Reorganization (the "Merger Agreement"; terms used but not defined in this
                     ----------------
Agreement shall have the meanings ascribed to them in the Merger Agreement),
which provides, upon the terms and subject to the conditions thereof, for, among
other things, the merger of Merger Sub with and into the Company;

          WHEREAS, certain shareholders of the Company own such number of shares
of common stock, no par value, of the Company ("Common Stock") as is set forth
                                                ------------
on Exhibit A hereto; and

enter into the Merger Agreement and incur the obligations set forth therein,
Parent has required that the Individual Shareholders agree, and in order to
induce Parent and Merger Sub to enter into the Merger Agreement, each Individual
Shareholder has agreed, to enter into this Agreement with respect to all shares
of Common Stock now owned and which may hereafter be acquired by the Individual
Shareholders (the "Shares");
                   ------
          NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth in this
Agreement and in the Merger Agreement, the parties hereto agree as follows:

                                   ARTICLE I

                               VOTING OF SHARES
                               ----------------
          SECTION 1.01. Vote in Favor of Merger; Grant of Proxy. (a) During the
                        ---------------------------------------
period commencing on the date hereof and terminating at the Effective Time, each
Individual Shareholder, solely in his or her capacity as a shareholder of the
Company, agrees to vote (or cause to be voted) all shares of Common Stock
currently beneficially owned by such Individual Shareholder, and all shares of
Common Stock which such Individual Shareholder acquires in the future, at any
meeting of the shareholders of the Company, and in any action by written consent
of the shareholders of the Company, (i) in favor of the approval, consent,
ratification and adoption of the Merger Agreement and the Merger, and (ii)
against any action that would materially impede, interfere, or discourage the
Merger, and, other than the Merger and the transactions contemplated by the
Merger Agreement, against any merger, consolidation or other business
combination involving the Company, against any recapitalization, reorganization,
dissolution or liquidation of the Company and against any extraordinary
corporate transaction involving a disposition of 50% or more of the assets of
the Company, and against any action that would result in any material breach of
representation, warranty, covenant, or agreement of the Company under the Merger
Agreement.

          (b)  Each Individual Shareholder, solely in his or her capacity as a
shareholder of the Company, also hereby constitutes Parent, or any nominee of
Parent, with full power of substitution, as such Individual Shareholder's
irrevocable proxy and attorney-in-fact to vote and otherwise act (by written
consent or otherwise) with respect to such Individual Shareholder's shares of
Common Stock as indicated in Section 1.01(a) in the event that such Individual
Shareholder fails to comply with its obligations under such section. Each
Individual Shareholder intends this proxy to be irrevocable and coupled with an
interest and will take such further action and execute such other instruments as
may be necessary to effectuate the intent of this proxy. To the extent
inconsistent with the foregoing provisions of this Section 1.01, each Individual
Shareholder hereby revokes any and all previous proxies with respect to any
shares of Common Stock that such Individual Shareholder owns or has the right to
vote.

          (c)  Notwithstanding anything in this Agreement to the contrary, no
Individual Shareholder shall be required to exercise any option or convert any
Company security into Common Stock.

Sub solely with respect to himself that:

          (a)  Holdings. He is the lawful record and beneficial owner of
the number of shares of Common Stock set forth on Exhibit A of this Agreement,
free and clear of all encumbrances, and, except as contemplated by this
Agreement, he is not a party to any voting trust, shareholder agreement, proxy

          (b)  Capacity; No Conflict. He has the legal capacity to enter into
this Agreement and to consummate the transactions contemplated hereby. This
Agreement has been duly executed and delivered by such Individual Shareholder,
and, assuming the due authorization, execution and delivery by Parent, this
Agreement constitutes a legal, valid and binding obligation of such Individual
Shareholder. The execution and delivery of this Agreement does not, and the
consummation of the transactions contemplated hereby will not, conflict with, or
result in any violation of, or default under (with or without notice or lapse of
time, or both), or give rise to a right of termination, cancellation or
acceleration of any obligation or loss of a benefit under any material mortgage,
indenture, lease, contract or other agreement or instrument, permit, concession,
franchise, license, judgment, order, decree, statute, law, ordinance, rule or
regulation applicable to such Individual Shareholder or such Individual
Shareholder's properties or assets. No consent, approval, order or authorization
of, or registration, declaration or filing with, any governmental body, agency,
official or authority is required by or with respect to such Individual
Shareholder in connection with the execution and delivery of this Agreement by

of the transactions contemplated hereby, except for (i) any filings as may be
required under applicable U.S. or state securities laws and the securities laws
of any foreign country and (ii) such other consents, authorizations, filings,
approvals and registrations which, if not obtained or made, would not prevent or
materially alter or delay any of the transactions contemplated by this
Agreement.

          (c)  Litigation. There is no private or governmental action, suit,
proceeding, claim, arbitration or investigation pending before any agency, court
or tribunal, foreign or domestic, or, to the knowledge of such Individual
Shareholder or any of his affiliates, threatened against such Individual
Shareholder or any of his affiliates or


                                       4

any of their respective properties or any of their respective officers or
directors, in the case of a corporate entity (in their capacities as such) that,
individually or in the aggregate, could reasonably be expected to have a
material adverse effect on his ability to consummate the transactions
contemplated by this Agreement. There is no judgment, decree or order against
such Individual Shareholder or any of his affiliates or, to the knowledge of
such Individual Shareholder or any of his affiliates, any of their respective
directors or officers, in the case of a corporate entity (in their capacities as
such) that could prevent, enjoin, alter or materially delay any of the
transactions contemplated by this Agreement, or that could reasonably be
expected to have a material adverse effect on such Individual Shareholder's
ability to consummate the transactions contemplated by this Agreement.

