                             UNDERWRITING AGREEMENT


SECTION 1.    Introductory.

         Diamond Offshore Drilling, Inc., a Delaware corporation ("Company"),
proposes to issue and sell from time to time certain of its unsecured debt
securities, preferred stock, common stock, par value $.01 per share ("Common
Stock") and warrants to purchase debt securities and warrants to purchase
preferred stock (and any debt securities, preferred stock or Common Stock
issuable upon conversion or exercise of such securities) registered under the
registration statement referred to in Section 2(a) ("Registered Securities").
The Registered Securities constituting debt securities will be issued under one
or more indentures or supplemental indentures (each, an "Indenture"), between
the Company and a trustee selected by the Company, in one or more series, which
series may vary as to interest rates, maturities, redemption provisions, selling
prices and other terms.  The Registered Securities constituting warrants will be
issued under one or more Warrant Agreements (each, a "Warrant Agreement"),
between the Company and a warrant agent to be selected by the Company, in one or
more series, which series may vary as to exercise price, exercise date,
expiration date and other terms.  The Registered Securities constituting
preferred stock may be issued in one or more series, which series may vary as to
dividend rates, redemption provisions, selling prices and other terms.
Particular series or offerings of Registered Securities will be sold pursuant to
a Terms Agreement referred to in Section 3, for resale in accordance with terms
of offering determined at the time of sale.

        The Registered Securities involved in any such offering are hereinafter
referred to as the "Firm Securities" and, together with any Optional Securities
(as defined in Section 3 below), the "Offered Securities".  The firm or firms
which agree to purchase the Offered Securities are hereinafter referred to as
the "Underwriters" of such securities, and the representative or
representatives of the Underwriters, if any, specified in a Terms Agreement
referred to in Section 3 are hereinafter referred to as the "Representatives";
provided, however, that if the Terms Agreement does not specify any
representative of the Underwriters, the term "Representatives", as used in this
Agreement (other than in Sections 2(b), 5(c) and 6 and the second sentence of
Section 3), shall mean the Underwriters.

SECTION 2.    Representations and Warranties of the Company.

        The Company, as of the date of each Terms Agreement referred to in
Section 3, represents and warrants to, and agrees with, each Underwriter that:

                 (a)     A registration statement (No. 333-19987), including a
prospectus, relating to the Registered Securities has been filed with the
Securities and Exchange Commission ("Commission") and has become effective.
Such registration statement, as amended at the time of any Terms Agreement
referred to in Section 3, is hereinafter referred to as the "Registration
Statement", and the prospectus included in such Registration Statement, as
supplemented as contemplated by Section 3 to reflect the terms of the Offered
Securities (if they are debt securities, warrants or preferred stock) and the
terms of the offering of the Offered Securities, as first filed with the
Commission pursuant to and in accordance with Rule 424(b) ("Rule 424(b)") under
the Securities Act of 1933 ("Act"), including all material incorporated by
reference therein, is hereinafter referred to as the "Prospectus". No document
has been or will be prepared or distributed in reliance on Rule 434 under the
Act.

liability or claim would individually or in the aggregate have a material
adverse effect on the Company and its subsidiaries taken as a whole; and the
Company is not aware of any pending investigation which might lead to such a
claim.

                 (u)     There are no pending actions, suits or proceedings
against or affecting the Company, any of its subsidiaries or any of their
respective properties except as disclosed in the Prospectus, or as individually
or in the aggregate do not now have and, to the best knowledge of the Company,
are not reasonably expected in the future to have a material adverse effect on
the condition (financial or other), business, properties or results of
operations of the Company and its subsidiaries taken as a whole, or would
materially and adversely affect the ability of the Company to perform its
obligations under the Indenture (if the Offered Securities are debt
securities), the Warrant Agreement (if the Offered Securities are warrants),
the Terms Agreement (including the provisions of this Agreement) or any Delayed
Delivery Contracts, or which are otherwise material in the context of the sale
of the Offered Securities; and no such actions, suits or proceedings are, to
the Company's knowledge, threatened or contemplated.

                 (v)     The financial statements included in the Registration
Statement and Prospectus present fairly in all material respects the financial
position of the Company and its consolidated subsidiaries as of the dates shown
and their results of operations and cash flows for the periods shown, and such
financial statements have been prepared in conformity with the generally
accepted accounting principles in the United States applied on a consistent
basis; any schedules included in the Registration Statement present fairly the
information required to be stated therein; and if pro forma financial
statements are included in the Registration Statement and Prospectus: the
assumptions used in preparing the pro forma financial statements included in
the Registration Statement and the Prospectus provide a reasonable basis for
presenting the significant effects directly attributable to the transactions or
events described therein, the related pro forma adjustments give appropriate
effect to those assumptions in all material respects, and the pro forma columns
therein reflect the proper application in all material respects of those
adjustments to the corresponding historical financial statement amounts.

                 (w)     Except as disclosed in the Prospectus, since the date
of the latest audited financial statements included in the Prospectus there has
been no material adverse change, nor any development or event involving a
prospective material adverse change, in the condition (financial or other),
business, properties or results of operations of the Company and its
subsidiaries taken as a whole, and there has been no dividend or distribution
of any kind declared, paid or made by the Company on any class of its capital
stock.

                 (x)     The Company is not and, after giving effect to the
offering and sale of the Offered Securities and the application of the proceeds
thereof as described in the Prospectus, will not be (i) an "investment company"
or a company "controlled" by an "investment company" within the meaning of the
Investment Company Act of 1940, as





                                       5

amended (the "Investment Company Act"), or (ii) 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 (the "Holding
Company Act").

                 (y)     Neither the Company nor any of its affiliates does
business with the government of Cuba or with any person or affiliate located in
Cuba within the meaning of Section 517.075, Florida Statutes and the Company
agrees to comply with such Section if prior to the completion of the
distribution of the Offered Securities it commences doing such business.

                 (z)     No consent or approval of any federal governmental
agency with respect to any federal maritime law matter is required in
connection with performance by the Company of its obligations under the Terms
Agreement (including the provisions of this Agreement) or the issuance and sale
of the Offered Securities; and neither the issue, offer, sale or delivery by
the Company of the Offered Securities pursuant to the Terms Agreement
(including the provisions of this Agreement) or the execution, delivery, and
performance by the Company and the consummation of the transactions
contemplated thereby will violate any existing federal maritime laws,
including, without limitation, the Shipping Act, 1916, as amended, and the
rules and regulations of the Maritime Administration (MarAd) and the United
States Coast Guard.

