(d) The Corporation shall use its best efforts to keep such Shelf Prospectus (or a replacement Shelf Prospectus) continuously effective under the Canadian Securities Laws until the earlier of (i) the date as of which all Registrable Securities held by the Xxxxxxxx Group have been sold and (ii) the date as of which each member of the Xxxxxxxx Group is permitted to sell its Registrable Securities pursuant to Rule 45-102 (or any successor rule) without restrictions thereunder (except for the restrictions on making unusual efforts to prepare the market or payment of an extraordinary commission in respect of the sale) or reliance upon any prospectus exemption under Canadian Securities Legislation in effect at such time (such period of effectiveness, the “Canadian Shelf Period”). Subject to Section 2.3(e), the Corporation shall not be deemed to have used its best efforts to keep the Shelf Prospectus effective during the Canadian Shelf Period if the

14

Corporation voluntarily takes any action or omits to take any action that would result in any Holder of the Registrable Securities covered thereby not being able to offer and sell any Registrable Securities pursuant to such Shelf Prospectus (or a replacement Shelf Prospectus) during the Canadian Shelf Period, unless such action or omission is required by applicable law or as set forth herein.

(e) If the continued use of such Shelf Registration Statement or Shelf Prospectus at any time would require the Corporation, in the good faith judgment of the Board of Directors, to disclose material information, the premature disclosure of which would materially adversely affect the Corporation or which would substantially interfere with any material transaction being considered by the Corporation, the Corporation may, upon giving at least 10 days’ prior written notice of such action to the Holders, suspend use of the Shelf Registration Statement and/or the Shelf Prospectus, as applicable, for up to 45 consecutive days (a “Shelf Suspension”); provided, however, at the expiry of such Shelf Suspension if in the good faith judgment of the Board of Directors the disclosure of the material information continues to be premature and the disclosure of which would still materially adversely affect the Corporation or substantially interfere with the proposed transaction if made, the Board of Directors may continue the Shelf Suspension for an additional 30 consecutive days; provided, further, however, that the Corporation shall not be permitted to utilize its suspension rights under this Section 2.3(e) for more than 90 days in total in any consecutive twelve month period. The Corporation shall immediately notify the Holders upon the termination of any Shelf Suspension, amend or supplement the prospectus forming a part of the Shelf Registration Statement and/or the Shelf Prospectus, if necessary, so it does not contain any untrue statement or omission and furnish to the Holders such numbers of copies of the prospectuses as so amended or supplemented as the Holders may reasonably request.

(f) If the Holders Majority or the Xxxxxxxx Group so elects, an offering pursuant to such Shelf Registration Statement and/or such Shelf Prospectus shall be in the form of a firm underwritten offering, pursuant to the terms of Section 2.9. If the managing underwriter or underwriters of such proposed underwritten offering advise in writing that, in its or their opinion, the number of securities requested to be included in such underwritten offering exceeds the Underwriter’s Maximum Number which can be sold in such offering, the number of Registrable Securities to be included in such underwritten offering shall be allocated as if such underwritten offering is an underwritten Requested Registration or Short Form Registration pursuant to Section 2.7(a) hereof.

2.4 Incidental Registrations

If the Corporation for itself or for any of its security holders (other than Holders) shall at any time or times after the date hereof determine, (i) to register under the U.S. Securities Legislation any shares of its capital stock or other securities (a “U.S. Incidental Registration”) (other than: (A) the registration of an offer, sale or other disposition of securities solely to employees of, or other Persons providing services to, the Corporation, or any direct or indirect

15

subsidiary of the Corporation pursuant to an employee or similar benefit plan; or (B) relating to a merger, acquisition or other transaction of the type described in Rule 145 under the U.S. Securities Act or a comparable or successor rule, registered on XXX Xxxx X-0 or similar or successor forms), or (ii) to file a prospectus under any Canadian Securities Legislation in order to qualify a distribution of securities in its capital stock or in a form and manner that, with the appropriate changes, would permit some or all of the Registrable Securities to be qualified for distribution to the public under such prospectus (a “Canadian Incidental Qualification”) (other than in connection with the Initial Public Offering or any acquisition, securities exchange offer, corporate reorganization, dividend reinvestment plan or stock option or other employee benefit plan), the Corporation shall notify each Holder of such determination at least 45 days prior to the filing of such registration statement or prospectus, and upon the written request of any Holder given in writing to the Corporation within 20 days after the receipt of such notice, the Corporation shall, subject to Section 2.7, use its best efforts as soon as practicable thereafter to cause any Registrable Securities specified in such Holder’s request to be included in such registration statement or prospectus to the extent such registration or qualification is permissible under the applicable Securities Laws and subject to the conditions of such applicable Securities Laws.

