Any breach which may only be remedied by way of cash payment shall be remedied by Sellers by way of cash payment to the Companies or, at the choice of Purchaser, to Purchaser. Any breach which may either be remedied by way of cash payment or by way of restitution in kind (Naturalrestitution) shall, at the choice of Sellers, be remedied in either way. Sellers shall inform Purchaser without undue delay after having been notified of such breach by Purchaser in accordance with section 7.11 (a) whether Sellers intend to remedy the breach by way of cash payment or by restitution in kind. If ▇▇▇▇▇▇▇ choose to remedy the breach by way of restitution in kind and the breach is not remedied within a reasonable time not exceeding 60 days after Sellers have been notified of such breach according to Section 7.11 (a), Sellers shall remedy the breach by way of cash payment to the Companies or, at the choice of Purchaser, to Purchaser.

Any Losses incurred including Losses in a Company not 100 % owned (directly or indirectly) by the Sellers at the date hereof shall be taken into account only on a pro rata basis in proportion to the respective direct or indirect shareholding of Sellers at the date hereof (durchgerechnete Beteiligung).

(b)

Sellers shall only be liable under this Agreement for any Loss to the extent that such Loss is not attributable (i) to a failure by Purchaser to mitigate the Loss or a failure by Purchaser which caused (verursacht oder mitverursacht) the Loss (Section 254 of the German Civil Code) or (ii) to a non-compliance by Purchaser with the procedures set forth in Section 7.11 below.

7.6

7.8

Limitation Periods

Irrespective of Purchaser’s or Parent’s knowledge of the underlying facts and/or claims according to Section 7.5 , but except in case of fraud or intentional misrepresentation by Sellers, all claims of Purchaser under any representation of Sellers or any covenant in Section 6.1 shall be time-barred (verjähren) upon expiration of a period of [ *** ] after the Closing Date, except for claims under the representations of Sellers contained in Section 4.2 (a) to (d) (in particular

***CONFIDENTIAL TREATMENT REQUESTED

ownership of Sold Shares; absence of third-party rights on Sold Shares), which shall be time-barred [ *** ] after the Closing Date. Unless expressly provided otherwise in this Agreement, all other rights and remedies of Purchaser under this Agreement shall be time-barred upon the expiration of a period of [ *** ] after the date hereof except in case of fraud or intentional misrepresentation by Sellers. Claims pursuant to Section 9 shall be time barred in accordance with Section 9.7. For the avoidance of doubt, the knowledge of Sellers of facts or circumstances which may lead to a Purchaser Claim under Section 8 is not deemed to be a case of intentional misrepresentation in the meaning of this Section.

(b)

Any limitation period pursuant to this Agreement shall be extended (gehemmt) only in the event that a statement of claim is filed with the competent arbitral court (in accordance with Section 11.5 (b)) within the applicable limitation period (Section 204 (1) No. 1 of the German Civil Code).

Indemnification Procedures

(a)

In the event of a breach of a representation, covenant or agreement of Sellers contained in this Agreement, Purchaser shall without undue delay, however in any case not later than 20 Business Days following the discovery of such breach, notify Sellers of any breach in writing, describe its claim in detail, and to the extent then feasible, set forth the estimated amount

***CONFIDENTIAL TREATMENT REQUESTED

of such claim. However, for the avoidance of doubt, the failure of Purchaser to give such notice shall relief Sellers of their obligations to indemnify Purchaser according to this Section 7 only if and to the extent that the non-compliance of Purchaser with its obligation to give such notice increases any Loss resulting out of such breach (Section 7.1 (b)), whereas Sellers shall bear the burden of proof that the Loss is increased by such non-compliance of Purchaser. Without prejudice to the validity of the Purchaser Claim in question, Purchaser shall allow, and shall cause the Companies to allow, Sellers and their accountants and their professional advisors to investigate the matter or circumstance alleged to give rise to such Purchaser Claim, and whether and to what extent any amount is payable in respect of such Purchaser Claim and, for such purpose, Purchaser shall give and shall cause the Companies to give, subject to their being paid their reasonable out-of-pocket costs and expenses as well as reasonable advisor fees, expenses and disbursements, such information and assistance, including access to the Companies’ premises and personnel during normal business hours and to an extent not unreasonably preventing the personnel of the Companies to fulfill their regular tasks as employees of the Companies in which case the access rights to the Companies’ personnel may be immediately revoked by Purchaser, and including the right to examine and copy or photograph any assets, accounts, documents and records, as Sellers or their accountants or professional advisors may reasonably request.

