Any such requested registration shall hereinafter be referred to as a "Demand Registration" and any such registration statement filed with the SEC shall be referred to as a "Demand Registration Statement."

-4-

(b)If a Demanding Holder so elects, an offering of Registrable Securities pursuant to a Demand Registration shall be in the form of an underwritten offering. Such Demanding Holder shall have the right to select the managing underwriter or underwriters to administer the offering; provided such managing underwriter or underwriters shall be reasonably acceptable to the Company.

(c)The Company shall not be required to effect a registration pursuant to this Section 2.1: (i) after the Company has effected five (5) registrations pursuant to this Section 2.1, and each of such registrations has been declared or ordered effective and kept effective by the Company as required by Section 2.4(a) of this Agreement; (ii) with respect to a registration of Registrable Securities during the period starting with the date thirty (30) days prior to the Company's good faith estimate of the launch date of, and ending on a date ninety (90) days after the closing date of, a Company-initiated registered offering of equity securities or securities convertible into or exchangeable for equity securities; provided that the Company is actively employing in good faith commercially reasonable efforts to launch such registered offering; (iii) during any Scheduled Black-out Period; (iv) if the Company has notified the Holder that, in the good faith judgment of the Company, it would be materially detrimental to the Company or its securityholders for such registration to be effected at such time or (v) if the filing or initial effectiveness of a Demand Registration Statement at any time would require the Company to make disclosure of any event that the Board of Directors of the Company determines would not be in the best interests of the Company and its shareholders due to a pending transaction, investigation or other event, including any public disclosure of material non-public information, where such disclosure would, at that time, materially adversely affect the Company and its shareholders, in which events described above in clauses (ii), (iv) and (v), the Company shall have the right to defer such filing for a period of not more than ninety (90) days after receipt of the request of the Holder; provided that such right to delay a request shall be exercised by the Company for not more than two periods in any twelve (12) month period and not more than ninety (90) days in the aggregate in any twelve (12) month period.  

(d)Promptly upon receipt of any request for a Demand Registration pursuant to Section 2.1(a) (but in no event more than five Business Days thereafter), the Company shall deliver a written notice (a "Demand Notice") of any such registration request to all other Holders of Registrable Securities, and the Company shall include in such Demand Registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein within ten Business Days after the date that the Demand Notice has been delivered. All requests made pursuant to this Section 2.1(d) shall specify the aggregate amount of Registrable Securities to be registered and the intended method of distribution of such securities.

(e)If the managing underwriter or underwriters of a proposed underwritten offering of the Registrable Securities included in a Demand Registration advise the Board of Directors of the Company in writing that, in its or their opinion, the number of securities requested to be included in such Demand Registration exceeds the number that can be sold in such offering without being likely to have a significant adverse effect on the price, timing or distribution of the securities offered or the market for the securities offered, the securities to be included in such Demand Registration shall be allocated as follows:

-5-

(i)first, up to 100% of the Registrable Securities that the Demanding Holder proposes (or Holders propose) to include in the Demand Registration;

(ii)second, and only if all the securities referred to in clause (i) have been included, the number of Registrable Securities that, in the opinion of such managing underwriter or underwriters can be sold without having such adverse effect, with such number to be allocated pro rata among the Holders that have requested to participate in such Demand Registration based on the relative number of Registrable Securities then held by each such Holder (provided that any securities thereby allocated to a Holder that exceed such Holder's request shall be reallocated among the remaining requesting Holders in like manner);

(iii)third, and only if all the securities referred to in clause (ii) have been included, the number of securities, if any, the Company proposes to include in such registration that, in the opinion of the managing underwriter or underwriters, can be sold without having such adverse effect; and

(iv)fourth, and only if all the securities, if any, referred to in clause (iii) have been included, the number of securities proposed to be offered by security holders having registration rights existing as of the date of this Agreement that, in the opinion of the managing underwriter or underwriters, can be sold without having such adverse effect.

