The Common Shares to be sold by the Selling Shareholders are referred to herein as the “Offered Shares”.

The Company shall, under the applicable laws of the Qualifying Provinces (as hereinafter defined), (i) as soon as possible and in any event by 3:15 p.m. (Toronto time) on May 21, 2003, prepare and file, and (ii) as soon as possible and in any event by 4:30 p.m. (Toronto time) on May 21, 2003, obtain an MRRS Decision Document dated the date of filing issued by the Reviewing Authority (as hereinafter defined), in its capacity as principal regulator pursuant to NP 43-201 evidencing that a receipt

The Company has identified the British Columbia Securities Commission (the “Reviewing Authority”) as its principal regulator in respect of the proposed distribution of the Offered Shares. The Company shall also, immediately after the filing of the Canadian Preliminary Prospectus, but in any event no later than 3:15 p.m. (Toronto time) on May 21, 2003, prepare and file pursuant to the multi-jurisdictional disclosure system with the United States Securities and Exchange Commission (the “Commission”) a registration statement on Form F-10 covering the registration of the Offered Shares under the United States Securities Act of 1933, as amended, and the applicable rules and regulations thereunder adopted by the Commission (the “Act”), including the Canadian Preliminary Prospectus in the English language (with such deletions therefrom and additions thereto as are permitted or required by Form F-10 and the applicable rules and regulations of the Commission) (the “U.S. Preliminary Prospectus”). Such registration statement on Form F-10, including the exhibits thereto and the documents incorporated by reference therein, as amended at the time it becomes effective, is herein called the “Registration Statement”.

The Company shall, under the applicable laws of the Qualifying Provinces, (i) as soon as possible after any comments of the Qualifying Authorities have been satisfied and in any event by 4:00 p.m. (Toronto time) on May 29, 2003 (or in any case, by such later date or dates as may be determined by the Underwriters in their sole discretion), prepare and file, and (ii) as soon as possible and in any event by 4:30 p.m. (Toronto time) on May 29, 2003, obtain an MRRS Decision Document dated the date of filing issued by the Reviewing Authority, in its capacity as principal regulator pursuant to NP 43-201, evidencing that a receipt has been issued by the Qualifying Authorities in each Qualifying Province in respect of, in each case, a final short form prospectus of the Company relating to the Offered Shares, including the documents incorporated by reference in the English and French languages, as applicable (the “Canadian Final Prospectus”), and other related documents in respect of the proposed distribution of the Offered Shares. The Company shall also, immediately after the filing of the Canadian Final Prospectus but no later than 4:00 p.m. (Toronto time) on May 29, 2003 (or in any case, by such later date or dates as may be determined by the Underwriters in their sole discretion), prepare and file pursuant to the multi-jurisdictional disclosure system with the Commission, an amendment to the Registration Statement, including the Canadian Final Prospectus in the English language (with such deletions therefrom and additions thereto as are permitted or required by Form F-10 and the applicable rules and regulations of the

Commission) and shall use its best efforts to cause the Registration Statement to become effective under the Act.

The Company shall prepare and file with the Commission an Appointment of Agent for Service of Process and Undertaking for the Company on Form F-X in conjunction with the initial filing of the Registration Statement (the “Company Form F-X”).

			Laws or any permit, license or approval, any related constraints on operating activities and potential liabilities to third parties) would not, singularly or in the aggregate, have a Material Adverse Effect, or be required to be disclosed in the Prospectuses.

	(u)		The Company or one of its subsidiaries owns or possesses, or can acquire on reasonable terms, adequate patents, patent rights, licenses, inventions, copyrights, know how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential

			information, systems or procedures), trademarks, service marks, trade names or other intellectual property (collectively, “Intellectual Property”) necessary to carry on the business now operated by the Company and its subsidiaries, and neither the Company nor any of its subsidiaries has received any notice or is otherwise aware of any infringement of or conflict with asserted rights of others with respect to any Intellectual Property or of any facts or circumstances which would render any Intellectual Property invalid or inadequate to protect the interest of the Company or any of its subsidiaries therein, and which infringement or conflict (if the subject of any unfavourable decision, ruling or finding) or invalidity or inadequacy, individually or in the aggregate, would result in a Material Adverse Effect.

