request Loans and
Letters of Credit hereunder if after giving effect to such request the sum of
any Bank's Percentage Share of the Aggregate Exposure plus any potential
liability or exposure of such Bank under the Synthetic Lease Agreement would
exceed such Bank's Commitment under this Agreement.

                 FEES; PAYMENTS; TAXES; CHANGES IN CIRCUMSTANCES

         5.1 Commitment Fees. In consideration of the Commitments, the Borrowers
jointly and severally agree to pay to the Agent for the ratable account of the
Banks a commitment fee for each day computed by multiplying the Applicable
Margin for Commitment Fees in effect on such day by the average daily unused
portion of the Total Commitment during the calculation period (it being agreed
that outstanding Swingline Loans shall be deemed not to use the Total Commitment
for purposes of this calculation). Such commitment fees shall accrue from the
date of this Agreement to the Maturity Date and shall be due quarterly in
arrears on each Quarterly Payment Date and on the Maturity Date.

         5.2 Agent's Fee. The Company agrees to pay to the Agent for the Agent's
own account on each anniversary of the Closing Date an annual agent's fee in the
amount set forth in the Fee Letter.

         5.3 Letter of Credit Fees.

                  (a) Each Borrower for which a Letter of Credit has been issued
agrees to pay to the Agent for the ratable account of the Banks a letter of
credit fee as follows:

                           (i) in the case of each Performance SBLC, a fee
                  computed by multiplying the Applicable Margin for Performance
                  SBLCs in effect on each day by the undrawn amount of such
                  Performance SBLC on such day;

                           (ii) in the case of each Financial SBLC, a fee
                  computed by multiplying the Applicable Margin for Financial
                  SBLCs in effect on each day by the undrawn amount of such
                  Financial SBLC on each day; and

                           (iii) in the case of each Commercial LC, a fee
                  computed by multiplying the Applicable Margin for Commercial
                  LCs in effect on each day by the undrawn amount of such
                  Commercial LC on such day.

All such letter of credit fees shall accrue on the outstanding amount available
under each such Letter of Credit from its issuance until the date such Letter of
Credit expires or is fully drawn. Such letter of credit fees shall be due
quarterly in arrears on each Quarterly Payment Date.

                  (b) Each Borrower for which a Letter of Credit has been issued
agrees to pay to the Agent for the sole account of the Issuing Bank, an issuance
fee equal to .125% per annum of the face amount of such Letter of Credit,
subject to a minimum of $500. Such issuance fee shall accrue on the outstanding
amount available under such Letter of Credit from the issuance date of such
Letter of Credit to the date such Letter of Credit expires or is fully drawn.
Such issuance fees shall be due quarterly in arrears on each Quarterly Payment
Date.

                                       56
<PAGE>
                  (c) In addition to the fees payable to the Issuing Bank
pursuant to Section 5.3(b), each Borrower agrees to pay to the Agent for the
account of the Issuing Bank all customary administrative, issuance, amendment,
payment and negotiation charges of the Issuing Bank in respect of each Letter of
Credit issued for such Borrower.

         5.4 Computation of Fees and Interest.

                  (a) All computations of interest payable in respect of Base
Rate Loans (to the extent the Base Rate is then determined by the Prime Rate)
shall be made on the basis of the actual number of days elapsed in a year of 365
or 366 days, as the case may be. All other computations of fees and interest
under this Agreement and the other Credit Documents shall be made on the basis
of the actual number of days elapsed in a year of 360 days. Interest and fees
shall accrue during each period during which interest or such fees are computed
from and including the first day thereof to but excluding the last day thereof.
For the purposes of this Agreement and the other Credit Documents, whenever
interest is calculated on the basis of a year of 360 days, each rate of interest
determined pursuant to such calculation expressed as an annual nominal rate for
the purposes of the Interest Act (Canada) is equivalent to such rate as so
determined multiplied by the number of days in the calendar year in which the
same is to be ascertained and divided by 360. The Parties further agree that for
the purposes of the Interest Act (Canada), (i) the principle of deemed
reinvestment of interest shall not apply to any interest calculation under this
Agreement or the other Credit Documents, and (ii) the rates of interest
stipulated in this Agreement are intended to be nominal rates and not effective
rates or yields.

                  (b) The Agent shall, as soon as practicable, notify the
Company and the Banks of each determination of a Eurodollar Rate; provided,
however, that any failure to do so shall not relieve any Borrower or any Bank of
any liability under this Agreement or any other Credit Document. Any change in
the interest rate on a Loan resulting from a change in the Eurodollar Reserve
Percentage, Eurocurrency Liabilities or the Base Rate shall become effective as
of the opening of business on the day on which such change in the Eurodollar
Reserve Percentage, Eurocurrency Liabilities or the Base Rate shall become
effective. The Agent shall, as soon as practicable, notify the Company and the
Banks of the effective date and the amount of each such change; provided,
however, that any failure to do so shall not relieve any Borrower or any Bank of
any liability under this Agreement or any other Credit Document.

                  (c) Each determination of an interest rate by the Agent
pursuant to any provision of this Agreement shall be conclusive and binding on
the Borrowers and the Banks in the absence of manifest error. Promptly following
the last day of each calendar quarter, the Agent shall prepare a Quarterly
Invoice of its calculations of accrued fees and interest at the Base Rate and
deliver such Quarterly Invoice to the Company with a copy to the Banks.

                                       57

         5.5 Payments by the Borrowers.

                  (a) All payments (including prepayments) to be made by the
Borrowers on account of principal, interest and fees shall be made without
deduction, withholding, set-off or counterclaim and (except with respect to
Swingline Loans) shall be made to the Agent, for the account of the Banks
(except as otherwise provided in the Fee Letter or in Section 5.3 or 5.9), at
the Principal Office of the Agent in New York, New York, in Dollars and in
immediately available funds no later than 11:00 a.m. The Agent shall distribute
such payments to each Bank pro rata according to the amount of their respective
Percentage Shares of such principal, interest, fees or other amounts, promptly
upon receipt in like funds as received; provided, that no Bank shall be entitled
to receive a distribution from the Agent of such portions of principal,
interest, or fees to the extent that, at such time of payment by the Borrowers,
such portion exceeds such Bank's share of the interests in the Loan or Letter of
Credit to which such principal, interest, or fee relates. Any payment which is
received by the Agent after 12:00 noon shall be deemed to have been received on
the next succeeding Business Day. The Borrowers shall, at the time any of them
makes each payment under this Agreement or any other Credit Document, specify to
the Agent in detail the Loans or other amounts payable by the Borrowers to which
such payment is to be applied (and in the event that it fails so to specify,
after reasonable efforts to contact the Company such payment shall be applied as
the Agent may designate to the Loans or other amounts then due and payable);
provided that if no Loans or other amounts are then due and payable or an Event
of Default has occurred and is continuing, the Agent may apply any payment to
the Obligations in such order as it may elect in its sole discretion, but
subject to the other terms and conditions of this Agreement. All payments of
principal and interest in respect of Swingline Loans shall be made in
immediately available funds, without deduction, withholding, set-off or
counterclaim, directly to the Swingline Bank at its office in Houston Texas as
follows: ABA# 113011258, A/C # 1000527, Attn: Ann Greer, Ref. Willbros Group,
Inc., or at such other location as the Swingline Bank may direct to the Company
in writing after the date hereof.

                  (b) Whenever any payment under this Agreement or any other
Credit Document shall be stated to be due on a day other than a Business Day,
such payment shall be made on the next succeeding Business Day, and such
extension of time shall in such case be included in the computation of interest
or fees, as the case may be, at the rate in effect on such due date; provided,
however, that if such extension would cause payment of interest on or principal
of Eurodollar Rate Loans to be made in the next following calendar month, such
payment shall be due on the immediately preceding Business Day.

                  (c) Unless the Agent shall have received notice from the
Company, prior to the date on which any payment is due to the Banks under this
Agreement or any other Credit Document, that the Borrowers will not make such
payment in full, the Agent may assume that the Borrowers have made such payment
in full to the Agent on such date and the Agent may, but shall not be so
required, in reliance upon such assumption, cause to be distributed to each Bank
on such due date an amount equal to the amount then due such Bank. If and to the
extent the Borrowers shall not have made such payment in

                                       58
<PAGE>
full to the Agent, each Bank shall repay to the Agent forthwith on demand such
amount distributed to such Bank, together with interest thereon for each day
from the date such amount is distributed to such Bank until the date such Bank
repays such amount to the Agent at the Federal Funds Rate as in effect on such
date. Any such sums not timely paid by such Bank shall accrue interest daily at
a rate per annum equal to the Federal Funds Rate in effect on such date plus 2%.

         5.6 Payments by the Banks to the Agent.

                  (a) Each Bank shall make available to the Agent at the
Principal Office of the Agent in New York, New York, in Dollars and in
immediately available funds for the account of the Borrower requesting a
Borrowing the amount of such Bank's Percentage Share of such Borrowing.

                  (b) Unless the Agent shall have received notice from a Bank on
the Closing Date or, with respect to any Borrowing after the Closing Date, at
least one Business Day prior to the date of such Borrowing that such Bank will
not make available to the Agent for the account of the requesting Borrower such
Bank's Percentage Share of the Borrowing, the Agent may assume that each Bank
has made such amount available to the Agent on the borrowing date and the Agent
may (but shall not be required to), in reliance upon such assumption, make
available to the requesting Borrower on such date a corresponding amount. If and
to the extent any Bank shall not have made its full amount available to the
Agent and the Agent in such circumstances has made available to any Borrower
such amount, such Bank shall, within two Business Days following the date of
such Borrowing, make such amount available to the Agent, together with interest
at the Federal Funds Rate for each day during such period. A certificate of the
Agent submitted to any Bank with respect to amounts owing under this Section
5.6(b) shall be conclusive, absent manifest error. If such amount is so made
available, such payment to the Agent shall constitute such Bank's Loan on the
date of Borrowing for all purposes of this Agreement. If such amount is not made
available to the Agent within two Business Days following the date of such
Borrowing, the Agent shall notify the Company of such failure to fund and, upon
demand by the Agent, the Borrower to which such Loans were extended shall repay
to the Agent such amount, together with interest thereon for each day elapsed
since the date of such Borrowing at a rate per annum equal to the interest rate
applicable at the time to the Loans comprising such Borrowing.

                  (c) The failure of any Bank to make any Loan on any date of
Borrowing shall not relieve any other Bank of the obligation under this
Agreement to make a Loan on the date of such Borrowing, but no Bank shall be
responsible for the failure of any other Bank to make the Loan to be made by
such other Bank on the date of any Borrowing.

         5.7 Default Interest. Any amounts payable hereunder that are not paid
when due shall accrue interest from the due date until paid in full at the
Default Rate, and such interest shall be due and payable on demand.

                                       59

         5.8 Taxes.

                  (a) Subject to Section 5.8(g), any and all payments by any
Obligor under the Credit Documents shall be made free and clear of, and without
deduction or withholding for, any and all present or future taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, excluding, in the case of each Bank and the Agent, such taxes
(including income taxes or franchise taxes) as are imposed on or measured by
such Bank's or the Agent's net income by the jurisdiction under the laws of
which such Bank or the Agent, as the case may be, is organized or maintains a
Lending Office or any political subdivision thereof (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities being
herein referred to as "Taxes").

                  (b) In addition, each Obligor shall pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made under any Credit Document or
from the execution, delivery or registration of, or otherwise with respect to,
this Agreement or any other Credit Document (herein referred to as "Other
Taxes").

                  (c) Subject to Section 5.8(g), each Obligor shall indemnify
and hold harmless each Bank and the Agent for the full amount of Taxes or Other
Taxes (including any Taxes or Other Taxes imposed by any jurisdiction on amounts
payable under this Section 5.8) paid by the Bank or the Agent and any liability
(including penalties, interest, additions to tax and expenses) arising therefrom
or with respect thereto, whether or not such Taxes or Other Taxes were correctly
or legally asserted. Payment under this indemnification shall be made within 30
days from the date any Bank or the Agent makes written demand therefor.

                  (d) If any Obligor shall be required by law to deduct or
withhold any Taxes or Other Taxes from or in respect of any sum payable under
this Agreement or any other Credit Document to any Bank or the Agent, then,
subject to Section 5.8(g):

                           (i) the sum payable shall be increased as necessary
                  so that after making all required deductions (including
                  deductions applicable to additional sums payable under this
                  Section 5.8 and, notwithstanding any exclusion from Taxes in
                  Section 5.8(a) for net income taxes of the Banks, including in
                  the case of non-U.S. withholding tax imposed at rates of 5% or
                  greater, any U.S. tax, including taxes on net income,
                  attributable to such increase) such Bank or the Agent, as the
                  case may be, receives an amount equal to the sum it would have
                  received had no such deductions been required;

                           (ii) the Obligor shall make such deductions; and

                           (iii) the Obligor shall pay the full amount deducted
                  to the relevant taxation authority or other authority on
                  behalf of any Bank in accordance with applicable law.

                                       60
<PAGE>
                  (e) Within 30 days after the date of any payment by a Obligor
of Taxes or Other Taxes, such Obligor shall furnish to the Agent the original or
a certified copy of a receipt evidencing payment thereof, or other evidence of
payment satisfactory to the Agent.

                  (f) Each Bank which is a foreign Person (i.e., a person other
than a United States person for U. S. Federal income tax purposes) agrees that:

                           (i) It shall, no later than the Closing Date (or, in
                  the case of a Bank which becomes a Party pursuant to Section
                  13.7 after the Closing Date, the date upon which the Bank
                  becomes a Party) deliver to the Company through the Agent:

                                    (A) if any Lending Office is located in the
                           U. S., two accurate and complete signed originals of
                           Internal Revenue Service Form W-8ECI ("Form W-8ECI")
                           or any successor thereto, and

                                    (B) if any Lending Office is located outside
                           the U. S., two accurate and complete signed originals
                           of Internal Revenue Service Form W-8BEN ("Form
                           W-8BEN") or any successor thereto,

                  in each case indicating that the Bank is on the date of
                  delivery thereof entitled to receive payments of principal,
                  interest and fees for the account of such Lending Office or
                  Offices under this Agreement free from withholding of U. S.
                  Federal income tax.

                           (ii) If at any time a Bank changes its Lending Office
                  or Offices or selects an additional Lending Office as herein
                  provided, it shall, at the same time or reasonably promptly
                  thereafter, deliver to the Company through the Agent in
                  replacement for, or in addition to, the forms previously
                  delivered by it under this Agreement:

                                    (A) if such changed or additional Lending
                           Office is located in the U. S., two accurate and
                           complete signed originals of Form W-8ECI, or

                                    (B) otherwise, two accurate and complete
                           signed originals of Form W-8BEN,

                  in each case indicating that the Bank is on the date of
                  delivery thereof entitled to receive payments of principal,
                  interest and fees for the account of such changed or
                  additional Lending Office or Offices under this Agreement free
                  from withholding of U. S. Federal income tax.

                           (iii) It shall, before or promptly after the
                  occurrence of any event (including the passing of time but
                  excluding any event mentioned in clause (ii) above) requiring
                  a change in the most recent Form W-8ECI or Form W-8BEN
                  previously delivered by the Bank and if the delivery of the
                  same be lawful, deliver to the Obligors through the Agent two
                  accurate and complete original signed

                                       61
<PAGE>
                  copies of Form W-8ECI or Form W-8BEN in replacement for the
                  forms previously delivered by the Bank.

                           (iv) It shall, promptly upon the Obligors' reasonable
                  request to that effect, deliver to the Company (through the
                  Agent) such other forms or similar documentation as may be
                  required from time to time by any applicable law, treaty, rule
                  or regulation in order to establish such Bank's tax status for
                  withholding purposes.

                           (v) If such Bank claims exemption from withholding
                  tax under a U. S. tax treaty by providing a Form W-8BEN and
                  such Bank sells or grants a participation of all or part of
                  its rights under this Agreement, such Bank shall notify the
                  Agent of the percentage amount in which it is no longer the
                  beneficial owner under this Agreement. To the extent of this
                  percentage amount, the Agent shall treat such Bank's Form
                  W-8BEN as no longer in compliance with this Section 5.8(f). In
                  the event a Bank claiming exemption from U. S. withholding tax
                  by filing Form W-8ECI with the Agent, sells or grants a
                  participation in its rights under this Agreement, such Bank
                  agrees to undertake sole responsibility for complying with the
                  withholding tax requirements imposed by Sections 1441 and 1442
                  of the Code.

                           (vi) Without limiting or restricting any Bank's right
                  under Section 5.8(d) to increased amounts from the Obligors
                  upon satisfaction of such Bank's obligations under the
                  provisions of this Section 5.8(f), if such Bank is entitled to
                  a reduction in the applicable withholding tax, the Agent may
                  withhold from any interest to such Bank an amount equivalent
                  to the applicable withholding tax after taking into account
                  such reduction. If the forms or other documentation required
                  by subparagraph (i) are not delivered to the Agent, then the
                  Agent may withhold from any interest payment to the Bank not
                  providing such forms or other documentation an amount
                  equivalent to the applicable withholding tax. In addition, the
                  Agent may also withhold against periodic payments other than
                  interest payments to the extent United States withholding tax
                  is not eliminated by obtaining Form W-ECI or Form W-8BEN.

                           (vii) if the Internal Revenue Service or any
                  authority of the U.S. or any other jurisdiction asserts a
                  claim that the Agent or any Obligor did not properly withhold
                  tax from amounts paid to or for the account of any Bank (for
                  example only, because the appropriate form was not delivered,
                  was not properly executed, or because such Bank failed to
                  notify the Agent of a change in circumstances which rendered
                  the exemption from withholding tax ineffective), such Bank
                  shall indemnify the Agent and/or such Obligor, fully for all
                  amounts paid, directly or indirectly, by the Agent and/or such
                  Obligor, as tax or otherwise, including penalties and
                  interest, and including any taxes imposed by any jurisdiction
                  on the amounts payable to the Agent or such Obligor under this
                  Section 5.8(f), together with all costs, expenses and
                  attorneys' fees (including allocated costs for in-house staff
                  counsel).

                                       62
<PAGE>
                  (g) The Obligors will not be required to pay any additional
amounts in respect of U. S. Federal income tax pursuant to Section 5.8(d) to any
Bank for the account of any Lending Office of such Bank:

                           (i) if the obligation to pay such additional amounts
                  would not have arisen but for a failure by such Bank to comply
                  with its obligations under Section 5.8(f) in respect of such
                  Lending Office;

                           (ii) if such Bank shall have delivered to the Company
                  a Form 4224 in respect of such Lending Office pursuant to
                  Section 5.8(f)(i)(A), and the Bank shall not at any time be
                  entitled to exemption from deduction or withholding of U. S.
                  Federal income tax in respect of payments by the Obligors
                  under this Agreement and the other Credit Documents for the
                  account of such Lending Office for any reason other than a
                  change in U. S. law or regulations or in the official
                  interpretation of such law or regulations by any Governmental
                  Authority charged with the interpretation or administration
                  thereof (whether or not having the force of law) after the
                  date of delivery of such Form 4224 and Form W-9; or

                           (iii) if such Bank shall have delivered to the
                  Company a Form 1001 and Form W-8 in respect of such Lending
                  Office pursuant to Section 5.8(f)(i)(B), and such Bank shall
                  not at any time be entitled to exemption from deduction or
                  withholding of United States Federal income tax in respect of
                  payments by the Obligors under this Agreement and the other
                  Credit Documents for the account of such Lending Office for
                  any reason other than a change in United States law or
                  regulations or any applicable tax treaty or regulations or in
                  the official interpretation of any such law, treaty or
                  regulations by any Governmental Authority charged with the
                  interpretation or administration thereof (whether or not
                  having the force of law) after the date of delivery of such
                  Form 1001 and Form W-8.

                  (h) If, at any time, any Obligor requests any Bank to deliver
any forms or other documentation pursuant to Section 5.8(f)(iv), then such
Obligor shall, on demand of such Bank through the Agent, reimburse such Bank for
any costs or expenses reasonably incurred by such Bank in the preparation or
delivery of such forms or other documentation.

                  (i) If a Obligor is required to pay additional amounts to any
Bank or the Agent pursuant to Section 5.8(d), then such Bank shall use
reasonable efforts (consistent with legal and regulatory restrictions) to change
the jurisdiction of its Lending Office so as to eliminate any such additional
payment by the Obligors which may thereafter accrue if such change in the
judgment of such Bank is not otherwise disadvantageous to such Bank.

                  (j) The agreements and obligations of the Obligors contained
in this Section 5.8 shall survive the payment in full of all Obligations.

                                       63
<PAGE>
         5.9 Sharing of Payments, Etc. If, other than as provided in Sections
3.10, 5.8 and 5.11, any Bank shall obtain any payment (whether voluntary,
involuntary, through the exercise of any right of set-off, or otherwise) on
account of the Loans made by it or its Letter of Credit Interests in excess of
its Percentage Share of the Aggregate Exposure, such Bank shall forthwith
purchase from the other Banks such participations in the Loans or the Letter of
Credit Interests of the other Banks as shall be necessary to cause such
purchasing Bank to share the excess payment ratably with each of them; provided,
however, that if all or any portion of such excess payment is thereafter
recovered from such purchasing Bank, such purchase by such Bank from each other
Bank shall be fully or partially rescinded and each other Bank shall repay to
the purchasing Bank the purchase price paid thereto to the extent of such
repaying Bank's recovery, together with an amount equal to such paying Bank's
Percentage Share (according to the proportion of (a) the amount of such paying
Bank's required repayment to (b) the total amount so recovered from the
purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered. Each Obligor agrees
that any Bank so purchasing a participation from another Bank pursuant to the
provisions of this Section 5.9 may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off) with respect
to such participation as fully as if such Bank were the direct creditor of such
Obligor in the amount of such participation.

         5.10 Illegality.

                  (a) If any Bank shall determine that any Legal Requirement or
any change therein or in the interpretation or administration thereof has made
it unlawful, or that any central bank or other Governmental Authority has
asserted that it is unlawful, for any Bank or its Lending Office to make
Eurodollar Rate Loans, then, on notice thereof by such Bank to the Company
through the Agent, the obligation of such Bank to make Eurodollar Rate Loans
shall be suspended until the notifying Bank shall have notified the Agent and
the Company that the circumstances giving rise to such determination no longer
exist, and during such suspension period such Bank shall make Base Rate Loans.

                  (b) If any Bank shall determine that it is unlawful to
maintain any Eurodollar Rate Loan, the Borrowers shall prepay in full all
Eurodollar Rate Loans of such Bank then outstanding, together with interest
accrued thereon, either on the last day of the Interest Period thereof if such
Bank may lawfully continue to maintain such Eurodollar Rate Loans to such day,
or immediately, if such Bank may not lawfully continue to maintain such
Eurodollar Rate Loans, together with any amounts required to be paid in
connection therewith pursuant to Section 5.11.

                  (c) If any Borrower is required to prepay any Eurodollar Rate
Loan immediately as provided in Section 5.10(b), then, concurrently with such
prepayment, such Borrower shall borrow from the affected Bank, in the amount of
such repayment, a Base Rate Loan having as its Interest Payment Date the same
Interest Payment Date as the Eurodollar Rate Loan which was prepaid.

                  (d) Before giving any notice to the Agent pursuant to this
Section 5.10, the affected Bank shall designate a different Lending Office with
respect to its

                                       64
<PAGE>
Eurodollar Rate Loans if such designation will avoid the need for giving such
notice or making such demand and will not, in the judgment of such Bank, be
illegal or otherwise disadvantageous to such Bank.

         5.11 Increased Costs and Reduction of Return.

                  (a) Increased Costs. If any Bank shall determine that, due to
either (i) the introduction of or any change (other than any change by way of
imposition of or increase in reserve requirements included in the Eurodollar
Reserve Percentage) in or in the interpretation of any law, regulation or other
Legal Requirement (including changes in reserve, special deposit or similar
requirements imposed by a Governmental Authority) or (ii) the compliance with
any guideline or request from any central bank or other Governmental Authority
(whether or not having the force of law), there shall be any increase in the
cost to such Bank of agreeing to make or making, funding or maintaining any
Eurodollar Rate Loans, then the Borrowers shall be jointly and severally liable
for, and shall from time to time, upon demand therefor by such Bank (with a copy
of such demand to the Agent), jointly and severally pay to the Agent for the
account of such Bank, additional amounts as are sufficient to compensate such
Bank for such increased costs.

                  (b) Capital Adequacy. If any Bank shall have determined that

                           (i) the adoption after the date of this Agreement or
                  the effectiveness after the date of this Agreement (regardless
                  of whether previously announced) of any applicable Legal
                  Requirement or treaty regarding capital adequacy, or

                           (ii) any change after the date of this Agreement in
                  any existing or future Legal Requirement or treaty regarding
                  capital adequacy, or

                           (iii) any change after the date of this Agreement in
                  the interpretation or administration of any existing or future
                  Legal Requirement or treaty regarding capital adequacy by any
                  Governmental Authority or comparable agency charged with the
                  interpretation or administration thereof, or

                           (iv) compliance by any Bank (or its Lending Office)
                  with any request or directive after the date of this Agreement
                  regarding capital adequacy (whether or not having the force of
                  law) of any such Governmental Authority or comparable agency
                  has or would have the effect of reducing the rate of return on
                  the capital of such Bank (or any holding company of which such
                  Bank is a part) as a consequence of its obligations under this
                  Agreement and the other Credit Documents to a level below that
                  which such Bank or holding company could have achieved but for
                  such adoption, change or compliance by an amount deemed by
                  such Bank or holding company to be material, then, from time
                  to time, on demand by such Bank (with a copy to the Agent),

the Borrowers shall pay to such Bank such additional amount or amounts as will
compensate such Bank or holding company for such reduction. The certificate of
any

                                       65
<PAGE>
Bank setting forth such amount or amounts as shall be necessary to compensate it
and the basis therefor shall cover amounts accruing under this Section 5.11
shall be conclusive and binding, absent manifest error. The Company shall pay
the amount shown as due on any such certificate upon delivery of such
certificate. In preparing such certificate, a Bank may take into consideration
such Bank's and such holding company's policies with respect to capital
adequacy, employ such assumptions and allocations of costs and expenses as it
shall in good faith deem reasonable, and use any reasonable averaging and
attribution method.

                  (c) Taxation. The Borrowers shall pay to the Agent, on demand,
for the account of such Bank, from time to time such amounts as any Bank may
reasonably determine to be necessary to compensate it for any costs incurred by
such Bank which such Bank reasonably determines are attributable to its making
or maintaining any Loan hereunder or its obligation to make or maintain any such
Loan hereunder, or any reduction in any amount receivable by such Bank hereunder
in respect of any of such Loans or such obligation, in each case resulting from
any Regulatory Change which:

                           (i) subjects such Bank (or makes it apparent that
                  such Bank is subject) to the imposition of (or any increase
                  in) any tax (including any U. S. interest equalization tax),
                  levy, impost, duty, charge, or fee (and all liabilities with
                  respect to the foregoing), or any deduction or withholding for
                  any Taxes on or from the payment due under any Letter of
                  Credit or Loan or other amounts due hereunder (other than
                  income and franchise taxes of the jurisdiction (or any
                  subdivision thereof) in which such Bank has an office or a
                  Lending Office); or

                           (ii) changes the basis of taxation of any amounts
                  payable to such Bank under this Agreement or any Credit
                  Document in respect of any of such Letters of Credit or Loans,
                  other than changes which affect taxes measured by or imposed
                  on the overall net income or franchise taxes of such Bank or
                  of its Lending Office for any of such Letters of Credit or
                  Loans by the jurisdiction (or any subdivision thereof) in
                  which such Bank has an office or such Applicable Lending
                  Office; or

                           (iii) imposes any other condition materially
                  affecting this Agreement (or any of such extensions of credit
                  or liabilities).

Each Bank will notify the Company through the Agent of any event occurring after
the date of this Agreement which will entitle such Bank to compensation pursuant
to this Section as promptly as practicable after it obtains knowledge thereof
and determines to request such compensation.

         5.12 Funding Losses. Each Borrower agrees jointly and severally to
reimburse each Bank and to hold each Bank harmless from any loss or expense
which such Bank may sustain or incur as a consequence of the following:

                                       66
<PAGE>
                  (a) the failure of any Borrower to make any payment or
prepayment of principal of any Eurodollar Rate Loan when due (including payments
made after any acceleration thereof);

                  (b) the failure of any Borrower to borrow, continue or convert
a Revolving Loan after the Company has given (or is deemed to have given) a
Notice of Revolving Borrowing or a Notice of Conversion/Continuation;

                  (c) the failure of any Borrower to make any prepayment after
such Borrower has given a notice in accordance with Section 2.5; or

                  (d) the prepayment of a Eurodollar Rate Loan on a day which is
not the last day of the Interest Period with respect thereto; including any such
loss or expense arising from the liquidation or reemployment of funds obtained
by it to maintain its Eurodollar Rate Loans or from fees payable to terminate
the deposits from which such funds were obtained. This covenant shall survive
payment in full of all other Obligations and the termination of the Credit
Documents.

         5.13 Eurodollar Rate Protection. In the event that (a) the Agent shall
have determined (which determination shall be conclusive and binding upon the
Borrowers) that for any reason adequate and reasonable means do not exist for
ascertaining the Eurodollar Rate for any requested Interest Period with respect
to a proposed Loan that a Borrower has requested be made as a Eurodollar Rate
Loan, or (b) the Agent shall have determined (which determination shall be
conclusive and binding upon the Borrowers) that the Eurodollar Rate applicable
for any requested Interest Period with respect to a proposed Loan that a
Borrower has requested be made as a Eurodollar Rate Loan does not adequately and
fairly reflect the cost to such Bank of funding such Loan, the Agent shall
forthwith give notice of such determination to the Company and each Bank at
least one day prior to the proposed borrowing date for such Eurodollar Rate
Loan. If such notice is given, any requested Eurodollar Rate Loan shall be made
as a Base Rate Loan. Until such notice has been withdrawn by the Agent, no
further Eurodollar Rate Loans may be requested by the Borrowers and on the
Interest Payment Date of any Eurodollar Rate Loan then outstanding and so
affected such outstanding Loan shall be converted into a Base Rate Loan.

         5.14 Certificates of Banks. Any Bank claiming reimbursement or
compensation pursuant to this Article V shall deliver to the Company and the
Agent a certificate setting forth in reasonable detail the computation of the
amount payable to such Bank under this Agreement and such certificate shall be
conclusive and binding on the Borrowers in the absence of manifest error.

         5.15 Certain Notices Irrevocable. Notices to the Agent of any
termination or reduction of the Commitments, of prepayments of Loans and of the
duration of Interest Periods, and each Notice of Borrowing, each LC Application
and each Notice of Conversion/Continuation shall be irrevocable, and any such
notice shall be effective only if timely received by the Agent and, in the case
of a Notice of Swingline Borrowing, by the Swingline Bank.

        5.16 Subordination of Intercompany Debt. Each Obligor hereby expressly
covenants and agrees for the benefit of the Agent and the Banks that all
obligations and liabilities of the Company and its Subsidiaries to any Obligor
of whatsoever description (collectively herein called, the "Subordinated
Obligations"), including without limitation, all intercompany receivables of
such Obligor from the Company or any of its Subsidiaries, shall be subordinated
and junior in right of payment to the Obligations outstanding at any time,
whether or not secured by any Lien (collectively herein called, the "Senior
Obligations"), as set forth in this Section 5.16.

                  (a) Subordination. Each Obligor which now or hereafter has
Subordinated Obligations (a "Payor") agrees, and shall cause each holder of such
Subordinated Obligations (a "Payee") to agree (and any Payee which is an Obligor
hereunder, does so agree) that all Subordinated Obligations are subordinated, to
the extent and in the manner provided herein, to the prior payment in full of
all Senior Obligations. This Section 5.16 is intended for the benefit of all
persons who hold, or, in reliance on the provisions of this Section, become
holders of, or continue to hold, Senior Obligations, and each such person shall
be entitled to enforce such provision. No amendment or other modification of the
provisions of this Section 5.16 shall be effective against any holder of Senior
Obligations who has not consented thereto.

                  (b) Seniority of Payment. Upon the maturity of any Senior
Obligations by lapse of time, acceleration (unless waived) or otherwise
(including all installments of principal and interest), all Senior Obligations
then due and owing shall first be paid in full, or such payment duly provided
for in cash or in a manner satisfactory to all of the holders of such Senior
Obligations, before any payment is made on account of any amount owing under any
Subordinated Obligations.

                  (c) No Payment After Default. Upon the happening of any
Default or Event of Default, then, unless and until such Default or Event of
Default shall have been cured or waived or shall have ceased to exist, (i) no
payment shall be made by any Payor with respect to any amount owing in respect
of Subordinated Obligations, (ii) no set-off or reduction of any Obligations
shall be made because of Subordinated Obligations, and (iii) if the Agent shall
so request, each Payee shall collect and receive Subordinated Obligations as
trustee for the Agent and the Banks and pay over all sums so collected to the
Agent and the Banks on account of the Obligations but without reducing or
affecting in any manner the liability of such Payee under this Agreement in any
way.

                  (d) Holding in Trust. In the event that notwithstanding the
provisions of this Section 5.16 any Payor shall make any payment to any Payee on
account of any Subordinated Obligations at any time when such payment is
prohibited pursuant to clauses (a) through (c) of this Section 5.16, then, such
payment shall be held by the Payee in trust for the benefit of, and shall be
paid forthwith over and delivered to, the Agent for the benefit of the holders
of Senior Obligations (pro rata as to each of such holders on the basis of the
respective amounts of Senior Obligations held by them) for application to the
payment of all Senior Obligations remaining unpaid to the extent necessary to
pay all Senior Obligations in full accordance with its terms, after giving
effect to any concurrent

                                       68
<PAGE>
payment or distribution to or for the holders of Senior Obligations. Each Payor
shall give prompt written notice to each Payee of any Default or Event of
Default that has occurred.

                  (e) Rights upon Dissolution. Upon any distribution of assets
of any Payor in any dissolution, winding up, liquidation or reorganization for
the benefit of creditors of such Payor (whether in bankruptcy, insolvency or
receivership proceedings or upon an assignment for the benefit of creditors or
otherwise):

                  (i) the holders of all Senior Obligations shall first be
         entitled to receive payments in full of all Senior Obligations
         (including without limitation interest accruing after the commencement
         of any such proceeding at the rate specified in the documentation
         governing the terms of the respective Senior Obligations) in cash or in
         a manner satisfactory to all of its holders before the Payees are
         entitled to receive any payment on account of any amount owing under
         any Subordinated Obligations;

                  (ii) any payment or distribution of assets of any Payor of any
         kind or character, whether in cash, property or securities, to which a
         Payee would be entitled except for the provisions of this Section 5.16,
         including any such payment or distribution which may be payable or
         deliverable by reason of the payment of any other indebtedness of a
         Payor being subordinated to the payment of any amount owing in respect
         of any Subordinated Obligations, shall be paid by the liquidating
         trustee or agent or other person making such payment or distribution
         directly to the holders of the Senior Obligations or their
         representative, or to the trustee under any indenture under which
         Senior Obligations may have been issued (pro rata as to each such
         holder, representative or trustee on the basis of the representative
         amounts of unpaid Senior Obligations held or represented by each), to
         the extent necessary to make payment in full of all Senior Obligations
         remaining unpaid, after giving effect to any concurrent payment or
         distribution or provision therefor to the holders of such Senior
         Obligations, except that a Payee would be entitled to receive
         securities that are subordinated to Senior Obligations to at least the
         same extent as the Subordinated Obligations; and

                  (iii) in the event that notwithstanding the foregoing
         provisions of this Section 5.16, any payment or distribution of assets
         of any Payor of any kind or character, whether in cash, property or
         securities, including any such payment or distribution which may be
         payable or deliverable by reason of the payment of any other
         indebtedness of such Payor being subordinated to the payment of any
         amount owing in respect of the Subordinated Obligations, shall be
         received by such Payee on account of any amount owing in respect of the
         Subordinated Obligations before all Senior Obligations is paid in full,
         such payment or distribution shall be received and held in trust for
         and shall be paid over to the Agent for the pro rata benefit of the
         holders of the Senior Obligations remaining unpaid or unprovided for or
         their representative, for application to the payment of such Senior
         Obligations until all such Senior Obligations shall have been paid in
         full, except that such Payee would be entitled to receive securities
         that are

                                       69
<PAGE>
         subordinated to Senior Obligations to at least the same extent as the
         Subordinated Obligations.

                  (f) Subrogation Rights. On and after the payment in full of
all Senior Obligations, each Payee shall be subrogated equally and ratably to
the rights of the holders of the Senior Obligations to receive payments or
distributions of assets of a Payor, whether in cash, property or securities,
applicable to the Senior Obligations until all amounts owing in respect of
Subordinated Obligations shall be paid in full, and for the purpose of such
subrogation no payments or distributions to the holders of the Senior
Obligations by or on behalf of any Payor or by on behalf of any Payee by virtue
of this Section which otherwise would have been made to such Payee shall, as
between such Payor, its creditors other than holders of the Senior Obligations
and such Payee, be deemed to be payment by such Payor to or on account of the
Senior Obligations.

                  (g) Intended Beneficiaries. The provisions of this Section
5.16 are intended solely for the purpose of defining the relative rights of each
Payee, on the one hand, and the holders of the Senior Obligations, on the other
hand, and nothing contained in this Section 5.16 or elsewhere in any
documentation related to the Subordinated Obligations is intended to or shall
impair as between any Payor, its creditors other than holders of Senior
Obligations, and any Payee, the obligation of such Payor, which is absolute and
unconditional, to pay to such Payee the principal of, interest or premium, if
any, on any Subordinated Obligations as and when the same shall become due and
payable in accordance with their terms, or is intended to or shall affect the
relative rights of such Payee and creditors of such Payor other than the holders
of the Senior Obligations, nor shall anything herein or therein prevent such
Payee from exercising all remedies otherwise permitted by applicable law upon
default under any documentation evidencing the Subordinated Obligations, subject
to the rights, if any, under this Section 5.16 of the holders of Senior
Obligations in respect of cash, property or securities of any Payor received
upon the exercise of any such remedy. Upon any distribution of assets of any
Payor referred to in this Section 5.16, each Payee shall be entitled to rely
upon any order or decree made by any court of competent jurisdiction in which
such dissolution, winding up, liquidation or reorganization proceedings are
pending, or a certificate of the liquidating trustee or agent or other person
making any distribution to such Payee for the purpose of ascertaining the
persons entitled to participate in such distribution, the holders of the Senior
Obligations and other indebtedness of such Payor, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon, and all other facts
pertinent thereto or to this Section 5.16.

