Auditors confirming such objections and computations of the Disputed Items. Upon
delivery of the Disputed Items Notice, the Purchasers and CGG shall use all
reasonable endeavors to meet and discuss the objections of the Purchasers and to
resolve the Disputed Items, draw up an agreed adjustments to the Audited Closing
Balance Sheet and finally determine the Adjustment Amount (if any), as promptly
as practicable.

     The Purchasers shall procure that the Appointed Auditors are provided with
all reasonable access to the premises of the Companies and to the accounting and
other relevant books and records of the Companies as needed in connection with
their review of the Disputed Items.

     2.5.5 Dispute Resolution

     (i) If the Purchasers and CGG do not agree upon the Adjustment Amount (if
any) within twenty (20) days after delivery of the Disputed Items Notice (or
such longer period as the Purchasers and CGG may agree in writing), the
Purchasers and CGG shall each have the right to request that KPMG,
PriceWaterHouseCoopers or Deloitte, Touch Tomatsu (the "Independent Expert"),
resolve the Disputed Items and make a final determination of the Adjustment
Amount (if any), based on its resolution of such Disputed Items; provided,
however, that, when so requested, the Independent Expert and any related Entity
shall not so act if they are in a position of conflict of interest with any of
the parties hereto and the partner in charge of the matter at the selected
Independent Expert shall be a qualified US CPA.

     (ii) The Independent Expert shall be selected jointly by the Appointed
Auditors (acting as CGG's agent) and the Purchasers' Auditors (acting as the
Purchasers' agent) from among Eligible Accounting Firms.

     (iii) If the Appointed Auditors and the Purchasers' Auditors have not
agreed upon the selection of the Independent Expert within thirty (30) days
after notice to the parties from, or a determination by, the selected
Independent Expert that it is unwilling or unable to act as the Independent
Expert, the Independent Expert shall be appointed by the President of the Courts
of Paris (Tribunal de Grande Instance de Paris) acting in summary proceedings
(statuant comme en matiere de refere) at the request of the first party to make
such request, with each party having the opportunity to be heard, from among
Eligible Accounting Firms


                                      -11-

<PAGE>


(other than the Appointed Auditors and the Purchasers' Auditors or any other
accounting firm which may be in a conflict of interest position with any of the
parties hereto).

     2.5.6 Final Determination. The Independent Expert shall apply the
directives and principles set forth in this Agreement to resolve the Disputed
Items as to which CGG and the Purchasers have not agreed and to complete the
final determination of the Adjustment Amount (if any). The Independent Expert
shall not review any item other than those required to resolve the Disputed
Items which CGG has not accepted in writing nor proceed with any further
investigations, but shall base its decision exclusively on the materials and
arguments presented by the parties and their respective Auditors (which
materials shall not include any materials not referred to previously in the
preparation of the notices contemplated by this Section 2.5). The parties shall,
and the Purchasers shall procure that the Companies shall, cooperate with the
Independent Expert in all reasonable respects.

The parties shall instruct the Independent Expert to simultaneously deliver to
CGG and to the Purchasers a letter (the "Independent Expert's Letter") setting
forth its final determination of the Adjustment Amount (which shall in no event
be more favorable to the Purchasers than that set forth in the Disputed Items
Notice or more favorable to CGG than that set forth in the Adjustment
Certificate) within the shortest practicable time and shall use its reasonable
efforts to do so within thirty (30) days after its appointment and delivery of
all relevant information. Such final determination shall, except in the case of
manifest error, be final and binding on the parties hereto, and shall be given
by the Independent Expert as an expert and not as an arbitrator.

The fees, costs and expenses of the Independent Expert so selected will be
borne, in the manner determined by the Independent Expert and if no
determination is made, equally between CGG, on the one hand, and the Purchasers,
on the other hand.

For the purposes hereof, either (i) the definitive Audited Closing Balance Sheet
agreed upon by CGG and the Purchasers pursuant to Section 2.5.4 above, or (ii)
in the absence of an agreement between CGG and the Purchasers, the Audited
Closing Balance Sheet read in light of the Independent Expert's Letter delivered
by the Independent Expert pursuant to this Section 2.5.6, is referred to herein
as the "Final Closing Balance Sheet".

     2.5.7 Conclusive Presumptions

     (A) If the Purchasers shall not have delivered the Disputed Items Notice
(together with the related report of the Purchasers' Auditors) to CGG within
forty-five (45) days after the Delivery Date, the Adjustment Amount, if any, set
forth in the Adjustment Certificate shall be conclusively presumed to be true
and correct in all respects and shall be binding on the parties and may not be
disputed by them in any forum.

     (B) If the Purchasers shall have delivered a Disputed Items Notice
(together with the related report of the Purchasers' Auditors) to CGG within

Items Notice that CGG do not agree with the Purchasers' determination of the
Adjustment Amount set forth in the Disputed Items Notice, the Adjustment Amount
set forth in the Disputed Items Notice shall be conclusively presumed to be true
and correct in all respects and shall be binding on the parties and may not be
disputed by them in any forum.

final determination of the Adjustment Amount pursuant to Sections 2.5.1. through
2.5.7 above, if the Purchasers shall deliver a written notice to CGG at any time
after the delivery of the Adjustment Certificate to the effect that they agree
with the computation of the Adjustment Amount set forth in the Adjustment
Certificate, then the final determination of the Adjustment Amounts shall be
deemed to have occurred on the date of the receipt by CGG of such written notice
of agreement.

