(1) Estimated solely for the purpose of calculating the registration fee pursuant to Rule 457(o) under the Securities Act of 1933.

(2) No fee pursuant to Rule 457(g) of the Securities Act.

(3) The proposed maximum aggregate offering price of the 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 offered and sold in the offering, and as such the proposed maximum offering price of the common stock and pre-funded warrants (including the common stock issuable upon exercise of the pre-funded warrants) if any, is $15,000,000.

(4) The registrant may issue pre-funded warrants to purchase common shares in the offering. The purchase price of each pre-funded warrant will equal the price per share at which shares of common shares are being sold to the public in this offering, minus $0.01, which constitutes the pre-funded portion of the exercise price, and the remaining unpaid exercise price of the pre-funded warrant will equal $0.01 per share (subject to adjustment as provided for therein).

(5) In addition to the shares of Common Stock set forth in this table, pursuant to Rule 416 under the Securities Act of 1933, as amended, this registration statement also registers such indeterminate number of shares of Common Stock as may become issuable upon exercise of the pre-funded warrants and Class A Warrants as the same may be adjusted as a result of their anti-dilution provisions.
