any such transaction will be calculated as follows: 
  

					
	A	  	×	  	Net Sales of the Product Set, where:
	A+B	  	  
		
	  A =	  	Standard Sales Price of the Product if sold separately from the Product set in question, in the Territory.
		
	  B =	  	The total of the Standard Sales Prices of all products in the Product Set other than the Product, in the Territory.

	8.	FINANCIAL TERMS 

 8.1 Royalties. 

8.1.1 Royalty Rate. Subject to the terms and conditions of this Agreement, Licensee will pay to POZEN royalties based on the aggregate
annual Net Sales of Products sold by Licensee, its Affiliates or Sublicensees, at the rate of 10% of aggregate Net Sales of Products sold in the Territory. 

8.1.2 Royalty Term. Licensee acknowledges that it will continue to enjoy substantial benefit from its license under, and the transfer
to Licensee of certain elements of, the Licensed Technology pursuant to this Agreement (including the Licensed Know-How and the regulatory data to be provided to Licensee pursuant to this Agreement) as well as from Licensee’s own development of
technology derived from the practice of such license and Licensee’s use of such Licensed Technology, even after expiration of all Valid Claims of the Licensed Patents covering the composition of matter, manufacture, use or sale of POZEN Product
in the Territory. Accordingly, subject to the terms of Section 8.1.3 (Rate Step Down for Competing Product Entrants), Licensee’s royalty payment obligations under this Section 8.1 (Royalties) will commence upon First Commercial Sale of a
Product in the Territory and will expire upon the later of: (i) expiration of the last-to-expire Valid Claim of the Licensed Patents that, but for the licenses granted in this Agreement, would be infringed by the sale of such Product in the
Territory, and (ii) ten (10) years after the First Commercial Sale of such Product in the Territory (such period ending at the later of the periods set forth in clause (i) and (ii) above, the “Royalty Term”).

 8.1.3 Rate Step Down For Competing Product Entrants. With respect to any particular Product in the Territory, if in any Calendar
Quarter there is a Market Reduction of such Product (based on prescription market data published by IMS Health, Scott-Levin, or such other industry standard source as the Parties may agree), then the royalty rates which would otherwise apply to Net
Sales of such Product during such Calendar Quarter will be reduced to *** percent (***%). Such reduced royalty rates will continue in effect, on a Product-by-Product basis, until expiration of the applicable Royalty Term. As used in this
Section 8.1.3, the term “Market Reduction” of a Product in a Calendar Quarter occurs when (i) the cumulative share achieved by Competing Products for such Product commercialized by Third Parties in such *** of the *** in
the territory of the Product and Competing Products and (ii) the sales of the Product(s) in such *** are reduced by *** to the *** in which the *** of a Competing Product occurred. The example set forth in Schedule 8.1.3 illustrates the
application of this Section 8.1.3. 
 8.1.4 Third Party Payments. If Licensee or a Sublicensee determines that a license to certain
Third Party technology is reasonably necessary for the successful Development, Manufacture or Commercialization of a Product in the Territory, then Licensee will notify POZEN in writing of such determination. The Parties will consult in good faith
regarding the need for such Third Party technology and, subject to POZEN’s consent (not to be unreasonably withheld, conditioned or delayed), Licensee (or Sublicensee, if applicable) will negotiate the terms on which such a Third Party license
would be granted to Licensee and will serve as the primary point of contact with the applicable Third Party licensor following the execution of the license agreement. The royalties required to be paid by Licensee with respect to a Product pursuant
to Section 8.1 (Royalties) shall be subject to a reduction by Licensee in an amount equal to *** (***%) of the amount of *** that are *** under such *** in the *** for the

*** of such *** during the *** provided, that (i) *** of the *** of such *** pursuant to *** for such ***, and (ii) if such *** is a *** (i.e., *** for such ***). For clarity,
and notwithstanding anything to the contrary in this Agreement, AstraZeneca AB and its Affiliates shall be solely responsible for any Third Party payment obligations it may have to Merck & Co., Inc. or its affiliates, without any offset or
deduction. Any amount of Third Party Royalties that may, pursuant to the preceding paragraph be used to reduce royalties due hereunder, in any Calendar Quarter, but are not so used as a result of the limitation described in clause (i) of this
paragraph may be carried over and used for further reduction in any succeeding royalty payment due for such Product. 

8.1.5***. 
 8.2
Payments and Sales Reporting. 
 8.2.1 Sales Reporting. Licensee will provide POZEN, within *** *** (***) of the end of
each Calendar Quarter, with a report setting forth, on a Product-by-Product basis, the amount of gross sales of each Product in the Territory, a calculation of Net Sales and a calculation of the amount of royalty payment due on such Net Sales,
provided that Licensee shall use reasonable efforts to provide such report as soon as practicable to accommodate POZEN’s SEC filing requirements and to provide such reports in a shorter time period than the periods specified above if Licensee
has such reports available for its own internal purposes. If any payment reduction is claimed by Licensee under this Agreement from the full royalty rates set forth in Section 8.1 (Royalties), then the report will set forth in detail the claimed
reduction and the related facts. 
 8.2.2 Payment Timing. Licensee will make royalty payments to POZEN within *** (***) days of the
last day of each Calendar Quarter for which such payments are due under Section 8.1 (Royalties). 
 8.2.3 Payment Method. All amounts
due hereunder will be paid in United States Dollars by wire transfer in immediately available funds to the following account, or such other account as may be designated in writing by POZEN: 

 

			
	Receiving bank name:	  	***
	Receiving bank address:	  	***
	ABA routing number (1):	  	*** (1) - required for domestic transfers
	SWIFT BIC address (2):	  	*** (2) - required for international transfers
	For credit to the account of:	  	POZEN Inc.
	For credit to account number:	  	***

 8.2.4 Currency. All payments required under this Article 8 shall be made in U.S. Dollars. 

8.2.5 Late Payments. If a Party does not receive payment of any sum due to it on or before the due date, simple interest will
thereafter accrue on the sum due to such Party until the date of payment at the per annum rate of *** percent (***%) over the then-current *** quoted by Citibank in New York City, or the maximum rate allowable by Applicable Law, whichever is lower.

