         ADVR cautions readers that some of the information in this report
contains forward-looking statements within the meaning of the federal securities
laws. For this purpose, any statements contained in this report that are not
statements of historical fact may be deemed to be forward- looking statements.
Forward-looking statements typically are identified by use of terms like "may,"
"will," "expect," "anticipate," "estimate", "believe", "intend", "could",
"would" and similar words, although some forward-looking statements are
expressed differently. You should be aware that ADVR's actual results could
differ materially from those contained in the forward-looking statements due to
a number of factors, including our limited operating history and substantial
operating losses, availability of capital resources, ability to effectively
compete, economic conditions, unanticipated difficulties in pharmaceutical
research and development, ability to continue research and development, ability
to gain governmental approvals, uncertainty relating to timing of governmental

on our key personnel, ability to protect our intellectual property and the
impact of future government regulation on our business. You should also consider
carefully the risks described in this Report or detailed from time to time in
our filings with the Securities and Exchange Commission (the "SEC").

                                     PART I

ITEM 1. BUSINESS

Overview

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

                                        2
<PAGE>

         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.

         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 Reticulose 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 Reticulose on virus related
diseases will not be accepted in support of the safety of Reticulose unless we
could establish that the proposed formulation of Reticulose is the same as the
formulation of Reticulose 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

                                        3
<PAGE>

conducted on humans. The FDA also required that the information assure the
proper identification, quality, purity and strength of Reticulose and a
description of the physical, chemical and microbiological characteristics of
Reticulose. 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 to ADVR 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.

         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

                                        4
<PAGE>

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 December 31,
1999 we expended approximately $5.3 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

               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

                                        5

<PAGE>

                  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, ADVR has 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. 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 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.

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
report, 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

                                        7
<PAGE>

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., ADVR's
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 behalf of ADVR with Product R which have since been
concluded. In February 2000, DCT received approval from the ANMAT to proceed
further with Phase I clinical trials in Argentina for Product R. ADVR is
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 Reticulose 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, ADVR intends to manufacture
Product R in Argentina, where it is seeking regulatory approval and therefore
does not need a free sale certificate for Argentina.

         ADVR is currently in the planning stages for the reconfiguration of our
New York research facilities to enable ADVR 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:

         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

                                        9
<PAGE>

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.

         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 25 full-time employees, consisting of our four executive
officers, 18 employees involved in research, and three 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."

ITEM 2.  DESCRIPTION OF PROPERTY

         ADVR leases 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 ADVR's annual rental
obligation under the Yonkers Lease is approximately $260,000.

         ADVR currently maintains 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

                                       10
<PAGE>

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.

ITEM 3.  LEGAL PROCEEDINGS

         ADVR is not currently a party to any material litigation, nor, to the
knowledge of management, is any such litigation currently threatened.

         During 1989, the Commission conducted an informal inquiry into certain
of ADVR's prior disclosure documents, including its original prospectus, press
releases and annual reports. On December 14, 1989, the Commission, as plaintiff,
filed a civil complaint-for permanent injunction and other equitable relief (the
"Complaint") in the United States District Court, Southern District of Florida,
Miami Division, against ADVR, its then President, Bernard Friedland, and its
then Secretary-Treasurer, William Bregman. The Complaint, a copy of which is
filed as an exhibit to ADVR's current report on Form 8-K dated December 14, 1989
which was filed with the Commission (the "December 1989 Form 8-K"), alleged
violations of Sections 5(b)(2) and 17(a) of the Securities Act of 1933, as
amended (the "Securities Act"), Sections l0(b) and 15(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act") and Rules l0b-5, 12b-20,
15d-1 and 15d-13 promulgated thereunder.

         ADVR, Bernard Friedland and William Bregman each, without admitting or
denying the allegations of the Complaint, consented to the entry of an
injunction. Copies of the consents of ADVR, Bernard Friedland and William
Bregman are filed as exhibits to the December 1989 Form 8-K. A permanent
injunction was entered in form and also attached as an exhibit to the December
1989 Form 8-K.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         During the fourth quarter of the fiscal year ended December 31, 1999,
no matters were submitted to a vote of security holders of ADVR.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

         The following discussion of the results of operations and the financial
condition of ADVR should be read in conjunction with ADVR's Consolidated
Financial Statements and Notes thereto included elsewhere in this Report.

Overview

         Since our inception in July 1985, ADVR has been engaged primarily in
research and development activities. We have not yet generated significant
operating revenues, and as of December 31, 1999 we had incurred a cumulative net
loss of $19,725,238. Our ability to generate substantial operating revenue
depends upon our success in gaining FDA approval for the commercial use and
distribution of Product R. 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 IND with the FDA. Filings with foreign
regulatory agencies are required to continue or begin new clinical trials
outside the United States. We have recently 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 ADVR 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 ADVR's 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;

                                       16
<PAGE>


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

               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.

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:

               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.

                                       17

         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

                                       18
<PAGE>

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 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 provided that, if the
registration statement was 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 agrement, 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 are required
to use our best effort to file a registration statement to register the
securities issued or issueble in connection with the agreement by May 31, 2000.

         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
AND DEBT FINANCING 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.

of our common stock on March 27, 2000.

         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,

                                       20
<PAGE>

$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 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
report, 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 to ADVR,
$1,222,500 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

                                       21
<PAGE>

$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
report, 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-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 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 $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 $0.204 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 report, warrants to
purchase 245,098 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-Sholes 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.

                                       22
<PAGE>

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 report, 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-Sholes 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, 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 to ADVR, $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-Sholes 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.

         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

                                       23
<PAGE>

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 report, 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 report, 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-Sholes Pricing Model with the following assumptions:
expected volatility of 20%, and a risk free interest rate of 6% through the June
30, 2004 expiration date. This amount is being 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 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.

         On January 27, February 22, 23, 24, and 29, 2000 pursuant to notice by
Endeavour Capital Fund to ADVR, $150,000, $135,000, $715,000, $785,000 and
$200,000 principal amount of the Endeavour debentures was converted into
1,105,435, 988,913, 5,149,035, 5,562,696 and 1,036,674 shares of common stock,
respectively. As of March 27, 2000, $15,000 of the principal amount of the
debenture remained unconverted.

         In February 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 ADVR. Each warrant contains
anti-dilution provisions which provide for the adjustment of warrant price and
warrant shares. As of the date of this report, none of these warrants had been
exercised.

         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

                                       24
<PAGE>

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 report, none of these warrants
had been exercised.

Projected Expenses

         During the next 12 months, we expect to spend approximately $9,000,000,
approximately $4,000,000 of which was raised during the first quarter of fiscal
2000, on research and development related activities, including approximately:

                  (1)      $4,000,000 for operating expenses;

                  (2)      $2,250,000 for the submission of the IND for Product
                           R to the FDA in connection with GloboMax's project
                           management services to ADVR 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, and toxicology studies of
                           Product R;

                  (3)      $1,500,000 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

                  (4)      $1,250,000 for additional personnel.

         We anticipate that we can continue operations through September 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 $10.6 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
50% 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

                                       25
<PAGE>

financing, licensing agreements, joint ventures and other sources of financing,
but the likelihood of obtaining such financing on favorable terms, if at all, is
small. 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 or comparable approval is obtained from another developed or developing
country. 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.

Year 2000 Compliance

         Many older computer software programs refer to years in terms of their
final two digits only. Such programs may interpret the year 2000 to mean the
year 1900 instead. If not corrected, those programs could cause date-related
transaction failures.

         We developed a compliance assurance process to address this concern. A
project team performed a detailed assessment of all internal computer systems
and developed and implemented plans to correct any problems.

         Year 2000 problems could affect our research and development,
financial, administrative and communication operations. Systems critical to our
business which were identified as non- Year 2000 compliant were either replaced
or corrected through programming modifications. In addition, the project team
looked at Year 2000 readiness from other aspects of our business. We remediated
and replaced systems as needed and have been successfully testing and verifying
our modifications. In addition to our in-house efforts, we have asked vendors,
major customers, service suppliers, communications providers and banks whose
systems failures potentially could have a significant impact on our operations
to verify their Year 2000 readiness. To date, we have not encountered any
significant effects related to the Year 2000 and we do not anticipate that any
unforeseen Year 2000 problems will have a material effect on our results of
operations or financial condition.

         External and internal costs specifically associated with modifying
internal use software for Year 2000 compliance were expensed as incurred and
will not have a material impact on our consolidated financial position, results
of operations or cash flows.

         The above expectations are subject to uncertainties. For example, if we
were unsuccessful in identifying or fixing all Year 2000 problems in our
critical operations, or if we are affected by the inability of certain vendors
or suppliers to continue operations due to such a problem, our results of
operations or financial condition could be materially impacted.

(1)  Dr. Hirschman's salary increased for the year 2000 to $361,000. Mr.
     Gallantar was hired in October 1999 and therefore his salary reflects only
     three months of his $175,000 annual salary.
(2)  Other Annual Compensation for Dr. Hirschman includes medical insurance
     premiums paid by ADVR on his behalf, and aggregate incremental cost to ADVR
     of Dr. Hirschman's automobile lease, gas, oil, repairs and maintenance.
     Other Annual Compensation for Mr. Gallantar includes an automobile
     allowance of $500 per month.
(3)  Includes all options granted during fiscal years shown. No stock
     appreciation rights were granted with any options.
(4)  The dollar value of insurance premiums paid by, or on behalf of, us with
     respect to term life insurance for the benefit of Dr. Hirschman.

