Stock-Based Compensation |

|
We issue stock-based incentive awards to our eligible employees and Directors under two employee
stock ownership plans (the 1993 and 2002 Employee Stock Incentive Plans) and a Director Deferred
Stock Ownership Plan. No further awards may be granted under the 1993 Employees Stock Incentive
Plan, although awards granted under this plan remain outstanding in accordance with their terms.
The 2002 Employee Stock Incentive Plan permits the granting of nonqualified stock options, stock
appreciation rights, performance stock, restricted stock and other stock-based awards. |
