Offering Note

1

Pursuant to Rule 416 under the Securities Act of 1933, as amended (the "Securities Act"), the shares of Common Stock being registered hereby include an indeterminate number of shares of Common Stock that may be issuable as a result of stock splits, stock dividends or similar transactions. Estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(o) under the Securities Act. The proposed maximum aggregate offering price of Common Stock proposed to be sold in the offering will be reduced on a dollar-for-dollar basis based on the offering price of any Pre-Funded Warrants issued in the offering, and the proposed maximum aggregate offering price of the Pre-Funded Warrants to be issued in the offering will be reduced on a dollar-for-dollar basis based on the offering price of any Common Stock issued in the offering. Accordingly, the proposed maximum aggregate offering price of the Common Stock and the Pre-Funded Warrants (including the Common Stock issuable upon exercise of the Pre-Funded Warrants), if any, is $10,000,000.

2

Estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(o) under the Securities Act. In accordance with Rule 457(g), because the shares of Common Stock underlying the Pre-Funded Warrants are registered hereby, no separate registration fee is payable with respect to the Pre-Funded Warrants or the Common Stock issuable upon exercise thereof.
