The Incentive Plan is authorized to issue up to 136.5 million shares of common stock. The Incentive Plan permits the granting of stock-based awards in the form of stock grants, restricted shares, restricted stock units, stock options or stock appreciation rights to eligible employees and non-employee directors. A restricted stock unit is the right to receive shares. The exercise price for stock options granted under this plan must be equal to or greater than the fair market value on the date of the grant.
