REGISTRATION RIGHTS

9.1Demand Registration Rights

(a)For so long as the Investor meets the 2.5% Threshold, the Investor may require the Corporation to register all or a portion of the Registrable Securities then held by the Investor and its Affiliates by filing a Registration Statement and a Prospectus and taking such other steps as may be necessary to facilitate a Distribution of all or any portion of the Registrable Securities held by the Investor or its Affiliates.

(b)Any such registration effected pursuant to this Section 9.1 is referred to herein as a "Demand Registration."

(c)Any such request shall be made by a notice in writing (a "Request") to the Corporation and shall specify the number and the class or classes of Registrable Securities to be sold (the "Designated Registrable Securities") by the Investor, the intended method of disposition, whether such offer and sale shall be made by an underwritten public offering and the jurisdiction(s) in which the filing is to be effected. The Corporation shall, subject to Applicable Securities Laws, use its commercially reasonable efforts to file within 30 days after receipt of the Request: (i) a Registration Statement in compliance with applicable U.S. Securities Laws and (ii) a Prospectus in compliance with applicable Canadian Securities Laws, in order to permit the Distribution of all of the Designated Registrable Securities of the Investor specified in a Request. The parties shall cooperate in a timely manner in connection with such Distribution and the procedures in Schedule A shall apply.

(d)The Corporation shall not be obliged to effect:

(i)more than two Demand Registrations in any twelve (12) month period; provided that for purposes of this Section 9.1, a Demand Registration pursuant to which the Designated Registrable Securities are to be sold shall not be considered as having been effected until (1) the Registration Statement has been declared effective by the SEC and (2) a receipt has been issued by the Canadian Securities Authorities for the Prospectus and has not been withdrawn or suspended; or

(ii)a Demand Registration in the event the Corporation determines in its good faith judgment, after consultation with its financial and legal advisors, that (A) either (I) the effect of the filing of a Registration Statement and Prospectus would have a material adverse effect on the Corporation because such action would materially interfere with a material acquisition, reorganization or similar material transaction involving the Corporation; or (II) there exists at the time material non-public information relating to the Corporation the disclosure of which would be materially adverse to the Corporation, and (B) that it is therefore in the best interests of the Corporation to defer the filing of a Registration Statement and Prospectus at such time, in which case the Corporation's obligations under this Section 9.1 shall be deferred for a period of not more than ninety (90) days from the date of receipt of the Request of the Investor (such 90-day period is referred to herein as a "Blackout Period"); provided, that after any initial Blackout Period, the Corporation may not invoke a subsequent Blackout Period until 12 months have elapsed from the end of any previous Blackout Period; provided, further, that the Corporation shall not register any securities for its own account or that of any other stockholder during such 90-day period other than pursuant to a Registration Statement on Form S-8 or other registration solely relating to an offering or sale to employees or directors of the Corporation pursuant to any employee stock plan or other employee benefit arrangement.

(e)In the case of an underwritten public offering of Registrable Securities initiated pursuant to this Section 9.1, the Investor shall have the right to select the managing underwriter(s) or managing agent(s) and the counsel retained which shall perform such offering.

In such event, the Investor shall be entitled, by notice in writing given to the Corporation within twenty (20) days (except in the case of a "bought deal" in which case the Investor shall have only twenty-four (24) hours) after the receipt of any such notice by the Investor, to require that the Corporation cause any or all of the Registrable Securities held by the Investor (the "Piggyback Registrable Securities") to be included in such Prospectus (such qualification being hereinafter referred to as a "Piggyback Registration"). Notwithstanding the foregoing:

-35-

(ii)the Corporation may at any time before the effective date of such Registration Statement, and without the consent of the Investor, abandon the proposed offering in which the Investor has requested to participate; and

(iii)the Investor shall have the right to withdraw its request for inclusion of its Piggyback Registrable Securities in any Registration Statement and Prospectus pursuant to this Section 9.2 without incurring any liability to the Corporation or any other Person by giving written notice to the Corporation of its request to withdraw; provided, however, that:

such request must be made in writing five (5) Business Days prior to the execution of the underwriting agreement (or such other similar agreement) with respect to such offering; and

such withdrawal shall be irrevocable and, after making such withdrawal, the Investor shall no longer have any right to include its Piggyback Registrable Securities in the offering pertaining to which such withdrawal was made.

