2. SALE AND PURCHASE

The Sellers hereby agree to sell and the Purchaser hereby agrees to purchase all, but not part only, of the Shares at Completion, free from any Encumbrances but with all rights attached to such Shares at the date hereof or subsequently becoming attached to them.

3. CONSIDERATION

3.1 Purchase Price

3.1.1 The aggregate consideration (the “Purchase Price”) for the sale of the entirety of the Shares shall be the sum of US $20,000,000 in cash, representing US $20,000,000 less (i) any Company Expenses shown on the Statement of Expenses and (ii) any Cash Deficit shown on the Statement of Cash Deficit as such terms are defined hereafter. The Purchase Price shall be allocated to the Sellers as set forth on the Completion Schedule attached as SCHEDULE 2 (the “Completion Schedule”).

3.1.2 The portion of the Purchase Price payable to each Seller less the applicable Holdback Amount shall be transmitted by Purchaser by immediate day IBAN or SWIFT electronic transfer to each Seller, free of any costs or expenses from the Purchaser’s bank, at the bank account set forth on the Completion Schedule (such amount the “Net Amount due at Closing” as set forth with respect to each Seller on the Completion Schedule). Each Seller confirms that such account information is accurate and that Purchaser shall have no liability for any inaccuracy or failure of such bank accounts to receive the Purchase Price transmitted by Purchaser to such account. The Holdback Amount shall be retained by Purchaser pursuant to clause 6.

3.1.3 “Company Expenses” shall mean all costs and expenses (including attorney’s fees) incurred in connection with the Letter Agreement dated March 17, 2005 between Purchaser, the Company and the Sellers (the “Letter Agreement”), this Agreement, any related agreements and the transactions contemplated hereby and thereby incurred by the Company, but shall exclude an aggregate of EUR 15,000. The estimated amount of Company Expenses shall be set forth on SCHEDULE 6 (the “Statement of Expenses”) and shall be delivered by the Sellers’ Representative to Purchaser three days prior to the Completion Date along with copies of the documents or instruments evidencing the amounts set forth on the Statement of Expenses. In preparing such Statement of Expenses, the Sellers’ Representative shall use its good faith best efforts to include all Company Expenses then known or reasonably estimable, and shall certify that, to the best of the Sellers’ Representative’s knowledge, such Statement of Expenses includes all of the Company Expenses paid, payable or to become payable at any time prior to, at or following the Completion Date, it being the Parties express intent that to the maximum extent possible all the Company Expenses be deducted from the Purchase Price and that there be no Indemnifiable Company Expenses. Any Company Expenses which have not been set forth in the Statement of Expenses and therefore not deducted from the Purchase Price pursuant to Section 3.1.1 are collectively referred to as “Indemnifiable Company Expenses” and shall constitute “Losses” for purposes of claims pursuant to clause 6.

3.1.4 The amount, if any, by which the Company’s debt and other Liabilities (including all Liabilities that may arise as a result of the Completion, including the repayment of any subsidies, other government grants or operating leases) exceeds the Company’s unencumbered cash (i.e. the

“actif circulant” as defined in the Accounts) as of the Completion shall be referred to as the “Cash Deficit”. The amount of Cash Deficit shall be set forth on SCHEDULE 7 (the “Statement of Cash Deficit”). The Statement of Cash Deficit shall be delivered by the Sellers’ Representative to Purchaser three days prior to the Completion Date along with copies of the documents or instruments evidencing the amounts set forth on the Statement of Cash Deficit. In preparing such Statement of Cash Deficit, the Sellers’ Representative shall use its good faith best efforts to include all Liabilities and obligations then known or reasonably estimable, and shall certify that, to the best of the Sellers’ Representative’s knowledge, such Statement of Cash Deficit is accurate, it being the Parties express intent that to the maximum extent possible that any Cash Deficit be deducted from the Purchase Price and that there be no Indemnifiable Cash Deficit. Any Cash Deficit which has not been set forth in the Statement of Cash Deficit and therefore not deducted from the Purchase Price pursuant to Section 3.1.1 is referred to as “Indemnifiable Cash Deficit” and shall constitute “Losses” for purposes of claims pursuant to clause 6. In no event shall the Purchase Price be increased, even if the Company’s unencumbered cash exceeds Company’s debt and other Liabilities.

