For the purposes of this Section 8.1, each Series A Investor shall be deemed to be a Shareholder and to own a number of Series A Preferred Shares equal to the proportion of the Series A Preferred Shares held by Aspreva Funding that corresponds to such Series A Investor's proportionate equity ownership interest in Aspreva Funding. 8.2 TERMINATION EVENTS This Agreement shall terminate, except as provided in Section 8.3, if: (a) the Corporation and Shareholders owning not less than 75% of the Common Shares (on a Fully Converted Basis) that are subject to this Agreement so agree (for the purposes of this paragraph (a), each Series A Investor shall be deemed to be a Shareholder and to own a number of Series A Preferred Shares equal to the proportion of the Series A Preferred Shares held by Aspreva Funding that corresponds to such Series A Investor's proportionate equity ownership interest in Aspreva Funding); (b) the Corporation is dissolved, liquidated or formally wound-up; (c) one Shareholder acquires all Shares; (d) a duly approved Initial Public Offering is completed on a Senior Stock Exchange. 8.3 SURVIVING OBLIGATIONS The termination of this Agreement shall not affect the right of any party to whom money is owed hereunder at the time of termination to receive that money according to the provisions hereof or affect any other rights or obligations which arose hereunder in respect of matters occurring prior to such termination. -37- 8.4 DETERMINATION Subject to Section 8.3 and on-going obligations (if any) under Subsection 7.2(a)(ii), this Agreement shall terminate in respect of any party who ceases for any reason to be a Shareholder, and the Agreement shall remain in full force and effect with respect to the remaining Shareholders. For the purposes of this Section 8.4, each Series A Investor shall be deemed to be a Shareholder and to own a number of Series A Preferred Shares equal to the proportion of the Series A Preferred Shares held by Aspreva Funding that corresponds to such Series A Investor's proportionate equity ownership interest in Aspreva Funding. 9. REPRESENTATIONS, WARRANTIES AND COVENANTS OF SHAREHOLDERS 9.1 REPRESENTATIONS, WARRANTIES AND COVENANTS Each Shareholder (except, with respect to paragraphs (b) and (d), for agreements and arrangements previously disclosed to the Corporation by Aspreva Funding) hereby, separately and severally and with respect to itself and its own Shares only, represents and warrants to each other Shareholder and to the Corporation that as of the date of this Agreement it: (a) is acquiring and shall hold its Shares as sole principal and for investment purposes only, and not with a view to the distribution thereof and not in trust for or on behalf of any other person or persons; (b) is neither a party to or bound by any other agreement regarding the ownership of its Shares; (c) is not a party to, bound by or subject to any indenture, mortgage, lease, agreement, instrument, charter, Articles, by-laws or constating documents, order, judgment, decree, or, to the best knowledge of the Shareholder law, statute or regulation which would be violated, contravened, or breached by, or under which any default would occur as a result of, the execution and delivery by such Shareholder of this Agreement or the performance by such Shareholder of any of the terms hereof; (d) has not created any mortgage, lien or encumbrance or security interest upon any of its Shares, and is not subject to or bound by any agreement under which any mortgage, encumbrance, lien or security interest may be created upon any of its Shares; (e) if a corporation or a partnership, that it was duly incorporated, formed or created, as applicable and is validly existing under the laws of its jurisdiction of incorporation, formation or creation, as applicable, and that it has the corporate or legal power and capacity to own its assets and to enter into and perform its obligations pursuant to this Agreement; (f) the TW Investor hereby represents and warrants (the "TW Representation") that none of its direct partners is a natural person that is a citizen or resident of the United States for United States federal income tax purposes, and pursuant to the provisions of the limited partnership agreement of the TW Investor, upon the liquidation of the TW Investor, its general partner is entitled to retain aggregate distributions with respect to its investment in the Corporation (in addition to any distributions received by the general partner in connection with its contribution to the TW Investor) not in excess of 20% of the excess of all distributions made by the TW Investor with respect to its investment in the -38- Corporation over all contributions to the TW Investor with respect to its investment in the Corporation, plus (in certain circumstances) distributions approximately equal to $1.5 million. The TW Investor covenants and agrees that if at any time after the date hereof the TW Investor becomes aware of any fact, event, development, occurrence or circumstance that either individually or in the aggregate is reasonably likely to result in the TW Representation becoming untrue