exist and are pending review or approval by the CMC as contemplated by this Agreement, then either Party may call a meeting of the CMC on at least 30 days’ written notice to the other Party.

 8.5 Reduction Due to Generic Erosion. Generic Erosion for Licensed Products will be calculated on
a calendar quarterly basis. Gross sales information for Licensed Products and Generic Equivalents will be determined by using reference data published by IMS Health, Scott-Levin or another industry-accepted source used by Xcel at the time that such
determination is made. The reduced royalty set forth in the proviso in Section 8.3.1 will apply and be limited to each calendar quarter in which Generic Erosion exists, as documented by Xcel pursuant to this Section 8.5. Xcel will notify POZEN in
writing promptly upon its determination that Generic Erosion has occurred with respect to a calendar quarter and will provide with such notice such information and documentation as is reasonably necessary for POZEN to confirm the accuracy of such
determination. 
  
 8.6 Payments and Reports. Payments

such payment (or the delivery of any related report), adjustments will be made in subsequent payments (i.e., to “true-up” the aggregate amount of royalty payments made) and the reports made with respect to such subsequent payments
will indicate the basis and amount of any such adjustments. 
  
 8.7 Payment Method; Currency. Xcel will make all payments under this Agreement in United States dollars by wire transfer in immediately available funds to an account designated by POZEN. Any payments or portions thereof due hereunder

 9.4.4 Enforcement Costs and Awards. Each Party will bear its own costs incurred in connection with an action or proceeding brought by a Party pursuant to Section 9.4.2. In the case of an action or proceeding initiated by Xcel, any
resulting damage award, after reimbursement of each Party’s expenses, will be deemed Net Sales of Xcel in the Territory and will be subject to the royalty payment obligations set forth in Section 8.3. In the case of an action or proceeding
initiated by POZEN, any resulting damage award, after reimbursement of each Party’s expenses, will be shared between the Parties proportionate to each Party’s share of costs and expenses incurred in connection with such action or
proceeding.

legal theory, (b) the breach by Xcel of any of its representations, warranties or obligations contained in this Agreement, or (c) the gross negligence or willful misconduct of Xcel or its Affiliates. 
  
 11.2 Indemnification by POZEN. Except for Xcel’s indemnification
obligation as set forth in the preceding Section 11.1, and except to the extent caused by Xcel’s or its Affiliates’ negligent, reckless or willful acts or omissions, POZEN will indemnify, defend and hold Xcel and its directors, officers,
employees, agents and Affiliates harmless from and against any Losses which arise from any claim, lawsuit or other action to the extent such Losses arise out of, relate to or result from (a) the development, manufacture, use, or sale of any Licensed
Product prior to the Effective Date, including any product liability regardless of whether based on strict liability, breach of warranty, tort or other legal theory, (b) the development, manufacture, use, or sale of any Licensed Product or any

in respect of which the Indemnitee or any of its directors, officers, employees, and Affiliates intend to claim such indemnification within a reasonable period of time after the assertion of such claim; provided, however, that the failure to
provide written notice of such claim within a reasonable period of time will not relieve the Indemnitor of any of its obligations hereunder, except to the extent that the Indemnitor is prejudiced by such failure to provide prompt notice. The
Indemnitor will have the right to assume the complete control of the defense, compromise or settlement of any such claim without the prior written consent of such Indemnitee (although no settlement will be entered into concerning or affecting the
validity or enforceability of (a) the Licensed Technology or the Product Trademarks without the written consent of POZEN or (b) the Xcel Technology without the written consent of Xcel). The Indemnitor will, if it elects to assume control, at its own
expense employ legal counsel to defend the claim at issue. At any time after the Indemnitor has assumed defense of a claim, the Indemnitor may exercise, on behalf of the Indemnitee, any rights which may mitigate the extent or amount of such claim;
provided, however, that the Indemnitee: (x) may, in its sole discretion and at its own expense, employ legal counsel to represent it (in addition to the legal counsel employed by the Indemnitor) in any such matter, and in such event legal
counsel selected by the Indemnitee will be required to confer and cooperate with such counsel of the Indemnitor in such defense, compromise or settlement for the purpose

those employees, officers and directors of Indemnitee whose assistance, testimony or presence is necessary, useful or appropriate to assist the Indemnitor in evaluating and in defending any such claim; provided, however, that any such access
will be conducted in such a manner as not to interfere unreasonably with the operations of the businesses of Indemnitee; and (z) will otherwise fully cooperate with the Indemnitor and its legal counsel in the investigation and defense of such claim.