3.1.5 All payments hereunder, whether pursuant to clause 3 or clause 6 or otherwise, shall be payable in US dollars.

3.1.6 The Sellers agree that the conversion rate of US dollars into Euros shall be $1.20 US dollars per Euro for purposes of determining the allocation of the Purchase Price pursuant to clause 3.1.1. For all other purposes, any amounts denominated in Euros shall be converted into US dollars at the conversion rate in effect at the close of the US market on the later of (a) the Indemnification Date or (b) the third day prior to the payment of US dollars pursuant to this Agreement.

4. COMPLETION

4.1 Completion Date

Completion shall be deemed to occur at the offices of the Sellers’ counsel, Cap Code, société d’avocats, 19 A rue de Châtillon, 35000 Rennes (France), on May 11, 2006 (the “Completion Date”).

4.2 Pre-Completion and Completion Deliveries

4.2.1 At least three days prior to the Completion Date the Sellers’ Representative shall deliver to Purchaser (i) the Statement of Company Expenses and (ii) the Statement of Cash Deficit along with copies of the documents or instruments evidencing the amounts set forth on such Statements in accordance with sub-clauses 3.1.3 and 3.1.4.

(E) the resignation letter of the President of the Company, effective on the date of the shareholder meeting called to replace him, provided that his employment contract is executed by the new Company’s representative on the Completion date;

(F) employment agreements signed by the individuals listed in SCHEDULE 8 in a form satisfactory to the Purchaser, to be executed by the new Company’s representative on the Completion date;

(G) all other documents useful or necessary for completion of the sale to the Purchaser of the Shares and completion of all other transactions contemplated herein, and all documents evidencing the performance by the Sellers of their undertakings hereunder, which the Purchaser may reasonably request;

(H) the fully-executed short-form share purchase agreement in the form set forth in SCHEDULE 4 (for the sole purpose of registering the sale of the Shares with the Tax authorities; in the event of any conflict between the terms of such short-form share purchase agreement and this Agreement, the terms of this Agreement shall control);

(I) a certified copy of the shareholder meeting minutes for the Company, at which:

(5) all existing mandates for the operation of the bank accounts of the Company shall be revoked except that Françoise Eveno shall retain her current authority to initiate transactions;

(6) Ernst & Young Audit shall be appointed principal statutory auditor of the Company and Auditex shall be appointed alternative auditor of the Company; and

(7) the reimbursement of the shareholders’ current accounts (which amounts are reflected as Liabilities of the Company in determining the Statement of Cash Deficit and consist solely of EUR 8,750 owed by the Company to Bernard Badefort and EUR 8,750 owed by the Company to Jean-Marc Guyot) within 15 days shall have been approved.

4.2.3 All matters at Completion are considered as taking place simultaneously, and no delivery of any document will be deemed complete until all transactions and deliveries of documents required by this Agreement have taken place. In particular, the sale and purchase of the Shares hereunder may not take place unless and until the employment agreements have each and all been duly executed.

5. WARRANTIES

5.1 Sellers’ Warranties

Each Seller represents and warrants to the Purchaser that, as of the Completion Date, each of the Warranties is true and accurate in all respects and is not misleading.

5.2 Purchaser’s Warranties

The Purchaser represents and warrants to each of the Sellers that, as of the Completion Date, the Purchaser is a company duly organised and validly existing and in good standing under the laws of its jurisdiction of organisation and that the Purchaser has all requisite corporate power and authority to enter into and perform this Agreement, including the due authorization of its sole shareholder.

6. INDEMNIFICATION

6.1 Indemnity

The Purchaser and the Sellers acknowledge that only the Individual Sellers shall be liable for the indemnification under clause 6 of this Agreement.

