(1)
The Company's 1987 Stock Option Plan and 1995 Stock Plan (collectively the "Option Plans") provide for the grant of options and stock purchase rights to officers, employees and consultants of the Company. Options granted under the Option Plans may be either "nonstatutory options" or "incentive stock options." The exercise price is determined by the Board of Directors or its Compensation Committee and, in the case of incentive stock options, may not be less than 100% of the fair market value of the Common Stock on the date of grant (110% in the case of grants to 10% shareholders). The options expire not more than six years from the date of grant and may be exercised only while the optionee is employed by the Company or within such period of time after termination of employment as is determined by the Board or its Committee at the time of grant. The Board of Directors may determine when options granted may be exercisable.

(2)
The Company granted options to purchase an aggregate of 984,125 to all employees other than executive officers and granted options to purchase an aggregate of 545,000 shares to all executive officers as a group (7 persons), during fiscal 2001.

(3)
This column sets forth hypothetical gains or "option spreads" for the options at the end of their respective ten-year terms, as calculated in accordance with the rules of the Securities and Exchange Commission. Each gain is based on an arbitrarily assumed annualized rate of compound appreciation of the market price at the date of grant of 5% and 10% from the date the option was granted to the end of the option term. The 5% and 10% rates of appreciation are specified by the rules of the Securities and Exchange Commission and do not represent the Company's estimate or projection of future Common Stock prices. The Company does not necessarily agree that this method properly values an option. Actual gains, if any, on option exercises are dependent on the future performance of the Company's Common Stock and overall market conditions.

The value realized is calculated based on the sale price of the Company's Common Stock as reported by the Nasdaq National Market on the date of exercise minus the exercise price of the option, and does not necessarily indicate that the optionee sold such stock.

(2)
The Company has not granted any stock appreciation rights and its stock plans do not provide for the granting of such rights.

(3)
The market value of underlying securities is based on the difference between the closing price of the Company's Common Stock on September 28, 2001 of $28.40 (as reported by Nasdaq National Market) and the exercise price.

Director Compensation

        In fiscal year 2001, members of the Board of Directors who were not employees of the Company received $16,000 plus $1,500 per meeting attended plus $750 per committee meeting attended and were reimbursed for their expenses incurred in attending such meetings.

        The Company's 1990 Directors' Stock Option Plan (the "Directors' Option Plan") was adopted by the Board of Directors on December 8, 1989 and was approved by the stockholders on March 29, 1990. The Directors' Option Plan was amended by the Board of Directors on January 25, 1996, and the amendment was approved by the stockholders on March 20, 1996. The Directors' Option Plan terminated on December 8, 1999 and no further options will be granted under this plan. The Directors' Option Plan provided for the automatic and non-discretionary grant of a non-statutory stock options to purchase 20,000 shares of the Company's Common Stock to each non-employee director on the later of the effective date of the Directors' Option Plan or the date on which such person became a director. Thereafter, during the term of the Directors' Option Plan, each non-employee director was automatically granted a non-statutory stock option to purchase 5,000 shares of Common Stock on the date of and immediately following each Annual Meeting of Stockholders at which such non-employee director was reelected to serve on the Board of Directors, if, on such date, he or she had served on the Board for at least three months. Such plan provided that the exercise price shall be equal to the fair market value of the Common Stock on the date of grant of the options.

        Two non-employee directors each have been granted options to purchase 65,000 shares of the Company's Common Stock under the Directors' Option Plan at a weighted average exercise price of $11.62 per share. One non-employee director has been granted options to purchase 45,000 shares of

-6-



the Company's Common Stock under such plan at a weighted average exercise price of $13.73 per share. One non-employee director has been granted options to purchase 30,000 shares of the Company's Common Stock under such plan at a weighted average exercise price of $21.33 per share. As of the fiscal year ended September 29, 2001, options have been granted to purchase 295,000 shares under the Directors' Option Plan.

