Includes 2,000,000 additional shares of Common Stock, available for issuance under the 2021 Plan, as approved by the Registrant's Board of Directors on April 16, 2026 and the Registrant's stockholders on June 30, 2026. 

Estimated in accordance with Rule 457(c) and (h) of the Securities Act solely for the purpose of calculating the registration fee on the basis of $0.9521 per share, which is the average of the high and low prices of the Registrant's Common Stock as reported on the Nasdaq Capital Market on June 29, 2026.

The Registrant does not have any fee offsets.