 8.3 Records; Audit. Licensee will maintain complete and accurate records in sufficient
detail to permit POZEN to confirm the accuracy of the calculation of payments under this Agreement. Upon reasonable prior notice, such records will be available during regular business hours of Licensee for a period of *** (***) calendar years
following the year in which such records were created, for examination at POZEN’s expense, and not more often than once each calendar year, by an independent certified public accountant selected by POZEN and reasonably acceptable to Licensee,
for the sole purpose of verifying the accuracy of the financial reports furnished by Licensee pursuant to this Agreement. Any such auditor will not disclose Licensee’s Confidential Information, except to the extent such disclosure is necessary
to verify the accuracy of the financial reports furnished by Licensee or the amount of payments due by Licensee under this Agreement. Any amounts shown to be owed but unpaid will be paid within *** (***) days from the accountant’s report, plus
interest (as set forth in Section 8.2.5 (Late Payments)) from the original due date. Any amounts determined to be overpaid will be refunded within *** (***) days from the accountant’s report. POZEN will bear the full cost of such audit unless
such audit discloses an underpayment of the amount actually owed during the applicable calendar year of more than *** percent (***%), in which case Licensee will bear the full cost of such audit. 

8.4 Taxes. 
 8.4.1
General. The royalties, milestones and other amounts payable by one Party to the other Party pursuant to this Agreement or the Three-Party Agreement (“Payments”) shall not be reduced on account of any taxes unless required by
Applicable Law. The Party receiving any Payment shall be responsible for paying any and all taxes (other than withholding taxes or deduction of tax at source required by Applicable Law to be paid by the paying Party) levied on account of, or
measured in whole or in part by reference to, any Payments it receives. The paying Party shall deduct or withhold from the Payments any taxes that it is required by Applicable Law to deduct or withhold. Notwithstanding the foregoing, if the Party
receiving payment is entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, applicable withholding tax, it may deliver to the paying Party or the appropriate governmental authority (with the assistance of the
paying Party to the extent that this is reasonably required and is expressly requested in writing) the prescribed forms necessary to reduce the applicable rate of withholding tax or to relieve the paying Party of its obligation to withhold tax, and
the paying Party shall apply the reduced rate of withholding tax, or dispense with withholding tax, as the case may be, provided that the paying Party has received evidence, in a form satisfactory to the paying Party, of the other Party’s
delivery of all applicable forms (and, if necessary, its receipt of appropriate governmental authorization) at least *** (***) days prior to the time that the Payments are due. If, in accordance with the foregoing, the paying Party withholds any
amount, it shall pay to the other Party the balance when due, make timely payment to the proper taxing authority of the withheld amount, and send to the other Party proof of such payment within *** (***) days following that payment.

 8.4.2 Indirect Taxes. Notwithstanding anything contained in Section 8.4.1 (General),
this Section 8.4.2 (Indirect Taxes) shall apply with respect to Indirect Taxes. All Payments are exclusive of Indirect Taxes. If any Indirect Taxes are chargeable in respect of any Payments, the paying Party shall pay the Indirect Taxes at the

	9.	INTELLECTUAL PROPERTY 

 9.1 Prosecution and Maintenance of Licensed Patents. POZEN
will be responsible for the preparation, filing, prosecution and maintenance of the Licensed Patents (other than Joint Patents), at its own expense. POZEN will provide a copy of all proposed filings at least *** (***) days in advance of the filing
date and will consider in good faith the requests and suggestions of Licensee with respect to filing and prosecuting the Licensed Patents and will keep Licensee promptly informed of progress with regard to the preparation, filing, prosecution and
maintenance of Licensed Patents. In the event that POZEN desires to abandon any Licensed Patent, POZEN will provide reasonable prior written notice to Licensee of such intention to abandon (which notice will, in any event, be given no later than ***
(***) days prior to the next deadline for any action that may be taken with respect to such Licensed Patent with the U.S. Patent & Trademark Office), and Licensee will have the right to assume responsibility for such Licensed Patent. For
clarity, any Patent with Valid Claims solely directed to any product containing acetyl salicylic acid (including salts and derivatives thereof) is not a Licensed Patent; therefore, Licensee will have no right to assume responsibility for such Patent
as provided under this Section 9.1 should Pozen decide to abandon such Patent. 
 9.2 Prosecution and Maintenance of Joint Patents.
Licensee will be responsible for the preparation, filing, prosecution and maintenance of Joint Patents, at its own expense. Licensee will provide to POZEN a copy of all proposed filings at least *** (***) days in advance of the filing date and will
consider in good faith the requests and suggestions of POZEN with respect to filing and prosecuting the Joint Patents and will keep POZEN promptly informed of progress with regard to the preparation, filing, prosecution and maintenance of Joint
Patents. In the event that Licensee desires to abandon any Joint Patent, Licensee will provide reasonable prior written notice to POZEN of such intention to abandon (which notice will, in any event, be given no later than *** (***) days prior to the
next deadline for any action that may be taken with respect to such Joint Patent with the U.S. Patent & Trademark Office), and POZEN will have the right to assume responsibility for such Joint Patent. 