The representations, warranties and covenants of the Sellers set forth in this Agreement shall survive the Completion and remain in full force and effect. “Losses” of any person or entity means any and all demands, claims, suits, actions, causes of action, proceedings, assessments, losses, damages, Liabilities, earnings shortfall, interest, penalties, taxes, costs and expenses incurred, or reasonably expected to be incurred, by such person or entity, including interest, penalties and attorneys’ fees, third party expert and consultant fees and expenses, fines, judgments, awards and financial responsibility for investigation, removal and cleanup costs, natural resource damages, government oversight costs and costs for redesign and rework of technology, and reasonable fees and expenses incurred in connection with the enforcement of the rights of any Indemnified Person pursuant to this Agreement. The term Losses as used herein is not limited to matters asserted by third parties, but includes Losses incurred or sustained in the absence of claims by a third party. Each Individual Seller undertakes to indemnify the Purchaser and the Company

(collectively, the “Indemnified Person(s)”) from and against any and all Losses asserted against, imposed upon, or incurred by such Indemnified Person which arise out of or in connection with:

6.1.1 any Warranty being untrue, inaccurate or incomplete;

6.1.2 any increase in the Liabilities (including undisclosed Liabilities) of the Company as at the Completion Date, which increase does not fully appear in the Accounts, any loss or damage suffered by the Purchaser or the Company based on or arising out of an event or circumstance occurring or existing prior to the Completion Date, whether known or unknown by the Sellers and/or the Company and which has not been specifically addressed, reserved against or allowed for, or has been insufficiently addressed, reserved against or allowed for, in the Accounts.

6.1.3 any Indemnifiable Cash Deficit based on or arising out of an event or circumstance occurring or existing on or prior to the Completion Date, whether known or unknown by the Sellers and/or the Company;

6.1.4 any Indemnifiable Company Expenses based on or arising out of an event or circumstance occurring or existing on or prior to the Completion Date, whether known or unknown by the Sellers and/or the Company; and

6.1.5 any fraud, intentional misrepresentation, wilful misconduct or wilful concealment by the Company or the Sellers occurring or existing on or prior to the Completion Date.

Any potential Indemnification Liability shall be calculated without giving effect to qualifications as to “materiality” contained in the Warranties. For clarity, the amount of Losses shall not be adjusted to reflect any tax deduction or similar tax benefit received by an Indemnified Person as a result of such Loss. Each Individual Seller shall bear his or her portion of any Indemnification Liability pro rata in proportion to such Individual Seller’s number of shares set forth in the column titled “Individual Sellers number of shares” on the SCHEDULE 2 (Completion Schedule) relative to the Total set forth at the bottom of such column.

6.2 Time Limits

Any “Claim” shall be made by notice in writing to the Sellers’ Representative, at the latest (i) before the ending of the month following the ending of the applicable legal term of limitation (“prescription légale”) for any and all Losses that arise out of or in connection with any Warranty set forth in Articles 1 (Corporate Organisation and Business), 2 (Shareholdings), 18 (Taxation), 19 (Employment) or 25 (The Individual Sellers) of SCHEDULE 3 being untrue, inaccurate or incomplete or for any Losses arising out of or in connection with any fraud, intentional misrepresentation, wilful misconduct or wilful concealment by the Company or the Sellers occurring or existing on or prior to the Completion Date, and (ii) before the third anniversary of the Completion Date for any other Losses. For the avoidance of doubt, provided that notice of any Claim is given within the applicable time limit, the rights of the Indemnified Person under this Clause 6 with respect to such Claim shall survive until such time as such Claim is finally resolved.

6.3 Limitation on Indemnification

6.3.1 Basket and Deductible

The Indemnified Persons shall not be entitled to indemnification pursuant to clause 6 unless the aggregate amount of Losses exceeds $400,000 (which amount is referred to as the “Losses Threshold”), at which point the Individual Sellers shall be obligated to indemnify the Indemnified Persons under this clause 6 for all Losses (including Losses constituting the Losses Threshold other than the first $200,000 of such Losses Threshold (the “Deductible”)).

6.3.2 Cap

For the purposes of this Agreement:

“Period 1” shall mean the period extending from the Completion Date through the first anniversary of the Completion Date, and

“Period 2” shall mean the period extending from the expiration of Period 1 through the second anniversary of the Completion Date, and

“Period 3” shall mean the period extending from the expiration of Period 2 and continuing until no further Claim can be made as a result of the expiration of all time periods set forth in clause 6.2.

The Individual Sellers’ aggregate Indemnification Liability with respect to Claims made by an Indemnified Person during Period 1 shall be limited to 40% of the Purchase Price.

