requests for registration) would materially adversely affect the marketability of the offering of the securities proposed to be registered by the Company, then such Holder shall be entitled to participate pro rata (based on the number of shares owned by the respective Holders) with the other Holders having similar piggyback registration rights with respect to such registration to the extent the managing underwriter determines that such securities may be included without such material adverse effect.

(c) Notwithstanding the provisions of this Section 7.2, the Company shall have the right at any time after it shall have given written notice pursuant to this Section 7.2 (irrespective of whether a written request for inclusion of any such securities shall have been made) to elect not to file any such proposed registration statement, or to withdraw the same after the filing but prior to the effective date thereof.

(h) If required by the underwriters in connection with an underwritten offering which includes Registrable Securities pursuant to this Section 7, the Company shall enter into an underwriting agreement with one or more underwriters selected for such underwriting. Such underwriting agreement shall be satisfactory in form and substance to the Company, the Underwriter and each other Holder of the Registrable Securities, and shall contain such representations, warranties and covenants by the Company and such other terms as are customarily contained in agreements of that type used by the underwriters. If required by the underwriters, the Underwriter and the other Holders of the Registrable Securities shall be parties to any underwriting agreement relating to an underwritten sale of their Registrable Securities and may, at their option, require that any or all the representations and warranties of the Company to or for the benefit of such underwriters shall, to the extent that they may be applicable, also be made to and for the benefit of the Underwriter and the other Holders of the Registrable Securities.

(j) The Company shall promptly notify the Underwriter and each Holder of the Registrable Securities covered by such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Act, upon the Company's discovery that, or upon the happening of any event as a result of which, the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made, and upon receipt of such notice the Underwriter and each Holder shall not effect any sale of securities and shall immediately cease utilizing or distributing such prospectus. At the request of the Underwriter or any such Holder, the Company shall promptly prepare and furnish to the Underwriter or such Holder and each underwriter, if any, a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such securities, such prospectus shall not include 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 not misleading in the light of the circumstances under which they were made.

8. Adjustments to Exercise Price and Number of Securities.

8.1 Adjustments to Underwriter's Warrants. The Exercise Price of the Underwriter's Warrants and number of securities issuable with respect to the Underwriter's Warrants shall be adjusted on the same terms and conditions, and at the same time, as any adjustments in the Exercise Price and number of shares issuable with respect to the Offered Warrants required by the terms of the Offered Warrants.

8.2 Adjustment to Number of Underwriter's Shares. The number of Underwriter's Shares to be received upon exercise of the Underwriter's Unit Warrants shall be subject to adjustment as follows:

(a) In the event that the number of outstanding Common Shares is increased by a stock dividend payable in Common Shares or by a subdivision of the outstanding Common Shares, then, from and after the effective time of such increase by reason of such dividend or subdivision, the

number of Common Shares issuable upon the exercise of each Underwriter's Unit Warrant shall be increased in proportion to such increase in outstanding shares. In the event that the number of Common Shares outstanding is decreased by a combination of the outstanding Common Shares, then, from and after the effective time of such decrease by reason of such combination, the number of Common Shares issuable upon the exercise of each Underwriter's Unit Warrant shall be decreased in proportion to such decrease in the outstanding Common Shares.

(b) In case of any reorganization or reclassification of the outstanding Common Shares (other than a change in par value, or from par value to no par value, or as a result of a subdivision or combination), or in case of any consolidation of the Company with, or merger of the Company into, another corporation (other than a consolidation or merger in which the Company is the continuing corporation and which does not result in any reclassification of the outstanding Common Shares), or in case of any sale or conveyance to another corporation of the property of the Company as an entirety or substantially as an entirety, the Holder of each Underwriter's Unit Warrant then outstanding shall thereafter have the right to purchase the kind and amount of Common Shares and other securities and property receivable upon such reorganization, reclassification, consolidation, merger, sale or conveyance by a holder of the number of Common Shares that the Holder of such Underwriter's Unit Warrant shall then be entitled to purchase; such adjustments shall apply with respect to all such changes occurring between the date of this Agreement and the date of exercise of such Underwriter's Unit Warrant.

(c) Subject to the provisions of this Section 8, in case the Company shall, at any time prior to the exercise of the Underwriter's Unit Warrants or Underwriter's Warrants, make any distribution of its assets to holders of its Common Shares as a liquidating or a partial liquidating dividend, then the Holders of Underwriter's Unit Warrants or Underwriter's Warrants who exercises its Underwriter's Unit Warrants or Underwriter's Warrants after the record date for the determination of those holders of Common Shares entitled to such distribution of assets as a liquidating or partial liquidating dividend shall be entitled to receive for the Unit Exercise Price per Underwriter's Unit or the Warrant Exercise Price per Underwriter's Warrant, in addition to each Common Share, the amount of such distribution or, at the option of the Company, a sum equal to the value of any such assets at the time of such distribution as determined by the Board of Directors of the Company in good faith, which would have been payable to such Holder had such Holder been the holder of record of the Common Shares receivable upon exercise of its Underwriter's Unit Warrant or Underwriter's Warrant on the record date for the determination of those entitled to such distribution.

(d) In case of the dissolution, liquidation or winding up of the Company, all rights under the Underwriter's Unit Warrants shall terminate on a date fixed by the Company, such date to be no earlier than ten (10) days prior to the effectiveness of such dissolution, liquidation or winding up and not later than five (5) days prior to such effectiveness. Notice of such termination of purchase rights shall be given to the last registered holder of the Underwriter's Unit Warrants, as the same shall appear on the books of the Company maintained by the Warrant Agent, by registered mail at least thirty (30) days prior to such termination date.