9.3 Ownership of Inventions. Inventorship of Inventions will be determined in accordance with the rules of inventorship under United
States patent laws. Subject to the licenses granted under this Agreement, as between the Parties, Licensee will own all Licensee Inventions, POZEN will own all POZEN Inventions, and Joint Inventions will be owned jointly by Licensee and POZEN;
provided, however, that during the Term of this Agreement: (i) neither POZEN nor Licensee shall *** other than as expressly provided in this Agreement, including Section 7.1 (Licensed Technology), without the consent of the other
Party, which consent shall not be unreasonably withheld, conditioned or delayed, and (ii) neither Party shall assign, pledge, encumber, license or otherwise transfer any of its rights in any Joint Invention or Joint Patent without the other
Party’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. Upon any expiration or termination of this Agreement, each

Party will have the right to exploit, license and grant rights to sublicense each such Joint Invention and Joint Patent, without any duty of accounting to the other Party, and each Party hereby
consents, and agrees to consent, without payment of any further consideration or royalty, to the Joint Party’s exploitation and licensing of said Joint Party’s interest in such Joint Invention or Joint Patent to Third Parties; provided,
that nothing in this Section 9.3 gives either Party any right or license under any intellectual property rights Controlled by the other Party other than Joint Inventions and Joint Patents, regardless of whether such rights are necessary in
order to exploit the Joint Inventions and Joint Patents pursuant to this Section 9.3. The Parties acknowledge and agree that AstraZeneca AB owns all AstraZeneca Inventions (as defined in the Original Agreement) conceived under the Original
Agreement in the performance of activities undertaken pursuant to the Original Agreement solely by employees, agents, or independent contractors of AstraZeneca AB, its Affiliates or sublicensees prior to the Amended and Restated Effective Date.

Patents and Joint Patents and in the obtaining and maintenance of any patent extensions, supplementary protection certificates and the like with respect to the Licensed Patents and Joint Patents. Such cooperation includes, but is not limited to:
(a) executing all papers and instruments, or requiring its employees or contractors, to execute such papers and instruments, so as to effectuate the ownership of Inventions set forth in Section 9.3 (Ownership of Inventions), and Patents in
the Territory claiming or disclosing such Inventions, and to enable the other Party to apply for and to prosecute patent applications in the Territory; and (b) promptly informing the other Party of any matters coming to such Party’s
attention that may affect the preparation, filing, prosecution or maintenance of any such patent applications. 
 9.6 Enforcement of
Licensed Patents. 
 9.6.1 Infringement by Third Parties. Licensee and POZEN will each, within *** (***) Business Days of learning
of any alleged or threatened infringement of the Licensed Patents or Joint Patents, notify the other Party in writing. *** will have the first right, but not the obligation, to prosecute any such infringement. If *** does not commence an
infringement action against the alleged or threatened infringement (i) within *** (***) days following the detection of the of alleged infringement, or (ii) *** (***) Business Days before the time limit, if any, set forth in appropriate
laws and regulations for filing of such actions, whichever comes first, then *** will so notify *** promptly, and *** may commence litigation with respect to the alleged or threatened infringement at its own expense. For clarity, any Patent with
Valid Claims solely directed to any product containing acetyl salicylic acid (including salts and derivatives thereof) is not a Licensed Patent; therefore, *** will have no right to prosecute any infringement of such Patent under this Section 9.6.1.
Notwithstanding anything in this Section 9.6.1 to the contrary, *** shall not have the right to prosecute an infringement action under this Section 9.6.1 unless such action involves a Product.

first, then *** will so notify *** promptly, and *** may take action with respect to the alleged or threatened challenge at its own expense. For clarity, any Patent with Valid Claims solely directed to any product containing acetyl salicylic acid
(including salts and derivatives thereof) is not a Licensed Patent; therefore, *** will have no right to defend any challenge of such Patent under this Section 9.6.2. 

9.6.3 Cooperation. In the event a Party brings an infringement action pursuant to Section 9.6.1 (Infringement by Third Parties),
the other Party will cooperate fully, including, if required to bring such action, the furnishing of a power of attorney or to join such action as a necessary party, executing all papers and instruments, or requiring its employees or contractor, to
execute such papers and instruments, so as to successfully prosecute any such actions. Neither Party will have the right to settle any patent infringement litigation under this Section 9.6.3 (Cooperation) in a manner that could be reasonably
expected to diminish the rights or interest of the other Party, or adversely effect the validity or enforceability of such other Party’s Patents, without the express written consent of such other Party. The Party commencing the litigation will
provide the other Party with copies of all pleadings and other documents filed with the court and will consider reasonable input from the other Party during the course of the proceedings. 

9.6.4 Recovery. Except as otherwise agreed by the Parties in connection with a cost sharing arrangement, any recovery realized as a
result of such litigation described in Section 9.6.1 (Infringement by Third Parties) (whether by way of settlement or otherwise) will be first allocated to reimbursement of unreimbursed legal fees and all litigation expenses incurred by the Party
initiating the proceeding, then toward reimbursement of any of unreimbursed legal fees and all litigation expenses of the other Party, and then the remainder will be divided between the Parties as follows: (a) settlements, damages or other
monetary awards recovered pursuant to a suit, action or proceeding brought by *** will be *** and subject to *** set forth in ***; and (b) settlements, damages or other monetary awards recovered pursuant to a suit, action or proceeding brought

 9.7 Defense of Infringement Claims. If the manufacture, sale or use of a POZEN Product pursuant to this
Agreement results in any claim, suit, or proceeding by a Third Party alleging that such activities infringe a Third Party patent, or if a Third Party threatens such a claim, suit or proceeding, each Party will promptly notify the other Party
thereof. *** *** will have the exclusive right to defend and control the defense of any such claim, suit or proceeding at its own expense, using counsel of its own choice; provided, that if any such proceedings involve matters relating to the
validity or enforceability of the Licensed Patents or Joint Patents, then the provisions of Section 9.6.3 (Cooperation) above shall apply. In any claim, suit or proceeding under this Section 9.7, *** will keep *** reasonably informed of all material

participate in the defense using counsel of its choice at its own expense. In any claim, suit or proceeding under this Section 9.7, *** agrees to provide *** with copies of all pleadings filed in such action and to allow *** reasonable opportunity