(b)Shelf Registration

(i)The Investor shall, subject to Section 9.1(d), have the right to require the Corporation at any time and from time to time to file a Registration Statement, including a Registration Statement covering the resale of all Registrable Securities on a delayed or continuous basis, pursuant to MJDS or on Form F-3 or Registration Statement that may be available at such time (a "Shelf Registration Statement"), and if necessary pursuant to the MJDS in connection therewith, to file a Canadian Prospectus pursuant to the provisions of National Instrument 44-102 - Shelf Distributions, which, for greater certainty, shall include BC Instrument 45-503 - Exemption from Certain Prospectus Requirements for Canadian Well-known Seasoned Issuers, and take such other steps as may be necessary to register the Distribution in the United States of all or any portion of the Registrable Securities held by the Investor (a "Shelf Registration"), by giving a notice with the information required in Section 9.1(c) to the Corporation.

-36-

(ii)Upon exercise of a Shelf Registration right as set forth in Section 9.2(b)(i), the Corporation shall, and subject to Applicable Securities Laws, use its commercially reasonable efforts to file within 30 days after receipt of the Request a Shelf Registration Statement relating to such Shelf Registration and cause such Shelf Registration Statement to become effective under the U.S. Securities Act, and, as required, prepare and file a preliminary Canadian Base Shelf Prospectus (if applicable) and a final Canadian Base Shelf Prospectus relating to such Shelf Registration and secure the issuance of a receipt for such preliminary Canadian Base Shelf Prospectus (if applicable) and final Canadian Base Shelf Prospectus, and promptly thereafter take such other steps as may be necessary in order to permit the Distribution in the United States of all or any portion of the Registrable Securities of the shareholders requested to be included in such Shelf Registration.

(iii)Upon filing any Shelf Registration Statement and, if required, a Canadian Base Shelf Prospectus, the Corporation shall use its commercially reasonable efforts to keep such Shelf Registration Statement effective with the SEC and, if required such Canadian Base Shelf Prospectus effective with the applicable Canadian Securities Authorities, respectively, at all times and to re-file such Shelf Registration Statement or renew such Canadian Base Shelf Prospectus upon its expiration by filing a preliminary Canadian Base Shelf Prospectus (if applicable) and final Canadian Base Shelf Prospectus, and to cooperate in any shelf take-down, whether or not underwritten, by amending or supplementing any Shelf Registration Statement or Canadian Base Shelf Prospectus related to such Shelf Registration as may be reasonably requested by the Investor or as otherwise required, until such time as all Registrable Securities that could be sold pursuant to such Shelf Registration Statement have been sold, are no longer outstanding or otherwise cease to be "Registrable Securities".

(iv)For so long as the Investor meets the 2.5% Threshold, and at any time that a Shelf Registration Statement is effective, if the Investor delivers a notice to the Corporation stating that it intends to effect an underwritten public offering of all or part of the Registrable Securities included on the Shelf Registration Statement (a "Shelf Underwritten Offering"), then the Corporation shall file a prospectus supplement to the Shelf Registration Statement and any applicable Canadian Prospectus as may be necessary to enable such Registrable Securities to be distributed pursuant to the Shelf Underwritten Offering, which Shelf Underwritten Offering shall be deemed a "Demand Registration" for all purposes in this Agreement. Such notice shall include substantially the same information as required by Section 9.1(c) for a Request and shall be considered a "Request" for all purposes in this Agreement, to the extent the applicable as the context may require. The Investor's rights to request a Shelf Underwritten Offering under the Shelf Registration Statement with respect to the Registrable Securities held by the Investor shall be in addition to the other registration rights provided in this Article 9; provided that the Corporation shall not be obligated to effect any such Shelf Underwritten Offering for any of the reasons set forth in Section 9.1(d) for a Demand Registration, mutatis mutandis. In addition, the provisions of Section 9.1(e) shall apply to any Shelf Underwritten Offering, mutatis mutandis. The Corporation and the Investor shall cooperate in a timely manner in connection with any such Shelf Underwritten Offering and the procedures in Schedule A shall apply to such Shelf Underwritten Offering.