                  (h) Subordination Rights Not Impaired. The right or interest
of any present or future holders of any Senior Obligations, and all agreements
and obligations of any Payee under this Section 5.16, shall remain in full force
and effect irrespective of: (i) any change in the time, manner or place of
payment of, or in any other term in respect of, all or any of the Senior
Obligations, or any amendment or waiver of any agreement or instrument related
thereto; (ii) any exchange or release of, or non-perfection of any lien on or
security interest in, any collateral, or any release from, amendment or waiver
of or consent to departure from any guaranty, for all or any of the Senior
Obligations; (iii) any other circumstance which might otherwise constitute a
defense available to or discharge

                                       70
<PAGE>
of such Payee in respect of the provisions of this Section 5.16; or (iv) any act
or failure to act on the part of any Payor or by any act or failure to act, in
good faith, by any holder of Senior Obligations, or by any noncompliance by such
Payor with the terms of the Subordinated Obligations, regardless of any
knowledge thereof which such Payee may have or be otherwise charged with.

                  (i) Other Provisions Subject Hereto. Except as expressly
stated in this Section 5.16, notwithstanding anything contained in any
documentation related to the Subordinated Obligations to the contrary, all the
provisions of such documentation are subject to the provisions of this Section
5.16. The provisions of this Section 5.16 shall continue to be effective or
shall be reinstated, as the case may be, if at any time any payment in respect
of Senior Obligations is rescinded or must otherwise be returned on the
insolvency, bankruptcy or reorganization of any Payor or otherwise, all as
though such payment had not been made.

                  (j) Pledge of Subordinated Obligations. Each Payor
acknowledges that each Payee which is an Obligor has assigned and pledged it
rights in respect of the Subordinated Obligations as collateral security for the
Obligations of such Payee. Each Payor hereby consents to such assignment and
pledge and agrees that all payments in respect of the Subordinated Obligations
shall, upon the request of the Agent, be made directly to the Agent for the
benefit of the Banks as the Agent may instruct. By its execution of this
Agreement each Payee which is an Obligor acknowledges that any payments so
received by the Agent from a Payor which is an Obligor shall ratably reduce the
outstanding balance of the Subordinated Obligations of such Payor.

                         REPRESENTATIONS AND WARRANTIES

                  (a) Schedule 6.7 lists all Plans maintained or sponsored by
the Company or any of its Subsidiaries (or to which the Company or any of its
Subsidiaries is obligated to contribute), and separately identifies Plans
intended to be Qualified Plans and Multiemployer Plans. Each of such Plans or
written descriptions thereof provided to the Agent is true and complete in all
material respects.

                  (b) Each such Plan is in compliance in all material respects
with the applicable provisions of ERISA, the Code and other Legal Requirements,
including all requirements under the Code or ERISA for filing reports (which are
true and correct in all material respects as of the date filed), and all
benefits have been paid in accordance with the provisions of each such Plan.

                  (c) Each such Qualified Plan has been determined by the
Internal Revenue Service to qualify under Section 401 of the Code, and the
trusts created thereunder have been determined to be exempt from tax under the
provisions of Section 501 of the Code, and, to the knowledge of the Obligors,
nothing has occurred which would cause the loss of such qualification or
tax-exempt status.

                  (d) Except as set forth in Schedule 6.7, there is no
outstanding liability under Title IV of ERISA with respect to any Plan

such further acts, deeds, conveyances, security agreements, mortgages,
assignments, estoppel certificates, financing statements and continuations
thereof, termination statements, notices of assignment, transfers, certificates,
consents, confirmations, legal opinions, assurances and other writings and
instruments as the Agent or any Bank (through the Agent) may reasonably require
from time to time in order (i) to carry out more effectively the purposes of
this Agreement or any other Credit Document, (ii) to subject to the Liens
created by any of the Security Documents any of the properties, rights or
interests covered by any of the Security Documents, (iii) to perfect and
maintain the validity, effectiveness and priority of any of the Security
Documents and the Liens intended to be created thereby, (iv) to better assure,
convey, grant, assign, transfer, preserve, protect and confirm to the Agent and

         8.13 Certain Obligations Respecting Certain New Subsidiaries. The
Company will, and will cause each of its Subsidiaries to, take such action from
time to time as shall be necessary to ensure that the Company or one of its
Subsidiaries which has executed and delivered to the Agent an appropriate Credit
Document pursuant to Section 8.14 at all times retains the right to vote all of
the issued and outstanding shares of each class of stock of or other equity
interest owned by the Company or any of its Subsidiaries in each New Material
Subsidiary. Without limiting the generality of the foregoing, neither the
Company nor any Subsidiary of the Company shall sell, transfer or otherwise
dispose of any shares of stock or other equity interest in or any right to vote
any shares of stock or other equity interest in any New Material Subsidiary
owned by it, nor permit any New Material Subsidiary to issue any shares of stock
of any class whatsoever or other equity interest to any Person which would
reduce the percentage of equity of such New Material Subsidiary owned by the
Company or any of its Subsidiaries. In the event that any such additional shares
of stock or other equity interest shall be issued by any New Material Subsidiary
to the Company or any Subsidiary of the Company, the Company shall forthwith
deliver or cause to be delivered to the Agent pursuant to a pledge agreement (or
other Credit Document of similar effect) all certificates and other writings
evidencing such shares of stock or other equity interest, accompanied by undated
stock powers (or other instruments of similar effect) executed in blank, and
shall take or cause to be taken all such other action as the Agent shall request
to create, perfect, protect and realize upon the security interest created
therein pursuant to the pledge agreement (or other Credit Document of similar
effect).

         8.14 New Material Subsidiaries. Within 30 days after the creation,
formation or acquisition by the Company or any of its Subsidiaries of any
interest in any New Material Subsidiary, the Company shall:

                                       92
<PAGE>
                  (a) execute and deliver, and cause each of the Company's
Subsidiaries owning any of the outstanding capital stock or other equity
interest of such New Material Subsidiary to execute and deliver, to the Agent on
behalf of the Banks an agreement, substantially similar to the Pledge
Agreements, with such changes as shall be necessary in the circumstances,
pursuant to which all of the outstanding capital stock or other equity interest
of such New Material Subsidiary owned by the Company and its Subsidiaries shall
be irrevocably pledged to the Agent on behalf of the Banks, together with
certificates or other writings representing all shares of such stock or other
equity interest and for each such certificate an undated irrevocable stock power
or other similar instrument executed in blank with signatures guaranteed and
authenticated as the Agent may specify;

                  (b) cause such New Material Subsidiary to execute and deliver
to the Agent on behalf of the Banks an Election to Participate and a Note
payable to the order of each Bank that has requested Notes pursuant to Section
2.2(b), all of which shall be irrevocable;

                  (c) deliver or cause to be delivered to the Agent on behalf of
the Banks all agreements, documents, instruments and other writings described in
Sections 7.3(b), (c) and (f) with respect to such New Material Subsidiary; and

                  (d) deliver or cause to be delivered to the Agent on behalf of
the Banks all such information regarding the condition (financial or otherwise),
business and operations of such New Material Subsidiary as the Agent or any Bank
through the Agent may reasonably request.

Upon completion of the foregoing requirements, each such New Material Subsidiary
shall be an Obligor (and both Borrower and a Guarantor in accordance with
Article XI) for all purposes of this Agreement and the other Credit Documents.

         8.15 Change of Offices. If any Obligor or Obligated Subsidiary intends
to change the location of its sole principal place of business or chief
executive office, it shall give the Agent written notice of its new address no
later than one week before such event and shall furnish, if the Agent so
requests following its receipt of such notice, an executed financing statement
or other appropriate notice to be publicly filed in the jurisdiction in which
such new place of business or chief executive office is located.

         8.16 Obligors. The Company shall ensure that at all times the Persons
included as "Obligors" under this Agreement represent at least 90% of the
consolidated assets, net worth and Adjusted EBITDA of the Company and its
consolidated subsidiaries.

         8.17 Performance of Contracts. Each Obligor shall (a) perform and
observe, and shall cause each of its Subsidiaries to perform an observe, all the
terms and provisions to be performed or observed by it under each contract to
which it is party, (b) maintain each such contract in full force and effect
(except for termination of such a contract resulting from exercise of remedies
against a defaulting counterparty), and (c) enforce each such contract in
accordance with its terms, in each case above to the extent

                                       93
<PAGE>
that the failure to do any of the foregoing, individually or in the aggregate,
could reasonably be expected to result in a Material Adverse Effect.

Agent, the Issuing Bank, or any of them, to draw upon the issuer of such letter
of credit at any time without condition except the presentation of a written
certificate that such amounts have been drawn under a Letter of Credit; or pay
to the Agent in same day funds at the office of the Agent designated in such
demand, for deposit in the Cash Collateral Account, an amount equal to the
maximum amount available to be drawn under the Letters of Credit then
outstanding; and

                  (d)      the Agent may, in its sole discretion, without notice
to any Obligor except as required by law, and at any time and from time to time,
apply any proceeds of the Cash Collateral Account and all cash proceeds received
in respect of any sale of, collection from or other realization upon, all or any
part of the Cash Collateral Account in accordance with the Security Agreement;
and

                  (e)      subject to the Security Documents, the Agent shall,
at the request of, and may, with the consent of, the Required Banks, exercise
all rights and remedies available to it under the Security Documents or any
other agreement; and

                                      108
<PAGE>
                  (f)      each Bank may, to the fullest extent not prohibited
by applicable law, exercise its rights of offset against each account and all
other property of any Person liable on any of the Obligations in the possession
of such Bank, which right is hereby granted by each Obligor to the Banks; and

                  (g)      the Agent and each Bank may exercise any and all
other rights pursuant to the Credit Documents, at law and in equity;

provided, however, that, upon the occurrence of any event specified in Section
10.1(f) or (g) (in the case of Section 10.1(g), upon the expiration of the 60
day period mentioned therein), the obligation of each Bank to make Loans and to
issue Letters of Credit shall automatically terminate, and the unpaid principal
amount of all outstanding Loans, all interest accrued and unpaid thereon, all
fees and all other Obligations (including Reimbursement Obligations) shall
automatically become due and payable, all without any further act of the Agent
or any Bank.

         10.3     Cash Collateral Account. Each Obligor agrees that, in the
event the Commitments are terminated at any time, whether automatically or at
the option of the Agent and the Required Banks as provided in Section 10.2, such
Obligor shall either (a) promptly pay to the Agent an amount in immediately
available funds equal to 100% of its then aggregate amount of Letter of Credit
Obligations which remain outstanding, which funds shall be held by the Agent in
the Cash Collateral Account, or (b) promptly provide to the Agent a letter of
credit issued by an issuer acceptable to each of the Agent, the Issuing Bank and
the Required Banks in their respective sole discretion, in form and substance
satisfactory to the Agent, the Issuing Bank and the Required Banks in their sole
discretion, in an amount equal to 100% of the aggregate Letter of Credit
Obligations which remain outstanding, which letter of credit shall have an
expiry no earlier than 10 days after the expiry of the last Letter of Credit to
expire and shall permit the Agent, the Issuing Bank, or any of them, to draw
upon the issuer of such letter of credit at any time without condition except
the presentation of a written certificate that such amounts have been drawn
under a Letter of Credit.

         10.4     Preservation of Security for Contingent Obligations. In the
event that, following (a) the occurrence of an Event of Default and the exercise
of any rights available to the Agent under the Credit Documents, and (b) payment
in full of the principal amount then outstanding of and the accrued and unpaid
interest on the Loans and Reimbursement Obligations and all fees and all other
Obligations, any Letter of Credit shall remain outstanding and undrawn upon, the
Agent shall be entitled to hold (and each Obligor hereby assigns to the Agent on
behalf of the Banks and grants and conveys to the Agent a security interest in
and to) all cash or other property ("Proceeds of Remedies") realized or arising
out of the exercise by the Agent of any rights available to it under the Credit
Documents, at law or in equity, including the proceeds of any foreclosure, in
the Cash Collateral Account (subject to Section 3.5) as collateral for the
payment of any amounts due or to become due under or in respect of such Letters
of Credit; provided, that the aggregate amount so held shall not exceed 100% of
all Letter of Credit Obligations then outstanding. Such Proceeds of Remedies
shall be held for the ratable benefit of the Banks issuing such Letters of
Credit and Banks holding

                                      109
<PAGE>
participations therein. Such Proceeds of Remedies shall constitute "Collateral"
for all purposes under the terms and provisions of the Security Documents, and
the rights, titles, benefits, privileges, duties and obligations of the Agent
with respect thereto shall be governed by the terms and provisions of this
Agreement (including Section 3.5) and, to the extent not inconsistent with this
Agreement, the Security Documents. Notwithstanding anything herein to the
contrary, such Proceeds of Remedies shall be applied solely to Reimbursement
Obligations arising in respect of any such Letters of Credit and/or the payment
of any Bank's obligations under any such Letter of Credit when such Letter of
Credit is drawn upon. Each Obligor hereby agrees to execute and deliver to the
Agent and the Banks such security agreements, pledges or other documents as the
Agent or any of the Banks may, from time to time, require to create, perfect,
protect and realize upon the assignment, pledge, lien and security interest in
and to any such Proceeds of Remedies provided for in this Section 10.4. Upon the
payment or expiry of all Letter of Credit Obligations, all Proceeds of Remedies
shall be released to the Company in due form at the Company's cost.

         10.5     Rights Not Exclusive. The rights provided for in this
Agreement and the other Credit Documents are cumulative and are not exclusive of
any other rights, powers, privileges or remedies provided by law or in equity or
under any other instrument, document or agreement.

                                   ARTICLE XI
                                    GUARANTY

         11.1     Definitions. As used in this Article XI (sometimes in this
Article XI called this "Guaranty"), a "Guarantor" and the "Guarantors" means an
Obligor and the Obligors, respectively, and the following terms shall have the
following meanings:

         "Guaranteed Debt" means, as to any Guarantor, the Maximum Amount with
respect to such Guarantor less the amounts, if any, of payments of the
Guaranteed Debt made by such Guarantor and clearly identified as such in a
notice accepted in writing by the Agent confirming the payment and reduction of
the Guaranteed Debt as to such Guarantor.

         "Guarantor's Net Worth" means, as to any Guarantor, as of any date of
determination thereof: (a) the aggregate fair saleable value of the assets of
such Guarantor as of such date (including the fair saleable value of the amounts
received or receivable by such Guarantor pursuant to its rights to subrogation,
contribution and indemnity), minus (b) the amount of all liabilities of such
Guarantor, contingent or otherwise, as of such date (but excluding all
contingent liabilities under this Guaranty), minus (c) One Dollar ($1.00). It is
agreed that a Guarantor's Net Worth may fluctuate from time to time after the
date it becomes a Guarantor, as it is determined on each Determination Date (as
defined in the definition of "Maximum Amount").

         "Maximum Amount" means, with respect to any Guarantor except WGI, the
greater of (a) all proceeds (without duplication) of the Obligations directly or
indirectly (by intercompany loan, advance, capital contribution, such
Guarantor's ownership

                                      110
<PAGE>
interest in any Person receiving the proceeds of the Obligations, or otherwise)
advanced to or for the account of, or used by or for the benefit of, such
Guarantor; (b) ninety percent (90%) of such Guarantor's Net Worth from time to
time; or (c) the amount that in a legal proceeding brought within the applicable
limitations period is determined by the final, non-appealable order of a court
having jurisdiction over the issue and the applicable parties to be the amount
of value given by the Agent and the Banks, or received by such Guarantor, in
exchange for the obligations of such Guarantor under this Guaranty; provided,
however, that the Maximum Amount, with respect to any Guarantor, shall not
exceed the maximum amount which such Guarantor could pay or be liable for under
this Guaranty without having such payment or liability set aside as a fraudulent
conveyance or fraudulent transfer or other similar action under any applicable
bankruptcy, insolvency or other similar law of any jurisdiction. If on the date
of any Loan made or Letter of Credit issued after the date hereof (any such date
being herein called a "Determination Date"), ninety percent (90%) of such
Guarantor's Net Worth is greater than either of the amounts described in clauses
(a) and (c) above, the Maximum Amount shall be deemed to have increased through
and as of such Determination Date to ninety percent (90%) of such Guarantor's
Net Worth as determined on such Determination Date (and the Guaranteed Debt as
to such Guarantor shall have correspondingly increased), without further action
by or agreement between the Agent and such Guarantor, and any subsequent
reduction or diminution of such Guarantor's Net Worth after such Determination
Date will not reduce the Guaranteed Debt as to such Guarantor. Notwithstanding
anything to the contrary contained in this definition of "Maximum Amount" or in
any other provision of this Guaranty, but subject to the proviso in the first
sentence of this definition, "Maximum Amount" shall never be less than the
amount referred to in clause (a) above. The Banks and each Guarantor acknowledge
and agree that, for the purposes of this Guaranty and any legal proceeding
brought within the applicable limitations period before a court having
jurisdiction over the issue and the applicable parties, the amount of value
given by the Agent and the Banks in connection with the Obligations is presumed
to be equal to, without duplication, all funds, all matured and contingent
obligations assumed by Agent and/or the Banks (e.g., Letter of Credit
Obligations), property, and proceeds that are directly or indirectly (e.g., by
intercompany loan, advance, capital contribution, such Guarantor's ownership
interest in any Person receiving the proceeds of the Obligations, or otherwise)
advanced to or for the account of, or used by or for the benefit of, such
Guarantor in connection with the transactions and events relating to the
Obligations.

         11.2     Guaranty.

                  (a)      In order to induce the Banks and the Agent to execute
and deliver this Agreement and the other Credit Documents, to make or maintain
the Loans and to issue and maintain the Letters of Credit, and in consideration
thereof, each Guarantor, as a primary obligor and not as a surety,
unconditionally, jointly and severally, guarantees to the Agent and the Banks
the full, prompt and punctual payment and performance of the Obligations of each
other Borrower when due (whether at stated maturity, by acceleration or
otherwise) in accordance with the Credit Documents. This Guaranty is
irrevocable, unconditional and absolute, and if for any reason all or any
portion of the Obligations shall not be paid when due, Guarantors, jointly and
severally, agree immediately to pay

                                      111
<PAGE>
the Obligations to the Agent or other Person entitled to them, in Dollars,
regardless of (i) any defense, right of set-off or counterclaim which any
Guarantor may have or assert which would otherwise discharge a guarantor under
applicable law, (ii) whether the Agent or any other such Person shall have taken
any steps to enforce any rights against any Borrower, any other Guarantor or any
other Person to collect any of the Obligations, and (iii) any other
circumstance, condition or contingency (other than a defense of full and timely
payment or performance of the Obligations) which constitutes, or might be
construed to constitute, an equitable or legal discharge of any Obligor for any
of the Obligations, or of such Guarantor under the guarantee contained in this
Article XI, in bankruptcy or in any other instance.

                  (b)      NOTWITHSTANDING THE FOREGOING, to the extent that in
a legal proceeding brought within the applicable limitations period it is
determined by the final, non-appealable order of a court having jurisdiction
over the issue and the applicable parties that any Guarantor (except WGI)
received less than a reasonably equivalent value in exchange for such
Guarantor's incurrence of its obligations under this Guaranty, then and only
then the liability of such Guarantor for all Obligations shall be limited in
amount to the Guaranteed Debt of such Guarantor. The foregoing limitation as it
applies to a particular Guarantor shall not affect or excuse the liability or
obligations of any other Guarantor, nor may it be raised as a defense to any
action or claim against such other Guarantor. The Agent shall have the right to
determine and designate from time to time, without notice to or assent of any
Guarantor, which portions of the Obligations such limitation applies to, and
each Guarantor acknowledges that such determination and designation shall be
conclusive on all parties. This Guaranty shall not fail or be ineffective or
invalid or be considered too indefinite or contingent with respect to any
Guarantor because the Guaranteed Debt applicable to such Guarantor may fluctuate
from time to time or for any other reason. The guarantee contained in this
Article XI, subject to Section 11.10, shall remain in full force and effect
until the time provided in Section 11.8 (except for any obligations expressly
stated to survive such termination), notwithstanding that from time to time
prior thereto any Obligor may be free from any Obligations.

         11.3     Application. Each Guarantor agrees that any payment or
prepayment by a Guarantor or any other Person against the Obligations (other
than payments made by a Guarantor in accordance with the procedures described in
the definition of "Guaranteed Debt" and then only with respect to such
Guarantor's liability under this Guaranty) shall be deemed paid first against
that portion of the Obligations not included in "Guaranteed Debt" or determined
for any reason not to be a part of "Guaranteed Debt," and then shall be paid
against any portion of the Obligations that is Guaranteed Debt, in such order
and manner as the Agent shall determine in its sole discretion. Article V of
this Agreement, including Sections 5.6 and 5.9, shall apply to all payments by
Guarantors under this Article XI. Any payment by any Guarantor under this
Article XI shall reduce pro tanto any intercompany obligation of such Guarantor
to the other Obligors.

         11.4     Notification. Each Guarantor agrees that whenever, at any
time, or from time to time, it shall make any payment to the Agent on account of
its liability under this Article XI, it will notify the Agent in writing that
such payment is made under the

                                      112
<PAGE>
guarantee contained in this Article XI. No payment or payments made by any
Obligor or any other Person or received or collected by the Agent or any Bank
from any Obligor or any other Person by virtue of any action or proceeding or
any setoff or appropriation or application, at any time or from time to time, in
reduction of or in payment of the Obligations shall be deemed to modify, reduce,
release or otherwise affect the liability of any Guarantor under this Article XI
which, notwithstanding any such payment or payments, shall remain liable for the
unpaid and outstanding Obligations until, subject to Section 11.10, the
Obligations are paid in full and the Commitments are terminated.

         11.5     Amendments, etc. with respect to the Obligations. Each
Guarantor shall remain obligated under this Article XI notwithstanding that,
without any reservation of rights against such Guarantor, and without notice to
or further assent by such Guarantor, (a) any demand for payment of or reduction
in the principal amount of any of the Obligations made by the Agent or any Bank
through the Agent is rescinded by the Agent or such Bank, (b) any of the
Obligations is continued, (c) any of the Obligations, or the liability of any
other party upon or for any part thereof, or any collateral security or
guarantee therefor or right of offset with respect thereto, is, from time to
time, in whole or in part, renewed, extended, amended, modified, accelerated,
compromised, waived, surrendered or released by the Agent or any Bank. This
Agreement and any other Credit Documents may from time to time be amended,
modified, supplemented or terminated, in whole or in part, in accordance with
their terms, and any collateral security, guarantee or right of offset at any
time held by the Agent or any Bank for the payment of the Obligations may be
sold, exchanged, waived, surrendered or released, all without in any way
releasing, diminishing, reducing, impairing or otherwise affecting the
obligations of each Guarantor under this Article XI. Neither the Agent nor any
Bank shall have any obligation to protect, secure, perfect or insure any Lien at
any time held by it as security for the Obligations or for the guarantees
contained in this Article XI or any property subject thereto. Specific written
agreements among the Banks, the Issuing Bank and the Agent, or any of them, on
the one hand, and any one or more of the Obligors, on the other hand, made in
accordance with this Agreement and the other Credit Documents and entered into
prior to Default, shall not discharge any Guarantor or release, diminish,
reduce, impair or otherwise affect the obligations of any Guarantor under this
Article XI, except that such agreements shall, insofar and only insofar as the
Obligations of one or more Obligors are changed thereby, change to that extent
and to that extent only the obligations of the Guarantors in their capacity as
guarantors of such Obligations.

Each Guarantor waives diligence, presentment, protest, demand for payment and
notice of default or nonpayment to or upon such Guarantor or any other Obligor
with respect to the Obligations. The guarantee contained in this Article XI
shall be construed as a continuing, absolute and unconditional guarantee of
payment without regard to (a) the validity or enforceability of this Agreement
or any other Credit Document, any of the Obligations or any collateral security
therefor or any guarantee or right of offset with respect thereto at any time or
from time to time held or purported to be held by the Agent or any Bank, (b) the
legality under applicable Legal Requirements of repayment by the relevant
Obligor of any of the Obligations or the adoption of any Legal Requirement
purporting to render any such Obligations of a Obligor null and void, (c) any
defense, setoff or counterclaim (other than a defense of payment or performance
by the applicable

                                      113
<PAGE>
Obligor) which may at any time be available to or be asserted by such Guarantor
against the Agent or any Bank, or (d) any other circumstance whatsoever (with or
without notice to or knowledge of such Guarantor or any Obligor) (other than a
defense of full payment and performance of all of the Obligations) which
constitutes, or might be construed to constitute, an equitable or legal
discharge of any Obligor for any of the Obligations, or of such Guarantor under
the guarantee contained in this Article XI, in bankruptcy or in any other
instance. The Agent or any Bank may, but shall be under no obligation to, pursue
such rights and remedies as it may have against any Obligor or any other
Guarantor or any other Person or against any collateral security or guarantee
for the Obligations or any right of offset with respect thereto, and any failure
by the Agent or any Bank to pursue such other rights or remedies or to collect
any payments from any Obligor or any other Guarantor or any such other Person or
to realize upon any such collateral security or guarantee or to exercise any
such right of offset, or any release of any Obligor or any other Guarantor or
any such other Person or of any such collateral security, guarantee or right of
offset, shall not relieve any Guarantor of any liability under this Article XI
and shall not impair or affect the rights and remedies, whether express, implied
or available as a matter of law, of the Agent or any Bank against any Guarantor.

         11.6     No Release. Each Guarantor's covenants, agreements and
obligations under this Article XI shall in no way be released, diminished,
reduced, impaired or otherwise affected by reason of the happening from time to
time of any of the following things, for any reason, whether by voluntary act,
operation of law or order of any competent Governmental Authority and whether or
not such Guarantor is given any notice or is asked for or gives any further
consent (all requirements for which, however arising, each Guarantor hereby
WAIVES):

                  (a)      voluntary or involuntary liquidation, dissolution,
sale of any collateral, marshaling of assets and liabilities, change in
corporate or organizational status, receivership, insolvency, bankruptcy,
assignment for the benefit of creditors, reorganization, arrangement,
composition or readjustment of debt or other similar proceedings of or affecting
any Obligor or any other Guarantor or any of the assets of any Obligor or any
other Guarantor, even if any of the Obligations is thereby rendered void,
unenforceable or uncollectible.

                  (b)      occurrence or discovery of any lack of genuineness,
irregularity, invalidity or unenforceability of any of the Obligations or Credit
Documents or any defect or deficiency in any of the Obligations or Credit
Documents.

                  (c)      failure by any Bank, the Agent or any other Person to
notify--or timely notify--any Guarantor of any default, event of default or
similar event (however denominated) under any of the Credit Documents, or of any
other action taken or not taken by any Bank or the Agent against any Obligor,
any other Guarantor or any other Person, or any other event or circumstance.
Neither the Agent nor any Bank shall have any duty or obligation to give any
Guarantor any notice of any kind under any circumstances whatsoever with respect
to or in connection with this Guaranty.

                                      114
<PAGE>
                  (d)      occurrence of any event or circumstance which might
otherwise constitute a defense available to, or a discharge of, any Obligor or
any other Guarantor (other than a defense of full payment and performance),
including failure of consideration, fraud by or affecting any Person, usury,
forgery, breach of warranty, failure to satisfy any requirement of the statute
of frauds, running of any statute of limitation, accord and satisfaction and any
defense based on election of remedies of any type.

                  (e)      receipt and/or application of any proceeds, credits
or recoveries from any source, including any proceeds, credits, or amounts
realized from exercise of any rights, remedies, powers or privileges of any Bank
or the Agent under the Credit Documents, by law or otherwise available to any
Bank or the Agent (other than an application which results in full payment and
performance of all Obligations).

         11.7     Waivers. Each Guarantor hereby WAIVES and RELEASES all right
to require marshalling of assets and liabilities, sale in inverse order of
alienation, notice of acceptance of this Guaranty and of any liability to which
it applies or may apply, notice of the creation, accrual, renewal, increase,
extension, modification, amendment or rearrangement of any part of the
Obligations, presentment, demand for payment, protest, notice of nonpayment,
notice of dishonor, notice of intent to accelerate, notice of acceleration and
all other notices and demands, collection suit and the taking of any other
action by any Bank or the Agent.

         11.8     Guaranty of Payment and Not of Collection. This is an absolute
guaranty of payment and not of collection, and an absolute guaranty of
performance of all of the obligations of each Obligor under the Credit
Documents, and each Guarantor WAIVES any right to require that any action be
brought against any Obligor, any other Guarantor or any other Person, or that
any Bank or the Agent be required to enforce, attempt to enforce or exhaust any
rights, benefits or privileges of any Bank or the Agent under any of the Credit
Documents, by law or otherwise; provided that nothing herein shall be construed
to prevent any Bank or the Agent from exercising and enforcing at any time any
right, benefit or privilege which any Bank or the Agent may have under any
Credit Document or by law from time to time, and at any time, and each Guarantor
agrees that each Guarantor's obligations hereunder are--and shall be--absolute,
independent, unconditional, joint and several under any and all circumstances.
Should any Bank or the Agent seek to enforce any Guarantor's obligations by
action in any court, each Guarantor WAIVES any requirement, substantive or
procedural, that (a) the Agent pursue any foreclosure action, realize or attempt
to realize on any security (including the Cash Collateral Account) or preserve
or enforce any deficiency claim against any Obligor, any other Guarantor or any
other Person after any such realization, (b) a judgment first be sought or
rendered against any Obligor, any other Guarantor or any other Person, (c) any
Obligor, any other Guarantor or any other Person be joined in such action or (d)
a separate action be brought against any Obligor, any other Guarantor or any
other Person. Each Guarantor's obligations under this Guaranty are several from
those of any other Obligor or any other Person, and are primary obligations
concerning which such Guarantor is the principal obligor. All waivers in this
Agreement or any of the other Credit Documents shall be without prejudice to the
right of any Bank or the Agent at its option to proceed against any Obligor, any
other Guarantor or any other Person, whether

                                      115
<PAGE>
by separate action or by joinder. Each Guarantor agrees that this Guaranty shall
not be discharged except by payment of the Obligations in full, expiration of
all Letters of Credit, complete performance of all obligations of each Obligor
under the Credit Documents and termination of each Bank's obligation--if any--to
make any further advances or extend other financial accommodations to any
Obligor under the Credit Documents.

         11.9     Obligations Joint and Several with Other Guaranties. If any
other Person makes any guaranty of any of the obligations guaranteed hereby or
gives any security for them, each Guarantor's obligations under this Article XI
shall be joint and several with the obligations of such other Person pursuant to
such agreement or other papers making the guaranty or giving the security.

         11.10    Reinstatement. Each Guarantor agrees that, if at any time all
or any part of any payment previously applied by the Agent or any Bank to the
Obligations is or must be returned by any Bank or the Agent--or recovered from
any Bank or the Agent--for any reason (including the order of any bankruptcy
court), this Guaranty shall automatically be reinstated to the same effect as if
the prior application had not been made, and, in addition, each Guarantor hereby
agrees to indemnify each Bank and the Agent against, and to save and hold each
Bank and the Agent harmless from, any required return by any Bank or the
Agent--or recovery from any Bank or the Agent--of any such payment because of
its being deemed preferential under applicable bankruptcy, receivership or
insolvency laws, or for any other reason. The provisions of this Section 11.10
shall survive the termination of this Guaranty and any satisfaction and
discharge of any Obligor by virtue of any payment, court order or other Legal
Requirement.

         11.11    Representations and Warranties. Each Guarantor warrants and
represents as follows: It has determined that its liability and obligation under
this Guaranty may reasonably be expected to substantially benefit it directly or
indirectly, and its board of directors (or such board's duly authorized and
appointed designee) or other equivalent body has made that determination. Each
Guarantor is closely related legally and economically to every other Guarantor,
each deriving benefits from the other. The maintenance and improvement of each
Guarantor's financial condition is vital to sustaining each other Guarantor's
business, and the transactions contemplated in this Agreement produce distinct
and identifiable financial and economic direct or indirect benefits to each
Guarantor. Such identifiable benefits include: (a) the availability to each
Borrower of the proceeds of the Loans on an as-needed basis either directly or
indirectly by way of intercompany loans and/or capital contributions for general
corporate or other purposes and (b) the general improvement of each Guarantor's
financial and economic condition. Each Guarantor has had full and complete
access to the underlying papers relating to the Obligations and all other papers
executed by any Obligor or any other Person in connection with the Obligations,
has reviewed them and is fully aware of the meaning and effect of their
contents. Such Guarantor is fully informed of all circumstances which bear upon
the risks of executing this Guaranty and which a diligent inquiry would reveal.
Each Guarantor has adequate means to obtain from the other Obligors on a
continuing basis information concerning such Obligors' financial condition, and
is not depending on the Agent or any Bank to provide such information,

                                      116
<PAGE>
now or in the future. Each Guarantor agrees that neither the Agent nor any Bank
shall have an obligation to advise or notify it or to provide it with any data
or information. Such Guarantor is Solvent and will not be rendered not Solvent
by virtue of its execution and delivery of this Agreement and the other Credit
Documents.

         11.12    Joinder of Additional Subsidiaries. It is contemplated by each
Guarantor that additional Subsidiaries of the Company may from time to time
become Guarantors hereunder (as required by the terms of this Agreement,
including Sections 7.3 and 8.14)) and a party to this Agreement, by their
execution and delivery to the Agent on behalf of the Banks of an Election to
Participate. Each Guarantor agrees, consents and acknowledges that upon the
execution and delivery to the Agent by any such Designated Subsidiary of an
Election to Participate, such Designated Subsidiary shall become a Guarantor
hereunder for all purposes, jointly and severally liable hereunder (to the
extent and subject to the limitations set forth in this Guaranty) as if such
Designated Subsidiary had originally been a party to this Guaranty, without
notice to any Guarantor or any other Person. Delivery of an Election to
Participate to any Guarantor or any other Person is not required for the
Designated Subsidiary executing and delivering such Election to Participate to
become a Guarantor hereunder and a party to this Agreement.

         11.13    Acknowledgement. Each Guarantor agrees that the Obligations
guaranteed by such Guarantor under this Guaranty may at any time and from time
to time exceed such Guarantor's Maximum Amount without impairing this Guaranty
or affecting the rights and remedies of the Agent or the Banks under this
Guaranty.

         11.14    Primary Obligations. The obligations of each Guarantor under
this Guaranty are those of a primary obligor, and not merely a surety, and are
independent of the obligations of each other Guarantor. A separate action or
actions may be brought against any Guarantor whether or not an action is brought
against any other Guarantor or other obligor in respect of the Obligations or
whether any other Guarantor or any other obligor in respect of the Obligations
is joined in any such action or actions.

         11.15    Effect of Stay. If an event permitting the acceleration of any
of the Obligations shall at any time have occurred and be continuing and such
acceleration shall at such time be prevented by reason of the pendency against
one or more of the Obligors of a case or proceeding under any bankruptcy or
insolvency law, each Guarantor agrees that, for purposes of this Guaranty and
its obligations hereunder, the Obligations shall be deemed to have been
accelerated and such Guarantor shall forthwith pay such Obligations (including
interest which but for the filing of such petition in bankruptcy would accrue on
such Obligations), and the other obligations hereunder, without any further
notice or demand.

         11.16    Waiver of Diligence, Etc. To the extent permitted by
applicable law, each Guarantor hereby WAIVES promptness, diligence, notice of
acceptance and any and all other notices with respect to any of the Obligations
and this Guaranty and any requirement that the Agent or any Bank protect,
secure, perfect or insure any security interest in or any Lien on any property
subject thereto or exhaust any right to take any action against any Obligor or
any other Person or any collateral or security or any balance

                                      117
<PAGE>
of any deposit account or credit on the books of any Bank in favor of any
Obligor or any other Guarantor.

         11.17    Subrogation. Each Guarantor expressly WAIVES any and all
rights of subrogation, reimbursement, contribution, exoneration and indemnity,
contractual, statutory or otherwise, against the Agent and the Banks
individually and collectively, including any claim or right of subrogation under
the Bankruptcy Code (Title 11 of the U.S. Code) or any successor or similar
Legal Requirement arising from the existence or performance of this Guaranty,
until the termination of this Article XI in accordance with Section 11.8, and
until such termination each Guarantor irrevocably WAIVES any right to enforce
any remedy which the Agent and the Banks or any one or more of them now have or
may hereafter have against any Obligor or any other Guarantor and the benefit of
and any right to participate in any security now or hereafter held by the Agent
or the Banks or any one or more of them. Until such termination, if any amount
shall be paid by or on behalf of any Obligor or any other Person to any
Guarantor on account of any of the rights waived in this Section 11.17, such
amount shall be held by such Guarantor in trust, segregated from other funds of
such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned
over to the Agent in the exact form received by such Guarantor (duly indorsed by
such Guarantor to the Agent, if required), to be applied against the
Obligations, whether matured or unmatured, in such order as the Agent may
determine. The provisions of this Section 11.17 shall survive the term of the
guarantee contained in this Article XI, the payment in full of the Obligations
and the termination of the Commitments.

         11.18    Administrative Matters. If, in the exercise of any of its
rights and remedies, the Agent or any Bank shall forfeit any of its rights or
remedies, including its right to enter a deficiency judgment against any Obligor
or any other Guarantor, for any reason, each Guarantor hereby consents to such
action, even if such action by the Agent or such Bank shall result in a full or
partial loss of any rights of subrogation which such Guarantor might otherwise
have had but for such action by the Agent or such Bank. Any election of remedies
which results in the denial or impairment of the right of the Agent or such Bank
to seek a deficiency judgment against any Obligor or any other Guarantor shall
not impair such Guarantor's obligation to pay the full amount of the
Obligations. In the event the Agent or any Bank shall bid at any foreclosure or
trustee's sale or at any private sale permitted by law or under the Credit
Documents, the Agent or such Bank may bid all or less than the amount of the
Obligations and the amount of such bid need not be paid by the Agent or such
Bank but shall be credited against the Obligations. The amount of the successful
bid at any such sale, whether the Agent or such Bank or any other party is the
successful bidder, shall be conclusively deemed to be the fair market value of
the Collateral and the difference between such bid amount and the remaining
balance of the Obligations shall be conclusively deemed to be the amount of the
Obligations guaranteed under this Guaranty, notwithstanding that any present or
future law or court decision or ruling may have the effect of reducing the
amount of any deficiency claim to which the Agent or any Bank might otherwise be
entitled but for such bidding at any such sale.

