Dear Fellow Scientific Industries Stockholder:

     As you may know, I am the former President, Chairman of the Board and Chief
Executive Officer of Scientific Industries, Inc. (the "Company"). I remain one
of the Company's largest stockholders as the owner of 139,581 shares,
representing more than 14% of the Company's outstanding common stock and am
still a member of the Board of Directors. However, the Company has decided not
to re-nominate me to the Board, so I am running independently. My decision to
run for the Board was made after a careful analysis of the Board's composition
and my conclusion that the Board lacks a shareholder voice necessary for the
future of the Company. I am running because I firmly believe that my continuing
presence on the Board is critical to the growth of the Company and necessary to
protect both your investment and mine. Therefore, I am soliciting BLUE proxies
to be used at the 2002 Scientific Industries Annual Meeting scheduled to be held
on November 18, 2002.

     During the last six years of my employment with the Company, I grew
increasingly critical of my fellow Board members and, I am convinced that this
criticism led to my ultimate dismissal from the Company. Now, as a concerned
stockholder and someone who believes that Scientific Industries is currently
poised for strategic growth, I am contesting the election of one of management's
nominees, Roger Knowles.

     Please take a moment to sign, date and return the enclosed BLUE proxy card
in order to vote FOR my reelection to the Board of Directors FOR the 2002 Stock
Option Plan, FOR my stockholder proposal to require stockholder approval of
option grants to non-employee directors and to otherwise limit the number of
shares that may be issued to them. Send a clear message to management that you
are concerned about the value of your investment- vote your BLUE proxy card
today!

        EXPERIENCED LEADERSHIP IS NEEDED AT THIS CRITICAL MOMENT FOR THE
                             GROWTH OF OUR COMPANY

     Prior to being summarily fired by the Company on August 29, 2002, I had
proposed to the Board a strategic business plan designed to establish a
foundation for the growth of the Company. Essentially, I presented a plan
whereby Scientific Industries would continue to expand its product base taking
advantage of our established name recognition with a significant marketing
program so that, within a few years' time we would no longer be operating as a
one-product company. Although the Board initially rejected my plan, it now
appears that they are prepared to act on certain parts of my proposal, including
my proposal pertaining to the development of new products. However, it also



appears, and I am very concerned, that the Board is not prepared to allocate the
necessary financial resources for research and development, as well as for
marketing, in order to achieve a meaningful increase in sales volume within the
next few years. It was this near term increase in sales volume which was at the
core of my plan.



     After years of responsible leadership by me and the capable management team
I hired, I was proud that we were able to achieve financial stability for the
Company. I believe that Scientific Industries is no longer undercapitalized and
that the capital that was generated during my tenure should be dedicated to the
growth of our Company. However, as indicated above, I am concerned that the
current Board may not be prepared to allocate sufficient capital towards
strengthening our Company.


                MY GOAL IS THE SAME AS YOURS - STOCKHOLDER VALUE

     As one of the largest stockholders of Scientific Industries, I have a
significant financial interest in the performance of the Company. By reelecting
me to the Board of Directors, you will have a Director whose interests will be
aligned with yours as a stockholder. As a director who has an in-depth
understanding of both the Company and the industry in which it operates, I will
provide a voice for all stockholders and will vigorously oppose any plan that
could be contrary to our goals as investors.



               THE 2002 STOCK OPTION PLAN - WE MADE CHANGE HAPPEN!

     When the Company mailed its proxy material to you on October 17, 2002, it
included a provision for stockholders to approve a Stock Option Plan which
contained no restrictions on the number of options which could be granted to
non-employee directors. When this Stock Option Plan was originally discussed
with the Board on September 26, 2002, I strenuously objected to the fact that
there was no such restriction. Although I had previously voted in favor of prior
grants to non-employee directors, my opposition now is grounded in my belief
that the non-employee members of the Board had already benefited from too many
option grants, to the detriment of the Company. In fact, since January 1, 1992,
the Company has granted a total of 385,000 options, of which 176,000, or 46%,
were granted to non-employee Directors.

