(a)the amount of such recovery will first be applied to the Parties’ reasonable out-of-pocket costs incurred in connection with such proceeding (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses); then

(b)any remaining proceeds will be allocated as follows: (x) if Pfizer initiates or controls the defense of the proceeding, Pfizer will receive and retain [***], [***], or (y) if Akcea initiates or controls the defense of the proceeding, Akcea will receive and retain [***].

Pfizer will, at its discretion, promptly, accurately and completely list, with the applicable Regulatory Authorities commencing on the Closing Date and during the remainder of the Term, all applicable Akcea Patent Rights. Prior to such listings, the Parties will meet to evaluate and identify all applicable Patent Rights, and Pfizer will have the right to review, where reasonable, original records relating to any invention for which Patent Rights are being considered by Pfizer for any such listing. Notwithstanding the preceding sentence, Pfizer will retain final decision-making authority as to the listing of all applicable Akcea Patent Rights for the Product that are not Akcea Core Technology Patent Rights or Akcea Manufacturing Patent Rights, regardless of which Party owns such Patent Rights.

9.6Joint Research Agreement under the Xxxxx-Xxxxx America Invents Act. If a Party intends to invoke its rights under 35 U.S.C. § 102(c) of the Xxxxx-Xxxxx America Invents Act, it will notify the other Party and neither Party will make an election under such provision when exercising its rights under this ARTICLE 9 without the prior written consent of the other Party (such consent not to be unreasonably withheld, conditioned or delayed), and the Parties will use reasonable efforts to cooperate and coordinate their activities with such Party with respect to any submissions, filings or other activities in support thereof.

At the request of either Party, the other Party will reasonably consider in good faith whether a press release or other public disclosure described in this Section 10.4.1 should be a joint release by both Parties and, in such a case, the Parties will use good faith efforts to mutually agree on the content of any such joint release. Notwithstanding the foregoing, to the extent information regarding this Agreement has already been publicly disclosed, each Party (other than a Party that had caused such information to become publicly disclosed in breach of this ARTICLE 10) may subsequently disclose the same information to the public without the consent of the other Party.

In the event of concern over patent protection or whether maintaining a trade secret would be a priority, the publishing Party agrees not to submit such publication or to make such presentation that contains such information until the reviewing Party is given a reasonable period of time, and in no event more than 30 days, to seek patent protection for any material in such publication or presentation which it believes is patentable or to resolve any other issues. Notwithstanding anything herein to the contrary, none of Akcea, its Affiliates, its sublicensees, nor any licensee pursuant to a Permitted License entered into after the Execution Date may publish or publicly disclose any scientific data or results specific to the Compound, the Product, the Akcea Product-Specific IP or the Pfizer Product-Specific IP without Pfizer’s written consent, not to be unreasonably withheld, conditioned or delayed, and Akcea shall cause any such person to comply with this Section 10.5 as if it was a party hereto.

10.6Remedies. Each Party will be entitled to seek, in addition to any other right or remedy it may have, at Law or in equity, a temporary injunction, without the posting of any bond or other security, enjoining or restraining the other Party from any violation or threatened violation of this ARTICLE 10.

10.7Ongoing Obligation for Confidentiality. Upon expiration or termination of this Agreement, the Receiving Party shall destroy or return (as requested by the Disclosing Party) any Confidential Information of the Disclosing Party, except that the receiving Party (a) may retain a single copy of the Confidential Information for the sole purpose of (i) ascertaining its rights and responsibilities in respect of such Confidential Information and (ii) exercising its rights that expressly survive the expiration or termination of this Agreement and (b) shall not be required to destroy any computer files stored securely by the receiving Party that are created by automatic system back up.

