(the “Underwriters”), for whom Desjardins Securities Inc. is acting as representative (the “Representative”), 401,173 shares of common stock of the Company (the “Common Stock”). We further understand that the persons named in Schedule II hereto (the “Selling Shareholders”) propose to sell to the Underwriters 21,823,827 shares of Common Stock (said shares of Common Stock to be issued and sold by the Company and said shares of Common Stock to be sold by the Selling Shareholders together hereinafter called the “Underwritten Securities”). At the option of the Underwriters, the Company also proposes, subject to the terms and conditions stated herein, to grant to the Underwriters an option (the “Over-Allotment Option”) to purchase up to 2,889,250 additional shares of Common Stock to cover over-allotments (the “Option Securities”; the Option Securities, together with the Underwritten Securities, being hereinafter called the “Securities”). The Prospectus (as defined below) shall also qualify the distribution of the Option Securities.

In consideration of the agreement of the Underwriters to purchase the Securities and to offer them to the public pursuant to the Prospectus, the Company and the Selling Shareholders agree to pay to the Underwriters, at the Closing Time (as defined below), an aggregate of $1,200,150, being a fee equal to 6% of the gross proceeds from the sale of the Securities, or $0.054 per share. If the Over-Allotment Option is exercised, the Underwriters will also receive from the Company a fee of $0.054 per Option Security (collectively, the “Underwriting Fee”).

The use of the neuter in this Agreement shall include the feminine and masculine wherever appropriate. Certain terms used herein are defined in Section 18 hereof.

In the case of clause (2), the Company has included in such registration statement, as amended at the Effective Date, all information (other than Rule 430A Information) required by the Act and the rules thereunder to be included in such registration statement and the U.S. Prospectus.

(g) Neither the sale of the Securities being sold by such Selling Shareholder nor the consummation of any other of the transactions herein contemplated by such Selling Shareholder or the fulfillment of the terms hereof by such Selling Shareholder will conflict with, result in a breach or violation of, or constitute a default under any law or the charter, articles or by-laws or other governing document of such Selling Shareholder or the terms of any indenture or other agreement or instrument to which such Selling Shareholder or any of its Subsidiaries is a party or bound, or any judgment, order or decree applicable to such Selling Shareholder or any of its Subsidiaries of any Governmental Authority having jurisdiction over such Selling Shareholder or any of its Subsidiaries, except, in each case for such conflicts as would not have a material adverse effect on the financial condition or properties of the Selling Shareholder.

Said option may be exercised in whole or in part at any time on or before the 30th day after the date of the Prospectus upon written notice by the Representative to the Company setting forth the number of the Option Securities as to which the several Underwriters are exercising the Over-Allotment Option and the settlement date, which settlement date shall be a Business Day (i) no earlier than two Business Days after such notice has been given (and, in any event, no earlier than the Closing Date) and (ii) no later than ten Business Days after such notice has been given. The maximum number of Option Securities to be sold by the Company is 2,889,250. The number of Option Securities to be purchased by each Underwriter shall be the same percentage of the total number of the Option Securities to be purchased by the several Underwriters as such Underwriter is purchasing of the Underwritten Securities, subject to such adjustments as the Underwriters in their absolute discretion shall make to eliminate any fractional shares.

3 Delivery and Payment. Delivery of and payment for the Underwritten Securities and the Option Securities (if the Over-Allotment Option shall have been exercised on or before the third Business Day prior to the Closing Date) shall be made at 8:00 a.m., Toronto time, on August 19, 2005, or at such time on such later date not more than three Business Days after the foregoing date as the Representative shall designate, which date and time may be postponed by agreement among the Representative, the Company and the Selling Shareholders or as provided in Section 9 hereof (such date and time of delivery and payment for the Securities being herein called the “Closing Date” and the “Closing Time”, respectively).

Certificates for the Underwritten Securities and the Option Securities, if any, shall be delivered in accordance with the registration instructions provided by the Representative at least 48 hours prior to Closing Time.

The deliveries set forth in (i) shall also constitute the Company’s consent to the Underwriters’ use of the Canadian Final Prospectus for the Distribution of the Securities in the Canadian Qualifying Jurisdictions in compliance with the provisions of this Agreement.

(d) The Company will use its best efforts to cause the Registration Statement, if not effective at the Execution Time, and any amendment thereof, to become effective.