     Subsequent to the Company mailing its proxy material to stockholders, I
notified the Company of my intention to seek election as a director, and I also
mailed a letter to certain stockholders informing them of my intent and bringing
to their attention the reasons I thought the Stock Option Plan was defective.

     Thereafter on October 28, 2002, and in direct response to my actions, the
Company modified the Stock Option Plan to impose restrictions on the grant of
options to current non-employee directors. Needless to say, I am pleased to see
my seeking to remain on the Board has already had a significant positive effect
on the Board's actions.

                                        2


     In my opinion, stock options can provide a useful and necessary means of
employee remuneration. Since the Company's Stock Option Plan as modified moves a
long way towards complying with my request, I now feel comfortable supporting
the Plan

                             MANAGEMENT KNOWS BEST?

     Acknowledging that management now has in place a Stock Option Plan that I
find acceptable, I have proposed that the Board adopt a policy requiring that
all grants to non-employee directors be subject to stockholder approval and that
the number of options eligible for non-employee directors be limited to 20% of
any plan. I believe this policy will allow the Company to attract and retain
talented employees and independent directors as well. However, in its proxy
materials, management argues against any restrictions on grants to future
non-employee directors and states that my proposal to require stockholder
approval is "unreasonable, possibly motivated by vindictiveness." I take sharp
exception to that characterization and encourage all stockholders to join with
me in adopting this policy statement.

             I NEED YOUR SUPPORT - PLEASE VOTE THE BLUE PROXY TODAY!

      I have spent thirty-seven years of my career at Scientific Industries and,
even though I accepted a salary that was well below the standard for comparable
positions within our peer group of companies, I believed and continue to believe
that Scientific Industries has a promising future. My belief has led me to
launch this campaign, paid for from my own funds, in the hope that you will
agree that the Company and its stockholders need and deserve my continued
presence as a director to protect our investment.

     Please take a moment now to sign date and return the enclosed BLUE proxy
card. If you have any questions or require assistance in voting your shares,
please call Dan Sullivan or Bob Sandhu of MacKenzie Partners, Inc. at (800)
322-2885 (toll free) or (212) 929-5500 (call collect).

                            -------------------------

                    PLEASE MAIL THE ENCLOSED BLUE PROXY CARD

I am the former President and Chief Executive Officer as well as a current
director and one of the largest stockholders of Scientific Industries, Inc., a
Delaware corporation ("SCND" or the "Company"). I am writing to you in
connection with the election of two directors to SCND's Board of Directors at
the annual meeting of stockholders scheduled to be held at the Princeton Club,
located at 15 West 43rd Street, New York, New York on November 18, 2002, at
10:30 A.M., including any adjournments or postponements thereof and any meeting
which may be called in lieu thereof (the "Annual Meeting"). I am seeking to be
re-elected as a director in opposition to one SCND's incumbent director
nominees, Roger Knowles, whose term expires at the Annual Meeting. There can be
no assurance that my election will maximize or otherwise enhance stockholder
value or improve corporate governance.

This proxy statement (the "Proxy Statement") and the enclosed BLUE proxy card
are being furnished to stockholders of SCND by me in connection with the
solicitation of proxies from SCND's stockholders to be used at the Annual
Meeting to elect me to the Board of Directors of SCND (the "SCND Board"). I have
been a director of SCND since 1970 and served as President from 1974 until
August 29, 2002. This Proxy Statement and the BLUE proxy card are first being
furnished to SCND's stockholders on or about November __, 2002.

SCND has set the record date for determining stockholders entitled to notice of
and to vote at the Annual Meeting as of September 27, 2002 (the "Record Date").
The principal executive offices of SCND are located at 70 Orville Drive,
Bohemia, New York 11716. Stockholders of record at the close of business on the
Record Date will be entitled to vote at the Annual Meeting. According to SCND,
as of the Record Date, there were 953,541 shares of common stock, $0.05 par
value per share (the "Shares"), outstanding and entitled to vote at the Annual
Meeting. I am the beneficial owner of 139,581 Shares which represents
approximately 14.7% of the Shares outstanding (based on information publicly
disclosed by SCND). I intend to vote such Shares for my election as a director.

