ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Registrant has authority under Section 83 of the Business Corporation
Law of the State of Louisiana to indemnify its officers, directors, employees
and agents to the extent provided in such statute. Article VI of the
Registrant's Bylaws provides for indemnification of the Registrant's officers,
directors, employees and agents to the fullest extent permitted by the Business
Corporation Law of the State of Louisiana.
 
     The Registrant has entered into Indemnification Agreements with each of its
directors. The Indemnification Agreements provide that, to the extent the
Registrant maintains directors' and officers' liability insurance policies, each
director will be named as an insured under such policies. The Indemnification
Agreements also provide that the Registrant will indemnify each director against
losses and expenses as a result of a claim or claims made against him for any
act, failure to act or neglect or breach of duty, including any error,
misstatement or misleading statement committed, suffered, permitted or
acquiesced in by the director, or any of the foregoing alleged by any claimant,
or any claim against the director or executive officer solely by reason of him
being a director or officer of the Registrant, subject to certain exclusions.
The Indemnification Agreements also provide certain procedures regarding the
right to indemnification and for the advancement of expenses.
 
     Section 24 of the Business Corporation Law of the State of Louisiana
permits the limitation of directors' personal liability to the corporation or
its shareholders for monetary damages for breach of fiduciary duties as a
director except in certain situations including the breach of a director's duty
of loyalty or acts or omissions not made in good faith. Article VI of the
Registrant's Articles of Incorporation includes such a limitation and limits
directors' personal liability to the extent permitted by Section 24.
 
     Article VI of the Registrant's Bylaws provides that the Registrant may
maintain insurance, at its expense, to protect itself and any of its directors,
officers, employees or agents or any person serving at the request of the
Registrant as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against any expense,
liability or loss, whether or not the Registrant would have the power to
indemnify such person against such expense, liability or loss under the
Louisiana Business Corporation Law.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Securities Act") may be permitted to directors, officers or
persons controlling the registrant pursuant to the foregoing provisions, the
Registrant has been informed that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is therefore unenforceable.

ITEM 17. UNDERTAKINGS
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described in Item 15 above, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
     The Registrant hereby undertakes that, for purposes of determining
liability under the Securities Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act
of 1934, as amended (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934, as amended) that is incorporated by reference in the Registration
Statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
              Act, the information omitted from the form of prospectus filed as
              part of this registration statement in reliance upon Rule 430A and
              contained in a form of prospectus filed by the Registrant pursuant
              to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall
              be deemed to be part of this Registration Statement as of the time
              it was declared effective.
 
          (2) For purposes of determining any liability under the Securities
              Act, each post-effective amendment that contains a form of
              prospectus shall be deemed to be a new registration statement
              relating to the securities offered therein, and the offering of
              such securities at that time shall be deemed to be the initial
              bona fide offering thereof.

         1.       Representations and Warranties.

                  (a) The Company represents and warrants to, and agrees with,
each U.S. Underwriter as set forth below in this Section 1. Certain terms used
in this Section 1 are defined in paragraph (iv) hereof.

                           (i) The Company meets the requirements for use of
         Form S-3 under the Securities Act of 1933, as amended (the "Act"), and
         has filed with the Securities and Exchange Commission (the
         "Commission") a registration statement (file number 333-18773) on Form
         S-3, including a related preliminary prospectus, for the registration
         under the Act of the offering and sale of the Securities. The Company
         may have filed one or more amendments thereto, including the related
         preliminary prospectuses, each of which has previously been furnished
         to you. The Company will next file with the Commission either (A) prior
         to effectiveness of such registration statement, a further amendment to
         such registration statement (including the form of final prospectuses)
         or (B) after effectiveness of such registration statement, final
         prospectuses in accordance with Rules 430A and 424(b)(1) or (4). In the
         case of clause (B), the Company has included in such registration
         statement, as amended at the Effective Date, all information (other
         than Rule 430A Information) required by the Act and the rules
         thereunder to be included in the Prospectuses with respect to the
         Securities and the offering thereof. As filed, such amendment and form
         of final prospectuses, or such final prospectuses, shall contain all
         Rule 430A Information, together with all other such required
         information,


                                       -2-

         with respect to the Securities and the offering thereof and, except to
         the extent the U.S. Representatives shall agree in writing to a
         modification, shall be in all substantive respects in the form
         furnished to you prior to the Execution Time or, to the extent not
         completed at the Execution Time, shall contain only such specific
         additional information and other changes (beyond that contained in the
         latest U.S. Preliminary Prospectus) as the Company has advised you,
         prior to the Execution Time, will be included or made therein.

                           (ii) It is understood that two forms of prospectuses
         are to be used in connection with the offering and sale of the
         Securities: one form of prospectus relating to the U.S. Securities,
         which are to be offered and sold to United States and Canadian Persons,
         and one form of prospectus relating to the International Securities,
         which are to be offered and sold to persons other than United States
         and Canadian Persons. Such form of prospectus relating to the U.S.
         Securities as first filed pursuant to Rule 424(b) or, if no filing
         pursuant to Rule 424(b) is made, such form of prospectus included in
         the Registration Statement at the Effective Date, is hereinafter called
         the "U.S. Prospectus;" such form of prospectus relating to the
         International Securities as first filed pursuant to Rule 424(b) or, if
         no filing pursuant to Rule 424(b) is made, such form of prospectus
         included in the Registration Statement at the Effective Date, is
         hereinafter called the "International Prospectus;" and the U.S.
         Prospectus and the International Prospectus are hereinafter
         collectively called the "Prospectuses."

                           (iii) On the Effective Date, the Registration
         Statement did or will, and when the Prospectuses are first filed (if
         required) in accordance with Rule 424(b) and on the Closing Date, each
         Prospectus (and any supplements thereto) will, comply in all material
         respects with the applicable requirements of the Act and the Securities
         Exchange Act of 1934, as amended (the "Exchange Act"), and the
         respective rules thereunder; on the Effective Date, the Registration
         Statement did not or will not contain any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary in order to make the statements therein, in light
         of the circumstances under which they were made, not misleading; and,
         on the Effective Date, each Prospectus, if not filed pursuant to Rule
         424(b), did not or will not, and on the date of any filing pursuant to
         Rule 424(b) and on the Closing Date, each Prospectus (together with any
         supplement thereto) will not, include any untrue statement of a
         material fact or omit to state a material fact necessary in order to
         make the statements therein, in light of the circumstances under which
         they were made, not misleading; provided, however, that the Company
         makes no representations or warranties as to the information contained
         in or omitted from the Registration Statement or the Prospectuses (or
         any supplement thereto) in reliance upon and in conformity with
         information furnished in writing to the Company by or on behalf of any
         U.S. Underwriter through the U.S. Representatives specifically for
         inclusion in the Registration Statement or the Prospectuses (or any
         supplement thereto).

         audited consolidated financial statements of the Company are filed as
         part of the Registration Statement and the Prospectuses, are
         independent public accountants within the meaning of the Act and the
         applicable rules and regulations thereunder.


                           (viii) The consolidated financial statements and
         schedules of the Company included in the Registration Statement and the
         Prospectuses, taken together, present fairly the consolidated financial

         respective dates and the consolidated results of operations, cash flows
         and changes in shareholders' equity of the Company for the respective

         except as set forth therein. The pro forma financial statements and pro
         forma financial information

         included in the Registration Statement and the Prospectuses (A) present
         fairly in all material respects the information shown therein, (B) have
         been prepared in accordance with the applicable requirements of Rule
         11-02 of Regulation S-X promulgated under the Act, (C) have been
         properly computed on the basis described therein, and (D) are based on
         assumptions that are reasonable.

                           (ix) Except as contemplated in the Prospectuses,
         subsequent to the respective dates for which information is given in
         the Registration Statement and the Prospectuses, neither the Company
         nor any of its Subsidiaries has incurred any material liabilities or
         material obligations, direct or contingent, or entered into any
         material transactions, in each case not in the ordinary course of
         business, and there has not been any material change in the capital
         stock or long-term debt of the Company or any of its Subsidiaries, any

         dividend on the capital stock of the Company or any of its Subsidiaries

         other), business, properties, assets, prospects or results of
         operations of the Company and its subsidiaries taken as a whole.

                           (x) Neither the issuance and sale of the Securities,
         the execution, delivery or performance of this Agreement by the Company
         nor the consummation of the transactions herein contemplated and the
         fulfillment of the terms hereof by the Company (A) requires the
         consent, approval, authorization, registration or qualification of or
         with any governmental authority or order of any court, except such as
         have been obtained, such as may be required under state securities or
         Blue Sky laws, the laws of jurisdictions outside the United States or
         the by-laws of the National Association of Securities Dealers, Inc.
         (the "NASD"), and, if the Registration Statement is not effective under
         the Act as of the Execution Time, such as may be required (and shall be
         obtained as provided in this Agreement) under the Act, or (B) conflicts
         with or results in a breach or violation of any of the terms and
         conditions of, or constitutes a default under, any indenture, mortgage,
         deed of trust, lease, license or other agreement or instrument to which
         the Company or any of its Subsidiaries is a party or by which the
         Company or any of its Subsidiaries or any of their respective
         properties are bound, or the charter or by-laws of the Company or any
         of its Subsidiaries, or any statute, rule or regulation applicable to
         the Company or any of its Subsidiaries or any judgment, decree, or
         order of any court or other governmental authority or arbitrator
         applicable to the Company or any of its Subsidiaries, which breach or
         default could have a material adverse effect on the condition
         (financial or other), business, properties, assets or results of
         operations of the Company and its subsidiaries taken as a whole.

                           (xi) Except as set forth in the Prospectuses, there
         is not now pending or, to the best knowledge of the Company,
         threatened, any action, suit or proceeding to which the Company or any
         of its subsidiaries is a party before or by any court or governmental
         agency or body (including without limitation proceedings of the
         Commission pursuant to Section 8(b) of the Act or by any Blue Sky
         authority) that is reasonably likely to (A) result in any material
         adverse change in the condition (financial or other), business,
         properties, assets or results of operations of the Company and its
         subsidiaries taken as a whole, or (B) materially and adversely affect
         the ability of the Company to carry out its obligations hereunder.

                           (xii) Each of the Company and its Subsidiaries has
         been duly incorporated and is validly existing as a corporation or
         other business entity, as the case may be, in good standing under the
         laws of the jurisdiction in which it was chartered or organized, with
         full corporate power and authority to own its properties and conduct
         its business as described in the Registration Statement and the
         Prospectuses. Each of the Company and its Subsidiaries is duly
         qualified to do business and is in good standing as a foreign
         corporation under the laws of each jurisdiction in which it owns or
         leases properties or conducts business and in which the failure,
         individually or in the aggregate, to be so qualified could have a
         material adverse effect on the condition (financial or other),
         business, properties, assets or results of operations of the Company
         and its Subsidiaries taken as a whole. Each of the Company and its
         subsidiaries possesses all consents, certificates, approvals,
         authorizations, orders, registrations, qualifications, licenses and
         permits of and from all state and federal public, regulatory or
         governmental agencies and bodies necessary to the ownership, leasing
         and operation of its properties and the conduct of its business as
         described in the Registration Statement and the Prospectuses, except
         where the failure to obtain and maintain any such consent, certificate,
         approval, authorization, order, registration, qualification, license or
         permit would not have a material adverse effect on the condition
         (financial or other), business, properties, assets or results of
         operations of the Company and its subsidiaries taken as a whole, and no
         such consent, certificate, approval, authorization, order,
         registration, qualification, license or permit contains any restriction
         that would prevent the Company or any of its Subsidiaries from owning
         and operating its properties and conducting its business as described
         in the Registration Statement and the Prospectuses. Neither the Company
         nor any such Subsidiary has received any notice of proceedings relating
         to the revocation or modification of any such consent, certificate,
         approval, authorization, order, registration, qualification, license or
         permit that, singly or in the aggregate, if the subject of an
         unfavorable decision, ruling or finding, would result in a material
         adverse change in the condition (financial or other), business,
         properties, assets or results of operations of the Company and its
         subsidiaries taken as a whole.

                           (xiii) All outstanding capital stock of each of the
         Subsidiaries has been duly authorized, is validly issued, fully paid
         and nonassessable and is owned


                                       -7-


<PAGE>   8



         by the Company, either directly or indirectly through wholly-owned
         subsidiaries (except in the case of CCC, of which the Company only owns
         49% of the outstanding capital stock), free and clear of any security
         interests, claims, liens or encumbrances, except for restrictions
         imposed by the Act or applicable state securities laws or, in the case
         of CCC, the agreement entered into by and among the Shareholders of CCC
         (the "CCC Shareholders Agreement"). None of the outstanding capital
         stock of any of the Subsidiaries has been issued in violation of any
         preemptive rights or rights of first refusal. No options, warrants or
         other rights to purchase or otherwise acquire any authorized but
         unissued shares of capital stock of any of the Subsidiaries or any
         security convertible into shares of such capital stock are now
         outstanding and no shares of capital stock of any of the Subsidiaries
         have been reserved for issuance. Except for the shares of capital stock
         of each of the subsidiaries owned by the Company or one or more
         subsidiaries of the Company, neither the Company nor any subsidiary of
         the Company owns any shares of stock or any other equity securities of
         any corporation or has any equity interest in any form of partnership,
         association or other entity (except as disclosed on Schedule II
         hereto).

                           (xiv) The Company's authorized and outstanding equity
         capitalization is as set forth under the heading "Capitalization" in
         the Prospectuses, as of the date set forth therein, and the outstanding
         shares of Common Stock have been duly authorized and validly issued and
         are fully paid and nonassessable. The Securities have been duly
         authorized and, when issued and delivered to and paid for by the U.S.
         Underwriters pursuant to this Agreement and the International
         Underwriters pursuant to the International Underwriting Agreement will
         be validly issued, fully paid and nonassessable. No further approval or
         authority of the shareholders or the directors of the Company or,
         except in the case of the Act and Blue Sky laws of the various states
         and the by-laws of the NASD, of any U.S. governmental authority or
         agency are required for the issuance and sale of the Securities as
         contemplated herein or as contemplated in the International
         Underwriting Agreement. Except as set forth in the Prospectuses, no
         options, warrants, preemptive rights or other rights to purchase or
         otherwise acquire any authorized but unissued shares of Common Stock of
         the Company or any security convertible into shares of Common Stock of
         the Company are now outstanding and no shares of Common Stock have been
         reserved for issuance. No shares of Common Stock are required pursuant
         to any contract or other right to be included in the Registration
         Statement, other than the shares held by William J. Dore included
         therein.

                           (xv) Neither the Company nor any of its Subsidiaries
         (nor the manner in which any of them conducts its business or proposes
         to conduct its business) is in violation of any law, ordinance or

         United States Coast Guard, the Environmental Protection Agency and any
         other environmental authority, except those violations that would not
         have a material adverse effect on the condition (financial or other),
         business, properties, assets or results of operations of the Company
         and its subsidiaries taken as a whole.

                           (xvi) Neither the Company nor any of its Subsidiaries
         is in breach of any term of its respective charter, by-laws or other
         organizational documents; and no default exists (and no event has
         occurred that with notice or lapse of time, or both, would constitute a
         default) in the due performance and observance of any term, covenant or
         condition of any indenture, mortgage, deed of trust, lease, note, bank
         loan or credit agreement, license or any other agreement or instrument,
         including without limitation any U.S. government ship financing bonds,
         to which the Company or any of its Subsidiaries is a party or by which
         the Company or any of its Subsidiaries or any of their respective
         properties may be bound, which breach or default would have a material
         adverse effect on the condition (financial or other), business,
         properties, assets or results of operations of the Company and it
         subsidiaries taken as a whole.

                           (xvii) The Company and its Subsidiaries have good and
         defensible title to all of the real property, vessels and assets
         described as owned by each of them in the Prospectuses, in each case
         free and clear of any security interests, liens, encumbrances,
         equities, claims and other defects, except (A) such as are disclosed in
         the Prospectuses or do not materially and adversely affect the value of
         such property, and (B) such as do not interfere in any material respect
         with the use made or proposed to be made of such property by the
         Company or such Subsidiary; and any real property and buildings held
         under any lease by the Company or its Subsidiaries are held under
         leases that are valid, existing and in full force and effect, except
         where the failure to be valid, existing and in full force and effect
         would not have a material adverse effect on the condition (financial or
         other), business, properties, assets or results of operations of the
         Company and its subsidiaries taken as a whole.

                           (xviii) The Company has in effect with insurers of
         recognized financial responsibility insurance against such losses and
         risks and in amounts that the Company reasonably believes are adequate
         in light of the business conducted by the Company and its subsidiaries
         and the properties owned by them; and the Company has no reason to
         believe, based on the financial position and operations of the Company
         and its subsidiaries, that the Company will not be able to renew its
         existing insurance coverage as and when such coverage expires or to
         obtain similar coverage from similar insurers as may be necessary to
         continue their business at a cost that would not have a material
         adverse effect on the condition (financial or other), business,
         properties, assets or results of operations of the Company and its
         subsidiaries taken as a whole.

                           (xix) The Company and its subsidiaries own or have
         the right to use all patents, patent applications, trademarks, service
         marks, trade names, licenses, sublicenses and rights thereof that are
         described in the Prospectuses or are necessary for the conduct of their
         respective businesses in the manner in which it is being conducted,
         except for those the absence of which would not in the aggregate have a
         material adverse effect on the business and operations of the Company
         and its subsidiaries taken as a whole, and no default exists (and no
         event has occurred that with notice or lapse of time, or both, would
         constitute a default) in the due performance of and observance of, and
         no event has occurred (including in connection with the offering of the
         Securities contemplated by this Agreement) that would effect the
         Company's or any such subsidiary's right to use the equipment and
         technology currently used by the Company or any such subsidiary under
         any term, covenant or condition of any license or sublicense to which
         the Company or any such subsidiary is a party except where the loss of
         such right or rights would not have a material adverse effect on the
         results of operations of the Company and its subsidiaries, taken as a
         whole.

