As of that date, Meridian had 14,585,081 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 the Company's independent public accountants for fiscal year 2000. 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. And 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 9. 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 five director candidates receiving the most votes will be elected to fill the seats on the Board. Approval of the other proposal requires the favorable vote of a majority of the votes cast. Only votes for or against a proposal count. Abstentions and broker non-votes count for quorum purposes but not for voting purposes. Broker non-votes occur when a broker returns a proxy card but does not have authority to vote on a particular proposal. Other Matters Any other matters considered at the meeting, including adjournment, will require the affirmative vote of a majority of shares voting. Voting by Proxy All proxies properly signed will, unless a different choice is indicated, be voted "FOR" the election of all nominees for Directors proposed by the Board of Directors and "FOR" ratification of the selection of independent public accountants. 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. 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 the Company on your behalf.

The Board is nominating for reelection all of the following current directors: James A. Buzard, John A. Kraeutler, Gary P. Kreider, William J. Motto 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 their votes. Three of our five 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 given below.

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 and then 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 reported immediately prior to the date of grant. 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 the Company's internal accounting operations. It also recommends the employment of independent accountants and reviews the relationship between the Company and its outside accountants. Committee members: Messrs. Buzard, Kreider and Ready (Chairman). Meetings last year: 4 Actions in writing last year: 0 The Compensation Committee is responsible for establishing compensation for management and administering the Company's stock option plans. Committee members: Messrs. Buzard (Chairman), Kreider and Ready. Meetings last year: 3 Actions in writing last year: 4 COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION Report of the Compensation Committee The Compensation Committee is charged with establishing compensation for executive officers through the establishment of salaries and bonus plans as well as making bonus awards and awarding stock options. At a meeting held September 17, 1998, the Committee set salaries for executive officers for fiscal 1999. In establishing these salaries, the Committee reviewed background information showing the fiscal 1998 compensation for Meridian's executives, along with comparisons of certain peer companies as well as comparisons with the instruments and biomedical equipment and supply group. This process allowed increases to be tied more to the executives' responsibilities, development and contributions to Meridian's operations. The salary of the Chief Executive Officer, Mr. Motto, was determined in the same manner. At a meeting held November 17, 1999, the Committee reviewed the bonus plan adopted for fiscal 1999 and confirmed the award of bonuses pursuant to the plan since the earnings targets set in the plan were achieved. The Committee also awarded special bonuses of $25,000 each to Messrs. Blain, Eberly, Kraeutler and Motto reflecting their extraordinary efforts in the acquisition of Gull Laboratories. The Committee also established a bonus plan for fiscal 2000. This plan calls for the award of bonuses if designated net earnings levels are met. The amount of each bonus is determined by multiplying base compensation by percentages keyed to earnings levels, and then applying a personal achievement multiplier to that result. The methodology of this plan is the same as employed in the past several years. At other meetings during fiscal 1999, the Committee awarded options from the Company's previously approved Stock Option Plan reflecting its view of the importance of particular executives to the Company's future performance.