     2.5.9 Final Payments. The parties shall (x) settle any amounts due in
respect of the Adjustment Amount, and (y) pay or cause to be paid (by the
Companies, in the case of the Purchaser, and by its relevant Affiliates, in the
case of CGG) any Intercompany Payables reflected in the Final Closing Balance
Sheet (to the extent then outstanding), within five (5) Business Days after the
final determination of the Adjustment Amount in accordance with the procedures

the accounting and other relevant books and records of CGG and its Affiliates as
may be reasonably required for the preparation of any such financial statements
and will provide explanations and assistance to such auditors to the extent
reasonably requested. CGG acknowledges that such financial statements may be
filed by Paradigm with various regulatory authorities to which it is subject and
become public, and may vary from financial statements and information previously
prepared by the Companies.

similar levies that may become payable as a result of the signing of this
Agreement, the transfer of the Securities or the issuance of the Paradigm Shares

of CGG, is any work, repair or capital expenditure required in respect of the
properties and assets (including real property) of the Companies pursuant to or
to comply with any Environmental Law, where the failure to undertake such work,
repair or capital expenditure could reasonably be expected to result in an
Environmental Claim having a Material Adverse Effect.

     3.1.22 Disclosure. To the knowledge of CGG, there is no fact or facts
peculiar to the Companies which CGG has not disclosed to Paradigm in writing
which could reasonably be expected to have, individually or in the aggregate, a
Material Adverse Effect.

     3.1.23 Securities Act Matters. CGG is acquiring the Paradigm Shares for its
own account, for investment purposes only, and not with a view to the resale or
distribution of any part thereof in violation of any applicable securities law.
CGG understands that the Paradigm Shares have not been registered under the U.S.
Securities Act of 1933, as amended (the "Securities Act"), or under the
securities laws of the various states of the United States, by reason of an
exemption from the registration provisions thereunder. CGG acknowledges that its
representations and warranties contained in this Section are being relied upon
by Paradigm as a basis for the exemption of the issuance of the Paradigm Shares
hereunder from the registration requirements of the Securities Act and any
applicable state securities laws. CGG understands that all certificates for the
Paradigm Shares issued to CGG shall bear a legend in substantially the following
form:

          "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
          1933, AS AMENDED. THE SECURITIES MAY NOT BE OFFERED, SOLD, TRANSFERRED
          OR OTHERWISE DISPOSED OF WITHOUT SUCH REGISTRATION OR THE DELIVERY TO
          THE ISSUER OF AN OPINION OF COUNSEL, REASONABLY ACCEPTABLE TO THE
          ISSUER, OR OTHER EVIDENCE REASONABLY ACCEPTABLE TO THE ISSUER, THAT
          SUCH DISPOSITION WILL NOT REQUIRE REGISTRATION OF SUCH SECURITIES
          UNDER THE SECURITIES ACT OF 1933, AS AMENDED."

                         REPRESENTATIONS AND WARRANTIES
                                OF THE PURCHASERS

4.1 Representations and Warranties of the Purchasers
    ------------------------------------------------

authorization and execution of this Agreement and the Registration Rights
Agreement by

<PAGE>


CGG, constitute the legal, valid and binding obligations of Paradigm,

     (B) Paradigm USA is a corporation duly incorporated and organized and is

authorized by all necessary action by the board of directors of Paradigm USA and
no other corporate proceeding on the part of Paradigm USA are necessary to
authorize Paradigm USA's entering into this Agreement or the performance of its
obligations hereunder. This Agreement has been duly executed by Paradigm USA
and, assuming the due authorization and execution of this Agreement by CGG,
constitutes a legal, valid and binding obligation of Paradigm USA, enforceable
against it in accordance with its terms.

     4.1.2 No Conflict or Violation. Neither the execution and delivery of this
Agreement and the Registration Rights Agreement by the relevant Purchasers, nor
the consummation of the transactions contemplated hereby or thereby nor the
fulfillment by the relevant Purchasers of the terms, conditions and provisions
hereof and thereof will (with or without the giving of notice or lapse of time,
or both):

     (A) contravene or violate the Organizational Documents or any resolutions
of any of the Purchasers or any amendments thereto or restatements thereof;

     (B) contravene or violate any Laws or Judgments applicable to any of the
Purchasers or require any Governmental Authorizations (other than filings to be
made after the Closing under the provisions of the Exchange Act, as amended and
with the Israeli Registrar of Companies);

     (C) contravene, violate or result in the breach of, or give any other party
the right to declare a default under, accelerate the performance of, or cancel,
modify or terminate its obligations under, any material Contract to which any of
the Purchasers is a party or by which it is bound; or

     (D) result in the creation or imposition of any Encumbrance on any of the
assets of any of the Purchasers.

     4.1.3 Issuance of Paradigm Shares. The Paradigm Shares to be sold and
issued to CGG in accordance with the terms of this Agreement have been duly
authorized and, when issued as contemplated hereby, will be validly issued in
compliance with all applicable Laws, fully paid and non-assessable, and no other
Person has any preemptive right, option, warrant, subscription agreement or
other right with respect to such Shares. Upon the issuance of the Paradigm
Shares, CGG will acquire good and marketable title to the Paradigm Shares free
and clear of any and all Encumbrances, except such Encumbrances as may be
created pursuant to this Agreement or by CGG.

