ITEM 5.     OTHER EVENTS.

            On March 1, 1999 Benchmark Electronics, Inc. ("Company") and its
subsidiary BEI Electronics Ireland Limited ("BEI Ireland") completed the
previously announced purchase of certain inventory and equipment from Stratus
Computer Ireland ("Stratus"), a subsidiary of Ascend Communications, Inc.
("Ascend"). In consideration of the assets, BEI Ireland paid $48 million, an
amount representing the estimated book value of the assets being purchased as of
the closing date. The amount of the closing date payment is subject to
adjustment to actual book value within 60 days of closing.

            After the purchase, Benchmark will provide systems integration and
testing services to both Ascend and Stratus Holdings Limited, the former
Enterprise Computer Division of Stratus Computer Inc. being divested by Ascend,
for a three year period. In connection with the closing BEI Ireland has hired
260 employees of Stratus.

            Financing for the purchase was provided by a group of banks led by
Chase Bank Texas, N.A., as administrative agent (the "Agent"), pursuant to an
Amended and Restated Credit Agreement dated February 26, 1999 between the
Company, the Agent and certain other financial institutions (the "Credit
Agreement"). The Credit Agreement establishes a $105 million credit facility in
favor of the Company, of which $40 million is a term loan and $65 million is a
revolving credit facility. The Credit Agreement replaces the Company's former
$65 million facility dated February 23, 1998, of which $25 million had been a
revolving credit facility and $40 million had been a term loan.

            The term loan portion of the Credit Agreement, which was carried
forward from the Company's former credit agreement, matures March 31, 2003.
Principal on the term loan is payable in quarterly installments of $2.0 million
and payments commenced June 30, 1998. The term loan bears interest, at the
Company's option, at either the Agent's Eurodollar rate plus .875% to 1.625%, or
its prime rate, and is payable quarterly. The margin on the Eurodollar rate is
determined by reference to the Company's ratio of debt to earnings before taxes,
depreciation and amortization ("EBITDA"), and increases from .875% (when the
debt ratio is less than 1.00) to 1.625% (when the debt ratio is equal to or
greater than 2.00). Currently, $24 million is outstanding under the term loan,
bearing interest at rates ranging from 6.25% to 7.75% per annum.

            The revolving loan portion of the Credit Facility matures March 31,
2004. The Company is entitled to borrow under the revolving credit portion of
the Credit Agreement an amount equal to the lesser of $65 million or the sum of
75% of its eligible accounts receivable and 25% of its eligible inventories.
Interest on revolving credit borrowings is payable quarterly. Revolving credit
borrowings bear interest, at the Company's option, at either the Agent's
Eurodollar rate plus a margin of .875% to 1.625%, or its prime rate. The margin
on the Eurodollar rate applicable to revolving credit loans is determined by
reference to the Company's ratio of debt to EBITDA, in the


                                    -2-
<PAGE>
same manner as the term loan. Currently, $25 million in revolving loans is
outstanding under the Credit Agreement, bearing interest at rates ranging from
6.25% to 6.375% per annum.

            The Credit Agreement contains numerous affirmative and negative
business and financial covenants affecting the operation of the Company. These
covenants require, among other things, that the Company within 45 days of
closing pledge as security for the loan 65% of the ownership interest of BEI
Ireland. These covenants also require that the Company maintain certain
financial ratios, including (a) Consolidated Tangible Net Worth (as defined) for
each fiscal year beginning in 1998 of at least the sum of $60 million, plus 50%
of the Company's Consolidated Net Income (as defined) after December 31, 1997,
and plus 75% of the net proceeds from the issuance of equity securities, (b) a
Current Ratio (as defined) of more than 1.50 to 1.00 at any time, (c) a Fixed
Charge Coverage Ratio (as defined) of at least 1.10 to 1.00 as of the end of
each period, (d) a Debt Ratio (as defined) of less than 2.5 to 1.0 through
December 31, 2000, and 2.0 to 1.0 for each period thereafter, and (e) an
Interest Coverage Ratio (as defined) of at least 2.5 to 1.0 as of the end of
each period. The Credit Agreement also restricts without the consent of the
lenders the incurrence of additional indebtedness, the creation of liens on
assets of the Company and the payment of dividends and other Restricted Payments
(as defined) unless, at the time of the payment and after giving effect thereto
the Company is not in default and the total amount of such payments after
January 1, 1998 is less than the sum of $5.0 million plus Consolidated Net
Income from January 1, 1998.

            If the Company fails to comply with the payment and other terms of
the Credit Agreement, then an event of default would occur under the Credit
Agreement subject, as to certain provisions to notice and an opportunity to cure
the default. In addition, the Credit Agreement provides that (a) the occurrence
of a default under other indebtedness of the Company exceeding $2.5 million in
amount and (b) the occurrence of a "Change of Control" of the Company also
constitute an event of default. A "Change of Control" shall have occurred if any
person becomes the beneficial owner, directly or indirectly, of more than 50% of
the total voting power of all outstanding voting stock of the Company.

      This report contains certain forward-looking statements regarding the
Company's business operations. The words "expect," "estimate," "anticipate,"
"predict," and similar expressions are intended to identify these
forward-looking statements. Such statements involve risks, uncertainties and
assumptions, including but not limited to industry and economic conditions and
customer actions discussed in the Company's filings with the Securities and
Exchange Commission, and the risk of receipt of government approvals and the
satisfaction of the other conditions to closing the transaction. Should one or
more of these risks or uncertainties materialize, or should underlying
assumptions prove incorrect, actual outcomes may vary materially from those
indicated.

each Lender severally 

                                       17
<PAGE>
agrees to make revolving credit loans (each a "REVOLVING CREDIT LOAN") to the
Company. Except for in connection with a continuation or conversion pursuant to
Section 2.11, any Term Loan that is repaid or prepaid may not be reborrowed.

            (b) TYPES OF LOANS. The Revolving Credit Loans and the Term Loans
made pursuant hereto by each Lender shall, at the option of the Company, be
either Base Rate Loans or Eurodollar Loans and may be continued or converted
pursuant to Section 2.11, provided that, except as otherwise specifically
provided herein, all Loans made pursuant to the same Borrowing shall be of the
same Type.

            (c) REVOLVING CREDIT COMMITMENTS. Each Lender's Revolving Credit
Exposure shall not exceed at any one time the amount set forth opposite such
Lender's name on Annex I under the caption "Revolving Credit Commitment" (as the
same may be reduced pursuant to Section 2.9 or otherwise from time to time
modified pursuant to Section 9.7, its "REVOLVING CREDIT COMMITMENT," and
collectively for all Lenders, the "REVOLVING CREDIT COMMITMENTS"); PROVIDED,
HOWEVER, that the Aggregate Revolving Credit Exposure at any one time
outstanding shall not exceed the Maximum Available Amount in effect at such
time; and, PROVIDED, FURTHER, the aggregate principal amount of all Revolving
Credit Loans at any one time outstanding shall not exceed the difference between
(1) the Maximum Available Amount in effect at such time, and (2) the aggregate
amount of all Letter of Credit Liabilities at such time. There may be more than
one Borrowing with respect to Revolving Credit Loans on any day. Within the
foregoing limits and subject to the conditions set out in Article 3, the Company

Credit Loans, and reborrow such Revolving Credit Loans.

            (d) TERM LOAN COMMITMENTS. The Term Loans made pursuant hereto by
each Lender shall not exceed in aggregate principal amount outstanding the
amount set forth opposite such Lender's name on Annex I under the caption "Term
Loan Commitment" (its "TERM LOAN COMMITMENT," and collectively for all Lenders,

Commitment not utilized on the Closing Date, as defined in the Existing Credit
Agreement, shall be permanently canceled. Any Term Loans that are repaid or

each Borrowing (1) of Eurodollar Loans shall be not less than $500,000 and shall
be in an integral multiple of $500,000, and (2) of Base Rate Loans hereunder
shall be not less than $500,000 and shall be in an integral multiple of

Amount in effect at such time. Borrowings of more than one Type may be
outstanding at the same time; PROVIDED, HOWEVER, that the Company shall not be
entitled to request any Borrowing that, if made, would result in an aggregate of
more than five (5) separate Borrowings of Eurodollar Loans being outstanding at
any one time. For purposes of the foregoing, Borrowings having different
Interest Periods, regardless of whether they commence on the same date, shall be
considered separate Borrowings.

      Section    2.2    BORROWING REQUESTS.

            (b) NOTICE BY ADMINISTRATIVE AGENT. The Administrative Agent shall
promptly give each Lender telecopy or telephonic notice (and, in the case of
telephonic notices, confirmed by telecopy or otherwise in writing) of the
proposed Borrowing, of such Lender's Applicable Percentage thereof and of the
other matters covered by the Advance Notice. The Company hereby waives the right
to dispute the Administrative Agent's record of the terms of such telephonic
notice, absent manifest error.

      Section    2.3    LETTERS OF CREDIT.

            (a) ISSUANCE OF LETTERS OF CREDIT. Subject to the terms and
conditions hereof, the Company shall have the right, in addition to Revolving
Credit Loans provided for in Section 2.1, to utilize the Revolving Credit
Commitments from time to time prior to the Revolving Credit Maturity Date by
obtaining the issuance of either Documentary Letters of Credit or Standby
Letters of Credit for the account of the Company by the Issuing Bank if the
Company shall so request in the notice referred to in Section 2.3(b)(1) (such
letters of credit being collectively referred to as the "LETTERS OF CREDIT");
PROVIDED, HOWEVER, that the Aggregate Revolving Credit Exposure at any one time
outstanding shall not exceed the Maximum Available Amount in effect at such time
and the aggregate of all Letter of Credit Liabilities at any one time
outstanding shall not exceed $5,000,000. The Letters of Credit shall be
denominated in Dollars and may be issued to support the obligations of the
Company or any of its Subsidiaries. Upon the date of the issuance of a Letter of
Credit, the Issuing Bank shall be deemed, without further action by any party
hereto, to have sold to each Lender, and each Lender shall be deemed, without
further action by any party hereto, to have purchased from the Issuing Bank, a
participation, to the extent of such Lender's Revolving Credit Percentage, in
such Letter of Credit and the related Letter of Credit Liabilities. No Letter of
Credit issued pursuant to this Agreement shall have an expiry date beyond the
earlier of one year after the date of issuance or five days prior to the
Revolving Credit Maturity Date. Any Letter of Credit may give the beneficiary
thereof either the right to draw upon the Letter of Credit upon its expiry date
or the right to automatically extend the expiry date thereof for periods of up
to one year per extension; PROVIDED that no such extension shall extend the
expiry date beyond five days prior to the Revolving Credit Maturity Date.

            (b) ADDITIONAL LETTER OF CREDIT PROVISIONS. The following additional
provisions shall apply to each Letter of Credit:

                  (1) The Company shall give the Administrative Agent and the
      Issuing Bank at least three Business Days' prior notice (effective upon
      receipt), or in each case, such shorter period as may be agreed to by the
      Administrative Agent and the Issuing Bank, specifying the date such Letter
      of Credit is to be issued (which shall be a Business Day) and describing:
      (A) the face amount of the Letter of Credit, (B) the expiration date of
      the Letter of Credit, (C) the name and address of the beneficiary, (D)
      information concerning the transaction proposed to be supported by such
      Letter of Credit as the Administrative Agent or the Issuing Bank may
      reasonably request, (E) such other information and documents relating to
      the Letter of Credit as the Administrative Agent or the Issuing Bank may
      reasonably request, and (F) a precise description of documents and the
      verbatim text of any certificate to be presented by the beneficiary,
      which, if presented prior to the expiry date of the Letter of Credit,
      would require the Issuing Bank to make payment under the Letter of Credit;
      PROVIDED that the Issuing Bank, in its reasonable judgment, may require
      changes in such documents and certificates; and PROVIDED FURTHER that the
      Issuing Bank shall not be required to issue any Letter of Credit that on
      its terms requires payment thereunder prior to the next Business Day
      following receipt by the Issuing Bank of such documents and certificates.
      Each such notice shall be accompanied by the Issuing Bank's Application
      and by a certificate executed by a Responsible Officer setting forth
      calculations evidencing availability for such Letter of Credit pursuant to
      Section 2.3(b)(2) and stating that all conditions precedent to such
      issuance have been satisfied. Each Letter of Credit shall, to the extent
      not inconsistent with the express terms hereof or the applicable


                                       19
<PAGE>
      Application, be subject to, as applicable, either the Uniform Customs and
      Practice for Documentary Credits (1993 Revision), International Chamber of
      Commerce Publication No. 500 or International Standby Practices (ISP98)
      International Chamber of Commerce Publication No. 590 (together with any
      subsequent revisions thereof approved by a Congress of the International
      Chamber of Commerce, the "UCP"), and shall, as to matters not governed by
      the UCP, be governed by, and construed and interpreted in accordance with,
      the laws of the State of Texas.

                  (2) No Letter of Credit may be issued if after giving effect
      thereto the Aggregate Revolving Credit Exposure would exceed the Maximum
      Available Amount. On each day during the period commencing with the
      issuance of any Letter of Credit and until such Letter of Credit shall
      have expired or have been terminated, the Revolving Credit Commitment of
      each Lender shall be deemed to be utilized for all purposes hereof in an
      amount equal to such Lender's Revolving Credit Percentage of the amount of
      the Letter of Credit Liabilities related to such Letter of Credit.

