                               PROSPECTUS SUMMARY

         The following summary may not contain all the information that is
important to you. You should carefully review the information appearing
elsewhere in this prospectus, in particular the 'Risk Factors' section and the
Consolidated Financial Statements and Notes thereto. Except where noted in the
text, all information in this prospectus assumes (i) the issuance of 9,057,971
shares of AVR common stock upon the full conversion of a convertible debenture
dated as of November 16, 1998 in the aggregate principal amount of $1,500,000
(the "1998 Debenture"); (ii) the issuance of 5,451,922 shares of AVR common
stock upon the full exercise of outstanding warrants (the "Warrants"); and (iii)
the issuance of 27,765,415 shares of AVR common stock upon the full exercise of
outstanding stock options (the "Options").

GENERAL INFORMATION REGARDING AVR

         Advanced Viral Research Corp. ("AVR") was incorporated in Delaware on
July 31, 1985 to engage in the production and marketing, promotion and sale of
the pharmaceutical product Reticulose(Trademark) ("Reticulose"). AVR is in the
developmental stage, and has not yet commenced any commercial operations. AVR's
offices are located at 1250 East Hallandale Beach Boulevard, Suite 501,
Hallandale, Florida 33009 and 200 Corporate Boulevard South, Yonkers, New York
10701. Its telephone number in Hallandale, Florida is (954) 458-7636 and its
telephone number in Yonkers, New York is (914) 376-7383.

         Reticulose has not been registered or approved for commercial
distribution by the Food and Drug Administration of the United States Department
of Health and Human Services ("FDA"), or any other applicable foreign government
body. AVR is dependent on such registration and/or approval of Reticulose in
order to commence commercial operations, and sales of Reticulose will not be
significant unless such approval is granted. FDA approval first requires
clinical testing of Reticulose in human trials, and such clinical testing cannot
be conducted in the United States until AVR satisfies the FDA's requirements in
its Notice of Claimed Investigational Exemption for a New Drug ("IND") for
Reticulose. Although AVR is currently working towards the submission of a new
IND to the FDA, no assurance can be given that the IND will ever be submitted,
or if submitted that the FDA will approve such IND, or if such approval is
granted, that, in the absence of grants or other subsidies, AVR will be able to
fund the first phase of human clinical trials. If AVR needs additional financing
to fund such human clinical trials, there can be no assurance that additional
financing will be available to AVR. No assurance can be given that the results
of such human clinical trials will prove that Reticulose is safe or effective in
the treatment of any diseases. No assurance can be given that the FDA will ever
permit the commercial distribution of Reticulose in the United States.

         AVR's operations over the last five years have been limited principally
to engaging in research, in vitro testing and analysis of Reticulose in the
United States, and engaging others to perform testing and analysis of Reticulose
on human patients outside the United States. In connection with these
engagements, AVR has also granted distribution rights for Reticulose in certain
foreign countries. Shalom Hirschman, M.D., President of AVR, has monitored the
testing of Reticulose and has recently performed certain analyses of Reticulose
with Company 

                                        1

personnel, which analyses AVR believes may be used in connection with the FDA
approval process. In addition, AVR has recently contracted with GloboMax LLC of
Hanover, Maryland to advise AVR in its preparation of an IND to be filed with
the FDA, and to otherwise assist AVR through the FDA process with the objective
of obtaining full approval for Reticulose in the United States. There can be no
assurances as to the costs or the timing of the filing of the new IND or whether
AVR has the resources to complete the FDA approval process.

         AVR's common stock is subject to the Securities Enforcement and Penny
Stock Reform Act of 1990, which requires additional disclosure relating to the
market for penny stocks in connection with trades in any stock defined as a
penny stock. Commission regulations generally define a penny stock to be an
equity security that has a market price of less than $5.00 per share, subject to
certain exceptions. Unless an exception is available, the regulations require
the delivery, prior to any transaction involving a penny stock, of a disclosure
schedule explaining the penny stock market and the risks associated therewith.

         In addition, because AVR's securities do not meet the exceptions to the
penny stock regulations cited above, trading in AVR's securities is covered by
Rule 15g-9 promulgated under the Securities Exchange Act of 1934 for securities
that are not listed on The Nasdaq Stock Market or any national securities
exchange. Under such rule, broker/dealers who recommend such securities to
persons other than established customers and accredited investors must make a
special written suitability determination for the purchaser and receive the
purchaser's written 

                                        3

<PAGE>


agreement to a transaction prior to sale. Securities also are exempt from this
rule if the market price is at least $5.00 per share.

         Because AVR's securities are subject to the regulations applicable to
penny stocks, the market liquidity for AVR's securities may be adversely
affected. The regulations on penny stocks limit the ability of broker/dealers to
sell AVR's securities and thus the ability of purchasers of AVR's securities to
sell their securities in the secondary market. In addition, certain states may
have rules and regulations that impose additional sales practice requirements on
broker-dealers who sell the common stock.

Commercial Viability Dependent on Approval of Reticulose for Sale by the FDA.

         AVR has a very limited operating history, insignificant operating
revenues and must be considered promotional and still in its early developmental
stage. From inception through December 31, 1998, AVR had an accumulated deficit
of $12,978,059. AVR is dependent upon approval of Reticulose for sale before it
can begin any significant commercial operations.

         Management does not anticipate registration or other approval of
Reticulose in an industrialized country in the immediate future. Management of
AVR believes that the United States constitutes one of the major and most
profitable pharmaceutical markets in the world. Since 1962, when Reticulose,
among many other drugs, was reclassified as a "new drug" by the FDA, Reticulose
has not been permitted to be marketed in the United States. This has been the
direct result of AVR's inability to satisfy the regulatory protocols and the
substantial preapproval requirements imposed by the FDA upon the introduction of
any new or unapproved drug product, which include lengthy and detailed
laboratory and clinical testing procedures, sampling activities and other costly
and time consuming procedures. There is no assurance that FDA approval for the
sale of Reticulose in the United States will ever be obtained or that the
results of any clinical studies and tests will be sufficient to lead to FDA
approval of an IND for clinical testing of Reticulose on humans in the United
States. Further, there can be no assurance that Reticulose will ever be approved
for commercial distribution by any country. There is nothing at this time upon
which to base any assumption that AVR will either generate operating revenues or
will ever be able to operate on a profitable basis. If AVR's plans prove to be
unsuccessful, its shareholders and holders of options and warrants may lose all
or a substantial portion of their investment. See "Business -- Competition," 
"-- Testing Agreements," "-- Exclusive Distribution Agreements" and "Government
Regulation; the Investigational New Drug Application Process."

Funds Inadequate for Continued Research, Development and Testing; Uncertainty as
Going Concern

         AVR's cash position, from time to time, has been the result of proceeds
from AVR's sale of securities, to a much lesser extent, fees paid for
distribution rights by AVR's exclusive distributors which fees also included
deposits on purchases of Reticulose by a distributor, and limited sales of
Reticulose for testing purposes. AVR's cash position of approximately $1,750,000
as of December 31, 1998 is largely due to stock options being exercised and the
proceeds of convertible debentures sold in 1997 and 1998. AVR's current cash
position will not 

                                        4

<PAGE>


be adequate to pay all the costs associated with the full range of continued
research and development and testing, as well as the clinical trials that may be
required by the FDA in order to obtain approval for the IND to test Reticulose
in the United States.

         Unless Reticulose is approved for sale in the United States or another
such country or unless Reticulose is approved for sale in one or more of its
distributors' territories with both a material population and healthy profile,
AVR may require additional equity and/or debt financing in the future to meet
the considerable costs of human clinical trials, should the FDA grant permission
for such trials. Such costs have not been ascertained by AVR. AVR may be
dependent upon the continued sale of its securities or the exercise of its
outstanding options or warrants for funds to meet its cash requirements. Any
issuance of a substantial number of additional shares of common stock would
dilute the ownership of present shareholders. If no options or warrants are
exercised, management believes that AVR will be able to continue its business,
which remains in the development stage, at current levels for approximately 12
months. There can be no assurance that the Options or the Warrants will be
exercised in their entirety, if at all. There can be no assurance that any
additional financing will be available or, if available, that it can be obtained
on terms satisfactory to management. If AVR does not obtain material proceeds
from the exercise of the Options or Warrants, AVR could be dependent upon joint
ventures with, or the sale of certain rights regarding Reticulose to, third
parties, the terms of which might not be advantageous to AVR. In addition, AVR
may seek debt financing, but no agreements have been entered into or identified
with regard to any financing. In the event that debt financing is not available,
management anticipates that they will have to defer their salaries in order to
continue operations. No assurances can be given that other debt financing will
be readily obtainable on favorable terms, that AVR will be able to sustain its
operations until approval for sale of Reticulose is granted or that any such
approval will be granted. 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 AVR be
unable to continue in existence. See "Management's Discussion and Analysis and
Results of Operations" and "Notes to Consolidated Financial Statements."

         AVR's independent certified public accountants' report on AVR's
consolidated financial statements for the fiscal year ended December 31, 1998,
includes an explanatory paragraph regarding AVR's ability to continue as a going
concern. Note 2 to the Consolidated Financial Statements stating that AVR's
ability to continue operations is dependent upon its continued sale of its
securities for funds to meet its cash requirements, which factors raise
substantial doubt about AVR's 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. AVR has no immediate plan to issue any
securities, otherwise than upon the possible exercise of the Options, the
Warrants, or the conversion of the 1998 Debenture. AVR has suffered material
losses from operations during its operating history.

Reticulose is AVR's Sole Product; Very Limited Sales for Testing Purposes Only.

         There have been no sales by AVR of Reticulose except for insignificant
revenues related to distribution of the drug for testing purposes. Reticulose is
not currently marketed or approved for sale or use, and there can be no
assurance that it will be approved for sale or use in the future.


                                       5

AVR has currently in effect exclusive distribution agreements with distributors
to market and sell Reticulose, subject to each distributor obtaining regulatory
approval, in the following countries: China, Japan, Hong Kong, Macao, and Taiwan
(AVIX International Pharmaceutical Corp., a New York corporation ("AVIX"));
Mexico (AVIX); Channel Islands, Isle of Man, British West Indies, Jamaica,
Haiti, Bermuda, Belize and Saudi Arabia (Commonwealth Pharmaceuticals, a
corporation organized under the laws of Cayman Islands, British West Indies
("Commonwealth")); and Argentina, Bolivia, Paraguay, Uruguay, Brazil, and Chile
(DCT). AVR is dependent upon obtaining regulatory approval of Reticulose for
sale and use in the United States, in other developed countries, or
alternatively in one or more of its distributors' territories in order to have
the potential for significant distribution and sales of Reticulose. There can be
no assurance that any sales will be generated by AVR's distribution agreements,
and further, there can be no assurance that any such distributors will receive
timely, if ever, necessary approvals to market Reticulose in their territories.
See "Business -- Exclusive Distribution Agreements."

Limited Medical Acceptance and No Assurance of Effectiveness of Reticulose.

         Reticulose is neither widely known nor accepted by the medical
community nor approved for use in the United States for any purpose by the FDA.
Two articles published in 1962 in recognized medical journals have questioned
the anti-viral effect of Reticulose on Mumps, Encephalitis and Herpes Simplex
utilizing tissue culture; on Herpes Simplex in students; and on Lansing Polio
and mouse adapted and egg adapted Influenza: A. C. Kempe, "Failure to
Demonstrate Antiviral Activity of Reticulose," American Journal of Diseases of
Children, Vol. 103, May 1962, and Behbehani, "The Effect of Reticulose on Viral
Infections of Experimental Animals," Southern Medical Journal, Vol. 55, February
1962. The only "double blind" study of Reticulose completed by or for AVR is a
clinical trial involving 43 human patients with the AIDS which took place in
Bridgetown, Barbados.

         Upon AVR's filing of a new IND application with the FDA, it must first
satisfy the FDA that the current formulation of Reticulose is identical to the
formulation reported on in the prior anecdotal history and studies of
Reticulose, of which there can be no assurance. The uncertain amount of time and
costs required for IND approval as a result of the FDA not accepting the prior
history of the drug can be expected to be financially burdensome and have a
material adverse effect on AVR and its likelihood of ever obtaining any
requisite approval in the United States.

         There can be no assurance that the FDA will approve the sale or even
the testing on humans of Reticulose in the United States, or that Reticulose
will be effective in treating viruses of any variety on a wide scale or any
other basis. See "Management's Discussion and Analysis and Results of
Operations," "Business -- The Investigational New Drug Process" and "Testing
Agreements."

Complexity and Expense of Complying with Government Regulations.

         The FDA and comparable regulatory agencies in foreign countries impose
substantial requirements upon the introduction of therapeutic drug products
including lengthy and detailed laboratory and clinical testing procedures,
sampling activities and other costly and time consuming procedures. Registration
or approval of a pharmaceutical product in at least one other country is a
prerequisite to obtaining registration for sale in many Third World countries.
Such governmental regulation decreases the likelihood that FDA approval for the
sale of Reticulose in the United States or elsewhere will ever be obtained or
that AVR will have adequate funds to finance the necessary clinical studies and
related costs. In addition, the effect of the FDA and foreign government
regulation will be to delay marketing of Reticulose for a considerable period of
time, to impose costly procedures upon AVR's activities and to impede and/or
prevent AVR's ability to compete with larger companies in its industry. The
extent of potentially adverse government regulations which might arise from
future legislation or administrative action cannot be predicted.

Intense Competition in Pharmaceutical Industry.

