                                  RISK FACTORS

This offering involves a high degree of risk. You should carefully  consider the
risks  described  below and the other  information  contained in this Prospectus
before deciding to invest in shares of our common stock.

THE COMPANY MAY NOT HAVE SUFFICIENT CASH FOR ITS CURRENT OPERATIONS.

The Company has a working capital deficit, which was approximately $2.33 million
at June 30, 2003.  For the balance of calendar  year 2003,  the  Company's  cash
requirements are expected to include  primarily the funding of operating losses,
the payment of outstanding  accounts  payable and the repayment of certain notes
payable.  The  Company  is  seeking  additional  capital  and  plans to raise an
additional $3,000,000 during the remainder of calendar 2003. However,  there can
be no assurance that these financings will be achieved. If these financings were
achieved,   the  Company  would  be  able  to  fund  current   operations  until
profitability  or cash  flow  breakeven,  but only if its  projected  sales  are
achieved.  Thereafter  it will need  additional  funds for  operations,  product
expansion and debt repayment.

In the event of  unforeseen  circumstances  affecting  the  economy  and/or  the
Company,  this cash flow  projection may be proven  inaccurate,  and the Company
will need additional funds for current operations as well as for its outstanding
obligations sooner than currently anticipated. The Company can give no assurance
that  sources  of funds  will be  available  to fund its  operations  and  other
obligations.  If financing is  unavailable,  it may default on its  obligations,
curtail operations or cease business altogether.


WITH RECENTLY REDUCED PERSONNEL, THE COMPANY MAY NOT BE ABLE TO OPERATE AT AN
ADEQUATE LEVEL.

Current  economic  conditions  have imposed  significant  constraints on capital
raising  and have  caused  projections  of  operating  revenues to remain at the
current  lower level for the  balance of Fiscal  Year 2003.  In response to such
economic conditions, the Company recently reduced personnel, including employees
in marketing  and  employees in research  and  development.  The effect of these
recent personnel  reductions on the Company's future sales and operations cannot
yet be determined at this time.


THE COMPANY HAS A SUBSTANTIAL LEVEL OF INDEBTEDNESS AND IF IT IS UNABLE TO RAISE
NEW CAPITAL OR GENERATE SUFFICIENT CASH FROM OPERATIONS IT WILL NOT BE ABLE TO
FULFILL ITS FINANCIAL OBLIGATIONS.

The Company has approximately  $1.6 million of debt, some of which is classified
as short  term.  If the  Company is not able to raise new capital or to generate
enough  cash  from  operations,  it will  not be able  to pay  the  interest  on
outstanding  debt and repay any scheduled  payments of principal.  In that event
the Company may be in default  and, as a  consequence,  it may have to refinance
some or all of the debt,  obtain  other  sources  of  capital,  which may not be
available at that time, or continue in default.  Any  refinancing  or additional
capital, if available, might be on unfavorable terms in those circumstances. Any
default on the Company's financial obligations would likely force curtailment or
halting of operations or liquidation of assets.


WE HAVE SUSTAINED LOSSES IN THE PAST AND WE EXPECT TO REPORT LOSSES IN THE
FUTURE; GOING CONCERN QUALIFICATION IN REPORT OF INDEPENDENT CERTIFIED PUBLIC
ACCOUNTANTS.

We have incurred  substantial  losses that have reduced our stockholders  equity
and at times  depleted our working  capital.  We funded our negative  cash flows
from 1999 to date  primarily by the sale of additional  equity and the placement
of debt. We incurred  losses of  approximately  $4.15 million during fiscal year
2002 and losses of $3.8 million  during the first three  quarters of fiscal year
2003.

The losses in fiscal year 2002 were incurred primarily from expenses  associated
with the marketing of the new drug-testing kits and the development of test kits
for diseases.  Current economic conditions have imposed significant  constraints
on capital  raising and have caused actual and projected  operating  revenues to
remain at a lower than expected level for the balance of Fiscal Year 2003.

As a result of the  Company's  recurring  losses  from  operations  and  working
capital  deficit,  the report of its independent  certified  public  accountants
relating  to  the  financial   statements  for  fiscal  year  2002  contains  an
explanatory  paragraph stating  substantial doubt about the Company's ability to
continue as a going  concern.  Such report  states that the ultimate  outcome of
this matter could not be determined as of the date of such report  (November 26,
2002). Currently, it is anticipated that this consideration will be reflected in
the report on the financial  statements for the fiscal year ended  September 30,
2003.