in any respect (as if the TW Representation were made as of such date), such TW Investor shall (i) give prompt written notice thereof to the Corporation and to Sprout Capital IX, L.P. and (ii) cooperate with the other US Investors and use all commercially reasonable efforts to prevent the ownership (including an indirect ownership and an ownership by attribution) of the Corporation (or any of its subsidiaries) by United States persons as defined in the United States Internal Revenue Code of 1986, as amended from exceeding 49% of the total outstanding Common Shares (assuming conversion of all outstanding Preferred Shares or other convertible securities) of the Corporation (or equivalent securities of any of its subsidiaries); (g) the HBM Investor hereby represents and warrants (the "HBM Representation") that (i) it is 100% indirectly owned by HBM BioVentures Ltd., a Swiss corporation (the "Swiss Parent"), which is widely held, and (ii) if any shares of Swiss Parent are owned by an individual that is a citizen or resident of the United States for federal income tax purposes, such ownership, if any, shall not exceed 1% of the total outstanding shares of Swiss Parent. The HBM Investor covenants and agrees that if at any time after the date hereof the HBM Investor becomes aware of any fact, event, development, occurrence or circumstance that either individually or in the aggregate is reasonably likely to result in the HBM Representation becoming untrue in any respect (as if the HBM Representation were made as of such date), the HBM Investor shall (i) give prompt written notice thereof to the Corporation and to Sprout Capital IX, L.P. and (ii) cooperate with the other US Investors and use all commercially reasonable efforts to prevent the ownership (including an indirect ownership and an ownership by attribution) of the Corporation (or any of its subsidiaries) by United States persons as defined in the United States Internal Revenue Code of 1986, as amended from exceeding 49% of the total outstanding Common Shares (assuming conversion of all outstanding Preferred Shares or other convertible securities) of the Corporation (or equivalent securities of any of its subsidiaries). 10. CONFIDENTIALITY 10.1 DEFINITION OF CONFIDENTIAL INFORMATION For the purposes of this Agreement, "Confidential Information" means: (a) all information, knowledge, or data pertaining to the business and affairs of the Corporation or of its Subsidiaries including, without limitation, financial information, marketing, manufacturing and commercial strategies, the terms and conditions of any contracts or agreements, (including this Agreement), actual or prospective business relationships to the extent not publicly disclosed; (b) all information, knowledge or data of an intellectual, technical, scientific or industrial nature in which the Corporation or its Subsidiaries has a proprietary or ownership interest or has a legal duty to protect, including, without limitation, laboratory procedures and techniques, biochemical strategies and know-how, technical data, drawings, photographs, specifications, standards, manuals, reports, formulas, compilations, formulations, compositions, compounds, processes, information, lists, research data, trade secrets, -39- biochemical and other scientific strategies and concepts, inventions, designs, know-how, methods and technical information, whether furnished or prepared before or after the date of this Agreement; (c) all copies and tangible embodiments of the foregoing, in whatever form or medium; and (d) that is commercially valuable and not generally known. Notwithstanding the foregoing, Confidential Information shall not include the U.S. tax treatment and the U.S. tax structure of the transaction contemplated by this Agreement. 10.2 OBLIGATION OF CONFIDENTIALITY No Shareholder shall disclose any Confidential Information to any Person who is not a Shareholder at the time of disclosure at any time while it is a Shareholder or at any time thereafter. The foregoing obligations of confidentiality shall not apply to Confidential Information that: (a) is in the public domain other than through a breach of this Section; (b) is or was obtained from sources other than the Corporation or a Subsidiary without breach of any duty of confidentiality; (c) is required to be disclosed pursuant to applicable laws, or policies. or regulations of any regulatory authority; (d) is disclosed in any legal proceeding to which the Shareholder, the Shareholder's Director nominees and Observers, if any, is a party under this Agreement; (e) is disclosed with the permission of the Corporation; (f) is disclosed to the directors, officers, employees, managers, professional advisers and consultants of a Shareholder on a need to know basis; or (g) is disclosed pursuant to Section 10.3. 