Restrictions on Transfer. (a) This Warrant and any Warrant Shares may not be sold, transferred, pledged, hypothecated or otherwise disposed of except as follows: (i) to a person who, in the opinion of counsel to the Company, is a person to whom this Warrant or the Warrant Shares may legally be transferred without registration and without the delivery of a current prospectus under the Act with respect thereto, and then only against receipt of an agreement of such person to comply with the provisions of this Section 6(a) with respect to any resale or other disposition of such securities; or (ii) to any person upon delivery of a prospectus then meeting the requirements of the Act relating to such securities and the offering thereof for such sale or disposition, and thereafter to all successive assignees. (b) Unless the Warrant Shares have been registered under the Act, upon exercise of any of the Warrant and the issuance of any of the Warrant Shares, all certificates representing Warrant Shares shall bear on the face thereof substantially the following legend: "THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). SUCH SECURITIES MAY NOT BE OFFERED OR SOLD OR TRANSFERRED IN THE UNITED STATES OR TO U.S. PERSONS IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT WHICH, EXCEPT IN THE CASE OF AN EXEMPTION PURSUANT TO RULE 144 UNDER SAID ACT, IS CONFIRMED IN A LEGAL OPINION SATISFACTORY TO THE COMPANY." The holder of the Warrant agrees and acknowledges that the Warrant is being purchased for the holder's own account, for investment purposes only, and not for the account of any other person, and not with a view to distribution, assignment, pledge or resale to others or to fractionalization in whole or in part. The holder further represents, warrants and agrees as follows: no other person has or will have a direct or indirect beneficial interest in this Warrant and the holder will not sell, hypothecate or otherwise transfer the Warrant except in accordance with the Act thereunder and applicable state securities laws or unless, in the opinion of counsel for the holder acceptable to the Company, an exemption from the registration requirements of the Act and such laws is available. 7. Closing of Books. The Company will at no time close its shareholder books or records in any manner which interferes with the timely exercise of this Warrant. 8. No Rights as Shareholder until Exercise. This Warrant does not entitle the holder hereof to any voting rights or other rights as a shareholder of the Company prior to the exercise thereof. If, however, at the time of the surrender of this Warrant and purchase the holder hereof shall be entitled to exercise this Warrant, the 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 date on which this Warrant shall have been exercised. 9. Assignment and Transfer of Warrant. This Warrant may be assigned by the surrender of this Warrant and the Assignment Form annexed hereto duly executed at the office of the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered holder hereof at the address of such holder appearing on the books of the Company); provided, however, that this Warrant may not be resold or otherwise transferred except (i) in a transaction registered under the Act, or (ii) in a transaction pursuant to an exemption, if available, from such registration and whereby, if requested by the Company, an opinion of counsel reasonably satisfactory to the Company is obtained by the holder of this Warrant to the effect that the transaction is so exempt. 10. Loss, Theft, Destruction or Mutilation of Warrant. The Company represents and warrants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of any Warrant or stock certificate, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it, and upon reimbursement to the Company of all reasonable expenses incidental thereto, 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 this Warrant or stock certificate. 11. 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 legal holiday. 12. Effect of Certain Events. (a) If at any time the Company proposes (i) to sell or otherwise convey all or substantially all of its assets or (ii) to effect a transaction (by merger or otherwise) in which more than 50% of the voting power of the Company is disposed of (collectively, a "Sale or Merger Transaction"), in which the consideration to be received by the Company or its shareholders consists solely of cash, the Company shall give the holder of this Warrant thirty (30) days' notice of the proposed effective date of the transaction specifying that the Warrant shall terminate if the Warrant has not been exercised by the effective date of the transaction. (b) In case the Company shall at any time effect a Sale or Merger Transaction in which the consideration to be received by the Company or its shareholders consists in part of consideration other than cash, the holder of this Warrant shall have the right thereafter to purchase, by exercise of this Warrant and payment of the aggregate Exercise Price in effect immediately prior to such action, the kind and amount of shares and other securities and property which it would have owned or have been entitled to receive after the happening of such transaction had this Warrant been exercised immediately prior thereto. (c) "Piggy-Back" Registration. The Holder of this Warrant shall have the right to include all of the shares of Common Stock underlying this Warrant (the "Registrable Securities") as