     4.1.4 Commission Reports. Paradigm has filed with the United States
Securities and Exchange Commission (the "Commission") all forms, reports,
filings, proxy materials, registration statements and other documents required
to be filed by it under the U.S. federal securities laws (the "Commission
Filings"). The Commission Filings (as of their respective


                                      -24-

<PAGE>


filing dates, mailing dates or effective dates, as the case may be) complied in
all material respects with the applicable requirements of the U.S. federal
securities laws and did not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading. Each of the consolidated balance sheets
(including the related notes) included in the Commission Filings fairly presents
in all material respects the financial position of Paradigm and its consolidated
Subsidiaries as of the respective date thereof, and each of the other related
statements (including the related notes) included therein fairly presents in all
material respects the results of operations and cash flows of Paradigm and its
consolidated Subsidiaries for the respective period or as of the respective date
set forth therein. Each of the consolidated balance sheets and statements of
operations and cash flows (including the related notes) included in the
Commission Filings has been prepared in accordance with generally accepted
accounting principles applied on a consistent basis during the period involved,
except as otherwise noted therein, and subject, in the case of unaudited interim
financial statements, to normal year-end adjustments. Paradigm has fully
complied in all material respects with the Israeli Securities Law of 1968 and
with the applicable term of any exemption granted thereunder. Paradigm
acknowledges that CGG is relying on the Commission Filings with respect to its
purchase of the Paradigm Shares pursuant to this Agreement. Since June 30, 2000,
there has been no material adverse change in the business, financial condition
or results of Paradigm and its Subsidiaries, taken as a whole, other than
changes prevailing in the business sector in which Paradigm operates, and
Paradigm and its Subsidiaries have not entered into any material transactions
(other than in the Ordinary Course of Business) other than as reflected in the
Commission Filings.

     4.1.5 Listing of Ordinary Shares. The outstanding Ordinary Shares of
Paradigm are listed on the Nasdaq National Market, and Paradigm's listing
agreement with respect thereto is in full force and effect. No action has been
taken or threatened by Nasdaq with respect to the delisting or suspension from
trading of the Ordinary Shares. The Paradigm Shares to be issued to CGG have
been approved for listing on the Nasdaq National Market (subject to notice of
issuance).

     4.1.6 Foreign Private Issuer. Paradigm is a "foreign private issuer," as
defined in Rule 3b-4 of the Exchange Act.

     4.1.7 Share Capital. The authorized share capital of Paradigm consists in
its entirety of 18,000,000 Ordinary Shares, of which, as of August 30, 2000,
13,191,902 are issued and outstanding and 2,000,000 Special Preferred Shares,
none of which are issued and outstanding. In addition, as of August 30, 2000 (a)
an aggregate of 2,239,814 Ordinary Shares are reserved for issuance pursuant to
Paradigm's 1994 Stock Option Plan for key employees, the May 1994 Stock Option
Plan, the 1994 General Stock Option Plan, the 1997 Stock Option Plan for
Qualifying Israel Employees, the 1997 Executive Stock Option Plan and the 1997
Stock Option Plan for U.S. Employees (collectively, the "1994 and 1997 Stock
Option Plans"), of which options to purchase 1,891,406 Ordinary Shares were
outstanding as of August 30, 2000; and (b) 612,861 Ordinary Shares are reserved
for issuance in connection with the exercise of certain outstanding warrants.
All of the above outstanding shares have been duly authorized and validly
issued, are fully paid and non-assessable, are not subject to preemptive rights,
and are owned by Paradigm's shareholders free and clear of any Encumbrances
imposed or created by Paradigm. Except as set forth in Schedule 4.1.7, none


                                      -25-

<PAGE>


of the outstanding capital shares of Paradigm are subject to any co-sale right,
registration right, right of first refusal or other similar right to purchase
any shares pursuant to any agreement to which Paradigm is a party or otherwise
imposed or created by Paradigm or imposed by Israeli law. Other than as
described above, there are no outstanding options, warrants or other rights
calling for the issuance of, and no commitments, plans or arrangements to issue,
any capital shares of Paradigm or any security convertible into or exchangeable
for share capital of Paradigm. All shares to be issued upon the exercise of
outstanding warrants or options or upon the conversion of any security shall be,
when issued or sold in accordance with the terms of the applicable agreements,
validly issued, fully paid and non-assessable. An "Initial Public Offering", as
such term is used in Paradigm's Articles of Association, has occurred.

     4.1.8 Litigation. Except as disclosed in Commission Filings, there is no
claim or Proceeding pending or, to the knowledge of Paradigm, threatened in
writing against or affecting Paradigm or any of its Subsidiaries or the assets
of any of them which could have, individually or in the aggregate, a Material
Adverse Effect on Paradigm and its Subsidiaries (taken as a whole), or a
material adverse effect on Paradigm's ability to perform or observe any
obligation or condition under this Agreement. To the knowledge of Paradigm,
there is no basis for a claim against Paradigm or any of its Subsidiaries which
is reasonably likely to be asserted and which could reasonably be expected to
have a Material Adverse Effect on Paradigm and its Subsidiaries (taken as a
whole).

     4.1.9 Industrial Company. Paradigm is qualified as an "Industrial Company"
within the definition of the Law for the Encouragement of Industry (Taxes),
1969. To the knowledge of Paradigm, there is no reason for disqualifying
Paradigm from being an Industrial Company, nor would such reason arise through
the conduct and performance of Paradigm's business and operations in accordance
with its plans and projections (including as a result of the transactions
contemplated hereby).

     4.1.10 Compliance with Laws. Each of Paradigm and its Subsidiaries is in
compliance with all Laws and Judgments applicable to it, except where the
failure to so comply could reasonably be expected to have, individually or in
the aggregate, a Material Adverse Effect, including without limitation, the
provisions of the Law for Encouragement of Capital Investments, 1959, applicable
to Paradigm and the terms of any "Approval Letter" issued to Paradigm thereunder
and its extensions, amendments and supplements, if any.

     4.1.11 Disclosure. To the knowledge of Paradigm, there is no fact or facts
peculiar to Paradigm or any of its Subsidiaries which Paradigm has not disclosed
to CGG in writing or in the Commission Filings which could reasonably be
expected to have, individually or in the aggregate, a Material Adverse Effect.

