Licensor shall indemnify, defend and hold harmless Company and its Affiliates and each of their respective agents, employees, officers and directors (the “Company Indemnitees”) from and against any and all liability, damage, loss, cost or expense (including reasonable attorney’s fees) to the extent arising out of Third Party claims or suits (including Actions) related to: (a) Licensor’s negligence or willful misconduct; (b) Licensor’s provision of the cGMP Inventory (provided, that Licensor’s indemnification obligations with respect to the manufacture of such cGMP Inventory by the Third Party manufacturer shall be limited to such recoveries that Licensor is entitled to obtain from the Third Party manufacturer that manufactured such cGMP Inventory); or (c) breach by Licensor of this Agreement; provided, however, that Licensor’s obligations pursuant to this Section 9.2 shall not apply (i) to the extent that such claims or suits result from the negligence or willful misconduct of any of Company Indemnitees or (ii) with respect to claims or suits arising out of a breach by Company of this Agreement.

No Consequential Damages. EXCEPT WITH RESPECT TO A PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OR EACH PARTY’S INDEMNIFICATION OBLIGATIONS UNDER SECTION 9.1 OR SECTION 9.2, AS APPLICABLE, IN NO EVENT SHALL EITHER PARTY OR ANY OF ITS AFFILIATES BE LIABLE TO THE OTHER PARTY OR ANY OF ITS AFFILIATES FOR SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS, WHETHER IN CONTRACT, WARRANTY, TORT, NEGLIGENCE, STRICT LIABILITY OR OTHERWISE ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREIN OR ANY BREACH HEREOF.

Notification of Claims; Conditions to Indemnification Obligations.

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 or any indemnitee without the prior written consent of the indemnified Party. Each Party shall reasonably cooperate with the other Party and its counsel in the course of the defense of any such suit, claim or demand, such cooperation to include without limitation using reasonable efforts to provide or make available documents, information and witnesses. The indemnifying Party shall have no liability under this ARTICLE 9 with respect to claims or suits settled or compromised without its prior written consent.

Insurance. During the Term, each Party shall obtain and maintain, at its sole cost and expense, insurance (including any self-insured arrangements) in types and amounts, that are reasonable and customary in the United States pharmaceutical and biotechnology industry for companies engaged in comparable activities. It is understood and agreed that this insurance shall not be construed to limit either Party’s liability with respect to its indemnification obligations hereunder. Each Party will, except to the extent self-insured, provide to the other Party upon request a certificate evidencing the insurance such Party is required to obtain and keep in force under this Section 9.5.

Term and Expiration.

Effects of Termination.

Survival.

Licenses.

Termination on Bankruptcy or Insolvency. All rights and licenses granted under or pursuant to this Agreement by Licensor are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, if applicable, licenses of right to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that Company, as licensor of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code. The Parties further agree that, in the event of an Insolvency Event with respect to Licensor, Company 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, which, if not already in Company’s possession, shall be promptly delivered to it (i) following any such commencement of a bankruptcy proceeding upon Company’s written request therefor, unless Licensor elects to continue to perform all of its obligations under this Agreement or (ii) if not delivered under clause (a), following the rejection of this Agreement by Licensor upon written request therefor by Company.

Other Remedies. Termination of this Agreement for any reason shall not release either Party from any liability or obligation that already has accrued prior to such termination. Termination of this Agreement for any reason shall not constitute a waiver or release of, or otherwise be deemed to prejudice or adversely affect or limit, any rights or remedies that otherwise may be available at Law or in equity.

Escalation to Executive Officers. Either Party may, by written notice to the other Party, request that a dispute arising between the Parties in connection with this Agreement, or a dispute relating to material breach, be resolved by the Executive Officers, within [***] after referral of such dispute to them. If the Executive Officers cannot resolve such dispute within [***] after referral of such dispute to them, then, at any time after such [***] period, either Party may proceed to enforce any and all of its rights with respect to such dispute.

Injunctive Relief. Subject to Section 10.3, no provision herein shall be construed as precluding a Party from bringing an action for injunctive relief or other equitable relief prior to the initiation or completion of the above procedure.

