(1)   Estimated solely for the purpose of computing the amount of the
      registration fee pursuant to Rule 457(c) under the Securities Act of 1933,
      as amended (the "Securities Act") on the basis of the average of the high
      and low sales prices for such Common Stock on December 24, 1998 as
      reported on the Nasdaq SmallCap Market.

(2)   For purposes of estimating the number of common shares, par value $.01 per
      share ("Common Shares"), of American Bio Medica Corporation (the
      "Registrant") to be included in this registration statement (the
      "Registration Statement"), the Registrant calculated 200% of the number of
      Common Shares issuable upon the conversion at maturity of 1,843 of the
      Registrant's Series D Convertible Preferred Shares, par value $.01 per
      share (the "Series D Preferred Shares"), or otherwise pursuant to the
      Certificate of Designation of the Series D Preferred Shares, based on a
      conversion price of $2.1375 per share.
    
(3)   Pursuant to Rule 416, the Registration Statement also registers an
      indeterminate number of Common Shares as may be issued or become issuable
      upon conversion of the Series D Preferred Shares and exercise of the
      Warrants in accordance with their respective terms to prevent dilution
      resulting from stock splits, stock dividends or similar transactions.

     The Registrant hereby amends the Registration Statement on such date or
dates as may be necessary to delay its effective date until the Registrant shall
file a further amendment which specifically states that the Registration
Statement shall thereafter become effective in accordance with Section 8(a) of
the Securities Act of 1933 or until this Registration Statement shall become
effective on such date as the Securities and Exchange Commission, acting
pursuant to said Section 8(a), may determine.

PROSPECTUS
   
                         AMERICAN BIO MEDICA CORPORATION
                             1,851,458 Common Shares

     This prospectus (the "Prospectus") relates to the offer and sale by certain
persons listed under "Selling Shareholders" (collectively, the "Selling
Shareholders") of an aggregate of up to (a) 2,143,056 common shares, par value
$.01 per share (the "Common Shares") of American Bio Medica Corporation (the
"Company") issued and/or issuable upon the conversion of the Company's Series
"D" Convertible Preferred Shares (the "Series 'D' Preferred Shares") and (b) up
to 107,355 Shares issuable upon the exercise of common share purchase warrants
(the "Warrants"). (See "Selling Shareholders" and "Plan of Distribution.") The
Company will not receive any proceeds from the sale of Common Shares. The
Company has agreed to pay the expenses of registration of the Common Shares,
including legal and accounting fees. The Company has agreed to file an
additional registration statement or registration statements to register
sufficient shares such that, from time to time, the number of shares registered
for resale upon conversion of the Series "D" Preferred Shares is twice the
number of shares issuable under the applicable conversion formula.

     The Selling Shareholders currently hold 1,843 Series "D" Preferred Shares
and 418,612 Common Shares.
    
     Each Series "D" Preferred Share is convertible at the lesser of (a) 95% of
the "Market Price" (the average of the closing bid prices of the Common Shares
over any three trading days, selected by the holder of the Series "D" Preferred
Shares (the "Holder"), in the 20 trading days immediately preceding the date of
conversion ("Conversion Date") and (b) $4.625. Each Warrant entitles the holders
("Warrantholders") to purchase one Common Share at a price of $4.81 per share
until April 24, 2001. The exercise price of the Warrants has been determined
through negotiation between the Company, the Warrantholders and the Selling
Agent (the "Selling Agent") and such price does not necessarily bear any direct
relationship to the current market value, asset value or net book value of the
Company or other generally accepted criteria of value. The formula for the
conversion of the Series "D" Preferred Shares has been determined by the
Company, the Holder and the Selling Agent and bears no relation to the Company's
assets, book value, or any other customary investment criteria, including the
Company's prior operating history. (See "Risk Factors--Determination of
Conversion/Exercise Prices)
   
     The Common Shares trade on the National Association of Securities Dealers,
Inc. Automatic Quotation Market ("Nasdaq SmallCap") under the symbol "ABMC". On
December 24, 1998, the average of the high and low sales prices for the Common
Shares, as reported on the Nasdaq SmallCap Market was $2.2505 per share.
Nonetheless, there can be no assurance that a public market in the Common Shares
will be sustained during the period of exercise of conversion of the Series "D"
Preferred Shares.
    

                                        1
<PAGE>
     The Common Shares offered hereby may be sold by the Selling Shareholders or
by pledgees, donees, transferees or other successors in interest that receive
such shares as a gift, partnership distribution or other non-sale related
transfer. The Common Shares may be sold from time to time in transactions in the
over-the-counter market, in negotiated transactions, or a combination of such
methods of sale, at fixed prices which may be changed, at market prices
prevailing at the time of sale, at prices related to prevailing market prices or
at negotiated prices. The Selling Shareholders may effect such transactions by
selling the Common Shares to or through broker-dealers, including block trades
in which brokers or dealers will attempt to sell the Common Shares as agent but
may position and resell the block as principal, or in one or more underwritten
offerings on a firm commitment or best efforts basis. (For a more complete
description of the manner in which Common Shares may be offered and sold
pursuant hereto see "Plan of Distribution.")

     THE SECURITIES OFFERED HEREBY INVOLVE A HIGH DEGREE OF RISK. THE COMMON
SHARES SHOULD BE PURCHASED ONLY BY INVESTORS WHO ARE ABLE TO AFFORD THE RISK OF
LOSS OF THEIR ENTIRE INVESTMENT. (SEE "RISK FACTORS" starting on page 6.)

                                   THE COMPANY

     The following summary is qualified in its entirety by reference to the
detailed information, financial statements and related notes appearing elsewhere
in the Prospectus including information under the caption "Risk Factors." Each
investor is urged to read the Prospectus in its entirety.
   
     American Bio Medica Corporation (the "Company") is primarily engaged in
acquiring, developing and marketing biomedical technologies and products. The
Company owns a technology for screening drugs of abuse, trademarked the "Rapid
Drug Screen." The Company's common shares ("Common Shares") trade on the Nasdaq
SmallCap Market under the symbol "ABMC".
    
     The Company produces several version of a "drugs of abuse" screening test,
called the "Rapid Drug Screen Test" at its manufacturing facility in Columbia
County, New York. The Rapid Drug Screen Test is a one-step test kit that allows
a small urine sample to be tested for the presence or absence of drugs of abuse.
The competitively priced test is self-contained preventing exposure of the test
administrator to the urine sample. In the opinion of the Management
("Management"), the Rapid Drug Screen Test, which requires no mixing of
reagents, is easier to use than any competitive product. In addition, hundreds
of controlled tests conducted by independent laboratories compared the Rapid
Drug Screen Test with results produced by EMIT II, a standard laboratory test,
and found a 100% correlation of both positive and negative test results. As a
result, Management believes that the Rapid Drug Screen Test is as accurate as
that laboratory test.

     Versions of the Rapid Drug Screen Tests include a two panel (cocaine and
marijuana), five panel (cocaine, marijuana, opiates, amphetamine and PCP) and an
eight panel (THC, cocaine, opiates, PCP, amphetamines, benzodiazepines,
methamphetamines and barbiturates) test. All have been cleared by the Federal
Drug Administration (the "FDA") and can thus be sold in clinical as well as
workplace markets. The Company has also completed a test for tricyclic
antidepressants which it has submitted to the FDA for approval and which it
intends to market in the near future as part of a nine-panel test. The Company
has recently developed nine tests trademarked "Rapid One", each of which detects
one drug of abuse and a low volume 8 panel test which requires as little as two
milliliters of urine, compared with the usual 15-30 milliliters. The low volume
8 panel Rapid Drug Screen, which has received FDA 510(k) clearance, is ideal for
use in hospital settings as well as for compliance with laboratory certification
and quality control requirements.

     The Company has installed and uses equipment at its manufacturing facility
suitable for the mass production of workplace drug screening tests. The
Company's output was initially hampered by its inability to secure reliable
supplies of reagents. This problem was rectified in May, 1997 through improved
reliability of its suppliers and the addition of a third supplier.

     The Company also owns a patented low cost method for producing keratin
proteins. The Company has no intention of developing or marketing its keratin
technology, but intends to concentrate on the production and marketing of its
drug screen tests and pursuing development and acquisition strategies related to
substance abuse testing.


                                       5
<PAGE>
     The Company may develop or acquire additional biomedical technologies or
products in the future unrelated to substance abuse.

     From its inception in 1986 until 1991, the Company was involved in
marketing educational books and software to schools and municipal libraries and
audiovisual educational packages to educational institutions and to corporations
throughout the United States. In 1991, the Company, because of heightened
competition, increased costs of doing business and slow collections from
municipalities, reduced its involvement in this market to that of selling
audiovisual packages to libraries and commenced seeking new technologies in
emerging medical markets.

     The Company's headquarters are located at 300 Fairview Avenue, Hudson, New
York 12534. Its telephone number at that address is 800-227-1243 and its fax
number is 518-822-0391. Its e-mail address is [email protected].


                                  RISK FACTORS

     Except for the description of historical facts contained herein, the
Prospectus contains certain forward looking statements that involve risks and
uncertainties as detailed herein and from time to time in the Company's filings
with the Commission and elsewhere. Forward looking statements herein are made
pursuant to the "safe harbor" provisions of the Private Securities Litigation
Reform Act of 1995. Such statements are based on Management's current
expectations and are subject to a number of factors and uncertainties which
could cause actual results to differ materially from those described in the
forward-looking statements. These factors include, among others, the Company's
fluctuations in sales and operating results, risks associated with international
operations and regulatory, competitive and contractual risks and product
development.
   
