                           (c) As of December 31, 1998, no Group Company had any
material liability or obligation (including without limitation in respect of any
borrowings), contingent or otherwise, that was required to be disclosed in the
Financial Statements in accordance with French GAAP, and that was not so

Financial Statements and which is required to be disclosed either in the
accounts or in the notes to the June 30 Financial Statements in accordance with
French GAAP.

                           (d) During the period from June 30, 1999 to the date

                  part or has become due or is liable to be declared due by
                  reason of either service of a notice or lapse of time or

                  Company;

                                                                              9.


                                    (iii) has entered into a contract or a
                  variation order or contract amendment involving capital
                  expenditure in an amount exceeding US$1,000,000 or its
                  equivalent in any other currency or other contracts involving
                  capital expenditure in the aggregate exceeding US$1,000,000;

                                    (iv) has paid or has agreed to pay any bonus
                  or profit sharing distributions of any kind to directors or
                  senior officers, except in the ordinary course of business
                  consistent with past practice, or as set forth in EXHIBIT
                  3.7(D); or

                                    (v) to the best of the Seller's knowledge,
                  has incurred any material liability or obligation outside the
                  ordinary course of business, contingent or otherwise, that
                  would be required to be disclosed if the Company were to
                  prepare a consolidated balance sheet and related notes as of
                  the date hereof in accordance with French GAAP, applied on a
                  basis consistent with the June 30 Financial Statements.

                           (e) Since June 30, 1999, except as set forth in
EXHIBIT 3.7(E), the Group Companies have conducted their operations in the
ordinary and usual course in substantially the same manner as such operations
have previously been conducted; PROVIDED, HOWEVER, that pursuant to this SECTION
3.7(E), the Seller does not make any representation relating to the terms of new
contracts or bids for new contracts, or the ongoing management of issues arising
under outstanding contracts.

Financial Statements utilize principles of revenue recognition for long term
projects and include provisions for operational risks and charges with respect
to the Group Companies, which in each case have been established in accordance
with French GAAP applied on a consistent basis except as set forth in the
Financial Statements. The recognition of revenues and provisions in respect of
long term projects in the June 30 Financial Statements have been established on
the basis of the quarterly project status reports of ETPM as of June 30, 1999,
copies of which were made available to the Purchaser.

                           (g) The Purchaser acknowledges that (i) it has been
given access to the long term client Material Contracts of the Group Companies
and (ii) it recognizes the subjective nature of financial projections and
provisioning policies on long term contracts. Accordingly, notwithstanding
anything to the contrary set forth in this Agreement, the Seller makes no
representation and gives no warranty with respect to revenue and cost
recognition and provisions in respect of long-term contracts, other than that
they have been established in accordance with French GAAP applied on a
consistent basis (with respect to the French Financial Statements) or in
accordance with US GAAP applied on a consistent basis except as set forth
therein (with respect to the US Financial Statements).

obligations outstanding thereunder). As of the date hereof, except as set forth
in EXHIBIT 3.7(H), there are no outstanding liabilities of the Seller to any of
the Group Companies. The Seller agrees that the 0% rate loan agreement which was
entered into between itself and the Company on July 30, 1999 in relation to the
"Spring" program for employees shall not be immediately repayable by virtue of
the transfer of the Shares, but shall be repayable by the Company according to
the normal repayment schedule set forth in article 3 of such loan agreement. The
Seller further represents and warrants that (i) pursuant to the Spring program,
the Company is not required to make any cash advance at any time to the Seller
since the Company is required to repay in part the loan only at the time and
where the employees pay to it the corresponding sums, (ii) any employee of any
Group Company whose employment contract is terminated shall have to repay
immediately and in full his or her debt vis a vis its employer in relation to
the Spring program, and (iii) no employee of any Group Company has or will have
any claims against any Group Company with respect to this Spring Program for
matters arising prior to the First Closing Date, or as a result of the transfer
of Shares contemplated hereunder.

                           (i) Except as set forth in EXHIBIT 3.7(I) none of the
Group Companies has purchased or disposed of (i) any business since January 1,
1999, or (ii) any business for an amount in excess of US$ 1,000,000 during 1997
or 1998, and none of the Group Companies has any commitment to make such
acquisition or disposal in the future.

                           (j) Set forth in EXHIBIT 3.7(J) is a list of all
interest and/or currency hedging operations and all swaps and similar financial
arrangements to which any of the Group Companies was a party as of November 30,
1999.

Statements are properly reflected in the books and records of the Group
Companies.

                           (l) There are no material differences between the
carrying value of the investment in each unconsolidated subsidiary included in
the Group Companies and the Group Companies' proportionate share of the
underlying equity of such entity.

                  3.8      MOVABLE PROPERTY AND BUSINESSES ("FONDS DE COMMERCE")
                           AND NON MOVABLE PROPERTY

the ordinary course of business) and as now conducted and the consummation of

Company has received any notice of a threatened termination of any such coverage
(other than a normal renewal notice), including as a result of the contemplated
transaction.

                                    (b) EXHIBIT 3.11(II)(B) describes: (i) any
self-insurance arrangement by or affecting any of the Group Companies, including
any reserves established thereunder; (ii) any contract or arrangement, other
than a policy of insurance, for the transfer or sharing of any risk by any of
the Group Companies; and (iii) all obligations of the Group Companies to third
parties with respect to insurance under customer contracts and lease agreements
and identifies the policy under which such coverage is provided.

                                    (c) The Group Companies maintain insurance
against risks of the kind and in amounts that are customary for businesses
similarly situated.