  
 11.4 Insurance. Each Party will maintain commercially
reasonable insurance coverage commensurate with its obligations under this Agreement. As regards Xcel, such commercially reasonable insurance coverage will include comprehensive general liability insurance coverage, including products liability
which carries a minimum limit of not less than US $10,000,000 upon the Commercial Launch of the Initial Licensed Product, and Xcel will provide POZEN with a certificate of insurance, naming POZEN as additionally insured, evidencing to POZEN such
coverage.

 IN NO EVENT WILL ANY PARTY BE LIABLE TO THE OTHER PARTY FOR LOST PROFITS,
LOSS OF DATA, OR FOR ANY SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES OF SUCH OTHER PARTY, HOWEVER CAUSED, ON ANY THEORY OF LIABILITY AND WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, ARISING

 13. CONFIDENTIALITY, PUBLICATIONS, PUBLICITY 

 
 13.1 Confidential Information. Any information or materials
communicated by one Party to the other Party pursuant to this Agreement or the Confidential Disclosure Agreement between the Parties dated February 27, 2003 will be deemed “Confidential Information” of the disclosing Party if (a)
such information or materials are marked “confidential” or with a similar legend, or (b) such information or materials, if disclosed orally or visually, are identified as being confidential at the time of such oral or visual
disclosure, and thereafter reduced to writing, marked “confidential” or with a similar legend, and sent to the other Party within 30 days of such oral or visual disclosure, or (c) such information or materials would, due to the nature
thereof or the circumstances surrounding disclosure, appear to a reasonable person to be confidential or proprietary. Notwithstanding the preceding sentence, “Confidential Information” will not be deemed to include information that the
receiving Party can demonstrate, by competent written proof: 
  
 13.1.1 At the time of disclosure is published or is publicly known or otherwise in the public domain, other than through any act or omission by the receiving Party;

 13.1.2 Was already known to the receiving Party, other than under an obligation of confidentiality
or non-use, prior to the time of disclosure; 
  
 13.1.3 Is
disclosed to the receiving Party in good faith, without an obligation of confidentiality, by a Third Party not under any obligation of confidence with respect to such information; or 
  
 13.1.4 Is independently developed by the receiving Party without use of or reference to the disclosing Party’s
Confidential Information. 
  
 13.2 Treatment of Confidential
Information. The Parties agree that during the Term and for 7 years after its expiration or termination for any reason whatsoever, a Party receiving Confidential Information of the other Party will: (a) treat any such Confidential Information
disclosed to it by the other Party as strictly confidential; (b) except as necessary in the performance of this Agreement, not disclose such Confidential Information to Third Parties without the prior written consent of the other Party, other than
to its Affiliates, collaborators or any consultants, provided that such disclosure be under confidentiality agreements with provisions comparable to those contained in this Agreement; (c) not use such Confidential Information for purposes other than
those authorized expressly herein; and (d) use reasonable efforts to prevent inadvertent disclosure of such Confidential Information. 
  
 13.3 Access. Access to Confidential Information will be limited to those employees or consultants of the Party receiving such information or of
such Party’s Affiliates who reasonably require such information in order to carry out activities authorized pursuant to this Agreement. Such employees or consultants will be advised of the confidential nature of the Confidential Information and
the related confidentiality undertaking. 
  
