                      AMENDED AND RESTATED CREDIT AGREEMENT

         THIS AMENDED AND RESTATED CREDIT AGREEMENT (this "Agreement") is made
and entered into as of January 2, 2004 (the "Effective Date"), by and among
OCEANEERING INTERNATIONAL, INC., a Delaware corporation (together with its
permitted successors and assigns, herein called the "Borrower"); each of the
lenders which is or may from time to time become a party hereto (individually, a
"Lender" and, collectively, the "Lenders"); HSBC BANK USA, as Documentation
Agent; COMERICA BANK, as Syndication Agent and WELLS FARGO BANK, N.A., a
national banking association, as administrative agent and lead arranger (in such
capacity, together with its successors in such capacity, the "Administrative
Agent" or "Agent").

         The Borrower, certain of the Lenders and Wells Fargo Bank, N.A., as
agent ("Existing Agent") previously entered into that certain Credit Agreement
dated as of July 1, 2003 (as amended prior to the date hereof, the "Existing
Credit Agreement").

         The parties hereto desire to amend and restate such Existing Credit
Agreement in its entirety and refinance the "Obligations" thereunder by
providing (a) an initial Aggregate Commitment of $250,000,000 and (b) an option
for the Borrower to increase such Aggregate Commitment to an amount not
exceeding $300,000,000, subject to the terms and conditions hereof.

         Accordingly, the parties hereto agree to amend and restate the Existing
Credit Agreement in its entirety as follows:

SECTION 1. DEFINITIONS.

         Section 1.1. Certain Defined Terms.

         In this Agreement, terms defined above shall have the meanings ascribed
to them above. Unless a particular term, word or phrase is otherwise defined or
the context otherwise requires, capitalized terms, words and phrases used herein
or in the Loan Documents (as hereinafter defined) have the following meanings
(all definitions that are defined in this Agreement or in the Loan Documents in
the singular have the same meanings when used in the plural and vice versa):

         "Additional Interest" means the aggregate of all amounts accrued or
paid pursuant to the Notes or any of the other Loan Documents (other than
interest on the Notes at the Stated Rate) which, under applicable laws, are or
may be deemed to constitute interest on the indebtedness evidenced by the Notes
or any other amounts owing under any Loan Document.

         "Adjusted LIBOR" means, with respect to each Interest Period applicable
to a LIBOR Borrowing, a rate per annum equal to the quotient, expressed as a
percentage, of (a) LIBOR with respect to such Interest Period divided by (b)
1.0000 minus the Eurodollar Reserve Requirement in effect on the first day of
such Interest Period.

         "Administrative Questionnaire" means an Administrative Questionnaire in
a form supplied by the Agent.

         "Affiliate" means any Person controlling, controlled by or under common
control with any other Person. For purposes of this definition, "control"
(including "controlled by" and

                                      -1-
<PAGE>

"under common control with") means the possession, directly or indirectly, of
the power to direct or cause the direction of the management and policies of
such Person, whether through the ownership of voting securities or otherwise.

         "Aggregate Commitments" means the aggregate amount of the Commitments
of all the Lenders, which initially shall be $250,000,000, but which may be
increased pursuant to Section 2.9 hereof.

         "Agreement" means this Credit Agreement, as it may from time to time be
amended, modified, restated or supplemented.

statements of Borrower and its Subsidiaries, including all notes thereto, which

fiscal year relating thereto and a consolidated income statement and a
consolidated statement of cash flows for such fiscal year, all setting forth in
comparative form the corresponding figures from the previous fiscal year, all
prepared in conformity with GAAP in all material respects, and accompanied by
the opinion of independent certified public accountants of recognized national
standing, which shall state that such financial statements present fairly in all
material respects the consolidated financial position of the applicable Persons
as of the date thereof and the results of consolidated operations of the
applicable Persons for the period covered thereby in conformity with GAAP. As
long as Borrower files an annual report on Form 10-K with the Securities and
Exchange Commission, such report and related financial statements, including
notes thereto and opinion of independent certified public accountants, included
thereon shall be considered the "Annual Financial Statements".

         "Approved Fund" means any Fund that is administered or managed by (a) a
Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an

have determined (which determination shall be prima facie evidence of the
correctness thereof) that it is unable to ascertain the Federal Funds Rate for
any reason, including, without limitation, the inability or failure of Agent to
obtain sufficient quotations in accordance with the terms hereof, the Base Rate
shall, until the circumstances giving rise to such inability no longer exist, be
the lesser of (a) the Prime Rate plus the then applicable Margin Percentage from
time to time in effect or (b) the Ceiling Rate.

         "Base Rate Borrowing" means that portion of the principal balance of
the Loans at any time bearing interest at the Base Rate.

time, as to current and future balances, implement any other ceiling under the
Texas Finance Code by notice to Borrower, if and to the extent applicable to any
Lender and permitted by the Texas Finance Code. Without notice to Borrower or
any other person or entity, the Ceiling Rate shall automatically fluctuate
upward and downward as and in the amount by which such maximum nonusurious rate
of interest permitted by applicable law fluctuates. Notwithstanding any choice
of law set forth herein or in any other Loan Document, to the maximum extent
permitted under applicable laws, any Lender may elect to have the usury laws of
another jurisdiction apply to the Note and the Loans held by such Lender.

         "Change of Control" shall be deemed to have occurred if any person (as
such term is used in Section 13(d) and Section 14(d)(2) of the Exchange Act as
in effect on the date of the Closing) or related persons constituting a group

hereafter in effect, together with all regulations, rulings and interpretations

not exceeding) the amount, if any, set forth opposite such Lender's name on the
signature pages hereof under the caption "Commitment", or otherwise provided for

to time pursuant to Section 2.4 hereof or increased pursuant to Section 2.9).

         "Commitment Percentage" means, as to any Lender, the percentage

Commitment (or if the

                                      -3-

         hereby irrevocably authorizes the Swing Line Lender to so request on
         its behalf), that each Lender make a Loan in an amount equal to such
         Lender's Commitment Percentage of the amount of Swing Line

                                      -21-
<PAGE>

         Loans then outstanding. Such request shall be made in writing (which
         written request shall be deemed to be a notice of borrowing for
         purposes hereof) and in accordance with the requirements of Section
         3.1, subject to the unutilized portion of the Aggregate Commitments and
         the conditions set forth in Section 5.2. The Swing Line Lender shall
         furnish the Borrower with a copy of the Request for Extension of Credit
         promptly after delivering such request to the Agent. Each Lender shall
         make an amount equal to its Commitment Percentage of the amount
         specified in such Request for Extension of Credit available to the
         Agent in immediately available funds for the account of the Swing Line
         Lender at the Principal Office whereupon, subject to Section
         2.2(c)(ii), each Lender that so makes funds available shall be deemed
         to have made a Revolving Loan to the Borrower in such amount. The Agent
         shall remit the funds so received to the Swing Line Lender.

                           (ii) If for any reason any Swing Line Loan cannot be
         refinanced by such a Revolving Borrowing in accordance with Section
         2.2(c)(i), the Request for Extension of Credit submitted by the Swing
         Line Lender as set forth herein shall be deemed to be a request by the
         Swing Line Lender that each of the Lenders fund its risk participation
         in the relevant Swing Line Loan and each Lender's payment to the Agent
         for the account of the Swing Line Lender pursuant to Section 2.2(c)(i)
         shall be deemed payment in respect of such participation.

                           (iii) Each Lender's obligation to make Loans or to
         purchase and fund risk participations in Swing Line Loans pursuant to
         this Section 2.2(c) shall be absolute and unconditional and shall not
         be affected by any circumstance, including (A) any set-off,
         counterclaim, recoupment, defense or other right which such Lender may
         have against the Swing Line Lender, the Borrower or any other Person
         for any reason whatsoever, (B) the occurrence or continuance of a
         Default, or (C) any other occurrence, event or condition, whether or
         not similar to any of the foregoing; provided, however, that each
         Lender's obligation to make Loans pursuant to this Section 2.2(c) is
         subject to the conditions set forth in Section 5.2. No such funding of
         risk participations shall relieve or otherwise impair the obligation of
         the Borrower to repay Swing Line Loans, together with interest as
         provided herein.

                  (d) Repayment of Participations. At any time after any Lender
has purchased and funded a risk participation in a Swing Line Loan, if the Swing
Line Lender receives any payment on account of such Swing Line Loan, the Swing
Line Lender will distribute to such Lender its Commitment Percentage of such
payment (appropriately adjusted, in the case of interest payments, to reflect
the period of time during which such Lender's risk participation was funded) in
the same funds as those received by the Swing Line Lender.

                  (e) Interest for Account of Swing Line Lender. The Swing Line
Lender shall be responsible for invoicing the Borrower for interest on the Swing
Line Loans. Until each Lender funds its Loan or risk participation pursuant to
this Section 2.2 to refinance such Lender's Commitment Percentage of any Swing
Line Loan, interest in respect of such Commitment Percentage shall be solely for
the account of the Swing Line Lender.

                  (f) Payments Directly to Swing Line Lender. The Borrower shall
make all payments of principal and interest in respect of the Swing Line Loans
directly to the Swing Line Lender.

         Section 2.3 Letters of Credit.

                  (a) The Letter of Credit Commitment.

                           (i) Subject to the terms and conditions set forth
         herein, (A) the L/C Issuer agrees, in reliance upon the agreements of
         the other Lenders set forth in this Section 2.3, (1) from time to time
         on any Business Day during the period from the Effective Date until the
         Maturity Date, to issue Letters of Credit for the account of the
         Borrower, and to amend Letters of Credit previously issued by it, in
         accordance with subsection (b) below, and (2) to honor drafts under the
         Letters of Credit; and (B) the Lenders severally agree to participate
         in Letters of Credit issued for the account of the Borrower; provided
         that the L/C Issuer shall not be obligated to make any L/C Credit
         Extension with respect to any Letter of Credit, and no Lender shall be
         obligated to participate in any Letter of Credit if as of the date of
         such L/C Credit Extension, (x) the Total Outstandings would exceed the
         Aggregate Commitments, (y) the aggregate Outstanding Amount of the
         Revolving Loans of any Lender, plus such Lender's Commitment Percentage
         of the Outstanding Amount of all L/C Obligations, plus such Lender's
         Commitment Percentage of the Outstanding Amount of all Swing Line Loans
         would exceed such Lender's Commitment, or (z) the Outstanding Amount of
         the L/C Obligations would exceed the Letter of Credit Sublimit. Within
         the foregoing limits, and subject to the terms and conditions hereof,
         the Borrower's ability to obtain Letters of Credit shall be fully
         revolving, and accordingly the Borrower may, during the foregoing
         period, obtain Letters of Credit to replace Letters of Credit that have
         expired or that have been drawn upon and reimbursed. The Existing L/C
         Obligations are refinanced under this Agreement and, to the extent then
         outstanding, shall be included in any calculation of L/C Obligations,
         and Existing L/Cs shall for all purposes constitute Letters of Credit
         issued under this Agreement.

                           (ii) The L/C Issuer shall be under no obligation to
         issue any Letter of Credit if:

                                    (1) any order, judgment or decree of any
                           Governmental Authority or arbitrator shall by its
                           terms purport to enjoin or restrain the L/C Issuer
                           from issuing such Letter of Credit, or any Legal
                           Requirement applicable to the L/C Issuer or directive
                           (whether or not having the force of law) from any
                           Governmental Authority with jurisdiction over the L/C
                           Issuer shall prohibit, the issuance of letters of
                           credit generally or such Letter of Credit in
                           particular or shall impose upon the L/C Issuer with
                           respect to such Letter of Credit any restriction,
                           reserve or capital requirement (for which the L/C
                           Issuer is not otherwise compensated hereunder) not in
                           effect on the Effective Date, or shall impose upon
                           the L/C Issuer any unreimbursed loss, cost or expense
                           which was not applicable on the Effective Date and
                           which the L/C Issuer in good faith deems material to
                           it;

                                    (2) the expiry date of such requested
                           commercial Letter of Credit would occur more than 180
                           days after the date of issuance;

                                      -23-
<PAGE>

                                    (3) the expiry date of such requested Letter
                           of Credit would occur after the Letter of Credit
                           Expiration Date, unless all the Lenders have approved
                           such expiry date;

                                    (4) the issuance of such Letter of Credit
                           would violate one or more policies of the L/C Issuer;
                           or

                                    (5) such Letter of Credit is in an initial
                           amount less than $200,000, in the case of a
                           commercial Letter of Credit, or $500,000, in the case
                           of a standby Letter of Credit, or is denominated in a
                           currency other than Dollars.

                           (iii) The L/C Issuer shall be under no obligation to
         amend any Letter of Credit if (A) the L/C Issuer would have no
         obligation at such time to issue such Letter of Credit in its amended
         form under the terms hereof, or (B) the beneficiary of such Letter of
         Credit does not accept the proposed amendment to such Letter of Credit.

                  (b) Procedures for Issuance and Amendment of Letters of
Credit.

