Such shares shall be restricted so that no share may be transferred or alienated in any way (except through passage under will or by the laws of descent and distribution upon the Executive's death) until the shares are vested, at which time the restriction will lapse with respect to the vested shares. Such awards shall be granted pursuant to, and conditioned upon, execution by the Executive of restricted stock agreements with terms and conditions consistent with those of other senior executives of the Company. No Restricted Stock Bonuses shall be granted subsequent to termination of employment. The Company shall use its best efforts to cause a registration statement on form S-8 (or comparable successor form) covering all shares of restricted stock granted to the Executive as Restricted Stock Bonuses to remain effective until sixty (60) days after the lapse of all restrictions on the shares of restricted stock granted to the Executive as Restricted Stock Bonuses. 3.
