ITEM 1.  BUSINESS
 
INTRODUCTION
 
     Viragen, Inc., (the "Company" or "Viragen") was organized in December 1980
to engage in the research, development and manufacture of certain immunological
products for commercial application, particularly human leukocyte interferon,
for antiviral and therapeutic applications.
 
     Viragen, Inc. has five subsidiaries: Viragen (Europe), Ltd. ("VEL"),
Vira-Tech, Inc. ("Vira-Tech"), Viragen Technology, Inc. ("Viragen Technology"),
Viragen, U.S.A., Inc. ("VUSA") and Viragen Reagents, Inc. ("Viragen Reagents").
VEL is a majority-owned publicly traded subsidiary of which Viragen holds 70.3%
of the outstanding Common Stock. VEL (NASDAQ Small Cap: "VERP"), owns all of the
Common Stock of Viragen (Scotland) Limited, ("VSL"), and Viragen (Germany) GmbH.
Viragen, VEL, Vira-Tech, Viragen Technology, VUSA, Viragen Reagents and VSL are
hereinafter referred to collectively as the "Company," unless the context
otherwise requires.
 
     The Company's operations focus on the development of immunological products
developed from human blood derivatives. The Company's first product is a
multi-species, human leukocyte-derived alpha interferon ("Natural Interferon").
Natural Interferon is a protein substance that stimulates and modulates the
human immune system inhibiting malignant cell growth. In addition Natural
Interferon impedes the growth and propagation of various viruses. The Company's
second generation Natural Interferon, trade named Omniferon(TM), is currently
under development in its injectable form for the potential treatment of
Hepatitis B & C, Multiple Sclerosis ("MS"), HIV/AIDS and other autoimmune
disorders. Omniferon has not been approved by the United States Food and Drug
Administration ("FDA") nor the European Union ("EU") regulatory authorities, and
there can be no assurance that such approvals will be obtained at any time in
the future. In August 1998, the Company acquired a 10% equity interest, with an
option to acquire up to an 80% interest, in Inflammatics Inc. ("Inflammatics").
Inflammatics obtained a license to the rights to LeukoVAX(TM), a human blood
derived natural product for the treatment of rheumatoid arthritis. LeukoVAX is
currently in FDA, Phase I/II clinical trials. (The Company's Omniferon and
LeukoVAX products are sometime collectively referred to as the "Products" or
individually as a "Product.")
 
     The Company intends to obtain FDA and EU approvals for various uses of its
Omniferon and LeukoVAX products in the future. Such approvals are expected to
require several years of clinical trials and substantial additional funding. To
date, Viragen has not commercially distributed either product. Vira-Tech has
previously manufactured Alpha Leukoferon(TM), the Company's first generation
Natural Interferon product. This product was distributed for research purposes
pursuant to a limited Florida investigatory license and protocols program which
was discontinued in August 1995 (with the exception of certain limited
enrollments approved by the Florida HRS for humanitarian purposes under an
HIV/AIDS study protocol conducted at no charge to patients). Viragen is
concentrating its efforts on preparing, filing and processing its applications
and obtaining approvals for Omniferon, initially within the EU, and
subsequently, in the United States. The Company commenced preclinical studies
with Omniferon in March 1998 and plans to commence clinical trials during the
first calendar quarter of 1999.
 
     The Company has assembled an advisory committee consisting of scientists,
medical researchers and clinicians to assist the Company in its applications to
the FDA and the EU regulatory authorities.
 
     The Company's majority-owned subsidiary, Viragen (Europe) Ltd., acting
through its wholly-owned subsidiary VSL, entered into a License and
Manufacturing Agreement with The Common Services Agency of Scotland (the
"Agency"), an agency acting on behalf of the Scottish National Blood Transfusion
Service ("SNBTS"). Pursuant to such Licensing and Manufacturing Agreement,
SNBTS, on behalf of VSL, will assist in the manufacture of VSL's Omniferon
product for exclusive distribution within the EU and non-exclusively worldwide
in return for certain royalties and preferential access to the Product for
Scottish Agency patients at preferential prices. The Agency has committed to
assist in the manufacture of Omniferon in sufficient scale to accommodate the EU
clinical trials and, subsequently, for commercial sales in amounts to be agreed
upon by the parties. The Agency will also work with the Company in conducting
studies relevant to
                                        2
<PAGE>   4
 
Omniferon and cooperate with the Company to enable it to comply with the laws
and regulations of the EU in connection with production, clinical trials and
commercial distribution of Omniferon.
 
RECENT DEVELOPMENTS
 
     In furtherance of the Company's strategic plan to secure reliable and safe
sources of human white blood cells ("leukocytes" or "buffy coats") critical to
the production of both Omniferon and LeukoVAX, the Company has entered into a
series of strategic alliance and supply agreements with major worldwide
suppliers of blood products. During 1998, Viragen consummated agreements with
the American Red Cross and America's Blood Centers, which between them annually
collect a substantial majority of the U.S. blood supply, and a series of
agreements covering a majority of the blood supply in Germany, a major European
supplier.
 
     In July 1998, the Company and VUSA entered into a strategic alliance and
supply agreement with America's Blood Centers ("ABC") for the supply of human
white blood cells (leukocytes). ABC is a national network of non-profit,
independent community blood centers operating in 45 states. ABC members annually
collect in excess of 45% of the U.S. blood supply through its member blood
donation centers and mobile collection facilities. Under the terms of the ABC
Agreement, the Company was granted first and preferential access to all
leukocytes produced by ABC members who have elected to participate in the
program. The Company has agreed to pay a fixed cost per buffy coat provided
during the first two years of the ABC Agreement. Thereafter, the price may vary
based upon incremental costs incurred by participating ABC members.
 
     In August 1998, the Company and its majority owned subsidiary VUSA, Inc.
entered into a fifteen year Agreement with the American Red Cross ("ARC") for
the supply of human white blood cells. ARC collects approximately half of the
U.S. blood supply. The ARC Agreement provides for the Company's purchase of
buffy coats, consistent with agreed upon specifications, based on quarterly
forecasts provided by the Company. Buffy coats may be paid for in cash or Common
Stock of the Company at the option of ARC, with the valuation of shares paid
determined by the average closing price of the Company's shares for the five
days prior to the payment due date less a discount. The ARC Agreement further
contains an initial price per buffy coat modified by a volume discount pricing
schedule and rebate program, subject to periodic renegotiation. Upon execution
of the Agreement, ARC received a Warrant to purchase up to 500,000 shares of
Common Stock of the Company at exercise prices ranging from $5.50 to $11.00 per
share and 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 buffy coat purchases.
 
     In August 1998, the Company 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 has focused
on the development of therapeutic drugs for autoimmune disorders. Its lead
product is LeukoVAX, an immunomodulating therapy derived from leukocytes
currently in FDA Phase I/II clinical trials for rheumatoid arthritis.
 
     Under the terms of the Inflammatics Agreement, the Company made an initial
investment by purchasing Series A Convertible Preferred Stock of Inflammatics
for $1 million and warrants to purchase 200,000 shares of Common Stock of the
Company exercisable at $1.00 dollar per share, representing an initial 10%
equity interest in Inflammatics. The Company further obtained two options to
acquire up to an additional 70% equity position in Inflammatics through two
additional fundings to be made at the sole option of the Company. Additional
funding, if any, will be made based upon the Company's evaluation of LeukoVAX
clinical trial data and would be utilized to underwrite a FDA Phase III clinical
trial. As part of these options, the Company may issue up to 3 million shares of
its Common Stock and 300,000 additional warrants to purchase Common Stock of the
Company in exchange for additional Series A Convertible shares of Inflammatics
bringing the Company's total equity position in Inflammatics to 80%.
 
     On September 22, 1998 the Company entered into an Equity Line Financing
Agreement ("Equity Line Agreement") for a maximum offering amount of $20 million
over three years. Provisions of the Equity Line Agreement provide that the
Company, at its option, may "Put" shares of Common Stock to the investor,
following an effective Registration Statement, at a "Put Share Price" equal to
the lesser of (a) 87.5% of the
 
                                        3
<PAGE>   5
 
Market Price for such Put or (b) the difference of (i) the Market Price of such
Put minus (ii) $0.225 where the Market Price is defined as the lowest Closing
Bid Price during the 10 to 20 trading days (depending upon the size of the Put)
following each Put.
 
     The amount of Common Stock that may be Put in any 30 day period, is limited
to one half (1/2) of the aggregate daily reported trading volume in the
outstanding Common Stock reported during the 10 trading days preceding the Put
date. In addition, on each six month anniversary of the Subscription Agreement
date, the Company shall issue to the Subscriber a Purchase Warrant to purchase a
number of shares of Common Stock equal to 10% of the number of Put Shares issued
to the Subscriber during the preceding 6 calendar months. Each Purchase Warrant
shall be exercisable at 108% of the lowest closing bid price for the 10 trading
days immediately preceding each six month anniversary.
 
     In connection with the Equity Line Agreement, the Company also entered into
a Placement Agent Agreement which provides for a Cash Placement Fee on the gross
proceeds from the sale of the securities in any Put of: 7% on the first $5
million; 6% from $5 million to $10 million; and 3.5% for amounts in excess of
$10 million. If the Company were to Put securities for the entire $20 million
available under the Equity Line Agreement, the Cash Placement Fee would total 5%
of the total gross proceeds derived. In addition, the Placement Agent Agreement
provides for the issuance of Placement Agent Warrants to the Placement Agent
equal to: (i) 7%, 6% and 3.5%, respectively, on all shares issued in connection
with Put Shares at the same thresholds as the Cash Placement Fee, exercisable at
125% of the average Put Share Price of all Put Shares issued during the
preceding six calendar months; and (ii) a warrant to purchase a number of Common
Shares in the same percentages as above for which the subscriber has been issued
a Purchase Warrant, exercisable at 108% of the lowest closing bid price for the
10 trading days immediately preceding the applicable six month anniversary.
 
     As of the closing of the Equity Line Agreement, the Company had
approximately 1,900,000 shares of Common Stock available from total authorized
shares. Accordingly, to utilize the total funding available under the Equity
Line Agreement, the Company must obtain Stockholder approval to increase the
number of authorized shares in the Company. In addition, to comply with NASDAQ
National Market regulations regarding potential dilution limitations, the
Company intends to seek Shareholder's approval of the Equity Line Financing
Agreement.
 
OPERATIONS
 
     In March 1998, the Company commenced safety and preclinical trials in
Europe of its multi-species, human leukocyte-derived alpha interferon,
Omniferon. The Company anticipates the commencement of clinical trials in the
first calendar quarter of 1999.
 
     Viragen initially obtained approval for use of Alpha Leukoferon through
approved investigational protocols in 1983 under Florida Statute 402.36 (Cancer
Therapeutic Act), the predecessor to Florida Statute 499. In 1984, Florida
Statute 499.018 (the "499 Program"), was amended to include the Company's
protocols and Florida Statute 402.36 was repealed. In 1986, the Company received
approval from the Florida HRS under the 499 Program, to distribute Alpha
Leukoferon under specific investigative clinical study protocols through
hospitals, pharmacies and Florida licensed physicians for the treatment of
patients within the State of Florida. The Company subsequently received State of
Florida regulatory approval for the investigational use of Alpha Leukoferon in
the treatment of Multiple Sclerosis ("MS"), HIV/AIDS, AIDS Related Complex,
AIDS/Kaposi Sarcoma, 32 types of cancers, hepatitis and certain other viral
diseases. In December 1994, the Company discontinued enrollment of new patients
in its Multiple Sclerosis Study 499 Program. In August 1995, the Company
negotiated an agreement with the Florida Department of Health and Rehabilitative
Services ("HRS") which provided for the elimination of the enrollment of new
patients in its existing 499 Program (with the exception of certain limited
enrollments approved by the Florida HRS in 1996 for humanitarian purposes
including the Company's HIV/AIDS study conducted at no charge to patients), the
continued participation by previously enrolled patients in the 499 Program and
resolution of other issues. The Company believes, while there can be no
assurance as to future regulatory approvals, if any, the discontinuation of the
Company 499 Program will facilitate efforts in obtaining FDA and EU 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
 
                                        4
<PAGE>   6
 
such approvals. All other previously approved indications and protocols for the
use of Alpha Leukoferon are inactive.
 
     The Company will require additional financing to conduct and complete
clinical trials for the purpose of obtaining FDA and/or EU approvals for
Omniferon or LeukoVAX (if the Company exercises its right to acquire a
controlling interest in Inflammatics). Clinical testing toward FDA and/or EU
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
 
     The Company derives its Omniferon from human white cells (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 resultant composition. The first, as produced by the
Company, is multi-species natural, human leukocyte-derived alpha interferon
produced by cultivated human white blood cells, which are stimulated by the
introduction of a harmless agent. This process 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, recombinant interferon (alpha or beta), is a genetically engineered
synthetic interferon generally produced from a single human gene in bacterial
cells by recombinant DNA techniques ("Synthetic Interferon").
 
     Clinical studies suggest that there may be significant therapeutic
differences between the use of Natural Interferon and Synthetic Interferon. The
Company is advised that studies have found that treatment with Synthetic
Interferon in certain cases may cause an immunological response (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. The Company believes 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 Synthetic Interferon.
 
THE INTERFERON INDUSTRY
 
     Prior to 1985, Natural Interferon was the only type of interferon
available. Research institutions and other biomedical companies like the Company
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 FDA 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. See "Regulation"
and "Competition" below.
 
     After the emergence of recombinant alpha interferon, the medical
community's interest in Natural Interferon diminished due primarily to its
limited availability and its higher cost of production, and 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 FDA approval of
BetaSeron(TM), its recombinant beta interferon for the treatment of
relapsing/remitting MS. In 1996, Biogen, Inc. received FDA approval for
Avonex(TM) its recombinant beta interferon for relapsing/remitting MS. In 1997,
Teva Pharmaceuticals received FDA approval of its peptide chemical compound,
Copaxone(TM), for relapsing/remitting MS. In addition to the manufacturers of
Synthetic Interferons, a domestic manufacturer of natural interferon-alpha,
Interferon Sciences, Inc., received FDA
 
                                        5
<PAGE>   7
 
approval in 1989 to sell, in injectable form, Alferon(TM) their natural
interferon product for genital warts. They continue to conduct FDA sanctioned
clinical trials for additional indications.
 
APPLICATIONS OF INTERFERON
 
  Hepatitis C
 
     The hepatitis C virus (HCV) 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 and 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 the Company's scientific
staff and advisors, the Company believes that its Omniferon product may prove
efficacious in the treatment of this indication.
 
  Hepatitis B
 
     Approximately 45% of the world population live in areas with a high
prevalence of hepatitis B ("HBV") infection where the lifetime risk of infection
can exceed 60%. Most infections in these areas are acquired at birth or during
early childhood where 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 HBV are diagnosed annually with 2% to 10% of these patients
developing chronic infections, putting the patients at risk of progressive liver
disease possibly leading to cirrhosis and/or hepatocellar carcinoma.
 
     Synthetic Interferon alpha is the only FDA approved drug for HBV and has
been found to be an efficacious treatment in some cases. The Company believes
that Omniferon may also prove effective in the treatment of HBV.
 
  Multiple Sclerosis
 
     In 1988, following State of Florida regulatory approval for use of the
Company's product by HRS for the treatment of multiple sclerosis, the Company,
entered into a research agreement with the University of Miami School of
Medicine, Department of Neurology Multiple Sclerosis Center. Pursuant to the 499
Program this study was a patient funded, multi-phase clinical trial for the
treatment of multiple sclerosis with Alpha Leukoferon. The 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, the Company's interferon product provided favorable results in the
treatment of patients afflicted with relapsing/remitting, relapsing progressive
and chronic progressive MS.
 
     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 the Company's Alpha Leukoferon product in the treatment of various
types of multiple sclerosis. The abstract 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 the Company
appearing in the Journal of International Medical Research in 1996.
 
  Chronic Myelogenous Leukemia
 
     Chronic Myelogenous Leukemia ("CML") is one of a group of diseases called
myeloproliferative disorders and is usually recognized by a distinctive
cytogenetic abnormality, the Philadelphia Chromosome. The current treatment for
CML is high dose chemotheraphy 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, the Company received approval from the Florida HRS for an
HIV/AIDS treatment protocol using Alpha Leukoferon in injectable form. In
September 1993, the Company initiated distribution
                                        6

on a limited basis of its Product under this protocol. However, in December
1994, HRS informed the Company that no new patients may be enrolled under the
499 Program, including those patients with HIV/ AIDS, ARC and Kaposi's Sarcoma,
until the Company had satisfied HRS regarding compliance with FDA promulgated
current Good Manufacturing Practice ("cGMP") requirements. In July 1995, the
Company discontinued enrollment of new patients in its 499 Program and in August
1995, reached a settlement agreement with the Florida HRS which provided for the
elimination of the enrollment of new patients in its 499 Program (with the
possible exception of certain limited enrollments approved by the Florida HRS
for humanitarian purposes), the continued participation by previously enrolled
patients in the 499 Program and the resolution of other issues.
 
     In March 1996, the Company in collaboration with Biodoron, a Hollywood,
Florida based clinic, received approval from HRS under Florida's Investigational
Drug Program to conduct an investigational study in Florida of Viragen's natural
human alpha interferon product, Alpha Leukoferon, for the treatment of HIV/ AIDS
in hemophiliacs. The Company entered into an agreement with Quantum Health
Resources, Inc., ("Quantum") which provided to the Company $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, pursuant to which 35 patients enrolled to receive Alpha Leukoferon
for a minimum of six months in combination with a comprehensive HIV/AIDS
treatment program. As yet, the Company has not received the final results of the
study which includes the patient's follow-up period.
 
MANUFACTURE OF INTERFERON
 
     Human white blood cells (leukocytes) and a stimulating agent, raw materials
which are readily available to the Company, are needed to produce human
interferon. An FDA 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.
 
     The Company's Omniferon product is currently being manufactured in its
Scottish facility for use in ongoing animal safety and preclinical studies in
the EU commenced in March 1998, and for human clinical testing anticipated to
commence in the first quarter of calendar 1999. The Company's 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 developed by the Company, as well as enhanced methods
currently under development (see "Research and Development", below) could serve
to reduce the Company's costs of production and, therefore, the market price.
However, there can be no assurance that such new manufacturing technology will
enable the Company to achieve the level of manufacturing proficiency and product
improvement anticipated by management.
 
RESEARCH AND DEVELOPMENT
 
     The entire process of research, development and FDA and/or EU approvals, if
obtained, of a new pharmaceutical takes several years and requires substantial
funding. The Company is currently engaged in animal safety and preclinical
studies of Omniferon and, through its equity investment in Inflammatics, FDA
Phase I/II clinical trials of LeukoVAX. The completion of requisite clinical
studies for either Product prior to marketing approval is dependent upon
obtaining significant additional funding. The Company's present focus is the
continued research and development of Omniferon for the treatment of hepatitis B
and C, Multiple Sclerosis, CML, Herpes and HIV/AIDS.
 
     The Company has expended a substantial amount of time and resources towards
the research and development of improved cell stimulation and purification
techniques of its Omniferon Product. These processes are believed to enhance the
purity of the product while increasing production yields. It is believed that
efforts focused on increased production yields, if successful, would
significantly lower related costs of production, ultimately allowing a lower
more competitive sales price of the Product.
 
                                        7
<PAGE>   9
 
     In 1991, the Company, due to its then absence of available funds, suspended
its research and development activities. In 1993, following receipt of new
equity financing and the election of new management, the Company recommenced
limited research efforts focusing on improving production techniques. Following
receipt of additional funding from private placement offerings which were
completed in August and December 1994, respectively, research efforts and
related costs increased and can be expected to continue to increase as the
Company continues its development of Omniferon.
 
     Research and development costs totaled $3,866,267, $2,168,914, and
$1,503,434 for fiscal years ended June 30, 1998, 1997 and 1996, respectively.
 
ROYALTY AGREEMENT
 
     The Company and Medicore, a former affiliate of the Company, 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 further provided that royalties of approximately $108,000
previously accrued as payable to Medicore will be the final payment due under
the agreement.
 
     The Company recognized royalty expense of $11,901 for the year ended June
30, 1996.
 
PATENTS
 
     The Company believes its production techniques are unique and are capable
of yielding a superior quality product while reducing production costs which may
enable the Company, subject to regulatory approval, to offer Omniferon at a
price competitive with the recombinant interferons currently being marketed. The
Company intends to file patent applications relative to certain production
techniques currently under development. The Company has also submitted several
foreign patent applications relating to Natural Interferon for topical use,
several of which have been granted.
 
     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, the Company may have to negotiate license
agreements with such patent holders to use such processes and products. The
Company believes that it does not infringe upon any current patent.
 
     The validity and enforceability of a patent can be challenged by litigation
after its issuance and if the outcome of such litigation is adverse to 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. There can be no assurance that patents
obtained in the future will be of substantial protection or commercial benefit
to the Company. (See "Competition" below).
 
REGULATION
 
  United States and European Union
 
     The Company's activities and the 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 EU member nations. The
manufacturing, advertising and sale of biologic substances and pharmaceutical
products is regulated by, and requires the approval of, the FDA, EU, state and
local agencies. The Company followed strict production and distribution
procedures under State of Florida HRS guidelines relating to its limited
 
                                        8
<PAGE>   10
 
distribution of its Alpha Leukoferon within the State of Florida. The FDA has
established mandatory procedures and standards which apply to the clinical
testing, marketing and manufacture of the Products. Obtaining FDA and/or EU
approval for commercialization of any new product can take significant time and
capital since it involves extensive testing procedures and often lengthy
clinical trials including the measurement of product safety, toxicity, and
efficacy, if any, under specific protocols. The process of obtaining FDA and/or
EU regulatory approval initially includes extensive animal testing to
demonstrate product safety and preferred dosages. Subsequent human tests are
then undertaken to show the same and to document such findings as effectiveness,
toxicity and side effects. Biostatistical analysis of data is then gathered in
such studies, followed by the submission of all information and data to the
regulatory authorities.
 
     At the present time, the Company is in preclinical studies of its Omniferon
product in the EU with no pending clinical trial application relative to
Omniferon before the EU regulatory authorities or the FDA for the treatment of
any disease indications, although the Company intends to commence clinical
trials in the EU during the first calendar quarter of 1999 and eventually submit
an Investigative New Drug Application to the FDA. For these purposes, the
Company has assembled a Clinical Advisory Committee comprised of scientists,
medical researchers and clinicians who will act in an advisory capacity in order
to assist the Company in developing the medical, scientific and clinical aspects
in support of the Company's anticipated applications to be filed initially with
the EU and eventually FDA regulatory authorities.
 
     In the United States and Europe, 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 that a product demonstrated potential
effectiveness and has an acceptable safety profile, Phase III trials are
undertaken 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 product can often take five
years or longer (unless accelerated in certain instances for life-threatening
diseases) and involves the utilization 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 FDA 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
such laws as apply in those countries. The Company must comply with all FDA
rules and regulations as well as those of the country to which the Company
intends to ship the Product before it would be permitted to export crude or
finished interferon products outside the United States.
 
  License and Manufacturing Agreement
 
     In certain instances, EU regulations may require less stringent preclinical
studies for naturally occurring substances such as the Company's Omniferon
product than for genetically engineered products. Accordingly, while there can
be no assurance, the Company expects to possibly receive a more expeditious
review of the various EU processes and clinical trials prerequisite to market
approval in the EU.
 
     In July 1995, Viragen (Scotland) Limited ("VSL"), a company incorporated
under the laws of 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 employing the Company's processes. Securing a sufficient
qualified source of blood-derived raw materials within the EU
 
                                        9
<PAGE>   11
 
was considered critical to enable the Company to conduct EU clinical trials as
well as providing a sufficient source of raw materials necessary for subsequent
commercial manufacturing.
 
     During fiscal 1998, the Company was notified that due to concerns over the
possible presence of New Varient Creutzfeld-Jacob disease ("nvCJD") 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 the Company's planned clinical trials or
potential commercial production until the European regulatory authorities were
satisfied that the risk of nvCJD contamination had been minimized. The Company
intends to utilize leukocytes produced in Germany under its German Red Cross
contractual arrangements as well as other approved sources to continue with its
planned clinical trials and possibly the commencement of commercial scale
production if needed.
 
     Prior to the commencement of clinical trials, the Company's Scottish
manufacturing facility must be licensed by EU regulatory authorities to conduct
such trials. The Company has engaged professionally recognized consultants
familiar with the EU regulatory process to assist in the manufacturing and
product submissions prerequisite to EU approvals. In addition, the SNBTS has a
full-time regulatory department that has obtained approval in the EU of numerous
EU blood-derived products. The SNBTS will provide its best efforts, working in
conjunction with the Company, to obtain a manufacturing license and subsequent
product approvals at the conclusion of the EU clinical studies. At such time as
a manufacturing license is obtained for Omniferon, the Company intends to seek
FDA manufacturing approval of the Scottish manufacturing facility. There can be
no assurance that the EU regulatory authorities will approve the manufacturing
or permit clinical testing and distribution of Omniferon within the EU, or that
the FDA will license or approve the Scottish manufacturing facility or the
Company's Product for clinical trials and subsequent distribution in the United
States.
 
     VSL has been organized by the Company to manufacture and distribute
Omniferon and related products in the EU and other countries outside the United
States. Through Viragen Technology Inc., Viragen has transferred patent and
proprietary rights associated with the production of its Product and related
technology to VSL under a grant of license. VSL has provided the SNBTS 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 EU. SNBTS has committed to participate with the Company in the manufacture
of Omniferon in sufficient scale to accommodate the EU clinical trials and also
to conduct certain studies relevant to the Product and cooperate with VSL and
the Company in complying with the laws and regulations of the EU in connection
with the production of Omniferon.
 
     Pursuant to the License and Manufacturing Agreement, VSL, VEL and the
Company are providing SNBTS with full access to the proprietary technology and
specialized equipment, providing suitable training as needed to SNBTS personnel
and defraying all costs associated with securing permits and regulatory
approvals, augmenting SNBTS facilities, if necessary, to participate in the
manufacture of Omniferon and securing documentation substantiating compliance
with EU regulatory requirements. SNBTS will receive compensation for Product
manufactured for use in clinical trials in the EU, for Product manufactured for
sales prior to obtaining new drug application approval, and for sales following
such approval, at varying percentages in relation to costs. Products
manufactured and utilized 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. The Company has further agreed to compensate
SNBTS for the provision of process documentation for further production
facilities established by the Company.
 
     The term of the License and Manufacturing Agreement is for a five-year
period with two additional five-year extension terms at the option of VSL. The
Agreement also contains provisions protecting the proprietary rights of VSL and
the Company and the preclusion of certain competitive activities by SNBTS.
 
     As a result of the completion of the private placements undertaken in March
1996, VEL received net proceeds of $5,102,000 which is being used for (i) the
leasing and improvement of production facilities in Edinburgh, Scotland,
utilized in the manufacture of Omniferon; (ii) the purchase of equipment for use
of VSL's Scottish facilities; (iii) the payment of royalties to Viragen
Technology, commenced in calendar 1997
                                       10

and (iv) for working capital purposes. VSL is currently engaged in animal safety
and preclinical studies and will require significant additional financing to
complete clinical trials required to obtain EU regulatory approval for
distribution of the Product. Clinical testing toward EU approval is an expensive
process, which is expected to take several years to accomplish with no assurance
that such approval will eventually be obtained.
 
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, viral infections, MS, HIV/IDS, KS
and hepatitis.
 
     In addition to the manufacturers of Synthetic Interferons, Interferon
Sciences, Inc. a domestic manufacturer of Natural Interferon received FDA
approval in 1989 to sell, in injectable form, their natural interferon product
for genital warts. They continue to conduct FDA sanctioned clinical trials for
additional indications.
 
     The Company believes 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. The
Company's ability to develop products, complete clinical studies and obtain
governmental approvals in the past had been hampered by a lack of adequate
capital. The Company is not presently a competitive factor in revenue
participation in the biopharmaceutical industry.
 
EMPLOYEES
 
     As of September 21, 1998, the Company has 41 employees, of which 23 are
Research and Development and Quality Assurance/Quality Control personnel. The
remaining 18 employees are management, regulatory and/or administrative.
 
ITEM 2.  PROPERTIES
 
     In November 1996, the Company entered into a ten year lease for 14,800
square feet in Plantation, Florida. This location houses the Company's
administrative and executive offices as well as potential laboratory expansion
space. The lease contains an option for up to two additional five year terms.
Base lease payments on the facility total $15,700 per month. The Company's
administrative offices are located at 865 SW. 78th Avenue, Suite 100,
Plantation, Florida 33324; phone (954) 233-8746.
 
     The Company owns a 14,000 square foot building in Hialeah, Florida. This
facility includes a laboratory for biomedical research and development
activities. The Company refinanced its building through a $600,000 borrowing
with a Florida bank under a five year note and mortgage in August 1991. The loan
was reduced in equal monthly principal payments of $2,500 with interest at 2% in
excess of the prime rate. The mortgage was on the land, building and
improvements, equipment and fixtures used in connection with the realty. A
balloon payment of $450,000, due in August 1996 was paid-in-full at maturity.
 
     In November 1996, the Company, through VSL, entered into a five year lease
agreement in a biotechnology park in the Edinburgh area of Scotland. This
facility, comprised of approximately 12,000 sq. ft., contains the Company's
European laboratory and production facilities. This location will augment other
productive assets located within the SNBTS facility, which are available to the
Company under the Scottish
                                       11
<PAGE>   13
 
Agreement. The annual base lease rate for the facility is 71,700 UK pounds or
approximately US$120,000 plus adjustment for common area maintenance charges.
The Company has the right to renew the lease for four additional five year
terms.
 
     The Company considers that its properties are generally in good condition,
well-maintained and generally suitable and adequate to carry on the Company's
business. The Company further believes that it maintains sufficient insurance
coverage on the Company's real and personal property.
 
ITEM 3.  LEGAL PROCEEDINGS
 
     In May 1997, the Company, through its majority owned subsidiary Viragen
(Europe) Ltd. (formerly Sector Associates, Ltd. -- "Sector"), was named as a
defendant in an action brought in the United States Bankruptcy Court, Southern
District of Florida by the bankruptcy trustee for Florida West Airlines, Inc.
The suit alleged that during the period from December 1993 to May 1994, prior to
the Company's reverse acquisition of Sector, Sector received preferential
transfers of approximately $2.1 million. The Company denied that such transfers
were preferential and vigorously defended the claims. This litigation was
settled for $25,000 in July 1998, which amount the Company believed represented
less than its anticipated costs of further litigation.
 
     In October 1997, the Company, 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
stockholder of the Company 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. The Company 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 the Company 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 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 the Company's Motion to Dismiss the complaint. Subsequently, the
plaintiff filed an Amended Complaint alleging similar claims and seeking
comparable remedies. In April 1998, the Company filed a Motion to Dismiss
plaintiff's amended complaint which was denied by the Court. The Company has
filed its answer denying the plaintiff's claims and discovery is proceeding.
 
     The Company denies the allegations of the complaint and, while it cannot
predict the ultimate outcome, it intends to vigorously defend this action.
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     No matter was submitted during the fourth quarter of the fiscal year to a
vote of security holders through the solicitation of proxies or otherwise.

     As of September 21, 1998 there were approximately 2,700 stockholders of
record. At that date the closing price of the Common Stock was $1.50 per share.
 
