                               PROSPECTUS SUMMARY

         This summary highlights information contained elsewhere in our
prospectus. This summary does not contain all of the information that you should
consider before investing in our common stock. You should read the entire
prospectus carefully, especially the risks of investing in our common stock
discussed under "High Risk Factors."

OUR COMPANY

         Viragen, Inc. was organized in 1980 and is in the business of
researching and developing products which help the human immune system resist
viral infections. Our primary product is a natural interferon product named
Omniferon(TM) which is produced from human white blood cells. Natural interferon
stimulates and controls the human immune system. In addition, interferon may
stem the growth of various viruses including those involved with diseases such
as hepatitis, multiple sclerosis, cancer and HIV/AIDS.

         Our product has not been approved by the United States Food and Drug
Administration or the European Union regulatory authorities. Viragen intends to
seek Food and Drug Administration and European Union regulatory authority
approval for various uses of its Omniferon product in the future. This approval
requires several years of clinical trials and substantial additional funds.
Until 1993, we did not operate actively because of limited funds. As a result of
funds previously raised by us as well as funds from the current transaction, we
are concentrating our efforts in obtaining approval for our Omniferon product
initially in the European Union and eventually from the Food and Drug
Administration for the United States.

         Our affiliate, Viragen (Scotland) Ltd., has entered into a license and
manufacturing agreement with the Common Services Agency of Scotland, and the
Scottish National Blood Transfusion Service. As a result of this agreement, the
Scottish National Blood Transfusion Service will help in the manufacture of
Viragen (Scotland)'s natural interferon product for exclusive distribution in
the European Union and on a non-exclusive basis worldwide. The Scottish National
Blood Transfusion Service will receive royalties and special access to our
Omniferon product. We have also entered into agreements with the American Red
Cross, America's Blood Centers and the German Red Cross for supplies of white
blood cells. These sources of white blood cells will enable us to manufacture
Omniferon in sufficient quantities to conduct planned European Union and United
States clinical trials and, subject to regulatory approvals, also provide for
commercial manufacturing in the future.

         Our executive offices are located at 865 S.W. 78th Avenue, Suite 100,
Plantation, FL 33324. Our telephone number is (954) 233-8746; our facsimile
number is (954) 233-1414.

We have a history of losses due to lack of sales and regulatory approval. Our
independent accountants have included a going concern explanatory paragraph in
their report

         Since the organization of Viragen, Inc., we have incurred operating
losses. The net loss for our fiscal year ended June 30, 1999 was $10,650,832. At
June 30, 1999, we had a total deficit since organization of $50,521,028 and a
working capital deficit of $2,290,441.

         We presently produce a single product known as Omniferon(TM), a natural
human leukocyte derived alpha interferon. However, because the United States
Food and Drug Administration and the European Union regulatory authorities have
not yet approved our natural interferon product, we cannot sell this product
and, therefore, have no current source of income from operations.

         We will not be able to reduce our losses or operate profitably until we
obtain the necessary approvals to sell natural interferon. While we currently
have a 10% interest in a separate product for the treatment of rheumatoid
arthritis, sales of natural interferon are expected to be our primary source of
income. Investors must understand that our natural interferon product may never
receive the necessary approvals from regulatory authorities. In addition, even
if approval is received, we may not be able to recover sufficient profit from
the sale of natural interferon. If we do not obtain the required approvals or
profit from the sale of natural interferon or other products, Viragen most
likely will be forced to terminate its operations. In that case, those who have
invested in Viragen will likely lose their entire investment.

         As a result of these conditions, our independent certified public
accountants included an explanatory paragraph in their report dated
September 17, 1999, indicating that these conditions raised substantial doubt
about our ability to continue as a going concern.


Viragen has recently been delisted from NASDAQ. If the penny stock rules become
applicable to our stock, it may become more difficult to sell our stock

         On June 28, 1999, the Nasdaq Stock Market delisted our common stock
because the hearing review panel was concerned that we would not be able to
maintain a closing bid price for our common stock of at least $1.00, as well as
continue to meet Nasdaq's minimum $4 million net worth requirement. As a result,
our common stock is now traded on the OTC Bulletin Board, which is a more
limited market than the Nasdaq Stock Market. Stocks quoted in this market
generally do not have the same following as stocks traded on the Nasdaq Stock
Market. Compared to stocks included in the Nasdaq Stock Market, OTC Bulletin
Board stocks are generally not quoted in the stock market tables in local and
national newspapers. In addition, our common stock could become subject to the
penny stock rules under the Securities Exchange Act of 1934, if we do not
maintain a minimum




                                       4
<PAGE>   8

tangible net worth of at least $2 million. As of June 30, 1999, our tangible net
worth totaled $3,836,259.

         The penny stock rules require broker-dealers, prior to a transaction in
a penny stock which is not exempt from the rules, to deliver a standardized risk
disclosure document prepared by the Securities and Exchange Commission that
provides information about penny stocks and the risks in the penny stock market.
The broker-dealer also must provide the customer with current bid and offer
quotations for the penny stock, the compensation of the broker-dealer and its
salesperson in the transaction, and monthly account statements showing the
market value of each penny stock held in the customer's account. The bid and
offer quotations, and the broker-dealer and salesperson compensation
information, must be given to the customer orally or in writing prior to
completing the transaction and must be given to the customer in writing before
or with the customer's confirmation.

         In addition, the penny stock rules require that prior to a transaction
in a penny stock which is not exempt from the penny stock rules, the broker
and/or dealer must make a special written determination that the penny stock is
a suitable investment for the purchaser and receive the purchaser's written
agreement to the transaction. These disclosure requirements may have the effect
of reducing the level of purchases in our common stock and trading activity in
the secondary market for Viragen's common stock. If our common stock becomes
subject to the penny stock rules, it will be more difficult for you to sell the
common stock which may reduce the value of your investment.


Competition in pharmaceutical industry in products offered and for funding may
force us to terminate operations

         Competition for investment capital and market share in the
immunological and pharmaceutical products industry is very strong. Our
competitors, which include major pharmaceutical companies, have more experience
in research, development and clinical testing of pharmaceutical and biomedical
products. Our competitors also have greater financial, marketing and human
resources than Viragen. Some of our competitors, including Hoffman-La Roche,
Inc., Shering-Plough Corporation, Biogen, Inc., Chiron Corp., and Baxter
Laboratories , already have approvals for their synthetic interferons and since
1986 have been marketing their products. These companies have received wide
acceptance from the medical community and the patient population for their
products. This will make it more difficult for us once we are able to introduce
our product. Competition is only expected to increase in the future. In
addition, technological advances made by our competitors may make synthetic
products more effective, less costly and with less harmful side effects. Viragen
may not be able to keep pace with technological advances by others, either
because we do not have sufficient resources or because we cannot achieve greater
improvements in our technology. If we are unable to compete with out larger,
more experienced competitors, we may be forced to terminate operations.

         Competition for funding in the pharmaceutical industry is also intense.
As explained above, we have no source of income and may not have sufficient
sources of income or investment capital for a significant period of time, if
ever. Additional funds will be needed to conduct clinical trials so we can
receive regulatory approvals. We must obtain additional funding from outside
sources



                                       5


<PAGE>   9

to conduct these trials. In the event we are unable to locate funding or obtain
funding on reasonable terms, we will most likely be required to terminate
operations. In that case, any investment in Viragen would be lost.


Government regulation may affect Viragen's ability to develop and distribute
natural interferon

         All pharmaceutical manufacturers are subject to state and federal rules
and regulations. In particular, we must comply with the United States Food and
Drug Administration guidelines governing the productivity, testing and
marketing. European Union regulatory authorities also impose regulations. These
rules and regulations are constantly changing. These changes could extend the
period of clinical trials, involve costly compliance measures and may restrict
our ability to produce and distribute our natural interferon product based on
the results of testing. It is possible that we may never receive these
regulatory approvals for any specific illness or for the range of illnesses that
we are attempting to treat with our natural interferon product.


If patients have problems receiving third party reimbursements of our product it
will be more difficult to market our product. In addition, our marketing costs
would increase.

         Our ability to successfully market our products depends in part on the
receipt of reimbursements from government health administration authorities,
private health coverage insurers and other organizations. The pricing of
products similar to those we produce or the amount of reimbursement available
from governmental agencies or third party insurers may affect our ability to
market our product or market our product at a profit. This is so because
limitations on third party reimbursements could restrict the patient population
that will make use of our product. Difficulties in getting third party payors to
allow reimbursement for our product could also require us to increase our
marketing efforts which will involve greater expenses.


Our proprietary technology and any future patents that we receive may not
provide sufficient protection to us

         We intend to rely, in part, on our internally developed technology for
the efficient and safe production of natural interferon that was developed by
Viragen's scientists. We believe that this technology allows us to produce our
natural interferon more efficiently and with less possible contaminants making
it a more desirable and affordable product. Viragen recently filed two patent
applications relating to our Omniferon production technology. If in fact, we are
not successful in obtaining patents or demonstrating that our production process
is proprietary under trade secret law, we will have limited protection from
those who might copy our technology. In addition, we may be damaged if we are
accused of misappropriating a competitor's proprietary technology even if these
claims are untrue. We cannot assure you that our patent applications will be
approved, and if granted, that these patents or our other proprietary rights
will provide necessary protection to us.

<PAGE>   10

Technology transfers by Viragen to third parties may not result in revenue to us

         One of our proposed marketing strategies is to license the right to
used our technology and product manufacturing techniques to third parties, who
will in turn use them to produce natural human leukocyte alpha interferon
outside the United States. We cannot guarantee that we will be able to
successfully market the product or receive revenue from their efforts.


We may be exposed to product liability claims and our product liability
insurance may not be sufficient to cover all claims or continue to be available
to us

         We may be subject to claims for personal injuries or other damages
resulting from the use of our natural interferon. In order to protect Viragen
against these claims, we maintain product liability insurance in the amount of
$1,000,000 per occurrence and $2,000,000 in total. We cannot be sure that this
insurance will be adequate to cover any liabilities that may result from the use
of our natural interferon or that we will be able to afford this form of
insurance in the future.


Our reliance on foreign third party manufacturer may disrupt operations

         Viragen (Scotland) Ltd., a wholly-owned subsidiary of Viragen (Europe)
Ltd., our majority-owned subsidiary, entered into a manufacturing agreement with
the Common Services Agency of Scotland for the production of Omniferon, our
natural interferon product. Under this agreement, Viragen (Scotland) Ltd. and
the Common Services Agency of Scotland will jointly manufacture Omniferon. Our
decision to use an offshore manufacturer could expose Viragen (Scotland) to
risks involved with fluctuations in exchange rates of foreign currencies. In
addition, relying on the Common Services Agency of Scotland exposes us to all
the risks of dealing with a foreign manufacturing source. These include
governmental regulations, tariffs, import and export restrictions,
transportation, taxes and foreign health and safety regulations.

         Foreign manufacturing arrangement will limit our control and may lead
to the disruption of our operations which could negatively affect our operations
and your investment in us.


We are dependent on certain key executives and their loss would be damaging to
Viragen

         Our day-to-day operations are managed by Mr. Gerald Smith, our chairman
of the board and president, Mr. Dennis W. Healey, our executive vice president,
treasurer and chief financial officer, and Dr. D. Magnus Nicolson, the managing
director of Viragen (Scotland) Ltd. We have employment agreements with Messrs.
Smith, Healey and Nicolson which restrict competitive activities by them during
the term of their agreements and for a two-year period thereafter. However, the
loss of their services would have a negative effect on our ability to conduct
business. Our future success will greatly depend on our ability to attract and
retain additional skilled personnel in various phases of our operations.


Our transaction with selling security holders may cause substantial dilution to
our shareholders

         We expect to issue up to 6,220,121 shares of our common stock, or 8.2%
of the issued and outstanding common stock as of September 24, 1999, to the
selling security holders in



                                       7

<PAGE>   11
connection with the notes and warrants described in this prospectus. The selling
security holders could invest additional funds in Viragen on terms virtually
identical to those described in the "Selling Security Holders" section of the
prospectus for up to an additional $7,000,000, which will include substantially
the same conversion terms and penalty provisions. However, neither we nor the
selling security holders are obligated to sell or purchase any securities in the
future. Due to the large percentage of shares of our common stock we may sell to
the selling security holders, you may experience substantial dilution of your
investment in us. In addition, sales of our shares by the selling security
holders may depress the price of our stock in the market. Future transactions
with the selling security holders or any other investors could further depress
the price of our stock. We will require additional funding to conduct
operations. This funding may not be available and will involve further dilution
to investors.


Possible payment of penalty fees to selling security holders could negatively
affect our operation

         As described later on in the "Selling Security Holders" section of this
prospectus, we may be obligated to pay the selling security holders penalty fees
in excess of the amount of their investment if we default on our obligations to
the selling security holders. Triggering events include default under the
promissory notes, failure to maintain effectiveness of our registration under
the Securities Act of 1933, delisting our stock from Nasdaq (which has
occurred), and failure to have our registration statement become effective by
July 7, 1999 (which has occurred). These penalties involve payments of many
thousands of dollars which depends on the period that we are in non-compliance.
To date, we have incurred approximately $160,000 in penalty fees. The penalty
amount will continue to increase $40,000 per month, until this registration
becomes effective. If we are required to pay the penalty fees, our ability to
finance our current and future operations could be negatively affected.



Our operations may suffer from computer problems relating to the year 2000

         Many existing computer programs use only two digits to identify a year
in the date field. These programs were designed and developed without
considering the impact of the upcoming change in the year 2000. Some older
computer systems store dates with only a two-digit year with an assumed prefix
of "19." Consequently, this limits those systems to dates between 1900 and 1999.
If not corrected, many computer systems and applications could fail to create
erroneous results by or at the year 2000.

         Because we will rely heavily on computers to conduct our business, we
are subject to all the risks associated with the year 2000. We have assessed the
scope of our risks related to problems these computer systems may have related
to the year 2000 and we believe these risks have been addressed. In addition, we
are in the process of questioning our vendors and business partners about their
progress in identifying and addressing problems related to the year 2000.
However, we cannot assure you that all of these third party systems or our
computer systems will be year 2000 compliant.




                                       8

We will require additional funding to conduct operations. The funding may not be
available and will involve further dilution to investors

         Viragen will continue to require significant funding in the future to
continue its operations. In addition to the $2,000,000 received from the selling
security holders in the transaction described in this prospectus, the selling
security holders and Viragen may conclude similar arrangements for up to an
additional $7,000,000 in funding. However, neither Viragen nor the selling
security holders have the obligation to complete the financing for the
additional $7,000,000 in funding. We cannot assume that this additional
financing or any additional financing will be available. Given the large amount
of funding required by Viragen in the future, any financing will involve the
issuance of millions of shares of capital stock of Viragen and substantial
dilution to our investors.


We do not expect to pay dividends in the foreseeable future

         We have never paid cash dividends on our common stock and do not expect
to pay cash dividends on our common stock any time in the near future. The
future payment of dividends directly depends upon our future earnings, capital
requirements, financial requirements and other factors to be determined by our
board of directors. For the foreseeable future, any earnings from operations
will be used to finance our growth and will not be paid to our common
stockholders in the form of dividends. Since we do not anticipate paying cash
dividends on our common stock, return on your investment, if any, will depend on
an increase in the market value of Viragen's common stock.


Possible sales of securities by current stockholders and depressive effect on
market value of our stock

         As of September 24, 1999, we had 12,058,032 shares of common stock
outstanding which were "restricted securities" as that term is defined by Rule
144 under the Securities Act of 1933, as amended. As of September 24, 1999, we
had convertible preferred stock, options and warrants outstanding which if
exercised would result in 10,059,154 additional shares of our common stock
outstanding. The shares of common stock outstanding do not include shares of
common stock that may be issued on conversion of various options and warrants.
Under Rule 144, a person who holds restricted securities for a period of one
year may sell a limited number of shares to the public in ordinary brokerage
transactions. Sales under Rule 144 and sales of common stock covered by
registration statements filed by us including shares covered by this prospectus
may reduce the market price of our common stock and increase the number of our
publicly-held securities.


Use of preferred stock could be used to resist takeovers and may also cause
potential additional dilution

         Our Certificate of Incorporation authorizes 1,000,000 shares of
preferred stock, of which at September 24, 1999, 2,650 shares of series A
preferred stock and 11 shares of series I preferred stock were issued and
outstanding. Our Certificate of Incorporation gives our board of directors the
authority to issue preferred stock without approval of our stockholders. We may
issue additional shares of preferred stock to raise money to finance our
operations. We may authorize issuance of



                                       9

<PAGE>   13

the preferred stock in one or more series. In addition, we may set the dividend
and liquidation preferences, voting rights, conversion privileges, redemption
terms and other privileges and rights of the shares of each authorized series.
The issuance of large blocks of preferred stock could possibly have a dilutive
effect to our existing stockholders and negatively impact our existing
stockholders' liquidation preferences. In addition, while we include preferred
stock in our capitalization to improve our financial flexibility, we could
possibly issue our preferred stock to friendly third parties to preserve control
by present management in the event we become subject to a hostile takeover that
could ultimately benefit Viragen and Viragen's stockholders.

                                 USE OF PROCEEDS

         Viragen received $1,861,820, net of finders' fees, from the sale of the
convertible notes with detachable warrants. We may receive additional proceeds
upon the exercise of the warrants. We will not, however, receive any proceeds
from the sale of shares of common stock acquired by the selling security
holders.

         Proceeds received by Viragen will be used to fund operations.

                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY

     Viragen's common stock traded on the NASDAQ National Market between
December 29, 1996 and June 28, 1999, under the symbol "VRGN". Our common stock
commenced trading on the over-the-counter bulletin board on June 29, 1999. The
stock symbol continues to be "VRGN". The following table sets forth the high and
low bid quotations for our common stock since July 1, 1997.

     These quotations represent prices between dealers, and do not include
retail mark-ups, markdowns or commissions, and may not necessarily represent
actual transactions.

     As of October 6, 1999, we had approximately 2,700 stockholders of record.
At that date, the closing price of the common stock was $0.68 per share.

     We have not paid any dividends on our common stock since incorporating in
1980. Since we have experienced losses since inception, have significant capital
requirements in the future and presently intend to retain future earnings, if
any, to finance the expansion of our business, it is not anticipated that we
will pay any cash dividends in the foreseeable future. Future dividend policy
will depend on our earnings, if any, capital requirements, expansion plans,
financial condition and other relevant factors.

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

     The statements contained in this report on Form S-1 that are not purely
historical are forward looking statements within the meaning of Section 27A of
the Securities Act of 1933 and Section 21E of the Securities and Exchange Act of
1934. These include statements regarding Viragen's expectations, hopes,
intentions, beliefs, or strategies regarding the future. Forward looking
statements include our statements regarding liquidity, anticipated cash needs
and availability, and anticipated expense levels in "Management's Discussion and
Analysis of Financial Condition and Results of Operations" including expected
product clinical trial commencement dates, product introductions, expected
research and development expenditures and related anticipated costs. All forward
looking statements included in this document are based on information available
on this date, and we assume no obligation to update any of our forward looking
statements. You should note that actual results could differ materially from
those contained in forward looking statements. Among the factors that may cause
our actual results to differ materially are the following factors and the risks
discussed in the "High Risk Factors" section included in this prospectus.

     The biopharmaceutical industry is highly competitive and subject to rapid
technological change. Significant competitive factors in the pharmaceutical and
biopharmaceutical markets include product efficacy, price and timing of new
product introductions. Increased competition from existing biopharmaceutical
companies as well as the entry into the market of new competitors could
adversely affect the our financial condition or results of operations.

     Our future success depends in part upon our intellectual property,
including patents, trade secrets, know-how and continuing technological
innovation. We cannot provide assurances that any steps we take to protect our
intellectual property will be adequate to prevent misappropriation or that
others will not develop competitive technologies or products. We cannot offer
any assurances that any current or future patent, if any, owned by us will not
be invalidated, circumvented or challenged, that the rights granted to us will
provide competitive advantages or that any future patent applications will be
issued within the scope of the claims sought by us, if at all. Furthermore, we
cannot assure you that others will not develop technologies that are similar or
superior to ours, duplicate our technology or design around any patents held by
us.

     Viragen has incurred operational losses and operated with a negative cash
flows since its inception in December 1980. Losses have totaled $10,650,832,
$7,856,136, and $4,775,245 for the fiscal years ended June 30, 1999, 1998 and
1997, respectively.

LIQUIDITY AND CAPITAL RESOURCES

     As of September 24, 1999, Viragen has limited capital to sustain its
operations. The fiscal 1999 report of independent certified public accountants
noted our financial condition raises substantial doubt as to our ability to
continue as a going concern. We are actively seeking new investment capital;
however, we cannot assure you as to the timing of any new investment, if at all.
If we are unable to attract new investment capital in the near-term, it would be
necessary for us to significantly reduce or completely suspend all operations.

     Viragen had a working capital deficit of approximately $2,290,000 at June
30, 1999, a decrease in working capital of $10,133,000 from the previous year.
This decrease was due to operational losses of $10,650,832, cash disbursements
of $1,100,000 for the purchase of an equity interest in Inflammatics, Inc. and
additions to


                                       13

<PAGE>   17

property, plant and equipment of approximately $497,000 during the year. The
reductions in working capital were off-set by $1,375,000 in proceeds raised
through an equity offering.

     On March 17, 1999, we entered into a purchase agreement with the Isosceles
Fund Limited and Cefeo Investments Limited, which was amended on June 16, 1999.
Under the purchase agreement, we issued Isosceles and Cefeo 8% convertible
promissory notes in the aggregate principal amount of $2,000,000 and warrants to
purchase shares of our common stock. At the same time we executed the purchase
agreement, we entered into a memorandum of agreement with Isosceles which gives
us the opportunity to sell Isosceles an aggregate of up to $7,000,000 of
additional notes and warrants in two tranches. Neither Viragen nor these
security holders have an obligation to complete the subsequent tranches.

     One-half of the principal balance and accrued interest on the
notes automatically converted into 2,049,534 shares of our common stock on
July 7, 1999. The remaining one-half of the principal balance and accrued
interest on the notes automatically converted on August 6, 1999 into 2,062,685
shares of our common stock. The conversion price on both conversions was the
lesser of $0.50 or the lowest closing bid price of our common stock during the
ten consecutive trading days immediately preceding each of the conversion dates.
The notes were converted at $.50 per share.

     In addition to the shares issued on conversion of the notes, the note
holders were entitled to receive additional shares of our common stock 30 days
after each one-half of the notes converted into common stock, as required by a
reset provision. The purpose of this arrangement was to ensure that the
investors had a return

                                       14
<PAGE>   18

of at least 20% on the shares received on the conversion of the first half of
the notes and at least a 22% return on the conversion on the remaining half of
the notes.

     As a result of this provision, we issued 546,990 shares and 551,203 shares
under the first and second reset, respectively.

     The warrants entitle Isosceles and Cefeo to purchase an aggregate of
932,039 shares of our common stock. The warrants are exercisable until March 17,
2004. The warrants are exercisable at $0.50 per share. The warrants also contain
a cashless exercise provision which allows the selling security holders to use
the difference between the closing price of the common stock at the time of
exercise, minus the exercise price, as a currency to acquire the shares without
paying cash. By way of example, if 1,000 shares are being exercised when the
closing price is $1.00 and the exercise price is $.50, the selling shareholders
could use 500 shares with a market value of $500 to pay for the exercise of the
warrants. The holder would receive 500 shares net, as a result of the cashless
exercise.

     We must, however, reduce the exercise price of the warrants if we were to
sell shares of our common stock, grant options or adjust the exercise prices of
options or issue other securities convertible into our common stock at prices
less than $.50.


                                       15

     In May 1999, we completed a private placement for the sale of 2,750,000
shares of common. The common shares were sold to three accredited investors with
whom we have had prior dealings, at $0.50 per share. Viragen received proceeds
of $1,375,000 from the sale of these shares.




                                       16

     In November 1998, Viragen signed an exclusive supply and distribution
agreement with AGC, a Pakistan-based, multinational conglomerate, for the
purchase and distribution of Omniferon. Under this agreement AGC's designated
territories include Saudi Arabia, Kuwait, Yemen, Oman, UAE, Brunei and other
Middle Eastern countries, as well as India and Pakistan. The AGC agreement calls
for AGC to purchase a minimum of $20 million of Omniferon over five years. The
agreement is subject to AGC's receipt of the required regulatory approvals for
product commercialization in the designated territories and our receipt of the
requisite regulatory approvals to export Omniferon from our commercial
manufacturing facility in Edinburgh, Scotland. AGC agreed to secure the purchase
minimums with a $1 million irrevocable revolving letter of credit. The purchase
minimums increase significantly if and when we obtain regulatory approval for
commercialization of Omniferon in the United States and/or Europe.

     Under the terms of the AGC agreement, AGC is responsible for clinical and
regulatory costs to obtain approvals for commercialization of Omniferon in its
designated territories and all subsequent sales, marketing and distribution
activities in these regions. The AGC agreement also calls for AGC to build, own
and operate, at its own expense, a pharmaceutical distribution facility in a
mutually agreeable location within the designated territories. AGC has informed
us that they will initially focus on the distribution for hepatitis B and C,
diseases which are at epidemic proportions in the designated territories.

     In July 1999, Viragen entered into a letter of intent with Drogsan
Healthcare, a Turkish pharmaceutical company. The letter of intent outlines the
terms of a supply and distribution agreement between Viragen and Drogsan for
natural interferon, under terms similar to the AGC agreement. The final terms of
this agreement are still being negotiated.

     In August 1998, we entered into a strategic alliance simultaneously with
our purchase of a 10% equity interest in Inflammatics, Inc., a private drug
development company headquartered in Philadelphia, PA. Inflammatics is focused
on the development of therapeutic drugs for autoimmune disorders. Its lead
product is LeukoVAX, an immunomodulating white blood cell preparation currently
in Food and Drug Administration Phase I/II clinical trials for rheumatoid
arthritis.

     Under the terms of the Inflammatics agreement, we made an initial
investment in the form of series A convertible preferred stock of Inflammatics
for $1 million and warrants to purchase 250,000 shares of our common stock at
prices ranging between $1.00 and $1.78 per share. In addition we obtained two
options to acquire an additional 70% equity position in Inflammatics through two
additional fundings to be made at our option. The first additional funding,
subject to our evaluation of the Phase I/II clinical trial results, provides for
the issuance of 1,000,000 shares of common stock, the issuance of 300,000 common
stock purchase warrants exercisable at $1.00 through August 14, 2003, and the
underwriting of Phase III clinical trials, in exchange for an additional 36.3%
equity interest. Preliminary estimates for the funding of Phase III clinical
trials of LeukoVAX range between $6.0 million and $10.0 million. The second
additional funding, subject to our further evaluation of the Phase III clinical
trial results, provides for the issuance of an additional 2,000,000 shares of
common stock in exchange for an additional 33.3% equity interest.

     Additional funding will be required to complete the clinical trial process
relating to Omniferon both in the European Union and domestically prior to
receiving regulatory approval to market the product. Anticipated funding
requirements related to approval of Omniferon for hepatitis C, the first
approval we are seeking includes: Phase I and Phase II trials -- $3.2 million
and Phase III studies -- $9.1 million. In addition, our anticipated funding
requirements for U.S. operations include: the establishment of domestic
manufacturing capacity -- $6 million; and joint research and development
projects -- $4 million. Additional funding will also be required to complete
Phase III studies in the U.S. New funding will also be used for continued
product development, general working capital purposes including administrative
support functions and the possible equity investments in businesses
complementary to the our operations.

     Management believes that our Omniferon product currently under development
can be manufactured in sufficient quantity and be priced at a level to offer
patients an attractive alternative to currently available treatments for
illnesses such as hepatitis C. However, to maintain our current level of
operations including our production scale up projects for Omniferon currently
being conducted in our facility in Scotland and to commence our clinical trials
as planned, we will need to raise significant additional working capital from
outside sources. If we are unable to locate this additional funding we would
most likely be forced to terminate operations or significantly reduce our
operations.

     While subject to significant limitation, at June 30, 1999 Viragen has
available approximately $31.3 million in net tax operating loss carryforwards
expiring between 2000 and 2019. These carryforwards may be used to offset
taxable income, if any, during those periods. Our ability to generate revenues
during future periods is dependent upon receiving regulatory approvals for our
Omniferon and/or LeukoVAX products. As we cannot be certain that we will receive
the necessary regulatory approvals, we are unable to conclude that realization
of benefits from our deferred tax assets is "more likely than not", as
prescribed by SFAS 109. Accordingly, we are recognizing a valuation allowance to
offset 100% of the deferred tax assets related to these carryforwards.

     Currently, we believe that our foreign currency risk is not material. At
the present time, we do not have sales revenue or related receivables. Also, we
do not purchase foreign currencies on a regular basis. Transfers of funds to our
foreign subsidiaries are performed infrequently, in large sums, at the
then-current exchange rates.

     To date we have not been impacted by the European Union's adoption of the
"Euro" currency. Our foreign operations are located in Edinburgh, Scotland, and
the United Kingdom did not participate in the adoption of the Euro. The United
Kingdom does not have a scheduled date for the eventual adoption of the Euro.

RESULTS OF OPERATIONS

     As the discussion of Liquidity and Capital Resources noted, our fiscal 1999
report of independent certified public accountants noted our financial condition
raises substantial doubts as to our ability to continue as a going concern.

     Viragen recognized no sales revenue or related costs for the fiscal years
ended June 30, 1999, 1998, or 1997. We have limited potential for sales prior to
receiving the necessary regulatory approvals from the U.S. Food and Drug
Administration and/or comparable European authorities. We could commence
generating sales revenue through export sales of Omniferon, under the AGC
Agreement. These sales, however, are contingent upon AGC's receipt of the
required regulatory approvals for product commercialization in the designated
territories, and our receipt of the requisite regulatory approvals. While we did
receive approval of our Clinical Trial Exemption Application from the European
Union regulatory authorities to begin clinical trials of Omniferon, our
multi-species natural human leukocyte-derived alpha interferon, we have not yet
begun these trials. We intend to commence clinical trials in the European Union
during the fourth calendar quarter of 1999 and eventually submit an
Investigational New Drug Application to the Food and Drug Administration. We
cannot assure you we will receive these approvals. These approvals are subject
to the successful completion of clinical trials and our ability to raise
significant additional investment capital to fund the completion of these
trials.

  1999 Compared to 1998

     The significant decline in interest and other income for 1999, compared to
the previous year reflects the reduction in cash balance invested between
periods. This reduction results primarily from operational losses, the cash
investment in Inflammatics, Inc., and expenditures associated with expansion of
our laboratory and manufacturing facility in Scotland.

     Research and development costs totaled approximately $5,153,000 for the
fiscal 1999 compared to $4,222,000 for the same period of the previous year. The
increase of $931,000 (22%) included an increase in research related salaries and
support fees of $468,030, and an increase in equipment maintenance costs of
$127,988. We also recognized $136,021 in compensation expense on warrants issued
to scientific consultants, under the guidelines of FAS 123, not incurred in the
prior year. The bulk of our development work is now being done in our Scottish
facility. Research and development costs can be expected to continue to increase
in following periods as we commence clinical trials of Omniferon.

     General and administrative expenses totaled approximately $5,528,000 for
the current year, a decrease of approximately $52,000 from the preceding year.
During 1999, we waived a 90-day expiration provision on stock options held by
three directors who were not re-elected to the board of directors and recognized
$171,875 in compensation expense as a result of the modified grants. We also
recognized $61,751 in compensation expense on warrants issued to consultants
during the year. Overall, compensation expense from

                                       18
<PAGE>   22

stock options and warrants increased by $176,000 compared to the prior year.
These increased expenses were offset by a decrease in insurance costs of $93,689
from the prior year due to favorable rates obtained on policy renewals. We also
experienced a decrease of $222,600 in legal fees between periods due to the
settlement of litigation during the prior year, as well as the completion of
contract negotiations. We expect general and administrative expenses to decrease
during the upcoming year as domestic administrative staff and related costs have
been reduced by approximately $1.3 million commencing in June, 1999.

     During the year we recognized approximately $757,000 in losses related to
our investment in Inflammatics, Inc. This loss reflects 100% of the losses
incurred by Inflammatics associated with the clinical testing of LeukoVAX, as
well as the expensing of our excess investment costs.

