Merrill Lynch, Pierce, Fenner & Smith Incorporated as Representatives of the several Underwriters c/o Merrill Lynch & Co. Merrill Lynch, Pierce, Fenner & Smith Incorporated World Financial Center, North Tower 250 Vesey Street, 6th Floor New York, NY 10281-1209 Ladies and Gentlemen: Aspreva Pharmaceuticals Corporation, a company continued under the British Columbia Business Corporations Act (the "Company") confirms its agreement with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch"), and each of the other Underwriters named in Schedule A hereto (collectively, the "Underwriters", which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom Merrill Lynch is acting as representatives (in such capacity, the "Representatives"), with respect to the issue and sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective numbers of Common Shares, without par value, of the Company ("Common Shares") set forth in said Schedule A and with respect to the grant by the Company to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of additional Common Shares to cover over-allotments, if any. The aforesaid Common Shares (the "Initial Securities") to be purchased by the Underwriters and all or any part of the Common Shares subject to the option described in Section 2(b) hereof (the "Option Securities") are hereinafter called, collectively, the "Securities". The Company understands that the Underwriters propose to make a public offering of the Securities in the United States and in each of the provinces of Canada upon the terms set forth in the U.S. Prospectus (as defined below) and the Canadian Prospectus (as defined below), 2 respectively, as soon as the Underwriters deem advisable after this Agreement has been executed and delivered. The Company and the Underwriters agree that up to _______ shares of the Securities to be purchased by the Underwriters (the "Reserved Securities") shall be reserved for sale by the Underwriters to certain eligible employees and persons having business relationships with the Company (the "Invitees"), as part of the distribution of the Securities by the Underwriters, subject to the terms of this Agreement, the applicable rules, regulations and interpretations of the National Association of Securities Dealers, Inc. and all other applicable laws, rules and regulations. To the extent that such Reserved Securities are not orally confirmed for purchase by Invitees by the end of the first business day after the date of this Agreement, such Reserved Securities may be offered to the public as part of the public offering contemplated hereby. The Company has filed with the United States Securities and Exchange Commission (the "Commission") a registration statement on Form F-1 (No. 333-122234), as amended, including the related preliminary prospectus or prospectuses, covering the registration of the Securities under the U.S. Securities Act of 1933, as amended (the "1933 Act"). Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of Rule 430A ("Rule 430A") of the rules and regulations of the Commission under the 1933 Act (the "1933 Act Regulations") and paragraph (b) of Rule 424 ("Rule 424(b)") of the 1933 Act Regulations. The information included in such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement at the time it became effective pursuant to paragraph (b) of Rule 430A is referred to as "Rule 430A Information." Each prospectus used in the United States before such registration statement became effective, and any prospectus that omitted the Rule 430A Information, that was used in the United States after such effectiveness and prior to the execution and delivery of this Agreement, is herein called a "U.S. preliminary prospectus." Such registration statement, including the exhibits and any schedules thereto, at the time it became effective, and including the Rule 430A Information, is herein called the "Registration Statement." Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the "Rule 462(b) Registration Statement," and after such filing the term "Registration Statement" shall include the Rule 462(b) Registration Statement. The final prospectus in the form first furnished to the Underwriters for use in connection with the offering of the Securities is herein called the "U.S. Prospectus." For purposes of this Agreement, all references to the Registration Statement, any U.S. preliminary prospectus, the U.S. Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR"). The Company has prepared and filed with the British Columbia Securities Commission in the province of British Columbia (the "Reviewing Authority") and with the securities regulatory authorities (the "Qualifying Authorities") in each of the other provinces of Canada (the "Qualifying Provinces") a preliminary PREP prospectus relating to the Securities (in the English and French languages, as applicable, the "Preliminary PREP Prospectus"), an amended and restated preliminary PREP prospectus relating to the Securities (in the English and French languages, as applicable, the "Amended Preliminary PREP Prospectus") and a second amended 3 and restated preliminary PREP prospectus relating to the Securities (in the English and French languages, as applicable, the "Second Amended Preliminary PREP Prospectus"). The Company has filed the Preliminary PREP Prospectus, the Amended Preliminary PREP Prospectus and the Second Amended Preliminary PREP Prospectus with the Reviewing Authority and the Qualifying Authorities pursuant to National Policy 43-201 - Mutual Reliance Review System for Prospectuses and Annual Information Forms and its related memorandum of understanding, and the Reviewing Authority is acting as principal regulator. The Company has also filed the Preliminary PREP Prospectus, the Amended Preliminary PREP Prospectus and the Second Amended Preliminary PREP Prospectus with the Reviewing Authority and the Qualifying Authorities pursuant to National Instrument 44-103 - Post-Receipt Pricing (the "PREP Procedures"). The Reviewing Authority has issued a preliminary Mutual Reliance Review System Decision Document for the Preliminary PREP Prospectus, the Amended Preliminary PREP Prospectus and the Second Amended Preliminary PREP Prospectus. In addition, the Company (A) has prepared and filed with the Reviewing Authority and the Qualifying Authorities, a final PREP prospectus relating to the Securities (in the English and French languages, as applicable, the "Base PREP Prospectus") which omits the PREP Information (as hereinafter defined) in accordance with the PREP Procedures, and (B) will prepare and file, promptly after the execution and delivery of this Agreement, with the Reviewing Authority and the Qualifying Authorities, in accordance with the PREP Procedures, a supplemented PREP prospectus setting forth the PREP Information (in the English and French languages, as applicable, the "Supplemented PREP Prospectus"). The information included in the Supplemented PREP Prospectus that is omitted from the Base PREP Prospectus and which is deemed under the PREP Procedures to be incorporated by reference in the Base PREP Prospectus as of the date of the Supplemented PREP Prospectus is referred to herein as the "PREP Information". The Preliminary PREP Prospectus, the Amended Preliminary PREP Prospectus, the Second Amended Preliminary PREP Prospectus and the Base PREP Prospectus are herein collectively called the "Canadian Preliminary Prospectus". The Base PREP Prospectus for which a final Mutual Reliance Review System Decision Document has been received from the Reviewing Authority on behalf of itself and the Qualifying Authorities, including the PREP information incorporated by reference therein, is herein referred to as the "Canadian Prospectus", except that, if, after the execution of this Agreement, a Supplemented PREP Prospectus containing the PREP Information is thereafter filed with the Reviewing Authority and the Qualifying Authorities, the term "Canadian Prospectus" shall refer to such Supplemented PREP Prospectus. Canadian securities laws (the "Canadian Securities Laws") means, collectively, the applicable securities laws of each of British Columbia and the Qualifying Provinces and the respective regulations and rules made under those securities laws together with all applicable policy statements, blanket orders and rulings of the Reviewing Authority and the Qualifying Authorities, as applicable, and the securities legislation and policies of each other relevant jurisdiction. The Company understands that a portion of the Securities may be offered and sold in a public offering in the Province of British Columbia and the Qualifying Provinces conducted through Merrill Lynch Canada Inc. (the "Sub-underwriter"), an affiliate of Merrill Lynch, 4 pursuant to the Canadian Prospectus. The Sub-underwriter, subject to the terms and conditions set forth herein, agrees and covenants with the Company to use reasonable efforts to sell the Securities in the Province of British Columbia and the Qualifying Provinces. Any Securities so sold will be purchased by the Sub-underwriter from Merrill Lynch at the Closing Time at a price equal to the purchase price as set forth in Schedule B hereto or such purchase price less an amount to be mutually agreed upon by the Sub-underwriter and Merrill Lynch, which amount shall not be greater than the underwriting commission as set forth in Schedule B hereto. SECTION 1. Representations and Warranties. (a) Representations and Warranties by the Company.

As used herein, a "Repayment Event" means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder's behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any subsidiary.

(xiii) Accuracy of Exhibits. There are no statutes, regulations, contracts or documents which are required to be described in the Registration Statement, the U.S. Prospectus or the Canadian Prospectus or to be filed as exhibits thereto which have not been so described and filed as required.