(g)Any registration pursuant to this Section 2.1 may be required by the Demanding Holders to be effected by means of a shelf registration statement filed with the SEC if the Company qualifies to file using either (i) Form F-3 or S-3 or (ii) any successor form or other appropriate form under the Securities Act (a "Shelf Registration Statement") relating to any or all of the Registrable Securities in accordance with the methods and distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act. The Company shall use its commercially reasonable efforts to cause any Shelf Registration Statement to remain effective, including by filing extensions of the Shelf Registration Statement so long as Holder continues to hold Registrable Securities that are registered pursuant to the Shelf Registration Statement. The Company shall use its reasonable best efforts to keep such Shelf Registration Statement continuously effective under the Securities Act in order to permit the prospectus forming a part thereof to be usable by Holders, subject to the other terms of this Section 2, until the earlier of (i) the date as of which all Registrable Securities have been sold pursuant to the Shelf Registration Statement or another registration statement filed under the Securities Act (but in no event prior to the applicable period referred to in Section 4(3) of the Securities Act and Rule 174 thereunder).

(h)If the continued use of such Shelf Registration Statement at any time would require the Company to make disclosure of any event that the Board of Directors of the Company determines would not be in the best interests of the Company and its shareholders due to a pending transaction, investigation or other event, including any public disclosure of material non-public information, where such disclosure would, at that time, materially adversely affect the Company and its shareholders, the Company may, upon giving at least ten days' prior written notice of such action to the Holders, suspend all Holders' ability to use the Shelf Registration Statement (a "Shelf Suspension"); provided that the Company shall not be permitted to exercise a Shelf Suspension for more than two periods in any twelve (12) month period and not more than

-6-

ninety (90) days in the aggregate in any twelve (12) month period. In the case of a Shelf Suspension, the Holders agree to suspend use of the applicable prospectus in connection with any sale or purchase of, or offer to sell or purchase, Registrable Securities, upon receipt of the notice referred to above. The Company shall immediately notify the Holders upon the termination of any Shelf Suspension, amend or supplement the prospectus, if necessary, so it does not contain any material untrue statement or omission and furnish to the Holders such numbers of copies of the prospectus as so amended or supplemented as the Holders may reasonably request.

2.2 Piggyback Registration.

(a)If the Company at any time proposes to file a registration statement under the Securities Act with respect to any offering of Common Shares for its own account or for the account of any other Persons (other than (i) a Demand Registration under Section 2.1, (ii) a registration on Form F-4 or S-8 or any successor form to such referenced forms or (iii) a registration of securities solely relating to an offering and sale to employees or directors of the Company pursuant to any employee stock plan or other employee benefit plan arrangement) (a "Company Public Sale"), then, as soon as practicable (but in no event less than ten (10) calendar days prior to the proposed date of filing of such registration statement), the Company shall give written notice of such proposed filing to all Holders of Registrable Securities, and such notice shall offer each Holder the opportunity to Register under such registration statement such number of Registrable Securities as each such Holder may request in writing (a "Piggyback Registration"). Subject to Section 2.2(b), the Company shall include in such registration statement all such Registrable Securities that are requested to be included therein within five (5) days after such notice is delivered; provided that if at any time after giving written notice of its intention to Register any securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to Register or to delay registration of such securities, the Company shall give written notice of such determination to each Holder and, thereupon:

(i)in the case of a determination not to Register, shall be relieved of its obligation to Register any Registrable Securities in connection with such registration (but not from its obligation to pay the Registration Expenses in connection therewith), without prejudice, however, to the rights of any Holders of Registrable Securities entitled to request that such registration be effected as a Demand Registration under Section 2.1; and

(ii) in the case of a determination to delay Registering, in the absence of a request for a Demand Registration, shall be permitted to delay Registering any Registrable Securities for the same period as the delay in Registering such other securities.