                                    (d) In EXHIBIT 3.11(II)(D) is a complete
list of all processed insurance claims which have been reported as Quarterly
Insurance Status reports at September 30, 1999 and consequently attached to
Arcus Quarterly Status Reports (AQSR), plus subsequent occurrences or claims,
occurred or received since issuance of said documentation.

                                    (i) leases or other contracts entered into

                  leases or contracts entered into after July 8, 1999) in the
                  aggregate (it being understood that individual purchase orders
                  placed in the ordinary course of business shall not be
                  considered "contracts" for this purpose, although master
                  agreements covering multiple purchase orders shall be
                  considered "contracts");

                                    (ii) contracts under which the Group
                  Companies are forecast to receive revenues in any years (other

                  any of the Group Companies (other than the constitutive
                  documents of the entities listed in EXHIBIT 3.4(B)) or its or
                  their officers or directors, or members of their respective

                  respect to any of the present and/or future business
                  activities of any Group Company;

                                    (vii) any collective bargaining or similar

                  Companies entered into prior to July 8, 1999, or implementing
                  French legal requirements imposing a 35-hour work week; and

                                    (viii) any power of attorney currently
                  effective (other than powers of attorney held by employees of
                  the Group Companies) granted prior to July 8, 1999.

                           (b) Except as set forth in EXHIBIT 3.12(B), none of
the Group Companies is in default under any of the Material Contracts as a

Material Contract before the stated expiration of its term or which could
reasonably be expected to result in material damages; no Group Company has
notified the other party to any Material Contract in writing of a material
breach of such other party's obligations thereunder; and the Seller has not
received written notice of existing circumstances likely to give rise to a
default by any Group Company or by the other parties under any such Material
Contract such as to constitute grounds for the invalidity, avoidance or
repudiation of such Material Contract. Each Material Contract is in full force
and effect and true and correct copies thereof have been made available to the
Purchaser. Except as set forth in EXHIBIT 3.12(B), no Group Company is a party
to or subject to any agreement, obligation or liability which is a guarantee or
an indemnity by any such Group Company in respect of the obligations of a third
party which is not a Group Company under which any liability or contingent
liability is outstanding.

                           (c) No Group Company is a party to any agreement
which can be terminated or which would be breached by the consummation of the
transactions contemplated herein.

                           (d) Except as expressly set forth above, the Seller
makes no representation and gives no warranty with respect to the Material
Contracts. Without limiting the generality of the foregoing and without limiting
in any way the provisions of Section 3.7, the Seller makes no representation and
gives no warranty as to the profitability (present or future) of any of the
contracts of the Group Companies, including without limitation those described
in subsection (a)(ii).

                           (e) Set forth in EXHIBIT 3.12(E) is a list of all
contracts to which any of the Group Companies is a party which contain
provisions providing for non-compete and/or exclusivity arrangements.

                           (f) Except as contemplated with the Purchaser under
the terms of this Agreement, neither the Seller nor any of the Seller's
affiliates are bound under or a party to any contract or other agreement (i)
regarding the consolidation or merger of any of the Group Companies with or into
any such person or persons (ii) regarding the sale, conveyance or disposition of
all or substantially all or a large portion of the assets of any of the Group
Companies or a transaction or series of related transactions in which any voting
securities of any the Group Companies would be issued, transferred or disposed
of, or (iii) regarding any other form of acquisition, liquidation, dissolution
or winding up of any of the Group Companies.

                           (g) The Share Purchase Agreement dated August 2, 1999
between the Seller and Global Industries Ltd. is the only agreement with
continuing obligations relating to the subject matter thereof.

                  3.13     NO LEGAL PROCEEDINGS

                           (a) Except as indicated in EXHIBIT 3.13(A), there are
no judicial, administrative or arbitration proceedings pending or, to the best
of the Seller's knowledge, overtly threatened against any of the Group
Companies, which, if determined adversely with respect to such Group Company,
would result in a liability in an amount exceeding (i) US$200,000 relating to
proceedings pending prior to July 8, 1999 and (ii) US$500,000 relating to
proceedings which became pending afterwards, or the equivalent in any other
currency or would have a material adverse effect on the Group Companies taken as
a whole.

                           (b) Except as indicated in EXHIBIT 3.13(B), during
the period of one year preceding the date of this Agreement, there has been no
official inquiry, investigation or disciplinary proceeding with respect to any
Group Company (other than of a routine nature) by any governmental authority,
agency, tribunal or administrative body with jurisdiction over such Group
Company (collectively, a "COMPETENT AUTHORITY"); provided, however, that the
Seller's representation in this Section 3.13(b) is made to the best of the
Seller's knowledge with respect

<PAGE>
                                                                             19.

Companies (other than the Company) arising after July 8, 1999.

                  The Group Companies' activities are in all material respects
carried out in compliance with the permits and consents required for the
performance of their activities and with all legislation and regulations which
are presently applicable to them. To the best of the Seller's knowledge, none of
the material assets of the Group Companies have been used in such a manner as a
result of which a Competent Authority is likely to require that any Group
Company cease using any such asset in its business. There is no order, decree or
judgment of any Competent Authority outstanding against any Group Company, which
may have a materially adverse effect upon the assets or business of the Group
Companies as a whole.

                  3.15     LICENSES

                           (a) The Group Companies (i) own, or lawfully use in

authorizations or registrations of governmental or administrative bodies
(collectively, "LICENSES") which are necessary for the Group Companies to
conduct their businesses as now conducted and (ii) all such Licenses are in full
force and effect, and the Group Companies are in compliance with their
obligations under such Licenses in all material respects.