Section 3.    Purchase and Offering of Offered Securities.

        The obligation of the Underwriters to purchase the Firm Securities will
be evidenced by an agreement or exchange of other written communications
("Terms Agreement") at the time the Company determines to sell the Firm
Securities.  The Terms Agreement will incorporate by reference the provisions
of this Agreement, except as otherwise provided therein, and will specify the
firm or firms which will be Underwriters, the names of any Representatives, the
aggregate principal amount or number of Firm Securities to be purchased by each
Underwriter, the purchase price to be paid by the Underwriters and (if the Firm
Securities are debt securities, warrants or preferred stock) the terms of the
Firm Securities not already specified (in the Indenture, in the case of Firm
Securities that are debt securities or in the Warrant Agreement, in the case of
Firm Securities that are warrants), including, but not limited to, interest
rate (if debt securities), dividend rate (if preferred stock), maturity (if
debt securities), any redemption, conversion or exercise provisions and any
sinking fund requirements and whether any of the Firm Securities may be sold to
institutional investors pursuant to Delayed Delivery Contracts (as defined
below).  The Terms Agreement will also specify the time and date of delivery
and payment (such time and date, or such other time not later than seven full
business days thereafter as the Underwriter first named in the Terms Agreement
(the "Lead Underwriter") and the Company agree as the time for payment and
delivery, being herein and in the Terms Agreement referred to as the "First
Closing Date"), the place of delivery and payment and any details of the terms
of offering that should be reflected in the prospectus supplement relating to
the offering of the Offered Securities.  For purposes of Rule 15c6-1 under the
Securities Exchange Act of 1934, the First Closing Date (if later than the
otherwise applicable settlement date) shall be the date for payment of funds
and delivery of securities for all the Offered Securities sold pursuant to the
offering, other than Contract Securities for which payment of funds and
delivery of securities shall be as hereinafter provided.  The obligations of
the Underwriters to purchase the Firm Securities will be several and not joint.
It is understood that the Underwriters propose to offer the Offered Securities
for sale as set forth in the Prospectus.

        If the Firm Securities are debt securities and the Terms Agreement 
specifies "Book-Entry Only" settlement or otherwise states that the
provisions of this paragraph shall apply, the Company will deliver against
payment of the purchase price the Firm Securities being purchased on such
Closing Date in the form of one or more permanent global Securities in
definitive form (the "Global Securities") deposited with the Trustee as
custodian for The Depository Trust Company ("DTC") and registered in the name
of Cede & Co., as nominee for DTC. Interests in any permanent Global Securities
will be held only in book-entry form through DTC, except in the limited
circumstances described in the Prospectus. Payment for the Firm Securities
shall be made by the Underwriters in Federal (same day) funds by official check
or checks or wire transfer to an account previously designated to the Lead
Underwriter by the Company at a bank acceptable to the Lead Underwriter, in
each case drawn to the order of the Company at the place of payment specified
in the Terms Agreement on such Closing Date, against delivery to the Trustee as
custodian for DTC of the Global Securities representing all of the Firm
Securities.





                                       6
<PAGE>   7
        The Company may specify in the Terms Agreement applicable to any
Offered Securities that the Company thereby grants to the Underwriters the
right to purchase at their election up to the aggregate principal amount of
debt securities, number of shares of preferred stock or Common Stock or number
of warrants ("Optional Securities") set forth in such Terms Agreement, on the
terms set forth in the first paragraph of this Section 3.  Any such election
may be exercised only by written notice from the Lead Underwriter to the
Company, given within the period specified in the Terms Agreement, setting
forth the aggregate principal amount or number of Optional Securities purchased
and the date on which such Optional Securities are to be delivered as
determined by the Lead Underwriter.

        The Company agrees to sell to the Underwriters the aggregate principal
amount or number of Optional Securities specified in such notice and the
Underwriters agree, severally and not jointly, to purchase such Optional
Securities.  Such Optional Securities shall be purchased for the account of
each Underwriter in the same proportion as the aggregate principal amount or
number of Firm Securities set forth opposite such Underwriter's name in such
Terms Agreement bears to the aggregate principal amount or number of Firm
Securities (subject to adjustment by the Lead Underwriter to eliminate
fractions) and may be purchased by the Underwriters only for the purpose of
covering over-allotments made in connection with the sale of the Firm
Securities.  No Optional Securities shall be sold or delivered unless the Firm
Securities previously have been, or simultaneously are, sold and delivered.
The right to purchase the Optional Securities or any portion thereof may be
exercised from time to time and to the extent not previously exercised may be
surrendered and terminated at any time upon notice by the Lead Underwriter to
the Company.

        Each time for the delivery of and payment for the Optional Securities,
being herein referred to as an "Optional Closing Date", which may be the First
Closing Date (the First Closing Date and each Optional Closing Date, if any,
being sometimes referred to as a "Closing Date"), shall be determined by the
Lead Underwriter but shall be not later than five full business days after
written notice of election to purchase Optional Securities is given.  The
Company will deliver the Optional Securities being purchased on each Optional
Closing Date to the Representatives for the accounts of the several
Underwriters against payment of the purchase price therefor in the same manner
as the Firm Securities.

        If the Terms Agreement provides for sales of Offered Securities
pursuant to delayed delivery contracts, the Company authorizes the Underwriters
to solicit offers to purchase Offered Securities pursuant to delayed delivery
contracts substantially in the form of Annex I attached hereto ("Delayed
Delivery Contracts") with such changes therein as the Company may authorize or
approve.  Delayed Delivery Contracts are to be with institutional investors,
including commercial and savings banks, insurance companies, pension funds,
investment companies and educational and charitable institutions.  On the
Closing Date the Company will pay, as compensation, to the Representatives for
the accounts of the Underwriters, the fee set forth in such Terms Agreement in
respect of the principal amount, number, or number of shares of Offered
Securities to be sold pursuant to Delayed Delivery Contracts ("Contract
Securities").  The Underwriters will not have any responsibility in respect of
the validity or the performance of Delayed Delivery Contracts.  If the Company
executes and delivers Delayed Delivery Contracts, the Contract Securities will
be deducted from the Offered Securities to be purchased by the several
Underwriters and the aggregate principal amount, number or number of shares of
Offered Securities to be purchased by each Underwriter will be reduced pro rata
in proportion to the principal amount, number or number of shares of Offered
Securities set forth opposite each Underwriter's name in such Terms Agreement,
except to the extent that the Lead Underwriter determines that such reduction
shall be otherwise than pro rata and so advise the Company.  The Company will
advise the Lead Underwriter not later than the business day prior to the
Closing Date of the principal amount or number of shares of Contract
Securities.

