Persons Who May Participate in the 2006 Long-Term Incentive Plan
Any individual who provides services to the Company or its subsidiaries, including non-employee directors of and consultants for the Company (an “Eligible Person”), and who is designated by the Compensation Committee to receive an Award under the 2006 Plan will be a “Participant.” An employee on leave of absence may be considered still employed by the Company or a subsidiary for purposes of determining eligibility for participation under the 2006 Plan. Any individual granted an Award which remains outstanding under the 2006 Plan, including an individual who is no longer an Eligible Person, will continue to be a Participant for purposes of the 2006 Plan. The Company currently has ten non-employee directors, 18 officers and approximately 1,830 other employees who are eligible to participate in the 2006 Plan.
