Each of the Company and the Subsidiaries is duly qualified to do business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, could not, individually or in the aggregate: (i) adversely affect the legality, validity or enforceability of any Transaction Document, (ii) have or result in or be reasonably likely to have or result in a material adverse effect on the results of operations, assets, prospects, business or condition (financial or otherwise) of the Company and the Subsidiaries, taken as a whole, or (iii) adversely impair the Company's ability to perform fully on a timely basis its obligations under any of the Transaction Documents (any of (i), (ii) or (iii), a "Material Adverse Effect").

The Company has the requisite corporate power and authority to enter into and to consummate the transactions contemplated by each of the Transaction Documents and otherwise to carry out its obligations hereunder or thereunder. The execution and delivery of each of the Transaction Documents by the Company and the consummation by it of the transactions contemplated hereby or thereby have been duly authorized by all necessary action on the part of the Company and no further consent or action is required by the Company other than Required Approvals. Each of the Transaction Documents has been (or upon delivery will be) duly executed by the Company and, when delivered in accordance with the terms hereof, will constitute the valid and binding obligation of the Company enforceable against the Company in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors' rights and remedies generally and general principles of equity. Neither the Company nor any Subsidiary is in violation of any of the provisions of its respective certificate or articles of incorporation, by-laws or other organizational or charter documents.

(d) No Conflicts. The execution, delivery and performance of the Transaction Documents by the Company and the consummation by the Company of the transactions contemplated thereby do not and will not: (i) conflict with or violate any provision of the Company's or any Subsidiary's certificate or articles of incorporation, bylaws or other organizational or charter documents, or (ii) subject to obtaining the Required Approvals, conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any agreement, credit facility, debt or other instrument (evidencing a Company or Subsidiary debt or otherwise) or other understanding to which the Company or any Subsidiary is a party or by which any property or asset of the Company or any Subsidiary is bound or

affected, or (iii) result, in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company or a Subsidiary is subject (including federal and state securities laws and regulations), or by which any property or asset of the Company or a Subsidiary is bound or affected; except in the case of each of clauses (ii) and (iii), such as could not, individually or in the aggregate, have or result in a Material Adverse Effect.

Neither the Company nor any Subsidiary is required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority or other Person in connection with the execution, delivery and performance by the Company of the Transaction Documents, other than (i) the filings required under Section 4.8, (ii) the filing with the Commission of the Underlying Shares Registration Statement, (iii) the notice and/or application(s) to each applicable Principal Market for the issuance and sale of the Debentures and Warrants and the listing of the Underlying Shares for trading thereon in the time and manner required thereby, and (iv) the filing of Form D with the Commission and applicable Blue Sky filings (collectively, the "Required Approvals").

The Company has reserved from its duly authorized capital stock a number of shares of Common Stock for issuance of the Underlying Shares at least equal to the Required Minimum on the date hereof. The Company has not, and to the knowledge of the Company, no Affiliate of the Company has sold, offered for sale or solicited offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the Purchasers, or that would be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Principal Market.

(p) Insurance.

A list of the Company's insurance contracts and policies are set forth on the Disclosure Schedules. To the best of Company's knowledge, such insurance contracts and policies are accurate and complete. Neither the Company nor any Subsidiary has any reason to believe it 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 without a significant increase in cost.

(q) Transactions With Affiliates and Employees. Except as set forth in SEC Reports, none of the officers or directors of the Company and, to the knowledge of the Company, none of the employees of the Company is presently a party to any transaction with the Company or any Subsidiary (other than for services as employees, officers and directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, or otherwise requiring payments to or from any officer, director or such employee or, to the knowledge of the Company, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee or partner.

(r) Internal Accounting Controls. The Company and the Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management's general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management's general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) for the Company and designed such

disclosures 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 Form 10-KSB or 10-QSB, 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 a date within 90 days prior to the filing date of the Form 10-QSB for the quarter ended January 31, 2003 (such date, the "Evaluation Date"). The Company presented in the Form 10-QSB for the quarter ended January 31, 2003 the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no significant changes in the Company's internal controls (as such term is defined in Item 307(b) of Regulation S-K under the Exchange Act) or, the Company's knowledge, in other factors that could significantly affect the Company's internal controls.

(s) Solvency/Indebtedness. Based on the financial condition of the Company as of each Closing Date: (i) the fair saleable value of the Company's assets exceeds the amount that will be required to be paid on or in respect of the Company's existing debts and other liabilities (including known contingent liabilities) as they mature; (ii) the Company's assets do not constitute unreasonably small capital to carry on its business for the current fiscal year as now conducted and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the business conducted by the Company, and projected capital requirements and capital availability thereof; and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its debt when such amounts are required to be paid. The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt). The Company has no knowledge of any facts or circumstances which lead it to believe that it will file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction within one year from the First Closing Date. The SEC Reports set forth as of the dates thereof all outstanding secured and unsecured Indebtedness of the Company or any Subsidiary, or for which the Company or any Subsidiary has commitments. For the purposes of this Agreement, "Indebtedness" shall mean (a) any liabilities for borrowed money or amounts owed in excess of $50,000 (other than trade accounts payable incurred in the ordinary course of business), (b) all guaranties, endorsements and other contingent obligations, whether or not the same are or should be reflected in the Company's balance sheet or the notes thereto, except guaranties by endorsement of negotiable instruments for deposit or collection in the ordinary course of business, and (c) the present value of any lease payments in excess of $50,000 due under leases required to be capitalized in accordance with GAAP. Neither the Company nor any Subsidiary is in default with respect to any Indebtedness.

(t) Certain Fees. No brokerage or finder's fees or commissions are or will be payable by the Company to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the

transactions contemplated by this Agreement, and the Company has not taken any action that would cause any Purchaser to be liable for any such fees or commissions.

(v) Listing and Maintenance Requirements.

Each of this Agreement, the Escrow Agreement and the Registration Rights Agreement has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof, will constitute the valid and legally binding obligation of such Purchaser, enforceable against it in accordance with its terms.

(b) Investment Intent. Such Purchaser is acquiring the Securities as principal for its own account for investment purposes only and not with a view to or for distributing or reselling such Securities or any part thereof, without prejudice, however, to such Purchaser's right, subject to the provisions of this Agreement, at all times to sell or otherwise dispose of all or any part of such Securities pursuant to an effective registration statement under the Securities Act or under an exemption from such registration and in compliance with applicable federal and state securities laws.

Such Purchaser does not have any agreement or understanding, directly or indirectly, with any Person to distribute any of the Securities.

ARTICLE IV
OTHER AGREEMENTS OF THE PARTIES

4.1 Transfer Restrictions.

(a) The Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Securities other than pursuant to an effective registration statement, to the Company or to an Affiliate of a Purchaser, the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and shall have the rights of a Purchaser under this Agreement and the Registration Rights Agreement.

(b) The Purchasers agree to the imprinting, so long as is required by this Section 4.1(b), of the following legend on any certificate evidencing Securities:

[NEITHER] THESE SECURITIES [NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE [EXERCISABLE] [CONVERTIBLE]] HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THESE SECURITIES AND THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY SUCH SECURITIES.

(c) The Company acknowledges and agrees that a Purchaser may from time to time pledge pursuant to a bona fide margin agreement or grant a security interest in some or all of the Securities and, if required under the terms of such arrangement, such Purchaser may transfer pledged or secured Securities to the pledgees or secured parties. If required by the Company's transfer agent in order to effect a pledge, the Company shall cause its counsel, at no cost to the Purchasers, to issue an opinion of counsel to the Company's transfer agent. Further, no notice shall be required of such pledge. At the appropriate Purchaser's expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities, including the preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of Selling Stockholders thereunder.

(d) Certificates evidencing Underlying Shares shall not contain any legend (including the legend set forth in Section 4.1(b) hereof): (i) while a registration statement (including the Underlying Shares Registration Statement) covering the resale of such security is effective under the Securities Act, or (ii) following any sale of such Underlying Shares pursuant to Rule 144, or (iii) if such Underlying Shares are eligible for sale under Rule 144(k), or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission); provided, however, in connection with the issuance of the Underlying Shares, each Purchaser, severally and not jointly with the other Purchasers, hereby agrees to adhere to and abide by all prospectus delivery requirements under the Securities Act and Commission Regulations. If all or any portion of a Debenture or Warrant is converted or exercised (as applicable) at a time when there is an effective registration statement to cover the resale of the Underlying Shares, or if such Underlying Shares may be sold under Rule 144(k) or if such legend is not otherwise required under applicable requirements of the Securities Act (including judicial interpretations thereof) then such Underlying Shares shall be issued free of all legends. The Company agrees that following the Effective Date or at such time as such legend is no longer required under this Section 4.1(d), it will, no later than five Trading Days following the delivery by a Purchaser to the Company or the Company's transfer agent of a certificate representing Underlying Shares issued with a restrictive legend, deliver or cause to be delivered to such Purchaser a certificate representing such shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section.

(e) In addition to such Purchaser's other available remedies, the Company shall pay to a Purchaser, in cash, as liquidated damages and not as a penalty, for each $1,000 of Underlying Shares (based on the Closing Price of the Common Stock on the date such Securities are submitted to the Company's transfer agent) delivered for removal of the restrictive legend and subject to Section 4.1(d), $10 per Trading Day (increasing to $20 per Trading Day 3 Trading Days after such damages have begun to accrue) for each

Trading Day after such fifth Trading Day until such certificate is delivered without a legend.

(f) Each Purchaser acknowledges that the Securities are subject to resale restrictions in British Columbia and may not be traded in British Columbia except as permitted by the Securities Act (British Columbia) and the rules made thereunder. In particular, pursuant to Multilateral Instrument 45-102, as adopted by the British Columbia Securities Commission, a subsequent trade in any of the Securities will be a distribution subject to the prospectus and registration requirements of applicable Canadian securities legislation, unless certain conditions are met, including the following:

(i) at least twelve months (the "Canadian Hold Period") shall have elapsed from the date on which the Convertible Debentures were issued to the Buyer;

(ii) during the currency of the Canadian Hold Period, any certificate representing the Securities is imprinted with a legend (the "Canadian Legend") stating:

"UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THE SECURITIES SHALL NOT TRADE THE SECURITIES BEFORE [INSERT THE DATE THAT IS TWELVE MONTHS AND A DAY AFTER THE DISTRIBUTION DATE."

(iii) the trade is not a control distribution (as defined in Multilateral Instrument 45-102);

(iv) no unusual effort is made to prepare the market or to create a demand for the Conversion Shares that are the subject of the trade;

(v) no extraordinary commission or consideration is paid to a person or company in respect of the trade; and

(iv) if the selling security holder is an insider or officer of the Company, the selling security holder has no reasonable grounds to believe that the Company is in default of securities legislation.

(g) By executing and delivering this Agreement, each Purchaser will have directed the Company not to include the Canadian Legend on any certificates representing the Securities to be issued to such Purchaser. As a consequence, the Purchaser will not be able to rely on the resale provisions of Multilateral Instrument 45-102, and any subsequent trade in the Securities during or after the Canadian Hold Period will be a distribution subject to the prospectus and registration requirements of Canadian securities legislation, to the extent that the trade is at that time subject to any such Canadian securities legislation.

4.2 Acknowledgment of Dilution. The Company acknowledges that the issuance of the Securities may result in dilution of the outstanding shares of Common Stock, which dilution may be substantial under certain market conditions. The Company further acknowledges that its obligations under the Transaction Documents, including without limitation its obligation to issue the Underlying Shares pursuant to the Transaction Documents, are unconditional and absolute and not subject to any right of set off, counterclaim, delay or reduction, regardless of the effect of any such dilution or any claim the Company may have against any Purchaser and regardless of the dilutive effect that such issuance may have on the ownership of the other stockholders of the Company.

4.3 Furnishing of Information. As long as any Purchaser owns Securities, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act. Upon the request of any Purchaser, the Company shall deliver to such Purchaser a written certification of a duly authorized officer as to whether it has complied with the preceding sentence. As long as any Purchaser owns Securities, if the Company is not required to file reports pursuant to such laws, it will prepare and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) such information as is required for the Purchasers to sell the Securities under Rule 144. The Company further covenants that it will take such further action as any holder of Securities may reasonably request, all to the extent required from time to time to enable such Person to sell such Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144.

4.4 Integration. The Company shall not, and shall use its best efforts to ensure that no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the Purchasers.

4.5 Reservation and Listing of Securities.

(a) The Company shall maintain a reserve from its duly authorized shares of Common Stock for issuance pursuant to the Transaction Documents in such amount as may be required to fulfill its obligations in full under the Transaction Documents.