         In February 1998, we granted Dr. Hirschman options to acquire
23,000,000 shares of common stock, the exerciseability of which is subject to
conditions precedent. In October 1999, we granted Mr. Gallantar options to
acquire 4,547,880 shares of common stock, exercisable in one third increments on
October 1, 2000, 2001, and 2002, until October 1, 2009. No other stock options
were granted to the named executive officers during 1999. Other than Dr.
Hirschman's and Mr. Gallantar's stock options, we currently have outstanding:

         o        Warrants to purchase 14,247,896 shares of common stock at
                  exercise prices ranging from $0.199 to $0.864 per warrant
                  share;

         o        options to acquire 7,618,234 shares of the common stock at
                  exercise prices ranging from $0.14 to $0.36 per option share,
                  none of which are beneficially owned by directors, officers or
                  employees of ADVR; and

         o        options to acquire 430,000 shares of the common stock at
                  exercise prices of $0.21 per option share, all of which are
                  beneficially owned by employees of ADVR.

         Pursuant to an Amended and Restated Employment Agreement dated as of

Officer and Chairman of our Scientific Advisory Board, with duties including
supervising our day-to-day operations, including management of scientific,
medical, financial, regulatory and corporate matters, establishing appropriate

extension shall be vitiated. If the agreement is terminated by us for cause, we
may cancel all unvested stock options, benefits under stock bonus plans and
stock appreciation rights ("SARs") granted to Dr. Hirschman. If the agreement is
terminated by Dr. Hirschman for cause, we are required to pay to Dr. Hirschman
his annual salary and employee benefits through the remainder of the then
current term.

         Pursuant to the agreement, Dr. Hirschman receives an annual salary of
$325,000, payable in equal biweekly installments. The agreement also entitles
Dr. Hirschman to a major medical insurance policy, disability policy and dental
policy insurance to Dr. Hirschman and his dependents that is reasonably
acceptable to the parties, and a term life insurance policy at least in the
amount of $1,000,000, with a beneficiary to be designated by Dr. Hirschman. The
agreement further provides that we shall:

               o    take such action as may be necessary to permit Dr. Hirschman
                    to be entitled to participate in stock option, stock bonus
                    or similar plans (including plans for SARs) as are
                    established by us;

               o    lease or purchase for Dr. Hirschman, at his discretion, an
                    automobile selected and to be used by him, having a list
                    price not in excess of $40,000, and pay for all gas, oil,
                    repairs and maintenance, as well as the lease or purchase
                    payments, as applicable, in connection with the automobile;

               o    reimburse Dr. Hirschman for all of his proven expenses
                    incurred in and about the course of his employment that are
                    deductible under the current tax law, including, among other
                    expenses, his license fees, membership dues in professional
                    organizations, subscriptions to professional journals,
                    necessary travel, hotel and entertainment expenses incurred
                    in connection with overnight, out-of-town trips that
                    contribute to the benefit of us in the reasonable
                    determination of Dr. Hirschman, and all other expenses that
                    may be pre-approved by our board of directors; and

               o    provide not less than four weeks paid vacation annually and
                    such paid sick or other leave as we provide to all of our
                    employees.

         The agreement also provides for the payment of $100,000 to Dr.
Hirschman on the date we obtain an IND number from the FDA so that Product R may
be tested on humans, so long as such IND number is obtained while Dr. Hirschman
is employed by us.

         The agreement further provides that Dr. Hirschman is not authorized,
without the express written consent of the board of directors and other than in
the ordinary course of business, to pledge the credit of ADVR or any of our
other employees, to bind us, to release or discharge any debt due us unless we
have received payment in full, or to dispose (as collateral or otherwise) of all
or substantially all of our assets.

         Dr. Hirschman has agreed that he will assign to us all patents he
develops which result from his knowledge acquired while performing his duties
under the agreement, and that, if his employment under the agreement is
terminated by us "for cause" or by Dr. Hirschman otherwise than "for cause," as
specified in that agreement, he will not, directly or indirectly, compete with
us for three years after termination or solicit our employees to leave our
employ for one year after termination.

         Pursuant to the execution of the agreement, we ratified a $100,000
bonus payment made to Dr. Hirschman in February 1998 and the February 1998 grant
to Dr. Hirschman of options to acquire 23,000,000 shares of common stock
exercisable at any time and from time to time through February 2008 at $0.27 per

                    FDA so that human research may be conducted using Product R;

               o    the occurrence of a change in control; or

               o    the execution of an agreement relating to co-marketing
                    pursuant to which one or more third parties commit to make
                    payments to us of at least $15 million.

         Gallantar Employment Agreement

         ADVR entered into an Employment Agreement dated as of October 1, 1999
with Alan V. Gallantar, pursuant to which Mr. Gallantar is employed as our Chief
Financial Officer on a full business time basis. Under the agreement, the term
of Mr. Gallantar's employment continues until October 1, 2002. If the agreement
is terminated by us for cause, Mr. Gallantar will have no accrued right to
receive any bonus for the year in which his employment is terminated, all
unvested stock options will be cancelled, and any vested stock options will
terminate 90 days after the effective date of termination. If the agreement is
terminated by ADVR not for cause, we are required to pay to Mr. Gallantar all
accrued and unpaid compensation, and all stock options granted as of the date of
the agreement shall become 100% vested. Upon such termination not for cause, all
options which became vested as a result of this provision may be exercised by
Mr. Gallantar until 90 days after the effective date of termination. If Mr.
Gallantar elects to terminate this agreement as a result of a change in control,
he will be paid his base salary for the remaining term of the agreement, and all
stock options granted on the date of the agreement will become 100% vested and
exercisable until 90 days after the effective date of termination. If Mr.
Gallantar elects to terminate this agreement for any other reason, he will be
paid all unaccrued and unpaid base salary, and he will have the right to
exercise any vested stock until 90 days after the effective date of termination.
All payments made to Mr. Gallantar in connection with the termination of the
agreement are subject to reduction to the extent they exceed 2.99 times the
"base amount" as determined under Section 280G of the Internal Revenue Code of
1986.

         Pursuant to the agreement, Mr. Gallantar will receive an annual salary
of $175,000 for the first year of the agreement; $200,000 for the second year of
the agreement; and $225,000 for the third year of the agreement. For each year
of the agreement, Mr. Gallantar is entitled to a cash bonus of between 10% and
50% of his base salary, based on certain targets and the discretion of the board
of directors. As of the date of the agreement, Mr. Gallantar received options to
purchase an aggregate of 4,547,880 shares of our common stock. The options
expire on October 1, 2009, and are exercisable in three increments of 1,515,960
on the October 1, 2000, 2001 and 2002, respectively. The agreement further
provides that:

               o    Mr. Gallantar and his family are entitled to receive the
                    same benefits generally given to other senior executives of
                    ADVR.

                                       32

               o    Mr. Gallantar is entitled to 15 working days of vacation
                    during the first year and 20 days of vacation during each
                    year thereafter, subject to certain exceptions.

               o    Mr. Gallantar will receive a non-accountable automobile
                    allowance of $500 per month, provided however, that he is be
                    responsible for all costs of acquiring and maintaining the
                    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
                    second anniversary of the agreement, we will pay reasonable
                    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
the express written consent of the board of directors and other than in the
ordinary course of business, to pledge the credit of ADVR, to bind us under any
note, mortgage or other monetary obligation, to release or discharge any debt
due us unless we have received payment in full, or to dispose (as collateral or
otherwise) of a substantial amount of our assets. Furthermore, Mr. Gallantar
agreed that he will assign to us all intellectual property rights developed by
him which result from the knowledge he acquired while performing his duties
under the agreement. Finally, he has agreed that he will not, directly or
indirectly, compete with us for five years after termination of his employment
or solicit our employees to leave our employ for one year after termination.

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

             and denominator of the diluted earnings per share computation.

             Net loss per common share (basic and diluted) is based on the net

             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,
             the FASB issued SFAS No. 137, Accounting for Derivative Instruments
             and Hedging Activities - Deferral of the Effective Date of FASB
             Statement No. 133. SFAS No. 133 as amended by SFAS No. 137 is
             effective for all fiscal quarters of fiscal years beginning after
             June 15, 2000.

             Historically, the Company has not entered into derivatives
             contracts to hedge existing risks or for speculative purposes.
             Accordingly, the Company does not expect adoption of the new
             standard on January 1, 2000 to affect its financial statements.

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.

         The Company maintains certain property and equipment in Freeport,
         Bahamas. This property and equipment amounted to $385,087 as of
         December 31, 1999 and $370,028 as of December 31, 1998 including
         $17,623 expended in 1987 to purchase a land lease expiring in 2068.

         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
             Investors LLC ("Focus"). Accrued interest under

         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-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 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-Sholes 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

             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

             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 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.

