   THIS LOAN AGREEMENT (this "Agreement") is made and entered into
  as of October 23, 1998 (the "Effective Date"), by and among
  OCEANEERING INTERNATIONAL, INC., a Delaware corporation
  (together with its permitted successors and assigns, herein
  called the "Borrower"); each of the lenders which is or may from
  time to time become a party hereto (individually, a "Lender"
  and, collectively, the "Lenders"); CITICORP USA, INC., as
  Documentation Agent, WELLS FARGO BANK (TEXAS), N. A., as
  Syndication Agent, and CHASE BANK OF TEXAS, NATIONAL ASSOCIATION
  ("Chase Texas"), a national banking association, as
  Administrative Agent, Lead Arranger and Book Manager (in such
  capacity, together with its successors in such capacity, the 
  "Agent").
  
       The parties hereto agree as follows:
  
  1.   Definitions.
  
       1.1  Certain Defined Terms.
  
   In this Agreement, terms defined above shall have the meanings
  ascribed to them above. Unless a particular term, word or phrase
  is otherwise defined or the context otherwise requires,
  capitalized terms, words and phrases used herein or in the Loan
  Documents (as hereinafter defined) have the following meanings
  (all definitions that are defined in this Agreement or in the
  Loan Documents in the singular have the same meanings when used
  in the plural and vice versa):
  
       Additional Interest means the aggregate of all amounts
  accrued or paid pursuant to the Notes or any of the other Loan
  Documents (other than interest on the Notes at the Stated Rate)
  which, under applicable laws, are or may be deemed to constitute
  interest on the indebtedness evidenced by the Notes or any other
  amounts owing under any Loan Document.
  
   Adjusted LIBOR means, with respect to each Interest Period
  applicable to a LIBOR Borrowing, a rate per annum equal to the
  quotient, expressed as a percentage, of (a) LIBOR with respect
  to such Interest Period divided by (b) 1.0000 minus the
  Eurodollar Reserve Requirement in effect on the first day of
  such Interest Period.
  
   Affiliate means any Person controlling, controlled by or under
  common control with any other Person.  For purposes of this
  definition, "control" (including "controlled by" and "under
  common control with") means the possession, directly or
  indirectly, of the power to direct or cause the direction of the
  management and policies of such Person, whether through the
  ownership of voting securities or otherwise.
  
       Agreement means this Loan Agreement, as it may from time to
  time be amended, modified, restated or supplemented.
  
   Annual Financial Statements means the annual financial
  statements of Borrower and its subsidiaries, including all notes
  thereto, which statements shall include a balance sheet as of
  the end of the fiscal year relating thereto and an income
  statement and a statement of cash flows for such fiscal year,
  all setting forth in comparative form the corresponding figures
  from the previous fiscal year, all prepared in conformity with
  GAAP in all material respects, and accompanied by the opinion of
  independent certified public accountants of recognized national
  standing, which shall state that such financial statements
  present fairly in all material respects the consolidated
  financial position of the applicable Persons as of the date
  thereof and the results of operations of the applicable Persons
  for the period covered thereby in conformity with GAAP.  As long
  as Borrower files an annual report on Form 10-K with the
  Securities and Exchange Commission, such report and related
  financial statements, including notes thereto and opinion of
  independent certified public accountants, included thereon shall
  be considered the "Annual Financial Statements".  
  
       Assignment and Acceptance shall have the meaning ascribed
  to such term in Section 11.6(b) hereof.
  
       Bankruptcy Code means the United States Bankruptcy Code, as
  amended, and any successor statute.
  
   Base Rate means for any day a rate per annum equal to the
  lesser of (a) the then applicable Margin Percentage from time to
  time in effect plus the greater of (1) the Prime Rate for that
  day and (2) the Federal Funds Rate for that day plus 1/2 of 1%
  or (b) the Ceiling Rate.  If for any reason Agent shall have
  determined (which determination shall be prima facie evidence of
  the correctness thereof) that it is unable to ascertain the
  Federal Funds  Rate for any reason, including, without
  limitation, the inability or failure of Agent to obtain
  sufficient quotations in accordance with the terms hereof, the
  Base Rate shall, until the circumstances giving rise to such
  inability no longer exist, be the lesser of (a) the Prime Rate
  plus the then applicable Margin Percentage from time to time in
  effect or (b) the Ceiling Rate.
  
       Base Rate Borrowing means that portion of the principal
  balance of the Loans at any time bearing interest at the Base Rate.
  
   Business Day means any day other than a day on which commercial
  banks are authorized or required to close in Houston, Texas.
  
       Capitalized Lease means any lease the obligation for
  Rentals with respect to which is required to be capitalized on a
  consolidated balance sheet of the lessee and its subsidiaries in
  accordance with GAAP.
  
       Ceiling Rate means, on any day, with respect to any Lender,
  the maximum nonusurious rate of interest, if any, permitted for
  that day under the law then applicable to such Lender, stated as
  a rate per annum.  On each day, if any, that Chapter 1D
  establishes the Ceiling Rate for any Lender, the Ceiling Rate
  for such Lender shall be the "weekly ceiling" (as defined in
  Section303 of the Texas Finance Code) for that day.  Agent may
  from time to time, as to current and future balances, implement
  any other ceiling under the Texas Finance Code or Chapter 1D by
  notice to Borrower, if and to the extent applicable to any
  Lender and permitted by the Texas Finance Code or Chapter 1D. 
  Without notice to Borrower or any other person or entity, the
  Ceiling Rate shall automatically fluctuate upward and downward
  as and in the amount by which such maximum nonusurious rate of
  interest permitted by applicable law fluctuates. 
  Notwithstanding any choice of law set forth herein or in any
  other Loan Document, to the maximum extent permitted under
  applicable laws, any Lender may elect to have the usury laws of
  another jurisdiction apply to the Note and the Loans held by
  such Lender.
  
   Change of Control shall be deemed to have occurred if any
  person (as such term is used in Section 13(d) and Section
  14(d)(2) of the Exchange Act as in effect on the date of the
  Closing) or related persons constituting a group (as such term
  is used in Rule 13d-5 under the Exchange Act), other than an
  Affiliate described on Exhibit G,
  
                         (i) become the "beneficial owners" (as
            such term is used in Rule 13d-3 under the Exchange Act
            as in effect on the date hereof), directly or

            Stock, or
  
                        (ii) acquire after the date hereof (x) the
            power to elect, appoint or cause the election or
            appointment of at least a majority of the members of
            the board of directors of Borrower, through beneficial
            ownership of the capital stock of Borrower or

  provided for in an Assignment and Acceptance Agreement (as the
  same may be reduced from time to time pursuant to Section 2.2 
  hereof).

  ended fiscal quarter of Borrower calculated by Agent as soon as
  practicable after receipt by Agent of all financial reports
  required under this Agreement with respect to such fiscal
  quarter (including a Compliance Certificate) (provided, however,
  that if the Commitment Fee Percentage is increased as a result
  of the reported Debt to Capitalization Ratio, such increase
  shall be retroactive to the date that Borrower was obligated to
  deliver such financial reports to Agent pursuant to the terms of
  this Agreement and provided further, however, that if the
  Commitment Fee Percentage is decreased as a result of the
  reported Debt to Capitalization Ratio, and such financial
  reports are delivered to Agent not more than ten (10) calendar
  days after the date required to be delivered pursuant to the
  terms of this Agreement, such decrease shall be retroactive to
  the date that Borrower was obligated to deliver such financial
  reports to Agent pursuant to the terms of this Agreement):

   2.1 Loans.  From time to time on or after the Effective Date
  and prior to the Maturity Date, each Lender shall make loans
  under this Section 2.1 to Borrower in an aggregate principal
  amount at any one time outstanding up to but not exceeding such
  Lender's Commitment Percentage of $80,000,000.  Subject to the
  conditions in this Agreement, any such Loan repaid prior to the
  Maturity Date may be reborrowed pursuant to the terms of this
  Agreement. Borrower, Agent and the Lenders agree pursuant to
  Chapter 346 ("Chapter 346") of the Texas Finance Code, that
  Chapter 346 (which relates to open-end line of credit revolving
  loan accounts) shall not apply to this Agreement, the Notes or
  any Obligation and that neither the Notes nor any Obligation
  shall be governed by Chapter 346 or subject to its provisions in
  any manner whatsoever.  The aggregate of all Loans to be made by
  the Lenders in connection with a particular borrowing shall be
  equal to the lesser of (a) the remaining unused portion of the
  Commitments or (b) a multiple of $100,000.
  
   2.2 Terminations or Reductions of  Commitments.
  
   (a) Mandatory.  On the Maturity Date, all Commitments shall be
  terminated in their entirety.
  
       (b)  Optional.  Borrower shall have the right to terminate
  or reduce the unused portion of the Commitments at any time or
  from time to time, provided that (i) Borrower shall give notice
  of each such termination or reduction to Agent as provided in
  Section 4.3 hereof and (ii) each such partial reduction shall be
  in an integral multiple of $500,000.
  
   (c) No Reinstatement.  No termination or reduction of the
  Commitments may be reinstated without the written approval of
  Agent and the Lenders.
  
   2.3 Commitment Fees.
  
       (a)  Borrower shall pay to Agent for the account of each
  Lender revolving loan commitment fees at a rate per annum equal
  to the Commitment Fee Percentage.  Such revolving loan
  commitment fees shall be computed (on the basis of the actual
  number of days elapsed in a year composed of 365 or 366 days, as
  the case may be) on each day and shall be based on the excess of
  (x) the aggregate amount of each Lender's Commitment for such
  day over (y) the aggregate unpaid principal balance of such
  Lender's Note on such day.  Accrued revolving loan commitment
  fees shall be payable in arrears on the Quarterly Dates prior to
  the Maturity Date and on the Maturity Date.
  
       (b)  All past due fees payable under this Section shall
  bear interest at the Past Due Rate.
  
   2.4 Several Obligations.  The failure of any Lender to make any
  Loan to be made by it on the date specified therefor shall not
  relieve any other Lender of its obligation to make its Loan on
  such date, but neither Agent nor any Lender shall be responsible
  or liable for the failure of any other Lender to make a Loan to
  be made by such other Lender.  Notwithstanding anything
  contained herein to the contrary, (a) no Lender shall be
  required to make or maintain Loans at any time outstanding if as
  a result the total Obligations owed to such Lender shall exceed
  the lesser of (1) such Lender's Commitment Percentage of all
  Obligations and (2) such Lender's Commitment Percentage of
  $80,000,000 and (b) if a Lender fails to make a Loan as and when
  required hereunder, then upon each subsequent event which would
  otherwise result in funds being paid to the defaulting Lender,
  the amount which would have been paid to the defaulting Lender
  shall be divided among the non-defaulting Lenders ratably
  according to their respective shares of the outstanding
  Commitment Percentages until the Obligations of each Lender
  (including the defaulting Lender) are equal to such Lender's
  Commitment Percentage of the total Obligations.
  
   2.5 Notes.  The Loans made by each Lender shall be evidenced by
  a single promissory note of Borrower in substantially the form
  of Exhibit C hereto payable to the order of such Lender in a
  principal amount equal to the Commitment of such Lender, and
  otherwise duly completed.  The promissory notes described in
  this Section are each, together with all renewals, extensions,
  modifications and replacements thereof and substitutions
  therefor, called a "Note" and collectively called the "Notes". 
  Each Lender is hereby authorized by Borrower to endorse on the
  schedule (or a continuation thereof) that may be attached to
  each Note of such Lender, to the extent applicable, the date,
  amount, type of and the applicable period of interest for each
  Loan made by such Lender to Borrower hereunder, and the amount
  of each payment or prepayment of principal of such Loan received
  by such Lender, provided that any failure by such Lender to make
  any such endorsement shall not affect the obligations of
  Borrower under such Note or hereunder in respect of such Loan.
  
   2.6 Use of Proceeds.  The proceeds of the Loans shall be used
  for working capital and general corporate purposes.  Neither
  Agent nor any Lender shall have any responsibility as to the use
  of any proceeds of the Loans.
  
