ARTICLE II

REGISTRATION RIGHTS

Section 2.01     Shelf Registration and Qualification.

(a)     U.S. Shelf Registration. The Company shall (i), as soon as reasonably practicable following the Issue Date, prepare and file an initial registration statement under the Securities Act to permit the public resale of Registrable Securities from time to time as permitted by Rule 415 (or any similar provision adopted by the Commission then in effect) of the Securities Act (a “Registration Statement”) and (ii) use its commercially reasonable efforts to cause such initial Registration Statement to become effective no later than the earlier of (i) the date that is 60 days after the Issue Date and (ii) the fifth Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Target Effective Date”). The Company will use its commercially reasonable efforts to cause such initial Registration Statement filed pursuant to this Section 2.01(a) to be continuously effective under the Securities Act, with respect to any Holder, until the earliest to occur of the following: (A) the date on which all Registrable Securities covered by the Registration Statement have been distributed in the manner set forth and as contemplated in such Registration Statement or (B) the date on which there are no longer any Registrable Securities outstanding (such period, the “Effectiveness Period”). A Registration Statement filed pursuant to this Section 2.01(a) shall be on such appropriate registration form of the Commission as shall be selected by the Company; provided that, if the Company is then eligible, it shall file such Registration Statement on Form F-3 or Form S-3 and (ii) if such Registration Statement is on Form F-1 or Form S-1 and the Company later

5

becomes eligible to register the Registrable Securities on Form F-3 or Form S-3, the Company shall amend such Registration Statement to a Registration Statement on Form F-3 or Form S-3 or file a Registration Statement on Form F-3 or Form S-3 in substitution of such Registration Statement as initially filed. A Registration Statement when declared effective (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (and, in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which a statement is made). As soon as practicable following the date that a Registration Statement becomes effective, but in any event within three Business Days of such date, the Company shall provide the Holders with written notice of the effectiveness of a Registration Statement.

(b)     Canadian Shelf Prospectus. The Company shall as soon as reasonably practicable following the Issue Date and in any event prior to the Target Effective Date, prepare and file and use commercially reasonable efforts to obtain a receipt from the Canadian Securities Authorities (other than the Canadian Securities Authorities of the Province of Quebec) for a preliminary and final Base Shelf Prospectus to qualify the distribution of all Registrable Securities, together with the number of Common Shares reasonably expected to be sold by the Company over the period that the Base Shelf Prospectus is effective. In advance of the expiration of a Base Shelf Prospectus, provided that there are Registrable Securities outstanding, the Company shall use commercially reasonable efforts to renew such Base Shelf Prospectus by filing a preliminary and final Base Shelf Prospectus such that the Company shall at all times have an effective Base Shelf Prospectus with sufficient capacity, together with the number of Common Shares reasonably expected to be sold by the Company over the period that the Base Shelf Prospectus is effective, to qualify the distribution of all Common Shares eligible for Registration pursuant to this Agreement. For greater certainty, notwithstanding anything to the contrary in this Agreement, nothing in this Agreement shall require the Company, at any time, to qualify the distribution of Registrable Securities in the Province of Quebec.

(c)      Failure to Become Effective. If a Registration Statement required by Section 2.01(a) does not become or is not declared effective by the Target Effective Date or if a receipt from the Canadian Securities Authorities for a preliminary and final Base Shelf Prospectus to qualify the distribution of all Registrable Securities is not obtained by the Target Effective Date, then each Holder shall be entitled to a payment (with respect to each of the Holder’s Registrable Securities which are included in such Registration Statement), as liquidated damages and not as a penalty, (i) for each non-overlapping 30-day period for the first 60 days following the Target Effective Date, an amount equal to 0.125% of the Liquidated Damages Multiplier, which shall accrue at the end of each such 30-day period, and (ii) for each non-overlapping 30-day period beginning on the 61st day following the Target Effective Date, an amount equal to the amount set forth in clause (i) plus an additional 0.125% of the Liquidated Damages Multiplier for each subsequent 60 days (i.e., 0.25% for 61-120 days, 0.375% for 121-180 days, and 0.5% thereafter), which shall accrue at the end of each such 30-day period, up to a maximum amount equal to 0.5% of the Liquidated Damages Multiplier per non-overlapping 30 day period (the “Liquidated Damages”), until such time as both such Registration Statement is declared or becomes effective and a receipt from the Canadian Securities Authorities for a preliminary and final Base Shelf Prospectus to qualify the distribution of all Registrable Securities is obtained or there are no longer

6

any Registrable Securities outstanding. The Liquidated Damages shall be payable within 10 Business Days after the end of each such 30-day period in immediately available funds to the account or accounts specified by the applicable Holders. Liquidated Damages shall not be prorated for any period of less than 30 days accruing during any period for which a Holder is entitled to Liquidated Damages hereunder and shall only accrue in respect of any such 30-day period upon completion of such 30-day period.

(d)     Waiver of Liquidated Damages. If the Company is unable to cause a Registration Statement to become effective or obtain a receipt from the Canadian Securities Authorities for a preliminary and final Base Shelf Prospectus to qualify the distribution of all Registrable Securities on or before the Target Effective Date, then the Company may request a waiver of the Liquidated Damages, which may be granted by the consent of the Holders of at least a majority of the outstanding Registrable Securities that have been included on such Registration Statement and to be qualified under such Base Shelf Prospectus, in their sole discretion, and which such waiver shall apply to all the Holders of Registrable Securities included on such Registration Statement or to be so qualified under such Base Shelf Prospectus.

(e)     Delay Rights. Notwithstanding anything to the contrary contained herein, the Company may, upon written notice to any Selling Holder whose Registrable Securities are included in a Registration Statement or to be qualified under a Base Shelf Prospectus, suspend such Selling Holder’s use of any prospectus which is a part of such Registration Statement or in Canada, a Shelf Prospectus Supplement (in which event the Selling Holder shall suspend sales of the Registrable Securities pursuant to such Registration Statement or in Canada, under the Base Shelf Prospectus using a Shelf Prospectus Supplement, as applicable) if (i) the Company is pursuing an acquisition, merger, reorganization, disposition or other similar transaction and the Company determines in good faith that the Company’s ability to pursue or consummate such a transaction would be adversely affected in any material respect by the use of such Registration Statement or Shelf Prospectus Supplement by the Selling Holder, or (ii) the use of such Registration Statement or Shelf Prospectus Supplement by the Selling Holder would require the disclosure of material non-public information that the Company has a bona fide business purpose for preserving or not disclosing publicly in the good faith judgment of the Company; provided, however, that in no event shall the Selling Holders be suspended from selling Registrable Securities pursuant to such Registration Statement or in Canada, under the Base Shelf Prospectus using a Shelf Prospectus Supplement, for a period that exceeds 60 consecutive calendar days or more than 120 total calendar days in any 12-month period. Upon disclosure of such information or the termination of the condition described above, the Company shall provide prompt notice to the Selling Holders whose Registrable Securities are included in such Registration Statement or to be qualified under a Base Shelf Prospectus, and shall promptly terminate any suspension of sales it has put into effect and shall take such other actions necessary or appropriate to permit registered sales of Registrable Securities or in Canada, the qualification of Registrable Securities under the Base Shelf Prospectus, as contemplated in this Agreement.