         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-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. 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.

             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 were (exercisable
             until March 23, 2001) 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

             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

             is entitled to receive an annual base salary of $325,000 (increased
             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

             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

             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
             shares of common stock of the Company at an exercise price of $.09

             estimated to be $59,030 ($.0347 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. 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-Sholes 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-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.

         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,

         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-Sholes 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

         DISTRIBUTION AGREEMENTS

         The Company currently is a party to separate agreements with five

         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.

         As of December 31, 1999, sufficient uncertainty exists regarding the
         realizability of these operating loss carryforwards and, accordingly, a
         valuation allowance of $4,850,000 has been established.

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.

EXHIBIT 4.24

THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON THE EXERCISE OF THIS
WARRANT (COLLECTIVELY, THE "SECURITIES") HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND MAY NOT BE
OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT, OR
PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS UNDER THE
SECURITIES ACT.

                               WARRANT TO PURCHASE

                    COMMON STOCK, PAR VALUE $.00001 PER SHARE

                                       OF

                          ADVANCED VIRAL RESEARCH CORP.

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

                  This certifies that, for value received, Harbor View Group,
Inc., or registered assigns ("Warrantholder"), is entitled to purchase from
ADVANCED VIRAL RESEARCH CORP. (the "Company"), subject to the provisions of this
Warrant, at any time and from time to time until 5:00 p.m. Eastern Standard Time
on February 28, 2005, 1,750,000 shares of the Company's Common Stock, par value
$.00001 per share ("Warrant Shares"). The purchase price payable upon the
exercise of this Warrant shall be $.21 per Warrant Share. The Warrant Price and
the number of Warrant Shares which the Warrantholder is entitled to purchase is
subject to adjustment upon the occurrence of the contingencies set forth in
Section 3 of this Warrant, and as adjusted from time to time, such purchase
price is hereinafter referred to as the "Warrant Price."

                  This Warrant is subject to the following terms and conditions:

1.       Exercise of Warrant.
         -------------------

         (a)   This Warrant may be exercised in whole or in part but not for a
               fractional share. Upon delivery of this Warrant at the offices of
               the Company or at such other address as the Company may designate
               by notice in writing to the registered holder hereof with the
               Subscription Form annexed hereto duly executed, accompanied by
               payment of the Warrant Price for the number of Warrant Shares
               purchased (in cash, by certified, cashier's or other check
               acceptable to the Company), the registered holder

<PAGE>

               of this Warrant shall be entitled to receive a certificate or
               certificates for the Warrant Shares so purchased. Such
               certificate or certificates shall be promptly delivered to the
               Warrantholder. Upon any partial exercise of this Warrant, the
               Company shall execute and deliver a new Warrant of like tenor for
               the balance of the Warrant Shares purchasable hereunder.

          (b)  The Warrant Shares deliverable hereunder shall, upon issuance, be
               fully paid and non_assessable and the Company agrees that at all
               times during the term of this Warrant it shall cause to be
               reserved for issuance such number of shares of its Common Stock
               as shall be required for issuance and delivery upon exercise of
               this Warrant.

2.       Transfer or Assignment of Warrant.
         ---------------------------------

         (a)   Any assignment or transfer of this Warrant shall be made by
               surrender of this Warrant at the offices of the Company or at
               such other address as the Company may designate in writing to the
               registered holder hereof with the Assignment Form annexed hereto
               duly executed and accompanied by payment of any requisite
               transfer taxes, and the Company shall, without charge, execute
               and deliver a new Warrant of like tenor in the name of the
               assignee for the portion so assigned in case of only a partial
               assignment, with a new Warrant of like tenor to the assignor for
               the balance of the Warrant Shares purchasable.

         (b)   Prior to any assignment or transfer of this Warrant, the holder
               thereof shall deliver an opinion of counsel to the Company to the
               effect that the proposed transfer may be effected without
               registration under the Act.

3.       Adjustment of Warrant Price and Warrant Shares -- Anti_Dilution
         ---------------------------------------------------------------
         Provisions.
         -----------

                  A. (1) Except as hereinafter provided, in case the Company
                  shall at any time after the date hereof issue any shares of
                  Common Stock (including shares held in the Company's treasury)
                  without consideration, then, and thereafter successively upon
                  each issuance, the Warrant Price in effect immediately prior
                  to each such issuance shall forthwith be reduced to a price
                  determined by multiplying the Warrant Price in effect
                  immediately prior to such issuance by a fraction:

                  (a)      the numerator of which shall be the total number of
                           shares of Common Stock outstanding immediately prior
                           to such issuance, and

                  (b)      the denominator of which shall be the total number of
                           shares of Common Stock outstanding immediately after
                           such issuance.

         For the purposes of any computation to be made in accordance with the
provisions of this clause(1), the following provisions shall be made.


<PAGE>


                  (i)      Shares of Common Stock issuable by way of dividend or
                           other distribution on any stock of the Company shall
                           be deemed to have been issued and to be outstanding
                           at the close of business on the record date fixed for
                           the determination of stockholders entitled to receive
                           such dividend or other distribution and shall be
                           deemed to have been issued without consideration.
                           Shares of Common Stock issued otherwise than as a
                           dividend, shall be deemed to have been issued and to
                           be outstanding at the close of business on the date
                           of issue.

                  (ii)     The number of shares of Common Stock at any time
                           outstanding shall not include any shares then owned
                           or held by or for the account of the Company.

                  (2) In case the Company shall at any time subdivide or combine
the outstanding shares of Common Stock, the Warrant Price shall forthwith be
proportionately decreased in the case of the subdivision or proportionately
increased in the case of combination to the nearest one cent. Any such
adjustment shall become effective at the close of business on the date that such
subdivision or combination shall become effective.

         B. In the event that the number of outstanding shares of Common Stock
is increased by a stock dividend payable in shares of Common Stock or by a
subdivision of the outstanding shares of Common Stock, which may include a stock
split, then from and after the time at which the adjusted Warrant Price becomes
effective pursuant to the foregoing Subsection A of this Section by reason of
such dividend or subdivision, the number of shares issuable upon the exercise of
this Warrant shall be increased in proportion to such increase in outstanding
shares. In the event that the number of outstanding shares of Common Stock is
decreased by a combination of the outstanding shares of Common Stock, then, from
and after the time at which the adjusted Warrant Price becomes effective
pursuant to such Subsection A of this Section by reason of such combination, the
number of shares issuable upon the exercise of this Warrant shall be decreased
in proportion to such decrease in outstanding shares.

         C. In the event of an adjustment of the Warrant Price, the number of
shares of Common Stock (or reclassified stock) issuable upon exercise of this
Warrant after such adjustment shall be equal to the number determined by
dividing:

                  (1)      an amount equal to the product of (i) the number of
                           shares of Common Stock issuable upon exercise of this
                           Warrant immediately prior to such adjustment, and
                           (ii) the Warrant Price immediately prior to such
                           adjustment, by

                  (2)      the Warrant Price immediately after such adjustment.

         D. In the case of any reorganization or reclassification of the
outstanding shares of Common Stock (other than a change in par value, or from
par value to no par value, or from no par value to par value, or as a result of
a subdivision or combination) or in the case of any consolidation of the Company
with, or merger of the Company with, another corporation, or in the case of any


<PAGE>

sale, lease or conveyance of all, or substantially all, of the property, assets,
business and goodwill of the Company as an entity, the holder of this Warrant
shall thereafter have the right upon exercise to purchase the kind and amount of
shares of stock and other securities and property receivable upon such
reorganization, reclassification, consolidation, merger or sale by a holder of
the number of shares of Common Stock which the holder of this Warrant would have
received had all Warrant Shares issuable upon exercise of this Warrant been
issued immediately prior to such reorganization, reclassification,
consolidation, merger or sale, at a price equal to the Warrant Price then in
effect pertaining to this Warrant (the kind, amount and price of such stock and
other securities to be subject to adjustment as herein provided).

         E. In case the Company shall, at any time prior to the expiration of
this Warrant and prior to the exercise thereof, dissolve, liquidate or wind up
its affairs, the Warrantholder shall be entitled, upon the exercise thereof, to
receive, in lieu of the Warrant Shares of the Company which it would have been
entitled to receive, the same kind and amount of assets as would have been
issued, distributed or paid to it upon such Warrant Shares of the Company, had
it been the holder of record of shares of Common Stock receivable upon the
exercise of this Warrant on the record date for the determination of those
entitled to receive any such liquidating distribution. After any such
dissolution, liquidation or winding up which shall result in any distribution in
excess of the Warrant Price provided for by this Warrant, the Warrantholder may
at its option exercise the same without making payment of the aggregate Warrant
Price and in such case the Company shall upon the distribution to said
Warrantholder consider that the aggregate Warrant Price has been paid in full to
it and in making settlement to said Warrantholder, shall deduct from the amount
payable to such Warrantholder an amount equal to the aggregate Warrant Price.