         There are inherent difficulties for any development stage company, such
as AVR, seeking to enter an established field, particularly a field as capital
intensive as the manufacture and sale of pharmaceuticals. AVR can expect to
encounter intense competition from well known pharmaceutical companies and
chemical companies engaged in the development and marketing of therapeutic drug
products. Almost all of such companies are substantially larger, possessing far
greater capital resources, more substantial operating histories and records of
successful operations, greater personnel and other resources, and more extensive
facilities than AVR now has or will have in the foreseeable future. Thus, such
companies are and probably will continue to remain in a far better position to
compete in this industry than AVR. Such companies may succeed in discovering,
developing and marketing products that are either as effective or more effective
than Reticulose, which has not yet been established or proven to be effective as
an anti-viral agent to the FDA's or any other regulatory agency's standards. AVR
is not currently, and there can be no assurances that in the foreseeable future
AVR will be, a significant factor in the pharmaceutical field. Additionally,
small development stage entities, such as AVR, with very limited resources, are
at a very serious disadvantage in attempting to operate in a market against
established Competitors. See "Business -- Competition."

Lack of Patent Protection to Prevent Replication of Reticulose by Competitors.

         AVR does not presently have a patent for Reticulose, however, AVR has
two patents for the use of Reticulose as a treatment (the "Use Patents"), and
has 32 patent applications pending with the U.S. Patent and Trademark Office.
Other companies, having greater economic resources, may be successful in
developing a similar product. AVR has retained patent counsel for the purpose
pursuing additional patent protection for Reticulose. However, there is no
certainty that patents will be granted, or if granted, that the patents will be
sustained if judicially attacked, and, if declared valid, that the patents, in
fact, will operate to protect AVR from others copying Reticulose.



                                       7

Risk of Adverse Product Liability Claims and Lack of Product Liability
Insurance.

         AVR, like any pharmaceutical manufacturer, could be subjected to claims
for adverse reactions resulting from the use of Reticulose. Although AVR is
unaware of any such claims or threatened claims since Reticulose was initially
marketed in the 1940's, one study noted adverse reactions in guinea pigs. In the
event any claims for substantial amounts were successful, they could have a
material adverse effect on AVR's financial condition and on the marketability of
Reticulose. As of the date hereof, AVR does not have product liability
insurance. AVR has not allocated any portion of the proceeds that it may receive
upon the exercise of any options or warrants, of which there can be no
assurance, to the cost of product liability insurance. There can be no assurance
that AVR would be able to secure such insurance in adequate amounts, at
reasonable premiums, if it determined to do so. Should AVR be unable to secure
product liability insurance, the risk of loss to AVR in the event of claims
would be greatly increased and could materially adversely affect AVR.

Significant Outstanding Convertible Securities.

         As of the date of this prospectus, in addition to the 301,340,183
shares of AVR common stock outstanding, there were outstanding (i) the Options,
which are exercisable into an aggregate of 27,765,415 shares of common stock at
exercise prices ranging from $0.11 to $0.36; (ii) the Warrants, which are
exercisable into 5,451,922 shares of common stock; and (iii) the 1998 Debenture
(currently estimated to be convertible into an aggregate of approximately
9,057,971 shares based upon the market price of the common stock on the date of
this prospectus: $0.22).

            If all the Options, Warrants, and the 1998 Debenture were fully
exercised and converted, as the case may be, there would be outstanding
343,615,491 shares of common stock, all of which would be available for public
resale. The sale or availability for sale of this number of shares of common
stock in the public market could adversely affect the market price of the common
stock. Additionally, the availability to AVR of additional equity financing, and
the terms of any such financing, may be adversely affected by the sale or
availability for sale of this number of shares.

Reliance Upon Officers and Key Personnel.

         AVR is currently wholly dependent upon the personal efforts and
abilities of its three full-time executive officers, only one of whom, Bernard
Friedland, Chairman of the Board, has any experience in the pharmaceutical
industry. The loss or unavailability to AVR of the services of Bernard Friedland
or Shalom Z. Hirschman, M.D., President and Chief Executive Officer, could have
a material adverse effect on AVR's business prospects and any potential earning
capacity, and, therefore, AVR has obtained "key-man" insurance on the lives of
Mr. Friedland and Dr. Hirschman in the amounts of $400,000 and $1,000,000,
respectively. In the event AVR's level of operations shall significantly
increase, the business may depend upon its abilities to attract and hire
additional management and staff employees. There can be no assurance that AVR
will be able to secure such additional management and staff, if necessary. See
"Management --

Executive Officers and Directors" for further information concerning the extent,
nature and scope of management's business experience.

Voting Control by Present Management.

         As of the date of this prospectus, the current officers and directors
of AVR beneficially owned 91,671,133 shares of common stock of AVR or
approximately 29% of the 301,340,183 shares of common stock deemed outstanding
on that date for the purposes of the percentage calculation, including certain
shares underlying options held by Shalom Z. Hirschman. As there are no
cumulative voting rights, current members of management, by virtue of their
stock ownership, can be expected to influence substantially the election of all
of the directors of AVR and thereby continue to impact substantially AVR's
business, affairs and policies. See "Principal Shareholders" and "Description of
Securities."

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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

OVERVIEW

         Since its inception in July 1985, AVR has been engaged primarily in
research and development activities. AVR has not yet generated significant
operating revenues, and as of December 31, 1998 AVR had incurred a cumulative
net loss of $12,978,059. AVR's ability to generate substantial operating revenue
depends upon its success in gaining FDA approval for the commercial use and
distribution of Reticulose. All of AVR's research and development efforts have
been devoted to the development of Reticulose.

         In order to commence clinical trials for regulatory approval of
Reticulose in the United States, it will be necessary for AVR to prepare and
file a new IND with the FDA. Filings with foreign regulatory agencies will be
required to continue or begin new clinical trials overseas. Within the next 12
months, AVR presently intends to submit a new IND to the FDA seeking approval to
conduct a study testing the efficacy of Reticulose on human subjects with AIDS,
as well as other interferon related viruses, which AVR believes will address the
deficiencies noted in the FDA's prior correspondence to AVR regarding
Reticulose. In the new IND, AVR presently intends, among other things, (i) to
establish that the proposed formulation of Reticulose is the same as the
formulation of Reticulose referenced in cited publications; (ii) to include
relevant information on the chemistry, laboratory and animal controls to assure
the integrity of the dosage form; (iii) to include safety information for the
initial study proposed to be conducted on humans; (iv) to include information
assuring the proper identification, quality, purity and strength of Reticulose
and a description of the physical, chemical and microbiological characteristics
of Reticulose; and (iv) to submit data supporting in vitro anti-HIV activity, or
other criterion for a biological response modifier. AVR believes that the new
IND will demonstrate the low incidence of adverse events in the use of
Reticulose for the treatment of AIDS and other interferon related viruses.
However, the FDA will make its own evaluation of the clinical trial data and
there is no assurance that the FDA will approve AVR's IND. Because AVR is only
at the preliminary stages of its efforts with regard to the new IND, it is
impossible to determine whether the data from any ongoing studies will be able
to be used by AVR in connection with the new IND or if the new IND will ever be
approved by the FDA. FDA approval to begin human clinical trials of Reticulose
will require significant cash expenditures, the amount of which is not currently
determinable. Further, there can be no assurance that Reticulose will ever be
approved for commercial distribution by any country.

         In addition to developing clinical trial programs, AVR plans to
continue to provide funding for its laboratory testing programs at selected
universities, medical schools, laboratories and hospitals for the purpose of
testing the efficacy of Reticulose, but the amount of research that will be
conducted at those institutions will depend upon AVR's financial status. Because
AVR's research and development expenses and clinical trial expenses will be
charged against earnings for

                                       15

financial reporting purposes, management expects that losses from operations
will continue to be incurred for the foreseeable future.

RESULTS OF OPERATIONS

         During the fiscal years ended December 31, 1998 and 1997, AVR incurred
losses of $3,984,793 and $4,141,729, respectively, compared to $1,154,740 in
1996. AVR's increased losses for the fiscal years ended December 31, 1998 and
1997 as compared with the fiscal year ended December 31, 1996 were attributable
primarily to the salary of Shalom Z. Hirschman, M.D. as President and Chief
Executive Officer of AVR, interest charges as a result of the beneficial
conversion feature associated with the 1997 Debentures (as defined below),
increased research and development expense, opening and maintenance costs of
AVR's Yonkers, NY office, and the implementation of Statement of Financial
Accounting Standards Board (SFAS) No. 123, "Accounting for Stock-Based
Compensation," which accounted for options granted and recorded as compensation
expense. Administrative expenses and the lack of sales revenues also contributed
to AVR's losses.

         There were $656 and $2,278 in sales revenues in 1998 and 1997,
respectively, compared to $24,111 in sales revenues for 1996. All sales revenues
resulted from distributors purchasing Reticulose for testing purposes. Interest
income was $102,043 and $111,845 in 1998 and 1997, respectively, compared to
$46,796 in 1996. In 1998 and 1997, AVR collected $0 from the sale of territorial
rights compared to $32,000 in 1996.

         There can be no assurance that Reticulose will ever be commercially
distributed anywhere in the world.

LIQUIDITY

         As of December 31, 1998, AVR had current assets of $1,795,014, compared
to $3,260,930 at December 31, 1997. AVR had total assets of $3,304,953 and
$4,189,842 at December 31, 1998 and 1997, respectively. The decrease in current
and total assets was primarily attributable to the use of investment capital to
fund increased operating expenditures.

         During 1998, AVR used cash of $3,364,528 for operating activities, as
compared to $2,179,780 in 1997 and $665,682 in 1996. During 1998, AVR (i)
incurred non-cash expenses of approximately $230,000 and $285,000, respectively,
relating to amortization of loan costs and discount on warrants relating to the
1997 Debentures; (ii) incurred non-cash expenses of approximately $667,000
relating to amortization of deferred interest; (iii) expended approximately
$316,000 in legal and consulting fees; (iv) expended approximately $210,000 in
laboratory supplies; (v) expended approximately $1.1 million for payroll and
related costs; and (vi) obtained approximately $1.3 million in proceeds from the
sale of the 1998 Debenture. During 1998, AVR expended approximately $675,000 for
leasehold improvements and furniture and equipment at AVR's Yonkers, New York
office.

<PAGE>

         During 1998, cash flows provided by investing activities was primarily
due to the sales of investments which were available from the proceeds of the
issuance of the convertible debentures in 1997. AVR also acquired property and
equipment for its New York laboratory. See "Capital Resources" for a discussion
of cash flows provided by financing activities.

         AVR's independent certified public accountants' report on AVR's
consolidated financial statements for the fiscal year ended December 31, 1998,
includes an explanatory paragraph regarding AVR's ability to continue as a going
concern. Note 2 to the Consolidated Financial Statements stating that AVR's
ability to continue operations is dependent upon its continued sale of its
securities for funds to meet its cash requirements, which factors raise
substantial doubt about AVR's 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. AVR has no immediate plan to issue any
securities, otherwise than upon the possible exercise of the Options, the
Warrants, or the conversion of the 1998 Debenture.

CAPITAL RESOURCES

         AVR has been dependent upon the proceeds from the continued sale of
securities for the funds required to continue operations at present levels and
to fund further research and development activities. The following table
summarizes the securities sold by AVR since February 1997.

         Debentures and Warrants Issued in 1997.

         In February 1997 and October 1997, in order to finance research and
development, AVR 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 "1997 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 AVR 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 AVR, $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 shares of common stock,
respectively. As of May 5, 1998, the October Debenture was fully converted.

         In connection with the issuance of the 1997 Debentures, AVR issued to
RBB six warrants (the "1997 Warrants") to purchase common stock, three of such
warrants entitling the holder to purchase, from February 21, 1997 through
February 28, 2007, 178,378 shares of the common stock, and three of such
warrants entitling the holder to purchase, from August 30, 1997 through August
30, 2007, 600,000 shares of the common stock. The exercise prices of the 1997
Warrants are $0.288, $0.576, $0.864, $0.20, $0.23 and $0.27 per warrant share,
respectively. Each 1997 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 1997 Warrant as the excess of the market value of shares of
common stock over the warrant exercise price bears to that market value. Each
1997 Warrant contains anti-dilution provisions which provide for the adjustment
of warrant price and warrant shares as more particularly set forth therein. As
of March 24, 1999, none of the 1997 Warrants have been exercised.

         Debentures and Warrants Issued in 1998.

         In November 1998 AVR sold $1,500,000 principal amount of its 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 (the "1998 Debenture"). Accrued interest under the 1998
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 1998 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 1998 Debenture
is subject to adjustment and could be materially less or more than


                                       18
<PAGE>

the above estimated amount, depending upon factors that cannot be predicted by
AVR at this time, including, among others, the future market price of the common
stock.

         Based on the terms for conversion associated with the 1998 Debenture,
there is an intrinsic value associated with the beneficial conversion feature of
$625,000. This amount has been treated as deferred interest expense and recorded
as a reduction of the convertible debenture with a corresponding credit to
additional paid-in capital and is being amortized to interest expense over a one
year period beginning November 16, 1998, based on management's expectation of
when complete conversion will occur. The interest expense relative to this item
was $52,083 for 1998.

         In connection with the issuance of the 1998 Debenture, AVR issued to
RBB two warrants to purchase common stock , each warrant entitling the holder to
purchase, until October 31, 2008, 375,000 shares of the common stock. The
exercise prices of the two warrants are $0.20 and $0.24 per warrant share,
respectively. Each warrant provides that the holder may elect to receive a
reduced number of shares of common stock on the basis of a cashless exercise;
that number of shares bears the same proportion to the total number shares
issuable under that warrant as the excess of the market value of shares of
common stock over the warrant exercise price bears to that market value. Each
warrant contains anti-dilution provisions which provide for the adjustment of
warrant price and warrant shares as more particularly set forth therein. As of
April 24, 1999, none of such warrants had been exercised.