     The Company has not paid any dividends on its Common Stock since its
incorporation in 1980. Since the Company had been in the development stage, has
experienced losses since inception (see Item 7, "Management's Discussion and
Analysis of Financial Condition and Results of Operations"), has significant
capital requirements in the future and presently intends to retain future
earnings, if any, to finance the expansion of its business, it is not
anticipated that any cash dividends will be paid in the foreseeable future.
Future dividend policy will depend on the Company's earnings, if any, capital
requirements, expansion plans, financial condition and other relevant factors.

     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 Company's financial condition or results of operations.
 
     The Company's future success depends in part upon its intellectual
property, including patents, trade secrets, know-how and continuing
technological innovation. There can be no assurance that the steps taken by the
Company to protect its intellectual property will be adequate to prevent
misappropriation or that others will not develop competitive technologies or
products. There can be no assurance that any current or future patent, if any,
owned by the Company will not be invalidated, circumvented or challenged, that
the rights granted thereunder will provide competitive advantages to the Company
or that any of the Company's future patent applications will be issued with the
scope of the claims sought by the Company, if at all. Furthermore, there can be
no assurance that others will not develop technologies that are similar or
superior to the Company's technology, duplicate the Company's technology or
design around the patents, if any, owned by the Company.
 
     The Company has incurred operational losses and operated with a negative
cash flows since its inception in December 1980. Losses have totaled $7,856,136,
$4,775,245, and $4,672,271 for the years ended June 30, 1998, 1997 and 1996,
respectively.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Working capital totaled approximately $7,842,000 on June 30, 1998, a
decrease of approximately $21,489,000 from the previous year end balance. This
decrease was due in part to the exchange of a Convertible Preferred Stock series
for a note payable totaling $9,720,241 which was paid in full during the year,
as well as additional cash redemptions, refunds and dividends in certain other
convertible preferred stock
 
                                       14
<PAGE>   16
 
series totaling approximately $8,967,000, additions to property, plant and
equipment of approximately $1,623,000, and operational losses of $7,856,136
being offset by the proceeds of two Convertible Stock Offerings (Series H and
Series I) during the period.
 
     Commencing in June 1996 through February 1997, the Company completed four
Convertible Preferred Stock issuances with gross proceeds of $40,000,000: Series
B- $15,000,000; Series C-$5,000,000; Series D-$15,000,000 and Series
E-$5,000,000.
 
     During July and August of 1997, the terms of the four series of preferred
stock were modified in order to limit or otherwise restrict the timing or number
of conversions of the preferred stock into Common Stock over a given period.
This restructuring was initiated in order to mitigate concerns of the Company
and the investment community concerning the "overhang" on the Company's Common
Stock represented by the potential conversion of these outstanding series of
preferred stock under their original terms.
 
     In July 1997, the then remaining unconverted Series B Preferred Stock was
exchanged for a 10% Promissory Note in the amount of $9,720,241. The Note
provided for principal and interest payments over nine monthly installments
commencing in October 1997. The Note could be prepaid without penalty and was
not convertible into Common Stock of the Company. The Note was paid off during
fiscal 1998. Also in July 1997, the holders of the Series C Preferred Stock
agreed to modify their conversion price and limit conversions of their then
remaining 974 shares ($1,000 face value per share) over a minimum two month
period. The modified conversion price was the lower of (i) $2.20 per share or
(ii) the average closing price of the Company's Common Stock over the five day
period ending the day prior to the notice of conversion. The remaining shares of
Series C Preferred Stock were completely converted into Common Stock in December
1997.
 
     In September 1997, the Company concluded two Exchange Agreements whereby
the terms of the Series D Preferred Stock and Series E Preferred Stock were
modified. The then remaining unconverted preferred shares ($1,000 face value per
share) of Series D (7,950 Preferred Shares) were exchanged for a like number of
Series F Preferred Shares, and Series E (4,000 Preferred Shares) was exchanged
for a like number of Series G Preferred Shares.
 
     The Series F Preferred Stock provided for a limitation on the holder
limiting conversion during any two-week period of $800,000 including accrued and
unpaid dividends. The terms also provided the Company with a cash-out option at
the face amount being converted plus 12% if the Conversion Price is below $2.00
per share. In consideration for the holder of the Series D Preferred Stock
agreeing to a limitation on the speed of future conversion, the Company agreed
to increase the dividend rate from 6% for the Series D Preferred Stock to 10%
for the Series F Preferred Stock. During the third fiscal quarter of 1998, the
remaining Series F Preferred Stock outstanding totalling 4,200 shares
($4,200,000), was converted (1,750 shares) or redeemed through cash payments
(2,450 shares).
 
     The terms of the Series G Preferred Stock provided that commencing in
September 1997, the holder was limited to converting 667 shares ($667,000) per
month over a 6-month period. The provisions further provided that the Company
would be required to redeem 667 shares ($667,000) per month less the number of
Series G Preferred Stock converted during the proceeding calendar month. In
addition, the holder was restricted from converting into Common Stock if the
market price of the Company's Common Stock was less than $2.50, subject to
adjustment, at the date of the conversion notice. In consideration for the
restrictions on conversion, the Company agreed to increase the dividend rate
from 5% for the Series E Preferred Stock to 10% for the Series G Preferred
Stock. No other material changes were made in the substantive terms from the
previously issued Series E Preferred Stock. The final redemption of the Series G
Preferred Stock occurred in February 1998.
 
     During the third and fourth fiscal quarters of 1998, the Company closed $7
million in financings replacing a portion of the funds used to redeem previous
preferred stock issuances. In February 1998, the Company received net proceeds
of approximately $4,625,000 from the sale of 500 shares of its Series H
Convertible Preferred Stock (the "Series H Preferred Stock") with an aggregate
stated value of $5 million. In April 1998, the Company received net proceeds of
approximately $1,840,000 from the sale of 200 shares of its Series I
 
                                       15
<PAGE>   17
 
Convertible Preferred Stock (the "Series I Preferred Stock"). The Company
incorporated certain restrictions as part of the Series H and Series I Preferred
Stock designations which the Company believes will facilitate a more orderly
market relative to the underlying shares of its Common Stock. The Series H and
Series I Preferred Stock bear no dividends although, upon liquidation or
conversion, an 8% accretion factor will be included in the calculation for
purposes of determining the liquidation and conversion amount.
 
     Both the Series H and Series I Preferred Stock issuances were not
convertible until six months following the closing date for the Series H
transaction. The conversion price is the lower of (i) the fixed conversion
price, which will be equal to the lower of the average closing price per share
for the 5 days prior to closing ($2.15 per share) or the market price of Common
Stock six months following the final closing date ($1.94 per share), and (ii)
the variable conversion price which will be equal to 82% of the market price at
the date of conversion. The Company 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 is further limited to a maximum of 15% of the
aggregate 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. As of September 21, 1998 $1,045,000 in principal of the
Series H and Series I Preferred Stock issuances had been presented to the
Company for conversion into 1,064,486 shares of Common Stock.
 
     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 (i)
remain qualified for trading; (ii) convert preferred shares to common stock; and
(iii) maintain an effective registration statement. Upon the occurrence of an
event of default, the holders of the Series H Preferred Stock 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 the Company'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.
 
     In April 1998, the Company entered into an option agreement with Southern
Health SDN.DHD ("Southern") a private Malaysian/Australian-based healthcare
investment group. The option agreement provides Southern the right to acquire,
through September 30, 1998, subsequently extended to December 31, 1998, an
exclusive private-label Manufacturing and Distribution License for the Company's
proprietary production process in exchange for an initial cash licensing fee of
$20 million and a continuing royalty of 12% of Southern's related revenues.
Southern has paid the Company a $200,000 option fee, $100,000 of which is non
refundable and intended to defer the costs of related due diligence with the
remaining $100,000 refundable if the Company elects not to proceed with this
transaction. There can be no assurance that this transaction will ultimately be
successfully concluded. Also, the Company believes that this transaction may be
negatively affected by instability in Asian financial markets.
 
     While subject to significant limitation, the Company at June 30, 1998 has
available approximately $26,424,000 in net tax operating loss carryforwards
expiring between 1999 and 2013, which may be used to offset taxable income, if
any, during those periods. The Company's ability to generate revenues during
future periods is dependent upon obtaining regulatory approvals of its Omniferon
and/or LeukoVAX products. As the Company cannot be assured as to its ultimate
success in obtaining the necessary regulatory approvals, the Company is unable
to conclude that realization of benefits from its deferred tax assets is more
likely than not, as prescribed by SFAS 109. Accordingly, the Company has
recognized a valuation allowance to offset 100% of the deferred tax assets
related to these carryforwards.
 
     On September 22, 1998 the Company entered into an Equity Line Financing
Agreement ("Equity Line Agreement") for a maximum offering amount of $20 million
over three years. Provisions of the Equity Line Agreement provide that the
Company, at its option, may ("Put") shares of Common Stock to the investor,
following an effective Registration Statement, at a "Put Share Price" equal to
the lesser of (a) 87.5% of the
 
                                       16
<PAGE>   18
 
Market Price for such Put or (b) the difference of (i) the Market Price of such
Put minus (ii) $0.225 where the Market Price is defined as the lowest Closing
Bid Price during the 10 to 20 trading days (depending upon the size of the Put)
following each Put.
 
     The amount of Common Stock that may be Put in any 30 day period, is limited
to one half (1/2) of the aggregate daily reported trading volume in the
outstanding Common Stock reported during the 10 trading days preceding the Put
date. In addition, on each six month anniversary of the Subscription Agreement
date, the Company shall issue to the Subscriber a Purchase Warrant to purchase a
number of shares of Common Stock equal to 10% of the number of Put Shares issued
to the Subscriber during the preceding 6 calendar months. Each Purchase Warrant
shall be exercisable at 108% of the lowest closing bid price for the 10 trading
days immediately preceding each six month anniversary.
 
     In connection with the Equity Line Agreement, the Company also entered into
a Placement Agent Agreement which provides for a Cash Placement Fee on the gross
proceeds from the sale of the securities in any Put of: 7% on the first $5
million; 6% from $5 million to $10 million; and 3.5% for amounts in excess of
$10 million. If the Company were to Put securities for the entire $20 million
available under the Equity Line Agreement, the Cash Placement Fee would total 5%
of the total gross proceeds derived. In addition, the Placement Agent Agreement
provides for the issuance of Placement Agent Warrants to the Placement Agent
equal to: (i) 7%, 6% and 3.5%, respectively, on all shares issued in connection
with Put Shares at the same thresholds as the Cash Placement Fee, exercisable at
125% of the average Put Share Price of all Put Shares issued during the
preceding six calendar months; and (ii) a warrant to purchase a number of Common
Shares in the same percentages as above for which the subscriber has been issued
a Purchase Warrant, exercisable at 108% of the lowest closing bid price for the
10 trading days immediately preceding the applicable six month anniversary.
 
     As of the closing of the Equity Line Agreement, the Company had
approximately 1,900,000 shares of Common Stock available from total authorized
shares. Accordingly, to utilize the total funding available under the Equity
Line Agreement, the Company must obtain Stockholder approval to increase the
number of authorized shares in the Company. In addition, to comply with NASDAQ
National Market regulations regarding potential dilution limitations, the
Company intends to seek Shareholder's approval of the Equity Line Financing
Agreement.
 
     Management believes that the Company's Omniferon product currently under
development can be manufactured in sufficient quantity and will be priced at a
level to offer patients an attractive alternative treatment to the Synthetic
Interferons currently being marketed. Management further believes that working
capital currently on hand and available under its Equity Line Agreement will
provide the Company with the funds necessary for at least the next fiscal year
to continue its current level of operations, focused on current development and
production scale-up projects relating to Omniferon in the Company's laboratory
and manufacturing facility in Scotland, including EU preclinical trials
currently being conducted and the commencement of clinical trials. Clinical
trials in the EU are scheduled to commence in the first quarter of calendar
1999.
 
     Additional funding will be required to complete the clinical trial process
relating to Omniferon both in the EU and domestically prior to receiving
regulatory approval to market the Product. Anticipated funding requirements in
the EU include: preclinical, Phase I and Phase II trials -- $1.5-$2.0 million
and Phase III studies -- $12-$14 million. In addition, anticipated funding
requirements for U.S. operations include: the establishment of domestic
manufacturing capacity -- $6 million; joint research and development projects --
$4 million and commencement of domestic preclinical Phase I and Phase II studies
- -- $1.5-$2.0 million. Funding will also be utilized for continued product
development research, general working capital purposes including administrative
support functions and the possible equity investments in businesses
complementary to the Company's operations.
 
     In August 1998, the Company 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 has
focussed on the development of therapeutic drugs for autoimmune disorders. Its
lead product is LeukoVAX, an immunomodilating white blood cell (leukocyte)
preparation currently in FDA Phase I/II clinical trials for rheumatoid
arthritis.
 
                                       17
<PAGE>   19
 
     Under the terms of the Inflammatics Agreement, the Company made an initial
investment in the form of Series A Convertible Preferred Stock of Inflammatics
for $1 million and warrants to purchase 200,000 shares of the Company's Common
Stock at $1.00 dollar per share. The Company further obtained two options to
acquire an additional 70% equity position in Inflammatics through two additional
fundings to be made at the sole option of the Company. Additional funding, if
any, will be made based upon the evaluation of LeukoVAX clinical trial data and
will be utilized to underwrite a Phase III clinical trial. The Agreement also
provides for the Company to issue up to 3 million shares of its Common Stock and
warrants to acquire 300,000 shares at the then current market price of the
Company's Common Stock in exchange for additional Series A Convertible shares of
Inflammatics if all funding phases are completed.
 
     The Company commenced pre-clinical trials with Omniferon in the EU in March
1998 and intends to commence clinical trials in the EU during the first calendar
quarter of 1999 and eventually submit an Investigational New Drug Application to
the U.S. FDA. Such approvals cannot be assured and are subject to the successful
completion of clinical trials and the Company's ability to raise significant
additional investment capital to fund the completion of such trials.
 
RESULTS OF OPERATIONS
 
     No sales revenue or related costs of sales were recognized for the fiscal
years ended June 30, 1998 or 1997, respectively. The termination of sales
revenues was due to patients previously enrolled under the Company's State of
Florida HRS 499 program, the Company's only sources of sales revenue, completing
their course of treatments in fiscal 1996. The Company discontinued enrollment
of new patients in its 499 Program (with the exception of certain limited
enrollments approved by HRS for humanitarian purposes including an HIV/AIDS
study conducted at no charge to patients) and all revenues under this program
ceased in March 1996. The Company has no other source of revenues from the sale
of its products unless or until it receives the necessary regulatory approvals
from the U.S. Food and Drug Administration and/or comparable European
authorities. At the present time, the Company has no pending application
relative to Omniferon, the Company's multi-species, natural human
leukocyte-derived alpha interferon, before the EU regulatory authorities or the
FDA for the treatment of any disease indications, although the Company commenced
pre-clinical trials in the EU in March 1998 and intends to commence clinical
trials in the EU during the first calendar quarter of 1999 and eventually submit
an Investigational New Drug Application to the FDA. Such approvals cannot be
assured and are subject to the successful completion of clinical trials and the
Company's ability to raise significant additional investment capital to fund the
completion of such trials.
 
1998 COMPARED TO 1997
 
     Interest and other income of $1,143,112 represented earnings on invested
cash balances during the year and reflects a 19% decline from the previous
fiscal year. As the Company's cash balances have declined significantly from the
previous year, due primarily to cash redemptions on Convertible Preferred Stock
issuances and operational losses (see "Liquidity and Capital Resources" above)
this trend is expected to continue into the next fiscal year.
 
     Research and development costs totaled $3,866,267, for fiscal 1998 compared
to $2,168,914 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 the Company's manufacturing
technology in its 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 SNBTS 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 the Company's Florida and Scottish facilities.
 
     Selling, general and administrative expenses totaled $5,429,345 for fiscal
1998, reflecting an increase of $1,470,677 (37%) over the preceding year. This
increase included increases in administrative salaries and related taxes of
$599,400, due primarily to the addition of administrative staff in the Company's
Florida facility and domestic salary increases. The Company also recognized
increases in rent expense commencing in
 
                                       18
<PAGE>   20
 
August 1997 related to its new administrative facility in Plantation, Florida
and the expansion of leased space in its Scottish manufacturing facility. Rent
expense for the Company's 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. The Company also recognized $109,900 in bad debt expense
attributable to a Director loan with related accrued interest (see Item 13
"Certain Relationships and Related Transactions"). These increases were offset
by compensation expense in the prior year of $396,500 attributable to the
issuance of options not incurred in fiscal 1998 and a loss settlement in the
prior year of $250,400. The Company has also experienced increased travel costs
attributable to administrative support functions related to the establishment of
the Company's Scottish facility.
 
     Depreciation expense increased to $506,934, compared with $281,920 for the
preceding year. This increase was attributable primarily to the acquisition and
commencement of utilization of laboratory equipment in the Company's Scottish
laboratory and manufacturing facilities during fiscal 1997 and fiscal 1998. The
balance of the increase between the periods was primarily due to the utilization
of additional laboratory and research equipment in the Company's Florida
laboratory facility acquired during the same period. Depreciation expense will
continue to increase over comparable periods of the preceding year as the
Company continues its technology transfer and process development and scale-up
projects related to its Omniferon product and enters its clinical trial phases
scheduled to commence in the first quarter of calendar 1999.
 
     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 Company's Series B Convertible Stock then outstanding. This
Note was paid-in-full in April 1998. See "Liquidity and Capital Resources"
above.
 
1997 COMPARED TO 1996
 
     Interest and other income, which totaled $1,404,000 for fiscal 1997,
reflected a sharp increase over the prior year. This increase was attributable
to interest income earned on the net proceeds of a series of Convertible
Preferred Stock Offerings made during June 1996 and fiscal 1997. See "Liquidity
and Capital Resources" above.
 
     Research and development costs totaled $2,168,914 during the year compared
to $1,503,434 for fiscal 1996. This increase of $665,480 (44%) reflects an
overall increase in research activities and was primarily attributable to an
increase in laboratory supplies expenses of approximately $326,000, an increase
in fees paid to SNBTS relating to contracted reimbursements of $71,000,
increased travel expenses associated with the transfer of technology and process
development between the Company's Florida and Scottish facilities of $120,000,
an increase in research related consulting fees and increased salaries and
related taxes for laboratory personnel.
 
     Selling general and administrative expenses totaled $3,938,323 in fiscal
1997, an overall increase of approximately $438,000 from the prior year. This
increase reflects the net of changes in numerous components in general and
administrative expense items. Fiscal 1997 includes an increase in administrative
salaries and related taxes of approximately $351,500 due to the addition of
administrative staff in the Company's Scottish laboratory and manufacturing
facility, increased administrative staff in the Company's Miami facility and
domestic salary increases. During fiscal 1997, the Company also recognized
compensation expense of $450,000 associated with options granted during the
period compared to $426,000 in the previous year and recognized $288,000 in
expenses associated with the settlement, for treasury stock, of a potential
litigation claim.
 
     The Company also recognized increases in insurance expenses associated with
employee related insurance coverage and increased liability coverages of
$128,00, increased travel related costs of $109,000, primarily attributable to
administrative support related to the establishment of the Company's Scottish
facility, increased building and equipment leasing costs of $105,000 and
additional fees associated with the
                                       19
<PAGE>   21
 
Company's listing on the NASDAQ National Market of approximately $73,000. These
increases were offset by the reduction in officer loans forgiven in the prior
year of $282,000 and a loss recognized on the valuation of the Company's Florida
laboratory facilities of $316,000 pursuant to FAS 121 in fiscal 1996.
 
YEAR 2000
 
     The Company recognizes the potential problem posed to its operations by its
dependence upon date sensitive computer systems and applications throughout its
business and the operations of third parties upon whom the Company is dependent.
The Company relies heavily on computerized laboratory equipment both for its
ongoing research and production scale-up projects as well as computer controlled
commercial scale manufacturing equipment in place in the Company's Scottish
facility. In addition, the Company, through strategic alliance and supply
agreements currently in place, is 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.
 
     The Company will utilize 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 the Company's Year 2000
compliance program began in the fourth quarter of fiscal 1998. Due to the
limited size of the Company's administrative staff, it is expected that most of
this work will be performed by outside contractors retained specifically for
this project. The Company expects to complete its internal Year 2000 project by
March 1999. The total estimated cost to the Company to complete its internal
Year 2000 project is $50,000 to $70,000, including projected hardware
replacements indicated. Funding for the evaluation and corrective phases will be
provided from general working capital.
 
     The Company has contacted certain external third parties, including raw
material vendors and scientific equipment manufacturers considered critical to
its current and planned future operations to discuss and evaluate their own
compliance programs.
 
     The costs and projected completion dates of the Company's Year 2000
compliance program is based on management's best estimates and is dependent in
large part upon compliance programs of external third parties or scientific
equipment and software vendors over whom the Company has no direct control.
Accordingly, the inability of the Company or critical vendors to meet Year 2000
compliance deadlines could have a material adverse impact on the Company's
operations from a product development, clinical trial or commercial
manufacturing standpoint, negatively affecting its financial condition, results
of operations and cash flows.

     year employment agreement under terms similar to his previous agreement
     except for certain notice of termination provisions. This agreement
     provided for a salary of $120,000 per year with an additional $5,000 per
     month, payable monthly, for the first six months of the contract term. In
     July 1998, Mr. Zeiger resigned for health reasons his position as Chief
     Executive Officer of the Company and Director of VEL, effective September
     30, 1998. Mr. Zeiger will continue to serve as Vice Chairman and as Senior

     Healey entered into an additional employment agreement with Viragen
     (Europe) Ltd. This agreement provided for a salary of $85,000 per year and

     the principal amount of $36,250 with the shares being issued into escrow
     pending cash payments further providing the shares may be released from
     escrow in increments of no less than $3,000. Mr. Healey received a bonus
     equal to the par value ($1,250) of the shares purchased. On June 6, 1996,
     the Company forgave Mr. Healey's note in lieu of bonus for the 1996 fiscal
     year, following unanimous approval of the independent members of the Board
     of Directors. On March 1, 1997 Mr. Healey entered into two-year employment

     respectively, and further provided for options to purchase 300,000 shares
     of common stock at $3.22 per share, exercisable over five years.

     employment agreement subsequently amended on July 3, 1997, to run
     concurrent with Mr. Smith's and superceding all previous agreements. This

     June 30, 1997, $52,000 for the year ended June 30, 1998 and $38,000 for the

     with Charles Fistel to serve as Executive Vice President, providing for an

     the Company issued to Mr. Fistel five-year options to purchase 250,000
     shares at $2.75 per share. The Company recognized $218,750 in compensation
     expenses as a result of the issuance of these options. On July 1, 1998,
     upon the expiration of Mr. Fistel's 1996 agreement, the Company entered
     into a two year employment agreement with Mr. Fistel under terms similar to
     his previous employment, modified to increase his salary to $172,500 during
     the two year term.
 
(5) From March 1996 to May 1996, Dr. Sawardeker served as an consultant to the
     Company in scientific affairs. On May 6, 1996, Dr. Sawardeker entered into
     two year employment agreement effective July 1, 1996, providing for a
     salary of $100,000 for the first and second years, respectively, and the
     issuance of a five year option to acquire 250,000 shares of Common Stock,
     exercisable at $1.80 per share, with one third of the options vesting on
     the effective date of the employment agreement and an additional one third
     vesting on the first and second anniversary dates, respectively. Dr.
     Sawardeker's employment agreement was subsequently amended and extended

     period from February 10, 1997 to February 9, 1998 and $160,000 for the
     period from February 10, 1998 to June 30, 1999. Dr. Sawardeker's amended

     200,000 shares of Common Stock, exercisable at $1.59 per share with all
     options vesting June 30, 1999.
 
     In November 1995, VSL, a wholly-owned subsidiary of VEL issued an aggregate
of 7.144 shares of VSL common stock at $56.00 per share to individuals serving
as officers and directors of VEL and one employee of the Company. Pursuant to
the Agreement and Plan of Reorganization, these shares were exchangeable into an

Healey, all serving as officers and directors of VEL, and one employee of the
Company. All options on VSL were exercised and the related shares exchanged for

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 subsequently amended, called the "1995 Stock
Option Plan." On September 22, 1995, the Board of Directors amended the 1995
Stock Option Plan (collectively the "95 Plan") to define certain terms and
clarify the minimum exercise price of the Non-Qualified Options, described
herein, as not less than 55% of the fair market value. The 95 Plan was submitted
to the stockholders of the Company 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" (the
"97 Plan"), containing terms and provisions similar to the 95 Plan. The 97 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 Plan reserving an additional 1,000,000
shares of Common Stock for issuance under the 1997 Plan, thereby reserving an
aggregate of 4,000,000 shares of Common Stock for issuance pursuant to options
granted under the 1997 Plan. On July 31, 1998, the stockholders rectified this
amendment to the 1997 Plan.
 
     Under both the 95 Plan and the 97 Plan (collectively the "Plans"), the
Company has reserved 8,000,000 shares (4,000,000 shares -- 95 Plan and 4,000,000
shares -- 97 Plan) of Common Stock for issuance pursuant to options granted
under the Plans ("Plan Options"). The Audit, Finance and Compensation Committee
of the Board of Directors (the "Committee") and the Board of Directors currently
administer the Plans including, without limitation, 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 the Plans may either be options qualifying as
incentive stock options ("Incentive Options") under Section 422 of the Internal
Revenue Code of 1986, as amended, or options that do not so qualify
("Non-Qualified Options"). In addition, the Plans also allow for the inclusion
of a reload option provision ("Reload Option"), 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, but
the exercise price of any Incentive Option granted to an eligible employee
owning more than 10% of the Company's 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 Committee, provided that 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 the Company's
Common Stock, no more than five years after the date of the grant.
 
                                       27
<PAGE>   29
 
     The exercise price of Non-Qualified Options shall be determined by the
Board of Directors or the 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 the Company's
capitalization, but any such adjustment shall not change the total purchase
price payable upon the exercise in full of Plan Options granted under the Plans.
 
     Officers, directors, key employees and consultants of the Company and its
subsidiaries are eligible to receive Non-Qualified Options under the Plans. Only
officers, directors and employees of the Company who are employed by the Company
or by any subsidiary thereof are eligible to receive Incentive Options.
 
     Incentives Options are nonassignable and nontransferable, except by will or
by the laws of descent and distribution, and during the lifetime of the
optionee, may be exercised only by such optionee. Under a recent amendment to
the 1997 Plan, Non-qualified Options may be transferable under limited
circumstances to facilitate 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 of the Company but is a member of the Company'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 shall 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 Committee may amend, suspend or terminate the
Plans at any time, except that no amendment shall be made which (i) changes the
minimum purchase price therefor (except in either case in the event of
adjustments due to changes in the Company's capitalization), (ii) affects
outstanding Plan Options or any exercise right thereunder, (iii) extends the
term of any Plan Option beyond ten years, or (iv) extends the termination date
of the Plans. Unless the Plans shall theretofore have been suspended or
terminated by the Board of Directors, the 95 Plan shall terminate on May 15,
2005 and the 97 Plan shall terminate on January 27, 2007. Any such termination
of either Plan shall not affect the validity of any Plan Options previously
granted thereunder.
 
     As of September 21, 1998, 3,991,500 options have been issued under the 1995
Amended Stock Option Plan and 2,987,000 options have been issued under the 1997
Stock Option Plan.

BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Section 16(a) of the Exchange Act requires the Company's directors and
executive officers, and persons who own more than ten percent (10%) of a
registered class of the Company's equity securities, to file with the Commission
initial reports of ownership and reports of changes in ownership of Common Stock
and other equity securities of the Company. Officers, directors and greater than
ten percent (10%) stockholders are required by Commission regulation to furnish
the Company with copies of all Section 16(a) forms they file.
 
     To the Company's knowledge, based solely on a review of the copies of such
reports furnished to the Company and written representations that no other
reports were required, during the fiscal year ended June 30, 1998, all Section
16(a) filing requirements applicable to its officers, directors and greater than
ten percent (10%) beneficial owners were completed and timely filed.
 
ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     On December 8, 1995, the Company consummated an Agreement and Plan of
Reorganization with Sector Associates, Ltd. (the former name for Viragen
(Europe), Ltd.) ("VEL") pursuant to which VEL acquired 100% of the outstanding
capital stock of Viragen (Scotland) Ltd. in exchange for which Viragen received
newly issued shares of convertible securities of VEL which represented
approximately 94% of the then issued and outstanding capital of VEL. Prior
thereto, on July 12, 1995, Viragen Technology, Inc., a wholly-owned subsidiary
of the Company, entered into a License Agreement with VSL pursuant to which
 
                                       30
<PAGE>   32
 
VSL obtained certain exclusive rights applicable to the EU countries and
none-exclusive rights throughout the world (except within the United States and
its territories) to engage in the manufacture and distribution of certain
proprietary products and technologies relating to the therapeutic application of
human leukocyte interferon. The term of the license is for 15 years, which is
automatically renewed for successive 15-year periods. At the present time, the
Company maintains at 70.3% capital stock interest in VEL, which in turn owns all
of the capital stock of VSL.
 
     Messrs. Gerald Smith, Robert H. Zeiger and Dennis W. Healey, who are
principal executive officers with the Company, also serve as the principal
executive officers of VEL. Messrs. Smith, Healey and Fistel also serve as
principal executive officers of the Company's 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 VEL's Executive Vice President,
Treasurer and Secretary, began receiving an annual salary of $85,000 per year
from VEL. On March 1, 1997, Messrs. Smith and Healey entered into two year
employment agreements, subsequently amended, with VEL until terms similar to
their employment agreements with the Company. The Agreements provide for annual
salaries of $72,000 and $52,000, respectively. In November 1995, VSL issued
options to purchase 100,000 share of each of its Common Stock to Messrs. Smith,
Zeiger and Healey, which following the consummation of the Sector reorganization
agreements, were converted into options to purchase and aggregate of 300,000
shares of Common Stock of VEL exercised at $.001 per share. All of such options
were exercised on January 31, 1996.
 
     On April 25, 1997, the Company 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 the Note. Due to a subsequent deterioration
in Mr. Saeger's health and financial condition, the Company was 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 at
year end. The Company intends to pursue collection efforts relative to this
transaction.
 
     On September 1, 1998, Messrs. Smith and Healey each exercised 250,000
options to purchase Common Stock of the Company. The options were exercised
through the issuance of Promissory Notes payable to the Company totaling
$300,000, and related Pledge and Escrow Agreements. The Promissory Notes bear
interest at the greater of (i) 3.5% or (ii) the Mid-Term Applicable Federal Rate
(as defined in Section 1274 of the Internal Revenue Code of 1986), payable
semi-annually and are secured by the underlying Common Stock purchased, which
shares are being held in escrow pending payment of the related Notes pursuant to
the provisions of the Pledge and Escrow Agreements.

               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, 1998 and 1997, and the related consolidated
statements of operations, stockholders' equity and cash flows for each of the
three years in the period ended June 30, 1998. 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, 1998 and 1997, and the consolidated
results of their operations and their cash flows for each of the three years in
the period ended June 30, 1998, in conformity with generally accepted accounting
principles.

                         VIRAGEN, INC. AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                             JUNE 30, 1998 AND 1997
 
NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Organization and Consolidation: 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 accounts of Viragen, Inc. and its wholly-owned subsidiaries, Vira-
Tech, Inc., Viragen Reagents, Inc. and Viragen Technology, Inc., and its
majority-owned subsidiaries Viragen U.S.A., Inc. ("VUSA") and Viragen (Europe)
Ltd. ("VEL"), including its wholly-owned subsidiaries, Viragen (Scotland) Ltd.
("VSL") and Viragen (Germany) GmbH ("VGG"), collectively known as the Company.
All material intercompany accounts and transactions have been eliminated in
consolidation.
 
     Cash and Cash Equivalents: The Company considers all highly liquid
investments with a maturity of three months or less when purchased to be cash
equivalents.
 
     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.
 
     FAS 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. The Company believes
no impairment indicators exist at June 30, 1998.
 
     Sale of Stock By Subsidiaries: The Company accounts for sales of stock by
its subsidiaries as capital transactions for financial reporting purposes.
 
     Loss Per Common Share: Loss per common share has been computed based on the
weighted average number of shares outstanding during each period. The effect of
warrants and stock options (common stock equivalents) are antidilutive. Diluted
loss per share data, which includes the assumed conversion of the convertible
preferred stock, has not been presented because it is not dilutive. Loss
attributable to common stock reflects adjustments for cumulative preferred
dividends, as well as, embedded dividends arising from discounted conversion
terms on the Company's Convertible Preferred Stocks and related Warrants.
 
     Effective during the quarter ended December 31, 1997, the Company adopted
FAS 128 -- Earnings per Common Share. All periods presented reflect the adoption
of FAS 128.
 
     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, 1998. 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.
 
     Marketable securities, available-for-sale: The Company has invested 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 Company's investment in
marketable securities, available-for-sale totaled $6,108,503 and $18,559,013 at
June 30, 1998 and 1997, respectively. Realized gains and losses are computed
based on the cost of securities sold using the specific identification method.
 
     Reclassification: Certain reclassifications have been made to June 30, 1997
and 1996 financial statement amounts to conform to the presentation for the June
30, 1998 financial statements.
 
     Estimates: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

                             JUNE 30, 1998 AND 1997
 
     Deferred Income: The Company has deferred the recognition of income from an
option fee until the period in which it is earned.
 
     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.
 
     Foreign Currency Translation: The financial statements of VSL have been
translated into U.S. dollars in accordance with Statement of Financial
Accounting Standards No. 52. All balance sheet accounts have been translated
using the current exchange rates at the balance sheet date. Income statement
amounts have been translated using the average exchange rate for the reporting
period. The translation adjustments resulting from the change in exchange rates
from year to year have been reported separately as a component of stockholders'
equity. Foreign currency transaction gains and losses, which are not material,
are included in results of operations. These gains and losses result from
exchange rate changes between the time transactions are recorded and settled
and, for unsettled transactions, exchange rate changes between the time
transactions are recorded and the balance sheet date.
 
     Stock Based Compensation: The Company 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.
The Company provided supplemental disclosures as required by the provisions of
FAS 123 -- Accounting for Stock-Based Compensation.
 
     Recent Pronouncements: In 1997, the Financial Accounting Standards Board
issued Statement of Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" (SFAS No. 130) which establishes standards for reporting
and displaying comprehensive income. SFAS No. 130 will be adopted by the Company
in the first quarter of fiscal 1999.
 
     In 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information" (SFAS No. 131), which is effective for years
beginning after December 15, 1997. SFAS No. 131 establishes standards for the
way that public business enterprises report information about operating segments
in annual financial statements and requires that those enterprises report
selected information about operating segments in interim financial reports. It
also establishes standards for related disclosures about products and services,
geographic areas, and major customers. SFAS No. 131 is effective for financial
statements for fiscal years beginning after December 15, 1997, and therefore the
Company will adopt the new requirements July 1, 1998.
 
     Management believes that the impact of SFAS No. 130 and SFAS No. 131 will
not be significant to the Company.
 
NOTE B -- REDEEMABLE PREFERRED STOCK
 
SERIES G CONVERTIBLE PREFERRED STOCK
 
     In September 1997, the Company concluded an Exchange Agreement whereby
4,000 of the outstanding shares of 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 667 preferred shares ($667,000) per month over a 6 month period. The
provisions further provided that the Company was required to redeem 667 shares
($667,000) per month less the number of Series G Preferred Stock shares
converted during the preceeding calendar month. In addition, the holder was
restricted from converting into common stock if the market price of the
Company's common stock was less than $2.50, subject to adjustment, at the date
of the conversion notice. In consideration for the restrictions on conversion,
the Company agreed to increase the dividend rate from 5% for the Series E
Preferred Stock to 10% for the Series G Preferred Stock.

                             JUNE 30, 1998 AND 1997
 
     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 I CONVERTIBLE PREFERRED STOCK
 
     During the third and fourth fiscal quarters of 1998, the Company closed $7
million of financing replacing a portion of the funds used to redeem previous
preferred stock issuances. In February 1998, the Company received net proceeds
of approximately $4,625,000 from the sale of 500 shares of its Series H
Convertible Preferred Stock (the "Series H Preferred Stock") with an aggregate
stated value of $5 million. In April 1998, the Company received net proceeds of
approximately $1,840,000 from the sale of 200 shares of its Series I Convertible
Preferred Stock (the "Series I Preferred Stock"). The Company incorporated
certain restrictions as part of the Series H and Series I Preferred Stock
designations which the Company believes will facilitate a more orderly market
relative to the underlying shares of its Common Stock. The Series H and Series I
Preferred Stock bear no dividends although, upon liquidation or conversion, an
8% accretion factor will be 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 (i) the fixed
conversion price, which was equal to the lower of the average closing price per
share for the 5 days prior to closing ($2.15 per share) or the market price of
the Common Stock six months following the closing date ($1.59 per share), and
(ii) the variable conversion price which will be equal to 82% of the market
price at the date of conversion. The Company 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 is 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 (i)
remain qualified for trading; (ii) convert preferred shares to common stock; and
(iii) maintain an effective registration statement. Upon the occurrence of an
event of default, the holders of the Series H Preferred Stock 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 the Company'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 Preferred Stock and Series I Preferred Stock also received Nine Month
Warrants, Twelve Month Warrants and Fifteen Month Warrants to purchase shares of
Common Stock of the Company.
 
     The Nine Month Warrants are exercisable from November 19, 1998 to February
19, 2003 and entitle the holders to purchase Common Stock at an exercise price
calculated by averaging the 2 lowest closing bid

prices during the 20 trading days of the Common Stock prior to November 19,
1998. The number of Shares the Nine Month Warrants may be converted into will be
calculated at 10% of the quotient obtained by dividing the stated amount of
preferred stock purchased by the exercising holder less any preferred stock of
that series transferred or converted by the holder by the Nine Month Market
Price.
 
     The Twelve Month Warrants and the Fifteen Month Warrants are identical in
all respects to the Nine Month Warrants with the exception of the calculation of
exercise prices, and the Twelve Months Warrants and the Fifteen Months Warrants
may not be exercisable prior to February 19, 1999 and May 19, 1999,
respectively. The Twelve Month Warrants entitle the holders to purchase Common
Stock at an exercise price calculated by averaging the 2 lowest closing bid
prices during the 20 trading days of the Common Stock prior to February 19,
1999. The number of shares the Twelve Month Warrants may be converted into will
be calculated at 15% of the quotient obtained by dividing the stated amount of
preferred stock purchase by the exercising holder less any preferred stock of
that series transferred or converted by the Holder by the Twelve Month Market
Price. The Fifteen Month Warrants entitle the holders to purchase Common Stock
at an exercise price calculated by averaging the 2 lowest closing bid prices
during the twenty (20) trading days of the Common Stock prior to May 19, 1999.
The number of shares the Fifteen Month Warrants may be converted into will be
calculated as 20% of the quotient obtained by dividing the principal amount of
preferred stock purchased by the exercising holder less any preferred stock of
that series transferred or converted by the holder by the Fifteen Month Market
Price.
 
     Pursuant to the Series H and Series I Placement Agent Agreements between
the Company and the Placement Agent, the 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 the Placement Agent Warrants to purchase an aggregate of 402,052 shares
of Common Stock of the Company, which were subsequently transferred to
affiliates and employees of the Placement Agent. The Placement Agent Warrants
entitle the holders thereof to exercise the Placement Agent Warrants at an
exercise price of $1.684 per share ("Initial Exercise Price") 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 of the Initial Exercise Price
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
 
     The Series A Preferred Stock provides for a 10% cumulative dividend,
payable at the option of the Company, 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. The Company 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
("Redemption Trigger Date"). The preferred stock is redeemable at $11.00 per
share for a period of five years from the Redemption Trigger Date, and
thereafter at $10.00 per share.
 
     In fiscal 1996, 800 shares of Series A Preferred Stock, including dividends
in arrears, were converted into 6,500 shares of Common Stock.
 
     On June 7, 1996, the Company entered into a Securities Purchase Agreement
(the "Agreement") with GFL Performance Ltd., GFL Advantage Fund Ltd. and Proton
Global Asset Management, LDC (collectively the "Purchaser") pursuant to which
the Purchaser acquired 15,000 shares of the Company's 5% Cumulative Convertible
Preferred Stock, Series B (the "Series B Preferred Stock") for $15 million.

                             JUNE 30, 1998 AND 1997
 
     In connection with the sale and issuance of the Series B Preferred Stock,
the Company issued warrants to purchase 225,000 shares of Common Stock of the
Company at $10.59 per share for a period of 3 years from date of issuance along
with 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.
 
     The Series B Preferred Stock provided for a cash dividend equal to 5% of
the stated value of the Series B Preferred Stock, payable quarterly commencing
September 7, 1996, although the Company had the option to utilize shares of its
Common Stock, under certain conditions, to satisfy the dividend requirement. The
Purchaser had the right to convert the Series B Preferred Stock commencing
August 21, 1996 into shares of Common Stock of the Company at a conversion price
equal to the lesser of 85% of the average market price (reduced by an additional
2% per month commencing the 90th day following the closing date, until the
related Registration Statement was declared effective by the SEC) for the
Company's Common Stock, as described in the Agreement, prior to the conversion
date or $8.74. The final conversion rate was set at 76.8% of the average market
price. 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 of the Company. The principal value of the
Note was comprised of the following components: 1) face value of Series B
preferred stock outstanding at July 1, 1997; 2) preferred dividends earned
through the date of the Note; and 3) an amount reflecting the preferential
conversion terms. The Note was paid-in-full in April 1998.
 
     In December 1996, the Company issued 5,000 shares of its Series C
Convertible Preferred Stock (the "Series C 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. (collectively the "Series C Purchasers"),
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 Series C
Purchasers.
 
     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 of the Company on
or after 10 days from the date the registration statement registering the
underlying shares is 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 Preferred Stock ($1,000
per share) by the closing price of the Company's Common Stock over the five day
period preceding notice of conversion ("conversion price"). 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
($1,000 face value per share) over a two month period. The modified conversion
price was the lower of (i) $2.20 per share or (ii) the average closing price of
the Company'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, the Company was 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, the
Company 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.
 
     In February 1997, the Company issued 15,000 shares of its 6% Series D
Convertible Preferred Stock (the "Series D 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 Stock was convertible into a number of shares of Common Stock
of the Company determined by dividing the five day trading average price of the
Company's 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, the Company also issued 375,000 Common Stock
Purchase warrants, exercisable at $6.00 per share.
 
     In September 1997, the Company 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 limitation on the holder limiting
conversion during any two week period to 800 preferred shares ($800,000). The
terms also provided the Company 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, the Company 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, the Company paid $2,744,000 to the Series F holder upon exercise of
the cash-out option on conversions.
 
     In February 1997, the Company also issued 5,000 shares of its 5% Series E
Convertible Preferred Stock (the "Series E Preferred Stock") in consideration
for $4,681,744 (net of issuance costs totaling $318,256). Dividends on the
Series E Preferred accrued from the date of issuance and were payable quarterly
commencing April 1, 1997 and were payable in cash or, at the Company's option
and subject to certain other conditions, in shares of Common Stock of the
Company.
 
     The Series E Preferred Stock was convertible into shares of Common Stock of
the Company commencing May 11, 1997 at a conversion price of the lesser of (i)
the Average Market Price for the five trading days prior to the Notice of
Conversion multiplied by 85%, subject to adjustment, or (ii) $7.00, subject to
adjustment.

OPTIONS AND WARRANTS
 
     On May 15, 1995, as amended in September 1995, the Company adopted its 1995
Stock Option plan under which 4,000,000 shares of Common Stock were reserved for
issuance to officers, directors, employees and consultants of the Company for
stock options designated as "incentive stock options" within the meaning of
Section 422 of the Internal Revenue Code. Options granted under the plan have
various vest dates and all options granted have five-year terms from the vesting
date.
 
     In September 1995, the Board of Directors granted 2,935,000 non-statutory
options to directors, officers and key employees of the Company under the
provisions of the 1995 Stock Option Plan. The options granted have an exercise
price of a $.50 per share and are exercisable for a period of five years. The
Company recognized compensation expense of $183,144 in fiscal 1996 as a result
of these grants.
 
     During September 1995, 75,000 warrants issued to a financial consultant
having an exercise price of $.30 per share and 6,250 warrants issued in
connection with the Company's August 1994 Private Placement offering with an
exercise price of $.52 per share were exercised into common stock of the
Company. In December 1995, a Director of the Company exercised 50,000 options
with an exercise price of $.30 per share.
 
     In March 1996, the Company issued 636,000 Common Stock Purchase Warrants,
300,000 of which were associated with the Company's Florida HIV Study with the
balance issued for financial consulting services. The Company recognized expense
during fiscal 1996 resulting from this issuance of $316,300.
 
     During the third quarter of fiscal 1996, officers and directors exercised
1,000,000 options granted in June 1994, at $.30 per share through the issuance
of promissory notes totaling $290,000 secured by the related stock which was
held in escrow pending payment of the related promissory notes. The notes and
related interest due were forgiven by the Company during the fourth quarter of
fiscal 1996.
 
     In June 1996, a new Director was elected into the Board of Directors. The
Director was granted 25,000 common stock options upon election to the Board. The
options are exercisable at $3.96 per share for a period of five years.
 
     The Company's 1997 Incentive Stock Option Plan (the "1997 Plan"), adopted
February 1997, authorized the grant of options to management personnel,
directors and employees for up to 3,000,000 shares of the Company's common
stock. In April 1998, the 1997 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.
 
     During fiscal 1997, the Company granted a total of 2,941,500 options to
purchase common stock of the Company. Of these, 1,750,000 were granted to the
directors of the Company. 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, the Company 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.
 
     The Company 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 year 1997, the Company issued 120,000 options that were not
part of the above Plans to an employee. The options vested immediately and have
a 5 year term from that date.
 
     For the year ended 1997 the Company recognized $3,710 in compensation
expense on warrants granted to consultants.

     During fiscal 1998, the Company 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.
 
     The Company 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. The Company recognized $57,530 in compensation
expense on warrants issued to consultants.
 
     At June 30, 1998, 8,500 shares and 1,013,000 shares remain available under
the 1995 Stock Option Plan and the 1997 Stock Option Plan, respectively.
 
STOCK BASED COMPENSATION
 
     The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" ("APB 25") and related
Interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FASB
Statement No. 123, "Accounting for Stock-Based Compensation," ("Statement 123")
requires use of option valuation models that were not developed for use in
valuing employee stock options. Under APB 25, the Company recognized
compensation expense in the amount of $-0-, $381,500 and $499,444 in 1998, 1997
and 1996, respectively, because the exercise price of a portion of the Company's
employee stock options and warrants was less than the market price of the
underlying stock on the date of grant. During 1998, the Company recognized
$57,530 in compensation expense on options and warrants granted to consultants
pursuant to FAS 123.
 
     Pro forma information regarding net income and earnings per share is
required by Statement 123, and has been determined as if the Company had
accounted for its employee stock options and warrants under the fair value
method of that Statement. The fair value for these options and warrants 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 the Company's common stock of .75, .64 and .60 for 1998, 1997 and 1996,
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 the Company's employee stock options and warrants 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.
 
     For purposes of pro forma disclosures, the estimated fair value of the
options and warrants is amortized to expense over the option's or warrant's
vesting period. The effect of applying Statement 123 for providing pro forma
disclosure are not indicative of future amounts until the new rules are applied
to all nonvested awards. The Company's pro forma information follows:

NOTE E -- CORPORATE REORGANIZATION
 
     On September 20, 1995, the Company entered into an agreement and Plan of
Reorganization ("Agreement") with Sector Associates, Ltd. ("Sector"), a Delaware
corporation. Under the terms of the Agreement, the Company acquired a 94%
interest in Sector, a publicly-traded corporation, in consideration for a 100%
interest in VSL. VSL was organized during April 1995, by Viragen, Inc. to
manufacture and distribute Viragen's natural leukocyte-derived alpha interferon
and related products in the EU and other countries outside the United States.
Viragen retained an 84% ownership interest in Sector, as shares in Sector were
disbursed to the new Directors and to an affiliate. Shares were also disbursed
as finders' fees.
 
     On November 7, 1995, the Agreement was amended to provide for an interim
loan of $500,000 by Sector to VSL, the filing of certain financial reports by
Sector prior to closing, an additional capital contribution of $300,000 into
Sector within thirty days, and the modification of a related investment banking
agreement. The $500,000 loan was funded November 9, 1995, bearing interest at 4%
per annum, secured by a 3.77% equity interest in VSL, and was guaranteed by
Viragen, Inc. Upon the closing of the Agreement on December 8, 1995, the
principal amount of the note was deemed contributed capital to Sector.
 
     The Agreement was finalized and became effective on December 8, 1995.
 
     In March 1996, Sector completed two Private Placement Offerings, issuing
768,000 shares of Common Stock and 216,500 Common Stock Purchase Warrants having
an exercise price of $12.00 per share. These two Offerings yielded net proceeds
of approximately $5,102,000 after related cash expenses of $371,500. The Company
is using these proceeds to undertake European research and pre-clinical trials
activities including the construction of its laboratory and manufacturing
facility in Scotland.
 
     Effective May 2, 1996, Sector's name was changed to Viragen (Europe) Ltd.
 
NOTE F -- INCOME TAXES
 
     Viragen, Inc. and its majority-owned subsidiaries, as defined by the

                             JUNE 30, 1998 AND 1997
 
     In November 1996, the Company forgave a $12,500 balance due to the Company
by its Chief Executive Officer.
 
     In April 1997, the Company loaned $100,000 to a director of the Company.
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 (the
Prime Interest Rate in effect at that time). In April 1998, the director
defaulted on the Note. The Company 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 has been written-off as uncollectable at year end. The Company intends
to pursue collection efforts relative to this transaction.
 
     On July 31, 1998, the Company held its 1997 Annual Shareholders Meeting.
Certain directors did not seek reelection to serve as Directors of the Company.
In appreciation of their past service, the Company 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.
 
     Subsequent to June 30, 1998, certain officers and directors of the Company
exercised 750,000 stock options to purchase Common Stock of the Company. The
options were exercised through the issuance of Promissory Notes payable to the
Company with related Pledge and Escrow Agreements. The Promissory Notes bear
interest at the greater of (i) 3.5% or (ii) the Mid-Term Applicable Federal Rate
(as defined in Section 1274 of the Internal Revenue Code of 1986), payable
semi-annually and are secured by the underlying Common Stock purchased, which
shares are being held in escrow pending payment of the related notes pursuant to
the provisions of the Pledge and Escrow Agreements.
 
NOTE H -- IMPAIRMENT OF LONG-LIVED ASSETS
 
     During fiscal 1997, the Company entered into negotiations with Medicore,
Inc. ("Medicore"), a former affiliate, for the sale of its land, building and
related improvements located in Hialeah, Florida. Preliminary negotiations
established the fair value of the land, building and improvements to be
$400,000. At June 30, 1996, the land, building and improvements had a net
carrying value of $716,267. In accordance with FAS 121, the Company recorded an
impairment loss of $316,267, which was included as part of selling, general and
administrative expenses for the year ended June 30, 1996.
 
     The Company and Medicore terminated discussions relating to the sale of the
Company's Hialeah, Florida facilities during fiscal 1997. The Company intends to
maintain this location as a research facility for the foreseeable future.
 
NOTE I -- LICENSE AND MANUFACTURING AGREEMENTS
 
     Through a fifteen-year License Agreement (the "License") granted by
Viragen, Inc., VEL and its wholly-owned subsidiary, VSL, 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 (the "Product") for various diseases that affect
the human immune system. Pursuant to these rights, on July 20, 1995, VSL entered
into a License and Manufacturing Agreement ("Scottish Agreement") with the
Common Services Agency ("Agency"), an agency acting on behalf of the Scottish
National Blood Transfusion Service ("SNBTS") pursuant to which SNBTS, on behalf
of VSL, will manufacture and supply VSL's Product to VSL for distribution in the
European Union in return for certain fees. It was considered critical to VSL's
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. VSL commenced operations concurrent with the execution of its agreement
with SNBTS. The term of the Scottish Agreement is five years with two additional
five-year extension terms exercisable at the option of VSL.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                             JUNE 30, 1998 AND 1997
 
     Pursuant to the terms of the License, VSL was to prepay $2 million to VTI,
within six months of the Effective Date (July 12, 1995). Commencing one year
from the Effective Date, VSL is to pay to VTI 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 VTI transferred the processes and technology, as defined by the
License, to VSL. VTI had substantially transferred the processes and technology
to VSL by the end of May 1997. At that time, VTI required the initial royalty
payment be made. Completion of the transfer occurred on November 1, 1997.
 
     The Company, through VTI, has executed an option for Southern Health
SDN.BHD ("Southern"), a private Malaysian/Australian-based healthcare investment
group to purchase a Manufacturing and Distribution License Agreement for
Viragen's natural alpha interferon product. Upon exercise of the option, the
Company is to receive a license fee of $20 million, payable in advance, and a
continuing royalty of 12% of gross revenues from the sale of the licensed
product. Southern has paid the Company a $200,000 option fee, $100,000 of which
is non-refundable and intended to deter the costs related to due diligence, with
the remaining $100,000 refundable, if the Company elects not to proceed with
this transaction. The Company has deferred recognition of revenue related to the
fee.
 
     Within the first two years of the Manufacturing and Distribution License
Agreement, Southern would be required to commence construction of at least one
regulatory approved manufacturing facility within the defined territory, which
includes Australia, New Zealand and seven other Asian countries exclusive of
China and Japan. The manufacturing facility would be built and operated in
compliance with Viragen's specifications. In addition, Southern will be
responsible for funding and conducting any clinical trials necessary within the
defined territory.
 
     Pursuant to an extension granted by the Company, Southern has until
December 31, 1998, to exercise the option. The Company believes that this
transaction may be negatively affected by instability in Asian financial
markets. Accordingly, there can be no assurance that this transaction will
ultimately be successfully concluded.
 
NOTE J -- RESEARCH AND DEVELOPMENT AGREEMENTS
 
     The Company has a contract with Viragen Research Associated Limited
Partnership, ("Limited Partnership") for the Company to perform the research and
development with respect to two therapeutic products for the topical treatment
of herpes virus infections. Pursuant to the contract, the Company assigned all
of its patent rights to the processes and topical products to the Limited
Partnership in exchange for an exclusive worldwide licensing agreement. The
Limited Partnership 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. The Company is not presently pursuing
the development or commercialization of a topically applied product.
 
NOTE K -- ROYALTY AGREEMENT
 
     The Company has a royalty agreement with Medicore 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.
Royalties expense incurred totaled $11,901 in 1996.

NOTE M -- CONTINGENCIES
 
     In May 1997, the Company in the name of Sector Associates, Ltd. (now VEL)
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 the Company'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 has been accrued at June
30, 1998.
 
     In October 1997, the Company, 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
(Case No: 97-3187-CIV-MARCUS) by a shareholder of the Company and investor in
Cytoferon Corp. The suit alleges 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. The Company 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 the Company of
their 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 the Company'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, the Company filed a Motion to
Dismiss the Plaintiff's Amended Complaint which was denied by the Court. The
Company denies the

regard to this matter. The ultimate liability, if any, cannot be determined at
this time and no accrual for loss has been recorded.
 
NOTE N -- GEOGRAPHIC INFORMATION
 
     In 1997, the Company completed a manufacturing facility in Edinburgh,
Scotland. Identifiable assets in Scotland totaled $4,745,000 and $7,178,000 at
June 30, 1998 and 1997, respectively. Identifiable assets represent those assets
used in the operations of the geographic area.
 
NOTE O -- SUBSEQUENT EVENTS
 
     In furtherance of the Company's strategic plan to secure reliable and safe
sources of human white blood cells ("leukocytes" or "buffy coats") critical to
the production of both Omniferon and LeukoVAX, the Company has entered into a
series of strategic alliance and supply agreements with major worldwide
suppliers of blood products. During 1998, Viragen consummated agreements with
the American Red Cross and America's Blood Centers, which between them annually
collect a substantial majority of the U.S. blood supply, and a series of
agreements covering a majority of the blood supply in Germany, with a major
European supplier.
 
     In July 1998, the Company and VUSA entered into a strategic alliance and
supply agreement with America's Blood Centers ("ABC") for the supply of human
white blood cells (leukocytes). ABC is a national network of non-profit,
independent community blood centers operating in 45 states. ABC members annually
collect in excess of 45% of the U.S. blood supply through its member blood
donation centers and mobile collection facilities. Under the terms of the ABC
Agreement, the Company was granted first and preferential access to all
leukocytes produced by ABC members who have elected to participate in the
program. The Company has agreed to pay a fixed cost per buffy coat provided
during the first two years of the ABC Agreement. Thereafter, the price may vary
based upon incremental costs incurred by participating ABC members.
 
     In August 1998, the Company and VUSA entered into a fifteen year Agreement
with the American Red Cross ("ARC") for the supply of human white blood cells.
ARC collects approximately half of the U.S. blood supply. The ARC Agreement
provides for the Company's purchase of buffy coats, consistent with agreed upon
specifications, based on quarterly forecasts provided by the Company. Buffy
coats may be paid for in cash or Common Stock of the Company at the option of
ARC, with the valuation of shares paid determined by the average closing price
of the Company's shares for the five days prior to the payment due date less a
discount. The ARC Agreement further contains an initial price per buffy coat
modified by a volume discount pricing schedule and rebate program, subject to
periodic renegotiation. Upon execution of the Agreement, ARC received a Warrant
to purchase 500,000 shares of Common Stock of the Company and 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 buffy
coat purchases. The Warrant vests over a six year period with exercise prices
ranging between $5.50 per share and $11.00 per share.
 
     In August 1998, the Company 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 has focused
on the development of therapeutic drugs for autoimmune disorders. Its lead
product is LeukoVAX, an immunomodulating therapy derived from leukocytes
currently in FDA Phase I/II clinical trials for rheumatoid arthritis.
 
     Under the terms of the Inflammatics Agreement, the Company made an initial
investment by purchasing Series A Convertible Preferred Stock of Inflammatics
for $1 million and warrants to purchase 200,000 shares of Common Stock of the
Company exercisable at $1.00 dollar per share, representing an initial 10%
equity interest in Inflammatics. The Company further obtained two options to
acquire up to an additional 70% equity

position in Inflammatics through two additional fundings to be made at the sole
option of the Company. Additional funding, if any, will be made based upon the
Company's evaluation of LeukoVAX clinical trial data and would be utilized to
underwrite a FDA Phase III clinical trial. As part of these options, the Company
may issue up to 3 million shares of its Common Stock and 300,000 additional
warrants to purchase Common Stock of the Company in exchange for additional
Series A Convertible shares of Inflammatics bringing the Company's total equity
position in Inflammatics to 80%.
 
     On September 22, 1998 the Company entered into an Equity Line Financing
Agreement ("Equity Line Agreement") for a maximum offering amount of $20 million
over three years. Provisions of the Equity Line Agreement provide that the
Company, at its option, may "Put" shares of Common Stock to the investor,
following an effective Registration Statement, at a "Put Share Price" equal to
the lesser of (a) 87.5% of the Market Price for such Put or (b) the difference
of (i) the Market Price of such Put minus (ii) $0.225 where the Market Price is
defined as the lowest Closing Bid Price during the 10 to 20 trading days
(depending upon the size of the Put) following each Put.
 
     The amount of Common Stock that may be Put in any 30 day period, is limited
to one half (1/2) of the aggregate daily reported trading volume in the
outstanding Common Stock reported during the 10 trading days preceding the Put
date. In addition, on each six month anniversary of the Subscription Agreement
date, the Company shall issue to the Subscriber a Purchase Warrant to purchase a
number of shares of Common Stock equal to 10% of the number of Put Shares issued
to the Subscriber during the preceding 6 calendar months. Each Purchase Warrant
shall be exercisable at 108% of the lowest closing bid price for the 10 trading
days immediately preceding each six month anniversary.
 
     In connection with the Equity Line Agreement, the Company also entered into
a Placement Agent Agreement which provides for a Cash Placement Fee on the gross
proceeds from the sale of the securities in any Put of: 7% on the first $5
million; 6% from $5 million to $10 million; and 3.5% for amounts in excess of
$10 million. If the Company were to Put securities for the entire $20 million
available under the Equity Line Agreement, the Cash Placement Fee would total 5%
of the total gross proceeds derived. In addition, the Placement Agent Agreement
provides for the issuance of Placement Agent Warrants to the Placement Agent
equal to: (i) 7%, 6% and 3.5%, respectively, on all shares issued in connection
with Put Shares at the same thresholds as the Cash Placement Fee, exercisable at
125% of the average Put Share Price of all Put Shares issued during the
preceding six calendar months; and (ii) a warrant to purchase a number of Common
Shares in the same percentages as above for which the subscriber has been issued
a Purchase Warrant, exercisable at 108% of the lowest closing bid price for the
10 trading days immediately preceding the applicable six month anniversary.
 
     As of the closing of the Equity Line Agreement, the Company had
approximately 1,900,000 shares of Common Stock available from authorized shares.
Accordingly, to utilize the total funding available under the Equity Line
Agreement, the Company must obtain Stockholder approval to increase the number
of authorized shares in the Company. In addition, to comply with NASDAQ National
Market regulations regarding potential dilution limitations, the Company intends
to seek Shareholder's approval of the Equity Line Financing Agreement.

                                       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.

                      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
                  similar debt settlement procedure or a bankruptcy position is
                  denied based on insufficient assets; or

         -        a party to the Agreement fails to discharge a material duty
                  (particularly duties to deliver and pay) under the Agreement
                  within thirty (30) days of a written demand to do so.

In the event of a termination without notice, the obligations pursuant to this
Agreement shall be fulfilled until the other party acknowledges the existence of
cause of until a final, non-appealable judgment has been rendered. In any case,
such performance may cease once the quantities ordered pursuant to SS.2(2) and
(3) have been delivered.

(3)      In the event of a premature termination pursuant to sub-section 2, the
         Contracting Party responsible for giving rise to the cause therefore
         shall be liable to the other Contracting Parties for any damages
         resulting from the premature termination. Liability based on any claim
         for lost profits shall be limited to DEM 1 million.

(4)      Notice of termination must be made in writing.

                              SURRENDING DOCUMENTS

 Upon the expiration or termination of the contract, each Contracting Party
 shall surrender any and all property relating to or owned by the other
 Contracting Party including, inter alia, books, writings and records. No
 Contracting Party has the right to withhold such property.

                                      SS.10
                                 NON-DISCLOSURE

 Each Contracting Party covenants not to disclose any matters, relationships and
 business secrets to which they have become privy by virtue of the contract.
 This covenant will continue to bind the Parties even after the contract has
 ended. A breach of this duty of non-disclosure and any other such duty under
 the other agreements between the Contracting Parties shall be deemed cause
 within the meaning of SS.8(2).