 13.4 Permitted
Disclosures. 
  
 13.4.1 Notwithstanding any other
provision in this Agreement, a receiving Party may disclose Confidential Information of the disclosing Party to the extent such disclosure is required by law or court order, provided that the receiving Party gives the disclosing Party prompt written
notice of the requirement to disclose and reasonably cooperates with the disclosing Party to seek a protective order or other restrictions on the disclosure of such Confidential Information of the disclosing Party. Any such required disclosure will
be limited

AND BRACKETS ([***]). A COMPLETE COPY OF THIS AGREEMENT, INCLUDING THE REDACTED PORTIONS, HAS BEEN SEPARATELY FILED WITH THE SECURITIES AND EXCHANGE COMMISSION. 








 only to that Confidential Information that is required to be disclosed and such disclosed Confidential Information will
remain Confidential Information hereunder despite the required disclosure. 
  
 13.4.2 Notwithstanding anything herein to the contrary, any Party (and any employee, representative, or other agent of any Party) may disclose to any and all persons, without limitation of any kind, the tax
treatment and tax structure of the transactions contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) that are provided to it relating to such tax treatment and tax structure; provided,
however, that no Party will be permitted to disclose such tax treatment or tax structure to the extent that such disclosure would constitute a violation of federal or state securities laws. For the purposes of the foregoing sentence, (i) the
“tax treatment” of a transaction means the purported or claimed federal income tax treatment of the transaction, and (ii) the “tax structure” of a transaction means any fact that may be relevant to understanding the purported or
claimed federal income tax treatment of the transaction. Thus, for the avoidance of doubt, the Parties acknowledge and agree that the tax treatment and tax structure of any transaction does not include the name of any Party to a transaction or any
sensitive business information (including, without limitation, the name and other specific information about any Party’s intellectual property or other proprietary assets) unless such information may be related or relevant to the purported or
claimed federal income tax treatment of the transaction. 
  
 13.5 Return of Confidential Information. Upon termination or expiration of this Agreement, each Party hereto and its Affiliates will return all Confidential Information of the other Party in their possession to the other Party;
provided, however, that each Party may retain: (a) a single archival copy of the Confidential Information of the other Party solely for the purpose of determining the extent of disclosure of Confidential Information hereunder and assuring
compliance with the surviving provisions of this Agreement; (b) any portion of the Confidential Information of the other Party which is contained in a Party’s laboratory notebooks; and (c) any portion of the Confidential Information of the
other Party which a Party is required by mandatory applicable law to retain. 
  
 13.6 Confidentiality of the Agreement Terms. Neither Party will disclose the terms of this Agreement to any Third Party without the prior written consent of the other Party; provided, however, that
either Party may disclose the terms of this Agreement (a) to actual or prospective investors and corporate partners, (b) to a Party’s accountants, attorneys and other professional advisors, and (c) as required by applicable laws and regulations
of the U.S. Securities and Exchange Commission, any stock exchange on which a Party’s stock is traded and any inter-dealer quotation system on which trading information for a Party’s stock is quoted. As part of any filing of this Agreement
pursuant to the foregoing clause (c), the filing Party will provide the other Party with the opportunity to review and comment on proposed redactions to this Agreement for purposes of such filing (although the filing Party will have no obligation in
the event that such redactions are not made or accepted as part of such filing).

 13.7 Publications. Except for Excepted Communications and information which has already been
published or is otherwise within the public domain, neither Party may present or publish research results arising from this Agreement, including, without limitation, any research results which relate to the use of the Licensed Technology in the
Field, whether in a thesis, scientific publication, conference or otherwise, without the prior written consent of the other Party. Intended presentations or publications will be presented in writing to the other Party in the English language for
review and comment at least 30 days prior to the time which the presentation or publication is proposed for submission to any Third Party. Within such 30-day period and at least 5 business days prior to the time which the presentation or publication
is proposed for submission to any Third Party, the other Party will provide notice whether it has any comments or objection to the proposed presentation or publication. The submitting Party will consider in good faith all comments by the reviewing
Party. If a reasonable objection is raised (because, for example, the contents of the presentation or publication contain patentable subject matter for which patent protection should be sought, or because the presentation or publication discloses
Confidential Information of the other Party which constitutes proprietary trade secrets or Know-How), then submission of the presentation or publication will be delayed, unless and until such time as consent to submission of the presentation or
publication is given. Each Party may be acknowledged on any publication or presentation by the other Party in accordance with generally accepted rules of authorship. 
  