                  (3) Upon receipt from the beneficiary of any Letter of Credit
      of any demand for payment thereunder, the Issuing Bank shall promptly
      notify the Company and the Administrative Agent of such demand (provided
      that the failure of the Issuing Bank to give such notice shall not affect
      the Reimbursement Obligations of the Company hereunder) and the Company
      shall immediately, and in any event no later than 10:00 a.m. (Houston,
      Texas time) on the date of such drawing, reimburse the Administrative
      Agent for the account of the Issuing Bank for any amount paid by the
      Issuing Bank upon any drawing under any Letter of Credit, without
      presentment, demand, protest or other formalities of any kind in an
      amount, in same day funds, equal to the amount of such drawing. Unless
      prior to 10:00 a.m. (Houston, Texas time) on the date of such drawing, the
      Company shall have either notified the Issuing Bank and the Administrative
      Agent that the Company intends to reimburse the Administrative Agent for
      the account of the Issuing Bank for the amount of such drawing with funds
      other than the proceeds of Revolving Credit Loans or delivered to the
      Administrative Agent a Borrowing Request for Revolving Credit Loans in an
      amount equal to such drawing, the Company will be deemed to have given a
      Borrowing Request to the Administrative Agent requesting that the Lenders
      make Revolving Credit Loans which shall be Base Rate Loans on the date on
      which such drawing is honored in an amount equal to the amount of such
      drawing; PROVIDED THAT such Loans shall be subject to (A) the satisfaction
      of the conditions in Article 3 and (B) the existence of Revolving Credit
      Loan availability pursuant to Section 2.1(c) hereof (after giving effect
      to repayment of the applicable Reimbursement Obligations with the proceeds
      of the proposed Revolving Credit Loans). Subject to the preceding
      sentence, if so requested by the Administrative Agent, each of the Lenders
      shall, on the date of such drawing, make such Revolving Credit Loans in an
      amount equal to such Lender's Revolving Credit Percentage of such drawing
      or the full amount of the unused Revolving Credit Loan available pursuant
      to Section 2.1(c), as applicable, the proceeds of which shall be applied
      directly by the Administrative Agent to reimburse the Issuing Bank to the
      extent of such proceeds.

                  (4) If the Company fails to reimburse the Issuing Bank as
      provided in clause (3) above for any reason, including, but not limited
      to, failure to satisfy the conditions in Article 3 or insufficient unused
      Revolving Credit Loan availability pursuant to Section 2.1(c), the Issuing
      Bank shall promptly notify the Administrative Agent and the Administrative
      Agent shall notify each Lender of the unreimbursed amount of such drawing
      and of such Lender's respective participation therein based on such
      Lender's Revolving Credit Percentage. Each Lender will pay to the
      Administrative Agent for the account of the Issuing Bank on the date of
      such notice an amount equal to such Lender's Revolving Credit Percentage
      of such unreimbursed drawing (or, if such notice is made after 1:00 p.m.
      (Houston, Texas time) on such date, on the next succeeding Business Day).
      If any Lender fails to make available to the Issuing Bank the amount of
      such Lender's participation 

                                       20
<PAGE>
      in such Letter of Credit as provided in this clause (4), the Issuing Bank
      shall be entitled to recover such amount on demand from such Lender
      together with interest at the Federal Funds Effective Rate for one
      Business Day and thereafter at the Base Rate. Nothing in this clause (4)
      shall be deemed to prejudice the right of any Lender to recover from the
      Issuing Bank any amounts made available by such Lender to the Issuing Bank
      pursuant to this clause (4) if it is determined by a court of competent
      jurisdiction that the payment with respect to a Letter of Credit by the
      Issuing Bank was wrongful and such wrongful payment was the result of
      gross negligence or willful misconduct on the part of the Issuing Bank.
      The Issuing Bank shall pay to the Administrative Agent and the
      Administrative Agent to each Lender such Lender's Revolving Credit
      Percentage of all amounts received from the Company for payment, in whole
      or in part, of the Reimbursement Obligation in respect of any Letter of
      Credit, but only to the extent such Lender has made payment to the Issuing
      Bank in respect of such Letter of Credit pursuant to this clause (4).

                  (5) The issuance by the Issuing Bank of each Letter of Credit
      shall, in addition to the conditions precedent set forth in Article 3, be
      subject to the conditions precedent that such Letter of Credit shall be in
      the form and contain such terms as shall be reasonably satisfactory to the
      Issuing Bank, and that the Company shall have executed and delivered such
      other instruments and agreements relating to the Letter of Credit as the
      Issuing Bank shall have reasonably requested and that are not inconsistent
      with the terms of this Agreement including the Issuing Bank's Application
      therefor. In the event of a conflict between the terms of this Agreement
      and the terms of any Application, the terms of this Agreement shall
      control.

                  (6) AS BETWEEN THE COMPANY AND THE ISSUING BANK, THE COMPANY
      ASSUMES ALL RISKS OF THE ACTS AND OMISSIONS OF OR MISUSE OF THE LETTERS OF
      CREDIT ISSUED BY THE ISSUING BANK BY THE RESPECTIVE BENEFICIARIES OF SUCH
      LETTERS OF CREDIT. IN FURTHERANCE AND NOT IN LIMITATION OF THE FOREGOING,
      THE ISSUING BANK SHALL NOT BE RESPONSIBLE: (A) FOR THE FORM, VALIDITY,
      SUFFICIENCY, ACCURACY, GENUINENESS OR LEGAL EFFECT OF ANY DOCUMENT
      SUBMITTED BY ANY PERSON IN CONNECTION WITH THE APPLICATION FOR OR ISSUANCE
      OF SUCH LETTERS OF CREDIT, EVEN IF IT SHOULD IN FACT PROVE TO BE IN ANY OR
      ALL RESPECTS INVALID, INSUFFICIENT, INACCURATE, FRAUDULENT OR FORGED; (B)
      FOR THE VALIDITY OR SUFFICIENCY OF ANY INSTRUMENT TRANSFERRING OR
      ASSIGNING OR PURPORTING TO TRANSFER OR ASSIGN ANY SUCH LETTER OF CREDIT OR
      THE RIGHTS OR BENEFITS THEREUNDER OR PROCEEDS THEREOF, IN WHOLE OR IN
      PART, WHICH MAY PROVE TO BE INVALID OR INEFFECTIVE FOR ANY REASON; (C) FOR
      ERRORS, OMISSIONS, INTERRUPTIONS OR DELAYS IN TRANSMISSION OR DELIVERY OF
      ANY MESSAGES, BY MAIL, CABLE, TELEGRAPH, TELEX OR OTHERWISE, WHETHER OR
      NOT THEY ARE IN CIPHER; (D) FOR ERRORS IN INTERPRETATION OF TECHNICAL
      TERMS; (E) FOR ANY LOSS OR DELAY IN THE TRANSMISSION OR OTHERWISE OF ANY
      DOCUMENT REQUIRED IN ORDER TO MAKE A DRAWING UNDER ANY SUCH LETTER OF
      CREDIT OR OF THE PROCEEDS THEREOF; (F) FOR THE MISAPPLICATION BY THE
      BENEFICIARY OF ANY SUCH LETTER OF CREDIT OF THE PROCEEDS OF ANY DRAWING
      UNDER SUCH LETTER OF CREDIT; AND (G) FOR ANY CONSEQUENCES ARISING FROM
      CAUSES BEYOND THE CONTROL OF THE ISSUING BANK, INCLUDING, WITHOUT
      LIMITATION, THE ACTIONS OF ANY GOVERNMENTAL AUTHORITY. NONE OF THE ABOVE
      SHALL AFFECT, IMPAIR, OR PREVENT THE VESTING OF ANY OF THE ISSUING BANK'S
      RIGHTS OR POWERS HEREUNDER. NOTWITHSTANDING ANYTHING TO THE CONTRARY
      CONTAINED IN THIS CLAUSE (G), THE COMPANY SHALL NOT ASSUME ANY RISK, AND
      SHALL HAVE NO OBLIGATION TO INDEMNIFY THE ISSUING BANK, IN RESPECT OF ANY
      LIABILITY INCURRED BY THE ISSUING BANK ARISING PRIMARILY OUT OF THE GROSS
      NEGLIGENCE OR WILLFUL MISCONDUCT OF THE ISSUING BANK, AS DETERMINED BY A
      COURT OF COMPETENT JURISDICTION.

<PAGE>
                  (7) The Issuing Bank will send to the Company and the
      Administrative Agent immediately upon issuance of any Letter of Credit, or
      an amendment thereto, a true and complete copy of such Letter of Credit,
      or such amendment thereto. Upon issuance of any Letter of Credit or an
      amendment thereto, the Administrative Agent shall promptly notify each
      Lender of the terms of such Letter of Credit or amendment thereto, and of
      such Lender's Revolving Credit Percentage of the amount of such Letter of
      Credit or amendment thereto, and the Administrative Agent shall provide to
      each Lender a copy of such Letter of Credit or such amendment thereto.
      Upon cancellation or termination of any Letter of Credit, the Issuing Bank
      shall promptly notify the Administrative Agent and the Company, and the
      Administrative Agent will then promptly notify each Lender, of such
      cancellation or termination.

                  (8) The obligation of the Company to reimburse the Issuing
      Bank for Reimbursement Obligations with regard to the Letters of Credit
      issued by it and the obligations of the Lenders under clause (4) shall be
      unconditional and irrevocable and shall be paid strictly in accordance
      with the terms of this Agreement and under all circumstances including,
      without limitation, the following circumstances:

                        (A)   any lack of validity or enforceability of any
                              Letter of Credit;

                        (B)   the existence of any claim, set-off, defense or
                              other right that the Company may have at any time
                              against a beneficiary or any transferee of any
                              Letter of Credit (or any Persons for whom any such
                              transferee may be acting), any Lender or any other
                              Person, whether in connection with this Agreement,
                              the transactions contemplated herein or any
                              unrelated transaction (including any underlying
                              transaction between the Company or one of its
                              Subsidiaries and the beneficiary for which the
                              Letter of Credit was procured) other than a
                              defense based on the gross negligence (AS OPPOSED
                              TO ORDINARY NEGLIGENCE) or willful misconduct of
                              the Issuing Bank, as determined by a court of
                              competent jurisdiction;

                        (C)   any draft, demand, certificate or any other
                              document presented under any Letter of Credit is

                              insufficient in any respect or any statement
                              therein is untrue or inaccurate in any respect;

                              result of the gross negligence (AS OPPOSED TO
                              ORDINARY NEGLIGENCE) or willful misconduct of the
                              Issuing Bank, as finally judicially determined by

            (a) AVAILABILITY. No later than 11:00 a.m. (or, in the case of Base
Rate Loans, 1:00 p.m.) (Houston, Texas time) on the date of each Borrowing, each

Loans (if any) of such Lender maturing on such date, in Dollars and in
immediately available funds at the Payment Office. The Administrative Agent will
make available to the Company at the Payment Office the aggregate of the amounts
(if any) so made available by the Lenders by depositing such amounts, in
immediately available funds, to an account of the Company at the Administrative
Agent designated by the Company for such purpose. To the extent that Revolving
Credit Loans mature or Reimbursement Obligations are due and owing on the date
of a requested Borrowing of Revolving Credit Loans, the Lenders shall apply the
proceeds of the Revolving Credit Loans then being made, to the extent thereof,
to the repayment of such maturing Revolving Credit Loans or Reimbursement
Obligations, such Revolving Credit Loans or Reimbursement Obligations and
repayments intended to be a contemporaneous exchange.

            (b) FUNDS TO THE ADMINISTRATIVE AGENT. Unless the Administrative
Agent shall have been notified by any Lender prior to the date of a Borrowing
that such Lender does not intend to make available to the Administrative Agent
such Lender's Applicable Percentage of the Borrowing to be made on such date,
the Administrative Agent may assume that such Lender has made such amount
available to the Administrative Agent on such date, and the Administrative Agent
may make available to the Company a corresponding amount. If such corresponding
amount is not in fact made available to the Administrative Agent by such Lender
on the date of a Borrowing, the Administrative Agent shall be entitled to
recover such corresponding amount on demand from such Lender together with
interest at the Federal Funds Effective Rate. If such Lender does not pay such
corresponding amount forthwith upon the Administrative Agent's demand therefor,
the Administrative Agent shall promptly notify the Company, and the Company
shall immediately pay such corresponding amount to the Administrative Agent
together with interest at the rate specified for the Borrowing which includes
such amount paid. Nothing in this Section shall be deemed to relieve any Lender
from its obligation to fulfill its Commitments hereunder or to prejudice any
rights which the Company may have against any Lender as a result of any default
by such Lender hereunder.

            (c) LENDERS' RESPONSIBILITIES. No Lender shall be responsible for
any default by any other Lender in its obligation to make Loans hereunder, and
each Lender shall be obligated to make only such Loans provided to be made by it
hereunder, regardless of the failure of any other Lender to fulfill its
Commitment hereunder.

      Section    2.5    NOTES AND AMORTIZATION.