SECTION 4.       Certain Agreements of the Company.

        The Company agrees with the several Underwriters that it will furnish
to counsel for the Underwriters, one signed copy of the registration statement
relating to the Registered Securities, including all exhibits, in the form it
became effective and of all amendments thereto and that, in connection with
each offering of Offered Securities:

                 (a)     The Company will file the Prospectus with the
Commission pursuant to and in accordance with Rule 424(b)(2) (or, if applicable
and if consented to by the Lead Underwriter, subparagraph (5)) not later than
the second business day following the execution and delivery of the Terms
Agreement.





                                       7
<PAGE>   8
                 (b)     The Company will advise the Lead Underwriter promptly
of any proposal to amend or supplement the Registration Statement or the
Prospectus and will afford the Lead Underwriter a reasonable opportunity to
comment on any such proposed amendment or supplement; and the Company will also
advise the Lead Underwriter promptly of the filing of any such amendment or
supplement and of the institution by the Commission of any stop order
proceedings in respect of the Registration Statement or of any part thereof and
will use its best efforts to prevent the issuance of any such stop order and to
obtain as soon as possible its lifting, if issued.

                 (c)     If, at any time when a prospectus relating to the
Offered Securities is required to be delivered under the Act in connection with
sales by any Underwriter or dealer, any event occurs as a result of which the
Prospectus as then amended or supplemented would include an untrue statement of
a material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or if it is necessary at any time to amend the Prospectus
to comply with the Act, the Company promptly will notify the Lead Underwriter
of such event and will promptly prepare and file with the Commission, at its
own expense, an amendment or supplement which will correct such statement or
omission or an amendment which will effect such compliance.  Neither the Lead
Underwriter's consent to, nor the Underwriters' delivery of, any such amendment
or supplement shall constitute a waiver of any of the conditions set forth in
Section 5.

                 (d)     As soon as practicable, but not later than 16 months,
after the date of each Terms Agreement, the Company will make generally
available to its securityholders an earnings statement covering a period of at
least 12 months beginning after the later of (i) the effective date of the
registration statement relating to the Registered Securities, (ii) the
effective date of the most recent post-effective amendment to the Registration
Statement to become effective prior to the date of such Terms Agreement and
(iii) the date of the Company's most recent Annual Report on Form 10-K filed
with the Commission prior to the date of such Terms Agreement, which will
satisfy the provisions of Section 11(a) of the Act.

                 (e)     The Company will furnish to the Representatives copies
of the Registration Statement, including all exhibits, any related preliminary
prospectus, any related preliminary prospectus supplement, the Prospectus and
all amendments and supplements to such documents, in each case as soon as
available and in such quantities as the Lead Underwriter reasonably requests.
The Company will pay the expenses of printing and distributing to the
Underwriters all such documents.

                 (f)     The Company will arrange for the qualification of the
Offered Securities for sale and the determination of their eligibility for
investment under the laws of such jurisdictions as the Lead Underwriter
designates and will continue such qualifications in effect so long as required
for the distribution.

                 (g)     During the period of five years after the date of any
Terms Agreement, the Company will furnish to the Representatives and, upon
request, to each of the other Underwriters, if any, as soon as practicable
after the end of each fiscal year, a copy of its annual report to stockholders
for such year; and the Company will furnish to the Representatives as soon as
available, a copy of each report and any definitive proxy statement of the
Company filed with the Commission under the Securities Exchange Act of 1934 or
mailed to stockholders.

                 (h)     The Company will pay all expenses incident to the
performance of its obligations under the Terms Agreement (including the
provisions of this Agreement), for any filing fees or other expenses (including
fees and disbursements of counsel not to exceed $5,000) in connection with
qualification of the Offered Securities for sale and any determination of their
eligibility for investment under the laws of such jurisdictions as the Lead
Underwriter may designate and the printing of memoranda relating thereto, for
any fees charged by investment rating agencies for the rating of the Offered
Securities (if they are debt securities or preferred stock), for any applicable
filing fee incident to, and the reasonable fees and disbursements of counsel
for the Underwriters in connection with, the review by the National Association
of Securities Dealers, Inc. of the Registered Securities, for any travel
expenses of the Company's officers and employees and any other expenses of the
Company in connection with attending or hosting meetings with prospective
purchasers of Registered Securities and for expenses incurred in distributing
the Prospectus, any preliminary prospectuses, any preliminary prospectus
supplements or any other amendments or supplements to the Prospectus to the
Underwriters.  Except





                                       8
<PAGE>   9
as provided in the preceding sentence, the Underwriters will pay the expenses
incident to the performance of their obligations under this Agreement and will
reimburse the Company (if and to the extent incurred by the Company) for any
travel expenses of the Underwriters' representatives and any other expenses of
the Underwriters in connection with attending or hosting meetings with
prospective purchasers of the Offered Securities.

                 (i)     If the Offered Securities are debt securities or
preferred stock, the Company will not offer, sell, contract to sell, pledge or
otherwise dispose of, directly or indirectly, or file with the Commission a
registration statement under the Act relating to United States
dollar-denominated debt securities issued or guaranteed by the Company and
having a maturity of more than one year from the date of issue (if the Offered
Securities are debt securities) or any series of preferred stock issued or
guaranteed by the Company (if the Offered Securities are preferred stock), or
publicly disclose the intention to make any such offer, sale, pledge,
disposition or filing, without the prior written consent of the Lead
Underwriter for a period beginning at the time of execution of the Terms
Agreement and ending the number of days after the Closing Date specified under
"Blackout" in the Terms Agreement.

                 (j)     If the Offered Securities are Common Stock or are
convertible into Common Stock, the Company will not offer, sell, contract to
sell, pledge or otherwise dispose of, directly or indirectly, or file with the
Commission a registration statement under the Act relating to, any additional
shares of its Common Stock or securities convertible into or exchangeable or
exercisable for any shares of its Common Stock, or publicly disclose the
intention to make any such offer, sale, pledge, disposition or filing, without
the prior written consent of the Lead Underwriter for a period beginning at the
time of execution of the Terms Agreement and ending the number of days after
the Closing Date specified under "Blackout" in the Terms Agreement, except
issuances of Common Stock pursuant to the conversion or exchange of convertible
or exchangeable securities or the exercise of warrants in each case outstanding
on the date of the Terms Agreements, grants of employee stock options pursuant
to the terms of a plan in effect on the date of the Terms Agreement, issuances
of Common Stock pursuant to the exercise of such options or the exercise of any
other employee stock options outstanding on the date of the Terms Agreement or
issuances of Common Stock pursuant to registration statements on Form S-8 or
successor forms thereto.

