This right of termination shall not affect pending duly issued Put Notices.

ARTICLE V

Other Agreements of the Parties

        Section 5.1    Listing of Common Stock.    The Company shall maintain the listing of the Common Stock on a Principal Market, and as soon as practicable (but in any event prior to the commencement of the Commitment Period) shall list on such Principal Market all of the Put Shares. The Company further agrees, if the Company applies to have the Common Stock traded on any other Principal Market, it will include in such application the issued and issuable Put Shares.

During the Commitment Period, the Company will notify the Investor immediately following each filing by the Company under the Exchange Act. As long as the Investor owns Put Shares, if the Company is not required to file reports pursuant to such sections, it will prepare and furnish to the Investor and make publicly available in accordance with Rule 144(c) promulgated under the Securities Act such information as is required for the Investor to sell the Put Shares under Rule 144 promulgated under the Securities Act. The Company further covenants that it will take such further action as any holder of Put Shares may reasonably request, all to the extent required from time to time to enable such Person to sell such Put Shares without

14

registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including causing its attorneys to render and deliver any legal opinion required in order to permit such Person to sell its Put Shares under Rule 144 upon notice of an intention to sell on Form 144 or other form of notice having a similar effect. Upon the request of any such Person, the Company shall deliver to such Person a written certification of a duly authorized officer as to whether it has complied with such requirements.

        Section 5.3    Legends.    The certificates evidencing the Common Stock to be sold or otherwise issued to the Investor hereunder at any time while a Registration Statement is then effective shall be issued and delivered to the Investor free of restrictive legends of any kind and no instructions or "stop transfer orders," so called, "stock transfer restrictions," or other restrictions have been or shall be given to the Company's transfer agent with respect thereto. Prior to the first Closing, the Company will issue to the transfer agent for its Common Stock (and to any substitute or replacement transfer agent for its Common Stock upon the Company's appointment of any such substitute or replacement transfer agent) instructions to deliver the Put Shares without restrictive legends as required by this Section and shall cause its counsel to deliver to such transfer agent any legal opinion required in order for the transfer agent to deliver shares in such manner.

        Section 5.5    Subsequent Financing; Limitation on Registrations.    (a) From the date of this Agreement through the end of the Commitment Period, other than to the Investor pursuant to this Agreement, the Company agrees to immediately notify the Investor in writing of any offer, sale, grant of any option to purchase or any right to reprice securities, or other disposition of (or announce any offer, sale, grant or any option to purchase or other disposition) any Capital Shares or Capital Shares Equivalents ("Other Financing"). Once the Investor is notified of an Other Financing, if the Other Financing is consummated or publicly announced during a Valuation Period, the Investor, at its sole option, may (i) purchase Put Shares for such Valuation Period (A) at a price equal to the purchase price for the Capital Shares or Capital Shares Equivalents to be issued pursuant to the Other

15

Financing, or (B) at a price equal to the Purchase Price in accordance with this Agreement, (ii) purchase the Capital Shares or Capital Shares Equivalents offered in the Other Financing in an amount equal to the Purchase Price, or (iii) elect not to purchase any Put Shares for such Valuation Period.

In the event the Company offers, sells or issues shares of Common Stock or Common Stock Equivalents at a price that is less than the Purchase Price of the Put Shares, then the Purchase Price shall be adjusted to the price of such shares of Common Stock or Common Stock Equivalents offered, sold or issued in the Other Financing.

        (b)   In furtherance of the restriction contained in Section 5.5(a) above, other than to the Investor or Affiliates thereof, prior to the expiration of the Commitment Period, the Company may not enter into equity line or similar type of financing arrangement or agree to issue any shares of its Common Stock or any Capital Shares Equivalents pursuant to any equity line or similar type of financing, unless otherwise agreed to in writing by the Company and the Investor.

        (e)   The restrictions contained in Section 5.5(a), (b) and (c) shall not apply to (i) the granting of options or warrants that are outstanding on the date hereof and the issuance of Common Stock upon the exercise of such options or warrants outstanding on the date hereof, (ii) the granting of warrants to the Broker in accordance with the Placement Agent Agreement, and the issuance of Common Stock upon the exercise of such warrants, and (iii) the granting of options or warrants to employees, officers and directors of the Company and the issuance of Common Stock upon the exercise of such options or warrants granted under any stock option plan heretofore or hereinafter duly adopted by the Company.

        Section 5.6    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 Put Shares in a manner that would require the registration under the Securities Act of the sale of the Put Shares hereunder to the Investor.

        Section 5.7    Certain Securities Laws Disclosures; Publicity.    The Company shall: (i) within two Business Days of the date of this Agreement, issue a press release acceptable to the Investor disclosing the transactions contemplated hereby, (ii) file with the Commission a Report on Form 8-K disclosing the transactions contemplated hereby within ten Business Days after the date of this Agreement, and

16

(iii) timely file with the Commission a Form D promulgated under the Securities Act.