            (a) REVOLVING CREDIT NOTES. The Company's obligation to pay the
principal of, and interest on, the Revolving Credit Loans made by each Lender
shall be further evidenced by the Company's issuance, execution and delivery of
a Revolving Credit Note payable to the order of each such Lender in the amount
of such Lender's Revolving Credit Commitment and shall be dated as of the date
of issuance of such Revolving Credit Note. The principal amount of each
Revolving Credit Note shall be payable on or before the Revolving Credit
Maturity Date.

            (b) TERM NOTES AND AMORTIZATION. The Company's obligation to pay the
principal of, and interest on, the Term Loans maintained outstanding by each
Lender has been evidenced by the Company's issuance, execution and delivery of a
Term Note payable to the order of each such Lender in the 

                                       23

amount of such Lender's Term Loan Commitment (if issued prior to February 23,
1998) or in the principal amount of such Lender's Term Loans (if issued after
February 23, 1998), and dated as of the date of issuance of such Term Note. The
aggregate principal amount of the Term Notes applicable to the aggregate Term
Loans of all Lenders shall be payable in quarterly installments of the amounts
set forth below:

                 December 31, 2002                         $2,000,000
                 March 31, 2003                  the aggregate unpaid
                                              principal balance owing
                                                 under the Term Notes.

The first such quarterly installment shall be payable on June 30, 1998, and the

      Section    2.6    INTEREST.  In all cases subject to Section 9.13:

            (a) BASE RATE LOANS. Subject to Section 2.6(c), the Company agrees
to pay interest in respect of the unpaid principal amount of each Base Rate Loan
from the date thereof until payment in full thereof at a rate per annum which
shall be, for any day, equal to the sum of the Applicable Margin plus the Base
Rate in effect on such day, but in no event to exceed the Highest Lawful Rate.
The term "BASE RATE" shall mean, for any day, the highest of (1) the Prime Rate
in effect on such day, and (2) one-half of one percent (1/2%) plus the Federal
Funds Effective Rate in effect for such day (rounded upwards, if necessary, to
the nearest 1/16th of 1%), but in no event to exceed the Highest Lawful Rate.
For purposes of this Agreement, any change in the Base Rate due to a change in
the Federal Funds Effective Rate or the Prime Rate shall be effective as of the
opening of business on the effective date of such change in the Federal Funds
Effective Rate or the Prime Rate, as the case may be. If for any reason the
Administrative Agent shall have determined (which determination shall be
conclusive and binding, absent manifest error) that it is unable to ascertain
the Federal Funds Effective Rate for any reason, including but not limited to
the inability of the Administrative Agent to obtain sufficient bids or
publications in accordance with the terms hereof, the Base Rate shall be the
Prime Rate until the circumstances giving rise to such inability no longer
exist.


                                       24
<PAGE>
            (b) EURODOLLAR LOANS. Subject to Section 2.6(c), the Company agrees
to pay interest in respect of the unpaid principal amount of each Eurodollar
Loan from the date thereof until payment in full thereof at a rate per annum
which shall be the sum of the relevant Applicable Margin plus the Eurodollar
Rate, but in no event to exceed the Highest Lawful Rate.

            (c) DEFAULT INTEREST. If the Company shall default in the payment of
the principal of or interest on any Loan or any other amount becoming due
hereunder or under any Financing Document, by acceleration or otherwise, the
Company shall on demand from time to time pay interest, to the extent permitted
by law, on such defaulted amount to but excluding the date of actual payment
(after as well as before judgment) at a rate per annum equal to (1) in the case
of any Eurodollar Loan, the rate that would be applicable under Section 2.6(b)
to such Eurodollar Loan, plus 2% per annum, and (2) in the case of any other
amount, the rate that would be applicable under Section 2.6(a) to a Base Rate
Loan, plus 2% per annum, but in no event to exceed the Highest Lawful Rate.

            (d) INTEREST PAYMENT DATES. Interest on each Loan shall accrue from
and including the date of such Loan to but excluding the date of payment in full
thereof. Interest on each Eurodollar Loan shall be payable on the last day of
each Interest Period applicable thereto and, in the case of an Interest Period
in excess of three months, on each day which occurs every three months after the
initial date of such Interest Period, and on any prepayment (on the amount
prepaid), at maturity (whether by acceleration or otherwise) and, after
maturity, on demand. Interest on each Base Rate Loan shall be payable on each
Quarterly Date, commencing on the first of such days to occur after such Loan is
made, at maturity (whether by acceleration or otherwise) and, after maturity, on
demand.

            (e) NOTICE BY THE ADMINISTRATIVE AGENT. The Administrative Agent,
upon determining the Eurodollar Rate for any Interest Period, shall promptly
notify by telecopy or telephone (in the case of telephonic notices, confirmed by
telecopy or otherwise in writing) or in writing the Company and the Lenders.

      Section 2.7 INTEREST PERIODS. In connection with each Borrowing of
Eurodollar Loans, the Company shall elect an Interest Period to be applicable to
such Borrowing, which Interest Period shall begin on and include, as the case
may be, the date selected by the Company pursuant to Section 2.2(a), the
conversion date or the date of expiration of the then current Interest Period
applicable thereto, and end on but exclude the date which is either one, two,
three or six months thereafter, as selected by the Company; PROVIDED that:

            (a) BUSINESS DAYS. If any Interest Period would otherwise expire on
a day which is not a Business Day, such Interest Period shall expire on the next
succeeding Business Day, PROVIDED, FURTHER, that if any Interest Period (other
than in respect of a Borrowing of Eurodollar Loans the Interest Period of which
is expiring pursuant to Section 2.15(b) hereof) would otherwise expire on a day
which is not a Business Day but is a day of the month after which no further
Business Day occurs in such month, such Interest Period shall expire on the next
preceding Business Day;

            (b) MONTH END. Any Interest Period which begins on the last Business
Day of a calendar month (or on a day for which there is no numerically
corresponding day in the calendar month at the end of such Interest Period)
shall, subject to Section (c) below, end on the last Business Day of a calendar
month;

            (c) PAYMENT LIMITATIONS. No Interest Period shall extend beyond any
date that any principal payment or prepayment is scheduled to be due unless the
aggregate principal amount of Borrowings which are Borrowings of Base Rate Loans
or which have Interest Periods which will expire on or before such 

                                       25
<PAGE>
date, less the aggregate amount of any other principal payments or prepayments
due during such Interest Period, is equal to or in excess of the amount of such
principal payment or prepayment; and

            (d) MATURITY DATES. No Interest Period with regard to Revolving
Credit Loans shall extend beyond the Revolving Credit Maturity Date and no
Interest Period with regard to Term Loans shall extend beyond the Term Loan
Maturity Date.

      Section    2.8    REPAYMENT OF LOANS.

            (a) The Company hereby unconditionally promises to pay to the
Administrative Agent for the account of each Lender (1), the then unpaid
principal amount of each Revolving Credit Loan of such Lender on the Revolving
Credit Maturity Date (or such earlier date on which the Revolving Credit Loans
become due and payable pursuant to Article 7); and (2) the amounts specified in
Section 2.5(b), on the dates specified in Section 2.5(b) (or such earlier date
on which the Term Loans become due and payable pursuant to Article 7). The
Company hereby further agrees to pay interest on the unpaid principal amount of
the Loans from time to time outstanding from the date hereof until payment in
full thereof at the rates per annum, and on the dates, set forth in Section 2.6.

            (b) Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing indebtedness of the Company to such Lender
resulting from each Loan of such Lender from time to time, including, without
limitation, the amounts of principal and interest payable and paid to such
Lender from time to time under this Agreement.

            (c) The Administrative Agent shall maintain the Register pursuant to
Section 9.7(d), and a subaccount therein for each Lender, in which shall be
recorded (1) the amount of each Loan made hereunder, the Type thereof and each
Interest Period, if any, applicable thereto, (2) the amount of any principal or
interest due and payable or to become due and payable from the Company to each
Lender hereunder and (3) both the amount of any sum received by the
Administrative Agent hereunder from the Company and each Lender's Applicable
Percentage thereof.

            (d) The entries made in the Register and the accounts of each Lender
maintained pursuant to Section 2.8(c) shall, to the extent permitted by
applicable law, be PRIMA FACIE evidence of the existence and amounts of the
obligations of the Company therein recorded; PROVIDED, HOWEVER, that the failure
of any Lender or the Administrative Agent to maintain the Register or any such
account, or any error therein, shall not in any manner affect the obligation of
the Company to repay (with applicable interest) the Loans made to the Company by
such Lender in accordance with the terms of this Agreement.

      Section 2.9 VOLUNTARY TERMINATION OR REDUCTION OF COMMITMENTS. The Company
may, upon at least three (3) Business Days' notice to the Administrative Agent,
terminate entirely at any time, or partially reduce from time to time by an
aggregate amount of $5,000,000 or any larger multiple of $5,000,000, the unused
portions of the Revolving Credit Commitments, provided that any such reduction
shall apply proportionately to the Revolving Credit Commitment of each Lender.
If the Revolving Credit Commitments are terminated in their entirety, all
accrued commitment fees with respect thereto shall be payable on the effective
date of such termination.

                                       26
<PAGE>
      Section    2.10   PREPAYMENTS AND MANDATORY COMMITMENT REDUCTIONS.

            (a) MANDATORY PREPAYMENTS AND COMMITMENT REDUCTIONS. If at any time
the Aggregate Revolving Credit Exposure is in excess of the Maximum Available
Amount, the Company shall immediately pay to the Administrative Agent, for the
account of the Lenders, the amount of such excess to be applied (A) as a
prepayment of the Revolving Credit Loans and Reimbursement Obligations
outstanding and (B) after payment in full of the Revolving Credit Loans and
Reimbursement Obligations outstanding, as Cover for the Letter of Credit
Liabilities in an amount of such remaining excess. Any such prepayment or Cover
resulting from a termination or reduction of the Commitments pursuant to Section
2.9, shall be payable or provided in full on the date on which such reduction or
termination of the Commitments becomes effective.


            (b) VOLUNTARY PREPAYMENTS. The Company may, at its option, at any
time and from time to time, prepay the Loans and the Reimbursement Obligations,
in whole or in part, upon giving, in the case of any Eurodollar Loan, three
Business Days' prior written notice to the Administrative Agent, and, in the
case of any Base Rate Loan, prior written notice on the same Business Day to the
Administrative Agent. Such notice shall specify (1) in the case of any
prepayment of Loans, the date and amount of prepayment and whether the
prepayment is (A) of Term Loans or Revolving Credit Loans, or a combination
thereof and (B) of Eurodollar Loans, Base Rate Loans or a combination thereof,
and, in each case if a combination thereof, the principal amount allocable to
each; and (2) in the case of any prepayment of Reimbursement Obligations, the
date and amount of prepayment, the identity of the applicable Letter of Credit
or Letters of Credit and the amount allocable to each of such Reimbursement
Obligations. Upon receipt of such notice, the Administrative Agent shall
promptly notify each Lender of the contents thereof and of such Lender's
Applicable Percentage of such prepayment. If any such notice is given, the
amount specified in such notice shall be due and payable on the date specified
therein, together with (if a Eurodollar Loan is prepaid other than at the end of
the Interest Period applicable thereto) any amounts payable pursuant to Section
2.18 and, in the case of prepayments of the Term Loans only, accrued interest to
such date on the amount prepaid. Prepayments of (A) the Term Loans pursuant to
this Section 2.10(b) shall be applied ratably to the remaining scheduled
installment payments of the Term Loans required pursuant to Section 2.5(b); and
(B) the Revolving Credit Loans and the Reimbursement Obligations pursuant this
Section shall (unless the Company otherwise directs) be applied, FIRST, to
payment of the Revolving Credit Loans then outstanding, SECOND, to payment of
any Reimbursement Obligations then outstanding and, LAST, to Cover any
outstanding Letter of Credit Liability. Each prepayment of Base Rate Loans shall
be in the minimum principal amount of $500,000 and in integral multiples of
$500,000 and each prepayment of Eurodollar Loans shall be in the minimum
principal amount of $500,000 and in integral multiples of $500,000 or, in the
case of either Base Rate Loans or Eurodollar Loans, the aggregate principal
balance outstanding on the Term Loans or on the Revolving Credit Loans and the
Reimbursement Obligations, as applicable.

            (c) NOTICE BY ADMINISTRATIVE AGENT. Upon receipt of a notice of
prepayment pursuant to this Section, the Administrative Agent shall promptly
notify each Lender of the contents thereof and of such Lender's ratable share of
such prepayment.


      Section    2.11   CONTINUATION AND CONVERSION OPTIONS.

            (a) CONTINUATION. The Company may elect to continue all or any part
of any Borrowing of Eurodollar Loans beyond the expiration of the then current
Interest Period relating thereto by giving Advance Notice (which shall be
irrevocable) to the Administrative Agent of such election, specifying the
Eurodollar Loans or portion thereof to be continued and the Interest Period
therefor. In the absence of such a timely and proper election with regard to
Eurodollar Loans, the Company shall be deemed to have elected to convert such
Eurodollar Loans to Base Rate Loans pursuant to Section 2.11(d).


                                       27
<PAGE>
            (b) AMOUNT OF CONTINUATIONS. All or part of any Eurodollar Loans may
be continued as provided herein, provided that any continuation of such Loans
shall not be (as to each Borrowing of such Loans as continued for an applicable
Interest Period) less than $500,000 and shall be in an integral multiple of
$500,000.

            (c) CONTINUATION OR CONVERSION UPON DEFAULT. If no Default shall
have occurred and be continuing, each Eurodollar Loan may be continued or
converted as provided in this Section. If a Default shall have occurred and be
continuing, the Company shall not have the option to elect to continue any such
Eurodollar Loan pursuant to Section 2.11(a) or to convert Base Rate Loans to
Eurodollar Loans pursuant to Section 2.11(e).

            (d) CONVERSION TO BASE RATE. The Company may elect to convert any
Eurodollar Loan on the last day of the then current Interest Period relating
thereto to a Base Rate Loan by giving Advance Notice to the Administrative Agent
of such election.

            (e) CONVERSION TO EURODOLLAR RATE. The Company may elect to convert
any Base Rate Loan at any time or from time to time to a Eurodollar Loan by
giving Advance Notice (which shall be irrevocable) to the Administrative Agent
of such election, specifying each Interest Period therefor.

            (f) AMOUNTS OF CONVERSIONS. All or any part of the outstanding Loans
may be converted as provided herein, provided that any conversion of such Loans
shall not result in a Borrowing of Eurodollar Loans in an amount less than
$500,000 and in integral multiples of $500,000.

      Section    2.12   FEES.

            (a) REVOLVING CREDIT COMMITMENTS. The Company shall pay to the
Administrative Agent for the account of and distribution to each Lender in
accordance with its Revolving Credit Percentage a commitment fee for the period
commencing on the Closing Date, to and including the Revolving Credit Maturity
Date (or such earlier date as the Revolving Credit Commitments shall have been
terminated entirely) computed at a rate per annum equal to the Applicable
Commitment Fee Percentage on the average daily excess amount of the Revolving
Credit Commitments over the Revolving Credit Exposure. The commitment fees on
the Revolving Credit Commitments earned from and after the Closing Date shall be
payable in arrears on each Quarterly Date, commencing on the first Quarterly
Date to occur after the Closing Date.

            (b) LETTERS OF CREDIT.

                  (1) As consideration for acting as the Issuing Bank with
      respect to any Letter of Credit, the Company will pay to the Issuing Bank
      a fee computed at a rate per annum equal to 1/8% of 1% on the daily
      average amount available for drawing on the applicable Letter of Credit,
      payable in arrears on each Quarterly Date. The Company shall also pay to
      the Issuing Bank, with respect to any issuance, amendment, transfer, or
      cancellation prior to expiration of any Letter of Credit and for each
      drawing made thereunder, documentary and processing charges in accordance
      with the Issuing Bank's standard schedule for such charges in effect at
      the time of, and payable at the time of, such issuance, amendment,
      transfer, cancellation or drawing, as the case may be. All fees payable
      pursuant to this clause (1) shall be retained by the Issuing Bank.

                  (2) The Company will pay to the Administrative Agent for the
      account of and pro rata distribution to each Lender a fee on the daily
      average amount available for drawings under each Letter of Credit, in each
      case for the period from and including the date of issuance of such Letter
      of Credit to and excluding the date of expiration or termination thereof
      computed at a per 

                                       28
<PAGE>
      annum rate for each day equal to the greater of $500 or the Applicable
      Margin for Revolving Credit Loans that are Eurodollar Loans multiplied by
      the amount of the Letter of Credit. Such fees shall be payable in arrears
      on each Quarterly Date.

            (c) FEE LETTER. The Company shall pay to the Administrative Agent
and to Arranger such fees as are set forth in the Fee Letter, as the same has
been or may be hereafter amended or supplemented, on the dates and in the manner
specified therein.

      Section    2.13   PAYMENTS, ETC.

            (a) WITHOUT SETOFF, ETC. Except as otherwise specifically provided
herein, all payments under this Agreement shall be made to the Administrative
Agent for the account of the Lenders without defense, set-off or counterclaim to
the Administrative Agent not later than 11:00 a.m. Houston, Texas time on the
date when due and shall be made in Dollars in immediately available funds at the
Payment Office. The Administrative Agent will promptly thereafter distribute
funds in the form received relating to the payment of principal or interest or
commitment fees ratably to the Lenders for the account of their respective
Lending Offices, and funds in the form received relating to the payment of any
other amount payable to any Lender to such Lender for the account of its
applicable Lending Office.

            (b) NON-BUSINESS DAYS. Whenever any payment to be made hereunder or
under any Note shall be stated to be due on a day which is not a Business Day,
the due date thereof shall be extended to the next succeeding Business Day
(except as otherwise provided in Section 2.7 hereof) and, with respect to
payments of principal, interest thereon shall be payable at the applicable rate
during such extension.

            (c) COMPUTATIONS. All computations of interest shall be made on the
basis of a year of 360 days (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) in the case of Eurodollar Loans or Base Rate
Loans that are based upon the Federal Funds Effective Rate, and 365 or 366 days
(as the case may be) in the case of Base Rate Loans that are based upon the
Prime Rate, and all computations of fees shall be made on the basis of a year of
360 days (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), in each case for the actual number of days (including the first
day but excluding the last day) occurring in the period for which such interest
or fees are payable. Each determination by the Administrative Agent of an
interest rate or fee hereunder shall, except for manifest error, be final,
conclusive and binding for all purposes, provided that such determination shall
be made in good faith in a manner generally consistent with the Administrative
Agent's standard practice. If the Administrative Agent and the Company determine
that manifest error exists, said parties shall correct such error by way of an
adjustment to the payment due on the next Quarterly Date.

            Section 2.14 INTEREST RATE NOT ASCERTAINABLE, ETC. In the event that
the Administrative Agent shall have determined (which determination shall be
reasonably exercised and shall, absent manifest error, be final, conclusive and
binding upon all parties) that on any date for determining the Eurodollar Rate
for any Interest Period, by reason of any changes arising after the date of this
Agreement affecting the interbank Eurodollar market, or any Lender's position in
such market, adequate and fair means do not exist for ascertaining the
applicable interest rate on the basis provided for in the definition of
Eurodollar Rate, then, and in any such event, the Administrative Agent shall
forthwith give notice (by telephone confirmed in writing) to the Company and to
the Lenders of such determination. Until the Administrative Agent notifies the
Company that the circumstances giving rise to the suspension described herein no
longer exist, the obligations of the Lenders to make Eurodollar Loans shall be
immediately suspended; any Borrowing of Eurodollar Loans that is requested (by
continuation, conversion or otherwise) shall instead be made as a 

                                       29
<PAGE>
Borrowing of Base Rate Loans, and any outstanding Eurodollar Loan shall be
converted, on the last day of the then current Interest Period applicable
thereto, to a Base Rate Loan.

      Section    2.15   ILLEGALITY.

            (a) DETERMINATIONS OF ILLEGALITY. In the event that any Lender shall
have determined (which determination shall be reasonably exercised and shall,
absent manifest error, be final, conclusive and binding upon all parties) at any
time that the making or continuance of any Eurodollar Loan has become unlawful
as a result of compliance by such Lender in good faith with any applicable law,
governmental rule, regulation, guideline or order (whether or not having the
force of law and whether or not failure to comply therewith would be unlawful),
then, in any such event, the Lender shall give prompt notice (by telephone
confirmed in writing) to the Company and to the Administrative Agent of such
determination (which notice the Administrative Agent shall promptly transmit to
the other Lenders).

            (b) EURODOLLAR LOANS SUSPENDED. Upon the giving of the notice to the
Company referred to in Section 2.15(a) above, (1) the Company's right to request
(by continuation, conversion or otherwise) and such Lender's obligation to make
Eurodollar Loans shall be immediately suspended, and thereafter, any requested
Borrowing of Eurodollar Loans shall, as to such Lender only, be deemed to be a
request for a Base Rate Loan, and (2) if the affected Eurodollar Loan or Loans
are then outstanding, the Company shall immediately, or if permitted by
applicable law, no later than the date permitted thereby, upon at least one
Business Day's written notice to the Administrative Agent and the affected
Lender, convert each such Eurodollar Loan into a Base Rate Loan, provided that
if more than one Lender is affected at any time, then all affected Lenders must
be treated the same pursuant to this subsection.

      Section    2.16   INCREASED COSTS.

            (a) EURODOLLAR REGULATIONS, ETC. If, by reason of (x) the
introduction of or any change (including, but not limited to, any change by way
of imposition or increase of reserve requirements) in or in the interpretation
of any law or regulation, or (y) the compliance with any guideline or request
issued by any central bank or other governmental authority or quasi-governmental
authority exercising control over banks or financial institutions generally
(whether or not having the force of law):

                  (1) any Lender (or its applicable Lending Office) shall be
      subject to any tax, duty or other charge with respect to its Eurodollar
      Loans or its obligation to make Eurodollar Loans, or shall change the
      basis of taxation of payments to any Lender of the principal of or
      interest on its Eurodollar Loans or its obligation to make Eurodollar
      Loans (except for changes in the rate of tax on the overall net income or
      gross receipts of such Lender or its applicable Lending Office imposed by
      the jurisdiction in which such Lender's principal executive office or
      applicable Lending Office is located); or

                  (2) any reserve (including, but not limited to, any imposed by
      the Board of Governors of the Federal Reserve System, but excluding any
      such reserve requirement that is reflected in the Eurodollar Rate),
      special deposit or similar requirement against assets of, deposits with or
      for the account of, or credit extended by, any Lender or its applicable
      Lending Office shall be imposed or deemed applicable or any other
      condition affecting its Eurodollar Loans or its obligations to make
      Eurodollar Loans shall be imposed on any Lender or its applicable Lending
      Office or the interbank Eurodollar market or the secondary certificate of
      deposit market;

and as a result thereof there shall be any increase in the cost to such Lender
of agreeing to make or making, funding or maintaining Eurodollar Loans (except
to the extent already included in the determination of the 

                                       30
<PAGE>
applicable Eurodollar Rate) or there shall be a reduction in the amount received
or receivable by such Lender or its applicable Lending Office, then the Company
shall from time to time, upon written notice from and demand by such Lender
(with a copy of such notice and demand to the Administrative Agent), pay to such
Lender on demand additional amounts determined by such Lender in a reasonable
manner to be sufficient to indemnify such Lender against such increased cost. A
certificate as to the amount of such increased cost and the calculation thereof,
submitted to the Company and the Administrative Agent by such Lender, shall,
except for manifest error, be final, conclusive and binding for all purposes.

            (b) COSTS. If any Lender shall advise the Administrative Agent that
at any time, because of the circumstances described in clauses (x) or (y) in
Section 2.16(a) or any other circumstances affecting such Lender or the
interbank Eurodollar market or such Lender's position in such market, the
Eurodollar Rate, as determined in good faith by the Administrative Agent, will
not adequately and fairly reflect the cost to such Lender of funding its
Eurodollar Loans, then, and in any such event:

                  (1) the Administrative Agent shall forthwith give notice (by
      telephone confirmed in writing) to the Company and to the Lenders of such
      advice;

                  (2) the Company's right to request a Borrowing of Eurodollar
      Loans from such Lender and such Lender's obligation to make Eurodollar
      Loans shall be immediately suspended, any such Borrowing of Eurodollar
      Loans that is requested (by continuation, conversion or otherwise) shall,
      as to such Lender only, be deemed to be a request for a Base Rate Loan,
      and any such outstanding Eurodollar Loan from such Lender shall be
      converted, on the last day of the then current Interest Period applicable
      thereto, to a Base Rate Loan.

            (c) CAPITAL ADEQUACY. If, by reason of (1) the introduction of or
any change (including, but not limited to, any change by way of imposition or
increase of reserve requirements) in or in the interpretation of any law or
regulation, or (2) the compliance with any guideline or request issued by any
central bank or other governmental authority or quasi-governmental authority
exercising control over banks or financial institutions generally (whether or
not having the force of law), affects or would affect the amount of capital
required to be maintained by any Lender or any corporation controlling such
Lender, and the amount of such capital is increased by or based upon the
existence of such Lender's Loans or such Lender's commitment to lend hereunder
and other commitments of this type or of the Letters of Credit (or similar
contingent obligations), then, upon written request therefor by such Lender
(with a copy of such request to the Administrative Agent), the Company shall pay
to such Lender, from time to time as specified by such Lender, additional
amounts sufficient to compensate such Lender for the increased cost of such
additional capital in light of such circumstances, to the extent that such
Lender reasonably determines such increase in capital to be allocable to the
existence of such Lender's Loans or such Lender's commitment to lend hereunder
or to the issuance or maintenance of the Letters of Credit. A certificate as to
such amounts and the calculation thereof, submitted to the Company and the
Administrative Agent by such Lender, shall be conclusive and binding for all
purposes, absent manifest error.

            (d) ISSUING BANK. The rights and benefits of the Lenders under this
Section 2.16 shall also apply to the Issuing Bank in its capacity as such.

            (e) TIME LIMIT. The Company shall not compensate any Lender or the
Administrative Agent for any costs payable under this Section 2.16(e) accruing
prior to one hundred eighty (180) days before such lender or the Administrative
Agent requests compensation.

      Section 2.17 CHANGE OF LENDING OFFICE. Each Lender agrees that it will use
reasonable efforts to designate an alternate Lending Office with respect to any
of its Eurodollar Loans affected by the 


                                       31
<PAGE>
matters or circumstances described in Sections 2.14, 2.15 or 2.16 to reduce the
liability of the Company or avoid the results provided thereunder, so long as
such designation is not disadvantageous to such Lender as determined by such
Lender in its sole discretion; provided that such Lender shall have no
obligation to so designate an alternate Lending Office located in the United
States.