                                      SS.11
                                   PUBLICATION

 DRK-BSD is aware that under US law, Viragen is obligated to publish material
 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
 Parties. Viragen's compliance with its obligation under sentence one of this
 sub-section may not be thereby impaired. Consent will be deemed to have been
 given if no objection is lodged within one week following receipt of the
 publication draft.

                                      SS.12
                          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
         cost of living index for a 4-person household of civil servants and
         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


<PAGE>   8



         disappear (e.g., as a result of the Euro), then the index which
         replaces it or the one which is most similar to it will be deemed as
         the controlling index for purposes of this provision.

                                      SS.13

                                 Exhibit (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

"Affiliate" means any Person in which Viragen or its successor has, directly or
indirectly, an ownership interest of 20 percent or more. A "Non-Affiliate
Person" shall mean a Person which is not an Affiliate.

"Available Supply" shall mean during any forecast period either the greater of
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.

"Buffycoat Facility(ies)" shall mean any PIBCs' blood collection, processing,
fractionation, laboratory and testing facilities, as may be designated or
required to produce and deliver Buffycoats to VUSA's Sites.

                                   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.



                                       7

<PAGE>   9

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

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.

Agreement's termination, each party shall return to the other party all
Confidential Information acquired by it from such other party and all copies

15.7 Non-Assignment. Neither this Agreement nor any of the rights, interest or
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
or more of such party's affiliates, (b) any party may cause any affiliate to
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
substantially all of the assets of that party. No assignment shall relieve any
party of responsibility for any obligation hereunder.

15.8 Third-Party Beneficiaries. This Agreement and all of the provisions hereof
and of its Subagreement shall be binding upon and inure solely to the benefit
of each party hereto (including the PIBCs of each Subagreement), and any
successors in interest. Nothing in this Agreement and the Subagreements,
express or implied, is intended to or shall confer upon any other person (i.e.,
other than the parties and the PIBCs) any rights, benefits or remedies of any
nature whatsoever under or by reason of this Agreement.

15.9 Independent Contractor. Each of the parties, and each PIBC, is performing
its duties hereunder and under the Subagreements as an independent contractor,

Subagreements shall be governed by, and construed in accordance with, the laws
of the District of Columbia, except that matters related to corporate

interests shall be construed in accordance with the laws of the State of
Delaware, regardless of the laws that might otherwise govern under applicable
conflict of laws principles. The parties agree to use good faith best efforts
to resolve disputes prior to the filing of any action or claim. Any action or
claim shall be subject to binding arbitration conducted in the Washington, DC,
before the American Arbitration Association in accordance with its arbitration
rules or as modified by written agreement of the parties. Each party
acknowledges and agrees that any breach or threatened breach by any party of
the provisions of this Agreement, or the Subagreements, would cause immediate
and irreparable harm to the other party(ies), and that the resulting damages
and injuries to such other party would be irremediable in terms of monetary
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)
shall be entitled to resort to judicial proceedings in aid of arbitration if
interim injunctive relief from a court is necessary to prevent such irreparable
harm. In the event that any action or claim is brought, the substantially
prevailing party shall be entitled to recover its reasonable attorneys' fees.

Subagreement shall be deemed invalid or unenforceable, the remaining terms

efforts to substitute a valid, legal and enforceable provision, which insofar
as practical implements the purposes hereof.

party affected shall be reasonably excused from performance hereunder to the
extent and for the duration of such prevention, restriction or interference;
provided, however, nothing herein shall excuse any party from payment for sums
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
waiver in one instance or for one purpose shall not create an implied
obligation to give a waiver in another instance or for another purpose, with
respect to the same or a different event.

15.15 Enforcement of PIBC Obligations. ABC shall have the primary
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
obligations under this Agreement or the PIBC's Subagreement and not ABC's
breach of its obligations and that any termination of a Subagreement shall be
made by VUSA.

         Purchase Order accepted by ARC and produced and delivered by ARC that
         conform with the Specifications and delivered and accepted in
         accordance with Section 2.

     1.2 PAYMENTS. VUSA shall be obligated to pay ARC for Buffycoats ordered and
accepted by VUSA that conform with the Specifications in accordance with payment
requirements and volume discount price schedule and rebate program set forth
herein and in Exhibit 2.

                  (a) FORM OF PAYMENTS. ARC may, at its option, request in
         writing 15 days prior to any invoice due date, payment for Buffycoats
         supplied to VUSA in shares of the Company's common stock instead of
         cash. If ARC elects to receive payment in shares of Company's common
         stock, the formula for the determination of the number of shares of the
         Company's common stock to be issued shall be calculated by dividing the
         amount of monies due ARC by the product of (i) 100% minus the discount
         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
         to shares received in lieu of cash payments hereunder, as defined in
         the Registration Rights Agreement attached hereto as Exhibit 4b and
         made a part hereof.

                  (b) RIGHT TO PURCHASE. The Company or any of its Affiliates or
         designees shall have the first right to purchase any or all shares of
         common stock of the Company then owned by ARC, or ARC's Affiliates, at
         fair market value, in the event

         of any early termination or non-renewal of this Agreement.
         Notwithstanding the foregoing, no certificates for shares of common
         stock issued to ARC shall contain a legend or other reference to this
         Right of Purchase, and nothing shall prohibit ARC from selling or
         otherwise disposing of shares of common stock pursuant to the Warrants
         Agreement and Registration Rights Agreement prior to the receipt of any
         notice of the Right of Purchase hereunder.

the Company with respect to the shares underlying the Warrant and shares that
may be received by ARC in lieu of cash from Buffycoat purchases made by VUSA.
Such registration rights are specified in the Registration Rights Agreement
attached as Exhibit 4b and made a part hereof.

     1.4 RECALL OF BUFFYCOATS. In the event of a recall of Buffycoats initiated

(including any amount paid in the form of Company Stock), and reimburse VUSA for
all reasonable costs directly incurred in connection with the recall of the
Buffycoats and products made from Buffycoats that are subject to such recall.

     2.1 SHIPMENT AND ACCEPTANCE OF BUFFYCOATS. Buffycoats shall be shipped at

         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
         Buffycoat material was drawn from a blood donor. Any Buffycoats not
         accepted or that are rejected, or for which the acceptance is revoked,
         by VUSA shall be destroyed by VUSA in accordance with all applicable
         laws and ARC requirements and Standard Operating Procedures or, if so
         requested by ARC, returned to ARC at ARC's expense and instruction. ARC
         shall ensure that VUSA is immediately notified of any information
         regarding a shipment of Buffycoats that would reasonably suggest that
         it does not conform with Specifications or otherwise should not be used
         for the manufacture of parenteral use drug products (including any
         adverse observations by

         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
         promptly refunded or credited to VUSA's account as designated by VUSA.

                  (c) ARC shall permit and cooperate with representatives of
         VUSA, the FDA and other foreign and domestic regulatory authorities, to
         audit or inspect its facilities, equipment and documents, and interview
         its personnel as may be needed to assure ARC's compliance with this
         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
VUSA as soon as feasible of any event that has a material affect on ARC's
ability to deliver Buffycoats in full accordance with the Buffycoat Purchase

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.

     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

         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,

         Period for which such negotiations apply shall not serve to negate,

         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

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

breach of that term or of any breach of any other term of this Agreement,

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

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

unreasonably withheld.

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.

resolved as follows. The matter will first be submitted to the Board of
Directors of IFM which must approve unanimously any resolution of the matter if
VRGN does not hold a majority of the seats on the Board of Directors of IFM at
the time such matter is submitted to the Board of Directors of IFM. In any
event, the Board of Directors of IFM shall have 30 days to resolve such matter;
if the Board of Directors of IFM does not resolve the matter within such 30 day
period, the matter will be submitted to the respective Presidents of IFM and
VRGN, who shall meet (in person or by telephone) and attempt in good faith to
resolve the matter within 30 days after the matter has been submitted to each of

FDA relating to the Clinical Candidate or any Product, and (ii) within five (5)
business days after their receipt by the CRMC (or sooner if requested by the
FDA), all correspondence and other communications to the FDA shall be reviewed
and approved in advance by the CRMC in accordance with Section 2.2. The CRMC (or
the IRBs, if appropriate) shall be notified promptly upon receipt of any
correspondence and other communications from the FDA, and copies thereof shall
be promptly given to the CRMC (or the IRBs, if appropriate); and VRGN shall have

or trial and submitted in a form that meets FDA's requirements relating to the
preparation and submission of INDs and NDAs in a timely manner to the CRMC and
VRGN in accordance with Sections 3.1.1 and 3.1.2.

     2.5 Time is expressly made of the essence with respect to each Party's
performance under the Clinical Research Plan.

     2.6 USE OF THIRD PARTIES BY IFM. During the term of this Agreement, IFM
may, in accordance with the Budget and Schedule, utilize the services of outside
consultants or other Third Parties in connection with performing its work and
conducting studies and clinical trials under this Agreement (which shall be at
IFM's sole expense as provided for in the Budget, unless otherwise provided for
herein); provided, 

                                       9
<PAGE>   10
however, that IFM assumes full responsibility and liability for such Third
Parties. Accordingly, IFM shall defend, indemnify and hold harmless VRGN and its
Affiliates and their respective directors, officers, agents and employees,
successors and assigns from and against any and all liabilities, claims,
actions, suits, damages, losses, costs and expenses, fines and penalties
(including without limitation attorney's fees and other costs of litigation,
regardless of outcome) arising out of or related to the services of Third
Parties in connection with performing any work or conducting any studies or
clinical trials under this Agreement. VRGN shall have the right to approve in
advance in writing any Third Party utilized by IFM to perform work or conduct
studies or clinical trials on behalf of IFM under this Agreement, which approval
shall not be unreasonably withheld or delayed, but no such approval by VRGN will
affect IFM's responsibility and liability for such Third Party, nor shall it
limit IFM's indemnification obligations under this Section 2.6.

                         2.7 REPORTS; SHARING OF DATA.

     2.7.1 IFM shall make available and disclose to VRGN, as soon as such
information, data, results and analyses become available to IFM, all data
(including raw data), information and results generated pursuant to studies
and/or clinical trials conducted under the Clinical Research Plan (including all
analyses thereof). IFM shall make available and disclose to the CRMC, on no less
than a quarterly basis, summaries of the progress of such studies and/or
clinical trials and other activities for which IFM is responsible under the
Clinical Research Plan.

     2.7.2 All data (including raw data), information, results and analyses
generated by or on behalf of IFM pursuant to the Clinical Research Plan,
including all Data Packages, shall be deemed "Clinical Research Plan
Information" (as that term is defined in Section 7.1.1) and shall be owned
exclusively by IFM, and the provisions of Section 7.1.1 shall apply with respect
thereto. Notwithstanding the foregoing, to the extent any such data (including
raw data), information, results or analyses constitute or otherwise relate to
process development for the Clinical Candidate or Product, such data (including
raw data), information, results and analyses shall be deemed "Process
Development Technology" (as that term is defined in Section 7.1.2) and shall be
owned exclusively by VRGN, and the provisions of Section 7.1.2 shall apply with
respect thereto. 

     2.8 TERM AND TERMINATION OF THE CLINICAL RESEARCH PLAN. The Clinical
Research Plan shall commence on the Effective Date and, unless earlier
terminated as provided in this Agreement, continue until Regulatory Approval for
the Product in the United States has been granted by the FDA; provided, however,
that VRGN may, at its sole option, elect to terminate the Clinical Research Plan

                                       10

with or without cause at any time upon written notice to IFM. If VRGN elects to
terminate the Clinical Research Plan under this Section 2.8, this Agreement
shall be terminated in accordance with and subject to Article 10.

     2.9 COMPLIANCE WITH LAWS. IFM shall at all times comply fully with, and
shall ensure that its employees, agents and contractors comply fully with, the
FD&C Act and all other laws, regulations, rules, guidances, orders and
regulatory requirements applicable to the performance of IFM's obligations under
the Clinical Research Plan and this Agreement, including without limitation all
laws, regulations, rules, guidances, orders and regulatory requirements relating
to environmental, health and safety matters.

                                    ARTICLE 3

ELECTION TO PURSUE FURTHER CLINICAL RESEARCH AND NDA APPROVAL; MANUFACTURE BY
VRGN

     3.1 PHASE II AND PHASE III ELECTIONS BY VRGN.

     3.1.1 Following execution of this Agreement, IFM shall at its sole risk and
expense as provided for in the Budget, complete the Phase 1/2 clinical trial for
the Clinical Candidate as set forth in the Clinical Research Plan (including the
Budget and Schedule therefor), in accordance with and subject to the terms and
conditions of this Agreement.

     (a) If such Phase 1/2 clinical trial cannot be completed within the
Schedule and/or Budget therefor (as set forth in the Clinical Research Plan),
IFM shall immediately notify the CRMC and provide to the CRMC a proposed revised
Budget and Schedule to the Clinical Research Plan setting forth the additional
monies and time required to complete the Phase 1/2 clinical trial in accordance
with the Clinical Research Plan. Within thirty (30) days after the CRMC has
accepted the revised Budget and Schedule to the Clinical Research Plan for the
completion of the Phase 1/2 clinical trial, VRGN shall have the right, but not
the obligation, to provide (or cause to be provided) the additional monies
required to complete the Phase 1/2 clinical trial based upon such revised Budget
and Schedule, subject to the valuation of IFM at such time as determined under
Section 3.1.5(b)(i).

     (b) If such Phase 1/2 clinical trial is completed according to the Clinical
Research Plan, then within one hundred twenty (120) days after its completion,
IFM shall forward to VRGN a final Data Package containing all data, information
and results (and analyses thereof) relating to or arising out of such Phase 1/2
clinical trial, in a 

                                       11
<PAGE>   12
form that meets FDA's requirements relating to the preparation and submission of
INDs and NDAs. After receipt of such Data Package, VRGN shall have seven (7)
months within which to notify IFM in writing of VRGN's election in its sole
discretion to have IFM conduct one (1) Phase 3 clinical trial for the Clinical
Candidate in accordance with the Clinical Research Plan and this Agreement (the
"Phase II Election"). During such seven (7) month period, without further notice
from VRGN, IFM shall at its own expense as provided for in the Budget: (i)
prepare a protocol for such Phase 3 clinical trial, (ii) set up, hold meetings
and negotiate with the FDA regarding such Phase 3 clinical trial, and (iii)
prepare a supplement to the IND for the Clinical Candidate to submit to the FDA
for such Phase 3 clinical trial.

     (c) If VRGN does not exercise the Phase II Election by the end of such
seven (7) month period, and IFM obtains a bona fide firm written commitment from
a Third Party principal investor (a "Third Party Commitment") to fund a Phase 3
clinical trial for the Clinical Candidate (which Third Party Commitment shall be
submitted by IFM to the CRMC for its review), this Agreement shall terminate in
accordance with and subject to Article 10. Until IFM obtains a Third Party
Commitment to fund a Phase 3 clinical trial for the Clinical Candidate, VRGN
shall have the right to exercise the Phase II Election and this Agreement shall
remain in full force and effect. Notwithstanding the foregoing, if: (i) VRGN
does not exercise the Phase II Election by the end of such seven (7) month
period, (ii) IFM obtains a Third Party Commitment to fund a Phase 3 clinical
trial for the Clinical Candidate, and (iii) the terms of the definitive
agreement between IFM and such Third Party are materially more favorable to such
third party than those terms which were originally set forth in the Third Party
Commitment from such Third Party (which definitive agreement shall be provided
by IFM to VRGN for verification purposes under conditions of confidentiality),
then VRGN shall have the right (but not the obligation) to exercise the Phase II
Election within 30 days of the date IFM provides such definitive agreement to
VRGN, in which case this Agreement shall continue in full force and effect but
under the terms offered to such Third Party (if more favorable than those
provided for in this Agreement).

     (d) If VRGN does not exercise the Phase II Election by the end of such
seven (7) month period because VRGN believes one or more additional Phase 1 or 2
or Phase 1/2 clinical trials should be conducted before a Phase 3 clinical trial
for the Clinical Candidate is conducted (including but not limited to repeating
the Phase 1/2 clinical trial), then IFM shall provide to the CRMC a proposed
revised Budget and Schedule to the Clinical Research Plan setting forth the
additional monies and time required to complete such additional or repeated
clinical trial(s) in accordance with the Clinical Research Plan. Within ninety
(90) days after the CRMC has accepted the revised Budget and Schedule to the
Clinical Research Plan for the conduct of such additional or repeated clinical
trial(s), VRGN shall have the right, but not the obligation, to provide (or

                                       12
<PAGE>   13
cause to be provided) the additional monies required to conduct such additional
or repeated clinical trial(s) based upon such revised Budget and Schedule,
subject to the valuation of IFM at such time as determined under Section
3.1.5(b)(i). If VRGN provides (or causes to be provided) the additional monies
required to conduct any such additional or repeated clinical trial(s), then the
Clinical Research Plan shall be amended by the CRMC accordingly, IFM shall
supplement and obtain FDA approval for the supplemented IND for the Clinical
Candidate, and IFM shall perform such additional or repeated clinical trial(s)
in accordance with the Clinical Research Plan and in accordance with and subject
to this Agreement. If VRGN does not provide (or cause to be provided) the
additional monies required to conduct any such additional or repeated clinical
trial(s), and IFM obtains a Third Party Commitment to fund such additional or
repeated clinical trial(s) (which Third Party Commitment shall be submitted by
IFM to the CRMC for its review), this Agreement shall terminate in accordance
with and subject to Article 10. Until IFM obtains a Third Party Commitment to
fund such additional or repeated clinical trial(s), VRGN shall have the right to
exercise the Phase II Election and this Agreement shall remain in full force and
effect. Notwithstanding the foregoing, if: (i) VRGN does not provide (or cause
to be provided) the additional monies required to conduct any such additional or
repeated clinical trial(s), (ii) IFM obtains a Third Party Commitment to fund
such additional or repeated clinical trial(s), and (iii) the terms of the
definitive agreement between IFM and such Third Party are materially more
favorable to such Third Party than those terms which were originally set forth
in the Third Party Commitment from such Third Party (which definitive agreement
shall be provided by IFM to VRGN for verification purposes under conditions of
confidentiality), then VRGN shall have the right (but not the obligation) to
provide (or cause to be provided) within 30 days of the date IFM provides such
definitive agreement to VRGN, the additional monies required to conduct any such
additional or repeated clinical trial(s), in which case this Agreement shall
continue in full force and effect but under the terms offered to such Third
Party (if more favorable than those provided for in this Agreement). 

     (e) If VRGN funds additional or repeated clinical trial(s) under Section
3.1.1(d), then within one hundred twenty (120) days after the completion of any
such additional or repeated clinical trial(s), a Data Package containing all
data, information and results (and analyses thereof) relating to or arising out
of such additional or repeated clinical trial(s) shall be submitted by IFM to
the CRMC for its review in a form that meets FDA's requirements relating to the
preparation and submission of INDs and NDAs. VRGN shall, within seven (7) months
after the submission of such Data Package to the CRMC, have the right (but not
the obligation) to exercise the Phase II Election, in which case IFM shall
conduct a Phase 3 clinical trial for the Clinical Candidate in accordance with
the Clinical Research Plan and this Agreement. VRGN's obligation to exercise
such Phase II Election under this Section 3.1.1(e) shall, however, 

                                       13
<PAGE>   14
be suspended if a dose-ranging study for the Clinical Candidate is conducted
pursuant to Section 3.1.1(f).

     (f) If within sixty (60) days after the submission of the Data Package
under Section 3.1.1(b) or Section 3.1.1(e) to the CRMC, the CRMC determines that
a dose-ranging study for the Clinical Candidate is to be conducted before
commencement of a Phase 3 clinical trial, then IFM shall provide to the CRMC a
Budget and Schedule for such dose-ranging study. VRGN shall have the right, but
not the obligation, to elect to fund (or cause to be funded) such dose-ranging
study in accordance with Section 3.1.5(c) within one hundred twenty (120) days
after the acceptance by the CRMC of such Budget and Schedule for the
dose-ranging study. If VRGN elects to fund (or cause to be funded) such
dose-ranging study in accordance with Section 3.1.5(c): (i) the Clinical
Research Plan shall be amended by the CRMC to include the conduct and completion
of one (1) dose-ranging study for the Clinical Candidate, (ii) IFM shall prepare
the protocol for such dose-ranging study, (iii) IFM shall set up, hold meetings
and negotiate with the FDA regarding such dose-ranging study, (iv) IFM shall
prepare a supplement to the IND for the Clinical Candidate to submit to the FDA
for such dose-ranging study, in a manner that meets FDA's requirements relating
to the preparation and submission of INDs and NDAs, and shall obtain FDA
approval for the supplemented IND, and (v) IFM shall conduct such dose-ranging
study in accordance with the Clinical Research Plan (including the Schedule and
Budget therefor) and in accordance with and subject to this Agreement. Within
one hundred twenty (120) days after the completion of such dose-ranging study, a
Data Package containing all data, information and results (and analyses thereof)
relating to or arising out of such dose-ranging study shall be submitted by IFM
to the CRMC for its review in a form that meets FDA's requirements relating to
the preparation and submission of INDs and NDAs. VRGN shall, within seven (7)
months after the submission of such Data Package to the CRMC, have the right
(but not the obligation) to exercise the Phase II Election. If VRGN does not
elect to fund (or cause to be funded) such dose-ranging study, subject to
Section 3.1.5(c), this Agreement shall terminate in accordance with and subject
to Article 10. 

     (g) If VRGN does not agree that a protocol prepared by IFM for any clinical
trial or study to be conducted pursuant to this Article 3 is necessary and
appropriate with respect to its scope or size (such as, for example, VRGN
believes the trial or study for which the protocol is designed is unnecessarily
large or expensive), VRGN shall have the right to require the Parties to submit
the issue to a single independent Third Party mutually acceptable to the Parties
(the "Arbitrator") for resolution. The Arbitrator shall have considerable
experience in the business, clinical and regulatory development of
biopharmaceutical products, including without limitation the design of protocols
for human clinical trials for such products. The decision of the Arbitrator
shall be binding on the Parties for the purposes hereof, such that if the

                                       14
<PAGE>   15
Arbitrator decides that a protocol prepared by IFM for any clinical trial or
study to be conducted pursuant to this Article 3 is necessary and appropriate in
scope and size, such protocol may be used by IFM for such clinical trial or
study. If, however, the Arbitrator decides there are aspects of a protocol
prepared by IFM for any clinical trial or study to be conducted pursuant to this
Article 3, which are not necessary or appropriate, such protocol shall be
subject to VRGN's approval. The arbitration shall be held in a place to be
mutually agreed by VRGN and IFM, according to the commercial rules of the
American Arbitration Association (the "AAA"), and the Parties shall share
equally the costs of such arbitration under this Section 3.1.1(g). 

     3.1.2 If VRGN exercises the Phase II Election under Section 3.1.1: (i) the
Clinical Research Plan shall be amended by the CRMC to include the conduct and
completion of one (1) Phase 3 clinical trial for the Clinical Candidate, (ii)
VRGN shall provide the funding required (or cause such funding to be provided),
for IFM to conduct one (1) Phase 3 clinical trial for the Clinical Candidate in
accordance with the Clinical Research Plan; provided, however, that if a
dose-ranging study is included in such Phase 3 clinical trial, Section 3.1.5(a)
or Section 3.1.5(b)(i) shall apply with respect to the incremental additional
costs to conduct the dose-ranging study as part of such Phase 3 clinical trial,
which incremental additional costs are paid by VRGN in funding such Phase 3
clinical trial pursuant to the Phase II Election, (iii) IFM shall supplement, in
a manner that meets FDA's requirements relating to the preparation and
submission of INDs and NDAs, and obtain FDA approval for the supplemented IND
for the Clinical Candidate, and (iv) IFM shall conduct such Phase 3 clinical
trial in accordance with the Clinical Research Plan (including the Schedule and
Budget therefor) and in accordance with and subject to this Agreement.

     (a) If such Phase 3 clinical trial cannot be completed within the Schedule
and/or Budget therefor (as set forth in the Clinical Research Plan), IFM shall
immediately notify the CRMC and provide to the CRMC a proposed revised Budget
and Schedule to the Clinical Research Plan setting forth the additional monies
and time required to complete the Phase 3 clinical trial in accordance with the
Clinical Research Plan. Within one hundred eighty (180) days after the CRMC has
accepted the revised Budget and Schedule to the Clinical Research Plan for the
completion of the Phase 3 clinical trial, VRGN shall have the right, but not the
obligation, to provide (or cause to be provided) the additional monies required
to complete the Phase 3 clinical trial based upon such revised Budget and
Schedule, subject to the valuation of IFM at such time as determined under
Section 3.1.5(b)(i).

     (b) If such Phase 3 clinical trial is completed according to the Clinical
Research Plan, then within one hundred twenty (120) days after its completion,
IFM shall forward to VRGN a final Data Package containing all data, information
and 

                                       15
<PAGE>   16
results (and analyses thereof) relating to or arising out of such Phase 3
clinical trial in a form that meets FDA's requirements relating to the
preparation and submission of INDs and NDAs. After receipt of such Data Package,
VRGN shall have nine (9) months within which to notify IFM in writing of VRGN's
election, in its sole discretion, to prepare and submit to the FDA an NDA for
the Clinical Candidate (the "Phase III Election"). Upon the exercise by VRGN of
the Phase III Election, the Clinical Candidate shall be deemed to be a Product.
During such nine (9) month period, upon VRGN's request and at VRGN's direction,
IFM shall, at its own expense as provided for in the Budget: (i) fully cooperate
and assist VRGN with the preparation and submission of such NDA to the FDA; and
(ii) participate in meetings and negotiations with the FDA regarding the
preparation and submission of such NDA.

     (c) If VRGN does not exercise the Phase III Election by the end of such
nine (9) month period because VRGN believes one or more additional clinical
trials should be conducted before an NDA for the Product is submitted with the
FDA (including but not limited to repeating the Phase 3 clinical trial), then
IFM shall provide to the CRMC a proposed revised Budget and Schedule to the
Clinical Research Plan setting forth the additional monies and time required to
complete such additional or repeated clinical trial(s) in accordance with the
Clinical Research Plan. Within one hundred eighty (180) days after the CRMC has
accepted the revised Budget and Schedule to the Clinical Research Plan for the
conduct of such additional or repeated clinical trials, VRGN shall have the
right, but not the obligation, to provide (or cause to be provided) the
additional monies required to conduct such additional or repeated clinical
trials based upon such revised Budget and Schedule, subject to the valuation of
IFM at such time as determined under Section 3.1.5(b)(i). If VRGN provides (or
causes to be provided) the additional monies required to conduct any such
additional or repeated clinical trial(s), then the Clinical Research Plan shall
be amended by the CRMC accordingly, IFM shall supplement, and obtain approval
from the FDA for the supplemented IND for the Clinical Candidate, and IFM shall
perform such additional or repeated clinical trial(s) in accordance with the
Clinical Research Plan and in accordance with and subject to this Agreement. If
VRGN does not provide (or cause to be provided) the additional monies required
to conduct such additional or repeated clinical trial(s), and IFM obtains a
Third Party Commitment to fund such additional or repeated clinical trial(s)
(which Third Party Commitment shall be submitted by IFM to the CRMC for its
review), this Agreement shall terminate in accordance with and subject to
Article 10. Until IFM obtains a Third Party Commitment to fund such additional
or repeated clinical trial(s), VRGN shall have the right to exercise the Phase
III Election and this Agreement shall remain in full force and effect.
Notwithstanding the foregoing, if: (i) VRGN does not provide (or cause to be
provided) the additional monies required to conduct any such additional or
repeated clinical trial(s), (ii) IFM obtains a Third Party Commitment to fund
such additional or 

                                       16
<PAGE>   17
repeated clinical trial(s), and (iii) the terms of the definitive agreement
between IFM and such Third Party are materially more favorable to such Third
Party than those terms which were originally set forth in the Third Party
Commitment from such Third Party (which definitive agreement shall be provided
by IFM to VRGN for verification purposes under conditions of confidentiality),
then VRGN shall have the right (but not the obligation) to provide (or cause to
be provided) the additional monies required to conduct such additional or
repeated clinical trial(s) within 30 days of the date IFM provides such
definitive agreement to VRGN, in which case this Agreement shall continue in
full force and effect but under the terms offered to such Third Party (if more
favorable than those provided for in this Agreement).

     (d) If VRGN provides (or causes to be provided) the additional monies
required to conduct any additional or repeated clinical trial(s) under Section
3.1.2(c), then within one hundred twenty (120) days after the completion of any
such additional or repeated clinical trial(s), a Data Package containing all
data, information and results (and analyses thereof) relating to or arising out
of such additional or repeated clinical trial(s) shall be submitted by IFM to
the CRMC for its review in a form that meets FDA's requirements relating to the
preparation and submission of INDs and NDAs. VRGN shall thereupon (but not later
than nine (9) months after the submission of such Data Package to the CRMC) have
the right (but not the obligation) to exercise the Phase III Election and, upon
VRGN's request and at VRGN's direction, IFM shall, at its own expense as
provided for in the Budget: (i) fully cooperate and assist VRGN with the
preparation and submission of such NDA to the FDA; and (ii) participate in
meetings and negotiations with the FDA regarding the preparation and submission
of such NDA. 

     3.1.3 If VRGN exercises the Phase III Election under Section 3.1.2: (i) IFM
shall compile at its own expense as provided for in the Budget, a final report
of all Data Packages, in a form that meets FDA's requirements relating to the
preparation and submission of INDs and NDAs, within one hundred twenty (120)
days after the Phase III Election by VRGN under Section 3.1.2, and (ii) VRGN
shall at its own expense prepare and submit an NDA for the Product with the FDA
and seek to obtain FDA approval for such NDA for IFM. The obligations of IFM
under Section 3.1.3(i) shall be undertaken by IFM in accordance with the
Clinical Research Plan (including within the Budget therefor) and in accordance
with and subject to this Agreement. If compiling a final report of all Data
Packages, in a form that meets FDA's requirements relating to the preparation
and submission of INDs and NDAs, exceeds the Budget therefor or takes longer
than one hundred twenty (120) days, IFM shall immediately notify the CRMC and
provide to the CRMC a proposed revised Budget and Schedule to the Clinical
Research Plan setting forth the additional monies and time required to complete
the compilation of a final report of all Data Packages, in a form that meets
FDA's requirements relating to the preparation and submission of INDs and NDAs,
in accordance with the Clinical 

                                       17
<PAGE>   18
Research Plan. Within one hundred twenty (120) days after the CRMC has
accepted the revised Budget and Schedule to the Clinical Research Plan for such
compilation of a final report of all Data Packages, VRGN shall have the right,
but not the obligation, to provide (or cause to be provided) the additional
monies required to complete such compilation of a final report of all Data
Packages, subject to the valuation of IFM at such time as determined under
Section 3.1.5(b)(i).

     3.1.4 In connection with preparing and submitting the NDA for the Product
with the FDA, and seeking to obtain and obtaining FDA approval for such NDA,
VRGN shall at all times be deemed to be acting on behalf of IFM (which shall be
the Sponsor of the Product and owner of the NDA for the Product), and all
documents relating to the Product shall refer to IFM as the Sponsor thereof and
owner of the NDA for the Product. The CRMC shall be informed on a regular basis
of the status of the NDA approval process. With respect to the NDA for the
Product, VRGN shall be responsible for all submissions to the FDA relating to
the Product (including without limitation the NDA), all correspondence and other
communications to the FDA, and any and all communications (including meetings,
negotiations and telephone calls) with the FDA, provided that IFM shall have the
right to review and comment upon all such submissions, correspondence and other
communications, and shall have the right to participate in any meetings,
negotiations and telephone calls with the FDA. 

