11.2Indemnification by Receptos. In addition to any other rights Company may have at law or in equity, Receptos will indemnify, defend and hold harmless Company and its Affiliates and their respective employees, officers and directors, and their successors and assigns (each, a “Company Indemnified Party”), from and against any and all Damages which the Company Indemnified Party may incur, suffer or be required to pay to the extent resulting from or arising out of Claims based on any material breach of any representation, warranty or covenant of Receptos in this Agreement, except to the extent such Damages arise from Claims by Third Parties: (x) based on any material breach, including a breach of any representation, warranty or covenant, of Company in this Agreement; or (y) based on the negligence, gross negligence or willful misconduct of a Company Indemnified Party.

11.3Conditions of Indemnification of Third-Party Claims. The obligations and liabilities of an indemnifying party under Section 11.1 or 11.2 hereof with respect to Damages resulting from Claims by Third Parties will be subject to the following terms and conditions:

11.3.1Promptly after the delivery of a notice seeking indemnification in respect of a Claim and subject to Section 11.3.3, 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 shall cooperate with all reasonable requests of the indemnifying party and shall make available to the indemnifying party any books, records or other documents within its control that are necessary or appropriate for such defense.

11.3.2In the event that the indemnifying party, within a reasonable time after receipt of a notice seeking indemnification, does not so elect to defend such Claim, the indemnified party will have the right (upon further notice to the indemnifying party) to undertake the defense, compromise or settlement of such Claim for the 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 11.3.1 at any time prior to settlement, compromise or final determination thereof, provided that the indemnifying party reimburses in full all costs of the indemnified party (including reasonable attorney’s fees and expenses) incurred by it in connection with such defense prior to such assumption.

11.3.3Notwithstanding anything in this Section 11.3 to the contrary, if the indemnifying party assumes the defense of any Claim, any indemnified party will 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 by the indemnifying party’s counsel would present a conflict of interest, then such indemnified party 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.

11.4Settlements. No person who has undertaken to defend a Claim under Sections 11.3.1 or 11.3.2 will, without written consent of all indemnified parties, settle or compromise any Claim or consent to entry of any judgment, provided, however, that such consent will 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 conducts its business. Any payment made by a party to settle a Claim against it without obtaining consent of the indemnifying party will be at its own cost and expense. Notwithstanding the foregoing, the indemnifying party will be liable under this Article XIII 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 in any such Claim, action or proceeding and it is determined that the indemnifying party was liable to the indemnified party for indemnification related to such settlement.

11.5Disclaimer of Consequential Damages. IN NO EVENT WILL EITHER RECEPTOS OR COMPANY BE LIABLE TO THE OTHER 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 COMPANY OR RECEPTOS OR OTHERWISE, EXCEPT TO THE EXTENT ANY SUCH DAMAGES (I) ARE PAID TO A THIRD PARTY AS PART OF A THIRD PARTY CLAIM OR (II) RESULT FROM THE BREACH OF A CONFIDENTIALITY, NON-USE OR NON-DISCLOSURE OBLIGATION SET FORTH HEREIN.

XII.     DISPUTE RESOLUTION

12.1Mediation. Any controversy or claim arising out of or relating to this Agreement, including any such controversy or claim involving the parent company, subsidiaries, or Affiliates of any party (a “Dispute”), shall first be submitted to mediation according to the Commercial Mediation Procedures of the American Arbitration Association (“AAA”) (see www.adr.org). Such mediation shall be attended on behalf of each party for at least one session by a senior business person with authority to resolve the Dispute. Any period of limitations that would otherwise expire between the initiation of a mediation and its conclusion shall be extended until 20 days after the conclusion of the mediation.

12.2Arbitration. Any Dispute that cannot be resolved by mediation within 45 days of notice by one party to the other of the existence of a Dispute (unless the parties agree to extend that period) shall be resolved by arbitration in accordance with the Commercial Arbitration Rules of the AAA (“AAA Rules”; see www.adr.org) and the Federal Arbitration Act, 9 U.S.C. §1 et seq. The arbitration shall be conducted in New York, by one arbitrator appointed in accordance with the AAA Rules.

12.2.1The arbitrator shall follow the ICDR Guidelines for Arbitrators Concerning Exchanges of Information in managing and ruling on requests for discovery.

12.2.2The arbitrator, by accepting appointment, undertakes to exert her or his best efforts to conduct the process so as to issue an award within eight months of her or his appointment, but failure to meet that timetable shall not affect the validity of the award.

12.2.3The arbitrator shall decide the Dispute in accordance with the substantive law of New York. The arbitrator may not award punitive or consequential damages, nor may the arbitrator apply any multiplier to any award of actual damages, except as may be required by statute. The award of the arbitrator may be entered in any court of competent jurisdiction.

12.3Intellectual Property and Equitable Relief. Notwithstanding any provision in this Article XIV to the contrary: (i) any dispute relating to the scope or validity of any patent or other issues relating to intellectual property may be submitted directly to a federal court with jurisdiction; and (ii) any party may seek injunctive relief from a court with jurisdiction to prevent irreparable harm (including, without limitation, pending the conclusion of any mediation or arbitration).