SECTION 5.    Conditions of the Obligations of the Underwriters.

        The obligations of the several Underwriters to purchase and pay for Firm
Securities on the First Closing Date and the Optional Securities to be
purchased on each Optional Closing Date will be subject to the accuracy of the
representations and warranties on the part of the Company herein, to the
accuracy of the statements of Company officers made pursuant to the provisions
hereof, to the performance by the Company of its obligations hereunder and to
the following additional conditions precedent:

                 (a)     On or prior to the date of the Terms Agreement, the

independent public accountants who have audited financial statements that are
included in the Registration Statement and the Prospectus) confirming that they
are independent public accountants within the meaning of the Act and the
applicable published Rules and Regulations thereunder and stating to the effect
that:

                         (i)      in their opinion the financial statements and
        any financial statement schedules audited by them and included in the
        Prospectus comply as to form in all material respects with the
        applicable accounting requirements of the Act and the related published
        Rules and Regulations;

                         (ii)     they have performed the procedures specified
        by the American Institute of Certified Public Accountants for a review
        of interim financial information as described in Statement of Auditing
        Standards No. 71, Interim Financial Information, on any unaudited
        financial statements included in the Registration Statement;

                         (iii)    on the basis of the review referred to in

        responsibility for financial and accounting matters and other specified
        procedures, nothing came to their attention that caused them to believe
        that:

                         (A)      the unaudited financial statements, if any,
                 and any summary of earnings included in the Prospectus do not
                 comply as to form in all material respects with the applicable
                 accounting requirements of the Act and the related published
                 Rules and Regulations or any material modifications should be
                 made to such unaudited financial statements and summary of
                 earnings for them to be in conformity with generally accepted
                 accounting principles;

                         (B)      if any unaudited "capsule" information is
                 contained in the Prospectus, the unaudited consolidated net
                 sales, net operating income, net income and net income per
                 share amounts or other amounts constituting such "capsule"

                 corresponding amounts set forth in the unaudited consolidated
                 financial statements or were not determined on a basis
                 substantially consistent with that of the corresponding
                 amounts in the audited statements of income;

                         (C)      at the date of the latest available balance
                 sheet read by such accountants, or at a subsequent specified

                 the Terms Agreement, there was any change in the capital stock
                 or any increase in short-term indebtedness or long-term debt
                 of the Company and its consolidated subsidiaries or, at the
                 date of the latest available balance sheet read by such
                 accountants, there was any decrease in working capital or
                 stockholders' equity, as compared with amounts shown on the
                 latest balance sheet included in the Prospectus; or

                         (D)      for the period from the closing date of the

                 closing date of the latest available income statement read by
                 such accountants there were any decreases, as compared with
                 the corresponding period of the previous year and with the
                 period of corresponding length ended the date of the latest
                 income statement included in the Prospectus, in contract
                 drilling revenue, net operating income, in the total or (if
                 the Offered Securities are Common Stock or are convertible
                 into Common Stock) per share amounts of consolidated income
                 before extraordinary items or net income or (if the Offered
                 Securities are debt securities) in the ratio of earnings to
                 fixed charges or (if the Offered Securities are preferred
                 stock) in the ratio of earnings to fixed charges and preferred
                 stock dividends combined;

           except in all cases set forth in clauses (C) and (D) above for 
           changes, increases or decreases which the Prospectus discloses have 
           occurred or may occur or which are described in such letter; and

                 (iv)    they have compared specified dollar amounts (or
        percentages derived from such dollar amounts) and other financial
        information contained in the Prospectus (in each case to the extent
        that such dollar amounts, percentages and other financial information
        are derived from the general accounting records of the Company and its
        subsidiaries subject to the internal controls of the Company's
        accounting system or are derived directly from such records by analysis
        or computation) with the results obtained from inquiries, a reading of
        such general accounting records and other procedures specified in such
        letter and have found such dollar amounts, percentages and other
        financial information to be in agreement with such results, except as
        otherwise specified in such letter.

        All financial statements and schedules included in material
        incorporated by reference into the Prospectus shall be deemed included
        in the Prospectus for purposes of this subsection.

                 (b)     The Prospectus shall have been filed with the
Commission in accordance with the Rules and Regulations and Section 4(a) of
this Agreement. No stop order suspending the effectiveness of the Registration

Statement or of any part thereof shall have been issued and no proceedings for
that purpose shall have been instituted or, to the knowledge of the Company or
any Underwriter, shall be contemplated by the Commission.

                 (c)     Subsequent to the execution of the Terms Agreement,
there shall not have occurred (i) any change, or any development or event
involving a prospective change, in the condition (financial or other),
business, properties or results of operations of the Company or its
subsidiaries which, in the judgment of a majority in interest of the
Underwriters including any Representatives, is material and adverse and makes
it impractical or inadvisable to proceed with completion of the public offering
or the sale of and payment for the Offered Securities; (ii) any downgrading in
the rating of any debt securities or preferred stock of the Company by any
"nationally recognized statistical rating organization" (as defined for
purposes of Rule 436(g) under the Act), or any public announcement that any
such organization has under surveillance or review its rating of any debt
securities or preferred stock of the Company (other than an announcement with
positive implications of a possible upgrading, and no implication of a possible
downgrading, of such rating); (iii) any suspension or limitation of trading in
securities generally on the New York Stock Exchange, or any setting of minimum
prices for trading on such exchange, or any suspension of trading of any
securities of the Company on any exchange or in the over-the-counter market;
(iv) any banking moratorium declared by U.S. Federal or New York authorities;
or (v) any outbreak or escalation of major hostilities in which the United
States is involved, any declaration of war by Congress or any other substantial
national or international calamity or emergency if, in the judgment of a
majority in interest of the Underwriters including any Representatives, the
effect of any such outbreak, escalation, declaration, calamity or emergency
makes it impractical or inadvisable to proceed with completion of the public
offering or the sale of and payment for the Offered Securities.