	(v)		Neither the Company nor any of its subsidiaries has taken, directly or indirectly, any action which was designed to or which has constituted or which might reasonably be expected to cause or result in stabilization or manipulation of the price of any security of the Company or, except as permitted by this Agreement, facilitate the sale or resale of the Offered Shares.

	(x)		The consolidated financial statements included in the Prospectuses, together with the related schedules, if any, and notes, present fairly the financial position of the Company and its consolidated subsidiaries at the dates indicated and the consolidated statements of income and retained earnings and cash flows of the Company and its consolidated subsidiaries for the periods specified; such financial statements have been prepared in accordance with generally accepted accounting principles in Canada (“Canadian GAAP”) applied on a consistent basis throughout the periods involved and, except for the interim consolidated financial statements included in the Prospectuses, have been reconciled to generally accepted accounting principles in the United States of America (“U.S. GAAP”) in accordance with Item 18 of Form 20-F under the Exchange Act.

	(y)		No labour dispute with the employees of the Company or any subsidiary exists or, to the knowledge of the Company, is imminent, and the Company is not aware of any existing or imminent labour

			disturbance by the employees of any of its or any subsidiary’s principal suppliers, manufacturers, customers or contractors, which, in either case, may reasonably be expected to result in a Material Adverse Effect.

	(z)		Except as disclosed in the Prospectuses, neither the Company nor any of its subsidiaries is a party to any contract, agreement or understanding with any officer, director, employee, insider or any other person not dealing at arm’s length with the Company which is required to be disclosed under the Act or applicable Canadian Securities Laws.

	(cc)		The French language version of the Canadian Prospectus, including the financial statements and other financial data contained therein, is in all material respects a complete and proper translation of the English language versions thereof, and is not susceptible of any materially different interpretation with respect to any material matter contained therein.

Any certificate signed by any officer of the Company and delivered to the Representatives or a Selling Shareholder or counsel for the Underwriters or the Selling Shareholders in connection with the offering of the Offered Shares shall be deemed a representation and warranty by the Company, as to matters covered thereby, to each Underwriter or to each Selling Shareholder, as the case may be.

	(b)		For greater certainty, it is the intention of the parties that the Offered Shares to be delivered and sold by each Selling Shareholder pursuant to the terms of this Agreement shall be Common Shares that will be issued to NOVA and NPL following the date of this Agreement and prior to the Closing Date, pursuant to a series of transactions to be entered into among NOVA, NPL and the Company (the “Reorganization Transaction”). In the event that the Reorganization Transaction is not completed on or before the Closing Date, in order to meet their respective obligations hereunder, each Selling Shareholder shall be entitled to sell Common Shares otherwise acquired by them, including any Common Shares owned by them on the date hereof. Nothing in this Agreement shall be construed so as to preclude a Selling Shareholder from dealing in any way with the Common Shares held by it between the date of this Agreement and the Closing Date, including without limitation, a disposition of its currently owned Common Shares pursuant to the Reorganization Transaction.

	(c)		In consideration for the Underwriters’ agreement to purchase the Offered Shares, and in consideration for their services hereunder, NOVA, on its own behalf and on behalf of NPL, shall pay to the Representatives, for the account of the Underwriters, a fee of Cdn$0.532 per Offered Share in the case of Offered Shares sold by the Underwriters in Canadian dollars and a fee of US$0.394 per Offered

Share in the case of Offered Shares sold by the Underwriters in U.S. dollars (collectively, the “Underwriting Fee”).

Delivery and Payment.

	(a)		Delivery of and payment for the Offered Shares hereof shall be made at 6:00 a.m. (Vancouver time) on June 5, 2003, or at such time on such later date not more than three Business Days after the foregoing date as the Underwriters shall designate, which date and time may be postponed by agreement between the Underwriters, the Selling Shareholders and the Company or as provided in Section 10 hereof, provided that such date shall not in any event be later than July 5, 2003 (such date and Closing Date and payment for the Offered Shares being herein called the “Closing Date”).