     3.1.5 Notwithstanding any other provision of this Article 3, if VRGN
elects, under Sections 3.1.1(a), 3.1.1(d), 3.1.1(f), 3.1.2(a), 3.1.2(c) or
3.1.3, to provide (or cause to be provided) to IFM additional monies (as
provided for in a revised Budget and Schedule to the Clinical Research Plan) for
IFM to: (i) complete a clinical trial(s), (ii) perform an additional or repeated
study and/or clinical trial(s), including without limitation a dose-ranging
study if required pursuant to Section 3.1.1(f), and/or (iii) compile a final
report of all Data Packages in accordance with Section 3.1.3, then in each such
case, at the sole option of VRGN after consultations with IFM, either: 

     (a) VRGN shall provide such additional monies to IFM as a secured lender;
and/or

     (b) IFM shall issue to VRGN additional shares of IFM Series A Convertible
Preferred Stock in consideration therefor. The purchase price at which such
additional shares shall be issued shall be determined, on a case-by-case basis,
as follows:

     (i) Except in the event where additional monies to fund a dose-ranging
study may be required pursuant to Section 3.1.1(f), which event is addressed in
Section 3.1.5(c) below, the Parties shall negotiate in good faith at such time
the per share purchase price of such IFM Series A Convertible Preferred Stock.
If the Parties are 

                                       18
<PAGE>   19
unable to agree upon such per share purchase price within thirty (30) days after
the CRMC has accepted a revised Budget and Schedule to the Clinical Research
Plan for the: (A) completion of clinical trial(s), (B) performance of an
additional or repeated study and/or clinical trial(s), and/or (C) compilation of
a final report of all Data Packages in accordance with Section 3.1.3 (as the
case may be), the Parties shall select a mutually acceptable independent Third
Party (the "Appraiser") to make a then-current valuation of IFM for such purpose
(the "IFM Valuation"). VRGN shall have the right, but not the obligation, within
one hundred twenty (120) days after the determination of the IFM Valuation by
the Appraiser, to purchase additional shares of IFM Series A Convertible
Preferred Stock based on the determination of the IFM Valuation by such
Appraiser. If VRGN decides to purchase additional shares of IFM Series A
Convertible Preferred Stock based on the determination of such Appraiser, the
per share purchase price of such Stock shall be the IFM Valuation, divided by
the total number of issued and convertible, exchangeable or exercisable for
shares of IFM common stock (on a fully-diluted basis) outstanding immediately
prior to payment of additional monies by VRGN under this Section 3.1.5(b). Upon
such payment , IFM shall issue to VRGN such number of shares equal to the amount
of additional monies provided by VRGN in such case, divided by the per share
purchase price.

     (ii) If VRGN decides not to provide (or cause to be provided) additional
monies to IFM as a secured lender under Section 3.1.5(a), or does not purchase
additional shares of IFM Series A Convertible Preferred Stock pursuant to
Section 3.1.5(b)(i), then IFM shall have the right to obtain Third Party
financing as the funding source to: (A) complete clinical trial(s), (B) perform
additional or repeated study(ies) and/or clinical trial(s), and/or (C) compile a
final report of all Data Packages in accordance with Section 3.1.3, as the case
may be. Notwithstanding the foregoing, IFM shall not obtain Third Party
financing as the funding source for such additional monies under this Section
3.1.5(b)(ii) where the aggregate consideration, in whatever form, proposed to be
paid by such Third Party to IFM for such Third Party financing is more favorable
than the IFM Valuation as determined by the Appraiser, without first providing
VRGN a right to first refusal to provide such additional monies to IFM on the
same terms as in the proposed Third Party financing. In such event, IFM shall
provide VRGN with the terms of the proposed Third Party financing and within 30
days VRGN shall determine whether to exercise its right of first refusal
hereunder. If VRGN refuses to provide (or cause to be provided) the additional
monies at the terms of such proposed Third Party financing, then IFM shall have
the right to obtain such Third Party financing as the funding source for the
activities described herein. 

     (iii) If as a result of circumstances within the reasonable control of IFM
(and not due to the material breach, material default, negligence or willful
misconduct of VRGN or other action of VRGN that prevents IFM from exercising
such 

                                       19
<PAGE>   20
reasonable control), including a material breach or material default in the
conduct of the original Phase 1/2 clinical trial or in IFM's performance of this
Agreement, or the negligence or willful misconduct of IFM, additional monies are
required under Section 3.1.1(a) or 3.1.1(d) for IFM to complete a clinical trial
or perform an additional or repeated study and/or clinical trial(s), then the
per share purchase price of such additional shares of IFM Series A Convertible
Preferred Stock shall be eighty percent (80%) of the valuation of IFM
immediately prior to the date on which the Phase II Election must be exercised
(the "Pre-Phase II Election IFM Valuation"), divided by the total number of
issued and convertible, exchangeable or exercisable for shares of IFM common
stock (on a fully-diluted basis) outstanding immediately prior to payment of
additional monies by VRGN under this Section 3.1.5(b). Such valuation shall be
made by mutual agreement of the Parties or by an Appraiser in accordance with
Section 3.1.5(b)(i). Upon such payment, IFM shall issue to VRGN such number of
shares equal to the amount of additional monies provided by VRGN in such case,
divided by the per share purchase price. 

     (iv) If as a result of circumstances within the reasonable control of IFM
(and not due to the material breach, material default, negligence or willful
misconduct of VRGN or other action of VRGN that prevents IFM from exercising
such reasonable control), including a material breach or material default in the
conduct of the original Phase 3 clinical trial or in IFM's performance of this
Agreement, or the negligence or willful misconduct of IFM, additional monies are
required under Section 3.1.2(a) or 3.1.2(c) for IFM to perform an additional or
repeated study and/or clinical trial(s), then the per share purchase price of
such additional shares of IFM Series A Convertible Preferred Stock shall be
eighty percent (80%) of the valuation of IFM immediately prior to the date on
which the Phase III Election must be exercised (the "Pre-Phase III Election IFM
Valuation"), divided by the total number of issued and convertible, exchangeable
or exercisable for shares of IFM common stock (on a fully-diluted basis)
outstanding immediately prior to payment of additional monies by VRGN under this
Section 3.1.5(b). Such valuation shall be made by mutual agreement of the
Parties or by an Appraiser in accordance with Section 3.1.5(b)(i). Upon such
payment, IFM shall issue to VRGN such number of shares equal to the amount of
additional monies provided by VRGN in such case, divided by the per share
purchase price. 

     (v) If as a result of circumstances within the reasonable control of IFM
(and not due to the material breach, material default, negligence or willful
misconduct of VRGN or other action of VRGN that prevents IFM from exercising
such reasonable control), including a material breach or material default in
IFM's performance of its obligations under Section 3.1.3 or this Agreement, or
the negligence or misconduct of IFM, additional monies are required under
Section 3.1.3 for IFM to compile a final report of all Data Packages, in a form
that meets FDA's requirements relating to the 

                                       20
<PAGE>   21
preparation and submission of INDs and NDAs, within one hundred twenty (120)
days after the Phase III Election by VRGN under Section 3.1.2, then the per
share purchase price of such additional shares of IFM Series A Convertible
Preferred Stock shall be eighty percent (80%) of the valuation of IFM
immediately following the date on which the Phase III Election was exercised
(the "Post-Phase III Election IFM Valuation"), divided by the total number of
issued and convertible, exchangeable or exercisable for shares of IFM common
stock (on a fully-diluted basis) outstanding immediately prior to payment of
additional monies by VRGN under this Section 3.1.5(b). Such valuation shall be
made by mutual agreement of the Parties or by an Appraiser in accordance with
Section 3.1.5(b)(i). Upon such payment, IFM shall issue to VRGN such number of
shares equal to the amount of additional monies provided by VRGN in such case,
divided by the per share purchase price.

     (vi) In consideration of the substantial investment by VRGN in IFM through
the exercise of the Phase II Election by VRGN, it is agreed that if at any time
after the Phase II Election by VRGN (provided that VRGN has provided, or has
caused to be provided, the additional monies to fund the Phase 3 clinical trial
through the purchase of capital stock of IFM (i.e., for securities that are
either IFM capital stock or are convertible into IFM capital stock)), IFM
commits a material breach or defaults in the performance of its obligations
under this Agreement, or is otherwise negligent or engages in willful misconduct
and, at such time, a majority of the directors of the Board of Directors of IFM
has not been appointed by VRGN, then IFM shall take all necessary steps to
reconstitute the Board of Directors of IFM, such that a majority of its members
shall be appointed by VRGN.

     (vii) For the purposes of this Section 3.1.5, a material breach or material
default shall include without limitation IFM's or its employees', agents' or
contractors' inability to complete a clinical trial or study (as the case may
be) within the Budget and/or Schedule therefor; provided such inability was
within IFM's or its employees', agents' or contractors' reasonable control, and
not due to the material breach, material default, negligence or willful
misconduct of VRGN or other action of VRGN that prevents IFM from exercising
such reasonable control. 

     (c) The Parties acknowledge and agree that as of the Effective Date, the
valuation of IFM is eleven million, five hundred thousand dollars ($11,500,000),
which amount shall be referred to herein as the "Original IFM Valuation". If,
pursuant to Section 3.1.1(f), the CRMC determines that a dose-ranging study for
the Clinical Candidate is to be conducted before commencement of a Phase 3
clinical trial, and VRGN elects, under Section 3.1.1(f), to provide (or cause to
be provided) to IFM the additional monies (as provided for in a Budget and
Schedule to the Clinical Research Plan) required for IFM to conduct such
dose-ranging study, then VRGN shall either 

                                       21
<PAGE>   22
provide (or cause to be provided) such monies to IFM as a secured lender under
Section 3.1.5(a), or purchase additional shares of IFM Series A Convertible
Preferred Stock based on the Original IFM Valuation, such that the per share
purchase price of such Stock shall be the Original IFM Valuation, divided by the
total number of issued and convertible, exchangeable or exercisable for IFM
common stock (on a fully-diluted basis) outstanding immediately prior to payment
of additional monies by VRGN under this Section 3.1.5(c). Upon such payment, IFM
shall issue to VRGN such number of shares equal to the amount of additional
monies provided (or caused to be provided) by VRGN in such case, divided by the
per share purchase price. If VRGN decides not to fund (or cause to be funded)
the dose-ranging study pursuant to Section 3.1.1(f), then IFM shall have the
right to obtain Third Party financing to fund such dose-ranging study.
Notwithstanding the foregoing, IFM shall not obtain Third Party financing as the
funding source for such additional monies under this Section 3.1.5(c) where the
aggregate consideration, in whatever form, proposed to be paid by such Third
Party to IFM for such Third Party financing is more favorable than the Original
IFM Valuation, without first providing VRGN a right to first refusal to provide
such additional monies to IFM on the same terms as in the proposed Third Party
financing. In such event, IFM shall provide VRGN with the terms of the proposed
Third Party financing and within 30 days VRGN shall determine whether to
exercise it s right of first refusal hereunder. If VRGN refuses to provide (or
cause to be provided) the additional monies at the terms of such proposed Third
Party financing, then IFM shall have the right to obtain such Third Party
financing as the funding source for such dose-ranging study.

     3.1.6 IFM shall promptly notify VRGN in writing if, at any time, IFM
obtains financing from a Third Party to fund: (a) a Phase 3 clinical trial for
the Clinical Candidate, (b) the preparation or submission of an NDA to the FDA
for the Product, (c) obtaining FDA approval for such NDA, (d) completion of
clinical trial(s), (e) performance of additional or repeated study(ies) and/or
clinical trial(s), including without limitation a dose-ranging study if required
pursuant to Section 3.1.1(f), and/or (f) compilation of a final report of all
Data Packages in accordance with Section 3.1.3.

     3.1.7 IFM shall, on a monthly basis, submit to VRGN financial information,
in form and content mutually acceptable to the Parties, evidencing all fees,
costs and expenses incurred by IFM in connection with carrying out its
obligations under the Clinical Research Plan in accordance with the Budget
(including without limitation the conduct of studies and/or clinical trials).
VRGN or its representatives shall have the right, on an annual basis during
regular business hours and upon reasonable advance notice, during the term
hereof and for a period of two (2) years thereafter, to examine IFM's books and
records for the purpose of verifying all such fees, costs and expenses.

                                       22

     3.1.8 IFM will own: (i) any and all NDA(s) for Product and any equivalent
marketing approval applications, and all Regulatory Approvals for Product in
every country and territory in the world (excluding Regulatory Approvals for the
manufacture of Product, which shall be owned by VRGN), and (ii) except for that
data (including raw data), information and results (including analyses thereof)
constituting or otherwise relating to Process Development Technology (as that
term is defined herein), all data (including raw data), information and results
(including analyses thereof) contained in such NDA(s) and other Regulatory
Approvals and the provisions of Section 7.1.2 shall apply with respect thereto.

                          3.2 MANUFACTURE BY VIRAGEN.

     3.2.1 Pursuant to the grant of licenses and other rights under Article 5,
VRGN shall at all times, subject to granting license(s) to Product Marketers (as
that term is defined in Section 3.2.5) or other Third Parties pursuant to
Sections 3.2.6, 3.2.7 or 3.2.8, have exclusive rights in the Territory with
respect to the manufacture and supply of Product and exclusive control over the
manufacture and supply of Product for use, distribution or sale anywhere in the
Territory. Accordingly, subject to granting license(s) to Product Marketers or
other Third Parties pursuant to Sections 3.2.6, 3.2.7 or 3.2.8, VRGN shall be
the exclusive manufacturer and supplier of all Product for use, distribution or
sale anywhere in the Territory, including without limitation all Product
required for: (i) research and development purposes, (ii) Regulatory Approval
purposes with regulatory authorities anywhere in the Territory, (iii)
pre-clinical and clinical trials (both before and after Product Regulatory
Approval), (iv) samples for distribution to physicians and other health care
professionals, and (v) commercial distribution and sale.

     3.2.2 The Parties acknowledge that as of the Effective Date, IFM is engaged
in discussions with Japanese pharmaceuticals companies regarding the possible
licensing by IFM to a Japanese pharmaceuticals company of rights to develop,
register, manufacture, market, sell, distribute and commercialize in Japan the
Clinical Candidate that exists as of the Effective Date. IFM hereby agrees to
grant to VRGN, without additional consideration of any kind, exclusive rights in
Japan with respect to the manufacture and supply of Product, and exclusive
control over the manufacture and supply of Product for use, distribution or sale
in Japan if, within two (2) years after the Effective Date, IFM does not enter
into a definitive written agreement with a Japanese pharmaceuticals company
pursuant to which IFM grants to such Japanese pharmaceuticals company exclusive
rights with respect to the development, registration, manufacture and
commercialization in Japan of the Clinical Candidate that exists as of the
Effective Date. IFM agrees that it shall not, in any discussions with Third
Parties 

                                       23
<PAGE>   24
including Japanese pharmaceuticals companies, discuss or disclose any
Confidential Information of VRGN, including without limitation, Process
Development Technology. 

     3.2.3 Upon the grant by IFM to VRGN of the exclusive rights in Japan with
respect to the manufacture and supply of the Product pursuant to Section 3.2.2,
VRGN shall be the exclusive manufacturer and supplier of all Product for use,
distribution or sale in Japan, including without limitation all Product required
for: (i) research and development purposes, (ii) Regulatory Approval purposes
with regulatory authorities anywhere in Japan, (iii) pre-clinical and clinical
trials in Japan (both before and after Product Regulatory Approval), (iv)
samples for distribution to physicians and other health care professionals in
Japan, and (v) commercial distribution and sale in Japan.

     3.2.4 VRGN will be responsible for all direct and indirect costs and
expenses related to: (i) pilot plant or small-scale manufacturing of the
Product, (ii) scale-up and qualification for commercial manufacturing of the
Product, and (iii) obtaining all licenses, permits and authorizations for those
facilities where the Product is manufactured. VRGN shall have the right, in its
sole discretion, to subcontract to Affiliates and Third Parties certain
activities in the manufacture of Product including without limitation
formulation and fill and packaging and labeling of Product. In the case of such
subcontracting by VRGN, VRGN assumes full responsibility and liability for the
performance of its subcontractors in carrying out such activities. VRGN shall
defend, indemnify and hold harmless IFM and its Affiliates (excluding VRGN) and
their respective directors (excluding VRGN representatives), officers, agents
and employees, successors and assigns from and against any and all liabilities,
claims, actions, suits, damages, losses, costs and expenses, fines and penalties
(including without limitation attorney's fees and other costs of litigation,
regardless of outcome) arising out of or related to the manufacture of Product
(including without limitation the formulation and fill and packaging and
labeling of Product) by Third Parties or Affiliates of VRGN (excluding IFM)
pursuant to subcontracts with VRGN. VRGN shall cause the manufacture of Product
and, to the extent any external financing is obtained in connection therewith,
such financing shall be obtained without diluting the then-current stockholders
of IFM.

     3.2.5 VRGN shall supply Product to IFM and its Affiliates, partners,
distributors, licensees and other Third Parties having rights with respect to
the distribution, marketing or sale of Product in the Territory (and Japan if
VRGN obtains exclusive rights with respect to the exclusive manufacture and
supply of Product in Japan under Section 3.2.2) (collectively, "Product
Marketers"). VRGN's supply of Product to Product Marketers shall be subject to
the terms and conditions of arm's length Supply Agreements negotiated in good
faith between VRGN and such Product Marketers.

                                       24
<PAGE>   25
VRGN shall be the exclusive supplier of Product under any and all such Supply
Agreements (such that all Product Marketers shall purchase their entire
requirements of Product from VRGN), and the price of any Product supplied by
VRGN under such Supply Agreements shall be commercially reasonable.

     3.2.6 If it is determined pursuant to arbitration under Section 3.2.8, that
the price of any Product proposed to be supplied by VRGN to a Product Marketer
under a Supply Agreement, is not commercially reasonable, then at its option,
VRGN shall either supply Product to such Product Marketer at a price that is
determined to be commercially reasonable pursuant to such arbitration proceeding
or, within a reasonable time thereafter, VRGN and such Product Marketer shall
negotiate in good faith the grant of a license to such Product Marketer under
the Process Development Technology, for the sole purpose of using Process
Development Technology in the manufacture of Product. Notwithstanding the
foregoing, VRGN reserves the right to not grant a license to a Product Marketer
if VRGN reasonably believes such Product Marketer would not be able to meet its
obligations under the license, but in such event, VRGN shall supply Product to
such Product Marketer at the price determined to be commercially reasonable
pursuant to the arbitration proceeding under Section 3.2.8. 

     3.2.7 If this Agreement terminates pursuant to Sections 2.8, 3.1.1(c),
3.1.1(d) or 3.1.2(c), then at the request of IFM, VRGN and a Product Marketer
desiring to obtain a license from VRGN, will negotiate in good faith the grant
of a license under the Process Development Technology to such Product Marketer
for the sole purpose of using Process Development Technology in the manufacture
of Product. Notwithstanding the foregoing, VRGN reserves the right to not grant
a license to a Product Marketer if VRGN reasonably believes such Product
Marketer would not be able to meet its obligations under the license. In the
event VRGN does not grant a license to such Product Marketer for such reason,
IFM shall have the same rights to Process Development Technology that IFM would
have in a Chapter 7 bankruptcy case with respect to VRGN, where the license was
rejected by VRGN's trustee in bankruptcy pursuant to clauses (1)(B), (2) and (3)
of 11 U.S.C. Section 365(n) of the United States Bankruptcy Code. 

     3.2.8 Any license granted by VRGN pursuant to Sections 3.2.6 or 3.2.7,
shall be royalty-bearing and shall include other customary consideration given
to licensors under such license agreements, and shall contain other reasonable
commercial terms as agreed between VRGN and such Product Marketer, including
without limitation full indemnification in favor of VRGN. If VRGN and such
Product Marketer do not enter into a definitive license agreement after
negotiating in good faith for a period of one hundred twenty (120) days, because
VRGN and such Product Marketer have been unable to agree on the terms of such
license agreement, then the Product Marketer may request 

                                       25
<PAGE>   26
that the determination of such terms be submitted to and made by a single
independent Third Party mutually acceptable to the Parties (the "Arbitrator").
The Arbitrator under this Section 3.2.8 shall have considerable business
experience in the licensing of biopharmaceutical products, including without
limitation licensing of manufacturing rights for such products. The decision of
the Arbitrator shall be binding on the Parties for the purposes hereof, such
that VRGN shall grant a license under its Process Development Technology to such
Product Marketer or other Third Party, for the sole purpose of using Process
Development Technology in the manufacture of Product, containing terms
determined by the Arbitrator. The arbitration shall be held in a place to be
mutually agreed by VRGN and the Product Marketer or other Third Party, according
to the commercial rules of the AAA. VRGN and the Product Marketer or other Third
Party shall share equally the costs of arbitration under this Section 3.2.8.

                                   ARTICLE 4

                   PRODUCT AND PROCESS DEVELOPMENT BY VIRAGEN

     4.1 VRGN shall exercise commercially reasonable efforts, at its own
expense, to carry out process development for the Clinical Candidate and Product
during the term hereof. VRGN shall have exclusive control over and
responsibility for conducting any and all process development for the Clinical
Candidate and Product (including but not limited to process improvements). IFM
shall participate at VRGN's request with VRGN in carrying out any process
development for the Clinical Candidate and Product, and VRGN shall provide the
CRMC with quarterly summaries of VRGN's activities in carrying out process
development for the Clinical Candidate and Product. VRGN's activities in
carrying out process development for the Clinical Candidate and Product shall be
at the direction of the PDSC (defined below) and shall include the conduct of
comparability (equivalency) studies, stability studies and other such process
development required to support clinical trials and commercial manufacture of
Product as determined by the PDSC.

     4.2 In furtherance of VRGN's obligation to conduct process development for
the Clinical Candidate and Product under Section 4.1, VRGN shall establish a
Process Development Steering Committee (the "PDSC") which shall oversee the
conduct of process development for the Clinical Candidate and Product by VRGN.
Dr. Smart shall be a member of the PDSC. All of the other members of the PDSC
shall be appointed by VRGN in its sole discretion. Following the establishment
of the PDSC, the PDSC shall determine its functions, powers and governance,
frequency of its meetings, and other similar matters. 

                                       26
<PAGE>   27

     4.3 Notwithstanding Section 4.1, VRGN makes no representations or
warranties, express or implied, with respect to any process development for the
Clinical Candidate or Product that it undertakes hereunder. Accordingly, VRGN
neither represents nor warrants that its process development activities will
result in the successful development, registration or commercialization of the
Clinical Candidate or Product anywhere in the world, or the successful or
cost-effective manufacture of the Clinical Candidate or Product. If VRGN's
process development activities do not result in the successful or cost-effective
manufacture of the Clinical Candidate or Product, and IFM must use its own or a
Third Party's process technology for the manufacture of the Clinical Candidate
or Product, VRGN shall not own the process technology developed by IFM or such
Third Party; provided that any process technology developed by IFM or such Third
Party does not: (a) infringe or misappropriate Process Development Technology,
or (b) utilize IFM Technology. If this Agreement terminates and IFM desires to
acquire a license from VRGN to use the IFM Technology in developing IFM's own
process technology for the manufacture of the Clinical Candidate or Product, the
Parties shall negotiate in good faith the terms of a license agreement under
which VRGN would grant to IFM such license. If the Parties do not enter into a
definitive license agreement after negotiating in good faith for a period of one
hundred twenty (120) days, because VRGN and IFM have been unable to agree on the
value of the IFM Technology to be licensed thereunder, then IFM may request that
the determination of such value be submitted to and made by a single independent
Third Party mutually acceptable to the Parties (the "Arbitrator"). The
Arbitrator under this Section 4.3 shall have considerable business experience in
the licensing of biopharmaceutical products, including without limitation
licensing of manufacturing rights for such products. The decision of the
Arbitrator shall be binding on the Parties for the purposes hereof, such that
VRGN shall grant a license under the IFM Technology to IFM, for the sole purpose
of using IFM Technology in the manufacture of Product, based on a valuation of
the IFM Technology determined by the Arbitrator. The arbitration shall be held
in a place to be mutually agreed by the Parties, according to the commercial
rules of the AAA, and the Parties shall share equally the costs of arbitration
under this Section 4.3.

Candidate and Product, and analyses thereof, for the purposes of exercising its
rights under the licenses granted in Section 5.1 and carrying out its
obligations under this Agreement, including without limitation the registration
of Product in all countries of the Territory, and obtaining all licenses,
permits and authorizations for those facilities where Product is manufactured;
and

     5.2.2 A right of cross-reference to all Regulatory Approvals and regulatory
submissions for the Clinical Candidate and Product in the Territory, and access
to all underlying data for such Regulatory Approvals and regulatory submissions,
for the purposes of exercising its rights under the licenses granted in Section
5.1 and carrying out its obligations under this Agreement, including without
limitation the registration of Product in all countries of the Territory, and
obtaining all licenses, permits and authorizations for those facilities where

     5.2.3 Upon VRGN's request, IFM shall also provide to VRGN materials
(including without limitation any biological materials, chemical compounds or
substances, biological cells, cell lines and products generated thereby or
components thereof, whether derived from biological material or synthesized)
which may be used by VRGN for the purposes of exercising its rights under the
licenses granted in Section 5.1 and carrying out its obligations under this
Agreement. Immediately following the Effective Date, IFM shall commence
technology transfer of IFM Technology to VRGN on a timely basis, to effect the
purposes hereof. 

     5.3 EXCLUSIVE COLLABORATION. IFM covenants and agrees that during the term
of this Agreement it will not use, nor license, assign or transfer to any
Affiliate or Third Party, any IFM Technology or Clinical Research Plan
Information, or encumber such IFM Technology or Clinical Research Plan
Information, in any way that is inconsistent with the provisions in this
Agreement, without the prior written consent of VRGN, which may be withheld in
its sole discretion.

     5.4 NO IMPLIED LICENSES. By virtue of entering into this Agreement, no
licenses, express or implied, are being granted by VRGN to IFM or by 


                                       28
<PAGE>   29
IFM to VRGN and, other than as expressly provided for in Sections 3.2 and 5.1,
no license rights of any kind shall be created in either Party by implication or
estoppel.

     7.1.2 Any and all: (i) process developments relating to the Clinical
Candidate or Product, including without limitation any and all process
improvements, formulae, techniques, designs, methods, know-how and trade secrets
relating to the manufacture of the Clinical Candidate or Product, and (ii)
patent applications and patents on any or all of the foregoing (including
without limitation any divisions, continuations, continuations-in-part,
reissues, extensions, renewals, supplementary protection certificates and
foreign counterparts thereof) (collectively, the "Process Development
Technology") but excluding any IFM Technology, shall be owned exclusively by
VRGN, whether the Process Development Technology is conceived, made and reduced
to practice by VRGN alone, by IFM alone, or by IFM and VRGN jointly following
the Effective Date (including, without limitation, as a result of Dr. Smart's
membership on the PDSC or any other activities of Dr. Smart in performing IFM's
obligations under this Agreement including carrying out the Clinical Research
Plan, and pursuant to Dr. Smart's services under the Consultancy Agreement).
Accordingly, IFM hereby agrees to assign to VRGN its entire right, title and
interest in and to any Process Development Technology and, in furtherance
thereof, IFM shall cause its employees, agents and contractors to assign to it
their respective right, title and interest in and to Process Development
Technology. All such assignments shall be irrevocable, perpetual, and without
the payment of any royalties or other consideration by VRGN now or in the
future, but the out-of-pocket costs of such assignments shall be at VRGN's
expense. IFM will disclose promptly to 


                                       31

VRGN all discoveries, developments, ideas or inventions (whether patentable or
not) constituting Process Development Technology.

     7.2 PATENT PROSECUTION, ENFORCEMENT AND DEFENSE.

     7.2.1 UNDER THE CLINICAL RESEARCH PLAN. The CRMC shall consider and
recommend to the Parties from time to time which inventions arising from the
Clinical Research Plan shall be the basis of patent applications and which shall
be maintained as trade secrets. If the Parties are unable to agree as to whether
patent protection shall be sought with respect to any invention arising under
the Clinical Research Plan, the CRMC shall make the final determination with
respect thereto. Patent applications and patents for inventions arising under
the Clinical Research Plan and which are deemed Clinical Research Plan
Information under Section 7.1.1, shall be owned by IFM pursuant to Section 7.1.1
and shall be prosecuted, maintained and enforced by IFM at its own expense and
defended against Third Party oppositions by IFM at its option and expense.

     7.2.2 NOTIFICATION REQUIREMENTS; ELECTION TO DEFEND. During the term of
this Agreement, IFM shall keep VRGN informed on a timely basis of the status of
all patent applications and patents in the Territory relating to IFM Technology
and Clinical Research Plan Information, including without limitation notifying
VRGN in writing of any and all filings of patent applications, issuances of
patents and divisions, continuations, continuations-in-part, reissues,
extensions, renewals, supplementary protection certificates and foreign
counterparts thereof (collectively, the "Patent Rights"). Attached hereto as
Exhibit B and made a part hereof is a list of the Patent Rights as of the
Effective Date. IFM shall also keep VRGN informed on a timely basis of any Third
Party oppositions, interferences or claims of patent invalidity or
unenforceability in the Territory. VRGN shall have the right, but not the
obligation, to defend at its own expense the validity or enforceability of any
patent relating to IFM Technology or Clinical Research Plan Information in the
Territory, if IFM elects not to defend the validity or enforceability of such
patent after being called upon to do so in writing by VRGN. 

     7.2.3 INFRINGEMENT. Subject to Section 7.2.4, IFM will be solely
responsible for the enforcement of patents included in the IFM Technology and
Clinical Research Plan Information, and each Party shall promptly notify the
other Party of any alleged infringement by a Third Party of patents included in
the IFM Technology or Clinical Research Plan Information in the Territory. IFM
shall have the right but not the obligation to prosecute and/or defend, at its
own expense and using counsel of its own choice, any infringement of and/or
challenge to the patents included in the IFM Technology and Clinical Research
Plan Information. In furtherance of such right, VRGN agrees that IFM may join
VRGN as a party in any such suit brought by IFM, without 


                                       32
<PAGE>   33
expense to VRGN. Any recovery of damages or settlement or award in any such suit
shall be retained in its entirety by IFM.

     7.2.4 VRGN'S OPTION TO ENFORCE PATENTS. Unless IFM, after receipt of notice
of infringement by a Third Party of IFM Technology or Clinical Research Plan
Information, either (i) causes such infringement to terminate or (ii) initiates
legal proceedings against the infringer, VRGN, upon reasonable prior notice to
IFM, may at its option initiate legal proceedings against the infringer at
VRGN's expense. Any recovery of damages or settlement or award in any such suit
at VRGN's initiation and expense shall be retained in its entirety by VRGN. In
furtherance thereof, IFM agrees that VRGN may join IFM as a party in any such
suit brought by VRGN, without expense to IFM. Any recovery of damages or
settlement or award in any such suit shall be retained in its entirety by VRGN.

