EXHIBIT 10.9 - -------------------------------------------------------------------------------- WESTLAKE GROUP EVA Incentive Plan PARTICIPANT'S GUIDE AND PLAN SUMMARY ORIGINAL EFFECTIVE DATE: JANUARY 1, 2000 AMENDED: JANUARY 1, 2002 - -------------------------------------------------------------------------------- PLAN SUMMARY - -------------------------------------------------------------------------------- Westlake Group - EVA Incentive Plan - Summary PURPOSE & OBJECTIVE The objective of the Westlake Group Management Incentive Plan (MIP) is to reward executives, managers and selected key employees for their contributions toward building the growth and adding to the value of the company on behalf of the shareholders and investors. The plan is designed to provide these employees with a sense of ownership and opportunity to personally benefit from the increase in value of the company, thus, aiding in attracting and retaining key employees. HOW BONUSES ARE CALCULATED TARGET BONUS PERCENTAGE: A bonus target expressed as a percentage of base pay. This is the (X) factor applied to the Bonus Multiple earned to determine the final payment. Participants will be advised of their Target Bonus Percentage by their respective Vice President/Department Head. EVA TARGET OR EXPECTED IMPROVEMENT (EI): An EVA target will be established for each EVA Center at the start of each year. The EVA target is equal to the Expected Improvement (EI) in EVA relative to the previous year's EVA that is required to achieve a bonus payout equal to a multiple of 1X. The formula for Expected Improvement (EI) is: Olefins, Vinyls & Corporate: EI = BEGINNING CAPITAL * 0.6% - LAST YEAR EVA * 14.7% Fabricated Products: EI = - LAST YEAR EVA *10.8% The EVA Target for each successive period is calculated using the following formula: EVA TARGET = EI + LAST YEAR EVA 2 - -------------------------------------------------------------------------------- Westlake Group - EVA Incentive Plan - Summary BONUS MULTIPLE: Bonus Multiple is the factor applied to the Target Bonus % to determine the Declared Bonus for the period. This is calculated by dividing the "Excess Improvement" (Actual EVA Improvement - Target EVA Improvement) by the plan Interval and adding one (one is the target or "1X" performance). INTERVAL: The interval is the amount of EVA improvement over the target needed in order to increase the multiple to 2X, or the amount of EVA decline below the target that produces a 0X. The intervals for the various EVA Centers is summarized below: Note: The interval for WCC for the 2001 Plan Year only was amended to $40mm. o WCC (Consolidated): $35mm o Olefins: $30mm o Vinyls & Fab $20mm Thus, the formula to determine the Bonus Multiple is: (ACTUAL EVA IMPROVEMENT - TARGET EVA IMPROVEMENT) BONUS MULTIPLE = ------------------------------------------------- + 1 INTERVAL FIGURE 2 BELOW ILLUSTRATES THE IMPROVEMENT INTERVAL CONCEPT: [GRAPH] Other Factors: 3 - -------------------------------------------------------------------------------- Westlake Group - EVA Incentive Plan - Summary Meeting or Exceeding Expected Improvement in EVA is the principal element of this Plan; however, the success of the company is also based upon certain Non-Financial Factors and Individual Performance Factors. These factors will be evaluated and given a weight in determining the final Declared Bonus to be granted. NON-FINANCIAL FACTORS (NFF'S): These are Measurable factors that help drive the productivity and profitability of an EVA center and assist in building EVA. For example, safety, environmental compliance, product quality. Specific measures are determined for each factor and a method of combining these results with EVA results is developed to determine incentive compensation payments. These NFF's will be weighted up to 20% depending on the EVA Center. INDIVIDUAL PERFORMANCE FACTORS (IPF'S): Factors that are specific to the performance and contribution of an individual which are used to modify the gross declared bonus payment to be made. This factor ranges from .80 to 1.20. For example: 20% (Gross Declared Bonus) x .90 (IPF) = 18% (Actual Declared Bonus). IPF measures include the following major criteria. o Goal Attainment o Personal Contribution & Effort o Criticality o Managerial Success Factors, including: Value & Ethics Communications Skills Problem Solving Leadership & Vision People Management HSE Commitment EVA CENTERS: An EVA center is a business unit or function for which a specific EVA target has been established and for which NFF's have been set.