(b) If, on any date, the number of authorized but unissued (and otherwise unreserved) shares of Common Stock is less than 200% of (i) the Actual Minimum on such date, minus (ii) the number of shares of Common Stock previously issued pursuant to the Transaction Documents, then the Board of Directors of the Company shall use commercially reasonable efforts to amend the Company's certificate or articles of incorporation to increase the number of authorized but unissued shares of Common Stock to at least the Required Minimum at such time (minus the number of shares of Common Stock previously issued pursuant to the Transaction Documents), as soon as possible and in any event not later than the 75th day after such date; provided that the Company will not be required at any time to authorize a number of shares of Common Stock greater

than the maximum remaining number of shares of Common Stock that could possibly be issued after such time pursuant to the Transaction Documents.

(c) The Company shall: (i) in the time and manner required by the Principal Market, prepare and file with such Principal Market an additional shares listing application covering a number of shares of Common Stock at least equal to the Required Minimum on the date of such application, (ii) take all steps necessary to cause such shares of Common Stock to be approved for listing on the Principal Market as soon as possible thereafter, (iii) provide to the Purchasers evidence of such listing, and (iv) maintain the listing of such Common Stock on such Principal Market or another Principal Market.

4.6 Conversion and Exercise Procedures. The form of Election to Purchase included in the Warrants and the form of Conversion Notice included in the Debentures set forth the totality of the procedures required of the Purchasers in order to exercise the Warrants or convert the Debentures. No additional legal opinion or other information or instructions shall be required of the Purchasers to exercise their Warrants or convert their Debentures. The Company shall honor exercises of the Warrants and conversions of the Debentures and shall deliver Underlying Shares in accordance with the terms, conditions and time periods set forth in the Transaction Documents.

4.7 Future Financings. From the date hereof until 120 days after the Effective Date, neither the Company nor any Subsidiary shall issue additional shares of Capital Shares or Capital Shares Equivalents for an effective price per share of Common Stock less than 140% of the then Set Price. Notwithstanding anything herein to the contrary, the 120 day period set forth in this Section 4.7 shall be extended for the number of Trading Days during such period in which (y) trading in the Common Stock is suspended by any Principal Market, or (z) following the Effective Date, the Registration Statement is not effective or the prospectus included in the Registration Statement may not be used by the Purchasers for the resale of the Underlying Shares. For purposes of this Section 4.7, Variable Rate Transactions and MFN Transactions shall automatically be deemed to be issued at an effective price per share less than the Set Price. The term "Variable Rate Transaction" shall mean a transaction in which the Company issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive additional shares of Common Stock either (x) at a conversion, exercise or exchange rate or other price that is based upon and/or varies with the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such debt or equity securities, or (y) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Stock. The term "MFN Transaction" shall mean a transaction in which the Company issues or sells any securities in a capital raising transaction or series of related transactions which grants to an investor the right to receive additional shares based upon future transactions of the Company on terms more favorable than those granted to the such investor in such offering. Notwithstanding anything to the contrary herein, this Section 4.7 shall not apply to the following (a) the granting of options to employees, officers and directors of the Company pursuant to any stock option plan duly adopted by a majority of the

non-employee members of the Board of Directors of the Company or a majority of the members of a committee of non-employee directors established for such purpose or the issuance of Common Stock to employees of the Company in lieu of cash compensation which issuance has been voted and agreed to by a majority of the non-employee members of the Board of Directors of the Company or a majority of the members of a committee of non-employee directors established for such purpose, or (b) the exercise of the Debenture or any other security issued by the Company in connection with the offer and sale of this Company's securities pursuant to this Agreement, or (c) the exercise of or conversion of any Convertible Securities, options, or warrants issued and outstanding on the Closing Date, or (d) acquisitions or strategic investments, the primary purpose of which is not to raise capital, or (e) financings undertaken with the prior consent of all of the Purchasers, which consent shall not unreasonably be withheld.

4.8 Securities Laws Disclosure; Publicity. The Company shall, by 8:30 a.m. Eastern time on the Trading Day following the date of this Agreement, issue a press release or file a Current Report on Form 8-K reasonably acceptable to each Purchaser disclosing all material terms of the transactions contemplated hereby. The Company and the Purchasers shall consult with each other in issuing any press releases with respect to the transactions contemplated hereby. Notwithstanding the foregoing, other than in any registration statement filed pursuant to the Registration Rights Agreement and filings related thereto, the Company shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the Commission or any regulatory agency or Principal Market, without the prior written consent of such Purchaser, except to the extent such disclosure is required by law or Principal Market regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure.

4.9 Non-Public Information. The Company covenants and agrees that neither it nor any other Person acting on its behalf will provide any Purchaser or its agents or counsel with any information that the Company believes constitutes material non-public information, unless prior thereto such Purchaser shall have executed a written agreement regarding the confidentiality and use of such information. The Company understands and confirms that each Purchaser shall be relying on the foregoing representations in effecting transactions in securities of the Company.

4.10 Use of Proceeds. The Company shall use the net proceeds from the sale of the Securities hereunder for working capital purposes and not for the satisfaction of any portion of the Company's debt (other than payment of trade payables, capital lease obligations, and accrued expenses in the ordinary course of the Company's business and prior practices), to redeem any Company equity or equity-equivalent securities or to settle any outstanding litigation; provided, however, the Company shall apply the proceeds from the First Closing and if necessary, the Second and Third Closings, first to the repayment of approximately $252,500 outstanding principal and interest under the senior short-term promissory note held by Cornell Capital Partners, LP., second to the repayment of up to $280,000 of amounts due under the promissory note held by TRW Automotive U.S. LLC, as assignee of TRW, Inc., third to the payment of CDN$63,393.50 due on invoices rendered by KPMG LLP for professional services rendered, and fourth to the repayment of $121,657.53 outstanding principal and interest under convertible debentures held by Cornell Capital Partners, LP.

4.11 Reimbursement. If any Purchaser becomes involved in any capacity in any Proceeding by or against any Person who is a stockholder of the Company, solely as a result of such Purchaser's acquisition of the Securities under this Agreement and without causation by any other activity, obligation, condition or liability pertaining to such Purchaser and not to the transactions contemplated by this Agreement, the Company will reimburse such Purchaser, to the extent such reimbursement is not provided for in Section 4.12, for its reasonable legal and other expenses (including the cost of any investigation, preparation and travel in connection therewith) incurred in connection therewith, as such expenses are incurred. The reimbursement obligations of the Company under this paragraph shall be in addition to any liability which the Company may otherwise have, shall extend upon the same terms and conditions to any Affiliates of the Purchasers who are actually named in such action, proceeding or investigation, and partners, directors, agents, employees and controlling persons (if any), as the case may be, of the Purchasers and any such Affiliate, and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company, the Purchasers and any such Affiliate and any such Person. The Company also agrees that neither the Purchasers nor any such Affiliates, partners, directors, agents, employees or controlling persons shall have any liability to the Company or any Person asserting claims on behalf of or in right of the Company solely as a result of acquiring the Securities under this Agreement.

4.12 Indemnification of Purchasers. Subject to the provisions of this Section 4.12, the Company will indemnify and hold the Purchasers and their directors, officers, shareholders, partners, employees and agents (each, a "Purchaser Party") harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, 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 any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents. 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 defense 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 defense 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 defense 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 will not be liable to any Purchaser Party under this Agreement (i) for any settlement by an Purchaser Party effected without the Company's prior written consent, which shall not be unreasonably withheld or delayed; or (ii) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party's breach of any of the representations, warranties, covenants or agreements made by the Purchasers in this Agreement or in the other Transaction Documents.

4.13 Shareholders Rights Plan. In the event that a shareholders rights plan is adopted by the Company, no claim will be made or enforced by the Company or any other Person that

any Purchaser is an "Acquiring Person" under the plan or in any way could be deemed to trigger the provisions of such plan by virtue of receiving Securities under the Transaction Documents.

4.14. Participation in Future Financing. From the date hereof until 12 months after the Effective Date, the Company shall not effect a financing of its Capital Shares or Capital Shares Equivalents (a "Subsequent Financing") unless (i) the Company delivers to each of such Purchasers a written notice at least 5 Trading Days prior to the closing of such Subsequent Financing (the "Subsequent Financing Notice") of its intention to effect such Subsequent Financing, which Subsequent Financing Notice shall describe in reasonable detail the proposed terms of such Subsequent Financing, the amount of proceeds intended to be raised thereunder, the Person with whom such Subsequent Financing is proposed to be effected, and attached to which shall be a term sheet or similar document relating thereto and (ii) such Purchaser shall not have notified the Company by 6:30 p.m. (New York City time) on the fifth (5^th) Trading Day after its receipt of the Subsequent Financing Notice of its willingness to provide (or to cause its designee to provide), subject to completion of mutually acceptable documentation, all or part of such financing to the Company on the same terms set forth in the Subsequent Financing Notice. If one or more Purchasers shall fail to so notify the Company of their willingness to participate in the Subsequent Financing, the Company may effect the remaining portion of such Subsequent Financing on the terms and to the Persons set forth in the Subsequent Financing Notice; provided that the Company must provide the Purchasers with a second Subsequent Financing Notice, and the Purchasers will again have the right of first refusal set forth above in this Section 4.14, if the Subsequent Financing subject to the initial Subsequent Financing Notice is not consummated for any reason on the terms set forth in such Subsequent Financing Notice within 60 Trading Days after the date of the initial Subsequent Financing Notice with the Person identified in the Subsequent Financing Notice. In the event the Company receives responses to Subsequent Financing Notices from Purchasers seeking to purchase more than the financing sought by the Company in the Subsequent Financing such Purchasers shall have the right to purchase their Pro Rata Portion (as defined below) of the Capital Shares or Capital Shares Equivalents to be issued in such Subsequent Financing. "Pro Rata Portion" is the ratio of (x) the principal amount of Debentures purchased by a Purchaser and (y) the sum of the aggregate principal amount of Debentures issued hereunder. If any Purchaser no longer holds any Debentures, then the Pro Rata Portions shall be re-allocated among the remaining Purchasers. Notwithstanding anything to the contrary herein, this Section 4.14 shall not apply to the following (a) the granting of options to employees, officers and directors of the Company pursuant to any stock option plan duly adopted by a majority of the non-employee members of the Board of Directors of the Company or a majority of the members of a committee of non-employee directors established for such purpose or the issuance of Common Stock to employees of the Company in lieu of cash compensation which issuance has been voted and agreed to by a majority of the non-employee members of the Board of Directors of the Company or a majority of the members of a committee of non-employee directors established for such purpose, or (b) the exercise of the Debenture or any other security issued by the Company in connection with the offer and sale of this Company's securities pursuant to this Agreement, or (c) the exercise of or conversion of any Convertible Securities, options, or warrants issued and outstanding on the Closing Date, or (d) acquisitions or strategic investments, the primary purpose of which is not to raise capital.

5.7 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Purchasers. Any Purchaser may assign its rights under this Agreement and the Registration Rights Agreement to any Person to whom such Purchaser assigns or transfers any Securities.

5.8 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Sections 4.12.

5.9 Governing Law; Venue; Waiver of Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. The parties hereby waive all rights to a trial by jury. If either party shall commence an action or proceeding to enforce any provisions of this Agreement, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its attorneys fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

5.10 Survival. The representations, warranties, agreements and covenants contained herein shall survive each Closing and the delivery, exercise and/or conversion of the Securities, as applicable.

5.11 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission, such signature shall create a valid and binding

obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile signature page were an original thereof.

5.12 Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

5.13 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights, provided, however, in the case of a rescission of a conversion of a Debenture or exercise of a Warrant, the Purchaser shall be required to return any shares of Common Stock subject to any such conversion or exercise notice.

5.14 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity, if requested. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities.

5.15 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby agrees to waive in any action for specific performance of any such obligation the defense that a remedy at law would be adequate. Without limiting the generality of the foregoing, the Company expressly agrees that its breach of the next-to-last last sentence of Section 4.7 would cause each Purchaser irreparable harm, and consents to the granting of injunctive relief by any court having jurisdiction to preclude any such issuance of securities.

5.16 Payment Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any

law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

5.17 Usury. To the extent it may lawfully do so, the Company hereby agrees not to insist upon or plead or in any manner whatsoever claim, and will resist any and all efforts to be compelled to take the benefit or advantage of, usury laws wherever enacted, now or at any time hereafter in force, in connection with any claim, action or proceeding that may be brought by any Purchaser in order to enforce any right or remedy under any Transaction Document. Notwithstanding any provision to the contrary contained in any Transaction Document, it is expressly agreed and provided that the total liability of the Company under the Transaction Documents for payments in the nature of interest shall not exceed the maximum lawful rate authorized under applicable law (the "Maximum Rate"), and, without limiting the foregoing, in no event shall any rate of interest or default interest, or both of them, when aggregated with any other sums in the nature of interest that the Company may be obligated to pay under the Transaction Documents exceed such Maximum Rate. It is agreed that if the maximum contract rate of interest allowed by law and applicable to the Transaction Documents is increased or decreased by statute or any official governmental action subsequent to the date hereof, the new maximum contract rate of interest allowed by law will be the Maximum Rate applicable to the Transaction Documents from the effective date forward, unless such application is precluded by applicable law. If under any circumstances whatsoever, interest in excess of the Maximum Rate is paid by the Company to any Purchaser with respect to indebtedness evidenced by the Transaction Documents, such excess shall be applied by such Purchaser to the unpaid principal balance of any such indebtedness or be refunded to the Company, the manner of handling such excess to be at such Purchaser's election.

5.18 Independent Nature of Purchasers' Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any Transaction Document, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Document. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. Each Purchaser was introduced to the Company HPC Capital Management, which has acted solely as agent for the Company and not for any Purchaser. Each Purchaser has been represented by its own separate legal counsel in their review and negotiation of the Transaction Documents. For reasons of administrative convenience only, Purchasers and their respective counsel have chosen to communicate with the Company through FW. FW does not represent all of the Purchasers but only Palisades Master Fund, L.P.. The Company has elected to provide all Purchasers with the same terms and

Transaction Documents for the convenience of the Company and not because it was required or requested to do so by the Purchasers.

5.19 Liquidated Damages. The Company's obligations to pay any liquidated damages or other amounts owing under the Transaction Documents is a continuing obligation of the Company and shall not terminate until all unpaid liquidated damages and other amounts have been paid notwithstanding the fact that the instrument or security pursuant to which such liquidated damages or other amounts are due and payable shall have been canceled.

IN WITNESS WHEREOF, the parties hereto have caused this Securities Purchase Agreement to be duly executed by their respective authorized signatories as of the date first indicated above.

EXHIBIT A

NEITHER THESE SECURITIES NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE CONVERTIBLE HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THESE SECURITIES AND THE SECURITIES ISSUABLE UPON CONVERSION OF THESE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY SUCH SECURITIES.

Date of Issuance: _________ __, 2003

$_______________

7% CONVERTIBLE DEBENTURE
DUE _______________ __, 2005

THIS DEBENTURE is one of a series of duly authorized and issued Debentures of SmarTire Systems, Inc., a Yukon Territory corporation, having a principal place of business at _______________________ (the "Company"), designated as its 7% Convertible Debenture, due _______________ __, 2005 (the "Debentures").

FOR VALUE RECEIVED, the Company promises to pay to ________________________ or its registered assigns (the "Holder"), the principal sum of $_______________ on _______________ __, 2005 or such earlier date as the Debentures are required or permitted to be repaid as provided hereunder (the "Maturity Date") and to pay interest to the Holder on the aggregate unconverted and then outstanding principal amount of this Debenture at the rate of 7% per annum, payable quarterly on March 1, June 1, September 1 and December 1, beginning on the first such date after the Original Issue Date and on each Conversion Date (as to that principal amount then being converted) and on the Maturity Date (except that, if any such date is not a Business Day, then such payment shall be due on the next succeeding Business Day) (each such date, an "Interest Payment Date"), in cash or shares of Common Stock at the Interest Conversion Rate, or a combination thereof; provided,

however, payment in shares of Common Stock may only occur if: (i) there is an effective Underlying Shares Registration Statement pursuant to which the Holder is permitted to utilize the prospectus thereunder to resell all of the shares of Common Stock to be issued in lieu of cash (and the Company believes, in good faith, that such effectiveness will continue uninterrupted for the foreseeable future), (ii) the Common Stock is listed for trading on a Principal Market (and the Company believes, in good faith, that trading of the Common Stock on a Principal Market will continue uninterrupted for the foreseeable future), (iii) there is a sufficient number of authorized but unissued and otherwise unreserved shares of Common Stock for the issuance of all of the share issuable pursuant to the Transaction Documents, including the shares to be issued for interest in lieu of cash and (iv) such issuance would be permitted in full without violating the limitations set forth in clauses (A) of Section 4(a)(ii) and such issuance and the issuance of all Underlying Shares, assuming conversion or exercise in full, as the case may be, of the Debenture and Warrants would be permitted in full without violating the limitations set forth in clause (B) of section 4(a)(ii). Subject to the terms and conditions herein, the decision whether to pay interest hereunder in shares of Common Stock or cash shall be at the discretion of the Company. Not less than 20 Trading Days prior to each Interest Payment Date, the Company shall provide the Holder with written notice of its election to pay interest hereunder either in cash or shares of Common Stock (the Company may indicate in such notice that the election contained in such notice shall continue for later periods until revised). Within 20 Trading Days prior to an Interest Payment Date, the Company's election (whether specific to an Interest Payment Date or continuous) shall be irrevocable as to such Interest Payment Date. Subject to the aforementioned conditions, failure to timely provide such written notice shall be deemed an election by the Company to pay the interest on such Interest Payment Date in cash. Interest shall be calculated on the basis of a 360-day year and shall accrue daily commencing on the Original Issue Date until payment in full of the principal sum, together with all accrued and unpaid interest and other amounts which may become due hereunder, has been made. Payment of interest in shares of Common Stock shall otherwise occur pursuant to Section 4(b) and only for purposes of the payment of interest in shares, the Interest Payment Date shall be deemed the Conversion Date. Interest shall cease to accrue with respect to any principal amount converted, provided that the Company in fact delivers the Underlying Shares within the time period required by Section 4(b)(i). Interest hereunder will be paid to the Person in whose name this Debenture is registered on the records of the Company regarding registration and transfers of Debentures (the "Debenture Register"). Except as otherwise provided herein, if at anytime the Company pays interest partially in cash and partially in shares of Common Stock, then such payment shall be distributed ratably among the Holders based upon the principal amount of Debentures held by each Holder. All overdue accrued and unpaid interest to be paid hereunder shall entail a late fee at the rate of 18% per annum (or such lower maximum amount of interest permitted to be charged under applicable law) ("Late Fee") which will accrue daily, from the date such interest is due hereunder through and including the date of payment. The Company may not prepay any portion of the principal amount on this Debenture without the prior written consent of the Holder.

This Debenture is subject to the following additional provisions:

Section 1. This Debenture is exchangeable for an equal aggregate principal amount of Debentures of different authorized denominations, as requested by the Holder surrendering the same. No service charge will be made for such registration of transfer or exchange.

Section 2. This Debenture has been issued subject to certain investment representations of the original Holder set forth in the Purchase Agreement and may be transferred or exchanged only in compliance with the Purchase Agreement and applicable federal, state and provincial securities laws and regulations. Prior to due presentment to the Company for transfer of this Debenture, the Company and any agent of the Company may treat the Person in whose name this Debenture is duly registered on the Debenture Register as the owner hereof for the purpose of receiving payment as herein provided and for all other purposes, whether or not this Debenture is overdue, and neither the Company nor any such agent shall be affected by notice to the contrary.

Section 3. Events of Default.

(a) "Event of Default", wherever used herein, means any one of the following events (whatever the reason and whether it shall be voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court, or any order, rule or regulation of any administrative or governmental body):

(i) any default in the payment of the principal of, interest on or liquidated damages in respect of, any Debentures, free of any claim of subordination, as and when the same shall become due and payable (whether on a Conversion Date or the Maturity Date or by acceleration or otherwise) which default is not cured, if possible to cure, within five (5) days of notice of such default sent by the Holder;

(ii) the Company shall fail to observe or perform any other covenant, agreement or warranty contained in, or otherwise commit any breach of any of the Transaction Documents (other than a breach by the Company of its obligations to deliver shares of Common Stock to the Holder upon conversion or interest payment which breach is addressed in clause (x) below) which is not cured, if possible to cure, within 15 days of notice of such default sent by the Holder (except with respect to breaches pursuant to Sections 4.1, 4.7 and 4.14 of the Purchase Agreement and Section 3(a) of the Warrant);

(iii) the Company or any of its subsidiaries shall commence, or there shall be commenced against the Company or any such subsidiary a case under any applicable bankruptcy or insolvency laws as now or hereafter in effect or any successor thereto, or the Company commences any other proceeding under any reorganization, arrangement, adjustment of debt, relief of debtors, dissolution, insolvency or liquidation or similar law of any jurisdiction whether now or hereafter in effect relating to the Company or any subsidiary thereof or there is commenced

against the Company or any subsidiary thereof any such bankruptcy, insolvency or other proceeding which remains undismissed for a period of 60 days; or the Company or any subsidiary thereof is adjudicated insolvent or bankrupt; or any order of relief or other order approving any such case or proceeding is entered; or the Company or any subsidiary thereof suffers any appointment of any custodian or the like for it or any substantial part of its property which continues undischarged or unstayed for a period of 60 days; or the Company or any subsidiary thereof makes a general assignment for the benefit of creditors; or the Company shall fail to pay, or shall state that it is unable to pay, its debts generally as they become due; or the Company or any subsidiary thereof shall call a meeting of its creditors with a view to arranging a composition, adjustment or restructuring of its debts; or the Company or any subsidiary thereof shall by any act or failure to act expressly indicate its consent to, approval of or acquiescence in any of the foregoing; or any corporate or other action is taken by the Company or any subsidiary thereof for the purpose of effecting any of the foregoing;

(iv) the Company shall default in any of its obligations under any other Debenture or any mortgage, credit agreement or other facility, indenture agreement, factoring agreement or other instrument under which there may be issued, or by which there may be secured or evidenced any indebtedness for borrowed money or money due under any long term leasing or factoring arrangement of the Company in an amount exceeding $150,000, whether such indebtedness now exists or shall hereafter be created and such default shall result in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise become due and payable which default is not cured, if possible to cure, within 15 days of such default occurring, provided, if cured within 15 days, the breach or default, as the case may be, shall have been waived by the other party to such agreement or instrument;

(v) the Common Stock shall not be eligible for quotation on or quoted for trading on the Principal Market and shall not again be eligible for and quoted or listed for trading on another Principal Market within five (5) Trading Days;

(vi) the Company shall agree to sell or dispose of all or in excess of 33% of its assets in one or more transactions (whether or not such sale would constitute a Change of Control Transaction) or shall redeem or repurchase more than a de minimis number of its outstanding shares of Common Stock or other equity securities of the Company;

(vii) an Underlying Shares Registration Statement shall not have been declared effective by the Commission on or prior to the 180th calendar day after the Original Issue Date;

(viii) if, during the Effectiveness Period (as defined in the Registration Rights Agreement), the effectiveness of the Underlying Shares Registration Statement lapses for any reason or the Holder shall not be permitted to resell Registrable Securities (as defined in the Registration Rights Agreement) under the Underlying Shares Registration Statement, in either case, for more than 10 consecutive Trading Days or 20 non-consecutive Trading Days during any 12 month period; provided, however, such 10 consecutive Trading Day period shall be extended by up to a total of 60 consecutive calendar days in any 12 month period for any lapse that occurs in connection with the occurrence or existence of any pending corporate development with respect to the Company that is material and that, in the unanimous determination of the Board of Directors of the Company, makes it not in the best interest of the Company to allow any required public disclosure and the continued availability of the Registration Statement or Prospectus; provided, further, that the Company timely pays any liquidated damages due during such period to the Holder;

(ix) an Event (as defined in the Registration Rights Agreement) shall not have been cured to the satisfaction of the Holder prior to the expiration of thirty days from the Event Date (as defined in the Registration Rights Agreement) relating thereto (other than an Event resulting from a failure of an Underlying Shares Registration Statement to be declared effective by the Commission on or prior to the Effectiveness Date (as defined in the Registration Rights Agreement), which shall be covered by Section 3(a)(vii));

(x) the Company shall fail for any reason to deliver certificates to a Holder prior to the fifth Trading Day after a Conversion Date pursuant to and in accordance with Section 4(b) or the Company shall provide notice to the Holder, including by way of public announcement, at any time, of its intention not to comply with requests for conversions of any Debentures in accordance with the terms hereof; or

(xi) the Company shall fail for any reason to deliver the payment in cash pursuant to a Buy-In (as defined herein) within five (5) days after notice thereof is delivered hereunder.

(b) If any Event of Default occurs and is continuing, the full principal amount of this Debenture (and, at the Holder's option, all other Debentures then held by such Holder), together with interest and other amounts owing in respect thereof, to the date of acceleration shall become at the Holder's election, immediately due and payable in cash. The aggregate amount payable upon an Event of Default shall be equal to the Mandatory Prepayment Amount. Interest shall accrue on the Mandatory Prepayment Amount hereunder from the fifth (5^th) day after such amount is due (being the date of an Event of Default) through the date of prepayment in full thereof in an amount equal to

the Late Fee, to accrue daily from the date such payment is due hereunder through and including the date of payment. All Debentures for which the full prepayment price hereunder shall have been paid in accordance herewith shall promptly be surrendered to or as directed by the Company. The Holder need not provide and the Company hereby waives any presentment, demand, protest or other notice of any kind, and the Holder may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Such declaration may be rescinded and annulled by Holder at any time prior to payment hereunder and the Holder shall have all rights as a Debenture holder until such time, if any, as the full payment under this Section shall have been received by it. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon.

Section 4. Conversion.

(a) (i) At any time after the Closing Date, this Debenture shall be convertible into shares of Common Stock at the option of the Holder, in whole or in part at any time and from time to time (subject to the limitations on conversion set forth in Section 4(a)(ii) hereof). The Holder shall effect conversions by delivering to the Company the form of conversion notice attached hereto as Annex A (a "Conversion Notice"), specifying therein the principal amount of Debentures to be converted and the date on which such conversion is to be effected (a "Conversion Date") and shall contain a completed schedule in the form of Schedule 1 to the Conversion Notice (as amended on each Conversion Date, the "Conversion Schedule") reflecting the remaining principal amount of this Debenture and all accrued and unpaid interest thereon subsequent to the conversion at issue. If no Conversion Date is specified in a Conversion Notice, the Conversion Date shall be the date that such Conversion Notice is provided hereunder. To effect conversions hereunder, the Holder shall not be required to physically surrender Debentures to the Company unless the entire principal amount of this Debenture has been so converted. Conversions hereunder shall have the effect of lowering the outstanding principal amount of this Debenture plus all accrued and unpaid interest thereon in an amount equal to the applicable conversion, which shall be evidenced by entries set forth in the Conversion Schedule. The Holder and the Company shall maintain records showing the principal amount converted and the date of such conversions. The Company shall deliver any objection to the figures represented in the Conversion Schedules within one (1) Business Day of receipt of such notice. In the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative in the absence of manifest error. The Holder and any assignee, by acceptance of this Debenture, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of a portion of this Debenture, the unpaid and unconverted principal amount of this Debenture may be less than the amount stated on the face hereof. In the event a Holder of this Debenture shall elect to convert any or all of the outstanding principal amount hereof, the Company may not refuse conversion based

on any claim that the Holder or any one associated or affiliated with the Holder of has been engaged in any violation of law, agreement or for any other reason, unless, an injunction from a court, on notice, restraining and or enjoining conversion of all or part of this Debenture shall have been sought and obtained and the Company posts a surety bond for the benefit of the Holder in the amount of 150% of the principal amount of this Debenture outstanding, which is subject to the injunction, which bond shall remain in effect until the completion of arbitration/litigation of the dispute and the proceeds of which shall be payable to such Holder to the extent it obtains judgment. In the absence of an injunction precluding the same, the Company shall issue Conversion Shares or, if applicable, cash, upon a properly noticed conversion. Nothing herein shall limit a Holder's right to pursue actual damages or declare an Event of Default pursuant to Section 3 herein for the Company's failure to deliver Conversion Shares within the period specified herein and such Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit the Holders from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

(ii) Beneficial Ownership Restrictions. A Holder may not convert Debentures or receive shares of Common Stock as payment of interest hereunder to the extent such conversion or receipt of such interest payment would result in the Holder, together with its Affiliates, beneficially owning (as determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder) in excess of 4.99% of the then issued and outstanding shares of Common Stock, including shares issuable upon conversion of, and payment of interest on, the Debentures held by such Holder after application of this Section. The Holder shall be entitled to rely on the Company's public filing with respect to the number of shares of Common Stock which are then issued and outstanding, and the Holder may inquire of the Company's Chief Financial Officer to obtain a more current number, which shall be provided within two (2) Business Days of written request therefor. To ensure compliance with this restriction, the Holder will be deemed to represent to the Company each time it delivers a Conversion Notice that such Conversion Notice has not violated the restrictions set forth in this paragraph. If the Holder has delivered a Conversion Notice for a principal amount of Debentures that, without regard to any other shares that the Holder or its affiliates may beneficially own, would result in the issuance in excess of the permitted amount hereunder, the Company shall honor the conversion for the maximum principal amount permitted to be converted on such Conversion Date in accordance with the periods described in Section 4(b) and, at the option of the Holder with notice to the Company, either retain any principal amount tendered for conversion in excess of the permitted amount hereunder for future conversions or return such excess principal amount to the Holder. In the event of a merger or consolidation of the Company with or into another Person, this paragraph

shall not apply with respect to a determination of the number of shares of common stock issuable upon conversion in full of the Debentures if such determination is necessary to establish the Securities or other assets which the holder of Common Stock shall be entitled to receive upon the effectiveness of such merger or consolidation. The provisions of this Section 4(a)(ii)(A) may be waived by the Holder at the election of the Holder upon not less than 61 days' prior notice to the Company, and the provisions of this Section 4(a)(ii)(A) shall continue to apply until such 61^st day (or such later date, as determined by the Holder, as may be specified in such notice of waiver). No conversion of this Debenture in violation of this Section 4(a)(ii)(A) but otherwise in accordance with this Debenture shall affect the status of the Underlying Shares as validly issued, fully-paid and nonassessable.

(iii) Underlying Shares Issuable Upon Conversion and Pursuant to Interest.

(A) Conversion of Principal Amount. The number of shares of Common Stock issuable upon a conversion shall be determined by the quotient obtained by dividing (x) the outstanding principal amount of this Debenture to be converted and (y) the Set Price, and

(B) Payment of Interest in Underlying Shares. The number of shares of Common Stock issuable upon payment of interest under this Debenture shall be the number determined by (x) the product of (I) the outstanding principal amount of this Debenture to be converted and (II) the product of (aa) the quotient obtained by dividing 7% by 360 and (bb) the number of days for which such principal amount was outstanding, divided by (y) the applicable Interest Conversion Rate, provided, that if the Company shall have elected to pay the interest due on an Interest Payment Date in cash pursuant to the terms hereof, this subsection (B) shall not be used in the calculation of the number of shares of Common Stock issuable upon a conversion hereunder.

(b) (i) Not later than five (5) Trading Days after any Conversion Date, the Company will deliver to the Holder (A) a certificate or certificates for the shares of Common Stock which shall be free of restrictive legends and trading restrictions (other than those required by the Purchase Agreement) representing the number of shares of Common Stock being acquired upon the conversion of Debentures (including, if so elected by the Company, shares of Common Stock representing the payment of accrued interest) and (B) a bank check in the amount of accrued and unpaid interest (if the Company has timely elected or is required to pay accrued interest in cash). The Company shall, upon request of the Holder, if available and if allowed under applicable securities laws, use its best efforts to deliver any certificate or certificates required to be delivered by the Company under this Section electronically through the Depository Trust Corporation or another established

clearing corporation performing similar functions. If in the case of any Conversion Notice such certificate or certificates are not delivered to or as directed by the applicable Holder by the fifth (5^th) Trading Day after a Conversion Date, the Holder shall be entitled by written notice to the Company at any time on or before its receipt of such certificate or certificates thereafter, to rescind such conversion, in which event the Company shall immediately return the certificates representing the principal amount of Debentures tendered for conversion.

(ii) If the Company fails for any reason to deliver to the Holder such certificate or certificates pursuant to Section 4(b)(i) by the fifth (5^th) Trading Day after the Conversion Date, the Company shall pay to such Holder, in cash, as liquidated damages and not as a penalty, for each $5,000 of principal amount being converted, $50 per Trading Day (increasing to $100 per Trading Day after five (5) Trading Days and increasing to $200 per Trading Day ten (10) Trading Days after such damages begin to accrue) for each Trading Day after such third Trading Day until such certificates are delivered. Nothing herein shall limit a Holder's right to pursue actual damages or declare an Event of Default pursuant to Section 3 herein for the Company's failure to deliver certificates representing shares of Common Stock upon conversion within the period specified herein and such Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit the Holders from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

(iii) In addition to any other rights available to the Holder, if the Company fails for any reason to deliver to the Holder such certificate or certificates pursuant to Section 4(b)(i) by the fifth (5^th) Trading Day after the Conversion Date, and if after such fifth (5^th) Trading Day the Holder is required by its brokerage firm to purchase (in an open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale by such Holder of the Underlying Shares which the Holder anticipated receiving upon such conversion (a "Buy-In"), then the Company shall (A) pay in cash to the Holder (in addition to any remedies available to or elected by the Holder) the amount by which (x) the Holder's total purchase price (including brokerage commissions, if any) for the Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that such Holder anticipated receiving from the conversion at issue multiplied by (2) the actual sale price of the Common Stock at the time of the sale (including brokerage commissions, if any) giving rise to such purchase obligation and (B) at the option of the Holder, either reissue Debentures in principal amount equal to the principal amount of the attempted conversion or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its delivery requirements under Section 4(b)(i). For example, if the Holder purchases Common Stock having a total purchase

price of $11,000 to cover a Buy-In with respect to an attempted conversion of Debentures with respect to which the actual sale price of the Underlying Shares at the time of the sale (including brokerage commissions, if any) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In. Notwithstanding anything contained herein to the contrary, if a Holder requires the Company to make payment in respect of a Buy-In for the failure to timely deliver certificates hereunder and the Company timely pays in full such payment, the Company shall not be required to pay such Holder liquidated damages under Section 4(b)(ii) in respect of the certificates resulting in such Buy-In.

(c) (I) The conversion price in effect on any Conversion Date shall be equal to $____ (subject to adjustment herein)(the "Set Price").

(ii) If the Company, at any time while the Debentures are outstanding: (A) shall pay a stock dividend or otherwise make a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company pursuant to this Debenture, including interest thereon), (B) subdivide outstanding shares of Common Stock into a larger number of shares, (C) combine (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (D) issue by reclassification of shares of the Common Stock any shares of capital stock of the Company, then the Set Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding before such event and of which the denominator shall be the number of shares of Common Stock outstanding after such event. Any adjustment made pursuant to this Section shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

(iii) If the Company, at any time while Debentures are outstanding, shall issue rights, options or warrants to all holders of Common Stock (and not to Holders) entitling them to subscribe for or purchase shares of Common Stock or Common Stock Equivalents at a price per share less than the Closing Price at the record date

mentioned below, then the Set Price shall be adjusted by multiplying the Set Price in effect immediately prior to such record date by a fraction, of which the denominator shall be the number of shares of the Common Stock (excluding treasury shares, if any) outstanding on the date of issuance of such rights or warrants plus the number of additional shares of Common Stock offered for subscription or purchase, and of which the numerator shall be the number of shares of the Common Stock (excluding treasury shares, if any) outstanding on the date of issuance of such rights or warrants plus the number of shares which the aggregate offering price of the total number of shares so offered would purchase at the Closing Price on the record date. Such adjustment shall be made whenever such rights or warrants are issued, and shall become effective immediately after the record date for the determination of stockholders entitled to receive such rights, options or warrants.

(iv) [RESERVED]

(v) In case of any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is converted into other securities, cash or property, the Holders shall have the right thereafter to, at their option, (A) convert the then outstanding principal amount, together with all accrued but unpaid interest and any other amounts then owing hereunder in respect of this Debenture only into the shares of stock and other securities, cash and property receivable upon or deemed to be held by holders of the Common Stock following such reclassification or share exchange, and the Holders of the Debentures shall be entitled upon such event to receive such amount of securities, cash or property as the shares of the Common Stock of the Company into which the then outstanding principal amount, together with all accrued but unpaid interest and any other amounts then owing hereunder in respect of this Debenture could have been converted immediately prior to such reclassification or share exchange would have been entitled or (B) require the Company to prepay the aggregate of its outstanding principal amount of Debentures, plus all interest and other amounts due and payable thereon, at a price determined in accordance with Section 3(b). The entire prepayment price shall be paid in cash. This provision shall similarly apply to successive reclassifications or share exchanges.