(e) In case the Company shall, at any time prior to the expiration of the Underwriter's Unit Warrants and prior to the exercise thereof, offer to the holders of its Common Shares any rights to subscribe for additional shares of any class of capital stock of the Company, then the Company shall give written notice thereof to the registered holders of the Underwriter's Unit Warrants not less than thirty (30) days prior to the date on which the books of the Company are closed or a record date is fixed for the determination of the stockholders entitled to such subscription rights. Such notice shall specify the date as to which the books shall be closed or the record date fixed with respect to such offer of subscription and the right of the holders of the Underwriter's Unit Warrants to participate in such offer of subscription shall terminate if the Underwriter's Unit

Warrant shall not be exercised on or before the date of such closing of the books or such record date.

(f) Any adjustment pursuant to the aforesaid provisions of this Section 8 shall be made on the basis of the number of Common Shares that the holder thereof would have been entitled to acquire upon the exercise of the Underwriter's Unit Warrant immediately prior to the event giving rise to such adjustment.

9. Exchange and Replacement of Underwriter's Unit Warrants. Each Underwriter's Unit Warrant is exchangeable without expense, upon the surrender thereof by the registered Holder at the principal executive office of the Company, for a new Underwriter's Unit Warrant of like tenor and date representing in the aggregate the right to purchase the same number of Underwriter's Shares and Underwriter's Warrants as provided in the original Underwriter's Unit Warrant in such denominations as shall be designated by the Holder thereof at the time of such surrender.

Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of any Underwriter's Unit Warrant, and, in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it, and reimbursement to the Company of all reasonable expenses incidental thereto, and upon surrender and cancellation of the Underwriter's Unit Warrant, if mutilated, the Company will make and deliver a new Underwriter's Unit Warrant of like tenor, in lieu thereof.

10. Elimination of Fractional Interests. The Company shall not be required to issue certificates representing fractions of Underwriter's Shares upon the exercise of the Underwriter's Unit Warrant. However, if a holder of an Underwriter's Unit Warrant exercises all warrants then owned of record by such holder and such exercise would result in the issuance of a fractional share, the Company will pay to such holder, in lieu of the issuance of any fractional share otherwise issuable, an amount of cash based on the market value of the Common Shares of the Company on the last trading day prior to the exercise date.

11. Reservation and Listing of Securities. The Company shall at all times reserve and keep available out of its authorized Common Shares, solely for the purpose of issuance upon the exercise of the Underwriter's Unit Warrant and Underwriter's Warrants, such number of Common Shares or other securities, properties or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of the Underwriter's Unit Warrant and/or the Underwriter's Warrants and payment of the Exercise Price therefor, all Underwriter's Shares and other securities issuable upon such exercise shall be duly and validly issued, fully paid, non-assessable and not subject to the preemptive rights of any stockholder. As long as the Underwriter's Unit Warrant and/or Underwriter's Warrants shall be outstanding, the Company shall use its best efforts to cause all Underwriter's Units, Underwriter's Shares, Underwriter's Warrants and all Common Shares issuable upon the exercise of the Underwriter's Warrants to be listed (subject to official notice of issuance) on all securities exchanges on which the Common Shares may then be listed and/or quoted on the American Stock Exchange (the "AMEX").

12. Notices to Underwriter's Unit Warrant Holders. Nothing contained in this Agreement shall be construed as conferring upon the Holders the right to vote or to consent or to receive notice as a stockholder in respect of any meetings of stockholders for the election of directors or any other matter, or any rights whatsoever as a stockholder of the Company. If, however, at any time prior to the expiration of the Underwriter's Unit Warrant or Underwriter's Warrants and their exercise, any of the following events shall occur:

(a) the Company shall take a record of the holders of its Common Shares for the purpose of entitling them to receive a dividend or distribution payable otherwise than in cash, or a cash

dividend or distribution payable otherwise than out of current or retained earnings, as indicated by the accounting treatment of such dividend or distribution on the books of the Company; or

(b) the Company shall offer to all the holders of its Common Shares any additional shares of capital stock of the Company or securities convertible into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to subscribe therefor; or

(c) a dissolution, liquidation or winding up of the Company (other than in connection with a consolidation or merger) or a sale of all or substantially all of its property, assets and business as an entirety shall be proposed; or

(d) a Change in Control of the Company occurs;

then, in any one or more of such events the Company shall give written notice of such event at least twenty (20) days prior to the date fixed as a record date or the date of closing the transfer books for the determination of the stockholders entitled to such dividend, distribution, convertible or exchangeable securities or subscription rights, or entitled to vote on such proposed dissolution, liquidation, winding up or sale. Such notice shall specify such record date or the date of closing the transfer books, as the case may be. Failure to give such notice or any defect therein shall not affect the validity of any action taken in connection with the declaration or payment of any such dividend, distribution or the issuance of any convertible or exchangeable securities, or subscription rights, options or warrants, or any proposed dissolution, liquidation, winding up or sale. A "Change of Control" occurs when (a) the Company merges or consolidates with another corporation or entity; (b) a person or group other than certain of the Company's existing stockholders becomes the beneficial owner of 25% or more of the aggregate voting power of the Company; or (c) during any period of two consecutive calendar years, certain changes in the composition of the Company's present Board of Directors occur, including any plans or proposals to change the number or term of Directors or to fill any existing vacancies on the Board, except for the possible addition by the Company of one or more independent directors to its Board of Directors.
