The Aggregate Consideration shall be allocated as follows: (a) the Aggregate Cash Amount for 1,420,000 Company Shares corresponding to 0.97% of the Company’s issued share capital (the “Cash Shares”) and (b) 3,506,173 Purchaser Shares (the “Share Consideration”) for 5,680,000 Company Shares corresponding to 3.87% of the Company’s issued share capital (the “Exchanged Shares”).

2.2

Cash Closing.

(a) The consummation of the sale and purchase of the Cash Shares pursuant to the terms of this Agreement (the “Cash Closing”) shall take place at (i) the Zurich offices of Homburger, as soon as reasonably practicable but no later than five (5) Business Days following the satisfaction or waiver of all conditions set forth in Article VI below (other than those conditions that by their nature are to be satisfied as of the Cash Closing Date, but subject to the fulfilment or waiver of those conditions as of the Cash Closing Date) in accordance with this Agreement or (ii) at such other time and place as the Parties may mutually agree in writing. The date on which the Cash Closing occurs is called the “Cash Closing Date”.

(b) At the Cash Closing, the Seller shall deliver, or cause to be delivered, to the Purchaser (i) a valid assignment of the Cash Shares in writing with written notice to the Company to that effect (provided, however, that the time of delivery of such notice to the Company shall have to be agreed by the Purchaser) and evidence of a book transfer of the Cash Shares to the Purchaser through SIS (Lieferung gegen Zahlung) and (ii) a Seller’s Certificate dated as of the Cash Closing Date, and shall do all such other acts as may be required under Applicable Law and the articles of incorporation of the Company to transfer the Cash Shares and all rights connected therewith to the Purchaser.

(c) At the Cash Closing, the Purchaser shall (i) pay to the Seller an amount equal to the Aggregate Cash Amount in cash by wire transfer in immediately available funds to a bank account designated by the Seller and notified to the Purchaser at least three (3) Business Days prior to the Cash Closing (the “Seller’s Bank Account”) and (ii) deliver the Purchaser’s Certificate dated as of the Cash Closing Date to the Seller.

2.3

Share Closing.

(a) The consummation of the sale and purchase of the Exchanged Shares pursuant to the terms of this Agreement (the “Share Closing”) may, in each case subject to the satisfaction or waiver of all conditions set forth in Article VI below as of the Share Closing Date, take place, at the Purchaser’s sole discretion (provided, however, that the Purchaser shall be obligated to provide, at least five (5) Business Days in advance of the Share Closing Date, a written notice to the Seller setting forth the contemplated Share Closing Date), at the Zurich offices of Homburger either (i) on the Cash Closing Date or (ii) at any time during the period starting as of the Cash Closing Date and ending on the fifth (5^th) Business Day after the date of the Purchaser’s annual general shareholders’ meeting approving its financial statements for the fiscal year 2006 (the “Purchaser’s AGM”). The date on which the Share Closing occurs is called the “Share Closing Date”.

(b) At the Share Closing, the Seller shall deliver, or cause to be delivered, to the Purchaser (i) a valid assignment of the Exchanged Shares in writing with written notice to the Company to that effect (provided, however, that the time of delivery of such notice to the Company shall have to be agreed by the Purchaser) and evidence of a book transfer of the Exchanged Shares to the account of the Purchaser through SIS and (ii) a Seller’s Certificate dated as of the Share Closing Date, and shall do all such other acts as may be required under Applicable Law and the articles of incorporation of the Company to transfer the Exchanged Shares and all rights connected therewith to the Purchaser.

(c) At the Share Closing, subject to the approval of its extraordinary shareholders’ meeting, the Purchaser shall (i) deliver the Share Consideration issued to and registered in the name of the Seller by crediting the Seller’s share account in the Purchaser’s register of shareholders with the Share Consideration together with a written confirmation to the Seller from the Purchaser of such entry and (ii) deliver the Purchaser’s Certificate dated as of the Share Closing Date to the Seller.

