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 applicable rate in respect of any such Payments following the receipt of an Indirect Taxes invoice in the appropriate form issued by the Party receiving Payments in respect of those Payments, such Indirect Taxes to be payable on the due date of the payment of the Payments to which such Indirect Taxes relate.

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

***Confidential Treatment Requested

- 23 -

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.

9.5 Cooperation. Each Party acknowledges the importance of securing and maintaining effective patent protection for the Licensed Technology and Joint Patents. Each Party agrees to cooperate fully in the preparation, filing, prosecution and maintenance of the Licensed 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

***Confidential Treatment Requested

- 24 -

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.

9.6.2 Challenge by Third Parties. Licensee and POZEN will each notify the other Party in writing within […***…] ([…***…]) Business Days of learning of any alleged or threatened opposition, reexamination request, action for declaratory judgment, nullity action, interference or other attack upon the validity, title or enforceability of the Licensed Patents or Joint Patents by a Third Party. […***…] will have the first right, but not the obligation, to defend any such challenge. If […***…] does not commence Diligent Efforts to defend against the alleged or threatened challenge (i) within […***…] ([…***…]) days following the detection of the alleged challenge, or (ii) […***…] ([…***…]) Business Days before the time limit, if any, set forth in appropriate laws and regulations for making a filing in defense of such a challenge, whichever comes 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 […***…];

***Confidential Treatment Requested

- 25 -

and (b) settlements, damages or other monetary awards recovered pursuant to a suit, action or proceeding brought by [...***...] will be […***…].

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 developments in connection with any such claim, suit, or proceeding; provided, that if […***…] is named as a defendant in any such claim, suit or proceeding, that […***…] shall have the right to 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 to participate in the defense of the claims.

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 promptly list and maintain with the applicable

***Confidential Treatment Requested

- 26 -

Regulatory Authorities in the Territory during the Term correct and complete listings of applicable Licensed Patents for such POZEN Product, including all so called “Orange Book” listings required under the Xxxxx-Xxxxxx Act. [...***...].

9.10.2 Xxxxx-Xxxxxx 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 Xxxxx-Xxxxxx 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 notice to POZEN of its decision not to bring suit within […***…] ([…***…]) Business Days after receipt of notice of such certification (or, if the time period permitted by law is less than […***…] ([…***…]) Business Days, within […***…] of the time period permitted by law for 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.

9.11 Patent Marking. Any POZEN Product marketed and sold by Licensee under this Agreement will be marked with appropriate patent numbers or indicia as permitted or required by law. The Parties agree to cooperate to reach a decision on the marking requirements.

POZEN covenants that it will not at any time prior to the expiration of the Royalty Term, and will ensure that its Affiliates do not, directly or indirectly, develop or commercialize or license any Third Party to develop or commercialize any product having a [...***...].

12. TERM AND TERMINATION

12.1 Amended and Restated Effective Date.

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

***Confidential Treatment Requested

- 31 -

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 ninety (90) 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 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 sixty (60) days following such Post-Approval Failure.

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

- 32 -

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 hereby grants to Licensee and all Affiliates of Licensee, effective upon any breach of this Agreement caused by the rejection of this Agreement by POZEN under Section 365 of Title 11 or otherwise, a right of access and to obtain possession of and to benefit from the following items to the extent Controlled by POZEN relating to the Licensed Technology or POZEN Products: (i) copies of research data, (ii) laboratory samples, (iii) formulas, (iv) laboratory notes and notebooks, (v) data and results related to clinical trials, (vi) clinical and pre-clinical research data and results, and (vii) any IND, NDA or other regulatory filing or approval related to a POZEN Product in the Territory, all of which constitute “embodiments” of intellectual property pursuant to Section 365(n) of Title 11, and (viii) copies or examples of all other embodiments of the Licensed Technology. 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

- 33 -

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

- 34 -

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 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

- 36 -

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 […***…]

***Confidential Treatment Requested

[...***...]; 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 provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and reasonably acceptable to the Parties herein. To the fullest extent permitted by Applicable Law, each Party hereby waives any provision of law that would render any provision prohibited or unenforceable in any respect.

15.4 Governing Law; Dispute Resolution.

15.4.1 This Agreement, and any disputes between the Parties related to or arising out of this Agreement, including the Parties’ relationship created hereby, the negotiations for and entry into this Agreement, its conclusion, binding effect, amendment, coverage, termination, or the performance or alleged non-performance of a Party of its obligations under this Agreement (each a “Dispute”), will be governed by the laws of the State of New York without reference to any choice of law principles thereof that would cause the application of the laws of a different jurisdiction.

15.4.2 In the event of any Dispute, a Party may notify the other Party in writing of such Dispute, and the Parties will try to settle such Dispute amicably between themselves. If the Parties are unable to resolve the Dispute within […***…] Business Days of receipt of the written notice by the other Party, such Dispute will be referred to the Chief Executive Officers of each of the Parties (or their respective designees) who will use their good faith efforts to resolve the Dispute within […***…] Business Days after it was referred to the Chief Executive Officers.

15.4.3 Any Dispute that is not resolved as provided in Section 15.4.2, whether before or after termination of this Agreement, will be resolved by litigation in the courts of competent jurisdiction located in New York, New York. Each Party hereby agrees to the exclusive jurisdiction of such courts and waives any objections as to the personal jurisdiction or venue of such courts.