                           (b) There are no proceedings of any nature pending
or, to the best of the Seller's knowledge, threatened against any of the Group
Companies in which any third party has requested or has stated that it will
request the withdrawal, suspension or modification of any of the Licenses owned
or used by the Group Companies. No Group Company has received notice from any
Competent Authority relating to the suspension or cancellation, or threat
thereof, of any material License.

                  3.16     ENVIRONMENT

                  Except as indicated in EXHIBIT 3.16, the Group Companies carry
out their activities in compliance in all materials respects with environmental
legislation and regulations currently applicable to them. In particular, the
Group Companies have obtained and currently hold all environmental Licenses or,
where applicable, have filed necessary declarations with the relevant
authorities, required for the performance of their activities, and the Group
Companies are complying in all material respects with such Licenses.

                                                                             20.


                  Except as disclosed on EXHIBIT 3.16, (i) there is no physical
condition existing on any property now or previously owned or operated by any of
the Group Companies (nor are there any physical conditions existing on any other
property that may have been impacted by the operations of the Group Companies)
and (ii) the Group Companies have not handled or disposed of any substance,
arranged for disposal of any substance, exposed any employee or other person to
any substance or condition or operated any facility in any manner in any case
which could reasonably be expected to give rise to any remedial obligation under
environmental, health or safety laws or which could result in any liability for
the Group Companies to any third person claiming damage to persons, property or
natural resources.

                  3.17     LABOR MATTERS

                           (a) Except as described in EXHIBIT 3.17(A), no Group
Company maintains any compensation, bonus, profit-sharing, pension, retirement,
stock option or purchase, severance pay, life, health, medical, disability or
accident insurance, vacation or other employee benefit plan or program (a
"PLAN") in excess of the employee profit participations required by applicable
law in the jurisdictions in which the Group Companies operate. The Group
Companies are in compliance in all material respects with all the Plans, and
such Plans are in material compliance with all applicable laws and regulations.

                           (b) Except as indicated in EXHIBIT 3.17(B), none of
the Group Companies has concluded any contracts with any of its employees which
provide, in the event of termination, for a notice period or payment of an
indemnity which exceeds that provided for by applicable legislation, regulations
and collective bargaining agreements.

                           (c) Except as set forth in EXHIBIT 3.17(C), no breach
of contract and/or denial of fair representation (DELIT D'ENTRAVE) claim has
been filed or is pending against any of the Group Companies and/or any labor
organization representing employees of any of the Group Companies; no citation
has been issued by any labor inspector or other authority responsible for the
supervision of compliance with labor related rules against any of the Group
Companies and no notice of contest or enforcement proceeding involving any of
the Group Companies has been filed or is pending.

                           (d) Except as set forth in EXHIBIT 3.17(D), there
have not occurred any strikes, work stoppages or other similar labor actions by
any group of employees of any of the Group Companies during the two-year period
preceding the date of this Agreement.

                           (e) All of the permanent or part-time employees of
the Group Companies are employed under valid and enforceable contracts which
conform with applicable laws and regulations.

                           (f) Except as set forth in EXHIBIT 3.17(F), no
employees of the Group Companies or persons representing the interests of such
employees have ever made claims to any administrative (including the social
security office) or judicial authorities, to be compensated for the harm they
suffered as a result of an asbestos-related illness recognized as an
occupational

                                                                             21.


illness within the meaning of the French Social Security Code and no allegation
of inexcusable fault which may allegedly have been committed by the Group
Companies has either been made by such employees (or persons representing their
interests) or upheld by the competent administrative or judicial authorities
(including the social security tribunal).

                           (g) The workers representation committee ("COMITE
D'ENTREPRISE") of the Company has been informed of the sale of the Company, has
been provided with all required information and has been consulted on the offer
made by the Purchaser, all in accordance with the French labor law.

                  3.18     INTERMEDIARIES

                  Neither the Seller nor any of the Group Companies has
concluded any agreements with any intermediaries or advisors whatsoever which
would bind one of the Group Companies to pay, either directly or indirectly, any
remuneration, commissions or fees as a result of the signature of this Agreement
or the performance of the operations contemplated herein and/or in any of the
other Transaction Documents.

                  3.19     INTEREST IN CLIENTS AND SUPPLIERS,  PAYMENTS OF FEES
                           AND COMMISSIONS

                  To the best of the Seller's knowledge, neither any officer nor
any executive director of any Group Company possesses, directly or indirectly,
any material financial interest in, or is a director, officer or employee of any
corporation, firm, association or business organization which is a client,
supplier, customer, lessor, lessee or competitor or potential competitor of any
Group Company. For purposes of the foregoing, the ownership of shares of a
publicly listed company amounting to less than 1% of the capital of such company
shall not be considered a "material financial interest." The provisions of the
1997 OECD Convention on combating bribery of foreign public officials in
international business transactions have been incorporated in the standard form
of agent agreement used by the Group Companies.

subsidiaries as a result of actual or contingent reimbursement obligations in
respect of research and development grants was FF 2.4 million for the year ended
December 31, 1997 and of the same order of magnitude for the year ended December
31, 1998. All such reimbursement obligations are based on the proceeds from the
use of the results of the research and development funded by such grants. None
of the Group Companies will be required, as a result of the consummation of the
transactions contemplated in this Agreement, to repay to the Seller or any
French or other government or agency any subsidies or grants made to any of the
Group Companies, either directly or through the Seller, so long as the Group
Companies continue their research and development funded with such subsidies and
grants in a manner consistent with past practice.

