                               PROSPECTUS SUMMARY

         This summary highlights information about the offering and Advanced
Viral Research Corp. which we believe will be most important to you. However,
you should read the entire prospectus for a complete understanding of the
offering and our business.

ADVANCED VIRAL RESEARCH CORP.

         Advanced Viral Research Corp. was formed in July 1985 to engage in the
production and marketing, promotion and sale of a pharmaceutical drug with the
trade name RETICULOSE(TM) (the current formulation of which is now known as and
hereinafter referred to as PRODUCT R(TM)) for the treatment of certain viral
diseases such as:

         o        human immunodeficiency virus, or HIV, including acquired
                  immune deficiency syndrome, or AIDS;

         o        hepatitis B and hepatis C, both liver diseases

         o        human papilloma virus, or HPV, which causes genital warts and
                  may lead to cervical cancer; and

         o        rheumatoid arthritis.

         Since 1962, when Reticulose was reclassified as a "new drug" by the
Food and Drug Administration, or FDA, the FDA has not permitted Reticulose to be
marketed in the United States. A forfeiture action was instituted in 1962 by the
FDA against Reticulose, and it was withdrawn from the United States market. The
injunction obtained by the FDA prohibits, among other things, any shipment of
Reticulose, now known as "Product R," until a new drug application, or NDA, is
approved by the FDA. FDA approval of an NDA first requires clinical testing of
Product R in human trials, which cannot be conducted until we first satisfy the
regulatory protocols and the substantial preapproval requirements imposed by the
FDA upon the introduction of any new or unapproved drug product pursuant to a
notice of claimed investigational exemption for a new drug, or IND.

         Our operations over the last five years have been limited principally
to research, testing and analysis of Product R in the United States, either IN
VITRO (outside the living body in an artificial environment, such as in a test
tube), or on animals, and engaging others to perform testing and analysis of
Product R on human patients outside the United States.

         Shalom Z. Hirschman, M.D., our President, has monitored the testing of
Product R and has recently performed analyses of Product R with our laboratory
personnel, which we believe may be used in connection with the FDA approval
process. In addition, we have contracted with GloboMax LLC of Hanover, Maryland
to advise us in our preparation and filing of an IND with the FDA, and to
otherwise assist us through the FDA process with the objective of obtaining full
approval for the manufacture and commercial distribution of Product R in the
United States.

         Our offices are located at 200 Corporate Boulevard South, Yonkers, New
York 10701 and 1250 East Hallandale Beach Boulevard, Suite 501, Hallandale,
Florida 33009. Our telephone number in Yonkers, New York is (914) 376-7383 and
our telephone number in Hallandale, Florida is (954) 458-7636.

RECENT DEVELOPMENTS

         On September 18, 2000, we signed a private equity line of credit
agreement with Spinneret Financial Systems, Inc. for the future issuance and
purchase of shares of our common stock. The private equity line of credit
agreement establishes what is sometimes termed an equity line of credit or an
equity drawdown facility. Spinneret has committed up to $20 million to purchase
shares of our common stock. Beginning on the date that a registration statement
covering the resale of the shares issuable pursuant to the equity line of credit
is declared effective by the Commission, and continuing for thirty (30) months
thereafter, we may, from time to time, in our sole discretion, sell or "put"
shares of our common stock to Spinneret at a price equal to the market price of
the common stock. Spinneret's obligation to purchase the shares of our common
stock is subject to the satisfaction of the conditions included on page 31 of
this prospectus. Once every fifteen (15) trading days, we may request an advance
the maximum amount of which is dependent among other things, on the trading
volume of our common stock. The number of shares that we will issue to Spinneret
in return for the advance will be determined by dividing the amount of the
advance by the average of the three lowest reported closing bid prices of our
common stock over a 25 trading day period ending on the advance notice date, as
set forth in private equity line of credit agreement.

         We will receive the amount of the advance less any escrow agent fees
and a five percent (5%) cash placement fee payable to the placement agent, May
Davis Group, Inc., which introduced Spinneret to us. May Davis is not obligated
to purchase any of our shares, but as an additional placement fee, we have
issued to May Davis a Class A Warrant to purchase 5,000,000 shares of our common
stock at an exercise price per share equal to $1.00, exercisable in part or in
whole at any time by May Davis at its discretion until September 18, 2005, and a
Class B Warrant to purchase 5,000,000 shares of our common stock at an exercise
price equal to the greater of $1.00 or 110% of the bid price of the common stock
on the applicable advance date, exercisable pro rata on the basis of the number
of shares of common stock issuable on each advance date for a period of sixty
months from the date of issuance. We may redeem the warrants at a redemption
price of $.01 per share provided that the bid price for our common stock equals
at least $4.00 per share for a period of ten (10) consecutive trading days, as
described therein. May Davis is also entitled to certain "piggyback"
registration rights with respect to the shares of common stock issuable upon
exercise of the warrants pursuant to a registration rights agreement.

         In addition, pursuant to the equity line of credit agreement, each
officer, director and affiliate of Advanced Viral has agreed that he, she or it
will not, directly or indirectly, without the prior written consent of
Spinneret, issue, offer, agree or offer to sell, sell, grant an option for the
purchase or sale of, transfer, pledge, assign, hypothecate, distribute or
otherwise encumber or dispose of (whether pursuant to Rule 144 promulgated under
the Securities Act of 1933, as amended, or otherwise) any shares of our common
stock, including options, rights, warrants or other securities underlying,
convertible into, exchangeable or exercisable for or evidencing any right to
purchase or subscribe for any shares of our common stock (whether or not
beneficially owned by the undersigned), or any beneficial interest therein for a
period of ten (10) trading days following the receipt of an advance notice by
Advanced Viral pursuant to the agreement.

                                  RISK FACTORS

         OUR SECURITIES ARE HIGHLY SPECULATIVE. YOU SHOULDN'T PURCHASE THEM
UNLESS YOU CAN AFFORD TO LOSE YOUR ENTIRE INVESTMENT. YOU SHOULD CONSIDER VERY
CAREFULLY THE FOLLOWING RISK FACTORS BEFORE YOU DECIDE TO PURCHASE OUR
SECURITIES.

1.       BECAUSE OUR SHARES ARE `PENNY STOCKS,' YOU MAY BE UNABLE TO RESELL THEM
         IN THE SECONDARY MARKET.

         A "penny stock" is an equity security with a market price of less than
$5 per share which is not listed on the Nasdaq or a national securities
exchange. Due to the extra risks involved in an investment in penny stocks,
federal securities laws and regulations require broker/dealers who recommend
penny stocks to persons other than their established customers and accredited
investors to make a special written suitability determination for the purchaser,
provide them with a disclosure schedule explaining the penny stock market and
its risks, and receive the purchaser's written agreement to the transaction
prior to the sale. These requirements limit the ability of broker/dealers to
sell penny stocks. Also, because of the extra requirements, many broker/dealers
are unwilling to sell penny stocks at all. As a result, you maybe unable to
resell the stock you buy in this offering and could lose your entire investment.

2.       THE EXERCISE OR CONVERSION OF OUR OUTSTANDING CONVERTIBLE SECURITIES
         COULD HAVE A SIGNIFICANT NEGATIVE IMPACT ON THE MARKET PRICE OF OUR
         COMMON STOCK.


         As of the date of this prospectus, in addition to the 391,729,385
shares of our common stock currently outstanding, the following securities are
outstanding:

         o    Stock options to purchase an aggregate of 27,200,380 shares of
              common stock at exercise prices ranging from $0.15 to $0.36; and

         o    Warrants to purchase an aggregate of 14,698,276 shares of common
              stock at prices ranging from $0.199 to $0.864.


         If all the outstanding options, warrants, and convertible debentures
were fully exercised and converted, as the case may be, there would be
outstanding approximately an additional 65,428,656 shares of common stock. The
sale or availability for sale of this number of shares of common stock in the
public market could depress the market price of the common stock. Additionally,
the sale or availability for sale of this number of shares may lessen the
likelihood that additional equity financing will be available to us, on
favorable or unfavorable terms.



         Subject to certain volume restrictions and the requirement that there
be an effective registration statement covering the resale of the shares of
common stock to be sold, we have the ability to sell up to $20,000,000 worth of
common stock under the private equity line of credit agreement, but the timing
and amount of capital raised can vary significantly depending upon various
factors, including the market price of our common stock. We cannot be certain
that Spinneret will have the ability to purchase any of the shares of common
stock put to it pursuant to the equity line of credit agreement. Accordingly, we
may not be able to raise necessary capital in the manner we expect pursuant to
the equity line of credit agreement.


3.       IT IS UNLIKELY THAT OUR COMPANY WILL BE ABLE TO CONTINUE AS A GOING
         CONCERN WITHOUT A SIGNIFICANT IMPROVEMENT IN OUR FINANCIAL CONDITION,
         WHICH HAS CONSTRAINED OUR ABILITY TO FINANCE NECESSARY RESEARCH,
         DEVELOPMENT AND OTHER OPERATING EXPENSES AS NEEDED.

         Our independent certified public accountants' report on our
consolidated financial statements for the fiscal year ended December 31, 1999
includes an explanatory paragraph regarding our ability to continue as a going
concern. During the next 12 months, we expect to spend approximately $10,000,000
($4,000,000 of which was raised during the first quarter of fiscal 2000) to
conduct research and development related activities, including approximately
$4,000,000 related to the preparation of the IND for submission to the FDA. We
currently are

                                       4
<PAGE>   8

unable to calculate the amount we will require in additional funding to complete
the FDA approval process, including conducting clinical trials and filing the
NDA application. Our ability to continue operations is dependent upon our
continued sale of our securities for funds to meet our cash requirements, and as
a result our ability to continue as a going concern is doubtful.

         Unless we are able to generate sufficient revenue or raise additional
funds when needed, it is likely that we will be unable to continue our planned
activities, even if we are making progress with our research and development
projects. The longer the duration of the regulatory approval process, the more
unlikely it is that we will be able to raise such funds on favorable terms or at
all, or that any funds raised will be sufficient to complete the FDA approval
process to achieve our goal of commercial distribution in the United States and
elsewhere. Furthermore, there is no guarantee that approval of Product R by the
FDA or any other regulatory authority, or additional financing from the sale of
our securities, will translate into any material change in our financial
condition. The extensive delays and costs of complying with the FDA regulations
makes it unlikely that we will have adequate funds to finance the necessary
clinical studies and related costs.

4.       IF WE DO NOT OBTAIN THE FDA'S APPROVAL TO CONDUCT CLINICAL TESTS OF
         PRODUCT R IN THE UNITED STATES, WE WILL NOT BE ABLE TO COMPLETE ITS
         DEVELOPMENT AND MAY NOT BE ABLE TO SELL IT ANYWHERE.

         Product R is the only product we are developing, We will not be able to
sell it in the United States unless we submit, and the FDA approves, a new drug
application, or NDA. We must conduct clinical trials of Product R in humans
before we submit an NDA. However, we cannot begin clinical trials in the United
States until the FDA approves our notice of claimed investigational exemption
for a new drug, or IND. We have not yet submitted an IND for Product R and we
don't know if or when we will submit one. The FDA will not approve our IND if we
haven't satisfied regulatory protocols and other preapproval requirements
required for the introduction of a new or unapproved drug.

         If we submit an IND and the FDA approves it, we won't be able to begin
clinical testing unless we are able to obtain the additional financing we need
in order to conduct the trials. It is also possible that clinical trials, if
conducted, will not prove that Product R is safe or effective in treating
viruses of any kind, in which case we won't be able to submit an NDA and we
won't be able to sell Product R in the United States.

         We haven't been able to sell Product R outside the United States
because we don't have a free sales certificate for Product R. A free sales
certificate is a document issued by the country in which a pharmaceutical
product is manufactured, certifying that the country permits the "free sale" of
the product in that country. The Bahamas, where our manufacturing facility is
located, has no procedure in place to issue a free sales certificate for any
therapeutic drug, including Product R. Most countries require that a
pharmaceutical product be at least registered and certified for free sale in the
country in which it is manufactured before allowing the registration of the
product in that country. Because we are unable to obtain a certificate from the
Bahamas, we are not able to meet registration requirements in the countries
which require the certificate, and will be unable to sell Product R in those
countries.

                                       5

5.       WE HAVE INCURRED LOSSES SINCE OUR INCEPTION, HAVE NO PRODUCT REVENUE,
         AND EXPECT TO INCUR ADDITIONAL LOSSES IN THE FUTURE.

         Although we were formed in 1985, we are still in the development stage.
From inception through June 30, 2000, we had an accumulated deficit of
approximately $23,100,000. We expect that our deficit will continue to increase.
The only product revenues we have ever had are insignificant amounts related to
our distribution of Product R for testing purposes. We do not currently have any
source of product revenue. At this time we have no basis to believe that we will
ever generate operating revenues from the sale of Product R.

6.       WE DEPEND ON PATENTS AND PROPRIETARY RIGHTS, WHICH MAY OFFER ONLY
         LIMITED PROTECTION AGAINST POTENTIAL INFRINGEMENT. IF WE ARE UNABLE TO
         PROTECT OUR PATENTS AND PROPRIETARY RIGHTS, OUR BUSINESS, FINANCIAL
         CONDITION AND RESULTS OF OPERATIONS WILL BE HARMED.

         Patent protection and trade secret protection are important to our
business and that our future will depend, in part, on our ability to maintain
trade secret protection, obtain patents and operate without infringing the
proprietary rights of others both in the United States and abroad. Litigation or
other legal proceedings may be necessary to defend against claims of
infringement, to enforce our patents, or to protect our trade secrets, and could
result in substantial cost to us and diversion of our efforts. In June 2000,
Advanced Viral filed an action and complaint in the New York Supreme Court,
Westchester County, against Commonwealth Pharmaceuticals, et al alleging a
breach of an exclusive distribution agreement, misappropriation of trade secrets
and confidential information, conversion and conspiracy to convert Advanced
Viral's property interests in Reticulose. In August 2000, Commonwealth
Pharmaceuticals and certain affiliates filed a counterclaim suit against
Advanced Viral in the United States District Court for the Eastern District of
Michigan alleging ownership of the exclusive/broad rights in Reticulose, and
seeking, among other things: (i) a declaratory judgment of the claimants'
exclusive ownership of the broad/exclusive rights to Reticulose and the subject
patent; (ii) an injunction against Advanced Viral from further attempts to use,
market or assert any claims of ownership over any broad/exclusive rights in
Reticulose, or the use, publication or disclosure of information regarding
Reticulose; (iii) return of such information to the claimants; (iv) that
Advanced Viral assign any Reticulose-related trademarks to the claimants and (v)
that Advanced Viral pay damages, profits, costs and attorneys' fees. See
"Business - Legal Proceedings."


         In September 2000, our case in New York was dismissed. We are
considering requesting that the New York court reinstate our claims in the New
York case. The case in the federal court in Detroit continues. At this point, we
have answered the complaint against us in the federal court in Detroit and have
entered a number of counterclaims which are in substance the same as our claims
in the New York case.


         We currently have 15 patent applications pending with the United States
Patent and Trademark Office (the "PTO") and 17 patent applications pending in
other countries relating to Product R. In the United States, we have one allowed
patent and three issued patents from the PTO. We also rely on trade secrets,
know-how and continuing technological advancements to protect our proprietary
technology. We require all of our employees, consultants, advisors and
collaborators to enter into confidentiality agreements that prohibit the use or
disclosure of information that is deemed confidential. The agreements also
oblige our employees, consultants, advisors and collaborators to assign to us
developments, discoveries and inventions made by

                                       6
<PAGE>   10

such persons in connection with their work with us. However, these parties may
not honor these agreements and we may not be able to successfully protect our
rights to unpatented trade secrets and know-how. Others may independently
develop substantially equivalent proprietary information and techniques or
otherwise gain access to our trade secrets and know-how.

         To facilitate development of our proprietary technology base, we may
need to obtain licenses to patents or other proprietary rights from other
parties. If we are unable to obtain such licenses, our product development
efforts may be delayed.

         We may collaborate with universities and governmental research
organizations which, as a result, may acquire certain rights to any inventions
or technical information derived from such collaboration.

         We are uncertain as to whether the outcome of the aforementioned
litigation will have a material adverse impact on our business. We may incur
substantial costs in asserting any patent rights and in defending such suit and
other suits against us related to intellectual property rights. Such disputes
could substantially delay our product development or commercialization
activities. The United States Patent and Trademark Office or a private party
could institute an interference proceeding relating to our patents or patent
applications. An opposition or revocation proceeding could be instituted in the
patent offices of foreign jurisdictions. An adverse decision in any such
proceeding could result in the loss of our rights to a patent or invention.

7.       OUR BUSINESS COULD BE HARMED IF WE LOSE THE SERVICES OF THE KEY
         PERSONNEL UPON WHOM WE DEPEND.

         Advanced Viral is currently wholly dependent upon the personal efforts
and abilities of our three full-time executive officers, only one of whom,
Bernard Friedland, Chairman of the Board, has any experience in the
pharmaceutical industry. The loss or unavailability to us of the services of
Bernard Friedland or Dr. Hirschman, President and Chief Executive Officer, could
have a material negative impact on our business prospects and any potential
earning capacity, and, therefore, we have obtained "key-man" insurance on the
lives of Mr. Friedland and Dr. Hirschman in the amounts of $400,000 and
$1,000,000, respectively. If our level of operations significantly increase, the
business may depend upon our abilities to attract and hire additional management
and staff employees. It is possible that we will be unable to secure such
additional management and staff when necessary.

8.       THE VOTING CONTROL HELD BY PRESENT MANAGEMENT COULD SIGNIFICANTLY
         IMPACT OUR BUSINESS.

         As of the date of this prospectus, our current officers and directors
beneficially owned 114,009,133 shares of our common stock, or approximately
31.5% of the shares of common stock deemed outstanding on such date for the
purposes of the percentage calculation, including certain shares underlying
options held by Dr. Hirschman. As there are no cumulative voting rights, current
management, by virtue of their stock ownership, can be expected to influence
substantially the election of our board of directors and thereby continue to
impact substantially our business, affairs and policies.

OVERVIEW

         Since our inception in July 1985, we have been engaged primarily in
research and development activities. We have not yet generated significant
operating revenues, and as of June 30, 2000 we had incurred a cumulative net
loss of approximately $23,100,000. Our ability to generate substantial operating
revenue depends upon our success in gaining FDA approval for the commercial use
and distribution of Product R (the prior formulation of which was known as
"Reticulose"). All of our research and development efforts have been devoted to
the development of Product R.

         In order to commence clinical trials for regulatory approval of Product
R in the United States, we must submit an Investigational New Drug application
(IND) with the FDA. Filings with foreign regulatory agencies are required to
continue or begin new clinical trials outside the United States. We have
contracted with GloboMax LLC of Hanover, Maryland to assist us in our
preparation and filing of the IND with the FDA, and to otherwise assist us
through the FDA process with the objective of obtaining full approval for the
manufacture and commercial distribution of Product R in the United States. The
IND will seek approval to conduct a study testing the effectiveness of Product R
on human subjects with AIDS and other diseases. In the IND we intend to include,
among other things:

         o        information on chemistry, laboratory and animal controls;

         o        safety information for the initial study proposed to be
                  conducted on humans; and

         o        information assuring the identification, quality and purity of
                  Product R and a description of the physical, chemical and
                  microbiological characteristics of Product R.

         We believe that the IND will demonstrate the low rate of adverse
reactions occurring in the use of Product R as a treatment of AIDS and other
diseases, however, it is impossible to determine if or how much of the data from
any ongoing studies will be considered useful by the FDA in considering the IND
application, if it is ever filed. FDA approval to begin human clinical trials of
Product R pursuant to an approved IND will require significant cash
expenditures. Furthermore, Product R may never be approved for commercial
distribution by any country.

         We plan to continue to provide funding for testing programs in our
laboratory and at selected universities, medical schools, laboratories and
hospitals, but the amount of research that will be conducted at those
institutions will depend upon our financial status. Because our research and
development expenses and clinical trial expenses will be charged against
earnings for financial reporting purposes, we expect that losses from operations
will continue to be incurred for the foreseeable future.

RESULTS OF OPERATIONS

         YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997

         During the years ended December 31, 1999 and 1998, we incurred losses
of approximately $6,174,000 and $4,558,000, respectively, compared to
approximately $4,142,000 in 1997. Our increased losses for the fiscal years
ended December 31, 1999 and 1998 as compared with the fiscal year ended December
31, 1997 were attributable primarily to:

                  GENERAL AND ADMINISTRATIVE EXPENSES. General and
administrative expenses were approximately $1,681,000, $1,420,000 and $2,244,000
in 1997, 1998 and 1999, respectively. The decrease in general and administrative
expense from 1997 to 1998 resulted from the amortization of deferred
compensation costs associated with options granted to non-employees and recorded
as compensation expense in 1997 ($340,000), and also from the fact that 50% of
Dr. Hirschman's salary ($162,500) was accounted for as research and development
expense in 1998. The increase in general and administrative expense from 1998 to
1999 resulted from increased consulting fees (approximately $124,000 in 1998 to
$345,000 in 1999) primarily resulting from the GloboMax agreement, increased
health insurance costs (approximately $80,000 in 1998 to $160,000 in 1999),
increased professional fees (approximately $335,000 in 1998 and $425,000 in
1999) primarily for expenses relating to SEC registrations for convertible
debentures and warrants issued by Advanced Viral during 1998 and 1999, and
increased compensation expense related to modification of existing options
outstanding and payroll expenses ($450,000 in 1998 and $788,000 in 1999)
primarily due to the salaries of our President and Chief Financial Officer and
accounted for compensation expense.

                  RESEARCH AND DEVELOPMENT EXPENSE. Research and development
expense increased from approximately $818,000 in 1997, to $1,659,000 in 1998, to
approximately $1,746,000 in 1999. The increase from 1997 to 1998 resulted
primarily from the maintenance of the Yonkers, New York laboratory. The
approximate costs of rent, personnel, operating costs and laboratory supplies
associated with the Yonkers laboratory for the years ended 1997, 1998 and 1999
were charged to research and development expense as follows: $60,000, $950,000
and $1,325,000.

                  DEPRECIATION EXPENSE. Depreciation expense increased from
approximately $26,000 in 1997, $110,000 in 1998 to $231,000 in 1999 as a result
of the acquisition of furniture, fixtures and equipment for the Yonkers office
and laboratory, along with the additional leasehold improvements for laboratory
space leased during 1998 and 1999.

                  INTEREST EXPENSE. Interest expense for the years ended 1997,
1998 and 1999 was approximately $1,738,000, $1,471,000 and $2,007,000,
respectively. Included in interest expense for these periods was:


         o        the beneficial conversion feature on certain convertible
                  debentures of approximately $1,553,000, $836,000 and
                  $1,045,000 for the years ended 1997, 1998 and 1999,
                  respectively;

         o        interest expense associated with certain convertible
                  debentures of approximately $29,000, $95,000 and $163,000 for
                  the years ended 1997, 1998 and 1999, respectively;

         o        amortization of discount on certain warrants of approximately
                  $291,000 and $148,000 for the years ended 1998 and 1999,
                  respectively;

                                       14
<PAGE>   18

         o        amortization of loan costs of approximately $112,000, $230,000
                  and $331,000 for the years ended 1997, 1998 and 1999,
                  respectively; and

         o        additional financing costs related to effective date of
                  certain registration statements of $286,000 in 1999.

