3. Potentially Dilutive Securities

The Company’s potentially dilutive securities, which include stock options and warrants and shares of common stock issuable upon conversion of convertible debt, have been excluded from the computation of diluted net loss per common share as the effect of including those securities would be to reduce the net loss per common share and be antidilutive. Therefore, the denominator used to calculate both basic and diluted net loss per common share is the same in each period presented. 

The following outstanding potentially dilutive securities have been excluded from the computations of diluted net loss per common share:

	2021		2020
Options to purchase common stock		4,224,111		3,420,930