                                      118
<PAGE>
         11.19    Survival; Persons Bound. The obligation of each Guarantor
under this Guaranty is a continuing guaranty and shall (a) remain in full force
and effect until payment in full (after the termination of the Commitments and
expiration of all outstanding Letters of Credit) of the Obligations and all
other amounts payable under this Guaranty; (b) be binding upon such Guarantor,
its successors and assigns; and (c) inure, together with the rights and remedies
of the Agent and the Banks under this Guaranty, to the benefit of the Agent, the
Banks and their respective successors, transferees and assigns. Without limiting
the generality of the foregoing, the Agent or any Bank may assign or otherwise
transfer its rights and obligations under this Agreement and the other Credit
Documents to any other Person or entity, and such other Person or entity shall
thereupon become vested with all the benefits in respect thereof granted to the
Agent or any Bank in this Guaranty or otherwise, all as provided in, and to the
extent set forth in, Section 13.7.

         11.20    Indemnification. The Guarantors agree that while their
respective obligations to the Agent and the Banks under this Agreement and the
other Credit Documents are joint and several as to the Banks and the Agent
(subject to the limits expressed therein), each Guarantor shall be liable as
among other Guarantors with respect to any particular Loan, Reimbursement
Obligation or other portion of the Obligations only for its Proportionate Share
(as hereinafter defined) of such Loan, Reimbursement Obligation or other portion
of the Obligations calculated as of the time such Loan, Reimbursement Obligation
or other portion of the Obligations was incurred. If at any time any Guarantor
(the "Indemnified Guarantor") makes any payment to the Agent or any of the Banks
or otherwise pays any amount (collectively, the "Indemnified Outlay") with
respect to any such Loan, Reimbursement Obligation or other particular portion
of the Obligations by virtue of any demand therefor pursuant to the Guaranty or
otherwise pursuant to the exercise by Agent or any Bank of their respective
other rights under the Credit Documents, the Indemnified Guarantor shall have
the right to make demand on any or all of the other Guarantors (each an
"Indemnifying Guarantor") for the payment to the Indemnified Guarantor of the
amount (the "Excess Amount") by which the Indemnified Outlay exceeds the
Indemnified Guarantor's Proportionate Share of the Indemnified Outlay and
thereupon the Indemnifying Guarantors upon which demand has so been made shall
pay to the Indemnified Guarantor the Excess Amount; provided, that no
Indemnifying Guarantor shall be liable to pay to Indemnified Guarantor more than
the Indemnifying Guarantor's Proportionate Share of the Excess Amount; and
further provided, that payment to the Agent or any Bank by an Indemnified
Guarantor shall not give rise to any right by way of subrogation in favor of the
Indemnified Guarantor to any of the Banks' or the Agents' rights against any
Indemnifying Guarantor with respect to such payment. The term "Proportionate
Share" at any time shall mean with respect to any Guarantor the percentage
derived by dividing (a) such Guarantor's Net Worth of such Guarantor by (b) the
consolidated Guarantor's Net Worth of all Guarantors, all as of such time.

         11.21    Intent of the Parties. It is not the intention of the Parties
that this Article XI have any effect whatsoever on the rights or defenses of any
Guarantor in its capacity as a Borrower (as opposed to a Guarantor). In no event
shall this Article XI be interpreted in any manner such that any Guarantor's
rights or defenses in its capacity as a

                                      119
<PAGE>
Borrower (as opposed to a Guarantor) under this Agreement or applicable law are
in any way reduced, restricted, limited or otherwise diminished.

                                  ARTICLE XII
                                AGENCY PROVISIONS

         12.1     Appointment and Authorization of Agent. Each Bank hereby
irrevocably appoints, designates and authorizes the Agent to take such action on
its behalf under the provisions of this Agreement and each other Credit Document
and to exercise such powers and perform such duties as are expressly delegated
to it by the terms of this Agreement or any other Credit Document, together with
such powers as are reasonably incidental thereto. As used in this Article XII,
Agent shall include reference to its Affiliates and its own and its Affiliates'
officers, directors, employees and agents. Notwithstanding any provision to the
contrary contained elsewhere in this Agreement or in any other Credit Document,
the Agent shall not have any duties or responsibilities, except those expressly
set forth herein, or any fiduciary or trustee relationship with any Bank, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Credit Document or
otherwise exist against the Agent.

         12.2     Delegation of Duties of Agent. The Agent may execute any of
its duties under this Agreement or any other Credit Document by or through
agents, employees or attorneys-in-fact and shall be entitled to advice of
counsel concerning all matters pertaining to such duties. The Agent shall not be
responsible for the negligence or misconduct of any agent or attorney-in-fact
that it selects with reasonable care. Without in any way limiting any of the
foregoing (or imposing any liability upon the Agent), each Bank acknowledges
that the Agent shall have no greater responsibility in the operation of the
Letters of Credit than is specified in the UCP or ISP 98.

         12.3     Liability of Agent. Neither the Agent nor any of its officers,
directors, employees, agents, attorneys-in-fact or Affiliates shall be (i)
liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Credit Document (except for its own
gross negligence or willful misconduct) or (ii) responsible in any manner to any
of the Banks for any recital, statement, representation or warranty made by any
Obligor or Obligated Subsidiary or any officer thereof contained in this
Agreement or in any other Credit Document or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Agent under or in connection with, this Agreement or any other Credit Document
or for the value of any Collateral or the validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Credit Document or
for any failure of any Obligor or Obligated Subsidiary or any other party to any
Credit Document to perform its obligations hereunder or thereunder. The Agent
shall not be under any obligation to any Bank to ascertain or to inquire as to
the observance or performance of any of the agreements contained in, or
conditions of, this Agreement or any other Credit Document, or to inspect the
properties, books or records of the Company or any of its Subsidiaries.

                                      120
<PAGE>
         12.4     Reliance by Agent.

                  (a)      The Agent shall be entitled to rely, and shall be
fully protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, telecopy, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel (including counsel to any
Obligor), independent accountants and other experts selected by the Agent. The
Agent shall be fully justified in failing or refusing to take any action under
this Agreement or any other Credit Document unless it shall first receive such
advice or concurrence of the Required Banks as it deems appropriate and, if it
so requests, it shall first be indemnified to its satisfaction by the Banks
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Agent shall in all cases be
fully protected in acting, or in refraining from acting, under this Agreement or
any other Credit Document in accordance with a request or consent of the
Required Banks (or such other number of Banks as shall be required under the
terms of the Credit Documents) and such request and any action taken or failure
to act pursuant thereto shall be binding upon all of the Banks and all future
holders of the Loans and the other Obligations. Regarding any enforcement,
litigation or collection proceedings hereunder or under any Credit Document, the
Agent shall in all cases be fully justified in failing or refusing to act under
the Credit Documents unless it shall have received further assurances to its
satisfaction by the Banks of their indemnification obligations under Section
12.7 against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action.

                  (b)      For purposes of determining compliance with the
conditions specified in Sections 7.1, 7.2 and 7.3, each Bank shall be deemed to
have consented to, approved or accepted or to be satisfied with each document or
other matter required thereunder to be consented to or approved by or acceptable
or satisfactory to the Banks unless an officer of the Agent responsible for the
transactions contemplated by the Credit Documents shall have received actual
notice from the Bank prior to the initial Borrowing specifying its objection
thereto and either such objection shall not have been withdrawn by notice to the
Agent to that effect or the Bank shall not have made available to the Agent the
Bank's ratable portion of such Borrowing.

         12.5     Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default, except
with respect to defaults in the payment of principal, interest and fees due to
the Agent for the account of the Banks, unless the Agent shall have received
written notice from a Bank or the Company or any Obligor referring to this
Agreement, describing such Default or Event of Default and stating that such
notice is a "notice of default". In the event that the Agent receives such a
notice, the Agent shall give prompt notice thereof to the Banks. The Agent shall
take such action with respect to such Default or Event of Default as shall be
requested by the Required Banks in accordance with Article XII; provided,
however, that unless and until the Agent shall have received any such request,
the Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to

                                      121
<PAGE>
such Default or Event of Default as it shall deem advisable in the best
interests of the Banks, and shall be fully protected under Section 12.7 for such
action or inaction.

         12.6     Credit Decision. Each Bank expressly acknowledges that neither
the Agent nor any of its affiliates nor any officer, director, employee, agent,
attorney-in-fact of any of them has made any representation or warranty to it
and that no act by the Agent, the Syndication Agent, the Joint Book Runners, the
Lead Arranger or the Joint Lead Arranger hereafter taken, including any review
of the affairs of the Company and its Subsidiaries or any Obligor shall be
deemed to constitute any representation or warranty by any of the Agent, the
Syndication Agent, the Joint Book Runners, the Lead Arranger or the Joint Lead
Arranger to any Bank. Each Bank represents to the Agent, the Syndication Agent,
the Joint Book Runners, the Lead Arranger and the Joint Lead Arranger that it
has, independently and without reliance upon the Agent, the Syndication Agent,
the Joint Book Runners, the Lead Arranger or the Joint Lead Arranger, and based
on such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, prospects, operations,
property, financial and other condition and creditworthiness of the Company and
its Subsidiaries and made its own decision to enter into this Agreement and
extend credit to the Obligors. Each Bank also represents that it will,
independently and without reliance upon the Agent, the Syndication Agent, the
Joint Book Runners, the Lead Arranger or the Joint Lead Arranger, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Credit Documents, and to
make such investigations as it deems necessary to inform itself as to the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Company and its Subsidiaries or any Obligor. Except for
notices, reports and other documents expressly required to be furnished to the
Banks by the Agent hereunder, none of the Agent, the Syndication Agent, the
Joint Book Runners, the Lead Arranger or the Joint Lead Arranger shall not have
any duty or responsibility to provide any Bank with any credit or other
information concerning the business, prospects, operations, property, financial
and other condition or creditworthiness of the Company and its Subsidiaries or
any Obligor which may come into the possession of the Agent, the Syndication
Agent, the Joint Book Runners, the Lead Arranger or the Joint Lead Arranger, or
any of their respective officers, directors, employees, agents,
attorneys-in-fact or Affiliates.

         12.7     INDEMNIFICATION BY BANKS. THE BANKS AGREE TO INDEMNIFY THE
AGENT, THE SYNDICATION AGENT, EACH JOINT BOOK RUNNER, THE LEAD ARRANGER, AND THE
JOINT LEAD ARRANGER (TO THE EXTENT NOT REIMBURSED BY OR ON BEHALF OF AN OBLIGOR
AND WITHOUT LIMITING THE OBLIGATION OF THE OBLIGORS TO DO SO), RATABLY ACCORDING
TO THEIR PERCENTAGE SHARES, FROM AND AGAINST ANY AND ALL LIABILITIES,
OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS,
EXPENSES AND DISBURSEMENTS OF ANY KIND WHATSOEVER WHICH MAY AT ANY TIME
(INCLUDING AT ANY TIME FOLLOWING THE REPAYMENT OF THE LOANS) BE IMPOSED ON,
INCURRED BY OR ASSERTED AGAINST THE AGENT, THE SYNDICATION AGENT, EACH JOINT
BOOK RUNNER, THE LEAD ARRANGER,

                                      122
<PAGE>
OR THE JOINT LEAD ARRANGER IN ANY WAY RELATING TO OR ARISING OUT OF THIS
AGREEMENT OR ANY OTHER CREDIT DOCUMENT OR ANY DOCUMENT CONTEMPLATED BY OR
REFERRED TO HEREIN OR THEREIN OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY
OR ANY ACTION TAKEN OR OMITTED BY THE AGENT UNDER OR IN CONNECTION WITH ANY OF
THE FOREGOING; WHETHER OR NOT ANY OF THE FOREGOING SPECIFIED IN THIS SECTION
12.7 ARISES FROM THE SOLE OR CONCURRENT NEGLIGENCE OF THE AGENT, THE SYNDICATION
AGENT, ANY JOINT BOOK RUNNER, THE LEAD ARRANGER OR THE JOINT LEAD ARRANGER,
PROVIDED, HOWEVER, THAT NO BANK SHALL BE LIABLE FOR THE PAYMENT TO THE AGENT OF
ANY PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES,
ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING FROM THE
AGENT'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. WITHOUT LIMITATION OF THE
FOREGOING, EACH BANK SHALL REIMBURSE THE AGENT PROMPTLY UPON DEMAND FOR ITS
RATABLE SHARE OF ANY COSTS OR OUT-OF-POCKET EXPENSES (INCLUDING FEES AND
EXPENSES OF COUNSEL AND THE ALLOCATED COST OF IN-HOUSE COUNSEL) INCURRED BY THE
AGENT IN CONNECTION WITH THE PREPARATION, EXECUTION, DELIVERY, ADMINISTRATION,
MODIFICATION, AMENDMENT OR ENFORCEMENT (WHETHER THROUGH NEGOTIATIONS, LEGAL
PROCEEDINGS OR OTHERWISE) OF, OR LEGAL ADVICE IN RESPECT OF RIGHTS OR
RESPONSIBILITIES UNDER, THIS AGREEMENT, ANY OTHER CREDIT DOCUMENT, OR ANY
DOCUMENT CONTEMPLATED BY OR REFERRED TO IN THIS AGREEMENT OR ANY OTHER CREDIT
DOCUMENT TO THE EXTENT THAT THE AGENT IS NOT REIMBURSED FOR SUCH EXPENSES BY OR
ON BEHALF OF ANY OBLIGOR. IF THE ISSUE OF THE OBLIGORS' LIABILITY HAS NOT YET
BEEN RESOLVED, OR IS IN DISPUTE, OR IF SUCH LIABILITY HAS NOT YET BEEN
SATISFIED, EACH BANK SHALL NONETHELESS ADVANCE TO THE AGENT (AS SECURITY FOR
SUCH BANK'S OBLIGATIONS PURSUANT TO THIS SECTION 12.7, AND NOT IN PAYMENT OF ITS
OBLIGATION) ON DEMAND ITS PERCENTAGE SHARE OF ANY FUNDS OWED BY THE OBLIGORS
AND/OR REQUIRED TO BE ADVANCED BY THE BANKS BY THE TERMS OF THIS SECTION 12.7
WERE THE QUESTION OF THE OBLIGORS' LIABILITY TO BE RESOLVED AGAINST THE AGENT
AND THE BANKS; PROVIDED, HOWEVER, THAT ANY FUNDS SO ADVANCED BY A BANK SHALL BE
RETURNED TO IT, WITHOUT INTEREST, WHEN, IF AND TO THE EXTENT THAT THE OBLIGORS
MAKE ANY REQUIRED REIMBURSEMENT TO AGENT. THE OBLIGATIONS OF THE BANKS UNDER
THIS SECTION 12.7 SHALL SURVIVE THE TERMINATION OF THIS AGREEMENT.

         12.8     Individual Capacity. Each of CLNY (and any successor acting as
Agent) and Canadian Imperial (and any successor acting as Syndication Agent) and
their respective Affiliates may make loans to, issue letters of credit for the
account of, accept deposits from and generally engage in any kind of business
with the Company and its Subsidiaries as though CLNY and Canadian Imperial were
not the Agent and the

                                      123
<PAGE>
Syndication Agent, respectively, under this Agreement and the other Credit
Documents, and each of them may accept fees and other consideration from the
Company, any other Obligor or their Affiliates (in addition to the fees
heretofore agreed to between the Company and the Agent and its Affiliates) for
services in connection with this Agreement or otherwise, all without having to
account for the same to the Banks. With respect to its Loans and any Letters of
Credit issued by it, each of CLNY and CIBC Inc. (and any of their successors
acting as Agent and Syndication Agent) shall have the same rights and powers
under this Agreement and the other Credit Documents as any other Bank and may
exercise the same as though CLNY were not the Agent or Canadian Imperial were
not the Syndication Agent, as the case may be, and the terms "Bank" and "Banks"
shall include each of CLNY and CIBC Inc. in its individual capacity.

         12.9     Successor Agent. The Agent may, and at the request of the
Required Banks shall, resign as Agent upon 30 days' notice to the Banks. If the
Agent shall resign as Agent under this Agreement and the other Credit Documents,
the Required Banks shall appoint a successor agent for the Banks which successor
agent shall be subject to approval by the Company, which approval will not
unreasonably be withheld or delayed. If no successor Agent is appointed prior to
the effective date of the resignation of the Agent, the Agent shall appoint,
after consulting with the Banks and the Company, a successor agent. Upon the
acceptance of its appointment as successor agent under this Agreement and the
other Credit Documents, such successor agent shall succeed to all the rights,
powers and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties, obligations and liabilities as Agent under the
Credit Documents. After any retiring Agent's resignation as Agent, the
provisions of this Article XII and Sections 13.4 and 13.5 shall continue to
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Agent under this Agreement and the other Credit Documents. Any successor
Agent shall be a bank or financial institution which has an office in the United
States and a combined capital and surplus of at least $250,000,000 and with its
deposits insured by the FDIC.

         12.10    Collateral Matters.

                  (a)      The Agent is authorized on behalf of all the Banks,
without the necessity of any notice to or further consent from the Banks, from
time to time, to take any action with respect to any Collateral or Security
Documents which may be necessary to perfect and maintain perfected the security
interest in and Liens upon the Collateral granted pursuant to the Security
Documents. The Agent is further authorized on behalf of all the Banks, without
the necessity of any notice to or further consent from the Banks, from time to
time, to take any action in exigent circumstances as may be reasonably necessary
to preserve any rights or privileges of the Banks under the Credit Documents or
applicable law.

                  (b)      The Banks irrevocably authorize the Agent, at its
option and in its discretion, to release any Lien granted to or held by the
Agent upon any Collateral (i) upon termination of the Commitments and payment in
full of all Loans and expiration of the Letters of Credit and all other
Obligations payable under this Agreement and under any other Credit Document;
(ii) constituting property sold or to be sold or disposed of as

                                      124
<PAGE>
part of or in connection with any disposition permitted under this Agreement or
the other Credit Documents; (iii) constituting property in which the Company or
any Subsidiary of the Company owned no interest at the time the Lien was granted
or at any time thereafter; (iv) constituting property leased to the Company or
any Subsidiary of the Company under a lease which has expired or been terminated
in a transaction permitted under this Agreement or is about to expire and which
has not been, and is not intended by the Company or such Subsidiary to be,
renewed or extended; (v) consisting of an instrument evidencing Indebtedness or
other debt instrument, if the indebtedness evidenced thereby has been paid in
full; or (vi) if approved, authorized or ratified in writing by the Required
Banks or all the Banks, as the case may be, as provided in Section 13.1(g). Upon
request by the Agent at any time, the Banks will confirm in writing the Agent's
authority to release particular types or items of Collateral pursuant to this
Section 12.10(b).

                                  ARTICLE XIII
                                  MISCELLANEOUS

         13.1     Amendments and Waivers. No amendment or waiver of any
provision of this Agreement or any other Credit Document and no consent with
respect to any departure by any Obligor therefrom shall be effective unless the
same shall be in writing and signed by the Required Banks, and then such waiver
shall be effective only in the specific instance and for the specific purpose
for which given; provided, however, that no such waiver, amendment, or consent
shall, unless in writing and signed by all the Banks, do any of the following:

                  (a)      increase the Total Commitment (except as contemplated
by Section 4.8), or increase the Commitment of any Bank without such Bank's
consent or subject any Bank to any additional obligations without such Bank's
consent;

                  (b)      postpone or delay any date fixed for any payment of
principal, interest, fees or other amounts due under this Agreement or any other
Credit Document;

any Loan, any Letter of Credit Obligation or of any fees or other amounts

                  (d)      change the percentage of the Commitments or of the
aggregate unpaid principal amount of the Loans or Letter of Credit Obligations

this Agreement or any other Credit Document;

                  (e)      release any Guarantor from all or substantially all
of its Obligations under Article XI;

                  (f)      amend this Section 13.1 or Section 5.9; or

                  (g)      release all or substantially all of the Collateral
except as otherwise provided in the Security Documents or except where the
consent of the Required Banks only is specifically provided for;

                                      125

writing and signed by the Agent in addition to the Required Banks, (x) affect
the rights or duties of the Agent under this Agreement or any other Credit
Document, (y) modify any Event of Default, or (z) modify the provisions
governing the calculation of the Net Borrowing Base.

by telex answerback or delivered to the cable company, respectively, or (iv) if
delivered, upon delivery, except that notices pursuant to Article II or X shall
not be effective until received by the Agent. Actual notice shall always be
effective.

         13.3     No Waiver; Cumulative Remedies. No failure to exercise and no
delay in exercising, on the part of any Agent or any Bank, any right, remedy,
power or privilege under this Agreement or any other Credit Document shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, remedy, power or privilege under this Agreement or any other Credit
Document preclude any other or further exercise thereof or the exercise of any
other right, remedy, power or privilege. The rights, remedies, powers and
privileges provided in this Agreement and the other Credit Documents are
cumulative and not exclusive of any rights, remedies, powers and privileges
provided by law.

         13.4     Costs and Expenses. Each Obligor agrees

                  (a)      to pay or reimburse the Agent on demand for all its

preparation, delivery, administration and execution of, and any amendment,
supplement, waiver or modification to, this Agreement, any other Credit Document
and any other documents prepared in connection herewith or therewith, and the
consummation of the transactions

contemplated hereby and thereby, including the reasonable costs and expenses of

with respect thereto;

                  (b)      to pay or reimburse each Bank, the Issuing Bank, the
Agent, Lead Arranger, the Joint Lead Arranger, the Joint Book Runners, and the
Syndication Agent on demand for all reasonable costs and expenses incurred by
them in connection with the enforcement or preservation of any rights (including
in connection with any "workout" or restructuring regarding the Loans or Letters
of Credit) under this Agreement, any other Credit Document, and any such other
documents, including reasonable fees and expenses of counsel (and the reasonable
allocated cost of internal counsel) to each of them; and

                  (c)      to pay or reimburse the Agent on demand for all

(b) above.

         13.5     Indemnity.

                  (a)      EACH OBLIGOR SHALL PAY, INDEMNIFY, AND HOLD EACH
BANK, EACH ISSUING BANK, THE AGENT, THE SYNDICATION AGENT, THE LEAD ARRANGER,
THE JOINT LEAD ARRANGER AND EACH JOINT BOOK RUNNER, AND EACH OF THEIR RESPECTIVE
AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS AND ATTORNEYS-IN-FACT (EACH,

ENVIRONMENTAL CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
JUDGMENTS, SUITS, COSTS, CHARGES, EXPENSES OR DISBURSEMENTS (INCLUDING
REASONABLE FEES AND EXPENSES OF COUNSEL AND THE REASONABLE ALLOCATED COST OF
INTERNAL COUNSEL) OF ANY KIND OR NATURE WHATSOEVER WITH RESPECT TO THE
EXECUTION, DELIVERY, ENFORCEMENT, PERFORMANCE AND ADMINISTRATION OF THIS
AGREEMENT AND ANY OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREIN
AND THEREIN, AND WITH RESPECT TO ANY INVESTIGATION, LITIGATION OR PROCEEDING
RELATED TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT OR THE LOANS OR LETTERS
OF CREDIT OR THE USE OF THE PROCEEDS THEREOF, WHETHER OR NOT ANY INDEMNIFIED
PERSON IS A PARTY THERETO (ALL THE FOREGOING, COLLECTIVELY, THE "INDEMNIFIED
LIABILITIES"), WHETHER OR NOT ANY OF THE FOREGOING SPECIFIED IN THIS SECTION
13.5 ARISES FROM THE SOLE OR CONCURRENT NEGLIGENCE OF ANY INDEMNIFIED PERSON;
PROVIDED, THAT THE OBLIGORS SHALL HAVE NO OBLIGATION UNDER THIS SECTION 13.5 TO
ANY INDEMNIFIED PERSON WITH RESPECT TO INDEMNIFIED LIABILITIES WHICH ARE
DETERMINED IN A FINAL JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE
RESULTED FROM THE GROSS NEGLIGENCE, BAD FAITH OR WILLFUL MISCONDUCT OF SUCH
INDEMNIFIED PERSON. THE AGREEMENTS IN THIS SECTION 13.5 SHALL SURVIVE REPAYMENT
OF ALL OTHER OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT.

                                      127
<PAGE>
                  (b)      No action taken by legal counsel chosen by any
Indemnified Person in defending against any such investigation, litigation or
proceeding or in any requested remedial, removal or response action shall
vitiate or any way impair the Obligors' obligation and duty under this Agreement
to indemnify and hold harmless each Indemnified Person as provided hereunder.

                  (c)      In no event shall any site visit, observation, or
testing by any Indemnified Person be a representation that Hazardous Materials
are or are not present in, on, or under any property or facility owned,
operated, leased or controlled by any of the Obligors or any of their
Subsidiaries or that there has been or shall be compliance with any Legal
Requirement pertaining to Hazardous Materials or any other applicable Legal
Requirement. No Obligor nor any other Person is entitled to rely on any site
visit, observation, or testing by any Indemnified Person. No Indemnified Person
owes any duty of care to protect any Obligor or any other Person against, or to
inform any Obligor or any other Person of, any Hazardous Materials or any other
adverse condition affecting any property or facility owned, operated, leased or
controlled by any Obligor or any Subsidiary of any Obligor. No Indemnified
Person shall be obligated to disclose to any Obligor or any other Person any
report or findings made as a result of, or in connection with, any site visit,
observation, or testing by any Indemnified Person.

         13.6     Successors and Assigns. The provisions of this Agreement and
the other Credit Documents shall be binding upon and inure to the benefit of the
Parties and their respective successors and assigns, except that no Obligor (as
a Borrower or as a Guarantor) may assign or transfer any of its rights or
obligations under this Agreement or any other Credit Document without the prior
written consent of each Bank.

         13.7     Assignments, Participations, Etc.

                  (a)      Any Bank may, with the written consent of the Company
(provided no Default shall have occurred and be continuing), the Agent and each
Issuing Bank, which in each case shall not be unreasonably withheld or delayed,
at any time assign and delegate to one or more Eligible Assignees (each of such
Eligible Assignees, an "Assignee") all or any part of the Loans, the Letter of
Credit Obligations or the Commitments or any other rights or obligations of such
Bank under this Agreement and the other Credit Documents in a minimum amount of
Five Million Dollars ($5,000,000); provided, however, that the Obligors and the
Agent shall be entitled to continue to deal solely and directly with such Bank
in connection with the interests so assigned to an Assignee until (i) written
notice of such assignment, together with payment instructions, addresses and
related information with respect to the Assignee, shall have been given to the
Company and the Agent by such Bank and the Assignee and (ii) such Bank and its
Assignee shall have delivered to the Company and the Agent an Assignment and
Assumption in the form of Exhibit N (an "Assignment and Assumption"), together
with any Note or Notes subject to such assignment; and (iii) a processing fee of
Three Thousand Five Hundred Dollars ($3,500) shall have been paid to the Agent
by the Assignee.

                                      128
<PAGE>
                  (b)      From and after the date that the Agent notifies the
assignor Bank that it has received the Assignment and Assumption, (i) the
Assignee thereunder shall be a party to this Agreement and, to the extent that
rights and obligations under this Agreement and the other Credit Documents have
been assigned to it pursuant to such Assignment and Assumption, shall have the
rights and obligations of a Bank under the Credit Documents, and (ii) the
assignor Bank shall, to the extent that rights and obligations under this
Agreement and the other Credit Documents have been assigned by it pursuant to
such Assignment and Assumption, relinquish its rights and be released from its
obligations under the Credit Documents.

                  (c)      Immediately upon each Assignee's making its payment
under the Assignment and Assumption, this Agreement shall be deemed to be
amended to the extent, but only to the extent, necessary to reflect the addition
of the Assignee and the resulting adjustment of the Commitments arising
therefrom. The Commitments allocated to each Assignee shall reduce such
Commitments of the assigning Bank pro tanto.

                  (d)      Any Bank may, with the written consent of the
Company, which shall not be unreasonably withheld or delayed, at any time sell
to one or more banks or other entities (a "Participant") participating interests
in any Loans, any Letter of Credit Obligations, the Commitments of that Bank or
any other interest of that Bank under this Agreement and the other Credit
Documents; provided, however, that (i) the Bank's obligations under this
Agreement and the other Credit Documents shall remain unchanged, (ii) the Bank
shall remain solely responsible for the performance of such obligations, (iii)
the Obligors and the Agent shall continue to deal solely and directly with the
Bank in connection with the Bank's rights and obligations under this Agreement
and the other Credit Documents, and (iv) no Bank shall transfer or grant any
participating interest under which the Participant shall have rights to approve
any amendment to, or any consent or waiver with respect to this Agreement or any
other Credit Document except to the extent such amendment, consent or waiver
would require unanimous consent as described in the first proviso to Section
13.1. In the case of any such participation, the Participant shall not have any
rights under this Agreement or any of the other Credit Documents, and all
amounts payable by any Obligor under the Credit Documents shall be determined as
if such Bank had not sold such participation, except that each Obligor agrees
that if amounts outstanding under this Agreement or any other Credit Document
are due and unpaid, or shall have been declared or shall have become due and
payable upon the occurrence of an Event of Default, each Participant shall have
the right of set-off in respect of its participating interest in amounts owing
under this Agreement and the other Credit Documents to the same extent as if the
amount of its participating interest were owing directly to it as a Bank under
this Agreement and the other Credit Documents.

                  (e)      Notwithstanding any other provision set forth in this
Agreement, any Bank may at any time create a security interest in all or any
portion of its rights under this Agreement (including the Loans owing to it and
any Note payable to it) in favor of any Federal Reserve Bank in accordance with
Regulation A of the Federal Reserve Board of the United States or any other
applicable law or regulation.

         13.8     Confidentiality. The Agent and each Bank agree:

                  (a)      to use the same level of precaution as is used to
protect their own valuable confidential information to keep any information
delivered or made available to it by any Obligor or by the Agent on behalf of
any Obligor (including any information obtained pursuant to Section 8.1)
(collectively, the "Information") confidential from anyone other than Persons
entitled or permitted to receive the same pursuant to this Section 13.8;

                  (b)      not to use the Information other than for the
purposes of evaluating, structuring, negotiating, documenting, syndicating,
participating, administering, performing and enforcing the Credit Documents and
Obligations of the Obligors and conducting due diligence activities with respect
to the Obligors and their Subsidiaries;

                  (c)      to inform their respective directors, officers,
employees, agents, auditors, legal counsel, internal analysts, compliance
personnel and other representatives (collectively, the "representatives") of the
confidential nature of the Information and to be responsible for any violation
of this Section 13.8 by any of their respective representatives;

                  (d)      not to engage in any securities transactions relating
to the Company's securities in violation of the restrictions imposed on it by
applicable federal securities laws, or to assist others in doing so
(understanding that trading in the Company's securities while in possession of
the Information could under certain circumstances constitute such a violation);
and

                  (e)      in the event it is requested or required in a legal
or administrative proceeding by subpoena, civil investigative demand,
interrogatories, requests for information or other similar process to disclose
any of the Information, to (unless prohibited from doing so) provide the Company
with prompt notice of such request(s) so that the Company may seek an
appropriate protective order and/or waive compliance with this Section 13.8;

provided, however, that nothing in this Section 13.8 shall prevent the Agent,
any Bank, any representative of the Agent or any Bank or any Transferee (as
defined below) from disclosing the Information (i) to any other Bank, (ii)
pursuant to subpoena or upon the order of any Governmental Authority or as
required by any applicable Legal Requirement, (iii) upon the request or demand
of any regulatory agency or authority having jurisdiction over the Agent or such
Bank, (iv) which is or becomes generally available to the public, other than as
a result of a violation of this Section 13.8 by the Agent, any Bank or any
representative of the Agent or any Bank, (v) to the extent reasonably required
in connection with any litigation to which the Agent, any Bank, or their
respective Affiliates or representatives may be a party, (vi) to the extent
reasonably required in connection with the exercise of any remedy hereunder or
under any other Credit Document, at law or in equity, or (vii) to the Agent's or
such Bank's representatives.

                                      130
<PAGE>
The Company and each other Obligor, for themselves and their Subsidiaries,
irrevocably authorize the Agent, each Bank, and their respective representatives
to disclose to any Participant or Assignee (each, a "Transferee"), to any such
Transferee's representatives, to any prospective Transferee and to the
representatives of any prospective Transferee such financial and other
information concerning the Company and its Subsidiaries which has been or may at
any time be delivered to the Agent or any Bank or any such representative
pursuant to this Agreement or any other Credit Document or which has been or may
at any time be delivered to the Agent or any Bank or any such representative by
the Company or any of its Subsidiaries or any representative of the Company or
any of its Subsidiaries; provided that such Transferee agrees to keep such
information confidential to the same extent required of the Banks under this
Agreement and the other Credit Documents.

The Company shall be entitled to equitable relief by way of injunction if the
Agent, any Bank or any representative of the Agent or any Bank breached or
threatens to breach any of the provisions of this Section 13.8.

         13.9     Set-off. In addition to any rights and remedies of the Banks
provided by law, upon the occurrence and during the continuation of any Event of
Default each Bank is hereby authorized at any time and from time to time,
without prior notice to any Obligor, any such notice being expressly WAIVED by
each Obligor to the fullest extent permitted by applicable law, to set-off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other indebtedness at any time owing by such Bank to
or for the credit or the account of the Obligors or any of them against any and
all Obligations of the Obligors or any of them now or hereafter existing under
this Agreement or any other Credit Document and any Loan held by such Bank,
including Obligations of the Obligors as Guarantors under Article XI,
irrespective of whether the Agent or such Bank shall have made demand under this
Agreement or any other Credit Document and although such Obligations may be
contingent or unmatured. Each Bank agrees promptly to notify the Company and the
Agent after any such set-off and application made by the Bank; provided,
however, that the failure to give such notice shall not affect the validity of
such set-off and application. The rights of each Bank under this Section 13.9
are in addition to the other rights and remedies (including other rights of
set-off) which such Bank may have.

         13.10    Limitation of Interest. The Obligors and the Banks intend to
strictly comply with all applicable laws, including applicable usury laws.
Accordingly, the provisions of this Section 13.10 shall govern and control over
every other provision of this Agreement or any other Credit Document which
conflicts or is inconsistent with this Section 13.10, even if such provision
declares that it controls. As used in this Section 13.10, the term "interest"
includes the aggregate of all charges, fees, benefits or other compensation
which constitute interest under applicable law; provided, that, to the maximum
extent permitted by applicable law, (a) any non-principal payment shall be
characterized as an expense and not as interest, and (b) all interest at any
time contracted for, reserved, charged or received shall be amortized, prorated,
allocated and spread, in equal parts during the full term of the Obligations. In
no event shall any Obligor or any other Person be obligated to pay, or the Agent
or any Bank have any right or privilege to

                                      131
<PAGE>
reserve, receive or retain, any interest in excess of the maximum amount of
nonusurious interest permitted under applicable law. None of the terms and
provisions contained in this Agreement or in any other Credit Document which
directly or indirectly relate to interest shall ever be construed without
reference to this Section 13.10, or be construed to create a contract to pay
interest at a rate in excess of the maximum nonusurious rate permitted by
applicable law. If for any reason any Bank at any time, including the stated
maturity, is owed or receives (and/or has received) interest in excess of
interest calculated at the maximum nonusurious rate permitted by applicable law,
then and in any such event all of any such excess interest shall be cancelled
automatically as of the date of such acceleration, prepayment or other event
which produces the excess, and, if such excess interest has been paid to such
Bank, it shall be credited pro tanto against the then-outstanding principal
balance of the Obligations to such Bank, effective as of the date or dates when
the event occurs which causes it to be excess interest, until such excess is
exhausted or all of such principal has been fully paid and satisfied, whichever
occurs first, and any remaining balance of such excess shall be promptly
refunded to its payor.

         13.11    Notification of Addresses, Lending Offices, Etc. Each Bank
shall notify the Agent in writing of any changes in the address to which notices
to the Bank should be directed, of addresses of its Eurodollar Lending Office
and its Domestic Lending Office, of payment instructions in respect of all
payments to be made to it under this Agreement or the other Credit Documents and
of such other administrative information as the Agent shall reasonably request.

         13.12    Counterparts. This Agreement and the other Credit Documents
may be executed by one or more of the parties to them in any number of separate
counterparts, each of which, when so executed, shall be deemed an original, and
all of said counterparts taken together shall be deemed to constitute but one
and the same agreement. Copies of this Agreement and each other Credit Document
signed by all Parties shall be lodged with the Company and the Agent.

         13.13    Severability. The illegality or unenforceability of any
provision of this Agreement or any other Credit Document or any instrument or
agreement required by this Agreement or any other Credit Document shall not in
any way affect or impair the legality or enforceability of the remaining
provisions of this Agreement or any other Credit Document or any instrument or
agreement required by this Agreement or any other Credit Document.

         13.14    Governing Law and Jurisdiction; Waivers and Releases.

                  (a)      THIS AGREEMENT AND EACH OTHER CREDIT DOCUMENT AND

LEAD ARRANGER, THE JOINT LEAD ARRANGER, EITHER JOINT BOOKRUNNER, OR ANY OF THE
BANKS MAY HAVE UNDER THE NATIONAL BANK ACT OR OTHER APPLICABLE FEDERAL LAW.

                  (c)      ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS
AGREEMENT OR ANY OTHER CREDIT DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE
OF NEW YORK LOCATED IN THE BOROUGH OF MANHATTAN OR OF THE UNITED STATES OF
AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND BY EXECUTION AND DELIVERY OF

PARTY TO THIS AGREEMENT WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR
OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY NEW YORK LAW.

                  (d)      EACH OF THE PARTIES TO THIS AGREEMENT HEREBY
IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER CREDIT
DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED BY ANY CREDIT DOCUMENT.

                  (e)      EACH OBLIGOR HAS IRREVOCABLY APPOINTED CT CORPORATION
SYSTEM (THE "PROCESS AGENT"), WITH AN OFFICE ON THE DATE HEREOF AT 111 EIGHTH
AVE., NEW YORK, NEW YORK, 10011, AS ITS AGENT TO RECEIVE ON ITS BEHALF AND ON

PROCESS AGENT AT THE PROCESS AGENT'S ABOVE ADDRESS, AND EACH OBLIGOR HEREBY
IRREVOCABLY AUTHORIZES AND DIRECTS THE PROCESS AGENT TO ACCEPT SUCH SERVICE ON
ITS BEHALF. AS AN ALTERNATIVE METHOD OF SERVICE, EACH OBLIGOR ALSO IRREVOCABLY
CONSENTS TO THE SERVICE OF ANY AND ALL PROCESS IN ANY SUCH ACTION OR PROCEEDING
BY THE MAILING OF COPIES OF SUCH PROCESS TO IT AT THE ADDRESS SPECIFIED FOR IT
ON THE SIGNATURE PAGES OF THIS AGREEMENT OR IN ITS ELECTION TO PARTICIPATE.