  3.   Borrowings, Payments, Prepayments and Interest Options.
  
   3.1 Borrowings.  Borrower shall give Agent notice of each
  borrowing to be made hereunder as provided in Section 4.3 hereof
  and Agent shall promptly notify each Lender of such request. 
  Not later than 12:00 noon Houston time on the date specified for
  each such borrowing hereunder, each Lender shall make available
  the amount of the Loan, if any, to be made by it on such date to
  Agent at its Principal Office, in immediately available funds,
  for the account of Borrower.  Such amounts received by Agent
  will be held in an account maintained by Borrower with Agent. 
  The amounts so received by Agent shall, subject to the terms and
  conditions of this Agreement, be made available to Borrower by
  wiring or otherwise transferring, in immediately available
  funds, such amount to an account designated by Borrower and
  approved by Agent.
  
   3.2 Payments; Prepayments.
  
   (a) Optional Prepayments.  Except as provided in Section 3.3
  hereof, Borrower shall have the right to prepay, on any Business
  Day, in whole or in part, without the payment of any premium,
  penalty or fee, any Loans at any time or from time to time,
  provided that Borrower shall give Agent notice of each such
  prepayment as provided in Section 4.3 hereof.  Each optional
  prepayment on a Loan shall be in an amount equal to a minimum of
  $500,000 plus integral multiples of $100,000.
  
       (b)  Interest Payments.  Accrued and unpaid interest on the
  unpaid principal balance of the Loans shall be due and payable
  on the Interest Payment Dates.
  
       (c)  Interest on Past Due Payments.  Subject to Section
  11.7 hereof, Borrower will pay to Agent for the account of each
  Lender interest at the applicable Past Due Rate on any amount
  payable by Borrower hereunder to or for the account of such
  Lender (but, if such amount is interest, only to the extent
  legally allowed), which shall not be paid in full within five
  (5) days after the date due (whether at stated maturity, by
  acceleration or otherwise), for the period commencing on the
  expiration of such five (5) day period until the same is paid in 
  full.
  
   3.3 Interest Options
  
   (a) Options Available.  The outstanding principal balance of
  the Notes shall bear interest at the Base Rate; provided, that
  (1) subject to Section 3.2(c), all past due amounts, both
  principal and accrued and unpaid interest, shall bear interest
  at the Past Due Rate, and (2) subject to the provisions hereof,
  Borrower shall have the option of having all or any portion of
  the principal balances of the Notes from time to time
  outstanding bear interest at a Eurodollar Rate.  The records of
  Agent and each of the Lenders with respect to Interest Options,
  Interest Periods and the amounts of Loans to which they are
  applicable shall be prima facie evidence of the correctness
  thereof.  Interest on the Loans shall be calculated at the Base
  Rate except where it is expressly provided pursuant to this
  Agreement that a Eurodollar Rate is to apply.  Interest on the
  amount of each advance against the Notes shall be computed on
  the amount of that advance and from the date it is made to but
  excluding the date of repayment thereof.  Notwithstanding
  anything in this Agreement to the contrary, for the full term of
  the Notes the interest rate produced by the aggregate of all
  sums paid or agreed to be paid to the holders of the Notes for
  the use, forbearance or detention of the debt evidenced thereby
  (including all interest on the Notes at the Stated Rate plus the
  Additional Interest) shall not exceed the Ceiling Rate.
  
   (b) Designation and Conversion.  Borrower shall have the right
  to designate or convert its Interest Options in accordance with
  the provisions hereof.  Provided no Event of Default has
  occurred and is continuing and subject to the last sentence of
  Section 3.3(a) and the provisions of Section 3.3(c), Borrower
  may elect to have a Eurodollar Rate apply or continue to apply
  to all or any portion of the principal balance of the Notes. 
  Each change in Interest Options shall be a conversion of the
  rate of interest applicable to the specified portion of the
  Loans, but such conversion shall not change the respective
  outstanding principal balances of the Notes.  The Interest
  Options shall be designated or converted in the manner provided 
  below:
  
       (i)  Borrower shall give Agent telephonic notice, promptly
            confirmed by a Rate Designation Notice (and Agent
            shall promptly inform each Lender thereof).  Each such
            telephonic and written notice shall specify the amount
            of the Loan which is the subject of the designation,
            if any; the amount of borrowings into which such
            borrowings are to be converted or for which an
            Interest Option is designated; the proposed date for
            the designation or conversion and the Interest Period
            or Periods, if any, selected by Borrower.  Such
            telephonic notice shall be irrevocable and shall be
            given to Agent no later than the applicable Rate
            Designation Date.
  
       (ii)      No more than eight (8) LIBOR Borrowings shall be
                 in effect at any time. 
  
       (iii)     Each advance, designation or conversion of a
                 LIBOR Borrowing shall occur on a LIBOR Business Day.
  
       (iv)      Except as provided in Section 3.3(c) hereof, no
                 LIBOR Borrowing may be converted to a Base Rate
                 Borrowing or another LIBOR Borrowing on any day
                 other than the last day of the applicable
                 Interest Period.
  
       (v)  Each request for a LIBOR Borrowing shall be in the
            amount equal to $500,000 or an integral multiple of
            $100,000 in excess thereof.
  
       (vi)      Subject to Section 3.3(c)(i), each designation of
                 an Interest Option with respect to the Notes
                 shall apply to all of the Notes ratably in
                 accordance with their respective outstanding
                 principal balances.  If any Lender assigns an
                 interest in its Note when any LIBOR Borrowing is
                 outstanding with respect thereto, then such
                 assignee shall have its ratable interest in such
                 LIBOR Borrowing.
  
   (c) Special Provisions Applicable to LIBOR Borrowings.
  
   (i) Options Unlawful.  If the adoption of any applicable Legal
  Requirement after the Effective Date or any change after the
  Effective Date in any applicable Legal Requirement or in the
  interpretation or administration thereof by any Governmental
  Authority or compliance by any Lender with any request or
  directive (whether or not having the force of law) issued after
  the Effective Date by any central bank or other Governmental
  Authority shall at any time make it unlawful or impossible for
  any Lender to permit the establishment of or to maintain any
  LIBOR Borrowing, the commitment of such Lender to establish such
  LIBOR Borrowing shall forthwith be canceled and Borrower shall
  on the last day the Interest Period relating to any outstanding
  LIBOR Borrowing (or within such earlier period as may be
  required by applicable law) (1) convert the LIBOR Borrowing of
  such Lender to a Base Rate Borrowing; (2) pay all accrued and
  unpaid interest to date on the amount so converted; and (3) pay
  any amounts required to compensate each Lender for any
  additional cost or expense which any Lender may incur as a
  result of such adoption of or change in such Legal Requirement
  or in the interpretation or administration thereof and any
  Funding Loss which any Lender may incur as a result of such
  conversion.  If, when Agent so notifies Borrower, Borrower has
  given a Rate Designation Notice specifying a LIBOR Borrowing but
  the selected Interest Period has not yet begun, as to the
  applicable Lender such Rate Designation Notice shall be deemed
  to be of no force and effect, as if never made, and the balance
  of the Loans made by such Lender specified in such Rate
  Designation Notice shall bear interest at the Base Rate until a
  different available Interest Option shall be designated in
  accordance herewith.
  
   (ii)     Increased Cost of Borrowings.  Subject to Section
  11.15, if the adoption after the Effective Date of any
  applicable Legal Requirement or any change after the Effective
  Date in any applicable Legal Requirement or in the
  interpretation or administration thereof by any Governmental
  Authority or compliance by any Lender with any request or
  directive (whether or not having the force of law) issued after
  the Effective Date by any central bank or Governmental Authority
  shall at any time as a result of any portion of the principal
  balances of the Notes being maintained on the basis of a
  Eurodollar Rate:
  
        (1)      subject any Lender to any Taxes, or any deduction
                 or withholding for any Taxes, on or from any
                 payment due under any LIBOR Borrowing or other
                 amount due hereunder, other than income and
                 franchise taxes of the United States or its
                 political subdivisions or such other jurisdiction
                 in which the applicable Lender has any office or
                 applicable lending office; or
  
        (2)      change the basis of taxation of payments due from
                 Borrower to any Lender under any LIBOR Borrowing
                 (otherwise than by a change in the rate of
                 taxation of the gross revenues or overall net
                 income of such Lender); or
  
        (3)      impose, modify, increase or deem applicable any
                 reserve requirement (excluding that portion of
                 any reserve requirement included in the
                 calculation of the applicable Eurodollar Rate),
                 special deposit requirement or similar
                 requirement (including, but not limited to, state
                 law requirements) against assets of any Lender,
                 or against deposits with any Lender, or against
                 loans made by any Lender, or against any other
                 funds, obligations or other Property owned or
                 held by any Lender; or
  
            (4)  impose on any Lender any other condition
                 regarding any LIBOR Borrowing;
  
  and the result of any of the foregoing is to increase the cost
  to any Lender of agreeing to make or of making, renewing or
  maintaining such LIBOR Borrowing, or reduce the amount of
  principal or interest received by any Lender, then, within 15
  Business Days after demand by Agent (accompanied by a statement
  setting forth in reasonable detail the applicable Lender's basis
  therefor), Borrower shall pay to Agent additional amounts which
  shall compensate each Lender for such increased cost or reduced
  amount.  The determination by any Lender of the amount of any
  such increased cost, increased reserve requirement or reduced
  amount shall be prima facie evidence of the correctness thereof.
   Borrower shall have the right, if it receives from Agent any
  notice referred to in this paragraph, upon three Business Days'
  notice to Agent (which shall notify each affected Lender),
  either (i) to repay in full (but not in part) any borrowing with
  respect to which such notice was given, together with any
  accrued interest thereon, or (ii) to convert the LIBOR Borrowing
  which is the subject of the notice to a Base Rate Borrowing;
  provided, that any such repayment or conversion shall be
  accompanied by payment of (x) the amount required to compensate
  each Lender for the increased cost or reduced amount referred to
  in the preceding paragraph; (y) all accrued and unpaid interest
  to date on the amount so repaid or converted, and (z) any
  Funding Loss which any Lender may incur as a result of such
  repayment or conversion.  Each Lender will notify Borrower
  through Agent of any event occurring after the date of this
  Agreement which will entitle such Lender to compensation
  pursuant to this Section as promptly as practicable after it
  obtains knowledge thereof and determines to request such
  compensation, and (if so requested by Borrower through Agent)
  will designate a different lending office of such Lender for the
  applicable LIBOR Borrowing or will take such other action as
  Borrower may reasonably request if such designation or action is
  consistent with the internal policy of such Lender and legal and
  regulatory restrictions, will avoid the need for, or reduce the
  amount of, such compensation and will not, in the sole opinion
  of such Lender, be disadvantageous to such Lender (provided that
  such Lender shall have no obligation so to designate a different
  lending office which is located in the United States of America).
  
       (iii) Inadequacy of Pricing and Rate Determination.  If,
  for any reason with respect to any Interest Period, Agent (or,
  in the case of clause 3 below, the applicable Lender) shall have
  reasonably  determined that:
  
            (1)  Agent is unable through its customary general
                 practices to determine any applicable Eurodollar
                 Rate, or
  
            (2)  by reason of circumstances affecting the
                 applicable market, generally, Agent is not being
                 offered deposits in United States dollars in such
                 market, for the applicable Interest Period and in
                 an amount equal to the amount of any applicable
                 LIBOR Borrowing requested by Borrower, or
  
            (3)  any applicable Eurodollar Rate will not
                 adequately and fairly reflect the cost to any
                 Lender of making and maintaining such LIBOR
                 Borrowing hereunder for any proposed Interest 
                 Period,
  
  then Agent shall give Borrower notice thereof and thereupon, (A)
  any Rate Designation Notice previously given by Borrower
  designating the applicable LIBOR Borrowing which has not
  commenced as of the date of such notice from Agent shall be
  deemed for all purposes hereof to be of no force and effect, as
  if never given, and (B) until Agent shall notify Borrower that
  the circumstances giving rise to such notice from Agent no
  longer exist, each Rate Designation Notice requesting the
  applicable Eurodollar Rate shall be deemed a request for a Base
  Rate Borrowing, and any applicable LIBOR Borrowing then
  outstanding shall be converted, without any notice to or from
  Borrower, upon the termination of the Interest Period then in
  effect with respect to it, to a Base Rate Borrowing.
  
