Protox Therapeutics Inc., a British Columbia corporation (the “Company”), hereby agrees with Warburg Pincus Private Equity X, L.P., a Delaware limited partnership (together with any successor, assign or transferee, including any transferee of the Units, as permitted herein, Common Shares or Warrants (each, as defined herein), “WPX”), and Warburg Pincus X Partners, L.P., a Delaware limited partnership (together with any successor, assign or transferee, including any transferee of the Units, as permitted herein, Common Shares or Warrants, “WP Partners,” and together with WPX, each a “Purchaser” and collectively the “Purchasers”), as follows:

SECTION 1. AUTHORIZATION OF SECURITIES

The Company has duly authorized the issuance and sale of 87,500,000 units of the Company (“Units”), each of which consists of (i) one common share of the Company, without par value (the “Common Shares”) and (ii) a warrant (the “Warrants”) exercisable for sixty one-hundredths (.6) of a Common Share, which Warrants will have the terms set forth in (i) a Warrant Agreement to be entered into on the First Closing Date (the “Initial Investment Warrant Agreement”), the form of which is attached hereto as Exhibit A and (ii) with respect to Units issued on each Subsequent Closing Date, a Warrant Agreement to be entered into on such Subsequent Closing Date (each a “Subsequent Investment Warrant Agreement,” and together with the Initial Investment Warrant Agreement, the “Warrant Agreements”), the form of which is attached hereto as Exhibit B. References to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement, including the Transaction Documents. References to $ or dollar amounts herein refer to Canadian dollars. Capitalized terms used herein and not otherwise defined shall have the meanings ascribed to such terms in Section 8.1 of this Agreement.

SECTION 2. PURCHASE AND SALE OF SECURITIES

2.1 Issuance and Sale of Initial Investment Units.

(a) Subject to the terms and conditions set forth in this Agreement, and in reliance upon the Company’s and each Purchaser’s representations set forth herein, on the First Closing Date, the Company shall issue and sell to the Purchasers free and clear of all Liens, and the Purchasers shall purchase from the Company, the number of Units set forth opposite each Purchaser’s name on Schedule 2.1 (collectively, such Units are referred to as the “Initial Investment Units”) for the aggregate cash purchase price set forth opposite each Purchaser’s name on Schedule 2.1 for such Initial Investment Units (such aggregate purchase price, the “Initial Investment Purchase Price”). The purchase and sale of the Initial Investment Units shall be effected on the First Closing Date by the Company executing and delivering to the Purchasers free and clear of all Liens, (i) duly executed share certificates, duly registered in each Purchaser’s name, evidencing the Common Shares underlying the Initial Investment Units being purchased by each Purchaser and (ii) a duly executed Initial Investment Warrant Agreement,

dated as of the First Closing Date, with respect to the Warrants underlying the Initial Investment Units, against delivery by such Purchaser to the Company of the portion of the Initial Investment Purchase Price payable by such Purchaser, by wire transfer of immediately available funds to the Company’s bank account previously provided to the Purchasers by the Company (the “Company Bank Account”).

(b) The closing of the transactions contemplated by Section 2.1(a) of this Agreement (the “First Closing”) shall take place at 10:00 a.m., New York City time, on the date five (5) Business Days after the conditions to the First Closing set forth in Sections 6.1 and 6.2 hereof are satisfied or waived by the applicable party in the manner permitted by Sections 6.1 and 6.2 (other than those conditions that by their nature are to be satisfied by actions taken at the First Closing, which must be satisfied or waived at the First Closing), or on such other date as may be mutually agreed in writing by the Company and the Purchasers (the “First Closing Date”).

(c) Each of the First Closing and each Subsequent Closing shall take place at the offices of Xxxxxxx Xxxx & Xxxxxxxxx LLP, 787 Seventh Avenue, New York, New York, or such other location as the Purchasers and the Company shall mutually select.

2.2 Issuance and Sale of Additional Investment Units.

(a) Subject to the terms and conditions set forth in this Agreement, including without limitation satisfaction of the Regulatory Condition before the Regulatory Condition Outside Date and the other conditions set forth in Section 7.1, and in reliance upon the Company’s and each Purchaser’s representations set forth herein, on the Subsequent Closing Date (as defined below), the Company shall issue and sell to the Purchasers free and clear of all Liens, and the Purchasers shall purchase from the Company, the number of Units set forth opposite each Purchaser’s name on Schedule 2.2 (collectively, such Units are referred to as the “Subsequent Investment Units”) for the aggregate cash purchase price set forth opposite each Purchaser’s name on Schedule 2.2 for such Subsequent Investment Units (such aggregate purchase price, the “Subsequent Investment Purchase Price”). In the event that any of the conditions set forth in Section 7.1, including the Regulatory Condition, shall not have been satisfied before the Regulatory Condition Outside Date, the obligations of the parties to consummate the purchase, issuance and sale pursuant to this Section 2.2(a) shall terminate automatically and be of no further force and effect.

(b) In the event that any of the conditions set forth in Section 7.1, including the Regulatory Condition, have not been satisfied before the Regulatory Condition Outside Date, each Purchaser shall have the right, but not the obligation, in its sole discretion, to purchase from the Company, in one or more Subsequent Closings, all or a portion of the Subsequent Investment Units set forth opposite such Purchaser’s name on Schedule 2.2 for such portion of the Subsequent Investment Purchase Price corresponding to the portion of Subsequent Investment Units to be purchased, provided, however, that the Subsequent Investment Units to be purchased by the Purchasers in the aggregate at any Subsequent Closing shall be no fewer than 20,833,333 Units; provided further, however, that notwithstanding the foregoing, the Subsequent Investment Units to be purchased by the Purchasers in the aggregate at any Subsequent Closing may be less than 20,833,333 Units if (a) at least 41,666,666 Subsequent Investment Units were previously

purchased by the Purchasers in the aggregate and (b) the Purchasers in the aggregate are purchasing all of the remaining Subsequent Investment Units issuable hereunder. A Purchaser’s election pursuant to this Section 2.2(b) shall be effected by providing written notice to the Company of its election thereof during the Subsequent Investment Election Period (such notice, the “Subsequent Investment Notice”), which notice shall specify the aggregate number of Subsequent Investment Units such Purchaser intends to purchase in connection with such Subsequent Closing and the proposed Subsequent Closing Date for the purchase, sale and issuance contemplated by such Subsequent Investment Notice. The Subsequent Closing Date specified in the Subsequent Investment Notice must be at least ten (10) Business Days and not more than fifteen (15) Business Days from the date of receipt by the Company of the Subsequent Investment Notice, provided, however, that the Subsequent Closing Date must be on or before the Subsequent Investment Outside Date. Notwithstanding anything to the contrary set forth herein, each Purchaser may revoke any Subsequent Investment Notice provided by it at any time prior to the Subsequent Closing in respect thereof by written notice to the Company of such revocation. In the event that a Subsequent Investment Notice is revoked by a Purchaser, such Purchaser shall retain the right to purchase the Subsequent Investment Units contemplated to be purchased in the Subsequent Investment Notice so revoked, subject to the terms and conditions of this Agreement, by again complying with the procedures set forth herein with respect to the purchase of such Subsequent Investment Units.

(c) The purchase and sale of Subsequent Investment Units shall be effected on the applicable Subsequent Closing Date by the Company executing and delivering to the Purchasers free and clear of all Liens (i) duly executed share certificates, duly registered in each Purchaser’s name, evidencing the Common Shares underlying the Subsequent Investment Units being purchased by each Purchaser on such Subsequent Closing Date and (ii) a duly executed Subsequent Investment Warrant Agreement, dated as of such Subsequent Closing Date, with respect to the Warrants underlying the Subsequent Investment Units being issued on such Subsequent Closing Date, against delivery by such Purchaser to the Company of the portion of Subsequent Investment Purchase Price payable by such Purchaser in respect thereof, by wire transfer of immediately available funds to the Company Bank Account.

(d) The closing of the transactions contemplated by Section 2.2(a) of this Agreement shall take place at 10:00 a.m., New York City time, on a day to be mutually agreed upon by the Purchasers and the Company, which day shall be within fifteen (15) Business Days following the satisfaction of the Regulatory Condition, subject to the conditions to closing set forth in Sections 7.1 and 7.2 hereof being satisfied or waived by the applicable party in the manner permitted by Sections 7.1 and 7.2 (other than those conditions that by their nature are to be satisfied by actions taken at such closing, which must be satisfied or waived at such closing), or on such other date as may be mutually agreed in writing by the Company and the Purchasers.

(e) The closing or, if applicable, closings, of the transactions contemplated by Section 2.2(b) of this Agreement shall take place at 10:00 a.m., New York City time, on the proposed Subsequent Closing Date set forth in the Subsequent Investment Notice, subject to the conditions to closing set forth in Sections 7.1 and 7.2 hereof being satisfied or waived by the applicable party in the manner permitted by Sections 7.1 and 7.2 (other than those conditions that by their nature are to be satisfied by actions taken at such closing, which must be satisfied or waived at such closing), or on such other date as may be mutually agreed in writing by the

Company and the Purchasers. The closing of the transactions contemplated by Section 2.2(a) of this Agreement and the closing or closings of the transactions contemplated by Section 2.2(b) of this Agreement shall each be a “Subsequent Closing”, and the date on which each such Subsequent Closing shall occur shall each be a “Subsequent Closing Date”.

2.3 Adjustments.

Upon the occurrence of any Adjustment Event (as defined below), the Exercise Price (as defined in the Subsequent Investment Warrant Agreement) and number of Common Shares issuable upon exercise of the applicable Subsequent Investment Warrant Agreement shall be determined (based on all adjustments thereto set forth in the Subsequent Investment Warrant Agreement) as if such Subsequent Investment Warrant Agreement had been issued to the applicable Purchaser at the First Closing. For the avoidance of doubt, the preceding sentence shall not limit any adjustment to the Exercise Price or the number of Common Shares issuable upon exercise of the Subsequent Investment Warrant Agreement for events occurring after the applicable Subsequent Closing.

(e) The Company has implemented and maintains disclosure controls and procedures that ensure that information required to be disclosed by the Company in the reports that it files or submits under Applicable Securities Law is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

(a) Subject to the provisions set forth below, without the prior consent of the Company, each Purchaser will not:

(i) acquire or agree, offer or propose to acquire, other than as contemplated or permitted in the Transaction Documents, directly or indirectly, alone or in concert with any other Person, by purchase or otherwise, any (A) ownership of any of the material assets or businesses of the Company, or any rights or options to acquire such ownership (including from any third party), or (B) Beneficial Ownership of any securities of the Company, or any rights or options to acquire such ownership (including from any third party); provided, however, that the foregoing shall not apply to (x) any Units, Common Shares or Warrants purchased pursuant to the terms of this Agreement or acquired on the exercise thereof or in exchange therefor, or (y) any Units, Common Shares or Warrants purchased pursuant to Permitted Transfers, including as between the Purchasers, or pursuant to the exercise of rights set forth in Section 5.4, or (z) any Common Shares purchased in Market Transfers so long as the aggregate amount of securities purchased in Market Transfers by such Purchaser represents not more than 5% of the Company’s outstanding Common Shares on a Fully Diluted Basis after giving effect to the applicable purchase;

(ii) solicit proxies (as such terms are defined under the Applicable Securities Laws), whether or not such solicitation is exempt under the Applicable Securities Laws, with respect to any matter from holders of any shares of the Company or any securities convertible into or exchangeable for or exercisable (whether currently or upon the occurrence of any contingency) for the purchase of such shares;

(iii) initiate, or intentionally induce any other Person, entity or group (as defined in the Applicable Securities Laws) to initiate, any shareholder proposal or tender

offer for any securities of the Company, any Change of Control of the Company or the convening of a shareholders’ meeting of the Company; or

(iv) enter into any arrangements or understandings with any other Person with respect to any matter described in the foregoing subparagraphs (i) through (iii).

(b) Subject to the provisions set forth below, without the prior consent of the Company, no Purchaser nor any member of the Purchaser Group will short sell any Common Shares.

(c) The provisions of Sections 5.2(a) and (b) shall not apply in respect of any action taken by the Purchaser Designees in their capacity as members of the Board or any proposal by a Purchaser to the Board in a manner that such Purchaser believes in good faith does not require public disclosure by the Company. In addition, notwithstanding the provisions set forth in this Section 5.2, each Purchaser shall be entitled to make any disclosures required by Applicable Law.

(d) The provisions of Section 5.2(a) shall terminate on the earliest of (i) the date that is the first anniversary of the date hereof, (ii) the date on which any Purchaser Designee is not, upon nomination, elected to the Board at any annual meeting of the shareholders of the Company (or at any special meeting held to elect directors in lieu of an annual meeting) and is not otherwise appointed to the Board, (iii) the date of a Change of Control, (iv) the date on which the Company waives any Takeover Provisions for any Person (other than the Purchasers), (v) the date of a material breach by the Company of any term or condition set forth herein, where the Company does not cure such breach within ten (10) days after written notice of such breach from one or more of the Purchasers and (vi) the date of a material breach by the Company of any term or condition of the Warrants, where the Company does not cure such breach within ten (10) days after written notice of such breach from one or more of the Purchasers (such earliest date, the “Standstill Termination Date”). The provision contained in Section 5.2(b) shall terminate on the earliest of (i) the Regulatory Condition Outside Date, (ii) the Standstill Termination Date and (iii) the first Subsequent Closing Date. In addition, the provisions of Sections 5.2(a) and (b) shall not apply at any time after (A) the Board resolves to pursue a Buyout Transaction or a transaction that is contemplated by the Board to result in a Change of Control, (B) the Board approves, recommends or accepts a Buyout Transaction or a transaction that would result in a Change of Control proposed by any Person (other than any Purchaser Group member) or (C) there is a Change of Board Recommendation.

(e) Until the earlier of (a) the third anniversary of the date of this Agreement, (b) the date on which no Purchaser Designee (other than the Purchaser Designee Industry Expert) is a member of the Board, or (c) the Standstill Termination Date if such Standstill Termination Date occurs pursuant to Section 5.2(d)(ii), (iii), (iv), (v) or (vi), each Purchaser shall not solicit proxies (as such terms are defined under the Applicable Securities Laws), whether or not such solicitation is exempt under the Applicable Securities Laws, to replace any Person as a member of the Board. For greater clarity, nothing contained herein shall require any Purchaser to vote its Common Shares for or against the election of any member of the Board.

5.3 Buyout Transactions.

So long as a Purchaser is in compliance with Section 5.1, nothing set forth in Section 5.1 or Section 5.2 shall prohibit such Purchaser from (i) Transferring Units, the Common Shares underlying the Units or the Warrants pursuant to the terms of a Buyout Transaction, (ii) voting its Units, the Common Shares underlying the Units or the Warrants with respect to any Buyout Transaction or (iii) endorsing a Buyout Transaction or any other transaction that would constitute a Change of Control proposed by any Person.

5.4 Preemptive Rights.

(a) If the Company at any time or from time to time makes a Qualified Equity Offering, each of the Purchasers shall for so long as the Purchaser Group has beneficial ownership of Common Shares in an amount equal to at least fifty percent (50%) of the Common Shares (excluding for clarity Common Shares underlying the Warrant Agreements) issued to Purchasers on the First Closing Date, be afforded the opportunity to acquire from the Company, for the same price and on the same terms as such securities are proposed to be offered to others, in the aggregate up to the amount of New Shares required to enable it to maintain its Purchaser Percentage Interest determined prior to the Qualified Equity Offering.

