(a) to LuxCo I for the LuxCo I Acquired Scient’x Shares shall be a number of shares of Issuer Common Stock (the “ LuxCo I Shares ”) equal to the product obtained by multiplying the Exchange Ratio by the number of LuxCo I Acquired Scient’x Shares (subject to Section 10.3(b) below); and

(b) to LuxCo II for the Acquired Groupe Shares shall be a number of shares of Issuer Common Stock (the “ LuxCo II Shares ”, and together with the LuxCo I Shares, the “ Shares ”) equal to the product obtained by multiplying the Exchange Ratio by the number of Groupe Acquired Scient’x Shares (subject to Section 10.3(b) below).

Once the Issuer Stockholders’ Meeting has been called and noticed, Issuer shall not postpone or adjourn the Issuer Stockholders’ Meeting without the consent of HPC, which consent shall not be unreasonably withheld or delayed, other than (i) for the absence of a quorum or (ii) to allow reasonable additional time for the filing and mailing of any supplemental or amended disclosure that it believes in good faith is necessary under applicable Law and for such supplemental and amended disclosure to be disseminated and reviewed by Issuer’s stockholders prior to the Issuer Stockholders’ Meeting and for the satisfaction of the proviso to the fourth sentence of this paragraph; provided that in the event that the Issuer Stockholders’ Meeting is delayed to a date after the End Date as a result of either (i) or (ii) above, then the End Date shall be extended to the fifth business day after such date). Except as expressly permitted by this Section 8.6, (i) the Issuer Special Committee shall recommend approval of the Issuer Voting Proposal by the stockholders of Issuer and include such recommendation in the Proxy Statement, (ii) none of the Issuer Special Committee, the Issuer Board or any other committee of the Issuer Board shall withdraw, qualify or modify, or publicly propose to withdraw, qualify or modify in any manner adverse to the Sellers or HPC, the recommendation of the Issuer Special Committee that the Issuer’s stockholders vote in favor of the Issuer Voting Proposal (any of the foregoing, or a failure by the Issuer Board or the Special Committee to recommend approval of the Issuer Voting Proposal in the Proxy Statement, an “ Adverse Recommendation Change ”) and (iii) Issuer shall use commercially reasonable efforts to solicit from its stockholders proxies in favor of the Issuer Voting Proposal and subject to the fiduciary duties of the directors, shall take all reasonably necessary action to secure the vote of stockholders required by applicable Law. Notwithstanding the foregoing, at any time prior to the Specified Time, the Issuer Board or the Issuer Special Committee may make an Adverse Recommendation Change if the Issuer Board or the Issuer Special Committee determines in good faith, after consultation with its financial advisor and outside legal counsel, that the failure to do so would reasonably be expected to result in a breach of its fiduciary duties under applicable Law; provided, further , that, in addition to the condition in the immediately preceding clause, the following

61

additional conditions must first be satisfied prior to effecting an Adverse Recommendation Change in response to a Superior Proposal: the Issuer has (A) provided to the Sellers and HPC three Business Days’ prior written notice which notice shall (1) state that it has received a Superior Proposal and describe the material terms and conditions of the Superior Proposal and the identity of the Person or group making the Superior Proposal, (2) include a copy of the current draft of each negotiated agreement comprising the Superior Proposal, and (3) state that the Issuer Board or Issuer Special Committee intends to effect an Adverse Recommendation Change due to the existence of such Superior Proposal; (B) provided to the Sellers and HPC a copy of all written due diligence materials made available to the Person making the Superior Proposal in connection with such Superior Proposal to the extent that such materials have not previously been provided to the Sellers and HPC; (C) during such three Business Days period, if requested by the Sellers or HPC, engaged in, and caused its financial advisors to have engaged in, good faith negotiations with respect to any counterproposal to a Superior Proposal or any amendments to this Agreement; and (D) the Sellers and HPC shall not have, during such three Business Days period, made, and not withdrawn, a bona fide written offer (that will be binding on the Sellers and HPC assuming due authorization and execution thereof by the Issuer) that the Issuer Board or the Issuer Special Committee has in good faith determined results in the Superior Proposal no longer being a Superior Proposal. Nothing contained in this Section 8.6 or otherwise contained in this Agreement shall be deemed to prohibit Issuer from taking and disclosing to its stockholders a position with respect to a tender offer required by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act or from making any required disclosure to Issuer’s stockholders if, in the good faith judgment of the Issuer Special Committee or the Issuer Board after consultation with outside legal counsel, failure to so disclose would conflict with applicable Law; provided, however, that except as specifically permitted in this Section 8.6, neither the Issuer, the Issuer Board nor the Issuer Special Committee shall withdraw or modify its recommendation to approve the Issuer Voting Proposal, or propose to any person outside the Issuer to approve or recommend an Issuer Acquisition Proposal.

The Minority Purchase Agreements shall be substantially in the form set forth as Exhibit C attached hereto. In the event that any Minority Scient’x Shareholder has not executed and delivered a Minority Purchase Agreement within a reasonable time after the date hereof, the Sellers and HPC will consult with Issuer and the Special Committee with regard to next steps to be taken with a goal to acquisition of any such Scient’x Shares not yet committed to be sold to Issuer.

70

11.3 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 full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

11.4 Entire Agreement .

11.7 Failure or Indulgence Not Waiver; Remedies Cumulative; Waivers . No failure or delay on the part of any Party in the exercise of any right hereunder will impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor will any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. All rights and remedies existing under this Agreement are cumulative to, and not exclusive to, and not exclusive of, any rights or remedies otherwise available. To the maximum extent permitted by Law, (i) no waiver that may be given by a party will be applicable except in the specific instance for which it is given; and (ii) no notice to or demand on one party will be deemed to be a waiver of any obligation of that party or of the right of the party giving such notice or demand to take further action without notice or demand as provided in this Agreement or the documents referred to in this Agreement. Any agreement on the part of a party to this Agreement to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of

11.9 Governing Law . This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware applicable to contracts executed in and to be performed in that jurisdiction excluding (to the greatest extent a Delaware court would permit) any rule of Law that would cause the application of the Laws of any jurisdiction other than the State of Delaware.

11.10 Enforcement . Except as otherwise expressly provided herein, any and all remedies herein expressly conferred upon a party hereunder shall be deemed cumulative with and not exclusive of any other remedy conferred hereby or by Law on such party, and the exercise of any one remedy shall not preclude the exercise of any other. The parties acknowledge and agree that each other party hereunder would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms and that any breach of this Agreement by a party hereunder could not be adequately compensated in all cases by monetary damages alone. Accordingly, in addition to any other right or remedy to which a party hereunder may be entitled, at Law or in equity, it shall be entitled to enforce any provision of this Agreement by a decree of specific performance and temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Agreement, without posting any bond or other undertaking.

Each of the parties hereto agrees that a final judgment in any such action or proceeding may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Nothing in this Agreement shall affect the right of any party to this Agreement to serve process in any other manner permitted by Law.

No failure or delay on the part of any Party in the exercise of any right hereunder will impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor will any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. All rights and remedies existing under this Agreement are cumulative to, and not exclusive to, and not exclusive of, any rights or remedies otherwise available.

The parties acknowledge and agree that each other party hereunder would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms and that any breach of this Agreement by a party hereunder could not be adequately compensated in all cases by monetary damages alone. Accordingly, in addition to any other right or remedy to which a party hereunder may be entitled, at Law or in equity, it shall be entitled to enforce any provision of this Agreement by a decree of specific performance and temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Agreement, without posting any bond or other undertaking.