      THE PURCHASE OF COMMON SHARES IS HIGHLY SPECULATIVE, INVOLVES A HIGH
DEGREE OF RISK AND SHOULD BE MADE ONLY BY INVESTORS WHO CAN AFFORD THE LOSS OF
THEIR ENTIRE INVESTMENT. A PROSPECTIVE PURCHASER, PRIOR TO MAKING AN INVESTMENT
DECISION, SHOULD CAREFULLY CONSIDER, ALONG WITH OTHER MATTERS REFERRED TO
HEREIN, THE FOLLOWING RISK FACTORS:
    
     1. Limited Operating History.

     Although the Company was formed in 1986, as far as the development,
manufacture and sale of drug testing kits are concerned, it has extremely
limited operational history upon which investors may base an evaluation of its
performance or any assumption as to the likelihood that the Company will be
profitable. The Company's prospects must be considered in light of the risks,
expenses, delays, problems and difficulties frequently encountered in the
establishment of a new business, the development and commercialization of new
products based on innovative technology and the competitive environment in which
the Company operates. Since the Company's entry into the biomedical business,
the Company has generated limited revenues. There can be no assurance that the
Company will be able to generate significant revenues or achieve profitable
operations.

                                       6
<PAGE>
      2. Technological Factors; Uncertainty of Product Development; Unproven
Technology.

     Although the Company's development efforts relating to the technological
aspects of the workplace drug testing kit are completed, the Company is
continually seeking to refine and improve its design and performance and to
develop additional versions. The Company's efforts remain subject to all of the
risks inherent in new product development, including unanticipated technical,
regulatory or other problems which could result in material delays in product
development or commercialization or significantly increased costs. The Company
may be required to commit considerable additional efforts, time and resources to
develop production versions of its additional products. The Company's success
will depend upon such products meeting targeted product costs and performance,
and may also depend upon their timely introduction into the marketplace. There
can be no assurance that development of the Company's proposed products will be
successfully completed on a timely basis, if at all, that they will meet
projected price or performance objectives, satisfactorily perform all of the
functions for which they are being designed, or prove to be sufficiently
reliable in widespread commercial application. Moreover, there can be no
assurance that unanticipated problems will not arise with respect to
technologies incorporated into its test kits or that product defects will not
become apparent after commercial introduction of its additional test kits. In
the event that the Company is required to remedy defects in any of its products
after commercial introduction, the costs to the Company could be significant,
which could have a material adverse effect on the Company revenues or earnings.

     3. Uncertainty of Continued Market Acceptance.

     The Company's drug test kits have been well received by customers,
including corporations, distributors and correctional institutions. As is
typically the case with an emerging company, demand and market acceptance for
newly introduced products is subject to a high level of uncertainty. Achieving
continued market acceptance for its drug tests will require substantial
marketing efforts and expenditure of significant funds to inform potential
distributors and customers of the distinctive characteristics, benefits and
advantages of its kits. There can be no assurance that its drug test kits will
become generally accepted or that the Company's efforts will result in
successful product commercialization or initial or continued market acceptance
for its other drug testing products. In addition, continued market acceptance
will depend on the Company's ability to upgrade its technology

     4. Competition in the Drug Testing Market; Technological Obsolescence.

     The Company faces competition for every existing and proposed product from
drug manufacturers and other manufacturers of drug test kits. Some of its
competitors are well known and have far greater financial resources than the
Company. To the best of Management's knowledge, and in its opinion, no
competitors have introduced products which equal the ease of use combined with
the accuracy of the Company's drug test kits. The markets for drug test kits and
related products are highly competitive. There can be no assurance that other
technologies or products which are functionally similar to those of the Company
are not currently under development. In addition, there can be no assurance that
other companies with the expertise or resources that would encourage them to
attempt to develop or market competing products will not develop new products
directly competitive with the Company's drug test kits. Despite the protections
which would be available to the Company in the event its pending application for
a design patent is granted, the Company expects other companies to attempt to
develop technologies or products which will compete with the Company's products.
In addition, continued market acceptance will depend on the Company's ability to
upgrade its technology to meet any future competitive technologies.

     5. Dilution as a Result of Conversion of Series "D" Preferred Shares and
Exercise of Warrants.
   
     The Selling Shareholders purchased 2,500 Series "D" Preferred Shares,
converted 750 Series "D" Preferred Shares into 418,612 Common Shares and now
hold 1,843 Series "D" Preferred Shares of the Company, which are convertible
into Common Shares. See "Selling Shareholders." Each Series "D" Preferred Share
is convertible into a number of Common Shares equal to (i) $1,000 (ii) divided
by a conversion price which is the lesser of (a) 95% of the "Market Price" (the
average of the closing bid prices of the Common Shares over any three trading
days, selected by the holder of the Series "D" Preferred Shares in the 20
trading days immediately preceding the date of conversion) and (b) $4.625. Under
the applicable conversion formulas of the Series "D" Preferred Shares, the
number of Common Shares issuable upon conversion is inversely proportional to
the market price of the Common Shares at the time of conversion (i.e., the
number of shares increases as the market price of the Common Shares decreases);
and except with respect to certain redemption rights of the Company for the
Series "D" Preferred Shares and the limitation under Nasdaq SmallCap regulations
which limit the aggregate amount of Common Shares which the Company may issue at
a discount from market price upon conversion of the Series "D" Preferred Shares
and Warrants without shareholder approval, (such shareholder approval will be
requested by the Company), there is no cap on the number of shares of Common
Shares which may be issued. In addition, the number of Common Shares issuable
upon the conversion of the Series "D" Preferred Shares and the exercise of
Warrants is subject to adjustment upon the occurrence of certain dilutive
events. For a further description of the rights of holders of Series "D"
Preferred Shares, see the Certificate of Amendment of Certificate of
Incorporation of American Bio Medica Corporation filed as an exhibit to the
Company's Current Report on Form 8-K, dated April 27, 1998. The Selling
Shareholders also hold outstanding Warrants to acquire a total of 107,355 Common
Shares at a price of $4.81 share. All of such Common Shares are covered by the
registration statement containing this Prospectus or will be covered by
subsequent registration statements filed by the Company, if necessary. The
exercise of such Warrants and conversion of such Series "D" Preferred Shares and
the sale of such Common Shares could have a significant negative effect on the
market price of the Common Shares and could materially impair the Company's
ability to raise capital through the future sale of equity securities.
    
     6. Possible Inability to Find and Attract Qualified Personnel.

     The Company currently has sufficient management expertise and depth to
develop its business. It has recently added marketing and manufacturing
management and has added to its scientific advisory board. However, it will need
additional skilled and dedicated marketing personnel as well as technical and
production personnel in the future. There is no guarantee that the Company can
retain its present staff or that capable personnel with relevant skills will be
available.

     7. Dependence on Management.
   
     The Company is dependent on the expertise and experience of Stan Cipkowski,
President and CEO, Jay Bendis, Vice-President-Sales & Marketing, and Douglas
Casterlin, Vice-President-Operations, for its operations. The loss of Messrs.
Cipkowski, Bendis and Casterlin, or any of them, will seriously inhibit the
Company's operations. The Company does not maintain key man insurance for any of
its management employees.
    

                                       8

     8. Possible Adverse Changes in Regulatory Framework.

     Clearance from the FDA is not required for the sale of workplace drug test
kits, but is required for clinical drug test kits. The Company has received
"510(k)" clearance from the FDA for its two, five and eight panel drug test
kits. It is awaiting FDA clearance of one test of its nine panel drug test kit
and is preparing the application for its Rapid One drug test kit. However,
regulatory standards may change in the future and there is no assurance that if
and when the Company applies for additional clearances from the FDA they will be
granted.

     9. Resale of Restricted Securities.
   
     5,326,917 Common Shares presently issued and outstanding as of the date
hereof are "restricted securities" as that term is defined under the Securities
Act of 1933, as amended, (the "Securities Act") and in the future may be sold in
compliance with Rule 144 of the Securities Act, or pursuant to a Registration
Statement filed under the Securities Act. Rule 144 provides, in essence, that a
person holding restricted securities for a period of one year may sell those
securities in unsolicited brokerage transactions or in transactions with a
market maker, in an amount equal to one percent of the Company's outstanding
Common Shares every three months. Sales of unrestricted shares by affiliates of
the Company are also subject to the same limitation upon the number of shares
that may be sold in any three month period. Such information is deemed available
if the issuer satisfies the reporting requirements of sections 13 or 15(d) of
the Securities and Exchange Act of 1934 (the "Securities Exchange Act") or of
Rule 15c2-11 thereunder. Rule 144(k) also permits the termination of certain
restrictions on sales of restricted securities by persons who were not
affiliates of the Company at the time of the sale and have not been affiliates
in the preceding three months. Such persons must satisfy a two year holding
period. There is no limitation on such sales and there is no requirement
regarding adequate current public information. Investors should be aware that
sales under Rule 144 or 144(k), or pursuant to a registration statement filed
under the Securities Act, may have a depressive effect on the market price of
the Company's securities in any market which may develop for such shares.
    
     10. Need for Additional Financing.

     The Company expects that its cash on hand will be sufficient to fund the
Company's proposed operations for at least 12 months from the date of the
Prospectus. This estimate is based on certain assumptions and there can be no
assurance that unanticipated unbudgeted costs will not be incurred. Future
events, including the problems, delays, expenses and difficulties which may be
encountered in establishing and maintaining a substantial market for the
Company's drug test kits and other technologies could make cash on hand
insufficient to fund the Company's proposed operations. There can be no
assurance that the Company will be able to obtain any necessary additional
financing on terms acceptable to it, if at all. In addition, financing may
result in further dilution to the Company's then existing stockholders. The
Company has no established borrowing arrangements or available lines of credit.


                                       9
<PAGE>
     11. No Dividends.

