All such Pozen Common Shares, when so converted, shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of a certificate (or evidence of shares in book-entry form) that immediately prior to the Merger Effective Time represented any such Pozen Common Shares (each, a “Pozen Certificate”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, including the right to receive, pursuant to Section 2.1(l), cash in lieu of fractional Parent Shares, if any. Notwithstanding the foregoing, if, between the date of this Agreement and the Merger Effective Time, the outstanding Pozen Common Shares or Parent Shares shall have been changed into a different number of shares or a different class, by reason of any stock dividend (including any dividend or distribution of securities convertible into Parent Shares), subdivision, reclassification, recapitalization, split, combination or exchange of shares, or any similar event shall have occurred, then any number or amount contained herein which is based upon the number of Pozen Common Shares or Parent Shares, as the case may be, will be appropriately adjusted to provide to Pozen and the holders of Pozen Common Shares the same economic effect as contemplated by this Agreement prior to such event.

(i) Each Parent Share, as issued and outstanding immediately prior to the Effective Time, shall remain issued and outstanding and shall not be affected by the Merger, except for the Parent Subscriber Share which shall be acquired by Parent immediately following the Effective Time for nil consideration and cancelled.

(j) The exchange of Pozen Certificates shall be effected as follows:

(i) Prior to the Merger Effective Time, Pozen shall appoint a bank or trust company reasonably acceptable to Tribute to act as exchange agent (the “Merger Exchange Agent”) for the delivery of the Merger Consideration. At or prior to the Merger Effective Time, Parent shall issue, fully paid, the Parent Shares to be delivered as Merger Consideration and deposit with the Merger Exchange Agent, for the benefit of the holders of Pozen Certificates, for exchange in accordance with this ARTICLE 2 through the Merger Exchange Agent, the aggregate cash consideration for fractional shares and certificates representing the Parent Shares to be delivered as Merger Consideration (or, if uncertificated Parent Shares will be delivered, Parent shall make appropriate alternative arrangements).

(ii) As promptly as reasonably practicable after the Merger Effective Time (and in any event within four (4) Business Days after the Merger Effective Time), Parent shall cause the Merger Exchange Agent to mail to each holder of record of Pozen Common Shares, a form of letter of transmittal (the “Pozen Letter of Transmittal”) which shall specify that delivery shall be effected, and risk of loss and title to the Pozen Certificates shall pass, only upon delivery of the Pozen Certificates to the Merger Exchange Agent, shall be in such form and have such other provisions (including customary provisions with respect to delivery of an “agent’s message” with respect to shares held in book-entry form) as Pozen may specify acting reasonably, and shall be prepared prior to the Closing, together with instructions thereto.

(iii) Upon (A) in the case of Pozen Common Shares represented by a Pozen Certificate, the surrender of such Pozen Certificate for cancellation to the Merger Exchange Agent or (B) in the case of Pozen Common Shares held in book-entry form, the receipt of an “agent’s message” by the Merger Exchange Agent, in each case together with the Pozen Letter of Transmittal, duly, completely and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Merger Exchange Agent, the holder of such Pozen Common Shares shall be entitled to receive in exchange therefor the Merger Consideration into which such Pozen Common Shares have been converted pursuant to Section 2.1(h) (after taking into account all Pozen Common Shares then held by such holder). In the event of a transfer of ownership of Pozen Common Shares that is not registered in the transfer records of Pozen, the applicable Merger Consideration may be delivered to a transferee, if the Pozen Certificate representing such Pozen Common Share (or, if such Pozen Common Share is held in book-entry form, proper evidence of such transfer) is presented to the Merger Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer Taxes have been paid. Until surrendered as contemplated by this Section 2.1(j), each Pozen Common Share or, and any Pozen Certificate with respect thereto, shall be deemed at any time from and after the Merger Effective Time to represent only the right to receive, upon such surrender, the Merger Consideration that the holders of Pozen Common Shares are entitled to receive in respect of such shares pursuant to Section 2.1(h) (after taking into account all Pozen Common Shares then held by such holder).

(iv) The Merger Consideration delivered and credited as fully paid in accordance with the terms of this ARTICLE 2, upon conversion of any Pozen Common Shares, shall be deemed to have been delivered and paid in full satisfaction of all rights pertaining to such Pozen Common Shares, as applicable. From and after the Merger Effective Time, there shall be no further registration of transfers on the stock transfer books of the US Surviving Company of Pozen Common Shares that were outstanding immediately prior to the Merger Effective Time. If, after the Merger Effective Time, any Pozen Certificates formerly representing Pozen Common Shares (or Pozen Common Shares held in book-entry form) are presented to the US Surviving Company or the Merger Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this ARTICLE 2.

(v) Any portion of the Merger Consideration that remains undistributed to the holders of Pozen Common Shares for one (1) year after the Merger Effective Time shall be delivered to Parent or its designee, and any holder of Pozen Common Shares who has not theretofore complied with this ARTICLE 2 shall thereafter look only to Parent for its claim for the Merger Consideration deliverable in respect thereof.

(vi) None of Parent, US Merger Sub, Pozen or the Merger Exchange Agent or any of their respective Affiliates shall be liable to any Person in respect of any portion of the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(k) Each of Parent and the Merger Exchange Agent (without duplication) shall be entitled to deduct and withhold from the consideration otherwise payable to any holder of Pozen Common Shares pursuant to this Agreement such amounts as are required to be deducted and withheld with respect to the making of such payment under applicable Laws. Amounts so withheld and paid over to the appropriate taxing authority shall be treated as having been paid to the holder of Pozen Common Shares in respect of which such deduction or withholding was made.

(l) Notwithstanding any other provision of this Agreement, no fractional Parent Shares will be issued and any entitlement to Parent Shares for which fractional Parent Share would be issuable but for this Section 2.1(l) shall be rounded down to the nearest whole Parent Share.

(m) If any Pozen Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Pozen Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond, in such reasonable and customary amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Pozen Certificate, the Merger Exchange Agent shall, in exchange for such lost, stolen or destroyed Pozen Certificate, issue the Merger Consideration deliverable in respect thereof pursuant to this Agreement.

(n) As soon as practicable following the date of this Agreement and, in any event, prior to the Closing Date, the Pozen Board of Directors or an appropriate committee thereof shall adopt such resolutions or take such other actions, if any, as may be required to effect and/or procure the following treatment:

(i) Except for the Pozen Options held by New Pozen Employees and the Performance-Based Option, each Pozen Option that is unvested and outstanding as of immediately prior to the Merger Effective Time, shall, as of immediately prior to the Merger Effective Time, become vested and exercisable. At the Merger Effective Time, each outstanding Pozen Option shall be assumed by Parent. Each Pozen Option so assumed by Parent under this Agreement will continue to have, and be subject to, the same terms and conditions of such options immediately prior to the Merger Effective Time (including, without limitation, any repurchase rights) except that (i) each Pozen Option will be solely exercisable (or will become exercisable in accordance with its terms) for that number of whole Parent Shares equal to the number of Pozen Shares that were issuable upon exercise of such Pozen Option immediately prior to the Merger Effective Time, and (ii) the per share exercise price for the Parent Shares issuable upon exercise of such assumed Pozen Option will be equal to the exercise price per Pozen Share at which such Pozen Option was exercisable immediately prior to the Merger Effective Time. Parent shall take all corporate actions necessary to reserve for issuance a sufficient number of shares of Parent Shares for delivery upon exercise of all Pozen Options pursuant to the terms set forth in this Section 2.1(n)(i). Prior to the Merger Effective Time, Pozen shall take all actions necessary to effect the transactions contemplated by this Section 2.1(n)(i).

(ii) Except for Pozen Common Shares subject to vesting or other lapse restrictions pursuant to the Pozen Share Plan (a “Restricted Pozen Share”) held by New Pozen Employees, each Restricted Pozen Share issued and outstanding immediately prior to the Merger Effective Time shall, as of immediately prior to the Merger Effective Time, be cancelled, and each holder of a Restricted Pozen Share so cancelled pursuant to this Section 2.1(n)(ii) shall become entitled to receive one (1) Parent Share for each such Pozen Share that was issuable upon vesting of such Restricted Pozen Shares immediately prior to the Merger Effective Time, less applicable withholding taxes.

(iii) Except for the Pozen restricted stock unit awards held by New Pozen Employees, each stock-based award (including any restricted stock unit and deferred stock unit awards), other than a Pozen Option or Restricted Pozen Share (“Other Pozen Stock-Based Awards” and together with Restricted Pozen Shares, the “Pozen Share Awards”), that is outstanding immediately prior to the Merger Effective Time, shall, whether vested or unvested, as of immediately prior to the Merger Effective Time, become vested and shall entitle each holder of an Other Pozen Share-Based Award to receive one (1) Pozen Common Share, less applicable withholding Taxes, if any, immediately prior to the Merger Effective Time, which shall converted into Merger Consideration pursuant to Section 2.1(h) except with respect to Other Pozen Stock-Based Awards subject to and not exempt from Section 409A of the Code (the “Section 409A XXXx”). Each New Pozen Employee and any individual holding Section 409A XXXx xxxll receive comparable Parent restricted stock unit awards of equal value and vesting on the basis of one Parent restricted stock unit for each Pozen restricted stock unit held immediately prior to the Merger Effective Time.

(iv) The amounts payable pursuant to this Section 2.1(n) to any current or former employee of Pozen or any of its Affiliates shall be paid through Pozen’s (or its applicable Subsidiary’s) payroll on the next regularly scheduled payment date that occurs not less than three (3) Business Days following the Closing Date. Parent, Pozen and each of their applicable Subsidiaries shall be entitled to deduct and withhold from any consideration otherwise payable to any holder of Pozen Options or Pozen Share Awards, such amounts as Pozen and any applicable Subsidiary are required to deduct and withhold with respect to such payment under applicable Law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereunder as having been paid to the holder of the Pozen Options or Pozen Share Awards in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority. To the extent that the amount so required or permitted to be deducted or withheld from any payment to a holder exceeds the cash component of the consideration otherwise payable to the holder, Pozen and its applicable Subsidiary are hereby authorized to sell or otherwise dispose of such portion of the consideration otherwise payable to the holder as is necessary to provide sufficient funds to Pozen and its applicable Subsidiary to enable it to comply with such deduction or withholding requirement, and Pozen or the applicable Subsidiary shall notify the holder thereof and remit the applicable portion of the net proceeds of such sale to the appropriate taxing authority, and shall remit to such holder any unapplied balance of the proceeds of such sale. The amounts payable pursuant to this Section 2.1(n) to any person, other than a current or former employee of Pozen or any of its Affiliates, shall be paid by Parent or any affiliate of Parent (including Pozen and its Subsidiaries) within ten (10) Business Days following the Closing Date.

