Performance Unit Awards
This year we made multi-year performance unit awards to certain vice presidents and mid-level employees. Each award is made in accordance with the terms of the 2008 Omnibus Incentive Plan, but the terms of each award are specific to each employee. Mr. Bender received a performance unit award that is based on certain performance targets from June 2008 through December 2011. The performance unit awards vest in the fourth and fifth year after grant, assuming performance metrics are achieved and that Mr. Bender has remained in our employ. If all performance metrics are met over the performance period, Mr. Bender will receive a value equal to 5,654 units, payable in a cash equivalent at the time of payment or units, or a combination of both, as determined by the Compensation Committee.
