                                     PART I

ITEM 1.           DESCRIPTION OF BUSINESS

Introduction

         Avitar, Inc. (the "Company" or "Avitar") through its wholly-owned
subsidiary Avitar Technologies, Inc. ("ATI") develops, manufactures, markets and
sells diagnostic test products and proprietary hydrophilic polyurethane foam
disposables fabricated for medical, diagnostics, dental and consumer use. During
the past year, the Company completed the development and began marketing
innovative point of care oral fluid drugs of abuse tests, which use the
Company's foam as the means for collecting the oral fluid sample.

         On July 9, 1999, the Company completed its acquisition of United States
Drug Testing Laboratories, Inc. ("USDTL"), which became a wholly-owned
subsidiary of Avitar. USDTL operates a certified laboratory and provides
specialized drug testing services primarily utilizing hair as the sample.

         On October 27, 1997, the Company sold the business and assets of its
wholly-owned subsidiary, Managed Health Benefits Corporation ("MHB"), which
provided health care cost containment services. Therefore, MHB is considered a
discontinued operation and this report primarily reflects the continued
operations of the Company.

Products

         Currently, the Company offers the following products, which utilize its
proprietary medical polyurethane foam technology:

         Diagnostic Test Products

         The Company makes products and offers services for the diagnostic test
applications described below. These products accounted for approximately 22% of
the Company's revenue in Fiscal 1999 and approximately 8% of the Company's
revenue in Fiscal 1998.

         Drugs of Abuse Test Kits. Under a joint development agreement with Sun
Biomedical Laboratories ("SBL") of Cherry Hill, New Jersey, the Company
completed the development of OralScreen 3(Trademark), an oral fluid-based rapid
on-site assay system for detecting drugs of abuse (heroin, cocaine and
marijuana) in the workplace. In addition, the Company is currently developing
similar tests to include other drugs of abuse. Approximately $1 billion annually
is spent worldwide for drugs of abuse tests.

                                                                               3
<PAGE>

Significant advantages exist for saliva to replace blood and urine in many of
these tests and at the same time expand the market where current infrastructure
cost limitations prohibit the use of much needed diagnostic tests. Using its
Oral Fluid Sampling and Processing System, the Company has entered into this
large and growing market for testing for drugs of abuse.

         Drugs of Abuse Laboratory Tests. The Company's HairScreen(Trademark), a
hair-based test, can detect both short and long-term (90 days and beyond) drug
abuse. The Child Guard(Trademark) tests provide the ability to detect a child's
exposure to drugs and possible drug abuse through testing of a child's hair. In
addition, the MecStat testing services offer highly specialized testing to
detect in utero exposure to alcohol and other drugs of abuse in newborns.

         Foam Disposable Products

         The Company produces medical-grade hydrophilic polyurethane foam
disposables fabricated for the applications described below. These products
accounted for approximately 78% of the Company's revenue in Fiscal 1999 and
approximately 92% of the Company's revenue in Fiscal 1998.

         Wound Dressings. Avitar's Hydrasorb(Trademark) ("Hydrasorb") wound
dressing product is a highly absorbent topical dressing for moderate to heavy
exudating wounds. These dressings have a unique construction that provide a
moist wound healing environment which promotes skin growth and closure. The
Hydrasorb product is marketed internationally by the ConvaTec Division of
Bristol-Myers Squibb ("Convatec") (until December 31, 1999), by the Knoll Pharma
Division of BASF ("Knoll") and other specialty distributors worldwide. Effective
January 1, 2000, the Hydrasorb product will be marketed in the United States by
the Kendall Company ("Kendall"). In addition to the Hydrasorb line, the Company
has custom developed specialty wound dressings for the cardiac catheter lab
market as well as the orthopedic market. The Joyce Dressing is used in dressing
the introducer catheter for cardiology procedures and is marketed directly by
Avitar. The market in the United States and Europe for synthetic dressings is
estimated at $1.2 billion annually with foam dressings accounting for
approximately $150 million. New foam applications are currently being evaluated
by the Company to broaden this product line. Currently under development are a
number of second-generation wound dressings, which combine the Company's
hydrophilic polyurethane foam with other biomaterials for composite dressings.

         Custom Foam Products. The Company continues to expand the number of
applications for its proprietary technologies in a variety of other
medical/consumer markets. They include the Illizarov Dressing used for dressing
external bone fixators in orthopedic procedures and a molded dental applicator
for a consumer teeth bleaching system and disposable ear cushions for a
high-tech hearing aid device. Customers for these products include Smith and
Nephew, CCA Industries, Deaconess Hospital, Decibel Instruments and Schleicher
and Schuell.

                                                                               4
<PAGE>

Development

         The Company does not conduct pure research activities but has adopted a
primary product development strategy that is based on forming partnerships with
market leading companies and recognized persons or entities in diagnostic
testing and foam products application areas. With this approach, proprietary
products would be co-developed through the generation and development of product
ideas either internally or through these strategic partnerships. To this
partnership, Avitar contributes the proprietary foam technology and related
expertise, the product design, development and prototyping, and the start-up and
commercial-scale manufacturing. The ability of the Company to keep current on
technology and purchase new equipment in connection with development of new,
improved products will be affected by its existing and future need for, and the
availability of, financing.

         Products go through several stages of development. After each stage,
the Company will conduct studies to determine the effectiveness of such product.
Once a product is developed and the Company determines it may be commercially
viable, Avitar will obtain governmental approvals, if necessary, prior to
marketing the product. See "Government Regulation." There can be no assurance,
however, that such approvals will actually be obtained. The Company intends to
conduct marketing trials with any new product to determine the effectiveness of
the product. If such marketing trials prove to be successful and after the
product is ready for marketing, Avitar will attempt to establish an arrangement
with a known company or individual with established distribution channels, most
likely with the same research and development partner, to commercially
distribute the new product. For certain products and services such as the tests
for drugs of abuse, the Company may decide to establish a distribution network
or directly market and distribute these products. See "Sales and Marketing"
below.

         Avitar currently employs seven full-time individuals in its development
efforts. In addition, one other employee also devotes a portion of his time to
development, as well as to the manufacture of the Company's products, quality
control, regulatory affairs and facility maintenance.

Sales and Marketing

         The Company generally has sold, and intends to continue to sell, its
wound dressing and custom foam products through large, recognized distributors
of dental and medical products and does not anticipate that a large direct sales
force will be required. To sell its OralScreen(Trademark) test kits, the Company
is developing a network of established distributors that currently sell to the
drugs of abuse test kit market. For the HairScreen(Trademark), Child
Guard(Trademark), and MecStat services, the Company sells these services
directly to end

                                                                               5
<PAGE>

users such as employers and through the distributor network being established
for the OralScreen(Trademark) products. Avitar's sales and marketing staff
consists of eight full-time employees. If the Company is unable to establish
satisfactory product distribution arrangements in this manner described above,
it will be required to devote substantial resources to the establishment of a
direct sales force. There can be no assurance that Avitar would have the
resources required for such an endeavor. The Company also intends to develop
strategic partnering arrangements with significant diagnostic test, health care
and dental companies with established distribution channels. Avitar anticipates
that such arrangements may involve the grant by Avitar of the exclusive or
semi-exclusive rights to sell specific products to specified market segments
and/or in particular geographic territories in exchange for a royalty, joint
venture or other financial interest.

         To introduce its products to targeted distributors and direct
customers, the Company participates in trade shows and conducts seminars for
sales personnel. Avitar also conducts user trials to support the marketing
efforts of its distribution partners.

         The Company believes that these arrangements will be more effective in
promoting and distributing its products in view of Avitar's limited resources
and the extensive marketing networks of such distributors.

         The Company's most significant distribution arrangements are summarized
as follows:

         Oral Fluids Sampling and Processing Systems. In March 1996, the Company
signed a licensing agreement with Simplex Medical Systems, Inc. ("Simplex"),
which grants Avitar exclusive worldwide rights to manufacture and market
Simplex's patent-pending, state-of-the-art saliva collection device. This
device, which utilizes Avitar's proprietary foam technology, will be used to
collect saliva for diagnostic tests such as HIV, hepatitis, and a number of
other diseases and substances which formerly required blood as the test medium.
Under this licensing agreement, the Company must pay to Simplex certain
royalties on the sale of each licensed product.

         Drugs of AbuseTest Kits. Under a development agreement signed in
February 1999, Avitar and SBL developed OralScreen3(Trademark) described above
under Products and are currently developing new oral fluid-based rapid screening
tests for additional drugs of abuse. These tests use the Company's proprietary
oral fluid collection system with Avitar having the exclusive, world-wide
manufacturing and distribution rights to the tests.

         Wound Dressings. In June 1992, Avitar granted Medi the right to sell
Avitar's wound care products in Germany for a period of one year. Although the
agreement, by its terms, expired in June 1993, Avitar and Medi have continued
the relationship under the terms and conditions of the original agreement.
Prices of products sold to Medi may be changed upon 60 days notice. Medi is a
privately owned distributor and producer of medical products based in Bayreuth,
Germany, and sells medical products in 20 countries.

                                                                               6
<PAGE>

It distributes products through its direct specialty sales force and distributes
Avitar's product on a private label basis.

         Since November 1993, the Company has maintained a distribution
agreement with Knoll (the "Knoll Agreement") pursuant to which Knoll was granted
the right to distribute Hydrasorb(Trademark) products throughout Canada. The
Knoll Agreement provides that Hydrasorb(Trademark) products are to be sold at
agreed upon prices (subject to annual inflation adjustments) and that certain
minimum quantities are maintained.

         In December 1999, the Company entered into a Supply Agreement with the
Kendall Company for the distribution of its Hydrasorb(Trademark) products in the
United States beginning January 1, 2000. Kendall replaces Convatec as the
distributor for these products in the United States.

         Custom Foam Products. Custom medical foam products (including the
Illizarov dressing and certain nasal and sinus products) are marketed and
distributed (in the United States and abroad) primarily by Smith & Nephew on a
non-exclusive basis pursuant to an oral agreement.

Manufacturing and Supply.

           The Company's only manufacturing facility is located in Canton,
Massachusetts and comprises approximately 53,000 square feet of which 8,000
square feet is currently being used for administrative and office space and
31,000 square feet is being used for product manufacturing and warehousing.
Since the remaining 14,000 square feet is not being used at this time and will
not be needed for the next several years, ATI has subleased approximately 6,000
square feet and is attempting to sub-lease the other 8,000 square feet.