12.3Procedure. A Person entitled to indemnification under this ARTICLE 12 (an “Indemnified Party”) will give prompt written notification to the Person from whom indemnification is sought (the “Indemnifying Party”) of the commencement of any Third Party Claim for which indemnification may be sought or, if earlier, upon the assertion of any such Third Party Claim (it being understood and agreed, however, that the failure by an Indemnified Party to give notice of a Third Party Claim as provided in this Section 12.3 will not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that such Indemnifying Party is actually damaged as a result of such failure to give notice). Within 20 Business Days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such Third Party Claim with counsel reasonably satisfactory to the Indemnified Party. If the Indemnifying Party does not assume control of such defense, the Indemnified Party will control such defense and, without limiting the Indemnifying Party’s indemnification obligations, the Indemnifying Party will reimburse the Indemnified Party for all costs and expenses, including attorney fees, incurred by the Indemnified Party in defending itself within 30 days after receipt of any invoice therefor from the Indemnified Party. The Party not controlling such defense may participate therein at its own expense; provided that, if the Indemnifying Party assumes control of such defense and the Indemnified Party in good faith concludes, based on advice from counsel, that the Indemnifying Party and the Indemnified Party have conflicting interests with respect to such Third Party Claim, the Indemnifying Party will be responsible for the reasonable fees and expenses of counsel to the Indemnified Party in connection therewith. The Party controlling such defense will keep the other Party advised of the status of such Third Party Claim and the defense thereof and will consider recommendations made by the other Party with respect thereto. The Indemnified Party will not agree to any settlement of such Third Party Claim without the prior written consent of the Indemnifying Party, which will not be unreasonably withheld, delayed or conditioned. The Indemnifying Party will not, without the prior written consent of the Indemnified Party, agree to any settlement of such Third Party Claim or consent to any judgment in respect thereof that does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any liability or obligation on the Indemnified Party or that acknowledges fault by the Indemnified Party.

12.4Insurance. Each Party will self insure or maintain, with insurers with a minimum “A-” AM Best rating, at its own cost, insurance against liability and other risks associated with its activities and obligations under this Agreement, including its Development, Manufacturing, Commercialization and other Exploitation activities, as applicable, and its indemnification obligations hereunder, in such amounts, subject to such deductibles, which are the sole responsibility of the named insured, and on such terms as are reasonable for a company such as such Party for the activities to be conducted by it under this Agreement, with minimum limits as specified below, which can be made up by any combination of primary and umbrella excess coverage. Each Party will promptly furnish to the other Party evidence of such insurance prior to the Closing Date and annually thereafter. Each Party will provide a minimum of 30 days written notice of any cancellation, with no replacement policy, to the other Party. All insurance of a Party will be primary and non-contributing to any insurance carried by the other Party, to the extent of the first Party’s indemnification obligations.

14.2Dispute Resolution.

If the Parties are unable to resolve the Dispute and any Party wishes to pursue its rights relating to such Dispute, then, except as otherwise expressly provided in this Agreement, the relevant Party will first submit the dispute to mediation within 30 days after written notice by one Party to the other demanding non-binding mediation.

Each of Pfizer and Akcea will nominate one of the three arbitrators from the JAMS list, and such nominees will together nominate the third arbitrator from the JAMS list. If either Pfizer or Akcea fails to nominate an arbitrator within 14 days after written notice by one Party to the other demanding arbitration, such arbitrator will be appointed by the chairman of JAMS. If the two arbitrators fail to agree upon a third arbitrator within 14 days after written notice of the nomination of the second arbitrator, the third arbitrator will be appointed by the chairman of JAMS. All parties to any arbitrated Dispute will share the costs of the arbitration equally, except that a party to the Dispute will bear its own costs and expenses, including attorney’s fees, witness fees, travel expenses, and preparation costs.

Nothing herein will restrict the ability of any Party to provide factual testimony during such proceedings. Notwithstanding the foregoing, any Party may seek an injunction or other equitable relief pending arbitration from any federal or state court of competent jurisdiction in New York State.

14.5Performance by Affiliates. Each Party hereby acknowledges and agrees that it will be responsible for the full and timely performance as and when due under, and observance of all the covenants, terms, conditions and agreements set forth in this Agreement by its Affiliate(s).

14.6Force Majeure. No Party will be held liable or responsible to the other Party nor be deemed to be in default under, or in breach of any provision of, this Agreement for failure or delay in fulfilling or performing any obligation (other than a payment obligation) of this Agreement when such failure or delay is due to force majeure.
