Sales of the ATM Shares, if any, under the Agreement may be made in transactions that are deemed to be “at the market offerings” as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended. The Company has no obligation to sell any of the ATM Shares and may at any time suspend offers under the Agreement or terminate the Agreement.