   (iv)     Funding Losses.  Borrower shall indemnify each Lender
  against and hold each Lender harmless from any Funding Loss. 
  Subject to Section 11.15, this indemnity shall survive the
  payment of the Notes.  Within 15 Business Days after demand by
  Agent (accompanied by a certificate of such Lender setting forth
  in reasonable detail the amount and calculation of the amount
  claimed as to any Funding Losses, which shall be prima facie
  evidence of the correctness thereof), Borrower shall pay to
  Agent, for the account of such Lender, the amount of such
  Funding Losses.
  
   (d) Funding Offices; Adjustments Automatic; Calculation Year. 
  Any Lender may, if it so elects, fulfill its obligation as to
  any LIBOR Borrowing by causing a branch or affiliate of such
  Lender to make such Loan and may transfer and carry such Loan
  at, to or for the account of any branch office or affiliate of
  such Lender; provided, that in such event for the purposes of
  this Agreement such Loan shall be deemed to have been made by
  such Lender and the obligation of Borrower to repay such Loan
  shall nevertheless be to such Lender and shall be deemed held by
  it for the account of such branch or affiliate.  Without notice
  to Borrower or any other Person, each rate required to be
  calculated or determined under this Agreement shall
  automatically fluctuate upward and downward in accordance with
  the provisions of this Agreement.  Interest at the Prime Rate
  shall be computed on the basis of the actual number of days
  elapsed in a year consisting of 365 or 366 days, as the case may
  be.  All other interest required to be calculated or determined
  under this Agreement shall be computed on the basis of the
  actual number of days elapsed in a year consisting of 360 days,
  unless the Ceiling Rate would thereby be exceeded, in which
  event, to the extent necessary to avoid exceeding the Ceiling
  Rate, the applicable interest shall be computed on the basis of
  the actual number of days elapsed in the applicable calendar
  year in which accrued.
  
       (e)  Funding Sources.  Notwithstanding any provision of
  this Agreement to the contrary, each Lender shall be entitled to
  fund and maintain its funding of all or any part of the Loans in
  any manner it sees fit, it being understood, however, that for
  the purposes of this Agreement all determinations hereunder
  shall be made as if each Lender had actually funded and
  maintained each LIBOR Borrowing during each Interest Period
  through the purchase of deposits having a maturity corresponding
  to such Interest Period and bearing an interest rate equal to
  the Eurodollar Rate for such Interest Period.
  
  4.   Payments; Pro Rata Treatment; Computations, Etc.
  
   4.1 Payments.
  
       (a)  Except to the extent otherwise provided herein, all
  payments of principal, interest  and other amounts to be made by
  Borrower hereunder, under the Notes and under the other Loan
  Documents shall be made in Dollars, in immediately available
  funds, to Agent at the Principal Office (or in the case of a
  successor Agent, at the principal office of such successor Agent
  in the United States), not later than 11:00 a.m. Houston time on
  the date on which such payment shall become due (each such
  payment made after such time on such due date to be deemed to
  have been made on the next succeeding Business Day).
  
   (b) Borrower shall, at the time of making each payment
  hereunder, under any Note or under any other Loan Document,
  specify to Agent the Loans or other amounts payable by Borrower
  hereunder or thereunder to which such payment is to be applied. 
  Each payment received by Agent hereunder, under any Note or
  under any other Loan Document for the account of a Lender shall
  be paid promptly to such Lender, in immediately available funds.
   If Agent fails to send to any Lender the applicable amount by
  the close of business on the date any such payment is received
  by Agent if such payment is received prior to 11:00 a.m. Houston
  time (or on the next succeeding Business Day with respect to
  payments which are received after 11:00 a.m. Houston time),
  Agent shall pay to the applicable Lender interest on such amount
  from such date at the Federal Funds Rate.  Borrower, the Lenders
  and Agent acknowledge and agree that this provision and each
  other provision of this Agreement or any of the other Loan
  Documents relating to the application of amounts in payment of
  the Obligations shall be subject to the provisions of Section
  4.2(d) regarding pro rata application of amounts after an Event
  of Default shall have occurred and be continuing.
  
   (c) If the due date of any payment hereunder or under any Note
  falls on a day which is not a Business Day, the due date for
  such payments (except as otherwise provided in clause (2) of the
  definition of "Interest Period") shall be extended to the next
  succeeding Business Day and interest shall be payable for any
  principal so extended for the period of such extension.
  
   (d) All payments by Borrower hereunder or under any other Loan
  Document shall be made free and clear of and without deduction
  for or on account of any present or future income, stamp, or
  other taxes, fees, duties, withholding or other charges of any
  nature whatsoever imposed by any taxing authority excluding in
  the case of Agent and each Lender taxes imposed on or measured
  by its net income or franchise taxes imposed by the jurisdiction
  in which it is organized or through which it acts for purposes
  of this Agreement (such non-excluded items being hereinafter
  referred to as "Taxes").  If as a result of any change in law
  (or the interpretation thereof) after the date that Agent or the
  applicable Lender became a party to this Agreement, any
  withholding or deduction from any payment to be made to, or for
  the account of, such Person by Borrower hereunder or under any
  other Loan Document is required in respect of any Taxes pursuant
  to any applicable law, rule, or regulation, then Borrower will
  (i) pay to the relevant authority the full amount required to be
  so withheld or deducted; (ii) to the extent available, promptly
  forward to Agent an official receipt or other documentation
  reasonably satisfactory to Agent evidencing such payment to such
  authority; and (iii) pay to Agent, for the account of each
  affected Person, such additional amount or amounts as are
  necessary to ensure that the net amount actually received by
  such Lender will equal the full amount such Person would have
  received had no such withholding or deduction been required. 
  Each such Person shall determine such additional amount or
  amounts payable to it (which determination shall be prima facie
  evidence of the correctness thereof).  If Agent or any Lender
  becomes aware that any such withholding or deduction from any
  payment to be made by Borrower hereunder or under any other Loan
  Document is required, then such Person shall promptly notify
  Agent and Borrower thereof stating the reasons therefor and the
  additional amount required to be paid under this Section.  Each
  Lender shall execute and deliver to Agent and Borrower such
  forms as it may be required to execute and deliver pursuant to
  Section 11.13 hereof.  To the extent that any such withholding
  or deduction results from the failure of a Lender to provide a
  form required by Section 11.13 hereof (unless such failure is
  due to some prohibition under applicable Legal Requirements),
  Borrower shall have no obligation to pay the additional amount
  required by clause (iii) above.  Anything in this Section
  notwithstanding, if any Lender elects to require payment by
  Borrower of any material amount under this Section, Borrower
  may, within 60 days after the date of receiving notice thereof
  and so long as no Default shall have occurred and be continuing,
  elect to terminate such Lender as a party to this Agreement;
  provided that, concurrently with such termination Borrower shall
  (i) if Agent and each of the other Lenders shall consent, pay
  that Lender all principal, interest and fees and other amounts
  owed to such Lender through such date of termination or (ii)
  have arranged for another financial institution approved by
  Agent (such approval not to be unreasonably withheld or delayed)
  as of such date, to become a substitute Lender for all purposes
  under this Agreement in the manner provided in Section 11.6;
  provided further that, prior to substitution for any Lender,
  Borrower shall have given written notice to Agent of such
  intention and the Lenders shall have the option, but no
  obligation, for a period of 60 days after receipt of such
  notice, to increase their Commitments in order to replace the
  affected Lender in lieu of such substitution.
  
   4.2 Pro Rata Treatment.  Except to the extent otherwise
  provided herein:  (a) each borrowing from the Lenders under
  Section 2.1 hereof shall be made ratably from the Lenders in
  accordance with their respective Commitments; (b) each payment
  of revolving loan commitment fees shall be made for the account
  of the Lenders, and each termination or reduction of the
  Commitments of the Lenders under Section 2.2 hereof shall be
  applied, pro rata, according to the Lenders' respective
  Commitments, and (c) each payment by Borrower of principal of or
  interest on the Loans shall be made to Agent for the account of
  the Lenders pro rata in accordance with the respective unpaid
  principal amounts of such Loans held by the Lenders.
  
   4.3 Certain Actions, Notices, Etc.  Notices to Agent of any
  termination or reduction of Commitments and of borrowings and
  optional prepayments of Loans shall be irrevocable and shall be
  effective only if received by Agent not later than 11:00 a.m.
  Houston time on the number of Business Days prior to the date of
  the relevant termination, reduction, borrowing and/or prepayment
  specified below:
  
                                    Number of Business Days
                                          Prior Notice
  
       Termination or Reduction of
       Commitments                              3
  
       Loan repayment                           1
  
       Borrowing at the Base Rate               same day
  
       Selection of a Eurodollar Rate           3 LIBOR
                                                Business Days
  
  
  Each such notice of termination or reduction shall specify the
  amount of the applicable Commitment to be terminated or reduced.
   Each such notice of borrowing or prepayment shall specify the
  amount of the Loans to be borrowed or prepaid and the date of
  borrowing or prepayment (which shall be a Business Day).  Agent
  shall promptly notify the affected Lenders of the contents of
  each such notice.
  
   4.4 Non-Receipt of Funds by Agent.  Unless Agent shall have
  been notified by a Lender or Borrower (the "Payor") prior to the
  date on which such Lender is to make payment to Agent of the
  proceeds of a Loan to be made by it hereunder or Borrower is to
  make a payment to Agent for the account of one or more of the
  Lenders, as the case may be (such payment being herein called
  the "Required Payment"), which notice shall be effective upon
  receipt, that the Payor does not intend to make the Required
  Payment to Agent, Agent may assume that the Required Payment has
  been made and may, in reliance upon such assumption (but shall
  not be required to), make the amount thereof available to the
  intended recipient on such date and, if the Payor has not in
  fact made the Required Payment to Agent, the recipient of such
  payment shall, on demand, pay to Agent the amount made available
  by Agent, together with interest thereon in respect of the
  period commencing on the date such amount was so made available
  by Agent until the date Agent recovers such amount at a rate per
  annum equal to the Federal Funds Rate for such period.
  
   4.5 Sharing of Payments, Etc.  If a Lender shall obtain payment
  of any principal of or interest on any Loan made by it under
  this Agreement or on any other Obligation then due to such
  Lender hereunder, through the exercise of any right of set-off
  (including, without limitation, any right of setoff or Lien
  granted under Section 9.2 hereof), banker's lien, counterclaim
  or similar right or otherwise, it shall promptly purchase from
  the other Lenders participations in the Loans made, or other
  Obligations held, by the other Lenders in such amounts, and make
  such other adjustments from time to time as shall be equitable
  to the end that all the Lenders shall share the benefit of such
  payment (net of any expenses which may be incurred by such
  Lender in obtaining or preserving such benefit) pro rata in
  accordance with the unpaid Obligations then due to each of them;
  provided, however, that if all or any portion of such excess
  payment is thereafter recovered from such purchasing Lender,
  such purchase from each Lender shall be rescinded and such
  Lender shall repay to the purchasing Lender the purchase price
  to the extent of such recovery together with an amount equal to
  such Lender's ratable share (according to the proportion of (i)
  the amount of such Lender's required repayment to (ii) the total
  amount so recovered from the purchasing Lender) of any interest
  or other amount paid or payable by the purchasing Lender in
  respect of the total amount so recovered.  To such end all the
  Lenders shall make appropriate adjustments among themselves (by
  the resale of participations sold or otherwise) if such payment
  is rescinded or must otherwise be restored.  Borrower agrees, to
  the fullest extent it may effectively do so under applicable
  law, that any Lender so purchasing a participation in the Loans
  made, or other Obligations held, by other Lenders may exercise
  all rights of set-off, bankers' lien, counterclaim or similar
  rights with respect to such participation as fully as if such
  Lender were a direct holder of Loans or other Obligations in the
  amount of such participation.  Nothing contained herein shall
  require any Lender to exercise any such right or shall affect
  the right of any Lender to exercise, and retain the benefits of
  exercising, any such right with respect to any other
  indebtedness or obligation of Borrower.
  