If the offering pursuant to such registration statement is to be underwritten, then each Holder making a request for a Piggyback Registration pursuant to this Section 2.2(a) must, and the Company shall make such arrangements with the managing underwriter or underwriters so that each such Holder may, subject to Section 2.2(b), participate in such underwritten offering. If the offering pursuant to such registration statement is to be on any other basis, then each Holder making a request for a Piggyback Registration pursuant to this Section 2.2(a) must, and the

-7-

Company shall make such arrangements so that each such Holder may, participate in such offering on such basis.

Each Holder of Registrable Securities shall be permitted to withdraw all or part of such Holder's Registrable Securities from a Piggyback Registration at any time prior to the effectiveness of such registration statement.

(b)If the managing underwriter or underwriters of any proposed underwritten offering of Registrable Securities included in a Piggyback Registration informs the Company and the Holders in writing that, in its or their opinion, the number of securities which such Holders and any other Persons intend to include in such offering exceeds the number that can be sold in such offering without being likely to have a significant adverse effect on the price, timing or distribution of the securities offered or the market for the securities offered, then the securities to be included in such registration shall be allocated as follows:

(i)first, up to 100% of the securities, if any, that the Company proposes to include in the offering;

(ii)second, and only if all of the securities, if any, referred to in clause (i) have been included, up to 100% of the securities proposed to be offered by security holders exercising a contractual right to demand registration;

(iii)third, and only if all of the securities referred to in clause (ii) have been included, pro rata among the Holders who have requested participation in such offering and any other holder of securities of the Company having rights of registration that are neither expressly senior nor subordinated to the Registrable Securities; and

(iv)fourth, and only if all of the Registrable Securities and other securities referred to in clause (iii) have been included in such registration, any securities eligible for inclusion in such registration other than those set forth in clauses (i) through (iii) above.

(c)No registration of Registrable Securities effected pursuant to a request under this Section 2.2 shall be deemed to have been effected pursuant to Section 2.1 or shall relieve the Company of its obligations under Section 2.1.

2.3 Expenses of Registration.

Except as specifically provided herein, all Registration Expenses incurred in connection with any registration, qualification or compliance hereunder shall be borne by the Company. All Selling Expenses incurred in connection with any registrations hereunder shall be borne by the holders of the securities so registered pro rata on the basis of the aggregate offering or sale price of the securities so registered. The Company shall not, however, be required to pay for expenses of any registration proceeding begun pursuant to Section 2.1, the request of which has been subsequently withdrawn by the requesting Holder(s) unless (a) the withdrawal is based upon (i) the occurrence of a Material Adverse Change or (ii) material adverse information concerning the Company that the Company had not publicly revealed at least forty-eight (48) hours prior to the request or that the Company had not otherwise notified the requesting Holders of at the time

-8-

of such request or (b) the Holders of a majority of Registrable Securities, as the case may be, agree to forfeit their right to one requested registration pursuant to Section 2.1, as applicable, in which event such right shall be forfeited by all Holders.

If the Demanding Holder and/or the Holders are required to pay Registration Expenses, such expenses shall be borne by the Demanding Holder or the Holders requesting such registration in proportion to the number of Shares for which registration was requested. If the Company is required to pay the Registration Expenses of a withdrawn offering pursuant to clause (a) above, then the Demanding Holders or the Holders, as the case may be, shall not forfeit their rights pursuant to Section 2.1.