(d) It is hereby expressly agreed that, at any time during the period starting as of the Cash Closing Date and ending on the fifth (5^th) Business Day after the date of the Purchaser’s AGM, the Purchaser shall be entitled, at its sole discretion (provided, however, that the Purchaser shall be obligated to provide, at least five (5) Business Days in advance of the Cash Payment Option Closing Date, (i) a written notice to the Seller setting forth its decision to exercise the Cash Payment Option in whole or in part, (ii) the number of Exchanged Shares to be acquired by the Purchaser as a result of such exercise and (iii) the contemplated Cash Payment Option Closing Date), to acquire all of the Exchanged Shares for an amount equal to CHF 119,280,000 (one hundred nineteen million two hundred eighty thousand Swiss Francs) in cash (the “Cash Amount”) by wire transfer in immediately available funds to the Seller’s Bank Account in lieu of the Share Consideration (the “Cash Payment Option”). Notwithstanding the immediately preceding sentence, the Purchaser may also elect to acquire only part of the Exchanged Shares in the context of the Cash Payment Option; in such event, the Cash Amount shall be reduced and calculated by multiplying the exact number of Exchanged Shares to be effectively acquired by the Purchaser pursuant to the partial exercise of the Cash Payment Option by CHF 21 (twenty one Swiss Francs), it being understood that the Exchanged Shares not to be effectively acquired by the Purchaser pursuant to the partial exercise of the Cash Payment Option (the “Effectively Exchanged Shares”) shall be transferred to the Purchaser in consideration of a Share Consideration reduced in proportion to the ratio of the Effectively Exchanged Shares over the initial amount of Exchanged Shares set forth in Section 2.1 above. The date on which the Cash Payment Option closing occurs is called the “Cash Payment Option Closing Date”. In the event the Cash Payment Option is exercised by the Purchaser, subject to the satisfaction or waiver of all conditions set forth in Article VI below as of the Cash Payment Option Closing Date, the closing mechanics and deliveries shall be identical in all material respects to those set forth in Sections 2.2(b) and 2.2(c) (the “Cash Payment Option Closing”).

(e) In the event the issuance of the Share Consideration has not been approved or authorized by an extraordinary shareholders’ meeting of the Purchaser at the latest on the date of the Purchaser’s AGM in accordance with Applicable Law and the Cash Payment Option has not been exercised in full by the Purchaser as of such date, the Share Closing shall take place at the latest on the fifth (5^th) Business Day following the date of the Purchaser’s AGM pursuant to the relevant terms and conditions set forth in this Agreement (including the satisfaction or waiver of all conditions set forth in Article VI below as of the Share Closing Date), and the Purchaser agrees to pay to the Seller, as consideration for the Exchanged Shares, an amount equal to the Cash Amount by wire transfer in immediately available funds to the Seller’s Bank Account in lieu of the Share Consideration (provided, however, that in the event of a partial exercise of the Cash Payment Option by the Purchaser prior to the fifth (5^th) Business Day following the date of the

Purchaser’s AGM, the Cash Amount shall be reduced and calculated by multiplying the exact number of Exchanged Shares to be effectively acquired by the Purchaser pursuant to this paragraph (e) by CHF 21 (twenty one Swiss Francs)).

(f) In the event of total or partial exercise of the Cash Payment Option and the Cash Payment Option Closing takes place after the Cash Closing, as the case may be, the Purchaser shall pay to the Seller the Interest by wire transfer in immediately available funds to the Seller’s Bank Account. For the avoidance of doubt, the payment of the Interest shall be made as a single wire transfer on (i) the Cash Payment Option Closing Date in the event the Cash Payment Option is exercised in full by the Purchaser or (ii) on the Share Closing Date and/or the Cash Payment Option Closing Date, whichever occurs later, in the event the Cash Payment Option is exercised in part by the Purchaser.

If any Governmental Authority requires that a hearing be held in connection with any such Mandatory Approval and Notification, each Party shall use its best efforts to arrange for such hearing to be held promptly after the notice that such hearing is required has been received by such Party.

5.4

Compliance with Applicable Laws.

(a) The Seller shall comply in a timely manner and in all respects with all Applicable Laws in connection with or related or arising as a result of (i) the Seller’s ownership of the Owned Shares and (ii) the Seller being a Party to this Agreement, including all Applicable Laws with respect to insider trading and market manipulation.

(b) The Purchaser shall comply in a timely manner and in all respects with all Applicable Laws in connection with or related or arising as a result of the Purchaser being a Party to this Agreement, including all Applicable Laws with respect to insider trading and market manipulation.