     7.2.5 COOPERATION. In any suit to enforce and/or defend patents included in
the IFM Technology, Clinical Research Plan Information or Process Development
Technology, each Party shall at the request of the other Party, cooperate in all
respects and to the extent possible, have its employees testify when requested
and make available relevant records, papers, information, samples, specimens and
the like.

                         REPRESENTATIONS AND WARRANTIES

     8.1.1 BOTH PARTIES. Each Party represents and warrants to the other that:

     (a) CORPORATE POWER. It is duly organized and validly existing under the
laws of its state of incorporation, and has full corporate power and authority
to enter into this Agreement and to carry out the provisions hereof.

     (b) DUE AUTHORIZATION. It is duly authorized to execute and deliver this
Agreement and to perform its obligations hereunder, and the person executing
this Agreement on its behalf has been duly authorized to do so by all requisite
corporate action. 

     (c) BINDING AGREEMENT. This Agreement is legally binding upon it and
enforceable in accordance with its terms. The execution, delivery and
performance of this Agreement by it does not conflict with any agreement,
instrument or understanding, oral or written, to which it is a party or by which
it may be bound, nor 


                                       33
<PAGE>   34
violate any material law or regulation of any court, governmental body or
administrative or other agency having jurisdiction over it.

     (d) GRANT OF RIGHTS; MAINTENANCE OF AGREEMENTS. It has not, and will not
during the term of this Agreement, grant any right to any Affiliate or Third
Party which would conflict with the rights granted to the other Party hereunder.
It has (or will have at the time performance is due) maintained and will
maintain and keep in full force and effect all agreements necessary to perform
its obligations hereunder. 

     (e) VALIDITY. It is aware of no action, suit or inquiry or investigation
instituted by any governmental agency which questions or threatens the validity

Parties regarding Product without IFM's prior written consent not to be
unreasonably withheld or delayed.

                                    ARTICLE 9

                          CONFIDENTIALITY; PUBLICATION

     9.1 CONFIDENTIALITY. Except to the extent expressly authorized by this
Agreement or otherwise agreed in writing by the Parties, the Parties agree that,
for the longer of: (i) the term of this Agreement and for five (5) years after
its expiration or termination, or (ii) ten (10) years after the date of initial
disclosure, the receiving Party shall keep confidential and shall not publish or
otherwise disclose and shall not use for any purpose other than as provided for
in this Agreement, any Confidential Information furnished to it by the other
Party both prior to and pursuant to this Agreement, unless the receiving Party
can demonstrate by competent written proof that such Confidential Information:

     (a) was already known to the receiving Party, other than under an
obligation of confidentiality, at the time of disclosure by the other Party;

     (b) was generally available to the public or otherwise part of the public
domain at the time of its disclosure to the receiving Party; 


                                       35
<PAGE>   36
     (c) became generally available to the public or otherwise part of the
public domain after its disclosure and other than through any act or omission of
the receiving Party in breach of this Agreement; 

     (d) was disclosed to the receiving Party, other than under an obligation of
confidentiality to a Third Party, by a Third Party who had no obligation to the
disclosing Party or any other party not to disclose such information to others;
or 

     (e) was independently discovered or developed by the receiving Party
without the use of Confidential Information belonging to the disclosing Party.
It is agreed that with respect to the Confidential Information of either Party
that was disclosed to the other Party pursuant to the Confidentiality and
Non-Use Agreement between the Parties dated October 27, 1997, the disclosure of
such Confidential Information shall be subject to and governed by this Article
9.

     9.2 AUTHORIZED DISCLOSURE. Each Party may disclose Confidential Information
belonging to the other Party to the extent such disclosure is reasonably
necessary in the following instances:

     (a) filing or prosecuting patents relating to the Clinical Candidate or

     (d) complying with applicable governmental laws or regulations;

     (e) conducting pre-clinical or human clinical trials of the Clinical
Candidate or Product; 

     (f) disclosure to Affiliates, sublicensees, employees, consultants, or
agents, each of whom prior to disclosure must be bound by similar obligations of
confidentiality and non-use at least equivalent in scope to those set forth in
this Article 9; and, 

     (g) disclosure to investment bankers;

provided, however, that no disclosure of either Party's Confidential Information
under Sections 9.2(a) through (g) shall be made without such Party's prior
written consent (not to be unreasonably withheld or delayed) and, in the event
of such permitted disclosure of a Party's Confidential Information, the other
Party shall seek and obtain confidential 


                                       36
<PAGE>   37

with respect to such Confidential Information where possible, and shall take
whatever lawful actions are necessary to avoid or minimize the extent of such
disclosure.

securities exchange; in such event, however, VRGN shall request confidential
treatment thereof to the extent available, and shall provide IFM with a copy of
any such disclosure.

     9.4 INJUNCTIVE RELIEF. Each Party agrees that damages will not be an
adequate remedy to the other Party in the event of a Party's breach of its
obligations under this Article 9. Accordingly, notwithstanding Section 12.2,
each Party agrees that the other Party (without limiting such other Party's
rights or remedies otherwise available to it) shall be entitled to obtain,
without posting a bond, specific performance and preliminary and permanent
injunction from any court of competent jurisdiction, prohibiting the continuance
or recurrence of any breach of this Article 9.

of any termination of this Agreement other than VRGN's termination of this
Agreement pursuant to Section 10.2.1, VRGN's license and right to register
Product under Section 5.1 shall not survive. Promptly after termination or

     13.2 FORCE MAJEURE. Neither Party shall be responsible to the other Party
for any failure or delay in performing any of its obligations under this
Agreement if such failure or delay is caused by any act of God, earthquake,
fire, casualty, flood, war, epidemic, riot, insurrection, strike, slow-down,
walk-out or other labor disturbance, failure of public utilities, common
carriers or suppliers, or other cause beyond the reasonable control of the Party
affected if the Party affected shall have used its reasonable good faith efforts
to avoid such occurrence. If either Party believes that the performance of any
of its obligations under this Agreement will be delayed as a result of any of
the 

                                       42
<PAGE>   43
reasons stated in this Section 13.2, such Party shall promptly notify the other
Party in writing of such delay and the cause therefor, and shall provide such
other Party with its good faith estimate of when the performance of its
obligations will recommence.

     13.3 ENTIRETY OF AGREEMENT. This Agreement and the Stock Purchase Agreement
embody the entire, final and complete agreement and understanding between the
Parties with respect to the subject matter hereof and thereof, and replace and
supersede all prior discussions and agreements between them with respect to
their subject matter, including without limitation the Confidentiality and
Non-Use Agreement between the Parties dated October 27, 1997 and the letter of
intent and term sheet between the Parties dated January 12, 1998. No
modification or waiver of any terms or conditions hereof shall be effective
unless made in writing and signed by a duly authorized officer of each Party.

     13.4 NON-WAIVER. The failure of a Party in any one or more instances to
insist upon strict performance of any of the terms and conditions of this
Agreement shall not constitute a waiver or relinquishment, to any extent, of the
right to assert or rely upon any such terms or conditions on any future
occasion. 

     13.5 DISCLAIMER OF AGENCY. Neither Party is, or will be deemed to be, the
legal representative or agent of the other Party, nor shall either Party have
the right or authority to assume, create, or incur any Third Party liability or
obligation of any kind, express or implied, against or in the name of or on
behalf of the other Party except as expressly set forth in this Agreement. 

     13.6 SEVERABILITY. If a court of competent jurisdiction declares any
provision of this Agreement invalid or unenforceable, or if any government or
other agency having jurisdiction over either IFM or VRGN deems any provision to
be contrary to any laws, then that provision shall be severed and the remainder
of the Agreement shall continue in full force and effect. To the extent
possible, the Parties shall revise such invalidated provision in a manner that
will render such provision valid without impairing the Parties' original intent.

     13.7 ASSIGNMENT. Except as otherwise provided in this Agreement, neither
Party may transfer or assign its rights or obligations under this Agreement, or
subcontract or delegate performance of its obligations hereunder, without the
prior written consent of the other Party (not to be unreasonably withheld or
delayed), except that VRGN shall have the right to transfer or assign its rights
or obligations hereunder, in whole or in part, to an Affiliate or other Third
Party that acquires or is a successor to all or substantially all of VRGN's
business to which this Agreement relates, whether by merger, acquisition,
consolidation, reorganization or otherwise, or by sale of all or 

                                       43
<PAGE>   44
substantially all of VRGN's assets to which this Agreement relates, without the
consent of IFM.. This Agreement shall inure to and be binding upon the
respective successors and assigns of the Parties. Any attempted delegation or
assignment not in accordance with this Section 13.7 shall be of no force or
effect.

     13.8 HEADINGS. The Article and Section headings contained herein are for
the purposes of convenience only and are not intended to define or limit the
contents of said Articles or Sections. 

     13.9 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be an original and all of which shall
constitute together the same document. 

     IN WITNESS WHEREOF, the Parties hereto have duly executed this Agreement
as of the date first written above.

     THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
"SECURITIES ACT"), AND MAY NOT BE SOLD, OFFERED FOR SALE, ASSIGNED, TRANSFERRED
OR OTHERWISE DISPOSED OF, UNLESS REGISTERED PURSUANT TO THE PROVISIONS OF THE
SECURITIES ACT OR AN OPINION OF COUNSEL IS OBTAINED STATING THAT SUCH
DISPOSITION IS IN COMPLIANCE WITH AN AVAILABLE EXEMPTION FROM SUCH REGISTRATION.
August 14, 1998


                                  VIRAGEN, INC.
             (INCORPORATED UNDER THE LAWS OF THE STATE OF DELAWARE)

               WARRANT FOR THE PURCHASE OF SHARES OF COMMON STOCK


NO. SU-02

     FOR VALUE RECEIVED, VIRAGEN, INC., a Delaware corporation (the
"Company"), hereby certifies that Sumitomo Bank, Limited (the "Holder"), is
entitled, subject to the provisions of this Warrant, to purchase from the
Company up to 50,000 fully paid and non-assessable shares of Common Stock at a
price of US$1.78 per share (the "Exercise Price").

     The term "Common Stock" means the Common Stock, par value $.01 per
share, of the Company as constituted on August 14, 1998 (the "Base Date"). 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 Viragen, Inc., a Delaware corporation, 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 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.

     Upon receipt by the Company of evidence satisfactory to it of the loss,
theft, destruction or mutilation of this Warrant, and (in the case of loss,
theft or destruction) of



<PAGE>   46


satisfactory indemnification, and upon surrender and cancellation of this
Warrant, if mutilated, the Company shall execute and deliver a new Warrant of
like tenor and date. Any such new Warrant executed and delivered shall
constitute an additional contractual obligation on the part of the Company,
whether or not this Warrant so lost, stolen, destroyed or mutilated shall be at
any time enforceable by anyone.

     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 set forth herein.

     1. Exercise of Warrant. Subject to the provisions herein, this Warrant and 
the right to purchase the Warrant Stock hereunder shall vest and become
exercisable on the earlier of (a) the first anniversary of the Base Date and (b)
immediately prior to the consummation of the sale of all or substantially all of
the assets of the Company, or the acquisition of the Company by another entity
or group by means of a merger, sale or exchange of shares, or other transaction
as a result of which the stockholders of the Company immediately prior to such
transaction would possess a minority of the voting power of the acquiring entity
or of the Company (if it is the surviving corporation) after the closing of such
transaction. This Warrant and all rights to purchase Warrant Stock hereunder
shall expire and be of no further force and effect on the first to occur of (i)
the termination of the Strategic Alliance Agreement between the Company and
Inflammatics, Inc., a Delaware corporation, dated August 14, 1998 (the
"Strategic Alliance Agreement") pursuant to Section 10.2.1 or 10.3.1 (where the
Company is the terminating party) thereof, (ii) the termination of the
Consultancy, Confidential Information and Inventions Agreement dated as of
August 14, 1998 by and between Dr. Nigel J. Smart and the Company (the
"Consultancy Agreement") pursuant to Sections 12(i) through 12(v) and Section
12(a) thereof, and (iii) the close of business on August 14, 2003 (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. This Warrant may be exercised only in increments of not less
than 25,000 shares of Warrant Stock by presentation and surrender of this
Warrant to the Company at its principal office, or at the office of its stock
transfer agent, if any, 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) 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 his or her duly authorized attorney.
If this Warrant should be exercised in part 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. 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.


                                       2


<PAGE>   47




     2. 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 of Common
Stock (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.

     3. 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 Company 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.

     4. 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.

     5. Anti-Dilution Provisions.

     5.1 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, subdivision or split-up thereof, or if the Company shall
declare a stock dividend or distribute 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


                                       3



<PAGE>   48


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 5.1 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.

     5.2 Adjustment for Reorganization, Consolidation, Merger, Etc. In case of 
any reorganization of the Company (or any other corporation, the securities of
which are at the time receivable on the exercise of this Warrant) after the Base
Date 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.

     5.3 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 5.4 hereof.

     5.4 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


                                       4


<PAGE>   49


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.

     6. Transfer to Comply with the Securities Act. This Warrant and any Warrant
Stock or Other Securities may not be sold, assigned, transferred, pledge,
hypothecated or otherwise disposed of except as follows: (a) 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 prospectus under the
Securities Act with respect thereto and then only against receipt of an
agreement of such person to comply with the provisions of this Section 6 with
respect to any resale or other disposition of such securities; or (b) to any
person upon delivery of a prospectus then meeting the requirements of the
Securities Act relating to such securities and the offering thereof for such
sale or disposition, and thereafter to all successive assignees.

     7. Registration Rights.

     7.1 Notice of Registration. Subject to the terms of this Warrant, in the 
event the Company decides to register with the Securities Exchange Commission
any of its Common Stock (either for its own account or the account of its
security holders), the Company will: (i) promptly give the Holder written notice
thereof (which shall include a list of the jurisdictions in which the Company
intends to attempt to qualify such securities under the applicable Blue Sky or
other state securities laws), and (ii) include in such registration (and any
related qualification under Blue Sky laws or other state securities laws), and
in any underwriting involved therein, all the Warrant Stock specified in a
written request delivered to the Company by the Holder within 15 days after
delivery of such written notice from the Company.


                                       5


<PAGE>   50




     7.2 Notice of Underwriting. If the registration of which the Company gives
notice is for a public offering involving an underwriting, the Company shall so
advise the Holder as part of the written notice given pursuant to Section 7.1.
In such event the right of the Holder to registration and the inclusion of such
Holder's Warrant Stock in such underwriting shall be conditioned upon such
underwriting to the extent provided in this Section 7.2. If the Holder proposes
to distribute Warrant Stock through such underwriting it shall (together with
the Company and the other stockholders distributing their Shares through such
underwriting) enter into an underwriting agreement with the underwriter's
representative for such offering. Holder shall have no right to participate in
the selection of the underwriters.

     7.3 Marketing Limitations. In the event the underwriter's representative 
advises the Holder seeking registration of Warrant Stock pursuant to this
Section 7.3 in writing that market factors require a limitation of the number of
shares of the Company to be underwritten, the underwriter's representative may
limit the number of shares of Warrant Stock included in such registration;
provided, however, that the Warrant Stock, together with any shares of Common
Stock deliverable upon the exercise of any warrant issued to the Holder pursuant
to the Strategic Alliance Agreement shall not constitute less than 10% of the
shares of Common Stock included in such registration.

     7.4 Withdrawal. If the Holder disapproves of the terms of any such 
underwriting, the Holder may elect to withdraw therefrom by written notice to
the Company and the underwriter delivered at least seven days prior to the
effective date of the registration statement. Any Warrant Stock excluded or
withdrawn from such underwriting shall be withdrawn from such registration.

     7.5 Expenses. The Company shall bear the expenses incurred in complying 
with this Section 7, including, without limitation, all federal and state
registration, qualification and filing fees, printing expenses, fees and
disbursements of counsel for the Company and one special counsel for the Holder
and stockholders (if different from the Company), blue sky fees and expenses,
and the expense of any special audits incident to or required by any such
registration. The Holder shall bear all underwriting discounts and selling
commissions applicable to the sale of the Warrant Stock pursuant to this
Warrant.

     7.6 Registration Procedures. The Company will keep the Holder advised as to
the initiation and completion of such registration. At its expense the Company
will furnish such number of prospectuses (including preliminary prospectuses)
and other documents as the Holder from time to time may reasonably request.

     7.7 Information Furnished by Holder. It shall be a condition precedent of 
the Company's obligations under this Section 7 that the Holder furnish to the
Company such information regarding the Holder as the Company may reasonably
request.

     7.8 Indemnification.

     7.8.1 Company's Indemnification of Holder. To the extent permitted by law, 
the Company will indemnify the Holder, each of its officers, directors and
constituent partners, legal counsel for the Holder and stockholders, and each
person controlling the Holder, with respect to which registration, qualification
or compliance of Warrant Stock has been effected pursuant to this Warrant,
against all claims, losses, damages or liabilities (or actions in respect
thereof) to the extent claims, losses, damages or liabilities arise out of or
are based upon any untrue statement (or alleged untrue statement) of a material
fact contained in any prospectus or other document (including any related
registration statement) incident to any such registration, qualification or
compliance, or are based on any omission (or alleged omission) to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, or any violation by the Company of any rule
or regulation promulgated under the Act applicable to the Company and relating
to action or inaction required of the Company in connection with any such
registration, qualification or compliance; and the Company will reimburse the
Holder, each such underwriter and each person who controls the Holder or
underwriter, for any legal and any other expenses reasonably incurred in
connection with investigation or defending any such claim, loss, damage,
liability or action if settlement is effected with the consent of the Company
(which consent shall not unreasonably be withheld); and provided, further, that
the Company will not be liable in any such case to the extent that any such
claim, loss, damage, liability or expense arises out of or is based upon any
untrue statement or omission based upon written information furnished to the
Company by the Holder or controlling person.

     7.8.2 Holder's Indemnification of Company. To the extent permitted by law, 
the Holder will, if Warrant Stock is included in the securities as to which such
registration, qualification or compliance is being effected pursuant to this
Warrant, indemnify the Company, each of its directors and officers, each legal
counsel and independent accountant of the Company, each underwriter, if any, of
the Company's securities covered by such a registration statement, each person
who controls the Company or such underwriter within the meaning of the Act, and
each other stockholder of the Company whose shares are registered, each of its
officers, directors and constituent partners and each person controlling such
other stockholder; against all claims, losses, damages and liabilities (or
actions in respect thereof) arising out of or based upon any untrue statement
(or alleged untrue statement) of a material fact contained in any such
registration statement, prospectus, offering circular or other document, or any
omission (or alleged omission) to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
any violation by the Holder of any rule or regulation promulgated under the Act
applicable to the Holder and relating to action or inaction required of the
Holder in connection with any such registration, qualifications or compliance;
and will reimburse the Company, such stockholders, such directors, officers,
partners, persons, law and accounting firms, underwriters or control


                                       7


<PAGE>   52


persons for any legal and any other expenses reasonably incurred in connection
with investigation or defending any such claim, loss, damage, liability or
action, in each case to the extent, but only to the extent, that such untrue
statement (or alleged untrue statement) or omission (or alleged omission) is
made in such registration statement, prospectus, offering circular or other
document in reliance upon and in conformity with written information furnished
to the Company by the Holder and stated to be specifically for use in connection
with the offering of securities of the Company provided, however, that the
Holder's liability under this Section 7.8.2 shall not exceed the Holder's
proceeds from the offering of securities made in connection with such
registration.

     7.8.3 Indemnification Procedure. Promptly after receipt by an indemnified 
party under this Section 7.8 of notice of the commencement of any action, such
indemnified party will, if a claim in respect thereof is to be made against an
indemnifying party under this Section 7.8, notify the indemnifying party in
writing of the commencement thereof and generally summarize such action. The
indemnifying party shall have the right to participate in and to assume the
defense of such claim; provided, however, that the indemnifying party shall be
entitled to select counsel for the defense of such claim with the approval of
any parties entitled to indemnification, which approval shall not be
unreasonably withheld, unless the Holder determines that there may be a conflict
between the position of the Company and the Holder in conducting the defense of
such action, suit or proceeding by reason of recognized claims for indemnity
under this Section 7.8, then counsel for such party shall be entitled to conduct
the defense to the extent reasonably determined by such counsel to be necessary
to protect the interest of such party at the expense of the indemnifying party.
The Company shall not be required to pay the costs of more than one counsel for
Holder and other stockholders pursuant to this paragraph. The failure to notify
an indemnifying party promptly of the commencement of any such action, if
prejudicial to the ability of the indemnifying party to defend such action,
shall relieve such indemnifying party, to the extent so prejudiced, of any
liability to the indemnified party under this Section 7.8, but the omission so
to notify the indemnifying party will not relieve such party of any liability
that such party may have to any indemnified party otherwise other than under
this Section 7.8.

     7.9 Limitation on Registration Rights. Shares included in a request for
registration under this Section 7 shall not be eligible for registration under
this Section 7 if either (i) the Warrant Stock have previously been sold to the
public, or (ii) no registration under the Act is required in connection with the
disposition of such Warrant Stock pursuant to Rule 144 under the Act.

     8. Legend. Unless the shares of Warrant Stock or Other Securities have been
registered under the Securities Act, upon exercise of any of the Warrants and
the issuance of any of the shares of Warrant Stock, all certificates
representing shares will bear on the face thereof substantially the following
legend:

        IS IN COMPLIANCE WITH AN AVAILABLE EXEMPTION FROM SUCH REGISTRATION.

     2.3 Puts of Common Shares to the Subscriber.

     2.3.1 Procedure to Exercise a Put. Subject to the Individual Put Limit, the
Maximum Offering Amount and the Cap Amount (if applicable), and the other
conditions and limitations set forth in this Agreement, at any time beginning on
the date on which the Registration Statement is declared effective by the SEC
(the "Effective Date"), the Company may, in its sole and absolute discretion,
elect to exercise one or more Puts according to the following procedure:

     (a) at least ten (10) Trading Days prior to any  intended Put Date (unless
otherwise agreed in writing by the Subscriber), the Company shall deliver
advance written notice (the "Advance Put Notice," the form of which is attached
hereto as Exhibit E, the date of such Advance Put Notice being the "Advance Put
Notice Date") to Subscriber stating the Put Date for which the Company shall,
subject to the limitations and restrictions contained herein, exercise a Put and
stating the number of shares of Common Stock for which the Company shall
exercise a Put (the "Intended Put Share Amount"). Notwithstanding the above, if
more than two (2) Calendar Months have passed since the date of the previous Put
Closing, the Company shall deliver the Advance Put Notice at least twenty (20)
Trading Days prior to any intended Put Date. In order to effect delivery of the
Advance Put Notice, the Company shall (i) send the Advance Put Notice by
facsimile on such date so that such notice is received by the Subscriber by 6:00
p.m., New York, NY time, and (ii) surrender such notice on such date to a common
courier for overnight delivery to the Subscriber (or two (2) day delivery in the
case of a Subscriber residing outside of the U.S.). Upon receipt by the
Subscriber of a facsimile copy of the Advance Put Notice, the Subscriber shall,
within two (2) Business Days, send, via facsimile, a confirmation of receipt
(the "Advance Put Notice Confirmation," the form of which is attached hereto as
Exhibit F) of the Advance Put Notice to Company specifying that the Advance Put
Notice has been received and affirming the intended Put Date and the Intended
Put Share Amount;

     (b) on the Put Date specified in the Advance Put Notice, the Company 
shall deliver written notice (the "Put Notice," the form of which is
attached hereto as Exhibit G, the date of such Put Notice being the "Put Date")
to Subscriber stating (i) the Put Date, (ii) the "Put Share Amount" as specified
in the Put Notice (such exercise a "Put"); provided, however, that the Put Share
Amount specified by the Company in the Put Notice shall be equal to the Intended
Put Share Amount (as defined in Section 2.3.3 (a)), unless the Put Share Amount
must be restricted to the Individual Put Limit pursuant to Section 2.3.3 (a)
below, and (iii) the length of the Volume Evaluation Period and the Pricing
Period, each as defined below; provided, further, that the Company shall not
send a Put Notice unless at least twenty (20) Trading Days, not including any
Trading Day for which the Registration Statement is ineffective or subject to an
Ineffective Period, have elapsed (the "Trading Cushion") since the last Put Date
for which a Put was closed. In order to effect delivery of the Put Notice, the
Company shall (i) send the Put Notice by facsimile on the Put Date so that such
notice is received by the Subscriber by 6:00 p.m., New York, NY time, and (ii)
surrender such notice on the Put Date to a common courier for overnight delivery
to the Subscriber (or two (2) day delivery in the case of a Subscriber residing
outside of the U.S.). Upon receipt by the Subscriber of a facsimile copy of the
Put Notice, the Subscriber shall, within two (2) Business Days, send, via
facsimile, a confirmation of receipt (the "Put Notice Confirmation," the form of
which is attached hereto as Exhibit H) of the Put Notice to Company specifying
that the Put Notice has been received and affirming the Put Date and the Put
Share Amount;

     For purposes hereof, the "Volume Evaluation Period" shall equal the
minimum period of consecutive Trading Days, ending on the Trading Day
immediately preceding the Put Date, for which the aggregate daily reported
trading volume in the outstanding Common Stock on the Company's Principal Market
equals or exceeds two (2) times the Put Share Amount, provided


                                       10

<PAGE>   11


that the Volume Evaluation Period shall not exceed ten (10) Trading Days. The
"Pricing Period," unless otherwise shortened or extended under the terms of this
Agreement, shall equal a period of "X" Trading Days immediately following the
applicable Put Date, where "X" equals two (2) multiplied by the number of
Trading Days in the Volume Evaluation Period; provided that if a Put
Cancellation Notice has been delivered to the Subscriber after the Put Date, the
Pricing Period for such Put shall end at 6:00 p.m., New York City time, on the
Put Cancellation Date.

     (c) the "Put Share  Price"  shall  equal the  lesser of (A) 87.5% of the 
Market Price for such Put or (B) difference of (i) the Market Price for
such Put minus (ii) $0.225; and

     (d) on or before the Put Date for such Put, the Company shall deliver the 
Required Put Documents (as defined in Section 2.3.5 below) to the
Subscriber (or to an agent of Subscriber, if Subscriber so directs). Unless
otherwise specified by the Subscriber, the Put Shares of Common Stock shall be
transmitted electronically pursuant to such electronic delivery system as the
Subscriber shall request; otherwise delivery shall be by physical certificates.
If the Company has not delivered all of the Required Put Documents to the
Subscriber on or before the Put Date, the Subscriber, at its option, may cancel
the Put or may agree to extend the date that the Required Put Documents are
required to be delivered by five (5) Business Days (the "Extended Delivery
Date"), in which case the Pricing Period is extended by five (5) Trading Days.
If the Company has not delivered all of the Required Put Documents to the
Subscriber on or before the Extended Delivery Date (if applicable), the Put is
automatically canceled (an "Impermissible Put Cancellation") and, unless the Put
was otherwise canceled in accordance with the terms of Section 2.3.13, the
Company shall pay the Subscriber $15,000 for its reasonable due diligence
expenses incurred in preparation for the canceled put and the Company may
deliver an Advance Put Notice for the subsequent Put no sooner than ten (10)
Business Days after the date that such Put was canceled.

     2.3.2 Termination of Right to Put. The Company's right to require the
Subscriber to purchase any subsequent Put Shares shall terminate permanently (an
"Automatic Equity Line Termination"), unless waived in writing by the
Subscriber, upon the occurrence of any of the following:

     (a) the Company shall not exercise a Put or any Put thereafter if, at 
any time, either the Company or any director or executive officer of the
Company has engaged in a transaction or conduct that gives rise to (i) a
Securities Exchange Commission enforcement action, or (ii) a civil judgment or
criminal conviction for fraud or misrepresentation, or for any other offense
that, if prosecuted criminally, would constitute a felony under applicable law;

     (b) the Company shall not exercise a Put or any Put thereafter, on any 
date after (i) any Ineffective Period or Delisting Event, both as defined in the
Registration Rights Agreement, that lasts for four (4) consecutive months, or
(ii) after a cumulative time period including both Ineffective Periods and
Delisting Events that last for an aggregate of four (4) months;

     (c) the Company shall not exercise a Put or any Put thereafter if at any 
time the Company has filed for and/or is subject to any bankruptcy, insolvency,
reorganization or liquidation proceedings or other proceedings for relief under
any bankruptcy law or any law for the relief of debtors instituted by or against
the Company or any subsidiary of the Company; and



                                       11
<PAGE>   12


     (d) the  Company shall not exercise a Put after the sooner of (i) the 
date that is three (3) years after the date of this Agreement, or (ii) the Put
Closing Date on which the aggregate of the Put Dollar Amount for all Puts equal
the Maximum Offering Amount.

     2.3.3 Put Limitations. The Company's right to exercise a Put shall be 
limited as follows, unless waived in writing by the Subscriber:

     (a) the Company shall not exercise any Put where the aggregate Put Share 
Amount with respect to all Subscribers would exceed the Individual Put Limit in
effect on the Put Date. The "Individual Put Limit" shall equal one half of the
aggregate daily reported trading volume in the outstanding Common Stock reported
on the Company's Principal Market in a maximum Volume Evaluation Period of ten
(10) Trading Days, ending on the Trading Day immediately preceding the Put Date;

     (b) notwithstanding the amount of any Put, the Subscriber shall not be 
obligated to purchase any additional Put Shares once the aggregate Put Dollar
Amount paid by Subscriber equals the Maximum Offering Amount;

     (c) the Subscriber shall not be obligated to acquire and pay for the 
Put Shares with respect to any Put for which the Company has announced a
subdivision or combination, including a reverse split, of its Common Stock or
has subdivided or combined its Common Stock during the Extended Put Period;

     (d) the Subscriber shall not be obligated to acquire and pay for the 
Put Shares with respect to any Put for which the Company has paid a dividend of
its Common Stock or has made any other distribution of its Common Stock during
the Extended Put Period;

     (e) the Subscriber shall not be obligated to acquire and pay for the 
Put Shares with respect to any Put for which the Company has made, during the
Extended Put Period, a distribution of all or any portion of its assets or
evidences of indebtedness to the holders of its Common Stock;

     (f) the Subscriber shall not be obligated to acquire and pay for the 
Put Shares with respect to any Put for which a Major Transaction has occurred
during the Extended Put Period;

     2.3.4 Conditions Precedent to the Right of the Company to Deliver an 
Advance Put Notice or a Put Notice and the Obligation of the Subscriber to
Purchase Put Shares. The right of the Company to deliver an Advance Put Notice

                           listed, and to the Company's knowledge there is no
                           notice of any suspension or delisting with respect to
                           the trading of the shares of Common Stock on such
                           market or exchange;

                  (b)      the Company shall have satisfied any and all
                           obligations pursuant to the Registration Rights
                           Agreement, including, but not limited to, the filing
                           of the Registration Statement with the SEC with
                           respect to the resale of all Registrable Securities

<PAGE>   13


                      shall have been declared effective by the SEC for the
                      resale of all Registrable Securities and the Company shall
                      have satisfied and shall be in compliance with any and all
                      obligations pursuant to the Subscription Agreement and the
                      Warrants;

             (c)      there have been no material adverse changes in the
                      Company's business prospects or financial condition
                      (defined below in Section 5.2), including but not
                      limited to incurring material liabilities, except as
                      disclosed in the SEC documents filed by the Company
                      since the date of this Agreement;

             (d)      the representations and warranties of the Company are
                      true and correct in all material respects as if made
                      on such date and the conditions to Subscriber's
                      obligations set forth in this Section 2.3.4 are
                      satisfied as of such Closing, and the Company shall

                      Company, to such effect to the Subscriber;

             (e)      the Company shall have reserved for issuance a
                      sufficient number of Common Shares for the purpose of
                      enabling the Company to satisfy any obligation to
                      issue Common Shares pursuant to any Put and to effect
                      exercise of the Warrants;

             (f)      the Registration Statement is not subject to an
                      Ineffective Period as defined in the Registration
                      Rights Agreement, the prospectus included therein is
                      current and deliverable, and to the Company's
                      knowledge there is no notice of any investigation or
                      inquiry concerning any stop order with respect to the
                      Registration Statement;

             (g)      if the Aggregate Issued Shares after the Closing of
                      the Put would exceed the Cap Amount, the Company
                      shall have obtained the Stockholder 20% Approval as
                      specified in Section 6.12; and

                      (including but not limited to the Due Diligence
                      Review defined below) by the Subscriber or regarding

     2.3.6  Accountant's Letter and Registration Opinion.

     (a) The Company shall have caused to be delivered to the Subscriber, (i) to
the extent provided by Section 2.6, and (ii) on the date that is three (3)
Trading Days prior to each Put Date (the "Registration Opinion Deadline"), an
opinion of the Company's independent counsel, in substantially the form of
Exhibit R (the "Registration Opinion"), addressed to the Subscriber stating,
inter alia, that no facts ("Material Facts") have come to such counsel's
attention that would cause it to believe that any of the following: the
Registration Statement, any Supplemental Registration Statement, as applicable
(as each may be amended, if applicable), and any related prospectuses, contains
an untrue statement of material fact or omits a material fact required to make
the statements contained therein, not misleading or that the underlying
Prospectus (if applicable, as so amended or supplemented) contains an untrue
statement of material fact or omits a material fact required to make the
statements contained therein, in light of the circumstances in which they were
made, not misleading. If a Registration Opinion cannot be delivered by the
Company's independent counsel to the Subscriber on the Registration Opinion
Deadline due to the existence of Material Facts, the Company shall promptly
notify the Subscriber and promptly revise each of the Registration Statement and
any Supplemental Registration Statement, as applicable, and deliver such
Registration Opinion and updated prospectus as soon as possible thereafter. If
at any time after a Put Notice shall have been delivered to Subscriber but
before the Put Closing, the Company acquires knowledge of such Material Facts or
any Ineffective Period occurs, the Company shall promptly notify the Subscriber
and shall deliver a Put Cancellation Notice to the Subscriber pursuant to
Section 2.3.13 by facsimile and overnight courier by the end of that Trading
Day. The Company's independent counsel shall also deliver to the Subscriber on
the Effective Date opinions in form and substance satisfactory to the Subscriber
addressing, among other things, corporate matters and the exemption from
registration under the Securities Act of the issuance of the Common Stock by the
Company to the Subscriber under this Agreement.