part of any registration of securities filed by the Company (other than in connection with a transaction contemplated by Rule 145(a) promulgated under the Act or pursuant to Form S-8) and must be notified in writing of such filing; provided, however, that the holder of this Warrant agrees it shall not have any piggy-back registration rights pursuant to this Section 12(c) if the shares of Common Stock underlying this Warrant are freely tradable in the United States pursuant to the provisions of Regulation D. Holder shall have five (5) business days to notify the Company in writing as to whether the Company is to include Holder or not include Holder as part of the registration; provided, however, that if any registration pursuant to this Section shall be underwritten, in whole or in part, the Company may require that the Registrable Securities requested for inclusion pursuant to this Section be included in the underwriting on the same terms and conditions as the securities otherwise being sold through the underwriters. If in the good faith judgment of the underwriter evidenced in writing of such offering only a limited number of Registrable Securities should be included in such offering, or no such shares should be included, the Holder, and all other selling stockholders, shall be limited to registering such proportion of their respective shares as shall equal the proportion that the number of shares of selling stockholders permitted to be registered by the underwriter in such offering bears to the total number of all shares then held by all selling stockholders desiring to participate in such offering. Those Registrable Securities which are excluded from an underwritten offering pursuant to the foregoing provisions of this Section (and all other Registrable Securities held by the selling stockholders) shall be withheld from the market by the Holders thereof for a period, not to exceed one hundred eighty (180) days, which the underwriter may reasonably determine is necessary in order to effect such underwritten offering. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 12(c) prior to the effectiveness of such registration whether or not any Warrant holder elected to include securities in such registration. All registration expenses incurred by the Company in complying with this Section 12(c) shall be paid by the Company, exclusive of underwriting discounts, commissions and legal fees and expenses for counsel to the holders of the Warrants. 13. Adjustments of Exercise Price and Number of Warrant Shares. 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) declare or 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, (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, the number of Warrant Shares purchasable upon exercise of this Warrant immediately prior thereto shall be adjusted so that the holder of this Warrant shall be entitled to receive the kind and number of Warrant Shares or other securities of the Company which he would have owned or have been entitled to receive had such Warrant been exercised in advance thereof. 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. 14. Voluntary Adjustment by the Company. The Company may at its discretion, 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. 15. 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 promptly mail by registered or certified mail, return receipt requested, to the holder of this Warrant notice of such adjustment or adjustments setting forth 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 after such adjustment, setting forth a brief statement of the facts requiring such adjustment and setting forth computation by which such adjustment was made. Such notice, in absence of manifest error, shall be conclusive evidence of the correctness of such adjustment. 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 Common Stock 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 shares of the Company's Common Stock 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 shares of Common Stock may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the NASDAQ National Market System or any domestic securities exchange upon which the Common Stock may be listed. 17. Miscellaneous. (a) Issue Date; Jurisdiction. The provisions of this Warrant shall be construed and shall be given effect in all respects as if it had been issued and delivered by the Company on the date hereof. This Warrant shall be binding upon any successors or assigns of the Company. This Warrant shall constitute a contract under the laws and jurisdictions of New York and for all purposes shall be construed in accordance with and governed by the laws of said state without regard to its conflict of law, principles or rules. (b) Restrictions. The holder hereof acknowledges that the Common Stock acquired upon the exercise of this Warrant, if not registered, may have restrictions upon its resale imposed by state and federal securities laws. (c) Modification and Waiver. This Warrant and any provisions hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the party against which enforcement of the same is sought. (d) Notices. Any notice, request or other document required or permitted to be given or delivered to the holders hereof of the Company shall be delivered or shall be sent by certified or registered mail, postage prepaid, to each such holder at its address as shown on the books of the Company or to the Company at the address set forth in the Agreement.