     The payment of dividends rests within the discretion of the Company's Board
of Directors. No dividends have been paid on the Common Shares and the Company
does not anticipate the payment of cash dividends in the foreseeable future. If
the operations of the Company become profitable, it is anticipated that, for the
foreseeable future, any income received therefrom would be devoted to the
Company's future operations and that cash dividends would not be paid to the
Company's shareholders.

     12. Control by Management.
   
     Management of the Company owns in excess of 35% of the outstanding Common
Shares and is in a position to control the election of the Board of Directors.
The certificate of incorporation of the Company does not provide for cumulative
voting and, as a result, purchasers of the Company's securities will not be able
to elect any directors or exert any control over the general policies of the
Company.
    
     13. Ability to Retain and Attract Market Makers.
   
     The Common Shares trade on the Nasdaq SmallCap Market. In the event that
the market makers cease to function as such, public trading in the Common Shares
will be adversely affected or may cease entirely. Presently, market makers for
the Company's Common Shares include Fidelity Capital Markets, J.W. Genesis
Clearing Corp., Hill Thompson Magid & Co., Paragon Capital Corp., Troster Singer
Corp., Comprehensive Capital Corp., Herzog, Heine, Geduld, Inc., Mayer &
Schweitzer, Inc., Knight Securities, LP., National Financial Securities Corp.,
Sharpe Capital,Inc. and Wien Securities Corp., Sherwood Securities Corp., and M.
H. Meyerson & Co.,Inc.
    
     14. Anti-Takeover Provisions in Certificate of Incorporation.

     The Company's certificate of incorporation authorizes the issuance of
5,000,000 Preferred Shares. The Board of Directors has the authority, without
further action by the Common Shareholders, to issue Preferred Shares from time
to time in one or more classes or series, to fix the number of shares
constituting any class or series and the stated value thereof, if different from
the par value, and to fix the terms of any such series or class, including
dividend rights, dividend rates, conversion or exchange rights, voting rights,
rights and terms of redemption (including sinking fund provisions), the
redemption price and the liquidation preference of such class or series. Thus,
the Board of Directors, in order to avoid a hostile takeover, could issue
Preferred Shares with supervoting rights, conversion rights into Common Shares,
liquidation preference or a combination of rights and preferences which could
inhibit success of such attempt.


                                       10
<PAGE>
     15. Determination of Conversion/Exercise Prices.

     The formula for the conversion of the Series "D" Preferred Shares and the
exercise of the Warrants into Common Shares has been determined by the Company
and the holders thereof and bears no relation to the Company's assets, book
value, or any other customary investment criteria, including the Company's prior
operating history.

     16. Patents and Trademarks.

     The Company has registered "ABM" and its logo in the United States, Canada,
Chile and Mexico and has registered "Rapid Drug Screen" in Mexico. The Company
has additional trademark applications pending in the United States, Canada,
Philippines and in 15 European countries. The Company's trademark counsel,
Edmund Jaskiewicz, Esq., Executive Vice-President, has opined that there are no
similar marks and, as a consequence, the Company feels confident that such marks
will be registered. The Company has applied for various patents directly in
numerous countries, including the United States, Canada, Australia, Argentina,
Brazil, China, Japan, Germany, Mexico, Philippines, Poland and the United
Kingdom and has filed patent applications with three regional associations
covering 33 additional member countries. Stan Cipkowski, President, has assigned
to the Company for no consideration, his application for a utility and design
patent in the United States and Canada on the drug screen kit as an entity. Mr.
Jaskiewicz, as patent counsel, has opined that a search has revealed no
competing patented products. However, there can no assurance that a patent will
be granted or that, if granted, it will withstand challenge.
   
     17. Litigation Relating to Acquisition of Technologies.

 In February 1994, Robert Friedenberg, as former owner of the two medical
technology companies, MDI and Gendex, acquired by the Company, in the name of
these corporations, filed for a declaratory judgement that a Share Exchange
Agreement had been rescinded. In order to make a claim for damages, the Company
filed a third-party claim against Dr. Friedenberg for breach of the Share
Exchange Agreement and fraud. In November 1995, after a trial, the court denied
Dr. Friedenberg's request for a declaration of rescission and allowed the
Company's third-party claim to proceed to trial. In September, 1996, Dr.
Friedenberg died.

      The Company's third-party claim was decided by a jury on May 5, 1997. The
verdict determined that Dr. Friedenberg breached the Share Exchange Agreement,
when he failed to deliver drug screening know how technology to the Company. The
jury also found in favor of the Company on two of the three fraud claims against
Friedenberg and awarded the Company approximately $321,000 in damages.
Friedenberg's estate, just prior to the jury trial, filed a supplemental claim
for the shares of the Company's stock which he would have received under the
Share Exchange Agreement. The trial judge took this supplemental claim under
advisement. The trial judge, on July 17, 1998, ruled that the estate of Dr.
Friedenberg is entitled to 5,907,154 common shares of the Company. The Company
has filed an appeal. Management of the Company in consultation with counsel is
of the opinion that the trial judge's award of the shares to Dr.
Friedenberg's estate will be reversed on appeal.

      Pending the resolution of the Company's appeal, the trial judge has
ordered that the shares be issued in the name of Dr. Friedenberg's wife and
placed in escrow or that the Company post a bond. The Company has applied for a
stay of this order. If the trial judge's order is not stayed, the issuance of
such shares or the posting of the required bond could have a significant
negative effect on the market price of the shares. Pending the resolution of the
Company's appeal of the trial judge's award of the shares to Dr. Friedenberg's
estate, the Company's ability to raise capital through the future sale of equity
securities may be materially impaired. If the trial judge's award of the shares
is not reversed on appeal, the issuance of such shares would have a significant
negative effect on the market price of the shares.


                                       11
<PAGE>
     In June 1995, the Company filed against Jacskon Morris, the lawyer who was
in charge of drafting and advising it on the Share Exchange Agreement. Mr.
Morris, who had been recommended to the Company by Dr. Friedenberg, is alleged
by the Company to have breached his fiduciary duty to the Company by later
advising Dr. Friedenberg, individually, on how to rescind the Share Exchange
Agreement. Mr. Morris is also charged with negligence in drafting the Share
Exchange Agreement. The Company's lawsuit demands damages in the amount of
$1,000,000. Mr. Morris has counterclaimed as a party to the Share Exchange
Agreement and seeks common shares. No trial date has been set. The Company is
vigorously contesting the Morris Claim.
    

                              SELLING SHAREHOLDERS
   
     The following table sets forth the names of the Selling Shareholders, the
number of Common Shares owned beneficially by each of the Selling Shareholders
as of October 31, 1998, and the number of Common Shares which may be offered for
sale pursuant to the Prospectus. Because the Selling Shareholders may offer all,
some or none of their Common Shares, no definitive estimate as to the number of
Common Shares that will be held by the Selling Shareholders after such offering
can be provided and the following table has been prepared on the assumption that
all Common Shares covered by this Prospectus will be sold.
    
   
     The Company has agreed initially to register 2,143,056 Common Shares for
resale after conversion of the Series "D" Preferred Shares, all of which are
covered by this Prospectus and to register for resale the 107,355 Common Shares
issuable upon exercise of the Warrants.
    
     Unless otherwise indicated, the persons and entities named in the table
have sole voting and sole investment power with respect to all Common Shares
beneficially owned, subject to community property laws where applicable. Except,
as noted below, the Selling Shareholders have not held any position or office,
or had any material relationship with the Company or any of its predecessors or
affiliates within the last three years.

Castle Creek Partners, LLC is the investment advisor to CC Investments, LDC and
consequently may be deemed to have voting control and investment discretion over
the securities held by CC Investments, LDC. Castle Creek Partners, LLC disclaims
beneficial ownership of all securities owned by CC Investments, LDC. Daniel
Asher and John Ziegelman may be deemed to be the beneficial owners of the Common
Stock and Preferred Stock held by CC Investments, LDC. Mr. Asher and Mr.
Ziegetman disclaim such beneficial ownership.


                                     12
<PAGE>
   
(1)  Beneficial ownership is determined in accordance with the rules of the
     Securities and Exchange Commission and generally includes voting or
     investment power with respect to securities and includes any securities
     which the person has the right to acquire within 60 days of December 24,
     1998 through the conversion or exercise of any security or other right.