         The fair value of the warrants issued in connection with the 1998
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
has been reflected in the accompanying consolidated financial statements as
interest expense related to the 1998 Debenture.

         Under the terms of the RBB agreement, AVR is required to file with the
Commission this registration statement to register shares of the common stock
issuable upon conversion of the 1998 Debenture and upon exercise of the related
warrants to allow the investors to resell such common stock to the public.
Because this registration statement was not declared effective by the Commission
on or before April 13, 1999, AVR is obligated under the RBB agreement to pay RBB
a penalty equal to the sum of (x) $30,000 and (y) $1,500 for each day lapsed
after such date, until this registration statement is declared effective by the
Commission, provided, however, that total penalties shall not exceed $100,000 in
the aggregate.

         In December 1998 pursuant to a securities purchase agreement, AVR sold
4,917,276 shares of common stock, and warrants to purchase an aggregate of
2,366,788 shares of common stock, including (x) two warrants to purchase an
aggregate of 1,966,788 shares of common stock and (y) a finder's fee paid to
Harborview 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
which $600,000 was received on December 31, 1998, and $202,500 was received in
January 1999. Two of the warrants entitle the holders thereof to purchase
983,394 and 983,394 shares of common stock at exercise prices of $0.2040 and
$0.2448 per share, respectively. The other two warrants entitle the holders
thereof to purchase 200,000 and 200,000 shares of common stock at exercise
prices of $0.2040 and $0.2448


                                       19
<PAGE>

per share, respectively. All four 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 more particularly set forth
therein. As of April 24, 1999, none of such warrants had been exercised.

         Under the terms of the purchase agreement, AVR is required to file with
the Commission this 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 purchase agreement further
provides that, in the event this registration statement is not declared
effective by the Commission on or before May 21, 1999, AVR is required to pay a
penalty of $30,000 for each full calendar month or portion thereof lapsed after
such date, until this registration statement is declared effective, provided,
however, that total penalties shall not exceed $100,000 in the aggregate.

         The fair value of the warrants issued as of January 7, 1999, the date
of issuance of the shares underlying the securities purchase agreement in
connection with the aforementioned transaction 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.

         Research and Development Expenditures in 1998.

         In February 1998, AVR entered into that certain Concurrent Agreement
with DCT, an Argentine corporation, whereby AVR agreed to provide DCT or its
assignees up to $412,960 to cover the costs of a study on 65 patients to compare
the results of treatment of AIDS patients using a three-drug cocktail and
Reticulose versus AIDS patients taking a three-drug cocktail and a placebo. As
of December 31, 1998, AVR has advanced approximately $50,000 for this study,
which has been accounted for as research and development expense. In May 1998,
AVR entered into the Rheumatoid Arthritis Agreement with DCT whereby AVR agreed
to provide DCT or its assignees up to $94,950 to cover the costs of a controlled
study in 30 patients to determine the efficacy of Reticulose for the treatment
of rheumatoid arthritis in humans. In connection with this study, as of December
31, 1998, AVR has advanced approximately $79,200 which has been accounted for as
research and development expenses. In July 1998, AVR authorized the expenditure
of up to $90,000 to study the effects of Reticulose in inhibiting the mutation
of the AIDS virus on patients in Buenos Aires, Argentina. As of December 31,
1998, AVR had advanced approximately $55,000 for such studies, which have been
accounted for as research and development expense.

         If the FDA or other approvals are obtained, of which there can be no
assurance, funds must be budgeted by AVR from the exercise of options and
warrants, potential grants and/or additional equity, the availability of which
funds there can be no assurance.


                                       20
<PAGE>

         AVR is currently expending approximately $300,000 per month, which
expenses include salaries, rent, professional fees, license fees and taxes,
research and development, and travel, principally between AVR's two offices and
its Bahamian facility, and anticipates that it can continue operations for at
least ten months with its current liquid assets, including the proceeds from the
recent sale of the 1998 Debenture and other securities if no Options or Warrants
are exercised. If all of the Options and Warrants are exercised, AVR will
receive net proceeds of approximately $8.4 million. Those proceeds will
contribute to general and administrative and working capital and will permit AVR
to substantially increase its budget for research and development and clinical
trials and testing and to operate at significantly increased levels of
operation, assuming Reticulose receives approvals and prospects for sales
increase to justify such increased levels of operation, of which there can be no
assurance. 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. However, there can be no assurance that the recent trading
levels will be sustained or that any additional options or warrants will be
exercised. In the event that less than 25% or none of the outstanding options
and warrants are exercised, and no other additional financing is obtained by
AVR, in order for AVR to achieve the level of operations contemplated by
management, management anticipates that it will have to limit intentions to
expand operations beyond current levels. AVR is currently seeking debt
financing, licensing agreements, joint ventures and other sources of financing.
There can be no assurance that such additional sources of financing will be
found. There can be no assurance that any of AVR's distributors will ever obtain
regulatory approvals to test or market Reticulose in any territory. In the event
that financing is not available, in order to continue operations, management
anticipates that they will have to defer their salaries. 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 uncertainties involved in the process of gaining
approval for commercial drug use on humans, no assurance can be given that AVR
will be able to sell Reticulose.

         AVR does not have a patent for Reticulose, although AVR has two patents
for the use of Reticulose as a treatment. In addition, AVR has filed 32 patent
applications with the United States Patent Office. There can be no assurance
that other companies, having greater economic resources, will not be successful
in developing a similar product using processes similar to those of AVR. There
can be no assurance that AVR will obtain such a patent or, if obtained, that it
will be enforceable. AVR has retained patent counsel for the purpose of pursuing
additional patent protection for Reticulose. However, there is no certainty that
patents will be granted, or if granted, that the patents will be sustained if
judicially attacked, and, if declared valid, that the patents, in fact, will
operate to protect AVR from others copying Reticulose. AVR has relied upon laws
protecting proprietary information and trade secrets and upon confidentiality
agreements to protect its rights to Reticulose and the processes for its
manufacture, but there can be no assurance that such efforts and procedures will
continue to be successful and protect AVR from any competition in the future.

YEAR 2000 COMPLIANCE

         The Year 2000 ("Year 2000") computer issue is the result of computer
programs using a two-digit format, as opposed to a four-digit format to indicate
the year. Such computer programs will


                                       21
<PAGE>

be unable to recognize date information correctly when the year changes to 2000.
The Year 2000 issue poses risks for AVR's information technology systems.

         AVR's information technology systems are based upon software licenses
and software maintenance agreements with third party software companies. Based
upon AVR's internal assessments and communications with its software vendors,
all of the software utilized by AVR is Year 2000 compliant software. AVR has
used internal personnel to test its software systems for Year 2000 compliance
and such tests yielded positive results. AVR will continue to monitor its Year
2000 readiness. Also, AVR does not anticipate difficulty in resolving issues
related to imbedded technology in the equipment provided to AVR by other
manufacturers.

         Based on the foregoing, AVR believes that it will be Year 2000
compliant on a timely basis and that future costs relating to the Year 2000
issue will not have a material impact on AVR's consolidated financial position,
results of operations or cash flows.


                                    BUSINESS

OVERVIEW

         Advanced Viral Research Corp. (the "Company" or "AVR") was incorporated
under the laws of the State of Delaware on July 31, 1985 to engage in the
production and marketing, promotion and sale of a pharmaceutical drug with the
trade name "Reticulose." Reticulose has not been approved for sale or use by the
FDA or any foreign government body. AVR is in the developmental stage, and has
not as yet commenced any commercial operations. AVR is dependent on registration
and/or approval by applicable regulatory authorities of Reticulose, of which
there can be no assurance, in order to commence commercial operations.

         AVR's operations over the last five years have been limited principally
to engaging in research, in vitro testing and analysis of Reticulose in the
United States, and engaging others to perform testing and analysis of Reticulose
on human patients overseas. In connection with these engagements, AVR has also
granted distribution rights for Reticulose in certain foreign countries. In
1995, AVR retained Shalom Hirschman, M.D. as its President. Since becoming
President of AVR, Dr. Hirschman has monitored the testing of Reticulose and has
recently performed certain analyses of Reticulose with Company personnel, which
analyses AVR believes may be used in connection with the FDA approval process.

BACKGROUND OF RETICULOSE

         Reticulose had been marketed in the United States during the 1940's
through the early 1960's. However, under the Federal Food, Drug, and Cosmetic
Act, as amended in 1962 (the "1962 Act"), the FDA classified Reticulose as a
"new drug" requiring FDA approval prior to any sale in the United States. A
forfeiture action was instituted in 1962 by the FDA against Reticulose, and
Reticulose was withdrawn from the United States market. The injunction obtained
by the FDA


                                       22
<PAGE>

prohibits any shipment of Reticulose in the United States for treatment purposes
until a New Drug Application ("NDA") for Reticulose is approved by the FDA.

         In 1985, Bernard Friedland, former President and current Chairman of
the Board, and William Bregman, Secretary and Treasurer of AVR, organized AVR
for the purpose of producing Reticulose and seeking approvals for marketing it
world-wide, and thereafter obtained the rights to Reticulose in May 1986. The
FDA has not approved human clinical trials for Reticulose in the United States.
AVR 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, of which there can be no assurance. AVR
does not know what the actual cost of such trials would be. If AVR needs
additional financing to fund such human clinical trials, there can be no
assurance that additional financing will be available to AVR. No assurance can
be given that any IND for clinical tests of Reticulose on humans will be
approved by the FDA for human clinical trials, or that the results of such human
clinical trials will prove that Reticulose is safe or effective in the treatment
of any diseases. Further, there is no assurance that the FDA will ever approve
the sale of Reticulose in the United States.

GOVERNMENT REGULATION; THE INVESTIGATIONAL NEW DRUG APPLICATION
PROCESS

         The FDA imposes substantial requirements upon and conditions precedent
to the introduction of therapeutic drug products, such as Reticulose, 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. Testing in humans may not be commenced until after an IND
exemption is granted by the FDA. A New Drug Application ("NDA") must be
submitted to the FDA for new drugs that have not been previously approved by the
FDA and for new combinations of, and new indications and new delivery methods
for, previously approved drugs.

         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.
The initial IND may cover only Phase I.


                                       23
<PAGE>

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

         When 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 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 human pharmacokinetic data and
human bioavailability data (or information supporting a waiver of the submission
of in vivo bioavailability 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 bioavailability of the drug products


                                       24
<PAGE>

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, former President and current
Chairman of the Board of AVR, as sponsor, submitted to the FDA an IND to conduct
a study testing the efficacy of Reticulose on human subjects with AIDS, as well
as other interferon related 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 AVR
can 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 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, AVR 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. See "Government Regulation; the Investigational New Drug Application
Process."

         On March 6, 1992, AVR submitted an amendment to the IND, which
attempted to address the FDA's concerns. In response to the March 1992
submission, AVR 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 the part
of AVR. In June 1995, AVR received further correspondence from the FDA which
stated, among other things, that AVR's prior submissions to the FDA did not
provide an adequate response to the FDA's earlier request for preclinical
information and accordingly AVR's IND was "inactivated."

         AVR has 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, AVR contracted with GloboMax LLC of Hanover,
Maryland to advise AVR in its preparation of an IND to be filed with the FDA,
and to otherwise assist AVR through the FDA process with the objective of
obtaining full approval for Reticulose in the United States. Pursuant to the
agreement with GloboMax LLC, AVR is obligated to pay for services on an hourly
basis, at prescribed rates. There can be no assurances as to the costs or the
timing of the filing of the new IND or whether AVR has the resources to complete
the FDA approval process. AVR may allocate certain funds from the exercise of
currently outstanding options and warrants for the purpose of filing a new IND
with the FDA,


                                       25
<PAGE>

however, no assurance can be given that any of the currently outstanding options
or warrants will be exercised. No assurance can be given that any new IND for
clinical tests of Reticulose on humans will be approved by the FDA for human
clinical trials on AIDS or other diseases, that any tests previously conducted
or to be conducted will satisfy FDA requirements, that the results of such human
clinical trials will prove that Reticulose is safe or effective in the treatment
of AIDS or other diseases, or that the FDA would approve the sale of Reticulose
in the United States if any application were to be made by AVR. It is not known
at this time how extensive the Phase II and Phase III clinical trials will be,
if they are conducted. There can be no assurances that the data generated will
show that the drug Reticulose is safe and effective and even if the data shows
that Reticulose is safe and effective, obtaining approval of the NDA could take
years and require financing of amounts not presently available to AVR.

         In connection with its activities outside the United States, AVR is
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 Reticulose for a considerable period
of time and impose costly procedures upon AVR's activities. The extent of
potentially adverse government regulations which might arise from future
legislation or administrative action cannot be predicted. Whether or not FDA
approval has been obtained for a product, approval of the product by comparable
regulatory authorities of foreign countries must be obtained prior to marketing
the product in those countries. The approval process may be more or less
rigorous from country to country, and the time required for approval may be
longer or shorter than that required in the United States. No assurance can be
given that clinical studies conducted outside of any country will 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, it is not expected that AVR
will be able to generate material sales revenues. AVR received a grant of
authority from the Bahamian Port Authority on October 15, 1992 confirming the
right of AVR's subsidiary, Advanced Viral Research, Ltd., a Bahamian
corporation, to carry on the manufacture and export sale of ethical
pharmaceutical products. See "-Marketing And Sales" and "-Exclusive Distribution
Agreements."

TESTING AGREEMENTS

                  For the period from inception (February 20, 1984) through
December 31, 1998 AVR expended approximately $2.5 million on testing and
research and development activities.

         Testing in the United States.

