(iii) By the Required Investors if any of the conditions set forth in Section 6.1 shall have become incapable of fulfillment, and shall not have been waived by the Required Investors; or

-16-

(iv) By either the Company or the Required Investors if the Closing has not occurred on or prior to April 30, 2002;

provided, however, that, except in the case of clause (i) above, the party seeking to terminate its obligation to effect the Closing shall not then be in breach of any of its representations, warranties, covenants or agreements contained in this Agreement or the other Transaction Documents if such breach has resulted in the circumstances giving rise to such party’s seeking to terminate its obligation to effect the Closing.

(b) In the event of termination by the Company or the Required Investors of their obligations to effect the Closing pursuant to this Section 6.3, written notice thereof shall forthwith be given to the other parties hereto and the obligation of all parties to effect the Closing shall be terminated, without further action by any party. Nothing in this Section 6.3 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or the other Transaction Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or the other Transaction Documents.

7. Covenants and Agreements of the Company.

7.1 Reservation of Common Stock. The Company shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of providing for the exercise of the Warrants, such number of shares of Common Stock as shall from time to time equal the number of shares sufficient to permit the exercise of the Warrants issued pursuant to this Agreement in accordance with their respective terms.

7.2 Reports. The Company will furnish to Investors and/or their assignees holding at least 100,000 shares of Common Stock (each, a “Major Investor”) such information relating to the Company and its Subsidiaries as from time to time may reasonably be requested from the Chief Financial Officer of the Company by such Major Investors; provided, however, that such Major Investors shall hold in confidence any confidential or proprietary information received from the Company and identified as such at the time of disclosure such information and shall use any such confidential or proprietary information solely for the purpose of monitoring and evaluating their investment in the Company and; provided, further, that the Company shall not be required to provide any information to the Major Investors which, if disclosed to such Major Investors pursuant to the terms of this Section 7.2, would, in the good faith judgment of the Company, cause the Company or any Subsidiary to violate the terms of a confidentiality undertaking binding on the Company or such Subsidiary. Each Major Investor acknowledges that it is aware, and that it will advise its representatives who are given access to such information, that the United States securities laws may prohibit a Person who has material, non-public information concerning matters that may be disclosed to it pursuant to this Section 7.2 from purchasing or selling securities of the Company or a company which may be, or may be affiliated with, a party to a business arrangement or proposed business arrangement with the Company or from communicating such information to any other Person under circumstances in which it is reasonably foreseeable that such person is likely to purchase or sell such securities. The Company shall not disclose material nonpublic information to any Investor, or to advisors to

-17-

or representatives of any Investor, unless prior to disclosure of such information the Company identifies such information as being material nonpublic information and provides the Investor, such advisors and representatives with the opportunity to accept or refuse to accept such material nonpublic information for review.

7.3 No Conflicting Agreements. The Company will not take any action, enter into any agreement or make any commitment that would conflict or interfere in any material respect with the obligations to the Investors under the Transaction Documents.

7.4 Compliance with Laws. The Company will comply in all material respects with all applicable laws, rules, regulations, orders and decrees of all governmental authorities.

7.5 Listing of Underlying Shares and Related Matters. Promptly following the date hereof, the Company shall take all necessary action to cause the Shares and the Warrant Shares to be approved for listing on the Nasdaq National Market System no later than the Closing Date. Further, if the Company applies to have its Common Stock or other securities traded on any other principal stock exchange or market, it shall include in such application the Shares and the Warrant Shares and will take such other action as is necessary to cause such Common Stock to be so listed. The Company will use commercially reasonable efforts to continue the listing and trading of its Common Stock on Nasdaq and, in accordance, therewith, will use commercially reasonable efforts to comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of such exchange, as applicable.

7.6 Termination of Covenants. The provisions of Sections 7.2, 7.3 and 7.4 shall terminate and be of no further force and effect upon the earlier of (i) the mutual consent of the Company and the Required Investors or (ii) the date on which the Company’s obligations under the Registration Rights Agreement to register of maintain the effectiveness of any registration covering the Registrable Securities (as such term is defined in the Registration Rights Agreement) shall terminate.

8. Survival and Indemnification.

8.1 Survival. All representations, warranties, covenants and agreements contained in this Agreement shall be deemed to be representations, warranties, covenants and agreements as of the date hereof and shall survive the execution and delivery of this Agreement for a period of eighteen months from the Closing Date; provided, however, that the provisions contained in Section 7 hereof shall survive in accordance therewith.

8.2 Indemnification. The Company agrees to indemnify and hold harmless, on an after-tax and after insurance recovery basis, each Investor and its Affiliates and their respective directors, officers, employees and agents from and against any and all losses, claims, damages, liabilities and expenses (including without limitation reasonable attorney fees and disbursements and other expenses incurred in connection with investigating, preparing or defending any action, claim or proceeding, pending or threatened and the costs of enforcement hereof) (collectively, “Losses”) to which such Person may become subject as a result of any

-18-

breach of representation, warranty, covenant or agreement made by or to be performed on the part of the Company under the Transaction Documents, and will reimburse any such Person for all such amounts as they are incurred by such Person.

8.3 Conduct of Indemnification Proceedings. Promptly after receipt by any Person (the “Indemnified Person”) of notice of any demand, claim or circumstances which would or might give rise to a claim or the commencement of any action, proceeding or investigation in respect of which indemnity may be sought pursuant to Section 8.2, such Indemnified Person shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person, and shall assume the payment of all fees and expenses; provided, however, that the failure of any Indemnified Person so to notify the Company shall not relieve the Company of its obligations hereunder except to the extent that the Company is materially prejudiced by such failure to notify. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel (which counsel shall be reasonably satisfactory to the Company), but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless: (i) the Company and the Indemnified Person shall have mutually agreed to the retention of such counsel; or (ii) in the reasonable judgment of counsel to such Indemnified Person representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Company shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, but if settled with such consent, or if there be a final judgment for the plaintiff, the Company shall indemnify and hold harmless such Indemnified Person from and against any loss or liability (to the extent stated above) by reason of such settlement or judgment. Without the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld, the Company shall not effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Person from all liability arising out of such proceeding.