                           (i) Each Letter of Credit shall be issued or amended,
         as the case may be, upon the request of the Borrower delivered to the
         L/C Issuer (with a copy to the Agent) in the form (which may be
         electronic using the L/C Issuer's Trade Services Online product) of a
         Letter of Credit Application, appropriately completed and signed by a
         Responsible Officer. Such Letter of Credit Application must be received
         by the L/C Issuer and the Agent not later than 11:00 a.m. pacific time
         at least two Business Days (or such later date and time as the L/C
         Issuer may agree in a particular instance in its sole discretion) prior
         to the proposed issuance date or date of amendment, as the case may be.
         In the case of a request for an initial issuance of a Letter of Credit,
         such Letter of Credit Application shall specify in form and detail
         reasonably satisfactory to the L/C Issuer: (A) the proposed issuance
         date of the requested Letter of Credit (which shall be a Business Day);
         (B) the amount thereof; (C) the expiry date thereof; (D) the name and
         address of the beneficiary thereof; (E) the documents to be presented
         by such beneficiary in case of any drawing thereunder; (F) the full
         text of any certificate to be presented by such beneficiary in case of
         any drawing thereunder; and (G) such other matters as the L/C Issuer
         may require. In the case of a request for an amendment of any
         outstanding Letter of Credit, such Letter of Credit Application shall
         specify in form and detail reasonably satisfactory to the L/C Issuer
         (A) the Letter of Credit to be amended; (B) the proposed date of
         amendment thereof (which shall be a Business Day); (C) the nature of
         the proposed amendment; and (D) such other matters as the L/C Issuer
         may require.

                           (ii) Promptly after receipt of any Letter of Credit
         Application, the L/C Issuer will confirm with the Agent (by telephone
         or in writing) that the Agent has received a copy of such Letter of
         Credit Application from the Borrower and, if not, the L/C Issuer will
         provide the Agent with a copy thereof. Upon receipt by the L/C Issuer
         of confirmation from the Agent that the requested issuance or amendment
         is permitted in accordance with the terms hereof, then, subject to the
         terms and conditions hereof, the L/C Issuer shall, on the requested
         date, issue a Letter of Credit for the account of the Borrower or enter
         into the applicable amendment, as the case may be, in each case in
         accordance with the L/C Issuer's usual and customary business
         practices. Immediately

                                      -24-
<PAGE>

         upon the issuance of each Letter of Credit, each Lender shall be deemed
         to, and hereby irrevocably and unconditionally agrees to, purchase from
         the L/C Issuer a risk participation in such Letter of Credit in an
         amount equal to the product of such Lender's Commitment Percentage
         times the amount of such Letter of Credit.

                           (iii) Promptly after its delivery of any Letter of
         Credit or any amendment to a Letter of Credit to an advising bank with
         respect thereto or to the beneficiary thereof, the L/C Issuer will also
         deliver to the Borrower and the Agent a true and complete copy of such
         Letter of Credit or amendment.

                  (c) Drawings and Reimbursements; Funding of Participations.

                           (i) Upon receipt from the beneficiary of any Letter
         of Credit of any notice of a drawing under such Letter of Credit, the
         L/C Issuer shall notify the Borrower and the Agent thereof. Not later
         than 11:00 a.m. pacific time on the date of any payment by the L/C
         Issuer under a Letter of Credit (each such date, an "Honor Date"), the
         Borrower shall reimburse the L/C Issuer through the Agent in an amount
         equal to the amount of such drawing. If the Borrower fails to so
         reimburse the L/C Issuer by such time, the Agent shall promptly notify
         each Lender of the Honor Date, the amount of the unreimbursed drawing
         (the "Unreimbursed Amount"), and the amount of such Lender's Commitment
         Percentage thereof. In such event, the Borrower shall be deemed to have
         requested a Base Rate Borrowing to be disbursed on the Honor Date in an
         amount equal to the Unreimbursed Amount, without regard to the minimum
         and multiples specified in Section 2.1 for the principal amount of
         Revolving Loans, but subject to the amount of the unutilized portion of
         the Aggregate Commitments and without regard to the fulfillment of the
         conditions set forth in Section 5.2. Any notice given by the L/C Issuer
         or the Agent pursuant to this Section 2.3(c)(i) may be given by
         telephone if immediately confirmed in writing; provided that the lack
         of such an immediate confirmation shall not affect the conclusiveness
         or binding effect of such notice.

                           (ii) Each Lender (including the Lender acting as L/C
         Issuer) shall upon any notice pursuant to Section 2.3(c)(i) make funds
         available to the Agent for the account of the L/C Issuer at the
         Principal Office in an amount equal to its Commitment Percentage of the
         Unreimbursed Amount not later than 1:00 p.m. pacific time on the
         Business Day specified in such notice by the Agent, whereupon, subject
         to the provisions of Section 2.3(c)(iii), each Lender that so makes
         funds available shall be deemed to have made a Revolving Loan to the
         Borrower in such amount. The Agent shall remit the funds so received to
         the L/C Issuer.

                           (iii) With respect to any Unreimbursed Amount that is
         not fully refinanced by a Base Rate Borrowing because the conditions
         set forth in Section 5.2 cannot be satisfied or for any other reason,
         the Borrower shall be deemed to have incurred from the L/C Issuer an
         L/C Borrowing in the amount of the Unreimbursed Amount that is not so
         refinanced, which L/C Borrowing shall be due and payable on demand
         (together with interest) and shall bear interest at the Past Due Rate.
         In such event, each Lender's payment to the Agent for the account of
         the L/C Issuer pursuant to Section 2.3(c)(ii) shall be deemed payment
         in respect of its participation in such L/C Borrowing and shall
         constitute an L/C Advance from such Lender in satisfaction of its
         participation obligation under this Section 2.3.

                                      -25-
<PAGE>

                           (iv) Until each Lender funds its Revolving Loan or
         L/C Advance pursuant to this Section 2.3(c) to reimburse the L/C Issuer
         for any amount drawn under any Letter of Credit, interest in respect of
         such Lender's Commitment Percentage of such amount shall be solely for
         the account of the L/C Issuer.

                           (v) Each Lender's obligation to make Revolving Loans
         or L/C Advances to reimburse the L/C Issuer for amounts drawn under
         Letters of Credit, as contemplated by this Section 2.3(c), shall be
         absolute and unconditional and shall not be affected by any
         circumstance, including (A) any set-off, counterclaim, recoupment,
         defense or other right which such Lender may have against the L/C
         Issuer, the Borrower or any other Person for any reason whatsoever; (B)
         the occurrence or continuance of a Default, or (C) any other
         occurrence, event or condition, whether or not similar to any of the
         foregoing; provided, however, that each Lender's obligation to make
         Revolving Loans pursuant to this Section 2.3(c) is subject to the
         conditions set forth in Section 5.2 (other than delivery by the
         Borrower of a Request for Extension of Credit). No such making of an
         L/C Advance shall relieve or otherwise impair the obligation of the
         Borrower to reimburse the L/C Issuer for the amount of any payment made
         by the L/C Issuer under any Letter of Credit, together with interest as
         provided herein.

                           (vi) If any Lender fails to make available to the
         Agent for the account of the L/C Issuer any amount required to be paid
         by such Lender pursuant to the foregoing provisions of this Section
         2.3(c) by the time specified in Section 2.3(c)(ii), the L/C Issuer
         shall be entitled to recover from such Lender (acting through the
         Agent), on demand, such amount with interest thereon for the period
         from the date such payment is required to the date on which such
         payment is immediately available to the L/C Issuer at a rate per annum
         equal to the lesser of (x) the Federal Funds Rate and (y) the Ceiling
         Rate from time to time in effect. A certificate of the L/C Issuer
         submitted to any Lender (through the Agent) with respect to any amounts
         owing under this clause (vi) shall be conclusive absent manifest error.

                  (d) Repayment of Participations.

                           (i) At any time after the L/C Issuer has made a
         payment under any Letter of Credit and has received from any Lender
         such Lender's L/C Advance in respect of such payment in accordance with
         Section 2.3(c), if the Agent receives for the account of the L/C Issuer
         any payment in respect of the related Unreimbursed Amount or interest
         thereon (whether directly from the Borrower or otherwise, including
         proceeds of Cash Collateral applied thereto by the Agent), the Agent
         will distribute to such Lender its Commitment Percentage thereof
         (appropriately adjusted, in the case of interest payments, to reflect
         the period of time during which such Lender's L/C Advance was
         outstanding) in the same funds as those received by the Agent.

                           (ii) If any payment received by the Agent for the
         account of the L/C Issuer pursuant to Section 2.3(c)(i) is required to
         be returned under any of the circumstances described herein (including
         pursuant to any settlement entered into by the L/C Issuer in its
         discretion), each Lender shall pay to the Agent for the account of the
         L/C Issuer its Commitment Percentage thereof on demand of the Agent,
         plus interest thereon from the date of such demand to the date such
         amount is returned by such Lender, at a

                                      -26-
<PAGE>

         rate per annum equal to the lesser of (x) the Federal Funds Rate and
         (y) the Ceiling Rate from time to time in effect.

                  (e) Obligations Absolute. The obligation of the Borrower to
reimburse the L/C Issuer for each drawing under each Letter of Credit and to
repay each L/C Borrowing shall be absolute, to the fullest extent permitted
under applicable law, unconditional and irrevocable, and shall be paid strictly
in accordance with the terms of this Agreement under all circumstances,
including the following:

                           (i) any lack of validity or enforceability of such
         Letter of Credit, this Agreement, or any other agreement or instrument
         relating thereto;

                           (ii) the existence of any claim, counterclaim,
         set-off, defense or other right that the Borrower may have at any time
         against any beneficiary or any transferee of such Letter of Credit (or
         any Person for whom any such beneficiary or any such transferee may be
         acting), the L/C Issuer or any other Person, whether in connection with
         this Agreement, the transactions contemplated hereby or by such Letter
         of Credit or any agreement or instrument relating thereto, or any
         unrelated transaction;

                           (iii) any draft, demand, certificate or other
         document presented under such 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; or any loss or delay
         in the transmission or otherwise of any document required in order to
         make a drawing under such Letter of Credit;

                           (iv) any payment by the L/C Issuer under such Letter
         of Credit against presentation of a draft or certificate that does not
         strictly comply with the terms of such Letter of Credit; or any payment
         made by the L/C Issuer under such Letter of Credit to any Person
         purporting to be a trustee in bankruptcy, debtor-in-possession,
         assignee for the benefit of creditors, liquidator, receiver or other
         representative of or successor to any beneficiary or any transferee of
         such Letter of Credit, including any arising in connection with any
         proceeding under the Bankruptcy Code or other similar law; or

                           (v) 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, the Borrower,

in each case, other than a defense based upon the gross negligence or willful
misconduct of the L/C Issuer or failure to perform the standard of care required
under applicable law.

         The Borrower shall promptly examine a copy of each Letter of Credit and
each amendment thereto that is delivered to it and, in the event of any claim of
noncompliance with the Borrower's instructions or other irregularity, the
Borrower will notify the L/C Issuer within 30 days of issuance or delivery. The
Borrower shall be conclusively deemed to have waived any such claim against the
L/C Issuer and its correspondents unless such notice is given as aforesaid.

                  (f) Role of L/C Issuer. Each Lender and the Borrower agree
that, in paying any drawing under a Letter of Credit, the L/C Issuer shall not
have any responsibility to obtain any document (other than any sight draft,
certificates and documents expressly required by the Letter of Credit) or to
ascertain or inquire as to the validity or accuracy of any such document or the

                                      -27-
<PAGE>

authority of the Person executing or delivering any such document. Neither the
L/C Issuer nor any of the respective correspondents, participants or assignees
of the L/C Issuer shall be liable to any Lender for (i) any action taken or
omitted in connection herewith at the request or with the approval of the
Lenders or the Majority Lenders, as applicable; (ii) any action taken or omitted
in the absence of gross negligence or willful misconduct; or (iii) the due
execution, effectiveness, validity or enforceability of any document or
instrument related to any Letter of Credit or Letter of Credit Application. The
Borrower hereby assumes all risks of the acts or omissions of any beneficiary or
transferee with respect to its use of any Letter of Credit; provided, however,
that this assumption is not intended to, and shall not, preclude the Borrower's
pursuing such rights and remedies as it may have against the beneficiary or
transferee at law or under any other agreement. Neither the L/C Issuer nor any
of the respective correspondents, participants or assignees of the L/C Issuer,
shall be liable or responsible for any of the matters described in clauses (i)
through (v) of Section 2.3(e); provided, however, that anything in such clauses
to the contrary notwithstanding, the Borrower may have a claim against the L/C
Issuer, and the L/C Issuer may be liable to the Borrower, to the extent, but
only to the extent, of any direct, as opposed to consequential or exemplary,
damages suffered by the Borrower which the Borrower proves were caused by the
L/C Issuer's willful misconduct or gross negligence or the L/C Issuer's willful
failure to pay under any Letter of Credit after the presentation to it by the
beneficiary of a sight draft and certificate(s) strictly complying with the
terms and conditions of a Letter of Credit or otherwise to fail to perform the
standard of care required under applicable law. In furtherance and not in
limitation of the foregoing, the L/C Issuer may accept documents that appear on
their face to be in order, without responsibility for further investigation,
regardless of any notice or information to the contrary, and the L/C Issuer
shall not be responsible for the validity or sufficiency of any instrument
transferring or assigning or purporting to transfer or assign a Letter of Credit
or the rights or benefits thereunder or proceeds thereof, in whole or in part,
which may prove to be invalid or ineffective for any reason.

                  (g) Cash Collateral. Upon written notice by the Agent, (i) if
any Event of Default has occurred and is continuing, or (ii) if, as of 60 days
prior to the Maturity Date, any Letter of Credit may for any reason remain
outstanding and partially or wholly undrawn, on the Business Day it receives
such notice from the Agent the Borrower shall Cash Collateralize the then
Outstanding Amount of all L/C Obligations (in an amount equal to such
Outstanding Amount determined as of the date of such L/C Borrowing) which such
amount shall be set forth in the notice. For purposes hereof, "Cash
Collateralize" means to pledge and deposit with or deliver to the Agent, for the
benefit of the L/C Issuer and the Lenders, as collateral for the L/C
Obligations, (i) cash, (ii) deposit account balances pursuant to documentation
in form and substance reasonably satisfactory to the Agent (which documents are
hereby consented to by the Lenders), or (iii) a standby letter of credit (issued
by a bank acceptable to Agent in its sole discretion) in an amount equal to the
Outstanding Amount of all L/C Obligations. Derivatives of such term have
corresponding meanings. The Borrower hereby grants to the Agent, for the benefit
of the L/C Issuer and the Lenders, a security interest in all such cash, deposit
accounts and all balances therein and rights under any standby letter of credit,
and all proceeds of the foregoing. Cash collateral shall be maintained in
blocked, non-interest bearing deposit accounts at Wells Fargo, but will be
invested overnight.