THIS SOLICITATION IS BEING MADE BY ME AND NOT ON BEHALF OF THE BOARD OF
DIRECTORS OR MANAGEMENT OF SCND. I AM NOT AWARE OF ANY OTHER MATTERS TO BE
BROUGHT BEFORE THE ANNUAL MEETING OTHER THAN THE PROPOSAL TO APPROVE THE 2002
STOCK OPTION PLAN OF THE COMPANY, RATIFICATION OF THE APPOINTMENT OF THE
COMPANY'S AUDITORS AND TO ADOPT THE STOCKHOLDER PROPOSAL DESCRIBED IN THESE
PROXY MATERIALS TO PLACE RESTRICTIONS ON THE GRANT OF STOCK OPTIONS TO
NON-EMPLOYEE DIRECTORS IN THE EVENT THE PROPOSAL TO ADOPT THE 2002 STOCK OPTION
PLAN IS APPROVED. SHOULD OTHER MATTERS, WHICH I AM NOT AWARE OF A REASONABLE
TIME BEFORE THIS SOLICITATION, BE BROUGHT BEFORE THE ANNUAL MEETING, THE PERSONS
NAMED AS PROXIES IN THE ENCLOSED BLUE PROXY CARD WILL VOTE ON SUCH MATTERS IN
THEIR DISCRETION.

I URGE YOU TO SIGN, DATE AND RETURN THE BLUE PROXY CARD IN FAVOR OF MY ELECTION
AS DIRECTOR IN LIEU OF MANAGEMENT'S NOMINEE, ROGER KNOWLES, ALL AS MORE FULLY
DESCRIBED IN THIS PROXY STATEMENT.

IF YOU HAVE ALREADY SENT A PROXY CARD FURNISHED BY SCND MANAGEMENT TO THE SCND
BOARD, YOU MAY REVOKE THAT PROXY AND VOTE AGAINST THE ELECTION OF SCND'S
NOMINEES BY SIGNING, DATING AND RETURNING THE ENCLOSED BLUE PROXY CARD. THE
LATEST DATED PROXY IS THE ONLY ONE THAT COUNTS. ANY PROXY MAY BE REVOKED AT ANY
TIME PRIOR TO THE ANNUAL MEETING BY DELIVERING A WRITTEN NOTICE OF REVOCATION OR



A LATER DATED PROXY FOR THE ANNUAL MEETING TO ME, C/O MACKENZIE PARTNERS, INC.
WHICH IS ASSISTING IN THIS SOLICITATION, OR TO THE SECRETARY OF SCND, OR BY
VOTING IN PERSON AT THE ANNUAL MEETING.

                                    IMPORTANT

YOUR VOTE IS IMPORTANT, NO MATTER HOW MANY OR HOW FEW SHARES YOU OWN. I URGE YOU
TO SIGN, DATE AND RETURN THE ENCLOSED BLUE PROXY CARD TODAY TO VOTE FOR MY
RE-ELECTION, FOR RATIFICATION OF THE APPOINTMENT OF THE COMPANY'S AUDITORS, FOR
THE STOCK OPTION PLAN AND FOR THE STOCKHOLDER PROPOSAL TO PLACE RESTRICTIONS ON
THE GRANT OF STOCK OPTIONS TO NON-EMPLOYEE DIRECTORS IN THE EVENT THE PROPOSAL
TO ADOPT THE 2002 STOCK OPTION PLAN IS APPROVED.

I am committed, subject to my fiduciary duty to SCND's stockholders, to
maximizing the long-term value of your Shares. A vote FOR me will enable you -
as the owners of SCND - to send a message to the SCND Board that you are
committed to maximizing the value of your Shares.

     o    If your Shares are registered in your own name, please sign and date
          the enclosed BLUE proxy card and return it to me, c/o MacKenzie

PROPOSAL I - ELECTION OF DIRECTORS

REASONS FOR THE SOLICITATION

I am asking you to re-elect me in order to:

     o    Remove Roger Knowles, an incumbent director up for re-election; and

     o    elect a nominee that supports actions that I believe would give
          stockholders the greatest opportunity to maximize the long-term value
          of their Shares.