                                                                             22.

meeting convened for the winding-up of any Group Company, nor has any distress
or execution of other process has levied against any Group Company or action
taken to repossess goods in any Group Company's possession. None of the Group
Companies incorporated in France is subject to any judicial measures of Law No.
84 - 148 of March 1, 1984 or No. 85 - 18 of January 25, 1985 (as amended) such

proceedings (REDRESSEMENT JUDICIAIRE or LIQUIDATION JUDICIAIRE or REGLEMENT

1244-1 of the French Civil Code.

                           (b) As of the date hereof, no receiver (including any
administrative receiver or receiver and/or manager), trustee or administrator
has been appointed of the whole or any part of the assets or undertakings of any
Group Company, and the Seller is not aware of any circumstances likely to give
rise to the appointment of any such receiver, trustee or administrator. No
petition has been presented for an administration order in respect of any Group
Company.

                  3.22     DISCLOSURE

none of the Purchaser Group Companies

                                                                             26.

not for a period of 5 years from First Closing Date engage, directly or
indirectly, in activities of the type currently conducted by any Group Company

transaction constituting a public offering or in a sale through the facilities
of any stock exchange.

                           (b) Upon original issuance and for such time as is
required under applicable requirements of the Securities Act or state securities
laws, the records of Den Norske Bank as registrar for the VPS system shall bear

the facilities and books and records of the Group Companies, for purposes of the
Seller's claim against Global Industries Ltd. relating to the Share Purchase

obligations under this Section 6.5 the Seller shall indemnify the Purchaser and
each Group Company against all reasonable out of pocket expenses incurred by it
in connection with the performance of such obligations (including the actual
cost of personnel of any Group Company that participates in the defense of the

First Closing, certain employees (who have been separately identified by the
Seller) will be transferred from the Company to the Seller or one of its
affiliates. The Seller hereby agrees to bear all costs relating to such
transfer, including any indemnity payments due to such employees and all
expenses relating to any claims made by such employees in connection with such
transfer.

                                    ARTICLE 7

                                 INDEMNIFICATION

                  7.1      PRINCIPLE

                           (a) Subject to the provisions of this Article 7, the
Seller hereby undertakes, from and after the First Closing Date, to indemnify
the Purchaser for, and to hold the Purchaser harmless against, all liabilities,
damages, losses and expenses and reasonable costs and expenses (including,
without limitation, fees of independent consultants, lawyers and accountants, as
well as fees associated with experts, fines, penalties and interest), in excess
of provisions for risk of the relevant nature in the June 30 Financial
Statements ("LOSSES") actually and directly suffered by the Purchaser or by any
of the Group Companies arising out of any inaccuracy or breach of the
representations and warranties or covenants of the Seller given under Articles
3, 5 and 6. For purposes of this Article 7, a provision shall be for a risk of
the "relevant

<PAGE>
                                                                             29.


nature" if (i) it was made in respect of a specific risk and relates to the type
of loss incurred (such as doubtful account, tax, pension or similar categories),
without regard to whether it was taken in respect of the specific item in
respect of which the loss was incurred, and in the case of tax and social
security matters, without regard to jurisdiction (except that provisions in
respect of taxes outside the European Union, Norway and Iran shall be considered
separately from provisions in respect of taxes inside the European Union, Norway
and Iran). For the avoidance of doubt, a provision may not be applied to reduce
the Seller's indemnification obligation if it has been applied prior to the date
of the Purchaser's indemnification claim to the specific risk in respect of
which it was originally made.

                           (b) In addition, the Seller hereby undertakes, from
and after the First Closing Date, to indemnify the Purchaser for, and to hold
the Purchaser harmless against, all Losses actually and directly suffered by the
Purchaser or by any of the Group Companies arising out of any liability of any
Group Company (i) to J.R. McDermott SA and/or any subsidiary or related company
thereof, under the Master Termination and Transfer Agreement, dated April 3,
1998, between J. Ray McDermott, S.A. and ETPM S.A. and all and any associated
agreement or instrument, or under the Sale and Purchase agreement dated April 3,
1998 between J.R. McDermott SA, the Company and others and associated agreements
and instruments and (ii) with respect to the matters set forth in EXHIBIT 7.1(B)
on the basis of any event occurring prior to the First Closing Date (any such
claim, a "MCDERMOTT CLAIM").

                           (c) In addition, the Seller hereby undertakes, from
and after the First Closing Date to indemnify the Purchaser for and to hold the
Purchaser harmless against (i) taxes (as defined in SECTION 3.10(F)), including
interest and penalties thereon, arising from any requirement that the Company or
any Group Companies make payment of any taxes or social security (or equivalent)
contributions in respect of a period ended prior to January 1, 1999, in excess
of provisions of the relevant nature included in the Financial Statements as of
December 31, 1998, and (ii) taxes (as defined in SECTION 3.10(F)) including
interest and penalties thereon, arising as a direct consequence of the
termination of the participation of the Company (and those of the Group
Companies that participate in the Seller's consolidated tax group) in the tax
consolidated group of the Seller. For the purpose of determining whether any
taxes were provided for in the balance sheet referred to in (c)(i), the last two
sentences of Section 7.1(a) shall apply MUTATIS MUTANDIS. Any such amount to be
indemnified by the Seller under Section 7.1(c)(i) is referred to as a "TAX
CLAIM".

