Authority, other than registrations or other actions required under federal and state securities Laws as are contemplated by this Agreement.

(d) Tribute Reporting Issuer. Tribute has been a “reporting issuer” (as such term is defined in Canadian Securities Laws) in a jurisdiction of Canada for the four months preceding the date of this Agreement and will be a reporting issuer not in default immediately preceding the Investment Closing and until the Plan of Arrangement is effected.

(e) SEC Filings. Tribute has timely filed or received the appropriate extension of time within which to file with the Commission all forms, reports, schedules, statements and other documents required to be filed by it since January 1, 2014 under the Exchange Act or the Securities Act (such documents, as supplemented and amended since the time of filing, collectively, the “Tribute SEC Documents”). The Tribute SEC Documents, including any financial statements or schedules included therein, at the time filed (and, in the case of registration statements and proxy statements, on the dates of effectiveness and the dates of mailing, respectively) (i) did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading and (ii) complied in all material respects with the applicable requirements of the Exchange Act and the Securities Act, as the case may be. The financial statements of Tribute included in the Tribute SEC Documents at the time filed complied as to form in all material respects with applicable accounting requirements and with the published rules and regulations of the Commission with respect thereto, were prepared in accordance with GAAP during the periods involved (except as may be indicated in the notes thereto, auditor’s report thereon or, in the case of unaudited statements, as permitted by Form 10-Q of the Commission), and fairly present in all material respects (subject in the case of unaudited statements to normal audit adjustments and subject to restatements filed with the Commission prior to the date of this Agreement) the consolidated financial position of Tribute and its consolidated Subsidiaries as at the dates thereof and the consolidated results of their operations and cash flows for the periods then ended. No Subsidiary of Tribute is subject to the periodic reporting requirements of the Exchange Act other than as part of Tribute’s consolidated group or required to file any form, report or other document with the Commission, NASDAQ, the TSX, any other stock exchange or comparable Governmental Authority.

(f) Private Placement. Assuming that the representations of each Co-Investor set forth in Section 4.1(c) are true and correct and assuming that the representation of Pozen set forth in Section 3.2(d) is true and correct, the initial allotment and issuance of the Shares in conformity with the terms of this Agreement are exempt from both (i) the registration requirements of Section 5 of the Securities Act and (ii) the prospectus requirements of the Canadian Securities Laws, and neither Tribute nor any authorized agent acting on its behalf will take any action hereafter that would cause the loss of such exemptions. Neither Tribute nor, to Tribute’s knowledge, any person acting on behalf of Tribute has offered or sold any of the Shares by any form of “general solicitation” or “general advertising”, as such terms are used in Rule 502(c) of Regulation D under the Securities Act.

(g) Registration Statement and Investor Registration Statement. None of the information supplied or to be supplied by Tribute for inclusion or incorporation by reference in

the Registration Statement or the Investor Registration Statement to be filed with the Commission by the Company under the Securities Act at the time the Registration Statement or Investor Registration Statement becomes effective will contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading (it being understood that no representation or warranty is made by Tribute with respect to statements made or incorporated by reference therein based on written information supplied by Purchaser expressly for inclusion or incorporation by reference in the Registration Statement or the Investors expressly for inclusion or incorporation by reference in the Investor Registration Statement). Each of the Registration Statement, except for such portions thereof that relate only to Purchaser and its Subsidiaries, and the Investor Registration Statement, except for such portions thereof that relate only to Investors, will comply as to form in all material respects with the provisions of the Securities Act.

ARTICLE VIII

MISCELLANEOUS

8.1 Survival. Notwithstanding any investigation made by any party to this Agreement, all covenants, agreements, representations and warranties made by the Company, Tribute, Pozen or the Co-Investors herein shall survive the execution of this Agreement, the delivery to the Co-Investors of the Shares and the payment therefor.