	(b)		Delivery of the Offered Shares shall be made to the Representatives for the respective accounts of the Underwriters against payment through the Representatives of the Canadian and U.S. dollar amounts representing the Purchase Price to NOVA by electronic funds transfers, wire transfers, or through the facilities of The Depository Trust Company and/or The Canadian Depository for Securities Ltd., at the option of the Representatives, payable in same-day funds to the accounts specified by NOVA. It is understood that (i) NPL has authorized NOVA, for its own account, to accept delivery of, and provide a receipt for, the purchase price for the Offered Shares, and (ii) each Underwriter has authorized the Representatives, for its account, to accept delivery of, provide a receipt for, and make payment of the purchase price for, the Offered Shares which it has agreed to purchase. The Representatives, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Offered Shares to be purchased by any Underwriter whose funds have not been received by the Closing Time, but such payment shall not relieve such Underwriter from its obligations hereunder.

	(c)		At the Closing Time, delivery of the Offered Shares by the Selling Shareholders shall be made through the facilities of The Depository Trust Company and/or The Canadian Depository for Securities Ltd., or, in the event not practicable, the Selling Shareholders shall duly and validly deliver to the Underwriters one or more definitive share certificate(s) representing the Offered Shares to be sold by them hereunder, endorsed in such name or names as the Representatives will direct the Selling Shareholders in writing not less than 24 hours prior to such Closing Time. The Company and the Selling

			Shareholders shall, prior to the Closing Time, make all necessary arrangements for the exchange of such definitive certificate(s), at the principal offices of CIBC Mellon Trust Company in the City of Vancouver for one or more global share certificates representing the Offered Shares registered in the name of The Canadian Depository for Securities Ltd. or The Depository Trust Company or such other names as shall be designated by the Underwriters not less than 24 hours prior to the Closing Time. NOVA shall pay all fees and expenses payable to CIBC Mellon Trust Company in connection with the preparation, delivery, certification and exchange of the definitive share certificates contemplated by this paragraph and the fees and expenses payable to or incurred by CIBC Mellon Trust Company in connection with the initial or additional transfers as may be required in the course of the distribution of the Offered Shares. For greater certainty, the Company shall not be entitled to receive any portion of the purchase price of any Offered Shares to be paid by the Underwriters hereunder.

	(d)		Concurrently with the payment by the Representatives of the purchase price for the Offered Shares, NOVA, on its own behalf and on behalf of NPL, shall pay to the Underwriters the Canadian and U.S. dollar amounts representing the Underwriting Fee with respect to the Offered Shares, through and as requested by the Representatives, by certified cheques, bank drafts, wire transfers, or through the facilities of The Depository Trust Company and/or The Canadian Depository for Securities Ltd., at the option of the Representatives, payable in same-day funds to the accounts specified by the Representatives.

5.		Offering by Underwriters. It is understood that the Underwriters propose to offer the Offered Shares for sale to the public as set forth in the Canadian Prospectus and U.S. Prospectus. The Representatives shall give prompt written notice, on behalf of the Underwriters, to the Company when, in the opinion of the Underwriters, they have ceased distribution to the public of the Offered Shares. Such notice will specify the total proceeds realized in each of the Provinces of Canada from such distribution.