2.5 Expenses

Except to the extent otherwise required by law, the Corporation shall pay all documented expenses incurred by it in complying with its obligations to the Holders under this Agreement, including without limitation, the cost of preparing any registration statement or prospectus, all registration and filing fees, printing expenses, fees and disbursements of counsel and independent public accountants for the Corporation, fees and expenses (including reasonable counsel fees) incurred in connection with complying with state securities or “blue sky” laws, fees of the Financial Industry Regulatory Authority (FINRA), transfer fees of transfer agents and registrars, translation costs, costs of insurance, fees and expenses of maintaining the Shelf Registrations for the Shelf Periods, and reasonable fees and disbursements of one counsel in Canada and one counsel in the United States for the sellers of Registrable Securities, but excluding underwriting discounts and commissions and transfer taxes applicable to any sale of Registrable Securities.

2.6 Effective Registration Statement

A Requested Registration, a Short Form Registration, an Incidental Registration or Shelf Registration shall not be deemed to have been effected unless, with respect to a U.S. Registration, the registration statement relating thereto has become and remained effective with the SEC for the period required for the distribution of all Registrable Securities included thereunder or, with respect to a Canadian Qualification, a receipt (or its equivalent) for the (final) prospectus relating thereto has been issued by the applicable Canadian Commission(s). Notwithstanding the foregoing, a Requested Registration, a Short Form Registration, an Incidental Registration or a Shelf Registration will be deemed not to have been effected or receipted if: (i) within 60 days after it has become effective with the applicable Commission(s), such Requested Registration, Short Form Registration, Incidental Registration or Shelf Registration is interfered with by any stop order, cease trade order, injunction, or other order or requirement of the applicable Commission(s) or other governmental agency or any court proceeding for any reason other than a misrepresentation or omission by any Holder; or (ii) the conditions to closing specified in the purchase agreement or underwriting agreement entered into in connection with such registration are not satisfied, other than solely by reason of some act or omission by a Holder.

16

2.7 Priority in Registration

(a) If a Requested Registration or Short Form Registration is a firm underwritten registration or offering and the managing underwriters give written advice to the Corporation of an Underwriter’s Maximum Number with respect to such Requested Registration or Short Form Registration, which is less than the aggregate number (the “Proposed Included Securities”) of the Registrable Securities requested for inclusion by Holders, plus any securities of the Corporation that the Corporation wishes to include for the Corporation’s account or the account of others (“Additional Registrable Securities”), then Additional Registrable Securities shall be deducted from the Proposed Included Securities but only to the extent necessary so that the Proposed Included Securities (after such deduction) do not exceed the Underwriter’s Maximum Number; provided that if the Proposed Included Securities (determined after deduction of the Additional Registrable Securities, as aforesaid) still exceeds the Underwriter’s Maximum Number, then the Registrable Securities requested for inclusion by Holders shall be included up to the Underwriter’s Maximum Number according to the following priority:

(i) Firstly, (A) Registrable Securities held by the Preference Holders up to the Aggregate AC Value in gross proceeds to the Preference Holders less the gross proceeds to the Preference Holders received in respect of prior sales of Registrable Securities pursuant to a registration statement or prospectus or pursuant to a broker sale pursuant to Rule 144 of the U.S. Securities Act by the Preference Holders, (B) Registrable Securities held by the Xxxxxxxx Group up to $50,000,000 aggregate amount of gross proceeds to the Xxxxxxxx Group less the gross proceeds received in respect of prior sales of Registrable Securities pursuant to a registration statement or prospectus or pursuant to a broker sale pursuant to Rule 144 of the U.S. Securities Act by the Xxxxxxxx Group (the “Xxxxxxxx Priority Allocation”), and (C) Registrable Securities held by the EdgeStone Group as of the date hereof, allocated between the Preference Holders, the Xxxxxxxx Group and the EdgeStone Group in proportion as nearly as practicable to the Sharing Factor; provided, however, that once the Xxxxxxxx Group has sold the Xxxxxxxx Priority Allocation (whether pursuant to a registration under this Agreement or otherwise), Registrable Securities shall be allocated solely among the Preference Holders up to the Aggregate AC Value in gross proceeds and the EdgeStone Group as of the date hereof on a pro rata as-if-converted to Common Shares basis; and

(ii) Secondly, any other Registrable Securities held by the Holders, allocated in proportion as nearly as practicable to the respective amount of Registrable Securities requested to be included in such registration by the respective Holders.