                  (f)      NOTHING IN THIS SECTION 13.14 SHALL AFFECT THE RIGHT
OF THE AGENT OR ANY OTHER BANK TO SERVE LEGAL PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW OR AFFECT THE RIGHT OF THE AGENT OR ANY OTHER BANK TO BRING ANY
ACTION OR PROCEEDING AGAINST ANY OBLIGOR (AS A BORROWER OR AS A GUARANTOR) IN
THE COURTS OF ANY OTHER JURISDICTION.

                  (g)      TO THE EXTENT ANY OBLIGOR HAS OR HEREAFTER MAY
ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS
(WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN
AID OF EXECUTION, EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS
PROPERTY, SUCH OBLIGOR HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS
OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS.

                  (h)      AS REGARDS THE SERVICE OF PROCESS, THE DISCOVERY
PROCESS, AND ANY JUDICIAL, QUASI-JUDICIAL, OR SIMILAR PROCEEDING, EACH OF THE
PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT
PERMITTED BY LAW, ALL PRIVILEGES, RIGHTS, AND LEGAL RESTRICTIONS BENEFITTING IT
THAT DO NOT ACCRUE TO SUCH PARTY (AND THAT WOULD NOT ACCRUE TO SUCH PARTY WERE
ALL RELEVANT CIRCUMSTANCES TO HAVE OCCURRED IN NEW YORK AMONG NEW YORK
RESIDENTS) UNDER THE LAWS OF NEW YORK (EXCLUDING ITS CONFLICTS OF LAWS RULES).
WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, THE PARTIES AGREE THAT, TO THE
EXTENT APPLICABLE LAW PERMITS WAIVER, ANY REQUIREMENTS OR LIMITATIONS IMPOSED
UNDER ANY OF THE HAGUE CONVENTION ON THE SERVICE ABROAD OF JUDICIAL AND
EXTRAJUDICIAL DOCUMENTS, THE HAGUE CONVENTION ON THE TAKING OF EVIDENCE ABROAD

BORROWER AND AS A GUARANTOR) HEREBY RELEASES, DISCHARGES AND ACQUITS FOREVER THE
AGENT, THE BANKS AND THEIR RESPECTIVE OFFICERS, DIRECTORS, TRUSTEES, AGENTS,
EMPLOYEES AND COUNSEL (IN EACH CASE, PAST, PRESENT OR FUTURE) FROM ANY AND ALL
CLAIMS EXISTING AS OF THE DATE HEREOF (OR THE DATE OF ACTUAL EXECUTION HEREOF BY

<PAGE>
CONTINGENT, AND WHETHER ARISING OUT OF WRITTEN DOCUMENTS, UNWRITTEN
UNDERTAKINGS, COURSE OF CONDUCT, TORT, VIOLATIONS OF LAWS OR REGULATIONS OR
OTHERWISE.

         13.15    Construction. The Parties agree that this Agreement and the
other Credit Documents were negotiated agreements and accordingly no presumption
shall attach based on the identity of the drafting party.

         13.16    ENTIRE AGREEMENT. THIS AGREEMENT TOGETHER WITH THE OTHER
CREDIT DOCUMENTS EMBODIES THE ENTIRE AGREEMENT AND UNDERSTANDING AMONG THE
PARTIES TO IT AND SUPERSEDES ALL PRIOR OR CONTEMPORANEOUS AGREEMENTS AND
UNDERSTANDINGS OF SUCH PERSONS, VERBAL OR WRITTEN, RELATING TO THE SUBJECT
MATTER HEREOF EXCEPT FOR THE FEE LETTER AND ANY PRIOR ARRANGEMENTS MADE WITH
RESPECT TO THE PAYMENT BY ANY OBLIGOR OF (OR ANY INDEMNIFICATION FOR) ANY FEES,
COSTS OR EXPENSES PAYABLE TO OR INCURRED (OR TO BE INCURRED) BY OR ON BEHALF OF
THE AGENT, THE ISSUING BANK, THE BANKS, THE LEAD ARRANGER, THE JOINT LEAD
ARRANGER, THE JOINT BOOK RUNNERS, OR THE SYNDICATION AGENT.

         13.17    Conflict with Security Documents. The benefits, rights and
remedies of the Banks and Agent and the security contained in or provided for in
the Credit Documents are cumulative; provided, however, that if the provisions
of the other Credit Documents conflict with any provision of this Agreement,
this Agreement shall control to the extent of such conflict, unless the
applicable provisions of the other Credit Documents increase the rights of the
Banks and Agent, in which event the terms of the other Credit Documents shall
control.

         13.18    Termination. In the event that the Commitments have been
reduced to zero, no Letters of Credit are outstanding and all Loans and other
Obligations have been fully and finally paid, this Agreement shall terminate
(except for provisions expressly stated to survive any such termination), and
the Agent and the Banks shall, upon the request and at the cost and expense of
the Company, cause to be executed and delivered such releases of Collateral,
assignments or other documents or instruments to evidence such termination as
the Company shall reasonably request. For the purposes of this Section 13.18,
there shall be deemed to be no Letters of Credit outstanding if the Company
shall have taken the actions required by Section 10.3 (other than in connection
with a Default or Event of Default). Each Obligor agrees that if at any time all
or any part of any payment previously applied by any Bank to any Loan or other
Obligation is or must be returned by or recovered from such Bank for any legally
binding reason (including the order of any bankruptcy court), to the fullest
extent not prohibited by applicable law, the Credit Documents shall
automatically be reinstated to the same effect as if the prior application had
not been made, and, to the fullest extent not prohibited by applicable law, each
Obligor hereby agrees to indemnify each such payee against, and to save and hold
each such payee harmless from, any required return by or recovery from such

         13.19    Currency Conversion. If any sum due from any Obligor under
this Agreement or any other Credit Document or in connection herewith or any
order or judgment given or made in relation to this Agreement or any other
Credit Document has to be converted from the currency (the "first currency") in
which the same is payable hereunder or under such order or judgment into another
currency (the "second currency") for the purpose of (a) making or filing a claim
of proof against any Obligor with any Governmental Authority or in any court or
tribunal; (b) obtaining an order or judgment in any court or other tribunal; or
(c) enforcing any order or judgment given or made in relation to this Agreement
or any other Credit Document, the equivalent of such first currency amount in
any second currency shall be calculated based on the spot rate for the purchase
of the first currency with the second currency quoted by CLNY in New York, New
York at approximately 10:00 a.m. on the date for such determination. The
Obligors shall jointly and severally indemnify and hold harmless each of the
Persons to whom such sum is due from and against any loss suffered as a result
of any discrepancy between (i) the rate of exchange used for such purpose to
convert the sum in question from the first currency into the second currency and
(ii) the rate or rates of exchange at which such Person may in the ordinary
course of business purchase the first currency with the second currency upon
receipt of a sum paid to it in satisfaction, in whole or in part, of any such
order, judgment, claim or proof. The foregoing indemnity shall constitute a
separate joint and several obligation of the Obligors distinct from the
Obligations and shall survive the giving or making of any judgment or order in
relation to all or any of the Obligations.

         13.20    No Obligations. Notwithstanding anything herein or in any
other Credit Document to the contrary, none of CLNY, CIBC World Markets Corp. or
Canadian Imperial shall have any duties, responsibilities, liabilities or
obligations under this Agreement in their respective capacities as Lead
Arranger, Joint Book Runner, Joint Lead Arranger or Syndication Agent, or any
fiduciary or trustee relationship with any Bank, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Credit Document or otherwise exist against the
Lead Arrangers, Joint Book Runners, Joint Lead Arranger or Syndication Agent.

                        FORM OF ACCOUNT CONTROL AGREEMENT

                            ACCOUNT CONTROL AGREEMENT

         This Account Control Agreement (this "Control Agreement") dated as of
June 14, 2002, among [GRANTOR] (the "Grantor"), Credit Lyonnais New York Branch,
as Agent under the Credit Agreement described herein (acting in such capacity
hereunder, the "Agent"), and [ACCOUNT BANK], as the financial institution
maintaining the Account described herein (the "Account Bank"). Terms used herein
which are defined in the Uniform Commercial Code in effect in the State of New
York ("New York UCC") shall have the meaning set forth in the New York UCC.

                             PRELIMINARY STATEMENTS:

         (1) The Grantor and certain of its affiliates (the "Obligors") have
entered into a Credit Agreement dated as of June 14, 2002, among [Grantor]
[Willbros Group, Inc.] and the other Obligors from time to time; the several
financial institutions from time to time parties thereto (the "Banks"); Credit
Lyonnais New York Branch, as a Bank, as Issuing Bank, as administrative agent
for the Banks (in such capacity the "Agent"), and as Lead Arranger and Joint
Book Runner; CIBC World Markets Corp., as Joint Lead Arranger and Joint Book
Runner; and Canadian Imperial Bank of Commerce, as Syndication Agent (as
amended, supplemented or modified from time to time in accordance with its
terms, the "Credit Agreement").

         (2) Pursuant to the Security Agreement dated as of June 14, 2002, among
the Obligors and the Agent, for the benefit of the Secured Parties described
therein (the "Security Agreement"), and as a condition to the credit provided
under the Credit Agreement, the Grantor has granted to the Agent for the benefit
of the Secured Parties (as defined in the Credit Agreement) to secure the
Secured Obligations (as defined in the Security Agreement) a first priority
security interest (the "Agent's Security Interest") in certain assets of the
Grantor, including without limitation all of Grantor's right, title and interest
in and to the following assets (collectively herein called the "Account
Collateral"): (i) the [TYPE OF ACCOUNT -- DEPOSIT, LOCK-BOX OR OTHER DESCRIPTION
OF RELEVANT ACCOUNT] account identified as Account No. _______________
maintained by the Account Bank in the name of the Grantor at the office of the
Account Bank in [LOCATION OF ACCOUNT BANK] (the "Account"), (ii) all interest
and other earnings in respect of the Account, (iii) all checks, drafts, wire
transfers, receipts, and financial assets credited to the Account from time to
time, and (iv) all contract rights and privileges in respect of the Account.

         (3) In order to perfect the Agent's Security Interest in the Account
Collateral, the parties are entering into this Control Agreement.

         NOW, THEREFORE, in consideration of the premises and of the mutual
agreements contained herein, the parties hereto hereby agree as follows:
<PAGE>
         SECTION 1. The Account. The Account Bank represents and warrants to,
and agrees with, the Agent that:

         (a) The Account Bank maintains the Account Collateral for the Grantor
subject to the Agent's Security Interest, and all property (including, without
limitation, all funds and financial assets) held by the Account Bank for the
account of the Grantor are, and will continue to be, credited to the Account in
accordance with instructions given by the Grantor (unless otherwise provided
herein).

         (b) The Account is a [TYPE OF ACCOUNT] account, the Account Bank is the
bank with which the Account is maintained, and the Grantor is the Account Bank's
customer with respect to the Account.

         (c) Notwithstanding any other agreement to the contrary, the Account
Bank's jurisdiction with respect to the Account Collateral for purposes of the
New York UCC is, and will continue to be for so long as the Agent's Security
Interest of the Agent shall be in effect, the State of New York.

         (d) The Account Bank does not know of any claim to or interest in the
Account Collateral, except for claims and interests of the Agent pursuant to the
Security Agreement and this Control Agreement.

         SECTION 2. Control by Secured Party. Notwithstanding anything to the
contrary in any other agreement between the Grantor and the Account Bank, the
Account Bank agrees that, upon receipt of the Notice of Exclusive Control (as
defined below), it will comply with (i) all instructions of the Agent directing
disposition of the Account Collateral, including, without limitation, the funds
in the Account, and (ii) all other directions of the Agent concerning the
Account Collateral, including, without limitation, directions to distribute to
the Agent proceeds of any interest or other earnings or financial assets
credited to the Account (any such instruction, notification or direction
referred to in clause (i) or (ii) above being an "Account Direction"), in each
case of clauses (i) or (ii) above, without further consent or direction by the
Grantor or any other person or entity.

         SECTION 3. Grantor's Rights in the Account.

         (a) The Agent hereby agrees with the Account Bank that, at any time
prior to the Effective Time (as defined below), the Account Bank shall comply
with Account Directions and other directions concerning the Account Collateral
originated by the Grantor without any further consent by the Agent, and the
Account Bank may distribute to the Grantor all funds in the Account, and all
interest, earnings or financial assets credited to the Account.

         (b) For the purposes hereof, the "Effective Time" shall be the opening
of business on the second business day next succeeding the business day on which
a notice purporting to be signed by the Agent in substantially the same form as
Annex A attached hereto, with a copy of this Control Agreement attached thereto
(a "Notice of Exclusive Control"), is actually received by one of the individual
employees of the Account Bank to whom the notice is required hereunder to be
addressed; provided, however, that if any such notice is so received after 12:00
noon, New York City time, on any business day, the "Effective Time" shall be the
opening of

                                       2
<PAGE>
business on the third business day next succeeding the business day on which
such receipt occurs; and, provided further, that a "business day" is any day
other than a Saturday, Sunday or other day on which the Account Bank is
authorized or required by law to be closed.

         (c) From and after receipt by the Account Bank of a Notice of Exclusive
Control from the Agent with respect to the Account, the Account Bank will
thereafter at all times comply only with Account Directions originated by the
Agent in respect of the Account Collateral, and will cease: (i) complying with
Account Directions or other directions concerning the Account originated by the
Grantor, and (ii) distributing to the Grantor interest, earnings or financial
assets credited to the Account, or funds in the Account.

         (d) Notwithstanding the foregoing: (i) all transactions involving or
resulting in a transaction involving the Account Collateral duly commenced by
the Account Bank or any of its affiliates prior to the Effective Time and so
consummated or processed thereafter shall be deemed not to constitute a
violation of the Control Agreement; and (ii) the Account Bank and/or any of its
affiliates may (at its discretion and without any obligation to do so) commence
honoring solely Agent's instructions concerning the Account Collateral at any
time or from time to time after it becomes aware that the Agent has sent to it a
Notice of Exclusive Control but prior to the Effective Time therefor (including
without limitation halting, reversing or redirecting any transaction referred to
in clause (i) above) with no liability whatsoever to the Grantor or any other
party for doing so.

         This Control Agreement supplements, rather then replaces, the Account
Bank's [TYPE OF ACCOUNT] account agreement, terms and conditions and other
standard documentation in effect from time to time with respect to the Account
Collateral or services provided in connection with the Account Collateral (the
"Account Documentation"), which Account Documentation will continue to apply to
the Account Collateral and such services, and the respective rights, powers,
duties, obligations, liabilities and responsibilities of the parties thereto and
hereto, to the extent not expressly conflicting with the provisions of this
Control Agreement (however, in the event of any such conflict, the provision of
this Control Agreement shall control). Prior to issuing any instructions on or
after the Effective Time, the Agent shall provide the Account Bank with such
Account Documentation as the Account Bank may reasonably request to establish
the identity and authority of the individuals issuing instructions on behalf of
the Agent.

         SECTION 4. Priority of Agent's Security Interest.

         (a) The Account Bank hereby (i) subordinates to the Agent's Security
Interest and in favor of the Agent any security interest, lien, or right of
recoupment or setoff that the Account Bank may have, as long as this Control
Agreement is in effect, against the Account Collateral, and (ii) agrees that it
will not exercise any right in respect of any such security interest or lien or
any such right of recoupment or setoff until the Agent's Security Interest is
terminated, except that the Account Bank (A) will retain a prior security
interest and lien on property credited to the Account, (B) may exercise any
right in respect of such security interest or lien, and (C) may exercise any
right of recoupment or setoff against the Account, in the case of clauses (A),
(B) and (C) above, to secure or to satisfy, and only to secure or to satisfy,
(i) payment of its customary fees and expenses for the routine maintenance and
operation of the Account Collateral

                                       3
<PAGE>
and (ii) payment of the face amount of any items that have been credited to such
Account but are subsequently returned unpaid because of uncollected or
insufficient funds or for any electronic or wire transfers credited to the
Account but returned for any reason.

         (b) The Account Bank will not enter into any other agreement with any
Person relating to Account Directions or other directions with respect to the
Account Collateral.

         SECTION 5. Statements, Confirmations and Notices.

         (a) The Account Bank will send copies of all statements and
confirmations for the Account simultaneously to the Agent and the Grantor.

         (b) When any party hereto knows of any claim or interest in the Account
Collateral other than the claims and interests of the Agent and the Grantor,
such party will promptly notify the other parties of such claim or interest.

         SECTION 6. The Account Bank's Responsibility.

         (a) Except for permitting a withdrawal, delivery or payment in
violation of Section 3 of this Control Agreement, the Account Bank will not be
liable to the Agent for complying with Account Directions or other directions
concerning the Account from the Grantor that are received by the Account Bank
before the Account Bank receives a Notice of Exclusive Control from the Agent
under Section 3 hereof.

         (b) The Account Bank will not be liable to the Grantor or the Agent for
complying with a Notice of Exclusive Control or with an Account Direction or
other direction concerning the Account Collateral originated by the Agent, even
if the Grantor notifies the Account Bank that the Agent is not legally entitled
to issue the Notice of Exclusive Control or Account Direction or such other
direction unless the Account Bank takes the action after it is served with an
injunction, restraining order, or other legal process enjoining it from doing
so, issued by a court of competent jurisdiction, and had a reasonable
opportunity to act on the injunction, restraining order or other legal process.

         (c) This Control Agreement does not create any obligation of the
Account Bank except for those expressly set forth in this Control Agreement and
in Article 4 of the New York UCC, and the Account Bank shall not be deemed to be
an agent, bailee or fiduciary for any party hereto. In particular, the Account
Bank need not investigate whether the Agent is entitled under the Agent's
agreements with the Grantor to give an Account Direction or other direction
concerning the Account or a Notice of Exclusive Control. The Account Bank may
rely on notices and communications it believes given by the appropriate party.

         (d) It is hereby acknowledged and agreed that the Account Bank has no
knowledge of (and is not required to know) the terms and provisions of the
separate agreements referred to in paragraphs (1) and (2) above or any other
related documentation or whether any actions by the Agent (including, without
limitation, the sending of a Notice of Exclusive Control), Grantor or any other
person or entity are permitted or a breach thereunder or consistent or
inconsistent therewith. The Account Bank shall not be liable to any party hereto
or any other person for any action or failure to act under or in connection with
this Control Agreement except to the extent

                                       4
<PAGE>
such conduct constitutes its own willful misconduct or gross negligence (and to
the maximum extent permitted by law, shall under no circumstances be liable for
any incidental, indirect, special, consequential or punitive damages); and the
Account Bank shall not be liable for losses or delays caused by force majeure,
interruption or malfunction of computer, transmission or communications
facilities, labor difficulties, court order or decree, the commencement of
bankruptcy or other similar proceedings or other matters beyond the Account
Bank's reasonable control.

         SECTION 7. Indemnity. The Grantor will indemnify, defend, and save
harmless the Account Bank, its officers, directors, employees and agents against
claims, liabilities and expenses (collectively "Covered Items") arising out of
this Control Agreement (including, without limitation, reasonable attorney's
fees and disbursements) or the Account, except to the extent the claims,
liabilities or expenses are caused by the Account Bank's gross negligence or
willful misconduct as found by a court of competent jurisdiction in a final,
non-appealable judgment. The Agent hereby agrees to indemnify and save harmless
the Account Bank against any Covered Items incurred (i) on or after the
Effective Time in connection with this Control Agreement or the Account (except
to the extent due to the Account Bank's willful misconduct or gross negligence),
(ii) at the Agent's direction or instruction (including without limitation the
Account Bank's honoring of a Notice of Exclusive Control), or (iii) due to any
claim by the Agent of an interest in the Account or the funds on deposit
therein.

         SECTION 8. Termination; Survival.

         (a) The Agent may terminate this Control Agreement by notice to the
Account Bank and the Grantor. If the Agent notifies the Account Bank that the
Agent's Security Interest has terminated, this Control Agreement will
immediately terminate.

         (b) The Account Bank may terminate this Control Agreement on 60 days'
prior written notice to the Agent and the Grantor. The Account Bank and the
Grantor will cooperate to make arrangements to transfer all property (including,
without limitation, all funds and financial assets) credited to the Account and
not subject to the Account Bank's control under Section 4 of this Control
Agreement, to another account bank that shall have executed, together with the
Grantor, a control agreement in favor of the Agent in respect of such property
in substantially the form of this Control Agreement or otherwise in form and
substance satisfactory to the Agent. In addition, in the event of a material
breach by the Grantor or the Agent of any of the terms of this Control Agreement
or the Account Documentation, the Account Bank may terminate this Control
Agreement upon sending of at least ten (10) business days' advance written
notice to the other parties hereto. Any other termination or any amendment or
waiver of this Control Agreement shall be effected solely by an instrument in
writing executed by all the parties hereto.

         (c) Sections 6 and 7 will survive termination of this Control
Agreement.

         SECTION 9. Governing Law. This Control Agreement and the Account will
be governed by the law of the State of New York. The Account Bank and the
Grantor may not change the law governing the Account or the law of the Account
Bank's jurisdiction for purposes of the New York UCC without the Agent's express
prior written agreement.

                                       5

         SECTION 10. Captions. The captions and section headings appearing in
this Control Agreement are included solely for convenience of reference and are
not intended to affect the interpretation of any provision of this Control
Agreement.

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

         SECTION 12. Entire Agreement. This Control Agreement is the entire
agreement, and supersedes any prior agreements, and contemporaneous oral
agreements, of the parties concerning its subject matter.

         SECTION 13. Amendments. No amendment of, or waiver of a right under,

                                    EXHIBIT I

                         FORM OF MASTER PLEDGE AGREEMENT

         This MASTER PLEDGE AGREEMENT (this "Agreement"), dated as of June 14,
2002, is made and entered into by WILLBROS GROUP, INC., a Republic of Panama
corporation (the "Company"), and each of the Subsidiaries which is a signatory
hereto or which subsequently becomes a party hereto in accordance with the terms
hereof (together, with the Company, the "Pledgors"), in favor of CREDIT LYONNAIS
NEW YORK BRANCH, acting hereinunder in its capacity as agent (in such capacity,
the "Agent") under the Credit Agreement (defined below).

                             PRELIMINARY STATEMENTS

         1. The Company and certain Designated Subsidiaries from time to time
(the Company and such Designated Subsidiaries collectively, the "Obligors"); the
financial institutions from time to time (the "Banks"); Credit Lyonnais New York
Branch, as a Bank, as Issuing Bank, as administrative agent for the Banks (in
such capacity the "Agent"), and as Lead Arranger and Joint Book Runner; CIBC
World Markets Corp., as Joint Lead Arranger and Joint Book Runner; and Canadian
Imperial Bank of Commerce, as Syndication Agent, are parties to the Credit
Agreement dated as of June 14, 2002 (such Credit Agreement, as amended,
restated, supplemented or otherwise modified from time to time, being
hereinafter referred to as the "Credit Agreement"). Unless otherwise defined
herein, terms defined in the Credit Agreement are used herein as therein
defined. "New York UCC" means, at any time, the Uniform Commercial Code in
effect in the State of New York at that time.

         2. Pursuant to the Credit Agreement, the Banks have agreed to make
available to each Obligor, as a Borrower, a revolving credit facility for loans
and letters of credit, and each Obligor has guaranteed the obligations of each
Borrower pursuant to Section XI of the Credit Agreement.

         3. Each Pledgor is either an Obligor or the direct or indirect parent
of an Obligor, and will derive substantial benefit from each extension of credit
by the Banks under the Credit Agreement.

                                   AGREEMENTS

         In consideration of the premises and in order to induce the Banks to
enter into the Credit Agreement and make the Loans and issue or participate in
the Letters of Credit, and for other good and valuable consideration, the
receipt and sufficiency of which are acknowledged and confessed by the parties,
each Pledgor agrees with the Agent, for the benefit of the Secured Parties as
follows:

         1. Pledge. To secure the Secured Obligations (as defined in Section 2
below), each Pledgor hereby TRANSFERS, GRANTS, BARGAINS, SELLS, CONVEYS,
HYPOTHECATES, SETS OVER, DELIVERS AND PLEDGES to the Agent for the benefit of
<PAGE>
the Secured Parties, and GRANTS to the Agent, for the benefit of the Secured
Parties, a security interest in all of such Pledgor's right, title and interest
of every kind and character now owned or hereafter acquired, created or arising
in and to the following (the "Pledged Collateral"):

                  (a) the Pledged Shares (as defined below);

                  (b) all shares of capital stock, general and limited
partnership interests, limited liability company interests, trust interests,
joint venture interests, ownership rights arising under the law of any
jurisdiction, and any evidence of the foregoing, together with any property and
rights derivative thereof, acquired, received or owned by any Pledgor, which, on
or after the date of this Agreement, is or becomes, as a result of any
occurrence, a Material Subsidiary of the Company;

                  (c) all certificates and similar evidence of ownership
representing the Pledged Shares;

                  (d) all cash dividends, stock dividends, cash, instruments and
other property or proceeds from time to time received, receivable or otherwise
distributed in respect of or in exchange for any or all of the Pledged Shares or
the shares or interests acquired, received or owned under Section 1(b) hereof;
and

                  (e) all additions to and substitutions for any of the
foregoing and all products and proceeds of any of the Pledged Collateral,
together with all renewals and replacements of any of the Pledged Collateral,
all accounts, accounts receivable, instruments, notes, chattel paper, documents
(including all documents of title), books, records, contract rights and general
intangibles arising in connection with any of the Pledged Collateral.

         "Pledged Shares" means, with respect to each Pledgor, all shares
described in Schedule I held by such Pledgor, as amended from time to time,
together with all rights, contingent or otherwise, of such Pledgor to acquire
shares in the entities or organizations represented by the shares described in
Schedule I, as amended from time to time, and all rights to receive cash
dividends, stock dividends, distributions upon redemption or liquidation,
distributions as a result of split-ups, recapitalizations or rearrangements,
stock rights, rights to subscribe, voting rights, rights to receive securities,
options, warrants, calls, commitments, securities accounts, security
entitlements, and all new securities and other property which such Pledgor now
owns or may hereafter become entitled to receive on account of the foregoing or
with respect to any such company;

         TO HAVE AND TO HOLD the Pledged Collateral, together with all right,
title, interest, powers, privileges and preferences pertaining or incidental
thereto, unto the Agent, its successors and assigns, on behalf of the Secured
Parties, forever; subject, however, to the terms, covenants and conditions set
forth in this Agreement.

         2. Security for Obligations. The security interests and other rights
granted pursuant to Section 1 secure, and the Pledged Collateral is security
for, the prompt performance and payment in full in cash when due, whether at
stated maturity, by acceleration or otherwise of the Secured Obligations. The
Secured Obligations include, among other things, (i) Loans that may be advanced
by the Banks to such Pledgor, repaid and subsequently readvanced by the

                                       2
<PAGE>
Banks, (ii) obligations in respect of Letters of Credit issued for the account
of such Pledgor from time to time, and (iii) the guarantee obligations of such
Pledgor under Article XI of the Credit Agreement. Notwithstanding that the
balance of the Secured Obligations may at certain times be zero and that no
Letters of Credit may at certain times be outstanding, the Liens granted
hereunder to the Agent shall remain in full force and effect at all times and
with the same priority until the payment in full in cash of the Secured
Obligations, the termination of the Commitments and the expiration or
termination of all outstanding Letters of Credit.

         3. Delivery of Pledged Collateral. The Pledged Collateral and all
certificates, instruments and property representing or evidencing the Pledged
Collateral shall, within two Business Days of the later of the date of this
Agreement or a Pledgor's actual or constructive receipt thereof, be delivered to
and held by or on behalf of the Agent pursuant to this Agreement and shall be in
suitable form for transfer of ownership and possession by delivery, or shall be
accompanied by duly executed instruments of transfer or assignment in blank, all
in form and substance satisfactory to the Agent. The Agent shall have the right,
at any time in its discretion and without notice to any Pledgor, to transfer to
or to register in its name or any of its nominees, any or all of the Pledged
Collateral, subject only to the revocable rights of such Pledgor specified in
Section 6(a) hereof. In addition, the Agent shall have the right at any time to
exchange certificates or instruments representing or evidencing Pledged
Collateral for certificates or instruments of smaller or larger denominations.

         4. Representations, Warranties and Covenants. Each Pledgor represents,
warrants and covenants, to the Agent and the other Secured Parties, insofar as
the same relate to such Pledgor's assets, actions, statements and business, as
follows:

                  (a) Such Pledgor (i) is an entity duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
formation; (ii) is duly qualified and in good standing in every jurisdiction in
which the nature of its business makes such qualification necessary and where
the failure to so qualify has a reasonable likelihood of having a Material
Adverse Effect; (iii) has all requisite corporate power and authority and the
legal right to own, pledge, mortgage and operate its properties, and to conduct
its business as now or currently proposed to be conducted; (iv) is in compliance
with its certificate or articles of incorporation, by-laws and similar
organizational documents; (v) is not in default under any material agreement
such that there is a reasonable likelihood of such default having a Material
Adverse Effect; (vi) is in compliance (except to the extent any noncompliance
has no reasonable likelihood of having a Material Adverse Effect) with all Legal
Requirements; and (vii) together with the other Pledgors and Borrowers, forms
part of a group of companies that are closely related legally and economically,
each deriving benefits from the other, and the execution, delivery and
performance of this Agreement is conducive to the business interests of such
Pledgor and its pursuit of profits and continuity.

                  (b) Each Person listed on Schedule I hereto: (i) is an entity
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its organization; (ii) is duly qualified to do business and in
good standing in every jurisdiction in which the nature of the business it
conducts makes such qualification necessary or desirable; (iii) has all
requisite corporate power and authority and the legal right to own, pledge,
mortgage and operate its properties, and to conduct its business as now or
currently proposed to be conducted; (iv) is in

                                       3
<PAGE>
compliance with its certificate or articles of incorporation, by-laws and
similar organizational documents; and (v) to such Pledgor's best knowledge, is
in compliance (except to the extent any noncompliance has no reasonable
likelihood of having a Material Adverse Effect) with all Legal Requirements.

                  (c) The execution, delivery, and performance by such Pledgor
of this Agreement (i) are within such Pledgor's corporate power; (ii) have been
duly authorized by all necessary corporate action; (iii) do not contravene such
Pledgor's certificate or articles of incorporation or by-laws or other
organizational documents; (iv) do not result in or require the creation of any
Lien upon or with respect to any of its properties except for the Lien created
by this Agreement; and (v) do not conflict with or result in a breach of the
terms, conditions or provisions of, or cause a default under, any agreement,
instrument, franchise, license or concession to which such Pledgor is a party or
by which such Pledgor or any of its property is bound.

                  (d) No authorization or approval or other action by, and no
notice to or filing with, any Governmental Authority is required for the due
execution, delivery and performance by any Pledgor of this Agreement or for the
validity or enforceability thereof.

                  (e) This Agreement is a legal, valid and binding obligation of
such Pledgor enforceable against such Pledgor in accordance with its terms,
except as enforcement may be limited by applicable bankruptcy, insolvency or
similar laws relating to creditors' rights generally, as such laws would apply
in the event of bankruptcy insolvency or other similar occurrence with respect
to such Pledgor.

                  (f) There is no pending or, to the best knowledge of any
Pledgor, threatened action or proceeding affecting any Pledgor before or by any
Governmental Authority which has any reasonable likelihood of having a Material
Adverse Effect.

                  (g) Such Pledgor is not (i) a party to any contractual
obligation the performance of which either unconditionally or upon the happening
of an event, will result in the creation of a Lien on such Pledgor's property or
assets (other than in favor of the Secured Parties); or (ii) subject to any
charter or corporate restriction which has a reasonable likelihood of having a
Material Adverse Effect.

                  (h) The representations and warranties made or deemed to be
made by such Pledgor in Article VI of the Credit Agreement are true and correct,
and all statements made to the Secured Parties by or on behalf of such Pledgor
or any Obligor which is a Subsidiary of such Pledgor before, concurrently with
or after the execution of this Agreement with respect to the Pledged Collateral
are and will be true, correct, complete, valid and genuine in all material
respects. No statement contained in any certificate, schedule, list, financial
statement or other papers furnished to any Secured Party by or on behalf of such
Pledgor or any such Obligor contains (or will contain) any untrue statement of
material fact or omits (or will omit) to state a material fact necessary to make
the statements contained herein or therein not misleading.

                  (i) Except as otherwise indicated on Schedule I, the shares
described on Schedule I include all of the authorized, issued and outstanding
shares of capital stock of each of

                                       4
<PAGE>
the companies listed thereon and the rights to acquire shares in such
companies. Such Pledgor is the sole legal and equitable owner and holder of the
Pledged Shares indicated on Schedule I, which are free and clear of all Liens,
or rights or interests of any other Person, of every kind and nature except for
the Lien created by this Agreement. The shares of stock described in the first
sentence of this paragraph are duly authorized, validly issued, fully paid,
non-assessable, and free from any restriction on transfer, and none of such
shares has been issued or transferred in violation of the securities
registration, securities disclosure or similar laws of any jurisdiction to which
such issuance or transfer maybe subject. There are no options, warrants,
financing statements, calls or commitments of any character relating to the
Pledged Shares, nor are there any rights of first refusal, voting trusts, voting
agreements or similar agreements relating to the Pledged Shares. The pledge,
assignment and delivery of the Pledged Collateral pursuant to this Agreement
will create a valid first priority lien on and a first priority perfected
security interest in the Pledged Collateral and the proceeds thereof.
Appropriate financing statements will be filed in favor of the Agent in the
offices described on Schedule II hereto.

                  (j) When additional Pledged Collateral is delivered to the
Agent in accordance with Section 3, such Pledgor will be the legal and equitable
owner of such Pledged Collateral free and clear of all Liens, or rights or
interests of any other Person, of every kind and nature including any state or
federal tax liens, except for the Lien created by this Agreement; each share of
stock comprising such Pledged Collateral will have been duly authorized and
validly issued and will be fully paid and non-assessable and free from any
restriction on transfer; and such Pledgor will have legal title to such Pledged
Collateral and power to pledge, assign and deliver such Pledged Collateral in
the manner contemplated by this Agreement.

                  (k) Such Pledgor will (i) cause each issuer of shares of stock
comprising Pledged Collateral not to issue any stock or other securities in
addition to or in substitution for the shares of stock comprising Pledged
Collateral issued by such issuer, except to such Pledgor or another Pledgor and
subject to this Agreement, (ii) pledge hereunder, immediately upon its
acquisition (directly or indirectly) thereof, any and all additional shares of
stock or other securities of each issuer of Pledged Collateral, and (iii) pledge
hereunder, immediately upon its acquisition (directly or indirectly) thereof,
any and all shares of stock or other equity interest covered by Section 1(b)
hereof.

                  (l) Without the prior written consent of the Agent having been
first obtained, such Pledgor agrees that it (i) shall not sell, assign,
transfer, pledge, mortgage, hypothecate, dispose of or encumber, or grant any
option or warrant or Lien or right with respect to, or permit any Liens to arise
with respect to, the Pledged Collateral, any of its rights in or to the Pledged
Collateral and any portion thereof, except for the pledge thereof provided for
in this Agreement, and (ii) shall not permit any issuer of shares of stock
comprising Pledged Collateral to terminate its corporate existence, to be a
party to any merger or consolidation, or to sell, lease or dispose of all or
substantially all of its assets and properties in a single transaction or series
of related transactions, except as permitted by the Credit Agreement.

                  (m) Such Pledgor has and will defend the title to the Pledged
Collateral held by it and the Liens created by this Agreement against all claims
and demands of any Person at any time claiming the Pledged Collateral or any
interest therein and will maintain and preserve such Liens until the termination
of this Agreement.

                                       5

         5. Further Assurances.

                  (a) Each Pledgor agrees that, at any time and from time to
time, at the expense of such Pledgor, it will promptly execute and deliver all
further instruments and documents, and take all further action, that may be
necessary or desirable, or that the Agent may reasonably request, in order to
create, maintain, perfect and protect any Security interest, pledge, or
hypothecation granted or purported to be granted by this Agreement, to enable
the Agent to exercise and enforce its rights and remedies under this Agreement
with respect to any Pledged Collateral, and to assure the transferability by the
Agent and its successors of the Pledged Collateral. Each Pledgor agrees that it
shall notify the Agent in writing, at least two (2) weeks in advance of the date
that it changes the location of any office or place of business in the United
States, establishes any office or place of business in the United States, or
establishes its chief executive office in any other part of the world.

                  (b) Each Pledgor shall, with respect to any investment
property constituting Collateral (i) cause the Agent to have sole "control", as
defined in the UCC, of such investment property, together with all proceeds
thereof, and (ii) at the Agent's request from time to time, each Pledgor shall
instruct (and hereby instructs) any third party holding such Pledged Collateral
to obey only the instructions and entitlement orders of the Agent with respect
to such Pledged Collateral and any proceeds thereof. Except as the Agent may
otherwise permit in writing, no Pledgor shall have any right to cause the
withdrawal, application or transfer of any financial assets or security
entitlements with respect to the Pledged Collateral, and no Pledgor shall give
any instructions or entitlement orders with respect to them.

                  (c) Without limiting the generality of the foregoing
provisions, each Pledgor agrees that it will, upon obtaining any additional
shares of any issuer of the Pledged Collateral, shares or other equity interests
in entities described in Section 1(b) or any other securities constituting
Pledged Collateral, promptly (and in any event within five (5) Business Days)
deliver to the Agent (i) such shares, equity interests or other securities, (ii)
a duly executed but blank stock power in the form of Schedule III for each
certificate representing such additional Pledged Collateral, and (iii) a duly
executed Pledge Agreement Supplement in substantially the form of Schedule IV (a
"Pledge Agreement Supplement") or as may otherwise be reasonably required by the
Agent identifying the additional shares which are pledged pursuant to Section
1(b) hereof. Each Pledgor authorizes the Agent to attach each Pledge Agreement
Supplement to this Agreement and agrees that all shares, equity interests or
other securities listed on any Pledge Agreement Supplement delivered to the
Agent shall for all purposes constitute Pledged Collateral.

                  (d) Each Pledgor will cause to be paid before delinquency all
taxes, charges, liens and assessments at any time levied or assessed against the
Pledged Collateral held by it, or any part thereof, or against any Secured Party
for or on account of the Pledged Collateral or the interest created by this
Agreement, and will furnish the Agent with receipts showing payment of such
taxes and assessments at least five (5) days before the applicable default date
therefor.

                  (e) If the validity or priority of this Agreement or of any
rights, titles, security interests or other interests created or evidenced by
this Agreement shall be attacked, endangered or questioned or if any legal
proceedings are instituted with respect thereto, each Pledgor agrees

                                       6
<PAGE>
that it will take all necessary and proper steps for the defense of such legal
proceedings. The Agent is authorized and empowered to take such additional steps
as in its judgment and discretion may be necessary or proper for the defense of
any such legal proceedings or the protection of the validity or priority of this
Agreement and the rights, titles, security interests and other interests created
or evidenced by this Agreement, and the Secured Obligations include all expenses
so incurred of every kind and character.