 9.8 Patent Term Extension and Supplementary Protection Certificate. Upon receiving
Marketing Approval for a POZEN Product, the Parties agree to coordinate the application for any patent term extension or supplementary protection certificates that may be available. The primary responsibility of applying for any extension or
supplementary protection certificate will be the Party having the right to make the application under the Applicable Law. The Party responsible for filing the application will keep the other Party fully informed of its efforts to obtain such
extension or supplementary protection certificate. Each Party will provide prompt and reasonable assistance, without additional compensation, to obtain such patent extension or supplementary protection certificate. The Party filing such request will
pay all expenses in regard to obtaining the extension or supplementary protection certificate. 
 9.9 Consequence of Patent
Challenge. If Licensee or its Affiliates challenge the validity or enforceability of any of the Licensed 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 shall give POZEN the right to terminate this
Agreement as provided in Section 12.3 (Termination for Material Breach) or to terminate all licenses granted under any of the Licensed Patents subject to such Patent Challenge; provided, that the foregoing provisions of this Section 9.9 (Consequence
of Patent Challenge) will not apply in the event that, prior to such Patent Challenge, POZEN or any of its licensees or assignees initiates or threatens litigation against, or makes claims or assertions against, Licensee or its Affiliates,
Sublicensees or Third Party contractors, that allege that any of such parties infringe a Licensed Patent. 
 9.10 Patent Certifications.

 9.10.1 Orange Book Listings. To the extent required or permitted by Applicable Law, Licensee will use Diligent Efforts to

 9.10.2 Hatch-Waxman Act. Notwithstanding Section 9.6.1 (Infringement by Third
Parties) above, each Party 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 Licensed Patents is invalid, unenforceable or that any infringement will
not arise from the manufacture, use or sale of the POZEN Product by a Third Party. If Licensee decides not to bring infringement proceedings against the entity making such a certification with respect to any such Licensed Patents, Licensee will give

Licensee 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. For clarity, any Patent
with Valid Claims solely directed to any product containing acetyl salicylic acid (including salts and derivatives thereof) is not a Licensed Patent; therefore, Licensee will have no right to bring infringement proceedings of such Patent under this
Section 9.10.2. Notwithstanding anything in this Section 9.10.2 to the contrary, Licensee shall not have the right to bring an infringement proceeding under this Section 9.10.2 unless such proceeding involves a POZEN Product.

	11.	CONFIDENTIALITY. 

 11.1 Definition. “Confidential Information” means
information, including scientific and manufacturing information and plans, marketing and business plans, and financial and personnel matters relating to a Party or its present or future products, sales, suppliers, customers, employees, investors or

obligations hereunder or (b) in connection with (i) that certain confidentiality agreement between POZEN and AstraZeneca AB dated as of March 27, 2006, (ii) that certain confidentiality agreement between POZEN and AstraZeneca AB
dated as of June 15, 2006 or (iii) the Original Agreement, in each case ((i), (ii) and (iii)), except to the extent that such information relates exclusively to the exploitation of Products outside the Territory. Notwithstanding the
foregoing or any other provision of this Agreement to the contrary, during the Term, the Licensed Know-How will be deemed to be the Confidential Information of both Parties. 

11.2 Exclusions. Notwithstanding the foregoing, information of a Disclosing Party will not be deemed Confidential Information with
respect to a Receiving Party for purposes of this Agreement to the extent the Receiving Party can demonstrate by competent evidence that such information:

 11.2.3 became generally available or otherwise became part of the public domain after

Agreement any Confidential Information of the Disclosing Party. The Receiving Party may use such Confidential Information only to the extent required to accomplish the purposes of this Agreement or in connection with the exercise of its rights

quash such order and to obtain a protective order requiring that the Confidential Information and documents that are the subject of such order be held in confidence by such court or governmental or regulatory body or, if disclosed, be used only for
the purposes for which the order was issued; and provided, further, that if a disclosure order is not quashed or a protective order is not obtained, the Confidential Information disclosed in response to such court or governmental order will
be limited to that information which is legally required to be disclosed in response to such court or governmental order; 
 11.4.2
otherwise required by law; provided, that the Disclosing Party will provide the Receiving Party with notice of such disclosure at least *** (***) days in advance thereof to the extent practicable and take reasonable steps as requested by

press releases and other written public disclosures relating to this Agreement or the Parties’ relationship hereunder (each, a “Public Disclosure”), each Party will use reasonable efforts to submit to the other Party a draft of
such Public Disclosures for review and comment by the other Party at least *** (***) Business Days prior to the date on which such Party plans to release such Public Disclosure, and in any event will submit such drafts at least *** *** prior to the

 11.7 Terms of Agreement to be Maintained in Confidence. The Parties agree that the
terms of this Agreement are confidential and will not be disclosed by either Party to any Third Party (except to a Party’s professional advisors, including without limitation accountants, financial advisors, and attorneys) without prior written
permission of the other Party; provided, however, that (a) either Party may make any filings of this Agreement required by law or regulation in any country so long as such Party uses its reasonable efforts to obtain confidential treatment for
portions of this Agreement as available, consults with the other Party, and permits the other Party to participate, to the greatest extent practicable, in seeking a protective order or other confidential treatment; (b) either Party may disclose
this Agreement on a confidential basis to existing or potential Third Party investors, lenders or acquirors or, in the case of Licensee, to existing or potential Sublicensees, in each case in connection with due diligence or similar investigations;
and (c) a Party may publicly disclose, without regard to the preceding requirements of this Section 11.7, information that was previously disclosed in compliance with such requirements. 

 

	12.	TERM AND TERMINATION 

 12.1 Amended and Restated Effective Date. This Agreement
(other than this Section 12.1, which is binding and effective as of the Amended and Restated Execution Date), shall not become effective unless and until the closing of a Divestiture occurs (the date of such closing, the “Amended and
Restated Effective Date”), and upon the Amended and Restated Effective Date this Agreement and all of its terms and provisions shall be automatically effective and binding on both Parties. The Original Agreement shall not be amended and
restated or otherwise superseded by this Agreement until the Amended and Restated Effective Date. If the Amended and Restated Effective Date has not occurred by December 31, 2013, then this Agreement, including this Section 12.1, shall
terminate and be of no further force and effect. For clarity, such termination will not give rise to any of the effects or consequences set forth in Section 12.5. 

