	(b)
	have

you are contracting hereunder, is based entirely upon the Information Record;

the case of the purchase by you of Purchased Securities as agent for an undisclosed principal, each beneficial purchaser of the Purchased Securities for whom you are acting is
purchasing as principal for its own account, and not for the benefit of any other person, a sufficient number of Purchased Securities so that each such purchaser has an aggregate acquisition cost for
such Purchased Securities of not less than $150,000 and you are an agent with proper authority to execute all documents required in connection with the purchase on behalf of the beneficial purchaser
(as prescribed by Section 2.10 of NI 45-106); or

	You
are an "accredited investor" (as defined in NI 45-106) by virtue of being a person, other than an individual or investment fund, that has net assets of at least

issuer"
at the time of any sale pursuant to Rule 904 of Regulation S, the certificate delivered to the buyer will, if required under the 1933 Act, bear the legend referred to above and

operate its properties, whether tangible or intangible, and to conduct its business or operations as currently conducted, except such

	There
is no action, proceeding or investigation (whether or not purportedly by or on behalf of the Corporation) pending or, to the best of the Corporation's knowledge, information and
belief, after due inquiry, threatened against or affecting the Corporation or any Subsidiary (including any predecessor companies) at law or in equity (whether in any court, arbitration or similar

Purchased Securities as fully paid and non-assessable Common Shares or any action taken or to be taken by the Corporation pursuant to or in connection with this Agreement.



	(s)
	The
execution and delivery of this Agreement, the performance and compliance with the terms of this Agreement and the issue and sale of the Purchased Securities by the Corporation

known to management by others, particularly during the period in which the financial statements are being prepared; (ii) designed such internal control over financial reporting, or caused it to

inquiry, to be pending, of the tax returns of the Corporation (whether federal, provincial, local or foreign) and to the best of the Corporation's knowledge, information and belief, after due inquiry,
there are no claims which have been or may be asserted relating to any such tax returns, which audits and claims, if determined adversely, would result in the assertion by any governmental agency of
any deficiency that would have a material adverse effect on the assets or properties, business, results of operations, prospects or condition (financial or otherwise) of the Corporation and the
Subsidiaries, taken as a whole.



	(hh)
	None
of Canada Revenue Agency or any provincial, state or foreign taxation authority has asserted or, to the best of the Corporation's knowledge, information and belief, after due
inquiry, threatened to assert any assessment, claim or liability for taxes due or to become due in connection with any review or examination of the tax returns of the Corporation filed for any year

observance or performance of any material term or material obligation to be performed by any of them under any agreements to which the Corporation or any of the Subsidiaries is a party or otherwise
bound and no event has occurred which with notice or lapse of time or both would constitute such a default, in any such case which default or event would have a material adverse effect on the assets
or properties, business, results of operations, prospects or condition (financial or otherwise) of the Corporation and the Subsidiaries, taken as a whole.



	(kk)
	This
Agreement and all other contracts and documentation required in connection with the issue and sale of the Purchased Securities shall be, prior to the Closing Date, duly
authorized, 



14







 


executed
and delivered by the Corporation, and each shall be a valid and binding obligation of the Corporation enforceable in accordance with its terms, except as the enforceability thereof may be
limited by (i) bankruptcy, insolvency, moratorium or similar laws affecting creditor's rights generally, (ii) general equitable principles, or (iii) limitations under applicable
law in respect of rights of indemnity, contribution and waiver of contribution.

defence thereof.



	(nn)
	The
Corporation and each of the Subsidiaries has its property and assets, whether owned or leased, and the conduct of its business insured by insurers of recognized financial
responsibility against loss or damage from insurable hazards or risks. Such insurance coverage is of a type and in such amounts as are reasonably adequate for the business in which the Corporation
operates as conducted by a reasonably prudent person, based on the advice of reputable insurance brokers consulted by the Corporation. In addition, the Corporation has obtained liability insurance for
all clinical trials conducted by or on behalf of or sponsored by the Corporation or in which the Corporation or its products or product candidates have participated in which human subjects were
participants. The Corporation has not made any material claim on any policy of insurance or been refused any insurance coverage sought or applied for. The Corporation does not have any reason to
believe that it or any Subsidiary will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to
continue its business at a cost that would not be reasonably expected to have a Material Adverse Effect.



