negotiations with POZEN regarding such Field expansion, then POZEN will be free after the OTC Approval Event to register and Commercialize a GSK OTC Product alone or with or through a Third Party; provided, however, that if GSK engaged
in good faith negotiations under this subsection and the Parties are unable to execute an agreement prior to the termination or expiration of the Negotiation Period, POZEN will not, for a period of [***] from the termination or expiration of the
Negotiation Period, enter into a license or other agreement with a Third Party providing for the commercialization of a GSK OTC Product on terms which are in the aggregate less favorable to POZEN than the last bona fide offer made in writing
by POZEN to GSK (an “Alternative Agreement”). If POZEN desires to enter into an Alternative Agreement with a Third Party during such [***] period, then it will first offer the terms and conditions of the Alternative Agreement to GSK
and give GSK the right to enter into a definitive agreement with POZEN upon such terms and conditions within [***] from the date of such offer. If GSK does not enter into a definitive agreement having the terms and conditions of the Alternative
Agreement within such period, then POZEN will be free to enter into the Alternative Agreement with the Third Party upon the terms and conditions of the Alternative Agreement.

 in this Section 2.7, Section 3.4(c), Section 9.6, Article 10, Article 11, Article 13 and Article 14 (and Section 12.5 in
respect of the survival of the foregoing provisions), the Parties acknowledge and agree that this Agreement will not become effective until such date as the waiting period under the Hart-Scott-Rodino Anti-Trust Improvements Act of 1976, as amended
(the “HSR Act”), has expired or otherwise terminated, (the “Effective Date”). Each Party will cooperate with the other and use its commercially reasonable efforts to make any initial filings required under the HSR
Act and subsequent filings required in the event that a Second Request is received under the HSR Act (a “HSR Second Request”). Upon the date [***] following the receipt of a HSR Second Request, the obligations of the Parties under
this Agreement will terminate and no longer be in force in effect unless the Parties mutually agree otherwise in writing. In the event (i) the Agreement is terminated after the expiration of such [***] period pursuant to this Section 2.7; (ii) the
Federal Trade Commission (the “FTC”) declines to grant approval for the Agreement to become effective; or (iii) GSK discontinues seeking FTC approval for the Agreement after receipt of a HSR Second Request (in which case it will
promptly provide notice of which to POZEN), then GSK will [***]. Upon the occurrence of events described in the preceding clause (i) or (ii) or any notification by GSK pursuant to the preceding clause (iii), the obligations of the Parties under this
Agreement effective as of the Execution Date will terminate and be of no further force and effect, except for [***] under this Section 2.7, Article 11 (other than Section 11.6 and Section 11.7) and Article 14. 
  
 3. PRODUCT DEVELOPMENT. 
  
 3.1 General. During the Term, POZEN will be solely responsible for,
and will bear all costs and expenses associated with, the pre-commercialization development and regulatory registration of the Lead Product in the Territory, except as otherwise provided in this Agreement. During the Term, GSK will be solely
responsible for, and will bear all costs and expenses associated with, the post-approval development of Collaboration Products, the development of Other Products, and the manufacturing and Commercialization of the Collaboration Products in the
Territory, except as otherwise provided in this Agreement. In addition, GSK will be responsible for developing the Formulation. All activities conducted by POZEN and GSK in connection with the development of the Lead Product will be undertaken in
accordance with the Development Plan. POZEN agrees not to conduct (nor license or grant rights to a Third Party to conduct) any studies in [***] pursuant to Section [***]. 
  
 3.2 Development Program and Plan. 
  
 (a) The Development Program for the solid oral dose of MT 400 in the Dosage Strength will be performed by POZEN and
GSK in accordance with the Development Plan. The Parties agree and acknowledge that the Development Plan integrates the pre-clinical and clinical development activities relating to the solid oral dose of MT 400 in the Dosage Strength to be performed
by POZEN during the Term (such activities referred to herein as the

 “POZEN Development Activities”) and the development of the solid oral dose of the Formulation of MT 400
in the Dosage Strength and provision of Clinical Trial Materials to be performed by GSK (such activities referred to herein as the “GSK Development Activities”). The Development Plan includes an overall timeline of the estimated
target dates for completing the various development tasks described within the Development Plan (the “Development Timeline”) with such timeline comprising the timeline for the GSK Development Activities (the “Formulation
Development Timeline”) and the POZEN Development Activities (the “POZEN Development Timeline”). Promptly following the Effective Date, the Parties agree that the Joint Project Team will (i) adjust the Development Timeline
to account for the delay (if any) to the start of the Development Timeline and the date this Agreement becomes effective; and (ii) adjust the POZEN Development Timeline to allow for identification testing, randomization, and clinical patient
labeling of Clinical Trial Materials by POZEN in accordance with Section 3.6(c) below, each subject to Section 3.2(b) below. The Parties agree and acknowledge that commencement of the POZEN Development Activities (e.g., the Phase III Clinical
Trials) that are contingent upon receipt of Clinical Trial Material from GSK will be extended (and the POZEN Development Timeline in respect of such activities will be adjusted) to account for the date on which such Clinical Trial Materials are
actually received by POZEN (in accordance with Section 3.2(b) below) and that subsequent POZEN Development Activities will likewise be extended by any delay caused by GSK’s failure to timely deliver such Clinical Trial Materials. The Parties
agree and acknowledge that the Development Plan, POZEN Development Activities, GSK Development Activities, Development Timeline, Formulation Development Timeline and the POZEN Development Timeline apply only to the solid oral dose of MT 400 in the
Dosage Strength, but that the foregoing terms will be used herein to also apply mutatis mutandis to any Other Product in the event that the Parties substitute the solid oral dose of MT 400 in the Formulation as the Lead Product in accordance
with Section 3.3.  
  
 (b) The Parties will work
together, through their participation on the Joint Project Team, to evaluate from time to time in light of then-current circumstances the status of the Development Program and progress compared to the Development Timeline and the Formulation
Development Timeline. Either GSK or POZEN may propose modifications to the Development Plan which will be discussed by the Joint Project Team. Any modification to the Development Plan proposed by either Party (except for Regulatory Amendments
(defined below)) that will extend the Development Timeline [***] or [***] associated with the development of the Lead Product (each, a “Material Amendment”) will require the requesting Party to demonstrate that the potential
economic benefits to both Parties that may result from the proposed Material Amendment materially outweigh the potential adverse economic impact on both Parties (including, the impact caused by a delay in launch and any increased development costs)
associated with such proposed Material Amendment. Each Material Amendment will require the unanimous approval of the Joint Project Team prior to implementation by POZEN and any dispute regarding Material Amendments will be subject to the procedures
described on Schedule 4.5. The Joint Project Team also will review and consider any modifications to the

 Development Plan suggested or required by the FDA (each, a “Regulatory Amendment”) and POZEN will amend
the Development Plan as necessary to incorporate feedback from the FDA on the Development Program and to comply with any legal requirement or formal action imposed by the FDA. If GSK disagrees with any such Regulatory Amendment, then such dispute
will be subject to the procedures described on Schedule 4.5. Notwithstanding anything to the contrary herein, POZEN will have the right, at its discretion, to continue or suspend its performance of its obligations under the Development Plan
for the time period of any dispute between the Parties regarding an amendment to the Development Plan only with respect to [***], and will continue its performance of its obligations under the Development Plan for the time period of any dispute with
respect to any Material Amendment or suggested Regulatory Amendment, unless otherwise agreed by the Parties. The Parties will agree in advance on an anticipated budget for any Material Amendment and Regulatory Amendment. The Parties acknowledge that
such Project Costs will be reduced by the costs not otherwise incurred by POZEN, if any, resulting from the replacement by the Joint Project Team of any study included as part of the POZEN Development Activities in the Initial Development Plan with
an alternative study as part of such Material Amendment or Regulatory Amendment and that such Project Costs are outside the scope of this Agreement. GSK will pay POZEN’s Project Costs for the Project Activities associated with such Material
Amendment or Regulatory Amendment not later than 15 days following the receipt of an invoice from POZEN, it being understood that such invoices will be payable directly to POZEN and will be based upon the payment amount (or an invoice, if available)
agreed between POZEN and a Third Party contractor engaged by POZEN to perform the Project Activities.  
  
 (c) Promptly following the Effective Date, the Joint Project Team will meet to review the proposed clinical trial protocol applicable to MT 400 and
POZEN will use its commercially reasonable efforts to submit such protocol to the FDA and arrange a meeting (either in person or by other appropriate means) with representatives of POZEN, GSK and the FDA, in accordance with the FDA’s Guideline
for Special Protocol Assessment. Each Party will cooperate with the other and use its commercially reasonable efforts in connection with such meeting as necessary and consider any changes to the protocol proposed by the FDA. 
  
 3.3 Substitution of Lead Product. 
  
 (a) GSK may request in writing that an Other Product (in lieu of a
solid oral dose of MT 400 in the Dosage Strength) be designated as a new Lead Product at any time prior to the date that is [***] as the Lead Product if it is Commercially Reasonable to do so. Promptly upon receipt of such request, the Joint Project
Team will meet to discuss such substitution and to establish a Development Plan and Development Timeline for such Lead Product. If the Joint Project Team cannot reach consensus on such substitution and Development Plan within 60 days, the matter
will be subject to the dispute resolution process provided in Section 13.1(a). If after the completion of such process, the Parties are still unable to agree, the final decision on the matter will be made by the GSK members of the Joint Project
Team. GSK will have the right to substitute the Lead Product only once.

 (b) In connection with the designation of an Other Product as a Lead Product in accordance with
this Section 3.3, POZEN [***] such Lead Product under this Agreement [***], as determined in its reasonable discretion. POZEN [***] in accordance with the terms of this Agreement and the Parties will agree to amend this Agreement such that (A) GSK
will pay POZEN’s Project Costs for such Project Activities for such Lead Product covering the period from the designation of the Other Product as the Lead Product to the date immediately prior to receipt from GSK of the [***] of such Lead
Product and (B) GSK thereafter will pay the development milestones for such Lead Product described in Section 7.2 hereof; provided, however, that the Parties agree that such amended agreement [***] GSK’s payment obligation to
POZEN and that the remaining terms and conditions of this Agreement will not be otherwise amended unless mutually agreed in writing by the Parties. The Parties will agree through the Joint Project Team in advance on an anticipated budget for any
such development obligations of POZEN, and GSK will pay [***] for the Project Activities associated with such development activities not later than 15 days following the receipt of an invoice from POZEN, it being understood that such invoices will
be payable directly to POZEN, and with respect to out-of-pocket costs for materials or services provided by Third Parties will be based upon [***] agreed between POZEN and a Third Party contractor engaged by POZEN to perform the Project Activities.
The Parties will create a new Development Plan for the new Lead Product (and all plans and timelines referenced in Section 3.2(a)) and will amend this Agreement as necessary if the Parties substitute the Lead Product in accordance with this Section
3.3.  
  
 (c) If a Product Failure has not occurred
and GSK has elected to substitute the Lead Product, upon receipt of the substitution request from GSK pursuant to subsection (b), then with regard to MT 400 and effective as of the date of such receipt (the “Substitution Date”):

  
 (i) the licenses and rights granted by POZEN under
this Agreement will terminate immediately as to MT 400 and revert to POZEN (and the definition of “Product” will automatically be amended to exclude MT 400 thereafter); 
  
 (ii) GSK will promptly transfer and deliver to POZEN all (A) GSK’s then-current MT 400 supply, if any,
(including, without limitation, all Clinical Trial Materials), and (B) all documented GSK Know-How concerning MT 400 then in GSK’s possession or control (including, without limitation, all data from non-clinical and clinical studies,
CMC-related information and Formulation information). 
  