(e) The Company will notify the Underwriters promptly, and confirm the notice in writing, when any amendment to the Registration Statement has been filed with the Commission or has become effective, and when the Canadian Final Prospectus, or any amended Canadian Prospectus, U.S. Prospectus or any supplement thereto (collectively, “Supplementary Material”) shall have been filed, in which case the Company shall deliver to the Underwriters all signed and certified copies of such Supplementary Material in the English and French languages along with all documents similar to those referred to in Section 5(i) (b) (i), (ii), (iii) and (iv) and Section 5(i) (c) (i), (ii), (iii) and (iv) and such other documents as the Underwriters may reasonably request. Prior to the termination of the offering of the Securities and the Distribution, the Company will not file any amendment of the Registration Statement or supplement to the U.S. Prospectus or any Rule 462(b) Registration Statement or the U.S. Prospectus or any amendment to the Canadian Prospectus unless the Company has furnished to the Underwriters a copy for their review prior to filing and will not file any such proposed amendment or supplement to which the Underwriters reasonably object. Subject to the foregoing sentence, if the Registration Statement has become or becomes effective pursuant to Rule 430A, or filing of the U.S. Prospectus is otherwise required under Rule 424(b), the Company will cause the U.S. Prospectus, properly completed, and any supplement thereto to be filed in a form approved by the Representative with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence

15 reasonably satisfactory to the Representative of such timely filing. The Company will promptly advise the Representative in writing: (1) when the Registration Statement, if not effective at the Execution Time, shall have become effective, (2) when the U.S. Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed with the Commission, (3) when, prior to termination of the offering of the Securities and the Distribution, any amendment to the Registration Statement shall have been filed or become effective, (4) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the U.S. Prospectus or for any additional information, or any request by any Canadian Securities Commission that the Company make any amendment to the Canadian Preliminary Prospectus, the Canadian Final Prospectus, any Supplementary Material or that the Company provide any additional information in respect of the offering of the Securities, (5) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or of the Company obtaining knowledge of the threatening of any proceeding for that purpose or the receipt by the Company of any written communication from any Canadian Securities Commission, the TSX or any other Governmental Authority relating to the Prospectus or the Distribution of the Securities, and (6) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

(f) If, at any time when a prospectus relating to the Securities is required to be delivered under the Act, any event occurs as a result of which the Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or if it shall be necessary to amend the Registration Statement or supplement the Prospectus to comply with the applicable requirements of the Act, the Company promptly will: (1) notify the Representative of any such event, (2) prepare and file with the Commission, subject to the second sentence of paragraph (i)(d) of this Section 5, an amendment or supplement which will correct such statement or omission or effect such compliance, and (3) supply any supplemented Prospectus to the Underwriters in such quantities as the Underwriters may reasonably request.

(g) Commencing on the date hereof and until the later of: (1) the completion of the Distribution, or (2) the time at which the Act no longer requires a prospectus relating to the Securities to be delivered, the Company shall promptly notify the Underwriters in writing of:

(i) any change (actual, anticipated, contemplated, proposed or threatened, financial or otherwise) in the business, affairs, operations, assets, properties, prospects, liabilities (contingent or otherwise), capital, earnings of financial condition of the Company;

(ii) any change in any material fact (which shall include the disclosure of any previously undisclosed material fact) or any misstatement of any material fact contained in the Prospectus or any Supplementary Material;

(iii) the discovery of any new material fact that would have been required to be disclosed in the Prospectus or any Supplementary Material had it been discovered prior to the date thereof; or

16 (iv) any change in Canadian Securities Laws or the Act (in such case, the Company will notify the Selling Shareholders as well);

which is, or may be, of such a nature as to render the Prospectus or any Supplementary Material misleading or untrue in whole or in part or would result in a misrepresentation (as such term is defined under Canadian Securities Laws) therein or would result in the Registration Statement, the Prospectus or any Supplementary Material not complying with any Canadian Securities Laws or the Act or which change, misstatement or new material fact would reasonably be expected to have a significant effect on the market price or value of the Securities.

(h) During the period commencing on the date hereof and ending on the completion of the Distribution of the Securities hereunder, the Company will promptly inform the Underwriters of the full particulars of:

(ii) the issuance by the Commission, any Canadian Securities Commission, the TSX, AMEX or any other Governmental Authority of any order to cease or suspend trading of any securities of the Company or of the institution or threat of institution of any proceedings for that purpose; and

(iii) any notice or other correspondence received by any of them from any Governmental Authority requesting information, meeting or hearing or commencing or threatening any investigation into any of them or their business that would have a material adverse effect on the condition of the Company or the completion of the offering and sale of the Securities.