                 (d)     The Representatives shall have received an opinion,
dated such Closing Date, of the Vice President and General Counsel of the
Company or other counsel satisfactory to the Lead Underwriter, to the effect
that:

                         (i)      The Company is a corporation duly organized,

        Delaware, and has all requisite corporate power and authority to own,
        lease and operate its properties and to carry on its business as
        described in the Prospectus; and the Company is duly qualified to
        transact business as a foreign corporation in good standing in all
        other jurisdictions in which its ownership or lease of property or the
        conduct of its business requires such qualification, except those
        jurisdictions where the failure to be so qualified would not have a
        material adverse effect on the business, operations or financial
        condition of the Company and its subsidiaries taken as a whole;

                         (ii)     If the Offered Securities delivered on such

        Contract Securities, when executed, authenticated, issued and delivered
        in the manner provided in the Indenture and sold pursuant to Delayed
        Delivery Contracts, will constitute, valid and legally binding
        obligations of the Company enforceable in accordance with their terms,
        subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
        moratorium and similar laws of general applicability relating to or
        affecting creditors' rights and to general equity principles; and the
        Offered Securities delivered on such Closing Date other than any
        Contract Securities conform, and any Contract Securities, when so
        issued and delivered and sold will conform, to the description thereof
        contained in the Prospectus;

                         (iii)    If the Offered Securities delivered on such
        Closing Date are warrants:  The Warrant Agreement has been duly
        authorized, executed and delivered by the Company; the Offered

        legally binding obligations of the Company enforceable in accordance
        with their terms, subject to bankruptcy, insolvency, fraudulent
        transfer, reorganization, moratorium and similar laws of general
        applicability relating to or affecting creditors' rights and to general
        equity principles; and the Offered Securities delivered on such Closing
        Date other than any Contract Securities conform, and any Contract
        Securities, when so issued and delivered and sold will conform, to the
        description thereof contained in the Prospectus;

        issued, delivered and sold, will conform, to the description thereof
        contained in the Prospectus; and the stockholders of the Company have
        no preemptive rights with respect to the Offered Securities;

                         (v)      If the Offered Securities delivered on such

        paid and nonassessable and conform to the description thereof contained
        in the Prospectus; and the stockholders of the Company have no
        preemptive rights with respect to the Offered Securities;

                         (vi)     If the Offered Securities delivered on such
        Closing Date are convertible or (if the Offered Securities are
        warrants) exercisable:  The Offered Securities delivered on such
        Closing Date other than any Contract Securities are, and any Contract
        Securities, when (if the Offered Securities are debt securities)
        executed, authenticated, issued and delivered in the manner provided in
        the Indenture and sold pursuant to Delayed Delivery Contracts, (if the
        Offered Securities are warrants) executed, countersigned, issued and

        Common Stock, preferred stock or debt securities of the Company, as the
        case may be, in accordance with (if they are debt securities) the
        Indenture, (if they are warrants) the Warrant Agreement or (if they are
        preferred stock) their terms; the shares of Common Stock, preferred
        stock or debt securities, initially issuable upon conversion or
        exercise of the Offered Securities have been duly authorized and (if
        the conversion or exercise securities are Common Stock or preferred
        stock) reserved for issuance upon such conversion or exercise and, if
        the conversion securities are Common Stock, such Common Stock initially
        issuable upon conversion thereof, when issued upon such conversion and
        upon receipt by the Company of the conversion price therefor, will be

                         (vii)    If the Offered Securities delivered on such
        Closing Date are Common Stock or are convertible into Common Stock:
        Except for the Loews Registration Rights Agreement, there are no
        contracts, agreements or understandings known to such counsel between
        the Company and any person granting such person the right to require
        the Company to file a registration statement under the Act with respect
        to any securities of the Company owned or to be owned by such person or
        to require the Company to include such securities in the securities
        registered pursuant to the Registration Statement or in any securities
        being registered pursuant to any other registration statement filed by
        the Company under the Act;

                         (viii)   The Company is not (A) an "investment
        company" or an entity "controlled" by an "investment company" under the
        Investment Company Act and the rules and regulations promulgated by the
        Commission thereunder or (B) a "holding company" or a "subsidiary
        company" or an "affiliate" of a holding company within the meaning of
        the Holding Company Act and the rules and regulations promulgated by
        the Commission thereunder;

                         (ix)     No consent, approval, authorization or order
        of, or filing with, any governmental agency or body or any court is
        required for the consummation of the transactions contemplated by the
        Terms Agreement (including the provisions of this Agreement) in
        connection with the issuance or sale of the Offered Securities by the
        Company, except such as have been obtained and made under the Act and,
        if the Offered Securities are debt securities, the Trust Indenture Act,
        and such as may be required under state securities laws;

                         (x)      The execution, delivery and performance of
        the Indenture (if the Offered Securities are debt securities), the
        Warrant Agreement (if the Offered Securities are warrants), the Terms
        Agreement (including the provisions of this Agreement) and, if the
        Offered Securities are debt securities, warrants or preferred stock,
        any Delayed Delivery Contracts and the issuance and sale of the Offered
        Securities and, if the Offered Securities are debt securities, warrants
        or preferred stock, compliance with the terms and provisions thereof
        will not result in a breach or violation of any of the terms and
        provisions of, or constitute a default under, any statute, any rule,
        regulation or order of any governmental agency or body or any court
        having jurisdiction over the Company or any subsidiary of the Company
        or any of their properties, or any material agreement or instrument to
        which the Company or any such subsidiary is a party or by which the
        Company or any such subsidiary is bound or to which any of the
        properties of the Company or any such subsidiary is subject, or the
        charter or by-laws of the Company or any such subsidiary, and the
        Company has full power and authority to authorize, issue and sell the
        Offered Securities as contemplated by the Terms Agreement (including
        the provisions of this Agreement).  In the case of breaches or
        violations of any terms or provisions of, or defaults under, any
        agreement or instrument of Arethusa (Off-Shore) Limited or any of its
        former subsidiaries entered into by any such entity prior to its
        acquisition by the Company, such opinion may be limited to the
        knowledge of such counsel;

                         (xi)     The Registration Statement has become
        effective under the Act, the Prospectus was filed with the Commission
        pursuant to the subparagraph of Rule 424(b) specified in such opinion
        on the date specified therein, and, to the best of the knowledge of
        such counsel, no stop order suspending the effectiveness of the
        Registration Statement or any part thereof has been issued and no
        proceedings for that purpose have been instituted or are pending or
        contemplated under the Act, and the registration statement relating to
        the Registered Securities, as of its effective date, the Registration
        Statement and the Prospectus, as of the date of the Terms Agreement,
        and any amendment or supplement thereto, as of its date, complied as to
        form in all material respects with the requirements of the Act, the
        Trust Indenture Act and the Rules and Regulations; such counsel has no
        reason to believe that such registration statement, as of its effective
        date, the Registration Statement, as of the date of the Terms Agreement
        or as of such Closing Date, or any amendment thereto, as of its date or
        as of such Closing Date, contained any untrue statement of a material
        fact or omitted to state any material fact required to be stated
        therein or necessary to make the statements therein not misleading or
        that the Prospectus, as of the date of the Terms Agreement or as of
        such Closing Date, or any amendment or supplement thereto, as of its
        date or as of such Closing Date, contained any untrue statement of a
        material fact or omitted to state any material fact necessary in order
        to make the statements therein, in the light of the