      Section 2.18 FUNDING LOSSES. The Company shall compensate each Lender,
upon its written request (which request shall set forth the basis for requesting
such amounts and shall, absent manifest error, be final, conclusive and binding
upon all of the parties hereto), for all losses, expenses and liabilities
(including, but not limited to, any interest paid by such Lender to lenders of
funds borrowed by it to make or carry its Eurodollar Loans to the extent not
recovered by the Lender in connection with the re-employment of such funds,
which the Lender may sustain: (a) if for any reason (other than a default by
such Lender) a Borrowing of Eurodollar Loans does not occur on the date
specified therefor in a Borrowing Request (whether or not withdrawn), including,
but not limited to a failure by the Company to fulfill on the date of any
Borrowing of Eurodollar Loans the conditions set forth in Article 3, or to
convert or continue any Eurodollar Loan hereunder after irrevocable notice of
such conversion or continuation has been given pursuant to Section 2.11; (b) if
any payment, prepayment or conversion of any of its Eurodollar Loans required or
permitted by any other provision of this Agreement or otherwise, or any
assignment of a Eurodollar Loan pursuant to Section 2.22, in each case is made
or deemed made on a date which is not the last day of the Interest Period
applicable thereto; or (c) if, for any reason, the Company defaults in its
obligation to repay its Eurodollar Loans or interest accrued thereon as and when
due and payable (at the due date thereof, whether at scheduled maturity, by
acceleration, irrevocable notice of prepayment or otherwise).

      Section 2.19 SHARING OF PAYMENTS, ETC. If any Lender shall obtain any
payment or reduction (including, but not limited to, any amounts received as
adequate protection of a deposit treated as cash collateral under the Bankruptcy
Code) of any obligation of the Company hereunder (whether voluntary,
involuntary, through the exercise of any right of set-off, or otherwise) in
excess of its ratable share of payments or reductions on account of such
obligations obtained by all the Lenders, such Lender shall forthwith (a) notify
each of the other Lenders and the Administrative Agent of such receipt, and (b)
purchase from the other Lenders such participations in the affected obligations
as shall be necessary to cause such purchasing Lender to share the excess
payment or reduction, net of costs incurred in connection therewith, ratably
with each of them, provided that if all or any portion of such excess payment or
reduction is thereafter recovered from such purchasing Lender or additional
costs are incurred, the purchase shall be rescinded and the purchase price
restored to the extent of such recovery or such additional costs, but without
interest. The Company agrees that any Lender so purchasing a participation from
another Lender pursuant to this Section may, to the fullest extent permitted by
law, exercise all its rights of payment (including the right of set-off) with
respect to such participation as fully as if such Lender were the direct
creditor of the Company in the amount of such participation.

      Section    2.20   TAXES.

            (a) PAYMENTS FREE AND CLEAR. Any and all payments by or on account
of any obligation of the Company hereunder shall be made free and clear of and
without deduction for any Indemnified Taxes or Other Taxes; PROVIDED that if the
Company shall be required to deduct any Indemnified Taxes or Other Taxes from
such payments, then (1) the sum payable shall be increased as necessary so that
after making all required deductions (including deductions applicable to
additional sums payable under this Section) the Administrative Agent, Lender or
Issuing Bank (as the case may be) receives an amount equal to the sum it would
have received had no such deductions been made, (2) the Company shall make such
deductions, and (3) the Company shall pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable law.

                                       32
<PAGE>
            (b) OTHER TAXES. In addition, the Company shall pay any Other Taxes
to the relevant Governmental Authority in accordance with applicable law.

            (c) INDEMNIFICATION. The Company shall indemnify the Administrative
Agent, each Lender and the Issuing Bank, upon written demand therefor, for the
full amount of any Indemnified Taxes or Other Taxes paid by the Administrative
Agent, such Lender or the Issuing Bank, as the case may be, on or with respect
to any payment by or on account of any obligation of the Company hereunder
(including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) and any penalties, interest
and reasonable expenses arising therefrom or with respect thereto, whether or
not such Indemnified Taxes or Other Taxes were correctly or legally imposed or
asserted by the relevant Governmental Authority. A certificate as to the amount
of such payment or liability delivered to the Company by a Lender or the Issuing
Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender
or the Issuing Bank, shall be conclusive absent manifest error.

            (d) RECEIPTS. As soon as practicable after any payment of
Indemnified Taxes or Other Taxes by the Company to a Governmental Authority, the
Company shall deliver to the Administrative Agent the original or a certified
copy of a receipt issued by such Governmental Authority evidencing such payment,
a copy of the return reporting such payment or other evidence of such payment
reasonably satisfactory to the Administrative Agent.

            (e) SURVIVAL. Without prejudice to the survival of any other
agreement contained herein, the agreements and obligations contained in this
Section 2.20 shall survive the payment in full of principal and interest
hereunder.

            (f) LENDER REPRESENTATIONS AND AGREEMENTS. Any Foreign Lender that
is entitled to an exemption from or reduction of withholding tax under the law
of the jurisdiction in which the Company is located, or any treaty to which such
jurisdiction is a party, with respect to payments under this Agreement shall
deliver to the Company (with a copy to the Administrative Agent), at the time or
times prescribed by applicable law, such properly completed and executed
documentation prescribed by applicable law or reasonably requested by the
Company as will permit such payments to be made without withholding or at a
reduced rate.

      Section 2.21 PRO RATA TREATMENT. Subject to Section 2.4(b), each Borrowing
of Revolving Credit Loans shall be made, each payment on account of any
commitment fee in respect of the Revolving Credit Commitments hereunder shall be
allocated by the Administrative Agent, and any reduction of the Revolving Credit
Commitments of the Lenders shall be allocated by the Administrative Agent, PRO
RATA according to the relevant Revolving Credit Percentages of the Lenders.
Subject to Section 2.4(b), each payment (including each prepayment) on account
of principal of and interest on any Revolving Credit Loans shall be allocated by
the Administrative Agent PRO RATA according to the respective outstanding
principal amounts of such Revolving Credit Loans then held by the Lenders. Each
payment on account of principal of and interest on any Term Loans shall be
allocated by the Administrative Agent PRO RATA according to the respective
outstanding principal amounts of such Term Loans then held by the Lenders. All
proceeds (including proceeds from the realization upon the Collateral) received
after acceleration of the maturity of the Loans, shall be applied FIRST to
reimbursement of expenses and indemnities provided for in this Agreement and the
Financing Documents; SECOND, to other Lender Indebtedness (including, without
limitation, Letter of Credit Liabilities) until repaid in full PRO RATA to each
Lender; and, THIRD, to any other Person entitled to receive such proceeds in
accordance with applicable law.

      Section 2.22 REPLACEMENT OF LENDERS. If any Lender does not make a
Eurodollar Loan pursuant to Section 2.15, is subject to increased costs pursuant
to Section 2.16, fails to designate an alternate 

                                       33
<PAGE>
Lending Office pursuant to Section 2.17, or is owed or reasonably anticipates
being owed additional amounts pursuant to Section 2.20, the Company shall have
the right, if no Default then exists, to replace such Lender with another bank
or financial institution with the consent of the Administrative Agent, which
consent shall not be unreasonably withheld, provided that (a) the obligations of
the Company owing to the Lender being replaced (including such increased costs)
that are not being assigned to the replacement lender shall be paid in full to
the Lender being replaced concurrently with such replacement lender, (b) the
replacement lender shall execute an Assignment and Acceptance pursuant to which
it shall become a party hereto as provided in Section 9.7, and (c) upon

payment of amounts referred to in clause (a), the replacement lender shall
constitute a "Lender" hereunder and the Lender being so replaced shall no longer
constitute a "Lender" hereunder.

                           THE ADMINISTRATIVE AGENT

      Section 8.1 APPOINTMENT OF ADMINISTRATIVE AGENT. Each Lender (and each
Affiliate by and through its affiliated Lender) and the Issuing Bank hereby
designates Chase Bank of Texas, N.A., as Administrative Agent to act as herein
specified and as specified in the other Financing Documents. Each Lender (and
each Affiliate by and through its affiliated Lender) and the Issuing Bank hereby
irrevocably authorizes the Administrative Agent to take such action on its
behalf under the provisions of this Agreement, the Notes, and the other
Financing Documents and to exercise such powers and to perform such duties
hereunder and thereunder as are specifically delegated to or required of the
Administrative Agent by the terms hereof and thereof and such other powers as
are reasonably incidental thereto. The Administrative Agent may perform any of
its duties hereunder by or through its agents or employees.

      Section 8.2 LIMITATION OF DUTIES OF ADMINISTRATIVE AGENT. The
Administrative Agent shall have no duties or responsibilities except those
expressly set forth with respect to the Administrative Agent in this Agreement
and as specified in the other Financing Documents. Neither the Administrative
Agent nor any of its officers, directors, employees or agents shall be liable
for any action taken or omitted by it as such hereunder or in connection
herewith, unless caused by its or their gross negligence or willful misconduct.
The duties of the Administrative Agent shall be mechanical and administrative in
nature; the Administrative Agent shall not have by reason of this Agreement a
fiduciary relationship in respect of any Lender; and nothing in this Agreement,
expressed or implied, is intended to or shall be so construed as to impose upon
the Administrative Agent any obligations in respect of this Agreement except as
expressly set forth herein.

      Section    8.3    LACK OF RELIANCE ON THE ADMINISTRATIVE AGENT.

            (a) INDEPENDENT INVESTIGATION. Independently and without reliance
upon the Administrative Agent, each Lender, to the extent it deems appropriate,
has made and shall continue to make (1) its own independent investigation of the
financial condition and affairs of the Company in connection with the taking or
not taking of any action in connection herewith, and (2) its own appraisal of
the creditworthiness 

                                       55
<PAGE>
of the Company, and, except as expressly provided in this Agreement, and the
other Financing Documents, the Administrative Agent shall have no duty or
responsibility, either initially or on a continuing basis, to provide any Lender
with any credit or other information with respect thereto, whether coming into
its possession before the consummation of the transactions contemplated herein
or at any time or times thereafter.

            (b) ADMINISTRATIVE AGENT NOT RESPONSIBLE. The Administrative Agent
shall not be responsible to any Lender or the Issuing Bank for any recitals,
statements, information, representations or warranties herein or in any
document, certificate or other writing delivered in connection herewith or for
the execution, effectiveness, genuineness, validity, enforceability,
collectibility, priority or sufficiency of this Agreement, the Notes, the
Letters of Credit or the other Financing Documents or the financial condition of
the Company or be required to make any inquiry concerning either the performance
or observance of any of the terms, provisions or conditions of this Agreement,
the Notes or the other Financing Documents, or the financial condition of the
Company, or the existence or possible existence of any Default or Event of
Default.

      Section 8.4 CERTAIN RIGHTS OF THE ADMINISTRATIVE AGENT. If the
Administrative Agent shall request instructions from the Required Lenders with
respect to any act or action (including the failure to act) in connection with
this Agreement, the Notes and the other Financing Documents, the Administrative
Agent shall be entitled to refrain from such act or taking such action unless
and until the Administrative Agent shall have received instructions from the
Required Lenders; and the Administrative Agent shall not incur liability to any
Person by reason of so refraining. Without limiting the foregoing, no Lender
shall have any right of action whatsoever against the Administrative Agent as a
result of the Administrative Agent acting or refraining from acting under this
Agreement, the Notes and the other Financing Documents in accordance with the
instructions of the Required Lenders, or to the extent required by Section 9.2,
all of the Lenders.

      Section 8.5 RELIANCE BY ADMINISTRATIVE AGENT. The Administrative Agent
shall be entitled to rely, and shall be fully protected in relying, upon any
note, writing, resolution, notice, statement, certificate, telex, teletype or
telecopier message, cablegram, radiogram, order or other documentary
teletransmission or telephone message believed by it to be genuine and correct
and to have been signed, sent or made by the proper Person. The Administrative
Agent may consult with legal counsel (including counsel for the Company),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken by it in good faith in
accordance with the advice of such counsel, accountants or experts.

      Section 8.6 INDEMNIFICATION OF ADMINISTRATIVE AGENT. TO THE EXTENT THE
ADMINISTRATIVE AGENT IS NOT REIMBURSED AND INDEMNIFIED BY THE COMPANY, EACH
LENDER WILL REIMBURSE AND INDEMNIFY THE ADMINISTRATIVE AGENT ON A PRO RATA
BASIS, FOR AND AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES,
PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES (INCLUDING REASONABLE
COUNSEL FEES AND DISBURSEMENTS) OR DISBURSEMENTS OF ANY KIND OR NATURE
WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE
ADMINISTRATIVE AGENT IN PERFORMING ITS DUTIES HEREUNDER, IN ANY WAY RELATING TO
OR ARISING OUT OF THIS AGREEMENT AND BY REASON OF THE ORDINARY NEGLIGENCE OF THE
ADMINISTRATIVE AGENT; PROVIDED THAT NO LENDER SHALL BE LIABLE TO THE
ADMINISTRATIVE AGENT FOR ANY PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES,
DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS
RESULTING FROM, AS TO THE ADMINISTRATIVE AGENT, THE ADMINISTRATIVE AGENT'S GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT.