         Given the use of Avitar's products in the diagnostic test, medical and
dental markets, the Company is required to conform to FDA Good Manufacturing
Practice regulations, International Standard Organization ("ISO") rules and
various other statutory and regulatory requirements applicable to the
manufacture and sale of medical devices. Avitar is subject to inspections by the
FDA at all times. Avitar believes that its facilities and procedures are in
compliance with these requirements. See "Government Regulation".

         The Company does not have written agreements with most of its suppliers
of raw materials and laboratory supplies. While the Company purchases some
product components from single sources, most of the laboratory supplies used by
USDTL can be obtained from more than one source. Avitar acquires the same key
component for its Flureze(Trademark) fluoride application product, customized
foam products and Hydrasorb(Trademark) wound dressings from a single supplier.
The Company also purchases main components of its OralScreen(Trademark) products
from a single source. Avitar's current suppliers of such key components are the
only vendors, which presently meet Avitar's specifications for such

                                                                               7
<PAGE>

components. The loss of these suppliers would, at a minimum, require the Company
to locate other satisfactory vendors, which would result in a period of time
during which manufacturing and sales of products utilizing such a components may
be suspended and could have a material adverse effect on Avitar's financial
condition and operations. Avitar believes that alternative sources could be
found for such key components and expects that the cost of such components from
an alternative source would be similar. The Company also believes that
alternative sources of supply are available for its remaining product components
and that the loss of any such supplier would not have a material adverse effect
upon Avitar's business.

Government Regulation

           Avitar and many of its products are subject to regulation by the FDA
and the corresponding agencies of the states and foreign countries in which the
Company sells its products. Accordingly, the Company is required to comply with
applicable FDA regulations, ISO rules and similar other state and foreign
country requirements governing the manufacture, marketing, distribution,
labeling, registration, notification, clearance and/or pre-market approval of
drugs, medical and dental devices and cosmetics, as well as record keeping and
reporting requirements applicable to such products. The Company believes that it
is in compliance with all such requirements. In addition, the Company is subject
to inspections by the FDA at all times, and may be subject to inspections by
state and foreign agencies. If the FDA believes that its legal requirements have
not been fulfilled, it has extensive enforcement powers, including the ability
to initiate action to physically seize products or to enjoin their manufacture
and distribution, to require recalls of certain types of products, and to impose
or seek to impose civil or criminal sanctions against individuals or companies
violating applicable statutes.

         The standards and procedures for obtaining approval or providing
notification to the FDA with respect to medical devices were changed by
legislation in1990. This legislation, which also affected numerous other changes
in device regulations, is still being interpreted and implemented by the FDA. In
addition, there can be no assurance that the FDA or the U.S. Federal Government
will not enact further changes in the current rules and regulations with respect
to products, which Avitar already markets or may plan to market in the future.
If Avitar is unable to demonstrate compliance with such new or modified
requirements, sales of affected products may be significantly limited or
prohibited until such requirements are met (if ever).

Competition

         The Company believes that the principal competitive factors in Avitar's
markets are innovative product design, product quality, established customer
relationships, name recognition, distribution and price. Many companies of all
sizes, including major diagnostic test, dental and health care companies, are
engaged in activities similar to those of Avitar. Most of Avitar's competitors
have substantially greater financial, marketing, administrative and other
resources and larger research and development staffs.

                                                                               8
<PAGE>

         Although Avitar may not have the development resources of many of its
competitors, the Company believes its product design and development experience
allows it to compete favorably in providing innovative products and services in
Avitar's markets. Avitar's OralScreen(Trademark) products are the only oral
fluid drugs of abuse tests currently being marketed in the United States and
USDTL's HairScreen(Trademark), ChildGuard(Trademark) and MecStat services
represent comprehensive, state-of-the-art tests for drugs of abuse currently
being provided in the United States and South America. Furthermore, the Company
believes that its Hydrasorb(Trademark) wound dressings, and custom foam products
possess qualities with significant advantages over competing products, including
cost effectiveness. Although the Company does not have an established internal
distribution network, Medi, Knoll and Kendall are distributing the Company's
Hydrasorb(Trademark) wound dressings while Armor Holdings, CMI, Edwards Medical
and many smaller, local companies are distributing the Company's
OralScreen(Trademark) products. See "Products", "Sales and Marketing".

         In addition, colleges, universities, governmental agencies and other
public and private research organizations will continue to conduct research and
are becoming more active in seeking patent protection and licensing arrangements
to collect royalties for use of technology that they have developed, some of
which may be directly competitive with that of Avitar. In addition, these
institutions compete with companies such as Avitar in recruiting highly
qualified scientific personnel.

         The Company believes that its product markets are highly fragmented
with many different companies competing with regard to a specific product or
product category. As a result, Avitar's competition varies from product to
product. Avitar's primary competitors in the wound dressing market include
Squibb, Johnson & Johnson, Smith and Nephew, 3M and Acme United. In the drugs of
abuse test market, the largest competitors are Roche Diagnostic Systems, Biosite
Diagnostics, Editek, Inc., Princeton Biomedical, American Biomedical and
Psychemetics.

Intellectual Property

         Trade secrets, proprietary information and know-how are important to
the Company's scientific and commercial success. Avitar currently relies on a
combination of patents, trade secrets, trademark law and non-disclosure
agreements to establish and protect its proprietary rights in its products.
Avitar currently holds numerous United States patents, has applications pending
for additional patents and has licenses to use certain patents. In addition, the
Company has certain registered and other trademarks.

         The Company believes that its products, trademarks and other
proprietary rights do not infringe upon the proprietary rights of third parties.

                                                                               9
<PAGE>

Product Liability; Insurance Coverage

         The testing, marketing and sale of diagnostic test, medical and dental
products and services entail a high risk of product liability and professional
liability claims by consumers and others. Claims may be asserted against the
Company by end-users of any of Avitar's products. As of September 30, 1999, the
Company had product liability insurance coverage in the amount of $5,000,000 and
professional liability insurance coverage in the amount of $1,000,000 each
incident and $3,000,000 in the aggregate. No claims had been asserted against
either coverage. Amounts payable pursuant to such coverage are subject to a
deductible on each occurrence ranging from $500 to $5,000 payable by Avitar, up
to an annual aggregate deductible payable by Avitar of $25,000, and certain
other coverage exclusions. This insurance will not cover liabilities caused by
events occurring prior to the time such policy was purchased by the Company or
liabilities caused by events occurring after such policy is terminated or for
claims made after 60 days following termination of the policy. Further, certain
distributors of diagnostic test, medical and dental products require minimum
product liability insurance coverage as a condition precedent to purchasing or
accepting products for distribution.

Employees

         At September 30, 1999, the Company had 55 full-time employees,
including 7 in research and development (in addition to one other employee who
devotes a portion of his time to research and development as well as
manufacturing and supply activities), 30 in manufacturing, supply and laboratory
operations (one of whom devotes a portion of his time to research and
development), 8 in sales and marketing and 10 in administration. None of the
employees is subject to a collective bargaining agreement. The Company believes
its relationship with its employees to be satisfactory.

ITEM 2.           DESCRIPTION OF PROPERTY

         The Company leases approximately 57,000 square feet (53,000 square feet
in Canton, Massachusetts for its manufacturing facility and administrative
offices and 4,000 square feet in DesPlaines, Illinois for the laboratory
operation of USDTL). The current annual rent for the Canton facility (excluding
assessment for operating expenses) is approximately $455,000 and the lease
expires in June 2005. The lease for the DesPlaines facility expired in November
1999 and a new lease covering approximately 8,000 square feet at the same
location is currently being negotiated. Both facilities are in satisfactory
condition for their pruposes.

ITEM 3.           LEGAL PROCEEDINGS.

         In August 1996, A.S. Goldmen & Co., Inc. (the "Underwriter") and
certain holders of Underwriter's warrants issued by the Company commenced a
court action against the Company by filing a complaint in Federal Court for the
Southern District of New York (the "Court"), seeking, among other things,
damages of $6,261,839.00 based upon the Underwriters' warrant agreement between
the Company and the Underwriter.

                                                                              10
<PAGE>

         The monetary demands made by the Underwriter relate primarily to the
anti-dilution provision of the warrant agreement. The Company believes that the
Underwriter's claims improperly sought additional underwriting compensation in
defiance of NASD rules that proscribe underwriters and their associates from
receiving the kind of compensation sought - based on the type of anti-dilution
provision invoked by the Underwriter on the ground that it is unfair and
unreasonable. The Company immediately moved to dismiss the Underwriter's
complaint based upon both the rule violations and otherwise. In December 1998,
the Court denied the Company's motion to dismiss the Underwriter's complaint,
but did not decide and expressly left open for a later day the principal legal
argument urged by the Company in favor of dismissal. In March 1999, this action
was settled and discontinued with prejudice. In connection with the settlement,
the company issued 400,000 shares of common stock.

         In 1997, former attorneys for the Company commenced an action (and made
a motion for summary judgment) against the Company in New York Supreme Court.
This proceeding was based on a note given by the Company in connection with such
former attorneys' claim for legal fees. Plaintiff sought judgment in the
principal amount of $185,171.63 plus the accrued interest thereon. Plaintiff
commenced action on February 27, 1997 but, with extensions, the Company
responded in opposition on June 13, 1997 and, after service of the plaintiff's
reply, the motion was submitted to the Court on June 26, 1997. In November 1997,
the Company reached a settlement with the plaintiff whereby the Company paid
$90,000 in cash and issued 275,000 shares of its common stock.

         Dividends. Since its inception, the Company has not paid or declared
any cash dividends on its Common Stock. The Company intends to retain future
earnings, if any, that may be generated from its operations to help finance the
operations and expansion of the Company and accordingly does not plan, for the
reasonably foreseeable future, to pay cash dividends to holders of its Common
Stock. Any decisions as to the future payment of dividends will depend on the
earnings, if any, and financial position of the Company and such other factors
as its Board of Directors may deem relevant.

         Sales of Unregistered Securities. During the quarter ended September
30, 1999, the Company issued 2,062,570 shares of the Company's common stock as
compensation for the acquisition of USDTL. In addition, the Company issued
352,760 shares in connection with the exercise of warrants and services provided
to the Company for which it received proceeds of approximately $87,000. The
exemption for registration of these securities is based on Section 4(2) of the
Securities Act.

ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

         The following discussion and analysis should be read in conjunction
with the Company's consolidated financial statements and the notes thereto
appearing elsewhere in this report.