	(oo)
	Except

Corporation or the Subsidiaries.

of the scientific activities of its business, including the experimentation, the conducting of scientific trials, studies or research or the use of substances or materials in such scientific

standing and the holders of the Health Permits are not in material default or breach thereof and no proceeding is pending or to the knowledge of the Corporation threatened to revoke or limit any
Health Permit except where such breach or default would not have a material adverse effect on the assets or properties, business, results of operations, prospects or condition (financial or otherwise)
of the Corporation and the Subsidiaries, taken as a whole;



	(iii)
	neither
the Corporation nor any of its Subsidiaries has used, except in compliance with all Health, Safety and Environmental Laws or except to the extent that the consequences would

distribute, use, treat, store, dispose of, transport or handle any Hazardous Substance or to carry out any Scientific Activities;



	(iv)
	neither
the Corporation nor any of its Subsidiaries has received any notice of, or been prosecuted for an offence alleging, non-compliance with any Health and
Environmental Laws, and neither the Corporation nor any of its Subsidiaries has settled any allegation of non-compliance short of prosecution except where such non-compliance
would not have a Material Adverse Effect. There are no orders or directions relating to environmental matters requiring any work, repairs, construction or capital expenditures to be made with respect
to any of the assets of the Corporation or any of the Subsidiaries nor has the Corporation or any of the Subsidiaries received notice of any of the same;

a federal, provincial, state, municipal or local clean-up site or corrective action under any Health, Safety and Environmental Laws except where such action would not have a material
adverse effect on the assets or properties, business, results of operations, prospects or condition (financial or otherwise) of the Corporation and the Subsidiaries, taken as a whole. Neither the
Corporation nor any of the Subsidiaries has received any request for information in connection with any federal, state, provincial, municipal or local inquiries as to disposal sites except where such

on the Stock Exchange.



	(d)
	Securities Filings: Forthwith after the Closing, the Corporation shall file such forms and documents as may be required under the
Securities Laws including, without limiting the foregoing (but subject to the Subscriber providing any necessary information), a Form D under Regulation D.



	(e)
	Performance of Acts: The Corporation shall perform and carry out all of the acts and things to be completed by it as provided in this
Agreement.



	(f)

	(h)
	PFIC Status:



	(i)
	The
Corporation will use its best efforts to prevent the Corporation from becoming a "passive foreign investment corporation" within the meaning of Section 1297 of the Code;
and



	(ii)
	upon
notice of the Subscriber, the Corporation will promptly provide to the Subscriber all tax, accounting and financial information and calculations requested in order for the
Subscriber to fulfill its United States tax reporting requirements under the Code in connection with owning shares in the Corporation. From and after the date hereof, the Corporation shall (and shall
cause each of its Subsidiaries), upon notice from the Subscriber, to (A) timely prepare and provide to the Subscriber information necessary for the Subscriber to fulfill such reporting
requirements, including, without limitation, preparing and providing such Corporation information returns, annual statements, consents and other information, calculated on a December 31 United
States tax year basis, required to be provided by the Corporation to the Subscriber under Subtitle A, Chapter IP, Part VI of the Code; and (B) cooperate in any tax audits, proceedings,
or contests related to the foregoing. The Corporation shall retain such independent advisors as may be necessary to assist with the foregoing and will bear the expenses associated with such
independent advisors. 







8.    Right of First Refusal    



	(a)
	Right of First Refusal. The Corporation shall not issue, sell or exchange, agree or obligate itself to issue, sell or exchange, or
reserve or set aside for issuance, sale or exchange, in a transaction not involving a public offering either in Canada or the United States, any (i) Common Shares, (ii) any other equity
security of the Corporation, including without limitation, preferred shares, (iii) any debt security of the Corporation (other than debt with no 