                           (d) In addition the Seller hereby undertakes, from
and after the First Closing Date, to indemnify the Purchaser for and to hold the
Purchaser harmless against (i) any payment made by any Group Company arising
from a claim under any of the performance bonds listed in EXHIBIT 7.1(D)(I), and
(ii) all Losses suffered or to be suffered by the Company and/or other Group
Companies after June 30, 1999 in relation to the contracts relating to completed
projects set forth in EXHIBIT 7.1(D)(II).

                           (e) In addition, the Seller hereby undertakes, from
and after the First Closing Date, to indemnify the Purchaser for, and to hold
the Purchaser harmless against, all Losses suffered or to be suffered by the
Purchaser, any Purchaser Affiliate, the Company and/or

<PAGE>
                                                                             30.


other Group Companies in relation to the Global Claim, and for any claim by
Global Industries Ltd. arising out of or related to the Share Purchase
Agreement, dated August 2, 1999, between the Seller and Global Industries Ltd.
and any other documents related thereto.

                           (f) In addition, the Seller hereby undertakes, from
and after the First Closing Date, to indemnify the Purchaser for, and to hold
the Purchaser harmless against, all Losses suffered or to be suffered by any
Group Company arising from the sinking of the deck for the Chevron North Nemba
project that occurred on or about November 2, 1999.

                           (g) In addition, the Seller hereby undertakes, from
and after the First Closing Date, to indemnify the Purchaser for, and to hold
the Purchaser harmless against, any claim by an employee or former employee of
the Group Companies or other person (or persons representing the interests of
that employee or person) seeking compensation for harm suffered as a result of
an asbestos related illness to the extent such claim is based on exposure to
asbestos prior to the First Closing Date.

                           (h) In addition, the Seller hereby undertakes, from
and after the First Closing Date, to indemnify the Purchaser for, and to hold
the Purchaser harmless against, all Losses arising from taxes imposed on the
Group Companies as a result of the repurchase by the Company of 83,019 of its
shares on September 28, 1999.

                           (ha) In addition, the Seller hereby undertakes from
and after the First Closing Date, to indemnify the Purchaser for, and to hold
the Purchaser harmless against, 50% of all Losses in excess of the project
provision of US$ 2.3 million (up to a maximum indemnity payment of US$ 2
million) arising from the Subsea Offshore Limited claim referred to in point 4
of Exhibit 3.13(a). The parties acknowledge that the Company believes such claim
is the responsibility of the client or subcontractor, and that the undertaking
of the Seller hereunder with respect thereto does not change that position. The
Purchaser agrees to cause the Group Companies to permit the Seller to have its
representatives present during the defense and investigation of such claim and,
in accordance with Section 7.4, to control the defense thereof.

                           (i) In the event that any indemnity is due hereunder,
the Purchaser may direct the Seller to make payment to the affected Group
Company or Companies, it being understood that in no case will the Seller be
required to make any payment more than once in respect of any claim for which
indemnification is available hereunder.

                           (j) Any indemnification payment made by the Seller
shall be considered to be a post-First Closing reduction in the Purchase Price
for all purposes hereunder.

                  7.2      CLAIMS

                           7.2.1 Any claims made by the Purchaser under the
terms of this Article 7 (a "CLAIM") shall be made in writing as follows:

<PAGE>
                                                                             31.


                                    (a) each Claim shall state, with reasonable
                  detail, the specific grounds therefor and the amount claimed
                  or, if not then known, an estimate of the Losses; and

                                    (b) each Claim shall be made with reasonable
                  promptness after the Purchaser becomes aware of the
                  circumstances giving rise thereto; PROVIDED, HOWEVER, that any
                  failure to give such notice will not waive any rights of the
                  Purchaser except to the extent that the rights of the Seller
                  are actually prejudiced by the delay (in such latter case, the
                  rights of the Purchaser shall be diminished only by the direct
                  prejudice so incurred by the Seller).

                           7.2.2 Upon receipt of such notice, the Seller shall
respond with reasonable promptness, indicating any good faith objections to such
Claim and/or the amount thereof, it being understood that any failure to give
such notice will not waive any rights of the Seller to raise any further
objections, except to the extent that the grounds for any objection are then
known to the Seller and the rights of the Purchaser are actually prejudiced by
the delay.

                           7.2.3 Indemnification due by the Seller pursuant to a
Claim shall be paid by the Seller within five Paris business days of the later
of (i) the payment or actual incurrence by the relevant Group Company of the
Loss, or (ii) the earliest of:

                                    (a) the express acceptance of the Claim by
                  the Seller or,

                                    (b) the date on which an amicable agreement
                  is reached by the Parties with respect to a Claim or,

                                    (c) the date that a final, non-appealable
                  judicial decision is rendered in accordance with the
                  provisions of Section 9.11.

                           7.2.4 In the event that the Seller fails to make any
payment of the indemnification due to the Purchaser within the time-limits
provided for in Section 7.2.3, the unpaid Losses shall bear interest at the rate
of 3 month LIBOR plus 2.5% per annum, from the date of expiration of such
time-limit until the date so paid in full, without any official notice (MISE EN
DEMEURE) being necessary from the Purchaser.

                           7.2.5 When the Loss shall not be incurred in US
Dollars, the calculation of the Loss in US Dollars shall be made on the basis of
the applicable exchange rate published in the London Edition of the FINANCIAL
TIMES most recently prior to the date of payment by the Seller of the Claim.