                           (xx) No labor disturbance, strike or slowdown exists
         with any employees of the Company or any of its Subsidiaries or, to the
         best knowledge of the Company, is threatened that in any such case is
         reasonably likely to have a material adverse effect on the condition
         (financial or other), business, properties, assets or results of
         operations of the Company and its subsidiaries taken as a whole.

                           (xxi) None of the Company, its subsidiaries, or any
         officer, director or affiliate of them has taken or will take, directly
         or indirectly, any action designed to cause or result in, or that has
         constituted or might reasonably be expected to cause or result in, the
         stabilization or manipulation of the price of any securities of the
         Company to facilitate the sale or resale of the Securities.

                           (xxii) The Company and its Subsidiaries have filed
         all federal, state and foreign income and franchise tax returns
         required to be filed and have paid all taxes shown thereon to be due,
         except for those taxes that are being contested in good faith or with
         respect to which an extension has been granted; and there is no tax
         deficiency that has been, or, to the best knowledge of the Company,
         might be, asserted against the Company, any of its Subsidiaries or any
         of their respective properties or assets that would have a material
         adverse effect on the condition (financial or other), business,
         properties, assets or results of operations of the Company and its
         subsidiaries taken as a whole.

                           (xxiii) The Company is not an "investment company"
         within the meaning of the Investment Company Act of 1940, as amended,
         and this transaction will not cause the Company to become an investment
         company subject to registration under such Act.

                  (b)      The Selling Shareholder represents and warrants to,
and agrees with, each U.S. Underwriter that:

                           (i) The Selling Shareholder is the sole and lawful
         owner of the Securities to be sold by the Selling Shareholder hereunder
         and, upon sale and delivery of, and payment for, such Securities, as
         provided herein, the Selling Shareholder will convey to the U.S.
         Underwriters good and marketable title to such Securities, free and
         clear of all liens, encumbrances, equities and claims whatsoever.

                           (ii) The Selling Shareholder has no reason to believe
         that the representations and warranties of the Company contained in
         this Section 1 are not true and correct, is familiar with the
         Registration Statement and has no knowledge that the Registration
         Statement or the Prospectuses or any supplement thereto contains any
         untrue statement of a material fact or omits to state any material fact
         required to be stated therein or necessary in order to make the
         statements therein, in light of the circumstances under which they were
         made, not misleading; provided, however, that the Selling Shareholder
         makes no representations or warranties as to the information contained
         in or omitted from the Registration Statement or the Prospectuses (or
         any supplement thereto) in reliance upon and in conformity with
         information furnished in writing to the Company by or on behalf of any
         U.S. Underwriter through the U.S. Representatives specifically for
         inclusion in the Registration Statement or the Prospectuses (or any
         supplement thereto); and the sale of the Securities by the Selling
         Shareholder pursuant hereto is not prompted by any material adverse
         information concerning the Company or any Subsidiary that is not set
         forth in the Prospectuses or any supplement thereto.

                           (iii) The Selling Shareholder has not taken and will
         not take, directly or indirectly, any action designed to cause or
         result in, or that has constituted or might reasonably be expected to
         cause or result in, stabilization or manipulation of the price of any
         securities of the Company to facilitate the sale or resale of the
         Securities.

                           (iv) This Agreement and the International
         Underwriting Agreement have been duly executed and delivered by the
         Selling Shareholder.

                           (v) Certificates in negotiable form for the
         Securities of the Selling Shareholder to be sold hereunder have been
         placed in custody, for delivery pursuant to the terms of this
         Agreement, under a Custody Agreement and related Power-of-Attorney
         executed and delivered by the Selling Shareholder, in the form
         heretofore furnished you (the "Custody Agreement" and the
         "Power-of-Attorney," respectively) with Michael J. Pollock, as
         Custodian and Attorney-in-Fact (the "Custodian"); the Securities
         represented by the certificates so held in custody for the Selling
         Shareholder are subject to the interests hereunder of the U.S.
         Underwriters


                                      -11-

         and the Company; the arrangements for custody and delivery of such
         certificates, made by the Selling Shareholder hereunder and under the
         Custody Agreement, are not subject to termination by any act of the
         Selling Shareholder, or by operation of law, whether by the death or
         incapacity of the Selling Shareholder or the occurrence of any other
         event; and if any such death, incapacity or any other event shall occur
         before delivery of such Securities hereunder, certificates for the
         Securities will be delivered by the Custodian in accordance with the
         terms and conditions of this Agreement and the Custody Agreement as if
         such death, incapacity or other event had not occurred, regardless of
         whether or not the Custodian shall have received notice of such death,
         incapacity or other event.

                           (vi) No consent, approval, authorization,
         registration or qualification of or with any governmental authority or
         order of any court is required for the consummation by the Selling
         Shareholder of the transactions contemplated herein and in the
         International Underwriting Agreement, except such as may be required
         under the Act and such as may be required under the state securities or
         Blue Sky laws of any jurisdiction, the laws of any jurisdiction outside
         the United States or the by-laws of the NASD in connection with the
         purchase and distribution of the U.S. Securities by the U.S.
         Underwriters and such other approvals as have been obtained.

                           (vii) Neither the sale of the U.S. Option Securities
         by the Selling Shareholder, nor the consummation of any of the
         transactions herein contemplated by the Selling Shareholder or the
         fulfillment of the terms hereof by the Selling Shareholder will
         conflict with, result in a breach or violation of, or constitute a
         default under any law or the terms of any indenture or other agreement
         or instrument to which the Selling Shareholder is a party or bound, or
         any judgment, order or decree applicable to the Selling Shareholder of
         any court, regulatory body, administrative agency, governmental body or
         arbitrator having jurisdiction over the Selling Shareholder.

                           (viii) With respect to any statements in or omissions
         from the Registration Statement or the Prospectuses or any supplements
         thereto made in reliance upon and in conformity with information
         furnished in writing to the Company by the Selling Shareholder, in such
         capacity, specifically for use in connection with the preparation
         thereof, the Selling Shareholder hereby makes the same representations
         and warranties to each U.S. Underwriter as the Company makes to such
         U.S. Underwriters under subparagraph (a) (iii) of this Section 1. The
         U.S. Underwriters acknowledge that the statements set forth under the
         heading "Principal Shareholders" as they relate to the Selling
         Shareholder constitute the only information furnished in writing by or
         on behalf of the Selling Shareholder for inclusion in the Preliminary
         Prospectuses, the Prospectuses or the Registration Statement.

         2.  Purchase and Sale.  (a)  Subject to the terms and conditions and 
in reliance upon the representations and warranties herein set forth, the 
Company agrees to sell to each U.S. Underwriter, and each U.S. Underwriter 
agrees, severally and not jointly, to purchase from the Company, at a purchase 
price of $________ per share, the amount of the U.S. Underwritten Securities 
set forth opposite such U.S. Underwriter's name in Schedule I hereto.

                  (b) Subject to the terms and conditions and in reliance upon
the representations and warranties herein set forth, the Selling Shareholder
hereby grants an option to the several U.S. Underwriters to purchase, severally
and not jointly, up to 840,000 shares of the U.S. Option Securities at the same
purchase price per share as the U.S. Underwriters shall pay for the U.S.
Underwritten Securities. Such option may be exercised only to cover
over-allotments in the sale of the U.S. Underwritten Securities by the U.S.
Underwriters. Such option may be exercised in whole or in part at any time (but
not more than once) on or before the 30th day after the date of the U.S.
Prospectus upon written or telegraphic notice by the U.S. Representatives to the
Selling Shareholder setting forth the number of shares of the U.S. Option
Securities as to which the several U.S. Underwriters are exercising the option
and the settlement date. Delivery of certificates for the shares of U.S. Option
Securities by the Selling Shareholder and payment therefor to the Selling
Shareholder shall be made as provided in Section 3 hereof. The number of shares
of the U.S. Option Securities to be purchased by each U.S. Underwriter shall be
the same percentage of the total number of shares of the U.S. Option Securities
to be purchased by the several U.S. Underwriters as such U.S. Underwriter is
purchasing of the U.S. Underwritten Securities, subject to such adjustments as
you in your absolute discretion shall make to eliminate any fractional shares.

         3. Delivery and Payment. Delivery of and payment for the U.S.
Underwritten Securities (and the U.S. Option Securities if the option provided
for in Section 2(b) hereof shall have been exercised on or before the third
business day prior to the Closing Date) shall be made at 10:00 AM, New York City
time, on ________________, 1997, or such later date (not later than
____________, 1997) as the U.S. Representatives shall designate, which date and
time may be postponed by agreement among the U.S. Representatives and the
Company or as provided in Section 9 hereof (such date and time of delivery and
payment for the Securities being herein called the "Closing Date"). Delivery of
the U.S. Securities shall be made to the U.S. Representatives for the respective
accounts of the several U.S. Underwriters against payment by the several U.S.
Underwriters through the U.S. Representatives of the respective aggregate
purchase prices of the U.S. Securities being sold by the Company (and by the
Selling Shareholder, if applicable) to or upon the order of the Company (and of
the Selling Shareholder, if applicable) by means of a wire transfer of
immediately available funds in accordance with written instructions from the
Company (and from the Selling Shareholder, if applicable). Delivery of the U.S.
Underwritten Securities (and the U.S. Option Securities, if applicable) shall be
made at such location as the U.S. Representatives shall reasonably designate at
least one business day in advance of the Closing Date, and payment for the U.S.


                                      -13-


<PAGE>   14



Securities shall be made at the offices of Jones, Walker, Waechter, Poitevent,
Carrere & Denegre, L.L.P., in New Orleans, Louisiana. Certificates for the U.S.
Securities shall be registered in such names and in such denominations as the
U.S. Representatives may request not less than three full business days in
advance of the Closing Date.

         The Company (and the Selling Shareholder, if applicable) agrees to have
the U.S. Securities available for inspection, checking and packaging by the U.S.
Representatives in New York, New York, not later than 1:00 PM on the business
day prior to the Closing Date.

         If the option provided for in Section 2(b) hereof is exercised after
the third business day prior to the Closing Date, the Selling Shareholder will
deliver (at his own expense) to the U.S. Representatives, at Seven World Trade
Center, New York, New York, on the date specified by the U.S. Representatives
(which shall be within three business days after exercise of such option and is
referred to hereinafter as the "Option Closing Date"), certificates for the U.S.
Option Securities in such names and denominations as the U.S. Representatives
shall have requested against payment of the purchase price thereof to or upon
the order of the Selling Shareholder by means of a wire transfer of immediately
available funds in accordance with written instructions from the Selling
Shareholder. If settlement for the U.S. Option Securities occurs after the
Closing Date, the Company and the Selling Shareholder will deliver to the U.S.
Representatives on the settlement date for the U.S. Option Securities, and the
obligation of the U.S. Underwriters to purchase the U.S. Option Securities shall
be conditioned upon receipt of, supplemental opinions, certificates and letters
confirming as of such date the opinions, certificates and letters delivered on
the Closing Date pursuant to Section 6 hereof.

         It is understood and agreed that the Closing Date shall occur
simultaneously with the "Closing Date" under the International Underwriting
Agreement.

         The Selling Shareholder will pay all applicable state transfer taxes,
if any, involved in the transfer to the several U.S. Underwriters of the
Securities to be purchased by them from the Selling Shareholder and the
respective U.S. Underwriters will pay any additional stock transfer taxes
involved in further transfers.

         4.       Offering by U.S. Underwriters.  It is understood that the 
several U.S. Underwriters propose to offer the U.S. Securities for sale to the 
public as set forth in the U.S. Prospectus.

         5.       Agreements.  (a)  The Company agrees with the several U.S. 
Underwriters that:

                           (i)      The Company will use its best efforts to 
         cause the Registration Statement, if not effective at the Execution 
         Time, and any amendment thereof to become effective.  Prior to the 
         termination of the offering of the Securities, the


                                      -14-


<PAGE>   15



         Company will not file any amendment of the Registration Statement or
         supplement to the U.S. Prospectus without your prior consent, which
         consent shall not be unreasonably withheld. Subject to the foregoing
         sentence, if the Registration Statement has become or becomes effective
         pursuant to Rule 430A, or filing of the U.S. Prospectus is otherwise
         required under Rule 424(b), the Company will cause the U.S. Prospectus,
         properly completed, and any supplement thereto to be filed with the
         Commission pursuant to the applicable paragraph of Rule 424(b) within
         the time period prescribed and will provide evidence satisfactory to
         the U.S. Representatives of such timely filing. The Company will
         promptly advise the U.S. Representatives (A) when the Registration
         Statement, if not effective at the Execution Time, and any amendment
         thereto, shall have become effective, (B) when the U.S. Prospectus, and
         any supplement thereto, shall have been filed (if required) with the
         Commission pursuant to Rule 424(b), (C) when, prior to termination of
         the offering of the Securities, any amendment to the Registration
         Statement shall have been filed or become effective, (D) of any request
         by the Commission for any amendment of the Registration Statement or
         supplement to the U.S. Prospectus or for any additional information,
         (E) of the issuance by the Commission of any stop order suspending the
         effectiveness of the Registration Statement or the institution or
         threatening of any proceeding for that purpose and (F) of the receipt
         by the Company of any notification with respect to the suspension of
         the qualification of the U.S. Securities for sale in any jurisdiction
         or the initiation or threatening of any proceeding for such purpose.
         The Company will use its best efforts to prevent the issuance of any
         such stop order and, if issued, to obtain as soon as possible the
         withdrawal thereof.

                           (ii) If, at any time when a prospectus relating to
         the U.S. Securities is required to be delivered under the Act, any
         event occurs as a result of which the U.S. Prospectus as then
         supplemented would include any untrue statement of a material fact or
         omit to state any material fact necessary to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading, or if it shall be necessary to amend the Registration
         Statement or supplement the U.S. Prospectus to comply with the Act, the
         Exchange Act or the respective rules thereunder, the Company promptly
         will (i) prepare and file with the Commission, subject to the second
         sentence of paragraph (a)(i) of this Section 5, an amendment or
         supplement that will correct such statement or omission or effect such
         compliance and (ii) supply any supplemented U.S. Prospectus to you in
         such quantities as you may reasonably request.

                           (iii) As soon as practicable, the Company will make
         generally available to its security holders and to the U.S.
         Representatives an earnings statement or statements of the Company and
         its Subsidiaries that will satisfy the provisions of Section 11(a) of
         the Act and Rule 158 under the Act.

                           (iv) The Company will furnish to the U.S.
         Representatives and counsel for the U.S. Underwriters, without charge,
         signed copies of the Registration Statement (including exhibits
         thereto) and to each other U.S. Underwriter a copy of the Registration
         Statement (without exhibits thereto) and, so long as delivery of a
         prospectus by a U.S. Underwriter or dealer may be required by the Act,
         as many copies of each U.S. Preliminary Prospectus and the U.S.
         Prospectus and any supplement thereto as the U.S. Representatives may
         reasonably request. The Company will pay the expenses of printing or
         other production of all documents relating to the offering.

                           (v) The Company will arrange for the qualification of
         the U.S. Securities for sale under the laws of such jurisdictions in
         the United States as the U.S. Representatives may designate, will

Stock owned by the Selling Shareholder, or any securities convertible into, or
exchangeable for, shares of Common Stock, other than shares of Common Stock

Canada, or to any non-United States or Canadian Person or to any other dealer
who does not so represent and agree; provided, however, that the foregoing shall
not restrict (A) purchases and sales between the U.S.

                  effective under the Act; any required filing of the
                  Prospectuses, and any supplements thereto, pursuant to Rule
                  424(b) has been made in the manner and within the time period

                  have been instituted or threatened and the Registration
                  Statement and the Prospectuses (other than the financial

                  and the execution and delivery of this Agreement have been
                  duly and validly authorized, and this Agreement has been duly
                  executed and delivered by the Company;

                                    (3) all contracts, agreements, instruments,
                  leases and licenses required to be described in the
                  Registration Statement or the Prospectuses have been so
                  described in all material respects. All contracts, agreements,
                  instruments, leases and licenses required to be filed as an
                  exhibit to the Registration Statement have been so filed or

                                    (4) neither the issuance and sale of the
                  Securities, the execution, delivery and performance by the
                  Company of this Agreement, nor the consummation of any of the

                  under the Act, and such as may be required under state
                  securities or Blue Sky laws, the laws of


                                      -18-

                  jurisdictions outside the United States and the by-laws and
                  rules of the NASD and, if the Registration Statement is not
                  effective under the Act as of the Execution Time, such as may
                  be required (and shall be obtained as provided in this
                  Agreement) under the Act, or (B) results in a breach or
                  violation of any of the terms and conditions of, or constitute

                  lease, license or other agreement or instrument described in
                  the Registration Statement or the Prospectuses or filed as an
                  exhibit to the Registration Statement and to which the Company
                  or any of its Subsidiaries is a party or by which the Company
                  or any of its Subsidiaries or any of their respective
                  properties are bound, or the charter documents or by-laws of
                  the Company or any of its Subsidiaries, or any U.S. statute,
                  rule or regulation (other than state securities or Blue Sky
                  laws or rules or regulations of the NASD with respect to which
                  such counsel expresses no opinion) known by such counsel to be
                  applicable to the Company or any of its Subsidiaries or any
                  judgment, decree or order of any court or other governmental
                  authority or any arbitrator known to such counsel to be
                  applicable to the Company or any of its Subsidiaries;

                                    (5) to the knowledge of such counsel and
                  except as set forth in the Prospectuses, there is not now
                  pending or threatened, any action, suit or proceeding to which
                  the Company or any of its Subsidiaries is a party before or by
                  any court or governmental agency or body (including without
                  limitation proceedings of the Commission pursuant to Section
                  8(b) of the Act) (except that such counsel shall express no
                  opinion as to any state securities or Blue Sky authority)
                  that, if determined adversely to the Company or such
                  Subsidiary, is reasonably likely to result in any material
                  adverse change in the condition (financial or other),
                  business, properties, assets or results of operations of the
                  Company and its subsidiaries taken as a whole, or is
                  reasonably likely to affect the ability of the Company to
                  carry out its obligations hereunder;

                                    (6) the Company has been duly incorporated
                  and each of the Company and the Company's Subsidiaries and is
                  validly existing as a corporation or other business entity in
                  good standing under the laws of the jurisdiction in which it
                  was chartered or organized, with full corporate power and
                  authority to own its properties and conduct its business as
                  described in the Registration Statement and the Prospectuses;
                  and each of the Company and its Subsidiaries is duly qualified
                  to do business as a foreign corporation and is in good
                  standing under the laws of each jurisdiction that requires
                  such qualification wherein it owns or leases properties or
                  conducts business and in which the failure, individually or in
                  the aggregate, to be so qualified could have a material
                  adverse effect on the condition (financial or other),
                  business, properties, assets or results of operations of the
                  Company and its subsidiaries taken as a whole;

                                    (7) all of the outstanding shares of capital
                  stock of each of the Subsidiaries have been duly authorized
                  and validly issued and are fully paid and nonassessable, and
                  all the outstanding shares of capital stock of the
                  Subsidiaries (except in the case of CCC, of which the Company
                  only owns 49% of the outstanding capital stock) are held of
                  record by the Company or its other subsidiaries and, to the
                  knowledge of such counsel, are owned by the Company or its
                  other subsidiaries free and clear of any perfected security
                  interest and, to the knowledge of such counsel, any other
                  security interests, claims, liens or encumbrances except for
                  restrictions imposed by the Act or applicable state securities
                  law or, in the case of CCC, the CCC Shareholders Agreement. To
                  the knowledge of such counsel, such shares of capital stock of
                  the Subsidiaries have not been issued in violation of any
                  preemptive rights or, to the knowledge of such counsel, other
                  rights of first refusal. To the knowledge of such counsel, no
                  options, warrants or other rights to purchase or otherwise
                  acquire any authorized but unissued shares of capital stock of
                  any Subsidiary or any security convertible into shares of such
                  capital stock are now outstanding and no shares of such
                  capital stock have been reserved for issuance;

                                    (8) the Company's authorized equity
                  capitalization is as set forth under the heading
                  "Capitalization" in the Prospectuses, as of the date set forth
                  therein, and as of the date hereof, and the outstanding shares
                  of Common Stock have been duly authorized and validly issued
                  and are fully paid and nonassessable. The Securities have been
                  duly and validly authorized ,and, when issued and delivered to
                  and paid for by the U.S. Underwriters pursuant to this
                  Agreement or the International Underwriters as contemplated by
                  the International Underwriting Agreement will be validly
                  issued (assuming the certificates evidencing such Securities
                  have been duly executed by the Company's Transfer Agent, an
                  assumption which such counsel shall not be required to
                  verify), fully paid and nonassessable. Except pursuant to this
                  Agreement or the International Underwriting Agreement and as
                  set forth in the Prospectuses, no options, warrants,
                  preemptive rights or, to the knowledge of such counsel, any
                  other rights to purchase or otherwise acquire any authorized
                  but unissued shares of Common Stock of the Company or any
                  security convertible into shares of Common Stock of the
                  Company are now outstanding and no shares of Common Stock have
                  been reserved for issuance. To the knowledge of such counsel,
                  no shares of Common Stock are required pursuant to any
                  contract or other right to be included in the Registration
                  Statement, other than the shares held by William J. Dore
                  included therein;

                                    (9) to the knowledge of such counsel,
                  neither the Company nor any of its Subsidiaries is in breach
                  of any term or provision of its charter or by-laws and no
                  default exists (and no event has occurred that with notice


                                      -20-


<PAGE>   21



                  or lapse of time, or both, would constitute a default) in the
                  due performance and observance of any term, covenant or
                  condition of any indenture, mortgage, deed of trust, lease,
                  note, bank loan or credit agreement, license or any other
                  agreement, including without limitation any U.S. government
                  ship financing bonds, described in the Registration Statement
                  or the Prospectuses or filed as an exhibit to the Registration
                  Statement and to which the Company or any of its Subsidiaries
                  is a party or by which the Company or any of its Subsidiaries
                  or any of their respective properties may be bound, which
                  breach or default would have a material adverse effect on the
                  condition (financial or other), business, properties, assets
                  or results of operations of the Company and its subsidiaries
                  taken as a whole; and

                                    (10) the Company is not an "investment
                  company" within the meaning of the Investment Company Act of
                  1940, as amended.

                                    (11) the statements in the International
                  Prospectus under the caption "Certain United States Tax
                  Consequences to Non-United State Holders" constitute fair
                  summaries of the matters referred to therein.

In addition, such counsel shall state that such counsel has participated in
conferences with officers and other representatives of the Company,
representatives of the independent public accountants of the Company, the
Selling Shareholder and representatives of the U.S. Underwriters at which the
contents of the Registration Statement and the Prospectuses were discussed and,
although such counsel is not passing upon and does not assume responsibility for
the accuracy, completeness or fairness of the statements contained in the
Registration Statement or the Prospectuses (except as and to the extent stated
in subparagraph (3) and the first sentence of subparagraph (8) above), such
counsel advises that, on the basis of the foregoing (relying as to materiality
to a large extent upon officers and other representatives of the Company), no
facts came to the attention of such counsel that have caused them to believe
that the Registration Statement or any amendment thereto at the time such
Registration Statement or amendment became effective and on the date hereof,
contained an untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading, or
that the Prospectuses or any supplement thereto at the date of such Prospectuses
or such supplement, and at the date hereof as the case may be, contained an
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading (it being
understood that such counsel need express no comment with respect to the
financial statements and schedules and other financial or statistical data
included or incorporated by reference in the Registration Statement or the
Prospectuses).

         In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws of any jurisdiction other than the State of
Texas and the United States or the Louisiana Business Corporation Law (the
"LBCL"), to the extent they deem proper and so specify in such opinion, upon the
opinion of other counsel of good standing whom they believe to be reliable and
who are satisfactory to counsel for the U.S. Underwriters, and (B) as to matters
of fact, to the extent they deem proper, on certificates of responsible officers
of the Company and public officials.

                           (ii)  the opinion of Kerry Williams, general counsel
         to the Company dated the Closing Date to the effect that:

                                    (1) to the knowledge of such counsel, each
                  of the Company and its Subsidiaries possesses all consents,
                  certificates, approvals, authorizations, orders,
                  registrations, qualifications, licenses and permits of and
                  from all state and federal public, regulatory or governmental
                  agencies and bodies necessary to the ownership, leasing and
                  operation of its properties and the conduct of its business as
                  described in the Registration Statement and the Prospectuses,
                  except where the failure to obtain or maintain any such
                  consent, certificate, approval, authorization, order,
                  registration, qualification, license or permit would not have
                  a material adverse effect upon the condition (financial or
                  other), business, properties, assets or results of operations
                  of the Company and its Subsidiaries taken as a whole, and, to
                  the knowledge of such counsel, neither the Company nor any
                  such Subsidiary has received any notice of proceedings
                  relating to the revocation or modification of any such
                  consent, certificate, approval, authorization, order,
                  registration, qualification, license or permit that, singly or
                  in the aggregate, if the subject of an unfavorable decision,
                  ruling or finding, would result in a material adverse change
                  in the condition (financial or other), business, properties,
                  assets or results of operations of the Company and its
                  Subsidiaries taken as a whole;

                                    (2) to the knowledge of such counsel, each
                  of the Company and its Subsidiaries (and the manner in which
                  each of them conducts its business or proposes to conduct its
                  business) is in material compliance with all laws, ordinances
                  or governmental rules or regulations to which it is subject,
                  including without limitation any rules or regulations of the
                  Minerals Management Service of the United States Department of
                  Interior, the United States Coast Guard and the Environmental
                  Protection Agency;

                                    (3) to the knowledge of such counsel, the
                  Company and its Subsidiaries have good and defensible title to
                  all of the real property, vessels and assets described as
                  owned by each of them in the Prospectuses, in each case free
                  and clear of any security interests, liens, encumbrances,
                  equities, claims and other defects, except (A) such as are
                  disclosed in the


                                      -22-

                  Prospectuses or do not materially and adversely affect the
                  value of such property, and (B) such as do not interfere in
                  any material respect with the use made or proposed to be made
                  of such property by the Company or such
                  Subsidiary; and to the knowledge of such counsel, any real
                  property and buildings held under any lease by the Company or
                  its Subsidiaries are held under leases that are valid,
                  existing and in full force and effect, except where the
                  failure to be valid, existing and in full force and effect
                  would not have a material adverse effect on the condition
                  (financial or other), business, properties, assets or results
                  of operations of the Company and its Subsidiaries taken as a
                  whole; and

                                    (4) to the knowledge of such counsel, the
                  Company and its Subsidiaries own or have the right to use all
                  patents, licenses, sublicenses and rights thereof that are
                  described in the Prospectuses, except for those the absence of
                  which would not in the aggregate have a material adverse
                  effect on the condition (financial or other), business,
                  properties, assets or results of operations of the Company and
                  its Subsidiaries taken as a whole, and, to the knowledge of
                  such counsel, no default exists (and no event has occurred
                  that with notice or lapse of time, or both, would constitute a
                  default) in the due performance of and observance of, and no
                  event has occurred (including in connection with the offering
                  of the Securities contemplated by this Agreement) that would
                  have a material adverse effect on the Company's or any such
                  Subsidiary's right to use the patented equipment and
                  technology currently used by the Company or any such
                  Subsidiary under any term, covenant or condition of any
                  license or sublicense to which the Company or any such
                  Subsidiary is a party.

         In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws of any jurisdiction other than the State of
Texas and the United States or the Louisiana Business Corporation Law (the
"LBCL"), to the extent they deem proper and so specify in such opinion, upon the
opinion of other counsel of good standing whom they believe to be reliable and
who are satisfactory to counsel for the U.S. Underwriters, and (B) as to matters
of fact, to the extent they deem proper, on certificates of responsible officers
of the Company and public officials.

                  (c) In the event the option granted pursuant to Section 2(b)
is exercised, the Selling Shareholder shall have furnished to the U.S.
Representatives the opinion of Vinson & Elkins L.L.P., counsel for the Selling
Shareholder, dated the Option Closing Date or, if the option granted pursuant to
Section 2(b) hereof has been exercised on or before the third business day prior
to the Closing Date, the Closing Date, to the effect that:

                           (i) this Agreement, the Custody Agreement and the
         Power of Attorney have been duly executed and delivered by the Selling
         Shareholder and are valid and binding on the Selling Shareholder, and
         the Selling Shareholder has full


                                      -23-


<PAGE>   24



         legal right and authority to sell, transfer and deliver in the manner
         provided in this Agreement the Securities being sold by the Selling
         Shareholder hereunder;

                           (ii) upon the delivery by the Selling Shareholder to
         the several U.S. Underwriters of certificates for the U.S. Option
         Securities being sold hereunder by the Selling Shareholder against
         payment therefor as provided herein, the U.S. Underwriters (assuming
         they are bona fide purchasers within the meaning of the Uniform
         Commercial Code) will acquire good and marketable title to such U.S.
         Option Securities, free and clear of all liens, encumbrances, equities
         and claims whatsoever;

                           (iii) to the knowledge of such counsel, no consent,
         approval, authorization or order of any court or governmental agency or
         body is required for the consummation by the Selling Shareholder of the
         transactions contemplated herein, except such as may have been obtained
         under the Act and such as may be required under the state securities or
         Blue Sky laws of any jurisdiction or the by-laws of the NASD in
         connection with the purchase and distribution of the Securities by the
         U.S. Underwriters and such other approvals (specified in such opinion)
         as have been obtained; and

                           (iv) neither the sale of the U.S. Option Securities
         by the Selling Shareholder, the execution, delivery and performance by
         the Selling Shareholder of this Agreement, nor the consummation of any
         other of the transactions contemplated herein by the Selling
         Shareholder or the fulfillment of the terms hereof or thereof by the
         Selling Shareholder will result in a breach or violation of, or
         constitute a default under the terms of any indenture or other
         agreement or instrument known to such counsel and to which the Selling
         Shareholder is a party or bound, or any law, judgment, order or decree
         known to such counsel to be applicable to the Selling Shareholder of
         any court, regulatory body, administrative agency, governmental body or
         arbitrator having jurisdiction over the Selling Shareholder.

In rendering such opinion, such counsel may rely (A) as to matters involving the
application of laws of any jurisdiction other than the State of Texas and the
United States or under the LBCL, to the extent they deem proper and specified in
such opinion, upon the opinion of other counsel of good standing whom they
believe to be reliable and who are satisfactory to counsel for the Underwriters,
and (B) as to matters of fact, to the extent they deem proper, on certificates
of the Selling Shareholder and public officials.

                  (d) The U.S. Representatives shall have received from Jones,
Walker, Waechter, Poitevent, Carrere & Denegre, L.L.P., counsel for the U.S.
Underwriters, such opinion or opinions, dated the Closing Date, with respect to
the issuance and sale of the U.S. Securities, the Registration Statement, the
Prospectuses (together with any supplement thereto) and other related matters as
the U.S. Representatives may


                                      -24-

reasonably require, and the Company and the Selling Shareholder shall have
furnished to such counsel such documents as they request for the purpose of
enabling them to pass upon such matters.

                  (e) The Company shall have furnished to the U.S.
Representatives a certificate of the Company, signed by the Chairman of the
Board or the President and the principal financial or accounting officer of the
Company, dated the Closing Date, to the effect that the signers of such
certificate have carefully examined the Registration Statement, the
Prospectuses, any supplements to the Prospectuses, this Agreement and the
International Underwriting Agreement and that:

                           (i) the representations and warranties of the Company
         in this Agreement are true and correct in all material respects on and
         as of the Closing Date with the same effect as if made on the Closing
         Date and the Company has complied with all the agreements and satisfied
         all the conditions on its part to be performed or satisfied at or prior
         to the Closing Date;

                           (ii) no stop order suspending the effectiveness of
         the Registration Statement has been issued and no proceedings for that
         purpose have been instituted or, to the best knowledge of the Company,
         threatened; and

                           (iii) since the date of the most recent financial
         statements included in the Prospectuses (exclusive of any supplement
         thereto), there has been no material adverse change in the condition
         (financial or other), business, properties, assets, prospects or
         results of operations of the Company and its subsidiaries, whether or
         not arising from transactions in the ordinary course of business,
         except as set forth in or contemplated in the Prospectuses (exclusive
         of any supplement thereto).

                  (f) If the Option granted pursuant to Section 2(b) is
exercised, the Selling Shareholder shall have furnished to the U.S.
Representatives a certificate, signed by the Selling Shareholder or an
Attorney-In-Fact, dated the Option Closing Date or, if the option granted by
Section 2(b) hereof has been exercised on or before the third business day prior
to the Closing Date, the Closing Date, to the effect that the signer of such
certificate has carefully examined the Registration Statement, the Prospectuses,
any supplement to the Prospectuses, this Agreement and the International
Underwriting Agreement and that the representations and warranties of the
Selling Shareholder in this Agreement are true and correct in all material
respects on and as of the Option Closing Date or, if the option granted by
Section 2(b) hereof has been exercised on or before the third business day prior
to the Closing Date, as of the Closing Date, to the same effect as if made on
the Option Closing Date or the Closing Date, as the case may be.

                  (g)      At the Execution Time and at the Closing Date, 
Deloitte & Touche LLP shall have furnished to the U.S. Representatives letters,
dated respectively as of the


                                      -25-


<PAGE>   26



Execution Time and as of the Closing Date, in form and substance satisfactory to
the U.S. Representatives, confirming that they are independent accountants
within the meaning of the Act, the Exchange Act and the respective applicable
published rules and regulations thereunder and stating in effect that:

                           (i) in their opinion (A) the audited consolidated
         financial statements and financial statement schedules of the Company
         included or incorporated in the Registration Statement and the
         Prospectuses and reported on by them comply as to form in all material
         respects with the applicable accounting requirements of the Act and the
         related published rules and regulations thereunder and constitute the
         only audited financial statements required to be included or
         incorporated therein, and (B) the pro forma financial information and
         the pro forma consolidated financial statements included or
         incorporated in the Registration Statement and the Prospectuses
         constitute the only pro forma information and pro forma statements
         required to be included or incorporated therein under the applicable
         accounting requirements of the Act and the related published rules and
         regulations.

