share of common stock, no par value (“Common Stock”), and one warrant representing the right to purchase one

other holders of Rights pursuant to the exercise of their Basic Subscription Right (the “Over-Subscription Units”),
any Rights holder that exercises its Basic Subscription Right in full may purchase a number of Excess Units pursuant to the terms
and conditions of the Rights Offering (the “Over-Subscription Privilege”). The Rights represented by this Subscription

The undersigned acknowledges that the number
of Units that the undersigned may obtain by subscribing for units in this offering cannot be determined on the date subscription
of rights are exercised hereby, but that the undersigned will obtain the number of units equal to the result of dividing the accepted
dollar amount of investment by the Subscription Price on the Expiration Date.