I believe that my re-election represents the best means for SCND's stockholders
to maximize the value of their Shares. By electing me, I believe the Board will
have a director who has an in-depth understanding of both the Company and the
industry in which it operates. I will encourage the Company to allocate the
resources necessary for research and development and marketing that I believe is
important for the Company to achieve a meaningful increase in sales within the
next few years. As one of the largest stockholders of SCND, I have a vested
interest in the maximization of the value of the Shares. There can be no
assurance that my election will maximize or otherwise enhance stockholder value.

MY BACKGROUND

The following information sets forth me, as nominee for director, my name,
business address, present principal occupation, and employment and material
occupations, positions, offices, or employments for the past five years. 7.

I, Lowell A. Kleiman (age 61), have been a Director of SCND since 1970 and had
been employed by the Company for over thirty seven years, and served as
President from September 1974 until August 29, 2002, when my employment with the
Company was terminated. I am a citizen of the United States. My business address
is c/o Warshaw Burstein Cohen Schlesinger & Kuh, LLP, 555 Fifth Avenue, New
York, New York 10017.

There are no arrangements or understandings between me and any other person or
persons pursuant to which the nomination described herein is to be made, other
than the consent by me to be named in this Proxy Statement and to serve as a
director of SCND if elected as such at the Annual Meeting. I have not been
convicted in any criminal proceedings (excluding traffic violations or similar
misdemeanors) over the past ten years. I am not a party adverse to SCND or any
of its subsidiaries or have a material interest adverse to SCND or any of its
subsidiaries in any material pending legal proceedings.

I expect that I will be able to stand for election, but, in the event that I am
unable to serve or for good cause will not serve, the Shares represented by the
enclosed BLUE proxy card will be voted for a substitute nominee. In addition, I
reserve the right to nominate a substitute or additional person if SCND makes or
announces any changes to its Bylaws or takes or announces any other action that
has, or if consummated would have, the effect of disqualifying me. In any such
case, the Shares represented by the enclosed BLUE proxy card will be voted for
such substitute nominee.

The SCND Board is divided into three classes serving staggered three-year terms.
Two directors are to be elected at the Annual Meeting to hold office until 2005
and until their successors are duly elected and qualify. The Board has nominated
Roger Knowles and Joseph Cremonese to serve as Management's nominees.

In accordance with applicable proxy regulations, I intend to use my proxies to
vote for one of the two individuals nominated by the Board to serve as a
director. Further, I intend to use my proxy to vote for me and not Roger
Knowles.

Stockholders who use the BLUE Proxy Card will be able to vote for me and one of
the Company's nominees. The Company nominee for whom I do not intend to vote is
Mr. Roger Knowles. Stockholders cannot vote for me and also vote for one of the
Company's nominees using the Company's proxy card. Any stockholder who wishes to
vote for me and Mr. Knowles will be required to vote by ballot at the 2002
Annual Meeting. Stockholders should refer to the Company's proxy statement for
information concerning the Company's nominees. There is no assurance that any of
the Company's nominees will serve as directors if I am re-elected to the
Company's Board.


YOU ARE URGED TO VOTE FOR MY RE-ELECTION ON THE ENCLOSED BLUE PROXY CARD.
PROPOSAL 2 - ADOPTION OF THE 2002 STOCK OPTION PLAN

The Company has proposed the adoption of the 2002 Stock Option Plan ("Plan")
which would permit the Company to issue options to purchase up to 261,000 shares
of the Company's Common Stock. Inasmuch as the Plan being proposed by Management
no longer permits the grant of options to current non-employee directors, I
intend to vote for the Plan.