 13.8 Publicity. Promptly following the Effective Date, the Parties will publish a mutually agreed joint press
release. Neither Party will make any public announcement concerning the existence of or the terms of this Agreement, without the prior written approval of the other Party with regard to the form, content and precise timing of such announcement,
except such as may be required to be made by either Party in order to comply with applicable law, regulations, court order, or tax or securities filings. Prior to any such public announcement, the Party wishing to make the announcement will submit a
draft of the proposed announcement to the other Party not less than 3 business days in advance to enable the other Party to consider and comment thereon. Notwithstanding anything to the contrary in this Agreement, nothing in this Section 13.8 is
intended to prohibit either Party from republishing or restating information relating to this Agreement that has already been approved by the other Party for use in a prior press release or public announcement. 
  
 14. TERM AND TERMINATION

position to assume such Commercialization or development prior to the termination date identified in the termination notice in accordance with this Section 14.4, such termination date will be accelerated upon POZEN’s request. 
  
 15. CONSEQUENCES OF TERMINATION 
  
 15.1 General. No termination of this Agreement will relieve any Party
from any liability which, at the time of such termination, has already accrued to the other Party or which is attributable to a period prior to such termination, nor preclude either Party from pursuing any rights and remedies it may have under this
Agreement or at law or in equity which accrued or are based upon any event occurring prior to such termination.

 16. DISPUTE RESOLUTION 
  
 16.1 Discussions. The Parties will try to settle their differences amicably between themselves. In the event of any controversy or claim arising
out of or relating to any provision of this Agreement or the performance or alleged non-performance of a Party of its obligations under this Agreement (a “Dispute”), a Party may notify the other Party in writing of such Dispute. If
the Parties are unable to resolve the Dispute within 20 days of receipt of the written notice by the other Party, such Dispute will be referred to the Chief Executive Officers of each of the Parties (or their respective designees) who will use their
good faith efforts to resolve the Dispute within 10 days after it was referred to the Chief Executive Officers. 
  
 16.2 Arbitration. 
  
 16.2.1 Any Dispute that is not resolved as provided in the preceding Section 16.1, whether before or after termination of this Agreement, will be
referred to binding arbitration under the rules of the American Arbitration Association, to the extent such rules are not inconsistent with this Section 16.2. Judgment upon the award of the arbitrators may be entered in any court having jurisdiction
thereof or such court may be asked to judicially confirm the award and order its enforcement, as the case may be. 
  
 16.2.2 The demand for arbitration will be made within a reasonable time after the Dispute has arisen, and in any event will not be made after the
date when institution of legal or equitable proceedings, based on such Dispute, would be barred by the applicable statute of limitations. The arbitration panel will consist of three (3) arbitrators, one (1) of whom will be appointed by each Party.
The two (2) arbitrators thus appointed will choose the third arbitrator; provided, however, that if the two (2) arbitrators are unable to agree on the appointment of the third arbitrator, either arbitrator may petition the American
Arbitration Association to make the appointment.

 16.2.3 The provisions of Federal Rules of Civil Procedure sections governing discovery are
incorporated in and made a part of this Agreement. Depositions may be taken and full discovery may be obtained in any arbitration commenced under this provision. 
  