 (iii) Effective upon the Substitution Date, 
  
 (1) GSK hereby grants to POZEN a [***] license, with the right to grant and authorize the grant of sublicenses, under any GSK Patents and GSK Know-How that constitute Product Specific Improvements to develop, make, have made, use,
sell, offer for sale and import MT 400.

 (2) GSK hereby grants to POZEN a [***] license, with the right to grant and authorize the grant
of sublicenses, under any GSK Formulation Technology to develop, make, have made, use, sell, offer for sale and import Collaboration Products in the Formulation at the Dosage Strength containing MT 400 so long as GSK is obligated to supply POZEN
with Clinical Trial Materials or commercial quantities of Collaboration Products in the Formulation containing MT 400 under this Agreement. In the event GSK is not obligated to supply POZEN with Clinical Trial Materials or commercial quantities of
Collaboration Products in the Formulation containing MT 400 under this Agreement and POZEN requests a license to the GSK Formulation Technology, the license granted in this Section 3.3(c)(iii)(2) will be royalty bearing and the royalty will be equal
to [***]% of Net Sales of such Collaboration Product in the Formulation containing MT 400. The term of such royalty bearing license will be the longer of 10 years from the date of first commercial sale or the term of any Patent Controlled by GSK
infringed by the manufacture or sale of such Collaboration Product containing the GSK Formulation Technology. 
  
 (3) Any sublicense of a right granted to POZEN under this Section 3.3(c) will be made subject to the terms of this Agreement and any action or
omission by such sublicensee that would, if committed by POZEN, constitute a breach of this Agreement, will be deemed a breach of this Agreement by POZEN. POZEN will impose on any sublicensee obligations corresponding to POZEN’s obligations
hereunder. 
  
 (iv) GSK will assign to POZEN, to the
extent fully assignable and at POZEN’s request, GSK’s rights in any or all Third Party agreements for licenses, services or supplies necessary for the development or Commercialization of MT 400, including, without limitation, any
agreements with a Third Party regarding the GSK Formulation Technology. To the extent that any agreement is not fully assignable by GSK, then such agreement will not be assigned, and upon the request of POZEN, GSK will cooperate in good faith and
use commercially reasonable efforts to allow POZEN to obtain and to enjoy the benefits of such agreement in the form of a license or other right to the extent held by GSK subject to such Third Party’s rights.  
  
 (v) Upon the request of POZEN to be provided as soon as practicable
following the Substitution Date (and made one-time only), GSK will supply POZEN with Clinical Trial Materials in the Dosage Strength for MT 400 in a quantity requested by POZEN sufficient to complete the Development Plan for MT 400. GSK will supply
such Clinical Trial Materials to POZEN pursuant to the terms of Section 3.6, except that GSK will deliver to POZEN such Clinical Trial Materials as soon as practicable using Commercially Reasonable Efforts and POZEN will pay GSK for such Clinical
Trial Materials at a price equal to [***]%

 (plus the costs of freight from the GSK facility to the POZEN-designated facility) for the purpose of conducting clinical
trials; provided, however, GSK will not be obligated to supply such Clinical Trial Material for a Collaboration Product that has suffered a Product Failure. 
  
 (d) In the event a Product Failure has occurred, then GSK may exercise its right to substitute an Other Product as
the new Lead Product within 30 days following the date of such Product Failure in accordance with the terms and conditions of Section 3.3(a); provided, however, that in the event an Other Product is not designated as the Lead Product
by GSK within 90 days from the date of the Product Failure, then POZEN may terminate this Agreement upon the expiration of the foregoing period without further notice to GSK; further, provided, that in the event that any Other Product
is not designated as the Lead Product by the Parties under this Section 3.3, the rights and obligations of the Parties under Section 3.3(c) will not apply, unless otherwise agreed in writing by the Parties. 
  
 (e) In the event rights to MT 400 revert to POZEN as provided under
Section 3.3(c) as the result of a decision by the GSK Global Safety Board that GSK cannot continue development of MT 400 and an election by GSK to substitute an Other Product (in lieu of MT 400) as the new Lead Product, GSK will not make the
transfers, assignments or deliveries or take other actions described in Sections 3.3(c)(ii) and 3.3(c)(v) above and Section 3.3(f) below will not apply. 
  

(f) In connection with any supply or transfer of Clinical Trial Materials or commercial supply of MT 400 under this Section 3.3 and for so long
as GSK supplies any of the foregoing to POZEN or POZEN is using such Clinical Trial Materials or selling such commercial supply of MT 400, GSK will grant to POZEN rights of reference (and a letter of authorization to FDA to that effect) to any GSK
IND or NDA pertaining to sumatriptan. Upon the expiration of such right, POZEN will send written notice to such effect to the FDA. If POZEN elects to continue any ongoing studies using Sumatriptan or Clinical Trial Material supplied by GSK, GSK will
continue to support CMC aspects of the respective IND with appropriate documentation in order to allow completion of any such studies. The foregoing in no way is meant to confer any rights or create any implied licenses to POZEN to subsequently
Commercialize MT 400 using Sumatriptan or commercial supply prior to expiry of the GSK Sumatriptan Patents (absent a license from GSK or right to such supply, as otherwise provided for under this Agreement).  
  
 3.4 Development Activities. 
  
 (a) POZEN will be responsible for undertaking the POZEN Development
Activities and will use Commercially Reasonable Efforts to perform the POZEN Development Activities in accordance with the POZEN Development Timeline. The Joint Project Team will monitor each Party’s respective obligations and progress towards
achieving the goals set forth in the Development Plan. POZEN may outsource the performance of any part of the POZEN

 19 








 Development Activities subject to Section 14.1. If POZEN elects to outsource the performance of any part of the POZEN
Development Activities, POZEN will notify GSK in writing regarding the nature of such proposed activities. After receiving such notice, GSK may provide POZEN feedback regarding such activities. 
  
 (b) GSK will be responsible for undertaking the GSK Development
Activities and will use Commercially Reasonable Efforts to perform the GSK Development Activities in accordance with the Formulation Development Timeline. The Joint Project Team will be responsible for monitoring the achievement of the Formulation
Development Timeline. 
  
 (c) Promptly after the
Execution Date and subject to the terms of Article 11 below, GSK will disclose to POZEN [***] to the extent known by GSK. POZEN will limit access to such information to those employees (or legal counsel subject to confidentiality obligations no less
rigorous than those contained herein) that have a need to know. POZEN may reasonably request additional materials and information relating to the foregoing and will engage in an evaluation of the Formulation based upon the information disclosed by
GSK.  
  
 (d) POZEN may raise any concerns it may
have regarding the Formulation at the Joint Project Team meetings and the Parties will work in good faith to address such concerns. POZEN may request that the Joint Project Team develop a course of action to achieve the Formulation Development
Timeline if it determines that such timeline may be subject to delay for any reason. Promptly upon such request, the Parties will share information regarding the status of GSK’s development of the solid oral dose of the Formulation and the
Joint Project Team will consider whether alternative actions should be implemented by the Parties (including the cooperation between the Parties to pursue a parallel formulation effort) taking into account the scientific evidence then available and
the best interests in the timely development of MT 400 in accordance with the Development Plan.  
  
 (e) At any time after the Effective Date if GSK determines that it must acquire rights to any intellectual property Controlled by a Third Party in
order to practice the Formulation it will promptly send written notice to POZEN to that effect. GSK will use commercially reasonable efforts to negotiate rights to such Third Party technology that include the right to sublicense such technology to
POZEN as otherwise provided herein. If GSK is unable to secure such sublicense rights or if in order to secure such sublicense rights, the total consideration for acquiring such sublicense rights would be materially higher than if GSK did not
acquire such sublicense rights, GSK promptly will send written notice to POZEN to that effect. Within 30 days of receipt of such notice, POZEN may elect whether or not it wishes to pay such additional amounts for the inclusion of such sublicense
rights. If POZEN elects to pay such amounts it will reimburse GSK for such costs within 30 days of receipt of an invoice for such amounts. If POZEN elects not to pay such additional amounts or fails to give notice of its intent to do so within the
30 day period provided above, GSK may enter into such agreement without the inclusion of such sublicense rights. Failure to include such sublicense rights [***] under this Section 3.4(e) if [***] with such Third Party for the inclusion of such
rights.

 (f) GSK may outsource the performance of any part (but not all) of the GSK Development Activities.
If GSK elects to outsource the performance of any of the GSK Development Activities, it will notify POZEN in writing regarding the nature of such proposed activities. After receiving such notice, POZEN may provide GSK feedback regarding such
activities. 
  
 3.5 Regulatory. 
  
 (a) IND and NDA. In accordance with the provisions of
Section 6.1 below, POZEN will prepare and file, in its own name and at its own expense, the IND and NDA for the Lead Product, and any other regulatory filings in the Territory necessary to obtain NDA Approval for the Lead Product. GSK will assist
POZEN, with the preparation of any regulatory filings, including granting POZEN rights of reference (and a letter of authorization to FDA to that effect) to any GSK IND or NDA pertaining to sumatriptan for the sole and limited purpose of enabling
and supporting the FDA’s review of the NDA for the Lead Product. GSK also will (i) provide POZEN with data and reports resulting from the GSK Development Activities (including any activities regarding manufacturing scale-up and information
related to the Lead Product) and (ii) prepare the CMC portion of the NDA and IND as required for registration of the Lead Product in the Territory as described in the GSK Development Activities, including, without limitation, revisions to such
filings based upon any interactions with the FDA from time to time at POZEN’s request and as may be reasonably necessary to obtain approval of such regulatory filings. After Final Regulatory Approval is obtained for the Lead Product [***] as
provided in Section [***], ownership of the NDA and all other regulatory filings for the Lead Product in the Territory, will be assigned by POZEN to GSK at no additional charge to GSK. At GSK’s request POZEN will take such steps, including
submission of appropriate correspondence to FDA, as are necessary to effectuate the assignment.  
  
 (b) Additional Regulatory Filings. GSK will have the exclusive right to prepare and file, in its own name and at its expense, any
additional regulatory filings for the Collaboration Products in the Territory, including, without limitation, any filings relating to label expansions for any such Collaboration Product. 
  
 (c) Adverse Event Reporting. GSK will be responsible for all reporting of adverse events with respect to each
Collaboration Product to the Regulatory Authorities in the Territory and POZEN will be responsible for all reporting of adverse events with respect to any Products developed by POZEN in the Territory for sale outside the Territory in accordance with
the terms of this Agreement or other products developed or commercialized by POZEN outside the scope of this Agreement; provided, however, that until the NDA for the Lead Product is transferred to GSK, POZEN will be responsible for all
reporting of adverse events with respect

 21 








 to the Lead Product to the Regulatory Authorities in the Territory. To the extent either Party receives any information
regarding serious adverse drug events related to the use of a Product, whether such use is within or outside of the Territory, such Party will promptly provide the other Party with such information in accordance with the terms of a Safety Data
Exchange Agreement mutually acceptable to the Parties to be entered into within 60 days of the Effective Date. To the extent POZEN is required to report adverse events encountered with a Product in connection with POZEN’s activities inside or
outside the Territory, POZEN will be entitled to report such adverse events, but prior to doing so, will give GSK as much advance warning of such report as is reasonably possible, and POZEN will report such adverse events inside or outside the
Territory in a manner which is consistent with the reporting of adverse events for the Territory. 
  