                  REVENUES. There were $10,953 and $656 in sales revenue in 1999
and 1998, respectively, compared to $2,278 in sales revenues for 1997. All sales
revenue resulted from distributors purchasing Product R for testing purposes.
The decrease in sales revenue from 1997 is due to the fact that in 1997, we sold
ampules of Product R outside the United States to independent organizations
solely for testing purposes. In 1998, the majority of the research and
development was conducted by our laboratory personnel, accordingly, sales to
outside entities for testing purposes were nominal. Interest income was
approximately $43,000 and $102,000 in 1999 and 1998, respectively, compared to
approximately $112,000 in 1997.

         THREE AND SIX MONTHS ENDED JUNE 30, 2000 AND 1999

         For the three and six month periods ended June 30, 2000, we incurred
losses of approximately $1,336,000 and $3,391,000, respectively, vs.
approximately $1,176,000 and $2,086,000 for the three and six month periods
ended June 30, 1999. Our increased losses were attributable primarily to:

              GENERAL AND ADMINISTRATIVE EXPENSE. Our increased losses during
the three and six months ended June 30, 2000 are principally due to increased
general and administrative expense (approximately $610,000 and $1,366,000 for
the three and six months ended June 30, 2000 vs. $499,000 and $937,000 for the
three and six months ended June 30, 1999, respectively). Included in the general
and administrative expenses are:

         o        an increase in consulting and professional fees (approximately
                  $142,000 and $469,000 for the three and six months ended June
                  30, 2000 vs. $126,000 and $271,000 for the three and six
                  months ended June 30, 1999, respectively) primarily
                  attributable to the engagement of an investor relations firm
                  and a consulting agreement with Harbor View Group;

         o        an increase in payroll and related expenses (approximately
                  $252,000 and $488,000 for the three and six months ended June
                  30, 2000 vs. $161,000 and $333,000 for the three and six
                  months ended June 30, 1999, respectively) attributable to
                  increased employee and officer salaries and the addition of a
                  Chief Financial Officer position.

              DEPRECIATION EXPENSE. Our increased losses during the three and
six months ended June 30, 2000 are also due to increased depreciation expense
(approximately $76,000 and $144,000 for the three and six months ended June 30,
2000 vs. $59,000 and $96,000 for the three months ended June 30, 1999,
respectively) due to the purchase of additional machinery and equipment and
leasehold improvements.

              INTEREST INCOME (EXPENSE). Our increased losses during the three
and six months ended June 30, 2000 are also due to increases and decreases in
interest expense (approximately $113,000 and $678,000 for the three and six
months ended June 30, 2000 vs. $217,000 and $312,000 for the three and six
months ended June 30, 1999, respectively). Interest income for the three and six
months ended June 30, 2000 was approximately $50,000 and $75,000 vs. $6,000 and
$21,000 for the three and six months ended June 30, 1999, respectively. Included
in the interest expense are:

                                       15
<PAGE>   19

         o        amortization of loan costs and other interest expense (as
                  reduced by other items previously accrued at year end) of
                  approximately $8,000 and $65,000 for the three and six months
                  ended June 30, 2000 vs. $60,000 and $118,000 for the three and
                  six months ended June 30, 1999, respectively;

         o        beneficial conversion feature on certain convertible
                  debentures of approximately $387,000 for the six months ended
                  June 30, 2000;

         o        amortization of discount on certain warrants of approximately
                  $106,000 and $226,000 for the three and six months ended June
                  30, 2000 vs. $36,000 and $73,000 for the three and six months
                  ended June 30, 1999, respectively;

         o        additional financing costs related to the effective date of
                  certain registration statements of $120,000 for the six months
                  ended June 30, 1999.

              RESEARCH AND DEVELOPMENT EXPENSE. Our increased losses during the
three months ended June 30, 2000 are also due to increased research and
development expenses (approximately $588,000 and $1,283,000 for the three and
six months ended June 30, 2000 vs. $409,000 and $767,000 for the three and six
months ended June 30, 1999, respectively). Included in the research and
development expenses are:

         o        consulting expenses payable to GloboMax LLC, a firm assisting
                  us with the preparation and filing of the IND, of
                  approximately $106,000 and $374,000 for the three and six
                  months ended June 30, 2000 vs. $110,000 for the three and six
                  months ended June 30, 1999;

         o        expenditures in connection with the drug approval process in
                  Argentina of approximately $71,000 and $116,000 for the three
                  and six months ended June 30, 2000 vs. $48,000 for the three
                  and six months ended June 30, 1999, respectively; and

         o        additional expenditures for payroll and related costs and
                  occupancy expenses for the New York facility (approximately
                  $286,000 and $597,000 for the three and six months ended June
                  30, 2000 vs. $231,000 and $444,000 for the three and six
                  months ended June 30, 1999, respectively).

              REVENUES. We had sales of approximately $2,000 and $5,000 for the
three and six months ended June 30, 2000 vs. $2,000 and $5,000 for the three and
six months ended June 30, 1999, respectively. All sales during these periods
were to distributors purchasing Product R for testing purposes.

LIQUIDITY

         YEARS ENDED DECEMBER 31, 1999 AND 1998

         As of December 31, 1999, we had current assets of approximately
$916,000, compared to approximately $1,795,000 at December 31, 1998. We had
total assets of approximately $2,862,000 and $3,305,000 at December 31, 1999 and
1998, respectively. The decrease in current and total assets was primarily
attributable to the use of investment capital to fund increased operating
expenditures.

         During 1999, we used cash of approximately $4,148,000 for operating
activities, as compared to approximately $3,365,000 in 1998. During 1999, we:

                                       16
<PAGE>   20

         o        incurred non-cash expenses of approximately $331,000 and
                  $148,000, respectively, relating to amortization of loan costs
                  and discount on warrants relating to convertible debentures
                  issued in 1997, 1998 and 1999;

         o        incurred non-cash expenses of approximately $1,045,000
                  relating to amortization of deferred interest associated with
                  the beneficial conversion feature of the 1998 and 1999
                  convertible debentures;

         o        expended approximately $770,000 in professional and consulting
                  fees;

         o        expended approximately $229,000 in laboratory supplies;

         o        expended approximately $1,685,000 for payroll and related
                  costs;

         During 1999, cash flows provided by investing and financing activities
was primarily due to the proceeds from the issuance of the 1998 and 1999
convertible debentures of approximately $3,000,000, and proceeds from the sale
of securities of approximately $700,000. In addition, we expended approximately
$407,000 for leasehold improvements and furniture and equipment at our Yonkers,
New York office.

         SIX MONTHS ENDED JUNE 30, 2000

         As of June 30, 2000, we had current assets of approximately $2,710,000,
compared to approximately $916,000 at December 31, 1999. We had total assets of
approximately $5,010,000 and $2,862,000 at June 30, 2000 and December 31, 1999,
respectively. The increase in current and total assets was primarily
attributable to proceeds received from the sale of securities and the exercise
of outstanding options (please refer to Statement of Stockholders Equity
contained in the Consolidated Condensed Financial Statements and the related
Notes to Consolidated Condensed Financial Statements included in this
prospectus.

         During the six months ended June 30, 2000, we used cash of
approximately $2,594,000 for operating activities, as compared to approximately
$1,727,000 for the six months ended June 30, 1999. During the six months ended
June 30, 2000, we:

         o        expended approximately $488,000 for payroll and related costs;

         o        incurred non-cash expenses of approximately $387,000 relating
                  to amortization of deferred interest associated with the
                  beneficial conversion feature of the second tranche of the
                  December 1999 convertible debentures;

         o        expended approximately $469,000 for professional and
                  consulting fees;

         o        incurred non-cash expenses relating to amortization of loan
                  costs and discount on warrants of approximately $106,000 and
                  $226,000, respectively, relating to convertible debentures
                  issued in 1998, 1999 and 2000; and

         o        incurred non-cash expenses of approximately $156,000 relating
                  to the issuance of warrants for consulting services.

         During the six months ended June 30, 2000, cash flows provided by
financing activities was primarily due to the proceeds from the sale of
convertible debentures, sale of common stock and exercise

                                       17
<PAGE>   21

of options in 1999 and 2000 of approximately $4,815,000. During the six months
ended June 30, 2000, cash flow used for investing activities were for
expenditures of approximately $473,000 for leasehold improvements and furniture
and equipment at our Yonkers, New York office.

         Under the terms of an agreement with RBB Bank, A.G. entered in November
1998 pursuant to which RBB purchased a 7% convertible debenture and related
warrants, we were required to file with the Commission a registration statement
to register shares of the common stock issuable upon conversion of the
convertible debenture and upon exercise of the related warrants to allow the
investors to resell such common stock to the public. Because the registration
statement was not declared effective by the Commission on or before April 13,
1999, the RBB agreement provides that we pay RBB a penalty equal to the sum of
(x) $30,000 and (y) $1,500 for each day lapsed after such date, until the
registration statement is declared effective by the Commission, provided,
however, that total penalties shall not exceed $100,000 in the aggregate. As of
the date hereof, RBB has not requested payment of the penalty, and we are
negotiating with RBB to have the penalty waived.

         Under the terms of an agreement with several purchasers entered in
December 1998, pursuant to which such purchasers purchased an aggregate of
4,917,276 shares of common stock and warrants to purchase an additional
2,366,788 shares of common stock, we were required to file with the Commission a
registration statement to register the common stock issued under the purchase
agreement, and upon exercise of the warrants to allow the resale of such common
stock to the public. Because the registration statement was not declared
effective by the Commission on or before May 21, 1999, the agreement provides
that we pay a penalty of $16,050 for each full calendar month or portion thereof
lapsed after such date, until the registration statement is declared effective,
provided, however, that total penalties shall not exceed $100,000 in the
aggregate. The registration statement was declared effective by the Commission
on December 16, 1999. Pursuant to an agreement in January 2000, the purchasers
in this transaction were paid an aggregate cash penalty of $96,300 in connection
with the registration statement.

         Under the terms of an agreement with several purchasers entered in June
1999, pursuant to which such purchasers purchased an aggregate of 1,851,852
shares of common stock and warrants to purchase an additional 926,528 shares of
common stock, we were required to file with the Commission a registration
statement to register the common stock issued under the purchase agreement, and
upon exercise of the warrants to allow the resale of such common stock to the
public. The agreement provides that if the registration statement is not
declared effective by the Commission prior to December 3, 1999, we must pay the
purchasers a penalty of $10,000, on a pro rata basis, for each full calendar
month lapsed after such date, and a pro rated amount of said $10,000 based on a
month of 30 or 31 days (as applicable to the month in which the registration
statement is declared effective), provided, however, that total penalties shall
not exceed $20,000 in the aggregate. The registration statement was declared
effective by the Commission on December 29, 1999.

         Under the terms of a securities purchase agreement with Focus Investors
LLC dated August 3, 1999 pursuant to which Focus Investors purchased 7%
convertible debentures and related warrants, we were required to file with the
Commission a registration statement to register shares of the common stock
issuable upon conversion of the debentures and upon exercise of the warrants to
allow the purchaser to resell such common stock to the public. The purchase
agreement provides that, if the registration statement is not declared effective
prior to December 1, 1999, or if the number of shares qualified for trading on
the OTC Bulletin Board or reserved for issuance is insufficient for issuance
upon the conversion of the debentures and the exercise of the warrants, or if a
blackout event occurs (as described in the agreement, each of these events
referred to as a "default"), we will be required to pay the purchaser a penalty
for each 30 day period during which a default shall be in effect equal to
$40,000, pro rated for the number of days during each period the defaults were
pending. To the extent the periodic amounts for all default periods

                                       18
<PAGE>   22

exceed $100,000 in the aggregate, the excess amount shall be paid in shares of
common stock, as set forth in the agreement. The agreement further provides that
until the registration statement has been filed and becomes effective, we will
not file any other registration statement without the written consent of Focus
Investors. The registration statement was declared effective by the Commission
on December 29, 1999.

         Under the terms of a securities purchase agreement with Endeavour
Capital Fund S.A. dated December 28, 1999 and related documents thereto pursuant
to which Endeavour purchased 7% convertible debentures and related warrants, we
were required to file with the Commission a registration statement to register
shares of the common stock issuable upon conversion of the debentures (together
with interest on the debentures, which is payable in common stock on conversion)
and upon and upon exercise of the warrants to allow the purchaser to resell such
common stock to the public. The purchase agreement provides that, if the
registration statement is not declared effective prior to April 1, 2000, or if
the purchaser is restricted from making sales of registrable securities covered
by a previously effective registration statement at any time after the effective
date other than during a permitted suspension period (as defined in the
agreement), then, we will be required to pay the purchaser $40,000 (2% of the
purchase price) for each 30-day period of such default (except that, prior to
the initial effectiveness of this registration statement, the amount will be
$30,000 (1.5% of the purchase price) during the first two 30-day periods of such
default). The registration statement was declared effective by the Commission on
January 18, 2000.

         In February 2000 pursuant to a securities purchase agreement, we sold
to Harbor View Group and various other purchasers 13,636,357 shares of common
stock, and warrants to purchase an aggregate of 5,454,544 shares of common stock
in a private offering transaction. Under the terms of the agreement, we were
required to use our best efforts to file a registration statement to register
the securities issued or issuable in connection with the agreement by May 31,
2000. The registration statement was filed with the Commission on May 26, 2000
and declared effective on June 7, 2000.


         On September 18, 2000 we entered into a private equity line of credit
agreement where we have the right to put shares of our common stock to an
investor from time to time to raise up to $20,000,000, subject to the conditions
and restrictions included in "Equity Line of Credit Agreement" described on
page 31 of this prospectus.


         The independent certified public accountants' report on our
consolidated financial statements for the fiscal year ended December 31, 1999,
includes an explanatory paragraph regarding our ability to continue as a going
concern. Note 2 to the Consolidated Financial Statements states that our ability
to continue operations is dependent upon the continued sale of our securities
for funds to meet our cash requirements, which raise substantial doubt about our
ability to continue as a going concern. Further, the accountant's report does
not include any adjustments that might result from the outcome of this
uncertainty. Although we may not be successful in doing so, we plan to eliminate
or remedy the deficiencies in our financial condition through the issuance of
additional securities for cash.

CAPITAL RESOURCES

         We have been dependent upon the proceeds from the continued sale of
securities for the funds required to continue operations at present levels and

         SECURITIES ISSUED IN 1997

         RBB BANK, A.G.: In February 1997 and October 1997, in order to finance
research and development, we sold $1,000,000 and $3,000,000, respectively,
principal amount of our ten-year 7% convertible debentures due February 28, 2007
and August 30, 2007, respectively, to RBB in offshore transactions pursuant to
Regulation S under the Securities Act. Accrued interest under the 1997
debentures was payable semiannually, computed at the rate of 7% per annum on the
unpaid principal balance from the date of issuance until the date of interest
payment. The 1997 debentures were convertible, at the option of the holder, into
shares of common stock pursuant to specified formulas. On April 22, 1997, June
6, 1997, July 3, 1997 and August 20, 1997, pursuant to notice by the holder,
RBB, to us under the February 1997 debenture, $330,000, $134,000, $270,000 and
$266,000, respectively, of the principal amount of the February 1997 debenture
was converted into 1,648,352, 894,526, 2,323,580 and 1,809,524 shares of the
common stock, respectively. As of August 20, 1997 the February 1997 debenture
was fully converted. On December 9, 1997, January 7, 1998, January 14, 1998,
February 19, 1998, February 23, 1998, March 31, 1998, May 4, 1998 and May 5,
1998, pursuant to notice by the holder, RBB, to us, $120,000, $133,000,
$341,250, $750,000, $335,750, $425,000, $275,000 and $620,000, respectively, of
the October 1997 debenture was converted into 772,201, 1,017,011, 2,512,887,
5,114,218, 1,498,884, 1,870,869, 1,491,485, and 3,299,979 shares of common
stock, respectively. As of May 5, 1998, the October 1997 debenture was fully
converted.

         In connection with the issuance of the 1997 debentures, we issued to
RBB six warrants to purchase common stock, three of which entitle the holder to
purchase, from February 21, 1997 through February 28, 2007, 178,378 shares of
the common stock, and three of which entitle the holder to purchase, from August
30, 1997 through August 30, 2007, 600,000 shares of the common stock. The
exercise prices of such warrants are $0.288, $0.576, $0.864, $0.20, $0.23 and
$0.27 per warrant share, respectively. Each such warrant provides that the
holder may elect to receive a reduced number of shares of common stock on the
basis of a cashless exercise; that number of shares bears the same proportion to
the total number shares

                                       20
<PAGE>   24


issuable under such warrant as the excess of the market value of shares of
common stock over the warrant exercise price bears to that market value. Each
warrant contains anti-dilution provisions which provide for the adjustment of
warrant price and warrant shares. As of the date of this prospectus, none of the
warrants have been exercised.

         SECURITIES ISSUED IN 1998

         RBB BANK, A.G.: In November 1998 we sold $1,500,000 principal amount of
our ten-year 7% convertible debenture due October 31, 2008 to RBB, as agent for
the accounts of certain persons, in an offshore transaction pursuant to
Regulation S under the Securities Act. Accrued interest under the convertible
debenture is payable semiannually, computed at the rate of 7% per annum on the
unpaid principal balance from the date of issuance until the date of interest
payment. The convertible debenture is convertible, at the option of the holder,
into shares of common stock pursuant to a specified formula. The actual number
of shares of common stock issued or issuable upon conversion of the convertible
debenture is subject to adjustment and could be materially less or more than the
above estimated amount, depending upon the future market price of the common
stock and the potential conversion of accrued interest into shares of common
stock.

         Based on the terms for conversion associated with the convertible
debenture, there is an intrinsic value associated with the beneficial conversion
feature of $625,000. Since conversion can occur immediately upon issuance of the
convertible debenture, this amount was recognized as interest expense in 1998.

         On January 19 and March 7, 2000, pursuant to notice by RBB, $1,122,500
and $377,500 principal amount of the November 1998 debenture was converted into
8,252,746 and 1,877,500 shares of common stock, respectively. As of March 7,
2000, the November 1998 debenture was fully converted.

         In connection with the issuance of the convertible debenture, we issued
to RBB two warrants to purchase common stock , each warrant entitling the holder
to purchase, until October 31, 2008, 375,000 shares of the common stock. The
exercise prices of the two warrants are $0.20 and $0.24 per warrant share,
respectively. Each warrant provides that the holder may elect to receive a
reduced number of shares of common stock on the basis of a cashless exercise;
that number of shares bears the same proportion to the total number shares
issuable under that warrant as the excess of the market value of shares of
common stock over the warrant exercise price bears to that market value. Each
warrant contains anti-dilution provisions which provide for the adjustment of
warrant price and warrant shares. As of the date of this prospectus, none of
these warrants had been exercised.

         The fair value of the warrants issued in connection with the
convertible debenture was estimated to be $48,000 ($0.064 per warrant) based
upon a financial analysis of the terms of such warrants using the Black-Scholes
pricing model with the following assumptions: expected volatility of 20%; a risk
free interest rate of 5.75% and an expected holding period of one year. This
amount has been amortized in the accompanying consolidated financial statements
as interest expense related to the convertible debenture.

         HARBOR VIEW GROUP, INC., ET AL.: In December 1998 pursuant to a
securities purchase agreement, we sold to Harbor View Group, Inc. and various
other purchasers 4,917,276 shares of common stock, and warrants to purchase an
aggregate of 2,366,788 shares of common stock, including (x) warrants to
purchase an aggregate of 1,966,788 shares of common stock and (y) a finder's fee
paid to Harbor View Group consisting of two warrants to purchase an aggregate
400,000 shares of common stock, in a private offering transaction pursuant to
Section 4(2) of the Securities Act, for an aggregate purchase price of

                                       21
<PAGE>   25

$802,500. Of the $802,500 purchase price, $600,000 was received on December 31,
1998, and $202,500 was received in January 1999. The warrants entitle the
holders to purchase an aggregate of 1,183,394 shares of common stock at an
exercise price of $0.2040 per share, and 1,183,394 shares at an exercise price
of $0.2448 per share. The warrants are exercisable at any time and from time to
time until December 31, 2003. Each warrant provides that the holder may elect to
receive a reduced number of shares of common stock on the basis of a cashless
exercise; that number of shares bears the same proportion to the total number
shares issuable under that warrant as the excess of the market value of shares
of common stock over the warrant exercise price bears to that market value. Each
warrant contains anti-dilution provisions which provide for the adjustment of
warrant price and warrant shares. As of the date of this prospectus, warrants to
purchase 294,118 shares of common stock had been exercised.

         The fair value of the warrants issued as of January 7, 1999, the date
of issuance of the shares in connection with the securities purchase agreement,
was estimated to be $494,000 ($0.0208 per warrant) based upon a financial
analysis of the terms of such warrants using the Black-Scholes Pricing Model
with the following assumptions: expected volatility of 20%, and a risk free
interest rate of 6% through the December 31, 2003 expiration date. This amount
is being amortized to interest expense in the accompanying consolidated
financial statements.

         SECURITIES ISSUED IN 1999

         BERMAN, ET AL.: In July 1999 pursuant to a securities purchase
agreement, we sold 1,851,852 shares of common stock, and warrants to purchase an
aggregate of 925,926 shares of common stock to Michael Berman, Pak-Lin Law and
Kwong Wai Au in a private offering transaction pursuant to Section 4(2) of the
Securities Act, for an aggregate purchase price of $500,000, received in July
1999. The warrants entitle the holders to purchase 463,264 and 463,264 shares of
common stock at exercise prices of $0.324 and $0.378 per share, respectively.
The warrants are exercisable at any time and from time to time until June 28,
2004. Each warrant provides that the holder may elect to receive a reduced
number of shares of common stock on the basis of a cashless exercise; that
number of shares bears the same proportion to the total number shares issuable
under that warrant as the excess of the market value of shares of common stock
over the warrant exercise price bears to that market value. Each warrant
contains anti-dilution provisions which provide for the adjustment of warrant
price and warrant shares. As of the date of this prospectus, none of the
warrants had been exercised.

         The fair value of the warrants issued as of July 9, 1999, the date of
issuance of the shares in connection with the securities purchase agreement, was
estimated to be $37,000 ($0.04 per warrant) based upon a financial analysis of
the terms of such warrants using the Black-Scholes Pricing Model with the
following assumptions: expected volatility of 20%, and a risk free interest rate
of 5.75% through the June 30, 2004 expiration date. This amount is being
amortized to interest expense in the accompanying consolidated financial
statements.

         FOCUS INVESTORS LLC: Pursuant to a securities purchase agreement dated
August 3,1999 in a private offering transaction under Section 4(2) of the
Securities Act, we sold to Focus Investors LLC an aggregate of 20 units for an
aggregate gross purchase price of $2 million, each unit consisting of $100,000
principal amount of our ten-year 7% convertible debentures due August 3, 2009,
and series W warrants to purchase 50,000 shares of our common stock exercisable
until August 3, 2004. Accrued interest under the convertible debentures is
payable semiannually, computed at the rate of 7% per annum on the unpaid
principal balance from the date of issuance until the date of interest payment.
The convertible debentures are convertible, at the option of the holder, into
shares of common stock pursuant to a specified formula. The actual number of
shares of common stock issued or issuable upon conversion of the convertible
debentures is subject to adjustment and could be materially less or more than
the above estimated amount,

                                       22
<PAGE>   26

depending upon the future market price of the common stock and the potential
conversion of accrued interest into shares of common stock. On January 19,
February 17, and March 3, 2000, pursuant to notice by Focus Investors, $300,000,
$900,000, and $800,000 principal amount of the Focus debentures was converted
into 2,178,155, 6,440,725 and 5,729,967 shares of common stock, respectively. As
of March 3, 2000, the debenture was fully converted.