 16.2.4 The arbitrators will, within 15 days after the conclusion of the arbitration hearing, issue a written award
and statement of decision describing the essential findings and conclusions on which the award is based, including the calculation of any damages awarded. The Arbitrator are authorized to award compensatory damages consistent with the terms of this
Agreement, but are NOT authorized (i) to award non-economic damages, such as for emotional distress, pain and suffering or loss of consortium, (ii) to award punitive damages, or (iii) to reform, modify or materially change this Agreement or any
other agreements contemplated hereunder; provided, however, that the damage limitations described in parts (i) and (ii) of this sentence will not apply if such damages are statutorily imposed. The arbitrators are authorized to grant any
temporary, preliminary or permanent equitable remedy or relief they deem just and equitable and within the scope of this Agreement, including, without limitation, an injunction or order for specific performance. 
  
 16.2.5 The place of arbitration will be New York, New York. Each Party
will bear and pay its own expenses incurred in connection with any dispute resolution under this Section 16.2. 
  
 16.3 Patents and Other Intellectual Property. Notwithstanding any provision of this Agreement to the contrary, any Dispute relating to a
Party’s intellectual property rights or Confidential Information will be submitted exclusively to any court of competent jurisdiction in the State of New York and, by execution and delivery of this Agreement, each party (a) accepts, generally
and unconditionally, the exclusive jurisdiction of such courts and any related appellate court, and irrevocably agrees to be bound by any judgment rendered thereby as contemplated by this Section 16.3, and (b) irrevocably waives any objection it may
now or hereafter have as to the venue of any such suit, action or proceeding brought in such a court or that such a court is an inconvenient forum. 
  
 17. MISCELLANEOUS 
  
 17.1 Further Assurances. At any time during the Term, Xcel and POZEN each will, at the request of the other Party, use reasonable efforts to (a)
deliver to the other Party such records, data or other documents consistent with the provisions of this Agreement, (b) execute, and deliver or cause to be delivered, all such assignments, consents, documents or further

 instruments of transfer or license, and (c) take or cause to be taken all such other actions, as a Party may reasonably
deem necessary or desirable in order for such Party to obtain the full benefits of this Agreement and the transactions contemplated hereby. 
  
 17.2 Assignment. Neither Party will assign its rights or obligations under this Agreement to any Third Party, without the prior written consent of
the other Party; except that either Party may assign such rights and obligations to a Third Party in connection with a merger, acquisition, consolidation, transfer or sale of all or substantially all of the assets of a Party (collectively, a
“Change of Control Event”) provided that such Third Party agrees in writing to be bound by all of the terms and conditions of this Agreement. All permitted assignments by either Party of any of its rights under this Agreement will
be subject to all of the terms and conditions of this Agreement. Any purported assignment not permitted under the terms of this Agreement will be null, void, and of no effect. Notwithstanding anything in this Agreement, the POZEN Know-How, POZEN
Improvements, and POZEN Patents, as well as the Xcel Know-How, Xcel Improvements, and Xcel Patents do not include any intellectual property held by a permitted successor prior to the Change of Control Event of the relevant Party. 
  
 17.3 Independent Contractors. The Parties are independent contractors.
Nothing contained herein will constitute either Party the agent of the other Party for any purpose whatsoever, or constitute the Parties as partners or joint venturers. Employees of each Party remain employees of said Party and will be considered at
no time agents of or owing a fiduciary duty to the other Party. Neither Party will have any implied right or authority to assume or create any obligations on behalf of or in the name of the other Party or to bind the other Party to any other
contract, agreement or undertaking with any Third Party. 
  
 17.4 Waiver. The failure of either Party to enforce any provision of this Agreement at any time will not be construed as a present or future waiver of such or any other provision of this Agreement. The express waiver by either Party
of any provision or requirement hereunder will not operate as a future waiver of such or any other provision or requirement and will be effective only if set forth in a written instrument signed by a duly authorized representative of the Party
waiving such provision or requirement. 
  
 17.5 Amendment.
The Parties may amend, modify or alter any of the provisions of this Agreement, but such amendment, modification or alteration will be valid and binding on either Party only if made by a written instrument that explicitly refers to this Agreement
and that is signed by a duly authorized representative of each Party. 
  
