Advances to the Borrower from time to time from the Effective Date to and

Commitments by means of Revolving Credit Advances. Each Revolving Credit Advance
made by each Bank shall be made and maintained at such Bank's Principal Office.

bear interest prior to maturity at a varying rate per annum equal from day to
day to the lesser of (a) the Maximum Rate, and (b) the Applicable Rate. If at
any time the Applicable Rate for any Advance shall exceed the Maximum Rate,
thereby causing the interest accruing on such Advance to be limited to the
Maximum Rate, then any subsequent reduction in the Applicable Rate for such
Advance shall not reduce the rate of interest on such Advance below the Maximum
Rate until the aggregate amount of interest accrued on such Advance equals the
aggregate amount of interest which would have accrued on such Advance if the
Applicable Rate had at all times been in effect. Accrued and unpaid interest on
the Advances shall be due and payable as follows:

            (a) on each Payment Date; and

Default Rate. Such interest shall be payable on the earlier of demand or the
Revolving Commitment Termination Date, and shall accrue until the earlier of (i)
waiver or cure of the applicable Event of Default, (ii) agreement by the
Required Banks to rescind the charging of interest at the Default Rate, or (iii)
payment in full of the Obligations.

the Agent for the account of each Bank a commitment fee on the daily average
unused amount of such Bank's Revolving Credit Commitment for the period from and
including the Effective Date to and including the Revolving Credit Termination
Date at the rate per annum equal to the Applicable Margin in effect on the date
such payment is due, based on a 360 day year and the actual number of days
elapsed; provided that (a) the amount of any Swing Line Advances that may be
outstanding from time to time shall not be considered usage of the Revolving
Credit Commitment and (b) the face amount of outstanding Letters of Credit shall
be considered usage of the Revolving Credit Commitment. The accrued commitment
fee shall be payable in arrears on each Quarterly Fee Payment Date and on the
Revolving Credit Termination Date.

      Section 2.7 Reduction or Termination of Revolving Credit Commitment. The
Borrower shall have the right to terminate in whole or reduce in part the unused
portion of the Revolving Credit Commitments upon at least three Business Days'
prior notice (which notice shall be irrevocable) to the Agent specifying the
effective date thereof, whether a termination or reduction is being made, and
the amount of any partial reduction; provided, however, that the Revolving
Credit Commitments shall never be reduced below an amount equal to the aggregate
outstanding Letter of Credit Liabilities unless cash collateralized. Each
partial reduction shall be in the amount of $1,000,000 or a greater integral
multiple of $500,000, and the Borrower shall simultaneously prepay the Advances
by the amount by which the unpaid principal amount of the Advances plus the
Letter of Credit Liabilities exceeds the Revolving Credit Commitments (after
giving effect to such notice) plus accrued and unpaid interest on the principal
amount so prepaid. Subject to Section 2.10 hereof, the Revolving Credit
Commitments may not be reinstated after they have been terminated or reduced.

      Section 2.8 Letters of Credit.

            (a) Subject to, and upon the terms, conditions, covenants and
      agreements contained herein and in the Letter of Credit Agreements, prior
      to the Revolving Credit Termination Date, the Issuing Bank agrees to issue

      any time exceed $5,000,000, and (ii) the aggregate principal amount
      outstanding of all Revolving Credit Advances, the Letter of Credit
      Liabilities, and the aggregate principal amount outstanding of all Swing
      Line Advances may at no time exceed the aggregate Revolving Credit
      Commitments. In the event of an actual conflict between the terms and

            (b) On or before the Revolving Credit Termination Date, the Borrower
      agrees to deposit with and pledge to the Agent cash or Cash Equivalent
      Investments in an amount equal to 110% of all outstanding Letter of Credit
      Liabilities.

      Section 2.9 Payments and Reimbursement Under Letters of Credit.

            (a) Payments. Issuing Bank shall promptly notify the Agent and the
      Borrower of the date and amount of any draft presented for honor under any
      Letter of Credit (but failure to give notice will not affect the
      Borrower's obligations under this Agreement). Issuing Bank shall pay the
      requested amount upon presentment of a draft unless presentment on its
      face does not comply with the terms of the applicable Letter of Credit.
      When making payment, Issuing Bank may disregard (i) any default or
      potential default that exists under any other agreement and (ii)
      obligations under any other agreement that have or have not been performed
      by the beneficiary or any other Person (and Issuing Bank is not liable for
      any of those obligations absent gross negligence or willful misconduct).
      Issuing Bank shall promptly pay to the Agent for the Agent to promptly
      distribute reimbursement payments received from the Borrower to all Banks
      according to their Percentages.

            (b) Reimbursement Obligation of the Borrower. To induce Issuing Bank
      to issue and maintain Letters of Credit, and to induce Banks to
      participate in issued Letters of Credit, the Borrower agrees to pay or
      reimburse Issuing Bank (or cause another Obligated Party to pay or
      reimburse Issuing Bank) (i) the amount paid by Issuing Bank pursuant to a
      draw on a Letter of Credit on the same day such payment is made, and (ii)
      on demand, the amount of any additional reasonable fees Issuing Bank
      customarily charges for amending Letter of Credit Agreements, for honoring
      drafts under Letters of Credit, and for taking similar action in
      connection with Letters of Credit. If the Borrower or another Obligated
      Party has not reimbursed Issuing Bank for any drafts when reimbursement is
      required under this section, then the Agent is irrevocably authorized to
      fund the Borrower's reimbursement obligations as a Base Rate Advance if
      proceeds are available under the Revolving Credit Commitment and if the
      conditions in this Agreement for such an Advance (other than any notice
      requirements or minimum funding amounts) have, to the Agent's knowledge,
      been satisfied. The proceeds of that Advance shall be advanced directly to
      Issuing Bank to pay the Borrower's unpaid reimbursement obligations. If
      funds cannot be advanced under the Revolving Credit Commitment, then the
      Borrower's reimbursement obligation shall constitute a demand obligation.
      The Borrower's obligations under this section are absolute and
      unconditional under any and all circumstances and irrespective of any
      setoff, counterclaim, or defense to payment that the Borrower may have at
      any time against Issuing Bank or any other Person. From the date that
      Issuing Bank pays a draft under a Letter of Credit until the Borrower or
      another

                                       20
<PAGE>

      Obligated Party either reimburses or is obligated to reimburse Issuing
      Bank for that draft under this section, the amount of that draft bears
      interest payable to Issuing Bank at the rate then applicable to Base Rate
      Advances. From the due date of the respective amounts due under this
      section, to the date paid (including any payment from proceeds of a Base
      Rate Advance), unpaid reimbursement amounts accrue interest that is
      payable on demand at the Default Rate.

            (c) Obligation of Banks. If an Obligated Party fails to reimburse
      Issuing Bank as provided herein by the date on which reimbursement is due
      hereunder, and funds cannot be advanced under the Revolving Credit
      Commitment to satisfy the reimbursement obligations, then the Agent shall
      promptly notify each Bank of such failure, of the date and amount paid,
      and of each Bank's Percentage of the unreimbursed amount as a
      participation in such unreimbursed amounts. Each Bank shall promptly and
      unconditionally make available to the Agent in immediately available funds
      its Percentage of the unpaid reimbursement obligation, subject to the
      limitations of Section 2.1. Funds are due and payable to the Agent before
      the close of business on the Business Day when the Agent gives notice to
      each Bank of such reimbursement failure (if notice is given before 11:00
      a.m. (Houston time)) or on the next succeeding Business Day (if notice is
      given after 11:00 a.m. (Houston time)). All amounts payable by any Bank
      accrue interest after the due date at the Federal Funds Rate from the day
      the applicable draft or draw is paid by the Agent to (but not including)
      the date the amount is paid by the Bank to the Agent. Upon receipt of
      those funds, the Agent shall make them available to Issuing Bank.

            (d) Duties of Issuing Bank. Issuing Bank agrees with each Bank that
      it will exercise and give the same care and attention to each Letter of
      Credit as it gives to its other letters of credit. Each Bank and the
      Borrower agree that, in paying any draft under any Letter of Credit,
      Issuing Bank has no responsibility to obtain any document (other than any
      documents expressly required by the respective Letter of Credit) or to
      ascertain or inquire as to any document's validity, enforceability,
      sufficiency, accuracy, or genuineness or the authority of any Person
      delivering it. Neither Issuing Bank nor its representatives will be liable
      to any Bank or any Obligated Party for any Letter of Credit's use or for
      any beneficiary's acts or omissions. Any action, inaction, error, delay,
      or omission taken or suffered by Issuing Bank or any of its
      representatives in connection with any Letter of Credit, applicable drafts
      or documents, or the transmission, dispatch, or delivery of any related
      message or advice, if in good faith and in conformity with applicable laws
      and in accordance with the standards of care specified in the Uniform
      Customs and Practices for Documentary Credits (1993 Revision),
      International Chamber of Commerce Publication No. 500 (as amended or
      modified), is binding upon the Obligated Parties and Banks and, except as
      expressly provided herein, does not place Issuing Bank or any of its
      representatives under any resulting liability to any Obligated Party or
      any Bank. Agent is not liable to any Obligated Party or any Bank for any
      action taken or omitted, in the absence of gross negligence or willful
      misconduct, by Issuing Bank or its representative in connection with any
      Letter of Credit.

      Section 2.10 Optional Commitment Increase.

                                       21

<PAGE>

            (a) Optional Increase Request. The Borrower may, at any time and
      from time to time prior to March 31, 2007, so long as no Default or Event
      of Default exists, request that the Revolving Credit Commitments be
      increased (the "Increase Amount") in an aggregate amount not to exceed
      $25,000,000 (each, a "Commitment Increase"), provided that any such
      request shall be made in writing (an "Increase Request") by the Borrower
      and delivered to the Agent. Promptly upon receipt of an Increase Request,
      the Agent shall notify the Banks of such request.

            (b) Banks' Response to Increase Request. Each Bank shall have the
      right, but not the obligation, to elect to increase its respective
      Revolving Credit Commitment by an amount not to exceed the Increase
      Amount, which election shall be made by notice from each Bank to the Agent
      given not later than 21 days after the date notified of the Increase
      Request by Agent (the "Response Date"), and shall specify the amount of
      the proposed increase in such Bank's Revolving Credit Commitment. If any
      Bank shall fail to give such notice to Agent by the Response Date, such
      Bank shall be deemed to have elected not to increase its Revolving Credit
      Commitment in connection with such Increase Request.

            (c) Joinder of Additional Banks. If the aggregate amount of the
      proposed increases in the Revolving Credit Commitments of all Banks making
      an election to increase their respective Revolving Credit Commitment
      (each, an "Increasing Bank") does not equal or exceed the Increase Amount,
      then the Agent shall use commercially reasonable efforts to add one or
      more financial institutions (which must be Eligible Assignees reasonably
      satisfactory to the Borrower and the Agent) as Banks (each an "Additional
      Bank"), which Additional Banks shall have aggregate Revolving Credit
      Commitments not greater than an amount equal to (i) the Increase Amount,
      less (ii) any increases in the Revolving Credit Commitments of the
      Increasing Banks.

            (d) Adjustments to Commitments.

                  (i) If the aggregate amount of the proposed increases to the
            Revolving Credit Commitments of all Increasing Banks is in excess of
            the Increase Amount, then (A) the Increase Amount shall be allocated
            pro rata among the Increasing Banks based on the respective amounts
            of the proposed increases to the Revolving Credit Commitment of each
            such Increasing Bank, provided that any Bank which proposes to
            increase its Revolving Credit Commitment by an amount equal to its
            Percentage of the Increase Amount shall be allocated its Percentage
            of the Increase Amount; (B) the Revolving Credit Commitment of each
            such Increasing Bank shall be increased by the amount allocated to
            such Increasing Bank pursuant to clause (A) of this Section
            2.10(d)(i); and (C) the Percentages of all Banks shall be adjusted
            accordingly.

                  (ii) If the aggregate amount of the proposed increases to the
            Revolving Credit Commitments of all Increasing Banks equals the
            Increase Amount, then (A) the Revolving Credit Commitment of each
            such Increasing Bank shall be increased by the amount of such
            Increasing

                                       22

<PAGE>

            Bank's proposed increase, and (B) the Percentages of all Banks shall
            be adjusted accordingly.

                  (iii) If the aggregate amount of the proposed increases to the
            Revolving Credit Commitments of all Increasing Banks is less than
            the Increase Amount, then (A) the Revolving Credit Commitment of
            each such Increasing Bank shall be increased by the respective
            amount of its proposed increase; (B) the amount of the Revolving
            Credit Commitments shall be further increased by the portion of the
            Increase Amount allocated to Additional Banks, if any; and (C) the
            Percentages of all Banks shall be adjusted accordingly.

            (e) Notes. Upon any increase in the Revolving Credit Commitments
      pursuant to this Section, the Borrower will execute and deliver (i) a
      replacement Revolving Credit Note to each Increasing Bank, each in the
      principal amount of the Revolving Credit Commitment of such Increasing
      Bank, as increased in accordance with subsection (d) of this Section 2.10,
      and (ii) a new Revolving Credit Note to each Additional Bank made party to
      this Agreement in connection therewith, each in the principal amount of
      such Additional Bank's Revolving Credit Commitment.

            (f) Documentation. The Borrower and the Agent shall execute
      appropriate documentation to add each Additional Bank as a party to this
      Agreement, whereupon such Additional Bank shall have all of the rights and
      obligations of a Bank hereunder and under the other Loan Documents. The
      Obligated Parties shall execute and deliver appropriate documentation and
      pay any and all mortgage or other taxes that are lawfully due and payable
      in connection with a Commitment Increase to preserve and protect the Liens
      of the Agent in the Collateral and the perfection and priority of such
      Liens.

            (g) Payment; Amortization. (i) Each Additional Bank shall pay to the
      Agent for the account of the other Banks an amount equal to its Percentage
      of outstanding Revolving Credit Advances, (ii) each Increasing Bank shall
      pay to the Agent for the account of the other Banks the amount necessary
      so that such Increasing Bank has advanced an amount equal to its
      Percentage (as adjusted in accordance with subsection (d) of this Section
      2.10) of outstanding Revolving Credit Advances, and (iii) such amount so
      paid by each Additional Bank and each Increasing Bank shall constitute a
      Revolving Credit Advance by such Additional Bank or Increasing Bank under
      its Revolving Credit Note and a payment of principal to the other Banks
      under their respective Revolving Credit Notes and the outstanding
      principal balances of the respective Revolving Credit Notes shall be
      increased or reduced accordingly.

            (h) Effects of Increase. Upon and as of the date of the addition of
      any Additional Bank to the Agreement or the increase of the Revolving
      Credit Commitment of any Increasing Bank, (i) the Revolving Credit
      Commitments of the other Banks (other than other Increasing Banks) shall
      remain unchanged, and (ii) solely with respect to Revolving Credit
      Commitments, each of the other Banks shall be deemed to have sold and
      transferred to such Additional Bank or such Increasing Bank, as the case
      may be, and such Additional Bank or Increasing Bank shall be deemed
      irrevocably and

                                       23

<PAGE>

      unconditionally to have purchased and received from each such other Banks
      (on a pro rata basis, based on such other Banks' respective Percentages,
      as adjusted in accordance with this Section) a portion of such other
      Banks' participation shares under Section 4.13 in all Letters of Credit
      outstanding on such date and related rights, in an aggregate amount equal
      to such Additional Bank's or such Increasing Bank's Percentage of such
      outstanding Letters of Credit. The addition of any Additional Bank or the
      increase of the Revolving Credit Commitment of an Increasing Bank and the
      effects thereof as described in this Section shall occur automatically
      upon satisfaction of the requirements specified in this Section, without
      the necessity for further documentation to be executed by the other Banks.

            (i) Acknowledgments Regarding Obligation to Increase. The Borrower
      acknowledges that (i) neither the Agent nor any Bank has made any
      representations to the Borrower regarding its intent to agree to any
      increases to the Revolving Credit Commitments described in this Section,
      (ii) no Bank shall have any obligation to increase its Revolving Credit
      Commitment, (iii) any Bank's agreement to one or more increases shall not
      commit such Bank to any additional increases, and (iv) neither the Agent,
      nor any Bank, nor any of their respective Affiliates shall have any
      obligation to find or arrange for any Additional Bank.

            (j) Compensation. The Borrower acknowledges that nothing herein
      shall constitute a waiver of the Borrower's obligation set forth in
      Section 5.6 hereof to provide compensation to the Banks if any
      circumstance arising in connection with any increase in the Revolving
      Credit Commitment results in a LIBOR Advance being paid on a day other
      than the last day of an Interest Period for such LIBOR Advance.

                               Swing Line Advances

      Section 3.1 Swing Line Advances. For the convenience of the parties, the
Agent, solely for its own account, may make any requested Advance under the
Revolving Credit Commitment (which request must be made before 1:00 p.m.
(Houston time) on the Business Day the Advance is to be made and may be
telephonic if confirmed in writing within two Business Days) in the minimum
amount of $500,000 (or a greater integral multiple of $100,000) directly to the
Borrower as a Swing Line Advance without requiring each other Bank to fund its
Percentage thereof on such Business Day. Swing Line Advances are subject to the
following conditions:

            (a) Each Swing Line Advance must occur on a Business Day before the
      Revolving Credit Termination Date;

            (b) The aggregate principal outstanding of all Swing Line Advances
      may not exceed $5,000,000; the aggregate principal amount outstanding of
      all Swing Line Advances, the aggregate principal amount of all Revolving
      Credit Advances, and the Letter of Credit Liabilities may at no time
      exceed the aggregate Revolving Credit Commitments; and no Swing Line
      Advance shall be made which would cause the

                                       24

<PAGE>

      aggregate principal outstanding of Agent's percentage of all Revolving
      Credit Advances (including Swing Line Advances) to exceed the Agent's
      Revolving Credit Commitment;

            (c) Each Swing Line Advance shall be paid in full or Converted by
      the Borrower no later than 10 Business Days after such Swing Line Advance
      is made, and if such Swing Line Advance is not paid within such time, then
      such Swing Line Advance shall be paid in by the funding of an Advance in
      accordance with Section 3.2; and

            (d) Each Swing Line Advance shall accrue interest at the Base Rate
      plus the Applicable Margin for Base Rate Advances and Swing Line Advances.