15.4.4 Notwithstanding the foregoing, nothing in this Section 15.4 (Governing Law; Dispute Resolution) will limit either Party’s right to seek immediate temporary injunctive

or other temporary equitable relief whenever the facts or circumstances would permit a Party to seek such relief in a court of competent jurisdiction.

15.6 Entire Agreement; Modifications. This Agreement including the Exhibits attached hereto, each of which is hereby incorporated and made part of in this Agreement by reference, together with that certain side letter between POZEN and AstraZeneca AB, dated

- 39 -

September 16, 2013, and the Three-Party Agreement, sets forth and constitutes the entire agreement and understanding between the Parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, promises and representations, whether written or oral, with respect thereto. Each Party confirms that it is not relying on any representations or warranties of the other Party except as specifically set forth herein. No amendment or modification of this Agreement will be binding upon the Parties unless in writing and duly executed by authorized representatives of both Parties.

15.7 Relationship of the Parties.

Neither Party will have the authority to make any statements, representations or commitments of any kind, or to take any action, which will be binding (or purport to be binding) on the other.

15.8 Waiver. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver will be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. The waiver by either Party hereto of any right hereunder or of claims based on the failure to perform or a breach by the other Party will not be deemed a waiver of any other right hereunder or of any other breach or failure by said other Party whether of a similar nature or otherwise.

15.9 Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument.

15.10 No Benefit to Third Parties. The representations, warranties, covenants and agreements set forth in this Agreement are for the sole benefit of the Parties hereto and their successors and permitted assigns (including Horizon), and they will not be construed as conferring any rights on any Third Party.

Each Party will duly execute and deliver, or cause to be duly executed and delivered, such further instruments and do and cause to be done such further acts and things, including the filing of such assignments, agreements, documents and instruments, as may be necessary or as the other Party may reasonably request in connection with this Agreement or to carry out more effectively the provisions and purposes, or to better assure and confirm unto such other Party its rights and remedies under this Agreement.

15.12 No Drafting Party. This Agreement has been submitted to the scrutiny of, and has been negotiated by, both Parties and their counsel, and will be given a fair and reasonable interpretation in accordance with its terms, without consideration or weight being given to any such terms having been drafted by any Party or its counsel. No rule of strict construction will be applied against either Party.

15.13 Construction. Except where the context otherwise requires, wherever used, the use of any gender will be applicable to all genders and the word “or” is used in the inclusive sense (and/or). The captions of this Agreement are for convenience of reference only and in no

- 40 -

way define, describe, extend or limit the scope or intent of this Agreement or the intent of any provision contained in this Agreement. The term “including” as used herein means including, without limiting the generality of any description preceding such term. Unless the context indicates otherwise, the singular will include the plural and the plural will include the singular. Unless the context requires otherwise, (a) any definition of or reference to any agreement, instrument or other document refer to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein or therein), (b) any reference to any laws refer to such laws as from time to time enacted, repealed or amended, (c) the words “herein”, “hereof” and “hereunder”, and words of similar import, refer to this Agreement in its entirety and not to any particular provision hereof, and (d) all references herein to Sections and Exhibits, unless otherwise specifically provided, refer to the Sections and Exhibits of this Agreement.

15.14 Assignment to Horizon. POZEN acknowledges that, in connection with the Divestiture, AstraZeneca AB will assign this Agreement to Horizon, effective as of the Amended and Restated Effective Date, and that, notwithstanding Section 15.1, AstraZeneca AB may assign this Agreement to Horizon in connection with the Divestiture without the prior written consent of POZEN. Without limiting any provision of the Three-Party Agreement, from and after the Amended and Restated Effective Date, all references to “Licensee” in this Agreement, other than references to Licensee in connection with anticipated actions to be taken by AstraZeneca AB as Licensee in connection with the Divestiture, shall automatically be deemed references to Horizon.

15.15 Amendment and Restatement. This Agreement, together with the ROW Agreement, constitutes an amendment and restatement of the Original Agreement effective from and after the Amended and Restated Effective Date. All rights or obligations owing under the Original Agreement, or based on facts or events occurring or existing prior to the Amended and Restated Effective Date, shall be governed by the Original Agreement. As of the Amended and Restated Effective Date, the Original Agreement is hereby amended, supplemented, modified and restated in its entirety as described herein and in the ROW Agreement. For clarity, in no event shall this Section 15.15 or any other provision in this Agreement be deemed to limit or otherwise affect the agreements made by AstraZeneca AB, Horizon and POZEN in the Three-Party Agreement or that certain side letter agreement between POZEN and AstraZeneca AB dated September 16, 2013 with respect to each party’s respective liability in connection with the Original Agreement, this Agreement or the ROW Agreement.

Form of Consent Agreement

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 corporation organized under the laws of Sweden][Horizon Pharma USA, Inc., a Delaware corporation] (“Counterparty”). Sponsor and Counterparty are parties to the Amended and Restated Collaboration and License Agreement for [Outside] the United States effective as of November         , 2013, and any amendments thereto (collectively, the “Agreement”). As of the Effective Date, Sponsor is considering a transaction to sell all or part of its rights 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), Counterparty shall deliver any future payments contemplated by the Agreement, together with