4.2 Purchasers' Acknowledgment
    --------------------------

     The Purchasers acknowledge that they and their advisors have been given
access to a data room organized by CGG and have reviewed to their reasonable
satisfaction the documents and information listed on Schedule 4.2 (the "Data
Room Documentation" (copies of which are attached to such Schedule except to the
extent appearing at other Schedules)), and in entering into this Agreement, have
taken into account their own review and analysis of the Data Room Documentation
(it being understood that in relation to any matter covered by a representation


                                      -26-

<PAGE>


or warranty of CGG expressly set forth in this Agreement, the Purchasers shall
be entitled to rely solely upon such representation or warranty).

                                   ARTICLE V
                                COVENANTS OF CGG

5.1 Geovecteur Accounts Receivable
    ------------------------------

     CGG shall, and shall procure that its Affiliates shall, promptly upon their
receipt from third parties of payment of amounts due to them under accounts
receivable outstanding on September 30, 2000 and related to the Geovecteur
Business, pay the amount thereof to Flagship on account of the corresponding
Geovecteur Account Receivable. On December 29, 2000 (or if such date is not a
Business Day, on the immediately preceding Business Day), CGG will pay to the
Companies, without any set-off or reduction, the unpaid balance of the
Geovecteur Accounts Receivable (net of reserves for doubtful accounts included
in the Final Closing Balance Sheet), whereupon the Purchasers shall cause the
Companies to assign all such unpaid Geovecteur Accounts Receivable to CGG.

5.2 CGG Flagship Accounts Receivable
    --------------------------------

     CGG shall, and shall procure that its Affiliates shall, promptly upon their
receipt from third parties of payment of amounts due to them under accounts
receivable outstanding on September 30, 2000 and related to the Flagship
Business, pay the amount thereof to Flagship on account of the corresponding CGG
Flagship Account Receivable. On March 31, 2001 (or if such date is not a
Business Day, on the immediately preceding Business Day), CGG will pay to the
Companies, without any set-off or reduction, the unpaid balance of the CGG
Flagship Accounts Receivable (net of reserves for doubtful accounts included in
the Final Closing Balance Sheet).

5.3 Covenant Not to Compete
    -----------------------

     Except as contemplated by the Umbrella Services Agreement or the Support
Agreement:

     (i) for a period of thirty-six (36) months following the date hereof, CGG
shall not, and shall procure that all of its Affiliates which it controls do
not, directly or indirectly, engage in the commercial sale (i.e., through the
granting of licensee) anywhere in the world of any products the same or similar
to those currently included in the Flagship Business; and

     (ii) CGG shall not, and shall procure that all of its Affiliates which it
controls do not, use commercially the names "Flagship", "Petrosystems",
"Stratimagic", "Seisfacies", "GEM", "Integral Plus", "Nexmodel" and "StratQC" or
otherwise simulate any of the foregoing names.

CGG and the Purchasers acknowledge the fact that a part of Stratimagic (the
"propagator") is included in some of the tools used by CGG or its Affiliates
centers in the course of their service activity to the clients. Should any of
the tools making use of the "propagator" be sold to a client (commercial sale
through the granting of license) by CGG or any of its Affiliates, a


                                      -27-

<PAGE>


royalty of U.S.$ 12,000 shall be paid to the Purchasers by CGG. It is specified
that the use of the "propagator" by CGG or its Affiliates is made on an "as is"
basis and that neither CGG nor any of its Affiliates will be entitled to claim
support or the supply of updates to such products. CGG further undertakes to pay
all third party royalties payments if and when due upon written notification by
the Purchasers or the Companies.

Furthermore, CGG and the Purchasers (for themselves and on behalf of the
Companies) recognize that a "software development toolbox" (i.e., a set of
software components; libraries, re-usables and modules which are not
applications) related to and derived from GEM exists within the CGG or its
Affiliates software development teams and that this software development toolbox
has independently evolved during the past two years and is now significantly
different. The parties nevertheless acknowledge that some similarities still
exist at the level of the non-geoscience common tools (particularly drag and
drop and base map).

The parties expressly agree that CGG and its Affiliates will retain the entire
and non restricted ownership of this software development toolbox and will
therefore be entitled to further use, develop and maintain such tool box. CGG
agrees not to, and shall procure that its Affiliates do not use the name "GEM"
any longer in any external communication. In consequence therefore, the parties
agree that any amount that may be due to the FSH will be shared equally between
CGG and Flagship SA and therefore CGG will reimburse as promptly as practicable,
upon presentation of appropriate documentation, half of any amount paid by
Flagship S.A. to the FSH with respect to the GEM project.

5.4 Lock-up
    -------

During the twelve-month period commencing on the date hereof, CGG and its
Affiliates shall not sell or otherwise dispose of, or enter into any agreement
to sell or dispose of, any of the Paradigm Shares without the authorization of
the Paradigm Board, except for (i) such sales or other dispositions as may be
permitted by the terms of the Registration Rights Agreement, and (ii) transfers
of Paradigm Shares to Affiliates.

5.5 Recommended Third Party Offer
    -----------------------------

     In the event that an third party which is not an Affiliate of Paradigm (a
"Third Party") makes an offer to purchase all or substantially all of the
outstanding shares of Paradigm (the "Third Party Offer"), which Third Party
Offer has been approved and recommended by the board of directors of Paradigm
(the "Paradigm Board"), and shareholders holding at least 75% of the outstanding
Ordinary Shares of Paradigm have accepted the Third Party Offer, CGG irrevocably
agrees, on behalf of itself and all of its Affiliates which it controls, to sell
their Ordinary Shares to the Third Party on the terms of the Third Party Offer,
provided that:

     (i) pursuant to the terms of the Third Party Offer, CGG and its selling
Affiliates will receive cash or securities traded on a major internationally
recognized stock exchange or regulated electronic trading market which are of a
number and character such that they may be disposed of by CGG and its selling
Affiliates on such stock exchange or regulated electronic trading market without
any legal or contractual limitations within twelve (12) months of the date of
receipt; and


                                      -28-

<PAGE>


     (ii) the sale of any such Ordinary Shares and/or the acceptance or receipt
of any such securities would not violate any Laws or any material Contracts to
which CGG or any of its selling Affiliates is subject.