	(b)		Contemporaneously with, or immediately prior to, the filing of the Canadian Prospectus, the Company shall deliver to the Underwriters, without charge, in Vancouver: (i) a copy of the Canadian Prospectus, including all documents incorporated by reference, in each of the English and French language, as applicable, signed and certified as required by the Canadian Securities Laws in the Qualifying Provinces; (ii) a copy of any other document filed by the Company under the Canadian Securities Laws; (iii) opinions of ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP, Canadian counsel to the Company, dated, in the case of the Canadian Preliminary Prospectus, as of the date of the Canadian Preliminary Prospectus and, in the case of the Canadian Final Prospectus, as of the date of the Canadian Final Prospectus, in form and substance satisfactory to the Underwriters, addressed to the Company, the Selling Shareholder, its Canadian counsel, the Underwriters and their Canadian counsel, to the effect that the French language version of the Canadian Preliminary Prospectus or the Canadian Final Prospectus, as the case may be, including all documents incorporated by reference, except for the unaudited financial statements and audited financial statements of the Company, the schedules and notes thereto and the related auditors’ report on such statements as well as the other financial information forming part of the management’s discussion and analysis of financial condition and result of operations included in the documents incorporated by reference (collectively, “Financial Information”) as to which no opinion need be expressed by such counsel, is in all material respects a complete and accurate translation of the English language version thereof; (iv) an opinion of KPMG LLP dated, in the case of the Canadian Preliminary Prospectus, as of the date of the Canadian Preliminary Prospectus and, in the case of the Canadian Final Prospectus, as of the date of the Canadian Final Prospectus, in form and substance satisfactory to the Underwriters, addressed to the Underwriters, the Company, the Selling Shareholders and their respective Canadian counsel, to the effect that the French language version of the Financial Information contained in the Preliminary Canadian Prospectus or the Canadian Final Prospectus, as the case may be is, in all material respects, a complete and proper translation of the English language version thereof; and (v) a “long-form” comfort letter of KPMG LLP, dated as of the date of the Canadian Final Prospectus (with the requisite procedures to be completed by such auditors no later than two Business Days prior to the date of the Canadian Final Prospectus), addressed to the

			Underwriters, the Selling Shareholders and the directors of the Company, in form and substance satisfactory to the Underwriters, with respect to certain financial and accounting information relating to the Company in the Canadian Final Prospectus, including all documents incorporated by reference into the Canadian Final Prospectus and the auditors’ comfort letters addressed to the Qualifying Authorities in the Qualifying Provinces. The deliveries set forth in (i) and (ii) above shall also constitute the Company’s consent to the Underwriters’ use of the Canadian Prospectus for the distribution of the Offered Shares in the Qualifying Provinces in compliance with the provisions of this Agreement and the Canadian Securities Laws.

	(c)		During the period from the date of this Agreement to the date of completion of the distribution of the Offered Shares, the Company will notify the Underwriters and the Selling Shareholders promptly, and confirm the notice in writing, (i) when any amendment to the Registration Statement shall have been filed with the Commission or shall have become effective, and when any amended Canadian Prospectus, U.S. Prospectus or any Supplementary Material shall have been filed, in which case the Company shall deliver to the Underwriters all signed and certified copies of such amendment in the English and French languages, as applicable, along with all documents similar to those referred to in Section 6(b)(i), (ii), (iii) and (iv); (ii) of the receipt of any comments from any Qualifying Authority or the Commission; (iii) of any request by any Qualifying Authority to amend or supplement the Canadian Prospectus or for additional information or of any request by the Commission to amend the Registration Statement or to amend or supplement the U.S. Prospectus or for additional information; (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order from any Qualifying Authority preventing or suspending the use of the Canadian Prospectus; or of the prevention or suspension of the qualification of the Offered Shares for offer or sale in any jurisdiction, or of the institution or threatening of any proceeding for that purpose; and (v) of the issuance by any Qualifying Authority or any stock exchange or any court of any order having the effect of ceasing or suspending the distribution of the Offered Shares or the trading in the Common Shares of the Company, or of the institution or threatening of any proceeding for any such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or of any order preventing or suspending such use or such order ceasing or suspending the distribution of the Offered Shares or

			the trading in the Common Shares of the Company and, if any such order is issued, to obtain as soon as possible the withdrawal thereof.

	(e)		As soon as practicable, the Company will make generally available to its security holders and to the Underwriters 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.