12.2 Term. The term of this Agreement will commence as of the Effective Date and, unless earlier terminated in accordance with
this Section 12 (Term and Termination), will expire upon the expiration of the Royalty Term for all POZEN Products in the Territory (the “Term”). 

12.3 Termination for Material Breach. In the event that either Party (the “Breaching Party”) shall be in material
default of any of its material obligations under this Agreement, in addition to any other right and remedy the other Party (the “Non-Breaching Party”) may have, the Non-Breaching Party may terminate this Agreement in its entirety by
*** (***) days prior written notice (the “Notice Period”) to the Breaching Party, specifying the breach and its claim of right to terminate; provided, that the termination shall not become effective at the end of the Notice Period
if the Breaching Party cures the breach complained about during the Notice Period (or, if such default cannot be cured within such Notice Period, if the Breaching Party commences actions to cure such default within the Notice Period and thereafter
diligently continues such actions). It is understood that termination pursuant to this Section 12.3 (Termination for Material Breach) shall be a remedy of last resort and may be invoked only in the case where the breach cannot be reasonably remedied
by the payment of money damages or other remedy under applicable law. If either Party initiates a dispute resolution procedure as permitted under this Agreement prior to the end of the Notice Period to


  
 -31-

resolve the dispute for which termination is being sought and is diligently pursuing such procedure, including any litigation following therefrom, the termination shall become effective only if
and when such dispute is finally resolved through such dispute resolution procedure. This Section 12.3 (Termination for Material Breach) defines exclusively the Parties’ right to terminate in case of any material breach of this Agreement. 

12.4 Termination for Cause. If a Post-Approval Failure occurs in the Territory, Licensee may, at its option, terminate the Agreement in
its entirety; provided, that written notice of termination must be delivered to POZEN within ***(***) days following such Post-Approval Failure. 

12.5 Consequences of Expiration and Termination. 

12.5.1 Effect of Expiration. Upon expiration (but not earlier termination) of the Term pursuant to Section 12.2 (Term), Licensee will
have a non exclusive, irrevocable, perpetual, fully-paid license, with the right to sublicense, under the Licensed Technology to research, develop, make, use, sell, offer for sale, and import the POZEN Product in the Field of Use in the Territory.

 12.5.2 Effect of Termination. The use by either party hereto of a termination right provided for under this Agreement and in
accordance with this Agreement shall not give rise to the payment of damages or any other form of compensation or relief to the other party with respect thereto. Subject to the preceding sentence, termination of this Agreement shall not preclude
either party from claiming any other damages, compensation or relief that it may be entitled to upon such termination or for any breach of this Agreement. If either Party terminates this Agreement, all rights and licenses granted by POZEN to
Licensee and all obligations of Licensee and POZEN under this Agreement will terminate immediately. 
 12.6 Termination for
Insolvency. This Agreement may be terminated by written notice by either Party at any time during the Term upon the declaration by a court of competent jurisdiction that the other Party is bankrupt and, pursuant to the U.S. Bankruptcy Code such
other Party’s assets are to be liquidated; upon the filing or institution of bankruptcy, liquidation or receivership proceedings (other than reorganization proceedings under Chapter 11 of the U.S. Bankruptcy Code); or upon an assignment of a
substantial portion of the assets for the benefit of creditors by the other Party; or in the event a receiver or custodian is appointed for such Party’s business; provided, however, that in the case of any involuntary proceeding, such right to
terminate shall only become effective if the proceeding is not dismissed within 60 days after the filing thereof (each of the foregoing, a “Bankruptcy Event”). 

12.7 Effect of Bankruptcy. All rights and licenses with respect to Patents and Know-How granted under or pursuant to this Agreement by
one Party to the other Party are, for all purposes of Section 365(n) of Title 11 of the United States Code (“Title 11”), licenses of rights to “intellectual property” as defined in Title 11. Each Party agrees that the
other Party, as licensee of such rights under this Agreement shall retain and may fully exercise all of its rights and elections under Title 11. POZEN *** Licensee *** POZEN *** POZEN *** (i) *** (ii) *** (iii) *** (iv) ***
(v) *** (vi) ***, and (vii) ***, and (viii) ***. POZEN agrees not to interfere with Licensee and its Affiliates’ exercise of rights and licenses to intellectual property

licensed hereunder and embodiments thereof in accordance with this Agreement and agrees to use commercially reasonable efforts to assist Licensee and its Affiliates to obtain such intellectual
property and embodiments thereof in the possession or control of Third Parties as reasonably necessary or desirable for Licensee or its Affiliates to exercise such rights and licenses in accordance with this Agreement. Each party agrees and
acknowledges that all payments by Licensee to POZEN payable under this Agreement other than royalty payments pursuant to Section 8.1 (Royalties) and commercialization milestone payments under the Three-Party Agreement do not constitute
“royalties” within the meaning of Section 365(n) of Title 11 or relate to licenses of intellectual property hereunder. 