 (d) Safety Concerns. GSK will provide notice to POZEN and the Joint Project Team promptly upon the taking of any action by an employee or
agent of GSK to seek review by the GSK Global Safety Board in respect of any proposed or on-going clinical study proposed to be conducted or conducted pursuant to this Agreement. Each Party will co-operate with the other Party in the preparation of
such review. GSK will provide to POZEN and the Joint Project Team copies of any submissions made to the GSK Global Safety Board and will use its good faith efforts to include a representative of POZEN in preparing any submissions to the GSK Global
Safety Board and allowing such representative to observe any related proceeding held by the GSK Global Safety Board where such Board will make any final determination in respect of the matters covered by this Section 3.5(d); provided such
attendance is in the discretion of the chairman. GSK will have the right to determine that a [***] pursuant to this Agreement [***] in accordance with this Section 3.5(d) [***] under 21 C.F.R. Section 312.32(c), as amended, or [***]. Any such
determination by the GSK Safety Board will be made in good faith using scientific and medical criteria and available information derived from pre-clinical and clinical studies conducted pursuant to this Agreement and will not include the
consideration of commercial factors. Promptly upon a request by GSK to [***] under this Section 3.5(d), [***], as applicable, such clinical study in a manner consistent with over-all patient safety and representatives of the Parties will immediately
meet to consider such determination. Within 45 days from such determination by the GSK Global Safety Board GSK may elect to substitute an Other Product (in lieu of a solid oral dose of MT 400 in the Formulation) as the new Lead Product pursuant to
Section 3.3; provided, however, that absent any such timely election, or waiver by POZEN to the contrary, GSK will be deemed to have terminated this Agreement under Section 12.3 immediately upon the expiration of the foregoing 45-day

rights of reference (and a letter of authorization to FDA to that effect) to any GSK IND or NDA pertaining to sumatriptan. Upon the expiration of such right, POZEN will send written notice to such effect to the FDA. If POZEN elects to continue any
ongoing studies using Sumatriptan or Clinical Trial Material supplied by GSK, GSK will continue to support CMC aspects of the respective IND with appropriate documentation in order to allow completion of any such studies. The foregoing in no way is
meant to confer any rights to POZEN to subsequently commercialize MT 400 using Sumatriptan or commercial supply prior to expiry of the GSK Sumatriptan Patents (absent a license from GSK or right to such supply, as otherwise provided for under this

the milestone payments will apply, and GSK will not be required to pay the milestone payment outlined in “4” under “Milestone Events—Lead Product” set forth in Section 7.2 until it has been achieved in accordance with the
provisions of said Section.

 (c) Product Launch. Within [***] following NDA Approval for the Lead Product [***], GSK
will notify POZEN in writing of [***], GSK will use Commercially Reasonable Efforts to initiate Commercial Launch of the Lead Product in the Territory as soon as commercially practicable after Final Regulatory Approval is granted, but in no event
later than [***] following such NDA Approval (excluding delays not within GSK’s control, if any, related to manufacturing issues or the requirements of the FDA), in accordance with the Product Launch Plan and Commercialization Plan. [***], GSK
will use its Commercially Reasonable Efforts in performing Commercialization activities with respect to a Product in accordance with Section 5.2 and the Product Launch Plan and Commercialization Plan. If [***] in accordance with Section [***] of
this Agreement [***], then POZEN will have the right to terminate this Agreement [***]. 
  
 (d) Significance of Non-diligence. GSK and POZEN acknowledge that the market potential of the Lead Product would be severely compromised by a significant delay in executing the Initial Development Plan,
Product Launch Plan and Commercialization Plan for the Lead Product and, therefore, GSK’s or POZEN’s failure to use Commercially Reasonable Efforts to adhere to the timelines set forth in any of the foregoing plans for the Lead Product
that results in any such significant delay will constitute a material breach of this Agreement.  
  
 (e) Special Meeting of Joint Project Team. If a Party believes that the other Party has failed to comply with its diligence obligations
under this Article 6 (a “Notifying Party”), then such Notifying Party may convene a special meeting of the Joint Project Team to discuss the matter (a “Special Meeting”) by written notice to the other Party (the
“Receiving Party”). Such notice may include a general statement of the areas of concern to the Notifying Party. The Special Meeting will be convened not later than thirty (30) days after such notice is given. At the Special Meeting,
the Joint Project Team will discuss the areas of concern to the Notifying Party and the additional actions (if any) the Receiving Party could take to address such concerns.  
  
 (f) Supplemental Plan. If, after a Special Meeting, the Notifying Party continues to believe that the
Receiving Party is not meeting its diligence obligations pursuant to this Article 6 or if the Notifying Party wishes to formalize the Receiving Party’s commitment to take such additional actions (if any) discussed in the Special Meeting, then
the Notifying Party may so notify the Receiving Party in writing. Within thirty (30) days after the date of any such notice, the Receiving Party will indicate in writing to the Notifying Party whether it agrees with the concerns of the Notifying
Party. If the Parties disagree, then each Party may invoke the dispute resolution mechanism described in Article 13. If the Receiving Party agrees that additional actions need to be taken, the Receiving Party will provide the Notifying Party with a
plan describing the actions that the Receiving Party proposes to take to meet such obligation. If the Notifying Party then notifies the Receiving Party in writing that the Notifying Party agrees that such plan describes actions sufficient to meet
such obligation, then such plan will be a “Supplemental Plan” and the Receiving Party will carry out the actions described in such plan.

 34 








 Each Supplemental Plan will include a specific timeline for the Receiving Party to take the steps described in such Plan.
If the Notifying Party disagrees with the Receiving Party as to the sufficiency of the actions described in such plan to meet such obligation, and the Parties are unable to resolve such disagreement within thirty (30) additional days, either Party
may invoke the dispute resolution mechanisms described in Article 13. No Supplemental Plan will be deemed to constitute an amendment to this Agreement. 
  
 (g) Availability of Other Remedies. If the Parties agree on a Supplemental Plan, then so long as the Receiving Party complies with
such Supplemental Plan, the Notifying Party will not have the right to pursue any other remedies it may have available to it at law or in equity for the Receiving Party’s failure to meet its obligations under Article 6 in areas specifically
addressed by the Supplemental Plan, as applicable. If the Notifying Party is of the opinion that the Receiving Party has failed to materially comply with any Supplemental Plan, then the Notifying Party will send a notice to the Receiving Party, and
each Party may invoke the dispute resolution mechanisms described in Article 13. 
  
 7. COMPENSATION. 
  
 7.1
Consideration. As partial consideration for the licenses granted to GSK by POZEN under the terms of this Agreement, GSK will pay to POZEN: 
  
 (a) a non-refundable, non-creditable license fee equal to [***] $[***] within five (5) days of the Effective Date. 
  
 (b) a non-refundable, non-creditable, payment in the amount of [***]
$[***] within thirty (30) days receipt of an invoice and notice from POZEN of the issuance of a United States Patent issuing from POZEN’s continuation patent application filed in the United States Patent and Trademark Office with USPTO
reference number 09/559,753 with one or more claims in such patent application that specifically claim [***]. 
  
 7.2 Development Milestones. As additional consideration for the licenses granted to GSK by POZEN under the terms of this Agreement, GSK will also
pay to POZEN the following non-refundable, non-creditable, one-time payments in the amounts set forth below [***] receipt of notice and an invoice from POZEN of the first occurrence of the events specified below: 
  

			
	 Milestone Events – Lead Product

	  	$[***]
		
	 2. NDA Approval of each Other Product that is not the Lead Product
	  	$[***]

  
 For the avoidance of doubt, in the
event that an Other Product becomes a Lead Product solely by the operation of Section 1.41(c), then GSK will make the milestone payments under the “Lead Product” heading with respect to such Other Product, except that GSK will not have the
obligation to make the milestone payments provided for above under the “Lead Product” heading for such Other Product if the particular milestone payment has already been paid in the course of the development of MT 400 or any other Lead
Product. 
  
 7.3 Commercial Milestones. As additional
consideration for the licenses granted to GSK by POZEN under the terms of this Agreement, GSK will pay to POZEN the following non-refundable, non-creditable, one-time payments in the amounts set forth below [***] of occurrence of the events related
to the Lead Product specified below: 
  

			
	 Milestone Event – Lead Product

	  	Milestone Payment Amount

 36 








 For the avoidance of doubt, if annual Net Sales of $[***] and $[***] are reached for the first time in the same calendar
year, the higher Milestone Payment, $[***], will be paid in that calendar year. The $[***] Milestone Payment will be paid in the first subsequent calendar year in which annual Net Sales of $[***] are achieved. In no single calendar year will both
commercial milestone payments described in this Section 7.3 be due and payable. 
  
 7.4 Royalties. Subject to the adjustments provided for Sections 7.5 and 7.7, GSK will pay to POZEN a percentage of annual Net Sales of Collaboration Products as determined below:

 7.5 Reduction Due to Generic Erosion. Generic Erosion for any Collaboration Product then-currently
Commercialized by GSK will be calculated on a calendar quarterly basis using reference data published by IMS Health, Scott-Levin or another industry-accepted source used by GSK at the time that such determination is made. If Generic Erosion for any
such Collaboration Product is documented for a particular calendar quarter, the reduced royalty set forth in Section 7.4 above will apply and be limited to each subsequent calendar quarter in which such Generic Erosion continues to exist, as
documented by GSK pursuant to this Section 7.5. 
  
 7.6 Royalty
Term. Royalties due under Section 7.4 above will be payable on a Collaboration Product-by-Collaboration Product basis commencing on the First Commercial Sale of a Collaboration Product until the later of: (a) the expiration of the last-to-expire
issued Patent within the POZEN Technology containing a Valid Claim covering such Collaboration Product in the Territory; or (b) [***] ([***]) years from the First Commercial Sale of such Collaboration Product in the Territory (the “Royalty
Payment Period”). For the convenience of the Parties, and in order to facilitate the payment of royalties in even installments and to reduce accounting and audit burdens of the Parties, the Parties have agreed to apply the same royalty rate
during the term of the Royalty Payment Period, rather than charging a higher royalty rate during the term when the Collaboration Products are covered by a Valid Claim, and a lower royalty rate after expiration of all Valid Claims. 
  
 7.7 Third Party Royalties. 
  
 (a) General. During the Term of this Agreement, GSK or its Affiliates
may from time to time obtain a license to practice any Third Party’s Patent rights (which also may include a license to related Know-How) in connection with GSK’s development or Commercialization of a Collaboration Product in the
Territory. In such event, GSK will be entitled to deduct, on a Collaboration Product-by-Collaboration Product basis, a portion of the royalties, milestones or other non-recurring licensing fees paid to a Third Party from milestone payments or
royalties in the case of [***] or from royalties in the case of [***], in each case otherwise due to POZEN hereunder only where (i) GSK has solely an intellectual property license arrangement with such Third Party relating to such Collaboration
Product (and not agreements for development or supply of such Collaboration Product that involve payments for goods or services in addition to the acquisition of intellectual property rights); and (ii) the royalty portion paid to such Third Party
pursuant to such license is payable on net sales of such Collaboration Product pursuant to a net sales definition that is generally in accordance with the definition of “Net Sales” provided for in this Agreement. Where the foregoing
conditions are satisfied, such royalties, milestones or other non-recurring licensing fees will be deemed a “Third Party Royalty” and in each case GSK may make such deductions from amounts due POZEN solely in accordance with the
following terms and conditions of this Section 7.7. GSK will provide to POZEN an executed copy of any license agreement between GSK and such Third Party pursuant to which GSK has obtained rights to such Third Party’s Patent. In the event that

  

 CONFIDENTIAL TREATMENT HAS BEEN GRANTED FOR THE REDACTED PORTIONS OF THE AGREEMENT THAT ARE MARKED WITH ASTERISKS
AND BRACKETS ([***]). A COMPLETE COPY OF THIS AGREEMENT, INCLUDING THE REDACTED PORTIONS, HAS BEEN SEPARATELY FILED WITH THE SECURITIES AND EXCHANGE COMMISSION. 
  