                  (f) Regarding any proceedings relating to the Pledged
Collateral, or any portion thereof, the Agent may participate therein, and each
Pledgor agrees that it shall from time to time deliver to the Agent all
instruments reasonably requested by it to permit such participation. Each
Pledgor agrees that it shall, at its expense, diligently prosecute any such
proceedings and shall consult with the Agent, its attorneys and experts, and
cooperate with them in the carrying on or defense of any such proceedings.

         6.       Voting Rights; Dividends; Etc.

                  (a)      So long as no Default shall have occurred and be
continuing (and, in the case of clause (i) below, so long as written notice has
not been given by the Agent to the Company):

                  (i)      A Pledgor shall be entitled to exercise any and all
         voting and/or other consensual rights pertaining to its respective
         Pledged Collateral or any part thereof for any purpose consistent with
         the terms of this Agreement or the Credit Agreement; provided, however,
         that such Pledgor shall not exercise or refrain from exercising any
         such right with the primary intent of causing a Material Adverse
         Effect.

                  (ii)     A Pledgor shall be entitled to receive and retain any
         and all dividends paid in respect of the Pledged Collateral, other than
         any and all

                           (A)      dividends paid or payable other than in cash
                  in respect of, and instruments and other property received,
                  receivable or otherwise distributed in respect of, or in
                  exchange for, any Pledged Collateral,

                           (B)      dividends and other distributions paid or
                  payable in cash in respect of any Pledged Collateral in
                  connection with a partial or total liquidation or dissolution
                  or in connection with a return of capital, capital surplus or
                  paid-in-surplus, and

                           (C)      cash paid, payable or otherwise distributed
                  in redemption of, or in exchange for, any Pledged Collateral,

         all of which shall be, and all of which shall be forthwith delivered to
         the Agent to hold as Pledged Collateral and shall, if received by such
         Pledgor, be received in trust for the benefit of the Agent, be
         segregated from the other property or funds of such Pledgor, and be
         forthwith delivered to the Agent as Pledged Collateral in the same form
         as so received (with any necessary endorsement).

                                       7
<PAGE>
                  (iii)    The Agent shall execute and deliver (or cause to be
         executed and delivered) to a Pledgor all such proxies and other
         instruments as such Pledgor may reasonably request for the purpose of
         enabling such Pledgor to exercise the voting and other rights which it
         is entitled to exercise pursuant to clause (i) above and to receive the
         dividends which it is authorized to receive and retain pursuant to
         clause (ii) above.

         Regardless of a Pledgor's right described above to receive and retain
         certain rights and property, such rights and property nonetheless
         secure the repayment of the Secured Obligations and are a part of the
         Pledged Collateral.

         (b)      Upon the occurrence and during the continuation of a Default
and notice thereof to the Company:

                  (i)      All rights of a Pledgor to exercise the voting and
         other consensual rights which it would otherwise be entitled to
         exercise pursuant to Section 6(a)(i) and the obligations of the Agent
         under Section 6(a)(iii) shall cease, and all such rights shall
         thereupon become vested in the Agent who shall thereupon have the sole
         right to exercise such voting and other consensual rights;

                  (ii)     All rights of a Pledgor to receive the dividends
         which it would otherwise be authorized to receive and retain pursuant
         to Section 6(a)(ii) shall cease, and all such rights shall thereupon
         become vested in the Agent who shall thereupon have the sole right to
         receive and hold as Pledged Collateral such dividends; and

                  (iii)    All dividends which are received by a Pledgor
         contrary to the provisions of clause (ii) of this Section 6(b) shall be
         received in trust for the benefit of the Agent, shall be segregated
         from other funds of such Pledgor and shall be forthwith paid over to
         the Agent as Pledged Collateral in the same form as so received (with
         any necessary endorsement).

         (c)      In order to permit the Agent to exercise the voting and other
rights which it may be entitled to exercise pursuant to Section 6(b)(i), and to
receive all dividends and distributions which it may be entitled to receive
under Section 6(b)(ii), each Pledgor agrees that it shall, if necessary, upon
written notice from the Agent, from time to time execute and deliver to the
Agent appropriate dividend payment orders and other instruments as the Agent may
reasonably request. To this end, each Pledgor hereby irrevocably constitutes and
appoints the Agent the proxy and attorney-in-fact of each Pledgor, with full
power of substitution, to vote, and to act with respect to, any and all Pledged
Collateral that is securities standing in the name of such Pledgor or with
respect to which such Pledgor is entitled to vote and act, subject to the
understanding that such proxy may not be exercised unless an Event of Default
has occurred and is continuing. The proxy herein granted is coupled with an
interest, is irrevocable, and shall continue until payment in full in cash of
the Secured Obligations, the termination of the Commitments and the expiration
or termination of all outstanding Letters of Credit.

         7.       Agent Appointed Attorney-in-Fact. Each Pledgor hereby appoints
the Agent such Pledgor's true and lawful attorney-in-fact, with full authority
in the place and stead of such Pledgor and in the name of such Pledgor or
otherwise, from time to time in the Agent's

                                       8
<PAGE>
discretion, subject to Section 6, to take any action and to execute any document
or instrument which the Agent may reasonably deem necessary or desirable to
accomplish the purposes of this Agreement, including, without limitation, to
receive, endorse and collect all instruments made payable to such Pledgor
representing any dividend, interest payment or other distribution in respect of
the Pledged Collateral or any part thereof and to give full discharge for the
same. The Agent's liability, if any, otherwise arising under applicable law
shall be limited to amounts actually received as a result of the exercise of the
powers granted to it herein. No Agent or Bank, and no officer, director,
employee or agent of the Agent or any Bank, shall be responsible to any Pledgor
for any act or failure to act hereunder, except that any such Person shall be
responsible for its own gross negligence or willful misconduct.

         8.       Agent May Perform. The Agent is authorized to perform, or
cause performance of, any agreement contained herein in the event that a Pledgor
fails to timely perform the same, and the reasonable expenses of the Agent
incurred in connection therewith shall be payable by such Pledgor or by the
Company. The Agent is further authorized in its discretion to take any other
action, either on its own behalf or on behalf of a Pledgor (and as regards
actions taken on behalf of a Pledgor, this authorization is irrevocable and is
an agency coupled with an interest), as the Agent may elect, which the Agent may
deem necessary or appropriate to protect and preserve the rights, titles and
interests of the Agent hereunder. The powers conferred on the Agent pursuant to
this Agreement are conferred solely to protect the Secured Parties' interest in
the Pledged Collateral and shall not impose any duty or obligation on any
Secured Party to perform any of the powers herein conferred. No exercise of any
of the rights provided for in this Agreement constitute a retention of
collateral in satisfaction of indebtedness.

         9.       No Responsibility for Certain Actions; Indemnity. Neither the
Agent nor any other Secured Party shall have responsibility for (a) ascertaining
or taking action with respect to calls, conversions, exchanges, maturities,
tenders or other matters relative to any Pledged Collateral, whether or not the
Agent or any other Secured Party has or is deemed to have knowledge of such
matters, (b) taking any necessary steps to preserve any rights against any
Person with respect to any Pledged Collateral or (c) supervising, monitoring or
controlling any aspect of the character or condition of any of the Pledged
Collateral or any operations conducted in connection with it for the benefit of
a Pledgor or any other Person. Each Pledgor agrees to indemnify, defend and hold
Secured Parties, their respective shareholders, directors, officers, agents,
advisors and employees (collectively "Indemnified Parties") harmless from and
against any and all loss, liability, obligation, damage, penalty, judgment,
claim, deficiency, expense, action, suit, cost and disbursement of any kind or
nature whatsoever (including interest, penalties, attorneys' fees and amounts
paid in settlement), imposed on, incurred by or asserted against the Indemnified
Parties growing out of or resulting from this Agreement or any transaction or
event contemplated in it (except that such indemnity shall not be paid to any
Indemnified Party to the extent such loss, etc. directly results from the gross
negligence or willful misconduct of any of the Indemnified Parties).

         10.      Remedies upon Default. If any Event of Default shall have
occurred and be continuing:

                  (a) The Agent may exercise in respect of the Pledged
Collateral, in addition to other rights and remedies provided for herein or
otherwise available to it, all the rights and

                                       9
<PAGE>
remedies of a secured party in default under the New York UCC, and, subject to
applicable regulatory and legal requirements, the Agent may also, without notice
except as specified below, sell the Pledged Collateral or any part thereof in
one or more parcels at public or private sale, at any exchange, broker's board
or at any of the Agent's offices or elsewhere, for cash, on credit or for future
delivery, and upon such other terms as the Agent may deem commercially
reasonable. Upon consummation of any such sale, the Agent shall have the right
to assign, transfer and deliver to the purchaser or purchasers thereof the
Pledged Collateral so sold. Each such purchaser at any such sale shall hold the
property sold absolutely free from any claim or right on the part of any
Pledgor, and each Pledgor, for itself and for its successors, receivers,
trustees and assigns, and for any and all persons ever claiming any interest in
the Pledged Collateral, to the extent permitted by law, hereby WAIVES all rights
of extension, redemption, stay, valuation and appraisal, and any similar right
arising under the law of any country, which such Pledgor now has or may at any
time in the future have under any rule of law or statute now existing or
hereafter enacted. Each Pledgor agrees that, to the extent notice of sale shall
be required by law, at least 10 days' notice to such Pledgor of the time and
place of any public sale or the time after which any private sale is to be made
shall constitute reasonable notification. The Agent shall not be obligated to
make any sale of Pledged Collateral regardless of notice of sale having been
given. The Agent may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned. Each
Pledgor hereby WAIVES any claims against the Agent arising by reason of the fact
that the price at which any Pledged Collateral may have been sold at such a
private sale was less than the price which might have been obtained at a public
sale, even if the Agent accepts the first offer received and does not offer such
Pledged Collateral to more than one offeree. At any public sale made pursuant to
this Section 10, any Secured Party may bid for or purchase, free from any right
of redemption, stay or appraisal, and any similar right arising under the law of
any country, on the part of any Pledgor (all said rights being also hereby
WAIVED and released by each Pledgor), the Pledged Collateral or any part thereof
offered for sale and may make payment on account thereof by using any claim then
due and payable to it from any Obligor and/or any Pledgor as a credit against
the purchase price, and it may, upon compliance with the terms of sale, hold,
retain and dispose of such property without further accountability to any
Pledgor therefor. For purposes hereof, (i) a written agreement to purchase the
Pledged Collateral or any portion thereof shall be treated as a sale thereof,
(ii) the Agent shall be free to carry out such sale pursuant to such agreement
and (iii) no Pledgor shall be entitled to the return of the Pledged Collateral
or any portion thereof subject thereto, notwithstanding the fact that after the
Agent shall have entered into such an agreement all Events of Default shall have
been remedied and the Secured Obligations paid in full. As an alternative to
exercising the power of sale herein conferred upon it, the Agent may proceed by
a suit or suits at law or in equity to foreclose upon the Pledged Collateral and
to sell the Pledged Collateral or any portion thereof pursuant to a judgment or
decree of a court or courts having competent jurisdiction or pursuant to a
proceeding by a court-appointed receiver. Any sale pursuant to the provisions of
this Section 10 shall be deemed to conform to the commercially reasonable
standards as provided in the New York UCC. Each Pledgor covenants and agrees
that it will execute and deliver such documents and take such other action as
the Agent deems necessary or advisable in order that any such sale may be made
in compliance with applicable law.

                                       10
<PAGE>
                  (b) The Agent shall have all the rights of a secured party
after default under the New York UCC and in conjunction with, in addition to or
in substitution for those rights and remedies:

                           (i) it shall not be necessary that the Pledged
                  Collateral or any part thereof be present at the location of
                  any sale pursuant to the provisions of this Section 10;

                           (ii) to the extent the sale of Pledged Collateral is
                  insufficient to satisfy the Secured Obligations, the Borrowers
                  shall remain liable for any deficiency;

                           (iii) the sale by the Agent of less than the whole of
                  the Pledged Collateral shall not exhaust the rights of the
                  Agent hereunder, and the Agent is specifically empowered to
                  make successive sale or sales hereunder until the whole of the
                  Pledged Collateral shall be sold; and, if the proceeds of such
                  sale of less than the whole of the Pledged Collateral shall be
                  less than the aggregate of the Secured Obligations, this
                  Agreement and the security interest created hereby shall
                  remain in full force and effect as to the unsold portion of
                  the Pledged Collateral just as though no sale had been made;

                           (iv) in the event any sale hereunder is not completed
                  or is defective in the opinion of the Agent, such sale shall
                  not exhaust the rights of the Agent hereunder and the Agent
                  shall have the right to cause a subsequent sale or sales to be
                  made hereunder; and

                           (v) demand of performance, advertisement and presence
                  of property at sale are hereby WAIVED and the Agent is hereby
                  authorized to sell hereunder any financial asset it may hold
                  as security for the Secured Obligations. All demands and
                  presentments of any kind or nature are expressly, WAIVED by
                  each Pledgor. Each Pledgor hereby WAIVES the right to require
                  the Agent to pursue any other remedy for the benefit of such
                  Pledgor and agrees that Secured Party may proceed against any
                  Person for the amount of the Obligations owed to the Agent
                  without taking any action against any other Person and without
                  selling or otherwise proceeding against or applying any of the
                  Pledged Collateral in the Agent's possession.

                  (c) Each Pledgor recognizes that, by reason of certain
prohibitions contained in the Securities Act of 1933 and applicable state
securities laws, the Agent may be compelled, with respect to any sale of all or
any part of the Pledged Collateral, to limit purchasers to those who will agree,
among other things, to acquire such securities for their own account, for
investment, and not with a view to the distribution or resale thereof. Each
Pledgor acknowledges and agrees that any such sale may result in prices and
other terms less favorable to the seller than if such sale were a public sale
without such restrictions and agrees that such circumstances shall not be a
factor in determining whether such sale has been made in a commercially
reasonable manner. The Agent shall be under no obligation to delay the sale of
any of the Pledged Collateral for the period of time necessary to permit any
Pledgor to register such securities for

                                       11
<PAGE>
public sale under the Securities Act of 1933, or under applicable state
securities laws, even if a Pledgor would agree to do so.

                  (d) If the Agent determines to exercise its right to sell any
or all of the Pledged Collateral, upon written request, each Pledgor shall, and
shall cause each of its direct Subsidiaries to, from time to time, furnish to
the Agent all such information as the Agent may reasonably request in order to
determine the number of shares and other instruments included in the Pledged
Collateral which may be sold by the Agent as exempt transactions under the
Securities Act of 1933 and rules of the Securities and Exchange Commission
thereunder, as the same are from time to time in effect.

                  (e) Any cash held by the Agent as Pledged Collateral and all
cash proceeds received by the Agent in respect of any sale of, collection from,
or other realization upon all or any part of the Pledged Collateral shall be
applied by the Agent (unless otherwise required by law):

                  First, to the payment of the costs and expenses of retaking,
         holding, preparing for sale, or selling the Pledged Collateral or any
         portion thereof, including all expenses (including, without limitation,
         any legal fees and disbursements and the allocated cost of in-house
         counsel), liabilities and advances made or incurred by the Agent in
         connection therewith;

                  Next, to the Agent and the other Secured Parties in partial
         payment of the Secured Obligations; and

                  Finally, after payment in full in cash of all Secured
         Obligations, termination of the Commitments and expiration or
         termination of all outstanding Letters of Credit, to the payment to
         applicable Pledgor, or its successors or assigns, or to whomsoever may
         be lawfully entitled to receive the same or as a court of competent
         jurisdiction may direct, of any surplus then remaining from such cash
         and cash proceeds.

                  (f) All remedies herein expressly provided for are cumulative
of any and all other remedies existing at law or in equity and are cumulative of
any and all other remedies provided for in any other instrument securing the
payment of the Obligations, or any part thereof, or otherwise benefiting the
Secured Parties, and the resort to any remedy provided for hereunder or under
any such other instrument or provided for by law shall not prevent the
concurrent or subsequent employment of any other appropriate remedy or remedies.

                  (g) The Secured Parties may resort to any security given by
this Agreement or to any other security now existing or hereafter given to
secure the payment of the Obligations, in whole or in part, and in such portions
and in such order as may seem best to such Secured Party in its sole and
uncontrolled discretion, and any such action shall not in anywise be considered
as a waiver of any of the rights, benefits or security interests evidenced by
this Agreement.

         11. Expenses. Each Pledgor agrees that it will upon demand pay to the
Agent the amount of any and all reasonable costs, disbursements and expenses of
every character, including without limitation the reasonable fees and expenses
of its counsel (including the

                                       12
<PAGE>
reasonable allocated cost of inhouse counsel), subject to the limitations
expressed in Section 13.5 of the Credit Agreement, and of any experts, incurred
or expended by the Agent from time to time in connection with: (a) the
preparation, negotiation, documentation, closing, renewal, revision,
modification, renegotiation or review of this Agreement; (b) the custody or
preservation of, or the sale of, collection from, or other realization upon, any
of the Pledged Collateral, (c) the exercise or enforcement of any of the rights
of the Agent or any other Secured Party hereunder, or (d) the failure by a
Pledgor to perform or observe any of the provisions hereof.

         12. Amendments, Etc. No amendment or waiver of any provision of this
Agreement, nor consent to any departure by a Pledgor herefrom, shall in any
event be effective unless the same shall be in writing and signed by the Agent
and, in the case of amendment, by the Company and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given and to the extent therein specified. The Agent may waive any
default without waiving any other prior or subsequent default, and the Agent may
remedy any default, without waiving the default remedied. The failure by the
Agent to exercise any right, power or remedy upon any default shall not be
construed as a waiver of such default or as a waiver of the right to exercise
any such right, power or remedy at a later date. No single or partial exercise
by the Agent of any right, power or remedy hereunder shall exhaust the same or
shall preclude any other or further exercise thereof, and every such right,
power or remedy hereunder may be exercised at any time and from time to time. No
notice to nor demand on a Pledgor in any case shall of itself entitle a Pledgor
to any other or further notice or demand in similar or other circumstances.
Acceptance by the Agent of any payment in an amount less than the amount then
due on the Secured Obligations shall be deemed an acceptance on account only and
shall not in any way affect the existence of a default hereunder. No waiver,
release, consent by Agent pursuant to this Agreement shall affect or impair the
rights of a Secured Party against any third party, except to the extent
specifically agreed to by the Secured Party in such writing.

         13. Address for Notices. Except as otherwise provided herein, all
notices, requests and other communications provided for hereunder shall be in
writing and given as provided in the Credit Agreement, and any notice to a
Pledgor or may be delivered to the Company.

         14. Continuing Security Interest. This Agreement shall create a
continuing security interest in the Pledged Collateral and shall (a) remain in
full force and effect until payment in full in cash (after the termination of
the Commitments and the expiration or termination of all outstanding Letters of
Credit) of the Secured Obligations; (b) continue to be effective if at any time
payment and performance of the Secured Obligations is, pursuant to applicable
law, rescinded or reduced in amount, or must otherwise be restored by the Agent
or any other Secured Party; (c) be binding upon each Pledgor, its successors and
assigns, and any trustee, receiver, or conservator of a Pledgor, and any
successors in interest of a Pledgor in and to all or any part of the Pledged
Collateral; and (d) inure, together with the rights and remedies of the Agent
hereunder, to the benefit of the Agent, the other Secured Parties and their
respective successors, transferees and assigns. Without limiting the generality
of the foregoing clause (d), the Agent and/or any Bank may assign or otherwise
transfer its rights and obligations under the Credit Agreement to any other
Person or entity, and such other Person or entity shall thereupon become vested
with all the benefits in respect thereof granted to such Bank herein or
otherwise, all as provided in, and to the extent set forth in, the Credit
Agreement. Upon the payment in full in cash (after the termination of the
Commitments and the expiration or termination of all

                                       13
<PAGE>
outstanding Letters of Credit) of the Secured Obligations, the Company shall be
entitled to the return, upon its request and at its expense, of such of the
Pledged Collateral as shall not have been sold or otherwise applied pursuant to
the terms hereof.

         15. Security Interest Absolute. All rights and security interests of
the Secured Parties hereunder, and all obligations of a Pledgor hereunder, shall
be absolute and unconditional irrespective of

                  (a) any lack of validity or enforceability of the Credit
Agreement, any other Credit Document, or any other agreement or instrument
relating thereto;

                  (b) any change in the time, manner or place of payment of, or
in any other term of, all or any of the Secured Obligations (including, without
limitation, the possible extension of the Commitment Termination Date and
increase of the amount of the Commitments all on the terms and conditions set
forth in the Credit Agreement), or any other amendment, renewal or waiver of or
any consent to any departure from the Credit Agreement or any other Credit
Document;

                  (c) any exchange, release or non-perfection of any other
collateral, or any release or amendment or waiver of or consent to departure
from any guaranty, for all or any of the Obligations;

                  (d) any indulgence, moratorium or release granted by any
Secured Party, including but not limited to (i) any renewal, extension or
modification which a Secured Party may grant with respect to the Obligations,
(ii) any surrender, compromise, release, renewal, extension, exchange or
substitution which a Secured Party may grant in respect of any item securing the
Obligations, or any part thereof or any interest therein, or (iii) any release
or indulgence granted to any endorser, guarantor or surety of the Obligations;
or

                  (e) any other circumstance which might otherwise constitute a
defense available to, or a discharge of, a Pledgor or a third party pledgor.

         16. Reserved.

         17. Right of Set-off.

                  (a) Upon the occurrence and during the continuation of any
Event of Default under the Credit Agreement, each Bank is hereby authorized at
any time and from time to time, to the fullest extent permitted by law, to
set-off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing
by such Bank to or for the credit or the account of a Pledgor against any and
all of the Secured Obligations, irrespective of whether or not such Bank shall
have made any demand under this Agreement and although such Secured Obligations
may be contingent and unmatured. Each Bank which sets-off pursuant to this
Section 17(a) shall give prompt notice to the Company following the occurrence
thereof; provided that the failure to give such notice shall not affect the
validity of the set-off.

                                       14
<PAGE>
                  (b) Any payment obtained by any Bank pursuant to Section 17(a)
(or in any other manner directly from a Pledgor) shall be remitted to the Agent
and distributed among the Secured Parties in accordance with the provisions of
Section 10(e).

         18. Severability. If for any reason any provision or provisions hereof
are determined to be invalid and contrary to any existing or future law, such
invalidity shall not impair the operation of or affect those portions of this
Agreement which are valid. Each waiver in this Agreement is subject to the
overriding and controlling rule that it shall be effective only if and to the
extent that (a) it is not prohibited by applicable law and (b) applicable law
neither provides for nor allows any material sanctions to be imposed against the
Secured Parties for having bargained for and obtained it.

         19. Waiver of Jury Trial. EACH PLEDGOR HEREBY WAIVES AND AGREES TO
WAIVE ANY RIGHT IT MAY HAVE TO A JURY TRIAL IN CONNECTION WITH ANY ACTION, SUIT
OR PROCEEDING ARISING OUT OF OR RELATED IN ANY WAY TO THIS AGREEMENT OR ANY
OTHER CREDIT DOCUMENT.

         20. Governing Law; Jurisdiction.

                  (a) THIS AGREEMENT AND EACH ISSUE ARISING HEREUNDER SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK
(EXCLUDING ITS CONFLICTS OF LAWS PRINCIPLES), EXCEPT TO THE EXTENT PROVIDED IN
SECTION 13.14(b) OF THE CREDIT AGREEMENT AND TO THE EXTENT THAT THE FEDERAL LAWS
OF THE UNITED STATES OF AMERICA MAY OTHERWISE APPLY. THE PARTIES AGREE THAT THIS
CHOICE OF NEW YORK LAW HAS BEEN MADE PURSUANT TO SECTION 5-1401 OF THE GENERAL
OBLIGATIONS LAW OF THE STATE OF NEW YORK. Unless otherwise defined herein or in
the Credit Agreement, terms defined in Articles 8 and 9 of the New York UCC are
used herein as therein defined.

                  (b) Except as otherwise provided in Section 20(d), any legal
action or proceeding with respect to this Agreement may be brought in the courts
of the State of New York located in the Borough of Manhattan or of the United
States of America for the Southern District of New York, and by execution and
delivery of this Agreement, each Pledgor hereby consents, for itself and in
respect of its property, to the jurisdiction of the aforesaid courts. Each
Pledgor hereby irrevocably waives any objection, including without limitation,
any objection to the laying of venue or based on the grounds of forum non
conveniens, which it may now or hereafter have to the bringing of any action or
proceeding in such jurisdiction in respect of this Agreement, any other Credit
Document, or any document related to this Agreement or any other Credit
Document. Each Pledgor agrees that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in any other jurisdictions by
suit on the judgment or in any other manner provided by law.

                  (c) Each Pledgor has irrevocably appointed CT Corporation
System, with an office at 111 Eighth Ave., New York, New York, 10011 (the
"Process Agent"), as its agent to receive on behalf of such Pledgor and its
property service of copies of the summons and complaint and any other process
which may be served in any action or proceeding arising out of

                                       15
<PAGE>
or relating to this Agreement. Such service may be made by mailing or delivering
a copy of such process to a Pledgor in care of the Process Agent at the Process
Agent's above address, and each Pledgor hereby irrevocably authorizes and
directs the Process Agent to accept such service on its behalf. As an
alternative method of service, each Pledgor also irrevocably consents to the
service of any and all process in any such action or proceeding by the mailing
of copies of such process to such Pledgor at the address for the Company
specified in the Credit Agreement. Process may be served in English, and each
Pledgor irrevocably waives any right accruing to it under the Hague Convention
on the Service Abroad of Judicial and Extrajudicial Documents, the Hague
Convention on the Taking of Evidence Abroad in Civil or Commercial Matters, or
any other applicable law (including without limitation Panamanian law), and any
similar treaty regarding the service of process or the collection of evidence.
Any process and documents to be sent to the other party containing languages
other than English shall be sent with English translations certified by the
sender, and the sending party shall bear the translation costs.

                  (d) Nothing in this Section 20 shall affect the right of the
Agent or any other Secured Party to serve legal process in any other manner
permitted by law or affect the right of the Agent or any other Secured Party to
bring any action or proceeding against a Pledgor in the courts of any other
jurisdictions.

                  (e) To the extent a Pledgor has or hereafter may acquire any
immunity from jurisdiction of any court or from any legal process (whether
through service or notice, attachment prior to judgment, attachment in aid of
execution, execution or otherwise) with respect to itself or its property, such
Pledgor hereby irrevocably waives such immunity in respect of its obligations
under this Agreement.

                  (f) THIS AGREEMENT TOGETHER WITH THE OTHER CREDIT DOCUMENTS
EMBODIES THE ENTIRE AGREEMENT AND UNDERSTANDING AMONG THE PARTIES WITH RESPECT
TO ITS SUBJECT MATTER AND SUPERSEDES ALL PRIOR OR CONTEMPORANEOUS AGREEMENTS AND
UNDERSTANDINGS OF SUCH PERSONS, VERBAL OR WRITTEN, RELATING TO SUCH SUBJECT
MATTER.

         21. Counterpart. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original for all purposes;
but such counterparts shall be deemed to constitute but one and the same
instrument.

         22. Waiver of Subrogation. Each Pledgor expressly WAIVES any and all
rights of subrogation, reimbursement and contribution (contractual, statutory or
otherwise) against the Secured Parties, individually and collectively, including
without limitation, any claim or right of subrogation under the Bankruptcy Code
(Title 11 of the U.S. Code) or any successor statute, arising from the existence
or performance of this Agreement and each Pledgor irrevocably WAIVES any right
to enforce any remedy which the Secured Parties, or any one or more of them, now
have or may hereafter have against Borrowers and WAIVES any benefit of, and any
right to participate in, any security now or hereafter held by the Secured
Parties, or any one or more of them, until the Secured Obligations have been
paid and performed in full (after the termination of the Commitments and the
expiration or termination of all outstanding Letters of Credit).

                                       16
<PAGE>
         23. Subordination. Each Pledgor hereby expressly covenants and agrees
for the benefit of the Secured Parties that all obligations and liabilities of
the other Borrowers to such Pledgor of whatsoever description (including,
without limitation, all intercompany receivables of such Pledgor from each of
the other Borrowers) shall be subordinated and junior in right of payment to the
Secured Obligations. Following the occurrence of an Event of Default, all
indebtedness of the other Borrowers to such Pledgor shall, if the Agent shall so
request, be collected and received by such Pledgor as trustee for the Secured
Parties and paid over to the Secured Parties, or any one or more of them, as the
case may be, on account of the Secured Obligations, but without reducing or
affecting in any manner the obligations of such Pledgor under this Agreement.

                       FORM OF MUSKETEER PLEDGE AGREEMENT

                                PLEDGE AGREEMENT

         This PLEDGE AGREEMENT (this "Agreement"), dated as of June 14, 2002, is
made and entered into by MUSKETEER OIL B.V., a Netherlands limited liability
company (the "Company"), in favor of CREDIT LYONNAIS NEW YORK BRANCH, as agent
(in such capacity, the "Agent") under the Credit Agreement described below.

1.       PRELIMINARY STATEMENTS.

         1.       Willbros Group, Inc., a Republic of Panama corporation ("WGI")
and the Designated Subsidiaries from time to time (collectively, the
"Obligors"); certain financial institutions from time to time (the "Banks");
Credit Lyonnais New York Branch, as a Bank, as Issuing Bank, as administrative
agent for the Banks (in such capacity, the "Agent"), and as Lead Arranger and
Joint Book Runner; CIBC World Markets Corp., as Joint Lead Arranger and Joint
Book Runner; and Canadian Imperial Bank of Commerce, as Syndication Agent, are
parties to the Credit Agreement dated as of June 14, 2002 (such Credit
Agreement, as amended, restated, supplemented or otherwise modified from time to
time, being hereinafter referred to as the "Credit Agreement"). Unless otherwise
defined herein, terms defined in the Credit Agreement are used herein as therein
defined. "New York UCC" means, at any time, the Uniform Commercial Code in
effect in the State of New York at that time.

         2.       Pursuant to the Credit Agreement, the Banks have agreed to
make available to each Obligor, as a Borrower, a revolving credit facility for
loans and letters of credit, and each Obligor has guaranteed the obligations of
each Borrower pursuant to Section XI of the Credit Agreement.

         3.       The Company is an indirect Subsidiary of WGI and an affiliate
of all of the Obligors, and the Company will derive substantial benefit from
each extension of credit to the Obligors by the Banks under the Credit
Agreement.

         4.       The obligation of the Banks to make the Loans and to issue or
participate in the Letters of Credit is conditioned upon, among other things,
the execution and delivery by the Company of this Agreement.

2.       AGREEMENTS.

         In consideration of the premises and in order to induce the Banks to
enter into the Credit Agreement and make the Loans and issue or participate in
the Letters of Credit, and for other good and valuable consideration, the
receipt and sufficiency of which are acknowledged and confessed by the parties,
the Company agrees with the Agent, for the benefit of the Agent and the Banks
(the Agent and the Banks collectively, the "Secured Parties"), as follows:
<PAGE>
         1.       Pledge. In order to secure the prompt and unconditional
payment of the obligations referred to in Section 2 and the performance of the
obligations, covenants, agreements and undertakings described in this Agreement,
the Company hereby TRANSFERS, GRANTS, BARGAINS, SELLS, CONVEYS, HYPOTHECATES,
SETS OVER, DELIVERS AND PLEDGES to the Agent, on behalf of the Secured Parties,
and GRANTS to the Agent, on behalf of the Secured Parties, a security interest
in, all of the Company's remedies, powers, privileges, rights, titles and
interests of every kind and character now owned or hereafter acquired, created
or arising in and to the following (the "Pledged Collateral"):

                  (a)      the Pledged Shares (as defined below);

                  (b)      all shares of capital stock, general and limited
partnership interests, trust interests, joint venture interests, ownership
rights arising under the law of any jurisdiction, and any evidence of the
foregoing, together with any property and rights derivative thereof, acquired,
received or owned by the Company of any Person which, on or after the date of
this Agreement, is or becomes, as a result of any occurrence, a direct
Subsidiary of the Company;

                  (c)      all certificates and similar evidence of ownership
representing the Pledged Shares;

                  (d)      all cash dividends, stock dividends, cash,
instruments and other property or proceeds from time to time received,
receivable or otherwise distributed in respect of or in exchange for any or all
of the Pledged Shares or the shares or interests acquired, received or owned
under Section 1(b); and

                  (e)      all additions to and substitutions for any of the
foregoing and all products and proceeds of any of the Pledged Collateral,
together with all renewals and replacements of any of the Pledged Collateral,
all accounts, accounts receivable, instruments, notes, chattel paper, documents
(including all documents of title), books, records, contract rights and general
intangibles arising in connection with any of the Pledged Collateral.

         "Pledged Shares" means all shares described in Schedule I, as amended
from time to time, together with all rights, contingent or otherwise, of the
Company to acquire shares in the entities or organizations represented by the
shares described in Schedule I, as amended from time to time, or in any
Borrower, all rights to receive cash dividends, stock dividends, distributions
upon redemption or liquidation, distributions as a result of split-ups,
recapitalizations or rearrangements, stock rights, rights to subscribe, voting
rights, rights to receive securities, options, warrants, calls, commitments,
securities accounts, security entitlements, and all new securities and other
property which the Company now owns or may hereafter become entitled to receive
on account of the foregoing or with respect to any such company;

         TO HAVE AND TO HOLD the Pledged Collateral, together with all right,
title, interest, powers, privileges and preferences pertaining or incidental
thereto, unto the Agent, its successors and assigns, on behalf of the Secured
Parties, forever; subject, however, to the terms, covenants and conditions set
forth in this Agreement.

         2.       Security for Obligations. The security interests and other
rights granted pursuant to Section 1 secure, and the Pledged Collateral is
security for, the prompt performance and

                                       2
<PAGE>
payment in full in cash when due, whether at stated maturity, by acceleration or
otherwise of the Secured Obligations; provided, however, that to the extent that
in a legal proceeding brought within the applicable limitations period it is
determined by the final, nonappealable order of a court having jurisdiction over
the issue and the applicable parties that the Company received less than a
reasonably equivalent value in exchange for the Company's incurrence of its
obligations under this Agreement, then and only then is the Secured Obligations,
for the purposes of this Agreement only, limited in amount to the Guaranteed
Debt that would have applied to the Company had it been a direct party to the
Credit Agreement). The Credit Agreement guarantees, among other things, the
prompt performance and payment in full of the Obligations. The Secured
Obligations include, among other things, revolving credit pursuant to which
loans may be made, repaid and reborrowed, and letters of credit may be issued
from time to time. Notwithstanding that the balance of the revolving credit may
at certain times be zero and that no Letters of Credit may at certain times be
outstanding, the Liens granted hereunder to the Agent shall remain in full force
and effect at all times and with the same priority until the payment in full in
cash of the Secured Obligations, the termination of the Commitments and the
expiration or termination of all outstanding Letters of Credit.

         3.       Delivery of Pledged Collateral. The Pledged Collateral and all
certificates, instruments and property representing or evidencing the Pledged
Collateral shall, within two Business Days of the Company's actual or
constructive receipt thereof, be delivered to and held by or on behalf of the
Agent pursuant to this Agreement and shall be in suitable form for transfer of
ownership and possession by delivery, or shall be accompanied by duly executed
instruments of transfer or assignment in blank, all in form and substance
satisfactory to the Agent. The Agent shall have the right, at any time in its
discretion and without notice to the Company, to transfer to or to register in
its name or any of its nominees, any or all of the Pledged Collateral, subject
only to the revocable rights specified in Section 6(a). In addition, the Agent
shall have the right at any time to exchange certificates or instruments
representing or evidencing Pledged Collateral for certificates or instruments of
smaller or larger denominations.

         4.       Representations, Warranties and Covenants. The Company
represents, warrants and covenants to the Agent and the other Secured Parties as
follows:

                  (a)      The Company (i) is a private limited liability
company (besloten vennootschap) duly organized, validly existing and in good

corporate power and authority and the legal right to own, pledge, mortgage and
operate its properties, and to conduct its business as now or currently proposed

of a group of companies that are closely related legally and economically, each

this Agreement is conducive to the business interests of the Company and its
pursuit of profits and continuity.

                  (b)      Each Person listed on Schedule I or described in
Section 1(b): (i) is an entity duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization; (ii) is duly
qualified to do business and in good standing in every jurisdiction in which the

with its articles of association and similar organizational documents; and (v)

                  (c)      The execution, delivery, and performance by the
Company of this Agreement (i) are within the Company's corporate power; (ii)

with or result in a breach of the terms, conditions or provisions of, or cause a

which the Company is a party or by which the Company or any of its property is
bound.

                  (d)      No authorization or approval or other action by, and
no notice to or filing with, any Governmental Authority is required for the due
execution, delivery and performance by the Company of this Agreement or for the
validity or enforceability thereof.

                  (e)      This Agreement is a legal, valid and binding
obligation of the Company enforceable against the Company in accordance with its
terms, except as enforcement may be limited by applicable bankruptcy, insolvency
or similar laws relating to creditors' rights generally, as such laws would
apply in the event of bankruptcy, insolvency or other similar occurrence with
respect to the Company.

                  (f)      There is no pending or, to the best knowledge of the
Company, threatened action or proceeding affecting the Company before or by any
Governmental Authority which has any reasonable likelihood of having a Material
Adverse Effect.

                  (g)      The Company is not (i) a party to any contractual
obligation the performance of which either unconditionally or upon the happening
of an event, will result in the creation of a Lien on the Company's property or
assets (other than in favor of the Secured Parties); or (ii) subject to any
charter or corporate restriction which has a reasonable likelihood of having a
Material Adverse Effect.

                  (h)      The representations and warranties made by the
Borrowers in Article V of the Credit Agreement are true and correct, and all
information supplied to the Secured Parties, and all statements made to the
Secured Parties by or on behalf of any Borrower or the Company before,
concurrently with or after the Company's execution of this Agreement with
respect to the Pledged Collateral are and will be true, correct, complete, valid
and genuine in all material respects. No statement contained in any certificate,
schedule, list, financial statement or other papers furnished to any Secured
Party by or on behalf of any Borrower or the Company contains

                                       4
<PAGE>
(or will contain) any untrue statement of material fact or omits (or will omit)
to state a material fact necessary to make the statements contained herein or
therein not misleading.