Results of Operations

Revenues

         Sales for the fiscal year ended September 30, 1999 ("Fiscal 1999")
increased $291,777 or approximately 13% to $2,495,423 from $2,203,646 for the
fiscal year ended September 30, 1998 ("Fiscal 1998"). The results for Fiscal
1999 primarily reflect the increase in sales of drug of abuse testing kits and
services of approximately $399,000 (including revenues from USDTL of
approximately $245,000); offset in part by a decrease in the sales of the wound
dressing products of approximately $107,000.

Operating Expenses

         Costs of sales were approximately 83% of sales in Fiscal 1999 compared
to approximately 87% of sales for Fiscal 1998. The lower ratio of cost to sales
for Fiscal 1999 was primarily related to the increase in sales described above
and the change in the product mix.

         Sales, general and administrative expenses for Fiscal 1999 increased
$1,143,354 or approximately 75%, to $2,673,415 from $1,530,061 for Fiscal 1998.
This increase resulted mainly from expanded sales, marketing and administrative
efforts associated with the Company's launching of its OralScreen(Trademark)
products of approximately $1,000,000 and USDTL's selling, general and
administrative expenses of approximately $171,000.

                                                                              13
<PAGE>

         Research and development expenses for Fiscal 1999 amounted to $792,211
compared to $546,233 for Fiscal 1998. The increase of $245,978, or approximately
45%, was primarily attributable to increased research and development activities
related to the Company's OralScreen(Trademark) products.

         For Fiscal 1999, amortization of goodwill of $70,424 was recorded in
connection with the Company's acquisition of USDTL compared to no amortization
of goodwill in Fiscal 1998.

Other Income and Expense

         Interest income amounted to $30,273 for Fiscal 1999 compared to $8,126
for Fiscal 1998. This increase resulted primarily from the interest earned on
cash management accounts and on the notes receivable from investors in
connection with the Company's sales of Series B Redeemable Convertible Preferred
Stock.

         Interest expense and financing costs were $121,572 for Fiscal 1999
compared to $135,398 incurred during Fiscal 1998. This decrease resulted
primarily from reduced interest expense on loans from banks and related parties.

         Other income amounted to $73,729 for Fiscal 1999 versus other income of
$25,965 for Fiscal 1998. This change mainly reflects rental income from the
Company subleasing excess square feet in its facility to a major department
store chain and a software maintenance company.

Discontinued Operations

         In October 1997, the Company consummated the sale of the net assets and
business of its MHB subsidiary and received $1,286,000. No income or expenses
from this subsidiary were recorded in Fiscal 1999 compared to income from
operations and sale of MHB of $1,136,170 in Fiscal 1998.

Net Loss

         Primarily as a result of the factors described above, the Company had a
net loss of $3,117,680 for Fiscal 1999 compared to a net loss of $757,954 for
Fiscal 1998.

Financial Condition and Liquidity

         At September 30, 1999 and September 30, 1998, the Company had working
capital deficiencies of $738,755 and $1,569,085, respectively, and cash and cash
equivalents of $280,758 and $12,483, respectively. Net cash used in operating
activities during Fiscal 1999 amounted to $3,346,604 resulting primarily from
the operating loss of $3,117,680, an increase in accounts receivable of
$108,051, increases in inventories and

                                                                              14
<PAGE>

prepaid expenses of $91,068 and an increase in other assets of $327,627;
partially offset by depreciation and amortization of $121,112, amortization of
goodwill of $70,424 and non-cash charges for services and compensation of
$28,746 and increases in accounts payable and accrued expenses of $77,540. Net
cash provided by financing and investing activities during Fiscal 1999 was
$3,614,879 which included proceeds from the sale of preferred stock and warrants
of $2,959,832, proceeds from the exercise of options and warrants of $888,282
and proceeds, net of cash acquired, from the acquisition of USDTL of $11,882;
offset in part by re-payment of notes payable and long-term debt of $175,938 and
purchases of property and equipment of $69,179.

         During the period of Fiscal 1999, the Company received net proceeds of
approximately $3,658,300 ($2,959,832 in cash and $698,468 in notes receivable)
from the sale of 1,542,966 shares of Series B Convertible Preferred Stock
(convertible at any time into 15,429,660 shares of the Company's common stock)
which included warrants to purchase 7,386,600 shares of the Company's common
stock at exercise prices of approximately $.225-2.39 per share for periods of
twelve to thirty-six months. From February through September 1999, the Company
received net proceeds of approximately $888,282 from the exercise of warrants
and stock options to purchase approximately 2,300,650 shares of the Company's
common stock. In March 1999, both the Chairman of the Board and the President of
the Company converted notes payable (including the accrued interest thereon) and
accrued salaries totaling $200,000 into 24,570 shares of the Company's Series B
convertible preferred stock (convertible into 245,700 shares of the Company's
common stock) and warrants to purchase 400,000 shares of the Company' s common
stock at an exercise price of $1.22 per share for one year. During the period of
October through early January 2000, the Company received net proceeds of
$2,402,000 from the sale of 400,333 shares of Series C convertible preferred
stock and approximately $196,000 from the exercise of warrants to purchase
approximately 427,000 shares of the Company's common stock. From January 2000 to
April 2000, the Company expects to receive proceeds of approximately $3,000,000
to $4,000,000 from the exercise of warrants issued in connection with the sale
of the Series B convertible preferred stock. Currently, all such warrants are in
the money. In addition, the Company is actively attempting to raise up to
$3,000,000 from the sales of equity securities to provide working capital and
capital equipment funding to operate the Company, expand the Company's business
and to pursue the development of oral fluid diagnostic testing for disease.
However, there can be no assurance that these financings will be achieved or
that the warrants will be exercised.

         For the balance of fiscal year 2000, the Company's cash requirements
are expected to include primarily the funding of operating losses, the payment
of outstanding accounts payable, the repayment of certain notes payable, the
funding of operating capital to grow the Company's drugs of abuse testing
products and services and the initial funding for the development of oral fluid
diagnostic testing products for diseases.

         Although operating revenues (exclusive of revenues from USDTL of
$245,000) of the Company rose only 2% in Fiscal 1999, sales are expected to grow
at a more rapid

                                                                              15
<PAGE>

pace during Fiscal 2000 as the Company continues to increase the shipments of
its OralScreen(Trademark) products and expands the business of USDTL. Based on
current sales, expense and cash flow projections, the Company believes that the
current level of cash and short-term investments on hand and a portion of the
anticipated net proceeds from the financing mentioned above would be sufficient
to fund operations until the Company achieves profitability. There can be no
assurance that the Company will consummate the above-mentioned financing, or
that any or all of the net proceeds sought thereby will be obtained. Once the
Company achieves profitability, the longer-term cash requirements of the Company
to fund operating activities, purchase capital equipment, expand the existing
business and develop new products are expected to be met by the anticipated cash
flow from operations and proceeds from the financings described above. However,
because there can be no assurances that sales will materialize as forecasted,
management will continue to closely monitor and attempt to control costs at the
Company and will continue to actively seek the needed additional capital.

Year 2000 Impact

         Many currently installed computer systems and software products are
coded to accept or recognize only two digit entries in the date code field.
These systems and software products will need to accept four digit entries to
distinguish 21st century dates from 20th century dates. As a result, computer
systems and/or software used by many companies and governmental agencies may
need to be upgraded to comply with such Year 2000 requirements or risk system
failure or miscalculations causing disruptions of normal business activities.

         The Company has completed a review concerning the ability of its
internal information systems, including its internal accounting systems, to
handle date information and function appropriately from and after January 1,
2000. The steps necessary to become Year 2000 Compliant are expected to be
completed by January 31, 2000 at an estimated cost of less than $100,000.


New Accounting Pronouncements

         In June 1998, the Financial Accounting Standards Board issued FSAS No.
133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133"). SFAS No. 133 requires companies to recognize all derivative contracts as
either assets or liabilities in the balance sheet and to measure them at their
fir values. If certain conditions are met, a derivative may be specifically
designed as a hedge, the objective of which is to match the timing of gain or
loss recognition on the hedging derivative with the recognition of (i) the
changes in the fair value of the hedged assets or liability or (ii) the earnings
effect of the hedged forecasted transaction. For a derivative not designated as
a hedging instrument, the gain or loss is recognized income in the period of
change. SFAS No. 133, as amended by SFAS No. 137, is effective for all fiscal
quarters of fiscal years beginning after June 15, 2000.

                                                                              16
<PAGE>

         Historically, the Company has not entered into derivative contracts
either to hedge existing risks or for speculative purposes. Accordingly, the
Company does not expect adoption of the new standard to effect its financial
statements.

Report of Independent Certified Public Accountants


To the Board of Directors and Stockholders
Avitar, Inc.

We have audited the accompanying consolidated balance sheet of Avitar, Inc. and
subsidiaries as of September 30, 1999, and the related consolidated statements
of operations, stockholders' equity (deficit) and cash flows for each of the two
years in the period ended September 30, 1999. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Avitar, Inc. and
subsidiaries as of September 30, 1999, and the results of their operations and
their cash flows for each of the two years in the period ended September 30,
1999, in conformity with generally accepted accounting principles.

       Revenue                        Sales of products and services are
       Recognition                    recorded in the period the products are
                                      shipped or services are provided.

       Cash                           Equivalents The Company considers all
                                      highly liquid investments and
                                      interest-bearing certificates of deposit
                                      with original maturities of three months
                                      or less to be cash equivalents.

       Inventories                    Inventories are recorded at the lower of
                                      cost (determined on a first-in, first-out
                                      basis) or market.

       Property and                   Property and equipment (including
       Equipment                      equipment under capital leases) is
                                      recorded at cost at the date of
                                      acquisition. Depreciation is computed
                                      using the straight-line method over the
                                      estimated useful lives of the assets
                                      (three to seven years). Leasehold
                                      improvements are amortized over the terms
                                      of the leases. Expenditures for repairs
                                      and maintenance are expensed as incurred.

       Goodwill                       Goodwill resulting from the excess of cost
                                      over fair value of net assets acquired is
                                      being amortized on a straight-line basis
                                      over 10 years. The Company evaluates the
                                      recoverability and remaining life of its
                                      goodwill and determines whether the
                                      goodwill should be completely or partially
                                      written-off or the amortization period
                                      accelerated. The Company will recognize an
                                      impairment of goodwill if undiscounted
                                      estimated future operating cash flows of
                                      the acquired business are determined to be
                                      less than the carrying amount of the
                                      goodwill. If the Company determines that
                                      the goodwill has been impaired, the
                                      measurement of the impairment will be
                                      equal to the excess of the carrying amount
                                      of the goodwill over the amount of the
                                      undiscounted estimated future operating
                                      cash flows. If an impairment of goodwill
                                      were to occur, the Company would reflect
                                      the impairment through a reduction in the
                                      carrying value of goodwill.