         F. In case the Company shall, at any time prior to the expiration of
this Warrant and prior to the exercise thereof make a distribution of assets
(other than cash) or securities of the Company to its stockholders (the
"Distribution") the Warrantholder shall be entitled, upon the exercise thereof,
to receive, in addition to the Warrant Shares it is entitled to receive, the
same kind and amount of assets or securities as would have been distributed to
it in the Distribution had it been the holder of record of shares of Common
Stock receivable upon exercise of this Warrant on the record date for
determination of those entitled to receive the Distribution.

         G. Irrespective of any adjustments in the number of Warrant Shares and
the Warrant Price or the number or kind of shares purchasable upon exercise of
this Warrant, this Warrant may continue to express the same price and number and
kind of shares as originally issued.

4.       Officer's Certificate.
         ---------------------

         Whenever the number of Warrant Shares and the Warrant Price shall be
adjusted pursuant to the provisions hereof, the Company shall forthwith file, at
its principal executive office a statement, signed by the Chairman of the Board,
President, or one of the Vice Presidents of the Company and by its Chief
Financial Officer or one of its Treasurers or Assistant Treasurers, stating the
adjusted number of Warrant Shares and the new Warrant Price calculated to the
nearest one hundredth and setting forth in reasonable detail the method of
calculation and the facts requiring such adjustment and upon which such
calculation is based. Each adjustment shall remain in effect until a subsequent
adjustment hereunder is required. A copy of such statement shall be mailed to
the Warrantholder.


<PAGE>

5.       Charges, Taxes and Expenses.
         ---------------------------

         The issuance of certificates for Warrant Shares upon any exercise of
this Warrant shall be made without charge to the Warrantholder for any tax or
other expense in respect to the issuance of such certificates, all of which
taxes and expenses shall be paid by the Company, and such certificates shall be
issued only in the name of the Warrantholder.

6.       Miscellaneous.
         --------------

         (a)      The terms of this Warrant shall be binding upon and shall
                  inure to the benefit of any successors or assigns of the
                  Company and of the holder or holders hereof and of the shares
                  of Common Stock issued or issuable upon the exercise hereof.

         (b)      No holder of this Warrant, as such, shall be entitled to vote
                  or receive dividends or be deemed to be a stockholder of the
                  Company for any purpose, nor shall anything contained in this
                  Warrant be construed to confer upon the holder of this
                  Warrant, as such, any rights of a stockholder of the Company
                  or any right to vote, give or withhold consent to any
                  corporate action, receive notice of meetings, receive
                  dividends or subscription rights, or otherwise.

         (c)      Receipt of this Warrant by the holder hereof shall constitute
                  acceptance of an agreement to the foregoing terms and
                  conditions.

         (d)      The Warrant and the performance of the parties hereunder shall
                  be construed and interpreted in accordance with the laws of
                  the State of New York and the parties hereunder consent and
                  agree that the State and Federal Courts which sit in the State
                  of New York and the County of New York shall have exclusive
                  jurisdiction with respect to all controversies and disputes
                  arising hereunder.

                  IN WITNESS WHEREOF, the Company has caused this Warrant to be
signed by its duly authorized officer and its corporate seal to be affixed
hereto.

Dated: February 7, 2000

         (b)      The Warrant Shares deliverable hereunder shall, upon issuance,
                  be fully paid and non_assessable and the Company agrees that

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

2.       Transfer or Assignment of Warrant.
         ---------------------------------

         (a)      Any assignment or transfer of this Warrant shall be made by
                  surrender of this Warrant at the offices of the Company or at
                  such other address as the Company may designate in writing to
                  the registered holder hereof with the Assignment Form annexed
                  hereto duly executed and accompanied by payment of any

                  charge, execute and deliver a new Warrant of like tenor in the
                  name of the assignee for the portion so assigned in case of

                  effected without registration under the Act.


3.       Adjustment of Warrant Price and Warrant Shares -- Anti-Dilution
         ---------------------------------------------------------------
         Provisions.

                  A. (1) Except as hereinafter provided, in case the Company
                  shall at any time after the date hereof issue any shares of
                  Common Stock (including shares held in the Company's treasury)
                  without consideration, then, and thereafter successively upon
                  each issuance, the Warrant Price in effect immediately prior
                  to each such issuance shall forthwith be reduced to a price
                  determined by multiplying the Warrant Price in effect
                  immediately prior to such issuance by a fraction:

                                    (a)      the numerator of which shall be the
                                             total number of shares of Common
                                             Stock outstanding immediately prior
                                             to such issuance, and
                                    (b)      the denominator of which shall be
                                             the total number of shares of
                                             Common Stock outstanding
                                             immediately after such issuance.

                  For the purposes of any computation to be made in accordance
with the provisions of this clause (1), the following provisions shall be
applicable:

                           (i)      Shares of Common Stock issuable by way of
                                    dividend or other distribution on any stock
                                    of the Company shall be deemed to have been
                                    issued and to be outstanding at the close


<PAGE>

                                    of business on the record date fixed for the
                                    determination of stockholders entitled to
                                    receive such dividend or other distribution
                                    and shall be deemed to have been issued
                                    without consideration. Shares of Common
                                    Stock issued otherwise than as a dividend,
                                    shall be deemed to have been issued and to
                                    be outstanding at the close of business on
                                    the date of issue.

                           (ii)     The number of shares of Common Stock at any
                                    time outstanding shall not include any
                                    shares then owned or held by or for the
                                    account of the Company.

                           (2) In case the Company shall at any time subdivide
or combine the outstanding shares of Common Stock, the Warrant Price shall
forthwith be proportionately decreased in the case of the subdivision or
proportionately increased in the case of combination to the nearest one cent.
Any such adjustment shall become effective at the close of business on the date
that such subdivision or combination shall become effective.

         B. In the event that the number of outstanding shares of Common Stock
is increased by a stock dividend payable in shares of Common Stock or by a
subdivision of the outstanding shares of Common Stock, which may include a stock
split, then from and after the time at which the adjusted Warrant Price becomes
effective pursuant to the foregoing Subsection A of this Section by reason of
such dividend or subdivision, the number of shares issuable upon the exercise of
this Warrant shall be increased in proportion to such increase in outstanding
shares. In the event that the number of outstanding shares of Common Stock is
decreased by a combination of the outstanding shares of Common Stock, then, from
and after the time at which the adjusted Warrant Price becomes effective
pursuant to such Subsection A of this Section by reason of such combination, the
number of shares issuable upon the exercise of this Warrant shall be decreased
in proportion to such decrease in outstanding shares.

         C. In the event of an adjustment of the Warrant Price, the number of
shares of Common Stock (or reclassified stock) issuable upon exercise of this
Warrant after such adjustment shall be equal to the number determined by
dividing:

                  (1)      an amount equal to the product of (i) the number of
                           shares of Common Stock issuable upon exercise of this
                           Warrant immediately prior to such adjustment, and
                           (ii) the Warrant Price immediately prior to such
                           adjustment, by

                  (2)      the Warrant Price immediately after such adjustment.

         D. In the case of any reorganization or reclassification of the
outstanding shares of Common Stock (other than a change in par value, or from
par value to no par value, or from no par value to par value, or as a result of
a subdivision or combination) or in the case of any consolidation of the Company
with, or merger of the Company with, another corporation, or in the case of any
sale, lease or conveyance of all, or substantially all, of the property, assets,
business and goodwill of the Company as an entity, the holder of this Warrant
shall thereafter have the right upon exercise to purchase the kind and amount of
shares of stock and other securities and property receivable upon


<PAGE>

such reorganization, reclassification, consolidation, merger or sale by a holder
of the number of shares of Common Stock which the holder of this Warrant would
have received had all Warrant Shares issuable upon exercise of this Warrant been
issued immediately prior to such reorganization, reclassification,
consolidation, merger or sale, at a price equal to the Warrant Price then in
effect pertaining to this Warrant (the kind, amount and price of such stock and
other securities to be subject to adjustment as herein provided).

         E. In case the Company shall, at any time prior to the expiration of
this Warrant and prior to the exercise thereof, dissolve, liquidate or wind up
its affairs, the Warrantholder shall be entitled, upon the exercise thereof, to
receive, in lieu of the Warrant Shares of the Company which it would have been
entitled to receive, the same kind and amount of assets as would have been
issued, distributed or paid to it upon such Warrant Shares of the Company, had
it been the holder of record of shares of Common Stock receivable upon the
exercise of this Warrant on the record date for the determination of those
entitled to receive any such liquidating distribution. After any such
dissolution, liquidation or winding up which shall result in any distribution in
excess of the Warrant Price provided for by this Warrant, the Warrantholder may
at its option exercise the same without making payment of the aggregate Warrant
Price and in such case the Company shall upon the distribution to said
Warrantholder consider that the aggregate Warrant Price has been paid in full to
it and in making settlement to said Warrantholder, shall deduct from the amount
payable to such Warrantholder an amount equal to the aggregate Warrant Price.

         F. In case the Company shall, at any time prior to the expiration of
this Warrant and prior to the exercise thereof make a distribution of assets
(other than cash) or securities of the Company to its stockholders (the
"Distribution") the Warrantholder shall be entitled, upon the exercise thereof,
to receive, in addition to the Warrant Shares it is entitled to receive, the
same kind and amount of assets or securities as would have been distributed to
it in the Distribution had it been the holder of record of shares of Common
Stock receivable upon exercise of this Warrant on the record date for
determination of those entitled to receive the Distribution.

