6. Net Loss per Common Share

The following potentially dilutive options to purchase shares of common stock and unvested restricted common stock at December 31 were excluded from diluted net loss per common share because of their anti-dilutive effect, and therefore, basic net loss per common share equals dilutive net loss per common share for all periods presented in our Consolidated Statements of Operations:

	Number of options and unvested restricted stock	Range of stock option exercise prices