21







 


equity
feature) including without limitation, any debt security which by its terms is convertible into or exchangeable for any equity security of the Corporation, (iv) any security of the
Corporation that is a combination of debt and equity, or (v) any option, warrant or other right to subscribe for, purchase or otherwise acquire any such equity security or any such debt
security of the Corporation, unless in each case the Corporation shall have first offered to sell the portion of such securities which is required to be offered in accordance herewith (the
"Offered Securities") to the Subscriber and each other person or entity that has such a right (each an  "Offeree"and collectively, the "Offerees") as follows: Each Offeree shall have the right to purchase
(x) that portion of the Offered Securities as the number of Common Shares then held (including shares then issuable upon the exercise or conversion of outstanding exercisable or convertible
securities) by such Offeree bears to the total number of issued and outstanding Common Shares of the Corporation calculated on a fully diluted basis to include (i) the total number of Common
Shares subject to outstanding awards granted under stock plans of the Corporation and (ii) the total number of shares that could be issued upon the exercise or conversion of outstanding
securities (the "Basic Amount"), and (y) such additional portion of the Offered Securities as such Offeree shall indicate it will purchase if the
other Offerees subscribe for less than their Basic Amounts (the "Undersubscription Amount"), at a price and on such other terms as shall have been
specified by the Corporation in writing delivered to such Offeree (the "Offer"), which Offer by its terms shall remain open and irrevocable for a period
of 20 days from receipt of the offer. The foregoing right of first refusal shall be subject to the right of first refusal granted to Laurus Master Fund, Ltd. ("Laurus") relating to
certain debt and convertible securities of the Corporation pursuant to a securities purchase agreement dated as of April 22, 2005 between the Corporation and Laurus; provided, however, that if
Laurus at any time does not exercise, in whole or in part, its rights of first refusal in respect of an Additional Financing (as defined in such agreement), the Offeree shall have the right to
participate in such Additional Financing (to the extent that such Additional Financing relates to the sale and issuance of securities convertible or exchangeable into Common Shares of the Corporation)
and the securities with respect to which Laurus has not exercised its right of first refusal shall constitute Offered Securities for purposes hereof. 



	(b)
	Notice of Acceptance. Notice of each Offeree's intention to accept, in whole or in part, any Offer made shall be evidenced by a written
notice signed by such Offeree and delivered to the Corporation prior to the end of the 20-day period of such offer, setting forth such of the Offeree's Basic Amount as such Offeree elects
to purchase and, if such Offeree shall elect to purchase all of its Basic Amount, such Undersubscription Amount as such Offeree shall elect to purchase (the "Notice of
Acceptance"). If the Basic Amounts subscribed for by all Offerees are less than the total Offered Securities, then each Offeree who has set forth Undersubscription Amounts in
its Notice of Acceptance shall be entitled to purchase, in addition to the Basic Amounts subscribed for, all Undersubscription Amounts it has subscribed for; provided, however, that if the
Undersubscription Amounts subscribed for exceed the difference between the Offered Securities and the Basic Amounts subscribed for (the "Available Undersubscription
Amount"), each Offeree who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the
Undersubscription Amount subscribed for by such Offeree bears to the total Undersubscription Amounts subscribed for by all Offerees, subject to rounding by the Board of Directors to the extent it
reasonably deems necessary. The purchase by the Offerees of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Corporation and the Offerees of a purchase
agreement relating to such Offered Securities reasonably satisfactory in form and substance to the Corporation and the Offerees and their respective counsel. 



22













  



	(c)
	Conditions to Acceptances and Purchase.



	(i)
	Permitted Sales of Refused Securities. If Notices of Acceptance are not given by the Offerees in respect of all the Offered Securities,
the Corporation shall have 90 days from the expiration of the period set forth above to close the sale of all or any part of such Offered Securities as to which a Notice of Acceptance has not
been given by the Offerees (the "Refused Securities") to the Person or Persons specified in the Offer, but only for cash and otherwise in all respects
upon terms and conditions, including, without limitation, unit price and interest rates, which are no more favourable, in the aggregate, to such other person or persons or less favourable to the
Corporation than those set forth in the Offer.



