a) Payment Term

Payments shall be made by ROCHE on Net Sales of any Product on a country-by-country and Product-by-Product basis during the Payment Term.

The following payment rates shall apply to the respective tiers of aggregate Calendar Year Net Sales of a Product per geographic area of the Territory, on an incremental basis, as follows:

i) For aggregate countries other than Japan

Tier of Calendar Year Net Sales in million US$	Percent (%) of Net Sales

> [***]—[***]	[	***]%
> [***]—[***]	[	***]%
> [***]	[	***]%

Tier of Calendar Year Net Sales in million US$	Percent (%) of Net Sales
< [***]	[	***]%
> [***]—[***]	[	***]%
> [***]—[***]	[	***]%

faith and agree to an appropriate adjustment to Net Sales to reflect the relative pharmaceutical activity of the Product and the other pharmaceutically active agent(s) contained in the Combination Product. If, after such good faith negotiations not to exceed ninety (90) days, the Parties cannot agree to an appropriate adjustment, the dispute shall be initially referred to the executive officers of the Parties in accordance with Section 18.1.2. Should the Parties fail to agree within sixty (60) days of such referral, then the Net Sales shall equal such portion of the Net Sales of the Combination Product which is equivalent to the relative contribution to the pharmaceutical activity of the Product within the Combination Product, as determined by an Expert jointly appointed by the Parties within a further thirty (30) days.

e) Knowledgeable Persons on EVOTEC’s Side

If guarantees set forth in Section 13 refer to the best knowledge of EVOTEC, this means the knowledge of all senior employees (i.e. authorized officer “Prokurist” and higher) of EVOTEC who have been involved in the development of the Compounds and Products and/or the preparation of the transfer of the Assets at any time in the period between the July 31, 2008 and the Closing Date.

f) Overall Scope of EVOTEC’s Liability pursuant to this Agreement

EVOTEC’s aggregate liability pursuant to this Agreement other than its liability pursuant to Section 14.2 shall be limited to US Dollars [***] ($[***]). In the event of willful misconduct, fraudulent concealment or willful deceit, however, EVOTEC’s liability shall not be limited.

g) Limitation

All claims of ROCHE arising in connection with this Agreement other than those arising from EVOTEC’s obligations as stipulated in Section 14.2 (Employees of EVOTEC) shall be time-barred twelve (12) full calendar months from Closing.

h) Sole Remedy

ROCHE agrees that its remedies with respect to any and all damage or loss incurred by it relating to the subject matter of this Agreement shall exclusively be governed by the provisions of this Agreement. To the extent legally permissible, all other statutory or contractual claims or remedies relating to the subject matter of this Agreement other than those on the grounds as stated in Section 14.1 f) second sentence (Overall scope of liability), are expressly excluded, in particular, any claims for reduction of the purchase price or improvement based on faultiness of the object of purchase, recession, challenge, damage claims for breaching an obligation in connection with the preparation or negotiation of this Agreement by the parties or their representatives prior to the conclusion of this Agreement (culpa in contrahendo). The provisions of Section 17 (Transfer of Rights) remain unaffected.

14.2 Indemnification with respect to employees of EVOTEC

a) The Parties jointly assume that the return of Roche’s rights and the sale and transfer of the Assets does not constitute a transfer of undertaking within the meaning of sec. 613a of the German Civil Code (BGB). Accordingly, the Parties further assume that no employees of EVOTEC will transfer across to ROCHE under sec. 613a German Civil Code and that ROCHE will not be obliged to reinstate any former employees of EVOTEC because of the Transaction.

b) If an employee of EVOTEC should claim that his employment with EVOTEC has transferred across to ROCHE under sec. 613a German Civil Code because of the Transaction, then ROCHE shall

(i) immediately inform EVOTEC in writing and

(ii) take all necessary steps to terminate, on a precautionary basis, any possibly existing employment relationship between ROCHE and such employee, including, but not limited to, the issuance of a notice letter and the offering of a termination agreement.

This applies mutatis mutandis where a former employee of EVOTEC should claim to be reinstated by ROCHE in connection with sec. 613a German Civil Code because of the Transaction.

