            CREDIT AGREEMENT, dated as of February 8, 1996, amended and restated
as of March 27, 1996 and further amended and restated as of December 19, 1996,
among DIAMOND OFFSHORE DRILLING, INC. (the "Borrower"), a Delaware corporation,
the lending institutions listed from time to time on Annex I hereto (each a
"Bank" and, collectively, the "Banks"), CHRISTIANIA BANK OG KREDITKASSE, NEW
YORK BRANCH, as Co-Arranger and Documentation Agent, THE FUJI BANK, LIMITED, as
Co-Agent and BANKERS TRUST COMPANY, as Co-Arranger and Administrative Agent (the
"Administrative Agent"). Unless otherwise defined herein, all capitalized terms
used herein and defined in Section 10 are used herein as so defined.


                              W I T N E S S E T H :


            WHEREAS, the Borrower, the Co-Arrangers and the Banks are party to a
Credit Agreement, dated as of February 8, 1996 and amended and restated as of
March 27, 1996 (as in effect immediately prior to the Second Restatement
Effective Date the "Existing Credit Agreement"); and

            WHEREAS, the parties hereto wish to amend and restate the Existing
Credit Agreement as herein provided:


            NOW, THEREFORE, the parties hereto agree that the Existing Credit
Agreement shall be and hereby is amended and restated in its entirety as
follows:


            SECTION 1. Amount and Terms of Credit.

            1.01 Commitment. Subject to and upon the terms and conditions herein
set forth, each Bank severally agrees to make a loan or loans (each a "Loan"
and, collectively, the "Loans") under the Facility to the Borrower, which Loans
(i) shall be made at any time and from time to time on and after the Initial
Borrowing Date and prior to the Maturity Date, (ii) except as hereinafter
provided, may, at the option of the Borrower, be incurred and maintained as,
and/or converted into, Base Rate Loans or Eurodollar Loans, provided that all
Loans made as part of the same Borrowing shall, unless otherwise specifically
provided herein, consist of Loans of the same Type, (iii) may be repaid and
reborrowed in accordance with the provisions hereof, (iv) shall not exceed in
the aggregate for all Banks at any time outstanding, the Total Commitment and
(v) shall not exceed for any Bank at any time outstanding that aggregate
principal amount which, when combined with the aggregate outstanding principal
amount of all other Loans of such Bank and with such



                                     -1-


0000DSZS.W51








Bank's Adjusted Percentage of the Letter of Credit Outstandings (exclusive of
Unpaid Drawings which are repaid with the proceeds of, and simultaneously with
the incurrence of, the respective incurrence of Loans) at such time, equals (1)
if such Bank is a Non-Defaulting Bank, the Adjusted Commitment of such Bank at
such time and (2) if such Bank is a Defaulting Bank, the Commitment of such Bank
at such time.

            1.02 Minimum Borrowing Amounts, etc. The aggregate principal amount
of each Borrowing shall not be less than the Minimum Borrowing Amount for the
Loans constituting such Borrowing. More than one Borrowing may be incurred on
any day, provided that at no time shall there be outstanding more than seven
Borrowings of Eurodollar Loans.

            1.03 Notice of Borrowing. Whenever the Borrower desires to incur
Loans under the Facility, it shall give the Administrative Agent at its Notice
Office, prior to 12:00 Noon (New York time), at least three Business Days' prior
written notice (or telephonic notice promptly confirmed in writing) of each
Borrowing of Eurodollar Loans and at least one Business Day's prior written
notice (or telephonic notice promptly confirmed in writing) of each Borrowing of
Base Rate Loans to be made hereunder. Each such notice (each a "Notice of
Borrowing") shall be in the form of Exhibit A and shall be irrevocable and shall
specify (i) the aggregate principal amount of the Loans to be made pursuant to
such Borrowing, (ii) the date of Borrowing (which shall be a Business Day) and
(iii) whether the respective Borrowing shall consist of Base Rate Loans or (to
the extent permitted) Eurodollar Loans and, if Eurodollar Loans, the Interest
Period to be initially applicable thereto. The Administrative Agent shall
promptly give each Bank written notice (or telephonic notice promptly confirmed
in writing) of each proposed Borrowing, of such Bank's proportionate share
thereof and of the other matters covered by the Notice of Borrowing.

            1.04 Disbursement of Funds. (a) No later than 1:00 P.M. (New York
time) on the date specified in each Notice of Borrowing, each Bank will make
available its pro rata share of each Borrowing requested to be made on such date
in the manner provided below. All such amounts shall be made available to the
Administrative Agent in Dollars and immediately available funds at the Payment
Office and the Administrative Agent promptly will make available to the Borrower
by depositing to its account at the Payment Office the aggregate of the amounts
so made available in Dollars and immediately available funds. Unless the
Administrative Agent shall have been notified by any Bank prior to the date of
Borrowing that such Bank does not intend to make available to the Administrative
Agent its portion of the Borrowing or Borrowings to be made on such date, the
Administrative Agent may assume that such Bank has made such amount available to
the Administrative Agent on such date of Borrowing, and the Administrative
Agent, in reliance upon such assumption, may (in its sole discretion and without
any obligation to do so) make available to the Borrower a corresponding amount.
If such corresponding amount is not in fact made available to the Administrative
Agent by such Bank and the Administrative Agent has made



                                     -2-


0000DSZS.W51








available same to the Borrower, the Administrative Agent shall be entitled to
recover such corresponding amount from such Bank. If such Bank does not pay such
corresponding amount forthwith upon the Administrative Agent's demand therefor,
the Administrative Agent shall promptly (and in any event within two Business
Days from the date the Administrative Agent made such funds available to the
Borrower) notify the Borrower, and the Borrower shall (within two Business Days
of receiving such demand) pay such corresponding amount to the Administrative
Agent. The Administrative Agent shall also be entitled to recover on demand from
such Bank or the Borrower, as the case may be, interest on such corresponding
amount in respect of each day from the date such corresponding amount was made
available by the Administrative Agent to the Borrower to the date such
corresponding amount is recovered by the Administrative Agent, at a rate per
annum equal to (x) if paid by such Bank, the overnight Federal Funds Effective
Rate or (y) if paid by the Borrower, the then applicable rate of interest,
calculated in accordance with Section 1.08, for the respective Loans.

            (b) Nothing herein shall be deemed to relieve any Bank from its
obligation to fulfill its commitments hereunder or to prejudice any rights which
the Borrower may have against any Bank as a result of any default by such Bank
hereunder.

            1.05 Notes. (a) The Borrower's obligation to pay the principal of,
and interest on, the Loans made to it by each Bank shall be evidenced by a
promissory note substantially in the form of Exhibit B with blanks appropriately
completed in conformity herewith (each a "Note" and, collectively, the "Notes").

            (b) The Note issued to each Bank shall (i) be executed by the
Borrower, (ii) be payable to the order of such Bank and be dated the Initial
Borrowing Date, (iii) be in a stated principal amount equal to the Commitment of
such Bank on such date and be payable in the principal amount of the Loans
evidenced thereby, (iv) mature on the Maturity Date, (v) bear interest as
provided in the appropriate clause of Section 1.08 in respect of the Base Rate
Loans and Eurodollar Loans, as the case may be, evidenced thereby, (vi) be
subject to mandatory repayment as provided in Section 4.02 and (vii) be entitled
to the benefits of this Agreement and the other Credit Documents.

            (c) Each Bank will note on its internal records the amount of each
Loan made by it and each payment in respect thereof and will, prior to any
transfer of any of its Notes, endorse on the reverse side thereof the
outstanding principal amount of Loans evidenced thereby. Failure to make any
such notation shall not affect the Borrower's obligations in respect of such
Loans.

            1.06 Conversions. The Borrower shall have the option to convert on
any Business Day all or a portion at least equal to the applicable Minimum
Borrowing Amount of the outstanding principal amount of the Loans owing pursuant
to the Facility into a



                                     -3-


0000DSZS.W51








Borrowing or Borrowings pursuant to the Facility of another Type of Loan,
provided that (i) except as otherwise provided in Section 1.10(b), Eurodollar
Loans may be converted into Base Rate Loans only on the last day of an Interest
Period applicable thereto and no partial conversion of a Borrowing of Eurodollar
Loans shall reduce the outstanding principal amount of the Eurodollar Loans made
pursuant to such Borrowing to less than the Minimum Borrowing Amount applicable
thereto, (ii) no Base Rate Loans may be converted into Eurodollar Loans at any
time when a Default or Event of Default is in existence on the date of the
conversion if the Administrative Agent or the Required Banks have determined
that such a conversion would be disadvantageous to the Banks and (iii)
Borrowings of Eurodollar Loans resulting from this Section 1.06 shall be limited
in number as provided in Section 1.02. Each such conversion shall be effected by
the Borrower giving the Administrative Agent at its Notice Office, prior to
12:00 Noon (New York time), at least three Business Days' (or one Business
Days', in the case of a conversion into Base Rate Loans) prior written notice
(or telephonic notice promptly confirmed in writing) (each a "Notice of
Conversion") specifying the Loans to be so converted, the Type of Loans to be
converted into and, if to be converted into a Borrowing of Eurodollar Loans, the
Interest Period to be initially applicable thereto. The Administrative Agent
shall give each Bank prompt notice of any such proposed conversion affecting any
of its Loans.

            1.07 Pro Rata Borrowings. All Loans under this Agreement shall be
made by the Banks pro rata on the basis of their Commitments. It is understood
that no Bank shall be responsible for any default by any other Bank in its
obligation to make Loans hereunder and that each Bank shall be obligated to make
the Loans provided to be made by it hereunder, regardless of the failure of any
other Bank to fulfill its commitments hereunder.

            1.08 Interest. (a) The unpaid principal amount of each Base Rate
Loan shall bear interest from the date of the Borrowing thereof until maturity
(whether by acceleration or otherwise) at a rate per annum which shall at all
times be the Base Rate in effect from time to time.

            (b) The unpaid principal amount of each Eurodollar Loan shall bear
interest from the date of the Borrowing thereof until maturity (whether by
acceleration or otherwise) at a rate per annum which shall at all times be the
Applicable Eurodollar Margin plus the relevant Eurodollar Rate.

            (c) All overdue principal and, to the extent permitted by law,
overdue interest in respect of each Loan and any other overdue amount payable
hereunder shall bear interest at a rate per annum equal to the greater of (x) 2%
per annum in excess of the rate otherwise applicable to Base Rate Loans from
time to time and (y) the rate which is 2% in excess of the rate then borne by
such Loans, in each case with such interest payable on demand, provided that no
Loan shall bear interest after maturity (whether by acceleration



                                     -4-


0000DSZS.W51








or otherwise) at a rate per annum less than 2% plus the rate of interest
applicable thereto at maturity.

            (d) Interest shall accrue from and including the date of any
Borrowing to but excluding the date of any repayment thereof and shall be
payable (i) in respect of each Base Rate Loan, quarterly in arrears on the first
day of each February, May, August and November, (ii) in respect of each
Eurodollar Loan, on the last day of each Interest Period applicable thereto and,
in the case of an Interest Period of six months, on the date occurring three
months after the first day of such Interest Period and (iii) in respect of each
Loan, on any prepayment or conversion (other than the prepayment and conversion
of Base Rate Loans) (on the amount prepaid or converted), at maturity (whether
by acceleration or otherwise) and, after such maturity, on demand.

            (e) All computations of interest hereunder shall be made in
accordance with Section 12.07(b).

            (f) The Administrative Agent, upon determining the interest rate for
any Borrowing of Eurodollar Loans for any Interest Period, shall promptly notify
the Borrower and the Banks thereof.

            1.09 Interest Periods. (a) At the time the Borrower gives a Notice
of Borrowing or Notice of Conversion in respect of the making of, or conversion
into, a Borrowing of Eurodollar Loans (in the case of the initial Interest
Period applicable thereto) or prior to 12:00 Noon (New York time) on the third
Business Day prior to the expiration of an Interest Period applicable to a
Borrowing of Eurodollar Loans, it shall have the right to elect by giving the
Administrative Agent written notice (or telephonic notice promptly confirmed in
writing) of the Interest Period applicable to such Borrowing, which Interest
Period shall, at the option of the Borrower, be a one, two, three or six month
period. Notwithstanding anything to the contrary contained above:

            (i) the initial Interest Period for any Borrowing of Eurodollar
      Loans shall commence on the date of such Borrowing (including the date of
      any conversion from a Borrowing of Base Rate Loans) and each Interest
      Period occurring thereafter in respect of such Borrowing shall commence on
      the day on which the next preceding Interest Period expires;

           (ii) if any Interest Period begins on a day for which there is no
      numerically corresponding day in the calendar month at the end of such
      Interest Period, such Interest Period shall end on the last Business Day
      of such calendar month;

          (iii) if any Interest Period would otherwise expire on a day which is
      not a Business Day, such Interest Period shall expire on the next
      succeeding Business



                                     -5-

      Day, provided that if any Interest Period would otherwise expire on a day
      which is not a Business Day but is a day of the month after which no
      further Business Day occurs in such month, such Interest Period shall
      expire on the next preceding Business Day;

           (iv) no Interest Period shall extend beyond the Maturity Date;

            (v) no Interest Period may be elected at any time when a Default or
      Event of Default is then in existence if the Administrative Agent or the
      Required Banks have determined that such an election at such time would be
      disadvantageous to the Banks; and

           (vi) in the case of any Eurodollar Loan which is (x) incurred on the
      Second Restatement Effective Date and (y) used to repay an Existing
      Eurodollar Loan pursuant to Section 5.15(a), the first Interest Period
      applicable thereto shall begin on the Second Restatement Effective Date
      and end on the date the Interest Period applicable to such Existing
      Eurodollar Loan would have otherwise ended.

            (b) If upon the expiration of any Interest Period, the Borrower has
failed to (or may not) elect a new Interest Period to be applicable to the
respective Borrowing of Eurodollar Loans as provided above, the Borrower shall
be deemed to have elected to convert such Borrowing into a Borrowing of Base
Rate Loans effective as of the expiration date of such current Interest Period.

            1.10 Increased Costs, Illegality, etc. (a) In the event that (x) in
the case of clause (i) below, the Administrative Agent or (y) in the case of
clauses (ii) and (iii) below, any Bank shall have determined (which
determination shall, absent manifest error, be final and conclusive and binding
upon all parties hereto):

            (i) on any date for determining the Eurodollar Rate for any Interest
      Period that, by reason of any changes arising after the date of this
      Agreement affecting the interbank Eurodollar market, adequate and fair
      means do not exist for ascertaining the applicable interest rate on the
      basis provided for in the definition of Eurodollar Rate; or

           (ii) at any time, that such Bank shall incur increased costs or
      reductions in the amounts received or receivable hereunder with respect to
      any Eurodollar Loans (other than any increased cost or reduction in the
      amount received or receivable resulting from the imposition of or a change
      in the rate or basis of taxes or similar charges) because of (x) any
      change since the date of this Agreement in any applicable law,
      governmental rule, regulation, guideline or order (or in the
      interpretation or administration thereof and including the introduction of
      any new law or govern-



                                     -6-


0000DSZS.W51








      mental rule, regulation, guideline or order) (such as, for example, but
      not limited to, a change in official reserve requirements, but, in all
      events, excluding reserves required under Regulation D to the extent
      included in the computation of the Eurodollar Rate) and/or (y) other
      circumstances occurring after the date of this Agreement and affecting the
      interbank Eurodollar market; or

          (iii) at any time, that the making or continuance of any Eurodollar
      Loan has become unlawful by compliance by such Bank in good faith with any
      law, governmental rule, regulation, guideline (or would conflict with any
      such governmental rule, regulation, guideline or order not having the
      force of law but with which such Bank customarily complies even though the
      failure to comply therewith would not be unlawful);

then, and in any such event, such Bank (or the Administrative Agent in the case
of clause (i) above) shall (x) on such date and (y) within ten Business Days of
the date on which such event no longer exists, give notice (by telephone
confirmed in writing) to the Borrower and to the Administrative Agent of such
determination (which notice the Administrative Agent shall promptly transmit to
each of the other Banks). Thereafter (x) in the case of clause (i) above,
Eurodollar Loans shall no longer be available until such time as the
Administrative Agent notifies the Borrower and the Banks that the circumstances
giving rise to such notice by the Administrative Agent no longer exist, and any
Notice of Borrowing or Notice of Conversion given by the Borrower with respect
to Eurodollar Loans which have not yet been incurred shall be deemed rescinded
by the Borrower, (y) in the case of clause (ii) above, the Borrower shall,
subject to Section 1.12(b) (to the extent applicable), pay to such Bank, upon
written demand therefor, such additional amounts (in the form of an increased
rate of, or a different method of calculating, interest or otherwise as such
Bank in its sole discretion shall determine) as shall be required to compensate
such Bank for such increased costs or reductions in amounts receivable hereunder
(a written notice as to the additional amounts owed to such Bank, showing the
basis for the calculation thereof, submitted to the Borrower by such Bank shall,
absent manifest error, be final and conclusive and binding upon all parties
hereto) and (z) in the case of clause (iii) above, the Borrower shall take one
of the actions specified in Section 1.10(b) as promptly as possible and, in any
event, within the time period required by law.