PRINCIPAL SUPPLIER RISK

Suppliers of two key  components  are, in each case, the current sole source for
the Company.  The inability to obtain  components will have an adverse effect on
the business, revenues and prospects of the Company. Although the Company has an
inventory  of these  components,  it may not last  sufficiently  long  while the
Company finds a new supplier.  There is no assurance that a new supplier will be
found for these components on a timely basis, or at all, if the current supplier
ceases to sell to the Company.

Although some of the parts and components  used to manufacture  our products are
available from multiple  sources,  we currently  purchase most of our components
from  single  sources  in  an  effort  to  obtain  volume  discounts.   Lack  of
availability  of any of these parts and  components  could result in  production
delays,  increased  costs,  or  costly  redesign  of our  products.  Any loss of
availability of an essential system component could result in a material adverse
change to our business, financial condition and results of operations.

WITH ALL OF OUR ASSETS PLEDGED TO PRIOR SENIOR LENDERS, THE COMPANY MAY NOT BE
ABLE TO BORROW FUNDS AND HAVE TO CURTAIL OR CEASE OPERATIONS.

The Company has  pledged  substantially  all of its assets as security to Senior
Lenders for currently  outstanding  debt of approximately  $1.4 million.  If the
Company falls into default to the Senior Lenders, there likely will be no assets
available for the repayment of the outstanding  Notes issued in February 2003 or
any subsequent debt. In addition,  the Company has no other assets to pledge for
additional  debt and  requires  the consent of the Senior  Lenders for a further
security  interest to be placed on any of the pledged  assets.  The inability of
the  Company to borrow in the  future  may cause the  Company to cut back on its
operations.

NO ASSURANCE  FUTURE  CAPITAL WILL BE AVAILABLE TO US;  ADDITIONAL  CAPITAL WILL
DILUTE THE HOLDINGS OF OUR STOCKHOLDERS.

If we need  additional  financing,  we cannot give any assurance that it will be
available, or if available,  that it will be available on terms favorable to our
stockholders.  If funds are not available to satisfy any of our  short-term  and
long-term operating requirements,  we may limit or suspend our operations in the
entirety or, under certain  circumstances,  seek protection from creditors.  Our
recent  equity  offerings   resulted  in  the  dilution  of  our  then  existing
stockholders. It is possible that future financings may contain terms that could
result in similar or more substantial dilution than has already been incurred by
our stockholders from the sales of equity with warrants since fiscal year 1998.

A  SIGNIFICANT  NUMBER OF OUR SHARES ARE  ELIGIBLE FOR SALE AND THEIR SALE COULD
FURTHER DEPRESS THE MARKET PRICE OF OUR STOCK.

Sales of substantial  amounts of our common stock (including  shares issued upon
exercise of outstanding  options and warrants and shares issued upon  conversion
of convertible preferred shares and debt) in the public market could depress the
market price of our common stock. As of August 12, 2003, we had approximately 85
million shares  outstanding  and  approximately  25 million shares  committed or
reserved for issuance  upon  exercise of options and warrants or  conversion  of
convertible preferred shares.

WE DEPEND ON THE DRUG OF ABUSE  SCREEN  SYSTEMS AND MARKET  ACCEPTANCE  OF THOSE
SYSTEMS IS UNCLEAR.

We intend to continue to concentrate our efforts primarily on the development of
the ORALscreen drug of abuse detection systems and we will be dependent upon the
successful development and marketing of those systems to generate revenues.
Acceptance of our systems may be adversely affected by:

- -    costs,

- -    concerns related to accuracy or false positive reports,

- -    a cultural resistance to the use of drug of abuse screening tests,

- -    the effectiveness of competing drug of abuse screening tests.

Any failure to achieve  greater  market  acceptance  of our systems  will have a
material  adverse  effect on our  business,  financial  condition and results of
operations.

THE  SUCCESS  OF  COMPETITIVE  PRODUCTS  COULD  HAVE AN  ADVERSE  EFFECT  ON OUR
BUSINESS.

The Drug of Abuse Testing industry is intensely competitive, although at present
we have encountered only minimal direct competition in the rapid on-site (as
opposed to laboratory) oral fluid drug testing market. The significant
competitive factors in the industry include:

- -    price,

- -    convenience,

- -    accuracy,

- -    acceptance of new technologies,

- -    user satisfaction, and

- -    when applicable, government approval.

We believe our ORALscreen systems offer several distinct advantages over the use
of  blood  or  urine  samples,  including  net  cost  savings,  ease  of use and
non-invasiveness.  However,  the  success of any  competing  alternative  to the
ORALscreen  systems  for  screening  for drugs of abuse  could  have a  material
adverse effect on our business,  financial  condition and results of operations.
Most of our competitors have  substantially  greater financial  capabilities for
product  development  and  marketing  than  we  currently  do.  These  financial
capabilities  enable our competitors to market their systems in a more effective
manner.