Commission pursuant to the Registrant’s application requesting confidential treatment under Rule 24b-2

of the Securities Exchange Act of 1934.

c) If, contrary to the Parties’ common understanding, a competent court of last instance, or, where EVOTEC agrees with ROCHE in writing not to appeal the decision of a competent inferior court, such inferior court should hold that any employee of EVOTEC has transferred across to ROCHE under sec. 613a German Civil Code because of the Transaction or that, because of the Transaction, then ROCHE is obliged to reinstate any former employee of EVOTEC (hereinafter “Transferring Employee”), EVOTEC shall indemnify ROCHE for

(i) all claims of whatever nature and amount in connection with the employees possibly transferred, including but not limited to base salary, any social security contributions and any fringe benefits (e.g. holiday pay, bonus) the Transferring Employee is entitled to during the period between the Transferring Employee’s transfer to ROCHE and the first possible date of termination of the Transferring Employee’s employment but at least until the date when the termination of such a transferred employment is declared legally valid;

(ii) the cost of a severance payment to the Transferring Employee in consideration for the Transferring Employee accepting the termination of his employment provided that the amount to be paid to the Transferring Employee has been agreed between EVOTEC and ROCHE in writing before the payment is made;

(iii) all reasonable legal advisory fees incurred by ROCHE

(x) in litigation with the Transferring Employee on a transfer of such employee’s employment to ROCHE or an obligation of ROCHE to reinstate such employee or

(y) in connection with the termination of such employee.

The parties agree that EVOTEC shall be entitled to choose the legal advisor to render the aforementioned legal services to ROCHE.

d) EVOTEC shall not be obliged to indemnify ROCHE under Section 14.2 c) if ROCHE effectively employs the Transferring Employee by its own decision prior to or within one year following the Closing Date.

e) The indemnification payment described in Section 14.2. c) shall be payable within one month following the decision of the competent court of last instance or, where EVOTEC agrees with ROCHE in writing not to appeal the decision of a competent inferior court, within one month following the serving of the full judgment of the such court to both Parties upon receipt by EVOTEC of a proper invoice evidencing the payments ROCHE has made to the Transferring Employee.

16.4 Publications

If EVOTEC wishes to publish the results of its development efforts with respect to the Assets which were achieved until the Closing of this Agreement, EVOTEC shall submit to ROCHE a draft of the proposed manuscript for review, comment and consideration at least four (4) weeks prior to any submission for publication or other public disclosure. EVOTEC further agrees, upon written request of ROCHE, not to submit such manuscript for publication for an additional sixty (60) days in order to allow for actions to be taken, which are necessary to preserve rights to patents or to refrain from publication. ROCHE shall have the right to object to such publications of EVOTEC.

16.5 Failure of ROCHE to comply with Covenants under Sections 16.1, 16.2 or 16.3

In the event that EVOTEC asserts that ROCHE has failed to comply with its covenants as stipulated in Sections 16.1, 16.2 or 16.3 above, EVOTEC shall so notify ROCHE in writing and state the grounds for its assertion. Within sixty (60) days of its receipt of such notice, ROCHE shall respond in writing and, if it asserts that it has not failed to comply with its covenants as stipulated in Sections 16.1, 16.2 or 16.3 above, provide EVOTEC with sufficient information to that effect. Unless EVOTEC agrees that ROCHE has not failed to comply with its covenants as stipulated in Sections 16.1, 16.2 or 16.3 above, the matter shall be resolved in accordance with Sections 18.3 and 18.4. In the event that a party takes legal action and the arbitration tribunal holds that ROCHE has failed to comply with its covenants as stipulated in Sections 16.1, 16.2 or 16.3 above, Roche shall have the right to exercise its right to license and transfer the Assets as set forth in Section 17 within ninety (90) days following delivery of the respective final decision of the court of arbitration to ROCHE. In the event that ROCHE fails to do so, EVOTEC shall be entitled to exercise the right in Section 17 on behalf of ROCHE by written notice to ROCHE, and upon delivery of such notice, the license and transfer in Section 17 will take effect immediately. EVOTEC shall be obligated to exercise its right within sixty (60) days from receiving the right to do so pursuant to this Section 16.5. In the event that EVOTEC fails to do so, EVOTEC’s right shall cease. For the avoidance of doubt, with respect to the time prior to the transfer of rights under Section 17, such license and transfer pursuant to Section 17 will not release ROCHE from complying with its covenants as stipulated in Sections 16.2 and 16.3 nor from curing any non-compliance as determined as a result of the processes stipulated in Sections 19.3 and 19.4.