      Section 3.2 Banks' Funding of Swing Line Advances as Advances. If the
Borrower fails to repay any Swing Line Advance within 10 Business Days after the
making thereof, the Agent shall promptly notify the Banks of such failure and
the unpaid amount, which notice shall, on behalf of the Borrower (and for such
purpose the Borrower hereby irrevocably directs the Agent to act on its behalf),
request each Bank to make, and each Bank hereby agrees to make, an Advance in an
amount equal to such Bank's Percentage of the aggregate amount of such unpaid
Swing Line Advance (each a "Refunded Swing Line Advance"), to repay the Agent.
Each Bank shall make the amount of such Advance available to the Agent in
immediately available funds, not later than 10:00 a.m. Houston time one Business
Day after the date of such notice. The proceeds of such Advance shall be
immediately made available to the Agent for application by the Agent to the
repayment of the Refunded Swing Line Advance. The Borrower irrevocably
authorizes the Agent to charge the Borrower's accounts with the Agent in order
to immediately pay the amount of such Refunded Swing Line Advance to the extent
amounts received from the Banks are not sufficient to repay in full such
Refunded Swing Line Advance (with notice of such charge being provided to the
Borrower, provided that the failure to give such notice shall not affect the
validity of such charge). All such Refunded Swing Line Advances shall be subject
to all provisions of this Agreement concerning Advances, except that such
Advances shall be made without regard to satisfaction of the conditions
precedent to Advances (including the existence of a Default or Event of
Default). If prior to the time an Advance would otherwise have been made
pursuant to this paragraph, Advances may not be made as contemplated by this
paragraph, each Bank shall irrevocably and unconditionally purchase and receive
from Agent a ratable participation in such Swing Line Advance and shall make
available to Agent in immediately available funds its Percentage of such unpaid
amount, together with interest from the date when its payment was due to, but
not including, the date of payment. If a Bank does not promptly pay its amount
upon Agent's demand, and until such Bank makes the required payment, Agent is
deemed to continue to have outstanding a Swing Line Advance in the amount of
such Bank's unpaid obligation. The Borrower shall make each payment of all or
any part of any Swing Line Advance to Agent for the ratable benefit of Agent and
those Banks who have funded their participations in Swing Line Advances under
this section (but all interest accruing on Swing Line Advances before the
funding date of any Advance to repay such Swing Line Advance or any
participation is payable solely to Agent for its own account).

      Section 3.3 The Swing Line Note. The obligation of the Borrower to repay
the Swing Line Advances and interest thereon shall be evidenced by the Swing
Line Note in the principal amount of $5,000,000.

                 Borrowing Procedure: Payments; Facilities Fees;
       Matters Related to Letters of Credit; Matters Related to Advances;
                      Designation of Additional Guarantors

      Section 4.1 Borrowing Procedure. The Borrower shall give the Agent notice
by means of an Advance Request Form of each requested Revolving Credit Advance
(other than Swing Line Advances) at least one Business Day before the requested
date of a Base Rate Advance, and at least three (3) days before the requested
date of a LIBOR Advance, specifying: (a) the requested date of such Revolving
Credit Advance (which shall be a Business Day), (b) the amount of such Revolving
Credit Advance, (c) the Type of the Revolving Credit Advance, and (d) in the
case of a LIBOR Advance, the duration of the Interest Period for such Revolving
Credit Advance. The Agent at its option may accept telephonic requests for
Revolving Credit Advances, provided that such acceptance shall not constitute a
waiver of the Agent's right to delivery of the appropriate Advance Request Form
in connection with subsequent advances. Any telephonic request for an Revolving
Credit Advance by the Borrower shall be promptly continued by submission of a
properly completed Advance Request Form to the Agent. Each Base Rate Advance
shall be in a minimum principal amount of $500,000.00 or a greater integral
multiple of $100,000.00. Each LIBOR Advance shall be in a minimum principal
amount of $3,000,000 or a greater integral multiple of $1,000,000. The Agent
shall notify each Bank of the contents of each such notice on the date such
notice is given by the Borrower. Not later than 11:00 A.M. Houston, Texas time
on the date specified for each Revolving Credit Advance hereunder, each Bank
will make available to the Agent at the Principal Office in immediately
available funds, for the account of the Borrower, its Percentage of each
Revolving Credit Advance. After the Agent's receipt of such funds and subject to
the other terms and conditions of this Agreement, the Agent will make each
Revolving Credit Advance available to the Borrower by depositing the same, in
immediately available funds, in an account of the Borrower (designated by the
Borrower) maintained with the Agent at the Agent's Principal Office. All notices
under this Section shall be irrevocable and shall be given not later than 11:00
A.M. Houston, Texas, time on the day which is not less than the number of
Business Days specified above for such notice.

      Section 4.2 Method of Payment. All payments of principal, interest, and
other amounts to be made by the Borrower under this Agreement and the other Loan
Documents shall be made to the Agent at its Principal Office for the account of
each Bank's Principal Office in Dollars and in immediately available funds,
without setoff, deduction, or counterclaim, not later than 11:00 A.M., Houston,
Texas 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). The Borrower shall, at the time of making each such
payment, specify to the Agent the sums payable by the Borrower under this
Agreement and the other Loan Documents to which such payment is to be applied
(and in the event that the Borrower fails to so specify, or if an Event of
Default has occurred and is continuing, the Agent may apply such payment to the
Obligations in such order and manner as it may elect in its sole discretion,
subject to Section 4.5 hereof). Each payment received by the Agent under this
Agreement or any other Loan Document for the account of a Bank shall be paid
promptly to such Bank, in immediately available funds, for the account of such
Bank's Principal Office.

                                       26

<PAGE>

Whenever any payment under this Agreement or any other Loan Document shall be
stated to be due on a day that is not a Business Day, such payment may be made
on the next succeeding Business Day, and such extension of time shall in such
case be included in the computation of the payment of interest and commitment
fee, as the case may be.

      Section 4.3 Voluntary Prepayment. The Borrower may prepay the Base Rate
Advances in whole at any time or from time to time in part without premium or
penalty upon not less than one Business Day's prior notice to the Agent (which
shall promptly notify the Banks), which notice shall specify the prepayment date
(which shall be a Business Day) and the amount of the prepayment (which shall be
at least $3,000,000 or any whole multiple of $1,000,000 or, if less, the
remaining aggregate principal balance outstanding on the Revolving Credit Notes)
and shall be irrevocable and effective only upon receipt by the Agent, provided
that interest on the principal prepaid, accrued to the prepayment date, shall be
paid on the prepayment date. The Borrower may prepay LIBOR Advances on the same
conditions as for Base Rate Loans (except that prior notice to the Agent shall
be not less than three Business Days for LIBOR Advances) and in addition such
prepayments of LIBOR Advances shall not relieve the Borrower of its obligations
under Section 5.2 or 5.6 hereof.

      Section 4.4 Mandatory Prepayment.

            (a) If at any time the amount equal to the sum of (i) the aggregate
      principal amount of all Revolving Credit Advances, plus (ii) the Letter of
      Credit Liabilities, plus (iii) the aggregate principal amount outstanding
      of all Swing Line Advances exceeds the aggregate Revolving Credit
      Commitments, the Borrower shall promptly prepay the outstanding Revolving
      Credit Advances by the amount of the excess or, if no Revolving Credit
      Advances are outstanding, the Borrower shall immediately pledge to the
      Agent cash or Cash Equivalent Investments in an amount equal to the excess
      as cash collateral for the outstanding Letter of Credit Liabilities.

            (b) Promptly upon receipt of the Net Cash Proceeds from any Asset
      Sale or sale/leaseback transaction with respect to the Borrower's or its
      Subsidiaries' motor vehicles, or receipt of any insurance proceeds with
      respect to properties or assets of the Borrower or any of its
      Subsidiaries, the Borrower shall prepay Advances and permanently reduce
      the Revolving Credit Commitment in accordance with Section 4.4(d) in a
      principal amount equal to 100% of the amount by which aggregate Net Cash
      Proceeds received from such Asset Sales or insurance proceeds during any
      twelve month period exceeds five percent (5.00%) of the Borrower's
      Consolidated Net Worth, and 100% of the amount of Net Cash Proceeds
      received from any such sale/leaseback transaction.

            (c) Except as expressly set forth in this Section 4.4(c), if the
      Borrower or any of its Subsidiaries receives Net Cash Proceeds from the
      issuance of Capital Stock to any Person, and if at such time, the Leverage
      Ratio equals or exceeds 3.50 to 1.00 (based on the most recent financial
      information in Agent's possession at the time of such determination), the
      Borrower shall prepay Advances in accordance with Section 4.4(d) in a
      principal amount equal to 50% of the amount by which aggregate Net Cash
      Proceeds received from such issuances during any twelve month period
      exceeds $2,000,000.

                                       27
<PAGE>

      Notwithstanding the foregoing, the prepayment described above shall not be
      required in connection with (i) an issuance of Capital Stock to First
      Reserve, and (ii) an issuance of Capital Stock made by April 30, 2006 to
      any other Person who has made material investments in, or otherwise has
      long-term experience in managing companies in, the Borrower's industry so
      long as the aggregate Net Cash Proceeds received from such issuances
      pursuant to clause (ii) of this sentence does not exceed $20,000,000;
      provided that, if the aggregate Net Cash Proceeds received from such
      issuances pursuant to clause (ii) of this sentence does exceed
      $20,000,000, the Borrower shall prepay Advances in accordance with Section
      4.4(d) in a principal amount equal to 50% of the amount of such excess.

            (d) Any prepayment made under Sections 4.4(a), (b), and (c) shall
      (i) include accrued interest to the date of such prepayment on the
      principal amount prepaid, (ii) not be subject to (A) any minimum payment
      provisions contained in this Agreement or (B) the requirement set forth in
      Section 5.6 hereof to provide compensation to the Banks if such prepayment
      results in a LIBOR Advance being paid on a day other than the last day of
      an Interest Period for such LIBOR Advance, and (iii) be applied first, to
      repay outstanding Revolving Credit Advances, with a corresponding
      permanent reduction in the Revolving Credit Commitment (other than in
      respect of prepayments under Section 4.4(a) above), and second, at any
      time there are no Advances outstanding under the Revolving Credit
      Commitment, to provide cash collateral for the outstanding Letter of
      Credit Liabilities, provided that, in any event there shall be a permanent
      reduction in the Revolving Credit Commitment in an amount equal to the
      applicable amount of Net Cash Proceeds from the applicable transaction
      which, but for the principal amount of Advances outstanding on the date of
      receipt thereof, would be required to prepay Advances under this Section.

      Section 4.5 Pro Rata Treatment. Except to the extent otherwise provided
herein: (a) each Advance shall be made by the Banks pro rata in accordance with
their respective Percentages, (b) each payment of fees under Section 2.6 and
letter of credit fees under Section 4.12 shall be made for the account of the
Banks pro rata in accordance with their respective Percentages, (c) each
termination or reduction of the Revolving Credit Commitments under Section 2.7
shall be applied to the Revolving Credit Commitments pro rata according to the
respective unused Revolving Credit Commitments, (d) each Letter of Credit shall
be deemed participated in by the Banks, pro rata in accordance with their
respective Percentages; and (e) each payment and prepayment of principal of or
interest on the Advances by the Borrower shall be made to the Agent for the
account of the Banks pro rata in accordance with the respective unpaid principal
amounts of the Advances or the Advances held by such Banks.

      Section 4.6 Non-Receipt of Funds by the Agent. Unless the Agent shall have
been notified by a Bank or the Borrower (the "Payor") prior to the date on which
such Bank is to make payment to the Agent of the proceeds of an Advance to be
made or participated in as applicable, by it hereunder or the Borrower is to
make a payment to the Agent for the account of one or more of the Banks, 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 the Agent, the 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

                                       28

<PAGE>

thereof available to the intended recipient on such date and, if the Payor has
not in fact made the Required Payment to the Agent, the recipient of such
payment shall, on demand, pay to the Agent the amount made available to it
together with interest thereon in respect of the period commencing on the date
such amount was so made available by the Agent until the date the Agent recovers
such amount at a rate per annum equal to the Federal Funds Rate for such period.

      Section 4.7 Withholding Tax Exemption. Each Bank that is not incorporated
under the laws of the United States of America or a state thereof agrees that it
will deliver to the Borrower and the Agent two duly completed copies of Form
W-8BEN or W-8ECI, certifying in either case that such Bank is entitled to
receive payments from the Borrower under any Loan Document without deduction or
withholding of any United States federal income taxes. Each Bank which so
delivers a Form W-8BEN or W-8ECI further undertakes to deliver to the Borrower
and the Agent two additional copies of such form (or a successor form) on or
before the date such form expires or becomes obsolete or after the occurrence of
any event requiring a change in the most recent form so delivered by it, and
such amendments thereto or extensions or renewals thereof as may be reasonably
requested by the Borrower or the Agent, in each case certifying that such Bank
is entitled to receive payments from the Borrower under any Loan Document
without deduction or withholding of any United States federal income taxes,
unless an event (including without limitation any change in treaty, law or
regulation) has occurred prior to the date on which any such delivery would
otherwise be required which renders all such forms inapplicable or which would
prevent such Bank from duly completing and delivering any such form with respect
to it and such Bank advises the Borrower and the Agent that it is not capable of
receiving such payments without any deduction or withholding of United States
federal income tax. Notwithstanding any provisions of this agreement to the
contrary, the Borrower shall make payments net of, and after deductions for,
taxes and shall not be required to increase any such amount payable to any
non-U.S. Bank that fails to comply with this Section.

      Section 4.8 Computation of Interest. Interest on the LIBOR Advances and
all other amounts payable by the Borrower hereunder shall be computed on the
basis of a year of 360 days and the actual number of days elapsed (including the
first day but excluding the last day) unless such calculation would result in a
usurious rate, in which case interest shall be calculated on the basis of a year
of 365 or 366 days, as the case may be. Interest on the Base Rate Advances shall
be computed on the basis of a year of 365 or 366 days, as the case may be.

      Section 4.9 Conversions and Continuation. The Borrower shall have the
right from time to time to Convert all or part of an Advance of one Type into an
Advance of another Type or to Continue LIBOR Advances of one Type as Advances of
the same Type by giving the Agent written notice at least one (l) Business Day
before Conversion into a Base Rate Advance, and at least three (3) Business Days
before Conversion into or Continuation of a LIBOR Advance, specifying: (a) the
Conversion or Continuation date, (b) the amount of the Advance to be Converted
or Continued, (c) in the case of Conversions, the Type of Advance to be
Converted into, and (d) in the case of a Continuation of or Conversion into a
LIBOR Advance, the duration of the Interest Period applicable thereto; provided
that (i) LIBOR Advances may only be Converted on the last day of the applicable
Interest Period, and (ii) except for Conversions into Base Rate Advances, no
Conversions shall be made while a Default or an Event of Default has occurred
and is continuing. All notices under this Section shall be irrevocable and shall
be given not later than 11:00 A.M. Houston, Texas time on the day which is not
less than the number of

                                       29

<PAGE>

Business Days specified above for such notice. The Agent shall promptly notify
the Banks of each such notice it receives. If the Borrower shall fail to give
the Agent the notice as specified above for Continuation or Conversion of a
LIBOR Advance prior to the end of the Interest Period with respect thereto, such
LIBOR Advance shall be Converted automatically into a Base Rate Advance on the
last day of the then current Interest Period for such LIBOR Advance.

      Section 4.10 Letter of Credit Procedure. Each Letter of Credit shall be
issued upon receipt by the Issuing Bank of a written request of the Borrower (a
"Credit Request"), together with a duly executed Letter of Credit Agreement, not
later than 11:00 A.M. (Houston, Texas time), three Business Days prior to the
date set for the issuance of such Letter of Credit. Each Credit Request shall
contain or specify, among other things:

            (a) the proposed date of the issuance of the Letter of Credit, which
      shall be a Business Day;

            (b) the stated amount of the Letter of Credit;

            (c) the date of expiration of the Letter of Credit;

            (d) the name and address of the beneficiary of the Letter of Credit;

            (e) the documents to be presented by the beneficiary of the Letter
      of Credit in case of any drawing thereunder;

            (f) the full text of any certificate to be presented by the
      beneficiary in case of any drawing thereunder;

            (g) the purpose of the Letter of Credit; and

            (h) the aggregate amount of Letter of Credit Liabilities (including
      the requested Letter of Credit) to be existing on the date of issuance of
      such requested Letter of Credit.

      Section 4.11 Amendments to Letters of Credit. Any request for amendment to
or extension of the expiry date of any previously issued Letter of Credit shall
be submitted pursuant to a Credit Request by the Borrower to the Issuing Bank
not later than three Business Days prior to the date of the proposed amendment
or extension. The Issuing Bank shall not amend or extend the expiry date of any
Letter of Credit if the issuance of a new Letter of Credit having the same terms
and conditions as such Letter of Credit as so amended or extended would be
prohibited by any provision of this Agreement.

      Section 4.12 Letter of Credit Fees. The Borrower agrees in all instances,
to pay (a) to the Agent a non-refundable letter of credit fee, due and payable
quarterly in arrears on each Quarterly Fee Payment Date and on the Revolving
Credit Termination Date, for the account of the Banks, which fee shall be equal
to the Applicable Margin for LIBOR Advances on the date of payment multiplied by
the Dollar equivalent (at the applicable Exchange Rate) of the face amount of
each Letter of Credit (with a $600 minimum letter of credit fee per Letter of
Credit issued), and based on a year of 360 days, and (b) to the Issuing Bank a
fronting fee, due and

                                       30

<PAGE>

payable on the date of issuance of any Letter of Credit, for the sole account of
the Issuing Bank, which fee shall be equal to 0.125% of the face amount of each
such Letter of Credit (with a $600 minimum fronting fee per Letter of Credit
issued). Additionally, the Borrower agrees to pay the Issuing Bank, on a demand
basis, all other fees (including without limitation amendment, transfer, or
negotiation fees) due and payable in accordance with the Issuing Bank's then
current fee policy, which fee policy has previously been provided to the
Borrower.