(b) (i) In the event the Company intends to make a Qualified Equity Offering that is an underwritten public offering or a private offering of convertible notes or convertible preferred shares made to financial institutions for resale, no later than three (3) Business Days after the initial filing of a registration statement with the SEC or filing of a prospectus under Applicable Securities Laws, as the case may be, with respect to such underwritten public offering or the commencement of marketing with respect to such Qualified Equity Offering, the Company shall give each Purchaser written notice of its intention (including, in the case of a public offering and to the extent possible, a copy of the prospectus included in the registration statement filed in respect of such offering) describing, to the extent then known, the anticipated amount of securities, range of prices, timing and other material terms of such offering. Each Purchaser shall have ten (10) Business Days from the date of receipt of any such notice (except in the case of a bought deal or overnight marketed offering, in which case each Purchaser shall have one (1) Business Day from the date of receipt of any such notice) to notify the Company in writing that it intends to exercise such preemptive purchase rights and as to the amount of New Shares such Purchaser desires to purchase, up to the maximum amount calculated pursuant to Section 5.4(a) (the “Designated Shares”). Such notice shall constitute a nonbinding indication of interest of such Purchaser to purchase the Designated Shares so specified at the range of prices and other terms set forth in the Company’s notice to it. The failure of a Purchaser to respond during such ten (10) Business Day period (or one (1) Business Day in the case of a bought deal or overnight marketed offering) shall, solely with respect to the Purchaser who fails to respond, constitute a waiver of the preemptive rights only in respect of such offering.

(ii) If the Company proposes to make a Qualified Equity Offering that is not an underwritten public offering or a private offering of convertible notes or convertible preferred stock made to financial institutions for resale (a “Private Placement”), the

Company shall give each Purchaser written notice of its intention, describing, to the extent then known, the anticipated amount of securities, price and other material terms upon which the Company proposes to offer the same. Each Purchaser shall have ten (10) Business Days from the date of receipt of the notice required by the immediately preceding sentence to notify the Company in writing that it intends to exercise such preemptive purchase rights and as to the amount of Designated Shares such Purchaser desires to purchase, up to the maximum amount calculated pursuant to Section 5.4(a). Such notice shall constitute the binding agreement of such Purchaser to purchase the amount of Designated Shares so specified (or a proportionately lesser amount if the amount of New Shares to be offered in such Private Placement is subsequently reduced) upon the price and other terms set forth in the Company’s notice to such Purchaser. The failure of a Purchaser to respond during the ten (10) Business Day period referred to in the second preceding sentence shall, solely with respect to the Purchaser who fails to respond, constitute a waiver of the preemptive rights in respect of such offering only.

(c) (i) If a Purchaser exercises its preemptive purchase rights provided in Section 5.4(b)(ii), the closing of the purchase of the New Shares with respect to which such right has been exercised shall be conditioned on the consummation of the Private Placement giving rise to such preemptive purchase rights and shall take place simultaneously with the closing of the Private Placement or on such other date as the Company and such Purchaser shall agree in writing; provided that the actual amount of Designated Shares to be sold to such Purchaser pursuant to its exercise of preemptive rights hereunder shall be reduced if the aggregate amount of New Shares sold in the Private Placement is reduced and, at the option of such Purchaser (to be exercised by delivery of written notice to the Company within five (5) Business Days of receipt of notice of such increase), shall be increased if such aggregate amount of New Shares sold in the Private Placement is increased. In connection with its purchase of Designated Shares, each Purchaser shall execute an instrument in form and substance reasonably satisfactory to the Company containing representations, warranties and agreements of the Purchaser that are customary for such private placement transactions.

(ii) If a Purchaser exercises its preemptive purchase rights provided in Section 5.4(b)(i), the Company shall offer such Purchaser, if such offering is consummated, the Designated Shares (as adjusted to reflect the actual size of such offering when priced) at the same price as the New Shares are offered to the underwriters or initial purchasers and shall provide written notice of such price to the Purchaser as soon as practicable prior to such consummation. Contemporaneously with the execution of any underwriting agreement or purchase agreement entered into between the Company and the underwriters or initial purchasers of such offering, such Purchaser shall enter into an instrument in form and substance reasonably satisfactory to the Company acknowledging such Purchaser’s binding obligation to purchase the Designated Shares to be acquired by it and containing representations, warranties and agreements of such Purchaser that are customary in such transactions. Any offers and sales pursuant to this Section 5.4 in the context of a public offering shall also be conditioned on reasonably acceptable representations and warranties of such Purchaser regarding its status as the type of offeree to whom a private sale can be made concurrently with a public offering in compliance with Applicable Securities Laws.

(d) In the event a Purchaser fails to exercise its preemptive purchase rights provided in this Section 5.4 within the applicable ten (10) Business Day period or, if so exercised, a Purchaser does not consummate such purchase within the applicable period, the Company shall thereafter be entitled during the period of 90 days following the conclusion of the applicable period to sell or enter into an agreement (pursuant to which the sale of New Shares covered thereby shall be consummated, if at all, within 60 days from the date of such agreement) to sell the New Shares not purchased pursuant to this Section 5.4 at the price and on the terms offered to the Purchasers. In the event the Company has not sold the New Shares or entered into an agreement to sell the New Shares within said 90-day period, the Company shall not thereafter offer, issue or sell such New Shares without first offering such securities to the Purchasers in the manner provided in this Section 5.4.

(e) The Company and each Purchaser shall cooperate in good faith to facilitate the exercise of the Purchaser’s preemptive rights hereunder, including securing any required approvals or consents, in a manner that does not jeopardize the timing, marketing, pricing or execution of any offering of the Company’s securities.

5.5 Reasonable Best Efforts; Further Assurances.

Each of the parties hereto agrees to use its reasonable best efforts to take, or cause to be taken, all action, and to do, or cause to be done, all things necessary or desirable under applicable legal requirements, to consummate and make effective the transactions contemplated by this Agreement and the Transaction Documents, including the execution of any documents or instruments required hereby. If at any time after the First Closing Date, any further action is necessary or desirable to carry out the purposes of this Agreement and the Transaction Documents, including with respect to the Subsequent Closings, the parties hereto shall use their reasonable best efforts to take or cause to be taken all such necessary or desirable action and to execute, and deliver and file, or cause to be executed, delivered and filed, all necessary or desirable documentation. Notwithstanding the foregoing, in no event shall any of the parties hereto be required to amend the terms of this Agreement or any of the Transaction Documents in order to comply with the terms of this Section 5.5.

5.6 Indemnity.

(a) The Company agrees to indemnify and hold each Purchaser and each member of the Purchaser Group and each of their respective officers, directors, partners, managers, members, affiliates, employees and agents, and each Person who controls any of the foregoing and the officers, directors, partners, managers, members, affiliates, employees and agents of each such controlling Person (each an “Indemnified Party” and collectively, the “Indemnified Parties”) harmless against any and all losses, claims, liabilities, damages and expenses of any kind or nature whatsoever including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred (and as incurred) in connection with prosecuting, investigating, defending or preparing to defend any action, suit, proceeding (including any investigation, litigation or inquiry), demand or cause of action that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to:

(i) any inaccuracy in or breach of any of the Company’s representations and warranties in this Agreement or the Transaction Documents or in any certificate delivered by the Company pursuant hereto or thereto;

(ii) the Company’s breach of any agreements or covenants made by the Company in this Agreement or the Transaction Documents or in any certificate delivered by the Company pursuant hereto or thereto; and

(iii) claims by third parties relating to or arising out of the transactions contemplated by this Agreement or the Transaction Documents, or any transaction or any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnified Party is or is threatened to be made a party thereto.

(b) An Indemnified Party will give written notice to the Company of any claim with respect to which it seeks indemnification under this Section 5.6 promptly after discovery by such Indemnified Party of any matters giving rise to a claim for indemnification; provided that the failure of any Indemnified Party to so notify the Company of any such action shall not relieve the Company from any liability which it may have to such Indemnified Party unless the Company shall have been materially and adversely prejudiced by the failure of such Indemnified Party to so notify the Company. In case any such action shall be brought against any Indemnified Party and the Indemnified Party has notified the Company of the commencement thereof, the Company shall be entitled to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party, and after notice from the Company to such Indemnified Party of its election so to assume the defense thereof, the Company will not be liable to such Indemnified Party under this Section 5.6 for any legal or other expense subsequently incurred by such Indemnified Party in connection with the defense thereof; provided, however, that (1) if the Company shall elect not to assume the defense of such claim or action or (2) if the Indemnified Party has been advised by counsel (A) that there may be a conflict between the positions of the Company and of the Indemnified Party in defending such claim or action or (B) that there may be legal defenses available to such Indemnified Party different from or in addition to those available to the Company, then separate counsel for the Indemnified Party shall be entitled to participate in and conduct the defense, in the case of (1) and (2)(A), or such different defenses, in the case of (2)(B), and the Company shall be liable for any reasonable legal or other expenses incurred by the Indemnified Party in connection with the defense. The Company agrees that it shall not, without the Indemnified Party’s prior written consent (which shall not be unreasonably withheld or delayed), settle or compromise any claim or consent to entry of any judgment in respect thereof in any threatened or pending action, suit, claim or proceeding in respect of which indemnification has been sought hereunder unless such settlement or compromise includes an unconditional release of such Indemnified Party from all liability arising out of such action, suit, claim or proceeding.

(c) All reasonable expenses incurred by an Indemnified Party in connection with any threatened or pending action, suit, proceeding (including any investigation, litigation or inquiry), demand or cause of action shall be paid by the Company in advance of the final disposition of such action, suit, proceeding (including any investigation, litigation or inquiry), demand or cause of action if so requested by the Indemnified Party, within twenty (20) days after the receipt by the Company of a statement or statements from the Indemnified Party requesting

such advance or advances. The Indemnified Party may submit such statements from time to time. The Indemnified Party’s entitlement to such expenses shall include those incurred by the Indemnified Party in connection with any proceeding by the Indemnified Party seeking an adjudication or award in arbitration pursuant to this Agreement. Such statement or statements shall reasonably evidence the expenses incurred by the Indemnified Party in connection therewith and shall include or be accompanied by a written undertaking by or on behalf of the Indemnified Party to repay such amount, including any amount incurred in connection with any proceeding by the Indemnified Party seeking an adjudication or award in arbitration pursuant to this agreement, if it is ultimately determined that the Indemnified Party is not entitled to be indemnified against such expenses by the Company pursuant to this Section 5.6. Each written undertaking to pay amounts advanced must be an unlimited general obligation but need not be secured, and shall be accepted without reference to financial ability to make repayment.

(d) The obligations of the Company under this Section 5.6 shall survive the consummation of the transactions contemplated by this Agreement or termination of this Agreement indefinitely.

(e) The indemnification rights contained in this Section 5.6 are not limited or deemed waived by an investigation or knowledge by any Indemnified Party prior to or after the date hereof.

5.7 Consents and Approvals; Shareholder Approval.

(a) Subject to Sections 5.7(b) and 5.7(c), from and after the date hereof, the Company shall use its reasonable best efforts to prepare and file all necessary documentation, to effect all necessary applications, notices, petitions, filings and other documents, and to obtain all necessary permits, consents, orders, approvals and authorizations of, or any exemption by, all third parties and Governmental Authorities, and expiration or termination of any applicable waiting periods, necessary or advisable to consummate the transactions contemplated by this Agreement and the other Transaction Documents, and to perform the covenants contemplated by this Agreement and the other Transaction Documents, and to obtain the Regulatory Condition prior to the Regulatory Condition Outside Date. The Purchasers shall reasonably cooperate with the Company in all actions contemplated by the previous sentence.

(b) The Company and each Purchaser shall use reasonable best efforts to obtain or submit, as the case may be, as promptly as practicable, the approvals and authorizations of, filings and registrations with, and notifications to applicable Governmental Authorities, or expiration or termination of any applicable waiting period, under the HSR Act or competition or merger control laws of other jurisdictions (collectively, the “Antitrust Regulations”), for the transactions contemplated by this Agreement, including each Closing and the other Transaction Documents, to the extent such Antitrust Regulations are applicable to such Purchaser.

(c) (i) As promptly as reasonably practicable after the execution and delivery of this Agreement, the Company shall, unless it has obtained Shareholder Approval by written consent and the TSX has provided confirmation in writing that a meeting of shareholders to approve the Shareholder Proposals is not required, in consultation with each Purchaser (i) establish a record date for, duly call, give notice of, convene and hold the Shareholder Meeting at

a date no later than November 24, 2010; and (ii) prepare the notice of Shareholder Meeting and the accompanying management information circular to be sent to Shareholders in connection with the Shareholder Meeting for the purpose of obtaining the Shareholder Approval, as the same may be amended, supplemented or otherwise modified subject to this Agreement (the “Information Circular”), together with any other documents required by the Articles and Applicable Laws in connection with the Shareholder Meeting. The Information Circular shall include, among other things, the recommendation of the Board as described in Section 5.7(d) and shall otherwise be in form and substance satisfactory to the Purchaser and its advisors, acting reasonably. Unless the Company has obtained Shareholder Approval by written consent and the TSX has provided confirmation in writing that a meeting of shareholders to approve the Shareholder Proposals is not required, as promptly as practicable after the completion of the Information Circular, the Company will file the Information Circular and any other documentation required to be filed under Applicable Laws in all jurisdictions where the Information Circular is required to be filed by the Company and mail or cause to be mailed the Information Circular and any other documentation required to be mailed under the Articles or Applicable Laws in connection with the Shareholder Meeting to each Shareholder and each other Person to whom such documents are required to be sent under the Articles and under Applicable Laws. The Purchasers will provide to the Company, for filing with the TSX, all required personal information forms (“PIFs”) in respect of the Purchasers or the Purchaser Designees required as a result of the consummation of the Transaction, as soon as reasonably practicable after the TSX makes a request for such PIFs, provided that, in the event the TSX requests PIFs from any Person other than a Purchaser Designee, the Company shall, if requested by the Purchasers, permit the Purchasers to negotiate directly with the TSX to limit the required PIFs to the those of the Purchaser Designees, and shall reasonably assist the Purchasers in such negotiation.

(ii) The Company hereby covenants and agrees that (A) the Information Circular will, if and when filed, comply as to form in all material respects with the applicable requirements of Applicable Laws and (B) none of the information included or incorporated by reference in the Information Circular will, at the date it is first mailed to the holders of Common Shares or at the time of the Shareholders Meeting or at the time of any amendment or supplement thereof, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading.

(d) Subject to Sections 5.8(b) and 5.8(c), the Company shall take, in accordance with Applicable Law and the Company Organizational Documents, all action necessary to convene the Shareholders Meeting as promptly as practicable to submit for approval by the requisite vote of the shareholders of the Company the Shareholder Proposals. Subject to Sections 5.8(b) and 5.8(c), in connection with each meeting of shareholders at which the Shareholder Proposals are submitted for a vote of the shareholders of the Company, (A) the Board shall recommend that its shareholders vote in favour of the Shareholder Proposals and (B) neither the Board nor any committee thereof shall withdraw or modify, or propose or resolve to withdraw or modify, the recommendation of the Board that the shareholders of Common Shares vote in favour of the Shareholder Proposals.

(e) The Company shall take all commercially reasonable action to solicit from the shareholders proxies in favour of the Shareholder Proposals and take all other action necessary or advisable to secure the vote or consent of the shareholders that is required by Applicable Law to approve the Shareholder Proposals (including the Shareholder Approval), including, if necessary or appropriate, adjourning the Shareholders Meeting to solicit additional proxies; provided, however, that the Company shall have no obligation to retain the services of an investment banker or proxy solicitation firm to solicit proxies. Notwithstanding anything herein to the contrary, unless this Agreement has been terminated pursuant to Section 9, the Company will take all of the actions contemplated by this Section 5.7(e) regardless of whether there has been a Change of Board Recommendation, and will submit the Shareholder Proposals to the shareholders of the Company at such Shareholders Meeting.

(f) Each of the Purchasers and the Company will have the right to review in advance, and to the extent practicable each will consult with the other, in each case subject to Applicable Laws relating to the exchange of information, with respect to all of the information relating to the other party, and any of their respective Subsidiaries, which appears in any filing made with, or written materials submitted to, any third party or any Governmental Authorities in connection with the transactions contemplated by this Agreement and the Transaction Documents. In exercising the foregoing right, each of the parties hereto agrees to act reasonably and as promptly as practicable. Each party hereto agrees to keep the other party apprised of the status of matters relating to completion of the transactions contemplated hereby. The Purchasers and the Company shall promptly furnish to each other, to the extent permitted by Applicable Laws, copies of written communications received by them or their Subsidiaries from, or delivered by any of the foregoing to, any Governmental Authorities in respect of the transactions contemplated by this Agreement or by any Transaction Document.

