The rights, including the liquidation and dividend rights, of the holders of Class A, LT10 and LT50 common stock are identical, except with respect to voting, conversion and transfer rights. Each share of Class A common stock is entitled to one vote per share, each share of LT10 common stock is entitled to 10 votes per share and each share of LT50 common stock is entitled to 50 votes per share. Each share of LT10 and LT50 common stock is convertible into one share of Class A common stock voluntarily at the option of the holder after the satisfaction of certain requirements, which includes a ten months notice period for LT10 common stock and 48 months notice period for LT50 common stock to convert to Class A common stock, or automatically upon certain events. The Class A common stock has no conversion rights. As the liquidation and dividend rights are identical for Class A, LT10 and LT50 common stock, the undistributed earnings are allocated on a proportional basis based on the number of weighted-average shares within each class of common stock during the period and the resulting net loss per share attributable to common stockholders will be the same for the Class A, LT10, and LT50 common stock on an individual or combined basis.

The following potentially dilutive shares were not included in the calculation of diluted shares outstanding as the effect would have been anti-dilutive:
