b) With regard to ENS, when calculating the Adjusted Gross Sales, the amount of such sales in foreign currencies shall at first be converted in accordance with then current standard practices in the respective company.

9.2. Blocked Countries. If by reason of law a Party (“Paying Party”) is unable to convert to U.S. Dollars a portion of the amount due by it under this Agreement, then such Party shall notify the other Party in writing and the other Party shall have the right to receive such portion. Upon written request from the other Party, the Paying Party shall pay to the other Party such portion, in the currency of any other country designated by the other Party and legally available to the Paying Party.

9.3. Royalty Reports. Each royalty payment shall be accompanied by a report summarizing for each Product the total Adjusted Gross Sales and Net Sales achieved during the relevant six-month period, the currency conversion rates, if applicable, which royalty calculation is being applied, the total royalty payments due and the taxes withheld in accordance with Section 9.4. below, if any.

9.4. Withholding Taxes. If provision is made in law or regulation of any country for withholding of taxes of any type, levies or other charges with respect to any royalty payable under this Agreement, the party required to do so shall promptly pay such

*Portions of this document marked with **** have been omitted pursuant to a request for confidential treatment submitted with the SEC.

18.

tax, levy or charge for and on behalf of the other party to the proper governmental authority. The paying party shall be entitled to deduct any such tax, levy or charge actually paid from royalty due or, if no further payments are due, be promptly reimbursed by the other party, provided however that each party agrees to assist the other party, as may reasonably be necessary, in claiming exemption from such deductions or withholdings under double taxation or similar agreement or treaty from time to time in force and in minimizing the amount required to be so withheld or deducted, and provided further that the paying party shall provide such additional documentation from time to time as is needed for the other party to confirm the payment of tax.

9.5. Audit and Inspection. Either party and its Affiliates, sub-licensees and marketing partner, if any, shall keep, full, true and accurate books of account containing all particulars that may be necessary for the purpose of verifying Net Sales and Adjusted Gross Sales and calculating all royalties payable to the other party. Such books of accounts shall be kept at their principal place of business. Each party or its authorized independent public accountant has the right to engage, at its own expense, an independent public accountant of international reputation to perform, on behalf of the requesting party or its independent public accountant, an audit, conducted in accordance with international accounting and auditing standards (IAAS), of such books and records of the other party and its Affiliates, sub-licensees and marketing partners, if any, that are deemed necessary by the other party to report on Net Sales of Product for the period or periods requested by the requesting party and the correctness of any report or payments made under this Agreement. Upon timely request and at least thirty (30) days’ prior written notice from the requesting party, such audit shall be conducted as an additional audit work during the other party’s annual audit of the countries specifically requested by the requesting party, during regular business hours in such a manner as to not unnecessarily interfere with the other party’s normal business activities, and shall be limited to results in the two (2) full calendar years prior to audit notification. Such audit shall not be performed more frequently than once per calendar year nor more frequently than once with respect to records covering any specific period of time. All information, data, documents and abstracts herein referred to shall be used only for the purpose of verifying royalty statements or compliance with this Agreement, shall be treated as ENS and ROCHE Confidential Information. Audit results shall be shared by and be binding upon the parties. If the audit reveals an overpayment, one party shall promptly reimburse the other party for the amount of

*Portions of this document marked with **** have been omitted pursuant to a request for confidential treatment submitted with the SEC.

19.

the overpayment. If the audit reveals an underpayment, the parties shall promptly make up such underpayment. If the audit reveals that the royalties owed by one party for the countries specifically requested and for any calendar year in total have been understated by more than 10% (ten), the other party shall, in addition, pay the reasonable costs of such additional audit work. The failure of one party to request verification of any royalty calculation within the period during which corresponding records must be maintained will be deemed to be acceptance of the royalty reporting.

9.6. Audit of ENS Development Costs. During the Term of this Agreement, ROCHE has the right to appoint an independent external accountant who audits the Development Costs incurred by ENS by reasonable (i) regular, but not to be conducted more than once a year, or (ii) for cause audits at ENS offices during normal business hours. ENS`s personnel will be informed about the audit process reasonably in advance. Adequate time will be given for the preparation, conduct and evaluation of the audit process essential to gain reliable results.

10.1.1. As to the inventions made solely by person(s) under the control of ENS in the Field, ENS shall have all of the rights it is entitled to receive from such employee(s) or person(s) and shall become automatically ENS Patent Rights,;

10.1.2. As to any inventions made solely by person(s) under control of ROCHE in the Field, ROCHE shall have all of the rights they are entitled to receive from such person(s) and shall become automatically ROCHE Patent Rights;