(vi) All calculations under this Section 4 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 4, the number of shares of Common Stock deemed to be outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) outstanding.

(vii) If (A) the Company shall declare a dividend (or any other distribution) on the Common Stock; (B) the Company shall declare a special nonrecurring cash dividend

on or a redemption of the Common Stock; (C) the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights; (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, of any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property; (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company; then, in each case, the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of the Debentures, and shall cause to be mailed to the Holders at their last addresses as they shall appear upon the stock books of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided, that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. Holders are entitled to convert Debentures during the 20-day period commencing the date of such notice to the effective date of the event triggering such notice.

(viii) If, at any time while this Debenture is outstanding, (A) the Company effects any merger or consolidation of the Company with or into another Person, (B) the Company effects any sale of all or substantially all of its assets in one or a series of related transactions, (C) any tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property, or (D) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (in any such case, a "Fundamental Transaction"), then upon any subsequent conversion of this Debenture, the Holder shall have the right to receive, for each Underlying Share that would have been issuable upon such conversion absent such Fundamental Transaction, the same kind and amount of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been,

immediately prior to such Fundamental Transaction, the holder of one share of Common Stock (the "Alternate Consideration"). For purposes of any such conversion, the determination of the Set Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Set Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Debenture following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a new Debenture consistent with the foregoing provisions and evidencing the Holder's right to convert such Debenture into Alternate Consideration. The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this paragraph (c) and insuring that this Debenture (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction. In the event a Change of Control Transaction, including any Fundamental Transaction constituting a Change of Control Transaction, the Holder may request, before the 90th day after such Change of Control Transaction, that the Company (or any such successor or surviving entity) will purchase the Debenture from the Holder for a purchase price, payable in cash within five Trading Days after such request (or, if later, on the effective date of the Fundamental Transaction), equal to the Mandatory Prepayment Amount on the date of such request.

(ix) Notwithstanding the foregoing, no adjustment will be made under this paragraph (c) in respect of (A) the granting of options to employees, officers and directors of the Company pursuant to any stock option plan duly adopted by a majority of the non-employee members of the Board of Directors of the Company or a majority of the members of a committee of non-employee directors established for such purpose, (B) upon the exercise of this Debenture or any other Debenture of this series or of any other series or security issued by the Company in connection with the offer and sale of this Company's securities pursuant to the Purchase Agreement, or (C) upon the exercise of or conversion of any Convertible Securities, options or warrants issued and outstanding on the Original Issue Date, provided such securities have not been amended since the date of the Purchase Agreement, or (D) acquisitions or strategic investments, the primary purpose of which is not to raise capital.

(c) The Company covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock solely for the purpose of issuance upon conversion of the Debentures and payment of interest on the Debentures, each as herein provided, free from preemptive rights or any other actual contingent purchase rights of persons other than the Holders, not less than such number of shares of the Common Stock as shall (subject to any additional requirements of the Company as to reservation of such shares set forth in the Purchase Agreement) be issuable (taking into account the adjustments and restrictions of Section 4(b)) upon the conversion of the outstanding principal amount of the Debentures and payment of interest hereunder. The Company covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly and validly authorized, issued and fully paid, nonassessable and, if the Underlying Shares Registration Statement has been declared effective under the Securities Act, registered for public sale in accordance with such Underlying Shares Registration Statement.

(d) Upon a conversion hereunder the Company shall not be required to issue stock certificates representing fractions of shares of the Common Stock, but may if otherwise permitted, make a cash payment in respect of any final fraction of a share based on the Closing Price at such time. If the Company elects not, or is unable, to make such a cash payment, the Holder shall be entitled to receive, in lieu of the final fraction of a share, one whole share of Common Stock.

(e) The issuance of certificates for shares of the Common Stock on conversion of the Debentures shall be made without charge to the Holders thereof for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificate, provided that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the Holder of such Debentures so converted and the Company shall not be required to issue or deliver such certificates unless or until the person or persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

(f) Any and all notices or other communications or deliveries to be provided by the Holders hereunder, including, without limitation, any Conversion Notice, shall be in writing and delivered personally, by facsimile, sent by a nationally recognized overnight courier service or sent by certified or registered mail, postage prepaid, addressed to the Company, at the address set forth above, facsimile number 000-000-0000, Attn: Xxxx Xxxxxxxxxxx, with a copy to Clark, Wilson, Attn: Xxxxxxx Xxxxxx, facsimile number 000-000-0000 or such other address or facsimile number as the Company may specify for such purposes by notice to the Holders delivered in accordance with this Section. Any and all notices or other communications or deliveries to be provided by the Company hereunder shall be in writing and delivered personally, by facsimile, sent by a nationally recognized

overnight courier service or sent by certified or registered mail, postage prepaid, addressed to each Holder at the facsimile telephone number or address of such Holder appearing on the books of the Company, or if no such facsimile telephone number or address appears, at the principal place of business of the Holder. Any notice or other communication or deliveries hereunder shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile telephone number specified in this Section prior to 5:30 p.m. (New York City time), (ii) the date after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile telephone number specified in this Section later than 5:30 p.m. (New York City time) on any date and earlier than 11:59 p.m. (New York City time) on such date, (iii) four days after deposit in the United States mail, (iv) the Business Day following the date of mailing, if sent by nationally recognized overnight courier service, or (v) upon actual receipt by the party to whom such notice is required to be given.

The failure of the Company or the Holder to insist upon strict adherence to any term of this Debenture on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Debenture. Any waiver must be in writing.

Section 12. If any provision of this Debenture is invalid, illegal or unenforceable, the balance of this Debenture shall remain in effect, and if any provision is inapplicable to any person or circumstance, it shall nevertheless remain applicable to all other persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder violates applicable laws governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum permitted rate of interest. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of or interest on this Debenture as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this indenture, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefits or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impeded the execution of any power herein granted to the Holder, but will suffer and permit the execution of every such as though no such law has been enacted.

Section 13. Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day.

The Registration Statement shall be on Form S-3 (unless the Company is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall be on another appropriate form in accordance herewith) and shall contain (unless otherwise directed by the Holders and except to the extent the Company determines that modifications thereto are required under applicable law) substantially the "Plan of Distribution" attached hereto as Annex A. Subject to the terms of this Agreement, the Company shall use its best efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as possible after the filing thereof, but in any event prior to the applicable Effectiveness Date, and shall use its best efforts to keep such Registration Statement continuously effective under the Securities Act until the date which is two years after the date that such Registration Statement is declared effective by the Commission or such earlier date when all Registrable Securities covered by such Registration Statement have been sold or may be sold without volume restrictions pursuant to Rule 144(k) as determined by the counsel to the Company pursuant to a written opinion letter to such effect, addressed and acceptable to the Company's transfer agent and the affected Holders (the "Effectiveness Period").

(b) If: (i) a Registration Statement is not filed on or prior to its Filing Date (if the Company files a Registration Statement without affording the Holders the opportunity to review and comment on the same as required by Section 3(a), the Company shall not be deemed to have satisfied clause (i)), or (ii) the Company fails to file with the Commission a request for acceleration in accordance with Rule 461 promulgated under the Securities Act, within five (5) Trading Days of the date that the Company is notified (orally or in writing, whichever is earlier) by the Commission that a Registration Statement will not be "reviewed," or not subject to further review, or (iii) prior to its Effectiveness Date, the Company fails to file a pre-effective amendment and otherwise respond in writing to comments made by the Commission in respect of such Registration Statement within 15 Trading Days after the receipt of comments by or notice from the Commission that such amendment is required in order for a Registration Statement to be declared effective, or (iv) a Registration Statement filed or required to be filed hereunder is not declared effective by the Commission by its Effectiveness Date, or (v) after the Effectiveness Date, a Registration Statement ceases for any reason to remain continuously effective as to all Registrable Securities for which it is required to be effective, or the Holders are not permitted to utilize the Prospectus therein to resell such Registrable Securities for 7 consecutive Trading Days or in any individual case an aggregate of 20 Trading Days during any 12 month period (which need not be consecutive Trading Days) (any such failure or breach being referred to as an "Event", and for purposes of clause (i) or (iv) the date on which such Event occurs, or for purposes of clause (ii) the date on which such five Trading Day period is exceeded, or for purposes of clause (iii) the date which such 15 Trading Day period is exceeded, or for purposes of

clause (v) the date on which such 7 or 20 Trading Day period, as applicable, is exceeded being referred to as "Event Date"), then, on each such Event Date and every monthly anniversary thereof until the applicable Event is cured, the Company shall pay to each Holder an amount in cash, as liquidated damages and not as a penalty, equal to 2.0% per month of (i) the Subscription Amount paid by such Holder pursuant to the Purchase Agreement for Securities then held by such Holder, and (ii) if the Warrants are "in the money" and then held by the Holder, the value of any outstanding Warrants (valued at the difference between the average Closing Price during the applicable month and the Exercise Price multiplied by the number of shares of Common Stock the Warrants are exercisable into). If the Company fails to pay any liquidated damages pursuant to this Section in full within seven days after the date payable, the Company will pay interest thereon at a rate of 18% per annum (or such lesser maximum amount that is permitted to be paid by applicable law) to the Holder, accruing daily from the date such liquidated damages are due until such amounts, plus all such interest thereon, are paid in full. The liquidated damages pursuant to the terms hereof shall apply on a pro-rata basis for any portion of a month prior to the cure of an Event. Notwithstanding anything herein to the contrary, if an Event occurs and such Event is caused, directly or indirectly, solely by a Holder's failure to provide the Company, upon written request by the Company, such Holder's beneficial ownership of the Common Stock or information regarding the control person(s) of the Holder, the Event Date shall be tolled to the extent such information is not provided within three (3) Trading Days of its request.

3. Registration Procedures

In connection with the Company's registration obligations hereunder, the Company shall:

(a) Not less than three (3) Trading Days prior to the filing of each Registration Statement or any related Prospectus or any amendment or supplement thereto (excluding any document that would be incorporated or deemed incorporated therein by reference), the Company shall, (i) furnish to each Holder copies of all such documents proposed to be filed, which documents (other than those incorporated or deemed to be incorporated by reference) will be subject to the review of such Holders, and (ii) cause its officers and directors, counsel and independent certified public accountants to respond to such inquiries as shall be necessary, in the reasonable opinion of respective counsel to conduct a reasonable investigation within the meaning of the Securities Act. The Company shall not file the Registration Statement or any such Prospectus or any amendments or supplements thereto to which the Holders of a majority of the Registrable Securities shall reasonably and in good faith object, provided, the Company is notified of such objection in writing no later than three (3) Trading Days after the Holders have been so furnished copies of such documents.

(b) (i) Prepare and file with the Commission such amendments, including post-effective amendments, to a Registration Statement and the Prospectus used in connection therewith as may be necessary to keep a Registration Statement continuously effective as to the applicable Registrable Securities for the Effectiveness Period and prepare and file

with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities; (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement), and as so supplemented or amended to be filed pursuant to Rule 424; (iii) respond as promptly as reasonably possible, and in any event within 15 Trading Days, to any comments received from the Commission with respect to a Registration Statement or any amendment thereto and as promptly as reasonably possible provide the Holders true and complete copies of all correspondence from and to the Commission relating to a Registration Statement; and (iv) comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by a Registration Statement during the applicable period in accordance (subject to the terms of this Agreement) with the intended methods of disposition by the Holders thereof set forth in such Registration Statement as so amended or in such Prospectus as so supplemented.

(c) If during the Effectiveness Period, the number of Registrable Securities at any time exceeds 75% of the number of shares of Common Stock then registered in a Registration Statement, then the Company shall file as soon as reasonably practicable but in any case prior to the applicable Filing Date, an additional Registration Statement covering the resale of by the Holders of not less than 200% of the number of such Registrable Securities.

(d) Notify the Holders of Registrable Securities to be sold (which notice shall, pursuant to clauses (ii) through (vi) hereof shall be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made) as promptly as reasonably possible (and, in the case of (i)(A) below, not less than five (5) Trading Days prior to such filing) and (if requested by any such Person) confirm such notice in writing no later than one (1) Trading Day following the day (i)(A) when a Prospectus or any Prospectus supplement or post-effective amendment to a Registration Statement is proposed to be filed; (B) when the Commission notifies the Company whether there will be a "review" of such Registration Statement and whenever the Commission comments in writing on such Registration Statement (the Company shall provide true and complete copies thereof and all written responses thereto to each of the Holders); and (C) with respect to a Registration Statement or any post-effective amendment, when the same has become effective; (ii) of any request by the Commission or any other Federal or state governmental authority for amendments or supplements to a Registration Statement or Prospectus or for additional information; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; (v) of the occurrence of any event or passage of time that makes the financial statements included in a Registration Statement ineligible for inclusion therein or any statement made in a Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any

material respect or that requires any revisions to a Registration Statement, Prospectus or other documents so that, in the case of a Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; and (vi) the occurrence or existence of any pending corporate development with respect to the Company that the Company believes may be material and that, in the determination of the Company, makes it not in the best interests of the Company to allow continued availability or the Registration Statement or Prospectus.