     (b) (i) the Company shall engage its independent auditors to perform the
procedures in accordance with the provisions of Statement on Auditing Standards
No. 71, as amended, as agreed to by the parties hereto, and reports thereon (the
"Bring Down Cold Comfort Letters") as shall have been reasonably requested by
the Subscriber with respect to certain financial information contained in the
Registration Statement and shall have delivered to the Subscriber a report
addressed to the Subscriber, on the date that is three (3) Trading Days prior to
each Put Date.

     (ii) in the event that the Subscriber shall have requested delivery of an
"agreed upon procedures" report pursuant to Section 2.6, the Company shall
engage its independent auditors to perform certain agreed upon procedures and
report thereon as shall have been reasonably requested by the Subscriber with
respect to certain financial information of the Company and the Company shall
deliver to the Subscriber a copy of such report addressed to the Subscriber. In
the event that the report required by this Section 2.3.6(b) cannot be delivered
by the Company's independent auditors, the Company shall, if necessary, promptly
revise the Registration Statement and the Company shall not deliver a Put Notice
until such report is delivered.

     (c) in addition to the above, anytime that a Registration Opinion has not
been given to the Subscriber during the prior three (3) Calendar Months, and the
Subscriber then holds Common Stock issued pursuant to this Agreement valued at
$250,000 or more, based upon the Closing Bid Price on the day in question, the
Subscriber may require the Company to cause a Registration Opinion and a Bring
Down Cold Comfort Letter to be delivered to the Subscriber. The Company shall
provide such documents to the Subscriber within five (5) Trading Days of the
Subscriber's written request.



                                       14

     2.3.7 Put Closing Mechanics. On or before the end of the Trading Day
immediately following the Pricing Period End Date for each Put, the Company
shall deliver to the Subscriber a Pricing Confirmation Notice in the form of
Exhibit P attached hereto, setting forth the Put Share Price and the Put Dollar
Amount for such Put.

     On or before the fifth (5th) Trading Day after a Pricing Period End Date
(the "Subscriber Due Date"), the Subscriber shall deliver to the Company the Put
Dollar Amount in the manner specified in Section 8 below for such Put Shares as
specified in the Put Notice; provided, however, if the Subscriber does not
deliver to the Company the Put Dollar Amount for such Put on or before the
Subscriber Due Date, then the Subscriber shall pay to the Company, in addition
to the Put Dollar Amount, an amount (the "Late Payment Amount") at a rate of X%
per month, accruing daily, multiplied by such Put Dollar Amount, where "X"
equals one percent (1%) for the first month following the date in question, and
increases by an additional one percent (1%) for each month that passes after the
date in question, up to a maximum of five percent (5%). The closing (each a "Put
Closing") for each Put shall occur on the date that both (i) the Company has
delivered to the Subscriber all Required Put Documents, including any Additional
Shares required to be issued to the Subscriber, if applicable, and (ii) the
Subscriber has delivered to the Company such Put Dollar Amount and any Late
Payment Amount, if applicable (each a "Put Closing Date").

     2.3.8 Extension of Pricing Period Due to Press Release. In the event that
the Company makes a public announcement or press release anytime during the five
(5) Trading Days immediately preceding the Pricing Period End Date for any Put,
the Pricing Period will be extended through the fifth (5th) Trading Day after
such public announcement or Press Release.

     2.3.9 [Intentionally Left Blank].

     2.3.10 Limitation on Short Sales. The Subscriber and its Affiliates shall
not engage in short sales of the Company's Common Stock; provided, however, that
the Subscriber may enter into any short sale or other hedging or similar
arrangement it deems appropriate with respect to Put Shares after it receives an
Advance Put Notice with respect to such Put Shares so long as such sales or
arrangements do not involve more than the number of such Put Shares specified in
the Advance Put Notice (or, a good faith estimate of the number of Put Shares,
if an exact number of shares is not specified in the Advance Put Notice).

     2.3.11 Cap Amount. Unless the Company has obtained Stockholder 20% Approval
as set forth in Section 6.12 or unless otherwise permitted by Nasdaq, in no
event shall the Aggregate Issued Shares exceed the maximum number of shares of
Common Stock (the "Cap Amount") that the Company can, without stockholder
approval, so issue pursuant to Nasdaq Rule 4460(i)(1)(d)(ii) (or any other
applicable Nasdaq Rules or any successor rule) (the "Nasdaq 20% Rule"). In the
event the Company is prohibited from issuing the full amount of any Additional
Shares as a result of the operation of this Section 2.3.11, the Company shall
issue such number of shares of Common Stock as are available without exceeding
the Cap Amount (the "Cap Limit Shares") to the Subscriber as partial
consideration for its obligation to issue the Additional Shares and shall pay
the Subscriber the refund amount as specified in Section 2.3.12 below.

     2.3.12 Refund due to Cap Amount. In the event the Company is prohibited
from issuing the full amount of the Additional Shares as a result of the
operation of Section 2.3.11, the Company shall refund to the Subscriber a dollar
amount (the "Reset Cap Refund Amount") equal to the product of (a) the
difference of (i) the number of Additional Shares required to be issued by the
Company, minus (ii) the number of the Cap Limit Shares, times (b) the applicable
Put Reset Price. On or before the third (3rd) Business Day following the


                                       15

<PAGE>   16


date that such Additional Shares were required to be issued, the Company shall
deliver to the Subscriber Unlegended Share Certificates representing the Cap
Limit Shares registered in the name of Subscriber or its nominee (as instructed
by Subscriber) and free of restrictive legends and the Reset Cap Refund Amount.

     2.3.13 Put Cancellation at Company's Option.

     (a) Mechanics of Put Cancellation. Subject to the limitations below, at any
time from the Advance Put Notice Date through the last day of the Pricing
Period, the Company may cancel a Put (a "Put Cancellation"), in whole or in
part, by delivering written notice to the Subscriber (the "Put Cancellation
Notice"), attached as Exhibit Q, by facsimile and overnight courier. The "Put
Cancellation Date" shall be the date that the Put Cancellation Notice is first
received by the Subscriber, if such notice is received by the Subscriber by 6:00
p.m., New York, NY time, and shall be the following date, if such notice is
received by the Subscriber after 6:00 p.m., New York, NY time.

     (b) Limitations on Put Cancellation. The Company may not deliver a Put
Cancellation Notice unless (i) the Company discovers the existence of Material
Facts or any Ineffective Period occurs after a Put Date but before the Put
Closing (in which case Put Cancellation is mandatory), or (ii) the Closing Bid
Price on the Put Cancellation Date is less than eighty percent (80%) of the
Closing Bid Price on the applicable Advance Put Notice Date. Notwithstanding any
Put Cancellation Notice, the Put shall remain effective with respect to the
number of shares of Common Stock sold by the Subscriber from the Advance Put
Notice Date through the close of trading on the Put Cancellation Date and the
Pricing Period shall end on the Put Cancellation Date. The Company shall be
obligated, upon canceling any Put, to issue to the Subscriber Unlegended Share
Certificates representing a number of shares of Common Stock equal to the number
of shares of Common Stock sold, if any, by the Subscriber from the Advance Put
Notice Date through the close of trading on the Put Cancellation Date.

     (c) Put Cancellation Notice Confirmation. Upon receipt by the Subscriber of
a facsimile copy of the Put Cancellation Notice, the Subscriber shall promptly
send, via facsimile, a confirmation of receipt (the "Put Cancellation Notice
Confirmation") of the Put Cancellation Notice to Company specifying that the Put
Cancellation Notice has been received and affirming the Put Cancellation Date
and the number of shares of Common Stock that have been sold by the Subscriber
from the Advance Put Notice Date through the close of trading on the Put
Cancellation Date.

     2.3.14 Private Equity Line Cancellation. The Company may terminate (a
"Company Equity Line Termination") its right to initiate future Puts by
providing written notice ("Equity Line Termination Notice") to the Subscriber,
by facsimile and overnight courier, at any time, provided that such termination
shall have no effect on the parties' other rights and obligations under this
Agreement, the Registration Rights Agreement or the Warrants. Notwithstanding
the above, any cancellation occurring during an Extended Put Period is governed
by Section 2.3.13.

     2.4 Warrants.

     2.4.1 [Intentionally Omitted].

     2.4.2 Purchase Warrants. On each Six Month Anniversary of the Subscription
Date, the Company shall issue to the Subscriber a warrant ("Purchase Warrant")
to purchase a number of shares of Common Stock equal to 10% of the number of Put
Shares issued to Subscriber during the preceding six (6) Calendar Months. Each
Purchase Warrant shall be exerciseable at a price (the "Purchase Warrant
Exercise Price") which shall equal 108% of the


                                       16

<PAGE>   17


lowest Closing Bid Price for the ten (10) trading days immediately preceding the
applicable Six Month Anniversary. Each Purchase Warrant shall be immediately
exercisable at the Purchase Warrant Exercise Price, and shall have a term
beginning on the date of issuance and ending on date that is five (5) years
thereafter. The Warrant Shares shall be registered for resale pursuant to the
Registration Rights Agreement. Concurrently with the issuance and delivery of
the Purchase Warrant to the Subscriber, the Company shall deliver to the
Subscriber a Purchase Warrant Opinion of Counsel (signed by the Company's
independent counsel).

     2.5 Subscriber's Right to Defer Receipt. If at any time the Subscriber
would have the right to receive shares of Common Stock from the Company,
including, without limitation, by reason of Section 2.3 (Put) and/or the right
to receive a shares of Common Stock upon exercise of a Warrant or Warrants by
reason of Section 2.4 hereof, and as a result of receiving such additional
shares of Common Stock or such Warrants the Subscriber would be deemed to be,
after taking into account Common Shares previously acquired from the Company,
Warrant Shares deemed to be beneficially owned pursuant to ownership of the
Warrants, and any other shares of Common Stock of the Company deemed to be
beneficially owned by the Subscriber, the beneficial owner (within the meaning
of Section 13(d) of the Exchange Act) of 9.9% of the Common Stock of the
Company, the Subscriber may elect to defer receipt of all or any portion of such
Common Shares from the Company and/or defer receipt of all or any portion of
such Warrant or Warrants, by sending a notice to the Company of such election.
Such election shall not affect the Subscriber's obligation to pay for Put
Shares, as if such election had not been made, nor shall it affect (other than
by way of deferral, as set forth herein) the Subscriber's absolute and
unconditional right to receive the shares of Common Stock and/or Warrants to
which it was otherwise entitled. In the event the Subscriber makes such
election, (i) it may waive such election, in whole or in part, at any time
effective on sixty one (61) days' prior notice to the Company and (ii) may waive
it effective immediately upon notice to the Company in the event of the
announcement by the Company or any third party of a Major Transaction. The
Company shall deliver the shares and/or Warrants to which the Subscriber is
entitled on the effective date of the waiver in the case of clause (i) above,
and within three (3) Trading Days of the date of the waiver notice in the case
of a waiver pursuant to clause (ii) above.

     2.6 Due Diligence Review. The Company shall make available for inspection
and review by the Subscriber (the "Due Diligence Review"), advisors to and
representatives of the Subscriber (who may or may not be affiliated with the
Subscriber and who are reasonably acceptable to the Company), any underwriter
participating in any disposition of Common Stock on behalf of the Subscriber
pursuant to the Registration Statement, any Supplemental Registration Statement,
or amendments or supplements thereto or any blue sky, NASD or other filing, all
financial and other records, all SEC Documents and other filings with the SEC,
and all other corporate documents and properties of the Company as may be
reasonably necessary for the purpose of such review, and cause the Company's
officers, directors and employees to supply all such information reasonably
requested by the Subscriber or any such representative, advisor or underwriter
in connection with such Registration Statement (including, without limitation,
in response to all questions and other inquiries reasonably made or submitted by
any of them), prior to and from time to time after the filing and effectiveness
of the Registration Statement for the sole purpose of enabling the Subscriber
and such representatives, advisors and underwriters and their respective
accountants and attorneys to conduct initial and ongoing due diligence with
respect to the Company and the accuracy of the Registration Statement.

     2.6.1 Treatment of Nonpublic Information. The Company shall not disclose
nonpublic information to the Subscriber, advisors to or representatives of the
Subscriber unless prior to disclosure of such information the Company identifies
such information as being nonpublic information and provides the Subscriber,
such advisors and representatives with the opportunity to accept or refuse to
accept such nonpublic information for review. The Company may, as a condition to
disclosing any nonpublic information hereunder, require the Subscriber's



                                       17
<PAGE>   18


advisors and representatives to enter into a confidentiality agreement
(including an agreement with such advisors and representatives prohibiting them
from trading in Common Stock during such period of time as they are in
possession of nonpublic information) in form reasonably satisfactory to the
Company and the Subscriber.

        Nothing herein shall require the Company to disclose nonpublic
information to the Subscriber or its advisors or representatives, and the
Company represents that it does not disseminate nonpublic information to any
investors who purchase stock in the Company in a public offering, to money
managers or to securities analysts, provided, however, that notwithstanding
anything herein to the contrary, the Company will, as hereinabove provided,
immediately notify the advisors and representatives of the Subscriber and, if
any, underwriters, of any event or the existence of any circumstance (without
any obligation to disclose the specific event or circumstance) of which it
becomes aware, constituting nonpublic information (whether or not requested of
the Company specifically or generally during the course of due diligence by and
such persons or entities), which, if not disclosed in the Prospectus included in
the Registration Statement, would cause such Prospectus to include a material
misstatement or to omit a material fact required to be stated therein in order
to make the statements therein, in light of the circumstances in which they were
made, not misleading. Nothing contained in this Section 2.6 shall be construed
to mean that such persons or entities other than the Subscriber (without the
written consent of the Subscriber prior to disclosure of such information) may
not obtain nonpublic information in the course of conducting due diligence in
accordance with the terms of this Agreement; provided, however, that in no event
shall the Subscriber's advisors or representatives disclose to the Subscriber
the nature of the specific event or circumstances constituting any nonpublic
information discovered by such advisors or representatives in the course of
their due diligence without the written consent of the Subscriber prior to
disclosure of such information.

     2.6.2 Disclosure of Misstatements and Omissions. The Subscriber's advisors
or representatives shall make complete disclosure to the Subscriber's counsel of
all events or circumstances constituting nonpublic information discovered by
such advisors or representatives in the course of their due diligence upon which
such advisors or representatives form the opinion that the Registration
Statement contains an untrue statement of a material fact or omits a material
fact required to be stated in the Registration Statement or necessary to make
the statements contained therein, in the light of the circumstances in which
they were made, not misleading. Upon receipt of such disclosure, the
Subscriber's counsel shall consult with the Company's independent counsel in
order to address the concern raised as to the existence of a material
misstatement or omission and to discuss appropriate disclosure with respect
thereto; provided, however, that such consultation shall not constitute the
advice of the Company's independent counsel to the Subscriber as to the accuracy
of the Registration Statement and related Prospectus.

     2.6.3 Procedure if Material Facts are Reasonably Believed to be Untrue or
are Omitted. In the event after such consultation the Subscriber's counsel
reasonably believes that the Registration Statement contains an untrue statement
or a material fact or omits a material fact required to be stated in the
Registration Statement or necessary to make the statements contained therein, in
light of the circumstances in which they were made, not misleading,

     (a) the Company shall file with the SEC an amendment to the Registration
Statement responsive to such alleged untrue statement or omission and provide
the Subscriber, as promptly as practicable, with copies of the Registration
Statement and related Prospectus, as so amended,


                                       18
<PAGE>   19


     (b) if the Company disputes the existence of any such material misstatement
or omission, (i) the Company's independent counsel shall provide the
Subscriber's counsel with a Registration Opinion and (ii) in the event the
dispute relates to the adequacy of financial disclosure and the Subscriber shall
reasonably request, the Company's independent auditors shall provide to the
Company a letter outlining the performance of such "agreed upon procedures" as
shall be reasonably requested by the Subscriber and the Company shall provide
the Subscriber with a copy of such letter, or

     (c) if the Company disputes the existence of any such material misstatement
or omission, and the dispute relates to the timing of disclosure of a material
event and the Company's independent counsel is unable to provide the opinion
referenced in clause (b)(i) above to the Subscriber, then this Agreement shall
be suspended for a period of up to thirty (30) days, at the end of which, if the
dispute still exists between the Company's independent counsel and the
Subscriber's counsel, the Company shall either (i) amend the Registration
Statement as provided above, (ii) provide to the Subscriber the Company's
independent counsel opinion and a copy of the letter of the Company's
independent auditors referenced above, or (iii) the obligation of the Subscriber
to purchase shares of Common Stock pursuant to this Agreement shall terminate.

the meaning of Section 15 of the Act for any tax or legal advice (other than

directors; and (d) is not relying on any oral representation of the Company or

Subscriber is able to fend for Subscriber's self in the transaction contemplated
by this Agreement, that Subscriber has the ability to bear the economic risk of
Subscriber's investment pursuant to this Agreement and that Subscriber is an
"Accredited Investor" by virtue of the fact that Subscriber meets the investor
qualification standards set forth in Section 3.1 above. Subscriber has not been
organized for the purpose of investing in securities of the Company, although
such investment is consistent with Subscriber's purposes.

     3.3 Exempt Offering Under Regulation D.

     3.3.1 [Intentionally Left Blank].

     3.3.2 No General Solicitation. The Private Equity Line was not offered to
Subscriber through, and Subscriber is not aware of, any form of general

(ii) any seminar or meeting whose attendees have been invited by any general
solicitation or general advertising.

     3.3.3 Restricted Securities. Subscriber understands that the Private Equity
Line is, the Common Stock issued at each Put Closing will be, and the Warrant
Shares will be, characterized as "restricted securities" under the federal
securities laws inasmuch as they are being acquired from the Company in a
transaction exempt from the registration requirements of the federal securities
laws and that under such laws and applicable regulations such securities may not
be transferred or resold without registration under the Act or pursuant to an
exemption therefrom. In this connection, Subscriber represents that Subscriber
is familiar with Rule 144 under the Act, as presently in effect, and understands
the resale limitations imposed thereby and by the Act.

such pledge does not require registration under the Act or unless an exemption

realized upon, any transfer to the pledgee shall comply with the requirements
set forth herein), or to otherwise dispose of all or any portion of the
Securities unless and until:

     (a) There is then in effect a registration statement under the Act and any
applicable state securities laws covering such proposed disposition and such
disposition is made in accordance with such registration statement; or

     (b) (i) Subscriber shall have notified the Company of the proposed
disposition and shall have furnished the Company with a statement of the
circumstances surrounding the proposed disposition to the extent relevant for
determination of the availability of an exemption from registration, and (ii) if
reasonably requested by the Company, Subscriber shall have furnished the Company
with an opinion of counsel, reasonably satisfactory to the Company, that such
disposition will not require registration of the Securities under the Act or
state securities laws. It is agreed that the Company will not require the
Subscriber to provide opinions of counsel for transactions made pursuant to Rule
144 provided that Subscriber and Subscriber's broker, if necessary, provide the
Company with the necessary representations for counsel to the Company to issue
an opinion with respect to such transaction.

Delaware USA and has all requisite corporate power and authority to carry on its
business as now conducted and as proposed to be conducted. The Company is duly
qualified to transact business and is in good standing in each jurisdiction in

contemplated investigation or administrative or legal proceeding (a
"Proceeding") by the Internal Revenue Service, the taxing authorities of any
state or local jurisdiction, or the Securities and Exchange Commission ("SEC"),
The National Association of Securities Dealer, Inc., The Nasdaq Stock Market,
Inc. or any state securities commission, or any other governmental entity, which

ordinary course of business and normal year-end adjustments that are not, in the
aggregate, materially adverse to the Company. Except for continuing losses,
there have been no material adverse changes to the Company's business, financial
condition, or prospects since the date of such Disclosure Documents. The
financial statements as contained in the 10-K and 10-Q have been prepared in
accordance with generally accepted accounting principles, consistently applied
(except as otherwise permitted by Regulation S-X of the Exchange Act), and
fairly present the financial condition of the Company as of the dates of the
balance sheets included therein and the consolidated results of its operations
and cash flows for the periods then ended. Without limiting the foregoing, there
are no material liabilities, contingent or actual, that are not disclosed in the
Disclosure Documents (other than liabilities incurred by the Company in the
ordinary course of its business, consistent with its past practice, after the
period covered by the Disclosure Documents). The Company has paid all material
taxes, which are due, except for taxes, which it reasonably disputes. There is
no material claim, litigation, or administrative proceeding pending, or, to the
best of the Company's knowledge, threatened against the Company, except as

but which has not been so publicly announced or disclosed.

deliver and perform each agreement referenced in the previous sentence.

writ, decree, order, statute, rule or governmental regulation applicable to the
Company, which would have a material adverse effect on the Company's business or
prospects, or on the performance of its obligations under this Agreement or the
Registration Rights Agreement. The execution, delivery and performance of this
Agreement and the other agreements entered into in conjunction with the Offering
and the consummation of the transactions contemplated hereby and thereby will
not (a) result in any such violation or be in conflict with or constitute, with
or without the passage of time and giving of notice, either a default under any
such provision, instrument or contract or an event which results in the creation
of any lien, charge or encumbrance upon any assets of the Company, which would
have a material adverse effect on the Company's business or prospects, or on the
performance of its obligations under this Agreement, the Registration Rights
Agreement, (b) violate the Company's Certificate of Incorporation or By-Laws or

     6.9 Removal of Legend. If the certificates representing any Securities are
issued with a restrictive Legend in accordance with the terms of this Agreement,
the Legend shall be removed and the Company shall issue a certificate without
such Legend to the holder of any Security upon which it is stamped, and a
certificate for a security shall be originally issued without the Legend, if (a)
the sale of such Security is registered under the Act, or (b) such holder
provides the Company with an opinion of counsel, in form, substance and scope
customary for opinions of counsel in comparable transactions (the reasonable
cost of which shall be borne by the Company), to the effect that a public sale
or transfer of such Security may be made without registration under the Act, or
(c) such holder provides the Company with reasonable assurances that such
Security can be sold pursuant to Rule 144. Each Subscriber agrees to sell all
Securities, including those represented by a certificate(s) from which the
Legend has been removed, or which were originally issued without the Legend,
pursuant to an effective registration statement and to deliver a prospectus in
connection with such sale or in compliance with an exemption from the
registration requirements of the Act.

     6.10 Listing. Subject to the remainder of this Section 6.10, the Company
shall ensure that its shares of Common Stock (including all Warrant Shares) are
listed and available for trading on the Nasdaq National Market ("NMS").
Thereafter, the Company shall (i) use its best efforts to continue the listing
and trading of its Common Stock on the NMS, or on the New York Stock Exchange
("NYSE") or any other national exchange or over-the-counter market system; and
(ii) comply in all material respects with the Company's reporting, filing and
other obligations under the By-Laws or rules of the National Association of
Securities Dealers ("NASD") and such exchanges, as applicable.

     6.11 The Company's Instructions to Transfer Agent. The Company will
instruct the Transfer Agent of the Common Stock to issue certificates,
registered in the name of each Subscriber or its nominee, for the Put Shares,
Additional Shares and Warrant Shares in such amounts as specified from time to
time by the Company upon any exercise by the Company of a Put and/or exercise of
the Warrants by the holder thereof. Such certificates shall not bear a Legend
unless issuance with a Legend is permitted by the terms of this Agreement and
Legend removal is not permitted by Section 6.9 hereof and the Company shall
cause the Transfer Agent to issue such certificates without a Legend. Nothing in
this Section shall affect in any way each Subscriber's obligations and agreement
set forth in Sections 3.3.3 or 3.3.4 hereof to resell the Securities pursuant to
an effective registration statement and to deliver a prospectus in connection
with such sale or in compliance with an exemption from the registration
requirements


                                       29

<PAGE>   30


of applicable securities laws. If (a) a Subscriber provides the Company with an
opinion of counsel, which opinion of counsel shall be in form, substance and
scope customary for opinions of counsel in comparable transactions, to the
effect that the Securities to be sold or transferred may be sold or transferred
pursuant to an exemption from registration or (b) a Subscriber transfers
Securities to an affiliate which is an accredited investor pursuant to Rule 144,
the Company shall permit the transfer, and, in the case of Put Shares and
Warrant Shares, promptly instruct its transfer agent to issue one or more
certificates in such name and in such denomination as specified by such
Subscriber. The Company acknowledges that a breach by it of its obligations
hereunder will cause irreparable harm to a Subscriber by vitiating the intent
and purpose of the transaction contemplated hereby. Accordingly, the Company
acknowledges that the remedy at law for a breach of its obligations under this
Section 6.11 will be inadequate and agrees, in the event of a breach or
threatened breach by the Company of the provisions of this Section 6.11, that a
Subscriber shall be entitled, in addition to all other available remedies, to an
injunction restraining any breach and requiring immediate issuance and transfer,
without the necessity of showing economic loss and without any bond or other
security being required.

     6.12 Stockholder 20% Approval. Prior to the closing of any Put that would
cause the Aggregate Issued Shares to exceed the Cap amount, the Company shall
obtain approval of its stockholders to authorize (i) the issuance of the full
number of shares of Common Stock which would be issuable pursuant to this
Agreement but for the Cap Amount and eliminate any prohibitions under applicable
law or the rules or regulations of any stock exchange, interdealer quotation
system or other self-regulatory organization with jurisdiction over the Company
or any of its securities with respect to the Company's ability to issue shares
of Common Stock in excess of the Cap Amount (such approvals being the
"Stockholder 20% Approval").

     6.13 Press Release. The Company agrees that the Subscriber shall have the
right to review and comment upon any press release issued by the Company in
connection with the Offering which approval shall not be unreasonably withheld
by Subscriber.

becomes or is declared by a court of competent jurisdiction to be illegal,
unenforceable or void, or is altered by a term required by the Securities
Exchange Commission to be included in the Registration Statement, this Agreement
shall continue in full force and effect without said provision; provided that if
the removal of such provision materially changes the economic benefit of this
Agreement to the Subscriber, the Subscriber, at its option, may terminate this

implied, is intended to confer upon any party other than the parties hereto or
their respective successors and assigns any rights, remedies, obligations, or
liabilities under or by reason of this Agreement, except as expressly provided
in this Agreement. Subscriber may assign Subscriber's rights hereunder, in
connection with any private sale of the Common Stock of such Subscriber, so long
as, as a condition precedent to such transfer, the transferee executes an
acknowledgment agreeing to be bound by the applicable provisions of this


                                       30

<PAGE>   31


Agreement in a form acceptable to the Company and provides an original copy of
such acknowledgment to the Company.

parties actually executing such counterparts, and all of which together shall
constitute one (1) instrument.

     7.4 Titles and Subtitles; Gender. The titles and subtitles used in this
Agreement are used for convenience only and are not to be considered in

courier, addressed to the parties at the addresses and/or facsimile telephone
number of the parties set forth at the end of this Agreement or such other

and facsimile telephone numbers of the Subscriber set forth at the end of this
Agreement or such other address and/or facsimile telephone number as Subscriber
may request in writing.

     7.6 Expenses. Except as set forth in the Registration Rights Agreement,

performance of this Agreement.

     7.7 Entire Agreement; Written Amendments Required. This Agreement,
including the Exhibits attached hereto, the Common Stock certificates, the
Warrants, the Registration Rights Agreement, and the other documents delivered
pursuant hereto constitute the full and entire understanding and agreement
between the parties with regard to the subjects hereof and thereof, and no party
shall be liable or bound to any other party in any manner by any warranties,
representations or covenants except as specifically set forth herein or therein.
Except as expressly provided herein, neither this Agreement nor any term hereof
may be amended, waived, discharged or terminated other than by a written
instrument signed by the party against whom enforcement of any such amendment,
waiver, discharge or termination is sought.

     7.8 Arbitration. Except as otherwise provided in Section 6.11 of this
Agreement, any controversy or claim arising out of or related to the Transaction
Documents or the breach thereof, shall be settled by binding arbitration in
Wilmington, Delaware in accordance with the Expedited Procedures (Rules 53-57)
of the Commercial Arbitration Rules of the American Arbitration Association
("AAA"). A proceeding shall be commenced upon written demand by Company or any
Subscriber to the other. The arbitrator(s) shall enter a judgment by default
against any party, which fails or refuses to appear in any properly noticed
arbitration proceeding. The proceeding shall be conducted by one (1) arbitrator,
unless the amount alleged to be in dispute exceeds two hundred fifty thousand
dollars ($250,000), in which case three (3) arbitrators shall preside. The
arbitrator(s) will be chosen by the parties from a list provided by the AAA, and
if they are unable to agree within ten (10) days, the AAA shall select the
arbitrator(s). The arbitrators must be experts in securities law and financial
transactions. The arbitrators shall assess costs and expenses of the
arbitration, including all attorneys' and experts' fees, as the arbitrators
believe is appropriate in light of the merits of the parties' respective
positions in the issues in dispute. Each party submits irrevocably to the
jurisdiction of any state court sitting in Wilmington, Delaware or to the United
States District Court sitting in Delaware for purposes of enforcement of any
discovery order, judgment or award in connection with such arbitration. The


                                       31

<PAGE>   32


award of the arbitrator(s) shall be final and binding upon the parties and may
be enforced in any court having jurisdiction. The arbitration shall be held in
such place as set by the arbitrator(s) in accordance with Rule 55.