5.6 Retention of Records
    --------------------

     CGG agrees that for a period of not less than four (4) years following the
date hereof, it shall not destroy or otherwise dispose of any of the books and
records of the Companies existing as of the date hereof except with the prior
written consent of Purchasers, which consent shall not be unreasonably withheld.
CGG agrees that it shall make available to Purchasers and their representatives
and agents all such books and records, and permit Purchasers and their
representatives and agents to examine, make extracts from and, at their expense,
copy such books and records at any time during normal business hours for any
proper business purpose.

                                   ARTICLE VI
                              COVENANTS OF PARADIGM

6.1 Guaranteed Obligations
    ----------------------

     The Purchasers shall cause the Companies fully to perform and observe all
the obligations required to be performed and observed by the Companies under
each agreement or other obligation of either of them identified on Schedule 6.1
and with respect to which CGG or any of its Affiliates is obligated as a
guarantor or assignor or identified as a party thereto, and shall promptly
reimburse CGG and its Affiliates for any payments made or other liabilities
incurred by any of them in respect of any such obligations; provided, however,
that the Purchasers shall use their best efforts to obtain the complete release
and discharge of the CGG and such Affiliates from such obligations by duly
executed instruments in form reasonably satisfactory to the CGG within sixty
(60) days of the date hereof and, if after using such best efforts, the
Purchasers are unable to obtain such release and discharge with respect to any
of such obligations, the Purchasers shall thereafter cause the Companies to take
all action necessary to terminate such obligation as soon as possible, including
but not limited to exercising any option to prepay or purchase contained
therein. Pending such complete release and discharge or termination, the
Purchasers shall not permit the Companies or any of their successors to default
under or amend or modify the terms of any such obligation for which CGG or any
of its Affiliates could still be liable, directly or indirectly, or exercise any
right to, or agree to, extend the terms of such obligation or assign or
subcontract any agreement or arrangement containing any such obligation to any
party.

6.2 Retention of Records
    --------------------

     The Purchasers agree that for a period of not less than four (4) years
following the date hereof, they shall not, and shall not permit any of the
Companies to, destroy or otherwise dispose of any of the books and records of
the Companies existing as of the date hereof except with the prior written
consent of CGG, which consent shall not be unreasonably withheld. The Purchasers
agree that they shall, and they shall cause the Companies to, make available to
CGG and its representatives and agents all such books and records, and permit
CGG and its representatives and agents to examine, make extracts from and, at
their expense, copy such books and records at any time during normal business
hours for any proper business purpose.

6.3 Paradigm Board Representation
    -----------------------------

     6.3.1 As long as CGG and its Affiliates hold in the aggregate more than 5%
of the outstanding Ordinary Shares of Paradigm, Paradigm will recommend to the
shareholders of Paradigm prior to any general meeting of shareholders of
Paradigm, at which directors may be proposed to be elected, to elect a
representative of CGG (the "CGG Representative") to the board of directors of
Paradigm (the "Paradigm Board"), and will take all lawful actions to solicit
such election provided that:

     (i) the CGG Representative is not directly involved in any business in
competition with any material businesses of Paradigm viz.: Geoscience software
and data processing and interpretation; and

     (ii) prior to the third anniversary date of this Agreement, without the
approval of the Paradigm Board, CGG and its Affiliates have not acquired
additional Ordinary Shares causing them to then hold in the aggregate a
percentage of the outstanding Ordinary Shares in excess of the percentage held
by CGG immediately after issuance of the Paradigm Shares.

     6.3.2 Paradigm will give CGG written notice reasonably in advance of the
preparation of proxy materials for each shareholders meeting at which directors

     (iv) to in all cases ensure that any CGG Representative elected to the

officers or directors, it shall be required to enter into indemnification
arrangements with the CGG Representative equivalent to the most favorable
treatment accorded any of its officers or directors). Paradigm shall indemnify
each of CGG and any CGG Representatives for and against any Damages suffered or
incurred by

6.4 Special Preferred Shares

<PAGE>


actions, cause of action, damages, losses, cost, liability or expense (including

7.5 Procedure for Indemnification
    -----------------------------

     The party making a claim for indemnification under this Article VII shall,
for the purposes of this Agreement, be referred to as the "Indemnified Party"
and the party or parties against whom such claims are asserted under this
Article VII shall, for the purposes of this Agreement, be referred to as the
"Indemnifying Party". All claims by any Indemnified Party under this Article VII
shall be asserted and resolved as follows:

     7.5.1 Claim Notices

     In the event that (A) any claim, demand or Proceeding is asserted or
instituted by any Person other than the parties hereto and their respective
Affiliates (a "Third Party") which, if successful, could give rise to Damages
for which an Indemnifying Party would be liable to an Indemnified Party
hereunder (any such claim, demand or Proceeding, a "Third Party Claim"), or


                                      -32-

<PAGE>


(B) any Indemnified Party hereunder shall have a claim to be indemnified by any
Indemnifying Party hereunder which does not involve a Third Party Claim (any
such claim, a "Direct Claim"), the Indemnified Party shall send to the
Indemnifying Party a written notice (a "Claim Notice") specifying in reasonable
detail the factual basis of such claim or demand and the amount or a good faith
estimated amount of related Damages (which estimate shall not be conclusive of
the final amount of such claim and demand) and such available supporting
evidence as may reasonably be required by the Indemnifying Party to assess the
merits of the claim and the computation or estimate of Damages.