(g) The Company shall use its reasonable best efforts to prepare and file all necessary documentation, to effect all necessary applications, notices, petitions, filings and other documents and to obtain all necessary permits, consents, orders, approvals and authorizations, as applicable, and take all other action, in order to satisfy the Regulatory Condition by the Regulatory Condition Outside Date.

5.8 No Solicitation.

(a) The Company represents to the Purchasers that, as of the date hereof, it is not, nor are any of its officers, agents or other Representatives, engaged, directly or indirectly, in any negotiations or discussions with any Person or entity other than the Purchasers and their Representatives, with respect to any debt or equity financing (other than a Permitted Offering) or any merger, reorganization, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving the Company (any such transaction being an “Alternate Proposal”). Subject to Sections 5.8(b) and 5.8(c), from the date hereof and until the First Closing Date, the Company shall not, and shall cause its respective officers, agents or other Representatives not to, directly or indirectly:

(I) initiate, solicit or knowingly encourage (including by way of providing information), or facilitate the submission of any inquiries, proposals or offers with respect to, or the making, or completion of, an Alternate Proposal;

(II) participate or engage in any discussions or negotiations with, or furnish or disclose any non-public information relating to the Company to, or otherwise knowingly cooperate with or knowingly assist any Person in connection with, an Alternate Proposal;

(III) approve, endorse or recommend any Alternate Proposal;

(IV) enter into any merger agreement, letter of intent, agreement in principle, acquisition agreement, purchase agreement, option agreement or other similar agreement relating to an Alternate Proposal; or

(V) resolve, propose or agree to do any of the foregoing.

(b) Notwithstanding anything to the contrary contained in Section 5.8(a), if at any time following the date hereof and prior to obtaining the Shareholder Approval, (i) the Company has not breached any provision of Section 5.8(a) and the Company has received a written Alternate Proposal that is not a Financing Proposal (a “Change of Control Proposal”) from a third party that (y) occurs or arises after the date hereof that was neither known to the Board nor reasonably foreseeable as of or prior to the date hereof and (z) the Board believes reasonably and in good faith to be bona fide, (ii) the Board determines in good faith, after consultation with its independent financial advisors and outside legal counsel, that such Change of Control Proposal constitutes or is reasonably likely to lead to a Superior Proposal and (iii) after consultation with its outside legal counsel, the Board determines in good faith that such action is necessary to comply with its fiduciary duties to shareholders under Applicable Law, then the Company may (A) furnish information with respect to the Company to the Person making the Change of Control Proposal and (B) participate in discussions or negotiations with the Person making such Change of Control Proposal regarding such Change of Control Proposal provided, that the Company (x) will not, and will not allow its Representatives to, disclose any non-public information to such Person unless the Company enters into an Acceptable Confidentiality Agreement with such Person prior to disclosing any non-public information to such Person and (y) will first provide to the Purchasers any non-public information that is to be provided or made available to such other Person which was not previously provided or made available to the Purchasers. From and after the date hereof, the Company shall promptly (within 24 hours) notify the Purchasers, orally and in writing, in the event it or any of its Representatives receives (i) an Alternate Proposal or indication by any Person that it is considering making an Alternate Proposal, including any Change of Control Proposal or Financing Proposal, (ii) any request for non-public information relating to the Company other than requests for information in the ordinary course of business unrelated to an Alternate Proposal or (iii) any inquiry or request for discussions or negotiations regarding any Alternate Proposal, and shall include in such notice the material terms and conditions thereof and the identity of the party making such proposal or inquiry and to the extent such Alternate Proposal is a Change of Control Proposal shall keep the Purchasers reasonably apprised as to the status and any material developments, discussions and negotiations concerning the same. Without limiting the foregoing, the Company shall promptly (within 24 hours) notify the Purchasers orally and in writing if it determines to provide non-public information or to engage in discussions or negotiations concerning a Change of Control Proposal pursuant to this Section 5.8(b). Such notice shall include (1) a copy of such Change of Control Proposal, indication of interest, inquiry or request (or, where no such copy

exists or is available, a written description thereof that includes the material terms and conditions thereof), including any material modifications thereto, and (2) the identity of the Person making such Change of Control Proposal, indication of interest, proposal or inquiry. The Company shall keep the Purchasers reasonably informed on a current basis (and in any event no later than within 24 hours of the occurrence of any changes, developments, discussions or negotiations) of the status of any Change of Control Proposal, indication of interest, inquiry or request (including the terms and conditions thereof and of any modification thereto), and any material developments, discussions and negotiations concerning the same.

(c) Neither the Board nor any committee thereof shall directly or indirectly (x) withdraw or modify its recommendation with respect to the Shareholder Proposals in a manner adverse to the Purchasers or publicly propose to do so, or (y)(1) approve or recommend an Alternate Proposal and/or (2) terminate this Agreement to enter into a definitive agreement with respect to a Superior Proposal as provided by Section 9.4; provided, that if at any time prior to obtaining the Shareholder Approval, the Company receives a Change of Control Proposal which the Board determines in good faith, after consultation with its independent financial advisors and outside legal counsel, constitutes a Superior Proposal after giving effect to all of the adjustments to the terms of this Agreement that may be offered by Purchaser (including pursuant to clause (ii) below), then the Board may at any time prior to obtaining the Shareholder Approval (I) withdraw or modify its recommendation with respect to the Shareholder Proposals in a manner adverse to the Purchasers, including by failing to include its recommendation in the Information Circular (a “Change of Board Recommendation”) or (II) take action pursuant to Section 9.4 of this Agreement, in the case of each of clauses (I) and (II) if the Board determines in good faith (after consultation with outside counsel) that such action is necessary to comply with its fiduciary duties to shareholders under Applicable Law; provided, further, that the Board may not effect a Change of Board Recommendation or take action pursuant to Section 9.4: (A) if there was a breach of this Section 5.8 and (B) unless:

(i) the Company shall have provided prior written notice to Purchasers, of its intention to take any action contemplated in this Section 5.8(c) with respect to a Superior Proposal at least five (5) Business Days in advance of taking such action (the “Notice Period”), which notice shall specify the material terms and conditions of any such Superior Proposal (including the identity of the Person making such Superior Proposal), and shall have contemporaneously provided a copy of all of the then current form of the definitive transaction agreements with respect to such Superior Proposal and the documents with respect to any financing of such Superior Proposal;

(ii) prior to effecting such Change of Board Recommendation or taking action pursuant to Section 9.4, the Company shall, and shall cause its financial and legal advisors to, during the Notice Period, negotiate with Purchasers in good faith (to the extent Purchasers desire to negotiate) to make adjustments in the terms and conditions of this Agreement; and

(iii) prior to or concurrently with a termination pursuant to Section 9.4 the Company pays all amounts payable pursuant to, and otherwise complies with, the provisions of Section 9.

In the event of any revisions to the Superior Proposal the Company shall be required to deliver a new written notice to Purchasers and to again comply with the requirements of this Section 5.8(c) with respect to such new written notice. The Company agrees that any violation of this Section 5.8 by the Company or any of its Representatives of any of the foregoing shall be deemed to be a material breach of this Agreement (including this Section 5.8) by the Company.

5.9 Use of Proceeds.

The proceeds received by the Company from the issuance and sale of the Units shall be used by the Company for general corporate purposes.

5.10 Conduct of Business; Prohibition on Certain Actions.

(a) Except with the prior written consent of the Purchasers, from and after the date hereof until the First Closing Date, the Company shall conduct its business in the ordinary course of business, consistent with past practice and shall:

(i) continue to maintain, in all material respects, its properties in accordance with present practices in a condition suitable for their current use;

(ii) use commercially reasonable efforts to keep available generally the services of its present officers and employees, and preserve generally the present relationships with Persons having business dealings with it;

dispositions to, the Company of Units, Common Shares or Warrants, to the extent made by any member of the Purchaser Group who is or will become subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company.

(b) Notwithstanding anything to the contrary contained in the Transaction Documents, if there exists a period (the “Section 16(b) Period”) during which a Purchaser’s purchase of any security pursuant to any Transaction Document would result in liability under Section 16(b) of the Exchange Act, the period during which such security may be purchased if prescribed by such Transaction Document, shall be extended until the date that is the equivalent number of days of such Section 16(b) Period after the later of (i) the expiration date to purchase such Security, if any, or (ii) the date of the end of such Section 16(b) Period (the “Section 16(b) Extension Period”); provided that the Section 16(b) Extension Period shall be no longer than six (6) months and five (5) days.

(b) As promptly as practicable after the Subsequent Closing Date, the Company shall use commercially reasonable efforts (i) to qualify to list its Common Shares on an Approved Market as promptly as practicable and (ii) subject to the qualification for listing set forth in clause (i) hereof, and so long as the Purchasers Beneficially Own any Units, Common Shares or Warrants, to continue the listing or trading of the Common Shares on an Approved Market and to comply in all respects with the Company’s applicable reporting, filing and other obligations under the bylaws or rules of the Approved Market on which the Common Shares are listed for trading. Notwithstanding the foregoing, in no event shall the Company take any action in furtherance of this Section 5.13(b) (y) that is inconsistent with or in conflict with its other obligations pursuant to this Agreement and the Transaction Documents without the prior written consent of the Purchasers or (z) if such action requires the Company to authorize, approve or effect a reverse split of the Common Shares or any other equity security of the Company. The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 5.13.

5.14 Venture Capital Qualifying Investment.

The Company hereby agrees that it shall (i) furnish each Purchaser that is a “venture capital operating company” within the meaning of the Department of Labor “plan asset” regulations (“VCOC”) with such financial and operating data and other information with respect to the business and properties of the Company as the Company prepares and compiles for its directors in the ordinary course and as a Purchaser may from time to time reasonably request, (ii) permit each Purchaser that is a VCOC to discuss the affairs, finances and accounts of the

Company, and to make proposals and furnish advice with respect thereto, with the principal officers of the Company and (iii) invite a representative of each Purchaser that is a VCOC to attend all meetings of the Board in a nonvoting observer capacity if no representative of such Purchaser is a member of the Board and, in this respect, shall give such representative copies of all notices, minutes, consents and other material that it provides to the directors and such representative shall be entitled to participate in discussions of matters brought to the Board that the Company reserves the right to exclude such representative from access to any material or meeting or portion thereof if the Company reasonably believes, upon advice of counsel: that such exclusion is necessary to (A) preserve the attorney-client privilege, (B) protect highly confidential proprietary information or (C) avoid a potential conflict of interest.

5.15 Board Representation.

(a) The Company shall take all permissible corporate action such that on the First Closing Date and subject to Sections 5.15(c), the size of the Board shall be set at nine (9) members and, four (4) individuals designated by the Purchaser Group (each director designated by the Purchaser Group under this Agreement (including Section 5.14 hereof), a “Purchaser Designee,” and collectively, the “Purchaser Designees”) as Board nominees shall be appointed to the Board. On the First Closing Date, the resignation of the Resigning Directors shall become effective pursuant to the terms of the Resignation Letters. Notwithstanding anything contained herein to the contrary, the Purchasers shall be permitted, in their discretion, to defer appointment of one or more of the Purchaser Designees to one or more dates subsequent to the dates specified in this Agreement.

(b) As promptly as practical after the date hereof, the Company shall identify, and no earlier than the First Closing Date and in no event later than the 90th day following the First Closing Date, the Company shall appoint to the Board, a person who qualifies as an independent director pursuant to the listing requirements of the TSX and who is an industry expert with operating experience in the industry of the Company and is reasonably acceptable to the Purchasers and the Company (such person, the “Identified Independent Director”). The earlier to occur of the date on which the Identified Independent Director is appointed to the Board and the 90^th day following the First Closing Date shall be referred to herein as the “Appointment Date”.

(c) Prior to the Appointment Date and after the first Subsequent Closing (provided that one Lions Designee shall have resigned from the Board as contemplated by proviso to Section 5.15(d)(ii)), the Purchaser Group shall only be entitled to designate three (3) Purchaser Designees. After the first Subsequent Closing, the size of the Board shall be set at seven (7) members or other such other number as has been approved by the Board and the Purchasers pursuant to Section 5.10(c)(ii).

(d) Subject to Section 5.15(a) from and after the First Closing Date, the Company shall cause:

(i) the Purchaser Designees to be nominated by the Company to serve on the Board for so long as the Purchaser Group has beneficial ownership of Common Shares in an amount equal to at least fifty percent (50%) of the Common Shares (excluding for clarity Common Shares underlying the Initial Investment Warrant Agreement) issued to Purchasers on the First Closing Date; provided that at least one Purchaser Designee shall at all times be an industry expert with operating experience in the industry of the Company, which may be a consultant or advisor to the Purchasers or their Affiliates (such person, the “Purchaser Designee Industry Expert”);

(ii) two (2) individuals designated by Lions Capital (each director designated by Lions Capital, a “Lions Designee”) to be nominated by the Company to serve on the Board for so long as Lions Capital has beneficial ownership of Common Shares in an amount equal to at least fifty percent (50%) of the Common Shares (excluding for clarity Common Shares underlying the Initial Investment Warrant Agreement) issued to Purchasers on the First Closing Date; provided, however, effective as of the first Subsequent Closing Date, one of the Lions Designees shall resign and from and after such Subsequent Closing Date there shall only be one (1) Lions Designee, each in accordance with the Lions Capital Nomination Agreement;

(iii) the Chief Executive Officer of the Company to be nominated by the Company to serve on the Board;

(iv) two (2) individuals to be nominated by the Company to serve on the Board that are independent of the Purchasers, Lions Capital and the Company, one of which shall be the Identified Independent Director; and

(v) the Board to nominate the Purchaser Designee Industry Expert as the Chairman of the Board, so long as such individual remains independent of the Company under Section 1.4 of National Instrument 52-110-Audit Committees.

In the event either the Purchaser Group or Lions Capital no longer have beneficial ownership of Common Shares in the amounts set forth in clauses (i) and (ii) of this Section 5.15(d), the Company may cause the Purchaser Designees or Lions Designees, as the case may be, to be replaced with nominees independent of the Purchasers, Lions Capital and the Company.

(e) In the event that the Purchasers consent to a change in the size of the Board as contemplated by Section 5.10(c)(ii), unless otherwise waived by the Purchasers, the Purchasers shall have the right to designate that number of Purchaser Designees to be nominated or appointed to the Board to maintain proportional Board representation not less than that set forth in Section 5.15(d). For so long as such membership does not conflict with any Applicable Law or regulation or listing requirement of the TSX or any Approved Market on which the Common Shares are listed for trading (as determined in good faith by the Board), the Purchaser Designees shall be entitled to serve as members of, or observers to, at the Purchaser Designee’s election, each of the committees of the Board, except for any committee formed to consider a

transaction between the Company and a member of the Purchaser Group. The Company acknowledges that the Purchaser Designees intend to hold positions on the Board committees and that following the date hereof the Company will take all actions necessary to arrange for the prompt appointment of the Purchaser Designees to any such committees (subject to the limitations in the immediately preceding sentence).

(f) Solely with respect to those Purchaser Designees that the Purchasers are entitled to designate pursuant to Sections 5.15(a) and/or 5.15(d) (and solely as long as the Purchasers remain entitled to so designate such Purchaser Designees):

(i) The Company shall use its commercially reasonable efforts to have such Purchaser Designees elected as directors of the Company, including, without limitation, by naming such Purchaser Designees in the Company’s management information circular for the election of directors as part of “management’s slate”, soliciting proxies for such Purchaser Designees to the same extent as it does for any of its nominees to the Board, and including the recommendation of the Board in favour of election of the Purchaser Designees; provided, however, that the Company shall have no obligation to retain the services of an investment banker or proxy solicitation firm to solicit proxies. In the event a Purchaser Designee is not elected at a shareholders meeting at which such designee is up for election, the Company shall take such action as is within its control to cause such Purchaser Designee to be appointed to the Board.