          Parent hereby represents and warrants to the Individual Shareholders

          SECTION 3.01. Authority Relative to This Agreement. Parent is a
                        ------------------------------------
corporation duly incorporated and validly existing under the laws of France. The
execution, delivery and performance by Parent of this Agreement and the
consummation by Parent of the transactions contemplated hereby are within
Parent's corporate powers and have been duly authorized by all necessary
corporate action. This Agreement has been duly and validly executed and
delivered by Parent and, assuming the due authorization, execution and delivery
by the Individual Shareholders, constitutes a valid and binding agreement of
Parent enforceable against Parent in accordance with its terms.

          SECTION 3.02. No Conflict; Required Filings and Consents. (a) The
                        ------------------------------------------

consummation by Parent of the transactions contemplated hereby require no action
by or in respect of, or filing with, any governmental body, agency, official or
authority, whether federal, state, multinational (including, but not limited to,
the European Community), provincial, municipal, domestic or foreign, (insofar as
such action or filing relates to Parent) other than (i) compliance with any
applicable requirements of the HSR Act, the EC Merger Regulations, any foreign
laws regulating competition or antitrust, or the Exchange Act, (ii) approvals
and authorizations of self-regulatory and governmental organizations in the
securities and commodities field, and (iv) such other consents, approvals and

aggregate, have a material adverse effect on Parent or materially impair the
ability of Parent to consummate the transactions contemplated hereby.

Agreement and the consummation by Parent of the transactions contemplated hereby
do

not and will not (i) contravene or conflict with the organizational documents of
Parent, (ii) assuming receipt of or compliance with all matters referred to in
Section 3.02(a), contravene or conflict with or constitute a violation of any

upon or applicable to Parent or (iii) constitute a breach of or a default under
or give rise to a right of termination, cancellation or acceleration of any
right or obligation of Parent or to a loss of any benefit to which Parent is
entitled under any provision of any agreement, contract or other instrument
binding upon Parent or any license, franchise, permit or other similar
authorization held by Parent, other than, in the case of each of (ii) and (iii),
any such items that, individually or in the aggregate, would not have a material
adverse effect on Parent or materially impair the ability of Parent to
consummate the transactions contemplated by this Agreement.


                                  ARTICLE IV

                                 MISCELLANEOUS

                        --------------------
Agreement may be amended or waived if, and only if, such amendment or waiver is
in writing and signed, in the case of an amendment, by each Individual
Shareholder and Parent or in the case of a waiver, by the party against whom the
waiver is to be effective.

          (b)  No failure or delay by any party in exercising any right, power
or privilege hereunder shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
provided shall be cumulative and not exclusive of any rights or remedies
provided by law.

          SECTION 4.02. Fees and Expenses. Except as otherwise provided herein,
                        -----------------

telecopy, facsimile, cable, telegram or telex, or by registered or certified
mail (postage prepaid, return receipt requested) or by a nationally recognized
courier service to the respective parties at their addresses as specified in
Exhibit B hereto.

          SECTION 4.04. Severability. If any term or other provision of this
                        ------------
Agreement is invalid, illegal or incapable of being enforced by any rule of law
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in


                                       6

full force and effect so long as the economic or legal substance of this
Agreement is not affected in any manner materially adverse to any party. Upon
such determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties hereto shall negotiate in good faith to
modify this Agreement so as to effect the original intent of the parties as
closely as possible in a mutually acceptable manner in order that the terms of
this Agreement remain as originally contemplated to the fullest extent possible.

                        --------------------
irreparable damage would occur in the event any provision of this Agreement was
not performed in accordance with the terms hereof, that the parties hereto would
not have an adequate remedy at law for money damages in such event and that the
parties shall be entitled to specific performance of the terms hereof, in
addition to any other remedy at law or in equity.

          SECTION 4.07. Governing Law; Submission to Jurisdiction. (a) This
                        -----------------------------------------
Agreement shall be governed by the Laws of the State of California as applied to
contracts executed and to be performed entirely in such state.

          (b)  Each Individual Shareholder and Parent hereby irrevocably submits
to the non-exclusive jurisdiction of any California State court or any Federal
court sitting in the state of California in any action or proceeding arising out
of or relating to this Agreement, and each Individual Shareholder hereby
irrevocably agrees that all claims with respect to any such action or proceeding
may be heard and determined in such California State court or in such Federal

fullest extent it may effectively do so, the defense of an inconvenient forum to
the maintenance of such action or proceeding.

all of which taken together shall constitute one and the same agreement.


                                       7

          SECTION 4.10. Entire Agreement. This Agreement and, to the extent
                        ----------------
referred to herein, the Merger Agreement, constitute the entire agreement
between the parties with respect to the subject matter hereof and supersede all
prior agreements and understandings, both written and oral, between the parties,
or any of them, with respect thereto; provided, however, that any capitalized
                                      --------  -------
terms used but not defined herein shall have the meanings ascribed to such terms
in the Merger Agreement. No addition to or modification of any provision of this
Agreement shall be binding upon either party hereto unless made in writing and
signed by the parties hereto.


                                       8