Section 2.02     Piggyback Registration.

(a)     Participation. If at any time the Company proposes to (i) file a Registration Statement (other than a Registration Statement contemplated by Section 2.01(a)) on its own behalf relating to the sale of Common Shares or on behalf of any other Persons who have or have been

7

granted registration rights (the “Other Holders”) or qualify Common Shares for distribution by prospectus under Canadian Securities Laws (other than a Base Shelf Prospectus contemplated by Section 2.01(b)) by the Company, on its own behalf, relating to the sale of Common Shares, or on behalf of Other Holders, (ii) file a prospectus supplement relating to the sale of Common Shares by the Company or any Other Holders to an effective “automatic” registration statement, so long as the Company is a WKSI at such time or, whether or not the Company is a WKSI, so long as the Registrable Securities were previously included in the underlying shelf Registration Statement or are included on an effective Registration Statement, or in any case in which Holders may participate in such offering without the filing of a post-effective amendment, in each case of (i) and (ii), for the sale of Common Shares by the Company or Other Holders in an Underwritten Offering (including an Underwritten Offering undertaken pursuant to Section 2.03), then the Company shall give not less than four Business Days’ notice (or one Business Day in connection with any overnight or bought Underwritten Offering) (including, but not limited to, notification by electronic mail) (the “Piggyback Notice”) of such proposed Underwritten Offering to each Holder (together with its Affiliates) owning more than $20,000,000 of Common Shares (determined by multiplying the number of Registrable Securities owned by the Purchased Common Share Price) or, in the case of any of the Purchaser and its Affiliates, owning any Registrable Securities, and such Piggyback Notice shall offer such Holder the opportunity to include in such Underwritten Offering such number of Registrable Securities (the “Included Registrable Securities”) as such Holder may request in writing (a “Piggyback Registration”); provided, however, that the Company shall not be required to offer such opportunity (A) to any such Holders, other than any of the Purchaser and its Affiliates, if the Holders, together with their Affiliates, do not offer a minimum of $10,000,000 of Registrable Securities in the aggregate (determined by multiplying the number of Registrable Securities owned by the Purchased Common Share Price ), or (B) to such Holders (including, for greater certainty, the Purchaser and its Affiliates) if and to the extent that the Company has been advised by the Managing Underwriter, acting in good faith, that the inclusion of Registrable Securities for sale for the benefit of such Holders will have an adverse effect on the price, timing or distribution of the Common Shares in such Underwritten Offering, then the amount of Registrable Securities to be offered for the accounts of Holders shall be determined based on the provisions of Section 2.02(b). Each Piggyback Notice shall be provided to Holders on a Business Day pursuant to Section 3.01. If practical in the context of the contemplated offering, the Company shall use reasonable efforts to increase the length of the Piggyback Notice to provide more time for the applicable Holders to make an election to participate; provided, however, that any decision to increase the length of the Piggyback Notice for longer than two Business Days shall be in the sole discretion of the Company. Each such Holder will have four Business Days (or one Business Day in connection with any overnight or bought Underwritten Offering), or such longer period as may be specified by the Company, in its sole discretion, in the Piggyback Notice, after such Piggyback Notice has been delivered to request in writing the inclusion of Registrable Securities in the Underwritten Offering. If no request for inclusion from a Holder is received within the specified time, such Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving written notice of its intention to undertake such an Underwritten Offering and prior to the closing of such Underwritten Offering, the Company shall determine for any reason not to undertake or to delay such Underwritten Offering, the Company may, at its election, give written notice of such determination to the Selling Holders and, (1) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection

8

with such terminated Underwritten Offering, and (2) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such Underwritten Offering by giving written notice to the Company of such withdrawal at least one Business Day prior to the time of pricing of such Underwritten Offering. Any Holder may deliver written notice (a “Piggyback Opt-Out Notice”) to the Company requesting that such Holder not receive notice from the Company of any proposed Underwritten Offering; provided, however, that such Holder may later revoke any such Piggyback Opt-Out Notice in writing. Following receipt of a Piggyback Opt-Out Notice from a Holder (unless subsequently revoked), the Company shall not be required to deliver any notice to such Holder pursuant to this Section 2.02(a) and such Holder shall no longer be entitled to participate in Underwritten Offerings pursuant to this Section 2.02(a), unless such Piggyback Opt-Out Notice is revoked by such Holder.

(b)     Priority of Piggyback Registration. If the Managing Underwriter or Underwriters of any proposed Underwritten Offering, acting in good faith, advise the Company that the total amount of Registrable Securities that the Selling Holders and any Other Holders intend to include in such offering exceeds the number that can be sold in such offering without being likely to have an adverse effect on the price, timing or distribution of the Common Shares offered or the market for the Common Shares, then the Common Shares to be included in such Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter or Underwriters advise the Company can be sold without having such adverse effect, with such number to be allocated pro rata among the Selling Holders and the Other Holders who have requested such Underwritten Offering or participation in the Piggyback Registration (based, for each such Selling Holder or Other Holder, on the percentage derived by dividing (A) the number of Common Shares proposed to be sold by such Selling Holder or such Other Holder in such offering by (B) the aggregate number of Common Shares proposed to be sold by all Selling Holders and all Other Holders in the Piggyback Registration).

Section 2.03     Underwritten Offering.