                  (i)      The shares described on Schedule I include all of the
authorized, issued and outstanding shares of capital stock of each of the
companies listed thereon and the rights to acquire shares in such companies. The
companies and other entities listed on Schedule I constitute all of the Obligors
and all of the Material Subsidiaries in which the Company has a direct ownership
interest. The Company is the sole legal and equitable owner and holder of the
Pledged Shares, which are free and clear of all Liens, or rights or interests of
any other Person, of every kind and nature except for the Lien created by this
Agreement. The shares of stock described in the first sentence of this paragraph
are duly authorized, validly issued, fully paid, non-assessable, and free from
any restriction on transfer, and none of such shares has been issued or
transferred in violation of the securities registration, securities disclosure
or similar laws of any jurisdiction to which such issuance or transfer may be
subject. There are no options, warrants, financing statements, calls or
commitments of any character relating to the Pledged Shares, nor are there any
rights of first refusal, voting trusts, voting agreements or similar agreements
relating to the Pledged Shares. The pledge, assignment and delivery of the
Pledged Collateral pursuant to this Agreement will create a valid first priority
lien on and a first priority perfected security interest in the Pledged
Collateral and the proceeds thereof. An appropriate financing statement will be
filed in favor of the Agent in the Office of the Mayor of the District of
Columbia, U.S.A. The Company maintains no office or place of business in the
United States of America, in Canada or in any other part of the world, other
than its registered office in The Netherlands.

                  (j)      When additional Pledged Collateral is delivered to
the Agent in accordance with Section 3, the Company will be the legal and
equitable owner of such Pledged Collateral free and clear of all Liens, or
rights or interests of any other Person, of every kind and nature including any
state or federal tax liens, except for the Lien created by this Agreement; each
share of stock comprising such Pledged Collateral will have been duly authorized
and validly issued and will be fully paid and non-assessable and free from any
restriction on transfer; and the Company will have legal title to such Pledged
Collateral and power to pledge, assign and deliver such Pledged Collateral in
the manner contemplated by this Agreement.

                  (k)      The Company agrees that it will (i) cause each issuer
of shares of stock comprising Pledged Collateral not to issue any stock or other
securities in addition to or in substitution for the shares of stock comprising
Pledged Collateral issued by such issuer, except to the Company, (ii) pledge
hereunder, immediately upon its acquisition (directly or indirectly) thereof,
any and all additional shares of stock or other securities of each issuer of
Pledged Collateral, and (iii) pledge hereunder, immediately upon its acquisition
(directly or indirectly) thereof, any and all shares of stock covered by Section
1(b).

                  (l)      Without the prior written consent of the Agent having
been first obtained, the Company (i) shall not sell, assign, transfer, pledge,
mortgage, hypothecate, dispose of or encumber, or grant any option or warrant or
Lien or right with respect to, or permit any Liens to arise with respect to, the
Pledged Collateral, any of its rights in or to the Pledged Collateral and any
portion thereof, except for the pledge thereof provided for in this Agreement,
and (ii) shall not permit any issuer of shares of stock comprising Pledged
Collateral to terminate its corporate

                                       5
<PAGE>
existence, to be a party to any merger or consolidation, or to sell, lease or
dispose of all or substantially all of its assets and properties in a single
transaction or series of related transactions, except as permitted by the Credit
Agreement.

                  (m)      The Company has and will defend the title to the
Pledged Collateral and the Liens created by this Agreement against all claims
and demands of any Person at any time claiming the Pledged Collateral or any
interest therein and will maintain and preserve such Liens until the termination
of this Agreement.

         5.       Further Assurances.

                  (a)      The Company agrees that, at any time and from time to
time, at the expense of the Company, the Company will promptly execute and
deliver all further instruments and documents, and take all further action, that
may be necessary or desirable, or that the Agent may reasonably request, in
order to create, maintain, perfect and protect any security interest, pledge, or
hypothecation granted or purported to be granted by this Agreement, to enable
the Agent to exercise and enforce its rights and remedies under this Agreement
with respect to any Pledged Collateral, and to assure the transferability by the
Agent and its successors of the Pledged Collateral. The Company shall notify the
Agent in writing, at least two (2) weeks in advance of the date that it
establishes any office or place of business in the United States, or establishes
its chief executive office in any other part of the world, of its intent to
establish such office.

                  (b)      Where all or any part of any jurisdiction's enactment
of the 1994 revisions to Article 8 of the Uniform Commercial Code applies with
respect to a portion of the Pledged Collateral, (i) the Company shall cause the
Agent to have sole "control", as defined therein, of such Pledged Collateral
that comprises investment property, together with all proceeds thereof, and (ii)
at the Agent's request from time to time, the Company shall instruct (and hereby
instructs) any third party holding such Pledged Collateral to obey only the
instructions and entitlement orders of the Agent with respect to such Pledged
Collateral and any proceeds thereof. Except as the Agent may otherwise permit in
writing, the Company shall have no right to cause the withdrawal, application or
transfer of any financial assets or security entitlements with respect to the
Pledged Collateral, and the Company shall not give any instructions or
entitlement orders with respect to them.

                  (c)      Without limiting the foregoing, the Company further
agrees that it will, upon obtaining any additional shares of any issuer of the
Pledged Collateral or shares or other equity interests in entities described in
Section 1(b) or any other securities constituting Pledged Collateral, promptly
(and in any event within five (5) Business Days) deliver to the Agent (i) such
shares, (ii) a duly executed but blank stock power in the form of Schedule II
for each certificate representing such additional Pledged Collateral, and (iii)
a duly executed Pledge Agreement Supplement in substantially the form of
Schedule III (a "Pledge Agreement Supplement") or as may otherwise be reasonably
required by the Agent identifying the additional shares which are pledged
pursuant to Section 1(b). The Company authorizes the Agent to attach each Pledge
Agreement Supplement to this Agreement and agrees that all shares listed on any
Pledge Agreement Supplement delivered to the Agent shall for all purposes
constitute Pledged Collateral.

                                       6
<PAGE>
                  (d)      The Company will cause to be paid before delinquency
all taxes, charges, liens and assessments at any time levied or assessed against
the Pledged Collateral, or any part thereof, or against any Secured Party for or
on account of the Pledged Collateral or the interest created by this Agreement,
and will furnish the Agent with receipts showing payment of such taxes and
assessments at least five days before the applicable default date therefor.

                  (e)      If the validity or priority of this Agreement or of
any rights, titles, security interests or other interests created or evidenced
by this Agreement shall be attacked, endangered or questioned or if any legal
proceedings are instituted with respect thereto, the Company will take all
necessary and proper steps for the defense of such legal proceedings. The Agent
is authorized and empowered to take such additional steps as in its judgment and
discretion may be necessary or proper for the defense of any such legal
proceedings or the protection of the validity or priority of this Agreement and
the rights, titles, security interests and other interests created or evidenced
by this Agreement, and the Secured Obligations include all expenses so incurred
of every kind and character.

                  (f)      Regarding any proceedings relating to the Pledged
Collateral, or any portion thereof, the Agent may participate therein, and the
Company shall from time to time deliver to the Agent all instruments reasonably
requested by it to permit such participation. The Company shall, at its expense,
diligently prosecute any such proceedings and shall consult with the Agent, its
attorneys and experts, and cooperate with them in the carrying on or defense of
any such proceedings.

         6.       Voting Rights; Dividends; Etc.

                  (a)      So long as no Event of Default shall have occurred
and be continuing (and, in the case of clause (i) below, so long as written
notice has not been given by the Agent to the Company):

                           (i)      The Company shall be entitled to exercise
                  any and all voting and/or other consensual rights pertaining
                  to the Pledged Collateral or any part thereof for any purpose
                  consistent with the terms of this Agreement or the Credit
                  Agreement; provided, however, that the Company shall not
                  exercise or refrain from exercising any such right with the
                  primary intent of causing a Material Adverse Effect.

                           (ii)     The Company shall be entitled to receive and
                  retain any and all dividends paid in respect of the Pledged
                  Collateral (other than any and all

                                    (A)      dividends paid or payable other
                           than in cash in respect of, and instruments and other
                           property received, receivable or otherwise
                           distributed in respect of, or in exchange for, any
                           Pledged Collateral,

                                    (B)      dividends and other distributions
                           paid or payable in cash in respect of any Pledged
                           Collateral in connection with a partial or total
                           liquidation or dissolution or in connection with a
                           return of capital, capital surplus or
                           paid-in-surplus, and

                                       7
<PAGE>
                                    (C)      cash paid, payable or otherwise
                           distributed in redemption of, or in exchange for, any
                           Pledged Collateral,

         all of which shall be, and all of which shall be forthwith delivered to
         the Agent to hold as, Pledged Collateral and shall, if received by the
         Company, be received in trust for the benefit of the Agent, be
         segregated from the other property or funds of the Company, and be
         forthwith delivered to the Agent as Pledged Collateral in the same form
         as so received (with any necessary endorsement)).

                           (iii)    The Agent shall execute and deliver (or
                  cause to be executed and delivered) to the Company all such
                  proxies and other instruments as the Company may reasonably
                  request for the purpose of enabling the Company to exercise
                  the voting and other rights which it is entitled to exercise
                  pursuant to clause (i) above and to receive the dividends
                  which it is authorized to receive and retain pursuant to
                  clause (ii) above.

         Regardless of the Company's right described above to receive and retain
         certain rights and property, such rights and property nonetheless
         secure the repayment of the Secured Obligations and are a part of the
         Pledged Collateral.

                  (b)      Upon the occurrence and during the continuation of an
Event of Default:

                           (i)      All rights of the Company to exercise the
                  voting and other consensual rights which it would otherwise be
                  entitled to exercise pursuant to Section 6(a)(i) and the
                  obligations of the Agent under Section 6(a)(iii) shall cease
                  upon receipt by the Company of written notice of an Event of
                  Default, and all such rights shall thereupon become vested in
                  the Agent who shall thereupon have the sole right to exercise
                  such voting and other consensual rights;

                           (ii)     All rights of the Company to receive the
                  dividends which it would otherwise be authorized to receive
                  and retain pursuant to Section 6(a)(ii) shall cease upon
                  receipt by the Company of written notice of an Event of
                  Default, and all such rights shall thereupon become vested in
                  the Agent who shall thereupon have the sole right to receive
                  and hold as Pledged Collateral such dividends; and

                           (iii)    All dividends which are received by the
                  Company contrary to the provisions of clause (ii) of this
                  Section 6(b) shall be received in trust for the benefit of the
                  Agent, shall be segregated from other funds of the Company and
                  shall be forthwith paid over to the Agent as Pledged
                  Collateral in the same form as so received (with any necessary
                  endorsement).

                  (c)      In order to permit the Agent to exercise the voting
and other rights which it may be entitled to exercise pursuant to Section
6(b)(i), and to receive all dividends and distributions which it may be entitled
to receive under Section 6(b)(ii), the Company shall, if necessary, upon written
notice from the Agent, from time to time execute and deliver to the Agent
appropriate dividend payment orders and other instruments as the Agent may
reasonably request. To this end, the Company hereby irrevocably constitutes and
appoints the Agent the proxy and attorney-in-fact of the Company, with full
power of substitution, to vote, and to act

                                       8
<PAGE>
with respect to, any and all Pledged Collateral that is securities standing in
the name of the Company or with respect to which the Company is entitled to vote
and act, subject to the understanding that such proxy may not be exercised
unless an Event of Default has occurred and is continuing. The proxy herein
granted is coupled with an interest, is irrevocable, and shall continue until
payment in full in cash of the Secured Obligations, the termination of the
Commitments and the expiration or termination of all outstanding Letters of
Credit.

         7.       Agent Appointed Attorney-in-Fact. The Company hereby appoints
the Agent the Company's true and lawful attorney-in-fact, with full authority in
the place and stead of the Company and in the name of the Company or otherwise,
from time to time in the Agent's discretion, subject to Section 6, to take any
action and to execute any document or instrument which the Agent may reasonably
deem necessary or desirable to accomplish the purposes of this Agreement,
including, without limitation, to receive, endorse and collect all instruments
made payable to the Company representing any dividend, interest payment or other
distribution in respect of the Pledged Collateral or any part thereof and to
give full discharge for the same. The Agent's liability, if any, otherwise
arising under applicable law shall be limited to amounts actually received as a
result of the exercise of the powers granted to it herein. No Agent or Bank, and
no officer, director, employee or agent of the Agent or any Bank, shall be
responsible to the Company for any act or failure to act hereunder, except that
any such Person shall be responsible for its own gross negligence or willful
misconduct.

         8.       Agent May Perform. The Agent is authorized to perform, or
cause performance of, any agreement contained herein in the event that the
Company fails to timely perform the same, and the reasonable expenses of the
Agent incurred in connection therewith shall be payable by the Company. The
Agent is further authorized in its discretion to take any other action, either
on its own behalf or on behalf of the Company (and as regards actions taken on
behalf of the Company, this authorization is irrevocable and is an agency
coupled with an interest), as the Agent may elect, which the Agent may deem
necessary or appropriate to protect and preserve the rights, titles and
interests of the Agent hereunder. The powers conferred on the Agent pursuant to
this Agreement are conferred solely to protect the Secured Parties' interest in
the Pledged Collateral and shall not impose any duty or obligation on any
Secured Party to perform any of the powers herein conferred. No exercise of any
of the rights provided for in this Agreement constitute a retention of
collateral in satisfaction of indebtedness.

         9.       No Responsibility for Certain Actions; Indemnity. Neither the
Agent nor any other Secured Party shall have responsibility for (a) ascertaining
or taking action with respect to calls, conversions, exchanges, maturities,
tenders or other matters relative to any Pledged Collateral, whether or not the
Agent or any other Secured Party has or is deemed to have knowledge of such
matters, (b) taking any necessary steps to preserve any rights against any
Person with respect to any Pledged Collateral, or (c) supervising, monitoring or
controlling any aspect of the character or condition of any of the Pledged
Collateral or any operations conducted in connection with it for the benefit of
the Company or any other Person. The Company agrees to indemnify, defend and
hold Secured Parties, their respective shareholders, directors, officers,
agents, advisors and employees (collectively "Indemnified Parties") harmless
from and against any and all loss, liability, obligation, damage, penalty,
judgment, claim, deficiency, expense, action, suit, cost and disbursement of any
kind or nature whatsoever (including interest, penalties, attorneys' fees and
amounts paid in settlement), imposed on, incurred by or asserted

                                       9
<PAGE>
against the Indemnified Parties growing out of or resulting from this Agreement
or any transaction or event contemplated in it (except that such indemnity shall
not be paid to any Indemnified Party to the extent such loss, etc. directly
results from the gross negligence or willful misconduct of any of the
Indemnified Parties).

         10.      Remedies upon Default. If any Event of Default shall have
occurred and be continuing:

                  (a)      The Agent may exercise in respect of the Pledged
Collateral, in addition to other rights and remedies provided for herein or
otherwise available to it, all the rights and remedies of a secured party after
default under the Uniform Commercial Code (the "Code") in effect in the State of
New York at that time (or such similar Canadian law legislation as may be
applicable, including the Personal Property Security Act (Alberta) and the Civil
Enforcement Act (Alberta), at that time), and, subject to applicable regulatory
and legal requirements, the Agent may also, without notice except as specified
below, sell the Pledged Collateral or any part thereof in one or more parcels at
public or private sale, at any exchange, broker's board or at any of the Agent's
offices or elsewhere, for cash, on credit or for future delivery, and upon such
other terms as the Agent may deem commercially reasonable. Upon consummation of
any such sale, the Agent shall have the right to assign, transfer and deliver to
the purchaser or purchasers thereof the Pledged Collateral so sold. Each such
purchaser at any such sale shall hold the property sold absolutely free from any
claim or right on the part of the Company, and the Company, for itself and for
its successors, receivers, trustees and assigns, and for any and all persons
ever claiming any interest in the Pledged Collateral, to the extent permitted by
law, hereby WAIVES all rights of extension, redemption, stay, valuation and
appraisal, and any similar right arising under the law of any country, which the
Company now has or may at any time in the future have under any rule of law or
statute now existing or hereafter enacted. The Company agrees that, to the
extent notice of sale shall be required by law, at least 10 days' notice to the
Company of the time and place of any public sale or the time after which any
private sale is to be made shall constitute reasonable notification. The Agent
shall not be obligated to make any sale of Pledged Collateral regardless of
notice of sale having been given. The Agent may adjourn any public or private
sale from time to time by announcement at the time and place fixed therefor, and
such sale may, without further notice, be made at the time and place to which it
was so adjourned. The Company hereby WAIVES any claims against the Agent arising
by reason of the fact that the price at which any Pledged Collateral may have
been sold at such a private sale was less than the price which might have been
obtained at a public sale, even if the Agent accepts the first offer received
and does not offer such Pledged Collateral to more than one offeree. At any
public sale made pursuant to this Section 10, any Secured Party may bid for or
purchase, free from any right of redemption, stay or appraisal, and any similar
right arising under the law of any country, on the part of the Company (all said
rights being also hereby WAIVED and released), the Pledged Collateral or any
part thereof offered for sale and may make payment on account thereof by using
any claim then due and payable to it from any Borrower, any Guarantor and/or the
Company as a credit against the purchase price, and it may, upon compliance with
the terms of sale, hold, retain and dispose of such property without further
accountability to the Company therefor. For purposes hereof, (i) a written
agreement to purchase the Pledged Collateral or any portion thereof shall be
treated as a sale thereof, (ii) the Agent shall be free to carry out such sale
pursuant to such agreement and (iii) the Company shall not be entitled to the
return of the Pledged Collateral or any portion thereof subject thereto,

                                       10
<PAGE>
notwithstanding the fact that after the Agent shall have entered into such an
agreement all Events of Default shall have been remedied and the Secured
Obligations paid in full. As an alternative to exercising the power of sale
herein conferred upon it, the Agent may proceed by a suit or suits at law or in
equity to foreclose upon the Pledged Collateral and to sell the Pledged
Collateral or any portion thereof pursuant to a judgment or decree of a court or
courts having competent jurisdiction or pursuant to a proceeding by a
court-appointed receiver. Any sale pursuant to the provisions of this Section 10
shall be deemed to conform to the commercially reasonable standards as provided
in the Code. The Company covenants and agrees that it will execute and deliver
such documents and take such other action as the Agent deems necessary or
advisable in order that any such sale may be made in compliance with applicable
law.

                  (b)      In addition to the rights and remedies described in
paragraph (a) of this Section 10, the Agent shall have all the following rights
and remedies:

                           (i)      it shall not be necessary that the Pledged
                  Collateral or any part thereof be present at the location of
                  any sale pursuant to the provisions of this Section 10;

                           (ii)     the sale by the Agent of less than the whole
                  of the Pledged Collateral shall not exhaust the rights of the
                  Agent hereunder, and the Agent is specifically empowered to
                  make successive sale or sales hereunder until the whole of the
                  Pledged Collateral shall be sold; and, if the proceeds of such
                  sale of less than the whole of the Pledged Collateral shall be
                  less than the aggregate of the Secured Obligations, this
                  Agreement and the security interest created hereby shall
                  remain in full force and effect as to the unsold portion of
                  the Pledged Collateral just as though no sale had been made;

                           (iii)    in the event any sale hereunder is not
                  completed or is defective in the opinion of the Agent, such
                  sale shall not exhaust the rights of the Agent hereunder and
                  the Agent shall have the right to cause a subsequent sale or
                  sales to be made hereunder; and

                           (iv)     demand of performance, advertisement and
                  presence of property at sale are hereby WAIVED and the Agent
                  is hereby authorized to sell hereunder any financial asset it
                  may hold as security for the Secured Obligations. All demands
                  and presentments of any kind or nature are expressly WAIVED by
                  the Company. The Company hereby WAIVES the right to require
                  the Agent to pursue any other remedy for the benefit of the
                  Company and agrees that Secured Party may proceed against any
                  Person for the amount of the Obligations owed to the Agent
                  without taking any action against any other Person and without
                  selling or otherwise proceeding against or applying any of the
                  Pledged Collateral in the Agent's possession.

                  (c)      The Company recognizes that, by reason of certain
prohibitions contained in the Securities Act of 1933 and applicable state
securities laws, the Agent may be compelled, with respect to any sale of all or
any part of the Pledged Collateral, to limit purchasers to those who will agree,
among other things, to acquire such securities for their own account, for

                                       11
<PAGE>
investment, and not with a view to the distribution or resale thereof. The
Company acknowledges and agrees that any such sale may result in prices and
other terms less favorable to the seller than if such sale were a public sale
without such restrictions and agrees that such circumstances shall not be a
factor in determining whether such sale has been made in a commercially
reasonable manner. The Agent shall be under no obligation to delay the sale of
any of the Pledged Collateral for the period of time necessary to permit the
Company to register such securities for public sale under the Securities Act of
1933, or under applicable state securities laws, even if the Company would agree
to do so.

                  (d)      If the Agent determines to exercise its right to sell
any or all of the Pledged Collateral, upon written request, the Company shall,
and shall cause each of its direct Subsidiaries to, from time to time, furnish
to the Agent all such information as the Agent may reasonably request in order
to determine the number of shares and other instruments included in the Pledged
Collateral which may be sold by the Agent as exempt transactions under the
Securities Act of 1933 and rules of the Securities and Exchange Commission
thereunder, as the same are from time to time in effect.

                  (e)      Any cash held by the Agent as Pledged Collateral and
all cash proceeds received by the Agent in respect of any sale of, collection
from, or other realization upon all or any part of the Pledged Collateral shall
be applied by the Agent (unless otherwise required by law):

                  First, to the payment of the costs and expenses of retaking,
         holding, preparing for sale, or selling the Pledged Collateral or any
         portion thereof, including all expenses (including, without limitation,
         any legal fees and disbursements and the allocated cost of in-house
         counsel), liabilities and advances made or incurred by the Agent in
         connection therewith;

                  Next, to the Agent and the other Secured Parties in partial
         payment of the Secured Obligations; and

                  Finally, after payment in full in cash of all Secured
         Obligations, termination of the Commitments and expiration or
         termination of all outstanding Letters of Credit, to the payment to the
         Company, or its successors or assigns, or to whomsoever may be lawfully
         entitled to receive the same or as a court of competent jurisdiction
         may direct, of any surplus then remaining from such cash and cash
         proceeds.

                  (f)      All remedies herein expressly provided for are
cumulative of any and all other remedies existing at law or in equity and are
cumulative of any and all other remedies provided for in any other instrument
securing the payment of the Obligations, or any part thereof, or otherwise
benefiting the Secured Parties, and the resort to any remedy provided for
hereunder or under any such other instrument or provided for by law shall not
prevent the concurrent or subsequent employment of any other appropriate remedy
or remedies.

                  (g)      The Secured Parties may resort to any security given
by this Agreement or to any other security now existing or hereafter given to
secure the payment of the Obligations, in

                                       12
<PAGE>
whole or in part, and in such portions and in such order as may seem best to
such Secured Party in its sole and uncontrolled discretion, and any such action
shall not in anywise be considered as a waiver of any of the rights, benefits or
security interests evidenced by this Agreement.

         11.      Expenses. The Company will upon demand pay to the Agent the
amount of any and all reasonable costs, disbursements and expenses of every
character, including without limitation the reasonable fees and expenses of its
counsel (including the reasonable allocated cost of in-house counsel), subject
to the limitations expressed in Section 13.5 of the Credit Agreement, and of any
experts, incurred or expended by the Agent from time to time in connection with:
(a) the preparation, negotiation, documentation, closing, renewal, revision,
modification, renegotiation or review of this Agreement; (b) the custody or
preservation of, or the sale of, collection from, or other realization upon, any
of the Pledged Collateral, (c) the exercise or enforcement of any of the rights
of the Agent or any other Secured Party hereunder, or (d) the failure by the
Company to perform or observe any of the provisions hereof.

         12.      Amendments, Etc. No amendment or waiver of any provision of
this Agreement nor consent to any departure by the Company herefrom shall in any
event be effective unless the same shall be in writing and signed by the Agent,
and, in the case of amendment, by the Company, and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given and to the extent therein specified. The Agent may waive any
default without waiving any other prior or subsequent default, and the Agent may
remedy any default without waiving the default remedied. The failure by the
Agent to exercise any right, power or remedy upon any default shall not be
construed as a waiver of such default or as a waiver of the right to exercise
any such right, power or remedy at a later date. No single or partial exercise
by the Agent of any right, power or remedy hereunder shall exhaust the same or
shall preclude any other or further exercise thereof, and every such right,
power or remedy hereunder may be exercised at any time and from time to time. No
notice to nor demand on the Company in any case shall of itself entitle the
Company to any other or further notice or demand in similar or other
circumstances. Acceptance by the Agent of any payment in an amount less than the
amount then due on the Secured Obligations shall be deemed an acceptance on
account only and shall not in any way affect the existence of a default
hereunder. No waiver, release, consent by Agent pursuant to this Agreement shall
affect or impair the rights of a Secured Party against any third party, except
to the extent specifically agreed to by the Secured Party in such writing.

         13.      Address for Notices. Except as otherwise provided herein, all
notices, requests and other communications provided for pursuant to this
Agreement or any other Credit Document shall be in writing (including
telegraphic, telex, facsimile transmission or cable communication and confirmed
in original writing) and mailed, telegraphed, telexed, telefaxed, cabled or
delivered, if to the Company to its address specified on the signature page of
this Agreement; if to any Bank, to its Domestic Lending Office; and if to the
Agent, to its address specified on the signature pages of the Credit Agreement;
or, if to the Company or the Agent, to such other address as shall be designated
by such party in a written notice to the other party. All such notices and
communications shall be effective (i) if mailed, on the fifth day after being
deposited in the United States Postal Service, (ii) on the next day after being
delivered to a service for overnight delivery, (iii) if telegraphed, telecopied,
cabled or telexed, on the day delivered to the telegraph company, transmitted by
telecopier, confirmed by telex answerback or

                                       13
<PAGE>
delivered to the cable company, respectively, or (iv) if delivered, upon
delivery, except that notices pursuant to Article XI of the Credit Agreement
shall not be effective until received by the Agent. Actual notice shall always
be effective.

         14.      Continuing Security Interest. This Agreement shall create a
continuing security interest in the Pledged Collateral and shall (a) remain in
full force and effect until payment in full in cash (after the termination of
the Commitments and the expiration or termination of all outstanding Letters of
Credit) of the Secured Obligations; (b) continue to be effective if at any time
payment and performance of the Secured Obligations is, pursuant to applicable
law, rescinded or reduced in amount, or must otherwise be restored by the Agent
or any other Secured Party; (c) be binding upon the Company, its successors and
assigns, and any trustee, receiver, or conservator of the Company, and any
successors in interest of the Company in and to all or any part of the Pledged
Collateral; and (d) inure, together with the rights and remedies of the Agent
hereunder, to the benefit of the Agent, the other Secured Parties and their
respective successors, transferees and assigns. Without limiting the generality
of the foregoing clause (d), the Agent and/or any Bank may assign or otherwise
transfer its rights and obligations under the Credit Agreement to any other
Person or entity, and such other Person or entity shall thereupon become vested
with all the benefits in respect thereof granted to such Bank herein or
otherwise, all as provided in, and to the extent set forth in, the Credit
Agreement. Upon the payment in full in cash (after the termination of the
Commitments and the expiration or termination of all outstanding Letters of
Credit) of the Secured Obligations, the Company shall be entitled to the return,
upon its request and at its expense, of such of the Pledged Collateral as shall
not have been sold or otherwise applied pursuant to the terms hereof.

         15.      Security Interest Absolute. All rights and security interests
of the Secured Parties hereunder, and all obligations of the Company hereunder,
shall be absolute and unconditional irrespective of:

                  (a)      any lack of validity or enforceability of the Credit
Agreement, any other Credit Document, or any other agreement or instrument
relating thereto;

                  (b)      any change in the time, manner or place of payment
of, or in any other term of, all or any of the Secured Obligations (including,
without limitation, the possible extension of the Commitment Termination Date
and increase of the amount of the Commitments all on the terms and conditions
set forth in the Credit Agreement), or any other amendment, renewal or waiver of
or any consent to any departure from the Credit Agreement or any other Credit
Document;

                  (c)      any exchange, release or non-perfection of any other
collateral, or any release or amendment or waiver of or consent to departure
from any guaranty, for all or any of the Obligations;

                  (d)      any indulgence, moratorium or release granted by any
Secured Party, including but not limited to (i) any renewal, extension or
modification which a Secured Party may grant with respect to the Obligations,
(ii) any surrender, compromise, release, renewal, extension, exchange or
substitution which a Secured Party may grant in respect of any item

                                       14
<PAGE>
securing the Obligations, or any part thereof or any interest therein, or (iii)
any release or indulgence granted to any endorser, guarantor or surety of the
Obligations; or

                  (e)      any other circumstance which might otherwise
constitute a defense available to, or a discharge of, the Company or a third
party pledgor.

         16.      Use of Copies. Any carbon, photographic or other reproduction
of this Agreement or any financing statement signed by the Company is sufficient
as a financing statement for all purposes, including without limitation, filing
in any state as may be permitted by the provisions of the Uniform Commercial
Code of such state.

         17.      Right of Set-off.

                  (a)      Upon the occurrence and during the continuation of
any Event of Default under the Credit Agreement, each Bank is hereby authorized
at any time and from time to time, to the fullest extent permitted by law, to
set-off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing
by such Bank to or for the credit or the account of the Company against any and
all of the Secured Obligations, irrespective of whether or not such Bank shall
have made any demand under this Agreement and although such Secured Obligations
may be contingent and unmatured. Each Bank which sets-off pursuant to this
Section 17(a) shall give prompt notice to the Company following the occurrence
thereof; provided that the failure to give such notice shall not affect the
validity of the set-off.

                  (b)      Any payment obtained by any Bank pursuant to Section
17(a) (or in any other manner directly from the Company) shall be remitted to
the Agent and distributed among the Secured Parties in accordance with the
provisions of Section 10(e).

         18.      Severability. If for any reason any provision or provisions
hereof are determined to be invalid and contrary to any existing or future law,
such invalidity shall not impair the operation of or affect those portions of
this Agreement which are valid. Each waiver in this Agreement is subject to the
overriding and controlling rule that it shall be effective only if and to the
extent that (a) it is not prohibited by applicable law and (b) applicable law
neither provides for nor allows any material sanctions to be imposed against the
Secured Parties for having bargained for and obtained it.

         19.      WAIVER OF JURY TRIAL. THE COMPANY HEREBY WAIVES AND AGREES TO
WAIVE ANY RIGHT IT MAY HAVE TO A JURY TRIAL IN CONNECTION WITH ANY ACTION, SUIT
OR PROCEEDING ARISING OUT OF OR RELATED IN ANY WAY TO THIS AGREEMENT OR ANY
OTHER CREDIT DOCUMENT.

         20.      GOVERNING LAW; JURISDICTION.

                  (a)      THIS AGREEMENT AND EACH ISSUE ARISING HEREUNDER SHALL
BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK (EXCLUDING ITS CONFLICTS OF LAWS PRINCIPLES), EXCEPT TO THE EXTENT PROVIDED
IN SECTION 13.14(b) OF THE CREDIT AGREEMENT AND TO THE EXTENT THAT THE FEDERAL
LAWS OF

                                       15
<PAGE>
THE UNITED STATES OF AMERICA MAY OTHERWISE APPLY. THE PARTIES AGREE THAT THIS
CHOICE OF NEW YORK LAW HAS BEEN MADE PURSUANT TO SECTION 5-1401 OF THE GENERAL
OBLIGATIONS LAW OF THE STATE OF NEW YORK. UNLESS OTHERWISE DEFINED HEREIN OR IN
THE CREDIT AGREEMENT, TERMS DEFINED IN ARTICLES 8 AND 9 OF THE UNIFORM
COMMERCIAL CODE IN THE STATE OF NEW YORK ARE USED HEREIN AS THEREIN DEFINED.

                  (b)      EXCEPT AS OTHERWISE PROVIDED IN SECTION 20(d), ANY
LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT MAY BE BROUGHT IN THE
COURTS OF THE STATE OF NEW YORK LOCATED IN THE BOROUGH OF MANHATTAN OR OF THE
UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND BY EXECUTION
AND DELIVERY OF THIS AGREEMENT, THE COMPANY HEREBY CONSENTS, FOR ITSELF AND IN
RESPECT OF ITS PROPERTY, TO THE JURISDICTION OF THE AFORESAID COURTS. THE
COMPANY HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING WITHOUT LIMITATION,
ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON
CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR
PROCEEDING IN SUCH JURISDICTION IN RESPECT OF THIS AGREEMENT, ANY OTHER CREDIT
DOCUMENT, OR ANY DOCUMENT RELATED TO THIS AGREEMENT OR ANY OTHER CREDIT
DOCUMENT. THE COMPANY AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR
PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN ANY OTHER JURISDICTIONS BY
SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW. The parties agree
that, for the purpose of any proceeding brought in The Netherlands to enforce a
final judgment of the aforesaid courts, (a) the pledge and grant of a security
interest described in Section 1 of this Agreement shall be construed to grant to
the Agent, in addition, a first ranking right of pledge (pandrecht) under the
law of The Netherlands and (b) any findings of fact rendered by such courts
shall be (and shall be deemed to be) admitted by each party.

                  (c)      The Company has irrevocably appointed CT Corporation

which may be served in any action or proceeding arising out of or relating to
this Agreement. Such service may be made by mailing or delivering a copy of such
process to the Company in care of the Process Agent at the Process Agent's above
address, and the Company hereby irrevocably authorizes and directs the Process
Agent to accept such service on its behalf. As an alternative method of service,
the Company also irrevocably consents to the service of any and all process in
any such action or proceeding by the mailing of copies of such process to the
Company at its address specified on the signature page hereof. Process may be
served in English, and the Company irrevocably waives any right accruing to it
under the Hague Convention on the Service Abroad of Judicial and Extrajudicial
Documents, the Hague Convention on the Taking of Evidence Abroad in Civil or
Commercial Matters, the law of The Netherlands, and any similar treaty regarding
the service of process or the collection of evidence. Any process and documents
to be sent to the other party containing languages other than English shall be
sent with English translations certified by the sender, and the sending party
shall bear the translation costs.

                  (d)      Nothing in this Section 20 shall affect the right of
the Agent or any other Secured Party to serve legal process in any other manner
permitted by law or affect the right of

                                       16
<PAGE>
the Agent or any other Secured Party to bring any action or proceeding against
the Company in the courts of any other jurisdictions.

                  (e)      To the extent the Company has or hereafter may
acquire any immunity from jurisdiction of any court or from any legal process
(whether through service or notice, attachment prior to judgment, attachment in
aid of execution, execution or otherwise) with respect to itself or its
property, the Company hereby irrevocably waives such immunity in respect of its
obligations under this Agreement.

                  (f)      THIS AGREEMENT TOGETHER WITH THE OTHER CREDIT
DOCUMENTS EMBODIES THE ENTIRE AGREEMENT AND UNDERSTANDING AMONG THE PARTIES WITH
RESPECT TO ITS SUBJECT MATTER AND SUPERSEDES ALL PRIOR OR CONTEMPORANEOUS
AGREEMENTS AND UNDERSTANDINGS OF SUCH PERSONS, VERBAL OR WRITTEN, RELATING TO
SUCH SUBJECT MATTER.

         21.      Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original for all purposes;
but such counterparts shall be deemed to constitute but one and the same
instrument.

         22.      Waiver of Subrogation. The Company expressly WAIVES any and
all rights of subrogation, reimbursement and contribution (contractual,
statutory or otherwise) against the Secured Parties, individually and
collectively, including without limitation, any claim or right of subrogation
under the Bankruptcy Code (Title 11 of the U.S. Code) or any successor statute,
arising from the existence or performance of this Agreement and the Company
irrevocably WAIVES any right to enforce any remedy which the Secured Parties, or
any one or more of them, now have or may hereafter have against Borrowers and
WAIVES any benefit of, and any right to participate in, any security now or
hereafter held by the Secured Parties, or any one or more of them, until the
Secured Obligations have been paid and performed in full (after the termination
of the Commitments and the expiration or termination of all outstanding Letters
of Credit).

         23.      Subordination. The Company hereby expressly covenants and
agrees for the benefit of the Secured Parties that all obligations and
liabilities of the Borrowers to the Company of whatsoever description
(including, without limitation, all intercompany receivables of the Company from
each of the Borrowers) shall be subordinated and junior in right of payment to
the Secured Obligations. Following the occurrence of an Event of Default, all
indebtedness of the Borrowers to the Company shall, if the Agent shall so
request, be collected and received by the Company as trustee for the Secured
Parties and paid over to the Secured Parties, or any one or more of them, as the
case may be, on account of the Secured Obligations, but without reducing or
affecting in any manner the obligations of the Company under this Agreement.

         24.      Incorporation by Reference.

                  (a)      Article I of the Credit Agreement is incorporated by
reference in this Agreement. Article XII of the Credit Agreement is incorporated
by reference in this Agreement with the same effect as if the Company were named
as a Borrower therein.

                                       17
<PAGE>
                  (b)      The limitation on the Secured Obligations described
in Section 2 of this Agreement shall not affect or excuse the liability or
obligations of any Guarantor, nor may any similar limitation in Section 11.2 of
the Credit Agreement be raised as a defense to any action or claim against the
Company (collectively, such limitations are herein referred to as the
"Limitations"). The Agent shall have the right to determine and designate from
time to time, without notice or assent of the Company, which portions of the
Obligations to which such limitations apply, and the Company acknowledges that
such determination and designation shall be conclusive. This Agreement shall not
fail or be ineffective or invalid or be considered too indefinite or contingent
with respect to the Company because the deemed Guaranteed Debt applicable to the
Company may fluctuate from time to time or for any other reason. The Company
agrees that, as it relates to its deemed Guaranteed Debt, any payment or
prepayment by any Guarantor or any other Person against any part of the Secured
Obligations shall be deemed paid first against that portion that is limited by
the Limitations, and the balance, if any, shall be applied to remaining Secured
Obligations, in such order and manner as the Agent shall determine in its sole
discretion. The Company's covenants, agreements and obligations under this
Agreement shall in no way be released, diminished, reduced, impaired or
otherwise affected by reason of the happening from time to time of any of the
matters, events or conditions described in Section 11.4 of the Credit Agreement,
regardless of whether the Company is given any notice or is asked for or gives
any consent (all requirements for which, however arising, the Company hereby
WAIVES). In addition to the other terms and conditions of this Agreement, the
Company agrees that every waiver, release, subordination, representation,
warranty and agreement described in Article XI of the Credit Agreement (except
those imposing vicarious, personal liability on Guarantors for the Obligations
(e.g., Sections 11.2, 11.7 and 11.19)) are hereby made by the Company and made a
part of this Agreement, and the same shall apply, with necessary changes in
points of detail, to this Agreement to the same extent as if the Company were
named as a Guarantor and Borrower in the Credit Agreement.