17

(b) If an Incidental Registration is a firm underwritten registration or offering initiated by the Corporation, and the managing underwriters give written advice to the Corporation of an Underwriter’s Maximum Number with respect to such Incidental Registration, then: (i) the Corporation shall be entitled to include in such registration or offering that number of securities which the Corporation proposes to offer and sell for its own account in such registration or offering and which does not exceed the Underwriter’s Maximum Number; and (ii) the Corporation shall be obligated and required to include in such registration or offering that number of Registrable Securities which shall have been requested by Holders which does not exceed the difference between the Underwriter’s Maximum Number and that number of securities which the Corporation is entitled to include therein pursuant to clause (i) of this subsection and if it shall be necessary to cut back the number of Registrable Securities requested to be included therein by Holders, then the Registrable Securities requested to be included by Holders shall be included up to the Underwriter’s Maximum according to the following priority:

(i) Firstly, (A) Registrable Securities held by the Preference Holders up to the Aggregate AC Value in gross proceeds to the Preference Holders, less the gross proceeds to the Preference Holders received in respect of prior sales of Registrable Securities pursuant to a registration statement or prospectus or pursuant to a broker sale pursuant to Rule 144 of the U.S. Securities Act by the Preference Holders, (B) Registrable Securities held by the Xxxxxxxx Group up to the Xxxxxxxx Priority Allocation in gross proceeds to the Xxxxxxxx Group, less the gross proceeds to the Xxxxxxxx Group received in respect of prior sales of Registrable Securities pursuant to a registration statement or prospectus or pursuant to a broker sale pursuant to Rule 144 of the U.S. Securities Act by the Preference Holders, and (C) Registrable Securities held by the Edgestone Group as of the date hereof, allocated between the Preference Holders, the Xxxxxxxx Group and the EdgeStone Group in proportion as nearly as practicable to the Sharing Factor; provided, however, that once the Xxxxxxxx Group has sold the Xxxxxxxx Priority Allocation (whether pursuant to a registration under this Agreement or otherwise), Registrable Securities shall be allocated solely among the Preference Holders up to the Aggregate AC Value in gross proceeds to the Preference Holders and the EdgeStone Group on a pro-rata as-if converted to Common Shares basis; and

(ii) Secondly, any other Registrable Securities held by the Holders, allocated in proportion as nearly as practicable to the respective amount of Registrable Securities requested to be included in such registration by the respective Holders.

(c) Notwithstanding that the Corporation will not be subject to any cut back on an Incidental Registration with respect to securities to be sold for its own account, it will in good faith consider the inclusion of a secondary offering component therein and if there is an over-allotment option granted to the underwriters in connection with an Incidental Registration, the Corporation will in good faith negotiate with

18

the underwriters to allow a reasonable portion of the over-allotment option to be fulfilled by the Holders in accordance with the priority of the Holders set forth in paragraph (b) above, subject to the advice of the lead underwriter.

(d) For the avoidance of doubt, allocations in this Section 2.7 among the Preference Holders shall be allocated in proportion, as nearly as practicable to the respective amount of Registrable Securities held by the Preference Holders and requested to be included in the applicable registration by the Preference Holders.

2.8 Delay Limitation

Notwithstanding any other provision of this Agreement, the Corporation shall have the right to delay any registration of Registrable Securities requested pursuant to Sections 2.1, 2.2 or 2.4 for up to 45 consecutive days if such registration would, in the good faith judgment of the Board of Directors, substantially interfere with any material transaction being considered at the time of receipt of the request from the Holders or would require the disclosure of material information, the premature disclosure of which would materially adversely affect the Corporation, and at the expiry of such 45 consecutive day period the Board of Directors will review whether such registration would, in the good faith judgment of the Board of Directors, substantially interfere with the proposed transaction or materially adversely affect the Corporation in which case the Board of Directors may delay such registration for an additional 30 consecutive days; provided, however, that the Corporation shall not be permitted to utilize its delay rights under this Section 2.8 for more than 90 days in total in any consecutive twelve month period.

