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 an independent voice necessary for the
future of the Company. I am running because I firmly believe that my presence as
an independent Director 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 what I consider questionable practices by 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 and urging all
stockholders to vote AGAINST the 2002 Stock Option Plan.

     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 election
of one of the management nominees, FOR my shareholder proposal to require
shareholder approval of option grants to non-employee directors and to otherwise
limit the number of shares that may be issued to them and AGAINST the 2002 Stock
Option Plan. 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, I had proposed a strategic
business plan designed to establish a foundation for the growth of the Company.
Essentially, I presented a plan whereby Scientific Industries would expand its
product base, taking advantage of our established name recognition and would no
longer operate as a one-product company. It now appears to me that the Board has
adopted, in theory, some of the provisions I outlined in my plan but has failed
to allocate the resources necessary to achieve meaningful growth in the shortest
manageable period of time.


     Having spent thirty-seven years (thirty-two as a director), with Scientific
Industries, I frankly believe that I have the experience and knowledge required
to oversee a long-term strategic plan while the current board simply lacks the
vision and energy necessary to implement any strategy that does not produce
immediate financial gain.

     In addition, this management has changed the character of my plan from one
designed to create long-term growth and profit to one that seems to me to
emphasize superficial changes geared towards short-term gains, without adequate
thought towards developing our Company into an attractive investment for current
or potential stockholders. By allocating our Company's finances without an aim
of long-term growth, I believe that this management is depriving your Company of
capital that is crucial to the growth of Scientific Industries.

                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. One of my
major concerns as an employee, a board member and a stockholder has been
responsible corporate governance. Given the recent spate of corporate scandals,
I believe that there is a direct correlation between a company's corporate
governance practices and its stock price. In essence, I believe that the more
responsibly a corporation is governed, the higher the resulting stockholder
value. In my opinion, as the current Board continues its pattern of running the
Company without adequate regard to its future financial viability, prospective
investors will avoid our Company and the liquidity of our stock will remain
minimal.

     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 truly independent
director, I will provide a voice for all stockholders and will vigorously oppose
any plan which could be contrary to our goals as investors.

               THE 2002 STOCK OPTION PLAN - A RECIPE FOR DILUTION

     In my opinion, stock options can provide a useful means of employee
remuneration, particularly for growing public corporations that lack sufficient
capital to hire and retain talented employees. In the past, I have supported
responsible stock option plans that limited stockholder dilution. However, given
the current status of Scientific Industries, I believe there is no plausible
rationale for what I believe are the excessive options that the Board has issued
and continues to issue to itself.

     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, I believe that the current Board refuses to
allocate sufficient capital towards strengthening our Company's market position.

     If approved, the 2002 Option Plan would increase the dilution that has
already resulted from previous option grants. By looking at the Company's own
publicly filed documents, a disturbing conclusion cannot be avoided - Option
grants to non-employee Directors have already resulted in a 22% dilution of the
Company's stock and yet they refuse to enact limits on option shares granted to
non-employee directors.

                                        2


     During my participation in the Board meeting held on September 26, 2002, I
strongly objected to the alleged verbal "Plan" that was proposed by Directors
Joseph Kessleman and Arthur Borden and supported by James Segasture and Roger
Knowles. I expressed my position that I could not vote on a "Plan" that
contained no identifiable terms and could not, in any event, support any
proposal that did not reserve a majority of shares for Company employees.
Further, I recommended that there be a strict limit on the number of option
shares that could be granted to a non-employee Director. When the Board
introduced a broad resolution authorizing the approval of an undisclosed "Option
Plan", I abstained and reiterated that I could not support the "Plan" in its
current form of an abstract, potentially limitless proposal.

     Though I thought I had made my objections to the "Plan" crystal clear and,
had they been accurately published, the minutes of the meeting would have
abundantly memorialized my opposition, management claims in its proxy materials
that the Board "unanimously" approved the "Plan". . Upon reading management's
proxy statement, I was shocked that my refusal to vote on the "Plan" was simply
ignored by the Board.

             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 a truly independent
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).

Thank you for your support,

                                LOWELL A. KLEIMAN

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

                    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. I believe
that recent actions of the Board of Directors of SCND (the "SCND Board") have
not been in the best interests of SCND's stockholders. As further described
herein, I believe that a more thorough investigation of strategic alternatives,
a greater dedication to maximizing stockholder value and improving corporate
governance policies, will be best achieved through the my election. 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 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 October __, 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 SHAREHOLDER 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 THE ELECTION
OF OUR NOMINEE 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, AND AGAINST THE STOCK OPTION PLAN AND FOR THE SHAREHOLDER 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.

PROPOSAL I - ELECTION OF DIRECTORS

REASONS FOR THE SOLICITATION

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

     o    remove one of two incumbent directors up for election;

     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; and

     o    elect a clearly independent director.

As more fully described in my letter accompanying this proxy statement, I
believe that my re-election represents the best means for SCND's stockholders to
maximize the value of their Shares. 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 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.

In accordance with applicable proxy regulations, I intend to use my proxies to
vote for Mr. Joseph Cremonese, who is one of the two individuals nominated by
the Board to serve as a director. Mr. Cremonese is a nominee of the Company and
not of me.

Shareholders who use the BLUE Proxy Card will be able to vote for me and one of
the Company's nominees, Mr. Joseph Cremonese. The Company nominee for whom I am
not seeking authority to vote is Mr. Roger Knowles. Shareholders cannot vote for
me and also vote for one of the Company's nominees using the Company's proxy
card. Any shareholder who wishes to vote for me and Mr. Knowles will be required
to vote by ballot at the 2002 Annual Meeting. Shareholders should refer to the
Company's proxy statement for information concerning the Company's nominees,
including Mr. Cremonese. 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.

                                        3


PROPOSAL 2 - ADOPTION OF THE 2002 STOCK OPTION PLAN

The Company has proposed the adoption of the 2002 Stock Option Plan which would
permit the Company to issue options to purchase up to 261,000 shares of the
Company's common Stock. As more fully described in my letter accompanying this
proxy statement, I OPPOSE the approval of the adoption of the 2002 Stock Option
Plan because I believe it has the potential to dilute the value of the Company's
stock and does not limit options that can be granted to non-employee directors.

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 - SHAREHOLDER 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 shareholders of the Company at its Annual Meeting:

               RESOLVED, that the shareholders 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

As stated above under Proposal 2, I believe that stock option grants can have a
diluting effect on the value of the Company's stock and that there should be
limits on the number of options that can be granted to non-employee directors.
Since January 1, 1992, grants to non-employee directors have resulted in a 22%
dilution of the Company's stock. 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 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 Joseph Cremonese, 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 shareholder 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.

                                        4


I am asking you to elect me and Joseph Cremonese, one of the Company's nominees,
to the Board, in opposition to one of the two incumbent nominees whose terms
expire at the Annual Meeting. In accordance with applicable proxy regulations, I
intend to use my proxies to vote for Mr. Joseph Cremonese, who is one of the two
individuals nominated by the Board to serve as a director. Mr. Cremenose is a
nominee of the Company and not of me.

Shareholders who use the BLUE Proxy Card will be able to vote for me and one of
the Company's nominees, Mr. Joseph Cremonese. The Company nominee for whom I am
not seeking authority to vote is Mr. Roger Knowles. Shareholders 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 Cast.

                                        5


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, AGAINST THE ADOPTION
OF THE 2002 STOCK OPTION PLAN AND FOR THE SHAREHOLDER 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
series of similar transactions, or was indebted to SCND during the past year
with respect to any Shares of SCND; or (iii) knows of any transactions during
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.

                                        6


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
Shareholder 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.