                           (ii) on the basis of a reading of the latest
         unaudited consolidated financial statements made available by the
         Company; carrying out certain specified procedures (but not an
         examination in accordance with generally accepted auditing standards)
         which would not necessarily reveal matters of significance with respect
         to the comments set forth in such letter; a reading of the minutes of
         the meetings of the shareholders and directors of the Company and its
         Subsidiaries; and inquiries of certain officials of the Company and its
         Subsidiaries who have responsibility for financial and accounting
         matters of the Company and its Subsidiaries as to transactions and
         events subsequent to March 31, 1996, nothing came to their attention
         that caused them to believe that:

                                    (1) any unaudited financial statements
                  included or incorporated in the Registration Statement and the
                  Prospectuses do not comply in form in all material respects
                  with applicable accounting requirements and with the published
                  rules and regulations of the Commission with respect to
                  financial statements included or incorporated in quarterly
                  reports on Form 10-Q under the Exchange Act; and said
                  unaudited financial statements are not in conformity with
                  generally accepted accounting principles applied on a basis
                  substantially consistent with that of the audited financial
                  statements included or incorporated in the Registration
                  Statement and the Prospectuses;

                                    (2) with respect to the period subsequent to
                  March 31, 1996, there were any changes, at a specified date
                  not more than five business days prior to the date of each
                  such letter, in the consolidated long-term debt, less current
                  maturities, of the Company or capital stock of the


                                      -26-


<PAGE>   27



                  Company, and as of the date of the latest available month-end
                  consolidated financial statements, there were any decreases in
                  the consolidated shareholders' equity of the Company, or
                  decreases in consolidated receivables of the Company as
                  compared with the amounts shown on the March 31, 1996
                  consolidated balance sheet included or incorporated in the
                  Registration Statement and the Prospectuses, or for the period
                  from March 31, 1996 to the date of the latest available
                  month-end consolidated financial statements there were any
                  decreases, as compared with the corresponding period in the
                  preceding year, in consolidated contract revenues,
                  consolidated income before income taxes or in total or per
                  share amounts of consolidated net income of the Company,
                  except in all instances for changes or decreases set forth in
                  such letter, in which case the letter shall be accompanied by
                  an explanation by the Company as to the significance thereof
                  unless such explanation is not deemed necessary by the U.S.
                  Representatives; or

                                    (3) any unaudited amounts of contract
                  revenues, net income and net income per average common share
                  included under the heading "Recent Developments" in the
                  Registration Statement and the Prospectuses do not agree with
                  the amounts set forth in the unaudited financial statements
                  for the same periods or were not determined on a basis
                  consistent with that of the corresponding amounts in the
                  audited financial statements included or incorporated in the
                  Registration Statement and the Prospectuses; and

                           (iii) they have performed certain other specified
         procedures as a result of which they determined that certain
         information of an accounting, financial or statistical nature (which is
         limited to accounting, financial or statistical information derived
         from the general accounting records of the Company and its
         Subsidiaries) set forth in the Registration Statement and the
         Prospectuses, including without limitation the information set forth
         under the captions "Prospectus Summary" and "Selected Financial Data"
         and the information included in the "Management's Discussion and
         Analysis of Financial Condition and Results of Operations" in the
         Prospectuses, the information included or incorporated in Items 1, 2,
         6, 7 and 11 of the Company's Annual Report on Form 10-K, incorporated
         in the Registration Statement and the Prospectuses, and the information
         included in the "Management's Discussion and Analysis of Financial
         Condition and Results of Operations" included or incorporated in the
         Company's Quarterly Report on Form 10-Q, incorporated in the
         Registration Statement and Prospectuses agree with the accounting
         records of the Company and its Subsidiaries, excluding any questions of
         legal interpretation.

                           (iv) On the basis of a reading of the unaudited pro
         forma consolidated financial statements included in the Registration
         Statement and Prospectuses, carrying out certain specified procedures;
         inquiries of certain officials


                                      -27-


<PAGE>   28



         of the Company and its Subsidiaries who have responsibility for
         financial and accounting matters; and proving the arithmetic accuracy
         of the application of the pro forma adjustments to the historical
         amounts in the pro forma financial statements, nothing came to their
         attention that caused them to believe that the pro forma consolidated
         financial statements do not comply as to form in all material respects
         with the applicable accounting requirements of Rule 11-02 of Regulation
         S-X or that the pro forma adjustments have not been properly applied to
         the historical amounts in the compilation of such statements.

         References to the Prospectuses in this paragraph (g) include any
supplement thereto at the date of the letter.

                  (h) Subsequent to the Execution Time or, if earlier, the dates
as of which information is given in the Registration Statement (exclusive of any
amendment thereof) and the Prospectuses (exclusive of any supplement thereto),
there shall not have been (i) any change or decrease specified in the letters
referred to in paragraph (g) of this Section 6 or (ii) any change, or any
development involving a prospective change, in or affecting the business or
properties of the Company and its subsidiaries the effect of which, in any case
referred to in clause (i) or (ii) above, is, in the judgment of the U.S.
Representatives, so material and adverse as to make it impractical or
inadvisable to proceed with the offering or delivery of the U.S. Securities as
contemplated by the Registration Statement (exclusive of any amendment thereof)
and the Prospectuses (exclusive of any supplement thereto).

                  (i)      Prior to the Closing Date, the Company shall have 
furnished to the U.S. Representatives such further information, certificates 
and documents as the U.S. Representatives may reasonably request.

                  (j) The closing of the purchase of the International
Securities to be issued and sold by the Company pursuant to the International
Underwriting Agreement shall occur concurrently with the closing described
herein.

         If any of the conditions specified in this Section 6 shall not have
been fulfilled in all material respects when and as provided in this Agreement,
or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to the U.S. Representatives and counsel for the U.S. Underwriters,
this Agreement and all obligations of the U.S. Underwriters hereunder may be
canceled at, or at any time prior to, the Closing Date by the U.S.
Representatives. Notice of such cancellation shall be given to the Company and
the Selling Shareholder in writing or by telephone or telegraph confirmed in
writing.

         7.       Reimbursement of U.S. Underwriters' Expenses.  If the sale of
the Securities provided for herein is not consummated because any condition to 
the obligations of the U.S. Underwriters set forth in Section 6 hereof is not 
satisfied, because of any termination pursuant to Section 10 hereof or because 
of any refusal, inability or failure on the part of


                                      -28-


<PAGE>   29



the Company or the Selling Shareholder to perform any agreement herein or comply
with any provision hereof other than by reason of a default by any of the U.S.
Underwriters, the Company will reimburse the U.S. Underwriters severally upon
demand for all out-of-pocket expenses (including reasonable fees and
disbursements of counsel) that shall have been incurred by them in connection
with the proposed purchase and sale of the Securities. If the Company is
required to make any payments to the U.S. Underwriters under this Section 7
because of the Selling Shareholder's refusal, inability or failure to satisfy
any condition to the obligations of the U.S. Underwriters set forth in Section
6, the Selling Shareholder shall reimburse the Company on demand for all amounts
so paid.

         8. Indemnification and Contribution. (a) The Company and the Selling
Shareholder jointly and severally agree to indemnify and hold harmless each U.S.
Underwriter, the directors, officers, employees and agents of each U.S.
Underwriter and each person who controls any U.S. Underwriter within the meaning
of either the Act or the Exchange Act, against any and all losses, claims,
damages or liabilities, joint or several, to which they or any of them may
become subject under the Act, the Exchange Act or other federal or state
statutory law or regulation, at common law 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 a material
fact contained in the Registration Statement for the registration of the
Securities as originally filed or in any amendment thereof, or in any U.S.
Preliminary Prospectus or in either of the Prospectuses, or in any amendment
thereof or supplement thereto, 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 agree to
reimburse each such indemnified party, as incurred, for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the Company and the Selling Shareholder 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 any such untrue statement or alleged untrue statement or omission or
alleged omission made therein in reliance upon and in conformity with written
information furnished to the Company by or on behalf of any U.S. Underwriter
through the U.S. Representatives specifically for inclusion therein; and further
provided, that such indemnity with respect to any U.S. Preliminary Prospectus
shall not inure to the benefit of a U.S. Underwriter (or any person controlling
a U.S. Underwriter) from whom the person asserting any such loss, claim, damage
or liability purchased the Securities that are the subject thereof, if such
person did not receive a copy of the U.S. Prospectus (or the U.S. Prospectus, as
amended or supplemented) at or prior to the written confirmation of the sale of
such Securities to such person where such delivery of the U.S. Prospectus (or
the U.S. Prospectus, as amended or supplemented) is required by the Act, unless
such failure to deliver was a result of the Company's failure to deliver the
U.S. Prospectus in accordance with Section 5(a)(iv) of this Agreement, and if
the untrue statement or omission of a material fact contained in such U.S.
Preliminary Prospectus was corrected in the U.S. Prospectus (or the U.S.
Prospectus, as amended or supplemented). This indemnity agreement will be in
addition to any liability which the Company or the


                                      -29-


<PAGE>   30



Selling Shareholder may otherwise have. Notwithstanding the provisions of this
Section 8(a), the Selling Shareholder shall not be liable under this Section
8(a) in an amount exceeding the product of the purchase price as set forth in
Section 2 hereof and the number of shares sold by the Selling Shareholder.

                  (b) Each U.S. Underwriter severally agrees to indemnify and
hold harmless the Company, each of its directors, each of its officers who signs
the Registration Statement, and each person who controls the Company within the
meaning of either the Act or the Exchange Act and the Selling Shareholder, to
the same extent as the foregoing indemnity to each U.S. Underwriter, but only
with reference to written information relating to such U.S. Underwriter
furnished to the Company by or on behalf of such U.S. Underwriter through the
U.S. Representatives specifically for inclusion in the documents referred to in
the foregoing indemnity. This indemnity agreement will be in addition to any
liability which any U.S. Underwriter may otherwise have. The Company and the
Selling Shareholder acknowledge that the statements set forth in the last
paragraph of the cover page and under the heading "Underwriting" in any U.S. or
International Preliminary Prospectus and the Prospectuses constitute the only
information furnished in writing by or on behalf of the several U.S.
Underwriters for inclusion in any U.S. or International Preliminary Prospectus
or the Prospectuses, and you, as the U.S. Representatives, confirm that such
statements are correct.

                  (c) Promptly after receipt by an indemnified party under this
Section 8 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 this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless and
to the extent it did not otherwise learn of such action and such failure results
in the forfeiture by the indemnifying party of substantial rights and defenses
and (ii) will not, in any event, relieve the indemnifying party from any
obligations to any indemnified party other than the indemnification obligation
provided in paragraph (a) or (b) above. The indemnifying party shall be entitled
to appoint counsel of the indemnifying party's choice at the indemnifying
party's expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be satisfactory to the indemnified
party. Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel if (i) the use of counsel chosen by the indemnifying party to
represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are


                                      -30-


<PAGE>   31



different from or additional to those available to the indemnifying party, (iii)
the indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party. An indemnifying party will not, without the prior
written consent of the indemnified party or parties, settle or compromise or
consent to the entry of any judgment with respect to any pending or threatened
claim, action, suit or proceeding in respect of which indemnification or
contribution may be sought hereunder (whether or not the indemnified party or
parties are actual or potential parties to such claim or action) unless such
settlement, compromise or consent includes an unconditional release of each
indemnified party from all liability arising out of such claim, action, suit or
proceeding.

                  (d) In the event that the indemnity provided in paragraph (a)
or (b) of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, except as a result of the limitations of the
Selling Shareholder's indemnification liability provided by Section 8(a) hereof,
the Company and the Selling Shareholder, jointly and severally, and the U.S.
Underwriters agree to contribute to the aggregate losses, claims, damages and
liabilities (including legal or other expenses reasonably incurred in connection
with investigating or defending same) (collectively, "Losses") to which the
Company, the Selling Shareholder and one or more of the U.S. Underwriters may be
subject in such proportion as is appropriate to reflect the relative benefits
received by the Company and the Selling Shareholder, on the one hand, and by the
U.S. Underwriters, on the other, from the offering of the Securities; provided,
however, that in no case shall any U.S. Underwriter (except as may be provided
in any agreement among underwriters relating to the offering of the Securities)
be responsible for any amount in excess of the underwriting discount or
commission applicable to the Securities purchased by such U.S. Underwriter
hereunder, and further provided, that in no case shall the Selling Shareholder
be responsible for any amount in excess of the limit set forth in paragraph (a)
above. If the allocation provided by the immediately preceding sentence is
unavailable for any reason, the Company and the Selling Shareholder, jointly and
severally, and the U.S. Underwriters shall contribute in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and the Selling Shareholder, on the one hand, and of the
U.S. Underwriters, on the other, in connection with the statements or omissions
which resulted in such Losses, as well as any other relevant equitable
considerations; provided, however, that in no case shall the Selling Shareholder
be responsible for any amount in excess of the limit set forth in paragraphs (a)
above, respectively. Benefits received by the Company and the Selling
Shareholder shall be deemed to be equal to the total net proceeds from the
offering (before deducting expenses), and benefits received by the U.S.
Underwriters shall be deemed to be equal to the total underwriting discounts and
commissions, in each case as set forth on the cover page of the U.S. Prospectus.
Relative fault shall be determined by reference to whether any alleged untrue
statement or omission relates to information provided by the Company, the
Selling Shareholder or the U.S. Underwriters. The Company, the Selling
Shareholder and the U.S. Underwriters agree that


                                      -31-


<PAGE>   32



it would not be just and equitable if contribution were determined by pro rata
allocation or any other method of allocation that does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this paragraph (d), 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. For purposes of
this Section 8, each person who controls a U.S. Underwriter within the meaning
of either the Act or the Exchange Act and each director, officer, employee and
agent of a U.S. Underwriter shall have the same rights to contribution as such
U.S. Underwriter; each person who controls the Company within the meaning of
either the Act or the Exchange Act, each officer of the Company who shall have
signed the Registration Statement and each director of the Company shall have
the same rights to contribution as the Company; and each agent of the Selling
Shareholder shall have the same rights to contribution as the Selling
Shareholder, subject in each case to the applicable terms and conditions of this
paragraph (d).

         9. Default by a U.S. Underwriter. If any one or more U.S. Underwriters
shall fail to purchase and pay for any of the Securities agreed to be purchased
by such U.S. Underwriter or U.S. Underwriters hereunder and such failure to
purchase shall constitute a default in the performance of its or their
obligations under this Agreement, the remaining U.S. Underwriters shall be
obligated severally to take up and pay for (in the respective proportions that
the amount of U.S. Securities set forth opposite their names in Schedule I
hereto bears to the aggregate amount of U.S. Securities set forth opposite the
names of all the remaining U.S. Underwriters) the Securities which the
defaulting U.S. Underwriter or U.S. Underwriters agreed but failed to purchase;
provided, however, that in the event that the aggregate amount of U.S.
Securities which the defaulting U.S. Underwriter or U.S. Underwriters agreed but
failed to purchase shall exceed 10% of the aggregate amount of U.S. Securities
set forth in Schedule I hereto, the remaining U.S. Underwriters shall have the
right to purchase all, but shall not be under any obligation to purchase any, of
the U.S. Securities, and if such nondefaulting U.S. Underwriters do not purchase
all the U.S. Securities, this Agreement will terminate without liability to any
nondefaulting U.S. Underwriter, the Selling Shareholder or the Company. In the
event of a default by any U.S. Underwriter as set forth in this Section 9, the
Closing Date shall be postponed for such period, not exceeding seven days, as
the U.S. Representatives shall determine in order that the required changes in
the Registration Statement and the U.S. Prospectus or in any other documents or
arrangements may be effected. Nothing contained in this Agreement shall relieve
any defaulting U.S. Underwriter of its liability, if any, to the Company, the
Selling Shareholder and any nondefaulting U.S. Underwriter for damages
occasioned by its default hereunder.

         10.      Termination.  This Agreement shall be subject to termination 
in the absolute discretion of the U.S. Representatives, by notice given to the
Company and the Selling Shareholder prior to delivery of and payment for the
Securities, if prior to such time (i) trading in the Company's Common Stock
shall have been suspended by the Commission or the National Association of
Securities Dealers Automated Quotation National Market

                                      -32-


<PAGE>   33



System or trading in securities generally on the New York Stock Exchange or the
National Association of Securities Dealers Automated Quotation National Market
System shall have been suspended or limited or minimum prices shall have been
established on either of such Exchange or Market System, (ii) a banking
moratorium shall have been declared either by Federal or New York State
authorities or (iii) there shall have occurred any outbreak or escalation of
hostilities, declaration by the United States of a national emergency or war or
other calamity or crisis the effect of which on financial markets is such as to
make it, in the judgment of the U.S. Representatives, impracticable or
inadvisable to proceed with the offering or delivery of the U.S. Securities as
contemplated by the U.S.
Prospectus (exclusive of any supplement thereto).

         11. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers, of the Selling Shareholder and of the U.S. Underwriters
set forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation made by or on behalf of any U.S.
Underwriter, the Selling Shareholder or the Company or any of the officers,
directors or controlling persons referred to in Section 8 hereof, and will
survive delivery of and payment for the U.S. Securities. The provisions of
Sections 7 and 8 hereof shall survive the termination or cancellation of this
Agreement.

         12. Notices. All communications hereunder will be in writing and
effective only on receipt, and, if sent to the U.S. Representatives, will be
mailed, delivered or telegraphed and confirmed to them, care of Salomon Brothers
Inc, at Seven World Trade Center, New York, New York, 10048; or, if sent to the
Company or the Selling Shareholder, will be mailed, delivered or telegraphed and
confirmed to it at 107 Global Circle Drive, Lafayette, Louisiana 70503,
attention of the Legal Department.

         13.      Successors.  This Agreement will inure to the benefit of and 
be binding upon the parties hereto and their respective successors and the 
officers and directors and controlling persons referred to in Section 8 hereof,
and no other person will have any right or obligation hereunder.

         14.      Applicable Law.  This Agreement will be governed by and 
construed in accordance with the laws of the State of New York.

As Representatives of the several International Underwriters,
c/o Salomon Brothers International Limited

Dear Sirs:

         Global Industries, Ltd., a Louisiana corporation (the "Company"),
proposes to sell to the several international underwriters named in Schedule I
hereto (the "International Underwriters"), for whom you (the "International
Representatives") are acting as representatives, 1,400,000 shares of the common
stock, $.01 par value per share (the "Common Stock"), of the Company, (such
shares to be issued and sold by the Company being hereinafter called the
"International Underwritten Securities"). In addition, William J. Dore (the
"Selling Shareholder") proposes to grant to the International Underwriters an
option to purchase up to an additional 210,000 shares of Common Stock (the
"International Option Securities;" the International Option Securities, together
with the International Underwritten Securities, being hereinafter called the
"International Securities") solely to cover over-allotments.