5.5 No Transfer of the Owned Shares. The Seller hereby agrees that, at all times during the period commencing with the execution of this Agreement until the Share Closing or the Cash Payment Option Closing (whichever occurs later) or termination of this Agreement in accordance with its terms, the Seller shall not cause or permit any Transfer of any of the Owned Shares (other than for, and solely for, purposes of Article II hereof, subject always to compliance with the provisions of Section 5.4(a) above), or in any way whatsoever discuss, negotiate or make any offer regarding any Transfer of any of the Owned Shares without the prior written consent of the Purchaser. The Seller hereby agrees that, at all times commencing with the

execution of this Agreement until the Share Closing or the Cash Payment Option Closing (whichever occurs later) or termination of this Agreement in accordance with its terms, the Seller shall not deposit, or permit the deposit of, any Owned Share in a voting trust, grant any proxy in respect of the Owned Shares, or enter into any voting agreement or similar arrangement or commitment with respect to any of the Owned Shares.

5.6 Share Consideration Price Adjustment. In the event the Share Consideration (or a part thereof in case of partial exercise of the Cash Payment Option pursuant to Section 2.3(d) above) is transferred to the Seller after the distribution of the Purchaser’s 2006 dividend, the Purchaser shall pay to the Seller, as purchase price adjustment and in cash by wire transfer in immediately available funds to the Seller’s Bank Account, an aggregate amount equal to the paid 2006 dividend per Purchaser Share multiplied by the amount of Purchaser Shares effectively included in the Share Consideration.

5.7 Aggregate Consideration Adjustment. The Aggregate Consideration shall be adjusted for any dilutive effects in respect of the Owned Shares occurring until the Share Closing or the Cash Payment Option Closing (whichever occurs later), as applicable, including dividend payments and other distributions of any kind, demergers, capital increases with an issuance price per Company Share below the then prevailing stock market price, the sale of treasury shares by the Company with a sales price below and the purchase of treasury shares by the Company with a purchase price above the then prevailing stock market price (but excluding capital increases and the sale of treasury shares following the exercise of options that have been issued in the ordinary course of business substantially consistent with prior practice based on the existing employee stock option and share participation plans), the issuance of options, warrants, convertible securities and other rights of any kind to acquire Company Shares, as the case may be, and repayments of capital. In case of dividend payments of any kind, the adjustment shall be effected by deduction of the gross amount of such dividend per Company Share from the Aggregate Consideration, it being understood that such deduction between the Aggregate Cash Amount and the Share Consideration shall be jointly agreed upon between the Parties; in the event the Parties do not agree upon a joint allocation, the allocation of such deduction between the Aggregate Cash Amount and the Share Consideration shall be carried out on a pro-rated basis (it being understood that for such purposes the value of each Purchaser Share shall be CHF 34,02 (thirty four Swiss Francs and two cents)).

In lieu of an adjustment pursuant to the immediately preceding paragraph of this Section 5.7, the Purchaser may require the Seller, at its sole discretion, to transfer to the Purchaser the compensation, right or contribution granted to the Company’s shareholders causing the dilutive effect, including dividends or other distributions, or shares of a demerged part of the Company. Such transfer shall be without additional consideration of any nature (other than reimbursement by the Purchaser of the price paid and the expenses incurred by the Seller in order to obtain such compensation or contribution). If the Company grants to the Seller, or offers to the Seller, or if the Seller has pre-emptive rights for, shares or other equity or equity-linked securities of the Company, including shareholder options, the Seller shall without delay inform the Purchaser and the Purchaser may, in lieu of an adjustment pursuant to the preceding

paragraph, request in writing that the Seller, for the benefit of the Purchaser, acquire and exercise such pre-emptive rights, shares or other equity or other equity-linked securities, including shareholder options, if the Purchaser pre-pays the acquisition and/or exercise price and any related expenses. The transfer to the Purchaser of the securities so acquired by the Seller shall occur at the Cash Closing or, subject to the conditions to closing being satisfied, at a later closing or any other date jointly agreed between the Parties. If such conditions are not satisfied, so that the transactions contemplated in this paragraph do not close, the Seller shall, upon written instruction by the Purchaser, sell the securities so acquired and deliver the net proceeds to the Purchaser.

5.8 Execution of Contribution Agreement. Immediately after the execution of this Agreement, in order to comply with applicable French law provisions relating to contribution (apport en nature) procedures and governing the issuance of the Share Consideration, each of the Parties agrees to execute the contribution agreement (traité d’apport) in the form set forth in Exhibit 1 hereof.

This Agreement and the Exhibits and Schedules hereto constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, between the Parties with respect to the subject matter hereof and thereof.