10.3 PERMITTED DISCLOSURES FOR DIRECTORS AND OFFICERS Notwithstanding Section 10.2, either a Director who is an Investor Nominee pursuant to Section 3.1 or a Shareholder whose nominee is a Director or officer of the Corporation or any Subsidiary may disclose to any Person who is not a Shareholder at the time of disclosure such Confidential Information as is consistent with the promotion or advancement of the Corporation or Subsidiary, provided that such disclosure: (a) is made on a strictly confidential basis; and (b) is consistent with the fiduciary, statutory and contractual duties of the Director or the Shareholder in its capacity as a director or officer of the Corporation or the Subsidiary. -40- 10.4 OBLIGATIONS SURVIVE The obligations and rights of the Shareholders under this Article 10 shall survive any termination of this Agreement and shall continue even after a Shareholder shall have transferred or disposed of all of its Shares or shall otherwise cease to be a Shareholder. 10.5 REMEDIES In the event that any Shareholder uses, discloses, divulges or communicates to any Person any Confidential Information in breach of this Article 10 or otherwise breaches any provision of this Article 10, or if the Corporation has reasonable grounds for believing a Shareholder may use, disclose, divulge or communicate to any Person any Confidential Information in breach of this Article 10 or otherwise breach any provision of this Article 10, then the Corporation shall be entitled, in addition to other remedies and damages available, to seek an interlocutory and permanent injunction whereby the Shareholder shall be ordered to respect and comply with the covenants and agreements contained in this Agreement. 11. TAX (a) No party hereto shall, and the Corporation shall not permit the shareholders of the Corporation to, without the prior written consent of either Sprout Capital IX, L.P. or InterWest Partners VIII, L.P. (each an "Appointed Investor"), directly or indirectly issue or transfer stock (including options, warrants or similar rights to acquire stock and convertible notes) in the Corporation (or any of its subsidiaries) to any investor (1) if such issuance or transfer would result in an increase in the ownership (including an indirect ownership and an ownership by attribution) of the Corporation (or any of its subsidiaries) by United States persons as defined in the United States Internal Revenue Code of 1986, as amended (the "Code") so as to cause such ownership to exceed the greater of (i) 40% of the total outstanding Common Shares (assuming conversion of all outstanding Preferred Shares or other convertible securities) of the Corporation (or equivalent securities of any of its subsidiaries) and (ii) such percentage as exists on the date of such issuance or transfer, or (2) if, in the reasonable determination of counsel or accountants for an Appointed Investor, such issuance or transfer would cause the Corporation (or any of its subsidiaries) to be a "Controlled Foreign Corporation" or a "Foreign Personal Holding Company" (each as defined in the Code); provided, however, that the foregoing obligation shall not apply to the TW Investor if at any time after the date hereof there exists any fact, event, development, occurrence or circumstance that either individually or in the aggregate is reasonably likely to result in the TW Representation becoming untrue in any respect (as if the TW Representation were made as of such date), and the TW Investor complies with its obligations under Section 9.1(f) hereof; provided, further that the foregoing obligation shall not apply to the HBM Investor if at any time after the date hereof there exists any fact, event, development, occurrence or circumstance that either individually or in the aggregate is reasonably likely to result in the HBM Representation becoming untrue in any respect (as if the HBM Representation were made as of such date), and the HBM Investor complies with its obligations under Section 9.1(g) hereof. No later than two (2) months following the end of each Corporation taxable year, the Corporation shall provide the following information to the US Investors: (i) the Corporation's (and, if different, its subsidiaries') capitalization table as of the end of the last day of such taxable year and (ii) a report regarding the Corporation's (and, if different, its subsidiaries') status as a Controlled Foreign Corporation or a Foreign Personal Holding Company; provided, however that unless the Corporation receives any information from any US Investor regarding any change in its ownership in the Corporation or its own ownership structure, in preparing a report described in (ii), the Corporation shall assume that the US Investor's ownership in the Corporation is the same as the ownership as of the date of the Closing. In addition, the Corporation shall provide the US -41- Investors with access to such other information as may be reasonably required by such US Investors to determine the Corporation's (and its subsidiary's) status as a Controlled Foreign Corporation or a Foreign Personal Holding Company to determine whether each such US Investor is required to report its pro rata portion of the Corporation's (or its subsidiaries') "Subpart F income" (as defined in Section 952 of the Code) on its United States federal income tax return, and to allow such US Investors to otherwise comply with applicable Untied States federal income tax laws. (b) In