- --------
         *Plus an option to purchase up to 210,000 additional shares to cover 
over-allotments.





<PAGE>   2



         It is understood by all parties that the Company and the Selling
Shareholder are concurrently entering into an agreement dated the date hereof
(the "U.S. Underwriting Agreement") providing for the sale by the Company of
5,600,000 shares of Common Stock (such shares to be sold by the Company pursuant
to the U.S. Underwriting Agreement being hereinafter called the "U.S.
Underwritten Securities") in the United States and Canada through arrangements
with certain underwriters in the United States (the "U.S. Underwriters"), for
whom Salomon Brothers Inc, Howard Weil, Labouisse, Friedrichs Incorporated,
Raymond James & Associates, Inc. and Schroder Wertheim & Co. Incorporated are
acting as representatives (the "U.S. Representatives"). In addition, the Selling
Shareholder proposes to grant to the U.S. Underwriters an option to purchase up
to 840,000 additional shares of Common Stock solely to cover over-allotments
(the "U.S. Option Securities;" the U.S. Option Securities, together with the
U.S. Underwritten Securities, being hereinafter called the "U.S. Securities,"
and the U.S. Securities, together with the International Securities, being
hereinafter called the "Securities"). It is further understood and agreed that
the U.S. Underwriters and the International Underwriters simultaneously are
entering into an agreement between the U.S. Underwriters and International
Underwriters (the "Agreement Between U.S. Underwriters and International
Underwriters") pursuant to which, among other things, the International
Underwriters may purchase from the U.S. Underwriters a portion of the U.S.
Securities to be sold pursuant to the U.S. Underwriting Agreement and the U.S.
Underwriters may purchase from the International Underwriters a portion of the
International Securities to be sold pursuant to this Agreement.

         1.       Representations and Warranties.

                  (a) The Company represents and warrants to, and agrees with,
each International Underwriter as set forth below in this Section 1. Certain
terms used in this Section 1 are defined in paragraph (iv) hereof.

                           (i) The Company meets the requirements for use of
         Form S-3 under the Securities Act of 1933, as amended (the "Act"), and
         has filed with the Securities and Exchange Commission (the
         "Commission") a registration statement (file number 333-18773) on Form
         S-3, including a related preliminary prospectus, for the registration
         under the Act of the offering and sale of the Securities. The Company
         may have filed one or more amendments thereto, including the related
         preliminary prospectuses, each of which has previously been furnished
         to you. The Company will next file with the Commission either (A) prior
         to effectiveness of such registration statement, a further amendment to
         such registration statement (including the form of final prospectuses)
         or (B) after effectiveness of such registration statement, final
         prospectuses in accordance with Rules 430A and 424(b)(1) or (4). In the
         case of clause (B), the Company has included in such registration
         statement, as amended at the Effective Date, all information (other
         than Rule 430A Information) required by the Act and the rules
         thereunder to be included in the Prospectuses with respect to the
         Securities and the offering thereof. As filed,


                                       -2-


<PAGE>   3



         such amendment and form of final prospectuses, or such final
         prospectuses, shall contain all Rule 430A Information, together with
         all other such required information, with respect to the Securities and
         the offering thereof and, except to the extent the International
         Representatives shall agree in writing to a modification, shall be in
         all substantive respects in the form furnished to you prior to the
         Execution Time or, to the extent not completed at the Execution Time,
         shall contain only such specific additional information and other
         changes (beyond that contained in the latest International Preliminary
         Prospectus) as the Company has advised you, prior to the Execution
         Time, will be included or made therein.

                           (ii) It is understood that two forms of prospectuses
         are to be used in connection with the offering and sale of the
         Securities: one form of prospectus relating to the U.S. Securities,
         which are to be offered and sold to United States and Canadian Persons,
         and one form of prospectus relating to the International Securities,
         which are to be offered and sold to persons other than United States
         and Canadian Persons. Such form of prospectus relating to the U.S.
         Securities as first filed pursuant to Rule 424(b) or, if no filing
         pursuant to Rule 424(b) is made, such form of prospectus included in
         the Registration Statement at the Effective Date, is hereinafter called
         the "U.S. Prospectus;" such form of prospectus relating to the
         International Securities as first filed pursuant to Rule 424(b) or, if
         no filing pursuant to Rule 424(b) is made, such form of prospectus
         included in the Registration Statement at the Effective Date, is
         hereinafter called the "International Prospectus;" and the U.S.
         Prospectus and the International Prospectus are hereinafter
         collectively called the "Prospectuses."

                           (iii) On the Effective Date, the Registration
         Statement did or will, and when the Prospectuses are first filed (if
         required) in accordance with Rule 424(b) and on each Closing Date, each
         Prospectus (and any supplements thereto) will, comply in all material
         respects with the applicable requirements of the Act and the Securities
         Exchange Act of 1934, as amended (the "Exchange Act"), and the
         respective rules thereunder; on the Effective Date, the Registration
         Statement did not or will not contain any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary in order to make the statements therein, in light
         of the circumstances under which they were made, not misleading; and,
         on the Effective Date, each Prospectus, if not filed pursuant to Rule
         424(b), did not or will not, and on the date of any filing pursuant to
         Rule 424(b) and on the Closing Date, each Prospectus (together with any
         supplement thereto) will not, include any untrue statement of a
         material fact or omit to state a material fact necessary in order to
         make the statements therein, in light of the circumstances under which
         they were made, not misleading; provided, however, that the Company

         and Prospectuses present fairly the information shown therein and have
         been derived from the consolidated financial statements of the Company,

         nor any of its Subsidiaries has incurred any material liabilities or

         material transactions, in each case not in the ordinary course of
         business, and there has not been any material change in the capital

         results of operations of the Company and its subsidiaries taken as a
         whole.

         the execution, delivery or performance of this Agreement by the Company
         nor the consummation of the transactions herein contemplated and the
         fulfillment of the terms hereof by the Company, (A) requires the
         consent, approval, authorization, registration or qualification of or
         with any governmental authority or order of any court, except such as
         have been obtained, such as may be required under state securities or
         Blue Sky laws, the laws of jurisdictions outside the United States or
         the by-laws of the National Association of Securities Dealers, Inc.
         (the "NASD"), and, if the Registration Statement is not effective under
         the Act as of the Execution Time, such as may be required (and shall be
         obtained as provided in this Agreement) under the Act, or (B) conflicts
         with or results in a breach or violation of any of the terms and
         conditions of, or constitutes a default under, any indenture, mortgage,
         deed of trust, lease, license or other agreement or instrument to which
         the Company or any of its Subsidiaries is a party or by which the
         Company or any of its Subsidiaries or any of their respective
         properties are bound, or the charter or by-laws of the Company or any
         of its Subsidiaries, or any statute, rule or regulation applicable to
         the Company or any of its Subsidiaries or any judgment, decree, or
         order of any court or other governmental authority or arbitrator
         applicable to the Company or any of its Subsidiaries, which breach or
         default could have a material adverse effect on the


                                       -6-

         condition (financial or other), business, properties, assets or results
         of operations of the Company and its subsidiaries taken as a whole.

                           (xi) Except as set forth in the Prospectuses, there
         is not now pending or, to the best knowledge of the Company,
         threatened, any action, suit or proceeding to which the Company or any
         of its subsidiaries is a party before or by any court or governmental
         agency or body (including without limitation proceedings of the
         Commission pursuant to Section 8(b) of the Act or by any Blue Sky
         authority) that is reasonably likely to (A) result in any material
         adverse change in the condition (financial or other), business,
         properties, assets or results of operations of the Company and its
         subsidiaries taken as a whole, or (B) materially and adversely affect
         the ability of the Company to carry out its obligations hereunder.

                           (xii) Each of the Company and its Subsidiaries has
         been duly incorporated and is validly existing as a corporation or
         other business entity, as the case may be, in good standing under the
         laws of the jurisdiction in which it was chartered or organized, with
         full corporate power and authority to own its properties and conduct
         its business as described in the Registration Statement and the
         Prospectuses. Each of the Company and its Subsidiaries is duly
         qualified to do business and is in good standing as a foreign
         corporation under the laws of each jurisdiction in which it owns or
         leases properties or conducts business and in which the failure,
         individually or in the aggregate, to be so qualified could have a
         material adverse effect on the condition (financial or other),
         business, properties, assets or results of operations of the Company
         and its subsidiaries taken as a whole. Each of the Company and its
         Subsidiaries possesses all consents, certificates, approvals,
         authorizations, orders, registrations, qualifications, licenses and
         permits of and from all state and federal public, regulatory or
         governmental agencies and bodies necessary to the ownership, leasing
         and operation of its properties and the conduct of its business as
         described in the Registration Statement and the Prospectuses, except
         where the failure to obtain and maintain any such consent, certificate,
         approval, authorization, order, registration, qualification, license or
         permit would not have a material adverse effect on the condition
         (financial or other), business, properties, assets or results of
         operations of the Company and its subsidiaries taken as a whole, and no
         such consent, certificate, approval, authorization, order,
         registration, qualification, license or permit contains any restriction
         that would prevent the Company or any of its Subsidiaries from owning
         and operating its properties and conducting its business as described
         in the Registration Statement and the Prospectuses. Neither the Company
         nor any such Subsidiary has received any notice of proceedings relating
         to the revocation or modification of any such consent, certificate,
         approval, authorization, order, registration, qualification, license or
         permit that, singly or in the aggregate, if the subject of an
         unfavorable decision, ruling or finding, would result in a material
         adverse change in the condition (financial or other), business,
         properties, assets or results of operations of the Company and its
         subsidiaries taken as a whole.

                           (xiii) All outstanding capital stock of each of the
         Subsidiaries has been duly authorized, is validly issued, fully paid
         and nonassessable and is owned by the Company, either directly or
         indirectly through wholly-owned subsidiaries (except in the case of
         CCC, of which the Company only owns 49% of the outstanding capital
         stock), free and clear of any security interests, claims, liens or
         encumbrances except for restrictions imposed by the Act or applicable
         state securities laws or, in the case of CCC, the agreement entered
         into by and among the shareholders of CCC dated December 23, 1996 ("CCC
         Shareholders Agreement"). None of the outstanding capital stock of any
         of the Subsidiaries has been issued in violation of any preemptive
         rights or rights of first refusal. No options, warrants or other rights
         to purchase or otherwise acquire any authorized but unissued shares of
         capital stock of any of the Subsidiaries or any security convertible
         into shares of such capital stock are now outstanding and no shares of
         capital stock of any of the Subsidiaries have been reserved for
         issuance. Except for the shares of capital stock of each of the
         subsidiaries owned by the Company or one or more subsidiaries of the
         Company, neither the Company nor any subsidiary of the Company owns any
         shares of stock or any other equity securities of any corporation or
         has any equity interest in any form of partnership, association or
         other entity (except as disclosed on Schedule II to the U.S.
         Underwriting Agreement).

                           (xiv) The Company's authorized and outstanding equity
         capitalization is as set forth under the heading "Capitalization" in
         the Prospectuses, as of the date set forth therein, and the outstanding
         shares of Common Stock have been duly authorized and validly issued and
         are fully paid and nonassessable. The Securities have been duly
         authorized and, when issued and delivered to and paid for by the
         International Underwriters pursuant to this Agreement and the U.S.
         Underwriters pursuant to the U.S. Underwriting Agreement, will be
         validly issued, fully paid and nonassessable. No further approval or
         authority of the shareholders or the directors of the Company or,
         except in the case of the Act and Blue Sky laws of the various states
         and the by-laws of the NASD, of any U.S. governmental authority or
         agency are required for the issuance and sale of the Securities as
         contemplated herein or as contemplated in the U.S. Underwriting
         Agreement. Except as set forth in the Prospectuses, no options,
         warrants, preemptive rights or other rights to purchase or otherwise
         acquire any authorized but unissued shares of Common Stock of the
         Company or any security convertible into shares of Common Stock of the
         Company are now outstanding and no shares of Common Stock have been
         reserved for issuance. No shares of Common Stock are required pursuant
         to any contract or other right to be included in the Registration
         Statement, other than the shares held by William J. Dore included
         therein.

                           (xv) Neither the Company nor any of its Subsidiaries
         (nor the manner in which any of them conducts its business or proposes
         to conduct its business) is in violation of any law, ordinance or
         governmental rule or regulation to


                                       -8-

         which it is subject, including without limitation any rules or
         regulations of the Minerals Management Service of the United States
         Department of Interior, the United States Coast Guard, the
         Environmental Protection Agency and any other environmental authority,
         except those violations that would not have a material adverse effect
         on the condition (financial or other), business, properties, assets or
         results of operations of the Company and its subsidiaries taken as a
         whole.

                           (xvi) Neither the Company nor any of its Subsidiaries
         is in breach of any term of its respective charter, by-laws or other
         organizational documents; and no default exists (and no event has
         occurred that with notice or lapse of time, or both, would constitute a
         default) in the due performance and observance of any term, covenant or
         condition of any indenture, mortgage, deed of trust, lease, note, bank
         loan or credit agreement, license or any other agreement or instrument,
         including without limitation any U.S. government ship financing bonds,
         to which the Company or any of its Subsidiaries is a party or by which
         the Company or any of its Subsidiaries or any of their respective
         properties may be bound, which breach or default would have a material
         adverse effect on the condition (financial or other), business,
         properties, assets or results of operations of the Company and it
         subsidiaries taken as a whole.

                           (xvii) The Company and its Subsidiaries have good and
         defensible title to all of the real property, vessels and assets
         described as owned by each of them in the Prospectuses, in each case
         free and clear of any security interests, liens, encumbrances,
         equities, claims and other defects, except (A) such as are disclosed in
         the Prospectuses or do not materially and adversely affect the value of
         such property, and (B) such as do not interfere in any material respect
         with the use made or proposed to be made of such property by the
         Company or such Subsidiary; and any real property and buildings held
         under any lease by the Company or its Subsidiaries are held under
         leases that are valid, existing and in full force and effect, except
         where the failure to be valid, existing and in full force and effect
         would not have a material adverse effect on the condition (financial or
         other), business, properties, assets or results of operations of the
         Company and its subsidiaries taken as a whole.

                           (xviii) The Company has in effect with insurers of
         recognized financial responsibility insurance against such losses and
         risks and in amounts that the Company reasonably believes are adequate
         in light of the business conducted by the Company and its subsidiaries
         and the properties owned by them; and the Company has no reason to
         believe, based on the financial position and operations of the Company
         and its subsidiaries, that the Company will not be able to renew its
         existing insurance coverage as and when such coverage expires or to
         obtain similar coverage from similar insurers as may be necessary to
         continue their business at a cost that would not have a material
         adverse effect on the condition (financial or


                                       -9-

         other), business, properties, assets or results of operations of the
         Company and its subsidiaries taken as a whole.

                           (xix) The Company and its subsidiaries own or have
         the right to use all patents, patent applications, trademarks, service
         marks, trade names, licenses, sublicenses and rights thereof that are
         described in the Prospectuses or are necessary for the conduct of their
         respective businesses in the manner in which it is being conducted,
         except for those the absence of which would not in the aggregate have a
         material adverse effect on the business and operations of the Company
         and its subsidiaries taken as a whole, and no default exists (and no
         event has occurred that with notice or lapse of time, or both, would
         constitute a default) in the due performance of and observance of, and
         no event has occurred (including in connection with the offering of the
         Securities contemplated by this Agreement) that would effect the
         Company's or any such subsidiary's right to use the equipment and
         technology currently used by the Company or any such subsidiary under
         any term, covenant or condition of any license or sublicense to which
         the Company or any such subsidiary is a party except where the loss of
         such right or rights would not have a material adverse effect on the
         results of operations of the company and its subsidiaries, taken as a
         whole.

                           (xx) No labor disturbance, strike or slowdown exists
         with any employees of the Company or any of its Subsidiaries or, to the
         best knowledge of the Company, is threatened that in any such case is
         reasonably likely to have a material adverse effect on the condition
         (financial or other), business, properties, assets or results of
         operations of the Company and its subsidiaries taken as a whole.

                           (xxi) None of the Company, its subsidiaries, or any
         officer, director or affiliate of them has taken or will take, directly
         or indirectly, any action designed to cause or result in, or that has
         constituted or might reasonably be expected to cause or result in, the
         stabilization or manipulation of the price of any securities of the
         Company to facilitate the sale or resale of the Securities.

                           (xxii) The Company and its Subsidiaries have filed
         all federal, state and foreign income and franchise tax returns
         required to be filed and have paid all taxes shown thereon to be due,
         except for those taxes that are being contested in good faith or with
         respect to which an extension has been granted; and there is no tax
         deficiency that has been, or, to the best knowledge of the Company,
         might be, asserted against the Company, any of its Subsidiaries or any
         of their respective properties or assets that would have a material
         adverse effect on the condition (financial or other), business,
         properties, assets or results of operations of the Company and its
         subsidiaries taken as a whole.

                           (xxiii) The Company is not an "investment company"
         within the meaning of the Investment Company Act of 1940, as amended,
         and this transaction will not cause the Company to become an investment
         company subject to registration under such Act.

                  (b)      The Selling Shareholder represents and warrants to,
and agrees with, each International Underwriter that:

                           (i) The Selling Shareholder is the sole and lawful
         owner of the Securities to be sold by the Selling Shareholder hereunder
         and, upon sale and delivery of, and payment for, such Securities, as
         provided herein, the Selling Shareholder will convey to the
         International Underwriters good and marketable title to such
         Securities, free and clear of all liens, encumbrances, equities and
         claims whatsoever.