  5.   Conditions Precedent.
  
   5.1 Initial Loans .  The obligation of each Lender to make its
  initial Loans hereunder is subject to the following conditions
  precedent, each of which shall have been fulfilled or waived to
  the satisfaction of Agent:
  
       (a)  Authorization and Status.  Agent shall have received
  (i) copies of the Organizational Documents of Borrower certified
  as true and correct by its secretary, assistant secretary or
  other equivalent officer, (ii) evidence reasonably satisfactory
  to Agent of all action taken by Borrower authorizing the
  execution, delivery and performance of the Loan Documents and
  all other documents related to this Agreement to which it is a
  party (including, without limitation, a certificate of the
  secretary, assistant secretary or other equivalent officer of
  each such party which is a corporation setting forth the
  resolutions of its Board of Directors authorizing the
  transactions contemplated thereby), and (iii) such certificates
  as may be appropriate to demonstrate the qualification and good
  standing of Borrower in the jurisdiction of its organization and
  in each other jurisdiction where the failure in which to qualify
  could reasonably be expected to have a Material Adverse Effect.
  
       (b)  Incumbency.  Borrower shall have delivered to Agent a
  certificate in respect of the name and signature of each of the
  officers (i) who is authorized to sign on its behalf the
  applicable Loan Documents to which it is a party related to any
  Loan and (ii) who will, until replaced by another officer or
  officers duly authorized for that purpose, act as its
  representative for the purposes of signing documents and giving
  notices and other communications in connection with any Loan. 
  Agent and each Lender may conclusively rely on such certificates
  until they receive notice in writing from Borrower to the contrary.
  
       (c)  Notes.  Agent shall have received the appropriate
  Notes of Borrower for each Lender, duly completed and executed.
  
       (d)  Loan Documents.  Borrower shall have duly executed and
  delivered the Loan Documents to which it is a party (in such
  number of copies as Agent shall have requested).  Each such Loan
  Document shall be in substantially the form furnished to the
  Lenders prior to their execution of this Agreement, together
  with such changes therein as Agent may approve.
  
       (e)  Fees and Expenses. Borrower shall have paid to Agent
  all unpaid fees in the amounts previously agreed upon in writing
  among Borrower and Agent.
  
       (f)  Opinions of Counsel.  Agent shall have received such
  opinions of counsel to Borrower as Agent shall reasonably
  request with respect to Borrower and the Loan Documents.
  
       (g)  Consents.  Agent shall have received evidence
  reasonably satisfactory to the Majority Lenders that all
  material consents of each Governmental Authority and of each
  other Person, if any, reasonably required in connection with (a)
  the Loans and (b) the execution, delivery and performance of
  this Agreement and the other Loan Documents have been
  satisfactorily obtained.
  
       (h)  Other Documents.  Agent shall have received such other
  documents consistent with the terms of this Agreement and
  relating to the transactions contemplated hereby as Agent may
  reasonably request.
  
   5.2 All Loans.  The obligation of each Lender to make any Loan
  to be made by it hereunder is subject to: (a) the accuracy, in
  all material respects, on the date of such Loan of all
  representations and warranties of Borrower contained in this
  Agreement and the other Loan Documents, except to the extent
  expressly limited to an earlier date; (b) Agent shall have
  received the following, all of which shall be duly executed and
  in Proper Form: (1) a Request for Extension of Credit as to the
  Loan no later than 10:00 a.m. Houston time on the Business Day
  on which such Request for Extension of Credit must be given
  under Section 4.3 hereof and (2) such other documents as Agent
  may reasonably require; (c) prior to the making of such Loan,
  there shall have occurred no event which could reasonably be
  expected to have a Material Adverse Effect; (d) no Default or
  Event of Default shall have occurred and be continuing, and (e) 
  the making of such Loan shall not be illegal or prohibited by
  any Legal Requirement.  The submission by Borrower of a Request
  for Extension of Credit shall be deemed to be a representation
  and warranty that the conditions precedent to the applicable
  Loan have been satisfied.
  
  6.   Representations and Warranties.
  
   To induce Agent and the Lenders to enter into this Agreement
  and to make the Loans, Borrower represents and warrants (such
  representations and warranties to survive any investigation and
  the making of the Loans) to the Lenders and Agent as follows:
  
   6.1 Organization.  Borrower and each of its Restricted
  Subsidiaries (a) is duly organized, validly existing and in good
  standing under the laws of the jurisdiction of its organization;
  (b) has all necessary power and authority to conduct its
  business as presently conducted, and (c) is duly qualified to do
  business and in good standing in the jurisdiction of its
  organization and in all jurisdictions in which the failure to so
  qualify could reasonably be expected to have a Material Adverse 
  Effect.
  
   6.2 Financial Statements.  Borrower has furnished to Agent (i)
  audited financial statements (including a balance sheet) as to
  Borrower which fairly present in all material respects, in
  accordance with GAAP, the consolidated financial condition and
  the results of operations of Borrower and its Subsidiaries as of
  the end of the fiscal year ended March 31, 1998 and (ii)
  unaudited financial statements (including a balance sheet) as to
  Borrower which fairly present in all material respects, in
  accordance with GAAP (subject to year-end adjustments and the
  absence of notes), the consolidated financial condition and the
  results of operations of Borrower and its Subsidiaries as of the
  end of the fiscal quarter ended June 30, 1998.  No events,
  conditions or circumstances have occurred from the date that the
  financial statements were delivered to Agent through the
  Effective Date which would cause said financial statements to be
  misleading in any material respect.  There are no material
  instruments or liabilities which should be reflected in such
  financial statements provided to Agent which are not so
  reflected that are necessary in order for such financial
  statement presentation to conform to GAAP.   Since March 31,
  1998, no event has occurred and no circumstance has arisen which
  could reasonably be expected to cause a Material Adverse Effect.
  
   6.3 Enforceable Obligations; Authorization.  The Loan Documents
  are legal, valid and binding obligations of Borrower,
  enforceable in accordance with their respective terms, except as
  may be limited by bankruptcy, insolvency and other similar laws
  and judicial decisions affecting creditors' rights generally and
  by general equitable principles.  The execution, delivery and
  performance of the Loan Documents by Borrower  (a) have all been
  duly authorized by all necessary action; (b) are within the
  corporate power and authority of Borrower; (c) do not and will
  not contravene or violate any Legal Requirement applicable to
  Borrower or the Organizational Documents of Borrower, the
  contravention or violation of which could reasonably be expected
  to have a Material Adverse Effect; (d) do not and will not
  result in the breach of, or constitute a default under, any
  material agreement or instrument by which Borrower or any of its
  Property may be bound, and (e) do not and will not result in the
  creation of any Lien upon any Property of Borrower, except in
  favor of Agent or as expressly contemplated herein or therein. 
  All necessary permits, registrations and consents for such
  making and performance have been obtained.
  
       6.4  Other Debt.  Neither Borrower nor any its Restricted
  Subsidiaries is in default in the payment of any other
  Indebtedness or under any agreement, mortgage, deed of trust,
  security agreement or lease to which it is a party and which
  default could reasonably be expected to have a Material Adverse 
  Effect.
  
   6.5 Litigation.  There is no litigation or administrative
  proceeding, to the knowledge of any executive officer of
  Borrower, pending or threatened against, nor any outstanding
  judgment, order or decree against, Borrower or any of its
  Restricted Subsidiaries before or by any Governmental Authority
  which does or could reasonably be expected to have a Material
  Adverse Effect.  Neither Borrower nor any its Restricted
  Subsidiaries is in default with respect to any judgment, order
  or decree of any Governmental Authority where such default could
  reasonably be expected to have a Material Adverse Effect.
  
   6.6 Taxes.  Borrower and each of its Restricted Subsidiaries
  has filed all tax returns required to have been filed and paid
  all taxes shown thereon to be due, except those for which
  extensions have been obtained and those which are being
  contested in good faith or where the failure to make required
  filings or pay required taxes could not reasonably be expected
  to have a Material Adverse Effect.
  
   6.7 Regulations U and X.  None of the proceeds of any Loan will
  be used for the purpose of purchasing or carrying directly or
  indirectly any margin stock or for any other purpose would
  constitute this transaction a "purpose credit" within the
  meaning of Regulations U and X of the Board of Governors of the
  Federal Reserve System, as any of them may be amended from time
  to time.
  
   6.8 Subsidiaries.  As of the Effective Date, Borrower has no
  Subsidiaries other than as set forth on Exhibit F hereto.  There
  are no Unrestricted Subsidiaries of Borrower as of the Effective 
  Date.
  
   6.9 No Untrue or Misleading Statements.  No document,
  instrument or other writing furnished to the Lenders by or on
  behalf of Borrower in connection with the transactions
  contemplated in any Loan Document contains any untrue material
  statement of fact or omits to state any such fact necessary to
  make the representations, warranties and other statements
  contained herein or in such other document, instrument or
  writing not misleading in any material respect.
  
       6.10 ERISA.  With respect to each Plan, Borrower and each
  member of the Controlled Group have fulfilled their obligations,
  including obligations under the minimum funding standards of
  ERISA and the Code and are in compliance in all material
  respects with the provisions of ERISA and the Code.  No event
  has occurred which could result in a liability of Borrower or
  any member of the Controlled Group to the PBGC or a Plan (other
  than to make contributions in the ordinary course) could
  reasonably be expected to have a Material Adverse Effect.  There
  have not been any nor are there now existing any events or
  conditions that would cause the Lien provided under Section 4068
  of ERISA to attach to any Property of Borrower or any member of
  the Controlled Group.  Unfunded Liabilities as of the date
  hereof are not reasonably expected to result in a Material
  Adverse Effect.  No "prohibited transaction" has occurred with
  respect to any Plan.
  
       6.11 Investment Company Act.  Neither Borrower nor any its
  Restricted Subsidiaries is an investment company within the
  meaning of the Investment Company Act of 1940, as amended, or,
  directly or indirectly, controlled by or acting on behalf of any
  Person which is an investment company, within the meaning of
  said Act.
  
       6.12 Public Utility Holding Company Act.  Neither Borrower
  nor any its Restricted Subsidiaries is an "affiliate" or a
  "subsidiary company" of a "public utility company," or a

  applicable to it, except to the extent that the failure to
  comply therewith could not reasonably be expected to have a
  Material Adverse Effect.
  
       6.15 Environmental Matters.  Borrower and each of its
  Restricted Subsidiaries has, to the best knowledge of their
  respective executive officers, obtained and maintained in effect
  all Environmental Permits (or the applicable Person has
  initiated the necessary steps to transfer the Environmental
  Permits into its name or obtain such permits), the failure to
  obtain which could reasonably be expected to have a Material
  Adverse Effect.  Borrower and each of its Restricted
  Subsidiaries and their Properties, business and operations have
  been and are, to the best knowledge of their respective
  executive officers, in compliance with all applicable
  Requirements of Environmental Law and Environmental Permits the
  failure to comply with which could reasonably be expected to

  Restricted Subsidiaries and their Properties, business and
  operations are not subject to any (A) Environmental Claims or

  officers (after making reasonable inquiry of the personnel and
  records of their respective Corporations), Environmental
  Liabilities, in either case direct or contingent, arising from
  or based upon any act, omission, event, condition or
  circumstance occurring or existing on or prior to the date
  hereof which could reasonably be expected to have a Material
  Adverse Effect.  None of the officers of Borrower or any of its
  Restricted Subsidiaries has received any notice of any violation
  or alleged violation of any Requirements of Environmental Law or
  Environmental Permit or any Environmental Claim in connection
  with its Properties, liabilities, condition (financial or
  otherwise), business or operations which could reasonably be
  expected to have a Material Adverse Effect.  Borrower does not
  know of any event or condition with respect to currently enacted
  Requirements of Environmental Laws presently scheduled to become
  effective in the future with respect to any of the Properties of
  Borrower or any of its Restricted Subsidiaries which could
  reasonably be expected to have a Material Adverse Effect, for
  which good faith provisions have not been made by Borrower or
  such Restricted Subsidiary in its business plan and projections
  of financial performance.

  capital adequacy, or any change therein after the Effective
  Date, or any change in the interpretation or administration
  thereof after the Effective Date by any Governmental Authority,
  central bank or comparable agency charged with the
  interpretation or administration thereof, or compliance by any
  Lender with any request or directive after the Effective Date
  regarding capital adequacy (whether or not having the force of
  law) of any such Governmental Authority, central bank or
  comparable agency has or would have the effect of reducing the
  rate of return on the capital of such Lender or any corporation
  controlling such Lender as a consequence of its obligations
  hereunder, under the Notes or other Obligations held by it to a
  level below that which such Lender or such corporation could
  have achieved but for such adoption, change or compliance
  (taking into consideration such Lender's policies with respect
  to capital adequacy) by an amount deemed by such Lender or such
  corporation to be material, then from time to time, upon
  satisfaction of the conditions precedent set forth in this
  Section, after demand by such Lender (with a copy to Agent) as
  provided below, pay (subject to Sections 11.7 and 11.15 hereof)
  to such Lender such additional amount or amounts as will
  compensate such Lender or such corporation for such reduction. 
  The certificate of any Lender setting forth such amount or
  amounts as shall be necessary to compensate it and the basis
  thereof and reasons therefor shall be delivered as soon as
  practicable to Borrower and shall be prima facie evidence of the
  correctness thereof.  Borrower shall pay the amount shown as due
  on any such certificate within fifteen (15) Business Days after
  the delivery of such certificate.  In preparing such
  certificate, a Lender may employ such assumptions and
  allocations of costs and expenses as it shall in good faith deem
  reasonable and may use any reasonable averaging and attribution 
  method.

