quorum. Abstentions will not be counted either in favor of or against the election of the nominees or other proposals. Under the rules of the National Association of Securities Dealers, brokers
holding stock for the accounts of their clients who have not been given specific voting instructions as to a matter by their clients may vote their clients' proxies in their own discretion.

Proxies

The Company's Board of Directors currently consists of seven members. The six nominees listed on page 2 are proposed for election at the Annual Meeting of
Shareholders, to hold office until the next Annual Meeting of Shareholders or until their successors are elected and qualified. It is intended that the accompanying proxy will be voted in favor of the
following persons to serve as directors unless the shareholder indicates to the contrary on the proxy. In the event that any nominee is unable or declines to serve as director at the time of the
Annual Meeting, the proxies will be voted for any nominee who shall be designated by the present Board of Directors to fill the vacancy. In the event that additional persons are nominated for election
as directors, the proxy holders intend to vote all proxies received by them in such a manner as will assure the election of as many of the nominees listed below as possible and, in such event, the
specific nominees to be voted for will be determined by the

Described below are the compensation plans that have been established by the Company that provide for the payment of cash or noncash compensation to certain
directors and executive officers of the Company. The amounts paid to the listed individuals and group are also disclosed.



Executive officers and key management are eligible to participate in an incentive plan which provides for the payment of bonuses after the end of each fiscal
year based on net profit achieved prior to the cost of the Management Incentive Plan (MIP). No bonus is paid if net profit is less than 75% of planned profit for the year. Actual bonuses vary linearly
with profit and are paid as a percent of base salary. Should planned profits be achieved, bonuses paid would range from 40% of base salary for the Chief Executive Officer to 30% for Vice Presidents
and 12% for other key management. This incentive plan is proposed annually by the Compensation Committee and approved by the Board of Directors and is subject to revision. Although the criteria
indicated above were not met for the year ended June 30, 2000, the Board of Directors exercised its discretion to make distributions to certain officers.



All employees are eligible to participate in this plan on the first day of the month after their date of hire. An employee is able to defer up to 15% of his or
her pre-tax annual salary up to a maximum of $9,500 under the salary deferral provisions of the Plan. At the discretion of the Board of Directors, the first $300 of the employee's deferral
shall be matched by the Company dollar for dollar. The Company shall match $.50 for each $1.00 an employee defers between $300 and 6% of the employee's compensation. Any deferral in excess of 6% of
the employee's compensation shall not be matched. The employee's deferrals and the Company's contributions are invested, at the employee's direction, in one or more investment funds.

Employees
are 100% vested in their salary deferrals, the Company's contributions, and all earnings thereon. At any time after an employee has reached age 591/2, an
employee may withdraw all or a portion of the funds. In addition, the employee may borrow from the Plan and may receive a distribution of benefits in the event of financial hardship. Upon termination
of employment, death or disability, the employee or beneficiary will receive a lump sum payment of benefits. Executive officer compensation, as related in the Cash Compensation table, includes any
salary deferral under the Plan.

During
the period ending June 30, 2000, the Company's contributions to the executive officers named in the Cash Compensation table and all employees as a group were:

The Company has two active stock option plans: the Nonemployee Directors' Stock Option Plan and the 1992 Stock Option Plan for key employees. The Nonemployee
Directors' Stock Option Plan provides for the grant of options to purchase up to 320,000 common shares to outside directors of the

6

---

Company. Options are granted at the fair market value of the stock on the date of grant and vest over a four-year period. The maximum term of an option may not exceed six years.

Under
the terms of the 1992 Stock Option Plan, all present and future key employees who, at the time the options are granted, are regular full-time employees of the
Company, are eligible to participate. The number of shares that may be granted under the 1992 Option Plan is 1,400,000, of which no shares remain available for grant as of September 5, 2000.
The option price and award are determined by the Compensation Committee of the Board of Directors. Subject to the provisions of the 1992 Option Plan, the Board of Directors determines the terms and
provisions of the option agreements and the number of shares of common stock subject to each option.

During
fiscal year 2000 the following options to purchase common stock were granted at fair market value to named executive officers:

Compliance With Section 16(a) of the Securities Exchange Act of 1934

Under the securities laws of the United States, the directors and executive officers of the Company and any persons holding more than ten percent (10%) of the
Company's common stock are required to report their initial ownership of the Company's common stock and any subsequent changes in that ownership to the Securities and Exchange Commission (the "SEC").
Specific filing deadlines of these reports have been established and the Company is required to disclose in this proxy statement any late filings during fiscal years 1999 and 1998. To the best of our
knowledge, all of the filing requirements have been satisfied except that Mr. Dick Johnson was late in filing a Form 4 to reflect his February 2000 stock option exercise. In
making these statements, we have relied solely on written representations of our directors and executive officers and any ten percent (10%) holders and copies of the reports that they filed with the
SEC.