      Section 8.7 THE ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY. With
respect to their obligations under this Agreement, the Loans made by it and the
Notes issued to it, the Administrative Agent 

                                       56
<PAGE>
shall have the same rights and powers hereunder as any other Lender or holder of
a Note and may exercise the same as though it were not performing the duties, if
any, specified herein; and the terms "Lenders," "Required Lenders," "holders of
Notes" or any similar terms shall, unless the context clearly otherwise
indicates, include the Administrative Agent in its individual capacity. The
Administrative Agent may accept deposits from, lend money to, and generally
engage in any kind of banking, trust, financial advisory or other business with
the Company or any affiliate of the Company as if it were not performing the
duties, if any, specified herein, and may accept fees and other consideration
from the Company for services in connection with this Agreement and otherwise
without having to account for the same to the Lenders.

      Section 8.8 MAY TREAT LENDER AS OWNER. The Company, the Administrative
Agent and the Issuing Bank may deem and treat each Lender as the owner of such
Lender's Note for all purposes hereof unless and until a written notice of the
assignment or transfer thereof shall have been filed with the Administrative
Agent. Any request, authority or consent of any Person who at the time of making
such request or giving such authority or consent is the owner of a Note shall be
conclusive and binding on any subsequent owner, transferee or assignee of such
Note or any promissory note or notes issued in exchange therefor.

      Section    8.9    SUCCESSOR ADMINISTRATIVE AGENT.

            (a) ADMINISTRATIVE AGENT RESIGNATION. The Administrative Agent may
resign at any time by giving written notice thereof to the Lenders, the Issuing
Bank and the Company and may be removed at any time with or without cause by the
Required Lenders. Upon any such resignation or removal, the Required Lenders
shall have the right, upon five days' notice to the Company, to appoint a
successor Administrative Agent, subject to the approval of the Company, such
approval not to be unreasonably withheld. If no successor Administrative Agent
shall have been so appointed by the Required Lenders, and shall have accepted
such appointment, within 30 days after the retiring Administrative Agent's
giving of notice of resignation or the Required Lenders' removal of the retiring
Administrative Agent, then, upon five days' notice to the Company, the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent (subject to approval of the Company, such approval not to
be unreasonably withheld), which shall be a bank which maintains an office in
the United States, or a commercial bank organized under the laws of the United
States of America or of any State thereof, or any Affiliate of such bank, having
a combined capital and surplus of at least $250,000,000.

            (b) RIGHTS, POWERS, ETC. Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations under this Agreement. After any retiring Administrative Agent's
resignation or removal hereunder as Administrative Agent, the provisions of this
Article 8 shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Administrative Agent under this Agreement.

Section. The Required Lenders may, or, with the written consent of the Required
Lenders, the Administrative Agent shall, from time to time, (x) enter into with
the Company, written amendments, supplements or modifications hereto and to the
other Financing Documents for the purpose of adding any provisions to this
Agreement or to the other Financing Documents or changing in any manner the
rights or obligations of the Lenders or the Company hereunder or thereunder or
(y) waive at the Company's request, on such terms and conditions as the Required
Lenders or the Administrative Agent, as the case may be, may specify in such
instrument, any of the requirements of this Agreement or the other Financing
Documents or any Default and its consequences; PROVIDED, HOWEVER, that no such
waiver and no such amendment, supplement or modification shall:

            (a) reduce the amount or extend the scheduled date of maturity of
any Loan or any Reimbursement Obligation or of any scheduled installment thereof
or reduce the stated rate of any interest or fee payable hereunder or extend the
scheduled date of any payment thereof or modify any provision that provides for

Indebtedness to provide for a non-ratable sharing thereof or increase the amount
or extend the expiration date of any Lender's Revolving Credit Commitment or
Term Loan Commitment or amend, modify or waive any provision of Section 2.19, in
each case without the prior written consent of each Lender directly affected
thereby;

            (b) change the currency in which any Loan or Reimbursement
Obligation is payable or amend, modify or waive any provision of this Section

            (e) amend, modify or waive (1) any Letter of Credit Liability
without the written consent of the Issuing Bank or (2) any Letter of Credit
without the consent of each Lender if such Letter of Credit, after giving effect
to such amendment, modification or waiver, would no longer satisfy the
requirements hereof if such Letter of Credit was being issued AB INITIO at such
time, PROVIDED THAT in all cases other than clauses (1) or (2), only the consent
of the Issuing Bank shall be required to amend, modify or waive any Letter of
Credit.

            Any waiver and any amendment, supplement or modification pursuant to
this Section 9.2 shall apply to each of the Lenders and shall be binding upon
the Company, the Lenders, the Administrative Agent and all future holders of the
Loans. In the case of any waiver, the Company, the Lenders and the
Administrative Agent shall be restored to their former position and rights
hereunder and under the other Financing Documents, and any Default waived shall
be deemed to be cured and not continuing; but no such waiver shall extend to any
subsequent or other Default, or impair any right consequent thereon.

      Section 9.3 NO WAIVER; REMEDIES CUMULATIVE. No failure or delay on the
part of the Company or the Administrative Agent or any Lender or any holder of

                                       58
<PAGE>
remedy under this Agreement or any other Financing Document and no course of
dealing between the Company and the Administrative Agent or any Lender or any
holder of any Note shall operate as a waiver thereof, nor shall any single or
partial exercise of any right or remedy under the Notes, this Agreement or any
other Financing Document preclude any other or further exercise thereof or the
exercise of any other right or remedy under the Notes, this Agreement or any
other Financing Document. The rights and remedies herein expressly provided are
cumulative and not exclusive of any rights or remedies which the Company, the
Administrative Agent or any Lender would otherwise have. No notice to or demand
on the Company not required under the Notes, this Agreement or any other
Financing Document in any case shall entitle the Company to any other or further
notice or demand in similar or other circumstances or constitute a waiver of the
rights of the Administrative Agent or the Lenders to any other or further action
in any circumstances without notice or demand.

      Section 9.4 PAYMENT OF EXPENSES, INDEMNITIES, ETC. The Company agrees to

rights of offset that any Lender or the Issuing Bank may have under applicable
law, each Lender or other holder of a Note, or any other Lender Indebtedness
shall, upon the occurrence of any Event of Default and at any time during the
continuance thereof and whether or not such Lender, the Issuing Bank or such
holder has made any demand or the Company's obligations are matured, have the
right at any time and from time to time, without notice to the Company (any such
notice being expressly waived by the Company) to set-off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by any Lender or the Issuing Bank
to or for the credit or the account of the Company against any and all of the
Lender Indebtedness owing to such Lender or the Issuing Bank then outstanding,
subject to the provisions of Section 2.19.

      Section 9.6 BENEFIT OF AGREEMENT. The Notes, this Agreement and the other
Financing Documents shall be binding upon and inure to the benefit of and be
enforceable by the respective successors and assigns of the parties hereto,
provided that the Company may not assign or transfer any of its interest
hereunder or thereunder without the prior written consent of the Lenders.

      Section    9.7    SUCCESSORS AND ASSIGNS; PARTICIPATIONS AND ASSIGNMENTS.

            (a) The provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and assigns
permitted hereby (including any Affiliate of the Issuing Bank that issues any
Letter of Credit), except that the Company may not assign or otherwise transfer
any of its rights or obligations hereunder without the prior written consent of
each Lender (and any attempted assignment or transfer by the Company without
such consent shall be null and void). Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby (including any
Affiliate of the Issuing Bank that issues any Letter of Credit) and, to the
extent expressly contemplated hereby, the Related Parties of each of the
Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

            (b) Any Lender may assign to one or more assignees all or a portion
of its rights and obligations under this Agreement (including all or a portion
of its Commitment and the Loans at the time owing to it); PROVIDED that (i)
except in the case of an assignment to a Lender or an Affiliate of a Lender,
each of the Company and the Administrative Agent (and, in the case of an
assignment of all or a portion of a Commitment or any Lender's obligations in
respect of its Revolving Credit Exposure, the Issuing Bank) must give their
prior written consent to such assignment (which consent shall not be
unreasonably withheld), (ii) except in the case of an assignment to a Lender or
an Affiliate of a Lender or an assignment of the entire remaining amount of the
assigning Lender's Commitment, the amount of the Commitment of the assigning
Lender subject to each such assignment (determined as of the date the Assignment
and Acceptance with respect to such assignment is delivered to the
Administrative Agent) shall not be less than $5,000,000 unless each of the
Company and the Administrative Agent otherwise consent, (iii) each partial
assignment shall be made as an assignment of a proportionate part of all the
assigning Lender's rights and obligations under this Agreement, (iv) the parties
to each assignment shall execute and deliver to the Administrative Agent an
Assignment and Acceptance, together with a processing and recordation fee of
$3,500, and (v) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire; and PROVIDED FURTHER that
any consent of the Company otherwise required under this paragraph shall not be

                                       61
<PAGE>
required if an Event of Default has occurred and is continuing. Subject to
acceptance and recording thereof pursuant to Section 9.7(d), from and after the
effective date specified in each Assignment and Acceptance the assignee
thereunder shall be a party hereto and, to the extent of the interest assigned
by such Assignment and Accep tance, have the rights and obligations of a Lender
under this Agreement, and the assigning Lender thereunder shall, to the extent
of the interest assigned by such Assignment and Acceptance, be released from its
obliga tions under this Agreement (and, in the case of an Assignment and
Acceptance covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of Sections 2.16, 2.18, 2.20 and 9.4). Any
assignment or transfer by a Lender of rights or obligations under this Agreement
that does not comply with this paragraph shall be treated for purposes of this
Agreement as a sale by such Lender of a participation in such rights and
obligations in accordance with this Section 9.7(b).

            (c) The Administrative Agent, acting for this purpose as an agent of
the Company, shall maintain at one of its offices in Houston, Texas a copy of
each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitment of,
and principal amount of the Loans and Reimbursement Obligations owing to, each
Lender pursuant to the terms hereof from time to time (the "REGISTER"). The
entries in the Register shall be conclusive, and the Company, the Administrative
Agent, the Issuing Bank and the Lenders may treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for
all purposes of this Agreement, notwithstanding notice to the contrary. The
Register shall be available for inspection by the Company, the Issuing Bank and
any Lender, at any reasonable time and from time to time upon reasonable prior
notice.

            (d) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, the assignee's completed
Administrative Questionnaire (unless the assignee shall already be a Lender
hereunder), the processing and recordation fee referred to in Section 9.7(b) and
any written consent to such assignment required by Section 9.7(b), the
Administrative Agent shall accept such Assignment and Acceptance and record the
information contained therein in the Register. No assignment shall be effective
for purposes of this Agreement unless it has been recorded in the Register as
provided in this paragraph.

            (e) Any Lender may, without the consent of the Company, the
Administrative Agent or the Issuing Bank, sell participations to one or more
banks or other entities (a "PARTICIPANT") in all or a portion of such Lender's
rights and obligations under this Agreement (including all or a portion of its
Commitment and the Loans and Reimbursement Obligations owing to it); PROVIDED
that (i) such Lender's obligations under this Agreement shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for
the performance of such obligations and (iii) the Company, the Administrative
Agent, the Issuing Bank and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement; PROVIDED that such
agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, modification or waiver
described in Sections 9.2(a) or 9.2(b) that affects such Participant. Subject to
this Section 9.7(e), the Company agrees that each Participant shall be entitled
to the benefits of Sections 2.16, 2.18 and 2.20 to the same extent as if it were
a Lender and had acquired its interest by assignment pursuant to Section 9.7(b).
To the extent permitted by law, each Participant also shall be entitled to the
benefits of Section 9.5 as though it were a Lender, provided such Participant
agrees to be subject to Section 2.19 as though it were a Lender.

            (f) A Participant shall not be entitled to receive any greater
payment under Section 2.18 or 2.20 than the applicable Lender would have been
entitled to receive with respect to the participation sold 

                                       62
<PAGE>
to such Participant, unless the sale of the participation to such Participant is
made with the Company's prior written consent. A Participant that would be a
Foreign Lender if it were a Lender shall not be entitled to the benefits of
Section 2.20 unless the Company is notified of the participation sold to such
Participant and such Participant agrees, for the benefit of the Company, to
comply with Section 2.20(f) as though it were a Lender.

            (g) Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement to secure obligations
of such Lender, including any pledge or assignment to secure obligations to a
Federal Reserve Bank, and this Section 9.7 shall not apply to any such pledge or
assignment of a security interest; PROVIDED that no such pledge or assignment of
a security interest shall release a Lender from any of its obligations hereunder
or substitute any such pledgee or assignee for such Lender as a party hereto.

            (h) The Company authorizes each Lender to disclose to any
participant or Assignee (each, a "TRANSFEREE") and any prospective Transferee
any and all information in such Lender's possession concerning the Company and
its Affiliates which has been delivered to such Lender by or on behalf of the
Company pursuant to this Agreement or which has been delivered to such Lender by
or on behalf of the Company in connection with such Lender's credit evaluation
of the Company and its Affiliates prior to becoming a party to this Agreement.
No assignment or participation made or purported to be made to any Transferee
shall be effective without the prior written consent of the Company if it would
require it to make any filing with any Governmental Authority or qualify any
Loan or Note under the laws of any jurisdiction, and the Company shall be
entitled to request and receive such information and assurances as it may
reasonably request from any Lender or any Transferee to determine whether any
such filing or qualification is required or whether any assignment or
participation is otherwise in accordance with applicable law.