      Section 4.13 Participation by Banks. By the issuance of any Letter of
Credit and without any further action on the part of the Issuing Bank or any of
the Banks in respect thereof, the Issuing Bank hereby grants to each Bank and
each Bank hereby agrees to acquire from the Issuing Bank a participation in each
such Letter of Credit and the related Letter of Credit Liabilities, effective
upon the issuance thereof without recourse or warranty, equal to such Bank's
Percentage of such Letter of Credit and Letter of Credit Liabilities. The
Issuing Bank shall provide a copy of each Letter of Credit to each other Bank
promptly after issuance. This agreement to grant and acquire participations is
an agreement between the Issuing Bank and the Banks, and neither the Borrower
nor any beneficiary of a Letter of Credit or Bank Guaranty shall be entitled to
rely thereon. The Borrower agrees that each Bank purchasing a participation from
the Issuing Bank pursuant to this Section 4.13 may exercise all its rights to
payment against the Borrower including the right of setoff, with respect to such
participation as fully as if such Bank were the direct creditor of the Borrower
in the amount of such participation.

      Section 4.14 Obligations Absolute. The obligations of the Borrower and the
Guarantors under this Agreement and the other Loan Documents (including without
limitation the obligation of the Borrower to reimburse the Issuing Bank for
draws under any Letter of Credit) shall be joint and several, absolute,
unconditional, and irrevocable, and shall be performed strictly in accordance
with the terms of this Agreement and the other Loan Documents under all
circumstances whatsoever, including without limitation the following
circumstances (provided that nothing in this Agreement constitutes a waiver of
the Borrower's rights to assert any claim or defense based upon the gross
negligence or willful misconduct of any Bank):

            (a) Any lack of validity or enforceability of any Letter of Credit
      or any other Loan Document;

            (b) Any amendment or waiver of or any consent to departure from any
      Loan Document;

            (c) The existence of any claim, set-off, counterclaim, defense or
      other rights which the Borrower, any Obligated Party, or any other Person
      may have at any time against any beneficiary of any Letter of Credit, the
      Issuing Bank, or any other Person, whether in connection with this
      Agreement or any other Loan Document or any unrelated transaction except
      for the Agent's, Issuing Bank's, or any Bank's gross negligence or willful
      misconduct;

            (d) The occurrence of any Default or Event of Default; or

            (e) Any statement, draft, or other document presented under any
      Letter of Credit proving to be forged, fraudulent, invalid, or
      insufficient in any respect or any

                                       31

<PAGE>

      statement therein being untrue or inaccurate in any respect whatsoever
      except for the Agent's, Issuing Bank's, or any Bank's gross negligence or
      willful misconduct.

      Section 4.15 Limitation of Liability. The Borrower assumes all risks of
the acts or omissions of any beneficiary of any Letter of Credit with respect to
its use of such Letter of Credit. Neither the Issuing Bank, the Agent, any Bank
nor any of their officers or directors shall have any responsibility or
liability to the Borrower or any other Person for: (a) errors, omissions,
interruptions, or delays in transmission or delivery of any messages, or (b) the
validity, sufficiency, or genuineness of any draft or other document, or any
endorsement(s) thereon, even if any such draft, document or endorsement should
in fact prove to be in any and all respects invalid, insufficient, fraudulent,
or forged or any statement therein is untrue or inaccurate in any respect,
provided that in each case such actions taken or omitted by the Issuing Bank,
the Agent or any Bank are done or omitted in the absence of gross negligence or
willful misconduct. The Issuing Bank 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.

      Section 4.16 Letter of Credit Agreements. Certain additional provisions
regarding the obligations, liabilities, rights, remedies and agreements of the
Borrower and the Issuing Bank relative to the Letters of Credit are set out in
the Letter of Credit Agreements.

      Section 4.17 Replacement of the Issuing Bank. The Borrower may, with the
approval of the Required Banks, appoint a successor Issuing Bank hereunder upon
the condition precedent that such successor Issuing Bank shall become a party to
this Agreement and expressly agree to be bound by the terms and conditions
contained in this Agreement pertaining to the Issuing Bank. Upon the appointment
of a successor Issuing Bank, the Issuing Bank replaced by such successor Issuing
Bank shall cease to issue Letters of Credit but shall continue to carry out its
obligations hereunder and shall continue to have the benefit of this Agreement
and the other Loan Documents with respect to the outstanding Letters of Credit
issued by it until all such Letters of Credit have expired and any drawings
thereunder have been reimbursed in full.

      Section 4.18 No Advances. Neither the Agent nor any Bank shall have any
obligation to make any Advance, if a Default or an Event of Default has occurred
and is continuing.

      Section 4.19 Designation of Additional Guarantors; Revocation of
Designation.

            (a) The Borrower may designate any Domestic Subsidiary which is not
      a Guarantor to be a Domestic Guarantor by delivering to the Agent notice
      that such Domestic Subsidiary is to be a Domestic Guarantor and causing
      such Domestic Subsidiary to execute and deliver to Agent a Guaranty
      Supplement in substantially the form of Exhibit A to the Guaranty
      Agreement-Domestic, a Security Agreement Supplement in substantially the
      form of Exhibit G to the Pledge and Security Agreement, and any applicable
      Mortgage. Any such Domestic Subsidiary shall be deemed a Domestic
      Guarantor five Business Days following the date on which such Domestic
      Subsidiary delivers the documents described above to the Agent.

            (b) The Borrower may designate any Foreign Subsidiary which is not a
      Guarantor to be a Foreign Guarantor by delivering to the Agent notice that
      such Foreign

                                       32

<PAGE>

      Subsidiary is to be a Foreign Guarantor and causing such Foreign
      Subsidiary to execute and deliver to Agent a Guaranty Agreement-Foreign
      and a Pledge and Security Agreement. Any such Foreign Subsidiary shall be
      deemed a Foreign Guarantor five Business Days following the date on which
      such Foreign Subsidiary delivers the documents described above.

            (c) The Borrower may determine that any Subsidiary which has been
      designated to be a Guarantor (other than those which own real property and
      other fixed assets constituting Collateral) shall cease to be a Guarantor
      by delivering to the Agent (i) evidence satisfactory to the Agent that
      such Guarantor is not a Material Subsidiary, and (ii) notice that such
      Guarantor is no longer to be a Guarantor. Five Business Days following the
      date on which the Borrower delivers the documents described in the
      preceding sentence to the Agent and pays any applicable prepayment
      required under Section 4.4(a) of this Agreement, any such Guarantor shall
      cease to be a Guarantor and such Person's Guaranty Agreement, Security
      Agreement and Mortgages shall be null and void and the Agent shall
      promptly deliver such appropriate lien release documents and return any
      applicable Guaranty Agreement, as requested in writing by the Borrower.

                                   ARTICLE V

                         Yield Protection and Illegality

      Section 5.1 Capital Adequacy. If after the date hereof, any adoption or
implementation of any applicable law, rule, or regulation regarding capital
adequacy (including, without limitation, any law, rule, or regulation
implementing the Basle Accord) , or any change therein, or any change in the
interpretation or administration thereof by any central bank or other
Governmental Authority charged with the interpretation or administration
thereof, or compliance by such Bank (or its parent) with any guideline, request,
or directive regarding capital adequacy (whether or not having the force of law)
of any such central bank or other Governmental Authority (including, without
limitation, any guideline or other requirement implementing the Basle Accord),
has or would have the effect of reducing the rate of return on such Bank's (or
its parent's) capital as a consequence of its obligations hereunder or the
transactions contemplated hereby to a level below that which such Bank (or its
parent) could have achieved but for such adoption, implementation, change, or
compliance (taking into consideration such Bank's policies with respect to
capital adequacy) by an amount deemed by such Bank to be material, then from
time to time, within ten Business Days after demand by such Bank (with a copy to
the Agent), the Borrower agrees to pay to such Bank (or its parent) such
additional amount or amounts as will compensate such Bank for such reduction.
Any such demand shall be accompanied by a certificate of such Bank claiming
compensation under this Section and setting forth in reasonable detail the
calculation of the additional amount or amounts to be paid to it hereunder shall
be conclusive (absent manifest error), provided that the determination thereof
is made on a reasonable basis. In determining such amount or amounts, such Bank
may use any reasonable averaging and attribution methods.

      Section 5.2 Additional Costs. The Borrower shall pay (without duplication
of amounts owing under other Sections of this Article V) directly to each Bank
from time to time such amounts as such Bank may determine to be necessary to
compensate it for any costs

                                       33

<PAGE>

incurred by such Bank which the Bank determines are attributable to its making
or maintaining of any LIBOR Advances hereunder or its obligation to make any of
such Advances hereunder, or any reduction in any amount receivable by such Bank
hereunder in respect of any such Advances or such obligation (such increases in
costs and reductions in amounts receivable being herein called "Additional
Costs"), resulting from any Regulatory Change which:

            (a) changes the basis of taxation, of any amounts payable to such
      Bank under this Agreement or its Revolving Credit Note or Swing Line Note
      in respect of any of such Advances (other than taxes imposed on the
      overall net income of such Bank or its Applicable Lending Office for any
      of such Advances by the jurisdiction in which such Bank has its principal
      office or such Applicable Lending Office);

            (b) imposes or modifies any reserve, special deposit, minimum
      capital, capital ratio, or similar requirement relating to any extensions
      of credit or other assets of, or any deposits with or other liabilities or
      commitments of, the Bank (including any of such Advances or any deposits
      referred to in the definition of "LIBOR" in Section 1.1); or

            (c) imposes any other condition affecting this Agreement, the
      Revolving Credit Notes, the Swing Line Note or any of such extensions of
      credit or liabilities or commitments.

Each Bank will notify the Borrower of any event occurring after the date of this
Agreement which will entitle such Bank to compensation pursuant to this Section
5.2 as promptly as practicable after it obtains knowledge thereof and determines
to request such compensation, and will designate a different Applicable Lending
Office for the Advances affected by such event if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
sole opinion of such Bank, violate any law, rule, or regulation or be in any way
disadvantageous to such Bank, provided that such Bank shall have no obligation
to so designate an Applicable Lending Office located in the United States of
America. Each Bank will furnish the Borrower with a certificate setting forth in
reasonable detail the basis and the amount of each request of such Bank for
compensation under this Section 5.2, and the Borrower shall not be obligated to
pay under this Section 5.2 prior to receipt of such certificate. If a Bank
requests compensation from the Borrower under this Section 5.2, the Borrower
may, by notice to such Bank and the Agent suspend the obligation of such Bank to
make or Continue making, or Convert Advances into, Advances of the Type with
respect to which such compensation is requested until the Regulatory Change
giving rise to such request ceases to be in effect (in which case the provisions
of Section 5.5 hereof shall be applicable). Determinations and allocations by a
Bank for purposes of this Section 5.2 of the effect of any Regulatory Change on
its costs of maintaining its obligations to make Advances or of making or
maintaining Advances or on amounts receivable by it in respect of Advances, and
of the additional amounts required to compensate such Bank in respect of any
Additional Costs, shall be conclusive absent manifest error, provided that such
determinations and allocations are made on a reasonable basis and in good faith.

      Section 5.3 Limitation on LIBOR Advances. Anything herein to the contrary
notwithstanding, if with respect to any LIBOR Advances for any Interest Period
therefor:

                                       34

<PAGE>

            (a) The Agent determines (which determination shall be conclusive
      absent manifest error) that quotations of interest rates for the relevant
      deposits referred to in the definition of "LIBOR" in Section 1.1 hereto
      are not being provided in the relative amounts or for the relative
      maturities for purposes of determining the rate of interest for such
      Advances as provided in this Agreement; or

            (b) A Bank determines (which determination shall be conclusive
      absent manifest error) that the relevant rates of interest referred to in
      the definition of "LIBOR" in Section 1.1 hereto on the basis of which the
      rate of interest for such Advances for such Interest Period is to be
      determined do not accurately reflect the cost to such Bank of making or
      maintaining such Advances for such Interest Period; then such Bank shall
      give the Borrower prompt notice thereof and the relevant amounts or
      periods, and so long as such condition remains in effect, such Bank shall
      be under no obligation to make additional LIBOR Advances or to Convert
      Base Rate Advances into LIBOR Advances and the Borrower shall, on the last
      day(s) of the then current Interest Period(s) for, the outstanding LIBOR
      Advances, either prepay such Advances or Convert such Advances into Base
      Rate Advances in accordance with the terms of this Agreement.

      Section 5.4 Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for a Bank or its Applicable
Lending Office to (a) honor its obligation to make LIBOR Advances hereunder or
(b) maintain LIBOR Advances hereunder, then such Bank shall promptly notify the
Borrower thereof and such Bank's obligation to make or maintain LIBOR Advances
and to Convert Base Rate Advances into LIBOR Advances hereunder shall be
suspended until such time as such Bank may again make and maintain LIBOR
Advances (in which case the provisions of Section 5.5 hereof shall be
applicable).

      Section 5.5 Treatment of Certain LIBOR Advances. If the LIBOR Advances of
a Bank are to be Converted pursuant to Section 5.2, 5.3 or 5.4 hereof, such
Bank's LIBOR Advances shall be automatically Converted into Base Rate Advances
on the last day(s)of the then current Interest Period(s) for the LIBOR Advances
(or, in the case of a Conversion required by Section 5.4 hereof, on such earlier
date as such Bank may specify to the Borrower, such earlier date to be not
earlier than the date the Bank gives notice thereof to the Borrower) and, unless
and until such Bank gives notice as provided below that the circumstances
specified in Section 5.2, 5.3 or 5.4 hereof which gave rise to such Conversion
no longer exist:

            (a) To the extent that the Bank's LIBOR Advances have been so
      Converted, all payments and prepayments of principal which would otherwise
      be applied to such Bank's LIBOR Advances shall be applied instead to its
      Base Rate Advances; and

            (b) All Advances which would otherwise be made or Continued by a
      Bank as LIBOR Advances shall be made as or Converted into Base Rate
      Advances and all Advances of such Bank which would otherwise be Converted
      into LIBOR Advances shall be Converted instead into (or shall remain as)
      Base Rate Advances.

If a Bank gives notice to the Borrower that the circumstances specified in
Section 5.2, 5.3 or 5.4 hereof which gave rise to the Conversion of such Bank's
LIBOR Advances pursuant to this Section 5.5 no longer exist (which such Bank
agrees to do promptly upon such circumstances

                                       35

<PAGE>

ceasing to exist) at a time when any LIBOR Advances are outstanding, the Bank's
Base Rate Advances shall be automatically Converted to LIBOR Advances, on the
first day(s) of the next succeeding Interest Period(s) for such outstanding
LIBOR Advances to the extent necessary so that, after giving effect thereto, all
Advances held by the Bank holding LIBOR Advances and by such Banks are held pro
rata (as to principal amounts, Types, and Interest Periods) in accordance with
their respective Percentages. In the event any Bank invokes Section 5.2, 5.3 or
5.4 or Borrower becomes obligated to pay any additional amounts to any Bank
pursuant such Sections, then, unless such Bank has removed or cured the
conditions actuating such Sections, the Borrower may designate a substitute
lender which is an Eligible Assignee (such lender referred to in this Agreement
as a "Replacement Bank") to purchase such Bank 's rights and obligations with
respect to its Percentage of the Revolving Credit Commitments. Any such purchase
shall have a purchase price equal to the outstanding principal amounts payable
to the Bank with respect to all Advances outstanding under this Agreement on the
date of purchase, plus any accrued and unpaid interest, fees and charges
(including breakage charges, if any, up to such date) in respect of such Bank's
Percentage of the Revolving Credit Commitments, and on other terms reasonably
satisfactory to the Agent. Upon such purchase by the Replacement Bank and
payment of all other amounts owing to the Bank being replaced, such exiting Bank
shall no longer be a party to this Agreement or any rights or obligations under
this Agreement and the Replacement Bank shall succeed to the rights and
obligations of the exiting Bank with respect to the exiting Bank's Percentage of
the Revolving Credit Commitments.

      Section 5.6 Compensation. The Borrower shall pay (without duplication of
amounts owing under other Sections of this Article V) to the Banks, upon the
request of any Bank, such amount or amounts as shall be sufficient (in the
reasonable opinion of the Agent) to compensate the Banks for any actual loss,
cost, or expense incurred by them as a result of:

            (a) Any payment, prepayment or Conversion of a LIBOR Advance for any
      reason (including, without limitation, the acceleration of the outstanding
      Advances pursuant to Section 12.2 or any payment pursuant to Section 5.5)
      on a date other than the last day of an Interest Period for such Advance;
      or

            (b) Any failure by the Borrower for any reason (including, without
      limitation, the failure of any conditions precedent specified in Article
      VII to be satisfied) to borrow, Convert, or prepay a LIBOR Advance on the
      date for such borrowing, Conversion, or prepayment, specified in the
      relevant notice of borrowing, prepayment, or Conversion under this
      Agreement.

The Agent shall furnish the Borrower with a certificate setting forth in
reasonable detail the basis and amount of each request for compensation under
this Section 5.6, and the Borrower shall not be obligated to pay under this
Section 5.6 prior to receipt of such certificate.

accelerate, notice of intent to demand, protest, or other formalities of any
kind, all of which are hereby expressly waived by the Borrower; provided,
however, that upon the occurrence of an Event of Default under Section 12.1(d)
or Section 12.1(e), the Revolving Credit Commitments shall automatically
terminate, and the Obligations shall become immediately due and payable without
notice, demand, presentment, notice of dishonor, notice of acceleration, notice
of intent to accelerate, notice of intent to demand, protest, or other
formalities of any kind, all of which are hereby expressly waived by the
Borrower. Except as otherwise expressly set forth herein, if any Event of
Default shall occur and be continuing, the Agent may exercise all rights and
remedies available to it in law or in equity, under the Loan Documents, or
otherwise.

      Section 12.3 Letter of Credit. If any Event of Default shall occur and be
continuing, the Borrower shall, if requested by the Agent, immediately deposit
with and pledge to the Agent cash or Cash Equivalent Investments in an amount
equal to one hundred ten percent (110%) of the outstanding Letter of Credit
Liabilities.

      Section 12.4 Performance by the Agent. If the Borrower shall fail to
perform any covenant or agreement contained in any of the Loan Documents, the
Agent may, at the direction of the Required Banks, perform or attempt to perform
such covenant or agreement on behalf of the Borrower. In such event, the
Borrower shall, at the request of the Agent, promptly pay any amount expended by
the Agent or the Banks in connection with such performance or attempted
performance to the Agent, together with interest thereon at the Default Rate
from and including the date of such expenditure to but excluding the date such
expenditure is paid in full. Notwithstanding the foregoing, it is expressly
agreed that neither the Agent, the Issuing Bank nor any Bank shall have any
liability or responsibility for the performance of any obligation of the
Borrower under this Agreement or any other Loan Document except for the Agent's
gross negligence or willful misconduct.