         G. Irrespective of any adjustments in the number of Warrant Shares and
the Warrant Price or the number or kind of shares purchasable upon exercise of
this Warrant, this Warrant may continue to express the same price and number and
kind of shares as originally issued.

4.       Officer's Certificate.
         ---------------------

         Whenever the number of Warrant Shares and the Warrant Price shall be
adjusted pursuant to the provisions hereof, the Company shall forthwith file, at
its principal executive office a statement, signed by the Chairman of the Board,
President, or one of the Vice Presidents of the Company and by its Chief
Financial Officer or one of its Treasurers or Assistant Treasurers, stating the
adjusted number of Warrant Shares and the new Warrant Price calculated to the
nearest one hundredth and setting forth in reasonable detail the method of
calculation and the facts requiring such adjustment and upon which such
calculation is based. Each adjustment shall remain in effect until a subsequent
adjustment hereunder is required. A copy of such statement shall be mailed to
the Warrantholder.

5.       Charges, Taxes and Expenses.
         ---------------------------


<PAGE>

         The issuance of certificates for Warrant Shares upon any exercise of
this Warrant shall be made without charge to the Warrantholder for any tax or
other expense in respect to the issuance of such certificates, all of which
taxes and expenses shall be paid by the Company, and such certificates shall be
issued only in the name of the Warrantholder.

6.       Miscellaneous.
         --------------

         (a)      The terms of this Warrant shall be binding upon and shall
                  inure to the benefit of any successors or assigns of the
                  Company and of the holder or holders hereof and of the shares
                  of Common Stock issued or issuable upon the exercise hereof.

         (b)      No holder of this Warrant, as such, shall be entitled to vote
                  or receive dividends or be deemed to be a stockholder of the
                  Company for any purpose, nor shall anything contained in this
                  Warrant be construed to confer upon the holder of this
                  Warrant, as such, any rights of a stockholder of the Company
                  or any right to vote, give or withhold consent to any
                  corporate action, receive notice of meetings, receive
                  dividends or subscription rights, or otherwise.

         (c)      Receipt of this Warrant by the holder hereof shall constitute
                  acceptance of an agreement to the foregoing terms and
                  conditions.

         (d)      The Warrant and the performance of the parties hereunder shall
                  be construed and interpreted in accordance with the laws of
                  the State of New York and the parties hereunder consent and
                  agree that the State and Federal Courts which sit in the State
                  of New York and the County of New York shall have exclusive
                  jurisdiction with respect to all controversies and disputes
                  arising hereunder.

                  IN WITNESS WHEREOF, the Company has caused this Warrant to be
signed by its duly authorized officer and its corporate seal to be affixed
hereto.

THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON THE EXERCISE OF THIS
WARRANT (COLLECTIVELY, THE "SECURITIES") HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND MAY NOT BE
OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT, OR

                               WARRANT TO PURCHASE

                    COMMON STOCK, PAR VALUE $.00001 PER SHARE

                                       OF

                          ADVANCED VIRAL RESEARCH CORP.

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

         This certifies that, for value received, [Name of Purchaser], or
registered assigns ("Warrantholder"), is entitled to purchase from ADVANCED
VIRAL RESEARCH CORP. (the "Company"), subject to the provisions of this Warrant,
at any time and from time to time until 5:00 p.m. Eastern Standard Time on

$.00001 per share ("Warrant Shares"). The purchase price payable upon the
exercise of this Warrant shall be $.275 per Warrant Share. The Warrant Price and
the number of Warrant Shares which the Warrantholder is entitled to purchase is
subject to adjustment upon the occurrence of the contingencies set forth in
Section 3 of this Warrant, and as adjusted from time to time, such purchase
price is hereinafter referred to as the "Warrant Price."

                  This Warrant is subject to the following terms and conditions:

1.       Exercise of Warrant.
         -------------------

         (a)      This Warrant may be exercised in whole or in part but not for
                  a fractional share. Upon delivery of this Warrant at the
                  offices of the Company or at such other address as the Company
                  may designate by notice in writing to the registered holder
                  hereof with the Subscription Form annexed hereto duly
                  executed, accompanied by payment of the Warrant Price for the
                  number of Warrant Shares purchased (in cash, by certified,
                  cashier's or other check acceptable to the Company, by Common
                  Stock of the Company having a Market Value (as hereinafter
                  defined) equal to the aggregate Warrant Price for the Warrant
                  Shares to be purchased, or any combination of the foregoing),
                  the registered holder of this Warrant shall be entitled to
                  receive a certificate or certificates for the Warrant Shares
                  so purchased. Such certificate or


<PAGE>

                  certificates shall be promptly delivered to the Warrantholder.
                  Upon any partial exercise of this Warrant, the Company shall
                  execute and deliver a new Warrant of like tenor for the
                  balance of the Warrant Shares purchasable hereunder.

         (b)      In lieu of exercising this Warrant pursuant to Section 1(a),
                  the holder may elect to receive shares of Common Stock equal
                  to the value of this Warrant determined in the manner
                  described below (or any portion thereof remaining unexercised)
                  upon delivery of this Warrant at the offices of the Company or
                  at such other address as the Company may designate by notice
                  in writing to the registered holder hereof with the Notice of
                  Cashless Exercise Form annexed hereto duly executed. In such
                  event the Company shall issue to the holder a number of shares
                  of the Company's Common Stock computed using the following
                  formula:

                                   X = Y (A-B)
                                       ------
                                        A

Where X = the number of shares of Common Stock to be issued to the holder.
      Y = the number of shares of Common Stock purchasable under this Warrant
          (at the date of such calculation).
      A = the Market Value of the Company's Common Stock on the business day
          immediately preceding the day on which the Notice of Cashless Exercise
          is received by the Company.
      B = Warrant Price (as adjusted to the date of such calculation).

          (c)  The Warrant Shares deliverable hereunder shall, upon issuance, be
               fully paid and non_assessable and the Company agrees that at all
               times during the term of this Warrant it shall cause to be
               reserved for issuance such number of shares of its Common Stock
               as shall be required for issuance and delivery upon exercise of
               this Warrant.

          (d)  For purposes of this Warrant, the Market Value of a share of
               Common Stock on any date shall be equal to (i) the closing bid
               price per share as published by a national securities exchange on
               which shares of Common Stock (or other units of the security) are
               traded (an "Exchange") on such date or, if there is no bid for
               Common Stock on such date, the bid price on such exchange at the
               close of trading on the next earlier date or, (ii) if shares of
               Common Stock are not listed on a national securities exchange on
               such date, the closing bid price per share as published on the
               National Association of Securities Dealers Automatic Quotation
               System ("NASDAQ") National Market System if the shares are quoted
               on such system on such date, or (iii) the closing bid price in

               if the shares are not traded on an exchange or listed on the
               NASDAQ National Market System, or (iv) if the Common Stock is not
               traded on a national securities exchange or in the

               determination of the Market Value of any securities of the
               Company determined by the Board of Directors under Section
               1(d)(iv) the

               Market Value of such securities shall be determined by an
               independent appraiser acceptable to the Company and the holder
               (or, if they cannot agree on such an appraiser, by an independent
               appraiser selected by each of them, and Market Value shall be the
               median of the appraisals made by such appraisers). If there is
               one appraiser, the cost of the appraisal shall be shared equally
               between the Company and the holder. If there are two appraisers,
               each of the Company and the holder shall pay for its own
               appraisal.

2.       Transfer or Assignment of Warrant.
         ---------------------------------

              (a) Any assignment or transfer of this Warrant shall be made by
                  surrender of this Warrant at the offices of the Company or at
                  such other address as the Company may designate in writing to
                  the registered holder hereof with the Assignment Form annexed
                  hereto duly executed and accompanied by payment of any
                  requisite transfer taxes, and the Company shall, without
                  charge, execute and deliver a new Warrant of like tenor in the
                  name of the assignee for the portion so assigned in case of
                  only a partial assignment, with a new Warrant of like tenor to
                  the assignor for the balance of the Warrant Shares
                  purchasable.

              (b) Prior to any assignment or transfer of this Warrant, the
                  holder thereof shall deliver an opinion of counsel to the
                  Company to the effect that the proposed transfer may be
                  effected without registration under the Act.

3.       Adjustment of Warrant Price and Warrant Shares -- Anti-Dilution
         ---------------------------------------------------------------
         Provisions.

         A. (1) Except as hereinafter provided, in case the Company shall at any
time after the date hereof issue any shares of Common Stock (including shares
held in the Company's treasury) without consideration, then, and thereafter
successively upon each issuance, the Warrant Price in effect immediately prior
to each such issuance shall forthwith be reduced to a price determined by
multiplying the Warrant Price in effect immediately prior to such issuance by a
fraction:

                  (a)      the numerator of which shall be the total number of
                           shares of Common Stock outstanding immediately prior
                           to such issuance, and
                  (b)      the denominator of which shall be the total number of
                           shares of Common Stock outstanding immediately after
                           such issuance.