(i) Until the date on which the Distribution of the Securities is completed, the Company will promptly (and in any event within any applicable time limitation) comply with all legal requirements under the Act, Canadian Securities Laws, and the rules and by-laws governing the TSX and AMEX required as a result of any event described in Section 5(i)(g) or (h) in order to continue to qualify the Distribution of the Securities and the Over-Allotment Option in each of the Canadian Qualifying Jurisdictions and the offering of the Securities in the United States pursuant to this Agreement, including the prospectus amendment provisions of the Canadian Securities Laws, and will prepare and file to the satisfaction of the Underwriters any Supplementary Material which, in the opinion of the Underwriters, may be necessary or advisable. In addition to the provisions of Section 5(i)(g) or (h) above, the Company will, in good faith, discuss with the Underwriters any change, event or fact contemplated in Section 5(i)(g) or (h) which is of such a nature that there may be reasonable doubt as to whether notice should be given to the Underwriters under Section 5(i)(g) or (h) and will consult with the Underwriters with respect to the form and content of any Supplementary Material proposed to be filed by the Company, it being understood and agreed that no such Supplementary Material will be filed with the Commission or any Canadian Securities Commission prior to the review and approval by the Underwriters and their counsel. The Company shall also cooperate in all respects with the Underwriters to allow and assist the Underwriters to participate in the preparation of any Supplementary Material and to conduct all due diligence investigations which the Underwriters deem appropriate in order to fulfill their obligations as

17 underwriters and to enable the Underwriters to responsibly execute any certificate related to such Supplementary Material required to be executed by them.

(j) As soon as practicable, the Company will make generally available to its security holders and to the Representative an earnings statement or statements of the Company and its Subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act.

(k) The Company will furnish to the Representative and counsel for the Underwriters signed copies of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act, as many copies of each Preliminary Prospectus and the Prospectus and any supplement thereto as the Representative may reasonably request. The Company shall cause commercial copies of the U.S. Prospectus and of the Canadian Prospectus in the English and French languages to be delivered to the Underwriters, without charge, in such numbers and in such places as the Underwriters may reasonably request. The Company will use to its reasonable best efforts to effect such delivery as soon as possible and not later than 12:00 p.m., Toronto time, on the first Business Day immediately following the date of receipt of the MRRS decision document with respect to the Canadian Prospectus. The Company will use its reasonable best efforts to effect the delivery of commercial copies of any Supplementary Material required to be delivered, on request to the Underwriters or to any purchaser of Securities.

(l) The Company will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representative may designate and will maintain such qualifications in effect so long as required for the distribution of the Securities; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities or taxation, in any jurisdiction where it is not now so subject.

(m) The Company will not, without the prior written consent of the Representative, offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any affiliate of the Company or any person in privity with the Company or any affiliate of the Company), directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any other shares of Common Stock or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock; or publicly announce an intention to effect any such transaction, for a period of 90 days after the date of this Agreement, provided, however, that the Company may (i) issue and sell shares of Common Stock pursuant to any employee stock option plan (and may issue options thereunder), share ownership plan or dividend reinvestment plan of the Company in effect at the Execution Time; (ii) and the Company may issue shares of Common Stock upon the conversion of securities or the exercise of warrants outstanding at the Execution Time and disclosed in the Prospectus; and (iii) Shares of Common Stock held in escrow as of the Execution Time may be released from such escrow in accordance with their escrow terms.

(n) Except where such non-compliance would not have a Material Adverse Effect, the Company will comply with all applicable securities and other applicable laws, rules and regulations, including, without limitation, the Sarbanes Oxley Act and the FCPA and use its best efforts to cause the

18 Company’s directors and officers, in their capacities as such, to comply with such laws, rules and regulations, including, without limitation, the provisions of the Sarbanes Oxley Act, and the FCPA.

(o) The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

23 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, 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 any untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Securities as originally filed or in any amendment thereof, or in the U.S. Preliminary Prospectus, the Canadian Preliminary Prospectus, the Canadian Final Prospectus or the Prospectus, or in any amendment thereof or supplement thereto, 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) required to be stated therein or necessary to make the statements therein not misleading, 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 and the Selling Shareholders 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 the Representative or their counsel, specifically for inclusion therein; and provided further that the foregoing indemnity agreement with respect to the Preliminary U.S. Prospectus or Canadian Preliminary Prospectus shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased Securities, any person controlling such Underwriter or any affiliate of such Underwriter, if a copy of the U.S. Prospectus or Canadian Prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto), was not sent or given by or on behalf of such Underwriter to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the Securities to such person, and if such U.S. Prospectus or Canadian Prospectus (as so amended or supplemented) was previously furnished to such Underwriter and would have cured the defect giving rise to such losses, claims, damages or liabilities. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Each of the Selling Shareholders severally and not jointly 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, 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 any untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Securities as originally filed or in any amendment thereof, or in the U.S. Preliminary Prospectus, the Canadian Preliminary Prospectus, the Canadian Final Prospectus or the Prospectus, or in any amendment thereof or supplement thereto, 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) required to be stated therein or necessary to make the statements therein not misleading, 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 such Selling Shareholder will only 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 or on behalf of such Selling Shareholder specifically for inclusion specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Selling Shareholders may otherwise have.