        The Company's 1998 Directors' Stock Option Plan (the "1998 Directors' Plan") was adopted by the Board of Directors on November 24, 1998 and was approved by the stockholders on March 17, 1999. 100,000 shares of Common Stock were reserved for issuance thereunder. Under the terms of the 1998 Directors' Plan, the number of shares reserved for issuance thereunder is increased each year by the number of shares necessary to restore the total number of shares reserved to 100,000 shares. The 1998 Director's Plan replaced the Directors' Option Plan which expired on December 8, 1999. Like its predecessor, the 1998 Directors' Plan provides for the automatic and non-discretionary grant of a non-statutory stock options to purchase 20,000 shares of the Company's Common Stock to each non-employee director on the date on which such person becomes a director. Thereafter, each non-employee director will be automatically granted a non-statutory stock option to purchase 5,000 shares of Common Stock on the date of and immediately following each Annual Meeting of Stockholders at which such non-employee director is reelected to serve on the Board of Directors, if, on such date, he or she has served on the Board for at least three months. Such plan provides that the exercise price shall be equal to the fair market value of the Common Stock on the date of grant of the options.

        Four non-employee directors have each been granted options to purchase 10,000 shares of the Company's Common Stock under such plan at a weighted average exercise price of $56.88. One non-employee director has been granted options to purchase 25,000 shares of the Company's Common Stock under such plan at a weighted average exercise price of $68.20 per share. As of the fiscal year ended September 29, 2001, options have been granted to purchase 70,000 shares under the 1998 Directors' Plan.

        The following table shows options granted to each director of the Company during the last fiscal year. All options were granted under the 1998 Directors' Plan, except for the options granted to Dr. Couillaud and Mr. Quillinan, which were granted under the Company's 1995 Stock Plan.

Other Employee Benefit Plans

Employee Retirement and Investment Plan and Supplementary Retirement Plan

        Effective January 1, 1979, the Company adopted the Coherent Employee Retirement and Investment Plan. Employees become eligible to participate after completing one year of service. Under this plan, the Company will match employee contributions to the plan up to a maximum of 6% of the individual's employee earnings. An employee is not entitled to any part of the Company's contribution until the completion of his or her third year of employment. After the end of the third year of employment, 20% of the Company's contribution vests. Thereafter, an additional 20% of the Company's contribution vests at the end of each year of completed service until the end of the seventh year of employment when such contributions become 100% vested. Effective as of 1985, the plan was amended and restated to conform the plan to new regulations and to qualify under Section 401(k) of the Internal Revenue Code of 1986, as amended to permit employees to make contributions to the plan from their pre-tax earnings. Effective January 1, 1990, the Company adopted the Supplementary Retirement Plan which provides that certain senior management may contribute income to a trust fund. The Company will match such contributions up to 6% of the participant's income. Such contributions are subject to the same vesting requirements as contributions made under the Employment Retirement and Investment Plan.

Variable Compensation Plan

        The Company's Variable Compensation Plan provides for the payment of quarterly cash bonuses to members of management designated by the Board of Directors determined by a formula based on improvements of pre-tax profits and asset management over preset threshold levels, sales growth and rate of profitability for each operating group or business unit.

shares of Common Stock were available for issuance to employees of the Company and its designated subsidiaries who are customarily employed for at least twenty hours per week. The purpose of the Incentive Plan is to enhance an employee's proprietary interest in the Company and to create an incentive for the Company's success.

        The Incentive Plan provides for the quarterly distribution of cash or Common Stock, at the election of each participant, based upon the quarterly profitability of the Company. The amount of cash or number of shares of Common Stock distributed to each participant is determined by dividing a participant's "incentive compensation" by the fair market value of the Company's Common Stock at the end of each three-month period.

Employee Stock Purchase Plan

        The Company's Employee Stock Purchase Plan (the "Purchase Plan") was adopted by the Board of Directors and approved by the stockholders in 1980. A total of 4,575,000 shares of Common Stock have been reserved under the Purchase Plan, and as of the end of fiscal year 2001, 1,423,267 shares of Common Stock remained available for issuance thereunder. The Purchase Plan permits employees who are employed for at least twenty hours per to purchase Common Stock of the Company, through payroll deductions at the lower of 85% of the fair market value of the Common Stock at the beginning or at the end of each six-month period. Payroll deductions may not exceed 10% of an employee's compensation. The Purchase Plan provides for two offerings during each fiscal year, each having a duration of six months.