All Registration Expenses incident to the performance of or compliance with this Article 9 by the parties shall be borne by the Corporation other than any and all commissions payable to any underwriter for an underwritten offering or agent for an agency offering that are attributable to the Registrable Securities to be sold by the Investor pursuant to any Demand Registration or Piggyback Registration, which commissions shall be borne by the Investor.

After receipt by the Corporation of a Request, the Corporation shall not, without the prior written consent of the Investor, authorize, issue or sell any Common Shares or Equity Securities in any jurisdiction or agree to do so or publicly announce any intention to do so (except for securities issued pursuant to any legal obligations in effect on the date of the Request or pursuant to any stock option plan or equity incentive plan) until the date which is the later of (a)(i) the date on which the Registration Statement has been declared effective by the SEC and (ii) the date on which a receipt or decision document is issued for the Prospectus filed in connection with such Demand Registration, and (b) the completion of the offering contemplated by the Demand Registration; provided, however, that the Corporation further agrees to execute such agreements as may be reasonably requested by the underwriters in connection with any underwritten offering effected pursuant to this Article 9, which agreements may subject the Corporation to a longer lock-up period.

9.7Indemnification

(a)In connection with any Demand Registration, Piggyback Registration and Shelf Registration, the Corporation shall indemnify and hold harmless the Investor, each underwriter or agent involved in the Distribution of Registrable Securities thereunder, each of their respective members, directors, officers, employees and agents, and each Person, if any, who controls such Investor, underwriter or agent within the meaning of the U.S. Securities Act or the U.S. Exchange Act against any losses, claims, damages or liabilities (including reasonable counsels' fees) ("Losses"), joint or several, to which the Investor, or such underwriter or agent or controlling Person or any of their directors, officers, employees or agents may become subject, insofar as such Losses, (or actions in respect thereof) (i) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement or Prospectus, or any amendment or supplement thereof, (ii) 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 not misleading or (iii) arise out of or are based upon any violation or alleged violation by the Corporation (or any of its agents or Affiliates) of any Applicable Securities Law, and the Corporation will pay to each the Investor, underwriter, agent or controlling Person any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Losses may result, as such expenses are incurred; provided, however, that the Corporation shall not be liable in any such case if and to the extent that any such Losses arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by the Investor, such underwriter or agent or such controlling Person expressly for use in connection with such registration; provided further, however, that the indemnity agreement contained in this Section 9.7(a) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Corporation, which consent shall not be unreasonably withheld.

(b)In connection with any Demand Registration, Piggyback Registration and Shelf Registration, the Investor shall indemnify and hold harmless the Corporation, its directors, each officer who has signed the Registration Statement, and each underwriter or agent involved in the Distribution of Registrable Securities thereunder, and each Person, if any, who controls such Investor, underwriter or agent within the meaning of the U.S. Securities Act or the U.S. Exchange Act to the same extent as the indemnity referred to in clause (a) above from the Corporation to the Investor, but only to the extent that any such Losses arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by the Investor; provided, however, that the indemnity agreement contained in this Section 9.7(b) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Investor, which consent shall not be unreasonably withheld; provided further, however, that in no event shall the aggregate amounts payable by the Investor by way of indemnity or contribution under Section 9.7(b) and 9.7(d) exceed the proceeds from the offering received by the Investor (net of any commissions paid by the Investor), except in the case of fraud or willful misconduct by the Investor.