	(ii)
	Reduction in Amount of Offered Securities. If the Corporation proposes to sell less than all the Refused Securities (any such sale to
be in the manner and on the terms specified above), then each Offeree may, at its sole option and in its sole discretion, reduce the number of, or other units of the Offered Securities specified in
its respective Notices of Acceptance to an amount which shall be not less than the amount of the Offered Securities which the Offeree elected to purchase pursuant to (b) above multiplied by a
fraction, (i) the numerator of which shall be the amount of Offered Securities which the Corporation actually proposes to sell, and (ii) the denominator of which shall be the amount of
all Offered Securities the Corporation proposed to sell in the notice of the Offer delivered pursuant to paragraph (a) above. If any Offeree so elects to reduce the number or amount of Offered
Securities specified in its Notice of Acceptance, the Corporation may not sell or otherwise dispose of more than the reduced amount of the Offered Securities until such securities have again been
offered to the Offerees in accordance with (a) above.



	(iii)
	Closing. Upon the closing, which shall include full payment to the Corporation, of the sale to such other Person or Persons of all or
less than all the Refused Securities, the Offerees shall purchase from the Corporation, and the Corporation shall sell to the Offerees, the number of Offered Securities specified in the Notices of
Acceptance, as reduced pursuant to paragraph (b) above if the Offerees have so elected, upon the terms and conditions specified in the Offer.






	(d)
	Further Sale. In each case, any Offered Securities not purchased by the Offerees or other person or persons in accordance with
paragraph (c)(iii) above may not be sold or otherwise disposed of until they are again offered to the Offerees under the procedures specified in
paragraph (c)(i)-(iii) above.



	(e)
	Exceptions. The rights of the Subscriber under this Section 8 shall not apply to:



	(i)
	Common

	(ii)
	any
capital stock or derivative thereof granted to an employee, director or consultant under a stock plan approved by the Board of Directors of the Corporation and its shareholders,



	(iii)
	any
securities issued as consideration for the acquisition of another entity by the Corporation by merger or share exchange (whereby the Corporation owns no less than 51% of the
voting power of the surviving entity) or purchase of substantially all of such entity's stock or assets, if such acquisition is approved by the Board of Directors, including a majority of the
independent directors eligible to vote thereon, 






23







 


	(iv)
	any
securities issued in connection with a strategic partnership, joint venture or other similar agreement, provided that the purpose of such arrangement is not primarily the raising
of capital and that such arrangement is approved by the Board of Directors, including a majority of the independent directors eligible to vote thereon,



	(v)
	any
securities issued to a financial institution in connection with a bank loan or lease with such financial institution provided that such is approved by the Board of Directors,
including a majority of the independent directors,



	(vi)
	securities
issuable upon the exercise or conversion of convertible or exercisable securities outstanding on the Closing Date, as amended as contemplated by this Agreement.






	(f)
	Termination. The rights of the Subscriber under this Section 8 shall terminate and shall be of no further force and effect from
and after the date upon which the number of Common Shares owned, directly or indirectly, by the Subscriber, together with (i) any venture capital fund that, directly or indirectly, controls, is
controlled by, or is under common control with the Subscriber (including without limitation any venture capital fund now or hereafter existing that is controlled by or under common control with one or
more general partners or managing members of, or shares the same management company with, the Subscriber) or (ii) any of the general partners, managing member or management companies noted in
clause (i), constitutes less than 5% of the total number of Common Shares issued and outstanding on such date.

representations, warranties and covenants of the Corporation herein are made with the intent that they be relied upon by the Subscriber in determining the suitability of the
Purchased Securities for investment. The Corporation hereby agrees to indemnify the Subscriber against any and all losses (other than loss of profits), claims, costs, expenses and damages or
liabilities whatsoever (collectively, the "Losses") which it may suffer or incur arising out of or based upon any representation or warranty of the
Corporation contained herein being untrue or any breach or failure by the Corporation to comply with any covenant or agreement made by the Corporation herein, provided that the Corporation shall not
be required to indemnify or save harmless the Subscriber in respect of any Losses unless the Subscriber shall have provided notice to the Corporation in accordance with Section 11(e) on or
prior to the date that is one year from the Closing Date. 


10.    Exclusivity    



        The
Purchased Securities form part of a larger private placement of 13,996,466 Common Shares (the "Private Placement") which are being
purchased equally by the Subscriber and one other subscriber pursuant to substantially similar subscription agreements. The Corporation covenants and agrees with the Subscriber that, until the earlier
of (i) the Closing and (ii) the termination of this Agreement, neither the Corporation nor any of its directors, officers or agents will, directly or indirectly (a) solicit,