            (b) At any time that any Eurodollar Loan is affected by the
circumstances described in Section 1.10(a)(ii) or (iii), the Borrower may (and
in the case of a Eurodollar Loan affected pursuant to Section 1.10(a)(iii), the
Borrower shall) either (i) if the affected Eurodollar Loan is then being made
pursuant to a Borrowing, cancel said Borrowing by giving the Administrative
Agent telephonic notice (confirmed promptly in writing) thereof on the same date
that the Borrower was notified by a Bank pursuant to Section 1.10(a)(ii) or
(iii), or (ii) if the affected Eurodollar Loan is then outstanding, upon at
least three Business Days' notice to the Administrative Agent, require the
affected Bank to convert each such



                                     -7-


0000DSZS.W51








Eurodollar Loan into a Base Rate Loan, provided that if more than one Bank is
affected at any time, then all affected Banks must be treated the same pursuant
to this Section 1.10(b).

            (c) If any Bank shall have determined that after the date of this
Agreement, the adoption or effectiveness of any applicable law, rule or
regulation regarding capital adequacy, or any change therein, or any change in
the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by such Bank with any request or directive
regarding capital adequacy (whether or not having the force of law but with
which such Bank customarily complies even though the failure to comply therewith
would not be unlawful) of any such authority, central bank or comparable agency,
has or would have the effect of reducing the rate of return on such Bank's
capital or assets as a consequence of its commitments or obligations hereunder
to a level below that which such Bank could have achieved but for such adoption,
effectiveness, change or compliance (taking into consideration such Bank's
policies with respect to capital adequacy), then from time to time, within 15
days after demand by such Bank (with a copy to the Administrative Agent), the
Borrower shall, subject to Section 1.12(b) (to the extent applicable), pay to
such Bank such additional amount or amounts as will compensate such Bank for
such reduction. Each Bank, upon determining in good faith that any additional
amounts will be payable pursuant to this Section 1.10(c), will give prompt
written notice thereof to the Borrower, which notice shall set forth the basis
of the calculation of such additional amounts, although the failure to give any
such notice shall not release or diminish any of the Borrower's obligations to
pay additional amounts pursuant to this Section 1.10(c) upon the subsequent
receipt of such notice.

            1.11 Compensation. The Borrower shall compensate each Bank, upon its
written request (which request shall set forth the basis for requesting such
compensation), for all reasonable losses, expenses and liabilities (including,
without limitation, any loss, expense or liability incurred by reason of the
liquidation or reemployment of deposits or other funds required by such Bank to
fund its Eurodollar Loans but excluding in any event the loss of anticipated
profits) which such Bank may sustain: (i) if for any reason (other than a
default by such Bank or the Administrative Agent) a Borrowing of Eurodollar
Loans does not occur on a date specified therefor in a Notice of Borrowing or
Notice of Conversion (whether or not withdrawn by the Borrower or deemed
withdrawn pursuant to Section 1.10(a)); (ii) if any prepayment, repayment or
conversion of any of its Eurodollar Loans occurs on a date which is not the last
day of an Interest Period applicable thereto, provided that each Bank waives its
right to such compensation in connection with the repayment on the Second
Restatement Effective Date of Existing Eurodollar Loans; (iii) if any prepayment
of any of its Eurodollar Loans is not made on any date specified in a notice of
prepayment given by the Borrower; or (iv) as a consequence of (x) any other
default by the Borrower to repay its Eurodollar Loans when required by the terms
of this Agreement or (y) an election made pursuant to Section 1.10(b).

            1.12 Change of Lending Office; Limitation on Indemnities. (a) Each
Bank agrees that, upon the occurrence of any event giving rise to the operation
of Section 1.10(a)(ii) or (iii), 1.10(c), 2.06 or 4.04 with respect to such
Bank, it will, if requested by the Borrower, use reasonable efforts (subject to
overall policy considerations of such Bank) to designate another lending office
for any Loan, Letters of Credit or Commitments affected by such event, provided
that such designation is made on such terms that such Bank and its lending
office suffer no economic, legal or regulatory disadvantage, with the object of
avoiding the consequence of the event giving rise to the operation of any such
Section. Nothing in this Section 1.12 shall affect or postpone any of the
obligations of the Borrower or the right of any Bank provided in Section 1.10,
2.06 or 4.04.

            (b) Notwithstanding anything in this Agreement to the contrary, to
the extent any notice required by Section 1.10, 2.06 or 4.04 is given by any
Bank more than 180 days after such Bank obtained, or reasonably should have
obtained, knowledge of the occurrence of the event giving rise to the additional
costs of the type described in such Section, such Bank shall not be entitled to
compensation under Section 1.10, 2.06 or 4.04 for any amounts incurred or
accruing prior to the giving of such notice to the Borrower.

            1.13 Replacement of Banks. (x) Upon the occurrence of any event
giving rise to the operation of Section 1.10(a)(ii) or (iii), Section 1.10(c),
Section 2.06 or Section 4.04 with respect to any Bank which results in such Bank
charging to the Borrower increased costs in excess of those being generally
charged by the other Banks or becoming incapable of making Eurodollar Loans, (y)
if a Bank becomes a Defaulting Bank and/or (z) as provided in Section 12.12(b),
in the case of a refusal by a Bank to consent to a proposed change, waiver,
discharge or termination with respect to this Agreement which has been approved
by the Required Banks, the Borrower shall have the right, if no Default or Event
of Default then exists, to replace such Bank (the "Replaced Bank") with one or
more other Eligible Transferee or Transferees reasonably acceptable to the
Administrative Agent, none of which Transferees shall constitute a Defaulting
Bank at the time of such replacement (collectively, the "Replacement Bank"),
provided that (i) at the time of any replacement pursuant to this Section 1.13,
the Replacement Bank shall enter into one or more Assignment and Assumption
Agreements pursuant to Section 12.04(b) (and with all fees payable pursuant to
said Section 12.04(b) to be paid by the Replacement Bank) pursuant to which the
Replacement Bank shall acquire all of the Commitments and outstanding Loans of,
and in each case participations in Letters of Credit by, the Replaced Bank and,
in connection therewith, shall pay to (x) the Replaced Bank in respect thereof
an amount equal to the sum of (A) an amount equal to the principal of, and all
accrued interest on, all outstanding Loans of the Replaced Bank, (B) an amount
equal to all Unpaid Drawings that have been funded by (and not reimbursed to)
such Replaced Bank, together with all then unpaid interest with respect thereto
at such time and (C) an amount equal to all accrued, but theretofore unpaid,
Fees owing to the Replaced Bank pursuant to Section 3.01, and (y) the Letter of
Credit Issuer an amount equal to such Replaced Bank's Percentage of any



                                     -9-


0000DSZS.W51








Unpaid Drawing (which at such time remains an Unpaid Drawing) to the extent such
amount was not theretofore funded by such Replaced Bank, and (ii) all
obligations of the Borrower owing to the Replaced Bank (other than those
specifically described in clause (i) above in respect of which the assignment
purchase price has been, or is concurrently being, paid) shall be paid in full
to such Replaced Bank concurrently with such replacement. Upon the execution of
the respective Assignment and Assumption Agreements, the payment of amounts
referred to in clauses (i) and (ii) above and, if so requested by the
Replacement Bank, delivery to the Replacement Bank of a Note executed by the
Borrower, the Replacement Bank shall become a Bank hereunder and the Replaced
Bank shall cease to constitute a Bank hereunder, except with respect to
indemnification provisions applicable to the Replaced Bank under this Agreement,
which shall survive as to such Replaced Bank.

            SECTION 2.  Letters of Credit.

            2.01 Letters of Credit. (a) Subject to and upon the terms and
conditions herein set forth, the Borrower may request a Letter of Credit Issuer
to issue, at any time and from time to time on and after the Initial Borrowing
Date and prior to the Maturity Date, and subject to and upon the terms and
conditions herein set forth, such Letter of Credit Issuer agrees to issue from
time to time, (x) for the account of the Borrower and for the benefit of any
holder (or any trustee, agent or other similar representative for any such
holders) of L/C Supportable Obligations of the Borrower or any of its
Subsidiaries, an irrevocable standby letter of credit, in a form customarily
used by such Letter of Credit Issuer or in such other form as has been approved
by such Letter of Credit Issuer (each such standby letter of credit, a "Standby
Letter of Credit") in support of such L/C Supportable Obligations and/or (y) for
the account of the Borrower and for the benefit of sellers of goods or materials
to the Borrower or any of its Subsidiaries, an irrevocable sight documentary
letter of credit in a form customarily used by such Letter of Credit Issuer or
in such other form as has been approved by such Letter of Credit Issuer (each
such documentary letter of credit, a "Trade Letter of Credit", and each such
Trade Letter of Credit and each Standby Letter of Credit, a "Letter of Credit")
in support of commercial transactions of the Borrower and its Subsidiaries.

            (b) Notwithstanding the foregoing, (i) no Letter of Credit shall be
issued, the Stated Amount of which, when added to the Letter of Credit
Outstandings (exclusive of Unpaid Drawings which are repaid on the date of, and
prior to the issuance of, the respective Letter of Credit) at such time, would
exceed either (x) $50,000,000 or (y) when added to the aggregate principal
amount of all Loans made by Non-Defaulting Banks then outstanding, the Adjusted
Total Commitment at such time; and (ii) each Letter of Credit shall have an
expiry date occurring not later than one year after such Letter of Credit's date
of issuance although any Letter of Credit may be extendable for successive
periods of up to 12 months, but not beyond the Business Day next preceding the
Maturity Date, on terms acceptable to the respective Letter of Credit Issuer and
in no event shall any Letter of



                                     -10-


0000DSZS.W51








Credit have an expiry date occurring later than the Business Day immediately
preceding the Maturity Date.

            2.02 Minimum Stated Amount. The initial Stated Amount of each Letter
of Credit shall be not less than $50,000 or such lesser amount acceptable to the
respective Letter of Credit Issuer.

            2.03 Letter of Credit Requests; Request for Issuance of Letter of
Credit. (a) Whenever it desires that a Letter of Credit be issued, the Borrower
shall give the Administrative Agent and the respective Letter of Credit Issuer
written notice (including by way of telecopier) in the form of Exhibit C prior
to 1:00 P.M. (New York time) at least three Business Days (or such shorter
period as may be acceptable to such Letter of Credit Issuer) prior to the
proposed date of issuance (which shall be a Business Day) (each a "Letter of
Credit Request"), which Letter of Credit Request shall include any documents
that such Letter of Credit Issuer customarily requires in connection therewith.
The Administrative Agent shall promptly notify each Bank of each Letter of
Credit Request.

            (b) The respective Letter of Credit Issuer shall, on the date of
each issuance of a Letter of Credit by it, give the Administrative Agent, each
Bank and the Borrower written notice of the issuance of such Letter of Credit,
accompanied by a copy to the Administrative Agent of the Letter of Credit or
Letters of Credit issued by it.

            2.04 Agreement to Repay Letter of Credit Payments. (a) The Borrower
hereby agrees to reimburse each Letter of Credit Issuer, by making payment to
the Administrative Agent at the Payment Office, for any payment or disbursement
made by such Letter of Credit Issuer under any Letter of Credit (each such
amount so paid or disbursed until reimbursed, an "Unpaid Drawing") immediately
after, and in any event on the date on which the Borrower is notified by such
Letter of Credit Issuer of such payment or disbursement with interest on the
amount so paid or disbursed by such Letter of Credit Issuer, to the extent not
reimbursed prior to 1:00 P.M. (New York time) on the date of such payment or
disbursement, from and including the date paid or disbursed to but not including
the date such Letter of Credit Issuer is reimbursed therefor at a rate per annum
which shall be the Base Rate as in effect from time to time (plus an additional
2% per annum if not reimbursed by the third Business Day after the date of such
notice of payment or disbursement), such interest also to be payable on demand.

            (b) The Borrower's obligation under this Section 2.04 to reimburse
the respective Letter of Credit Issuer with respect to Unpaid Drawings
(including, in each case, interest thereon) shall be absolute and unconditional
under any and all circumstances and irrespective of any setoff, counterclaim or
defense to payment which the Borrower may have or have had against such Letter
of Credit Issuer, the Administrative Agent or any Bank, including, without
limitation, any defense based upon the failure of any drawing



                                     -11-


0000DSZS.W51








under a Letter of Credit to conform to the terms of the Letter of Credit (other
than the failure of the respective Letter of Credit Issuer to determine that any
documents required to be delivered under such Letter of Credit have been
delivered and that they substantially comply on their face with the requirements
of such Letter of Credit) or any non-application or misapplication by the
beneficiary of the proceeds of such drawing; provided, however, that the
Borrower shall not be obligated to reimburse any Letter of Credit Issuer for any
wrongful payment made by such Letter of Credit Issuer under a Letter of Credit
as a result of acts or omissions constituting willful misconduct or gross
negligence on the part of such Letter of Credit Issuer.

            2.05 Letter of Credit Participations. (a) Immediately upon the
issuance by any Letter of Credit Issuer of any Letter of Credit, such Letter of
Credit Issuer shall be deemed to have sold and transferred to each other Bank,
and each such Bank (each a "Participant") shall be deemed irrevocably and
unconditionally to have purchased and received from such Letter of Credit
Issuer, without recourse or warranty, an undivided interest and participation,
to the extent of such Bank's Adjusted Percentage, in such Letter of Credit, each
substitute letter of credit, each drawing made thereunder and the obligations of
the Borrower under this Agreement with respect thereto (although the Letter of
Credit Fee shall be payable directly to the Administrative Agent for the account
of the Banks as provided in Section 3.01(b) and the Participants shall have no
right to receive any portion of any Facing Fees) and any security therefor or
guaranty pertaining thereto. Upon any change in the Commitments or Adjusted
Percentages of the Banks pursuant to Section 12.04(b) or upon a Bank Default, it
is hereby agreed that, with respect to all outstanding Letters of Credit and
Unpaid Drawings, there shall be an automatic adjustment to the participations
pursuant to this Section 2.05 to reflect the new Adjusted Percentages of the
assigning and assignee Bank or of all Banks, as the case may be.

            (b) In determining whether to pay under any Letter of Credit, the
respective Letter of Credit Issuer shall not have any obligation relative to the
Participants other than to determine that any documents required to be delivered
under such Letter of Credit have been delivered and that they substantially
comply on their face with the requirements of such Letter of Credit. Any action
taken or omitted to be taken by any Letter of Credit Issuer under or in
connection with any Letter of Credit, if taken or omitted in the absence of
gross negligence or willful misconduct, shall not create for such Letter of
Credit Issuer any resulting liability to the Participants.

            (c) In the event that the respective Letter of Credit Issuer makes
any payment under any Letter of Credit and the Borrower shall not have
reimbursed such amount in full to such Letter of Credit Issuer pursuant to
Section 2.04(a), such Letter of Credit Issuer shall promptly notify the
Administrative Agent, and the Administrative Agent shall promptly notify each
Participant of such failure, and each Participant shall promptly and
unconditionally pay to the Administrative Agent for the account of such Letter
of Credit



                                     -12-


0000DSZS.W51








Issuer, the amount of such Participant's Adjusted Percentage of such payment in
Dollars and in same day funds; provided, however, that no Participant shall be
obligated to pay to the Administrative Agent its Adjusted Percentage of such
unreimbursed amount for any wrongful payment made by such Letter of Credit
Issuer under a Letter of Credit as a result of acts or omissions constituting
willful misconduct or gross negligence on the part of such Letter of Credit
Issuer. If the Administrative Agent so notifies any Participant required to fund
an Unpaid Drawing under a Letter of Credit prior to 12:00 Noon (New York time)
on any Business Day, such Participant shall make available to the Administrative
Agent for the account of the respective Letter of Credit Issuer such
Participant's Adjusted Percentage of the amount of such payment on such Business
Day in same day funds. If and to the extent such Participant shall not have so
made its Adjusted Percentage of the amount of such Unpaid Drawing available to
the Administrative Agent for the account of such Letter of Credit Issuer, such
Participant agrees to pay to the Administrative Agent for the account of such
Letter of Credit Issuer, forthwith on demand such amount, together with interest
thereon, for each day from such date until the date such amount is paid to the
Administrative Agent for the account of such Letter of Credit Issuer at the
overnight Federal Funds Effective Rate. The failure of any Participant to make
available to the Administrative Agent for the account of the respective Letter
of Credit Issuer its Adjusted Percentage of any Unpaid Drawing under any Letter
of Credit shall not relieve any other Participant of its obligation hereunder to
make available to the Administrative Agent for the account of such respective
Letter of Credit Issuer its Adjusted Percentage of any payment under any Letter
of Credit on the date required, as specified above, but no Participant shall be
responsible for the failure of any other Participant to make available to the
Administrative Agent for the account of such Letter of Credit Issuer such other
Participant's Adjusted Percentage of any such payment.

            (d) Whenever the respective Letter of Credit Issuer receives a
payment of a reimbursement obligation as to which the Administrative Agent has
received for the account of such Letter of Credit Issuer any payments from the
Participants pursuant to clause (c) above, such Letter of Credit Issuer shall
pay to the Administrative Agent and the Administrative Agent shall promptly pay
to each Participant which has paid its Adjusted Percentage thereof, in Dollars
and in same day funds, an amount equal to such Participant's Adjusted Percentage
of the principal amount thereof and interest thereon accruing at the overnight
Federal Funds Effective Rate after the purchase of the respective
participations.

