[1] (1) Because the Company had a net loss during the six months ended June 30, 2023 and 2022, the Company's potentially dilutive securities, which include stock options, restricted stock, preferred stock, and warrants to purchase shares of common stock and preferred stock, have been excluded from the computation of diluted net loss per share, as the effect would be anti-dilutive.