     For the purposes of any computation to be made in accordance with the
provisions of this clause (1), the following provisions shall be applicable:

                  (i)          Shares of Common Stock issuable by way of
                               dividend or other distribution on any stock of
                               the Company shall be deemed to have been issued
                               and to be outstanding at the close of business on
                               the record date fixed for the determination of
                               stockholders entitled to receive such dividend or
                               other distribution and shall be deemed to have
                               been issued without consideration. Shares of
                               Common Stock issued otherwise than as a dividend,
                               shall be deemed to have been issued and to be
                               outstanding at the close of business on the date
                               of issue.

<PAGE>

                  (ii)         The number of shares of Common Stock at any time
                               outstanding shall not include any shares then
                               owned or held by or for the account of the
                               Company.

                      (2) In case the Company shall at any time subdivide or
                  combine the outstanding shares of Common Stock, the Warrant
                  Price shall forthwith be proportionately decreased in the case
                  of the subdivision or proportionately increased in the case of
                  combination to the nearest one cent. Any such adjustment shall
                  become effective at the close of business on the date that
                  such subdivision or combination shall become effective.

         B. In the event that the number of outstanding shares of Common Stock
is increased by a stock dividend payable in shares of Common Stock or by a
subdivision of the outstanding shares of Common Stock, which may include a stock
split, then from and after the time at which the adjusted Warrant Price becomes
effective pursuant to the foregoing Subsection A of this Section by reason of
such dividend or subdivision, the number of shares issuable upon the exercise of
this Warrant shall be increased in proportion to such increase in outstanding
shares. In the event that the number of outstanding shares of Common Stock is
decreased by a combination of the outstanding shares of Common Stock, then, from
and after the time at which the adjusted Warrant Price becomes effective
pursuant to such Subsection A of this Section by reason of such combination, the
number of shares issuable upon the exercise of this Warrant shall be decreased
in proportion to such decrease in outstanding shares.

         C. In the event of an adjustment of the Warrant Price, the number of
shares of Common Stock (or reclassified stock) issuable upon exercise of this
Warrant after such adjustment shall be equal to the number determined by
dividing:

                  (1) an amount equal to the product of (i) the number of shares
                      of Common Stock issuable upon exercise of this Warrant
                      immediately prior to such adjustment, and (ii) the Warrant
                      Price immediately prior to such adjustment, by

                  (2) the Warrant Price immediately after such adjustment.

         D. In the case of any reorganization or reclassification of the
outstanding shares of Common Stock (other than a change in par value, or from
par value to no par value, or from no par value to par value, or as a result of
a subdivision or combination) or in the case of any consolidation of the Company
with, or merger of the Company with, another corporation, or in the case of any
sale, lease or conveyance of all, or substantially all, of the property, assets,
business and goodwill of the Company as an entity, the holder of this Warrant
shall thereafter have the right upon exercise to purchase the kind and amount of
shares of stock and other securities and property receivable upon such
reorganization, reclassification, consolidation, merger or sale by a holder of
the number of shares of Common Stock which the holder of this Warrant would have
received had all Warrant Shares issuable upon exercise of this Warrant been
issued immediately prior to such reorganization, reclassification,
consolidation, merger or sale, at a price equal to the Warrant Price then in
effect

<PAGE>

pertaining to this Warrant (the kind, amount and price of such stock and other
securities to be subject to adjustment as herein provided).

         E. In case the Company shall, at any time prior to the expiration of
this Warrant and prior to the exercise thereof, dissolve, liquidate or wind up
its affairs, the Warrantholder shall be entitled, upon the exercise thereof, to
receive, in lieu of the Warrant Shares of the Company which it would have been
entitled to receive, the same kind and amount of assets as would have been
issued, distributed or paid to it upon such Warrant Shares of the Company, had
it been the holder of record of shares of Common Stock receivable upon the
exercise of this Warrant on the record date for the determination of those
entitled to receive any such liquidating distribution. After any such
dissolution, liquidation or winding up which shall result in any distribution in
excess of the Warrant Price provided for by this Warrant, the Warrantholder may
at its option exercise the same without making payment of the aggregate Warrant
Price and in such case the Company shall upon the distribution to said
Warrantholder consider that the aggregate Warrant Price has been paid in full to
it and in making settlement to said Warrantholder, shall deduct from the amount
payable to such Warrantholder an amount equal to the aggregate Warrant Price.

         F. In case the Company shall, at any time prior to the expiration of
this Warrant and prior to the exercise thereof make a distribution of assets
(other than cash) or securities of the Company to its stockholders (the
"Distribution") the Warrantholder shall be entitled, upon the exercise thereof,
to receive, in addition to the Warrant Shares it is entitled to receive, the
same kind and amount of assets or securities as would have been distributed to
it in the Distribution had it been the holder of record of shares of Common
Stock receivable upon exercise of this Warrant on the record date for
determination of those entitled to receive the Distribution.

         G. Irrespective of any adjustments in the number of Warrant Shares and
the Warrant Price or the number or kind of shares purchasable upon exercise of
this Warrant, this Warrant may continue to express the same price and number and
kind of shares as originally issued.

4.   Officer's Certificate. Whenever the number of Warrant Shares and the
     Warrant Price shall be adjusted pursuant to the provisions hereof, the
     Company shall forthwith file, at its principal executive office a
     statement, signed by the Chairman of the Board, President, or one of the
     Vice Presidents of the Company and by its Chief Financial Officer or one of
     its Treasurers or Assistant Treasurers, stating the adjusted number of
     Warrant Shares and the new Warrant Price calculated to the nearest one
     hundredth and setting forth in reasonable detail the method of calculation
     and the facts requiring such adjustment and upon which such calculation is
     based. Each adjustment shall remain in effect until a subsequent adjustment
     hereunder is required. A copy of such statement shall be mailed to the
     Warrantholder.

5.   Charges, Taxes and Expenses. The issuance of certificates for Warrant
     Shares upon any exercise of this Warrant shall be made without charge to
     the Warrantholder for any tax or other expense in respect to the issuance
     of such certificates, all of which taxes and expenses shall be paid by the
     Company, and such certificates shall be issued only in the name of the
     Warrantholder.

6.   Miscellaneous.

              the benefit of any successors or assigns of the Company and of the
              holder or holders hereof and of the shares of Common Stock issued
              or issuable upon the exercise hereof.

         (b)  No holder of this Warrant, as such, shall be entitled to vote or
              receive dividends or be deemed to be a stockholder of the Company
              for any purpose, nor shall anything contained in this Warrant be
              construed to confer upon the holder of this Warrant, as such, any

              or withhold consent to any corporate action, receive notice of
              meetings, receive dividends or subscription rights, or otherwise.

         (c)  Receipt of this Warrant by the holder hereof shall constitute
              acceptance of an agreement to the foregoing terms and conditions.

         (d)  The Warrant and the performance of the parties hereunder shall be
              construed and interpreted in accordance with the laws of the State
              of New York and the parties hereunder consent and agree that the
              State and Federal Courts which sit in the State of New York and
              the County of New York shall have exclusive jurisdiction with
              respect to all controversies and disputes arising hereunder.

duly authorized officer and its corporate seal to be affixed hereto.

EXHIBIT 4.27

THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON THE EXERCISE OF THIS
WARRANT (COLLECTIVELY, THE "SECURITIES") HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND MAY NOT BE

                               WARRANT TO PURCHASE

                    COMMON STOCK, PAR VALUE $.00001 PER SHARE

                                       OF

                          ADVANCED VIRAL RESEARCH CORP.

     This certifies that, for value received, [Name of Purchaser], or registered
assigns ("Warrantholder"), is entitled to purchase from ADVANCED VIRAL RESEARCH

and as adjusted from time to time, such purchase price is hereinafter referred

         This Warrant is subject to the following terms and conditions:

1.   Exercise of Warrant.
     -------------------

         (a)  This Warrant may be exercised in whole or in part but not for a
              fractional share. Upon delivery of this Warrant at the offices of
              the Company or at such other address as the Company may designate
              by notice in writing to the registered holder hereof with the
              Subscription Form annexed hereto duly executed, accompanied by
              payment of the Warrant Price for the number of Warrant Shares
              purchased (in cash, by certified, cashier's or other check
              acceptable to the Company, by Common Stock of the Company having a
              Market Value (as hereinafter defined) equal to the aggregate
              Warrant Price for the Warrant Shares to be purchased, or any
              combination of the foregoing), the registered holder of this
              Warrant shall be entitled to receive a certificate or certificates
              for the Warrant Shares so purchased. Such certificate or
              certificates shall be promptly delivered


<PAGE>

              to the Warrantholder. Upon any partial exercise of this Warrant,
              the Company shall execute and deliver a new Warrant of like tenor
              for the balance of the Warrant Shares purchasable hereunder.

         (b)  In lieu of exercising this Warrant pursuant to Section 1(a), the
              holder may elect to receive shares of Common Stock equal to the
              value of this Warrant determined in the manner described below (or
              any portion thereof remaining unexercised) upon delivery of this
              Warrant at the offices of the Company or at such other address as
              the Company may designate by notice in writing to the registered
              holder hereof with the Notice of Cashless Exercise Form annexed
              hereto duly executed. In such event the Company shall issue to the
              holder a number of shares of the Company's Common Stock computed
              using the following formula:

                                   X = Y (A-B)
                                       -------
                                        A

Where X = the number of shares of Common Stock to be issued to the holder.