(ii) The Purchasers may at any time request a Purchaser Designee to resign, with or without cause. Any vacancy caused by the resignation of Purchaser Designee shall only be filled with another Purchaser Designee. Any vacancy created by any removal of a Purchaser Designee or an election of the Purchasers to defer appointing one or more Purchaser Designees shall also only be filled with another Purchaser Designee. The Company shall not take any action to remove any Purchaser Designee or fill a vacancy reserved for a Purchaser Designee in each case without the consent of the Purchasers, except where the Purchaser Designee is disqualified to act as a director under the Business Corporations Act (British Columbia). Any replacement Purchaser Designees shall be appointed to the Board promptly following notice from the Purchasers and, in any event, within five (5) Business Days.

(iii) Each Purchaser Designee shall be given notice of (in the same manner that notice is given to other members of the Board) all meetings (whether in person, telephonic or otherwise) of the Board, including all committee meetings with respect to committees on which such Purchaser Designee serves. Each Purchaser Designee shall receive a copy of all notices, agendas and other materials distributed to the Board, whether provided to directors in advance or during or after any meeting, regardless of whether such Purchaser Designee will be in attendance at the meeting.

(g) In addition to any other indemnification rights the Purchaser Designees have pursuant to this Agreement and the Organizational Documents, each such Purchaser Designee that serves on the Board shall have the right to enter into, and the Company agrees to enter into, an Indemnification Agreement concurrent with such Purchaser Designee becoming a member of the Board. In addition, concurrent with the execution of an Indemnification

Agreement with each Purchaser Designee, the Company shall enter into the Indemnification Side Letter in the form attached hereto as Exhibit D. The Company shall maintain director and officer insurance covering the Purchaser Designees on the same terms and with the same amount of coverage as is provided to other members of the Board. The Company shall reimburse the reasonable expenses incurred by the Purchaser Designees in connection with attending (whether in person or telephonically) all meetings of the Board or committees thereof or other Company related meetings to the same extent as all other members of the Board are reimbursed for such expenses (or, in case any such expense reimbursement policy shall apply only to non-employee directors, to the same extent as all other non-employee directors). The Purchaser Designees shall be entitled to the same compensation for service on the Board, including, without limitation, cash fees, stock options, deferred share units, restricted stock and other equity and equity-related awards, as is provided to other non-employee directors.

(h) The Company and the Purchasers shall take or cause to be taken all lawful action necessary to ensure at all times as of and following the Closing Date that the Company Organizational Documents are not inconsistent with the provisions of this Agreement and the Transaction Documents or the transactions contemplated hereby or thereby.

(i) Except with the prior written consent of the Purchasers, in no event shall the Company (A) grant Lions Capital or any of its Affiliates the right to nominate any person to the Board, or as an observer to the Board, in any manner which inconsistent with or more expansive than the terms of Section 5.15(d)(ii) or (B) amend or waive any provision of the Lions Capital Nomination Agreement.

5.16 Corporate Opportunity.

In recognition that each Purchaser and its Representatives currently have, and may in the future have or may consider acquiring, investments in Persons with respect to which each Purchaser or its Representatives may serve as an advisor, a director or in some other capacity, and in recognition that each Purchaser and its Representatives may have myriad duties to various investors and partners, and in anticipation that the Company, on the one hand, and each of the Purchasers, on the other hand, may engage in the same or similar activities or lines of business and have an interest in the same areas of corporate opportunities, and in recognition of the benefits to be derived by the Company hereunder and in recognition of the difficulties which may confront any advisor who desires and endeavors fully to satisfy such advisor’s duties in determining the full scope of such duties in any particular situation, the provisions of this Section 5.16 are set forth to regulate, define and guide the conduct of certain affairs of the Company as they may involve such Purchaser and each of the Purchaser’s Designees. Subject to Applicable Law, the Company agrees as follows:

and to pursue, directly or indirectly, any such opportunity for itself, and to direct any such opportunity to another Person, it being understood that such opportunities are presented to the Purchaser and its Representatives by virtue of their unique skill, knowledge, experience, reputation, industry expertise and relationships and not by virtue of the fact that certain Representatives are directors on the Board and accordingly, such opportunities are not and will not be corporate opportunities unless specifically determined to be such under the circumstances and in accordance with Applicable Law.

(b) Such Purchaser and its Representatives shall have no duty (contractual or otherwise) to communicate or present any corporate opportunities to the Company or any of its shareholders or Affiliates or to refrain from any actions specified in this Section 5.16.

Subject to Applicable Laws, the Company acknowledges that this Section 5.16 renounces specified business opportunities as contemplated by Applicable Law.

(d) Nothing in this Section 5.16 shall relieve any Purchaser or any Purchaser’s Representatives from any obligations of confidentiality to the Company, whether arising under Applicable Law, this Agreement or other agreement, or as a result of a fiduciary relationship to the Company.

5.17 Legends.

(a) All certificates representing the Common Shares held by the Purchasers shall bear a legend substantially in the following form:

“UNLESS PERMITTED BY SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE [INSERT DATE THAT IS 4 MONTHS AND A DAY AFTER THE DATE OF ISSUANCE].

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO AN INVESTMENT AGREEMENT (A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY). NO TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY BE MADE EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF SUCH INVESTMENT AGREEMENT.”

(b) Upon request of a Purchaser, upon receipt by the Company of an opinion of counsel reasonably satisfactory to the Company to the effect that such legend is no longer required under Applicable Laws, as the case may be, the Company shall promptly cause the first

paragraph of the legend to be removed from any certificate for any Common Shares to be so transferred and the second paragraph of the legend shall be removed upon the expiration of the transfer restrictions set forth in this Agreement.

5.18 Notice of Marketing Approval.

The Company shall provide each of the Purchasers hereunder with written notice within two (2) Business Days of the date on which the Company first receives written marketing approval in the United States (which for the purposes of clarity shall include “accelerated approval”) from the FDA for a New Drug Application submitted for any of the Company’s products and product candidates, which notice shall specify that such approval has been received and which notice may be accomplished by the Company sending to the Purchasers the applicable press release regarding such approval in accordance with the notice provisions set forth in Section 10.1 hereof.

If requested by the Company, a Representative of a Purchaser must sign the form of nondisclosure agreement in form and substance satisfactory to the Company, acting reasonably; provided, however, the Purchaser Designees shall not be obligated to sign such nondisclosure agreement and, in all cases, such nondisclosure agreement shall be limited to the matters set forth in this Section 5.19.

5.20 Public Announcements.

Purchasers and the Company will consult with each other before issuing any press release or otherwise making any public statements about this Agreement or any of the transactions contemplated by this Agreement.

Section 3. Exercise of Warrant; Term. (A) To the extent permitted by applicable laws and regulations, the right to purchase the Shares represented by this Warrant is exercisable, in whole or in part by the Warrantholder, at any time or from time to time after the date hereof, but in no event later than 11:59 p.m., New York City time, on the fifth anniversary of the date hereof (such time, the “Expiration Time”) and subject to the Acceleration Option, by

(ii) payment of the Exercise Price for the Shares thereby purchased at the election of the Warrantholder in one of the following manners:

(a) by tendering in cash, by certified or cashier’s check payable to the order of the Company, or by wire transfer of immediately available funds to an account designated by the Company; or

(b) by having the Company withhold Common Shares issuable upon exercise of the Warrant equal in value to the aggregate Exercise Price as to which this Warrant is so exercised based on the Market Price of the Common Shares on the last full Trading Day prior to the delivery of this Warrant and the Notice of Exercise to the Company.

(iii) This Warrant and the Shares issuable upon exercise hereof have not been registered under the Securities Act or the securities laws of any state of the United States, and this Warrant may not be exercised within the United States or by or on behalf of any U.S. Person unless under a registration pursuant to the Securities Act or an exemption from the registration requirements of the Securities Act and applicable state securities laws. The Company shall not issue or register Shares or the certificates representing such Shares unless the Warrantholder has executed and delivered to the Company a Notice of Exercise included as Schedule “A” hereto.

(iv) If the Warrantholder does not exercise this Warrant in its entirety, the Warrantholder will be entitled to receive from the Company within a reasonable time, and in any event not exceeding three (3) Business Days, a new warrant certificate in

¹	Amount to be 60% of common shares issuable to Warrantholder in the initial investment.

- 4 -

substantially identical form for the purchase of that number of Shares equal to the difference between the number of Shares subject to this Warrant and the number of Shares as to which this Warrant is so exercised.

(B) (i) Subject to the terms and conditions of this Section 3(B), prior to the Warrant being exercised by a Warrantholder pursuant to Section 3(A), the Company may cause the exercise of the Warrant in whole (and not in part) and issue Shares to the Warrantholder at the Exercise Price.

(ii) The option set forth in Section 3(B)(i) (the “Acceleration Option”) may only by exercised after the second anniversary of the date hereof and prior to the Expiration Time. The Acceleration Option may only be exercised if the arithmetic mean of the Market Price for the twenty (20) full Trading Days preceding the delivery of the Provisional Exercise Notice (as defined below) is greater than three times (3X) the Exercise Price.

(iii) In order to exercise the Acceleration Option, the Company shall deliver written notice (the “Provisional Exercise Notice”) to the Warrantholder by first class mail, postage prepaid, notifying the Warrantholder of (a) the Company’s exercise of the Acceleration Option, (b) the number of Shares to be issued to the Warrantholder upon exercise and conversion (which shall be all of the Shares issuable upon exercise of the Warrant at the relevant time), (c) the Exercise Price and (d) the date on which such conversion and the issuance of Shares shall occur, which date shall not be less than eleven (11) days nor be more than fifteen (15) days after the delivery of the Provisional Exercise Notice.

(iv) Within ten (10) days of receipt of the Provisional Exercise Notice, the Warrantholder shall deliver written notice (the “Payment Method Election Notice”) to the Company as to whether it elects (in its sole discretion) to deliver the Exercise Price for the Shares issuable upon exercise of the Acceleration Option by the means set forth in Section 3(A)(ii)(a), the means set forth in Section 3(A)(ii)(b) or any combination thereof. In the event that the Company does not receive the Warrantholder’s Payment Method Election Notice within such ten (10) day period, the Warrantholder shall be deemed to have elected to deliver the Exercise Price by the means set forth in Section 3(A)(ii)(b).

(v) The issuance of the Shares upon exercise of the Acceleration Option shall occur on the date specified in the Provisional Exercise Notice or such other date mutually agreed to in writing by the Company and the Warrantholder (the “Deemed Exercise Date”) by surrender of the Warrant and delivery of the Exercise Price (if applicable) pursuant to the terms of this Section 3; provided, however, the Company is only obligated to issue Shares and the Warrantholder is only obligated to surrender the Warrant in respect of the exercise of the Acceleration Option if the arithmetic mean of the Market Price for the twenty (20) full Trading Days preceding the Deemed Exercise Date is greater than three times (3X) the Exercise Price.

(C) Unless otherwise waived in writing by the Warrantholder prior to the Expiration Time, in the event that this Warrant is not exercised prior to the Expiration

- 5 -

Time and provided that the Market Price of the Common Shares on each Approved Market in which Common Shares are listed for trading is greater than the Exercise Price, the Warrantholder shall be deemed to have exercised this Warrant as of the Expiration Time without any further action by the Warrantholder and shall be deemed to have elected payment of the Exercise Price pursuant to the means set forth in Section 3(A)(ii)(b). Thereupon, the Company shall promptly (and in any event within two (2) Business Days) deliver to the Warrantholder the Shares issuable upon such exercise and take any other action necessary to effect such issuance. For the avoidance of doubt, in no event shall the exercise of this Warrant pursuant to this Section 3(C) require any cash payment by the Warrantholder.

Section 4. U.S. Legends. Upon the original issuance thereof, and until such time as the same is no longer required under applicable requirements of the Securities Act or state securities laws, the certificates representing the Shares issuable upon the exercise of this Warrant, and all certificates issued in exchange therefor or in substitution thereof, shall bear on the face of such certificates the following legend:

Section 5. Issuance of Shares; Authorization; Listing; Reporting Issuer Status. Certificates for Shares issued upon exercise of this Warrant will be issued in such name or names as the Warrantholder may designate and will be delivered to such named Person or Persons within a reasonable time, not to exceed three (3) Business Days after the date on which this Warrant has been duly exercised in accordance with the terms of this Warrant. The Company hereby represents and warrants that any Shares issued upon the exercise of this Warrant in accordance with the provisions of Section 3 and all other provisions of this Warrant will be duly and validly authorized and issued, fully paid and nonassessable and free from all taxes, liens and charges (other than liens or charges created by the Warrantholder or taxes in respect of any transfer occurring contemporaneously therewith). The Company will at all times reserve and keep available out of its authorized but unissued Common Shares, solely for the purpose of providing for the exercise of this Warrant, the aggregate number of shares of Common Shares then issuable upon exercise of this Warrant. The Company will procure, at its sole expense, the listing of the Shares upon exercise of this Warrant, including but not limited to those Shares issuable pursuant to Section 13 of this Warrant, subject to issuance or notice of issuance on all stock exchanges on which the Common Shares are then listed or traded and maintain the listing of such Shares after issuance. The Company will use commercially reasonable efforts to ensure that the Shares may be issued without violation of any applicable law or regulation or of any requirement of any securities exchange, if any, on which the Shares are listed or traded. The Company shall make all requisite filings under applicable securities law and the respective

- 6 -

regulations made thereunder including those necessary to remain a reporting issuer not in default of any of the requirements of such laws and regulations.

Section 6. No Fractional Shares. No fractional Shares shall be issued upon any exercise of this Warrant. In lieu of any fractional Share to which the Warrantholder would otherwise be entitled, the Warrantholder shall be entitled to receive a cash payment equal to the Market Price of the Common Shares on the date of exercise less the Exercise Price for such fractional Share.

Section 7. No Rights as Shareholders; Transfer Books. This Warrant does not entitle the Warrantholder to any voting rights or other rights as a shareholder of the Company prior to the date of exercise hereof. The Company will at no time close its transfer books against transfer of this Warrant in any manner which interferes with the timely exercise of this Warrant.

Section 8. Charges, Taxes and Expenses. Issuance of certificates for Shares to the Warrantholder upon the exercise of this Warrant shall be made without charge to the Warrantholder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Company.

Section 9. Transfer/Assignment. (A) Subject to compliance with the Investment Agreement, applicable securities laws, and this Section 9, this Warrant and all rights hereunder are transferable, in whole or in part, by the Warrantholder in person or by duly authorized attorney by completing and delivering to the Company the transfer form attached hereto as Schedule “B”. Upon surrender of this Warrant, duly endorsed, to the office or agency of the Company described in Section 3, a new warrant shall be made and delivered by the Company, of the same tenor and date as this Warrant but registered in the name of the transferee. All expenses and other charges payable in connection with the preparation, execution and delivery of the new warrants pursuant to this Section 9 shall be paid by the Company.

Section 10. Exchange and Registry of Warrant. This Warrant is exchangeable, subject to applicable securities laws, upon the surrender hereof by the Warrantholder to the Company, for a new Warrant or new Warrants of like tenor and representing the right to purchase the same aggregate number of Shares. The Company shall maintain a registry showing the name and address of the Warrantholder as the registered holder of this Warrant. This Warrant may be surrendered for exchange or exercise, in accordance with its terms, at the office of the Company, and the Company shall be entitled to rely in all respects, prior to written notice to the contrary, upon such registry. All expenses and other charges payable in connection with the preparation, execution and delivery of the new warrants pursuant to this Section 10 shall be paid by the Company.

Section 11. Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and in the case of any such loss, theft or destruction, upon receipt of an indemnity or security satisfactory to the Company, acting reasonably, or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the Company shall make and deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant, a new warrant of like tenor

- 7 -

and representing the right to purchase the same aggregate number of Shares as provided for in such lost, stolen, destroyed or mutilated Warrant.

Section 12. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding day that is a Business Day.

Section 13. Adjustments and Other Rights. The Exercise Price and the number of Shares issuable upon exercise of this Warrant shall be subject to adjustment from time to time as follows; provided, that no single event shall be subject to adjustment under more than one sub-section of this Section 13 so as to result in duplication.