            (e) The obligations of the Participants to make payments to the
Administrative Agent for the account of the respective Letter of Credit Issuer
with respect to Letters of Credit shall be irrevocable and not subject to
counterclaim, set-off or other defense or any other qualification or exception
whatsoever (provided that no Participant shall be required to make payments
resulting from such Letter of Credit Issuer's gross negligence or willful
misconduct) and shall be made in accordance with the terms and con-



                                     -13-

ditions of this Agreement under all circumstances, including, without
limitation, any of the following circumstances:

            (i) any lack of validity or enforceability of this Agreement or any
      of the other Credit Documents;

           (ii) the existence of any claim, set-off, defense or other right
      which the Borrower may have at any time against a beneficiary named in a
      Letter of Credit, any transferee of any Letter of Credit (or any Person
      for whom any such transferee may be acting), the Administrative Agent, the
      respective Letter of Credit Issuer, any Bank or other Person, whether in
      connection with this Agreement, any Letter of Credit, the transactions
      contemplated herein or any unrelated transactions (including any
      underlying transaction between the Borrower and the beneficiary named in
      any such Letter of Credit);

          (iii) any draft, certificate or other document presented under the
      Letter of Credit proving to be forged, fraudulent, or invalid in any
      respect or any statement therein being untrue or inaccurate in any
      respect;

            (iv) the surrender or impairment of any security for the performance
      or observance of any of the terms of any of the Credit Documents; or

            (v)   the occurrence of any Default or Event of Default.

            2.06 Increased Costs. If at any time after the date of the
Agreement, the adoption or effectiveness of any applicable law, rule or
regulation, or any change therein, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by the respective Letter of Credit Issuer or any Bank with any request or
directive (whether or not having the force of law but with which such Bank
customarily complies even though the failure to comply therewith would not be
unlawful) by any such authority, central bank or comparable agency shall either
(i) impose, modify or make applicable any reserve, deposit, capital adequacy or
similar requirement against Letters of Credit issued by such Letter of Credit
Issuer or such Bank's participation therein, or (ii) shall impose on such Letter
of Credit Issuer or any Bank any other conditions affecting this Agreement, any
Letter of Credit or such Bank's participation therein; and the result of any of
the foregoing is to increase the cost to such Letter of Credit Issuer or such
Bank of issuing, maintaining or participating in any Letter of Credit, or to
reduce the amount of any sum received or receivable by such Letter of Credit
Issuer or such Bank hereunder (other than any increased cost or reduction in the
amount received or receivable resulting from the imposition of or a change in
the rate or basis of taxes or similar charges), then, upon demand to the
Borrower by such Letter of Credit Issuer or such Bank (a copy of which



                                     -14-


0000DSZS.W51








notice shall be sent by such Letter of Credit Issuer or such Bank to the
Administrative Agent), the Borrower shall, subject to Section 1.12(b) (to the
extent applicable), pay to such Letter of Credit Issuer or such Bank such
additional amount or amounts as will compensate such Letter of Credit Issuer or
such Bank for such increased cost or reduction. A certificate submitted to the
Borrower by the respective Letter of Credit Issuer or such Bank, as the case may
be (a copy of which certificate shall be sent by such Letter of Credit Issuer or
such Bank to the Administrative Agent), setting forth the basis for the
determination of such additional amount or amounts necessary to compensate such
Letter of Credit Issuer or such Bank as aforesaid shall be conclusive and
binding on the Borrower absent manifest error, although the failure to deliver
any such certificate shall not release or diminish any of the Borrower's
obligations to pay additional amounts pursuant to this Section 2.06 upon the
subsequent receipt thereof.

            2.07 Indemnities. The Borrower hereby agrees to reimburse and
indemnify the respective Letter of Credit Issuer for and against any and all
liabilities, obligations, losses, damages, penalties, claims, actions,
judgments, suits, costs, expenses or disbursements of whatsoever kind or nature
which may be imposed on, asserted against or incurred by such Letter of Credit
Issuer in performing its respective duties in any way relating to or arising out
of its issuance of Letters of Credit; provided that the Borrower shall not be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from such Letter of Credit Issuer's gross negligence or willful misconduct. To
the extent the respective Letter of Credit Issuer is not indemnified by the
Borrower, the Participants will reimburse and indemnify such Letter of Credit
Issuer, in proportion to their respective "percentages" of the Total Commitment,
for and against any and all liabilities, obligations, losses, damages,
penalties, claims, actions, judgments, suits, costs, expenses or disbursements
of whatsoever kind or nature which may be imposed on, asserted against or
incurred by such Letter of Credit Issuer in performing its respective duties in
any way relating to or arising out of its issuance of Letters of Credit;
provided that no Participants shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from such Letter of Credit Issuer's
gross negligence or willful misconduct.

            SECTION 3.  Fees; Commitments.

            3.01 Fees. (a) The Borrower agrees to pay to the Administrative
Agent a commitment commission ("Commitment Commission") pro rata for the account
of each Non-Defaulting Bank for the period from and including the Second
Restatement Effective Date to, but not including, the date the Total Commitment
has been terminated, which Commitment Commission shall be equal to the
Applicable Commitment Commission Percentage, computed at such rate for each day,
on the daily amount of such Bank's Available Unutilized Commitment. Such
Commitment Commission shall be due and pay-



                                     -15-

able in arrears on the first day of each February, May, August and November and
on the date upon which the Total Commitment is terminated.

            (b) The Borrower agrees to pay to the Administrative Agent for the
account of each Non-Defaulting Bank pro rata on the basis of their respective
Adjusted Percentages, a fee in respect of each Letter of Credit (the "Letter of
Credit Fee") computed at a rate per annum equal to the Applicable Eurodollar
Margin then in effect on the daily Stated Amount of such Letter of Credit.
Accrued Letter of Credit Fees shall be due and payable quarterly in arrears on
the first day of each February, May, August and November of each year and on the
date after the Total Commitment is terminated and no Letters of Credit remain
outstanding.

            (c) The Borrower agrees to pay to the Administrative Agent for the
account of each Letter of Credit Issuer a fee in respect of each Letter of
Credit issued by it (the "Facing Fee") computed at the rate of 1/8 of 1% per
annum on the daily Stated Amount of such Letter of Credit, provided that in no
event shall the annual Facing Fee to any Letter of Credit Issuer be less than
$500. Accrued Facing Fees shall be due and payable quarterly in arrears on the
fifteenth day of each March, June, September and December of each year and on
the date after the Total Commitment is terminated and no Letters of Credit
remain outstanding.

            (d) The Borrower agrees to pay directly to the respective Letter of
Credit Issuer upon each issuance of, payment under, and/or amendment of, a
Letter of Credit issued by it such amount as shall at the time of such issuance,
payment or amendment be the administrative charge which such Letter of Credit
Issuer is customarily charging for issuances of, payments under or amendments
of, letters of credit issued by it.

            (e) The Borrower shall pay to the Administrative Agent (x) on the
Initial Borrowing Date for its own account and/or for distribution to the Banks
such Fees as heretofore agreed in writing by the Borrower and the Administrative
Agent and (y) for its own account such other fees as agreed to in writing
between the Borrower and the Administrative Agent, when and as due.

            (f) All computations of Fees shall be made in accordance with
Section 12.07(b).

            3.02 Voluntary Reduction of Commitments. Upon at least three
Business Days' prior written notice (or telephonic notice confirmed in writing)
to the Administrative Agent at its Notice Office (which notice the
Administrative Agent shall promptly transmit to each of the Banks), the Borrower
shall have the right, without premium or penalty, to terminate or partially
reduce the Total Unutilized Commitment, provided that (w) any such termination
shall apply to proportionately and permanently reduce the Commitment of each



                                     -16-


0000DSZS.W51








Bank, (x) no such reduction shall reduce any Non-Defaulting Bank's Commitment to
an amount that is less than the sum of (A) the outstanding Loans of such Bank
plus (B) such Bank's Adjusted Percentage of Letter of Credit Outstandings and
(y) any partial reduction pursuant to this Section 3.02 shall be in the amount
of at least $500,000 or integral multiples of $100,000 in excess thereof.

            3.03 Mandatory Adjustments of Commitments, etc. (a) The Total

pursuant to this Section 3.03, on the Business Day following the date of receipt
thereof by the Borrower and/or any of its Subsidiaries of the Cash Proceeds from
any Asset Disposition, the Total Commitment shall be permanently reduced by an
amount equal to 50% of the Net Cash Proceeds arising from such Asset
Disposition; provided that (i) to the extent such proceeds do not exceed
$200,000,000 in the aggregate for the period from and including the Second
Restatement Effective Date to and including the date of such Asset Disposition
or (ii) to the extent any proceeds received pursuant to a Recovery Event are
reinvested or committed to be reinvested within six months of such Recovery
Event in replacement assets owned by the Borrower or its Subsidiaries, such
proceeds (in the case of clauses (i) and (ii) above) shall not be required to be
so applied on such date and (in the case of clause (ii) above) shall not apply
to any calculation made pursuant to clause (i) above.

            (c) Each reduction of the Total Commitment pursuant to this Section
3.03 shall apply proportionately to the Commitment of each Bank.

            SECTION 4.  Payments.

            4.01 Voluntary Prepayments. The Borrower shall have the right to
prepay Loans in whole or in part, without premium or penalty, from time to time
on the following terms and conditions: (i) the Borrower shall give the
Administrative Agent at the Payment Office written notice (or telephonic notice
promptly confirmed in writing) of its intent to prepay the Loans, the amount of
such prepayment and (in the case of Eurodollar Loans) the specific Borrowing or
Borrowings pursuant to which made, which notice shall be given by the Borrower
at least one Business Day prior to the date of such prepayment with respect to
Base Rate Loans and two Business Days prior to the date of such prepayment with
respect to Eurodollar Loans, which notice shall promptly be transmitted by the
Administrative Agent to each of the Banks; (ii) each partial prepayment of any
Borrowing shall be in an aggregate principal amount of at least $500,000 and, if
greater in an integral multiple of $100,000, provided that no partial prepayment
of Eurodollar Loans made pursuant to a Borrowing shall reduce the aggregate
principal amount of the Loans outstanding pursuant to such Borrowing to an
amount less than the Minimum Borrowing Amount appli-



                                     -17-


0000DSZS.W51








cable thereto; (iii) Eurodollar Loans pursuant to this Section 4.01 may only be
prepaid on the last day of the Interest Period applicable thereto; and (iv) each
prepayment in respect of any Loans made pursuant to a Borrowing shall be applied
pro rata among the Banks which made such Loans, provided that at the Borrower's
election in connection with any prepayment of Loans pursuant to this Section
4.01, such prepayment shall not be applied to any Loans of a Defaulting Bank.

            4.02  Mandatory Prepayments.

            (A)  Requirements:

            (a) (i) If on any date the sum of the aggregate outstanding
principal amount of Loans made by Non-Defaulting Banks and the Letter of Credit
Outstandings exceeds the Adjusted Total Commitment as then in effect, the
Borrower shall repay on such date the principal of Loans of Non-Defaulting
Banks, in an aggregate amount equal to such excess. If, after giving effect to
the repayment of all outstanding Loans of Non-Defaulting Banks, the aggregate
amount of Letter of Credit Outstandings exceeds the Adjusted Total Commitment
then in effect, the Borrower shall pay to the Administrative Agent an amount in
cash and/or Cash Equivalents equal to such excess (up to the aggregate amount of
the Letter of Credit Outstandings at such time) and the Administrative Agent
shall hold such payment as security for the obligations of the Borrower
hereunder pursuant to a cash collateral agreement to be entered into in form and
substance reasonably satisfactory to the Administrative Agent (which shall
permit certain investments in Cash Equivalents satisfactory to the
Administrative Agent, until the proceeds are applied to the secured
obligations).

            (ii) If on any date the aggregate outstanding principal amount of
the Loans made by a Defaulting Bank exceeds the Commitment of such Defaulting
Bank, the Borrower shall repay the principal of Loans of such Defaulting Bank in
an amount equal to such excess.

            (b) Notwithstanding anything to the contrary contained elsewhere in
this Agreement, all then outstanding Loans shall be repaid in full on the
Maturity Date.

            (c) On the date on which any Change of Control occurs, unless
otherwise agreed by the Required Banks, the outstanding principal amount of the
Loans, if any, shall become due and payable in full.

0000DSZS.W51








            (B)  Application:

            With respect to each prepayment of Loans required by Section 4.02,
the Borrower may designate the Types of Loans which are to be prepaid and the
specific Borrowing or Borrowings under the Facility pursuant to which made,
provided that (i) Eurodollar Loans may only be repaid if no Base Rate Loans of
Non-Defaulting Banks remain outstanding; (ii) if any prepayment of Eurodollar
Loans made pursuant to a single Borrowing shall reduce the outstanding Loans
made pursuant to such Borrowing to an amount less than the Minimum Borrowing
Amount for such Borrowing, such Borrowing shall be immediately converted into
Base Rate Loans; and (iii) each prepayment of any Loans made by Non-Defaulting
Banks pursuant to a Borrowing shall be applied pro rata among the Non-Defaulting
Banks which made such Loans. In the absence of a designation by the Borrower as
described in the preceding sentence, the Administrative Agent shall, subject to
the above, make such designation in its sole discretion with a view, but no
obligation, to minimize breakage costs owing under Section 1.11. Notwithstanding
the foregoing provisions of this Section 4.02(B), if at any time the mandatory
prepayment of Loans pursuant to Section 4.02(A) above would result, after giving
effect to the procedures set forth above, in the Borrower incurring breakage
costs under Section 1.11 as a result of Eurodollar Loans being prepaid other
than on the last day of an Interest Period applicable thereto (the "Affected
Eurodollar Loans"), then the Borrower may in its sole discretion initially
deposit a portion (up to 100%) of the amounts that otherwise would have been
paid in respect of the Affected Eurodollar Loans with the Administrative Agent
(which deposit must be equal in amount to the amount of the Affected Eurodollar
Loans not immediately prepaid) to be held as security for the obligations of the
Borrower hereunder pursuant to a cash collateral agreement to be entered into in
form and substance reasonably satisfactory to the Administrative Agent and shall
provide for investments satisfactory to the Administrative Agent and the
Borrower, with such cash collateral to be directly applied upon the first
occurrence (or occurrences) thereafter of the last day of an Interest Period
applicable to the relevant Loans that are Eurodollar Loans (or such earlier date
or dates as shall be requested by the Borrower), to repay an aggregate principal
amount of such Loans equal to the Affected Eurodollar Loans not initially
prepaid pursuant to this sentence. Notwithstanding anything to the contrary
contained in the immediately preceding sentence, all amounts deposited as cash
collateral pursuant to the immediately preceding sentence shall be held for the
sole benefit of the Banks whose Loans would otherwise have been immediately
prepaid with the amounts deposited and upon the taking of any action by the
Administrative Agent or the Banks pursuant to the remedial provisions of Section
9, any amounts held as cash collateral pursuant to this Section 4.02(B) shall,
subject to the requirements of applicable law, be immediately applied to the
Loans.

            4.03 Method and Place of Payment. Except as otherwise specifically
provided herein, all payments under this Agreement shall be made to the
Administrative Agent for the ratable (based on its pro rata share) account of
the Banks entitled thereto, not later



                                     -19-


0000DSZS.W51








than 1:00 P.M. (New York time) on the date when due and shall be made in
immediately available funds and in lawful money of the United States of America
at the Payment Office, it being understood that written notice by the Borrower
to the Administrative Agent to make a payment from the funds in the Borrower's
account at the Payment Office shall constitute the making of such payment to the
extent of such funds held in such account. Any payments under this Agreement
which are made later than 1:00 P.M. (New York time) shall be deemed to have been
made on the next succeeding Business Day. Whenever any payment to be made
hereunder shall be stated to be due on a day which is not a Business Day, the
due date thereof shall be extended to the next succeeding Business Day and, with
respect to payments of principal, interest shall be payable during such
extension at the applicable rate in effect immediately prior to such extension.

            4.04 Net Payments. (a) All payments made by the Borrower hereunder
or under any Note will be made without setoff, counterclaim or other defense.
Except as provided in Section 4.04(b), all such payments will be made free and
clear of, and without deduction or withholding for, any present or future taxes,
levies, imposts, duties, fees, assessments or other charges of whatever nature
now or hereafter imposed by any jurisdiction or by any political subdivision or
taxing authority thereof or therein with respect to such payments (but
excluding, except as provided in the second succeeding sentence, any tax imposed
on or measured by the net income or net profits of a Bank pursuant to the laws
of the jurisdiction in which it is organized or managed and controlled or the
jurisdiction in which the principal office or applicable lending office of such
Bank is located or any subdivision thereof or therein) and all interest,
penalties or similar liabilities with respect thereto (all such non-excluded
taxes, levies, imposts, duties, fees, assessments or other charges being
referred to collectively as "Taxes"). If any Taxes are so levied or imposed, the
Borrower agrees to pay the full amount of such Taxes, and such additional
amounts, if any, as may be necessary so that every payment of all amounts due
under this Agreement or under any Note, after withholding or deduction for or on
account of any Taxes, will not be less than the amount provided for herein or in
such Note. If any amounts are payable in respect of Taxes pursuant to the
preceding sentence, the Borrower agrees to reimburse each Bank, upon the written
request of such Bank, for taxes imposed on or measured by the net income or net
profits of such Bank pursuant to the laws of the jurisdiction in which the
principal office or applicable lending office of such Bank is located or under
the laws of any political subdivision or taxing authority of any such
jurisdiction in which the principal office or applicable lending office of such
Bank is located and for any withholding of taxes as such Bank shall determine
are payable by, or withheld from, such Bank in respect of such amounts so paid
to or on behalf of such Bank pursuant to the preceding sentence and in respect
of any amounts paid to or on behalf of such Bank pursuant to this sentence. The
Borrower will furnish to the Administrative Agent within 45 days after the date
the payment of any Taxes is due pursuant to applicable law certified copies of
tax receipts evidencing such payment by the Borrower. The Borrower agrees to
indemnify and hold harm-



                                     -20-


0000DSZS.W51








less each Bank, and reimburse such Bank upon its written request, for the amount
of any Taxes so levied or imposed and paid by such Bank.