	(f)		The Company and the Selling Shareholders will furnish to the Underwriters and counsel for the Underwriters, without charge, signed copies of the Registration Statement (including any exhibits thereto) and so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act, as many commercial copies of each Canadian Preliminary Prospectus and the U.S. Preliminary Prospectus and the Canadian Final Prospectus and the U.S. Prospectus and any amendment or supplement thereto as the Underwriters may reasonably request, including any amendment pursuant to Section 6(m) of this Agreement.

	(g)		The Company will arrange, if necessary, for the qualification of the Offered Shares for distribution under the laws of such jurisdictions as the Underwriters may designate and will maintain such qualifications in effect so long as required for the distribution of the Offered Shares; 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 Offered Shares in any jurisdiction where it is not now so subject. The Company will also supply the Underwriters with such information as is necessary for the determination of the legality of the Offered Shares for investment

			under the laws of such jurisdictions as the Underwriters may reasonably request.

	(h)		The Company will not, without the prior written consent of the Representatives, which consent shall not be unreasonably withheld, 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 of its subsidiaries or any person acting on behalf of the Company or any of its subsidiaries, directly or indirectly, any Common Shares or rights thereto including: (i) the filing (or participation in the filing) of (A) any preliminary prospectus or prospectus under Canadian Securities Laws, (B) any registration statement with the Commission, and (C) any offering memorandum or other offering document, and (ii) 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, in respect of any Common Shares or any securities convertible into, or exercisable, or exchangeable for, Common Shares; or publicly announce an intention to effect any such transaction, for a period from the date of this Agreement until 90 days after the Closing Date (the “Lock-Up Period”), provided, however, that the Company may (iii) grant stock options, award restricted share units and deferred shares units and issue and sell Common Shares pursuant to any director, officer or employee stock compensation, stock option or stock ownership plans of the Company in effect at the Execution Time; (iv) issue Common Shares issuable upon the conversion of securities or the exercise of warrants outstanding at the Execution Time; (v) complete the Reorganization Transaction; and (vi) purchase Common Shares, directly or indirectly, as contemplated by the Repurchase Transaction.

	(j)		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 Offered Shares.

The Company and the Selling Shareholders shall in good faith discuss with the Underwriters any fact or change in circumstances (actual, anticipated, contemplated or threatened, financial or otherwise) which is of such a nature that there is reasonable doubt whether written notice need be given under this paragraph.

	(n)		The Company, during the period when the U.S. Prospectus, is required to be delivered under the Act or the Exchange Act in respect of the offer and sale of the Offered Shares, will file all documents required to be filed by the Company with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act and the rules and regulations of the Commission thereunder.

	(o)		The Company agrees to apply forthwith following the Execution Time for, and to use its best efforts to obtain (to the extent not already applied for or obtained) such exemptive relief from Canadian Securities Laws applicable in the Province of Alberta from the issuer bid requirements as is necessary or desirable to enable the Company and the Selling Shareholders to complete the Repurchase Transaction and the Reorganization Transaction (the “Repurchase Relief”). Forthwith following the Execution Time, the Company shall give notice, in compliance with Canadian Securities Laws, of a special meeting of the holders of Common Shares, to be held as soon as reasonably practical following the giving of such notice but in any event no later than July 15, 2003, for the purpose of obtaining the approval of the Repurchase Transaction (the “Repurchase Approval”).

			fairness, from a financial perspective, of the Repurchase Transaction, to the holders of Common Shares other than the Selling Shareholders.

	(xi)		Insofar as matters of the laws of the Province of British Columbia and the federal laws of Canada applicable therein are concerned, the Registration Statement, and the filing of the Registration Statement with the Commission have been duly authorized by and on behalf of the Company; and the Registration Statement have been duly executed pursuant to such authorization by and on behalf of the Company;

for a trust governed by a registered retirement savings plan, registered retirement income fund, a deferred profit sharing plan or a registered educations savings plan; and as of the date of issue, the Offered Shares will not constitute “foreign property” for the purposes of Part XI of the Income Tax Act (Canada).

		obligations of the Underwriters set forth in Section 7 of this Agreement is not satisfied (otherwise than by reason of a failure of the Company, as a result of its wilful misconduct or negligence, to perform any agreement herein or comply with any provision hereof), because of any termination pursuant to Section 11 of this Agreement or because of any refusal, inability or failure on the part of the Selling Shareholders to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, NOVA, on behalf of the Selling Shareholders, will reimburse the Underwriters through the Representatives on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel to the Underwriters) that shall have been incurred by them in connection with the proposed sale of the Offered Shares. The Company will make such reimbursement to the Underwriters if the sale of the Offered Shares is not consummated by reason of a failure of the Company, as a result of its wilful misconduct or negligence, to perform any agreement herein or comply with any provision hereof, other than by reason of a default by any of the Underwriters.