(b)

In the event that any action, claim, demand or proceeding with respect to which Sellers may be liable under this Agreement (the “Third Party Claim”) is asserted or announced in writing by any third party (including any governmental authority) against Purchaser or any Company (the “Claim Addressee”), Sellers shall receive written notice of such Third Party Claim without undue delay, however in any case not later than 10 Business Days following the receipt of the Third Party Claim by Purchaser or any Company, and defend the Claim Addressee against such Third Party Claim upon written request of Purchaser. However, for the avoidance of doubt, the failure of Purchaser or any Company to give such notice shall relief Sellers of their obligations to indemnify Purchaser according to this Section 7 only if and to the extent that the non-compliance of Purchaser or any Company with its obligation to give such notice increases any Loss resulting out of such Third Party Claim (Section 7.1 (b)), whereas Sellers shall bear the burden of proof that the Loss is increased by such non-compliance of Purchaser. In such case, Sellers shall have the right to defend the Claim Addressee by all appropriate actions

and have the power to direct and control such defense. In particular, ▇▇▇▇▇▇▇ may participate in and direct all negotiations and correspondence with the third party, appoint and instruct counsel and request that the Third Party Claim be litigated or settled in accordance with ▇▇▇▇▇▇’s instructions upon prior written consent of Purchaser which shall not be unreasonably withheld. In case the defense against the Third Party Claim is lead by Purchaser or any Company, the Third Party Claim may only be litigated or settled in accordance with Purchaser’s or the Company’s instructions upon prior written consent of Sellers which shall not be unreasonably withheld. The Parties shall conduct the proceedings in good faith using reasonable endeavors to take the Claim Addressee’s interest into account. Sellers or Purchaser, respectively, shall in particular keep Purchaser or Sellers, respectively, informed about the status of the proceedings. Sellers may authorize one or two among them to defend the Claim Addressee against the Third Party Claim. To the extent that Sellers are in breach of a representation, covenant or agreement, all costs and expenses incurred by Sellers or reasonably incurred by Purchaser or any Company (including advisors’ fees) in defending the Third Party Claim shall be borne by Sellers. If it turns out that Sellers were not in breach, any costs and expenses reasonably incurred by them, the Purchaser or the Companies in connection with the defense (including advisors’ fees) shall be borne by Purchaser.

(c)

If and to the extent Sellers defend a Claim Addressee against a Third Party Claim, Purchaser shall cause each Claim Addressee (i) to fully cooperate with Sellers in the defense of any Third Party Claim, (ii) to diligently conduct themselves in order to keep the Loss as low as possible, (iii) to provide Sellers’ representatives access, upon reasonable advance notice and during normal business hours, to all relevant books and records, other information, premises and personnel of the Companies and to an extent not unreasonably preventing the personnel of the Companies to fulfill their regular tasks as employees of the Companies in which case the access rights to the personnel may be revoked by Purchaser immediately, (iv) to allow Sellers and their representatives to copy or photograph any assets, accounts, documents and records for the purpose of avoiding, disputing, defending, appealing, compromising or contesting any Third Party Claim or liability as Sellers or their advisors may reasonably request, (v) to deliver to Sellers copies of all relevant orders (Bescheide), decisions, filings, motions and other documents of any court, authority or party to the conflict, and (vi) to give Sellers reasonable opportunity to comment on and discuss with Purchaser and Companies any measures which Sellers believe are necessary or appropriate to take or to omit in connection with a Third Party Claim (without any obligation on the part of

Purchaser to take such action and without limiting Sellers’ obligations under Section 7.1), and to comment on and review any reports and documents and to participate in all relevant tax and social security audits, court hearings and any other meetings. If and to the extent Purchaser or any Company defend against the Third Party Claim, Purchaser and/or the Company shall reasonably cooperate with Sellers in the defense of the Third Party Claim, diligently conduct themselves in order to keep the Loss as low as possible and keep Sellers informed about the status of the proceedings. Any costs and expenses reasonably incurred by Purchaser or any Company in connection with the cooperation or defense in accordance with this Section 7.11 (c) (including advisors’ fees) shall be borne by Purchaser except if and to the extent Sellers were in breach of any representation, agreement or covenant in which case Sellers shall bear such costs and expenses. If it turns out that Sellers were not in breach, any costs and expenses reasonably incurred by them, the Purchaser or the Companies in connection with the defense (including advisors’ fees) shall be borne by Purchaser.