         The exercise price of the series W warrants is $0.2461 per warrant
share. The warrants provide that the holder may elect to receive a reduced
number of shares of common stock on the basis of a cashless exercise; The series
W warrants contain anti-dilution provisions which provide for the adjustment of
the warrant price and warrant shares. As of March 17, 2000, all of the warrants
had been exercised.

         The fair value of the warrants issued as of August 3, 1999 in
connection with the securities purchase agreement was estimated to be $52,953
($0.0526 per warrant) based upon a financial analysis of the terms of such
warrants using the Black-Scholes Pricing Model with the following assumptions:
expected volatility of 20%, and a risk free interest rate of 5.75% through the
June 30, 2004 expiration date. This amount has been amortized to interest
expense in the accompanying consolidated financial statements.

         ENDEAVOUR CAPITAL FUND S.A.: Pursuant to a securities purchase
agreement dated December 28, 1999 in a private offering transaction under
Section 4(2) of the Securities Act, we issued the first $1,000,000 tranche of
$2,000,000 in aggregate principal amount of our 7% convertible debentures due
December 31, 2004 to Endeavour Capital Fund S.A. (the "Endeavour Transaction").
In connection with the sale of the first tranche of debentures, we issued
warrants to purchase 100,000 shares of our common stock to Endeavour, and two
warrants to purchase 5,000 shares of common stock to Endeavour's legal counsel.
Accrued interest under the convertible debentures is computed at the rate of 7%
per annum on the unpaid principal balance from the date of issuance until the
date of interest payment and is payable on conversion of the debenture or on
maturity in common stock using the same conversion formula. The convertible
debentures are convertible, at the option of the holder, into shares of common
stock pursuant to a specified formula. The actual number of shares of common
stock issued or issuable upon conversion of the convertible debentures is
subject to adjustment and could be materially less or more than the estimated
number of shares in this prospectus, depending upon the future market price of
the common stock and the potential conversion of accrued interest into shares of
common stock.

         These warrants expire on December 31, 2002 and are exercisable at
$0.19916667 per share. The warrants provide that the holder may elect to receive
a reduced number of shares of common stock on the basis of a cashless exercise.
The warrants contain anti-dilution provisions which provide for the adjustment
of the warrant price and warrant shares. As of the date of this prospectus, none
of these warrants had been exercised.

         The fair value of the warrants issued as of December 28, 1999 in
connection with the securities purchase agreement was estimated to be $4,285
($0.0429 per warrant) based upon a financial analysis of the terms of such
warrants using the Black-Scholes Pricing Model with the following assumptions:
expected volatility of 20%, and a risk free interest rate of 6% through the
December 31, 2002 expiration date. This amount has been amortized to interest
expense in the accompanying consolidated financial statements.

         SECURITIES ISSUED IN 2000

         ENDEAVOUR CAPITAL FUND S.A.: In January 2000, in connection with the
Endeavour Transaction, we issued the second $1,000,000 tranche of $2,000,000 in
aggregate principal amount of our 7% convertible

                                       23
<PAGE>   27

debentures due December 31, 2004, along with warrants to purchase 100,000 shares
of our common stock to Endeavour Capital Fund, S.A. The terms of the second
tranche of debentures and warrants are the identical to the terms of the
debentures and warrants issued in first tranche of the Endeavour Transaction.

         The fair value of the second tranche of warrants issued in January 2000
in connection with the securities purchase agreement was estimated to be $13,600
($0.0136 per warrant) based upon a financial analysis of the terms of such
warrants using the Black-Scholes Pricing Model with the following assumptions:
expected volatility of 90%, and a risk free interest rate of 6% through the
December 31, 2002 expiration date. This amount has been amortized to interest
expense in the accompanying consolidated financial statements.

         On January 27, February 22, 23, 24, and 29, and September 13, 2000
pursuant to notice by Endeavour Capital Fund, $150,000, $135,000, $715,000,
$785,000, $200,000 and $15,000 principal amount of the Endeavour debentures was
converted into 1,105,435, 988,913, 5,149,035, 5,622,696, 1,036,674 and 42,088
shares of common stock, respectively. As of September 13, 2000, the debenture
was fully converted.

         HARBOR VIEW GROUP, INC. On February 7, 2000 pursuant to a consulting
agreement with Harbor View Group, we issued to Harbor View warrants to purchase
1,750,000 shares at an exercise price of $0.21 per share, and warrants to
purchase 1,750,000 shares at an exercise price of $0.26 per share, until
February 28, 2005, in exchange for consulting services provided or to be
provided to us. Each warrant contains anti-dilution provisions which provide for
the adjustment of warrant price and warrant shares. As of the date of this
prospectus, none of these warrants had been exercised.

         The fair value of the warrants is estimated to be $200,249 ($.057 per
warrant) based upon a financial analysis of the terms of the warrant using the
Black-Scholes Pricing Model with the following assumptions: expected volatility
of 90%; a risk free interest rate of 6% and an expected holding period of eleven
months (the term of the consulting agreement). We have determined that $89,045
of the fair value relates to past services and, accordingly, we have expensed
this portion in the three months ended March 31, 2000. The remaining $111,204 is
included in other current assets and is being amortized over the remaining term
of the agreement.

         HARBOR VIEW GROUP, INC., ET AL. In February 2000 pursuant to a
securities purchase agreement, we sold to Harbor View Group and various other
purchasers 13,636,357 shares of common stock, and warrants to purchase an
aggregate of 5,454,544 shares of common stock in a private offering transaction
pursuant to Section 4(2) of the Securities Act, for an aggregate purchase price
of $3,000,000. Half of the warrants are exercisable at $0.275 per share, and
half of the warrants are exercisable at $0.33 per share, until February 28,
2005. Each warrant provides that the holder may elect to receive a reduced
number of shares of common stock on the basis of a cashless exercise; that
number of shares bears the same proportion to the total number shares issuable
under that warrant as the excess of the market value of shares of common stock
over the warrant exercise price bears to that market value. Each warrant
contains anti-dilution provisions which provide for the adjustment of warrant
price and warrant shares. As of the date of this prospectus, none of these
warrants had been exercised.

         The fair value of the warrants issued as of February 16, 2000 in
connection with the securities purchase agreement was estimated to be $1,582,734
($0.290 per warrant) based upon a financial analysis of the terms of such
warrants using the Black-Scholes Pricing Model with the following assumptions:
expected volatility of 90%, and a risk free interest rate of 6% through the
February 28, 2005 expiration date. This amount is being amortized to interest
expense in the accompanying consolidated financial statements.

PROJECTED EXPENSES

         During the next 12 months, we expect to spend approximately
$10,000,000, on research and development related activities, including
approximately:

         o        $4,000,000 for operating expenses;

         o        $4,000,000 for the IND's for Product R to the FDA in
                  connection with GloboMax's project management services for the
                  pre-clinical development and IND submissions of Product R to
                  the FDA, the development of standard operating procedures and
                  validation protocol for the preparation and manufacture of
                  Product R, and toxicology studies of Product R;

         o        $1,000,000 for capital expenditures for leasehold improvements
                  and equipment at our Yonkers, New York office relating to
                  additional laboratories and manufacturing and production
                  facilities for Product R; and

         o        $1,000,000 for additional personnel.

         We anticipate that we can continue operations through October 2000 with
our current liquid assets, including the proceeds from the recent sale of the
convertible debenture and other securities if no stock options or warrants are
exercised nor additional securities sold. If all of the outstanding stock
options and warrants are exercised, we will receive net proceeds of
approximately $16.0 million. Those proceeds will contribute to general and
administrative and working capital and will permit us to substantially increase
our budget for research and development and clinical trials and testing and to
operate at significantly increased levels of operation, assuming Product R
receives approvals and prospects for sales increase to justify such increased
levels of operation. The recent prevailing market price for shares of common
stock has from time to time been above the exercise prices of certain of the
outstanding options and warrants. As such, recent trading levels may not be
sustained nor may any additional options or warrants be exercised. If less than
60% or none of the outstanding options and warrants are exercised, and we obtain
no other additional financing, in order for us to achieve the level of
operations contemplated by management, management anticipates that we will have
to limit intentions to expand operations beyond current levels.

         We anticipate that we will be required to sell additional securities to
obtain the funds necessary to further our research and development activities.
We are currently seeking debt financing, licensing agreements, joint ventures
and other sources of financing, but the likelihood of obtaining such financing
on favorable terms is uncertain. Management anticipates that they will have to
defer their salaries if financing is not available in order to continue
operations,. Management does not believe that, at present, debt or equity
financing will be readily obtainable on favorable terms unless and until FDA
approval for phase I clinical testing is granted. Because of the large
uncertainties involved in the FDA approval process for commercial drug use on
humans, it is possible that we may never be able to sell Product R commercially.

                                    BUSINESS

OVERVIEW

         Advanced Viral Research Corp. was formed in July 1985 to engage in the
production and marketing, promotion and sale of a pharmaceutical drug with the
trade name RETICULOSE(TM). Under the

                                       25
<PAGE>   29

Federal Food, Drug, and Cosmetic Act, as amended in 1962, the Food and Drug
Administration, or FDA, classified Reticulose as a "new drug" requiring FDA
approval prior to any sale in the United States. Reticulose (the current
formulation of which is now known as and hereinafter referred to as PRODUCT
R(TM) ) has not been approved for sale or use by the FDA or any foreign
government body, and thus we have not as yet commenced any commercial
operations. We are dependent on registration and/or approval by applicable
regulatory authorities of Product R in order to commence commercial operations.

         Our operations over the last five years have been limited principally
to engaging in research, IN VITRO testing and analysis of Product R in the
United States, and engaging others to perform testing and analysis of Product R
on human patients overseas. The FDA has not approved human clinical trials for
Product R in the United States. We may be required, in the absence of grants or
other subsidies, to bear the expenses of the first phase of human clinical
trials to the extent the FDA permits human clinical trials to occur. We do not
know what the actual cost of such trials would be. If we need additional
financing to fund such human clinical trials, it may not be available to us,
which may force us to reduce our operations.

GOVERNMENT REGULATION

         The FDA imposes substantial requirements upon and conditions precedent
to the introduction of therapeutic drug products, such as Product R, through
lengthy and detailed laboratory and clinical testing procedures, sampling
activities and other costly and time consuming procedures to demonstrate that
such products are both safe and effective in treating the indications for which
approval is sought. After testing in animals, an Investigational New Drug, or
IND, application must be filed with the FDA to obtain authorization for human
testing. When the clinical testing has been completed and analyzed, final
manufacturing processes and procedures are in place, and certain other required
information is available to the manufacturer, a manufacturer may submit a new
drug application, or NDA, to the FDA. No action can be taken to market Product
R, or any therapeutic drug product, in the United States until an NDA has been
approved by the FDA.

         The IND process in the United States is governed by regulations
established by the FDA which strictly control the use and distribution of
investigational drugs in the United States. The guidelines require that an
application contain sufficient information to justify administering the drug to
humans, that the application include relevant information on the chemistry,
pharmacology and toxicology of the drug derived from chemical, laboratory and
animal or IN VITRO testing, and that a protocol be provided for the initial
study of the new drug to be conducted on humans.

         In order to conduct a clinical trial of a new drug in humans, a sponsor
must prepare and submit to the FDA a comprehensive IND. The focal point of the
IND is a description of the overall plan for investigating the drug product and
a comprehensive protocol for each planned study. The plan is carried out in
three phases: phase I clinical trials, which involve the administration of the
drug to a small number of healthy subjects to determine safety, tolerance,
absorption and metabolism characteristics; phase II clinical trials, which
involve the administration of the drug to a limited number of patients for a
specific disease to determine dose response, efficacy and safety; and phase III
clinical trials, which involve the study of the drug to gain confirmatory
evidence of efficacy and safety from a wide base of investigators and patients.

         An investigator's brochure must be included in the IND and the IND must
commit the sponsor to obtain initial and continual review and approval of the
clinical investigation. A section describing the composition, manufacture and
control of the drug substance and the drug product is included in the IND.
Sufficient information is required to be submitted to assure the proper
identification, quality, purity and

                                       26
<PAGE>   30

strength of the investigational drug. A description of the drug substance,
including its physical, chemical, and biological characteristics, must also be
included in the IND. The general method of preparation of the drug substance
must be included. A list of all components including inactive ingredients must
also be submitted. There must be adequate information about pharmacological and
toxicological studies of the drug involving laboratory animals or IN VITRO tests
on the basis of which the sponsor has concluded that it is reasonably safe to
conduct the proposed clinical investigation. Where there has been widespread use
of the drug outside of the United States or otherwise, it is possible in some
limited circumstances to use well documented clinical experience as a substitute
for other pre-clinical work.

         After the FDA approves the IND, the investigation is permitted to
proceed, during which the sponsor must keep the FDA informed of new studies,
including animal studies, make progress reports on the study or studies covered
by the IND, and also be responsible for alerting FDA and clinical investigators
immediately of unforeseen serious side effects or injuries.

         When all clinical testing has been completed and analyzed, final
manufacturing processes and procedures are in place, and certain other required
information is available to the manufacturer, a manufacturer may submit an NDA
to the FDA. An NDA must be approved by the FDA covering the drug before its
manufacturer can commence commercial distribution of the drug. The NDA contains
a section describing the clinical investigations of the drug which section
includes, among other things, the following: a description and analysis of each
clinical pharmacology study of the drug; a description and analysis of each
controlled clinical study pertinent to a proposed use of the drug; a description
of each uncontrolled clinical study including a summary of the results and a
brief statement explaining why the study is classified as uncontrolled; and a
description and analysis of any other data or information relevant to an
evaluation of the safety and effectiveness of the drug product obtained or
otherwise received by the applicant from any source foreign or domestic. The NDA
also includes an integrated summary of all available information about the
safety of the drug product including pertinent animal and other laboratory data,
demonstrated or potential adverse effects of the drug, including clinically
significant potential adverse effects of administration of the drug
contemporaneously with the administration of other drugs and other related
drugs. A section is included describing the statistical controlled clinical
study and the documentation and supporting statistical analysis used in
evaluating the controlled clinical studies.

         Another section of the NDA describes the data concerning the action of
a drug in the human body over a period of time and data concerning the extent of
drug absorption in the human body or information supporting a waiver of the
submission of such data. Also included in the NDA is a section describing the
composition, manufacture and specification of the drug substance including the
following: a full description of the drug substance, its physical and chemical
characteristics; its stability; the process controls used during manufacture and
packaging; and such specifications and analytical methods as are necessary to
assure the identity, strength, quality and purity of the drug substance as well
as the availability of the drug products made from the substance. NDA's contain
lists of all components used in the manufacture of the drug product and a
statement of the specifications and analytical methods for each component. Also
included are studies of the toxicological actions of the drug as they relate to
the drug's intended uses.

         The data in the NDA must establish that the drug has been shown to be
safe for use under its proposed labeling conditions and that there is
substantial evidence that the drug is effective for its proposed use(s).
Substantial evidence is defined by statute and FDA regulation to mean evidence
consisting of adequate and well-controlled investigations, including clinical
investigations by experts qualified by scientific training and experience, to
evaluate the effectiveness of the drug involved.

                                       27
<PAGE>   31

         On September 20, 1984, Bernard Friedland, our former President and
current Chairman of the Board, as sponsor, submitted to the FDA an IND to
conduct a study testing the effectiveness of Product R on human subjects with
AIDS, as well as certain other viruses. The FDA has issued four letters of
deficiency with regard to the IND. In a letter dated November 29, 1984, the FDA
indicated, among other deficiencies noted, that the publications submitted with
the IND and relating to the effectiveness of Product R on virus related diseases
will not be accepted in support of the safety of Product R unless we could
establish that the proposed formulation of Product R is the same as the
formulation of Product R referenced in those publications. In addition, the FDA
required, among other things, that an IND application include relevant
information on the chemistry, laboratory and animal controls to assure the
integrity of the dosage form and that safety information be provided for the
initial study proposed to be conducted on humans. The FDA also required that the
information assure the proper identification, quality, purity and strength of
Product R and a description of the physical, chemical and microbiological
characteristics of Product R. On September 11, 1987, we received a further
deficiency letter from the FDA, stating that no data had been submitted
supporting IN VITRO anti-HIV activity or any criterion for a biological response
modifier.

         On March 6, 1992, we submitted an amendment to the IND which attempted
to address the FDA's concerns. In response to the March 1992 submission, we
received a third deficiency letter from the FDA dated July 27, 1992, which
provided detailed comments with respect to chemistry, toxicology, microbiology
and clinical areas requiring further studies and action on our part. In June
1995, we received further correspondence from the FDA which stated, among other
things, that our prior submissions to the FDA did not provide an adequate
response to the FDA's earlier request for preclinical information and
accordingly our IND was "inactivated."

         We have not formally responded to the 1992 deficiency letters or the
1995 deficiency letter, nor have any of the studies cited in those letters been
undertaken. In February 1998, we contracted with GloboMax LLC of Hanover,
Maryland to advise and assist us in our preparation of a new IND to be filed
with the FDA, and to otherwise guide us through the FDA process with the
objective of obtaining full approval for Product R in the United States. During
the year ended December 31, 1999, GloboMax continued its project management
services for the pre-clinical development and IND submission of Product R to the
FDA, the development of standard operating procedures and validation protocol
for the preparation and manufacture of Product R. Expenses paid during 1999
relating to the GloboMax agreement were approximately $200,000. Pursuant to the
agreement with GloboMax, we are obligated to pay for services on an hourly
basis, at prescribed rates.

         We currently do not have the resources necessary to complete the FDA
approval process. We may allocate certain proceeds from the exercise of
currently outstanding options and warrants for the purpose of filing a new IND
with the FDA, however, such proceeds, if any, will not be sufficient to improve
our financial condition to any great degree. It is possible that the new IND for
clinical tests of Product R on humans, if submitted, will not be approved by the
FDA for human clinical trials on AIDS or other diseases, and that any tests
previously conducted or to be conducted will not satisfy FDA requirements. It is
also possible that the results of such human clinical trials, if performed, will
not prove that Product R is safe or effective in the treatment of AIDS or other
diseases, or that the FDA will not approve the sale of Product R in the United
States if we submitted a proper NDA. It is not known at this time how extensive
the phase II and phase III clinical trials will be, if they are conducted. The
data generated may not show that the drug Product R is safe and effective, and
even if the data shows that Product R is safe and effective, obtaining approval
of the NDA could take years and require financing of amounts not presently
available to us.

                                       28
<PAGE>   32

         In connection with our activities outside the United States, we are
also subject to regulatory requirements governing the testing, approval,
manufacture, labeling, marketing and sale of pharmaceutical and diagnostic
products, which requirements vary from country to country. Government regulation
in certain countries may delay marketing of Product R for a considerable period
of time and impose costly procedures upon our activities. The extent of
potentially adverse government regulations which might arise from future
legislation or administrative action cannot be predicted. Whether or not FDA
approval has been obtained for a product, approval of the product by comparable
regulatory authorities of foreign countries must be obtained prior to marketing
the product in those countries. The approval process may be more or less
rigorous from country to country, and the time required for approval may be
longer or shorter than that required in the United States. Clinical studies
conducted outside of any country may not be accepted by such country, and the
approval of any pharmaceutical or diagnostic product in one country does not
assure that such product will be approved in another country. Accordingly, until
registration is granted, if ever, in the United States or another developed or
developing country, we do not expect that we will be able to generate material
sales revenue. We received a grant of authority from the Bahamian Port
Authority, an authorized division of the Bahamian Government, on October 15,
1992 confirming the right of our subsidiary, Advance Viral Research, Ltd., a
Bahamian corporation, to carry on the manufacture and export sale of ethical
pharmaceutical products. See "--Marketing And Sales."

RESEARCH, DEVELOPMENT AND TESTING

         For the period from inception (February 20, 1984) through June 30, 2000
we expended approximately $6.6 million on testing and research and development
activities either in our laboratories or pursuant to various testing agreements
with both domestic and foreign companies. In 1995, we retained Shalom Hirschman
as our President. As President, Dr. Hirschman established our research facility
in Yonkers, New York, monitored the testing of Product R and recently performed
analyses of Product R with our scientific personnel, which analyses we believe
may be used in connection with the FDA approval process. We currently are
funding research and testing to:

         o        determine the safety of the topical use of Product R on
                  animals and cultured human cells;

         o        assess the effectiveness of the topical application of Product
                  R on HPV and certain cancer causing proteins of HPV. Recent
                  laboratory testing has indicated that Product R may inhibit
                  the expression of a protein of HPV which causes cervical
                  cancer;

         o        study the effects of Product R in inhibiting the mutation of
                  the AIDS virus in humans;

         o        assess the effectiveness of the topical application of Product
                  R for the treatment of persons diagnosed with herpes
                  labialis/genital infections;

         o        compare the results of treatment of persons diagnosed with
                  AIDS taking a three drug cocktail and Product R with those
                  taking a three drug cocktail and a placebo;

         o        determine the effectiveness of Product R for the treatment of
                  rheumatoid arthritis in humans;

         o        study the effects of Product R in inhibiting the production of
                  a key cancer-causing protein (E-7 protein) of the human
                  papilloma virus (HPV). The E-7 protein is associated with the
                  development of cervical cancer in women infected with cancer
                  causing subtypes of HPV; and

                                       29
<PAGE>   33

         o        study the effects of Product R in inhibiting the production of
                  key cellular receptors for HIV (CCR5 and CXCR4 receptors). The
                  CCR5 and CXCR4 receptors are two of the cell receptors used by
                  the AIDS virus, HIV, to attach to its target cell and initiate
                  infection.

         Our studies detailing the results of the above research and testing may
not positively impact the FDA's decision to approve a new IND for Product R or
approve the marketing, sales or distribution of Product R within the United
States, and as a result may not improve our chances of gaining approval for the
marketing, sales or distribution of Product R anywhere in the world.

PATENTS

         We believe that patent protection and trade secret protection are
important to our business and that our future will depend, in part, on our
ability to maintain trade secret protection, obtain patents and operate without
infringing the proprietary rights of others both in the United States and
abroad. We have currently pending 15 patent applications with the United States
Patent and Trademark Office (the "PTO") relating to Product R and 17 foreign
patent applications. In the United States, we have one patent allowed and three
have been issued by the PTO. As patent applications in the United States are
maintained in secrecy until patents issue and as publication of discoveries in
the scientific or patent literature often lag behind the actual discoveries, we
cannot be certain that we were the first to make the inventions covered by each
of our pending patent applications or that we were the first to file patent
applications for such inventions. Furthermore, the patent positions of
biotechnology and pharmaceutical companies are highly uncertain and involve
complex legal and factual questions, and, therefore, the breadth of claims
allowed in biotechnology and pharmaceutical patents or their enforceability
cannot be predicted. We cannot be sure that any additional patents will issue
from any of our patent applications or, should any patents issue, that we will
be provided with adequate protection against potentially competitive products.
Furthermore, we cannot be sure that should patents issue, they will be of
commercial value to us, or that private parties, including competitors, will not
successfully challenge our patents or circumvent our patent position in the
United States or abroad. See "Business - Legal Proceedings."