      Section    9.8    GOVERNING LAW; SUBMISSION TO JURISDICTION; ETC.

            (A) GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
THE PARTIES HEREUNDER AND UNDER THE NOTES SHALL BE CONSTRUED IN ACCORDANCE WITH
AND BE GOVERNED BY THE LAWS OF THE STATE OF TEXAS AND, TO THE EXTENT
CONTROLLING, LAWS OF THE UNITED STATES OF AMERICA.

            (B) SUBMISSION TO JURISDICTION. ANY LEGAL ACTION OR PROCEEDING WITH
RESPECT TO THIS AGREEMENT, THE NOTES OR THE OTHER FINANCING DOCUMENTS MAY BE
BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF THE UNITED STATES OF AMERICA
FOR THE SOUTHERN DISTRICT OF TEXAS, AND, BY EXECUTION AND DELIVERY OF THIS
AGREEMENT, THE COMPANY, LENDER AND AGENT HEREBY ACCEPTS FOR ITSELF AND IN
RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE
AFORESAID COURTS. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY OBJECTION,
INCLUDING, BUT NOT LIMITED TO, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON
THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS.

            (C) WAIVER OF CONSEQUENTIAL DAMAGES. TO THE MAXIMUM EXTENT ALLOWED
BY APPLICABLE LAW, EACH OF THE COMPANY, THE ADMINISTRATIVE AGENT, THE ISSUING
BANK AND THE LENDERS (I) IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO CLAIM OR
RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL
DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (II)
CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR COUNSEL FOR ANY PARTY
HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; AND (IV)
ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS 

                                       63
<PAGE>
AGREEMENT, THE OTHER FINANCING DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED
HEREBY AND THEREBY BASED UPON, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS CONTAINED IN THIS SECTION.

      Section 9.9 INDEPENDENT NATURE OF LENDERS' RIGHTS. The amounts payable at
any time hereunder to each Lender shall be a separate and independent debt, and
each Lender shall be entitled to protect and enforce its rights arising out of
this Agreement, and it shall not be necessary for any other Lender to be joined
as an additional party in any proceeding for such purpose.

      Section 9.10 INVALIDITY. In the event that any one or more of the
provisions contained in the Notes, this Agreement or in any other Financing
Document shall, for any reason, be held invalid, illegal or unenforceable in any
respect, (a) the Company agrees that such invalidity, illegality or
unenforceability shall not affect any other provision of the Notes, this
Agreement or any other Financing Document and (b) the Company and the
Administrative Agent (acting on behalf and at the direction of the Lenders) will
negotiate in good faith to amend such provision so as to be legal, valid, and
enforceable.

      Section 9.11 RENEWAL, EXTENSION OR REARRANGEMENT. All provisions of this
Agreement and of any other Financing Documents relating to the Notes or other
Lender Indebtedness shall apply with equal force and effect to each and all
promissory notes hereafter executed which in whole or in part represent a
renewal, extension for any period, increase or rearrangement of any part of the
Lender Indebtedness originally represented by the Notes, or of any part of such
other Lender Indebtedness.

      Section 9.12 CONFIDENTIALITY. Each of the Administrative Agent, the
Issuing Bank and the Lenders agrees to maintain the confidentiality of the
Information (as defined below), except that Information may be disclosed (a) to
its and its Affiliates' directors, officers, employees and agents, including
accountants, legal counsel and other advisors (it being understood that the
Persons to whom such disclosure is made will be informed of the confidential
nature of such Information and instructed to keep such Information
confidential), (b) to the extent requested by any regulatory authority, (c) to
the extent required by applicable laws or regulations or by any subpoena or
similar legal process, (d) to any other party to this Agreement, (e) in
connection with the exercise of any remedies hereunder or any suit, action or
proceeding relating to this Agreement or the enforcement of rights hereunder,
(f) subject to an agreement containing provisions substantially the same as
those of this Section, to any assignee of or Participant in, or any prospective
assignee of or Participant in, any of its rights or obligations under this
Agreement, (g) with the consent of the Company or (h) to the extent such
Information (i) becomes publicly available other than as a result of a breach of
this Section or (ii) becomes available to the Administrative Agent, the Issuing
Bank or any Lender on a nonconfidential basis from a source other than the
Company. For the purposes of this Section, "INFORMATION" means all information
received from the Company relating to the Company or its business, other than
any such information that is available to the Administrative Agent, the Issuing
Bank or any Lender on a nonconfidential basis prior to disclosure by the
Company; PROVIDED that, in the case of information received from the Company
after the date hereof, such information is clearly identified at the time of
delivery as confidential. Any Person required to maintain the confidentiality of
Information as provided in this Section shall be considered to have complied
with its obligation to do so if such Person has exercised the same degree of
care to maintain the confidentiality of such Information as such Person would
accord to its own confidential information.

      Section 9.13 INTEREST. It is the intention of the parties hereto to
conform strictly to usury laws applicable to the Administrative Agent, the
Issuing Bank and the Lenders (collectively, the "FINANCING PARTIES") and the
Transactions. Accordingly, if the Transactions would be usurious as to any
Financing Party under laws applicable to it, then, notwithstanding anything to
the contrary in the Notes, this Agreement or in any other Financing Document or
agreement entered into in connection with the Transactions or as security

                                       64
<PAGE>
for the Notes, it is agreed as follows: (a) the aggregate of all consideration
which constitutes interest under law applicable to any Financing Party that is
contracted for, taken, reserved, charged or received by such Financing Party
under the Notes, this Agreement or under any of such other Financing Documents
or agreements or otherwise in connection with the Transactions shall under no
circumstances exceed the maximum amount allowed by such applicable law, (b) in
the event that the maturity of the Notes is accelerated for any reason, or in
the event of any required or permitted prepayment, then such consideration that
constitutes interest under law applicable to any Financing Party may never
include more than the maximum amount allowed by such applicable law, and (c)
excess interest, if any, provided for in this Agreement or otherwise in
connection with the Transactions shall be canceled automatically by such
Financing Party and, if theretofore paid, shall be credited by such Financing
Party on the principal amount of the Company's Indebtedness to such Financing
Party (or, to the extent that the principal amount of the Company's Indebtedness
to such Financing Party shall have been or would thereby be paid in full,
refunded by such Financing Party to the Company). The right to accelerate the
maturity of the Notes does not include the right to accelerate any interest
which has not otherwise accrued on the date of such acceleration, and the
Financing Parties do not intend to collect any unearned interest in the event of
acceleration. All sums paid or agreed to be paid to the Financing Parties for
the use, forbearance or detention of sums included in the Lender Indebtedness
shall, to the extent permitted by law applicable to such Financing Party, be
amortized, prorated, allocated and spread throughout the full term of the Notes
until payment in full so that the rate or amount of interest on account of the
Lender Indebtedness does not exceed the applicable usury ceiling, if any. As
used in this Section, the terms "APPLICABLE LAW" or "LAWS APPLICABLE TO ANY
FINANCING PARTY" shall mean the law of any jurisdiction whose laws may be
mandatorily applicable notwithstanding other provisions of this Agreement, or
law of the United States of America applicable to any Financing Party and the
Transactions which would permit such Financing Party to contract for, charge,
take, reserve or receive a greater amount of interest than under such
jurisdiction's law. To the extent that Section 346 of the Texas Finance Code is
relevant to any Financing Party for the purpose of determining the Highest
Lawful Rate, such Financing Party hereby elects to determine the applicable rate
ceiling under such Article by the indicated (weekly) rate ceiling from time to
time in effect, subject to such Financing Party's right subsequently to change
such method in accordance with applicable law.

      Section 9.14 EXISTING CREDIT AGREEMENT. This Agreement amends and restates
in its entirety the Existing Credit Agreement, and the "Commitments" (as defined
in the Existing Credit Agreement) of the lenders party to the Existing Credit
Agreement are hereby terminated.

      Section 9.15 ENTIRE AGREEMENT. THE NOTES, THIS AGREEMENT AND THE OTHER
FINANCING DOCUMENTS EMBODY THE ENTIRE AGREEMENT AND UNDERSTANDING BETWEEN THE
ADMINISTRATIVE AGENT, THE ISSUING BANK OR THE LENDERS AND THE OTHER RESPECTIVE
PARTIES HERETO AND THERETO AND SUPERSEDE ALL PRIOR AGREEMENTS AND UNDERSTANDINGS
BETWEEN SUCH PARTIES RELATING TO THE SUBJECT MATTER HEREOF AND THEREOF AND MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS AGREEMENTS OF THE
PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

      Section 9.16 ATTACHMENTS. The exhibits, schedules and annexes attached to
this Agreement are incorporated herein and shall be considered a part of this
Agreement for the purposes stated herein, except that in the event of any
conflict between any of the provisions of such exhibits and the provisions of
this Agreement, the provisions of this Agreement shall prevail.

      Section 9.17 COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original but all of which
shall together constitute one and the same instrument.

      Section 9.18 SURVIVAL OF INDEMNITIES. The Company's obligations under
Sections 2.16, 2.18, 2.20 and 9.4 shall survive the payment in full of the Loans
and the Letter of Credit Liabilities.

      Section 9.19 HEADINGS DESCRIPTIVE. The headings of the several sections
and subsections of this Agreement, and the Table of Contents are inserted for
convenience only and shall not in any way affect the meaning or construction of
any provision of this Agreement.

      Section 9.20 SATISFACTION REQUIREMENT. If any agreement, certificate,
instrument or other writing, or any action taken or to be taken, is by the terms
of this Agreement required to be satisfactory to any party, the determination of
such satisfaction shall be made by such party in its sole and exclusive judgment
exercised reasonably and in good faith.

      Section 9.21 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO
SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER
FINANCING DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF
THE TERMS OF THIS AGREEMENT AND THE OTHER FINANCING DOCUMENTS; THAT IT HAS IN
FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE
OF THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN
REPRESENTED BY LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING
ITS EXECUTION OF THIS AGREEMENT AND THE OTHER FINANCING DOCUMENTS; AND HAS
RECEIVED THE ADVICE OF ITS ATTORNEYS IN ENTERING INTO THIS AGREEMENT AND THE
OTHER FINANCING DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF
THIS AGREEMENT AND THE OTHER FINANCING DOCUMENTS RESULT IN ONE PARTY ASSUMING
THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE
OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES
AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY
EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER FINANCING DOCUMENTS ON THE
BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE
PROVISION IS NOT "CONSPICUOUS."

all terms beginning with a capital letter which are defined in the Credit
Agreement shall have the same meanings herein as therein.

                                   ARTICLE 2

                                 THE GUARANTY

      Section 2.1 LIABILITIES GUARANTEED. Guarantor hereby irrevocably and
unconditionally guarantees the prompt payment of the Liabilities when due,
whether at maturity or otherwise, provided, however, that, notwithstanding
anything herein or in any other Financing Document to the contrary, the maximum
liability of Guarantor hereunder shall in no event exceed the Maximum Guaranteed
Amount.

      Section 2.2 NATURE OF GUARANTY. This Guaranty Agreement is an absolute,
irrevocable, completed and continuing guaranty of payment and not a guaranty of
collection, and no notice of the Liabilities or any extension of credit already
or hereafter contracted by or extended to Company need be given to Guarantor.
This Guaranty Agreement may not be revoked by Guarantor and shall continue to be
effective with respect to debt under the Liabilities arising or created after
any attempted revocation by Guarantor and shall remain in full force and effect
until the Liabilities are paid in full and the Commitments are terminated,
notwithstanding that from time to time prior thereto no Liabilities may be
outstanding. The Company and the Lenders may modify, alter, rearrange, extend
for any period and/or renew from time to time, the Liabilities, and the Lenders
may waive any Default or Events of Default without notice to the Guarantor and
in such event Guarantor will remain fully bound hereunder on the Liabilities.
This Guaranty Agreement shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of the Liabilities is rescinded or must
otherwise be returned by any of the Lenders upon the insolvency, bankruptcy or
reorganization of the Company or otherwise, all as though such payment had not
been made. This Guaranty Agreement may be enforced by the Agent and any
subsequent holder of any of the Liabilities and shall not be discharged by the
assignment or negotiation of all or part of the Liabilities. Except as
specifically required in this Guaranty, Guarantor hereby expressly waives
presentment, demand, notice of non-payment, protest and notice of protest and
dishonor, notice of Default or Event of Default, notice of intent to accelerate
the maturity and notice of acceleration of the maturity and any other notice in
connection with the Liabilities, and also notice of acceptance of this Guaranty
Agreement, acceptance on the part of the Lenders being conclusively presumed by
the Lenders' request for this Guaranty Agreement and delivery of the same to the
Agent.

      Section 2.3 AGENT'S RIGHTS. Guarantor authorizes the Agent, without notice
or demand and without affecting Guarantor's liability hereunder, to take and
hold security for the payment of this Guaranty Agreement and/or the Liabilities,
and exchange, enforce, waive and release any such security; and to apply such
security and direct the order or manner of sale thereof as the Agent in its
discretion may determine; and to obtain a guaranty of the Liabilities from any
one or more Persons and at any time or times to enforce, waive, rearrange,
modify, limit or release any of such other Persons from their obligations under
such guaranties.