(o) It is the intent of the Parties hereto that the treatment of Pozen Share Awards and Pozen Options contemplated herein be in a manner that is consistent with the requirements of Sections 422, 424 and 409A of the Code, including all guidance and regulations issued thereunder.

(p) Parent shall procure that no stamp duty shall be payable by the Pozen Stockholders in connection with the issue to the Pozen Stockholders of the Parent Shares as part of the Merger Consideration.

In addition, Tribute will not object to legal counsel to Pozen making such submissions on the hearing of the application for the Interim Order and the application for the Final Order as such counsel considers appropriate, acting reasonably, provided that Tribute or its legal counsel is advised of the nature of any submissions prior to the hearing and such submissions are consistent with this Agreement and the Plan of Arrangement. Tribute will also provide legal counsel to Pozen on a timely basis with copies of any notice of appearance and evidence or other documents served on Tribute or its legal counsel in respect of the application for the Interim Order or the Final Order or any appeal therefrom and of any notice, whether or not in writing, received by Tribute or its legal counsel indicating any intention to oppose the granting of the Interim Order or the Final Order or to appeal the Interim Order or the Final Order.

(j) The Tribute Options, the Tribute Warrants, the Tribute Compensation Options and the Tribute Stock Option Plan shall be treated as contemplated by, and in the manner set forth in, the Plan of Arrangement.

(k) The Arrangement shall be structured and executed such that the issuance of the Parent Shares to Tribute Shareholders in exchange for their Tribute Common Shares and the issuance of Parent Options to Tribute Optionholders in exchange for their Tribute Options, all pursuant to the Arrangement, will not require registration under the 1933 Securities Act in reliance upon Section 3(a)(10) thereof. Each of the Parties agrees to act in good faith, consistent with the intent of the Parties and the intended treatment of the Arrangement as set forth in this Section 2.2.

(l) Tribute and Pozen agree to cooperate in the preparation of presentations, if any, to Tribute Shareholders or other securityholders regarding the Arrangement, and Tribute agrees to consult with Pozen in connection with any communication or meeting with Tribute Shareholders or other securityholders that it may have, provided, however, that the foregoing shall be subject to Tribute’s overriding obligations to make any disclosure or filing required by applicable Laws or stock exchange rules and, if Tribute is required to make any such disclosure, it shall use its commercially reasonable efforts to give Pozen a reasonable opportunity to review and comment thereon prior to its dissemination.

2.5 Pozen Stockholder Meeting

(a) Pozen shall duly take all lawful action to call, give notice of, convene and hold the Pozen Meeting in accordance with the constituent documents of Pozen and applicable Law as promptly as practicable following the date upon which the Form S-4 becomes effective and the Pozen Proxy Statement has been cleared by the SEC for the purpose of obtaining Pozen Stockholder Approval as required by the DGCL and this Agreement.

(b) Subject to the terms of this Agreement, unless Pozen shall have effected a Pozen Change of Recommendation in accordance with the terms of this Agreement, Pozen shall use its commercially reasonable efforts to solicit from Pozen Stockholders proxies in favor of the Pozen Stockholder Approval and take all other actions that are reasonably necessary or desirable to obtain the approval of the Merger and the adoption of this Agreement by Pozen Stockholders, including using the services of proxy solicitation agents, and take all other actions reasonably requested by Tribute that are reasonably necessary to obtain Pozen Stockholder Approval and permit Tribute to assist, and consult with Tribute and keep Tribute apprised, with respect to such solicitation and other actions. Unless this Agreement has been terminated in accordance with ARTICLE 7, subject to Section 2.5(a), this Agreement shall be submitted to Pozen Stockholders at the Pozen Meeting for the purpose of obtaining Pozen Stockholder Approval, and nothing contained herein shall be deemed to relieve Pozen of such obligation.

There are no outstanding bonds, debentures or other evidences of indebtedness of Pozen or any of Pozen’s Subsidiaries having the right to vote (or that are convertible into or exchangeable or exercisable for securities having the right to vote) with the holders of Pozen Common Shares on any matter. Section 3.1(e) of the Pozen Disclosure Letter sets out a true, complete and correct list of all Pozen Options and Pozen Share Awards, the names of the holders of such awards, the type of such award, whether each such holder is a current director of Pozen or current employee of Pozen or any of its Subsidiaries and the grant date and the exercise price (as applicable). A true, correct and complete copy of the Pozen Share Plan has been provided or otherwise made available to Parent and Tribute.

(f) Pozen Subsidiaries. Section 3.1(f) of the Pozen Disclosure Letter sets forth a true, complete and correct list of each of the Pozen Subsidiaries, its jurisdiction and form of organization.

Neither Pozen nor any of the Pozen Subsidiaries own any interest or investment (whether equity or debt) in any other Person, other than a Pozen Subsidiary, which interest or investment is material to Pozen and the Pozen Subsidiaries, taken as a whole.

(g) Securities Laws Matters.

(i) The Pozen Common Shares are registered pursuant to Section 12(b) of the 1934 Exchange Act and listed on NASDAQ. Neither the SEC nor any state regulatory authority has issued any order preventing or suspending trading of any securities of Pozen, and Pozen is in compliance in all material respects with applicable U.S. Securities Laws.

