returned properly executed and dated, the shares represented thereby will be
voted at the Annual Meeting. If a choice is specified in the proxy, the shares
represented thereby will be voted in accordance with such specification. If no
specification is made, the proxy will be voted FOR the action proposed. Any
stockholder giving a proxy has the right to revoke it any time before it is
voted by filing with the Secretary/Treasurer of the Company a written
revocation, or by filing a duly executed proxy bearing a later date, or by

holders at the Annual Meeting. The three nominees for election as Class III
Directors who receive the highest number of votes therefore at the Annual

    Company on December 31, 2001 at $0.87 per share closing price.

COMPENSATION OF DIRECTORS

     Directors who are employees of the Company do not receive additional
compensation for serving as Directors. Effective December 15, 2000, non-employee
directors receive a stock option grant of 700 shares of Common Stock of the
Company per meeting attended, as approved by the Compensation Committee on
December 14, 2000. The Directors of the Company are reimbursed for out-of-pocket
expenses incurred in attending meetings of the Board of Directors or any
committees thereof.

COMPENSATION COMMITTEE INTERLOCKS

     For the past twelve months, the members of the Compensation Committee
consisted of Mr. Copeland, Mr. Carroll, Mr. DiPrete and Mr. Haslinger, each of
whom is a non-employee Director of the Company. Mr. Carroll receives consulting
and sales representation fees as disclosed in the Certain Relationships and
Related Transactions section of this document. Mr. Haslinger is a licensee of
the Company for the territory of the Philippine Islands, but has not received
any fees or revenue from the Company other than the reimbursement of travel
expenses for costs directly related to this territory.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The compensation of the Company's Executive Officers is determined by the
Compensation Committee of the Board of Directors.

     The Committee's compensation philosophy is to provide competitive forms and
levels of compensation compared to industrial companies of similar size and
business area. This philosophy is intended to assist the

                                        7


Company in attracting, retaining and motivating executives with superior
leadership and management abilities. Consistent with this philosophy, the
Committee determines a total compensation structure for each officer, consisting
primarily of salary, bonus and stock options. The proportions of the various
elements of compensation vary among the officers depending upon their levels of
responsibility.

     The Committee establishes salaries at a level intended to be competitive
with the average salaries of Executive Officers in comparable companies with
adjustments made to reflect the financial health of the Company. Bonuses are
intended to provide executives with an opportunity to receive additional cash
compensation, but only if they earn it through Company and individual
performance.

     Long-term incentives are provided through stock options granted under the
Company's Stock Option Plan. The stock options represent an additional vehicle
for aligning management's and stockholders' interest, specifically motivating
executives to remain focused on the market value of the Common Stock in addition
to earnings per share and return on equity goals.

     The Committee, subject to any employment agreements in effect with its
Executive Officers, reviews and recommends to the Board of Directors for
approval the salaries, bonuses and long-term incentives of the Company's
officers, including its most highly compensated Executive Officers. In addition,
the Committee grants stock options under the Company's Stock Option Plan to
Executive Officers and other selected employees, Directors and to consultants,
and otherwise administers the Company's Stock Option Plan.

     With respect to Chief Executive Officer compensation, Mr. Nicholson's base
salary for 2001 was $131,250. Mr. Nicholson's base salary is determined by his
Employment Agreement which entitles him to a minimum annual base salary of
$144,000. See "Employment Agreements." However, Mr. Nicholson has reduced his
base salary in each of the six preceding years. He is scheduled to be paid an
annual minimum base salary of $131,250 until his scheduled retirement in July
2002. Mr. Nicholson will continue to accept a reduced base salary until such
time as the Company's profitability permits payment of the $144,000 annual
minimum base salary provided for in his Employment Agreement. In July 2002, Mr.
Nicholson will become an outside consultant to the Company, pursuant to the
terms of his Consulting Agreement.

     The Committee is also responsible for recommending to the Board of
Directors bonus amounts payable to Mr. Nicholson, the Chief Executive Officer.
Any bonuses payable will be determined by the Committee, based on the same
elements and factors relating to the other Executive Officers of the Company. As
the founder and the largest beneficial owner (21.19% of total shares of common
stock outstanding) of the Company, Mr. Nicholson has a significant portion of
his wealth invested in the Company's stock. Mr. Nicholson's level of stock
ownership continues to provide a strong link between Company performance and the
resulting rewards.