(a)     Prospectus Supplement. In the event that any Holder elects to dispose of Registrable Securities under a Registration Statement or by way of prospectus under Canadian Securities Laws pursuant to an Underwritten Offering and reasonably expects gross proceeds of at least $15,000,000 from such Underwritten Offering (together with any Registrable Securities to be disposed of by a Selling Holder who has elected to participate in such Underwritten Offering pursuant to Section 2.02), the Company shall, at the request of such Selling Holder(s), enter into an underwriting agreement in a form as is customary in Underwritten Offerings of securities by the Company with the Managing Underwriter or Underwriters, which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 2.08, and shall take all such other reasonable actions as are requested by the Managing Underwriter in order to expedite or facilitate the disposition of such Registrable Securities; provided, however, that the Company shall have no obligation to facilitate or participate in, including entering into any underwriting agreement, (i) more than two Underwritten Offerings requested by the Holders and their Affiliates in the aggregate, (ii) within 90 calendar days after the completion of any previous Underwritten Offering, or (iii) during the period starting 14 calendar days prior to and ending upon the expiry

9

of any black-out periods applicable to the Company, except as may be otherwise agreed by the Company and the Managing Underwriter; provided, further, that if the Company is conducting or actively pursuing a securities offering with anticipated offering proceeds of at least $20,000,000 (other than in connection with any at-the-market offering or similar continuous offering program), then the Company may suspend such Selling Holder’s right to require the Company to conduct an Underwritten Offering on such Selling Holder’s behalf pursuant to this Section 2.03; provided, however, that the Company may only suspend such Selling Holder’s right to require the Company to conduct an Underwritten Offering pursuant to this Section 2.03 once in any six month period and in no event for a period that exceeds an aggregate of 90 days in any 365-day period. The Managing Underwriter or Underwriters for such Underwritten Offering shall be selected by the Company, with the consent of the Purchaser (such consent not to be unreasonably withheld).

(b)     General Procedures. In connection with any Underwritten Offering contemplated by Section 2.03(a), the underwriting agreement into which each Selling Holder and the Company shall enter shall contain such representations, covenants, indemnities (subject to Section 2.08) and other rights and obligations as are customary in Underwritten Offerings of securities by the Company. No Selling Holder shall be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Selling Holder’s authority to enter into such underwriting agreement and to sell, and its ownership of, the securities being registered on its behalf, its intended method of distribution and any other representation required by law. If any Selling Holder disapproves of the terms of an Underwritten Offering contemplated by this Section 2.03, such Selling Holder may elect to withdraw therefrom by notice to the Company and the Managing Underwriter; provided, however, that such withdrawal must be made at least one Business Day prior to the time of pricing of such Underwritten Offering to be effective. No such withdrawal or abandonment shall affect the Company’s obligation to pay Registration Expenses unless the Underwritten Offering was initiated at the election of such Holder and the Company is not otherwise distributing any securities in connection with such the Underwritten Offering in which case the Registration Expenses incurred to the date of such terminated Underwritten Offering shall be borne solely by such Holder.

Section 2.04     Further Obligations. In connection with its obligations under this Article II, the Company will:

(a)     promptly prepare and file with the Commission such amendments and supplements to a Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such Registration Statement;

(b)     promptly prepare and file with the Canadian Securities Authorities (other than in Quebec) such amendments to the Base Shelf Prospectus and any applicable Shelf Prospectus Supplement used in connection therewith as may be necessary to comply with the provisions of Canadian Securities Laws with respect to the disposition of all Registrable Securities covered by such Base Shelf Prospectus;

(p)    if reasonably requested by a Selling Holder, (i) incorporate in a prospectus supplement or post-effective amendment such information as such Selling Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; and (ii) make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment, including in respect of any Shelf Prospectus Supplement;

(q)    if reasonably required by the Company’s transfer agent, the Company shall promptly deliver any authorizations, certificates and directions required by the transfer agent which authorize and direct the transfer agent to transfer such Registrable Securities without legend upon sale by the Holder of such Registrable Securities under the Registration Statement or Base Shelf Prospectus; and

(r)    if any Holder could reasonably be deemed to be an “underwriter,” as defined in Section 2(a)(11) of the Securities Act, in connection with the Registration Statement and any amendment or supplement thereof (a “Holder Underwriter Registration Statement”), then the Company will reasonably cooperate with such Holder in allowing such Holder to conduct customary “underwriter’s due diligence” with respect to the Company and satisfy its obligations in respect thereof. In addition, at any Holder’s request, the Company will furnish to such Holder,

13

on the date of the effectiveness of the Holder Underwriter Registration Statement and thereafter from time to time on such dates as such Holder may reasonably request (provided that such request shall not be more frequently than on an annual basis unless such Holder is offering Registrable Securities pursuant to a Holder Underwriter Registration Statement), (i) a “comfort” letter, dated such date, from the Company’s independent certified public accountants in form and substance as has been customarily given by independent certified public accountants to underwriters in Underwritten Public Offerings of securities by the Company, addressed to such Holder, (ii) an opinion, dated as of such date, of counsel representing the Company for purposes of the Holder Underwriter Registration Statement, in form, scope and substance as has been customarily given in Underwritten Public Offerings of securities by the Company, including standard “10b-5” negative assurance for such offerings, addressed to such Holder, and (iii) a standard officer’s certificate from the chief executive officer or chief financial officer, or other officers serving such functions, of the Company addressed to the Holder, as has been customarily given by such officers in Underwritten Public Offerings of securities by the Company. The Company will also use its reasonable efforts to provide legal counsel to such Holder with an opportunity to review and comment upon any such Holder Underwriter Registration Statement, and any amendments and supplements thereto, prior to its filing with the Commission.    

Notwithstanding anything to the contrary in this Section 2.04, the Company will not name a Holder as an underwriter (as defined in Section 2(a)(11) of the Securities Act) in any Registration Statement or Holder Underwriter Registration Statement, as applicable, without such Holder’s consent. If the staff of the Commission requires the Company to name any Holder as an underwriter (as defined in Section 2(a)(11) of the Securities Act), and such Holder does not consent thereto, then such Holder’s Registrable Securities shall not be included on the applicable Registration Statement and the Company shall have no further obligations hereunder with respect to Registrable Securities held by such Holder, unless such Holder has not had an opportunity to conduct customary underwriter’s due diligence as set forth in subsection (r) of this Section 2.04 with respect to the Company at the time such Holder’s consent is sought.

Each Selling Holder, upon receipt of notice from the Company of the happening of any event of the kind described in subsection (g) of this Section 2.04, shall forthwith discontinue offers and sales of the Registrable Securities by means of a prospectus or prospectus supplement until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by subsection (g) of this Section 2.04 or until it is advised in writing by the Company that the use of the prospectus may be resumed and has received copies of any additional or supplemental filings incorporated by reference in the prospectus, and, if so directed by the Company, such Selling Holder will, or will request the Managing Underwriter or Managing Underwriters, if any, to deliver to the Company (at the Company’s expense) all copies in their possession or control, other than permanent file copies then in such Selling Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

Section 2.05    Cooperation by Holders. The Company shall have no obligation to include Registrable Securities of a Holder in a Registration Statement or a Base Shelf Prospectus or in an Underwritten Offering pursuant to Section 2.03(a) if such Holder has failed to timely furnish such information that the Company determines, after consultation with its counsel, is reasonably required in order for any registration statement or prospectus supplement, as applicable, to comply with the Securities Act or Canadian Securities Laws, as applicable.