         On September 20, 1984, AVR's IND for Reticulose was submitted for a
Phase I type study to determine if there was any pharmacological activity in
humans against HIV. See "Government Regulation; the Investigational New Drug
Application Process." In response to the FDA deficiency letters in 1984 and 1987
regarding AVR's IND, AVR was required among other things, to demonstrate that
AVR's formulation of Reticulose was identical to the formulation reported in the
prior anecdotal history and studies of Reticulose. In response to the deficiency
letters from the FDA,


                                       26
<PAGE>

AVR engaged (i) the University of Wisconsin Biotechnology Center to perform a
series of protein tests for product control and protein fragment identification;
(ii) Southern Research Institute, Birmingham, Alabama and Vironc Laboratories,
North Miami Beach, Florida to perform in vitro screenings of Reticulose against
the HIV virus in two separately conducted independent laboratory screenings; and
(iii) International Diagnostics Ltd. Inc., Dania, Florida, an independent
testing laboratory, to perform standard mouse toxicity assays to demonstrate
toxicity of Reticulose. Management of AVR originally believed that due to the
early safety record and published reports of human use that the FDA would permit
the initial Phase I trials in humans after approximately six months. If
sufficient funds are available from the sale or exercise of securities or other
sources, AVR will consider taking the additional steps to satisfy the FDA that
the formulation of Reticulose is identical to the formulation reported in the
prior anecdotal history and studies. The time and costs required for IND
approval as a result of the FDA not accepting the prior history of the drug is
currently not known to AVR but could be considerable. AVR may file a new IND
with the FDA as opposed to amend its prior IND.

         Topical Safety Study.

         In October 1997, AVR contracted with Chrysalis Preclinical Service
Corporation and Product Investigations, Inc., both unaffiliated third party
laboratories, to conduct testing on animals and cultured human cells to
determine the safety of the topical use of Reticulose, which testing was
completed in November 1998. The studies showed no toxicity for the topical
application of Reticulose. As of December 31, 1998, AVR advanced approximately
$170,000 for such study.

         Canadian Contract.

         During the period from 1992 to 1995, AVR had been seeking approval in
Canada for controlled distribution of Reticulose. AVR submitted an application
for a limited study on 24 patients with Kaposi's Sarcoma, a condition associated
with AIDS, the approval of which application was pending in 1995. However, due
to delay in obtaining the approval for this study and after receiving deficiency
letters from the Health Protection Branch of the Health and Welfare Department
of Canada, AVR withdrew the application to have such study commence.

         Plata Partners Limited Partnership.

         On March 20, 1992, AVR entered into an agreement with Plata Partners
Limited Partnership ("Plata"), a Michigan limited partnership unaffiliated with
AVR (the "Plata Agreement"), pursuant to which Plata agreed at its expense, to
perform a demonstration on ten patients of both sexes from 18 to 45 years of age
for 45 days, without control group, at Campus #1 University C.B.E.P., University
of Santo Domingo, Santo Domingo, Dominican Republic in accordance with a certain
agreed upon protocol (the "Protocol") to assess the efficacy of a treatment
using Reticulose incorporated in the Protocol against AIDS (the
"Demonstration"). The Protocol provides, among other things, that the treatment
consists of Reticulose along with vitamin and protein supplements. The
preliminary and final results of the Demonstration were previously reported by
AVR in its Reports on Form 8-K filed with the Securities and Exchange Commission
("SEC") on July 10, 1992 and November 6, 1992.


                                       27
<PAGE>

         The Demonstration was conducted on the patients from May 1992 through
July 1992. The Demonstration was supervised by Angelo A. Chinnici, M.D., and
administered by medical doctors certified to practice in the Dominican Republic.
A videotape has been produced by Plata memorializing the Demonstration, which
videotape was delivered to AVR in August 1992. On August 12, 1992 AVR received
from Plata a translated written transcript of a press conference (the "Press
Conference") called and conducted by Plata in Santo Domingo, Dominican Republic
on August 7, 1992 (the "Transcript"). The Press Conference was held by Plata
following the completion and the release of preliminary results of the
Demonstration.

         The Transcript, a copy of which has been filed with AVR's Report on
Form 8-K with the Commission on August 14, 1992, provides, among other things,
statements from Dr. Joaquin Perez-Mendez, the Director of the Program for
Control of Sexually Transmitted Diseases (Procets) a governmental organization
in the Dominican Republic, who participated in the administration of the
Demonstration, Dr. Charles Dunlop, then the Surgeon General of the Dominican
Republic, Dr. Norman de Castro and Dr. Rafael Alcantara, who is associated with
the Center for Sexually Transmitted Diseases in the Dominican Republic
(collectively, the "Doctors").

         In the Transcript, the Doctors generally expressed their optimism and
hopefulness regarding Reticulose and they encouraged further testing of the
efficacy of Reticulose against AIDS and efforts to register Reticulose. As of
the date hereof, AVR has not independently verified or otherwise substantiated
the accuracy or completeness of the Transcript or the Press Articles. The
Demonstration conducted by Plata was not a double-blind study. However, to date
no registration certificate has been granted by the Dominican Republic, and
there can be no assurance that such certificate will be issued. Further, AVR is
currently not pursuing the registration certificate in the Dominican Republic.

         AVR has also been made aware that certain newspaper articles appeared
in Spanish language newspapers (published in the Dominican Republic) regarding
the Press Conference (the "Press Articles") and interviews with Drs.
Perez-Mendez and Alcantara, which reported that the preliminary results of the
Demonstration were "very encouraging" and that the "laboratory results
subsequent to the treatment, reveal a more than 50 percent reconversion of the
cell immunological system in almost all of the patients being maintained with
relatively little favorable change in the only patient who did not complete the
treatment." According to certain of the Press Articles, certain of the doctors
attending the Demonstration stated: "Although it [(the Demonstration)] does not
have the representativeness which a study of this caliber requires, precisely
due to the small number of patients involved in the same, and above all due to
the fact that it did not rely on a control group which permits us to make some
significant comparisons, basically it is a good job of research and the results
[are] clearly excellent."

         AVR received from Plata certain written information, certain copies of
which are incorporated by reference into AVR's Reports on Form 8-K delivered for
filing to the Commission on July 10, and July 23, 1992 (the "Plata Statement").
The Plata Statement reports, among other things, certain positive preliminary
results of the Demonstration (the "Results"), including the fact that all
patients showed weight gain, as well as resolution of malaise, joint pain, and
diarrhea and that those patients initially presented with herpetic lesions
showed clearing and well healed vesicles,


                                       28
<PAGE>

there was a decrease in lymphotenopathy in the majority of patients, and their
oral thrush was greatly improved.

         In August 1992, AVR received from Lionel Resnick, M.D., F.A.A.D.,
F.A.C.P., Chief, Retrovirology Laboratories, Departments of Dermatology and
Pathology, Mount Sinai Medical Center of Greater Miami, in Miami, Florida,
written correspondence relating to the Demonstration generally stating that,
based upon his review of the results of the Demonstration, a "dramatic" clinical
improvement was documented over the forty-five day period of the study and there
were significant changes in laboratory surrogate markers consistent with
beneficial drug effects, although he noted that enthusiasm regarding the
Demonstration should be tempered by the lack of a homogeneous study population
and defined clinical endpoints.

         In October 1992, AVR received from Anthony J. Mangia, M.D., certified
by Plata to be an expert in the area of AIDS research, further written
correspondence relating to the Demonstration (the "Mangia Correspondence"). As
an independent observer, Dr. Mangia visited the Demonstration site, reviewed
scientific data regarding the in vitro activity of Reticulose against various
viruses, interviewed the study physicians, examined some of the patients, and
reviewed the written results of the Demonstration. The Mangia Correspondence
basically stated that Reticulose may be an effective alternative treatment for
AIDS patients, based on a review of the data provided, that the results of the
Demonstration appear to indicate that Reticulose is tolerated well, with no
significant adverse reactions. The Mangia Correspondence also indicated that the
patients Dr. Mangia examined had experienced an improvement in symptoms and a
sense of well being by the time the Demonstration had concluded.

         The Mangia Correspondence does, however, contain several criticisms of
the Demonstration, including, among other things, the brevity of the
Demonstration, the lack of stratification according to CD 4 count, the small
number of subjects, the inclusion of nutritional supplements along with the
Reticulose, and the lack of pre- and post-treatment weights and performance
status evaluation of the subjects. The Mangia Correspondence concluded that the
results of the Demonstration appear to indicate that further studies in animals
and humans appear to be warranted, and suggested that such further studies need
to be better controlled and performed on a larger scale with more sophisticated
methods than the Demonstration.

         AVR received from Plata a copy of a report dated September 30, 1992,
from Angelo A. Chinnici, M.D. regarding the Demonstration (the "Chinnici
Report"), with respect to the hypothesis, objectives, methodology, clinical
tracking and procedures involved in the Demonstration. Among other things, the
Chinnici Report noted that the majority of the subjects involved experienced a
dramatic clinical improvement, such as reduction in oral thrush, reduction in
herpetic lesions, and improvement in certain dermatological conditions such as
seborrheic dermatitis and eczema. The most dramatic change was observed in the
number of CD 4 and CD 8 lymphocytes, as well as in the CD 4 and CD 8 ratio,
where nine of the ten patients experienced an increase in the CD 4 cells. The
Chinnici Report further noted that the administration of Reticulose, among other
things, produced no adverse side affects, significant anemia, nor any decrease
in the subjects' white blood cell count, may cause a halt to viral replication
and may produce endogenous interferon, which improves a patient's condition.
However, The Chinnici Report also indicated, among other things, that the


                                       29
<PAGE>

Demonstration was limited in that the subjects were treated for a short period
of time and there was no control group. AVR has not independently verified any
of the statements contained in either the Mangia Correspondence or the Chinnici
Correspondence.

         AVR believes the Demonstration will not significantly impact the FDA's
decision to (i) approve an IND filed with the FDA or (ii) approve of the
marketing, sales or distribution of Reticulose within the United States.
Further, AVR believes the Demonstration will not significantly impact AVR's
ability to obtain approval for the marketing, sales or distribution of
Reticulose anywhere in the world.

         Pursuant to the Plata Agreement, AVR authorized the issuance to Plata
of 5,000,000 shares of common stock and options to purchase an additional
5,000,000 shares at $0.08 per share through July 9, 1994 (the "Plata Options")
and 5,000,000 shares at $0.10 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 April 30, 1999 at an exercise
price of $0.14 and $0.16, respectively. As of December 31, 1998, there are
outstanding Plata Options to acquire 683,300 shares at $0.14 per share and
Additional Plata Options to acquire 108,100 shares at an exercise price of $0.16
per share. Through December 31, 1998, AVR 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.

         Argentina Agreements.

         On December 27, 1993, AVR entered into an agreement with Juan Carlos
Flichman, M.D., then the Permanent Advisor to the Argentine Association Against
Sexually Transmitted Diseases, whereby Dr. Flichman agreed to conduct a double
blind study of Reticulose in Argentina of (i) 40 patients who have been
diagnosed with acute Hepatitis "B" and (ii) 20 patients diagnosed with Hepatitis
"C" (the "Argentina Study"). The treatment of acute Hepatitis "B" patients was
expected to last for approximately 20 days, followed by a 60/90 day observation
period and of Hepatitis "C" patients was expected to last for 180 days, also
followed by a 60/90 day observation period. Dr. Flichman, however, indicated to
AVR that the Argentina Study was delayed because of the failure to gain
regulatory approval in Argentina to commence testing. The Argentina Study was
never completed.

         In April, 1996, AVR entered into an agreement (the "1996 Agreement")
with DCT S.R.L., an Argentine corporation ("DCT"), pursuant to which DCT and Dr.
Flichman each agreed to conduct open label clinical trials of Reticulose on the
human papilloma virus (HPV) at two separate hospitals located in Buenos Aires,
Argentina (the "HPV Clinical Trial"). In June, 1994, AVR entered into an
exclusive distribution agreement with DCT, whereby AVR granted to DCT, subject
to certain conditions precedent, the exclusive right to market and sell
Reticulose in certain South American countries, including Argentina and other
MERCOSUR States; this agreement was superseded by another exclusive distribution
agreement as of April 1, 1996. Pursuant to the 1996 Agreement, the HPV Clinical
Trial commenced and is being conducted pursuant to a protocol developed by Dr.
Flichman. The purpose of the HPV Clinical Trial is to assess the efficacy of
Reticulose on HPV. The protocol calls for, among other things, a study to be
performed with clinical and laboratory follow-up


                                       30
<PAGE>

on 20 patients between the ages of 18 and 50 years of age. The HPV Clinical
Trial was not a double-blind study and did not include a placebo control group
or reference to any other anti-viral drug.

         Pursuant to the 1996 Agreement, AVR paid approximately $34,000 to DCT
to cover out of pocket expenses associated with the HPV Clinical Trial. The 1996
Agreement further provides that, at the conclusion of the HPV Clinical Trial,
DCT shall cause Dr. Flichman to prepare and deliver a written report to AVR
regarding the methodology and results of the HPV Clinical Trial (the "HPV
Report"). On April 22, 1996, AVR was informed by DCT that the HPV Clinical Trial
had commenced on April 15, 1996. In September 1996, AVR received from Dr.
Flichman the HPV Report. The HPV Report stated that when Reticulose was applied
topically to 20 patients (six males and 14 females) diagnosed to be infected
with HPV, two of the 20 patients had total remissions and eight of the 20
patients experienced clinical improvement ranging from a reduction in color
intensity, size and texture. Further, the HPV Report provides that no adverse
side effects were observed in any of the 20 patients and only one patient
experienced redness of the skin that disappeared spontaneously within 24 hours.

