Company may, in its sole discretion, deliver a Put Notice to the Investor which
states the dollar amount (designated in U.S. Dollars) (the "Put Amount"), which
the Company intends to sell to the Investor on a Closing Date (the "Put"). The
Put Notice shall be in the form attached hereto as Exhibit C and incorporated
herein by reference. The amount that the Company shall be entitled to Put to the