                  (h) Applicability of UCP and ISP98. Unless otherwise expressly
agreed by the L/C Issuer and the Borrower when a Letter of Credit is issued, in
L/C Issuer's discretion (i) the rules of the Uniform Customs and Practice for
Documentary Credits, as most recently published by the International Chamber of
Commerce (the "ICC") at the time of issuance (including the

                                      -28-
<PAGE>

ICC decision published by the Commission on Banking Technique and Practice on
April 6, 1998 regarding the European single currency (euro)) shall apply to each
commercial Letter of Credit, and (ii) the rules of the "International Standby
Practices 1998" published by the Institute of International Banking Law &
Practice (or such later version thereof as may be in effect at the time of
issuance) shall apply to each standby Letter of Credit.

                  (i) Letter of Credit Fees. The Borrower shall pay to the Agent
for the account of each Lender in accordance with its Commitment Percentage (i)
a one-time Letter of Credit fee for each commercial Letter of Credit equal to
0.25% times the face amount of such Letter of Credit (but in no event less than
$500 payable at issue) and (ii) per annum a Letter of Credit fee for each
standby Letter of Credit equal to the applicable Margin Percentage for LIBOR
Borrowings times the face amount of such Letter of Credit (but in no event less
than $500 payable at issue). Such letter of credit fees shall be computed on a
quarterly basis in arrears. Such letter of credit fees shall be due and payable
on each Quarterly Date, commencing with the first Quarterly Date to occur after
the issuance of such Letter of Credit, on the Letter of Credit Expiration Date
and thereafter on demand. If there is any change in the Margin Percentage during
any quarter, the actual daily amount of each Letter of Credit shall be computed
and multiplied by the Margin Percentage separately for each period during such
quarter that such Margin Percentage was in effect.

                  (j) Fronting Fee and Documentary and Processing Charges
Payable to L/C Issuer. The Borrower shall pay directly to the L/C Issuer for its
own account (i) a fronting fee for each standby Letter of Credit equal to 0.125%
times the face amount of such letter of credit (but in no event less than $500
payable at issue) due and payable on the issuance thereof and (ii) a fronting
fee with respect to each commercial Letter of Credit in the amounts and at the
times as determined in accordance with Wells Fargo's then current fee policy. In
addition, the Borrower shall pay directly to the L/C Issuer for its own account
the customary presentation, amendment, transfer and negotiation and other
processing fees, and other standard costs and charges, of the L/C Issuer
relating to letters of credit as from time to time determined in accordance with
Wells Fargo's then current fee policy. Such customary fees and standard costs
and charges are due and payable on demand and are nonrefundable.

                  (k) Fees Paid on Existing L/Cs. All fees paid to Wells Fargo
Bank, N.A. or any other parties before the date of this Agreement in respect of
any Existing L/Cs are solely for the account of those parties without any
accounting for them or sharing of them with the Agent or Lenders notwithstanding
any contrary provision in this Agreement.

                  (l) Conflict with Letter of Credit Application. In the event
of any conflict between the terms hereof and the terms of any Letter of Credit
Application, the terms hereof shall control.

         Section 2.4 Terminations or Reductions of Commitments.

                  (a) Mandatory. On the Maturity Date, all Commitments shall be
terminated in their entirety.

                  (b) Optional. Borrower shall have the right to terminate or
reduce the unused portion of the Commitments at any time or from time to time,
provided that (i) Borrower shall

                                      -29-
<PAGE>

give notice of each such termination or reduction to Agent as provided in
Section 4.3 hereof and (ii) each such partial reduction shall be in an integral
multiple of $500,000.

                  (c) No Reinstatement. No termination or reduction of the
Commitments may be reinstated without the written approval of Agent and the
Lenders.

         Section 2.5 Fees.

                  (a) Facility Fee. Borrower shall pay to Agent for the account
of each Lender in accordance with its Commitment Percentage, a facility fee
equal to the Facility Fee Percentage times the actual daily amount of the
Aggregate Commitments (or, of the Aggregate Commitments have terminated, on the
Outstanding Amount of all Revolving Loans, Swing Line Loans and L/C
Obligations), regardless of usage. Such facility fees shall be computed (on the
basis of the actual number of days elapsed in a year composed of 365 or 366
days, as the case may be) on each day. The facility fee shall be due and payable
in arrears on the Quarterly Dates prior to the Maturity Date and on the Maturity
Date (and, if applicable, thereafter on demand).

                  (b) Utilization Fee. Borrower shall pay to Agent for the
account of each Lender in accordance with its Commitment Percentage, a
utilization fee at a rate per annum equal to the Utilization Fee Percentage
times the Total Outstandings on each day that the Total Outstandings exceed 33
1/3% of the actual daily amount of the Aggregate Commitments. Such utilization
fees shall be computed (on the basis of the actual number of days elapsed in a
year composed of 365 or 366 days, as the case may be) on each day. The
utilization fee shall be due and payable in arrears on the Quarterly Dates prior
to the Maturity Date and on the Maturity Date.

                  (c) All past due fees payable under this Section shall bear
interest at the Past Due Rate.

         Section 2.6 Several Obligations. The failure of any Lender to make any
Loan to be made by it on the date specified therefor or to fund any
participation in Letters of Credit and Swing Line Loans on any date required
hereunder shall not relieve any other Lender of its obligation to make its Loan
or fund any such participation on such date, but neither Agent nor any Lender
shall be responsible or liable for the failure of any other Lender to make a
Loan or fund a participation to be made by such other Lender. Notwithstanding
anything contained herein to the contrary, (a) no Lender shall be required to
make or maintain Loans at any time outstanding if as a result the total
Obligations owed to such Lender shall exceed the lesser of (1) such Lender's
Commitment Percentage of all Obligations and (2) such Lender's Commitment
Percentage of the total Aggregate Commitments in effect at such time and (b) if
a Lender fails to make a Loan as and when required hereunder, then upon each
subsequent event which would otherwise result in funds being paid to the
defaulting Lender, the amount which would have been paid to the defaulting
Lender shall be divided among the non-defaulting Lenders ratably according to
their respective shares of the outstanding Commitment Percentages until the
Obligations of each Lender (including the defaulting Lender) are equal to such
Lender's Commitment Percentage of the total Obligations.

         Section 2.7 Notes. The Revolving Loans made by each Lender shall be
evidenced by a single promissory note of Borrower (each a "Revolving Note") in
substantially the form of Exhibit C hereto payable to the order of such Lender
in a principal amount equal to the Commitment of such Lender, and otherwise duly
completed. The Swing Line Loan shall be

                                      -30-
<PAGE>

evidenced by a single promissory note of the Borrower (the "Swing Line Note") in
substantially the form of Exhibit J hereto payable to the order of Swing Line
Lender in a principal amount equal to the Swing Line Sublimit, and otherwise
duly completed. The promissory notes described in this Section are each,
together with all renewals, extensions, modifications and replacements thereof
and substitutions therefor, collectively called the "Notes". Each Lender is
hereby authorized by Borrower to endorse on the schedule (or a continuation
thereof) that may be attached to each Note of such Lender, to the extent
applicable, the date, amount, type of and the applicable period of interest for
each Loan made by such Lender to Borrower hereunder, and the amount of each
payment or prepayment of principal of such Loan received by such Lender,
provided that any failure by such Lender to make any such endorsement shall not
affect the obligations of Borrower under such Note or hereunder in respect of
such Loan.

         Section 2.8 Use of Proceeds. The proceeds of the Credit Extensions
shall be used (i) to refinance certain existing Indebtedness of the Borrower,
(ii) for working capital and general corporate purposes (including acquisitions)
and (iii) to pay certain fees and expenses incurred in connection with the
transactions contemplated by this Agreement. Neither Agent nor any Lender shall
have any responsibility as to the use of any proceeds of the Credit Extensions.

         Section 2.9 Increase of Commitments.

                  (a) Provided no Default or Event of Default has occurred and
is continuing, upon notice to the Agent (which shall promptly notify the
Lenders), the Borrower may from time to time, request an increase in the
Aggregate Commitments to an aggregate amount of up to $300,000,000. At the time
of sending such notice, the Borrower (in consultation with the Agent) shall
specify the time period within which each Lender is requested to respond (which
shall in no event be less than 10 Business Days from the date of delivery of
such notice to the Lenders). Each Lender shall notify the Agent within such time
period whether or not it agrees to increase its Commitment and, if so, whether
by an amount equal to, greater than, or less than its Commitment Percentage of
such requested increase. Any Lender not responding within such time period shall
be deemed to have declined to increase its Commitment. The Agent shall notify
the Borrower and each Lender of the Lenders' responses to each request made
hereunder. To achieve the full amount of a requested increase, the Borrower may
also invite additional Eligible Assignees to become Lenders pursuant to a
joinder agreement in Proper Form.

                  (b) If the Aggregate Commitments are increased in accordance
with this Section, the Agent and the Borrower shall determine the effective date
(the "Increase Effective Date") and the final allocation of such increase. The
Agent shall promptly notify the Borrower and the Lenders of the final allocation
of such increase and the Increase Effective Date. As a condition precedent to
such increase, the Borrower shall deliver to the Agent a certificate of the
Borrower dated as of the Increase Effective Date (in sufficient copies for each
Lender) signed by a Responsible Officer (i) certifying and attaching the
resolutions adopted by the Borrower approving or consenting to such increase,
and (ii) certifying that, before and after giving effect to such increase, (A)
the representations and warranties contained in Section 6 hereof and the other
Loan Documents are true and correct on and as of the Increase Effective Date,
except to the extent that such representations and warranties specifically refer
to an earlier date, in which case they are true and correct as of such earlier
date, and except that for purposes of this Section 2.9, the representations and
warranties contained in Section 6.2 shall be deemed to refer to the most recent
statements furnished pursuant to subsections (a) and (b) of Section 7.2, and (B)
no Default or Event of Default exists. The Borrower shall prepay any Revolving
Loans outstanding on the

                                      -31-
<PAGE>

Increase Effective Date (and pay any additional amounts required pursuant to
Section 3.3(c)(iv)) to the extent necessary to keep the outstanding Revolving
Loans ratable with any revised Commitment Percentages arising from any
nonratable increase in the Commitments under this Section.

                  (c) This Section shall supersede any provisions in Sections
4.5, 11.5 or 11.6 to the contrary.

Section 2.10 Non-Application of Chapter 346 of Texas Finance Code. Borrower,
Agent and the Lenders agree pursuant to Chapter 346 ("Chapter 346") of the Texas
Finance Code, that Chapter 346 (which relates to open-end line of credit
revolving loan accounts) shall not apply to this Agreement, the Notes or any
Obligation and that neither the Notes nor any Obligation shall be governed by
Chapter 346 or subject to its provisions in any manner whatsoever.

SECTION 3. BORROWINGS, PAYMENTS, PREPAYMENTS AND INTEREST OPTIONS.

         Section 3.1 Borrowings. Borrower shall give Agent notice of each
borrowing to be made hereunder as provided in Section 4.3 hereof and Agent shall
promptly notify each Lender of such request. Not later than 12:00 noon central
time on the date specified for each such borrowing hereunder, each Lender shall
make available the amount of the Loan, if any, to be made by it on such date to
Agent at its Principal Office, in immediately available funds, for the account
of Borrower. Such amounts received by Agent will be held in an account
maintained by Borrower with Agent. The amounts so received by Agent shall,
subject to the terms and conditions of this Agreement, be made available to
Borrower by wiring or otherwise transferring, in immediately available funds,
such amount to an account designated by Borrower and approved by Agent.

         Section 3.2 Payments; Prepayments.

                  (a) Optional Prepayments on Revolving Loans. Except as
provided in Section 3.3 hereof, Borrower shall have the right to prepay, on any
Business Day, in whole or in part, without the payment of any premium, penalty
or fee (other than Funding Losses), any Revolving Loans at any time or from time
to time, provided that Borrower shall give Agent notice of each such prepayment
as provided in Section 4.3 hereof. Each optional prepayment on a Revolving Loan
shall be in an amount equal to a minimum of $1,000,000 plus integral multiples
of $500,000.

                  (b) Optional Prepayments on Swing Line Loans. Borrower shall
have the right to prepay, on any Business Day, in whole or in part, without the
payment of any premium, penalty or fee, any Swing Line Loans at any time or from
time to time, provided that Borrower shall give Agent notice of each such
prepayment as provided in Section 4.3 hereof. Each optional prepayment on a
Swing Line Loan shall be in an amount equal to a minimum of $500,000.

                  (c) Mandatory Prepayments. If for any reason the Total
Outstandings at any time exceed the Aggregate Commitments then in effect, the
Borrower shall immediately prepay Loans and/or Cash Collateralize the L/C
Obligations in an aggregate amount equal to such excess; provided, however, that
the Borrower shall not be required to Cash Collateralize the L/C Obligations
pursuant to this Section 3.2(c) unless after the prepayment in full of the
Revolving

                                      -32-
<PAGE>

Loans and the Swing Line Loans the Total Outstandings exceed the Aggregate
Commitments then in effect.