PROPOSAL 3 - APPOINTMENT OF INDEPENDENT AUDITORS

I have no objection to the ratification of the appointment of Nussbaum Yates &
Wolpow, P.C. as the Company's independent auditors for the fiscal year ending
June 30, 2003. Please see the Management Proxy Statement for a description of
this proposal.

PROPOSAL 4 - STOCKHOLDER PROPOSAL TO PLACE RESTRICTIONS ON STOCK OPTION GRANTS
TO NON-EMPLOYEE DIRECTORS:

Lowell A. Kleiman, the holder of 139,581 shares of SCND Common Stock having a
business address c/o Warshaw Burstein Cohen Schlesinger & Kuh, LLP, 555 Fifth
Avenue, New York, New York 10017 hereby submits the following resolution for
adoption by the stockholders of the Company at its Annual Meeting:

                  RESOLVED, that the stockholders of Scientific Industries, Inc.
         demand that the Board of Directors adopt a policy (a) requiring
         stockholder approval of all grants of stock options to non-employee
         directors of the Company and (b) prohibiting the aggregate number of
         options granted under any stock option plan to non-employee directors
         as a group to be in excess of 20% of the total number of options
         authorized under such plan.

SUPPORTING STATEMENT

There should be limits on the number of options that can be granted to
non-employee directors. Since January 1, 1992, the Company has granted a total
of 385,000 options (all but 48,000 of which were granted under the Company's
stock option plan). Of these options 176,000, or 46%, were granted to
non-employee directors (including 48,000 options that were granted outside of
any stock option plan) while only 209,000, or 54%, of the options were granted
to Company employees. As an employee director, I have been granted 80,000
options, representing 20.8% of all options granted. As a result of the grants to
non-employee directors, according to the Company's Annual Report on Form 10-KSB,
there were only 15,667 shares of common stock left available under the 1992
stock option plan for future grants at the time the plan expired in February
2002. I firmly believe that the grant of stock options to non-employee directors
should be strictly limited and that any option plan should be designed to
attract and retain talented employees.


                           VOTING AND PROXY PROCEDURES

Only stockholders of record on the Record Date will be entitled to notice of and
to vote at the Annual Meeting. Each Share is entitled to one vote. Stockholders
who sell Shares before the Record Date (or acquire them without voting rights
after the Record Date) may not vote such Shares. Stockholders of record on the
Record Date will retain their voting rights in connection with the Annual
Meeting even if they sell such Shares after the Record Date. Based on publicly
available information, I believe that the only outstanding class of securities
of SCND entitled to vote at the Annual Meeting are the shares of common stock.

Shares represented by properly executed BLUE proxy cards will be voted at the
Annual Meeting as marked and, in the absence of specific instructions, will be
voted FOR the election of me and one of the Company's nominees to the Board,
AGAINST the proposal to adopt the 2002 Stock Option Plan, FOR the proposal to
ratify the ratification of the appointment of Nussbaum Yates & Wolpow, P.C. as
the Company's independent auditors for the fiscal year ending June 30, 2003, and
FOR the stockholder proposal limiting stock option grants to non-employee
directors and in the discretion of the persons named as proxies on all other
matters as may properly come before the Annual Meeting.



In accordance with applicable proxy regulations, I intend to use my proxies to
vote for myself and for one of the two individuals nominated by the Board to
serve as a director.

Stockholders who use the BLUE Proxy Card will be able to vote for me and one of
the Company's two nominees. The Company nominee for whom I do not intend to vote
is Mr. Roger Knowles. Stockholders cannot vote for me and also vote for one of
the Company's nominees using the Company's proxy card.

QUORUM

In order to conduct any business at the Annual Meeting, a quorum must be present
in person or represented by valid proxies. A quorum consists of a majority of
the Shares issued and outstanding on the Record Date. All Shares that are voted
"FOR", "AGAINST" or "ABSTAIN" on any matter will count for purposes of
establishing a quorum and will be treated as Shares entitled to vote at the
Annual Meeting (the "Votes Present").

