The fact that a particular item of information is not or has ceased to be Confidential Information by virtue of one or more of the exclusions specified in the definition of Confidential Information set forth in Section 1.15 (the “Excluded Item”) shall not relieve the Party who obtained or received the Excluded Item from that Party’s obligation of confidentiality and non-use (a) as to any other item of Confidential Information of the Other Party or (b) as to the relationship of the Excluded Item to any other item of Confidential Information of the Other Party.

10.1.3 Communication via Internet. Each Party agrees not to disseminate Confidential Information of the Other Party over the Internet or any similar form of electronic communication without the prior written approval of the Other Party; provided, however, that a Party may send Confidential Information over a secured, internal electronic mail system or over the Internet so long as such Confidential Information is encrypted and password protected.

10.1.4 Access to Confidential Information. Each Party hereby acknowledges that the Confidential Information of the Other Party is highly valuable, proprietary and confidential and that any disclosure to any officer, employee, or agent of such Party or any of its Affiliates shall be made only to the extent necessary to carry out its responsibilities or exercise its rights under this Agreement and only if such officer, employee or agent is informed of the confidential nature thereof and shall have agreed to hold such information in confidence under confidentiality provisions at least as stringent as those provided in this Agreement.

10.1.5 Equitable Relief. The Parties agree that the obligations of this Article 10 are necessary and reasonable in order to protect the Parties’ respective businesses, and that monetary damages alone may be inadequate to compensate a Party for any breach by the Other Party of its covenants and agreements set forth herein. The Parties agree that any breach or threatened breach of this Article 10 may cause irreparable injury to the injured Party for which Damages may not be an adequate remedy and that, in addition to any other remedies that may be available, in law and equity or otherwise, such Party shall be entitled to equitable relief against the breach or threatened breach of the provisions of this Article 10.

10.2 Public Announcements / Use of the Name. The Parties shall discuss the timing and contents of a press release to announce the fact of the execution of the this Agreement, achievement of each Research Milestone Event and Development Milestone Event for the progress of Collaborative Research, and make such press release if the Parties mutually agree upon the timing and contents; thereafter, ONO and Receptos may each disclose to any Third Party the information contained the contents in such press release without further approval of the Other Party. Neither Party shall use the name, trademark, tradename or logo of the Other Party, its Affiliates or their respective employees in any publicity, promotion, press releases or disclosure relating to this Agreement or its subject matter without the prior consent of the Other Party.

10.3 Other Permitted Disclosures. The receiving Party shall additionally be permitted to (i) disclose Confidential Information to actual or potential professional investors, acquirers, merger partners or retained professional advisors (e.g., attorneys, accountants, investment bankers), under confidentiality and non-use obligations at least as strict as those set forth herein; and (ii) issue statements and make disclosures that such Party determines to be necessary to comply with applicable law (including the disclosure requirements of the U.S. Securities and Exchange Commission, the NASDAQ stock market, the Osaka Securities Exchange or any other stock exchange on which securities issued by such Party are traded or proposed to be traded) or as appropriate in connection with an offer of securities.

10.4 Required Disclosure. The receiving Party shall be entitled to disclose Confidential Information where such disclosure is reasonably necessary to enforce its rights pursuant to this Agreement or where demand for such disclosure is made on the receiving Party pursuant to: (i) a valid order of a court or other governmental body; or (ii) any other applicable law; provided that if the receiving Party intends to make such disclosure or receives such demand, the receiving Party shall give the disclosing Party prompt notice of such fact to enable the disclosing Party to seek a protective order or other appropriate remedy concerning any such disclosure. The receiving Party shall fully co-operate with the disclosing Party at the disclosing Party’s expense in connection with the disclosing Party’s efforts to obtain any such order or other remedy. If any such order or other remedy does not fully preclude disclosure, the receiving Party shall make such disclosure only to the extent that such disclosure is legally required.

10.5 Solutions. Receptos agrees during the Target Exclusivity Period not to disclose to Third Parties Solutions for Collaboration Target developed pursuant to this Agreement without the prior written consent of ONO.