                  (d) Interest Payments. Accrued and unpaid interest on the
unpaid principal balance of the Loans shall be due and payable on the Interest
Payment Dates and on the date of any prepayment of the Loans.

                  (e) Interest on Past Due Payments. Subject to Section 11.7
hereof, Borrower will pay to Agent for the account of each Lender interest at
the applicable Past Due Rate on any amount payable by Borrower hereunder to or
for the account of such Lender (but, if such amount is interest, only to the
extent legally allowed), which shall not be paid in full within five (5) days
after the date due (whether at stated maturity, by acceleration or otherwise),
for the period commencing on the expiration of such five (5) day period until
the same is paid in full.

         Section 3.3 Interest Options.

                  (a) Options Available. The outstanding principal balance of
the Notes shall bear interest at the Base Rate; provided, that (1) subject to
Section 3.2(e), all past due amounts, both principal and accrued and unpaid
interest, shall bear interest at the Past Due Rate, and (2) subject to the
provisions hereof, Borrower shall have the option of having all or any portion
of the principal balances of the Revolving Notes from time to time outstanding
bear interest at a Eurodollar Rate. The records of Agent and each of the Lenders
with respect to Interest Options, Interest Periods and the amounts of Loans to
which they are applicable shall be prima facie evidence of the correctness
thereof. Interest on the Revolving Loans shall be calculated at the Base Rate
except where it is expressly provided pursuant to this Agreement that a
Eurodollar Rate is to apply. Interest on the amount of each advance against the
Notes shall be computed on the amount of that advance and from the date it is
made to but excluding the date of repayment thereof. Notwithstanding anything in
this Agreement to the contrary, for the full term of the Notes the interest rate
produced by the aggregate of all sums paid or agreed to be paid to the holders
of the Notes for the use, forbearance or detention of the debt evidenced thereby
(including all interest on the Notes at the Stated Rate plus the Additional
Interest) shall not exceed the Ceiling Rate.

                  (b) Designation and Conversion. Borrower shall have the right
to designate or convert its Interest Options in accordance with the provisions
hereof. Provided no Event of Default has occurred and is continuing and subject
to the last sentence of Section 3.3(a) and the provisions of Section 3.3(c),
Borrower may elect to have a Eurodollar Rate apply or continue to apply to all
or any portion of the principal balance of the Revolving Notes. Each change in
Interest Options shall be a conversion of the rate of interest applicable to the
specified portion of the Revolving Loans, but such conversion shall not change
the respective outstanding principal balances of the Revolving Notes. The
Interest Options shall be designated or converted in the manner provided below:

                           (i) Borrower shall give Agent telephonic notice,
         promptly confirmed by a Rate Designation Notice (and Agent shall
         promptly inform each Lender thereof). Each such telephonic and written
         notice shall specify the amount of the Revolving Loan which is the
         subject of the designation, if any; the amount of borrowings into which
         such borrowings are to be converted or for which an Interest Option is
         designated; the proposed date for the designation or conversion and the
         Interest Period or Periods, if any,

                                      -33-
<PAGE>

         selected by Borrower. Such telephonic notice shall be irrevocable and
         shall be given to Agent no later than the applicable Rate Designation
         Date.

                           (ii) No more than ten (10) LIBOR Borrowings shall be
         in effect at any time.

                           (iii) Each advance, designation or conversion of a
         LIBOR Borrowing shall occur on a LIBOR Business Day.

                           (iv) Except as provided in Section 3.3(c) hereof, no
         LIBOR Borrowing may be converted to a Base Rate Borrowing or another
         LIBOR Borrowing on any day other than the last day of the applicable
         Interest Period.

                           (v) Each request for a LIBOR Borrowing shall be in
         the amount equal to $5,000,000 or an integral multiple of $1,000,000 in
         excess thereof.

                           (vi) Subject to Section 3.3(c)(i), each designation
         of an Interest Option with respect to the Revolving Notes shall apply
         to all of the Revolving Notes ratably in accordance with their
         respective outstanding principal balances. If any Lender assigns an
         interest in its Revolving Note when any LIBOR Borrowing is outstanding
         with respect thereto, then such assignee shall have its ratable
         interest in such LIBOR Borrowing.

                  (c) Special Provisions Applicable to LIBOR Borrowings.

                           (i) Options Unlawful. If the adoption of any
         applicable Legal Requirement after the Effective Date or any change
         after the Effective Date in any applicable Legal Requirement or in the
         interpretation or administration thereof by any Governmental Authority
         or compliance by any Lender with any request or directive (whether or
         not having the force of law) issued after the Effective Date by any
         central bank or other Governmental Authority shall at any time make it
         unlawful or impossible for any Lender to permit the establishment of or
         to maintain any LIBOR Borrowing, the commitment of such Lender to
         establish such LIBOR Borrowing shall forthwith be canceled and Borrower
         shall on the last day the Interest Period relating to any outstanding
         LIBOR Borrowing (or within such earlier period as may be required by
         applicable law) (1) convert the LIBOR Borrowing of such Lender to a
         Base Rate Borrowing; (2) pay all accrued and unpaid interest to date on
         the amount so converted; and (3) pay any amounts required to compensate
         each Lender for any additional cost or expense which any Lender may
         incur as a result of such adoption of or change in such Legal
         Requirement or in the interpretation or administration thereof and any
         Funding Loss which any Lender may incur as a result of such conversion.
         If, when Agent so notifies Borrower, Borrower has given a Rate
         Designation Notice specifying a LIBOR Borrowing but the selected
         Interest Period has not yet begun, as to the applicable Lender such
         Rate Designation Notice shall be deemed to be of no force and effect,
         as if never made, and the balance of the Revolving Loans made by such
         Lender specified in such Rate Designation Notice shall bear interest at
         the Base Rate until a different available Interest Option shall be

                           (ii) Increased Cost of Borrowings. Subject to Section
         11.15, if the adoption after the Effective Date of any applicable Legal
         Requirement or any change after the Effective Date in any applicable
         Legal Requirement or in the interpretation or

         administration thereof by any Governmental Authority or compliance by
         any Lender with any request or directive (whether or not having the
         force of law) issued after the Effective Date by any central bank or
         Governmental Authority shall at any time as a result of any portion of
         the principal balances of the Revolving Notes being maintained on the
         basis of a Eurodollar Rate:

                                    (1) subject any Lender to any Taxes, or any
                           deduction or withholding for any Taxes, on or from
                           any payment due under any LIBOR Borrowing or other
                           amount due hereunder, other than income and franchise
                           taxes of the United States or its political
                           subdivisions or such other jurisdiction in which the
                           applicable Lender has any office or applicable
                           lending office; or

                                    (2) change the basis of taxation of payments
                           due from Borrower to any Lender under any LIBOR
                           Borrowing (otherwise than by a change in the rate of
                           taxation of the gross revenues or overall net income
                           of such Lender); or

                                    (3) impose, modify, increase or deem
                           applicable any reserve requirement (excluding that
                           portion of any reserve requirement included in the
                           calculation of the applicable Eurodollar Rate),
                           special deposit requirement or similar requirement
                           (including, but not limited to, state law
                           requirements) against assets of any Lender, or
                           against deposits with any Lender, or against loans
                           made by any Lender, or against any other funds,
                           obligations or other Property owned or held by any
                           Lender; or

                                    (4) impose on any Lender any other condition
                           regarding any LIBOR Borrowing;

                           and the result of any of the foregoing is to increase
                           the cost to any Lender of agreeing to make or of
                           making, renewing or maintaining such LIBOR Borrowing,
                           or reduce the amount of principal or interest
                           received by any Lender, then, within 15 Business Days
                           after demand by Agent (accompanied by a statement
                           setting forth in reasonable detail the applicable
                           Lender's basis therefor), Borrower shall pay to Agent
                           additional amounts which shall compensate each Lender
                           for such increased cost or reduced amount. The
                           determination by any Lender of the amount of any such
                           increased cost, increased reserve requirement or
                           reduced amount shall be prima facie evidence of the
                           correctness thereof. Borrower shall have the right,
                           if it receives from Agent any notice referred to in
                           this paragraph, upon three Business Days' notice to
                           Agent (which shall notify each affected Lender),
                           either (i) to repay in full (but not in part) any
                           borrowing with respect to which such notice was
                           given, together with any accrued interest thereon, or
                           (ii) to convert the LIBOR Borrowing which is the
                           subject of the notice to a Base Rate Borrowing;
                           provided, that any such repayment or conversion shall
                           be accompanied by payment of (x) the amount required
                           to compensate each Lender for the increased cost or
                           reduced amount referred to in the preceding
                           paragraph; (y) all accrued and unpaid interest to
                           date on the amount so repaid or converted, and (z)
                           any

                                      -35-
<PAGE>

                           Funding Loss which any Lender may incur as a result
                           of such repayment or conversion. Each Lender will
                           notify Borrower through Agent of any event occurring
                           after the date of this Agreement which will entitle
                           such Lender to compensation pursuant to this Section
                           as promptly as practicable after it obtains knowledge
                           thereof and determines to request such compensation,
                           and (if so requested by Borrower through Agent) will
                           designate a different lending office of such Lender
                           for the applicable LIBOR Borrowing or will take such
                           other action as Borrower may reasonably request if
                           such designation or action is consistent with the
                           internal policy of such Lender and legal and
                           regulatory restrictions, will avoid the need for, or
                           reduce the amount of, such compensation and will not,
                           in the sole opinion of such Lender, be
                           disadvantageous to such Lender (provided that such
                           Lender shall have no obligation so to designate a
                           different lending office which is located in the
                           United States of America).

                           (iii) Inadequacy of Pricing and Rate Determination.
         If, for any reason with respect to any Interest Period, Agent (or, in
         the case of clause 3 below, the applicable Lender) shall have
         reasonably determined that:

                                    (1) Agent is unable through its customary
                           general practices to determine any applicable
                           Eurodollar Rate, or

                                    (2) by reason of circumstances affecting the
                           applicable market, generally, Agent is not being
                           offered deposits in United States dollars in such
                           market, for the applicable Interest Period and in an
                           amount equal to the amount of any applicable LIBOR
                           Borrowing requested by Borrower, or

                                    (3) any applicable Eurodollar Rate will not
                           adequately and fairly reflect the cost to any Lender
                           of making and maintaining such LIBOR Borrowing
                           hereunder for any proposed Interest Period,

                           then Agent shall give Borrower notice thereof and
                           thereupon, (A) any Rate Designation Notice previously
                           given by Borrower designating the applicable LIBOR
                           Borrowing which has not commenced as of the date of
                           such notice from Agent shall be deemed for all
                           purposes hereof to be of no force and effect, as if
                           never given, and (B) until Agent shall notify
                           Borrower that the circumstances giving rise to such
                           notice from Agent no longer exist, each Rate
                           Designation Notice requesting the applicable
                           Eurodollar Rate shall be deemed a request for a Base
                           Rate Borrowing, and any applicable LIBOR Borrowing
                           then outstanding shall be converted, without any
                           notice to or from Borrower, upon the termination of
                           the Interest Period then in effect with respect to
                           it, to a Base Rate Borrowing.

                           (iv) Funding Losses. Borrower shall indemnify each
         Lender against and hold each Lender harmless from any Funding Loss.
         Subject to Section 11.15, this indemnity shall survive the payment of
         the Revolving Notes. Within 15 Business Days after demand by Agent
         (accompanied by a certificate of such Lender setting forth in
         reasonable detail the amount and calculation of the amount claimed as
         to any Funding

                                      -36-
<PAGE>

         Losses, which shall be prima facie evidence of the correctness
         thereof), Borrower shall pay to Agent, for the account of such Lender,
         the amount of such Funding Losses.

                  (d) Funding Offices; Adjustments Automatic; Calculation Year.
Any Lender may, if it so elects, fulfill its obligation as to any LIBOR
Borrowing by causing a branch or affiliate of such Lender to make such Revolving
Loan and may transfer and carry such Revolving Loan at, to or for the account of
any branch office or affiliate of such Lender; provided, that in such event for
the purposes of this Agreement such Revolving Loan shall be deemed to have been
made by such Lender and the obligation of Borrower to repay such Revolving Loan
shall nevertheless be to such Lender and shall be deemed held by it for the
account of such branch or affiliate. Without notice to Borrower or any other
Person, each rate required to be calculated or determined under this Agreement
shall automatically fluctuate upward and downward in accordance with the
provisions of this Agreement. Interest at the Prime Rate and at the Base Rate
shall be computed on the basis of the actual number of days elapsed in a year
consisting of 365 or 366 days, as the case may be. All other interest required
to be calculated or determined under this Agreement shall be computed on the
basis of the actual number of days elapsed in a year consisting of 360 days,
unless the Ceiling Rate would thereby be exceeded, in which event, to the extent
necessary to avoid exceeding the Ceiling Rate, the applicable interest shall be
computed on the basis of the actual number of days elapsed in the applicable
calendar year in which accrued.

                  (e) Funding Sources. Notwithstanding any provision of this
Agreement to the contrary, each Lender shall be entitled to fund and maintain
its funding of all or any part of the Revolving Loans in any manner it sees fit,
it being understood, however, that for the purposes of this Agreement all
determinations hereunder shall be made as if each Lender had actually funded and
maintained each LIBOR Borrowing during each Interest Period through the purchase
of deposits having a maturity corresponding to such Interest Period and bearing
an interest rate equal to the Eurodollar Rate for such Interest Period.

SECTION 4. PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS, ETC.

         Section 4.1 Payments.

                  (a) The Borrower shall repay to the Lenders on the Maturity
Date the aggregate amount of Revolving Loans outstanding on such date.