            (b) Each Bank that is not a United States person (as such term is
defined in Section 7701(a)(30) of the Code) agrees to deliver to the Borrower
and the Administrative Agent on or prior to the date of this Agreement, or in
the case of a Bank that is an assignee or transferee of an interest under this
Agreement pursuant to Section 1.13 or 12.04 (unless the respective Bank was
already a Bank hereunder immediately prior to such assignment or transfer), on
the date of such assignment or transfer to such Bank, (i) two accurate and
complete original signed copies of Internal Revenue Service Form 4224 or 1001
(or successor forms) certifying to such Bank's entitlement to a complete
exemption from United States withholding tax with respect to payments to be made
under this Agreement and under any Note, or (ii) if the Bank is not a "bank"
within the meaning of Section 881(c)(3)(A) of the Code and cannot deliver either
Internal Revenue Service Form 1001 or 4224 pursuant to clause (i) above, (x) a
certificate substantially in the form of Exhibit D (any such certificate, a
"Section 4.04(b)(ii) Certificate") and (y) two accurate and complete original
signed copies of Internal Revenue Service Form W-8 (or successor form)
certifying to such Bank's entitlement to a complete exemption from United States
withholding tax with respect to payments of interest to be made under this
Agreement and under any Note. In addition, each Bank agrees that from time to
time after the date of this Agreement, when a lapse in time or change in
circumstances renders the previous certification obsolete or inaccurate in any
material respect, it will deliver to the Borrower and the Administrative Agent
two new accurate and complete original signed copies of Internal Revenue Service
Form 4224 or 1001, or Form W-8 and a Section 4.04(b)(ii) Certificate, as the
case may be, and such other forms as may be required in order to confirm or
establish the entitlement of such Bank to a continued exemption from or
reduction in United States withholding tax with respect to payments under this
Agreement and any Note, or it shall immediately notify the Borrower and the
Administrative Agent of its inability to deliver any such Form or Certificate.
Notwithstanding anything to the contrary contained in Section 4.04(a), but
subject to Section 12.04(b) and the immediately succeeding sentence, (x) the
Borrower shall be entitled, to the extent it is required to do so by law, to
deduct or withhold income or similar taxes imposed by the United States (or any
political subdivision or taxing authority thereof or therein) from interest,
fees or other amounts payable hereunder for the account of any Bank which is not
a United States person (as such term is defined in Section 7701(a)(30) of the
Code) for U.S. Federal income tax purposes to the extent that such Bank has not
provided to the Borrower U.S. Internal Revenue Service Forms that establish a
complete exemption from such deduction or withholding and (y) the Borrower shall
not be obligated pursuant to Section 4.04(a) hereof to gross-up payments to be
made to a Bank in respect of income or similar taxes imposed by the United
States if (I) such Bank has not provided to the Borrower the Internal Revenue
Service Forms required to be provided to the Borrower pursuant to this Section
4.04(b) or (II) in the case of a payment, other than interest, to a Bank
described in clause (ii) above, to the extent that such Forms do not establish a



                                     -21-


0000DSZS.W51








complete exemption from withholding of such taxes. Notwithstanding anything to
the contrary contained in the preceding sentence or elsewhere in this Section
4.04 and except as set forth in Section 12.04(b), the Borrower agrees to pay
additional amounts and to indemnify each Bank in the manner set forth in Section
4.04(a) (without regard to the identity of the jurisdiction requiring the
deduction or withholding) in respect of any amounts deducted or withheld by it
as described in the immediately preceding sentence as a result of any changes
after the date of this Agreement in any applicable law, treaty, governmental
rule, regulation, guideline or order, or in the interpretation thereof, relating
to the deducting or withholding of income or similar Taxes, provided such Bank
shall provide to the Borrower and the Administrative Agent any reasonably
available applicable IRS tax form (reasonably similar in its simplicity and lack
of detail to IRS Form 1001) necessary or appropriate for the exemption or
reduction in the rate of such U.S. federal withholding tax.

            (c) The provisions of this Section 4.04 shall be subject to Section
1.12(b) (to the extent applicable).

            SECTION 5. Conditions Precedent. The obligation of the Banks to make

expressly relate to an earlier date in which case they shall be true and correct
in all material respects as of such earlier date).

            5.03 Officer's Certificate. On the Initial Borrowing Date, the
Administrative Agent shall have received a certificate dated such date signed by

misleading at



                                     -28-


0000DSZS.W51








such time in light of the circumstances under which such information was
provided. The Projections contained in such materials are based on good faith
estimates and assumptions believed by such Persons to be reasonable at the time
made, it being recognized by the Banks that such Projections as to future events
are not to be viewed as facts and that actual results during the period or
periods covered by any such Projections may differ from the projected results.
There is no fact known to the Borrower which is reasonably likely to have a
Material Adverse Effect, which has not been disclosed herein or in such other
documents, certificates and statements furnished to the Banks for use in
connection with the transactions contemplated hereby.

            6.10 Financial Condition; Financial Statements; Projections. (a) On
and as of the Initial Borrowing Date, on a pro forma basis after giving effect
to all Indebtedness incurred, and to be incurred, by the Borrower and its
Subsidiaries in connection therewith, (x) the sum of the assets, at a fair
valuation, of the Borrower and its Subsidiaries taken as a whole will exceed its
debts, (y) the Borrower and its Subsidiaries taken as a whole will not have
incurred or intended to, or believe that they will, incur debts beyond their
ability to pay such debts as such debts mature and (z) the Borrower and its
Subsidiaries taken as a whole will not have unreasonably small capital with
which to conduct its business.

            (b) (i) The consolidated balance sheet of the Borrower at December
31, 1995 and the related consolidated statements of operations and cash flows of
the Borrower for the fiscal year, as the case may be, ended as of said date,
which have been examined by Deloitte & Touche LLP, independent certified public
accountants, who delivered an unqualified opinion in respect therewith, and (ii)
the consolidated balance sheet of the Borrower as of September 30, 1996, copies
of which have heretofore been furnished to each Bank, present fairly the
financial position of such entities at the dates of said statements and the
results for the period covered thereby in accordance with GAAP, except to the
extent provided in the notes to said financial statements and, in the case of
the September 30, 1996 statements, subject to normal and recurring year-end
audit adjustments. All such financial statements have been prepared in
accordance with generally accepted accounting principles and practices
consistently applied except to the extent provided in the notes to said
financial statements. Except as expressly disclosed in the Borrower's 10-Q dated
as of September 30, 1996, nothing has occurred since December 31, 1995 that has
had or is reasonably likely to have a Material Adverse Effect.

            (c) Except as reflected in the financial statements and the notes
thereto described in Section 6.10(b) or in Annex VIII, there were as of the
Initial Borrowing Date no liabilities or obligations with respect to the
Borrower or any of its Subsidiaries of a nature (whether absolute, accrued,
contingent or otherwise and whether or not due) which, either individually or in
aggregate, would be material to the Borrower and its Subsidiaries taken as a
whole, except as incurred subsequent to December 31, 1995 in the ordinary course
of business consistent with past practices.



                                     -29-


0000DSZS.W51









            (d) On and as of the Initial Borrowing Date, the Projections
previously delivered to the Administrative Agent and the Banks have been
prepared on a basis consistent with the financial statements referred to in
Section 6.10(a) (other than as set forth or presented in such Projections), and
there are no statements or conclusions in any of the Projections which are based
upon or include information known to the Borrower to be misleading in any
material respect or which fail to take into account material information not
otherwise disclosed in writing to the Administrative Agents and the Banks
regarding the matters reported therein. On the Initial Borrowing Date, the
Borrower believed that the Projections were reasonable and attainable.

            6.11 Tax Returns and Payments. Each of the Borrower and each of its
Subsidiaries has filed all federal income tax returns and all other material tax
returns, domestic and foreign, required to be filed by it and has paid all
material taxes and assessments payable by it which have become due, other than
those not yet delinquent and except for those contested in good faith. The
Borrower and each of its Subsidiaries has paid, or has provided adequate
reserves (in the good faith judgment of the management of the Borrower) for the
payment of, all federal, state and foreign income taxes applicable for all prior
fiscal years and for the current fiscal year to the date hereof.

            6.12 Employee Benefit Plans. (a) Neither the Borrower nor any
Subsidiary nor any ERISA Affiliate has ever maintained or contributed to (or had
an obligation to contribute to) any Plan where any current or reasonably
foreseeable liability of the Borrower with respect to such Plan would exceed
$10,000,000. All contributions required to be made with respect to (i) any
employee pension benefit plan (as defined in Section 3(2) of ERISA) maintained
or contributed to by (or to which there is an obligation to contribute of) the
Borrower or a Subsidiary or an ERISA Affiliate and (ii) any Foreign Pension Plan
have been timely made except any such failures to contribute not exceeding
$10,000,000 individually or in the aggregate. The Borrower and its Subsidiaries
may cease contributions to or terminate any employee benefit plan (within the
meaning of Section 3(3) of ERISA) maintained or contributed to by (or to which
there is an obligation to contribute of) any of them without incurring any
liability in excess of $10,000,000 individually or in the aggregate.

            (b) Each Foreign Pension Plan has been maintained in substantial
compliance with its terms and with the requirements of any and all applicable
laws, statutes, rules, regulations and orders and has been maintained, where
required, in good standing with applicable regulatory authorities. Neither the
Borrower nor any of its Subsidiaries has incurred any material obligation in
connection with the termination of or withdrawal from any Foreign Pension Plan.
The present value of the accrued benefit liabilities (whether or not vested)
under each Foreign Pension Plan, determined as of the end of the Borrower's most
recently ended fiscal year on the basis of actuarial assumptions, each of which
is



                                     -30-


0000DSZS.W51








reasonable, did not exceed the current value of the assets of such Foreign
Pension Plan allocable to such benefit liabilities.

            6.13 Subsidiaries. Annex V lists each Subsidiary of the Borrower
(and the direct and indirect ownership interest of the Borrower therein), in
each case existing on the Second Restatement Effective Date.

            6.14 Patents, etc. The Borrower and each of its Subsidiaries has
obtained all material patents, trademarks, service marks, trade names,
copyrights, licenses and other rights, free from burdensome restrictions, that
are necessary for the operation of their businesses taken as a whole as
presently conducted.

            6.15 Pollution and Other Regulations. (a) Each of the Borrower and
its Subsidiaries is in compliance with all applicable Environmental Laws
governing its business for which failure to comply is reasonably likely to have
a Material Adverse Effect, and neither the Borrower nor any of its Subsidiaries
is liable for any material penalties, fines or forfeitures for failure to comply
with any of the foregoing. All licenses, permits, registrations or approvals
required for the business of the Borrower and each of its Subsidiaries, as
conducted as of the Initial Borrowing Date, under any Environmental Law have
been secured and the Borrower and each of its Subsidiaries is in substantial
compliance therewith, except such licenses, permits, registrations or approvals
the failure to secure or to comply therewith is not likely to have a Material
Adverse Effect. Neither the Borrower nor any of its Subsidiaries is in any
respect in noncompliance with, breach of or default under any applicable writ,
order, judgment, injunction, or decree to which the Borrower or such Subsidiary
is a party or which would affect the ability of the Borrower or such Subsidiary
to operate any Real Property, offshore drilling rig or other facility and no
event has occurred and is continuing which, with the passage of time or the
giving of notice or both, would constitute noncompliance, breach of or default
thereunder, except in each such case, such noncompliance, breaches or defaults
as are not likely to, in the aggregate, have a Material Adverse Effect. There
are as of the Initial Borrowing Date no Environmental Claims pending or, to the
best knowledge of the Borrower, threatened, against the Borrower or any of its
Subsidiaries wherein an unfavorable decision, ruling or finding would be
reasonably likely to have a Material Adverse Effect. There are no facts,
circumstances, conditions or occurrences on any Real Property, offshore drilling
rig or other facility owned or operated by the Borrower or any of its
Subsidiaries that is reasonably likely (i) to form the basis of an Environmental
Claim against the Borrower, any of its Subsidiaries or any Real Property,
offshore drilling rig or other facility owned by the Borrower or any of its
Subsidiaries, or (ii) to cause such Real Property, offshore drilling rig or
other facility to be subject to any restrictions on its ownership, occupancy,
use or transferability under any Environmental Law, except in each such case,
such Environmental Claims or restrictions that individually or in the aggregate
are not reasonably likely to have a Material Adverse Effect.

0000DSZS.W51









            (b) Hazardous Materials have not at any time been (i) generated,
used, treated or stored on, or transported to or from, any Real Property,
offshore drilling rig or other facility at any time owned or operated by the
Borrower or any of its Subsidiaries or (ii) released on or from any such Real
Property, offshore drilling rig or other facility, in each case where, to the
best of the Borrower's knowledge, such occurrence or event individually or in
the aggregate is reasonably likely to have a Material Adverse Effect.

            6.16 Properties. (a) The Borrower and each of its Subsidiaries has
title to all material properties owned by them including all property reflected
in the consolidated balance sheet of the Borrower and its Subsidiaries as
referred to in Section 6.10(b), free and clear of all Liens, other than (i) as
referred to in the consolidated balance sheet or in the notes thereto, (ii)
Permitted Liens or (iii) Liens described in Section 5.15(b).

            (b) Annex VI sets forth all the Real Property owned or leased by the
Borrower and each of its Subsidiaries on the Second Restatement Effective Date,
and (i) identifies each such property by its street address and, if a property
located within the United States of America, by a detailed description thereof,
(ii) identifies the current owner (and current record owner, if different) and
whether such property is leased or owned, (iii) provides a summary description
of the use of such property on the Second Restatement Effective Date and (iv) if
such property is leased, states the term of such lease and the current rent
thereunder.

            (c) Annex VII sets forth all the offshore drilling rigs and other
vessels owned or chartered by the Borrower and each of its Subsidiaries on the
Second Restatement Effective Date, and identifies the registered owner, flag,
official or patent number, as the case may be, the home port, class, location
and operating status on the Second Restatement Effective Date, and, if
chartered-in by the Borrower or any of its Subsidiaries, the name and address of
the owner of such chartered-in vessel.

            6.17 Labor Relations. Neither the Borrower nor its Subsidiaries is
engaged in any unfair labor practice that is reasonably likely to have a
Material Adverse Effect. There is (i) no unfair labor practice complaint pending
against the Borrower or any of its Subsidiaries or threatened against any of
them, before the National Labor Relations Board, and no grievance or arbitration
proceeding arising out of or under any collective bargaining agreement is so
pending against the Borrower or any of its Subsidiaries or, to the best of the
Borrower's knowledge, threatened against any of them, (ii) no strike, labor
dispute, slowdown or stoppage pending against the Borrower or any of its
Subsidiaries or, to the best of the Borrower's knowledge, threatened against the
Borrower or any of its Subsidiaries and (iii) no union representation petition
existing with respect to the employees of the Borrower or any of its
Subsidiaries and no union organizing activities are taking place, except with
respect to any matter specified in clause (i), (ii) or (iii) above, either

0000DSZS.W51








individually or in the aggregate, such as is not reasonably likely to have a
Material Adverse Effect.

            6.18 Existing Indebtedness. Annex VII sets forth a true and complete
list of all Indebtedness of the Borrower and each of its Subsidiaries on the
Second Restatement Effective Date and which is to remain outstanding after the
Initial Borrowing Date (excluding the Loans and the Letters of Credit, the
"Existing Indebtedness"), in each case showing the aggregate principal amount
thereof and the name of the respective borrower (or issuer) and any other entity
which directly or indirectly guaranteed such debt.

            6.19 Rig Classification. Each offshore drilling rig (except for such
offshore drilling rigs listed on Annex III) owned or leased by the Borrower and
its Subsidiaries is classified in the highest class available for rigs of its
age and type with the American Bureau of Shipping, Inc. or another
internationally recognized classification society acceptable to the
Administrative Agent, free of any requirements or recommendations, other than
such requirements or recommendations which if not cured by the owner thereof
would not materially diminish such rig's value.

            SECTION 7. Affirmative Covenants. The Borrower covenants and agrees
that on the Initial Borrowing Date and thereafter for so long as this Agreement
is in effect and until the Commitments have terminated, no Letters of Credit or

Fees and all other Obligations incurred hereunder, are paid in full:

            SECTION 11. The Administrative Agent.

            11.01 Appointment. The Banks hereby designate Bankers Trust Company
as Administrative Agent to act as specified herein and in the other Credit
Documents. Each Bank hereby irrevocably authorizes, and each holder of any Note
by the acceptance of such Note shall be deemed irrevocably to authorize, the
Administrative Agent to take such action on its behalf under the provisions of
this Agreement, the other Credit Documents and any other instruments and
agreements referred to herein or therein and to exercise such powers and to
perform such duties hereunder and thereunder as are specifically delegated to or
required of the Administrative Agent by the terms hereof and thereof and such
other powers as are reasonably incidental thereto. The Administrative Agent may
perform any of its duties hereunder by or through its respective officers,
directors, agents, employees or Affiliates.

            11.02 Nature of Duties. The Administrative Agent shall not have any
duties or responsibilities except those expressly set forth in this Agreement
and the other Credit Documents. Neither the Administrative Agent nor any of its
respective officers, directors, agents, employees or Affiliates shall be liable
for any action taken or omitted by it or them hereunder or under any other
Credit Document or in connection herewith or therewith, unless caused by its or
their gross negligence or willful misconduct. The duties of the Administrative
Agent shall be mechanical and administrative in nature; the Administrative Agent
shall not have by reason of this Agreement or any other Credit Document a
fiduciary relationship in respect of any Bank or the holder of any Note; and
nothing in this Agreement or any other Credit Document, expressed or implied, is
intended to or shall be so construed as to impose upon the Administrative Agent
any obligations in respect of this Agreement or any other Credit Document except
as expressly set forth herein or therein.

