transaction, the holder of this Warrant shall have the right to purchase and
receive upon the basis and terms and conditions specified in this Warrant, and

the holders of a majority of the outstanding shares of the Company's Common
Stock, the Company shall not effect any consolidation, merger or sale with the
individual or entity having made such offer or with any Affiliate of such

opportunity to elect to receive upon the exercise of this Warrant either the
Shares then issuable with respect to the Shares of Common Stock or the stock,

designate in accordance with SECTION 11(c) hereof. This Warrant and the Shares
issued upon exercise hereof may not be offered, sold, or transferred except in

required from any purchaser of this Warrant or any underlying security pursuant

Holder's intention as to such disposition. Promptly upon receiving such notice,
the Company shall present a copy thereof to its securities counsel. If, in the
opinion of such counsel (or of other securities counsel reasonably acceptable to

security under the Act, or any similar statute then in effect, the Company
shall, as promptly as practicable, notify the Registered Holder of such opinion,
whereupon the Registered Holder shall be entitled to dispose of such security in
accordance with the terms of the notice delivered by the Registered Holder to
the Company.