(2)  Includes 418,612 Common Shares, and 862,222 Common Shares issuable upon
     conversion of the Series "D" Preferred Shares calculated using an assumed
     conversion price of $2.1375 per share (representing 95% of a $2.250 per
     share assumed Market Price) and the stated value of the Series "D"
     Preferred Shares. The Series "D" Preferred Shares were issued pursuant to a
     Securities Purchase Agreement, dated April 24, 1998 (the "Closing Date").
     Each Series "D" Preferred Share has a face amount of $1,000 and converts,
     subject to certain restrictions, into a number of Common Shares equal to
     $1,000 divided by a variable conversion rate equal to the lower of (a) 95%
     of the Market Price and (b) $4.625. Pursuant to the terms of the Series "D"
     Preferred Shares and the Warrants, no holder thereof can convert any
     portion of such Series "D" Preferred Shares or exercise any Warrants if
     such conversion or exercise would increase such holder's beneficial
     ownership of Common Shares to in excess of 4.9%. Absent such limitations at
     the $2.1375 per share conversion price the Series "D" Preferred Shares held
     by CC Investments, LDC would have been convertible into 862,222 Common
     Shares, which, when added to the 418,612 Common Shares received from the
     conversion of 750 Series "D" Preferred Shares and 100,000 shares issuable
     upon exercise of Warrants, would have represented 10.3% of the Common
     Shares. (The ownership limitations may be waived by a holder of Series "D"
     Preferred Shares or Warrants (the "Selling Shareholder") on 90 days
     notice.) The number of Common Shares registered pursuant to the
     Registration Statement on behalf of the Selling Shareholder holding Series
     "D" Preferred Shares and the number of Common Shares offered hereby by such
     holder have been determined by agreement between the Company and such
     Selling Shareholder. Because the number of Common Shares that will
     ultimately be issued upon conversion of the Series "D" Preferred Shares is
     dependent, subject to certain limitations, upon the average of certain
     closing bid prices of the Common Shares prior to conversion, as described
     above, and certain antidilution adjustments, such number of Common Shares
     (and therefore the number of Common Shares to ultimately be offered hereby)
     cannot be determined at this time. Moreover, pursuant to Nasdaq SmallCap
     regulations, the Company may be subject to a limitation that, in the
     absence of shareholder approval, the aggregate number of Common Shares
     issuable to the Selling Shareholders at a discount from market price upon
     conversion of the Series "D" Preferred Shares and exercise of the Warrants
     may not exceed 20% of the outstanding Common Shares. Unless shareholder
     approval is obtained to issue Common Shares to the Selling Shareholders in
     excess of such maximum amount set forth above, none of the Selling
     Shareholders will be entitled to acquire more than its proportionate share
     of such maximum amount. Any Series "D" Preferred Shares which may not be
     converted and any Warrants which may not be exercised because of such
     limitation must be redeemed by the Company
    

(3)  Consists of Warrants to purchase 7,355 Common Shares by Shoreline Pacific
     Institutional Finance in connection with such company's role as Selling
     Agent for the private placement of the Series "D" Preferred Shares in
     April, 1998.

<PAGE>
                              PLAN OF DISTRIBUTION

     The Common Shares will be offered and sold by the Selling Shareholders for
their own accounts. The Company will not receive any proceeds from the sale of
the Common Shares pursuant to this Prospectus. The Company has agreed to pay the
expenses of registration of the Common Shares, including legal and accounting
fees.

     The Common Shares offered hereby may be sold by the Selling Shareholders or
by pledgees, donees, transferees or other successors in interest that receive
such shares as a gift, partnership distribution or other non-sale related
transfer. The Common Shares may be sold from time to time in transactions in the
over-the-counter market, in negotiated transactions, or a combination of such
methods of sale, at fixed prices which may be changed, at market prices
prevailing at the time of sale, at prices related to prevailing market prices or
at negotiated prices. The Selling Shareholders may effect such transaction by
selling the Common Shares to or through broker-dealers, including block trades
in which brokers or dealers will attempt to sell the Common Shares as agent but
may position and resell the block as principal, or in one or more underwritten
offerings on a firm commitment or best efforts basis. Sales of Selling
Shareholders' Common Shares may also be made pursuant to Rule 144 under the
Securities Act, where applicable.

 To the extent required under the Securities Act, the name of any Selling
Shareholder not named herein, the aggregate amount of the Selling Shareholder's
Common Shares being offered, the terms of the offering, the names of any agents,
brokers, dealers or underwriters and any applicable commission with respect to a
particular offer will be set forth in an accompanying Prospectus Supplement. Any
underwriters, dealers, brokers or agents participating in the distribution of
the Common Shares may receive compensation in the form of underwriting
discounts, concessions, commissions or fees from a Selling Shareholder and/or
purchasers of Selling Shareholders' Common Shares, for whom they may act (which
compensation as to a particular broker-dealer might be in excess of customary
commissions).

     From time to time, one or more of the Selling Shareholders may transfer,
pledge, donate or assign such Selling Shareholders' Common Shares to lenders or
others and each of such persons will be deemed to be a "Selling Shareholder" for
purposes of this Prospectus. The number of Selling Shareholders' Common Shares
beneficially owned by those Selling Shareholders who so transfer, pledge, donate
or assign Selling Shareholders' Common Shares will decrease as and when they
take such actions. The plan of distribution for Selling Shareholders' Common
Shares sold hereunder will otherwise remain unchanged, except that the
transferees, pledgees, donees or other successors will be Selling Shareholders
hereunder.

     A Selling Shareholder may enter into hedging transactions with
broker-dealers and the broker-dealers may engage in short sales of the Common
Shares in the course of hedging the positions they assume with such Selling
Shareholder, including, without limitation, in connection with distributions of
the Common Shares by such broker-dealers. In addition, a Selling Shareholder
may, from time to time, sell short the Common Shares of the Company, and in such
instances, this Prospectus may be delivered in connection with such short sales
and the Common Shares offered hereby may be used to cover such short sales. A
Selling Shareholder may also enter into option or other transactions with
broker-dealers that involve the delivery of the Common Shares to the
broker-dealers, who may then resell or otherwise transfer such Common Shares. A
Selling Shareholder may also loan or pledge the Common Shares to a broker-dealer
and the broker-dealer may sell the Common Shares so loaned or upon a default may
sell or otherwise transfer the pledged Common Shares.


                                       14
<PAGE>
     Common Shares to be sold hereunder may be issued upon conversion of the
Series "D" Preferred Shares in accordance with their terms, or in other
transactions with the Company involving the Series "D" Preferred Shares,
including, without limitation, issuance of Common Shares in exchange for Series
"D" Preferred Shares and issuance of Common Shares pursuant to modification of
the terms of the Series "D" Preferred Shares, or in settlement of claims with
respect to rights of holders of Series "D" Preferred Shares.

     In order to comply with the securities laws of certain states, if
applicable, the Common Shares will be sold in such jurisdictions only through
registered or licensed brokers or dealers. In addition, in certain states the
Common Shares may not be sold unless they have been registered or qualified for
sale in the applicable state or an exemption from the registration or
qualification requirement is available and is complied with.

     The Selling Shareholders and any broker-dealer or agents that participate
with the Selling Shareholders in the distribution of the Shares may be deemed to
be "underwriters" within the meaning of Section 2(11) of the Securities Act, and
any commissions received by them and any profit on the resale of the Common
Shares purchased by them may be deemed to be underwriting commissions or
discounts under the Securities Act.


                                  LEGAL MATTERS

     The validity of the securities offered by the Prospectus is being passed
upon for the Company by Joel Pensley, Esq., 276 Fifth Avenue, New York, New York
10023. Joel Pensley is the owner of 5,000 Common Shares and 30,000 Nonstatutory
Options.

     Item 15. Indemnification of Directors and Officers

     The New York Business Corporation Law provides for the indemnification of
the Company's officers, directors and corporate employees and agents under
certain circumstances as follows:

     721 NONEXCLUSIVITY OF STATUTORY PROVISIONS FOR INDEMNIFICATION OF
DIRECTORS
AND OFFICERS.

     The indemnification and advancement of expenses granted pursuant to, or
provided by, this article shall not be deemed exclusive of any other rights to
which a director or officer seeking indemnification or advancement of expenses
may be entitled, whether contained in the certificate of incorporation or the
by-laws or, when authorized by such certificate of incorporation or by-laws, (i)
a resolution of shareholders, (ii) a resolution of directors, or (iii) an
agreement providing for such indemnification, provided that no indemnification
may be made to or on behalf of any director or officer if a judgment or other
final adjudication adverse to the director or officer establishes that his acts
were committed in bad faith or were the result of active and deliberate
dishonesty and were material to the cause of action so adjudicated, or that he
personally gained in fact a financial profit or other advantage to which he was
not legally entitled. Nothing contained in this article shall affect any rights
to indemnification to which corporate personnel other than directors and
officers may be entitled by contract or otherwise under law.

     722 AUTHORIZATION FOR INDEMNIFICATION OF DIRECTORS AND OFFICERS.

(a)  A corporation may indemnify any person, made, or threatened to be made, a
     party to an action or proceeding other than one by or in the right of the
     corporation to procure a judgment in its favor, whether civil or criminal,
     including an action by or in the right of any other corporation of any type
     or kind, domestic or foreign, or any partnership joint venture, trust,
     employee benefit plan or other enterprise, which any director or officer of
     the corporation served in any capacity at the request of the corporation,
     by reason of the fact that he, his testator or intestate, was a director or
     officer of the corporation, or served such other corporation, partnership,
     joint venture, trust, employee benefit plan or other enterprise in any
     capacity, against judgments, fines, amounts paid in settlement and
     reasonable expenses, including attorneys' fees actually and necessarily
     incurred as a result of such action or proceeding, or any appeal therein,
     if such director or officer acted, in good faith, for a purpose which he
     reasonably believed to be in, or, in the case of service for any other
     corporation or any partnership, joint venture, trust, employee benefit plan
     or other enterprise, not opposed to, the best interests of the corporation
     and, in criminal actions or proceedings, in addition, had no reasonable
     cause to believe that his conduct was unlawful.

(b)  The termination of any such civil or criminal action or proceeding by
     judgment, settlement, conviction or upon a plea of nolo contendere, or its
     equivalent, shall not in itself create a presumption that any such director
     or officer did not act, in good faith, for a purpose which he reasonably
     believed to be in, or, in the case of service for any other corporation or
     any partnership, joint venture, trust, employee benefit plan or other
     enterprise, not opposed to, the best interests of the corporation or that
     he had reasonable cause to believe that his conduct was unlawful.