                                  ARTICLE XIII

      Note and to distribute to each Bank, the Issuing Bank and the Agent, or
      any or some of them its share of all payments so received as provided in
      this Agreement;

            (b) To receive all documents and items to be furnished under the
      Loan Documents;

13.1(g) hereof or anything else to the contrary, the Agent shall not, without
the prior written consent of each Lender (i) appoint one or more members of the
Board of Directors (or similar governing body) of the Borrower or any of its
Affiliates, or (ii) exercise any rights or remedies with respect to any Capital
Stock pledged to secure any or all of the Obligations; provided, however, if any
Lender does not, within thirty (30) days after such Lender's receipt of a
written request from the Agent for a consent to one or more of the actions
described in clause (i) or (ii) of this sentence, respond to any such written
request, such Lender shall, for the purposes of this sentence, be deemed to have

                                       62
<PAGE>

      Neither the Agent nor any of its Affiliates, officers, directors,
employees, attorneys, or agents shall be liable for any action taken or omitted
to be taken by any of them hereunder or otherwise in connection with this
Agreement or any of the other Loan Documents except for its or their own gross
negligence or willful misconduct. Without limiting the generality of the

of them under, this Agreement or any other Loan Document or for the value,
validity, effectiveness, enforceability, or sufficiency of this Agreement or any
other Loan Document or any other document referred to or provided for herein or
therein or for any failure by any Person to perform any of its obligations
hereunder or thereunder; (v) may consult with legal counsel (including counsel
for the Borrower), independent public accountants, and other experts selected by
it and shall not be liable for any action taken or omitted to be taken in good
faith by it in accordance with the advice of such counsel, accountants, or
experts; and (vi) shall incur no liability under or in respect of any Loan
Document by acting upon any notice, consent, certificate, or other instrument or
writing believed by it to be genuine and signed or sent by the proper party or
parties. As to any matters not expressly provided for by this Agreement, the
Agent shall in all cases be fully protected in acting, or in refraining from
acting, hereunder in accordance with instructions signed by the Required Banks,
and such instructions of the Required Banks and any action taken or failure to
act pursuant thereto shall be binding on all of the Banks; provided, however,
that the Agent shall not be required to take any action which exposes the Agent
to personal liability or which is contrary to this Agreement or any other Loan
Document or applicable law.

      Section 13.2 Rights of Agent as a Bank. With respect to its commitment to
lend hereunder, the Advances made by it and the Revolving Credit Note and Swing
Line Note issued to it, the Agent in its capacity as a Bank hereunder shall have
the same rights and powers hereunder as any other Bank and may exercise the same
as though it were not acting as the Agent or the Issuing Bank and the term
"Bank" or "Banks" shall, unless the context otherwise indicates, include the
Agent in its individual capacity. The Agent and its Affiliates may (without
having to account therefor to any Banks or the Issuing Bank) accept deposits
from, lend money to, act as trustee under indentures of, provide merchant
banking services to, and generally engage in any kind of business with the
Borrower, any of its Subsidiaries, any other Obligated Party, and any other
Person who may do business with or own securities of the Borrower, any
Subsidiary, or any other Obligated Party, all as if it were not acting as the
Agent and without any duty to account therefor to the Banks or the Issuing Bank.

      Section 13.3 Sharing of Payments, Etc. If any Bank shall obtain any
payment of any principal of or interest on any Advance made by it under this
Agreement or payment of any other obligation under the Loan Documents then owed
by the Borrower or any other Obligated Party

                                       63
<PAGE>

to such Bank, whether voluntary, involuntary, through the exercise of any right
of setoff, banker's lien, counterclaim or similar right, or otherwise, in excess
of its pro rata share, such Bank shall promptly purchase from the other Banks
participations in the Advances held by them hereunder in such amounts, and make
such other adjustments from time to time as shall be necessary to cause such
purchasing Bank to share the excess payment ratably with each of the other Banks
in accordance with its pro rata portion thereof. To such end, all of the Banks
shall make appropriate adjustments among themselves (by the resale of
participations sold or otherwise) if all or any portion of such excess payment
is thereafter rescinded or must otherwise be restored. The Borrower agrees, to
the fullest extent it may effectively do so under applicable law, that any Bank
so purchasing a participation in the Advances made by the other Banks may
exercise all rights of setoff, banker's lien, counterclaim, or similar rights
with respect to such participation as fully as if such Bank were a direct holder
of Advances to the Borrower in the amount of such participation. Nothing
contained herein shall require any Bank to exercise any such right or shall
affect the right of any Bank to exercise, and retain the benefits of exercising,
any such right with respect to any other indebtedness or obligation of the
Borrower.

      Section 13.4 Indemnification. THE BANKS HEREBY AGREE TO INDEMNIFY THE
AGENT FROM AND HOLD THE AGENT AND THE ISSUING BANK HARMLESS AGAINST (TO THE
EXTENT NOT REIMBURSED UNDER SECTIONS 14.1 AND 14.2, BUT WITHOUT LIMITING THE
OBLIGATIONS OF THE BORROWER UNDER SECTIONS 14.1 AND 14.2), RATABLY IN ACCORDANCE
WITH THEIR RESPECTIVE COMMITMENTS, ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES,
DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, DEFICIENCIES, SUITS, COSTS, EXPENSES
(INCLUDING ATTORNEYS' FEES), AND DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER
WHICH MAY BE IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST THE AGENT OR THE
ISSUING BANK IN ANY WAY RELATING TO OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS
OR ANY ACTION TAKEN OR OMITTED TO BE TAKEN BY THE AGENT OR THE ISSUING BANK
UNDER OR IN RESPECT OF ANY OF THE LOAN DOCUMENTS; PROVIDED, THAT NO BANK SHALL
BE LIABLE FOR ANY PORTION OF THE FOREGOING TO THE EXTENT CAUSED BY THE AGENT'S
OR THE ISSUING BANK'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. WITHOUT LIMITATION
OF THE FOREGOING, IT IS THE EXPRESS INTENTION OF THE BANKS THAT THE AGENT AND
THE ISSUING BANK SHALL BE INDEMNIFIED HEREUNDER FROM AND HELD HARMLESS AGAINST
ALL OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
JUDGMENTS, DEFICIENCIES, SUITS, COSTS, EXPENSES (INCLUDING ATTORNEYS' FEES), AND
DISBURSEMENTS OF ANY KIND OR NATURE DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RESULTING FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE OF THE AGENT OR THE ISSUING
BANK. WITHOUT LIMITING ANY OTHER PROVISION OF THIS SECTION, EACH BANK AGREES TO
REIMBURSE THE AGENT AND THE ISSUING BANK PROMPTLY UPON DEMAND FOR ITS PRO RATA
SHARE (CALCULATED ON THE BASIS OF THE COMMITMENTS) OF ANY AND ALL OUT-OF-POCKET
EXPENSES (INCLUDING ATTORNEYS' FEES) INCURRED BY THE AGENT OR THE ISSUING BANK
IN CONNECTION WITH THE PREPARATION, EXECUTION, DELIVERY, ADMINISTRATION,
MODIFICATION, AMENDMENT OR ENFORCEMENT (WHETHER THROUGH NEGOTIATIONS, LEGAL
PROCEEDINGS, OR OTHERWISE) OF, OR LEGAL ADVICE IN RESPECT OF RIGHTS OR

                                       64
<PAGE>

RESPONSIBILITIES UNDER, THE LOAN DOCUMENTS, TO THE EXTENT THAT THE AGENT OR THE
ISSUING BANK IS NOT REIMBURSED FOR SUCH EXPENSES BY THE BORROWER.

      Section 13.5 Independent Credit Decisions. Each Bank agrees that it has
independently and without reliance on the Agent, the Issuing Bank, or any other
Bank, and based on such documents and information as it has deemed appropriate,
made its own credit analysis of the Borrower and the Obligated Parties and
decision to enter into this Agreement and that it will, independently and
without reliance upon the Agent, the Issuing Bank, or any other Bank, and based
upon 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 Agreement or any of the other Loan Documents. The Agent shall not be
required to keep itself informed as to the performance or observance by the
Borrower or any Obligated Party of this Agreement or any other Loan Document or
to inspect the properties or books of the Borrower or any Obligated Party.
Except for notices, reports and other documents and information expressly
required to be furnished to the Banks by the Agent hereunder or under the other
Loan Documents, the Agent shall not have any duty or responsibility to provide
the Issuing Bank or any Bank with any credit or other financial information
concerning the affairs, financial condition or business of the Borrower or any
Obligated Party (or any of their Affiliates) which may come into the possession
of the Agent or any of its Affiliates.

      Section 13.6 Several Commitments. The commitments to lend and other
obligations of the Banks under this Agreement are several. The default by the
Bank in making an Advance in accordance with its commitment hereunder shall not
relieve the other Banks of their obligations under this Agreement. In the event
of any default by any Bank in making any Advance, each nondefaulting Bank shall
be obligated to make its Advance but shall not be obligated to advance the
amount which the defaulting Bank was required to advance hereunder. In no event
shall any Bank be required to advance an amount or amounts which shall in the
aggregate exceed such Bank's Revolving Credit Commitment. No Bank shall be
responsible for any act or omission of any other Bank.

      Section 13.7 Successor Agent. Subject to the appointment and acceptance of
a successor Agent as provided below, the Agent may resign at any time by giving
notice thereof to the Banks and the Borrower and the Agent may be removed at any
time with or without cause by the Required Banks. Upon any such resignation or
removal, the Required Banks (with the consent of the Borrower, with consent will
not be unreasonably withheld) will have the right to appoint a successor Agent.
If no successor Agent shall have been so appointed by the Required Banks and
shall have accepted such appointment within thirty (30) days after the retiring
Agent's giving notice of resignation or the Required Banks' removal of the
retiring Agent, then the retiring Agent may, on behalf of the Banks, appoint a
successor Agent, which shall be a commercial bank organized under the laws of
the United States of America or any State thereof and having combined capital
and surplus of at least $500,000,000.00. Upon the acceptance of its appointment
as successor Agent, such successor Agent shall thereupon succeed to and become
vested with all rights, powers, privileges, immunities, and duties of the
resigning or removed Agent, and the resigning or removed Agent shall be
discharged from its duties and obligations under this Agreement and the other
Loan Documents. After any Agent's resignation or removal

                                       65
<PAGE>

as Agent, the provisions of this Article XIII shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was the Agent.

                                   ARTICLE XIV

                                  Miscellaneous

      Section 14.1 Expenses. Borrower hereby agrees to pay on demand (a) all

Banks in connection with this Agreement or any other Loan Document, including,
without limitation, all costs, expenses, and other charges incurred in
connection with obtaining audit, or appraisal in respect of the Collateral.

      Section 14.2 Indemnification. THE BORROWER SHALL INDEMNIFY EACH OF THE
AGENT, THE ISSUING BANK, AND THE BANKS AND EACH AFFILIATE THEREOF AND THEIR
RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, ATTORNEYS, AND AGENTS FROM, AND HOLD
EACH OF THEM HARMLESS AGAINST, ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DAMAGES,
PENALTIES, JUDGMENT, DISBURSEMENTS, COSTS, AND EXPENSES (INCLUDING ATTORNEYS'
FEES) TO WHICH ANY OF THEM MAY BECOME SUBJECT WHICH DIRECTLY OR INDIRECTLY ARISE

DOCUMENTS, (D) THE PRESENCE, RELEASE, THREATENED RELEASE, DISPOSAL, REMOVAL, OR

INVESTIGATION, LITIGATION, OR OTHER PROCEEDING, INCLUDING, WITHOUT LIMITATION,
ANY THREATENED INVESTIGATION, LITIGATION, OR OTHER PROCEEDING, RELATING TO ANY
OF THE FOREGOING.

      Section 14.3 Limitation of Liability. Neither the Agent, the Issuing Bank
or the Banks nor any Affiliate, officer, director, employee, attorney, or agent
of the Agent, the Issuing Bank or

                                       66
<PAGE>

the Banks shall have any liability with respect to, and the Borrower hereby
waives, releases, and agrees not to sue any of them upon, any claim for any
special, indirect, incidental, or consequential damages suffered or incurred by
the Borrower in connection with, arising out of, or in any way related to, this
Agreement or any of the other Loan Documents, or any of the transactions
contemplated by this Agreement or any of the other Loan Documents. The Borrower
hereby waives, releases, and agrees not to sue the Agent, the Issuing Bank or
the Banks or any of such Person's Affiliates, officers, directors, employees,
attorneys, or agents for punitive damages in respect of any claim in connection
with, arising out of, or in any way related to, this Agreement or any of the
other Loan Documents, or any of the transactions contemplated by this Agreement
or any of the other Loan Documents. Nothing contained in this Section shall
affect the rights of the Borrower to collect actual damages awarded to them
against any of the Agents, the Issuing Bank, the Banks or any Affiliate of any
of the foregoing Persons.

      Section 14.4 No Duty. All attorneys, accountants, appraisers, and other
professional Persons and consultants retained by any of the Agent, the Issuing
Bank or the Banks shall have the right to act exclusively in the interest of
such Persons and shall have no duty of disclosure, duty of loyalty, duty of

Borrower or any of the Borrower's shareholders or any other Person.

      Section 14.5 Bank Not Fiduciary. The relationship between the Borrower, on
one hand, and the Agent, the Issuing Bank and the Banks, on the other hand, is
solely that of debtor and creditor, and no such Person has any fiduciary or
other special relationship with the Borrower, and no term or condition of any of
the Loan Documents shall be construed so as to deem the relationship between the
Borrower and such Persons to be other than that of debtor and creditor.

      Section 14.6 No Waiver; Cumulative Remedies. No failure on the part of any
of the Agent, the Issuing Bank or the Banks to exercise and no delay in
exercising, and no course of dealing with respect to, any right, power, or
privilege under this Agreement shall operate as a waiver thereof, nor shall any
single or partial exercise of any right, power, or privilege under this
Agreement preclude any other or further exercise thereof or the exercise of any
other right, power or privilege. The rights and remedies provided for in this
Agreement and the other Loan Documents are cumulative and not exclusive of any
rights and remedies provided by law.

      Section 14.7 Successors and Assigns.

            (a) This Agreement shall be binding upon and inure to the benefit of
      the parties hereto and their respective successors and assigns. The
      Borrower may not assign or transfer any of its rights or obligations
      hereunder without the prior written consent of the Agent and all of the
      Banks. Any Bank may sell participations to one or more banks or other
      institutions in or to all or a portion of its rights and obligations under
      this Agreement and the other Loan Documents (including, without
      limitation, all or a portion of its Revolving Credit Commitments and the
      Advances owing to it); provided, however, that (i) such Bank's obligations
      under this Agreement and the other Loan Documents (including, without
      limitation, its Revolving Credit Commitments) shall remain unchanged, (ii)
      such Bank shall remain solely responsible to the Borrower for the
      performance of such obligations, (iii) such Bank shall remain the holder
      of its Revolving Credit Notes for all purposes of this Agreement, and (iv)
      the Borrower shall continue to

                                       67
<PAGE>

      deal solely and directly with such Bank in connection with such Bank's
      rights and obligations under this Agreement and the other Loan Documents.
      Participants have no rights under the Loan Documents except as provided
      below. Subject to the following, each Bank may obtain, on behalf of its
      participants, the benefits of Article V with respect to all participations
      in its part of the Obligations outstanding from time to time, so long as
      Borrower is not obligated to pay any amount in excess of the amount that
      would be due to that Bank under Article V calculated as though no
      participations have been made. No Bank may sell any participating interest
      under which the participant has any rights to approve any amendment,
      modification, or waiver of any Loan Document except as to matters in
      Section 14.9(a), (b) and (c).

            (b) The Borrower and each of the Banks agree that any Bank (the
      "Assigning Bank") may, with the Agent's consent (which consent shall not
      be unreasonably withheld or delayed) and unless an Event of Default has
      occurred, the Borrower's consent, which consent of the Borrower shall not
      be unreasonably withheld or delayed, at any time assign to one or more
      Eligible Assignees all, or a proportionate part of all, of its rights and
      obligations under this Agreement and the other Loan Documents (including,
      without limitation, its Revolving Credit Commitments and Advances) (each
      an "Assignee"); provided, however, that (i) each such assignment shall be
      of a consistent, and not a varying, percentage of all of the Assigning
      Bank's Revolving Credit Commitments, rights and obligations under this
      Agreement and the other Loan Documents, (ii) except in the case of an
      assignment of all of a Bank's rights and obligations under this Agreement
      and the other Loan Documents, the amount of the Revolving Credit
      Commitments of the Assigning Bank being assigned pursuant to each
      assignment (determined as of the date of the Assignment and Acceptance
      with respect to such assignment) shall in no event be less than $5,000,000
      in the aggregate, and (iii) the parties to each such assignment shall
      execute and deliver to the Agent for its acceptance and recording in the
      Register (as defined below), an Assignment and Acceptance, together with
      the Revolving Credit Notes (and the Swing Line Note, if applicable)
      subject to such assignment, and a processing and recordation fee of $5,000
      to be paid by the Assignee. Upon such execution, delivery, acceptance, and
      recording, from and after the effective date specified in each Assignment
      and Acceptance, which effective date shall be at least five Business Days
      after the execution thereof, or, if so specified in such Assignment and
      Acceptance, the date of acceptance thereof by the Agent, (x) the assignee
      thereunder shall be a party hereto as a "Bank" and, to the extent that
      rights and obligations hereunder have been assigned to it pursuant to such
      Assignment and Acceptance, have the rights and obligations of a Bank
      hereunder and under the Loan Documents and (y) the Bank that is an
      assignor thereunder shall, to the extent that rights and obligations
      hereunder have been assigned by it pursuant to such Assignment and
      Acceptance, relinquish its rights and be released from its obligations
      under this Agreement and the other Loan Documents (and, in the case of an
      Assignment and Acceptance covering all or the remaining portion of a
      Bank's rights and obligations under the Loan Documents, such Bank shall
      cease to be a party thereto); provided that the obligations of the
      Borrower under Article V and Section 14.1 and 14.2 shall continue to apply
      to such Bank.