            11.03 Lack of Reliance on the Administrative Agent. Independently
and without reliance upon the Administrative Agent, each Bank and the holder of
each Note, to the extent it deems appropriate, has made and shall continue to
make (i) its own independent investigation of the financial condition and
affairs of the Borrower and its Subsidiaries in connection with the making and
the continuance of the Loans and issuance and/or participation in Letters of
Credit and the taking or not taking of any action in connection herewith and
(ii) its own appraisal of the creditworthiness of the Borrower and its
Subsidiaries and, except as expressly provided in this Agreement, the
Administrative Agent shall not have any duty or responsibility, either initially
or on a continuing basis, to provide any Bank or the holder of any Note with any
credit or other information with respect thereto, whether coming into its
possession before the making of the Loans or at any time or times thereafter.
The Administrative Agent shall not be responsible to any Bank or the holder



                                     -66-


0000DSZS.W51








of any Note for any recitals, statements, information, representations or
warranties herein or in any document, certificate or other writing delivered in
connection herewith or for the execution, effectiveness, genuineness, validity,
enforceability, perfection, collectibility, priority or sufficiency of this
Agreement or any other Credit Document or the financial condition of the
Borrower and its Subsidiaries or be required to make any inquiry concerning
either the performance or observance of any of the terms, provisions or
conditions of this Agreement or any other Credit Document, or the financial
condition of the Borrower and its Subsidiaries or the existence or possible
existence of any Default or Event of Default.

            11.04 Certain Rights of the Administrative Agent. If the
Administrative Agent shall request instructions from the Required Banks with
respect to any act or action (including failure to act) in connection with this
Agreement or any other Credit Document, the Administrative Agent shall be
entitled to refrain from such act or taking such action unless and until the
Administrative Agent shall have received instructions from the Required Banks;
and the Administrative Agent shall not incur liability to any Person by reason
of so refraining. Without limiting the foregoing, neither any Bank nor the
holder of any Note shall have any right of action whatsoever against the
Administrative Agent as a result of the Administrative Agent acting or
refraining from acting hereunder or under any other Credit Document in
accordance with the instructions of the Required Banks.

            11.05 Reliance. The Administrative Agent shall be entitled to rely,
and shall be fully protected in relying, upon any note, writing, resolution,
notice, statement, certificate, telex, teletype or telecopier message,
cablegram, radiogram, order or other document or telephone message signed, sent
or made by any Person that the Administrative Agent believed to be the proper
Person, and, with respect to all legal matters pertaining to this Agreement and
any other Credit Document and its duties hereunder and thereunder, upon advice
of counsel selected by the Administrative Agent (which may be counsel for the
Borrower).

            11.06 Indemnification. To the extent the Administrative Agent is not
reimbursed and indemnified by the Borrower, the Banks will reimburse and
indemnify the Administrative Agent, in proportion to their respective
"percentages" as used in determining the Required Banks, for and against any and
all liabilities, obligations, losses, damages, penalties, claims, actions,
judgments, costs, expenses or disbursements of whatsoever kind or nature which
may be imposed on, asserted against or incurred by the Administrative Agent in
performing its respective duties hereunder or under any other Credit Document,
in any way relating to or arising out of this Agreement or any other Credit
Document; provided that no Bank shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the Administrative Agent's gross
negligence or willful misconduct.

            11.07 The Administrative Agent in Its Individual Capacity. With
respect to its obligation to make Loans under this Agreement, the Administrative
Agent shall have the rights and powers specified herein for a "Bank" and may
exercise the same rights and powers as though it were not performing the duties
specified herein; and the term "Banks,"



                                     -67-


0000DSZS.W51








"Required Banks," "holders of Notes" or any similar terms shall, unless the
context clearly otherwise indicates, include the Administrative Agent in its
individual capacity. The Administrative Agent may accept deposits from, lend
money to, and generally engage in any kind of banking, trust or other business
with the Borrower or its Subsidiaries or any Affiliate thereof as if it were not
performing the duties specified herein, and may accept fees and other
consideration from the Borrower or any of its Subsidiaries for services in
connection with this Agreement and otherwise without having to account for the
same to the Banks.

            11.08 Holders. The Administrative Agent may deem and treat the payee
of any Note as the owner thereof for all purposes hereof unless and until a
written notice of the assignment, transfer or endorsement thereof, as the case
may be, shall have been filed with the Administrative Agent. Any request,
authority or consent of any Person who, at the time of making such request or
giving such authority or consent, is the holder of any Note shall be conclusive
and binding on any subsequent holder, transferee, assignee or indorsee, as the
case may be, of such Note or of any Note or Notes issued in exchange therefor.

            11.09 Resignation by the Administrative Agent. (a) The
Administrative Agent may resign from the performance of all its functions and
duties hereunder and/or under the other Credit Documents at any time by giving
15 Business Days' prior written notice to the Borrower and the Banks. Such
resignation shall take effect upon the appointment of a successor Administrative
Agent pursuant to clauses (b) and (c) below or as otherwise provided below.

            (b) Upon any such notice of resignation, the Required Banks shall
appoint a successor Administrative Agent hereunder or thereunder who shall be a
commercial bank or trust company reasonably acceptable to the Borrower.

            (c) If a successor Administrative Agent shall not have been so
appointed within such 15 Business Day period, the Administrative Agent, with the
consent of the Borrower, shall then appoint a successor Administrative Agent who
shall serve as Administrative Agent hereunder or thereunder until such time, if
any, as the Required Banks appoint a successor Administrative Agent as provided
above.

            (d) If no successor Administrative Agent has been appointed pursuant
to clause (b) or (c) above by the 20th Business Day after the date such notice
of resignation was given by the Administrative Agent, the Administrative Agent's
resignation shall become effective and the Required Banks shall thereafter
perform all the duties of the Administrative Agent hereunder and/or under any
other Credit Document until such time, if any, as the Required Banks appoint a
successor Administrative Agent as provided above.

            SECTION 12.  Miscellaneous.

            12.01 Payment of Expenses, etc. The Borrower agrees to (and to cause
each other Credit Party, in respect of the Credit Document to which it is a
party, to): (i) whether or not the transactions herein contemplated are
consummated, pay all reasonable out-of-pocket costs and expenses of the
Administrative Agent and the Co-Arrangers in connection with the negotiation,
preparation, execution and delivery of the Credit Documents and the documents
and instruments referred to therein and any amendment, waiver or consent
relating thereto (including, without limitation, the reasonable fees and
disbursements of White & Case) and of the Administrative Agent and, after the
occurrence and during the continuance of an Event of Default, each of the Banks
in connection with the enforcement of the Credit Documents and the documents and
instruments referred to therein (including, without limitation, the actual
reasonable fees and disbursements of counsel for the Administrative Agent and,
after the occurrence and during the continuance of an Event of Default for each
of the Banks); (ii) pay and hold each of the Banks harmless from and against any
and all present and future stamp and other similar taxes with respect to the
foregoing matters and save each of the Banks harmless from and against any and
all liabilities with respect to or resulting from any delay or omission (other
than to the extent attributable to such Bank) to pay such taxes; and (iii)
indemnify each Bank (including in its capacity as the Administrative Agent or a
Letter of Credit Issuer), its officers, directors, employees, representatives
and agents from and hold each of them harmless against any and all losses,
liabilities, claims, damages or expenses incurred by any of them as a result of,
or arising out of, or in any way related to, or by reason of, (a) any
investigation, litigation or other proceeding (whether or not any Bank is a
party thereto) related to the entering into and/or performance of any Credit
Document or the use of the proceeds of any Loans hereunder or the consummation
of any transactions contemplated in any Credit Document, whether initiated by
the Borrower or any other Person, including, without limitation, the actual
reasonable fees and disbursements of counsel incurred in connection with any
such investigation, litigation or other proceeding (but excluding any such
losses, liabilities, claims, damages or expenses to the extent incurred by
reason of the gross negligence or willful misconduct of the Person to be
indemnified) or (b) the actual or alleged presence of Hazardous Materials in the
air, surface water, groundwater, surface or subsurface of any Real Property,
offshore drilling rig, facility or location at any time owned or operated by the
Borrower or any of its Subsidiaries, the generation, storage, transportation or
disposal of Hazardous Materials at any Real Property, offshore drilling rig,
facility or location at any time owned or operated by the Borrower or any of its
Subsidiaries, the non-compliance of any Real Property, offshore drilling rig,
facility or location at any time owned or operated by the Borrower or any of its
Subsidiaries with federal, state and local laws, regulations, and ordinances
(including applicable permits thereunder) applicable to any such Real Property,
offshore drilling rig, facility or location, or any Environmental Claim asserted
against the Borrower, any of its Subsidiaries, or any Real Property, offshore
drilling rig, facility or location at any time owned or operated by the Borrower
or any of its Subsidiaries, including, in each case, without limitation, the
actual reasonable fees and disbursements of counsel and other consultants
incurred in connection with any such investigation, litigation or other
proceeding (but excluding any losses, liabilities, claims,



                                     -69-


0000DSZS.W51








damages or expenses to the extent incurred by reason of the gross negligence or
willful misconduct of the Person to be indemnified). To the extent that the
undertaking to indemnify, pay or hold harmless the Administrative Agent or any
Bank set forth in the preceding sentence may be unenforceable because it is
violative of any law or public policy, the Borrowers shall make the maximum
contribution to the payment and satisfaction of each of the indemnified
liabilities which is permissible under applicable law.

            12.02 Right of Setoff. In addition to any rights now or hereafter
granted under applicable law or otherwise, and not by way of limitation of any
such rights, if an Event of Default then exists, each Bank is hereby authorized
at any time or from time to time, without presentment, demand, protest or other
notice of any kind to the Borrower or to any other Person, any such notice being
hereby expressly waived, to set off and to appropriate and apply any and all
deposits (general or special) and any other Indebtedness at any time held or
owing by such Bank (including without limitation by branches and agencies of
such Bank wherever located) to or for the credit or the account of the Borrower
against and on account of the Obligations and liabilities of the Borrower to
such Bank under this Agreement or under any of the other Credit Documents,
including, without limitation, all interests in Obligations of the Borrower
purchased by such Bank pursuant to Section 12.06(b), and all other claims of any
nature or description arising out of or connected with this Agreement or any
other Credit Document, irrespective of whether or not such Bank shall have made
any demand hereunder and although said Obligations, liabilities or claims, or
any of them, shall be contingent or unmatured.

            12.03 Notices. (a) Except as otherwise expressly provided herein,
all notices and other communications provided for hereunder shall be in writing
(including telex or telecopier communication) and mailed, telexed, telecopied or
delivered, if to the Borrower or its Subsidiaries, at the address specified
opposite its signature below or in the other relevant Credit Documents, as the
case may be; if to any Bank, at its address specified for such Bank on Annex II;
or, at such other address as shall be designated by any party in a written
notice to the other parties hereto. All such notices and communications shall be
effective when received and, in the case of notice by telecopier, after
confirmation of such receipt has been given by the recipient, excluding by way
of automatic receipt produced by telecopier.

            (b) Without in any way limiting the obligation of the Borrower to
confirm in writing any telephonic notice permitted to be given hereunder, the
Administrative Agent or any Letter of Credit Issuer, as the case may be, may
prior to receipt of written confirmation act without liability upon the basis of
such telephonic notice, believed by the Administrative Agent or such Letter of
Credit Issuer in good faith to be from an Authorized Officer of the Borrower. In
each such case, the Borrower hereby waives the right to dispute the
Administrative Agent's or such Letter of Credit Issuer's record of the terms of
such telephonic notice.

            12.04 Benefit of Agreement. (a) This Agreement shall be binding upon
and inure to the benefit of and be enforceable by the respective successors and
assigns of



                                     -70-


0000DSZS.W51








the parties hereto, provided that the Borrower may not assign or transfer any of
its rights or obligations hereunder without the prior written consent of the
Banks. Each Bank may at any time grant participations in any of its rights
hereunder or under any of the Notes to another financial institution, provided
that in the case of any such participation, the participant shall not have any
rights under this Agreement or any of the other Credit Documents (the
participant's rights against such Bank in respect of such participation to be
those set forth in the agreement executed by such Bank in favor of the
participant relating thereto) and all amounts payable by the Borrower hereunder
shall be determined as if such Bank had not sold such participation, except that
the participant shall be entitled to the benefits of Sections 1.10 and 4.04 of
this Agreement to the extent that such Bank would be entitled to such benefits
if the participation had not been entered into or sold, and, provided further,
that no Bank shall transfer, grant or assign any participation under which the
participant shall have rights to approve any amendment to or waiver of this
Agreement or any other Credit Document except to the extent such amendment or
waiver would (i) extend the final scheduled maturity of any Loan or Note in
which such participant is participating or reduce the rate or extend the time of
payment of interest or Fees thereon (except in connection with a waiver of the
applicability of any post-default increase in interest rates), or reduce the
principal amount thereof, or increase such participant's participating interest
in any Commitment over the amount thereof then in effect (it being understood
that a waiver of any Default or Event of Default or of a mandatory reduction in
the Total Commitment, or a mandatory prepayment, shall not constitute a change
in the terms of any Commitment) or (ii) consent to the assignment or transfer by
the Borrower of any of its rights and obligations under this Agreement.

            (b) Notwithstanding the foregoing, (x) any Bank may assign all or a
portion of its outstanding Commitment and its rights and obligations hereunder
to its Affiliate or to another Bank, and (y) with the consent of the
Administrative Agent, each Letter of Credit Issuer and the Borrower (which
consent shall not be unreasonably withheld), any Bank may assign all or a
portion of its outstanding Commitment and its rights and obligations hereunder
to one or more Eligible Transferees. No assignment pursuant to the immediately
preceding sentence shall to the extent such assignment represents an assignment
to an institution other than one or more Banks hereunder, be in an aggregate
amount less than $5,000,000 unless the entire Commitment of the assigning Bank
is so assigned. If any Bank so sells or assigns all or a part of its rights
hereunder or under the Notes, any reference in this Agreement or the Notes to
such assigning Bank shall thereafter refer to such Bank and to the respective
assignee to the extent of their respective interests and the respective assignee
shall have, to the extent of such assignment (unless otherwise provided
therein), the same rights and benefits as it would if it were such assigning
Bank. Each assignment pursuant to this Section 12.04(b) shall be effected by the
assigning Bank and the assignee Bank executing an Assignment and Assumption
Agreement. In the event of any such assignment (x) to a commercial bank or other
financial institution not previously a Bank hereunder, either the assigning or
the assignee Bank shall pay to the Administrative Agent a nonrefundable
assignment fee of $3,500 and (y) to a Bank, either the assigning or assignee
Bank shall pay to Administrative Agent a nonrefundable assignment fee of $1,500,
and at the time of any assignment pursuant to this Section 12.04(b), (i) Annex I
shall be



                                     -71-


0000DSZS.W51








deemed to be amended to reflect the Commitment of the respective assignee (which
shall result in a direct reduction to the Commitment of the assigning Bank) and
of the other Banks, and (ii) if any such assignment occurs after the Initial
Borrowing Date, if requested by the assigning Bank and the assignee Bank, the
Borrower will issue new Notes to the respective assignee and to the assigning
Bank in conformity with the requirements of Section 1.05. Each Bank and the
Borrower agree to execute such documents (including, without limitation,
amendments to this Agreement and the other Credit Documents) as shall be
necessary to effect the foregoing. Nothing in this clause (b) shall prevent or
prohibit any Bank from pledging its Notes or Loans to a Federal Reserve Bank in
support of borrowings made by such Bank from such Federal Reserve Bank.

            (c) Notwithstanding any other provisions of this Section 12.04, no
transfer or assignment of the interests or obligations of any Bank hereunder or
any grant of participation therein shall be permitted if such transfer,
assignment or grant would require the Borrower to file a registration statement
with the SEC or to qualify the Loans under the "Blue Sky" laws of any State.

            (d) Each Bank initially party to this Agreement hereby represents,
and each Person that became a Bank pursuant to an assignment permitted by this
Section 12 will, upon its becoming party to this Agreement, represent that it is
a commercial lender, other financial institution or other "accredited" investor
(as defined in SEC Regulation D) which makes loans in the ordinary course of its
business and that it will make or acquire Loans for its own account in the
ordinary course of such business, provided that subject to the preceding clauses
(a) and (b), the disposition of any promissory notes or other evidences of or
interests in Indebtedness held by such Bank shall at all times be within its
exclusive control.

            12.05 No Waiver; Remedies Cumulative. No failure or delay on the
part of the Administrative Agent or any Bank in exercising any right, power or
privilege hereunder or under any other Credit Document and no course of dealing
between the Borrower or any of its Subsidiaries and the Administrative Agent or
any Bank shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or privilege hereunder or under any other Credit
Document preclude any other or further exercise thereof or the exercise of any
other right, power or privilege hereunder or thereunder. The rights and remedies
herein expressly provided are cumulative and not exclusive of any rights or
remedies which the Administrative Agent or any Bank would otherwise have. No
notice to or demand on the Borrower or any of its Subsidiaries in any case shall
entitle the Borrower or any of its Subsidiaries to any other or further notice
or demand in similar or other circumstances or constitute a waiver of the rights
of the Administrative Agent or the Banks to any other or further action in any
circumstances without notice or demand.

            12.06 Payments Pro Rata. (a) The Administrative Agent agrees that
promptly after its receipt of each payment from or on behalf of the Borrower or
any of its Subsidiaries in respect of any Obligations of the Borrower or any of
its Subsidiaries hereunder, it shall distribute such payment to the Banks (other
than any Bank that has expressly



                                     -72-


0000DSZS.W51








waived its right to receive its pro rata share thereof) pro rata based upon
their respective shares, if any, of the Obligations with respect to which such
payment was received.