         Upon delivery of the HPV Report to AVR, AVR delivered to the principals
of DCT common stock purchase options (the "DCT Options") to acquire 2,000,000
shares of AVR's common stock for a period of one year from the date of the
delivery of the HPV Report, at an exercise price of $0.20 per share. Pursuant to
several amendments, the DCT options are now exercisable through April 30, 1999
at an exercise price of $0.21 per share. As of December 31, 1998, 464,000 shares
of common stock were issued pursuant to the exercise of these options for an
aggregate exercise price of approximately $93,000. Additionally, in April 1998,
10,000 shares were issued in connection with the exercise of options at $0.20
per share.

         In June 1994, DCT and AVR entered into an exclusive distribution
agreement whereby AVR granted to DCT, subject to certain conditions, the
exclusive right to market and sell Reticulose in Argentina, Bolivia, Paraguay,
Uruguay, Brazil, and Chile (the "DCT Agreement"). During the quarter ended June
30, 1997, AVR entered into an agreement with DCT (the "HIV-HPV Agreement")
whereby AVR 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 Reticulose for the treatment of persons
diagnosed with the HIV virus (AIDS) and HPV (the "HIV-HPV Study"). The HIV-HPV
Agreement provides that (i) in the event the data from the HIV-HPV Study is used
in connection with Reticulose being approved for commercial sale anywhere within
the territory granted under the DCT Agreement or (ii) DCT receives financing to
cover the costs of the HIV-HPV Study, then DCT is obligated to reimburse AVR for
all amounts expended in connection with the HIV-HPV Study. As of December 31,
1998, AVR has advanced approximately $665,000 in connection with the HIV-HPV
Agreement, which is accounted for as a research and development expense. The
amounts have been used to cover expenses associated with clinical activities of
the HIV-HPV Study.

         In October 1997, AVR entered into two agreements with DCT whereby AVR
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


                                       31
<PAGE>

topical application of Reticulose for the treatment of persons diagnosed with
Herpes Labialis/Genital Infections (the "Herpes Study") and HPV (the "HPV
Topical Study"). In connection with the Herpes Study and the HPV Topical Study,
as of December 31, 1998, AVR has advanced approximately $58,000 and $132,500,
respectively, and such expenses are accounted for as research and development
expenses. 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 Reticulose being approved for commercial
sale anywhere within the territory granted under the DCT Agreement or (ii) DCT
receives financing to cover the costs of the studies, then DCT is obligated to
reimburse AVR for all amounts respectively expended in connection with the
Studies.

         In February 1998, AVR entered into an agreement with DCT (the
"Concurrent Agreement") whereby AVR agreed to provide DCT or its assignees, up
to $412,960 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 Reticulose
with those taking a three drug cocktail and a placebo. As of December 31, 1998,
AVR has advanced approximately $50,000 for such study which has been accounted
for as research and development expense.

         In May 1998, AVR entered into an agreement with DCT (the "Rheumatoid
Arthritis Agreement") whereby AVR agreed to provide DCT or its assignees, up to
$94,950 to cover the costs of a controlled study in 30 patients to determine the
efficacy of Reticulose for the treatment of rheumatoid arthritis in humans. In
connection with this study, as of December 31, 1998, AVR has advanced
approximately $79,200 which has been accounted for as research and development
expense.

         In July 1998, AVR authorized the expenditure of up to $90,000 to study
the effects of Reticulose in inhibiting the mutation of the AIDS virus on
patients in Buenos Aires, Argentina. As of December 31, 1998, AVR had advanced
approximately $55,000 for such studies, which have been accounted for as
research and development expense.

         Hirschman Study.

         AVR in late 1995 issued a grant of $30,188 to the Mount Sinai School of
Medicine, New York City, New York, for a study to be conducted by Shalom Z.
Hirschman, M.D., then Professor of Medicine and Director of the Division of
Infectious Diseases of Mount Sinai School of Medicine, for the purpose of
studying the mechanism, if any, by which Reticulose inhibits replication of HIV.
(the "Hirschman Study"). The results of this research demonstrated that
Reticulose stimulates the production of a unique set of chemokines, including
Interleukin 1 (IL-1), Interleukin 6 (IL-6), Gamma Interferon and Tumor Nacrosis
Factor, and inhibits the replication of HIV in cell cultures. were presented by
Dr. Hirschman at Biomedicine '96, the annual meeting (sponsored by SCIENCE, a
journal of the American Association for the Advancement of Science) of the
Association of American Physicians, American Society for Clinical Investigation,
and American Federation for Clinical Research, held May 4-6, 1996, in
Washington, D.C. The manuscript of Drs. Hirschman and Chey Wei Chen, entitled
"Peptide Nucleic Acids Stimulate Gamma Interferon and Inhibit the Replication of
the Human Immunodeficiency Virus," was published in Clinical Research (the
official


                                       32
<PAGE>

compendium of the proceedings of the meeting) in the August 1996 issue of
Journal of Investigative Medicine, a publication of the American Federation for
Clinical Research.

         Barbados Study.

         The first stage of a double-blind, randomized, placebo-controlled
clinical trial using Reticulose in the treatment of AIDS conducted at the Queen
Elizabeth Hospital, Bridgetown, Barbados was completed in late November 1996
(the "Barbados Study"). AVR received a letter from one of the scientists
conducting the Barbados Study dated November 26, 1996 reporting the results of
the first stage of a double-blind, randomized, placebo-controlled clinical trial
using Reticulose in the treatment of patients with AIDS, and confirming that the
study protocol received ethical approval from the Chief Medical Officer's
committee. In this first stage of the clinical trial, 43 patients who had never
previously received any anti-retroviral therapy were enrolled into the study, 21
of which received Reticulose and 22 of which received placebo, over a 60-day
period. The patients were observed for a further sixty days after the cessation
of therapy. At the end of the 60-day treatment period, the key results included
a 37% increase in the mean CD(4)-positive T-cell lymphocytes in the group of
patients that received Reticulose, as compared to a 7% decrease in the group of
patients that received placebo, and a 21% average decrease in HIV viral load, as
measured by quantitative RNA PCR, in the Reticulose-treated group of patients,
in contrast to a 33% increase in HIV viral load in the group of patients that
received placebo. In addition, the letter reported, among other things, that at
the end of the 60-day observation period following cessation of treatment, a
majority of Reticulose-treated group showed a greater rise in blood hemoglobin,
and maintained or increased their body weight in contrast to only a minority of
the placebo-treated patients. Finally, there were no toxic side effects observed
by physicians or reported by patients receiving Reticulose therapy in the first
stage of the trial. An abstract entitled "Controlled Clinical Trial of
Reticulose, a Peptide Nucleic Acid with Immunomodulator Activity in Patients
with HIV Infection" (the "Barbados Abstract") which describes the results of the
first stage of the Barbados Study, was accepted for publication by The American
Society for Microbiology. As of December 31, 1998, AVR has expended
approximately $365,000 to cover the costs of the Barbados Study. Based on
information received from the coordinators of the Barbados Study, AVR is
uncertain as to the costs to be incurred in connection with the Barbados Study
and has not been informed as to when further results from the Barbados Study
will be forthcoming.

         In connection with the Barbados Study, in July 1998, AVR authorized
additional expenditures of up to $45,000 to Queen Elizabeth Hospital,
Bridgetown, Barbados to study the effects of Reticulose in inhibiting the
mutation of the AIDS virus. As of December 31, 1998, AVR has advanced
approximately $10,000 for such study which has been accounted for as research
and development expense.

         National Cancer Institute Study.

         In March 1997, AVR entered into a Material Transfer Agreement -
Cooperative Research and Development Agreement (the "NCI Agreement") with
certain governmental agencies (including the FDA) represented by The National
Cancer Institute (collectively, the "Government Agencies"). The purpose of the
NCI Agreement is for Dr. Howard Young, Section Chief, Laboratory of


                                       33
<PAGE>

Experimental Immunology, Division of Basic Sciences, The National Cancer
Institute, to determine the molecular mechanism by which Reticulose may
specifically enhance transcription of the gamma interferon gene. AVR intends to
supply Reticulose to the Government Agencies for the purpose of research by the
Government Agencies in accordance with a research plan attached to the NCI
Agreement, subject to the conditions stated in the NCI Agreement. The NCI
Agreement provides for non-disclosure by the Government Agencies and an
understanding that AVR and the Government Agencies will enter into licenses to
one another on terms to be negotiated in the future, in the event the research
produces an invention. Either AVR or the Government Agencies may terminate the
NCI Agreement upon 30 days prior written notice to the other. The NCI Agreement
states that the Government Agencies "[do] not directly or indirectly endorse any
product or service provided, or to be provided, whether directly or indirectly
related to either this [agreement] or to any patent or other intellectual
property license or agreement which implements this [agreement] by its
successors, assignees, or licensees. The [Company] shall not in any way state or
imply that this [agreement] is an endorsement of any such product or service by
the U.S. Government or any of its organizational units or employees." Pursuant
to an agreement dated March 19, 1998, the NCI Agreement has been extended for an
additional one year period and provides for the continued study of the basic
mechanisms of immune responses, the investigation of anti-tumor activity of
Reticulose and its effect on rheumatoid arthritis.

MARKETING AND SALES

         Except for limited sales ($656 in 1998) of Reticulose for testing and
other purposes, Reticulose is not sold commercially anywhere in the world. As of
the date of this prospectus, the efforts of AVR or any of its representatives
have produced no material benefits to AVR regarding AVR's ability to have
Reticulose sold commercially anywhere in the world. AVR has entered into
Exclusive Distribution Agreements with five separate entities whereby AVR has
granted exclusive rights to distribute Reticulose 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 Reticulose to be approved for commercial
sale in such countries and upon such approval, to purchase from AVR certain
minimum quantities of Reticulose to maintain the exclusive distribution rights.
The marketing plans of AVR for Reticulose are still dependent upon registration
of Reticulose for sale in the various jurisdictions where its distributors are
seeking approvals. See "-Exclusive Distribution Agreements."

         There can be no assurance that AVR or any distributor will ever secure
registration of Reticulose and AVR to date has received no information that
would lead it to believe that it will be positioned to sell Reticulose
commercially anywhere in the world in the immediate future. To date, the only
application for registration of Reticulose which has been filed is an
application requesting that Reticulose be permitted to be sold in Argentina,
which was filed in March 1998. Notwithstanding the filing of this application,
no material progress has been made to secure approval to sell Reticulose in
Argentina in that AVR is awaiting the results of a test requested by the
government of Argentina which will demonstrate the effect of Reticulose on
certain animals. AVR initially targeted its 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


                                       34
<PAGE>

Influenza, Viral Pneumonia, Virus Infectious Hepatitis, Mumps, Encephalitis,
Herpes Simplex and Herpes Zoster. Those countries included Singapore, Hong Kong,
Malaysia, Taiwan, the Philippines and Malta. Registration of Reticulose 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 Reticulose for sale in these countries has been frustrated due
to AVR's inability to obtain the registration and approval to sell Reticulose in
the Bahamas, the country of origin, and a general lack of published data on the
efficacy of Reticulose. Until Reticulose is registered and approved for sale in
the United States, in another developed country or in the other countries
included in the distributors' territories, there can be no assurance that AVR
will generate any sales of Reticulose. For the years ended December 31, 1998,
1997 and 1996, AVR reported no commercial sales except limited sales for testing
purposes ($656, $2,278, and $24,111, respectively). Reticulose is not legally
available for use anywhere in the world, except for testing purposes and the
FDA's compassionate use program. See "-Testing Agreements."

COMPETITION

         There are inherent difficulties for any development stage company
seeking to enter an established field, particularly in a field so capital
intensive as the manufacture and sale of pharmaceuticals. AVR, if it is ever
successful in securing FDA or other regulatory approvals, will encounter intense
competition engaged in the development and marketing of drug products, all of
which are substantially larger, possess far greater capital assets, have
substantial operating histories and records of successful operations, greater
financial and other resources, more employees and far more extensive facilities
than AVR now has or will have in the foreseeable future. Accordingly, such
companies are in a far better position to compete than AVR. Moreover, such
companies may succeed in discovering, developing and marketing anti-viral
products that are more effective than Reticulose. AVR at present is not, and
there can be no assurances that AVR will become in the foreseeable future, a
significant factor in the field in which it proposes to engage. Additionally,
small "start-up" firms, such as AVR, with very limited resources, are at a very
serious competitive disadvantage against established companies. AVR hopes to
compete, however, based on cost and the effectiveness of Reticulose.

EMPLOYEES

         AVR has 24 full-time employees, consisting of its three executive
officers, 17 employees involved in research, and four administrative employees.
Shalom Z. Hirschman, M.D., President and Chief Executive Officer and a Director
of AVR, Bernard Friedland, Chairman of the Board and a Director of AVR, and
William Bregman, Secretary, Treasurer and a Director of AVR, each devote all of
their business time to the day-to-day business operations of AVR.

         Additionally, AVR 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."

EXCLUSIVE DISTRIBUTION AGREEMENTS

         Agreement with DCT S.R.L.

         Under an Exclusive Distribution Agreement, dated June 1994, superseded
by another agreement, dated April 1, 1996, between AVR and DCT, AVR granted to
DCT subject to certain conditions precedent, the exclusive right to market and
sell Reticulose within the territories of Argentina, Bolivia, Paraguay, Uruguay,
Brazil and Chile (the "DCT Agreement"). The term of the DCT Agreement was for a
three-year period with additional three-year renewal terms from the date DCT
obtained all approvals, licenses, permits and registrations (collectively, the
"Approval") to import and distribute Reticulose in Argentina, subject to DCT's
right to extend the DCT Agreement so long as DCT was diligently pursuing the
Approval and meeting certain annual minimum purchase requirements as set forth
in the DCT Agreement, in the event the Approval for Argentina was obtained. DCT
was granted an option to purchase for a period of one year from the date of
Approval, 2,000,000 shares at a purchase price of $0.20 per Share (the "DCT
Option"). The Approval has not been obtained to date. AVR has not terminated the
DCT Agreement because AVR has not identified another source it believes will be
more successful in obtaining the Approval.