SUBSTANTIAL REGULATION BY GOVERNMENT AGENCIES.

Many  of  our  products  are  subject  to   regulation  by  the  Food  and  Drug
Administration (the "FDA") and comparable agencies in various states and foreign
countries requiring, among other things, pre-market approval or clearance of new
medical or dental devices. In November 2000, the FDA proposed  regulations that,
although still not in effect, in the future may require a pre-market approval or
clearance of our ORALscreen products for sale to employers. In addition,  Avitar
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 and/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.  Such  submissions  and review by the FDA could take
several  years,  after which there could be no assurance  that approval would be
granted.

DEPENDENCE ON INTELLECTUAL PROPERTY; NO ASSURANCE AS TO PROTECTION OF
INTELLECTUAL PROPERTY.

Our ability to compete effectively with other companies will depend, in part, on
our ability to maintain the proprietary nature of our technologies. We intend to
rely substantially on unpatented proprietary information and know-how, and there
can be no assurance that others will not develop such  information  and know-how
independently or otherwise obtain access to our technology. Similarly, there can
be no assurance that our  proprietary  technology  will not infringe  patents or
other  rights  owned by others.  If we are unable to  adequately  safeguard  and
exploit  our  methods  and  technologies,  our  ability  to  compete  with other
companies, a majority of which have greater financial,  technological, human and
other  resources than the Company,  our business  would be materially  adversely
affected.

RISK OF PRODUCT LIABILITY; LIMITED INSURANCE COVERAGE.

The testing, marketing and sale of medical and dental products entails a risk of
product liability claims by consumers and others.  Avitar has maintained product
liability  insurance  coverage and currently has such insurance in the amount of
up to $5,000,000.  This insurance  will not cover  liabilities  caused by events
occurring after such policy is terminated or claims made after 60 days following
termination of the policy or in respect of events excluded from coverage. In the
event of a successful suit against Avitar,  lack or  insufficiency  of insurance
coverage  would  have a material  adverse  effect on  Avitar.  Further,  certain
distributors  of medical and dental products  require minimum product  liability
insurance coverage as a condition  precedent to purchasing or accepting products
for distribution.  Failure to satisfy such insurance  requirements  could impede
the ability of Avitar to achieve broad distribution of its products, which would
have a material adverse effect on Avitar.

WE ARE DEPENDENT ON OUR MANAGEMENT AND KEY PERSONNEL TO SUCCEED.

Our principal  executive officers and key personnel have extensive  knowledge of
and experience with our products, the research and development efforts needed to
improve them and the  development  of marketing  and sales  programs to increase
their  market  penetration.  The loss of the  services  of any of our  executive
officers or other key  personnel,  or our  failure to attract  and retain  other
skilled and experienced  personnel,  could have a material adverse effect on our
ability to manufacture, sell and market our products. Such events would probably
have a negative impact on our business and financial condition.

Barriers to takeover

The Company is governed by the provisions of Section 203 of the Delaware General
Corporation  Law, an anti-takeover  law. In general,  the law prohibits a public
Delaware  corporation  from  engaging  in  a  "business   combination"  with  an
"interested  stockholder"  for a period  of three  years  after  the date of the
transaction  in which the person  became an interested  stockholder,  unless the
business combination is approved in a prescribed manner.  "Business combination"
is  defined to include  mergers,  asset  sales and  certain  other  transactions
resulting  in  a  financial   benefit  to  the   stockholders.   An  "interested
stockholder"  is  defined  as  a  person  who,   together  with  affiliates  and
associates,  owns (or within the prior  three  years,  did own) 15% or more of a
corporation's  voting  stock.  As a result of the  application  of Section  203,
potential  acquirers of the Company may be discouraged from attempting to effect
an acquisition transaction with the Company,  thereby possibly depriving holders
of the  Company's  securities  of  certain  opportunities  to sell or  otherwise
dispose of such securities at above market prices pursuant to such transactions.
In  addition,  in the event of certain  changes of  control of the  Company  (as
defined in the Company's  Equity Plan)  outstanding  options granted pursuant to
the Company's  Equity Plan will become  immediately  exercisable  in full.  Such
acceleration of exercisability  may also discourage  potential  acquirers of the
Company.

THE MARKET PRICE OF OUR STOCK HAS HISTORICALLY BEEN VOLATILE.

