further approval or authorization of any shareholder, the Board of Directors of
the Company or others is required for the issuance and sale of the Purchased

received a valid extension of such time of filing or submission and has filed or
submitted any such Continuous Disclosure Reports prior to the expiration of any
such extension, except where a failure to do so could not have or reasonably be

Continuous Disclosure Reports complied with the requirements of the Securities
Laws, and none of the Continuous Disclosure Reports, when filed or submitted,
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The financial statements of the Company included in the Continuous

|(r) | Securities Laws; Internal Accounting Controls.  The Company is in material compliance with all provisions of the Securities Laws which are applicable to it.  The Company and the Subsidiaries maintain a system of internal accounting controls as required by MI 52-109. The Company has established disclosure controls and procedures as required by MI 52-109 for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company, including its Subsidiaries, is made known to the certifying officers by others within those entities, particularly during the period in which the Companys most recently filed periodic report under the Securities Laws, as the case may be, is being prepared.  The Companys certifying officers have evaluated the
effectiveness of the Companys controls and procedures as of the date prior to the filing date of the most recently filed periodic report under the Securities Laws (such date, the Evaluation Date).  The Company presented in its most recently filed periodic report under the Securities Laws the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date to the extent required by MI 52-109.  Since the Evaluation Date, except as disclosed in the Continuous Disclosure Reports, there have been no significant changes in the Companys internal disclosure controls and procedures or its internal control over financial reporting (as such terms are defined in Section 1.1 of MI 52-109) or, to the Companys knowledge, in other factors that could significantly affect the Companys internal disclosure controls and procedures
or its internal control over financial reporting.  To the extent any requirements applicable to the Company under the Sarbanes-Oxley Act of 2002, and the rules and regulations promulgated by the SEC pursuant to such Act, differ from the foregoing, the Company is in compliance with all such requirements, except as would not have a Material Adverse Effect.

(or obtain extensions in respect thereof and file or submit within the
applicable grace period) all reports required to be filed or submitted by the
Company after the date of this Agreement pursuant to Securities Laws, when
applicable except where a failure to so timely file or submit could not have or
reasonably be expected to have a Material Adverse Effect. As long as the
Purchaser owns Purchased Shares, if the Company is not required to file reports
pursuant to the Exchange Act, it shall prepare and furnish to the Purchaser and

reasonably, all to the extent required
from time to time to enable such Person to sell such Purchased Shares without
registration under the United States Securities Act in accordance with the
exemptions provided by Rule 144.

5.4Securities Laws Disclosure; Publicity.  The Company shall issue a press release, file a material change report and, if applicable, submit a Current Report on Form 6-K pursuant to Securities Laws and within the timeframes set out in the Securities Laws, reasonably acceptable to the Purchaser disclosing the material terms of the transactions contemplated hereby or such other information as may be required by applicable Securities Laws, and shall attach and/or file or submit those Transaction Documents required to be filed or submitted with any such filings or submissions by the applicable Securities Laws or required to be filed on SEDAR.  The Company and the Purchaser shall consult with each other in issuing such press release,
submitting any such Form 6-K and filing such Transaction Documents on SEDAR as required by Securities Laws, and any other press releases with respect to the transactions contemplated by the Transaction Documents. Neither the Company nor the Purchaser shall issue any such press release or otherwise make any such public statement or publicly disclose (collectively, a Public Disclosure) without the prior consent of the Company, with respect to any Public Disclosure of the Purchaser, or without the prior consent of the Purchaser, with respect to any Public Disclosure of the Company, which consent shall not unreasonably be withheld.  Notwithstanding the foregoing, in the event that the Company or the Purchaser is required by Applicable Laws or, in the case of the Company the requirements of any Trading Market on which its Common Shares are listed, to publicly disclose information regarding the transactions contemplated by the
Transaction Documents (a Required Disclosure) and it is not then reasonably possible to delay such Required Disclosure until such time as such Party shall have notified, consulted with and obtained the consent of the other Party to such Required Disclosure as required by thisSection 5.4, then any such Required Disclosure made without prior notice to, consultation with or obtaining the consent of the Purchaser shall not be deemed a breach of the disclosing Partys obligations under thisSection 5.4.