8.2 Expenses. Except as otherwise provided in this Agreement, whether or not the transactions contemplated by this Agreement are consummated, all costs and expenses incurred in connection with the negotiation and execution of this Agreement and the transactions contemplated hereby shall be paid by the party incurring or required to incur such expenses, including the Registration Expenses and Investor Registration Expenses (which shall be from the account of the Company).

8.3 Counterparts; Effectiveness. This Agreement may be executed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures

Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature.

Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts. Each of the parties hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (a) any claim that it is not personally subject to the jurisdiction of the above named courts, (b) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) to the fullest extent permitted by applicable Law, any claim that (i) the suit, action or proceeding in such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts. To the fullest extent permitted by applicable Law, each of the parties hereto hereby consents to the service of process in accordance with Section 8.7; provided, however, that nothing herein shall affect the right of any party to serve legal process in any other manner permitted by Law.

If to an Investor, at its address set forth under its name on Schedule I hereto,

or to such other address as any party shall specify by written notice so given, and such notice shall be deemed to have been delivered as of the date so telecommunicated or personally delivered. Any party to this Agreement may notify any other party of any changes to the address or any of the other details specified in this Section 8.7; provided, however, that such notification shall only be effective on the date specified in such notice or five (5) Business Days after the notice is given, whichever is later. Rejection or other refusal to accept or the inability to deliver because of changed address of which no notice was given shall be deemed to be receipt of the notice as of the date of such rejection, refusal or inability to deliver.

8.8 Assignment; Binding Effect. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned or delegated by any of the parties hereto without the prior written consent of the other parties; provided, however, that (i) any Co-Investor may assign any of its rights hereunder to any of its Affiliates without the prior written consent of the Company, Tribute or Pozen, but no such assignment shall relieve such Co-Investor of any of its obligations hereunder, (ii) at any time prior to the filing of the Investor Registration Statement or the Registration Statement, as applicable, any Co-Investor may reallocate, in whole or in part, the number of Shares allocated to such Co-Investor hereunder and assign its rights and obligations hereunder with respect to such reallocated Shares, to any other Co-Investor (and Schedule I will be updated accordingly), and (iii) Purchaser may assign any of its rights hereunder in connection with a merger or amalgamation of Purchaser, or the sale of all or substantially all of the assets of Purchaser and its Subsidiaries. In addition to the foregoing, the Company hereby acknowledges and agrees that, following the Arrangement Effective Time and pursuant to the Plan of Arrangement, the Company shall assume the obligations of Tribute with respect to the Purchaser Shares and the Investor Shares. Subject to the first sentence of this Section 8.8, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns. Any purported assignment not permitted under this Section 8.8 shall be null and void. In addition, if Purchaser were to sell in a private transaction any of its Shares to (i) another Co-Investor or (ii) one or more persons identified on Schedule II hereto, then such purchaser shall have the rights set forth in Annex A hereto with respect to such purchased Shares.

8.9 Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only so broad as is enforceable.

8.10 Independent Legal and Investment Advice. Each party acknowledges that Weil, Gotshal & Xxxxxx LLP, XxXxxxxxxx O’Xxxxxx Xxxxx LLP and Xxxxxxxxx & Co., LLC are advisors to the Purchaser and not any other party to this Agreement. In addition, each party to this Agreement acknowledges having had the opportunity to obtain independent legal advice and independent investment advice in connection with the execution of this Agreement and the transactions contemplated hereby, prior to the execution of this Agreement, and further, each party to this Agreement represents to the other parties that it has either sought independent legal advice and independent investment advice or has waived its right to seek such advice.

8.11 Entire Agreement. This Agreement together with the annexes, schedules and exhibits hereto and each of the Confidentiality Agreements constitute the entire agreement, and supersede all other prior agreements and understandings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof and thereof, and this Agreement is not intended to grant standing to any person other than the parties hereto. For greater certainty the Original Agreement is terminated hereby.