 38 








 the condition described in subsection (i) above is not satisfied with respect to a particular Third Party agreement, then
the Parties will in good faith determine the applicable amount of the Third Party Royalty that may be deducted pursuant to this Section; provided, the Parties agree that any amounts not attributable to intellectual property license rights
(such as development costs or the cost of goods) will be excluded from any Third Party Royalty otherwise applied to such agreement. 
  
 (b) Reduction Applicable at a [***] Percent or Lower Royalty Rate. 
  
 (i) MT 400. If the applicable royalty rate for MT 400 under Section 7.4 is less than or equal to [***]
percent ([***]%), then GSK may reduce the milestones or royalty amount payable to POZEN for MT 400 at the end of a particular calendar quarter by an amount equal to [***]% of any Third Party Royalty paid by GSK for such calendar quarter for any
Blocking Patent pertaining to MT 400 (such amount, the “POZEN MT 400 Portion”); provided, however, that such aggregate milestone and royalty reduction will not exceed [***] percent ([***]%) [***] for MT 400 during such
quarter (the “MT 400 Cap”) except in respect of an MT 400 Carry Forward Reduction (defined below). If the POZEN MT 400 Portion exceeds the MT 400 Cap for any calendar quarter, then GSK will be entitled to deduct such excess amount
(an “MT 400 Carry Forward Reduction”) from royalties or milestones payable to POZEN under Section 7.4 (if any) in respect of any Collaboration Product (other than MT 400) during such calendar quarter where the limitations on
GSK’s ability to deduct a Third Party Royalty for a Collaboration Product from amounts otherwise due POZEN as described in Section 7.7(b)(ii), Section 7.7(c) or Section 7.7(d), as applicable, have not been reached for such quarter. GSK will be
entitled to aggregate any MT 400 Carry Forward Reductions in a calendar year and carry forward such reductions during such calendar year in order to reduce amounts otherwise payable to POZEN as provided in the immediately preceding sentence. Any MT
400 Carry Forward Reduction not deducted by GSK from amounts otherwise payable to POZEN in accordance with this Section 7.7(b)(i) during a particular calendar year will expire and thereafter may not be deducted from amounts otherwise payable to
POZEN in a subsequent calendar year. 
  
 (ii) Other
Collaboration Products. If the applicable royalty rate for a Collaboration Product (other than MT 400) under Section 7.4 is less than or equal to [***] percent ([***]%), then GSK may reduce the milestones or royalty payable to POZEN for such
Collaboration Product for a particular calendar quarter by an amount equal to [***]% of any Third Party Royalty paid by GSK for such calendar quarter for any Blocking Patent pertaining to such Collaboration Product; provided, however,
that in no event will such aggregate milestone and royalty reduction exceed [***] percent ([***]%) [***] for such Collaboration Product for such calendar quarter. 
  
 (iii) No Reduction for Commercially Necessary Patents. For the avoidance of doubt, GSK will not be entitled
to reduce the royalty payable to POZEN under

 Section 7.4 for a Collaboration Product for the payment by GSK of any Third Party Royalty for any Commercially Necessary
Patent in the event that the applicable royalty rate under Section 7.4 is less than or equal to [***] percent ([***]%). 
  
 (c) Reduction Applicable at a Royalty Rate in Excess of [***] Percent. If the applicable royalty rate for a Collaboration Product under
Section 7.4 is greater than [***] percent ([***]%), then GSK may reduce the royalty amount (and milestones in the case of Blocking Patents pertaining to such Collaboration Product) payable to POZEN for a particular calendar quarter for such
Collaboration Product by: 
  
 (i) an amount equal to
[***]% of the Third Party Royalty paid by GSK for such calendar quarter for any such Blocking Patent; and 
  
 (ii) an amount equal to [***]% of the Third Party Royalty paid by GSK for such calendar quarter for any Commercially Necessary Patent pertaining
to such Collaboration Product; 
  
 provided, however, that (A) the
aggregate reduction to the milestones and royalty payments made pursuant to the operation of Section 7.7(c)(i) will not exceed an amount equal to [***]% [***] under Section [***] or Section [***], as applicable, for such quarter using the
then-applicable royalty rate (without regard to application of this Section 7.7); (B) the aggregate reduction to the royalty payments made pursuant to the operation of Section 7.7(c)(ii) will not exceed an amount equal to [***]% [***] under Section
[***] (without regard to application of this Section 7.7); and (C) the aggregate reduction to the milestones (in the case of Blocking Patents) and royalty payments determined by the sum of the amount determined under Section 7.7(c)(i) and the amount
determined under Section 7.7(c)(ii) will not exceed an amount equal to [***]% [***] under Section [***] or Section [***], as applicable, for such quarter using the then-applicable royalty rate (without regard to application of this Section 7.7).

  
 (d) Reduction of a Non-Recurring Third Party
Royalty. In the event GSK pays a milestone or other non-recurring licensing fee that is a Third Party Royalty in respect of a Blocking Patent for a particular Collaboration Product (a “Third Party Milestone Payment”) prior to
the date that royalties are otherwise payable to POZEN hereunder for such Collaboration Product, GSK may reduce the next subsequent milestone or royalty payment, as the case may be, payable to POZEN in respect of such Collaboration Product by the
amount equal to [***]% [***]; provided, however, that the aggregate reduction prior to the First Commercial Sale of such Collaboration Product determined in accordance with the preceding clause will not exceed an amount equal to [***]%
[***] (without regard to the application of this Section 7.7(d)); provided, further, that any Third Party Milestone Payment paid by GSK and not otherwise deducted by GSK from amounts payable to POZEN due to the limitations imposed by
the foregoing clause or due to the fact that the Third Party Milestone Payment was paid by GSK after the First Commercial Sale of such Collaboration Product may be carried forward by GSK

 (i) during the period [***] the First Commercial Sale, to reduce in accordance with this Section 7.7(d) [***] payable to
POZEN for the applicable Collaboration Product, or (ii) during the period [***] First Commercial Sale, to reduce in accordance with Sections 7.7(b) and 7.7(c) any subsequent milestone or royalty payment(s) payable to POZEN for the applicable
Collaboration Product. 
  
 7.8 Royalty Payments and Reports.
During the Royalty Payment Period, GSK will pay all royalty payments due to POZEN under Section 7.4 within forty five (45) days of the end of each calendar quarter during which the Net Sales in respect of which such amounts are due were made.
Each payment of royalties owing to POZEN will be accompanied by a written statement of [***], a copy of which will be provided to POZEN within 25 days of the end of each calendar quarter, showing (a) the amount [***] of Collaboration Products and
(b) the amount of royalties due on such sales. If any payment reduction is claimed by GSK under this Agreement from the full royalty rates set forth in Section 7.4, then the report will set forth in detail the claimed reduction and the related
facts. 
  
 7.9 Payment Method. All payments due to POZEN
pursuant to this Agreement will be made in United States dollars by wire transfer in immediately available funds to an account designated by POZEN. Any amounts not paid by GSK when due under this Agreement will be subject to interest from and
including the date payment is due through and including the date upon which GSK has made a wire transfer of immediately available funds into an account designated by POZEN at a rate equal to the sum of [***] percent ([***]%) plus the annual prime
rate of interest quoted in the Money Rates section of The Wall Street Journal, Eastern Edition, for the date on which payment was due, calculated daily on the basis of a 365-day year, or similar reputable data source, or, if lower, the
highest rate permitted under applicable law. The Parties agree that this provision, unless otherwise provided, will not apply to payments that are the result of a subsequent adjustment of an estimated payment, including rebates, adjustments, returns
or true-ups. 
  
 7.10 Taxes. POZEN will be responsible for
any and all taxes levied on account of amounts it receives under this Agreement. If GSK or any Affiliate or other delegee of GSK (each, a “GSK Payor”) is required by law, rule or regulation to withhold taxes from such types of
payments due POZEN hereunder, GSK will (a) deduct those taxes from the remittable amount, (b) pay the taxes to the proper taxing authority and (c) send evidence of the obligation together with proof of payment to POZEN within thirty (30) business
days following that payment. If a GSK Payor is required to withhold any taxes or other payments due a proper taxing authority from payments made to POZEN under this Agreement, then GSK will pay to POZEN an amount equal to the amount GSK owes to the
relevant tax authority such that the net amount paid to POZEN will equal that otherwise payable to POZEN had such withholding not been made; provided always that if POZEN is able to obtain credit for any taxes withheld (“Creditable
Taxes”) against any liability to tax either in the year in which the receipt is taxable

 41 








 or any other year, POZEN will reimburse to GSK an amount equivalent to the Creditable Taxes. POZEN will provide GSK with
such reasonable evidence as GSK may reasonably request to determine whether the taxes are creditable against taxes payable by POZEN. 
  
 7.11 Audits. During the Term and for a period of [***] thereafter, at the request and expense of POZEN, GSK will permit an independent, certified
public accountant of nationally recognized standing appointed by POZEN (that has not otherwise been engaged by POZEN), and reasonably acceptable to GSK, at reasonable times and upon reasonable notice, but in no case no more than once per calendar
year thereafter to examine such records as may be necessary for the sole purpose of verifying the calculation and reporting of [***] and the correctness of any royalty payment made under this Agreement for any period within the preceding [***].
Results of any such examination will be made available to both POZEN and GSK. The independent, certified public accountant will disclose to POZEN only the royalty amounts that the independent auditor believes to be due and payable hereunder to POZEN
and will disclose no other information revealed in such audit. Any and all records examined by such independent accountant will be deemed GSK’s Confidential Information which may not be disclosed by such independent, certified public accountant
to any Third Party. If, as a result of any inspection of the books and records of GSK, it is shown that GSK’s payments under this Agreement were (i) less than the amount which should have been paid, then GSK will make all payments required to
be made to eliminate any discrepancy revealed by said inspection within thirty (30) days; or (ii) more than the amount which should have been paid, then GSK will be entitled to reduce subsequent royalty payments to POZEN by such excess amount
(provided that such reduction will not reduce the total amount of the subsequent royalty payment to POZEN by more than [***]%) until such time as such amounts have been fully recovered. POZEN will pay for such audits, except that if the royalty
payments made by GSK were less than [***] percent ([***]%) of the amounts that should have been paid during the period in question, GSK will pay the costs of the audit. 
  
 8. INVENTIONS AND PATENTS. 
  
 8.1 Ownership of Inventions. 
  
 (a) Inventorship of any inventions or discoveries, that in the case
of patentable inventions, were conceived and reduced to practice, and in the case of non-patentable inventions, were made or developed, in the course of performing activities under this Agreement (“Inventions”), will be determined
in accordance with the rules of inventorship under United States patent laws with respect to patentable Inventions, and in accordance with applicable U.S. federal or state law with respect to non-patentable invention, as set forth in further detail
in Section 8.1(b) through (d). 
  
 (b) POZEN will own all
right, title and interest in and to POZEN Inventions, and all intellectual property rights appurtenant thereto.

 42 








 (c) GSK will own all right, title and interest in and to GSK Inventions, and all intellectual
property rights appurtenant thereto. 
  