The Individual Sellers’ aggregate Indemnification Liability with respect to Claims made by an Indemnified Person during Period 2 shall be limited to 30% of the Purchase Price minus the amount of Losses previously indemnified hereunder with respect to Period 1.

The Individual Sellers’ aggregate Indemnification Liability with respect to Claims made by an Indemnified Person during Period 3 shall be limited to 20% of the Purchase Price minus the amount of Losses previously indemnified hereunder with respect to Period 1 and Period 2.

6.3.3 No Cap on Fraud

Notwithstanding anything to the contrary herein, there shall be no limitation on Indemnification Liability for Losses which arise out of or in connection with any fraud, intentional misrepresentation, wilful misconduct or wilful concealment by the Company or the Sellers.

6.4 Indemnification Procedure and Payment

6.4.1 Implementation of the Indemnification Procedure

(A) Subject to the terms of sub-clauses 6.2 and 6.4.4, an Indemnified Person shall be entitled to make a Claim against the Individual Sellers by delivery of notice to the Sellers’ Representative at any

time after the Indemnified Person becomes aware of any fact that could give rise to Indemnification Liability.

(B) If the Sellers’ Representative disputes the basis or the amount of the Claims made by the Indemnified Person, the Sellers’ Representative shall notify such Indemnified Person within 30 days following receipt of the Claim notice. Failure to make such a dispute notification within this time limit shall result in the dispute being disallowed and the Individual Sellers being deemed to have agreed to the basis and amount of the relevant Claims on the date of expiry of such time limit.

6.4.2 Disputed Claims

In the event that a Claim is disputed by the Individual Sellers within the time limit set forth in Section 6.4.1(B):

(A) the Indemnified Person and the Sellers’ Representative shall endeavour to reach agreement in respect of the disputed points relating to a Claim within 30 days after the date on which the Sellers’ Representative made a dispute notification; or

(B) in the absence of such agreement within such 30 days, either Party may refer the matter for resolution pursuant to Clause 11.

6.4.3 Payment Obligation

(A) Indemnification Payment – Any amount payable by any Individual Seller to any Indemnified Person under this Clause 6 shall be payable within 30 days from the date of quantification of the Indemnification Liability by mutual agreement or pursuant to an arbitration decision (such due date, the “Indemnification Date”) provided, the occurrence of the Indemnification Date shall be considered in itself as formal notice (mise en demeure) to pay the relevant Indemnification Liability and such amount shall bear interest at an annually compounded rate per annum equal to lower of (a) EURIBOR 3 month plus 3% from the Indemnification Date or (b) the maximum rate permitted by applicable law.

(B) Specific cases – As a limited exception to the general principle set out in paragraph (A) above, the Indemnification Date shall:

(1) if the Claim made by the Indemnified Person is based on a claim by a third party (other than the Tax authorities) against the Purchaser, the Company or the successor to the whole or any part of the Company’s business, be the date on which the amount due by the Purchaser, the Company or the successor becomes payable, it being agreed that in the event of litigation with respect to the relevant third party claim, this date shall be the date on which an enforceable judgement was issued; or

(2) if the Claim made by the Indemnified Person is based on a claim made by the Tax authorities against the Purchaser, the Company

or the successor to the whole or any part of the Company’s business, be the date on which the amount claimed is subject to a notice from the Tax authorities demanding payment, it being agreed that in the event that the Individual Sellers wish to contest the said notice demanding payment, the Individual Sellers shall be bound to advance the amount of security claimed by the Tax authorities for the purposes of this claim.

(C) Payment Process – With respect to each Claim, the Indemnified Person shall receive payment out of the Holdback Amount equal to the amount of such Claim. The Indemnified Person shall have the obligation to receive payment out of the Holdback Amount before requiring any payment directly from the Individual Sellers.