14

Section 2.06    Restrictions on Public Sale by Holders of Registrable Securities. Each Holder of Registrable Securities participating in an Underwritten Offering included in a Registration Statement agrees to enter into a customary letter agreement with underwriters providing that such Holder will not effect any public sale or distribution of Registrable Securities during the 45 calendar day period beginning on the date of a prospectus or prospectus supplement filed with the Commission or the Canadian Securities Authorities, as applicable, with respect to the pricing of such Underwritten Offering; provided, however, that (i) the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on the Company or the officers, directors or any other Affiliate of the Company on whom a restriction is imposed, (ii) the restrictions set forth in this Section 2.06 shall not apply to any Registrable Securities that are included in such Underwritten Offering by such Holder and (iii) in the event that the restrictions set forth in this Section 2.06 are waived with respect to any participant in such Underwritten Offering, such restrictions shall be deemed to have also been waived with respect to each Holder of Registrable Securities as those that are subject to such waiver.

Section 2.07    Expenses.

(a)    Certain Definitions. “Registration Expenses” shall not include Selling Expenses but otherwise means all expenses of the Company incident to the Company’s performance under or compliance with this Agreement to effect the registration of Registrable Securities on a Registration Statement or the qualification of Registrable Securities under a Base Shelf Prospectus pursuant to Section 2.01, a Piggyback Registration pursuant to Section 2.02, or an Underwritten Offering pursuant to Section 2.03, and the disposition of such Registrable Securities, including all registration, filing, TSX and other securities exchange listing and Nasdaq fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, including fees of the Canadian Securities Authorities, fees of the Financial Industry Regulatory Authority, fees of transfer agents and registrars, all word processing, duplicating and printing expenses, and the fees and disbursements of counsel for the Company and for the applicable Holders and independent public accountants for the Company, including the expenses of any “cold comfort” letters required by or incident to such performance and compliance. “Selling Expenses” means all underwriting fees, discounts and selling commissions and transfer taxes allocable to the sale of the Registrable Securities.

(b)    Expenses. The Company will pay all reasonable Registration Expenses, as determined in good faith, in connection with a shelf Registration, a Base Shelf Prospectus, a Piggyback Registration or, subject to Section 2.03(b), an Underwritten Offering, whether or not any sale is made pursuant to such shelf Registration, a Base Shelf Prospectus, Piggyback Registration or Underwritten Offering. Each Selling Holder shall pay its pro rata share of all Selling Expenses in connection with any sale of its Registrable Securities hereunder.

Section 2.08    Indemnification.

(a)    By the Company. In the event of a registration or qualification of any Registrable Securities under the Securities Act or Canadian Securities Law, as applicable, pursuant to this Agreement, the Company will indemnify and hold harmless each Selling Holder thereunder, its directors, officers, managers, partners, employees and agents and each Person, if any, who controls

15

such Selling Holder within the meaning of the Securities Act and the Exchange Act, and its directors, officers, managers, partners, employees or agents (collectively, the “Selling Holder Indemnified Persons”), against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder Indemnified Person may become subject under the Securities Act, the Exchange Act, Canadian Securities Laws or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in light of the circumstances under which such statement is made) contained in (which, for the avoidance of doubt, includes documents incorporated by reference in) the applicable Registration Statement, other registration statement, Base Prospectus Supplement or other prospectus contemplated by this Agreement, any preliminary prospectus, prospectus supplement or final prospectus contained therein or relating thereto, or any amendment or supplement thereof, or any free writing prospectus relating thereto, or arise out of or are based upon the omission or alleged 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, in light of the circumstances under which they were made) not misleading or “misrepresentation” as defined under Canadian Securities Laws, and will reimburse each such Selling Holder Indemnified Person for any legal or other expenses reasonably incurred by them in connection with investigating, defending or resolving any such Loss or actions or proceedings; provided, however, that the Company will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission or “misrepresentation” as defined under Canadian Securities Laws so made in conformity with information furnished by such Selling Holder Indemnified Person in writing specifically for use in the applicable Registration Statement, other registration statement, Base Prospectus Supplement or other prospectus, or prospectus supplement, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder Indemnified Person, and shall survive the transfer of such securities by such Selling Holder.

(b)    By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless the Company, the Company’s directors, officers, employees and agents and each Person, who, directly or indirectly, controls the Company within the meaning of the Securities Act or of the Exchange Act to the same extent as the foregoing indemnity from the Company to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in a Registration Statement, any other registration statement, Base Prospectus Supplement or other prospectus contemplated by this Agreement, any preliminary prospectus, prospectus supplement or final prospectus contained therein, or any amendment or supplement thereto or any free writing prospectus relating thereto; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification.

(c)    Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission to so notify the indemnifying party shall not relieve it from any liability that it

16

may have to any indemnified party other than under this Section 2.08(c) except to the extent that the indemnifying party is materially prejudiced by such failure. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.08 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense or employ counsel reasonably satisfactory to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. It is understood and agreed that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for the indemnified parties, and that all such fees and expenses shall be paid or reimbursed as they are incurred. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify each indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding any other provision of this Agreement, no indemnifying party shall settle any action brought against any indemnified party with respect to which such indemnified party may be entitled to indemnification hereunder without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, includes a complete and unconditional release from liability of, and does not contain any admission of wrongdoing by, the indemnified party.

(d)    Contribution. If the indemnification provided for in this Section 2.08 is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and of the indemnified party, on the other hand, in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall any Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by

17

such 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 and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating, defending or resolving any Loss that is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

(e)    Other Indemnification. The provisions of this Section 2.08 shall be in addition to any other rights to indemnification or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise. To the extent that any of the Holders is, or would be expected to be, deemed to be an underwriter of Registrable Securities pursuant to any Commission comments or policies or any court of law or otherwise, the Company agrees that the indemnification and contribution provisions contained in this Section 2.08 shall be applicable to the benefit of such Holder in its role as deemed underwriter in addition to its capacity as a Holder.

Section 2.09    Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its commercially reasonable efforts to:

(a)    make and keep public information regarding the Company available, as those terms are understood and defined in Rule 144 under the Securities Act (or any successor or similar provision then in effect), at all times from and after the date hereof;

(b)    file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act at all times from and after the date hereof; and

(c)    so long as a Holder owns any Registrable Securities, furnish (i) to the extent accurate, forthwith upon request, a written statement of the Company that it has complied with the reporting requirements of Rule 144 under the Securities Act (or any successor or similar provision then in effect) and (ii) unless otherwise available via the Commission’s EDGAR filing system, to such Holder forthwith upon request a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration.

Section 2.10    Transfer or Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities under this Article II may be transferred or assigned by each Holder to one or more transferees or assignees of Registrable Securities or securities convertible into or exercisable for Registrable Securities except that no rights provided for in Section 2.03(a) may be transferred or assigned by any Holder to any Person acquiring less than $15,000,000 in Registrable Securities (determined by multiplying the number of Registrable

18

Securities transferred or assigned by the Purchased Common Share Price); provided, however, that (a) the Company is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee or assignee and identifying the securities with respect to which such registration rights are being transferred or assigned and (b) each such transferee or assignee assumes in writing responsibility for its portion of the obligations of such transferring Holder under this Agreement.

Section 2.11    Limitation on Subsequent Registration Rights. From and after the date hereof, the Company shall not, without the prior written consent of the Holders of a majority of the outstanding Registrable Securities and securities convertible into or exercisable for Registrable Securities, voting as a single class on an as-converted basis, enter into any agreement with any current or future holder of any securities of the Company that would allow such current or future holder to require the Company to include securities in any registration statement filed by the Company on a basis, other than pari passu with, or expressly subordinate to the piggyback rights of the Holders of Registrable Securities hereunder.

Section 3.06    Specific Performance.

The existence of this right will not preclude any such Person from pursuing any other rights and remedies at law or in equity that such Person may have.

Section 3.07    Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same agreement.

Section 3.11    Amendment. This Agreement may be amended only by means of a written amendment signed by the Company and the Holders of a majority of the outstanding Registrable Securities or securities convertible into Registrable Securities, as applicable; provided, however, that no such amendment shall adversely affect the rights of any Holder hereunder without the consent of such Holder. Any amendment, supplement or modification of or to any provision of this Agreement, any waiver of any provision of this Agreement, and any consent to any departure by the Company or any Purchaser from the terms of any provision of this Agreement shall be effective only in the specific instance and for the specific purpose for which such amendment, supplement, modification, waiver or consent has been made or given.

Section 3.12    No Presumption. This Agreement has been reviewed and negotiated by sophisticated parties with access to legal counsel and shall not be construed against the drafter.

22

agent, general or limited partner, manager, member, shareholder or Affiliate of any of the foregoing, as such, for any obligations of such Persons or their respective permitted assignees under this Agreement or any documents or instruments delivered in connection herewith or for any claim based on, in respect of or by reason of such obligation or its creation, except, in each case, for any assignee of any Purchaser or a Selling Holder hereunder.

United States

Ladies and Gentlemen:

Reference is made to that certain share purchase agreement, dated June 25, 2021 (the “Purchase Agreement”), between Thaihot Investment Co., Ltd., (the “Seller”), Akumin Corp. (the Purchaser”) and the other parties thereto, pursuant to which the Purchaser will acquire all of the issued and outstanding shares of Thaihot Investment Company US Limited, which owns 100% of the issued and outstanding equity interests of Alliance HealthCare Services, Inc. Capitalized terms used herein but not otherwise defined shall have the meanings ascribed to such terms in the Purchase Agreement.

Seller Nominee Right

In connection with the transactions contemplated by the Purchase Agreement, Akumin Inc., the sole stockholder of the Purchaser (“Purchaser Parent”), and the Seller hereby agree that, effective as of the Closing and for so long as the Seller owns at least 50% of the Closing Share Consideration, the Seller shall have the right to nominate one (1) board member to the board of directors of Purchaser Parent (the “Purchaser Parent Board”) at any time an individual nominated by the Seller (a “Seller Nominee”) is not serving on the Purchaser Parent Board or if the term of the current Seller Nominee that is serving on the Purchaser Parent Board is set to expire; provided, that each Seller Nominee shall meet the requirements specified herein and be reasonably acceptable to the Governance Committee of Purchaser Parent (the “Governance Committee”). Purchaser Parent shall, as promptly as practicable, take all steps, execute all such documents and do all such acts and things necessary to have the Seller Nominee serve as a member of the Board of Directors of Purchaser Parent, provided such person is eligible to serve on the Board of Directors of Purchaser Parent. Without limiting the generality of the foregoing, Purchaser Parent shall: (i) cause the Seller Nominee to be included in the management slate of nominees for election to the Board of Directors of Purchaser Parent at every meeting of shareholders of Purchaser Parent called for that purpose and at every adjournment or postponement thereof; (ii) support the Seller Nominee for election and recommend to Purchaser Parent’ shareholders that the shareholders vote in favor of the Seller Nominee at every meeting of shareholders of Purchaser Parent called for that purpose and at every adjournment or postponement thereof; and (iii) cause all proxies received by Purchaser Parent to be voted in the manner specified by such proxies and if no specification is given, to vote such proxy in favor of the Seller Nominee as a director of Purchaser Parent.

Board Nominee Qualification Requirements

The parties agree that the initial Seller Nominee shall be Haichen Huang and that such nominee shall be appointed as director of Purchaser Parent as of the date hereof in accordance with and pursuant to subsection 125(3) of the Business Corporations Act (Ontario).

The Seller Nominee shall (i) be qualified to serve as a director under Purchaser Parent’s articles and by-laws and under the Business Corporations Act (Ontario); (ii) comply with all the Purchaser Parent’s director qualification standards in Purchaser Parent’s Corporate Governance Guidelines and Corporate Code of Conduct, each as generally applicable to the Purchaser Parent Board members as in effect from time to time; and (iii) agree in writing to comply with his/her fiduciary duties to Purchaser Parent and its stockholders.

Subsequently, prior to the Governance Committee and the Purchaser Parent Board considering whether the Seller Nominee meets the foregoing requirements and is reasonably acceptable: (i) the Seller Nominee must complete a form of director and officer questionnaire and furnish any additional information as Purchaser Parent may reasonably request in connection with the preparation of its filings under applicable law, including the Exchange Act, and exchange requirements; and (ii) Purchaser Parent shall complete or have completed promptly (A) a customary background check with respect to the Seller Nominee and (B) any other reasonable and bona fide procedures that are typically required for director nominees (e.g., interviews); provided, that such procedures do not unreasonably delay the effectiveness of such nomination. If the Governance Committee or the Purchaser Parent Board determines in good faith, that Seller Nominee does not meet the requirements specified herein, Purchaser Parent shall promptly notify Seller of the occurrence of such event and permit the Seller to provide an alternate Seller Nominee sufficiently in advance of the applicable election of directors of Purchaser Parent.

