The following potentially dilutive securities have been excluded from the computation of diluted weighted average shares outstanding as their effect would be anti-dilutive:

Options to purchase common stock		1,048,407		27,038
Restricted stock units, unvested portion		2,067		7,020

Common warrants		50,402		50,402

Total potential common stock equivalents		1,113,943		105,366

The outstanding pre-funded warrants are exercisable for only a de minimis cash consideration with no substantive exercise contingencies, accordingly, the Company included pre-funded warrants in the weighted average shares outstanding for both basic and diluted earnings per share calculations.