         In the absence of adequate patent protection, our business may be
adversely affected by competitors who develop comparable technology or products.
Moreover, pursuant to the terms of the Uruguay Round Agreements Act, patents
filed on or after June 8, 1995 have a term of twenty years from the date of such
filing, irrespective of the period of time it may take for such patent to
ultimately issue. This may shorten the period of patent protection afforded to
our products as patent applications in the biopharmaceutical sector often take
considerable time to issue. Under the Drug Price Competition and Patent Term
Restoration Act of 1984 (the "Patent Act"), a sponsor may obtain marketing
exclusivity for a period of time following FDA approval of certain drug
applications, regardless of patent status, if the drug is a new chemical entity
or if new clinical studies were used to support the marketing application for
the drug. Pursuant to the FDA Modernization Act of 1997, the period of
exclusivity can be extended if the applicant performs certain studies in
pediatric patients. This marketing exclusivity prevents a third party from
obtaining FDA approval for a similar or identical drug under an Abbreviated New
Drug Application ("ANDA") or a "505(b)(2)" New Drug Application. The statute
also allows a patent owner to obtain an extension of applicable patent terms for
a period equal to one-half the period of time elapsed between the filing of an
IND and the filing of the corresponding NDA plus the period of time between the
filing of the NDA and FDA approval, with a five year maximum patent extension.
We cannot be sure that we will be able to take advantage of either the patent
term extension or marketing exclusivity provisions of this law.

         In order to protect the confidentiality of our technology, including
trade secrets and know-how and other proprietary technical and business
information, we require all of our employees, consultants, advisors and
collaborators to enter into confidentiality agreements that prohibit the use or
disclosure of

                                       30
<PAGE>   34

information that is deemed confidential. The agreements also oblige our
employees, consultants, advisors and collaborators to assign to us developments,
discoveries and inventions made by such persons in connection with their work
with us. We cannot be sure that confidentiality will be maintained or disclosure
prevented by these agreements or that our proprietary information or
intellectual property will be protected thereby or that others will not
independently develop substantially equivalent proprietary information or
intellectual property.

         The pharmaceutical industry is highly competitive and patents have been
applied for by, and issued to, other parties relating to products competitive
with Product R. Therefore, Product R and any other drug candidates may give rise
to claims that they infringe the patents or proprietary rights of other parties
existing now and in the future. Furthermore, to the extent that we or our
consultants or research collaborators use intellectual property owned by others
in work performed for us, disputes may also arise as to the rights in such
intellectual property or in related or resulting know-how and inventions. An
adverse claim could subject us to significant liabilities to such other parties
and/or require disputed rights to be licensed from such other parties. We cannot
be sure that any license required under any such patents or proprietary rights
would be made available on terms acceptable to us, if at all. If we do not
obtain such licenses, we may encounter delays in product market introductions,
or may find that the development, manufacture or sale of products requiring such
licenses may be precluded. In addition, we could incur substantial costs in
defending ourselves in legal proceedings instituted before the PTO or in a suit
brought against it by a private party based on such patents or proprietary
rights, or in suits by us asserting our patent or proprietary rights against
another party, even if the outcome is not adverse to us. There are extensions
available under the Patent Act if the delay in prosecution of the patent
application results from a delay in the PTO's handling of any interference or
appeal involving the application. We have not conducted any searches or made any
independent investigations of the existence of any patents or proprietary rights
of other parties.


EQUITY LINE OF CREDIT AGREEMENT

         On September 18, 2000, we signed a private equity line of credit
agreement with Spinneret Financial Systems, Inc. Pursuant to this equity line of
credit agreement and subject to the satisfaction of certain conditions, Advanced
Viral may sell and issue to Spinneret, from time to time, up to an aggregate of
$20,000,000 of our common stock. Beginning on the date that a registration
statement covering the resale of the shares issuable pursuant to the equity line
of credit is declared effective by the Commission, and continuing for thirty
(30) months thereafter, we may, from time to time, in our sole discretion, sell
or "put" shares of our common stock to Spinneret Financial Systems at a price
equal to the market price of the common stock. Under the equity line of credit
agreement, the market price of Advanced Viral common stock, for purposes of
determining the purchase price, is the average of the six lowest closing bid
prices, as reported by Bloomberg, L.P., of our common stock for the 25 trading
day period ending on the date we notify Spinneret of our intention to put common
stock to it, or, in other words, request an advance.

         The maximum advance amount on any advance notice date is equal to the
difference between (i) the amount indicated in the Maximum Advance Amount column
opposite the range of the 25 Day Average Daily Volume Traded on such advance
notice date, as set forth in the table below and (ii) the sum of the advances
made pursuant to the agreement, in the 15 trading days immediately preceding the
advance notice date:

                  $1,000,000 plus                                $2,000,000


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

(1) The 25-Day Average Volume Traded is equal to the bid price multiplied by the
    volume for each of the 25 trading days preceding the advance notice date.

         Our ability to put shares of common stock to Spinneret Financial
Systems is subject to certain conditions and limitations, including, but not
limited to, the following:

                  o        the registration statement covering the resale of the
                           shares must have previously become effective and
                           shall remain effective and available for making
                           resales of the put shares;

                  o        our representations and warranties to Spinneret
                           Financial Systems contained in the equity line of
                           credit agreement must be accurate as of the date of
                           each put;

                  o        no statute, rule, regulation, executive order,
                           decree, ruling, or injunction may be in effect which
                           prohibits or directly and adversely affects any of
                           the transactions contemplated by the equity line of
                           credit agreement;

                  o        at the time of an advance, there must not have been
                           any material adverse change in our business,
                           operations, properties, prospects, or financial
                           condition since the date of filing of our most recent
                           report with the SEC;

                  o        our common stock must not have been delisted from the
                           Bulletin Board or suspended from trading by the SEC
                           or the Bulletin Board; and

                  o        at least fifteen (15) trading days must have elapsed
                           since the last date Advanced Viral put shares to
                           Spinneret Financial Systems.

         We cannot assure you that we will satisfy all of the conditions
required under the equity line of credit agreement or that Spinneret Financial
Systems will have the ability to purchase all or any of the shares of common
stock put to it thereunder.

         Under the equity line of credit agreement, we agreed to register the
common stock for resale by Spinneret Financial Systems, which will permit
Spinneret Financial Systems to resell the common stock from time to time in the
open market or in privately-negotiated transactions. We will prepare the
registration statement and file amendments and supplements thereto as may be
necessary in order to keep it effective as long as the equity line of credit
agreement remains in effect or Spinneret Financial Systems owns any of our
common stock. We have agreed to bear certain expenses, other than broker
discounts and commissions, if any, in connection with the preparation and filing
of the registration statement and any amendments to it.

         In addition, pursuant to the equity line of credit agreement, each
officer, director and affiliate of Advanced Viral has agreed that he, she or it
will not, directly or indirectly, without the prior written consent of
Spinneret, issue, offer, agree or offer to sell, sell, grant an option for the
purchase or sale of, transfer, pledge, assign, hypothecate, distribute or
otherwise encumber or dispose of (whether pursuant to Rule 144 promulgated under
the Securities Act of 1933, as amended, or otherwise) any shares of common
stock, including options, rights, warrants or other securities underlying,
convertible into, exchangeable or exercisable for or evidencing any right to
purchase or subscribe for any common stock (whether or not beneficially owned by
the undersigned), or any beneficial interest therein for a period of 10 trading
days following the receipt of an advance notice by Advanced Viral pursuant to
the agreement.

         In conjunction with the equity line of credit agreement, we entered
into an agreement with May Davis Group, Inc., our placement agent, pursuant to
which May Davis will receive five percent (5%) of the proceeds from the sale of
common stock to Spinneret Financial Systems under the equity line of credit
agreement. May Davis initiated contact with Spinneret Financial Systems and
assisted Advanced Viral in negotiating the equity line of credit agreement. The
fees will be paid by Advanced Viral upon receipt of funds from Spinneret
Financial Systems. May Davis is not obligated to purchase any of our shares, but
as an additional placement fee, we have issued to May Davis a Class A Warrant to
purchase 5,000,000 shares of our common stock at an exercise price per share
equal to $1.00, exercisable in part or in whole at any time by May Davis at its
discretion until September 18, 2005, and a Class B Warrant to purchase 5,000,000
shares of our common stock at an exercise price equal to the greater of $1.00 or
110% of the bid price of the common stock on the applicable advance date,
exercisable pro rata on the basis of the number of shares of common stock
issuable on each advance date for a period of sixty months from the date of
issuance. We may redeem the warrants at a redemption price of $.01 per share
provided that the bid price for our common stock equals at least $4.00 per share
for a period of ten (10) consecutive trading days, as described therein. The
warrants contain provisions that adjust the purchase price and number of shares
issuable to May Davis upon the occurrence of certain events, such as a stock
split, reverse stock split, stock dividend, merger, or recapitalization.
Assuming a registration statement covering the resale of the shares underlying
the warrants and the equity line of credit is effective and not suspended, May
Davis may effect a cashless exercise of the warrant commencing with the first
advance date. May Davis is also entitled to certain "piggyback" registration
rights with respect to the shares of common stock issuable upon exercise of the
warrants pursuant to a registration rights agreement.


MARKETING AND SALES

         Except for limited sales of Product R for testing and other purposes,
Product R is not sold commercially anywhere in the world. As of the date of this
prospectus, our efforts or the efforts of our representatives have produced no
material benefits to us regarding our ability to have Product R sold
commercially anywhere in the world. We have entered into exclusive distribution
agreements with five separate entities granting exclusive rights to distribute
Product R in the countries of China, Japan, Hong Kong, Macao, Taiwan, Mexico,
Channel Islands, Isle of Man, British West Indies, Jamaica, Haiti, Bermuda,
Belize, Saudi Arabia, Argentina, Bolivia, Paraguay, Uruguay, Brazil and Chile.
Pursuant to these agreements, the distributors are obligated to cause Product R
to be approved for commercial sale in such countries and upon such approval, to
purchase from us certain minimum quantities of Product R to maintain the
exclusive distribution rights. Our marketing plans for Product R are still
dependent upon registration of Product R for sale in various jurisdictions where
our distributors are seeking approvals.

         To date we have received no information that would lead us to believe
that we will be positioned to sell Product R commercially anywhere in the world
in the immediate future, and it is possible that none of our distributors will
ever secure registration of Product R. The only application for registration of
Product R which has been filed as of the date hereof is an application
requesting that Product R be permitted to be sold in Argentina, which was filed
in March 1998. In this March 1998 filing, DCT, S.R.L., our distribution agent in
Argentina, received an investigational new drug identification number from the
National Administration for Drug, Food and Medical Technology in Argentina, or
ANMAT. This allowed DCT to begin pre-clinical studies on our behalf with Product
R which have since been concluded. In February 2000, DCT received approval from
the ANMAT to proceed further with Phase I

                                       31
<PAGE>   35

clinical trials in Argentina for Product R. We are currently evaluating the
costs and time necessary to proceed with Phase I clinical trials in Argentina.
In addition, DCT must apply for approval from the ANMAT to proceed with Phases
II and III clinical trials before Product R is approved for sale in Argentina.
The costs and time necessary to complete such trials cannot be predicted at this
time.

         We initially targeted our sales and marketing efforts to those
countries where Product R was previously marketed by its prior owners for a
number of years as an anti-viral agent in the treatment of Asian influenza,
viral pneumonia, viral infectious hepatitis, mumps, encephalitis, herpes simplex
and herpes zoster. Those countries included Singapore, Hong Kong, Malaysia,
Taiwan, the Philippines and Malta. Registration of Product R will be required in
such countries as well as in the other countries comprising the distributors'
territories before any significant sales may begin. The registration of Product
R for sale in these countries has been frustrated due to our inability to obtain
the registration and approval to sell Product R in the Bahamas, the country of
origin, and a general lack of published data on the effectiveness of Product R.
Until Product R is registered and approved for sale in the United States, in
another developed country or in the other countries included in the
distributors' territories, we will not generate any material sales of Product R.
For the years ended December 31, 1999, 1998 and 1997, we reported no commercial
sales except limited sales for testing purposes. Product R is not legally
available for commercial sale anywhere in the world, except for testing
purposes. See "--Research, Development and Testing."

         By letter dated February 13, 1996, our subsidiary in the Bahamas,
Advance Viral Research, Ltd., was notified that the National Economic Council of
the Bahamas had refused our subsidiary's request for a "free sales certificate"
for Product R. A free sales certificate is a document typically issued by a
country in which a pharmaceutical product is manufactured which certifies that
such country permits the "free sale" of such product in such country. Most
countries require that, before allowing the registration of a pharmaceutical
product for use in that country, it must at least be registered and certified
for free sale in the country in which it is manufactured. However, the Bahamas
has no procedures currently in place to issue a free sales certificate for any
therapeutic drug, including Product R. If we do not obtain a free sales
certificate or other equivalent document from the Bahamas or another country, or
if we do not receive FDA approval, it is possible that we will not be able to
meet registration requirements in the countries which require that a
pharmaceutical product be at least registered and certified for free sale in the
country in which it is manufactured. Currently, we intend to manufacture Product
R in Argentina, where we are seeking regulatory approval and therefore does not
need a free sale certificate for Argentina.

         We are currently in the planning stages for the reconfiguration of our
New York research facilities to enable us to manufacture and produce Product R
if and when the FDA approves Product R for distribution and sale in the United
States.

COMPETITION

         The pharmaceutical drug industry is highly competitive and rapidly
changing. If we ever successfully develop Product R, it will compete with
numerous existing therapies. In addition, many companies are pursuing novel
drugs that target the same diseases we are targeting with Product R. We believe
that a significant number of drugs are currently under development and will
become available in the future for the treatment of HIV, HPV, hepatitis and
other viruses. We anticipate that we will face intense and increasing
competition as new products enter the market and advanced technologies become
available. Our competitors' products may be more effective, or more effectively
marketed and sold, than Product R. Competitive products may render Product R
obsolete or noncompetitive before we can recover the expenses of developing and
commercializing Product R. Furthermore, the development of a cure or new
treatment methods for the diseases we are targeting could render Product R
noncompetitive, obsolete or uneconomical. Many of our competitors:

                                       32
<PAGE>   36

         o        have significantly greater financial, technical and human
                  resources than we have and may be better equipped to develop,
                  manufacture and market products,

         o        have extensive experience in preclinical testing and clinical
                  trials, obtaining regulatory approvals and manufacturing and
                  marketing pharmaceutical products,

         o        have products that have been approved or are in late stage
                  development and operate large, well-funded research and
                  development programs.

         A number of therapeutics are currently marketed or are in advanced
stages of clinical development for the treatment of HIV infection and AIDS,
including several products currently marketed as part of a "cocktail" in the
United States. We believe Product R should be added to such cocktails in order
to enhance their effectiveness. Among the companies with significant commercial
presence in the AIDS market are Glaxo Wellcome, Bristol-Myers Squibb,
Hoffmann-La Roche, Agouron Pharmaceuticals, Merck & Co. and DuPont Pharma. In
addition, Glaxo Wellcome, in collaboration with Biochem Pharma, is pursuing
development of Lamivudine, a nucleoside analogue to treat hepatitis B infection.
This compound was recently approved for marketing in the United States, China
and several other countries and represents significant potential competition for
Product R as a treatment for hepatitis B.

         Several therapeutics are currently marketed or are in advanced stages
of clinical development for the treatment of HPV. Schering Plough Corp.
manufactures Intron A, an injectable interferon product approved by the FDA for
the treatment of HPV. 3M Pharmaceuticals received FDA approval for its
immune-response modifier, Aldara(R), a self-administered topical cream, for the
treatment of HPV. Product R, if approved for commercial sale by the FDA, would
also compete with surgical, chemical, and other methods of treating HPV.
Products developed by our competitors or advances in other methods of the
treatment of HPV may have a negative impact on the commercial viability of
Product R.

         Several products are currently marketed or are in advanced stages of
clinical development for the treatment of rheumatoid arthritis. Immunex Corp.'s
product Enbrel, a biologic response modifier, was approved by the FDA in
November 1998 for the treatment of moderate to severe rheumatoid arthritis.
Centocor Inc. is developing a monoclonal antibody known as Remicade, an
anti-inflammatory agent that has completed phase III trials in rheumatoid
arthritis. The FDA approved Remicade for treatment of Crohn's disease in August
1998. Centocor filed for FDA approval of an expanded indication for Remicade for
rheumatoid arthritis in January 1999. These products represent significant
competition for Product R as a treatment for rheumatoid arthritis.

         Three antiviral products are presently sold in the United States for
the treatment of recurrent genital herpes: Zovirax(R) (manufactured by Glaxo
Wellcome Inc.) which contains acyclovir and is administered orally, topically,
or intravenously, Famvir(R) (manufactured by SmithKline Beecham Pharmaceuticals)
which contains famcyclovir and is administered orally, and Valtrex(R)
(manufactured by Glaxo Wellcome, Inc.) which contains valacyclovir and is also
administered orally. These products represent significant competition for
Product R as a treatment for genital herpes.

         Other small companies may also prove to be significant competitors,
particularly through collaborative arrangements with large pharmaceutical and
biotechnology companies. Academic institutions, governmental agencies and other
public and private research organizations are also becoming increasingly aware
of the commercial value of their inventions and are more actively seeking to
commercialize the technology they have developed.

                                       33
<PAGE>   37

         If we successfully develop and obtain approval for Product R, we will
face competition based on the safety and effectiveness of Product R, the timing
and scope of regulatory approvals, the availability of supply, marketing and
sales capability, reimbursement coverage, price, patent position and other
factors. Our competitors may develop or commercialize more effective or more
affordable products, or obtain more effective patent protection, than we do.
Accordingly, our competitors may commercialize products more rapidly or
effectively than we do, which could hurt our competitive position and adversely
affect our business. If and when we obtain FDA approval for Product R, we expect
to compete primarily on the basis of product performance and price with a number
of pharmaceutical companies, both in the United States and abroad.

EMPLOYEES

         We have 27 full-time employees, consisting of our 4 executive officers,
18 employees involved in research, and 5 administrative employees. Dr.
Hirschman, our President and Chief Executive Officer and a director, Bernard
Friedland, our Chairman of the Board and a director, William Bregman, our
Secretary, Treasurer and a director, and Alan V. Gallantar, our Chief Financial
Officer, each devote all of their business time to our day-to-day business
operations. Additionally, we may hire, as and when needed, and as available,
such sales and technical support staff and consultants for specific projects on
a contract basis. See "Management --Employment Contracts, Termination of
Employment and Change-in-Control Arrangements."

PROPERTY

         We lease approximately 16,650 square feet for executive offices,
including research laboratory space, at 200 Corporate Boulevard South, Yonkers,
New York from an unaffiliated third party (the "Yonkers Lease"). The term of the
Yonkers Lease is five years through April 2005 and our annual rental obligation
under the Yonkers Lease is approximately $260,000.

         We currently maintain corporate offices at 1250 East Hallandale Beach
Boulevard, Hallandale, Florida 33009, pursuant to a three year lease agreement,
at approximately $14,000 annually. The Bahamian manufacturing facility, which
was acquired on December 16, 1987, is located in Freeport, Bahamas and consists
of a 29,242 square foot site containing a one-story concrete building of
approximately 7,300 square feet and is equipped for all phases of the testing,
production, and packaging of Product R. The Bahamian facility is currently being
used to store and produce inventory for testing purposes.

LEGAL PROCEEDINGS

         In June 2000, Advanced Viral filed an action and complaint in the
Supreme Court of New York, Westchester County, against Commonwealth
Pharmaceuticals, Ltd., Immune Modulation Maximum Corp. ("IMMC") and Charles E.
Miller (collectively, the "Defendants") alleging a breach by Commonwealth of an
exclusive distribution agreement between Advanced Viral and Commonwealth,
misappropriation of trade secrets and confidential information, conversion and
conspiracy to convert Advanced Viral's property interests in Reticulose.
Advanced Viral further alleged that Defendant Miller filed and obtained a U.S.
patent entitled "Composition Containing Peptides and Nucliec Acids and Methods
of Making Same" based on a study conducted by a third party using Reticulose,
and that such patent was assigned to Defendant IMMC, a company controlled by
Defendant Miller, in violation of the exclusive distribution agreement.

                                       34
<PAGE>   38

         In its complaint, Advanced Viral seeks relief in the form of (i)
assignment of the patent to Advanced Viral, (ii) adjudgment that Defendants
breached, misappropriated, converted and conspired to convert Advanced Viral's
property rights, (iii) damages, profits realized and interest thereon; and (iv)
attorneys' fees, costs and expenses. In response, on August 3, 2000, Defendants
filed a Motion to Dismiss the Complaint alleging lack of personal jurisdiction
or, in the alternative, that the agreement underlying Advanced Viral's claim is
legally inoperative.

         In August 2000, the Defendants other than Miller, filed a suit against
Advanced Viral in the United States District Court for the Eastern District of
Michigan which alleges that IMMC, and not Advanced Viral, is the owner of the
exclusive/broad rights in Reticulose, and seeks, among other things: (i) a
declaratory judgment that Defendant IMMC is the exclusive owner of the
broad/exclusive rights to Reticulose and the subject patent; (ii) an injunction
against Advanced Viral from further attempts to use, market or assert any claims
of ownership over any broad/exclusive rights in Reticulose, or the use,
publication or disclosure of information regarding Reticulose; (iii) return of
such information to the Defendants; (iv) that Advanced Viral assign any
Reticulose-related trademarks to IMMC and (v) that Advanced Viral pay Defendants
damages, profits, costs and attorneys' fees. Advanced Viral was served with a
copy of the Complaint on August 8, 2000.


         In September 2000, our case in New York was dismissed. We are
considering requesting that the New York court reinstate our claims in the New
York case. The case in the federal court in Detroit continues. At this point, we
have answered the complaint against us in the federal court in Detroit and have
entered a number of counterclaims which are in substance the same as our claims
in the New York case.


         Advanced Viral believes that the allegations contained in the
Defendants' complaint are without merit and Advanced Viral intends to vigorously
defend itself against all allegations contained therein.

                  automobile.

         o        We will reimburse Mr. Gallantar for certain professional
                  license and membership fees up to a maximum of $5,000 per year
                  in the aggregate, and all other expenses incurred in the
                  performance of his duties with the prior approval of the Chief
                  Executive Officer.

         o        If Mr. Gallantar relocates his primary residence to
                  Westchester County, New York, or New York City prior to the

                  moving, legal and brokerage fees or costs incurred by him in
                  connection with such relocation up to a maximum of $15,000.

         The agreement provides that Mr. Gallantar is not authorized, without

each of the selling shareholders assuming the full exercise of certain warrants
and stock options. Unless otherwise indicated below, to our knowledge all
persons listed below have sole voting and investment power with respect to the
shares of common stock, except to the extent authority is shared by spouses
under applicable law. The information included below is based upon information
provided by the selling shareholders. Because the selling shareholders may offer
all, some or none of their shares, no definitive estimate as to the number of
shares that will be held by the selling shareholders after such offering can be
provided and the following table has been prepared on the assumption that all
shares offered under this prospectus will be sold.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         For the past three fiscal years, there were no material transactions
between Advanced Viral and any of our officers or directors which involved
$60,000 or more.