7.12

No additional Rights or Remedies

(a)

The Parties agree that the rights and remedies which Purchaser and Sellers may have with respect to the breach of a representation, warranty, covenant or agreement or with respect to an indemnity contained in this Agreement are limited to the rights and remedies explicitly contained herein.

(ii) and 2.4 (b) with respect to the representations given by ▇▇▇▇▇▇▇▇▇ and Parent under Sections 5.1 (d) and 5.4 (b)-(d).

Such cooperation shall include, without limitation, providing or making available by Sellers, Purchaser and the Companies all relevant books, records and documentation and the reasonable assistance of officers and employees during normal business hours. ▇▇▇▇▇▇▇▇▇ agrees to retain all books, records and documentation relating to the Companies that may be relevant in connection with any audit or investigation for which Sellers may be responsible hereunder until the expiration of any applicable statute of limitation. Sellers shall bear the costs of such cooperation, in particular any reasonable advisors fees, but excluding overhead costs of the Companies.

9.6

Tax Audits and Contests

(a)

Purchaser shall keep Sellers fully informed regarding the commencement of any audit or other proceeding which may give rise to a claim under Section 9.1 above. In particular, Sellers shall be notified by Purchaser of any Tax audit relating to time periods ending on or before the Closing Date without undue delay, however, in any case no later than 10 Business Days after receipt of the relevant information from the Tax authority, but at least 10 Business Days prior to the beginning of such tax audit, after Purchaser or the relevant Company has received the relevant information from the Tax authority, and Purchaser shall, and shall procure that the Companies will, forward to Sellers copies of any correspondence of and with the Tax authorities regarding a Tax against which the Sellers may be obliged to indemnify the Purchaser. Each notification shall be in writing. However, for the avoidance of doubt, the failure of Purchaser to give such notices shall relieve Sellers of their obligations to indemnify Purchaser according to this Section 9 only if and to the extent that the non-compliance of Purchaser with its obligation to give such notices increases the amount of the indemnifyable Taxes according to Section 9.1, whereas Sellers shall bear the burden of proof that the amount of the indemnifyable Taxes is increased by such non-compliance of Purchaser.

(b)

Sellers may, upon prior written consent of Purchaser not to be unreasonably withheld, direct, through counsel of their own choice and at their own expense, any reasonable actions including, without limitation, legal remedies to be taken with respect to any audit, claim for refund and administrative or judicial proceeding involving any asserted liability with respect to taxable periods or portions thereof ending on or before the Closing Date, or any refunds, credits or other benefits to which Sellers may be entitled pursuant to this Section 9 (any such audit, claim for refund or proceeding relating to an asserted Tax liability or refund, credit or other benefit is referred to herein as a “Contest”).

(c)

If Sellers direct a Contest, then (i) Purchaser shall cause the Companies to reasonably cooperate with Sellers, (ii) Purchaser shall empower and shall cause the Companies to empower the designated representatives of Sellers to represent the relevant Company in the Contest insofar as the Contest involves an asserted Tax liability relating to taxable periods or portions thereof ending on or before the Closing Date, (iii) Sellers shall conduct the Contest in good faith using reasonable endeavors to take Purchaser’s interest into account and (iv) Sellers shall keep Purchaser informed about the status of the proceedings. However, Purchaser and the Companies may, at their own expense, continue to participate in the Contest but may not assume such Contest from Sellers. Besides, Sellers may not litigate or settle a Contest without the prior written consent of Purchaser not to be unreasonably withheld.

9.7

Limitation

Any claims under this Section 9 shall be time barred (verjähren) upon the earlier of (i) the date falling six (6) months after the day of determination (Festsetzung) of the respective final and non-appealable and unchangeable Tax liability by the relevant Tax authority or (ii) the date falling six (6) months after the end of the regular statutory prescription (Festsetzungsverjährung).

9.8

Application of Section 7

Section 7 shall apply mutatis mutandis.

Section 10

Parent Guarantee

Parent hereby unconditionally and irrevocably guarantees in the form of an independent undertaking (Section 311 German Civil Code) to Sellers the due and punctual performance of all obligations assumed by Purchaser under this Agreement, in particular regarding the payment of the Base Purchase Price, the Additional Purchase Price and of the IMV Loan I-III Purchase Price.