     Our management anticipates operational losses will continue increasing, as
we begin planned clinical trials of Omniferon. In January 1999, we began
implementing a cost-reduction plan. Planned cost reduction is expected to save
approximately $2.4 million annually in operating expenses. The reductions
include the elimination of administrative and research positions in the U.S.
saving approximately $1.6 million. We also plan on closing our Florida-based
research facility, consolidating these operations in our Scottish facility and
saving approximately an additional $800,000 annually. The changes in operations
reflect the shift from developing Omniferon in our domestic laboratories to
scale-up development and conducting clinical research in the European Union. As
a result, while significant savings will be realized in the US, particularly in
general and administrative expenses, these savings will be more than offset by
increasing expenses incurred in our Scottish facilities related to scale-up
process and the start of clinical trials. Clinical trials are expected to
commence in the forth calendar quarter of 1999.

  1998 Compared to 1997

     Interest and other income of $1,143,112 represented earnings on invested
cash balances during the year and reflect a 19% decline from the previous fiscal
year. This significant decline reflects the decline in cash balance from the
previous year. This decline was due primarily to cash redemption on convertible
preferred stock issuance and operational losses. This trend is expected to
continue into the next fiscal year.

     Research and development costs totaled $4,222,332, for fiscal 1998 compared
to $2,360,416 for the previous year. This increase reflects the overall increase
in research activities being conducted between the periods both in the U.S. and
Scotland, related primarily to the scale-up of our manufacturing technology in
the Scottish manufacturing facility. Components of this increase included
increases in laboratory supplies expense of $466,900, increases in research
related salaries and support fees of $440,100, an increase in research related
scientific professional fees paid to the Transfusion Service of $200,100,
increased consulting and outside laboratory testing of $208,400, and increased
travel related expenses associated with the transfer of technology and process
development between our Florida and Scottish facilities. Research and
development costs associated with Omniferon process development projects are
expected to increase during the next fiscal year as process scale-up research
nears completion. While process development costs are expected to decline in the
following fiscal year, these reductions will be offset by costs associated with
clinical trial expenditures.

     Selling, general and administrative expenses totaled $5,580,213 for fiscal
1998, reflecting an increase of $1,531,127 (38%) over the preceding year. This
increase included increases in administrative salaries and related taxes of
$599,400. This increase was due primarily to the addition of administrative
staff in our Florida facility and domestic salary increases. We also recognized
increases in rent expense commencing in August 1997 related to our new
administrative facility in Plantation, Florida and the expansion of leased space
in our Scottish manufacturing facility. Total rent expense for our facilities
increased by $393,600 over the prior year. Legal fees between the periods have
increased by $559,000 due to increases in fees associated with research of
technology patents of $111,300, expanded efforts in collaborative agreements and
general contractual transactions, both domestically and in Europe, of $211,200
and increased costs associated with litigation of $222,900. We also recognized
$109,900 in bad debt expense attributable to a director loan with related
accrued interest. These increases were offset by compensation expense in the
prior year of $396,500 attributable to the issuance of options, which was not
incurred in fiscal 1998, and a decrease of $250,391 in

                                       19
<PAGE>   23

losses on the settlement of litigation. During the prior year, we settled
threatened litigation for $288,245. The potential litigation stemmed from
allegations of a former Cytoferon Corp. shareholder claiming compensation due
under a consulting agreement entered into with Cytoferon Corp. While Cytoferon
Corp. and Viragen denied any wrong doing in this matter, it was believed that
the settlement, through the issuance of treasury shares, would prove less costly
to us. We have also experienced increased travel costs attributable to
administrative support functions related to the establishment of our Scottish
facility. General and administration expenses are expected to remain relatively
stable over the next fiscal year, as we have no plans to add to its
administrative staff with related costs. We also expect that legal fees
associated with litigation and due diligence efforts may decline.

     Interest expense totaled $590,867 for fiscal 1998, reflecting a significant
increase over the preceding year. This increase was due primarily to interest
expense attributable to the 10% $9,720,240 note payable issued in July 1997 in
exchange for the series B convertible stock then outstanding. This note was
paid-in-full in April 1998.

YEAR 2000

     Viragen recognizes the potential problems posed to operations by its
dependence upon date sensitive computer systems and applications throughout its
business and the operations of third parties upon whom we are dependent. We rely
heavily on computerized laboratory equipment both for our ongoing research and
production scale-up projects as well as computer controlled commercial scale
manufacturing equipment in place in our Scottish facility. In addition, through
strategic alliance and supply agreements currently in place, we are also
dependent upon Year 2000 compliance by third parties for the supply of critical
raw materials as well as certain manufacturing steps and storage of products
produced for planned clinical trials and eventually for commercial scale
production.

     We have been using both internal and external resources to isolate and as
necessary, reprogram, update or replace hardware or software found to be non
Year 2000 compliant. The evaluation phase of our Year 2000 compliance program
began in the fourth quarter of fiscal 1998. Due to the limited size of our
administrative staff, it is expected that most of this work will be performed by
outside contractors retained specifically for this project. We expect to
complete our internal Year 2000 project by October 1999. The total estimated
cost for us to complete our internal Year 2000 project is $50,000 to $70,000,
including projected hardware replacements indicated. Funding for the evaluation
and corrective phases is being provided from general working capital.

     We have contacted certain external third parties, including raw material
vendors and scientific equipment manufacturers considered critical to our
current and planned future operations to discuss and evaluate their own
compliance programs. After we complete our evaluation of third party responses,
we will prepare a contingency plan to mitigate third party Year 2000 issues, if
necessary.

     The costs and projected completion dates of our Year 2000 compliance
program is based on our best estimates and is dependent in large part upon
compliance programs of external third parties or scientific equipment and
software vendors over whom we have no direct control. Accordingly, our inability
or the inability of critical vendors to meet Year 2000 compliance deadlines
could have a material adverse impact on our operations from a product
development, clinical trial or commercial manufacturing standpoint, negatively
affecting our financial condition, results of operations and cash flows.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     On January 28, 1997, the Securities and Exchange Commission adopted
Securities Act Release No. 7386 which requires that we disclose our policies
used to account for derivatives and certain quantitative and qualitative
information about market risk exposures. Market risk generally represents the
risk of loss that may result from the potential change in value of a financial
instrument as a result of fluctuations in interest rates and market prices.

     We have not traded or otherwise transacted in derivatives nor do we expect
to do so in the future. We have established policies and internal processes
related to the management of market risks which we use in the normal course of
our business operations.

     Interest Rate Risk

     The fair value of long-term interest rate debt is subject to interest rate
risk. As we had a minimal amount of long-term debt at June 30, 1999, a change in
interest rates would not have a material impact on our future operating results
or cash flows.

     Foreign Currency Exchange Risk

     We believe our foreign currency risk is not material. At the present time
we do not have sales revenues or related receivables. Also, we do not purchase
foreign currencies on a regular basis. Transfers of funds to our foreign
subsidiary in Scotland are infrequent and are transferred at the then current
exchange rate.

     We were not impacted by the European Union's adoption of the "Euro"
currency. Our foreign operations are located in Scotland and the United Kingdom
did not participate in the adoption of the Euro. The United Kingdom does not
have a scheduled date for the eventual adoption of the Euro.

                                    BUSINESS

INTRODUCTION

     Viragen, Inc. was organized in 1980 and is in the business of researching
and developing products which help the human immune system resist viral
infections. Our primary product is a natural interferon product named
Omniferon(TM) which is produced from human white blood cells. Natural interferon
stimulates and controls the human immune system. In addition, interferon may
stem the growth of various viruses including those involved with diseases such
as hepatitis, multiple sclerosis, certain cancers and HIV/AIDS.

     Our product has not been approved by the United States Food and Drug
Administration or the European Union regulatory authorities. Viragen will seek
Food and Drug Administration and European Union regulatory authority approval
for various uses of its Omniferon product in the future. This approval requires
several years of clinical trials and substantial additional funds. Until 1993,
we did not operate actively because of limited funds. Using funds raised in a
series of equity financings, we are concentrating our efforts in obtaining
approval for our Omniferon product initially in the European Union and
eventually from the Food and Drug Administration for the United States.

     Our affiliate, Viragen (Scotland) Ltd., entered into a license and
manufacturing agreement with the Common Services Agency of Scotland and the
Scottish National Blood Transfusion Service. As a result of this agreement, the
Blood Transfusion Service will help in the manufacture of Omniferon for
exclusive distribution in the European Union and on a non-exclusive basis
worldwide. The Blood Transfusion Service will receive royalties and special
access to our Omniferon product. We have also entered into agreements with the
American Red Cross, America's Blood Centers and the German Red Cross for
supplies of white blood cells. These sources of white blood cells will enable us
to manufacture Omniferon in sufficient quantities to conduct planned European
Union and United States clinical trials and, subject to regulatory approvals,
also provide for commercial manufacturing in the future.

     In August 1998, we acquired a 10% equity interest, with an option to
acquire up to an 80% interest, in Inflammatics, Inc. Inflammatics obtained a
license to the rights to LeukoVAX, also a human blood derived natural product,
for the treatment of rheumatoid arthritis. LeukoVAX is currently in U.S. Food
and Drug Administration Phase I/II clinical trials.

     We intend to obtain Food and Drug Administration and European Union
approvals for various uses of our Omniferon and LeukoVAX in the future.
Approvals will require several years of clinical trials and substantial
additional funding. To date, we have not commercially distributed either
product, although we did manufacture Alpha Leukoferon(TM), our first generation
natural interferon product, which was distributed for research purposes under a
limited Florida investigatory license and protocols program which was
discontinued in August 1995. Following August 1995, we did distribute on a
limited basis for patients approved by the Florida HRS for humanitarian purposes
under an HIV/AIDS study protocol conducted at no charge to patients.

     Currently we are concentrating our efforts on preparing for clinical trials
necessary to obtain approvals for Omniferon, initially within the European
Union, and later, in the United States. We commenced our preclinical studies
with Omniferon in March 1998 and obtained approval of our Clinical Trial
Exemption Application in July 1999. We plan to commence clinical trials of
Omniferon, in Europe, during the fourth calendar quarter of 1999.

RECENT DEVELOPMENTS

     To secure reliable and safe sources of human white blood cells, also known
as leukocytes or buffy coats, critical to the production of both Omniferon and
LeukoVAX, we have entered into a series of strategic alliance and supply
agreements with major worldwide suppliers of blood products. During 1998, we
entered into agreements with the American Red Cross and America's Blood Centers,
which between them collect annually


                                       21

<PAGE>   25

a substantial majority of the U.S. blood supply. We also entered into a series
of agreements covering a majority of the blood supply in Germany, a major
European supplier.

     In July 1998, we entered into a strategic alliance and supply agreement
with America's Blood Centers for the supply of human white blood cells.
America's Blood Centers is a national network of non-profit, independent
community blood centers operating in 45 states. America's Blood Centers members
annually collect in excess of 45% of the U.S. blood supply through member blood
donation centers and mobile collection facilities. Under the terms of the
America's Blood Centers agreement, we were granted first and preferential access
to all leukocytes produced by America's Blood Centers members who have elected
to participate in the program. We agreed to pay a fixed cost per leukocyte
provided during the first two years of the agreement. After the first two years,
the price may vary based upon incremental costs incurred by participating
America's Blood Centers members.

     In addition to cost reimbursement for leukocytes provided, the America's
Blood Centers agreement provides for a royalty payment to be paid for each
leukocyte provided under this agreement. The royalty to be paid is based on the
higher of:

     - a percentage of net revenues realized by Viragen

     - the estimated net revenues that could have been realized, based on the
       sale of Omniferon, utilizing the America's Blood Centers leukocytes
       provided, or

     - a fixed dollar amount per leukocyte.

No minimum order requirement exists under the agreement, however, we have agreed
with them that prior to the date that a New Drug Approval Application becomes
approved by the Food and Drug Administration, we will negotiate in good faith to
reach an agreement on a minimum leukocyte purchase commitment.

     In August 1998, we entered into a fifteen-year agreement with the American
Red Cross for the supply of leukocytes. The American Red Cross collects
approximately half of the U.S. blood supply. The American Red Cross agreement
provides for us to purchase leukocytes, consistent with agreed upon
specifications, based on quarterly forecasts. We may pay for the leukocytes in
cash or our common stock at the option of the American Red Cross, with the
valuation of shares paid determined by the average closing price of our shares
for the five days prior to the payment due date less a discount. The American
Red Cross agreement also contains an initial price per leukocyte modified by a
volume discount pricing schedule and rebate program. This pricing schedule is
subject to periodic renegotiations. Upon execution of the agreement, the
American Red Cross received a warrant to purchase up to 500,000 shares of our
common stock with exercise prices ranging from $5.50 to $11.00 per share. We
also entered into a stockholder's agreement and registration rights agreement
relating to shares underlying the warrant and shares received, if any, in lieu
of cash for leukocyte purchases.

     In August 1998, we entered into a strategic alliance simultaneously with
the purchase of a 10% equity interest in Inflammatics, Inc., a private drug
development company, headquartered in Philadelphia, PA. Inflammatics has focused
on the development of therapeutic drugs for autoimmune disorders. Its lead
product is LeukoVAX, an immunomodulating therapy derived from leukocytes.
LeukoVAX is currently in Food and Drug Administration Phase I/II clinical trials
for rheumatoid arthritis.

     Under the terms of the Inflammatics Agreement, we made an initial
investment by purchasing series A convertible preferred stock of Inflammatics
for $1 million and warrants to purchase 250,000 shares of our common stock
exercisable at prices ranging between $1.00 and $1.78 per share. We also
obtained two options to acquire up to an additional 70% equity position in
Inflammatics through two additional fundings to be made at our option. The first
additional funding, subject to our evaluation of the Phase I/II clinical trial
results, provides for us to issue 1,000,000 shares of common stock, the issuance
of 300,000 common stock purchase warrants exercisable at $1.00 through August
14, 2003, and the underwriting of Phase III clinical trials, in exchange for an
additional 36.3% equity interest. Preliminary estimates of the cost for us to
fund Phase III clinical trials of LeukoVAX range between $6.0 million and $10.0
million. The second additional funding, subject to our further evaluation of the
Phase III clinical trial results, provides for the issuance of an additional
2,000,000 shares of common stock in exchange for an additional 33.3% equity
interest.

                                        22
<PAGE>   26

     In November 1998, Viragen signed an exclusive supply and distribution
agreement with AGC, a Pakistan-based, multinational conglomerate, for the
purchase and distribution of Omniferon. Under this agreement AGC's designated
territories include Saudi Arabia, Kuwait, Yemen, Oman, UAE, Brunei and other
Middle Eastern countries, as well as India and Pakistan. The AGC agreement calls
for AGC to purchase a minimum of $20 million of Omniferon over five years
commencing with AGC's receipt of the required regulatory approvals for product
commercialization in the designated territories and our receipt of the requisite
regulatory approvals to export Omniferon from our commercial manufacturing
facility in Edinburgh, Scotland. The purchase minimums will be secured by a $1
million irrevocable revolving letter of credit. The purchase minimums increase
significantly if and when we obtain regulatory approval for commercialization of
Omniferon in the United States and/or Europe. The AGC agreement has been
approved by the boards of directors of AGC and Viragen.

     Under the terms of the AGC agreement, AGC is responsible for clinical and
regulatory costs to obtain approvals for commercialization of Omniferon in their
designated territories and all subsequent sales, marketing and distribution
activities. The AGC agreement also calls for AGC to build, own and operate, at
their expense, a pharmaceutical distribution facility in a mutually agreeable
location within the designated territories. AGC has informed us that they
initially intend to focus on distribution for hepatitis B and C, diseases which
are at epidemic proportions in the designated territories.

     In July 1999, Viragen entered into a letter of intent with Drogsan
Healthcare, a Turkish pharmaceutical company. The letter of intent outlines the
terms of a supply and distribution agreement between Viragen and Drogsan for
natural interferon, under terms similar to the AGC agreement. The final terms of
this agreement are still being negotiated.

OPERATIONS

     In July 1999, Viragen (Scotland) Ltd. received regulatory approval of its
Clinical Trial Exemption Application, to commence Phase I/II human clinical
trials of its Omniferon product, initially for the treatment of hepatitis C. We
anticipate the commencement of the clinical trials in the fourth calendar
quarter of 1999.

     Viragen initially obtained approval for use of Alpha Leukoferon, its first
generation national interferon product, through approved investigational
protocols in 1983 under Florida Statute 402.36. This statute, the Cancer
Therapeutic Act, was the predecessor to Florida Statute 499. In 1984, Florida
Statute 499.018, was amended to include Viragen's protocols and Florida Statute
402.36 was repealed. In 1986, we received approval from the Florida Health and
Rehabilitation Services under the 499 Program, to distribute Alpha Leukoferon
under

                                        23
<PAGE>   27

specific investigative clinical study protocols through hospitals, pharmacies
and Florida licensed physicians for the treatment of patients within the state
of Florida. We subsequently received state of Florida regulatory approval for
the investigational use of Alpha Leukoferon in the treatment of multiple
sclerosis, HIV/AIDS, AIDS Related Complex, AIDS/Kaposi Sarcoma, 32 types of
cancers, hepatitis and certain other viral diseases. In December 1994, we
discontinued enrollment of new patients in our multiple sclerosis study 499
program.

     In August 1995, we negotiated an agreement with the Florida Department of
Health and Rehabilitative Services which provided for the elimination of the
enrollment of new patients in its existing 499 Program. Following August 1995,
we did distribute on a limited basis for patients approved by the Florida HRS
for humanitarian purposes. In 1996 we distributed Alpha Leukoferon in an
HIV/AIDS study conducted at no charge to patients. We believe the
discontinuation of our participation in the 499 Program will facilitate efforts
in obtaining Food and Drug Administration and European Union approvals for
Omniferon. This is based on management's concern that the continuation of the
499 Program, which involved the ongoing distribution of Alpha Leukoferon and
receipt of limited revenues, was an impediment to obtaining later approvals.

     Viragen will require significant additional financing to conduct and
complete clinical trials for the purpose of obtaining European Union and/or Food
and Drug Administration approvals for Omniferon or LeukoVAX. Clinical testing
toward European Union and/or Food and Drug Administration approval is an
expensive process, which is expected to take several years to accomplish with no
assurance such approvals will eventually be obtained.

THE PRODUCTS

     Viragen derives its Omniferon from human white cells, also known as
leukocytes. Natural interferon is one of the body's natural defensive responses
to foreign substances such as viruses, and is so named because it "interferes"
with viral growth. Natural interferon consists of protein molecules that induce
antiviral, antitumor and immunomodulatory responses within the body. Medical
studies have indicated that interferons may inhibit malignant cell and tumor
growth without affecting normal cell activity.

     There are two basic types of interferon, differentiated primarily by their
method of manufacture and resulting composition. The first, as produced by
Viragen, is a multi-species natural, human leukocyte-derived alpha interferon
produced by cultivated human white blood cells. The introduction of a harmless
agent induces the cells to produce natural interferon. Natural interferon is
then separated from other natural proteins and purified to produce a highly
concentrated product for clinical use. The second type of interferon is
recombinant or synthetic interferon (alpha or beta), which is a genetically
engineered interferon generally produced from a single human gene in bacterial
cells by recombinant DNA techniques.

     Clinical studies suggest that there may be significant therapeutic
differences between the use of natural interferon and synthetic interferon. We
believe that treatment with synthetic interferon in certain cases may cause an
immunological response through the production by the human immune system of
neutralizing and/or binding antibodies, that reduces the effectiveness of the
treatment or which may cause adverse side effects. We believe that the
production of neutralizing and/or binding antibodies is virtually non-existent
in patients treated with natural interferon. Furthermore, primarily due to
biological differences, the side effects of treatment with natural interferon,
in certain instances, may be less severe than with a recombinant or synthetic
interferon.

THE INTERFERON INDUSTRY

     Prior to 1985, natural interferon was the only type of interferon
available. Research institutions and other biomedical companies like Viragen
were working to solve the problem of the high cost related to the
industrial-scale production of natural interferon. In 1985, Hoffman-LaRoche,
Inc. and Schering-Plough Corporation, two major pharmaceutical companies,
successfully developed synthetic interferon using DNA technology and
subsequently received Food and Drug Administration approval to produce and
market their respective recombinant alpha interferon products for the treatment
of hairy-cell leukemia, hepatitis and Kaposi's Sarcoma, an AIDS-related skin
cancer.
                                        24
<PAGE>   28

     After the emergence of recombinant alpha interferon, the medical
community's interest in natural interferon diminished due primarily to the
limited availability and its higher cost of production. Most clinical studies
thereafter utilized a synthetic product.

     Hoffman-LaRoche, Inc. and Schering-Plough Corporation continue to actively
market their products and promote the therapeutic benefits of their respective
synthetic interferon products. In 1993 Chiron Corp. received Food and Drug
Administration approval of BetaSeron(TM), its recombinant beta interferon for
the treatment of relapsing/remitting multiple sclerosis. In 1996, Biogen, Inc.
received Food and Drug Administration approval for Avonex(TM), its recombinant
beta interferon for relapsing/remitting multiple sclerosis. In 1997, Teva
Pharmaceuticals received Food and Drug Administration approval of its peptide
chemical compound, Copaxone(TM), for relapsing/remitting multiple sclerosis. In
addition to the manufacturers of synthetic interferons, a domestic manufacturer
of natural interferon-alpha, Interferon Sciences, Inc., received Food and Drug
Administration approval in 1989 to sell, in injectable form, Alferon(TM), their
natural interferon product for genital warts.

APPLICATIONS OF INTERFERON

     Human leukocyte interferon is a naturally occurring protein which serves to
enhance the body's immune response to certain viral infections. Viragen believes
interferons can arrest the progress of certain viral based infections, reducing
symptoms and disease related complications with a minimum of side effects.

  Hepatitis C

     The hepatitis C virus is a major worldwide cause of acute and chronic
hepatitis. Hepatitis C, previously known as "non-A, non-B hepatitis", affects an
estimated 4 million Americans with approximately 30,000 new cases diagnosed each
year. It is responsible for an estimated 8,000 deaths annually. Hepatitis C is
currently the leading cause of liver transplantation in the United States. Based
on a review of published literature and evaluation by our scientific staff and
advisors, we believe that our Omniferon product may prove effective in the
treatment of this indication.

  Hepatitis B

     Approximately 45% of the world population live in areas with a high
prevalence of hepatitis B infection where the lifetime risk of infection can
exceed 60%. Most infections in these areas are acquired at birth or during early
childhood when the risk of developing chronic infection is highest. In the
United States, which is not in a high prevalence area, approximately 300,000
cases of acute hepatitis B are diagnosed annually with 2% to 10% of these
patients developing chronic infections. These infections put the patients at
risk of progressive liver disease possibly leading to cirrhosis and/or
hepatocellar carcinoma.

     Synthetic interferon alpha is the only Food and Drug Administration
approved drug for hepatitis B and has been found to be an effective treatment in
some cases. Viragen believes that Omniferon may also prove effective in the
treatment of hepatitis B.

  Multiple Sclerosis

     In 1988, following State of Florida regulatory approval for use of
Viragen's Alpha Leukoferon product for the treatment of multiple sclerosis, we
entered into a research agreement with the University of Miami School of
Medicine, Department of Neurology, Multiple Sclerosis Center. Under the Florida
499 Program, we conducted a patient funded, multi-phase clinical trial for the
treatment of multiple sclerosis with Alpha Leukoferon. This study was conducted
on a double-blind basis with certain patients receiving different dosage levels
of that product and certain patients receiving a placebo. The study terminated
in mid-1992. Published information on these trials indicated that, in many
cases, our Alpha Leukoferon product provided favorable results in the treatment
of patients afflicted with relapsing/remitting, relapsing progressive and
chronic progressive multiple sclerosis.

                                        25
<PAGE>   29

     The principal investigator for this study authored, together with other
investigators, an abstract of the favorable results achieved in many cases with
the use of our Alpha Leukoferon product in the treatment of various types of
multiple sclerosis. The abstract titled "Stabilization of Relapsing-Remitting
and Progressive Multiple Sclerosis with Natural Interferon Alpha: A Preliminary
Trial," was published in the Annals of Neurology, the official journal of the
American Neurological Association in 1994. An additional article was published
by the investigators and Viragen titled "Natural Alpha Interferon in Multiple
Sclerosis: Results of Three Preliminary Series," appeared in the Journal of
International Medical Research in 1996.

  Chronic Myelogenous Leukemia

     Chronic myelogenous leukemia is one of a group of diseases called
myeloproliferative disorders and is usually recognized by a distinctive
cytogenetic abnormality, known as the Philadelphia chromosome. The current
treatment for chronic myelogenous leukemia is high dose chemotherapy with bone
marrow transplantation. Interferon therapy has emerged as a possible effective
initial treatment in this disease affecting both the presence of leukemia cells
as well as the number of bone marrow cells having the Philadelphia chromosome.

  HIV/AIDS

     In July 1990, Viragen received approval from the Florida Health and
Rehabilitative Services for an HIV/AIDS treatment protocol using Alpha
Leukoferon in injectable form. In September 1993, we began distribution on a
limited basis of our product under this protocol. However, in December 1994,
Health and Rehabilitative Services informed us that no new patients may be
enrolled under the 499 Program, including those patients with HIV/ AIDS, ARC and
Kaposi's Sarcoma, until we had satisfied them of our compliance with Food and
Drug Administration promulgated current Good Manufacturing Practice
requirements. In July 1995, we discontinued enrollment of new patients in its
499 Program and in August 1995, reached a settlement agreement with the Florida
Health and Rehabilitative Services which provided for the elimination of the
enrollment of new patients in the 499 Program, with the possible exception of
certain limited enrollments approved by the Florida Health and Rehabilitative
Services for humanitarian purposes, the continued participation by previously
enrolled patients in the 499 Program and the resolution of other issues.

     In March 1996, Viragen in collaboration with Biodoron, a Hollywood, Florida
based clinic, received approval from Health and Rehabilitative Services under
Florida's Investigational Drug Program to conduct an investigational study in
Florida of our Alpha Leukoferon product, for the treatment of HIV/AIDS in
hemophiliacs. Viragen entered into an agreement with Quantum Health Resources,
Inc., which contributed $330,000 toward to the cost of the study. Quantum, a
subsidiary of Olsten Services Corp., is a national provider of alternate site
therapies and support services for people affected by chronic disorders,
including hemophilia. The study commenced in March 1996, and 35 patients
enrolled to receive Alpha Leukoferon for a minimum of six months in combination
with a comprehensive HIV/AIDS treatment program. While the study suggested that
Alpha Leukoferon was safe or well tolerated, the overall study results proved to
be inconclusive due to the smaller than anticipated number of patients that
finished the study.

MANUFACTURE OF INTERFERON

     Human white blood cells, also known as leukocytes, and a stimulating agent,
raw materials which are readily available to us, are needed to produce human
interferon. A Food and Drug Administration approved stimulating agent, which is
harmless to humans, is introduced into the white blood cell, which induces the
cell to produce interferon. The interferon is then separated from other
proteins, extracted and purified.

     Viragen's Omniferon product is currently being manufactured in its Scottish
facility for use in planned human clinical trials anticipated to commence in the
fourth quarter of calendar 1999. Our first generation of natural interferon was
manufactured and distributed in Florida under the 499 Program under the name
Alpha Leukoferon. Production of Alpha Leukoferon was discontinued in January
1995.

     Production methods that we have developed, as well as enhanced methods
currently under development could serve to reduce our costs of production and,
ultimately, the market price of Omniferon to patients.

                                        26
<PAGE>   30

However, there can be no assurance that this new manufacturing technology will
enable us to achieve the level of manufacturing proficiency and product
improvement hoped for.

RESEARCH AND DEVELOPMENT

     The entire process of research, development and European Union and/or Food
and Drug Administration approvals, if obtained, of a new bio-pharmaceutical
takes several years and requires substantial funding. In July 1999, Viragen
received approval of its European Clinical Trial Exemption Application to
commence clinical trials of Omniferon and, through its equity investment in
Inflammatics, is currently engaged in Food and Drug Administration Phase I/II
clinical trials of LeukoVAX. The completion of clinical studies for either
product which is required prior to obtaining marketing approval, is dependent
upon obtaining significant additional funding. Our present focus is the
continued research and development of Omniferon for the treatment of hepatitis B
and C, multiple sclerosis, chronic myelogenous leukemia, herpes and HIV/AIDS.

     We have spent a substantial amount of time and resources on the research
and development of improved cell stimulation and purification techniques for our
Omniferon product. We believe that the improvement of these processes will
enhance the purity of the product while increasing production yields. We believe
that research efforts focused on increased production yields, if successful,
would significantly lower related costs of production, ultimately allowing a
lower more competitive sales price of Omniferon.

     Research and development costs totaled $5,152,748, $4,222,332 and
$2,360,416, for fiscal years ended June 30, 1999, 1998 and 1997, respectively.

ROYALTY AGREEMENT

     Viragen and Medicore, Inc., a former affiliate, have a royalty agreement
that provides for a maximum cap on royalties to be paid to Medicore of
$2,400,000, with a schedule of royalty payments of: 5% of the first $7,000,000
of sales of interferon and related products, 4% of the next $10,000,000 of sales
and 3% of the next $55,000,000 of sales until the total of $2,400,000 royalty is
paid. The agreement also specified that royalties of approximately $108,000
previously accrued as payable to Medicore will be the final payment due under
the agreement. As we have had no interferon sales, no royalty expense has been
recognized for the three fiscal years ended June 30, 1999.

PATENTS

     Viragen believes its production techniques are unique and are capable of
yielding a superior quality product. We believe that our production techniques
will allow us to offer Omniferon at a price competitive with the recombinant
interferons currently being marketed.

     Viragen has filed two patent applications covering Omniferon production
techniques. We have also submitted several foreign patent applications relating
to natural interferon for topical use, several of which have been granted.
During fiscal 1999, our patent issued in Japan for the topical use of interferon
was challenged by a Japanese company. We defended our patent position and were
successful in our defense.

     Under a license agreement between Viragen and its majority owned
subsidiary, Viragen (Europe) Ltd. dated July 12, 1995, Viragen (Europe) was
granted exclusive rights to Viragen's proprietary technologies, including those
technologies covered by patent, for all countries comprising the European Union.
In addition, this agreement granted Viragen (Europe) the non-exclusive rights to
Viragen's technology throughout the world, excluding the United States and its
territories. This agreement provides that Viragen (Europe) will pay Viragen a
royalty ranging from 10% to 5% of sales, with a minimum of $2 million per year,
subsequently modified to $167,000 per month. The minimum royalty payment has
been deferred by Viragen until such time as Viragen (Europe) has the necessary
cash flow to meet this payment. This agreement has an initial term of 15 years
and automatically renews for two successive 15-year periods.

     United States patents have been issued to others with respect to
genetically engineered and human-derived interferon. Subject to the extent of
such existing patent claims, Viragen may have to negotiate license agreements
with such patent holders to use such processes and products. We believe that we
do not infringe upon any current patent.

                                        27

<PAGE>   31

     The validity and enforceability of a patent can be challenged by litigation
after its issuance. If the outcome of that litigation is against the owner of
the patent, other parties may be free to use the subject matter covered by the
patent. The degree of protection afforded by foreign patents may be different
than in the United States. We cannot assure you that patents obtained in the
future will be of substantial protection or commercial benefit to us.

REGULATION

  United States and European Union

     Viragen's activities and its products and processes resulting from such
activities are subject to substantial government regulation in the United States
at both state and federal levels and within the European Union member nations.
The manufacturing, advertising and sale of biologic substances and
pharmaceutical products are regulated by, and require the approval of, the
European Union, Food and Drug Administration, state and local agencies. We
followed strict production and distribution procedures under state of Florida
Health and Rehabilitative Services guidelines relating to our limited
distribution of our Alpha Leukoferon within the state of Florida. The Food and
Drug Administration has established mandatory procedures and standards which
apply to the clinical testing, marketing and manufacture of any biologic product
including ours. Obtaining European Union and/or Food and Drug Administration
approval for commercialization of any new product can take significant time and
capital since it involves extensive testing procedures and lengthy clinical
trials. These trials involve the measurement of product safety, toxicity, and
efficacy, if any, under specific protocols. The process of obtaining European
Union and/or Food and Drug Administration regulatory approval extensive animal
testing to demonstrate product safety and preferred dosages. Human tests are
then performed to show and to document findings as to safety, effectiveness,
toxicity and side effects. Biostatistical analysis of data is then gathered and
evaluated, followed by the submission of all information and data to the
regulatory authorities.

     Viragen, through Viragen (Scotland), has completed the preclinical studies
of its Omniferon product in the European Union, and in July 1999 received
approval of its Clinical Trial Exemption application to commence clinical trials
on humans. We intend to commence clinical trials in the European Union during
the fourth calendar quarter of 1999 and eventually submit an Investigative New
Drug Application to the Food and Drug Administration for use of Omniferon in the
U.S. To help us during the approval process, we have assembled a clinical
advisory committee consisting of scientists, medical researchers and clinicians
who are acting in an advisory capacity in order to assist us in developing the
medical, scientific and clinical aspects in support of our clinical trials
initially with the European Union and eventually in the United States.