  (ii) if requested by Agent, promptly after the filing thereof
  with the United States Secretary of Labor or the PBGC or the
  Internal Revenue Service, copies of each annual and other report
  with respect to each Plan or any trust created thereunder, (iii)
  immediately upon becoming aware of the occurrence of any
  "reportable event," as such term is defined in Section 4043 of
  ERISA, for which the disclosure requirements of Regulation
  Section 2615.3 promulgated by the PBGC have not been waived, or
  of any "prohibited transaction," as such term is defined in
  Section 4975 of the Code, in connection with any Plan or any
  trust created thereunder, a written notice signed by an
  authorized officer of Borrower or the applicable member of the
  Controlled Group specifying the nature thereof, what action
  Borrower or the applicable member of the Controlled Group is
  taking or proposes to take with respect thereto, and, when
  known, any action taken by the PBGC, the Internal Revenue
  Service or the Department of Labor with respect thereto, (iv)
  promptly after the filing or receiving thereof by Borrower or
  any member of the Controlled Group of any notice of the
  institution of any proceedings or other actions which may result
  in the termination of any Plan, and (v) each request for waiver
  of the funding standards or extension of the amortization
  periods required by Sections 303 and 304 of ERISA or Section 412
  of the Code promptly after the request is submitted by Borrower
  or any member of the Controlled Group to the Secretary of the
  Treasury, the Department of Labor or the Internal Revenue
  Service, as the case may be.  To the extent required under
  applicable statutory funding requirements, Borrower will fund,
  or will cause the applicable member of the Controlled Group to
  fund, all current service pension liabilities as they are
  incurred under the provisions of all Plans from time to time in
  effect, and comply with all applicable provisions of ERISA, in
  each case, except to the extent that failure to do the same
  could not reasonably be expected to have a Material Adverse
  Effect.  Borrower covenants that it shall and shall cause each
  member of the Controlled Group to (1) make contributions to each
  Plan in a timely manner and in an amount sufficient to comply
  with the contribution obligations under such Plan and the
  minimum funding standards requirements of ERISA; (2) prepare and
  file in a timely manner all notices and reports required under
  the terms of ERISA including but not limited to annual reports;
  and (3) pay in a timely manner all required PBGC premiums, in
  each case, except to the extent that failure to do the same
  could not reasonably be expected to have a Material Adverse Effect.

  proper functioning, in and following the year 2000, of (i)
  Borrower's and any of its Restricted Subsidiaries' computer
  systems and (ii) equipment containing embedded microchips
  (including systems and equipment supplied by others or with
  which Borrower's and any of its Restricted Subsidiaries' systems
  interface) and the testing of all such systems and equipment
  will be completed by January 1, 1999, except to the extent such
  failure is not reasonably expected to result in a Material
  Adverse Effect.  The cost to Borrower and its Restricted
  Subsidiaries of such reprogramming and testing and of reasonably
  foreseeable consequences of year 2000 to Borrower and its
  Restricted Subsidiaries (including, without limitation,
  reprogramming errors and failure of others' systems or
  equipment) will not result in an Event of Default or a Material
  Adverse Effect.  Except for such of the reprogramming referred
  to in the preceding sentence as may be necessary, the computer
  and management systems of Borrower and its Restricted
  Subsidiaries are and, with ordinary course upgrading and
  maintenance, will continue for the term of this Agreement to be,
  sufficient to permit Borrower and its Restricted Subsidiaries to
  conduct their business without Material Adverse Effect.

       provided that the proceeds of Indebtedness created by an
       Unrestricted Subsidiary or any other Affiliate secured by
       such Liens are in their entirety contributed or advanced to
       such joint venture; provided, further, that with respect to
       any such Indebtedness neither Borrower or any of its
       Restricted Subsidiaries, nor any of the property or assets
       of Borrower or any of its Restricted Subsidiaries, other
       than proceeds realized from the sale or other disposition
       of such capital stock, partnership or other equity
       interests shall, directly or indirectly, be liable for or
       secure in any manner whatsoever the payment thereof;

       so long as such Liens were not incurred, extended or
       renewed in contemplation of such acquisition or purchase;
       provided that (i) the Lien shall attach solely to the
       assets acquired or purchased, (ii) such Lien shall have
       been created or incurred no more than after 180 days of the
       date of acquisition or purchase, (iii) at the time of

       Liens on such assets, whether or not assumed by Borrower or
       any of its Restricted Subsidiaries, shall not exceed an
       amount equal to the lesser of the total purchase price or
       fair market value at the time of acquisition or purchase of
       such assets (as determined in good faith by the Board of
       Directors of Borrower), (iv) if the Indebtedness secured by
       such Liens shall have been incurred by a Restricted
       Subsidiary of Borrower, then and in such event such
       Indebtedness shall be incurred within the limitations
       provided in Section 7.3(e) and Section 8.2(b) hereof, and
       (v) at the time of the creation, issuance, assumption,
       guarantee or incurrence of such Indebtedness and after
       giving effect thereto and to the application of the
       proceeds thereof, no Default, including, without
       limitation, a Default under Section 7.3(e), or Event of
       Default would exist;

       business entity then owning such fixed assets, so long as
       such Liens were not incurred, extended or renewed in
       contemplation of such acquisition or purchase; provided
       that (i) the Lien shall attach solely to the assets
       acquired or purchased, (ii) if the Indebtedness secured by
       such Lien shall have been assumed by a Restricted 
       Subsidiary of Borrower, then and in such event such
       Indebtedness shall be incurred within the limitations
       provided in Section 7.3(e) and Section 8.2(b) hereof, and
       (iii) at the time of the assumption of such Indebtedness
       and after the concurrent giving effect thereto, no Default,

       the terms of this Agreement;
  
            (l)  Liens created or incurred after the Effective
       Date given to secure Indebtedness of Borrower or any of its

       to such Lien in connection with the extension, renewal or
       refunding of the Indebtedness secured thereby; provided
       that (i) such extension, renewal or refunding of the
       Indebtedness to which such Lien relates shall be without
       increase in the principal amount remaining unpaid as of the
       date of such extension, renewal or refunding, (ii) such
       Lien shall attach solely to the same such property and
       (iii) at the time of the extension, renewal or refunding of

  Distribution (other than redemptions, acquisitions or
  retirements of common stock to the extent of net cash proceeds
  received from the substantially concurrent sale or exchange of
  common stock of Borrower) or make or authorize any Restricted
  Investment, unless, immediately after giving effect to the
  proposed Distribution or Restricted Investment, the aggregate
  amount of Distributions declared in the case of dividends or
  made in the case of other Distributions plus the aggregate
  amount of Restricted Investments then held by Borrower and its
  Restricted Subsidiaries (valued immediately after the making of
  such Restricted Investment as provided in the definition
  thereof) during the period from and after the date of this
  Agreement to and including the date of declaration in the case
  of a dividend, the date of payment in the case of any other
  Distribution and the date such Restricted Investment is made,
  would not exceed the sum of:
  
            (i)  $25,000,000; plus
  
            (ii) 50% of Consolidated Net Income (or if such
       Consolidated Net Income is a deficit figure, then minus
       100% of such deficit) for such period determined on a
       cumulative basis commencing on April 1, 1998, to and
       including the date of such declaration, payment or
       commitment; plus
  
            (iii)     an amount equal to the aggregate net cash
       proceeds received by Borrower from the sale on or after the

       Securities convertible into common stock of Borrower or the
       amount that Indebtedness of Borrower owing to a Person
       other than a Subsidiary is reduced by the conversion or
       exchange after the Effective Date of such Indebtedness into
       common stock of Borrower; plus
  
            (iv) to the extent not included in the determination
       of Consolidated Net Income any repayments of or returns in
       cash on any Restricted Investment previously made within
       the limitations of this Section 8.4(a), including the
       reissuance of treasury stock or issuance of new stock of
       Borrower in satisfaction of usual and customary employee
       benefit and other like obligations of Borrower and its
       Subsidiaries that could otherwise be settled in cash; plus
  
            (v)  an amount equal to the aggregate cash paid by
       Borrower for shares of common stock of Borrower to the
       extent additional shares of common stock of Borrower were
       issued by Borrower in connection with the acquisition by
       Borrower of assets within the twelve calendar month period
       immediately preceding the date of determination under this 
       Section.
  
       (b)  For the purposes of making computations under Section
  8.4(a), the amount of any Distribution declared, paid or
  distributed or Restricted Investment made in property or assets
  of Borrower or any of its Restricted Subsidiaries shall be
  deemed to be the book value of such property or assets as of the
  date of declaration in the case of a dividend, the date of
  payment in the case of any other Distribution and the date the
  Restricted Investment is made.  Any corporation which becomes a
  Restricted Subsidiary of Borrower after the date of this
  Agreement shall be deemed to have made, at the time it becomes a
  Restricted Subsidiary of Borrower, all Restricted Investments of
  such corporation existing immediately after it becomes a
  Restricted Subsidiary of Borrower.

       (d)  Borrower will not authorize or make a Distribution on
  its capital stock and neither Borrower nor any of its Restricted
  Subsidiaries will make any Restricted Investment if after giving
  effect to the proposed Distribution or Restricted Investment a
  Default or an Event of Default would exist.

       Restricted Subsidiary so long as in (1) any merger or
       consolidation involving Borrower, Borrower shall be the
       surviving or continuing corporation and (2) in any merger

       corporation if (1) Borrower is the surviving corporation in
       connection with such consolidation or merger and (2) at the

            Borrower if the fair market value of the assets
            exceeds $2,500,000 or (ii) otherwise a Responsible

            all sales or other dispositions not so applied exceed
            $5,000,000 in the aggregate.
  
       Computations pursuant to this Section 8.5(b) shall include

  special, time or demand, provisional or final (but excluding the
  funds held in accounts clearly designated as escrow or trust
  accounts held by Borrower for the benefit of Persons which are
  not Affiliates of Borrower), whether or not such setoff results
  in any loss of interest or other penalty, and including without
  limitation all certificates of deposit, at any time held, and
  any other funds or Property at any time held, and other
  Indebtedness at any time owing by such Lender to or for the
  credit or the account of Borrower against any and all of the
  Obligations irrespective of whether or not such Lender or Agent
  will have made any demand under this Agreement, the Notes or any
  other Loan Document.  Each Lender agrees to promptly notify
  Borrower and Agent after any such setoff and application,
  provided that the failure to give such notice will not affect
  the validity of such setoff and application.  The rights of
  Agent and the Lenders under this Section are in addition to
  other rights and remedies (including without limitation other
  rights of setoff) which Agent or the Lenders may have.  This
  Section is subject to the terms and provisions of Sections 4.5
  and 11.7 hereof.
  