      Y = the number of shares of Common Stock purchasable under this Warrant
          (at the date of such calculation).

      A = the Market Value of the Company's Common Stock on the business day
          immediately preceding the day on which the Notice of Cashless Exercise
          is received by the Company.

      B = Warrant Price (as adjusted to the date of such calculation).

         (c)  The Warrant Shares deliverable hereunder shall, upon issuance, be
              fully paid and non_assessable and the Company agrees that at all
              times during the term of this Warrant it shall cause to be
              reserved for issuance such number of shares of its Common Stock as
              shall be required for issuance and delivery upon exercise of this
              Warrant.

         (d)  For purposes of this Warrant, the Market Value of a share of
              Common Stock on any date shall be equal to (i) the closing bid
              price per share as published by a national securities exchange on
              which shares of Common Stock (or other units of the security) are
              traded (an "Exchange") on such date or, if there is no bid for
              Common Stock on such date, the bid price on such exchange at the
              close of trading on the next earlier date or, (ii) if shares of
              Common Stock are not listed on a national securities exchange on
              such date, the closing bid price per share as published on the
              National Association of Securities Dealers Automatic Quotation
              System ("NASDAQ") National Market System if the shares are quoted
              on such system on such date, or (iii) the closing bid price in the
              over-the-counter market at the close of trading on such date if
              the shares are not traded on an exchange or listed on the NASDAQ
              National Market System, or (iv) if the Common Stock is not traded
              on a national securities exchange or in the over-the-counter
              market, the fair market value of a share of Common Stock on such
              date as determined in good faith by the Board of Directors. If the
              holder disagrees with the determination of the Market Value of any
              securities of the Company determined by the Board of Directors
              under Section 1(d)(iv) the Market Value of such securities shall
              be determined by an independent appraiser acceptable to the
              Company and the holder (or, if they cannot agree on such an
              appraiser,

<PAGE>

              by an independent appraiser selected by each of them, and Market
              Value shall be the median of the appraisals made by such
              appraisers). If there is one appraiser, the cost of the appraisal
              shall be shared equally between the Company and the holder. If
              there are two appraisers, each of the Company and the holder shall
              pay for its own appraisal.

2.       Transfer or Assignment of Warrant.
         ---------------------------------

              (a) Any assignment or transfer of this Warrant shall be made by
                  surrender of this Warrant at the offices of the Company or at
                  such other address as the Company may designate in writing to
                  the registered holder hereof with the Assignment Form annexed
                  hereto duly executed and accompanied by payment of any
                  requisite transfer taxes, and the Company shall, without
                  charge, execute and deliver a new Warrant of like tenor in the
                  name of the assignee for the portion so assigned in case of
                  only a partial assignment, with a new Warrant of like tenor to
                  the assignor for the balance of the Warrant Shares
                  purchasable.

              (b) Prior to any assignment or transfer of this Warrant, the
                  holder thereof shall deliver an opinion of counsel to the
                  Company to the effect that the proposed transfer may be
                  effected without registration under the Act.

3.       Adjustment of Warrant Price and Warrant Shares -- Anti-Dilution
         ---------------------------------------------------------------
         Provisions.
         -----------

         A. (1) Except as hereinafter provided, in case the Company shall at any
time after the date hereof issue any shares of Common Stock (including shares
held in the Company's treasury) without consideration, then, and thereafter
successively upon each issuance, the Warrant Price in effect immediately prior
to each such issuance shall forthwith be reduced to a price determined by
multiplying the Warrant Price in effect immediately prior to such issuance by a
fraction:

                  (a)      the numerator of which shall be the total number of
                           shares of Common Stock outstanding immediately prior
                           to such issuance, and
                  (b)      the denominator of which shall be the total number of
                           shares of Common Stock outstanding immediately after
                           such issuance.

     For the purposes of any computation to be made in accordance with the
provisions of this clause (1), the following provisions shall be applicable:

                  (i)          Shares of Common Stock issuable by way of
                               dividend or other distribution on any stock of
                               the Company shall be deemed to have been issued
                               and to be outstanding at the close of business on
                               the record date fixed for the determination of
                               stockholders entitled to receive such dividend or
                               other distribution and shall be deemed to have
                               been issued without consideration. Shares of
                               Common Stock issued otherwise than as a dividend,
                               shall be deemed to have been issued and to be
                               outstanding at the close of business on the date
                               of issue.

                  (ii)         The number of shares of Common Stock at any time
                               outstanding shall not include any shares then
                               owned or held by or for the account of the
                               Company.


<PAGE>


                      (2) In case the Company shall at any time subdivide or
                  combine the outstanding shares of Common Stock, the Warrant
                  Price shall forthwith be proportionately decreased in the case
                  of the subdivision or proportionately increased in the case of
                  combination to the nearest one cent. Any such adjustment shall
                  become effective at the close of business on the date that
                  such subdivision or combination shall become effective.

         B. In the event that the number of outstanding shares of Common Stock
is increased by a stock dividend payable in shares of Common Stock or by a
subdivision of the outstanding shares of Common Stock, which may include a stock
split, then from and after the time at which the adjusted Warrant Price becomes
effective pursuant to the foregoing Subsection A of this Section by reason of
such dividend or subdivision, the number of shares issuable upon the exercise of
this Warrant shall be increased in proportion to such increase in outstanding
shares. In the event that the number of outstanding shares of Common Stock is
decreased by a combination of the outstanding shares of Common Stock, then, from
and after the time at which the adjusted Warrant Price becomes effective
pursuant to such Subsection A of this Section by reason of such combination, the
number of shares issuable upon the exercise of this Warrant shall be decreased
in proportion to such decrease in outstanding shares.

         C. In the event of an adjustment of the Warrant Price, the number of
shares of Common Stock (or reclassified stock) issuable upon exercise of this
Warrant after such adjustment shall be equal to the number determined by
dividing:

                  (1) an amount equal to the product of (i) the number of shares
                      of Common Stock issuable upon exercise of this Warrant
                      immediately prior to such adjustment, and (ii) the Warrant
                      Price immediately prior to such adjustment, by

                  (2) the Warrant Price immediately after such adjustment.

         D. In the case of any reorganization or reclassification of the
outstanding shares of Common Stock (other than a change in par value, or from
par value to no par value, or from no par value to par value, or as a result of
a subdivision or combination) or in the case of any consolidation of the Company
with, or merger of the Company with, another corporation, or in the case of any
sale, lease or conveyance of all, or substantially all, of the property, assets,
business and goodwill of the Company as an entity, the holder of this Warrant
shall thereafter have the right upon exercise to purchase the kind and amount of
shares of stock and other securities and property receivable upon such
reorganization, reclassification, consolidation, merger or sale by a holder of
the number of shares of Common Stock which the holder of this Warrant would have
received had all Warrant Shares issuable upon exercise of this Warrant been
issued immediately prior to such reorganization, reclassification,
consolidation, merger or sale, at a price equal to the Warrant Price then in
effect pertaining to this Warrant (the kind, amount and price of such stock and
other securities to be subject to adjustment as herein provided).

<PAGE>

         E. In case the Company shall, at any time prior to the expiration of
this Warrant and prior to the exercise thereof, dissolve, liquidate or wind up
its affairs, the Warrantholder shall be entitled, upon the exercise thereof, to
receive, in lieu of the Warrant Shares of the Company which it would have been
entitled to receive, the same kind and amount of assets as would have been
issued, distributed or paid to it upon such Warrant Shares of the Company, had
it been the holder of record of shares of Common Stock receivable upon the
exercise of this Warrant on the record date for the determination of those
entitled to receive any such liquidating distribution. After any such
dissolution, liquidation or winding up which shall result in any distribution in
excess of the Warrant Price provided for by this Warrant, the Warrantholder may
at its option exercise the same without making payment of the aggregate Warrant
Price and in such case the Company shall upon the distribution to said
Warrantholder consider that the aggregate Warrant Price has been paid in full to
it and in making settlement to said Warrantholder, shall deduct from the amount
payable to such Warrantholder an amount equal to the aggregate Warrant Price.

         F. In case the Company shall, at any time prior to the expiration of
this Warrant and prior to the exercise thereof make a distribution of assets
(other than cash) or securities of the Company to its stockholders (the
"Distribution") the Warrantholder shall be entitled, upon the exercise thereof,
to receive, in addition to the Warrant Shares it is entitled to receive, the
same kind and amount of assets or securities as would have been distributed to
it in the Distribution had it been the holder of record of shares of Common
Stock receivable upon exercise of this Warrant on the record date for
determination of those entitled to receive the Distribution.

         G. Irrespective of any adjustments in the number of Warrant Shares and
the Warrant Price or the number or kind of shares purchasable upon exercise of
this Warrant, this Warrant may continue to express the same price and number and
kind of shares as originally issued.