Seller Observer Right

At any time that the Seller owns at least 50% of the Closing Share Consideration and a Seller Nominee is not serving on the Purchaser Parent Board, the Seller shall have the right to appoint to the Purchaser Parent Board an observer reasonably acceptable to the Governance Committee of Purchaser Parent (the “Board Observer”) who shall have the right to attend and participate in all meetings of the Purchaser Parent Board and any committees or sub-committees of the Purchaser Parent Board in a non-voting capacity, provided that (i) if the Board Observer does not, upon the request of Purchaser Parent, before attending any meetings of the Board, execute and deliver to Purchaser Parent a confidentiality agreement reasonably acceptable to Purchaser Parent, the Board Observer may be excluded from access to any material or meeting or portion thereof if the Board determines in good faith that such exclusion is reasonably necessary to protect confidential proprietary information of Purchaser Parent or confidential proprietary information of third parties that Purchaser Parent is required to hold in confidence, or for other similar reasons; (ii) the Board Observer may be excluded from access to any material or meeting or portion thereof if the Purchaser Parent Board determines in good faith, based upon the written advice of counsel, that such exclusion is reasonably necessary to preserve the attorney-client privilege; (iii) any committee of the Purchaser Parent Board may exclude the Board Observer from attending any meeting of such committee in its discretion; and (iv) nothing herein shall prohibit the Purchaser Parent Board or any committee of the Purchaser Parent Board from taking

2

any action proposed to be taken at any meeting of the Purchaser Parent Board or committee or by written consent. The Seller agrees, and the Seller will cause any Board Observer to agree, to hold in confidence with respect to all information so provided and not use or disclose any confidential information provided to or learned by it in connection with its rights herein other than for purposes reasonably related to its interest as a shareholder of Purchaser Parent, and not to the detriment of, Purchaser Parent. The confidentiality provisions hereof will survive any termination of such rights. The Seller shall cause the Board Observer to agree to, and shall be responsible for the Board Observer’s failure to, hold in confidence and trust and to act in a fiduciary manner with respect to all information provided to such Board Observer pursuant hereto. This Letter Agreement supersedes all prior or contemporaneous written or oral agreements, understandings and negotiations with respect to the subject matter hereof.

In the event any one or more of the provisions contained in this Letter Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

Miscellaneous

Purchaser Parent shall pay the reasonable, documented out-of-pocket expenses incurred by the Seller Nominee or Board Observer in connection with his or her services provided to or on behalf of Purchaser Parent, including attending meetings (including committee meetings) or events attended on behalf of Purchaser Parent at Purchaser Parent’ request.

Purchaser Parent shall with respect to the Seller Nominee (i) purchase directors’ and officers’ liability insurance in an amount determined by the Purchaser Parent Board to be reasonable and customary and (ii) maintain such coverage for so long as a Seller Nominee nominated pursuant to the terms of this letter agreement serves as a member of the Board.

For so long as any Seller Nominee serves as a member of the Board, Purchaser Parent shall not amend, alter or repeal any right to indemnification or exculpation covering or benefiting any Seller Nominee nominated pursuant to this Agreement as and to the extent consistent with applicable law, including but not limited to any provisions of Purchaser Parent’ constituting documents (except to the extent such amendment or alteration permits Purchaser Parent to provide broader indemnification or exculpation rights on a retroactive basis than permitted prior thereto).

This Letter Agreement and any claim, controversy or dispute arising under or related to this Letter Agreement shall be governed by, and construed in accordance with the laws of, the Province of Ontario without regard to its choice of law provisions.

This Letter Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument.

No amendment or waiver of any provision of this Letter Agreement, nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto. The failure of any party to enforce any of the provisions of this Letter Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Letter Agreement in accordance with its terms. No party may assign this Letter Agreement or any of its rights or obligations hereunder and any assignment hereof will be null and void. Except as explicitly set forth herein, nothing contained in this Letter Agreement shall confer or is intended to confer on any third party or entity that is not a party to this Letter Agreement any rights under this Letter Agreement.

Agreement

Section 1.     Board Observer and Purchaser Designated Director.    

(a) Upon the terms and subject to the conditions of this Agreement, beginning on the date of this Agreement and ending on the date that the Purchaser and its Affiliates (collectively, the “Purchaser Group Members”) no longer own Notes in a principal amount equal to at least $100,000,000 (the “Board Rights Termination Date” and, the period between the date hereof and the Board Rights Termination Date, the “Board Rights Period”), the Purchaser shall have the following rights: (i) effective immediately upon approval by the Majority Disinterested Shareholders of the expansion of the size of the Board at the Special Meeting, to designate one person to be appointed to a newly-created vacancy, (ii) to designate one person to be nominated and recommended by the Board for election to the Board (A) in any management information circular or proxy statement prepared by management in connection with soliciting proxies for a meeting of the shareholders of the Company called with respect to the election of directors, and any adjournment or postponement thereof, or (B) in any action or approval by written resolution of the shareholders of the Company or the Board with respect to the election of members of the Board (any member of the Board designated in accordance with clause (i) or (ii), including any successor, the “Purchaser Designated Director”) and (iii) at any time prior to the Board Rights Termination Date when a Purchaser Designated Director is not, for any reason, serving on (or eligible to serve on) the Board, to designate one person to be appointed as a board observer (the “Board Observer”), provided, that any Purchaser Designated Director and Board Observer shall meet the requirements specified herein.

(b) Any Purchaser Designated Director shall (i) be qualified to serve as a director under the Company’s articles and by-laws and under the Business Corporations Act (Ontario); (ii) comply with all policies, procedures, processes, codes, rules, standards and guidelines of the Company, including the Company’s director qualification standards in the Company’s Corporate Governance Guidelines and Corporate Code of Conduct, each as generally applicable to Board members as in effect from time to time; and (iii) not be prohibited from serving as a director pursuant to any rule or regulation of the Commission, the Canadian Securities Commissions or any National Securities Exchange on which the common shares of the Company are then listed or admitted to trading.

(c) Prior to the Governance Committee of the Company and the Board considering whether the Purchaser Designated Director meets the foregoing requirements: (i) the Purchaser agrees to cause each Purchaser Designated Director to complete a customary form of director and officer questionnaire and furnish any additional information as the Company may reasonably require of Board members generally and such other information as the Company may reasonably request in connection with the preparation of its filings under applicable law, including the Exchange Act; and (ii) the Company shall complete or have completed promptly a customary background check with respect to the Purchaser Designated Director; provided, that such procedures do not unreasonably delay the effectiveness of such nomination. If the Governance Committee or the Board determines in good faith, that the Purchaser Designated Director does not meet the requirements specified herein, the Company shall promptly notify the Purchaser of the occurrence of such event and permit the Purchaser to provide an alternate Purchaser Designated Director sufficiently in advance of the applicable election of directors of the Company.

2

(d) The Purchaser shall exercise these rights to designate a Purchaser Designated Director or a Board Observer, from time to time, by providing written notice to the Company.

(e) If the Purchaser designates a Purchaser Designated Director and such Purchaser Designated Director is thereafter appointed or elected to the Board, then the right of the Purchaser to appoint a Board Observer shall automatically terminate for so long as the Purchaser Designated Director is serving as a member of the Board. If the Purchaser has designated a person as a Board Observer and thereafter designates a different person as a Purchaser Designated Director who becomes a member of the Board, then such person designated as a Board Observer shall cease to serve as a Board Observer.