-39-

(c)Promptly after receipt by an indemnified party under this Section 9.7 of notice of the commencement of any action (including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 9.7, give the indemnifying party notice of the commencement thereof. The indemnifying party shall have the right to participate in such action and, to the extent the indemnifying party so desires, participate jointly with any other indemnifying party to which notice has been given, and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the reasonable fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such action. The failure to give notice to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Section 9.7, only to the extent that such failure materially prejudices the indemnifying party's ability to defend such action. The failure to give notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 9.7.

(d)To provide for just and equitable contribution to joint liability under the U.S. Securities Act in any case in which either: (i) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Section 9.7 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case, notwithstanding the fact that this Section 9.7 provides for indemnification in such case, or (ii) contribution under the U.S. Securities Act may be required on the part of any party hereto for which indemnification is provided under this Section 9.7, then, and in each such case, such parties will contribute to the aggregate losses, claims, damages, liabilities, or expenses to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of each of the indemnifying party and the indemnified party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or expense, as well as to reflect any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material fact, or the omission or alleged omission of 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; provided, however, that, in any such case (x) the Investor will not be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by the Investor pursuant to such Registration Statement or Prospectus, and (y) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the U.S. Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation; and provided further that in no event shall the Investor's liability pursuant to this Section 9.7(d), when combined with the amounts paid or payable by the Investor pursuant to Section 9.7(b), exceed the proceeds from the offering received by the Investor (net of any commission paid by the Investor), except in the case of willful misconduct or fraud by the Investor.

-40-

(e)Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control; provided, however, that any matter expressly provided for or addressed by the foregoing provisions that is not expressly provided for or addressed by the underwriting agreement shall be controlled by the foregoing provisions.

(f)Unless otherwise superseded by an underwriting agreement entered into in connection with the underwritten public offering, the obligations of the Corporation and the Investor under this Section 9.7 shall survive the completion of any offering of Registrable Securities in a registration under this Article 9, and otherwise shall survive the termination of this Agreement or any provision(s) of this Agreement.

9.8Sale by Affiliates

If any Registrable Securities to be sold pursuant to any Demand Registration or Piggyback Registration are owned by an Affiliate of the Investor, all references to the Investor in this Article 9 and Schedule A shall be deemed, for the purpose of such Demand Registration or Piggyback Registration, to include both the Investor and/or the Affiliates.

 -41-

9.9Rule 144 and Regulation S

The Corporation shall use commercially reasonable efforts to file the reports required to be filed by it under the U.S. Securities Act and the U.S. Exchange Act and the rules and regulations adopted by the SEC thereunder (or, if the Corporation is not required to file such reports, it will, upon the request of the Investor, make publicly available such necessary information for so long as necessary to permit sales that would otherwise be permitted by this Agreement pursuant to Rule 144 or Regulation S under the U.S. Securities Act, as such rules may be amended from time to time or any similar rule or regulation hereafter adopted by the SEC), and it will take such further action as the Investor may reasonably request, all to the extent required from time to time to enable the Investor to sell Registrable Securities without registration under the U.S. Securities Act in transactions that would otherwise be permitted by this Agreement and within the limitation of the exemptions provided by (i) Rule 144 or Regulation S under the U.S. Securities Act, as such rules may be amended from time to time, or (ii) any similar rule or regulation hereafter adopted by the SEC. Upon the reasonable request of the Investor, the Corporation will deliver to the Investor a written statement as to whether it has complied with such requirements and, if not, the specifics thereof.

10.2Changes in Capital of the Corporation or Reorganization of the Corporation

At all times after the occurrence of any event which results in a change to the Common Shares, this Agreement will forthwith be amended and modified as necessary in order that it will apply with full force and effect, with appropriate changes, to all new securities into which the Common Shares are so changed and the parties will execute and deliver a supplemental agreement giving effect to and evidencing such necessary amendments and modifications.