2.9 Offering Procedure Obligations

In connection with any offering of Registrable Securities pursuant to this Agreement, the Corporation shall:

(a) in the case of a U.S. Registration,

(i) cause each registration statement to become and remain effective for a period of 90 days or until the Holder or Holders have completed the distribution described in such registration statement, whichever first occurs or, in the case of an underwritten public offering, until each underwriter has completed the distribution of all securities purchased by it; provided, however, that: (1) such 90 day period shall be extended for a period of time equal to the period the Holder refrains from selling any securities included in such registration at the request of an underwriter; and (2) in the case of any registration of Registrable Securities on Form S-3, F-3 or F-10 (including, with respect to a U.S. Shelf Registration) which are intended to be offered on a continuous or delayed basis, such 90 day period shall be extended, if necessary, to keep the Registration Statement effective until all such Registrable Securities are sold, provided that Rule 415, or any successor rule under the U. S. Securities Act, permits an offering on a continuous or delayed basis (or, in the case of a U.S. Shelf Registration, for the duration of the U.S. Shelf Period), and provided further that applicable

19

rules under the U.S. Securities Act governing the obligation to file a post effective amendment permit, in lieu of filing a post effective amendment that (I) includes any prospectus required by Section 10(a)(3) of the U.S. Securities Act or (II) reflects facts or events representing a material or fundamental change in the information set forth in the registration statement, the incorporation by reference of information required to be included in (I) and (II) above contained in periodic reports filed pursuant to Section 13 or 15(d) of the U.S. Exchange Act in the registration statement;

(ii) prepare and file with the SEC such amendments and supplements to such registration statement and prospectus related thereto as may be necessary to keep such registration statement effective for the period specified in paragraph (i) above and comply with the provisions of the U.S. Securities Act with respect to the disposition of all Registrable Securities covered by such registration statement in accordance with the Holders’ intended method of disposition for such period;

(iii) immediately notify each selling Holder and each underwriter under such registration statement, at any time when a prospectus relating thereto is required to be delivered under the U.S. Securities Act, of the happening of any event of which the Corporation has knowledge as a result of which the prospectus contained in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made and, at the request of any such selling Holder, prepare and furnish to such Holder a reasonable number of copies of a supplement to or amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not include 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 in light of the circumstances under which they were made;

(iv) advise each selling Holder, promptly after it shall obtain knowledge thereof, of the issuance of any stop order by the SEC or other securities authority suspending the effectiveness of such registration statement and promptly use all reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued;

(v) permit any selling Holder who, in the sole and exclusive judgment, exercised in good faith, of such Holder, might be deemed to be a controlling Person of the Corporation, to participate in good faith in the preparation of such registration statement and to require the insertion therein of material furnished to the Corporation in writing, which in the reasonable judgment of such Holder and its counsel should be included, subject to review by the Corporation and its counsel after consultation with such Holder; and

20

(vi) make available to its securities holders, as soon as reasonably practicable, any earning statement covering the period of at least twelve (12) months after the effective date of such registration statement, which earning statement shall satisfy Section 11(a) of the U.S. Securities Act and any applicable regulations thereunder, including Rule 158;

(b) in the case of a Canadian Qualification, take all necessary actions as are consistent with the requirements of Section 2.9(a) to the extent such provisions would apply in the context of a qualification and offering of the Registrable Securities under Canadian Securities Legislation;

(c) furnish to each of the Holders requesting registration or qualification such number of copies of any prospectus (including any preliminary prospectus) or registration statement and prospectus or registration statement supplement or amendment as they may reasonably request in order to effect the offering and sale of Registrable Securities to be offered and sold, but only while the Corporation shall be required under the provisions of this Agreement to cause the registration statement or prospectus to remain current; and

(d) take such action in fulfillment of its obligations under this Agreement as shall be necessary to qualify the securities covered by such registration under such blue sky or other U.S. state securities legislation or Canadian Securities Legislation for offers and sales as such Holder may reasonably request, subject to the limitations herein; provided, however, that the Corporation shall not be obligated to (i) qualify as a foreign corporation to do business under the laws of any jurisdiction in which it shall not be then qualified or to file any general consent to service of process or (ii) file a prospectus or registration statement in any jurisdiction where it has not previously filed a prospectus or registration statement.