   9.3 Remedies Cumulative.  No remedy, right or power conferred
  upon Agent or any Lender is intended to be exclusive of any
  other remedy, right or power given hereunder or now or hereafter
  existing at law, in equity, or otherwise, and all such remedies,
  rights and powers shall be cumulative.
  
  10.  Agent.
  
   10.1 Appointment, Powers and Immunities.  Each Lender hereby
  irrevocably appoints and authorizes Agent to act as its agent
  hereunder and under the other Loan Documents with such powers as
  are specifically delegated to Agent by the terms hereof and
  thereof, together with such other powers as are reasonably
  incidental thereto.  Any Loan Documents executed in favor of
  Agent shall be held by Agent for the ratable benefit of the
  Lenders. Agent ("Agent" as used in this Section 10 shall include
  reference to its Affiliates and its own and its Affiliates'
  respective officers, shareholders, directors, employees and
  agents) (a) shall not have any duties or responsibilities except
  those expressly set forth in this Agreement and the other Loan
  Documents, and shall not by reason of this Agreement or any
  other Loan Document be a trustee or fiduciary for any Lender;
  (b) shall not be responsible to any Lender for any recitals,
  statements, representations or warranties contained in this
  Agreement or any other Loan Document, or in any certificate or
  other document referred to or provided for in, or received by
  any of them under, this Agreement or any other Loan Document, or
  for the value, validity, effectiveness, genuineness,
  enforceability, execution, filing, registration, collectibility,
  recording, perfection, existence or sufficiency of this
  Agreement or any other Loan Document or any other document
  referred to or provided for herein or therein or any Property
  covered thereby or for any failure by Borrower or any other
  Person to perform any of its obligations hereunder or
  thereunder, and shall not have any duty to inquire into or pass
  upon any of the foregoing matters; (c) shall not be required to
  initiate or conduct any litigation or collection proceedings
  hereunder or under any other Loan Document except to the extent
  requested by the Majority Lenders; (d) shall not be responsible
  for any mistake of law or fact or any action taken or omitted to
  be taken by it hereunder or under any other Loan Document or any
  other document or instrument referred to or provided for herein
  or therein or in connection herewith or therewith, INCLUDING,
  WITHOUT LIMITATION, PURSUANT TO ITS OWN NEGLIGENCE, except for
  its own gross negligence or willful misconduct; (e) shall not be
  bound by or obliged to recognize any agreement among or between
  Borrower and any Lender to which Agent is not a party,
  regardless of whether Agent has knowledge of the existence of
  any such agreement or the terms and provisions thereof; (f)
  shall not be charged with notice or knowledge of any fact or
  information not herein set out or provided to Agent in
  accordance with the terms of this Agreement or any other Loan
  Document; (g) shall not be responsible for any delay, error,
  omission or default of any mail, telegraph, cable or wireless
  agency or operator, and (h) shall not be responsible for the
  acts or edicts of any Governmental Authority.  Agent may employ
  agents and attorneys-in-fact and shall not be responsible for
  the negligence or misconduct of any such agents or
  attorneys-in-fact selected by it with reasonable care.
  
   10.2 Reliance.  Agent shall be entitled to rely upon any
  certification, notice or other communication (including any
  thereof by telephone, telegram or cable) believed by it to be
  genuine and correct and to have been signed or sent by or on
  behalf of the proper Person or Persons, and upon advice and
  statements of legal counsel (which may be counsel for Borrower),
  independent accountants and other experts selected by Agent.  
  Agent shall not be required in any way to determine the identity
  or authority of any Person delivering or executing the same.  As
  to any matters not expressly provided for by this Agreement or
  any other Loan Document, Agent shall in all cases be fully
  protected in acting, or in refraining from acting, hereunder and
  thereunder in accordance with instructions of the Majority
  Lenders, and any action taken or failure to act pursuant thereto
  shall be binding on all of the Lenders.  If any order, writ,
  judgment or decree shall be made or entered by any court
  affecting the rights, duties and obligations of Agent under this
  Agreement or any other Loan Document, then and in any of such
  events Agent is authorized, in its sole discretion, to rely upon
  and comply with such order, writ, judgment or decree which it is
  advised by legal counsel of its own choosing is binding upon it
  under the terms of this Agreement, the relevant Loan Document or
  otherwise; and if Agent complies with any such order, writ,
  judgment or decree, then it shall not be liable to any Lender or
  to any other Person by reason of such compliance even though
  such order, writ, judgment or decree may be subsequently
  reversed, modified, annulled, set aside or vacated.
  
   10.3 Defaults.   Agent shall not be deemed to have knowledge of
  the occurrence of a Default or Event of Default (other than the
  non-payment of principal of or interest on Loans) unless Agent
  has received notice from a Lender or Borrower specifying such
  Default or Event of Default and stating that such notice is a
  "Notice of Default."  In the event that Agent receives such a
  Notice of Default, Agent shall give prompt notice thereof to the
  Lenders (and shall give each Lender prompt notice of each such
  non-payment).  Agent shall (subject to Section 10.7 hereof) take
  such action with respect to such Notice of Default as shall be
  directed by the Majority Lenders and within its rights under the
  Loan Documents and at law or in equity, provided that, unless
  and until Agent shall have received such directions, Agent may
  (but shall not be obligated to) take such action, or refrain
  from taking such action, permitted hereby with respect to such
  Notice of Default as it shall deem advisable in the best
  interests of the Lenders and within its rights under the Loan
  Documents, at law or in equity.
  
   10.4 Material Written Notices.  In the event that Agent
  receives any written notice of a material nature from Borrower
  under the Loan Documents, Agent shall promptly inform each of
  the Lenders thereof.
  
   10.5 Rights as a Lender.  With respect to its Commitments and
  the Loans made by it, Chase Texas in its capacity as a Lender
  hereunder shall have the same rights and powers hereunder as any
  other Lender and may exercise the same as though it were not
  acting in its agency capacity, and the term "Lender" or
  "Lenders" shall, unless the context otherwise indicates, include
  Agent in its individual capacity.  Agent may (without having to
  account therefor to any Lender) accept deposits from, lend money
  to and generally engage in any kind of banking, trust, letter of
  credit, agency or other business with Borrower (and any of its
  Affiliates) as if it were not acting as Agent; and Agent may
  accept fees and other consideration from Borrower (in addition
  to the fees heretofore agreed to between Borrower and Agent) for
  services in connection with this Agreement or otherwise without
  having to account for the same to the Lenders.
  
   10.6 Indemnification.  The Lenders agree to indemnify Agent (to
  the extent not reimbursed under Section 11.3 or Section 11.4
  hereof, but without limiting the obligations of Borrower under
  said Sections 11.3 and 11.4), ratably in accordance with the
  Lenders' respective Commitments (or, after termination of the
  Commitments, ratably in accordance with the Loans held by them,
  respectively), for any and all liabilities, obligations, losses,
  damages, penalties, actions, judgments, suits, costs, expenses
  or disbursements of any kind and nature whatsoever, REGARDLESS
  OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE OF ANY
  INDEMNIFIED PARTIES, which may be imposed on, incurred by or
  asserted against Agent in any way relating to or arising out of
  this Agreement or any other Loan Document or any other documents
  contemplated by or referred to herein or therein or the
  transactions contemplated hereby or thereby (including, without
  limitation, the costs and expenses which Borrower is obligated
  to pay under Sections 11.3 and 11.4 hereof, interest, penalties,
  attorneys' fees and amounts paid in settlement, but excluding,
  unless a Default has occurred and is continuing, normal
  administrative costs and expenses incident to the performance of
  its agency duties hereunder) or the enforcement of any of the
  terms hereof or thereof or of any such other documents; provided
  that no Lender shall be liable for any of the foregoing to the
  extent they arise from the gross negligence or willful
  misconduct of the party to be indemnified.  The obligations of
  the Lenders under this Section 10.6 shall survive the
  termination of this Agreement and the repayment of the Obligations.
  
   10.7 Non-Reliance on Agent and Other Lenders.  Each Lender
  agrees that it has received current financial information with
  respect to Borrower that it has, independently and without
  reliance on Agent or any other Lender and based on such
  documents and information as it has deemed appropriate, made its
  own credit analysis of Borrower and decision to enter into this
  Agreement and that it will, independently and without reliance
  upon Agent or any other Lender, and based on such documents and
  information as it shall deem appropriate at the time, continue
  to make its own analysis and decisions in taking or not taking
  action under this Agreement or any of the other Loan Documents. 
  Agent shall not be required to keep itself informed as to the
  performance or observance by Borrower of this Agreement or any
  of the other Loan Documents or any other document referred to or
  provided for herein or therein or to inspect the Properties or
  books of any Person.  Except for notices, reports and other
  documents and information expressly required to be furnished to
  the Lenders by Agent hereunder or under the  other Loan
  Documents, Agent shall not have any duty or responsibility to
  provide any Lender with any credit or other information
  concerning the affairs, financial condition or business of any
  Person which may come into the possession of Agent.
  
   10.8 Failure to Act.  Except for action expressly required of
  Agent hereunder or  under the other Loan Documents, Agent shall
  in all cases be fully justified in failing or refusing to act
  hereunder and thereunder unless it shall receive further
  assurances to its satisfaction by the Lenders of their
  indemnification obligations under Section 10.6 hereof against
  any and all liability and expense which may be incurred by it by
  reason of taking or continuing to take any such action.
  
   10.9 Resignation or Removal of Agent.  Subject to the
  appointment and acceptance of a successor Agent as provided
  below, Agent may resign at any time by giving notice thereof to
  the Lenders and Borrower, and Agent may be removed at any time
  with or without cause by the Majority Lenders; provided, that
  Agent shall continue as Agent until such time as any successor
  shall have accepted appointment as Agent hereunder.  Upon any
  such resignation or removal, (i) the Majority Lenders with the
  consent of Borrower unless an Event of Default has occurred and
  is continuing shall have the right to appoint a successor Agent
  so long as such successor Agent is also a Lender at the time of
  such appointment and (ii) the Majority Lenders shall have the
  right to appoint a successor Agent that is not a Lender at the
  time of such appointment so long as Borrower consents to such
  appointment (which consent shall not be unreasonably withheld). 
  If no successor Agent shall have been so appointed by the
  Majority Lenders and accepted such appointment within 30 days
  after the retiring Agent's giving of notice of resignation or
  the Majority Lenders' removal of the retiring Agent, then the
  retiring Agent may, on behalf of the Lenders, appoint a
  successor Agent.  Any successor Agent shall be a bank which has
  an office in the United States and a combined capital and
  surplus of at least $250,000,000.  Upon the acceptance of any
  appointment as Agent hereunder by a successor Agent, such
  successor Agent shall thereupon succeed to and become vested
  with all the rights, powers, privileges and duties of the
  retiring Agent and the retiring Agent shall be discharged from
  its duties and obligations hereunder and under any other Loan
  Documents.  Such successor Agent shall promptly specify by
  notice to Borrower its Principal Office referred to in Section
  3.1 and Section 4 hereof.  After any retiring Agent's
  resignation or removal hereunder as Agent, the provisions of
  this Section 10 shall continue in effect for its benefit in
  respect of any actions taken or omitted to be taken by it while
  it was acting as Agent.
  
   10.10 No Partnership.  Neither the execution and
  delivery of this Agreement nor any of the other Loan Documents
  nor any interest the Lenders, Agent or any of them may now or
  hereafter have in all or any part of the Obligations shall
  create or be construed as creating a partnership, joint venture
  or other joint enterprise between the Lenders or among the
  Lenders and Agent.  The relationship between the Lenders, on the
  one hand, and Agent, on the other, is and shall be that of
  principals and agent only, and nothing in this Agreement or any
  of the other Loan Documents shall be construed to constitute
  Agent as trustee or other fiduciary for any Lender or to impose
  on Agent any duty, responsibility or obligation other than those
  expressly provided for herein and therein.
  
