Restricted Stock Units

Restricted stock units are awards that give the holder the right to receive one share of common stock for each restricted stock unit upon meeting service-based vesting conditions (typically annual vesting in three equal annual installments, with a requirement that the holder remains in the continuous employment of the Company). The holders of unvested units do not have the same rights as stockholders including but not limited to any dividends which may be declared by the Company, and do not have the right to vote. The value of restricted stock units that vest over time is established by the market price on the date of its grant.
