U.S.C. § 355(j)(2)(A)(vii)(IV) (as amended or replaced) with respect thereto. Par shall have the right to maintain its existing certifications under 21 U.S.C. § 355(j)(2)(A)(vii)(IV) (as amended or replaced) against the Licensed Patents.

 (c) The date on which the
Licensed Patents have all become expired, permanently abandoned, or delisted from the Orange Book; or

fide supply interruption; 2) caused by Plaintiffs changes to its wholesale distribution model, which effect does not last longer than a single quarter; or 3) caused by pharmacy benefit manager(s)’, insurer(s)’, or governmental payers’
utilization management practices, including, but not limited to, denial of formulary status or listing on a formulary exclusion list, which effect does not last longer than a single quarter. For the purposes of this provision, the “Threshold

order or preliminary injunction is issued against the Third Party seeking to sell the unauthorized Generic Product before [...***...] calendar days after such application (with the understanding that a subsequent

Settlement Agreement, currently in the possession of, or developed during the term of the Settlement Agreement by Par, Plaintiff or any of their respective Affiliates. The restrictions of this Section shall not apply to any Confidential Information
which (i) is already known to the recipient at the time of disclosure, as reasonably documented by written records; (ii) is or later becomes public knowledge through no fault of the recipient; (iii) is received from a Third Party
having the lawful right to disclose the information; or (iv) is independently developed by employees of the recipient without access to the disclosing Party’s Confidential Information.

provided to the other Party a copy of such announcement or disclosure and a reasonable opportunity to comment thereon; and provided that Par shall have the right to inform its customers that Par has obtained a license to sell a Generic Product in
the Territory. Notwithstanding the above, either Party may, without the permission of the other party, issue a press release disclosing that the litigation has settled by Par taking a license under the Licensed Patents and disclosing the License
Effective Date set forth in Section 6(a) of this Settlement Agreement. Each Party agrees that it shall cooperate fully with the other Parties with respect to all disclosures regarding this Settlement Agreement to any governmental or regulatory

prior to disclosing any terms of this Settlement Agreement. Such Party may then disclose the terms and conditions of this Settlement Agreement pursuant to such request, provided that it shall have used reasonable efforts to ensure that such
disclosure is subject to a protective order limiting access to the disclosure to outside counsel and expert witnesses of the entity receiving the Confidential Information. Nothing herein shall preclude any Party from complying with an order

 EXECUTION VERSION 

 

 
(a) an admission by Plaintiff as to the scope or interpretation of the claims of the Licensed Patents, nor (b) a representation or warranty that the Licensed Patents are valid and/or
enforceable. 
 17. Governing Law and Venue. This Settlement Agreement shall be governed by, and construed in accordance with, the
laws of the State of New Jersey, without regard for any conflict of law principles that would dictate the application of the laws of another jurisdiction. The Parties agree that the United States District Court for the District of New Jersey shall
have exclusive and sole jurisdiction to enforce any violation of this Settlement Agreement, except that, if for any reason that Court does not accept jurisdiction, then the state courts of New Jersey shall have exclusive and sole jurisdiction to
enforce any violation of this Settlement Agreement. The Parties hereby consent to the personal jurisdiction of those courts for any dispute arising from or relating to this Settlement Agreement. 

18. Severability. If any provision of this Settlement Agreement shall be held by a court of competent jurisdiction to be illegal,
invalid or unenforceable, the remaining provisions shall remain in full force and effect and the Parties shall negotiate in good faith to replace the invalid or unenforceable provision with a valid and enforceable provision that has the effect
nearest to that of the provision to be replaced. 
 19. Advice of Counsel. This Settlement Agreement has been negotiated by the
Parties and their respective counsel and shall be interpreted fairly in accordance with its terms and without any strict construction in favor of or against any Party. 

20. No Waiver. Waiver by a Party of any breach of any provision of this Settlement Agreement by another Party shall not operate or be
construed as a waiver of any subsequent or

 EXECUTION VERSION 

 

 
other breach. No provision of this Settlement Agreement may be waived except by a written instrument signed by the Party waiving compliance. 

21. Regulatory Delay. No provision of this Settlement Agreement shall be affected by any delay in the approval of the Par ANDA by the
FDA, or the failure of Par to obtain FDA approval of the Par ANDA. 
 22. [...***...] Expenses, and Costs and Fees.
[...***...], each Party shall bear its own attorneys’ fees and costs associated with the Lawsuits and the negotiation and preparation of this Settlement Agreement. 

23. Counterparts. This Settlement Agreement may be executed in one or more counterparts (including via facsimile or electronic copy),
each of which when so executed and delivered shall be deemed to be an original, but all of which taken together form but one and the same instrument. 

24. Headings. The headings and captions used in this Settlement Agreement are solely for the convenience of reference and shall not
affect its interpretation.

 25. Interpretation and Construction. The term “including” means
“including, without limitation,” and “herein,” “hereof,” and “hereunder” refer to this Settlement Agreement as a whole. The word “will” shall be construed to have the same meaning and effect as the
word “shall”. Except as otherwise expressly provided herein, references to any NDA or ANDA in this Settlement Agreement shall include such NDA or ANDA as it exists and is comprised as of the Effective Date, and any replacements or
successors or amendments or supplements to any of the foregoing. 
 26. Bankruptcy. All licenses and rights to licenses granted under
or pursuant to this Settlement Agreement by Plaintiff to Par are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses of rights to “intellectual property” as defined under
Section 101(35A) of the Bankruptcy Code. The Parties agree that Par, as a licensee of such rights under this Settlement Agreement, shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code, and that upon
commencement of a bankruptcy proceeding by or against Plaintiff under the Bankruptcy Code, Par shall be entitled to a complete duplicate of, or complete access to (as Par deems appropriate), any such intellectual property and all embodiments of such
intellectual property. Such intellectual property and all embodiments thereof shall be promptly delivered to Par (a) upon any such commencement of a bankruptcy proceeding upon written request therefor by Par, unless Plaintiff elects to continue
to perform all of its obligations under this Settlement Agreement by or on behalf of Plaintiff upon written request therefor by Par or (b) if not delivered under (a) above, upon the rejection of this Settlement Agreement by or on behalf of
Plaintiff upon written request therefor by Par. The foregoing provisions are without prejudice to any rights Par may have arising under the Bankruptcy Code or other applicable law.
