This excerpt taken from the LOOP DEF 14A filed Apr 18, 2007.
Restricted stock grants are awards of a specific number of shares of our common stock. Unless the administrator determines otherwise, the restricted stock agreement will grant LoopNet a repurchase option exercisable, or a forfeiture condition triggered, upon the voluntary or involuntary termination of the participants employment with LoopNet for any reason, including death or disability. The purchase price for shares repurchased pursuant to the restricted stock purchase agreement will be determined by the administrator. The repurchase option or forfeiture condition may lapse at a rate determined by the administrator. The grant, issuance and/or vesting of restricted stock may be subject to performance criteria, including qualifying performance criteria.