(ii) Pozen is in compliance in all material respects with the requirements of the U.S. Securities Laws and NASDAQ for continued listing of the Pozen Common Shares thereon. Except for the transactions contemplated by this Agreement, Pozen has not taken any action designed to terminate, or likely to have the effect of terminating, the registration of the Pozen Common Shares under the 1934 Exchange Act or the listing of such shares on NASDAQ.

(iii) Trading in Pozen Common Shares on NASDAQ is not currently halted or suspended. No delisting, suspension of trading or cease trading order with respect to any securities of Pozen is pending or, to the knowledge of Pozen, threatened.

(vi) None of the documents in the Pozen Public Disclosure Record, as of their respective dates (and, if amended or superseded by a filing prior to the date hereof, then on the date of such filing), contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(h) Financial Statements.

(i) The Pozen Financial Statements have been prepared in accordance with U.S. GAAP applied on a basis consistent with those of previous periods and in accordance with applicable Laws, except as otherwise stated in the notes to such statements or in the auditor’s report thereon and subject, in the case of the Pozen Interim Financial Statements, to normal year-end audit adjustments, which are not material to Pozen and the Pozen Subsidiaries, taken as a whole, individually or in the aggregate, and may omit notes which are not material and are not required by applicable Laws or U.S. GAAP. The Pozen Financial Statements present fairly, in all material respects, the consolidated balance sheets and consolidated statements of operations, consolidated statements of stockholders’ equity and consolidated statements of cash flows of Pozen and the Pozen Subsidiaries as of the respective dates thereof and for the respective periods set forth therein. There are no outstanding loans made by Pozen or any of the Pozen Subsidiaries to any director or officer of Pozen. All of such documents in the Pozen Public Disclosure Record (including any financial statements included or incorporated by reference therein), as of their respective dates (and as of the date of any amendment to the respective document in the Pozen Public Disclosure Record), complied as to form in all material respects with the applicable requirements of the 1933 Securities Act and the 0000 Xxxxxxxx Xxx.

(ii) Pozen has designed such disclosure controls and procedures, or caused them to be designed under the supervision of its Chief Executive Officer and Chief Financial Officer, to provide reasonable assurance that material information relating to Pozen is made known to its Chief Executive Officer and Chief Financial Officer by others within Pozen and the Pozen Subsidiaries.

(iii) Pozen has designed such internal controls over financial reporting, or caused them to be designed under the supervision of the Chief Executive Officer and Chief Financial Officer of Pozen, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP. To the knowledge of Pozen, since December 31, 2012: (A) except as set forth on Section 3.1(h)(iii) of the Pozen Disclosure Letter, there have been no significant deficiencies in the design or operation of, or material weaknesses in, the internal controls over financial reporting of Pozen that are reasonably likely to adversely affect Pozen’s ability to record, process, summarize and report financial information, and (B) there is and has been no fraud, whether or not material, involving management or any other employees who have a significant role in the internal control over financial reporting of Pozen. To the knowledge of Pozen, since December 31, 2012, Pozen has received no (x) written complaints from any source regarding accounting, internal accounting controls or auditing matters or (y) written reports from employees of Pozen regarding questionable accounting or auditing matters.

(i) No Undisclosed Liabilities. Except as set forth in Section 3.1(i) of the Pozen Disclosure Letter, Pozen and the Pozen Subsidiaries have no liability or obligation of any nature (whether accrued, absolute, contingent or otherwise) that would be required to be disclosed on a balance sheet (or the footnotes thereto) prepared in accordance with U.S. GAAP, other than (i) liabilities and obligations disclosed in the Pozen Public Disclosure Record, (ii) liabilities and obligations incurred in the ordinary course of business (other than those specifically disclosed in the Pozen Public Disclosure Record) that would not reasonably be expected to be material to Pozen and its Subsidiaries, taken as a whole (other than those disclosed in the Pozen Public Disclosure Record), (iii) liabilities under Contracts (other than any such liability resulting from a breach or default thereunder) and (iv) liabilities and obligations incurred in connection with this Agreement and the transactions contemplated by this Agreement.

(j) Absence of Certain Changes. From the date of the most recent Pozen Annual Financial Statements to the date of this Agreement, (i) no result, fact, change, effect, event, circumstance, occurrence or development has occurred or arisen which has had or would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on Pozen and (ii) Pozen and each of the Pozen Subsidiaries has conducted its business in all material respects in the ordinary course of business consistent with past practice.

(k) Compliance with Laws. Since December 31, 2012, the business of Pozen and of each of the Pozen Subsidiaries has been and is currently being conducted in material compliance with all applicable Laws, Orders and Regulatory Guidelines and policies and neither Pozen nor any Pozen Subsidiary has received any written notice of any alleged material non-compliance or violation of any such Laws, Orders or Regulatory Guidelines. Neither Pozen nor any of the Pozen Subsidiaries has taken or committed to take any action which would cause Pozen or any of the Pozen Subsidiaries to be in violation of the United States Foreign Corrupt Practices Act or any applicable Laws of similar effect, and, to the knowledge of Pozen, no such action has been taken by any Person acting on behalf of Pozen or any of the Pozen Subsidiaries.

Neither Pozen nor any of the Pozen Subsidiaries nor any of their respective properties or assets is subject to any outstanding Order that would reasonably be expected to prevent or significantly impede or materially delay the completion of the Merger or the Arrangement or have a Material Adverse Effect on Pozen.