                           DESCRIPTION OF COMMON STOCK


         As of the date of this prospectus, our Certificate of Incorporation
authorize us to issue 1,000,000,000 shares of common stock, par value $0.00001
per share. As of September 21, 2000, there were outstanding 361,729,385 shares
of common stock, all of which are fully paid for and non-assessable. The holders
of common stock:


         o        have equal ratable rights to dividends from funds legally
                  available therefore, when, as and if declared by our board of
                  directors;

         o        entitled to share ratably in all of our assets available for
                  distribution to holders of common stock upon liquidation,
                  dissolution or winding up of our affairs;

         o        do not have preemptive, subscription, or conversion rights and
                  there are no redemption or sinking fund provisions applicable
                  thereto; and


         o        are entitled to one noncumulative vote per share on all
                  matters which shareholders may vote on at all meetings of
                  shareholders.


         American Stock Transfer & Trust Company is our transfer agent and
registrar, and is located in Brooklyn, New York.

                                 USE OF PROCEEDS

         We will not receive any proceeds from the sale of common stock by the
selling shareholders. We will receive the cash proceeds, if any, from the
exercise of any of the warrants held by the selling shareholders.

                              PLAN OF DISTRIBUTION

         Sales of the shares may be made from time to time by the selling
shareholders, or, subject to applicable law, by pledgees, donees, distributees,
transferees or other successors in interest. Such sales may be made on the OTC
Bulletin Board, in another over-the-counter market, on a national securities
exchange (any of which

                                       43
<PAGE>   47

may involve crosses and block transactions) or other market on which our common
stock may be listed at the time of sale, including the American Stock Exchange,
in privately negotiated transactions or otherwise or in a combination of such
transactions at prices and at terms then prevailing or at prices related to the
then current market price, or at privately negotiated prices or at fixed prices
that may be changed. In addition, any shares covered by this prospectus which
qualify for sale pursuant to Section 4(l) of the Securities Act or Rule 144
promulgated thereunder may be sold under such provisions rather than pursuant to
this prospectus. We will also receive the cash proceeds, if any, from the
exercise of any of the warrants held by the selling shareholders. Without
limiting the generality of the foregoing, the shares may be sold in one or more
of the following types of transactions:

         o        a block trade in which the broker-dealer so engaged will
                  attempt to sell the shares as agent but may position and
                  resell a portion of the block as principal to facilitate the
                  transaction;

         o        purchases by a broker or dealer as principal and resale by
                  such broker or dealer for its account pursuant to this
                  prospectus;

         o        an exchange distribution in accordance with the rules of such
                  exchange;

         o        ordinary brokerage transactions and transactions in which the
                  broker solicits purchasers; and

         o        face-to-face transactions between sellers and purchasers
                  without a broker-dealer. In effecting sales, brokers or
                  dealers engaged by the selling shareholders may arrange for
                  other brokers or dealers to participate in the resales.

         Such broker-dealers, if any, may receive compensation in the form of
discounts, concessions or commissions from the selling shareholder and/or the
purchasers of the shares of common stock for whom such broker-dealers may act as
agents or to whom they may sell as principals, or both (which compensation, as a
particular broker-dealer, might be in excess of customary commissions).

         In connection with distributions of the shares or otherwise, the
selling shareholders may enter into hedging transactions with broker-dealers. In
connection with such transactions, broker-dealers may engage in short sales of
the shares registered hereunder in the course of hedging the positions they
assume with selling shareholders. The selling shareholders may also sell shares
short and deliver the shares to close out such short positions. The selling
shareholders may also enter into option, swaps, derivatives or other
transactions with broker-dealers which require the delivery to the broker-dealer
of the shares registered hereunder, which the broker-dealer may resell pursuant
to this prospectus. The selling shareholders may also pledge the shares
registered hereunder to a broker or dealer and upon a default, the broker or
dealer may effect sales of the pledged shares pursuant to this prospectus.

         From time to time the selling shareholders may be engaged in short
sales, short sales against the box, puts and calls and other hedging
transactions in our securities, and may sell and deliver the shares in
connection with such transactions or in settlement of securities loans. These
transactions may be entered into with broker-dealers or other financial
institutions. In addition, from time to time, a selling shareholder may pledge
its shares pursuant to the margin provisions of its customer agreements with its
broker-dealer. Upon delivery of the shares or a default by a selling
shareholder, the broker-dealer or financial institution may offer and sell the
pledged shares from time to time.

         Brokers, dealers or agents may receive compensation in the form of
commissions, discounts or concessions from selling shareholders in amounts to be
negotiated in connection with the sale. Such brokers or dealers and any other
participating brokers or dealers may be deemed to be 'underwriters' within the

                                       44
<PAGE>   48

meaning of the Securities Act in connection with such sales and any such
commission, discount or concession may be deemed to be underwriting discounts or
commissions under the Securities Act.

         Information as to whether underwriters who may be selected by the
selling shareholders, or any other broker-dealer, is acting as principal or
agent for the selling shareholders, the compensation to be received by
underwriters who may be selected by the selling shareholders, or any
broker-dealer, acting as principal or agent for the selling shareholders and the
compensation to be received by other broker-dealers, if the compensation of such
other broker-dealers is in excess of usual and customary commissions, will, to
the extent required, be set forth in a supplement to this prospectus. Any dealer
or broker participating in any distribution of the shares may be required to
deliver a copy of this prospectus, including the prospectus supplement, if any,
to any person who purchases any of the shares from or through such dealer or
broker.

         We have advised the selling shareholders that during such time as they
may be engaged in a distribution of the shares included in this prospectus they
are required to comply with Regulation M promulgated under the Exchange Act.
With certain exceptions, Regulation M precludes any selling shareholders, any
affiliated purchasers and any broker-dealer or other person who participates in
such distribution from bidding for or purchasing, or attempting to induce any
person to bid for or purchase any security which is the subject of the
distribution until the entire distribution is complete. Regulation M also
prohibits any bids or purchases made in order to stabilize the price of a
security in connection with the distribution of that security. All of the
foregoing may affect the marketability of the common stock.

         It is anticipated that the selling shareholders will offer all of the
shares for sale. Further, because it is possible that a significant number of
shares could be sold at the same time under this prospectus, such sales, or the
possibility of such sales, may have a depressive effect on the market price of
our common stock. None of the selling shareholders have entered into any
agreements regarding the sales of the shares being registered.

         We have agreed to bear all expenses of registration of the shares of
common stock offered by the selling shareholders for resale, other than any
commissions, discounts, concessions or other fees, if any, payable to
broker-dealers in connection with any sale of the shares of common stock, which
will be borne by the selling shareholder selling those shares or by the
purchasers of such shares.

         We have agreed to indemnify each selling shareholder or their
transferees or assignees against certain liabilities, including liabilities
under the Securities Act of 1933, or to contribute to payments to which such
selling shareholder or its pledgees, donees, transferees or other successors in
interest may be required to make in respect thereof.

                                  LEGAL MATTERS

         The validity of the shares offered in this prospectus will be passed

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

Stockholders and Directors
Advanced Viral Research Corp.
  (A Development Stage Company)
Yonkers, New York

We have audited the accompanying consolidated balance sheets of Advanced Viral
Research Corp. (A Development Stage Company) as of December 31, 1999 and 1998,
and the related consolidated statements of operations, stockholders' equity
(deficiency) and cash flows for each of the years in the three year period ended
December 31, 1999 and for the period from inception (February 20, 1984) to
December 31, 1999. These consolidated financial statements are the
responsibility of the management of the Company. 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 consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated 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 Advanced Viral
Research Corp. (A Development Stage Company) as of December 31, 1999 and 1998
and the results of their operations and their cash flows for each of the years
in the three year period ended December 31, 1999 and for the period from
inception (February 20, 1984) to December 31, 1999 in conformity with generally
accepted accounting principles.

The accompanying consolidated financial statements have been prepared assuming
that the Company will continue as a going concern. As discussed in Note 2 to the
consolidated financial statements, the Company has suffered recurring losses
from operations and is dependent upon the continued sale of its securities or
obtaining debt financing for funds to meet its cash requirements. These factors
raise substantial doubt about the Company's ability to continue as a going
concern. Management's plans with regard to these matters are also described in
Note 2. The consolidated financial statements do not include any adjustments
that might result from the outcome of this uncertainty.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                           DECEMBER 31, 1999 AND 1998


NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         BUSINESS

             Advanced Viral Research Corp. (the Company) was incorporated in
             Delaware on July 31, 1985. The Company was organized for the
             purpose of manufacturing and marketing a pharmaceutical product
             named Reticulose (the current formulation of which is now known as
             and hereinafter referred to as "Product R"). While the Company has
             had limited sales of this product, primarily for research purposes,
             the success of the Company will be dependent upon obtaining certain
             regulatory approval for its pharmaceutical product, Product R, to
             commence commercial operations.

         PRINCIPLES OF CONSOLIDATION

             The consolidated financial statements include the accounts of the
             Company and its 99.6% owned subsidiary, Advance Viral Research,
             Ltd. (LTD), a Bahamian Corporation. All significant intercompany
             accounts have been eliminated.

         DEVELOPMENT STAGE ENTERPRISE

             As described above, the Company was incorporated on July 31, 1985,
             and, since that time, has been primarily involved in organizational
             activities, research and development activities, and raising
             capital. Planned operations, as described above, have not commenced
             to any significant extent. Accordingly, the Company is considered
             to be in the development stage, and the accompanying consolidated
             financial statements represent those of a development stage
             enterprise.

         CASH AND CASH EQUIVALENTS

             Cash equivalents consist of highly liquid investments (money fund),
             with original maturities of three months or less.

         INVESTMENTS

             At December 31, 1999, investments consist of a money fund, which is
             reported at its fair value. At December 31, 1998, investments
             consisted of U.S. Government discount notes classified as "held to
             maturity" and are carried at amortized cost, which approximates
             fair value.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Continued)




NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

         PROPERTY AND EQUIPMENT

             Property and equipment are stated at cost. Depreciation is computed
             using the straight-line method, over the estimated useful lives of
             the assets. Gain or loss on disposition of assets is recognized
             currently. Maintenance and repairs are charged to expense as
             incurred. Major replacements and betterments are capitalized and
             depreciated over the remaining useful lives of the assets.

         RESEARCH AND DEVELOPMENT

             Research and development costs are expensed as incurred by the
             Company.

         INCOME TAXES

             The Company accounts for its income taxes using Statement of
             Financial Accounting Standards (SFAS) No. 109, ACCOUNTING FOR
             INCOME TAXES, which requires recognition of deferred tax
             liabilities and assets for expected future tax consequences of
             events that have been included in the financial statements or tax
             returns. Under this method, deferred tax liabilities and assets are
             determined based on the differences between the financial statement
             and tax bases of assets and liabilities using enacted tax rates in
             effect for the year in which the differences are expected to
             reverse.

         ESTIMATED FAIR VALUE OF FINANCIAL INSTRUMENTS

             The information set forth below provides disclosure of the
             estimated fair value of the Company's financial instruments
             presented in accordance with the requirements of Statement of
             Financial Accounting Standards (SFAS) No. 107. Fair value estimates
             discussed herein are based upon certain market assumptions and
             pertinent information available to management as of December 31,
             1999 and 1998. Since the reported fair values of financial
             instruments are based upon a variety of factors, they may not
             represent actual values that could have been realized as of
             December 31, 1999 and 1998 or that will be realized in the future.

             The respective carrying value of certain on-balance-sheet financial
             instruments approximated their fair values. These financial
             instruments include cash, a money fund, U.S. government
             obligations, accounts payable and the convertible debentures. Fair
             values were assumed to approximate carrying values for these
             financial instruments since they are short-term in nature and their
             carrying amounts approximate fair values or they are receivable or
             payable on demand.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Continued)




NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

         ESTIMATED FAIR VALUE OF FINANCIAL INSTRUMENTS (Continued)

             At December 31, 1998, the fair value of non-current investments,
             primarily U.S. government obligations, have been estimated using
             quoted market prices. The differences between the estimated fair
             value and the carrying value of non-current and current debt
             instruments were considered immaterial in relation to the Company's
             financial position.

         CONCENTRATIONS OF CREDIT RISk

             Financial instruments that potentially subject the Company to
             concentrations of credit risk consist principally of cash. At
             various times during the year, the Company has cash balances in
             excess of federally insured limits. The Company maintains its cash,
             which consists primarily of demand deposits, with high quality
             financial institutions, which the Company believes limits risk.

         STOCK-BASED COMPENSATION

             The Company has elected to follow Accounting Principles Board
             Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES (APB No.
             25), and related interpretations, in accounting for its employee
             stock options rather than the alternative fair value accounting
             allowed by SFAS No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION.
             APB No. 25 provides that the compensation expense relative to the
             Company's employee stock options is measured based on the intrinsic
             value of the stock option. SFAS No. 123 requires companies that
             continue to follow APB No. 25 to provide a pro-forma disclosure of
             the impact of applying the fair value method of SFAS No. 123.

             The Company follows SFAS No. 123 in accounting for stock options
             issued to non-employees.

         NET LOSS PER COMMON SHARE

             The Company computes loss per share in accordance with SFAS No.
             128, EARNINGS PER SHARE, which was adopted in 1997. This standard
             requires dual presentation of basic and diluted earnings per share
             on the face of the income statement for all entities with complex
             capital structures and requires a reconciliation of the numerator
             and denominator of the diluted earnings per share computation.

             Net loss per common share (basic and diluted) is based on the net
             loss divided by the weighted average number of common shares
             outstanding during the year.

             The Company's potentially issuable shares of common stock pursuant
             to outstanding stock options are excluded from the Company's
             diluted computation, as their effect would be anti-dilutive.

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

         REVENUE RECOGNITION

             The limited sales generated by the Company have consisted of sales
             of Product R for testing and other purposes. The Company records
             sales when the product is shipped to customers.

         RECLASSIFICATIONS

             Certain amounts in the 1997 and 1998 financial statements have been
             reclassified to conform to 1999 presentation.

         USE OF ESTIMATES

             The preparation of financial statements in conformity with
             generally accepted accounting principles requires management to
             make estimates and assumptions that affect the amounts reported in
             the financial statements and accompanying notes. Although these
             estimates are based on management's knowledge of current events and
             actions it may undertake in the future, they may ultimately differ
             from actual results.

         RECENT ACCOUNTING PRONOUNCEMENTS

             In June 1998, the Financial Accounting Standards Board issued SFAS
             No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING
             ACTIVITIES. SFAS No. 133 requires companies to recognize all
             derivatives contracts as either assets or liabilities in the
             balance sheet and to measure them at fair value. If certain
             conditions are met, a derivative may be specifically designated as
             a hedge, the objective of which is to match the timing of the gain
             or loss recognition on the hedging derivative with the recognition
             of (i) the changes in the fair value of the hedged asset or
             liability that are attributable to the hedged risk 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 in income in the period of change. On June 30, 1999,

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Continued)



NOTE 2.  BASIS OF PRESENTATION

         The accompanying consolidated financial statements have been prepared
         in conformity with generally accepted accounting principles, which
         contemplate the continuance of the Company as a going concern. The
         Company has suffered losses from operations during its history. The
         Company is dependent upon registration of Product R for sale before it
         can begin commercial operations. The Company's cash position may be
         inadequate to pay all the costs associated with the full range of
         testing and clinical trials required by the FDA. Unless and until
         Product R is approved for sale in the United States or another
         industrially developed country, the Company may be dependent upon the
         continued sale of its securities and debt financing for funds to meet
         its cash requirements. Management intends to continue to sell the
         Company's securities in an attempt to mitigate the effects of its cash
         position; however, no assurance can be given that equity or debt
         financing, if and when required, will be available.

         During 1999 and 1998, the Company was successful in obtaining equity
         and debt financing aggregating approximately $3,700,000 and $2,400,000,
         respectively. No assurance can be given that the Company will be able
         to sustain its operations until FDA approval is granted or that any
         approval will ever be granted, or that the Company will be successful
         in the efforts to obtain equity or debt financing. These factors raise
         substantial doubt about the Company's ability to continue as a going
         concern. The Company expects to submit an application for approval with
         the FDA in the near future, and plans to continue to seek additional
         equity and debt financing as the need arises. The consolidated
         financial statements do not include any adjustments relating to the
         recoverability and classification of recorded assets and classification
         of liabilities that might be necessary should the Company be unable to
         continue in existence.

NOTE 3.  ACQUISITION

         Two of the principal stockholders of the Company acquired LTD, a
         Bahamian Corporation with pharmaceutical manufacturing and warehousing
         facilities, on February 20, 1984. The acquisition is a combination of
         two entities under common control and has been accounted for in a
         manner similar to a pooling of interests. In 1986, the Company acquired
         from LTD exclusive rights to manufacture and market Reticulose
         (currently referred to as Product R) worldwide, except within the
         Bahamas, for $50,000. The Company also purchased inventory of Product R
         from LTD for $45,000 and was obligated to pay $3 per ampule of Product
         R for the initial 100,000 ampules purchased and $2 per ampule for
         purchases exceeding 100,000 ampules. On December 16, 1987, the Company
         acquired the controlling beneficial interest in 99.6% of the common
         stock of LTD through an appropriate trust agreement to satisfy the
         rules of the Bahamian Government, from two of the principal
         stockholders of the Company. Both stockholders concurrently canceled
         $86,565 of indebtedness due them from LTD.

         Patent development costs are capitalized as incurred. Loan costs relate
         to fees paid in connection with the issuance of convertible debentures
         (Note 8) and are amortized over the life of the debenture or until
         conversion.

         CONVERTIBLE DEBENTURES

             In February 1997 and October 1997, in order to finance research and
             development, the Company sold $1,000,000 and $3,000,000,
             respectively, principal amount of its ten-year 7% Convertible
             Debentures (the "February Debenture" and the "October Debenture",
             collectively, the "Debentures") due February 28, 2007 and August
             30, 2007, respectively, to RBB Bank Aktiengesellschaft ("RBB") in
             offshore transactions pursuant to Regulation S under the Securities
             Act of 1933, as amended. Accrued interest under the Debentures was
             payable semi-annually, computed at the rate of 7% per annum on the
             unpaid principal

             balance from the date of issuance until the date of interest
             payment. The Debentures were convertible, at the option of the
             holder, into shares of Common Stock pursuant to specified formulas.
             On April 22, 1997, June 6, 1997, July 3, 1997 and August 20, 1997,
             pursuant to notice by the holder, RBB, to the Company under the
             February Debenture, $330,000, $134,000, $270,000 and $266,000,
             respectively, of the principal amount of the February Debenture was
             converted into 1,648,352, 894,526, 2,323,580 and 1,809,524 shares
             of the Common Stock, respectively. As of August 20, 1997, the
             February Debenture was fully converted. On December 9, 1997,
             January 7, 1998, January 14, 1998, February 19, 1998, February 23,
             1998, March 31, 1998, May 4, 1998 and May 5, 1998, pursuant to
             notice by the holder, RBB, to the Company, $120,000, $133,000,
             $341,250, $750,000, $335,750, $425,000, $275,000 and $620,000,
             respectively, of the October Debenture was converted into 772,201,
             1,017,011, 2,512,887, 5,114,218, 1,498,884, 1,870,869, 1,491,485
             and 3,299,979 Common Stock, respectively. As of May 5, 1998, the
             October Debenture was fully converted.

             In connection with the issuance of the February Debenture, the
             Company issued to RBB three warrants (the "February Warrants") to
             purchase common stock, each such February Warrant entitling the
             holder to purchase, from February 21, 1997 through February 28,
             2007, 178,378 shares of common stock. The exercise price of the
             three February Warrants was $0.288, $0.576 and $0.864 per warrant
             share, respectively. The fair value of the February Warrants was
             estimated to be $37,000 ($.021 per warrant) based upon a financial
             analysis of the terms of the warrants using the Black-Sholes
             Pricing Model. This amount has been reflected in the accompanying
             financial statements as interest expense related to the convertible
             February Debenture. Based on the terms for conversion associated
             with the February Debenture, there was an intrinsic value
             associated with the beneficial conversion feature of $413,793. This
             amount has been fully amortized to interest expense with a
             corresponding credit to additional paid-in capital.

             In connection with the issuance of the October Debenture, the
             Company issued to RBB three warrants (the "October Warrants") to
             purchase Common Stock, each such October Warrant entitling the
             holder to purchase, from the date of grant through August 30, 2007,
             600,000 shares of the Common Stock. The exercise price of the three
             October Warrants was $0.20, $0.23 and $0.27 per warrant share,
             respectively. The fair value of the three October Warrants was
             established to be $106,571 ($.178 per warrant), $97,912 ($.163 per
             warrant) and $87,472 ($.146 per warrant), respectively, based upon
             a financial analysis of the terms of the warrants using the
             Black-Sholes Pricing Model. This amount has been reflected in the
             accompanying financial statements as a discount on the convertible
             debenture, with a corresponding credit to additional paid-in
             capital, and is being amortized over the expected term of the
             notes, which at December 31, 1997 was 120 months. In May 1998, the
             remaining unamortized discount of $276,957 was amortized upon full
             conversion of the October Debenture.

         CONVERTIBLE DEBENTURES (Continued)

             Based on the terms for conversion associated with the October
             Debenture, there was an intrinsic value associated with the
             beneficial conversion feature of $1,350,000. This amount has been
             treated as deferred interest expense and recorded as a reduction of
             the convertible debenture liability with a corresponding credit to
             additional paid-in capital and has been amortized to interest
             expense over the period from October 8, 1997 (date of debenture) to
             February 24, 1998 (date the debenture was fully convertible). The
             interest expense relative to this item was $210,951 for 1998 and
             $1,139,049 for 1997.

             In November 1998, in order to finance further research and
             development, the Company sold $1,500,000 principal amount of its
             ten year 7% Convertible Debenture (the "November Debenture") due
             October 31, 2008, to RBB. Accrued interest under the November
             Debenture is payable semi-annually, computed at the rate of 7% per
             annum on the unpaid principal balance from the date of the issuance
             of the November Debenture until the date of interest payment. The
             November Debenture may be prepaid by the Company before maturity,
             in whole or in part, without premium or penalty, if the Company
             gives the holder of the Debenture notice not less than 30 days
             before the date fixed for prepayment in that notice. The November
             Debenture is convertible, at the option of the holder, into shares
             of common stock.

             In connection with the issuance of the November Debenture, the
             Company issued to RBB two warrants (the "November Warrants") to
             purchase Common Stock, each such November Warrant entitling the
             holder to purchase 375,000 shares of the Common Stock at any time
             and from time to time through October 31, 2008. The exercise price
             of the two November Warrants is $.20 and $.24 per warrant share,
             respectively. The fair value of the November warrants was estimated
             to be $48,000 ($.064 per warrant) based upon a financial analysis
             of the terms of the warrants using the Black-Sholes Pricing Model
             with the following assumptions: expected volatility of 20%; a risk
             free interest rate of 5.75% and an expected holding period of one
             year. This amount is being amortized to interest expense in the
             accompanying consolidated financial statements.