            (c) By executing and delivering an Assignment and Acceptance, the
      Bank that is an assignor thereunder and the assignee thereunder confirm to
      and agree with each

                                       68
<PAGE>

      other and the other parties hereto as follows: (i) other than as provided
      in such Assignment and Acceptance, such Assigning Bank makes no
      representation or warranty and assumes no responsibility with respect to
      any statements, warranties, or representations made in or in connection
      with the Loan Documents or the execution, legality, validity, and
      enforceability, genuineness, sufficiency, or value of the Loan Documents
      or any other instrument or document furnished pursuant thereto; (ii) such
      Assigning Bank makes no representation or warranty and assumes no
      responsibility with respect to the financial condition of the Borrower or
      any Obligated Party or the performance or observance by the Borrower or
      any Obligated Party of its obligations under the Loan Documents; (iii)
      such assignee confirms that it has received a copy of the other Loan
      Documents, together with copies of the current financial statements dated
      a date acceptable to such assignee and such other documents and
      information as it has deemed appropriate to make its own credit analysis
      and decision to enter into such Assignment and Acceptance; (iv) such
      assignee will, independently and without reliance upon the Agent or such
      assignor and based on such documents and information as it shall deem
      appropriate at the time, continue to make its own credit decisions in
      taking or not taking action under this Agreement and the other Loan
      Documents; (v) such assignee confirms that it is an Eligible Assignee;
      (vi) such assignee appoints and authorizes the Agent to take such action
      as agent on its behalf and exercise such powers under the Loan Documents
      as are delegated to the Agent by the terms thereof, together with such
      powers as are reasonably incidental thereto; and (vii) such assignee
      agrees that it will perform in accordance with their terms all of the
      obligations which by the terms of the Loan Documents are required to be
      performed by it as a Bank.

            (d) The Agent shall maintain at its Principal Office a copy of each
      Assignment and Acceptance delivered to and accepted by it and a register
      for the recordation of the names and addresses of the Banks and the
      Revolving Credit Commitments of, and principal amount of the Revolving
      Credit Advances owing to, each Bank from time to time (the "Register").
      The entries in the Register shall be conclusive and binding for all
      purposes, absent manifest error, and the Borrower, the Agent, the Issuing
      Bank and the Banks may treat each Person whose name is recorded in the
      Register as a Bank hereunder for all purposes under the Loan Documents.
      The Register shall be available for inspection by the Borrower, the
      Issuing Bank or any Bank at any reasonable time and from time to time upon
      reasonable prior notice.

            (e) Upon its receipt of an Assignment and Acceptance executed by an
      Assigning Bank and assignee representing that it is an Eligible Assignee,
      together with any Revolving Credit Note (and the Swing Line Note, if
      applicable) subject to such assignment, the Agent shall, if such
      Assignment and Acceptance has been completed and is in the form
      satisfactory to the Agent in its sole discretion, (i) accept such
      Assignment and Acceptance, (ii) record the information contained therein
      in the Register, and (iii) give prompt written notice thereof to the
      Borrower. Within five (5) Business Days after its receipt of such notice,
      the Borrower, at its expense, shall execute and deliver to the Agent in
      exchange for the surrendered Revolving Credit Notes (and Swing Line Note,
      if applicable), new Revolving Credit Notes (and Swing Line Note, if
      applicable) to the order of such Eligible Assignee in an amount equal to
      the Revolving Credit Commitments assumed by it pursuant to such Assignment
      and Acceptance and, if the

                                       69
<PAGE>

      Assigning Bank has retained a portion of its Revolving Credit Commitments,
      new Revolving Credit Notes to the order of the Assigning Bank in an amount
      equal to the Revolving Credit Commitments retained by it hereunder (each
      such promissory note shall constitute a "Revolving Credit Note" for
      purposes of the Loan Documents). Such new Revolving Credit Notes (and
      Swing Line Note, if applicable) shall be in an aggregate principal amount
      of the surrendered Revolving Credit Notes (and Swing Line Note, if
      applicable), shall be dated the last interest payment date prior to the
      effective date of such Assignment and Acceptance, and shall otherwise be
      in substantially the form of the appropriate Revolving Credit Notes (and
      Swing Line Note, if applicable) initially issued pursuant hereto with
      appropriate changes.

            (f) Any Bank may, in connection with any assignment or participation
      or proposed assignment or participation pursuant to this Section, disclose
      to the assignee or participant or proposed assignee or participant, any
      information relating to the Borrower or its Subsidiaries furnished to such
      Bank by or on behalf of the Borrower or its Subsidiaries.

      Section 14.8 Survival. All representations and warranties made in this
Agreement or any other Loan Documents or in any document, statement, or
certificate furnished in connection with this Agreement shall survive the
execution and delivery of this Agreement and the other Loan Documents, and no
investigation by any of the Agent, the Issuing Bank or the Banks or any closing
shall affect the representations and warranties or the right of any such Person
to rely upon them. Without prejudice to the survival of any other obligation of
the Borrower hereunder, the obligations of the Borrower under Article V and
Sections 14.1 and 14.2 shall survive repayment of the Revolving Credit Notes and
the Swing Line Note and termination of the Banks' commitments to lend hereunder.

      Section 14.9 ENTIRE AGREEMENT; AMENDMENTS. THIS AGREEMENT, THE REVOLVING
CREDIT NOTES, THE SWING LINE NOTE AND THE OTHER LOAN DOCUMENTS REFERRED TO
HEREIN EMBODY THE FINAL, ENTIRE AGREEMENT AMONG THE PARTIES HERETO AND SUPERSEDE
ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS, AND UNDERSTANDINGS,
WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF AND MAY NOT BE
CONTRADICTED OR VARIED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OR DISCUSSIONS OF THE PARTIES HERETO. THERE ARE NO ORAL AGREEMENTS
AMONG THE PARTIES HERETO. No amendment, modification or waiver of, or consent
with respect to, any provision of this Agreement, the Revolving Credit Notes, or
the Swing Line Note shall in any event be effective unless the same shall be in
writing and signed and delivered by the Borrower and the Required Banks, and
then any such amendment, modification, waiver or consent shall be effective only
in the specific instance and for the specific purpose for which given. Subject
to Section 2.10, no amendment, modification, waiver or consent shall change the
Percentage of any Bank without the consent of such Bank. No amendment,
modification, waiver or consent shall (a) extend or increase the amount of the
Revolving Credit Commitments, (b) extend the date for payment of any principal
of or interest on the Advances or any fees or other amounts payable hereunder,
(c) reduce the principal amount of any Advances, the rate of interest thereof or
any fees or other amounts payable hereunder,

                                       70
<PAGE>

(d) release a Guaranty Agreement (other than with respect to a Guarantor which
ceases to be a Material Subsidiary as a result of a transaction permitted
hereunder) or all or substantially all of the Collateral, or (e) reduce the
aggregate Percentage required to effect an amendment, modification, waiver or
consent without, in each case, the consent of all Banks. No provisions of
Article XIII or other provision of this Agreement affecting the Agent in its
capacity as such shall be amended, modified or waived without the consent of the
Agent. No provision of this Agreement relating to the rights or duties of an
Issuing Bank in its capacity as such shall be amended, modified or waived
without the consent of such Issuing Bank. If, in connection with any proposed
amendment, waiver or consent (a "Proposed Change"):

      (i) requiring the consent of all Banks, the consent of Required Banks is
obtained, but the consent of other Banks is not obtained (any such Bank whose
consent is not obtained as described in this clause (i) and in clause (ii) below
being referred to as a "Non-Consenting Bank"), or

      (ii) requiring the consent of Required Banks, the consent of Required
Banks is obtained,

then, so long as the Agent is not a Non-Consenting Bank, at the Borrower's
request, the Agent or an Eligible Assignee shall have the right (but not the
obligation) with the Agent's approval, to purchase from the Non-Consenting
Banks' Revolving Credit Commitments for an amount equal to the principal
balances thereof and all accrued interest and fees with respect thereto through
the date of sale pursuant to Assignment and Acceptance(s), without premium or
discount.

      Section 14.10 Maximum Interest Rate. No provision of this Agreement or any
other Loan Document shall require the payment or the collection of interest in
excess of the maximum amount permitted by applicable law. If any excess of
interest in such respect is hereby provided for, or shall be adjudicated to be
so provided, in any Loan Document or otherwise in connection with this loan
transaction, the provisions of this Section shall govern and prevail and neither
the Borrower nor the sureties, guarantors, successors, or assigns of the
Borrower shall be obligated to pay the excess amount of such interest or any
other excess sum paid for the use, forbearance, or detention of sums loaned
pursuant hereto. In the event any of the Agent, the Issuing Bank or the Banks
ever receives, collects, or applies as interest any such sum, such amount which
would be in excess of the maximum amount permitted by applicable law shall be
applied as a payment and reduction of the principal of the indebtedness
evidenced by the Revolving Credit Notes or the Swing Line Note, as applicable;
and, if the principal of the Revolving Credit Notes and the Swing Line Note has
been paid in full, any remaining excess shall forthwith be paid to the Borrower.
In determining whether or not the interest paid or payable exceeds the Maximum
Rate, the Borrower and the Agent, the Issuing Bank and the Banks shall, to the
extent permitted by applicable law, (a) characterize any non-principal payment
as an expense, fee, or premium rather than as interest, (b) exclude voluntary
prepayments and the effects thereof; and (c) amortize, prorate, allocate, and
spread in equal or unequal parts the total amount of interest throughout the
entire contemplated term of the indebtedness evidenced by the Revolving Credit
Notes and the Swing Line Note so that interest for the entire term does not
exceed the Maximum Rate.

shall not be effective until received by the Agent.

      Section 14.12 GOVERNING LAW; VENUE; SERVICE OF PROCESS. THIS AGREEMENT
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
TEXAS AND THE APPLICABLE LAWS OF THE UNITED STATES OF AMERICA. THIS AGREEMENT
HAS BEEN ENTERED INTO IN HARRIS COUNTY, TEXAS, AND IT SHALL BE PERFORMABLE FOR
ALL PURPOSES IN HARRIS COUNTY, TEXAS. SUBJECT TO SECTION 14.19, ANY ACTION OR
PROCEEDING AGAINST THE BORROWER UNDER OR IN CONNECTION WITH ANY OF THE LOAN
DOCUMENTS MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT IN HARRIS COUNTY, TEXAS.
THE BORROWER HEREBY IRREVOCABLY (A) SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF
SUCH COURTS, AND (B) WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE
VENUE OF ANY SUCH ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT OR THAT ANY
SUCH COURT IS AN INCONVENIENT FORUM. THE BORROWER AGREES THAT SERVICE OF PROCESS
UPON IT MAY BE MADE BY CERTIFIED OR REGISTERED MAIL, RETURN RECEIPT REQUESTED,
AT ITS ADDRESS SPECIFIED OR DETERMINED IN ACCORDANCE WITH THE PROVISIONS OF
SECTION 14.11. NOTHING HEREIN OR IN ANY OF THE OTHER LOAN DOCUMENTS SHALL AFFECT
THE RIGHT OF THE AGENT, THE ISSUING BANK OR THE BANKS TO SERVE PROCESS IN ANY
OTHER MANNER PERMITTED BY LAW OR, SUBJECT TO SECTION 14.19, SHALL LIMIT THE
RIGHT OF SUCH PERSONS TO BRING ANY ACTION OR PROCEEDING AGAINST THE BORROWER OR
WITH RESPECT TO ANY OF ITS PROPERTY IN COURTS IN OTHER JURISDICTIONS. SUBJECT TO
SECTION 14.19, ANY ACTION OR PROCEEDING BY THE BORROWER AGAINST ANY OF THE
AGENT, THE ISSUING BANK OR THE BANKS SHALL BE BROUGHT ONLY IN A COURT LOCATED IN
HARRIS COUNTY, TEXAS.

      Section 14.13 Counterparts; Facsimiles. This Agreement may be executed in
one or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument. Facsimiles of
signatures shall be binding and effective as originals.

      Section 14.14 Severability. Any provision of this Agreement by a court of
competent jurisdiction to be invalid or unenforceable shall not impair or
invalidate the remainder of this Agreement and the effect thereof shall be
confined to the provision held to be invalid or illegal.

      Section 14.15 Headings. The headings, captions, and arrangements used in
this Agreement are for convenience only and shall not affect the interpretation
of this Agreement.

      Section 14.16 Non-Application of Chapter 346 of Texas Finance Code. The
provisions of Chapter 346 of the Texas Finance Code are specifically declared by
the parties hereto not to be applicable to this Agreement or any of the other
Loan Documents or to the transactions contemplated hereby.

      Section 14.17 Construction. The Borrower, the Agent, the Issuing Bank and
the Banks acknowledge that each of them has had the benefit of legal counsel of
its own choice and has been afforded an opportunity to review this Agreement and
the other Loan Documents with its legal counsel and that this Agreement and the
other Loan Documents shall be construed as if jointly drafted by the Borrower,
the Agent, the Issuing Bank and the Banks.

      Section 14.18 Independence of Covenants. All covenants hereunder shall be
given independent effect so that if a particular action or condition is not
permitted by any of such covenants, the fact that it would be permitted by an
exception to, or be otherwise within the limitations of, another covenant shall
not avoid the occurrence of a Default if such action is taken or such condition
exists.

      Section 14.19 Waiver of Trial By Jury. To the fullest extent permitted, by
applicable law, EACH OF the Borrower, THE AGENT AND THE BANKS hereby
voluntarily, knowingly, irrevocably and unconditionally waives any right to have
a jury participate in resolving any dispute (whether based upon contract, tort
or otherwise) between or among the Borrower and any other party to this
Agreement arising out of or in any way related to this Agreement, any other Loan
Documents, or any relationship between any other party to this Agreement and the
Borrower. This provision is a material inducement to the Banks to provide the
financing described in this Agreement.

      Section 14.20 Amendment and Restatement; Release. This Agreement amends
and restates in its entirety the Existing Credit Agreement. The execution of
this Agreement and the other Loan Documents executed in connection herewith does
not extinguish the indebtedness outstanding in connection with the Existing
Credit Agreement nor does it constitute a novation with respect to such
indebtedness. THE BORROWER REPRESENTS AND WARRANTS THAT AS OF THE DATE HEREOF
THERE ARE NO CLAIMS OR OFFSETS AGAINST OR DEFENSES OR COUNTERCLAIMS TO ITS OR
ANY OBLIGATED PARTIES' OBLIGATIONS UNDER THE EXISTING CREDIT AGREEMENT, THE
OTHER LOAN DOCUMENTS AND THE DOCUMENTATION RELATING TO THE DEPOSIT AND CASH
MANAGEMENT SERVICES. TO INDUCE THE AGENT, THE ISSUING BANK AND THE BANKS TO
ENTER INTO THIS AGREEMENT, THE BORROWER AND, BY THE EXECUTION OF THE LOAN
DOCUMENTS TO WHICH IT IS A PARTY, EACH GUARANTOR WAIVES ANY AND ALL CLAIMS,
OFFSETS, DEFENSES OR COUNTERCLAIMS, WHETHER KNOWN OR UNKNOWN, ARISING PRIOR TO
THE DATE HEREOF AND HEREBY RELEASES THE AGENT, THE BANKS, THE

                                       73
<PAGE>

ISSUING BANK AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS AND
ATTORNEYS (COLLECTIVELY, THE "RELEASED PARTIES") FROM ANY AND ALL OBLIGATIONS,
INDEBTEDNESS, LIABILITY, CLAIMS, RIGHTS, CAUSES OF ACTION OR DEMANDS WHATSOEVER,
WHETHER KNOWN OR UNKNOWN, SUSPECTED OR UNSUSPECTED WHICH THE BORROWER OR ANY
GUARANTOR EVER HAD, NOW HAS, CLAIMS TO HAVE OR MAY HAVE AGAINST ANY RELEASED
PARTY ARISING PRIOR TO THE DATE HEREOF OR FROM OR IN CONNECTION WITH THIS
AGREEMENT, ANY OTHER LOAN DOCUMENT OR ANY DOCUMENTATION RELATING TO THE DEPOSIT
AND CASH MANAGEMENT SERVICES OR THE TRANSACTIONS CONTEMPLATED THEREBY.

                                   ARTICLE XV

                                   Arbitration

      Section 15.1 Arbitration. Upon the demand of any party, any Dispute shall
be resolved by binding arbitration (except as set forth in Section 15.5 below)
in accordance with the terms of this Agreement. A "Dispute" shall mean any
action, dispute, claim or controversy of any kind, whether in contract or tort,
statutory or common law, legal or equitable, now existing or hereafter arising
under or in connection with, or in any way pertaining to, any of the Loan
Documents, or any past, present or future extensions of credit and other
activities, transactions or obligations of any kind related directly or
indirectly to any of the Loan Documents, including without limitation, any of
the foregoing arising in connection with the exercise of any self-help,
ancillary or other remedies pursuant to any of the Loan Documents. Any party may
by summary proceedings bring an action in court to compel arbitration of a
Dispute. Any party who fails or refuses to submit to arbitration following a
lawful demand by any other party shall bear all costs and expenses incurred by
such other party in compelling arbitration of any Dispute.

      Section 15.2 Governing Rules. Arbitration proceedings shall be
administered by the American Arbitration Association ("AAA") or such other
administrator as the parties shall mutually agree upon in accordance with the
AAA Commercial Arbitration Rules. All Disputes submitted to arbitration shall be
resolved in accordance with the Federal Arbitration Act (Title 9 of the United
States Code), notwithstanding any conflicting choice of law provision in any of
the Loan Documents. The arbitration shall be conducted at a location in Texas
selected by the AAA or other administrator. If there is any inconsistency
between the terms hereof and any such rules, the terms and procedures set forth
herein shall control. All statutes of limitation applicable to any Dispute shall
apply to any arbitration proceeding. All discovery activities shall be expressly
limited to matters directly relevant to the Dispute being arbitrated. Judgment
upon any award rendered in an arbitration may be entered in any court having
jurisdiction; provided however, that nothing contained herein shall be deemed to
be a waiver by any party that is a bank of the protections afforded to it under
12 U.S.C. Section 91 or any similar applicable state law.