     In Europe and the United States, human clinical trial programs generally
involve a three phase process. Typically, Phase I trials are conducted in
healthy volunteers to determine the early side effect profile and the pattern of
drug distribution and metabolism. Phase II trials are conducted in groups of
patients afflicted with the target disease to provide sufficient data for the
statistical proof of efficacy and safety required by regulatory agencies. If
Phase II evaluations indicate a product demonstrated potential effectiveness and
has an acceptable safety profile, Phase III trials are performed to conclusively
demonstrate clinical efficacy and safety within an expanded patient population
from multiple clinical study sites. Regulatory authorities may also require
Phase IV studies to track patients after a product is approved for commercial
sale.

     Regulatory approvals of a new pharmaceutical or biopharmaceutical product
can often take five years or longer unless accelerated in certain instances for
life-threatening diseases. In all cases this process involves the use and
expenditure of substantial resources. Approval depends on a number of factors,
including the severity of the disease in question, the availability of
alternative treatments and the risks and benefits demonstrated in clinical
trials.

     American pharmaceutical manufacturers who sell outside of the United States
are also subject to Food and Drug Administration jurisdiction. Semi-finished
drugs may be shipped under certain controlled circumstances for further
processing, packaging, labeling and distribution to third parties residing in
approved foreign countries, subject to the laws that apply in those countries.
For Viragen to conduct this type of sale, we must comply with all Food and Drug
Administration rules and regulations as well as those of the country to which

                                        28
<PAGE>   32

we intend to ship the product before we would be permitted to export crude or
finished interferon products outside the United States.

  License and Manufacturing Agreement

     In certain instances, European Union regulations may require less stringent
preclinical studies for naturally occurring substances such as our Omniferon
product than for genetically engineered products. Accordingly, while there can
be no assurance, we expect to possibly receive an accelerated review of the
various European Union processes and clinical trials prior to market approval in
the European Union.

     In July 1995, Viragen (Scotland) entered into a license and manufacturing
agreement with the Common Services Agency of Scotland to secure a sufficient
source of needed raw materials as well as expertise in the area of blood-derived
products and the regulatory approval process. The agency is an adjunct of the
Scottish Government which acts on behalf of the National Health Service in
Scotland and the Scottish National Blood Transfusion Service. The agency owns
and operates a blood fractionation facility in Edinburgh, Scotland, and has the
physical and technical capacity to supply leukocytes and manufacture alpha
interferon from human leukocytes using our processes. We believe that securing a
sufficient qualified long-term source of blood-derived raw materials within the
European Union is critical to enable us to conduct European Union clinical
trials as well as providing a sufficient source of raw materials necessary for
subsequent commercial manufacturing.

     During fiscal 1998, we were notified that, due to concerns over the
possible presence of New Varient Creutzfeld-Jacob disease, also known as Mad Cow
disease, in the UK blood supply, human leukocytes collected in Scotland,
including those intended to be supplied under the Scottish agreement, would not
be approved for use in our planned clinical trials or potential commercial
production until the European regulatory authorities were satisfied that the
risk of contamination had been minimized. Due to their situation, we intend to
use leukocytes collected in Germany under our German Red Cross contractual
arrangements as well as other approved sources to continue with our planned
clinical trials and possibly the commencement of commercial scale production if
needed.

     Under the terms of the agreement with the German Red Cross, our subsidiary,
Viragen (Germany) GmbH, has the right to receive on a preferential basis
leukocytes produced by the German Red Cross in Germany. Viragen (Germany) has a
right to receive on such a preferential basis 1,000,000 leukocytes per year with
deliveries to be ordered on a quarterly basis. During the initial two-year
period of the agreement, Viragen (Germany) may determine its annual order
quantity up to 1,000,000 leukocytes. After the initial two-year period, the
annual order quantity will be 1,000,000 leukocytes plus or minus 15%. Under this
agreement we will pay the German Red Cross on a percentage of sales of Omniferon
attributable to Viragen (Germany) leukocytes. The German Red Cross will also be
entitled to receive priority distributions of Omniferon from German sourced
leukocytes. Leukocytes provided by the German Red Cross have been approved for
use in our Scottish facility. Processing to separate the leukocytes from German
whole blood donations will be done in Germany at the facilities of the German
Red Cross.

     Prior to the beginning of clinical trials, our Scottish manufacturing
facility must be approved by European Union regulatory authorities. We engaged
professionally recognized consultants familiar with the European Union
regulatory process to assist in the manufacturing and product approval
submissions to the European Union regulatory authorities. In addition, the
Scottish Blood Transfusion Service has a full-time regulatory department that
has obtained approval in the European Union of numerous European Union
blood-derived products. The Scottish Blood Transfusion Service will also work
with us to obtain a manufacturing license and subsequent product approvals at
the conclusion of the European Union clinical studies. After a manufacturing
license is obtained for Omniferon, we intend to seek Food and Drug
Administration manufacturing approval of our Scottish manufacturing facility.
However, we can give you no assurances that the Food and Drug Administration
will license or approve the Scottish manufacturing facility or Omniferon for
clinical trials and subsequent distribution in the United States.

     Viragen (Scotland) was organized to manufacture and distribute Omniferon
and related products in the European Union and other countries outside the
United States. Viragen has transferred patent and proprietary

                                       29
<PAGE>   33

rights associated with the production of Omniferon and related technology to
Viragen (Scotland) under a grant of license. Viragen (Scotland) has provided the
Transfusion Service with an exclusive license to use the proprietary rights
covered by the license and manufacturing agreement for the manufacture and
distribution of Omniferon within the European Union. The Transfusion Service has
committed to participate with us in the manufacture of Omniferon in sufficient
scale to accommodate the European Union clinical trials and also to conduct
studies relevant to our product and cooperate with us in complying with the laws
and regulations of the European Union in connection with the production of
Omniferon.

     Under the terms of the license and manufacturing agreement, we are
providing the Transfusion Service with full access to our proprietary technology
and specialized equipment. We are also absorbing all costs associated with
securing permits and regulatory approvals, augmenting the Transfusion Service
facilities, if necessary, to participate in the manufacture of Omniferon and
securing documentation demonstrating compliance with European Union regulatory
requirements.

     We have agreed to pay the Transfusion Service for product manufactured for
use in clinical trials in the European Union, for product manufactured for sales
prior to obtaining new drug application approval, and for sales following such
approval. Under this arrangement, payments will be made at varying percentages
in relation to costs. For products manufactured for use in clinical trials, they
are entitled to cost plus 25%, for sales prior to obtaining new drug
application approval, cost plus 40%, and for sales following approval, cost plus
50%. Products manufactured and used for humanitarian purposes or for medical use
by patients of the Scottish National Health Services or the United Kingdom
National Health Services will involve either no payments to the agency or
payments at substantially discounted prices. We also have agreed to pay the
Transfusion Service for providing process documentation for any additional
manufacturing facilities we might establish.

     The term of the license and manufacturing agreement is for a five-year
period with two additional five-year extension terms at our option. The
agreement also contains provisions protecting our proprietary rights and limits
of certain competitive activities by the Transfusion Service.

COMPETITION

     Competition in the research, development and production of interferon, and
other immunological products is intense and involves major, well-established and
abundantly financed pharmaceutical and commercial entities, as well as major
educational and scientific institutions. Many researchers, some of whom have
substantial private and government funding, are involved with interferon
production, including production of interferon through recombinant DNA
technology. A number of large companies including Hoffman-LaRoche, Inc.,
Schering-Plough Corporation, Glaxo-Wellcome, Biogen, Inc., Chiron Corp., Berlex
Laboratories and Ares-Serono are producing, selling and conducting clinical
trials with recombinant interferons (alpha and beta) and other immunological
products for the treatment of certain cancers and viral infections, including
hepatitis C, our first targeted use of Omniferon.

     In addition to the manufacturers of synthetic interferons, Interferon
Sciences, Inc., a domestic manufacturer of natural interferon, received Food and
Drug Administration approval in 1989 to sell, in injectable form, their natural
interferon product for genital warts.

     We believe that competition is also based on production ability,
technological superiority and administrative and regulatory expertise in
obtaining governmental approvals for testing, manufacturing and marketing of the
product.

     The timing of the entry of a new pharmaceutical product into the market is
an important factor in determining that product's eventual success. Early
marketing has advantages in gaining product acceptance and market share. Our
ability to develop products, complete clinical studies and obtain governmental
approvals in the past had been hampered by a lack of adequate capital. Viragen
is not presently a competitive factor in revenue participation in the
biopharmaceutical industry.

EMPLOYEES

     As of September 10, 1999, we have 41 employees, of which 30 are research
and development and quality assurance/quality control personnel. The remaining
11 employees are management, regulatory and/or administrative personnel.

PROPERTIES

     In November 1996, Viragen entered into a ten year lease for 14,800 square
feet in Plantation, Florida. This location contains our domestic administrative
and executive offices. The lease contains an option for up to two additional
five-year terms. Base lease payments on the facility total $15,700 per month.
Our administrative offices are located at 865 SW. 78th Avenue, Suite 100,
Plantation, Florida 33324; phone (954) 233-8746.

     Viragen owns a 14,000 square foot building in Hialeah, Florida. This
facility includes a laboratory for biomedical research and development
activities. In August 1999, we obtained a $600,000 mortgage on our Florida
laboratory facility. The mortgage provides for payments of interest only, at the
prime rate plus 1%, through July 2000, at which time the principal is payable in
full. We intend to sell our Florida laboratory facility during fiscal 2000,
consolidating our research and production assets in our Edinburgh, Scotland
facility.

     In November 1996, through Viragen (Scotland), we entered into a five year
lease agreement in a biotechnology park in the Edinburgh area of Scotland. This
facility, consisting of approximately 12,000 sq. ft., contains our European
laboratory and production facilities. This location augments other productive
assets available to us within the Transfusion Service facility under the
Scottish agreement. The annual base lease rate for the facility is 71,700 UK
pounds or approximately US$119,700 plus adjustment for common area maintenance
charges. Viragen (Scotland) has the right to renew the lease for four additional
five-year terms.

     We believe our properties are in good condition, well-maintained and
generally suitable and adequate to carry on our business. We also believe that
we maintain sufficient insurance coverage on all of our real and personal
property.

LEGAL PROCEEDINGS

     In October 1997, Viragen, the company's president and Cytoferon Corp., a
former affiliate of the president, were named as defendants in a civil action
brought in the United States District Court for the Southern District of Florida
(Walter L Smith v Cytoferon Corp. et al; Case No: 97-3187-CIV-MARCUS) by a
Viragen stockholder and investor in Cytoferon Corp. The suit alleged the
defendants violated federal and state securities laws, federal and state RICO
statutes, fraud, conspiracy, breach of fiduciary duties and breach of contract.
The plaintiff was seeking an unspecified monetary judgement and the delivery of
441,368 shares of common stock. Viragen filed a motion to dismiss denying the
allegations and requesting reimbursement of its costs.

     In November 1997, the plaintiff in this litigation filed a notice of
voluntary dismissal with the federal court concurrently notifying Viragen of his
intent to refile a complaint in circuit court in the state of Florida.

     In December 1998, the U.S. District court awarded us reimbursement of
attorneys' fees and expenses under Rule 11 of the Federal Rules of Civil
Procedure and the Private Securities Litigation Reform Act. While there can be
no assurance as to the amount, if any, that we will ultimately recover, we have
submitted to the Court a request for reimbursement of litigation related costs
of approximately $75,000.

     The plaintiff filed a complaint in the Circuit Court of the 11th Judicial
Circuit for Miami-Dade County, Florida (Case No: 97-25587 CA30) naming the same
defendants. The suit alleges breach of contract, fraud, violation of Florida's
RICO statute and breach of fiduciary duties and seeks an unspecified monetary
judgment and specific performance delivery of 441,368 shares of common stock.
The plaintiff is claiming that he is entitled to additional shares of common
stock under a consulting agreement, that Viragen's President breached his
fiduciary duty to Cytoferon Corp. by not achieving sufficient financing for
Viragen which would

                                       31
<PAGE>   35

have entitled Cytoferon Corp. to additional shares and for misrepresentations in
connection with the previous Cytoferon financings.

     In March 1998 the Circuit Court granted Viragen's Motion to Dismiss the
complaint. Subsequently, the plaintiff filed an Amended Complaint alleging
breach of contract, fraud, violation of Florida's RICO ACT and breach of
fiduciary duties and seeking an unspecified monetary judgement and specific
performance delivery of 441,368 shares of common stock. In April 1998, Viragen
filed a Motion to Dismiss plaintiff's amended complaint which was denied by the
Court. Viragen denies the allegations of the complaint and intends to continue
to vigorously defend the claims with regard to this matter. The ultimate
liability, if any, resulting from this litigation cannot be determined at this
time and no accrual for loss has been recorded.

     On February 28, 1997, we amended our Certificate of Incorporation and
established a classified board of directors commencing with the 1997 annual
meeting. Following that meeting, directors were divided into three subclasses
consisting of class A, class B and class C, respectively. The initial term of
the class A directors expired after the 1998 annual meeting of stockholders; the
term of the class B directors initially expires after the 1999 annual meeting of
stockholders; and the term of the class C directors initially expires



















                                       33
<PAGE>   37

after the 2000 annual meeting of stockholders. At each annual meeting of
stockholders, directors of the respective class whose term expired will be
elected. Directors chosen to succeed those whose terms have expired will be
elected to hold office for a term to expire at the third ensueing annual meeting
of stockholders after their election, and until their respective successors are
elected and qualified.

compensation committee also communicate with Viragen's independent certified
public accountants, on behalf of the board of directors. This committee also
receives written reports, supplemented by such oral reports as it deems
necessary, from the audit firm. The audit, finance and compensation committee
also provides overall guidance for officer compensation programs, including
salaries and other forms of compensation, and for implementation of Viragen's
budget process. Prior to fiscal 1998, our board of directors acted as a whole as

1997 AMENDED STOCK OPTION PLAN AND 1995 AMENDED STOCK OPTION PLAN

     On May 15, 1995 the board of directors adopted, subject to approval by the
stockholders, a stock option plan, called the 1995 stock option plan. On
September 22, 1995, the board of directors amended the 1995 stock option plan to
define certain terms and clarify the minimum exercise price of the non-qualified
options to as not less than 55% of the fair market value. The 1995 stock option
plan was submitted to the stockholders at the annual meeting of stockholders
held on December 15, 1995, and the stockholders ratified the plan at that time.

     On January 27, 1997 the board of directors adopted, subject to approval by
the stockholders, a stock option plan called the 1997 stock option plan,
containing terms and provisions similar to the 1995 stock option plan. The 1997
stock option plan was submitted to the stockholders for approval at the annual
meeting of stockholders held on February 28, 1997 at which time the plan was
ratified. On April 24, 1998 the board of directors adopted, subject to
ratification by the stockholders, an amendment to the 1997 stock option plan,
reserving an additional 1,000,000 shares of common stock for issuance under that
plan. This amendment brought the total shares reserved under the 1997 stock
option plan to 4,000,000 shares. On July 31, 1998, the stockholders ratified
this amendment to the 1997 stock option plan.

     Under both the 1995 stock option plan and the 1997 stock option plan,
Viragen has reserved of common stock for issuance. The audit, finance and
compensation committee of the board of directors and the board of directors
currently administer the plans including, the selection of the persons who will
be granted plan options under the plans, the type of plan options to be granted,
the number of shares subject to each plan options and the plan options price.

     Plan options granted under either the 1995 stock option plan or the 1997
stock option plan may either be options qualifying as incentive stock options
under Section 422 of the Internal Revenue Code of 1986, as amended, or options
that do not so qualify. In addition, the plans also allow for the inclusion of a
reload option provision, which permits an eligible person to pay the exercise
price of the plan option with shares of common stock owned by the eligible
person and receive a new plan option to purchase shares of common stock equal in
number to the tendered shares. Any incentive option granted under the plan must
provide for an exercise price of not less than 100% of the fair market value of
the underlying shares on the date of such grant. The exercise price of any
incentive option granted to an eligible employee owning more than 10% of our
common stock must be at least 110% of such fair market value as determined on
the date of the grant. The term of each plan option and the manner in which it
may be exercised is determined by the board of directors or the audit, finance
and compensation committee. No plan option may be exercisable more than 10 years
after the date of its grant and, in the case of an incentive option granted to
an eligible employee owning more than 10% of Viragen's common stock, no more
than five years after the date of the grant.

     The exercise price of non-qualified options will be determined by the board
of directors or the audit, finance and compensation committee.

     The per share purchase price of shares subject to plan options granted
under the plans may be adjusted in the event of certain changes in Viragen's
capitalization, but any adjustment cannot change the total purchase price
payable upon the exercise in full of plan options granted under the plans.

                                       39
<PAGE>   43

     Officers, directors, key employees and consultants of Viragen and its
subsidiaries are eligible to receive non-qualified options under the stock
option plans. Only officers, directors and employees who are employed by Viragen
or by any of its subsidiaries are eligible to receive incentive options.

     Incentive options are nonassignable and nontransferable, except by will or
by the laws of descent and distribution, and during the lifetime of the
optionee. Incentive options may be exercised only by the optionee. Under a
recent amendment to the 1997 stock option plan, non-qualified options may be
transferable under limited circumstances for estate planning if authorized by
the board of directors or the committee. If an optionee's employment is
terminated for any reason, other than his death or disability or termination for
cause, or if an optionee is not an employee but is a member of Viragen's board
of directors and his service as a director is terminated for any reason, other
then death or disability, the plan option granted to him will lapse to the
extent unexercised on the earlier of the expiration date or 30 days following
the date of termination unless otherwise extended by the board. If the optionee
dies during the term of his employment, the plan option granted to him shall
lapse to the extent unexercised on the earlier of the expiration date of the
plan option or the date one year following the date of the optionee's death. If
the optionee is permanently and totally disabled within the meaning of Section
22(c)(3) of the Internal Revenue Code of 1986, the plan option granted to him
lapses to the extent unexercised on the earlier of the expiration date of the
option or one year following the date of such disability.

     The board of directors or the audit, finance and compensation committee may
amend, suspend or terminate the plans at any time, except that no amendment can
be made which (1) changes the minimum purchase price, except in either case in
the event of adjustments due to changes in Viragen's capitalization, (2)
affects outstanding plan options or any exercise right, (3) extends the term of
any plan option beyond ten years, or (4) extends the termination date of the
plans. Unless the plans have been suspended or terminated by the board of
directors, the 1995 stock option plan will terminate on May 15, 2005 and the
1997 stock option plan will terminate on January 27, 2007. The termination of
either plan will not affect the validity of any plan options previously granted.

     As of September 24, 1999, 3,965,000 options have been issued and are
outstanding under the 1995 stock option plan and 3,574,000 options have
been issued and are outstanding under the 1997 stock option plan.

                              CERTAIN TRANSACTIONS

     Gerald Smith and Dennis W. Healey, who are principal executive officers of
Viragen, also serve as the principal executive officers of Viragen (Europe).
Messrs. Smith and Healey and also serve as principal executive officers of our
majority-owned subsidiary, Viragen U.S.A., Inc. Commencing in July 1996,
following his resignation from Medicore and subsidiaries, Mr. Healey who is
serving as Viragen (Europe's) executive vice president, treasurer and secretary,
began receiving an annual salary of $85,000 per year from that company. On
March 1, 1997, Messrs. Smith and Healey entered into two year employment
agreements, subsequently amended, with Viragen (Europe) under terms similar to
their employment agreements. The agreements provide for annual salaries of
$72,000 and $52,000, respectively.

     On April 25, 1997, Viragen loaned William Saeger, a former director,
$100,000, receiving a one year promissory note bearing interest at 8 1/2%. In
April 1998, Mr. Saeger defaulted on this note. Due to a subsequent deterioration
in Mr. Saeger's health and financial condition, we were unable to ascertain the
amounts, if any, which could ultimately be realized on the promissory note.
Accordingly, the entire amount due under the note with related accrued interest
of approximately $10,000 was written-off as uncollectable by fiscal 1998 year
end. We intend to pursue collection efforts relative to this transaction.

     On September 1, 1998, Gerald Smith and Dennis W. Healey each exercised
250,000 options to purchase common stock. The options were exercised through the
issuance of promissory notes payable to Viragen totaling $300,000. Messrs. Smith
and Healey also entered into related pledge and escrow agreements. The
promissory notes bear interest at 5.47%, payable semi-annually and are secured
by the underlying common stock purchased. The purchased shares are being held in
escrow pending payment of the related notes pursuant to the provisions of the
pledge and escrow agreements.

     Options were also exercised by Mr. Carl Singer, a director, for 50,000
shares on October 1, 1998, Mr. Peter Fischbein, a director, for 200,000 shares
on October 8, 1998 and Mr. Charles F. Fistel a former officer, for 410,000
shares on May 3, 1999 (300,000 shares) and May 11, 1999 (110,000 shares). These
options were exercised through the issuance of promissory notes payable Viragen
totaling $302,000, and related pledge and escrow agreements. The promissory
notes bear interest at rates ranging between 5.06% and 5.15%, payable semi-
annually and are secured by the underlying common stock purchased. The purchased
shares are being held in escrow pending payment of the related notes pursuant to
the provisions of the pledge and escrow agreements.

     During fiscal 1999, Viragen issued 1,339,000 options to purchase common
stock to consultants (1,245,000 shares) and employees (94,000 shares).

     On July 1, 1999, in connection with his two year employment agreement, Dr.
D. Magnus Nicolson received a grant of 200,000 options to purchase common stock
of Viragen with an exercise price of $0.625 per share. The options are
exercisable for a period of five years from vesting and vest one-half on the
first anniversary of the grant date and one-half on the second anniversary.

     On April 27, 1998, Viragen U.S.A. Inc., entered into a two year employment
agreement with Mr. Melvin Rothberg to serve as its chief executive officer. The
employment agreement provided for an annual salary of $150,000 and options to
purchase 125,000 shares of Viragen U.S.A. common stock, exercisable at $.22 per
share, vesting 50,000 shares and 75,000 shares on the first and second
anniversaries, respectively. This stock option agreement also provided that if
Viragen U.S.A. did not complete an initial public offering of its stock within
two years of the effective date of the employment agreement, Viragen and Mr.
Rothberg will negotiate an exchange of his Viragen U.S.A. options into options
of Viragen or a publicly traded subsidiary with equal value to Mr. Rothberg's
Viragen U.S.A. options.

     During fiscal 1998, Viragen issued 449,500 options to purchase common stock

(50,000), and former directors; Jay Haft (50,000), William B. Saeger (50,000),
Fred D. Hirt (50,000) and Charles F. Fistel (50,000). In addition, between
August 1996 and June 1997, Viragen awarded options to purchase up to 459,500
shares of common stock to other employees (inclusive of 250,000 of Charles F.
Fistel), which options are exercisable at prices ranging from $1.97 to $3.69 per
share during the five year term of the options.

BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Exchange Act requires our directors and executive
officers, and persons who own more than ten percent (10%) of a registered class
of our equity securities, to file with the Securities and Exchange Commission
initial reports of their ownership and reports of changes in their ownership of
common stock and other equity securities of Viragen. Officers, directors and
greater than ten percent (10%) stockholders are required by regulation to
furnish us with copies of all Section 16(a) forms they file.

     To our knowledge, based solely on a review of the copies of these reports
furnished to us and written representations that no other reports were required,
during the fiscal year ended June 30, 1999, all Section 16(a) filing
requirements applicable to our officers, directors and greater than ten percent
(10%) beneficial owners were completed and timely filed.

                            SELLING SECURITY HOLDERS

TRANSACTION OVERVIEW

         On March 17, 1999, we entered into a purchase agreement with the
Isosceles Fund Limited and Cefeo Investments Limited. We signed an amended
agreement to the purchase agreement on June 16, 1999. This amendment reduced the
conversion price, waived first refusal rights for an interim financing and
extended the date for Viragen to complete the processing of its registration
statement. The purchase agreement:

         o    describes the terms pursuant to which we issued Isosceles and
              Cefeo 8% redeemable promissory notes in the aggregate principal
              amount of $2,000,000 and warrants to purchase shares of our common
              stock;

         o    requires us to indemnify Isosceles, Cefeo and their respective
              officers, directors and affiliates from any damages they incur if
              we breach the purchase agreement; and

         o    gives Isosceles a right of first refusal to participate in private
              equity financings we undertake prior to March 17, 2000.

         At the same time we executed the purchase agreement, we entered into a
memorandum of agreement with Isosceles which gave us the option to sell
Isosceles an aggregate of up to $7,000,000 of additional notes and warrants in
two tranches. Neither Viragen nor the selling security holders have an
obligation to complete the subsequent tranches.

         NOTES. We issued Isosceles and Cefeo promissory notes in the principal
amount of $2,000,000 under the purchase agreement. The principal amount of the
notes accrued interest at a rate of 8% annually.




                                       44

<PAGE>   48

         CONVERSION. One-half of the principal balance and accrued interest on
the related principal converted automatically into 2,049,534 shares of our
common stock on July 7, 1999. In addition, the remaining one-half of the
principal balance and accrued interest on the notes converted automatically into
2,062,685 shares of our common stock on August 6, 1999. The conversion price was
$0.50 per common share

         In addition to the shares issued on conversion of the notes, the note
holders were entitled to receive additional shares of our common stock 30 days
after each one-half of the notes converted into shares of our common stock, as
required by a re-set provision. The purpose of this arrangement was to make sure
that the selling security holders had a return of at least 20% on the shares
received on the conversion of the first half of the notes and at least 22%
return on the conversion on the remaining half of the notes.

         The number of additional shares to which the note holders were entitled
was calculated by dividing $0.644 by the lowest closing bid price of our common
stock during the ten consecutive trading days preceding each re-set date. The
quotient obtained was multiplied by 1.2 on the first re-set date and 1.22 on the
second re-set date. The resulting product was reduced by 1. The resulting number
was then multiplied by the shares issued on the first or second conversion
dates, as appropriate. The formula is as follows:

          (applicable rate X $0.644/future price) -1) x (shares issued)

         On August 6, 1999, Isosceles and Cefeo received a total of 546,990
additional common shares, based on the first re-set calculation. These shares
were issued using a future price of $0.61 per share. On September 5, 1999,
Isosceles and Cefeo received a total of 551,203 additional common shares, based
on the second re-set calculation. These shares were issued using a future price
of $0.62 per share.

         DEFAULT. The purchase agreement, notes and registration rights
agreement defined several events of default including:

         o    failure to continue trading on the NASDAQ stock market;

         o    failure to have this registration statement effective by
              July 7, 1999, the initial deadline;

         o    failure to have this registration statement effective by
              September 13, 1999, the final deadline;

         o    failure to maintain this registration as effective for 30
              consecutive days.

         As Viragen was delisted from the NASDAQ Stock Market on June 28, 1999,
and has failed to meet the two registration deadline requirements, we are in
default of these terms. Accordingly, we continue to accrue a penalty of $40,000
per month. Also, Isosceles and Cefeo holders have the right to request a cash
redemption of the common shares issued upon conversion of the notes. The
redemption, if requested, would require us to pay the $2 million note principal
plus a premium of 25% and related interest and penalties. To date, the selling
security holders have not requested a cash redemption.

                                       45

<PAGE>   49

THE WARRANTS

         The warrants entitle Isosceles and Cefeo to purchase a total of
932,039 shares of our common stock. The warrants are exercisable until March 17,
2004 with the exercise price of $0.50 per share. The warrants also contain a
cashless exercise provision which allows the selling security holders to use the
difference between the closing price of the common stock, at the time of
exercise, minus the exercise price as a currency to acquire the shares without
paying cash. By way of example, if 1,000 shares are being exercised when the
closing price is $1.00 and the exercise price is $0.50, the selling shareholders
could use 500 shares with a market value of $500 to pay for the exercise of the
warrants. The holder would receive 500 shares net, as a result of the cashless
exercise.

         We must, however, reduce the exercise price of the warrants if we sell
shares of our common stock, grant options or adjust the exercise prices of
options or issue other securities convertible into our common stock at prices
less than $.50. We are required to pay the warrant holders a fee of up to $2,500
per day if we do not deliver the shares issuable upon exercise of the warrants
within three trading days after the warrants are exercised.

ADDITIONAL WARRANTS

         We also issued warrants to purchase an aggregate of up to 155,339
shares of our common stock at $.774 per share to Ballsbridge Finance Limited,
Elliot Layne & Associates, Inc. and Ven-Gua Capital Markets, Ltd. in
consideration for introducing Viragen to Isosceles and Cefeo. The warrants we
issued to Ballsbridge, Elliot Layne and Ven-Gua are exercisable currently until
March 17, 2004. As we did not pre-pay the notes issued to Isosceles and Cefeo,
before July 7, 1999, one-half of the warrants issued to Ballsbridge, Elliot
Layne and Ven-Gua were returned to Viragen. We entered into a registration
rights agreement with Ballsbridge, Elliot Layne & Associates and Ven-Gua similar
to the one we entered into with Isosceles and Cefeo.


         The following table sets forth as of September 24, 1999 (1) the name
of the selling security holders, (2) the amount of common stock held directly or
indirectly or underlying the notes and the warrants to be offered by the selling
security holders and (3) the amount to be owned by the selling security holders
following the sale of these shares. As of September 24, 1999, there were
outstanding 75,400,430 shares of Viragen's common stock.

         The total of 6,220,121 potential shares allocated to the selling
security holders was derived as follows:

         o  4,112,219 shares issued upon conversion of the promissory notes and
            related interest at $0.50 per share;

         o  1,098,139 shares issued under the re-set provision of the notes; and

         o  1,009,709 shares issuable upon exercise of related warrants.

expenses and fees of preparing, filing and printing the registration statement
and mailing of these items. Viragen will not pay selling commissions and

the selling security holders against civil liabilities including liabilities

                              PLAN OF DISTRIBUTION

         These shares of our common stock may be sold by the selling security
holders, or by other successors in interest. The sales may be made on one or

then current market price, or in negotiated transactions.

         The shares of our common stock may be sold by one or more of the
following methods, including, without limitation:

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

         o  purchases by a broker or dealer as principal and resale by the
            broker or dealer;

                                       48
<PAGE>   52

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

         o  face-to-face or other direct transactions between the selling
            security holders and purchasers without a broker-dealer or other
            intermediary.

         In addition, the selling security holders may, subject to the
restrictions described below and previously under "Selling Security Holders",
sell short the common stock of Viragen. In these instances, this prospectus may
be delivered in the connection with the short sale and the shares offered may be
used to cover the short sale. The selling security holders will be considered
underwriters within the meaning of the Securities Act of 1933, as amended, in
connection with the sale of the shares offered. In making sales, broker-dealers
or agents engaged by the selling security holders may arrange for other
broker-dealers or agents to participate. Broker-dealers may receive commissions
or discounts from the selling security holders in amounts to be negotiated
immediately prior to the sale. These broker-dealers and agents and any other
participating broker-dealers or agents, as well as the selling security holders
and the placement agent, will be considered to be "underwriters" within the
meaning of the Securities Act of 1933. In addition, any securities covered by
this prospectus that qualify for sale under Rule 144 may be sold under Rule 144
rather than by this prospectus.

         We informed the selling security holders that the anti-manipulative
rules under the Securities Exchange Act of 1934, including Regulation M, may
apply to their sales in the market. We have furnished the selling security
holders with a copy of these rules. We have also informed the selling security
holders that they must deliver a copy of this prospectus with any sale of their
shares.


                            DESCRIPTION OF SECURITIES

         Viragen is currently authorized to issue up to 125,000,000 shares of
common stock, par value $.01 per share, of which 75,400,430 shares were
outstanding as of September 24, 1999. Viragen is also authorized to issue up to
1,000,000 shares of preferred stock, par value $1.00 per share, of which 2,650
shares of series A preferred stock and 11 shares of series I preferred stock
were outstanding as of September 24, 1999.

COMMON STOCK

         Subject to the dividend rights of the holders of preferred stock,
holders of shares of common stock are entitled to share, on a proportionate
basis, such dividends as may be declared by the board of directors. Upon
liquidation, dissolution or winding up of Viragen, after payment to creditors
and holders of our outstanding preferred stock, Viragen's assets will be divided
proportionately on a per share basis among the holders of our common stock.