                           7.2.6 The Seller agrees that it may not seek
reimbursement from any Group Company pursuant to the tax sharing agreement named
"Convention d'integration fiscale" dated December 23, 1998, between the Seller
and the Company, for any amount that is or becomes the subject of any Tax Claim
hereunder.

                  7.3      DEADLINES FOR CLAIMS

                           7.3.1 Subject to the provisions of Section 7.3.3, any
Claims may give rise to indemnification only if notified by the Purchaser to the
Seller (i) prior to the expiration of a twenty month period following the First
Closing Date, (ii) for Claims related to Section 3.16 or 7.1(g) within seven
years and six months following the First Closing Date, (iii) for Claims relating
to Section 3.14 (insofar as it relates to any violation of any anti-trust or
similar laws prohibiting anti-competitive behavior (an "ANTI-TRUST CLAIM")),
within five years following the First Closing Date or (iv) for (A) any Claim
related to taxes or social security charges, or any other amount contemplated in
Section 7.1(c) or 7.1(h), or (B) any Claim arising pursuant to Section 7.1(d),
7.1(f) or 7.1(g), at the latest sixty days after the expiration of the
applicable statutory limitation period with respect to a claim by any relevant
third party against the Purchaser, any Purchaser Group Company or any Group
Company that is the subject of such claim. There will be no limit with respect
to the date on which the Purchaser may notify any McDermott Claim or any Claim
arising pursuant to Section 7.1(e) or a claim with respect to a breach of
Section 3.17(g).

                           7.3.2 Upon expiration of these time-limits, the
Purchaser shall have no right to bring a Claim against the Seller under this
Agreement, provided, however, that the Seller shall remain liable for any
unresolved Claim notified by the Purchaser prior to such dates. In particular,
where a Claim, notified in accordance with Article 7.3.1, is based upon a
liability which is contingent only or the amount of which is not definitive at
the time of the notification, the obligation of the Seller to indemnify the
Purchaser shall survive until such liability becomes definitively determined and
due and payable.

                           7.3.3 Notwithstanding the above, no deadlines for
Claims shall apply to any Claim which, or delay in the discovery of which, is
the consequence of fraud, willful misconduct or willful concealment.

                  7.4      THIRD-PARTY CLAIMS

                           (a) In the event that a Claim is made on the basis of
a claim made by a third party against a Group Company, provided that the amount
of the claim, together with all other Losses then claimed by the Purchaser is
not in excess of the aggregate amount of the indemnification set forth in
Section 7.6(c), the Seller may retain counsel at its own expense to defend the
interests of the Group Company involved, subject to the notification of the
election by the Seller to retain such counsel to the Purchaser within thirty
days from the date of receipt of the Claim by the Seller.

                           (b) If the Seller has elected to so retain counsel in
accordance with the provisions of paragraph 7.4(a), then at the Seller's request
the Purchaser shall cause such Group Company to present all arguments, submit
all pleadings, take all actions, file all counterclaims, make available all
necessary personnel of such Group Company, and more generally cooperate with the
Seller and the counsel appointed by the Seller, in each case to the extent
reasonably requested by the Seller or its counsel. The Purchaser shall provide,
and shall cause the Group

                                                                             33.


Companies to provide, the Seller with all information or documents in relation
to any such third-party claim which the Seller may reasonably request. The
Purchaser shall not, and shall cause the Group Companies not to, settle, admit
liability or withdraw any claim in connection with any such third-party claim
without the prior written consent of the Seller.

                           (c) The Purchaser's obligations under this Section
7.4 are conditional upon its being indemnified to its reasonable satisfaction by
the Seller against all reasonable out of pocket expenses incurred by it or by
any Group Company in connection with the performance of such obligations
(including the actual cost of personnel of any Group Company that participates
in the defense of any third party claim at the request of the Seller, except in
connection with any Claim arising under Section 7.1(d)).

                           (d) Where the Seller takes over the conduct of
proceedings or negotiations pursuant to this Section 7.4, the Seller will not
settle any such proceedings or agree on any final outcome of such negotiations
without the prior written consent of the Purchaser (which shall not be
unreasonably withheld or delayed), unless in connection with such settlement the
Purchaser and the Group Companies are fully released from any liability.

                  7.5      EFFECTIVE NATURE OF THE LOSS

                           (a) Any indemnification due by the Seller shall be
calculated taking into account (i) the effect of any tax savings realized by the
Purchaser or Group Companies when the Loss occurred as a result of the tax
deductibility of the relevant Loss, and (ii) the tax impact (for the recipient
of the indemnification) of the indemnification to be paid by the Seller (except
that if the tax impact to the Group Company that actually suffered the relevant
Loss would have been lower had the indemnification payment been made to such
Group Company, then only such lower tax impact will be taken into account). For
purposes of clause (i), tax savings shall be considered "realized" if they
result in an actual cash savings to a Group Company, or if they are recorded as
tax benefits of deferred tax assets in the consolidated financial statements of
the Company (or any successor in interest to the Company) and its consolidated
subsidiaries.

                           (b) If a Claim is based upon a liability which is
contingent only, no indemnification shall be due unless and until such liability
becomes due and payable provided that for the purposes of clarity the fact that
a Claim is based on a liability which is contingent only shall not prevent the
Purchaser from delivering a Claim to the Seller pursuant to Sections 7.2.1 and
7.3.1.

                           (c) The Seller shall not be held liable for
indemnification of any Loss sustained by a Group Company, to the extent that
such Loss is compensated by a gain accruing to the benefit of another Group
Company with respect to the same facts and circumstances.