If requested by (i) the Holders Majority in connection with an offering in accordance with Section 2.1 or 2.3 of this Agreement, (ii) the Xxxxxxxx Group in connection with an offering in accordance with Section 2.3 of this Agreement, or (iii) the Holders requesting an offering in accordance with Section 2.2 of this Agreement, (I) the Corporation and the requesting Holders shall enter into an underwriting agreement with a nationally recognized investment banking firm or firms selected by the Board of Directors and acceptable to a majority in interest of the Holders requesting the inclusion of their Registrable Securities in the offering containing representations, warranties, indemnities and agreements then customarily included by an issuer in underwriting agreements of that type; provided, however, that the liability of each Holder in respect of any indemnification, contribution or other obligation of such Holder arising under such underwriting agreement (i) shall be limited to losses arising out of or based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any prospectus, amendment or supplement or incorporated document, in reliance upon and in conformity with written information furnished to the Corporation by or on behalf of such Holder regarding such Holder expressly for inclusion therein and (ii) shall not in any event exceed an amount equal to the net proceeds to such Holder from the disposition of the Registrable Securities disposed of by such Holder pursuant to such underwritten offering; (II) the Corporation shall, and the requesting Holders shall use commercially reasonable efforts to, cause key executives of the

21

Corporation to participate under the direction of the managing underwriter in a “road show” scheduled by such managing underwriter in such locations and of such duration as in the reasonable judgment of such managing underwriter are appropriate for such underwritten offering; and (III) the Corporation shall, and the requesting Holders shall use commercially reasonable efforts to, obtain all legal opinions, auditors consents and comfort letters and expert cooperation as may be required, including furnishing to each underwriter of Registrable Securities on the date that the registration statement with respect to such Registrable Securities becomes effective or the final prospectus with respect to such offering of Registrable Securities is receipted, (A) an opinion, dated as of such date, of counsel for the Corporation and (B) a “cold comfort” letter, dated as of such date, signed by the independent public accountants of the Corporation, in each case in form and substance as is customarily given to underwriters in an underwritten public offering.

In connection with any offering of Registrable Securities registered or qualified pursuant to this Agreement, the Corporation shall, subject to applicable law, (i) furnish each of the Holders requesting the inclusion of its Registrable Securities in such offering, at the Corporation’s expense, with unlegended certificates representing ownership of the Registrable Securities being sold, in such denominations as such Holders request; (ii) instruct the Corporation’s transfer agent and registrar to release any stop transfer orders with respect to the Registrable Securities being sold; and (iii) use its best efforts to list such Registrable Securities on each stock exchange on which the shares or other securities of the Corporation are listed.

The Corporation may require each Holder of Registrable Securities to be sold pursuant to this Agreement to furnish the Corporation with such information and undertakings as it may reasonably request regarding such Holder and the distribution of such securities as the Corporation may from time to time reasonably request in writing.

2.10 Rule 144

With a view to making available the benefits of certain rules and regulations of the SEC which may at any time permit the sale of the Registrable Securities to the public without registration, at all times after the effective date of the registration statement used in the Initial Public Offering, the Corporation agrees to:

(a) use its commercially reasonable efforts to make and keep public information available, as those terms are understood and defined in Rule l44 under the U.S. Securities Act;

(b) use its commercially reasonable efforts to file with the SEC in a timely manner all reports and other documents required of the Corporation under the U.S. Securities Act and the U. S. Exchange Act; and

(c) furnish to each Holder forthwith upon request a written statement by the Corporation as to its compliance with the reporting requirements of such Rule 144 and of the U.S. Securities Act and the U.S. Exchange Act, a copy of the most recent annual or quarterly report of the Corporation, and such other reports and documents so filed by the Corporation as such Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing such Holder to sell any Registrable Securities without registration.