         Each share of our common stock has one vote. Holders of our common
stock do not have cumulative voting rights, which means that the holders of a
plurality of the shares voting for the election of directors can elect all of
the directors. In that event, the holders of the remaining shares will not be
able to elect any directors. Viragen's By-Laws provide that a majority of the
issued and





                                       49
<PAGE>   53

outstanding shares of our common stock are a quorum to transact business at a
stockholders' meeting. Our common stock has no preemptive, subscription or
conversion rights and is not redeemable.

PREFERRED STOCK

         Viragen is authorized to issue a total of 1,000,000 shares of preferred
stock, par value $1.00 per share. The preferred stock may be issued by
resolutions of Viragen's board of directors without any action of the
stockholders. These resolutions may authorize issuances of such preferred stock
in one or more series. In addition, they may fix and determine dividend and
liquidation preferences, voting rights, conversion privileges, redemption terms
and other privileges and rights of the shares of each authorized series.

         While Viragen includes preferred stock in its capitalization to improve
its financial flexibility, preferred stock could possibly be used by Viragen to
preserve control by present management in the event of a potential hostile
takeover of Viragen. In addition, the issuance of large blocks of preferred
stock could also have a dilutive effect to existing holders of Viragen's common
stock.

SERIES A PREFERRED STOCK

         Viragen established the series A preferred stock in November 1986. Each
share of series A preferred stock is immediately convertible into 4.26 shares of
our common stock. Dividends on the series A preferred stock are cumulative, have
priority to our common stock and are payable in either cash or common stock, at
Viragen's option.

         The series A preferred stock has voting rights only if dividends are in
arrears for five annual dividends. Upon such occurrence, the voting is limited
to the election of two directors. Voting rights terminate upon payment of the
cumulative dividends. The series A preferred stock is redeemable at the option
of Viragen at any time after expiration of ten consecutive business days during
which the bid or last sale price for our common stock is $6.00 per share or
higher. There is no mandatory redemption or sinking fund obligation for the
series A preferred stock.

         Owners of the series A preferred stock are entitled to receive $10.00
per share, plus accrued and unpaid dividends, upon liquidation, dissolution or
winding up of Viragen before any distribution or payment is made to holders of
the common stock or other stock of Viragen junior to the series A preferred
stock.

SERIES I PREFERRED STOCK

       The series I preferred stock have no dividends, although an 8% accretion
factor has been included for purposes of determining the liquidation and
conversion amounts. The series I preferred stock carries no voting rights and
has a stated value of $10,000 per share.



                                       50
<PAGE>   54

         The series I preferred stock and the 8% accretion factor is convertible
into shares of our common stock at the lower of:

         (1)  $1.59; or

         (2)  the variable conversion price which will equal 82% of the market
              price on the date of conversion.

         The amount of the shares of our common stock a holder of the series I
preferred stock may convert into is limited to a maximum of 15% of the aggregate
principal amount of the series I preferred stock issued to a holder for each
monthly period. This is subject to a maximum of 25% per monthly period if the
holder has not elected to convert the permitted 15% amount for the series during
any previous monthly conversion period. In addition, this conversion quota will
not be applicable in the event Viragen completes a private offering of its debt
or equity securities.

         At Viragen's option, any shares of series I preferred stock which are
outstanding on August 19, 2000 will either be (1) automatically converted at the
conversion rate in effect at that time or (2) automatically redeemed at $10,000
per preferred share plus any liquidated damages and any other cash payments then
due from Viragen.

         Viragen also has the right to redeem all or any part of the series I
preferred stock submitted for conversion if on the date of conversion the
conversion price of Viragen's common stock is less than $1.50. Under the right
to redeem option, if the closing bid price of the common stock on the date of
conversion is less than $1.50, the redemption price paid by Viragen to the
holder will be $11,200 per share of the series I preferred stock. On the other
hand, if the closing bid price is greater than $1.50, the redemption price paid
by Viragen to the holder will be $11,750 per share of series I preferred stock.

OVER-THE-COUNTER MARKET

         Viragen's common stock is traded on the OTC Bulletin Board. In the
event we do not maintain a minimum net tangible worth of at least $2,000,000,
our common stock will be covered by a Securities and Exchange Commission rule
that imposes additional sales practice requirements on broker-dealers who sell
such securities to persons other than established customers and accredited
investors, generally institutions with assets in excess of $5,000,000 or
individuals with net worth in excess of $1,000,000 or annual income exceeding
$200,000 or $300,000 jointly with their spouse. For transactions covered by the
rule, the broker-dealer must make a special suitability determination for the
purchaser and receive the purchaser's written agreement to the transaction prior
the sale. Consequently, the rule may affect the ability of broker-dealers to
sell Viragen's securities. It also may affect the ability of purchasers in this
offering to sell their shares in the secondary market. See the section of this
prospectus entitled "High Risk Factors" for more information on the topics
discussed above.

                         SHARES ELIGIBLE FOR FUTURE SALE

         Sales of substantial amounts of common stock in the public market
following this offering could negatively affect the market price of our common
stock and could impair our future ability to raise capital through the sale of
our equity securities.

         Upon the completion of the sale of common stock by the selling security
holders, we will have outstanding 76,410,139 shares of common stock. Of these
shares, approximately:

         o    69,562,519 shares will be freely tradable by persons, other
              than "affiliates," without restriction under the Securities Act of
              1933; and

         o    6,847,620 shares will be "restricted" securities, within the
              meaning of Rule 144 under the Securities Act of 1933, and may not
              be sold in the absence of registration under the Securities Act of
              1933 unless an exemption from registration is available, including
              the exemption provided by Rule 144.

         In general, under Rule 144 as currently in effect, a person or persons
whose shares are aggregated, including any affiliate of Viragen who has
beneficially owned restricted securities for at least one year, would be
entitled to sell within any three-month period, a number of shares that does not
exceed 1% of the number of common stock then outstanding. This would be
approximately 764,101 shares immediately after the completion of this offering.

         Sales under Rule 144 are also subject to manner of sale and notice
requirements and to the availability of current public information about
Viragen. Under Rule 144(k), a person who is not considered to have been an
affiliate of Viragen at any time during the 90 days preceding a sale, and who
has beneficially owned restricted securities for at least two years, including
the holding period of any prior owner except an affiliate of Viragen, may sell
these shares without complying with the manner of sale, public information
requirements volume limitations or notice requirements of Rule 144. Sales of
shares by affiliates will continue to be subject to these volume limitations,
and manner of sale, notice and public information requirements.

                                  LEGAL MATTERS

         The validity of the issuance of the shares of our common stock being
offered hereby will be passed upon by Atlas, Pearlman, Trop & Borkson, P.A., 200
East Las Olas Boulevard, Suite 1900, Fort Lauderdale, Florida 33301. Members of
that firm or members of their family own a total of 37,000 shares of our common
stock.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

Shareholders and Board of Directors
Viragen, Inc.

     We have audited the accompanying consolidated balance sheets of Viragen,
Inc. and subsidiaries as of June 30, 1999 and 1998, and the related consolidated
statements of operations, stockholders' equity and cash flows for each of the
three years in the period ended June 30, 1999. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these 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 financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Viragen, Inc. and subsidiaries at June 30, 1999 and 1998, and the consolidated
results of their operations and their cash flows for each of the three years in
the period ended June 30, 1999, in conformity with generally accepted accounting
principles.

     The accompanying consolidated financial statements have been prepared
assuming that Viragen Inc. and subsidiaries will continue as a going concern. As
discussed in Note A to the consolidated financial statements, the Company has
incurred recurring operating losses and has an accumulated deficit of
approximately $51 million at June 30, 1999. These conditions raise substantial
doubt about the Company's ability to continue as a going concern. Management's
plans in regard to these matters are also described in Note A. The consolidated
financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                             JUNE 30, 1999 AND 1998

NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Consolidation and Basis of Presentation: Viragen, Inc. and its subsidiaries
are engaged in the research, development and manufacture of certain
immunological products for commercial application. The consolidated financial
statements include the parent company and all subsidiaries, including those
operating outside the U.S. All significant transactions among our businesses
have been eliminated. We made certain reclassifications to the 1998 and 1997
financial statements to conform to the 1999 presentation.

     Viragen owns a 10% equity interest in Inflammatics, Inc., a
biopharmaceutical company currently in the research and development stage. While
we have the option to increase our ownership interest up to 80%, the financial
accounts of Inflammatics are not consolidated with those of Viragen. We account
for our investment under the equity method of accounting. The parties that own
the remaining 90% equity in Inflammatics are not currently funding its research
and development efforts. Accordingly, while Viragen only owns 10% of
Inflammatics, it is recognizing 100% of the losses incurred by the
unconsolidated company. Viragen is also expensing its excess investment costs
ratably, as research is performed by Inflammatics.

     In preparing the financial statements, management must use some estimates
and assumptions that may affect reported amounts and disclosures. Estimates are
used when accounting for depreciation, amortization, and asset valuation
allowances. We are also subject to risks and uncertainties that may cause actual
results to differ from estimated results such as changes in the health care
environment, competition, foreign exchange and legislation.

     During fiscal 1999 Viragen incurred a loss of $10,650,832 and had negative
operating cash flow of $8,955,434. As a result, our accumulated deficit
increased to $50,521,028. These operating results were caused by a lack of
regulatory approval for the sale of our products. Management has plans to
increase working capital by its efforts related to obtaining additional capital
funding. Viragen's ability to continue as a going concern is dependent on the
availability of additional capital funding, regulatory approval of our
pharmaceutical products, and adequate downsizing to operate at a reduced level
of expense. Management plans to continue to pursue available funding and adjust
operating expenses accordingly. The Company's financial statements have been
prepared assuming it will continue as a going concern and do not reflect any
costs or charges that could result from this uncertainty.

     Cash and Cash Equivalents: Cash equivalents include demand deposits,
certificates of deposit and time deposits with maturity periods of three months
or less when purchased.

     Marketable Securities, Available-for-Sale: Viragen invests in debt
securities, rated A or better, issued by the U.S. Treasury, other U.S.
government agencies and corporations. These investments are classified as
current assets, in accordance with ARB No. 43, at their fair market value based
upon published quotations. Amortized cost of the investment in marketable
securities, available-for-sale totaled $6,108,503 at June 30, 1998. Realized
gains and losses are computed based on the cost of securities sold using the
specific identification method.

     Financial Instruments: The carrying amount of financial instruments
including cash and cash equivalents, marketable securities, and accounts payable
approximate fair value as of June 30, 1999. The Company's long-term unsecured
note with the Scottish Regional Development Authority approximates fair value as
it had been recently negotiated at June 30, 1997.

     Property, Plant and Equipment: Property, plant and equipment is stated at
the lower of cost or net realizable value. Depreciation was computed by using
the straight-line method over the estimated useful life for financial reporting
purposes and using accelerated methods for income tax purposes. The estimated
useful lives used for financial reporting purposes are:

     Convertible Debt Issued with Stock Purchase Warrants: Viragen accounts for
convertible debt issued with stock purchase warrants in accordance with APB
14 -- "Accounting for Convertible Debt and Debt Issued with Stock Purchase
Warrants." At June 30, 1999, the $2,000,000 principal in convertible notes is
being off-set by $70,123 in unamortized discount from the issuance of detachable
warrants.

     Accrued Expenses and Other Liabilities: Accrued expenses and other
liabilities consisted of the following at June 30, 1999 and 1998:

</TABLE>

     Deferred Income: Viragen had deferred the recognition of income from an
option fee until the period in which it is was earned.

     Sale of Stock by Subsidiaries: Viragen accounts for sales of stock by its
subsidiaries as capital transactions for financial reporting purposes.

     Foreign Currency Translation: For foreign operations, local currencies are
considered their functional currencies. Viragen translates assets and
liabilities to their U.S. dollar equivalents at rates in effect at the balance
sheet date and record translation adjustments in stockholders' equity. Statement
of operations accounts are translated at average rates for the period.
Transaction adjustments, which are not material, are recorded in results of
operations.

     Research and Development Costs: Viragen accounts for research and
development costs in accordance with SFAS No. 2 -- "Accounting for Research and
Development Costs." Accordingly, all research and development costs are expensed
as incurred.

     Stock Based Compensation: Viragen accounts for stock-based compensation
plans under the provisions of APB 25 -- "Accounting for Stock Issued to
Employees" and, accordingly, recognizes no compensation expense for stock option
grants where the exercise price equals or exceeds fair market value at date of
grant.

                         VIRAGEN, INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

The Company provided supplemental disclosures as required by the provisions of
SFAS 123 -- "Accounting for Stock-Based Compensation."

     Income Taxes: Deferred income taxes at the end of each period are
determined by applying enacted tax rates applicable to future periods in which
the taxes are expected to be paid or recovered to differences between financial
accounting and tax basis of assets and liabilities.

     Loss Per Common Share: Loss per common share has been computed based on the
weighted average number of shares outstanding during each period, in accordance
with SFAS 128 -- "Earnings per Common Share." The effect of convertible debt and
equity securities, warrants, and options are antidilutive. As a result, diluted
loss per share data does not include the assumed conversion of these instruments
and has been presented jointly with basic loss per share. Loss attributable to
common stock reflects adjustments for cumulative preferred dividends, as well as
embedded dividends arising from discounted conversion terms on convertible
preferred stocks and related warrants.

     Embedded dividends included in loss attributable to common stock during
each fiscal year presented are:

     Comprehensive Loss.  In June 1997, the Financial Accounting Standards Board
issued SFAS No. 130 -- "Reporting Comprehensive Income." Viragen's SFAS No. 130
establishes standards for reporting and display of comprehensive income and its
components in financial statements. The adoption of SFAS No. 130 had no impact
on Viragen's net loss or stockholders' equity. Viragen's comprehensive loss for
fiscal years 1999, 1998, and 1997 totaled $10,889,070, $7,834,003 and
$4,555,445, respectively.

     Recent Pronouncements: In June 1998, the Financial Accounting Standards
Board issued SFAS No. 133 -- "Accounting for Derivative Instruments and Hedging
Activities" which is effective for fiscal quarters of fiscal years beginning
after June 15, 1999. This statement establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts and for hedging activities. It requires that an
entity recognize all derivatives as either assets or liabilities in the balance
sheet and measure those instruments at fair value. This statement amends SFAS
No. 52 -- "Foreign Currency Translation", and supersedes SFAS No. 80 --
"Accounting for Future Contracts", No. 105 -- "Disclosure of Information about
Financial Instruments with Off-Balance-Sheet Risk and Financial Instruments with
Concentration of Credit Risk", No. 107 -- "Disclosures about Fair Value of
Financial Instruments". Viragen plans to adopt SFAS No. 133 in fiscal 2000.

     Management believes that the impact of SFAS No. 133 will not be significant
to Viragen.

NOTE B -- REDEEMABLE PREFERRED STOCK

     Series G

     In September 1997, Viragen concluded an exchange agreement whereby 4,000 of
the outstanding shares of the series E preferred stock were exchanged for a like
number of series G preferred shares. The terms of the series G preferred stock
provided that commencing in September 1997, the holder was limited to converting

                                      F-12

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

667 preferred shares, or $667,000 in principal, per month over a 6 month period.
The provisions further provided that we were required to redeem $667,000 per
month less the number of series G preferred shares converted during the
preceding calendar month. In addition, the holder was restricted from converting
into common stock if the market price of our common stock was less than $2.50,
subject to adjustment, at the date of the conversion notice. In consideration
for the restrictions on conversion, management agreed to increase the dividend
rate from 5% for the series E preferred stock to 10% for the series G preferred
stock.

     The monthly redemption amount of the series G preferred stock was
calculated by dividing the number of shares to be redeemed by the preferential
conversion rate of 85%. As a result, the maximum aggregate redemption could have
totaled $4,705,882, if all 4,000 shares of series G preferred stock were
redeemed by the holder. This cash redemption amount would have been reduced to
account for conversions of the preferred shares during the redemption period.
All shares of series G preferred stock were redeemed for cash or converted into
common stock by February 28, 1998.

  Series H and Series I

     During the third and fourth fiscal quarters of 1998, Viragen closed $7
million of financing replacing a portion of the funds used to redeem previous
preferred stock issuances. In February 1998, we received net proceeds of
approximately $4,625,000 from the sale of 500 shares of series H convertible
preferred stock with an aggregate stated value of $5 million. In April 1998,
Viragen received net proceeds of approximately $1,840,000 from the sale of 200
shares of series I convertible preferred stock. We incorporated certain
restrictions as part of the series H and series I preferred stock designations
which, in the opinion of management, would facilitate a more orderly market
relative to the underlying shares of our common stock. The series H and series I
preferred stock bear no dividends although, upon liquidation or conversion, an
8% accretion factor is included in the calculation for purposes of determining
the liquidation and conversion amount.

     Neither the series H preferred stock nor the series I preferred stock
issuances were convertible until August 19, 1998, the six month anniversary of
the Series H closing. The conversion price is the lower of (1) $1.59 per share,
and (2) the variable conversion price which is equal to 82% of the market price
at the date of conversion. Management retained the right to redeem both
issuances of preferred stock at various prices upon receipt of a notice of
conversion.

     In addition, the right of conversion was further limited to a maximum of
15% of the aggregate principal amount of the series H and series I preferred
stock issued to each holder for each one month period cumulatively to a maximum
of not in excess of 25% for such month in the event the holder has converted
less than 15% in any of the preceding months.

     The series H preferred stock and series I preferred stock have certain
events of default which include bankruptcy or the failure of the Company to (1)
remain qualified for trading; (2) convert preferred shares to common stock; and
(3) maintain an effective registration statement. Upon the occurrence of an
event of default, the holders of the series H preferred sock and series I
preferred stock have the right to redeem all or any portion of the then
outstanding amount. The amount outstanding is calculated as the greater of 1.3
times the value of the preferred stock for which demand is being made plus the
accreted but unpaid amounts, calculated at 8%, earned on the preferred stock
plus liquidated damages and other cash payments then due or the product of the
highest price at which Viragen's common stock is traded on the date of an event
of default divided by the conversion price as of that date and the amount being
redeemed. Since the 8% accretion is due upon mandatory redemption, the Company
has increased the carrying amount of the Series H Preferred Stock and Series I
Preferred Stock by this amount.

     Pursuant to the terms of the subscription agreements, the holders of the
series H and series I preferred stock also received Nine Month warrants, Twelve
Month warrants and Fifteen Month warrants to purchase

     The Nine Month, Twelve Month, and Fifteen Month warrants are exercisable
through February 17, 2003.

     The series H and series I placement agent received a commission of $490,000
for the placement of the series H preferred stock and H warrants and series I
preferred stock and I warrants. In addition, the placement agent received
placement agent warrants to purchase an aggregate of 402,052 shares of common
stock, which were subsequently transferred to affiliates and employees of the
placement agent. The placement agent warrants entitle the holders thereof to
exercise those warrants at an exercise price of $1.684 per share at any time
between the date of their respective issuances and February 19, 2003; provided
that if the date of exercise occurs after February 19, 1999, the exercise price
of the placement agent warrants will be the lesser $1.684 per share or the
lowest reset price as calculated on each one year anniversary of the date of
issuance during the warrant term.

NOTE C -- CAPITAL STOCK

PREFERRED STOCK

  Series A

     The series A preferred stock provides for a 10% cumulative dividend,
payable at the option of Viragen, in either cash or common stock and is
convertible into 4.26 shares of common stock. The holders of the series A
preferred stock are not entitled to vote unless dividends are in arrears for
five annual dividend periods. Management has the right to call the preferred
stock for redemption, in whole or in part, if the closing bid for common stock
is $6.00 per share or higher for a period of ten consecutive business days, at
$11.00 per share for a period of five years from that date, and then at $10.00
per share.

  Series B

     On June 7, 1996, Viragen entered into a securities purchase agreement with
GFL Performance Ltd., GFL Advantage Fund Ltd. and Proton Global Asset
Management, LDC pursuant to which they acquired 15,000 shares of 5% cumulative
convertible preferred stock, series B for $15 million.

     In connection with the sale and issuance of the series B preferred stock,
we issued warrants to purchase 225,000 shares of common stock at $10.59 per
share for a period of 3 years from date of issuance. Viragen also paid
approximately $900,000 in cash fees to certain finders and an investor
representative who participated in the transaction plus certain additional
expenses. These costs were netted against the proceeds of the sale. All of the
warrants expired on June 6, 1999.

     The series B preferred stock provided for a cash dividend equal to 5% of
the stated value of the series B preferred stock, although management had the
option to utilize shares of common stock, under certain conditions, to satisfy
the dividend requirement. The investors had the right to convert the series B
preferred

stock into shares of common stock at a conversion price equal to the lesser of
76.8% of the average market price of Viragen's common stock, as described in the
securities purchase agreement, prior to the conversion date, or $8.74. In July
1997, the unconverted series B preferred stock was exchanged for a promissory
note in the amount of $9,720,241. The note provided for interest at 10% per
annum with principal and interest payable over nine monthly installments
commencing in October 1997.

     The note could be prepaid without penalty and was not convertible into
common stock. The principal value of the note was comprised of the following
components:

The note was paid-in-full in April 1998.

  Series C

     In December 1996, Viragen issued 5,000 shares of its series C convertible
preferred stock in consideration for $4,740,923, net of issuance costs totaling
$259,077. The purchases were made by Strome Hedgecap Limited, Strome Offshore
Limited, Strome Partners, L.P. and Strome Susskind Hedgecap, L.P., pursuant to
separate securities purchase agreements. In addition, warrants to purchase an
aggregate of 214,593 shares of common stock, exercisable at $2.00 per share on
or prior to December 9, 1999, were issued to the purchasers of the series C
preferred stock.

     The terms of the series C preferred stock provided that up to 25% of the
series C preferred stock could be converted into common stock on or after 10
days from the date the registration statement registering the underlying shares
was deemed effective by the Securities and Exchange Commission. Thereafter 25%
could be converted on or after the 30th, 60th and 90th day on a cumulative
basis. The preferred stock was convertible into a number of common shares
determined by dividing the stated value of the series C preferred stock, or
$1,000 per share, by the closing price of Viragen's common stock over the five
day period preceding notice of conversion. The conversion price could not be
less than $3.46 nor more than $7.00. In the event the conversion price fell
below $3.46, the difference between $3.46 and the conversion price would be paid
to the holder in cash. Any shares of series C preferred stock which were
outstanding on December 5, 1997 would be automatically converted into shares of
common stock based on the conversion price at that time in accordance with the
above procedures.

     In July 1997, the holders of the series C preferred stock agreed to modify
their conversion price and limit conversions of their remaining 974 shares over
a two month period. The modified conversion price was the lower of (1) $2.20 per
share or (2) the average closing price of Viragen's common stock over the five
day period ending the day prior to the notice of conversion. The terms
addressing conversions below $3.46 contained in the original agreement were not
modified. As a result, we were committed to refund a minimum of $354,694 to the
series C purchasers, upon conversion of the remaining series C preferred stock.
The refund amount would increase if conversions occurred below $2.20. All shares
of series C preferred stock were converted into common stock by December 31,
1997. During fiscal 1998, we paid $1,391,198 in capital refunds to the series C
purchasers. Of the total refunds, $553,041 were related to conversions,
occurring under the modified terms, during fiscal 1998. The balance of $838,157
related to conversions, under the original terms, during the end of fiscal 1997.

  Series D and Series F

     In February 1997, Viragen issued 15,000 shares of its 6% series D
convertible preferred stock to P.R.I.F., L.P. in consideration for $14,050,349,
net of issuance costs totaling $949,651. The series D preferred sock was
convertible into a number of shares of common stock determined by dividing the
five day trading average price

of our common stock prior to conversion, discounted by 18%, into the stated
value of the preferred shares being converted. In connection with the issuance
of the series D preferred stock, we also issued 375,000 common stock purchase
warrants, exercisable at $6.00 per share. All of the warrants expired on June
30, 1998.

     In September 1997, we concluded an exchange agreement whereby the series D
preferred stock were exchanged for series F preferred shares. The series F
preferred stock provided for a restriction on the holder limiting conversion
during any two week period to 800 preferred shares, or $800,000 in principal.
The terms also provided management with a cash-out option at the face amount
being converted plus 12%. In consideration for the holder of the series D
preferred stock agreeing to a limitation on future conversions, we agreed to
increase the dividend rate from 6% for the series D preferred stock to 10% for
the series F preferred stock. All shares of series F preferred stock were
redeemed for cash or converted into common stock by March 31, 1998. During
fiscal 1998, Viragen paid $2,744,000 to the series F holder upon exercise of the
cash-out option on conversions.

  Series E

     In February 1997, Viragen also issued 5,000 shares of its 5% series E
convertible preferred stock in consideration for $4,681,744, net of issuance
costs totaling $318,256. Dividends on the series E preferred stock accrued from
the date of issuance and were payable quarterly commencing April 1, 1997.
Dividends were payable in cash or, at management's option and subject to certain
other conditions, in shares of common stock.

     The series E preferred stock was convertible into shares of common stock
commencing May 11, 1997 at a conversion price of the lesser of (1) the average
market price for the five trading days prior to the notice of conversion
multiplied by 85%, subject to adjustment, or (2) $7.00, subject to adjustment.

COMMON STOCK

     During May 1999, Viragen completed a private placement for the sale of
2,750,000 shares of common stock. The common shares were sold to three
accredited investors at $0.50 per share. Viragen received proceeds of $1,375,000
from the sale of these shares.

     At our 1998 annual stockholders' meeting, which was concluded on July 19,
1999, the stockholders approved the following proposals:

     (1) authorization for up to a 1-for-8 reverse stock split; and

     (2) an increase in the number of authorized common shares, if the board of
         directors did not effect the reverse split.

     On August 13, 1999, the board of directors elected to increase the
authorized common shares up to 125,000,000 shares.

OPTIONS AND WARRANTS

     Under Viragen's 1995 stock option plan, 4,000,000 shares of common stock
were reserved for issuance to officers, directors, employees and consultants of
Viragen for stock options designated as incentive stock options within the
meaning of Section 422 of the Internal Revenue Code. Options granted under the
1995 stock option plan have various vest dates and all options granted have
five-year terms from the vesting date.

     Viragen's 1997 incentive stock option plan, adopted during February 1997,
authorized the grant of options to management personnel, directors and employees
for up to 3,000,000 shares of common stock. In April 1998, the 1997 stock option
plan was amended increasing the number of common shares authorized to 4,000,000
shares. Options granted under the plan have various vest dates and all options
granted have 5 year terms from the vesting date.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     During fiscal 1997, we granted a total of 2,941,500 options to purchase
Viragen common stock. Of these, 1,750,000 were granted to our officers and
directors. The options vested immediately and are exercisable for a period of
five years. The exercise price on these options is $3.22, which was market price
at the date of grant.

     During fiscal 1997, Viragen also granted options to an officer and an
employee, with exercise prices below market price. The total options granted
were for 400,000 shares. The Company recognized an expense of $381,500 related
to the granting of these options.

     During fiscal 1997, we granted 120,000 options that were not part of the
above stock option plan to an employee. The options vested immediately and have
a 5 year term from that date.

     Viragen issued 518,229 shares of common stock upon the conversion and
exercise of stock options and warrants during fiscal 1997. Proceeds from these
issuances totaled $371,337.

     During fiscal 1998, management granted a total of 367,500 options to
employees. The options vest over various dates and are exercisable for five
years from the vesting dates. The exercise prices of these options, which
represent the market price at the date of grant, range from $1.50 to $2.50 per
share. Viragen also granted 50,000 options to a director. The options vested
immediately and are exercisable at $1.19 per share, which was the market price
at the date of grant, for a period of five years.

     Viragen also issued 32,000 warrants during fiscal 1998 to a consultant as
compensation for services provided. The warrants are exercisable at $1.00 per
share for a period of five years.

     During fiscal 1998, we issued 230,565 shares of common stock upon the
exercise of options and warrants. Viragen received $117,888 upon exercise of
these options and warrants.

     During fiscal 1999, Viragen granted an aggregate of 85,000 options to one
officer and two directors. The options have exercise prices ranging between
$0.41 and $1.81, which represented market price on the date of grant. These
options vest over various dates and are exercisable for five years from the
vesting dates. Three employees were also granted a total of 9,000 options with
exercise prices ranging between $1.75 and $1.87. The options, which vest over
various dates, are exercisable for five years from the vesting dates.

     Viragen issued 1,245,000 common stock warrants to consultants during fiscal
1999. The warrants were issued as compensation for services provided to the
company during the year. The warrants vest over various dates, subject to
performance provisions, and have exercise prices ranging from $0.50 to $11.00.

     During fiscal 1999, Viragen issued 1,488,473 shares of commons stock from
the exercise of options and warrants. We received $253,489 in cash and $602,000
was secured by promissory notes and related pledge and escrow agreements.

     At June 30, 1999, 35,000 shares and 926,000 shares remain available under
the 1995 and the 1997 stock option plans, respectively.

STOCK BASED COMPENSATION

     Viragen has elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" and related Interpretations in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under SFAS No. 123 -- "Accounting
for Stock-Based Compensation" requires use of option valuation models that were
not developed for use in valuing employee stock options. Under APB 25, Viragen
recognized compensation expense in the amount of $172,000, $-0- and $450,000 in
1999, 1998 and 1997, respectively, because the exercise price of a portion of
the company's employee stock options was less than the market price of the
underlying stock on the date of grant. During 1999, 1998 and 1997, we recognized
approximately $199,000, $58,000 and $-0- in compensation expense on warrants
granted to consultants pursuant to SFAS 123, respectively.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Pro forma information regarding net income and earnings per share is
required by SFAS 123, and has been determined as if we had accounted for our
employee stock options under the fair value method of that statement. The fair
value for these options was estimated at the date of grant using a Black-Scholes
option pricing model with the following weighted-average assumptions: dividend
yield of zero percent for all periods; expected life of the option of 3 years;
risk-free interest rates within a range of 5.60% to 6.00%; and a volatility
factor of the expected market price of Viragen's common stock of .77, .75 and
 .64 for 1999, 1998 and 1997, respectively.

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because Viragen's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options and warrants.

     Based on calculations using a Black-Scholes option pricing model, the
weighted average grant date fair value of options was $0.57, $1.10 and $1.51 in
fiscal 1999, 1998 and 1997, respectively. The pro forma impact on Viragen's net
loss per share had compensation cost been recorded as determined under the fair
value method is shown below.

NOTE D -- INVESTMENT IN UNCONSOLIDATED COMPANY

     In August 1998, Viragen entered into a strategic alliance concurrent with
the purchase of a 10% equity interest in Inflammatics, Inc., a private drug
development company headquartered in Philadelphia, PA. Inflammatics is focused
on the development of therapeutic drugs for autoimmune disorders. Its lead
product is LeukoVAX, an immunomodulating leukocyte preparation currently in Food
and Drug Administration Phase I/II clinical trials for rheumatoid arthritis.

     Under the terms of the Inflammatics agreement, Viragen made an initial
investment in the form of series A convertible preferred stock of Inflammatics
for $1 million and warrants to purchase 250,000 shares of common stock at prices
ranging between $1.00 and $1.78 per share. Viragen further obtained two options
to acquire an additional 70% equity position in Inflammatics through two
additional fundings to be made at our option. The first additional funding,
subject to management's evaluation of the Phase I/II clinical trial results,
provides for the issuance of 1,000,000 shares of common stock, the issuance of
300,000 commons stock purchase warrants exercisable at $1.00 through August 14,
2003, and the underwriting of Phase III clinical trials, in exchange for an
additional 36.3% equity interest. Preliminary estimates for the funding of Phase
III clinical trials of LeukoVAX range between $6.0 million and $10.0 million.
The second additional funding,

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

subject to management's further evaluation of clinical trial results, provides
for the issuance of an additional 2,000,000 shares of commons stock in exchange
for an additional 33.3% equity interest.

     The investment in Inflammatics was capitalized at $1,429,000, which
consisted of the $1,000,000 paid to Inflammatics, a $100,000 finders fee paid to
Sumitomo Bank, and $329,000 in costs associated with the warrants issued, which
were valued using a Black-Scholes valuation model.

     Viragen recognized approximately $757,000 in losses related to its
investment in Inflammatics, Inc. during the fiscal year ended June 30, 1999.
This loss reflects 100% of the losses incurred by Inflammatics associated with
the clinical testing of LeukoVAX. The loss also includes the expensing of our
excess investment costs.