            (b) Each of the Banks agrees that, if it should receive any amount
hereunder (whether by voluntary payment, by realization upon security, by the
exercise of the right of setoff or banker's lien, by counterclaim or cross
action, by the enforcement of any right under the Credit Documents, or
otherwise) which is applicable to the payment of the principal of, or interest
on, the Loans, Unpaid Drawings or Fees, of a sum which with respect to the
related sum or sums received by other Banks is in a greater proportion than the
total of such Obligation then owed and due to such Bank bears to the total of
such Obligation then owed and due to all of the Banks immediately prior to such
receipt, then such Bank receiving such excess payment shall purchase for cash
without recourse or warranty from the other Banks an interest in the Obligations
of the Borrower or any of its Subsidiaries, respectively, to such Banks in such
amount as shall result in a proportional participation by all of the Banks in
such amount, provided that if all or any portion of such excess amount is
thereafter recovered from such Bank, such purchase shall be rescinded and the
purchase price restored to the extent of such recovery, but without interest.

            (c) Notwithstanding anything to the contrary contained herein, the
provisions of the preceding Sections 12.06(a) and (b) shall be subject to the
express provisions of this Agreement which require, or permit, differing
payments to be made to Non-Defaulting Banks as opposed to Defaulting Banks.

            12.07 Calculations; Computations. (a) The financial statements to be
furnished to the Banks pursuant hereto shall be made and prepared in accordance
with GAAP consistently applied throughout the periods involved (except as set
forth in the notes thereto or as otherwise disclosed in writing by the Borrower
to the Banks), provided that (x) except as otherwise specifically provided
herein, all computations determining compliance with Section 8, including
definitions used therein, shall utilize accounting principles and policies in
effect at the time of the preparation of, and in conformity with those used to
prepare, the September 30, 1996 historical financial statements of the Borrower
delivered to the Banks pursuant to Section 6.10(b) and (y) that if at any time
the computations determining compliance with Section 8 utilize accounting
principles different from those utilized in the financial statements furnished
to the Banks, such financial statements shall be accompanied by reconciliation
work-sheets. In calculating compliance with financial covenants (and related
definitions) hereunder based on the financial condition or performance of the
Borrower and its Subsidiaries, such calculations shall exclude the financial
condition and performance of all Unrestricted Subsidiaries.

            (b) All computations of interest and Fees hereunder shall be made on
the actual number of days elapsed over a year of 360 days.

            12.08 Governing Law; Submission to Jurisdiction; Venue; Waiver of
Jury Trial. (a) This Agreement and the other Credit Documents and the rights and
obligations of the parties hereunder and thereunder shall be construed in
accordance with and be



                                     -73-


0000DSZS.W51








governed by the law of the state of New York. Any legal action or proceeding
with respect to this Agreement or any other Credit Document may be brought in
the courts of the state of New York or of the United States for the Southern
District of New York, and, by execution and delivery of this Agreement, the
Borrower hereby irrevocably accepts for itself and in respect of its property,
generally and unconditionally, the jurisdiction of the aforesaid courts. The
Borrower further irrevocably consents to the service of process out of any of
the aforementioned courts in any such action or proceeding by the mailing of
copies thereof by registered or certified mail, postage prepaid, to the Borrower
located outside New York City and by hand delivery to the Borrower located
within New York City, at its address for notices pursuant to Section 12.03, such
service to become effective 30 days after such mailing. Nothing herein shall
affect the right of the Administrative Agent, any Bank to serve process in any
other manner permitted by law or to commence legal proceedings or otherwise
proceed against the Borrower in any other jurisdiction.

            (b) The Borrower hereby irrevocably waives any objection which it
may now or hereafter have to the laying of venue of any of the aforesaid actions
or proceedings arising out of or in connection with this Agreement or any other
Credit Document brought in the courts referred to in clause (a) above and hereby
further irrevocably waives and agrees not to plead or claim in any such court
that any such action or proceeding brought in any such court has been brought in
an inconvenient forum.

            (c) Each of the parties to this agreement hereby irrevocably waives
all right to a trial by jury in any action, proceeding or counterclaim arising
out of or relating to this agreement, the other credit documents or the
transactions contemplated hereby or thereby.

            12.09 Counterparts. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument. A set of counterparts
executed by all the parties hereto shall be lodged with the Borrower and the
Administrative Agent.

            12.10 Effectiveness. This Agreement shall become effective on the
date (the "Second Restatement Effective Date") on which the Borrower and each of
the Banks shall have signed a copy hereof (whether the same or different copies)
and shall have delivered the same to the Administrative Agent at the Payment
Office of the Administrative Agent or, in the case of the Banks, shall have
given to the Administrative Agent telephonic (confirmed in writing), written
telex or facsimile transmission notice (actually received) at such office that
the same has been signed and mailed to it.

            12.11 Headings Descriptive. The headings of the several sections and
subsections of this Agreement are inserted for convenience only and shall not in
any way affect the meaning or construction of any provision of this Agreement.

            12.12 Amendment or Waiver. (a) Neither this Agreement nor any other
Credit Document nor any terms hereof or thereof may be changed, waived,
discharged or



                                     -74-

terminated unless such change, waiver, discharge or termination is in writing
signed by the Borrower and the Required Banks, provided that no such change,
waiver, discharge or termination shall, without the consent of each Bank (other
than a Defaulting Bank) affected thereby, (i) extend the Maturity Date, or
reduce the rate or extend the time of payment of interest (other than as a
result of waiving the applicability of any post-default increase in interest
rates) or Fees thereon, or reduce the principal amount thereof, (ii) increase
the Commitment of any Bank over the amount thereof then in effect (it being
understood that a waiver of any Default or Event of Default or of a mandatory
reduction in the Total Commitment shall not constitute a change in the terms of
any Commitment of any Bank), (iii) amend, modify or waive any provision of this
Section, (iv) reduce the percentage specified in the definition of Required
Banks or (v) consent to the assignment or transfer by the Borrower of any of its
rights and obligations under this Agreement. No provision of Sections 2 or 11,
or any other provisions relating to any Letter of Credit Issuer or the
Administrative Agent may be modified without the consent of such Letter of
Credit Issuer or the Administrative Agent, respectively.

            (b) If, in connection with any proposed change, waiver, discharge or
termination to any of the provisions of this Agreement as contemplated by
clauses (i) through (vi), inclusive, of the first proviso to Section 12.12(a),
the consent of the Required Banks is obtained but the consent of one or more of
such other Banks whose consent is required is not obtained, then the Borrower
shall have the right to replace each such non-consenting Bank or Banks (so long
as all non-consenting Banks are so replaced) with one or more Replacement Banks
pursuant to Section 1.13 so long as at the time of such replacement, each such
Replacement Bank consents to the proposed change, waiver, discharge or
termination, provided that the Borrower shall not have the right to replace a
Bank solely as a result of the exercise of such Bank's rights (and the
withholding of any required consent by such Bank) pursuant to Section
12.12(a)(ii).

            12.13 Survival. All indemnities set forth herein including, without
limitation, in Section 1.10, 1.11, 4.04, 11.07 or 12.01 shall survive the
execution and delivery of this Agreement and the making and repayment of the
Loans.

            12.14 Domicile of Loans. Each Bank may transfer and carry its Loans
at, to or for the account of any branch office, subsidiary or Affiliate of such
Bank, provided that the Borrower shall not be responsible for costs arising
under Section 1.10 or 4.04 resulting from any such transfer (other than a
transfer pursuant to Section 1.12(a)) to the extent not otherwise applicable to
such Bank prior to such transfer.

            12.15 Confidentiality. Subject to Section 12.04, the Banks shall
hold all non-public information obtained pursuant to the requirements of this
Agreement in accordance with its customary procedure for handling confidential
information of this nature and in accordance with safe and sound banking
practices and in any event may make disclosure reasonably required by any bona
fide transferee or participant in connection with the contemplated transfer of
any Loans or participation therein (so long as such transferee or participant
agrees to be bound by the provisions of this Section 12.15) or as required or



                                     -75-


0000DSZS.W51








requested by any governmental agency or representative thereof or pursuant to
legal process, provided that, unless specifically prohibited by applicable law
or court order, each Bank shall notify the Borrower of any request by any
governmental agency or representative thereof (other than any such request in
connection with an examination of the financial condition of such Bank by such
governmental agency) for disclosure of any such non-public information prior to
disclosure of such information, and provided further that in no event shall any
Bank be obligated or required to return any materials furnished by the Borrower
or any Subsidiary.

            12.16 Registry. The Borrower hereby designates the Administrative
Agent to serve as the Borrower's agent, solely for purposes of this Section
12.16, to maintain a register (the "Register") on which it will record the
Commitments from time to time of each of the Banks, the Loans made by each of
the Banks and each repayment in respect of the principal amount of the Loans of
each Bank. Failure to make any such recordation, or any error in such
recordation shall not affect the Borrower's obligations in respect of such
Loans. With respect to any Bank, the transfer of the Commitments of such Bank
and the rights to the principal of, and interest on, any Loan made pursuant to
such Commitments shall not be effective until such transfer is recorded on the
Register maintained by the Administrative Agent with respect to ownership of
such Commitments and Loans and prior to such recordation all amounts owing to
the transferor with respect to such Commitments and Loans shall remain owing to
the transferor. The registration of assignment or transfer of all or part of any
Commitments and Loans shall be recorded by the Administrative Agent on the
Register only upon the acceptance by the Administrative Agent of a properly
executed and delivered Assignment and Assumption Agreement pursuant to Section
12.04(b). Coincident with the delivery of such an Assignment and Assumption
Agreement to the Administrative Agent for acceptance and registration of
assignment or transfer of all or part of a Loan, or as soon thereafter as
practicable, the assigning or transferor Bank shall surrender the Note
evidencing such Loan, and thereupon one or more new Notes in the same aggregate
principal amount shall be issued to the assigning or transferor Bank and/or the
new Bank.

19 December 1996



To each of the Banks party to the
Credit Agreement hereinafter referred to;
Christiania Bank og Kreditkasse, as Co-Arranger and
Documentation Agent; and Bankers Trust Company, 
as Co-Arranger and Administrative Agent 
c/o Bankers Trust Company 
130 Liberty Street 
New York, New York 10006

Gentlemen:

         I acted as counsel to Diamond Offshore Drilling, Inc., a Delaware
corporation (the "Company"), in connection with (i) the execution and delivery
of, and consummation of the transactions contemplated by, the Amended and
Restated Credit Agreement dated as of December 19, 1996 (the "Restated Credit
Agreement"), among the Company, the lending institutions from time to time a
party thereto (the "Banks"), Christiania Bank og Kreditkasse, New York Branch,
as Co-Arranger and Documentation Agent (in such capacity, the "Documentation
Agent") and Bankers Trust Company, as Co-Arranger and Administrative Agent (in
such capacity, the "Agent"), and (ii) the other documents and agreements
referenced herein. This opinion is delivered to you pursuant to 5.03(i) of the
Restated Credit Agreement. Capitalized terms defined in the Loan Documents (as
such term is defined below) and used but not otherwise defined herein are used
herein as so defined unless the context requires otherwise.

         In so acting, I have examined originals or copies, certified or
otherwise identified to my satisfaction, of: (a) the Restated Credit Agreement;
(b) the Notes; and (c) the Guaranty (the documents listed in clauses (a) through
(c) above being collectively referred to herein as the "Loan Documents"); and
(d) such corporate records, agreements,










documents and other instruments, and such certificates of comparable documents
of public officials and of officers and representatives of the Company and have
made also such inquiries of such officers and representatives as I have deemed
relevant and necessary as a basis for the opinions hereinafter set forth.

         In such examination, I have assumed the genuineness of all signatures,
the legal capacity of natural persons, the authenticity of all documents
submitted to me as originals, the conformity to original documents of all
documents submitted to me as certified or photostatic copies, and the
authenticity of the originals of such latter documents. As to all questions of
fact material to this opinion that have not been independently established, I
have relied upon certificates or comparable documents of officers and
representatives of the Company and upon the representations and warranties of
the Company and the Guarantors contained in the Loan Documents. As used herein,
"to my knowledge" or "of which I am aware" means the conscious awareness of
facts or other information by me.

         Based on the foregoing, and subject to the qualifications stated
herein, I am of the opinion that:

         1. Each Guarantor listed on Schedule I hereto is a corporation duly
organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation and has all requisite corporate power and
authority to own, lease and operate its properties and to carry on its business
as now being conducted.

         2. Each Guarantor listed on Schedule I hereto has all requisite
corporate power and authority to execute and deliver the Loan Documents to which
it is a party and to perform its obligations thereunder. The execution, delivery
and performance by each such Guarantor of the Loan Documents to which it is a
party and the consummation by each such Guarantor of the transactions
contemplated thereby have been duly authorized by all necessary corporate action
on the part of the respective Guarantor.

         3. Each of the Loan Documents to which each Guarantor listed on
Schedule I hereto is a party has been duly and validly executed and delivered by
the respective



                                        2





Guarantor and (assuming the due authorization, execution, and delivery thereof
by the Banks, the Documentation Agent and/or the Agent, as applicable) such Loan
Documents constitute the legal, valid, and binding obligation of the respective
Guarantor, enforceable against it in accordance with its terms, subject to
applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium, and similar laws affecting creditors' rights and remedies generally,
and subject, as to enforceability, to general principles of equity, including
principles of commercial reasonableness, good faith and fair dealing (regardless
of whether enforcement is sought in a proceeding at law or in equity) and except
that (A) rights to indemnification and contribution thereunder may be limited by
federal or state securities laws or public policy relating thereto and (B) no
opinion is expressed with respect to any set-off provisions contained in any of
the Loan Documents.

         4. The execution and delivery of the Loan Documents, the consummation
of the transactions contemplated thereby and the compliance by each Guarantor
listed on Schedule I hereto with any of the provisions thereof pertaining to the
respective Guarantor will not (a) conflict with, constitute a default under or
violate (i) any of the terms, conditions, or provisions of the certificate of
incorporation or by-laws of the respective Guarantor, (ii) any of the terms,
conditions, or provisions of any material document, agreement, or other
instrument to which the respective Guarantor is a party or by which it is bound,
of which I am aware, (iii) any Texas, Delaware corporate or federal law or
regulation (other than the Shipping Act, 1916, as amended, as to which I express
no opinion), or (iv) any judgment, writ, injunction, decree, order or ruling of
any federal or state court or governmental authority binding on the respective
Guarantor which remains unsatisfied and unperformed on the date hereof, of which
I am aware, except, in each case other than with respect to clause (i), any such
conflict, default or violation as would not impair the respective Guarantor's
ability to perform its obligations under the Loan Documents or have any material
adverse effect upon the consummation of the transactions contemplated thereby or
(b) result in the creation of any Lien upon the property of the respective
Guarantor under any material document, agreement or other instrument to which
the respective Guarantor is a party or by which it is bound, of which I am
aware.

         5. No consent, approval, waiver, license or authorization or other
action by or filing with any Texas, Delaware corporate or federal governmental
authority is required in connection with the execution and delivery by any
Guarantor listed in Schedule I hereto of any of the Loan Documents to which it
is a party, or the consummation by the



                                        3



respective Guarantor of the transactions contemplated thereby to be performed by
such Guarantor, except any consent, approval, waiver, license or authorization
or other action or filing required by federal and state securities, and blue sky
laws, and any maritime law or regulations, as to which I express no opinion.

         6. There is no litigation, proceeding, or governmental investigation
pending or overtly threatened against the Company or any of its subsidiaries
that relates to any of the transactions contemplated by the Loan Documents or
which, if adversely determined, is reasonably likely to have a material adverse
effect on the business, assets or financial condition of the Company and its
subsidiaries considered as a whole, except as disclosed in the Form 10-K of the
Company dated December 31, 1995 or the Form 10-Q of the Company dated September
30, 1996.

         The opinions expressed herein are limited to the laws of the State of
Texas, the corporate laws of the State of Delaware and the federal laws of the
United States, and I express no opinion as to the effect on the matters covered
by this letter of the laws of any other jurisdiction.

         The opinions expressed herein are rendered solely for your benefit and
the benefit of your respective participants and assigns in connection with the
transactions described herein. Those opinions may not be used or relied upon by
any other person, nor may this letter or any copies thereof be furnished to a
third party, filed with a governmental agency, quoted, cited or otherwise
referred to without my prior written consent, except in response to subpoena or
other legal process upon reasonable notice to me or in connection with
litigation relating to the Loan Documents.

To Each of the Banks Parties to the

Branch, as Co-Arranger and Documentation
Agent; The Fuji Bank, Limited,
as Co-Agent; and Bankers Trust Company, as
Co-Arranger and Administrative Agent
c/o Bankers Trust Company

New York, New York 10006

Gentlemen:

         We have acted as counsel to Diamond Offshore Drilling, Inc., a Delaware
corporation (the "Company"), in connection with the execution and delivery of,
and consummation of the transactions contemplated by, (i) the Credit Agreement,
dated as of February 8, 1996 (the "Original Credit Agreement"), among the
Company, the lending institutions that are parties thereto (the "Banks"),
Bankers Trust Company and Christiania Bank og Kreditkasse, New York Branch, as
co-arrangers (in such capacity, the "Co-Arrangers") and Bankers Trust Company,
as Administrative Agent (in such capacity, the "Agent"), (ii) the Amended and
Restated Credit Agreement, dated as of March 27, 1996 (the "Restated Credit
Agreement"), among the Company, Diamond Offshore Limited, a limited liability
company organized under the laws of the United Kingdom and an indirect wholly
owned subsidiary of the Company, the Banks, the Co-Arrangers and the Agent,
(iii) the Amended and Restated Credit Agreement, dated as of December 19, 1996
(the





"Second Restated Credit Agreement"), among the Company, the Banks, the
Co-Arrangers, Christiania Bank og Kreditkasse, New York Branch, as Documentation
Agent (in such capacity, the "Documentation Agent"), The Fuji Bank, Limited, as
Co-Agent (in such capacity, the "Co-Agents"), and the Agent, and (iv) the other
documents and agreements referenced herein. This opinion is delivered to you
pursuant to 5.04(ii) of the Second Restated Credit Agreement. Capitalized terms
defined in the Loan Documents (as such term is defined below) and used but not
otherwise defined herein are used herein as so defined.