If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) or settlement of any claim in connection with any violation referred to in Section 6(e) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. (e) Indemnification for Reserved Securities. In connection with the offer and sale of the Reserved Securities, the Company agrees to indemnify and hold harmless the Underwriters, their Affiliates and selling agents and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, from and against any and all loss, liability, claim, damage and expense (including, without limitation, any legal or other expenses reasonably incurred in connection with defending, investigating or settling any such action or claim), as incurred, (i) arising out of the violation of any applicable laws or regulations of jurisdictions other than the United States and Canada where Reserved Securities have been offered; (ii) arising out of any untrue statement or alleged untrue statement of a material fact contained in any prospectus wrapper or other material prepared by or with the consent of the Company for distribution to Invitees in connection with the offering of the Reserved Securities or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (iii) caused by the failure of any Invitee to pay for and accept delivery of Reserved Securities which have been orally confirmed for purchase by any Invitee by the end of the first business day after the date of the Agreement; or (iv) related to, or arising out of or in connection with, the offering of the Reserved Securities. SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and 32 expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters and the Sub-underwriter on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters and the Sub-underwriter on the other hand in connection with the statements or omissions, or in connection with any violation of the nature referred to in Section 6(e) hereof, which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters and the Sub-underwriter on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting commission received by the Underwriters, in each case as set forth on the cover of the U.S. Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover. The relative fault of the Company on the one hand and the Underwriters and the Sub-underwriter on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the Sub-underwriter and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission, or any violation of the nature referred to in Section 6(e) hereof. The Company and the Underwriters and the Sub-underwriter agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters and the Sub-underwriter were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 7, no Underwriter and no Sub-underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter or the Sub-underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission. 33 No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person, if any, who controls an Underwriter or the Sub-underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter or Sub-underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement or the Canadian Prospectus, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint. The Sub-underwriter's obligation to contribute pursuant to this Section 7 is in proportion to the number of Initial Securities it purchased from Merrill Lynch, Pierce, Fenner & Smith Incorporated. SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries delivered pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any Sub-underwriter or controlling person, or by or on behalf of the Company, and shall survive delivery of the Securities to, and payment for the Securities by, the Underwriters and the Sub-underwriter. SECTION 9. Termination of Agreement. (a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the U.S. Prospectus (exclusive of any supplement thereto) and the Canadian Prospectus (exclusive of any supplement thereto), any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or Canada, or in the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in United States, Canadian or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission, the Reviewing Authority, any Qualifying Authority, any other securities commission or securities regulatory authority in Canada or the TSX or the NASDAQ National Market, or if trading generally on the New York Stock Exchange, the TSX, or in the NASDAQ National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the Reviewing Authority, any Qualifying Authority, any other securities commission or securities regulatory 34 authority in Canada, the National Association of Securities Dealers, Inc. or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or Canada, or (iv) if a banking moratorium has been declared by either United States federal, New York state or Canadian federal authorities. (b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect. SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the "Defaulted Securities"), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters or the Sub-underwriter, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then: (a) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased hereunder, the non-defaulting Underwriters or the Sub-underwriter shall be obligated, each severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters or the Sub-underwriter, or (b) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after Closing Time, the obligation of the Underwriters to purchase and of the Company to sell the Option Securities to be purchased and sold on such Date of Delivery, shall terminate without liability on the part of any non-defaulting Underwriter or the Sub-underwriter. No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default. In the event of