ABSTENTIONS

Abstentions will count as Votes Present and shall have the same effect as a vote
against a matter (other than in the election for the Board of Directors). While
there is no definitive statutory or case law authority in Delaware, the
Company's state of incorporation, as to the proper treatment of abstentions, I
believe that abstentions should be counted for purposes of determining both: (i)
the total number of Votes Present for the purpose of determining whether a
quorum is present; and (ii) the total number of Votes Present that are cast
("Votes Cast") with respect to a matter (other than in the election of the Board
of Directors).

BROKER NON-VOTES

Shares held in street name that are present by proxy will be considered as Votes
Present for purposes of determining whether a quorum is present. With regard to
certain proposals, the holder of record of Shares held in street name is
permitted to vote as it determines, in its discretion, in the absence of
direction from the beneficial holder of the Shares.

The term "broker non-vote" refers to shares held in street name that are not
voted with respect to a particular matter, generally because the beneficial
owner did not give any instructions to the broker as to how to vote such shares
and the broker is not permitted under applicable rules to vote such shares in
its discretion because of the subject matter of the proposal, but whose shares
are present on at least one matter. Such shares shall be counted as Votes
Present for the purpose of determining whether a quorum is present. Broker
non-votes will not be counted as Votes Cast with respect to matters as to which
the record holder has expressly not voted. Accordingly, I believe that broker
non-votes will have no effect upon the outcome of voting on any of the business
matters set forth in this Proxy Statement.

VOTES REQUIRED FOR APPROVAL

Election of Directors. A plurality of the total Votes Cast by holders of the
Shares is required for the election of directors and the nominees who receive
the most votes will be elected (assuming a quorum is present). A vote to
"WITHHOLD" for any nominee for director will be counted for purposes of
determining the Votes Present, but will have no other effect on the outcome of
the vote on the election of directors. Stockholders do not have cumulative
voting rights with respect to the election of directors. A stockholder may cast
such votes either by so marking the ballot at the meeting or by specific voting
instructions sent with a signed proxy to me in care of MacKenzie Partners, Inc.
at the end of this Proxy Statement.

Other Proposals. Other than the election of directors, the vote required for all
other business matters set forth in this Proxy Statement is the affirmative vote
of a majority of the Votes Present.



REVOCATION OF PROXIES

Stockholders of SCND may revoke their proxies at any time prior to exercise by
attending the Annual Meeting and voting in person (although attendance at the
Annual Meeting will not in and of itself constitute revocation of a proxy) or by
delivering a written notice of revocation. The delivery of a subsequently dated
proxy which is properly completed will constitute a revocation of any earlier
proxy. The revocation may be delivered either to me in care of MacKenzie
Partners, Inc. at the address set forth at the end of this Proxy Statement or to
the Company at 70 Orville Drive, Bohemia, New York 11716 or any other address
provided by SCND. Although a revocation is effective if delivered to SCND, I
request that either the original or photostatic copies of all revocations be
mailed to me in care of MacKenzie Partners, Inc. at the address set forth on the
back cover of this Proxy Statement so that I will be aware of all revocations
and can more accurately determine if and when proxies have been received from
the holders of record on the Record Date of a majority of the outstanding
Shares. Additionally, MacKenzie Partners, Inc. may use this information to
contact stockholders who have revoked their proxies in order to solicit later
dated proxies.

IF YOU WISH TO VOTE FOR MY RE-ELECTION TO THE SCND BOARD, FOR THE ADOPTION OF
THE 2002 STOCK OPTION PLAN AND FOR THE STOCKHOLDER PROPOSAL TO PLACE
RESTRICTIONS ON THE GRANT OF OPTIONS TO NON-EMPLOYEE DIRECTORS , PLEASE SIGN,
DATE AND RETURN PROMPTLY THE ENCLOSED BLUE PROXY CARD IN THE POSTAGE-PAID
ENVELOPE PROVIDED.

                             SOLICITATION OF PROXIES

The solicitation of proxies pursuant to this Proxy Statement is being made by
me. Proxies may be solicited by mail, facsimile, telephone, telegraph, in person
and by advertisements. I will not solicit proxies via the Internet.

