The Compensation Committee ("Committee") for fiscal 1998 was comprised of Directors James L. Linderholm, Chairman; Dale L. Young, Secretary; John J. Brasch; and Robert W. Allington (a non-voting member). Messrs. Linderholm, Young, and Brasch are non-employee directors. The committee reviews and recommends to the Board the direct and indirect compensation and employee benefits of the Chairman of the Board, the President, and other elected officers of the Company. The Committee also acts as the stock option committee. Compensation Principles. The philosophy of the Company with regard to executive compensation is to design executive compensation programs in a manner intended to enhance Company performance and shareholder value by achieving the following objectives: - Provide reasonable and appropriate levels of compensation that will attract, motivate, and retain highly qualified executives; - Integrate compensation with the Company's business and strategic plans; - Reward both business and individual performance; and - Encourage stock ownership by executives, thereby aligning executive compensation with shareholder value. Executive Officer Compensation Program. The Company's compensation program for executive officers consists of annual salary, bonuses, and periodic grants of options to purchase the Company's Common Stock. In addition, executives are entitled to customary benefits, including medical, vacation, and retirement benefits as well as participation in the Company's 401(k) matching contributions plan, that are generally available to employees of the Company. Salary and bonus payments are designed to reward current and past performance, while the stock options are intended to provide incentives for long-term future performance and are directly linked to the interests of the shareholders because the value of options will increase or decrease based directly upon the future price of the Company's Common Stock. In 1997, the Company, upon the recommendation of the Compensation Committee, engaged Burgess & Associates, a management consulting firm, to review the entire executive compensation system of the Company and to 1) recommend a market-based salary and short-term incentive program for all elected officers and 2) develop a long-term incentive program for the officer group. In January, 1998, the Compensation Committee adopted the recommendations from the Burgess report and those recommendations were subsequently adopted by the Board of Directors. The new compensation plan, based upon the Burgess report, is designed to require specific performance in revenues and operating income for annual incentive or bonus compensation as well as for the granting of stock options. Base Salary. The base salary levels of the Company's executives are evaluated periodically by the Committee in view of specific job responsibilities and prevailing salary levels of companies of comparable size and complexity. The Burgess report contains such an evaluation and based upon the recommendations from the Burgess report the Committee recommended a mid-year adjustment to the salary of one officer, Douglas Grant, the Company's President and Chief Operating Officer. The Committee, in addition to the Burgess report, also utilizes the Ernst & Young National Survey of Executive Compensation, the Wyatt Data Service ECS survey, and Compensation in the Accounting/Financial Field published by Abbott, Langer & Associates as aids in determining whether executive salaries are appropriate and competitive. Annual Bonus Compensation. The Committee believes and the Burgess report also concluded that cash incentives, in the form of bonuses and stock options, are warranted for the achievement of Company goals and corporate and individual performance. The short-term incentive bonus and stock option plan adopted by the Committee and the Board of Directors in January, 1998 are based upon the achievement of certain targeted revenue and operating income goals. The target goals were set for fiscal years 1998, 1999, and 2000. Depending upon a covered executive's area of responsibility, the executive could receive 100% of the incentive compensation of the maximum revenue goal was met or if the maximum operating income goal was met. If both maximum goals were met, the executive could receive a maximum of 150% of the targeted incentive compensation. No benefits under the short-term incentive bonus plan were earned during fiscal 1998. The Board also adopted a change in control plan which offers certain financial benefits in the case of a change or control of the Company. Currently, the President, Vice President of Sales and Marketing, and the Chief Financial Officer are covered under the change in control plan. 7 Stock Option Compensation. The six executive officers of the Company were granted options totaling 154,595 shares in fiscal 1998, all of which are performance based under the new plan described above. Twenty percent of the options vest and are exercisable on the date of grant and twenty percent of the remaining eligible options will vest and will become exercisable for each year that the Company achieves 100 percent of the targeted revenue and operating income goals, as described earlier. A proportional amount of the twenty percent will vest and become exercisable based upon the extent to which the revenue and operating income goals are met, so long as revenue and operating incomes are at least 40% of the targeted goals for the particular fiscal year. If revenue and operating income exceed the targeted goals for the fiscal year by any percent up to 150%, a proportional amount of the option greater than 20% will vest and will become exercisable. The revenue and operating income targeted goals are the same for each covered executive as those set for the incentive bonus compensation. As described earlier, one of the executive officers received a salary adjustment in fiscal 1998 based upon the recommendations contained in the Burgess report. No other executive officer received a salary increase in fiscal 1998. Overall Review. Fiscal 1998 has been an important year for this Company with the construction of the major addition to and the renovation of the Superior Street facility to effect the consolidation of the two Lincoln operating divisions at one site. The acquisition of Geomation, Inc., STIP Siepmann und Teutscher GmbH in Germany, and the limited partnership agreement negotiated with AMJ Equipment Corporation should strengthen and expand several of our product lines. The Committee believes that the executive officers of the company are positively addressing this Company's problems and opportunities and that the compensation for the executive officers is fair and reasonable for both the officers and the shareholders of the Company.

The following performance graph compares the performance of the Company's Common Stock to the Standard and Poor's 500 Stock Index and the NASDAQ peer group. The industry peer group, selected by the Company, is comprised of the 98 companies whose stock is traded on NASDAQ and are included in the Standard Industrial Code Classification No. 382 entitled "Measuring and Controlling Devices".

The Company's defined contribution retirement plan includes a 401(k) provision that covers all employees meeting age and service requirements. Significant provisions of the plan include the following: (i) an employee may reduce his or her salary by up to 12 percent, and the Company will match the reduction, up to 10 percent, with a 20 percent matching contribution; (ii) the Company's profit sharing contribution to the plan is equal to approximately 7 percent of its net earnings before income taxes; (iii) the Company's aggregate contribution to the plan is limited to 15 percent of the aggregate compensation of the plan participants; (iv) participants vest 20 percent of employer profit sharing and employer 401(k) matching contributions after three years of service and 20 percent per year thereafter until 100 percent vested. Management and administrative costs of the plan are borne by the Company. For fiscal year 1998, amounts contributed to the plan for the chief executive officer and the four other most highly compensated executive officers of the Company are set forth as part of the table appearing in the Executive Compensation section.
