(2) An appreciation in stock price is required for optionees to receive any gain. A stock price appreciation of zero percent would render the options without value to the optionees.

The disclosure assumes the options will be held for the full ten-year term prior to exercise. Such options may be exercised prior to the end of such ten-year term. The actual value, if any, an executive officer may realize will depend upon the excess of the stock price over the exercise price on the date the option is exercised. There is no assurance that appreciation, if any, in the stock price will occur at the rates shown in the table. 9

Edgar Hendrix and Paul K. Lackey, all of whom are independent directors who are not employees and who qualify as non-employee directors for purposes of Rule 16b-3 adopted under the Securities Exchange Act of 1934. The Committee is responsible for evaluating the performance of the Chief Executive Officer and the Chief Financial Officer ("Named Executive Officers"), determining the compensation of the Named Executive Officers and administering the Company's stock option plan under which grants may be made to employees of the Company. The Committee has furnished the following report on executive compensation for the fiscal year ending May 31, 2002. The annual compensation package of the Named Executive Officers primarily consists of (i) a cash salary which reflects the responsibilities relating to the position and individual performance, (ii) variable performance awards payable in cash and tied to the individual's and the Company's performance against pre-established financial measures and (iii) long-term stock-based incentive awards which strengthen the relationship between the interests of the Named Executive Officers and the interests of the Company's stockholders. In determining the level and composition of compensation for each Named Executive Officer, the Committee takes into account various qualitative and quantitative indicators of each officer's performance. The Committee's objectives in determining compensation are to allow the Company to attract, motivate and retain the executive personnel necessary for the Company's success and to provide an executive compensation program comparable to that offered by the companies with which the Company competes for such management personnel. Although no specific target has been established, the Committee generally seeks to set salaries at or below the average of a range in comparison to peer group companies based upon experience of the Named Executive Officers. In setting salaries, the Compensation Committee considers its peer group to be certain companies with market capitalizations similar to that of the Company. This peer group does not necessarily include the companies comprising the Standard and Poor's Engineering and Construction Index reflected in the performance graph in this Proxy Statement, which is the industry categorization the Company has been placed in by its market makers. In evaluating the performance of the Named Executive Officers, the Committee takes into consideration such factors as total operating income (TOI) based on a fiscal budget plan which is reviewed by the Committee. Base compensation is established through negotiation between the Company and the Named Executive Officer at the time the executive is hired, or named to the executive position, and then subsequently (in general annually) when such officer's base compensation is subject to review or reconsideration. Base salaries after the initial year will be determined by the Compensation Committee after review of the officer's performance. In establishing or reviewing base compensation levels for each Named Executive Officer, the Committee, in accordance with its general compensation policy, considers numerous factors, including the responsibilities relating to the position, the qualifications of the executive and the relevant experience the individual brings to the Company, strategic goals for which the executive has responsibility, and compensation levels of other companies at a comparable stage of development that compete with the Company for business and executive talents. No predetermined weights are given to any such factors. The salaries for each of the Named Executive Officers in fiscal year 2002 were set taking into account these factors in accordance with the Company's general compensation policy discussed above. In addition to each Named Executive Officer's base compensation, the Committee may award cash bonuses and/or grant awards under the Company's Stock Option Plan to Named Executive Officers depending on the extent to which certain defined personal and corporate performance goals are achieved. Such corporate performance goals include revenue and earnings targets of the Company, as discussed above. The Chief Executive Officer's compensation is the responsibility of the Compensation Committee. Based upon the Compensation Committee's assessment of Mr. Vetal's ability to effectively lead the Company into the future as determined by his past performance and experience with the Company's business and markets, the Compensation Committee determined that Mr. Vetal's compensation package would consist of the following: (i) annual base salary of $279,935 and (ii) annual bonus target of 79% of annual salary based upon the Company achieving specific TOI targets as discussed above. For the past year, the Chief Executive Officer's bonus resulted in a 58.25% of salary bonus as determined by the Compensation Committee. 11

The Chief Financial Officer's compensation is the responsibility of the Compensation Committee. Based upon the Compensation Committee's assessment of Mr. Hall's ability to effectively lead the Company into the future as determined by his past performance and experience with the Company's business and markets, the Compensation Committee determined that Mr. Hall's compensation package would consist of the following: (i) annual base salary of $194,888 and (ii) annual bonus target of 50% of annual salary based upon the Company achieving specific TOI targets as discussed above. For the past year, the Chief Financial Officer's bonus resulted in a 42.95% of salary bonus as determined by the Compensation Committee. Equity incentives are not limited to executive officers. Grants of stock options are made to management and staff of the Company in amounts determined by the Compensation Committee. The amounts of such grants are determined based on the individual employee's position with the Company and his or her potential ability to beneficially impact the performance of the Company. By giving management and staff a stake in the financial performance of the Company, the Compensation Committee's goal is to provide incentives to these employees of the Company to enhance the financial performance of the Company and, thus, stockholder value. Salaried employees of the Company with grade levels of 27 or greater, including the Named Executive Officers, are eligible to receive long-term stock based incentive awards under the Company's Stock Option Plan as a means of providing such individuals with a continuing proprietary interest in the Company. Such grants further the mutual interests of the Company's employees and its stockholders by providing significant incentives for such employees to achieve and maintain high levels of performance. The Company's Stock Option Plan enhances the Company's ability to attract and retain the services of qualified individuals. Factors considered in determining whether such awards are granted includes the employee's position in the Company, his or her performance and responsibilities, the number of options, if any, currently held, and the vesting schedule of any such options. The Committee has adopted an established schedule for the issuance of options, with designated option grants for specific salary grades over a three-year period.