10.6 Publication. Except for disclosures permitted pursuant to Article X, in the event that Receptos wishes to publish or orally present information relating to any results arising from the Collaborative Research, including, without limitations, any results thereof, Receptos shall first submit to ONO all materials related to the proposed publication or presentation (including, without limitation, posters, abstracts, manuscripts and written descriptions of oral presentations) at least sixty (60) days prior to the date of submission for the draft publication and presentation. ONO shall review such submitted materials and respond to Receptos as soon as reasonably possible, but in any case within sixty (60) days of receipt thereof. ONO shall have the right (a) to propose modifications to publication or presentation for patent reasons, trade secret reasons or reasonable business reasons, (b) to request a reasonable delay in publication or presentation in order to protect patentable information, and (c) to reject Receptos’ publication with reasonable reason. If ONO requests a delay, Receptos shall delay submission or presentation for a period of up to sixty (60) days to enable patent applications protecting each Party’s right to be filed, or to resolve other reasonable business issues. If ONO requests modifications to a proposed publication or presentation, Receptos shall edit such publication or presentation to prevent disclosure of trade secret or proprietary business information prior to submission of the publication or presentation. In the event ONO does not respond within such sixty (60) day-period, Receptos shall be free to make such proposed publication or presentation. Further, should ONO make an objection to the publication or presentation, then the Parties shall discuss the advantages and disadvantages of publication or presentation. If the Parties are unable to agree on whether to publish the same, the Chief Executive Officer of Receptos and the Executive Officer in Research Headquarters of ONO shall use reasonable efforts to agree upon the contents to be submitted for the publication or presentation.

debtor Party upon written request therefor by the non-debtor Party. The Parties agree that notwithstanding the foregoing, in the event of an insolvency or bankruptcy of ONO in Japan, (i) Japanese law shall govern all applicable insolvency or bankruptcy proceedings with respect to ONO and (ii) to the maximum extent permitted by applicable law, in any bankruptcy proceeding by or against a Party under the Japanese bankruptcy law, the non-debtor Party shall retain the licenses and other rights granted to it hereunder and may continue to exercise such rights in accordance with the terms and conditions of this Agreement, irrespective of whether or not the debtor Party elects to rescind this Agreement pursuant to Article 53 of the Japanese bankruptcy law (or any comparable provision of other Japanese laws applicable to bankruptcies or insolvencies).

12.2 Indemnification by Receptos. In addition to any other rights ONO may have at law or in equity, Receptos shall indemnify, defend and hold harmless ONO, its Affiliates, Research Partners and Licensees, and their respective employees, officers and directors, and their successors and assigns thereof (each, an “ONO Indemnified Party”), from and against any and all Damages which the ONO Indemnified Party may incur, suffer or be required to pay to the extent resulting from or arising out of Claims by a Third Party arising from any material breach of any representation, warranty or covenant of Receptos in this Agreement; except, in each case, to the extent of indemnification obligations of ONO under Section 12.1.

12.3 Conditions of Indemnification of Third-Party Claims. The obligations and liabilities of an indemnifying Party under Section 12.1 or 12.2 hereof with respect to Damages resulting from Claims by Third Parties shall be subject to the following terms and conditions:

12.3.1 Procedures. Promptly after the delivery of a notice seeking indemnification in respect of a Claim and subject to Section 12.4, the indemnifying Party may elect, by written notice to the indemnified party, to undertake the defense thereof, at the sole cost and expense of the indemnifying Party. If the indemnifying Party chooses to defend any Claim, the indemnified party (either ONO Indemnified Party or Receptos Indemnified Party as the case may be) shall cooperate with all reasonable requests of the indemnifying Party and shall make available to the indemnifying Party any witnesses, books, records or other documents within its control that are necessary or appropriate for such defense.