                                       13
<PAGE>   14
        circumstances under which they were made, not misleading; the
        descriptions in the Registration Statement and Prospectus of statutes,
        legal and governmental proceedings and contracts and other documents
        are accurate and fairly present the information required to be shown;
        and such counsel does not know of any legal or governmental proceedings
        required to be described in the Prospectus which are not described as
        required or of any contracts or documents of a character required to be
        described in the Registration Statement or Prospectus or to be filed as
        exhibits to the Registration Statement which are not described and
        filed as required; it being understood that such counsel need express
        no opinion as to the financial statements and related notes or the
        other financial, statistical and accounting  data contained in the
        Registration Statement or the Prospectus;

                         (xii)    The Terms Agreement (including the provisions
        of this Agreement) and, if the Offered Securities are debt securities,
        warrants or preferred stock, any Delayed Delivery Contracts have been
        duly authorized, executed and delivered by the Company;

                         (xiii)   All of the issued and outstanding shares of
        capital stock of each subsidiary of the Company designated by the
        Company on Annex I to the Terms Agreement (each, a "Subsidiary" and
        collectively, the "Subsidiaries"),  are owned, directly or indirectly,
        of record and beneficially by the Company, free and clear of all liens,
        claims, limitations on voting rights, options, security interests and
        other encumbrances and have been duly authorized, validly issued, and
        are fully paid and nonassessable, except to the extent that any such
        liens, claims, limitations, options, security interests and other
        encumbrances, individually or in the aggregate, would not have a
        material adverse effect on the business, operations or financial
        condition of the Company and its subsidiaries, taken as a whole;

                         (xiv)    Each Subsidiary is a corporation, duly
        organized, validly existing and in good standing under the laws of its
        jurisdiction of incorporation.  Each Subsidiary is duly qualified to
        transact business and is in good standing as a foreign corporation in
        each state in which such Subsidiaries are required to be qualified,
        except where the failure to be so qualified would not have a material
        adverse effect on the business, operations or financial condition of
        the Company and its subsidiaries, taken as a whole;

                         (xv)     No consent or approval of any federal
        governmental agency with respect to any federal maritime law matter is
        required in connection with performance by the Company of its
        obligations under the Terms Agreement (including the provisions of this
        Agreement) or the issuance and sale of the Offered Securities; and
        neither the issue, offer, sale or delivery by the Company of the
        Offered Securities pursuant to the Terms Agreement (including the
        provisions of this Agreement) or the execution, delivery, and
        performance by the Company and the consummation of the transactions
        contemplated thereby will violate any existing federal maritime laws,
        including, without limitation, the Shipping Act, 1916, as amended, and
        the rules and regulations of the Maritime Administration (MarAd) and
        the United States Coast Guard;  and

                         (xvi)    Except as described in the Registration
        Statement and the Prospectus, there is no litigation, proceeding or
        governmental investigation pending or, to such counsel's knowledge,
        overtly threatened against the Company or any of its subsidiaries or to
        which any of the property of the Company or any of its subsidiaries is
        subject, which, in such counsel's judgment is likely, individually or
        in the aggregate, to have a material adverse effect on the business,
        assets or financial condition of the Company and its subsidiaries,
        taken as a whole.

        In rendering such opinion, such Vice President and General Counsel or
        other counsel may rely as to the incorporation of the Company, the
        authorization, execution and delivery of the Terms Agreement and all
        other matters acceptable to the Representatives upon an opinion of
        counsel satisfactory to the Representatives, a copy of which shall be
        delivered concurrently with the opinion of the Vice President and
        General Counsel or such other counsel.

                 (e)     The Representatives shall have received from Andrews &
Kurth L.L.P., special counsel for the Underwriters (or any other counsel named
as counsel for the Underwriters in the Terms Agreement), such opinion





                                       14
<PAGE>   15
or opinions, dated such Closing Date, with respect to the incorporation of the
Company, the validity of the Offered Securities delivered on such Closing Date,
the Registration Statement, the Prospectus and other related matters as the
Representatives may require, and the Company shall have furnished to such
counsel such documents as they request for the purpose of enabling them to pass
upon such matters.

                 (f)     The Representatives shall have received a certificate,
dated such Closing Date, of the President, any Senior Vice President, the
Treasurer or any Vice President and a principal financial or accounting officer
of the Company in which such officers, to the best of their knowledge after
reasonable investigation, shall state that the representations and warranties
of the Company in this Agreement are true and correct, that the Company has
complied with all agreements and satisfied all conditions on its part to be
performed or satisfied hereunder at or prior to such Closing Date, that no stop
order suspending the effectiveness of the Registration Statement or of any part
thereof has been issued and no proceedings for that purpose have been
instituted or are contemplated by the Commission and that, subsequent to the
date of the most recent financial statements in the Prospectus, there has been
no material adverse change, nor any development or event involving a
prospective material adverse change, in the condition (financial or other),
business, properties or results of operations of the Company and its
subsidiaries taken as a whole except as set forth in or contemplated by the
Prospectus or as described in such certificate.

                 (g)     The Representatives shall have received a letter,
dated such Closing Date, of Deloitte & Touche LLP (and any other firm of
independent public accountants who have audited financial statements that are
included in the Registration Statement and the Prospectus) which meets the
requirements of subsection (a) of this Section, except that the specified date
referred to in such subsection will be a date not more than three business days
prior to such Closing Date for the purposes of this subsection.

        The Company will furnish the Representatives with such conformed copies
of such opinions, certificates, letters and documents as the Representatives
reasonably request.  The Lead Underwriter may in its sole discretion waive on
behalf of the Underwriters compliance with any conditions to the obligations of
the Underwriters under this Agreement and the Terms Agreement.

SECTION 6.    Indemnification and Contribution.