             Based on the terms for conversion associated with the November
             Debenture, there was an intrinsic value associated with the
             beneficial conversion feature of $625,000. This amount has been
             recorded as interest expense in 1998.

             In August 1999, in order to finance further research and
             development, the Company entered into a securities purchase
             agreement to issue an aggregate of 20 units, each unit consisting
             of $100,000 principal amount of the Company's 7% convertible
             debenture (the "August Debenture") due August 3, 2009 to Focus

         CONVERTIBLE DEBENTURES (Continued)

             the August Debenture is payable semi-annually, computed at the rate
             of 7% on the unpaid principal balance from the date of issuance
             until the date of the interest payment. No payment of the principal
             of the August Debenture may be made prior to the maturity date
             without the consent of the holder. The August Debenture is
             convertible, at the option of the holder, into shares of common
             stock.

             In connection with the issuance of the August Debenture, the
             Company issued to Focus one warrant (the "August Warrant") to
             purchase Common Stock, such August Warrant entitling the holder to
             purchase 1,000,000 shares of the Common Stock at any time and from
             time to time through August 3, 2004. The exercise price of the
             August Warrant is $.2461 per warrant share. The fair value of the
             August Warrants was estimated to be $52,593 ($.0526 per warrant
             share) based upon a financial analysis of the terms of the warrant
             using the Black-Scholes Pricing Model with the following
             assumptions: expected volatility of 20%; a risk free interest rate
             of 5.75% and an expected holding period of five years. This amount
             is being amortized to interest expense in the accompanying
             consolidated financial statements.

             Based on the terms for conversion associated with the August
             Debenture, there was an intrinsic value associated with the
             beneficial conversion feature of $687,500. This amount has been
             recorded as interest expense in 1999.

             In December 1999, in order to finance further research and
             development, the Company entered into a securities purchase
             agreement to sell $2,000,000 principal amount of the Company's 7%
             convertible debenture (the December Debenture) due December 28,
             2009 to Endeavour Capital ("Endeavour"). Accrued interest under the
             December Debenture is payable semi-annually, computed at the rate
             of 7% on the unpaid principal balance from the date of issuance
             until the date of the interest payment. No payment of the principal
             of the December Debenture may be made prior to the maturity date
             without the consent of the holder. The December Debenture is
             convertible, at the option of the holder, into shares of common
             stock.

             During 1999, $1,000,000 of these debentures were sold. The
             remaining $1,000,000 was not available until the shares underlying
             the first $1,000,000 were registered. Such registration statement
             was declared effective in January 2000 and the remaining $1,000,000
             transaction was consummated. See Subsequent Event, Note 12.

         CONVERTIBLE DEBENTURES (Continued)

             In connection with the issuance of the December Debenture, the
             Company issued to Endeavour warrants (the December Warrants) to
             purchase Common Stock, such December Warrant entitling the holder
             to purchase 100,000 shares of the Common Stock at any time and from
             time to time through December 31, 2002. The exercise price of the
             December Warrant is $.19 per warrant share. The fair value of the
             December Warrants was estimated to be $4,285 ($.0429 per warrant
             share) based upon a financial analysis of the terms of the warrant
             using the Black-Scholes Pricing Model with the following
             assumptions: expected volatility of 20%; a risk free interest rate
             of 6% and an expected holding period of three years. This amount is
             being amortized to interest expense in the accompanying
             consolidated financial statements.

             Based on the terms for conversion associated with the December
             Debenture, there was an intrinsic value associated with the
             beneficial conversion feature of $357,143. This amount has been
             recorded as interest expense in 1999.

         OTHER

             In January 1999, pursuant to a securities purchase agreement dated
             December 1998, the Company issued 4,917,276 shares of its common
             stock for an aggregate purchase price of $802,500. Such agreement
             also provided for the issuance of four warrants to purchase a total
             of 2,366,788 shares of common stock at prices ranging from $.204 to
             $.2448 per share at any time until December 31, 2003. The fair
             value of these warrants was estimated to be $494,138 ($.209 per
             warrant) based upon a financial analysis of the terms of the
             warrants using the Black-Sholes Pricing Model with the following
             assumptions: expected volatility of 20%; a risk free interest rate
             of 6% and an expected holding period of five years. This amount is
             being amortized to interest expense in the accompanying

             Included in interest expense for the year ended December 31, 1999
             is $256,000, which may be payable by the Company as additional
             financing costs related to the effective date of a registration
             statement covering the resale of certain securities sold by the
             Company.

             On June 23, 1999, the Company entered into a securities purchase
             agreement with certain individuals whereby the Company will issue
             1,851,852 shares of its common stock for an aggregate purchase
             price of $500,000. These proceeds were received in July 1999. Such
             agreement also provides for the issuance of warrants to purchase an
             aggregate of 925,926 shares of common stock at any time until June
             30, 2004. The fair value of these warrants was estimated to be
             $37,000 ($.04 per warrant) based upon a financial analysis of the
             terms of the warrants using the Black-Sholes Pricing Model with the
             following assumptions: expected volatility of 20%; a risk free
             interest rate of 5.75% and an expected holding period of five
             years. This amount is being amortized to interest expense.

NOTE 7.  NOTE PAYABLE

         During 1999, the Company entered into an installment purchase agreement
         for equipment totaling $123,600. The agreement is collateralized by the
         property and calls for monthly installments of $2,476 at 12% per annum
         for 60 months, commencing in March 1999 and expiring in February 2004.

         The aggregate maturities of the installment purchase agreement for each
         of the five years subsequent to December 31, 1999 are as follows:

NOTE 8.  COMMITMENTS AND CONTINGENCIES

         GENERAL

         POTENTIAL CLAIM FOR ROYALTIES

             The Company may be subject to claims from certain third parties for
             royalties due on sale of Product R. The Company has not as yet
             received any notice of claim from such parties.

         PRODUCT LIABILITY

             The Company could be subjected to claims for adverse reactions
             resulting from the use of Product R. Although the Company is
             unaware of any such claims or threatened claims since Product R was
             initially marketed in the 1940's, one study noted adverse reactions
             from highly concentrated doses in guinea pigs. In the event any
             claims for substantial amounts were successful, they could have a
             material adverse effect on the Company's financial condition and on
             the marketability of Product R. As of the date hereof, the Company
             does not have product liability insurance for Product R. There can
             be no assurance that the Company will be able to secure such
             insurance in adequate amounts, at reasonable premiums if it
             determined to do so. Should the Company be unable to secure such
             product liability insurance, the risk of loss to the Company in the
             event of claims would be greatly increased and could have a
             material adverse effect on the Company.

         LACK OF PATENT PROTECTION

             The Company has three issued patents and one allowed patent for the
             use of Product R. The Company currently has 15 patent applications
             pending with the U.S. Patent Office and 17 foreign patent
             applications. The Company can give no assurance that other
             companies, having greater economic resources, will not be
             successful in developing a similar product. There can be no
             assurance that such patents, if obtained, will be enforceable.

         TESTING AGREEMENTS

         PLATA PARTNERS LIMITED PARTNERSHIP

             On March 20, 1992, the Company entered into an agreement with Plata
             Partners Limited Partnership ("Plata") pursuant to which Plata
             agreed to perform a demonstration in the Dominican Republic in
             accordance with a certain agreed upon protocol (the "Protocol") to
             assess the efficacy of a treatment using Product R incorporated in
             the Protocol against AIDS (the "Plata Agreement"). Plata covered
             all costs and expenses associated with the demonstration.

         GENERAL (Continued)

         PLATA PARTNERS LIMITED PARTNERSHIP (Continued)

             Pursuant to the Plata Agreement, the Company authorized the
             issuance to Plata of 5,000,000 shares of common stock and options
             to purchase an additional 5,000,000 shares at $.08 per share
             through July 9, 1994 (the "Plata Options") and 5,000,000 shares at
             $.10 per share through July 9, 1994 (the "Additional Plata
             Options"). Pursuant to several amendments, the Plata Options and
             the Additional Plata Options are exercisable through June 30, 2000
             at an exercise price of $.15 and $.17, respectively. As of December
             31, 1999, there are outstanding Plata Options to acquire 683,300
             shares at $.15 per share and Additional Plata Options to acquire
             108,100 shares at an exercise price of $.17 per share. The fair
             value of these options are estimated to be $32,925 ($.0348 per
             option share) based upon a financial analysis of the terms of the
             options using the Black-Sholes Pricing Model with the following
             assumptions: expected volatility of 20%; risk free interest rate of
             6%. This amount has been charged to compensation expense at
             December 31, 1999 as it related to services previously provided.
             Through December 31, 1999, the Company has received approximately
             $1,332,000 pursuant to the issuance of approximately 9.2 million
             shares in connection with the exercise of the Plata Options and the
             Additional Plata Options.

         ARGENTINE AGREEMENT

             In April 1996, the Company entered into an agreement (the
             "Argentine Agreement") with DCT SRL, an Argentine corporation
             unaffiliated with the Company ("DCT") pursuant to which DCT was to
             cause a clinical trial to be conducted in two separate hospitals
             located in Buenos Aires, Argentina (the "Clinical Trials").
             Pursuant to the Argentine Agreement, the Clinical Trials were to be
             conducted pursuant to a protocol developed by Juan Carlos Flichman,
             M.D. and the purpose of the Clinical Trials was to assess the
             efficacy of the Company's drug Product R on the Human Papilloma
             Virus (HPV). The protocol calls for, among other things, a study to
             be performed with clinical and laboratory follow-up on 12 male and
             female human patients between the ages of 18 and 50.

             Pursuant to the Argentine Agreement, the Company delivered $34,000
             to DCT to cover out-of-pocket expenses associated with the Clinical
             Trials. The Argentine Agreement further provides that at the
             conclusion of the Clinical Trials, DCT shall cause Dr. Flichman to
             prepare and deliver a written report to the Company regarding the
             methodology and results of the Clinical Trials (the "Written
             Report"). In September 1996, Dr. Flichman delivered the Written
             Report to the Company. Upon delivery of the Written Report to the
             Company, the Company delivered to the principals of DCT options to
             acquire 2,000,000 shares of the Company's common stock for a period
             of one year from the date of the delivery of the Written Report, at
             a purchase price of $.20 per share. Pursuant to several amendments,
             the DCT options are exercisable through June 30, 2000 at an
             exercise price of $.21 per share. The fair value of these options
             are estimated to be $1,788 ($.0012 per option share) based

         ARGENTINE AGREEMENT (Continued)

             upon a financial analysis of the terms of the options using the
             Black-Scholes Pricing Model with the following assumptions:
             expected volatility of 20%; risk free interest rate of 6%. This
             amount has been charged to compensation expense at December 31,
             1999 as it related to services previously provided. As of December
             31, 1999, 473,500 shares of common stock were issued pursuant to
             the exercise of these options for an aggregate exercise price of
             approximately $95,000.

             In June 1994, DCT SRL and the Company entered into an exclusive
             distribution agreement whereby the Company granted to DCT, subject
             to certain conditions, the exclusive right to market and sell
             Product R in Argentina, Bolivia, Paraguay, Uruguay, Brazil, and
             Chile (the "DCT Exclusive Distribution Agreement").

             In April 1996, the Company entered into an agreement with DCT (the
             HIV-HPV Agreement") whereby the Company agreed to provide to DCT or
             its assignees, up to $600,000 to cover the costs of a double blind
             placebo controlled study in approximately 150 patients to assess
             the efficacy of Product R for the treatment of persons diagnosed
             with the HIV virus (AIDS) and HPV (the "HIV-HPV Study").
             Subsequently, the Company has agreed to advance additional funds
             towards such study.

             In connection with the HIV-HPV Agreement, the Company advanced
             approximately $665,000, which is accounted for as research and
             development expense. The amounts have been used to cover expenses
             associated with clinical activities of the HIV-HPV Study.

             The HIV-HPV Agreement provides that (i) in the event the date from
             the HIV-HPV Study is used in connection with Product R being
             approved for commercial sale anywhere within the territory granted
             under the DCT Exclusive Distribution Agreement or (ii) DCT receives
             financing to cover the costs of the HIV-HPV Study, then DCT is
             obligated to reimburse the Company for all amounts expended in
             connection with the HIV-HPV Study.

             In October 1997, the Company entered into two agreements with DCT,
             whereby the Company agreed to provide DCT or its assignees, up to
             $220,000 and $341,000 to cover the costs of double blind placebo
             controlled studies in approximately 360 and 240 patients,
             respectively to assess the efficacy of the topical application of
             Product R for the treatment of persons diagnosed with Herpes
             Labialis/Genital Infections (the "Herpes Study") and HPV (the "HPV
             Topical Study").

         ARGENTINE AGREEMENT (Continued)

             In connection with the Herpes Study and the HPV Topical Study
             (collectively, the "Studies"), the Company has advanced
             approximately $58,000 and $132,000, respectively. Such expenses are
             accounted for as research and development expense. The amounts
             expended have been used to cover expenses associated with
             pre-clinical activities. Neither the Herpes Study nor the HPV
             Topical Study has commenced.

             Both Agreements with DCT provide that (i) in the event the data
             from the Studies are used in connection with Product R being
             approved for commercial sale anywhere within the territory granted
             under the DCT Exclusive Distribution Agreement or (ii), DCT
             receives financing to cover the costs of the Studies, then DCT is
             obligated to reimburse the Company for all amounts expended in
             connection with the Studies.

             In February 1998, the Company entered into an agreement with DCT
             (the "Concurrent Agreement") whereby the Company agreed to provide
             DCT or its assignees, up to $413,000 to cover the costs of a study
             in 65 patients to compare the results of treatment of patients with
             AIDS taking a three drug cocktail and Product R with those taking a
             three drug cocktail and a placebo. As of December 31, 1999, the
             Company has advanced approximately $50,000 for such study, which
             has been accounted for as research and development expense.

             In May 1998, the Company entered into an agreement with DCT (the
             "Rheumatoid Arthritis Agreement") whereby the Company agreed to
             provide DCT or its assignees, up to $95,000 to cover the costs of a
             controlled study in 30 patients to determine the efficacy of
             Product R for the treatment of rheumatoid arthritis in humans. In
             connection with this study, the Company has advanced approximately
             $85,000, which has been accounted for as research and development
             expense.

             In July 1998, the Company authorized expenditures of up to $90,000
             to study the effects of Product R in inhibiting the mutation of the
             AIDS virus. As of December 31, 1999, the Company has advanced
             approximately $50,000 for such study, which has been accounted for
             as research and development expense.

             As of December 31, 1999, the Company advanced approximately
             $236,000 for expenses in connection with the drug approval process
             in Argentina.

         BARBADOS STUDY

             A double blind study assessing the efficacy of the Company's drug
             Product R in 43 human patients diagnosed with HIV (AIDS) has been
             conducted at the Queen Elizabeth Hospital, Bridgetown, Barbados
             (the "Barbados Study"). As of December 31, 1999, the Company has
             expended approximately $390,000 to cover the costs of the Barbados
             Study.

             In July 1998, the Company authorized expenditures of up to $45,000
             to study the effects of Product R in inhibiting the mutation of the
             AIDS virus. As of December 31, 1999, the Company has advanced
             approximately $15,000 for such study, which has been accounted for
             as research and development expense.

         NATIONAL CANCER INSTITUTE AGREEMENT

             In March 1997, the Company entered into a Material Transfer
             Agreement - Cooperative Research and Development Agreement with the
             National Cancer Institute ("NCI") of the National Institutes of
             Health. Under the terms of the Agreement, NCI researchers and the
             Company will collaborate to elucidate the molecular mechanism by
             which Product R affects the transcription of the gamma interferon
             gene. This agreement was extended for an additional one-year term
             through March 3, 1999 to investigate the anti-tumor activity of
             Product R using kidney tumor model systems. In addition, NCI was to
             study the effects of Product R on inflammation associated with
             rheumatoid arthritis.

         TOPICAL SAFETY STUDY

             During 1998, the Company paid approximately $200,000 for a safety
             study conducted in the United States for the topical use of Product
             R.

             consulting services included the development and location of
             pharmacological and biotechnology companies and assisting the
             Company in seeking joint ventures with and financing of companies
             in such industries.

         HIRSCHMAN AGREEMENT (Continued)

             In connection with the consulting agreement, the Company issued to
             Dr. Hirschman 1,000,000 shares of the Company's common stock and
             the option to acquire 5,000,000 shares of the Company's common
             stock for a period of three years as per the vesting schedule as
             referred to in the agreement, at a purchase price of $.18 per
             share. As of December 31, 1999, 900,000 shares have been issued
             upon exercise of these options for cash consideration of $162,000
             under this Agreement.

             In March 1996, the Company entered into an addendum to the
             consulting agreement with Dr. Hirschman whereby Dr. Hirschman
             agreed to provide consulting services to the Company through May
             2000 (the "Addendum"). Pursuant to the Addendum, the Company
             granted to Dr. Hirschman and his designees options to purchase an
             aggregate of 15,000,000 shares of the Company's common stock for a
             three year period pursuant to the following schedule: (i) options
             to purchase 5,000,000 shares exercisable at any time and from time
             to time commencing March 24, 1996 and ending March 23, 2009 at an
             exercise price of $.19 per share, of which options to acquire
             500,000 shares (exercisable until March 23, 2001) were assigned by
             Dr. Hirschman to Richard Rubin, consultant to Dr. Hirschman; (ii)
             options to purchase 5,000,000 shares exercisable at any time and
             from time to time commencing March 24, 1997 and ending March 23,
             2009 at an exercise price of $.27 per share, of which options to
             acquire 500,000 shares (exercisable until March 23, 2001) were
             assigned by Dr. Hirschman to Richard Rubin, consultant to Dr.
             Hirschman; and (iii) options to purchase 5,000,000 shares
             exercisable at any time and from time to time commencing March 24,
             1998 and ending March 23, 2009 at an exercise price of $.36 per
             share, of which options to acquire 500,000 shares (exercisable
             until March 23, 2001) were assigned by Dr. Hirschman to Richard
             Rubin, consultant to Dr. Hirschman. In addition, the Company has
             agreed to cause the shares underlying these options to be
             registered so long as there is no cost to the Company. As of
             December 31, 1999, 500,000 shares of common stock were issued
             pursuant to the exercise of stock options by Richard Rubin. Mr.
             Rubin has, from time to time in the past, advised the Company on
             matters unrelated to his consultation with Dr. Hirschman.

             In November 1997, Dr. Hirschman assigned to Henry Kamioner, a
             consultant to Dr. Hirschman, options to acquire 1,500,000 shares
             (500,000 at $.19, 500,000 at $.27, and 500,000 at $.36), which are
             exercisable until March 23, 2001.

             On October 14, 1996, the Company and Dr. Hirschman entered into an
             agreement (the "Employment Agreement") whereby Dr. Hirschman has
             agreed to serve as the President and Chief Executive Officer of the
             Company for a period of three years, subject to earlier termination
             by either party, either for cause as defined in and in accordance

             to $361,000 as of January 1, 2000), use of an automobile, major
             medical, term life, disability and dental insurance benefits for
             the term of his employment. The Employment Agreement further
             provides that Dr. Hirschman shall be nominated by the Company to
             serve as a member of the Company's Board of Directors and that
             Bernard Friedland and William Bregman will vote in favor of Dr.
             Hirschman as a director of the Company, for the duration of Dr.
             Hirschman's employment, and since October 1996, Dr. Hirschman has
             served as a member of the Company's Board of Directors.

             On February 18, 1998, the Board of Directors authorized a $100,000
             bonus to Dr. Hirschman and granted options to acquire 23,000,000

             In July 1998, the Company and Dr. Hirschman entered into an amended
             and restated employment agreement, which supersedes in its entirety
             the original employment agreement of October 1996. Such amendment
             and restatement extends the term of the employment agreement to
             December 31, 2000. Additionally, the February 1998 Board of
             Directors action regarding the $100,000 bonus and the granting of
             23,000,000 options (contingent upon the occurrence of certain
             events) is included in this employment agreement.

         COHEN AGREEMENTS

             In September 1992, the Company entered into a one year consulting
             agreement with Leonard Cohen (the "September 1992 Cohen
             Agreement"). The September 1992 Cohen Agreement required that Mr.
             Cohen provide certain consulting services to the Company in
             exchange for the Company's issuing to Mr. Cohen 1,000,000 shares of
             common stock (the "September 1992 Cohen Shares"), 500,000 of which
             were issuable upon execution of the September 1992 Cohen Agreement
             and the remaining 500,000 shares of which were issuable upon Mr.
             Cohen completing 50 hours of consulting service to the Company. The
             Company issued the first 500,000 shares to Mr. Cohen in October
             1992 and the remaining 500,000 shares to Mr. Cohen in February
             1993. Further pursuant to the September 1992 Cohen Agreement, the
             Company granted to Mr. Cohen the option to acquire, at any time and
             from time to time through September 10, 1993 (which date has been
             extended through June 30, 2000), the option to acquire 3,000,000

             share (which exercise price has been increased to $.16 per share)
             (the "September 1992 Cohen Options"). The fair value of these
             options are estimated to be $59,030 ($.0347 per option share) based
             upon a financial analysis of the terms of the options using the
             Black-Scholes Pricing Model with the following assumptions:
             expected volatility of 20%; risk free interest rate of 6%. This
             amount has been charged to compensation expense at December 31,
             1999 as it related to services previously provided. As of December
             31, 1999, 1,300,000 of the September 1992 Cohen Options have been
             exercised for cash consideration of $156,000.

             In February 1993, the Company entered into a second consulting
             agreement with Mr. Cohen (the "February 1993 Cohen Agreement") for
             a three year term commencing on March 1, 1993. The February 1993
             Cohen Agreement provides that Mr. Cohen provide financing business
             consulting services concerning the operations of the business of
             the Company and possible strategic transactions in exchange for the
             Company issuing to Mr. Cohen 3,500,000 shares of common stock (the
             "February 1993 Cohen Shares"), 1,500,000 shares of which Mr. Cohen
             has informed the Company he has assigned to certain other persons
             not affiliated with the Company or any of its officers or
             directors.

             The fair value of these options was estimated to be $376,126
             ($.0827 per option share) based upon a financial analysis of the
             terms of the options using the Black-Scholes Pricing Model with the
             following assumptions: expected volatility of 20%; a risk free
             interest rate of 6% and an expected holding period of three years
             (the term of the employment agreement).

             In July 1994, in consideration for services related to the
             introduction, negotiation and execution of a distribution agreement
             the Company issued: (i) to Mr. Cohen, an additional 2,500,000
             shares (the "April 1994 Cohen Shares") and (ii) to each of Elliot
             Bauer and Lee Rizzuto, 625,000 shares (the "Bauer and Rizzuto
             Shares") as well as options to acquire an additional 5,000,000
             shares each at $.10 per share exercisable through May 1, 1996 (the
             "Bauer and Rizzuto Options"). Through December 31, 1999, 2,855,000
             shares were issued pursuant to the exercise of the Bauer and
             Rizzuto Options for an aggregate exercise price of $285,500. Mr.
             Rizzuto sold all of his shares and all shares underlying his
             options. Pursuant to several amendments, the remaining Bauer
             options are exercisable through June 30, 2000 at an option price of
             $.14. The fair value of these options are estimated to be $116,101
             ($.0541 per option share) based upon a financial analysis of the
             terms of the options using the Black-Scholes Pricing Model with the
             following assumptions: expected volatility of 20%; risk free
             interest rate of 6%. This amount has been charged to compensation
             expense at December 31, 1999 as it related to services previously
             provided.