         25.      Miscellaneous Terms.

                  (a)      The Company represents and warrants to the Agent and

US$100,000 in each case, without (i) notifying the Agent in writing at least
five days in advance of the incurrence of the debt (unless the creditor is a
Subsidiary of WGI) or the issuance of the guarantee and, (ii) unless such
obligee is a Subsidiary of WGI having actual knowledge of the pledge and
security interest granted in this Agreement, informing the obligee in writing of
the existence, nature and extent of the pledge and security interest granted in
this Agreement.

                  (c)      The Company shall cause to be prominently noted each

terms and conditions:

         WHEREAS, the Mortgagor is the sole legal owner of the whole (100%) of
the Vessel (as herein defined).

         WHEREAS, pursuant to the terms of a Credit Agreement dated as of June
14, 2002 (the "Credit Agreement"), the Banks agreed to make available to

Event of Default (as defined in the Credit Agreement) has occurred and is

(which determination shall be conclusive absent manifest error) that it is
unable to ascertain the Federal Funds Rate for any reason, including the
inability or failure of the Agent to obtain sufficient bids or publications in
accordance with the terms of the Credit Agreement, the Base Rate shall be the
Prime Rate until the circumstances giving rise to such inability no longer
exist.

         "Base Rate Loan" means a Loan that bears interest as provided in the
Credit Agreement at a rate per annum based on the Base Rate.

         "Business Day" means any day other than a Saturday, Sunday or other day

                            ------------------------------------

         Where "Eurodollar Reserve Percentage" means for any Interest Period for
Eurodollar Rate Loans the maximum reserve percentage (expressed as a decimal,
rounded upward, if necessary, to the nearest 1/100th of one percent) as
determined by the Agent in effect on the date LIBOR for such Interest Period is
determined (whether or not applicable to any Bank) under regulations issued from
time to time by the U.S. Federal Reserve Board for determining the maximum
reserve requirement (including basic, emergency, supplemental and other marginal
reserve requirements) with respect to liabilities or assets consisting of or
including Eurocurrency Liabilities having a term equal to such Interest Period;
and "LIBOR" means for any Interest Period for Eurodollar Rate Loans, the per

available, "LIBOR" applicable to any Interest Period for Eurodollar Rate Loans
shall be the per annum rate (rounded upward, if necessary, to the nearest
1/100th of one percent) determined by the Agent based upon rates quoted at
approximately 10:00 a.m. (London time) (or as soon thereafter as practicable) on
the day two Business Days prior to the first day of such Interest Period for the

of Dollar deposits for delivery on the first day of such Interest Period, in
immediately available funds and having a term comparable to such Interest Period
and in an amount comparable to the principal amount of the respective Eurodollar
Rate Loan to which such Interest Period relates. Each determination by the Agent
of the Eurodollar Reserve Percentage and LIBOR shall be conclusive and binding,
absent manifest error.

premium due for other insurances, nor cancel any of the Insurances for reason of
non-payment of premiums for other vessels under such fleet coverage or premiums
for other insurances, and shall undertake to issue a separate policy or policies
in respect of

                                       12

so requested by the Mortgagee.

                  (i)      Upon occurrence of an Event of Default, as provided
for in Clause 20 hereof, the Mortgagee shall be entitled to settle any dispute
with the insurers, associations or clubs which may arise from their liability
under the respective insurance contracts or other instruments of coverage or on
the amount of compensation which they may be required to pay, with binding
effects on the rights of the Mortgagor under such insurance or cover. The
Mortgagor shall obtain the necessary consents from its insurers and war risks
and protection and indemnity clubs or associations in which the Vessel may be
entered, and inclusion, in the respective insurance policies and other
instruments of coverage or by way of an undertaking of the protection and
indemnity associations or clubs, acceptable to the Mortgagee, of any references
which the Mortgagee may deem necessary to obtain and preserve this option for
its benefit.

waters not fully covered under any or all of the Insurances herein contemplated,
to trade or carry on business which is forbidden by international law or which

                  performance of this Mortgage.

                           (iii)    That the execution, delivery and performance
                  of this Mortgage will not constitute a breach or violation of

                  of this Mortgage will not constitute default or possible
                  default, that is to say, an event which with the lapse of time
                  or notice or both would constitute an event of default, under

                  to which it is or may be a party or by which any of its
                  properties or assets are or may be bound, nor will it
                  otherwise make or give cause for any obligation to which it is
                  a party to become immediately due and payable or otherwise
                  enforceable.

                                       15

                  resolution or other regulation or decision of any judicial,
                  administrative or municipal authority applicable thereto.

                           (vi)     That it is not a defendant party in any

                  litigation or proceeding to be initiated against it.

Mortgagee may deem advisable, and to collect all Earnings and Insurances and

Mortgagor, and to repair, renew, alter, insure, cover, survey and reclass the
Vessel or any part of her, and generally to do or cause to be done all such acts
matters or things and enter into all such engagements and arrangements for the

                  remuneration of any Persons or corporations involved in
                  relation to the management or operation of the Vessel; and

                           (iii)    all the reasonable costs and running

Vessel, and to institute such legal proceedings as the Mortgagee shall think
proper in connection with such monies and to defend, discharge, compound,
release and compromise any legal proceedings brought against the Mortgagor as
owner of the Vessel, or against the Vessel or its master.

22.      THE MASTER

         The Mortgagor hereby agrees that if the Mortgagee shall exercise any of
its powers under the foregoing Clause 21 the master of the Vessel for the time
being shall be entitled to and shall act on the orders of the Mortgagee on proof
only that the Person giving such order is the Mortgagee or a duly appointed
representative of the Mortgagee and without the need to prove to the master's
satisfaction that the Mortgagee is entitled to such exercise of the right of
giving orders.

23.      SALE PROVISIONS

                  (a)      Any sale of the Vessel effected under this Mortgage,

purchaser shall not be bound to enquire or to establish whether or not the power
of sale has arisen or become exercisable, nor as to the propriety and regularity
of such sale, nor shall any such purchaser or purchasers be affected by notice
that such sale was or is unnecessary or improper and, notwithstanding any
impropriety or irregularity, any such sale shall, as regards the protection of
the Vessel and the purchaser's title thereto, be deemed valid and effectual; the
only remedy of the Mortgagor in respect of any alleged impropriety or
irregularity shall be for damages against or from the Mortgagee.

                  (c)      Upon any sale of the Vessel effected under this
Mortgage the receipt of the Mortgagee or of the court officer conducting any
such sale for the purchase money and any other moneys so paid shall be a full
and sufficient discharge to any purchaser and no such purchaser, or his
representatives, successors or assigns, after paying such moneys and receiving
such receipt, shall be concerned with the application of such moneys to any
purpose of this Mortgage or in any manner be answerable for any loss,
mis-application or non-application of any such moneys or any part thereof.

                  (d)      Upon completion of any non-judicial sale of the
Vessel effected under this Mortgage, the Mortgagee shall execute and deliver to
the purchaser a good and sufficient instrument in respect of the sale and
transfer of the Vessel and for that purpose the Mortgagor hereby

                                       18

security) the Mortgagee to be its lawful attorney in its name and stead to

Mortgagee pursuant to or under the terms of this Mortgage, the application of

incurred by the Mortgagee, and adequately to indemnify the Mortgagee against all
claims asserting priority over or equality with the right of the Mortgagee over
the Vessel;

         SECOND: To interest and fees accrued and unpaid in respect of the
Secured Obligations and then to principal sums due in respect of the Secured
Obligations;

         THIRD: To the payment of all other non-contingent Secured Obligations;

         FOURTH: By deposit into the Cash Collateral Account, an amount
sufficient to cash collateralize all contingent Secured Obligations as

         FIFTH: To the payment of any surplus thereafter remaining to the
Mortgagor or to whomsoever may be lawfully entitled thereto.

         PROVIDED ALWAYS that in the event that such moneys are insufficient to
pay the amounts specified in FIRST through FOURTH above the Mortgagee shall be
entitled to collect the balance from the Mortgagor personally or from any other
Person liable therefor.

25.      EVENT OF ARREST OR DETENTION

         In the event that the Vessel shall be arrested or detained by any
officer of any court or by any other authority of any kind or in the event that
the Mortgagee may become entitled to proceed as provided for in Clause 21
hereof, the Mortgagor hereby irrevocably appoints the Mortgagee and its officers

to do any and all acts and things which they may deem necessary or convenient,
as if they were the Mortgagor, including without limitation, to receive or take
possession and appoint

the Vessel.

26.      POWERS OF MORTGAGEE CUMULATIVE AND NO WAIVER

         Each and every power and remedy herein given to the Mortgagee shall be
cumulative and shall be in addition to every other power and remedy given herein
or now or hereafter existing at law, in admiralty, by statute or otherwise, and
each and every power and remedy whether given herein or otherwise existing may
be exercised from time to time and as often and in such order as may be deemed
expedient by the Mortgagee, and, except for the running of the pertinent statute
of limitations as may be established by applicable law, the delay or omission to
exercise or the failure to exercise or the partial exercise of any such power or
remedy shall not be construed as a waiver of the right to exercise
simultaneously any other power or remedy nor as a waiver of the right to
subsequently proceed to make use of the same or of any other power or remedy.

27.      CONTINUING SECURITY

Documents.

               payable quarterly in arrears and calculated at the Applicable
               Margin specified therefor in the Pricing Schedule.

               this Mortgage or any other Credit Document of an annual nature
               shall accrue from day to day and shall be calculated on the

               which shall calculated on the actual number of days elapsed in a

                 and (where appropriate) recording of the this Mortgage and any
                 other documents delivered pursuant to the Mortgage or in

         incur for repairs, insurance premiums, payments of claims, whether or
         not giving rise to liens or privileges on the Vessel, defense of suits,
         or for any other purpose whatsoever related hereto or to the Credit

         Mortgage or any other Credit Document pursuant to any judgment or order
         of any court or otherwise shall operate to discharge the liability of
         the Mortgagor for payment of the Secured Obligations unless and until
         payment in full of the Secured Obligations shall have been received by
         the Mortgagee for the benefit of the Banks. To the extent that the

         Dollars and on actual conversion from such currency shall fall short of
         the amount of the relevant obligation expressed in U.S. Dollars, the
         Mortgagee and the Banks shall have a further and separate cause of
         action against the Mortgagor for the recovery of the amount of the
         shortfall.

the event of an attachment, seizure or arrest of the Vessel or other detention
thereof in the exercise of any of the aforesaid liens, shall procure the release

any other Person has or shall have any right, power or authority to create or to
permit the creation of any obligations whatsoever involving the use or operation
of the Vessel which may give rise to liens or privileges thereon, other than the
obligations secured by this Mortgage, and obligations for crew's wages, salvage,
stevedores' and other wharfers' compensation or general average contributions,
without the written consent of the Mortgagee first obtained. Said written

        shipowner, any charterer, the Master of the Vessel nor any other person
        has any right, power or authority to create, incur or permit to be

10.     INSURANCES

         (a) The Mortgagor at its expense shall keep the Vessel and her rights
fully covered by the Insurances, in each case in the Required Amount and/or with
such insurers (or, in the case of War Risks and Protection and Indemnity Risks,
such English or Norwegian war risks and protection and indemnity clubs or
associations and policies) and by utilizing the

                                       10
<PAGE>

services of such first class insurance brokers as the Mortgagee may approve. The
Mortgagor agrees that it will punctually pay all insurance premiums, will timely
submit (when relevant) U.S. Voyage Declarations in accordance with the
Protection and Indemnity Risk terms of cover, will timely renew the Insurances
and ensure that annual certificates are delivered to the Mortgagee evidencing
that the Vessel is insured and that the Mortgagee is noted as mortgagee and loss
payee in all the Vessel's insurance policies.

         (b) With respect to Protection and Indemnity Risks coverage, all moneys
for claims under said coverage shall be paid to the Mortgagor; provided,
however, that upon the occurrence of an Event of Default (as defined herein),
all moneys for claims under said coverage shall be paid directly to the
Mortgagee or as the Mortgagee may direct. The Mortgagor shall obtain the
necessary consents or endorsements in the instruments of coverage or
undertakings from the relevant protection and indemnity association or club
where the Vessel may be entered which the Mortgagee may deem necessary or
acceptable in order to substantially obtain and preserve the benefits of this
Clause.

         (c) The Mortgagor shall procure that all instruments of coverage
referred to in this Clause as relate to Insurances are effected through the
approved brokers and are deposited with the approved brokers and that the
approved brokers furnish the Mortgagee with pro forma copies thereof and a
letter or letters of undertaking in such form as may be from time to time
required by the Mortgagee.

         (d) The Mortgagor shall procure that any protection and indemnity
and/or war risks clubs or associations wherein the Vessel is entered shall
furnish the Mortgagee with a letter or letters of undertaking in such form as
may from time to time be requested by and acceptable to the Mortgagee.

         (e) The Mortgagor hereby further undertakes that it shall deliver to
the Mortgagee certificates of insurance with respect to insurance policies or
other instruments or documents evidencing insurance coverage, naming the
Mortgagor as loss payee (or with undertakings acceptable to the Mortgagee in the
case of war risks and/or protection and indemnity clubs or associations).

         (f) All policies, binders, contracts, receipts and cover notes shall
upon request from the Mortgagee be delivered to the Mortgagee with evidence
satisfactory to it that the Mortgagor has kept up due and punctual payment of
all premiums, fees or contributions payable with respect to all risk coverages
required hereby and by the Credit Agreement. The Mortgagor shall notify and
request per notice of cancellation clauses acceptable to the Mortgagee all
insurers, clubs or associations (except war risk associations where seven (7)
calendar days advance notice shall be required) to agree in advance to notify
the Mortgagee at least fourteen (14) calendar days prior to the expiration or
cancellation of any risk coverage herein contemplated, and prior to any material
alteration to said coverage. The Mortgagor shall promptly extend or renew all
said risk coverage as may be necessary from time to time and will furnish proof
thereof to the Mortgagee no later than fourteen (14) calendar days (seven (7)
calendar days in the case of war risk

                                       11

insurance) prior to each date of expiration. The Mortgagee reserves the right to
make any payments, settlements or take any other action with the insurers,
associations or clubs to extend, maintain or renew any such insurance or risk
coverage and to avoid the cancellation or expiration of any insurance policy or
coverage herein provided for, but shall be under no obligation to do so. The
Mortgagee also reserves the right to approve or disapprove of any material
alteration to the said risk coverage, which approval shall not be unreasonably
withheld. All amounts so expended by the Mortgagee shall be payable by the
Mortgagor to the Mortgagee on demand and, until payment thereof is fully made,
shall be an obligation secured by this Mortgage forming a portion of the Secured
Obligations. The Mortgagor shall obtain the necessary consents or endorsements
in the instruments of coverage (or undertakings acceptable to the Mortgagee in
the case of war risks and/or protection and indemnity clubs or associations),
from the relevant insurers, clubs or associations where the Vessel may be
entered or covered, which the Mortgagee may deem necessary to obtain and
preserve the benefits of this Clause.

         (g) The Mortgagee shall have the right at its discretion, if it
considers that the risk coverage of the Vessel is not satisfactory, to demand
prompt compliance by the Mortgagor in obtaining any further risk coverage which
the Mortgagee may reasonably deem necessary or, in the absence of said prompt
compliance, to proceed itself to obtain the necessary additional insurance or
cover at the expense of the Mortgagor with the amount thereby invested to be
repayable on demand, secured by this Mortgage.

         (h) If any of the Insurances is part of a fleet coverage, the Mortgagor
shall procure that the insurers undertake to the Mortgagee that they shall
neither set-off against any claims in respect of the Vessel any premium(s) due
in respect of other vessels under such fleet coverage or any premium due for
other insurances, nor cancel any of the Insurances for reason of non-payment of
premiums for other vessels under such fleet coverage or premiums for other
insurances, and shall undertake to issue a separate policy or policies in
respect of the Insurances or any part thereof on or with respect to the Vessel,
if and when so requested by the Mortgagee.

         (i) Upon occurrence of an Event of Default, as provided for in Clause
20 hereof, the Mortgagee shall be entitled to settle any dispute with the
insurers, associations or clubs which may arise from their liability under the
respective insurance contracts or other instruments of coverage or on the amount
of compensation which they may be required to pay, with binding effects on the
rights of the Mortgagor under such insurance or cover. The Mortgagor shall
obtain the necessary consents from its insurers and war risks and protection and
indemnity clubs or associations in which the Vessel may be entered, and
inclusion, in the respective insurance policies and other instruments of
coverage or by way of an undertaking of the protection and indemnity
associations or clubs, acceptable to the Mortgagee, of any references which the
Mortgagee may deem necessary to obtain and preserve this option for its benefit.

to carry any contraband goods, to run blockades, to deviate into waters not
fully covered under any or all of the Insurances herein contemplated, to trade
or carry on business which is forbidden by international law or which is
otherwise illicit or to carry illicit or prohibited goods which may render the
Vessel subject to condemnation in a prize court, destruction, seizure or
confiscation. The Mortgagor shall obtain additional insurance coverage deemed
adequate in the opinion of the Mortgagee prior to employing the Vessel (i) in
any part of the world in which armed conflict, political violence, warfare,
civil unrest, insurrection, piracy or any other form of hostilities is
reasonably expected to occur or is occurring, (ii) in any zone that has been
declared a war zone by any government or by the Vessel's War Risk insurers, or

modifications, improvements or repairs, without obtaining the prior written
consent of the Mortgagee, unless such investment is necessary to maintain the
Vessel's class. In any event, the Mortgagor will keep the Mortgagee informed of
any major structural alteration or conversion to be made in the Vessel, and will
make sure that any such alteration or conversion is acceptable to the Mortgagee.

deletion or removal of the Vessel from the Registry of the Commissioner for
Maritime Affairs of St. Vincent and the Grenadines and/or change the nationality
of the Vessel without the prior written consent of the Mortgagee. The Mortgagor

consequences on the security hereby established, excepting normal wear and tear
to result from proper usage of the Vessel. The Mortgagor will keep the Vessel or
cause her to be kept in such state and condition as will entitle her to maintain
her current class status free of recommendations and notations affecting class
and qualifications and change of class.

laying claim to the Vessel through the Mortgagor, whether or not such claim or

Vessel or its master.

sale was or is unnecessary or improper and, notwithstanding any impropriety or
irregularity, any such sale shall, as regards the protection of the Vessel and
the purchaser's title thereto, be deemed valid and effectual; the only remedy of
the Mortgagor in respect of any alleged impropriety or irregularity shall be for
damages against or from the Mortgagee.

shall be concerned with the application of such moneys to any purpose of this
Mortgage or in any manner be answerable for any loss, mis-application or
non-application of any such moneys or any part thereof.

         (d) Upon completion of any non-judicial sale of the Vessel effected
under this Mortgage, the Mortgagee shall execute and deliver to the purchaser a
good and sufficient instrument in respect of the sale and transfer of the Vessel
and for that purpose the Mortgagor hereby irrevocably appoints (coupled with the
interest of the Mortgagee in this security) the Mortgagee to be its lawful
attorney in its name and stead to execute all instruments and other documents in
relation to any such sale PROVIDED ALWAYS that the Mortgagor shall, if so
requested by the Mortgagee or any purchaser of the Vessel, confirm any sale by

         certificates from filing or other registration officers, (g) all credit
         information, reports and memoranda relating thereto, and (h) all other

                                SECURITY INTEREST

         Section 2.01 Grant of Security Interest. To secure the prompt payment
and performance of the Secured Obligations and the performance by the Obligors
of their obligations under the Credit Documents, each Obligor hereby assigns and
grants to the Agent for the benefit of the Secured Parties a lien on and a
continuing security interest in, and right of set-off against,

                                       4
<PAGE>

such Obligor's right, title and interest in, to and under (all items described
in this Section 2.01, whether now owned or hereafter acquired by such Obligor
and wherever located and whether now owned or hereafter existing or arising,
collectively, the "Collateral"):

         (a) each and every Contract, all Contract Rights, Contract Documents
and Receivables associated with such Contracts and each and every document
granting security to any Obligor under any such Contract;

         (b) each and every Receivable;

         (c) all Inventory;

         (d) all Equipment;

         (e) all General Intangibles;

         (f) all Investment Property;

and in any other checking, savings, deposit or other account of any Obligor, all
monies, proceeds or sums due or to become due therefrom or thereon and all
documents (including, but not limited to passbooks, certificates and receipts)
evidencing all funds and investments held in such accounts;

         (i) any Governmental Requirements now or hereafter held by any Obligor
(except that any Governmental Requirement which would by its terms or under
applicable law become void, voidable, terminable or revocable by being subjected
to the Lien of this Security Agreement or in which a Lien is not permitted to be
granted under applicable law, is hereby excluded from such Lien to the extent
necessary so as to avoid such voidness, voidability, terminability or
revocability);

         (j) any right to receive a payment under any hedging agreement in
connection with a termination thereof;

         (k) without limiting the generality of the foregoing, all other
personal property, including but not limited to goods, Instruments, Chattel
Paper, Documents, credits, claims, demands and assets of such Obligor, whether

interests created pursuant to this Security Agreement; and

         (l) any and all additions, accessions and improvements to, all
substitutions and replacements for and all products and Proceeds of or derived

         It is expressly contemplated that additional property may from time to
time be pledged, assigned or granted by an Obligor (whether now or hereafter
party to the Credit Agreement) to the Agent as additional security for the
Secured Obligations, and the term "Collateral" shall be

                                       5
<PAGE>

deemed for all purposes hereof to include all such additional property, together
with all other property of the types described above related thereto.
Notwithstanding the foregoing, "Collateral" as used herein and the defined terms
used above in the description of Collateral shall not include any item of
property to the extent that an Obligor's grant of a security interest in such
Obligor's right, title and interest to such item of property is prohibited by
(or otherwise requires the consent to such grant under) an applicable
contractual obligation or requirement of law or would give any other Person the
right to terminate its obligations with respect to such item of property unless
any necessary consent to the grant of such a security interest (in the
reasonable judgement of both the Company and the Agent) has been obtained.

         Section 2.02 Security Interest Absolute. All rights of the Agent and
the Secured Parties hereunder shall be absolute and unconditional irrespective
of:

         (a) any change in the time, manner or place of payment of, or in any
other term of, all of any of the Secured Obligations, or any other amendment or
waiver of or any consent to any departure from any Credit Document;

         (b) any exchange, release or nonperfection of any other collateral, or
any release from, amendment to, waiver of or consent to departure from any
guaranty, for all or any of the Secured Obligations; or

         (c) to the fullest extent permitted by applicable law, any other
circumstance which might otherwise constitute a defense available to, or a
discharge of, any Obligor as a third party pledgor.

         Section 2.03 Power of Attorney. Each Obligor hereby constitutes and
appoints the Agent as such Obligor's attorney-in-fact, at such Obligor's cost
and expense, to exercise, in the Agent's discretion after the occurrence and
during the continuance of an Event of Default, all or any of the following
powers, which, being coupled with an interest, shall be irrevocable until all of
the Secured Obligations have been paid in full and the Commitments have been
terminated and the Letters of Credit have expired or been terminated or cash
collaterized as contemplated by the Credit Agreement:

         (a) to obtain and adjust insurance under insurance policies naming such
Obligor as an insured party;

         (b) to receive, take, endorse, sign, assign, deliver and collect, all
in the Agent's name or such Obligor's name, any and all checks, notes, drafts,
and other documents or instruments relating to the Collateral;

         (c) to ask, demand, collect, sue for, recover, compromise, receive and
give acquittance and receipts for moneys due and to become due under or in
connection with the Collateral;

         (d) to receive, open and dispose of all mail addressed to such Obligor
with respect to the Collateral which comes into the possession of the Agent and
to notify postal authorities to change the address for delivery thereof to such
address as the Agent designates, with a copy of such notice to such Obligor;

                                       6
<PAGE>

         (e) to request from account obligors of such Obligor, in the Obligor's
name or the Agent's name or that of the Agent's designee, information concerning
the Receivables and the amounts owing thereon;

         (f) to transmit to account obligors indebted on Receivables notice of
the Agent's interest therein;

         (g) to notify account obligors indebted on Receivables to make payment
directly to the Agent; and

         (h) to take or bring, in such Obligor's name or the Agent's name, all
steps, actions, suits or proceedings deemed by the Agent necessary or desirable
to enforce or effect collection of any of the Collateral or otherwise to enforce
compliance with the terms and conditions of any Contract or the rights of the
Agent with respect to any of the Collateral.

         Section 2.04 Obligors Remain Liable. Anything herein to the contrary
notwithstanding, (a) each Obligor shall remain liable to perform all of its
obligations under or with respect to the Collateral and to perform all duties
and obligations thereunder to the same extent as if this Security Agreement had
not been executed, (b) the exercise by the Agent of any of its rights hereunder
shall not release any Obligor from its duties or obligations under the Credit
Documents and (c) none of the Secured Parties shall have any obligation or
liability under the Credit Documents by reason of this Security Agreement, nor
shall the Agent or any Bank be obligated to perform any of the obligations or
duties of any Obligor thereunder or to take any action to collect or enforce any
claim for payment assigned hereunder.

                                   ARTICLE 3

                         REPRESENTATIONS AND WARRANTIES

         Each Obligor represents and warrants as of the date hereof and as of
the date of each Loan or Letter of Credit that:

         Section 3.01 Security Documents. This Security Agreement, together with
(x) the filing of financing statements in the offices set forth on Schedule 3.01
with respect to the named Obligor, (y) the delivery to the Agent or a third
party custodian of any Collateral in which a security interest is perfected by
possession, and (z) when executed and delivered, the execution and delivery by
the Obligors of an Account Control Agreement with respect to Collateral
consisting of Investment Property and deposit accounts (as defined in the UCC)
which are maintained by a financial institution in the United States (or any
similar agreement with respect to Investment Property and deposit accounts
maintained by a financial institution outside of the United States, to the
extent required by local law), is sufficient to create in favor of the Agent for
the benefit of the Secured Parties, as security for the payment and performance
of the Secured Obligations, a valid and enforceable perfected security interest
in and on all of the Collateral, superior to and prior to all Liens other than
Permitted Liens, except as such enforceability may be limited by (i) applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws from
time to time in effect that affect creditors' rights generally or (ii) general
principles of equity (regardless of whether enforceability is considered in a
proceeding in equity or at law).

                                       7
<PAGE>

         Section 3.02 Ownership of Collateral; No Liens. Except as otherwise
permitted by the Credit Agreement, each Obligor has good and valid title to its
Collateral free and clear of any adverse claim, lien, security interest, option
or other charge or encumbrance except for Permitted Liens, and such Obligor has
full right, power and authority to assign and grant a security interest in its
Collateral to the Agent. Each Obligor shall defend the Collateral against all
Liens, other than Permitted Liens, and demands of all Persons (other than the
Agent and the Banks) at any time claiming the same or any interest therein.

         Section 3.03 No Required Consents. No authorization, consent, approval
or other action by, and no notice to or filing with, any Governmental Authority
(other than the filing of financing statements, and notices to be delivered
pursuant to the U.S. Assignment of Claims Act in respect of any pledge of a
Receivable for which the account obligor is the U.S. government or any
department or agency thereof) is required for (i) the due execution, delivery
and performance by each Obligor of this Security Agreement, (ii) the grant of
the security interests granted herein, (iii) the perfection of such security
interests, or (iv) the exercise by the Agent of its rights and remedies under
this Security Agreement. Each Obligor which has pledged its rights to payment
under a contract subject to the U.S. Assignment of Claims Act hereby consents to
the Agent's sending of any notices required to comply with the U.S. Assignment
of Claims Act in respect of the Agent's security interest in Receivables arising
under such contract.

         Section 3.04 No Filings By Third Parties. Except as set forth in
Schedule 3.04, no financing statement or other public notice or recording
covering the Collateral is on file in any public office (other than any
financing statement or other public notice or recording naming Agent as the
secured party therein or which is to be released pursuant to relevant
documentation delivered to the Agent as of the date hereof), and, except as
otherwise permitted by the Credit Agreement, no Obligor will execute any
financing statement or other public notice or recording (other than any
financing statement or other public notice or recording naming Agent as the
secured therein) so long as any of the Secured Obligations are outstanding.

         Section 3.05 No Name Changes. Except as described in the last sentence
of this Section, each Obligor has not, during the preceding five years, entered
into any contract, agreement, security instrument or other document using a name
other than, or been known by or otherwise used any name other than the name
reflected on the signature pages to this Security Agreement. Each name reflected
on the signature pages to this Security Agreement is the exact legal name of
such Obligor under its jurisdiction of formation. MSI Energy Services Inc.
("MSI") was formed by amalgamation with Willbros Canada Acquisition Corporation,
and prior to April 1999, MSI was known as "Alberta Surface Systems Limited".

         Section 3.06 Location of Obligors; Agent and Collateral. Each Obligor's
registered office, principal place of business and its chief executive office is
located as the address set forth on Schedule 3.06(A) hereto. The originals of
all Contracts, Contract Documents and documents evidencing Receivables of each
Obligor, and the only original books of accounts and records concerning the
Collateral of such Obligor, are kept at such Obligor's chief executive office.
The equipment owned by each of the Obligors named on Schedule 3.06(B) is located
as indicated next to such Obligor's name on such Schedule, or as otherwise
notified to the Agent prior to any move of such equipment to any new location.
Except for the Obligors

                                       8
<PAGE>

named on Schedule 3.06(B), no other Obligor is the owner of any equipment. The
Agent's address is set forth on Schedule 3.06(C).

         Section 3.07 Collateral. All statements or other information provided
by the Obligors to Agent with respect to the Collateral is correct and complete
in all material respects. The delivery at any time by any Obligor (whether nor
or hereafter party to the Credit Agreement) to Agent of additional Collateral or
of additional descriptions of Collateral shall constitute a representation and
warranty by such Obligor to Agent hereunder that the representations and
warranties of this Article 3 are correct insofar as they would pertain to such
Collateral or the descriptions thereof.

                                   ARTICLE 4

                            COVENANTS AND AGREEMENTS

         Each Obligor will at all times comply with the covenants and agreements
contained in this Article 4 until all of the Secured Obligations have been paid
in full and the Commitments have been terminated and the Letters of Credit shall
have expired or been terminated or cash collateralized as contemplated by the
Credit Agreement.

         Section 4.01 Change in Location of Collateral or Obligor's Name. Each
Obligor shall not establish a new location for its principal place of business
or chief executive office or change its name or carry on any business under any
name other than the name reflected on the signature pages to this Security
Agreement until such Obligor has given the Agent not less than thirty (30) days'
prior written notice of its intention to do so, clearly describing such new
location or specifying such new name, as the case may be, and providing such
other information in connection therewith as the Agent may reasonably request.

         Section 4.02 Financing Statements and Registrations. Each Obligor
agrees to sign and deliver to the Agent such financing statements or
registrations, in form suitable to reflect the security interests granted
hereunder, as the Agent reasonably determines are necessary or desirable to
establish and maintain a valid, enforceable, perfected security interest in the
Collateral, all in accordance with the laws which govern perfection of the
security interests hereunder. The Obligors will pay any applicable filing fees
and related expenses. Each Obligor authorizes the Agent to file in such
jurisdictions as determined by the Agent any such financing or continuation
statements, and amendments thereto, relating to all or any part of the
Collateral without the signature of such Obligor where permitted by applicable
law. Upon the request of any Obligor, the Agent shall promptly deliver, or cause
to be delivered, to such Obligor copies of any such statements or amendments.

         Section 4.03 Documents; Collateral in Possession of Third Parties. Each
Obligor shall deliver and pledge to the Agent any and all Investment Property,
Instruments, Documents, Contract Documents or other Collateral or documents
evidencing Collateral (in each case to the extent a security interest may be
perfected by possession), endorsed and/or accompanied by such instruments of
assignment and transfer and consents as the Agent may request, all in such form
and substance as the Agent may request in order to perfect the security
interests granted by this Security Agreement in any Collateral, at the expense
of the Obligors. If any Collateral is at any time in the possession or control
of any warehouseman, bailee, agent or independent

                                       9
<PAGE>

contractor, the Obligors shall notify such Person of the Agent's security
interest in such Collateral. Upon the Agent's request, the Obligors shall
instruct any such Person to hold all such Collateral for the Agent's account
subject to an Obligor's instructions, or, if an Event of Default shall have
occurred, subject to the Agent's instructions.

         Section 4.04 Control of U.S. Investment Property. Each Obligor shall
take any and all actions reasonably requested by the Agent to ensure that the
Agent has "control" (within the meaning of Section 8-106 of the UCC) of
Collateral constituting Investment Property and deposit accounts (as defined in
the UCC) located in the United States, including, but not limited to, the
execution of an Account Control Agreement.

         Section 4.05 Reimbursement of Expenses. Each Obligor hereby assumes all
liability for the Collateral, the security interests created hereunder and any
use, possession, maintenance, management, enforcement or collection of any or
all of the Collateral. Each Obligor agrees to indemnify and hold the Agent
harmless from and against and covenants to defend the Agent against any and all
losses, damages, claims, costs, penalties, liabilities and expenses, including,
without limitation, court costs and attorneys' fees, incurred because of,
incident to, or with respect to the Collateral (including, without limitation,
any use, possession, maintenance or management thereof, or any injuries to or
deaths of persons or damage to property), except where due to the gross
negligence or willful misconduct of the Agent. All amounts for which any Obligor
is liable pursuant to this Section 4.05 shall be due and payable by the Obligors
to the Agent upon demand. If the Obligors fail to make such payment upon demand
(or if demand is not made due to an injunction or stay arising from bankruptcy
or other proceedings) and the Agent pays such amount, the same shall be due and
payable by the Obligors to the Agent, plus interest thereon from the date of the
Agent's demand (or from the date of the Agent's payment if demand is not made
due to such proceedings) at the Default Rate.

         Section 4.06 Insurance Proceeds. In addition to the insurance
requirements set forth in the Credit Agreement, each policy for property damage
insurance maintained by any Obligor shall name the Agent for the benefit of the
Secured Parties as loss payee for all amounts payable by the insurer with
respect to property damage or losses of at least $1,000,000 per occurrence.

         Section 4.07 Taxes. Each Obligor will pay promptly when due all
property and other taxes, assessments and governmental charges or levies imposed
upon, and all claims (including without limitation, claims for labor, materials
and supplies) against such Obligor's Equipment and Inventory; provided, however,
that such Obligor shall not be required to pay or discharge any such tax,
assessment, charge or claim that is being contested in good faith and by proper
proceedings and as to which appropriate reserves are being maintained, unless
and until any Lien resulting therefrom attaches to such Obligor's property and
becomes enforceable against such Obligor's other creditors.

         Section 4.08 Further Assurances. Upon the request of the Agent, each
Obligor shall (at such Obligor's expense) execute and deliver all such
assignments, certificates, financing statements or other documents and give
further assurances and do all other acts and things as the Agent may reasonably
request to perfect the Agent's interest in the Collateral or to

                                       10
<PAGE>

protect, enforce or otherwise effect the Agent's rights and remedies hereunder,
including without limitation, obtaining any authorization, consent or approval
of, or filing any notice with, any governmental authority or regulatory body of
any jurisdiction as the Agent may reasonably request (to the extent such actions
are both cost-effective and practical).

                                    ARTICLE 5
              SPECIAL PROVISIONS CONCERNING RECEIVABLES, CONTRACTS,
                            INSTRUMENTS AND ACCOUNTS

         Section 5.01 Maintenance of Records. Each Obligor will keep and
maintain, at its own cost and expense, satisfactory and complete records of its
Receivables, including but not limited to records of all payments received and
all credits granted thereon, and each Obligor will make the same available to
the Agent for inspection at any reasonable time after reasonable notice as the
Agent may reasonably request. If upon the occurrence and during the continuation
of an Event of Default, the Agent so directs, each Obligor shall, at its own
cost and expense, deliver all tangible evidence of its Receivables (including
without limitation all documents evidencing the Receivables) and books and
records that the Agent may reasonably request to the Agent or to its
representatives (copies of which evidence and books and records may be retained
by such Obligor) at such times as the Agent may reasonably request. If, upon the
occurrence and during the continuation of an Event of Default, the Agent
directs, each Obligor shall legend in form and substance reasonably satisfactory
to the Agent, the Receivables and Contracts and Contract Documents, as well as
books, records and documents of such Obligor evidencing or pertaining to the
Receivables, with an appropriate references to the fact that such items of
Collateral have been assigned to the Agent as security and that the Agent has a
security interest therein.

         Section 5.02 Payments Under Contracts and Receivables.

         (a) Notice to Obligors under Contracts. Each Obligor further agrees and
confirms that, upon the occurrence and continuation of an Event of Default and
upon the request of the Agent, each Obligor will notify each party to any
Contracts of the assignment thereof to the Agent, instruct each of them that all
payments due or to become due and all amounts payable to such Obligor under such
Contracts shall, until the Secured Obligations are paid in full and the
Commitments have been terminated, be made to the Bank Accounts for application
in accordance with the Credit Agreement, and, if requested by the Agent and
reasonably feasible, obtain a written consent and acknowledgement from them in
form and substance reasonably acceptable to the Agent. Unless notified to the
contrary by the Agent, such Obligor shall, at its own cost and expense, enforce
collection of any amounts payable under the Contracts.

         (b) Payments to Agent. Until the Secured Obligations are paid in full
and the Commitments have been terminated, if any Obligor shall receive directly
from any party to the Contracts or from any account debtor or other obligor
under any Receivable any payments under the Contracts or the Receivables, such
Obligor shall receive (and hereby acknowledges that it is receiving) such
payments in trust for the benefit of the Secured Parties, shall segregate such
payments from other funds of such Obligor, and shall forthwith transmit and
deliver such

                                       11
<PAGE>

payments to the Agent for the benefit of the Secured Parties in the same form as
so received (with any necessary endorsement) for application in accordance with
the Credit Agreement.

         (c) Direction to Account Parties, Contracting Parties, etc. The
Obligors agree that, upon the occurrence and during the continuation of an Event
of Default, each Obligor shall be bound by any collection, compromise,
forgiveness, extension or other action taken by the Agent with respect to the
Receivables and the Contracts. Upon the occurrence and during the continuation
of an Event of Default, without notice to or assent from any Obligor, the Agent
may apply any or all amounts then or thereafter deposited with it in accordance
with the provisions of the Credit Agreement. The costs and expenses (including
reasonable attorneys' fees) of collection, whether incurred by an Obligor or the
Agent, shall be borne by such Obligor.

         Section 5.03 Cash Collateral Account.

         (a) On the Closing Date, the Agent shall establish with CLNY an account
in New York (such account herein called the "Cash Collateral Account") for the
purposes described in the Credit Agreement.