       Patents                        Patent costs are being amortized over
                                      their estimated useful lives of 5 - 7
                                      years by the straight-line method.

       Research and                   Research and development costs are
       Development                    expensed as incurred.

       Income (Loss)                  The Company follows Statement of Financial
       Per Share of                   Accounting Standards No. 128 ("SFAS 128")
       Common Stock                   "Earnings per Share." Under SFAS 128,
                                      basic earnings per share excludes the
                                      effect of any dilutive options, warrants
                                      or convertible securities and is computed
                                      by dividing the net income (loss)
                                      available to common shareholders by the
                                      weighted average number of common shares
                                      outstanding for the period. Diluted
                                      earnings per share is computed by dividing
                                      the net income (loss) available to common
                                      shareholders by the sum of the weighted
                                      average number of common shares and common
                                      share equivalents computed using the
                                      average market price for the period under
                                      the treasury stock method.

       Income                         Taxes Income taxes are accounted for using
                                      the liability method as set forth in

2.     Summary of
       Significant
       Accounting
       Policies
       (Continued)

       Recent                         In June 1998, the Financial Accounting
       Accounting                     Standards Board issued SFAS No. 133,
       Standards                      "Accounting for Derivative Instruments and
                                      Hedging Activities." SFAS No. 133 requires
                                      companies to recognize all derivative
                                      contracts at their fair values, as either
                                      assets or liabilities on the balance
                                      sheet. If certain conditions are met, a
                                      derivative may be specifically designated
                                      as a hedge, the objective of which is to
                                      match the timing of gain or loss
                                      recognition on the hedging derivative with
                                      the recognition of (1) the changes in the
                                      fair value of the hedged asset or
                                      liability that are attributable to the
                                      hedged risk, or (2) the earnings effect of
                                      the hedged forecasted transaction. For a
                                      derivative not designated as a hedging
                                      instrument, the gain or loss is recognized
                                      in income in the period of change. SFAS
                                      No. 133, as amended by SFAS No. 137, is
                                      effective for all fiscal quarters of
                                      fiscal years beginning after June 15,
                                      2000.

                                      Historically, the Company has not entered
                                      into derivative contracts either to hedge
                                      existing risks or for speculative
                                      purposes. Accordingly, the Company does
                                      not expect adoption of the new standard to
                                      affect its financial statements.

                                                                            F-13

3.     Acquisition                    On July 9, 1999 the Company acquired all
                                      the outstanding capital stock of United
                                      States Drug Testing Laboratories, Inc.
                                      ("USDTL") in exchange for approximately 2
                                      million restricted shares of common stock
                                      of Avitar which were valued at fair value
                                      at the date of acquisition. The amount of
                                      consideration was determined by arm's
                                      length negotiation between Avitar and the
                                      majority stockholders of USDTL, taking
                                      into account the revenues and prospects
                                      for USDTL. The acquisition was recorded
                                      using the purchase method of accounting.
                                      USDTL is engaged in the business of
                                      providing specialized laboratory testing
                                      operations including substance abuse
                                      identification and other related services.

12.    Stockholders'
       Equity
       (Continued)

       Stock Options                  The Company has stock option plans
                                      providing for the granting of incentive
                                      stock options for up to 750,000 shares of
                                      common stock to certain employees to
                                      purchase common stock at not less than
                                      100% of the fair market value on the date
                                      of grant. Each option granted under the
                                      plan may be exercised only during the
                                      continuance of the optionee's employment
                                      with the Company or during certain
                                      additional periods following the death or
                                      termination of the optionee. For options
                                      granted before fiscal 1999, each employee
                                      is fully vested in all options granted
                                      under the Plan after the completion of two
                                      years of continuous service to the
                                      Company. If the optionee has been employed
                                      by the Company for a period of less than
                                      two years, all options granted under the
                                      plan vest at a rate of 50% per year.
                                      Options granted in fiscal 1999 vest at a
                                      rate of 20% per year.

                                      During fiscal 1995, the Company adopted a
                                      directors' plan, (the "Directors' Plan").
                                      Under the Directors' Plan, each
                                      nonmanagement director is to be granted
                                      options covering 5,000 shares of common
                                      stock initially upon election to the
                                      Board, and each year in which he/she is
                                      selected to serve as a director. In fiscal
                                      1999 and 1998, no options were granted to
                                      directors under the Directors' Plan,
                                      although 210,000 options were granted to
                                      directors outside of the Director's Plan.

                                      During 1998, 1,227,350 options held
                                      primarily by employees and directors of
                                      the Company at exercise prices ranging

                                      reissued at prices ranging from $.20 -

                                      current stock price at the reissue date.
                                      These options are included in cancelled

                                      yield of 0% for both years and expected
                                      volatility of 45.8% for 1999 and 46.60%
                                      for 1998, risk free rates ranging from
                                      4.60% to 6.13% for 1999 and 5.26% to 5.59%
                                      for 1998, and expected lives of 5-9 years
                                      for 1999 and 1-9 years for 1998.

                                      The weighted average fair value of options
                                      granted in fiscal 1999 and 1998 was $.41

12.    Stockholders'
       Equity
       (Continued)

       Settlement of                  A.S. Goldmen & Company, Inc.
       Litigation                     ("Underwriter") and certain holders of the
                                      Underwriter's warrants issued by the
                                      Company had previously commenced a court
                                      action against the Company in the Federal
                                      Court for the Southern District of New
                                      York (the "Court"). In December 1998, the
                                      Court denied the Company's motion to
                                      dismiss this action, but the Court did not
                                      decide and expressly left open the
                                      principal legal argument urged by the
                                      Company in favor of dismissal. In March
                                      1999, this action was settled and
                                      discontinued with prejudice. In connection
                                      with the settlement, the Company issued
                                      400,000 shares of common stock.

13.    Income Taxes                   No provision for Federal income taxes has
                                      been made for the years ended September
                                      30, 1999 and 1998, due to the Company's
                                      operating losses. At September 30, 1999,
                                      the Company has unused net operating loss
                                      carryforwards of approximately $24,600,000
                                      (including approximately $11,000,000
                                      acquired from ATI) which expire at various
                                      dates through 2019. Most of this amount is
                                      subject to annual limitations due to
                                      various "changes in ownership" that have
                                      occurred over the past few years.
                                      Accordingly, most of the net operating
                                      loss carryforwards will not be available
                                      to use in the future.

                                      As of September 30, 1999 and 1998, the
                                      deferred tax assets related to the net
                                      operating loss carryforwards have been
                                      fully offset by valuation allowances,
                                      since the utilization of such amounts is
                                      uncertain.

                                                                            F-29

</TABLE>

                                      At September 30, 1999, accounts receivable
                                      from these major customers totaled
                                      approximately $113,793.

                                      One product represents the majority of
                                      ATI's sales. The Company purchases the
                                      materials for this product from one
                                      supplier. The loss of this supplier could
                                      have a material adverse effect on the
                                      Company.

15. Subsequent                        Subsequent to year end, the Company
    Events                            received $242,000 in connection with the
                                      preferred stock subscription receivable,
                                      as well as $2,598,000 in connection with
                                      the sale of Series C convertible preferred
                                      stock and the exercise of warrants.

the Company's officers and directors, and persons who own more than ten percent
of a

                                                                              20

registered class of the Company's equity securities to file reports of ownership
and changes in ownership with the Securities and Exchange Commission and NASDAQ.
Officers, directors and greater than ten-percent shareholders are required by
SEC regulation to furnish the Company with copies of all Section 16(a) forms
they file.

         Based on its review of the copies of such forms received by it, or
written representations from certain reporting persons that no Forms 5 were
required for those persons, the Company believes that, during Fiscal 1999, all
filing requirements applicable to its officers, directors and greater than
ten-percent shareholders were complied with except the following failures to
file timely reports required by Section 16(a):


         * One report (Form 4) covering 2 transactions was filed late by Peter
                 Phildius.
         * One report (Form 4) covering 3 transactions was filed late by Douglas
                 Scott.

         PK&S is a partnership, two of whose general partners are Messrs.
Phildius and Scott. PK&S provided management consulting services to the Company
through May 18, 1995 pursuant to a written consulting agreement effective May
28, 1992. Under this agreement, Messrs. Phildius and Scott each devoted
approximately 20 hours per week to the Company's affairs for which the Company
paid a monthly consulting fee of $14,500 and reimbursed expenses. Since May 19,
1995, the Company has paid PK&S the salary and employee benefit amounts provided
under the terms of the Company's employment agreements with Messrs. Phildius and
Scott. See "Employment Agreements" below and Item 12. "Certain Relationships and
Related Transactions" below.

         Stock Option Grants in Last Fiscal Year. On January 18, 1999, the
Outside Directors of the Company's Board of Directors granted options to
purchase the Company's common stock in the amount of 1,450,000 to Mr. Phildius
and 850,000 to Mr. Scott. Such options have an exercise price of $.345 per share
and will expire on January 18, 2009. Of the 2,300,000 options granted to Mr.
Phildius and Mr. Scott, 380,000 are vested and exercisable, 960,000 options vest
and become exercisable at the rate of 20% per year for five years and the
remaining 960,000 options vest and become exercisable on the earlier of meeting

         Option Exercises in Last Fiscal Year and Year-Ended Option Values. No
stock options or stock appreciation rights were exercised by Mr. Scott and Mr.
Phildius in Fiscal 1999.

         As of September 30, 1999, Mr. Phildius held options covering 1,800,000
shares of Common Stock, 490,000 of which are exercisable, all of which are in
the money. Mr. Scott held options covering 1,200,000 shares of Common Stock,
490,000 of which are exercisable, all of which are in the money.

         Employment Agreements. Under Employment Agreements (the "Employment
Agreements") which commenced on May 19, 1995, Messrs. Phildius and Scott each
receive an annual salary of $150,000 (subject to cost of living increases).
Pursuant to the Employment Agreements, if Messrs. Phildius and/or Scott are
terminated with "Cause" (as such term is defined in the Employment Agreements)
by the Company or if Messrs. Phildius and/or Scott terminate their employment as
a result of a breach by the Company of its obligations under such Agreements, he
will be entitled to receive his annual base salary for a period of up to 18
months following such termination. In addition, if there is a "Change of
Control" of the Company (as such term is defined in the Employment Agreements)
and, within two years following such "Change of Control", either of Messrs.