(c)  A corporation may indemnify any person made, or threatened to be made, a
     party to an action by or in the right of the corporation to procure a
     judgment in its favor by mason of the fact that he, his testator or
     intestate, is or was a director or officer of the corporation, or is or was
     seeing at the request of the corporation as a director or officer of any
     other corporation of any type or kind, domestic or foreign, of any
     partnership, joint venture, trust, employee benefit plan or other
     enterprise, against amounts paid in settlement and reasonable expenses,
     including attorneys' fees, actually and necessarily incurred by him in
     connection with the defense or settlement of such action, or in connection
     with an appeal therein if such director or officer acted, in good faith,
     for a purpose which he reasonably believed to be in, or, in the case of
     service for any other corporation or any partnership, joint venture, trust,
     employee benefit plan or other enterprise, not opposed to, the best
     interests of the corporation, except that no indemnification under this
     paragraph shall be made in respect of (1) a threatened action, or a pending
     action which is settled or otherwise disposed of, or (2) any claim issue or
     matter as to which such person shall have been adjudged to be liable to the
     corporation. unless and only to the extent that the court on which the
     action was brought, or, if no action was brought, any court of competent
     jurisdiction, determines upon application that, in view of all the
     circumstances of the case, the person is fairly and reasonably entitled to
     indemnity for such portion of the settlement amount and expenses as the
     court deems proper.



                                       iv
<PAGE>
(d)  For the purpose of this section, a corporation shall be deemed to have
     requested a person to serve an employee benefit plan where the performance
     by such person of his duties to the corporation also imposes duties on, or
     otherwise involves services by, such person to the plan or participants or
     beneficiaries of the plan; excise taxes assessed on a person with respect
     to an employee benefit plan pursuant to applicable law shall be considered
     fines; and action taken or omitted by a person with respect to an employee
     benefit plan in the performance of such person's duties for a purpose
     reasonably believed by such person to be in the interest of the
     participants and beneficiaries of the plan shall be deemed to be for a
     purpose which is not opposed to the best interests of the corporation.

     723 PAYMENT OF INDEMNIFICATION OTHER THAN BY COURT AWARD.

(a)  A person who has been successful, on the merits or otherwise, in the
     defense of a civil or criminal action or proceeding of the character
     described in section 722 shall be entitled to indemnification as authorized
     in such section.

(b)  Except as provided in paragraph (a), any indemnification under section 722
     or otherwise permitted by section 721, unless ordered by a court under
     section 724 (Indemnification of directors and officers by a court), shall
     be made by the corporation, only if authorized in the specific case:

     (1)  By the board acting by a quorum consisting of directors who are not
          parties to such action or proceeding upon a finding that the director
          or officer has met the standard of conduct set forth in section 722 or
          established pursuant to section 721, as the case may be, or,

     (2)  If a quorum under subparagraph (1) is not obtainable or, even if
          obtainable, a quorum of disinterested directors so directs;

          (A)  By the board upon the opinion in writing of independent legal
               counsel that indemnification is proper in the circumstances
               because the applicable standard of conduct set forth in such
               sections has been met by such director or officer, or

          (B)  By the shareholders upon a finding that the director or officer
               has met the applicable standard of conduct set forth in such
               sections.

(c)  Expenses incurred in defending a civil or criminal action or proceeding may
     be paid by the corporation in advance of the final disposition of such
     action or proceeding upon receipt of an undertaking by or on behalf of such
     director or officer to repay such amount as, and to the extent, required by
     paragraph (a) of section 725.

     724 INDEMNIFICATION OF DIRECTORS AND OFFICERS BY A COURT.

(a)  Notwithstanding the failure of a corporation to provide indemnification,
     and despite any contrary resolution of the board or of the shareholders in
     the specific case under section 723 (Payment of indemnification other than
     by court award), indemnification shall be awarded by a court to the extent
     authorized under section 722 (Authorization for indemnification of
     directors and officers) and paragraph (a) of section 723. Application
     therefore may be made, in every case, either:

     (1)  In the civil action or proceeding in which the expenses were incurred
          or the amounts were paid, or

     (2)  To the supreme court in a separate proceeding, in which case the
          application shall set forth the disposition of any previous
          application made to any court for the same or similar relief and also
          reasonable cause for the failure to make application for such relief
          in the action or proceeding in which the expenses were incurred or
          other amounts were paid.

(b)  The application shall be made in such manner and form as may be required by
     the applicable rules of court or, in the absence thereof, by direction of a
     court to which it is made. Such application shall be upon notice to the
     corporation. The court may also direct that notice by given at the expense
     of the corporation to the shareholder and such other person as it may
     designate in such manner as it may require.

(c)  Where indemnification is sought by judicial action, the court may allow a
     person such reasonable expenses, including attorneys' fees, during the
     pendency of the litigation as are necessary in connection with his defense
     therein, if the court shall find that the defendant has by his pleadings or
     during the course of the litigation raised genuine issues of fact or law.

     725 OTHER PROVISIONS AFFECTING INDEMNIFICATION OF DIRECTORS AND
OFFICERS.

(a)  All expenses incurred in defending a civil or criminal action or proceeding
     which are advanced by the corporation under paragraph (c) of section 723
     (Payment of indemnification other than by court award) or allowed by a
     court under paragraph (c) of section 724 (Indemnification of directors and
     officers by a court) shall be repaid in case the person receiving such
     advancement or allowance is ultimately found, under the procedure set forth
     in this article, not to be entitled to indemnification or, where
     indemnification is granted, to the extent the expenses so advanced by the
     corporation or allowed by the court exceed the indemnification to which he
     is entitled.


                                       vi
<PAGE>
(b)  No indemnification, advancement or allowance shall be made under this
     article in any circumstance where it appears:

     (1)  That the indemnification would be inconsistent with the law of the
          jurisdiction of incorporation of a foreign corporation which prohibits
          or otherwise limits such indemnification;

     (2)  That the indemnification would be inconsistent with a provision of the
          certificate of incorporation, a by-law, a resolution of the board or
          of the shareholders, an agreement or other proper corporate action, in
          effect at the time of the accrual of the alleged cause of action
          asserted in the threatened or pending action or proceeding in which
          the expenses were incurred or other amounts were paid, which prohibits
          or otherwise limits indemnification; or

     (3)  If there has been a settlement approved by the court, that the
          indemnification would be inconsistent with any condition with respect
          to indemnification expressly imposed by the court in approving the
          settlement.

(c)  If any expenses or other amounts are paid by way of indemnification,
     otherwise than by court order or action by the shareholders, the
     corporation shall, not later than the next annual meeting of shareholders
     unless such meeting is held within three months from the date of such
     payment, and in any event, within fifteen months from the date of such
     payment, mail to its shareholders of record at the time entitled to vote
     for the election of directors a statement specifying the persons paid, the
     amounts paid, and the nature and status at the time of such payment of the
     litigation or threatened litigation.

(d)  If any action with respect to indemnification of directors and officers is
     taken by way of amendment of the by-laws, resolution of directors, or by
     agreement, then the corporation shall, not later than the next annual
     meeting of shareholders, unless such meeting is held within three months
     from the date of such action, and, in any event, within fifteen months from
     the date of such action, mail to its shareholders of record at the time
     entitled to vote for the election of directors a statement specifying the
     action taken.

(e)  Any notification required to be made pursuant to the foregoing paragraph
     (c) or (d) of this section by any domestic mutual insurer shall be
     satisfied by compliance with the corresponding provisions of section one
     thousand two hundred sixteen of the insurance law.

(f)  The provisions of this article relating to indemnification of directors and
     officers and insurance therefor shall apply to domestic corporations and
     for corporations doing business in this state, except as provided in
     section 1320 (Exemption from certain provisions).

     726 INSURANCE FOR INDEMNIFICATION OF DIRECTORS AND OFFICERS.

a)   Subject to paragraph (b), a corporation shall have power to purchase and
     maintain insurance:

     (1)  To indemnify the corporation for any obligation which it incurs as a
          result of the indemnification of directors and officers under the
          provisions of this article, and

     (2)  To indemnify directors and officers in instances in which they may be
          indemnified by the corporation under the provisions of this article,
          and

     (3)  To indemnify directors and officers in instances in which they may not
          otherwise be indemnified by the corporation under the provisions of
          this article provided the contract of insurance covering such
          directors and officers provides, in a manner acceptable to the
          superintendent of insurance, for a retention amount and for
          coinsurance.

(b)  No insurance under paragraph (a) may provide for any payment, other than
     cost of defense, to or on behalf of any director or officer:

     (1)  if a judgment or other final adjudication adverse to the insured
          director or officer establishes that his acts of active and deliberate
          dishonesty were material to the cause of action so adjudicated, or
          that he personally gained in fact a financial profit or other
          advantage to which he was not legally entitled, or

     (2)  in relation to any risk the insurance of which is prohibited under the
          insurance law of this state.

(c)  Insurance under any or all subparagraphs of paragraph (a) may be included
     in a single contract or supplement thereto. Retrospective rated contracts
     are prohibited.

(d)  The corporation shall, within the time and to the persons provided in
     paragraph (c) of section 725 (Other provisions affecting indemnification of
     directors or officers), mail a statement in respect of any insurance it has
     purchased or renewed under this section, specifying the insurance carrier,
     date of the contract, cost of the insurance, corporate positions insured,
     and a statement explaining all sums, not previously reported in a statement
     to shareholders, paid under any indemnification insurance contract.

(e)  This section is the public policy of this state to spread the risk of
     corporate management, notwithstanding any other general or special law of
     this state or of any other jurisdiction including the federal government.

     Item 17. Undertakings

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

     The undersigned hereby undertakes:

(a)  to file, during any period in which offers or sales are being made, a
     post-effective amendment to this Registration Statement:

     (i)  to include any prospectus required by section 10(a)(3) of the
          Securities Act of 1933;

     (ii) to reflect in the prospectus any facts or events arising after the
          effective date of this Registration Statement (or the most recent
          post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in this Registration Statement; and

     (iii) to include any material information with respect to the plan of
          distribution not previously disclosed in this Registration Statement
          or any material change to such information in this Registration
          Statement;

     Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
information required to be included in a post effective amendment by these
paragraphs is contained in periodic reports filed by the Company pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934 (the
"Exchange Act") that are incorporated by reference in this Registration
Statement.