the event that counsel or accountants for an Appointed Investor reasonably determines that there is a significant risk either that the Corporation (or any of its subsidiaries) is a Controlled Foreign Corporation or that the Corporation has met or shall meet the stock ownership requirement under Section 552(a)(2) (the "Foreign Personal Holding Company Ownership Test") (or any successor thereto) at any time, the Corporation shall (and shall cause such subsidiary to) use all commercially reasonable efforts to avoid generating (i) for any taxable year in which the Corporation (or such subsidiary) is a Controlled Foreign Corporation (or in which there is such risk), Subpart F income, and (ii) for any taxable year in which the Corporation (or such subsidiary) has met (or shall meet) the Foreign Personal Holding Company Ownership Test (or in which there is such risk), "Foreign Personal Holding Company Income," as such term is defined in Section 553 of the Code. Without limiting the generality of the foregoing, unless and until counsel or accountants for an Appointed Investor reasonably determines that there is no risk that the Corporation (or any of its subsidiaries) would meet the Foreign Personal Holding Company Ownership Test, the Corporation shall not (and shall cause its subsidiaries not to) enter into a transaction or take an action or inaction (including, without limitation, dividend distributions and making or maintaining inter-company loans) that may cause the Corporation or any of its subsidiaries to earn any Foreign Personal Holding Company Income (including dividends, interest, rents and royalties), unless there is no risk that such income would, directly or indirectly, cause the Corporation or the subsidiary, as the case may be, to meet the gross income requirement under Section 522(a)(1) of the Code. In the event that the Corporation (or any of its subsidiaries) is reasonably determined by counsel or accountants for an Appointed Investor to be either a Controlled Foreign Corporation or a Foreign Personal Holding Company (or any successor thereto) with respect to the securities held by any US Investor, the Corporation agrees, to the extent permitted by law, to annually make dividend distributions to each US Investor (including to any intermediary entity through which any US Investor holds securities in the Corporation) in an amount equal to 50% of any income deemed distributed to such US Investor pursuant to the foregoing provisions, unless such distributions are explicitly waived by US Investors holding, directly or indirectly, a majority of the outstanding Common Shares (assuming conversion of all outstanding Preferred Shares or other convertible securities) then held by all US Investors. (c) The Corporation shall (and shall cause each of its subsidiaries to) use all commercially reasonable efforts to avoid being a "Passive Foreign Investment Company" within the meaning of Section 1297 of the Code (or any successor thereto). No later than two (2) months following the end of each Corporation taxable year, the Corporation shall provide a report regarding the Corporation's (and, each of its subsidiaries') status as a Passive Foreign Investment Company. If a "Qualified Electing Fund" election is made by any US Investor pursuant to Section 1295 of the Code (or any successor thereto) with respect to the Corporation or any of its subsidiaries, the Corporation shall provide annual financial information to the US Investor in the form attached hereto as Schedule E and shall provide the US Investor with reasonable access to such other information as may be reasonably required for purposes of filing U.S. federal income tax returns in connection with such Qualified Electing Fund election. In the event that a US Investor that has made a Qualified Electing Fund election must include in its gross income for a particular taxable year its pro rata share of the Corporation's (or any of its subsidiaries') earnings and profits pursuant to Section -42- 1293 of the Code (or any successor thereto), the Corporation agrees to make a dividend distribution to such US Investor (no later than 90 days following the end of the Investor's taxable year) in an amount equal to 50% of the amount so included by the US Investor, unless such distribution is explicitly waived by such US Investor. (d) Without limiting any of the foregoing, during the taxable year ending on December 31, 2004, the Corporation shall (and shall cause each of its subsidiaries to) use all commercially reasonable efforts to manage its operations and activities (including inter-company distributions and payments) so as not to create any net positive earnings and profits (computed for purposes of Section 1293 of the Code assuming for this purpose a Qualified Electing Fund election is made) or any net positive "undistributed foreign personal holding company income" (as defined in Section 556 of the Code, assuming for this purpose the Corporation is a Foreign Personal Holding Company). 