9.		Indemnification and Contribution

(a)

The Company agrees to indemnify and hold harmless each Underwriter, the Selling Shareholders and their respective directors, officers, employees, agents and affiliates and each person who controls any Underwriter or Selling Shareholder within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, jointly or severally, to which they or any of them may become subject under the Act, Canadian Securities Laws, the Exchange Act or other Canadian federal or provincial, United States federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) (i) arise out of or are based upon 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 any of the Prospectuses, 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 required to be stated therein or necessary to make the statements therein not misleading, (ii) any misrepresentation or alleged misrepresentation contained in the Canadian Prospectus; and (iii) any breach by the Company of its representations, warranties, covenants or obligations to be complied with under this Agreement, and agrees 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 and in conformity with written information furnished to the Company by (A) NOVA specifically for inclusion in such material (or any amendment or supplement thereto) relating to NOVA and its subsidiaries or (B) the Representatives on behalf of any Underwriter specifically for inclusion in such material (or any amendment or supplement thereto) relating to the Underwriters; provided further, that with respect to any untrue statement or omission of material fact made in any Canadian Preliminary Prospectus, U.S. Preliminary Prospectus, the Canadian Final Prospectus, or the U.S. Prospectus, the indemnity contained in this Section 9(a) shall not enure to the benefit of any Underwriter from whom the person asserting any such loss, claim, damage or liability purchased the Offered Shares concerned, to the extent that any such loss, claim, damage or liability of such Underwriter occurs under the circumstance where it shall have been determined by a court of competent jurisdiction by final and nonappealable judgment that (w) the Company had previously furnished copies of the Canadian Prospectus or the U.S. Prospectus to the Underwriters, (x) delivery of the Canadian Prospectus or the U.S. Prospectus was required by the Act to be made to such person, (y) the untrue statement or omission of a material fact contained in the Canadian Preliminary Prospectus or the U.S. Preliminary Prospectus was corrected in the Canadian Final Prospectus or the U.S. Prospectus and (z) there was not sent or given to such person, at or prior to the written confirmation of the sale of such securities to such person, a copy of the Canadian Final Prospectus or the U.S. Prospectus. This indemnity will be in addition to any liability which the Company may otherwise have.

	(b)		NOVA, on behalf of the Selling Shareholders, agrees to indemnify and hold harmless each Underwriter, the Company and their respective directors, officers, employees, agents and affiliates and each person who controls any Underwriter or the Company within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, jointly or severally, to which they or any of them may become subject under the Act, Canadian Securities Laws, the Exchange Act or other Canadian federal or provincial, United States federal or state 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 any information provided in writing by the Selling Shareholders for inclusion in the Registration Statement for the registration of the Offered Shares as originally filed or in any amendment thereof, or in any of the Prospectuses, 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 required to be stated therein or necessary to make the statements therein not misleading, (ii) any misrepresentation or alleged misrepresentation contained in any information provided in writing by the Selling Shareholders for inclusion in the Canadian Preliminary Prospectus or the Canadian Final Prospectus, and (iii) any breach by the Selling Shareholders of their respective representations, warranties, covenants or obligations to be complied with under this Agreement, and agrees 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 with respect to any untrue statement or omission of material fact made in any Canadian Preliminary Prospectus, U.S. Preliminary Prospectus, the Canadian Final Prospectus or the U.S. Prospectus, the indemnity contained in this Section 9(b) shall not enure to the benefit of any Underwriter from whom the person asserting any such loss, claim, damage or liability purchased the Offered Shares concerned, to the extent that any such loss, claim, damage or liability of such Underwriter occurs under the circumstance where it shall have been determined by a court of competent jurisdiction by final and nonappealable judgment that (w) the Company had previously furnished copies of the Canadian Prospectus or the U.S. Prospectus to the Representatives, (x) delivery of the Canadian Prospectus or the U.S. Prospectus was required by the Act to be made to such person, (y) the untrue statement or omission of a material fact contained in the Canadian Preliminary Prospectus or the U.S. Preliminary Prospectus was corrected in the Canadian Final Prospectus or the U.S. Prospectus and (z) there was not sent or given to such person, at or prior to the written confirmation of the sale of such securities to such person, a copy of the Canadian Final Prospectus or the U.S. Prospectus. This indemnity will be in addition to any liability which the Selling Shareholders may otherwise have. The Company and the Underwriters acknowledge that the information included in the first and second paragraphs under the heading “Selling Shareholder” contained in any Canadian Preliminary Prospectus, U.S. Preliminary Prospectus, Canadian Prospectus and U.S. Prospectus constitute the only information furnished in writing by or on behalf of