                 (a)     The Company will indemnify and hold harmless each
Underwriter against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in the Registration
Statement, the Prospectus, or any amendment or supplement thereto, or any
related preliminary prospectus or preliminary prospectus supplement, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse each Underwriter for any legal or
other expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such loss, claim, damage, liability or action as
such expenses are incurred; provided, however, that the Company will not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement in or omission or alleged omission from any of such documents in
reliance upon and in conformity with written information furnished to the
Company by any Underwriter through the Representatives, if any, specifically
for use therein, it being understood and agreed that the only such information
furnished by any Underwriter consists of the information described as such in
the Terms Agreement, provided that this indemnity agreement with respect to any
preliminary prospectus shall not inure to the benefit of any Underwriter from
whom the person asserting any such losses, claims, damages or liabilities
purchased Offered Securities, or any person controlling such Underwriter, if
the Company shall have sustained the burden of proving that a copy of the
Prospectus (as then amended or supplemented if the Company shall have furnished
any such amendments or supplements thereto) was not sent or given by or on
behalf of the Underwriter to such person if such is required by law at or prior
to the written confirmation of the sale of such Offered Securities to such
person and if the Prospectus (as so amended or supplemented) would have
corrected any untrue statement or omission, or alleged untrue statement or
omission, giving





                                       15
<PAGE>   16
rise to such loss, claim, damage or liability (provided the Company has
delivered the Prospectus to the several Underwriters in requisite quantity on a
timely basis to permit such delivery or sending).

                 (b)     Each Underwriter will severally and not jointly
indemnify and hold harmless the Company against any losses, claims, damages or
liabilities to which the Company may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in the Registration
Statement, the Prospectus, or any amendment or supplement thereto, or any
related preliminary prospectus or preliminary prospectus supplement, or arise
out of or are based upon the omission or the alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through the
Representatives, if any, specifically for use therein, and will reimburse any
legal or other expenses reasonably incurred by the Company in connection with
investigating or defending any such loss, claim, damage, liability or action as
such expenses are incurred, it being understood and agreed that the only such
information furnished by any Underwriter consists of the information described
as such in the Terms Agreement.

                 (c)     Promptly after receipt by an indemnified party under
this Section of notice of the commencement of any action, such indemnified
party will, if a claim in respect thereof is to be made against the
indemnifying party under subsection (a) or (b) above, notify the indemnifying
party of the commencement thereof; but the omission so to notify the
indemnifying party will not relieve it from any liability which it may have to
any indemnified party otherwise than under subsection (a) or (b) above, except
to the extent a defense or counterclaim has been foreclosed.  In case any such
action is brought against any indemnified party and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (who shall not,
except with the consent of the indemnified party, be counsel to the
indemnifying party), and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such indemnified party under this
Section for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened action in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party unless such settlement includes an unconditional release of such
indemnified party from all liability on any claims that are the subject matter
of such action.

                 (d)     If the indemnification provided for in this Section is
unavailable or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities referred to in subsection (a) or (b) above (i)
in such proportion as is appropriate to reflect the relative benefits received
by the Company on the one hand and the Underwriters on the other from the
offering of the Offered Securities or (ii) if the allocation provided by clause
(i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company on the one hand and the
Underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities as well as any other
relevant equitable considerations. The relative benefits received by the
Company on the one hand and the Underwriters on the other shall be deemed to be
in the same proportion as the total net proceeds from the offering (before
deducting expenses) received by the Company bear to the total underwriting
discounts and commissions received by the Underwriters. The relative fault
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the Company or the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such untrue statement or omission. The
amount paid by an indemnified party as a result of the losses, claims, damages
or liabilities referred to in the first sentence of this subsection (d) shall
be deemed to include any legal or other expenses reasonably incurred by such
indemnified party





                                       16
<PAGE>   17
in connection with investigating or defending any action or claim which is the
subject of this subsection (d).  Notwithstanding the provisions of this
subsection (d), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Offered Securities
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations in this subsection (d) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

                 (e)     The obligations of the Company under this Section
shall be in addition to any liability which the Company may otherwise have and
shall extend, upon the same terms and conditions, to each person, if any, who
controls any Underwriter within the meaning of the Act; and the obligations of
the Underwriters under this Section shall be in addition to any liability which
the respective Underwriters may otherwise have and shall extend, upon the same
terms and conditions, to each director of the Company, to each officer of the
Company who has signed the Registration Statement and to each person, if any,
who controls the Company within the meaning of the Act.

SECTION 7.    Default of Underwriters.

        If any Underwriter or Underwriters default in their obligations to
purchase Offered Securities on the First or any Optional Closing Date under the
Terms Agreement and the aggregate principal amount (if debt securities), number
(if warrants) or number of shares (if preferred stock or Common Stock) of
Offered Securities that such defaulting Underwriter or Underwriters agreed but
failed to purchase does not exceed 10% of the total principal amount (if debt
securities), number (if warrants) or number of shares (if preferred stock or
Common Stock) of Offered Securities, the Lead Underwriter may make arrangements
satisfactory to the Company for the purchase of such Offered Securities by
other persons, including any of the Underwriters, but if no such arrangements
are made by such Closing Date, the non- defaulting Underwriters shall be
obligated severally, in proportion to their respective commitments under the
Terms Agreement (including the provisions of this Agreement), to purchase the
Offered Securities that such defaulting Underwriters agreed but failed to
purchase on such Closing Date.  If any Underwriter or Underwriters so default
and the aggregate principal amount (if debt securities), number (if warrants)
or number of shares (if preferred stock or Common Stock) of Offered Securities
with respect to which such default or defaults occur exceeds 10% of the total
principal amount (if debt securities), number (if warrants) or number of shares
(if preferred stock or Common Stock) of Offered Securities that the
Underwriters are obligated to purchase on such Closing Date and arrangements
satisfactory to the Lead Underwriter and the Company for the purchase of such
Offered Securities by other persons are not made within 36 hours after such
default, the Terms Agreement will terminate without liability on the part of
any non-defaulting Underwriter or the Company, except as provided in Section 8
(provided that if such default occurs with respect to Optional Securities after
the First Closing Date, such Terms Agreement will not terminate as to the Firm
Securities or any Optional Securities purchased prior to such termination).  As
used in this Agreement, the term "Underwriter" includes any person substituted
for an Underwriter under this Section.  Nothing herein will relieve a
defaulting Underwriter from liability for its default.  If the Offered
Securities are debt securities,warrants or preferred stock, the respective
commitments of the several Underwriters for the purposes of this Section shall
be determined without regard to reduction in the respective Underwriters'
obligations to purchase the principal amounts (if debt securities), number (if
warrants) or numbers of shares (if preferred stock) of the Offered Securities
set forth opposite their names in the Terms Agreement as a result of Delayed
Delivery Contracts entered into by the Company.

