To the Board of Directors: OVERVIEW OF EXECUTIVE COMPENSATION The goal of the BioSource executive compensation program is to attract and retain talented biotechnology and life sciences industry executives that are necessary for the Company to maximize returns to stockholders. There are three elements to the BioSource executive compensation program designed to achieve those goals. . Base salary levels appropriate for the stage of development of BioSource. . Equity participation through the BioSource stock option program that will reward individuals when share prices increase. Individuals are given grants that reflect their relative impact on Company performance. . Incentive compensation that rewards individual performance when corporate goals are met. Total executive compensation from salary and incentives are within a competitive range for executives in the biotechnology and life sciences industries, when compared to companies of similar size and stage of development. Competitive compensation ranges are based on information derived at the beginning of 1996 from the RADFORD survey of compensation levels in this industry and additional companies chosen because of their comparable nature in the biotechnology field. An important element in the compensation package is stock options. The board supports the wide use of this incentive within BioSource. While widely used, the total number of options outstanding is not expected to result in undue dilution of stockholders' equity. The total amount of shares in the BioSource stock option pool is approximately 22% of total shares outstanding. This compares to the average of 17.5% of shares outstanding for biotechnology companies in the RADFORD survey with 100-300 employees. The Board has believed and continues to believe that a factor to be considered when comparing these compensation parameters is that the employees of BioSource believe in the long term growth of the Company. The management team believes that attainment of future growth is less speculative for BioSource than some of the peer group companies used in the compensation surveys. This will be reflected in the future value of stock options that will outweigh the relatively low compensation rankings attained by the management group in these surveys. DISCUSSION OF CHIEF EXECUTIVE OFFICER COMPENSATION In addition to the RADFORD survey, an additional comparison was performed in 1996 against 12 other small public biomedical companies. In the RADFORD survey, the base salary paid to the CEO was the lowest in a group of 83 reporting companies with 51-149 employees. The compensation of the CEO was also compared to a group of 12 other small public biomedical companies. In this group of 13, the CEO ranked 10th of the 13 companies, just above the bottom 25th percentile. The incentive cash compensation paid to the CEO was well below the average of 26% in the RADFORD survey, and total cash compensation remained in the bottom 10% of reporting companies. The Board had previously announced its policy of continuing to maintain executive salaries consistent with the revenue levels of the Company, profitability and a policy of overall cost control. It also indicated that it was not the intention of the Board to maintain indefinitely the executive compensation levels within BioSource at a low level compared to other companies in the biotechnology and life sciences fields, and that as the Company continues to progress, it was planned that salary and incentive compensation for the CEO will trend toward the middle of this group. For these reasons, in 1998, the CEO's annual compensation was increased to $250,000. DISCUSSION OF SENIOR EXECUTIVE COMPENSATION The average salary of the executives reporting to the CEO also ranks low among comparable companies. The Board believes this is reflective of both the early stage of the Company's development and the relative time in position for these executives as a group. Because of the relative pay, stock options have been used widely as a compensation tool within this group. As with the Chief Executive Officer, the 1998 compensation for certasin senior executives was increased as well. Each senior executive of the Company, including the CEO, has personal achievement goals to which incentive compensation is tied. To receive incentive compensation, corporate goals must also be attained. Compensation Committee of the Board of Directors: Leonard M. Hendrickson David J.