any such default which does not result in a termination of this Agreement, or in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Company to sell the relevant Option Securities, as the case may be, either the Representatives or the Company shall have the right to postpone the Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the U.S. Prospectus or the Canadian Prospectus or in any other documents or arrangements. As used herein, the term "Underwriter" includes any person substituted for an Underwriter under this Section 10. SECTION 11. Agent for Service; Submission to Jurisdiction; Waiver of Immunities. By the execution and delivery of this Agreement, the Company (i) acknowledges that it has, by 35 separate written instrument, irrevocably designated and appointed CT Corporation System (or any successor) (together with any successor, the "Agent for Service"), as its registered agent upon which process may be served in any suit or proceeding arising out of or relating to this Agreement or the Securities, that may be instituted in any federal or state court in the State of New York, or brought under federal or state securities laws, and acknowledges that the Agent for Service has accepted such designation, (ii) submits to the non-exclusive jurisdiction of any such court in any such suit or proceeding, and (iii) agrees that service of process upon the Agent for Service (or any successor) and written notice of said service to the Company (mailed or delivered to its Chief Financial Officer at its principal office in Victoria, British Columbia, Canada), shall be deemed in every respect effective service of process upon the Company in any such suit or proceeding. The Company further agrees to take any and all action, including the execution and filing of any and all such documents and instruments, as may be necessary to continue such designation and appointment of the Agent for Service in full force and effect so long as any of the Securities shall be outstanding. To the extent that the Company has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, it hereby irrevocably waives such immunity in respect of its obligations under the above-referenced documents, to the extent permitted by law. SECTION 12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to the Representatives, c/o Merrill Lynch, Pierce, Fenner & Smith Incorporated at 4 World Financial Center, New York, New York 10080, attention of Bryan Giraudo; notices to the Company shall be directed to it at #1203, 4464 Markham Street, Victoria, British Columbia V8Z 7X8 Canada, Attention: Chief Financial Officer. SECTION 13. Parties. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Sub-underwriter, the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Sub-underwriter, the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters and the Sub-underwriter, the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter or the Sub-underwriter shall be deemed to be a successor by reason merely of such purchase. SECTION 14. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME. 36 SECTION 15. Effect of Headings. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. SECTION 16. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement. SECTION 17. Judgment Currency. In respect of any judgment or order given or made for any amount due hereunder that is expressed and paid in a currency (the "Judgment Currency") other than United States dollars, the Company will indemnify each Underwriter against any loss incurred by such Underwriter as a result of any variation as between (i) the rate of exchange at which the United States dollar amount is converted into the judgment currency for the purpose of such judgment or order and (ii) the rate of exchange at which an Underwriter is able to purchase United States dollars with the amount of judgment currency actually received by such Underwriter. The foregoing indemnity shall constitute a separate and independent obligation of the Company and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term "rate of exchange" shall include any premiums and costs of exchange payable in connection with the purchase of or conversion into United States dollars. 37 If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the Underwriters, the Sub-underwriter, the Company in accordance with its terms.

Merrill Lynch, Pierce, Fenner & Smith Incorporated, as Representative of the several Underwriters to be named in the within-mentioned Purchase Agreement c/o Merrill Lynch & Co. Merrill Lynch, Pierce, Fenner & Smith Incorporated 4 World Financial Center New York, New York 10080 Re: Proposed Public Offering by Aspreva Pharmaceuticals Corporation Dear Sirs: The undersigned, a shareholder and/or an option holder and/or an officer and/or director of Aspreva Pharmaceuticals Corporation, a corporation incorporated under the laws of Canada (the "Company"), understands that Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch") proposes to enter into a Purchase Agreement (the "Purchase Agreement") with the Company providing for the public offering of the Company's common shares ("Common Shares") (the Common Shares that will be issued in the public offering contemplated by the Purchase Agreement are herein referred to as the "Securities"). In recognition of the benefit that such an offering will confer upon the undersigned as a shareholder and/or an officer and/or director of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each underwriter to be named in the Purchase Agreement that, during a period of 180 days from the date of the Purchase Agreement (the "Lock-Up Period"), the undersigned will not, without the prior written consent of Merrill Lynch, directly or indirectly, (i) offer, pledge, sell (including any sale pursuant to Rule 144 under the