SECOND SUPPLEMENT TO PROXY STATEMENT ------------------------------------ FOR THE 2002 ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON NOVEMBER 18, 2002 The Proxy Statement, dated October 9, 2002, as supplemented by the Supplement to Proxy Statement, dated November 1, 2002, each previously furnished to stockholders of Scientific Industries, Inc. (the "Company") for the solicitation by the Board of Directors of proxies to be voted at the Annual Meeting of Stockholders of the Company to be held at the Princeton Club, 15 West 43rd Street, New York, New York 10036 on Monday, November 18, 2002 at 10:30 A.M. (New York Time) is hereby supplemented further as follows: Voting Information "Broker non-votes" with respect to a particular matter are shares held in street name that are not voted on the matter because either no instructions are given by the beneficial owner as to how to vote the shares or the broker is not permitted under applicable rules because of the subject matter of the proposal to vote such shares, but whose shares are present on at least one matter. Such shares will be deemed present in determining a quorum but, in the view of the Company, they should not be counted as voting on each proposal at this Meeting; accordingly, they will not have any effect on any of the proposals presented to the stockholders at this Meeting. As stated in the Proxy Statement as supplemented, the vote required to approve the proposals to approve the 2002 Stock Option Plan, the ratification of the independent auditors and the Kleiman Stockholder Proposal, is, in each case, the affirmative vote of the holders of a majority of the votes cast. There is uncertainty regarding the manner in which we intend to calculate such votes under the Company's Bylaws and Delaware law. Proxy Cards You should have received the WHITE proxy card (the "Original Proxy Card") which accompanied the Proxy Statement dated October 9, 2002 and a second WHITE proxy card (the "Second Proxy Card") which accompanied the Supplement to Proxy Statement dated November 1, 2002. Another copy of the Second Proxy Card is enclosed herewith. The Original Proxy Card did not include any reference to the Kleiman Stockholder Proposal. Please note that consistent with Delaware law: If you have not returned the Original Proxy Card, please discard it. If you have previously returned the Original Proxy Card and have not returned the Second Proxy Card, you will have given the Company's Board of Directors' designated proxy holders discretion to vote your shares against the Kleiman Stockholder Proposal and that is all you need to do if you support your Board's recommendation. If you wish to specify the manner in which your shares are to be voted on any of the proposals (including the Kleiman Stockholder Proposal), you should mark, sign, date and return either the Second Proxy Card or the accompanying WHITE proxy card. If you have not returned either the Original Proxy Card or the Second Proxy Card, we encourage you to sign, date and return the enclosed proxy card and return it in the enclosed self-addressed postage pre-paid envelope.