   10.11 Authority of Agent.  Each Lender acknowledges
  that the rights and responsibilities of Agent under this
  Agreement and the Loan Documents with respect to any action
  taken by Agent or the exercise or non-exercise by Agent of any
  option, right, request, judgment or other right or remedy
  provided for herein or resulting or arising out of this
  Agreement and/or the other Loan Documents shall, as between
  Agent and the Lenders, be governed by this Agreement and by such
  other agreements with respect thereto as may exist from time to
  time among them, but, as between Agent and Borrower, Agent shall
  be conclusively presumed to be acting as agent for the Lenders
  with full and valid authority so to act or refrain from acting;
  and Borrower shall not be under any obligation, or entitlement,
  to make any inquiry respecting such authority.
  
   10.12 Documentation Agent and Syndication Agent.  Neither
  the Documentation Agent nor the Syndication Agent, in their
  capacities as such, shall have any duties or responsibilities
  under this Agreement.
  
  11.  Miscellaneous.
  
   11.1 Waiver.  No waiver of any Default or Event of Default
  shall be a waiver of any other Default or Event of Default.  No
  failure on the part of Agent or any Lender to exercise and no
  delay in exercising, and no course of dealing with respect to,
  any right, power or privilege under any Loan Document shall
  operate as a waiver thereof, nor shall any single or partial
  exercise of any right, power or privilege thereunder preclude
  any other or further exercise thereof or the exercise of any
  other right, power or privilege.  The remedies provided in the
  Loan Documents are cumulative and not exclusive of any remedies
  provided by law or in equity.
  
   11.2 Notices.  All notices and other communications provided
  for herein (including, without limitation, any modifications of,
  or waivers or consents under, this Agreement) shall be given or
  made by telegraph, telecopy (confirmed by mail), cable or other
  writing and telecopied, telegraphed, cabled, mailed or delivered
  to the intended recipient at the "Address for Notices" specified
  below its name on the signature pages hereof (or provided for in

  Borrower, to Agent, (ii) as to Agent, to Borrower and to each
  Lender, and (iii) as to any Lender, to Borrower and Agent. 
  Except as otherwise provided in this Agreement, all such notices
  or communications shall be deemed to have been duly given when
  (i) transmitted by telecopier or delivered to the telegraph or
  cable office, (ii) personally delivered (iii) one Business Day
  after deposit with a nationally recognized overnight mail or
  delivery service, postage prepaid or (iv) three Business Days'

  Postal Service, postage prepaid, registered or certified mail,
  return receipt requested, in each case given or addressed as 
  aforesaid.
  
   11.3 Expenses, Etc.  Whether or not any Loan is ever made,
  Borrower shall pay or reimburse within 10 Business Days after
  written demand (a) Agent for paying the reasonable fees and
  expenses of legal counsel to Agent, together with the reasonable
  fees and expenses of each local counsel to Agent, in connection
  with the preparation, negotiation, execution and delivery of
  this Agreement (including the exhibits and schedules hereto) and
  the other Loan Documents and the making of the Loans, and any
  modification, supplement or waiver of any of the terms of this
  Agreement or any other Loan Document; (b) Agent for any
  reasonable and customary lien search fees,; (c) Agent for
  reasonable out-of-pocket expenses incurred in connection with
  the preparation, documentation of the Loans or any of the Loan

  respect of this Agreement or any other Loan Document or any
  other document referred to herein or therein, and (e) following
  the occurrence and during the continuation of an Event of
  Default, any Lender or Agent for paying all amounts reasonably
  expended, advanced or incurred by such Lender or Agent to
  satisfy any obligation of Borrower under this Agreement or any
  other Loan Document, to collect the Obligations or to enforce,
  protect, preserve or defend the rights of the Lenders or Agent
  under this Agreement or any other Loan Document, including,
  without limitation, fees and expenses incurred in connection
  with such Lender's or Agent's participation as a member of a
  creditor's committee in a case commenced with Borrower or any of
  its Restricted Subsidiaries as debtor under the Bankruptcy Code
  or other similar law, fees and expenses incurred in connection
  with lifting the automatic stay prescribed in Section 362 of the
  Bankruptcy Code and fees and expenses incurred in connection
  with any action pursuant to Section 1129 of the Bankruptcy Code
  and all other reasonable and customary out-of-pocket expenses
  incurred by such Lender or Agent in connection with such
  matters, together with interest thereon at the Past Due Rate on
  each such amount from the due date until the date of
  reimbursement to such Lender or Agent.
  
   11.4 Indemnification.  Borrower shall indemnify each of Agent,
  the Lenders, and each affiliate thereof and their respective
  directors, officers, employees and agents from, and hold each of
  them harmless against, any and all losses, liabilities, claims
  or damages to which any of them may become subject, REGARDLESS
  OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE OF ANY
  INDEMNIFIED PARTIES, insofar as such losses, liabilities, claims
  or damages arise out of or result from any (i) actual or
  proposed use by Borrower of the proceeds of any extension of
  credit (whether a Loan) by any Lender hereunder; (ii) breach by
  Borrower of this Agreement or any other Loan Document; (iii)
  violation by Borrower or any of its Restricted Subsidiaries of
  any Legal Requirement, or (iv) investigation, litigation or
  other proceeding relating to any of the foregoing, and Borrower
  shall reimburse Agent, each Lender, and each Affiliate thereof
  and their respective directors, officers, employees and agents,
  upon demand for any reasonable and customary expenses (including
  reasonable and customary legal fees) incurred in connection with
  any such investigation or proceeding; provided, however, that
  Borrower shall not have any obligations pursuant to this Section
  with respect to any losses, liabilities, claims, damages or
  expenses incurred by the Person seeking indemnification by
  reason of the gross negligence or willful misconduct of that
  Person or with respect to any disputes between or among any of
  Agent and Lenders.  Nothing in this Section is intended to limit
  the obligations of Borrower under any other provision of this
  Agreement.  In the case of any indemnification hereunder, Agent
  or the respective Lender, as appropriate, shall give written
  notice to Borrower of any such claim or demand being made
  against an indemnified person and Borrower shall have the
  non-exclusive right to join in the defense against any such
  claim or demand, provided that if Borrower provides a defense,
  the indemnified person shall bear its own cost of defense unless
  there is a conflict of interests between Borrower and such
  indemnified person.  No Indemnified Person may settle any claim
  to be indemnified without the consent of Borrower, such consent
  not to be unreasonably withheld or delayed.
  
   11.5 Amendments, Etc.  No amendment or modification of this
  Agreement, the Notes or any other Loan Document shall in any
  event be effective against Borrower unless the same shall be
  agreed or consented to in writing by such Person.  No amendment,
  modification or waiver of any provision of this Agreement, the
  Notes or any other Loan Document, nor any consent to any
  departure by Borrower therefrom, shall in any event be effective
  against the Lenders unless the same shall be agreed or consented
  to in writing by the Majority Lenders, and each such waiver or
  consent shall be effective only in the specific instance and for
  the specific purpose for which given; provided, that no
  amendment, modification, waiver or consent shall, unless in
  writing and signed by each Lender affected thereby, do any of
  the following:  (a) increase any Commitment of any of the
  Lenders (or reinstate any termination or reduction of the
  Commitments) or subject any of the Lenders to any additional
  obligations; (b) reduce the principal of, or interest on, any
  Loan or fee hereunder; (c) postpone or extend the Maturity Date
  or any scheduled date fixed for any payment of principal of, or
  interest on, any Loan, fee or other sum to be paid hereunder or
  waive any Event of Default described in Section 9.1(a) hereof;
  (d) change the percentage of any of the Commitments or of the
  aggregate unpaid principal amount of any of the Loans, or the
  percentage of Lenders, which shall be required for the Lenders
  or any of them to take any action under this Agreement, or (e)
  change any provision contained in Sections 7.9, 11.3 or 11.4
  hereof or this Section 11.5.  Notwithstanding anything in this
  Section 11.5 to the contrary, no amendment, modification, waiver
  or consent shall be made with respect to Section 10 without the
  consent of Agent to the extent it affects Agent, as Agent.
  
   11.6 Successors and Assigns.
  
       (a)  This Agreement shall be binding upon and inure to the
  benefit of Borrower, Agent and the Lenders and their respective
  successors and permitted assigns; provided, however, that,
  except as permitted by Section 8.5 hereof, Borrower may not
  assign or transfer any of its rights or obligations hereunder
  without the prior written consent of all of the Lenders, and any
  such assignment or transfer without such consent shall be null
  and void.  Each Lender may sell participations to any Person in
  all or part of any Loan, or all or part of its Notes or
  Commitments, in which event, without limiting the foregoing, the
  provisions of the Loan Documents shall inure to the benefit of
  each purchaser of a participation; provided, however, the pro
  rata treatment of payments, as described in Section 4.2 hereof
  and rights to compensation under Sections 3.3 and 7.9 hereof,
  shall be determined as if such Lender had not sold such
  participation.  Any Lender that sells one or more participations
  to any Person shall not be relieved by virtue of such
  participation from any of its obligations to Borrower under this
  Agreement relating to the Loans.  In the event any Lender shall
  sell any participation, such Lender shall retain the sole right
  and responsibility to enforce the obligations of Borrower
  relating to the Loans, including, without limitation, the right
  to approve any amendment, modification or waiver of any
  provision of this Agreement other than amendments, modifications
  or waivers with respect to (i) any fees payable hereunder to the
  Lenders and (ii) the amount of principal or the rate of interest
  payable on, or the dates fixed for the scheduled repayment of
  principal of, the Loans.
  
       (b)  Each Lender may assign to one or more Lenders or any
  other Person all or a portion of its interests, rights and
  obligations under this Agreement; provided, however, that (i)
  the amount of the Commitment of the assigning Lender subject to
  each such assignment shall in no event be less than $10,000,000;
  (ii) other than in the case of an assignment to another Lender
  (that is, at the time of the assignment, a party hereto) or to
  an Affiliate of such Lender or to a Federal Reserve Bank, Agent
  and, so long as no Event of Default shall have occurred and be
  continuing, Borrower must each give its prior written consent,
  which consents shall not be unreasonably withheld, and (iii) the
  parties to each such assignment shall execute and deliver to
  Agent, for its acceptance an Assignment and Acceptance in
  substantially the form of Exhibit D hereto (each an "Assignment
  and Acceptance") with blanks appropriately completed, together
  with any Note or Notes subject to such assignment and a
  processing and recording fee of $3,000 paid by the assignee (for
  which Borrower will have no liability).  Upon such execution,
  delivery and acceptance, from and after the effective date
  specified in each Assignment and Acceptance, (A) the assignee
  thereunder shall be a party hereto and, to the extent provided
  in such Assignment and Acceptance, have the rights and
  obligations of a Lender hereunder and (B) the Lender thereunder
  shall, to the extent provided in such Assignment and Acceptance,
  be released from its obligations under this Agreement (and, in
  the case of an Assignment and Acceptance covering all or the
  remaining portion of an assigning Lender's rights and
  obligations under this Agreement, such Lender shall cease to be
  a party hereto except in respect of provisions of this Agreement
  which survive payment of the Obligations and termination of the
  Commitments).  Notwithstanding anything contained in this
  Agreement to the contrary, any Lender may at any time assign all
  or any portion of its rights under this Agreement and the Notes
  issued to it as collateral to a Federal Reserve Bank; provided
  that no such assignment shall release such Lender from any of
  its obligations hereunder.
  