12.8 Formulation Technology. If Licensee terminates this Agreement for any reason other than for material breach by POZEN under
Section 12.3 or as a result of POZEN’s insolvency under Section 12.7, then, subject to the terms and conditions of this Agreement, Licensee agrees to grant to POZEN, and does hereby grant effective automatically upon such termination,
(a) a perpetual, irrevocable, non-exclusive license or sublicense under the Formulation Technology, with the right to grant sublicenses and authorize the grant of sublicenses to the extent provided in this Section 12.8, to make, have made,
use, sell, offer for sale, and import POZEN Products in the Territory and (b) a perpetual, irrevocable, non-exclusive license or sublicense, as applicable, under the Formulation Technology, with the right to grant sublicenses and authorize the
grant of sublicenses to the extent provided in this Section 12.8, to Develop and Manufacture (but not sell or otherwise Commercialize) POZEN Products outside the Territory solely in support of the Development or Commercialization of the POZEN
Products in the Territory; provided, that nothing herein gives POZEN any right or license under any other intellectual property rights Controlled by Licensee, regardless of whether such rights are necessary in order to exploit the Formulation
Technology pursuant to this Section 12.8. POZEN may grant sublicenses and the right to grant further sublicenses under the foregoing license only as follows: (i) for any sublicense relating to the development or commercialization of a
POZEN Product Commercialized by Licensee in the Territory at the time of such termination (a “Commercialized POZEN Product”) in the Territory, POZEN may grant such sublicense upon notice to Licensee, but without obtaining
Licensee’s consent, and (ii) for any sublicense relating to POZEN Products other than Commercialized POZEN Products in the Territory, POZEN may grant such sublicense with Licensee’s prior written consent (such consent not to be
unreasonably withheld, conditioned or delayed). 
 12.9 Survival. Expiration or termination of this Agreement will not relieve the
Parties of any obligation accruing prior to such expiration or termination. The provisions of Sections 8.1 (Royalties), 8.2 (Payments and Sales Reporting), 8.3 (Records; Audits), 9.2 (Prosecution and Maintenance of Joint Patents), 9.3 (Ownership of
Inventions), 10.3 (Disclaimer of Warranty), 11 (Confidentiality), 12.5 (Consequences of Expiration and Termination), 12.7 (Effect of Bankruptcy), 12.8 (Formulation Technology), 12.9 (Survival), 13 (Indemnification and Insurance), 14 (Limitation of
Liability), and 15 (Miscellaneous) will survive any termination or expiration of this Agreement (other than a termination pursuant to Section 12.1).

	13.	INDEMNIFICATION AND INSURANCE 

 13.1 Indemnification by POZEN. POZEN hereby agrees
to save, defend and hold Licensee and its Affiliates and their respective directors, officers, employees and agents (each, a “Licensee Indemnitee”) harmless from and against any and all claims, suits, actions, demands, liabilities,
expenses and/or loss, including reasonable legal expense and attorneys’ fees (collectively, “Losses”), to which any Licensee Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any
Third Party to the extent such Losses arise directly or indirectly out of: (i) the gross negligence or willful misconduct of any POZEN Indemnitee or (ii) the breach by POZEN of any warranty, representation, covenant or agreement made by
POZEN in this Agreement; except, in each case, to the extent such Losses result from the gross negligence or willful misconduct of any Licensee Indemnitee or the breach by Licensee of any warranty, representation, covenant or agreement made by
Licensee in this Agreement. 
 13.2 Indemnification by Licensee. Licensee hereby agrees to save, defend and hold POZEN and its
Affiliates and their respective directors, officers, employees and agents (each, an “POZEN Indemnitee”) harmless from and against any and all Losses to which any POZEN Indemnitee may become subject as a result of any claim, demand,
action or other proceeding by any Third Party to the extent such Losses arise directly or indirectly out of: (i) the development, manufacture, use, handling, storage, sale or other disposition of any Product by Licensee, its Affiliates or any
of their respective Sublicensees, (ii) the gross negligence or willful misconduct of any Licensee Indemnitee, or (iii) the breach by Licensee of any warranty, representation, covenant or agreement made by Licensee in this Agreement, in
each case ((i), (ii) and (iii)), after the Amended and Restated Effective Date; except, in each case, to the extent such Losses result from the gross negligence or willful misconduct of any POZEN Indemnitee or the breach by POZEN of any
warranty, representation, covenant or agreement made by POZEN in this Agreement. 
 13.3 Indemnification Procedure. 

13.3.1 Notice of Claim. The indemnified Party will give the indemnifying Party (the “Indemnifying Party”) prompt
written notice (an “Indemnification Claim Notice”) of any Losses or discovery of fact upon which such Indemnified Party intends to base a request for indemnification under Section 13.1 (Indemnification by POZEN) or
Section 13.2 (Indemnification by Licensee); provided, however, that the failure to give such prompt written notice will not relieve Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent
that the Indemnifying Party is actually prejudiced as a result of such failure. In no event will the Indemnifying Party be liable for any Losses that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a
description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss are known at such time). The indemnified Party will furnish promptly to the indemnifying Party copies of all papers and official
documents received in respect of any Losses. All indemnification claims in respect of a Party, its Affiliates or their respective directors, officers, employees and agents (collectively, the “Indemnitees” and each an
“Indemnitee”) will be made solely by such Party to this Agreement (the “Indemnified Party”). 
 13.3.2
Control of Defense. At its option, the Indemnifying Party may assume the defense of any claim for which indemnification is sought (a “Third Party Claim”) by giving written notice to the Indemnified Party within *** (***) days
after the Indemnifying Party’s receipt of an Indemnification Claim Notice. Upon assuming the defense of a Third Party Claim, the Indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any


  
 -34- 









 CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS DOCUMENT. EACH SUCH
PORTION, WHICH HAS BEEN OMITTED HEREIN AND REPLACED WITH AN ASTERISK ***, HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION 
  

 
legal counsel selected by the Indemnifying Party. In the event the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party will immediately deliver to the
Indemnifying Party all original notices and documents (including court papers) received by any Indemnitee in connection with the Third Party Claim. Should the Indemnifying Party assume the defense of a Third Party Claim, the Indemnifying Party will
not be liable to the Indemnified Party or any other Indemnitee for any legal expenses subsequently incurred by such Indemnified Party or other Indemnitee in connection with the analysis, defense or settlement of the Third Party Claim. 