         In so acting, we have examined originals or copies, certified or
otherwise identified to our satisfaction, of: (a) the Second Restated Credit
Agreement; (b) the Third Amended and Restated Guaranty, dated as of February 8,
1996, amended and restated as of March 27, 1996, further amended and restated as
of August 2, 1996 and further amended and restated as of December 19, 1996, made
by the Guarantors (as hereinafter defined) (the documents listed in clauses (a)
and (b) above being collectively referred to herein as the "Loan Documents");
and (c) such corporate records, agreements, documents and other instruments, and
such certificates or comparable documents of public officials and of officers
and representatives of the Company and have made also such inquiries of such
officers and representatives as we have deemed relevant and necessary as a basis
for the opinions hereinafter set forth.

         In such examination, we have assumed the genuineness of all signatures,
the legal capacity of natural persons, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified or photostatic copies, and the
authenticity of the originals of such latter documents. As to all questions of
fact material to this opinion that have not been independently established, we
have relied upon certificates or comparable documents of officers and
representatives of the Company and upon the representations and warranties of
the Company and the Guarantors contained in the Loan Documents. We have also
assumed (i) the due incorporation and valid existence of the Guarantors listed
on Schedule I (the "Guarantors"), (ii) that each such Guarantor has the
requisite corporate power and authority to enter into and perform the Loan
Documents to which it is a party and (iii) the due authorization, execution and
delivery of such Loan Documents by such Guarantors. As used herein, "of which we
are aware" means the conscious awareness of



                                        2




facts or other information by any lawyer in our firm actively involved in
negotiating the transactions contemplated by the Loan Documents.

         Based on the foregoing, and subject to the qualifications stated
herein, we are of the opinion that:

         1. The Company is a corporation duly organized, validly existing and in
good standing under the laws of the State of Delaware and has all requisite
corporate power and authority to own, lease and operate its properties and to
carry on its business as now being conducted. The Company is duly qualified to
transact business and is in good standing as a foreign corporation in the State
of Louisiana and is duly qualified to transact business as a foreign corporation
in the State of Texas.

         2. The Company has all requisite corporate power and authority to
execute and deliver the Loan Documents to which it is a party and to perform its
obligations thereunder. The execution, delivery and performance by the Company
of the Loan Documents to which it is a party and the consummation by the Company
of the transactions contemplated thereby have been duly authorized by all
necessary corporate action on the part of the Company.

         3. Each of the Loan Documents to which the Company is a party has been
duly and validly executed and delivered by the Company and (assuming the due
authorization, execution, and delivery thereof by the Banks, the Co-Arrangers,
the Documentation Agent, the Co-Agents and/or the Agent, as applicable) (i) each
such Loan Document and (ii) each Loan Document to which any Guarantor is a party
constitutes the legal, valid, and binding obligation of the Company or such
Guarantor, enforceable against it in accordance with its terms, subject to
applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium, and similar laws affecting creditors' rights and remedies generally,
and subject, as to enforceability, to general principles of equity, including
principles of commercial reasonableness, good faith and fair dealing (regardless
of whether enforcement is sought in a proceeding at law or in equity) and except
that (A) rights to indemnification and contribution thereunder may be limited by
federal or state securities laws or public policy relating thereto, (B) no
opinion is expressed with respect to any set-off provisions contained in any of
the Loan Documents, and (C) certain remedial provisions of the Loan Documents
are or may be unenforceable in whole or in







                                        3



part under the laws of the State of New York, but the inclusion of such
provisions does not affect the validity of the Loan Documents, and the Loan
Documents contain adequate provisions for the practical realization of the
rights and benefits afforded thereby.

         4. The execution and delivery of the Loan Documents, the consummation
of the transactions contemplated thereby and compliance by the Company with any
of the provisions thereof pertaining to the Company will not (a) conflict with,
constitute a default under or violate (i) any of the terms, conditions or
provisions of the Restated Certificate of Incorporation or by-laws of the
Company, (ii) any of the terms, conditions or provisions of any material
document, agreement or other instrument to which the Company is a party or by
which it is bound of which we are aware, (iii) any New York, Texas or Delaware
corporate or federal law or regulation (other than federal and state securities
or blue sky laws or maritime law or regulations, as to which we express no
opinion, and the Shipping Act, 1916, as amended, as to which we express no
opinion) or (iv) any judgment, writ, injunction, decree, order or ruling of any
federal or state court or governmental authority binding on the Company which
remains unsatisfied and unperformed on the date hereof and of which we are
aware, except, in each case other than with respect to clause (i), any such
conflict, default or violation as would not impair the Company's ability to
perform its obligations under the Loan Documents or have any material adverse
effect upon the consummation of the transactions contemplated thereby or (b)
result in the creation of any Lien upon the property of the Company under any
material document, agreement or other instrument to which the Company is a party
or by which it is bound of which we are aware.

         5. No consent, approval, waiver, license or authorization or other
action by or filing with any New York, Texas, or Delaware corporate or federal
governmental authority is required in connection with the execution and delivery
by the Company of the Second Restated Credit Agreement or the consummation by
the Company of the transactions contemplated thereby to be performed by the
Company, except for (i) those required by the Shipping Act, 1916, as amended, as
to which we express no opinion and (ii) any consent, approval, waiver, license
or authorization or other action or filing required by federal and state
securities and blue sky laws, and any maritime law or regulations, as to which
we express no opinion.



                                        4


         6. The Company is not (a) an "investment company" or an entity
"controlled" by an "investment company" under the Investment Company Act of
1940, as amended, and the rules and regulations promulgated by the Securities
and Exchange Commission (the "Commission") thereunder (the "Investment Company
Act") or (b) a "holding company" or a "subsidiary company" or an "affiliate" of
a "holding company" within the meaning of the Public Utility Holding Company Act
of 1935, as amended, and the rules and regulations promulgated by the Commission
thereunder (the "Holding Company Act"). In rendering the opinion in this
paragraph 6, we have assumed that Loews Corporation, a Delaware corporation, (x)
is not and is not controlled by an "investment company" under the Investment
Company Act and (y) is not a "holding company" or a "subsidiary company" or an
"affiliate" of a "holding company" under the Holding Company Act.

         The opinions expressed herein are limited to the laws of the State of
New York, the State of Texas, the corporate laws of the State of Delaware and
the federal laws of the United States, and we express no opinion as to the
effect on the matters covered by this letter of the laws of any other
jurisdiction.

         The opinions expressed herein are rendered solely for your benefit and
the benefit of your respective participants and assigns in connection with the
transactions described herein. Those opinions may not be used or relied upon by
any other person, nor may this letter or any copies thereof be furnished to a
third party, filed with a governmental agency, quoted, cited or otherwise
referred to without our prior written consent, except in response to subpoena or
other legal process upon reasonable notice to us or in connection with
litigation relating to the Loan Documents.

                                Very truly yours,

MSG:RBF                                               December 19, 1996




To:   The Administrative Agent and the various lending
      institutions (collectively, the "Banks") from time
      to time party to the Credit Agreement referred to below


re    Credit Agreement, dated as of
      February 8, 1996 and Amended
      and Restated as of March 27,
      1996 and further Amended and
      Restated as of December 19, 1996
      (as amended, the "Credit
      Agreement"), among Diamond Offshore
      Drilling, Inc. (the "Borrower")
      the Banks, Christiania Bank og
      Kreditkasse, New York Branch, as
      Co-Arranger and Documentation Agent,
      the Fuji Bank, Limited, as Co-Agent,
      and Bankers Trust Company, as
      Co-Arranger and Administrative Agent
- ------------------------------------------

Ladies and Gentlemen:

            We have acted as special counsel to the Administrative Agent in
connection with the execution and delivery of the Credit Agreement. This opinion
is delivered to you pursuant to Section 5.04(iii) of the Credit Agreement. Terms
used herein which are defined in the Credit Agreement shall have the respective
meanings set forth in the Credit Agreement unless otherwise defined herein.

            In connection with this opinion, we have examined the originals, or
certified, conformed or reproduction copies, of all records, agreements,
instruments and documents as we have deemed relevant or necessary as the basis
for the opinions hereinafter expressed. In stating our opinion, we have assumed
the genuineness of all signatures on original or certified copies, the
authenticity of documents submitted to us as originals and the conformity to
original or certified copies of all copies submitted to us as certified or
reproduction copies.

            We have also assumed, for purposes of the opinions expressed herein,
that the parties to the Credit Agreement have the corporate power and authority
to enter into and perform the Credit Agreement and that the Credit Agreement has
been duly authorized, executed and delivered by each such party.

            Based upon the foregoing, and subject to the limitations set forth
herein, we are of the opinion that the Credit Agreement constitutes the valid
and binding obligation of the Borrower enforceable in accordance with its terms
except to the extent that enforcement may be limited by applicable bankruptcy,
insolvency, reorganization or other similar laws affecting creditors' rights
generally and by equity principles (regardless of whether enforcement is sought
in equity or at law).

            We have not been requested to render and, with your permission, we
express no opinion as to the applicability to the obligations of the Borrower
under the Credit Agreement of Section 548 of the Bankruptcy Code and Article 10
of the New York Debtor & Creditor Law relating to fraudulent transfers and
obligations. We understand, without independent verification, that, to the
extent they have deemed necessary in the context of the proposed transaction,
the Banks have satisfied themselves on the basis of, among other things, the
financial information furnished to the Banks and their knowledge of the credit
facilities available to the Borrower, that neither the Borrower nor any of its
respective Subsidiaries is insolvent and that neither the Borrower nor any of
its respective Subsidiaries will be rendered insolvent by the transactions
contemplated by the Credit Agreement and the other Credit Documents and that,
after giving effect to such transactions, neither the Borrower nor any of its
respective Subsidiaries will be left with unreasonably small capital with which
to engage in its anticipated business and that neither the Borrower nor any of
its respective Subsidiaries will have intended to incur, or will have believed
it has incurred, debts beyond its ability to pay as such debts mature.

                           FORM OF GUARANTY


            THIRD AMENDED AND RESTATED GUARANTY, dated as of February 8, 1996,
Amended and Restated as of March 27, 1996, further Amended and Restated as of
August 2, 1996 and further Amended and Restated as of December 19, 1996, made by
the undersigned (each a "Guarantor" and collectively, the "Guarantors"). Except
as otherwise defined herein, terms used herein and defined in the Credit
Agreement (as hereinafter defined) shall be used herein as therein defined.


                         W I T N E S S E T H :


            WHEREAS, Diamond Offshore Drilling, Inc. (the "Borrower"), various
financial institutions from time to time party thereto (the "Banks"), Bankers
Trust Company and Christiania Bank og Kreditkasse, New York Branch, as
Co-Arrangers (the "Co-Arrangers"), Christiania Bank og Kreditkasse, New York
Branch, as Documentation Agent (the "Documentation Agent"), The Fuji Bank,
Limited, as Co-Agent (the "Co-Agent"), and Bankers Trust Company, as
Administrative Agent (the "Administrative Agent") have entered into a Credit
Agreement, dated as of February 8, 1996, Amended and Restated as of March 27,
1996 and further Amended and Restated as of December 19, 1996 (as amended,
modified or supplemented from time to time, the "Credit Agreement"), providing
for the making of Loans and the issuance of, and participation in, Letters of
Credit as contemplated therein (the Banks, the Co-Arrangers, the Administrative
Agent, each Letter of Credit Issuer, the Documentation Agent and the Co-Agent
are herein collectively called the "Creditors");

            WHEREAS, it is a condition to the making of Loans and the issuance
of, and participation in, Letters of Credit under the Credit Agreement that each
Guarantor shall have executed and delivered this Guaranty; and

            WHEREAS, each Guarantor will obtain benefits from the incurrence of
Loans by the Borrower and the issuance of Letters of Credit under the Credit
Agreement and, accordingly, desires to execute this Guaranty in order to satisfy
the conditions described in the preceding paragraph and to induce the Banks to
make Loans to the Borrower and the Letter of Credit Issuers to issue Letters of
Credit;

            NOW, THEREFORE, in consideration of the foregoing and other benefits
accruing to each Guarantor, the receipt and sufficiency of which are hereby
acknowledged, each Guarantor hereby makes the following representations and
warran-ties to the Creditors and hereby covenants and agrees with each Creditor
as follows:

            1. Each Guarantor, jointly and severally, irrevocably and
unconditionally, guarantees to the Creditors the full and prompt payment when
due (whether at the stated maturity, by acceleration or otherwise) of (x) the
principal of and interest on the Notes issued by, and the Loans made to, the
Borrower under the Credit Agreement, and all reimbursement obligations and
Unpaid Drawings with respect to the Letters of Credit issued under the Credit
Agreement and (y) all other obligations (including obligations which, but for
the automatic stay under Section 362(a) of the Bankruptcy Code, would become
due) and liabilities owing by the Borrower to the Creditors under the Credit
Agreement (including, without limitation, indemnities, Fees and interest
thereon) now existing or hereafter incurred under, arising out of or in
connection with the Credit Agreement or any other Credit Document and the due
performance and compliance with the terms of the Credit Documents by the
Borrower (all such principal, interest, liabilities and obligations being herein
collectively called the "Guaranteed Obligations"). Each Guarantor understands,
agrees and confirms that the Creditors may enforce this Guaranty up to the full
amount of the Guaranteed Obligations against each Guarantor without proceeding
against any other Guarantor or the Borrower, against any security for the
Guaranteed Obligations, or under any other guaranty covering all or a portion of
the Guaranteed Obligations. All payments by each Guarantor under this Guaranty
shall be made on the same basis as payments by the Borrower under Sections 4.03
and 4.04 of the Credit Agreement.

            2. Additionally, each Guarantor, jointly and severally,
unconditionally and irrevocably, guarantees the payment of any and all
Guaranteed Obligations of the Borrower to the Creditors whether or not due or
payable by the Borrower upon the occurrence in respect of the Borrower of any of
the events specified in Section 9.05 of the Credit Agreement, and
unconditionally and irrevocably, jointly and severally, promises to pay such
Guaranteed Obligations to the Creditors, or order, on demand, in lawful money of
the United States. This Guaranty shall constitute a guaranty of payment, and not
of collection.

            3. The liability of each Guarantor hereunder is exclusive and
independent of any security for or other guaranty of the indebtedness of the
Borrower whether executed by such Guarantor, any other Guarantor, any other
guarantor or by


                                -2-



0000DZ5Z.W51




                                                              EXHIBIT G
                                                              Page 3




any other party, and the liability of each Guarantor hereunder shall not be
affected or impaired by (a) any direction as to application of payment by the
Borrower or by any other party, (b) any other continuing or other guaranty,
undertaking or maximum liability of a guarantor or of any other party as to the
indebtedness of the Borrower, (c) any payment on or in reduction of any such
other guaranty or undertaking, (d) any dissolution, termination or increase,
decrease or change in personnel by the Borrower, (e) any payment made to any
Creditor on the indebtedness which any Creditor repays the Borrower pursuant to
court order in any bankruptcy, reorganization, arrangement, moratorium or other
debtor relief proceeding, and each Guarantor waives any right to the deferral or
modification of its obligations hereunder by reason of any such proceeding, (f)
any action or inaction by the Creditors as contemplated in Section 6 hereof, or
(g) any invalidity, irregularity or unenforceability of all or part of the
Guaranteed Obligations or of any security therefor.

            4. The obligations of each Guarantor hereunder are independent of
the obligations of any other Guarantor, any other guarantor or the Borrower, and
a separate action or actions may be brought and prosecuted against each
Guarantor whether or not action is brought against any other Guarantor, any
other guarantor or the Borrower and whether or not any other Guarantor, any
other guarantor or the Borrower be joined in any such action or actions. Any
payment by the Borrower or other circumstance which operates to toll any statute
of limitations as to the Borrower shall operate to toll the statute of
limitations as to each Guarantor with respect to the Obligations of the
Borrower.

            5. Each Guarantor hereby waives notice of acceptance of this
Guaranty and notice of any liability to which it may apply, and waives
promptness, diligence, presentment, demand of payment, protest, notice of
dishonor or nonpayment of any such liabilities, suit or taking of other action
by the Administrative Agent or any other Creditor against, and any other notice
to, any party liable thereon (including such Guarantor, any other guarantor or
the Borrower).