         (b) The Obligors shall have no right to withdraw or to cause CLNY or
the Agent to withdraw any funds deposited in, or transfer any financial assets
or security entitlements in, the Cash Collateral Account. CLNY recognizes the
Agent as the sole party entitled to give any instructions with respect to the
Cash Collateral Account and agrees to comply with the Agent's instructions and
entitlement orders. CLNY will not agree with any third party that CLNY will
comply with entitlement orders concerning the Cash Collateral Account originated
by such third party without the prior written consent of the Agent and the
Obligors. CLNY will treat all property held by it in the Cash Collateral Account
as financial assets under Article 8 of the UCC.

         (c) At any time and from time to time, upon the Agent's request, each
Obligor promptly shall execute and deliver any and all such further instruments
and documents as may be necessary, appropriate or desirable in the Agent's
judgment to obtain the full benefits (including perfection and priority) of the
security interest created or intended to be created by this Security Agreement
and of the rights and powers granted in this Security Agreement and the other
Credit Documents. The Obligors shall not create or suffer to exist any Lien on
any amounts or investments held in the Cash Collateral Account other than the
Lien granted under this Security Agreement.

         (d) The Agent shall (i) apply any funds in the Cash Collateral Account
to the payment of Secured Obligations as set forth in the Credit Agreement and
(ii) after the date on which the Commitments shall have terminated, apply any
such funds remaining in the Cash Collateral Account first, to pay any unpaid
Secured Obligations then outstanding and then, to refund any remaining amount to
the Obligors.

         (e) Except as otherwise provided herein, the Company, no more than once
in any calendar month, may direct CLNY to invest the funds held in the Cash
Collateral Account (so long as the aggregate amount of such funds exceeds any
relevant minimum investment requirement

                                       12
<PAGE>

as determined by the Agent) in one or more types of Cash Equivalents in Dollars
with maturities no longer than thirty (30) days, pending application of such
funds on account of Secured Obligations. In the absence of any such direction
from the Company, CLNY shall invest the funds in securities issued or fully
guaranteed by the U.S. Government. The balance of the funds shall be invested in
Eurodollar time deposits constituting Cash Equivalents. CLNY shall neither
accept nor comply with any entitlement order from any Obligor withdrawing any
financial assets from the Cash Collateral Account nor deliver any such financial
assets to any Obligor nor pay any amounts owing from CLNY to any Obligor with
respect to the Cash Collateral Account without the specific prior written
consent of the Agent. CLNY will comply with entitlement orders originated by the
Agent concerning the Cash Collateral Account without further consent by any
Obligor and regardless of whether an Event of Default shall have occurred.

         (f) At such time as the Agent delivers a written notice to CLNY which
states that an Event of Default has occurred and is continuing and that the
Agent is thereby exercising exclusive control over the Cash Collateral Account
(the "Notice of Exclusive Control"), CLNY will immediately cease complying with
instructions or entitlement orders concerning the Cash Collateral Account
originated by the Company or any of its representatives until such time as CLNY
receives written notice from the Agent that the right of the Company to effect
trades from the Cash Collateral Account have been reinstated by the Agent. CLNY
shall have no responsibility or liability to any Obligor for complying with a
Notice of Exclusive Control or complying with entitlement orders concerning the
Cash Collateral Account originated by the Agent. CLNY shall have no duty to
investigate or make any determination as to whether an Event of Default exists
and shall comply with a Notice of Exclusive Control even if it believes that an
Event of Default does not exist. Neither this Agreement nor any other Credit
Document imposes or creates any obligation or duty on CLNY other than those
expressly set forth herein.

         (g) All investments of funds held in the Cash Collateral Account shall
be made in the Agent's name for the benefit of the Secured Parties. The Obligors
recognize that any losses or taxes with respect to such investments shall be
borne solely by the Obligors, and the Obligors agree to indemnify the Agent, the
Issuing Bank, and the Banks for, and hold each such Person harmless from and
against, any such losses or taxes other than losses arising from the gross
negligence or willful misconduct of the Agent. The Agent may liquidate any
investment held in the Cash Collateral Account in order to apply the proceeds of
such investment on account of Secured Obligations then due and payable without
regard to whether such investment has matured and without liability for any
penalties or other fees incurred (with respect to which each Obligor hereby
agrees to reimburse the Agent) as a result of such application. All items of
income, gain, expense and loss recognized in the Cash Collateral Account for
U.S. persons shall be reported to the Internal Revenue Service and all state and
local taxing authorities under the name and taxpayer identification number of
the appropriate Obligor.

         (h) The Agent will advise the Company on a monthly basis of the results
of the investments of the funds held in the Cash Collateral Account based on the
daily activity thereof.

                                       13

         (i) The Obligors shall pay to CLNY the fees customarily charged by CLNY
with respect to the maintenance of accounts similar to the Cash Collateral
Account.

         (j) This Agreement supplements any deposit agreement or similar
agreement which any one or more of the Obligors and CLNY have entered or may
enter into, notwithstanding any integration clause therein. In the event of a
conflict between this Agreement and any other agreement between an Obligor and
CLNY relating to the Cash Collateral Account, the terms of this Agreement will
prevail. Regardless of any provision in such deposit or similar agreement, New
York shall be deemed to be CLNY's location for the purposes of this Agreement
and the perfection and priority of the Agent's security interest in the Cash
Collateral Account. All matters relating to the Cash Collateral Account shall be
governed by the laws of the State of New York.

         The rights and powers granted herein to the Agent have been granted in
order to perfect its security interests, are powers coupled with an interest,
and will neither be affected by the bankruptcy of any Obligor nor by the lapse
of time.

                                   ARTICLE 6

                       RIGHTS, DUTIES AND POWERS OF AGENT

         The following rights, duties and powers of the Agent are applicable
irrespective of whether an Event of Default has occurred and is continuing:

         Section 6.01 Cumulative and Other Rights. The rights, powers and
remedies of the Agent hereunder are in addition to every other right, power and
remedy given under any other Credit Document or now or hereafter existing at law
or in equity. The exercise by the Agent of any one or more of the rights, powers
and remedies herein shall not be construed as a waiver of any other rights,
powers and remedies, including, without limitation, any other rights of set-off.

         Section 6.02 Disclaimer of Certain Duties.

         (a) The powers conferred upon the Agent by this Security Agreement are
to protect its interest in the Collateral and shall not impose any duty upon the
Agent to exercise any such powers. Each Obligor hereby agrees that the Agent
shall not be liable for, nor shall the indebtedness evidenced by the Secured
Obligations be diminished by, the Agent's delay or failure to collect upon,
foreclose, sell, take possession of or otherwise obtain value for the
Collateral.

         (b) The Agent shall be under no duty whatsoever to make or give any
presentment, notice of dishonor, protest, demand for performance, notice of
non-performance, notice of intent to accelerate, notice of acceleration, or
other notice or demand in connection with any Collateral or the Secured
Obligations, or to take any steps necessary to preserve any rights against any
obligor or other Person. Each Obligor waives any right of marshaling in respect
of any and all Collateral, and waives any right to require the Agent to proceed
against any obligor or other Person, exhaust any Collateral or enforce any other
remedy which the Agent now has or may hereafter have against any obligor or
other Person.

                                       14
<PAGE>

         Section 6.03 Modification of Obligations; Other Security. Each Obligor
waives (i) any and all notice of acceptance, creation, modification,
rearrangement, renewal or extension for any period of any instrument executed by
any Obligor in connection with the Secured Obligations and (ii) any defense of
any Obligor by reason of disability, lack of authorization, cessation of the
liability of any Obligor or for any other reason. Each Obligor authorizes the
Agent, without notice or demand and without any reservation of rights against
such Obligor and without affecting such Obligor's liability hereunder or for the
Secured Obligations, from time to time to (x) take and hold other property,
other than the Collateral, as security for the Secured Obligations, and
exchange, enforce, waive and release any or all of the Collateral, (y) apply the
Collateral in the manner permitted by this Security Agreement, and (z) renew,
extend for any period, shorten the maturity, amend or modify, supplement,
enforce, compromise, settle, waive or release the obligations of any Obligor or
any instrument or agreement of such other Person with respect to any or all of
the Secured Obligations or Collateral.

         Section 6.04 Enforcement of Contract Rights. Upon the occurrence and
during the continuation of an Event of Default (but not prior to such time), the
Agent may enforce all remedies, rights, powers and privileges of an Obligor
under any or all of the Contracts and Contract Documents and/or substitute
itself or any nominee or trustee in lieu of an Obligor as party to any of the
Contracts and Contract Documents and may notify the obligated party of any
Contract Right (such Obligor hereby agreeing to deliver any such notice at the
request of the Agent) that all payments and performance by such obligated party
under the relevant Contract or Contract Document shall be made or rendered to
the Agent or such other Person as the Agent may designate in writing, with a
copy to such Obligor.

                                   ARTICLE 7

                                    REMEDIES

         Section 7.01 Remedies; Obtaining the Collateral Upon Default. Upon the
occurrence and during the continuation of an Event of Default, the Agent shall
have all rights and remedies of a secured party under the laws which govern the
creation, perfection or enforcement of the security interests hereunder to
enforce this Security Agreement and the security interests contained herein,
including, without limitation, the right to appoint by instrument in writing any
Person as a receiver or as a receiver and manager (collectively, the
"Receiver"). The Agent may from time to time, remove or replace a Receiver, or
make application to any court of competent jurisdiction for the appointment of a
Receiver. Any Receiver appointed by the Agent will (for purposes relating to the
responsibility for the Receiver's acts or omissions) be considered to be the
Obligor's agent. The Agent may from time to time fix the Receiver's remuneration
and the Obligor will pay to the Agent on demand the amount of such remuneration.
The Agent will not be liable to the Obligor or any other Person in connection
with appointing or not appointing a Receiver or in connection with a Receiver's
actions or omissions. Without limiting the generality of the foregoing, the
Agent may, upon the occurrence and during the continuation of an Event of
Default, in addition to its other rights and remedies hereunder or under
applicable law, may take any or all of the following actions to the extent
permitted by applicable law:

                                       15

<PAGE>
(a)   personally, or by Receiver, trustees or attorneys, immediately take
      possession of the Collateral or any part thereof, from an Obligor or any
      other Person who then has possession of any part thereof with or without
      notice or process of applicable law, and for that purpose may enter upon
      such Obligor's premises where any of the Collateral is located and remove
      the same and use in connection with such removal any and all services,
      supplies, aids and other facilities of such Obligor;

(b)   instruct the obligor or obligors on any agreement, instrument or other
      obligation constituting the Collateral to make any payment required by the
      terms of such instrument, agreement or obligation directly to the Agent or
      Receiver;

(c)   take possession of the Collateral or any part thereof, by directing the
      Obligors in writing to deliver the Collateral to the Agent at any place or
      places designated by the Agent, in which event each Obligor shall at its
      own expense:

(i)   forthwith cause the same to be moved to the place or places so designated
      by the Agent or Receiver and there be delivered to the Agent or Receiver;

(ii)  store and keep any Collateral so delivered to the Agent or Receiver at
      such place or places pending further action by the Agent or Receiver as
      provided in Section 6.2;

(iii) while the Collateral shall be so stored and kept, provide such guards and
      maintenance services as shall be necessary to protect the same and to
      preserve and maintain them in good condition; and

(iv)  render any equipment unusable that may be included in the Collateral, or,
      at the Agent's or Receiver's request, the Obligor will render it unusable.

         To the extent permitted by applicable law, each Obligor's obligations
to deliver the Collateral is of the essence of this Security Agreement and,
accordingly, upon application to a court of equity having jurisdiction, the
Agent shall be entitled to obtain a decree requiring specific performance by any
Obligor of said obligations. In any event, each Obligor shall bear the risk of
accidental loss or damage to or diminution in value of the Collateral, and the
Agent shall have no liability whatsoever for failure to obtain or maintain
insurance, nor to determine whether any insurance ever in force is adequate as
to amount or as to risk insured.

Section 7.02 Remedies; Disposition of Collateral. Any Collateral of which the
      Agent or Receiver has taken possession under or pursuant to this Security
      Agreement and any other Collateral, whether or not so possessed by the
      Agent or Receiver, may, upon the occurrence and during the continuation of
      an Event of Default, to the extent permitted by applicable law, be sold or
      leased, in one or more sales or leases and in one or more parcels, or
      otherwise disposed of in any other commercially reasonable manner as the
      Agent or Receiver may elect, in a public or private transaction, at any
      location as deemed reasonable by the Agent or Receiver (including, without
      limitation, any Obligor's premises), either for cash or credit or for
      future delivery at such price as the Agent or Receiver may deem fair, and
      (unless prohibited by the UCC, as adopted in any applicable jurisdiction,
      or by any similar Canadian legislation as may be applicable, including the
      Personal Property Security Act (Alberta) and the Civil Enforcement Act
      (Alberta)) the Agent or Receiver may be the purchaser of any or

                                       16
<PAGE>
      all Collateral so sold and may apply upon the purchase price therefore any
      Secured Obligations secured hereby. Any such sale or transfer by the Agent
      or Receiver either to itself or to any other Person shall be absolutely
      free from any claim of right by any Obligor, including any equity or right
      of redemption, stay or appraisal which any Obligor has or may have under
      any rule of law, regulation or statute now existing or hereafter adopted.
      Upon any such sale or transfer, the Agent or Receiver shall have the right
      to deliver, assign and transfer to the purchaser or transferee thereof the
      Collateral so sold or transferred. It shall not be necessary that the
      Collateral or any part thereof be present at the location of any such sale
      or transfer. The Agent or Receiver may, at its discretion, provide for a
      public sale, and any such public sale shall be held at such time or times
      within ordinary business hours and at such place or places as the Agent or
      Receiver may fix in the notice of such sale. The Agent or Receiver shall
      not be obligated to make any sale pursuant to any such notice. The Agent
      or Receiver may, without notice or publication, adjourn any public or
      private sale by announcement at any time and place fixed for such sale,
      and such sale may be made at any time or place to which the same may be so
      adjourned. In the event any sale or transfer hereunder is not completed or
      is defective in the opinion of the Agent or Receiver, such sale or
      transfer shall not exhaust the rights of the Agent or Receiver hereunder,
      and the Agent or Receiver shall have the right to cause one or more
      subsequent sales or transfers to be made hereunder. In the event that any
      of the Collateral is sold or transferred on credit, or is to be held by
      the Agent or Receiver for future delivery to a purchaser or transferee,
      the Collateral so sold or transferred may be retained by the Agent or
      Receiver until the purchase price or other consideration is paid by the
      purchaser or transferee thereof, but in the event that such purchaser or
      transferee fails to pay for the Collateral so sold or transferred or to
      take delivery thereof, the Agent or Receiver shall incur no liability in
      connection therewith. If only part of the Collateral is sold or
      transferred such that the Secured Obligations remain outstanding (in whole
      or in part), the Agent's or Receiver's rights and remedies hereunder, as
      applicable, shall not be exhausted, waived or modified, and the Agent or
      Receiver, as applicable, is specifically empowered to make one or more
      successive sales or transfers until all the Collateral shall be sold or
      transferred and all the Secured Obligations are paid. In the event that
      the Agent or Receiver, as applicable, elects not to sell the Collateral,
      the Agent or Receiver, as applicable, retains its rights to lease or
      otherwise dispose of or utilize the Collateral or any part or parts
      thereof in any manner authorized or permitted by law or in equity, and to
      apply the proceeds of the same towards payment of the Secured Obligations.
      Each and every method of disposition of the Collateral described in this
      subsection shall constitute disposition in a commercially reasonable
      manner.

Section 7.03 Liability for Deficiency. If any sale or other disposition of
      Collateral by the Agent or any other action of the Agent hereunder results
      in reduction of the Secured Obligations, such action will not release any
      Obligor from its liability to the Secured Parties for any unpaid Secured
      Obligations, including costs, charges and expenses incurred in the
      liquidation of Collateral, together with interest thereon, and the same
      shall be immediately due and payable to the Agent at the Agent's address
      set forth in the opening paragraph hereof.

Section 7.04 Reasonable Notice. If any applicable provision of any law requires
      the Agent to give reasonable notice of any sale or disposition or other
      action, each Obligor hereby agrees that ten (10) days' prior written
      notice shall constitute reasonable notice thereof. Such

                                       17
<PAGE>
      notice, in the case of public sale, shall state the time and place fixed
      for such sale and, in the case of private sale, the time after which such
      sale is to be made.

Section 7.05 Non-judicial Enforcement. The Agent may enforce its rights
      hereunder without prior judicial process or judicial hearing, and to the
      extent permitted by law each Obligor expressly waives any and all legal
      rights which might otherwise require the Agent to enforce its rights by
      judicial process.

                                   ARTICLE 8
                            MISCELLANEOUS PROVISIONS

Section 8.01 Notices. Any notice required or permitted to be given under or in
      connection with this Security Agreement shall be given in accordance with
      Section 13.2 of the Credit Agreement.

Section 8.02 Amendments and Waivers. The Agent's acceptance of partial or
      delinquent payments or any forbearance, failure or delay by the Agent in
      exercising any right, power or remedy hereunder shall not be deemed a
      waiver of any obligation of any Obligor, or of any right, power or remedy
      of the Agent; and no partial exercise of any right, power or remedy shall
      preclude any other or further exercise thereof. The Agent may remedy any
      Event of Default hereunder or in connection with the Secured Obligations
      without waiving the Event of Default so remedied. Each Obligor hereby
      agrees that if the Agent agrees to a waiver of any provision hereunder, or
      an exchange of or release of the Collateral, or the addition or release of
      any Obligor or other Person, any such action shall not constitute a waiver
      of any of the Agent's other rights or of such Obligor's obligations
      hereunder. This Security Agreement may be amended only by an instrument in
      writing executed jointly by each Obligor and the Agent and may be
      supplemented only by documents delivered or to be delivered in accordance
      with the express terms hereof.

Section 8.03 Successors and Assigns. This Security Agreement shall be binding
      upon and inure to the benefit of the Obligors, the Agent and the Secured
      Parties and their respective successors and assigns.

Section 8.04 Survival. All agreements, statements, representations and
      warranties made by each Obligor herein or in any certificate or other
      instrument delivered by any Obligor or on its behalf under this Security
      Agreement shall be considered to have been relied upon by the Agent and
      the Secured Parties and shall survive the execution and delivery of this
      Security Agreement and the other Credit Documents regardless of any
      investigation made by the Agent or any Secured Party or on their behalf.

Section 8.05 Headings Descriptive. The headings of the various Articles,
      sections and paragraphs of this Security Agreement are for convenience of
      reference only, do not constitute a part hereof and shall not affect the
      meaning or construction of any provision hereof.

Section 8.06 Severability. Any provision hereof that is prohibited or
      unenforceable in any jurisdiction shall, as to such jurisdiction, be
      ineffective to the extent of such prohibition or

                                       18
<PAGE>
      unenforceability without invalidating the remaining provisions hereof and
      without affecting the validity or enforceability of any provision in any
      other jurisdiction.

Section 8.07 Jurisdiction and Enforcement.

(a)   This Security Agreement shall be governed by and construed in accordance
      with the laws of the State of New York.

(b)   Section 13.14 of the Credit Agreement shall apply to this Security
      Agreement.

Section 8.08 Redelivery of Collateral. Any Collateral that is sold, transferred
      or otherwise disposed of in accordance with Section 9.2 of the Credit
      Agreement shall automatically be released from the Lien of this Security
      Agreement without delivery of any instrument or performance of any further
      act by any Person, and upon any such release, the Agent will, at the
      Obligors' sole expense, execute and deliver to the applicable Obligors
      such documents as such Obligor shall reasonably request to evidence such
      release. If any sale or transfer of Collateral by the Agent results in
      full satisfaction of the Secured Obligations, and after such sale or
      transfer and discharge there remains a surplus of proceeds, the Agent will
      deliver to the Obligors such excess proceeds in a commercially reasonable
      time; provided, however, that the Agent shall not be liable for any
      interest, cost or expense in connection with any delay in delivering such
      proceeds to the Obligors.

Section 8.09 Continuing Security Agreement.

(a)   Except as may be expressly applicable pursuant to Section 9-505 of the
      UCC, no action taken or omission to act by the Agent hereunder, including,
      without limitation, any action taken or inaction pursuant to Section 6.02,
      shall be deemed to constitute a retention of the Collateral in
      satisfaction of the Secured Obligations or otherwise to be in full
      satisfaction of the Secured Obligations, and the Secured Obligations shall
      remain in full force and effect, until the Agent shall have applied
      payments (including, without limitation, collections from Collateral)
      towards the Secured Obligations in the full amount then outstanding or
      until such subsequent time as is hereinafter provided in subsection (b)
      below.

(b)   To the extent that any payments on the Secured Obligations or proceeds of
      the Collateral are subsequently invalidated, declared to be fraudulent or
      preferential, set aside or required to be repaid to a trustee, debtor in
      possession, receiver or other Person under any bankruptcy law, common law
      or equitable cause, then to such extent the Secured Obligations so
      satisfied shall be revived and continue as if such payment or proceeds had
      not been received by the Agent, and the Agent's security interests,
      rights, powers and remedies hereunder shall continue in full force and
      effect. In such event, this Security Agreement shall be automatically
      reinstated if it shall theretofore have been terminated pursuant to
      Section 8.11.

Section 8.10 Agent May Perform. If any Obligor fails to perform any agreement
      contained herein, the Agent may itself perform, or cause the performance
      of, such agreement, and the expenses of the Agent incurred in connection
      therewith shall be payable by the Obligors.

Section 8.11 Termination. The grant of a security interest hereunder and all of
      the Agent's rights, powers and remedies in connection therewith shall
      remain in full force and effect until

                                       19
<PAGE>
      all Secured Obligations have been satisfied or irrevocably paid in full
      and the Commitments have expired or are terminated and all Letters of
      Credit have expired or terminated. Upon the complete payment of the
      Secured Obligations (other than any indemnity which is not yet due and
      payable) and the compliance by the Obligors with all covenants and
      agreements hereof, the Agent, at the written request and expense of the
      Obligors, will release, reassign and transfer the Collateral to the
      respective Obligor (without recourse and without any representation or
      warranty of any kind) such of the Collateral of such Obligor as may be in
      possession of the Agent and has not theretofore been sold or otherwise
      applied or released pursuant to this Security Agreement, and shall take
      such other action as any Obligor may reasonably request to effectuate the
      foregoing. Notwithstanding the foregoing, the reimbursement and
      indemnification provisions of Sections 4.05 and the provisions of Section
      8.13 shall survive the termination of this Security Agreement.

Section 8.12 Counterparts; Effectiveness. This Security Agreement may be
      executed in two or more counterparts. Each counterpart is deemed an
      original, but all such counterparts taken together constitute one and the
      same instrument. This Security Agreement becomes effective upon the
      execution hereof by the Obligors and delivery of the same to the Agent,
      and it is not necessary for the Agent to execute any acceptance hereof or
      otherwise signify or express its acceptance hereof.

Section 8.13 Indemnity. The Obligors shall pay on demand to the Agent the amount
      of any and all reasonably expenses, including without limitation the
      reasonably fees and expenses of its counsel and of any experts and agents,
      that the Agent may incur in connection with (i) the administration of this
      Security Agreement, (ii) the custody, preservation, use or operation of,
      or the sale of, collection from or other realization upon, any of the
      Collateral, (iii) the exercise or enforcement of any of the rights of the
      Agent hereunder or (iv) the failure by any Obligor to perform or observe
      any of the provisions hereof.

Section 8.14 New Obligors. Each of the parties hereto acknowledges and agrees
      that any Designated Subsidiary which executes an Election to Participate
      after the date of this Security Agreement shall automatically, and without
      further action hereunder by any party hereto, become an Obligor hereunder
      and under the Credit Agreement for all purposes.

Section 8.15 Certain Panama Procedures. Each Obligor hereby appoints and
      empowers Arias, Fabrega & Fabrega, attorneys at law with offices in the
      City of Panama, Republic of Panama, and each of the said firm's partners,
      to appear before a notary public in the City of Panama, Republic of
      Panama, and in the name and on behalf of the Obligors to request that the
      notary file a copy of this Security Agreement in the notary's protocol and
      to subsequently file a copy of the corresponding notarial deed at the
      Public Registry Office in order to create a general pledge on or in
      respect of each Panamanian Obligor's assets located outside of the
      Republic of Panama, in accordance with Article 829A of the Commercial Code
      of the Republic of Panama, and to take all further steps as shall be
      necessary from time to time to perfect the security interest on or in
      respect of such assets, including, at the request of the Agent, adding or
      deleting Obligors and any amendments that may be agreed upon by the
      Obligors and the Agent.

                                    consent, shall be void. The preceding
                                    sentence shall not limit the right of the

                                    one and the same instrument.

                        SEPARATION AGREEMENT AND RELEASE

        THIS SEPARATION AGREEMENT AND RELEASE ("Agreement") is made and entered
into this 30th day of May, 2002, by and between WILLBROS USA, INC. ("Employer")
and LARRY J. BUMP ("Employee").

                                   WITNESSETH:

        WHEREAS, Employee is or was employed by Employer; and

        WHEREAS, Employee will retire from his employment with Employer
effective May 31, 2002 ("Retirement Date"); and

        WHEREAS, Employer and Employee wish to achieve a final and amicable
resolution of all issues related to their employment relationship;

        NOW, THEREFORE, for and in consideration of the mutual covenants and
promises set forth below, as well as other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties agree as
follows:

1.      EMPLOYEE'S RETIREMENT.  Employee and Employer confirm and agree that
        Employee will retire from employment with Employer as of the Retirement
        Date and that the employment relationship which existed between Employee
        and Employer and/or any of Employer's affiliated companies will cease as
        of the Retirement Date. However, nothing contained herein shall prevent
        or interfere with the ability of the parties to enter into future
        agreements for Employee to provide consulting services and advice to
        Employer or Employer's affiliates on an independent contractor basis
        ("Subsequent Agreement"). In addition, it is anticipated that Employee
        will continue to serve as a non-employee Class III member of the Board
        of Directors of Willbros Group, Inc. ("WGI"), Employer's parent company,
        after the Retirement Date and that Employee will also serve as Chairman
        of such Board and as a member of various committees of such Board.
        Except as provided in any Subsequent Agreement or in policies which
        apply generally to non-employee members of the WGI Board ("Board
        Policies"), all of Employer's obligations to Employee on or after the
        Retirement Date are set forth herein. Accordingly, except as otherwise
        provided herein, in a Subsequent Agreement or in Board Policies,
        Employer shall have no further obligations whatsoever to Employee after
        the Retirement Date. Employer shall cause its personnel records to
        reflect that Employee retired from employment with Employer effective on
        the Retirement Date.

2.      PRIOR AGREEMENTS SUPERSEDED. Except as otherwise specifically provided
        herein, this Agreement supersedes and replaces all other prior
        agreements, written or oral, relating to Employee's employment with
        Employer and/or any of Employer's affiliated companies.

<PAGE>

3.      2002 SALARY AND BONUS. Employee will continue or continued to receive
        his current, regular salary through the Retirement Date, less applicable
        withholding taxes. In addition, on the Retirement Date, Employee will
        receive a bonus for the calendar year 2002 in the amount of Five Hundred
        Thousand U.S. Dollars (U.S.$500,000), less applicable withholding taxes.

4.      MANAGEMENT INCENTIVE PLAN. Prior to the Retirement Date, Employee
        participated in the Willbros USA, Inc. Management Incentive Plan dated
        January 1, 1996 ("Incentive Plan"). Employee acknowledges that the
        Incentive Plan terminated December 31, 1998 and that Employee is not
        entitled to any further payments or benefits under the Incentive Plan.

5.      MEDICAL INSURANCE CONTINUATION. Employee acknowledges that Employer no
        longer provides benefits under the Retiree Medical Plan which it
        previously maintained and that neither Employee nor Employee's
        dependents are entitled to any benefits thereunder. If Employee is not
        entitled to Medicare benefits, Employee will be entitled to continue
        participation for a limited period of time in Employer's Group Medical
        Plan, Group Dental Plan and/or Executive Medical Plan under the
        Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA").
        Detailed information concerning the costs and procedures applicable to
        such insurance coverage will be provided separately by Employer.

6.      LIFE INSURANCE CONVERSION. Employee has the right to convert Employee's
        life insurance coverage under Employer's Group Life Plan and dependent
        life insurance coverage obtained by the Employee under Employer's
        Dependent Life Plan to individual life insurance policies. Conversion
        forms and premium rates applicable to such conversion programs will be
        provided separately by the relevant insurer.

7.      PENSION PLAN. As a vested participant in the Willbros USA, Inc. Pension
        Plan ("Pension Plan") previously maintained by Employer for the benefit
        of eligible employees, Employee was entitled to certain retirement
        benefits in accordance with the Pension Plan termination procedure
        approved by the Internal Revenue Service (the "Pension Plan Termination
        Procedure"). Under the Pension Plan Termination Procedure, Employee
        elected to receive a lump sum distribution of benefits and has received
        such distribution. Employee acknowledges that no further benefits are
        payable to Employee under the Pension Plan or the Pension Plan
        Termination Procedure.

8.      EXECUTIVE BENEFIT RESTORATION PLAN. Prior to the Retirement Date,
        Employee also participated in the Willbros USA, Inc. Executive Benefit
        Restoration Plan ("Restoration Plan"). Effective January 22, 2001, the
        Restoration Plan was terminated and Employee received a distribution of
        all benefits to which Employee was entitled under the Restoration Plan.
        Employee releases the

                                       2
<PAGE>

        Employer, the Restoration Plan Trust, the Restoration Plan Trustee, and
        the Restoration Plan administrators from any further claims for benefits
        under the Restoration Plan.

9.      INCENTIVE STOCK OPTIONS. Employee is vested in certain incentive stock
        options and certain non-qualified stock options provided by WGI,
        pursuant to the Willbros Group, Inc. 1996 Stock Plan ("Stock Plan").
        Nothing in this Agreement shall affect any rights or obligations of
        Employee or WGI under the Incentive Stock Option Agreement or the
        Non-Qualified Stock Option Agreements entered into between Employee and
        WGI pursuant to the Stock Plan. Employee acknowledges that any of
        Employee's incentive stock options awarded under the Stock Plan which
        are exercised more than three (3) months after the Retirement Date will
        be treated as non-qualified stock options for U.S. federal income tax
        purposes.

10.     EMPLOYER INVESTMENT PLAN. Employee is fully vested in Employer's 401(k)
        Investment Plan ("Investment Plan"). Employee has the option of
        receiving a lump-sum distribution of Employee's total account balance in
        the Investment Plan, transferring such account balance to another
        tax-qualified plan or to an Individual Retirement Account or leaving
        such account balance in the Investment Plan. Election forms and detailed
        information concerning Employee's options with respect to Employee's
        account balance in the Investment Plan will be provided separately by
        Employer.

11.     DIRECTOR AND OFFICER MATTERS. Employee shall resign from all employee,
        officer, director and committee member positions which Employee holds
        with Employer or any affiliate of Employer effective as of the
        Retirement Date, except that Employee shall not resign from Employee's
        position as Chairman of the WGI Board of Directors or as a Class III
        member of the WGI Board of Directors. Nothing in this Agreement shall
        affect any of Employee's rights or obligations with respect to
        indemnification or director and officer liability insurance coverage to
        which Employee is entitled or subject in his capacity as a former
        director and officer of Employer, a former officer of WGI, a continuing
        Class III non-employee director of WGI or a former officer or director
        of certain WGI affiliates, whether under that certain Indemnification
        Agreement between WGI and Employee dated June 27, 1996, or otherwise.

12.     ACCRUED VACATION PAY. On the Retirement Date, Employee shall receive
        Thirty Six Thousand Two Hundred Twenty One and 59/100 U.S. Dollars
        (U.S.$36,221.59), less applicable payroll tax withholding, as
        compensation for all of Employee's accrued vacation time through the
        Retirement Date.

13.     OTHER BENEFITS. Except as specifically set forth herein, all employment
        benefits previously made available to Employee by Employer or any of its
        affiliates, including, without limitation, those made available under
        Employer's Executive Compensation Program, shall cease to be available
        to Employee as of the Retirement Date. Employee acknowledges that he is
        not entitled to receive any

                                       3
<PAGE>

        compensation, severance payment or retirement enhancement payment under
        the Employer's 1999 or 2000 Reduction-In-Force Plans or WGI's Severance
        Protection Plan.

14.     LUMP SUM PAYMENT. On the Effective Date (as defined in Paragraph 20
        below), Employer shall pay to Employee a lump sum amount of Five Hundred
        Thousand U.S. Dollars (U.S.$500,000), less applicable payroll tax
        withholding, in consideration of the release specified below and the
        acknowledgements, waivers, representations and undertakings specified
        herein.

15.     RELEASE.

        (a) Except for the obligations of Employer specifically set forth in
        this Agreement or referenced in this Agreement as continuing
        obligations, Employee fully and forever relieves, releases, and
        discharges Employer, WGI and all of their respective representatives,
        officers, directors, shareholders, predecessors, successors, parents,
        subsidiaries, operating units, affiliates, divisions, employees and

        obligations, promises, acts, agreements, costs, expenses, damages,
        actions, and causes of action, whether in law or in equity, whether
        known or unknown, suspected or unsuspected, arising from Employee's
        employment with and termination from Employer, including but not limited
        to any and all claims pursuant to Title VII of the Civil Rights Act of
        1964, 42 U.S.C. Section 2000e, et seq., as amended by the Civil Rights
        Act of 1991, which prohibits discrimination in employment based on race,

                                       4
<PAGE>

        (b) Except for the obligations of Employee specifically set forth in
        this Agreement or referenced in this Agreement as continuing
        obligations, Employer, on behalf of itself and its affiliates, fully and
        forever relieves, releases, and discharges Employee, from any and all
        claims, debts, liabilities, demands, obligations, promises, acts,
        agreements, costs, expenses, damages, actions, and causes of action,
        whether in law or in equity, whether known or unknown, suspected or
        unsuspected, arising from Employee's employment with and termination
        from Employer. Employer is not waiving any rights or claims that may
        arise after the Retirement Date.

16.     CONFIDENTIALITY. The following confidentiality obligations are in
        addition to those which will apply to Employee in Employee's continuing
        capacity as Chairman of the WGI Board of Directors and a Class III
        member of the WGI Board of Directors after the Retirement Date. To the
        extent such other obligations are of longer duration or more strict than
        the obligations set forth below, such other obligations shall supercede
        the obligations set forth below. For a period of two (2) years after the
        Retirement Date, Employee shall not, except as otherwise required by
        law, furnish, disclose or make accessible to any person, entity or
        government authority, any knowledge, trade secrets, customer
        information, supplier information, plans, opportunities, procedures,
        data, techniques or other information relating to the businesses or
        finances of Employer or any of its affiliates. The prohibitions set
        forth in the preceding sentence shall not apply, however, to information
        in the public domain (but only if the same becomes part of the public
        domain through a means other than a disclosure prohibited hereunder). In
        addition, Employee shall continue to comply fully with the use and
        disclosure restrictions set forth in all third party confidentiality
        agreements entered into by the Employer or its affiliates on or prior to
        the Retirement Date to the extent such third party agreements are known
        to Employee.

17.     REMEDIES. The parties recognize that, because of the nature of the
        subject matter of Paragraph 16 above, it would be impracticable and
        extremely difficult to determine the actual damages suffered by Employer
        in the event of a material breach of Employee's obligations thereunder.
        Accordingly, if Employee commits a material breach, or threatens to
        commit a material breach, of any of the provisions of Paragraph 16,
        Employer or any of its successors or assigns shall give Employee written
        notice of such violation and, if Employee has not cured such violation
        or otherwise ceased to act in violation of Paragraph 16 within ten (10)
        days after the giving of such notice, Employer or any of its successors
        or assigns shall have the following rights and remedies:

        (a)       to have the provisions of Paragraph 16 specifically enforced
                  by any court having equity jurisdiction, without the posting
                  of bond or other security, it being acknowledged and agreed by
                  Employee that any such breach or threatened breach will cause
                  irreparable injury to Employer and that an injunction may be
                  issued against Employee to stop or prevent any such breach or
                  threatened breach; and

                                       5
<PAGE>

        (b)       to recover such actual damages as Employer or its affiliates
                  may incur as a result of such breach or threatened breach.

        The curing of a violation of the requirements of Paragraph 16 shall not
        preclude Employer from seeking the recovery of its actual damages
        resulting from such violation.

18.     INDEPENDENT LEGAL ADVICE. Employee acknowledges that he has had the
        opportunity to be represented by independent legal counsel of his choice
        with respect to the advisability of signing this Agreement and providing
        the releases, waivers, acknowledgements, representations and
        undertakings specified herein, and with respect to his rights and
        obligations under the terms of this Agreement.

19.     KNOWLEDGE OF CONTENTS. Both parties acknowledge that they have carefully
        read this Agreement and that the contents hereof are known and
        understood by them. This Agreement is signed freely by each party
        hereto.

20.     REVIEW AND REVOCATION PERIOD. Employee acknowledges that he has been
        extended a period of forty-five (45) days within which to consider this
        Agreement. For a period of seven (7) days following Employee's
        execution of the Agreement, Employee may revoke this Agreement by
        notifying Employer, in writing, of his desire to do so. From and after
        the date which is seven (7) days after Employee's execution of this
        Agreement (the "Effective Date"), this Agreement shall be binding and
        enforceable.

21.     OBLIGATION TO RETURN FUNDS. In the event Employee exercises his right
        to revocation set forth in Section 20 above, Employee shall immediately
        return to Employer all amounts, if any, paid to Employee as
        consideration under this Agreement. The duty to return funds under this
        Agreement shall survive the revocation of the Agreement and shall
        constitute a separately enforceable obligation between Employee and
        Employer.

22.     NO ADMISSION OF LIABILITY. This Agreement and compliance with this
        Agreement shall not be construed as an admission by Employer or
        Employee of any liability whatsoever, or as an admission by Employer of
        any violation of the rights of Employee or any other person, or any
        violation of any order, law, statute, duty or contract.

23.     SEVERABILITY. In the event that any provision of this Agreement should
        be held to be void, voidable, or unenforceable, the remaining portions
        hereof shall remain in full force and effect.

24.     GOVERNING LAW. This Agreement will be interpreted and enforced in
        accordance with the laws of the State of Texas.

                                       6

25.     ENTIRETY AND INTEGRATION. Upon the execution hereof by all of the
        parties hereto, this Agreement shall constitute a single, integrated
        contract expressing the entire agreement of the parties relative to the
        subject matter hereof and, except as otherwise specifically noted
        herein, supersedes all prior negotiations, understandings and/or
        agreements, if any, of the parties. No covenants, agreements,
        representations, or warranties of any kind whatsoever have been made by
        any party hereto, except as specifically set forth in this Agreement.

        IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the date first mentioned above.
