SAFETY-KLEEN CORP. 1997 MANAGEMENT INCENTIVE PLAN The Directors of Safety-Kleen Corp. have heretofore decided to compensate their officers and key management personnel under a compensation plan that will include base salary plus incentive bonus. The purpose of the incentive plan is to supplement by incentive bonuses the remuneration for officers and key management personnel which is competitive externally, equitable internally, and properly rewarding for performance in the responsibility assigned. On the recommendation of the Compensation Committee, the following Management Incentive Plan is hereby established for officers and key management personnel of the Company. I. CALCULATION OF MANAGEMENT INCENTIVE FUND Each year the Board of Directors will establish an EVA Target for the year and create an incentive fund, consisting of both a formula and discretionary fund, based on the improvement in EVA relative to the target as Follows: A. Expected EVA improvement is the dollar amount by which EVA must increase in any plan year relative to the actual EVA achieved in the prior plan year, in order for target bonuses to be funded Expected EVA improvement is an estimate of investor's expectations for Safety-Kleen operating performance. This estimate is derived based on the relationship between Safety-Kleen's market capitalization, its Capital, and its current EVA as of a certain date. B. EVA INTERVAL The EVA Interval represents the amount of deviation from Expected EVA Improvement that doubles (positive deviation) or eliminates (negative deviation) target bonuses. The EVA Interval reflects the inherent volatility of a business to ensure that short-term cyclical business changes do not result in extreme positive or negative bonus declarations. The effect of a volatility based interval is that: (1) zero bonuses are declared for performance at about the 15th percentile of potential outcomes; and (2) Two times target bonuses are declared for performance at about the 85th percentile of potential outcomes. The EVA Interval for Safety-Kleen is initially based on the volatility of Safety-Kleen stock and the relationship of stock price to EVA improvement. The EVA Interval in future plan years will change in proportion to the aggregate target bonus pool. This maintains a consistent share of incremental EVA improvement between management and the shareholders. C. CALCULATION OF THE DISCRETIONARY ELEMENT OF THE PLAN In addition to the fund created by the above calculations, an additional fund consisting of an amount not exceeding 50% of the formula amount will be available for discretionary incentive allocations. II. ALLOCATION OF FUNDS A. DETERMINATION OF PLAN PARTICIPANTS Determination of who will participate in the Plan will be determined by the Compensation Committee (Committee). The Chief Executive Officer/Chairman of the Board (Chairman) and the President/COO (President) in consultation with other corporate officers, will make recommendations to the Committee. Eligibility will be in accordance with job responsibility and salary grade. The list of job classifications to be included in the Plan will be submitted at the beginning of each calendar year for the approval of the Committee. B. DETERMINATION OF INDIVIDUAL FUND SHARES The percentage share formula incentive fund for each officer participant will be recommended by the President and the Chairman and submitted to the Compensation Committee for its approval at the beginning of each calendar year. Non-officer participant percent shares will be developed by the President and the Chairman in consultation with other officers. C. PAYMENT OF ANNUAL INCENTIVE The individual share calculations for the formula incentive resulting from the above calculation, together with the recommended discretionary share, which can range from 0% to 50% of the formula amount, shall be submitted to the Compensation Committee for its final approval during the first quarter of the year following the fiscal year involved. The President and the Chairman will recommend the discretionary amount for each officer based on his analysis of each individual's performance during the year. A non-officer participant's discretionary share will be recommended by the participant's immediate supervisor for approval by the President and the Chairman. D. BONUS BANK Declared bonuses for participants will be paid from a Bonus Bank. A participant's declared bonus in a given year will be deposited into the Bonus Bank (and thereby added to any existing Bonus Bank balance). (Exhibit 1) Bonuses will be paid from the Bonus Bank as follows: 1. 100% of available Bonus Bank balance will be paid up to the participant's target award; 2. an additional 1/3 of any excess positive Bonus Bank balance will also be paid in the given year; 3. the remaining 2/3 of any excess positive Bonus Bank balance will remain in the Bonus Bank, to be paid out in future years based on future EVA performance of the participant's EVA business unit. III. INCENTIVE PLAN PARTICIPATION AND COMMUNICATIONS The President and the Chairman shall notify the Compensation Committee of the Board regarding officers and the key management position that will be included in the Plan for the current year. Such a list should be determined as early as possible in any fiscal year and no later than the end of the first quarter of each fiscal year. Early identification of participants is desirable to provide maximum opportunity for communicating throughout the year regarding company performance and each individual participant's related bonus opportunity, thereby maximizing the effectiveness of the Incentive Plan. IV. GENERAL PROVISIONS A. PLAN ELIGIBILITY To be eligible to participate under the plan, an officer or employee must be actively employed with the company on the last working day of the year for which the year's compensation is payable; provided, that in the event a participant's employment is terminated prior to year-end by reason of death occurring after June 1, his share of the formula incentive fund will be adjusted on the basis of his full-year share, prorated for the period of his actual employment. B. LESS THAN FULL-YEAR'S EMPLOYMENT In the event a participant's employment commences after January 1st and before October 1st, adjustment of his share of the formula incentive fund will be on the basis of his full share, prorated for the period of the participant's actual employment. Participants hired after October 1st will not receive an award for the current year. C. TRANSFERS A plan participant who is transferred from one EVA business unit to another EVA business unit during a plan year will receive bonus declarations and payments according to the following rules: 1. The award declared for the year of the transfer will be determined according to the full year EVA results of both EVA business units in which the participant worked during the plan year, and pro rated based on the number of months of service in each EVA business unit. 2. Any positive or negative bonus bank balance will be carried over. D. BONUS BANK BALANCES UPON TERMINATION In cases of termination's due to retirement at or after attainment of age 55, death, disability, reduction in force, or the sale or closing of a plant or EVA business unit, all positive Bonus Bank balances attributable to a terminating participant will be paid in full at the end of the plan year of termination. Bonus Bank balances are forfeitable upon termination for any reason not delineated above. V. CHANGE OF CONTROL A.