 (d) All right,
title and interest in and to Inventions made and reduced to practice during the Term jointly by employees or contractors of each Party (“Joint Inventions”), and all intellectual property rights appurtenant thereto, will be owned
jointly by the Parties. Except to the extent either Party is restricted by the licenses granted to the other Party and covenants contained herein, each Party will be entitled to practice and sublicense Joint Inventions without restriction or consent
of the other or an obligation to account to the other Party, and each Party hereby waives any right it may have under the laws of any jurisdiction to require any such consent or accounting. 
  
 8.2 Obligation to Inform. POZEN will promptly disclose to GSK all
POZEN Inventions that arise during the Term. GSK will promptly disclose to POZEN all GSK Inventions that arise during the Term. Information provided by GSK or POZEN to the other with respect to such Inventions will be in reasonable detail but in no
circumstance less than would be sufficient to permit an understanding of the nature of the Inventions by a practitioner reasonably skilled in the relevant technical or scientific area. 
  
 8.3 Patent Prosecution and Maintenance. 
  
 (a) POZEN Patents. POZEN will retain control over the prosecution and maintenance of all POZEN Patents,
including those identified on Exhibit A, at its expense, using patent counsel of its choice. In connection with the prosecution of POZEN Patents, POZEN will grant to GSK the right to: (i) review POZEN’s pending patent applications and
related proceedings, and to make recommendations to POZEN regarding the prosecution of such patent applications; (ii) receive such applications and other documentation at such time as to allow a reasonable period for review thereof prior to any
applicable deadline for filing or responding; and (iii) the right to propose amendments of any such patent application to include claims or arguments. 
  
 (b) Other Patents. Each Party will be responsible for, and will bear the expense of, the preparation, filing, prosecution and maintenance
(including without limitation conducting or participating in interferences or oppositions) of its solely-owned Patents at its sole expense. Each Party will provide the other with periodic updates with respect to Patent applications or other
submissions filed or made or to be filed or made by such Party covering the Product or any of the Inventions described in Section 8.1, and will respond to the other Party’s questions concerning such submissions reasonably promptly thereafter.
The Parties will confer and cooperate in good faith with respect to the prosecution and maintenance of Patents that claim Joint Inventions (“Joint Patents”). Each Party hereby agrees to take all actions and execute and deliver all
documents reasonably necessary to file or prosecute Joint Patents.

 8.4 Infringement of Patents by Third Parties. 
  
 (a) Notification. If either Party learns of any actual or
threatened infringement in the Territory by a Third Party of a POZEN Patent or Joint Patent, including infringement arising from the manufacture, use, or sale of a product competitive with a Collaboration Product that is being developed or
Commercialized by GSK (“Competitive Product Infringement”), such Party will promptly notify the other Party and will provide such other Party with all available evidence of such infringement. In addition, POZEN will promptly notify
GSK upon learning that the manufacture, use or sale of MT 400 or the practice of any inventions covered by one or more claims included in the POZEN Patents or the use of any POZEN Know-How licensed hereunder may infringe any rights of a Third Party.
Each Party will use its commercially reasonable efforts in cooperating with each other to terminate such infringement without litigation. 
  
 (b) Infringement of POZEN Patents and Joint Patents. GSK will have the right, but not the obligation, to bring, at its own expense and in
its sole control, an appropriate action against a Third Party engaged in any Competitive Product Infringement of a POZEN Patent or Joint Patent. If GSK does not bring such action within ninety (90) days of notification thereof between the Parties
pursuant to Section 8.4(a), POZEN will have the right, but not the obligation, to bring at POZEN’s expense and in its sole control, such appropriate action. POZEN will have the right, but not the obligation, to bring, at its own expense and in
its sole control, an appropriate action against a Third Party engaged in any infringement of a POZEN Patent that is not a Competitive Product Infringement. The Party not bringing an action under this Section 8.4(b) will be entitled to separate
representation in such matter by counsel of its own choice and at its own expense, and will cooperate fully with the Party bringing such action. 
  
 (c) Joint Patents. With respect to Third Party infringement of Joint Patents that is not a Competitive Product Infringement, the Parties
will confer and take such action, and allocate expenses and recoveries, in such manner as they will agree. 
  
 (d) Settlement; Allocation of Proceeds. Neither Party will settle a claim brought under this Section 8.4 involving a POZEN Patent or Joint
Patent that would limit or restrict the ability of GSK to sell a Product in the Territory, without the prior written consent of GSK (which consent will not be unreasonably withheld or delayed). GSK will not, without the prior written consent of
POZEN, settle any claim brought under this Section 8.4 involving POZEN Patents or Joint Patents that would (i) limit or restrict POZEN’s ability to sell POZEN’s products outside the Territory, (ii) permit a Third Party to sell POZEN’s
other products or products that infringe POZEN Patents, or (iii) result in an admission of invalidity or unenforceability of any POZEN Patent. If either Party recovers monetary damages from a Third Party in an action brought under this Section 8.4,
whether such damages result from the

 infringement of a POZEN Patent or Joint Patent, such recovery will be allocated first to the reimbursement of any
expenses incurred by the Parties in the litigation under this Section 8.4, and any remaining amounts will be divided between the Parties as follows: (a) the portion of any such remaining amounts that represents [***]; (b) the portion of any such
remaining amounts that represents [***]; and (c) the portion of any such remaining amounts that represents [***] percent ([***]%) [***] percent ([***]%) [***] unless GSK and POZEN have agreed in writing to a different allocation. 
  
 8.5 Third Party Challenges. If a POZEN Patent becomes the subject of
any proceeding commenced by a Third Party in connection with an opposition, reexamination request, action for declaratory judgment, nullity action, interference or other attack upon the validity, title or enforceability thereof, then GSK will have
the primary right, but not the obligation, to control such defense at its sole cost. GSK will permit POZEN to participate in the proceeding to the extent permissible under law, and to be represented by its own counsel in such proceeding at its
expense. If GSK elects not to defend against such action, it will notify POZEN thereof in writing without delay and not less than 30 days prior to any deadline for the initial response or other initial filing in any such proceeding, and POZEN will
then have the right to assume defense of such Third Party action at its own expense. If POZEN controls such action, it will not enter into any settlement or other voluntary final disposition of a defense under this Section 8.5 relating to a POZEN
Patent if the rights and privileges of GSK under this Agreement would be materially impaired thereby without the prior consent of GSK, such consent not to be unreasonably withheld or delayed. If GSK controls such action, it will not enter into any
settlement or other voluntary final disposition of a defense under this Section 8.5 relating to a POZEN Patent without the prior written consent of POZEN, such consent not to be unreasonably withheld or delayed. The control of any enforcement
proceeding brought in connection with a Third-Party challenge and the allocation of any recovery arising from such an enforcement action will be subject to Section 8.4(d).  
  
 8.6 Defense of Third Party Claims. 
  
 (a) Notice. If a Collaboration Product becomes the subject of a Third Party claim of patent infringement relating to
the manufacture, use, sale, offer for sale or importation of such Collaboration Product in the Territory, the Party first having notice of the claim will promptly notify the other Party, and the Parties will promptly meet to consider the claim and
the appropriate course of action. 
  
 (b) Defense and
Settlement. GSK will have the right, at its expense, to control the defense and settlement of any claim of patent infringement relating to its manufacture, use, sale, offer for sale or importation of a Collaboration Product in the Territory;
provided, however, that POZEN will have the right, at its sole discretion, to participate in any such resolution and to be represented by counsel of its own choice at its own expense. Subject to

 45 








 Section 7.7 above, if such infringement claim impinges on the freedom to operate under a POZEN Patent, GSK and POZEN will
discuss and agree on the scope of any license to be sought in connection with the settlement of such claim, taking into account the potential need of POZEN for a license broader than would be necessary for the Collaboration Product alone (and
subject to POZEN assuming the cost of such license to the extent it is broader than required by GSK); provided, that no settlement will be entered into without the written consent of POZEN if such settlement would restrict the claims in or
invalidate or make unenforceable in whole or in part any of the POZEN Patents. 
  
 8.7 Patent Marking. Any Collaboration Product marketed and sold by GSK under this Agreement will be marked with appropriate patent numbers or indicia as permitted by law, to the extent such markings have value
as notice against infringers of Patents in the Territory. 
  
 8.8 Patent Term Extensions. 
  
 (a) The
Parties will use reasonable efforts to obtain all available extensions of POZEN Patents and Joint Patents (including those available under 35 U.S.C. Section 156 et seq. (the “Hatch-Waxman Act”)) in the Territory. The Parties will
cooperate with each other in gaining Patent term restorations and extensions for POZEN Patents and Joint Patents in the Territory. The Parties will notify each other of the issuance of each Patent included within the POZEN Patents or Joint Patents
where extension is possible, giving the date of issue and Patent number for each such patent. 
  
 (b) The Party first eligible to seek patent term restoration or extension of any such POZEN Patent or Joint Patent will have the right to do so; provided, that if the first Party has an option to extend the
patent term for only one of several Patents, the first Party will consult with the other Party before making such election. If more than one POZEN Patent or Joint Patent is eligible for extension or patent term restoration, the Parties will agree
upon a strategy that will maximize patent protection for the Collaboration Products. 
  
 (c) All filings for such extensions of POZEN Patents will be made by POZEN, and all filings for such extensions of a Joint Patent will be made by the Party which prosecuted such Joint Patent; provided,
that in the event that a Party elects not to file for an extension of a Patent which it prosecuted, such Party will (i) promptly inform the other Party of its intention not to file and (ii) file for such extension on the other Party’s behalf,
if so instructed, or, in the case of a Joint Patent, grant to the other Party the right to file such extension and cooperate in such filing. The Party which is the sponsor of record of the NDA, at the time that applications for extension are
submitted, will execute such authorizations and other documents and take such other actions as may be reasonably requested by the other Party to obtain such extensions, including designating the other Party as its agent for such purpose as provided
in the Hatch-Waxman Act.

 46 








 (d) Any such extension of a POZEN Patent or a Joint Patent will be included within the definition
of POZEN Patents or Joint Patents, respectively.  
  
 8.9 Patent Certifications. 
  
 (a) Each
will immediately give notice to the other Party of any notice it receives of certification filed under the Hatch-Waxman Act claiming that any of the POZEN Patents is invalid, unenforceable or that any infringement will not arise from the
manufacture, use or sale of a Collaboration Product by a Third Party. If GSK decides not to bring infringement proceedings against the entity making such a certification with respect to any such POZEN Patents, GSK will give notice to POZEN of its
decision not to bring suit within ten (10) days after receipt of notice of such certification (or, if the time period permitted by law is less than twenty (20) days, within half of the time period permitted by law for GSK to commence such action).
POZEN may then, but is not required to, bring suit against the Third Party that filed the certification. Any suit by either Party may be in the name of either or both Parties, as may be required by law. For this purpose, the Party not bringing suit
will execute such legal papers necessary for the prosecution of such suit as may be reasonably requested by the Party bringing suit. 
  
 (b) To the extent required by law or permitted by law, GSK and POZEN will use commercially reasonable efforts to promptly list and maintain with
the applicable regulatory authorities during the term of this Agreement correct and complete listings of applicable Patents for any Collaboration Product then being commercialized by GSK, including all so called “Orange Book” listings
required under the Hatch-Waxman Act. Promptly after the Effective Date, POZEN and GSK will meet to discuss the Parties’ efforts under this Section 8.9(b). The Parties agree to co-operate on a listing strategy that maximizes the long term
intellectual property protection for Patents claiming the Products; provided, however, POZEN will retain final decision making authority as to the listing of the POZEN Patents. 
  