4.   Officer's Certificate. Whenever the number of Warrant Shares and the
     Warrant Price shall be adjusted pursuant to the provisions hereof, the
     Company shall forthwith file, at its principal executive office a
     statement, signed by the Chairman of the Board, President, or one of the
     Vice Presidents of the Company and by its Chief Financial Officer or one of
     its Treasurers or Assistant Treasurers, stating the adjusted number of
     Warrant Shares and the new Warrant Price calculated to the nearest one
     hundredth and setting forth in reasonable detail the method of calculation
     and the facts requiring such adjustment and upon which such calculation is
     based. Each adjustment shall remain in effect until a subsequent adjustment
     hereunder is required. A copy of such statement shall be mailed to the
     Warrantholder.

5.   Charges, Taxes and Expenses. The issuance of certificates for Warrant
     Shares upon any exercise of this Warrant shall be made without charge to
     the Warrantholder for any tax or other expense in respect to the issuance
     of such certificates, all of which taxes and expenses shall be paid by the
     Company, and such certificates shall be issued only in the name of the
     Warrantholder.

6.       Miscellaneous.
         --------------

         (a)  The terms of this Warrant shall be binding upon and shall inure to
              the benefit of any successors or assigns of the Company and of the
              holder or holders hereof and of the shares of Common Stock issued
              or issuable upon the exercise hereof.

         (b)  No holder of this Warrant, as such, shall be entitled to vote or
              receive dividends or be deemed to be a stockholder of the Company
              for any purpose, nor shall anything contained in this Warrant be
              construed to confer upon the holder of this Warrant, as such, any
              rights of a stockholder of the Company or any right to vote, give
              or withhold consent to any corporate action, receive notice of
              meetings, receive dividends or subscription rights, or otherwise.

              (c) Receipt of this Warrant by the holder hereof shall constitute
              acceptance of an agreement to the foregoing terms and conditions.

         (d)  The Warrant and the performance of the parties hereunder shall be
              construed and interpreted in accordance with the laws of the State
              of New York and the parties hereunder consent and agree that the
              State and Federal Courts which sit in the State of New York and
              the County of New York shall have exclusive jurisdiction with

Exhibit C, the Company represents and warrants as follows:

organized and validly existing and in good standing under the laws of its
jurisdiction of incorporation, and has all requisite corporate power and
authority to carry on its business as now conducted and proposed to be
conducted; the Company has all requisite corporate power and authority to enter
into this Agreement, to issue the Securities as contemplated herein and to carry
out and perform its obligations under the terms and conditions of this
Agreement. The Company does not own or lease any property or engage in any
activity in any jurisdiction which might require qualification to do business as
a foreign corporation in such jurisdiction and where the failure to so qualify
would have a material adverse effect on the financial condition of the Company
or subject the Company to a material liability. To the extent the Company has
not qualified to do business in such jurisdictions, it has, as of the date
hereof, prepared the necessary applications or documents to be filed with the
appropriate authorities in such jurisdictions to obtain such qualifications. The
Company has furnished each Purchaser with true, correct and complete copies of
its Certificate of Incorporation, By-laws and all amendments thereto to date.

<PAGE>

         4.2. Authorization. All corporate action on the part of the Company
and the directors and stockholders of the Company necessary for the
authorization, execution, delivery and performance by the Company of this
Agreement and the transactions contemplated herein, and for the authorization,
issuance and delivery of the Securities, has been taken or will have been taken
prior to the Closing.

         4.3. Binding Obligations; No Material Adverse Contracts, etc. This
Agreement is a valid and binding obligation of the Company enforceable in
accordance with its terms. The execution, delivery and performance by the
Company of this Agreement and compliance herewith will not result in any
violation of and will not conflict with, or result in a breach of any of the
terms of, or constitute a default under, any provision of state or Federal law
to which the Company is subject, the Certificate of Incorporation, as amended,

agreement, instrument, judgment, decree, order, rule or regulation or other
restriction to which the Company is a party or by which it is bound, or, result

the issuance of the Securities.

         4.4. Offering. Subject in part to the truth and accuracy of the
representations made by each Purchaser herein and such Purchaser's compliance
with his covenants set forth in this Agreement, the offer, sale and issuance of
the Securities as contemplated by this Agreement are not subject to the
registration requirements of the Securities Act, and the Company, or anyone
acting on its behalf, will not take any action hereafter that would cause such
registration requirements to be applicable.

statement of operations, of stockholders' equity and of cash flows presents
fairly in accordance with GAAP the results of operations, the stockholders'
equity and the cash flows of the Company for the periods then ended.

         (b) No event has occurred since December 31, 1998 requiring the filing
of an SEC Report that has not heretofore been filed.

         (c) The SEC Reports and this Agreement taken together as a whole will
not, as of the Closing Date, contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein, or necessary to
make the statements contained therein, in light of the circumstances under which
they were made, not misleading.

<PAGE>

pursuant to this Agreement, and each of the agreements, documents, certificates
and writings previously delivered to Purchaser or his representatives, do not
and will not contain any untrue statement of material fact and do not and will

adversely affects the business, prospects or condition (financial or otherwise)
of the Company which has not been set forth herein.

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

         The Purchasers and the Company hereby covenant and agree as follows:

         7.1. Further Assurances. From time to time the Company shall execute
and deliver to each Purchaser and each Purchaser shall execute and deliver to

before May 31, 2000, a registration statement (the "Registration Statement")
with the Commission, on such form as the Company deems to be appropriate, to
register the Shares under the Securities Act. The Company shall thereafter use
its best efforts to cause the Registration Statement to be declared effective by
the Commission.

                  (b) Each Purchaser shall furnish to the Company such
information as the Company shall reasonably request in writing and as shall be
required in connection with the registration.

         7.3.    Indemnification.
                 ---------------

                  (a) The Company agrees to indemnify and hold each Purchaser
harmless from and against any losses, claims, damages or liabilities to which
such Purchaser may become subject (under the Securities Act or otherwise)
insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of, or are based upon, any Untrue
Statement (as defined below) on or after the effective date of the Registration
Statement, or arise out of any failure by the Company to fulfill any undertaking
included in the Registration Statement and the Company will

<PAGE>

reimburse such Purchaser any reasonable legal or other expenses reasonably
incurred in investigating, defending or preparing to defend any such action,
proceeding or claim; provided, however, that the Company shall not be liable in
any such case to the extent that such loss, claim, damage or liability arises
out of, or is based upon, an Untrue Statement made in such Registration
Statement in reliance upon and in conformity with written information furnished
to the Company by such Purchaser or on such Purchaser's behalf, specifically for
use in preparation of the Registration Statement, or any statement or omission
in any prospectus that is corrected in any subsequent prospectus that was
delivered prior to the pertinent sale or sales by such Purchaser of his Shares.

                  (b) Each Purchaser agrees to indemnify and hold harmless the
Company and each person, if any, who controls the Company within the meeting of
Section 15 of the Securities Act, each officer of the Company who signs the
Registration Statement and each director of the Company from and against any
losses, claims, damages or liabilities to which the Company or any such officer,
director or controlling person may become subject (under the Securities Act or
otherwise), insofar as such losses, claims, damages or liabilities (or actions
or proceedings in respect thereof) arise out of, or are based upon, any failure
to comply with such Purchaser's representation and warranties hereunder, or any
Untrue Statement contained in the Registration Statement on or after the
effective date thereof if such Untrue Statement was made in reliance upon and in
conformity with written information furnished by such Purchaser or on such
Purchaser's behalf specifically for use in preparation of the Registration
Statement, as the case may be, for any legal or other expenses reasonably
incurred in investigating, defending or preparing to defend any such action,
proceeding or claim; provided, however, that in no event shall such Purchaser's
indemnity exceed the gross proceeds received by Purchaser from the sale of
Shares covered by such Registration Statement.

                  (c) Promptly after receipt by any indemnified person of a
notice of a claim or the beginning of any action in respect of which indemnity
is to be sought against an indemnifying person pursuant to this section, such
indemnified person shall notify the indemnifying person in writing of such claim
or of the commencement of such action, and, subject to the provisions
hereinafter stated, in case any such action shall be brought against an
indemnified person and such indemnifying person shall have been notified
thereof, such indemnifying person shall be entitled to participate therein, and,
to the extent it shall wish, to assume the defense thereof, with counsel
reasonably satisfactory to such indemnified person. After notice from the
indemnifying person to such indemnified person of its election to assume the
defense thereof, such indemnifying person shall not be liable to such
indemnified person for any legal expenses subsequently incurred by such
indemnified person in connection with the defense thereof; provided, however,
that if there exists or shall exist a conflict of interest that would make it
inappropriate, in the opinion of counsel to the indemnified person, for the same
counsel to represent both the indemnified person and such indemnifying person or
any affiliate or associate thereof, the indemnified person shall be entitled to
retain its own counsel at the expense of such indemnifying person; provided
further, however, that no indemnifying person shall be responsible for the fees
and expenses of more than one separate counsel for all indemnified parties.

                  (d) "Untrue Statement" means any untrue statement or alleged
untrue statement, or any omission or alleged omission to state in the
Registration Statement a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.