      Section 15.3 No Waiver; Provisional Remedies, Self-Help and Foreclosure.
No provision hereof shall limit the right of any party to exercise self-help
remedies such as setoff, foreclosure against or sale of any real or personal
property collateral or security, or to obtain provisional or ancillary remedies,
including without limitation injunctive relief, sequestration,

                                       74
<PAGE>

attachment, garnishment or the appointment of a receiver, from a court of
competent jurisdiction before, after or during the pendency of any arbitration
or other proceeding. The exercise of any such remedy shall not waive the right
of any party to compel arbitration hereunder.

      Section 15.4 Arbitrator Qualifications and Powers; Awards. Arbitrators
must be active members of the State Bar of Texas with expertise in the
substantive laws applicable to the subject matter of the Dispute. Arbitrators
are empowered to resolve Disputes by summary rulings in response to motions
filed prior to the final arbitration hearing. Arbitrators (i) shall resolve all
Disputes in accordance with the substantive law of the State of Texas, (ii) may
grant any remedy or relief that a court of the State of Texas could order or
grant within the scope hereof and such ancillary relief as is necessary to make
effective any award, and (iii) shall have the power to award recovery of all
costs and fees, to impose sanctions and to take such other actions as they deem
necessary to the same extent a judge could pursuant to the Federal Rules of
Civil Procedure, the Texas Rules of Civil Procedure or other applicable law. Any
Dispute in which the amount in controversy is $5,000,000 or less shall be
decided by a single arbitrator who shall not render an award of greater than
$5,000,000 (including damages, costs, fees and expenses). By submission to a
single arbitrator, each party expressly waives any right or claim to recover
more than $5,000,000. Any Dispute in which the amount in controversy exceeds
$5,000,000 shall be decided by majority vote of a panel of three arbitrators;
provided however, that all three arbitrators must actively participate in all
hearings and deliberations.

      Section 15.5 Judicial Review. Notwithstanding anything herein to the
contrary, in any arbitration in which the amount in controversy exceeds
$25,000,000, the arbitrators shall be required to make specific, written
findings of fact and conclusions of law. In such arbitrations (i) the
arbitrators shall not have the power to make any award which is not supported by
substantial evidence or which is based on legal error, (ii) an award shall not
be binding upon the parties unless the findings of fact are supported by
substantial evidence and the conclusions of law are not erroneous under the
substantive law of the State of Texas, and (iii) the parties shall have in
addition to the grounds referred to in the Federal Arbitration Act for vacating,
modifying or correcting an award the right to judicial review of (A) whether the
findings of fact rendered by the arbitrators are supported by substantial
evidence, and (B) whether the conclusions of law are erroneous under the
substantive law of the State of Texas. Judgment confirming an award in such a
proceeding may be entered only if a court determines the award is supported by
substantial evidence and not based on legal error under the substantive law of
the State of Texas.

      Section 15.6 Miscellaneous. To the maximum extent practicable, the AAA,
the arbitrators and the parties shall take all action required to conclude any
arbitration proceedings within 180 days of the filing of the Dispute with the
AAA. No arbitrator or other party to an arbitration proceeding may disclose the
existence, content or results thereof, except for disclosures of information by
a party required in the ordinary course of its business, by applicable law or
regulations, or to the extent necessary to exercise any judicial review rights
set forth herein. If more than one agreement for arbitration by or between the
parties potentially applies to a Dispute, the arbitration provisions most
directly related to the Loan Documents or the subject matter of the Dispute
shall control. This arbitration provision shall survive termination, amendment
or expiration of any of the Loan Documents or any relationship between the
parties.

repaid on the Maturity Date.

      Section 2.4 Interest. The unpaid principal amount of the Loans shall bear
interest prior to maturity at the lesser of (a) the Maximum Rate or (b) the
Facility Rate. Accrued and unpaid interest on the Loans shall be due and payable
(a) on each Payment Date and (b) on the Maturity Date.

      Notwithstanding the foregoing, after an Event of Default and during any
continuance thereof, at the Agent's election or at the request of the Required
Lenders, the Obligations shall bear interest at a rate per annum equal to the
Default Rate. Such interest shall be payable on the earlier of demand or the
Maturity Date, as appropriate, and shall accrue until the earlier of (i) waiver
or cure of the applicable Event of Default, (ii) agreement by the Required
Lenders to rescind the charging of interest at the Default Rate, or (iii)
payment in full of the Obligations. The Lenders shall not be required to
accelerate the maturity of the Loans or to exercise any other rights or remedies
under the Loan Documents.

      Section 2.5 Use of Proceeds. The proceeds of the Loans shall be used by

each Lender will make available to the Agent at the Principal Office in

according to instructions provided by the Borrower.

      Section 2.7 Method of Payment. All payments of principal, interest, and

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). The Borrower shall, at the
time of making each such payment, specify to the Agent the sums payable by the
Borrower under this Agreement and the other Loan Documents to which such payment
is to be applied (and in the event that the Borrower fails to so specify, or if
an Event of Default has occurred and is continuing, the Agent may apply such
payment to the Obligations in such order and manner as it may elect in its sole
discretion, subject to Section 2.10 hereof). Each payment received by the Agent

Agreement or any other Loan Document shall be stated to be due on a day that is
not a Business Day, such payment may be made on the next succeeding Business
Day, and such extension of time shall in such case be included in the
computation of the payment of interest and commitment fee, as the case may be.

      Section 2.8 Voluntary Prepayment. In the event the Borrower desires to
prepay all, or a portion of the Loans, it shall notify the Agent in writing of
such desire and request that the Lenders submit to the Borrower, such amount or
amounts as each Lender determines are necessary to compensate it for any cost or
expense incurred by such Lender as a result of any prepayment, said cost or
expense to be the actual cost or expense charged to such Lender using its
customary breakage fee calculation (hereinafter referred to as "Breakage Fee").
Upon receipt of such written notice from the Borrower of its desire to make such
a prepayment, the Lenders shall obtain and furnish to the Agent and the
Borrower, within five (5) Business Days, in writing, the amount of the
respective Breakage Fee the Borrower is being charged, and upon receipt of the
amount of such charges if any, the Borrower shall make its proposed prepayment,
including therewith the Breakage Fee, within five (5) Business Days of receipt
of the written Breakage Fee amount from the Lenders. There shall be no other
premium or penalty for any prepayment.

            shall prepay the Loans in accordance with Section 2.9(c) in an
            amount equal to 100% of the amount by which aggregate Net Cash
            Proceeds received from such Asset Sales or insurance proceeds during
            any twelve month period exceeds five percent of the Borrower's
            Consolidated Net Worth, and 100% of the amount of Net Cash Proceeds
            received from any such sale/leaseback transaction.

                  (b) At any time after the Senior Debt is repaid in full, the
            Senior Lenders have no obligations to make further loans to the
            Borrower pursuant to the Senior Credit Agreement and all letters of

            secured on a dollar for dollar basis, except as expressly set forth
            in this Section 2.9(b), if the Borrower or any of its Subsidiaries
            receives Net Cash Proceeds from the issuance of Capital Stock to any
            Person, and if at such time, the Leverage Ratio equals or exceeds
            3.50 to 1.00 (based on the most recent financial information in
            Agent's possession at the time of such determination), the Borrower
            shall prepay the Loans in accordance with Section 2.9(c) in a
            principal amount equal to 50% of the amount by which aggregate Net
            Cash Proceeds received from such issuances during any twelve month
            period exceeds $2,000,000. Notwithstanding the foregoing, the
            prepayment described above shall not be required in connection with
            (i) an issuance of Capital Stock to First Reserve and (ii) an
            issuance of Capital Stock made by April 30, 2006 to any other Person
            who has made material investments in, or otherwise has long-term
            experience in managing companies in, the Borrower's industry so long
            as the aggregate Net Cash Proceeds received from such issuances
            pursuant to clause (ii) of this sentence does not exceed
            $20,000,000; provided, that, if the aggregate Net Cash Proceeds
            received from such issuances pursuant to clause (ii) of this
            sentence does exceed $20,000,000, the Borrower shall prepay the
            Loans in accordance with Section 2.9(c) in a principal amount equal
            to 50% of the amount of such excess.

                  (c) Any prepayment made under Sections 2.9(a) or (b) shall (i)
            be applied first to accrued interest and the remainder to principal
            and (ii) not be subject to any minimum payment provisions contained
            in this Agreement.

      Section 2.10 Pro Rata Treatment. Each payment and prepayment of principal

Agreement by the Lenders, the Borrower will pay the Lenders a facility fee of
$300,000.00.

      Section 2.12 Non-Receipt of Funds by the Agent. Unless the Agent shall
have been notified by the Borrower prior to the date on which the Borrower is to
make a payment to the Agent for the account of one or more of the Lenders (such
payment being herein called the "Required Payment"), which notice shall be
effective upon receipt, that the Borrower does not intend to make the Required
Payment to the Agent, the 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 Lender on such date and, if
the Borrower has not in fact made the Required Payment to the Agent, the
recipient of such payment shall, on demand, pay to the Agent the amount made
available to it together with interest thereon in respect of the period
commencing on the date such amount was so made available by the Agent

                                       17
<PAGE>

until the date the Agent recovers such amount at a rate per annum equal to the
Federal Funds Rate for such period.

      Section 2.13 Withholding Tax Exemption. Each Lender that is not
incorporated under the laws of the United States of America or a state thereof
agrees that it will deliver to the Borrower and the Agent two duly completed
copies of Form W-8BEN or W-8ECI, certifying in either case that such Lender is
entitled to receive payments from the Borrower under any Loan Document without
deduction or withholding of any United States federal income taxes. Each Lender
which so delivers a Form W-8BEN or W-8ECI further undertakes to deliver to the
Borrower and the Agent two additional copies of such form (or a successor form)
on or before the date such form expires or becomes obsolete or after the
occurrence of any event requiring a change in the most recent form so delivered
by it, and such amendments thereto or extensions or renewals thereof as may be
reasonably requested by the Borrower or the Agent, in each case certifying that
such Lender is entitled to receive payments from the Borrower under any Loan
Document without deduction or withholding of any United States federal income
taxes, unless an event (including without limitation any change in treaty, law
or regulation) has occurred prior to the date on which any such delivery would
otherwise be required which renders all such forms inapplicable or which would
prevent such Lender from duly completing and delivering any such form with
respect to it and such Lender advises the Borrower and the Agent that it is not
capable of receiving such payments without any deduction or withholding of
United States federal income tax. Notwithstanding any provisions of this
agreement to the contrary, the Borrower shall make payments net of, and after
deductions for, taxes and shall not be required to increase any such amount
payable to any non-U.S. Lender that fails to comply with this section.

      Section 2.14 Computation of Interest. Interest on the Loans and all other
amounts payable by the Borrower hereunder shall be computed on the basis of a
year of 365 or 366 days, as the case may be, and the actual number of days
elapsed (including the first day but excluding the last day).

      Section 2.15 Capital Adequacy. If after the date hereof, any adoption or
implementation of any applicable law, rule, or regulation regarding capital
adequacy (including, without limitation, any law, rule, or regulation
implementing the Basle Accord), or any change therein, or any change in the
interpretation or administration thereof by any central bank or other
Governmental Authority charged with the interpretation or administration
thereof, or compliance by a Lender (or its parent) with any guideline, request,
or directive regarding capital adequacy (whether or not having the force of law)
of any such central bank or other Governmental Authority (including, without
limitation, any guideline or other requirement implementing the Basle Accord),
has or would have the effect of reducing the rate of return on such Lender's (or
its parent's) capital as a consequence of its obligations hereunder or the
transactions contemplated hereby to a level below that which such Lender (or its
parent) could have achieved but for such adoption, implementation, change, or
compliance (taking into consideration such Lender's policies with respect to
capital adequacy) by an amount deemed by such Lender to be material, then from
time to time, within ten Business Days after demand by such Lender (with a copy
to the Agent), the Borrower agrees to pay to such Lender (or its parent) such
additional amount or

                                       18
<PAGE>

amounts as will compensate such Lender for such reduction. Any such demand shall
be accompanied by a certificate of such Lender claiming compensation under this
Section and setting forth in reasonable detail the calculation of the additional
amount or amounts to be paid to it hereunder shall be conclusive (absent
manifest error), provided that the determination thereof is made on a reasonable
basis. In determining such amount or amounts, such Lender may use any reasonable
averaging and attribution methods.

            Obligated Party shall not, within said period of 30 days, or such
            longer period during which execution of the same shall have been
            stayed, appealed therefrom and cause the execution thereof to be
            stayed during such appeal.

            Obligations or the Senior Debt) in excess of $2,250,000, which

            maturity of such Debt shall actually have been accelerated or such

                  (j) This Agreement or any other Loan Document shall cease to
            be in full force and effect or shall be declared null and void or
            the validity or enforceability thereof shall be contested or
            challenged by the Borrower, any Subsidiary, any Obligated Party or
            any of their respective shareholders, or the Borrower or any
            Obligated Party shall deny that it has any further liability or
            obligation under any of the Loan Documents, or any lien or security
            interest created by the Loan Documents shall for any reason cease to
            be a valid, first priority perfected security interest in and lien
            upon any of the Collateral purported to be covered thereby.

                  (k) The Borrower, any of its Subsidiaries, or any Obligated
            Party, or any of their properties, revenues, or assets, shall become

            Transaction involving any Plan; (ii) any Reportable Event with
            respect to any Plan; (iii) the filing under Section 4041 of ERISA of
            a notice of intent to terminate any Plan or the termination of any
            Plan; (iv) any event or circumstance that might constitute grounds
            entitling the PBGC to institute proceedings under Section 4042 of
            ERISA for the termination of, or for the appointment of a trustee to
            administer, any Plan, or the institution by the PBGC of any such
            proceedings; or (v) complete or partial withdrawal under Section
            4201 or 4204 of ERISA from a Multiemployer Plan or the
            reorganization, insolvency, or termination of any Multiemployer
            Plan; and in each case above, such event or condition, together with
            all other events or conditions, if any, have subjected or could in
            the reasonable opinion of Required Banks subject the Borrower to any
            tax, penalty, or other liability to a Plan, a Multiemployer Plan,
            the PBGC, or otherwise (or any combination thereof) which in the
            aggregate exceed or could reasonably be expected to exceed
            $2,250,000.

                  (n) Any event or circumstance shall occur or exist that causes
            a Material Adverse Effect.

      Section 9.2 Remedies Upon Default. If any Event of Default shall occur and
be continuing, the Agent may (and if directed by Required Lenders, shall)
without notice terminate any commitment to lend hereunder and declare the
Obligations or any part thereof to be immediately due and payable, and the same
shall thereupon become immediately due and payable, without notice, demand,
presentment, notice of dishonor, notice of acceleration, notice of intent to
accelerate, notice of intent to demand, protest, or other formalities of any
kind, all of which are hereby expressly waived by the Borrower; provided,
however, that upon the occurrence of an Event of Default under Section 9.1 (d)
or Section 9.1(e), any commitment of the lenders to lend hereunder shall
automatically terminate, and the Obligations shall become

                                       44
<PAGE>

immediately due and payable without notice, demand, presentment, notice of
dishonor, notice of acceleration, notice of intent to accelerate, notice of
intent to demand, protest, or other formalities of any kind, all of which are
hereby expressly waived by the Borrower. Except as otherwise expressly set forth
herein, if any Event of Default shall occur and be continuing, the Agent may
exercise all rights and remedies available to it in law or in equity, under the
Loan Documents, or otherwise.

      Section 9.3 Performance by the Agent. If the Borrower shall fail to
perform any covenant or agreement contained in any of the Loan Documents, the
Agent may, at the direction of the Required Lenders, perform or attempt to
perform such covenant or agreement on behalf of the Borrower. In such event, the
Borrower shall, at the request of the Agent, promptly pay any amount expended by
the Agent or the Lenders in connection with such performance or attempted
performance to the Agent, together with interest thereon at the Default Rate
from and including the date of such expenditure to but excluding the date such
expenditure is paid in full. Notwithstanding the foregoing, it is expressly
agreed that neither the Agent nor any Lender shall have any liability or
responsibility for the performance of any obligation of the Borrower under this
Agreement or any other Loan Document except for Agent's gross negligence or
willful misconduct.

                                   ARTICLE X

                                    The Agent

      Section 10.1 Appointment, Powers and Immunities. In order to expedite the
various transactions contemplated by this Agreement, the Lenders hereby
irrevocably appoint and authorize Agent to act as their agent hereunder and
under each of the other Loan Documents. The Agent consents to such appointment
and agrees to perform the duties of the Agent as specified herein. The Lenders
authorize and direct the Agent to take such action in their name and on their
behalf under the terms and provisions of the Loan Documents and to exercise such
rights and powers thereunder as are specifically delegated to or required of the
Agent for the Lenders, together with such rights and powers as are reasonably
incidental thereto. The Agent is hereby expressly authorized to act as the Agent
on behalf of the Lenders:

                  (a) To receive on behalf of each of the Lenders and the Agent
            any payment of principal, interest, fees or other amounts paid
            pursuant to this Agreement and the Notes, and to distribute to each
            Lender and the Agent, or any or some of them its share of all
            payments so received as provided in this Agreement;

                  (b) To receive all documents and items to be furnished under
            the Loan Documents;

<PAGE>

                  (d) To arrange for the means whereby the funds of the Lenders
            are to be made available to the Borrower;

                  (e) To distribute to the Lenders information, requests,
            notices, payments, prepayments, documents and other items received
            from the Borrower, the other Obligated Parties, and other Persons;

                  (f) To execute and deliver to the Borrower, the other
            Obligated Parties, and other Persons, all requests, demands,
            approvals, notices, and consents received from the Lenders;

                  (g) To the extent permitted by the Loan Documents, to exercise
            on behalf of itself and each Lender all rights and remedies of
            Lenders upon the occurrence of any Event of Default;

                  (h) To enter into the Intercreditor Agreement;

                  (i) To accept, execute, and deliver any security documents as
            the secured party, including, without limitation all financing
            statements; and

                  (j) To take such other actions as may be requested by Required
            Lenders.

