                               BOARD OF DIRECTORS

     The Board of Directors has the responsibility for establishing broad
corporate policies and for the overall performance of the Company, although it
is not involved in day-to-day operating details. The Board meets regularly
throughout the year, including the annual organization meeting following the
Annual Meeting of Shareholders, to review significant developments affecting the
Company and to act upon matters requiring Board approval. It also holds special
meetings as required from time to time when important matters arise requiring
Board action between scheduled meetings. During the last fiscal year, the board
met four times.

     The Board of Directors has established Compensation and Audit Committees to
devote attention to specific subjects and to assist it in the discharge of its
responsibilities. The functions of these committees, their current members, and
the number of meetings held during the last fiscal year are described below.

     The Compensation Committee consists of Messrs. Campbell and Brooks. Its
function is to recommend the compensation to be paid to the President and
certain other employees, and for the development of policies on employee
compensation and benefits. The Compensation Committee met once during the fiscal
year ended March 31, 2002.

     The Audit Committee consists of Messrs. Campbell and Brooks. The Audit
Committee operates under a written charter adopted by the Company's Board of
Directors. The functions of the Audit Committee are to appoint the independent
public accountants of the Company on an annual basis, discuss and review the
scope and the fees of the prospective annual audit and review the results
thereof with the independent public accountants, review and approve non-audit
services of the independent public accountants, review compliance with existing
major accounting and financial policies of the Company, review the adequacy of
the financial organization of the Company and review management's procedures and
policies relative to the adequacy of the Company's internal accounting controls
and compliance with federal and state laws relating to accounting practice. The
Audit Committee met twice during the fiscal year ended March 31, 2002.

     The Company does not have a nominating committee. The functions customarily
attributable to a nominating committee are performed by the Board of Directors
as a whole.

     No director attended fewer than 75 percent of the aggregate of the total
number of meetings of the Board of Directors and the total number of meetings
held by all committees of the Board on which he served.

     Each non-employee director will be compensated separately for service on
the Board and is reimbursed for expenses to attend Board meetings. Members of
the Audit and Compensation Committees are not compensated separately for service
on those committees. In addition, non-employee directors participate in the
Outside Director Stock Option Plan. See "Executive Compensation - Compensation
of Directors."

                              ELECTION OF DIRECTORS

     At the Meeting, four directors are to be elected. Each director will be
elected for a one-year term or until his successor is elected and qualified.

     Shares represented by properly executed proxies will be voted, in the
absence of contrary indication therein or revocation thereof by the shareholder
granting such proxy, in favor of the persons named below as directors, to hold
office for the term stated in the preceding paragraph. The person named as proxy
in the enclosed proxy has been designated by management and intends to vote for
the election to the Board of Directors of the persons named below, each of whom
is now a director of the Company. If the contingency should occur that any such
nominee is unable to serve as a director, it is intended that the shares
represented by the proxies will be voted, in the absence of contrary indication,
for any substitute nominee that management may designate. Management knows of no
reason why any nominee would be unable to serve. The information presented
herein with respect to the nominees was obtained in part from the respective
persons, and in part from the records of the Company.

Compensation of Directors

     On October 3, 1996, the Company adopted a new nonqualified performance
stock option plan for the benefit of the Company's outside Directors. The plan
provides that the outside Directors will receive grants to be determined and
approved by the Company's inside directors and not to exceed 20,000 options per
year per director. Under the terms of the plan, the options are exercisable for
a term of ten years, and during such term are exercisable as follows: 25% after
each year, and 100% anytime after the fourth year until the end of the tenth
year. The purchase price of the common stock will be equal to 100% of the
closing bid price of the common stock on the over-the-counter market on the date
of grant.

     On July 2, 2001, the Company's two outside directors were granted options
to purchase 4,000 shares of common stock at $4.55 per share. The Company's two
inside directors each were granted options to purchase 4,000 shares of common
stock at a price of $4.55 per share.

     Currently, all outside directors receive cash compensation of $500 for each
Board of Directors meeting attended in person.

Incentive Stock Option Plans

     The Company has adopted three incentive stock option plans, approved by the
shareholders of the Company in September 1984, October 1989 and November 1993,
respectively, for the benefit of the Company's employees. The plans are
administered by the non-participating members of the Board of Directors, who
select the optionees and determine the terms and conditions of the stock option
grant. The exercise price for options granted under the plans cannot be less
than the fair market value of the stock at the date of grant or 110% of such
fair market value with respect to options granted to any optionee who holds more
than 10% of the Company's common stock. Options are not exercisable until one
year after the date of grant and expire five years after the date of grant. All
outstanding options are subject to vesting provisions whereby they become
exercisable over a four-year period. The plans authorize options to purchase up
to 200,000, 300,000 and 300,000 shares of common stock, respectively.

     On October 21, 1999, the Company adopted a new stock compensation plan. The
purpose of the plan is to encourage ownership of the Common Stock of the Company
by certain officers, directors, employees and certain advisors of the Company in
order to provide incentive to promote the success and business of the

                                       6


Company. A total of 300,000 shares of Common Stock have been reserved for
issuance under the plan and are subject to terms as set by the Compensation
Committee of the Board of Directors at the time of grant.

     As of March 31, 2002, options to purchase a total of 328,035 shares were
outstanding, at exercise prices ranging from $3.75 to $7.00 per share. Further,
as of March 31, 2002, options to purchase an aggregate of 271,395 shares
remained available for grant under the Company's stock option plans. The plan
adopted in September 1984 was terminated effective June 1, 1993. Options were
granted during the fiscal year ended March 31, 2002, pursuant to the Company's
incentive stock option plans, to each of the Company's executive officers.
Options to purchase 6,000 shares at $4.55 per share were granted to Mr. Steven
W. Peterson, Vice President-Finance. Mr. Luke R. Schmieder, President, and Mr.