 17.6 Severability. In the event that any provision in this Agreement is held to be unlawful or invalid in any jurisdiction, the meaning of such provision will be construed to the greatest extent possible so as to render it
enforceable. If no such construction can render such

AND BRACKETS ([***]). A COMPLETE COPY OF THIS AGREEMENT, INCLUDING THE REDACTED PORTIONS, HAS BEEN SEPARATELY FILED WITH THE SECURITIES AND EXCHANGE COMMISSION. 








 provision enforceable, it will be severed. The remainder of this Agreement will remain in full force and effect, and the
Parties will negotiate in good faith a reasonable substitute provision that is valid and enforceable in such jurisdiction. If the Parties are unable to agree on a substitute provision, and if the unlawful or invalid provision was an essential
element of this Agreement without which one of the Parties would not have entered into this Agreement, as evidenced by this Agreement as a whole, then such Party may terminate this Agreement by written notice to the other Party effective upon
receipt. 
  
 17.7 Notice. All notices hereunder must be
given in writing and will be deemed given if delivered personally or by facsimile transmission (receipt confirmed), mailed by registered or certified mail (return receipt requested) with postage prepaid, or sent by express courier service (FedEx or
other reputable, internationally recognized courier service), to the Parties at the following addresses (or at such other address for a Party as will be specified by like notice; provided that notices of a change of address will be effective only
upon receipt thereof):

 17.8 Force Majeure. Neither Party will be deemed to be in breach of this Agreement as a result of
default, delay or failure to perform by such Party which is due to any cause beyond the reasonable control of such Party, including without limitation, fire, earthquake, acts of God, severe weather, acts of war, strikes, lockouts or other labor

notify the other Party, will use commercially reasonable efforts to overcome such force majeure, and will keep the other Party informed with respect thereto. If such force majeure continues for a period of more than 180 days, the Party not subject

counterpart of this Agreement. 
  
 17.10 Governing Law.
This Agreement will be governed by, and construed an interpreted in accordance with, the laws of the State of New York without giving effect to any choice of law rule that would cause the application of the laws of any jurisdiction other than the
internal laws of the State of New York to the right and duties of the Parties.

 EXHIBIT F 
  
 Co-Promotion Agreement Dispute Resolution Procedure 
  
 The Parties will enter into Dispute Resolution pursuant to Section 16.2 of the Agreement, although as part of any arbitration regarding the
negotiation of a co-promotion agreement pursuant to Section 5.3.2 of the Agreement, each Party will prepare and deliver to both the arbitrators and the other Party its proposed co-promotion agreement and a memorandum (the “Support
Memorandum”) in support thereof. The arbitrators will also be provided with a copy of the Agreement. Within 10 days after receipt of the other Party’s Support Memorandum, each Party may submit to the arbitrators (with a copy to the
other Party) a rebuttal to the other Party’s Support Memorandum, which may include a revision, marked to show changes, of either Party’s proposed co-promotion agreement. Neither Party may have communications (either written or oral) with
the arbitrators other than for the sole purpose of engaging the arbitrators or as expressly permitted in this paragraph. 
  
 Within 10 days after the Arbitration Commencement Date, the arbitrators will select from the two co-promotion agreements provided by the Parties the co-promotion
agreement that a majority of the arbitrators believe most accurately reflects the intention of the Parties to this Agreement and the industry customs regarding the co-promotion of comparable pharmaceutical products (the “Selected
Agreement”). The Selected Agreement will become a binding and enforceable agreement between POZEN and Xcel. 
  
 The arbitrators will have reasonable discretion to request additional information, hold a hearing, and extend the time frame for reaching their decision regarding the
dispute at issue. 
  
 The arbitrators’ fees and expenses will be paid by the
Party whose form of co-promotion agreement is not selected by the arbitrators. Each Party will bear and pay its own expenses incurred in connection with any dispute resolution under this Exhibit. 
  
 Except as noted, the other provisions relevant to Dispute Resolution will apply.