			the Selling Shareholders for inclusion in any Preliminary Canadian Prospectus, U.S. Preliminary Prospectus, Canadian Prospectus or U.S. Prospectus.

	(c)		Each of the Underwriters severally agrees to indemnify and hold harmless the Company, the Selling Shareholders, their respective directors, each of their officers who signs the Registration Statement or the Canadian Prospectus, and each person who controls the Company or the Selling Shareholders within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, including 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, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives 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 the Selling Shareholders acknowledge that (i) the statements set forth in the last paragraph of the cover page regarding delivery of the Offered Shares and, under the heading “Plan of Distribution”, and (ii) the paragraphs related to stabilization, syndicate covering transactions and penalty bids contained in any Canadian Preliminary Prospectus, U.S. Preliminary Prospectus, Canadian Prospectus and U.S. Prospectus constitute the only information furnished in writing by or on behalf of the Underwriters for inclusion in any Preliminary Canadian Prospectus, U.S. Preliminary Prospectus, Canadian Prospectus or U.S. Prospectus.

	(d)		Promptly after receipt by an indemnified party under this Section 9 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 9, 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) or (b) 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 defences 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) or (b) 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 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 that there may be legal defences 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 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. It is understood, however, that the Company shall, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of only one separate firm of attorneys (in addition to any local counsel) at any time for all such Underwriters and controlling persons, which firm shall be designated in writing by the Representatives. 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.

	(e)		In the event that the indemnity provided in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company, NOVA (on its behalf and on behalf of NPL)

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, the Selling Shareholders and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect: (i) as between the Selling Shareholders and the Underwriters, the relative benefits received by the Selling Shareholders on the one hand and by the Underwriters on the other hand from the offering of the Offered Shares; (ii) as between the Company and the Selling Shareholders the relative fault of the Company on the one hand and the Selling Shareholders on the other hand; and (iii) as between the Company and the Underwriters, on the relative fault of the Company on the one hand and the Underwriters on the other hand; 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 Offered Shares) be responsible for any amount in excess of the underwriting discount or commission applicable to the Offered Shares purchased by such Underwriter hereunder. If the allocation provided for in item (i) in the immediately preceding sentence is unavailable for any reason, NOVA (on its behalf and on behalf of NPL) on the one hand and the Underwriters on the other hand, 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 such Selling Shareholders on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Selling Shareholders shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by them, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Canadian Prospectus and the U.S. Prospectus. 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, with respect to item (ii) above, by the Company on the one hand or the Selling Shareholders on the other, with respect to item (iii) above, by the Company on the one hand or the Underwriters on the other, and with respect to item (i) above, in the event applicable, by the Selling Shareholders on the one hand and the Underwriters on the other, 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 (e), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) or misrepresentation under Canadian Securities Laws shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation or misrepresentation. For purposes of this Section 9, 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 or the Canadian Prospectus 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 (e).