(ii) Tribute has designed such disclosure controls and procedures, or caused them to be designed under the supervision of its Chief Executive Officer and Chief Financial Officer, to provide reasonable assurance that material information relating to Tribute is made known to its Chief Executive Officer and Chief Financial Officer by others within Tribute and the Tribute Subsidiaries.

To the knowledge of Tribute, since December 31, 2012: (A) except as set forth on Section 3.2(h)(iii) of the Tribute Disclosure Letter, there have been no significant deficiencies in the design or operation of, or material weaknesses in, the internal controls over financial reporting of Tribute that are reasonably likely to adversely affect Tribute’s ability to record, process, summarize and report financial information, and (B) there is and has been no fraud, whether or not material, involving management or any other employees who have a significant role in the internal control over financial reporting of Tribute.

5.6 Indemnification and Insurance

(a) Each of Tribute, Pozen and their respective Subsidiaries agrees that all rights to indemnification or exculpation now existing in favor of the present and former directors and officers of Tribute, Pozen and their respective Subsidiaries (each such present or former director or officer of Tribute, Pozen or their respective Subsidiaries being referred to as an “Indemnified Party” and such Persons collectively being referred to as the “Indemnified Parties”) as provided in the constituent documents of Tribute, Pozen or any of their respective Subsidiaries or any Contract by which Tribute, Pozen or any of their respective Subsidiaries is bound and which is in effect as of the date hereof, will survive the completion of the Merger and the Arrangement and continue in full force and effect and without modification, with respect to actions or omissions of the Indemnified Parties occurring prior to the Closing.

(b) Without limiting the foregoing, from and after the Merger Effective Time for not less than six (6) years from the Closing Date, each of Parent, US Surviving Company and Tribute shall, jointly and severally, to the fullest extent permitted under applicable Law, indemnify, defend and hold harmless each Indemnified Party against any costs or expenses (including advancing reasonable attorneys’ fees and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by applicable Law, subject to the indemnifying or advancing party’s receipt of an unsecured undertaking by or on behalf of the Indemnified Party to repay such funds if it is ultimately determined in a final and non-appealable judgment of a court of competent jurisdiction that such Indemnified Party is not entitled to indemnification hereunder), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any Proceeding arising out of, relating to or in connection with any action or omission occurring or alleged to have occurred on or prior to the Closing Date, whether asserted or claimed before or after the Merger Effective Time, in connection with or as a result of such Indemnified Party serving as an officer or director of Tribute, Pozen or any of their respective Subsidiaries.

(c) Parent shall, or shall cause its Subsidiaries to, maintain in effect, without any reduction in scope or coverage for six (6) years from the Closing Date, customary policies of directors’ and officers’ liability insurance providing protection no less favorable to the protection provided by the policies maintained by Tribute, Pozen or any of their respective Subsidiaries that are in effect immediately prior to the Closing Date and providing protection in respect of claims arising from facts or events which occurred on or prior to the Closing Date; provided, however, that Parent may, prior to the Closing Date, purchase pre-paid non-cancellable run-off directors’ and officers’ liability insurance on terms substantially similar to the directors’ and officers’ liability policies currently maintained by Tribute, Pozen or any of their respective Subsidiaries, but providing coverage for a period of six (6) years from the Closing Date with respect to claims arising from or related to facts or events which occurred on or prior to the Closing Date; provided, further, however, that in no event shall Parent be required to spend premiums for any of the insurance referenced in this Section 5.6(c) to the extent it would exceed three hundred percent (300%) of Tribute, Pozen or any of their respective Subsidiaries’ current annual premium for directors’ and officers’ liability insurance, in which case Parent shall purchase the maximum amount of insurance available up to the foregoing premium limit.

(d) If Tribute, Pozen or any of their respective Subsidiaries or any of their successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, Parent shall ensure that any such successor or assign assumes all of the obligations set forth in this Section 5.6.

(e) The obligations of Parent and its Subsidiaries under this Section 5.6 shall survive the consummation of the Arrangement and the Merger and shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party to whom this Section 5.6 applies, without the written consent of such affected Indemnified Party (it being expressly agreed that the Indemnified Parties to whom this Section 5.6 applies and their respective heirs, executors, administrators and other legal representatives shall be third party beneficiaries of this Section 5.6, each of whom may enforce the provisions of this Section 5.6). Parent shall pay all expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Party in connection with their enforcement of their rights provided in this Section 5.6; provided that such Indemnified Party prevails in such enforcement action.

(f) The provisions of this Section 5.6 are intended to be in addition to the rights otherwise available to the current and former officers and directors of Tribute, Pozen or any of their respective Subsidiaries by law, charter, statute, by-law or agreement.

5.7 Rule 16b-3 Actions

Prior to the Closing, Tribute, Parent and Pozen shall take all such steps as may be required to cause (a) any dispositions of Pozen Common Shares (including derivative securities with respect to Pozen Common Shares) resulting from the Merger and the other transactions contemplated by this Agreement by each individual who will be subject to the reporting requirements of Section 16(a) of the 1934 Exchange Act with respect to Pozen immediately prior to the Merger Effective Time to be exempt under Rule 16b-3 promulgated under the 1934 Exchange Act and (b) any acquisitions of Parent Shares (including derivative securities with respect to Parent Shares) resulting from the Merger and the other transactions contemplated by this Agreement, by each individual who may become or is reasonably expected to become subject to the reporting requirements of Section 16(a) of the 1934 Exchange Act with respect to Parent, to be exempt under Rule 16b-3 promulgated under the 1934 Exchange Act.