                  (b) The Borrower shall repay each Swing Line Loan on the
earlier to occur of (i) the date 10 days after such Swing Line Loan is made and
(ii) the Maturity Date.

                  (c) Except to the extent otherwise provided herein, all
payments of principal, interest and other amounts to be made by Borrower
hereunder, under the Notes and under the other Loan Documents shall be made in
Dollars, in immediately available funds, to Agent at the Principal Office (or in
the case of a successor Agent, at the principal office of such successor Agent
in the United States), not later than 11:00 a.m. central time on the date on
which such payment shall become due (each such payment made after such time on
such due date to be deemed to have been made on the next succeeding Business
Day).

                  (d) Borrower shall, at the time of making each payment
hereunder, under any Note or under any other Loan Document, specify to Agent the
Loans or other amounts payable by Borrower hereunder or thereunder to which such
payment is to be applied. Each payment

                                      -37-
<PAGE>

received by Agent hereunder, under any Note or under any other Loan Document for
the account of a Lender shall be paid promptly to such Lender, in immediately
available funds. If Agent fails to send to any Lender the applicable amount by
the close of business on the date any such payment is received by Agent if such
payment is received prior to 11:00 a.m. central time (or on the next succeeding
Business Day with respect to payments which are received after 11:00 a.m.
central time), Agent shall pay to the applicable Lender interest on such amount
from such date at the Federal Funds Rate. Borrower, the Lenders and Agent
acknowledge and agree that this provision and each other provision of this
Agreement or any of the other Loan Documents relating to the application of
amounts in payment of the Obligations shall be subject to the provisions of
Section 4.2(f) regarding pro rata application of amounts after an Event of
Default shall have occurred and be continuing.

                  (e) If the due date of any payment hereunder or under any Note
falls on a day which is not a Business Day, the due date for such payments
(except as otherwise provided in clause (2) of the definition of "Interest
Period") shall be extended to the next succeeding Business Day and interest
shall be payable for any principal so extended for the period of such extension.

                  (f) All payments by Borrower hereunder or under any other Loan
Document shall be made free and clear of and without deduction for or on account
of any present or future income, stamp, or other taxes, fees, duties,
withholding or other charges of any nature whatsoever imposed by any taxing
authority excluding in the case of Agent and each Lender taxes imposed on or
measured by its net income or franchise taxes imposed by the jurisdiction in
which it is organized or through which it acts for purposes of this Agreement
(such non-excluded items being hereinafter referred to as "Taxes"). If as a
result of any change in law (or the interpretation thereof) after the date that
Agent or the applicable Lender became a party to this Agreement, any withholding
or deduction from any payment to be made to, or for the account of, such Person
by Borrower hereunder or under any other Loan Document is required in respect of
any Taxes pursuant to any applicable law, rule, or regulation, then Borrower
will (i) pay to the relevant authority the full amount required to be so
withheld or deducted; (ii) to the extent available, promptly forward to Agent an
official receipt or other documentation reasonably satisfactory to Agent
evidencing such payment to such authority; and (iii) pay to Agent, for the
account of each affected Person, such additional amount or amounts as are
necessary to ensure that the net amount actually received by such Lender will
equal the full amount such Person would have received had no such withholding or
deduction been required. Each such Person shall determine such additional amount
or amounts payable to it (which determination shall be prima facie evidence of
the correctness thereof). If Agent or any Lender becomes aware that any such
withholding or deduction from any payment to be made by Borrower hereunder or
under any other Loan Document is required, then such Person shall promptly
notify Agent and Borrower thereof stating the reasons therefor and the
additional amount required to be paid under this Section. Each Lender shall
execute and deliver to Agent and Borrower such forms as it may be required to
execute and deliver pursuant to Section 11.13 hereof. To the extent that any
such withholding or deduction results from the failure of a Lender to provide a
form required by Section 11.13 hereof (unless such failure is due to some
prohibition under applicable Legal Requirements), Borrower shall have no
obligation to pay the additional amount required by clause (iii) above. Anything
in this Section notwithstanding, if any Lender elects to require payment by
Borrower of any material amount under this Section, Borrower may, within 60 days
after the date of receiving notice thereof and so long as no Default shall have
occurred and be continuing, elect to terminate such Lender as a party to this
Agreement; provided that,

                                      -38-
<PAGE>

concurrently with such termination Borrower shall (i) if Agent and each of the
other Lenders shall consent, pay that Lender all principal, interest and fees
and other amounts owed to such Lender through such date of termination or (ii)
have arranged for another financial institution approved by Agent (such approval
not to be unreasonably withheld or delayed) as of such date, to become a
substitute Lender for all purposes under this Agreement in the manner provided
in Section 11.6; provided further that, prior to substitution for any Lender,
Borrower shall have given written notice to Agent of such intention and the
Lenders shall have the option, but no obligation, for a period of 60 days after
receipt of such notice, to increase their Commitments in order to replace the
affected Lender in lieu of such substitution.

         Section 4.2 Pro Rata Treatment. Except to the extent otherwise provided
herein: (a) each revolving borrowing from the Lenders under Section 2.1 hereof
shall be made ratably from the Lenders in accordance with their respective
Commitments; (b) each Lender's participations in L/C Obligations or Swing Line
Loans shall be determined, pro rata, according to the Lender's respective
Commitments; (c) each payment of facility and utilization fees shall be made for
the account of the Lenders, and each termination or reduction of the Commitments
of the Lenders under Section 2.4 hereof shall be applied, pro rata, according to
the Lenders' respective Commitments, and (d) each payment by Borrower of
principal of or interest on the Loans shall be made to Agent for the account of
the Lenders pro rata in accordance with the respective unpaid principal amounts
of such Loans held by the Lenders.

         Section 4.3 Certain Actions, Notices, Etc. Notices to Agent of any
termination or reduction of Commitments and of borrowings and optional
prepayments of Loans shall be irrevocable and shall be effective only if
received by Agent not later than 12:00 noon central time on the number of
Business Days prior to the date of the relevant termination, reduction,
borrowing and/or prepayment specified below:

Each such notice of termination or reduction shall specify the amount of the
applicable Commitment to be terminated or reduced. Each such notice of borrowing
or prepayment shall specify the amount of the Loans to be borrowed or prepaid
and the date of borrowing or prepayment (which shall be a Business Day). Agent
shall promptly notify the affected Lenders of the contents of each such notice.

         Section 4.4 Non-Receipt of Funds by Agent. Unless Agent shall have been
notified by a Lender or Borrower (the "Payor") prior to the date on which such
Lender is to make

                                      -39-
<PAGE>

payment to Agent of the proceeds of a Loan to be made by it hereunder or
Borrower is to make a payment to Agent for the account of one or more of the
Lenders, as the case may be (such payment being herein called the "Required
Payment"), which notice shall be effective upon receipt, that the Payor does not
intend to make the Required Payment to Agent, Agent may assume that the Required
Payment has been made and may, in reliance upon such assumption (but shall not
be required to), make the amount thereof available to the intended recipient on
such date and, if the Payor has not in fact made the Required Payment to Agent,
the recipient of such payment shall, on demand, pay to Agent the amount made
available by Agent, together with interest thereon in respect of the period
commencing on the date such amount was so made available by Agent until the date
Agent recovers such amount at a rate per annum equal to the Federal Funds Rate
for such period.

         Section 4.5 Sharing of Payments, Etc. If a Lender shall obtain payment
of any principal of or interest on account of any Loan made by it under this
Agreement, or the participations in L/C Obligations or Swing Line Loans held by
it, or on any other Obligation then due to such Lender hereunder, through the
exercise of any right of set-off (including, without limitation, any right of
setoff or Lien granted under Section 9.2 hereof), banker's lien, counterclaim or
similar right or otherwise, it shall promptly purchase from the other Lenders
participations in the Revolving Loans made, and/or such subparticipations in the
participations in the L/C Obligations, Swing Line Loans or other Obligations
held, by the other Lenders in such amounts, and make such other adjustments from
time to time as shall be equitable to the end that all the Lenders shall share
the benefit of such payment (net of any expenses which may be incurred by such
Lender in obtaining or preserving such benefit) pro rata in accordance with the
unpaid Obligations then due to each of them; provided, however, that if all or
any portion of such excess payment is thereafter recovered from such purchasing
Lender, such purchase from each Lender shall be rescinded and such Lender shall
repay to the purchasing Lender the purchase price to the extent of such recovery
together with an amount equal to such Lender's ratable share (according to the
proportion of (i) the amount of such Lender's required repayment to (ii) the
total amount so recovered from the purchasing Lender) of any interest or other
amount paid or payable by the purchasing Lender in respect of the total amount
so recovered. To such end all the Lenders shall make appropriate adjustments
among themselves (by the resale of participations sold or otherwise) if such
payment is rescinded or must otherwise be restored. Borrower agrees, to the
fullest extent it may effectively do so under applicable law, that any Lender so
purchasing a participation in the Loans made, and/or such subparticipations in
the participations in the L/C Obligations, Swing Line Loans or other Obligations
held, by other Lenders may exercise all rights of set-off, bankers' lien,
counterclaim or similar rights with respect to such participation as fully as if
such Lender were a direct holder of Loans, participations in L/C Obligations or
Swing Line Loans or other Obligations in the amount of such participation.
Nothing contained herein shall require any Lender to exercise any such right or
shall affect the right of any Lender to exercise, and retain the benefits of
exercising, any such right with respect to any other indebtedness or obligation
of Borrower.

SECTION 6. REPRESENTATIONS AND WARRANTIES.

         To induce Agent and the Lenders to enter into this Agreement and to
make the Credit Extensions, Borrower represents and warrants (such
representations and warranties to survive any investigation and the making of
the Credit Extensions) to the Lenders and Agent as follows:

         Section 6.1 Organization. Borrower and each of its Restricted
Subsidiaries (a) is duly organized, validly existing and in good standing under
the laws of the jurisdiction of its organization; (b) has all necessary power
and authority to conduct its business as presently conducted, and (c) is duly
qualified to do business and in good standing in the jurisdiction of its
organization and in all jurisdictions in which the failure to so qualify could

         Section 6.2 Financial Statements. Borrower has furnished to Agent (i)
audited financial statements (including a balance sheet) as to Borrower which
fairly present in all material respects, in accordance with GAAP, the
consolidated financial condition and the results of operations of Borrower and
its Subsidiaries as of the end of the fiscal year ended December 31, 2002, (ii)
unaudited financial statements (including a balance sheet) as to Borrower which
fairly present in all material respects, in accordance with GAAP (subject to
year-end adjustments and the absence of notes), the consolidated financial
condition and the results of operations of Borrower and its Subsidiaries as of
the end of the fiscal quarter ended September 30, 2003 and (iii) financial
projections for the fiscal year ending December 31, 2004, including a pro forma
balance sheet and statements of projected income and cash flow, all after giving
effect to the contemplated acquisitions described therein. No events, conditions
or circumstances have occurred from the date that the actual financial
statements were delivered to Agent through the Effective Date which would cause
said financial statements to be misleading in any material respect, provided
that, with respect to projected financial information, the Borrower represents
only that such information was prepared in good faith based on assumptions
believed to be reasonable at the time, it being recognized by the Lenders that
such projections as to future events are not to be viewed as facts and that
actual results during the period or periods covered by any such projections may
differ from the projected results.. There are no material instruments or
liabilities which should be reflected in such financial statements provided to
Agent which are not so reflected that are necessary in order for such financial
statement

Material Adverse Effect.

         Section 6.3 Enforceable Obligations; Authorization. The Loan Documents
are legal, valid and binding obligations of Borrower, enforceable in accordance
with their respective terms, except as may be limited by bankruptcy, insolvency
and other similar laws and judicial decisions affecting creditors' rights
generally and by general equitable principles. The execution, delivery and
performance of the Loan Documents by Borrower (a) have all been duly authorized
by all necessary action; (b) are within the corporate power and authority of
Borrower; (c) do not and will not contravene or violate any Legal Requirement
applicable to Borrower or the Organizational Documents of Borrower, the
contravention or violation of which could reasonably be expected to have a
Material Adverse Effect; (d) do not and will not result in the breach of, or
constitute a default under, any material agreement or instrument by which
Borrower or any of its Property may be bound, and (e) do not and will not result
in the creation of any Lien upon any Property of Borrower, except in favor of
Agent or as expressly contemplated herein or therein. All necessary permits,
registrations and consents for such making and performance have been obtained.

         Section 6.4 Other Debt. Neither Borrower nor any its Restricted

proceeding, to the knowledge of any executive officer of Borrower, pending or

filed all tax returns required to have been filed and paid all taxes shown
thereon to be due, except those for which extensions have been obtained and
those which are being contested in good faith or where the failure to make
required filings or pay required taxes could not reasonably be expected to have
a Material Adverse Effect.

         Section 6.7 Regulations U and X. None of the proceeds of any Loan will
be used for the purpose of purchasing or carrying directly or indirectly any
margin stock or for any other purpose would constitute this transaction a
"purpose credit" within the meaning of Regulations U and X of the Board of
Governors of the Federal Reserve System, as any of them may be amended from time
to time.