12. GENERAL PROVISIONS 12.1 NO PARTNERSHIP Nothing in this Agreement or in the relationship of the parties hereto shall be construed as in any sense creating a partnership among or between the parties or as giving to any party any of the rights or subjecting any party to any of the creditors of the other party. 12.2 TIME OF THE ESSENCE Time shall be of the essence of this Agreement. 12.3 FURTHER ACTS Each of the parties to this Agreement shall at the request of any other party, and at the expense of the Corporation, execute and deliver any further documents and do all acts and things as that party may reasonably require in order to carry out the true intent and meaning of this Agreement. 12.4 PARTIES OF INTEREST This Agreement and the rights of such party hereunder shall enure to the benefit of and be binding upon the parties hereto, their permitted assigns and their personal representatives, administrators, heirs and successors. 12.5 SHARE REORGANIZATIONS The provisions of this Agreement relating to Shares shall also apply, with the necessary changes, to the following: (a) any Shares or securities into which such Shares may be converted, changed, reclassified, redivided, redesignated, redeemed, subdivided or consolidated; (b) any Shares or securities that are received by the shareholders of the Corporation as a stock dividend or distribution payable in Shares or securities of the Corporation; and (c) any Shares or securities of the Corporation or of any successor or continuing corporation to the Corporation that may be received by the shareholders of the Corporation on a reorganization, amalgamation, consolidation or merger or otherwise. -43- 12.6 GOVERNING LAW This Agreement shall be exclusively construed and governed by the laws in force in British Columbia without regard to its conflicts of laws principles and the laws of Canada applicable thereto and the courts of British Columbia (and the Supreme Court of Canada, if necessary) shall have exclusive jurisdiction to hear and determine all disputes arising hereunder.

(2) Please check here if 75% or more of the Corporation's gross income constitutes passive income. [ ]. Please check here if 75% or more of any of the subsidiaries gross income constitutes passive income, and specify such subsidiary. [ ] Passive Income: For purposes of this test, passive income includes: - Dividends, interests, royalties, rents and annuities, excluding, however, rents and royalties which are received from an unrelated party in connection with the active conduct of a trade or business. - Net gains from the sale or exchange of property -- - which gives rise to dividends, interest, rents or annuities (excluding, however, property used in the conduct of a banking finance or similar business, or in the conduct of an insurance business); - which is an interest in a trust, partnership, or REMIC; or - which does not five rise to income. - Net gains from transactions in commodities. - Net foreign currency gains. - Any income equivalent to interest. Look-through rule: if the Corporation owns, directly or indirectly, 25% of the stock by value of another corporation, the Corporation must take into account its proportionate share of the income received by such other corporation. The revenue received pursuant to the CellCept Collaboration and Promotion Agreement, among Aspreva Pharmaceuticals GmbH, Hoffmann-La Roche Inc. and F. Hoffman-La Roche Ltd. is not deemed to constitute passive income. (3) Please check here if the average fair market value during the taxable year of passive assets held by the Corporation (or any of its subsidiaries) equals 50% or more of the average fair market value of all of the Corporation's assets. [ ] Note: This test is applied on a gross basis; no liabilities are taken into account. Passive Assets: For purposes of this test, "passive assets" are those assets which generate (or are reasonably expected to generate) passive income (as defined above). Assets which generate partly passive and partly non-passive income are considered passive assets to the extent of the relative proportion of passive income (compared to non-passive income) generated in a particular taxable year by such assets. Please note the following: - A trade or service receivable is non-passive if it results from sales or services provided in the ordinary course of business. -2- - Intangible assets that produce identifiable items of income, such as patents or licenses, are characterized in terms of the type of income produced. - Goodwill and going concern value must be identified to a specific income producing activity and are characterized in accordance with the nature of that activity. - Cash and other assets easily convertible into cash are passive assets, even when used as working capital. - Stock and securities (including tax-exempt securities) are passive assets, unless held by a dealer as inventory. Average Value: For purposes of this test, "average fair market value" equals the average quarterly fair market value of the assets for the relevant taxable year. Look-through rule: if the Corporation owns, directly or indirectly, 25% of the stock by value of another corporation, the Corporation must take into account its proportionate share of the passive assets of such other corporation.