      Neither the Agent nor any of its Affiliates, officers, directors,
employees, attorneys, or agents shall be liable for any action taken or omitted
to be taken by any of them hereunder or otherwise in connection with this
Agreement or any of the other Loan Documents except for its or their own gross
negligence or willful misconduct. Without limiting the generality of the
preceding sentence, the Agent (i) may treat the payee of any Note as the holder
thereof until the Agent receives an Assignment and Acceptance signed by such
payee; (ii) shall have no duties or responsibilities except those expressly set
forth in this Agreement and the other Loan Documents, and shall not by reason of
this Agreement or any other Loan Document be a trustee or fiduciary for any
Lender; (iii) shall not be required to initiate any litigation or collection
proceedings hereunder or under any other Loan Document except to the extent
requested by the Required Lenders; (iv) shall not be responsible to the Lenders
for any recitals, statements, representations or warranties contained in this
Agreement or any other Loan Document, or any certificate or other document
referred to or provided for in, or received by any of them under, this Agreement
or any other Loan Document or for the value, validity, effectiveness,
enforceability, or sufficiency of this Agreement or any other Loan Document or
any other document referred to or provided for herein or therein or for any
failure by any Person to perform any of its obligations hereunder or thereunder;
(v) may consult with legal counsel (including counsel for the Borrower),
independent public accountants, and other experts selected by it and shall not
be liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants, or experts; and (vi)
shall incur no liability under or in respect of any Loan Document by acting upon
any notice, consent, certificate, or other instrument or writing believed by it
to be genuine and signed or sent by the

                                       46
<PAGE>

proper party or parties. As to any matters not expressly provided for by this
Agreement, the Agent shall in all cases be fully protected in acting, or in
refraining from acting, hereunder in accordance with instructions signed by the
Required Lenders, and such instructions of the Required Lenders and any action
taken or failure to act pursuant thereto shall be binding on all of the Lenders;
provided, however, that the Agent shall not be required to take any action which
exposes the Agent to personal liability or which is contrary to this Agreement
or any other Loan Document or applicable law.

      Section 10.2 Rights of Agent as a Lender. With respect to its Commitment
hereunder, the portion of the Loans funded by it and the Note issued to it, the
Agent 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 as the Agent and the term "Lender" or "Lenders" shall, unless the
context otherwise indicates, include the Agent in its individual capacity. The
Agent and its Affiliates may (without having to account therefor to any Lender)
accept deposits from, lend money to, act as trustee under indentures of, provide
merchant banking services to, and generally engage in any kind of business with
the Borrower, any of its Subsidiaries, any other Obligated Party, and any other
Person who may do business with or own securities of the Borrower, any
Subsidiary, or any other Obligated Party, all as if it were not acting as the
Agent and without any duty to account therefor to the Lenders.

      Section 10.3 Sharing of Payments, Etc. If any Lender shall obtain any
payment of any principal of or interest on the Loans made by it under this
Agreement or payment of any other obligation under the Loan Documents then owed
by the Borrower or any other Obligated Party to such Lender, whether voluntary,
involuntary, through the exercise of any right of setoff, banker's lien,
counterclaim or similar right, or otherwise, in excess of its pro rata share,
such Lender shall promptly purchase from the other Lenders participations in
those portions of the Loans held by them hereunder in such amounts, and make
such other adjustments from time to time as shall be necessary to cause such
purchasing Lender to share the excess payment ratably with each of the other
Lenders in accordance with its pro rata portion thereof. To such end, all of the
Lenders shall make appropriate adjustments among themselves (by the resale of
participations sold or otherwise) if all or any portion of such excess payment
is thereafter rescinded or must otherwise be restored. The Borrower agrees, to
the fullest extent it may effectively do so under applicable law, that any
Lender so purchasing a participation in those portions of the Loans made by the
other Lenders may exercise all rights of setoff, banker's lien, counterclaim, or
similar rights with respect to such participation as fully as if such Lender
were a direct holder of those portions of the Loans to the Borrower 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 the Borrower.

      Section 10.4 Indemnification. THE LENDERS HEREBY AGREE TO INDEMNIFY THE
AGENT FROM AND HOLD THE AGENT HARMLESS AGAINST (TO THE EXTENT NOT REIMBURSED
UNDER SECTIONS 11.1 AND 11.2, BUT WITHOUT LIMITING THE OBLIGATIONS OF THE
BORROWER UNDER SECTIONS 11.1 AND 11.2), RATABLY IN

                                       47
<PAGE>

ACCORDANCE WITH THEIR RESPECTIVE COMMITMENTS, ANY AND ALL LIABILITIES,
OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, DEFICIENCIES,
SUITS, COSTS, EXPENSES (INCLUDING ATTORNEYS' FEES), AND DISBURSEMENTS OF ANY
KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED BY, OR ASSERTED
AGAINST THE AGENT IN ANY WAY RELATING TO OR ARISING OUT OF ANY OF THE LOAN
DOCUMENTS OR ANY ACTION TAKEN OR OMITTED TO BE TAKEN BY THE AGENT UNDER OR IN
RESPECT OF ANY OF THE LOAN DOCUMENTS; PROVIDED, THAT NO LENDER SHALL BE LIABLE
FOR ANY PORTION OF THE FOREGOING TO THE EXTENT CAUSED BY THE AGENT'S GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT. WITHOUT LIMITATION OF THE FOREGOING, IT IS THE
EXPRESS INTENTION OF THE LENDERS THAT THE AGENT SHALL BE INDEMNIFIED HEREUNDER
FROM AND HELD HARMLESS AGAINST ALL OF SUCH LIABILITIES, OBLIGATIONS, LOSSES,
DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, DEFICIENCIES, SUITS, COSTS, EXPENSES
(INCLUDING ATTORNEYS' FEES), AND DISBURSEMENTS OF ANY KIND OR NATURE DIRECTLY OR
INDIRECTLY ARISING OUT OF OR RESULTING FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE
OF THE AGENT. WITHOUT LIMITING ANY OTHER PROVISION OF THIS SECTION, EACH LENDER
AGREES TO REIMBURSE THE AGENT PROMPTLY UPON DEMAND FOR ITS PRO RATA SHARE
(CALCULATED ON THE BASIS OF THE COMMITMENTS) OF ANY AND ALL OUT-OF-POCKET
EXPENSES (INCLUDING ATTORNEYS' FEES) INCURRED BY THE AGENT IN CONNECTION WITH
THE PREPARATION, EXECUTION, DELIVERY, ADMINISTRATION, MODIFICATION, AMENDMENT OR
ENFORCEMENT (WHETHER THROUGH NEGOTIATIONS, LEGAL PROCEEDINGS, OR OTHERWISE) OF,
OR LEGAL ADVICE IN RESPECT OF RIGHTS OR RESPONSIBILITIES UNDER, THE LOAN
DOCUMENTS, TO THE EXTENT THAT THE AGENT IS NOT REIMBURSED FOR SUCH EXPENSES BY
THE BORROWER.

      Section 10.5 Independent Credit Decisions. Each Lender agrees that it has
independently and without reliance on the Agent or any other Lender, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis of the Borrower and the Obligated Parties and decision to enter
into this Agreement and that it will, independently and without reliance upon
the Agent or any other Lender, and based upon 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 Agreement or any of the
other Loan Documents. The Agent shall not be required to keep itself informed as
to the performance or observance by the Borrower or any Obligated Party of this
Agreement or any other Loan Document or to inspect the properties or books of
the Borrower or any Obligated Party. Except for notices, reports and other
documents and information expressly required to be furnished to the Lenders by
the Agent hereunder or under the other Loan Documents, the Agent shall not have
any duty or responsibility to provide any Lender with any credit or other
financial information concerning the affairs, financial condition or business of
the Borrower or any

                                       48

Obligated Party (or any of their Affiliates) which may come into the possession
of the Agent or any of its Affiliates.

      Section 10.6 Several Commitments. The commitments to lend and other
obligations of the Lenders under this Agreement are several. The default by the
Lender in renewing, rearranging and extending the Debt evidenced by the Existing
Note and funding the Additional Advance in accordance with its Commitment
hereunder shall not relieve the other Lenders of their obligations under this
Agreement. In the event of any default by any Lender in making its portion of
the Additional Advance, each nondefaulting Lender shall be obligated to make its
portion of the Additional Advance but shall not be obligated to advance the
amount which the defaulting Lender was required to advance hereunder. In no
event shall any Lender be required to advance an amount or amounts which shall
in the aggregate exceed such Lender's Commitment, as applicable. No Lender shall
be responsible for any act or omission of any other Lender.

      Section 10.7 Successor Agent. Subject to the appointment and acceptance of
a successor Agent as provided below, the Agent may resign at any time by giving
notice thereof to the Lenders and the Borrower and the Agent may be removed at
any time with or without cause by the Required Lenders. Upon any such
resignation or removal, the Required Lenders (with the consent of the Borrower,
with consent will not be unreasonably withheld) will have the right to appoint a
successor Agent. If no successor Agent shall have been so appointed by the
Required Lenders and shall have accepted such appointment within thirty (30)
days after the retiring Agent's giving notice of resignation or the Required
Lenders' removal of the retiring Agent, then the retiring Agent may, on behalf
of the Lenders, appoint a successor Agent, which shall be a commercial bank
organized under the laws of the United States of America or any State thereof
and having combined capital and surplus of at least $500,000,000.00. Upon the
acceptance of its appointment as successor Agent, such successor Agent shall
thereupon succeed to and become vested with all rights, powers, privileges,
immunities, and duties of the resigning or removed Agent, and the resigning or
removed Agent shall be discharged from its duties and obligations under this
Agreement and the other Loan Documents. After any Agent's resignation or removal
as Agent, the provisions of this Article X shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was the Agent.

limitation, all costs, expenses, and other charges incurred in connection with

      Section 11.2 Indemnification. THE BORROWER SHALL INDEMNIFY EACH OF THE
AGENT AND THE LENDERS AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE OFFICERS,
DIRECTORS, EMPLOYEES, ATTORNEYS, AND AGENTS FROM, AND HOLD EACH OF THEM HARMLESS
AGAINST, ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DAMAGES, PENALTIES, JUDGMENT,
DISBURSEMENTS, COSTS, AND EXPENSES (INCLUDING ATTORNEYS' FEES) TO WHICH ANY OF
THEM MAY BECOME SUBJECT WHICH DIRECTLY OR INDIRECTLY ARISE FROM OR RELATE TO (A)

ENFORCEMENT OF ANY OF THE LOAN DOCUMENTS, (B) ANY OF THE TRANSACTIONS
CONTEMPLATED BY THE LOAN DOCUMENTS, (C) ANY BREACH BY THE BORROWER OF ANY
REPRESENTATION, WARRANTY, COVENANT, CONTAINED IN ANY OF THE LOAN DOCUMENTS, (D)
THE PRESENCE, RELEASE, THREATENED RELEASE, DISPOSAL, REMOVAL, OR CLEANUP OF ANY
HAZARDOUS MATERIAL LOCATED ON, ABOUT, WITHIN, OR AFFECTING ANY OF THE PROPERTIES
OR ASSETS OF THE BORROWER OR ANY SUBSIDIARY, OR (E) ANY INVESTIGATION,
LITIGATION, OR OTHER PROCEEDING, INCLUDING, WITHOUT LIMITATION, ANY THREATENED
INVESTIGATION, LITIGATION, OR OTHER PROCEEDING, RELATING TO ANY OF THE
FOREGOING.

      Section 11.3 Limitation of Liability. Neither the Agent or the Lenders nor
any Affiliate, officer, director, employee, attorney, or agent of the Agent or
the Lenders shall have any liability with respect to, and the Borrower hereby
waives, releases, and agrees not to sue any of them upon, any claim for any
special, indirect, incidental, or consequential damages suffered or incurred by
the Borrower in connection with, arising out of, or in any way related to, this
Agreement or any of the other Loan Documents, or any of the transactions
contemplated by this Agreement or any of the other Loan Documents. The Borrower
hereby waives, releases, and agrees not to sue the Agent or the Lenders or any
of such Person's Affiliates, officers, directors, employees, attorneys, or
agents for punitive damages in respect of any claim in connection with, arising
out of, or in any way related to, this Agreement or any of the other Loan
Documents, or any of the transactions contemplated by this Agreement or any of
the other Loan Documents. Nothing contained in this Section shall affect the
rights of

                                       50
<PAGE>

the Borrower to collect actual damages awarded to them against any of the
Agents, the Lenders or any Affiliate of any of the foregoing Persons.

      Section 11.4 No Duty. All attorneys, accountants, appraisers, and other
professional Persons and consultants retained by any of the Agent or the Lenders
shall have the right to act exclusively in the interest of such Persons and
shall have no duty of disclosure, duty of loyalty, duty of care, or other duty
or obligation of any type or nature whatsoever to the Borrower or any of the
Borrower's shareholders or any other Person.

      Section 11.5 Lender Not Fiduciary. The relationship between the Borrower,
on one hand, and the Agent and the Lenders, on the other hand, is solely that of
debtor and creditor, and no such Person has any fiduciary or other special
relationship with the Borrower, and no term or condition of any of the Loan
Documents shall be construed so as to deem the relationship between the Borrower
and such Persons to be other than that of debtor and creditor.

      Section 11.6 No Waiver; Cumulative Remedies. No failure on the part of any
of the Agent or the Lenders to exercise and no delay in exercising, and no
course of dealing with respect to, any right, power, or privilege under this
Agreement shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power, or privilege under this Agreement preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies provided for in this Agreement and the other
Loan Documents are cumulative and not exclusive of any rights and remedies
provided by law.

      Section 11.7 Successors and Assigns.

                  (a) This Agreement shall be binding upon and inure to the
            benefit of the parties hereto and their respective successors and
            assigns. The Borrower may not assign or transfer any of its rights
            or obligations hereunder without the prior written consent of the
            Agent and all of the Lenders. Any Lender may sell participations to
            one or more banks or other institutions in or to all or a portion of
            its rights and obligations under this Agreement and the other Loan
            Documents (including, without limitation, all or a portion of its
            Commitment and its Percentage of outstanding principal of the
            Loans); provided, however, that (i) such Lender's obligations under
            this Agreement and the other Loan Documents (including, without
            limitation, its Commitment and its Percentage of outstanding
            principal of the Loans) shall remain unchanged, (ii) such Lender
            shall remain solely responsible to the Borrower for the performance
            of such obligations, (iii) such Lender shall remain the holder of
            its Note for all purposes of this Agreement, and (iv) the Borrower
            shall continue to deal solely and directly with such Lender in
            connection with such Lender's rights and obligations under this
            Agreement and the other Loan Documents. Participants have no rights
            under the Loan Documents except as provided below. Subject to the
            following, each Lender may obtain, on behalf of its participants,
            the benefits of Section 2.14 with respect to all participations in
            its part of the Obligations outstanding from time to time, so long
            as Borrower is not obligated to pay any amount in excess of the
            amount

                                       51
<PAGE>

            that would be due to that Lender under Section 2.14 calculated as
            though no participations have been made. No Lender may sell any
            participating interest under which the participant has any rights to
            approve any amendment, modification, or waiver of any Loan Document
            except as to matters in Section 11.7(a), (b) and (c).

                  (b) The Borrower and each of the Lenders agree that any Lender
            (the "Assigning Lender") may, with the Agent's consent (which
            consent shall not be unreasonably withheld) and unless an Event of
            Default has occurred, the Borrower's consent, which consent of the
            Borrower shall not be unreasonably withheld or delayed, at any time
            assign to one or more Eligible Assignees all, or a proportionate
            part of all, of its rights and obligations under this Agreement and
            the other Loan Documents (including, without limitation, its
            Commitment and its Percentage of outstanding principal of the Loans)
            (each an "Assignee"); provided, however, that (i) except in the case
            of an assignment of all of a Lender's rights and obligations under
            this Agreement and the other Loan Documents, the amount of the
            Commitment and the amount of outstanding principal of the Loans of
            the Assigning Lender being assigned pursuant to each assignment
            (determined as of the date of the Assignment and Acceptance with
            respect to such assignment) shall in no event be less than
            $5,000,000, and (ii) the parties to each such assignment shall
            execute and deliver to the Agent for its acceptance and recording in
            the Register (as defined below), an Assignment and Acceptance,
            together with the Note subject to such assignment, and a processing
            and recordation fee of $5,000 to be paid by the Assignee. Upon such
            execution, delivery, acceptance, and recording, from and after the
            effective date specified in each Assignment and Acceptance, which
            effective date shall be at least five Business Days after the
            execution thereof, or, if so specified in such Assignment and
            Acceptance, the date of acceptance thereof by the Agent, (x) the
            assignee thereunder shall be a party hereto as a "Lender" and, to
            the extent that rights and obligations hereunder have been assigned
            to it pursuant to such Assignment and Acceptance, have the rights
            and obligations of a Lender hereunder and under the Loan Documents
            and (y) the Lender that is an assignor thereunder shall, to the
            extent that rights and obligations hereunder have been assigned by
            it pursuant to such Assignment and Acceptance, relinquish its rights
            and be released from its obligations under this Agreement and the
            other Loan Documents (and, in the case of an Assignment and
            Acceptance covering all or the remaining portion of a Lender's
            rights and obligations under the Loan Documents, such Lender shall
            cease to be a party thereto); provided that the Obligations of the
            Borrower under Sections 2.14, 11.1 and 11.2 shall continue to apply
            to such Lender.

                  (c) By executing and delivering an Assignment and Acceptance,
            the Lender that is an assignor thereunder and the assignee
            thereunder confirm to and agree with each other and the other
            parties hereto as follows: (i) other than as provided in such
            Assignment and Acceptance, such Assigning Lender makes no
            representation or warranty and assumes no responsibility with
            respect to any statements, warranties, or representations made in or
            in connection with the Loan Documents or the execution,

                                       52
<PAGE>

            legality, validity, and enforceability, genuineness, sufficiency, or
            value of the Loan Documents or any other instrument or document
            furnished pursuant thereto; (ii) such Assigning Lender makes no
            representation or warranty and assumes no responsibility with
            respect to the financial condition of the Borrower or any Obligated
            Party or the performance or observance by the Borrower or any
            Obligated Party of its obligations under the Loan Documents; (iii)
            such assignee confirms that it has received a copy of the other Loan
            Documents, together with copies of the current financial statements
            dated a date acceptable to such assignee and such other documents
            and information as it has deemed appropriate to make its own credit
            analysis and decision to enter into such Assignment and Acceptance;
            (iv) such assignee will, independently and without reliance upon the
            Agent or such assignor and based on such documents and information
            as it shall deem appropriate at the time, continue to make its own
            credit decisions in taking or not taking action under this Agreement
            and the other Loan Documents; (v) such assignee confirms that it is
            an Eligible Assignee; (vi) such assignee appoints and authorizes the
            Agent to take such action as agent on its behalf and exercise such
            powers under the Loan Documents as are delegated to the Agent by the
            terms thereof, together with such powers as are reasonably
            incidental thereto; and (vii) such assignee agrees that it will
            perform in accordance with their terms all of the obligations which
            by the terms of the Loan Documents are required to be performed by
            it as a Lender.