I have entered into an agreement with MacKenzie Partners, Inc. for solicitation
and advisory services in connection with this solicitation, for which MacKenzie
Partners, Inc. will receive a fee not to exceed $7,500, together with
reimbursement for its reasonable out-of-pocket expenses, and will be indemnified
against certain liabilities and expenses, including certain liabilities under
the federal securities laws. MacKenzie Partners, Inc. will solicit proxies from
individuals, brokers, banks, bank nominees and other institutional holders. I
have requested banks, brokerage houses and other custodians, nominees and
fiduciaries to forward all solicitation materials to the beneficial owners of
the Shares they hold of record. I will reimburse these record holders for their
reasonable out-of-pocket expenses in so doing. It is anticipated that MacKenzie
Partners, Inc. will employ approximately 20 persons to solicit SCND's
stockholders for the Annual Meeting.

The entire expense of soliciting proxies is being borne by me. If I am elected
to the SCND Board, I DO NOT intend to seek reimbursement of the costs of this
solicitation from SCND. Costs of this solicitation of proxies are currently
estimated to be approximately $50,000. I estimate that through the date hereof,
my expenses in connection with this solicitation are approximately $10,000.

                             PARTICIPANT INFORMATION

No other persons are participants in this solicitation. For information
regarding purchases and sales of Shares during the past two years by me, see
Schedule I.

                         CERTAIN TRANSACTIONS WITH SCND

Except for salary and other employment compensation I received while an officer
and director of SCND during my tenure with the Company, and as otherwise set
forth in this Proxy Statement (including the Schedules hereto), neither me nor
any of my associates: (i) directly or indirectly beneficially owns any Shares or
any securities of SCND; (ii) has had any relationship with SCND in any capacity
other than as a stockholder, or is or has been a party to any transactions, or

the past year, currently proposed transactions, or series of similar
transactions, to which SCND or any of its subsidiaries was or is to be a party,
in which the amount involved exceeds $60,000 and in which any of them or their
respective affiliates had, or will have, a direct or indirect material interest.
In addition, other than as set forth herein, there are no contracts,
arrangements or understandings entered into by me or any of my associates within
the past year with any person with respect to any of SCND's securities,
including, but not limited to, joint ventures, loan or option arrangements, puts
or calls, guarantees against loss or guarantees of profit, division of losses or
profits, or the giving or withholding of proxies.



Except as set forth in this Proxy Statement (including the Schedules hereto),
neither me nor any of my associates, has entered into any agreement or
understanding with any person with respect to (i) any future employment by SCND
or its affiliates or (ii) any future transactions to which SCND or any of its
affiliates will or may be a party. However, I have reviewed, and will continue
to review, on the basis of publicly available information, various possible
business strategies that it might consider in the event that I am re-elected to
the Board.

                    OTHER MATTERS AND ADDITIONAL INFORMATION

I am unaware of any other matters to be considered at the Annual Meeting other
than the election of directors, adoption of the 2002 Stock Option Plan, my
Stockholder Proposal and the ratification of the appointment of the Company's
auditors. However, should other matters, which I am not aware of a reasonable
time before this solicitation, be brought before the Annual Meeting, the persons
named as proxies on the enclosed BLUE proxy card will vote on such matters in
their discretion.

I have omitted from this Proxy Statement certain disclosure required by
applicable law that is already included in the Management Proxy Statement. This
disclosure includes, among other things, biographical information on SCND's
directors and executive officers, information concerning executive compensation,
information on audit services and fees of Nussbaum Yates & Wolpow, P.C and
procedures for nominating directors for election to the SCND Board and
submitting proposals for inclusion in SCND's proxy statement at the next annual
meeting. Stockholders should refer to the Management Proxy Statement in order to
review this disclosure.

See Schedule II for information regarding persons who beneficially own more than
5% of the Shares and the ownership of the Shares by the management of SCND.

The information concerning SCND contained in this Proxy Statement and the
Schedules attached hereto has been taken from, or is based upon, publicly
available information.