8.12 Amendments; Waivers. At any time prior to the Effective Time, any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by the Company, Tribute, Pozen, Purchaser and each of the Investors; provided, however, that any amendment or waiver of any of the provisions of Annex A shall require only the signature of the Company and the affected Investor, and any amendment or waiver of Annex B shall only require the signature of the Company and Purchaser. Notwithstanding the foregoing, no failure or delay by any party hereto in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

8.13 Headings. Headings of the Articles and Sections of this Agreement are for convenience of the parties only and shall be given no substantive or interpretive effect whatsoever. The table of contents to this Agreement is for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

8.14 No Third-Party Beneficiaries. Each of the Co-Investors, Pozen, Tribute and the Company agrees that (a) their respective representations, warranties, covenants and agreements set forth herein are solely for the benefit of the other party hereto, in accordance with and subject to the terms of this Agreement, and (b) this Agreement is not intended to, and does not, confer upon any person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein, with the exception of the rights and remedies of the Indemnified Parties pursuant to Annex B.

8.15 Obligations of the Co-Investors and the Company. The obligations of the Co-Investors are several and not joint and the breach by any Co-Investor of its obligations hereunder shall not result in any liability being incurred by any one or more of the other Co-Investors as a result of such breach. Each of the Company, Tribute and Pozen acknowledges and agrees that should one or more Co-Investors not be ready, willing and able to subscribe for its respective Shares hereunder, any of the other Co-Investors may subscribe for such Shares in lieu of the non-performing Co-Investor.

(f) “Selling Expenses” shall mean all selling commissions and transfer taxes applicable to the sale, transfer, issuance or allotment of Registrable Securities and all fees and disbursements of counsel for Investors.

1.2 Registration Requirements. The Company shall use its commercially reasonable efforts to effect the registration of the resale of the Registrable Securities (including, without limitation, the execution of an undertaking to file post-effective amendments, appropriate qualification under applicable Blue Sky or other state securities laws and appropriate compliance with applicable regulations issued under the Securities Act) as would permit or facilitate the resale of all the Registrable Securities in the manner (including manner of sale) and in all states reasonably requested by the Investors, provided that in no event shall the Company be required to register the resale of the Registrable Securities in an underwritten offering. Such commercially reasonable efforts by the Company shall include, without limitation, the following:

(a) The Company shall use commercially reasonable efforts to, as expeditiously as possible:

(i) prepare and promptly following the filing of Registration Statement on Form S-4 by the Company (in no event later than January 15, 2016), file a registration statement with the Commission pursuant to Rule 415 under the Securities Act covering resales by the Investors as selling stockholders (not underwriters) of the Registrable Securities (the “Investor Registration Statement”). The Company shall use its commercially reasonable efforts to cause such Investor Registration Statement and other filings to be declared effective as soon as possible following its filing.

(ii) respond to all Commission comments, inquiries and requests, and shall request acceleration of effectiveness of the Investor Registration Statement at the earliest possible date. The Company shall provide the Investors reasonable opportunity to review the portions of any such Investor Registration Statement or amendment or supplement thereto containing disclosure regarding the Investors prior to filing.

(iii) prepare and file with the Commission such amendments and supplements to such Investor Registration Statement and the Investor Prospectus used in connection with such Investor Registration Statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Investor Registration Statement and notify the Investors of the filing and effectiveness of such Investor Registration Statement and any amendments or supplements.

A-2

(iv) furnish or otherwise make available to each Investor copies of a current prospectus included in the Investor Registration Statement conforming with the requirements of the Securities Act, copies of the Investor Registration Statement, any amendment or supplement thereto and any documents incorporated by reference therein and such other documents as such Investor may reasonably require in order to facilitate the disposition of Registrable Securities owned by such Investor.

(v) register and qualify the securities covered by the Investor Registration Statement under the securities or “Blue Sky” Laws of all domestic jurisdictions, to the extent required; provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions.

(vi) notify each Co-Investor of the happening of any event (but not the substance or details of any such events) as a result of which the Investor Prospectus (including any supplements thereto or thereof) included in such Investor Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and use its commercially reasonable efforts to promptly update and/or correct such prospectus.

(vii) notify each Investor of the issuance by the Commission or any state securities commission or agency of any stop order suspending the effectiveness of the Investor Registration Statement or the threat or initiation of any proceedings for that purpose. The Company shall use its commercially reasonable efforts to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible time.

(viii) if required by the NASDAQ or the principal securities exchange and/or market on which the Company’s common shares are then listed, qualify the Registrable Securities covered by such Investor Registration Statement for listing on the NASDAQ or the principal securities exchange and/or market on which the Company’s common shares are then listed, including the preparation and filing of any required filings with such principal market or exchange.

(b) The Company may suspend the use of any Investor Prospectus used in connection with the Investor Registration Statement only in the event, and for such period of time as, (i) such a suspension is required by the rules and regulations of the Commission or any self-regulatory organization, or (ii) it is determined in good faith by the Board of the Company that because of valid business reasons (not including the avoidance of the Company’s obligations hereunder), it is in the best interests of the Company to suspend such use, and prior to suspending such use in accordance with this clause (b) the Company provides the Investors with written notice of such suspension, which notice need not specify the nature of the event giving rise to such suspension. The Company will use commercially reasonable efforts to cause such suspension to terminate at the

A-3

earliest possible date. Notwithstanding the foregoing, the use of any Investor Prospectus may be suspended by reason of clause (ii) of this subsection (b) for a period of time not to exceed (A) sixty consecutive days for any one such suspension or (B) an aggregate of ninety days during the Investor Registration Period.

(c) The Company shall prepare and file with the Commission such amendments (including post-effective amendments) and supplements to the Investor Registration Statement and the Investor Prospectus used in connection with the Investor Registration Statement, which prospectus is to be filed pursuant to Rule 424 promulgated under the Securities Act, as may be necessary to keep the Investor Registration Statement effective at all times during the Investor Registration Period (as defined below), and, during such period, comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities of the Company covered by the Investor Registration Statement. In the case of amendments and supplements to the Investor Registration Statement which are required to be filed pursuant to this Agreement (including pursuant to this Section 1.2(c)) by reason of the Company filing a report on Form 10-K, Form 10-Q or Form 8-K or any analogous report under the Exchange Act, the Company shall have incorporated such report by reference into the Investor Registration Statement, if applicable, or shall file such amendments or supplements with the Commission on the same day on which the Exchange Act report is filed which created the requirement for the Company to amend or supplement the Investor Registration Statement.

(d) Each Investor agrees by its acquisition of the Registrable Securities that, upon receipt of a notice from the Company of the occurrence of any event of the kind described in Sections 1.2(a)(vi) or 1.2(a)(vii), and upon notice of any suspension under Section 1.2(b), such Investor will forthwith discontinue disposition of such Registrable Securities under the Investor Registration Statement until such Investor’s receipt of the copies of the supplemented prospectus and/or amendment to the Investor Registration Statement contemplated by this Section 1.2, or until it is advised in writing by the Company that the use of the applicable prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such prospectus or the Investor Registration Statement. The Company may provide appropriate stop orders to enforce the provisions of this paragraph.

(e) If requested by an Investor, the Company shall (i) as soon as practicable incorporate in a prospectus supplement or post-effective amendment such information as an Investor reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including, without limitation, information with respect to the number of Registrable Securities being offered or sold, the Subscription Price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering, (ii) as soon as practicable make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment, and (iii) as soon as practicable, supplement or make amendments to the Investor Registration Statement if reasonably requested by an Investor holding any Registrable Securities.

A-4

1.3 Expenses of Investor Registration. All Investor Registration Expenses in connection with any registration, qualification or compliance with registration pursuant to this Agreement shall be borne by the Company, and all Selling Expenses of an Investor shall be borne by such Investor.

1.4 Investor Registration Period. In the case of the Investor Registration, the Company shall keep such registration effective from the date on which the Investor Registration Statement initially became effective until the earlier of: (i) the date on which all the Investors have completed the sales or distribution described in the Investor Registration Statement relating to the Registrable Securities registered for resale thereunder; (ii) until such Registrable Securities may be sold by the Investors without restriction pursuant to Rule 144 (or any successor thereto); or (iii) one year from the effective date of the Investor Registration Statement (the “Investor Registration Period”). Thereafter, the Company shall be entitled to withdraw such Investor Registration Statement and the Investors shall have no further right to offer or sell any of the Registrable Securities registered for resale thereon pursuant to the Investor Registration Statement (or any prospectus relating thereto).

1.5 Indemnification.

(a) Indemnification by the Company. The Company agrees to indemnify and hold harmless, to the fullest extent permitted by Law, (i) each Investor and its officers, directors, stockholders, employees, advisors, agents and Affiliates, (ii) each Investor’s Affiliates’ officers, directors, stockholders, employees, advisors, agents, and (iii) each Person who controls (within the meaning of the Securities Act, the Exchange Act) such Persons, against any and all claims, losses, damages, penalties, judgments, suits, costs, liabilities and expenses (or actions in respect thereof) (collectively, the “Losses”) arising out of or based on (A) any untrue statement (or alleged untrue statement) of a material fact contained in the Investor Registration Statement (including any Investor Prospectus) or any other document incorporated by reference therein, (B) any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not false or misleading (in the case of any Investor Prospectus, in light of the circumstances under which they were made), or (C) any violation by the Company of the Securities Act, the Exchange Act, the Canadian Securities Laws or any state securities or “Blue Sky” Laws applicable to the Company, and will reimburse each of the Persons listed above, for any reasonable and documented out-of-pocket legal and any other expenses reasonably incurred in connection with investigating and defending any such Losses; provided, that the Company will not be liable in any such case to the extent that any such Losses arise out of or are based on any untrue statement or omission based upon written information furnished to the Company by such Person and stated to be specifically for use in such Investor Registration Statement or Investor Prospectus.

(b) Indemnification by Investors. Each Investor agrees to indemnify and hold harmless, to the fullest extent permitted by Law, (i) the Company and its officers, directors, stockholders, employees, advisors, agents and Affiliates, (ii) each of the Company’s Affiliates’ officers, directors, stockholders, employees, advisors, agents, and (iii) each Person who controls the Company (within the meaning of the Securities Act, the

Exchange Act or the Canadian Securities Laws), against any and all Losses arising out of or based on (A) any untrue statement (or alleged untrue statement) of a material fact made by such Investor contained in the Investor Registration Statement (including any Investor Prospectus) or any other document incorporated by reference therein or (B) any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements by such Investor therein not false or misleading (in the case of any Investor Prospectus, in light of the circumstances under which they were made), and will reimburse the Persons listed above for any reasonable and documented legal or any other expenses reasonably incurred in connection with investigating or defending any such Losses, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in reliance upon and in conformity with written information furnished to the Company by such Investor and stated to be specifically for use in such Investor Registration Statement or Investor Prospectus, provided, however, that the obligations of each Investor hereunder shall be limited to such Investor’s respective Subscription Price.

(c) Conduct of the Indemnification Proceedings. Each Person entitled to indemnification under this Section 1.5 (the “Indemnified Party”) shall give notice to the Person required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld) and the Indemnified Party may participate in such defense at such Indemnified Party’s expense (unless the Indemnified Party shall have reasonably concluded that there may be a conflict of interest between the Indemnifying Party and the Indemnified Party in such action, in which case the fees and expenses of counsel shall be at the expense of the Indemnifying Party); and provided, further, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 1.5 unless the Indemnifying Party is actually and materially prejudiced thereby. It is understood and agreed that the Indemnifying Party shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate legal counsel for all Indemnified Parties; provided, however, that where the failure to be provided separate legal counsel would be reasonably likely to result in a conflict of interest on the part of such legal counsel for all Indemnified Party, separate counsel shall be appointed for the Indemnified Parties to the extent needed to alleviate such potential conflict of interest. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the prior written consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect of such claim or litigation. Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnified Party may reasonably request in writing and as shall be reasonably required in connection with the defense of such claim and litigation resulting therefrom.