     7.5.2 Time for Claim Notice

     The Indemnified Party shall send a Claim Notice (x) in the case of a Third
Party Claim, within thirty (30) days of receipt of actual notice of such Third
Party Claim (or such shorter period as may be warranted under the
circumstances); and (y) in the case of a Direct Claim, with reasonable
promptness in view of the circumstances (but in no event later than sixty (60)
days after the Indemnified Party (including the Companies in the case of the
Purchasers) first becomes aware of the facts upon which the Direct Claim is
based).

     7.5.3 Direct Claims

     In the event of a Direct Claim, the Indemnifying Party shall have thirty
(30) days following its receipt of the relevant Claim Notice (or if the amount
of the Claim was not determined at the time of the Claim Notice, the date on
which amount of the Claim has been notified by the Indemnified Party) (the
"Direct Claim Review Period") to make such investigation of the Claim as
reasonably necessary to determine the validity of the Claim. For the purpose of
such investigation, the Indemnified Party shall make available to the
Indemnifying Party the information relied upon by the Indemnified Party to
substantiate the Claim. If the Indemnified Party and the Indemnifying Party
agree at or prior to the expiration of the Direct Claim Review Period (or any
mutually agreed upon extension thereof) to the validity and amount of the claim,
the Indemnifying Party shall immediately pay to the Indemnified Party the full
agreed upon amount of the Claim, in the event that only part of the amount of
the Claim is in dispute, the Indemnifying Party shall immediately pay the full
amount which is not in dispute. If the Indemnified Party and the Indemnifying
Party do not reach agreement on or prior to the date of the expiration of the
Direct Claim Review Period or if the Indemnifying Party notifies the Indemnified
Party during the Direct Claim Review Period that it disputes its liability to
the Indemnified Party in respect of the underlying Claim, setting forth the
reasons for such objection, the Indemnified Party shall have one hundred eighty
(180) days after the first to occur of (x) the expiration of the Direct Claim
Review Period, and (y) the date it receives any such notification from the
Indemnifying Party, to commence arbitration proceedings against the Indemnifying
Party as provided by Section 8.7 of this Agreement. If the Indemnified Party
fails for any reason (other than impossibility at law) to so commence
arbitration proceedings within such one hundred eighty (180) day period, such
Direct Claim will be barred and the Indemnified Party shall be deemed to have
irrevocably waived its rights to pursue any other claim against the Indemnifying
Party based on the same facts, events or circumstances.


                                      -33-

<PAGE>


     7.5.4 Third Party Claims

     (A) Third Party Claim Review Period. In the event of a Third Party Claim,
the Indemnifying Party shall have thirty (30) days following its receipt of the
relevant Claim Notice (the "Third Party Claim Review Period") to make such
investigation of the underlying claim as it considers necessary or desirable and
to notify the Indemnified Party whether or not it disputes its liability to the
Indemnified Party in respect of such Third Party Claim. If the Indemnifying
Party does not notify the Indemnified Party during the Third Party Claim Review
Period that it disputes its liability to the Indemnified Party in respect of the
relevant Third Party Claim, the Indemnifying Party shall be deemed to have
acknowledged its liability to the Indemnified Party in respect of such Third
Party Claim. If the Indemnifying Party notifies the Indemnified Party during the
Third Party Claim Review Period that it disputes its liability to the
Indemnified Party in respect of the relevant Third Party Claim, setting forth
the reasons for such objection, the Indemnified Party shall have one hundred
eighty (180) days after the date it receives any such notification from the
Indemnifying Party to commence arbitration proceedings against the Indemnifying
Party as provided by Section 8.7 of this Agreement. If the Indemnified Party
fails for any reason (other than impossibility at law) to commence arbitration
proceedings within such one hundred eighty (180) day period, the Indemnified
Party's claim in respect of such Third Party Claim shall be barred and the
Indemnified Party shall be deemed to have irrevocably waived any rights to
pursue any other claims against the Indemnifying Party in respect of such Third
Party Claim.

     (B) Defense of Third Party Claim. Until such time, if any, as it is
determined or agreed that the Indemnifying Party has no liability to the
Indemnified Party in respect of a particular Third Party Claim, the Indemnifying
Party shall have the right to elect, by written notice delivered to the
Indemnified Party within fifteen (15) Business Days of receipt by the
Indemnifying Party of the Claim Notice from the Indemnified Party in respect of
the relevant Third Party Claim, at the sole expense of the Indemnifying Party,
to participate in or assume control of the negotiation, settlement or defense of
the Third Party Claim, provided that:

     (i) such will be done at all times in a diligent and bona fide matter;

     (ii) the Indemnifying Party acknowledges in writing its obligation to
indemnify the Indemnified Party (upon any eventual determination of its
liability) in accordance with, and subject to, the terms contained in this
Agreement in respect of that Third Party Claim; and

     (iii) the Indemnifying Party shall pay all reasonable out-of-pocket
expenses incurred by the Indemnified Party as a result of such participation or
assumption.