                                                                              22

Phildius or Scott is terminated without cause by the Company or terminates his
employment as a result of a breach by the Company, such executive will be
entitled to certain payments and benefits, including the payment, in a lump sum,
of an amount equal to up to two times the sum of (i) the executive's annual base
salary and (ii) the executive's most recent annual bonus (if any). In addition,
pursuant to the Employment Agreements, which have a three-year term (subject to
extension), Messrs. Phildius and Scott are each entitled to annual bonus
payments of up to $150,000 if the Company achieves certain levels of Pre-tax
Income (as such term is defined in such Agreements). The stock options granted
under the Employment Agreements (covering an aggregate of 203,000 shares) were
canceled by the Company, and new options to purchase an aggregate of 380,000
shares of the Company's Common Stock at an exercise price of $0.59 per share
were granted unconditionally and independently of the Employment Agreements.
Such options expired on June 16, 1999 and were replaced by the Company in with
options, which are vested and exercisable, to purchase an aggregate of 380,000
shares of the Company's common stock at $.345 per share until January 18, 2009.
In July 1995, the Company's Board of Directors granted additional options in the
amount of 250,000 to Mr. Phildius and 250,000 to Mr. Scott at exercise prices of
$.375 per share until July 12, 2005. These options, which are vested and
exercisable, were canceled and replaced during Fiscal 1998 with options having
the same expiration dates and exercise prices of $.25 per share.

         Director Compensation. The Company presently pays its non-management
directors $500 for each Board and Committee meeting, which they attend plus a
travel fee of $250 if they must travel outside of the area to attend the
meeting. In consideration of the fact that the Company does not pay its
non-management directors an annual retainer, the Company adopted a directors'
plan (the "Directors' Plan"), which was approved by the Stockholders on May 18,
1995. Under the Directors' Plan, each non-management director is to be granted
options covering 5,000 shares of the Company's Common Stock initially upon
election of the Board, and each year in which he/she is selected to serve as a
director. On June 16, 1994, the Board of Directors granted to each member of the
Special Independent Committee options to purchase 10,000 shares of the Company's
Common Stock at an exercise price of $0.59 per share, representing the fair
market value of the Company's Common Stock on the date of such grant. Such
options represent an initial special grant as well as the grant for calendar
year 1995. Such options became effective on May 19, 1995, the consummation of
the Merger. In March 1997, each non-management director received a grant of
5,000 options for calendar year 1997 with an exercise price of $0.83 per share,
representing the fair market value of the Company Common Stock on the date of
such grant. During Fiscal 1998, all options described above were canceled and
replaced with options that have an exercise price of $.25 per share with no
change in the expiration dates. Also during Fiscal 1998, the Company's Outside
Directors were each granted options to purchase 70,000 shares of the Company's
Common Stock at an exercise price of $.25 per share until February 4, 2008.
These new options vest and become exercisable on the basis of 50% on February 4,
1999 and 50% on February 4, 2000.

                                                                              23

ITEM 12. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         PK&S, a 5.3 % beneficial owner of the Company, provided consulting
services to the Company from September 1989 to May 1995. On May 28, 1992, the
Company entered into a written consulting agreement with PK&S, which reflected
the provisions of a previous oral agreement approved by the Company's Board of
Directors in October 1990. Pursuant to its arrangement with the Company, PK&S
provided the services of each of Messrs. Phildius and Scott to the Company for
approximately 20 hours per week. Under the terms of the current employment
agreements with Peter Phildius and Douglas Scott described above, the Company
pays their salaries and related expenses directly to PK&S. The aggregate of
consulting fees, salaries, fringe benefits and reimbursement of expenses paid to
PK&S by the Company for fiscal years 1999, 1998 and 1997 totaled $387,310,
$335,137 and $318,160 respectively.

         In connection with its consulting arrangement with the Company, PK&S
was granted options to purchase an aggregate of 1.6 million shares of the
Company Common Stock prior to the one for 54.9 stock split effected by the
Company in November 1991 (the "Stock Split"). In December 1991, following the
Stock Split, the Company's Board of Directors canceled these previously granted
options and replaced them with five-year options covering an aggregate of
120,000 shares of the Company Common Stock, of which options covering 60,000
shares are exercisable at $0.80 per share and options covering an additional
60,000 shares were exercisable at $2.00 per share. Such options were granted to
PK&S as compensation for services rendered to the Company. The number of shares
of Company Common Stock covered by such options was approximately 91,000 shares
more than those which PK&S would have received pursuant to the Stock Split
alone, and the exercise prices and other terms of such options were more
favorable than those of the options that they replaced. On June 16, 1994, the
Company's Board of Directors canceled the options covering 60,000 shares with an
exercise price of $2.00 per share and replaced them with options covering a like
number of shares, at $0.59 per share, the fair market value of the Company
Common Stock as of June 16, 1994. The options covering 60,000 shares of common
stock at the exercise price of $0.80 per share expired in December 1996. The
remaining 60,000 shares of Company Common Stock covered by such options are
subject to certain demand registration rights granted to PK&S. Pursuant to these
registration rights, PK&S has the right, which commenced on September 18, 1993,
to cause the Company to register the shares of the Company Common Stock
underlying these options.

         On September 3, 1994, PK&S made a bridge loan to the Company in the
amount of $300,000, with interest payable thereon monthly in arrears at 10% per
annum. The loan is to be repaid in the amount of one-third of the net proceeds
to the Company (up to $300,000 plus accrued interest thereon) resulting from a
private placement of the

                                                                              26
<PAGE>

Company securities upon the earlier of September 2, 1995, or seven days
following completion of such private placement. In connection with the loan, the
Company granted to PK&S warrants to purchase 300,000 shares of the Company's
Common Stock at an exercise price of $0.65 per share, the average bid price of
the Company Common Stock during the 10 days prior to August 17, 1994, the date
the loan from PK&S was approved by the Special Independent Committee. These
warrants were exercised by PK&S in November 1996.

         On December 16, 1994, the Company granted to PK&S warrants to purchase
112,500 shares of the Company's Common Stock at an exercise price of $0.50 per
share in connection with an additional bridge loan of $75,000 made by PK&S to
the Company. In addition, during January 1995, Messrs. Phildius and Scott and
Michael Kenyon, a general partner of PK&S, made bridge loans in an aggregate
amount of $110,000 to the Company. In connection with these loans, the Company
granted to them warrants to purchase an aggregate of 165,000 shares of the
Company Common Stock at an exercise price of $0.50 per share. These warrants
were exercised by PK&S in November 1996.

         In connection with the bridge loans totaling $375,000 made by PK&S to
the Company, PK&S, on September 30, 1995, exchanged its bridge note, and accrued
interest thereon, for 388,856 shares of Series A Convertible Preferred Stock.
Each share of Series A Convertible Preferred Stock entitles PK&S to convert it
at any time into three shares of the Company's Common Stock and receive
dividends in an amount equal to 110% of any dividends paid on the Company's
Common Stock into which each share is convertible. These shares of Series A
Convertible Preferred Stock were converted into 1,166,568 shares of Company
Common Stock in February 1997.

         On May 19, 1995, the Company's Consulting Agreement ended and was
replaced by the Employment Agreements with Messrs. Phildius and Scott (See
"Employment Agreements"). As requested by Messrs. Phildius and Scott and
approved by the Company's Board of Directors, the salary and benefits provided
under the Employment Agreements will be paid directly to PK&S.

         In July 1995, the Company entered into a consulting agreement with
Richard Freemen, M.D., the son-in-law of the Company's Chairman and Chief
Executive Officer. Under this agreement, Dr. Freemen was to act as Chairman of
ATI's Medical Advisory Board and was compensated $5,000 per month for the
duration of the agreement. In addition, Dr. Freemen received options to purchase
20,000 shares of the Company's Common Stock. The consulting portion of this
agreement was canceled in February 1997 and an issuance of 100,000 shares of the
Company's Common Stock was made to Mr. Freeman to cover the total compensation
earned under this agreement.

         From April-October 1997, officers and affiliates of the Company made
loans to the Company totaling $428,723 with interest payable at 10% per annum.
Of these loans, $368,723 was due on or before September 30, 1997 with the
balance of $60,000 due on
                                                                              27
<PAGE>

or before January 31, 1998. In November 1997, loans in the total amount of
$60,000 (plus the accrued interest thereon) due on or before January 31, 1998
were repaid. In March 1998, these loans totaling $368,723 plus accrued interest
thereon of approximately $31,000 were repaid by the Company with 1,818,020
shares of the Company's common stock and warrants to purchase 400,000 shares of
the Company's common stock for $.28 per share until March 2003.

         In October 1996, the Company entered into a consulting agreement with
N.R. Gordon & Company, Inc. Neil Gordon, a member of the Company's Board of
Directors, is the President of N.R. Gordon and Company, Inc. Under this
agreement, N.R. Gordon & Company, Inc. provided financial consulting services
for which it received 50,000 warrants at an exercise price of $0.93 per share
and is paid $100.00 per hour for all services performed. In addition, N.R.
Gordon & Company, Inc. is entitled to receive commissions for certain capital
raising services. During Fiscal 1998, Company canceled the 50,000 warrants
granted to N.R. Gordon & Company in 1996 and replaced them with 100,000 warrants
to purchase the Company's Common Stock for $.25 per share until October 2001.

                   (Pursuant to Section 151(g) of the General
                    Corporation Law of the State of Delaware)

         We, the undersigned duly authorized officers of AVITAR, INC., a
corporation organized and existing under the laws of the State of Delaware, do
hereby certify that:

         A. AVITAR, INC. (the "Corporation") was incorporated in the State of
Delaware on November 20, 1986.

         B. Pursuant to the authority conferred upon the Board of Directors of
the Corporation (the "Board of Directors") by the provisions of the
Corporation's Certificate of Incorporation, as amended (the "Certificate of
Incorporation"), and the provisions of Sections 141 and 151 of the General
Corporation Law of the State of Delaware, the Board of Directors has duly
adopted the following recitals and resolutions, which are not in conflict with
any provisions of the Certificate of Incorporation or the Corporation's By-Laws,
setting forth the number, terms, designations, relative rights, preferences,
privileges and restrictions of a series of Preferred Stock, par value $0.01 per
share, of the Corporation.

         WHEREAS, the Certificate of Incorporation provides for a class of
shares known as Preferred Stock, consisting of 5,000,000 shares;

         WHEREAS, the Certificate of Incorporation authorizes the issuance of
Preferred Stock from time to time in one or more series and authorizes the Board
of Directors to (a) determine or alter the rights, preferences, privileges and
restrictions granted to or imposed upon any wholly unissued series of Preferred
Stock, (b) fix the number of shares constituting any such series and
(c) determine the designation thereof; and



                                       2
<PAGE>



         WHEREAS, the Corporation plans to issue a second series of Preferred
Stock and the Board of Directors desires to determine and fix the rights,
privileges, and restrictions relating to this series of Preferred Stock and the
number of shares constituting, and the designation of, such series.