      Section 2.4       GUARANTOR'S WAIVERS.

            (a) GENERAL. Guarantor waives any right to require any of the
      Lenders to (i) proceed against the Company or any other person liable on
      the Liabilities, (ii) enforce any of their rights against any other
      guarantor of the Liabilities, (iii) proceed or enforce any of their rights
      against or exhaust any security given to secure the Liabilities, (iv) have
      the Company joined with Guarantor in any suit arising out of this Guaranty
      Agreement and/or the Liabilities, or (v) pursue any other remedy in the
      Lenders' powers whatsoever. The Lenders shall not be required to mitigate
      damages 

                                      E-5
<PAGE>
      or take any action to reduce, collect or enforce the Liabilities.
      Guarantor waives any defense arising by reason of any disability, lack of
      corporate authority or power, or other defense of the Company or any other
      guarantor of the Liabilities, and shall remain liable hereon regardless of
      whether the Company or any other guarantor be found not liable thereon for
      any reason. Whether and when to exercise any of the remedies of the
      Lenders under any of the Financing Documents shall be in the sole and
      absolute discretion of the Agent, and no delay by the Agent in enforcing
      any remedy, including delay in conducting a foreclosure sale, shall be a
      defense to the Guarantor's liability under this Guaranty Agreement.

            (b) SUBROGATION. Until the Liabilities have been paid in full, the
      Guarantor waives all rights of subrogation or reimbursement against the
      Company, whether arising by contract or operation of law (including,
      without limitation, any such right arising under any federal or state
      bankruptcy or insolvency laws) and waives any right to enforce any remedy
      which the Lenders now have or may hereafter have against the Company, and
      waives any benefit or any right to participate in any security now or
      hereafter held by the Agent or any Lender.

      Section 2.5 MATURITY OF LIABILITIES; PAYMENT. Guarantor agrees that if the
maturity of any of the Liabilities is accelerated by bankruptcy or otherwise,
such maturity shall also be deemed accelerated for the purpose of this Guaranty
Agreement without demand or notice to Guarantor. Guarantor will, forthwith upon
notice from the Agent, pay to the Agent the amount due and unpaid by the Company
and guaranteed hereby. The failure of the Agent to give this notice shall not in
any way release Guarantor hereunder.

      Section 2.6 AGENT'S EXPENSES. If Guarantor fails to pay the Liabilities
after notice from the Agent of the Company's failure to pay any Liabilities at
maturity, and if the Agent obtains the services of an attorney for collection of
amounts owing by Guarantor hereunder, or obtaining advice of counsel in respect
of any of their rights under this Guaranty Agreement, or if suit is filed to
enforce this Guaranty Agreement, or if proceedings are had in any bankruptcy,
probate, receivership or other judicial proceedings for the establishment or
collection of any amount owing by Guarantor hereunder, or if any amount owing by
Guarantor hereunder is collected through such proceedings, Guarantor agrees to
pay to the Agent the Agent's reasonable attorneys' fees.

      Section 2.7 LIABILITY. It is expressly agreed that the liability of the
Guarantor for the payment of the Liabilities guaranteed hereby shall be primary
and not secondary.

      Section 2.8 EVENTS AND CIRCUMSTANCES NOT REDUCING OR DISCHARGING
GUARANTOR'S OBLIGATIONS. Guarantor hereby consents and agrees to each of the
following to the fullest extent permitted by law, and agrees that Guarantor's
obligations under this Guaranty Agreement shall not be released, diminished,
impaired, reduced or adversely affected by any of the following, and waives any
rights (including without limitation rights to notice) which Guarantor might
otherwise have as a result of or in connection with any of the following:

            (a) MODIFICATIONS, ETC. Any renewal, extension, modification,
      increase, decrease, alteration or rearrangement of all or any part of the

      Liabilities;

            (b) ADJUSTMENT, ETC. Any adjustment, indulgence, forbearance or

      dissolution, death or lack of power of the Company or Guarantor or any
      other Person at any time liable for the payment of all or part of the
      Liabilities; or any dissolution of the Company or Guarantor, or any sale,
      lease or transfer of any or all of the assets of the Company or Guarantor,
      or any changes in the shareholders, partners, or members of the Company or
      Guarantor; or any reorganization of the Company or Guarantor;

            (d) INVALIDITY OF LIABILITIES. The invalidity, illegality or

      whatsoever, including without limitation the fact that the Liabilities, or
      any part thereof, exceed the amount permitted by law, the act of creating
      the Liabilities or any part thereof is ULTRA VIRES, the officers or
      representatives executing the documents or otherwise creating the
      Liabilities acted in excess of their authority, the Liabilities violate
      applicable usury laws, the Company has valid defenses, claims or offsets
      (whether at law, in equity or by agreement) which render the Liabilities

      and performance of any document or instrument representing part of the
      Liabilities or executed in connection with the Liabilities, or given to
      secure the repayment of the Liabilities) is illegal, uncollectible,
      legally impossible or unenforceable, or the Credit Agreement or other

      directly or indirectly, jointly, severally, or jointly and severally, to
      pay, perform, guarantee or assure the payment of the Liabilities or any
      part thereof, it being recognized, acknowledged and agreed by Guarantor
      that Guarantor may be required to pay the Liabilities in full without
      assistance or support of any other Person, and Guarantor has not been
      induced to enter into this Guaranty Agreement on the basis of a
      contemplation, belief, understanding or agreement that other parties other
      than the Company will be liable to perform the Liabilities, or the Lenders
      will look to other parties to perform the Liabilities.

            (f) OTHER SECURITY. The taking or accepting of any other security,
      collateral or guaranty, or other assurance of payment, for all or any part
      of the Liabilities;

      connection with, or assuring or securing payment of, all or any part of

      Person to exercise diligence or reasonable care in the preservation,
      protection, enforcement, sale or other handling or treatment of all or any
      part of such collateral, property or security;

            (i) PAYMENTS RESCINDED. Any payment by the Company to the Lenders is
      held to constitute a preference under the bankruptcy laws, or for any
      reason the Lenders are required to refund such payment or pay such amount
      to the Company or someone else; or


                                      E-7
<PAGE>
            (j) OTHER ACTIONS TAKEN OR OMITTED. Any other action taken or
      omitted to be taken with respect to the Credit Agreement, the Liabilities,
      or the security and collateral therefor, whether or not such action or
      omission prejudices Guarantor or increases the likelihood that Guarantor
      will be required to pay the Liabilities pursuant to the terms hereof; it
      being the unambiguous and unequivocal intention of Guarantor that
      Guarantor shall be obligated to pay the Liabilities when due,
      notwithstanding any occurrence, circumstance, event, action, or omission
      whatsoever, whether contemplated or uncontemplated, and whether
      or not otherwise or particularly described herein, except for the full and
      final payment and satisfaction of the Liabilities.

      Section 2.9 RIGHT OF SUBROGATION AND CONTRIBUTION. If Guarantor makes a
payment in respect of the Liabilities, it shall be subrogated to the rights of
the Lenders against the Company with respect to such payment and shall have the
rights of contribution against the other Subsidiary Guarantors set forth in
Section 2.9 of the Subsidiary Guarantors' Guaranty Agreements; provided that
Subsidiary Guarantor shall not enforce its rights to any payment by way of
subrogation or by exercising its rights of contribution or reimbursement or the
right to participate in any security now or hereafter held by or for the benefit
of the Lenders until the Liabilities have been paid in full. The Guarantor
agrees that after all the Liabilities have been paid in full that if its then
current Net Payments are less than the amount of its then current Contribution
Obligation, Guarantor shall pay to the other Subsidiary Guarantors an amount
(together with any payments required of the other Subsidiary Guarantors by
Section 2.9 of each other Guaranty Agreement) such that the Net Payments made by
all Subsidiary Guarantors in respect of the Liabilities shall be shared among
all of the Subsidiary Guarantors in proportion to their respective Contribution
Percentage.

      Reference is made to the Amended and Restated Credit Agreement, dated as
of February 26, 1999 (as amended, supplemented, waived or otherwise modified
from time to time, the "CREDIT AGREEMENT"), among BENCHMARK ELECTRONICS, INC.,
as the Company, and CHASE BANK OF TEXAS, N.A., individually, as Issuing Bank,
and as Administrative Agent, and the Lenders now or hereafter parties thereto.
Unless otherwise defined herein, terms defined in the Credit Agreement and used
herein shall have the meanings given to them in the Credit Agreement.

      ______________________ (the "ASSIGNOR") and _________________ (the
"ASSIGNEE") agree as follows:

      1. The Assignor hereby irrevocably sells and assigns to the Assignee
without recourse to the Assignor, and the Assignee hereby irrevocably purchases
and assumes from the Assignor without recourse to the Assignor, as of the
Transfer Effective Date (as defined below), a percentage interest (the "ASSIGNED

obligations under the Credit Agreement and the other Financing Documents with
respect to the credit facilities provided for in the Credit Agreement (the
"ASSIGNED FACILITIES"), in a principal amount for each Assigned Facility as set
forth on SCHEDULE 1.

      2. The Assignor (a) makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or representations
made in or in connection with the Credit Agreement, any other Financing Document
or any other instrument or document furnished pursuant thereto or the execution,
legality, validity, enforceability, genuineness, sufficiency or value of the
Credit Agreement, any other Financing Document or any other instrument or
document furnished pursuant thereto, other than that it has not created any
adverse claim upon the interest being assigned by it hereunder and that such
interest is free and clear of any such adverse claim; (b) makes no
representation or warranty and assumes no responsibility with respect to the
financial condition of the Company, any of its Subsidiaries or any other obligor
or the performance or observance by the Company, any of its Subsidiaries or any
other obligor of any of their respective obligations under the Credit Agreement,
any other Financing Document or any other instrument or document furnished
pursuant hereto or thereto; and (c) attaches the Notes held by it evidencing the
Assigned Facilities and requests that the Administrative Agent exchange such
Notes for new Notes payable to the Assignee and (if the Assignor has retained
any interest in the Assigned Facilities) new Notes payable to the Assignor in
the respective amounts which reflect the assignment being made hereby (and after
giving effect to any other assignments which have become effective on the
Transfer Effective Date).1

      3. The Assignee (a) represents and warrants that it is legally authorized
to enter into this Assignment and Acceptance; (b) confirms that it has received
a copy of the Credit Agreement together with copies of the Financial Statements
and/or such other documents and information as it has deemed appropriate to make
its own credit analysis and decision to enter into this Assignment and
Acceptance; (c) agrees that it will, independently and without reliance upon the
Assignor, the Administrative Agent or any other Lender and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under the Credit
Agreement, the other Financing Documents or any other instrument or document
furnished pursuant hereto or thereto; (d) appoints and

and to exercise such power and discretion under the Credit Agreement, the other
Financing Documents or any other instrument or document furnished pursuant
hereto or thereto as are delegated to the Administrative Agent by the terms
thereof, together with such powers as are incidental thereto; (e) hereby affirms
the acknowledgments of such Assignee as a Lender contained in Section 8.3 of the
Credit Agreement; and (f) agrees that it will be bound by the provisions of the
Credit Agreement and will perform in accordance with the terms of the Credit
Agreement all the obligations which by the terms of the Credit Agreement are
required to be performed by it as a Lender, including, but not limited to, if it
is organized under the laws of a jurisdiction outside the United States, its
obligations pursuant to Section 2.20(f) of the Credit Agreement.

      4. The effective date of this Assignment and Acceptance shall be
_________________ (the "TRANSFER EFFECTIVE DATE"). Following the execution of
this Assignment and Acceptance, it will be delivered to the Administrative Agent
for acceptance by it and recording by the Administrative Agent pursuant to
Section 9.7 of the Credit Agreement, effective as of the Transfer Effective Date
(which shall not, unless otherwise agreed to by the Administrative Agent, be
earlier than five Business Days after the date of such acceptance and recording
by the Administrative Agent).

      5. Upon such acceptance and recording, from and after the Transfer
Effective Date, the Administrative Agent shall make all payments in respect of
the Assigned Interest (including payments of principal, interest, fees and other
amounts) to the Assignee whether such amounts have accrued prior to the Transfer
Effective Date or accrued subsequent to the Transfer Effective Date. The
Assignor and the Assignee shall make all appropriate adjustments in payments by
the Administrative Agent for the periods prior to the Transfer Effective Date or
with respect to the making of this assignment directly between themselves.

      6. From and after the Transfer Effective Date, (a) the Assignee shall be a
party to the Credit Agreement and, to the extent provided in this Assignment and
Acceptance, have the rights and obligations of a Lender thereunder and under the
other Financing Documents and shall be bound by the provisions thereof and (b)
the Assignor shall, to the extent provided in this Assignment and Acceptance,
relinquish its rights and be released from its obligations under the Credit
Agreement, but shall nevertheless continue to be entitled to the benefits of
Sections 2.16, 2.18, 2.20 and 9.4 thereof.

      7. Notwithstanding any other provision hereof, if the consents of the
Company and the Administrative Agent hereto are required under Section 9.7 of
the Credit Agreement, this Assignment and Acceptance shall not be effective