Section 2.     Board Observation Rights.

(a)     Subject to such Board Observer previously delivering to the Company a confidentiality agreement in form of Annex A in accordance with Section 4(a), any Board Observer designated by the Purchaser hereunder shall have the right to attend and participate in all meetings (including telephonic meetings) of the full Board and any committee thereof (each, a “Committee”) during the Board Rights Period. The Board Observer shall not constitute a member of the Board and shall not be entitled to vote on, or consent to, any matters presented to the Board.

(b)     Provided such Board Observer is not excluded from a meeting or materials in accordance with Section 2(c), the Company shall (i) give the Board Observer notice of any applicable meeting or action taken by written consent at the same time and in the same manner as notice is given to the members of the Board and the members of any applicable Committee, (ii) provide the Board Observer with access to all materials and other information (including access to minutes of meetings or written consents of the full Board and any Committee) given to the members of the Board or members of any Committee, including in connection with such meetings or actions taken by written consent at the same time and in the same manner such materials and information are furnished to such members of the Board or Committee, as applicable, and (iii) provide the Board Observer with all rights to attend and participate (whether in person or by telephone or other means of electronic communication as solely determined by the Board Observer) in any such meetings as a member of the Board and any Committee.

(c)     Notwithstanding any rights to be granted or provided to the Board Observer hereunder, the Company reserves the right to exclude the Board Observer from access to any material or meeting or portion thereof if the Board reasonably determines, in good faith, that such access would prevent the members of the Board from engaging in attorney-client or solicitor-client privileged communication; provided, however, that such exclusion shall be limited to the portion of the material or meeting that is the basis for such exclusion and shall not extend to any portion of the material or meeting that does not involve or pertain to such exclusion. Notwithstanding any rights to be granted or provided to the Board Observer hereunder, the Board Observer must notify the Board of any conflicts of interest between the Board Observer or its affiliates and the Company, and if such conflict of interest is to be

3

discussed at a meeting of the Board, the Board reserves the right, in its discretion, to exclude the Board Observer from access to any material or attendance at any meeting or portion thereof and the Board Observer shall recuse himself or herself from any discussions regarding the conflict of interest. Notwithstanding any rights to be granted or provided to the Board Observer hereunder, the Company reserves the right to exclude the Board Observer from attending or participating in any in camera session or other meeting (or part of a meeting) of the Board or any Committee where only independent members of the Board may attend.

(d)     From and after the Board Rights Termination Date, the rights of the Purchaser to appoint a Purchaser Designated Director or Board Observer in Section 1(a) and the rights of any then-serving Board Observer in Sections 2(a) and Section 2(b) shall cease.

(e)     Notwithstanding anything to the contrary in this Agreement, any Board Observer in its capacity as a Board Observer shall have (i) no fiduciary duty to the Company or its shareholders and (ii) except as described in this Section 2, no obligations to the Company or its shareholders under this Agreement, except as to confidentiality in accordance with Section 4(a) and the confidentiality agreement to be entered into by the Board Observer in the form of Annex A.

Section 3.     Board Designation Rights.

(a)     The Company shall, in connection with any designation of a person to serve as a Purchaser Designated Director during the Board Rights Period, as promptly as practicable, take all necessary or advisable actions to allow the Purchaser Designated Director to serve as a member of the Board, including, to the extent applicable, (i) including the Purchaser Designated Director in the Board’s slate of nominees to the shareholders of the Company for each election of directors, (ii) including the Purchaser Designated Director in any management information circular or proxy statement prepared by management of the Company in connection with soliciting proxies for every meeting of the shareholders of the Company called with respect to the election of directors, and at every adjournment or postponement thereof, (iii) including the Purchaser Designated Director on every action or approval by written resolution of the shareholders of the Company or the Board with respect to the election of members of the Board and (iv) not nominating any candidate for the slate of nominees for each election of director in opposition to the election of the Purchaser Designated Director.

(b)     A Purchaser Designated Director may be removed or replaced by the Purchaser at any time, but not by any other Party. During the Board Rights Period, any vacancy occurring by reason of the death, disability, resignation, removal or other cessation of a person serving as a Purchaser Designated Director shall be filled by any Purchaser Designated Director designated by the Purchaser (subject to such designee meeting the standards set forth in Section 1(b)).

(c)     The Purchaser agrees, upon the Company’s request, to timely provide the Company with accurate and complete information relating to a Purchaser Designated Director as may be required to be disclosed by the Company under the Securities Act of 1933, the Securities Exchange Act of 1934 and the Canadian Securities Laws.

4

(d)     At all times while either a Purchaser Designated Director is serving as a member of the Board or a Board Observer is serving in such capacity in accordance with Section 2, such Board Observer and all of the Purchaser Group Members (as applicable) may engage in, possess an interest in, or trade in the securities of, other business ventures of any nature or description, independently or with others, similar or dissimilar to the business of the Company, and the Company, the Board and their Affiliates shall have no rights by virtue of this Agreement in and to such independent ventures or the income or profits derived therefrom, and the pursuit of any such venture, even if competitive with the business of the Company, shall not be deemed wrongful or improper; provided, however, that this Section 3(e) is subject to the conflicts of interest provisions of Section 2(c) and all applicable laws, including such restrictions prescribed by applicable securities laws in respect of insider trading and tipping in the event such Purchaser Designated Director or Board Observer becomes aware of any material non-public information during the course of its appointment. None of the Board Observer, the Purchaser or their respective Affiliates shall be obligated to present any investment opportunity to the Company even if such opportunity is of a character that the Company or any of their respective subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and each of the Board Observer, the Purchaser and their respective Affiliates shall have the right to take for such person’s own account (individually or as a partner or fiduciary) or to recommend to others any such investment opportunity. Notwithstanding the foregoing, the Board Observer shall be subject to, and comply with, the requirement to maintain confidential information pursuant to this Agreement.

(e)     The Company shall provide and maintain insurance (“D&O Insurance”), on behalf of a Purchaser Designated Director, against any liability that may be asserted against, or expense that may be incurred by, such Purchaser Designated Director in connection with the Company’s activities or such Purchaser Designated Director’s activities on behalf of the Company, on the same terms and in the same manner that such D&O Insurance is provided and maintained for the other members of the Board.

(f)     Promptly upon the designation of a Purchaser Designated Director, the Company shall enter into and maintain an indemnification agreement with such Purchaser Designated Director so as to indemnify such person and provide for the advancement of expenses therefor on the same terms and in the same manner as provided in the most recent such agreement that was entered into and maintained by the Company with a member of the Board.

