(n) The Company will promptly notify the Underwriters in writing with full particulars of any such actual, anticipated, contemplated, threatened or prospective change referred to in the preceding paragraph and the Company shall, to the satisfaction of the Underwriters, acting reasonably, provided the Underwriters have taken all action required by them hereunder to permit the Company to do so, file promptly and, in any event, within all applicable time limitation periods, new or amended U.S. Prospectus and Canadian Prospectus or a material change report as may be required under the applicable securities laws and shall comply with all other applicable filing and other requirements under the applicable securities laws including any requirements necessary to qualify the distribution of the Shares and shall deliver to the Underwriters as soon as practicable thereafter their reasonable requirements of conformed or commercial copies of any such new or amended prospectuses. The Company will not file any such new or amended U.S. Prospectus and Canadian Prospectus or material change report without first obtaining the written approval of the form and content thereof by the Underwriters, which approval shall not be unreasonably withheld or delayed; and

(o) The Company will in good faith discuss with the Underwriters as promptly as possible any circumstance or event which is of such a nature that there is or ought to be consideration given as to whether there may be a material change or change in a material fact or other change described in the preceding two paragraphs.

If any of the conditions specified in this Section 7 shall not have been fulfilled as and when provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Underwriters and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be terminated by RBC at, or at any time prior to, a Time of Delivery, without liability on the part of the Underwriters or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements as provided in Section 8 hereof. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

8. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses (other than loss of profits) claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act, Canadian Securities Laws or any other federal, state or provincial statutory law or regulation, at common law 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 a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in the U.S. Preliminary Prospectus, the U.S. Prospectus, the Canadian Preliminary Prospectus, the Canadian Prospectus, or in any amendment thereof or supplement thereto, or any Issuer Free Writing Prospectus or any "issuer information" filed or required to be filed pursuant to Rule 433(d) under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact (except facts relating solely to the Underwriter); or required to be stated therein or necessary to make the statements therein not misleading or (ii) any noncompliance with Section 5 of the Act; and agree to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon or in conformity with written information furnished to the Company by the Underwriter, or on behalf of any Underwriter through RBC or their counsel, specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure to so notify the indemnifying party: (i) will not relieve it from liability under paragraph (a) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses, and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if: (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded based on advice of counsel that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action, or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties. Such firm shall be designated in writing by RBC. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment.

(c) In the event that the indemnity provided in paragraph (a) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Underwriters, severally and not jointly, agree to contribute to the aggregate losses (other than loss of profits), claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company and by the Underwriters from the offering of the Shares; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Shares) be responsible for any amount in excess of the Underwriting Fee applicable to the Shares purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters, severally and not jointly, shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and of the Underwriters in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering and sale of the Shares (before deducting expenses) received by them, and benefits received by the Underwriters shall be deemed to be equal to the total Underwriting Fee. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (c), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(e) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (c).

9. Liability of the Underwriters.

(a) The obligations of the Underwriters to purchase the Treasury Shares in connection with the Offering at the Closing Time shall be several (and not joint or joint and several) and shall be as to the following percentages of the Treasury Shares to be purchased at that time:

Name of Underwriter		Liability
RBC Dominion Securities Inc.		50%
TD Securities Inc.		25%
GMP Securities L.P.		17%
Haywood Securities Inc.		8%

(b) If any of the Underwriters fails to purchase its applicable percentage of the aggregate amount of the Treasury Shares at the Closing Time, the other Underwriters shall have the right, but shall not be obligated, to purchase the Treasury Shares which would otherwise have been purchased by the Underwriter which fails to purchase. If, with respect to the Treasury Shares, the non-defaulting Underwriters elect not to exercise such rights to assume the entire obligations of the defaulting Underwriter, then the Company shall have the right to terminate its obligations hereunder without liability except in respect of its indemnity, contribution and expense obligations in respect of the non-defaulting Underwriters. Nothing in this paragraph shall oblige the Company to sell to the Underwriters less than all of the aggregate amount of the Treasury Shares or shall relieve an Underwriter in default hereunder from liability to the Company.