         Section 6.8 Subsidiaries. As of the Effective Date, Borrower has no

Controlled Group to the PBGC or a Plan (other than to make contributions in the
ordinary course) could reasonably be expected to have a Material Adverse Effect.
There have not been any nor are there now existing any events or conditions that
would cause the Lien provided under Section 4068 of ERISA to attach to any
Property of Borrower or any member of the Controlled Group. Unfunded Liabilities
as of the date hereof are not reasonably expected to result in a Material
Adverse Effect. No "prohibited transaction" has occurred with respect to any

reasonably be expected to have a Material Adverse Effect. Borrower and each of
its Restricted Subsidiaries and their Properties, business and operations have
been and are, to the best knowledge of their respective executive officers, in
compliance with all applicable Requirements of Environmental Law and
Environmental Permits the failure to comply with which could reasonably be
expected to have a Material Adverse Effect. Borrower and each of its Restricted

notice of any violation or alleged

                                      -44-

of any event or condition with respect to currently enacted Requirements of
Environmental Laws presently scheduled to become effective in the future with
respect to any of the Properties of Borrower or any of its Restricted

Restricted Subsidiary in its business plan and projections of financial
performance.

1.6011-4). In the event the Borrower determines to take any action inconsistent
with such intention, it will promptly notify the Agent thereof. If the Borrower
so notifies the Agent, the Borrower acknowledges that one or more of the Lenders
may treat its Revolving Loans and/or its interest in Swing Line Loans and/or
Letters of Credit as part of a transaction that is subject to Treasury
Regulation Section 301.6112-1, and such Lender or Lenders, as applicable, will
maintain the lists and other records required by such Treasury Regulation.

Authority, central bank or comparable agency has or would have the effect of
reducing the rate of return on the capital of such Lender or any corporation
controlling such Lender as a consequence of its obligations hereunder, under the
Notes or other Obligations held by it to a level below that which such Lender or
such corporation could have achieved but for such adoption, change or compliance

therein or in connection herewith or therewith, INCLUDING, WITHOUT LIMITATION,
PURSUANT TO ITS OWN NEGLIGENCE, except for its own gross negligence or willful
misconduct; (e) shall not be bound by or obliged to recognize any agreement
among or between Borrower and any Lender to which Agent is not a party,
regardless of whether Agent has knowledge of the existence of any such agreement
or the terms and provisions thereof; (f) shall not be charged with notice or
knowledge of any fact or information not herein set out or provided to Agent in
accordance with the terms of this Agreement or any other Loan Document; (g)
shall not be responsible for any delay, error, omission or default of any mail,
telegraph, cable or wireless agency or operator, and (h) shall not be
responsible for the acts or edicts of any Governmental Authority. Agent may
employ agents and attorneys-in-fact and shall not be responsible for the
negligence or misconduct of any such agents or attorneys-in-fact selected by it
with reasonable care.

                  (b) Each L/C Issuer shall act on behalf of the Lenders with
respect to any Letters of Credit issued by it and the documents associated
therewith until such time (and except for so long) as the Agent may agree at the
request of the Majority Lenders to act for such L/C Issuer shall have all the
benefits and immunities (i) provided to Agent in this Section 10 with respect to
any acts or omissions suffered by each such L/C Issuer in connection with
Letters of Credit issued by it or proposed to be issued by it and the
application and agreements for letters of credit pertaining to the Letters of
Credit as fully as if the term "Agent" as used in this Section 10 included each
L/C Issuer with respect to such acts or omissions, and (ii) as additionally
provided herein with respect to each L/C Issuer.

         Section 10.2 Reliance. Agent shall be entitled to rely upon any
certification, notice or other communication (including any thereof by
telephone, telegram or cable) believed by it to be genuine and correct and to
have been signed or sent by or on behalf of the proper Person or Persons, and
upon advice and statements of legal counsel (which may be counsel for Borrower),
independent accountants and other experts selected by Agent. Agent shall not be
required in any way to determine the identity or authority of any Person
delivering or executing the same. As to any matters not expressly provided for
by this Agreement or any other Loan Document, Agent shall in all cases be fully
protected in acting, or in refraining from acting, hereunder and thereunder in
accordance with instructions of the Majority Lenders, and any action taken or
failure to act pursuant thereto shall be binding on all of the Lenders. If any
order, writ, judgment or decree shall be made or entered by any court affecting
the rights, duties and obligations of Agent under this Agreement or any other
Loan Document, then and in any of such events Agent is authorized, in its sole
discretion, to rely upon and comply with such order, writ, judgment or decree
which it is advised by legal counsel of its own choosing is binding upon it
under the terms of this Agreement, the relevant Loan Document or otherwise; and
if Agent complies with any such order, writ, judgment or decree, then it shall
not be liable to any Lender or to any other Person by reason of such compliance
even though such order, writ, judgment or decree may be subsequently reversed,
modified, annulled, set aside or vacated.

         Section 10.3 Defaults. Agent shall not be deemed to have knowledge of
the occurrence of a Default or Event of Default (other than the non-payment of
principal of or interest on Loans) unless Agent has received notice from a
Lender or Borrower specifying such Default or Event of Default and stating that
such notice is a "Notice of Default." In the event that Agent receives such a
Notice of Default, Agent shall give prompt notice thereof to the Lenders (and
shall give each Lender prompt notice of each such non-payment). Agent shall
(subject to Section 10.7 hereof) take such action with respect to such Notice of
Default as shall

                                      -62-
<PAGE>

be directed by the Majority Lenders and within its rights under the Loan
Documents and at law or in equity, provided that, unless and until Agent shall
have received such directions, Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, permitted hereby with respect
to such Notice of Default as it shall deem advisable in the best interests of
the Lenders and within its rights under the Loan Documents, at law or in equity.

         Section 10.4 Material Written Notices. In the event that Agent receives
any written notice of a Material nature from Borrower under the Loan Documents,
Agent shall promptly inform each of the Lenders thereof.

         Section 10.5 Rights as a Lender. With respect to its Commitments, L/C
Obligations and the Loans made by it, Wells Fargo in its capacity as a Lender
hereunder shall have the same rights and powers hereunder as any other Lender
and may exercise the same as though it were not acting in its agency capacity,
and the term "Lender" or "Lenders" shall, unless the context otherwise
indicates, include Agent in its individual capacity. Agent may (without having
to account therefor to any Lender) accept deposits from, lend money to and
generally engage in any kind of banking, trust, letter of credit, agency or
other business with Borrower (and any of its Affiliates) as if it were not
acting as Agent; and Agent may accept fees and other consideration from Borrower
(in addition to the fees heretofore agreed to between Borrower and Agent) for
services in connection with this Agreement or otherwise without having to
account for the same to the Lenders.

         Section 10.6 Indemnification. The Lenders agree to indemnify Agent (to
the extent not reimbursed under Section 11.3 or Section 11.4 hereof, but without
limiting the obligations of Borrower under said Sections 11.3 and 11.4), ratably
in accordance with the Lenders' respective Commitments (or, after termination of
the Commitments, ratably in accordance with the Loans held by them,
respectively), for any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever, REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY
THE NEGLIGENCE OF ANY INDEMNIFIED PARTIES, which may be imposed on, incurred by
or asserted against Agent in any way relating to or arising out of this
Agreement or any other Loan Document or any other documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
(including, without limitation, the costs and expenses which Borrower is
obligated to pay under Sections 11.3 and 11.4 hereof, interest, penalties,
attorneys' fees and amounts paid in settlement, but excluding, unless a Default
has occurred and is continuing, normal administrative costs and expenses
incident to the performance of its agency duties hereunder) or the enforcement
of any of the terms hereof or thereof or of any such other documents; provided
that no Lender shall be liable for any of the foregoing to the extent they arise
from the gross negligence or willful misconduct of the party to be indemnified.
The obligations of the Lenders under this Section 10.6 shall survive the
termination of this Agreement and the repayment of the Obligations.

         Section 10.7 Non-Reliance on Agent and Other Lenders. Each Lender
agrees that it has received current financial information with respect to
Borrower that it has, independently and without reliance on Agent or any other
Lender and based on such documents and information as it has deemed appropriate,
made its own credit analysis of Borrower and decision to enter into this
Agreement and that it will, independently and without reliance upon Agent or any
other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own analysis and decisions in
taking or not taking action under this

                                      -63-
<PAGE>

Agreement or any of the other Loan Documents. Agent shall not be required to
keep itself informed as to the performance or observance by Borrower of this
Agreement or any of the other Loan Documents or any other document referred to
or provided for herein or therein or to inspect the Properties or books of any
Person. Except for notices, reports and other documents and information
expressly required to be furnished to the Lenders by Agent hereunder or under
the other Loan Documents, Agent shall not have any duty or responsibility to
provide any Lender with any credit or other information concerning the affairs,
financial condition or business of any Person which may come into the possession
of Agent.

         Section 10.8 Failure to Act. Except for action expressly required of
Agent hereunder or under the other Loan Documents, Agent shall in all cases be
fully justified in failing or refusing to act hereunder and thereunder unless it
shall receive further assurances to its satisfaction by the Lenders of their
indemnification obligations under Section 10.6 hereof against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action.

         Section 10.9 Resignation or Removal of Agent. Subject to the
appointment and acceptance of a successor Agent as provided below, Agent may
resign at any time by giving notice thereof to the Lenders and Borrower, and
Agent may be removed at any time with or without cause by the Majority Lenders;
provided, that (i) any such resignation by Wells Fargo may also constitute its
resignation as L/C Issuer and Swing Line Lender provided the Agent complies with
the notice requirements of Section 11.6(g) hereof, and (ii) Agent shall continue
as Agent until such time as any successor shall have accepted appointment as
Agent hereunder. Upon any such resignation or removal, (i) the Majority Lenders
with the consent of Borrower unless an Event of Default has occurred and is
continuing shall have the right to appoint a successor Agent so long as such
successor Agent is also a Lender at the time of such appointment and (ii) the
Majority Lenders shall have the right to appoint a successor Agent that is not a
Lender at the time of such appointment so long as Borrower consents to such
appointment (which consent shall not be unreasonably withheld). If no successor
Agent shall have been so appointed by the Majority Lenders and accepted such
appointment within 30 days after the retiring Agent's giving of notice of
resignation or the Majority Lenders' removal of the retiring Agent, then the
retiring Agent may, on behalf of the Lenders, appoint a successor Agent. Any
successor Agent shall be a bank which has an office in the United States and a
combined capital and surplus of at least $250,000,000. Upon the acceptance of
any appointment as Agent hereunder by a successor Agent, such successor Agent
shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent and the retiring Agent shall be
discharged from its duties and obligations hereunder and under any other Loan
Documents and the retiring L/C Issuer's and Swing Line Lender's rights, powers
and duties as such shall be terminated, without any other or further act or deed
on the part of such retiring L/C Issuer or Swing Line Lender or any other
Lender, other than the obligation of the successor L/C Issuer to issue letters
of credit in substitution for the Letters of Credit, if any, outstanding at the
time of such succession or to make other arrangements satisfactory to the
retiring L/C Issuer to effectively assume the obligations of the retiring L/C
Issuer with respect to such Letters of Credit. Such successor Agent shall
promptly specify by notice to Borrower its Principal Office referred to in
Section 3.1 and Section 4 hereof. After any retiring Agent's resignation or
removal hereunder as Agent, the provisions of this Section 10 shall continue in
effect for its benefit in respect of any actions taken or omitted to be taken by
it while it was acting as Agent.

         Section 10.10 No Partnership. Neither the execution and delivery of
this Agreement nor any of the other Loan Documents nor any interest the Lenders,
Agent or any of them may now or hereafter have in all or any part of the
Obligations shall create or be construed as creating a partnership, joint
venture or other joint enterprise between the Lenders or among the Lenders and
Agent. The relationship between the Lenders, on the one hand, and Agent, on the
other, is and shall be that of principals and agent only, and nothing in this
Agreement or any of the other Loan Documents shall be construed to constitute
Agent as trustee or other fiduciary for any Lender or to impose on Agent any
duty, responsibility or obligation other than those expressly provided for
herein and therein.

         Section 10.11 Authority of Agent. Each Lender acknowledges that the
rights and responsibilities of Agent under this Agreement and the Loan Documents
with respect to any action taken by Agent or the exercise or non-exercise by
Agent of any option, right, request, judgment or other right or remedy provided
for herein or resulting or arising out of this Agreement and/or the other Loan
Documents shall, as between Agent and the Lenders, be governed by this Agreement
and by such other agreements with respect thereto as may exist from time to time
among them, but, as between Agent and Borrower, Agent shall be conclusively
presumed to be acting as agent for the Lenders with full and valid authority so
to act or refrain from acting; and Borrower shall not be under any obligation,
or entitlement, to make any inquiry respecting such authority.

         Section 10.12 Documentation Agent and Syndication Agent. Neither the
Documentation Agent nor the Syndication Agent, in their capacities as such,
shall have any duties or responsibilities under this Agreement.

SECTION 11. MISCELLANEOUS.

         Section 11.1 Waiver. No waiver of any Default or Event of Default shall
be a waiver of any other Default or Event of Default. No failure on the part of
Agent or any Lender to exercise and no delay in exercising, and no course of
dealing with respect to, any right, power or privilege under any Loan Document
shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power or privilege thereunder preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. The remedies
provided in the Loan Documents are cumulative and not exclusive of any remedies
provided by law or in equity.

         Section 11.2 Notices. All notices and other communications provided for
herein (including, without limitation, any modifications of, or waivers or
consents under, this Agreement) shall be given or made by telegraph, telecopy
(confirmed by mail), cable or other writing and telecopied, telegraphed, cabled,
mailed or delivered to the intended recipient at the "Address for Notices"
specified below its name on the signature pages hereof (or provided for in an
Assignment and Acceptance); or, as to any party hereto, at such other address as
shall be designated by such party in a notice (given in accordance with this
Section) (i) as to Borrower, to Agent, (ii) as to Agent, L/C Issuer or Swing
Line Lender, to Borrower and to each Lender, and (iii) as to any Lender, to
Borrower, Agent, L/C Issuer and Swing Line Lender. Except as otherwise provided
in this Agreement, all such notices or communications shall be deemed to have
been duly given when (i) transmitted by electronic mail, telecopier or delivered
to the telegraph or cable office, (ii) personally delivered (iii) one Business
Day after deposit with a nationally recognized overnight mail or delivery
service, postage prepaid or (iv) three Business Days' after deposit in a
receptacle maintained by the United States Postal Service, postage

                                      -65-
<PAGE>

prepaid, registered or certified mail, return receipt requested, in each case
given or addressed as aforesaid.

