On March 30, 2007, the Board of Directors of EnerSys approved the EnerSys Management Incentive Plan for Fiscal Year 2008 (the "2008 MIP"). The 2008 MIP generally provides for annual cash bonus awards to our executive officers and other eligible employees upon the achievement of certain corporate objectives. There are two corporate performance measures in the 2008 MIP, one based on corporate profitability, and one based on level of indebtedness. The bonus payout ranges from 15% to 100% of base salary for our Chief Executive Officer, and from 9% to 60% of base salary for our other executive officers. Our CEO and other executive officers of the Company can earn an additional 70% and 42%, respectively, of their base salaries if our corporate profitability exceeds the base target and meets "stretch" targets set by our Compensation Committee. The foregoing description does not constitute a complete summary of the 2008 MIP. Refer to the 2008 MIP, which is attached hereto as Exhibit 10.1 and incorporated by reference, for a complete description.</font>