(b)  that, for the purposes of determining any liability under said Act, each
     such post-effective amendment shall be deemed to be a new registration
     statement relating to the securities offered therein, and the offering of
     such securities at that time shall be deemed to be the initial bona fide
     offering thereof;

(c)  to remove from registration by means of a post-effective amendment any of
     the securities being registered which remain unsold at the termination of
     the offering;

(d)  That, for purposes of determining any liability under the Act, each filing
     of the Company's annual report pursuant to Section 13(a) or 15(d) of the
     Securities Exchange Act of 1934, as amended (the "Exchange Act") (and,
     where applicable, each filing of an employee benefit's plan's annual report
     pursuant to Section 15(d) of the Exchange Act) that is incorporated by
     reference in the Registration Statement shall be deemed to be a new
     registration statement relating to the securities offered herein, and the
     offering of such securities at that time shall be deemed to be the initial
     bona fide offering thereof.

                          Notes to Financial Statements
                                  July 31, 1998

Note A - Basis of Reporting

     The accompanying unaudited financial statements have been prepared in
accordance with generally accepted accounting principles for interim financial
information and with the instructions to Form 10-Q. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, such statements include all adjustments (consisting only of normal
recurring items) which are considered necessary for a fair presentation of
thefinancial position of American Bio Medica Corporation (the "Company") at July
31, 1998, and the results of its operations, and cash flows for the three-month
period then ended. The results of operations for the three-month period ended
July 31, 1998 are not necessarily indicative of the operating results for the
full year. It is suggested that these financial statements be read in
conjunction with the financial statements and related disclosures for the year
ended April 30, 1998 included in the Company's Form 10-KSB.



Note B - Net Income Per Share of Common Stock

     In 1997, the Financial Accounting Standards Board issued
Statement No. 128, "Earnings Per Share".  Statement No. 128 replaced
the calculation of primary and fully  diluted  earnings  per share
with basic and diluted  earnings  per share. Unlike primary earnings
per share, basic earnings per share exclude any dilutive effects of
options, warrants, and convertible securities.  Dilutive earnings per
share is very similar to the  previously  reported  fully  diluted
earnings per share. The Company adopted Statement No. 128 and has
retroactively  applied the effects thereof for all periods
presented.  The impact on the per share amounts previously reported
was not significant.
     When preferred stock is convertible to common stock at a conversion rate
that is the lower of a rate fixed at issuance or a fixed discount from the
common stock market price at the time of conversion, the discounted amount is an
assured incremental yield, the "beneficial conversion feature", to the preferred
shareholders and should be accounted for as an embedded dividend to preferred
shareholders. As such, the loss per common share was adjusted for this feature.

Note C - Restatement of Prior Year Quarterly Statements of Operations

On April 30, 1998 the company recorded adjustments relating to book sale
revenues and certain non-cash employee and consulting compensation charges.
Based upon these and other minor adjustments, prior-year's quarterly information
has been revised as follows:

Note D - Litigation

      In February 1994, Robert Friedenberg, as former owner of the two medical
technology companies, MDI and Gendex, acquired by the Company, in the name of
these corporations, filed for a declaratory judgement that a Share Exchange
Agreement had been rescinded. In order to make a claim for damages, the Company
filed a third-party claim against Dr. Friedenberg for breach of the Share
Exchange Agreement and fraud. In November 1995, after a trial, the court denied
Dr. Friedenberg's request for a declaration of rescission and allowed the
Company's third-party claim to proceed to trial. In September, 1996, Dr.
Friedenberg died.

                                       7
<PAGE>
      The Company's third-party claim was decided by a jury on May 5, 1997. The
verdict determined that Dr. Friedenberg breached the Share Exchange Agreement,
when he failed to deliver drug screening know how technology to the Company. The
jury also found in favor of the Company on two of the three fraud claims against
Friedenberg and awarded the Company approximately $321,000 in damages.
Friedenberg's estate, just prior to the jury trial, filed a supplemental claim
for the shares of the Company's stock which he would have received under the
Share Exchange Agreement. The trial judge took this supplemental claim under
advisement. The trial judge, on July 17, 1998, ruled that the estate of Dr.
Friedenberg is entitled to 5,907,154 common shares of the Company. The Company
has filed an appeal. Management of the Company in consultation with counsel is
of the opinion that the trial judge's award of the shares to Dr. Friedenberg's
estate will be reversed on appeal.

      Pending the resolution of the Company's appeal, the trial judge has
ordered that the shares be issued in the name of Dr. Friedenberg's wife and
placed in escrow or that the Company post a bond. The Company has applied for a
stay of this order. If the trial judge's order is not stayed, the issuance of
such shares or the posting of the required bond could have a significant
negative effect on the market price of the shares. Pending the resolution of the
Company's appeal of the trial judge's award of the shares to Dr. Friedenberg's
estate, the Company's ability to raise capital through the future sale of equity
securities may be materially impaired. If the trial judge's award of the shares
is not reversed on appeal, the issuance of such shares would have a significant
negative effect on the market price of the shares.

      In June 1995, the Company filed against Jacskon Morris, the
lawyer who was in charge of drafting and advising it on the Share
Exchange Agreement. Mr. Morris, who had been recommended to the
Company by Dr. Friedenberg, is alleged by the Company to have breached
his fiduciary duty to the Company by later advising Dr. Friedenberg,
individually, on how to rescind the Share Exchange Agreement. Mr.
Morris is also charged with negligence in drafting the Share Exchange
Agreement.  The Company's lawsuit demands damages in the amount of
$1,000,000. Mr. Morris has counterclaimed as a party to the Share
Exchange Agreement and seeks common shares.  No trial date has been
set. The Company is vigorously contesting the Morris Claim.

         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS
                for the three months ended July 31, 1998 and 1997


     The following discussion of the company's financial condition and results
of operations should be read in conjunction with the Financial Statements and
Notes thereto appearing elsewhere in this document.

     Statements in this "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and elsewhere in this document as well as
statements made in press releases and oral statements that may be made by the
Company or by officers, directors or employees of the Company acting on the
Company's behalf that are not statements of historical or current fact
constitute "forward looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995. Such forward-looking statements
involve known and unknown risks, uncertainties and other unknown factors that
could cause the actual results of the Company to be materially different from
the historical results or from any future results expressed or implied by such
forward-looking statements. In addition to statements which explicitly describe
such risks and uncertainties, readers are urged to consider statements labeled
with the terms "believes", "belief", "expects", "intends", "anticipates" or
"plans" to be uncertain forward-looking. The forward looking statements
contained herein are also subject generally to other risks and uncertainties
that are described from time to time in the Company's reports and registration
statements filed with the Securities and Exchange Commission.


     Results of operations for the three months ended July 31, 1998 as compared
to the three months ended July 31, 1997 as amended.
- -------------------------------------------------------------------------------
     During the current quarter, the Company continued its extensive program to
market and distribute its primary product, the Rapid Drug Test kit. As a result,
revenues from the sale of the test kits were $1,165,000 for the three months
ended July 31, 1998 as compared to $635,000 for the three months ended July 31,
1997, representing an increase of $530,000 or 83.5% over the preceding year.
Cost of goods sold for the three months ended July 31, 1998 was $487,000 or
41.8% of drug test revenues as compared to $345,000 or 54.3% of drug test
revenues for the three months ended July 31, 1997. To further reduce this cost,
the Company has undertaken to improve its manufacturing processes and expects
further savings throughout the year.

     Revenues from book sales were $143,000 for the three months ended July 31,
1998 as compared to $31,000 for the three months ended July 31, 1997
representing an increase of $112,000 or 361.3%. It is anticipated that with
continuing strong sales in the drug test market, book sales as a percent of
overall revenue will continue to decline. Cost of goods sold for the year ended
July 31, 1998 was $27,000 (18.9% of book sales) as compared to $24,000 (77.4% of
book sales) for the three months ended July 31, 1997.

     General and administrative costs for the three months ended July 31, 1998
were $1,031,000, an increase of 130.1% over expenses of $448,000 for the three
months ended July 31,1997. These increased general and administrative costs are
undertaken to create the infrastructure necessary to meet the Company's
worldwide drug test marketing and production goals. As an outgrowth of
increasing drug test sales the Company expects general and administrative costs
to continue to increase but at a slower rate. As a percent of sales, this cost
increased 11.5% during the current year but is expected to decrease with
anticipated sales growth.

     Depreciation and amortization was $18,000 and $25,000 for the three months
ended July 31, 1998 and 1997 respectively.

                                       9
<PAGE>
     Research and development expense amounted to $50,000 for the three months
ended July 31 1998. This represents management's continued emphasis on the
development of both new products and improved methods to reduce the costs of the
drug testing delivery system.

     Liquidity and capital resources as of the end of the three months ended
July 31, 1998.
- -------------------------------------------------------------------------------
     The Company's cash and cash equivalents amounted to $2,089,000 for the
three months ended July 31, 1998 representing a decrease of $1,150,000 or 35.5%
over $3,239,000 for the year ended April 30, 1998. Working capital decreased
$434,000 or 9.7% over $4,480,000 recorded for the year ended April 30, 1998.

     The decrease in working capital resulted from the following operating
increases in accounts receivable, inventories, prepaid expenses, accounts
payable and results of operations.

     As a result of strong first quarter sales of drug test kits, accounts
receivable increased $297,000 or 41.7% to $1,009,000 for the three months ended
July 31, 1998 compared to $712,000 for the year ended April 30, 1998.


     Inventories rose 17.8% to $1,167,000 for the three months ended July 31,
1998 or $571,000 above $596,000 reported as of the three months ended July 31,
1997.

