This excerpt taken from the LOGI DEF 14A filed Jul 23, 2009.
Restricted Shares. Restricted share awards are awards of Logitech shares that vest in accordance with terms and conditions established by the administrator. The administrator may impose whatever conditions to vesting it determines to be appropriate. Each award of restricted shares is evidenced by an award agreement specifying the terms and conditions of the award. The administrator will determine the number of restricted shares granted to any employee. The administrator also determines the purchase price of any grants of restricted shares and, unless the administrator determines otherwise, shares that do not vest typically will be subject to forfeiture or to our right of repurchase, which we may exercise upon the voluntary or involuntary termination of the purchasers service with us for any reason including death or disability.