(g)     The Company shall reimburse the Purchaser Designated Director or Board Observer, as applicable, for all reasonable and documented out-of-pocket expenses incurred in connection with the attendance at meetings of the Board and any Committees thereof, including travel, lodging and meal expenses, subject to any policy limitations generally applicable to Board members as in effect from time to time.

Section 4.     Miscellaneous.

(a)     Confidentiality. Each Board Observer and Purchaser Designated Director shall agree to maintain the confidentiality of all non-public information and proceedings of the Board and any Committee and to enter into, comply with, and be bound by, in all respects, the terms and conditions of a confidentiality agreement, substantially in the form attached hereto as Annex

5

A (the “Confidentiality Agreement”); provided, however, that, upon request from a Purchaser Group Member, a Board Observer or Purchaser Designated Director shall provide, on a confidential basis, such non-public information to such Purchaser Group Member; provided that such Purchaser Group Member has agreed to comply with and be bound by, in all respects, the Confidentiality Agreement. For the avoidance of doubt, the recipient of such confidential information from a Board Observer or Purchaser Designated Director may further provide such information to (i) any other Purchaser Group Member and (ii) any legal counsel, accountant or financial advisor that has been engaged by and has obligations of confidentiality to such recipient, or agrees to be bound by the provisions of the Confidentiality Agreement, to discuss such matters or information. The Purchaser agrees to indemnify the Company from any and all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever arising from the breach by a Board Observer or Purchaser Designated Director (or any recipient of such confidential information from a Board Observer or Purchaser Designated Director in accordance with this Section 4(a)) of the confidentiality obligations under the Confidentiality Agreement or this Section 4(a).

1.     As used in this Agreement, subject to Paragraph 3 below, “Confidential Information” means any and all non-public financial or other non-public information concerning the Company and its Affiliates that may hereafter be disclosed to the [Board Observer/Purchaser Designated Director] by the Company, its Affiliates or by any of their directors, officers, employees, agents, consultants, advisors or other representatives (including financial advisors, accountants or legal counsel) of the Company (the “Representatives”), including all notices, minutes, consents, materials, ideas or other information (to the extent constituting information concerning the Company and its Affiliates that is non-public financial or other non-public information) provided to the [Board Observer/Purchaser Designated Director].

2.     Except to the extent permitted by this Paragraph 2 or by Paragraph 3 or 4, the [Board Observer/Purchaser Designated Director] shall keep such Confidential Information strictly confidential, and the [Board Observer/Purchaser Designated Director] shall not use any Confidential Information made available to the [Board Observer/Purchaser Designated Director]

Annex A - 1

in his or her capacity as a member of the Board for any purpose other than management of the business and operations of the Company, or gathering information on behalf of his or her Affiliates in his or her observer capacity; provided, that the [Board Observer/Purchaser Designated Director] may, upon request from a Purchaser Group Member, share Confidential Information with such Purchaser Group Member so long as such individuals or entities agree to comply with, and be bound by, in all respects, the terms of this Agreement. For the avoidance of doubt, the recipient of such Confidential Information from the [Board Observer/Purchaser Designated Director] may further provide such Confidential Information to (i) any other Purchaser Group Member and (ii) any legal counsel, accountant or financial advisor that has been engaged by and has obligations of confidentiality to such recipient, or agrees to be bound by the provisions of this Agreement, to discuss such matters or Confidential Information. The [Board Observer/Purchaser Designated Director] may not record the proceedings of any meeting of the Board by means of an electronic recording device.

3.     The term “Confidential Information” does not include information that (i) is or becomes generally available to the public other than (a) as a result of a disclosure by the [Board Observer/Purchaser Designated Director] in violation of this Agreement or (b) in violation of a confidentiality obligation to the Company known to the [Board Observer/Purchaser Designated Director], (ii) is or becomes available to the [Board Observer/Purchaser Designated Director] on a non-confidential basis from a source not known to have an obligation of confidentiality to the Company, (iii) was already known to the [Board Observer/Purchaser Designated Director] at the time such Confidential Information was disclosed to the [Board Observer/Purchaser Designated Director], provided the [Board Observer/Purchaser Designated Director] did not become aware of such Confidential Information in violation of a confidentiality obligation to the Company known to the [Board Observer/Purchaser Designated Director] at the time of disclosure, or (iv) is independently developed by the [Board Observer/Purchaser Designated Director] without reference to any Confidential Information disclosed to the [Board Observer/Purchaser Designated Director].

4.     In the event that the [Board Observer/Purchaser Designated Director] is legally required or compelled to disclose the Confidential Information, the [Board Observer/Purchaser Designated Director] shall use reasonable efforts, to the extent permitted and practicable, to provide the Company with prompt prior written notice of such requirement so that the Company may seek, at such entities sole expense and cost, an appropriate protective order. If in the absence of a protective order, the [Board Observer/Purchaser Designated Director] is nonetheless legally required or compelled to disclose Confidential Information, the [Board Observer/Purchaser Designated Director] may disclose only the portion of the Confidential Information or other information that it is so legally required or compelled to disclose.

5.     The [Board Observer/Purchaser Designated Director] acknowledges that the Company is a public company whose common shares trade on the Toronto Stock Exchange and NASDAQ and that, under applicable securities laws, any person that may come into possession of any material information in respect of the Company or its subsidiaries, including the [Board Observer/Purchaser Designated Director], may be prohibited from buying, selling or otherwise trading in securities, or tipping, while in possession of any such information that has not been publicly disclosed.

Annex A - 2

6.     All Confidential Information disclosed by the Company or its Representatives to the [Board Observer/Purchaser Designated Director] is and will remain the property of the Company, so long as such information remains Confidential Information.

7.     It is understood and acknowledged that neither the Company nor any Representative makes any representation or warranty as to the accuracy or completeness of the Confidential Information or any component thereof.

8.     It is further understood and agreed that money damages would not be a sufficient remedy for any breach of this Agreement by the [Board Observer/Purchaser Designated Director] and that the Company shall be entitled to seek specific performance or any other appropriate form of equitable relief as a remedy for any such breach in addition to the remedies available to the Company at law.

9.     This Agreement is personal to the [Board Observer/Purchaser Designated Director], is not assignable by the [Board Observer/Purchaser Designated Director] and may be modified or waived only in writing. This Agreement is binding upon the parties hereto and their respective successors and assigns and inures to the benefit of the parties hereto and their respective successors and assigns.

10.     If any provision of this Agreement is not enforceable in whole or in part, the remaining provisions of this Agreement will not be affected thereby. No failure or delay in exercising any right, power or privilege hereunder operates as a waiver thereof, nor does any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder.

11.     THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ANY CHOICE OR CONFLICT OF LAW PROVISION (WHETHER OF THE STATE OF NEW YORK OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF NEW YORK.

12.     This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original copy of this Agreement, and all of which, when taken together, will constitute one and the same agreement.