         NOW, THEREFORE, BE IT RESOLVED, that the Board of Directors hereby
determines and fixes the designations of, the number of shares constituting, and
the rights, preferences, privileges and restrictions relating to, a second
series of Preferred Stock, as follows:

         1. Designation. 600,000 shares of Preferred stock shall be designated
hereby as "Series B Redeemable Convertible Preferred Stock" (hereinafter
referred to as the "Series B Preferred Stock") with the rights, preferences,
privileges and restrictions specified herein.

         2. Voting Rights. On all matters submitted to a vote of the holders of
the Corporation's common stock, par value $0.01 per share (the "Common Stock),
the holders of Series B Preferred Stock shall be entitled to exercise one vote
per share of Series B Preferred Stock.

         3. Dividends. The holders of Series B Preferred Stock shall be entitled
to receive, at the discretion of the Company, an annual 8% cash dividend or 10%
stock dividend computed on the amount invested in the Series B Preferred Stock.
Stock dividends shall be paid in shares of Series B Preferred Stock based on the
average closing price of ten (10) shares of the Common Stock for the five
trading days prior to the five days before the dividend is paid. Such dividend
shall be payable within ninety (90) days after the anniversary date of the
investment upon which the dividend is based.

         4. Liquidation Preference.

            A. Upon any voluntary or involuntary liquidation, dissolution or
winding-up of the Company, the holders of Series B Preferred Stock shall be
entitled to receive out of the assets of the Corporation which remain after
satisfaction in full of all valid claims of creditors of the Corporation,
liquidating distributions of an amount per share of Series B Preferred Stock
equal to the amount per share for Series B Preferred Stock paid by the holder
when making the investment. If these liquidation distributions are not paid in
full, the holders of the Series B Preferred Stock shall share ratably in any
distribution of assets in proportion to the full respective preferential amount
to which they are entitled.

            B. The merger or consolidation of the Corporation with or into any
other corporation and the sale or transfer of all or substantially all of the


                                       3
<PAGE>



assets of the Corporation shall be deemed to be a dissolution, liquidation or
winding-up of the Corporation for the purposes of this Section 4.

            C. Written notices of any voluntary liquidation, dissolution or
winding-up of the Corporation, stating the payment date or dates when, and the
place or places where, the amounts distributable to holders of Series B
Preferred Stock in such circumstances shall be payable, shall be given by
first-class mail, postage pre-paid, mailed not less than twenty (20) days prior
to any payment stated therein, to the holders of Series B Preferred Stock, at
the address shown on the books of the Corporation or any transfer agent for the
Series B Preferred Stock.

            D. The Corporation may issue shares of its Preferred Stock which
have liquidation, dividend, voting, and/or redemption rights which are senior or
junior to, or pari passu with, the Series B Preferred Stock.


         5. Conversion.

            A. A holder of Series B Preferred Stock shall be entitled, at any
time prior to the close of business on any date fixed for the redemption of such
shares pursuant to Section 6 hereof, to cause any or all such shares to be
converted (the "Conversion") into ten shares of Common Stock for each share of
Series B Preferred Stock (the "Conversion Price"), subject to adjustment as
provided herein.

            B. The issuance by the Corporation of shares of Common Stock upon
any Conversion of shares of the Series B Preferred Stock made at the option of
the holder thereof, shall be effective the earlier of (i) the delivery to such
holder or such holders' designee of certificates representing the shares of
Common Stock issued upon Conversion thereof or (ii) the commencement of business
on the second business day after the surrender of the certificate or
certificates for the shares of Series B Preferred Stock to be converted, duly
assigned or endorsed for transfer to the Corporation ( or accompanied by duly
executed stock powers relating thereto) as provided hereby. On and after the
effective date of any Conversion, the converted shares of Series B Preferred
Stock shall no longer be deemed to be outstanding and all rights whatsoever with
respect thereto shall terminate, and the person or persons entitled to receive
the Common Stock issuable upon such Conversion shall be treated for all purposes
as the record holder or holders of such shares of Common Stock. All shares of
Series B Preferred Stock upon Conversion shall be restored to the status of
authorized but unissued shares of preferred stock without designation as to
Class, and may be issued thereafter.



                                       4
<PAGE>



            C. The Conversion Price shall be subject to adjustment from time to
time as follows:

                  (i) If the Corporation shall, at any time or from time to time
         while shares of the Series B Preferred Stock shall be outstanding, (1)
         subdivide its outstanding shares of Common Stock into a greater number
         of shares, (2) combine its outstanding shares of Common Stock into a
         smaller number of shares or (3) pay a dividend (exclusive of the stock
         dividend provided herein), or make a distribution in Common Stock (or
         securities convertible into or exchangeable for shares of Common Stock)
         to holders of the Common Stock or other class or series of capital
         stock of the Corporation convertible into or exchangeable for shares of
         Common Stock, then the Conversion Price in effect immediately prior to
         such subdivision or combination, as the case may be, or immediately
         prior to the record date fixed for the determination of shareholders
         entitled to such dividend or distribution, shall be increased or
         decreased, as the case may be, to produce such results as would have
         been obtained prior to the occurrence of such event. An adjustment made
         pursuant hereto shall become effective immediately after the record
         date, in the case of a dividend or distribution payable in Common Stock
         (or other securities) and immediately after the effective date, in the
         case of a subdivision or combination.

                  (ii) If the Corporation shall, at any time or from time to
         time while shares of Series B Preferred Stock shall be outstanding,
         sell or issue rights, options, warrants or convertible securities
         containing the right to subscribe for or purchase shares of Common
         Stock at a purchase price less than the Conversion Price (i.e. 10% of
         the amount invested per share for Series B Preferred Stock), then the
         Conversion Price in effect immediately prior to such event shall be
         reduced by an amount equal to the quotient determined by dividing:

                  (a) an amount equal to the sum of (x) the product of the total
         number of shares of Common Stock outstanding immediately prior to the
         date of such sale or issuance of such rights, options, warrants or
         convertible securities and the Conversion Price in effect immediately
         prior to such sale or issuance, plus (y) the aggregate consideration
         (if non-cash consideration, the fair market value of which shall be
         determined by the Board of Directors in its good faith judgment), if
         any, received by the Corporation upon such sale or issuance; by

                  (b) the total number of shares of Common Stock outstanding
         immediately after such sale or issuance.



                                       5
<PAGE>



               (iii) Whenever any adjustment is made in the Conversion Price
          pursuant to the foregoing provisions (i) or (ii), the Corporation
          shall, as soon as reasonably practicable thereafter, prepare a written
          statement signed by an executive officer of the Corporation setting
          forth the adjusted Conversion Price, determined as provided herein,
          and, in reasonable detail, the facts requiring such adjustment. The
          Corporation shall mail such statement to all holders of record of
          shares of Series B Preferred Stock at their respective addresses
          appearing on the stock records of the Corporation.

            D. The Corporation shall at all times reserve and keep available out
of its authorized and unissued Common Stock, solely for issuance upon the
Conversion of shares of Series B Preferred Stock as provided herein, free from
any preemptive rights, such number of shares of Common Stock as shall from time
to time be issuable upon the Conversion of all the shares of Series of Series B
Preferred Stock then outstanding.

         6. Redemption.

            A. In the event that the average of the last sales price ten shares
of Common Stock equal or exceeds 300% of the amount invested per share for
Series B Preferred Stock for any (20) consecutive trading days immediately prior
to the date of the notice discussed in Section 6.B below, the Corporation shall
have the right, at any time, to redeem all, or any portion of, the outstanding
shares of Series B Preferred Stock, at the price per share paid by the holder
upon making the investment in Series B Preferred Stock. If less than all of the
outstanding shares of Series B Preferred Stock shall be redeemed, the
Corporation shall redeem a pro rata portion of the shares of each holder. From
and after the date of redemption of any shares of Series B Preferred Stock, such
shares shall no longer be deemed to be outstanding and all rights in respect of
such shares of Series B Preferred Stock shall cease, except the right to receive
the redemption price.

            B. Notice of any redemption made pursuant to this Section 6 shall be
sent to the holders of Series B Preferred Stock at the address shown on the
books of the Corporation or any transfer agent for the Series B Preferred Stock
by first class mail, postage prepaid, mailed not less than thirty (30) days'
prior to the redemption date. Each notice shall state (i) the redemption date,
(ii) the total number of shares of Series B Preferred Stock to be redeemed and,
if fewer than all the shares held by such holder are to be redeemed, the number
of shares to be redeemed from such holder, (iii) the redemption price, (iv) the
place or places where certificates for such shares are to be surrendered for

               c.   Liquidation Preference. Upon any voluntary liquidation,

                    assets of the Company which remain after satisfaction in
                    full of all valid claims of creditors of the Company,
                    liquidating distributions of an amount per share equal to
                    the Offering Price. Should these liquidation distributions
                    not be paid in full, the holders of the Preferred Stock
                    shall share ratably in any distribution of assets in
                    proportion to the full respective preferential amount to

               d.   Conversion. A holder of the Preferred Stock shall be
                    entitled, at any time prior to the close of business on any
                    date fixed for the redemption of such shares, to cause any
                    or all such shares to be converted into ten shares of the
                    Company's Common Stock for each share of Preferred Stock (
                    the "Conversion Price"), subject to the anti-dilution
                    provisions provided herein. The issuance by the Company of
                    shares of Common Stock upon any conversion of shares of the
                    Preferred Stock made at the option of the holder thereof,
                    shall be effective as of the earlier of (i) the delivery to
                    such holder or such holders' designee of certificates
                    representing the shares of Common Stock issued upon
                    Conversion thereof or (ii) the commencement of business on
                    the second business day after the surrender of the
                    certificate or certificates for the shares of Preferred
                    Stock to be converted, duly assigned or endorsed for
                    transfer to the Company (or accompanied by duly executed
                    stock powers relating thereto) as provided hereby. On or
                    after the effective date of any Conversion, the converted
                    shares of the Preferred Stock shall no longer be deemed to
                    be outstanding and all rights whatsoever with respect
                    thereto shall terminate, and the person or persons entitled
                    to receive the Common Stock issuable upon such Conversion
                    shall be treated for all purposes as the record holder or
                    holders of such shares of Common Stock. All shares of the
                    Preferred Stock upon Conversion shall be restored to the
                    status of authorized but unissued shares of preferred stock
                    without designation as to Class, and may be issued
                    thereafter. The Conversion Price shall be

                    any payment by the Company of a stock dividend to the
                    holders of the Company's Common Stock holders or holders of
                    any other of stock convertible into Common Stock, or (iii)
                    any future issue of stock or securities convertible into the
                    Common Stock of the Company at a price less than the

                    exceed 300% of the Offering Price for any twenty (20)
                    consecutive trading days prior to the notice of redemption,
                    the Company shall have the right, at any time, to redeem all

