 definition
of Fundamental Transactions includes, but is not limited to, mergers, a sale of all or substantially all of the Company’s assets,
certain tender offers and other transactions that result in a change of control. Further, in connection with a Change of Control (as defined
in the Warrants), upon request of a holder of a Selling Shareholder Warrant, the Company or the Successor Entity (as defined in the Warrants),
as the case may be, shall exchange a Selling Shareholder Warrant for consideration equal to the Black Scholes Value (as defined in the
Selling Shareholder Warrants) of such portion of such Selling Shareholder Warrant subject to exchange in cash. The definition of Change
of Control is generally the same as the definition of Fundamental Transaction but excludes certain types of Fundamental Transactions.