            6. Any Creditor may at any time and from time to time without the
consent of, or notice to, any Guarantor, without incurring responsibility to
such Guarantor, without impairing or releasing the obligations of such Guarantor
hereunder, upon or without any terms or conditions and in whole or in part:

            (a) change the manner, place or terms of payment of, and/or change
      or extend the time of payment of, renew or alter, any of the Guaranteed



0000DZ5Z.W51

      Obligations, any security therefor, or any liability incurred directly or
      indirectly in respect thereof, and the guaranty herein made shall apply to
      the Guaranteed Obligations as so changed, extended, renewed or altered;

            (b) sell, exchange, release, surrender, realize upon or otherwise
      deal with in any manner and in any order any property by whomsoever at any
      time pledged or mortgaged to secure, or howsoever securing, the Guaranteed
      Obligations or any liabilities (including any of those hereunder) incurred
      directly or indirectly in respect thereof or hereof, and/or any offset
      thereagainst;

            (c) exercise or refrain from exercising any rights against the
      Borrower or others or otherwise act or refrain from acting;

            (d) settle or compromise any of the Guaranteed Obligations, any
      security therefor or any liability (including any of those hereunder)
      incurred directly or indirectly in respect thereof or hereof, and may
      subordinate the payment of all or any part thereof to the payment of any
      liability (whether due or not) of the Borrower to creditors of the
      Borrower;

            (e) apply any sums by whomsoever paid or howsoever realized to any
      liability or liabilities of the Borrower to the Creditors regardless of
      what liabilities of the Borrower remain unpaid;

            (f) release or substitute any one or more endorsers, guarantors, any
      Credit Party or other obligors;

            (g) consent to or waive any breach of, or any act, omission or
      default under, any of the Credit Documents or any of the instruments or
      agreements referred to therein, or otherwise amend, modify or supplement
      any of the Credit Documents or any of such other instruments or
      agreements; and/or

            (h) act or fail to act in any manner referred to in this Guaranty
      which may deprive such Guarantor of its right to subrogation against the
      Borrower to recover full indemnity for any payments made pursuant to this
      Guaranty.

            7. No invalidity, irregularity or unenforceability of all or any
part of the Guaranteed Obligations or of any security therefor shall affect,
impair or be a defense to this Guaranty, and this Guaranty shall be primary,
absolute and unconditional



0000DZ5Z.W51




                                                              EXHIBIT G
                                                              Page 5




notwithstanding the occurrence of any event or the existence of any other
circumstances which might constitute a legal or equitable discharge of a surety
or guarantor except, with respect to any Guarantor, payment in full of the
Guaranteed Obligations guaranteed by it.

            8. This Guaranty is a continuing one and all liabilities to which it
applies or may apply under the terms hereof shall be conclusively presumed to
have been created in reliance hereon. No failure or delay on the part of any
Creditor in exercising any right, power or privilege hereunder shall operate as
a waiver thereof; nor shall any single or partial exercise of any right, power
or privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
expressly specified are cumulative and not exclusive of any rights or remedies
which any Creditor would otherwise have. No notice to or demand on any Guarantor
in any case shall entitle such Guarantor to any other further notice or demand
in similar or other circumstances or constitute a waiver of the rights of any
Creditor to any other or further action in any circumstances without notice or
demand. It is not necessary for any Creditor to inquire into the capacity or
powers of the Borrower or any of its Subsidiaries or the officers, directors,
partners or agents acting or purporting to act on its behalf, and any
indebtedness made or created in reliance upon the professed exercise of such
powers shall be guaranteed hereunder.

            9. Any indebtedness of the Borrower now or hereafter held by any
Guarantor is hereby subordinated to the indebtedness of the Borrower to the
Creditors; and such indebtedness of the Borrower to any Guarantor, if the
Administrative Agent, after an Event of Default has occurred, so requests, shall
be collected, enforced and received by such Guarantor as trustee for the
Creditors and be paid over to the Creditors on account of the indebtedness of
the Borrower to the Creditors, but without affecting or impairing in any manner
the liability of such Guarantor under the other provisions of this Guaranty.
Prior to the transfer by any Guarantor of any note or negotiable instrument
evidencing any indebtedness of the Borrower to such Guarantor, such Guarantor
shall mark such note or negotiable instrument with a legend that the same is
subject to this subordination. Without limiting the generality of the foregoing,
each Guarantor hereby agrees with the Creditors that it will not exercise any
right of subrogation which it may at any time otherwise have as a result of this
Guaranty (whether contractual, under Section 509 of the Bankruptcy Code or
otherwise) until all Guaranteed Obligations have been irrevocably paid in full
in cash.

                                                              Page 6




            10. (a) Each Guarantor waives any right (except as shall be required
by applicable law and cannot be waived) to require the Creditors to (A) proceed
against the Borrower, any other Guarantor, any other guarantor or any other
party, (B) proceed against or exhaust any security held from the Borrower, any
other Guarantor, any other guarantor or any other party or (C) pursue any other
remedy in the Creditors' power whatsoever. Each Guarantor waives any defense
based on or arising out of any defense of the Borrower, any other Guarantor, any
other guarantor or any other party other than payment in full of its respective
Guaranteed Obligations, including without limitation any defense based on or
arising out of the disability of the Borrower, any other Guarantor, any other
guarantor or any other party, or the unenforceability of its respective
Guaranteed Obligations or any part thereof from any cause, or the cessation from
any cause of the liability of the Borrower other than payment in full of its
respective Guaranteed Obligations. The Creditors may, at their election,
foreclose on any security held by the Administrative Agent or the other
Creditors by one or more judicial or nonjudicial sales, whether or not every
aspect of any such sale is commercially reasonable (to the extent such sale is
permitted by applicable law), or exercise any other right or remedy the
Creditors may have against the Borrower or any other party, or any security,
without affecting or impairing in any way the liability of any Guarantor
hereunder except to the extent the respective Guaranteed Obligations have been
paid in full. Each Guarantor waives any defense arising out of any such election
by the Creditors, even though such election operates to impair or extinguish any
right of reimbursement or subrogation or other right or remedy of such Guarantor
against the Borrower or any other party or any security.

            (b) Each Guarantor waives all presentments, demands for performance,
protests and notices, including without limitation notices of nonperformance,
notices of protest, notices of dishonor, notices of acceptance of this Guaranty,
and notices of the existence, creation or incurring of new or additional
indebtedness. Each Guarantor assumes all responsibility for being and keeping
itself informed of the Borrower's financial condition and assets, and of all
other circumstances bearing upon the risk of nonpayment of any of the Guaranteed
Obligations and the nature, scope and extent of the risks which such Guarantor
assumes and incurs hereunder, and agrees that the Creditors shall have no duty
to advise any Guarantor of information known to them regarding such
circumstances or risks.

            11. The Creditors agree that this Guaranty may be enforced only by
the action of the Administrative Agent acting upon the instructions of the
Required Banks and that no Creditor shall have any right individually to seek to
enforce or to enforce



0000DZ5Z.W51

this Guaranty, it being understood and agreed that such rights and remedies may
be exercised by the Administrative Agent for the benefit of the Creditors upon
the terms of this Guaranty. The Creditors further agree that this Guaranty may
not be enforced against any director, officer, employee or stockholder of any
Guarantor (except to the extent such stockholder is also a Guarantor hereunder).

            12. Each Guarantor covenants and agrees that on and after the date
hereof and until the termination of the Total Commitment and when no Letter of
Credit or Note remains outstanding and all Guaranteed Obligations have been paid
in full, such Guarantor shall take, or will refrain from taking, as the case may
be, all actions that are necessary to be taken or not taken so that no violation
of any provision, covenant or agreement contained in Section 7 or 8 of the
Credit Agreement, and so that no Event of Default, is caused by the actions of
such Guarantor or any of its Subsidiaries.

            13. The Guarantors hereby jointly and severally agree to pay all
reasonable out-of-pocket costs and expenses (x), after an Event of Default shall
have occurred and be continuing, of each Creditor in connection with the
enforcement of this Guaranty and the protection of such Creditor's rights
hereunder (including, without limitation, the reasonable fees and disbursements
of counsel (including in-house counsel) employed by any of the Creditors) and
(y) of the Administrative Agent in connection with any amendment, waiver or
consent relating hereto (including, without limitation, the reasonable fees and
disbursements of counsel (including in-house counsel) employed by the
Administrative Agent.

            14. This Guaranty shall be binding upon each Guarantor and its
successors and assigns and shall inure to the benefit of the Creditors and their
successors and assigns.

            15. Neither this Guaranty nor any provision hereof may be changed,
waived, discharged or terminated except with the written consent of the Required
Banks (or to the extent required by Section 12.12 of the Credit Agreement, with
the written consent of each Bank) and each Guarantor affected thereby (it being
understood that the addition or release of any Guarantor hereunder shall not
constitute a change, waiver, discharge or termination affecting any Guarantor
other than the Guarantor so added or released).

            16. Each Guarantor acknowledges that an executed (or conformed) copy
of each of the Credit Documents has been made available to its principal
executive officers and such officers are familiar with the contents thereof.

            17. In addition to any rights now or hereafter granted under
applicable law (including, without limitation, Section 151 of the New York
Debtor and Creditor Law) and not by way of limitation of any such rights, upon
the occurrence and during the continuance of an Event of Default (such term to
mean and include any "Event of Default" as defined in the Credit Agreement
continuing after any applicable grace period), each Creditor is hereby
authorized at any time or from time to time, without notice to any Guarantor or
to any other Person, any such notice being expressly waived, to set off and to
appropriate and apply any and all deposits (general or special) and any other
indebtedness at any time held or owing by such Creditor to or for the credit or
the account of such Guarantor, against and on account of the obligations and
liabilities of such Guarantor to such Creditor under this Guaranty, irrespective
of whether or not such Creditor shall have made any demand hereunder and
although said obligations, liabilities, deposits or claims, or any of them,
shall be contingent or un-matured.

            18. All notices, requests, demands or other communications pursuant
hereto shall be deemed to have been duly given or made when delivered to the
Person to which such notice, request, demand or other communication is required
or permitted to be given or made under this Guaranty, addressed to such party at
(i) in the case of any Creditor, as provided in the Credit Agreement and (ii) in
the case of any Guarantor, at its address set forth opposite its signature
below; or in any case at such other address as any of the Persons listed above
may hereafter notify the others in writing.

            19. If claim is ever made upon any Creditor for repayment or
recovery of any amount or amounts received in payment or on account of any of
the Guaranteed Obligations and any of the aforesaid payees repays all or part of
said amount by reason of (a) any judgment, decree or order of any court or
administrative body having jurisdiction over such payee or any of its property
or (b) any settlement or compromise of any such claim effected by such payee
with any such claimant (including the Borrower), then and in such event each
Guarantor agrees that any such judgment, decree, order, settlement or compromise
shall be binding upon such Guarantor, notwithstanding any revocation hereof or
of any other instrument evidencing any liability of the Borrower, and such
Guarantor shall be and remain liable to the aforesaid



0000DZ5Z.W51

payees hereunder for the amount so repaid or recovered to the same extent as if
such amount had never originally been received by any such payee.

            20. (A) THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE
CREDITORS AND OF THE UNDERSIGNED HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK. Any legal action or
proceeding with respect to this Guaranty or any other Credit Document may be
brought in the courts of the State of New York or of the United States of
America for the Southern District of New York, and, by execution and delivery of
this Guaranty, each Guarantor hereby accepts for itself and in respect of its
property, generally and unconditionally, the jurisdiction of the aforesaid
courts and hereby irrevocably waives any right it may have to object to the
laying of venue of any such action or proceeding in the aforesaid courts and
hereby further irrevocably waives and agrees not to plead or claim that any such
action or proceeding has been brought in an inconvenient forum. Each Guarantor
hereby irrevocably designates, appoints and empowers the Borrower, with offices
on the date hereof at 15415 Katy Freeway, Suite 400, Houston, Texas 77094 as its
designee, appointee and agent to receive, accept and acknowledge for any on its
behalf, and in respect of its property, service or any and all legal process,
summons, notices and documents which may be served in any such action or
proceeding. If for any reason such designee, appointee and agent shall cease to
be available to act as such, each Guarantor agrees to designate a new designee,
appointee and agent in New York City on the terms and for the purposes of this
provision satisfactory to the Administrative Agent for the Banks under this
Guaranty. Each Guarantor further irrevocably consents to the service of process
out of any of the aforementioned courts in any such action or proceeding by the
mailing of copies thereof by registered or certified mail, postage prepaid, to
each Guarantor at its address set forth opposite its signature below. Nothing
herein shall affect the right of any of the Creditors to serve process in any
other manner permitted by law or to commence legal proceedings or otherwise
proceed against each Guarantor in any other jurisdiction.

            (b) Each Guarantor hereby irrevocably waives any objection which it
may now or hereafter have to the laying of venue of any of the aforesaid actions
or proceedings arising out of or in connection with this Guaranty or any other
credit document brought in the courts referred to in clause (a) above and hereby
further irrevocably waives and agrees not to plead or claim in any such court
that such action or proceeding brought in any such court has been brought in an
inconvenient forum.

            21. In the event that all of the capital stock of one or more
Guarantors is sold or otherwise disposed of or liquidated in compliance with the
requirements of Section 8.02 of the Credit Agreement (or such sale or other
disposition has been approved in writing by the Required Banks (or all Banks if
required by Section 12.12 of the Credit Agreement)) and the proceeds of such
sale, disposition or liquidation are applied in accordance with the provisions
of the Credit Agreement, to the extent applicable, such Guarantor shall be
released from this Guaranty and this Guaranty shall, as to each such Guarantor
or Guarantors, terminate, and have no further force or effect (it being
understood and agreed that the sale of any Person that owns, directly or
indirectly, the capital stock of any Guarantor shall be deemed to be a sale of
such Guarantor for the purposes of this Section 21).

            22. At any time a payment in respect of (i) the Guaranteed
Obligations is made under this Guaranty, the right of contribution, if any, of
each Guarantor against any other Guarantor required to make any payment to such
Guarantor pursuant to this Section 22 (a "Contributor") shall be determined as
provided in the immediately following sentence, with the right of contribution
of each Guarantor to be revised and restated as of each date on which a payment
(a "Relevant Payment") is made on the Guaranteed Obligations under this
Guaranty. At any time that a Relevant Payment is made by a Guarantor that
results in the aggregate payments made by such Guarantor in respect of the
Guaranteed Obligations to and including the date of the Relevant Payment
exceeding such Guarantor's Contribution Percentage (as hereinafter defined) of
the aggregate payments made by all Guarantors in respect of the Guaranteed
Obligations to and including the date of the Relevant Payment (such excess, the
"Aggregate Excess Amount"), each such Guarantor shall have a right of
contribution against each Contributor who has made payments in respect of the
Guaranteed Obligations to and including the date of the Relevant Payment in an
aggregate amount less than such Contributor's Contribution Percentage of the
aggregate payments made to and including the date of the Relevant Payment by all
Guarantors in respect of the Guaranteed Obligations (the aggregate amount of
such deficit, the "Aggregate Deficit Amount") in an amount equal to (x) a
fraction the numerator of which is the Aggregate Excess Amount of such Guarantor
and the denominator of which is the Aggregate Excess Amount of all Guarantors
multiplied by (y) the Aggregate Deficit Amount of such Contributor. A
Guarantor's right of contribution, if any, pursuant to the preceding sentences
shall arise at the time of each computation, subject to adjustment to the time
of any subsequent computation; provided, that no Guarantor may take any action
to enforce such right until the Guaranteed Obligations have been paid in full,
all Letters of Credit have terminated and the Total Commitment has been
terminated, it being

expressly recognized and agreed by all parties hereto that any Guarantor's right
of contribution arising pursuant to this Section 22 against any Contributor
shall be expressly junior and subordinate to such Contributor's obligations and
liabilities in respect of the Guaranteed Obligations and any other obligations
owing under this Guaranty. As used in this Agreement, (i) each Contributor's
"Contribution Percentage" shall mean the percentage obtained by dividing (x) the
Adjusted Net Worth of such Contributor by (y) the aggregate Adjusted Net Worth
of all Guarantors of the respective Guaranteed Obligations; (ii) the "Adjusted
Net Worth" of each Guarantor shall mean the greater of (x) the Net Worth of such
Guarantor or (y) zero; and (iii) the "Net Worth" of each Guarantor shall mean
the amount by which the fair salable value of such Guarantor's assets on the
Second Restatement Effective Date exceeds its existing debts and other
liabilities (including contingent liabilities, but without giving effect to any
Guaranteed Obligations arising under this Guaranty), in each case after giving
effect to all transactions occurring on the Second Restatement Effective Date.

            23. Each Guarantor recognizes and agrees that, except for any right
of contribution arising pursuant to Section 22, until the Guaranteed Obligations
have been paid in full, each Guarantor who makes any payment in respect of the
Guaranteed Obligations shall have no right of contribution or subrogation
against any other Guarantor in respect of such payment, any such right of
contribution or subrogation arising under law or otherwise being expressly
waived by all Guarantors until the Guaranteed Obligations have been paid in
full.

            24. Each Guarantor recognizes and acknowledges that the rights to
contribution arising hereunder shall constitute an asset in favor of the party
entitled to such contribution. In this connection, each Guarantor has the right
to waive its contribution right against any other Guarantor to the extent that
after giving effect to such waiver such Guarantor would remain solvent, in the
determination of the Required Banks.

            25. This Guaranty may be executed in any number of counterparts and
by the different parties hereto on separate counterparts, each of which when so
executed and delivered shall be an original, but all of which shall together
constitute one and the same instrument. A set of counterparts executed by all
the parties hereto shall be lodged with the Guarantors and the Administrative
Agent.

            26. EACH GUARANTOR HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO A TRIAL
BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO
THIS GUARANTY, THE OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED
HEREBY OR THEREBY.

            27. It is understood and agreed that any Subsidiary of the Borrower
that is required to execute a counterpart of this Guaranty pursuant to the
Credit Agreement shall automatically become a Guarantor hereunder by executing a
counterpart hereof and delivering the same to the Administrative Agent.

            28. All payments made by any Guarantor hereunder will be made
without setoff, counterclaim or other defense.