     Prepaid expenses rose $88,000 to $112,000 for the three months ended July
31, 1998 related to expenditures for prepaid insurance, advertising and
commissions.

     Account payable and accrued expenses decreased $155,000 for the three
months ended July 31, 1998.

     Net (loss) from operations amounted to $(276,000) for the three months
ended July 31, 1998 due to increases in selling, general and administrative
expenditures related to the expansion of the Company's infrastructure .

     The Company's primary short-term needs are to increase its manufacturing
capabilities, increase inventory levels and continue to support its research and
development programs. The Company currently plans to expend approximately $2.0
million for the expansion and development of its manufacturing facilities in
addition to its marketing and general administrative programs.

     The Company expects its capital requirements to increase over the next
several years as it expands its research and development efforts, new product
development, sales and administration infrastructure, manufacturing capabilities
and facilities. The Company's future liquidity and capital funding requirements
will depend on numerous factors, including the extent to which the Company's
products under development are successfully developed and gain market
acceptance, the timing of regulatory actions regarding the Company's potential
products, the costs and timing of expansion of sales, marketing and
manufacturing activities, facilities expansion needs, procurement and
enforcement of patents important to the Company's business, results of clinical
investigations and competition.

     The Company believes that its available cash and cash from operations will
be sufficient to satisfy its funding needs for at least the next 12 months.
Thereafter, if cash generated from operations is insufficient to satisfy the
Company's working capital and capital expenditure requirements, the Company may
be required to sell additional equity or debt securities or obtain additional
credit facilities. There can be no assurance that such financing, if required,
will be available on satisfactory terms, if at all.

                                OTHER INFORMATION

 Item 1. Legal Proceedings.

     In February 1994, Robert Freidenberg, as owner of the two medical
technology companies, MDI and Gendex, acquired by the Company, in the name of
these corporations, filed suit to have a Share Exchange Agreement rescinded on
the grounds of breach of contract. In order to preserve a claim for damages, the
Company filed a third-party claim against Dr. Freidenberg, for breach of the
Share Exchange Agreement. In November 1995, after a trial, the court dismissed
Dr. Friedenberg's lawsuit and allowed the Company's third-party claim to proceed
to trial.In September, 1996, Dr. Friedenberg died. A pretrail hearing was held
in December 1996 which set a trial date of April 28, 1997.

     That trial was decided by a jury on May 5, 1997. The verdict determined
that Dr. Friedenberg breached various contracts, including the Share Exchange
Agreement, when he failed to deliver technology to the Company. The jury also
found in favor of the Company on two of the three fraud claims against Dr.
Friedenberg and awarded the Company approximately $321,000 in damages. Dr.
Friedenberg's estate, just prior to the jury trial, filed a supplemental claim
for the shares of the Company's stock which he would have received under the
Share Exchange Agreement which the trial judge took under advisement. The trial
judge, on July 17, 1998 ruled that the estate of Dr. Friedenberg is entitled to
5,907,154 common shares of the Company. The Company has filed an appeal.
Management of the Company in consultation with counsel is of the opinion that
the trial judge's award of the shares to Dr. Friedenberg's estate will be
reversed on appeal.

     In June 1995, the Company filed a lawsuit against Mr. Morris, Dr.
Friedenberg's counsel, for the breach of attorney-client relationship and his
fiduciary duty and negligence in representing the Company in matters relating to
Dr. Friedenberg and in the preparation of the Share Exchange Agreement. The
Company's lawsuit demands damages in the amount of $1,000,000. Mr. Morris has
counterclaimed for common shares. No trial date has been set. The Company is
vigorously contesting the Morris claim.

Item 2. Changes in Securities

     None.

Item 3. Defaults upon Senior Securities

     None.

Item 4. Submission of Matters to a Vote of Security-Holders

Notes to Financial Statements
                                October 31, 1998

Note A - Basis of Reporting

     The accompanying unaudited financial statements have been prepared in
accordance with generally accepted accounting principles for interim financial
information and with the instructions to Form 10-Q. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, such statements include all adjustments (consisting only of normal
recurring items) which are considered necessary for a fair presentation of the
financial position of American Bio Medica Corporation (the "Company")at October
31, 1998, and the results of its operations, and cash flows for the six-month
period then ended. The results of operations for the six-month period ended
October 31, 1998 are not necessarily indicative of the operating results for the
full year. It is suggested that these financial statements be read in
conjunction with the financial statements and related disclosures for the year
ended April 30, 1998 included in the Company's Form 10-KSB.


Note B - Net Income Per Share of Common Stock

     In 1997, the Financial Accounting Standards Board issued Statement No. 128,
"Earnings Per Share". Statement No. 128 replaced the calculation of primary and
fully diluted earnings per share with basic and diluted earnings per share.
Unlike primary earnings per share, basic earnings per share exclude any dilutive
effects of options, warrants, and convertible securities. Dilutive earnings per
share is very similar to the previously reported fully diluted earnings per
share. The Company adopted Statement No. 128 and has retroactively applied the
effects thereof for all periods presented. The impact on the per share amounts
previously reported was not significant.

     When preferred stock is convertible to common stock at a conversion rate
that is the lower of a rate fixed at issuance or a fixed discount from the
common stock market price at the time of conversion, the discounted amount is an
assured incremental yield, the "beneficial conversion feature", to the preferred
shareholders and should be accounted for as an embedded dividend to preferred
shareholders. As such, the loss per common share was adjusted for this feature.

<PAGE>
Note C - Restatement of Prior Year Quarterly Statements of Operations

On April 30, 1998 the company recorded adjustments relating to book sale
revenues and certain non-cash employee and consulting compensation charges.
Based upon these and other minor adjustments, prior-year's quarterly information
has been revised as follows:

 Note D - Litigation

      In February 1994, Robert Friedenberg, as former owner of the two medical
technology companies, MDI and Gendex, acquired by the Company, in the name of
these corporations, filed for a declaratory judgement that a Share Exchange
Agreement had been rescinded. In order to make a claim for damages, the Company
filed a third-party claim against Dr. Friedenberg for breach of the Share
Exchange Agreement and fraud. In November 1995, after a trial, the court denied
Dr. Friedenberg's request for a declaration of rescission and allowed the
Company's third-party claim to proceed to trial. In September, 1996, Dr.
Friedenberg died.

      The Company's third-party claim was decided by a jury on May 5, 1997. The
verdict determined that Dr. Friedenberg breached the Share Exchange Agreement,
when he failed to deliver drug screening know how technology to the Company. The
jury also found in favor of the Company on two of the three fraud claims against
Friedenberg and awarded the Company approximately $321,000 in damages.
Friedenberg's estate, just prior to the jury trial, filed a supplemental claim
for the shares of the Company's stock which he would have received under the
Share Exchange Agreement. The trial judge took this supplemental claim under
advisement. The trial judge, on July 17, 1998, ruled that the estate of Dr.
Friedenberg is entitled to 5,907,154 common shares of the Company. The Company
has filed an appeal. Management of the Company in consultation with counsel is
of the opinion that the trial judge's award of the shares to Dr.
Friedenberg's estate will be reversed on appeal.

<PAGE>
      Pending the resolution of the Company's appeal, the trial judge has
ordered that the shares be issued in the name of Dr. Friedenberg's wife and
placed in escrow or that the Company post a bond. The Company has applied for a
stay of this order. If the trial judge's order is not stayed, the issuance of
such shares or the posting of the required bond could have a significant
negative effect on the market price of the shares. Pending the resolution of the
Company's appeal of the trial judge's award of the shares to Dr. Friedenberg's
estate, the Company's ability to raise capital through the future sale of equity
securities may be materially impaired. If the trial judge's award of the shares
is not reversed on appeal, the issuance of such shares would have a significant
negative effect on the market price of the shares.

      In June 1995, the Company filed against Jacskon Morris, the lawyer
who was in charge of drafting and advising it on the Share Exchange
Agreement. Mr. Morris, who had been recommended to the Company by Dr.
Friedenberg, is alleged by the Company to have breached his fiduciary duty
to the Company by later advising Dr. Friedenberg, individually, on how to
rescind the Share Exchange Agreement. Mr. Morris is also charged with
negligence in drafting the Share Exchange Agreement.  The Company's
lawsuit demands damages in the amount of $1,000,000. Mr. Morris has
counterclaimed as a party to the Share Exchange Agreement and seeks common
shares.  No trial date has been set. The Company is vigorously contesting
the Morris Claim.



 Item 2. Management's Discussion and Analysis or Plan of Operation

         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS
               for the six months ended October 31, 1998 and 1997


     The following discussion of the Company's financial condition and results
of operations should be read in conjunction with the Financial Statements and
Notes thereto appearing elsewhere in this document.

     Statements in this "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and elsewhere in this document as well as
statements made in press releases and oral statements that may be made by the
Company or by officers, directors or employees of the Company acting on the
Company's behalf that are not statements of historical or current fact
constitute "forward looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995. Such forward-looking statements
involve known and unknown risks, uncertainties and other unknown factors that
could cause the actual results of the Company to be materially different from
the historical results or from any future results expressed or implied by such
forward-looking statements. In addition to statements which explicitly describe
such risks and uncertainties, readers are urged to consider statements labeled
with the terms "believes", "belief", "expects", "intends", "anticipates" or
"plans" to be uncertain forward-looking. The forward looking statements
contained herein are also subject generally to other risks and uncertainties
that are described from time to time in the Company's reports and registration
statements filed with the Securities and Exchange Commission.

