McDonald, Chief Executive Officer (400,000 shares), Mark D. Pierce, President (200,000 shares) and Kevin D. Struzeski, Chief Financial Officer (200,000 shares).  Under the terms of the restricted stock agreements, the forfeiture restrictions on one-third of the aggregate number of restricted shares awarded to each officer will lapse on each of the first three anniversaries of the date of the restricted stock agreement so long as such officer has been continuously employed by Carbon or one of its subsidiaries from the date of the restricted stock agreement through such applicable anniversary.  Pursuant to the restricted stock agreements, in the event of certain triggering events, such as a change in control of Carbon or an involuntary termination, death or disability of such officer (in each case as defined in the form of restricted stock agreement), the forfeiture restrictions shall lapse as to all remaining shares of restricted stock.  The foregoing is not a complete description of all the terms and conditions of the restricted stock agreements and is qualified in its entirety by the full text of the restricted stock agreement, a form of which is incorporated as Exhibit 10.1 to this Current Report on Form 8-K.