12.3.2 Control of Defense by Indemnified Party. In the event that the indemnifying Party, within a reasonable time after receipt of a notice seeking indemnification, does not so elect pursuant to Section 12.3.1 to defend such Claim, the indemnified party (either ONO Indemnified Party or Receptos Indemnified Party as the case may be) shall have the right (upon further notice to the indemnifying Party) to undertake the defense, compromise or settlement of such Claim for account of the indemnifying Party, subject to the right of the indemnifying Party to assume the defense of such Claim pursuant to the terms of Section 12.3.1 at any time prior to settlement, compromise or final determination thereof, provided, that the indemnifying Party reimburses in full all costs, including but not limited to reasonable attorney’s fees and expenses, incurred by the indemnified party (either ONO Indemnified Party or Receptos Indemnified Party as the case may be) in connection with such defense prior to such assumption.

12.3.3 Participation of Indemnified Party in Defense. Notwithstanding anything in this Article to the contrary, if the indemnifying Party assumes the defense of any Claim, any indemnified party (either ONO Indemnified Party or Receptos Indemnified Party as the case may be) shall be entitled to participate in the defense, compromise or settlement of such Claim with counsel of its own choice at its own expense, provided, however, if the representation of the Parties by the indemnifying Party’s counsel would present a conflict of interest between the Parties, then such indemnified party (either ONO Indemnified Party or Receptos Indemnified Party as the case may be) shall be entitled to participate in the defense, compromise or settlement of such Claim with counsel of its own choice at the expense of the indemnifying Party.

12.4 Settlements. No person who has undertaken to defend a Claim under Section 12.3.1 or 12.3.2 shall, without written consent of all indemnified parties (either ONO Indemnified Parties or Receptos Indemnified Parties as the case may be), settle or compromise any Claim or consent to entry of any judgment, provided, however, that such consent shall not be required if such settlement, compromise or judgment (i) includes as an unconditional term thereof the release by the claimant or the plaintiff of all indemnified parties from all liability arising from events which allegedly gave rise to such Claim and (ii) contains no restriction, limitation or prohibition of any kind on the manner in which any indemnified party (either ONO Indemnified Party or Receptos Indemnified Party as the case may be) conducts its business. Any payment made by an indemnified party (either ONO Indemnified Party or Receptos Indemnified Party as the case may be) to settle a Claim against it without obtaining consent of the indemnifying Party shall be at its own cost and expense. Notwithstanding the foregoing, the indemnifying Party shall be liable under this Section for any settlement effected without its consent if the indemnifying Party has refused to acknowledge liability for indemnification hereunder and/or declines to defend the indemnified party (either ONO Indemnified Party or Receptos Indemnified Party as the case may be) in any such Claim, action or proceeding and it is determined that the indemnifying Party was liable to the indemnified party (either ONO Indemnified Party or Receptos Indemnified Party as the case may be) for indemnification related to such settlement.

12.5 Disclaimer of Consequential Damages. IN NO EVENT SHALL EITHER RECEPTOS OR ONO BE LIABLE TO THE OTHER PARTY FOR ANY SPECIAL, INDIRECT, CONSEQUENTIAL, INCIDENTAL, OR PUNITIVE DAMAGES ARISING UNDER OR AS A RESULT OF THIS AGREEMENT (OR THE TERMINATION HEREOF) INCLUDING THE LOSS OF PROSPECTIVE PROFITS OR ANTICIPATED SALES, OR ON ACCOUNT OF EXPENSES, INVESTMENTS, OR COMMITMENTS IN CONNECTION WITH THE BUSINESS OR GOODWILL OF ONO OR RECEPTOS OR OTHERWISE, EXCEPT TO THE EXTENT ANY SUCH DAMAGES (I) ARE PAID TO A THIRD PARTY AS PART OF AN INDEMNIFIED THIRD PARTY CLAIM UNDER AND IN ACCORDANCE WITH ARTICLE XII OR (II) RESULT FROM A BREACH OF ANY CONFIDENTIALITY, NON-USE OR NONDISCLOSURE OBLIGATIONS UNDER ARTICLE X.