2.4 Obligations of the Company.

Whenever required to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably practicable:

(b)If the indemnification provided for in Section 2.7(a) is unavailable to an Indemnitee with respect to any losses, claims, damages, actions, liabilities, costs or expenses referred to therein or is insufficient to hold the Indemnitee harmless as contemplated therein, then the Company, in lieu of indemnifying such Indemnitee, shall contribute to the amount paid or payable by such Indemnitee as a result of such losses, claims, damages, actions, liabilities, costs or expenses in such proportion as is appropriate to reflect the relative fault of the Indemnitee, on the one hand, and the Company, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, actions, liabilities, costs or expenses as well as any other relevant equitable considerations. The relative fault of the Company, on the one hand, and of the Indemnitee, on the other hand, shall be determined by reference to, among other factors, whether the untrue or alleged untrue statement of a material fact or omission to state a material fact relates to information supplied by the Company or by the Indemnitee and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; the Company and each Holder agree that it would not be just and equitable if contribution pursuant to this Section 2.7(b) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 2.7(b). No Indemnitee guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from the Company if the Company was not guilty of such fraudulent misrepresentation.

2.8 Assignment of Registration Rights.

The rights of the Shareholder or a Holder to registration of Registrable Securities pursuant to Article 2 of this Agreement may be assigned by the Shareholder or a Holder to a transferee or assignee of Registrable Securities to which (a) there is transferred to such transferee no less than 500,000 Shares, or Securities that may be converted into 500,000 Shares (in each case as appropriately adjusted for any stock dividends, stock splits or combinations or similar events after the date of this Agreement), or (b) such transferee is an Affiliate, subsidiary or parent company, family member or family trust or similar entity of or for the benefit of the Holder; provided, however, that (i) the transferor shall, within ten (10) days after such transfer, furnish to the Company written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned and (ii) such transferee acquired such Registrable Securities in a transaction that complied with the Subscription Agreement and shall agree to be subject to all applicable restrictions set forth in the Subscription Agreement and this Agreement.

2.9 "Market Stand-Off" Agreement; Agreement to Furnish Information.

The Shareholder and each Holder hereby agree that the Shareholder and such Holder shall not sell, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale with respect to, any Common Shares (or other securities of the Company) held by the Shareholder or Holder (other than those included in the registration) for a period (the “Restricted Period”) specified by the representatives of the underwriters of Common Shares (or other securities of the Company) not to exceed ten (10) days prior and ninety (90) days following any registered sale by the Company in which the Company gave the Shareholder an opportunity to participate; provided that all

-13-

executive officers and directors of the Company enter into similar agreements and only if such Persons remain subject thereto (and are not released from such agreement) for such period. The Demanding Shareholder and each Holder agree to execute and deliver such other agreements as may be reasonably requested by the Company or the representatives of the underwriters which are consistent with the foregoing or which are necessary to give further effect thereto. Notwithstanding the foregoing, if (1) during the last 17 days of the Restricted Period, the Company issues an earnings release or material news or a material event relating to the Company occurs or (2) prior to the expiration of the Restricted Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Restricted Period, the restrictions imposed by this Section 2.9 shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

In addition, if requested by the Company or the representative of the underwriters of Common Shares (or other securities of the Company), the Demanding Holder and each Holder shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company's securities pursuant to a registration statement filed under the Securities Act in which the Demanding Holder or such Holder participates.

2.10 Rule 144 and Exchange Act Reporting.

With a view to making available to the Shareholder and Holders the benefits of certain rules and regulations of the SEC which may permit the sale of the Registrable Securities that are Common Shares to the public without registration, the Company agrees to use its commercially reasonable efforts to:

(a)make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act or any similar or analogous rule promulgated under the Securities Act, at all times after the effective date of this Agreement;

(b)file with the SEC, in a timely manner, all reports and other documents required of the Company under the Exchange Act; and

(c)so long as any of the Shareholder or a Holder owns any Registrable Securities, furnish to the Shareholder or such Holder forthwith upon request: a written statement by the Company as to its compliance with the reporting requirements of Rule 144 under the Securities Act, and of the Exchange Act; a copy of the most recent annual or quarterly report of the Company; and such other reports and documents as the Shareholder or Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing it to sell any such Common Shares without registration.

The Company shall not hereafter enter into, and is not currently a party to, any agreement with respect to its securities that is inconsistent with the rights granted to the Holders by this Agreement.