(A) Stock Splits, Subdivisions, Reclassifications or Combinations. If the Company shall (i) declare a stock dividend or make a distribution on its securities, in each case, in Common Shares, (ii) subdivide or reclassify the outstanding Common Shares into a greater number of shares, or (iii) combine or reclassify the outstanding Common Shares into a smaller number of shares, the number of Shares issuable upon exercise of this Warrant at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be proportionately adjusted so that the Warrantholder after such date shall be entitled to purchase the number of Common Shares which such holder would have owned or been entitled to receive after such date had this Warrant been exercised immediately prior to such date. In such event, the Exercise Price in effect at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be adjusted to the number obtained by dividing (x) the product of (1) the number of Shares issuable upon the exercise of this Warrant before such adjustment and (2) the Exercise Price in effect immediately prior to the record or effective date, as the case may be, for such dividend, distribution, subdivision, combination or reclassification giving rise to this adjustment by (y) the new number of Shares issuable upon exercise of this Warrant determined pursuant to the immediately preceding sentence.

(B) Other Distributions. In case the Company shall fix a record date for the making of a distribution to all holders of Common Shares (i) of shares of any class of Capital Stock other than its Common Shares, (ii) of evidence of indebtedness of the Company or any Subsidiary, (iii) of assets or cash (excluding dividends or distributions referred to in Section 13(A)), or (iv) of rights or warrants (other than in connection with the adoption of a stockholder rights plan), in each such case, the Exercise Price in effect prior thereto shall be reduced immediately thereafter to the price determined by dividing (x) an amount equal to the difference resulting from (1) the number of Common Shares outstanding on such record date multiplied by the Exercise Price on such record date, less (2) the Fair Market Value of said shares or evidences of indebtedness or assets or rights or warrants to be so distributed by (y) the number of Common Shares outstanding on such record date; such adjustment shall be made successively whenever such a record date is fixed. In such event, the number of Shares issuable upon the exercise of this Warrant shall be increased to the number obtained by dividing (x) the product of (1) the number of Shares issuable upon the exercise of this Warrant before such adjustment, and (2) the Exercise Price in effect immediately prior to the issuance giving rise to this adjustment by (y) the new Exercise Price determined in accordance with the immediately preceding sentence. In the event

- 8 -

that such distribution is not so made, the Exercise Price and the number of Shares issuable upon exercise of this Warrant then in effect shall be readjusted, effective as of the date when the Board determines not to distribute such shares, evidences of indebtedness, assets, rights or warrants, as the case may be, to the Exercise Price that would then be in effect and the number of Shares that would then be issuable upon exercise of this Warrant if such record date had not been fixed.

(C) Certain Repurchases of Common Shares. In case the Company effects a Pro Rata Repurchase of Common Shares, then the Exercise Price shall be reduced to the price determined by multiplying the Exercise Price in effect immediately prior to the effective date of such Pro Rata Repurchase by a fraction of which the numerator shall be (i) the product of (x) the number of Common Shares outstanding immediately before such Pro Rata Repurchase and (y) the Market Price of a Common Share on the Trading Day immediately preceding the first public announcement by the Company or any of its Affiliates of the intent to effect such Pro Rata Repurchase, minus (ii) the aggregate purchase price of the Pro Rata Repurchase, and of which the denominator shall be the product of (i) the number of Common Shares outstanding immediately prior to such Pro Rata Repurchase minus the number of Common Shares so repurchased and (ii) the Market Price per Common Share on the Trading Day immediately preceding the first public announcement of such Pro Rata Repurchase. In such event, the number of Common Shares issuable upon the exercise of this Warrant shall be increased to the number obtained by dividing (x) the product of (1) the number of Shares issuable upon the exercise of this Warrant before such adjustment, and (2) the Exercise Price in effect immediately prior to the Pro Rata Repurchase giving rise to this adjustment by (y) the new Exercise Price determined in accordance with the immediately preceding sentence. For the avoidance of doubt, no increase in the Exercise Price or reduction in the number of Shares issuable upon exercise of this Warrant shall be made pursuant to this Section 13(C).

(D) Rounding of Calculations. All calculations under this Section 13 shall be made to the nearest one-hundreth (1/100th) of a cent or to the nearest one-hundredth (1/100th) of a share, as the case may be.

(E) Timing of Issuance of Additional Shares Upon Certain Adjustments. In any case in which the provisions of this Section 13 shall require that an adjustment shall become effective immediately after a record date for an event, the Company may defer until the occurrence of such event (i) issuing to the Warrantholder of this Warrant exercised after such record date and before the occurrence of such event the additional Shares issuable upon such exercise by reason of the adjustment required by such event over and above the Shares issuable upon such exercise before giving effect to such adjustment and (ii) paying to such Warrantholder any amount of cash in lieu of a fractional Share; provided, however, that the Company upon request shall deliver to such Warrantholder a due xxxx or other appropriate instrument evidencing such Warrantholder’s right to receive such additional shares, and such cash, upon the occurrence of the event requiring such adjustment.

(F) Adjustment for Unspecified Actions. If the Company takes any action affecting the Common Shares, other than actions described in this Section 13, which in the opinion of the Board would adversely affect the exercise rights of the Warrantholder, the Exercise Price for the Warrant and/or the number of Shares received upon exercise of the Warrant shall be adjusted for the Warrantholder’s benefit, to the extent permitted by law, in such

- 9 -

manner, and at such time, as the Board after consultation with the Warrantholder shall reasonably determine to be equitable in the circumstances. Failure of the Board to provide for any such adjustment will be evidence that the Board has determined that it is equitable to make no such adjustments in the circumstances.

(G) Statement Regarding Adjustments. Whenever the Exercise Price or the number of Shares into which this Warrant is exercisable shall be adjusted as provided in Section 13 herein, the Company shall forthwith file at the principal office of the Company a statement showing in reasonable detail the facts requiring such adjustment and the Exercise Price that shall be in effect and the number of Shares issuable upon the exercise of this Warrant after such adjustment, and the Company shall also cause a copy of such statement to be sent by mail, first class postage prepaid, to each Warrantholder at the address appearing in the Company’s records.

(H) Notice of Adjustment Event. In the event that the Company shall propose to take any action of the type described in this Section 13 (but only if the action of the type described in this Section 13 would result in an adjustment in the Exercise Price or the number of Shares issuable upon the exercise of this Warrant or a change in the type of securities or property to be delivered upon exercise of this Warrant), the Company shall give notice to the Warrantholder, in the manner set forth in Section 13(G), which notice shall specify the record date, if any, with respect to any such action and the approximate date on which such action is to take place. Such notice shall also set forth the facts with respect thereto as shall be reasonably necessary to indicate the effect on the Exercise Price and the number, kind or class of shares or other securities or property which shall be deliverable upon exercise of this Warrant. In the case of any action which would require the fixing of a record date, such notice shall be given at least ten (10) days prior to the date so fixed, and in case of all other action, such notice shall be given at least fifteen (15) days prior to the taking of such proposed action. Failure to give such notice, or any defect therein, shall not affect the legality or validity of any such action.

(I) No Impairment. The Company will not, by amendment of its articles of incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in taking of all such action as may be necessary or appropriate in order to protect the rights of the Warrantholder.

(J) Adjustment Rules. Any adjustments pursuant to this Section 13 shall be made successively whenever an event referred to herein shall occur.

Section 14. Notice. Upon each determination of Market Price or Fair Market Value, as the case may be, hereunder, the Company shall promptly give notice thereof to the Warrantholder, setting forth in reasonable detail the calculation of such Market Price or Fair Market Value, and the method and basis of determination thereof, as the case may be.

Section 15. Governing Law. This Warrant shall be binding upon any successors or assigns of the Company. This Warrant shall constitute a contract under the laws of the Province of British Columbia and for all purposes shall be construed in accordance with and

- 10 -

governed by the laws of the Province of British Columbia and the federal laws of Canada applicable therein, without giving effect to its principles regarding conflicts of law. The Company hereby irrevocably submits to the jurisdiction of the courts of the Province of British Columbia.

Section 16. Attorneys’ Fees. In any litigation, arbitration or court proceeding between the Company and the Warrantholder as the holder of this Warrant relating hereto, the prevailing party shall be entitled to recover all of its reasonable attorneys’ fees and expenses incurred in enforcing this Warrant.

Section 17. Amendments. This Warrant may be amended and the observance of any term of this Warrant may be waived only, in the case of an amendment, with the written consent of the Company and the Warrantholder, or in the case of a waiver, by the party against whom the waiver is to be effective.

Section 18. Notices. All notices hereunder shall be in writing and shall be effective (A) on the day on which delivered if delivered personally or transmitted by facsimile with evidence of receipt, (B) one Business Day after the date on which the same is delivered to a nationally recognized overnight courier service with evidence of receipt, or (C) five Business Days after the date on which the same is deposited, postage prepaid, in the U.S. or Canadian mail, sent by certified or registered mail, return receipt requested, and addressed to the party to be notified at the address indicated below for the Company, or at the address for the Warrantholder set forth in the registry maintained by the Company pursuant to Section 10, or at such other address and/or telecopy or telex number and/or to the attention of such other person as the Company or the Warrantholder may designate by ten-day advance written notice. Notwithstanding the foregoing, the Provisional Exercise Notice sent in accordance with Section 3(B), shall be deemed effective on the date which the same is deposited, postage prepaid, in the U.S. mail.

If to the Company, any notice hereunder shall be sent to:

Attn: Chief Executive Officer

Facsimile: (000) 000-0000

Section 19. Prohibited Actions. The Company agrees that it will not take any action which would entitle the Warrantholder to an adjustment of the Exercise Price if the total number of Shares issuable after such action upon exercise of this Warrant, together with all Common Shares then outstanding and all Common Shares then issuable upon the exercise of all outstanding options, warrants, conversion and other rights, would exceed the total number of Common Shares then authorized by its certificate of incorporation. In furtherance of and without limiting the foregoing, as a condition precedent to the taking of any action which would require an adjustment pursuant to Section 13, the Company shall take any action which may be necessary, including obtaining regulatory or shareholder approvals or exemptions, in order that

- 11 -

the Company may thereafter validly and legally issue as fully paid and non-assessable all Shares that the Warrantholder is entitled to receive upon exercise of this Warrant.

Section 20. Currency. All references to currency in this Warrant are denominated in Canadian dollars.

ARTICLE II

REGISTRATION RIGHTS SECTION

SECTION 2.01. Demand Registration.

(a) Demand by WP. At any time after the Effective Date, WP (a “Demand Party”) may, subject to Section 2. 10, make a written request (a “Demand Notice”) to the Company for Registration of all or part of the Registrable Securities held by such Demand Party (i) on Form S-1 or F-1 in the United States or pursuant to Canadian securities legislation applicable for long form prospectuses in Canada (a “Long-Form Registration”); (ii) on Form S-3 or Form F-3 in the United States or pursuant to Canadian securities legislation applicable to short

form prospectuses in Canada (a “Short-Form Registration”) if the Company qualifies to use such short form or (iii) any other form permitted by the Multijurisdictional Disclosure System and selected by the Demand Party in its sole discretion (a “Multijurisdicational Registration” and together with a Long-Form Registration, Short-Form Registration, a “Demand Registration”). Each Demand Notice shall specify the aggregate amount of Registrable Securities of the Demand Party to be registered and the intended methods of disposition thereof. Subject to Section 2. 10, after delivery of such Demand Notice, the Company (x) shall file promptly (and, in any event, within (i) ninety (90) days in the case of a request for a Long-Form Registration or (ii) thirty (30) days in the case of a request for a Short-Form Registration, in each case, following delivery of such Demand Notice) with the SEC and/or the applicable Commission(s) a Registration Statement and/or Canadian Prospectus, as applicable, relating to such Demand Registration (a “Demand Registration Statement”), and (y) shall use its reasonable best efforts to cause such Demand Registration Statement to promptly be declared effective under (x) the Securities Act; (y) the “Blue Sky” laws of such jurisdictions reasonably requested by the Participating Holder and (z), if applicable, Canadian securities legislation, as any Participating Holder or any underwriter, if any, reasonably requests. The Company shall not be obligated to effect, or to take any action to effect, any such registration pursuant to this Section 2.1 if the Demand Party, together with the holders of any other securities of the Company entitled to inclusion in such registration statement, propose to sell Registrable Securities and such other securities (if any) and the aggregate proceeds of which (after deduction for underwriter’s discounts and expenses related to the issuance) are less than $5,000,000 or 100% of the Registrable Securities then held by WP.

(b) Demand Withdrawal. A Demand Party may withdraw its Registrable Securities from a Demand Registration at any time prior to the effectiveness of the applicable Demand Registration Statement. Upon delivery of a notice by the Demand Party to such effect, the Company shall cease all efforts to secure effectiveness of the applicable Demand Registration Statement, and such Registration shall not be deemed to be a Demand Registration with respect to such Demand Party for purposes of Section 2.10.

(c) Effective Registration. The Company shall be deemed to have effected a Demand Registration with respect to the Demand Party for purposes of Section 2.10 if the Demand Registration Statement is declared effective by the SEC and remains effective for not less than 180 days (or such shorter period as shall terminate when all Registrable Securities covered by such Registration Statement or Canadian Prospectus have been sold or withdrawn) or a receipt has been issued for the final Canadian Prospectus by the applicable Commission(s), as applicable, or if such Registration Statement and/or Canadian Prospectus relates to an Underwritten Offering, such longer period as, in the opinion of counsel for the underwriter or underwriters, a Prospectus is required by law to be delivered in connection with sales of Registrable Securities by an underwriter or dealer (the applicable period, the “Demand Period”). No Demand Registration shall be deemed to have been effected for purposes of Section 2.10 if (i) during the Demand Period such Registration is interfered with by any stop order, injunction or other order or requirement of the SEC, the Commissions or other governmental agency or court or (ii) the conditions to closing specified in the underwriting agreement, if any, entered into in connection with such Registration are not satisfied other than by reason of a wrongful act, misrepresentation or breach of such applicable underwriting agreement by a Demand Party.

(d) Delay in Filing; Suspension of Registration. If the Company shall furnish to the Participating Holders a certificate signed by the Chief Executive Officer or equivalent senior executive officer of the Company stating that the filing, effectiveness or continued use of a Demand Registration Statement would require the Company to make an Adverse Disclosure, then the Company may delay the filing (but not the preparation of) or initial effectiveness of, or suspend use of, the Demand Registration Statement (a “Demand Suspension”); provided, however, that the Company, unless otherwise approved in writing by WP, shall not be permitted to exercise aggregate Demand Suspensions and Shelf Suspensions more than twice, or for more than an aggregate of 90 days, in each case, during any 12-month period; provided further that in the event of a Demand Suspension, such Demand Suspension shall terminate at such earlier time as the Company would no longer be required to make any Adverse Disclosure. Each Participating Holder shall keep confidential the fact that a Demand Suspension is in effect, the certificate referred to above and its contents unless and until otherwise notified by the Company, except (A) for disclosure to such Participating Holder’s employees, agents and professional advisers who reasonably need to know such information for purposes of assisting the Participating Holder with respect to its investment in the Company Shares and agree to keep it confidential, (B) for disclosures to the extent required in order to comply with reporting obligations to its limited partners or other direct or indirect investors who have agreed to keep such information confidential, (C) if and to the extent such matters are publicly disclosed by the Company or any of its Subsidiaries or any other Person that, to the actual knowledge of such Participating Holder, was not subject to an obligation or duty of confidentiality to the Company and its Subsidiaries and (D) as required by law, rule or regulation. In the case of a Demand Suspension, the Participating Holders agree to suspend use of the applicable Canadian Prospectus, Prospectus and any Issuer Free Writing Prospectus in connection with any sale or purchase of, or offer to sell or purchase, Registrable Securities, upon delivery of the notice referred to above. The Company shall immediately notify the Participating Holders upon the termination of any Demand Suspension, amend or supplement the Canadian Prospectus, Prospectus and any Issuer Free Writing Prospectus, if necessary, so it does not contain any untrue statement or omission and furnish to the Participating Holders such numbers of copies of the Canadian Prospectus, Prospectus and any Issuer Free Writing Prospectus as so amended or supplemented as the Participating Holders may reasonably request. The Company agrees, if necessary, to supplement or make amendments to the Demand Registration Statement if required by the registration form used by the Company for the applicable Registration or by the instructions applicable to such registration form or by the Securities Act or the rules or regulations promulgated thereunder or applicable Canadian securities legislation, or as may reasonably be requested by any Demand Party.