         As a result of the 1996 Agreement, discussed under "-TESTING
AGREEMENTS-Argentina Agreements" and the Health Ministry's approval for and the
commencement of the test of Reticulose on HPV and HIV patients, AVR agreed that
the DCT Option became exercisable.

         Termination of Agreements with C.U.R.E.

         On April 25, 1994, AVR entered into an Exclusive Distribution Agreement
with C.U.R.E. pursuant to which C.U.R.E. was granted exclusive rights to
distribute Reticulose within the countries of China, Japan, Thailand, Singapore,
Hong Kong, Taiwan and Malaysia the ("C.U.R.E. Territory").

         The Exclusive Distribution Agreement with C.U.R.E. was for an initial
term of five years, subject to certain automatic extensions if C.U.R.E.
satisfied its minimum purchase obligations and obtained approval for one or more
countries constituting the C.U.R.E. Territory, within one year from the
Agreement. Because of its failure to obtain any approval, AVR terminated the
rights of C.U.R.E. under this agreement.

         As of June 1, 1994, AVR had also entered into an Exclusive Distribution
Agreement with C.U.R.E. Pharmaceutica Central Americas Ltd., a Delaware
corporation and an affiliate of C.U.R.E. ("C.U.R.E. C/A Ltd."). C.U.R.E. C/A
Ltd. was required to purchase a minimum of 20,000 milliliters of Reticulose
during the first year following approval and such approval had to be obtained
within one year of entering into this agreement. C.U.R.E. was unable to obtain
such approval and AVR terminated C.U.R.E.'s exclusive distribution rights,
effective May 30, 1995, following acknowledgment by C.U.R.E. and C.U.R.E. C/A
Ltd. that neither had obtained approvals.

                                       36

         Agreements with AVIX and Unistone.

         As the result of the termination of agreements with C.U.R.E. and
C.U.R.E. C/A Ltd., AVR entered into an agreement, dated as of June 2, 1995, with
AVIX, pursuant to which AVIX has been granted the exclusive import and
distribution rights during a period of five years from the date that AVIX
obtains Approval for any of the countries formerly within the C.U.R.E. Territory
(the "AVIX Far East Agreement"), and a separate Exclusive Distribution Agreement
with AVIX with respect to Mexico, which rights previously belonged to C.U.R.E.
C/A Ltd. AVIX has informed AVR that it received initial authorization for
testing Reticulose in Mexico in July 1998, and that it has commenced
negotiations with parties in China for initial authorization for testing
Reticulose, following which Approval for those countries shall be sought. AVR
has been informed by AVIX that certain of the principals of AVIX (including
Leonard Cohen who is an officer and shareholder thereof) were formerly
principals of C.U.R.E. The terms of the agreement with AVIX are substantially
similar to the agreements with C.U.R.E. and C.U.R.E. C/A Ltd. except that the
territory in the AVIX Agreement does not include Thailand, Malaysia and
Singapore but does include Macao. The Approval has not been obtained to date.

         On December 28, 1995, AVR entered into a separate agreement with AVIX
and Beijing Unistone Pharmaceutical Co., Ltd. ("Unistone"), a company organized
under the laws of the People's Republic of China, with headquarters in Beijing,
China (the "Unistone-AVIX Agreement"). In connection with the Unistone-AVIX
Agreement, AVR and AVIX agreed to utilize the services of Unistone for the
purposes of securing approval to test Reticulose in China, with the intent of
gaining Approval for China. Under the Unistone-AVIX Agreement, during a period
of three years commencing on the date of Approval for China, Unistone shall be
the exclusive distributor and have a limited trademark license for Reticulose in
China. Unistone is obligated to purchase not more than 100,000 doses of 0.5 ml
each in bulk form or 20,000 ampules of 0.5 ml doses for purposes of seeking
Approval for China, at least 1,000,000 doses by the first anniversary of
Approval for China, at least 3,000,000 doses during the next 12-month period,
and at least 10,000,000 doses during each subsequent 12-month period, all at a
purchase price of U.S. $1.00 per 0.5 ml dose shipped in bulk, or U.S. $1.26 per
dose if ordered in prepackaged, four-dose 2 ml ampules. This purchase price is
to be reduced by an aggregate of $100,000 on account of a fee to Unistone for
trials and testing of Reticulose for Approval for China. If these annual minimum
purchase requirements are satisfied, the period of the agreement is
automatically extended through the eighth anniversary of the date of Approval.
There are no minimum purchase requirements to be met by AVIX under the
AVIX-Unistone Agreement. In addition, AVIX is obligated to pay Unistone $50,000
for its services in seeking Approval for China. As of December 31, 1997, AVR had
given Unistone, for testing purposes, 1,600 ampules of Reticulose without
charge. Unistone has not fulfilled its obligation under the agreement to obtain
Approval before April 1996. AVR has not terminated the AVIX-Unistone Agreement
because AVR has not identified another source it believes will be more
successful in obtaining Approval.

         Under a separate agreement between AVR and AVIX, AVIX shall receive a
royalty equal to 12.5% of the total sales of Reticulose in China, Japan, Taiwan,
Hong Kong and Macao so long as AVR owns any right to Reticulose. AVIX also is
entitled to certain payments by AVR in the event that AVR sells manufacturing
rights for Reticulose.

                                       37
<PAGE>

         In July, 1996, the AVIX Far East Agreement was amended to grant AVIX
the additional country of Macao and reflect AVIX's waiver of its rights with
respect to the countries of Singapore, Thailand and Malaysia, as well as AVIX's
penalty rights under the AVIX Far East Agreement that would have vested in the
event that AVR could not produce sufficient quantities of Reticulose within
certain periods of time. The penalty rights were waived, in part, because AVIX
has not yet generated a sufficient demand for Reticulose within its distribution
territory.

         The period of time during which AVIX must obtain Approval for any of
the countries in its territory under the AVIX Far East Agreement was extended to
June 1, 1997, subject to AVIX continuing to pay $8,000 per month to AVR. AVR has
not received the $8,000 monthly payment since November, 1996; AVR has received a
total of $40,000 in payments from AVIX. Pursuant to recent discussions with AVIX
regarding the AVIX Far East Agreement, AVR and AVIX have agreed that, in lieu of
the $8,000 monthly payment discussed above, AVIX will fund studies assessing the
efficacy of Reticulose that may be performed in Mexico. If AVIX is complying
with the AVIX Far East Agreement, including certain annual minimum purchase
requirements after Approval is obtained (see below) of which there can be no
assurance, the term is automatically extended for five additional five year
terms. The agreements with AVIX further provide that the results of all studies,
research data, documentation and research publications regarding Reticulose in
which AVIX has an interest are owned by AVR.

         The separate agreement for Mexico requires Approval within one year and
has minimum annual purchase requirement commencing at 20,000 milliliters. AVR
extended the period for AVIX to secure Approval from Mexico because management
of AVR believes that AVIX is diligently seeking such Approval from the Ministry
of Health of Mexico. In July 1998, the Ministry of Health of Mexico granted
authorization for testing and analysis of Reticulose on human subjects with HIV
and AIDS, and AVR is currently exploring candidates to perform such tests.
Through March 1999, no studies have commenced in Mexico and no amounts for such
testing have been advanced by AVIX.

         AVIX shall be required, pursuant to the AVIX Far East Agreement, to
purchase Reticulose for $500,000 upon obtaining Approval and after one year
after Approval for China, AVIX is required to purchase Reticulose for an
additional $500,000 at $12 per 2 ml ampule.

         Agreement with Commonwealth.

         Under an Exclusive Distribution Agreement, dated October 24, 1994, as
supplemented on November 2, 1995 (collectively, the "Commonwealth Agreement")
with Commonwealth, AVR has granted to Commonwealth, subject to certain
conditions precedent, the exclusive right to market and sell AVR's
pharmaceutical drug Reticulose within the territories of the Channel Islands,
The Isle of Man, the British West Indies, Jamaica, Haiti, Bermuda and Belize
(collectively, the "Commonwealth Territories"), and the right (not exclusive) to
import, warehouse, market, sell and distribute Reticulose within the territory
of Saudi Arabia. The term of the Commonwealth Agreement as to the Commonwealth
Territories is for successive three year periods (each extension period being
with the prior mutual consent of the parties) from the date Commonwealth obtains
Approval for any one of the Commonwealth Territories. The Approval has not been
obtained to date.

                                       38
<PAGE>

         Pursuant to the Commonwealth Agreement, Commonwealth purchased from AVR
1,500 ampules of Reticulose at a purchase price of $12.00 per ampule (2
milliliters per ampules) and delivered to AVR $5,000 as a signing payment (for a
total payment of $23,000). Commonwealth has advised AVR that to date it has sold
approximately $1,200 worth of Reticulose in the Commonwealth Territories.
Further, pursuant to the Commonwealth Agreement, in the event Approval for any
of the Commonwealth Territories is obtained, Commonwealth is obligated to
purchase from AVR $225,000 worth of Reticulose within one year from the date of
Approval for any of the Commonwealth Territories; $642,000 worth of Reticulose
during the second year from the date of Approval for any of the Commonwealth
Territories; and $1,026,000 worth of Reticulose during the third year from the
date of Approval for any of the Commonwealth Territories. Commonwealth also is
obligated to purchase from AVR $225,000 worth, $822,000 worth and $1,914,000
worth of Reticulose, respectively, during the first three years from the date of
Approval. In addition, pursuant to the Commonwealth Agreement, AVR has granted
to Commonwealth the right to acquire 3,000,000 shares of the common stock at a
purchase price of $0.25 per share at any time and from time to time for a period
of one year from the date that certain tests are conducted and a paper is
published with respect to such test of Reticulose. AVR has been informed by
Commonwealth that certain of the affiliates of Commonwealth were formally
affiliated with Plata.

         Agreement with Dormer Laboratories Inc.

         On November 9, 1993, AVR entered into an agreement by which it granted
to Dormer Laboratories Inc., a Canadian corporation ("Dormer"), the exclusive
rights to import, warehouse, market, sell and distribute Reticulose within
Canada for a period of five years from the grant of import approval for Canada,
provided that Dormer meets certain Reticulose purchase minimums. Because
Approval for Canada was not obtained by November 9, 1995, AVR had the right to
terminate this agreement on 90 days prior written notice to Dormer. Upon notice
by AVR, the agreement was terminated in August 1998.

         Pursuant to an Amended and Restated Employment Agreement dated as of

Agreement"), AVR employs Dr. Hirschman, on a full business time basis as its
President, Chief Executive Officer, Chief Scientific Officer and Chairman of its
Scientific Advisory Board, with duties including supervising day-to-day
operations of AVR, including management of scientific, medical, financial,
regulatory and corporate matters, establishing appropriate laboratory, executive

Employment Agreement includes an agreement by AVR that Dr. Hirschman will be
nominated as a Director of AVR for the duration of Dr. Hirschman's employment by
AVR under the Employment Agreement, and voting agreements regarding the election

         Pursuant to the Employment Agreement, the term of Dr. Hirschman's
employment continues until December 31, 2000 and will continue for one year
periods thereafter unless either AVR or Dr. Hirschman gives the other notice at
least two years in advance that such one year automatic extension shall be

(as defined therein), all unvested stock options, benefits under stock bonus

other leave as AVR provides to all of its employees. The Employment Agreement
also provides for the payment of $100,000 to Dr. Hirschman on the date an IND

otherwise) of all or substantially all of AVR's assets.

         Dr. Hirschman has agreed that he will assign to AVR all patents he
develops which result from his knowledge acquired while performing his duties
under the Employment Agreement, and that, if his employment under the Employment
Agreement is terminated by AVR "for cause" or by Dr. Hirschman otherwise than

(1)  The persons named in this table have sole voting power with respect to all
     shares shown as beneficially owned by them, except as indicated in other
     footnotes to this table. In computing the number of shares beneficially
     owned by a person and the percentage ownership of that person, shares of
     common stock subject to options or warrants held by that person that are
     currently exercisable or exercisable within 60 days after April 24, 1999,
     are deemed outstanding. According to American Stock Transfer & Trust
     Company, the transfer agent for the common stock, 301,340,183 shares of the
     common stock were outstanding as of the close of business on April 24,
     1999.

     during the term of Dr. Hirschman's employment under that agreement, shall
     vote all shares of the common stock owned or voted by them in favor of Dr.
     Hirschman as a director of AVR. That agreement, however, does not restrict
     or otherwise limit their right to sell their shares to third parties
     without restriction. The Employment Agreement also provides that Dr.
     Hirschman, during that term, shall take no action which shall preclude
     Messrs. Friedland and Bregman from being nominees as directors of AVR and
     that Dr. Hirschman shall vote all shares of the common stock owned or voted
     by him in favor of Messrs. Friedland and Bregman as directors of AVR. See
     "- Employment Contracts, Termination of Employment and Change-in-Control
     Arrangements."

                              SELLING SHAREHOLDERS

         The following table sets forth certain information regarding the
beneficial ownership of the common stock as of the date of this prospectus by
each of the selling shareholders assuming the full conversion of the 1998
Debenture (based on application of the formula for computing the applicable
conversion price as provided in the 1998 Debenture), the Warrants and the
Options. Unless otherwise indicated below, to the knowledge of AVR, all persons
listed below have sole voting and investment power with respect to the shares of
common stock, except to the extent authority is shared by spouses under
applicable law. Based on the average of the closing bid and ask prices of the
common stock on April 26, 1999, as reported on the OTC Electronic Bulletin Board
($0.23), and an applicable conversion price of $0.1656, full conversion of the
1998 Debenture would yield 9,057,971 shares of common stock.