 8.10 Consequence of Patent Challenge. If GSK or its Affiliates
challenge the validity or enforceability of any of the POZEN Patents by any opposition, reexamination request, action for declaratory judgment, nullity action, interference or other attack upon the validity, title or enforceability thereof before
any governmental agency, court or other similar adjudicative forum (any such proceeding, a “Patent Challenge”), such Patent Challenge will be deemed to be a material breach of this Agreement and POZEN will have the right to
terminate this Agreement as provided in Section 12.2 or to terminate all licenses granted under any of the POZEN Patents subject to such Patent Challenge. If POZEN or its Affiliates challenge the validity or enforceability of any of the GSK Patents
by any Patent Challenge, such Patent Challenge will be deemed to be a material breach of this Agreement and GSK will have the right to terminate this Agreement as provided in Section 12.2 or to terminate all licenses granted under any of the GSK
Patents subject to such Patent Challenge.

 9.6 Consequential Damages. IN NO EVENT WILL EITHER PARTY OR THEIR AFFILIATES BE LIABLE FOR SPECIAL,
INDIRECT, INCIDENTAL, PUNITIVE, TREBLE OR CONSEQUENTIAL DAMAGES, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER LEGAL THEORY; PROVIDED, HOWEVER, THAT THIS LIMITATION WILL NOT LIMIT THE INDEMNIFICATION OBLIGATION OF SUCH PARTY UNDER THE
PROVISIONS OF SECTION 10 FOR SUCH DAMAGES CLAIMED BY A THIRD PARTY OR A PARTY’S LIABILITY FOR BREACH OF ITS OBLIGATIONS UNDER SECTION 11. 
  

	10.	INDEMNIFICATION.  

  
 10.1 Indemnification by GSK. GSK will indemnify, defend and hold harmless POZEN and its Affiliates, and their respective directors, officers,
employees and agents (the “POZEN Indemnitees”) from and against any liabilities, damages, costs or expenses, including reasonable attorneys’ fees and expenses (collectively, “Liabilities”), arising from any
claim, lawsuit or other action by a Third Party (“Claim”) to the extent resulting directly or indirectly from: (a) a breach by GSK of any of GSK’s representations, warranties, covenants or obligations contained within this
Agreement; (b) the development, manufacture, use, sale, offer for sale, and importation of Collaboration Products in the Territory by GSK or its Affiliates after the Effective Date; or (c) GSK’s gross negligence or intentional misconduct in its
conduct of its responsibilities pursuant to this Agreement. 
  
 10.2 Indemnification by POZEN. POZEN will indemnify, defend and hold harmless GSK and its Affiliates, and their respective directors, officers, employees and agents (the “GSK Indemnitees”) from and against all
Liabilities arising from any Claim to the extent resulting directly or indirectly from: (a) a breach by POZEN of any of POZEN’s representations, warranties, covenants or obligations contained within this Agreement; (b) the development and
manufacture of MT 400 by POZEN or its Affiliates prior to the Effective Date; (c) the development, manufacture, sale, offer for sale, and importation of the Products by POZEN or its Affiliates or any of its sublicensees after the Effective Date; or
(d) POZEN’s gross negligence or intentional misconduct in its conduct of its responsibilities pursuant to this Agreement. 
  
 10.3 Procedure. A Party seeking to claim indemnification under Section 10.1 or 10.2 hereof (the “Indemnitee”) will provide the
other Party (the “Indemnitor”) with prompt notice of the Claim giving rise to the obligation to Indemnify hereunder and the exclusive ability to defend or settle such Claim; provided, however, that the Indemnitor will
not enter into any settlement for damages other than monetary damages without the Indemnitee’s written consent, such consent not to be unreasonably withheld. The Indemnitee will reasonably cooperate with the Indemnitor at the Indemnitor’s
expense in the defense of the Claims that have been tendered to the Indemnitor. In addition, the Indemnitee will have the right to participate, at its own expense and with counsel of its choice, in the defense of any Claim the defense of which has
been assumed by the Indemnitor. If the Parties cannot agree as to the application of Sections

 10.1 and 10.2 to a particular Claim, then each Party may conduct its own defense of such Claim and reserves the right to
seek indemnity from the other Party upon the resolution of the underlying Claim, notwithstanding the provisions of this Section 10.3 requiring the Indemnitee to tender defense to the Indemnitor. 
  
 10.4 Insurance. Each Party will maintain commercially reasonable
insurance coverage commensurate with its obligations under this Agreement. It is understood that such insurance held by either Party will not be construed to create a limit of either Party’s liability with respect to its indemnification
obligations under this Article 10. If POZEN elects to exercise its Co-Promotion Option, the parties will provide for appropriate insurance provisions in the Co-Promotion Agreement. 
  

	11.	CONFIDENTIALITY. 

  
 11.1 Confidential Information. All information: (a) communicated by one Party to the other Party pursuant to this Agreement, the Letter Agreement
or the Confidential Disclosure Agreement executed by and between the Parties dated [***] (the “CDA”); and (b) identified by such communicating Party as confidential, or that the other Party has reason to believe is confidential,
will be deemed “Confidential Information” and subject to the terms of this Agreement. For the avoidance of doubt, nothing in this Agreement will amend, modify or terminate the obligations of the Parties under the CDA. 
  
 11.2 Treatment of Confidential Information. The Parties agree that
from and after the Effective Date and for [***] after expiration or termination of this Agreement 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) not disclose such Confidential Information to Third Parties without the prior written consent of the other Party, other than to its Affiliates, sublicensees, collaborators or any consultants as
necessary to the performance of or otherwise permitted by this Agreement, provided that any such disclosure be under confidentiality agreements with provisions at least as restrictive as those contained in this Article 11; and (c) not use
such Confidential Information for purposes other than those authorized expressly herein, including, without limitation, the right to grant sublicenses or authorize the grant of sublicenses. 
  
 11.3 Exceptions. The non-use and non-disclosure obligations set forth
in this Article 11 will not apply to information disclosed by a Party for which the receiving Party can show by competent proof: 
  
 (a) at the time of disclosure is in the public domain or thereafter becomes part of the public domain through no fault of the receiving Party;

  
 (b) was in the receiving Party’s possession prior
to the time of disclosure by the disclosing Party;

 (c) is independently made available to the receiving Party by a Third Party without violation of a
confidential relationship with the disclosing Party; or 
  
 (d)
was independently developed by the receiving Party without the use of or reference to any Confidential Information of the disclosing Party. 
  
 11.4 Authorized Disclosure. Notwithstanding any other provision of this Agreement, each Party may disclose Confidential Information of the other
Party: 
  
 (a) to the extent and to the persons and
entities required by an applicable governmental law, rule or regulation or court order; 
  
 (b) to the extent and to the persons and entities required by rules of the National Association of Securities Dealers; or 
  

(c) as necessary to prosecute or defend litigation or otherwise establish rights pursuant to procedures described in this Agreement, enforce
obligations or conduct the activities contemplated under this Agreement, but only to the extent that any such disclosure is necessary for such purposes. 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. 
  
 The Party required to disclose Confidential Information under this Section 11.4 will first give prompt notice to the other Party hereto to enable it to seek any available
exemptions from or limitations on such disclosure requirement and will reasonably cooperate in such efforts by the other Party.

 11.5 Terms of Agreement. The material terms of this Agreement will be the Confidential Information
of each Party subject to the special authorized disclosure provisions set forth below in this Section 11.5 (in lieu of the authorized disclosure provisions set forth in Section 11.4, to the extent of any conflict). The Parties acknowledge that
either Party may be obligated to file a copy of this Agreement with the U.S. Securities and Exchange Commission (the “SEC”) with its next quarterly report on Form 10-Q, annual report on Form 10-K or current report on Form 8-K or
with any registration statement filed with the SEC pursuant to the Securities Act of 1933, as amended. Each Party will be entitled to make any such required filing; provided that it requests confidential treatment of the more sensitive terms hereof
to the extent such confidential treatment is reasonably available to the filing Party under the circumstances then prevailing. In the event of any such filing, the filing Party will provide the non-filing Party with an advance copy of the Agreement
marked to show provisions for which the filing Party intends to seek confidential treatment and will reasonably consider the non-filing Party’s timely comments thereon. A Party may disclose the terms of this Agreement in confidence to its
financial and legal advisors and consultants or to potential investors in or acquirers of the stock or assets of such Party. 
  
 11.6 Publicity and Publications. 
  
 (a) General. Subject to the terms of this Section 11.6, if either Party desires to make a public announcement, presentation or statement concerning
(i) this Agreement or the terms hereof (including data or the development status of a Collaboration Product) or (ii) results arising from activities conducted pursuant to this Agreement concerning Collaboration Products (each, a “Proposed
Presentation”) such Party will provide the text of the Proposed Presentation in accordance with Section 11.6(c) below. A Party will not be required to seek the permission of the other Party to repeat in a Proposed Presentation any
information that has already been disclosed in an announcement, presentation or statement reviewed and approved by the other Party pursuant to this Section 11.6. 
  
 (b) POZEN Product Disclosures. POZEN also agrees to submit to GSK in accordance with the procedures described in
Section 11.6(c) any publication or presentation of results concerning any Product being developed by POZEN for sale outside the Territory that is the same combination of active ingredients as a Collaboration Product. POZEN will retain final decision
making authority under the terms of Section 11.6(c) with regard to such presentation or publication proposed to be disclosed by POZEN. This Section 11.6(b) will no longer apply to POZEN (and in no event will apply to any Third Party licensee of
POZEN) with respect to any Product from and after the date POZEN has entered into a definitive development or Commercialization arrangement for such Product with a Third Party for development or Commercialization of such Product outside the
Territory. For the avoidance of doubt, this Section 11.6(b) will in no way limit or otherwise restrict POZEN from making a public announcement, presentation or statement concerning activities outside the scope of this Agreement, except as expressly
provided for in this Section 11.6(b) and Section 11.6(d) below.

 54 








 (c) Procedures. 
  
 (i) The text of any Proposed Presentation will be presented in writing in the English language to the other Party
for review and comment reasonably prior to the time the presentation or publication is proposed for submission to any Third Party. Promptly after its receipt of such presentation or publication and reasonably prior to the time 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. 
  
 (ii) If a reasonable objection is
raised, including, for example, that the contents of the Proposed Presentation contain patentable subject matter for which patent protection should be sought, or that the Proposed Presentation discloses Confidential Information of the other Party,
then submission of the Proposed Presentation will be delayed, unless and until such time as consent to submission of the presentation or publication is given (such consent not to be unreasonably withheld or delayed) or except as otherwise provided
in subsection (iii) below or Section 11.6(b) above. Each Party will be acknowledged on any Proposed Presentation by the other Party in accordance with generally accepted rules of authorship. 
  
 (iii) Prior to the date that POZEN transfers to GSK the NDA for a
particular Collaboration Product, POZEN will retain final decision making authority under the terms of Section 11.6(c) with regard to Proposed Presentations relating to such Collaboration Product to be made by GSK pursuant to this Section 11.6(c)
and GSK will retain final decision making authority under the terms of Section 11.6(c) with regard to Proposed Presentations relating to such Collaboration Product to be made by POZEN pursuant to this Section 11.6(c). From and after the date that
POZEN has transferred to GSK the NDA for a particular Collaboration Product and for so long as GSK holds the NDA for such Collaboration Product, GSK will retain final decision making authority under the terms of Section 11.6(c) with regard to
Proposed Presentations relating to such Collaboration Product proposed to be made by either Party. Subject to the terms of Section 11.6(c), GSK may pursue a public relations campaign as part of its Commercialization efforts of the Lead Product prior
to the transfer of the NDA for such Lead Product with the prior consent of POZEN and, thereafter following such transfer, without the prior consent of POZEN. 
  