                  (d) The Agent shall maintain at its Principal Office a copy of
            each Assignment and Acceptance delivered to and accepted by it and a
            register for the recordation of the names and addresses of the
            Lenders and the Commitment of and principal amount of the Loans
            owing to, each Lender from time to time (the "Register"). The
            entries in the Register shall be conclusive and binding for all
            purposes, absent manifest error, and the Borrower, the Agent and the
            Lenders may treat each Person whose name is recorded in the Register
            as a Lender hereunder for all purposes under the Loan Documents. The
            Register shall be available for inspection by the Borrower or any
            Lender at any reasonable time and from time to time upon reasonable
            prior notice.

                  (e) Upon its receipt of an Assignment and Acceptance executed
            by an Assigning Lender and assignee representing that it is an
            Eligible Assignee, together with any Note subject to such
            assignment, the Agent shall, if such Assignment and Acceptance has
            been completed and is in the form satisfactory to the Agent in its
            sole discretion, (i) accept such Assignment and Acceptance, (ii)
            record the information contained therein in the Register, and (iii)
            give prompt written notice thereof to the Borrower. Within five (5)
            Business Days after its receipt of such notice, the Borrower, at its
            expense, shall execute and deliver to the Agent in exchange for the
            surrendered Note, a new Note to the order of such Eligible Assignee
            in an amount equal to the amount of outstanding principal of the
            Loans assumed by it pursuant to such Assignment and Acceptance and,
            if the Assigning Lender has retained a portion of its portion of the
            Loans, a new Note to the order of the Assigning Lender in an

                                       53
<PAGE>

            amount equal to the amount of outstanding principal of the Loans
            retained by it hereunder (each such promissory note shall constitute
            a "Note", as applicable, for purposes of the Loan Documents). Such
            new Notes shall be in an aggregate principal amount of the
            surrendered Notes, shall be dated the last interest payment date
            prior to the effective date of such Assignment and Acceptance, and
            shall otherwise be in substantially the form of the Notes initially
            issued pursuant hereto with appropriate changes.

                  (f) Any Lender may, in connection with any assignment or
            participation or proposed assignment or participation pursuant to
            this Section, disclose to the assignee or participant or proposed
            assignee or participant, any information relating to the Borrower or
            its Subsidiaries furnished to such Lender by or on behalf of the
            Borrower or its Subsidiaries.

      Section 11.8 Survival. All representations and warranties made in this
Agreement or any other Loan Documents or in any document, statement, or
certificate furnished in connection with this Agreement shall survive the
execution and delivery of this Agreement and the other Loan Documents, and no
investigation by any of the Agent or the Lenders or any closing shall affect the
representations and warranties or the right of any such Person to rely upon
them. Without prejudice to the survival of any other obligation of the Borrower
hereunder, the obligations of the Borrower under Sections 2.14, 11.1 and 11.2
shall survive repayment of the Notes and termination of the Lenders' commitments
to lend hereunder.

      Section 11.9 ENTIRE AGREEMENT; AMENDMENTS. THIS AGREEMENT, THE NOTES AND
THE OTHER LOAN DOCUMENTS REFERRED TO HEREIN EMBODY THE FINAL, ENTIRE AGREEMENT
AMONG THE PARTIES HERETO AND SUPERSEDE ANY AND ALL PRIOR COMMITMENTS,
AGREEMENTS, REPRESENTATIONS, AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL,
RELATING TO THE SUBJECT MATTER HEREOF AND MAY NOT BE CONTRADICTED OR VARIED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS
OF THE PARTIES HERETO. THERE ARE NO ORAL AGREEMENTS AMONG THE PARTIES HERETO. No
amendment, modification or waiver of, or consent with respect to, any provision
of this Agreement or the Notes shall in any event be effective unless the same
shall be in writing and signed and delivered by the Borrower and the Required
Lenders, and then any such amendment, modification, waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given. No amendment, modification, waiver or consent shall change the Percentage
of any Lender without the consent of such Lender. No amendment, modification,
waiver or consent shall (a) extend or increase the amount of the Commitments,
(b) extend the date for payment of any principal of or interest on the Loans or
any fees or other amounts payable hereunder, (c) reduce the principal amount of
the Loans, the rate of interest thereof or any fees or other amounts payable
hereunder, (d) release a Guaranty Agreement or all or substantially all of the
Collateral, or (e) reduce the aggregate Percentage required to effect an
amendment, modification, waiver or consent without, in each case, the consent of
all Lenders. No provisions of Article X or other provision of this Agreement

                                       54
<PAGE>

affecting the Agent in its capacity as such shall be amended, modified or waived
without the consent of the Agent. If, in connection with any proposed amendment,
waiver or consent (a "Proposed Change"):

                  (i) requiring the consent of all Lenders, the consent of
            Required Lenders is obtained, but the consent of other Lenders is
            not obtained (any such Lender whose consent is not obtained as
            described in this clause (I) and in clause (ii) below being referred
            to as a "Non-Consenting Lender"), or

                  (ii) requiring the consent of Required Lenders, the consent of
            Required Lenders is obtained,

then, so long as the Agent is not a Non-Consenting Lender, at the Borrower's
request, the Agent or an Eligible Assignee shall have the right (but not the
obligation) with the Agent's approval, to purchase from the Non-Consenting
Lenders' outstanding Percentage of the Loans for an amount equal to the
principal balances thereof and all accrued interest and fees with respect
thereto through the date of sale pursuant to Assignment and Acceptance(s),
without premium or discount.

      Section 11.10 Maximum Interest Rate. No provision of this Agreement or any
other Loan Document shall require the payment or the collection of interest in
excess of the maximum amount permitted by applicable law. If any excess of
interest in such respect is hereby provided for, or shall be adjudicated to be
so provided, in any Loan Document or otherwise in connection with this loan
transaction, the provisions of this Section shall govern and prevail and neither
the Borrower nor the sureties, guarantors, successors, or assigns of the
Borrower shall be obligated to pay the excess amount of such interest or any
other excess sum paid for the use, forbearance, or detention of sums loaned
pursuant hereto. In the event any of the Agent or the Lenders ever receives,
collects, or applies as interest any such sum, such amount which would be in
excess of the maximum amount permitted by applicable law shall be applied as a
payment and reduction of the principal of the indebtedness evidenced by the
Notes; and, if the principal of the Notes has been paid in full, any remaining
excess shall forthwith be paid to the Borrower. In determining whether or not
the interest paid or payable exceeds the Maximum Rate, the Borrower and the
Agent and the Lenders shall, to the extent permitted by applicable law, (a)
characterize any non-principal payment as an expense, fee, or premium rather
than as interest, (b) exclude voluntary prepayments and the effects thereof; and
(c) amortize, prorate, allocate, and spread in equal or unequal parts the total
amount of interest throughout the entire contemplated term of the indebtedness
evidenced by the Notes so that interest for the entire term does not exceed the
Maximum Rate.

      Section 11.11 Notices. All notices and other communications provided for
in this Agreement and the other Loan Documents to which the Borrower is a party
shall be in writing and may be telecopied (faxed), mailed by certified mail
return receipt requested, or delivered to the intended recipient at the "Address
for Notices" specified below its name on the signature pages hereof; or, as to
any party at such other address as shall be designated by such party in a

                                       55
<PAGE>

notice to the other party given in accordance with this Section. Except as
otherwise provided in this Agreement, all such communications shall be deemed to
have been duly given when transmitted by telecopy, subject to telephone
confirmation of receipt, or when personally delivered to, in the case of a
mailed notice, when duly deposited in the mails, in each case given or addressed
as aforesaid; provided, however, notices to the Agent pursuant to Article II
shall not be effective until received by the Agent.

      Section 11.12 GOVERNING LAW; VENUE; SERVICE OF PROCESS. THIS AGREEMENT
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
TEXAS AND THE APPLICABLE LAWS OF THE UNITED STATES OF AMERICA. THIS AGREEMENT
HAS BEEN ENTERED INTO IN HARRIS COUNTY, TEXAS, AND IT SHALL BE PERFORMABLE FOR
ALL PURPOSES IN HARRIS COUNTY, TEXAS. SUBJECT TO SECTION 11.19, ANY ACTION OR
PROCEEDING AGAINST THE BORROWER UNDER OR IN CONNECTION WITH ANY OF THE LOAN
DOCUMENTS MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT IN HARRIS COUNTY, TEXAS.
THE BORROWER HEREBY IRREVOCABLY (A) SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF
SUCH COURTS, AND (B) WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE
VENUE OF ANY SUCH ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT OR THAT ANY
SUCH COURT IS AN INCONVENIENT FORUM. THE BORROWER AGREES THAT SERVICE OF PROCESS

      Section 11.16 Non-Application of Chapter 346 of Texas Finance Code. The
provisions of Chapter 346 of the Texas Finance Code are specifically declared by
the parties hereto not to be applicable to this Agreement or any of the other
Loan Documents or to the transactions contemplated hereby.

      Section 11.17 Construction. The Borrower, the Agent and the Lenders
acknowledge that each of them has had the benefit of legal counsel of its own
choice and has been afforded an opportunity to review this Agreement and the
other Loan Documents with its legal counsel and that this Agreement and the
other Loan Documents shall be construed as if jointly drafted by the Borrower,
the Agent and the Lenders.

      Section 11.18 Independence of Covenants. All covenants hereunder shall be
given independent effect so that if a particular action or condition is not

exists.

      Section 11.19 WAIVER OF TRIAL BY JURY. TO THE FULLEST EXTENT PERMITTED, BY
APPLICABLE LAW, EACH OF THE BORROWER, THE AGENT AND THE BANKS HEREBY
VOLUNTARILY, KNOWINGLY, IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT TO HAVE
A JURY PARTICIPATE IN RESOLVING ANY DISPUTE (WHETHER BASED UPON CONTRACT, TORT
OR OTHERWISE) BETWEEN OR AMONG THE BORROWER AND ANY OTHER PARTY TO THIS
AGREEMENT ARISING OUT OF OR IN ANY WAY RELATED TO THIS AGREEMENT, ANY OTHER LOAN
DOCUMENTS, OR ANY RELATIONSHIP BETWEEN ANY OTHER PARTY TO THIS AGREEMENT AND THE
BORROWER. THIS PROVISION IS A MATERIAL INDUCEMENT TO THE BANKS TO PROVIDE THE
FINANCING DESCRIBED IN THIS AGREEMENT.

      Section 11.20 Amendment and Restatement; Release. This Agreement amends
and restates in its entirety the Existing Credit Agreement. The execution of
this Agreement and the other Loan Documents executed in connection herewith does
not extinguish the indebtedness outstanding in connection with the Existing
Credit Agreement nor does it constitute a novation with respect to such
indebtedness. THE BORROWER REPRESENTS AND WARRANTS THAT AS OF THE DATE HEREOF
THERE ARE NO CLAIMS OR OFFSETS AGAINST OR DEFENSES OR COUNTERCLAIMS TO ITS OR
ANY OBLIGATED PARTIES' OBLIGATIONS UNDER THE EXISTING CREDIT AGREEMENT OR THE
OTHER LOAN DOCUMENTS. TO INDUCE THE AGENT AND THE LENDERS TO ENTER INTO THIS
AGREEMENT, THE BORROWER AND, BY THE EXECUTION OF THE LOAN DOCUMENTS TO WHICH IT
IS A PARTY, EACH GUARANTOR WAIVES ANY AND ALL CLAIMS, OFFSETS, DEFENSES OR
COUNTERCLAIMS, WHETHER KNOWN OR UNKNOWN, ARISING PRIOR TO THE DATE HEREOF AND
HEREBY RELEASES THE AGENT, THE LENDERS AND THEIR RESPECTIVE OFFICERS, DIRECTORS,
EMPLOYEES, AGENTS AND ATTORNEYS (COLLECTIVELY, THE

                                       57
<PAGE>

"RELEASED PARTIES") FROM ANY AND ALL OBLIGATIONS, INDEBTEDNESS, LIABILITY,
CLAIMS, RIGHTS, CAUSES OF ACTION OR DEMANDS WHATSOEVER, WHETHER KNOWN OR
UNKNOWN, SUSPECTED OR UNSUSPECTED WHICH THE BORROWER OR ANY GUARANTOR EVER HAD,
NOW HAS, CLAIMS TO HAVE OR MAY HAVE AGAINST ANY RELEASED PARTY ARISING PRIOR TO
THE DATE HEREOF OR FROM OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY.

                                   ARTICLE XII

                                   Arbitration

      Section 12.1 Arbitration. Upon the demand of any party, any Dispute shall
be resolved by binding arbitration (except as set forth in Section 12.5 below)
in accordance with the terms of this Agreement. A "Dispute" shall mean any
action, dispute, claim or controversy of any kind, whether in contract or tort,
statutory or common law, legal or equitable, now existing or hereafter arising
under or in connection with, or in any way pertaining to, any of the Loan
Documents, or any past, present or future extensions of credit and other
activities, transactions or obligations of any kind related directly or
indirectly to any of the Loan Documents, including without limitation, any of
the foregoing arising in connection with the exercise of any self-help,
ancillary or other remedies pursuant to any of the Loan Documents. Any party may
by summary proceedings bring an action in court to compel arbitration of a
Dispute. Any party who fails or refuses to submit to arbitration following a
lawful demand by any other party shall bear all costs and expenses incurred by
such other party in compelling arbitration of any Dispute.

      Section 12.2 Governing Rules. Arbitration proceedings shall be
administered by the American Arbitration Association ("AAA") or such other
administrator as the parties shall mutually agree upon in accordance with the
AAA Commercial Arbitration Rules. All Disputes submitted to arbitration shall be
resolved in accordance with the Federal Arbitration Act (Title 9 of the United
States Code), notwithstanding any conflicting choice of law provision in any of
the Loan Documents. The arbitration shall be conducted at a location in Texas
selected by the AAA or other administrator. If there is any inconsistency
between the terms hereof and any such rules, the terms and procedures set forth
herein shall control. All statutes of limitation applicable to any Dispute shall
apply to any arbitration proceeding. All discovery activities shall be expressly
limited to matters directly relevant to the Dispute being arbitrated. Judgment
upon any award rendered in an arbitration may be entered in any court having
jurisdiction; provided however, that nothing contained herein shall be deemed to
be a waiver by any party that is a bank of the protections afforded to it under
12 U.S.C. Section 91 or any similar applicable state law.

      Section 12.3 No Waiver; Provisional Remedies, Self-Help and Foreclosure.
No provision hereof shall limit the right of any party to exercise self-help
remedies such as setoff, foreclosure against or sale of any real or personal
property collateral or security, or to obtain

                                       58
<PAGE>

provisional or ancillary remedies, including without limitation injunctive
relief, sequestration, attachment, garnishment or the appointment of a receiver,
from a court of competent jurisdiction before, after or during the pendency of
any arbitration or other proceeding. The exercise of any such remedy shall not
waive the right of any party to compel arbitration hereunder.

      Section 12.4 Arbitrator Qualifications and Powers Awards. Arbitrators must
be active members of the State Bar of Texas with expertise in the substantive
laws applicable to the subject matter of the Dispute. Arbitrators are empowered
to resolve Disputes by summary rulings in response to motions filed prior to the
final arbitration hearing. Arbitrators (i) shall resolve all Disputes in
accordance with the substantive law of the State of Texas, (ii) may grant any
remedy or relief that a court of the State of Texas could order or grant within
the scope hereof and such ancillary relief as is necessary to make effective any
award, and (iii) shall have the power to award recovery of all costs and fees,
to impose sanctions and to take such other actions as they deem necessary to the
same extent a judge could pursuant to the Federal Rules of Civil Procedure, the
Texas Rules of Civil Procedure or other applicable law. Any Dispute in which the
amount in controversy is $5,000,000 or less shall be decided by a single
arbitrator who shall not render an award of greater than $5,000,000 (including
damages, costs, fees and expenses). By submission to a single arbitrator, each
party expressly waives any right or claim to recover more than $5,000,000. Any
Dispute in which the amount in controversy exceeds $5,000,000 shall be decided
by majority vote of a panel of three arbitrators; provided however, that all
three arbitrators must actively participate in all hearings and deliberations.

      Section 12.5 Judicial Review. Notwithstanding anything herein to the
contrary, in any arbitration in which the amount in controversy exceeds
$25,000,000, the arbitrators shall be required to make specific, written
findings of fact and conclusions of law. In such arbitrations (i) the
arbitrators shall not have the power to make any award which is not supported by
substantial evidence or which is based on legal error, (ii) an award shall not
be binding upon the parties unless the findings of fact are supported by
substantial evidence and the conclusions of law are not erroneous under the
substantive law of the State of Texas, and (iii) the parties shall have in
addition to the grounds referred to in the Federal Arbitration Act for vacating,
modifying or correcting an award the right to judicial review of (A) whether the
findings of fact rendered by the arbitrators are supported by substantial
evidence, and (B) whether the conclusions of law are erroneous under the
substantive law of the State of Texas. Judgment confirming an award in such a
proceeding may be entered only if a court determines the award is supported by
substantial evidence and not based on legal error under the substantive law of
the State of Texas.

      Section 12.6 Miscellaneous. To the maximum extent practicable, the AAA,
the arbitrators and the parties shall take all action required to conclude any
arbitration proceedings within 180 days of the filing of the Dispute with the
AAA. No arbitrator or other party to an arbitration proceeding may disclose the
existence, content or results thereof, except for disclosures of information by
a party required in the ordinary course of its business, by applicable law or
regulations, or to the extent necessary to exercise any judicial review rights
set forth herein. If more than one agreement for arbitration by or between the
parties potentially applies to a Dispute, the arbitration provisions most
directly related to the Loan Documents or

                                       59
<PAGE>

the subject matter of the Dispute shall control. This arbitration provision
shall survive termination, amendment or expiration of any of the Loan Documents
or any relationship between the parties.