         The information included below is based upon information provided by
the selling shareholders. Because the selling shareholders may offer all, some
or none of their shares, no definitive estimate as to the number of shares that
will be held by the selling shareholders after such offering can be provided and
the following table has been prepared on the assumption that all shares offered
under this prospectus will be sold.

1.   As required by regulations of the Commission, the number of shares shown as
     beneficially owned include shares which can be purchased within 60 days
     after April 26, 1999. The actual number of shares of common stock
     beneficially owned is subject to adjustment and could be materially more or

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

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


                            DESCRIPTION OF SECURITIES

Common Stock

         The authorized capital stock of AVR consists of 1,000,000,000 shares of
common stock, par value $0.00001 per share. All shares of common stock now
outstanding are fully paid for and non-assessable. The holders of common stock:

         o        have equal ratable rights to dividends from funds legally
                  available therefore, when, as and if declared by the Board of
                  Directors of AVR;

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

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

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

<PAGE>

                                 USE OF PROCEEDS

         AVR will not receive any of the proceeds from the sale of the shares
offered hereunder by the selling shareholders.


                              PLAN OF DISTRIBUTION

         Sales of the shares may be made from time to time by the selling
shareholders, or, subject to applicable law, by pledgees, donees, distributees,
transferees or other successors in interest. Such sales may be made on the OTC
Bulletin Board, in another over-the-counter market, on a national securities
exchange (any of which may involve crosses and block transactions), in privately
negotiated transactions or otherwise or in a combination of such transactions at
prices and at terms then prevailing or at prices related to the then current
market price, or at privately negotiated prices. In addition, any shares covered
by this prospectus which qualify for sale pursuant to Section 4(l) of the
Securities Act or Rule 144 promulgated thereunder may be sold under such
provisions rather than pursuant to this prospectus. Without limiting the
generality of the foregoing, the shares may be sold in one or more of the
following types of transactions: (a) a block grade in which the broker-dealer so
engaged will attempt to sell the shares as agent but may position and resell a
portion of the block as principal to facilitate the transaction; (b) purchases
by a broker or dealer as principal and resale by such broker or dealer for its
account pursuant to this prospectus; (c) an exchange distribution in accordance
with the rules of such exchange; (d) ordinary brokerage transactions and
transactions in which the broker solicits purchasers, and (e) face-to-face
transactions between sellers and purchasers without a broker-dealer. In
effecting sales, brokers or dealers engaged by the selling shareholders may
arrange for other brokers or dealers to participate in the resales.

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

         Brokers, dealers or agents may receive compensation in the form of
commissions, discounts or concessions from selling shareholders in amounts to be
negotiated in connection with the sale. Such brokers or dealers and any other
participating brokers or dealers may be deemed to be 'underwriters' within the
meaning of the Securities Act in connection with such sales and any such
commission, discount or concession may be deemed to be underwriting discounts or
commissions under the Securities Act.

         Information as to whether underwriters who may be selected by the
selling shareholders, or any other broker-dealer, is acting as principal or
agent for the selling shareholders, the compensation

                                       50
<PAGE>

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

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

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

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

To the Stockholders and Directors
Advanced Viral Research Corp.
  (A Development Stage Company)
Hallandale, Florida

We have audited the accompanying consolidated balance sheets of Advanced Viral
Research Corp. (A Development Stage Company) as of December 31, 1998 and 1997,
and the related consolidated statements of operations, stockholders' equity and
cash flows for each of the years in the three year period ended December 31,
1998 and for the period from inception (February 20, 1984) to December 31, 1998.
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, 1998 and 1997
and the results of their operations and their cash flows for each of the years
in the three year period ended December 31, 1998 and for the period from
inception (February 20, 1984) to December 31, 1998 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 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, 1998 AND 1997



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. 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, RETICULOSE, to commence
             commercial operations. The Company was in the development stage at
             December 31, 1998.

         Principles of Consolidation

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

         Cash and Cash Equivalents

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

         Investments

             Investments consist of certificates of deposit with maturities
             greater than three months, carried at cost which is market value,
             U.S. Government securities and discount notes and U.S. Treasury
             Bills. The U.S. Government securities, notes and treasury bills are
             classified as "held to maturity" and are carried at amortized cost
             which approximates market value.

         Property and Equipment

             Property and equipment are recorded at cost and depreciated 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.

         Deferred Compensation Cost

             Deferred compensation costs are recognized based on the fair value
             for non-employee stock options. Compensation cost is amortized over
             the life of the option period which is either shorter than or
             essentially equivalent to the period for which the services are to
             be provided. Compensation expense is classified as general and
             administrative.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Continued)



NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

         Revenue Recognition

             The limited sales generated by the Company have consisted of sales
             of RETICULOSE for testing and other purposes. Sales are recorded by
             the Company when the product is shipped to customers.

         Reclassifications

             Certain amounts in the 1997 and 1996 financial statements have been
             reclassified to conform to 1998 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.


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 RETICULOSE 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. Management does not
         anticipate registration or other approval of RETICULOSE in the near
         future in the United States. Unless and until RETICULOSE 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 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 such equity financing, if and when required, will be available. In
         the event that such equity financing is not available, in order to
         continue operations, management anticipates that they will have to
         defer their salaries. During 1998 and 1997, the Company obtained debt
         financing and may seek additional debt financing if the need arises. No
         assurance can be given that the Company will be able to sustain its
         operations until FDA approval is granted or that any approval will ever
         be granted. The Company expects to apply for approval with the FDA by
         May 15, 1999. These factors raise substantial doubt about the Company's
         ability to continue as a going concern. 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
         worldwide, except within the Bahamas, for $50,000. The Company also
         purchased inventory of RETICULOSE from LTD for $45,000 and was
         obligated to pay $3 per ampule of RETICULOSE 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.

NOTE 7.  SECURITIES PURCHASE AGREEMENT

         On December 22, 1998, the Company entered into a Securities Purchase

         4,917,276 shares of common stock for an aggregate purchase price of
         $802,500. The agreement also provides 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.

         As of December 31, 1998, the Company received $600,000 towards the
         total purchase price.

         As of January 7, 1999, the remaining $202,500 was received and the
         appropriate shares were issued to the purchasers.

NOTE 8.  CONVERTIBLE DEBENTURES

         On February 21, 1997, in order to finance research and development, the
         Company sold $1,000,000 principal amount of its ten-year 7% Convertible
         Debenture (the "February Debenture") due February 28, 2007, to RBB Bank
         Aktiengesellschaft ("RBB"). Accrued interest under the February
         Debenture is payable semi-annually, computed at the rate of 7% per
         annum on the unpaid principal balance from February 21, 1997 until the
         date of interest payment. The February 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 February Debenture is convertible, at the option of the holder,
         into shares of common stock.

NOTE 8.  CONVERTIBLE DEBENTURES (Continued)

         The assured incremental yield on the February Debenture was measured
         based on the date of issuance of the security and amortized to interest
         expense over the conversion period which ended on May 29, 1997 which
         was the first date full conversion could occur. The interest expense
         relating to this measurement was $4,768.

         During 1997, RBB exercised its right to convert the principal amount of
         the February Debenture into 6,675,982 shares of the Company's common
         stock at conversion prices ranging from $.1162 to $.2002 per share.

         In connection with the issuance of the February Debenture, the Company
         issued to RBB three warrants (the "February warrants") to purchase
         common stock, each such February warrant entitling the holder to
         purchase, from February 21, 1997 through February 28, 2007, 178,378
         shares of common stock. The exercise price of the three February
         warrants are $0.288, $0.576 and $0.864 per warrant share, respectively.
         The fair value of the February warrants was estimated to be $37,000
         ($.021 per warrant) based upon a financial analysis of the terms of the
         warrants using the Black-Sholes Pricing Model with the following
         assumptions: expected volatility of 20%; a risk free interest rate of
         6% and an expected holding period of ten years (RBB exercised its right
         to convert within one year). This amount has been reflected in the
         accompanying consolidated financial statements as interest expense
         related to the convertible debenture.

         Based on the terms for conversion associated with the February
         Debenture, there is an intrinsic value associated with the beneficial
         conversion feature of $413,793. This amount was fully amortized to
         interest expense in 1997 with a corresponding credit to additional
         paid-in capital.

         In October 1997, in order to finance further research and development,
         the Company sold $3,000,000 principal amount of its ten-year 7%
         Convertible Debenture (the "October Debenture") due August 30, 2007, to
         RBB. Accrued interest under the October 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 October
         Debenture until the date of interest payment. The October 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 October Debenture is convertible, at the option of
         the holder, into shares of common stock.

         During 1997, RBB exercised its right to convert $120,000 of the
         principal amount of the October Debenture into 772,201 shares of the
         Company's common stock at a conversion price of $.1554 per share.

         During 1998, RBB exercised its right to convert the remaining
         $2,880,000 of the principal amount of the October Debenture into
         16,805,333 shares of the Company's common stock at conversion prices
         ranging from $.13 to $.23 per share.

NOTE 8.  CONVERTIBLE DEBENTURES (Continued)

         In connection with the issuance of the October Debenture, the Company
         issued to RBB three warrants (the "October warrants") to purchase
         Common Stock, each such October warrant entitling the holder to
         purchase, from the date of grant through August 30, 2007, 600,000
         shares of the Common Stock. The exercise price of the three October
         warrants are $0.20 , $0.23 and $0.27 per warrant share, respectively.
         The fair value of the three October warrants was established to be
         $106,571 ($.178 per warrant), $97,912 ($.163 per warrant) and $87,472
         ($.146 per warrant), respectively, based upon a financial analysis of
         the terms of the warrants using the Black-Sholes Pricing Model with the
         following assumptions: expected volatility of 20%; a risk free interest
         rate of 6% and an expected holding period of ten years (RBB exercised
         its right to convert within one year). This amount has been reflected
         in the accompanying consolidated financial statements as a discount on
         the convertible debenture, with a corresponding credit to additional
         paid-in capital, and was fully amortized to interest expense over the
         actual conversion period.

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

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

         In connection with the issuance of the November Debenture, the Company
         issued to RBB two warrants (the "November Warrants") to purchase Common
         Stock, each such November Warrant entitling the holder to purchase
         375,000 shares of the Common Stock at any time and from time to time
         through October 31, 2008. The exercise price of the two November
         Warrants are $.20 and $.24 per warrant share, respectively. The fair
         value of the November warrants was estimated to be $48,000 ($.064 per
         warrant) based upon a financial analysis of the terms of the warrants
         using the Black-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 has been reflected in
         the accompanying consolidated financial statements as interest expense
         related to the convertible debenture.

         Based on the terms for conversion associated with the November
         Debenture, there is an intrinsic value associated with the beneficial

         deferred interest expense and recorded as a reduction of the
         convertible debenture with a corresponding credit to additional paid-in
         capital and is being amortized to interest expense over a one year
         period beginning November 16, 1998 (date of debenture), based on
         management's expectation of when complete conversion will occur. The
         interest expense relative to this item is $52,083 for 1998.

NOTE 9.  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 RETICULOSE in an amount equal to 5% of net
             sales in the United States and 4% of net sales in foreign
             countries. 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 RETICULOSE. Although the Company is
             unaware of any such claims or threatened claims since RETICULOSE
             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 RETICULOSE. As of the date
             hereof, the Company does not have product liability insurance for
             RETICULOSE. 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
             materially adversely affect the Company.

         Lack of Patent Protection

             The Company does not presently have a patent for RETICULOSE but the
             Company has two patents for the use of RETICULOSE as a treatment.
             The Company currently has 32 patent applications pending with the
             U.S. Patent Office. 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.

         Capital Lease

             During 1998 the Company entered into a purchase lease agreement for
             equipment totaling $222,318. The lease calls for monthly payments
             of $4,529 for 60 months commencing on September 1998 and expiring
             on July 2003. Future minimum capital lease payments and the net

         TESTING AGREEMENTS

         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 RETICULOSE 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. The Clinical
             Trials did not include a placebo control group or references to any
             other antiviral drug.

             Pursuant to the Argentine Agreement, the Company delivered $34,000
             to DCT to cover out-of-pocket expenses associated with the Clinical
             Trials. The Argentine Agreement further provides that at the
             conclusion of the Clinical Trials, DCT shall cause Dr. Flichman to
             prepare and deliver a written report to the Company regarding the
             methodology and results of the Clinical Trials (the "Written
             Report"). In September 1996, the Written Report was delivered by
             Dr. Flichman to the Company. Upon delivery of the Written Report to
             the Company, the Company delivered to the principals of DCT options
             to acquire 2,000,000 shares of the Company's common stock for a
             period of one year from the date of the delivery of the Written
             Report, at a purchase price of $.20 per share. Pursuant to several
             amendments, the DCT options are exercisable through April 30, 1999
             at an exercise price of $.21 per share. As of December 31, 1998,
             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
             RETICULOSE 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 RETICULOSE 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 has advanced
             approximately $665,000 which is accounted for as a research and
             development expense. The amounts have been used to cover expenses
             associated with clinical activities of the HIV-HPV Study.

         TESTING AGREEMENTS (Continued)

         Argentine Agreement (Continued)

             The HIV-HPV Agreement provides that (i) in the event the date from
             the HIV-HPV Study is used in connection with RETICULOSE 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
             RETICULOSE for the treatment of persons diagnosed with Herpes
             Labialis/Genital Infections (the "Herpes Study") and HPV (the "HPV
             Topical Study").