11.2

Public Disclosure; Confidentiality

(a)

The Parties must keep secret the contents of this Agreement to the extent that no statutory disclosure obligations exist or the respective other Party has not consented to the disclosure unless such disclosure serves a valid business purpose of either Party.

(b)

The Parties must also keep secret any information they have received about each other and about the companies affiliated with the respective other Parties as defined in section 15 German Stock Corporation Act (AktG) since they have started discussions about the acquisition of the Sold Shares, to the extent that such information is not known or available to the

public (other than as a result of a breach of this Section 11.2) or the respective other Party has not consented to the disclosure of the information. If any of Sellers is required by virtue of law or based on an contractual obligation to disclose any of the information described above, except for mandatory obligations to disclose such information to the Tax authorities, such Seller(s) shall immediately provide Purchaser with a written notice setting forth the applicable law or contractual provision and the third party requiring such disclosure, if any, in order to enable Purchaser to seek a protective order or other appropriate remedy. Sellers will reasonably cooperate with Purchaser in any attempt by Purchaser to obtain any such protective order or other remedy. If Purchaser is unsuccessful in obtaining any such protective order or other remedy in connection with the requirement of any Seller to disclose such information, and if Seller provides Purchaser with a written opinion of its legal counsel confirming that, and the extent to which a disclosure of such information is legally required, then such Seller may disclose such information, but only to the extent legally required and as advised by its legal counsel. However, such Seller shall use reasonable efforts to ensure that such information is treated confidentially by each person to whom it is disclosed.

(c)

Each of the Parties hereto undertakes that prior to the Closing Date it will not make any announcement in connection with this Agreement unless the other Parties hereto have given their respective prior consent to such announcement, including the form of such announcement, which consent may not be unreasonably withheld and may be subject to conditions. The preceding sentence shall, however, not apply if and to the extent any announcement or disclosure of information regarding the existence, the subject matter or the content of this Agreement is required to be made under applicable laws or applicable stock exchange rules or serves a valid business purpose of either Party.

11.3

Costs and Expenses

(a)

All costs including but not limited to fees, registration duties or other charges in connection with any regulatory requirements and other charges and costs payable in connection with the execution of this Agreement and the implementation of the transactions contemplated hereby shall be equally borne by Sellers and Purchaser. Sellers shall be responsible for their own corporate income tax and trade income tax resulting from the sale of the Sold Shares under this Agreement.

(b)

Each Party and Parent shall pay its own expenses, including the costs of its advisors, incurred in connection with this Agreement. Without limiting the generality of the foregoing, Sellers shall bear and pay all fees, costs and expenses (including all legal fees and expenses payable to counsel for the Companies) that have been incurred by or on behalf of any of the Companies or any of the Sellers, in particular in connection with:

(i)

the negotiation, preparation and review of any term sheet or similar document relating to any of the transactions contemplated by this Agreement;

(ii)

the investigation and review conducted by Purchaser and its representatives with respect to the Companies’ business (and the furnishing of information to the Purchaser and its representatives in connection with such investigation and review) except for overhead costs of the Companies in connection with such investigation and review;

(iii)

the negotiation, preparation and review of this Agreement (including the exhibits and schedules hereto), and all certificates, opinions and other instruments and documents delivered or to be delivered in connection with the transactions contemplated hereby;

(iv)

the preparation and submission of any filing or notice required to be made or given in connection with any of the transactions contemplated by this Agreement, and the obtaining of any consent required to be obtained in connection with any of the transactions contemplated by this Agreement; and

(v)

the consummation and performance of the transactions contemplated by this Agreement.

For the avoidance of doubt, the advisory fees for the services rendered by ▇▇▇▇▇ Partners Management and Technologie Consultants pursuant to the “Beratungsvertrag/Operative Unterstützung” with MC AG dated 20 April 2007 have been incurred by MC AG. These fees were not incurred on behalf or for the benefit of the Sellers but solely for the benefit of the Companies.

No Company shall bear or pay, and Sellers shall not permit any Company to bear or pay, any such fees, costs or expenses.

11.4

Entire Agreement; Amendments and Waivers

(a)

This Agreement (including all Exhibits hereto) contains the entire agreement between the Parties with respect to the subject matter hereof and supersedes all prior agreements and understandings with respect thereto, except for the Confidentiality Agreement dated 7 February 2007, which will remain in full force and effect until the Closing Date (or, with respect to business or trade secrets of Sellers, for the time period stated therein) or, if this Agreement is terminated pursuant to Section 3.2 (e), beyond the date of such termination according to its terms.