Securities Act of 1933, as amended), contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any Common Shares (including, without limitation, Common Shares which may be deemed to be beneficially owned by such shareholder in accordance with the rules and regulations of the Securities and Exchange Commission or the securities legislation of any province or territory of Canada and Common Shares which may be issued upon exercise of any option or warrant) or any securities convertible into or exchangeable or exercisable for Common Shares, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition, or file, or cause to be filed, any registration statement or prospectus with respect to any of the foregoing (collectively, the "Lock-Up Securities") or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of Common Shares or other securities, in cash or otherwise. F-1 Notwithstanding the foregoing, if: (1) during the last 17 days of the Lock-Up Period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or (2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results or becomes aware that material news or a material event will occur during the 16 days immediately following the last day of the Lock-Up Period, the restrictions imposed by this letter shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, as applicable, unless Merrill Lynch waives, in writing, such extension, provided, however, that in no event shall the Lock-Up Period be extended beyond 214 days after the date of the Purchase Agreement. Notwithstanding the foregoing, and subject to the conditions below, the undersigned may transfer the Lock-Up Securities without the prior written consent of Merrill Lynch, provided that (1) Merrill Lynch receives a signed lock-up agreement for the balance of the Lock-Up Period from each donee, trustee, distributee, or transferee, as the case may be, (2) any such transfer shall not involve a disposition for value, (3) such transfers are not required to be reported in any public report or filing with the Securities Exchange Commission, or otherwise and (4) the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfers: (i) as a bona fide gift or gifts; or (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned; or (iii) as a distribution to limited partners, members or beneficiaries of the undersigned, as applicable, if the undersigned is a limited partnership, limited liability company or a trust, or to the estates of any such partners, members or beneficiaries; or (iv) to the undersigned's affiliates or stockholders if the undersigned is a corporation. Furthermore, the undersigned may sell Common Shares purchased by the undersigned on the open market following the public offering contemplated hereby if and only if (i) such sales are not required to be reported in any public report or filing with the Securities Exchange Commission, or otherwise and (ii) the undersigned does not otherwise voluntarily effect any public filing or report regarding such sales. The aggregate amount of Lock-Up Securities transferred by the undersigned pursuant to either of the two preceding paragraphs shall not exceed 200,000 Common Shares (such number of Common Shares to be proportionately adjusted upon the occurrence after the date of this Lock-Up Letter of any stock dividend, stock split or combination affecting the outstanding Common Shares). For purposes of this lock-up agreement, "immediate family" shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. The undersigned hereby acknowledges and agrees that written notice of any extension of the Lock-Up Period pursuant to the terms of this Lock-Up Letter will be delivered by Merrill Lynch to the Company (in accordance with Section 12 of the Purchase Agreement) and that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned F-2 further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this lock-up agreement during the period from the date of this lock-up agreement to and including the 34th day following the expiration of the Lock-Up Period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the Lock-Up Period (as may have been extended pursuant to the terms of the Lock-Up Letter) has expired. The undersigned agrees that it will not, without the prior written consent of Merrill Lynch, during the lock-up period, including any extension thereof, make any demand for, or exercise any right with respect to, the registration of any Common Shares or any securities convertible into or exchangeable or exercisable for Common Shares. The undersigned further agrees that the Company may, with respect to any Common Shares for which the undersigned is the record or beneficial holder, cause the transfer agent for the Company to note stop transfer instructions with respect to such Common Shares on the transfer books and records of the Company. The undersigned understands that the Company and the Underwriters will proceed with the public offering in reliance on this Lock-Up Letter. The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter and that, upon request, the undersigned will execute any additional documents necessary or desirable in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the successors and assigns of the undersigned. This Lock-Up Letter shall automatically terminate upon the earliest to occur, if any, of: (a) either Merrill Lynch on the one hand, or the Company, on the other hand, advising the other in writing, prior to the execution of the Purchase Agreement, that it has determined not to proceed with the public offering, (b) termination of the Purchase Agreement entered into between the Company and Merrill Lynch before the sale of the Securities, or (c) June 30, 2005, in the event that the registration statement related to the public offering has not been declared effective by that date.