         Section 11.3 Expenses, Etc. Whether or not any Loan is ever made,
Borrower shall pay or reimburse within 10 Business Days after written demand (a)
Agent for paying the reasonable fees and expenses of legal counsel to Agent,
together with the reasonable fees and expenses of each local counsel to Agent,
in connection with the preparation, negotiation, execution and delivery of this
Agreement (including the exhibits and schedules hereto) and the other Loan
Documents and the making of the Loans, and any modification, supplement or
waiver of any of the terms of this Agreement or any other Loan Document; (b)
Agent for any reasonable and customary lien search fees; (c) Agent for
reasonable out-of-pocket expenses incurred in connection with the preparation,
documentation of the Loans or any of the Loan Documents; (d) Agent for paying
all transfer, stamp, documentary or other similar taxes, assessments or charges
levied by any governmental or revenue authority in respect of this Agreement or
any other Loan Document or any other document referred to herein or therein, and
(e) following the occurrence and during the continuation of an Event of Default,
any Lender or Agent for paying all amounts reasonably expended, advanced or
incurred by such Lender or Agent to satisfy any obligation of Borrower under
this Agreement or any other Loan Document, to collect the Obligations or to
enforce, protect, preserve or defend the rights of the Lenders or Agent under
this Agreement or any other Loan Document, including, without limitation, fees
and expenses incurred in connection with such Lender's or Agent's participation
as a member of a creditor's committee in a case commenced with Borrower or any
of its Restricted Subsidiaries as debtor under the Bankruptcy Code or other
similar law, fees and expenses incurred in connection with lifting the automatic
stay prescribed in Section 362 of the Bankruptcy Code and fees and expenses
incurred in connection with any action pursuant to Section 1129 of the
Bankruptcy Code and all other reasonable and customary out-of-pocket expenses
incurred by such Lender or Agent in connection with such matters, together with
interest thereon at the Past Due Rate on each such amount from the due date
until the date of reimbursement to such Lender or Agent.

         Section 11.4 Indemnification. Borrower shall indemnify each of Agent,
L/C Issuer, Swing Line Lender, the Lenders, and each affiliate thereof and their
respective directors, officers, employees and agents from, and hold each of them
harmless against, any and all losses, liabilities, claims or damages to which
any of them may become subject, REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART
BY THE NEGLIGENCE OF ANY INDEMNIFIED PARTIES, insofar as such losses,
liabilities, claims or damages arise out of or result from any (i) actual or
proposed use by Borrower of the proceeds of any extension of credit (whether a
Loan) by any Lender hereunder; (ii) breach by Borrower of this Agreement or any
other Loan Document; (iii) violation by Borrower or any of its Restricted
Subsidiaries of any Legal Requirement, or (iv) investigation, litigation or
other proceeding relating to any of the foregoing, and Borrower shall reimburse
Agent, L/C Issuer, Swing Line Lender, each Lender, and each Affiliate thereof
and their respective directors, officers, employees and agents, upon demand for
any reasonable and customary expenses (including reasonable and customary legal
fees) incurred in connection with any such investigation or proceeding;
provided, however, that Borrower shall not have any obligations pursuant to this
Section with respect to any losses, liabilities, claims, damages or expenses
incurred by the Person seeking indemnification by reason of the gross negligence
or willful misconduct of that Person or with respect to any disputes between or
among any of Agent, L/C Issuer, Swing Line Lender and Lenders. Nothing in this
Section is intended to limit the obligations of Borrower under any other
provision of this Agreement. In the case of any indemnification hereunder,
Agent, L/C Issuer, Swing Line

                                      -66-
<PAGE>

Lender, or the respective Lender, as appropriate, shall give written notice to
Borrower of any such claim or demand being made against an indemnified person
and Borrower shall have the non-exclusive right to join in the defense against
any such claim or demand, provided that if Borrower provides a defense, the
indemnified person shall bear its own cost of defense unless there is a conflict
of interests between Borrower and such indemnified person. No Indemnified Person
may settle any claim to be indemnified without the consent of Borrower, such
consent not to be unreasonably withheld or delayed.

         Section 11.5 Amendments, Etc. No amendment or modification of this
Agreement, the Notes, the Letter of Credit Applications, or any other Loan
Document shall in any event be effective against Borrower unless the same shall
be agreed or consented to in writing by such Person. No amendment, modification
or waiver of any provision of this Agreement, the Notes or any other Loan
Document, nor any consent to any departure by Borrower therefrom, shall in any
event be effective against the Lenders unless the same shall be agreed or
consented to in writing by the Majority Lenders, and each such waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given; provided, that no amendment, modification, waiver or consent
shall, unless in writing and signed by each Lender affected thereby, do any of
the following: (a) increase any Commitment of any of the Lenders (or reinstate
any termination or reduction of the Commitments) or subject any of the Lenders
to any additional obligations; (b) reduce the principal of, or interest on, any
Loan or L/C Borrowing or fee hereunder; (c) postpone or extend the Maturity Date
or any scheduled date fixed for any payment of principal of, or interest on, any
Loan, fee or other sum to be paid hereunder or waive any Event of Default
described in Section 9.1(a) hereof; (d) change the percentage of any of the
Commitments or of the aggregate unpaid principal amount of any of the Loans or
L/C Obligations, or the percentage of Lenders, which shall be required for the
Lenders or any of them to take any action under this Agreement, or (e) change
any provision contained in Sections 7.9, 11.3 or 11.4 hereof or this Section
11.5. Notwithstanding anything in this Section 11.5 to the contrary, no
amendment, modification, waiver or consent shall be made with respect to Section
10 without the consent of Agent to the extent it affects Agent, as Agent.

         Section 11.6 Successors and Assigns.

                  (a) The provisions of this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby, except that the Borrower may not assign or otherwise
transfer any of its rights or obligations hereunder, other than as permitted by
Section 8.5 hereof, without the prior written consent of each Lender and no
Lender may assign or otherwise transfer any of its rights or obligations
hereunder except (i) to an Eligible Assignee in accordance with the provisions
of paragraph (b) of this Section, (ii) by way of participation in accordance
with the provisions of paragraph (d) of this Section or (iii) by way of pledge
or assignment of a security interest subject to the restrictions of paragraph
(f) of this Section (and any other attempted assignment or transfer by any party
hereto shall be null and void). Nothing in this Agreement, expressed or implied,
shall be construed to confer upon any Person (other than the parties hereto,
their respective successors and assigns permitted hereby, Participants to the
extent provided in paragraph (d) of this Section and, to the extent expressly
contemplated hereby, the Related Parties of each of the Agent and the Lenders)
any legal or equitable right, remedy or claim under or by reason of this
Agreement.

                  (b) Any Lender may at any time assign to one or more Eligible
Assignees all or a portion of its rights and obligations under this Agreement
(including all or a portion of its

                                      -67-
<PAGE>

Commitment and the Loans (including for purposes of this subsection (b),
participations in L/C Obligations and in Swing Line Loans) at the time owing to
it); provided that (i) except in the case of an assignment of the entire
remaining amount of the assigning Lender's Commitment and the Loans at the time
owing to it or in the case of an assignment to a Lender or an Affiliate of a
Lender or an Approved Fund with respect to a Lender, the aggregate amount of the
Commitment (which for this purpose includes Loans outstanding thereunder) or, if
the applicable Commitment is not then in effect, the principal outstanding
balance of the Loan of the assigning Lender subject to each such assignment
(determined as of the date the Assignment and Acceptance with respect to such
assignment is delivered to the Agent or, if "Trade Date" is specified in the
Assignment and Acceptance, as of the Trade Date) shall not be less than
$5,000,000, in the case of any assignment in respect of a revolving facility,
unless each of the Agent and, so long as no Event of Default has occurred and is
continuing, the Borrower otherwise consent (each such consent not to be
unreasonably withheld or delayed); (ii) each partial assignment shall be made as
an assignment of a proportionate part of all the assigning Lender's rights and
obligations under this Agreement with respect to the Loan or the Commitment
assigned; (iii) any assignment of a Commitment must be approved by the Agent
and, unless an Event of Default has occurred and is continuing, the Borrower
(each such approval not to be unreasonably withheld or delayed; and (iv) the
parties to each assignment shall execute and deliver to the Agent, at least five
days prior to the proposed effective date of such assignment, an Assignment and
Acceptance in substantially the form of Exhibit D hereto (each an "Assignment
and Acceptance"), together with a processing and recordation fee of $3,000, and
the Eligible Assignee, if it shall not be a Lender, shall deliver to the Agent
an Administrative Questionnaire. Subject to acceptance and recording thereof by
the Agent pursuant to paragraph (c) of this Section, from and after the
"Effective Date" specified in each Assignment and Acceptance, the Eligible
Assignee thereunder shall be a party to this Agreement and, to the extent of the
interest assigned by such Assignment and Acceptance, have the rights and
obligations of a Lender under this Agreement, and the assigning Lender
thereunder shall, to the extent of the interest assigned by such Assignment and
Acceptance, be released from its obligations under this Agreement (and, in the
case of an Assignment and Acceptance covering all of the assigning Lender's
rights and obligations under this Agreement, such Lender shall cease to be a
party hereto) but shall continue to be entitled to the benefits of Sections
3.3(c)(ii), 3.3(c)(iv), 11.4 and 4.1(f) with respect to facts and circumstances
occurring prior to the effective date of such assignment. Any assignment or
transfer by a Lender of rights or obligations under this Agreement that does not
comply with this paragraph shall be treated for purposes of this Agreement as a
sale by such Lender of a participation in such rights and obligations in
accordance with paragraph (d) of this Section, subject to compliance with the
requirements of such paragraph (d).

                  (c) The Agent, acting solely for this purpose as an agent of
the Borrower, shall maintain at one of its offices a copy of each Assignment and
Acceptance delivered to it and a register for the recordation of the names and
addresses of the Lenders, and the Commitments of, and principal amounts of the
Loans and L/C Obligations owing to, each Lender pursuant to the terms hereof
from time to time (the "Register"). The entries in the Register, in the absence
of manifest error, shall be conclusive, and the Borrower, the Agent and the
Lenders may treat each Person whose name is recorded in the Register pursuant to
the terms hereof as a Lender hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary. The Register shall be available for
inspection by the Borrower and any Lender, at any reasonable time and from time
to time upon reasonable prior notice.

                                      -68-
<PAGE>

                  (d) Any Lender may at any time, without the consent of, or
notice to, the Borrower or the Agent, sell participations to any Person (other
than a natural person or the Borrower or any of the Borrower's Affiliates or
Subsidiaries) (each, a "Participant") in all or a portion of such Lender's
rights and/or obligations under this Agreement (including all or a portion of
its Commitment and/or the Loans (including such Lender's participations in L/C
Obligations and/or Swing Line Loans) owing to it); provided that (i) such
Lender's obligations under this Agreement shall remain unchanged, (ii) such
Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations and (iii) the Borrower, the Agent and the other
Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement. Any
agreement or instrument pursuant to which a Lender sells such a participation
shall provide that such Lender shall retain the sole right to enforce this
Agreement and to approve any amendment, modification or waiver of any provision
of this Agreement; provided that such agreement or instrument may provide that
such Lender will not, without the consent of the Participant, agree to any
amendment, modification or waiver described in clauses (a) through (e) of
Section 11.5 that affects such Participant. Subject to paragraph (e) of this
Section, the Borrower agrees that each Participant shall be entitled to the
benefits of Sections 3.3(c)(ii), 3.3(c)(iv) and 4.1(f) to the same extent (but
only to the extent of its transferor Lender) as if it were a Lender and had
acquired its interest by assignment pursuant to paragraph (b) of this Section.
To the extent permitted by law, each Participant also shall be entitled to the
benefits of Section 9.2 as though it were a Lender (but only to the extent of
its transferor Lender), provided such Participant agrees to be subject to
Section 4.5 as though it were a Lender.

                  (e) A Participant shall not be entitled to receive any greater
payment under Sections 3.3(c)(ii) and 4.1(f) than the applicable Lender would
have been entitled to receive with respect to the participation sold to such
Participant, unless the sale of the participation to such Participant is made
with the Borrower's prior written consent. A Participant which is organized
under the laws of a jurisdiction outside the United States shall not be entitled
to the benefits of Section 4.1(f) unless the Borrower is notified of the
participation sold to such Participant and such Participant agrees, for the
benefit of the Borrower, to comply with Section 11.13 as though it were a
Lender.

                  (f) Any Lender may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement to secure
obligations of such Lender, including without limitation any pledge or
assignment to secure obligations to a Federal Reserve Bank; provided that no
such pledge or assignment shall release such Lender from any of its obligations
hereunder or substitute any such pledgee or assignee for such Lender as a party
hereto.

