Notwithstanding the foregoing, each Party may disclose the other Party's Confidential Information only to the extent such disclosure is reasonably necessary in filing or prosecuting Patent Rights, prosecuting or defending litigation, complying with applicable governmental laws or regulations, making a permitted sublicense of its rights hereunder or conducting clinical trials or otherwise in performing its obligations or exercising its rights hereunder, provided that if a Party is required to make any such disclosure of the other Party's Confidential Information, it will, whenever reasonably possible, give advance notice to the latter Party of such disclosure requirement, will cooperate with the other Party in its efforts to secure confidential treatment of such Information prior to its disclosure (whether through protective orders or confidentiality agreements or otherwise), and will use reasonable efforts to limit the extent of such disclosure and, if requested by the other Party because of an inability of such other Party to seek confidential treatment, to secure confidential treatment of such Information prior to its disclosure (whether through protective orders or confidentiality agreements or otherwise). 6.2 PRESS RELEASES. Except to the extent required by law or as otherwise permitted in accordance with this Section 6.2 or Section 6.3, neither Party shall make any public announcements concerning this Agreement or the subject matter hereof without the prior written consent of the other Party, which consent shall not be unreasonably withheld or delayed.

Except as set forth in Section 6.3 hereof, in the event of a required or desired public announcement, such Party shall provide the other Party with a reasonable opportunity and the right to approve the content of such announcement prior to its being made, which approval shall not be unreasonably withheld or delayed. Furthermore, each Party shall give the other Party a reasonable opportunity to review all filings with the United States Securities and Exchange Commission describing the terms of this Agreement prior to submission of such filings, and shall give due consideration to any reasonable comments by the non-filing Party relating to such filing, including without limitation the provisions of this Agreement for which confidential treatment should be sought. 6.3 PUBLICATIONS. Notwithstanding the terms of Section 6.2, either Party may publish Information that such Party discovered or developed in its research, development or commercialization activities derived from use of the Library or any Library Compound without the consent of or notice to the other Party, provided, however, that no such publication may contain any Confidential Information of the other Party, or may disclose the structure of a Library Compound or Information that reasonably may be interpreted to disclose the structure of a Library Compound unless: (a) such structure is in the public domain at the time of such publication; or (b) such structure was independently discovered by employees of the publishing Party who had no access to the Library, the Library Compounds or any Confidential Information of the other Party; or (c) the disclosure of such structure is required to support a patent filing pursuant to Section 5.2; or (d) the other Party has consented in writing to such disclosure. 7.

In no event, however, may the indemnifying Party compromise or settle any claim or suit in a manner which admits fault or negligence on the part of the indemnified Party without the prior written consent of the indemnified Party. The indemnifying Party shall have no liability under this Article 7 with respect to claims or suits settled or compromised without its prior written consent. 8. TERMINATION AND EXPIRATION 8.1 TERM AND TERMINATION. This Agreement shall commence upon the Effective Date and, unless earlier terminated as provided herein, shall expire on the second anniversary of the Effective Date or, if later, upon the completion of delivery of the Library to RPR. The license and other rights granted under Sections 2.5, 2.7, 2.8, 3.1, 3.2, 5.1, 5.2 and 5.3 shall survive such expiration, subject to compliance by RPR and its Affiliates with all limitations on the practice of such license rights set forth in such Sections. 8.2 TERMINATION BY RPR FOR FAILURE TO DELIVER.

(a) Failure by a Party to comply with any of its material obligations contained herein shall entitle the Party not in default to give to the Party in default notice specifying the nature of the default, requiring it to make good or otherwise cure such default, and stating its intention to terminate if such default is not cured. If such default is not cured within [*] after the date of such notice (or, if such default cannot be cured within such [*] period, if the Party in default does not commence and diligently continue actions to cure such default), the Party not in default shall be entitled, without prejudice to any of its other rights conferred on it by this Agreement, and in addition to any other remedies available to it by law or in equity, to terminate this Agreement; provided, however, that such right to terminate shall be stayed in the event that, during such [*], the Party alleged to have been in default shall have initiated dispute resolution proceedings in accordance with Section 9.11 with respect to the alleged default, which stay shall last so long as the initiating Party diligently and in good faith pursues the prompt resolution of such proceedings. (b) The right of a Party to terminate this Agreement, as provided above, shall not be affected in any way by its waiver or failure to take action with respect to any prior default. A Party may waive its right to terminate this Agreement with respect to a particular default, provided that any such waiver shall not constitute a waiver of, and such Party shall retain all rights to pursue, any and all other remedies it may have at law or in equity of such default by the other Party. 8.4 CONSEQUENCES OF TERMINATION.

(a) Termination or expiration of this Agreement for any reason shall be without prejudice to any rights which shall have accrued to the benefit of a Party prior to such termination or expiration.

The Parties agree that the Parties, as licensees of such rights under this Agreement, shall retain and may fully exercise all of their rights and elections under the U.S. Bankruptcy Code. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against either Party under the U.S. Bankruptcy Code, the Party hereto which is not a party to such proceeding shall be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, and same, if not already in their possession, shall be promptly delivered to them (i) upon any such commencement of a bankruptcy proceeding upon their written request therefor, unless the Party subject to such proceeding elects to continue to perform all of its obligations under this Agreement or (ii) if not delivered under (i) above, following the rejection of this Agreement by or on behalf of the Party subject to such proceeding upon written request therefor by the non-subject Party. 9.