NOTE E -- CONVERTIBLE NOTES WITH DETACHABLE WARRANTS

     On March 17, 1999, we entered into a purchase agreement with the Isosceles
Fund Limited and Cefeo Investments Limited, which was subsequently amended on
June 16, 1999. Under the purchase agreement, we issued Isosceles and Cefeo 8%
convertible promissory notes in the aggregate principal amount of $2,000,000
with detachable warrants to purchase 932,039 shares of our commons stock.
Viragen received $1,861,820 from the issuance of the convertible notes and
detachable warrants. The proceeds were net of $138,180 paid as finders' fees. As
required by APB Opinion No. 14 -- "Accounting for Convertible Debt and Debt
Issued with Stock Purchase Warrants", we valued the detachable warrants using a
Black-Scholes valuation model. The model valued the detachable warrants at
$344,854, which was recorded as a discount on principal.

     Subsequent to June 30, 1999, one-half of the principal balance, which
accrued interest at a rate of 8% annually, and accrued interest on the related
principal converted automatically into 2,049,534 shares of our common stock on
July 7, 1999. In addition, the remaining one-half of the principal balance and
accrued interest on the notes converted automatically into 2,062,685 shares of
our common stock on August 6, 1999. The conversion price was $0.50 per common
share.

     In addition to the shares issued on conversion of the notes, the note
holders were entitled to receive additional shares of our common stock 30 days
after each one-half of the notes converted into shares of our common stock, as
required by a re-set provision. The purpose of this arrangement was to make sure
that the note holders had a return of at least 20% on the shares received on the
conversion of the first half of the notes and at least a 22% return on the
conversion on the remaining half of the notes. The number of additional shares
to which the note holders were entitled was calculated by dividing $0.644 by the
lowest closing bid price of our common stock during the ten consecutive trading
days preceding each re-set date.

     On August 6, 1999, Isosceles and Cefeo received an aggregate amount of
546,990 additional common shares, based on the first re-set calculation. These
shares were issued using a future price of $0.61 per share. On September 5,
1999, Isosceles and Cefeo received an aggregate amount of 551,203 additional
common shares, based on the second re-set calculation. These shares were issued
using a future price of $0.62 per share. Viragen will recognize approximately
$700,000 in interest expense during the first quarter of fiscal 2000, as a
result of issuing these additional shares.

     The warrants issued to Isosceles and Cefeo to purchase an aggregate of
932,039 shares of our common stock are exercisable until March 17, 2004 with an
exercise price of $.50 per share. However, we must reduce the exercise price of
the warrants if we sell shares of our common stock, grant options or adjust the

stock at prices less than $.50 per common share.

     We also issued warrants to purchase an aggregate of up to 155,339 shares of
our common stock at $.773 per share to certain parties in consideration for
introducing Viragen to Isosceles and Cefeo. The warrants issued are exercisable
currently until March 17, 2004. As we did not pre-pay the notes issued to
Isosceles and Cefeo before July 7, 1999, one-half of these warrants were
returned to Viragen.

     The change in the valuation allowance was a net increase of $2,296,000 for
the year ended June 30, 1999.

     Viragen has undergone two ownership changes, as defined by Internal Revenue
Code Section 382, which will cause the utilization of the net operating losses

NOTE H -- TRANSACTIONS WITH RELATED PARTIES

     In June 1996, Viragen loaned $50,000 to a now-former employee. The
promissory note is for a term of five years with an annual interest rate of
6.48%. Interest is to be paid semi-annually with the principal balance and
unpaid interest payable on the fifth anniversary of the note. Management has
reserved approximately $25,000 of the principal balance as uncollectable at June
30, 1999. Management intends to pursue collection of this promissory note.

     In November 1996, Viragen forgave a $12,500 balance due to the company by
its chief executive officer.

     In April 1997, management loaned $100,000 to one of Viragen's directors.
The secured promissory note is for a term of one year with the principal and
interest payable upon maturity. The note bears interest at 8.50% per annum. In
April 1998, the director defaulted on the note. Management is unable to
ascertain the amounts,

if any, which could ultimately be realized on the promissory note. Accordingly,
the entire amount due under the note with related accrued interest of
approximately $10,000 was been written-off as uncollectable on June 30, 1998.
Management intends to pursue collection efforts relative to this transaction.

     On July 31, 1998, we held our 1997 annual shareholders meeting. Certain
directors did not seek reelection to serve as directors of the company. In
appreciation of their past service, Viragen waived the requirement to exercise
outstanding stock options within 90 days of their last day as directors. All
outstanding stock options will expire under their normal terms. We recognized
approximately $199,000 in compensation expense upon waiving the 90-day
expiration clause.

     During fiscal 1999, certain directors and former officer exercised
1,160,000 options to purchase common stock at prices ranging between $0.30 and
$1.19 per share. The options were exercised through the issuance of promissory
notes payable to Viragen with related pledge and escrow agreements. The
promissory notes bear interest at rates ranging between 5.06% and 5.47%, payable
semi-annually and are secured by the underlying common stock purchased. The
shares are being held in escrow pending payment of the related notes pursuant to
the provisions of the pledge and escrow agreements.

NOTE I -- COST REDUCTION PLAN

     During fiscal 1999, Viragen began implementing a cost-reduction plan
targeted to reduce domestic and research costs. These changes in operations
reflect our shift from developing our product in our domestic laboratories to
scale-up development and clinical research in our European facility.

     SFAS No. 121 -- "Accounting for the Impairment of Long-Lived Assets"
requires impairment losses to be recorded on long-lived assets when indicators
of impairment are present and the undiscounted cash flows estimated to be
generated by those assets are less then the assets' carrying amount. EITF 94-3
- -- "Liability Recognition for Certain Employee Termination Benefits and Other
Costs to Exit an Activity" requires restructuring costs to be accrued under
specific guidelines.

     No losses or exit costs have been accrued by Viragen. We have not done so
because the criteria for recognizing losses and exit costs, as specified in SFAS
121 and EITF 94-3, have not been met.

     Much of the savings to be realized from personnel reductions comes from the
elimination of positions where employment agreements have expired. Accordingly,
these individuals are not receiving severance pay. Of the remaining positions to
be eliminated, management has not yet approved any severance packages to be
offered.

     Viragen is not aware of any impairment of its equipment, and accordingly,
we have not recognized any loss due to impairment on our long-lived laboratory
equipment or facility. Upon termination of research activities in our domestic
facility, equipment considered to be useful to our Scottish operations will be
transferred to our Scottish facility, where it will be used in continuing
research activity, as well as manufacturing and quality assurance operations.
Equipment identified for disposal, if any, will be sold for the highest bid.
Viragen has not yet identified any equipment for disposal, and accordingly, has
not recognized any impairment. We are currently in the process of trying to sell
the domestic research facility, but no impairment has been recorded because an
independent appraisal performed has valued the land, building and related
improvements above its net book value.

NOTE J -- LICENSE AND MANUFACTURING AGREEMENTS

     Through a fifteen-year license agreement granted by Viragen, Viragen
(Europe) Ltd. and its wholly-owned subsidiary, Viragen (Scotland) Ltd., secured
certain rights to engage in the research, development, and manufacture of
certain proprietary products and technologies that relate to the therapeutic
application of human leukocyte-derived interferon for various diseases that
affect the human immune system. Pursuant to these rights, on July 20, 1995,
Viragen (Scotland) entered into a license and manufacturing agreement with the
Common Services Agency, an agency acting on behalf of the Scottish National
Blood Transfusion Service. The Transfusion Service, on behalf of Viragen
(Scotland), will manufacture and supply Viragen (Scotland)'s product to Viragen
(Scotland) for distribution in the European Union in return for certain fees. It
was considered critical to our operations and to planned clinical trials to
secure a sufficient qualified source of human source leukocyte, a critical
component in the manufacture of the product. Viragen (Scotland) commenced
operations concurrent with the execution of its agreement with the Transfusion
Service. The term of the Scottish agreement is five years with two additional
five-year extension terms exercisable at the option of Viragen (Scotland).

     Pursuant to the terms of the license, Viragen (Scotland) was to prepay $2
million to Viragen, within six months of the effective date, July 12, 1995.
Commencing one year from the effective date, Viragen (Scotland), is to pay to
Viragen fees, as follows: the greater of $2 million annually or 10% of gross
revenues until the sum of $18 million has been paid; 8% of gross revenues until
the sum of $25 million has been paid; and 5% of gross revenues thereafter. The
license will renew automatically for two consecutive fifteen-year terms.

     Both parties modified the license deferring the initial payment until the
date when Viragen transferred the processes and technology, as defined by the
license, to Viragen (Scotland). Viragen had substantially transferred the
processes and technology to Viragen (Scotland) by the end of May 1997. At that
time, Viragen required the initial royalty payment be made. Completion of the
transfer occurred on November 1, 1997.

     In April 1998, Viragen entered into an option agreement with Southern
Health SDN.DHD, a private Malaysian/Australian-based healthcare investment
group. The option agreement initially provided Southern Health the right to
acquire, through September 30, 1998, subsequently extended to March 31, 1999, an
exclusive, private-label manufacturing and distribution license covering
Malaysia, Indonesia, the Philippines, Thailand, Taiwan, Korea, Singapore,
Australia and New Zealand, for our proprietary natural interferon production
process in exchange for an initial cash licensing fee of $20 million and a
continuing royalty of 12% of Southern Health's related revenues. Southern Health
paid a $200,000 option fee.

     On March 31, 1999, the option agreement expired, without being exercised.
We recognized one-half of the fee, or $100,000, as revenue, and the balance was
refunded to Southern Health during April 1999.

NOTE K -- RESEARCH AND DEVELOPMENT AGREEMENTS

     Viragen has a contract with Viragen Research Associated Limited
Partnership, for Viragen to perform the research and development with respect to
two therapeutic products for the topical treatment of herpes virus infections.
Pursuant to the contract, we assigned all of our patent rights to the processes
and topical products to Viragen Research Associated in exchange for an exclusive
worldwide licensing agreement. Viragen Research Associated is to receive 5% of
the gross revenues of such products until it has received approximately $900,000
and, thereafter, it is to receive 2% of the gross revenues of such products.
Viragen is not presently pursuing the development or commercialization of a
topically applied product.

NOTE L -- ROYALTY AGREEMENT

     Viragen has a royalty agreement with Medicore, Inc. that will pay Medicore
a maximum of $2,400,000 in royalties. Royalties are to be paid as follows: 5% on
the first $7 million of sales of interferon and related

products; 4% of the next $10 million of sales; and 3% on the next $55 million of
sales up to the maximum of $2,400,000 in royalty payments. Royalties incurred in
prior years under the agreement, totaling approximately $108,000, are included
in royalties payable. This amount will be paid as the final payment under the
royalty agreement.

NOTE M -- COMMITMENTS

     In November 1996, Viragen (Scotland) Ltd. executed a five-year lease on
property located in Edinburgh, Scotland that will serve as our laboratory and
production facilities. Base monthly rental on the property is approximately
$9,975. In addition, Viragen (Scotland) may extend the term of the lease at its
option, for four five-year periods.

     In November 1996, Viragen entered into a ten-year lease on property in
Plantation, Florida. This facility contains our executive and administrative
offices. Monthly rental on the property is approximately $15,700. The lease
contains provisions for two additional five-year periods at the Company's
option.

     During the years ended June 30, 1999, 1998 and 1997, Viragen recognized
rent expense and related charges of $298,000, $290,000 and $47,000 for its
Plantation, Florida property lease and $195,000, $202,000 and $29,000
attributable to its Edinburgh, Scotland facility. Future minimum lease payments
on the two facilities are: 2000 -- $300,912; 2001 -- $307,255; 2002 -- $224,019;
and 2003 -- $200,913; and 2004 and thereafter -- $817,339.

     Viragen has entered into employment agreements with its officers and key
employees. These agreements represent a commitment to pay an aggregate amount of
approximately $1,200,000, per year in salaries to these individuals.

NOTE N -- CONTINGENCIES

     In May 1997, Viragen in the name of Viragen (Europe) (formerly Sector
Associates, Ltd.) was named as a defendant in an action brought in the United
States Bankruptcy Court, Southern District of Florida by the bankruptcy trustee.
The suit alleged that during the period from December 1993 to May 1994, prior to
Viragen's reverse acquisition of Sector, Sector received preferential transfers
of approximately $2.1 million. The suit was settled on July 8, 1998 for a total
of $25,000. The loss arising from settlement of the suit was recognized during
fiscal 1998.

     In October 1997, Viragen, the company's president, and Cytoferon Corp., a
former affiliate of Viragen's president, were named as defendants in a civil
action brought in the United States District Court for the Southern District of
Florida (Case No: 97-3187-CIV-MARCUS) by a Viragen shareholder and investor in
Cytoferon Corp. The suit alleged the defendants violated federal and state
securities laws, federal and state RICO statutes, fraud, conspiracy, breach of
fiduciary duties and breach of contract. The plaintiff was seeking an
unspecified monetary judgement and the specific performance delivery of 441,368
shares of common stock. Viragen filed a motion to dismiss denying the
allegations and requesting reimbursement of its costs.

     In November 1997, the plaintiff in this litigation filed a notice of
voluntary dismissal with the federal court concurrently notifying Viragen of his
intent to refile a complaint in circuit court in the state of Florida. The
plaintiff subsequently filed a complaint in the Circuit Court of the 11th
Judicial Circuit in and for Miami-Dade County, Florida (Case No: 97-25587 CA30)
naming the same defendants. The suit alleges breach of contract, fraud,
violation of Florida's RICO statute and breach of fiduciary duties and seeks a
judgement similar to that of the dismissed federal suit.

     In March 1998, the circuit court granted Viragen's motion to dismiss in
this matter. Subsequently, the plaintiff filed an amended complaint alleging
similar claims and seeking a judgement similar to that of the dismissed federal
and initial state of Florida suits. In April 1998, Viragen filed a motion to
dismiss the

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

plaintiff's amended complaint which was denied by the court. Viragen denies the
allegations of the complaint and intends to vigorously defend the claims with
regard to this matter. The ultimate liability, if any, cannot be determined at
this time and no accrual for loss has been recorded.

     In September 1999, the federal court recommended that Viragen receive
reimbursement for attorney's fees and expenses incurred in the federal suit
described above. Management has filed an objection claiming that the award does
not adequately cover the fees and expenses incurred defending the suit. A final
decision is pending.

NOTE O -- GEOGRAPHIC INFORMATION

     In 1997, Viragen completed a manufacturing facility in Edinburgh, Scotland.
Identifiable assets in Scotland totaled $4,506,000 and $4,745,000 at June 30,
1999 and 1998, respectively. Identifiable assets represent those assets used in
the operations of the geographic area.

NOTE P -- SUBSEQUENT EVENTS

     On August 10, 1999, Viragen mortgaged its Florida-based research facility
for $600,000. Interest on the promissory note is payable in twelve monthly
installments, commencing on August 10, 1999. Interest is calculated at the rate
of 1% over the prime rate per annum, as quoted by the Wall Street Journal, and
the rate is adjusted on a daily basis. The principal balance of $600,000 plus
any unpaid interest is due on July 10, 2000.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 145 of the General Corporation Law of Delaware allows a
corporation to indemnify any person who was or is, or is threatened to be made a
party to any threatened, pending, or completed suit or proceeding. This applies
whether the matter is civil, criminal, administrative or investigative because
he or she is or was a director, officer, employee or agent of the corporation.

         A corporation may indemnify against expenses, including attorney's
fees, and, except for an action by or in the name of the corporation, against
judgments, fines and amounts paid in settlement as part of this suit or
proceeding. This applies only if the person indemnified acted in good faith and
in a manner he or she reasonably believed to be in the best interest of the
corporation. In addition, with respect to any criminal action or proceeding, the
person had no reasonable cause to believe his or her conduct was unlawful.

         In the case of an action by or in the name of the corporation, no
indemnification of expenses may be made for any claim, as to which the person
has been found to be liable to the corporation. The exception is if the court in
which this action was brought determines that the person is reasonably entitled
to indemnity for expenses.

         Section 145 of the General Corporation Law of Delaware further provides
that if a director, officer, employee or agent of the corporation has been
successful in the defense of any suit, claim



                                      II-1


<PAGE>   88


or proceeding described above, he or she will be indemnified for expenses,
including attorney's fees, actually and reasonably incurred by him or her.

         Indemnification for liabilities arising under the Securities Act of
1933, as amended, is permitted as to directors, officers and controlling persons
of Viragen, in the opinion of the Securities and Exchange Commission,
indemnification is against public policy and is, therefore, unenforceable. In
the event that a claim for indemnification against these liabilities, other than
the payment by Viragen in the successful defense of any action, suit or
proceeding, is asserted, Viragen 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 indemnification by it is against
public policy. Viragen will be governed by the final adjudication of this issue.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

         In December 1996, Viragen issued 5,000 shares of its series C
convertible preferred stock to three accredited investors for a cash
consideration of $5,000,000. The issuance was effected pursuant to Rule 506

Section 3(9) of the Securities Act of 1933.

         In June 1997, Viragen issued 138,223 common shares from treasury, in

approximately $288,000 and were issued pursuant to Rule 506 under Section 4(2)
of the Securities Act of 1933.

         During February 1998 and April 1998, Viragen issued 500 shares of its
series H convertible preferred stock for an aggregate consideration of
$5,000,000 and 200 shares of its series I preferred stock, respectively, to five
accredited investors for an aggregate consideration of $2,000,000. The
transaction was completed pursuant to Rule 506 under Section 4(2) of the
Securities Act of 1933. In connection with the issuance of the securities, we
issued to the holders of the series H and series I preferred stock, warrants to
purchase a total of 1,844,336 shares of common stock of Viragen. In addition,
warrants to purchase 402,052 shares of common stock of Viragen were issued to a
finder for the transaction.

         In March 1999, Viragen issued convertible promissory notes in the
aggregate principal amount of $2,000,000 to two accredited investors. In June
1999, Viragen modified the terms of





                                      II-2
<PAGE>   89

conversion of the promissory notes. Viragen also issued to these investors
warrants to purchase 932,039 shares of common stock of the Company. The
transaction was effected pursuant to Rule 506 under Section 4(2) of the
Securities Act of 1933. Viragen also issued warrants to purchase 155,339 shares
of its common stock to certain finders in the transaction.

         In April 1999, Viragen issued 25,000 common shares as compensation for
services performed by a consultant. The shares had a value of $12,500 and were
issued pursuant to Rule 506 under Section 4(2) of the Securities Act of 1933.

         In May 1999, Viragen issued 2,750,000 shares of its common stock to
three accredited investors for an aggregate consideration of $1,375,000. Each of
the investors was highly sophisticated, had significant financial resources, had
pre-existing relationships with Viragen and was provided with access to relevant
information relating to Viragen. The transaction was effected in accordance with
Section 4(2) of the Securities Act of 1933.

ITEM 17. UNDERTAKINGS

         The undersigned registrant hereby undertakes:

         (a) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
Viragen has been advised that in the opinion of the Securities and Exchange
Commission indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable. In the event that a
claim for indemnification against liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of Viragen in the successful defense of any action, suit or proceeding)
is asserted by a director, officer or controlling person in connection with the
securities being registered, Viragen 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 of whether indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of this issue.

         (b) That for the purposes of determining any liability under the
Securities Act, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of these securities at that time will be
deemed to be the initial bona fide offering thereof.

                                       I.
                              PRELIMINARY STATEMENT

 In medical practice, whole blood preserves are being used less and less.
 Instead, blood components are more frequently being fractionally distilled into
 blood plasma and erythrocytes depending on the medical indices. During this
 first phase of fractionation (centrifugation), a layer is created alongside the
 blood plasma and erythrocytes, the so called 'buffycoats", that contains
 various cells: the different types of leukocytes which, for medical reasons,
 must be strictly separated from the erythrocytes. An alternative method for
 separating the leukocytes is filtration. When whole blood is filtered the
 leukocytes remain in the filter. Unlike blood plasma and erythrocytes,
 leukocytes may not be used directly for medical purposes. Certain leukocytes
 contained in the buffycoats (source leukocytes) produce different interferon.

 Viragen bas developed a medical product. Omniferon(TM), the production of which
 requires substantial quantities of source leukocytes, Since source leukocytes
 cannot be stored for longer periods of time, the processing must take place in
 the Federal Republic of Germany. Viragen intends to establish the processing
 facilities through a subsidiary ("VGer") in Germany.

 Omniferon has not yet been approved as a drug.

 Thus the use of source leukocytes lies in Viragen's interest because the source
 leukocytes is the originating material for the production of Omniferon. A
 prerequisite for VGer in establishing processing facilities in Germany is that
 a sufficient quantity of source leukocytes be yielded and available.

 The DRK-BSD's interest in this matter lies in putting to further, medically
 meaningful use the source leukocytes which are automatically yielded during the
 first fractionation of the valuable basic blood plasma (Guts Blut)

 Based on the foregoing reasons. Viragen. VGer and DRK-Blutspendedicnstc are
 interested in working together as partners.
 Wherefore, the parties agree as follows:

                                       II.

                        COOPERATION AND SUPPLY AGREEMENT

                                      SS. 1
                         SUBJECT MATTER OF THE AGREEMENT

 (1)     The subject matter of this Agreement is the collaboration of the
         Contracting Parties to use DRK source leukocytes in the manufacture of
         biological medical products.

 (2)     In furtherance hereof, DRK-BSD shall, on a preferential basis, supply
         to VGer source leukocytes which have been produced from whole blood
         preserves and which were examined in accordance with the applicable
         statutory and regulatory provisions (Appendix 1) under the laws of the
         Federal Republic of Germany. Such source leukocytes will be supplied
         for purposes of producing and Interferon compound. Delivery shall be
         made in the form of buffycoats containing source leukocytes. DRK-BSD
         shall not conduct a prior second fractionation of the buffycoats. The
         buffycoats are not a finished pharmaceutical product, but rather a
         by-product.

 (3)     VGer agrees to derive the source leukocytes from the raw material
         supplied (buffycoats or filter). If new production methods are
         employed, then the agreements memorialized in this contract will
<PAGE>   3
         apply to the separated leukocytes only. If necessary, VGer will be
         responsible for yielding the leukocytes.

 (4)     The DRK-BSD agree at their own expense to adjust their production
         conditions to the extent required in order to comply with the approval
         requirements for the other compounds created from the whole blood. The
         DRK-BSD further agree to adapt their production conditions to VGer's
         production conditions and specifications if this is possible as part of
         the approval process for the other compounds extracted from while blood
         and provided that VGer expresses its willingness to assume the
         additional expenses resulting therefrom. The quality features of the
         buffycoats as well as the requirements of production, transport and
         specifications which must be observed in any given case are set forth
         in detail in Annex 2 to this Agreement. The DRK-BSD shall bear all
         costs arising from the production of raw material in this respect.


                                      SS. 2
                     DELIVERY, ANNUAL SCHEDULING, ACCEPTANCE

 (1)     The DRK-BSD agree to deliver the quantity of source leukocytes required
         by VGer for operating and fully utilizing a production facility
        (1 million buffycoats annually)

 (2)     VGer agrees to accept for the upcoming year the buffycoats that have
         been ordered by 30 September of a current year. The deliveries will be
         ordered on a quarterly basis with a margin of fluctuation of plus or
         minus 15%. Such margin of fluctuation will be based on one-fourth of
         the annual amount ordered. VGer shall project the estimated annual
         quantity each calendar year and notify the DRK-BSD thereof.

 (3)     VGer is free to determine the annual order quantity (preferential
         deliveries) during a transitional two-year period beginning with the
         acceptance of deliveries. After such two-year period, the annual order
         quantity shall be one million buffycoats, plus or minus 15%.

 (4)     The order must be in writing and shall be submitted to a contact
         person as defined in SS.15.


 (5)     Each of the DRK-BSD agrees, under this Agreement and up to their
         respective capacity limit, to supply a proportional quantity of
         buffycoats or source leukocytes corresponding to its respective
         donations in the previous year. VGcr shall be informed of such in
         writing no later than 31 January of the following calendar year. The
         delivery of small quantities shall be carried out by internal
         arrangement of the DRK-BSD through individual DRK-BSD.

         The time-table for on-going deliveries by the individual DRK.BSD shall
         be mutually stipulated by all the parties from time to time during the
         term of the Agreement.

         If one DRK-BSD cannot fulfill this obligation, in whole or in part, the
         other DRK-BSD agree to supply, within the scope of this Agreement and
         their respective capacity limits, the deficient quantity. The delivery
         shall be arranged internally by the DRK-BSD in accordance with sentence
         3 of SS.2(5). This also applies to the mutual duty to inform and any
         agreements among the DRK-BSD regarding internal financial settlement
         arrangements. In the event of a non-culpable interruption in business
         operations, the DRK-BSD that are privy to this Agreement may discharge
         their delivery obligations by also supplying VGer with source
         leukocytes which are obtained from other DRK-BSD and which meet the
         quality requirements under this Agreement.

<PAGE>   4
( )      VGer may export any buffycoats supplied by the DRK-BSD to other
         production facilities within the Viragen group of affiliated companies.
         VGer shall obtain the necessary governmental permits and approvals.

( )      VGer shall notify the DRK-BSD six months prior to the date on which the
         DRK-BSD should initiate regular deliveries (following the approval of
         Omniferon) as part of the production procedure. Once the deliveries
         have commenced, the DRK-BSD are obliged to initially supply half of the
         contractually stipulated quantity for a period of six months.

                                      SS.3
                                  DISTRIBUTION

(1)      Pursuant to a special agreement yet to be concluded. VGer shall grant
         DRK-BSD the right to use Omniferon - a substance produced from the
         source leukocytes supplied by the DRK-BSD - at the institutions which
         are listed in Annex 3 and in which the associations of the German Red
         Cross have a majority interest or which are operated by one or more
         associations of the German Red Cross at wholesale prices which VGer
         changes from time to time in Germany and which are otherwise based on
         terms which have yet to be mutually stipulated. The Contracting Parties
         shall use their best efforts to negotiate a definitive sales agreement
         as soon as all documents necessary for approval (product license
         application) have been submitted to the competent authorities.

(2)      VGer further agrees that, to the extent commercially reasonable, the
         Federal Republic of Germany will receive priority distribution of the
         Omniferon made from the source leukocytes supplied by the DRK-BSD after
         it has been approved in there.

                                      SS.4
                    COMPENSATION, PAYMENT DATES, CONFIRMATION

(1)      The compensation for the source leukocytes supplied by the DRK-BSD
         shall be (*) of the consolidated sales of Omniferon as
         achieved by the Viragen group affiliated companies (Viragen, Inc. and
         all subsidiaries in which Viragen, Inc. is a majority owner). The basis
         for this calculation will not be the actual realized sale price, but
         rather the final sales price to consumers (without turnover tax) as
         shown in the so-called "Red List". The lowest sales price shall be DEM
         (*)/buffycoat plus turnover tax and the highest sales price shall be
         DEM (*)/buffycoat plus turnover tax. If no end sale price is indicated
         on the Red List, then the sales price will be the lowest sales price
         per buffycoat. Section 12(4) governs adjustments to the lowest and
         highest sale price.

(2)      Compensation is due each year after the annual Viragen group
         financial statements have been reviewed. Installment payments toward
         the compensation must be made for the supplied buffycoats based on the
         lowest purchase price. The installment payments are due 90 days after
         delivery is made. Upon demand by DRK-BSD, Viragen or VGer shall furnish
         a bank guaranty (Bankburgschaft) in the amount if DEM (*) million to
         cover the amounts outstanding.

(3)      The DRK-BSD have the right to obtain from the Viragen group financial
         statement auditor  a certification as to the relevant annual sales of
         the Omniferon which is the subject matter of this Agreement. The
         certification shall be sent to DRK-BSD within 30 days after the
         auditor has presented this audited Viragen annual financial statements.

(4)      If turnover tax is due on services performed under this Agreement, then
         such taxes shall be paid by the recipient of the services. The DRK-BSD
         agree to clarify the turnover tax treatment of the services.

(5)      To discharge the obligation owed, payments must be made to a bank
         account specified in the future.

 (6)     Claims arising from this Agreement may not be assigned.



                                      SS.5
                       PLACE OF PERFORMANCE, RISK OF LOSS

 (1)     With respect to any processing in Germany, the place of performance is
         the VGer production facility. With respect to any processing abroad,
         the place of performance is the airport in Germany which VGer has
         designated to the DRK-BSD as the place of delivery.

 (2)     The DRK-BSD bears the risk of loss for the accidental destruction or
         accidental deterioration of the buffycoats during their transport to
         the place of performance.

                                      SS.7
            COMPENSATORY DAMAGES, WARRANTY, DUTIES OF CARE, INSURANCE

 (1)     DRK-BSD's liability for product defects and consequential damages due
         to product defects is expressly limited to cases where the defect is
         the result of fault and the causality of the damage has been proven.
         The fault of the DRK-BSD vicarious agents will be imputed to the
         DRK-BSD. If the fact surrounding the faulty act occurred within the
         DRK-BSD sphere of risk, then DRK-BSD shall have the burden to prove
         that it was not at fault. Where fault exists, DRK-BSD will be liable
         for all damages including any pecuniary harm arising when products
         produced by Viragen or one of its affiliated companies cannot be sold
         or can be sold only at a reduced price. The total liability for all
         parties is limited to a maximum of DEM 2 million annually. The DRK-BSD
         are also obligated to replace all original material they had delivered
         in the event damages arose as a result of their fault.

         In all other cases, DRK-BSD's liability shall be governed by statute or
         the legal principles developed by case law. Liability will attach only
         if the relevant Contracting Parties are responsible for the
         circumstances upon which the liability is based. Compensatory damage
         claims for VGer's lost profits based on the non-performance of the
         delivery obligation under SS.2(5) are precluded.

 (2)     The Contracting Parties are aware that not all rare infectious diseases
         (e.g., Creutzfeldt-Jacob Syndrome) can be identified under today's
         current testing procedures. The legal reporting requirements which are
         partially in place today may in some cases lead to a recall actions
         many years down the road. The DRK-BSD agree to promptly inform Viragen
         and VGer in the event that recall action criteria arise. The
         Contracting Parties hereby establish that henceforth in such cases the
         DRK-BSD shall replace free of charge the delivered source material
         produced from a contaminated production batch. Any additional losses
         shall be borne by each Contracting Party individually.

 (3)     The DRK-BSD also otherwise agree to recall promptly any buffycoats
         which fail to meet the requirements set forth in SS.1(4). The DRK-BSD
         agree to comply with all statutory and regulatory provisions together
         with the requirements implicit therein as prescribed under the laws of
         the European Union and Germany and applicable to the production and
         introduction into commerce of source leukocytes (see also SS.1(4). The
         current quality requirements for the buffycoats, the production
         conditions, and the specifications are reproduced in Annex 2 to this
         Agreement.

 (4)     The DRK-BSD agree to obtain a general liability insurance policy for a
         reasonable amount with a reputable insurance company, to maintain such
         policy for the duration of the Agreement, and to furnish proof thereof
         to VGer. The current insurance policies are listed in Annex 4 of this
         Agreement.

                                      SS.7
                      PARTICIPATION IN APPROVAL PROCEEDINGS

At the request of the DRK-BSD, the clinics (German Red Cross member associations
or a companies of which a German Red Cross member association holds a majority
interest) listed in Annex 5 of this Agreement may be included in the
implementation of clinical studies within the scope of the approval proceedings
if these clinics fulfill the clinical and technical requirements for such and
also have the requisite licenses.

                                      SS.8
                       TERM OF THE AGREEMENT, TERMINATION

(1)      The Agreement shall enter into force on 1 July 1998 for an initial
         definite term of ten years. The Agreement shall be automatically
         extended for an additional year in the event that a termination notice
         has not been given twelve months before the expiration of the Agreement
         or the expiration of any extension of the Agreement.

(2)      A party to the Agreement may, without notice, prematurely terminate the
         Agreement for cause if the terminating party is not responsible for the
         facts or circumstances underlying the cause for termination. Cause will
         be deemed to exist if:

         -        Viragen, VGer or a subsidiary has not submitted all documents
                  necessary for the approval of Omniferon (Product License
                  Application) in a European Union (EU) member state by 1 July
                  2003;

         -        a party to the Agreement materially breaches Red Cross Policy,
                  printed in Annex 6 of this Agreement, and the breach is not
                  remedied within 30 days despite a written demand to do so;

         -        circumstances arise for a party to the Agreement (particularly
                  through sovereign acts) that make impossible, materially
                  disrupt, prejudice, or make unreasonable the continuation of
                  the Agreement, or it is no longer technically feasible and
                  commercially practicable for Viragen to extract source
                  leukocytes from the supplied raw material;

         -        a party to the Agreement ceases making payments; files for
                  bankruptcy, a judicial composition among creditors or a

 facts concerning its enterprise. Subject to the prior consent of the other
 Contracting Parties in accordance with SS.10, all Contracting Parties are
 entitled to publish details concerning the cooperation between the Contracting

                          ADJUSTMENTS TO THE AGREEMENT

 (1)     If, as a result of medical/technical developments and/or statutory or
         regulatory requirements, changes arise which will negatively impact
         costs and/or prices, then the Contracting Parties shall, using their
         best efforts, conduct negotiations concerning adjustments to the
         Agreement.