10.

Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Offered Shares 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 and not jointly to take up and pay for (in the respective proportions which the percentage of Offered Shares set forth opposite their names in Schedule A hereto bears to the aggregate percentage of Offered Shares set forth opposite the names of all the remaining Underwriters) the Offered Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Offered Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 12.5% of the aggregate amount of Offered Shares set forth in Schedule A hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Offered Shares, and if such nondefaulting Underwriters do not purchase all the Offered Shares, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 10, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement, the Canadian Prospectus or the U.S. 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.

11.		Termination.

(a)

This Agreement shall be subject to termination by any Underwriter (with respect to itself only) in the absolute discretion of such Underwriter, by notice given to the Company and the Selling Shareholders at any time prior to the Closing Time in accordance with paragraph 11(c), if, at any time prior to such Closing Time:

	(i)		any enquiry, action, suit, investigation or other proceeding whether formal or informal is instituted, threatened or announced or any order is made by any federal, provincial or other governmental authority in relation to the Selling Shareholders or the Company, which, in the reasonable opinion of the Underwriters or any of them, operates to prevent or restrict the distribution of the Offered Shares or the trading of the Common Shares;

	(ii)		there should occur any material change or a change in any material fact such as is contemplated in paragraph 6(m) of this Agreement which results or, in the opinion of the Underwriters or any one of them, would be expected to have a significant adverse effect on the market price or value of the Offered Shares;

	(iii)		(A) trading in any of the Company’s common shares shall have been suspended by the Commission, the Reviewing Authority, or the Toronto Stock Exchange or the Nasdaq National Market or trading in securities generally on the Toronto Stock Exchange or the Nasdaq National Market shall have been suspended or limited or minimum prices shall have been established on any such exchanges, (B) a banking moratorium shall have been declared either by U.S. Federal, New York State or Canadian federal authorities, (C) a change or development involving a prospective change in Canadian taxation affecting the Offered Shares or the transfer thereof or the imposition of exchange controls by the United States or Canada, (D) there should develop, occur or come into effect or existence any event, action, state, condition or major financial occurrence of national or international consequence or any law or regulation which in the opinion of the Underwriters or any one of them seriously

adversely affects, involves, or will seriously adversely affect, or involve, the financial markets or the business, operations or affairs of the Company and its subsidiaries taken as a whole.

	(b)		The Selling Shareholders and the Company each agrees that all terms and conditions of this Agreement shall be construed as conditions and complied with so far as they relate to acts to be performed or caused to be performed by them, that they will use their best efforts to cause such conditions to be complied with, and that any breach or failure by the Selling Shareholders or the Company to comply with any such conditions shall entitle any of the Underwriters to terminate their obligations to purchase the Offered Shares by notice to that effect given to the Selling Shareholders and the Company at or prior to the Closing Time, unless otherwise expressly provided in this Agreement. The Underwriters may waive, in whole or in part, or extend the time for compliance with, any terms and conditions without prejudice to its rights in respect of any other of such terms and conditions or any other or subsequent breach or non-compliance, provided that any such waiver or extension shall be binding upon the Underwriters only if such waiver or extension is in writing and signed by the Representatives.

	(c)		The rights of termination contained in paragraphs 11(a) and (b) may be exercised by any of the Underwriters and are in addition to any other rights or remedies any of the Underwriters may have in respect of any default, act or failure to act or non-compliance by the Selling Shareholders or the Company in respect of any of the matters contemplated by this Agreement or otherwise. In the event of any such termination, there shall be no further liability on the part of the Underwriters to the Selling Shareholders and the Company or on the part of the Selling Shareholders and the Company to the Underwriters except in respect of any liability which may have arisen or may arise after such termination under paragraphs 8 and 9. A notice of termination given by an Underwriter under paragraphs 11(a) and (b) shall not be binding upon any other Underwriter.

12.

Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Selling Shareholders or their officers 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, the Selling Shareholders or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 9 of this Agreement, and will survive delivery of and payment for the