(e) Underwritten Offering. If a Demand Party so requests, an offering of Registrable Securities pursuant to a Demand Registration shall be in the form of an Underwritten Offering, and such Demand Party shall have the right to select the managing underwriter or underwriters to administer the offering. If the Demand Party intends to sell the Registrable Securities covered by its demand by means of an Underwritten Offering, such Demand Party shall so advise the Company as part of its Demand Notice.

(f) Priority of Securities Registered Pursuant to Demand Registrations. If the managing underwriter or underwriters of a proposed Underwritten Offering of the Registrable Securities included in a Demand Registration advise the Board of Directors in writing that, in its

or their opinion, the number of securities requested to be included in such Demand Registration exceeds the number which can be sold in such offering without being likely to have a significant adverse effect on the price, timing or distribution of the securities offered or the market for the securities offered, the securities to be included in such Demand Registration (i) first, shall be allocated pro rata among the Institutional Investors that have requested to participate in such Demand Registration based on the relative number of Registrable Securities then held by each such Institutional Investor (provided that any securities thereby allocated to an Institutional Investor that exceed such Institutional Investor’s request shall be reallocated among the remaining requesting Institutional Investors in like manner), and (ii) second, and only if all the securities referred to in clause (i) have been included in such Registration, the number of securities that the Company proposes to include in such Registration that, in the opinion of the managing underwriter or underwriters, can be sold without having such adverse effect and (iii) third, and only if all of the securities referred to in clause (ii) have been included in such Registration, any other securities eligible for inclusion in such Registration that, in the opinion of the managing underwriter or underwriters, can be sold without having such adverse effect.

SECTION 2.02. Shelf Registration.

(a) Filing. At any time after the Effective Date, WP may, subject to Section 2.10, make a written request (a “Shelf Notice”) to the Company to file a Shelf Registration Statement or Canadian Shelf Prospectus, which Shelf Notice shall specify whether such Registration shall be a Long-Form Registration or, if the Company so qualifies, a Short-Form Registration or Multijurisdicational Registration, the aggregate amount of Registrable Securities of WP to be registered therein and the intended methods of distribution thereof. Following the delivery of a Shelf Notice, the Company (x) shall file promptly (and, in any event, within (i) ninety (90) days in the case of a request for a Long-Form Registration or (ii) thirty (30) days in the case of a request for a Short-Form Registration, in each case, following delivery of such Shelf Notice) with the SEC such Shelf Registration Statement (which shall be an automatic Shelf Registration Statement if the Company qualifies at such time to file such a Shelf Registration Statement) and, if applicable, with the relevant Commissions such Canadian Shelf Prospectus, relating to the offer and sale of all Registrable Securities requested for inclusion therein by WP. If, on the date of any such request, the Company does not qualify to file a Shelf Registration Statement under the Securities Act or, if applicable, a Canadian Shelf Prospectus, the provisions of this Section 2.02 shall not apply, and the provisions of Section 2.01 shall apply instead.

(b) Continued Effectiveness. The Company shall use its reasonable best efforts to keep any Shelf Registration Statement or Canadian Shelf Prospectus filed pursuant to Section 2.02(a) continuously effective under the Securities Act and, if applicable, Canadian securities law in order to permit the Prospectus or, if applicable, the Canadian Shelf Prospectus forming a part thereof to be usable by Shelf Holders until the earliest of (i) the date as of which all Registrable Securities have been sold pursuant to the Shelf Registration Statement or another Registration Statement filed under the Securities Act (but in no event prior to the applicable period referred to in Section 4(3) of the Securities Act and Rule 174 thereunder) or, if applicable, a Canadian Prospectus or Canadian Shelf Prospectus filed under Canadian securities legislation, (ii) the date as of which each of the Shelf Holders is permitted to sell its Registrable Securities without Registration in the U.S. pursuant to Rule 144 (with respect to a U.S. Registration) or similar legislation in Canada (with respect to a Canadian Registration) without volume limitation

or other restrictions on transfer thereunder, assuming, for purposes of this clause (ii), that such Shelf Holder is an Affiliate of Company and (iii) such shorter period as WP with respect to such Shelf Registration and/or Canadian Shelf Prospectus shall agree in writing (such period of effectiveness, the “Shelf Period”). Subject to Section 2.02(c), the Company shall not be deemed to have used its reasonable best efforts to keep the Shelf Registration Statement and/or Canadian Shelf Prospectus effective during the Shelf Period if the Company voluntarily takes any action or omits to take any action that would result in WP not being able to offer and sell any Registrable Securities pursuant to such Shelf Registration Statement and/or Canadian Shelf Prospectus during the Shelf Period, unless such action or omission is (x) a Shelf Suspension permitted pursuant to Section 2.02(c) or (y) required by applicable law, rule or regulation.

(c) Suspension of Registration. If the Company shall furnish to the Shelf Holders a certificate signed by the Chief Executive Officer or equivalent senior executive officer of the Company stating that the continued use of a Shelf Registration Statement or Canadian Shelf Prospectus filed pursuant to Section 2.02(a) would require the Company to make an Adverse Disclosure, then the Company may suspend use of the Shelf Registration Statement or Canadian Shelf Prospectus (a “Shelf Suspension”); provided, however, that the Company, unless otherwise approved in writing by WP, shall not be permitted to exercise aggregate Demand Suspensions and Shelf Suspensions more than twice, or for more than an aggregate of 90 days, in each case, during any 12-month period; provided further that in the event of a Shelf Suspension, such Shelf Suspension shall terminate at such earlier time as the Company would no longer be required to make any Adverse Disclosure. Each Shelf Holder shall keep confidential the fact that a Shelf Suspension is in effect, the certificate referred to above and its contents unless and until otherwise notified by the Company, except (A) for disclosure to such Shelf Holder’s employees, agents and professional advisers who reasonably need to know such information for purposes of assisting the Holder with respect to its investment in the Company Shares and agree to keep it confidential, (B) for disclosures to the extent required in order to comply with reporting obligations to its limited partners or other direct or indirect investors who have agreed to keep such information confidential, (C) if and to the extent such matters are publicly disclosed by the Company or any of its Subsidiaries or any other Person that, to the actual knowledge of such Shelf Holder, was not subject to an obligation or duty of confidentiality to the Company and its Subsidiaries and (D) as required by law, rule or regulation. In the case of a Shelf Suspension, the Shelf Holders agree to suspend use of the applicable Canadian Shelf Prospectus, Prospectus and any Issuer Free Writing Prospectus in connection with any sale or purchase of, or offer to sell or purchase, Registrable Securities, upon delivery of the notice referred to above. The Company shall immediately notify the Shelf Holders upon the termination of any Shelf Suspension, amend or supplement the applicable Canadian Shelf Prospectus, Prospectus and any Issuer Free Writing Prospectus, if necessary, so it does not contain any untrue statement or omission and furnish to the Shelf Holders such numbers of copies of the applicable Canadian Shelf Prospectus, Prospectus and any Issuer Free Writing Prospectus as so amended or supplemented as the Shelf Holders may reasonably request. The Company agrees, if necessary, to supplement or make amendments to the Shelf Registration Statement and, if applicable, Canadian Shelf Prospectus, if required by the registration form used by the Company for the applicable Registration or by the instructions applicable to such registration form or by the Securities Act or the rules or regulations promulgated thereunder or by applicable Canadian securities legislation, or as may reasonably be requested by WP.

(d) Shelf Take-Downs.

(i) An offering or sale of Registrable Securities pursuant to a Shelf Registration Statement and/or Canadian Shelf Prospectus (a “Shelf Take-Down”) may be initiated by WP (an “Initiating Shelf Take-Down Holder”).

(ii) Subject to Section 2. 10, if the Initiating Shelf Take-Down Holder elects by written request to the Company, a Shelf Take-Down shall be in the form of an Underwritten Offering (an “Underwritten Shelf Take-Down Notice”) and the Company shall amend or supplement the Shelf Registration Statement and/or Canadian Shelf Prospectus for such purpose as soon as practicable. Such Initiating Shelf Take-Down Holder shall have the right to select the managing underwriter or underwriters to administer such offering. The provisions of Section 2.01(f) shall apply to any Underwritten Offering pursuant to this Section 2.02(d).

SECTION 2.03. Piggyback Registration.

(a) Participation. If the Company at any time proposes to file a Registration Statement and/or Canadian Prospectus with respect to any offering of its equity securities for its own account or for the account of any other Persons (other than (i) a Registration under Section 2.01 or 2.02, it being understood that this clause (i) does not limit the rights of WP to make written requests pursuant to Sections 2.01 or 2.02 or otherwise limit the applicability thereof, (ii) a Registration Statement on Form S-4, F-4 or S-8 (or such other similar successor forms then in effect under the Securities Act), (iii) a registration of securities solely relating to an offering and sale to employees, directors or consultants of the Company or its Subsidiaries pursuant to any employee stock plan or other employee benefit plan arrangement, (iv) a registration not otherwise covered by clause (ii) above pursuant to which the Company is offering to exchange its own securities for other securities, (v) a Registration Statement relating solely to dividend reinvestment or similar plans or (vi) a Shelf Registration Statement or Canadian Shelf Prospectus pursuant to which only the initial purchasers and subsequent transferees of debt securities of the Company or any of its Subsidiaries that are convertible or exchangeable for Company Shares and that are initially issued pursuant to Rule 144A and/or Regulation S (or any successor provisions) of the Securities Act or similar private placement provisions under Canadian securities legislation may resell such notes and sell the Company Shares into which such notes may be converted or exchanged) (a “Company Public Sale”), then, as soon as practicable (but in no event less than 30 days prior to the proposed date of filing of such Registration Statement and/or Canadian Prospectus, unless the filing is in connection with an overnight bought deal or overnight marketed offering, in which case the notice shall be not less than one (1) Business Day), the Company shall give written notice of such proposed filing to the Institutional Investors, and such notice shall offer the Institutional Investors the opportunity to Register under such Registration Statement and/or Canadian Prospectus such number of Registrable Securities as the Institutional Investors may request in writing delivered to the Company within ten (10) days of delivery of such written notice by the Company. Subject to Sections 2.03(b) and (c), the Company shall include in such Registration Statement and/or Canadian Prospectus all such Registrable Securities that are requested by the Institutional Investors to be included therein in compliance with the immediately foregoing sentence (a “Piggyback Registration”); provided that if at any time after giving written notice of its intention to Register any equity securities and

prior to the effective date of the Registration Statement and/or Canadian Prospectus filed in connection with such Piggyback Registration, the Company shall determine for any reason not to Register or to delay Registration of the equity securities covered by such Piggyback Registration, the Company shall give written notice of such determination to each Institutional Investor to the extent the Institutional Investor requested to Register its Registrable Securities in such Registration Statement and/or Canadian Prospectus and, thereupon, (1) in the case of a determination not to Register, shall be relieved of its obligation to Register any Registrable Securities in connection with such Registration (but not from its obligation to pay the Registration Expenses in connection therewith, to the extent payable), without prejudice, however, to the rights of WP to request that such Registration be effected as a Demand Registration under Section 2.01, and (2) in the case of a determination to delay Registering, in the absence of a request by WP to request that such Registration be effected as a Demand Registration under Section 2.01, shall be permitted to delay Registering any Registrable Securities, for the same period as the delay in Registering the other equity securities covered by such Piggyback Registration. If the offering pursuant to such Registration Statement and/or Canadian Prospectus is to be underwritten, the Company shall so advise the Institutional Investors as a part of the written notice given pursuant this Section 2.03(a), and to the extent an Institutional Investor makes a request for a Piggyback Registration pursuant to this Section 2.03(a), such Institutional Investor must, and the Company shall make such arrangements with the managing underwriter or underwriters so that such Institutional Investors may, participate in such Underwritten Offering, subject to the conditions of Section 2.03(b) and (c). If the offering pursuant to such Registration Statement and/or Canadian Prospectus is to be on any other basis, the Company shall so advise the Institutional Investors as part of the written notice given pursuant to this Section 2.03(a), and to the extent an Institutional Investor makes a request for a Piggyback Registration pursuant to this Section 2.03 (a), the Company shall make such arrangements so that such Institutional Investor may participate in such offering on such basis, subject to the conditions of Section 2.03(b) and (c). Each Institutional Investor shall be permitted to withdraw all or part of its Registrable Securities from a Piggyback Registration at any time prior to the effectiveness of such Registration Statement and/or Canadian Prospectus.

(b) Priority of Piggyback Registration. If the managing underwriter or underwriters of any proposed Underwritten Offering of Registrable Securities included in a Piggyback Registration informs the Company and, to the extent an Institutional Investor makes a request to participate in such Piggyback Registration in writing, each such Institutional Investor that, in its or their opinion, the number of securities which the Institutional Investors and any other Persons intend to include in such offering exceeds the number which can be sold in such offering without being likely to have a significant adverse effect on the price, timing or distribution of the securities offered or the market for the securities offered, then the securities to be included in such Registration shall be (i) first, 100% of the securities that the Company or (subject to Section 2.06) any Person (other than the Institutional Investors) exercising a contractual right to demand Registration, as the case may be, proposes to sell, (ii) second, and only if all the securities referred to in clause (i) have been included, the number of Registrable Securities that, in the opinion of such managing underwriter or underwriters, can be sold without having such adverse effect in such Registration, which such number shall be allocated pro rata among the Institutional Investors that have requested to participate in such Registration based on the relative number of Registrable Securities then held by each such Institutional Investor (provided that any securities thereby allocated to an Institutional Investor that exceed such

Institutional Investor’s request shall be reallocated among the remaining requesting Institutional Investors in like manner), and (iii) third, and only if all of the Registrable Securities referred to in clause (ii) have been included in such Registration, any other securities eligible for inclusion in such Registration that, in the opinion of the managing underwriter or underwriters, can be sold without having such adverse effect in such Registration.

(c) No Effect on Demand Registrations. No Registration of Registrable Securities effected pursuant to a request under this Section 2.03 shall be deemed to have been effected pursuant to Sections 2.01 or 2.02 or shall relieve the Company of its obligations under Sections 2.01 or 2.02.

(provided that in such instance the Company shall not be so liable if it has undertaken its reasonable best efforts to so register or qualify such Registrable Securities) or (v) any actions or inactions or proceedings in respect of the foregoing whether or not such indemnified party is a party thereto, and the Company will reimburse, as incurred, each such Holder and each of their respective direct or indirect partners, members or shareholders and each of such partner’s, member’s or shareholder’s partners members or shareholders and, with respect to all of the foregoing Persons, each of their respective Affiliates, employees, directors, officers, trustees or agents and controlling Persons and each of their respective Representatives, for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action; provided, that the Company shall not be liable to any particular indemnified party to the extent that any such Loss arises out of or is based upon (A) an untrue statement or alleged untrue statement or omission or alleged omission made in any such Registration Statement or Canadian Prospectus or other document in reliance upon and in conformity with written information furnished to the Company by such indemnified party expressly for use in the preparation thereof or (B) an untrue statement or omission in a preliminary Prospectus or Canadian Prospectus relating to Registrable Securities, if a Prospectus or Canadian Prospectus (as then amended or supplemented) that would have cured the defect was furnished to the indemnified party from whom the Person asserting the claim giving rise to such Loss purchased Registrable Securities at least five (5) days prior to the written confirmation of the sale of the Registrable Securities to such Person and a copy of such Prospectus or Canadian Prospectus (as amended and supplemented) was not sent or given by or on behalf of such indemnified party to such Person at or prior to the written confirmation of the sale of the Registrable Securities to such Person.

The Company shall also indemnify underwriters, selling brokers, dealer managers and similar securities industry professionals participating in the distribution, their officers and directors and each ‘control person’ (within the meaning of applicable Canadian securities legislation) and each Person who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above with respect to the indemnification of the indemnified parties.