 If the Indemnifying Party elects to assume such control, the Indemnified Party
shall co-operate with the Indemnifying Party and its counsel in the defense of
such Third Party Claim and shall refrain from taking any actions which might
jeopardize or interfere with its defense. The Indemnified Party shall have the
right to participate in the negotiation, settlement or defense of any such Third
Party Claim at its own expense. If the Indemnifying Party does not so elect or,
having elected to assume such control, thereafter fails to proceed with the
settlement or defense of any such Third Party Claim, the Indemnified Party shall
be entitled to assume such control. In such case, the Indemnifying Party shall
co-operate where necessary with the Indemnified Party and its counsel in
connection with such Third Party


                                      -34-

<PAGE>


Claim and, subject to subsection (D) below, the Indemnifying Party shall be
bound by the results obtained by the Indemnified Party with respect to such
Third Party Claim.

     (C) Counterclaim and Cross-Claim. If so requested by an Indemnifying Party
and related to the claim in question, the Indemnified Party shall make (or in
the case of the Purchasers, shall cause the relevant Companies to make) any
counterclaim against any Person asserting such Third Party Claim or any
cross-claim against any other Person which may be liable. The Indemnifying Party
shall bear the cost of any such counterclaim or cross-claim, which shall not be
settled without the prior written consent of the Indemnifying Party.

     (D) Settlement of Third Party Claims. The Indemnifying Party shall not be
liable for any Third Party Claim which is settled or otherwise compromised or in
respect of which any admission of liability is made without its prior written
consent. In such connection, if the Indemnified Party shall receive from a Third
Party or if the Indemnified Party shall propose to make to a Third Party an
offer of settlement of such Third Party Claim (a "Settlement Offer"), the
Indemnified Party shall notify the Indemnifying Party of such Settlement Offer
promptly upon receipt thereof from the Third Party and reasonably in advance of
responding thereto, or reasonably in advance of making such Settlement Offer,
and shall provide with such notice all related supporting documentation
reasonably required to enable the Indemnifying Party to assess the relative
merits of the Settlement Offer. At the reasonable request of either of the
parties, the parties will consult in good faith with respect to any such
Settlement Offer. The Indemnifying Party shall then determine in the exercise of
its own reasonable business judgment whether or not to consent to the Settlement
Offer. If a Settlement Offer is received, which the Indemnifying Party, but not
the Indemnified Party, is willing to accept, the Indemnified Party may elect to
continue the defense of such claim at its own expense, in which case the
liability of the Indemnifying Party shall be limited to the lesser of: (i)
Damages calculated as if the Third Party Claim were settled in accordance with
the proposed Settlement Offer, and (ii) the Damages actually suffered by the
Indemnified Party taking into account the final determination of the Third Party
Claim. The failure by the Indemnifying Party to respond in writing to a written
request for consent to a Settlement Offer for a period of more than ten (10)
Business Days after receipt of such request by the Indemnifying Party shall be
deemed a consent by the Indemnifying Party to such request.

     7.5.5 Cooperation

     From and after the delivery of a Claim Notice hereunder, at the reasonable
request of the Indemnifying Party, the Indemnified Party shall grant the
Indemnifying Party and its representatives (including professional advisors)
reasonable access to the books, records, computerized systems, employees and
properties of the Indemnified Party (or of the Companies, if CGG is the
Indemnifying Party) to the extent reasonably related to the matters to which the
Claim Notice relates.

     7.5.6 Mitigation

     The Indemnified Party shall use its commercially reasonable efforts (and if
the Purchasers are the Indemnified Party, they shall cause the Companies to use
their commercially reasonable efforts) to mitigate any Damages resulting from
any matters giving rise to a claim for indemnification under this Article VII.


                                      -35-

<PAGE>


     7.5.7 Payment

     No amount shall become due and payable by an Indemnifying Party to an
Indemnified Party in respect of any Third Party Claim unless and to the extent
that the Indemnified Party is under the obligation to immediately pay the
relevant Damages to the relevant Third Party as a result of a final
non-appealable judgment of a court of competent jurisdiction, a final
non-appealable decision of an arbitral tribunal or a binding settlement or other
agreement among the relevant parties.

     7.5.8 Subrogation

     No amount shall become due and payable by an Indemnifying Party to an
Indemnified Party in respect of any Claim unless the Indemnified Party shall
have effectively subrogated the Indemnifying Party in all its (and the
Companies', if the Purchasers are the Indemnified Party) rights against third
parties in respect of such Claim.

7.6 Calculation of Damages
    ----------------------

     7.6.1 In calculating the amount of any Damages claimed by the Purchasers
under Section 7.4.1, there shall be deducted: (i) the amount of any
indemnification or other recoveries (including insurance proceeds) payable to
the Purchasers or any of the Companies by any third party with respect to such
Damages payment of which is not disputed by such third party, (ii) the amount of
any reserve or provision included in the Final Closing Balance Sheet for Damages
to which such Claim relates, and (iii) the amount of any corresponding Tax
savings or benefit (including any Tax reduction, credit, or loss carry-back or
carry-forward) (a "Tax Benefit") which is or will be available to the Purchasers
or any of the Companies in respect of any taxable period.

     7.6.2 For purposes of computing the amount of any Damages which an
Indemnifying Party may be required to pay hereunder, only the Damages actually
sustained by CGG, the Purchasers or the relevant Company shall be taken into
account, to the exclusion of any price/earnings or similar multiplier implicit
in the Purchase Price.

     7.6.3 If at the time that a Claim is made by a Purchaser or a payment is
required to be made by CGG in respect of any Damages suffered or incurred by the
Companies, the availability or the amount of any corresponding Tax Benefit
cannot be determined with reasonable certainty, the potential Tax Benefit shall
not then be taken into account in the computation of the amount of Damages
payable by CGG and any required payment shall not be delayed. Thereafter, the
Purchasers shall cause the Companies to notify CGG with reasonable promptness
whenever a Tax Benefit is claimed by or on behalf of the Companies (or their tax
group) or its availability becomes reasonably certain as a result of the Damages
suffered or incurred by the Companies relating to such Claim, which notice shall
indicate the amount of such Tax Benefit. CGG shall also have the right, at any
time after a Claim is made in respect of which the availability of the Tax
Benefit of the corresponding Damages cannot be determined with reasonable
certainty, to require that its auditors be given reasonable access to the
relevant accounting and tax records of the Companies to determine the
availability and amount of any such Tax Benefit.