The  volatility of our common stock imposes a greater risk of capital  losses on
stockholders as compared to less volatile stocks.  In addition,  such volatility
makes it difficult to ascribe a stable valuation to a stockholder's  holdings of
our common stock.  Factors such as announcements  of technological  innovations,
changes in marketing,  product  pricing and sales  strategies or new products by
our  competitors,  changes in 2domestic or foreign  governmental  regulations or
regulatory  approval  processes,  developments or disputes relating to patent or
proprietary  rights and public  concern as to the  reliability of the OralScreen
systems  or drug tests in general  may have a  significant  impact on the market
price of our common  stock.  Moreover,  the  possibility  exists  that the stock
market (and in particular the  securities of technology  companies such as ours)
could experience  extreme price and volume  fluctuations  unrelated to operating
performance.



RECENT DEVELOPMENTS CONCERNING GOODWILL AND OTHER INTANGIBLE ASSETS

     Effective  October 1, 2002, the Company adopted SFAS No. 142,  Goodwill and
Other Intangible  Assets,  during Fiscal 2003. SFAS No. 142 requires among other
things,  that  companies  no longer  amortize  goodwill,  but test  goodwill for
impairment at least  annually.  In addition,  SFAS 142 requires that the Company
identify  reporting  units  for  the  purpose  of  assessing   potential  future
impairments of goodwill,  reassess the useful lives of other existing recognized
intangible   assets,  and  cease  amortization  of  intangible  assets  with  an
indefinite  useful life.  An  intangible  asset with an  indefinite  useful life
should be tested for impairment in accordance  with guidelines in SFAS 142. SFAS
142 is  required  to be  applied to all  goodwill  and other  intangible  assets
regardless  of when those  assets were  initially  recognized.  As of October 1,
2002, the Company's goodwill of $2,139,555 was composed of $1,901,435 associated
with  the  acquisition  of  USDTL  in 1999  and  $238,120  associated  with  the
acquisition of BJR in 2001. As a result of the  transitional  impairment  tests,
the  USDTL   acquisition  was  determined  to  be  impaired  by  an  independent
evaluations  which relied on present value of future cash flows  contained in an
offer to purchase  USDTL and market price  comparisons  of sales  multiples  for
companies  engaged in a similar  business to USDTL.  The  difference in value of
$650,000 is being  reported  as the  cumulative  effect of change in  accounting
principle  for the period ended June 30,  2003.  No  adjustment  to the $238,120
balance of goodwill  associated with the BJR acquisition was deemed necessary as
of June 30, 2003.

         The effect on reported net loss due to the cumulative effect of change
in accounting principle and discontinuance of goodwill amortization is as
follows:

                                 USE OF PROCEEDS

     We will not receive any proceeds from the sale of shares of common stock by
the selling  security  holders.  The Company could  receive up to  approximately
$800,000 if all outstanding warrants were exercised.  The Company intends to use
the proceeds, if any, to provide general working capital.  However, there can be
no assurance that these outstanding warrants will be exercised.

                              PLAN OF DISTRIBUTION

We are registering the common stock,  including the common stock  underlying the
warrants  and  the  shares  of   preferred   stock  on  behalf  of  the  selling
stockholders.  The common stock may be sold in one or more transactions at fixed
prices,  at prevailing  market prices at the time of sale, at prices  related to
the prevailing  market prices, at varying prices determined at the time of sale,
or at negotiated prices.  These sales may be effected at various times in one or
more of the following transactions, or in other kinds of transactions:

     -    transactions  on  the  American  Stock  Exchange  or on  any  national
          securities  exchange  or  U.S.  inter-dealer  system  of a  registered
          national  securities  association  on which  the  common  stock may be
          listed or quoted at the time of sale;

     -    in the over-the-counter market;

     -    in  private  transactions  and  transactions  otherwise  than on these
          exchanges or systems or in the over-the-counter market;

     -    in connection with short sales of the shares;

     -    by pledge to secure or in payment of debt and other obligations;

     -    through the  writing of options,  whether the options are listed on an
          options exchange or otherwise;

     -    in connection with the writing of non-traded and exchange-traded  call
          options, in hedge transactions and in settlement of other transactions
          in standardized or over-the-counter options; or

     -    through a combination of any of the above transactions.

     The selling stockholders and their successors, including their transferees,
pledgees or donees or their  successors,  may sell the common stock  directly to
the  purchasers  or through  underwriters,  broker-dealers  or  agents,  who may
receive  compensation in the form of discounts,  concessions or commissions from
the selling  stockholders or the  purchasers.  These  discounts,  concessions or
commissions as to any particular  underwriter,  broker-dealer or agent may be in
excess of those customary in the types of transactions involved.