 (2)     Sub-section 1 shall also apply in the event of significant changes in
         the cost structure connection with the creation of source leukocytes
         and/or the production of Omniferons and the availability of source
         leukocytes in quantities and forms (buffycoat/filter) and in the event
         of a significant drop in donations. This will apply accordingly in the
         event that VGer manufactures additional products from the raw materials
         supplied.

 (3)     The Contracting Parties mutually agree, to the extent it is reasonable,
         to eliminate or reduce any detrimental changes from the current
         conditions and to use any possible improvements.

 (4)     The following applies with respect to any adjustments to the minimum
         and maximum per buffycoat purchase price as provided in SS.4(1). If the

         employees with higher incomes as established by the Federal Office of
         Statistics in Wiesbaden increases and decreases from the status per
         January 2000, then the minimum or maximum purchase price will be
         adjusted accordingly. The adjustment will be conducted annually at the
         beginning of any given calendar month commencing with deliveries were
         made prior thereto. Regarding the price quote, the date on which
         delivery is made to the DRK-Blutspendedienst will be dispositive.
         Should the above-referenced cost of living index

         replaces it or the one which is most similar to it will be deemed as
         the controlling index for purposes of this provision.

MENSCHLICHKEIT

Die Internationale Rotkreuz- und Rothalbmondbewegung, entstanden aus dem Willen,
den Verwundeten der Schlachtfelder unterschiedslos Hilfe zu leisten, bemuht sich
in ihrer nationalen und internationalen Tatigkeit, menschliches Leiden uberall
und jederzeit zu verhuten und zu lindern. Sie ist bestrebt, Leben und Gesundheit
zu schutzen und der Wurde des Menschen Achtung zu verschaffen. Sie fordert
gegenseitiges Verstandnis, Freundschaft, Zusammenarbeit und einen dauerhaften
Frieden unter den Volkern.

UNPARTEILICHKEIT

Die Rotkreuz- und Rothalbmondbewegung unterscheidet nicht nach Nationalitat,
Rasse, Religion, sozialer Stellung oder politischer Uberzeugung. Sie ist einzig

dringendsten FallenVorrang zu geben.

Um sich das Vertrauen aller zu bewahren, enthalt sich die Rotkreuz- und
Rothalbmondbewegung der Teilnahme an Feindseligkeiten wie auch, zu jeder Zeit,
an politischen, rassischen, religiosen oder ideologischen Auseinandersetzungen.

UNABHANGIGKEIT

Die Rotkreuz- und Rothalbmondbewegung ist unabhangig. Wenn auch die Nationalen
Gesellschaften den Behorden bei ihrer humanitaren Tatigkeit als
Hilfsgesellschaften zur Seite stehen und den jeweiligen Landesgesetzen
unterworfen sind, mussen sie dennoch eine Eigenstandigkeit bewahren, die ihnen
gestattet, jederzeit nach den Grundsatzen der Rotkreuz- und Rothalbmondbewegung
zu handeln.



<PAGE>   21

FREIWILLIGKEIT

Die Rotkreuz- und Rothalbmondbewegung verkorpert freiwillige und uneigennutzige
Hilfe ohne jedes Gewinnstreben.

EINHEIT

In jedem Land kann es nur eine einzige Nationale Rotkreuz- oder
Rothalbmondgesellschaft geben. Sie muB allen offenstehen und ihre
humanitare Tatigkeit im ganzen Gebiet ausuben.

UNIVERSALITAT

Die Rotkreuz- und Rothalbmondbewegung ist weltumfassend. In ihr haben alle
Nationalen Gesellschaften gleiche Rechte und die Pflicht, einander zu helfen.

                                 Exhibit 10(lix)

   Buffycoat Supply Agreement between America's Blood Centers and the Company
                              dated July 15, 1998




<PAGE>   2

                                   AGREEMENT

This agreement ("Agreement") is made and entered into this 15th day of July,
1998 by and between America's Blood Centers ("ABC"), an Arizona non-profit
corporation with its principal office at 725 15th St., N.W., Suite 700,
Washington, DC 20005, and Viragen, Inc. ("Viragen"), a Delaware corporation,
and Viragen, U.S.A., Inc. ("VUSA"), a Delaware corporation and a wholly-owned
subsidiary of Viragen, both having their principal offices at 865 SW 78th Ave.,
Suite 100, Plantation, FL 33324.

                                    RECITALS

The parties recognize that the U.S. blood supply is a vital resource of which
the non-profit independent blood centers who are members of ABC ("IBCs") are
partially entrusted and that the IBCs have a charitable mission to serve the
communities in which they operate and collect blood.

ABC and the IBCs have indicated that most Buffycoats (defined herein)
harvestable by the IBCs from whole blood or blood component collections
currently are not separated from the IBCs' core component products, and,
therefore, are generally considered an underutilized byproduct.

It is VUSA's intention, directly or indirectly, to conduct manufacturing and
clinical operations and to seek FDA approval to market its products for the
treatment of one or more medical conditions. In addition, it is VUSA's
intention, subject to approval by its Board of Directors, to eventually list
its shares of common stock either on the OTC bulletin board or, upon
qualifying, on NASDAQ.

ABC has agreed to collaborate with Viragen and VUSA to put Buffycoats to
humanitarian use by establishing a program under which IBCs that are members of
ABC may supply Buffycoats to VUSA on a preferential basis for manufacture into
certain products by or on behalf of VUSA (and its Affiliates and sublicensees)
including the manufacture of Omniferon(TM), Viragen's second-generation natural
human alpha interferon product. Omniferon is being developed for use in the
potential treatment of various life threatening and debilitating diseases,
including HIV/AIDS, hepatitis B & C, multiple sclerosis and cancer.

                                  DEFINITIONS

the number of Buffycoats (i) that are actually manufactured by a PIBC in the
prior forecast period, or (ii) that could be reasonably manufactured by a PIBC
during that current forecast period through the exercise of good faith
commercial diligence, taking into account source material supply and good
manufacturing practices. The Available Supply shall be determined before any
reductions of inventory for obligations to any Person other than VUSA;
provided, that human source leukocytes retained under Section 2.4 herein shall
be excluded from Available Supply.

"Buffycoat(s)" shall mean individual shipping units of packaged human source
leukocytes produced by ABC members from whole blood unit collections, or from
other means, including filtration and pheresis.

"Buffycoat Capacity" shall mean the total number of whole blood units that are
or reasonably could be drawn, processed or otherwise obtained by all PIBC
establishments, including the Buffycoat Facilities.

                                   COVENANTS

1.       ABC LOGISTICS OBLIGATIONS.

1.1 Recruiting PIBCs. ABC shall use its best efforts during the term of the
Agreement to recruit and cause the maximum number of IBCs to become PIBCs.

1.2 Acceptance of PIBCs. VUSA shall accept and enter into a Subagreement with
any IBC recruited by ABC, provided that the PIBC (a) meets all FDA and other
federal, state and local government regulatory requirements to be a supplier of
Buffycoats to VUSA, (b) is not under a notice of intent to revoke or has
received notice of intent to revoke its FDA authority to be a supplier of
Buffycoats, and (c) demonstrates its ability, to VUSA's reasonable
satisfaction, to meet the Specifications; and (d) is willing and able to enter
into and perform its obligations under the Subagreement. VUSA shall not be
obligated to enter into a Subagreement with any PIBC that is subject to
threatened with material and unresolved adverse regulatory findings or actions
by FDA or other authority, or that is under or threatened with insolvency or
bankruptcy or other adverse actions of its creditors.

1.3 Coordination of Production and Delivery of Buffycoats. ABC will perform
logistical and other services ("Services") under this Agreement, particularly,
acting as an interface between VUSA and the PIBCs. ABC's Services shall
include, but not be limited to, preparation and coordination of supply
forecasts, purchase orders and shipments, billings and payments,
communications, accounting and financial audits, document retention, and
allocation of VUSA purchase orders among PIBCs. No later than 10 days before
the commencement of a calendar quarter, ABC will advise VUSA of the PIBCs that
are expected to be fulfilling that quarter's purchase order for Buffycoats and
the estimated number of Buffycoats that will be shipped by each PIBC. VUSA,
ABC, and the PIBCs will cooperate to ensure that the Buffycoats purchased and
sold by PIBCs are shipped in an orderly manner so as to allow both VUSA and the
PIBCs to conduct their operations in the most efficient manner. In determining
which PIBCs will fulfill a particular purchase order, ABC intends not to
discriminate among PIBCs; provided, however, that ABC shall use its good faith
best efforts to coordinate shipments to minimize the number of PIBCs shipping
Buffycoats to a particular VUSA facility at or about the same time and the
transportation costs incurred (e.g., freight and insurance). ABC shall (i) give
VUSA timely notice if a PIBC that was to deliver Buffycoats to VUSA is unable
to fulfill such order, and (ii) use its best efforts to promptly fulfill the
undelivered portion of that order from another PIBC.

1.4 Compensation of ABC for Logistical and Other Services. As compensation for
ABC's Services, at the end of each calendar quarter, VUSA shall pay ABC the
following: (a) reimbursement of the actual, incremental costs of these Services
during the prior quarter, including but not limited to personnel costs,
long-distance telephone costs, and facsimile and express mailing costs
(provided they do not exceed the budget by more than 10%); and (b) a
reimbursement of $0.10 for each Buffycoat supplied under the





                                       3
<PAGE>   5

Agreement during the prior quarter (to cover costs previously incurred). The
$0.10 per Buffycoat reimbursement under "1.4(b)" will continue only until the
sum of $25,000 has been paid under 1.4(b). ABC shall provide advance annual
budgets to VUSA (with quarterly reviews) for the Services anticipated, and VUSA
shall have the right in advance to decline Services that it does not wish ABC
to perform. Payments to ABC under this paragraph shall be made within 30 days
of the end of the quarter or within 30 days of receiving ABC's invoice,
whichever is later.

2.       BUFFYCOAT SUPPLY.

2.1 First and Preferential Access. During the term of the Agreement, and
subject to the provisions of 2.4, VUSA shall have First And Preferential Access
to all Buffycoats harvestable by each PIBC from its blood or blood component
collections (including from filtration) to meet VUSA's clinical, research and
development, and commercial production needs. "First And Preferential Access"
means the following: (a) ABC and/or each PIBC shall not enter into any contract
or arrangement that conflicts with or negates the PIBCs ability during the term
of the Agreement to fulfill a potential VUSA purchase order for Buffycoats; and
(b) each PIBC shall give priority to fulfillment of VUSA's existing orders for
Buffycoats.

2.2 Use of Buffycoats. VUSA shall not be restricted in the use of Buffycoats
obtained from the PIBCs, provided, however, Buffycoats may not be resold by
VUSA (except to Viragen or a VUSA or Viragen Affiliate for use by Viragen or
such Affiliate and not further re-sale as unprocessed Buffycoats).

2.3 Harvesting of Buffycoats. Each PIBC agrees to harvest and deliver the
Buffycoats in accordance with FDA requirements and guidelines, including
applicable Good Manufacturing Practices ("GMP"), and the Specifications.

2.4 Exceptions to First and Preferential Access. VUSA's First And Preferential
Access shall be subject to the right of each PIBC during the term of the
Agreement (a) to retain human source leukocytes to supply hospitals solely for
the purpose of direct transfusions for patient treatment and (b) to meet the
preexisting contractual obligations set forth as an Exhibit to each PIBC
Subagreement. Each PIBC agrees not to expand any of the obligations set forth
in third party agreements listed in such Exhibit (unless such third party
agreement requires such expansion). Unless otherwise prohibited from doing so,
each PIBC agrees to provide VUSA, for informational purposes, with historical
and current data on Buffycoats supplied for the purpose of direct transfusions
in patient treatment and pursuant to pre-existing contractual obligations.

2.5 Supply of Buffycoats to Other Parties. Each PIBC shall have the right to
supply other parties with Buffycoats provided that such supply does not
interfere with VUSA's First And Preferential Access.

2.6 Buffycoat Production from Pheresis Collections. Each PIBC shall use its
best efforts to undertake to supplement Buffycoat production with Buffycoats
from pheresis collections, if requested by VUSA and subject to the PIBCs
reasonable consent, provided, however, there are no regulatory impediments or
material negative consequences to the production of other blood components or
other aspects of the PIBCs operations.

2.7 Buffycoat Testing. The PIBC shall conduct transmissible disease testing on
all Buffycoats, and source materials, in accordance with FDA and other federal,
state and local requirements, guidelines and recommendations.

2.8 Non-compete. During the term of this Agreement and for one year thereafter
(and in the case of termination by VUSA or Viragen on account of a material
breach by ABC or any PIBC for no less than the expected initial term of this
Agreement, or if the initial term has expired, for three years from the date of
termination), neither ABC nor any PIBC shall engage directly, or indirectly, in
the research, development, production or commercialization of any Buffycoat or
white blood cell-derived product or interferon





                                       4
<PAGE>   6

products or derivatives, or methods of making or using same; provided, however,
that nothing herein shall prohibit ABC or any PIBC from reselling an interferon
product.

2.9 Sublicense. VUSA shall grant a sublicense to each PIBC, at no cost, to use
VUSA's Specifications for the purposes of performing this Agreement and the
Subagreements.

2.10 Obtaining Buffycoats from Other Parties. Subject to the other terms and
conditions of the Agreement, Viragen, VUSA and/or Affiliates may obtain
Buffycoats from other parties, provided, however, that (i) Viragen, VUSA and/or
their Affiliates may not give priority or preference in ordering to any other
U.S. source of Buffycoats, (ii) VUSA may not give priority or preference in
ordering to any other source of Buffycoats, and (iii) during the first 24
months after the Effective Date, Viragen, VUSA and Affiliates agree that at
least *_________ of Buffycoats utilized by them in the United States shall be
ordered from PIBCs pursuant to this Agreement.

2.11 MFN for Purchases from ABC Members. Viragen and/or its Affiliates will not
obtain Buffycoats from any ABC member for greater aggregate compensation per
Buffycoat than is provided in this Agreement (taking into account all forms of
compensation to be received by the PIBCs).

2.12 No MFN for U.S. Source Buffycoats Given to a Non-ABC Member. Viragen and
VUSA represent and covenant that they have not given and will not give a "most
favored nation clause" for U.S. source Buffycoats to any non-ABC member.

2.13 Training and Education. VUSA shall provide reasonable and necessary
training and education on the Specifications at VUSA's expense to each PIBC,
including on-site training at VUSA's expense where reasonably necessary. Such
training and education shall be provided before the PIBC harvests Buffycoats
under this Agreement, and thereafter as reasonably required on an as needed
basis.

3.       FORECASTS AND ORDERS.

3.1 Rolling Forecasts. VUSA shall provide ABC with rolling quarterly forecasts
of VUSA's Buffycoat requirements ("Rolling Requirements Forecast") from the
PIBCs for the three calendar quarters that follow the next immediate calendar
quarter. Such Rolling Requirements Forecasts shall be provided 30 days before
the start of the next immediate calendar quarter, for the term of the
Agreement. (Example: on or before February 28, 1999, VUSA shall provide ABC
with forecasts of its Buffycoat requirements for July-September 1999,
October-December 1999, and January-March 2000.)

3.2 Purchase Orders. Along with the Rolling Requirements Forecast, VUSA shall
submit a purchase order for the quantity of Buffycoats to be supplied by the
PIBCs during the next immediate calendar quarter. (Example: on or before
February 28, 1999, VUSA shall provide ABC with a purchase order for Buffycoats
for April-June 1999.). The parties agree that prior to the date an NDA for
Omniferon becomes approved by FDA they will negotiate in good faith to reach an
agreement on minimum Buffycoat purchase commitment by VUSA during the period of
Omniferon Commercialization, which minimum purchase commitment shall be
consistent with Sections 2.10(i) and 2.10(ii).

3.3 ABC/PIBC Forecasts. Upon the Effective Date and thereafter during the Term,
at least thirty (30) days before the start of the each subsequent calendar
quarter, ABC shall provide VUSA with good faith rolling quarterly forecasts of
ABC/PIBCs anticipated Available Supply for each of the subsequent four calendar
quarters (the "Rolling Supply Forecast"). The forecast made in the Rolling
Supply Forecast of anticipated PIBC Available Supply for the calendar quarter
immediately subsequent to the quarter following the date the Rolling Forecast
is provided shall be the "Confirmed Supply Forecast".

3.4 Taking Title to and Payment for Buffycoats. During the term of this
Agreement, VUSA shall be obligated to pay for and take title to and possession
of all acceptable Buffycoats that conform to the






                                       5
<PAGE>   7

Specifications, ordered by VUSA and produced and delivered by each PIBC in
accordance with this Agreement; provided that all such Buffycoats shall be free
of all liens, security interests and third party interests upon delivery.

3.5 Variations Between Forecast and Order. VUSA may order an amount that is no
more than 25% greater or lesser than the applicable Rolling Requirements
Forecast; provided that in no event shall any order exceed, in the aggregate,
the ABC/PIBC Confirmed Supply Forecast.

3.6 Variations Between Forecasts. VUSA may not submit a Rolling Requirements
Forecast that is less than 75% of the last quarterly Rolling Supply Forecast
submitted for that quarter. Additionally, subject to Section 3.7, VUSA may not
submit a Rolling Requirements Forecast that is greater than 125% of the last
quarterly Rolling Requirements Forecast submitted for that quarter. (Example:
When VUSA submits its Rolling Requirements Forecasts on or before February 28,
1999, the Rolling Requirements Forecast for July-September 1999 may not, except
as provided in this Agreement, deviate more than 25% (upward or downward) from
the Rolling Requirements Forecast that was submitted on or before November 30,
1998 for that quarter.)

3.7 Additional Variations. ABC and the PIBCs shall use their best efforts to
fulfill VUSA purchase orders or quarterly forecasts for amounts greater than
permitted in 3.5 and 3.6; provided, however, that nothing in this Agreement
shall prohibit any PIBC from honoring any prior documented agreement with a
third party to sell Buffycoats to such third party that was made prior to a
VUSA forecast for such Buffycoats.

4.       COMPENSATION FOR BUFFYCOATS.

4.1 Cost Reimbursement. VUSA will reimburse each PIBC, through ABC, on a per
Buffycoat basis for all incremental costs, if any, that each PIBC may incur in
producing Buffycoats for VUSA to VUSA Specifications. Incremental costs shall
be defined as conversion of facilities, protocols, and training of personnel,
if necessary, to produce Buffycoats for VUSA, and direct material, labor, and
overhead costs directly attributable to Buffycoat production and supply under
VUSA Specifications; provided, that the maximum budget for each PIBC for all
such incremental costs for that PIBC shall be specifically agreed upon by the
parties in writing before being incurred, and shall not thereafter be exceeded
except with the parties' mutual agreement. Incremental costs shall include the
net value (profit) of any other blood components (e.g., plasma) lost by a PIBC
due to the its production of Buffycoats to the extent that such other blood
component could have been actually sold by such PIBC.

4.2 Interim Cost Reimbursement. The interim cost reimbursement shall be --- per
Buffycoat, excluding ABC's fee as specified in Section 1.4 herein. This
reimbursement rate shall be used for the first twenty-four (24) months from the
Effective Date of the Agreement.

4.3 Independent Audit and Analysis of Buffycoat Production Costs. The parties
agree that, no later than 18 months after the Effective Date, the parties shall
select a mutually agreeable independent, national certified public accounting
firm to conduct a reasonable analysis and audit of incremental Buffycoat
production costs as defined herein in order to derive a per Buffycoat cost to
be used under the Agreement. The evaluation, analysis and audit criteria shall
be specified by mutual agreement of the parties hereto. In the event that the
parties are not then able to resolve any differences as to the appropriate per
Buffycoat cost to be used, the matter shall be arbitrated in accordance with
the dispute resolution provisions of this Agreement.

4.4 Transportation Costs. Buffycoats shall be shipped freight and insurance
prepaid FOB VUSA designated location. Incremental transportation costs for
Buffycoats from the PIBCs to VUSA's facilities





                                       6
<PAGE>   8

shall be the responsibility of VUSA, and are not included in the interim cost
reimbursement stated in 4.2. Insurance on each shipment shall be for the
benefit of the PIBC initiating such shipment.

4.5 Royalties on Buffycoats Not Used Commercially. In addition to cost
reimbursements as specified herein, for any Buffycoats that are not used to
produce Omniferon or other products that are ultimately sold Commercially,
directly or indirectly, to a Non-Affiliate Person, each PIBC, through ABC, shall
receive a cash payment for each conforming Buffycoat delivered to VUSA by that
PIBC in the form of a royalty equal to *_____ of the estimated Net Revenues that
VUSA could reasonably have realized from the sale of the marketable Omniferon
that reasonably could have been produced from such Buffycoat, regardless of
whether or not VUSA actually receives any revenues from the sale or use of such
product, or *_____ per Buffycoat, whichever is higher.

4.6 Royalties on Buffycoats Used Commercially. Where conforming PIBC supplied
Buffycoats are used to produce Omniferon that is ultimately sold Commercially,
directly or indirectly, to a Non-Affiliate Person, each PIBC, through ABC, shall
receive *_____ of the actual Net Revenues realized from the sale of Omniferon to
such Non-Affiliate Person, to the extent that such Net Revenues are allocable to
the Buffycoats delivered by each such PIBC, or *_____ per Buffycoat, whichever
is higher.

4.7 Other Product Royalties. Should VUSA develop and manufacture products
derived from the Buffycoats other than Omniferon ("Other Products"), the
royalty rate applicable to such Buffycoats shall be that amount that would be
due had the Buffycoats been used to manufacture Omniferon instead of the Other
Products, taking into account the typical net marketable quantity of Omniferon
then obtained from a Buffycoat (e.g., considering manufacturing yields, cGMP
testing requirements) and net revenues then realized from such Omniferon.

4.8 Time for Payment. Payments for each PIBC for minimum royalties and cost
reimbursements shall be made to ABC no later than 30 days from the date of
acceptance (as specified in Section 5 herein) by VUSA or the date of invoicing,
whichever is later. VUSA shall make any adjustment of the royalty payment (for
royalties due in excess of the minimum) no later than 90 days after the end of
the quarter. VUSA shall pay interest on any wrongfully unpaid amounts at the
rate of 1% per month for each month beyond the due date applicable to such
amounts. All payments shall be itemized by VUSA with regards to basis of the
amount paid (e.g., royalty or reimbursement and the PIBCs and Buffycoat
shipments to which the payment relates).

4.9 Other VUSA Royalty Obligations. ABC and the PIBCs acknowledge that (a) VUSA
is obligated to pay a royalty to Viragen (Scotland) Ltd. of two percent (2%) of
VUSA's net revenues (as such term is defined in the license agreement between
VUSA and Viragen) derived from the sale of Omniferon and (b) VUSA is obligated
to pay a minimum royalty to Viragen of $2,000,000 annually for the exclusive
license in the U.S. to the Specifications and related know-how and the
exclusive manufacturing, marketing and distribution rights for Omniferon in the
U.S., as set forth in the license agreement between VUSA and Viragen, which
royalty payments commence with the date of the first use of the Specifications
and related know-how by or on behalf of VUSA.

4.10 Changes in Specifications or Method of Harvesting Buffycoats. VUSA may
reasonably request that the Specifications be modified or that one or more
PIBCs change their method of harvesting Buffycoats, for example, by employing a
technology upgrade. Any such modifications or changes shall be in writing and
shall require the consent of ABC and the affected PIBCs, which consent shall
not be unreasonably withheld, provided that: (a) reasonable advance notice is
given; (b) VUSA reimburses the PIBC for its non-recurring costs (including
equipment and training costs) of such modification or change; and (c) if the
modification or change results in change in ongoing costs, VUSA and ABC and the
PIBCs shall agree to make a corresponding change in the interim cost
reimbursement (if applicable) or the actual cost reimbursement.

4.11 New Tests or Procedures. In the event that FDA or industry standards
requires the PIBCs to perform new tests or procedures that materially increase
the incremental costs of producing Buffycoats (as defined herein), the parties
shall negotiate an appropriate adjustment of the interim or actual cost
reimbursement to cover such change in costs.

5.       SHIPMENT AND ACCEPTANCE OF BUFFYCOATS.

5.1 Shipment of Buffycoats. Buffycoats shall be shipped at VUSA's expense from
the PIBC to VUSA's designated sites in such manner as VUSA and ABC shall agree
upon in writing, and in accordance with the Specifications.

5.2 Certificate. VUSA shall not be required to accept Buffycoats shipped by a
PIBC unless and until VUSA receives a certificate of analysis that sets forth
all test results for each such shipment and certifies that the shipment of
Buffycoats conforms with the Specifications, and the date and time when and the
location where such blood unit used to manufacture the Buffycoat was drawn from
a blood donor, and each PIBC shall provide such certificate of analysis with
each shipment of Buffycoats.

5.3 Rejection of Buffycoats. No later than five (5) business days after VUSA
receives the certificate of analysis described in 5.2, VUSA may reject any
Buffycoats that (i) do not conform to the Specifications, or (ii) that were not
manufactured in accordance with this Agreement, or (iii) that are otherwise
reasonably determined not to be suitable for use in the manufacture of
parenteral human therapeutic products, (including, but not limited to, such
Buffycoats failing VUSA acceptance testing). Additionally, VUSA may revoke
acceptances because of any event in categories (i), (ii) or (iii) above that
could not reasonably have been known at the time of acceptance, including, but
not limited its reliance on an inaccurate certificate of analysis, or later
discovery of adverse findings of regulatory compliance and quality assurance
audits or inspections of Buffycoat Facilities by VUSA or government agencies.
VUSA shall promptly notify ABC and the PIBC supplying shipments VUSA intends to
reject or revoke the acceptance of and the reasons for such rejection or
revocation.

5.4 Recalls by PIBC. Each PIBC shall immediately notify VUSA of any information
regarding a shipment of Buffycoats from that PIBC that would reasonably suggest
that it does not conform with Specifications or otherwise should not be used
for the manufacture of parenteral use products, in which case such lots of
Buffycoats shall be deemed rejected and any prior acceptance if any shall be
deemed revoked. Such notification shall be promptly confirmed in writing if
first given by other means.

5.5 Rejected or Recalled Buffycoats. Any Buffycoats not accepted by VUSA, or
whose acceptance has been revoked, shall be destroyed by VUSA in accordance
with all applicable laws and VUSA's standard operating procedures (or, if
timely requested by the PIBC, returned to the PIBC at the PIBC's risk and
expense).

5.6 Reimbursement of Rejection and Recall Costs. In the event that VUSA
rightfully rejects or revokes the acceptance of, or any PIBC recalls any
Buffycoats, the PIBC supplying such Buffycoats shall be responsible for and
reimburse VUSA for all costs, liabilities and losses incurred by VUSA in
connection with destruction or return of such Buffycoats and the manufacture
and distribution of products made from Buffycoats that are subject to such
recall ("Recall Costs"), and for any amount paid ABC or the PIBCs by VUSA for
such Buffycoats or, if such Buffycoats cannot be promptly replaced, the cost of
cover ("Refund Amounts"). The PIBC supplying such Buffycoats shall promptly (a)
refund to VUSA or credit the VUSA account with the amount of the Recall Costs,
and (b) as requested by VUSA, refund to or credit the VUSA account with the
amount of the Refund Amounts, or replace the rejected Buffycoats.
Notwithstanding the foregoing, no PIBC shall be obligated to pay VUSA any
Recall Costs or Refund Amounts incurred as a result of a No-Fault Recall. ABC
shall cooperate with VUSA in fulfilling VUSA's rights to obtain Refund Amounts
and Recall Costs as set forth in this Section 5.6, including, without




                                       8
<PAGE>   10

limitation, implementing holdbacks, set-offs or refunds against any payments
owed to a PIBC which itself owes VUSA such Recall Costs or Refund Amounts. In
no event shall VUSA withhold any payments to ABC that relate to one PIBC's
supply of Buffycoats because of amounts claimed due from another PIBC.

6.       EQUITY INTEREST; SHAREHOLDER PROVISIONS.

6.1 Shares to Be Received by ABC. Upon the expiration of 24 months from the
Effective Date, or whenever the interim cost reimbursement is replaced by an
actual incremental cost reimbursement, whichever is sooner, ABC shall receive
100,000 shares of VUSA common stock ("Shares") as an advance on the first
Buffycoat delivery milestone, unless ABC has already received 100,000 such
Shares based on 6.2. ABC may, subject to the terms of this Agreement,
ultimately receive an equity participation of one (1) million Shares (including
the 100,000 shares described above) based on an aggregate delivery of 5,000,000
Buffycoats by the PIBCs.

6.2 Issuance of Shares. Fully-paid and non-assessable Shares that are free and
clear of all encumbrances except for those restrictions set forth in this
Agreement, Exhibit 3 and Exhibit 4, shall be issued to ABC within 90 days of
the end of each calendar year in increments of 100,000 Shares based on a
formula of 100,000 Shares per 500,000 conforming Buffycoats delivered by PIBCs.

6.3 Transfer of Shares by ABC. Shares may be transferred upon receipt, or at a
later date, from ABC to PIBCs; however, ABC shall pay the actual out-of-pocket
costs associated with transfers that occur at a later date.

6.4 VUSA's Capital Structure. As of the Effective Date, VUSA's authorized
capital consists of 10,000,000 Shares of common stock, $0.01 par value, of
which 5,333,333 Shares are issued and outstanding.

6.5 Stockholder's Agreement. VUSA and ABC agree, simultaneous with the first
issuance of VUSA Shares to ABC, to enter into a mutually agreeable Stockholders
Agreement (including the execution of an Investment letter satisfactory to
VUSA's legal counsel), a copy of which will be attached as Exhibit 3 upon its
execution.

6.6 Listing of VUSA Shares. In the event that VUSA effects a public
registration and offering of its common stock, it shall include at VUSA's
expense and ABC's request all or part the common stock conveyed to ABC under
this Agreement. In the event that VUSA fails to effect a public registration
and offering of its common stock, including the common stock conveyed to ABC
under this Agreement within three (3) years of the Effective Date, ABC and the
PIBCs shall have the right in accordance with applicable law to exchange their
Shares of VUSA common stock to the common stock of Viragen having the same fair
market value at the time of exchange. The fair market value for the Shares
shall be based on an independent evaluation, performed by qualified persons
approved by the VUSA Board of Directors and ABC. The fair market value of the
Viragen stock shall be based on the average closing price of Viragen stock
during a period beginning ninety-five trading days before the conversion date
and ending five days before the conversion date. Prior to any public
registration and offering or exchange, VUSA agrees to (i) provide ABC or its
designated director or observer (if there is one) reasonable financial
information on VUSA on at least a quarterly basis which ABC agrees to hold in
confidence in accordance with this Agreement and (ii) at all times reserve and
keep available, solely for issuance and delivery upon satisfaction of the
conditions for delivery set forth in this Agreement, the number of Shares
issuable to ABC hereunder.

6.7 ABC Right to Designate One Board Member. During the term of this Agreement,
but prior to the first issuance of VUSA shares to ABC, ABC may designate a
non-voting observer to VUSA's Board of Directors. At such time as ABC and/or
the PIBCs own stock in VUSA, ABC shall, at its election, have the







                                       9
<PAGE>   11

right to designate one voting director for VUSA's Board of Directors. The
parties agree to vote their shares in accordance with Exhibit 4 to enable the
election to the VUSA Board of any person so designated by ABC. Nothing herein
shall require ABC to designate such persons, and nothing herein shall prevent
ABC from designating such persons at any time after the Effective Date of the
Agreement, provided, that all designees meet VUSA's Board members good and
reasonable criteria as specified from time to time by VUSA. The ABC designated
observer or Director shall be entitled to the same reimbursement for travel to
board meetings as is provided to other VUSA Directors. The ABC designated
Director shall be entitled to the same Director compensation, indemnification
and director's and officers liability insurance as similarly situated VUSA
Directors receive during the period that the ABC designated Director serves on
the Board.

6.8 Fair Market Issuance. VUSA agrees that it shall not issue or sell
(including as a dividend or other distribution on any class of stock)
additional common stock, or securities convertible into such common stock, for
a price below fair market value, as determined by the VUSA Board of Directors
at the time of such issuance or sale, provided that such determination must be
fair and reasonable.

