GENERAL INFORMATION

Who may vote

Shareholders of Meridian, as recorded in our stock register on December 3, 2001,
may vote at the meeting. As of that date, Meridian had 14,599,170 shares of
Common Stock outstanding.

How to vote

You may vote in person at the meeting or by proxy. We recommend you vote by
proxy even if you plan to attend the meeting. You can always change your vote at
the meeting.

How proxies work

Meridian's Board of Directors is asking for your proxy. Giving us your proxy
means you authorize us to vote your shares at the meeting in the manner you
direct. You may vote for all, some or none of our director candidates. You may
also vote for or against the other proposals or abstain from voting.

If you sign and return the enclosed proxy card but do not specify how to vote,
we will vote your shares in favor of our director candidates and in favor of the
ratification of Arthur Andersen LLP as Meridian's independent public accountants
for fiscal year 2002.

If any other matters come before the meeting or any adjournment, each proxy will
be voted in the discretion of the individuals named as proxies on the card.

You may receive more than one proxy or voting card depending on how you hold
your shares. Shares registered in your name are covered by one card. If you hold
shares through someone else, such as a stockbroker, you may get material from
them asking how you want to vote.

Revoking a proxy

You may revoke your proxy before it is voted by submitting a new proxy with a
later date, by voting in person at the meeting, or by notifying Meridian's
Secretary in writing at the address under "Questions?" on page 14.

Quorum

In order to carry on the business of the meeting, we must have a quorum. This
means at least a majority of the outstanding shares eligible to vote must be
represented at the meeting, either by proxy or in person.

Votes needed

The six director candidates receiving the most votes will be elected to fill the
seats on the Board.

Ratification of appointment of accountants requires the favorable vote of a
majority of the votes cast. Only votes for or against these proposals count.

Other Matters

Any other matters considered at the meeting, including adjournment, will require
the affirmative vote of a majority of the votes cast.

ELECTION OF DIRECTORS
(Item 1 on the Proxy Card)

The Board has nominated the director candidates named below.

The Board of Directors oversees the management of Meridian on your behalf. The
Board reviews Meridian's long-term strategic plans and exercises direct
decision-making authority in key areas, such as choosing the Chief Executive
Officer, setting the scope of his authority to manage Meridian's business day to
day and evaluating management's performance.

The Board is nominating for election all of the following current directors:
James A. Buzard, John A. Kraeutler, Gary P. Kreider, William J. Motto, David C.
Phillips and Robert J. Ready.

Proxies solicited by the Board will be voted for the election of these nominees.
All directors elected at the Annual Meeting will be elected to hold office until
the next annual meeting. In voting to elect directors, shareholders are entitled
to cumulate their votes and to give one candidate a number of votes equal to the
number of directors to be elected multiplied by the number of shares held by the
shareholder, or to distribute their votes on the same principle among as many
candidates as the shareholder sees fit. In order to invoke cumulative voting,
notice of cumulative voting must be given in writing by a shareholder to the
President, a Vice President or the Secretary of Meridian not less than 48 hours
prior to the Annual Meeting. The proxies solicited include discretionary
authority to cumulate votes.

Four of our six nominees are not Meridian employees. Only non-employee directors
serve on Meridian's Audit and Compensation committees. All Meridian directors
are elected for one-year terms. Personal information on each of our nominees is

DIRECTOR COMPENSATION

Non-employee directors of Meridian receive $12,000 per year for serving as a
director and as members of committees of the Board. They also receive $1,000 for
each director or committee meeting attended, except if a committee meeting
occurs on the same day as a directors' meeting the committee meeting fee is
$800. They receive $500 for each director or committee meeting held by
telephone. Committee chairmen receive an additional $500 for each committee
meeting held. Each non-employee director is also granted a non-qualified option
to purchase 2,317 shares of Common Stock at the time of election or re-election
to the Board of Directors, with the exercise price being the closing sale price
on Nasdaq reported immediately prior to the date of grant. If a change in
control occurs, non-employee directors will receive lump-sum payments equal to
ten times their annual compensation received in the prior fiscal year. Directors
who are employees of Meridian are not separately compensated for serving as
directors.