(e) Promptly deliver to each Holder, without charge, as many copies of the Prospectus or Prospectuses (including each form of prospectus) and each amendment or supplement thereto as such Persons may reasonably request. Subject to the terms of this Agreement, the Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto.

(f) Use commercially reasonable efforts to register or qualify the resale of such Registrable Securities as required under applicable securities or Blue Sky laws of each State within the United States as any Holder requests in writing, to keep each such registration or qualification (or exemption therefrom) effective during the Effectiveness Period; provided, that the Company shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or subject the Company to any material tax in any such jurisdiction where it is not then so subject.

(g) Cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free, to the extent permitted by the Purchase Agreement, of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holders may request.

(h) Upon the occurrence of any event contemplated by this Section 3, as promptly as reasonably possible, prepare a supplement or amendment, including a post-effective amendment, to a Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither a Registration Statement nor such Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Holders in accordance with clauses (ii) through (vi) of Section 3(d) above to suspend the use of the use of

any Prospectus until the requisite changes to such Prospectus have been made, or the Company otherwise notifies the Holders of its election to suspend the availability of a Registration Statement and Prospectus pursuant to clause (vi) of Section 3(d), then the Holders shall suspend use of such Prospectus. The Company will use its best efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable, except that in the case of suspension of the availability of a Registration Statement and Prospectus pursuant to clause (vi) of Section 3(d), the Company shall not be required to take such action until such time as it shall determine that the continued availability of the Registration Statement and Prospectus is no longer not in the best interests of the Company.

(i) Comply with all applicable rules and regulations of the Commission.

(j) Use its best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment.

(k) The Company may require, at any time prior to the third (3^rd) Trading Day prior to the Filing Date, each Holder to furnish to the Company a statement as to the number of shares of Common Stock beneficially owned by such Holder and, if requested by the Commission, the controlling person thereof, within three (3) Trading days of the Company's request. During any periods that the Company is unable to meet its obligations hereunder with respect to the registration of the Registrable Securities solely because any Holder fails to furnish such information within three (3) Trading Days of the Company's request, any liquidated damages that are accruing at such time shall be tolled and any Event of Default that may otherwise occur solely because of such delay shall be suspended, until such information is delivered to the Company.

4. Registration Expenses. All fees and expenses incident to the performance of or compliance with this Agreement by the Company shall be borne by the Company whether or not any Registrable Securities are sold pursuant to the Registration Statement. The fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (A) with respect to filings required to be made with the Principal Market on which the Common Stock is then listed for trading, and (B) in compliance with applicable state securities or Blue Sky laws (including, without limitation, fees and disbursements of counsel for the Company in connection with Blue Sky qualifications or exemptions of the Registrable Securities and determination of the eligibility of the Registrable Securities for investment under the laws of such jurisdictions as requested by the Holders), (ii) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities and of printing prospectuses requested by the Holders), (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel for the Company, and (v) fees and expenses of all other Persons retained by the Company in connection with the consummation of the transactions contemplated by this Agreement. In addition, the Company shall be responsible for all of its internal expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and expenses incurred in connection with the listing of the Registrable Securities

on any securities exchange as required hereunder. In no event shall the Company be responsible for any broker or similar commissions or, except to the extent provided for in the Transaction Documents, any legal fees or other costs of the Holders.

5. Indemnification

(a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless each Holder, the officers, directors, agents, brokers (including brokers who offer and sell Registrable Securities as principal as a result of a pledge or any failure to perform under a margin call of Common Stock), investment advisors and employees of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, costs of preparation and reasonable attorneys' fees) and expenses (collectively, "Losses"), as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in a Registration Statement, any Prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that (1) such untrue statements or omissions or alleged untrue statements or omissions are based upon information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder's proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use in a Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto or (2) in the case of an occurrence of an event of the type specified in Section 3(d)(ii)-(vi), the use by such Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing that the Prospectus is outdated or defective and prior to the receipt by such Holder of the Advice contemplated in Section 6(e). The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding arising from or in connection with the transactions contemplated by this Agreement of which the Company is aware.

(b) Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses (as determined by a court of competent jurisdiction in a final judgment not subject to appeal or review) arising out of or

based upon any untrue statement of a material fact contained in any Registration Statement, any Prospectus, or any form of prospectus, or in any amendment or supplement thereto, or arising out of or based upon: (i) such Holder's failure to comply with the prospectus delivery requirements of the Securities Act or (ii) any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading to the extent, but only to the extent, such untrue statement or omission is contained in any information so furnished in writing by such Holder to the Company specifically for inclusion in such Registration Statement or such Prospectus or to the extent that (1) such untrue statements or omissions are based upon information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent such information relates to such Holder or such Holder's proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use in the Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto or (2) in the case of an occurrence of an event of the type specified in Section 3(d)(ii)-(vi), the use by such Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing that the Prospectus is outdated or defective and prior to the receipt by such Holder of the Advice contemplated in Section 6(e). In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation.

(c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an "Indemnified Party"), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the "Indemnifying Party") in writing, and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that such failure shall have prejudiced the Indemnifying Party.

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such fees and expenses; or (2) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a material conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and the expense of one such counsel for each Holder shall be at the expense of the Indemnifying Party). The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be

unreasonably withheld. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

Subject to the terms of this Agreement, all fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within ten Trading Days of written notice thereof to the Indemnifying Party (regardless of whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder).

(d) Contribution. If a claim for indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party (by reason of public policy or otherwise), then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in Section 5(c), any reasonable attorneys' or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 5(d), no Holder shall be required to contribute, in the aggregate, any amount in excess of the amount by which the proceeds actually received by such Holder from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

The indemnity and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties.

6. Miscellaneous

(a) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the same shall be in writing and signed by the Company and all of the Holders of the then outstanding Registrable Securities. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders and that does not directly or indirectly affect the rights of other Holders may be given by Holders of all of the Registrable Securities to which such waiver or consent relates; provided, however, that the provisions of this sentence may not be amended, modified, or supplemented except in accordance with the provisions of the immediately preceding sentence.

(b) No Inconsistent Agreements. Neither the Company nor any of its subsidiaries has entered, as of the date hereof, nor shall the Company or any of its subsidiaries, on or after the date of this Agreement, enter into any agreement with respect to its securities, that would have the effect of impairing the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. Except as and to the extent specified in Schedule 6(b) hereto, neither the Company nor any of its subsidiaries has previously entered into any agreement granting any registration rights with respect to any of its securities to any Person that have not been satisfied in full.

(c) No Piggyback on Registrations. Except as and to the extent specified in Schedule 6(c) hereto, neither the Company nor any of its security holders (other than the Holders in such capacity pursuant hereto) may include securities of the Company in the Registration Statement other than the Registrable Securities, and the Company shall not after the date hereof enter into any agreement providing any such right to any of its security holders.

(d) Compliance. Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it in connection with sales of Registrable Securities pursuant to the Registration Statement.

(e) Discontinued Disposition. Each Holder agrees by its acquisition of such Registrable Securities that, upon receipt of a notice from the Company of the occurrence of any event of the kind described in Sections 3(d)(ii), (iii) or (vi), such Holder will forthwith discontinue disposition of such Registrable Securities under a Registration Statement until such Holder's receipt of the copies of the supplemented Prospectus and/or amended Registration Statement contemplated by Section 3(h), or until it is advised in writing (the "Advice") by the Company that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings

Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, borough of Manhattan, for the adjudication of any dispute hereunder or in connection

Plan of Distribution

The selling stockholders and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. The selling stockholders may use any one or more of the following methods when selling shares:

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;
purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
an exchange distribution in accordance with the rules of the applicable exchange;
privately negotiated transactions;
settlement of short sales
broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;
a combination of any such methods of sale; and
any other method permitted pursuant to applicable law.

The selling stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus. Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling stockholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved.

The selling stockholder may from time to time pledge or grant a security interest in some or all of the Shares or common stock or Warrant owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of selling stockholders to

include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

The selling stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. The selling stockholders have informed the Company that none of them have any agreement or understanding, directly or indirectly, with any person to distribute the common stock.

The Company is required to pay all fees and expenses incurred by the Company incident to the registration of the shares. The Company has agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

EXHIBIT C

NEITHER THIS SECURITY NOR THE SECURITIES INTO WHICH THIS SECURITY IS EXERCISABLE HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THIS SECURITY AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY SUCH SECURITIES

STOCK PURCHASE WARRANT

To Purchase __________ Shares of Common Stock of

SmarTire Systems, Inc.

THIS STOCK PURCHASE WARRANT CERTIFIES that, for value received, _____________ (the "Holder"), is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after May 19, 2003 (the "Initial Exercise Date") and, subject to Section 3(e), on or prior to the close of business on the fifth (5^th) anniversary of the Initial Exercise Date (the "Termination Date") but not thereafter, to subscribe for and purchase from SmarTire Systems, Inc., a corporation incorporated in the Yukon Territory (the "Company"), up to ____________ shares (the "Warrant Shares") of Common Stock, no par value per share, of the Company (the "Common Stock"). The purchase price of one share of Common Stock (the "Exercise Price") under this Warrant shall be $0.2645, subject to adjustment hereunder. The Exercise Price and the number of Warrant Shares for which the Warrant is exercisable shall be subject to adjustment as provided herein. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Agreement (the "Purchase Agreement"), dated May 15, 2003, between the Company and the investors signatory thereto.

1. Title to Warrant. Prior to the Termination Date and subject to compliance with applicable laws and Section 7 of this Warrant, this Warrant and all rights hereunder are transferable, in whole or in part, at the office or agency of the Company by the Holder in person or by duly authorized attorney, upon surrender of this Warrant together with the Assignment Form annexed hereto properly endorsed. The transferee shall sign an investment letter in form and substance reasonably satisfactory to the Company.

2. Authorization of Shares. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant in accordance with the terms of this Warrant, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

3. Exercise of Warrant.

(a) Exercise of the purchase rights represented by this Warrant may be made at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company of a duly executed facsimile copy of the Notice of Exercise Form annexed hereto (or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of such Holder appearing on the books of the Company); provided, however, within five (5) Trading Days of the date said Notice of Exercise is delivered to the Company, the Holder shall have surrendered this Warrant to the Company and the Company shall have received payment of the aggregate Exercise Price of the shares thereby purchased by wire transfer or cashier's check drawn on a United States bank. Certificates for shares purchased hereunder shall be delivered to the Holder within the earlier of (i) five (5) Trading Days after the date on which the Notice of Exercise shall have been delivered by facsimile copy or (ii) three (3) Trading Days from the delivery to the Company of the Notice of Exercise Form by facsimile copy, surrender of this Warrant and payment of the aggregate Exercise Price as set forth above ("Warrant Share Delivery Date"); provided, however, in the event the Warrant is not surrendered or the aggregate Exercise Price is not received by the Company within five (5) Trading Days after the date on which the Notice of Exercise shall be delivered by facsimile copy, the Warrant Share Delivery Date shall be extended to the extent such five (5) Trading Day period is exceeded. This Warrant shall be deemed to have been exercised on the date the Notice of Exercise is delivered to the Company by facsimile copy. The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised by payment to the Company of the Exercise Price and all taxes required to be paid by the Holder, if any, pursuant to Section 5 prior to the issuance of such shares, have been paid. If the Company fails to deliver to the Holder a certificate or certificates representing the Warrant Shares pursuant to this Section 3(a) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise. In addition to any other rights available to the Holder, if the Company fails to

deliver to the Holder a certificate or certificates representing the Warrant Shares pursuant to an exercise by the third (3^rd) Trading Day after the Warrant Share Delivery Date, and if after such third Trading Day the Holder is required by its broker to purchase (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a "Buy-In"), then the Company shall (1) pay in cash to the Holder the amount by which (x) the Holder's total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (B) the price at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall limit a Holder's right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company's failure to timely deliver certificates representing shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

(b) If this Warrant shall have been exercised in part, the Company shall, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver to Holder a new Warrant evidencing the rights of Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

(c) Notwithstanding anything herein to the contrary, in no event shall the Holder be permitted to exercise this Warrant for Warrant Shares to the extent that (i) the number of shares of Common Stock beneficially owned by such Holder, together with any affiliate thereof (other than Warrant Shares issuable upon exercise of this Warrant) plus (ii) the number of Warrant Shares issuable upon exercise of this Warrant, would be equal to or exceed 4.99% of the number of shares of Common Stock then issued and outstanding, including shares issuable upon exercise of this Warrant held by such Holder after application of this Section 3(c). As used herein, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder. To the extent that the limitation contained in this Section 3(c) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder) and of which a portion of this Warrant is exercisable shall be in the sole discretion of such Holder, and the submission of a Notice of Exercise shall be deemed to be such Holder's determination of whether this Warrant is exercisable

(in relation to other securities owned by such Holder) and of which portion of this Warrant is exercisable, in each case subject to such aggregate percentage limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination. Nothing contained herein shall be deemed to restrict the right of a Holder to exercise this Warrant into Warrant Shares at such time as such exercise will not violate the provisions of this Section 3(c). The provisions of this Section 3(c) may be waived by the Holder upon, at the election of the Holder, not less than 61 days' prior notice to the Company, and the provisions of this Section 3(c) shall continue to apply until such 61^st day (or such later date, as determined by the Holder, as may be specified in such notice of waiver). No exercise of this Warrant in violation of this Section 3(c) but otherwise in accordance with this Warrant shall affect the status of the Warrant Shares as validly issued, fully-paid and nonassessable.