7.       MARKETING AND DISTRIBUTION OF OMNIFERON.

The parties acknowledge that the PIBCs may be interested in distributing
Omniferon to the hospital market in the U.S.. VUSA agrees to provide good faith
consideration to any ABC proposal to distribute Omniferon to hospitals or
clinics to which ABC or the PIBC distribute blood products, but VUSA shall have
the right to negotiate and execute definitive marketing and distribution
agreement (s) with any Person(s) and on any terms that VUSA determines in its
sole discretion are appropriate. Notwithstanding the foregoing, VUSA agrees not
to enter into a distribution only agreement with a blood center that is not a
PIBC without first providing ABC with a good faith opportunity to negotiate
distribution only rights for Omniferon on commercially reasonable terms;
provided, however that VUSA, Viragen and their Affiliates are not obligated in
any manner to enter into any such distribution, marketing or other agreements
with ABC or any other Person.

8        INTELLECTUAL PROPERTY & CONFIDENTIAL INFORMATION.

8.1 Restricted Use of Confidential Information. Each party agrees that all
Confidential Information disclosed to it shall be used by it during the Term
and exclusively for the purpose of performing its obligations hereunder. ABC
and the PIBCs shall use VUSA's Buffycoat Specifications and other Confidential
Information during the Term for the sole purpose of supplying Buffycoats to
VUSA and its designated Affiliates or other VUSA designees. The parties intend
and agree that notwithstanding anything to the contrary in this Agreement, no
course of conduct or future authorizations shall be, or be interpreted as
being, an assignment or grant to ABC or the PIBCs of any right, title or
interest in or license to the Specifications or any Confidential Information or
any patent, trade secret, trade dress, copyright, trade mark, materials, or any
other type of intellectual or personal property now or in the future owned or
licensed by Viragen, VUSA or their Affiliates. It is agreed that ABC and the
PIBCs compensation, access to VUSA Confidential Information and technical
assistance under this Agreement is in part in consideration of the rights
granted and obligations undertaken under this Section 7, and that this Section
is a material and negotiated term of the Agreement.

8.2 Confidential Treatment. Each party shall protect the other party's
Confidential Information from unauthorized use, access or disclosure and shall
maintain such Confidential Information under conditions that would reasonably
prevent such unauthorized use, access or disclosure (including effective
controls over physical and electronic access). No party shall, without the
prior written consent of the other party which it may withhold at its sole
discretion, use, disclose, or permit the use or disclosure of such Confidential
Information in any manner whatsoever in whole or in part, except: (i) only for
performance of the party's obligations hereunder; and (ii) only to such
employees and officers of the receiving party to






                                      10

<PAGE>   12

the extent that such employees or officers need to know the Confidential
Information for performing the receiving party's obligations hereunder (and
then only such Confidential Information as such employee or officer needs to
know for performance of their assigned tasks); and (iii) all such employees and
officers have been first informed of confidential nature and ownership of the
Confidential Information and have first executed a written confidentiality and
intellectual property assignment agreement enforceable by and satisfactory to
the disclosing party.

8.3 Information Excluded. The receiving party's obligations shall not apply to
any particular Confidential Information to the extent that the receiving party
clearly and convincingly demonstrates that the particular Confidential
Information: (i) was in its possession prior to disclosure to it or its
development through work performed under this Agreement; (ii) was generally and
publicly known and accessible at the time of disclosure or thereafter through
no fault of the receiving party; or (iii) was rightfully furnished to the
receiving party on a non-confidential basis by a third party who was not
directly or indirectly breaching any obligations or duties to ABC, the PIBCs,
Viragen, VUSA or their Affiliates. The exceptions provided under this Section
8.3 shall not apply to any information that is considered to be Confidential
Information by a party because of its selection, organization, aggregation,
format, manner of presentation, or existence in electronic media.

8.4 Required Disclosure. Each party agrees that if it becomes legally compelled
or obligated to disclose any of the other party's Confidential Information, it
will provide such other party with prompt written notice and all lawful and
reasonable assistance to enable the other party to seek a protective order or
other appropriate remedy. If such protective order or other remedy is not
timely obtained, the party compelled to make such disclosure shall only furnish
that portion of the Confidential Information which, on the advice of counsel,
it reasonably determines it is legally required to furnish and will use
reasonable efforts to limit the scope of disclosure and obtain confidential
treatment or protective orders for such disclosed Confidential Information.

8.5 Return on Termination & Notification of Misappropriation. Upon this
Agreement's termination, each party shall return to the other party all
Confidential Information acquired by it from such other party and all copies
and abstracts thereof (whether in electronic, paper or other format). Each
party agrees that it shall immediately notify the other party in writing of any
suspected unauthorized disclosure or use of that party's Confidential
Information in its possession, and shall take and assist such other party in
taking all lawful means, including bringing and diligently prosecuting civil
and criminal complaints, to abate such unauthorized use or disclosure.

8.6 New Inventions. From time to time, new improvements, modifications,
materials, discoveries, works, marks, names, inventions, trade dress, and other
intellectual property may be jointly or separately conceived, reduced to
practice, invented, developed, discovered or made by the parties in connection

and/or the (ii) assistance of VUSA and Viragen employees, consultants and
contractors, and/or (iii) work performed under this Agreement by the any of the
parties (all of which are collectively the "New Inventions"). ABC or the PIBCs
shall promptly inform VUSA in writing of all such New Inventions upon their
creation and treat them as VUSA's Confidential Information. New Inventions do
not include ABC's proprietary methods, procedures or technology, or
improvements, or modifications thereof, to the extent not based on or derived
from (i) the use of or access to the VUSA/Viragen Confidential Information,
and/or the (ii) assistance of VUSA and Viragen employees, consultants and
contractors.

     (i)  OWNERSHIP OF NEW INVENTIONS. The parties agree that any and all New
          Inventions (whether or not they are patentable, copyrightable or
          otherwise protected under existing or future intellectual property
          rights) shall be entirely and exclusively owned by VUSA and are
          hereby entirely and irrevocably assigned (including all patents and
          copyrights) by ABC and the PIBCs to VUSA without reservation or
          further obligation or consideration that in any way relate to or
          arise out (i) of

          including but not limited to the Specifications and means of
          manufacturing human source leukocytes), trade secret or patent
          (including any unissued patent applications) or (ii) to any VUSA or
          Viragen current or contemplated product. VUSA will have the sole
          right to determine the treatment of such New Inventions, including
          the right to keep it as trade secrets, to file and execute patent
          applications on it, to use and disclose it without prior patent
          application, to file registrations for copyright or trade or other
          marks in its own name, or to follow any other procedure that VUSA
          deems appropriate. VUSA shall have the right to a worldwide,
          sublicenseable and exclusive, or at its election non-exclusive,
          license on commercially reasonable terms to any or all rights ABC or
          the PIBCs may have in all other New Inventions.

     (ii) ABC AND PIBC OBLIGATIONS. At VUSA's sole cost and expense, ABC and
          the PIBCs shall execute and provide, and shall cause its employees,
          officers, directors and contractors to execute and provide) all
          documents, testimony affidavits, and other reasonable acts and
          cooperation as may be necessary for perfection of VUSA's rights under
          this Agreement and for the filing, prosecution and enforcement of any
          patent applications or patents issued thereon. ABC and the PIBCs
          hereby grants the Secretary of VUSA, and his designee, its
          irrevocable power-of-attorney and hereby irrevocably appoints same as

          and to enforce VUSA's rights under this Section 8.

     (iii)SEPARATE RESEARCH AGREEMENTS; PIBC CONTRIBUTION. If any New Invention
          arises from a specific research program undertaken by the parties
          under a separate research agreement, the rights of the parties in and
          to such New Invention shall be in accordance with the terms of such
          separate research agreement. Without prejudice to VUSA's rights under
          Section 8.6, to the extent that any New Invention that is to be owned
          by VUSA under Section 8.6, has been conceived and reduced to practice
          entirely or substantially by PIBC employees, the parties shall in

and during which period the obligations under Section 2.10 shall not be in
effect.

10.6 Material Breach. ABC may terminate this Agreement, and each PIBC
may terminate its Subagreement, in the event of VUSA's material breach of the

undissolved consent decrees) and all other governmental authorities governing
their operations and other actions committed to be taken by them under the
Agreement and the Subagreements, and to maintain all permits, licenses and
approvals necessary to carry out their obligations under this Agreement and the
Subagreements; provided, a failure to comply with such laws or regulations
shall not be considered a material breach of this Agreement if such
non-compliance would not materially affect the regulatory compliance or
regulatory or other liabilities of the other parties, or VUSA's risks or
ability to use the delivered Buffycoats. ABC and each PIBC agree to permit and
cooperate with any audit of inspection by representatives of Viragen, VUSA, FDA

obligations hereunder or under any Subagreement, shall be assigned by any party
hereto without the prior written consent of the other party; provided, that (a)
the rights, but not the obligations, of a party herein may be assigned to one

perform on its behalf any of such party's obligations, and (c) any party may
assign all of its rights and obligations to any purchaser of all or

damages and are incapable of being precisely measured. Accordingly, the parties
agree that in the event of a breach or threatened breach, the other party(ies)

as practical implements the purposes hereof.

due and owing at the time of such occurrence nor shall any party be excused
because of any events to the extent that they could or might have been
prevented through the exercise of reasonable commercial judgment, care and
diligence.

15.14 Modifications in Writing. This Agreement, and its Subagreements, may not
be supplemented, modified or amended, except by an instrument in writing signed
by the parties hereto, and for the Subagreement by the affected PIBC. Any

responsibility for ensuring, and shall use it best efforts to secure each
PIBC's compliance with that PIBC's obligations under this Agreement and the
PIBC's Subagreement; provided, however, that ABC shall not be responsible for
damages to the extent such damages are caused by that PIBC's breach of its

         percentage set forth in Exhibit 3 hereto, and (ii) the average closing
         price of the Company's shares for the five (5) trading days prior to
         the payment due date. ARC shall have registration rights with respect

         by a certificate of all test results for such shipment and
         certification that the shipment of Buffycoats conforms with its
         Specifications, including the date, time and location where such

         in the manufacture of Buffycoats), in which case (and in the case of
         any lots not accepted, or that are rejected or for which the acceptance
         is revoked) such lots shall be deemed rejected and amounts paid
         (including any amounts paid in the form of Company common stock) shall
         be promptly refunded to VUSA or credited to VUSA's account as
         designated by VUSA. VUSA, at ARC's instruction, and sole expense and
         risk, will return the Buffycoat packing boxes to ARC by ARC's
         designated carrier.

                  (b) VUSA may from time to time test or have tested, for its
         own benefit, of the Buffycoat shipments and materials made therefrom.
         Any shipment determined to not conform with Specifications, because of
         latent defect or otherwise, shall be deemed rejected and amounts paid
         (including any amounts paid in the form of Company stock) shall be

         Agreement and all applicable laws and regulations pertaining to its
         operations.

     2.2 TIMING OF SHIPMENTS OF BUFFYCOATS. Subject to the delivery schedule
provided with Buffycoat Purchase Order, VUSA and ARC shall cooperate to ensure
that the Buffycoats to be purchased by VUSA from ARC are shipped in an orderly
manner so as to allow VUSA to utilize them efficiently in the manufacture of its
products. Without limiting the generality of the foregoing ARC shall not ship
Buffycoats to be received by VUSA on any day if VUSA gives ARC written notice (a
"No Ship Notice") that the VUSA Facility will not be operating on any day or
days, ARC shall not ship any Buffycoats to be received by VUSA on such day or
days provided that the No Ship Notice is faxed by VUSA to each Region then
shipping Buffycoats to VUSA not later than noon of the day preceding the day
such Buffycoats are collected. ARC shall furnish to VUSA from time to time the
fax numbers of the Regions then shipping Buffycoats to VUSA. ARC shall notify

use or disclosure.

     3.5 INJUNCTIVE RELIEF. Each party hereto acknowledges and agrees that any
breach by such party of the provisions of this Section 3 would cause immediate
and irreparable harm to the other party, and that the resulting damages and
injuries to such other party would be incalculable and irremediable in terms of
monetary damages. Accordingly, the parties agree that, in the event of such

         stated therein or necessary to make the statements therein, in light of

                  (g) VUSA will ensure the compliance with all applicable laws,

         local regulatory agency (collectively "Agencies") having jurisdiction
         over the manufacturing of Natural Alpha Interferon; provided, that
         violations of laws, rules, regulations, and recommendations shall not
         be deemed a breach of this warranty or cause for termination by ARC

         material and continuing threat to the public health, and (ii) are not
         promptly remedied by VUSA in a time and manner satisfactory to such
         Agencies.

     6. TERMINATION

     6.1 TERM OF AGREEMENT. The initial term of this Agreement shall be for
fifteen (15) years from the Effective Date.

                  (a) During the seventh year of this Agreement, any party may
         terminate it with or without cause upon delivery to the other parties
         of written notice at least ninety (90) days before the seventh
         anniversary date, in which case it shall be terminated on, but no
         earlier than, the seventh anniversary of the Effective Date.

                  (b) If the Agreement is not terminated on its seventh
         anniversary, then the Agreement shall automatically be extended through
         its eleventh anniversary.

                  (c) Upon the eleventh anniversary of the Effective Date, and
         for each year thereafter, this Agreement shall automatically renew,
         without limitation, for successive one (1) year periods unless a party
         delivers to the other parties written notice at least

         ninety (90) days before the subsequent anniversary date that it will
         not renew the Agreement.

                  (d) Six months prior to the end of the initial Supply Period,
         the parties agree to negotiate in good faith prices, discounts, rebates
         and quantities for the subsequent Supply Period. Notwithstanding
         anything to the contrary herein, no party shall be obligated in any
         manner whatsoever to agree on any particular terms for prices
         discounts, rebates or quantities for the subsequent Supply Period,
         other than the terms that such party in its sole commercial discretion
         deems acceptable, which may take into account, among other
         considerations, the performance of the other parties under this
         Agreement, the availability of and terms obtainable from alternative
         vendors and suppliers, and future requirements and available supply. A
         failure by the parties to agree upon price, discounts, rebates or
         quantities for prior to the first two calendar quarters of the Supply
         Period for which such negotiations apply shall not serve to negate,
         modify or terminate this Agreement. If the parties fail to agree upon
         the prices, discounts, rebates and quantities for the subsequent Supply
         Period prior to the beginning of Supply Period, then all rights and
         obligations of the parties under this Agreement (except for the
         confidentiality and quality assurance provisions and the payment of any
         amounts or rebates due under this Agreement), shall be temporarily
         suspended on a quarterly basis until such time as the parties agree to
         such terms; provided, that if the parties do not reach a definitive and
         complete agreement on the supply terms for the subsequent Supply Period
         prior to the end of the second calendar quarter of such Supply Period
         then this Agreement shall at the election of and notice by either party
         become immediately terminated.

     6.2 RIGHTS TO TERMINATE. This Agreement may be terminated prior to the
scheduled end of the Term by a party (the "terminating party") as follows, by
notice as provided in Section 6.1:

                  (a) by any party, if another party breaches in any material
         respect any of its material obligations or warranties under this
         Agreement and such breach, if capable of being cured, shall not have
         been cured within 90 days after notice of such breach to the breaching
         party from the terminating party or, if such breach is capable of being
         cured but not within such 90-day period, then within such period as is
         reasonably necessary to effect a cure so long as the breaching party

party, except to the extent specifically provided otherwise herein) any rights,
benefits, obligations or remedies of any nature whatsoever under or by reason of
this Agreement.

     9.5 LIMITATIONS ON LIABILITY. In no event shall any party hereto have any
liability, whether based on contract, tort (including, without limitation,
negligence), or any other legal or equitable grounds, for any loss of interest,
profit or revenue by any other party hereto or of any consequential, indirect,
special, punitive or exemplary damages suffered by any other party hereto.

     9.6 HEADINGS. The headings in this Agreement are solely for convenience of
reference and shall be given no effect in the construction or interpretation of
this Agreement.

     9.7 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

     9.8 ASSIGNMENT. Neither this Agreement nor any of the rights, interests, or
obligations hereunder shall be assigned by either party hereto without the prior
written consent of the other party; provided, that (a) the rights but not
obligations of any party herein may be assigned to one or more of such party's

assets of the part of such party's or its Affiliates' business which relates to
the subject of this Agreement. No assignment shall relieve either party of

then has hereunder.

     9.9 MODIFICATION. This Agreement and the Schedules hereto set forth the
entire understanding of the parties with respect to the subject matter hereof,
supersede all existing agreements among them concerning such subject matter, and
may be modified only by a written instrument duly executed by each party.

     9.10 SEVERABILITY & INTEGRATION. If any term or provision of this Agreement
shall for any reason be held invalid, illegal, or unenforceable in any respect,
such invalidity, illegality, or unenforceability shall not affect any other term
or provision hereof, and this Agreement shall be interpreted and construed as if
such term or provision, to the extent the same shall have been held to be valid,
illegal, or unenforceable, had never been contained herein. This Agreement,
together with its Exhibits, are intended to be the final and full agreement
between the parties, and supersedes all prior discussions, negotiations,
agreements, letters of intent, term sheets, heads of agreements and other
written, oral and other communications; provided that all obligations under the
"Confidentiality Agreement," dated January 24, 1996 between VUSA and ARC, shall
be deemed to be continued and merged into the obligations under this Agreement.

     9.11 WAIVER. Any waiver by either party of a breach of any term of this
Agreement shall not operate as or be construed to be a waiver of any other
breach of that term or of any breach of any other term of this Agreement,

<PAGE>   19

circumstance. The failure of a party to insist upon strict adherence to any term
of this Agreement on one or more occasions will not be considered a waiver or
deprive that party of the right thereafter to insist upon strict adherence to
that term or any other term of this Agreement. The provision hereunder of one or
remedies, shall be additive to all other remedies available to the parties under
this agreement or applicable law, and the exercise of such remedy shall not
limit a party in seeking or obtaining such other a remedies. Any waiver must be
in writing signed by a person who is authorized by the party making such waiver
to execute such document.

     9.12 JURISDICTION. Each of the parties hereby irrevocably consents to the

be determined in accordance with Virginia law; provided, that disputes
pertaining securities, corporate governance and any rights or obligations
relating to the stock or warrants of VUSA or the Company shall be determined
under Delaware, and, where applicable, Federal law. The party materially and
substantively prevailing in any litigated or arbitrated dispute is entitled to
award of its costs, including the fees and expense of attorneys and other
professionals, in connection with litigating such dispute. No provision of this
Agreement shall be construed against any party by reason of that party having
drafted the same.

     9.13 PUBLIC ANNOUNCEMENTS. Neither party shall issue any press release or
otherwise make any public statement with respect to this Agreement or any of the
transactions contemplated hereby without first consulting with and (unless such
press release or statement is required by applicable law or the requirements of
any listing agreement with any applicable stock exchange or inter-dealer
quotation system, or other requirement to identify its suppliers of human
leukocytes) obtaining the consent of the other party, which consent shall not be
unreasonably withheld.

recognizes that the "American Red Cross" name and emblem represents ARC's most
valuable assets and that substantial recognition and goodwill is associated with
this name, emblem and other various trademarks and service marks of ARC. The

other trademarks or service marks of ARC without the prior written authorization
from ARC. Nothing in this Agreement, exclusive of Section 9.13 with respect to
the name "American Red Cross" or "ARC", constitutes such authorization.

         VUSA REBATE PROGRAM ON BUFFYCOAT PURCHASES

VUSA shall be entitled to receive a rebate on Buffycoat purchases (in dollars),
up to a maximum of 20% of the ARC's net gain (appreciation minus selling
expenses) on the Company's shares from the Warrant, based on the percentage net
gain accrued by ARC through the receipt of the Warrant, as follows:

                                                              VUSA REBATE

                         0% to 10%                              No Discount
                         10% to 25%                                  4%
                         25% to 50%                                  8%
                         50% to 75%                                 12%
                        75% to 100%                                 16%
                     Greater than 100%                              20%

         The rebate on actual net gains resulting from the sale of the Company's
common stock received by ARC through the exercise of the Warrant shall be paid
to VUSA in the quarter following the sale of the stock.

         The rebate on unrealized net gains resulting from the increase in the
Company's share price on shares purchased or vested under the Warrant shall be
as follows:

1.       The rebate for each of the four blocks of common stock underlying the
         Warrant will apply specifically to the two-year period of time to which
         the shares are linked (through the volume discount price schedule). The
         rebate on unrealized net gains will apply to each of the four blocks of
         common stock under the Warrant only once, at the end of the two-year
         period linked to the common stock through the price agreement. No
         rebate for unrealized gains shall be due any shares for which a rebate
         based on realized gains has been paid, and no rebate for realized gains
         shall be due any shares for which a rebate based on unrealized gains
         has been paid.






                                Exhibit 2 Page 1
<PAGE>   23

2.       The net unrealized gain on the shares of common stock will be
         calculated at the end of each two-year period linked to each of the
         four blocks of common stock under the warrant.

3.       The calculation of the net unrealized gain will be based on the
         increase in the Company's share price over the stated exercise price.
         The Company's share price will be defined as the average of the closing
         price of its common stock for the four calendar quarters preceding the
         end of the two-year period. Since the shares of common stock will not
         have been sold, an estimate will be made of the future selling expenses
         to calculate the net unrealized gain.

4.       The rebate will be applied by VUSA to its ARC account on the later of
         the dates that the shares linked to the two-year period are registered
         with the SEC, or three (3) months after the end of the two-year period.

             (INCORPORATED UNDER THE LAWS OF THE STATE OF DELAWARE)

               WARRANT FOR THE PURCHASE OF SHARES OF COMMON STOCK
               --------------------------------------------------

ARC-1

         FOR VALUE RECEIVED, VIRAGEN, INC. (the "Company"), a Delaware
corporation, having its principal offices at 865 S.W. 78th Avenue, Suite 100,
Plantation, Florida 33324, grants to THE AMERICAN NATIONAL RED CROSS, a
charitable and not-for-profit corporation having its principal offices in Falls
Church, Virginia 22042 (the "Holder"), the right to purchase from the Company up
to 500,000 fully paid and non-assessable shares of Common Stock at a price per
share (the "Exercise Price"), term and vesting schedule and conditions
hereinafter set forth.

         This Warrant is issued pursuant to that certain Agreement made and
entered into as of August 12, 1998 by and among the Holder, Viragen U.S.A.,
Inc., ("VUSA") and the Company (the "Agreement"). Certain terms and conditions
pertaining to the vesting of the right to purchase shares of Common Stock of the
Company are predicated on the parties to the Agreement agreeing to certain

of the Agreement provides the Company or its affiliates or designees with a
right of first refusal under certain conditions as provided therein.

         The term "Common Stock" means the Common Stock, par value $.01 per
share, of the Company. The number of shares of Common Stock to be received upon
the exercise of this Warrant may be adjusted from time to time as hereinafter
set forth. The shares of Common Stock deliverable upon such exercise, and as
adjusted from time to time, are hereinafter referred to as "Warrant Stock." The
term "Other Securities" means any other equity or debt securities that may be
issued by the Company in addition thereto or in substitution for the Warrant
Stock. The term "Company" means and includes the corporation named above as well
as (i) any immediate or more remote successor corporation resulting from the
merger or consolidation of such corporation (or any immediate or more remote
successor corporation of such corporation) with



                                       1
<PAGE>   27

another corporation, or (ii) any corporation to which such corporation (or any
immediate or more remote successor corporation of such corporation) has
transferred its property or assets as an entirety or substantially as an
entirety.

         The Holder agrees with the Company that this Warrant is issued, and all
the rights hereunder shall be held subject to, all of the conditions,
limitations and provisions of the Agreement to which this Warrant is attached
and as set forth herein.

         1. WARRANT SCHEDULE AND EXERCISE PRICES. This Warrant shall vest for
the number of shares of Warrant Stock, for the term and at Exercise Prices set
forth as follows:

<TABLE>
<CAPTION>

       GRANT DATE               VEST DATE              # OF SHARES                 TERM               EXERCISE PRICE
       ----------               ---------              -----------                 ----               --------------

    August 12, 1998          August 12, 1998                50,000          2 years from vest          $ 5.50/share
    August 12, 1998          August 12, 2000               100,000          2 years from vest          $ 7.50/share
    August 12, 1998          August 12, 2002               150,000          3 years from vest          $ 9.00/share
    August 12, 1998          August 12, 2004               200,000          4 years from vest          $11.00/share

</TABLE>

         The vesting schedule for the above Warrant Stock in the Agreement is
contingent upon the Holder and VUSA executing mutually agreeable two-year
buffycoat pricing schedules and rebate program by the respective vesting dates
for the applicable Warrant Stock as provided for in Section 6.1(d) of the
Agreement. Specifically, the 100,000 block of Warrant Stock is conditioned upon
price agreement for the years (i.e. 24-month period) 2000-2002; the 150,000
block of Warrant Stock is conditioned upon price agreement by the parties for
the years 2002-2004; and the 200,000 block of Warrant Stock is conditioned upon
price agreement for the years 2004-2006. In addition, the 200,000 block of
Warrant Stock is further conditioned upon extension of the Agreement prior to
the end of year 7 as provided in Section 6.1(b) of the Agreement. The foregoing
notwithstanding, in the event the Holder and VUSA shall have failed to come to
an agreement with regard to the pricing schedule and rebate program for the
applicable two-year period supporting the vesting of the Warrant Stock by the
aforementioned vest date, then commencing with each of the respective vest dates
and for each three-month period following the vest date that the Holder and VUSA
have failed to reach such pricing and rebate agreement, one eighth (1/8) of the
proposed Warrants to be vested for that applicable two-year period shall become
null and void.

         2. EXERCISE OF WARRANT. Following vesting, this Warrant may be
exercised as to the specified amount of Warrant Stock, in whole or in part, but
if in part, in minimum increments of 50,000 shares at any time, or from time to
time during the period commencing on the vesting date and expiring 5:00 p.m.
Eastern Time on the date of expiration or termination of the Agreement to which
this Warrant is attached (the "Expiration Date") or, if such day is a day on
which banking institutions in New York are authorized by law to close, then on
the next succeeding day that shall not be such a day, by presentation and
surrender of this Warrant to the Company at its principal office with the
Warrant Exercise Form attached hereto duly executed and accompanied by payment
(either in cash or by certified or official bank check, payable to the order of
the Company or by delivery of the Holder's Promissory Note in the form attached
as Exhibit A) of the Exercise Price for the number of shares specified in such
form and instruments of transfer, if appropriate, duly executed by the Holder or
its duly authorized attorney. If this Warrant should be exercised in part





                                       2
<PAGE>   28

only, the Company shall, upon surrender of this Warrant for cancellation,
execute and deliver a new Warrant evidencing the rights of the Holder thereof to
purchase the balance of the shares purchasable hereunder. Upon receipt by the
Company of this Warrant, together with the payment of the Exercise Price at its
office in proper form for exercise, the Holder shall be deemed to be the holder
of record of the shares of Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or that certificates representing such shares of Common Stock shall not
then be actually delivered to the Holder. The Company shall pay any and all
documentary stamp or similar issue or transfer taxes payable in respect of the
issue or delivery of shares of Common Stock on exercise of this Warrant.

         3. REGISTRATION RIGHTS. The Company has provided registration rights
with respect to the Warrant Stock as provided in that certain Registration
Rights Agreement dated even date herewith.

         4. RESERVATION OF SHARES. The Company will at all times reserve for
issuance and delivery upon exercise of this Warrant all shares of Common Stock
or other shares of capital stock of the Company (and Other Securities) from time
to time receivable upon exercise of this Warrant. All such shares (and Other
Securities) shall be duly authorized and, when issued upon such exercise, shall
be validly issued, fully paid and non-assessable and free of all preemptive
rights.

         5. FRACTIONAL SHARES. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise Of this Warrant, but the
Company shall pay the holder an amount equal to the fair market value of such
fractional share of Common Stock in lieu of each fraction of a share otherwise
called for upon any exercise of this Warrant. For purposes of this Warrant, the
fair market value of a share of Common Stock shall be determined as follows:

                  (a) If the Common Stock is listed on a National Securities
         Exchange or admitted to unlisted trading privileges on such exchange or
         listed for trading on the NASDAQ system, the current market value shall
         be the last reported sale price of the Common Stock on such exchange or
         system on the last business day prior to the date of exercise of this
         Warrant or, if no such sale is made on such day, the average of the
         closing bid and asked prices for such day on such exchange or system;
         or

                  (b) if the Common Stock is not so listed or admitted to
         unlisted trading privileges, the current market value shall be the mean
         of the last reported bid and asked prices reported by the National
         Quotation Bureau, Inc. on the last business day prior to the date of
         the exercise of this Warrant; or

                  (c) If the Common Stock is not so listed or admitted to
         unlisted trading privileges and bid and asked prices are not so
         reported, the current market value shall be an amount, not less than
         book value thereof as at the end of the most recent fiscal year of the
         C6mpany ending prior to the date of the exercise of the Warrant,
         determined in such reasonable manner as may be prescribed by the Board
         of Directors of the Company.

         6. RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder in the Company, either at law or in
equity, and the rights of the Holder are limited to those expressed in this
Warrant.

<PAGE>   29

         7. ANTI-DILUTION PROVISIONS.

         7.1 ADJUSTMENT FOR RECAPITALIZATION. If the Company shall at any time
subdivide its outstanding shares of Common Stock (or Other Securities at the
time receivable upon the exercise of the Warrant) by recapitalization,
reclassification or split-up thereof, or if the Company shall declare a stock
dividend or similar distribution of shares of Common Stock to its stockholders,
the number of shares of Common Stock subject to this Warrant immediately prior
to such subdivision shall be proportionately increased, and the Exercise Price
shall be proportionately decreased, and if the Company shall at any time combine
the outstanding shares of Common Stock by recapitalization, reclassification or
combination thereof, the number of shares of Common Stock subject to this
Warrant immediately prior to such combination shall be proportionately
decreased, and the Exercise Price shall be proportionately increased. Any such
adjustments pursuant to this Section 7.1 shall be effective at the close of
business on the effective date of such subdivision or combination, or if any
adjustment is the result of a stock dividend or distribution, then the effective
date for such adjustment based thereof shall be the record date therefor.

         7.2 ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC. In case
of any reorganization of the Company (or any other a corporation, the securities
of which are at the time receivable on the exercise of this Warrant), or in case
after such date the Company (or any such other corporation) shall consolidate
with or merge into another corporation or convey all or substantially all of its
assets to another corporation, then, and in each such case, the Holder of this
Warrant upon the exercise thereof as provided in Section 1 at any time after the
consummation of such reorganization, consolidation, merger or conveyance shall
be entitled to receive, in lieu of the securities and property receivable upon
the exercise of this Warrant prior to such consummation, the securities or
property to which such Holder would have been entitled upon such consummation if
such Holder had exercised this Warrant immediately prior thereto; in each such
case, the terms of this Warrant shall be applicable to the securities or
property receivable upon the exercise of this Warrant after such consummation.

         7.3 NOTIFICATION AS TO ADJUSTMENTS. In each case of an adjustment in
the number of shares of Common Stock receivable on the exercise of the Warrant,
the Company at its expense will promptly compute such adjustment in accordance
with the terms of the Warrant and will notify the Holder in writing of such
adjustment within 30 days of the effective date of such adjustment. When
appropriate, notice may be given in advance as part of notices required to be
mailed to the Holder pursuant to Section 7.5 hereof.

         7.4 OTHER ISSUANCES. Except as otherwise expressly provided herein, the
issuance by the Company of shares of its capital stock of any class, or
securities convertible into shares of capital stock of any class, either in
connection with a direct sale or upon the exercise of rights or warrants to
subscribe therefore, or upon conversions of shares or obligations of the Company
convertible into such shares or other securities, or as compensation or
otherwise, shall not affect, and no adjustment by reason thereof shall be made
with respect to, the number of or the exercise price of the Shares that remain
unexercised under the Warrant.





                                       4
<PAGE>   30

         Without limiting the generality of the foregoing, the existence of
unexercised Shares under the Warrant shall not affect in any manner the right or
power of the Company to make, authorize or consummate (i) any issuances as
described above, (ii) any or all adjustments, recapitalizations, reorganizations
or other changes in the Company's capital structure or its business; (iii) any
merger or consolidation of the Company; (iv) any issue by the Company of debt
securities, or preferred or preference stock that would rank above the Shares
issuable upon exercise of the Warrant; (v) the dissolution or liquidation of the
Company; (vi) any sale, transfer or assignment of all or any part of the assets
or business of the Company; or (vii) any other corporate act or proceeding,
whether of a similar character or otherwise.