                    Stock, at the Offering Price. If less than all outstanding
                    shares of the Preferred Stock shall be redeemed, the Company
                    shall redeem a pro rata portion of the shares of each
                    holder. Notice of any redemption shall be sent to the
                    holders of the Preferred Stock at the address shown on the

                    and the Company and all such questions have been answered to
                    the full satisfaction of the Purchasers and the Advisors, if
                    any.

               f.   In evaluating the suitability of an investment in the
                    Company, the Purchaser has not relied upon any
                    representation or other information (oral or written) other
                    than as stated in this Subscription Agreement and/or as
                    contained in the Disclosure Documents.

               g.   The Purchaser is unaware of, is no way relying on, and did
                    not become aware of the Offering of the Shares through or as
                    a result of any form of general solicitation or general
                    advertising, including, without limitation, any article,
                    notice, advertisement or other communication published in
                    any newspaper, magazine or similar media or broadcast over
                    television or radio, in connection with the Offering and is
                    not subscribing for the Shares and did not become aware of
                    the Offering through or as a result of any seminar or
                    meeting to which the Purchaser was invited by, or any
                    solicitation of a subscription by, a person not previously
                    known to the Purchaser in connection with investments in
                    securities generally.

               h.   The Purchaser has taken no action which would give rise to
                    any claim by any person for brokerage commissions, finders'
                    fees or the like relating to this Subscription Agreement or
                    the transactions contemplated hereby.

               i.   The Purchaser, together with the Advisors, have such
                    knowledge and experience in financial, tax, and business
                    matters, and, in particular, investments in securities, so
                    as to enable them to utilize the information made available
                    to them in connection with the Offering to evaluate the
                    merits and risks of an investment in the Shares and to make
                    an informed investment decision with respect thereto.

               j.   The Purchaser is not relying on the Company or any of its
                    officers, directors, employees or agents with respect to the
                    legal, tax, economic and related considerations of an
                    investment in the Shares, and the Purchaser has relied on
                    the advice of, or has consulted with, only his own Advisors
                    (if any).

               k.   The Purchaser is acquiring the Shares solely for such
                    Purchaser's own account for investment and not with a view
                    to resale or distribution



                                       8
<PAGE>




                    thereof, in whole or in part. The Purchaser has no agreement
                    or arrangement, formal or informal, with any person to sell
                    or transfer all or any part of the Shares, and the Purchaser
                    has no plans to enter into any such agreement or
                    arrangement.

               l.   The Purchaser must bear the substantial economic risks of an
                    investment in the Shares indefinitely because the Shares may
                    not be sold, hypothecated or otherwise disposed of unless
                    subsequently registered under the Securities Act and
                    applicable state securities laws or an exemption from such
                    registration is available. The Purchaser acknowledges that
                    legends shall be placed on the shares of Common Stock,
                    issued pursuant to the conversion of the Preferred Stock, to
                    the effect that they have not been registered under the
                    Securities Act or applicable state securities laws and
                    appropriate notations thereof will be made in the Company's
                    stock books. Stop transfer instructions will be placed with
                    the transfer agent of the Company.

               m.   The Purchaser has adequate means of providing for such
                    Purchaser's current financial needs and foreseeable
                    contingencies and has no need for liquidity of the
                    investment in the Shares for an indefinite period of time.

               n.   The Purchaser is aware that an investment in the Shares
                    involves a number of very significant risks and investment
                    considerations.

               o.   The Purchaser meets the requirements of at least one of the
                    suitability standards for an "accredited investor" under
                    Regulation D promulgated under the Securities Act and as set
                    forth on the Accredited Investor Certification contained
                    herein.

               p.   The Purchaser: (i) if a natural person represents that the
                    Purchaser has reached the age of 21 and has full power and
                    authority to execute and deliver this Subscription Agreement

                    contingencies and emergencies and has no need for liquidity
                    in the investment in the Shares; (ii) if a corporation,
                    partnership, limited liability company or

                    such entity was not formed for the specific purpose of
                    acquiring the Shares, such entity is duly organized, validly
                    existing and in good standing under the laws of the state of

                    contemplated hereby is authorized by, and will not result in
                    a violation or breach of any law, regulation, agreement to
                    which it is a party or is otherwise bound or of its charter
                    or other organizational documents; such entity has full
                    power and authority to execute and deliver this Subscription
                    Agreement and all other related agreements or certificates

                    necessary action; this Subscription Agreement has been duly
                    executed and delivered on behalf of such entity and is a
                    legal, valid and binding obligation of such entity; and
                    (iii) if executing this Subscription Agreement in a
                    representative or fiduciary capacity, represents that it has
                    full power and authority to execute and deliver this
                    Subscription Agreement in such capacity and on behalf of the
                    subscribing individual, ward, partnership, trust, estate,
                    corporation, limited liability company or partnership, or
                    other entity for whom the Purchaser is executing this
                    Subscription Agreement, and such individual, ward,
                    partnership, trust, estate, corporation, limited liability
                    company or partnership, or other entity has full right and
                    power to perform pursuant to this Subscription Agreement and
                    make an investment in the Company; and that this
                    Subscription Agreement constitutes a legal, valid and
                    binding obligation of such entity. The execution and
                    delivery of this Subscription Agreement will not violate or
                    be in conflict with any order, judgment, injunction,
                    agreement or document to which the Purchaser is a party or
                    by which it is bound.

               q.   Any information which the Purchaser has heretofore furnished
                    or furnishes herewith to the Company is complete and
                    accurate and may be relied upon by the Company in
                    determining the availability of an exemption from
                    registration under Federal and state securities laws in
                    connection with the Offering. The Purchaser will notify and
                    supply corrective information to the Company immediately
                    (and without a specific



                                       10
<PAGE>



                    request therefor) upon the occurrence of any change therein
                    occurring prior to the Company's issuance of the Shares.

               r.   The Purchaser has significant prior investment experience,
                    including investment in non-registered securities. The
                    Purchaser has a sufficient net worth to sustain a loss of
                    its entire investment in the Company in the event such a
                    loss should occur. The Purchaser's overall commitment to
                    investments which are not readily marketable is not
                    excessive in view of his/its net worth and financial
                    circumstances and the purchase of the Shares will not cause
                    such commitment to become excessive. The investment is a
                    suitable one for the Purchaser.

               s.   No oral or written representations have been made, or oral
                    or written information furnished, to the Purchaser in
                    connection with the Offering which are in any way
                    inconsistent with the information contained herein.

               t.   The Purchaser acknowledges that, even if the Maximum Amount
                    is raised from the sale of the Shares, the net proceeds
                    thereof will provide the Company with the funds to meet only
                    its most immediate needs and that additional funds will be
                    required by the Company (with the consequent dilution of
                    value and/or ownership) through additional equity and/or
                    debt financing(s), and no assurance can be given as to the
                    availability or adequacy of terms of any such financing(s).
                    In the event that the Company does not obtain the requisite
                    funds, it may be necessary for the Company to reduce,
                    suspend or cease certain of its operations. The Purchaser
                    acknowledges that the Company intends to use the net
                    proceeds of the offering for its working capital
                    requirements.

               HEREBY.

          13.  Blue Sky Qualification. The purchase of the Shares under this
               Subscription Agreement is expressly conditioned upon the
               exemption from registration and/or qualification of the offer and
               sale of the Shares from applicable Federal and state securities
               laws. The Company shall not be required to qualify this
               transaction under the securities laws of any jurisdiction and,
               should qualification be necessary, the Company shall be released
               from any and all obligations to maintain the Offering, and may
               rescind any sale contracted, in the jurisdiction.

          14.  Piggyback Registration. If, at any time commencing after the date
               hereof until such time as the Purchaser has sold or otherwise
               disposed of the Shares, the holders of shares of the Preferred
               Stock shall be entitled to "piggyback" registration rights with
               respect to such shares on each occasion that the Company shall
               propose to file a registration statement on Form S-3 ( the
               "Registration Statement") under the Securities Act of 1933, as
               amended, covering any shares of Common Stock. The Company shall,
               at least thirty (30) days before filing any such Registration
               Statement, notify the holders of the Preferred Stock in writing
               of such filing. For a period of ten (10) days from the receipt of
               such notice, each holder of the Preferred Stock shall be entitled

                    OFFERING OR THE ACCURACY OR ADEQUACY OF THE

                    CONTRARY IS UNLAWFUL.

Stock") at any time or from time to time from the date hereof, through and
including _____________, 2000, (the "Termination Date") but not later than 5:00
p.m. New York City, New York Time on the Termination Date (the "Exercise
Period") at an initial exercise price equal to $______ per share. The number of
shares of Common Stock to be received upon the exercise of this Warrant and the
price to be paid for each share of Common Stock may be adjusted from time to
time as hereinafter set forth. The shares of Common Stock deliverable upon such
exercise, and as adjusted from time to time, are hereinafter sometimes referred
to as "Warrant Shares" and the exercise price of a share of Common Stock in
effect at any time and as adjusted from time to time is hereinafter sometimes
referred to as the "Exercise Price".

               (a) Exercise of Warrant. This Warrant may be exercised in whole
or in part at any time during the Exercise Period. This Warrant, subject to the
provisions hereof, may be exercised by presentation and surrender hereof to the
Company at its principal office, or at the office of its stock transfer agent,
if any, with the Purchase Form annexed hereto duly executed and accompanied by
payment of the Exercise Price for the number of Warrant Shares specified in such
exercise. The Company shall issue and deliver to the Holder a certificate or
certificates for the Warrant Shares issuable upon such exercise, registered in
the name of the Holder or its designee. If this Warrant should be exercised in
part only, the Company shall, upon surrender of this Warrant for cancellation,
execute and deliver a new Warrant evidencing the rights of the Holder thereof to
purchase the balance of the Warrant Shares purchasable thereunder. Upon receipt
by the Company of this Warrant at its office, or by the stock transfer agent of
the Company at its office, in proper form for exercise shall be deemed to be the
holder of record of the shares of Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or that certificates representing such shares of Common Stock shall not
then be physically delivered to the Holder.