(d) If at any time after one year from the date of issuance of this Warrant there is no effective Registration Statement registering the resale of the Warrant Shares by the Holder, this Warrant may also be exercised at such time by means of a "cashless exercise" in which the Holder shall be entitled to receive a certificate for the number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) = the Closing Price on the Trading Day preceding the date of such election;

(B) = the Exercise Price of the Warrants, as adjusted; and

(X) = the number of Warrant Shares issuable upon exercise of the Warrants in accordance with the terms of this Warrant.

(e) In the event that the original Holder of this Warrant, or its successors and assigns, defaults on its obligation to fund its respective Subscription Amount at either the Second Closing or Third Closing, the number of Warrant Shares issuable hereunder shall be reduced by an amount equal to the original number of Warrant Shares issuable hereunder multiplied by the fraction of which the numerator is the Subscription Amount defaulted on by the original holder, or its successors and assigns, and the denominator is the aggregate Subscription Amounts of the original Holder.

4. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which Holder would otherwise be entitled to purchase upon such exercise, the Company shall pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price.

5. Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event certificates for Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached

hereto duly executed by the Holder; and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto.

6. Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

7. Transfer, Division and Combination.

(a) Subject to compliance with any applicable securities laws and the conditions set forth in Sections 1 and 7(f) hereof and to the provisions of Section 4.1 of the Purchase Agreement, this Warrant and all rights hereunder are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. A Warrant, if properly assigned, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

(b) This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 7(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice.

(c) The Company shall prepare, issue and deliver at its own expense (other than transfer taxes) the new Warrant or Warrants under this Section 7.

(d) The Company agrees to maintain, at its aforesaid office, books for the registration and the registration of transfer of the Warrants.

(e) If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this Warrant shall not be registered pursuant to an effective registration statement under the Securities Act and under applicable state securities or blue sky laws, the Company may require, as a condition of allowing such transfer (i) that the Holder or transferee of this Warrant, as the case may be, furnish to the Company a written opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that such transfer may be made without registration under the Securities Act and under applicable state securities or blue sky laws, (ii) that the holder or transferee execute and deliver to the

Company an investment letter in form and substance acceptable to the Company and (iii) that the transferee be an "accredited investor" as defined in Rule 501(a) promulgated under the Securities Act.

8. No Rights as Shareholder until Exercise. This Warrant does not entitle the Holder to any voting rights or other rights as a shareholder of the Company prior to the exercise hereof. Upon the surrender of this Warrant and the payment of the aggregate Exercise Price (or by means of a cashless exercise), the Warrant Shares so purchased shall be and be deemed to be issued to such Holder as the record owner of such shares as of the close of business on the later of the date of such surrender or payment.

9. Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

10. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall be a Saturday, Sunday or a legal holiday, then such action may be taken or such right may be exercised on the next succeeding day not a Saturday, Sunday or legal holiday.

11. Adjustments of Exercise Price and Number of Warrant Shares; Stock Splits, etc. The number and kind of securities purchasable upon the exercise of this Warrant and the Exercise Price shall be subject to adjustment from time to time upon the happening of any of the following. In case the Company shall (i) pay a dividend in shares of Common Stock or make a distribution in shares of Common Stock to holders of its outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares, (iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, or (iv) issue any shares of its capital stock in a reclassification of the Common Stock, then the number of Warrant Shares purchasable upon exercise of this Warrant immediately prior thereto shall be adjusted so that the Holder shall be entitled to receive the kind and number of Warrant Shares or other securities of the Company which it would have owned or have been entitled to receive had such Warrant been exercised in advance thereof. Upon each such adjustment of the kind and number of Warrant Shares or other securities of the Company which are purchasable hereunder, the Holder shall thereafter be entitled to purchase the number of Warrant Shares or other securities resulting from such adjustment at an Exercise Price per Warrant Share or other security obtained by multiplying the Exercise Price in effect immediately prior to such adjustment by the number of Warrant Shares purchasable pursuant hereto immediately prior to such adjustment and dividing by the number of Warrant Shares or other securities of the Company resulting from such adjustment. An adjustment made pursuant to this paragraph shall become effective immediately after the effective date of such event retroactive to the record date, if any, for such event.

12. Reorganization, Reclassification, Merger, Consolidation or Disposition of Assets. In case the Company shall reorganize its capital, reclassify its capital stock, consolidate or merge with or into another corporation (where the Company is not the surviving corporation or where there is a change in or distribution with respect to the Common Stock of the Company), or sell, transfer or otherwise dispose of all or substantially all its property, assets or business to another corporation and, pursuant to the terms of such reorganization, reclassification, merger, consolidation or disposition of assets, shares of common stock of the successor or acquiring corporation, or any cash, shares of stock or other securities or property of any nature whatsoever (including warrants or other subscription or purchase rights) in addition to or in lieu of common stock of the successor or acquiring corporation ("Other Property"), are to be received by or distributed to the holders of Common Stock of the Company, then the Holder shall have the right thereafter to receive, at the option of the Holder, (a) upon exercise of this Warrant, the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and Other Property receivable upon or as a result of such reorganization, reclassification, merger, consolidation or disposition of assets by a Holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such event, or (b) cash equal to the value of this Warrant as determined in accordance with the Black-Sholes option pricing formula. In case of any such reorganization, reclassification, merger, consolidation or disposition of assets, the successor or acquiring corporation (if other than the Company) shall expressly assume the due and punctual observance and performance of each and every covenant and condition of this Warrant to be performed and observed by the Company and all the obligations and liabilities hereunder, subject to such modifications as may be deemed appropriate (as determined in good faith by resolution of the Board of Directors of the Company) in order to provide for adjustments of Warrant Shares for which this Warrant is exercisable which shall be as nearly equivalent as practicable to the adjustments provided for in this Section 12. For purposes of this Section 12, "common stock of the successor or acquiring corporation" shall include stock of such corporation of any class which is not preferred as to dividends or assets over any other class of stock of such corporation and which is not subject to redemption and shall also include any evidences of indebtedness, shares of stock or other securities which are convertible into or exchangeable for any such stock, either immediately or upon the arrival of a specified date or the happening of a specified event and any warrants or other rights to subscribe for or purchase any such stock. The foregoing provisions of this Section 12 shall similarly apply to successive reorganizations, reclassifications, mergers, consolidations or disposition of assets.

13. Voluntary Adjustment by the Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

14. Notice of Adjustment. Whenever the number of Warrant Shares or number or kind of securities or other property purchasable upon the exercise of this Warrant or the Exercise Price is adjusted, as herein provided, the Company shall give notice thereof to the Holder, which notice shall state the number of Warrant Shares (and other securities or property) purchasable upon the exercise of this Warrant and the Exercise Price of such Warrant Shares (and other securities or property) after such adjustment, setting forth a brief statement of the facts requiring such adjustment and setting forth the computation by which such adjustment was made.

15. Notice of Corporate Action. If at any time:

(a) the Company shall take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or other distribution, or any right to subscribe for or purchase any evidences of its indebtedness, any shares of stock of any class or any other securities or property, or to receive any other right, or

(b) there shall be any capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company or any consolidation or merger of the Company with, or any sale, transfer or other disposition of all or substantially all the property, assets or business of the Company to, another corporation or,

then, in any one or more of such cases, the Company shall give to Holder (i) at least 20 days' prior written notice of the date on which a record date shall be selected for such dividend, distribution or right or for determining rights to vote in respect of any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, liquidation or winding up, and (ii) in the case of any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up, at least 20 days' prior written notice of the date when the same shall take place. Such notice in accordance with the foregoing clause also shall specify (i) the date on which any such record is to be taken for the purpose of such dividend, distribution or right, the date on which the holders of Common Stock shall be entitled to any such dividend, distribution or right, and the amount and character thereof, and (ii) the date on which any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up is to take place and the time, if any such time is to be fixed, as of which the holders of Common Stock shall be entitled to exchange their Warrant Shares for securities or other property deliverable upon such disposition, dissolution, liquidation or winding up. Each such written notice shall be sufficiently given if addressed to Holder at the last address of Holder appearing on the books of the Company and delivered in accordance with Section 17(d).

16. Authorized Shares. The Company covenants that during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Principal Market upon which the Common Stock may be listed.

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of

incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (a) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (b) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant, and (c) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be necessary to enable the Company to perform its obligations under this Warrant.

Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

17. Miscellaneous.

(a) Jurisdiction. This Warrant shall constitute a contract under the laws of New York, without regard to its conflict of law, principles or rules.

(b) Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, will have restrictions upon resale imposed by state and federal securities laws.

(c) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice Holder's rights, powers or remedies, notwithstanding all rights hereunder terminate on the Termination Date. If the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys' fees, including those of appellate proceedings, incurred by Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

(d) Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in accordance with the notice provisions of the Purchase Agreement.

(e) Limitation of Liability. No provision hereof, in the absence of any affirmative action by Holder to exercise this Warrant or purchase Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of

Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

(f) Remedies. Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate.

(g) Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of all Holders from time to time of this Warrant and shall be enforceable by any such Holder or holder of Warrant Shares.

(h) Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

(i) Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

(j) Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

Dear Sirs:

Re: SmarTire Systems Inc. - Private Placement of 7% Convertible Debentures and Warrants

This opinion is furnished to you pursuant to the Securities Purchase Agreement (the "Purchase Agreement") by and among the purchasers signatory thereto (the "Purchasers") and SmarTire Systems Inc., a Yukon corporation (the "Company"), dated as of even date herewith (the "Purchase Agreement"), which provides for the issuance and sale by the Company of up to $2,800,000 principal amount of Debentures and Warrants to purchase shares of the Company's Common Stock. All terms used herein have the meanings defined for them in the Purchase Agreement unless otherwise defined herein.

We have acted as counsel for the Company in connection with the preparation of the following documents (collectively, the "Transaction Documents"):

(a) the Purchase Agreement;

(b) the Debentures;

(d) the Escrow Agreement dated as of even date herewith by and among the Company and the Purchasers; and

(e) the Registration Rights Agreement dated as of even date herewith by and among the Company and the Purchasers.

We have examined such statutes, public and corporate records and such documents and certificates of officers of the Company and others and considered such questions of law and conducted such other investigations as we have deemed relevant or necessary as a basis for the opinions expressed herein.

We have assumed the genuineness and authenticity of all signatures on all documents submitted or presented to us, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of documents submitted to us as certified, telecopied, conformed or photostatic copies. We have also assumed, without verification, the legal capacity of each individual who has executed documents or instruments in connection with the transaction contemplated hereby.

We have also assumed, without verification: (i) that each Purchaser is an existing limited partnership or body corporate, as the case may be, and has the power and authority to enter into and perform the Transaction Documents to which such Purchaser is a party; (ii) the due authorization, execution and delivery by such Purchaser of such Transaction Documents; (iii) that each of such Transaction Documents constitutes legal, valid and binding obligations of such Purchaser, enforceable in accordance with its respective terms; and (iv) that the representations and warranties made by each Purchaser in the Transaction Documents and pursuant thereto are true and correct.