                           (ii) The Selling Shareholder has no reason to believe
         that the representations and warranties of the Company contained in
         this Section 1 are not true and correct, is familiar with the
         Registration Statement and has no knowledge that the Registration
         Statement or the Prospectuses or any supplement thereto contains any
         untrue statement of a material fact or omits to state any material fact
         required to be stated therein or necessary in order to make the
         statements therein, in light of the circumstances under which they were
         made, not misleading; provided, however, that the Selling Shareholder
         makes no representations or warranties as to the information contained
         in or omitted from the Registration Statement or the Prospectuses (or
         any supplement thereto) in reliance upon and in conformity with
         information furnished in writing to the Company by or on behalf of any
         International Underwriter through the International Representatives
         specifically for inclusion in the Registration Statement or the
         Prospectuses (or any supplement thereto); and the sale of the
         Securities by the Selling Shareholder pursuant hereto is not prompted
         by any material adverse information concerning the Company or any
         Subsidiary that is not set forth in the Prospectuses or any supplement
         thereto.

                           (iii) The Selling Shareholder has not taken and will
         not take, directly or indirectly, any action designed to cause or
         result in, or that has constituted or might reasonably be expected to
         cause or result in, stabilization or manipulation of the price of any
         securities of the Company to facilitate the sale or resale of the
         Securities.

                           (iv)     This Agreement and the U.S. Underwriting 
         Agreement have been duly executed and delivered by the Selling 
         Shareholder.

                           (v) Certificates in negotiable form for the
         Securities of the Selling Shareholder to be sold hereunder have been
         placed in custody, for delivery pursuant to the terms of this
         Agreement, under a Custody Agreement and related


                                      -11-


<PAGE>   12



         Power-of-Attorney executed and delivered by the Selling Shareholder, in
         the form heretofore furnished you (the "Custody Agreement" and the
         "Power-of-Attorney," respectively) with Michael J. Pollock, as
         Custodian and Attorney-in-Fact (the "Custodian"); the Securities
         represented by the certificates so held in custody for the Selling
         Shareholder are subject to the interests hereunder of the International
         Underwriters and the Company; the arrangements for custody and delivery
         of such certificates, made by the Selling Shareholder hereunder and
         under the Custody Agreement, are not subject to termination by any act
         of the Selling Shareholder, or by operation of law, whether by the
         death or incapacity of the Selling Shareholder or the occurrence of any
         other event; and if any such death, incapacity or any other event shall
         occur before delivery of such Securities hereunder, certificates for
         the Securities will be delivered by the Custodian in accordance with
         the terms and conditions of this Agreement and the Custody Agreement as
         if such death, incapacity or other event had not occurred, regardless
         of whether or not the Custodian shall have received notice of such
         death, incapacity or other event.

                           (vi) No consent, approval, authorization,
         registration or qualification of or with any governmental authority or
         order of any court is required for the consummation by the Selling
         Shareholder of the transactions contemplated herein and in the U.S.
         Underwriting Agreement, except such as may be required under the Act
         and such as may be required under the state securities or Blue Sky laws
         of any jurisdiction, the laws of any jurisdiction outside the United
         States or the by-laws of the NASD in connection with the purchase and
         distribution of the International Securities by the International
         Underwriters and such other approvals as have been obtained.

                           (vii) Neither the sale of the International Option
         Securities by the Selling Shareholder nor the consummation of any
         transactions herein contemplated by the Selling Shareholder or the
         fulfillment of the terms hereof by the Selling Shareholder will
         conflict with, result in a breach or violation of, or constitute a
         default under any law or the terms of any indenture or other agreement
         or instrument to which the Selling Shareholder is a party or bound, or
         any judgment, order or decree applicable to the Selling Shareholder of
         any court, regulatory body, administrative agency, governmental body or
         arbitrator having jurisdiction over the Selling Shareholder.

                           (viii) With respect to any statements in or omissions
         from the Registration Statement or the Prospectuses or any supplements
         thereto made in reliance upon and in conformity with information
         furnished in writing to the Company by the Selling Shareholder, in such
         capacity, specifically for use in connection with the preparation
         thereof, the Selling Shareholder hereby makes the same representations
         and warranties to each International Underwriter as the Company makes
         to such International Underwriters under subparagraph (a) (iii) of this
         Section 1. The International Underwriters acknowledge that the
         statements set forth under


                                      -12-


<PAGE>   13



         the heading "Principal Shareholders" as they relate to the Selling
         Shareholder constitute the only information furnished in writing by or
         on behalf of the Selling Shareholder for inclusion in any Preliminary
         Prospectus, the Prospectuses or the Registration Statement.

         2. Purchase and Sale. (a) Subject to the terms and conditions and in
reliance upon the representations and warranties herein set forth, the Company
agrees to sell to each International Underwriter, and each International
Underwriter agrees, severally and not jointly, to purchase from the Company, at
a purchase price of $________ per share, the amount of the International
Underwritten Securities set forth opposite such International Underwriter's name
in Schedule I hereto.

                  (b) Subject to the terms and conditions and in reliance upon
the representations and warranties herein set forth, the Selling Shareholder
hereby grants an option to the several International Underwriters to purchase,
severally and not jointly, up to 210,000 shares of the International Option
Securities, at the same purchase price per share as the International
Underwriters shall pay for the International Underwritten Securities. Such
option may be exercised only to cover over-allotments in the sale of the
International Underwritten Securities by the International Underwriters. Such
option may be exercised in whole or in part at any time (but not more than once)
on or before the 30th day after the date of the International Prospectus upon
written or telegraphic notice by the International Representatives to the
Selling Shareholder setting forth the number of shares of the International
Option Securities as to which the several International Underwriters are
exercising the option and the settlement date. Delivery of certificates for the
shares of International Option Securities by the Selling Shareholder and payment
therefor to the Selling Shareholder shall be made as provided in Section 3
hereof. The number of shares of the International Option Securities to be
purchased by each International Underwriter shall be the same percentage of the
total number of shares of the International Option Securities to be purchased by
the several International Underwriters as such International Underwriter is
purchasing of the International Underwritten Securities, subject to such
adjustments as you in your absolute discretion shall make to eliminate any
fractional shares.

         3. Delivery and Payment. Delivery of and payment for the International
Underwritten Securities (and the International Option Securities if the option
provided for in Section 2(b) hereof shall have been exercised on or before the
third business day prior to the Closing Date) shall be made at 10:00 AM, New
York City time, on ________________, 1997, or such later date (not later than
____, 1997) as the International Representatives shall designate, which date and
time may be postponed by agreement among the International Representatives and
the Company or as provided in Section 9 hereof (such date and time of delivery
and payment for the Securities being herein called the "Closing Date"). Delivery
of the International Securities shall be made to the International
Representatives for the respective accounts of the several International
Underwriters against payment by the several International Underwriters through
the


                                      -13-


<PAGE>   14



International Representatives of the respective aggregate purchase prices of the
International Securities being sold by the Company (and by the Selling
Shareholder, if applicable) to or upon the order of the Company (and of the
Selling Shareholder if, applicable) by means of a wire transfer of immediately
available funds in accordance with written instructions from the Company (and
from the Selling Shareholder, if applicable). Delivery of the International
Underwritten Securities (and the International Option Securities, if applicable)
shall be made at such location as the International Representatives shall
reasonably designate at least one business day in advance of the Closing Date,
and payment for the International Securities shall be made at the offices of
Jones, Walker, Waechter, Poitevent, Carrere & Denegre, L.L.P., in New Orleans,
Louisiana. Certificates for the International Securities shall be registered in
such names and in such denominations as the International Representatives may
request not less than three full business days in advance of the Closing Date.

         The Company (and the Selling Shareholder, if applicable) agrees to have
the International Securities available for inspection, checking and packaging by
the International Representatives in New York, New York, not later than 1:00 PM
on the business day prior to the Closing Date.

         If the option provided for in Section 2(b) hereof is exercised after
the third business day prior to the Closing Date, the Selling Shareholder will
deliver (at his own expense) to the International Representatives, at Seven
World Trade Center, New York, New York, on the date specified by the
International Representatives (which shall be within three business days after
exercise of such option and is referred to hereinafter as the "Option Closing
Date"), certificates for the International Option Securities in such names and
denominations as the International Representatives shall have requested against
payment of the purchase price thereof to or upon the order of the Selling
Shareholder by means of a wire transfer of immediately available funds in
accordance with written instructions from the Selling Shareholder. If settlement
for the International Option Securities occurs after the Closing Date, the
Company and the Selling Shareholder will deliver to the International
Representatives on the settlement date for the International Option Securities,
and the obligation of the International Underwriters to purchase the
International Option Securities shall be conditioned upon receipt of,
supplemental opinions, certificates and letters confirming as of such date the
opinions, certificates and letters delivered on the Closing Date pursuant to
Section 6 hereof.

         It is understood and agreed that the Closing Date shall occur 
simultaneously with the "Closing Date" under the U.S. Underwriting Agreement.

         The Selling Shareholder will pay all applicable state transfer taxes,
if any, involved in the transfer to the several International Underwriters of
the International Securities to be purchased by them from the Selling
Shareholder and the respective International Underwriters will pay any
additional stock transfer taxes involved in further transfers.

         4.       Offering by International Underwriters.  It is understood 
that the several International Underwriters propose to offer the International 
Securities for sale to the public as set forth in the International Prospectus.

         5.       Agreements.  (a)  The Company agrees with the several 
International Underwriters that:

                           (i) The Company will use its best efforts to cause
         the Registration Statement, if not effective at the Execution Time, and
         any amendment thereof to become effective. Prior to the termination of
         the offering of the Securities, the Company will not file any amendment
         of the Registration Statement or supplement to the International
         Prospectus without your prior consent, which consent shall not be
         unreasonably withheld. Subject to the foregoing sentence, if the
         Registration Statement has become or becomes effective pursuant to Rule
         430A, or filing of the International Prospectus is otherwise required
         under Rule 424(b), the Company will cause the International Prospectus,
         properly completed, and any supplement thereto to be filed with the
         Commission pursuant to the applicable paragraph of Rule 424(b) within
         the time period prescribed and will provide evidence satisfactory to
         the International Representatives of such timely filing. The Company
         will promptly advise the International Representatives (A) when the
         Registration Statement, if not effective at the Execution Time, and any
         amendment thereto, shall have become effective, (B) when the
         International Prospectus, and any supplement thereto, shall have been
         filed (if required) with the Commission pursuant to Rule 424(b), (C)
         when, prior to termination of the offering of the Securities, any
         amendment to the Registration Statement shall have been filed or become
         effective, (D) of any request by the Commission for any amendment of
         the Registration Statement or supplement to the International
         Prospectus or for any additional information, (E) of the issuance by
         the Commission of any stop order suspending the effectiveness of the
         Registration Statement or the institution or threatening of any
         proceeding for that purpose and (F) of the receipt by the Company of
         any notification with respect to the suspension of the qualification of
         the International Securities for sale in any jurisdiction or the
         initiation or threatening of any proceeding for such purpose. The
         Company will use its best efforts to prevent the issuance of any such
         stop order and, if issued, to obtain as soon as possible the withdrawal
         thereof.

                           (ii) If, at any time when a prospectus relating to
         the International Securities is required to be delivered under the Act,
         any event occurs as a result of which the International Prospectus as
         then supplemented would include any untrue statement of a material fact
         or omit to state any material fact necessary to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading, or if it shall be necessary to amend the Registration
         Statement or supplement the International Prospectus to comply with the
         Act, the Exchange Act or the respective rules thereunder, the Company
         promptly will (i) prepare and file with the Commission, subject to the
         second sentence of paragraph (a)(i) of this


                                      -15-


<PAGE>   16



         Section 5, an amendment or supplement that will correct such statement
         or omission or effect such compliance and (ii) supply any supplemented
         International Prospectus to you in such quantities as you may
         reasonably request.

                           (iii) As soon as practicable, the Company will make
         generally available to its security holders and to the International
         Representatives an earnings statement or statements of the Company and
         its Subsidiaries that will satisfy the provisions of Section 11(a) of
         the Act and Rule 158 under the Act.

                           (iv) The Company will furnish to the International
         Representatives and counsel for the International Underwriters, without
         charge, signed copies of the Registration Statement (including exhibits
         thereto) and to each other International Underwriter a copy of the
         Registration Statement (without exhibits thereto) and, so long as
         delivery of a prospectus by an International Underwriter or dealer may
         be required by the Act, as many copies of the International Preliminary
         Prospectus and the International Prospectus and any supplement thereto
         as the International Representatives may reasonably request. The
         Company will pay the expenses of printing or other production of all
         documents relating to the offering.

                           (v) The Company will arrange for the qualification of
         the International Securities for sale under the laws of such
         jurisdictions in the United States as the International Representatives
         may designate, will maintain such qualifications in effect so long as
         required for the distribution of the International Securities and will
         pay the fee of the NASD, in connection with its review of the offering.

                           (vi) The Company will not, for a period of 180 days
         following the Execution Time, without the prior written consent of the
         International Representatives, offer, sell or contract to sell, or
         otherwise dispose of, directly or indirectly, or announce the offering
         of, any other shares of Common Stock or any securities convertible
         into, or exchangeable for, shares of Common Stock; provided, however,
         that the Company may issue and sell Common Stock pursuant to any
         employee benefit plan, stock ownership plan or dividend reinvestment
         plan of the Company in effect at the Execution Time and described in
         the Registration Statement and Prospectuses.

                  (b) The Selling Shareholder agrees with the several
International Underwriters that during the period of 180 days following the
Execution Time the Selling Shareholder will not, without the prior written
consent of the International Representatives, offer, sell or contract to sell,
or otherwise dispose of, directly or indirectly, or announce the offering of,
any other shares of Common Stock owned by the Selling Shareholder, or any
securities convertible into, or exchangeable for, shares of Common Stock, other
than shares of Common Stock disposed of as bona fide gifts to persons who agree
in writing to be bound by the foregoing restrictions.

<PAGE>   17



                  (c) Each International Underwriter agrees that (i) it is not
purchasing any of the International Securities for the account of any United
States or Canadian Person, (ii) it has not offered or sold, and will not offer
or sell, directly or indirectly, any of the International Securities or
distribute any International Prospectus to any person in the United States or
Canada, or to any United States or Canadian Person, and (iii) any dealer to whom
it may sell any of the International Securities will represent that it is not
purchasing for the account of any United States or Canadian Person and agree
that it will not offer or resell, directly or indirectly, any of the
International Securities in the United States or Canada, or to any United States
or Canadian Person or to any other dealer who does not so represent and agree;
provided, however, that the foregoing shall not restrict (A) purchases and sales
between the U.S. Underwriters on the one hand and the International Underwriters
on the other hand pursuant to the Agreement Between U.S. Underwriters and
International Underwriters, (B) stabilization transactions contemplated under

following events:

         restrictions set forth in paragraph (c) of this Section 5 and Section 
         5(c) of the U.S. Underwriting Agreement; or

                           (ii) the expiration of a period of 30 days after the
         Closing Date, unless (A) the U.S. Representatives shall have given
         notice to the Company and the International Representatives that the
         distribution of the U.S. Securities by the U.S. Underwriters has not
         yet been completed, or (B) the International Representatives shall have
         given notice to the Company and the U.S. Representatives that the
         distribution of the International Securities by the International
         Underwriters has not yet been completed. If such notice by the U.S.
         Representatives or the International Representatives is given, the
         agreements set forth in such paragraph (c) shall survive until the
         earlier of (1) the event referred to in clause (i) of this subsection
         (d) or (2) the expiration of an additional period of 30 days from the

                           (i)      the opinion of Vinson & Elkins L.L.P., 
         counsel for the Company, dated the Closing Date, to the effect that:

                                    (1) the Registration Statement has become
                  effective under the Act; any required filing of the
                  Prospectuses, and any supplements thereto, pursuant to Rule
                  424(b) has been made in the manner and within the time period
                  required by Rule 424(b); to the knowledge of such counsel, no
                  stop order suspending the effectiveness of the Registration
                  Statement has been issued, no proceedings for that purpose
                  have been instituted or threatened and the Registration
                  Statement and the Prospectuses (other than the financial
                  statements and other financial and statistical information
                  contained therein as to which such counsel need express no
                  opinion) comply as to form in all material respects with the
                  applicable requirements of the Act and the rules thereunder;

                                    (2) the filing of the Registration Statement
                  and the execution and delivery of this Agreement have been
                  duly and validly authorized, and this Agreement has been duly
                  executed and delivered by the Company;

                                    (3) all contracts, agreements, instruments,
                  leases and licenses required to be described in the
                  Registration Statement or the Prospectuses have been so
                  described in all material respects. All contracts, agreements,
                  instruments, leases and licenses required to be filed as
                  exhibits to the Registration Statement have been so filed or
                  incorporated by reference therein;

                                    (4) neither the issuance and sale of the
                  Securities, the execution, delivery and performance by the
                  Company of this Agreement, nor the consummation of any other
                  of the transactions herein contemplated and the fulfillment of
                  the terms hereof (A) requires the consent, approval,
                  authorization, registration or qualification of or with any
                  governmental authority, except such as have been obtained
                  under the Act, and such as may be required under state
                  securities or Blue Sky laws, the laws of jurisdiction outside
                  the United States and the by-laws and rules of the NASD and,
                  if the Registration Statement is not effective under the Act
                  as of the Execution Time, such as may be required (and shall
                  be obtained as provided in this Agreement) under the Act, or
                  (B) results in a breach or violation of any of the terms and
                  conditions of, or constitute a default under, any indenture,
                  mortgage, deed of trust, lease, license or other agreement or
                  instrument described in the Registration Statement or the
                  Prospectuses or filed as an exhibit to the Registration
                  Statement and to which the Company or any of its Subsidiaries
                  is a party or by which the Company or any of its Subsidiaries
                  or any of their respective properties are bound, or the
                  charter documents or by-laws of the Company or any of its
                  Subsidiaries, or any U.S. statute, rule or

                  rules or regulations of the NASD with respect to which such
                  counsel expresses no opinion) known by such counsel to be
                  applicable to the Company or any of its Subsidiaries or any
                  judgment, decree or order of any court or other governmental
                  authority or any arbitrator known to such counsel to be
                  applicable to the Company or any of its Subsidiaries;

