to the other Party under this Agreement. Each Party shall have the right, at such Party's expense, through a certified public accountant or like person reasonably acceptable to the other
Party, upon execution of a reasonable confidentiality agreement, to examine such records during regular business hours upon reasonable notice during the life of this Agreement and for 1 calendar year
after its termination; provided, however, that (i) such examination shall not take place more often than once a Contract Year and shall not cover such records for more than the preceding
Contract Year, and (ii) such accountant shall report to such Party only as to the accuracy of the reports or payments provided or made by the other Party under this Agreement. Any adjustments

overpayments or underpayments under this Agreement, shall be made by subtracting or adding, as appropriate, amounts from or to the next payment required to be made to the other Party under this
Agreement, or in the event that no further payments are required to the other Party under this Agreement, within ten (10) days following such identification of overpayments or underpayments.
The Party requesting the audit shall bear the full cost of the audit unless such audit correctly discloses that the discrepancy for the Contract Year differs by more than
[**] percent ([**]%) from the amount the accountant determines is correct, in such case the owing Party shall pay the reasonable fees and
expenses charged by the accountant. In the event that a Party disputes an invoice or other payment obligation under this Agreement, such Party shall timely pay the undisputed amount of the invoice or
other payment obligation, and the Parties shall resolve such dispute in accordance with Article 15.

the subject matter covered by this Agreement. Confidential Information as defined herein shall, without limitation, be deemed to include all notes, analyses, compilations, studies, interpretations or
other documents, whether in tangible form or on electronic or other data storage media, prepared by the receiving Party and its Representatives as defined hereinafter, which contain, reflect or are
based on, in whole or in part, Confidential Information furnished to the receiving Party or its Representatives by the disclosing Party or its Representatives hereunder. Results pertaining to the

12.2Duties of Confidentiality and Non-Use.During the Term, and for a
period of [**] thereafter, each Party hereto will maintain in confidence all Confidential Information disclosed to it as a "receiving" Party by the other Party as a

14

---



or
grant use of such other Party's Confidential Information except as permitted under this Agreement. To the extent that disclosure is authorized by this Agreement, the receiving Party shall obtain
prior written agreement from its employees, agents, consultants, Affiliates, subcontractors and sublicensees (collectively, the "Representatives") to whom disclosure is to be made to hold in
confidence and not make use of such information for any purpose other than those permitted by this Agreement, unless such Representatives are already bound by law or contract to obligations of
confidentiality and non-use no less stringent than those assumed by the receiving Party hereunder. Each receiving Party shall use at least the same standard of care as it uses to protect
its own Confidential Information to ensure that such Representatives do not disclose or make any unauthorized use of such Confidential Information of the disclosing Party. Each receiving Party shall
promptly notify the other disclosing Party upon discovery of any unauthorized use or disclosure of Confidential Information by the receiving Party or any of its Representatives. Confidential
Information shall not include any information which:



12.3Compulsory Disclosure.If a receiving Party or any of a receiving Party's
Representatives are requested or become legally compelled (by oral questions, interrogatories, requests for information or documents, subpoena, civil or criminal investigative demand, or similar
process) or is required by a regulatory body to make any disclosure that is prohibited or otherwise constrained pursuant to this Article 12, the receiving Party will, and will cause such of its
Representatives to, as the case may be, provide the disclosing Party with prompt written notice of such request so that the disclosing Party may seek an appropriate protective order or other
appropriate remedy. Subject to the foregoing, the receiving Party may, and may cause such Representatives to, furnish that portion (and only that portion) of the Confidential Information that, in the
written opinion of its counsel reasonably acceptable to the disclosing Party, the receiving Party is legally compelled or is otherwise required to disclose or else stand liable for contempt or suffer
other material censure or material penalty; provided, however, that the receiving Party must, and must cause its Representatives to, use reasonable efforts to obtain reliable assurance that
confidential treatment will be accorded any Confidential Information so disclosed.

whether required by law or otherwise, it shall give the other Party reasonable notice of the text of the announcement so that the other Party shall have an opportunity to comment upon the
announcement. To the extent that the receiving Party reasonably requests the deletion of any information in any such announcement, the disclosing Party shall delete such information unless, in the
opinion of the disclosing Party's legal counsel, such information is required by law or the rules of any relevant stock exchange to be disclosed. The timing and content of the initial press release
relating to this Agreement, including its existence, the subject matter to which it relates and the transactions contemplated herein will, except as otherwise required by law or any stock exchange
rules, be determined jointly by the Parties.