5.5Regulation S; Directed Selling Efforts.  (i) None of the Company, its Subsidiaries or any persons acting on its or their behalf shall engage in any directed selling effort (within the meaning of Regulation S) with respect to the Purchased Shares; (ii) to the extent that the Company engages in a sale of the Purchased Shares, or other securities substantially similar to the Purchased Shares, outside of the United States, it shall comply with the requirements for an offshore transaction, as such term is defined in Regulation S; (iii) none of the Company, its Subsidiaries or any Person acting on its or their behalf shall offer to sell any of the Purchased Shares by means of any form of general solicitation or general
advertising (as those terms are used in Regulation D of the United States Securities Act) or in any manner involving a public offering within the meaning of Section 4(2) of the United States Securities Act; and (iv) the Company shall notify its transfer agent as soon as practicable upon it becoming a domestic issuer, as defined in Regulation S.

5.6Use of Proceeds. The Company shall use the net
proceeds from the sale of the Purchased Shares hereunder for the purposes and in
the amounts specified inSection 5.6 of the Disclosure
Letterfor so long as such purposes are scientifically
and economically feasible, as determined by management of the Company and its
board of directors, and not for the satisfaction of any portion of the
Debentures or any debt (other than debt which may be incurred

- 23 -

in implementing
the purposes specified inSection 5.6 of the Disclosure
Letter) or to redeem any Common Shares or Common Share
Equivalents or to settle any outstanding litigation.

5.7
        Indemnification.(a)
        Indemnification of Purchaser.  Subject to the provisions of thisSection 5.7(a), the Company shall indemnify and hold the Purchaser and its directors, officers, partners and employees (each, a Purchaser Party) harmless from any and all claims, legal procedures, obligations, liabilities, contingencies, damages, losses, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys fees and costs of investigation that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction
Documents or (b) any action instituted against the Purchaser, by any shareholder of the Company, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is based upon a breach of the Purchasers representations, warranties or covenants under the Transaction Documents or any relevant and material agreements or understandings the Purchaser may have with any such shareholder or any material violations by the Purchaser of Securities Laws or any conduct by the Purchaser which constitutes fraud, gross negligence or wilful misconduct).  If any action shall be brought against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defence thereof with counsel of its own choosing.  Any Purchaser Party shall have the right to employ separate counsel in any such action and participate in the
defence thereof, but the fees and expenses of such counsel shall be at the expense of such Purchaser Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defence and to employ counsel or (iii) in such action there is, in the reasonable opinion of such separate counsel, a material conflict on any material issue between the position of the Company and the position of such Purchaser Party.  The Company shall not be liable to any Purchaser Party under this Agreement for any settlement by a Purchaser Party effected without the Companys prior written consent, which shall not be unreasonably withheld or delayed.  For avoidance of doubt, the Companys obligations and the Purchasers rights underSection 5.7(a)are in addition to any such obligations and rights imposed or provided in the
Registration Rights Agreement relating to the registration of Purchased Shares.(b)
        Limitation.
To the extent permitted by Applicable Laws, the liability of the Company underSection 5.7(a)shall be limited
to the Purchase Price.
 - 24 -

5.8Subsequent Equity Sales. Neither the Company nor
any Subsidiary shall, until July 31, 2007, issue Common Shares or Common Share
Equivalents at a price per share that is less than the Per Share Purchase Price,
except for Exempt Issuances.


5.9
        Board Representation.(a)
        Commencing with the first of the annual, special or extraordinary meetings of shareholders of the Company the record date for which next follows the Closing Date, and at each annual meeting of shareholders of the Company thereafter, the Purchaser shall be entitled to present to the Board of Directors or the nominating committee thereof one nominee (each such person, or replacement designated by the Purchaser, a Purchaser Nominee) for election to the Board of Directors at each such meeting of shareholders of the Company.  In the event of the death, disability, resignation or removal of a Purchaser Nominee, or the failure of a Purchaser Nominee to qualify to act as a director pursuant toSection 5.9(e), the Purchaser
shall designate a replacement for such director, which replacement the Company shall cause to be nominated for election to the Board of Directors at the annual, special or extraordinary meeting of shareholders of the Company the record date for which next follows the date on which such director ceased to be a director as a result of his or her death, disability, resignation or removal from the Board of Directors.(b)
        The Company shall cause each Purchaser Nominee designated for election to the Board of Directors pursuant toSection 5.9(a)to be included in the slate of nominees recommended by the Board of Directors to the shareholders of the Company for election as directors at the relevant meeting of the shareholders, and shall use its commercially reasonable efforts to cause the election of each such Purchaser Nominee, including soliciting proxies in favour of the election of such person.(c)
        Notwithstanding the foregoing provisions of thisSection 5.9, the Purchaser shall not be entitled to designate a Purchaser Nominee for election to the Board of Directors as of the first date on which the Purchaser no longer owns any Purchased Shares of the Company.  In the event that the Purchaser shall no longer be entitled to designate Purchaser Nominees for election to the Board of Directors pursuant to thisSection 5.9(c), the Purchaser shall cause any Purchaser Nominee then serving as a director to resign from the Board of Directors no later than the thirtieth (30th) day after the first day on which the Purchaser no longer owns any Purchased Shares of the Company.(d)
        If at any time that the Purchaser is entitled to designate a Purchaser Nominee
for election to the Board of Directors no Purchaser Nominee shall then be
elected and serving as a director on the Board of Directors, then until such
time as a Purchaser Nominee shall be elected to serve as a director the
Purchaser shall be entitled to designate one person (each such person, a
Board Observer) who
shall be permitted to attend all regular and special meetings of the Board of
Directors. Each Board Observer shall enter into the Companys standard form
 - 25 -

