Calculated under Section 6(b) of the Securities Act as $0.0001381 times the proposed maximum aggregate offering price.

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

As estimated solely for the purpose of calculating the registration fee pursuant to Rule 457(g) under the Securities Act, the proposed maximum aggregate offering price of the shares of Common Stock underlying the Underwriter Warrants is $6,875,000, which is equal to 110% of $6,250,000 (5.0% of the proposed maximum aggregate offering price of $125,000,000).</ffd:OfferingNote>