The Committee has not formulated any policy regarding qualifying compensation
paid to the Company's Executive Officers for deductibility under the limits of
Section 162(m) of the Internal Revenue Code of 1986, as amended, because the
Committee does not anticipate that any executive officers would receive
compensation in excess of such limits in the foreseeable future.

                         REPORT OF THE AUDIT COMMITTEE

     The Audit Committee oversees the Company's financial reporting process on
behalf of the Board of Directors. We meet with management periodically to
consider the adequacy of the Company's internal controls and the objectivity of
its financial reporting. We discuss these matters with the Company's independent
auditors and with appropriate Company financial personnel and internal auditors.
We regularly meet privately with both the independent auditors and the internal
auditors, each of whom has unrestricted access to the Committee, and recommend
to the Board the appointment of the independent auditors and review periodically
their performance and independence from Management. In addition, the Committee
reviews the Company's financing plans and reports recommendations to the full
Board for approval and to authorize action.

     The Directors who serve on the Committee are all "Independent" for purposes
of the New York Stock Exchange listing standards. That is, the Board of
Directors has determined that none of us has a relationship to the Company that
may interfere with our independence from the Company and its management.

     In 2000, the Board adopted a written charter setting out the audit related
functions the Committee is to perform. You can find a copy of that charter
attached to this proxy statement as Appendix A.

     Management has primary responsibility of the Company's financial statements
and the overall reporting process, including the Company's system of internal
controls. The independent auditors audit the annual financial statements
prepared by Management, express an opinion as to whether those financial
statements fairly present the financial position, results of operations and cash
flows of the Company in conformity with generally accepted accounting principles
and discuss with us any issues they believe should be raised with us.

     This year, we reviewed the Company's audited financial statement and met
with both Management and Hausser + Taylor, LLP, the Company's independent
auditors, to discuss those financial statements. Management has represented to
us that the financial statements were prepared in accordance with generally
accepted accounting principles.

     We have received from and discussed with Hausser + Taylor, LLP, the written
disclosure and the letter required by Independence Standards Board Standard No.
1 (Independence Discussions with Audit Committees). These items related to that
firm's independence from the Company. We also discussed with Hausser + Taylor,
LLP, any matters required to be discussed by Statement on Auditing Standards No.
61 (Communication with Audit Committees).

     Based on these reviews and discussions, we recommended to the Board that
the Company's audited financial statements be included in the Company's Annual
Report on Form 10-K for the fiscal year ended December 31, 2001.

                              INDEPENDENT AUDITORS

APPOINTMENT OF HAUSSER + TAYLOR, LLP

     On November 9, 1999, at a meeting of the Board of Directors, Hausser +
Taylor, LLP, was approved as the Registrant's engaged certifying independent
accountant for the fiscal year ending December 31, 1999.

     Hausser + Taylor, LLP has a continuing relationship with American Express
Tax and Business Services Inc. ("TBS") from which it leases auditing staff who
are full time, permanent employees of TBS and through which its partners provide
non-audit services. As a result of this arrangement, Hausser + Taylor, LLP has
no full time employees and therefore, none of the audit services performed were
provided by permanent full-time employees of Hausser + Taylor, LLP. Hausser +
Taylor, LLP manages and supervises the audit and audit staff, and is exclusively
responsible for the opinion rendered in connection with its examination.

AUDIT FEES

     Audit services of Hausser + Taylor, LLP for the year ended December 31,
2001 included the audit of the financial statements of the Company included in
the Annual Report to Shareholders for 2001 and services related to quarterly
filings with the Securities and Exchange Commission. Fees for these services
totalled approximately $56,000 and $7,800, respectively, for the year ended
December 31, 2001. There are no existing direct or indirect understandings or
agreements that place a limit on future years' audit fees. The Audit Committee
does not consider the fees charged the Company to be incompatible with
maintaining the independence of Hausser + Taylor, LLP.