13.3.3 Right to Participate in Defense. Without limiting Section 13.3.2 (Control of Defense) above, any Indemnitee will be entitled to
participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment will be at the Indemnitee’s own expense unless (i) the employment
thereof has been specifically authorized by the Indemnifying Party in writing, or (ii) the Indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 13.3.2 (Control of Defense) (in which case the
Indemnified Party will control the defense). 
 13.3.4 Settlement. With respect to any Losses relating solely to the payment of money
damages in connection with a Third Party Claim and that will not result in the Indemnitee’s becoming subject to injunctive or other relief or otherwise adversely affect the business of the Indemnitee in any manner, and as to which the
Indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnitee hereunder, the Indemnifying Party will have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of
such Loss, on such terms as the Indemnifying Party, in its sole discretion, will deem appropriate, and will transfer to the Indemnified Party all amounts which said Indemnified Party will be liable to pay prior to the time prior to the entry of
judgment. With respect to all other Losses in connection with Third Party Claims, where the Indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 13.3.2 (Control of Defense), the Indemnifying Party will have
authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss provided it obtains the prior written consent of the Indemnified Party (which consent will be at the Indemnified Party’s sole and
absolute discretion). The Indemnifying Party will not be liable for any settlement or other disposition of a Loss by an Indemnitee that is reached without the written consent of the Indemnifying Party. Regardless of whether the Indemnifying Party
chooses to defend or prosecute any Third Party Claim, no Indemnitee will admit any liability with respect to, or settle, compromise or discharge, any Third Party Claim without the prior written consent of the Indemnifying Party. 

13.3.5 Cooperation. The Indemnified Party will, and will cause each other Indemnitee to, cooperate in the defense or prosecution
thereof and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection with the defense or prosecution of
any Third Party Claim. Such cooperation will include access during normal business hours afforded to the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third
Party

Claim, and making Indemnitees and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the
Indemnifying Party will reimburse the Indemnified Party for all its reasonable out-of-pocket expenses in connection therewith. 
 13.4
Expenses. Except as provided above, the reasonable and verifiable costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any claim will be reimbursed on a Calendar Quarter basis by
the Indemnifying Party, without prejudice to the Indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the Indemnifying Party is ultimately held not to be obligated to
indemnify the Indemnified Party. 
 13.5 Insurance. Each Party will have and maintain such types and amounts of liability insurance
as is normal and customary in the industry generally for parties similarly situated, and will upon request provide the other Party with a copy of its policies of insurance in that regard, along with any amendments and revisions thereto. 

 

	14.	LIMITATION OF LIABILITY 

 IN NO EVENT WILL EITHER PARTY BE LIABLE FOR LOST PROFITS, LOSS
OF DATA, OR FOR ANY SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, HOWEVER CAUSED, ON ANY THEORY OF LIABILITY AND WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, ARISING UNDER ANY CAUSE OF ACTION AND
ARISING IN ANY WAY OUT OF THIS AGREEMENT. THE FOREGOING LIMITATIONS WILL NOT APPLY TO AN AWARD OF ENHANCED DAMAGES AVAILABLE UNDER THE PATENT LAWS FOR WILLFUL PATENT INFRINGEMENT AND WILL NOT LIMIT EITHER PARTY’S LIABILITY TO THE OTHER PARTY
UNDER SECTIONS 7.5 (RESTRICTIVE COVENANT), 10.4 (POZEN NON-COMPETE), 11 (CONFIDENTIALITY), AND 13 (INDEMNIFICATION AND INSURANCE) OF THIS AGREEMENT. 
  

	15.	MISCELLANEOUS 

 15.1 Assignment. 

15.1.1 Without the prior written consent of the other Party hereto (which may be granted at the other Party’s discretion), neither
Party will sell, transfer, assign, delegate, pledge or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise, this Agreement or any of its rights or duties hereunder; provided, however, that either Party
hereto may assign or transfer this Agreement or any of its rights or obligations hereunder without the consent of the other Party (a) to any Affiliate of such Party; or (b) in connection with the transfer or sale of all or substantially
all of the business of such party to which this Agreement relates to a Third Party, whether by merger, sale of stock, sale of assets or otherwise. Except as set forth in that certain side letter agreement between POZEN and AstraZeneca AB dated
September 16, 2013, the assigning Party (except if it is not the surviving entity) will remain jointly and severally liable with the relevant Affiliate or Third Party assignee under this Agreement, and the relevant Affiliate assignee, Third
Party assignee or surviving entity will assume in writing all of the assigning Party’s obligations under this Agreement. Any purported assignment or transfer in violation of this Section 15.1 (Assignment) will be void ab initio and
of no force or effect.

 15.1.2 In the event that POZEN desires to sell all or a part of its rights to receive
payments under this Agreement, then upon POZEN’s written request, Licensee shall enter into a consent in substantially the form of the Consent Agreement attached hereto as Schedule 15.1.2 with respect to such transaction. 

15.2 Termination of Certain Rights Upon POZEN Change of Corporate Control. POZEN shall promptly notify Licensee in writing following
consummation of a Change of Corporate Control of POZEN. Notwithstanding anything else in this Agreement to the contrary, in the event of a Change of Corporate Control of POZEN, then Licensee will have the right, exercisable by written notice to
POZEN or its successor in interest given within *** (***) days after Licensee receives written notice from POZEN of the completion of such Change of Corporate Control: (a) to terminate *** established pursuant to this Agreement; and (b) to
terminate its obligation to make *** to POZEN pursuant to this Agreement other than *** and as reasonably required to ***; subject, in each case, to Licensee’s continued compliance with all applicable provisions of this Agreement (including,
without limitation, Articles 8, 9 and 11). POZEN shall cooperate in providing to Licensee all information, assistance, assignments and other support reasonably requested to assist Licensee in assuming such control. For purposes of clarification, all
Confidential Information of Licensee in POZEN’s or its successor’s possession following Licensee’s exercise of its rights under this Section 15.2 shall continue to be subject to all applicable provisions of this Agreement
(including, without limitation, Articles 7 and 11). 
 15.3 Severability. If any provision of this Agreement is held to be illegal,
invalid or unenforceable under any present or future law, and if the rights or obligations of either Party under this Agreement will not be materially and adversely affected thereby, (a) such provision will be fully severable, (b) this
Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this Agreement will remain in full force and effect and will not be affected by
the illegal, invalid or unenforceable provision or by its severance herefrom, and (d) in lieu of such illegal, invalid or unenforceable provision, there will be added automatically as a part of this Agreement a legal, valid and enforceable