At Tribute’s request, Pozen shall reasonably cooperate with Tribute in good faith and take such actions as Tribute may reasonably request to purchase, at Tribute’s cost and expense and effective as of the Closing, “tail” insurance coverage to the product liabilities insurance of Pozen and its Subsidiaries, for the period specified by Tribute and on such other terms and conditions as Tribute may direct. At Pozen’s request, Tribute shall reasonably cooperate with Pozen in good faith and take such actions as Pozen may reasonably request to purchase, at Pozen’s cost and expense and effective as of the Closing, “tail” insurance coverage to the product liabilities insurance of Tribute and its Subsidiaries, for the period specified by Pozen and on such other terms and conditions as Pozen may direct.

(i) initiate, solicit, knowingly facilitate or knowingly encourage (including by way of furnishing or affording access to information), or take any other action that would be reasonably expected to promote, directly or indirectly, any inquiries or the making of any proposal or offer with respect to a Pozen Acquisition Proposal or potential Pozen Acquisition Proposal;

(ii) participate or engage in any discussions or negotiations regarding, or provide any information with respect to, or otherwise cooperate in any way with, or assist or participate in, knowingly encourage or otherwise knowingly facilitate, any effort or attempt by any other Person (other than Tribute and its Affiliates) to make or complete a Pozen Acquisition Proposal;

(iii) effect any Pozen Change of Recommendation;

(iv) approve, recommend or remain neutral with respect to, or publicly propose to approve, recommend or remain neutral with respect to any Pozen Acquisition Proposal (it being understood that publicly taking no position or a neutral position with respect to a Pozen Acquisition Proposal until the fifth (5^th) Business Day after such Pozen Acquisition Proposal has been publicly announced shall not constitute a violation of this Section 6.1(a)); or

(v) accept or enter into, or publicly propose to accept or enter into, any Pozen Acquisition Agreement.

(b) Pozen shall, and shall cause the Pozen Subsidiaries and each of its and their respective Representatives to, immediately upon execution of this Agreement cease and cause to be terminated any solicitation, encouragement, discussion or negotiation with or involving any Person (other than Tribute and its Affiliates) conducted heretofore by Pozen or the Pozen Subsidiaries, or any of its or their respective Representatives, with respect to any Pozen Acquisition Proposal or which could reasonably be expected to lead to a Pozen Acquisition Proposal and, in connection therewith, Pozen will immediately discontinue access by any Person (other than Tribute and its Affiliates) to any data room (virtual or otherwise) established by Pozen or its Representatives for such purpose.

Within ten (10) Business Days from the date hereof, Pozen shall request the return or destruction of all confidential non-public information provided to any third parties who have entered into a confidentiality agreement with Pozen since December 31, 2013 relating to any potential Pozen Acquisition Proposal and shall use commercially reasonable efforts to ensure that such requests are honored in accordance with the terms of such confidentiality agreements.

Such notice shall include the identity of the Person making such Pozen Acquisition Proposal or proposal, inquiry, offer or request and a description of the material terms and conditions of such Pozen Acquisition Proposal or proposal, inquiry, offer or request, including a copy of any written materials submitted to Pozen, any of the Pozen Subsidiaries or their Representatives.

(d) Notwithstanding Section 6.1(a) or any other provision of this Agreement to the contrary, following receipt by Pozen of any proposal, inquiry, offer or request (or any amendment thereto) that is not a Pozen Acquisition Proposal but which Pozen reasonably believes could lead to a Pozen Acquisition Proposal, Pozen may respond to the proponent to advise it that Pozen can only enter into discussions or negotiations with a party in accordance with this Agreement.

(e) Notwithstanding Section 6.1(a) or any other provision of this Agreement to the contrary, if after the date hereof and before the receipt of the Pozen Stockholder Approval, Pozen or any of the Pozen Subsidiaries, or any of its or their respective Representatives, receives a written Pozen Acquisition Proposal (including, an amendment, change or modification to a Pozen Acquisition Proposal made prior to the date hereof) that was not solicited after the date hereof in contravention of this Section 6.1, Pozen and its Representatives may:

(i) contact the Person making such Pozen Acquisition Proposal and its Representatives solely for the purpose of clarifying the terms and conditions of such Pozen Acquisition Proposal and the likelihood of its consummation, so as to determine whether such Pozen Acquisition Proposal is, or could reasonably be expected to lead to, a Pozen Superior Proposal; and

(ii) if the Pozen Board of Directors determines in good faith, after consultation with its outside legal counsel and financial advisors, that such Pozen Acquisition Proposal is, or could reasonably be expected to lead to, a Pozen Superior Proposal and that the failure to take relevant action would conflict with its fiduciary duties:

(A) furnish information with respect to Pozen and the Pozen Subsidiaries to the Person making such Pozen Acquisition Proposal and its Representatives; provided that (I) Pozen first enters into a confidentiality agreement with such Person that is no less favorable (including with respect to any “standstill” and similar provisions) to Pozen than the Non-Disclosure Agreement, and sends a copy of such agreement to Tribute promptly following its execution, and (II) Pozen contemporaneously provides to Tribute any non-public information concerning Pozen and its Subsidiaries that is provided to such Person which was not previously provided to Tribute or its Representatives; and