22

2.11 Indemnification

(a) In the event of any registration or qualification of Registrable Securities pursuant to this Agreement, the Corporation shall hold harmless and indemnify each of the Holders and their respective officers, directors, partners, employees, members, advisors and agents and their respective affiliates and each other Person, if any, who controls any of the foregoing Persons, if any, from and against any losses (other than loss of profits), claims, damages or liabilities to which any of them may be subject under any applicable Securities Laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such Registrable Securities were registered, or any document incidental to the registration or sale of such Registrable Securities, or which arise out of or are based upon the omission or alleged omission to state therein any material fact required to be stated therein or necessary to make the statement not misleading, (ii) an untrue statement or allegedly untrue statement of a material fact in any prospectus, preliminary prospectus or any issuer free writing prospectus relating to the Registrable Securities or omission or alleged omission to state a material fact, necessary to make the statements therein in light of the circumstances under which they were made not misleading, and (iii) any violation by the Corporation of any applicable Securities Laws relating to action or inaction required by the Corporation in connection with such registration or sale under such Securities Laws; provided, however, that the Corporation will not be liable in any case to any given Holder to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any such prospectus, registration statement or document in reliance upon and in conformity with information furnished in writing to the Corporation by or on behalf of such Holder specifically for use therein. This indemnity shall be in addition to any liability the Corporation may otherwise have. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Holder or any director or officer, or controlling Person of such Holder and shall survive the transfer of such securities by such Holder.

(b) In the event of any registration or qualification of Registrable Securities pursuant to this Agreement, each of the Holders for whom such registration or qualification of Registrable Securities has been made agrees, in the same manner and to the same extent as set forth in subsection (a) of this section, to severally and not jointly (and not jointly and severally) indemnify and hold harmless the Corporation, each of the other Holders and all of their respective officers, directors, partners, employees and agents, if any, from and against any losses (other than loss of profits), claims, damages or liabilities to which any of them may be subject under any applicable Securities Laws or otherwise, insofar as such losses, claims, damages or liabilities

23

(or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact relating to information furnished in writing to the Corporation by or on behalf of such Holder specifically for use in, or any untrue statement or alleged untrue statement of any material fact contained in any prospectus or registration statement under which such Registrable Securities were distributed, or any document incidental to the registration, qualification or sale of such Registrable Securities, or which arise out of or are based upon the omission or alleged omission to state therein any material fact required to be stated therein or necessary to make the statement not misleading, if such statement or omission was made in reliance upon and in conformity with information furnished in writing to the Corporation by or on behalf of such Holder specifically for use in such registration statement or prospectus, or (ii) any violation by such Holder of any applicable Securities Laws; provided, however, that the liability of each Holder hereunder shall be limited to the proportion of any such loss, claim, damage or liability which is equal to the proportion that the public offering price of the shares sold by such Holder under such registration statement or prospectus bears to the total public offering price of all securities sold thereunder, but not in any event to exceed the net proceeds received by such Holder from the sale of Registrable Securities covered by such registration statement or prospectus.

(c) Each of the Parties entitled to indemnification pursuant to this Section (each, an “Indemnified Party”) shall, promptly after receipt of notice of the commencement of any action against such Indemnified Party in respect of which indemnity may be sought pursuant to this section, notify the indemnifying party in writing of the commencement thereof. The omission of any Indemnified Party so to notify an indemnifying party of any such action shall not relieve the indemnifying party from any liability which it may have to such Indemnified Party on account of the indemnity pursuant to this section, unless (and only to the extent that) the indemnifying party was prejudiced by such omission, and in no event shall relieve the indemnifying party from any other liability which it may have to such Indemnified Party. In case any such action shall be brought against an Indemnified Party and it shall notify an indemnifying party of the commencement thereof the indemnifying party shall be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume 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 the defense thereof the indemnifying party shall not be liable to such Indemnified Party under this section for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that if any Indemnified Party shall have reasonably concluded that there may be one or more legal or equitable defenses available to such Indemnified Party which are additional to or conflict with those available to the indemnifying party, or that such claim or litigation involves or could have an effect upon matters beyond the scope of the indemnity agreement provided hereunder, the indemnifying party shall not have the right to assume the defense of such action on behalf of such Indemnified Party (but shall have the right to participate therein with counsel of its choice) and such

24

indemnifying party shall reimburse such Indemnified Party and any Person controlling such Indemnified Party for that portion of the fees and expenses of any counsel retained by the Indemnified Party which is reasonably related to the matters covered by the indemnity agreement provided hereunder. No admission of liability shall be made by the Indemnified Party without the consent of the indemnifying party. If, after having been notified by the Indemnified Party of the commencement of any action against such Indemnified Party in respect of which indemnity may be sought, the indemnifying party fails to assume the defense of such suit on behalf of the Indemnified Party within 10 days of receiving notice thereof, the Indemnified Party shall have the right to employ counsel in respect of the defense of such suit and the fees and expenses of such counsel shall be at the expense of the indemnifying party.

