Indemnified Party of the potentially indemnifiable Third Party Claim (the Litigation Condition);
provided, that the Indemnifying Party expressly agrees the Indemnifying Party shall be responsible for satisfying and discharging any award made to the Third Party as a result of such proceedings or settlement amount agreed with the Third Party in
respect of the Third Party Claim without prejudice to any provision in this Agreement or right at law which will allow the Indemnifying Party subsequently to recover any amount from the Indemnified Party to the extent the liability under such
settlement or award was attributable to the Indemnified Party. Subject to compliance with the Litigation Condition, the Indemnifying Party shall retain counsel reasonably acceptable to the Indemnified Party (such acceptance not to be unreasonably
withheld, refused, conditioned or delayed) to represent the Indemnified Party and shall pay the fees and expenses of such counsel related to such proceeding. In any such proceeding, the Indemnified Party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party. The Indemnified Party shall not settle any claim for which it is seeking indemnification without the prior consent of the Indemnifying Party which
consent shall not be unreasonably withheld, refused, conditioned or delayed. The Indemnified Party shall, if requested by the Indemnifying Party, cooperate in all reasonable respects in the defense of such claim that is being managed and/or
controlled by the Indemnifying Party. The Indemnifying Party shall not, without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld, refused, conditioned or delayed), effect any settlement of any pending or
threatened proceeding in which the Indemnified Party is, or based on the same set of facts could have been, a party and indemnity could have been sought hereunder by the Indemnified Party, unless such settlement includes an unconditional release of
the Indemnified Party from all liability on claims that are the subject matter of such proceeding. If the Litigation Condition is not met, then neither Party shall have the right to control the defense of such Third Party Claim and the Parties shall
cooperate in and be consulted on the material aspects of such defense at the each Partys own expense; provided that if the Indemnifying Party does not satisfy the Litigation Condition, the Indemnifying Party may at any subsequent time during
the pendency of the relevant Third Party Claim irrevocably elect, if permitted by local procedural rules or laws, to defend and/or to control the defense of the relevant Third Party Claim so long as the Indemnifying Party also agrees to pay the
reasonable fees and costs incurred by the Indemnified Party in relation to the defense of such Third Party Claim from the inception of the Third Party Claim until the date the Indemnifying Party assumes the defense or control thereof.



11.4 Assumption of Defense. Notwithstanding anything to the contrary
contained herein, an Indemnified Party shall be entitled to assume the defense of any Third Party Claim with respect to the Indemnified Party, upon written notice to the Indemnifying Party pursuant to this Section 11.4, in which case the
Indemnifying Party shall be relieved of liability under Section 11.1 or 11.2, as applicable, solely for such Third Party Claim and related Losses.



11.5 Insurance. During the term of this Agreement and for a period of five (5) years after its termination, each party shall obtain and/or
maintain, respectively, at its sole cost and expense, liability insurance in amounts, respectively, as are the greater of: (i) required by applicable Laws and (ii) reasonable and customary in the U.S. pharmaceutical industry for companies of
comparable size and activities at the respective place of business of each Party, but in no event less than $10,000,000. Such liability insurance shall insure against all liability, including personal injury, physical injury, or property damage

purchase at least thirty-three and a third percent (33.33%) of Adolors API Compound requirements for a given Calendar Year from Supplier, Supplier agrees that for such Calendar Year (whether on its own behalf or with or on behalf of any
Person) it shall not, and shall not permit any of its Affiliates to:

providing technological assistance, expertise, manufacturing or supplies to any Person.



Nothing contained in this Section 14.2 is intended to be an implied license to or waiver of any patent or other intellectual property right.



14.3 Force Majeure. The occurrence of an event which materially interferes with the ability of a Party to perform its
obligations or duties hereunder which is not within the reasonable control of the Party affected or any of its Affiliates, not due to malfeasance by such Party or its Affiliates, and which could not with the exercise of due diligence have been
avoided (each, a Force Majeure Event), including an injunction, order or action by a Governmental Authority, fire, accident, labor difficulty, strike, riot, civil commotion, act of God, inability to obtain materials, delay or
errors by shipping companies or change in applicable Laws, shall not excuse such Party from the performance of its obligations or duties under this Agreement, but shall merely suspend such performance during the continuation of the Force Majeure
Event. The Party prevented from performing its obligations or duties because of a Force Majeure Event shall promptly notify the other Party of the occurrence and particulars of such Force Majeure Event and shall provide the other Party, from time to
time, with its best estimate of the duration of such



26



---

Force Majeure Event and with notice of the termination thereof. The Party so affected shall use commercially reasonable
efforts to avoid or remove such causes of nonperformance as soon as is reasonably practicable. Upon termination of the Force Majeure Event, the performance of any suspended obligation or duty shall promptly recommence. The Party subject to the Force
Majeure Event shall not be liable to the other Party for any direct, indirect, consequential, incidental, special, punitive, exemplary or other damages arising out of or relating to the suspension or termination of any of its obligations or duties
under this Agreement by reason of the occurrence of a Force Majeure Event, provided such Party complies in all material respects with its obligations under this Section 14.3.



14.4 Governing Law. This Agreement shall be construed, and the respective rights of the Parties determined, according
to the substantive Law of the Commonwealth of Pennsylvania notwithstanding the provisions governing conflict of Laws under such Pennsylvania Law to the contrary, except matters of intellectual property Law which shall be determined in accordance
with the intellectual property Laws relevant to the intellectual property in question. The UNCITRAL Convention for the International Sale of Goods, as well as any other unified Law relating to the conclusion and implementation of contracts for the
international sale of goods, shall not apply.



14.5
Jurisdiction. Any legal action or proceeding with respect to this Agreement shall be brought in the courts of the Commonwealth of Pennsylvania or of the United States District Court for the Eastern District of Pennsylvania, and, by execution
and delivery of this Agreement, each Party hereby irrevocably accepts the exclusive jurisdiction of the aforesaid courts. Each Party hereby further irrevocably waives any claim that any such court lacks jurisdiction over it or to the laying of
venue, and agrees not to plead or claim, in any legal action or proceeding with respect to this Agreement brought in any of the aforesaid courts, that any such court lacks jurisdiction over it or any such action or proceeding has been brought in an
inconvenient forum.



14.6 Assignment. This Agreement may
not be assigned by either Party without the prior consent of the other Party; provided, however, that either Party may assign this Agreement, in whole or in part, to any of its Affiliates provided that the assigning Party guarantees the performance
of this Agreement by such Affiliate; and provided further, that either Party may assign this Agreement to a successor to all or substantially all of the assets or line of business to which this Agreement relates whether by merger, sale of stock,
sale of assets or other similar transaction. This Agreement shall be binding upon, and subject to the terms of the foregoing sentence, inure to the benefit of the Parties hereto, their permitted successors, legal representatives and assigns.