                                    (5) to the knowledge of such counsel and
                  except as set forth in the Prospectuses, there is not now
                  pending or threatened, any action, suit or proceeding to which
                  the Company or any of its Subsidiaries is a party before or by
                  any court or governmental agency or body (including without
                  limitation proceedings of the Commission pursuant to Section
                  8(b) of the Act) (except that such counsel need express no
                  opinion as to any state securities or Blue Sky authority)
                  that, if determined adversely to the Company or such
                  Subsidiary, is reasonably likely to result in any material
                  adverse change in the condition (financial or other),
                  business, properties, assets or results of operations of the
                  Company and its subsidiaries taken as a whole, or is
                  reasonably likely to affect the ability of the Company to
                  carry out its obligations hereunder;

                                    (6) the Company has been duly incorporated
                  and each of the Company and the Company's Subsidiaries is
                  validly existing as a corporation or other business entity in
                  good standing under the laws of the jurisdiction in which it
                  was chartered or organized, with full corporate power and
                  authority to own its properties and conduct its business as
                  described in the Registration Statement and the Prospectuses;
                  and each of the Company and its Subsidiaries is duly qualified
                  to do business as a foreign corporation and is in good
                  standing under the laws of each jurisdiction that requires
                  such qualification wherein it owns or leases properties or
                  conducts business and in which the failure, individually or in
                  the aggregate, to be so qualified could have a material
                  adverse effect on the condition (financial or other),
                  business, properties, assets or results of operations of the
                  Company and its Subsidiaries taken as a whole;

                                    (7) all of the outstanding shares of capital
                  stock of each of the Subsidiaries have been duly authorized
                  and validly issued and are fully paid and nonassessable, and
                  all the outstanding shares of capital stock of the
                  Subsidiaries (except in the case of CCC, of which the Company
                  only owns 49% of the outstanding capital stock) are held of
                  record by the Company or its other subsidiaries and, to the
                  knowledge of such counsel, are owned by the Company or its
                  other subsidiaries free and clear of any perfected security
                  interest and, to the knowledge of such counsel, any other
                  security interests, claims, liens or encumbrances except
                  restrictions imposed by the Act or applicable state securities
                  laws or, in the case of CCC, the CCC

                  Shareholders Agreement. To the knowledge of such counsel, such
                  shares of capital stock of the Subsidiaries have not been
                  issued in violation of any preemptive rights or, to the
                  knowledge of such counsel, other rights of first refusal. To
                  the knowledge of such counsel, no options, warrants or other
                  rights to purchase or otherwise acquire any authorized but
                  unissued shares of capital stock of any Subsidiary or any
                  security convertible into shares of such capital stock are now
                  outstanding and no shares of such capital stock have been
                  reserved for issuance;

                                    (8) the Company's authorized equity
                  capitalization is as set forth under the heading
                  "Capitalization" in the Prospectuses, as of the date set forth
                  therein, and as of the date hereof, and the outstanding shares
                  of Common Stock have been duly authorized and validly issued
                  and are fully paid and nonassessable. The Securities have been
                  duly authorized and, when issued and delivered to and paid for
                  by the International Underwriters pursuant to this Agreement
                  and by the U.S. Underwriters pursuant to the U.S. Underwriting
                  Agreement, will be validly issued (assuming the certificates
                  evidencing such Securities have been duly executed by the
                  Company's Transfer Agent, an assumption which such counsel
                  shall not be required to verify), fully paid and
                  nonassessable. Except pursuant to this Agreement or the U.S.
                  Underwriting Agreement and as set forth in the Prospectuses,
                  no options, warrants, preemptive rights or, to the knowledge
                  of such counsel, any other rights to purchase or otherwise
                  acquire any authorized but unissued shares of Common Stock of
                  the Company or any security convertible into shares of Common
                  Stock of the Company are now outstanding and no shares of
                  Common Stock have been reserved for issuance. To the knowledge
                  of such counsel, no shares of Common Stock are required
                  pursuant to any contract or other right to be included in the
                  Registration Statement, other than the shares held by William
                  J. Dore included therein;

                                    (9) to the knowledge of such counsel,
                  neither the Company nor any of its Subsidiaries is in breach
                  of any term or provision of its charter or by-laws and no
                  default exists (and no event has occurred that with notice or
                  lapse of time, or both, would constitute a default) in the due
                  performance and observance of any term, covenant or condition
                  of any indenture, mortgage, deed of trust, lease, note, bank
                  loan or credit agreement, license or any other agreement,
                  including without limitation any U.S. government ship
                  financing bonds, described in the Registration Statement or
                  the Prospectuses or filed as an exhibit to the Registration
                  Statement and to which the Company or any of its Subsidiaries
                  is a party or by which the Company or any of its Subsidiaries
                  or any of their respective properties may be bound, which
                  breach or default would have a material adverse effect on

                  the condition (financial or other), business, properties, 
                  assets or results of operations of the Company and its 
                  subsidiaries taken as a whole; and

                                    (10) the Company is not an "investment
                  company" within the meaning of the Investment Company Act of
                  1940, as amended.

                                    (11) The statements in the International
                  Prospectus under the caption "Certain United States Tax
                  Consequences to Non-United States Holders" constitute fair
                  summaries of the matters referred to therein.

In addition, such counsel shall state that such counsel has participated in
conferences with officers and other representatives of the Company,
representatives of the independent public accountants of the Company, the
Selling Shareholder and representatives of the International Underwriters at
which the contents of the Registration Statement and the Prospectuses were
discussed and, although such counsel is not passing upon and does not assume
responsibility for the accuracy, completeness or fairness of the statements
contained in the Registration Statement or the Prospectuses (except as and to
the extent stated in subparagraph (3) and the first sentence of subparagraph (8)
above), such counsel advises that, on the basis of the foregoing (relying as to
materiality to a large extent upon officers and other representatives of the
Company), no facts came to the attention of such counsel that have caused them
to believe that the Registration Statement or any amendment thereto at the time
such Registration Statement or amendment became effective and on the date
hereof, contained an untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading, or that the Prospectuses or any supplement thereto at the date of
such Prospectuses or such supplement, and at the date hereof as the case may be,
contained an untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading (it
being understood that such counsel need express no comment with respect to the
financial statements and schedules and other financial or statistical data
included or incorporated by reference in the Registration Statement or the
Prospectuses).

         In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws of any jurisdiction other than the State of
Texas and the United States or the Louisiana Business Corporation Law (the
"LBCL"), to the extent they deem proper and so specify in such opinion, upon the
opinion of other counsel of good standing whom they believe to be reliable and
who are satisfactory to counsel for the International Underwriters, and (B) as
to matters of fact, to the extent they deem proper, on certificates of
responsible officers of the Company and public officials.

                           (ii)     the opinion of Kerry Williams, general 
         counsel of the company dated the Closing Date to the effect that:

                                    (1) to the knowledge of such counsel, each
                  of the Company and its Subsidiaries possesses all consents,
                  certificates, approvals, authorizations, orders,
                  registrations, qualifications, licenses and permits of and
                  from all state and federal public, regulatory or governmental
                  agencies and bodies necessary to the ownership, leasing and
                  operation of its properties and the conduct of its business as
                  described in the Registration Statement and the Prospectuses,
                  except where the failure to obtain or maintain any such
                  consent, certificate, approval, authorization, order,
                  registration, qualification, license or permit would not have
                  a material adverse effect upon the condition (financial or
                  other), business, properties, assets or results of operations
                  of the Company and its Subsidiaries taken as a whole, and, to
                  the knowledge of such counsel, neither the Company nor any
                  such Subsidiary has received any notice of proceedings
                  relating to the revocation or modification of any such
                  consent, certificate, approval, authorization, order,
                  registration, qualification, license or permit that, singly or
                  in the aggregate, if the subject of an unfavorable decision,
                  ruling or finding, would result in a material adverse change
                  in the condition (financial or other), business, properties,
                  assets or results of operations of the Company and its
                  subsidiaries taken as a whole;

                                    (2) to the knowledge of such counsel, each
                  of the Company and its Subsidiaries (and the manner in which
                  each of them conducts its business or proposes to conduct its
                  business) is in material compliance with all laws, ordinances
                  or governmental rules or regulations to which it is subject,
                  including without limitation any rules or regulations of the
                  Minerals Management Service of the United States Department of
                  Interior, the United States Coast Guard and the Environmental
                  Protection Agency;

                                    (3) to the knowledge of such counsel, the
                  Company and its Subsidiaries have good and defensible title to
                  all of the real property, vessels and assets described as
                  owned by each of them in the Prospectuses, in each case free
                  and clear of any security interests, liens, encumbrances,
                  equities, claims and other defects, except (A) such as are
                  disclosed in the Prospectuses or do not materially and
                  adversely affect the value of such property, and (B) such as
                  do not interfere in any material respect with the use made or
                  proposed to be made of such property by the Company or such
                  Subsidiary; and to the knowledge of such counsel, any real
                  property and buildings held under any lease by the Company or
                  its Subsidiaries are held under leases that are valid,
                  existing and in full force and effect, except where the
                  failure to be valid, existing and in full force and effect
                  would not have a material adverse effect on the condition
                  (financial or other), business, properties, assets or results
                  of operations of the Company and its subsidiaries taken as a
                  whole; and

                                    (4) to the knowledge of such counsel, the
                  Company and its Subsidiaries own or have the right to use all
                  patents, licenses, sublicenses and rights thereof that are
                  described in the Prospectuses, except for those the absence of
                  which would not in the aggregate have a material adverse
                  effect on the condition (financial or other), business,
                  properties, assets or results of operations of the Company and
                  its subsidiaries taken as a whole, and, to the knowledge of
                  such counsel, no default exists (and no event has occurred
                  that with notice or lapse of time, or both, would constitute a
                  default) in the due performance of and observance of, and no
                  event has occurred (including in connection with the offering
                  of the Securities contemplated by this Agreement) that would
                  have a material adverse effect on the Company's or any such
                  Subsidiary's right to use the patented equipment and
                  technology currently used by the Company or any such
                  Subsidiary under any term, covenant or condition of any
                  license or sublicense to which the Company or any such
                  Subsidiary is a party.

         In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws of any jurisdiction other than the State of
Texas and the United States or the Louisiana Business Corporation Law (the
"LBCL"), to the extent they deem proper and so specify in such opinion, upon the
opinion of other counsel of good standing whom they believe to be reliable and
who are satisfactory to counsel for the International Underwriters, and (B) as
to matters of fact, to the extent they deem proper, on certificates of
responsible officers of the Company and public officials.

                  (c) In the event the option granted pursuant to Section 2(b)
is exercised, the Selling Shareholder shall have furnished to the International
Representatives the opinion of Vinson & Elkins L.L.P., counsel for the Selling
Shareholder, dated the Option Closing Date or, if the option granted pursuant to
Section 2(b) hereof has been exercised on or before the third business day prior
to the Closing Date, the Closing Date, to the effect that:

                           (i) this Agreement, the Custody Agreement and the
         Power of Attorney have been duly executed and delivered by the Selling
         Shareholder and are valid and binding on the Selling Shareholder, and
         the Selling Shareholder has full legal right and authority to sell,
         transfer and deliver in the manner provided in this Agreement the
         Securities being sold by the Selling Shareholder hereunder;

                           (ii) upon the delivery by the Selling Shareholder to
         the several International Underwriters of certificates for the
         International Option Securities being sold hereunder by the Selling
         Shareholder against payment therefor as provided herein, the
         International Underwriters (assuming they are bona fide purchasers
         within the meaning of the Uniform Commercial Code) will acquire good
         and marketable title to such International Option Securities, free and
         clear of all liens, encumbrances, equities and claims whatsoever;


                                      -24-

                           (iii) to the knowledge of such counsel, no consent,
         approval, authorization or order of any court or governmental agency or
         body is required for the consummation by the Selling Shareholder of the
         transactions contemplated herein, except such as may have been obtained
         under the Act and such as may be required under the state securities or
         Blue Sky laws of any jurisdiction or the by-laws of the NASD in
         connection with the purchase and distribution of the Securities by the
         International Underwriters and such other approvals (specified in such
         opinion) as have been obtained; and

                           (iv) neither the sale of the International Option
         Securities by the Selling Shareholder, the execution, delivery and
         performance by the Selling Shareholder of this Agreement, nor the
         consummation of any other of the transactions contemplated herein by
         the Selling Shareholder or the fulfillment of the terms hereof by the
         Selling Shareholder will result in a breach or violation of, or
         constitute a default under the terms of any indenture or other
         agreement or instrument known to such counsel and to which the Selling
         Shareholder is a party or bound, or any law, judgment, order or decree
         known to such counsel to be applicable to the Selling Shareholder of
         any court, regulatory body, administrative agency, governmental body or
         arbitrator having jurisdiction over the Selling Shareholder.

In rendering such opinion, such counsel may rely (A) as to matters involving the
application of laws of any jurisdiction other than the State of Texas and the
United States or under the LBCL, to the extent they deem proper and specified in
such opinion, upon the opinion of other counsel of good standing whom they
believe to be reliable and who are satisfactory to counsel for the International
Underwriters and (B) as to matters of fact, to the extent they deem proper, on
certificates of the Selling Shareholder and public officials.

                  (d) The International Representatives shall have received from
Jones, Walker, Waechter, Poitevent, Carrere & Denegre, L.L.P., counsel for the
International Underwriters such opinion or opinions, dated the Closing Date,
with respect to the issuance and sale of the International Securities, the
Registration Statement, the Prospectuses (together with any supplement thereto)
and other related matters as the International Representatives may reasonably
require, and the Company and the Selling Shareholder shall have furnished to
such counsel such documents as they request for the purpose of enabling them to
pass upon such matters.

                  (e) The Company shall have furnished to the International
Representatives a certificate of the Company, signed by the Chairman of the
Board or the President and the principal financial or accounting officer of the
Company, dated the Closing Date, to the effect that the signers of such
certificate have carefully examined the Registration Statement, the
Prospectuses, any supplements to the Prospectuses, this Agreement and the U.S.
Underwriting Agreement and that:

                           (i) the representations and warranties of the Company
         in this Agreement are true and correct in all material respects on and
         as of the Closing Date with the same effect as if made on the Closing
         Date and the Company has complied with all the agreements and satisfied
         all the conditions on its part to be performed or satisfied at or prior
         to the Closing Date;

                           (ii) no stop order suspending the effectiveness of
         the Registration Statement has been issued and no proceedings for that
         purpose have been instituted or, to the best knowledge of the Company,
         threatened; and

                           (iii) since the date of the most recent financial
         statements included in the Prospectuses (exclusive of any supplement
         thereto), there has been no material adverse change in the condition
         (financial or other), business, properties, assets, prospects or
         results of operations of the Company and its subsidiaries, whether or
         not arising from transactions in the ordinary course of business,
         except as set forth in or contemplated in the Prospectuses (exclusive
         of any supplement thereto).

                  (f) If the Option granted pursuant to Section 2(b) is
exercised, the Selling Shareholder shall have furnished to the International
Representatives a certificate, signed by the Selling Shareholder or an
Attorney-In-Fact, dated the Option Closing Date or, if the option granted by
Section 2(b) hereof has been exercised on or before the third business day prior
to the Closing Date, the Closing Date, to the effect that the signer of such
certificate has carefully examined the Registration Statement, the Prospectuses,
any supplement to the Prospectuses, this Agreement and the U.S. Underwriting
Agreement and that the representations and warranties of the Selling Shareholder
in this Agreement are true and correct in all material respects on and as of the
Option Closing Date or, if the option granted by Section 2(b) hereof has been
exercised on or before the third business day prior to the Closing Date, as of
the Closing Date, to the same effect as if made on the Option Closing Date, or
the Closing Date, as the case may be.

                  (g) At the Execution Time and at the Closing Date, Deloitte &
Touche LLP shall have furnished to the International Representatives letters,
dated respectively as of the Execution Time and as of the Closing Date, in form
and substance satisfactory to the International Representatives, confirming that
they are independent accountants within the meaning of the Act, the Exchange Act
and the respective applicable published rules and regulations thereunder and
stating in effect that:

                           (i) in their opinion (A) the audited consolidated
         financial statements and financial statement schedules of the Company
         included or incorporated in the Registration Statement and the
         Prospectuses and reported on by them comply as to form in all material
         respects with the applicable accounting requirements of the Act and the
         related published rules and regulations thereunder and constitute the
         only audited financial statements required to be included or


                                      -26-


<PAGE>   27



         incorporated therein; and (B) the pro forma financial information and
         the pro forma consolidated financial statements included or
         incorporated in the Registration Statement and the Prospectuses
         constitute the only pro forma information and pro forma statements
         required to be included or incorporated therein under the applicable
         accounting requirements of the Act and the related published rules and
         regulations.