             In connection with the Herpes Study and the HPV Topical Study
             (collectively, the "Studies"), the Company has advanced
             approximately $58,000 and $132,800, respectively. Such expenses are
             accounted for as research and development expenses. 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 RETICULOSE 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 respectively
             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 RETICULOSE with those taking
             a three drug cocktail and a placebo. As of December 31, 1998, 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
             RETICULOSE for the treatment of rheumatoid arthritis in humans. In
             connection with this study, the Company has advanced approximately
             $75,000 which has been accounted for as research and development
             expenses.

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

         Barbados Study

             A double blind study assessing the efficacy of the Company's drug
             RETICULOSE in 43 human patients diagnosed with HIV (AIDS) is being
             conducted at the Queen Elizabeth Hospital, Bridgetown, Barbados
             (the "Barbados Study"). As of December 31, 1998, the Company has
             expended approximately $385,000 to cover the costs of the Barbados
             Study. In December 1996, the Company received from the coordinators
             of the Barbados Study, a written summary of results of the Barbados
             Study (the "Written Summary").

             In July 1998, the Company authorized expenditures of up to $45,000
             to study the effects of RETICULOSE in inhibiting the mutation of
             the AIDS virus. As of December 31, 1998, the Company has advanced
             approximately $5,000 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 RETICULOSE 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
             RETICULOSE using kidney tumor model systems. In addition, NCI will
             study the effects of RETICULOSE 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
             RETICULOSE.

         CONSULTING AGREEMENTS

         Hirschman Agreement

             In May 1995, the Company entered into a consulting agreement with
             Shalom Hirschman, M.D., Professor of Medicine of Mt. Sinai School
             of Medicine, New York, New York and Director of Mt. Sinai's
             Division of Infectious Diseases and now president of AVRC, whereby
             Dr. Hirschman was to provide consulting services to the Company
             through May 1997. The consulting services included the development
             and location of pharmacological and biotechnology companies and
             assisting the Company in seeking joint ventures with and financing
             of companies in such industries.

             In connection with the consulting agreement, the Company issued to

             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. In addition and in connection with entering into the
             consulting agreement with Dr. Hirschman, the Company issued to a
             person unaffiliated with the Company, 100,000 shares of the
             Company's common stock, and an option to acquire for a period of
             one year, from June 1, 1995, an additional 500,000 shares at a
             purchase price of $.18 per share. As of December 31, 1998, 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, 1999 at an
             exercise price of $.19 per share, of which options to acquire
             500,000 shares were assigned by Dr. Hirschman to Richard Rubin,
             consultant to Dr. Hirschman; (ii) options to purchase 5,000,000

             March 24, 1997 and ending March 23, 1999 at an exercise price of
             $.27 per share, of which options to acquire 500,000 shares were
             assigned by Dr. Hirschman to Richard Rubin, consultant to Dr.
             Hirschman; and (iii) options to purchase 5,000,000 shares
             exercisable at any time and from time to time commencing March 24,
             1998 and ending March 23, 1999 at an exercise price of $.36 per
             share, of which options to acquire 500,000 shares were assigned by
             Dr. Hirschman to Richard Rubin, consultant to Dr. Hirschman. In
             addition, the Company has agreed to cause the shares underlying
             these options to be registered so long as there is no cost to the
             Company. As of December 31, 1998, 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.

             Bernard Friedland and William Bregman will vote in favor of Dr.
             Hirschman as a director of the Company, for the duration of Dr.
             Hirschman's employment, and since October 1996, Dr. Hirschman has
             served as a member of the Company's Board of Directors.

             On February 18, 1998, the Board of Directors authorized a $100,000
             bonus to Dr. Hirschman and granted options to acquire 23,000,000
             shares of stock at $0.27 per option share provided that the Company
             is granted FDA approval for testing in the United States.

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

NOTE 9.  COMMITMENTS AND CONTINGENCIES (Continued)

         CONSULTING AGREEMENTS (Continued)

         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 April 30, 1999), the option to acquire 3,000,000
             shares of common stock of the Company at an exercise price of $.09
             per share (which exercise price has been increased to $.15 per
             share) (the "September 1992 Cohen Options"). As of December 31,
             1998, 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.

             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"). The Company has been informed that
             Messrs. Cohen, Bauer and Rizzuto are principals of a firm which has
             been granted certain distribution rights, which were terminated on
             May 31, 1995. Through December 31, 1997, 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 April 30, 1999 at an option price of $.13. The Company
             agreed to issue to Cohen an additional 300,000 shares in 1995 at a
             time when the shares were valued at $.14 per share, in
             consideration for expenditures incurred by Mr. Cohen in connection
             with securing for the benefit of the Company and the affiliated
             distributor, the continued services of a doctor.

         Cohen Agreements (Continued)

             The issuance of the September 1992 Cohen Shares, the February 1993
             Cohen Shares, the April 1994 Cohen Shares and the Bauer and Rizzuto
             Shares have been accounted for as an administrative expense in the
             amount of the Company's valuation of such shares as of the issuance
             date. During the year ended December 31, 1996, Mr. Cohen was issued
             300,000 shares for services rendered. These shares were accounted
             for as an administrative expense in the amount of the Company's
             valuation of such shares as of the issuance date.

         Chinnici Agreement

             In July 1998, the Company entered into a consulting agreement with
             Dr. Angelo A. Chinnici for a term extending to December 31, 2000.
             Such agreement calls for Dr. Chinnici to provide assistance in
             connection with research, development, production, marketing and
             sale of RETICULOSE. Additionally, Dr. Chinnici will testify before
             the FDA in connection with an application for approval of
             RETICULOSE and will provide detailed clinical reports regarding
             patients observed by him. Dr. Chinnici will receive options to
             purchase 300,000 shares at an exercise price of $.30 per share. The
             options will be exercisable in equal installments on January 1,
             1999 and 2000 and December 15, 2000.

         DISTRIBUTION AGREEMENTS

         The Company currently is a party to separate agreements with four
         different entities (the "Entities"), whereby the Company has granted
         exclusive rights to distribute RETICULOSE in the countries of China,
         Japan, Macao, Hong Kong, Taiwan, Mexico, Argentina, Bolivia, Paraguay,
         Uruguay, Brazil, Chile, Channel Islands, The Isle of Man, British West
         Indies, Jamaica, Haiti, Bermuda, Belize and Saudi Arabia. Pursuant to
         these agreements, distributors are obligated to cause RETICULOSE to be
         approved for commercial sale in such countries and upon such approval,
         to purchase from the Company certain minimum quantities of RETICULOSE
         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. No sales have been made by the
         Company under the distribution agreements other than for testing
         purposes.

         Additionally, pursuant to one of the distributions agreements, the
         Company granted the distributor the right to acquire 3,000,000 shares
         of the Company's common stock at a purchase price of $.25 (which has
         been increased to $.26) upon the completion of certain tests and the
         publication of a paper with respect to such tests. During May 1998,
         300,000 shares of common stock were issued pursuant to exercise of
         these options for an aggregate exercise price of $78,000.

NOTE 10. STOCKHOLDERS' EQUITY

         During 1997, the Company issued 10,931,516 shares of common stock for
         an aggregate consideration of $1,412,166. These amounts were comprised
         of the issuance of common stock pursuant to the exercise of stock
         options of 3,333,333 shares for $247,666 and the issuance of common
         stock in exchange for consulting services of 150,000 shares for
         consideration of $44,500 and the issuance of common stock upon
         conversion of debt of 7,448,183 shares for $1,120,000.

         During 1998, the Company issued 18,460,333 shares of common stock for
         an aggregate consideration of $3,158,400. The amounts were comprised of
         the issuance of common stock pursuant to the exercise of stock options
         of 1,555,000 shares for $257,400 and the issuance of common stock in
         exchange for consulting services of 100,000 shares for consideration of
         $21,000 and the issuance of common stock upon commission of debt of
         16,805,333 shares for $2,880,000.


NOTE 11. INCOME TAXES

         The Company accounts for income taxes under the provisions of Statement
         of Financial Accounting Standards (SFAS) No. 109, Accounting for Income
         Taxes. SFAS No. 109 is an asset and liability approach for computing
         deferred income taxes.

         As of December 31, 1998 and 1997, the Company had a net operating loss
         carryforward for Federal income tax reporting purposes amounting to
         approximately $9,700,000 and $6,300,000, which expire in varying
         amounts to 2018.

         The Company presently has one significant temporary difference between
         financial reporting and income tax reporting relating to interest
         expense on the beneficial conversion feature of the convertible debt.
         The components of the deferred tax asset as of December 31, 1998 and
         1997 were as follows:

         As of December 31, 1998, sufficient uncertainty exists regarding the

NOTE 12. 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, 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 December 31, 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, 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.

         The fair value of non-current investments, primarily U.S. government
         obligations, have been estimated using quoted market prices. At
         December 31, 1998, 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.


NOTE 13. DEFERRED COMPENSATION COST

         As more fully described in Note 9 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
         life of the option period. The fair value of the stock options used to
         compute deferred compensation cost is the estimated present value at
         grant date using the Black-Sholes option pricing model with the
         following assumptions: Expected volatility of 20%; a risk-free interest
         rate of 6% and an expected holding period ranging from 1-3 years. The
         deferred compensation cost is reported as a component of stockholders'
         equity. At December 31, 1998 and 1997, there were approximately
         5,500,000 and 7,000,000 option shares outstanding with a weighted
         average exercise price of $0.195 per share.

Item 14.  Indemnification of Directors and Officers

         Article Ninth of AVR's Certificate of Incorporation contains the
following provision with respect to indemnification of Directors and Officers:

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

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

                  (a) A corporation shall have power to indemnify any person who
         was or is a party or is threatened to be made a party to any
         threatened, pending or completed action, suit or proceeding, whether
         civil, criminal, administrative or investigative (other than an action
         by or in the right of the corporation) by reason of the fact that the
         person is or was a director, officer, employee or agent of the
         corporation, or is or was serving at the request of the corporation as
         a director, officer, employee or agent of another corporation,
         partnership, joint venture, trust or other enterprise, against


                                      II-1

<PAGE>


         expenses (including attorneys' fees), judgments, fines and amounts paid
         in settlement actually and reasonably incurred by the person in
         connection with such action, suit or proceeding if the person acted in
         good faith and in a manner the person reasonably believed to be in or
         not opposed to the best interests of the corporation, and, with respect
         to any criminal action or proceeding, had no reasonable cause to
         believe the person's conduct was unlawful. The termination of any
         action, suit or proceeding by judgment, order, settlement, conviction,
         or upon a plea of nolo contendere or its equivalent, shall not, of
         itself, create a presumption that the person did not act in good faith
         and in a manner which the person reasonably believed to be in or not
         opposed to the best interests of the corporation, and, with respect to
         any criminal action or proceeding, had reasonable cause to believe that
         the person's conduct was unlawful.

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

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

                  (d) Any indemnification under subsections (a) and (b) of this
         section (unless ordered by a court) shall be made by the corporation
         only as authorized in the specific case upon a determination that
         indemnification of the present or former director, officer, employee or
         agent is proper in the circumstances because the person has met the
         applicable standard of conduct set forth in subsections (a) and (b) of
         this section. Such determination shall be made, with respect to a
         person who is a director or officer at the time of such determination,
         (1) by a majority vote of the directors


                                      II-2

<PAGE>



         who are not parties to such action, suit or proceeding, even though
         less than a quorum, or (2) by a committee of such directors designated
         by majority vote of such directors, even though less than a quorum, or
         (3) if there are no such directors, or if such directors so direct, by
         independent legal counsel in a written opinion, or (4) by the
         stockholders.

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

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

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

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

Item 17.  Undertakings

       The undersigned registrant hereby undertakes:

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

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

                  (ii) To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20 percent change in the
maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement.

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

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

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

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

"Registration Statement"), filed by the Company with the U.S. Securities and
Exchange Commission (the "Commission").

         The Registration Statement relates to an offering of up to 47,192,584

         (ii)     9,057,971 shares of the Company's common stock issuable upon
                  the conversion of a convertible debenture issued in November

                  adjustment and could be materially less or more, depending
                  upon factors that cannot be predicted at this time, including,
                  among others, the future market price of the Company's common
                  stock;

         (iii)    5,451,922 shares of the Company's common stock issuable upon

submitted to us and the truth and correctness of any representations and
warranties contained therein.

         We have also consulted with officers and directors of the Company and
have obtained such representations with respect to the matters of fact as we
have deemed necessary or advisable for purposes of rendering the opinion
hereinafter expressed. We have not independently verified the factual statements
made to us in connection therewith, nor the veracity of such representations.

         Based upon and subject to the foregoing, we are of the opinion that,
after the Commission has declared the Registration Statement to be effective
(such Registration Statement as is finally declared effective and the form of
Prospectus contained therein being hereinafter referred to as the "Registration
Statement" and the "Prospectus," respectively) and when the applicable
provisions of the "Blue Sky" or other state securities laws shall have been
complied with, the Shares covered by the Registration Statement, upon receipt of
payment therefor and the satisfaction of all other conditions as referenced in
the Debenture, the Warrants, the Options and all agreements relating thereto,
will constitute legally issued securities of the Company, fully paid and
non-assessable.

         We hereby consent to the use of this opinion as an exhibit to the
Registration Statement and to the reference of this law firm in the Prospectus
under the heading "LEGAL MATTERS." In giving this consent, we do not hereby
admit that we are in the category of persons whose consent is required under
Section 7 of the Act or the rules and regulations of the Commission promulgated
thereunder.

                                            Respectfully submitted,


                                            /s/ BERMAN WOLFE & RENNERT, P.A.