         CONSULTING AND EMPLOYMENT AGREEMENTS (Continued)

         GLOBOMAX AGREEMENT

             On January 18, 1999, the Company entered into a consulting
             agreement with Globomax LLC to provide services at hourly rates
             established by the contract to the Company's Investigational New
             Drug application submission and to perform all work that is
             necessary to obtain FDA approval. The contract was extended by
             mutual consent of both parties. The Company has incurred
             approximately $203,000 in services to GloboMax through December 31,
             1999.

         GALLANTAR AGREEMENT

             On October 1, 1999, the Company entered into an employment
             agreement with Alan Gallantar whereby Mr. Gallantar has agreed to
             serve as the Chief Financial Officer of the Company for a period of
             three years, subject to earlier termination by either party, either
             for cause as defined in and in accordance with the provisions of
             the agreement, without cause or upon the occurrence of certain
             events. Such agreement provides for Mr. Gallantar to receive a base
             salary of $175,000, $200,000 and $225,000 annually for each of the
             three years of the term of the agreement as well as various
             performance based bonuses ranging from 10% to 50% of the base
             salary and various other benefits. Additionally, in connection with
             such agreement, the Company granted Mr. Gallantar options to
             purchase an aggregate of 4,547,880 shares of the Company's common
             stock. Such options have a term of ten years and have an exercise
             price of $.24255 per share. 1,515,960 options vest on each of the
             first, second and third anniversary dates of this employment
             agreement.

             The fair value of these options are estimated to be $376,126
             ($.0827 per option share) based upon a financial analysis of the
             terms of the options using the Black-Scholes Pricing Model with the
             following assumptions: expected volatility of 20%; a risk free
             interest rate of 6% and an expected holding period of three years
             (the term of the employment agreement).

             Financial reporting of these options has been done pursuant to the
             Company's policy of following APB No. 25, and related
             interpretations, in accounting for its employee stock options.
             Accordingly, the following pro forma financial information is
             presented to reflect amortization of the fair value of the options.

         DISTRIBUTION AGREEMENTS

         The Company currently is a party to separate agreements with five
         different entities (the "Entities"), whereby the Company has granted
         exclusive rights to distribute Product R in the countries of China,
         Japan, Macao, Hong Kong, Taiwan, Mexico, Argentina, Bolivia, Paraguay,
         Uruguay, Brazil, Chile, Channel Islands, The Isle of Man, British West
         Indies, Jamaica, Haiti, Bermuda, Belize and Saudi Arabia. Pursuant to
         these agreements, distributors are obligated to cause Product R to be
         approved for commercial sale in such countries and upon such approval,
         to purchase from the Company certain minimum quantities of Product R to
         maintain the exclusive distribution rights. Leonard Cohen, a former
         consultant to the Company, has informed the Company that he is an
         affiliate of two of these entities. To date, the Company has recorded
         revenue classified as other income for the sale of territorial rights
         under the distribution agreements. The Company has made no sales under
         the distribution agreements other than for testing purposes.

         that the total expenses associated with the build-out would be
         approximately $400,000, of which $155,000 has been incurred as of
         December 31, 1999.

NOTE 11. STOCK OPTIONS

         As more fully described in Note 8 to these consolidated financial
         statements, the Company granted stock options in exchange for testing
         and consulting services. In accordance with SFAS 123, Accounting for
         Stock-Based Compensation (effective for options granted after December
         15, 1995), the Company recognized compensation cost based on the fair
         value at the grant dates. The compensation cost is amortized over the
         shorter of the service period or the life of the option. The deferred
         compensation cost is reported as a component of stockholders' equity.
         At December 31, 1999 and 1998, there were approximately 7,600,000
         option shares outstanding with a weighted average exercise price of
         $0.195 per share.

         On January 3, 2000, the Company issued to employees stock options to
         acquire an aggregate of 430,000 shares of common stock at an exercise
         price of $0.21 per share. These options expire on January 2, 2010 and
         vest in 20% increments at the end of each year for five years.

NOTE 12. SUBSEQUENT FINANCINGS

         On January 19, 2000, pursuant to the August 31, 1999 convertible
         debenture, the investors exercised their right to convert $300,000 of
         the $2,000,000 debenture outstanding into 2,178,155 shares of common
         stock.

         On January 19, 2000, pursuant to the November 1998 convertible
         debenture, the investors exercised their right to convert $1,122,500 of
         the $1,500,000 debenture outstanding into 8,252,746 shares of common
         stock.

         In addition, on January 25, 2000, pursuant to the December 28, 1999
         securities purchase agreement, the Company received an additional
         $1,000,000 structured through the convertible debenture. Therefore, the
         convertible debenture under this agreement is $2,000,000 as of January
         25, 2000.

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS


NOTE 1.  BASIS OF PRESENTATION

             The accompanying unaudited consolidated condensed financial
             statements at June 30, 2000 have been prepared in accordance with
             generally accepted accounting principles for interim financial
             information and with the instructions to Form 10-Q and reflect all
             adjustments which, in the opinion of management, are necessary for
             a fair presentation of financial position as of June 30, 2000 and
             results of operations and cash flows for the three months and the
             six months ended June 30, 2000 and 1999. All such adjustments are
             of a normal recurring nature. The results of operations for interim
             periods are not necessarily indicative of the results to be
             expected for a full year. Certain amounts in the 1999 financial
             statements have been reclassified to conform to 2000 presentation.
             The statements should be read in conjunction with the consolidated
             financial statements and footnotes thereto included in the
             Company's Annual Report on Form 10-K for the year ended December
             31, 1999.

NOTE 2.  COMMITMENTS AND CONTINGENCIES

         GOING CONCERN

             The accompanying unaudited consolidated condensed financial
             statements at June 30, 2000 have been prepared in conformity with
             generally accepted accounting principles which contemplate the
             continuance of the Company as a going concern. The Company has
             suffered losses from operations during its operating history. The
             Company is dependent upon registration of Product R for sale before
             it can begin commercial operations. The Company's cash position may
             be inadequate to pay all the costs associated with the full range
             of testing and clinical trials required by the FDA. Unless and
             until Product R is approved for sale in the United States or
             another industrially developed country, the Company may be
             dependent upon the continued sale of its securities and debt
             financing for funds to meet its cash requirements. Management
             intends to continue to sell the Company's securities in an attempt
             to mitigate the effects of its cash position; however, no assurance
             can be given that equity or debt financing, if and when required,
             will be available. In the event that such equity or debt financing
             is not available, in order to continue operations, management
             anticipates that they will have to defer their salaries. During
             2000 and 1999, the Company obtained equity and debt financing and
             may seek additional financing as the need arises. No assurance can
             be given that the Company will be able to sustain its operations
             until FDA approval is granted or that any approval will ever be
             granted. These factors raise substantial doubt about the Company's
             ability to continue as a going concern. The Company expects to
             submit an application for approval with the FDA in the near future.
             The unaudited consolidated condensed financial statements do not
             include any adjustments relating to the recoverability and
             classification of recorded assets and classification of liabilities
             that might be necessary should the Company be unable to continue in
             existence.

         POTENTIAL CLAIM FOR ROYALTIES

             The Company may be subject to claims from certain third parties for
             royalties due on the sale of Product R. The Company has not as yet
             received any notice of claim from such parties.

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                   (Continued)



NOTE 2.  COMMITMENTS AND CONTINGENCIES (Continued)

         PRODUCT LIABILITY

             The Company could be subjected to claims for adverse reactions
             resulting from the use of Product R. Although the Company is
             unaware of any such claims or threatened claims since Product R was
             initially marketed in the 1940's, one study noted adverse reactions
             from highly concentrated doses in guinea pigs. In the event any
             claims for substantial amounts were successful, they could have a
             material adverse effect on the Company's financial condition and on
             the marketability of Product R. As of the date hereof, the Company
             does not have product liability insurance for Product R. There can
             be no assurance that the Company will be able to secure such
             insurance in adequate amounts, at reasonable premiums if it
             determined to do so. Should the Company be unable to secure such
             product liability insurance, the risk of loss to the Company in the
             event of claims would be greatly increased and could have a
             material adverse effect on the Company.

         LACK OF PATENT PROTECTION

             The Company has three issued patents and one allowed patent for the
             use of Product R. The Company currently has 15 patent applications
             pending with the U.S. Patent Office and 17 foreign patent
             applications. The Company can give no assurance that other
             companies, having greater economic resources, will not be
             successful in developing a similar product. There can be no
             assurance that such patents, if obtained, will be enforceable.

         TESTING AGREEMENTS

         PLATA PARTNERS LIMITED PARTNERSHIP

             On March 20, 1992, the Company entered into an agreement with Plata
             Partners Limited Partnership ("Plata") pursuant to which Plata
             agreed to perform a demonstration in the Dominican Republic in
             accordance with a certain agreed upon protocol (the "Protocol") to
             assess the efficacy of a treatment using Product R incorporated in
             the Protocol against AIDS (the "Plata Agreement"). Plata covered
             all costs and expenses associated with the demonstration.

             Pursuant to the Plata Agreement, the Company authorized the
             issuance to Plata of 5,000,000 shares of common stock and options
             to purchase an additional 5,000,000 shares at $.08 per share
             through July 9, 1994 (the "Plata Options") and 5,000,000 shares at
             $.10 per share through July 9, 1994 (the "Additional Plata
             Options"). Pursuant to several amendments, the Plata Options and
             the Additional Plata Options were exercisable through June 30, 2000
             at an exercise price of $.15 and $.17, respectively. The fair value
             of these options are estimated to be $32,925 ($.0348 per option
             share) based upon a financial analysis of the terms of the options
             using the Black-Scholes Pricing Model with the following
             assumptions: expected volatility of 20%; risk free interest rate of
             6%. This amount has been charged to compensation expense at
             December 31, 1999 as it related to services previously provided.

         PLATA PARTNERS LIMITED PARTNERSHIP

             Through June 30, 2000, the Company has received approximately
             $1,422,000 pursuant to the issuance of approximately 9.8 million
             shares in connection with the exercise of the Plata Options and the
             Additional Plata Options.

         ARGENTINE AGREEMENT

             In April 1996, the Company entered into an agreement (the
             "Argentine Agreement") with DCT SRL, an Argentine corporation
             unaffiliated with the Company ("DCT") pursuant to which DCT was to
             cause a clinical trial to be conducted in two separate hospitals
             located in Buenos Aires, Argentina (the "Clinical Trials").
             Pursuant to the Argentine Agreement, the Clinical Trials were to be
             conducted pursuant to a protocol developed by Juan Carlos Flichman,
             M.D. and the purpose of the Clinical Trials was to assess the
             efficacy of the Company's drug, Product R, on the Human Papilloma
             Virus (HPV). The protocol calls for, among other things, a study to
             be performed with clinical and laboratory follow-up on 12 male and
             female human patients between the ages of 18 and 50.

             Pursuant to the Argentine Agreement, the Company delivered $34,000
             to DCT to cover out-of-pocket expenses associated with the Clinical
             Trials. The Argentine Agreement further provides that at the
             conclusion of the Clinical Trials, DCT shall cause Dr. Flichman to
             prepare and deliver a written report to the Company regarding the
             methodology and results of the Clinical Trials (the "Written
             Report"). In September 1996, the Written Report was delivered by
             Dr. Flichman to the Company. Upon delivery of the Written Report to
             the Company, the Company delivered to the principals of DCT options
             to acquire 2,000,000 shares of the Company's common stock for a
             period of one year from the date of the delivery of the Written
             Report, at a purchase price of $.20 per share. Pursuant to several
             amendments, the DCT options were exercisable through June 30, 2000
             at an exercise price of $.21 per share. Effective July 1, 2000,
             these options were extended to December 31, 2000 at an exercise
             price of $.22 per share. The fair value of these options are
             estimated to be $1,788 ($.0012 per option share) based on the
             following assumptions: expected volatility of 20%; risk free
             interest rate of 6%. This amount has been charged to compensation
             expense at December 31, 1999 as it related to services previously
             provided. As of June 30, 2000, 1,266,000 shares of common stock
             were issued pursuant to the exercise of these options for an
             aggregate exercise price of approximately $261,425.

             In June 1994, DCT SRL and the Company entered into an exclusive
             distribution agreement whereby the Company granted to DCT, subject
             to certain conditions, the exclusive right to market and sell
             Product R in Argentina, Bolivia, Paraguay, Uruguay, Brazil, and
             Chile (the "DCT Exclusive Distribution Agreement").

         ARGENTINE AGREEMENT (Continued)

             In April 1996, the Company entered into an agreement with DCT (the
             HIV-HPV Agreement") whereby the Company agreed to provide to DCT or
             its assignees, up to $600,000 to cover the costs of a double blind
             placebo controlled study in approximately 150 patients to assess
             the efficacy of Product R for the treatment of persons diagnosed
             with the HIV virus (AIDS) and HPV (the "HIV-HPV Study").
             Subsequently, the Company has agreed to advance additional funds
             towards such study. In connection with the HIV-HPV Agreement, the
             Company advanced approximately $665,000 which is accounted for as
             research and development expense. The amounts have been used to
             cover expenses associated with clinical activities of the HIV-HPV
             Study.

             The HIV-HPV Agreement provides that (i) in the event the date from
             the HIV-HPV Study is used in connection with Product R being
             approved for commercial sale anywhere within the territory granted
             under the DCT Exclusive Distribution Agreement or (ii) DCT receives
             financing to cover the costs of the HIV-HPV Study, then DCT is
             obligated to reimburse the Company for all amounts expended in
             connection with the HIV-HPV Study.

             In October 1997, the Company entered into two agreements with DCT,
             whereby the Company agreed to provide DCT or its assignees, up to
             $220,000 and $341,000 to cover the costs of double blind placebo
             controlled studies in approximately 360 and 240 patients,
             respectively to assess the efficacy of the topical application of
             Product R for the treatment of persons diagnosed with Herpes
             Labialis/Genital Infections (the "Herpes Study") and HPV (the "HPV
             Topical Study").

             In connection with the Herpes Study and the HPV Topical Study
             (collectively, the "Studies"), the Company has advanced
             approximately $58,000 and $132,000, respectively. Such expenses are
             accounted for as research and development expense. The amounts
             expended have been used to cover expenses associated with
             pre-clinical activities. Neither the Herpes Study nor the HPV
             Topical Study has commenced.

             Both Agreements with DCT provide that (i) in the event the data
             from the Studies are used in connection with Product R being
             approved for commercial sale anywhere within the territory granted
             under the DCT Exclusive Distribution Agreement or (ii), DCT
             receives financing to cover the costs of the Studies, then DCT is
             obligated to reimburse the Company for all amounts expended in
             connection with the Studies.

             In February 1998, the Company entered into an agreement with DCT
             (the "Concurrent Agreement") whereby the Company agreed to provide
             DCT or its assignees, up to $413,000 to cover the costs of a study
             in 65 patients to compare the results of treatment of patients with
             AIDS taking a three drug cocktail and Product R with those taking a
             three drug cocktail and a

             placebo. As of June 30, 2000, the Company has advanced
             approximately $50,000 for such study which has been accounted for
             as research and development expense.

             In May 1998, the Company entered into an agreement with DCT (the
             "Rheumatoid Arthritis Agreement") whereby the Company agreed to
             provide DCT or its assignees, up to $95,000 to cover the costs of a
             controlled study in 30 patients to determine the efficacy of
             Product R for the treatment of rheumatoid arthritis in humans. In
             connection with this study, the Company has advanced approximately

         HIRSCHMAN AGREEMENT (Continued)

             In connection with the consulting agreement, the Company issued to
             Dr. Hirschman 1,000,000 shares of the Company's common stock and
             the option to acquire 5,000,000 shares of the Company's common
             stock for a period of three years per the vesting schedule as
             referred to in the agreement, at a purchase price of $.18 per
             share. As of June 30, 2000, 900,000 shares have been issued upon
             exercise of these options for cash consideration of $162,000 under
             this Agreement.

             In March 1996, the Company entered into an addendum to the
             consulting agreement with Dr. Hirschman whereby Dr. Hirschman
             agreed to provide consulting services to the Company through May
             2000 (the "Addendum"). Pursuant to the Addendum, the Company
             granted to Dr. Hirschman and his designees options to purchase an
             aggregate of 15,000,000 shares of the Company's common stock for a
             three year period pursuant to the following schedule: (i) options
             to purchase 5,000,000 shares exercisable at any time and from time
             to time commencing March 24, 1996 and ending March 23, 2009 at an
             exercise price of $.19 per share, of which options to acquire
             500,000 shares (exercisable until March 23, 2001) were assigned by
             Dr. Hirschman to Richard Rubin, consultant to Dr. Hirschman; (ii)
             options to purchase 5,000,000 shares exercisable at any time and
             from time to time commencing March 24, 1997 and ending March 23,
             2009 at an exercise price of $.27 per share, of which options to
             acquire 500,000 shares (exercisable until March 23, 2001) were
             assigned by Dr. Hirschman to Richard Rubin, consultant to Dr.
             Hirschman; and (iii) options to purchase 5,000,000 shares
             exercisable at any time and from time to time commencing March 24,
             1998 and ending March 23, 2009 at an exercise price of $.36 per
             share, of which options to acquire 500,000 shares (exercisable
             until March 23, 2001) were assigned by Dr. Hirschman to Richard
             Rubin, consultant to Dr. Hirschman. In addition, the Company has
             agreed to cause the shares underlying these options to be
             registered so long as there is no cost to the Company. As of June
             30, 2000, 663,000 shares of common stock were issued pursuant to
             the exercise of stock options by Richard Rubin. Mr. Rubin has, from
             time to time in the past, advised the Company on matters unrelated
             to his consultation with Dr. Hirschman.

             In March 2000, Mr. Rubin transferred 75,000 of his $0.27 options
             and 75,000 of his $0.36 options to Elliot Bauer, an individual who
             also received and exercised shares and options as a result of the
             "Cohen Agreements".

             In November 1997, Dr. Hirschman assigned to Henry Kamioner, a
             consultant to Dr. Hirschman, options to acquire 1,500,000 shares
             (500,000 at $.19, 500,000 at $.27, and 500,000 at $.36), which are
             exercisable until March 23, 2001.

             In May 2000, the Company and Dr. Hirschman entered into a second
             amended and restated employment agreement (the "Agreement") which
             supersedes in its entirety the July 1988 Employment Agreement.

         CONSULTING AND EMPLOYMENT AGREEMENTS (Continued)

         HIRSCHMAN AGREEMENT (Continued)

             Pursuant to this Agreement, Dr. Hirschman is employed to serve as
             Chief Executive Officer and President of the Company until December
             31, 2002. The Agreement further provides that Bernard Friedland and
             William Bregman will vote all shares owned or voted by them in
             favor of Dr. Hirschman as a member of the Board of Directors of the
             Company.

             The Agreement provides for Dr. Hirschman to receive an annual base
             salary of $361,000 (effective January 1, 2000), use of an
             automobile, major medical, disability, dental and term life
             insurance benefits for the term of his employment.

             The Agreement also provides for previously issued options to
             acquire 23,000,000 shares of common stock at $0.27 per option share
             to be immediately vested as of the date of this agreement.

             The fair value of these options are estimated to be $5,328,441
             ($0.2317 per option share) based upon a financial analysis of the
             terms of the options using the Black-Scholes Pricing Model with the
             following assumptions: expected volatility of 80%; a risk free
             interest rate of 6% and an expected holding period of 32 months
             (the term of the employment agreement).

         GALLANTAR AGREEMENT

             On October 1, 1999, the Company entered into an employment
             agreement with Alan Gallantar whereby Mr. Gallantar has agreed to
             serve as the Chief Financial Officer of the Company for a period of
             three years, subject to earlier termination by either party, either
             for cause as defined in and in accordance with the provisions of
             the agreement, without cause or upon the occurrence of certain
             events. Such agreement provides for Mr. Gallantar to receive a base
             salary of $175,000, $200,000 and $225,000 annually for each of the
             three years of the term of the agreement as well as various
             performance based bonuses ranging from 10% to 50% of the base
             salary and various other benefits. Additionally, in connection with
             such agreement, the Company granted Mr. Gallantar options to
             purchase an aggregate of 4,547,880 shares of the Company's common
             stock. Such options have a term of ten years and have an exercise
             price of $.24255 per share. 1,515,960 options vest on each of the
             first, second and third anniversary dates of this employment
             agreement.

             The fair value of these options are estimated to be $376,126
             ($.0827 per option share) based upon a financial analysis of the
             terms of the options using the Black-Scholes Pricing Model with the
             following assumptions: expected volatility of 20%; a risk free
             interest rate of 6% and an expected holding period of three years
             (the term of the employment agreement).

         COHEN AGREEMENTS

             In September 1992, the Company entered into a one year consulting
             agreement with Leonard Cohen (the "September 1992 Cohen
             Agreement"). The September 1992 Cohen Agreement required that Mr.
             Cohen provide certain consulting services to the Company in
             exchange for the Company's issuing to Mr. Cohen 1,000,000 shares of
             common stock (the "September 1992 Cohen Shares"), 500,000 of which
             were issuable upon execution of the September 1992 Cohen Agreement
             and the remaining 500,000 shares of which were issuable upon Mr.
             Cohen completing 50 hours of consulting service to the Company. The
             Company issued the first 500,000 shares to Mr. Cohen in October
             1992 and the remaining 500,000 shares to Mr. Cohen in February
             1993. Further pursuant to the September 1992 Cohen Agreement, the
             Company granted to Mr. Cohen the option to acquire, at any time and
             from time to time through September 10, 1993 (which date has been
             extended through June 30, 2000), the option to acquire 3,000,000
             shares of common stock of the Company at an exercise price of $.09
             per share (which exercise price has been increased to $.16 per
             share) (the "September 1992 Cohen Options"). Effective July 1,
             2000, these options were extended to December 31, 2000 at an
             exercise price of $.17 per share. The fair value of these options
             are estimated to be $59,030 ($.0347 per option share) based upon a
             financial analysis of the terms of the options using the
             Black-Scholes Pricing Model with the following assumptions:
             expected volatility of 20%; risk free interest rate of 6%. This
             amount has been charged to compensation expense at December 31,
             1999 as it related to services previously provided. As of June 30,
             2000, 2,800,000 of the September 1992 Cohen Options have been
             exercised for cash consideration of $386,000.

         CONSULTING AND EMPLOYMENT AGREEMENTS (Continued)

         COHEN AGREEMENTS (Continued)

             In February 1993, the Company entered into a second consulting
             agreement with Mr. Cohen (the "February 1993 Cohen Agreement") for
             a three year term commencing on March 1, 1993. The February 1993
             Cohen Agreement provides that Mr. Cohen provide financing business
             consulting services concerning the operations of the business of
             the Company and possible strategic transactions in exchange for the
             Company issuing to Mr. Cohen 3,500,000 shares of common stock (the
             "February 1993 Cohen Shares"), 1,500,000 shares of which Mr. Cohen
             has informed the Company he has assigned to certain other persons
             not affiliated with the Company or any of its officers or
             directors.