(b) Indemnification by the Participating Holders. Each Participating Holder agrees (severally and not jointly) to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors and officers and each ‘control person’ (within the meaning of applicable Canadian securities legislation) and each Person who controls the Company (within the meaning of the Securities Act or the Exchange Act), and each other Holder, each of such other Holder’s respective direct or indirect partners, members or shareholders and each of such partner’s, member’s or shareholder’s partners members or shareholders and, with respect to all of the foregoing Persons, each of their respective Affiliates, employees, directors, officers, trustees or agents and each ‘control person’ (within the meaning of applicable Canadian securities legislation) and each Person who controls (within the meaning of the Securities Act or the Exchange Act) such Persons and each of their respective Representatives from and against any Losses resulting from (i) any untrue statement of a material fact in any Canadian Prospectus or Registration Statement under which such Registrable Securities were Registered under applicable Canadian securities legislation or the Securities Act (including any final, preliminary or summary Prospectus contained therein or any amendment or supplement thereto or any

documents incorporated by reference therein) or any Issuer Free Writing Prospectus or amendment or supplement thereto, or (ii) any omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, preliminary Prospectus or Issuer Free Writing Prospectus, in light of the circumstances under which they were made) not misleading, in each case to the extent, but only to the extent, that such untrue statement or omission is contained in any information furnished in writing by such Holder to the Company specifically for inclusion in such Registration Statement or Canadian Prospectus and has not been corrected in a subsequent writing prior to or concurrently with the sale of the Registrable Securities to the Person asserting the claim, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) was made in such Canadian Prospectus, Registration Statement, prospectus, offering circular, Issuer Free Writing Prospectus or other document, in reliance upon and in conformity with written information furnished to the Company by such Holder expressly for use therein. In no event shall the liability of such Holder hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder under the sale of Registrable Securities giving rise to such indemnification obligation.

(c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification under this Section 2.08 shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that any delay or failure to so notify the indemnifying party shall relieve the indemnifying party of its obligations hereunder only to the extent, if at all, that it is actually and materially prejudiced by reason of such delay or failure) and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided that any Person entitled to indemnification hereunder shall have the right to select and employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such Person unless (A) the indemnifying party has agreed in writing to pay such fees or expenses, (B) the indemnifying party shall have failed to assume the defense of such claim within a reasonable time after delivery of notice of such claim from the Person entitled to indemnification hereunder and employ counsel reasonably satisfactory to such Person, (C) the indemnified party has reasonably concluded (based upon advice of its counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, or (D) in the reasonable judgment of any such Person (based upon advice of its counsel) a conflict of interest may exist between such Person and the indemnifying party with respect to such claims (in which case, if the Person notifies the indemnifying party in writing that such Person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such Person). If the indemnifying party assumes the defense, the indemnifying party shall not have the right to settle such action, consent to entry of any judgment or enter into any settlement, in each case without the prior written consent of the indemnified party, unless the entry of such judgment or settlement (i) includes as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of an unconditional release from all liability in respect to such claim or litigation and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of such indemnified party, and provided that any sums payable in connection with such settlement are paid in full by the indemnifying party. If such defense is not assumed by the indemnifying party, the indemnifying party will not be subject to any liability for any settlement made without its prior

written consent, but such consent may not be unreasonably withheld. It is understood that the indemnifying party or parties shall not, except as specifically set forth in this Section 2.08(c), in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements or other charges of more than one separate firm admitted to practice in such jurisdiction at any one time unless (x) the employment of more than one counsel has been authorized in writing by the indemnifying party or parties, (y) an indemnified party has reasonably concluded (based on the advice of counsel) that there may be legal defenses available to it that are different from or in addition to those available to the other indemnified parties, or (z) a conflict or potential conflict exists or may exist (based upon advice of counsel to an indemnified party) between such indemnified party and the other indemnified parties, in each of which cases the indemnifying party shall be obligated to pay the reasonable fees and expenses of such additional counsel or counsels.

(d) Contribution. If for any reason the indemnification provided for in paragraphs (a) and (b) of this Section 2.08 is unavailable to an indemnified party or insufficient in respect of any Losses referred to therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and the indemnified party or parties on the other hand in connection with the acts, statements or omissions that resulted in such losses, as well as any other relevant equitable considerations. In connection with any Registration Statement filed with the SEC by the Company or Canadian Prospectus filed with a Commission, the relative fault of the indemnifying party on the one hand and the indemnified party on the other hand shall be determined by reference to, among other things, whether any 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 the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just or equitable if contribution pursuant to this Section 2.08(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 2.08(d). No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act or similar provision in Canadian securities legislation) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The amount paid or payable by an indemnified party as a result of the Losses referred to in Sections 2.08(a) and 2.08(b) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 2.08(d), in connection with any Registration Statement or Canadian Prospectus filed by the Company, a Participating Holder shall not be required to contribute any amount in excess of the dollar amount of the net proceeds received by such Holder under the sale of Registrable Securities giving rise to such contribution obligation less any amount paid by such Holders pursuant to Section 2.08(b). If indemnification is available under this Section 2.08, the indemnifying parties shall indemnify each indemnified party to the full extent provided in Sections 2.08(a) and 2.08(b) hereof without regard to the provisions of this Section 2.08(d).

(e) No Exclusivity. The remedies provided for in this Section 2.08 are not exclusive and shall not limit any rights or remedies which may be available to any indemnified party at law or in equity or pursuant to any other agreement.

(f) Survival. The indemnities provided in this Section 2.08 shall survive the transfer of any Registrable Securities by such Holder.

SECTION 2.09. Rules 144 and 144A and Regulation S and Canadian Private Placements.

The Company covenants that it will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder and applicable Canadian securities legislation (or, if the Company is not required to file such reports, it will, upon the reasonable request of WP, make publicly available such necessary information for so long as necessary to permit sales pursuant to Rules 144, 144A (if applicable) or Regulation S under the Securities Act (assuming for this purpose that all Holders are Affiliates of the Company) or private placement rules under Canadian securities legislation), and it will take such further action as WP may reasonably request, all to the extent required from time to time to enable the Holders, following the Effective Date, to sell Registrable Securities without Registration under the Securities Act or Canadian securities legislation within the limitation of the exemptions provided by (i) Rules 144, 144A (if applicable) or Regulation S under the Securities Act, as such Rules may be amended from time to time, or (ii) any similar rule or regulation hereafter adopted by the SEC or (iii) applicable Canadian securities legislation. Upon the reasonable request of a Holder, the Company will deliver to such Holder a written statement as to whether it has complied with such requirements and, if not, the specifics thereof.

SECTION 2.10. Limitation on Registrations and Underwritten Offerings.

(a) Notwithstanding the rights and obligations set forth in Sections 2.01 and 2.02, in no event shall the Company be obligated to take any action to effect any Demand Registration or any Marketed Underwritten Shelf Take-Down at the request of WP (and its Affiliates and Permitted Assignees) after the Company has effected such number of Demand Registrations and/or Marketed Underwritten Shelf Take-Downs at the request of WP and its Affiliates and Permitted Assignees equal to the number of WP Registration Demands; provided, however, that the first Marketed Underwritten Shelf Take-Down initiated by WP (or its Affiliates and Permitted Assignees) from any Shelf Registration Statement or Canadian Shelf Prospectus previously requested by WP (or its Affiliates and Permitted Assignees), shall not be deemed to be, solely for purposes of this Section 2.10(a), a Marketed Underwritten Shelf Take-Down.

(b) Notwithstanding the rights and obligations set forth in Sections 2.01 and 2.02, in no event shall the Company be obligated to take any action to (i) effect more than one Marketed Underwritten Offering in any consecutive 90-day period or (ii) effect any Underwritten Offering unless WP proposes to sell Registrable Securities in such Underwritten Offering having a reasonably anticipated gross aggregate price (before deduction of underwriter commissions and offering expenses) of at least $5,000,000 or 100% of the Registrable Securities then held by WP (if the value of such Registrable Securities is reasonably anticipated to have a gross aggregate price of less than $5,000,000).

(c) For purposes of this Agreement: “WP Registration Demands” means five (5); provided, however, that with respect to Registrations pursuant to Section 2.02(a), if the Company is eligible to file a Short Form Registration, such Short Form Registrations shall not be limited and shall not count as one of the five (5) WP Registration Demands for purposes of Section 2.10(a).

SECTION 2.11. Clear Market.

(a) With respect to any Underwritten Offerings of Registrable Securities by WP, the Company agrees not to effect (other than pursuant to the Registration applicable to such Underwritten Offering or pursuant to a Special Registration) any public sale or distribution, or to file any Registration Statement or Canadian Prospectus (other than pursuant to the Registration applicable to such Underwritten Offering or pursuant to a Special Registration) covering any of its equity securities or any securities convertible into or exchangeable or exercisable for such securities, during the period not to exceed ten (10) days prior and sixty (60) days following the effective date of such offering or such longer period up to ninety (90) days as may be requested by the managing underwriter for such Underwritten Offering. “Special Registration” means the registration of (A) equity securities and/or options or other rights in respect thereof solely registered on Form S-4,F-4 or Form S-8 (or successor form) or (B) shares of equity securities and/or options or other rights in respect thereof to be offered to directors, employees, consultants, customers, lenders or vendors of the Company or its Subsidiaries or in connection with dividend reinvestment plans.

(b) Each Holder hereby agrees that such Holder shall not sell or otherwise transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, of any Company Shares (or other securities) of the Company held by such Holder (other than those included in the Registration) during the one hundred eighty (180) day period following the effective date of the Company’s first Registration Statement filed under the Securities Act (or such other period as may be requested by the Company or an underwriter to accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4), or any successor provisions or amendments thereto) provided that: all officers and directors of the Company and holders of at least five percent (5%) of the Company’s voting securities are bound by and have entered into similar agreements. Provided, however, the forgoing restrictions shall be subject to any exceptions set forth in the market standoff agreement contemplated below. The obligations described in this Section 2.11 shall not apply to a registration relating solely to employee benefit plans on Form S-l, Form F-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4, Form F-4or similar forms that may be promulgated in the future. Each Holder agrees to execute a market standoff agreement with said underwriters in customary form consistent with the provisions of this Section 2.11.

SECTION 2.12. In-Kind Distributions.

If any Holder seeks to effect an in-kind distribution of all or part of its Company Shares to its direct or indirect equityholders, the Company will reasonably cooperate with and

assist such Holder, such equityholders and the Company’s transfer agent to facilitate such in-kind distribution in the manner reasonably requested by such Holder (including the delivery of instruction letters by the Company or its counsel to the Company’s transfer agent, the delivery of customary legal opinions by counsel to the Company and the delivery of Company Shares without restrictive legends, to the extent no longer applicable).

ARTICLE III

This Agreement shall terminate (a) with respect to a Holder in connection with U.S. Registrations, after the Effective Date (as it relates to a U.S. Registration), if such Holder beneficially owns less than five percent (5%) of the Company’s outstanding Company Shares and all of the Registrable Securities then owned by such Holder could be sold in any ninety (90)- day period pursuant to Rule 144 (assuming for this purpose that such Holder is an Affiliate of the Company), (b) with respect to a Holder in connection with Canadian Registrations, after the Effective Date (as it relates to a Canadian Registration), if such Holder and its Affiliates beneficially own less than five percent (5%) of the Company’s outstanding Common Shares (in the aggregate), or (c) with respect to a Holder, if all of the Registrable Securities held by such Holder have been sold in a Registration pursuant to the Securities Act or Canadian securities legislation or pursuant to an exemption therefrom.

Re: Priority of Indemnification Obligations

Ladies and Gentlemen:

Reference is made to that certain Investment Agreement, dated as of September 28, 2010 (as the same may be amended from time to time, the “Investment Agreement”), by and among Protox Therapeutics Inc., a British Columbia corporation (the “Company”) and you and to the several indemnification agreements, dated as of the date hereof, by and between the Company and certain individuals who have agreed to serve as directors of the Company (each a “Purchaser Designee”) (as such indemnification agreements may be amended from time to time and including any additional agreement or documents providing for indemnification of any Purchaser Designees by the Company that may exist in the future, collectively, the “Indemnification Agreements”). All initially capitalized terms used herein and not otherwise defined herein shall have the meanings set forth in the Indemnification Agreements or the Investment Agreement, as applicable.

The Company hereby acknowledges that, in addition to the rights provided to the Purchaser Designees pursuant to the Indemnification Agreements and the Articles of the Company (the “Articles”) (as beneficiaries of such rights, each Purchaser Designee is herein referred to as a “WP Director Indemnitee”), the WP Director Indemnitees may have certain rights to indemnification and/or advancement of expenses provided by, and/or insurance obtained by, Warburg Pincus Private Equity X, L.P., Warburg Pincus X Partners, L.P. and/or certain of their affiliates, whether now or in the future (collectively, the “Fund Indemnitors”, and the “Fund Indemnity Rights” ). Notwithstanding anything to the contrary in any of the Indemnification Agreements or the Investment Agreement, the Company hereby agrees that, with respect to its indemnification and advancement obligations to the WP Director Indemnitees under the Indemnification Agreements, the Articles, or otherwise, the Company (i) is the indemnitor of first resort (i.e., its obligations to indemnify the WP Director Indemnitees are primary and any obligation of the Fund Indemnitors or their insurers to advance expenses or to provide indemnification for the same expenses or liabilities incurred by any of the WP Director

Indemnitees is secondary and excess), (ii) shall be required to advance the full amount of Expenses incurred by each WP Director Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines and amounts paid in settlement by each WP Director Indemnitee or on his or her behalf to the extent legally permitted and as required by the Articles and the Indemnification Agreements, without regard to the Fund Indemnity Rights, and (iii) irrevocably waives, relinquishes and releases the Fund Indemnitors and their insurers from any and all claims against the Fund Indemnitors or their insurers to enforce the Fund Indemnity Rights by way of subrogation, or otherwise. In furtherance and not in limitation of the foregoing, the Company agrees that in the event that any Fund Indemnitor or its insurer should advance any expenses or make any payment to a WP Director Indemnitee for matters subject to advancement or indemnification by the Company pursuant to an Indemnification Agreement, the Articles or otherwise, the Company shall promptly reimburse such Fund Indemnitor or such insurer and that such Fund Indemnitor or such insurer shall be subrogated to all of the claims or rights of such WP Director Indemnitee under the Indemnification Agreements, the Articles or otherwise including to the payment of expenses in an action to collect. The Company agrees that any Fund Indemnitor or its insurer not a party hereto shall be an express third party beneficiary of this letter agreement, able to enforce such letter agreement according to its terms. Nothing contained in the Indemnification Agreements is intended to limit the scope of this letter agreement or the rights of the Fund Indemnitors or their insurers hereunder.

Except as otherwise provided herein, this letter agreement contains the entire agreement between the parties hereto on the subject hereof, and this letter agreement may not be changed, amended, modified, or altered, except by written agreement signed by all the parties hereto. The parties hereto acknowledge that this letter agreement was drafted jointly by the parties, and its terms shall not be construed against any party.

This letter agreement may be executed and delivered (including, without limitation, by facsimile transmission) in counterparts, each of which shall be deemed an original, but all of which shall constitute the same instrument.

The parties hereto agree that this letter agreement shall be governed by and construed in accordance with the laws of the Province of British Columbia and the Federal laws of Canada applicable therein without giving effect to applicable principles of conflicts of law to the extent that the application of another jurisdiction would be required thereby.

[Signature Page Follows]

If you are in agreement with the terms set forth above, please sign this letter agreement in the space provided below and return an executed copy to the undersigned.