                  7.6      LIMITATION OF INDEMNIFICATION

                           (a) No indemnification shall be due by the Seller
under Section 7.1(a) of this Agreement unless the aggregate amount of the
indemnification owed by the Seller (but for

                                                                             34.


this subsection (b)) exceeds (after all deductions pursuant to this Article 7)
US$2,000,000, and such indemnification shall then become due for the portion
exceeding such amount.

                           (b) The Purchaser shall not be entitled to
indemnification for any individual Claim in an amount less than US$100,000,
unless such Claim relates to a Loss being one of a series or group of related
Losses which have the same origin and which taken together have a value in
excess of such amount. Any Claim that is less than this amount of US$100,000
shall not be counted in determining whether the threshold set forth in
subsection (a) has been met. Notwithstanding the foregoing, the provisions of
this Section 7.6(b) shall not apply to any McDermott Claim, or any Claim arising
under Sections 3.17(g), 7.1(c)(ii), 7.1(d), 7.1(e), 7.1(g) or 7.1(h).

                           (c) The aggregate amount of indemnification that the
Seller may be required to pay to the Purchaser in respect of all Claims
hereunder shall not exceed US$65 million, provided that:

                                    (i) the maximum amount that the Seller may
                  be required to pay to the Purchaser with respect to the
                  following Claims (taken together) shall be 100% of the sum of
                  the Purchase Price and US$ 70 million:

                                            (A)     Claims made under any of
                                                    Sections 3.1, 3.2, 3.3, 3.4,
                                                    3.5 (with respect to the
                                                    Company and the Shares
                                                    only), 3.6, 3.8 (with
                                                    respect to ownership and of
                                                    encumbrances over the
                                                    Vessels) or 3.17(g);

                                            (B)     Claims made pursuant to
                                                    Section 7.1(d)(i), 7.1(f),
                                                    7.1(g) or 7.1(h); or

                                            (C)     any Anti-Trust Claim;

                                    (ii) there shall be no limitation on the
                  amount that the Seller may be required to pay to the Purchaser
                  with respect to:

                                            (A)     any McDermott Claim;

                                            (B)     any Tax Claim with respect
                                                    to any payment or any amount
                                                    owing by the Company or any
                                                    Group Company in France, the
                                                    United Kingdom, Norway,
                                                    Holland, Denmark or Iran;
                                                    and

                                            (C)     Claims under section
                                                    7.1(d)(ii) (insofar as they
                                                    relate to the matters
                                                    identified in Exhibit
                                                    7.1(d)(ii) as "Kharg", "HUT"
                                                    and "Alcatel") or 7.1(e).

                  7.7      EXONERATING AND MITIGATING FACTORS

<PAGE>
                                                                             35.


                           (a) The Seller shall not be held liable for
indemnification to the extent the Loss for which indemnification is sought may
be attributed to any voluntary action or omission on the part of the Purchaser
and/or the Group Companies after the First Closing Date which is outside the
ordinary course of business of the Group Companies or any change in accounting
methods (including consolidation methods) or policies of the Group Companies
after such date.

                           (b) The Seller shall not be liable for
indemnification to the extent that (i) it relates to any Loss which is
reasonably recoverable under any policy of insurance effected by or for any
Group Company, or (ii) any Group Company modifies its insurance coverage so that
events prior to the First Closing that would otherwise have been covered by
insurance are not so covered. The fact that any Loss may be covered by insurance
shall not prevent the Purchaser or any Group Company from making a Claim to the
extent necessary to avoid the expiration of the limitation periods set forth
herein, in which case the Seller shall not be required to make payment for any
amount potentially covered by insurance until the extent of such insurance
coverage is finally determined.

                           (c) Upon learning of the situation giving rise or
likely to give rise to a Loss, the Purchaser shall use, and shall cause the
Group Companies to use, all reasonable efforts to mitigate the amount of such
Loss.

                           (d) In the event that a situation giving rise to a
Claim is curable, in whole or in part, the Purchaser shall give, or cause the
Group Companies to give, the Seller a reasonable opportunity to implement such a
cure.

                           (e) The right of the Purchaser to indemnification
hereunder shall not be affected by any investigation made by the Purchaser prior
to the date hereof or prior to the First Closing Date, or by any notice, oral or
in writing, of an exception to the representations and warranties contained
herein, unless such exception is fully disclosed in writing and adequately set
forth in the Exhibits attached hereto.

                           (f) Any deficiency assessed by the tax authorities
whose sole effect is to shift a tax liability from one fiscal year to another
shall give rise to indemnification by the Sellers limited to the amount of any
penalty or interest charge in relation thereto. Any deficiency assessed with
regard to a tax, such as a value-added tax, which is recoverable shall give rise
to indemnification by the Sellers only insofar as a Group Company is required to
pay a penalty or interest charge in relation thereto.

                  7.8      NO OTHER REPRESENTATIONS

                           (a) The Seller neither makes any representation nor
gives any warranty to the Purchaser other than as specifically provided in
Article 3 or otherwise in the Transaction Documents. Without limiting the
generality of the foregoing, the Seller makes no representation and gives no
warranty to the Purchaser with respect to financial projections, budgets or

                                                                             36.


management analyses relating to any of the Group Companies and to the future
profitability and financial performance of any of the Group Companies.

