          Mr. Vetal for his role as President and Chief Executive Officer, a
          position he assumed in March 1999.

(1)  Options granted during the year ended May 31, 2001 vest equally over five
     years of service and expire ten years from date of grant.

(2)  Options for Mr. Davis in fiscal year 2001 were granted at exercise prices
     of $4.81 (as to 15,000 shares) and $4.25 (as to 5,000 shares) with
     expiration dates of July 11, 2010 and October 18, 2010, respectively.

(3)  Options for Mr. Newmeister in fiscal year 2001 were granted at exercise
     prices of $4.81 (as to 15,000 shares) and $4.25 (as to 5,000 shares) with
     expiration dates of July 11, 2010 and October 18, 2010, respectively.

(4)  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 Securities and Exchange Commission
     requires disclosures of the potential realizable value or present value of
     each grant.  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.

Report of the Compensation Committee of the Board of Directors

     The Compensation Committee ("Committee") of the Board of Directors of the
Company currently consists of Hugh E. Bradley, I. 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,
2001.

     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 2001 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.

                                       11


     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 $228,190 and
(ii) annual bonus target of 70% 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 20% of salary bonus as determined by the
Compensation Committee.

     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 $172,371 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 20% 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 3-year period.

     The report of the Compensation Committee shall not be deemed incorporated
by reference by any general statement incorporating by reference this Proxy

fees of $90,000 and fees for quarterly reviews of $9,300.

     This report of the Audit Committee shall not be deemed incorporated by

Compliance with Section 16(a)

     Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's directors and officers, and persons who own more than ten percent
of the Common Stock, to file initial reports of ownership and reports of changes
in ownership (Forms 3, 4 and 5) of the Common Stock with the Securities and
Exchange Commission (the "SEC") and the NASDAQ Stock Market. Officers, directors
and greater than 10 percent stockholders are required by SEC regulations to
furnish the Company with copies of all such forms that they file.

     To the Company's knowledge, based solely on the Company's review of the
copies of such reports received by the Company and on written representations by
certain reporting persons, the Section 16(a) filing requirements were satisfied
by the Company's directors, officers and ten percent stockholders, except for
one transaction for the granting of Phantom Stock (SARs) by Paul K. Lackey not
timely reported on Form 4.