Very truly yours,

INDEMNIFICATION AGREEMENT

THIS AGREEMENT (“Agreement”) is made on the day of , 2010


BETWEEN:

		Protox Therapeutics Inc., a company incorporated under the laws of British Columbia and having its registered office at 2900 – 000 Xxxxxxx Xxxxxx, Xxxxxxxxx, Xxxxxxx Xxxxxxxx, X0X 0X0;

		(the “Company”)

AND:

		— [INSERT NAME OF DIRECTOR OR OFFICER] of — [INSERT ADDRESS OF DIRECTOR OR OFFICER]

		(the “Indemnitee”)

WHEREAS:

Directors, officers and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming litigation relating to, among other things, matters that traditionally would have been brought only against the Company or business enterprise itself;

Highly competent persons have become more reluctant to serve corporations as directors, officers or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against risks of claims and actions against them arising out of their service to and activities on behalf of corporations;

The board of directors of the Company (the “Board of Directors”) has determined that the increased difficulty in attracting and retaining such persons is detrimental to the best interests of the Company and its shareholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future;

It is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified;

E.	This Agreement is a supplement to and in furtherance of the Articles of the Company (the “Articles”), any resolutions adopted pursuant thereto and the indemnification provisions of the Business Corporations Act (British Columbia), and will not be deemed a

substitute therefor, nor to diminish or abrogate any rights of the Indemnitee thereunder; and

F.	In consideration of the above, the Company desires to indemnify the Indemnitee on the terms and conditions hereinafter contained.

NOW THEREFORE, IN CONSIDERATION OF the premises and mutual covenants herein contained, and in consideration of the Indemnitee’s service or continued service as a director and/or an officer of the Company or any Affiliate, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Company and the Indemnitee do hereby covenant and agree as follows.

(b)

- 2 -

(j)

“Side Letter” means that certain Fund Indemnitor Letter Agreement, dated as of the date hereof, by and among Warburg Pincus Private Equity X, L.P., Warburg Pincus X Partners, L.P. and the Company;

ARTICLE 2: AGREEMENT TO SERVE

2.1 The Indemnitee agrees to become and serve as or continue to be and serve as, as the case may be, a director and/or an officer of the Company and, if requested by the Company and provided it is agreeable to the Indemnitee, the Indemnitee also agrees to become and serve as a director and/or an officer of any Affiliate designated by the Company.

ARTICLE 3: INDEMNIFICATION

3.1 Except as otherwise provided herein, the Company agrees to indemnify and save harmless the Indemnitees to the fullest extent authorized by the Business Corporations Act against all judgments, penalties and fines awarded or imposed in, and all amounts paid in settlement (“settlement amounts”) of, any proceeding in which any of the Indemnitees:

(a)

are or may be joined as a party, or

(b)

are or may be liable for or in respect of a judgment, penalty or fine in, or expenses related to, such proceeding,

by reason of the Indemnitee being or having been a director or an officer of the Company or an Affiliate, including a claim for contribution or indemnity or other relief by a person who is or was a director, officer or employee of the Company or an Affiliate, and all expenses actually and reasonably incurred by the Indemnitees in respect of a proceeding identified in this Section 3.1, provided that:

(c)

in relation to the subject matter of the proceeding the Indemnitee acted honestly and in good faith with a view to the best interests of the Company or the Affiliate, as applicable; and

(d)

in the case of a proceeding other than a civil proceeding, the Indemnitee had reasonable grounds for believing that his conduct in respect of which the proceeding was brought was lawful.

3.2 To the extent permitted by the Business Corporations Act, at the request of the Indemnitees, the Company will pay all expenses actually and reasonably incurred by the Indemnitees in respect of a proceeding identified in Section 3.1 as they are incurred in advance of the final disposition of that proceeding, on receipt of the following:

(a)

a written undertaking by or on behalf of the Indemnitees to repay such amount(s) if it is ultimately determined by the Court or another tribunal of competent jurisdiction that the Company is prohibited under the Business Corporations Act from paying such expenses; and

- 3 -

(b)

satisfactory evidence as to the amount of such expenses.

3.3 The written certification of any of the Indemnitees, together with a copy of a detailed receipt, or a detailed statement indicating the amount paid or to be paid by the Indemnitees, will constitute satisfactory evidence of any expenses for the purposes of Section 3.2.

3.4 The Company acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a party to avoid expense, delay, distraction, disruption and uncertainty. In the event that any proceeding to which the Indemnitee is or becomes a party is resolved in any manner other than by adverse judgment against the Indemnitee (including, without limitation, settlement of such action, claim or proceeding with or without payment of money or other consideration) it will be presumed that the Indemnitee has been successful on the merits or otherwise in such proceeding. Anyone seeking to overcome this presumption will have the burden of proof and the burden of persuasion by clear and convincing evidence. However, the Company will not be liable to indemnify the Indemnitee under this Agreement for any amounts paid in settlement of any proceeding effected without the Company’s written consent, and the Company will not settle any proceeding in any manner that would impose any penalty or limitation on, or require any payment from, the Indemnitee without the Indemnitee’s written consent. Neither the Company nor the Indemnitee will unreasonably withhold or delay its consent to any proposed settlement.

3.5 Notwithstanding any other provision herein to the contrary, the Company will not be obligated under this Agreement to indemnify the Indemnitees:

(a)

in respect of matters with respect to which the Indemnitee must not be indemnified under the Business Corporations Act, or in respect of liability that the Indemnitee may not be relieved from under the Business Corporations Act or otherwise at law, unless in any of those cases the Court has made an order authorizing the indemnification;

(b)

with respect to any proceeding initiated or brought voluntarily by the Indemnitee or in which he is joined as a plaintiff without the written agreement of the Company, except for any proceeding brought to establish or enforce a right to indemnification under this Agreement; or

(c)

for any expenses, fines, penalties, judgements or settlement amounts which have been paid to, or on behalf of, the Indemnitees under any applicable policy of insurance or any other arrangements maintained or made available by the Company or any Affiliate for the benefit of its respective directors or officers and, for greater certainty, the indemnity provided hereunder will only apply with respect to any expenses, fines, penalties, judgements or settlement amounts which the Indemnitees may suffer or incur which would not otherwise be paid or satisfied under such insurance or other arrangements maintained or made available by the Company or such Affiliate.

- 4 -

ARTICLE 4: DENIAL OF INDEMNIFICATION

4.1 If a claim for indemnification under this Agreement is not paid in full by the Company within sixty (60) days after a written claim therefor has been received by it and the applicable approval of the Court has been obtained where required, whichever is later, the Indemnitees may any time thereafter bring suit against the Company to recover the unpaid amount of the claim and, if wholly successful on the merits or otherwise or substantially successful on the merits, the Indemnitees will also be entitled to be paid all expenses of prosecuting such claim including but not limited to legal fees as between solicitor and own client on a full indemnity basis. It will be a defence to any such action that the Indemnitee has not met the standards of conduct which make it permissible under this Agreement or applicable law for the Company to indemnify the Indemnitees for the amount claimed, but the burden of proving such defence will be on the Company.

ARTICLE 5: CONDUCT OF DEFENCE

5.1 Promptly after receiving notice from any of the Indemnitees of any proceeding identified in Section 3.1, the Company may, and upon the written request of the Indemnitees will, promptly assume conduct of the defence thereof and, at the Company’s expense, retain counsel on behalf of the Indemnitees who is reasonably satisfactory to the Indemnitees, to represent the Indemnitees in respect of the proceeding. If the Company assumes conduct of the defence on behalf of the Indemnitees, the Indemnitee hereby consents to the conduct thereof and to any action taken by the Company, in good faith, in connection therewith and the Indemnitee will fully cooperate in such defence including, without limitation, providing documents, attending examinations for discovery, making affidavits, meeting with counsel, testifying and divulging to the Company all information reasonably required to defend or prosecute the proceeding.

5.2 In connection with any proceeding in respect of which the Indemnitees may be entitled to be indemnified hereunder, the Indemnitees will have the right to employ separate counsel of their choosing and to participate in the defence thereof but the fees and disbursements of such counsel will be at the expense of the Indemnitees unless:

(a)

the Indemnitees reasonably determine that there are legal defences available to the Indemnitees that are different from or in addition to those available to the Company or any Affiliate, as the case may be, or that a conflict of interest exists which makes representation by counsel chosen by the Company not advisable;

(b)

the Company has not assumed the defence of the proceeding and employed counsel therefor reasonably satisfactory to the Indemnitees within a reasonable period of time after receiving notice thereof; or

(c)

employment of such other counsel has been authorized in writing by the Company;

in which event the reasonable fees and disbursements of such counsel will be paid by the Company, subject to the terms hereof. In any such proceeding, the Company will fully

- 5 -

cooperate in the defence of the Indemnitees including, without limitation, providing documents and causing its representatives to attend examinations for discovery, make affidavits, meet with counsel and testify and divulge all information in the Company’s possession reasonably required to defend or prosecute the proceeding.

5.3 No admission of liability and no settlement of any proceeding by the Company in a manner adverse to the Indemnitees will be made without the consent of the Indemnitees, such consent not to be unreasonably withheld. No admission of liability will be made by the Indemnitees without the consent of the Company and the Company will not be liable for any settlement of any proceeding made without its consent, such consent not to be unreasonably withheld.

ARTICLE 6: COURT APPROVAL

6.1 In the event of any claim for indemnification or payment of expenses with respect to a proceeding brought against an Indemnitee by or on behalf of the Company or an Affiliate, provided that the Indemnitee has fulfilled the conditions set forth in paragraphs (c) and (d) of Section 3.1, the Company will with reasonable efforts either:

(a)

apply to the Court for an order approving the indemnification of, or payment of expenses to, the Indemnitees, or

(b)

pay the expenses of the Indemnitees for the Indemnitees’ application to Court for an order approving the indemnification of, or payment of expeneses to, the Indemnitees.

ARTICLE 7: NO PRESUMPTIONS AS TO ABSENCE OF GOOD FAITH

7.1 Termination of any proceeding by judgment, order, settlement or conviction, or upon a plea of “nolo contendere” or its equivalent, or similar or other result, will not, of itself, create any presumption for the purposes of this Agreement that the Indemnitee did not act honestly and in good faith with a view to the best interests of the Company or an Affiliate, as the case may be, or, in the case of a proceeding other than a civil proceeding, that he or she did not have reasonable grounds for believing that his conduct was lawful (unless the judgment or order of a court or another tribunal of competent jurisdiction specifically finds otherwise). Neither the failure of the Company (including its Board of Directors, independent legal counsel or its shareholders) to have made a determination that indemnification of the Indemnitee is proper in the circumstances because he has met the applicable standard of conduct, nor an actual determination by the Company (including its Board of Directors, independent legal counsel or its shareholders) that the Indemnitee has not met such applicable standard of conduct, will be a defence to any action brought by the Indemnitees against the Company to recover the amount of any indemnification claim, nor create a presumption that the Indemnitee has not met the applicable standard of conduct.

- 6 -

ARTICLE 8: RESIGNATION

8.1 Nothing in this Agreement will prevent or restrict the Indemnitee from, at any time, changing his title or position within the Company or any Affiliate or from resigning as a director or an officer of the Company or any Affiliate. The Company and any Affiliate will have no obligation under this Agreement to continue the Indemnitee as a director or an officer.

ARTICLE 9: DEATH

9.1 For greater certainty, if the Indemnitee is deceased and is or becomes entitled to indemnification under any of the provisions of this Agreement, the Company agrees to indemnify and hold harmless the Indemnitee’s estate and the Indemnitees to the same extent as it would indemnify the Director, if alive, hereunder.

ARTICLE 10: OTHER RIGHTS AND REMEDIES

10.1 The indemnification provided for in this Agreement will not derogate from, exclude or reduce any other rights or remedies, in law or in equity, to which the Indemnitees may be entitled by operation of law or under any statute, rule, regulation or ordinance or by virtue of any available insurance coverage, including, but not limited to, the following:

(a)

the Business Corporations Act;

(b)

the constating documents of the Company or an Affiliate;

(c)

any valid and lawful agreement; or

(d)

any vote of the shareholders or disinterested directors of the Company or an Affiliate,

both as to matters arising out of the capacity of the Indemnitee as a director or an officer of the Company or an Affiliate or as to matters arising out of another capacity with the Company or an Affiliate, while being a director or an officer of the Company or an Affiliate, or as to matters arising by reason of his being or having been at the request of the Company, a director, officer or employee of any other legal entity of which the Company is or was an equity owner or creditor.

10.2 To the extent that a change in the Business Corporations Act, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Articles and this Agreement, it is the intent of the parties hereto that the Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change.

ARTICLE 11: NOTICE OF PROCEEDING

11.1 The Indemnitee agrees to give written notice to the Company as soon as practicable, and in any case, within five (5) days of being served with any statement of claim, writ, notice of

- 7 -

motion, indictment or other document commencing or continuing any proceedings against the Indemnitee as a party. If the Company receives notice from any other source of any matter which the Indemnitee would otherwise be obligated hereunder to give notice of to the Company, then the Indemnitee will be relieved of his obligation hereunder to give notice to the Company, provided that the Company has not suffered any damage from the failure of the Indemnitee to give notice as herein provided. The Company will give notice of such matter to the Indemnitee as soon as reasonably practicable.

ARTICLE 12: INDEMNITEE TO CO-OPERATE

12.1 The Indemnitee agrees to provide the Company with such information and co-operation as the Company may reasonably require from time to time in respect of all matters hereunder.

ARTICLE 13: EFFECTIVE DATE

14.1 It is the intention of the parties hereto that this Agreement and the obligations of the Company will not be affected, discharged, impaired, mitigated or released by reason of any bankruptcy, insolvency, receivership or other similar proceeding of creditors of the Company and that in such event any amount owing to the Indemnitees hereunder will be treated in the same manner as the other fees or expenses of the directors and officers of the Company.

ARTICLE 15: DURATION OF AGREEMENT

15.1 All agreements and obligations of the Company contained herein will continue until six (6) years after the end of any period the Indemnitee is an officer or director of the Company or an Affiliate but will continue thereafter so long as the Indemnitee will be subject to any proceeding (or any proceeding commenced under Section 4.1) whether or not he is acting or serving in any such capacity at the time any liability or expense is incurred for which indemnification can be provided under this Agreement, notwithstanding such six (6) year period.

ARTICLE 16: INSURANCE

16.1 The Company will use its reasonable commercial efforts to obtain and maintain a policy of insurance with respect to liability relating to its directors or officers, which policy may pursuant to its terms extend to the Indemnitee in his capacity as a director or an officer of the Company. The Company will use its reasonable commercial efforts to include the Indemnitee as an insured under such policy to the extent the Company believes are reasonable in accordance with the circumstances and will provide the Indemnitee with a copy of such policy

- 8 -

upon the Indemnitee being so included as an insured. In the event the Indemnitee is not named under such policy, the Company will immediately provide written notice of such fact to the Indemnitee.

16.2 In the event that the Indemnitee is an insured under such policy and an insurable event occurs, the Indemnitee will be indemnified promptly as provided in this Agreement regardless of whether the Company has received the insurance proceeds. The Indemnitee is entitled to full indemnification as provided in this Agreement notwithstanding any deductible amounts or policy limits contained in any such insurance policy.

ARTICLE 17: SECURITY

19.1 Except as otherwise agreed between the Company, on the one hand, and the Indemnitee or another indemnitor of the Indemnitee, on the other, including pursuant to the Side Letter, in the event of any payment to or on behalf of the Indemnitee under this Agreement, the Company will be subrogated to the extent of such payment to all of the rights of recovery of the Indemnitee, who will execute all papers reasonably required and take all action reasonably necessary to secure such rights, including execution of such documents as are necessary to enable to the Company to bring suit to enforce such rights.

19.2 Except as otherwise agreed between the Company, on the one hand, and the Indemnitee or another indemnitor of the Indemnitee, on the other, including pursuant to the Side Letter, the Company will not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that the Indemnitee has otherwise actually received such payment under any Company insurance policy, Company contract, Company agreement or otherwise (except to the extent that the Indemnitee is required (by court order or otherwise) to return such payment or to surrender it to the Company).

19.3 Except as otherwise agreed between the Company, on the one hand, and the Indemnitee or another indemnitor of the Indemnitee, on the other, including pursuant to the Side Letter, the Company’s obligation to indemnify or advance expenses hereunder to the Indemnitee who is or was serving as a director or officer of an Affiliate will be reduced by any amount the

(a)

any other provisions hereof (whether or not similar), or

(b)