confidentiality agreement prior to acting as a Board Observer. The Company shall
(i) notify each Board Observer of any such meeting no later than the time at
which it notifies any member of the Board of Directors of such meeting and (ii)
provide to such Board Observer copies of all written or other materials
delivered to other members of the Board of Directors.(e)
        The Purchaser Nominee shall, at all times, be qualified and eligible to act as a director pursuant to the requirements of the Canada Business Corporations Act and the Securities Laws, as applicable.5.10Officer Share Transactions.  The Company shall use its commercially reasonable efforts to cause each of the Companys Chief Executive Officer and President, Chief Operating Officer, Director of Business Development, and Director of Finance to enter into an agreement on the Closing Date, which provides that he or she shall not, directly or indirectly, without the prior consent of the Purchaser, (i) offer, sell, contract to sell, secure, pledge, grant or sell any option, right or warrant to purchase, or otherwise lend, transfer or dispose of, or announce any intention to do so, any securities of the Company, or (ii) make any short sale, engage in any hedging transaction, or enter into any swap or other arrangement that transfers to
another Person any of the economic consequences of ownership of Common Shares (each, an Officer Disposition), for a period of 30 days following the Closing Date, and for the 30 days immediately following such initial 30 day period, the aggregate Officer Dispositions of any of such Scheduled Officer shall not exceed 50% of the aggregate number of Common Shares held by such Scheduled Officer on the Closing Date.  Each such agreement with such Scheduled Officers may contain customary exceptions to such restrictions, which exceptions shall be reasonably acceptable to the Purchaser.

5.11Compliance with Securities Laws.  The Purchaser shall comply with all applicable Securities Laws in connection with any resale of the Purchased Shares.

5.12Ordinary Course of Business.  The Company shall exercise commercially reasonable efforts to ensure that, until the Closing Date its operations and business are conducted only in the ordinary course, substantially in the same manner as currently conducted, including in such manner that:


(a)
        it shall not incur any indebtedness or obligation except in the ordinary course of business, and in a manner consistent with, past practices;(b)
        it shall not dispose of its Property (in whole or in part as may otherwise constitute a bulk sale), except in the ordinary course of business, and in a manner consistent with past practices;(c)
        it shall not dispose of or lose any of its title to or right to use any of the Intellectual Property Rights, except in the ordinary course of business, and in a manner consistent with past practices;(d)
        it shall maintain in force all policies of
insurance; and
 - 26 -

(e)
        it shall not enter or agree to enter into any transaction that may result in a Material Adverse Effect.The Company shall promptly notify the Purchaser of the occurrence or existence of any event or circumstance on or prior to the Closing Date by reason of which the Company has ceased to conduct its operations and business in the ordinary course as currently conducted or by reason of which the representations and warranties made by the Company herein have ceased to be true and correct in any material respect (or, in the case of representations and warranties qualified by materiality, in any respect).

5.13No Dividends.  From the date of this Agreement until the Closing Date, the Company shall not declare, pay or set aside for payment any dividend (including a dividend in specie or in kind) or other distribution to holders of any of its shares (including by way of return of capital).

- 27 -

and the Purchaser or, in the case of a
waiver, by the Party against whom enforcement of any such waiver is sought. No
waiver of any default with respect to any provision, condition or requirement of
this Agreement shall be deemed to be a continuing waiver in the future or a

or requirement hereof, nor shall any delay or omission of either Party to
exercise any right hereunder in any manner impair the exercise of any such
right.