(ii) the Pozen Board of Directors has determined in good faith, after consultation with its outside legal counsel and financial advisors, that the failure to take the action specified in Section 6.2(a)(1) or Section 6.2(a)(2), as applicable, would be reasonably likely to be inconsistent with its fiduciary duties to the Pozen Stockholders under applicable Laws;

(iii) Pozen has (A) delivered a Pozen Change of Recommendation Notice to Tribute and (B) in the case of Section 6.2(a)(2) and provided Tribute with a copy of the document(s) containing such Pozen Acquisition Proposal; and

(ii) calling and/or holding a meeting of the Pozen Stockholders requisitioned by the Pozen Stockholders in accordance with the DGCL or taking any other action with respect to a Pozen Acquisition Proposal to the extent ordered or otherwise mandated by a court of competent jurisdiction in accordance with applicable Laws; provided that, subject to the other terms set forth in this Section 6.2, any proxy statement or other document required in connection with such meeting recommends that the Pozen Stockholders vote against any proposed resolution in favor of or necessary to complete such Pozen Acquisition Proposal.

(d) Pozen shall ensure that each of its Subsidiaries, and each of its and their respective Representatives, is aware of the provisions of Section 6.1 and this Section 6.2 and Pozen shall be responsible for any breach of Section 6.1 or this Section 6.2 by such Persons.

If a Tribute Termination Fee Event occurs, Tribute shall pay to Pozen a termination fee of $3,500,000 (the “Tribute Termination Fee”) by wire transfer in immediately available funds to an account specified by Pozen. The Pozen Termination Fee shall be payable at the time specified in Section 7.2(b). The Tribute Termination Fee shall be payable at the time specified in Section 7.2(c).

(ii) the termination of this Agreement by Tribute pursuant to Section 7.1(d)(i) or 7.1(d)(v), in which case the Pozen Termination Fee shall be paid by Pozen within two (2) Business Days of the Pozen Termination Fee Event; or

(iii) the termination of this Agreement by either Tribute or Pozen pursuant to Section 7.1(b)(i) or Section 7.1(b)(ii) or by Tribute pursuant to Section 7.1(d)(iii) (solely as it relates to Section 6.1), if, in any of the foregoing cases, (x) prior to such termination, a Pozen Acquisition Proposal shall have been made public or proposed publicly to Pozen or Pozen Stockholders and has not been publicly withdrawn prior to the Pozen Meeting and (y) within twelve (12) months following such termination, Pozen or one or more of Pozen’s Subsidiaries shall have executed a Pozen Acquisition Agreement and the transactions thereby are at any time subsequently consummated in respect of such Pozen Acquisition Proposal, in which cases the Pozen Termination Fee shall be paid by Pozen on the date of consummation of such transaction; provided that, for purposes of this Section 7.2(b)(iii), the term “Pozen Acquisition Proposal” shall have the meaning assigned to such term in Section 1.1, except that all references to “twenty percent (20%)” therein shall be deemed to be references to “fifty percent (50%).”

(i) the termination of this Agreement by Tribute pursuant to Section 7.1(d)(ii), in which case the Tribute Termination Fee shall be paid by Tribute concurrent with the Tribute Termination Fee Event;

(ii) the termination of this Agreement by Pozen pursuant to Section 7.1(c)(i), in which case the Tribute Termination Fee shall be paid by Tribute within two (2) Business Days of the Tribute Termination Fee Event; or

(d) Each Party acknowledges that the payment of the Termination Fee pursuant to this Section 7.2 represents a payment of liquidated damages which are a genuine pre-estimate of the damages which Tribute or Pozen, as applicable, will suffer or incur as a result of the event giving rise to such payment and are not penalties. Pozen and Tribute irrevocably waive any right that it may have to raise as a defense that any such liquidated damages are excessive or punitive. The Parties agree that the payment of the Termination Fee pursuant to this Section 7.2 in the manner provided herein is the sole and exclusive remedy of Tribute or Pozen, as applicable, in respect of the event giving rise to such payment; provided, however, that nothing contained in this Section 7.2, and no payment of the Termination Fee, shall relieve or have the effect of relieving a Party in any way from liability for damages incurred or suffered by the other Party as a result of an intentional or willful breach of this Agreement.

(e) Notwithstanding any other provision in this Agreement, in no event shall either Party be required to pay the Termination Fee more than once.

(b) “Reduced Pozen Termination Fee Event” means the termination of this Agreement by Pozen pursuant to Section 7.1(c)(iv), in which case the Reduced Pozen Termination Fee shall be paid by Pozen to Tribute within two (2) Business Days of the Pozen Termination Fee Event.

(c) Notwithstanding any other provision in this Agreement, in no event shall either Party be required to pay the Reduced Termination Fee more than once.

7.4 Effect of Termination

If this Agreement is terminated pursuant to and in accordance with this Article 7 (including payment of the Termination Fee, if applicable), it will become void and of no further force and effect, with no liability on the part of any Party to any other Party, except that (a) nothing shall relieve any Party of any liability or obligations arising from any intentional or willful breach by any Party of any of its covenants and agreements contained in this Agreement, and (b) the terms set forth in last paragraph of Section 7.2, Section 7.3, this Section 7.3 and Article 9 (and any related definitions contained in any such Sections or Article), as well as the Non-Disclosure Agreement, shall survive any termination of this Agreement.