Relationship of the Parties. Nothing in this Agreement is intended or shall be deemed, for financial, tax, legal or other purposes, to constitute a partnership, agency, joint venture or employer-employee relationship between the Parties.

Assignment. Except as expressly provided herein, neither this Agreement nor any interest hereunder shall be assignable, nor any other obligation delegable, by a Party without the prior written consent of the other Party, not to be unreasonably withheld or delayed; provided, however, that either Party may assign this Agreement, in whole or in part, without the consent of the other Party to (a) any Affiliate or (b) a Third Party in connection with a merger, acquisition of all or substantially all of the business or assets of such Party to which this Agreement relates, consolidation, change of control or other similar transaction. This Agreement shall be binding upon the successors and permitted assigns of the Parties. Any assignment not in accordance with this Section 12.2 shall be void. Licensor shall have the right to assign or transfer all, but not less than all, Licensed Technology to an Affiliate without the prior written consent of Company solely to the extent that Licensor also assigns and transfers this Agreement to such Affiliate.

Performance and Exercise by Affiliates. Company shall have the right to have any of its obligations hereunder performed, or its rights hereunder exercised, by, any of its Affiliates and the performance of such obligations by any such Affiliate shall be deemed to be performance by Company; provided, however, that Company shall be responsible for ensuring the performance of its obligations under this Agreement and that any failure of any Affiliate performing obligations of Company hereunder shall be deemed to be a failure by Company to perform such obligations. For clarity, the foregoing means that Company may designate an Affiliate to perform its obligations hereunder or to be the recipient of Licensor’s performance obligations hereunder.

Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments and to do all such other acts as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

Force Majeure. Neither Party shall be liable to the other Party or be deemed to have breached or defaulted under this Agreement for failure or delay in the performance of any of its obligations under this Agreement for the time and to the extent such failure or delay is caused by or results from acts of God, pandemic, earthquake, riot, civil commotion, terrorism, war, strikes or other labor disputes, fire, flood, failure or delay of transportation, omissions or delays in acting by a governmental authority, acts of a government or an agency thereof or judicial orders or decrees or restrictions or any other reason which is beyond the control of the respective Party. The Party affected by force majeure shall provide the other Party with full particulars thereof as soon as it becomes aware of the same (including its best estimate of the likely extent and duration of the interference with its activities), and will use Commercially Reasonable Efforts to overcome the difficulties created thereby and to resume performance of its obligations hereunder as soon as practicable.

No Trademark Rights. No right, express or implied, is granted by this Agreement to a Party to use in any manner the name or any other trade name or trademark of the other Party in connection with the performance of this Agreement or otherwise.

Entire Agreement of the Parties; Amendments. This Agreement and the Schedules hereto constitute and contain the entire understanding and agreement of the Parties respecting the subject matter hereof and cancel and supersede any and all prior negotiations, correspondence, understandings and agreements between the Parties, whether oral or written, regarding such subject matter.

Notices and Deliveries. Any notice, request, approval or consent required or permitted to be given under this Agreement shall be in writing and shall be deemed to have been sufficiently given if delivered in person, transmitted by facsimile (receipt verified) or by express courier service (signature required) to the Party to which it is directed at its address or facsimile number shown below or such other address or facsimile number as such Party shall have last given by notice to the other Party.

Waiver. A waiver by either Party of any of the terms and conditions of this Agreement in any instance shall not be deemed or construed to be a waiver of such term or condition for the future, or of any other term or condition hereof. All rights, remedies, undertakings, obligations and agreements contained in this Agreement shall be cumulative and none of them shall be in limitation of any other remedy, right, undertaking, obligation or agreement of either Party.

Severability. When possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under Law, but if any provision of this Agreement is held to be prohibited by or invalid under Law, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement. The Parties shall make a good faith effort to replace the invalid or unenforceable provision with a valid one which in its economic effect is most consistent with the invalid or unenforceable provision.

No Implied License. No right or license is granted to Licensor hereunder by implication, estoppel, or otherwise to any know-how, patent or other intellectual property right owned or controlled by Company or its Affiliates.