                           (ii) on the basis of a reading of the latest
         unaudited consolidated financial statements made available by the
         Company; carrying out certain specified procedures (but not an
         examination in accordance with generally accepted auditing standards)
         which would not necessarily reveal matters of significance with respect
         to the comments set forth in such letter; a reading of the minutes of
         the meetings of the shareholders and directors of the Company and its
         Subsidiaries; and inquiries of certain officials of the Company and its
         Subsidiaries who have responsibility for financial and accounting
         matters of the Company and its Subsidiaries as to transactions and
         events subsequent to March 31, 1996, nothing came to their attention
         that caused them to believe that:

                                    (1) any unaudited financial statements
                  included or incorporated in the Registration Statement and the
                  Prospectuses do not comply in form in all material respects
                  with applicable accounting requirements and with the published
                  rules and regulations of the Commission with respect to
                  financial statements included or incorporated in quarterly
                  reports on Form 10-Q under the Exchange Act; and said
                  unaudited financial statements are not in conformity with
                  generally accepted accounting principles applied on a basis
                  substantially consistent with that of the audited financial
                  statements included or incorporated in the Registration
                  Statement and the Prospectuses;

                                    (2) with respect to the period subsequent to
                  March 31, 1996, there were any changes, at a specified date
                  not more than five business days prior to the date of each
                  such letter, in the consolidated long-term debt, less current
                  maturities, of the Company or capital stock of the Company,
                  and as of the date of the latest available month-end
                  consolidated financial statements, there were any decreases in
                  the consolidated shareholders' equity of the Company, or
                  decreases in consolidated receivables of the Company as
                  compared with the amounts shown on the March 31, 1996
                  consolidated balance sheet included or incorporated in the
                  Registration Statement and the Prospectuses, or for the period
                  from March 31, 1996 to the date of the latest available
                  month-end consolidated financial statements there were any
                  decreases, as compared with the corresponding period in the
                  preceding year, in consolidated contract revenues,
                  consolidated income before income taxes or in total or per
                  share amounts of consolidated net income of the Company,
                  except in all instances for changes or decreases

                  set forth in such letter, in which case the letter shall be
                  accompanied by an explanation by the Company as to the
                  significance thereof unless such explanation is not deemed
                  necessary by the International Representatives; or

                                    (3) any unaudited amounts of contract
                  revenues, net income and net income per average common share
                  included under the heading "Recent Developments" in the
                  Registration Statement and the Prospectuses do not agree with
                  the amounts set forth in the unaudited financial statements
                  for the same periods or were not determined on a basis
                  consistent with that of the corresponding amounts in the
                  audited financial statements included or incorporated in the
                  Registration Statement and the Prospectuses; and

                           (iii) they have performed certain other specified
         procedures as a result of which they determined that certain
         information of an accounting, financial or statistical nature (which is
         limited to accounting, financial or statistical information derived
         from the general accounting records of the Company and its
         Subsidiaries) set forth in the Registration Statement and the
         Prospectuses, including without limitation the information set forth
         under the captions "Prospectus Summary" and "Selected Financial Data"
         and the information included in the "Management's Discussion and
         Analysis of Financial Condition and Results of Operations" in the
         Prospectuses, the information included or incorporated in Items 1, 2,
         6, 7 and 11 of the Company's Annual Report on Form 10-K, incorporated
         in the Registration Statement and the Prospectuses, and the information
         included in the "Management's Discussion and Analysis of Financial
         Condition and Results of Operations" included or incorporated in the
         Company's Quarterly Report on Form 10-Q, incorporated in the
         Registration Statement and Prospectuses agree with the accounting
         records of the Company and its Subsidiaries, excluding any questions of
         legal interpretation.

                           (iv) On the basis of a reading of the unaudited pro
         forma consolidated financial statements included in the Registration
         Statement and Prospectuses, carrying out certain specified procedures;
         inquiries of certain officials of the Company and its Subsidiaries who
         have responsibility for financial and accounting matters; and proving
         the arithmetic accuracy of the application of the pro forma adjustments
         to the historical amounts in the pro forma financial statements,
         nothing came to their attention that caused them to believe that the
         pro forma consolidated financial statements do not comply as to form in
         all material respects with the applicable accounting requirements of
         Rule 11-02 of Regulation S-X or that the pro forma adjustments have not
         been properly applied to the historical amounts in the compilation of
         such statements.

<PAGE>   29



         References to the Prospectuses in this paragraph (g) include any
supplement thereto at the date of the letter.

                  (h) Subsequent to the Execution Time or, if earlier, the dates
as of which information is given in the Registration Statement (exclusive of any
amendment thereof) and the Prospectuses (exclusive of any supplement thereto),
there shall not have been (i) any change or decrease specified in the letters
referred to in paragraph (g) of this Section 6 or (ii) any change, or any
development involving a prospective change, in or affecting the business or
properties of the Company and its subsidiaries the effect of which, in any case
referred to in clause (i) or (ii) above, is, in the judgment of the
International Representatives, so material and adverse as to make it impractical
or inadvisable to proceed with the offering or delivery of the Securities as
contemplated by the Registration Statement (exclusive of any amendment thereof)
and the Prospectuses (exclusive of any supplement thereto).

                  (i) Prior to the Closing Date, the Company shall have
furnished to the International Representatives such further information,
certificates and documents as the International Representatives may reasonably
request.


                  (j)      The closing of the purchase of the U.S. Securities 
to be issued and sold by the Company pursuant to the U.S. Underwriting 
Agreement shall occur concurrently with the closing described herein.

         If any of the conditions specified in this Section 6 shall not have
been fulfilled in all material respects when and as provided in this Agreement,
or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to the International Representatives and counsel for the
International Underwriters, this Agreement and all obligations of the
International Underwriters hereunder may be canceled at, or at any time prior
to, the Closing Date by the International Representatives. Notice of such
cancellation shall be given to the Company and the Selling Shareholder in
writing or by telephone or telegraph confirmed in writing.

         7.       Reimbursement of International Underwriters' Expenses.  If 
the sale of the Securities provided for herein is not consummated because any
condition to the obligations of the International Underwriters set forth in
Section 6 hereof is not satisfied, because of any termination pursuant to
Section 10 hereof or because of any refusal, inability or failure on the part of
the Company or the Selling Shareholder to perform any agreement herein or comply
with any provision hereof other than by reason of a default by any of the
International Underwriters, the Company will reimburse the International
Underwriters severally upon demand for all out-of-pocket expenses (including
reasonable fees and disbursements of counsel) that shall have been incurred by
them in connection with the proposed purchase and sale of the Securities. If the
Company is required to make any

                                      -29-


<PAGE>   30



payments to the International Underwriters under this Section 7 because of the
Selling Shareholder's refusal, inability or failure to satisfy any condition to
the obligations of the International Underwriters set forth in Section 6, the
Selling Shareholder shall reimburse the Company on demand for all amounts so
paid.

         8. Indemnification and Contribution. (a) The Company and the Selling
Shareholder jointly and severally agree to indemnify and hold harmless each
International Underwriter, the directors, officers, employees and agents of each
International Underwriter and each person who controls any International
Underwriter within the meaning of either the Act or the Exchange Act, against
any and all losses, claims, damages or liabilities, joint or several, to which
they or any of them may become subject under the Act, the Exchange Act or other
federal or state statutory law or regulation, at common law 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 a material fact contained in the Registration Statement for the
registration of the Securities as originally filed or in any amendment thereof,
or in any International Preliminary Prospectus or in either of the Prospectuses,
or in any amendment thereof or supplement thereto, 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 agree to reimburse each such indemnified party, as incurred, for any legal
or other expenses reasonably incurred by them in connection with investigating
or defending any such loss, claim, damage, liability or action; provided,
however, that the Company and the Selling Shareholder 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 any such untrue statement or alleged untrue statement or
omission or alleged omission made therein in reliance upon and in conformity
with written information furnished to the Company by or on behalf of any
International Underwriter through the International Representatives specifically
for inclusion therein; and further provided, that such indemnity with respect to
any International Preliminary Prospectus shall not inure to the benefit of an
International Underwriter (or any person controlling an International
Underwriter) from whom the person asserting any such loss, claim, damage or
liability purchased the Securities that are the subject thereof, if such person
did not receive a copy of the International Prospectus (or the International
Prospectus, as amended or supplemented) at or prior to the written confirmation
of the sale of such Securities to such person where such delivery of the
International Prospectus (or the International Prospectus, as amended or
supplemented) is required by the Act, unless such failure to deliver was a
result of the Company's failure to deliver the International Prospectus in
accordance with Section 5(a)(iv) of this Agreement, and if the untrue statement
or omission of a material fact contained in such International Preliminary
Prospectus was corrected in the International Prospectus (or the International
Prospectus, as amended or supplemented). This indemnity agreement will be in
addition to any liability which the Company or the Selling Shareholder may
otherwise have. Notwithstanding the provisions of this Section 8(a), the Selling
Shareholder shall not be liable under this Section 8(a) in an amount exceeding
the


                                      -30-


<PAGE>   31



product of the purchase price as set forth in Section 2 hereof and the number of
shares sold by the Selling Shareholder.

                  (b) Each International Underwriter severally agrees to
indemnify and hold harmless the Company, each of its directors, each of its
officers who signs the Registration Statement, and each person who controls the
Company within the meaning of either the Act or the Exchange Act and the Selling
Shareholder, to the same extent as the foregoing indemnity to each International
Underwriter, but only with reference to written information relating to such
International Underwriter furnished to the Company by or on behalf of such
International Underwriter through the International Representatives specifically
for inclusion in the documents referred to in the foregoing indemnity. This
indemnity agreement will be in addition to any liability which any International
Underwriters may otherwise have. The Company and the Selling Shareholder
acknowledge that the statements set forth in the last paragraph of the cover
page and under the heading "Underwriting" in any U.S. or International
Preliminary Prospectus and the Prospectuses constitute the only information
furnished in writing by or on behalf of the several International Underwriters
for inclusion in any U.S. or International Preliminary Prospectus or the
Prospectuses, and you, as the International Representatives, confirm that such
statements are correct.

                  (c) Promptly after receipt by an indemnified party under this
Section 8 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 this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless and
to the extent it did not otherwise learn of such action and such failure results
in the forfeiture by the indemnifying party of substantial rights and defenses
and (ii) will not, in any event, relieve the indemnifying party from any
obligations to any indemnified party other than the indemnification obligation
provided in paragraph (a) or (b) above. The indemnifying party shall be entitled
to appoint counsel of the indemnifying party's choice at the indemnifying
party's expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be satisfactory to the indemnified
party. Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel if (i) the use of counsel chosen by the indemnifying party to
represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent


                                      -31-


<PAGE>   32



the indemnified party within a reasonable time after notice of the institution
of such action or (iv) the indemnifying party shall authorize the indemnified
party to employ separate counsel at the expense of the indemnifying party. An
indemnifying party will not, without the prior written consent of the
indemnified party or parties, settle or compromise or consent to the entry of
any judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified party or parties are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding.

                  (d) In the event that the indemnity provided in paragraph (a)
or (b) of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, except as a result of the limitations of the
Selling Shareholder's indemnification liability provided by Section 8(a) hereof,
the Company and the Selling Shareholder, jointly and severally, and the
International Underwriters agree to contribute to the aggregate losses, claims,
damages and liabilities (including legal or other expenses reasonably incurred
in connection with investigating or defending same) (collectively "Losses") to
which the Company, the Selling Shareholder and one or more of the International
Underwriters may be subject in such proportion as is appropriate to reflect the
relative benefits received by the Company and the Selling Shareholder, on the
one hand, and by the International Underwriters, on the other, from the offering
of the Securities; provided, however, that in no case shall any International
Underwriter (except as may be provided in any agreement among underwriters
relating to the offering of the Securities) be responsible for any amount in
excess of the underwriting discount or commission applicable to the Securities
purchased by such International Underwriter hereunder, and further provided,
that in no case shall the Selling Shareholder be responsible for any amount in
excess of the limit set forth in paragraph (a) above. If the allocation provided
by the immediately preceding sentence is unavailable for any reason, the Company
and the Selling Shareholder, jointly and severally, and the International
Underwriters shall contribute in such proportion as is appropriate to reflect
not only such relative benefits but also the relative fault of the Company and
the Selling Shareholder, on the one hand, and of the International Underwriters,
on the other, in connection with the statements or omissions which resulted in
such Losses, as well as any other relevant equitable considerations; provided,
however, that in no case shall the Selling Shareholder be responsible for any
amount in excess of the limit set forth in paragraphs (a) above, respectively.
Benefits received by the Company and the Selling Shareholder shall be deemed to
be equal to the total net proceeds from the offering (before deducting
expenses), and benefits received by the International Underwriters shall be
deemed to be equal to the total underwriting discounts and commissions, in each
case as set forth on the cover page of the International Prospectus. Relative
fault shall be determined by reference to whether any alleged untrue statement
or omission relates to information provided by the Company, the Selling
Shareholder or the International Underwriters. The Company, the Selling
Shareholder and the International Underwriters agree that it would not be just
and

equitable if contribution were determined by pro rata allocation or any other
method of allocation that does not take account of the equitable considerations
referred to above. Notwithstanding the provisions of this paragraph (d), 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. For purposes of this Section 8,
each person who controls an International Underwriter within the meaning of
either the Act or the Exchange Act and each director, officer, employee and
agent of an International Underwriter shall have the same rights to contribution
as such International Underwriter; each person who controls the Company within
the meaning of either the Act or the Exchange Act, each officer of the Company
who shall have signed the Registration Statement and each director of the
Company shall have the same rights to contribution as the Company; and each
agent of the Selling Shareholder shall have the same rights to contribution as
the Selling Shareholder, subject in each case to the applicable terms and
conditions of this paragraph (d).

         9. Default by an International Underwriter. If any one or more
International Underwriters shall fail to purchase and pay for any of the
Securities agreed to be purchased by such International Underwriter or
International Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining International Underwriters shall be obligated severally
to take up and pay for (in the respective proportions that the amount of
International Securities set forth opposite their names in Schedule I hereto
bears to the aggregate amount of International Securities set forth opposite the
names of all the remaining International Underwriters) the Securities which the
defaulting International Underwriter or International Underwriters agreed but
failed to purchase; provided, however, that in the event that the aggregate
amount of International Securities which the defaulting International
Underwriter or International Underwriters agreed but failed to purchase shall
exceed 10% of the aggregate amount of International Securities set forth in
Schedule I hereto, the remaining International Underwriters shall have the right
to purchase all, but shall not be under any obligation to purchase any, of the
International Securities, and if such nondefaulting International Underwriters
do not purchase all the International Securities, this Agreement will terminate
without liability on the part of any nondefaulting International Underwriter the
Selling Shareholder or the Company. In the event of a default by any
International Underwriter as set forth in this Section 9, the Closing Date shall
be postponed for such period, not exceeding seven days, as the International
Representatives shall determine in order that the required changes in the
Registration Statement and the International Prospectus or in any other
documents or arrangements may be effected. Nothing contained in this Agreement
shall relieve any defaulting International Underwriter of its liability, if any,
to the Company, the Selling Shareholder and any nondefaulting International
Underwriter for damages occasioned by its default hereunder.

         10.      Termination.  This Agreement shall be subject to termination 
in the absolute discretion of the International Representatives, by notice 
given to the Company and the Selling Shareholder prior to delivery of and 
payment for the Securities, if prior to such time

Exchange or the National Association of Securities Dealers Automated Quotation
National Market System shall have been suspended or limited or minimum prices

make it, in the judgment of the International Representatives, impracticable or
inadvisable to proceed with the offering or delivery of the International
Securities as contemplated by the International Prospectus (exclusive of any
supplement thereto).

         11. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers, of the Selling Shareholder and of the International
Underwriters set forth in or made pursuant to this Agreement will remain in full
force and effect, regardless of any investigation made by or on behalf of any
International Underwriter, the Selling Shareholder or the Company or any of the
officers, directors or controlling persons referred to in Section 8 hereof, and
will survive delivery of and payment for the International Securities. The
provisions of Sections 7 and 8 hereof shall survive the termination or
cancellation of this Agreement.

and no other person will have any right or obligation hereunder.

Global Industries, Ltd.
107 Global Circle
Lafayette, Louisiana 70503

Gentlemen:

         As set forth in the Registration Statement on Form S-3 as amended to
the date hereof (File No. 333-18773) (the "Registration Statement"), filed by
Global Industries, Ltd., a Louisiana corporation (the "Company"), under the
Securities Act of 1933, as amended (the "Act"), relating to the sale of up to
8,050,000 shares of the Company's Common Stock, par value $0.01 per share (the
"Shares"), certain legal matters in connection with the Shares are being passed
upon for you by us.  At your request, this opinion is being furnished to you
for filing as Exhibit 5.1 to the Registration Statement and any registration
statement filed pursuant to Rule 462 (the "Rule 462 Registration Statement") to
register additional shares of Common Stock in accordance with such rule (the
"Additional Shares").

         We have acted as counsel for the Company in connection with the
registration of the Shares and if applicable, the Additional Shares under the
Act.  In connection therewith, we have examined such certificates, instruments
and documents and reviewed such questions of law as we have considered
necessary or appropriate for the purposes of this opinion.

         Based upon the foregoing examination and review, we are of the opinion
that the Shares and the Additional Shares have been duly authorized for
issuance and, when the Registration Statement with respect to the Shares and
the Rule 462 Registration Statement with respect to the Additional Shares, if
applicable, have been declared effective, and the Shares and the Additional 
Shares, if applicable, are issued in accordance with the provisions of the U.S.
Underwriting Agreement and International Underwriting Agreement (each as
defined in the Registration Statement), such Shares and the Additional Shares
will be validly issued (assuming the certificates evidencing such Shares and
the Additional Shares have been duly executed by the Company transfer agent),
fully paid and nonassessable.

         In rendering this opinion we have relied, as to factual matters, on
certificates of certain public officials and officers of the Company.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and the Rule 462 Registration Statement, if applicable,
and to the references to us under the caption "Legal Matters" in the
Prospectuses forming a part of the Registration Statement and the Rule 462
Registration Statement, if applicable.  In giving this consent, we do not
hereby admit that we are within the category of persons whose consent is
required under Section 7 of the Act and the rules and regulations of the
Securities and Exchange Commission thereunder.

                                        Very truly yours,





                                        VINSON & ELKINS L.L.P.