CONSENT AGREEMENT 

This Consent Agreement (this “Consent”) is made and entered into as of
[                    ] the Effective Date by and between POZEN Inc., a Delaware corporation (“Sponsor”), and [AstraZeneca AB, a

to receive payments under Sections [8.2, 9.6.4 and 12.6.4(b)(i) of the Agreement and paragraph 5 of that certain letter agreement by and among Sponsor, Counterparty and Horizon Pharma USA dated November     , 2013, as well as
certain related information rights under Sections 8.3 and 8.4 of the Agreement and certain recovery rights under Section 8.5 of the Agreement] [8.1 and 9.6.4 of the Agreement and paragraph 5 of that certain letter agreement by and among
Sponsor, Counterparty and AstraZeneca AB dated November     , 2013, as well as certain related information rights under Sections 8.2 and 8.3 of the Agreement and certain recovery rights under Section 8.4 of the Agreement]
(collectively, “Rights”; such contemplated transaction, the “Transaction”). In connection with the Transaction, Sponsor is requesting Counterparty to give its consent under the Agreement to certain matters, as set
forth below. Capitalized terms not otherwise defined herein shall have the meaning ascribed to them in the Agreement. 
 1.
Assignability. Notwithstanding Section 15.1 of the Agreement, Counterparty hereby consents and agrees that in connection the Transaction, Sponsor may sell, assign, pledge as security, contribute, convey, grant or otherwise transfer
(collectively, “assign”) all or any part of the Rights to any one person or entity (whether or not an affiliate of Sponsor) other than a Competitor without the prior written consent of Counterparty in accordance with the terms of
this Consent. In addition, such person or entity (an “Assignee”) of Sponsor may likewise assign such Assignee’s Rights to any one person or entity (whether or not Sponsor or an affiliate of Sponsor) other than a Competitor
without the prior written consent of Counterparty, it being understood and agreed that, all times, there shall only be one single person or entity that holds the Rights (other than Sponsor) and constitutes an “Assignee.”
“Competitor” shall mean any Person, other than Sponsor or its subsidiaries and affiliates, that is in the business of researching, developing or commercializing therapeutics primarily for rheumatoid arthritis and osteoarthritis pain
indications or any company ranked in the top 10 pharmaceutical companies in the United States based on IMS-reported pharmaceutical sales for the preceding calendar year (or any of such company’s subsidiaries or controlled affiliates). 

2. Payment Direction; Reports. Following the consummation of the Transaction, Sponsor shall remain responsible for the performance of
its obligations and the exercise of its rights under the Agreement, however, Counterparty agrees that, upon written notice from Sponsor (or any direct or indirect permitted Assignee contemplated by Section 1 above),

PORTION, WHICH HAS BEEN OMITTED HEREIN AND REPLACED WITH AN ASTERISK ***, HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION 
  

 
Counterparty shall deliver any future payments contemplated by the Agreement, together with any royalty or other reports or statements contemplated by the Agreement (“Reports”)
to the Assignee, in accordance with the directions in such written notice; provided copies of Reports are also simultaneously sent to the Sponsor. 

3. Prospective Assignee Confidentiality. Notwithstanding Section 11 of the Agreement, Counterparty consents and agrees that

financing parties, insurance providers, investors, lenders, managers, members, officers, partners, sublicensees, trustees or other representatives or any third party that has, or proposes to have, an interest (whether direct or indirect) in the
Rights (each, a “Recipient”), provided that each such Recipient (a) is not a Competitor and (b) shall agree to keep such Confidential Information confidential on reasonable and customary terms pursuant to a non-disclosure
agreement between Sponsor (or an affiliate of Sponsor) and such Recipient, which non-disclosure agreement shall, among other things, provide that (i) if such Recipient is not a prospective Assignee identified by the Company or a holder of a
debt or equity interests therein (a “Prospective Assignee”), the term of such non-disclosure agreement shall extend for a period of 24 months from the date of such nondisclosure agreement, (ii) if such Recipient is a
Prospective Assignee, the term of such non-disclosure agreement shall extend for a period of 24 months from the date such Prospective Assignee notifies Sponsor that it ceases to have an interest in the Transaction, (iii) such Recipient shall
use any Confidential Information so disclosed only to evaluate, enter into, monitor or enforce the Transaction, (iv) upon expiration of such non-disclosure agreement, such Recipient promptly shall destroy the Confidential Information or return
the Confidential Information to Sponsor, as directed by Sponsor, provided that in each case an appropriate person within such Recipient’s organization may retain one copy of such Confidential Information subject to the provisions hereof if
required to comply with internal record retention policies or regulatory considerations, and (v) Counterparty shall be treated as a third party beneficiary of such non-disclosure agreement and shall have the right to enforce any provision of
such non-disclosure agreement against such Recipient. For the avoidance of doubt, the term “Confidential Information” shall include unredacted copies of the Agreement, all royalty reports provided by Counterparty pursuant to Section

definitive documentation for the Transaction, to be bound by confidentiality provisions in substantially the same form and substance as those confidentiality provisions contained in Section 11 of the Agreement (with such Counterparty being
treated as a third party beneficiary of such provisions to the same extent as is contemplated by clause (v) of Paragraph 3 hereof). 

5. Consent Concerning Additional Disclosures. Counterparty hereby consents to and agrees that Sponsor may disclose to its advisors,
including its consulting firm, L.E.K. Consulting (“LEK”), and the Sponsor, its advisors and/or LEK may in turn disclose to Prospective Assignees (who are not Competitors and who have agreed to the confidentiality

 Except as supplemented hereby, all terms and provisions of the Agreement shall remain in full force and effect. This Consent may be
executed in any number of counterparts, each of which shall be deemed an original, and all of which, taken together, shall constitute one and the same agreement. An executed signature page of this Consent delivered by facsimile transmission or in
PDF format via email shall be as effective as an original executed signature page. This Consent shall be governed by the laws of the State of New York without regard to any choice of law principles thereof that would cause the application of the
laws of a different jurisdiction.