10. Termination. Each Underwriter is entitled to terminate its obligation to purchase the Shares by written notice to that effect given to the Company at or prior to the Closing Time if:

(a) any inquiry, action, suit, investigation or other proceeding (whether formal or informal) is instituted, announced or threatened or any order is made by any Governmental Authority in relation to the Company, or there is any change of any Laws, or interpretation or administration thereof, which, in the opinion of any of the Underwriters (or any one of them), operates to prevent or restrict the distribution of the Shares in the United States or in any of the Canadian Qualifying Jurisdictions or would prevent or restrict trading in the Shares of the Company or would reasonably be expected to have a significant adverse effect on the market price, value or marketability of the Shares;

(b) there occurs any material change, or change in a material fact any other change, event or fact contemplated by Section 4(d) which, in the reasonable opinion of that Underwriters (or any one of them), would be expected to result in the purchasers of a material number of Shares exercising their right under applicable securities laws to withdraw from or rescind their purchase thereof or sue for damages in respect thereof or which would be expected to have a significant adverse effect on the market price or value of the Shares or any of them;

(c) the state of the financial markets is such that in the reasonable opinion of that Underwriter, the Shares cannot be profitably marketed;

(d) there should develop, occur or come into effect or existence any event, action, state, condition or occurrence of national or international consequence, acts of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions or any action, law, regulation, inquiry or other occurrence of any nature which, in the opinion of such Underwriter, seriously adversely affects or may seriously adversely affect the Canadian and U.S. financial markets generally or the business, operations or affairs of the Company and its Subsidiaries, taken as a whole, or the market price or value of the Shares; or

(e) In addition to the foregoing, this Agreement shall be subject to termination in the absolute discretion of the Underwriters, by notice given to the Company prior to the Closing Date, if at any time prior to such time: (i) (x) trading in the shares of Common Stock shall have been suspended by the Commission, any of the Canadian Securities Regulatory Authorities, the TSX, or (y) the TSX shall have been suspended or limited or minimum prices shall have been established on the TSX, (ii) a banking moratorium shall have been declared either by Federal, State or Provincial authorities in the United States or Canada, or a material disruption in commercial banking or securities settlement or clearance services in the United States or Canada, or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by or involving the United States or Canada of a national emergency or war, or (iv) the enactment, publication, decree or other promulgation of any statute, regulation or rule or order of any court or other government authority affecting the business or operations of the Company or its Subsidiaries, or (v) the occurrence of any other calamity or crisis or change in financial, political or economic conditions in the United States, Canada or elsewhere, the effect of which on financial markets is such as to make it, in the sole judgment of RBC, impractical or inadvisable to proceed with the offering or delivery of the Shares as contemplated by the Prospectuses.

If this Agreement is properly terminated by any of the Underwriters pursuant to this Section 10, there will be no further liability hereunder on the part of that Underwriter or of the Company to that Underwriter, except in respect of any liability that may have arisen or may later arise under Section 6 and Section 8 of this Agreement. The right of the Underwriters or any of them to terminate their respective obligations under this Agreement or to terminate this Agreement is in addition to all other rights and remedies as they may have in respect of any default, act or failure to act of any of the Company in respect of any of the matters contemplated by this Agreement. A notice of termination given by one Underwriter under this Section 10 will not be binding upon the other Underwriters.

11. Survival of Representatives and Indemnities. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter or the Company or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Shares for a period of two years.

12. Notices. In all dealings hereunder, RBC shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by RBC on behalf of the Underwriters.

13. Successors and Assigns. This Agreement shall be binding upon, and inure solely to the benefit of, the Company and the Underwriters and, to the extent provided in Section 8 hereof, the officers and directors of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

Any affiliate of any Underwriter which is duly qualified and authorized to sell the Shares in the United States pursuant to the Registration Statement and offers and sells the Shares in the United States or any affiliate of any Underwriter that signs the Canadian Prospectus shall be deemed a third party beneficiary of the representations and warranties of the Company contained in Section 1, the covenants of the Company contained in Sections 4 and 5, the indemnification and contribution obligations of the Company contained in Section 8 and the officers' certificates, legal opinions and other documents required to be delivered to the Underwriters pursuant hereto, and each such affiliate shall have the right to enforce such provisions of this Agreement to the same extent as if it were an Underwriter.

14. Time of the Essence. Time shall be of the essence of this Agreement

15. Acknowledgements. The Company acknowledges and agrees that (a) the purchase and sale of the Shares pursuant to this Agreement is an arm's-length commercial transaction between the Company and the several Underwriters, (b) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (c) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the Offering or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement, and (d) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

16. Prior Agreements. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters with respect to the subject matter hereof other than paragraphs 15 and 19 of the executed engagement letter dated May 1, 2006, which shall remain in full force and effect.

17. Applicable Law. This Agreement shall be governed by the laws of the State of New York.

18. Waiver. The Company and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

20. Counterparts. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.