ALL OTHER FEES

     Hausser + Taylor, LLP also provided consultation and assistance on
accounting related matters for the year ended December 31, 2001. Fees for these
services totalled approximately $2,700 for the year ended December 31, 2001.
There are no existing direct or indirect understandings or agreements that place
a limit on future years' fees for consultation and assistance on accounting
related matters. The Audit Committee does not consider the fees charged the
Company to be incompatible with maintaining the independence of Hausser +
Taylor, LLP.

     PROPOSAL 2 -- RATIFICATION OF THE APPOINTMENT OF INDEPENDENT AUDITORS

     The firm of Hausser + Taylor, LLP served as independent auditors of the
Company for the year ended December 31, 2001 and has been selected by the
Company to serve as its independent auditors for the year ending December 31,
2002. Hausser + Taylor, LLP became the Company's independent auditors on
November 9, 1999, succeeding McGladrey & Pullen, LLP which served as the
Company's independent auditors of the Company since January 10, 1996. Although
the submission of this matter for approval by the stockholders is not legally
required, the Board believes that such submission follows sound business
practice
                                        11


and is in the best interests of the stockholders. If the appointment is not
ratified by the holders of a majority of the shares present in person or by
proxy at the Annual Meeting, the Directors will consider the selection of
another accounting firm. If such a selection were made, it may not become
effective until 2003 because of the difficulty and expense of making such a
substitution. A representative of Hausser + Taylor, LLP, is expected to attend
the Annual Meeting and will be available to respond to appropriate questions.
That representative will have the opportunity to make a statement if they desire
to do so.

     THE BOARD OF DIRECTORS OF THE COMPANY UNANIMOUSLY RECOMMENDS THAT YOU VOTE
"FOR" THE RATIFICATION OF HAUSSER + TAYLOR, LLP. The affirmative vote of the
holders of a majority of shares of common stock present in person or by proxy at
the Annual Meeting will be required for such ratification.

                                 OTHER MATTERS

     The Company is not aware of any matters to be presented for action at the
Annual Meeting other than the matters set forth above. If any other matters do
properly come before the meeting or any adjournment thereof, it is intended that
the persons named in the proxy will vote in accordance with their judgment on
such matters.

                STOCKHOLDERS' PROPOSALS FOR NEXT ANNUAL MEETING

     The Board of Directors requests that any shareholder proposals intended for
inclusion in the Company's proxy materials for the 2003 Annual Meeting be
submitted to James K. McHugh, Chief Financial Officer, Treasurer and Corporate
Secretary of the Company, in writing no later than January 10, 2003. Unless the
Company has been given written notice by February 18, 2003 of a shareholder
proposal to be presented at the 2003 Annual Meeting other than by means of
inclusion in the Company's proxy materials for the meeting, persons named in the
proxies solicited by the Board of Directors for the meeting may use their
discretionary voting authority to vote against the proposal.

                                          By the Order of the Board of Directors

                                          /s/ James K. McHugh
                                          JAMES K. MCHUGH
                                          Chief Financial Officer, Secretary and

and employees and the independent auditors that:

     - The Committee members expect the Company's management and employees and
       the independent auditors to cooperate with the Committee and to provide
       the Committee with prompt and accurate information so that the committee

       Incorporation and other applicable indemnification provisions in any
       agreement between the Company and any member of the Committee.

     - While the Committee has the responsibilities and powers set forth in this
       Charter, it is not the duty or responsibility of the Committee to plan or
       conduct audits or to determine that the Company's financial statements
       are true and fair or in accordance with generally accepted accounting
       principles as applied in the United States. These are the responsibility
       of the independent auditors and the Board, respectively.

     - While the Committee is encouraged to act as a link between the
       independent auditors, management and the Board, including as a conduit
       for the independent auditors and management to raise matters of
       importance, which may include items of dispute, and to initiate or
       request investigations of matters that it considers necessary or
       appropriate to carry out its responsibilities under this Charter, it is
       not the duty nor the obligation of the Committee to conduct
       investigations, to resolve disputes or disagreements, if any, between
       management and the independent auditors or to assure compliance with
       applicable laws and/or regulations or the Company's Code of Conduct.