                           (b) Each of the parties acknowledges and agrees that
(i) none of the directors, officers or employees of any of the Group Companies
has made any representation or warranty to the Purchaser, either express or
implied, regarding the Group Companies, the conduct of their businesses or the
accuracy or completeness of any of the information provided or made available to
the Purchaser or its agents and (ii) none of such persons shall have any
liability or responsibility to it in respect thereof.

                  7.9      PURCHASER INDEMNITY

                  Subject to the provisions of this Article 7, the Purchaser
hereby undertakes, from and after the First Closing Date, to indemnify the
Seller for, and to hold the Seller harmless against, all Losses actually and
directly suffered by the Seller arising out of any inaccuracy or breach of the
representations and warranties or covenants of the Purchaser given under
Articles 4 and 6. The provisions of Sections 7.2 through 7.8 shall apply MUTATIS
MUTANDIS to any claim by the Seller in respect of such indemnity (with
references to the Purchaser being instead to the Seller, and vice versa), except
that:

                           (i) The liability of the Purchaser to the Seller for
all breaches by the Purchaser shall be limited to the Purchase Price, except
with respect to any breach of the representations set forth in Sections 4.4,
4.5, 4.6 and 4.7, in respect of which the liability of the Purchaser to the
Seller shall be limited to $107.5 million; PROVIDED, HOWEVER, that in each case
the liability hereunder shall be reduced by any amount that the Seller shall
have previously received from the Purchaser or a third party upon any resale of
the Purchaser Shares in accordance with Annex III; and PROVIDED, further that
the Purchaser's aggregate liability for indemnification hereunder shall not
exceed the Purchase Price except as set forth below; and

                           (ii) Nothing in this Section 7.9 shall be construed
to affect the Seller's right to indemnity or contribution in the circumstances
contemplated in Annex I.

                  7.10     WAIVER OF RESCISSION, EXCLUSIVITY OF REMEDY

                  From and after the First Closing Date, the indemnification
provided in this Article 7 shall be the exclusive remedy of each of the parties
hereto against the other in respect of any breach of any representation,
warranty, covenant or undertaking by that other party and each of the parties
hereto waives any right to rescission it may have with respect to this
Agreement.

                  9.1      COOPERATION

                  Each of the parties hereby undertakes to make every effort to
take all measures or to ensure that all measures necessary or useful are taken
in a timely manner for the completion of the transactions provided for in this
Agreement. In the event that after the First or Second Closing Date, any
additional measures are necessary or desirable for the completion of the
transactions contemplated herein, the parties shall take all such measures, or
shall ensure that they are taken.

                  9.2      CONFIDENTIALITY AND ANNOUNCEMENTS

                           (a) Each party hereto agrees to maintain in
confidence, and not use in any manner other than in connection with the
consummation of the transactions contemplated hereby, any written, oral or other
information obtained from the other party hereto or the Group Companies in
connection with this Agreement or its review of the business and affairs of the
Group Companies hereunder, unless (i) such information is already known to such
party or becomes known to it from others not bound by a duty of confidentiality
or such information becomes publicly available through no fault of such party,
(ii) the other party gives its prior written consent, or (iii) the disclosure of
such information is required by applicable law or regulation (in which case the
party proposing to make such disclosure shall consult with the other party prior
to such disclosure). If the transactions contemplated hereby are not
consummated, then each of the parties will return to the other party all written
information so obtained and, in any event, continue to maintain all information
so obtained in confidence.

                           (b) Neither party shall make any public announcement
relating to this Agreement or the transactions contemplated herein without the
consent of the other party, except to the extent that such announcement is
required by applicable law or regulation, in which case the other party shall
have the opportunity to review and comment on such announcement before it is
made.

                  9.3      ABSENCE OF THIRD-PARTY RIGHTS - ASSIGNMENT

                  This Agreement is for the sole benefit of the parties hereto,
and shall not benefit or create any rights whatsoever in favor of any individual
or entity other than the parties hereto. This Agreement shall not be assigned by
either party without the prior written consent of the other party hereto, except
that if the Purchaser designates a wholly-owned subsidiary to acquire the Shares
pursuant to Section 2.2(a)(i), the Purchaser may assign its rights (but not its
obligations) under this Agreement (including without limitation pursuant to
Article 7) to such subsidiary, which assignment may remain effective so long as
such subsidiary remains wholly-owned by the Purchaser.

                                                                             38.


                  The Transaction Documents (including the Exhibits and Annexes
thereto) represent the entire agreement existing between the parties relating to
the subject matter hereof and supersede all prior understandings and agreements
of the parties with respect to the subject matter hereof. The Purchaser

the Group Companies and their businesses. In entering into this Agreement, the
Purchaser has relied solely upon its own investigation and analysis and on the
representations and warranties expressly set forth in the Transaction Documents.

                  9.5      WAIVERS AND AMENDMENTS

                  No modification of or amendment to this Agreement shall be
valid unless set forth in an instrument in writing signed by each of the parties
hereto. Any waiver of any term or condition of this Agreement must be set forth
in an instrument in writing signed by the waiving party and must refer
specifically to the term or condition to be waived and to the circumstances of
such waiver. No such waiver shall be deemed to constitute a waiver applicable
either to other circumstances involving the same term or condition or to any
other term or condition of this Agreement.

                  9.6      SEVERABILITY

                  If any provision of this Agreement is held to be invalid in
whole or in part, the validity of the remaining provisions of the Agreement
shall not be affected. In such event, the parties shall, if possible, substitute
for such invalid provision a valid provision corresponding to the spirit and
purpose thereof.

                  9.7      SECTION HEADINGS

                  The section headings in this Agreement are for convenience of