(c) Each Selling Shareholder severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls the Company or any Underwriter within the meaning of either the Act or the Exchange Act and each Selling Shareholder, if any, to the same extent as the foregoing indemnity from the Company and the Selling Shareholders to each Underwriter, but only with reference to written information furnished to the Company by or on behalf of such Selling Shareholder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity will be in addition to any liability which any Selling Shareholder may otherwise have.

(d) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act and each Selling Shareholder, to the same extent as the foregoing indemnity set out in 8(a) to each Underwriter, but only with reference to written information relating to such Underwriter or to the offering furnished to the Company by or on behalf of such Underwriter through the Representative specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Company and each Selling Shareholder acknowledge that the statements set forth in the last paragraph of the cover page regarding delivery of the Securities and, under the heading “Underwriting,” (i) the list of Underwriters and their respective participation in the sale of the Securities, (ii) the sentences related to concessions and reallowances, and (iii) the paragraph related to stabilization, syndicate covering transactions and penalty bids in any Preliminary Prospectus and the Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus or the Prospectus.

(e) 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 so to notify the indemnifying party: (i) will not relieve it from liability under paragraph (a), (c) or (d) 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), (c) or (d) 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

25 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 the Representative in the case of parties indemnified pursuant to paragraph (a) and by the Company in the case of parties indemnified pursuant to paragraph (c) or (d). 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.

(f) In the event that the indemnity provided in paragraph (a), (c) or (d) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company, the Selling Shareholders, severally and not jointly, and the Underwriters, severally and not jointly, agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Company, one or more of the Selling Shareholders 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, by the Selling Shareholders and by the Underwriters from the offering of the Securities; 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 Securities) be responsible for any amount in excess of the Underwriting Fee applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company, the Selling Shareholders, severally and not jointly, 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, of the Selling Shareholders 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 and by a Selling Shareholder shall be deemed to be equal to the total net proceeds from the offering and sale of the Securities (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, the Selling Shareholders 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, the Selling Shareholders 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 (f), no person guilty of fraudulent misrepresentation

26 (within the meaning of Section 11(f) 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 (f).

(g) The liability of each Selling Shareholder under such Selling Shareholder’s representations and warranties contained in Section 1 hereof and under the indemnity and contribution agreements contained in this Section 8 shall be limited to an amount equal to the initial public offering price of the Securities sold by such Selling Shareholder to the Underwriters. The Company and the Selling Shareholders may agree, as among themselves and without limiting the rights of the Underwriters under this Agreement, as to the respective amounts of such liability for which they each shall be responsible.

9 Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Securities set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter, the Selling Shareholders or the Company. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representative shall determine in order that the required changes in the Registration Statement and the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company, the Selling Shareholders and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10 Termination. Each Underwriter is entitled to terminate its obligation to purchase the Securities 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 (other than an inquiry, action, suit, investigation or proceeding or order based solely upon the activities of the Underwriters), or there is any change of any Laws, or interpretation or administration thereof, which, in the opinion of any of the Underwriters, operates to prevent or restrict the distribution of the Securities in the United States or in any of the Canadian Qualifying Jurisdictions or would prevent or restrict trading in the Securities of the Company or would reasonably be expected to have a significant adverse effect on the market price or value of the Securities;

(b) there occurs any material change, any other change, event or fact contemplated by Section 5(i)(g) which, in the reasonable opinion of that Underwriter, could be expected to result in the

27 purchasers of a material number of Securities exercising their right under securities Laws to withdraw from or rescind their purchase thereof or sue for damages in respect thereof or which could reasonably be expected to have a significant adverse effect on the market price or value of the Securities or any of them;

(c) the state of the financial markets is such that in the reasonable opinion of that Underwriter, the Securities 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, materially adversely affects or may materially 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 Securities; or

(e) there is announced any change or proposed change in the income tax laws of the United States or Canada or the interpretation or administration thereof and such change would, in the reasonable opinion of an Underwriter, acting in good faith and after consultation with the Company, be expected to have a significant adverse effect on the marketability of the Securities.

In addition to the foregoing, this Agreement shall be subject to termination in the absolute discretion of the Representative, 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 Commissions, the TSX or AMEX, or (y) the TSX shall have been suspended or limited or minimum prices shall have been established on AMEX or the TSX, (ii) a banking moratorium shall have been declared either by Federal, or Pennsylvania State or Canadian authorities, or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States or Canada of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representative, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Prospectus (exclusive of any supplement thereto).

If this Agreement is properly terminated by any of the Underwriters pursuant to Section 10 of this Agreement, 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 8 and Section 5(i)(q) 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 Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers, of each Selling Shareholder and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any Selling Shareholder or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive
