                                   PROSPECTUS

                         AMERICAN BIO MEDICA CORPORATION
                         4,227,420 SHARES COMMON SHARES

         In this prospectus, "ABMC", "we", "us" and "our" refer to American Bio
Medica Corporation.

         This is an offering of: (a) up to 4,227,420 common shares, par value
$0.01 a share, of American Bio Medica Corporation, of which 2,549,000 are common
shares of ABMC and 1,678,420 are common shares issuable upon the exercise of
common share purchase warrants and (b) up to 1,274,500 common share purchase
warrants. All of these securities are being offered by the selling shareholders.
On August 22, 2001, in a private placement exempt from registration under the
Securities Act of 1933, as amended, selling shareholders acquired (a) 2,549,000
common shares for a purchase price of $1.00 per share, and (b) 1,274,500
warrants ("Investor Warrants") to purchase one common share at an exercise price
of $1.05 per share and 203,920 warrants ("Placement Agent Warrants") to purchase
one common share at an exercise price of $1.20 per share, exercisable during a
54 month period beginning on February 22, 2002. The Investor Warrants and
Placement Agent Warrants together shall be referred to as the "Private Placement
Warrants". In addition, selling shareholders acquired 200,000 warrants to
purchase one common share at an exercise price of $1.50 per share pursuant to a
financial advisory agreement filed as an exhibit to our 10-KSB for the fiscal
year ending April 30, 2001 ("Brean Murray Warrants"). We are registering the
selling shareholders' resale of these securities pursuant to Registration Rights
Agreements between the selling shareholders and us. The registration of the
common shares, the Investor Warrants and the common shares issuable upon the
exercise of the Placement Agent Warrants and Brean Murray Warrants does not
necessarily mean that any of them will be offered or sold by the selling
shareholders. The securities may be sold directly by the selling shareholders or
through brokers, dealers or agents in private or market transactions. In
connection with any sales, the selling shareholders and any brokers, dealers or
agents participating in such sales may be deemed to be "underwriters" within the
meaning of the Securities Act. See "Selling Shareholders" and "Plan of
Distribution."

         The last reported sale price of the common shares, which are listed on
The Nasdaq SmallCap Market under the symbol "ABMC," was $1.00 per share on
August 22, 2001. Our headquarters are located at 122 Smith Road, Kinderhook, New
York 12106. Our telephone number is (800) 227-1243.

            CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

         Some of the statements in this Prospectus are forward-looking
statements. In addition, we may make forward-looking statements in future
filings with the Securities and Exchange Commission and in written materials,
press releases and oral statements issued by us or on our behalf.
Forward-looking statements include statements regarding the intent, belief or
current expectations of us or our officers, including statements preceded by,
followed by or including forward-looking terminology such as "may," "will,"
"should," "believe," "expect," "anticipate," "estimate," "continue," "predict"
or similar expressions, with respect to various matters.

         It is important to note that our actual results could differ materially
from those anticipated from the forward-looking statements depending on various
important factors. These important factors include our history of losses and
ability to continue as a going concern, the uncertainty of acceptance of current
and new products in our markets, competition in our markets, our dependence on
our distributors and the other factors discussed in "Risk Factors" beginning on
page 5.

         All forward-looking statements in this Prospectus are based on
information available to us on the date of this Prospectus. We do not undertake
to update any forward-looking statements that may be made by us or on our behalf
in this Prospectus or otherwise. In addition, please note that matters set forth
under the caption "Risk Factors" constitute cautionary statements identifying
important factors with respect to the forward-looking statements, including
certain risks and uncertainties that could cause actual results to differ
materially from those in such forward-looking statements.

                                   THE COMPANY

         We develop, manufacture and market biomedical technologies and products
intended for the immediate, onsite screening for drugs of abuse. Our Rapid Drug
Screen(TM) and Rapid One(TM) are urine-based kits that are easy to use,
cost-effective, highly accurate and reliable tests for the presence of drugs of
abuse in individuals. We own several patents that are used in the Rapid Drug
Screen.

         We produce several versions of a drugs of abuse screening test, under
the name Rapid Drug Screen. The Rapid Drug Screen is a one-step test that allows
a small urine sample to be tested simultaneously for the presence or absence of
up to ten drugs of abuse (cocaine, THC (marijuana), opiates, amphetamine, PCP,
benzodiazepines, methamphetamine, barbiturates, tricyclic antidepressants and
methadone).

         The competitively priced test is self-contained. This eliminates
exposure of the test administrator to the urine sample. We believe that the
Rapid Drug Screen product is easier to use than other competitive products
because it requires no mixing of reagents, pipetting or manipulation of the
test. Controlled tests conducted by an independent laboratory compared the Rapid
Drug Screen with results produced by EMIT II, a standard laboratory test, and
found greater than 99% correlation of results.


                                       3


         Our tests require marketing clearance from the Food and Drug
Administration, or FDA. Our most recent 510k marketing clearance received from
the FDA was for the nine panel test. As a result of the FDA's approval of all
nine drug tests manufactured by us, we can offer a variety of test combinations
to meet customer requirements. Included in our product offerings are nine single
tests called Rapid One, each of which detects one drug of abuse (cocaine, THC,
opiates, amphetamine, PCP, benzodiazepines, methamphetamines, barbiturates and
tricyclic antidepressants). We also have developed a methadone test that we
intend to submit to the FDA for marketing clearance.

         In January 2000, we licensed the exclusive rights to distribute and
market a patented residue and/or trace drug detection system in select markets
in North and South America for a period of five years. We utilize the trademark
"Drug Detector" for this product. The Drug Detector(TM) tests surfaces for the
presence or absence of residue from marijuana, cocaine, heroin or
methamphetamines without the need for urine, hair or saliva samples.

         Our headquarters are located at 122 Smith Road, Kinderhook, New York
12106. Our telephone number is 800-227-1243.

                                  RISK FACTORS

         An investment in our common shares or common share purchase warrants
involves a high degree of risk. You should carefully consider the specific
factors listed below, together with the cautionary statement under the caption
"Cautionary Statement Regarding Forward Looking Statements" and the other
information included in this Prospectus, before purchasing our common shares.
The risks described below are not the only ones that we face. Additional risks
that are not yet known to us or that we currently think are immaterial could
also impair our business, operating results or financial condition. If any of
the following risks actually occur, our business, financial condition or results
of operations could be adversely affected. In such case, the trading price of
our common shares could decline, and you may lose all or part of your
investment.

WE HAVE A LIMITED OPERATING HISTORY, WHICH MAY MAKE IT DIFFICULT TO ACCURATELY
FORECAST OUR FUTURE REVENUES AND OTHER OPERATING RESULTS.

         We began selling our products in 1996. As a result, we have only a
limited operating history upon which you may evaluate our business and
prospects. Our limited operating history may make it difficult or impossible for
analysts or investors to accurately forecast regarding our future revenues and
other operating results and the price of our common stock could decline
substantially.

WE HAVE INCURRED NET LOSSES SINCE WE WERE FORMED.

         Since inception in 1992, we have incurred net losses. As of April 30,
2001, we had an accumulated deficit of $13.5 million. We expect to continue to
make substantial expenditures for sales and marketing, product development and
other purposes. Our ability to achieve and maintain profitability in the future
will primarily depend on our ability to increase sales of our products, reduce
production and other costs and successfully introduce new and enhanced versions
of our existing products into the marketplace. We cannot assure you that we will
be able to increase our revenues at a rate that equals or exceeds expenditures.
Our failure to do so will result in our incurring additional losses.


                                       4


WE DEPEND ON DISTRIBUTORS FOR A MAJORITY OF OUR SALES AND THE LOSS OF, OR
REDUCTION IN SALES BY, OUR CURRENT DISTRIBUTORS COULD SIGNIFICANTLY HARM OUR
BUSINESS.

         We derive a substantial portion of our revenues, and expect to continue
to derive a substantial portion of our revenues in the near future, from sales
by our distributors. During fiscal 2001, approximately 74% of our sales were
made to distributors. Unless and until we diversify and expand our sales force,
our success will depend significantly upon the future sales by our distributors.
The loss of or inability to replace any one or more of these distributors,
significant changes in their product requirements, delays of significant orders
or the occurrence of any sales fluctuations of our products could reduce our
revenues.

WE ONLY OFFER A LIMITED NUMBER OF PRODUCTS AND THE FAILURE OF ANY ONE OF THEM TO
ACHIEVE WIDESPREAD MARKET ACCEPTANCE WOULD SIGNIFICANTLY HARM OUR RESULTS OF
OPERATION.

         We derive substantially all of our revenues from sales of a limited
number of drug testing products. The failure of any of our product offerings to
achieve and maintain a meaningful level of market penetration and customer
satisfaction would harm our revenues.

         In addition, we only began selling our products in 1996, and cannot yet
predict whether they will gain widespread market acceptance. Achieving market
acceptance for our 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 their test kits.
Our Drug Detector has just recently been introduced into the over-the-counter
market. We have no history upon which to base market or customer acceptance of
the product. Introduction of the Drug Detector has required, and may continue to
require, substantial marketing efforts and expenditure of funds.

         Even if our customers do purchase our products in meaningful
quantities, due to the variety and complexity of the environments in which these
customers operate our products may not operate as expected. This could result in
cancelled orders, delays and increased expenses. In addition, the success of
competing products and technologies, pricing pressures or manufacturing
difficulties could further reduce our profitability and the price of our common
stock.

IF WE FAIL TO KEEP UP WITH TECHNOLOGICAL FACTORS AND FAIL TO DEVELOP OUR
PRODUCTS, WE MAY BE AT A COMPETITIVE DISADVANTAGE.

         We are continually seeking to refine and improve the design and
performance of our products. Our efforts remain subject to all of the risks
inherent in product development, including unanticipated technical, regulatory
or other problems that could result in material delays in product development or
commercialization or significantly increase costs. We may be required to commit
considerable additional efforts, time and resources to develop production
versions of additional products. Our success will depend upon new 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 our proposed products will be successfully completed on a timely
basis, if at all, that they will meet projected price and 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 our test kits or
that product defects will not become apparent after commercial introduction of
our additional test kits. In the event that we are required to remedy defects in


                                       5


any of our products after commercial introduction, the costs to us could be
significant, which could have a material adverse effect on our revenues or
earnings.

WE FACE SIGNIFICANT COMPETITION IN THE DRUG TESTING MARKET AND POTENTIAL
TECHNOLOGICAL OBSOLESCENCE.

         We face competition from other manufacturers of drug test kits such as
Roche Diagnostics, Medox Scientific, Inc. and Biosite Diagnostics. These
competitors are more well known and have far greater financial resources than
us. The markets for drug test kits and related products are highly competitive.
There can be no assurance that other companies will not attempt to develop or
market products directly competitive with the Rapid Drug Screen product line or
Rapid One. We expect other companies to develop technologies or products, which
will compete with our products.

POSSIBLE INABILITY TO FIND AND ATTRACT QUALIFIED PERSONNEL.

         We will need additional skilled, sales and marketing, technical and
production personnel to grow the business. If we fail to retain our present
staff or attract additional qualified personnel our business could suffer.

WE DEPEND ON KEY PERSONNEL TO MANAGE OUR BUSINESS EFFECTIVELY.

         We are dependent on the expertise and experience of our senior
management such as Robert L. Aromando Jr., Chief Executive Officer, Stan
Cipkowski, President, Douglas Casterlin, Vice President of Operations, Martin
Gould, Vice President of Technology and Keith Palmer, Chief Financial Officer,
for our future success. The loss of Messrs. Aromando, Cipkowski, Casterlin,
Gould and/or Palmer could negatively impact our business and results of
operations. We do not maintain key man insurance for any of our management
employees.

FAILURE TO EFFECTIVELY MANAGE OUR GROWTH AND EXPANSION COULD ADVERSELY AFFECT
OUR BUSINESS AND OPERATING RESULTS.

         We anticipate expansion of our operations in the coming year. Any
failure to manage our growth effectively will result in less efficient
operations, which could adversely affect our operating and financial results.

To effectively manage our growth, we must, among other things:

         o  accurately estimate the number of employees we will require and the
            areas in which they will be required; o upgrade and expand our
            office infrastructure so that it is appropriate for our level of
            activity;

         o  manage expansion into additional geographic areas; and o improve and
            refine our operating and financial systems.

         We expect to devote considerable resources and management time to
improving our operating and financial systems to manage our growth. Failure to
accomplish any of these objectives would impede our ability to deliver products
and services in a timely fashion, fulfill existing customer orders and attract
and retain new customers, which impediment would have a material adverse effect
on our financial condition and results of operations.


                                       6


ANY ADVERSE CHANGES IN OUR REGULATORY FRAMEWORK COULD NEGATIVELY IMPACT OUR
BUSINESS.

         Approval from the FDA is not required for the sale of the Rapid Drug
Screen in the non-clinical market, but it is required for the clinical and
over-the-counter markets. Regulatory standards may change in the future and
there is no assurance that if, and when, we apply for additional approvals from
the FDA they will be granted.

WE RELY ON INTELLECTUAL PROPERTY RIGHTS, AND WE MAY NOT BE ABLE TO OBTAIN PATENT
OR OTHER PROTECTION FOR OUR TECHNOLOGY, PRODUCTS OR SERVICES.

         We rely on a combination of patent, copyright, trademark and trade
secret laws, confidentiality procedures and contractual provisions to protect
our proprietary technology, products and services. We also believe that factors
such as the technological and creative skills of our personnel, new product
developments, frequent product enhancements and name recognition are essential
to establishing and maintaining our technology leadership position.

         We seek to protect our proprietary products under trade secret and
copyright laws, which afford only limited protection. We currently have ten
patents relating to the Rapid Drug Screen product line. We have applied for
additional patents on the Rapid Drug Screen and for certain trademarks in the
United States, South and Central America, European Common Market and Japan.
Certain trademarks have been registered and others are pending.

         Despite our efforts to protect our proprietary rights, unauthorized
parties may attempt to copy aspects of our products or to obtain information
that we regard as proprietary. For example, our sales were adversely affected in
fiscal 2000 and fiscal 2001 as a result of sales of products similar to ours. We
brought a lawsuit to stop these sales and incurred significant expenses in
attempting to enforce our patents. In April 2001, we settled with the defendants
in this lawsuit. We may be required to incur significant costs to protect our
intellectual property rights. In addition, the laws of some foreign countries do
not ensure that our means of protecting our proprietary rights in the United
States or abroad will be adequate. Policing and enforcement against the
unauthorized use of our intellectual property rights could entail significant
expenses and could prove difficult or impossible. Additionally, there is no
assurance that the additional patents will be granted or that additional
trademarks will be registered.

POTENTIAL ISSUANCE AND EXERCISE OF NEW WARRANTS AND EXERCISE OF OUTSTANDING
WARRANTS COULD ADVERSELY AFFECT OUR SHARE PRICE.

         In connection with our sale of 1,408,450 common shares for $2,000,000
($1.42 per share) in a private placement to Seaside Partners, L.P. on April 28,
2000, we issued a 5-year warrant to Seaside to purchase 953,283 common shares of
our stock at an exercise price of $1.1689 per share. To settle a penalty owed to
Seaside because of a late effective registration statement, we adjusted the
exercise price of the 953,283 warrant shares from $1.1689 to $0.95 in February
2001. In May 2001, we issued a 5-year warrant to purchase 200,000 common shares
of our stock at an exercise price of $1.50 per share to Brean Murray & Co., Inc.
as compensation for their services as a financial advisor. On August 22, 2001,
we issued warrants, exercisable during a 54 month period beginning February 22,
2001, to purchase 1,274,500 common shares of our stock at an exercise price of
$1.05 per share in connection with the private placement of 2,549,000 shares of
common stock. We also issued, on August 22, 2001, warrants, exercisable during a
54 month period beginning February 22, 2001, to purchase a total of 203,920
common shares of our stock at an exercise price of $1.20 per share, of which
warrants to purchase 152,940 common shares were issued to Brean Murray & Co.,
Inc. as compensation for their services as placement agent and warrants to
purchase 12,745 common shares were issued to Axiom Capital Management, Inc.,


                                       7


warrants to purchase 5,735 common shares were issued to Jeffrey Goldberg,
warrants to purchase 16,250 common shares were issued to Barry Zelin, warrants
to purchase 16,250 common shares were issued to David L. Jordon; for their
services as sub-agents of Brean Murray & Co., Inc.

         The exercise of the Seaside warrant, the Brean Murray Warrants and the
Private Placement Warrants and the sale of such shares could have a significant
negative impact on the market price of the common shares and could materially
impair our ability to raise capital through the future sale of equity
securities. The warrants are subject to or contain certain anti-dilution
protection that may result in the issuance of additional shares under some
circumstances.

SUBSTANTIAL RESALE OF RESTRICTED SECURITIES MAY DEPRESS THE MARKET PRICE OF OUR
STOCK.

         There are 7,329,955 common shares presently issued and outstanding as
of the date hereof that 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 that a person holding restricted securities for a period of one year or
more may, in any three month period, sell those securities in unsolicited
brokerage transactions or in transactions with a market maker, in an amount
equal to the greater of one percent of the our outstanding common shares or the
average weekly trading volume for the prior four weeks. 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. Investors
should be aware that sales under Rule 144 or 144(k), or pursuant to a
registration statement filed under the Act, may depress the market price of our
Company's securities in any market that may develop for such shares.

WE MAY NEED ADDITIONAL FUNDING FOR OUR EXISTING AND FUTURE OPERATIONS.

         We expect that with the proceeds from our August 2001 private placement
offering, our working capital will be sufficient to fund operations for at least
12 months. This estimate is based on certain assumptions and there can be no
assurance that unanticipated 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 Rapid
Drug Screen product line and Rapid One could make cash on hand insufficient to
fund operations. There can be no assurance that we will be able to obtain any
necessary financing on terms acceptable to us, if at all. Any financing may
result in further dilution to our existing shareholders.

         In addition, we will need to secure mortgage financing by the end of
September 2001 to purchase our facility in Kinderhook, New York. We cannot be
sure we will be able to secure this mortgage financing. If we are unable to do
so, we may be required to vacate this facility. This could have a material
adverse affect on our business and results of operations.

OUR ABILITY TO RETAIN AND ATTRACT MARKET MAKERS IS IMPORTANT TO THE CONTINUED
TRADING OF OUR STOCK.

         The common shares trade on the Nasdaq SmallCap Market under the symbol
"ABMC". In the event that the market makers cease to function as such, public
trading in common shares will be adversely affected or may cease entirely.


                                       8


MANAGEMENT HAS BROAD DISCRETION IN THE WAY WE USE THE NET PROCEEDS FROM THE
AUGUST 2001 PRIVATE PLACEMENT.

         Our business plan is subject to change based upon changing conditions
and opportunities. The net proceeds from the sale of the securities in the
August 2001 private placement have not been allocated for a particular purpose,
and our management will have broad discretion over the use of proceeds that we
raise in the offering. We intend to use the net proceeds for working capital,
settlement of legal fees at a discount and we may also use the net proceeds to
make investments in and acquisitions of complementary businesses, products or
technologies. You must rely on the judgment of management in the acquisition of
the proceeds, and you will not have the opportunity, as part of your investment
decisions, to assess whether these proceeds are being used appropriately.

                                 USE OF PROCEEDS

         We will not receive any proceeds from the common shares being sold in
this offering. The common shares will be offered and sold by the selling
shareholders for their own accounts. If all of the Investor Warrants are
exercised, the gross proceeds to us will be approximately $1,338,225. If the all
of the Placement Agent Warrants and the Brean Murray Warrants are exercised, the
gross proceeds to us will be $544,704. The Placement Agent Warrants and the
Brean Murray Warrants may be exercised using a "cashless exercise" feature
provided in the selling shareholders' warrant agreements, in which case we would
receive no cash proceeds from the exercise of those warrants. We intend to use
any such proceeds for working capital and general corporate purposes.

                              SELLING SHAREHOLDERS

         This is an offering, by the selling shareholders named below, of: (a)
up to 4,227,420 common shares, par value $0.01 per share, of American Bio Medica
Corporation, of which 2,549,000 are common shares of ABMC and 1,678,420 are
common shares issuable upon the exercise of common share purchase warrants and
(b) up to 1,274,500 common share purchase warrants. On August 22, 2001, the
selling shareholders acquired 2,549,000 common shares at a price of $1.00 per
share and 1,274,500 warrants ("Investor Warrants") to purchase one common share
at an exercise price of $1.05 per share and 203,920 warrants ("Placement Agent
Warrants") to purchase one common share at an exercise price of $1.20 per share,
exercisable during a 54 month period beginning on February 22, 2002. In
addition, on May 2, 2001, selling shareholders acquired 200,000 warrants ("Brean
Murray Warrants") to purchase one common share at an exercise price of $1.50 per
share during a five-year period. We are registering the selling shareholders'
resale of the common shares and the common shares issuable upon exercise of the
common share purchase warrants and the Investor Warrants pursuant to
Registration Rights Agreements between the selling shareholders and us. The
registration of these securities does not necessarily mean that any of them will
be offered or sold by the selling shareholders. The following table sets forth
the names of the selling shareholders, the number of common shares beneficially
owned by them as of September 24, 2001 (including common shares underlying the
Private Placement Warrants), the number of warrants to purchase common shares
owned by them as of September 24, 2001, the number of common shares, Investor
Warrants and common shares underlying the warrants being offered by each of them
pursuant to this Prospectus, and the number and percentage of common shares
owned by them after the offering, assuming all shares and warrants offered by
them are sold and are sold to third parties:

                              PLAN OF DISTRIBUTION

         The selling shareholders, or their pledgees, donees, transferees or
other successors in interest, may offer the securities covered by this
Prospectus to the public or otherwise from time to time. We are registering the
selling shareholders' resale of these securities pursuant to Registration Rights
Agreements between the selling shareholders and us. Pursuant to these
agreements, we have agreed to keep the registration statement related to this
Prospectus effective for two years. The registration of these securities does
not necessarily mean that any of them will be offered or sold by the selling
shareholders. The selling shareholders have informed us that any or all of the
securities covered by this Prospectus may be sold to purchasers directly by the


                                       12


selling shareholders, or their pledgees, donees, transferees or other successors
in interest, or on their behalf through brokers, dealers or agents in private or
market transactions, which may involve crosses or block transactions. In
connection with any sales, the selling shareholders and any brokers, dealers or
agents participating in such sales may be deemed to be "underwriters" within the
meaning of the Securities Act, and any profit on the sale of securities by them
and any discounts, concessions or commissions received by any brokers, dealers
or agents may be deemed to be underwriting discounts and commissions under the
Securities Act.

         The sales may be made, from time to time, in The Nasdaq Stock Market,
on any stock exchange, in the over-the-counter market, in privately negotiated
transactions or otherwise at prices prevailing in such market, at prices related
to market prices or at negotiated or fixed prices. In effecting sales, the
selling shareholders may engage brokers, dealers and agents, and they may
arrange for other brokers, dealers or agents to participate. Brokers, dealers
and agents will receive usual and customary commissions, concessions or
discounts from the selling shareholders in amounts to be negotiated, and, if the
broker, dealer or agent acts as agent for the purchaser of the common shares,
from the purchaser.

         Brokers, dealers or agents may agree with the selling shareholders to
sell a specified number of securities at a stipulated price per share, and, to
the extent such broker, dealer or agent is unable to do so acting as agent for a
selling shareholder, to purchase as principal any unsold securities at the price
required to fulfill the broker's, dealer's or agent's commitment to the selling
shareholder. Brokers, dealers or agents who acquire the securities as principal
may resell those securities from time to time in transactions, which may involve
crosses and block transactions and which may involve sales to and through other
brokers, dealers or agents, including transactions of the nature described above
in The Nasdaq Stock Market, on any stock exchange, in the over-the-counter
market, in negotiated transactions or otherwise, at market prices prevailing at
the time of sale, at prices related to market prices or at negotiated or fixed
prices., and in connection with these resales may pay to or receive from the
purchasers of securities commissions, concessions or discounts as described
above.

         We are bearing all of the costs relating to the registration of the
securities. Any commissions, concessions, discounts, or other fees payable to a
broker, dealer, agent or market maker in connection with any sale of securities
will be borne by the selling shareholder. We estimate that our total expenses of
this offering, other than such commissions, concessions, discounts or other
fees, will be approximately $55,000. We will not receive any of the proceeds
from the sale of the securities by the selling shareholders. We will receive
gross proceeds of up to $1,338,225 if all of the Investor Warrants are
exercised. If the all of the Placement Agent Warrants and the Brean Murray
Warrants are exercised, the gross proceeds to us will be $544,704. The Placement
Agent Warrants and the Brean Murray Warrants may be exercised using a "cashless
exercise" feature provided in the Placement Agent warrant agreements, in which
case we would receive no cash proceeds from the exercise of those warrants. We
have agreed to indemnify the selling shareholders or contribute to losses
arising out of certain liabilities that may be incurred in connection with this
offering, including liabilities under the Securities Act. The selling
shareholders have agreed to a similar indemnification of us.

         We have informed the selling shareholders that the anti-manipulation
provisions of Regulation M under the Exchange Act may apply to purchases and
sales of securities by the selling shareholders, and that there are restrictions
on market-making activities by persons engaged in the distribution of the
securities. We have also advised the selling shareholders that if a particular
offer of securities is to be made on terms constituting a material change from
the information described in this "Plan of Distribution" section of the
Prospectus, then, to the extent required, a Prospectus Supplement must be
distributed setting forth such terms and related information as required.

Item 15. Indemnification of Directors and Officers

         Under the New York Business Corporation Law ("NYBCL"), a corporation
may indemnify any person made, or threatened to be made, a party to any action
or proceeding, except for shareholder derivative suits, by reason of the fact
that he or she was a director or officer of the corporation, provided such
director or officer acted in good faith for a purpose which he or she reasonably
believed to be in the best interests of the corporation and, in criminal
proceedings, in addition, had no reasonable cause to believe his or her conduct
was unlawful. In the case of shareholder derivative suits, the corporation may
indemnify any person by reason of the fact that he or she was a director or
officer of the corporation if he or she acted in good faith for a purpose which
he or she reasonably believed to be in the best interests of the corporation,
except that no indemnification may be made in respect of (i) a threatened
action, or a pending action which is settled or otherwise disposed of; or (ii)
any claim, issue or matter as to which such person has 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 that
portion of the settlement amount and expenses as the court deems proper.

         The indemnification described above under the NYBCL is not exclusive of
other indemnification rights to which a director or officer may be entitled,
whether contained in the certificate of incorporation or by-laws, or when
authorized by (i) such certificate of incorporation or by-laws; (ii) a
resolution of shareholders; (iii) a resolution of directors; or (iv) 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 or
her 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
or she personally gained in fact a financial profit or other advantage to which
he or she was not legally entitled.

Item 16. Exhibits

         See Exhibit List on page E-1.

Item 17. Undertakings

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to our directors, officers and controlling persons pursuant
to the foregoing provisions, or otherwise, ABMC has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by ABMC of expenses incurred or paid by a
director, officer or controlling person of ABMC 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, we will, unless in
the opinion of our counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by us is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue. The Company will:

(a)      file, during any period in which it offers or sells securities, a
         post-effective amendment to this registration statement to include any
         additional or changed material information on the plan of distribution.

(b)      for determining liability under the Securities Act, treat each
         post-effective amendment as a new registration statement of the
         securities offered, and the offering of the securities at that time to
         be the initial bona fide offering.

(c)      file a post-effective amendment to remove from registration any of the
         securities that remain unsold at the end of the offering.

         Re: Form S-3 Registration Statement


Ladies and Gentlemen:

         We have acted as counsel for American Bio Medica Corporation (the
"Company") in connection with the registration under the Securities Act of 1933,
as amended (the "Securities Act") of (a) 4,227,420 common shares ("Shares"), par
value $0.01 per share, of the Company, of which 2,549,000 are common shares of
ABMC and 1,678,420 are common shares issuable upon the exercise of common share
purchase warrants ("Shares") and (b) up to 1,274,500 common share purchase
warrants ("Warrants").

         We have reviewed the corporate proceedings with respect to the
authorization of the issuance of the Shares and the Warrants. We have also
reviewed such questions of law, as we have deemed necessary and appropriate for
the purposes of rendering the opinion set forth below. In rendering our opinion,
we have assumed the authenticity of all documents submitted to us, the
genuineness of all signatures and the conformity to authentic originals of all
documents submitted to us as copies. We have also assumed the legal capacity for
all purposes relevant hereto of all natural person and with respect to all
parties to agreements or instruments relevant hereto other than Company, that
such parties had the requisite power and authority (corporate or otherwise), to
execute and deliver such agreements or instruments and that such agreements or
instruments are the valid, binding and enforceable obligations of such parties.

         Based on the foregoing, it is our opinion that the Shares, including
the common shares issuable upon exercise of the Warrants, and Warrants, when
sold in the manner described in the Registration Statement, will be legally
issued, fully paid and nonassessable.

         Our opinion expressed above is limited solely to the Business
Corporation Law of the State of New York ("BCL"), and the federal laws of the
United States of America, in each case to the extent that the same may apply to
or govern such opinion, and we express no opinion as to the laws of any other
jurisdiction.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.

                                             Very truly yours,

                                             Tuczinski, Burstein & Collura, P.C.

INDEPENDENT AUDITORS' CONSENT

We consent to the incorporation by reference in this Registration Statement on

L[5], July 23, 2001; with respect to the last paragraph of Note J[3], July 18,

Company for the year ended April 30, 2001, and to the reference to us under the
heading "Experts" in the Prospectus, which is part of this Registration
Statement.

financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

Exhibit 4.2  Investor Registration Rights Agreement

                          REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT ("Agreement") is made as of August
22, 2001, by and among American Bio Medica Corporation, a New York corporation
(the "Company"), and the persons signing the signature page of this Agreement
who have entered into Subscription Agreements, dated August 2001, to purchase
the Company's common stock (the "Shareholders").

                                    RECITALS

         A. Pursuant to Subscription Agreements, dated August 2001 (the
"Subscription Agreements"), the Shareholders have purchased shares (the "Common
Shares") of the Company's common stock, par value $0.01 per share ("Common
Stock"), and warrants (the "Common Stock Warrants") entitling the holders
thereof to purchase the number of shares (the "Warrant Shares") of Common Stock
as set forth therein.

         B. To induce the Shareholders to purchase Common Shares and Common
Stock Warrants, the Company has agreed to provide the Shareholders with certain
registration rights described herein.

         THEREFORE, in consideration of the promises and the mutual covenants
and agreements contained in the Subscription Agreements and other good and
valuable consideration, receipt of which is hereby acknowledged, the parties
hereby agree as follows:

         1.  Definitions. For purposes of this Agreement, the following terms
shall have the following meanings:

             Person. An individual, partnership, corporation, limited liability
         company, trust or unincorporated organization, or a government or
         agency or political subdivision thereof.

             Prospectus. The prospectus included in any Registration Statement,
         as amended or supplemented by any prospectus supplement, including
         post-effective amendments and all material incorporated by reference in
         the prospectus.

             Registration Statement. Any registration statement of the Company
         which covers any of the Registrable Securities (as defined in Section 2
         hereof) pursuant to the provisions of this Agreement, including the
         registration statement and amendments and post-effective amendments
         thereto, the Prospectus and supplements therein, all exhibits and all
         material incorporated by reference in the registration statement.

             SEC. The U.S. Securities and Exchange Commission.

             Securities Act. The Securities Act of 1933, as amended.

             Shares. The Common Shares and the Warrant Shares.

         2.  Securities Subject to this Agreement. The securities entitled to
the benefit of this Agreement are all the Shares and the Common Stock Warrants
(the "Registrable Securities"); provided, however, that the Shares and the
Common Stock Warrants shall be Registrable Securities only for so long as the
Shares and the Common Stock Warrants continue to be Restricted Securities. For



purposes of this Agreement, the Shares and the Common Stock Warrants shall be
Restricted Securities as of the date of this Agreement. The Shares and the
Common Stock Warrants shall cease to be Restricted Securities when (1) the
Company has effectively registered the Shares and the Common Stock Warrants
under the Securities Act and the Shareholders who own the Shares and the Common
Stock Warrants, have disposed of the Shares and the Common Stock Warrants in
accordance with the Registration Statement covering the Shares and the Common
Stock Warrants, (2) the Shareholders who own Shares and Common Stock Warrants,
shall be eligible to sell the Shares and the Common Stock Warrants to the public
in accordance with all applicable conditions of Rule 144 (or any similar
provisions then in force) under the Securities Act, or such Shares and Common
Stock Warrants may be sold pursuant to Rule 144(k) (or any similar provision
then in force) under the Securities Act, and are freely tradable after such sale
by the transferee, (3) the Shareholders have otherwise transferred the Shares
and the Common Stock Warrants (except as otherwise provided in Section 7(h)
hereof), or (4) such Shares or Common Stock Warrants shall have ceased to be
outstanding.

         3.  Registration of Registrable Securities. On or before the later of
(i) August 15, 2001 or (ii) the thirtieth business day after the date American
Bio Medica issues Common Shares and Common Stock Warrants, the Company will use
its best efforts to cause a Registration Statement to be filed with the SEC
covering the Registrable Securities. The Company shall also use its commercially
reasonable efforts to cause such Registration Statement to become effective
within 45 days after such filing (or 90 days if reviewed by the Staff of the
SEC) and, subject to the provisions of Section 2 hereof, remain effective until
two years after the last date Common Shares and Common Stock Warrants are issued
to such Shareholders pursuant to the Subscription Agreements.

         4.  Registration Procedures.

             (a) The Company shall:

                 (i) furnish to the Shareholders, without charge, at least one
             signed copy of the Registration Statement and any post-effective
             amendment thereto, including financial statements and schedules,
             all documents incorporated by reference therein and all exhibits
             (including those incorporated by reference);

                 (ii) deliver to the Shareholders, without charge, as many
             copies of the Prospectus (including each preliminary Prospectus)
             and any amendment or supplement thereto as they may reasonably
             request, but only while the Company is required to cause the
             Registration Statement to remain effective;

                 (iii) prior to any public offering of Registrable Securities,
             register or qualify or cooperate with the Shareholders and their
             respective counsel in connection with the registration or
             qualification of the Registrable Securities for offer and sale
             under the securities laws of the various states (the "Blue Sky
             Laws") and do any and all other acts or things reasonably necessary
             or advisable to effect the registration or qualification of the
             Registrable Securities covered by the Registration Statement in the
             various states; provided, however, that in no event shall the
             Company be obligated to qualify to do business in any jurisdiction
             where it is not now qualified or to take any action which would
             subject it to taxation or service of process in suits other than
             those arising out of the offer or sale of the securities covered by
             such Registration Statement in any jurisdictions where it is not
             now so subject;

                 (iv) cooperate with the Shareholders to prepare and deliver
             timely certificates representing Registrable Securities to be sold
             and not bearing any restrictive legends; and issue the Registrable
             Securities in the denominations and register them in the names the



             Shareholders may request at least two (2) business days prior to
             any sale of Registrable Securities;

                 (v) use its best efforts to cause a Notification Form for
             Listing of Additional Shares to be filed with The Nasdaq Stock
             Market with respect to the Registrable Securities being registered
             or to cause similar required forms to be filed with the market on
             which similar securities issued by the Company are then listed or
             traded; and

                 (vi) make available to the Shareholders and any attorney or
             accountant retained by the Shareholders for inspection all
             financial and other records, pertinent corporate documents and
             properties of the Company, and cause the Company's officers,
             directors and employees to supply all information that the
             participating Shareholders, the Shareholders' representatives,
             attorneys or accountants may reasonably request in connection with
             the registration; provided, that such Persons shall keep
             confidential any records, information or documents that the Company
             designates as confidential unless a court or administrative agency
             requires the disclosure of the records, information or documents.

             (b) Each of the Shareholders agrees to furnish the Company with any
         information regarding the Shareholders and the distribution of the
         Registrable Securities as the Company may from time to time reasonably
         request.

             (c) The Shareholders agree that, upon receipt of any notice from
         the Company of the happening of any of the following: (i) the SEC's
         issuance of any stop order denying or suspending the effectiveness of
         the Registration Statement or the initiation or threatening of any
         proceeding for that purpose, (ii) the Company's receipt of any stop
         order denying registration or suspending the qualification of the
         Registrable Securities for sale or the initiation or threatening of any
         proceeding for such purpose, or (iii) the happening of any event which
         makes any statement made in the Registration Statement, the Prospectus
         or any document incorporated by reference therein untrue or which
         requires any change in the Registration Statement, the Prospectus or
         any document incorporated by reference therein to make the statements
         not include an untrue statement of material fact or not omit any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading in light of the circumstances then
         existing, the Shareholders shall discontinue the disposition of
         Registrable Securities until the Shareholders receive a supplemented or
         amended Prospectus from the Company or until the Company advises the
         Shareholders in writing that the participating Shareholders may resume
         the use of the Prospectus, and have received copies of any additional
         or supplemental filings which are incorporated by reference in the
         Prospectus. If the Company so directs, the Shareholders will deliver to
         the Company all copies, other than permanent file copies then in the
         Shareholders' possession, of the Prospectus covering the Registrable
         Securities at the time the Shareholders received the notice.

         5.  Registration Expenses. Regardless of when the Registration
Statement becomes effective, the Company shall bear all costs and expenses
incident to the Company's performance of, or compliance with, this Agreement,
including without limitation all registration and filing fees, fees and expenses
of compliance with the Blue Sky Laws, printing expenses, messenger, telephone
and delivery expenses, and fees and disbursements of counsel for the Company,
all independent certified public accountants of the Company, and fees and
expenses of other Persons retained by the Company relating to the distribution
of the Registrable Securities (all such expenses being called "Registration
Expenses"). The participating Shareholders shall in all cases bear all
discounts, fees or commissions incident to the sale of the Shareholders'
Registrable Securities and any fees of any attorney or accountant retained by
any of the Shareholders.



         6.  Indemnification.

             (a) Indemnification by the Company. The Company agrees to indemnify
         and hold harmless, to the full extent permitted by law, the
         Shareholders against all losses, claims, damages, liabilities and
         expenses, joint or several, to which the Shareholders may become
         subject under the Securities Act or any state securities law, or any
         rule or regulation promulgated under the Securities Act or otherwise
         which arise out of, or are caused by, the Company's violation of the
         Securities Act or any state securities laws, or any rule or regulation
         promulgated under the Securities Act, including, but not limited to,
         any untrue or alleged untrue statement of a material fact contained in
         any Registration Statement, Prospectus or preliminary Prospectus or in
         any application or other request that the Company files, including any
         application or request filed under the Blue Sky Laws, or any omission
         or alleged omission to state therein a material fact required to be
         stated therein or necessary to make the statements therein not
         misleading, except insofar as the same are based upon an untrue or
         alleged untrue statement or omission or alleged omission so made which
         is contained in information furnished to the Company by any of the
         Shareholders expressly for use therein or by any Shareholder's failure
         to deliver a copy of the Registration Statement or Prospectus after the
         Company has furnished the participating Shareholders with a copy of the
         same. The Company will reimburse the Shareholders for any legal or
         other expense the Shareholders reasonably incur in connection with
         investigating or defending any such loss, claim, damage, liability,
         action or proceeding. The Company will also indemnify the selling
         brokers, dealer managers and similar securities industry professionals
         participating in the distribution, their officers and directors and
         each Person who controls such persons (within the meaning of the
         Securities Act) to the same extent as provided above with respect to
         the indemnification of the Shareholders, if requested.

             (b) Indemnification by the Shareholders. In connection with any
         Registration Statement in which any Shareholder's Registrable
         Securities are registered and sold, the participating Shareholders
         shall furnish to the Company the information and affidavits as the
         Company reasonably requests for use in connection with any Registration
         Statement or Prospectus and agree, jointly and severally, to indemnify
         and hold harmless, to the full extent permitted by law, the Company,
         its officers directors and each Person who controls the Company (within
         the meaning of the Securities Act) against any losses, claims, damages,
         liabilities and expenses resulting from any untrue or alleged untrue
         statement of a material fact or any omission or alleged omission of a
         material fact required to be stated in the Registration Statement,
         Prospectus, preliminary Prospectus or any application filed under the
         Blue Sky Laws or necessary to make the statements therein not
         misleading, to the extent, but only to the extent, that the untrue
         statement or omission is contained in any information or affidavit so
         furnished by the Shareholder to the Company specifically for inclusion
         in the Registration Statement, Prospectus or application filed under
         the Blue Sky Laws. The Company shall be entitled to receive indemnities
         from selling brokers, dealer managers and similar securities industry
         professionals participating in the distribution, to the same extent as
         provided above with respect to information so furnished by the Persons
         specifically for inclusion in any Prospectus or Registration Statement.

             (c) Conduct of Indemnification Proceedings. Any Person entitled to
         indemnification hereunder shall (1) promptly notify the indemnifying
         party of any claim with respect to which it seeks indemnification and
         (2) permit such indemnifying party to assume the defense of such claim
         with counsel reasonably satisfactory to the indemnified party. Any
         Person entitled to indemnification hereunder shall have the right to
         employ separate counsel and to participate in the defense of the claim,
         but the fees and expenses of the counsel shall be at the expense of the
         Person unless (A) the indemnifying party has agreed to pay the fees or
         expenses, (B) the indemnifying party shall have failed to assume the
         defense of the claim and employ counsel reasonably satisfactory to the
         Person, or (C) in the reasonable judgment of the Person, based upon



         advice of its counsel, a conflict of interest may exist between the
         Person and the indemnifying party with respect to the claims (in which
         case, if the Person notifies the indemnifying party in writing that the
         Person elects to employ separate counsel at the expense of the
         indemnifying party, the indemnifying party shall not have the right to
         assume the defense of the claim on behalf of the Person). The
         indemnifying party will not be subject to any liability for any
         settlement made without its consent. The indemnifying party, however,
         may not unreasonably withhold its consent. No indemnifying party will
         be required to consent to the entry of any judgment or to enter into
         any settlement which does not include as an unconditional term the
         claimant's or plaintiff's release of the indemnified party from all
         liability in respect to the claim or litigation. An indemnifying party
         who is not entitled to, or elects not to, assume the defense of a claim
         shall not be obligated to pay the fees and expenses of more than one
         counsel for all parties indemnified by the indemnifying party with
         respect to the claim, unless in the reasonable judgment of any
         indemnified party a conflict of interest may exist between such
         indemnified party and any other of such indemnified parties with
         respect to the claim, in which event the indemnifying party shall be
         obligated to pay the fees and expenses of such additional counsel or
         counsels.

             (d) Contribution. If for any reason the indemnification provided
         for in the preceding clauses (a) and (b) is unavailable to an
         indemnified party or insufficient to hold it harmless as contemplated
         by the preceding clauses (a) and (b), then the indemnifying party shall
         contribute to the amount paid or payable by the indemnified party as a
         result of the loss, claim, damage liability or expense in the
         proportion as is appropriate to reflect (1) the relative benefits
         received by the indemnified party and the indemnifying party, (2) the
         relative fault of the indemnified party and the indemnifying party, and
         (3) any other relevant equitable considerations.

             (e) The indemnities provided in this Section 6 shall survive the
         Shareholders' transfer of any Registrable Securities.

         7.  Miscellaneous.

             (a) Other Agreements. The Shareholders acknowledge that the Company
         has granted registration rights to others and the rights granted in
         this Agreement are subject to those rights already granted.

             (b) Amendments and Waivers. No amendment, modification, supplement
         or waiver of any provision of this Agreement is binding on any party
         unless the party consents in writing thereto.

             (c) Notices. Any notice or other communication required or which
         may be given under this Agreement shall be in writing and either
         delivered personally to the addressee, telegraphed, telecopied or
         telexed to the addressee, sent by overnight courier to the addressee or
         mailed, certified or registered mail, postage prepaid, and shall be
         deemed given when so delivered personally, telegraphed, telecopied or
         telexed to the addressee, or, if sent by overnight courier, on the day
         delivery is guaranteed by such courier, or, if mailed, three business
         days after the date of mailing, as follows:

                 (i)   to the Shareholders, at the most current address given by
             the Shareholders to the Company pursuant to the Subscription
             Agreements or otherwise.



                 (ii)  To American Bio Medica at:

                       American Bio Medica Corporation
                       122 Smith Road
                       Kinderhook, New York 12106
                       Attention:  President

                       With a copy to:

                       Fulbright & Jaworski L.L.P.
                       666 Fifth Avenue
                       New York, New York 10103
                       Attention: Neil Gold, Esq.

         Any of the foregoing may change its address for notices by notice to
the other parties.

             (d) Governing Law and Forum. The laws of the State of New York
         shall govern this Agreement, its construction, and the determination of
         any rights, duties or remedies of the parties arising out of, or
         relating to, this Agreement (regardless of the laws that might
         otherwise govern under applicable New York principles of conflicts of
         law). The parties acknowledge that the United States District Court for
         the Southern District of New York or the New York Supreme Court for the
         County of Columbia shall have exclusive jurisdiction over any case or
         controversy arising out of, or relating to, this Agreement and that all
         litigation arising out of, or relating to, this Agreement shall be
         commenced in the United States District Court for the Southern District
         of New York or in the Columbia County (New York) Supreme Court. Each of
         the parties consents to be subject to personal jurisdiction of the
         courts of New York, including the federal courts in New York.

             (e) Counterparts. This Agreement may be executed in two or more
         counterparts, each of which shall be deemed an original, but all of
         which together shall constitute one and the same instrument.

             (f) Interpretation. The Section headings contained in this
         Agreement are for the purposes of reference, are not part of the
         agreement of the parties and shall not in any way affect the meaning or
         interpretation of this Agreement.

             (g) Severability. If any provision of this Agreement is determined
         to be illegal or invalid, such illegality or invalidity shall have no
         effect on the other provisions of this Agreement, and all other
         provisions of this Agreement shall remain valid, operative and
         enforceable.

             (h) Assignment. The rights granted to the Shareholders pursuant to
         this Agreement shall not be assignable without the written consent of
         the Company.



         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first written above.

Exhibit 4.3 Placement Agent Registration Rights Agreement

                          REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT ("Agreement") is made as of August
22, 2001, by and among American Bio Medica Corporation, a New York corporation
(the "Company"), and the persons signing the signature page of this Agreement
who have acted as placement agent or sub-agents (the "Placement Agents") in
connection with the August 2001 private placement of the Company's common
shares.

                                    RECITALS

         A. Pursuant to an engagement letter (the "Engagement Letter"), dated
June 4, 2001, the Placement Agents have been issued warrants (the "Common Stock
Warrants") entitling the holders thereof to purchase the number of shares (the
"Warrant Shares") of Common Stock as set forth therein.

         B. The Company has agreed to provide the Placement Agents with certain
registration rights described herein.

         THEREFORE, in consideration of the promises and the mutual covenants
and agreements contained in the Engagement Letter and other good and valuable
consideration, receipt of which is hereby acknowledged, the parties hereby agree
as follows:

         1.  Definitions. For purposes of this Agreement, the following terms
shall have the following meanings:

             Person. An individual, partnership, corporation, limited liability
         company, trust or unincorporated organization, or a government or
         agency or political subdivision thereof.

             Prospectus. The prospectus included in any Registration Statement,
         as amended or supplemented by any prospectus supplement, including
         post-effective amendments and all material incorporated by reference in
         the prospectus.

             Registration Statement. Any registration statement of the Company
         which covers any of the Registrable Securities (as defined in Section 2
         hereof) pursuant to the provisions of this Agreement, including the
         registration statement and amendments and post-effective amendments
         thereto, the Prospectus and supplements therein, all exhibits and all
         material incorporated by reference in the registration statement.

             SEC. The U.S. Securities and Exchange Commission.

             Securities Act. The Securities Act of 1933, as amended.

             Shares. The Common Shares and the Warrant Shares.

         2.  Securities Subject to this Agreement. The securities entitled to
the benefit of this Agreement are all the Common Shares issuable upon exercise
of the Common Stock Warrants (the "Registrable Securities"); provided, however,
that the Common Shares issuable upon exercise of the Common Stock Warrants shall



be Registrable Securities only for so long as the Common Shares continue to be
Restricted Securities. For purposes of this Agreement, the Common Shares
issuable upon exercise of the Common Stock Warrants shall be Restricted
Securities as of the date of this Agreement. The Common Shares issuable upon
exercise of the Common Stock Warrants shall cease to be Restricted Securities
when (1) the Company has effectively registered the Common Shares issuable upon
exercise of the Common Stock Warrants under the Securities Act and the Placement
Agents who own the Common Shares issuable upon the exercise of the Common Stock
Warrants, have disposed of the Common Shares issuable upon exercise of the
Common Stock Warrants in accordance with the Registration Statement covering the
Common Shares issuable upon exercise of the Common Stock Warrants, (2) the
Placement Agents who own Common Shares issuable upon the exercise of the Common
Stock Warrants, shall be eligible to sell the Common Shares issuable upon
exercise of the Common Stock Warrants to the public in accordance with all
applicable conditions of Rule 144 (or any similar provisions then in force)
under the Securities Act, or such Common Shares issuable upon the exercise of
the Common Stock Warrants may be sold pursuant to Rule 144(k) (or any similar
provision then in force) under the Securities Act, and are freely tradable after
such sale by the transferee, (3) the Placement Agents have otherwise transferred
the Common Shares issuable upon the exercise of the Common Stock Warrants
(except as otherwise provided in Section (h) hereof), or (4) such Common Shares
issuable upon the exercise of the Common Stock Warrants shall have ceased to be
outstanding.

         3.  Registration of Registrable Securities. On or before the later of
(i) August 15, 2001 or (ii) the thirtieth business day after the date American
Bio Medica issues the Common Stock Warrants, the Company will use its best
efforts to cause a Registration Statement to be filed with the SEC covering the
Registrable Securities. The Company shall also use its commercially reasonable
efforts to cause such Registration Statement to become effective within 45 days
after such filing (or 90 days if reviewed by the Staff of the SEC) and, subject
to the provisions of Section 2 hereof, remain effective until two years after
the last date Common Shares issuable upon the exercise of the Common Stock
Warrants are issued to such Placement Agents pursuant to the Engagement Letter.

         4.  Registration Procedures.

             (a) The Company shall:

                 (i) furnish to the Placement Agents, without charge, at least
             one signed copy of the Registration Statement and any
             post-effective amendment thereto, including financial statements
             and schedules, all documents incorporated by reference therein and
             all exhibits (including those incorporated by reference);

                 (ii) deliver to the Placement Agents, without charge, as many
             copies of the Prospectus (including each preliminary Prospectus)
             and any amendment or supplement thereto as they may reasonably
             request, but only while the Company is required to cause the
             Registration Statement to remain effective;

                 (iii) prior to any public offering of Registrable Securities,
             register or qualify or cooperate with the Placement Agents and
             their respective counsel in connection with the registration or
             qualification of the Registrable Securities for offer and sale
             under the securities laws of the various states (the "Blue Sky
             Laws") and do any and all other acts or things reasonably necessary
             or advisable to effect the registration or qualification of the
             Registrable Securities covered by the Registration Statement in the
             various states; provided, however, that in no event shall the
             Company be obligated to qualify to do business in any jurisdiction
             where it is not now qualified or to take any action which would
             subject it to taxation or service of process in suits other than
             those arising out of the offer or sale of the securities covered by
             such Registration Statement in any jurisdictions where it is not
             now so subject;

                 (iv) cooperate with the Placement Agents to prepare and deliver
             timely certificates representing Registrable Securities to be sold
             and not bearing any restrictive legends; and issue the Registrable
             Securities in the denominations and register them in the names the
             Placement Agents may request at least two (2) business days prior
             to any sale of Registrable Securities;



                 (v) use its best efforts to cause a Notification Form for
             Listing of Additional Shares to be filed with The Nasdaq Stock
             Market with respect to the Registrable Securities being registered
             or to cause similar required forms to be filed with the market on
             which similar securities issued by the Company are then listed or
             traded; and

                 (vi) make available to the Placement Agents and any attorney or
             accountant retained by the Placement Agents for inspection all
             financial and other records, pertinent corporate documents and
             properties of the Company, and cause the Company's officers,
             directors and employees to supply all information that the
             participating Placement Agents, the Placement Agents'
             representatives, attorneys or accountants may reasonably request in
             connection with the registration; provided, that such Persons shall
             keep confidential any records, information or documents that the
             Company designates as confidential unless a court or administrative
             agency requires the disclosure of the records, information or
             documents.

             (b) Each of the Placement Agents agree to furnish the Company with
         any information regarding the Placement Agents and the distribution of
         the Registrable Securities as the Company may from time to time
         reasonably request.

             (c) The Placement Agents agree that, upon receipt of any notice
         from the Company of the happening of any of the following: (i) the
         SEC's issuance of any stop order denying or suspending the
         effectiveness of the Registration Statement or the initiation or
         threatening of any proceeding for that purpose, (ii) the Company's
         receipt of any stop order denying registration or suspending the
         qualification of the Registrable Securities for sale or the initiation
         or threatening of any proceeding for such purpose, or (iii) the
         happening of any event which makes any statement made in the
         Registration Statement, the Prospectus or any document incorporated by
         reference therein untrue or which requires any change in the
         Registration Statement, the Prospectus or any document incorporated by
         reference therein to make the statements not include an untrue
         statement of material fact or not omit any material fact required to be
         stated therein or necessary to make the statements therein not
         misleading in light of the circumstances then existing, the Placement
         Agents shall discontinue the disposition of Registrable Securities
         until the Placement Agents receive a supplemented or amended Prospectus
         from the Company or until the Company advises the Placement Agents in
         writing that the participating Placement Agents may resume the use of
         the Prospectus, and have received copies of any additional or
         supplemental filings which are incorporated by reference in the
         Prospectus. If the Company so directs, the Placement Agents will
         deliver to the Company all copies, other than permanent file copies
         then in the Placement Agents' possession, of the Prospectus covering
         the Registrable Securities at the time the Placement Agents received
         the notice.

         5.  Registration Expenses. Regardless of when the Registration
Statement becomes effective, the Company shall bear all costs and expenses
incident to the Company's performance of, or compliance with, this Agreement,
including without limitation all registration and filing fees, fees and expenses
of compliance with the Blue Sky Laws, printing expenses, messenger, telephone
and delivery expenses, and fees and disbursements of counsel for the Company,
all independent certified public accountants of the Company, and fees and
expenses of other Persons retained by the Company relating to the distribution
of the Registrable Securities (all such expenses being called "Registration
Expenses"). The participating Placement Agents shall in all cases bear all
discounts, fees or commissions incident to the sale of the Placement Agents'
Registrable Securities and any fees of any attorney or accountant retained by
any of the Placement Agents.



         6.  Indemnification.

             (a) Indemnification by the Company. The Company agrees to indemnify
         and hold harmless, to the full extent permitted by law, the Placement
         Agents against all losses, claims, damages, liabilities and expenses,
         joint or several, to which the Placement Agents may become subject
         under the Securities Act or any state securities law, or any rule or
         regulation promulgated under the Securities Act or otherwise which
         arise out of, or are caused by, the Company's violation of the
         Securities Act or any state securities laws, or any rule or regulation
         promulgated under the Securities Act, including, but not limited to,
         any untrue or alleged untrue statement of a material fact contained in
         any Registration Statement, Prospectus or preliminary Prospectus or in
         any application or other request that the Company files, including any
         application or request filed under the Blue Sky Laws, or any omission
         or alleged omission to state therein a material fact required to be
         stated therein or necessary to make the statements therein not
         misleading, except insofar as the same are based upon an untrue or
         alleged untrue statement or omission or alleged omission so made which
         is contained in information furnished to the Company by any of the
         Placement Agents expressly for use therein or by any Shareholder's
         failure to deliver a copy of the Registration Statement or Prospectus
         after the Company has furnished the participating Placement Agents with
         a copy of the same. The Company will reimburse the Placement Agents for
         any legal or other expense the Placement Agents reasonably incur in
         connection with investigating or defending any such loss, claim,
         damage, liability, action or proceeding. The Company will also
         indemnify the selling brokers, dealer managers and similar securities
         industry professionals participating in the distribution, their
         officers and directors and each Person who controls such persons
         (within the meaning of the Securities Act) to the same extent as
         provided above with respect to the indemnification of the Placement
         Agents, if requested.

             (b) Indemnification by the Placement Agents. In connection with any
         Registration Statement in which any Shareholder's Registrable
         Securities are registered and sold, the participating Placement Agents
         shall furnish to the Company the information and affidavits as the
         Company reasonably requests for use in connection with any Registration
         Statement or Prospectus and agree, jointly and severally, to indemnify
         and hold harmless, to the full extent permitted by law, the Company,
         its officers directors and each Person who controls the Company (within
         the meaning of the Securities Act) against any losses, claims, damages,
         liabilities and expenses resulting from any untrue or alleged untrue
         statement of a material fact or any omission or alleged omission of a
         material fact required to be stated in the Registration Statement,
         Prospectus, preliminary Prospectus or any application filed under the
         Blue Sky Laws or necessary to make the statements therein not
         misleading, to the extent, but only to the extent, that the untrue
         statement or omission is contained in any information or affidavit so
         furnished by the Shareholder to the Company specifically for inclusion
         in the Registration Statement, Prospectus or application filed under
         the Blue Sky Laws. The Company shall be entitled to receive indemnities
         from selling brokers, dealer managers and similar securities industry
         professionals participating in the distribution, to the same extent as
         provided above with respect to information so furnished by the Persons
         specifically for inclusion in any Prospectus or Registration Statement.

             (c) Conduct of Indemnification Proceedings. Any Person entitled to
         indemnification hereunder shall (1) promptly notify the indemnifying
         party of any claim with respect to which it seeks indemnification and
         (2) permit such indemnifying party to assume the defense of such claim
         with counsel reasonably satisfactory to the indemnified party. Any
         Person entitled to indemnification hereunder shall have the right to
         employ separate counsel and to participate in the defense of the claim,
         but the fees and expenses of the counsel shall be at the expense of the



         Person unless (A) the indemnifying party has agreed to pay the fees or
         expenses, (B) the indemnifying party shall have failed to assume the
         defense of the claim and employ counsel reasonably satisfactory to the
         Person, or (C) in the reasonable judgment of the Person, based upon
         advice of its counsel, a conflict of interest may exist between the
         Person and the indemnifying party with respect to the claims (in which
         case, if the Person notifies the indemnifying party in writing that the
         Person elects to employ separate counsel at the expense of the
         indemnifying party, the indemnifying party shall not have the right to
         assume the defense of the claim on behalf of the Person). The
         indemnifying party will not be subject to any liability for any
         settlement made without its consent. The indemnifying party, however,
         may not unreasonably withhold its consent. No indemnifying party will
         be required to consent to the entry of any judgment or to enter into
         any settlement which does not include as an unconditional term the
         claimant's or plaintiff's release of the indemnified party from all
         liability in respect to the claim or litigation. An indemnifying party
         who is not entitled to, or elects not to, assume the defense of a claim
         shall not be obligated to pay the fees and expenses of more than one
         counsel for all parties indemnified by the indemnifying party with
         respect to the claim, unless in the reasonable judgment of any
         indemnified party a conflict of interest may exist between such
         indemnified party and any other of such indemnified parties with
         respect to the claim, in which event the indemnifying party shall be
         obligated to pay the fees and expenses of such additional counsel or
         counsels.

             (d) Contribution. If for any reason the indemnification provided
         for in the preceding clauses 6(a) and 6(b) is unavailable to an
         indemnified party or insufficient to hold it harmless as contemplated
         by the preceding clauses 6(a) and 6(b), then the indemnifying party
         shall contribute to the amount paid or payable by the indemnified party
         as a result of the loss, claim, damage liability or expense in the
         proportion as is appropriate to reflect (1) the relative benefits
         received by the indemnified party and the indemnifying party, (2) the
         relative fault of the indemnified party and the indemnifying party, and
         (3) any other relevant equitable considerations.

             (e) The indemnities provided in this Section 6 shall survive the
         Placement Agents' transfer of any Registrable Securities.

         7.  Miscellaneous.

             (a) Other Agreements. The Placement Agents acknowledge that the
         Company has granted registration rights to others and the rights
         granted in this Agreement are subject to those rights already granted.

             (b) Amendments and Waivers. No amendment, modification, supplement
         or waiver of any provision of this Agreement is binding on any party
         unless the party consents in writing thereto.

             (c) Notices. Any notice or other communication required or which
         may be given under this Agreement shall be in writing and either
         delivered personally to the addressee, telegraphed, telecopied or
         telexed to the addressee, sent by overnight courier to the addressee or
         mailed, certified or registered mail, postage prepaid, and shall be
         deemed given when so delivered personally, telegraphed, telecopied or
         telexed to the addressee, or, if sent by overnight courier, on the day
         delivery is guaranteed by such courier, or, if mailed, three business
         days after the date of mailing, as follows:

                 (i) to the Placement Agents, at the most current address given
             by the Placement Agents to the Company pursuant to the Subscription
             Agreements or otherwise.



                 (ii) To American Bio Medica at:

                      American Bio Medica Corporation
                      122 Smith Road
                      Kinderhook, New York 12106
                      Attention:  President

                      With a copy to:

                      Fulbright & Jaworski L.L.P.
                      666 Fifth Avenue
                      New York, New York 10103
                      Attention: Neil Gold, Esq.

         Any of the foregoing may change its address for notices by notice to
the other parties.

             (d) Governing Law and Forum. The laws of the State of New York
         shall govern this Agreement, its construction, and the determination of
         any rights, duties or remedies of the parties arising out of, or
         relating to, this Agreement (regardless of the laws that might
         otherwise govern under applicable New York principles of conflicts of
         law). The parties acknowledge that the United States District Court for
         the Southern District of New York or the New York Supreme Court for the
         County of Columbia shall have exclusive jurisdiction over any case or
         controversy arising out of, or relating to, this Agreement and that all
         litigation arising out of, or relating to, this Agreement shall be
         commenced in the United States District Court for the Southern District
         of New York or in the Columbia County (New York) Supreme Court. Each of
         the parties consents to be subject to personal jurisdiction of the
         courts of New York, including the federal courts in New York.

             (e) Counterparts. This Agreement may be executed in two or more
         counterparts, each of which shall be deemed an original, but all of
         which together shall constitute one and the same instrument.

             (f) Interpretation. The Section headings contained in this
         Agreement are for the purposes of reference, are not part of the
         agreement of the parties and shall not in any way affect the meaning or
         interpretation of this Agreement.

             (g) Severability. If any provision of this Agreement is determined
         to be illegal or invalid, such illegality or invalidity shall have no
         effect on the other provisions of this Agreement, and all other
         provisions of this Agreement shall remain valid, operative and
         enforceable.

             (h) Assignment. The rights granted to the Placement Agents pursuant
         to this Agreement shall not be assignable without the written consent
         of the Company.



         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first written above.

                                                 AMERICAN BIO MEDICA CORPORATION

Exhibit 4.4  Form of Investor Warrant

EACH SUBSCRIBER SHALL RECEIVE A WARRANT CERTIFICATE AT CLOSING WITH THE TERMS
SET FORTH HEREIN, NOT A WARRANT IN THE FORM HEREUNDER. THIS FORM OF WARRANT IS
BEING PROVIDED TO EACH SUBSCRIBER SOLELY TO SET FORTH THE TERMS OF THE WARRANT

notify the holder hereof in writing), to purchase from the Company up to
_____________ shares of common stock, par value $0.01 per share ("Common
Stock"), of the Company (the "Warrant Shares") at the Exercise Price (defined
below), subject to adjustment as provided in Section 8 hereof.

         2.  Exercise Price. The purchase price for the Warrant Shares shall be
$1.05 per Warrant Share, as adjusted from time to time pursuant to Section 7
hereof (the "Exercise Price").

         3.  Exercise Period. This Warrant may be exercised at any time after
February 22, 2002 until 5:00 p.m., New York City time on the earlier of: (a)
August 22, 2006; or (b) upon redemption of this Warrant in accordance with the
terms and conditions set forth in Section 4 hereof.

         4.  Redemption. At any time after February 22, 2002 and prior to the
exercise of this Warrant:

             (a) On not less than twenty (20) days notice given at any time when
         the registration statement covering the resale of the shares of Common
         Stock issuable upon exercise of this Warrant required to be filed by



         the Company, pursuant to the registration rights agreement, dated as of
         the date hereof, by and among the Company and the persons signing the
         signature page thereof (the "Registration Rights Agreement"), is
         effective and which shall remain effective during such 20 day notice
         period, this Warrant may be redeemed, at the option of the Company, at
         a redemption price of $0.05, provided the closing price on the Nasdaq
         SmallCap Market or, if applicable, any automated quotation system or
         national securities exchange, of the Common Stock issuable upon
         exercise of this Warrant shall equal or exceed the then Exercise Price
         multiplied by three (3), for a period of twenty (20) consecutive
         trading days ending at least three (3) days prior to the date of the
         notice of redemption.

             (b) If the conditions set forth in Section 4(a) are met, and the
         Company elects to exercise its right to redeem this Warrant, it shall
         mail a notice of redemption to the registered Holder of this Warrant to
         be redeemed, first class, postage prepaid, not later than the thirtieth
         day before the date fixed for redemption, at their last address as
         shall appear on the records maintained by the Company. Any notice
         mailed in the manner provided herein shall be conclusively presumed to
         have been duly given whether or not the registered Holder receives such
         notice.

             (c) The notice of redemption shall specify (i) the redemption
         price, (ii) the date fixed for redemption, and (iii) that the right to
         exercise this Warrant shall terminate at 5:00 P.M. (New York time) on
         the business day immediately preceding the date fixed for redemption.
         The date fixed for the redemption of this Warrant shall be the
         "Redemption Date." No failure to mail such notice nor any defect
         therein or in the mailing thereof shall affect the validity of the
         proceedings for such redemption except as to a registered Holder (A) to
         whom notice was not mailed or (B) whose notice was defective. An
         affidavit of the Secretary or an Assistant Secretary of the Company
         that notice of redemption has been mailed shall, in the absence of
         fraud, be prima facie evidence of the facts stated therein.

             (d) Any right to exercise this Warrant shall terminate at 5:00 P.M.
         (New York time) on the business day immediately preceding the
         Redemption Date. On and after the Redemption Date, Holder of this
         Warrant shall have no further rights except to receive, upon surrender
         of the Warrant, the redemption price.

             (e) From and after the Redemption Date specified, the Company
         shall, at the place specified in the notice of redemption, upon
         presentation and surrender to the Company by or on behalf of the
         registered Holder thereof of one or more certificates evidencing this
         Warrant to be redeemed, deliver or cause to be delivered to or upon the
         written order of such Holder a sum in cash equal to the redemption
         price of this Warrant. From and after the Redemption Date and upon the
         deposit or setting aside by the Company of a sum sufficient to redeem
         this Warrant, this Warrant shall expire and become void and all rights
         hereunder, except the right to receive payment of the redemption price,
         shall cease.

         5.  Method of Exercise. While this Warrant remains outstanding and
exercisable in accordance with Section 3 above, the Holder may exercise, in
whole or in part, the purchase rights evidenced hereby. Such exercise shall be
effected by:

             (a) the surrender of the Warrant, together with a duly executed
         copy of the form of Notice of Exercise attached hereto, to the
         Secretary of the Company at its principal offices set forth on the
         signature page hereof; and



             (b) the payment in the form of a certified or bank cashier's check
         payable to the order of the Company in an amount equal to the Exercise
         Price multiplied by the number of Warrant Shares for which this Warrant
         is being exercised.

         6.  Certificates for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Warrant
Shares so purchased shall be issued as soon as practicable thereafter (with
appropriate restrictive legends, if applicable), and in any event within ten
(10) business days of the delivery of the Notice of Exercise.

         7.  Issuance of Shares. The Company covenants that the Warrant Shares,
when issued pursuant to the exercise of this Warrant, will be duly and validly
issued, fully paid and nonassessable and free from all taxes, liens, and charges
with respect to the issuance thereof.

         8.  Adjustment of Exercise Price and Kind and Number of Shares. The
number and kind of securities purchasable upon exercise of this Warrant and the
Exercise Price shall be subject to adjustment from time to time as follows:

             (a) Subdivisions, Combinations and Other Issuances. If the Company
         shall at any time prior to the expiration of this Warrant (i) subdivide
         its Common Stock, by split-up or otherwise, or combine its Common
         Stock, or (ii) issue additional shares of its Common Stock or other
         equity securities as a dividend with respect to any shares of its
         Common Stock; the number of shares of Common Stock issuable on the
         exercise of this Warrant shall forthwith be proportionately increased
         in the case of a subdivision (by stock split, stock dividend or
         otherwise), or proportionately decreased in the case of a combination.
         Appropriate adjustments shall also be made to the Exercise Price
         payable per share, but the aggregate Exercise Price payable for the
         total number of Warrant Shares purchasable under this Warrant (as
         adjusted) shall remain the same. Any adjustment under this Section 7(a)
         shall become effective at the close of business on the date the
         subdivision or combination becomes effective, or as of the record date
         of such dividend, or in the event that no record date is fixed, upon
         the making of such dividend.

             (b) Reclassification, Reorganization and Consolidation. In case of
         any reclassification, capital reorganization, or change in the Common
         Stock of the Company (other than as a result of a subdivision,
         combination, or stock dividend provided for in Section 8(a) above),
         then, as a condition of such reclassification, reorganization, or
         change, lawful provision shall be made, and duly executed documents
         evidencing the same from the Company or its successor shall be
         delivered to the Holder, so that the Holder shall have the right at any
         time prior to the expiration of this Warrant to purchase, at a total
         price equal to that payable upon the exercise of this Warrant (subject
         to adjustment of the Exercise Price as provided in Section 8), the kind
         and amount of shares of stock and other securities and property
         receivable in connection with such reclassification, reorganization, or
         change by a holder of the same number of shares of Common Stock as were
         purchasable by the Holder immediately prior to such reclassification,
         reorganization, or change. In any such case appropriate provisions
         shall be made with respect to the rights and interest of the Holder so
         that the provisions hereof shall thereafter be applicable with respect
         to any shares of stock or other securities and property deliverable
         upon exercise hereof, and appropriate adjustments shall be made to the
         purchase price per share payable hereunder, provided the aggregate
         Exercise Price shall remain the same.

             (c) Notice of Adjustment. When any adjustment is required to be
         made in the number or kind of shares purchasable upon exercise of the
         Warrant, or in the Exercise Price, the Company shall promptly notify
         the holder of such event and of the number of shares of Common Stock or
         other securities or property thereafter purchasable upon exercise of
         this Warrant.



             (d) Issuance of New Warrant. Upon the occurrence of any of the
         events listed in this Section 7 that results in an adjustment of the
         type, number or exercise price of the securities underlying this
         Warrant, the Holder shall have the right to receive a new warrant
         reflecting such adjustment upon the Holder tendering this Warrant in
         exchange. The new warrant shall otherwise have terms identical to this
         Warrant.

         9.  Covenants and Conditions.

             (a) No Impairment. Pursuant to the terms and conditions of this
         Warrant, Company shall: (i) reserve an appropriate number of shares of
         Company's Common Stock to facilitate the issuance of shares to Holder
         pursuant to this Warrant, (ii) not amend its articles or take any other
         action that would materially impair Company's ability to comply with
         the terms of the Warrant or otherwise unfairly impair the rights of the
         Holder, and (iii) provide Holder with at least 10 days prior written
         notice of the record date for any proposed dividend or distribution by
         the Company.

             (b) Registration Rights. The Company and Holder shall enter into
         the Registration Rights Agreement simultaneous with the execution of
         this Warrant on terms mutually agreeable to both parties.

         10. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant, but in lieu of such fractional shares the Company shall make a cash
payment therefor on the basis of the Exercise Price then in effect.

         11. No Stockholder Rights. Prior to exercise of this Warrant, the
Holder shall not be entitled to any rights of a stockholder with respect to the
shares of Common Stock issuable on the exercise hereof, including (without
limitation) the right to vote such shares of Common Stock, receive dividends or
other distributions thereon, exercise preemptive rights or be notified of
stockholder meetings, and such holder shall not be entitled to any notice or
other communication concerning the business or affairs of the Company. However,
nothing in this Section 11 shall limit the right of the Holder to be provided
the notices required under this Warrant.

         12. Successors and Assigns. The terms and provisions of this Warrant
shall inure to the benefit of, and be binding upon, the Company and the Holder
and their respective successors and assigns.

         13. Amendments and Waivers. Any term of this Warrant may be amended and
the observance of any term of this Warrant may be waived (either generally or in
a particular instance and either retroactively or prospectively), with the
written consent of the Company and the Holder. Any waiver or amendment effected
in accordance with this Section shall be binding upon each holder of any shares
of Common Stock purchased under this Warrant at the time outstanding (including
securities into which such shares have been converted), each future holder of
all such Shares, and the Company.

         14. Notices. All notices required under this Warrant and shall be
deemed to have been given or made for all purposes (i) upon personal delivery,
(ii) upon confirmation receipt that the communication was successfully sent to
the applicable number if sent by facsimile; (iii) one day after being sent, when

when sent by registered or certified mail. Notices to the Company shall be sent
to the principal office of the Company (or at such other place as the Company
shall notify the Holder hereof in writing). Notices to the Holder shall be sent
to the address of the Holder on the books of the Company (or at such other place
as the Holder shall notify the Company hereof in writing).



         15. Attorneys' Fees. If any action of law or equity is necessary to
enforce or interpret the terms of this Warrant, the prevailing party shall be
entitled to its reasonable attorneys' fees, costs and disbursements in addition
to any other relief to which it may be entitled.

         16. Captions. The section and subsection headings of this Warrant are
inserted for convenience only and shall not constitute a part of this Warrant in
construing or interpreting any provision hereof.

         17. Governing Law. This Warrant shall be governed by the laws of the

         price of this Warrant. From and after the Redemption Date and upon the
         deposit or setting aside by the Company of a sum sufficient to redeem
         this Warrant, this Warrant shall expire and become void and all rights
         hereunder, except the right to receive payment of the redemption price,

             number of Warrant Shares for which this Warrant is being exercised;
             or



                 in lieu of any cash payment, the Holder of the Warrants shall
             have th right at any time and from time to time to exercise the
             Warrants in full or in part by surrendering the Warrant in exchange
             for the number of shares equal to the product of (x) the number of
             shares as to which the Warrants are being exercised multiplied by
             (y) a fraction, the numerator of which is the Market Price, (as
             defined below) of the Shares less the Exercise Price and the
             denominator of which is such Market Price. Solely for the purposes
             of this paragraph, "Market Price" shall be the average last
             reported sale price of the Common Shares as calculated over the
             five (5) trading day period preceding the date on which the
             Election to Purchase is surrendered to the Company.

         6.  Certificates for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Warrant
Shares so purchased shall be issued as soon as practicable thereafter (with
appropriate restrictive legends, if applicable), and in any event within ten
(10) business days of the delivery of the Notice of Exercise.

         7.  Issuance of Shares. The Company covenants that the Warrant Shares,
when issued pursuant to the exercise of this Warrant, will be duly and validly
issued, fully paid and nonassessable and free from all taxes, liens, and charges
with respect to the issuance thereof.

         8.  Adjustment of Exercise Price and Kind and Number of Shares. The
number and kind of securities purchasable upon exercise of this Warrant and the
Exercise Price shall be subject to adjustment from time to time as follows:

             (a) Subdivisions, Combinations and Other Issuances. If the Company
         shall at any time prior to the expiration of this Warrant (i) subdivide
         its Common Stock, by split-up or otherwise, or combine its Common
         Stock, or (ii) issue additional shares of its Common Stock or other
         equity securities as a dividend with respect to any shares of its
         Common Stock; the number of shares of Common Stock issuable on the
         exercise of this Warrant shall forthwith be proportionately increased
         in the case of a subdivision (by stock split, stock dividend or
         otherwise), or proportionately decreased in the case of a combination.
         Appropriate adjustments shall also be made to the Exercise Price
         payable per share, but the aggregate Exercise Price payable for the
         total number of Warrant Shares purchasable under this Warrant (as
         adjusted) shall remain the same. Any adjustment under this Section 7(a)
         shall become effective at the close of business on the date the
         subdivision or combination becomes effective, or as of the record date
         of such dividend, or in the event that no record date is fixed, upon
         the making of such dividend.

             (b) Reclassification, Reorganization and Consolidation. In case of
         any reclassification, capital reorganization, or change in the Common
         Stock of the Company (other than as a result of a subdivision,
         combination, or stock dividend provided for in Section 8(a) above),
         then, as a condition of such reclassification, reorganization, or
         change, lawful provision shall be made, and duly executed documents
         evidencing the same from the Company or its successor shall be
         delivered to the Holder, so that the Holder shall have the right at any
         time prior to the expiration of this Warrant to purchase, at a total
         price equal to that payable upon the exercise of this Warrant (subject
         to adjustment of the Exercise Price as provided in Section 8), the kind
         and amount of shares of stock and other securities and property
         receivable in connection with such reclassification, reorganization, or
         change by a holder of the same number of shares of Common Stock as were
         purchasable by the Holder immediately prior to such reclassification,
         reorganization, or change. In any such case appropriate provisions
         shall be made with respect to the rights and interest of the Holder so
         that the provisions hereof shall thereafter be applicable with respect
         to any shares of stock or other securities and property deliverable
         upon exercise hereof, and appropriate adjustments shall be made to the
         purchase price per share payable hereunder, provided the aggregate
         Exercise Price shall remain the same.



             (c) Notice of Adjustment. When any adjustment is required to be
         made in the number or kind of shares purchasable upon exercise of the
         Warrant, or in the Exercise Price, the Company shall promptly notify
         the holder of such event and of the number of shares of Common Stock or
         other securities or property thereafter purchasable upon exercise of
         this Warrant.

             (d) Issuance of New Warrant. Upon the occurrence of any of the
         events listed in this Section 7 that results in an adjustment of the
         type, number or exercise price of the securities underlying this
         Warrant, the Holder shall have the right to receive a new warrant
         reflecting such adjustment upon the Holder tendering this Warrant in
         exchange. The new warrant shall otherwise have terms identical to this
         Warrant.

         9.  Covenants and Conditions.

             (a) No Impairment. Pursuant to the terms and conditions of this
         Warrant, Company shall: (i) reserve an appropriate number of shares of
         Company's Common Stock to facilitate the issuance of shares to Holder
         pursuant to this Warrant, (ii) not amend its articles or take any other
         action that would materially impair Company's ability to comply with
         the terms of the Warrant or otherwise unfairly impair the rights of the
         Holder, and (iii) provide Holder with at least 10 days prior written
         notice of the record date for any proposed dividend or distribution by
         the Company.

             (b) Registration Rights. The Company and Holder shall enter into
         the Registration Rights Agreement simultaneous with the execution of
         this Warrant on terms mutually agreeable to both parties.

         10. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant, but in lieu of such fractional shares the Company shall make a cash
payment therefor on the basis of the Exercise Price then in effect.

         11. No Stockholder Rights. Prior to exercise of this Warrant, the
Holder shall not be entitled to any rights of a stockholder with respect to the
shares of Common Stock issuable on the exercise hereof, including (without
limitation) the right to vote such shares of Common Stock, receive dividends or
other distributions thereon, exercise preemptive rights or be notified of
stockholder meetings, and such holder shall not be entitled to any notice or
other communication concerning the business or affairs of the Company. However,
nothing in this Section 11 shall limit the right of the Holder to be provided
the notices required under this Warrant.

         12. Successors and Assigns. The terms and provisions of this Warrant
shall inure to the benefit of, and be binding upon, the Company and the Holder
and their respective successors and assigns.

         13. Amendments and Waivers. Any term of this Warrant may be amended and
the observance of any term of this Warrant may be waived (either generally or in
a particular instance and either retroactively or prospectively), with the
written consent of the Company and the Holder. Any waiver or amendment effected
in accordance with this Section shall be binding upon each holder of any shares
of Common Stock purchased under this Warrant at the time outstanding (including
securities into which such shares have been converted), each future holder of
all such Shares, and the Company.



         14. Notices. All notices required under this Warrant and shall be
deemed to have been given or made for all purposes (i) upon personal delivery,
(ii) upon confirmation receipt that the communication was successfully sent to
the applicable number if sent by facsimile; (iii) one day after being sent, when
sent by professional overnight courier service, or (iv) five days after posting
when sent by registered or certified mail. Notices to the Company shall be sent
to the principal office of the Company (or at such other place as the Company
shall notify the Holder hereof in writing). Notices to the Holder shall be sent
to the address of the Holder on the books of the Company (or at such other place
as the Holder shall notify the Company hereof in writing).

         15. Attorneys' Fees. If any action of law or equity is necessary to
enforce or interpret the terms of this Warrant, the prevailing party shall be
entitled to its reasonable attorneys' fees, costs and disbursements in addition
to any other relief to which it may be entitled.

         16. Captions. The section and subsection headings of this Warrant are
inserted for convenience only and shall not constitute a part of this Warrant in
construing or interpreting any provision hereof.

         17. Governing Law. This Warrant shall be governed by the laws of the
State of New York, without regard to the provisions thereof relating to conflict
of laws.

to be executed by an officer thereunto duly authorized.