                  (g) Notwithstanding anything to the contrary contained herein,
if at any time Wells Fargo assigns all of its Commitment and Loans pursuant to
subsection (b) above, or resigns as Agent pursuant to Section 10.9 hereof, Wells
Fargo may, (i) upon 30 days' notice to the Borrower and the Lenders, resign as a
L/C Issuer and/or (ii) upon five Business Days' notice to the Borrower and the
Lenders, terminate the Swing Line. In the event of any such termination of the
Swing Line or resignation as L/C Issuer, the Borrower shall be entitled to
appoint from among the Lenders a successor Swing Line Lender or L/C Issuer
hereunder, subject to the concurrence of such Lender; provided, however, that no
failure by the Borrower to appoint any such successor shall affect the
termination of the Swing Line, as the case may be. Wells Fargo shall retain all
the rights and obligations of a L/C Issuer hereunder with respect to all Letters
of Credit outstanding as of the effective date of its resignation as a L/C
Issuer and all L/C

                                      -69-
<PAGE>

Obligations with respect thereto (including the right to require the Lenders to
make Base Rate Borrowings or fund participations in Unreimbursed Amounts
pursuant to Section 2.3(c) hereof). If Wells Fargo terminates the Swing Line, it
shall retain all the rights of the Swing Line Lender provided for hereunder with
respect to Swing Line Loans made by it and outstanding as of the effective date
of such termination, including the right to require the Lenders to make Base
Rate Borrowings or fund participations in outstanding Swing Line Loans pursuant
to Section 2.2(c) hereof.

         Section 11.7 Limitation of Interest. The parties hereto intend to
strictly comply with all applicable federal and Texas laws, including applicable
usury laws (or the usury laws of any jurisdiction whose usury laws are deemed to
apply to the Notes or any other Loan Documents). Accordingly, the provisions of
this Section 11.7 shall govern and control over every other provision of this
Agreement or any other Loan Document which conflicts or is inconsistent with
this Section, even if such provision declares that it controls. As used in this
Section, 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 or as compensation
for something other than the use, forbearance or detention of money 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 Borrower or any other
Person be obligated to pay, or Agent or any Lender have any right or privilege
to reserve, receive or retain, (a) any interest in excess of the maximum amount
of nonusurious interest permitted under the laws of the State of Texas or the
applicable laws (if any) of the United States or of any other jurisdiction, or
(b) total interest in excess of the amount which such Person could lawfully have
contracted for, reserved, received, retained or charged had the interest been
calculated for the full term of the Obligations at the Ceiling Rate. The daily
interest rates to be used in calculating interest at the Ceiling Rate shall be
determined by dividing the applicable Ceiling Rate per annum by the number of
days in the calendar year for which such calculation is being made. None of the
terms and provisions contained in this Agreement or in any other Loan Document
(including, without limitation, Section 9.1 hereof) which directly or indirectly
relate to interest shall ever be construed without reference to this Section
11.7, or be construed to create a contract to pay for the use, forbearance or
detention of money at an interest rate in excess of the Ceiling Rate. If the
term of any Obligation is shortened by reason of acceleration of maturity as a
result of any Default or by any other cause, or by reason of any required or
permitted prepayment, and if for that (or any other) reason Agent or any Lender
at any time, including but not limited to, the stated maturity, is owed or
receives (and/or has received) interest in excess of interest calculated at the
Ceiling Rate, then and in any such event all of any such excess interest shall
be canceled 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 Person, it shall be credited pro tanto against the then-outstanding
principal balance of Borrower's obligations to such Person, 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.

         Section 11.8 Survival. The obligations of Borrower under Sections 7.9,
11.3 and 11.4 hereof and all other obligations of Borrower in any other Loan
Document (to the extent stated therein) and the obligations of the Lenders under
Sections 4.1(f), 10.6, 11.7, 11.13 and 11.16

                                      -70-

hereof, shall, notwithstanding anything herein to the contrary, survive the
repayment of the Loans and the termination of the Commitments.

         Section 11.9 Captions. Captions and section headings appearing herein
are included solely for convenience of reference and are not intended to affect
the interpretation of any provision of this Agreement.

         Section 11.10 Counterparts. This Agreement may be executed in any
number of counterparts, all of which taken together shall constitute one and the
same agreement and any of the parties hereto may execute this Agreement by
signing any such counterpart.

         Section 11.11 Governing Law. THIS AGREEMENT AND (EXCEPT AS THEREIN
PROVIDED) THE OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE APPLICABLE LAWS OF THE STATE OF TEXAS AND THE UNITED STATES
OF AMERICA FROM TIME TO TIME IN EFFECT.

         Section 11.12 Severability. Whenever possible, each provision of the
Loan Documents shall be interpreted in such manner as to be effective and valid
under applicable law. If any provision of any Loan Document shall be invalid,
illegal or unenforceable in any respect under any applicable law, the validity,
legality and enforceability of the remaining provisions of such Loan Document
shall not be affected or impaired thereby.

         Section 11.13 Tax Forms. Each Lender which is organized under the laws
of a jurisdiction outside the United States shall, on the day of the initial
borrowing from each such Lender hereunder and from time to time thereafter if
requested by Borrower or Agent, provide Agent and Borrower with the forms
prescribed by the Internal Revenue Service of the United States certifying as to
such Lender's status for purposes of determining exemption from United States
withholding taxes with respect to all payments to be made to such Lender
hereunder or other documents satisfactory to such Lender, Borrower and Agent
indicating that all payments to be made to such Lender hereunder are not subject
to United States withholding tax or are subject to such tax at a rate reduced by
an applicable tax treaty. If a Lender determines, as a result of any change in
either (i) applicable law, regulation or treaty, or in any official application
thereof or (ii) its circumstances, that it is unable to submit any form or
certificate that it is obligated to submit pursuant to this Section, or that it
is required to withdraw or cancel any such form or certificate previously
submitted, it shall promptly notify Borrower and Agent of such fact. Unless
Borrower and Agent shall have received such forms or such documents indicating
that payments hereunder are not subject to United States withholding tax or are
subject to such tax at a rate reduced by an applicable tax treaty, Borrower or
Agent shall withhold taxes from such payments at the applicable statutory rate.
Each Lender agrees to indemnify and hold harmless from any United States taxes,
penalties, interest and other expenses, costs and losses incurred or payable by
(i) Agent as a result of such Lender's failure to submit any form or certificate
that it required to provide pursuant to this Section or (ii) Borrower or Agent
as a result of their reliance on any representation, form or certificate which
such Lender has provided to them pursuant to this Section.

         Section 11.14 Conflicts Between This Agreement and the Other Loan
Documents. In the event of any conflict between the terms of this Agreement and
the terms of any of the other Loan Documents, the terms of this Agreement shall
control.

         Section 11.15 Limitation on Charges; Substitute Lenders;
Non-Discrimination. Anything in Sections 3.3(c) or 7.9 notwithstanding:

                  (a) Borrower shall not be required to pay to any Lender
reimbursement or indemnification with regard to any costs or expenses described
in such Sections, unless such Lender notifies Borrower of such costs or expenses
within 90 days after the date paid or incurred;

                  (b) none of the Lenders shall be permitted to pass through to
Borrower charges and costs under such Sections on a discriminatory basis (i.e.,
which are not also passed through by such Lender to other customers of such
Lender similarly situated where such customer is subject to documents providing
for such pass through); and

                  (c) if any Lender elects to pass through to Borrower any
material charge or cost under such Sections or elects to terminate the
availability of LIBOR Borrowings for any material period of time, Borrower may,
within 60 days after the date of such event and so long as no Default shall have
occurred and be continuing, elect to terminate such Lender as a party to this
Agreement; provided that, concurrently with such termination Borrower shall (i)
if Agent and each of the other Lenders shall consent, pay that Lender all
principal, interest and fees and other amounts owed to such Lender through such
date of termination or (ii) have arranged for another financial institution
approved by Agent (such approval not to be unreasonably withheld or delayed) as
of such date, to become a substitute Lender for all purposes under this
Agreement in the manner provided in Section 11.6; provided further that, prior
to substitution for any Lender, Borrower shall have given written notice to
Agent of such intention and the Lenders shall have the option, but no
obligation, for a period of 60 days after receipt of such notice, to increase
their Commitments in order to replace the affected Lender in lieu of such
substitution.

         Section 11.16 Confidentiality. Each Lender agrees to exercise its best
efforts to keep any information delivered or made available by Borrower which is
clearly indicated to be confidential information, confidential from anyone other
than Persons employed or retained by such Lender or any of its Affiliates who
are or are expected to become engaged in evaluating, approving, structuring or
administering the Loans; provided that nothing herein shall prevent any Lender
from disclosing such information (a) to any other Lender; (b) pursuant to
subpoena or upon the order of any court or administrative agency; (c) upon the
request or demand of any regulatory agency or authority having jurisdiction over
such Lender; (d) which has been publicly disclosed; (e) to the extent reasonably
required in connection with any litigation to which Agent, any Lender, Borrower
or their respective Affiliates may be a party; (f) to the extent reasonably
required in connection with the exercise of any remedy hereunder; (g) to such
Lender's bank counsel and independent auditors; and (h) to any actual or
proposed participant or assignee of all or part of its rights hereunder which
has agreed in writing to be bound by the provisions of this Section.

         Notwithstanding anything to the contrary, "information" shall not
include, and the Agent and each Lender may disclose without limitation of any
kind, any information with respect to the "tax treatment" and "tax structure"
(in each case, within the meaning of Treasury Regulation Section 1.6011-4) of
the transactions contemplated hereby and all materials of any kind (including
opinions or other tax analyses) that are provided to the Agent or such Lender
relating to such tax treatment and tax structure; provided that with respect to
any document or similar item that in either case contains information concerning
the tax treatment or tax structure of the

                                      -72-
<PAGE>

transaction as well as other information, this sentence shall only apply to such
portions of the document or similar item that relate to the tax treatment or tax
structure of the Loans, Letters of Credit and transactions contemplated hereby.

         Section 11.17 Refinancing of Obligations Under Existing Credit
Agreement. This Agreement constitutes a refinancing of the "Obligations" under
the Existing Credit Agreement. On the date hereof:

         (a) The Borrower shall pay all accrued and unpaid commitment fees
outstanding under the Existing Credit Agreement;

         (b) Each "Loan" under the Existing Credit Agreement shall be repaid
with the proceeds of the initial Loan hereunder, and each Lender that is party
to the Existing Credit Agreement hereby waives any requirement that the Borrower
pay any "Funding Loss", as defined in the Existing Credit Agreement, in
connection with such repayment;

         (c) each Existing L/C outstanding under the Existing Credit Agreement
shall be deemed to have been issued under this Agreement without payment of any
further fronting fee (but subject to the other fees set forth in Sections 2.3(i)
and 2.3(j)); and

         (d) the Existing Credit Agreement and the commitments thereunder shall
terminate.

         Section 11.18 Waiver of Right to Trial by Jury. EACH PARTY TO THIS
AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY
CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR
ANY OF THEM WITH RESPECT TO ANY LOAN DOCUMENT, OR THE TRANSACTIONS RELATED
THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER
FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND
CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED
BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN
ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN
EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT
TO TRIAL BY JURY.

         Section 11.19 NOTICE PURSUANT TO TEX. BUS. & COMM. CODE SECTION 26.02.
THE CREDIT AGREEMENT AND ALL OTHER LOAN DOCUMENTS EXECUTED BY ANY OF THE PARTIES
PRIOR HERETO OR SUBSTANTIALLY CONCURRENTLY HEREWITH CONSTITUTE A WRITTEN CREDIT
AGREEMENT WHICH REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT
BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.

OCEANEERING INTERNATIONAL, INC.                                    Exhibit 10.09
2003 BONUS AWARD PLAN

On March 7, 2003, a 2003 Bonus Award Plan under the 2002 Incentive Plan or any
successor Incentive Plan was approved by the Company's Board of Directors to be
administered by its Compensation Committee. Individuals were nominated and
approved for inclusion in the Plan and reviewed after final results were
completed. Recommendations for cash bonus awards were based on the
accomplishment of results (Individual, Profit Center and Total Company) in order
to determine the amount of award, if any, to be made. Awardees must be amongst
the nominated group for eligibility, and be employed by the Company at the time
of funding. Bonuses are earned when paid. Individuals, as designated, are
subject to a maximum bonus eligibility of 10%-125% of current base salary.

The 2003 Bonus Award Plan is based on achieving specific results by the
Individual, his Profit Center and the Total Company. In order to integrate each
of these performances in a fashion that benefits the Shareholders and Employees,
each item is interrelated. The amount of award recommendation was based on the
following methodology:

Individual Coefficient

The Individual Coefficient is determined by taking the individual's weighted
average evaluation of objectives achieved times the individual's salary maximum.
This is the beginning step in determining the final award. An individual's
performance must meet certain minimum criteria or he is eliminated from bonus
award consideration.

Profit Center Results Contribution

The Profit Center Contribution is determined by comparing the Profit Center Net
Income Objective with the results achieved and determining the Contribution to
the Individual Coefficient.

Should the Profit Center results be below a specified amount, all the
individuals in that Profit Center may be eliminated from the Award Program. The
Chief Executive Officer may review the performance of areas within the region on
a case-by-case basis and take appropriate action. Should the actual results be
equal to or greater than such specified amount, the individual becomes eligible
for an award.

Oceaneering International, Inc. Results Contribution

The Company Results Contribution is determined by comparing the Company's Net
Income Result with the Objective planned. The results achieved determine the
multiplier used. Thus, an individual may, subject to the determined maximum, be
recommended for an award equal to the Individual Coefficient times the Profit
Center Contribution times the Company Results Contribution times current base
salary.

The 2003 Bonus Award Plan is in effect for 2003. It is extremely important that
the Company continue improved results. All participants must be committed to a
reward system based on achieving results. The Company is entrepreneurially
oriented and must use its maximum creativity, effort and determination in
achieving individual results that collectively increases its Shareholders' Net
Wealth. The 2003 Bonus Award Plan is structured to foster that position.