(d) Contribution. If the indemnification provided for in this Section 1.5 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any Losses, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party, on the one hand, and the Indemnified Party, on the other, in connection with the statements or omissions (or alleged statements or omissions) which resulted in such Losses, as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue (or alleged untrue) statement of a material fact or the omission (or alleged omission) to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and such parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, however, that the obligations of each Investor shall be limited to an amount equal to the such Investor’s respective Subscription Price; and provided, further, that no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) or gross negligence shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation or gross negligence.

(e) Exclusivity. Subject to the limitations on each Investor’s liability set forth in Section 1.5(b) and Section 1.5(d), the remedies provided for in this Section 1.5 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Party at Law or equity. The remedies shall remain in full force and effect regardless of any investigation made by or on behalf of an Investor or any Indemnified Party and survive the transfer of the Investor Shares by an Investor.

1.6 Survival. The indemnity and contribution agreements contained in Section 1.5 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Indemnified Party or by or on behalf of the Company, and (iii) the consummation of the sale or successive resales of the Registrable Securities.

1.7 Information by Investors. Each Investor shall promptly furnish to the Company such information regarding such Investor and the distribution and/or sale proposed by such Investor as the Company may from time to time reasonably request in writing in connection with any Investor Registration, qualification or compliance referred to in this Agreement, and the Company may exclude from such Investor Registration the Registrable Securities of any Investor who unreasonably fails to furnish such information within a reasonable time after receiving such request. The intended method or methods of disposition and/or sale of such securities as so provided by such purchaser shall be included without alteration in the Investor Registration Statement covering the Registrable Securities and shall not be changed without written consent of such Investor. Each Investor agrees that, other than ordinary course brokerage arrangements, in the event it enters into any arrangement with a broker dealer for the sale of any Registrable Securities through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, such Investor shall promptly deliver to the Company in writing all applicable information required in order for the Company to be able to timely file a

A-7

supplement to the Investor Prospectus pursuant to Rule 424(b), or take any other action, under the Securities Act, to the extent that such supplement or other action is legally required. Such information shall include a description of (i) the name of such Investor and of the participating broker dealer(s), (ii) the number of Registrable Securities involved, (iii) the price at which such Registrable Securities were or are to be sold, and (iv) the commissions paid or to be paid or discounts or concessions allowed or to be allowed to such broker dealer(s), where applicable

(b) Indemnification by Purchaser. Purchaser agrees to indemnify and hold harmless, to the fullest extent permitted by Law, (i) the Company and its officers, directors, stockholders, employees, advisors, agents and Affiliates, (ii) each of the Company’s Affiliates’ officers, directors, stockholders, employees, advisors, agents, and (iii) each Person who controls the Company (within the meaning of the Securities Act, the Exchange Act or the Canadian Securities Laws), against any and all Losses arising out of or based on (A) any untrue statement (or alleged untrue statement) of a material fact made by Purchaser contained in any Registration Statement (including any Prospectus) or any other document incorporated by reference therein or (B) any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements by Purchaser therein not false or misleading (in the case of any Prospectus, in light of the circumstances under which they were made), and will reimburse the Persons listed above for any reasonable and documented legal or any other expenses reasonably incurred in connection with investigating or defending any such Losses, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in reliance upon and in conformity with written information furnished to the Company by Purchaser and stated to be specifically for use in such Registration Statement or Prospectus, provided, however, that the obligations of Purchaser hereunder shall be limited to the Subscription Price.