 (d) Notwithstanding anything in this Section 11.6 to the contrary, this Section 11.6 will not apply to or limit any disclosure of information
authorized under Section 11.4 or Section 11.5, in each case made in accordance with the terms thereof, or permit disclosures that are otherwise restricted by the provisions of Article 11.

 11.8 Return of Confidential Information. Promptly following the termination of this Agreement by
either Party or the expiration of the Term, each Party hereto and its Affiliates will use commercially reasonable efforts to return all Confidential Information of the other Party in its possession to the other Party and will certify to that effect
in writing upon the request of 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 laboratory notebooks; and (c) any portion of the
Confidential Information of the other Party which a Party is required by applicable law to retain. Further, POZEN will have the right to retain GSK Confidential Information transferred to POZEN pursuant to Section 3.3 or Section 12.4 to the extent
reasonably necessary, and solely, for exercising the rights granted in Section 3.3 and Section 12.4, respectively. Any Confidential Information of GSK relating to a Lead Product or Collaboration Product, as the case may be (the rights to which
revert to POZEN pursuant to Section 3.3 or Section 12.4) will be deemed Confidential Information of POZEN as well as GSK as of the Substitution Date or date of termination, respectively.

 (b) Failure to Cure. If the breaching Party fails to cure such breach as provided for in
Section 12.2(a) within the Cure Period (or for such period provided for in any plan provided pursuant to Section 12.2(a)), or fails to use commercial reasonable efforts to carry out such plan to cure the breach), then the non-breaching Party may
terminate this Agreement in its entirety upon written notice. 
  
 12.3 Permissive Termination by GSK. GSK may terminate this Agreement in its entirety at any time upon ninety (90) days written notice to POZEN for any reason or no reason. 
  
 12.4 Effect of Termination. 
  

(a) Termination By POZEN or by GSK for Convenience. If POZEN terminates this Agreement pursuant to either Section 3.3(d), Section 6.1(b),
Section 6.2 or Section 12.2, or GSK terminates this Agreement pursuant to Section 12.3, then all licenses granted to GSK by POZEN under this Agreement will terminate, and all rights therein will revert to POZEN. Upon such termination, the following
provisions apply: 
  
 (i) GSK will promptly assign
and surrender to POZEN all Final Regulatory Approvals, if any, for all Collaboration Products and all pending regulatory filings for all Collaboration Products. GSK will take all actions reasonably necessary to timely effect the transfer of each
such item to POZEN, including, without limitation, by making such filings as may be required with Regulatory Authorities and other governmental authorities in the Territory that may be necessary to record such assignment or effect such transfer or,
at POZEN’s request, complete any pending regulatory filings in respect of all Collaboration Products. 
  
 (ii) GSK will promptly transfer and deliver to POZEN all (A) Promotional Materials (including any copyright rights therein; provided,

 (iii) GSK will assign to POZEN, to the extent assignable and at
POZEN’s request, GSK’s rights in any or all Third Party agreements for licenses, services or supplies necessary for the development or Commercialization of all Collaboration Products, including without limitation, any agreements with a
Third Party regarding the formulation of all Collaboration Products. To the extent that any agreement is not assignable by GSK, then such agreement will not be assigned, and upon the request of POZEN, GSK will cooperate in good

 faith and use commercially reasonable efforts to allow POZEN to obtain and to enjoy the benefits of such agreement in the
form of a license or other right to the extent held by GSK subject to such Third Party’s rights.  
  
 (iv) Effective upon the effective date of such termination, 
  
 (1) GSK hereby grants to POZEN a [***] license, with the right to grant and authorize the grant of sublicenses,
under any GSK Patents and GSK Know-How that constitute Product Specific Improvements to develop, make, have made, use, sell, offer for sale and import Products. 
  

(2) GSK hereby grants to POZEN a [***] license, with the right to grant and authorize the grant of sublicenses, under any GSK Formulation
Technology to develop, make, have made, use, sell, offer for sale and import Collaboration Products in the dosage strength, formulation and Presentation as developed by GSK under this Agreement so long as GSK is obligated to supply POZEN with
Clinical Trial Material or commercial quantities of Collaboration Products under this Agreement. In the event GSK is not obligated to supply POZEN with Clinical Trial Material or commercial quantities of Collaboration Products under this Agreement
and POZEN requests a license to the GSK Formulation Technology, the license granted in this Section 12.4(a)(iv)(2) will be royalty bearing and the royalty will be equal to [***]% of Net Sales of such Collaboration Products. The term of such royalty
bearing license will be the longer of 10 years from the date of first commercial sale or the term of any Patent Controlled by GSK infringed by the manufacture or sale of such Collaboration Product containing the GSK Formulation Technology.

  
 (3) If the First Commercial Sale of a Product has
occurred prior to the effective date of termination and such termination is effective prior to the expiration of the [***], GSK hereby grants POZEN a [***] license, with the right to grant and authorize the grant of sublicenses, under the [***] to
develop, make, have made, use, sell, offer for sale and import Collaboration Products in the dosage strength, formulation and Presentation as developed by GSK under this Agreement and for the First Commercial Sale has occurred. For the avoidance of
doubt, notwithstanding any provision hereof to the contrary, GSK is not granting POZEN any license rights under the [***] to sell Collaboration Products prior to the expiration of the [***] unless the effective date of termination is after the First
Commercial Sale of a Collaboration Product and not in connection with any Collaboration Product that has not been the subject of a First Commercial Sale. 
  
 (4) Any sublicense of a right granted to POZEN under this Section will be made subject to the terms of this Agreement and any action or omission
by such sublicensee that would, if committed by POZEN, constitute a breach of this Agreement, will be deemed a breach of this Agreement by POZEN. POZEN will impose on any sublicensee obligations corresponding to POZEN’s obligations hereunder.

 (v) If the First Commercial Sale of a Collaboration Product has occurred as of the effective date
of termination, GSK will consider, in its sole discretion, licensing to POZEN the GSK Marks for use solely in connection with such Collaboration Product in consideration for a royalty not to exceed [***] percent ([***]%) of POZEN’s Net Sales of
such Collaboration Product using the GSK Marks. 
  
 (vi)
GSK will, pursuant to a supply agreement to be negotiated in good faith by the Parties, supply POZEN with Clinical Trial Materials and commercial quantities of Collaboration Products in the dosage strength, formulation and presentation under
development or being Commercialized by GSK, in either case, as of the effective date of termination until the earlier of: (A) three (3) years after the effective date of termination; or (B) establishment by POZEN of an alternative supply for such
Collaboration Product (after expiration of the GSK Sumatriptan Patents) on commercially reasonable terms. If such termination occurs prior to NDA Approval of a Collaboration Product, GSK will supply Clinical Trial Materials for such Collaboration
Product to POZEN at a price equal to [***]% ( plus the costs of freight from the GSK facility to the POZEN facility) for the purpose of conducting clinical trials; provided, however, GSK will not be obligated to supply such Clinical
Trial Material if the Collaboration Product in question has suffered a Product Failure. If the First Commercial Sale of a Collaboration Product has occurred as of the effective date of termination and such date is prior to expiration of the GSK
Sumatriptan Patents, GSK will supply commercial quantities of such Collaboration Product to POZEN at a price comparable to that paid by SmithKline Beecham Corporation for sumatriptan in its finished form. If the First Commercial Sale of a
Collaboration Product has occurred as of the effective date of termination, and such date is after the expiration of GSK’s U.S. Patent covering its sumatriptan product, and Generic Erosion of sumatriptan has occurred, GSK will supply such
Collaboration Product to POZEN at a price equal to [***]% (plus the costs of freight from the GSK facility to the POZEN facility). 
  
 (vii) In addition, if the First Commercial Sale for a Collaboration Product has occurred at the time of such termination, then at POZEN’s
election, (A) GSK will transfer to POZEN GSK’s existing inventory of such Collaboration Product as is in good and saleable condition, in its original, unopened packaging, at the transfer price paid by GSK for such Collaboration Product, or (B)
GSK will have the right to sell-through its existing inventory of such Collaboration Product for a period not to exceed six (6) months from the effective date of termination. At the end of any such sell-through period, all unsold inventory will be
returned to POZEN, and POZEN will repurchase such inventory from GSK as is in good and saleable condition, in its original, unopened packaging, at the transfer price paid by GSK for such Collaboration Product. 
  
 (viii) In connection with any supply or transfer of Clinical Trial
Material or commercial supply of Collaboration Products and for so long as GSK supplies the foregoing to POZEN or POZEN is using such Clinical Trial Materials or selling the commercial supply of such Collaboration Product, GSK will grant to POZEN
rights of reference (and a letter of

 authorization to FDA to that effect) to any GSK IND or NDA pertaining to sumatriptan. Upon the expiration of such right,
POZEN will send written notice to such effect to the FDA. If POZEN elects to continue any ongoing studies using Sumatriptan or Clinical Trial Material supplied by GSK, GSK will continue to support CMC aspects of the respective IND with appropriate
documentation in order to allow completion of any such studies. The foregoing in no way is meant to confer any rights to POZEN to subsequently commercialize the particular Collaboration Product using Sumatriptan or for commercial supply prior to
expiry of the GSK Sumatriptan Patents (absent a license from GSK or right to such supply, as otherwise provided for under this Agreement). 
  
 (ix) In the event this Agreement is terminated by either Party as the result of a [***], GSK will not be obligated to make the transfers,
assignments or deliveries or take other actions described in Sections 12.4(a)(ii), 12.4(a)(v), 12.4(a)(vi), 12.4(a)(vii) and 12.4(viii). 
  
 (b) Termination by GSK for POZEN Breach. If POZEN is in material breach of its obligations hereunder, then following the expiration of any
applicable Cure Period described in Section 12.2, GSK may elect to either: 
  
 (i) Terminate this Agreement in its entirety; or 
  
 (ii) Elect to continue to exercise its rights under this Agreement, in which case: 
  
 (1) The rights and obligations of the Parties under this Agreement will remain in full force and effect; provided that GSK will assume the
obligations of POZEN under the Development Program and Development Plan in respect of the Lead Product and will perform any and all obligations thereunder in accordance with the terms of this Agreement and provided further that
POZEN’s participation on all joint committees will be terminated as well as any co-promotion arrangement, or unexercised co-promotion option held by POZEN. 
  

(2) GSK may, as its sole and exclusive remedy hereunder, off-set any direct damages resulting from POZEN’s breach of this Agreement from
any payments due to POZEN under this Agreement, provided that such off-set will not reduce the total amount of any such payment by more than [***]%; 
  
 (c) Expiration. Upon expiration of this Agreement pursuant to Section 12.1(a)(i), GSK will retain an exclusive, fully-paid, royalty-free
license to use any proprietary POZEN Know-How that GSK is using in the manufacture or sale of any Collaboration Product at the time of such expiration only for the purpose of continuing to make, use, offer for sale, sell and import such
Collaboration Product in the Field and Territory.

of time specified in such Section. Termination of this Agreement will not relieve the Parties of any liability which accrued hereunder prior to the effective date of such termination, including any payment obligations, nor preclude either Party from
pursuing all rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement nor prejudice either Party’s right to obtain performance of any obligation. 
  