Notwithstanding anything contained herein to the contrary, except as otherwise expressly required pursuant to this Agreement (other than this Section 9.5), neither Tribute nor Pozen shall have any obligation to obtain the consent of or consult with the other Party prior to any press release, public statement, disclosure or filing with regard to any Pozen Acquisition Proposal, Tribute Acquisition Proposal, Pozen Change of Recommendation or Tribute Change of Recommendation or in connection with any dispute (including initiation of litigation or similar proceedings) between the Parties.

9.6 Governing Law; Attornment; Service of Process; Waiver of Jury

(a) This Agreement, and any dispute arising out of, relating to, or in connection with this Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware of any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware, except that the approval and effectiveness of the Arrangement shall be governed by the OBCA. Each of the Parties (i) consents to submit itself to the personal jurisdiction of the Court of Chancery of the State of Delaware (the “Chancery Court”) or, if, but only if, the Chancery Court lacks subject matter jurisdiction, any federal court located in the State of Delaware with respect to any dispute arising out of, relating to or in connection with this Agreement or any transaction contemplated hereby, (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court and (iii) agrees that it will not bring any action arising out of, relating to or in connection with this Agreement or any transaction contemplated by this Agreement, in any court other than any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in the Chancery Court or, if, but only if, the Chancery Court lacks subject matter jurisdiction, in any federal court located in the State of Delaware, and hereby further irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

(b) Each Party hereby agrees that any service of process, summons, notice or document by registered mail addressed to such Person at its address set forth in Section 9.1 shall be effective service of process for any suit, action or proceeding relating to any dispute arising out of this Agreement or the transactions contemplated by this Agreement.

(c) EACH PARTY HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR OTHER PROCEEDING ARISING OUT OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

9.7 Entire Agreement

This Agreement, together with the Non-Disclosure Agreement, and any documents delivered hereunder, constitutes the entire agreement between the Parties and supersedes all prior agreements and understandings, both written and oral, among the Parties, with respect to the subject matter thereof.

9.8 Third Party Beneficiaries

Except as provided in Section 5.6, this Agreement shall not confer any rights or remedies upon any Person other than the Parties and their respective successors and permitted assigns.

9.9 Amendment

This Agreement may, at any time and from time to time but not later than the Closing, be amended by written agreement of the Parties hereto without, subject to applicable Laws, further notice to or authorization on the part of the Pozen Stockholders.

9.10 Waiver and Modifications

Any Party may (a) waive, in whole or in part, any inaccuracy of, or consent to the modification of, any representation or warranty made to it hereunder or in any document to be delivered pursuant hereto, (b) extend the time for the performance of any of the obligations or acts of the other Parties, (c) waive or consent to the modification of any of the covenants herein contained for its benefit or waive or consent to the modification of any of the obligations of the other Parties hereto or (d) waive the fulfillment of any condition to its own obligations contained herein. No waiver or consent to the modifications of any of the provisions of this Agreement will be effective or binding unless made in writing and signed by the Party or Parties purporting to give the same and, unless otherwise provided, will be limited to the specific breach or condition waived. The rights and remedies of the Parties hereunder are cumulative and are in addition to, and not in substitution for, any other rights and remedies available at Law or in equity or otherwise. No single or partial exercise by a Party of any right or remedy precludes or otherwise affects any further exercise of such right or remedy or the exercise of any other right or remedy to which that Party may be entitled. No waiver or partial waiver of any nature, in any one or more instances, will be deemed or construed a continued waiver of any condition or breach of any other term, representation or warranty in this Agreement.

9.11 Severability

Upon such determination that any provision is illegal, invalid or unenforceable, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the Arrangement and Merger be consummated as originally contemplated to the fullest extent possible.

9.12 Further Assurances

Subject to the provisions of this Agreement, the Parties will, from time to time, do all acts and things and execute and deliver all such further documents and instruments, as the other Parties may, either before or after the Closing, reasonably require to effectively carry out or perfect the full intent and meaning of this Agreement.

9.13 Injunctive Relief

(a) Except as otherwise expressly provided herein, any and all remedies herein expressly conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by Law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached for which money damages would not be an adequate remedy at Law or otherwise. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement and this right shall include the right of the parties to cause the transactions contemplated by this Agreement to be consummated on the terms set forth in this Agreement, in each case without posting a bond or undertaking, this being in addition to any other remedy to which they are entitled at Law or in equity or pursuant to this Agreement. Each of the parties hereto hereby waives any defenses in any action for specific performance, including the defense that a remedy at Law would be adequate.

(b) Notwithstanding the parties’ rights to specific performance or injunctive relief or both pursuant to Section 9.13(a), each party may pursue any other remedy available to it at Law or in equity, including monetary damages; provided that it is understood and agreed that claims for monetary damages following termination of this Agreement shall be limited to those arising from or relating to any intentional or willful breach of this Agreement prior to such termination.

9.14 No Recourse

Without limiting any other provision in this Agreement, this Agreement may be enforced only against, and any claims or causes of action that may be based upon, arise out of or relate to this Agreement, or the negotiation, execution or performance of this Agreement, may be made only against the Parties hereto.

9.15 Counterparts

This Agreement may be executed and delivered in any number of counterparts (including by facsimile or electronic transmission), each of which will be deemed to be an original and all of which taken together will be deemed to constitute one and the same instrument, and each Party may enter into this Agreement by executing a counterpart and delivering it to the other Party (by personal delivery, facsimile, electronic transmission or otherwise).