(d) If the indemnification provided for in this Section 2.11 is held by a court of competent jurisdiction to be otherwise available in accordance with its terms but is, for any reason, held to be unavailable or unenforceable by an Indemnified Party with respect to any losses, claims, damages or liabilities referred to herein, then the indemnifying party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense 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 in connection with the statements or omissions that resulted in such loss, liability, claim, damage or expense, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the Indemnified Party is determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the 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 liability for contribution of each Holder hereunder shall not exceed the net proceeds received by such Holder in the offering with respect to which such liability arises from the sale of Registrable Securities covered by the applicable registration statement or prospectus.

2.12 Superior Registration or Qualification Rights

The Corporation shall not grant or agree to grant any registration or qualification or other similar rights more favorable than or on parity with, or inconsistent with, any of the rights contained herein, or any other rights that would result in a reduction of the number of Registrable Securities includable in any registration statement or prospectus filed under this Agreement, all so long as any of the registration or qualification rights under this Agreement remain in effect, unless the Corporation obtains the prior written consent of the Holders Majority, and, in the event that any of the above actions affects any Holder in a manner that is materially and adversely disproportionate from the manner in which such action affects any other Holder or group of Holders, the Corporation obtains the prior written consent of each such Holder who is disproportionately affected.

25

(b) for the purposes of any obligation of the Corporation hereunder to effect a Canadian Qualification for the benefit of such Holder, the date that all Registrable Securities held by such Holder may be sold under Rule 45-102 (or any successor rule) without restrictions thereunder (except for the restrictions on making unusual efforts to prepare the market or payment of an extraordinary commission in respect of the sale) and without a prospectus or reliance on a prospectus exemption under applicable Canadian Securities Legislation;

3.3 Changes in Registrable Securities

If and as often as, there is any change in the Registrable Securities by way of reclassification or exchange, or through a merger, amalgamation, consolidation or capital reorganization, or by any other means, appropriate adjustment shall be made in the provisions hereof so that the rights and privileges granted hereby shall continue with respect to the Registrable Securities as so changed.

3.4 Assignment

3.7 Waivers, Amendments

Except as otherwise expressly provided in this Agreement and without limiting the applicability of the following sentence, no amendment, waiver or termination of this Agreement shall be binding unless executed in writing by the party to be bound thereby. Any amendment or waiver of this Agreement or any provision hereof shall be binding on all Parties, and each party shall sign any documents amending, waiving or terminating this Agreement or a provision of this Agreement, if such document has been consented to in writing (whether signed in one or more counterparts) by the Corporation and the Holders Majority; provided, however, if the Francisco Partners Group does not hold 50% or more of the Registrable Securities (calculated on an as-if converted to Common Shares basis) held by the Preference Holders and their Permitted Transferees, consent shall be required by the Corporation and each other Holder of not less than 10% of the Registrable Securities held by the Preference Holders and their Permitted Transferees (calculated on an as-if converted to Common Shares basis and adjusted for share splits, consolidations and the like); and, provided, further, that in the event of an amendment or waiver affecting any Holder in a manner that is materially and adversely disproportionate from the manner in which such amendment or waiver affects any other Holder or group of Holders, the waiver and amendment shall require the consent in writing of each such Holder who is disproportionately affected; provided, further, however, that any amendment of this Section 3.7 shall require the consent in writing of each Holder. Except as set forth in this Agreement, no amendment or waiver of any provision of this Agreement shall constitute or be deemed to constitute a waiver of any other provision nor shall any such waiver constitute a continuing waiver.

3.8 Counterparts

This Agreement may be executed in several counterparts, each of which so executed shall be deemed to be an original and such counterparts together shall be but one and the same instrument. Each party agrees that the delivery of this Agreement by facsimile shall have the same force and effect as delivery of original signatures.

3.9 Equitable Relief

Each of the Parties acknowledges that any breach by such party of his, her, or its obligations under this Agreement would cause substantial and irreparable damage to one or more of the other Parties and that money damages would be an inadequate remedy therefor. Accordingly, each party agrees that the other Parties or any of them will be entitled to an injunction, specific performance, and/or other equitable relief to prevent the breach of such obligations.