     7.6.4 In the event that the amount of any deduction referred to in this
Section 7.6 is determined only after payment by CGG of the amount otherwise
required pursuant to this


                                      -36-

<PAGE>


Article VII, Paradigm shall repay to CGG promptly after such determination any
such payments that CGG would not have had to make pursuant to this Article VII
had such determination been made at or prior to the time of such payment.

     7.6.5 In calculating the amount of Damages claimed by CGG under Section
7.4.2, there shall be deducted therefrom the amount of any Tax Benefit which is
or will be available to CGG in respect of any taxable period (following the same
principles and procedures set forth in Section 7.6.3 as if CGG were the
Purchaser and the Purchaser were CGG), provided that the payment made in respect
of the corresponding Claim is not taxable to CGG.

7.7 Additional Rules and Procedures
    -------------------------------

     The obligations of CGG and the Purchasers to indemnify each other pursuant
to this Article VII shall also be subject to the following limitations and
exclusions:

     7.7.1 An Indemnified Party shall only be entitled to make a Claim pursuant
to this Article VII in respect of a representation or warranty contained in this
Agreement if a Claim Notice is properly given within the time periods provided
for in Sections 7.1 and 7.2, as the case may be;

     7.7.2 No Claim may be made by the Purchasers or CGG, and no amount shall be
due by CGG or the Purchasers in respect of any such Claim, unless and only to
the extent that after application of the provisions of this Article VII:

     (A) the amount of Damages in respect of which the relevant party is
entitled to be indemnified as a result of any individual claim exceeds $50,000;
and

     (B) the cumulative and aggregate amount of all Damages in respect of which
the relevant party is obligated to indemnify the other party under the preceding
clause (A) exceeds $250,000.

Notwithstanding the foregoing, as between the parties, the foregoing limitations
constitute deductibles and CGG, on the one hand, and the Purchasers, on the
other hand, shall be liable to indemnify each other only for Damages in excess
of such amounts.

     7.7.3 (A) Except for those circumstances where CGG has made any fraudulent
or intentional misrepresentation or breach with respect to any of its
representations, warranties, agreements or covenants contained in this
Agreement, and notwithstanding any other provision in this Agreement, in no
event shall the aggregate amount of Damages for which the Purchasers
(collectively) may claim hereunder, and for which CGG may be liable, exceed
Seven Million US Dollars (US$7,000,000).

     (B) Except for those circumstances where any of the Purchasers has made any
fraudulent or intentional misrepresentation or breach with respect to any of its
respective representations, warranties, agreements or covenants contained in
this Agreement, and notwithstanding any other provision in this Agreement, in no
event shall the aggregate amount of Damages for which CGG may claim hereunder,
and for which the Purchasers (collectively) may be liable, exceed Five Million
US Dollars (US$5,000,000).


                                      -37-

<PAGE>


     7.7.4 No claim in respect of Taxes shall entitle the Purchasers to
indemnification if it corresponds to a mere change in the time when a Tax should
have been paid or if such Tax can effectively be deducted or recovered by the
relevant Company (except that the Purchasers shall be entitled to be indemnified
in accordance herewith for any resulting interest charges or penalties for late
payment).

     7.7.5 CGG shall have no liability to the Purchasers for Damages which arise
as a direct result of: (w) any act or omission of the Purchasers or the
Companies having as its purpose the precipitation of a claim for indemnification
hereunder, (x) any changes in accounting methods or policies, (y) the granting
of any extensions or waivers with respect to any statute of limitations
applicable to claims which might be made against the Purchasers or the
Companies, or (z) the passing of, or any change in, after the Closing, any Law
or administrative practice of any Governmental Authority in any such case not
actually in force at the date of this Agreement (even if retroactive in effect),
including, but not limited, to any increase in the Tax rates in effect on the
date hereof or imposition of any Tax not in effect on the date hereof.

     7.7.6 Notwithstanding anything in this Agreement to the contrary, a claim
for Damages resulting from an inaccuracy or breach of the representations and
warranties of CGG set forth in Sections 3.1.14 and 3.1.17 (even if such
inaccuracy or breach could also constitute an inaccuracy or breach of any other
representations and warranties of CGG set forth in this Agreement) shall give
rise to an indemnification obligation under this Article VII only if it is based
on a successful Third Party Claim duly and timely notified to CGG.

     7.7.7 Neither CGG, on the one hand, nor the Purchasers, on the other hand,
shall be required to indemnify any other more than once on account of the same
facts, matters or circumstances, and neither CGG, on the one hand, nor the
Purchasers, on the other hand, shall be entitled to make any claim for
indemnification in connection with Damages arising out of or resulting from
facts or circumstances of which it was aware at the time of Closing.

7.8 Treatment of CGG's Indemnification Payments. Notwithstanding the use of the
term "indemnification" herein with respect to CGG's obligations under this
Article VII, the parties agree that any payments made by CGG or received by the
Purchasers pursuant to this Article VII shall be deemed to constitute a partial
repayment and adjustment of the Purchase Price, and agree to treat (and to cause
their Affiliates to treat) any such payments as a partial repayment of the
Purchase Price for all tax, accounting and financial reporting purposes.

                                  ARTICLE VIII

     8.1.1 CGG represents and warrants to the Purchasers that neither it nor