     In addition,  any securities  covered by this prospectus  which qualify for
sale  pursuant  to Rule 144 of the  Securities  Act may be sold  under  Rule 144
rather than pursuant to this prospectus.

     We entered  into  registration  rights  agreements  for the  benefit of the
selling  stockholders to register the common stock under applicable  federal and
state  securities  laws.  The  registration   rights   agreements   provide  for
cross-indemnification  of the  selling  stockholders  and us and our  respective
directors,  officers and  controlling  persons against  specific  liabilities in
connection  with the offer and sale of the common stock,  including  liabilities
under the Securities Act. We will pay substantially all of the expenses incurred
by the selling  stockholders  incident to the  registration  of the offering and
sale of the common stock.

     The selling stockholders and any other persons participating in the sale or
distribution  of the  shares  will be subject to  applicable  provisions  of the
Exchange Act and the rules and regulations  under such act,  including,  without
limitation,  Regulation M. These provisions may restrict certain  activities of,
and limit the timing of purchase  and sales of any of the shares by, the selling
stockholders or any other such person. Furthermore,  under Regulation M, persons
engaged in a  distribution  of securities  are  prohibited  from  simultaneously
engaging in market  making and certain  other  activities  with  respect to such
securities  for a  specified  period of time prior to the  commencement  of such
distributions,  subject to  specified  exceptions  or  exemptions.  All of these
limitations may affect the marketability of the shares.

                                     EXPERTS

     The financial  statements  incorporated in this  Registration  Statement by
reference to the Annual  Report on Form 10-KSB for the year ended  September 30,
2002 have been so  incorporated  in reliance on the report of BDO Seidman,  LLP,
independent certified public accountants, given on the authority of said firm as
experts in auditing and accounting.


                                  LEGAL MATTERS

     Certain legal matters with respect to the validity of the common stock will
be passed upon for Avitar by Dolgenos Newman & Cronin LLP, New York, New York.

                          STATEMENT OF INDEMNIFICATION

     The Company's  Certificate of  Incorporation,  as amended,  provides that a
director will not be personally  liable to the Company or its  stockholders  for
monetary  damages  for  the  breach  of his or her  fiduciary  duty of care as a
director,  including breaches that constitute gross negligence. By its terms and
in accordance with the Delaware General Corporation Law ("DGCL"),  however, this
provision does not eliminate or limit the liability of a director of the Company
(i)  for  breach  of the  director's  duty  of  loyalty  to the  Company  or its
stockholders,  (ii) for acts or  omissions  not in good  faith or which  involve
intentional misconduct or a knowing violation of law, (iii) under Section 174 of
the  DGCL  (relating  to  unlawful  payments  of  dividends  or  unlawful  stock
repurchases or redemptions) or (iv) for any improper benefit.

     This  provision  offers  persons  who  serve  on  our  board  of  directors
protection  against awards of monetary damages  resulting from breaches of their
duty of care (except as indicated  above).  As a result of this  provision,  our
ability or our stockholder's ability to successfully prosecute an action against
a director for a breach of his duty of care is limited.  However,  the provision
does not affect the availability of equitable  remedies such as an injunction or
rescission based upon a director's breach of his duty of care. The SEC has taken
the position  that the  provision  will have no effect on claims  arising  under
federal securities laws.

     Section 145 of the Delaware law grants  corporations the right to indemnify
their  directors,   officers,  employees  and  agents  in  accordance  with  the
provisions  therein set forth.  Our By-laws  provide  that we shall,  subject to
limited  exceptions,  indemnify  our  directors  and  executive  officers to the
fullest extent not prohibited by the Delaware Law. Our By-laws  provide  further
that we shall have the power to  indemnify  our other  officers,  employees  and
other  agents as set forth in the  Delaware  law.  Such  indemnification  rights
include reimbursement for expenses incurred by such director, executive officer,
other  officer,  employee or agent in advance of the final  disposition  of such
proceeding in accordance with the applicable provisions of the Delaware law.

     We have entered into  agreements with certain of our directors and officers
pursuant to which we have agreed to indemnify such directors and officers to the
fullest extent  permitted under  applicable law. In addition,  we have purchased
insurance  containing  customary  terms and  conditions  as  permitted by law on
behalf of its  directors  and officers,  which may cover  liabilities  under the
Securities Act.  Insofar as  indemnification  for liabilities  arising under the
Securities  Act may be permitted  to our  directors,  officers  and  controlling
persons  pursuant to these  provisions,  or  otherwise,  Avitar has been advised
that, in the opinion of the SEC, such  indemnification  is against public policy
as expressed in the Securities Act and is, therefore, unenforceable.