(b)

Any provision of this Agreement (including this Section 11.4) may be amended or waived only if such amendment or waiver is by written instrument executed by all Parties and explicitly refers to this Agreement.

11.5

Governing Law; Venue; Service of Process

(a)

This Agreement shall be governed by, and construed in accordance with, the laws of the Federal Republic of Germany (excluding conflict of laws rules).

(b)

Any dispute arising out of or relating to this Agreement, or the breach, termination or validity or invalidity thereof, shall be referred to and finally resolved by arbitration in accordance with the rules of the German Institute of Arbitration e.V. (DIS e.V.) without recourse to the ordinary courts of law. The exclusion of recourse to the ordinary courts of law also comprises the right to third-party notice (Streitverkündung) between the parties of this Agreement in connection with a dispute arising in connection with this Agreement between any party of this Agreement and a third party. The place of arbitration shall be Düsseldorf, Germany, the language of the arbitration shall be English. Documents in another language than English shall be translated into the English language, unless the Parties agree otherwise. The tribunal shall consist of one arbitrator to be jointly nominated by the Parties who needs to be qualified to work as judge in Germany and needs to be in good command of the English language. If the Parties cannot agree on the arbitrator, he shall be nominated by DIS e.V. upon request of either party. If the arbitrator considers necessary, he shall have the right to mandate a third party expert with respect to particular items in dispute between the Parties, in particular in connection with the determination on whether the

underlying conditions to the Additional Purchase Price I and the Additional Purchase Price II have been met. The third party expert shall decide on the items referred to him by the arbitrator with binding effect for the Parties. The right to obtain injunctive relief before state courts shall not be excluded hereby.

(c)

Purchaser and Parent hereby appoint the law firm of Bird & Bird as their agent for service of process (Zustellungsbevollmächtigter) for all legal proceedings involving Purchaser or Parent, respectively arising out of or in connection with this Agreement. This appointment shall only terminate upon the appointment of another agent for service of process domiciled in Germany, provided that the agent for service of process is an attorney admitted to the German bar (in Deutschland zugelassener Rechtsanwalt) and his appointment has been notified to Sellers. Purchaser and Parent shall promptly after the date hereof and upon the appointment of any new agent for service of process (as the case may be) issue to the agent a written power of attorney (Vollmachtsurkunde) and shall irrevocably instruct the agent to submit such deed in connection with any service of process under this Agreement.

11.6

Interpretation

(a)

The headings of the sections and subsections in this Agreement are for convenience purposes only and shall not affect the interpretation of any of the provisions hereof.

(b)

Terms to which a German translation has been added shall be interpreted as having the meaning assigned to them by the German translation.

(c)

Unless otherwise specified herein, all references to money are understood to be in Euro or USD, respectively. All payments shall be payable in USD or EUR, respectively, and will not be subject to any adjustment or exchange pursuant to fluctuations in foreign exchange rates.

(d)

For the purpose of this Agreement, a “Business Day” shall be any day other than a Saturday, Sunday or other day on which banks in Frankfurt am Main, Germany, are generally closed.

11.7

Definitions

Exhibit 11.7 sets forth a – not necessarily comprehensive – list of the capitalized terms used in this Agreement, indicating the sections where such terms are defined. Terms defined in the singular have a comparable meaning when used in the plural, and vice versa.

11.8

Severability

Should any provision of this Agreement, or any provision incorporated into this Agreement be or in the future become invalid or unenforceable, the validity or enforceability of the other provisions of this Agreement shall not be affected thereby. The invalid or unenforceable provision shall be deemed to be substituted by a suitable and equitable provision which, to the extent legally permissible, comes as close as possible to the intent and purpose of the invalid or unenforceable provision. The same shall apply: (i) if the Parties have, unintentionally, failed to address a certain matter in this Agreement (Regelungslücke); in this case a suitable and equitable provision shall be deemed to have been agreed upon which comes as close as possible to what the Parties, in the light of the intent and purpose of this Agreement, would have agreed upon if they had considered the matter; or (ii) if any provision of this Agreement is invalid because of the scope of any time period or performance stipulated herein; in this case a legally permissible time period or performance shall be deemed to have been agreed which comes as close as possible to the stipulated time period or performance.
