Report of the Compensation Committee Regarding Executive Compensation*

The Compensation Committee, composed of directors Daniels, Streetman, AshbyRoesslein and Roesslein,Le, is responsible for determining the compensation programs and levels of pay for the Company'sCompany’s executive officers. The Compensation Committee also advises management on pay programs and levels for other employees. The Compensation Committee utilizes independent survey data for analyses of competitive industry pay levels and practices, and to guide the Compensation Committee on appropriate pay levels for the Company.

Compensation Philosophy and Objectives.    The Company'sCompany’s basic philosophy is to align executive compensation with increases in stockholder value through growth in sales and operating profits. Primarily, this is accomplished through the use of stock options, which provide long-term compensation in direct proportion to increases in stockholder value, and profit sharing. In addition, the Company believes it is important to emphasize teamwork, entrepreneurship and active participation by all employees. This is accomplished through providing options to a majority ofsubstantially all full-time, exempt domestic employees and similarly situated international employees, and through cash incentives, through which both executive and other employees receive cash bonuses based on company-wide financial goals. Finally, it is the Company'sCompany’s philosophy that no special perquisites should be provided to senior executives.

Executive Compensation Programs.    The Company'sCompany’s executive compensation programs consist of three principal elements: base salary, cash bonus and stock options. The Company emphasizes incentive compensation in the form of stock options and bonuses, rather than base salary. The Compensation Committee has adopted a guideline that executives should be paid competitive base salaries. The Committee sets the annual base salary for executives. Prior to making its determination, the Compensation Committee reviews historical compensation levels of the executives, evaluations of past performance, assessments of expected future contributions of the executives, competitive pay levels and programs provided by other comparable companies, and general industry pay practices. In making its determinations, the Committee does not utilize any particular indices or formulae to arrive at each executive'sexecutive’s recommended pay level. In a demonstration of leadership during the economically challenging times, of 2001, the executive officers proposed that the Company temporarily reduce their base salaries. In response, the base salary of each executive officer, except the Vice President of Sales, was adjusted to reflect a 5% reduction effective October 1, 2001. In 2002, the Committee granted Dr. Truchard discretion to reinstate the September 30, 2001 salaries of executives when he deemed appropriate. Under this discretion, the executives’ salaries were reinstated to their September 30, 2001 level effective July 1, 2002.

For many years, the Company has maintained a cash bonus plan under which executive officers participate. In recent years, this plan provided for a target incentive to be paid based on achieving pre-determined levels of revenue growth and profitability. For fiscal 2002, 2001 2000 and 19992000 these goals were 40% revenue growth and 18% operating profit as a percent of revenue, the same goals as for all other employees. At the end of each year, actual results for the Company are compared to these targets and executive bonuses are based on actual Company performance in relation to these factors. If there is no growth or no profitability, no cash bonuses are payable to executive officers. Individual performance is not considered in determining the bonus of individual officers for the cash bonus program.

In 1999, the Company added a discretionary cash bonus program for executive officersexecutives and other employees which is funded based upon the achievement of the Company'sCompany’s minimum quarterly growth goal and with payments based upon individual performance. The program was adjusted as of the second quarter of 2000 to provide that if the Company meets its minimum quarterly revenue growth goal, a percentage of payroll will be available as a discretionary cash bonus pool for distribution to executive and other employees. For fiscal year 2001,2002, the minimum quarterly growth goal was 20% revenue growth over the same period in the prior year. As a result of the program, executives and other employees are eligible to receive the discretionary cash bonus on a quarterly basis. Separate from the discretionary cash bonus program, in December 2001, the Company paid each executive officer, except Dr. Truchard, a bonus award of approximately $1,400 in appreciation of their management efforts throughout fiscal year 2001. In addition, the Vice President, Sales is eligible for a separate company sales commission program based upon growth and profitability performance measures approved by the Board of Directors. Compensation Committee.

14


Total compensation for executive officers also includes long-term incentives in the form of stock options, which are generally provided through initial stock option grants at the date of hire and periodic additional stock option grants. Stock options are instrumental in promoting the alignment of long-term interests between the Company'sCompany’s executive officers and stockholders due to the fact that executives realize gains only if the stock price increases over the fair market value at the date of grant and the executives exercise their options. In determining the amount of such grants, the Committee evaluates 12 the job level of the executive, responsibilities of the executive, and competitive practices in the industry. All options are granted at 100% of fair market value at the date of grant. Options to executive officers and other employees vest over a period of five years or ten years, subject to acceleration based on Company performance (in case of special option grants to executives); however,. Mr. Ravel also has the right to a maximum of twelve months of accelerated vesting of his stock holdingsoptions if his employment is constructively terminated or terminated without cause within three years of his hire date. The long-term value realized by executives through option exercises can be directly linked to the enhancement of stockholder value.

Chief Executive Officer Compensation.    While the Board was highly pleased with Dr. Truchard'sTruchard’s performance in 2001,2002, at his request, the Chief Executive Officer'sOfficer’s base salary (which had been reduced in October 2001) was reducedreinstated July 1, 2002 along with the other executive officers (as discussed above),but was not otherwise increased, and he received no stock options. Based on the same formula applied to other executive officers, Dr. Truchard did not receivereceived a bonus for 2001 and declined to receive the $1,400 bonus awarded to the other executive officers.2002. Dr. Truchard is the Company'sCompany’s largest stockholder with an ownership of approximately 25% of the Company'sCompany’s stock.

Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"“Code”), imposes a limit on tax deductions for annual compensation in excess of one million dollars paid by a corporation to its chief executive officer and the other four most highly compensated executive officers of a corporation. Deductions are, however, permitted if certain conditions are met, including a requirement that the plan under which such compensation is paid be reapproved by stockholders every five years. None of the compensation paid by the Company in fiscal 20012002 was subject to the limitation on deductibility. The Compensation Committee will continue to assess the impact of Section 162(m) of the Code on its compensation practices and determine what further action, if any, is appropriate.