Year 2000 Issues

The Company has completed its assessment of Year 2000 compliance with respect to
its products that are currently being sold to customers and has concluded that
all significant products are compliant. With respect to third parties, the
Company is in the process of identifying and contacting its significant
suppliers and will shortly begin to contact its major customers to determine the
extent to which the Company may be vulnerable to such third parties' failure to
address their own year 2000 issues. As a result, the Company's assessment will
be substantially dependent on information provided by third parties. The Company
expects to materially complete this assessment process by the end of fiscal
1999. Based upon the Company's current estimates, additional out-of-pocket costs
associated with its Year 2000 compliance are expected to be immaterial. Such
costs do not include internal management time, which is not expected to be
material to the Company's results of operations or financial condition.

<PAGE>
     Results of operations for the six months ended October 31, 1998 as compared
to the six months ended October 31, 1997 as amended.
- --------------------------------------------------------------------------------
      During the six months ended October 31, 1998, the Company continued its
extensive program to market and distribute its primary product, the Rapid Drug
Test kit. As a result, revenues from the sale of the test kits were $2,732,000
for the six months ended October 31, 1998 as compared to $937,000 for the six
months ended October 31, 1997 (as adjusted, see Note C to Notes to Financial
Statements), representing an increase of $1,795,000 or 191.6% over the preceding
year. Cost of goods sold for the six months ended October 31, 1998 was
$1,170,000 or 42.9% of drug test revenues as compared to $440,000 or 47.0% of
drug test revenues for the six months ended October 31, 1997. To further reduce
this cost, the Company has undertaken to improve its manufacturing processes and
expects further savings throughout the year.

      Revenues from book sales were $349,000 for the six months ended October
31, 1998 as compared to $88,000 for the six months ended October 31, 1997
representing an increase of $261,000 or 296.6%. It is anticipated that with
continuing strong sales in the drug test market, book sales as a percent of
overall revenue will continue to decline. Cost of goods sold for the six months
ended October 31, 1998 was $66,000 (19.0% of book sales)as compared to $54,000
(61.4% of book sales)for the six months ended October 31, 1997.

      General and administrative costs for the six months ended October 31, 1998
were $1,984,000, an increase of 99.2% over expenses of $996,000 for the six
months ended October 31, 1997. These increased general and administrative costs
were undertaken to create the infrastructure necessary to meet the Company's
worldwide drug test marketing and production goals. As an outgrowth of
increasing drug test sales the Company expects general and administrative costs
to continue to increase but at a slower rate. As a percent of sales, this cost
decreased 32.8% during the current year and is expected to continue it's
decrease with anticipated sales growth.

      Depreciation and amortization was $43,000 and $51,000 for the six months
ended October 31, 1998 and 1997 respectively.

      Research and development expense amounted to $103,000 for the six months
ended October 31, 1998. This represents management's continued emphasis on the
development of both new products and improved methods to reduce the
costs of the drug testing delivery system.

      Net (loss) from operations amounted to $(268,000) for the six months ended
October 31, 1998 due to increases in selling, general and administrative
expenditures related to the expansion of the company's infrastructure.

Results of operations for the three months ended October 31, 1998 as compared to
the three months ended October 31, 1997 as amended.
- --------------------------------------------------------------------------------

      Revenues from the sale of the test kits were $1,567,000 for the three
months ended October 31, 1998 as compared to $301,000 for the three months ended
October 31, 1997 (as adjusted, see Note C to Notes to Financial Statements),
representing an increase of $1,266,000 or 420.6% over the preceding year. Cost
of goods sold for the three months ended October 31, 1998 amounted to $683,000
or 43.6% of drug test revenues as compared to $94,000 or 31.2% of drug test
revenues for the three months ended October 31, 1997.

      Revenues from book sales were $206,000 for the three months ended October
31, 1998 as compared to $58,000 for the three months ended October 31, 1997
representing an increase of $148,000 or 255.2%. Cost of goods sold for the three
months ended October 31, 1998 amounted to $39,000 (18.9% of book sales) as
compared to $30,000 (51.7% of book sales) for the three months ended October 31,
1997.

      General and administrative costs for the three months ended October 31,
1998 Amounted to $953,000, an increase of 73.9% over expenses of $548,000 for
the three months ended October 31, 1997. As a percent of sales, this cost
decreased 98.8% during the current year and is expected to continue it's
decrease with anticipated sales growth.

<PAGE>
      Depreciation and amortization was $25,000 and $26,000 for the three months
ended October 31, 1998 and 1997 respectively.

      Research and development expense amounted to $52,000 for the three months
ended October 31, 1998, continuing management's emphasis on the development of
both new products and improved methods of production.

      Net income from operations amounted to $9,000 for the three months ended
October 31, 1998 as compared to a net (loss) of $(356,000) for the three months
ended October 31, 1997.

     Liquidity and capital resources as of the end of the six months ended
October 31, 1998.
- --------------------------------------------------------------------------------
      The Company's cash and cash equivalents amounted to $1,597,000 for the six
months ended October 31, 1998 representing a decrease of $1,642,000 or 50.7%
over $3,239,000 for the year ended April 30, 1998. Working capital decreased
$467,000 or 10.4% over $4,480,000 recorded for the year ended April 30, 1998.

      The decrease in working capital resulted from an increase in accounts
payable offset by increases in accounts receivable, inventories, and prepaid
expenses.

      As a result of strong six month sales of drug test kits, accounts
receivable increased $716,000 or 100.6% to $1,428,000 for the six months ended
October 31, 1998 compared to $712,000 for the year ended April 30, 1998.


      Due to increased sales and to obtain favorable prices on bulk purchases,
inventories rose 79.4% to $1,778,000 for the six months ended October 31, 1998
or $787,000 above $991,000 reported as of the six months ended October 31,1997.

      Prepaid expenses primarily for future trade shows and conferences rose
$360,000 to $384,000 for the six months ended October 31, 1998.

      Accounts payable and accrued expenses increased $688,000 for the six
months ended October 31, 1998 due primarily to increased inventory requirements.

      The Company's primary short-term needs are to increase its manufacturing
capabilities, increase inventory levels and continue to support its research and
development programs. The Company currently plans to expend approximately $2.0
million for the expansion and development of its manufacturing facilities in
addition to its marketing and general administrative programs.

      The Company expects its capital requirements to increase over the next
several years as it expands its research and development efforts, new product
development, sales and administration infrastructure, manufacturing capabilities
and facilities. The Company's future liquidity and capital funding requirements
will depend on numerous factors, including the extent to which the Company's
products under development are successfully developed and gain market
acceptance, the timing of regulatory actions regarding the Company's potential
products, the costs and timing of expansion of sales, marketing and
manufacturing activities, facilities expansion needs, procurement and
enforcement of patents important to the Company's business, results of clinical
investigations and competition.

      The Company believes that its available cash and cash from operations will
be sufficient to satisfy its funding needs for at least the next 12 months.
Thereafter, if cash generated from operations is insufficient to satisfy the
Company's working capital and capital expenditure requirements, the Company may
be required to sell additional equity or debt securities or obtain additional
credit facilities. There can be no assurance that such financing, if required,
will be available on satisfactory terms, if at all.

                                OTHER INFORMATION

 Item 1. Legal Proceedings.

     In February 1994, Robert Freidenberg, as owner of the two medical
technology companies, MDI and Gendex, acquired by the Company, in the name of
these corporations, filed suit to have a Share Exchange Agreement rescinded on
the grounds of breach of contract. In order to preserve a claim for damages, the
Company filed a third-party claim against Dr. Freidenberg, for breach of the
Share Exchange Agreement. In November 1995, after a trial, the court dismissed
Dr. Friedenberg's lawsuit and allowed the Company's third-party claim to proceed
to trial. In September, 1996, Dr. Friedenberg died. A pretrial hearing was held
in December 1996 which set a trial date of April 28, 1997.

     That trial was decided by a jury on May 5, 1997. The verdict determined
that Dr. Friedenberg breached various contracts, including the Share Exchange
Agreement, when he failed to deliver technology to the Company. The jury also
found in favor of the Company on two of the three fraud claims against Dr.
Friedenberg and awarded the Company approximately $321,000 in damages. Dr.
Friedenberg's estate, just prior to the jury trial, filed a supplemental claim
for the shares of the Company's stock which he would have received under the
Share Exchange Agreement which the trial judge took under advisement. The trial
judge, on July 17, 1998 ruled that the estate of Dr. Friedenberg is entitled to
5,907,154 common shares of the Company. The Company has filed an appeal.
Management of the Company in consultation with counsel is of the opinion that
the trial judge's award of the shares to Dr. Friedenberg's estate will be
reversed on appeal.

      In June 1995, the Company filed a lawsuit against Mr. Morris, Dr.
Friedenberg's counsel, for the breach of attorney-client relationship and his
fiduciary duty and negligence in representing the Company in matters relating to
Dr. Friedenberg and in the preparation of the Share Exchange Agreement. The
Company's lawsuit demands damages in the amount of $1,000,000. Mr. Morris has
counterclaimed for common shares. No trial date has been set. The Company is
vigorously contesting the Morris claim.

Item 2. Changes in Securities

     None.

Item 3. Defaults upon Senior Securities

EXHIBIT D -  Addition to Item 6. Management's Discussion and Analysis or Plan of
             Operation

Add as first paragraph below:

"RESULTS OF OPERATIONS FOR THE YEAR ENDED APRIL 30, 1998 AS COMPARED TO THE YEAR
ENDED APRIL 30, 1997"


In April 1998 our company's new auditors recommended that Book Revenues along
with Non-cash Compensation be accounted for in a manner different than had
previously been reported. By acceding to their recommendations and considering
the significant amounts involved, our fourth quarter results appeared lopsided
when compared to our prior quarters. Had these and other lesser adjustments been
recorded in the affected periods, the quarterly results described in Notes to
Financial Statements - Note M would have been reported.