   (c) By executing and delivering an Assignment and Acceptance,
  the Lender assignor thereunder and the assignee thereunder
  confirm to and agree with each other and the other parties
  hereto as follows:  (i) other than the representation and
  warranty that it is the legal and beneficial owner of the
  interest being assigned thereby free and clear of any adverse
  claim, such Lender assignor makes no representation or warranty
  and assumes no responsibility with respect to any statements,
  warranties or representations made in or in connection with this
  Agreement or any of the other Loan Documents or the execution,
  legality, validity, enforceability, genuineness, sufficiency or
  value of this Agreement or any of the other Loan Documents or
  any other instrument or document furnished pursuant thereto;
  (ii) such Lender assignor makes no representation or warranty
  and assumes no responsibility with respect to the financial
  condition of Borrower or the performance or observance by
  Borrower of any of its obligations under this Agreement or any
  of the other Loan Documents to which it is a party or any other
  instrument or document furnished pursuant hereto; (iii) such
  assignee confirms that it has received a copy of this Agreement,
  together with copies of the financial statements most recently
  delivered under either Section 6.2 or Section 7.2 hereof and
  such other documents and information as it has deemed
  appropriate to make its own credit analysis and decision to
  enter into such Assignment and Acceptance; (iv) such assignee
  will, independently and without reliance upon Agent, such Lender
  assignor 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 this Agreement and the other Loan Documents; (v) such
  assignee appoints and authorizes Agent to take such action as
  agent on its behalf and to exercise such powers under this
  Agreement and the other Loan Documents as are delegated to Agent
  by the terms hereof, together with such powers as are reasonably
  incidental thereto; and (vi) such assignee agrees that it will
  perform in accordance with their terms all obligations that by
  the terms of this Agreement and the other Loan Documents are
  required to be performed by it as a Lender.
  
   (d) The entries in the records of Agent as to each Assignment
  and Acceptance delivered to it and the names and addresses of
  the Lenders and the Commitments of, and principal amount of the
  Loans owing to, each Lender from time to time shall be
  conclusive, in the absence of manifest error, and Borrower,
  Agent and the Lenders may treat each Person the name of which is
  recorded in the books and records of Agent as a Lender hereunder
  for all purposes of this Agreement and the other Loan Documents.
  
   (e) Upon Agent's receipt of an Assignment and Acceptance
  executed by an assigning Lender and the assignee thereunder,
  together with any Note or Notes subject to such assignment and
  the written consent to such assignment (to the extent consent is
  required), Agent shall, if such Assignment and Acceptance has
  been completed with blanks appropriately filled, (i) accept such
  Assignment and Acceptance, (ii) record the information contained
  therein in its records and (iii) give prompt notice thereof to
  Borrower.  Within five Business Days after receipt of notice,
  Borrower, at its own expense, shall execute and deliver to Agent
  in exchange for the surrendered Note a new Note to the order of
  such assignee in an amount equal to the Commitment assumed by it
  pursuant to such Assignment and Acceptance and, if the assigning
  Lender has retained  a Commitment hereunder, a new Note to the
  order of the assigning Lender in an amount equal to the
  Commitment retained by it hereunder.  Such new Notes shall be in
  an aggregate principal amount equal to the aggregate principal
  amount of such surrendered Notes, shall be dated the effective
  date of such Assignment and Acceptance and shall otherwise be in
  substantially the form of the respective Note.  Thereafter, such
  surrendered Notes shall be marked renewed and substituted and
  the originals thereof delivered to Borrower (with copies to be
  retained by Agent).
  
   (f) Any Lender may, in connection with any assignment or
  participation or proposed assignment or participation pursuant
  to this Section 11.6, disclose to the assignee or participant or
  proposed assignee or participant, any information relating to
  Borrower furnished to such Lender by or on behalf of Borrower;
  provided such Person agrees to maintain the confidentiality of
  such information in accordance with Section 11.16.
  
   11.7 Limitation of Interest.  The parties hereto intend to
  strictly comply with all applicable federal and Texas laws,
  including applicable usury laws (or the usury laws of any
  jurisdiction whose usury laws are deemed to apply to the Notes
  or any other Loan Documents).  Accordingly, the provisions of
  this Section 11.7 shall govern and control over every other
  provision of this Agreement or any other Loan Document which
  conflicts or is inconsistent with this Section, even if such
  provision declares that it controls.  As used in this Section,
  the term "interest" includes the aggregate of all charges, fees,
  benefits or other compensation which constitute interest under
  applicable law, provided that, to the maximum extent permitted
  by applicable law, (a) any non-principal payment shall be
  characterized as an expense or as compensation for something
  other than the use, forbearance or detention of money and not as
  interest, and (b) all interest at any time contracted for,
  reserved, charged or received shall be amortized, prorated,
  allocated and spread, in equal parts during the full term of the
  Obligations.  In no event shall Borrower or any other Person be
  obligated to pay, or Agent or any Lender have any right or
  privilege to reserve, receive or retain, (a) any interest in
  excess of the maximum amount of nonusurious interest permitted
  under the laws of the State of Texas or the applicable laws (if
  any) of the United States or of any other jurisdiction, or (b)
  total interest in excess of the amount which such Person could
  lawfully have contracted for, reserved, received, retained or
  charged had the interest been calculated for the full term of
  the Obligations at the Ceiling Rate.  The daily interest rates
  to be used in calculating interest at the Ceiling Rate shall be
  determined by dividing the applicable Ceiling Rate per annum by
  the number of days in the calendar year for which such
  calculation is being made.  None of the terms and provisions
  contained in this Agreement or in any other Loan Document
  (including, without limitation, Section 9.1 hereof) which
  directly or indirectly relate to interest shall ever be
  construed without reference to this Section 11.7, or be
  construed to create a contract to pay for the use, forbearance
  or detention of money at an interest rate in excess of the
  Ceiling Rate.  If the term of any Obligation is shortened by
  reason of acceleration of maturity as a result of any Default or
  by any other cause, or by reason of any required or permitted
  prepayment, and if for that (or any other) reason Agent or any
  Lender at any time, including but not limited to, the stated
  maturity, is owed or receives (and/or has received) interest in
  excess of interest calculated at the Ceiling Rate, then and in
  any such event all of any such excess interest shall be canceled
  automatically as of the date of such acceleration, prepayment or
  other event which produces the excess, and, if such excess
  interest has been paid to such Person, it shall be credited pro
  tanto against the then-outstanding principal balance of
  Borrower's obligations to such Person, effective as of the date
  or dates when the event occurs which causes it to be excess
  interest, until such excess is exhausted or all of such
  principal has been fully paid and satisfied, whichever occurs
  first, and any remaining balance of such excess shall be
  promptly refunded to its payor.
  
   11.8 Survival.  The obligations of Borrower under Sections 7.9,
  11.3 and 11.4 hereof and all other obligations of Borrower in
  any other Loan Document (to the extent stated therein)  and the
  obligations of the Lenders under Sections 4.1(d), 10.6, 11.7,
  11.13 and 11.16 hereof, shall, notwithstanding anything herein
  to the contrary, survive the repayment of the Loans and the
  termination of the Commitments.
  
   11.9 Captions.  Captions and section headings appearing
  herein are included solely for convenience of reference and are
  not intended to affect the interpretation of any provision of
  this Agreement.
  
   11.10 Counterparts.  This Agreement may be executed in any
  number of counterparts, all of which taken together shall
  constitute one and the same agreement and any of the parties
  hereto may execute this Agreement by signing any such counterpart.
  
   11.11 Governing Law.  THIS AGREEMENT AND (EXCEPT AS
  THEREIN PROVIDED) THE OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY
  AND CONSTRUED IN ACCORDANCE WITH THE APPLICABLE LAWS OF THE
  STATE OF TEXAS AND THE UNITED STATES OF AMERICA FROM TIME TO
  TIME IN EFFECT.
  
   11.12 Severability.  Whenever possible, each provision
  of the Loan Documents shall be interpreted in such manner as to
  be effective and valid under applicable law.  If any provision
  of any Loan Document shall be invalid, illegal or unenforceable
  in any respect under any applicable law, the validity, legality
  and enforceability of the remaining provisions of such Loan
  Document shall not be affected or impaired thereby.
  
   11.13 Tax Forms.  Each Lender which is organized under
  the laws of a jurisdiction outside the United States shall, on
  the day of the initial borrowing from each such Lender hereunder
  and from time to time thereafter if requested by Borrower or
  Agent, provide Agent and Borrower with the forms prescribed by
  the Internal Revenue Service of the United States certifying as
  to such Lender's status for purposes of determining exemption
  from United States withholding taxes with respect to all
  payments to be made to such Lender hereunder or other documents
  satisfactory to such Lender, Borrower and Agent indicating that
  all payments to be made to such Lender hereunder are not subject
  to United States withholding tax or are subject to such tax at a
  rate reduced by an applicable tax treaty.  If a Lender
  determines, as a result of any change in either (i) applicable
  law, regulation or treaty, or in any official application
  thereof or (ii) its circumstances, that it is unable to submit
  any form or certificate that it is obligated to submit pursuant
  to this Section, or that it is required to withdraw or cancel
  any such form or certificate previously submitted, it shall
  promptly notify Borrower and Agent of such fact.  Unless
  Borrower and Agent shall have received such forms or such
  documents indicating that payments hereunder are not subject to
  United States withholding tax or are subject to such tax at a
  rate reduced by an applicable tax treaty, Borrower or Agent
  shall withhold taxes from such payments at the applicable
  statutory rate.  Each Lender agrees to indemnify and hold
  harmless from any United States taxes, penalties, interest and
  other expenses, costs and losses incurred or payable by (i)
  Agent as a result of such Lender's failure to submit any form or
  certificate that it required to provide pursuant to this Section
  or (ii) Borrower or Agent as a result of their reliance on any
  representation, form or certificate which such Lender has
  provided to them pursuant to this Section.
  
   11.14 Conflicts Between This Agreement and the Other Loan
  Documents.  In the event of any conflict between the terms of
  this Agreement and the terms of any of the other Loan Documents,
  the terms of this Agreement shall control.
  
   11.15 Limitation on Charges; Substitute Lenders;
  Non-Discrimination.  Anything in Sections 3.3(c) or 7.9 
  notwithstanding:
  
            (1)  Borrower shall not be required to pay to any
       Lender reimbursement or indemnification with regard to any
       costs or expenses described in such Sections, unless such
       Lender notifies Borrower of such costs or expenses within
       90 days after the date paid or incurred;
  
            (2)  none of the Lenders shall be permitted to pass
       through to Borrower charges and costs under such Sections
       on a discriminatory basis (i.e., which are not also passed
       through by such Lender to other customers of such Lender
       similarly situated where such customer is subject to
       documents providing for such pass through); and
  
            (3)  if any Lender elects to pass through to Borrower
       any material charge or cost under such Sections or elects
       to terminate the availability of LIBOR Borrowings for any
       material period of time, Borrower may, within 60 days after
       the date of such event and so long as no Default shall have
       occurred and be continuing, elect to terminate such Lender
       as a party to this Agreement; provided that, concurrently
       with such termination Borrower shall (i) if Agent and each
       of the other Lenders shall consent, pay that Lender all
       principal, interest and fees and other amounts owed to such
       Lender through such date of termination or (ii) have
       arranged for another financial institution approved by
       Agent (such approval not to be unreasonably withheld or
       delayed) as of such date, to become a substitute Lender for
       all purposes under this Agreement in the manner provided in
       Section 11.6; provided further that, prior to substitution
       for any Lender, Borrower shall have given written notice to
       Agent of such intention and the Lenders shall have the
       option, but no obligation, for a period of 60 days after
       receipt of such notice, to increase their Commitments in
       order to replace the affected Lender in lieu of such 
       substitution.
  
   11.16 Confidentiality.   Each Lender agrees to exercise its
  best efforts to keep any information delivered or made available
  by Borrower which is clearly indicated to be confidential
  information, confidential from anyone other than Persons
  employed or retained by such Lender or any of its Affiliates who
  are or are expected to become engaged in evaluating, approving,
  structuring or administering the Loans; provided that nothing
  herein shall prevent any Lender from disclosing such information
  (a) to any other Lender; (b) pursuant to subpoena or upon the
  order of any court or administrative agency; (c) upon the
  request or demand of any regulatory agency or authority having
  jurisdiction over such Lender; (d) which has been publicly
  disclosed; (e) to the extent reasonably required in connection
  with any litigation to which Agent, any Lender, Borrower or
  their respective Affiliates may be a party; (f) to the extent
  reasonably required in connection with the exercise of any
  remedy hereunder; (g) to such Lender's bank counsel and
  independent auditors; and (h) to any actual or proposed
  participant or assignee of all or part of its rights hereunder
  which has agreed in writing to be bound by the provisions of
  this Section.