The Company and the Investor shall consult with each other in issuing any other press releases or otherwise making public statements or filings and other communications with the Commission or any regulatory agency or stock market or trading facility with respect to the transactions contemplated hereby, and neither party shall issue any such press release or otherwise make any such public statement, filings or other communications without the prior written consent of the other, except that if such disclosure is required by law or stock market regulation, in which such case the disclosing party shall promptly provide the other party with prior notice of such public statement, filing or other communication. Notwithstanding the foregoing, the Company shall not publicly disclose the name of the Investor, or include the names of the Investor in any filing with the Commission, or any regulatory agency, trading facility or stock market without the prior written consent of the Investor, except to the extent such disclosure (but not any disclosure as to the controlling Persons thereof) is required by law or stock market regulations, in which case the Company shall provide the Investor with prior notice of such disclosure.

        Section 5.8    Use of Proceeds.    The Company shall use the net proceeds from the sale of the Put Shares for general corporate and working capital purposes and to pay a loan from Xxxxx Fargo Business Credit, Inc. and not to redeem any securities of the Company.

        Section 5.9    Reimbursement.    If the Investor, its shareholders, employees, agents, directors or affiliates, other than by reason of its gross negligence or willful misconduct, becomes involved in any capacity in any action, proceeding or investigation brought by or against any Person, including stockholders of the Company, as a result of the consummation of the transactions contemplated by the Transaction Documents, the Company will reimburse the Investor and such other covered persons for their reasonable legal and other expenses (including the cost of any investigation and 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 Investor 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 Investor 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 Investor and any such affiliate and any such Person. The Company also agrees that neither the Investor 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 in connection with or as a result of the consummation of the Transaction Documents, except to the extent that any losses, claims, damages, liabilities or expenses incurred by the Company result from the gross negligence or willful misconduct of the applicable Investor, Person or entity in connection with the transactions contemplated by this Agreement.

        Section 5.10    Expectations Regarding Put Notices.    Within five days after the Effective Date, the Company must notify the Investor, in writing, as to its reasonable expectations as to the dollar amount it intends to raise during the Commitment Period, if any, through the issuance of Put Notices. Such notification shall constitute only the Company's good faith estimate and shall in no way obligate the Company to raise such amount, or any amount, or otherwise limit its ability to deliver Put Notices. The failure by the Company to comply with this provision can be cured by the Company's notifying the Investor, in writing, at any time as to its reasonable expectations with respect to the current calendar quarter.

        Section 5.11    Purchase Price Adjustment.    If at any time during the Commitment Period the Company or any Subsidiary (with respect to Capital Shares Equivalents) shall offer, sell, grant any option to purchase, or otherwise dispose of (or announce any offer, sale, grant or any option to purchase or other disposition) any of shares of Common Stock or Capital Shares Equivalents at a price

17

that is, at the issuance thereof, or at any later time due to adjustment, reset, additional issuances or otherwise, less than the Purchase Price for any Put Shares (assuming for the purposes hereof that a Put Notice is delivered on the date of the issuance at issue), then, at the option of the Investor for such subsequent Closings as the Investor shall indicate, the Purchase Price shall be adjusted to equal the conversion, exchange or purchase price for such Common Stock or Capital Shares Equivalents (including any reset provisions thereof) at issue. Such adjustment shall be made whenever such Common Stock or Capital Shares Equivalents are issued. If the holder of the Common Stock or Common Stock Equivalent so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights issued in connection with such issuance, be entitled to receive shares of Common Stock at a price less than the Purchase Price (assuming for the purposes hereof that a Put Notice is delivered on the date of the issuance at issue), such issuance shall be deemed to have occurred for less than the Purchase Price. The Company shall notify the Investor in writing, no later than the Trading Day following the issuance of any Common Stock or Common Stock Equivalent subject to this Section 5.11, indicating therein the applicable issuance price, or of applicable reset price, exchange price, conversion price and other pricing terms. The restrictions contained in this Section 5.11 shall not apply to shares of Common Stock issuable upon exercise of any currently outstanding warrants and other outstanding convertible securities of the Company, in each case as and to the extent disclosed in Section 4.3 and Schedule 4.3 (but not as to any amendments or modifications of the terms of such securities after the date of this Agreement, including "back-dated" agreements).

        Section 8.5    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) the same with the same force and effect as if such facsimile signature page were an original thereof.

        Section 8.6    Entire Agreement.    The Transaction Documents, together with the exhibits and schedules thereto contain the entire understanding of the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules.

Investor or, in the case of a waiver, by the party against whom enforcement of any such waiver is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right accruing to it thereafter.

The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Investor. The Investor may not assign this Agreement or any of the rights or obligations hereunder without the consent of the Company; however, this provision shall not limit any Investor's right to transfer Put Shares acquired hereunder or transfer or assign rights under the Registration Rights Agreement.

        Section 8.10    Remedies.    In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, the Investor will be entitled to specific performance of the obligations of the Company under the Transaction Documents. The parties hereto agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of its obligations described in the foregoing sentence and hereby agree to waive in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

        Section 8.11    Severability.    In case any one or more of the provisions of this Agreement shall 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 which shall be a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

        Section 8.12    Headings.    The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof.

        Section 8.13    Fees and Expenses.    Other than the amounts to be delivered to or as directed by the Investor under Section 2.6 and except as otherwise set forth in the Registration Rights Agreement, each party shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement. The Company shall pay all stamp and other taxes and duties levied in connection with the issuance of the Put Shares issuable hereunder.