               (b) Reservation of Shares. The Company shall at all



                                       21
<PAGE>



times reserve for issuance and/or delivery upon exercise of this Warrant such
number of shares of its Common Stock as shall be required for issuance and
delivery upon exercise of this Warrant.

               (c) Fractional Shares. No fractional shares or script
representing fractional shares shall be issued upon the exercise of this
Warrant. All fractional shares shall be eliminated by rounding any fraction up
to the nearest whole number of shares of Common Stock.

               (d) Exchange, Transfer, Assignment or Loss of Warrant. Subject to
the legend first appearing above, this Warrant is exchangeable, without expense,
at the option of the Holder, upon presentation and surrender hereof to the
Company or at the office of its stock transfer agent, if any, for other warrants
of different denominations entitling the Holder thereof to purchase in the
aggregate the same number of shares of Common Stock purchasable hereunder.
Subject to the legend first appearing above, upon surrender of this Warrant to
the Company at is principal office or at the office of its stock transfer agent,
if any, with the Assignment Form annexed hereto duly executed and funds
sufficient to pay any transfer tax, the Company shall, without charge, execute
and deliver a new Warrant in the name of the assignee named in such instrument
of assignment and this Warrant shall promptly be canceled. This Warrant may be
divided or combined with other Warrants which carry the same rights upon
presentation hereof at the principal office of the Company or at the office of
its stock transfer agent, if any, together with a written notice specifying the
names and denominations in which new Warrants are to be issued and signed by the
Holder hereof. The term "Warrant" as used herein includes any Warrant into which
this Warrant may be divided or exchanged. Upon receipt by the Company of
evidence satisfactory to it of the loss, destruction) of reasonably satisfactory
indemnification, and upon surrender and cancellation of this Warrant, if
mutilated, the Company will execute and deliver a new Warrant of like tenor and
date.

               (e) Rights of the Holder. The Holder shall not, by virtue hereof,
be entitled to any rights of a shareholder in the Company, either at law or
equity, and the rights of the Holder are limited to those expressed in this
Warrant and are not enforceable against the Company except to the extent set
forth herein.

               (f) Anti-Dilution Provisions. The Exercise Price in effect at any
time and the number and kind of securities purchasable upon the exercise of this
Warrant shall be subject to adjustment from time to time upon the happening of
certain events as follows:

                      (1) In case the Company shall (i) declare a dividend or
make a distribution on its outstanding shares of Common Stock in shares of
Common Stock, or (ii) subdivide or reclassify its outstanding shares of Common
Stock into a greater




                                       22
<PAGE>



number of shares of Common Stock or into a smaller number of shares, the
Exercise Price immediately prior to such adjustment shall be adjusted by
multiplying it by a fraction, the denominator of which shall be the number of
shares of Common Stock outstanding after giving effect to such action, and the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such action. Such adjustment shall be made successively
whenever any event listed above shall occur.

                      (2) Whenever the Exercise Price payable upon exercise of
each Warrant is adjusted pursuant to Subsection (1) above, the number of shares
purchasable upon exercise of this Warrant shall simultaneously be adjusted by
multiplying the number of shares initially issuable upon exercise of this
Warrant by the Exercise Price in effect on the date hereof and dividing the
product so obtained by Exercise Price, as adjusted.

                      (3) Whenever the Exercise Price is adjusted, as herein
provided, the Company shall promptly cause a notice setting forth the adjusted
Exercise Price and adjusted number of shares issuable upon exercise of each
Warrant to be mailed to the Holders, at their last addresses appearing in the
Warrant Register, and shall cause a certified copy thereof to be mailed to its
transfer agent, if any. The Company may retain a firm of independent certified
public accountants selected by the Board of Directors (who may be the regular
accountants employed shall be conclusive evidence of the correctness of such
adjustment.

               (g) Officer's Certificate. Whenever the Exercise Price shall be
adjusted as required by the provisions of Section (f), the Company shall
forthwith file in the custody of its Secretary or an Assistant Secretary at its
principal office and with its stock transfer agent, if any, an officer's
certificate showing the adjusted Exercise Price determined as herein provided,
setting forth in reasonable detail the facts requiring such adjustment,
including a statement of the number of additional shares of Common Stock, if
any, and such other facts as shall be necessary to show the reason for and the
manner computing such adjustment.

               (h) Notices to Warrant Holders. So long as this Warrant shall be
outstanding, (1) if the Company shall pay any dividend or make any distribution
upon the Common Stock or (2) if the Company shall offer to the holders of Common
Stock for subscription or purchase by them any share of any class or any other
rights or (3) if the capital reorganization of the Company, reclassification or
merger of the Company with or into another corporation, sale of all or
substantially all of the property and assets of the Company or voluntary or
involuntary dissolution, liquidation or winding up of the Company shall be
effected, then in any such case, the Company shall cause to be mailed by
certified mail to the Holder, at least ten (10) days prior to the date specified
in (x) or (y) below, as the case may be, a notice



                                       23
<PAGE>


containing a brief description of the proposed action and stating the date on
which (x) a record is to be taken for the purpose of such dividend, distribution
or rights, or (y) such reclassification, reorganization, consolidation, merger,
conveyance, lease, dissolution, liquidation or winding up is to take place and
the date, if any, is to be fixed, as of which the holders of Common Stock or
other securities shall receive cash or other property deliverable upon such
reclassification, reorganization, consolidation, merger, conveyance,
dissolution, liquidation or winding up.

               (i) Piggyback Registration. If, at any time commencing after the
date hereof until such time as the Holder has sold or otherwise disposed all of
the Warrant Shares, the Company proposes to register any of its equity
securities under the Act (other than in connection with a merger or
consolidation or pursuant to a Registration Statement on Form S-3 or S-4 or
comparable registration statement) it will give written notice, at least thirty
(30)days prior to the filing of such registration statement, to the Holder and
to all other holders of Warrants and Warrant Shares (collectively, "Warrant
Securities") of its intention to do so. If the Holder and/or other holders of
Warrant Securities notify the Company within twenty (20) days after receipt of
such notice of its or their desire to include any Warrants (including the shares
of Common Stock underlying any such Warrants) and/or Warrant Shares (whether
issued or issuable) in such proposed registration statement, the Company shall,
subject to the provisions set forth below, afford the Holder and such holders of
Warrant Securities the opportunity to have any such securities registered under
such registration statement. If such registration is an underwritten
registration, and the managing underwriters advise the Company that in their
opinion the number of securities requested to be included in such registration
exceeds the number which can be sold in such offering without materially
adversely affecting such underwriters' ability to effect an orderly distribution
of such securities, the Company will include in such registration first, the
securities proposed to be sold thereunder and, second, the Warrant Securities
and such other securities of the Company having registration rights requested to
be included in such registration registered on a pro-rata basis. The Company
shall have the right at any time thereafter it shall give written notice to
elect not to file any such proposed registration statement or to withdraw the
same after filing but prior to the effective date thereof. The Company shall pay
all such expenses relating to registration except sales commissions attributable
to Warrant Securities requested to be offered by the holders thereof and except
expenses incurred by the holders such as counsel for the holders. Such sales
commissions and other such expenses will be borne by the holders requesting
inclusion in such registration.

               (j) Indemnification. In the event Warrant Securities are included
in a registration statement by the Company, the



                                       24
<PAGE>


Company will indemnify and hold harmless each holder of registered Warrant
Securities against all claims and losses arising out of securities law
violations by the Company and each holder of registered Warrant Securities will
indemnify and hold harmless the Company against all claims and losses arising
out of the information supplied to the Company by such holder for use in
connection with such registration.

               (k) Reclassification, Reorganization or Merger. In case of any
reclassification, capital reorganization or other change of outstanding shares
of Common Stock of the Company, or in case of any consolidation or merger of the
Company with or in which merger the Company is the continuing corporation and
which does not result in any reclassification, capital reorganization or other
change of outstanding shares of Common Stock of the class issuable upon exercise
of this Warrant or in case of any sale to another corporation of the property of
the Company as an entirety, the Company shall, as a condition precedent to such
transaction, cause effective provisions to be made so that the Holder shall have
the right thereafter by exercising this Warrant at any time prior to the
expiration of the Warrant, to purchase the kind and amount of shares upon
exercise of this Warrant immediately prior to such reclassification, change,
consolidation, merger or sale. Any such transaction shall include provision for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Warrant. The foregoing provisions of this
Section (k) shall similarly apply to successive reclassifications, capital
reorganizations and changes of shares of Common Stock and to successive
consolidations, mergers or sales. In the event that in connection with any such
capital reorganization, a share of Common Stock shall be issued in exchange,
conversion, substitution or payment, in whole or in part, for a security of the
Company other than Common Stock, any such issue shall be treated as an issue of
Common Stock covered by the provisions of Subsection (1) of Section (f) hereof.

               (l) Redemption.

                      (1) Commencing one year after the date hereof (the
"Initial Warrant Redemption Date") the Company may, on 30 days prior written
notice redeem all the Warrants at $0.01 provided, however, that before any such
call for redemption of Warrants can take place, the (A) high closing bid price
for the Common Stock in the over-the-counter market as reported by the National
Association of Securities Dealers Automated Quotation System ("NASDAQ") or (B)
the closing sale price on the primary exchange on which the Common Stock is
traded, if the Common Stock is traded on a national securities exchange or if
the Common Stock is a National Market Security on NASDAQ, shall have for five
(5) consecutive trading days within a period of thirty (30) consecutive trading
days ending on the fifth trading day prior to the date on which the notice
contemplated by (2)and (3) below is given, equaled or exceeded $0.75 per share
(subject to adjustment



                                       25
<PAGE>



in the event of any stock splits or other similar events as provided in Section
(f) hereof).

                      (2) In case the Company shall exercise its right to redeem
all of the Warrants, it shall give or cause to be given notice to the registered
Holders of the Warrants by mailing to such registered Holders a notice of
redemption, first class, postage prepaid, at their last address as shall appear
on the records of 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.

                      (3) The notice of redemption shall specify (i) the
redemption price, (ii) the date fixed for redemption, which shall in no event be
less than thirty (30) days after the date of mailing of such notice, (iii) the
place where the Warrant Certificate shall be delivered and the redemption price
shall be paid and (iv) that the right to exercise the 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 the Warrants 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 Holder (a) to whom notice was not mailed or (b) w 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.

                      (4) Any right to exercise a Warrant shall terminate at
5:00 p.m. (New York time) on the business day immediately preceding the
