Annual Meeting is required for the election of Directors. Therefore, the five
nominees who receive the most votes will be elected. The affirmative vote of a
majority of the votes cast at the Annual Meeting is required for the
ratification of Ernst & Young LLP as the Company's independent auditors; on all
other matters which may come before the Annual Meeting, the affirmative vote of
a majority of the votes cast at the Annual Meeting is required. For purposes of
determining whether proposals have received a majority vote, abstentions will
not be included in the vote totals and, in instances where brokers are
prohibited from exercising discretionary authority for beneficial owners who
have not returned a proxy ("broker non-votes"), those votes will not be
included in the vote totals. Therefore, abstentions and broker non-votes will
be counted in the determination of a quorum and will have no effect on the vote

                            EXECUTIVE COMPENSATION

     The following report and the performance graph on page 11 do not
constitute soliciting materials and are not considered filed or incorporated by
reference into any other of the Company's filings under the Securities Act of
1933, as amended, or the Securities Exchange Act of 1934, as amended, unless
the Company states otherwise.


REPORT OF THE COMPENSATION COMMITTEE

     COMPENSATION POLICIES. The principal goal of the Company's compensation
program as administered by the Board of Directors is to help the Company
attract, motivate and retain the executive talent required to develop and
achieve the Company's strategic and operating goals with a view to maximizing
shareholder value. The key elements of this program and the objectives of each
element are as follows:

     BASE SALARY. Base salaries paid to the Company's executive officers are
intended to be competitive with those paid to executives holding comparable
positions in the marketplace. Individual performance and the Company's
performance are considered when setting salaries within the range for each
position. Annual reviews are held and adjustments are made based on attainment
of individual goals in a manner consistent with operating and financial
performance.

     BONUSES. Annual cash bonuses are intended to motivate performance by
creating the potential to earn incentive awards that are contingent upon
personal and business performance. The Company sets goals of revenue and
profitability for each segment.

     LONG TERM INCENTIVES. The Company provides its executive officers with
long-term incentive compensation through grants of stock options under the
Company's stock option plans. The grant of stock options aligns the executive's
interest with those of the Company's shareholders by providing the


                                       6


executive with an opportunity to purchase and maintain an equity interest in
the Company's stock and to share in the appreciation of its value. In fiscal
2003 options to purchase 260,000 shares of Common Stock were granted to the
Company's executive officers.


     CEO'S COMPENSATION. Michael A. McManus is entitled to receive an annual
base salary of $275,000 and is entitled to receive a minimum bonus of $250,000
and a maximum bonus of $350,000 per year based on the Company's pretax
operating earnings. Mr. McManus also received options to purchase 125,000
shares of Common Stock at a purchase price of $4.66 per share. The factors
involved in determining the CEO's compensation are the Company's revenues and
profits, his lengthy experience and business acumen, his responsibilities, and
the efforts exerted by him in performance of his duties. The options to
purchase the 125,000 shares vest as follows: 50% of the options vested
immediately and the balance vest on November 1, 2004. The options expire on the
tenth anniversary of the date of grant.

shareholder owning more than 10% of the outstanding Common Stock may not exceed
five years and its exercise price may not be less than 110% of the fair market

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE


     Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's officers, Directors and persons who own more than ten percent of
a registered class of the Company's equity securities ("Reporting Persons") to
file reports of ownership and changes in ownership on Forms 3, 4 and 5 with the
Securities and Exchange Commission (the "SEC") and the National Association of
Securities Dealers, Inc. (the "NASD"). These Reporting Persons are required by
SEC regulation to furnish the Company with copies of all Forms 3, 4 and 5 they
file with the SEC and NASD. Based solely on the Company's review of the copies
of the forms it has received, the Company believes that all Reporting Persons
complied on a timely basis with all filing requirements applicable to them with
respect to  transactions during fiscal year 2003.

Company's 2003 fiscal year.


ALL OTHER FEES:

     Ernst & Young LLP has billed the Company $29,800 in the aggregate for

accounting issues and changes in professional statements and (iv) income tax
returns for Labcaire, the Company's UK subsidiary.

certain officers and regular employees of the Company may solicit proxies by
telephone, telegraph or personal interview without additional remuneration

proxy rules, proxies solicited by the Board of Directors for the 2004 Annual
Meeting may be voted at the discretion of the persons named in such proxies (or
their substitutes) with respect to any shareholder proposal not included in the
Company's proxy statement if the Company does not receive notice of such
proposal on or before November 4, 2004, unless the 2004 Annual Meting is not