BOARD COMMITTEES

The Board appoints committees to help carry out its duties. In particular, Board
committees work on key issues in greater detail than would be possible at full
Board meetings. Each committee reviews the results of its meetings with the full
Board. The Board of Directors does not have a nominating committee or executive
committee.

The Audit Committee is responsible for reviewing Meridian's internal accounting
operations. It also recommends the employment of independent accountants and
reviews the relationship between Meridian and its outside accountants.

REPORT OF THE AUDIT COMMITEE

Meridian's Audit Committee is composed of Messrs. Ready (Chairman), Buzard and
Kreider.  All of the members of the Committee meet the NASD standards for
independence and financial literacy.

In April 2000, the Board adopted the Audit Committee Charter, which was attached
to last year's Proxy Statement as Appendix I. The Charter outlines the
activities and responsibilities of the Committee.

In August 2001, the Committee met with representatives of Arthur Andersen and
Meridian's internal accountants and reviewed with them the proposed 2001 Audit
Plan, areas warranting particular concentration on the audit and the effects of
new accounting pronouncements. The Committee also reviewed business analysis and
initial risk assessments and the implementation of new accounting rules on
business combinations, goodwill and intangible assets presented by Arthur
Andersen.

At its meeting in November 2001, the Committee reviewed with management, Arthur
Andersen and Meridian's accounting officers the results of the audit for fiscal
2001, including the audited financial statements. The Committee reviewed the
requirements


                                      -7-

of its Charter previously adopted and the reports that were required to be
disclosed to the Committee. The Committee discussed with Arthur Andersen the
matters required to be discussed by Statement on Auditing Standards No. 61. The
Arthur Andersen representatives reviewed with the Committee written disclosures
required by the Independence Standards Board Standard No. 1 regarding
independence of the public accountants and presented a letter regarding that
matter to the Committee.

Relying upon the discussions and reviews described above, the Committee
recommended to the Board of Directors that the audited financial statements of
Meridian be included in its Annual Report on Form 10-K for the year ended
September 30, 2001 for filing with the Securities and Exchange Commission.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

Report of the Compensation Committee

Meridian's Compensation Committee is composed of Messrs. Buzard (Chairman),
Kreider, Phillips and Ready. The Compensation Committee is responsible for
establishing compensation for executive officers, establishing salary levels and
bonus plans, making bonus awards and otherwise dealing in all matters concerning
compensation of the executive officers and awarding stock options for all
employees.

At its meeting on November 16, 2000, the Committee set the salaries for the
executive officers for fiscal 2001 as shown in the Summary Compensation Table.
The Committee had available to it in establishing executive salaries the
recommendations of management with respect to overall staff level compensation
for the coming fiscal year for Meridian. The Committee took into account these
considerations plus the financial performance of Meridian during fiscal 2000 in
establishing salary levels. It determined the compensation for the Chief
Executive Officer in the same manner it did for its other executive officers.
The Committee also considered a fiscal 2001 bonus award program based on
targeted earnings levels. The Committee met without Meridian's management in
making its decisions. At its meeting on November 16, 2000 and at other meetings
throughout the year, the Committee also awarded stock options pursuant to
Meridian's Stock Option Plan to various employees including the stock options to
executive officers listed elsewhere in this Proxy Statement.

At its meeting in September 2001, the Committee awarded incentive stock options
to certain employees and executive officers, which are tied to net earnings and
stock price targets. One series of options will vest immediately if Meridian's
net earnings for fiscal 2002 are at least $6,821,000. The other series will vest
if the stock price reaches designated price levels for 30 consecutive days
during fiscal 2002 plus the first 30 days of fiscal 2003 with the vesting
schedule being one-third at $12, one-third at $13 and one-third at $14. If these
targets are not reached, the options will not vest until nine years after the
date of grant. They also vest if Meridian or substantially all of its assets are
sold in fiscal 2002.

At its meeting on November 14, 2001, the Committee maintained salary levels for
Messrs. Motto, Kraeutler, Eberly and Interno for fiscal 2002 at fiscal 2001
levels, granted increases to operating officers and established a fiscal 2002
bonus award based on targeted net earnings levels from $6,475,000 to $7,500,000.

Respectfully submitted,