Concurrent with the consummation of any reorganization, spin-off, split-off, corporate rearrangement or other similar event involving the Corporation or a Subsidiary (including the Separation) (a "Reorganization"), (i) the Corporation shall, or shall cause its Subsidiary to, execute and deliver an agreement identical to this Agreement (other than changes necessary to reflect the parties and type of securities) to the Investor with respect to all securities received by the Investor in connection with such Reorganization; and (ii) Section 8.2 herein shall have no further force or effect in this Agreement and will only be effective in the identical agreement to be entered into by the Corporation's Subsidiary.

10.3Non-Circumvention

The Corporation shall not take any actions or do any things for the purpose of circumventing the rights of the Investor under Article 3, including by way of the issuance of a debt or equity interest in a Subsidiary or Affiliate for the purpose of avoiding the application of Article 3. Notwithstanding the foregoing, the Investor acknowledges and agrees that an issuance of a debt or equity interest in a Subsidiary or Affiliate of the Corporation may be undertaken for a valid business purpose and will not, in itself, be a circumvention of the Investor's rights hereunder.

10.5Amendments and Waivers

No amendment or waiver of any provision of this Agreement shall be binding on either party unless consented to in writing by such party. No waiver of any provision of this Agreement shall constitute a waiver of any other provision, nor shall any waiver of any provision of this Agreement constitute a continuing waiver unless otherwise expressly provided.

10.6Assignment

Neither party may assign any of its rights or benefits under this Agreement, or delegate any of its duties or obligations, except with the prior written consent of the other party. Notwithstanding the foregoing, the Investor may assign and transfer all of its rights, benefits, duties and obligations under this Agreement in their entirety, without the consent of the Corporation, to an Affiliate of the Investor, provided that (i) any such assignee shall, prior to any such transfer, agree to be bound by all of the covenants of the Investor contained herein and comply with the provisions of this Agreement, and shall deliver to the Corporation a duly executed undertaking to such effect in form and substance satisfactory to the Corporation, acting reasonably, and (ii) such assignment and transfer shall not release the Investor from liability for its obligations under this Agreement.

10.7Successors and Assigns

This Agreement shall inure to the benefit of and shall be binding on and enforceable by and against the parties and their respective successors and permitted assigns. In the event any Person acquires the Corporation, whether by merger, consolidation, sale of all or substantially all of the Corporation's assets or similar business combination transaction and, as a result of such transaction, the Investor receives securities of the successor or acquiring Person (or one or more of its Affiliates), the successor or acquiring Person (or its applicable Affiliates) must, as a condition to the consummation of such transaction, agree in writing to assume the Corporation's rights and obligations under Section 7.1 (as it relates to clause (d) and (e) thereto) and Article 9 of this Agreement, mutatis mutandis.

10.8No Third Party Beneficiaries

Except as provided in Section 2.4, Section 2.5 and Section 4.4 (with respect to the Investor Nominee and the Investor's appointed observer, as applicable), this Agreement is solely for the benefit of the parties and their respective successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to or will confer on any other Person any legal or equitable right, benefit, or remedy of any nature whatsoever under or by reason of this Agreement.

10.9Expenses

Except as otherwise expressly provided in this Agreement, each party shall pay for its own costs and expenses incurred in connection with the negotiation, preparation, execution and performance of this Agreement and the transactions contemplated herein, including the fees and expenses of legal counsel, financial advisors, accountants, consultants and other professional advisors.

10.11Right to Injunctive Relief

The parties agree that any breach of the terms of this Agreement by either party would result in immediate and irreparable injury and damage to the other party which could not be adequately compensated by damages. The parties therefore also agree that in the event of any such breach or any anticipated or threatened breach by the defaulting party, the other party shall be entitled to equitable relief, including by way of temporary or permanent injunction or specific performance, without having to prove damages, in addition to any other remedies (including damages) to which such other party may be entitled at law or in equity.

10.12Counterparts