 13. DISPUTE RESOLUTION. 
  
 13.1 Disputes. 
  
 (a) The Parties recognize that disputes as to certain matters may
from time to time arise during the Term that relate to either Party’s rights and/or obligations hereunder. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement in an
expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in this Section 13.1 if and when a dispute arises under this Agreement. All disputes arising
under this Agreement will be discussed first by the Joint Project Team. Either Party may, by written notice to the other Party, have any dispute between the Parties remaining unresolved after thirty (30) days referred to their respective executive
officers designated below or their successors for attempted resolution by good faith negotiations within thirty (30) days after such notice is received. Such designated officers are as follows: 
  
 For
GSK:          President, US Pharmaceuticals, GSK 
  
 For POZEN:     Chief Executive Officer 
  
 (b) If the designated officers are still not able to resolve such dispute within such thirty (30) day period, either
Party may at any time thereafter pursue any legal or equitable remedy available to it. Notwithstanding anything to the contrary herein, this Section 13.1 will not apply in respect of any alleged breach of Sections 2.1, 2.4, 2.6 or Section 11.

  
 13.2 Governing Law; Judicial Resolution. Resolution of

 substantive laws of the State of North Carolina, excluding any choice of law rules that may direct the application of the
law of another state. Any dispute arising under this Agreement will be submitted to a state or federal court of competent jurisdiction within the State of North Carolina, except as otherwise expressly provided in this Agreement, and each Party
agrees to the exclusive jurisdiction and venue of such courts. 
  
 13.3 Patent and Trademark Dispute Resolution. Any dispute, controversy or claim between the Parties relating to the scope, validity, enforceability or infringement of any patent rights covering the manufacture, use or sale of a
Product or of any trademark rights relating to a Product will be submitted to a court of competent jurisdiction in the territory in which such patent or trademark rights were granted or arose. 
  
 14. MISCELLANEOUS. 
  
 14.1 Performance by Affiliates and Subcontractors. The Parties
recognize that each Party may perform some or all of its obligations under this Agreement through Affiliates or Third Party subcontractors unless otherwise expressly limited herein; provided, however, that each Party will remain
responsible for the performance by its Affiliates and subcontractors and will cause its Affiliates and subcontractors to comply with the provisions of this Agreement in connection with such performance. Each Party hereby expressly waives any
requirement that the other Party exhaust any right, power or remedy, or proceed against an Affiliate or subcontractor, for any obligation or performance hereunder prior to proceeding directly against such Party. Wherever in this Agreement the
Parties delegate responsibility to Affiliates or local operating entities, the Parties agree that such entities may not make decisions inconsistent with this Agreement, amend the terms of this Agreement or act contrary to its terms in any way.

  
 14.2 Assignment. Neither Party may assign or transfer
this Agreement or any rights or obligations hereunder without the prior written consent of the other, except that a Party may assign this Agreement without the other Party’s consent (i) in part or in its entirety to an Affiliate or (ii) in its
entirety to a successor to substantially all of the business of such Party, whether in a merger, consolidation, sale of stock, sale of assets or other corporate transaction. Any permitted successor or assignee of rights and/or obligations hereunder
will, in a writing to the other Party, expressly assume performance of such rights and/or obligations. The POZEN Patents and POZEN Know-how and the GSK Patents and GSK Know-how will exclude any intellectual property held or developed by a permitted
successor of the relevant Party not in connection with a Collaboration Product. Any permitted assignment will be binding on the successors of the assigning Party. Any assignment or attempted assignment by either Party in violation of the terms of
this Section 14.2 will be null and void and of no legal effect ab initio. 
  
 14.3 Independent Contractors. The Parties hereto 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 hereto 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.

  
 14.4 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, but any such waiver will be effective only if set forth in a written instrument that explicitly refers to this Agreement and is duly executed by or on behalf of the Party waiving such provision
or requirement. 
  
 14.5 Amendment. Except as expressly
provided otherwise herein, the Parties hereto may amend, modify or alter any of the provisions of this Agreement, but such amendment, modification or alteration will be valid and binding only if memorialized by a written instrument that explicitly
refers to this Agreement and is duly executed by both Parties hereto. 
  
 14.6 Severability. If any one or more of the provisions of this Agreement is held to be invalid or unenforceable by any court of competent jurisdiction from which no appeal can be or is taken, the provision will be considered severed
from this Agreement and will not serve to invalidate any remaining provisions hereof. The Parties will make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated
by the Parties when entering this Agreement may be realized. 
  
 14.7 Notices. Any notice required or permitted to be given under this Agreement will be in writing, will specifically refer to this Agreement and will be deemed to have been sufficiently given for all purposes (a) if mailed by first
class certified or registered mail (postage prepaid), express delivery service or personally delivered, (b) if sent by facsimile or electronic mail, with electronic transmission confirmed. Unless otherwise specified in writing, the mailing addresses

foreseen by such Party, including without limitation, fire, earthquake, acts of God, acts of war, strikes, lockouts, or other labor disputes, riots, civil disturbances, actions or inactions of governmental authorities (except actions in response to
a breach of applicable laws by such Party), or epidemics. This Section 14.8 will not operate to excuse payment by GSK of any amounts due to POZEN under this Agreement. In the event of any such force majeure, the Party affected will promptly notify
the other Party, will use commercially reasonable efforts to overcome such force majeure, and will keep the other Party informed with respect thereto.

including debtor-in-possession) and its successors and assigns (including, without limitation, a Title 11 Trustee) will immediately upon the request of the non-Bankrupt Party deliver one copy of the IP Materials to a commercial escrow agent mutually
agreeable to the Parties (the “Escrow Agent”), and will enter into a binding contractual arrangement with such Escrow Agent according to which the Escrow Agent will agree (i) to hold and safeguard the escrowed IP Materials during

 (b) The non-Bankrupt Party will have a right to receive from the Escrow Agent one copy of the
escrowed IP Materials solely in the event that a Title 11 case is commenced by or against the Bankrupt Party and (i) this Agreement is rejected as provided in Title 11 and the non-Bankrupt Party elects to retain its rights hereunder as provided in
Title 11, or (ii) the Bankrupt Party otherwise fails to perform all of its obligations under this Agreement (any of such circumstances, a “Trigger Event”). The Bankrupt Party will authorize the Escrow Agent to deliver to the
non-Bankrupt Party one copy of the escrowed IP Materials, provided that (i) the non-Bankrupt Party has in good faith provided to the Escrow Agent a written notice, certified by an officer of the non-Bankrupt Party, asserting the occurrence of a
Trigger Event satisfying the requirements of this Section 14.13(b); (ii) the Escrow Agent has transmitted to the Bankrupt Party a copy of the written notice provided by the non-Bankrupt Party; and (iii) the Bankrupt Party has failed to provide
notice to the Escrow Agent, within thirty (30) days after receipt thereof, stating that the Bankrupt Party either (x) disputes the occurrence of a Trigger Event, or (y) intends to remedy such events or cure such circumstances within thirty (30) days
thereafter. The non-Bankrupt Party acknowledges that the Escrow Agent will not be authorized to deliver or otherwise provide access to the escrowed IP Materials in the event that the Bankrupt Party provides such notice to the Escrow Agent, unless
and until ordered to do so by a court of competent jurisdiction. 
  
 (c) Subject to the non-Bankrupt Party’s compliance with the terms and conditions of this Section 14.13, upon the delivery to the non-Bankrupt Party of any escrowed IP Materials in accordance with this Section 14.13, the
non-Bankrupt Party will have the right to perform the obligations of the Bankrupt Party hereunder with respect to such intellectual property, but neither such provision nor such performance by the non-Bankrupt Party will release the Bankrupt Party
from any such obligation or liability for failing to perform it. 
  
 (d) All rights, powers and remedies of the non-Bankrupt Party provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including,
without limitation Title 11) in the event of the commencement of a Title 11 case by or against the Bankrupt Party. The non-Bankrupt Party, in addition to the rights, power and remedies expressly provided herein, will be entitled to exercise all
other such rights and powers and resort to all other such remedies as may now or hereafter exist at law or in equity including, without limitations, under Title 11) in such event. The Parties agree that they intend the foregoing non-Bankrupt Party
rights to extend to the maximum extent permitted by law and any provisions of applicable contracts with Third Parties, including without limitation for purposes of Title 11, (i) the right of access to any intellectual property (including all
embodiments thereof) of the Bankrupt Party or any Third Party with whom the Bankrupt Party contracts to perform an obligation of the Bankrupt Party under this Agreement, and, in the case of the Third Party, which is necessary for the development,
registration and manufacture of licensed products and (ii) the right to contract directly with any Third Party described in (i) in this sentence to complete the contracted work. Any intellectual

 Schedule 4.5 
  
 If the Parties are unable to agree on matters subject to a dispute to be referred to this Schedule 4.5, the matter will be resolved
as follows: 
  

					
	1.1	  	The Parties will refer any such dispute to the Chief Executive Officer of POZEN and the President, US Pharmaceuticals for GSK for attempted resolution by good faith
negotiations.
			
	1.2	  	(a)	  	If the designated officers are not able to resolve the dispute within thirty (30) days after being presented with it, the Parties will select a mutually agreeable arbitrator who has
significant relevant experience in the field of developing or licensing, as the dispute may require, pharmaceutical products and no affiliation or pre-existing relationship with either POZEN or GSK (“Arbitrator”). If the Parties are
unable to agree on an arbitrator within such 30 day period, then each Party will select an arbitrator within 5 business days, the two (2) designated arbitrators will select a mutually agreeable third arbitrator within five (5) business days
satisfying the criteria described in the immediately preceding sentence and all three (3) arbitrators will hear the dispute as a panel and render a decision upon the determination of the majority of the panel (such panel referred herein as the
“Arbitrator” for purposes of this Schedule 4.5). The date on which such Arbitrator is selected will be the “Arbitration Commencement Date.”
			
	 	  	(b)	  	Within fifteen (15) business days of selecting the Arbitrator, each Party will prepare and deliver to both the Arbitrator and the other Party its proposed solution of the dispute and a
memorandum (“Support Memorandum”) in support thereof. The Arbitrator will also be provided with a copy of this Agreement.
			
	 	  	(c)	  	Within ten (10) business days of receipt of the other Party’s Support Memorandum, each Party may submit to the Arbitrator (with a copy to the other Party) a rebuttal to the other
Party’s Support Memorandum (a “Rebuttal”), which may include a revision, marked to show changes, of either Party’s proposed solution.
			
	 	  	(d)	  	Neither Party may have communications (either written or oral) with the Arbitrator other than for the sole purpose of engaging the Arbitrator or as expressly permitted in this Schedule
4.5.
			
	 	  	(e)	  	Within thirty (30) days of the Arbitration Commencement Date, the Arbitrator will issue a decision resolving the dispute. The decision of the Arbitrator will be binding and enforceable among
POZEN and GSK.
			
	 	  	(f)	  	The Arbitrator will have reasonable discretion to request additional information, hold a hearing, and extend the time frame for reaching his or her decision regarding the dispute at
issue.

	 	  	(g)	  	To the extent any further arbitration rules or procedures are necessary for resolution of the dispute at issue, the rules of the American Arbitration Association will apply. Notwithstanding
the foregoing, the Parties are not required to select an arbitrator from the American Arbitration Association’s panel of arbitrators.
		
	1.3	  	The Arbitrator’s fees and expenses will be shared by the Parties. Each Party will bear and pay its own expenses incurred in connection with any contract resolution under this
Schedule 4.5.
