Dear Fellow Scientific Industries Stockholder:

     I am the owner of 139,581 shares of common stock representing more than 14%
of the outstanding shares of Scientific Industries, Inc. (the "Company"). As a
significant stakeholder in the Company, I am concerned about its current
financial performance and the Company's future prospects. AS A RESULT, I AM
RUNNING FOR DIRECTOR IN OPPOSITION TO ONE OF THE COMPANY'S PROPOSED DIRECTORS.

     You may have already received management's proxy materials for the Annual
Meeting of Scientific Industries, Inc. that is scheduled to be held on November
18, 2002. I BELIEVE CERTAIN INFORMATION IN THEIR MATERIAL IS FALSE AND
MISLEADING. I AM WRITING THIS LETTER TO URGE ALL STOCKHOLDERS TO REFRAIN FROM
RETURNING THE WHITE PROXY CARD SENT BY MANAGEMENT.

     I will soon be mailing my own proxy materials in opposition to management
along with a BLUE proxy card, which can be used to vote FOR my reelection to the
Board of Directors, FOR one of the Company's nominees, Mr. Joseph Cremonese, and
AGAINST the 2002 Stock Option Plan. When my proxy materials are cleared by the
Securities and Exchange Commission, you will receive a full explanation of why I
feel I should remain on the Board of Directors and why, I believe, the 2002
Stock Option Plan is not in the best interests of the Company's stockholders.
UNTIL THAT TIME, I IMPLORE YOU TO TAKE NO ACTION REGARDING THE ANNUAL MEETING
AND TO MAKE AN INFORMED DECISION AFTER RECEIVING MY PROXY MATERIALS AND THE BLUE
PROXY CARD.

                           SETTING MY RECORD STRAIGHT

     I have been a member of the Scientific Industries Board for 32 years and
have dedicated my entire career to helping the Company grow and striving to
responsibly increase value for all stockholders. MY GOAL HAS ALWAYS BEEN TO
STRATEGICALLY EXPAND THE COMPANY'S PRODUCT BASE WITH A LONG-TERM OUTLOOK TOWARDS
CREATING VALUE FOR ALL OF THE COMPANY'S STOCKHOLDERS.

     Unfortunately, I sense that current management does not have your interests
in mind and is instead using your Company as a means of satisfying their
self-serving financial ends. This is evident, I believe, in management's support
of the 2002 Stock Option Plan that would increase management's potential
financial gains while unacceptably diluting the value of your investment. IN ITS
PROXY STATEMENT, MANAGEMENT CLAIMS THAT THE BOARD OF DIRECTORS "UNANIMOUSLY"
RECOMMENDS A VOTE FOR THE 2002 OPTION PLAN BUT THAT SIMPLY IS NOT TRUE. IN MY
CAPACITY AS A BOARD MEMBER, I VOICED MY OPPOSITION TO AND ABSTAINED FROM VOTING
FOR THE PLAN AND YET MANAGEMENT IMPLIES THAT I SUPPORTED IT.


                 VOTE THE BLUE PROXY TO PROTECT YOUR INVESTMENT

     Like you, I am also an investor in Scientific Industries. As such, I
believe that we need a Board of Directors that can be trusted to take the
actions that are necessary to strengthen the Company and enhance the value of
our investment. Current management dismissed me from the Company and is now
trying to dismiss me from the Board because, I believe, they viewed me as an
impediment to their self-serving goals. HOWEVER, AS A PERSON WHO BELIEVES THAT
THE COMPANY IS NOW IN A POSITION TO TAKE STEPS TOWARDS STRATEGIC,
VALUE-ENHANCING GROWTH, AND WHO HAS A SIGNIFICANT FINANCIAL STAKE IN MAKING SURE
THE COMPANY ADHERES TO THE HIGHEST STANDARDS OF CORPORATE GOVERNANCE, I AM
ASKING FOR YOUR SUPPORT IN MY CAMPAIGN.

     You will soon be receiving my definitive proxy materials which will explain
in detail my position regarding the recent actions of management. IN THE
INTERIM, I AGAIN URGE YOU NOT TO RETURN ANY WHITE PROXY CARD SUPPLIED BY
MANAGEMENT AND TO VOTE THE BLUE PROXY CARD WHEN YOU RECEIVE IT. If you have any
questions, please call Dan Sullivan or Bob Sandhu of MacKenzie Partners, Inc. at
(212) 929-5500 or (800) 322-2885.

Very Truly Yours,


Lowell A. Kleiman