SECTION 8.    Survival of Certain Representations and Obligations.

        The respective indemnities, agreements, representations, warranties and
other statements of the Company or its officers and of the several Underwriters
set forth in or made pursuant to the Terms Agreement (including the provisions
of this Agreement) will remain in full force and effect, regardless of any
investigation, or statement as to the results thereof, made by or on behalf of
any Underwriter, the Company or any of their respective representatives,
officers or directors or any controlling person, and will survive delivery of
and payment for the Offered Securities. If the Terms Agreement is terminated
pursuant to Section 7 or if for any reason the purchase of the Offered
Securities by





                                       17
<PAGE>   18
the Underwriters is not consummated, the Company shall remain responsible for
the expenses to be paid or reimbursed by it pursuant to Section 4 and the
respective obligations of the Company and the Underwriters pursuant to Section
6 shall remain in effect, and if any Offered Securities have been purchased
hereunder, the representations in Section 2 and all obligations under Section 4
shall also remain in effect.  If the purchase of the Offered Securities by the
Underwriters is not consummated for any reason other than solely because of the
termination of the Terms Agreement pursuant to Section 7 or the occurrence of
any event specified in clause (iii), (iv) or (v) of Section 5(c), the Company
will reimburse the Underwriters for all out-of-pocket expenses (including fees
and disbursements of counsel) reasonably incurred by them in connection with
the offering of the Offered Securities.

SECTION 9.    Notices.

        All communications hereunder will be in writing and, if sent to the
Underwriters, will be mailed, delivered or telecopied and confirmed to them at
their address furnished to the Company in writing for the purpose of
communications hereunder or, if sent to the Company, will be mailed, delivered
or telegraphed and confirmed to it at 15415 Katy Freeway, Houston, Texas
77094, Attention:  Richard L. Lionberger, telecopy (281) 647-2223.

SECTION 10.   Successors.

        The Terms Agreement (including the provisions of this Agreement) will
inure to the benefit of and be binding upon the Company and such Underwriters
as are identified in the Terms Agreement and their respective successors and
the officers and directors and controlling persons referred to in Section 6,
and no other person will have any right or obligation hereunder.

SECTION 11.   Representation of Underwriters.

        Any Representatives will act for the several Underwriters in connection
with the financing described in the Terms Agreement, and any action under such
Terms Agreement (including the provisions of this Agreement) taken by the
Representatives jointly or by the Lead Underwriter will be binding upon all the
Underwriters.

SECTION 12.   Counterparts.

        The Terms Agreement may be executed in any number of counterparts, each
of which shall be deemed to be an original, but all such counterparts shall
together constitute one and the same Agreement.

SECTION 13.   APPLICABLE LAW.

        THIS AGREEMENT AND THE TERMS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD
TO PRINCIPLES OF CONFLICTS OF LAWS.

        The Company hereby submits to the non-exclusive jurisdiction of the
Federal and state courts in the Borough of Manhattan in The City of New York in
any suit or proceeding arising out of or relating to the Terms Agreement
(including the provisions of this Agreement) or the transactions contemplated
thereby.

                               ANNOUNCES EARNINGS

        Houston, Texas, April 14, 1997 -- Diamond Offshore Drilling, Inc.
(NYSE:DO) today reported net income of $56.2 million, or $0.79 per share and
common equivalent share, on revenues of $204.7 million for the quarter ended

revenues of $106.9 million for the quarter ended March 31, 1996.

        "Our quarterly earnings reflect the positive dayrate environment,"
commented Robert E. Rose, President and Chief Executive Officer of Diamond
Offshore, "as well as revenues from deliveries of two of our fourth generation

the Ocean Star, which is currently drilling in approximately 4,300 feet of
water, as well as a full quarter for the Ocean Quest, which is currently
drilling in approximately 3,200 feet of water." Both of these fourth generation
capable rigs are operating under three-year contracts in the Gulf of Mexico.

        Separately, Diamond Offshore's Ocean Crusader has been awarded the 1996
Safety Award for Excellence ("SAFE" Award) by the Houma District of the U.S.
Department of the Interior, Minerals Management Service (MMS). The award
recognizes companies for their record of performance in safety and
environmental protection. This is the fifth consecutive district SAFE Award
presented to the Company since 1992 when the Company implemented its quality
program, the Global Excellence Management System. Diamond Offshore was the
recipient of the 1993 and 1994 MMS National SAFE Award.

        Diamond Offshore is a leader in deep water drilling. The Company owns
46 offshore major mobile drilling rigs, including 30 semisubmersibles, 15
jack-ups and one drillship. The fleet operates in the waters of six of the

FOR IMMEDIATE RELEASE                                     CONTACT: Caren Steffes
Monday, April 14, 1997                                           (281) 492-5393

                        DIAMOND OFFSHORE DRILLING, INC.
                  AGREEMENT TO A ACQUIRE ACCOMMODATION VESSEL

Diamond Offshore Drilling, Inc. (NYSE:DO) announced today that it has reached
an agreement in principle to acquire the Polyconfidence, a semisubmersible
accommodation vessel currently working in the U.K. sector of the North Sea.
Diamond Offshore's cost to acquire the vessel is expected to be approximately
$81 million payable in cash.

The Polyconfidence was constructed in 1987 and has Class III dynamic
positioning capabilities. The Company is in discussions with several oil
companies regarding conversion of the Polyconfidence to a semisubmersible
drilling unit with fourth or fifth-generation capabilities. Such a conversion
would be dependent upon the receipt of a term contract commitment at favorable
dayrates. Although the extent of the conversion would be dependent upon the
particular demands of the customer, the Company's preliminary estimate of
conversion cost is approximately $160 - $175 million. The Polyconfidence would
begin its conversion at the conclusion of its present accommodation unit
contract, which is estimated to occur no later than March 1998. Prior to
expiration of this contract, the Company will receive approximately $15,000 per
day under a bareboat charter of the vessel.

The Company expects to finance the conversion of the Polyconfidence through the
use of cash on hand or internally generated funds. The vessel purchase is
expected to be financed through a public offering of approximately 1.25 million
shares of the Company's Common Stock.

Diamond Offshore is a leader in deep water drilling. The Company owns 46 mobile
offshore drilling rigs, including 30 semisubmersibles, 15 jack-ups and one
drillship. The fleet currently operates in the waters of six of the world's
seven continents.