             In July 1994, in consideration for services related to the
             introduction, negotiation and execution of a distribution agreement
             the Company issued: (i) to Mr. Cohen, an additional 2,500,000
             shares (the "April 1994 Cohen Shares") and (ii) to each of Elliot
             Bauer and Lee Rizzuto, 625,000 shares (the "Bauer and Rizzuto
             Shares") as well as options to acquire an additional 5,000,000
             shares each at $.10 per share exercisable through May 1, 1996 (the
             "Bauer and Rizzuto Options"). Through March 31, 2000, 3,455,000
             shares were issued pursuant to the exercise of the Bauer and
             Rizzuto Options for an aggregate exercise price of $240,000. Mr.
             Rizzuto sold all of his shares and all shares underlying his
             options. Pursuant to several amendments, the remaining Bauer
             options are exercisable through June 30, 2000 at an option price of
             $.14. Effective July 1, 2000, these options have been extended to
             December 31, 2000 at an exercise price of $.16 per share. The fair
             value of these options are estimated to be $116,101 ($.0541 per
             option share) based upon a financial analysis of the terms of the
             options using the Black-Scholes Pricing Model with the following
             assumptions: expected volatility of 20%; risk free interest rate of
             6%. This amount has been charged to compensation expense at
             December 31, 1999 as it related to services previously provided.

         GLOBOMAX AGREEMENT

             On January 18, 1999, the Company entered into a consulting
             agreement with GloboMax LLC to provide services at hourly rates
             established by the contract to the Company's Investigational New
             Drug application submission and to perform all work that is
             necessary to obtain FDA approval. The contract was extended
             indefinitely by mutual consent of both parties. The Company has
             incurred approximately $577,000 in services to GloboMax through
             June 30, 2000.

         HARBOR VIEW AGREEMENT

             On February 7, 2000, the Company entered into a consulting
             agreement with Harbor View Group, Inc. for past and future
             consulting services related to corporate structures, financial
             transactions, financial public relations and other matters through
             December 31, 2000.

         CONSULTING AND EMPLOYMENT AGREEMENTS (Continued)

         HARBOR VIEW AGREEMENT (Continued)

             In connection with this agreement, the Company issued warrants to
             purchase 1,750,000 shares at an exercise price of $0.21 per share
             and warrants to purchase 1,750,000 shares at an exercise price of
             $0.26 per share until February 28, 2005. The fair value of the
             warrants is estimated to be $200,249 ($.057 per warrant) based upon
             a financial analysis of the terms of the warrants using the
             Black-Scholes Pricing Model with the following assumptions:
             expected volatility of 90%; a risk free interest rate of 6% and an
             expected holding period of eleven months (the term of the
             consulting agreement).

             The Company has determined that $89,045 of the fair value relates
             to past services and, accordingly, has expensed this portion in the
             three months ended March 31, 2000. The remaining $111,204 is
             included in other current assets and is being amortized over the
             remaining term of the agreement.

         DISTRIBUTION AGREEMENTS

         The Company currently is a party to separate agreements with five
         different entities (the "Entities"), whereby the Company has granted
         exclusive rights to distribute Product R in the countries of China,
         Japan, Macao, Hong Kong, Taiwan, Mexico, Argentina, Bolivia, Paraguay,
         Uruguay, Brazil, Chile, Channel Islands, The Isle of Man, British West
         Indies, Jamaica, Haiti, Bermuda, Belize and Saudi Arabia. Pursuant to
         these agreements, distributors are obligated to cause Product R to be
         approved for commercial sale in such countries and upon such approval,
         to purchase from the Company certain minimum quantities of Product R to
         maintain the exclusive distribution rights. Leonard Cohen, a former
         consultant to the Company, has informed the Company that he is an
         affiliate of two of these entities. To date, the Company has recorded
         revenue classified as other income for the sale of territorial rights
         under the distribution agreements. The Company has made no sales under
         the distribution agreements other than for testing purposes.

         OTHER

         The Company has entered into an agreement with an unaffiliated third
         party to increase the square footage of its corporate and laboratory
         facilities in Yonkers, New York (the "build-out"). The total expenses
         associated with the build-out of approximately $400,000, have been
         incurred as of June 30, 2000.

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                   (Continued)


NOTE 3.  CONVERTIBLE DEBENTURES

         In February 1997 and October 1997, in order to finance research and
         development, the Company sold $1,000,000 and $3,000,000, respectively,
         principal amount of its ten-year 7% Convertible Debentures (the
         "February Debenture" and the "October Debenture", collectively, the
         "Debentures") due February 28, 2007 and August 30, 2007, respectively,
         to RBB Bank Aktiengesellschaft ("RBB") in offshore transactions
         pursuant to Regulation S under the Securities Act of 1933, as amended.
         Accrued interest under the Debentures was payable semi-annually,
         computed at the rate of 7% per annum on the unpaid principal balance
         from the date of issuance until the date of interest payment. The
         Debentures were convertible, at the option of the holder, into shares
         of Common Stock pursuant to specified formulas. On April 22, 1997, June
         6, 1997, July 3, 1997 and August 20, 1997, pursuant to notice by the
         holder, RBB, to the Company under the February Debenture, $330,000,
         $134,000, $270,000 and $266,000, respectively, of the principal amount
         of the February Debenture was converted into 1,648,352, 894,526,
         2,323,580 and 1,809,524 shares of the Common Stock, respectively. As of
         August 20, 1997, the February Debenture was fully converted. On
         December 9, 1997, January 7, 1998, January 14, 1998, February 19, 1998,
         February 23, 1998, March 31, 1998, May 4, 1998 and May 5, 1998,
         pursuant to notice by the holder, RBB, to the Company, $120,000,
         $133,000, $341,250, $750,000, $335,750, $425,000, $275,000 and
         $620,000, respectively, of the October Debenture was converted into
         772,201, 1,017,011, 2,512,887, 5,114,218, 1,498,884, 1,870,869,
         1,491,485 and 3,299,979 Common Stock, respectively. As of May 5, 1998,
         the October Debenture was fully converted.

         In connection with the issuance of the February Debenture, the Company
         issued to RBB three warrants (the "February Warrants") to purchase
         common stock, each such February Warrant entitling the holder to
         purchase, from February 21, 1997 through February 28, 2007, 178,378
         shares of common stock. The exercise price of the three February
         Warrants are $0.288, $0.576 and $0.864 per warrant share, respectively.
         The fair value of the February Warrants was estimated to be $37,000
         ($.021 per warrant) based upon a financial analysis of the terms of the
         warrants using the Black-Scholes Pricing Model. This amount has been
         reflected in the accompanying financial statements as interest expense
         related to the convertible February Debenture. Based on the terms for
         conversion associated with the February Debenture, there was an
         intrinsic value associated with the beneficial conversion feature of
         $413,793. This amount has been fully amortized to interest expense with
         a corresponding credit to additional paid-in capital.

         In connection with the issuance of the October Debenture, the Company
         issued to RBB three warrants (the "October Warrants") to purchase
         Common Stock, each such October Warrant entitling the holder to
         purchase, from the date of grant through August 30, 2007, 600,000
         shares of the Common Stock. The exercise price of the three October
         Warrants are $0.20, $0.23 and $0.27 per warrant share, respectively.
         The fair value of the three October Warrants was established to be
         $106,571 ($.178 per warrant), $97,912 ($.163 per warrant) and $87,472
         ($.146 per warrant), respectively, based upon a financial analysis of
         the terms of the warrants using the Black-Scholes Pricing Model. This
         amount has been reflected in the accompanying financial statements as a
         discount on the convertible debenture, with a corresponding credit to
         additional paid-in capital, and is being amortized over the expected
         term of the notes, which at December 31, 1997 was 120 months. In May
         1998, the remaining unamortized discount of $276,957 was amortized upon
         full conversion of the October Debenture.

NOTE 3.  CONVERTIBLE DEBENTURES (Continued)

         Based on the terms for conversion associated with the October
         Debenture, there was an intrinsic value associated with the beneficial
         conversion feature of $1,350,000. This amount was treated as deferred
         interest expense and recorded as a reduction of the convertible
         debenture liability with a corresponding credit to additional paid-in
         capital and has been amortized to interest expense over the period from
         October 8, 1997 (date of debenture) to February 24, 1998 (date the
         debenture is fully convertible). The interest expense relative to this
         item was $210,951 for 1998 and $1,139,049 for 1997.

         In November 1998, in order to finance further research and development,
         the Company sold 1,500,000 principal amount of its ten year 7%
         Convertible Debenture (the "November Debenture") due October 31, 2008,
         to RBB. Accrued interest under the November Debenture is payable
         semi-annually, computed at the rate of 7% per annum on the unpaid
         principal balance from the date of the issuance of the November
         Debenture until the date of interest payment. The November Debenture
         may be prepaid by the Company before maturity, in whole or in part,
         without premium or penalty, if the Company gives the holder of the
         Debenture notice not less than 30 days before the date fixed for
         prepayment in that notice. The November Debenture is convertible, at
         the option of the holder, into shares of common stock.

         On January 19, 2000 and March 7, 2000 pursuant to notice by the holder,
         RBB, to the Company under the November Debenture, $1,122,500 and
         $377,500, respectively, of the principal amount of the November
         Debenture was converted into 8,252,746 and 1,887,500 shares of the
         common stock, respectively. As of March 7, 2000, the November Debenture
         was fully converted.

         In connection with the issuance of the November Debenture, the Company
         issued to RBB two warrants (the "November Warrants") to purchase Common
         Stock, each such November Warrant entitling the holder to purchase
         375,000 shares of the Common Stock at any time and from time to time
         through October 31, 2008. The exercise price of the two November
         Warrants are $.20 and $.24 per warrant share, respectively. The fair
         value of the November warrants was estimated to be $48,000 ($.064 per
         warrant) based upon a financial analysis of the terms of the warrants
         using the Black-Scholes Pricing Model with the following assumptions:
         expected volatility of 20%; a risk free interest rate of 5.75% and an
         expected holding period of one year. This amount has been amortized to
         interest expense in the accompanying consolidated condensed financial
         statements.

         Based on the terms for conversion associated with the November
         Debenture, there was an intrinsic value associated with the beneficial
         conversion feature of $625,000. This amount was recorded as interest
         expense in 1998.

         In August 1999, in order to finance further research and development,
         the Company entered into a securities purchase agreement to issue an
         aggregate of 20 units, each unit consisting of $100,000 principal
         amount of the Company's 7% convertible debenture (the "August
         Debenture") due August 3, 2009 to Focus Investors LLC ("Focus").
         Accrued interest under the August Debenture is payable semi-annually,
         computed at the rate of 7% on the unpaid principal balance from the
         date of issuance until the date of the interest payment. No payment of

NOTE 3.  CONVERTIBLE DEBENTURES (Continued)

         principal of the August Debenture may be made prior to the maturity
         date without the consent of the holder. The August Debenture is
         convertible, at the option of the holder, into shares of common stock.
         On January 19, 2000, February 17, 2000 and March 3, 2000 pursuant to
         notice by the holder, Focus, to the Company under the August Debenture,
         $300,000, $900,000 and $800,000, respectively, of the principal amount
         of the August Debenture was converted into 2,178,155, 6,440,735 and
         5,729,967 shares of the common stock, respectively. As of March 3, 2000
         the November Debenture was fully converted.

         In connection with the issuance of the August Debenture, the Company
         issued to Focus one warrant (the "August Warrant") to purchase Common
         Stock, such August Warrant entitling the holder to purchase 1,000,000
         shares of the Common Stock at any time and from time to time through
         August 3, 2004. The exercise price of the August Warrant is $.2461 per
         warrant share. The fair value of the August Warrants was estimated to
         be $52,593 ($.0526 per warrant share) based upon a financial analysis
         of the terms of the warrant using the Black-Scholes Pricing Model with
         the following assumptions: expected volatility of 20%; a risk free
         interest rate of 5.75% and an expected holding period of five years.
         This amount has been amortized to interest expense in the accompanying
         consolidated condensed financial statements.

         Based on the terms for conversion associated with the August Debenture,
         there was an intrinsic value associated with the beneficial conversion
         feature of $687,500. This amount was recorded as interest expense in
         1999.

         In December 1999, in order to finance further research and development,
         the Company entered into a securities purchase agreement to sell
         $2,000,000 principal amount of the Company's 7% convertible debenture
         (the December Debenture) due December 28, 2009 to Endeavour Capital
         ("Endeavour"). Accrued interest under the December Debenture is payable
         semi-annually, computed at the rate of 7% on the unpaid principal
         balance from the date of issuance until the date of the interest
         payment. No payment of the principal of the December Debenture may be
         made prior to the maturity date without the consent of the holder. The
         December Debenture is convertible, at the option of the holder, into
         shares of common stock.

         During 1999, $1,000,000 of these debentures were sold. The remaining
         $1,000,000 was not available until the shares underlying the first
         $1,000,000 were registered. Such registration statement was declared
         effective in January 2000 and the remaining $1,000,000 transaction was
         consummated.

         On January 27, 2000, February 22, 2000, February 23, 2000, February 24,
         2000 and February 29, 2000 pursuant to notice by the holder, Endeavour,
         to the Company under the December Debenture, $150,000, $135,000,
         $715,000, $785,000 and $200,000, respectively, of the principal amount
         of the December Debenture was converted into 1,105,435, 988,913,
         5,149,035, 5,622,696 and 1,036,674 shares of the common stock,
         respectively. As of June 30, 2000, $15,000 of the December Debenture
         remained outstanding.

NOTE 3.  CONVERTIBLE DEBENTURES (Continued)

         In connection with the issuance of the first $1,000,000 of the December
         Debenture, the Company issued to Endeavour warrants (the December
         Warrants) to purchase Common Stock, such December Warrant entitling the
         holder to purchase 100,000 shares of the Common Stock at any time and
         from time to time through December 31, 2002. The exercise price of the
         December Warrant is $.19 per warrant share. The fair value of the
         December Warrants was estimated to be $4,285 ($.0429 per warrant share)
         based upon a financial analysis of the terms of the warrant using the
         Black-Scholes Pricing Model with the following assumptions: expected
         volatility of 20%; a risk free interest rate of 6% and an expected
         holding period of three years. This amount has been amortized to
         interest expense in the accompanying consolidated financial statements.

         Based on the terms for conversion associated with the first $1,000,000
         of the December Debenture, there was an intrinsic value associated with
         the beneficial conversion feature of $357,143. This amount has been
         recorded as interest expense in 1999.

         In connection with the issuance of the second $1,000,000 of the
         December Debenture, the Company issued to Endeavour warrants (the
         December Warrants) to purchase Common Stock, such December Warrant
         entitling the holder to purchase 100,000 shares of the Common Stock at
         any time and from time to time through December 31, 2002. The exercise
         price of the December Warrant is $.20 per warrant share. The fair value
         of the December Warrants was estimated to be $13,600 ($.136 per warrant
         share) based upon a financial analysis of the terms of the warrant
         using the Black-Scholes Pricing Model with the following assumptions:
         expected volatility of 90%; a risk free interest rate of 6% and an
         expected holding period of three years. This amount has been amortized
         to interest expense in the accompanying consolidated financial
         statements.

         Based on the terms for conversion associated with the second $1,000,000
         of the December Debenture, there was an intrinsic value associated with
         the beneficial conversion feature of $386,909. This amount has been
         recorded as interest expense in 2000.

NOTE 4.  SECURITIES PURCHASE AGREEMENTS

         In January 1999, pursuant to a securities purchase agreement, the
         Company issued 4,917,276 shares of its common stock for an aggregate
         purchase price of $802,500. Such agreement also provided for the
         issuance of four warrants to purchase a total of 2,366,788 shares of
         common stock at prices ranging from $.204 to $.2448 per share at any
         time until December 31, 2003. The fair value of these warrants was
         estimated to be $494,138 ($.209 per warrant) based upon a financial
         analysis of the terms of the warrants using the Black-Scholes Pricing
         Model with the following assumptions: expected volatility of 20%; a
         risk free interest rate of 6% and an expected holding period of five
         years. This amount is being amortized to interest expense in the
         accompanying consolidated financial statements.

         On June 23, 1999, the Company entered into a securities purchase
         agreement with certain individuals whereby the Company will issue
         1,851,852 shares of its common stock for an aggregate purchase price of
         $500,000. These proceeds were received in July 1999. Such agreement
         also provides for the issuance of warrants to purchase an aggregate of
         925,926 shares of common stock at any time until June 30, 2004. The
         fair value of these warrants was estimated to be $37,000 ($.04 per
         warrant) based upon a financial analysis of the terms of the warrants
         using the Black-Scholes Pricing Model with the following assumptions:
         expected volatility of 20%; a risk free interest rate of 5.75% and an
         expected holding period of five years. This amount is being amortized
         to interest expense in the accompanying consolidated financial
         statements.

         Pursuant to a securities purchase agreement with Harbor View Group and
         other various purchasers, dated February 16, 2000, the Company received
         $3,000,000 on March 9, 2000 in exchange for 13,636,357 shares of common
         stock.

         Additionally, in connection with the above described securities
         purchase agreement, the Company issued warrants to purchase an
         aggregate of 5,454,544 shares of common stock. Fifty percent (50%) of
         the warrants are exercisable at $0.275 per share and fifty percent
         (50%) of the warrants are exercisable at $0.33 per share, until
         February 28, 2005. The fair value of these warrants was estimated to be
         $1,582,734 ($0.295 and $0.285 per warrant share) based upon a financial
         analysis of the terms of the warrant using the Black-Scholes Pricing
         Model with the following assumptions; expected volatility of 90%; a
         risk free interest rate of 6% and an expected holding period of five
         years. This amount is being amortized to interest expense in the
         accompanying consolidated condensed financial statements.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Article Ninth of our Certificate of Incorporation contains the
following provision with respect to indemnification of directors and officers:

         Ninth: The Corporation shall, to the fullest extent permitted by
         Section 145 of the General Corporation Law of the State of Delaware, as
         the same may be amended and supplemented, indemnify any and all persons
         whom it shall have power to indemnify under said section from and
         against any and all of the expenses, liabilities or other matters
         referred to in or covered by said section, and the indemnification
         provided for herein shall not be deemed exclusive of any other rights
         to which those indemnified may be entitled under any By-law, agreement,
         vote of stockholders or disinterested directors or otherwise, both as
         to action in his official capacity and as to action in another capacity
         while holding such office, and shall continue as to a person, who has
         ceased to be director, officer, employee or agent and shall inure to
         the benefit of the heirs, executors and administrators of such a
         person.

         Section 145 of the General Corporate Law of the State of Delaware (the
"DGCL") contains provisions regarding indemnification, among others, of officers
and directors. Section 145 of the DGCL provides in relevant part:

                  (a) A corporation shall have power to indemnify any person who
         was or is a party or is threatened to be made a party to any
         threatened, pending or completed action, suit or proceeding, whether
         civil, criminal, administrative or investigative (other than an action
         by or in the right of the corporation) by reason of the fact that the
         person is or was a director, officer, employee or agent of the
         corporation, or is or was serving at the request of the corporation as
         a director, officer, employee or agent of another corporation,
         partnership, joint venture, trust or other enterprise, against expenses
         (including attorneys' fees), judgments, fines and amounts paid in
         settlement actually and reasonably incurred by the person in connection
         with such action, suit or proceeding if the person acted in good faith
         and in a manner the person reasonably believed to be in or not opposed
         to the best interests of the corporation, and, with respect to any
         criminal action or proceeding, had no reasonable cause to believe the
         person's conduct was unlawful. The termination of any action, suit or
         proceeding by judgment, order, settlement, conviction, or upon a plea
         of nolo contendere or its equivalent, shall not, of itself, create a
         presumption that the person did not act in good faith and in a manner
         which the person reasonably believed to be in or not opposed to the
         best interests of the corporation, and, with respect to any criminal
         action or proceeding, had reasonable cause to believe that the person's
         conduct was unlawful.

                  (b) A corporation shall have power to indemnify any person who
         was or is a party or is threatened to be made a party to any
         threatened, pending or completed action or suit by or in the right of
         the corporation to procure a judgment in its favor by reason of the




                                      II-1
<PAGE>   117



         fact that the person is or was a director, officer, employee or agent
         of the corporation, or is or was serving at the request of the
         corporation as a director, officer, employee or agent of another
         corporation, partnership, joint venture, trust or other enterprise
         against expenses (including attorneys' fees) actually and reasonably
         incurred by the person in connection with the defense or settlement of
         such action or suit if the person acted in good faith and in a manner
         the person reasonably believed to be in or not opposed to the best
         interests of the corporation and except that no indemnification shall
         be made in respect of any claim, issue or matter as to which such
         person shall have been adjudged to be liable to the corporation unless
         and only to the extent that the Court of Chancery or the court in which
         such action or suit was brought shall determine upon application that,
         despite the adjudication of liability but in view of all the
         circumstances of the case, such person is fairly and reasonably
         entitled to indemnity for such expenses which the Court of Chancery or
         such other court shall deem proper.

                  (c) To the extent that a present or former director or officer
         of a corporation has been successful on the merits or otherwise in
         defense of any action, suit or proceeding referred to in subsections
         (a) and (b) of this section, or in defense of any claim, issue or
         matter therein, such person shall be indemnified against expenses
         (including attorneys' fees) actually and reasonably incurred by such
         person in connection therewith.

                  (d) Any indemnification under subsections (a) and (b) of this
         section (unless ordered by a court) shall be made by the corporation
         only as authorized in the specific case upon a determination that
         indemnification of the present or former director, officer, employee or
         agent is proper in the circumstances because the person has met the
         applicable standard of conduct set forth in subsections (a) and (b) of
         this section. Such determination shall be made, with respect to a
         person who is a director or officer at the time of such determination,
         (1) by a majority vote of the directors who are not parties to such
         action, suit or proceeding, even though less than a quorum, or (2) by a
         committee of such directors designated by majority vote of such
         directors, even though less than a quorum, or (3) if there are no such
         directors, or if such directors so direct, by independent legal counsel
         in a written opinion, or (4) by the stockholders.

         Delaware law also permits a corporation to purchase and maintain
insurance on behalf of any person who is or was a director or officer against
any liability asserted against him and incurred by him in such capacity or
arising out of his status as such, whether or not the corporation has the power
to indemnify him against that liability under Section 145 of the DGCL.

         Our Certificate of Incorporation was amended on December 30, 1987, to
limit or eliminate director liability by incorporating new Article Eleventh,
which provides:

         A director of the Corporation shall not be personally liable to the
         Corporation or its stockholders for monetary damages for breach of
         fiduciary duty as a director, except for liability (i) for any breach
         of the director's duty of loyalty to the Corporation or its
         stockholders, (ii) for acts or omissions not in good faith or which
         involve intentional misconduct or a knowing violation of laws, (iii)
         under Section 174 of the Delaware General Corporation Law, or (iv) for
         any transaction from which the director derived an improper personal
         benefit.

         The above discussion of our Certificate of Incorporation is not
intended to be exhaustive and is respectively qualified in its entirety by such
document.

ITEM 17. UNDERTAKINGS

         The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

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

                  (ii) To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of



                                     II-10
<PAGE>   126



securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20 percent change in the
maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement.

                  (iii) To include any material with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

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

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provision described under Item 20 or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. If a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