         7.5 NOTICES OF RECORD DATE, ETC. In case:

                  (a) the Company shall take a record of the holders of its
Common Stock (or Other Securities at the time receivable upon the exercise of
the Warrant) for the purpose of entitling them to receive any dividend (other
than a cash dividend at the same rate as the rate of the last cash dividend
theretofore paid) or other distribution, or any right to subscribe for, purchase
or otherwise acquire any shares of stock of any class or any other securities,
or to receive any other right; or

                  (b) of any capital reorganization of the Company, any
reclassification of the capital stock of the Company, any consolidation or
merger of the Company with or into another corporation, or any conveyance of all
or substantially all of the assets of the Company to another corporation; or

                  (c) of any voluntary or involuntary dissolution, liquidation
or winding up of the Company, then, and in each such case, the Company shall
mail or cause to be mailed to each Holder of the Warrant at the time outstanding
a notice specifying, as the case may be, (i) the date on which a record is to be
taken for the purpose of such dividend, distribution or right, and stating the
amount and character of such dividend, distribution or right, or (ii) the date
on which such reorganization, reclassification, consolidation, merger,
conveyance, dissolution, liquidation or winding up is to take place, and the
time, if any, is to be fixed, as to which the holders of record of Common Stock
(or such Other Securities at the time receivable upon the exercise of the
Warrant) shall be entitled to exchange their shares of Common Stock (or such
Other Securities) for securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger conveyance, dissolution,
liquidation or winding up. Such notice shall be mailed at least 20 days prior to
the date therein specified, and the Warrant may be exercised prior to said date
during the term of the Warrant.

         8. TRANSFER TO COMPLY WITH THE SECURITIES ACT. The Warrant Stock or
Other Securities may not be sold, transferred, pledged, hypothecated or
otherwise disposed of except as follows: (a) in a transaction exempt from
registration under the Securities Act including pursuant to Rule 144 thereunder;
(b) to a person who, in the opinion of counsel to the Company, is a person to
whom this Warrant or the Warrant Stock or Other Securities may legally be
transferred without registration and without the delivery of a current

                          REGISTRATION RIGHTS AGREEMENT

         AGREEMENT, dated as of the 12th day of August, 1998, by and between THE
AMERICAN NATIONAL RED CROSS, a charitable and not-for-profit corporation having
its principal offices in Falls Church, Virginia 22042 ("ARC") and VIRAGEN, INC.,
a Delaware corporation having its principal offices at 865 SW. 78th Avenue,
Suite 100, Plantation, Florida 33324 (the "Company").

         WHEREAS, simultaneously with the execution and delivery of this
Registration Rights Agreement, ARC, the Company and Viragen U.S.A., Inc.
("VUSA") are entering into an Agreement made and entered into as of August 12,
1998, (the "Agreement"), which provides, INTER ALIA, for ARC to have the right
to receive payments for ARC buffycoats in cash or shares of Common Stock of the
Company (such shares of Common Stock as may be issued pursuant to such election
by ARC is hereinafter be referred to as the "Shares"), and for the issuance of
up to 500,000 shares of Common Stock upon exercise of a warrant dated even date
therewith (the "Warrant") upon the terms and conditions set forth in the
Agreement and the Warrant (such shares of Common Stock as may be issued upon
exercise of the Warrant is hereinafter referred to as the "Warrant Stock"); and

         WHEREAS, the Company desires to grant to ARC the registration rights
set forth here in with respect to the Shares and the Warrant Stock:

         1. REQISTRABLE SECURITIES. As used herein the term "Registrable
Security" means collectively, the Shares and the Warrant Stock; provided,
however, that with respect to any particular Registrable Security, such security
shall cease to be a Registrable Security when, as of the date of determination,
(i) it has been effectively registered under the Securities Act of 1933, as
amended (the "Securities Act") and disposed of pursuant thereto, or (ii)
registration under the Securities Act is no longer required for the immediate
public distribution of such security. The term "Registrable Securities" means
any and/or all of the securities falling within the foregoing definition of a
"Registrable Security." In the event of any merger, reorganization,
consolidation, recapitalization or other change in corporate structure affecting
the Common Stock, such adjustment shall be made in the definition of
"Registrable Security" as is appropriate in order to prevent any dilution or
enlargement of the rights granted pursuant to this Article 1.

         2. PIGGYBACK REGISTRATION. If, at any time, the Company proposes to
prepare and file with the Securities and Exchange Commission (the "Commission")
a registration statement covering equity or debt securities of the Company, or
any such securities of the Company held by its stockholders (in any such case,
other than in connection with a merger, acquisition or pursuant



                                    1 of 12
<PAGE>   35

to Form S-8 or successor form) (for purposes of this Article 2, collectively, a
"Registration Statement"), it will give written notice of its intention to do so
by registered mail ("Notice") at least thirty (30) days prior to the filing of
each such Registration Statement to ARC. Upon the written request of ARC, made
within twenty (20) days after receipt of the Notice, that the Company include
any of the Shares and/or Warrant Stock in the proposed Registration Statement
(provided in the case of a request with regard to the Shares that VUSA and ARC
have executed mutually agreeable two-year buffycoat pricing schedules and rebate
programs as contemplated in the Agreement), the Company shall use its best
efforts to effect the registration under the Securities Act of the resale of the
Shares and/or Warrant Stock which it has been so requested to register
("Piggyback Registration"), at the Company's sole cost and expense and at no
cost or expense to ARC except as provided in Section 4E) hereof.

         Notwithstanding the provisions of this Article 2, (i) the Company shall
have the right at any time after it shall have given written notice pursuant to
this Article 2 (irrespective of whether any written request for inclusion of the
Shares shall have already been made) to elect not to file any such proposed
Registration Statement, or to withdraw the same after the filing but prior to
the effective date thereof; (ii) if the Company's managing underwriter, if any,
of the offering for which a Registration Statement has been filed so requests in
writing, the Shares shall not be offered or sold until the expiration of a date
not to exceed 90 days from the effective date of the offering that gave rise to
the Piggyback Registration, but any such request and deferral of the offer and
sale shall not affect the Company's obligation to register for resale under the
Securities Act the Shares.

         In the event of the termination of the Agreement by the Company and/or
VUSA pursuant to Section 6.2 thereof, the registration rights provided by this
Article 2 shall simultaneously terminate; and in the event of suspension of the
Agreement pursuant to Section 6.1(d) thereof, such registration rights shall be
correspondingly suspended. The termination or suspension of this Agreement shall
not affect the Company's and/or VUSA's obligations hereunder with respect to (i)
Warrant Stock that ARC has a vested right to acquire and/or Shares or (ii)
Warrant Stock and/or Shares subject to a then effective Registration Statement.

         3. DEMAND REGISTRATION. As set forth in the Warrant, there is provided
to ARC the right to purchase up to 500,000 Shares of Common Stock of the Company
which shall vest as to certain shares of Warrant Stock at various dates
commencing with August 12, 1998 through August 12, 2004. At the time of vesting
of each tranche of Warrant Stock as provided in the Warrant, ARC shall have the
right (which right is in addition to the Piggyback Registration provided for
under Article 2 hereof), exercisable by written notice to the Company (the
"Demand Registration Request"), to have the Company prepare and file with the
Commission on one occasion as to the Warrant Stock included in the tranche which
shall have vested, at the sole expense of the Company (except as provided in
Section 4(b)), a Registration Statement so as to permit a public offering and
sale of the Warrant Stock.





                                    2 of 12
<PAGE>   36

         As set forth in the Agreement, ARC has the right to receive certain
payments for ARC buffycoats in Shares. ARC shall have the right upon each
election to receive such Shares (which right is in addition to the Piggyback
Registration provided for in Article 2 hereof), and in the event the Company has
not theretofore included the Shares in any other current Registration Statement,
to have the Company prepare and file with the Commission, at the sole expense of
the Company (except as provided in Section 4(b)), a Registration Statement so as
to permit a public offering and sale of the Shares.

         Once effective, the Company will be required to maintain the
effectiveness of the Registration Statement with respect to each tranche of the
Warrant Stock or Shares registered in connection therewith until the earlier of
(i) the date that all of the Warrant Stock and/or the Shares have been sold, or
(ii) the date that all holders of Warrant Stock and/or Shares receive an opinion
of counsel to the Company that all of the Warrant Stock and/or Shares may be
freely traded without registration under the Securities Act, under Rule 144
promulgated under the Securities Act or otherwise. If ARC shall give notice to
the Company at any time of its desire to exercise the registration right granted
pursuant to this Article 3, then the Company shall use its best efforts to
effect, as soon as practicable and in any event within the time period specified
in Section 4(a)(i) hereof, the registration under the Securities Act of all
Warrant Stock and/or the Shares that ARC may request to be so registered.

         If ARC indicates that it intends to distribute the Warrant Stock and/or
the Shares covered by its Demand Registration Request by means of an
underwriting, ARC shall so advise the Company as a part of the notice given
pursuant to this Section 3. In the event of any underwritten public offering,
the Company shall enter into and perform its obligations under an underwriting
agreement, in usual and customary form, with the managing underwriter of such
offering. The underwriter will be selected by ARC and shall be an underwriter
reasonably acceptable to the Company.

         If at any time the Company registers any Warrant Stock and/or the
Shares under the Securities Act pursuant to this Section 3, the sale or other
disposition of such Warrant Stock and/or the Shares by ARC may be made pursuant
to a Registration Statement on Form S-3 under the Securities Act as in effect on
the date hereof or any registration form under the Securities Act subsequently
adopted by the Commission that permits inclusion or incorporation of substantial
information by reference to other documents filed by the Company with the
Commission, such Registration Statement shall be filed as a "shelf" registration
statement pursuant to Rule 415 under the Securities Act (or any successor rule).
Any such shelf registration shall cover the disposition of the Warrant Stock
and/or the Shares in one or more underwritten offerings, block transactions,
broker transactions, at-market transactions and in such other manner or manners
as may be specified by ARC. The Company shall use its best efforts to keep such
"shelf" registration continuously effective as long as the delivery of a
prospectus is required under the Securities Act in connection with the
disposition of the Warrant Stock and/or the Shares registered thereby and in
furtherance of such obligation, shall supplement or amend such Registration
Statement if, as and when required by the rules, regulations and instructions
applicable to the form used by the




                                    3 of 12
<PAGE>   37

Company for such registration or by the Securities Act or by any other rules and
regulations thereunder applicable to shelf registrations.

         Nothing herein shall require the Company to undergo an audit, other
than in the ordinary course of business.

         In the event of the termination of the Agreement by the Company and/or
VUSA pursuant to Section 6.2 thereof, or in the event of the early termination,
non-renewal or suspension of the Agreement pursuant to Section 6.1 thereof, the
registration rights provided by this Article 3 shall simultaneously terminate or
be suspended, as the case may be. The termination or suspension of this
Agreement shall not affect the Company's and/or VUSA's obligations hereunder
with respect to (i) Warrant Stock that ARC has a vested right to acquire and/or
Shares or (ii) Warrant Stock and/or Shares subject to a then effective
Registration Statement.

         4. COVENANTS OF THE COMPANY WITH RESPECT TO REGISTRATION. The Company
covenants and agrees as follows:

                  (a) (i) In connection with any registration under Articles 2
and 3 hereof, the Company shall use its best efforts to file the Registration
Statement as expeditiously as possible, but in no event later than forty-five
(45) days following receipt of any Notice or Demand Registration Request
therefor. The Company shall use its best efforts to cause the Registration
Statement to become effective as promptly as possible and, if any stop order
shall be issued by the Commission or order suspending qualification or
registration in any state in connection therewith, to use its reasonable efforts
to obtain the removal of such order. Following the effective date of a
Registration Statement, the Company shall, upon the request of ARC, forthwith
supply such reasonable number of copies of the Registration Statement,
preliminary prospectus and prospectus meeting the requirements of the Securities
Act, any supplements or amendments thereto, and other documents necessary or
incidental to the public offering of the Registrable Securities, as shall be
reasonably requested by ARC to permit ARC to make a public distribution of ARC's
Registrable Securities. ARC shall furnish the Company in a timely manner with
all information required by the applicable rules and regulations of the
Commission concerning the proposed method of sale or other disposition of such
Registrable Securities and such other information as may be reasonably requested
by the Company in writing properly to prepare and file such Registration
Statement, or any prospectus, supplement or amendment thereto in accordance with
the applicable provisions of the Securities Act.

                           (ii) The Company shall prepare and file with the
Commission such amendments (including post-effective amendments) and supplements
to such Registration Statement and the prospectus used in connection with such
Registration Statement as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such
Registration Statement.





                                    4 of 12
<PAGE>   38

                           (iii) Prior to filing the Registration Statement or a
prospectus or any amendments or supplements thereto, the Company shall furnish
ARC with copies of all such documents proposed to be filed, which documents will
be made available, on a timely basis, for review by ARC and its counsel, and ARC
and its counsel shall furnish comments thereon, if any, within five business
days of receipt of such Registration Statement, prospectus, amendments or
supplements.

                           (iv) The Company shall promptly advise ARC and
confirm such advice in writing, (1) when such Registration Statement or the
prospectus included therein or any prospectus amendment or supplement or
post-effective amendment has been filed, and, with respect to such Registration
Statement or any post-effective amendment, when the same has become effective,
(2) of any comments by the Commission, by the National Association of Securities
Dealers, Inc. ("NASD"), and by the blue sky or securities commissioner or
regulator of any state with respect thereto or any request by any such entity
for amendments or supplements to such Registration Statement or prospectus or
for additional information, (3) of the issuance by the Commission of any stop
order suspending the effectiveness of such Registration Statement or the
initiation or threatening of any proceedings for that purpose, (4) if at any
time the representations and warranties of the Company contained herein cease to
be true and correct in all material respects, (5) of the receipt by the Company
of any notification with respect to the suspension of the qualification of the
Registrable Securities for sale in any jurisdiction or the initiation or
threatening of any proceeding for such purpose, or (6) at any time when a
prospectus is required to be delivered under the Securities Act, that such
Registration Statement, prospectus, prospectus amendment or supplement or
post-effective amendment, or any document incorporated by reference in any of
the foregoing, contains an untrue statement of a material fact or omits to state
any material fact required to be stated therein or necessary to make the
statements therein in light of the circumstances under which they are made, not
misleading.

                           (v) Notwithstanding the provision under Section
4(a)(i) hereof, if, at the time the Demand Registration Request is given to the
Company under Article 3 hereof, the Company is negotiating a merger,
consolidation, acquisition or sale of all or substantially all of its assets or
similar transaction and in the written opinion of counsel to the Company, the
Registration Statement would be required to include information concerning such
transactions or the parties thereto that is not available at the time, the
Company shall promptly so advise ARC and, at the Company's election, to be set
forth in such notice ("Notice of Postponement"), the filing of the Registration
Statement may be postponed for a period not to exceed ninety (90) days from the
date the Demand Registration Request is given to the Company under Article 3
hereof (notwithstanding the provisions of Section 4(a)(i) to the contrary);
provided, however, that the Company shall not be permitted to give any such
Notice of Postponement and to so postpone the filing of the Registration
Statement more than once in any 365 day period; and provided, further, that in
the event of such postponement, ARC may withdraw the notice of Demand
Registration during the 60-day period following the date Notice of Postponement
is given by the Company and will thereafter continue to be entitled to one (1)
Demand Registration Request pursuant to Article 3 hereof.





                                    5 of 12
<PAGE>   39

                  (b) The Company shall pay all costs, fees and expenses in
connection with all Registration Statements filed pursuant to Article 2 or
Article 3 hereof including, without limitation, the Company's legal and
accounting fees, printing expenses, and blue sky fees and expenses; provided,
however, that ARC shall be solely responsible for the fees of any counsel
retained by ARC in connection with such registration and any transfer taxes or
underwriting discounts, commissions or fees applicable to the Registrable
Securities sold by ARC pursuant thereto.

                  (c) The Company will take all necessary action which may be
required in qualifying or registering the Registrable Securities included in a
Registration Statement for offering and sale under the securities or blue sky
laws of such states as are reasonably requested by the holders of such
securities, provided that the Company shall not be obligated to execute or file
any general consent to service of process or to qualify as a foreign corporation
to do business under the laws of any such jurisdiction.

                  (d) The Company shall cooperate with ARC to facilitate the
timely preparation and delivery of certificates representing Registrable
Securities to be sold (in such denominations and registered in such names as ARC
may request) and not bearing any legends restricting the transfer thereof under
the Securities Act, except as may be required by law.

                  (e) The Company shall cause all Registrable Securities to be
listed or accepted for listing or quotation on each securities exchange or
interdealer quotation system on which the Company's Common Stock then trades.

                  (f) The Company shall provide a CUSIP number for all
Registrable Securities covered by the Registration Statement.

                  (g) Otherwise use best efforts to comply with all applicable
provisions of the Securities Act, and rules and regulations of the Commission,
and make available to its security holders, as soon as reasonably practicable,
an earnings statement covering a period of at least twelve months which shall
satisfy the provisions of Section 11(a) of the Securities Act and Rule 158
thereunder.

         5. INDEMNIFICATION.

                  (a) The Company shall indemnify and hold harmless ARC, any
underwriter (as defined in the Act) for ARC and each person, if any, who
controls ARC or underwriter within the meaning of the Securities Act or the
Securities Exchange Act of 1934, as amended (the "1934




                                    6 of 12

other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereof) arise out of or are based upon any
of the following statements, omissions or violations (collectively a
"Violation"): (i) any untrue statement or alleged untrue statement of a material
fact contained in such Registration Statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements

conformity with written information furnished by such indemnitee expressly for
use in connection with such registration.

                  (b) ARC will indemnify and hold harmless the Company, each of

Section 5 of notice of the commencement of any action (including any
governmental action or investigation), such indemnified party will, if a claim
in respect thereof is to be made against any indemnifying party under this
Section 5, deliver to the indemnifying party a written notice of the
commencement thereof and the indemnifying party shall have the right to
participate in, and to the extent the




                                    7 of 12
<PAGE>   41

indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
5, but the omission so to deliver written notice to the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 5.

                  (d) To provide for just and equitable contribution, if (i) an
indemnified party makes a claim for indemnification pursuant to Section 5 but is
found in a final judicial determination, not subject to further appeal, that
such indemnification may not be enforced in such case, even though this
Agreement expressly provides for indemnification in such case, or (ii) any
indemnified or indemnifying party seeks contribution under the Securities Act,
the Exchange Act or otherwise, then the Company (including for this purpose any
contribution made by or on behalf of any director of the Company, any officer of
the Company who signed any such Registration Statement and any controlling
person of the Company), as one entity, and ARC (including for this purpose any
contribution by or on behalf of an indemnified party), as a second entity, shall
contribute to the losses, liabilities, claims, damages, and expenses whatsoever
to which any of them may be subject, on the basis of relevant equitable
considerations such as the relative fault of the Company and ARC in connection
with the facts which resulted in such losses, liabilities, claims, damages, and
expenses - The relative fault, in the case of an untrue statement, alleged
untrue statement, omission, or alleged omission, shall be determined by, among
other things, whether such statement, alleged statement, omission, or alleged
omission relates to information supplied by the Company or by ARC, and the
parties' relative intent, knowledge, access to information, and opportunity to
correct or prevent such statement, alleged statement, omission, or alleged
omission. The Company and ARC agree that it would be unjust and inequitable if
the respective obligations of the Company and ARC for contribution were
determined by pro rata or per capital allocation of the aggregate losses,
liabilities, claims, damages, and expenses (even if ARC and the other
indemnified parties were treated as one entity for such purpose) or by any other
method of allocation that does not reflect the equitable considerations referred
to in this Section 5. In no case shall ARC be responsible for a portion of the
contribution obligation in excess of its pro rata share based on the number of
shares of Common Stock owned (or which would be owned upon exercise of all
Registrable Securities) by it and included in such registration as compared to
the number of shares of Common Stock owned (or which would be owned upon
exercise of all Registrable Securities) by all holders and included in such
registration. No person guilty of a fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who is not guilty of such fraudulent misrepresentation. For purposes of
this Section 5, each person, if any, who controls any underwriter within the
meaning of Section 15 of the Act or Section 20(a) of the 1934 Act and each
officer, director, partner, employee and agent of ARC, underwriter or control
person shall have the same rights to contribution as ARC, underwriter




                                    8 of 12
<PAGE>   42

or control person and each person, if any, who controls the Company within the
meaning of Section 15 of the Act or Section 20(a) of the 1934 Act, each officer
of the Company who shall have signed any such Registration Statement, and each
director of the Company shall have the same rights to contribution as the
Company, subject in each case to the provisions of this Section 5. Anything in
this Section 5 to the contrary notwithstanding, no party shall be liable for
contribution with respect to the settlement of any claim or action effected
without its written consent, provided that such consent may not be unreasonably
withheld. This Section 5 is intended to supersede any right to contribution
under the Securities Act, the 1934 Act or otherwise.

                  (e) Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in. the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in this Agreement
shall control.

                  (f) The obligations of the Company and ARC under this Section
5 shall survive the completion of any offering of Registrable Securities in a
Registration Statement or the termination or suspension of this Agreement.

         6. 1934 ACT REGISTRATION; RULE 144 REPORTING. The Company covenants and
agrees that until such time as ARC no longer holds any Registrable Securities it
will:

                  (a) If required by law, use its best efforts to maintain an
effective Registration Statement (containing such information and documents as
the Commission shall specify) with respect to its Common Stock under Section 12
of the 1934 Act;

                  (b) Use its best efforts to make and keep public information
available, as those terms are understood and defined in Rule 144 under the Act,
even if the Company subsequently ceases to be subject to such reporting
requirements;

                  (c) Use its best efforts to file with the Commission in a
timely manner all reports and documents required of the Company under the Act
and the 1934 Act;

                  (d) Furnish to ARC promptly upon request (i) a written
statement by the Company as to its compliance with the reporting requirements of
Rule 144 and of the Act and the 1934 Act, (ii) a copy of the most recent annual
or quarterly report of the Company, and (iii) such other reports and documents
of the Company and other information in the possession of or reasonably
attainable by the Company as ARC may reasonably request in availing itself of
any rule or regulation of the Commission allowing ARC to sell any such
Registrable Securities without registration.




                                    9 of 12
<PAGE>   43

                  (e) The Company represents and warrants to ARC that any
information, document or report filed with the Commission in connection
therewith or any information so made public shall not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements contained therein
not misleading. The Company agrees to indemnify and hold harmless (or to the
extent the same is not enforceable, make contribution to) ARC, its partners,
officers, directors, employees and agents, each broker, dealer or underwriter
(within the meaning of the Act), if any, acting for ARC in connection with any
offering or sale of Registrable Securities or any person controlling (within the
meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act) ARC
and any such broker, dealer or underwriter from and against any and all losses,
claims, damages, liabilities or expenses (or actions in respect thereof) arising
out of or resulting from any breach of the foregoing representation or warranty,
all on terms and conditions comparable to those set forth in Section 5.

         7. ADDITIONAL TERMS.

                  (a) Neither the filing of a Registration Statement by the
Company pursuant to this Agreement nor the making of any request for
prospectuses by ARC shall impose upon ARC any obligation to sell ARC's
Registrable Securities.

                  (b) ARC, upon receipt of notice from the Company that an event
has occurred which requires a Post-Effective Amendment to the Registration
Statement or a supplement to the prospectus included therein, shall promptly
discontinue the sale of Registrable Securities until ARC receives a copy of a
supplemented or amended prospectus from the Company, which the Company shall
provide as soon as practicable after such notice.

                  (c) If the Company fails to keep the Registration Statement
referred to in Article 2 and Article 3 above continuously effective during the
requisite period, then the Company shall, promptly upon the request of ARC, use
its best efforts to update the Registration Statement or file a new registration
statement covering the Registrable Securities remaining unsold, subject to the
terms and provisions hereof.

                  (d) ARC agrees to provide the Company with any information or
undertakings reasonably requested by the Company in order for the Company to
include any appropriate information concerning ARC in the Registration Statement
or in order to promote compliance by the Company or ARC with the Securities Act.

Dear Sir:

Thank you for your fax of January 5, 1998. This Letter of Agreement sets forth
the material terms and conditions to be contained in a Manufacturing and
Distribution License Agreement (the "Master License") by, between and among
Viragen, Inc., ("Viragen"), Viragen Technology, Inc. ("VTI") and Southern Health
SDN.BHD ("Southern"). The parties agree to use their best efforts to complete
the Master License in good faith as soon as is reasonably practicable, execute
confidentiality agreements and agree to incorporate, among other things, the
terms and conditions set forth herein:

1. GRANT OF OPTION

Viragen, through its wholly owned subsidiary, VTI ("the Licensor") hereby agrees
to grant to Southern an exclusive Option to purchase the Master License for the
countries listed below (the "Option"). This Option shall become effective and in
full force and effect upon Southern's execution of this Letter of Agreement and
payment to the Licensor of the non-refundable Option amount of TWO HUNDRED
THOUSAND U.S. DOLLARS (US$200,000) which shall be received by the Licensor in
cleared funds no later than April 3, 1998. In the event the parties do not
consummate the Master License for any reason prior to the expiration date, the
Licensor shall forthwith refund one-half of the Option amount (ONE HUNDRED
THOUSAND U.S. DOLLARS) (US$100,000) and, in that event, no party hereto shall
have any claim upon the other party.

2. OPTION TERM AND TERRITORIES

The Option shall extend until September 30, 1998, 5:00 p.m., EST (the
"Expiration Date") and shall be exclusive as to the following countries:
Malaysia, Indonesia, Philippines, Thailand, Taiwan, Korea, Singapore, Australia
and New Zealand, hereinafter referred to as "the Territory".







<PAGE>   2

3. MASTER LICENSE FEE, TERM AND ROYALTY

Upon execution of the Master License and simultaneously therewith, Southern
shall pay in cleared funds to the Licensor the Master License Fee in the amount
of TWENTY MILLION U.S. DOLLARS (US$20,000,000) on or before the Option's
Expiration Date. Southern and/or its SUBLICENCEES shall additionally pay to the
Licensor a continuing Royalty of TWELVE PERCENT (12%) of gross revenues derived
by Southern or by or through its SUBLICENSEES from the sale of the Licensor's
natural alpha interferon product ("THE LICENSED PRODUCT"). Such Royalty shall be
paid to the Licensor by Southern and/or its SUBLICENSEES in U.S. dollars by wire
transfer by the fifteenth (15th) day of each month which amount shall represent
the preceding month's Royalty. Costs related to bank charges, wire transfers or
currency transactions and any taxes on Royalty payments shall be borne by
Southern which shall also stand liable for timely and accurate Royalty
collections from its SUBLICENSEES and payment thereof to the Licensor. The
Licensor shall have the right to access all books and records and appoint a
certified public accounting firm, or comparable, at the Licensor's expense, to
review Master Licensee's or subLicensee's books, records and inventory
facilities and equipment at any time during normal business hours by giving five
(5) days written notice. The term of the Master License shall extend for a
period of TWENTY-FIVE (25) YEARS from the date of its execution.

4. MASTER LICENSE KEY PROVISIONS AND TERM

OBLIGATIONS OF SOUTHERN. Among other provisions, the Master License shall
provide that Southern shall manufacture and distribute THE LICENSED PRODUCT in
accordance with all applicable laws, rules and regulations promulgated by the
appropriate regulatory agencies within the Territory in accordance with current
Good Manufacturing Practices (cGMP) as promulgated by the United Kingdom's
Medicine Control Agency ("MCA") or the United States' Food and Drug
Administration ("FDA") or comparable Tier I Country's regulatory agency.

Southern shall commence the building of at least one (1) manufacturing facility
at Southern's cost within two (2) years from the date of grant of the Master
License and such facility shall be built and operated in compliance with the
Licensor's specifications. Southern's manufacturing facility shall reach
commercial production levels within four (4) years from the date of execution of
the Master License. Southern agrees to follow all of the Licensor's
manufacturing procedures, including the Licensor's Standard Operating Practices
(SOPs), Protocols and Procedures. Southern shall cause to appear on or within
all advertising, instructional, informational, promotional or display material
either bearing or incorporating THE LICENSED PRODUCT, all required legal notices
pursuant to international copyright, trademark and patents laws and/or
regulatory requirements and/or as required from time to time by the Licensor.
Southern agrees that it shall, at its cost, register such patent, copyright,
trademark and/or service mark in the appropriate class, in the name of the
Licensor within the Territory.

Southern shall be responsible for arranging for and collecting human white blood
cells ("buffy coats") from qualified blood collection agencies within the
Territory according to the Licensor's specifications. Southern has been advised
that between 1 million to 2 million buffy coats (human white blood cell
collections or "leukocytes") are needed to support one (1) manufacturing
facility for THE LICENSED PRODUCT which is forecast to produce about
US$100,000,000 in annual gross retail




                                       2
<PAGE>   3
sales assuming a US $10 price per one million international units and comparable
manufacturing costs as experienced in Scotland and other commercial factors. The
cost of manufacturing one million international units can range between US $3.25
to $6.00. Additionally, Southern shall have the exclusive right to distribute
THE LICENSED PRODUCT as defined in the Master License, within its Territory in
accordance with the rules, laws and regulations established by each
jurisdiction.

Southern recognizes that THE LICENSED PRODUCT is technically classified as an
experimental drug until clinical trials have been completed and the drug
approved for commercialization by the regulatory authorities either in the
United Kingdom, United States or other Tier I country. Southern may elect to
obtain regulatory or governmental approval within its Territory for the use of
THE LICENSED PRODUCT for any disease state at Southern's cost including, costs
relating to clinical trials that it may wish to undertake in its own behalf
within the Territory.

Southern may sublicense to qualified third parties within the Territory in
accordance with the terms and conditions contained in the Master License which
shall require the reasonable consent of the Licensor, in which event Southern
shall retain any and all sublicense fees derived therefrom. Southern shall
maintain complete control of all of the Licensor's proprietary manufacturing
technology and shall not disclose or transfer to any subLicensee or any third
party whomsoever any of the Licensor's Standard Operating Practices, Protocols
and Procedures and Confidential Information. Southern will operate any and all
manufacturing facilities within its Territory in compliance with the Licensor's
specifications.

Southern shall be responsible for the costs of policing and enforcing the
licensed patents, trade secret rights and sublicense agreements in the
Territory, including the costs of any patent prosecution or license
registration.

OBLIGATIONS OF THE LICENSOR. The Licensor shall provide Southern with the
"know-how and show-how" as to the Licensed Patent Rights, the Licensed
Manufacturing Protocols, Procedures and Processes and all related Confidential
Information and Data (which shall include information relating to the
manufacturing equipment). The Licensor shall disclose its proprietary
manufacturing technology to Southern (which shall include the training of
Southern's designated manufacturing personnel on site) at no additional cost to
Southern. The Licensor shall also provide continuing consultative and support
services as reasonably required exclusively to Southern for a period of two (2)
years from the date of execution of the Master License at no additional cost to
Southern except travel, room and board expenses for the Licensor's related
personnel. Further, the Licensor shall provide to Southern all clinical trial
protocols which it may have developed from time to time for specific disease
states for testing THE LICENSED PRODUCT so that Southern may elect to execute
clinical trials within its Territory.

5. PROVIDING THE LICENSED PRODUCT TO SOUTHERN

The Licensor shall use its best efforts in order to obtain THE LICENSED PRODUCT
from its manufacturing facility in Edinburgh, Scotland, at the earliest
opportunity. Any obligation to supply THE LICENSED PRODUCT to Southern shall
terminate at such time as Southern's first manufacturing facility becomes
operational. In this regard, a separate agreement would necessarily be
negotiated between Southern and Viragen (Europe) Ltd., ("VERP"), which would
provide for a preferred




                                       3
<PAGE>   4

discounted price to Southern and would be subject to all laws, rules and
regulations of the United Kingdom. All Royalty payments arising from the sale of
THE LICENSED PRODUCT within the Territory from VERP-produced product will be
waived.

6. PROHIBITION AGAINST USE OF CORPORATE NAME, TRADENAMES, SERVICE MARKS AND
   COPYRIGHTS

Southern shall be prohibited from using the words "Viragen" and/or OMNIFERON in
any form and in any way.

7. INSURANCE AND INDEMNITY

Southern shall fully indemnify Viragen and the Licensor against any and all
claims, damages, and losses including attorney fees and other costs arising in
connection with or in relation to the Master License or any actions taken
pursuant to it, and shall obtain sufficient insurance in forms and amounts
acceptable to the Licensor and Viragen to cover such liabilities.

8. GOVERNING LAW

This agreement shall be governed by and interpreted in accordance with the laws
of the State of Florida, U.S.A., and shall be enforceable in Florida courts
except for provisions pertaining to conflicts of laws.

9. INVESTMENT BANKING FEE

The Licensor agrees to pay an investment banking fee of SIX PERCENT (6%) of the