PROPOSAL NO. 2:       APPROVAL OF AMENDMENT TO  1992 STOCK OPTION PLAN

At the meeting the shareholders will be requested to approve an amendment to the 1992 Stock Option Plan (the "1992 Option Plan"). The amendment is to increase
the Company's common stock subject to the 1992 Option Plan from 1,400,000 shares to 1,900,000 shares. The Board believes stock options are essential to attracting and retaining key employees and
encouraging them to devote their full efforts toward the success of the Company. The Board adopted the 1992 Option Plan at its meeting held on February 18, 1992, and recommends approval of this
amendment.

Description of the Option Plan

The following description is qualified in its entirety by reference to the 1992 Option Plan itself, which can be obtained from the Company.

The
1992 Option Plan, if the amendment is approved by the shareholders, will reserve 1,900,000 shares of the Company's common stock for issuance pursuant to stock options to be
granted thereunder. Incentive stock options and/or non-qualified stock options may be granted to eligible employees of the Company during the ten-year term of the 1992 Option
Plan.

Option
grants to non-officer employees may be made by the entire Board or by a committee of two or more Board members. Option grants to officers shall be made by the
entire Board if all Board members are "disinterested persons" as that term is defined in Rule 16-b-3 of the SEC, or by a committee of two or more directors, all of whom
must be "disinterested persons." The Board has delegated to the Compensation Committee the function of granting options to officers, including the determination of which officers will receive options
and the size of such options.

The
Committee will establish the time or times at which options may be exercised and whether all of the options may be exercisable at one time or in increments over time. The option
price shall be set by
the Committee at the time of granting of an option. For incentive stock options, the option price may not be less than the fair market value of the Company's stock on the date of grant. For
non-qualified stock options, the option price may be less than, equal to, or greater than the fair market value of the Company's stock on the date of grant. The Company can reset the price
of any stock option after the original grant and before exercise. In the event of stock dividends, splits, and similar capital changes, the 1992 Option Plan provides for appropriate adjustments in the
number of shares available for options and the number and option prices of shares subject to outstanding options.

The
terms of each option shall be no more than six years from the date of grant. Generally, options expire thirty days following termination of employment (but in no event later than
the date of expiration of the term of the option as set forth in the option agreement), except in the case of permanent disability or death and except for discharge for misconduct, willfully or
wantonly harmful to the Company. In the case of termination due to death or permanent disability, the option terminates ninety days (or such shorter period as is specified in the option agreement)
from the date the employee ceases work as a result of death or disability (but in no event later than the date of expiration of the term of such option as set forth in the option agreement). The Board
has the authority to extend the foregoing expiration dates of any outstanding option in circumstances it deems appropriate, provided that no such extension can go beyond the original term of such
option (e.g., six years from grant date). Each option vests over a four-year period, with 25% vesting on each of the first four anniversaries of the Grant Date.

The
purchase price of option shares may be paid in cash. Option holders may also exercise their options by surrendering shares of the Company's common stock owned by the Optionee.
Shares used to pay the exercise price shall be valued at their fair market value on the exercise date. For non-qualified

options, the option holder must also pay the Company, at the time of purchase, the amount of federal, state, and local withholding taxes required to be withheld by the Company. Option holders may pay
these federal, state, and local withholding taxes by turning in shares of the Company's common stock, valued at fair market value.

In
the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, the Board shall provide for
the Optionee to have the right to exercise the Option as to all of the Optioned Stock, including Shares as to which the Option would not otherwise be exercisable. The Board shall notify the Optionee
that the Option shall be fully exercisable for a period of thirty (30) days from the date of such notice, and the Option will terminate upon the expiration of such period.

The
Board has the right to substitute or assume options in connection with mergers, reorganizations, separations, or other transactions to which Section 424(a) of the Internal
Revenue Code of 1986, as amended, (the "Code") applies, provided such substitutions and assumptions are permitted by Section 424 of the Code and the regulations promulgated thereunder. The
number of shares reserved for the 1992 Option Plan may be increased by the corresponding number of options assumed and, in the case of a substitution, by the net increase in the number of shares
subject to options before and after the substitution.

The
1992 Option Plan may be modified, amended, or terminated by the Board of Directors except with respect to options granted prior to such action. Notwithstanding the foregoing,
shareholder approval is required for any amendment with increases the number of shares subject to the 1992 Option Plan (other than in connection with automatic adjustments due to changes in
capitalization or the assumption of options in connection with mergers or acquisitions) or which otherwise requires shareholder approval pursuant to Rule 16b-3 of the SEC.

The
issuance of stock upon exercise of options already granted is subject to securing shareholder approval of 1992 Option Plan and the registration with the SEC of the shares reserved
thereunder.

The
options are nonassignable except by will or by the laws of descent and distribution.