6.4.4 Conduct of Proceedings

If any Indemnified Person becomes aware of any third party claim against the Purchaser, the Company or the successor to the whole or any part of the Company’s business (including any notification of a Tax audit) after Completion and if this claim is, in the opinion of such Indemnified Person, likely to give the Indemnified Persons the right to make a Claim against the Individual Sellers:

(A) the Indemnified Person shall promptly give notice to the Sellers’ Representative of this third party claim, provided that any delay in making such a claim shall reduce the Indemnification Liability only by the extent of the damage effectively suffered by the Individual Sellers as a result of such delay;

(B) the Sellers’ Representative may within a period of 30 days from the date of receipt of the notice mentioned in paragraph (a) above or sooner, in the event of urgent proceedings or Tax proceedings, provide the Purchaser with the name of the representative responsible for attending, on behalf of the Sellers’ Representative and at the Sellers’ Representative’s cost, the proceedings relating to such third party claim, provided that the Sellers’ Representative undertakes to indemnify the Indemnified Person against any losses, costs, damages and expenses resulting therefrom. The Indemnified Person shall consult with any such representative to the extent commercially reasonable and to the extent such consultation would not jeopardize the Indemnified Persons rights with respect to maintenance of the attorney/client privilege or otherwise. Any failure to consult shall reduce the Indemnification Liability only by the extent of the damage effectively suffered by the Individual Sellers as a result of such failure;

(C) notwithstanding the appointment of a representative by the Sellers or any other provision of this Agreement, the Indemnified Person shall be entitled to assume the defence of such third party claim and shall be free to take any action that it deems to be in the interest of the Indemnified Person (including instigating, continuing or ceasing any arbitration or court proceedings, or reaching a settlement).

6.5 Sellers Acknowledgements

6.5.1 The Individual Sellers acknowledge and agree that the rights of the Indemnified Person to indemnification pursuant to Clause 6 is an essential part of the economic terms of this Agreement.

6.5.2 The Individual Sellers shall not be released from their obligations under this Clause 6 as a result of (i) such Individual Seller’s lack of awareness of the situation resulting in a Claim or (ii) any knowledge that the Purchaser has or may have of said situation, including as a result of any investigations made by the Purchaser, its representatives or its counsel, prior to the Completion Date.

6.5.3 The Individual Sellers shall be exempted from Indemnification Liability only as regards events or facts set forth in the Disclosures to the extent:

(A) any such Disclosure shall clearly describe the identified matter and include all appropriate information and/or documents so as to reasonably ascertain the nature of such matter and quantify the relevant risk;

(B) any Disclosure set forth in an Exhibit shall qualify only the Warranty to which such Exhibit corresponds (and the Purchaser shall not be considered as having knowledge or notice of any matter pertaining to the Company which is not set forth in the relevant Exhibit);

(C) any such Disclosure shall qualify the Warranties only to the extent of the amount specified for such Disclosure in the relevant Exhibit; and

(D) the Individual Sellers shall be unable to make any further Disclosures subsequent to the date hereof.

6.5.4 The approval of the annual accounts for any fiscal year by the shareholders’ meeting of the Company shall have no effect on any potential Indemnification Liability.

6.6 Holdback Distribution

The “Holdback Distribution Date” shall mean the third anniversary of the Completion Date. On the Holdback Distribution Date, Purchaser will distribute any portion of the Holdback Amount that (a) has not previously been paid to an Indemnified Person and (b) is not subject to a pending Claim (in such case, only the estimated potential Loss shall be retained). Any amount not distributed on the Holdback Distribution Date shall be distributed to the Indemnified Persons or Individual Sellers, as applicable, within 30 days following the last to occur of the final resolution and payment of any Indemnification Liability pursuant to clause 6, if any.

All such distributions of Holdback Amounts will be made pro rata in proportion to the relative Holdback Amount originally held back with respect to each Individual Seller pursuant to column titled “Original Holdback Amount” within the SCHEDULE 2. Such distribution shall be made to the accounts set forth on the Completion Spreadsheet (as the account information may have been altered at the written request of each applicable

Individual Seller to Purchaser) and Purchaser shall be entitled to rely on such Completion Spreadsheet as accurate for all purposes and shall have no liability for any failure of the Individual Seller to receive any amount properly transmitted by Purchaser in accordance with such Completion Spreadsheet.

6.7.3 The Sellers’ Representative shall not be liable, responsible or accountable in damages or otherwise to the Individual Sellers for any loss or damage incurred by reason of any act or failure to act by such Sellers’ Representative, and each Individual Seller shall indemnify and hold harmless the Sellers’ Representative against any loss or damage except to the extent that such loss or damage shall have been the result of the individual gross negligence or wilful misconduct of such Sellers’ Representative.