With reference to the opinion set forth in paragraph 6, we have assumed that the laws of the State of New York respecting the validity and binding nature of contracts are substantially similar to the laws of the Province of British Columbia.

As used in this opinion, the expression "to our knowledge" refers to the current actual knowledge of the lawyers of this firm who have worked on matters for the Company solely in connection with the Transaction Documents and the transactions contemplated thereby, and without any independent investigation of any underlying facts or situations.

In expressing the opinion set forth in paragraph 1, we have relied exclusively upon a Certificate of Status dated May 9, 2003 issued by the Yukon Registrar of Corporations in respect of the Company (a copy of such certificate having been delivered to you).

In expressing the opinion set forth in paragraph 11 with respect to the issued and outstanding common shares in the capital of the Company, we have relied entirely on the advice of Pacific Corporate Trust Company in its capacity as the Company's registrar and transfer agent.

The opinions expressed herein are subject to the following qualifications:

(a) a judgment in money rendered by a court in Canada must be awarded in Canadian currency and such judgment may be based on a rate of exchange on a day other than the day of payment of such judgment;

(b) the validity, binding effect and enforceability of the Transaction Documents may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to creditors' rights generally;

(c) the enforceability of the Transaction Documents and the rights and remedies set out therein may be limited by general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity) and no opinion is given as to any specific remedy that may be granted, imposed or rendered. The limitation by general principles of equity include principles:

(i) governing the availability of specific performance, injunctive relief or other equitable remedies;

(ii) affording equitable defences such as waiver, laches and estoppel against a party seeking enforcement;

(iii) requiring good faith and fair dealing in the performance and enforcement of a contract by the party seeking its enforcement;

(iv) requiring reasonableness in the performance and enforcement of an agreement by the party seeking enforcement of the contract;

(v) requiring consideration of the materiality of a party's breach and the consequences of the breach to the party seeking enforcement;

(vi) requiring consideration of the enforceability or impossibility of performance at the time of attempted enforcement; and

(vii) affording defences based upon the unconscionability of the enforcing party's conduct after the parties have entered into the contract;

(d) claims may become statute barred by the Limitation Act (British Columbia);

(e) the ability to recover a claim for certain costs or expenses may be subject to judicial discretion;

(f) under the Court Order Interest Act (British Columbia), interest after judgment may be limited to a rate which is less than the rate specified in the Debenture;

(g) our opinions are subject to the effect of generally applicable rules of law that:

(i) limit or affect the enforcement of provisions of a contract that purport to require waiver of the obligations of good faith, fairness in dealing, diligence and reasonableness;

(ii) limit the right of a creditor to use force or cause a breach of the peace in enforcing rights, or limit the liability of a creditor for obligations incurred or assumed by such creditor;

(iii) limit the enforceability of provisions releasing, exculpating or exempting a party from, or requiring indemnification of a party for, liability for its own action or inaction, to the extent the action or inaction involved gross negligence, recklessness, wilful misconduct or unlawful conduct; and

(iv) may, where less than all of a contract may be unenforceable, limit the enforceability of the balance of the contract to circumstances in which the unenforceable portion is not an essential part of the agreed exchange;

(h) whenever our opinion herein with respect to the existence or absence of facts or circumstances is qualified by the phrase "to our knowledge" or similar language, it is intended to indicate that during the course of our representation of the Company, no information has come to our attention which would give us actual knowledge of the existence of such facts or circumstances. However, except to the extent expressly set forth herein, we have not undertaken any special or independent investigation to determine the existence or absence of such facts or circumstances, and no inference as to our knowledge of the existence of such facts or circumstances should be drawn merely from our representation of the Company;

(i) the provisions for the payment of interest in any of the Transaction Documents may not be enforceable if those provisions provide for the receipt of interest by any Purchaser at a "criminal rate" within the meaning of section 347 of the Criminal Code (Canada), reproduced in Schedule "A" hereto; and

(j) this opinion is restricted to the matters expressly referred to herein and no opinion is intended to be given or to be implied with respect to any other matter.

Based and relying upon and subject to the foregoing, we are of the opinion that at the date hereof:

1. The Company has been continued and is validly subsisting under the laws of the Yukon and is, according to the records of the office of the Registrar of Corporations for the Yukon, in good standing with respect to the filing of annual returns.

2. The Company has all requisite corporate power and authority to carry on its business and to own, lease and operate its properties and assets as described in the Company's SEC Documents. To our knowledge, Schedule 3.1(a) to the Purchase Agreement constitutes a true and complete list of the Company's Subsidiaries, and the Company does not own more than fifty percent (50%) of the outstanding capital stock of or control any other business entity.

3. The Company has the requisite corporate power and authority to enter into and perform its obligations under the Transaction Documents and to issue the Debentures and Warrants and the Underlying Shares.

4. The execution and delivery of the Transaction Documents by the Company and the consummation by it of the transactions contemplated thereby have been duly authorized by all necessary corporate action and no further consent or authorization of the Company or its Board of Directors or shareholders is required.

5. Each of the Transaction Documents has been duly executed and delivered, and the Debentures and Warrants issuable to the Purchasers at the First Closing have been duly executed, issued and delivered by the Company.

6. Each of the Transaction Documents, the Debentures and the Warrants constitutes valid and binding obligations of the Company enforceable against the Company in accordance with their respective terms, absent the application of any usury laws or any laws proscribing a criminal rate of interest in respect of which we express no opinion.

7. The execution, delivery and performance of the Transaction Documents by the Company and the consummation by the Company of the transactions contemplated thereby, including, without limitation, the issuance of the Debentures, the Warrants and the Underlying Shares, do not and will not:

(a) result in a violation of the Company's Articles of Continuance or Bylaws;

(b) conflict with, or constitute a material default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any material agreement, indenture, instrument or any "lock-up", refusal or similar provision of any underwriting or similar agreement to which the Company is a party, other than the Company's agreements with Cornell Capital Partners, LP, TRW, Inc. and TRW Automotive U.S. LLC; or

(c) result in a violation of any federal provincial or state law, rule or regulation applicable to the Company or by which any property or asset of the Company is bound or affected, except for: (i) such violations as would not, individually or in the aggregate, have a Material Adverse Effect, (ii) the shareholder approval requirements set forth in Rule 4350 of the NASDAQ Marketplace Rules, in respect of which we express no opinion, (iii) the New York Fraudulent Practices ("Xxxxxx") Act, General Business Law, Ch. 20, Art. 23-A, in respect of which we express no opinion, and (iv) any usury laws or any laws proscribing a criminal rate of interest in respect of which we express no opinion.

8. To our knowledge, the Company is not in violation of any terms of its Articles of Continuance or Bylaws.

9. The issuance of the Debentures, the Warrants, and the Underlying Shares in accordance with the Purchase Agreement will be exempt from registration under the United States Securities Act of 1933, as amended. When so issued, the Debentures, the Warrants and, upon conversion of the Debentures or exercise of the Warrants in accordance with their respective terms, the Underlying Shares, will be duly and validly issued, fully paid and nonassessable, and free of any liens, encumbrances and preemptive or similar rights contained in the Company's Articles of Continuance or Bylaws or, to our knowledge, in any agreement to which the Company is party.

10. To our knowledge, except as disclosed in Schedules 3.1(j), 3.1(k) and 3.1(v) to the Purchase Agreement, there are no claims, actions, suits, proceedings or investigations pending against the Company or its properties, or against any officer or director of the Company in his or her capacity as such, which individually or in the aggregate, would have a Material Adverse Effect. To our knowledge, the Company is not a party to or subject to the provisions of any order, writ, injunction, judgment or decree of any court or government agency or instrumentality.

11. The authorized capital of the Company consists of 200,000,000 common shares without par value and 20,000 preferred shares, par value CDN$1,000, of which 31,645,693 common shares and no preferred shares are issued and outstanding.

12. In any proceedings undertaken in courts of competent jurisdiction in the Province of British Columbia to enforce and interpret the Transaction Documents governed by the laws of New York, with respect to issues that would be characterised by courts in the Province of British Columbia as contract issues, the courts would, to the extent pleaded and proved, enforce the Transaction Documents governed by the laws of New York in accordance with the laws of New York, except that courts in the Province of British Columbia:

(a) will apply only procedural laws of the Province of British Columbia and may apply laws of mandatory application;

(b) may not enforce an obligation enforceable under the laws of New York where performance of the obligations would be illegal by the law of the place of performance;

(c) may reserve to themselves an inherent power to decline to hear such an action if it is contrary to public policy, as such term is understood under the laws of the Province of British Columbia, for them to do so, or if they are not the proper forum to hear such action, or if concurrent proceedings are being brought elsewhere.

13. Courts of competent jurisdiction in the Province of British Columbia would enforce a final, conclusive and subsisting judgment in personam of the court of New York enforcing the rights of any Purchaser under the Transaction Documents governed by the laws of New York as against the Company if certain criteria are met, including, without limitation the following:

(a) the judgment was for a sum certain in money;

(b) the New York court had jurisdiction over the judgment debtor, as recognized by the courts of the Province of British Columbia and the New York court;

(d) the enforcement of the judgment would be consistent with laws of mandatory application and principles of public policy in the Province of British Columbia;

(e) no new admissible evidence, right of defence relevant to the action accrues or is discovered prior to the rendering of judgment by the courts of the Province of British Columbia;

(f) the enforcement of the judgment would not constitute, directly or indirectly, the enforcement of a foreign revenue, penal or expropriatory laws; and

(g) there has been compliance with the limitations statute of the Province of British Columbia, which requires that an action to enforce a foreign judgment must be commenced within a period of six years of the date of the foreign judgment in the Province of British Columbia.

This opinion may not be relied upon by any person or entity other than the addressees hereof, their successors and their assigns of whom we have notice at the time of the assignment, and this opinion may not be circulated, quoted or otherwise referred to for any purpose other than in connection with the transactions contemplated by the Transaction Documents, in each case, without our prior written consent. We do not undertake to advise you or anyone else of any changes in the opinions expressed herein resulting from changes in law, changes in facts or any other matters that hereafter might occur that did not exist on the date hereof.

Yours truly,

2.3 This Escrow Agreement shall be binding upon and shall inure to the benefit of the permitted successors and permitted assigns of the parties hereto.

2.5 Whenever required by the context of this Escrow Agreement, the singular shall include the plural and masculine shall include the feminine.

The Escrow Agent has acted as legal counsel for Palisades Master Fund, L.P. ("Palisades"), and may continue to act as legal counsel for Palisades, from time to time, notwithstanding its duties as the Escrow Agent hereunder. The Company consents to the Escrow Agent in such capacity as legal counsel for Palisades and waives any claim that such representation represents a conflict of interest on the part of the Escrow Agent. The Company understands that Palisades and the Escrow Agent are relying explicitly on the foregoing provision in entering into this Escrow Agreement.

2.12 The Escrow Agent's responsibilities as escrow agent hereunder shall terminate if the Escrow Agent shall resign by written notice to the Company and the Investors. In the event of any such resignation, the Investors and the Company shall appoint a successor Escrow Agent.

2.13 If the Escrow Agent reasonably requires other or further instruments in connection with this Escrow Agreement or obligations in respect hereto, the necessary parties hereto shall join in furnishing such instruments.

2.14 It is understood and agreed that should any dispute arise with respect to the delivery and/or ownership or right of possession of the documents or the escrow funds held by the Escrow Agent hereunder, the Escrow Agent is authorized and directed in the Escrow Agent's sole discretion (1) to retain in the Escrow Agent's possession without liability to anyone all or any part of said documents or the escrow funds until such disputes shall have been settled either by mutual written agreement of the parties concerned by a final order, decree or judgment or a court of competent jurisdiction after the time for appeal has expired and no appeal has been perfected, but the Escrow Agent shall be under no duty whatsoever to institute or defend any such proceedings or (2) to deliver the escrow funds and any other property and documents held by the Escrow Agent hereunder to a state or Federal court having competent subject matter jurisdiction and located in the City of New York in accordance with the applicable procedure therefor.

2.15 The Company and each Investor agree jointly and severally to indemnify and hold harmless the Escrow Agent and its partners, employees, agents and representatives from any and all claims, liabilities, costs or expenses in any way arising from or relating to the duties or performance of the Escrow Agent hereunder or the transactions contemplated hereby or by the Purchase Agreement other than any such claim, liability, cost or expense to the extent the same shall have been determined by final, unappealable judgment of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Escrow Agent.