     Although the parties, as expressed above, agree that all claims, including
claims that are equitable in nature, for example specific performance, shall
initially be prosecuted in the binding arbitration procedure outlined above, if
the arbitration panel dismisses or otherwise fails to entertain any or all of
the equitable claims asserted by reason of the fact that it lacks jurisdiction,
power and/or authority to consider such claims and/or direct the remedy
requested, then, in only that event, will the parties have the right to initiate
litigation respecting such equitable claims or remedies. The forum for such
equitable relief shall be in either a state or federal court sitting in
Wilmington, Delaware. Each party waives any right to a trial by jury, assuming
such right exists in an equitable proceeding, and irrevocably submits to the
jurisdiction of said Delaware court. Delaware law shall govern both the
proceeding as well as the interpretation and construction of the Transaction
Documents and the transaction as a whole.

     8. Subscription and Wiring Instructions; Irrevocability.

     8.1 Subscription

         (a)  Wire transfer of Subscription Funds. Subscriber shall deliver

              letter to be provided by the Company, and signed by the Company
              and the Placement Agent.

         (b)  Irrevocable Subscription. Subscriber hereby acknowledges and
              agrees, subject to the provisions of any applicable laws providing
              for the refund of subscription amounts submitted by Subscriber,
              that this Agreement is irrevocable and that Subscriber is not
              entitled to cancel, terminate or revoke this Agreement or any
              other agreements executed by such Subscriber and delivered
              pursuant hereto, and that this Agreement and such other agreements
              shall survive the death or disability of such Subscriber and shall
              be binding upon and inure to the benefit of the parties and their
              heirs, executors, administrators, successors, legal
              representatives and assigns. If the Securities subscribed for are
              to be owned by more than one person, the obligations of all such
              owners under this  Agreement shall be joint and several, and the
              agreements, representations, warranties and acknowledgments
              herein contained shall be deemed to be made by and be binding upon
              each such person and his heirs, executors, administrators,
              successors, legal representatives and assigns. Notwithstanding the
              foregoing, (i) if the conditions to Closing are not satisfied or
              (ii) if the Disclosure Documents are discovered prior to Closing
              to contain statements which are materially inaccurate, or omit
              statements of material fact, Subscriber may revoke or cancel this
              Agreement.

     8.2 Acceptance of Subscription. Ownership of the number of securities

purchased hereby will pass to Subscriber upon the Warrant Closing or any Put
Closing.

     8.3 [Intentionally Omitted]

     9. Indemnification.

     In consideration of the Subscriber's execution and delivery of the
Subscription Agreement, the Registration Rights Agreement and the Warrants (the
"Transaction Documents")



                                       32

<PAGE>   33


and acquiring the Securities thereunder and in addition to all of the Company's
other obligations under the Transaction Documents, the Company shall defend,
protect, indemnify and hold harmless Subscriber and the Placement Agent and all
of their stockholders, officers, directors, employees and direct or indirect
investors and any of the foregoing person's agents, members, partners or other
representatives (including, without limitation, those retained in connection
with the transactions contemplated by this Agreement) (collectively, the
"Indemnitees") from and against any and all actions, causes of action, suits,
claims, losses, costs, penalties, fees, liabilities and damages, and expenses in
connection therewith (irrespective of whether any such Indemnitee is a party to
the action for which indemnification hereunder is sought), and including
reasonable attorney's fees and disbursements (the "Indemnified Liabilities"),
incurred by any Indemnitee as a result of, or arising out of, or relating to (a)
any misrepresentation or breach of any representation or warranty made by the
Company in the Transaction Documents or any other certificate, instrument or
documents contemplated hereby or thereby, (b) any breach of any covenant,
agreement or obligation of the Company contained in the Transaction Documents or
any other certificate, instrument or document contemplated hereby or thereby, or
(c) any cause of action, suit or claim, derivative or otherwise, by any
stockholder of the Company based on a breach or alleged breach by the Company or
any of its officers or directors of their fiduciary or other obligations to the
stockholders of the Company.

     To the extent that the foregoing undertaking by the Company may be
unenforceable for any reason, the Company shall make the maximum contribution to
the payment and satisfaction of each of the Indemnified Liabilities which it
would be required to make if such foregoing undertaking was enforceable which is
permissible under applicable law.

     Promptly after receipt by an Indemnified Party of notice of the
commencement of any action pursuant to which indemnification may be sought, such
Indemnified Party will, if a claim in respect thereof is to be made against the
other party (hereinafter "Indemnitor") under this Section 9, deliver to the
Indemnitor a written notice of the commencement thereof and the Indemnitor shall
have the right to participate in and to assume the defense thereof with counsel
reasonably selected by the Indemnitor, provided, however, that an Indemnified
Party shall have the right to retain its own counsel, with the reasonably
incurred fees and expenses of such counsel to be paid by the Indemnitor, if
representation of such Indemnified Party by the counsel retained by the
Indemnitor would be inappropriate due to actual or potential conflicts of
interest between such Indemnified Party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
Indemnitor within a reasonable time of the commencement of any such action, if

in a public transaction without volume limitations or other material
restrictions without registration under the Act, including without limitation,
pursuant to Rule 144 under the Act; and

     (b) any shares of Common Stock which have been sold in a private
transaction in which the transferor's rights under this Agreement are not

     2.2 Filing of Initial Registration Statement. The Company shall, by the
Filing Date, file a registration statement ("Registration Statement") on Form
S-3 (or other suitable form, at the Company's discretion, but subject to the
reasonable approval of Subscriber), covering the resale of a number of shares of
Common Stock as Registrable Securities equal to at least Fifteen Million
(15,000,000) shares of Common Stock and shall cover, to the extent allowed by
applicable law, such indeterminate number of additional shares of Common Stock

have the Registration Statement declared effective by the SEC (the date of such

     2.9 Supplemental Registration Statement for Additional Shares. Anytime the
Registration Statement does not cover a sufficient number of shares of Common
Stock to cover (i) all outstanding Registrable Securities plus (ii) all
Registrable Securities to be issued as Additional Shares, the Company shall
promptly prepare and file with the SEC such Supplemental Registration Statement
and the prospectus used in connection with such registration statement as may be
necessary to comply with the provisions of the Act with respect to the
disposition of all such Registrable Securities and shall use its best efforts to
cause such Supplemental Registration Statement to be declared effective as soon

                                       4


<PAGE>   48


     (i) Payments During Registration Statement Ineffective Period. In the event
that the Registration Statement or any Supplemental Registration Statement
becomes ineffective or unavailable for use for the sale or resale, as
applicable, of any or all of the Registrable Securities for any reason (or in
the event the prospectus under either of the above is not current and
deliverable) during any time period required hereunder (the "Ineffective
Period"), the Company shall pay the Holder at a rate equal to the Accrual Rate
multiplied by a principal amount equal to the number of shares of Registrable
Securities held by Holder on the first day of the Ineffective Period, multiplied
by the Pre-Ineffective Price, accruing daily until a Registration Statement
covering the resale of all such Registrable Securities becomes effective and a
prospectus thereunder becomes current and deliverable, payable in cash or Common
Stock, at the Holder's option, as set forth in Section 2.11 below (the
"Ineffective Registration Payment"). For the purposes hereof, if a Registration
Statement is effective but does not cover a sufficient number of shares of
Common Stock to effect resales of all Registrable Securities, then a Holder
shall be entitled to an Ineffective Registration Payment for the Ineffective
Period only as to the number of shares of Registrable Securities held by such
Holder that are not covered under the Registration Statement.

     (ii) Issuance of Additional Shares due to Price Drop During Registration
Statement Ineffective Period. In the event that an Ineffective Period occurs and
the lowest Closing Bid Price of the Common Stock for the ten (10) Trading Day
period beginning on the first Trading Day that the Registration Statement
becomes effective after the Ineffective Period (the "Post-Ineffective Price") is
less than the Closing Bid Price on the last Trading Day preceding such
Ineffective Period (the "Pre-Ineffective Price"), the Company shall issue to
Holder, no later than the fifteenth (15th) business day following the first
Trading Day after the end of the Ineffective Period, an additional number of
shares of Common Stock ("Additional Ineffective Period Shares") equal to (i) the
number of shares of Registrable Securities held by Holder on the first day of
the Ineffective Period multiplied by (ii) the difference of (x) the quotient
obtained when the Pre-Ineffective Price is divided by the Post-Ineffective
Price, minus (y) one (1). Any such shares of Common Stock issued to the Holder
as a result of any Ineffective Period shall also be deemed "Registrable
Securities" as defined herein.

     2.11 Payment of Ineffective Registration Payment or Delisting Payment. Any
Ineffective Registration Payment or Delisting Payment (a "Payment") shall be
payable in cash or Common Stock, at the Holder's option, as follows: If Holder
elects to be paid in cash, such Payment shall be paid to such Holder within five
(5) business days following the end of the month in which such Payment was
accrued. If Holder elects to be paid in Common Stock, the Company shall issue to
Holder, within five (5) business days following the end of the month in which
such Payment was accrued, a number of shares of Common Stock equal to the
quotient of (i) the dollar amount of such Payment, divided by (ii) the lowest
Closing Bid Price of the Common Stock for the ten (10) Trading Days immediately
preceding the last Trading Day of the month in which such payment was accrued.
Any such shares of Common Stock issued to the Holder as a result of any Payment
shall also be deemed "Registrable Securities" as defined herein.

     2.12 Failure to Maintain Listing of Common Stock. In the event that, at any
time during the term of the Subscription Agreement, the Company's Common Stock
is not listed for and actively trading on either the Nasdaq National Market,
Nasdaq Small Cap Market, or New York Stock Exchange or is suspended or delisted
with respect to the trading of the shares of Common Stock on such market or
exchange (a "Delisting Event"), the Company shall pay the Holder at a rate equal
to the Accrual Rate multiplied by a principal amount equal to the number of
shares of Registrable Securities held by Holder on the first day of the
Delisting Event, multiplied by the Pre-Delisting Event Price, accruing daily
until the Holder's shares of Common Stock become listed for and actively trading
on either the Nasdaq National Market, Nasdaq


                                       5

<PAGE>   49


Small Cap Market, or the New York Stock Exchange, payable in cash or Common
Stock, at the Holder's option, as set forth in Section 2.11 above (the
"Delisting Payment").

     In the event that a Delisting Event occurs and the lowest Closing Bid Price
of the Common Stock for the ten (10) Trading Day period beginning on the first
Trading Day that the Company's Common Stock is actively listed and trading on
either the Nasdaq National Market, the Nasdaq Small Cap Market or New York Stock
Exchange (the "Post-Delisting Event Price") is less than the Closing Bid Price
on the last Trading Day preceding such Delisting Event (the "Pre-Delisting Event
Price"), the Company shall issue to Holder, no later than the fifteenth (15th)
business day following the first Trading Day after the end of the Delisting
Event, an additional number of shares of Common Stock ("Additional Delisting
Event Shares") equal to (i) the number of shares of Registrable Securities then
held by Holder multiplied by (ii) the difference of (x) the quotient obtained
when the Pre-Delisting Event Price is divided by the Post-Delisting Event Price,
minus (y) one (1). Any such shares of Common Stock issued to the Holder as a
result of any Delisting Event shall also be deemed "Registrable Securities" as
defined herein.

     3. Obligations of the Company. Whenever required under this Agreement to
effect the registration of any Registrable Securities, the Company shall, as
expeditiously and reasonably possible:

     (a) Prepare and file with the Securities and Exchange Commission ("SEC") a
Registration Statement with respect to such Registrable Securities and use its
best efforts to cause such Registration Statement to become effective and to
remain effective until all Registrable Securities are resold pursuant to such
Registration Statement.

     (b) Prepare and file with the SEC such amendments and supplements to such
Registration Statement and the prospectus used in connection with such
Registration Statement ("Amended Registration Statement") or prepare and file
any additional registration statement ("Additional Registration Statement,"
together with the Amended Registration Statement, "Supplemental Registration
Statements") as may be necessary to comply with the provisions of the Act with
respect to the disposition of all securities covered by such Registration
Statement or such prior registration statement and to cover the resale of all
Registrable Securities.

     (c) Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as they may reasonably request in order
to facilitate the disposition of Registrable Securities owned by them.

     (d) Use its best efforts to register and qualify the securities covered by
such Registration Statement under such other securities or Blue Sky laws of the
jurisdictions in which the Holders are located and of such other jurisdictions
as shall be reasonably requested by the Holders of the Registrable Securities
covered by such Registration Statement, provided that the Company shall not be
required in connection therewith or as a condition thereto to qualify to do
business or to file a general consent to service of process in any such states
or jurisdictions.

     (e) [Intentionally Omitted].

     (f) As promptly as practicable after becoming aware of such event, notify
each Holder of Registrable Securities of the happening of any event of which the
Company has knowledge, as a result of which the prospectus included in the
Registration Statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under


                                       6

<PAGE>   50


which they were made, not misleading, use its best efforts promptly to prepare a
supplement or amendment to the Registration Statement to correct such untrue
statement or omission, and deliver a number of copies of such supplement or
amendment to each Holder as such Holder may reasonably request.

     (g) Provide Holders with notice of the date that a Registration Statement
or any Supplemental Registration Statement registering the resale of the
Registrable Securities is declared effective by the SEC, and the date or dates
when the Registration Statement is no longer effective.

     (h) Provide Holders and their representatives the opportunity and a
reasonable amount of time, based upon reasonable notice delivered by the
Company, to conduct a reasonable due diligence inquiry of Company's pertinent
financial and other records and make available its officers and directors for
questions regarding such information as it relates to information contained in
the Registration Statement.

     (i) Provide Holders and their representatives the opportunity to review the
Registration Statement and all amendments or supplements thereto prior to their
filing with the SEC by giving the Holder at least ten (10) business days advance
written prior to such filing; provided that if the Holders or their
representatives take more than ten (10) business days for such review and as a
direct result the Company cannot file the Registration Statement by the date it
is required to be filed hereunder.

     (j) Provide each Holder with prompt notice of the issuance by the SEC or
any state securities commission or agency of any stop order suspending the
effectiveness of the Registration Statement or the initiation of any proceeding
for such purpose. The Company shall use its best efforts to prevent the issuance
of any stop order, and, if any is issued to obtain the removal thereof at the
earliest possible date.

     (k) Use its best efforts to list the Registrable Securities covered by the
Registration Statement with all securities exchanges or markets on which the
Common Stock is then listed and prepare and file any required filing with the
NASD and any other exchange or market on which the Common Stock is listed.

     4. [Intentionally Omitted].

     5. [Intentionally Omitted].

     6. Dispute as to Registrable Securities. In the event the Company believes
that shares sought to be registered under Section 2 by Holders do not constitute
"Registrable Securities" by virtue of Section 2.1 of this Agreement, and the
status of those shares as Registrable Securities is disputed, the Company shall
provide, at its expense, an Opinion of Counsel, reasonably acceptable to the
Holders of the Securities at issue (and satisfactory to the Company's transfer
agent to permit the sale and transfer) that those securities may be sold
immediately, without volume limitation or other material restrictions, without
registration under the Act, by virtue of Rule 144 or similar provisions.

     7. Furnish Information. At the Company's request, each Holder shall furnish
to the Company such information regarding Holder, the Registrable Securities
held by it, and the intended method of disposition of such securities to the
extent required to effect the registration of its Registrable Securities or to
determine that registration is not required pursuant to Rule 144 or other
applicable provision of the Act. The Company shall include all information
provided by such Holder pursuant hereto in the Registration Statement,
substantially in the form supplied,


                                       7

<PAGE>   51


except to the extent such information is not permitted by law.

     8. Expenses. All expenses, other than commissions and fees and expenses of
counsel to the selling Holders, incurred in connection with registrations,
filings or qualifications pursuant hereto, including (without limitation) all
registration, filing and qualification fees, printers' and accounting fees, fees
and disbursements of counsel for the Company, shall be borne by the Company.


                                       8


<PAGE>   52


     9. Indemnification. In the event any Registrable Securities are included in
a Registration Statement under this Agreement:

     (a) To the extent permitted by law, the Company will indemnify and hold
harmless each Holder, the officers, directors, partners, legal counsel, and
accountants of each Holder, any underwriter (as defined in the Act, or as deemed
by the Securities Exchange Commission, or as indicated in a registration
statement) for such Holder and each person, if any, who controls such Holder or
underwriter within the meaning of Section 15 of the Act or the Securities
Exchange Act of 1934, as amended (the "1934 Act"), against any losses, claims,
damages, or liabilities (joint or several) to which they may become subject
under the Act, the 1934 Act or 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 or omissions: (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, or (ii)
the omission or alleged omission to state therein a material fact required to be
stated therein, or necessary to make the statements therein not misleading, and
the Company will reimburse each such Holder, officer or director, underwriter or
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this subsection 9(a) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability, or action if such settlement is effected
without the consent of the Company (which consent shall not be unreasonably
withheld), nor shall the Company be liable in any such case for any such loss,
claim, damage, liability, or action to the extent that it arises out of or is
based upon a violation which occurs in reliance upon and in conformity with
written information furnished expressly for use in connection with such
registration by any such Holder, officer, director, underwriter or controlling
person; provided however, that the above shall not relieve the Company from any
other liabilities which it might otherwise have.

     (b) Promptly after receipt by an indemnified party under this Section 9 of
notice of the commencement of any action (including any governmental action),
such indemnified party will, if a claim in respect thereof is to be made against
any indemnifying party under this Section 9, 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 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 shall have the right to retain its own
counsel, with the reasonably incurred fees and expenses of one such counsel 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 conflicting 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 materially prejudicial to its ability to
defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 9, 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 9.

     (c) In the event that the indemnity provided in paragraph (a) of this
Section 9 is unavailable to or insufficient to hold harmless an indemnified
party for any reason, the Company and each Holder agree to contribute to the
aggregate claims, losses, damages and liabilities (including legal or other
expenses reasonably incurred in connection with investigating or defending same)
(collectively "Losses") to which the Company and one or more of the Holder may
be subject in such proportion as is appropriate to reflect the relative fault of
the


                                       9

<PAGE>   53


Company and the Holders in connection with the statements or omissions which
resulted in such Losses. Relative fault shall be determined by reference to
whether any alleged untrue statement or omission relates to information provided
by the Company or by the Holders. The Company and the Holders agree that it
would not be just and equitable if contribution were determined by pro rata
allocation or any other method of allocation that does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 10(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 9, each person who controls a
Holder of Registrable Securities within the meaning of either the Securities Act
or the Exchange Act and each director, officer, partner, employee and agent of a
Holder shall have the same rights to contribution as such holder, and each
person who controls the Company within the meaning of either the Act or the
Exchange Act and each director and officer of the Company shall have the same
rights to contribution as the Company, subject in each case to the applicable
terms and conditions of this paragraph (c).

     (d) The obligations of the Company and Holders under this Section 9 shall
survive the resale, if any, of the Common Stock, the completion of any offering
of Registrable Securities in a Registration Statement under this Agreement, and
otherwise.

     10. Reports Under Securities Exchange Act of 1934. With a view to making
available to the Holders the benefits of Rule 144 promulgated under the Act and
any other rule or regulation of the SEC that may at any time permit a Holder to
sell securities of the Company to the public without registration, the Company
agrees to:

     (a) make and keep public information available, as those terms are
understood and defined in Rule 144; and

     (b) use its best efforts to file with the SEC in a timely manner all
reports and other documents required of the Company under the Act and the 1934
Act.

     11. Amendment of Registration Rights. Any provision of this Agreement may
be amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of the Company and the written consent of each Holder affected
thereby. Any amendment or waiver effected in accordance with this paragraph
shall be binding upon each Holder, each future Holder, and the Company.

     12. Notices. All notices required or permitted under this Agreement shall
be made in writing signed by the party making the same, shall specify the
section under this Agreement pursuant to which it is given, and shall be

233-1416 and (ii) the Holders at their respective last address as the party as
shown on the records of the Company. Any notice, except as otherwise provided in
this Agreement, shall be made by fax and shall be deemed given at the time of
transmission of the fax.

     13. Termination. This Agreement shall terminate on the date all Registrable
Securities cease to exist (as that term is defined in Section 2.1 hereof); but
without prejudice to (i) the parties' rights and obligations arising from
breaches of this Agreement occurring prior to such termination (ii) other
indemnification obligations under this Agreement.

     14. Assignment. No assignment, transfer or delegation, whether by operation
of law or otherwise, of any rights or obligations under this Agreement by the
Company or any Holder,


                                       10

<PAGE>   54


respectively, shall be made without the prior written consent of the majority in
interest of the Holders or the Company, respectively; provided that the rights
of a Holder may be transferred to a subsequent holder of the Holder's
Registrable Securities (provided such transferee shall provide to the Company,
together with or prior to such transferee's request to have such Registrable
Securities included in a Registration, a writing executed by such transferee
agreeing to be bound as a Holder by the terms of this Agreement), and the
Company hereby agrees to file an amended registration statement including such
transferee or a selling security holder thereunder; and provided further that
the Company may transfer its rights and obligations under this Agreement to a
purchaser of all or a substantial portion of its business if the obligations of
the Company under this Agreement are assumed in connection with such transfer,
either by merger or other operation of law (which may include without limitation
a transaction whereby the Registrable Securities are converted into securities
of the successor in interest) or by specific assumption executed by the
transferee.

     15. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware applicable to agreements made
in and wholly to be performed in that jurisdiction, except for matters arising
under the Act or the Securities Exchange Act of 1934, which matters shall be
construed and interpreted in accordance with such laws.

     16. Execution in Counterparts Permitted. This Agreement may be executed in
any number of counterparts, each of which shall be enforceable against the
parties actually executing such counterparts, and all of which together shall
constitute one (1) instrument.

     17. Specific Performance. The Holder shall be entitled to the remedy of
specific performance in the event of the Company's breach of this Agreement, the
parties agreeing that a remedy at law would be inadequate.

     18. Indemnity. Each party shall indemnify each other party against any and
all claims, damages (including reasonable attorney's fees), and expenses arising
out of the first party's breach of any of the terms of this Agreement.

     19. Entire Agreement; Written Amendments Required. This Agreement,
including the Exhibits attached hereto, the Subscription Agreements, the Common
Stock certificates, and the other documents delivered pursuant hereto constitute
the full and entire understanding and agreement between the parties with regard
to the subjects hereof and thereof, and no party shall be liable or bound to any
other party in any manner by any warranties, representations or covenants except
as specifically set forth herein or therein. Except as expressly provided
herein, neither this Agreement nor any term hereof may be amended, waived,
discharged or terminated other than by a written instrument signed by the party
against whom enforcement of any such amendment, waiver, discharge or termination
is sought.

                            PLACEMENT AGENT AGREEMENT  

     THIS AGREEMENT ("Agreement") is made as of the 22nd day of September, 1998,
by and between Viragen, Inc., a corporation organized under the laws of the
state of Delaware ("Company"), and Swartz Investments LLC, a Georgia limited
liability company, d/b/a Swartz Institutional Finance (the "Placement Agent").

                                    RECITALS:

     WHEREAS, the Company proposes to issue and sell that certain Regulation D
Private Equity Line Subscription Agreement (the "Private Equity Line Agreement")
and shares of its Common Stock issued in connection therewith, which are
accompanied by a warrant or warrants to purchase a number of shares of Common
Stock of the Company (together the "Securities") resulting in gross proceeds to
the Company of a maximum of Twenty Million Dollars ($20,000,000), excluding
Warrants, in an offering (the "Offering") not involving a public offering under
the Securities Act of 1933, as amended (the "Act"), pursuant to an exemption
from the registration requirements of the Act under Regulation D promulgated
under the Act ("Regulation D"), as described below; and

     WHEREAS, the Placement Agent has offered to assist the Company in placing
the Private Equity Line Agreement on a "best efforts" basis with respect to
sales of Securities thereafter up to the Maximum Proceeds (as defined below),
and the Company desires to secure the services of the Placement Agent on the
terms and conditions hereinafter set forth.

                                     TERMS:

     NOW, THEREFORE, in consideration of the premises and the mutual promises,
conditions and covenants herein contained, the parties hereto do hereby agree as
follows:

     1. ENGAGEMENT OF PLACEMENT AGENT. The Company on the basis of the
representations and warranties contained herein, but subject to the terms and
conditions herein set forth, hereby appoints the Placement Agent as its
exclusive placement agent for this Offering, to sell, on a "best efforts basis,"
a maximum dollar amount of Securities, excluding Warrants, resulting in gross
proceeds to the Company of Twenty Million Dollars ($20,000,000) (the "Maximum
Proceeds"). The Placement Agent, on the basis of the representations and
warranties herein contained, but subject to the terms and conditions herein set
forth, accepts such appointment and agrees to use its best efforts to find
purchasers for the Private Equity Line Agreement. This appointment shall be
irrevocable for the period commencing on the date of the executed Letter of
Agreement, and ending on the earlier of (i) the Put Closing Date on which the
aggregate of the Put Dollar Amounts for all Put Closings equal the Maximum
Offering Amount pursuant to the Private Equity Line Agreement, or (ii) September
30, 2001.

     2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. In order to induce the
Placement Agent to enter into this Agreement, the Company hereby represents and
warrants to and agrees with the Placement Agent as follows:

     2.1 Offering Documents. The Company (with the assistance of the Placement
Agent) has prepared the Private Equity Line Agreement, certain exhibits thereto,
investor Warrants and a Registration Rights Agreement, which documents have been
or will be sent to proposed investors. In addition, proposed investors have
received or will receive prior to the Private Equity Line Commitment Closing (as
defined in the Private Equity Line Agreement), copies of the Company's Annual
Report on Form 10-K for the year ended June 30, 1997 and the Company's quarterly
report on Form 10-Q for the quarter ended March 31, 1998 ("SEC Documents"). The
SEC Documents were prepared in conformity with the requirements (to the extent
applicable) of the Securities Exchange Act of 1934, as amended, (the "`34 Act")
and the rules and regulations ("Rules and Regulations") of the Commission
promulgated thereunder. As used in this Agreement, the term "Offering Documents"
refer to and mean the SEC Documents, the Private Equity Line Agreement and all
amendments, exhibits and supplements thereto, together with any other documents
which are provided to the Placement Agent by, or approved for Placement Agent's
use by, the Company for the purpose of this Offering (including, but not limited
to, the Registration Rights Agreement).

     2.2 Provision of Offering Documents. The Company shall deliver to the
Placement Agent, without charge, as many copies of the Offering Documents as the
Placement Agent may reasonably require for the purposes contemplated by this
Agreement. The Company authorizes the Placement Agent, in connection with the
Offering of the Private Equity Line Agreement, to use the Offering Documents as
from time to time amended or supplemented in connection with the offering and
sale of the Private Equity Line Agreement and in accordance with the applicable
provisions of the Act and Regulation D.

     2.3 Accuracy of Offering Documents. The Offering Documents, at the time of
delivery to Subscribers for the Securities, conformed in all material respects
with the requirements, to the extent applicable, of the `34 Act and the
applicable Rules and Regulations and did not include any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading. On any Closing Date (as hereinafter
defined), the Offering Documents will contain all statements which are required
to be stated therein in accordance with the Act and the Rules and Regulations
for the purposes of the proposed Offering, and all statements of material fact
contained in the Offering Documents will be true and correct, and the Offering
Documents will not include any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.


                                       2

<PAGE>   58


     2.4 Duty to Amend. If during such period of time as in the reasonable
opinion of the Placement Agent or its counsel an Offering Document relating to
this financing is required to be delivered under the Act, any event occurs or
any event known to the Company relating to or affecting the Company shall occur
as a result of which the Offering Documents as then amended or supplemented
would include an untrue statement of a material fact, or omit to state any
material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, or if it is necessary
at any time after the date hereof to amend or supplement the Offering Documents
to comply with the Act or the applicable Rules and Regulations, the Company
shall forthwith notify the Placement Agent thereof and shall prepare such
further amendment or supplement to the Offering Documents as may be required and
shall furnish and deliver to the Placement Agent and to others, whose names and
addresses are designated by the Placement Agent, all at the cost of the Company,
a reasonable number of copies of the amendment or supplement (or of the amended
or supplemented Offering Documents) which, as so amended or supplemented, will
not contain an untrue statement of a material fact or omit to state any material
fact necessary in order to make the Offering Documents not misleading in the
light of the circumstances when delivered to a purchaser or prospective
purchaser, and which will comply in all respects with the requirements (to the
extent applicable) of the `34 Act and the applicable Rules and Regulations.

     2.5 Corporation Condition. The Company's condition is as described in its
Offering Documents, except for continuing losses and changes in the ordinary
course of business and normal year-end adjustments that are not in the aggregate
materially adverse to the Company. The Offering Documents, taken as a whole,
present fairly the business and financial position of the Company as of any
Closing Date.

     2.6 No Material Adverse Change. Except as may be reflected in or
contemplated by the Offering Documents, subsequent to the dates as of which
information is given in the Offering Documents, and prior to any Closing Date,
taken as a whole, there has not been any material adverse change in the
condition, financial or otherwise, or in the results of operations of the
Company or in its business.

     2.7 No Defaults. Except as disclosed in the Offering Documents or in
writing to the Placement Agent, the Company is not in default in any material
respect in the performance of any obligation, agreement or condition contained
in any material debenture, note or other evidence of indebtedness or any
material indenture or loan agreement of the Company. The execution and delivery
of this Agreement, and the consummation of the transactions herein contemplated,
and compliance with the terms of this Agreement will not conflict with or result
in a breach of any of the terms, conditions or provisions of, or constitute a
default under, the Certificate of Incorporation or By-Laws of the Company (in
any respect that is material to the Company), any material note, indenture,
mortgage, deed of trust, or other agreement or instrument to which the Company
is a party or by which the Company or any property of the Company is bound, or
to the Company's knowledge, any existing law, order, rule, regulation, writ,
injunction


                                       3

<PAGE>   59


or decree of any government, governmental instrumentality, agency or body,
arbitration tribunal or court, domestic or foreign, having jurisdiction over the
Company or any property of the Company. The consent, approval, authorization or
order of any court or governmental instrumentality, agency or body is not
required for the consummation of the transactions herein contemplated except
such as may be required under the Act or under the Blue Sky or securities laws
of any state or jurisdiction.

     2.8 Incorporation and Standing. The Company is, and at any Closing Date
will be, duly formed and validly existing in good standing as a corporation
under the laws of the State of Delaware and with full power and authority
(corporate and other) to own its properties and conduct its business, present
and proposed, as described in the Offering Documents; the Company, has full
power and authority to enter into this Agreement; and the Company is duly
qualified and in good standing as a foreign entity in each jurisdiction in which
the failure to so qualify would have a material adverse effect on the Company or
its properties.

     2.9 Legality of Outstanding Securities.Prior to any Closing Date, the
outstanding securities of the Company have been duly and validly authorized and
issued, and are fully paid and non-assessable, and conform in all material
respects to the statements with regard thereto contained in the Offering
Documents.

     2.10 Legality of Securities. The Securities when sold and delivered in
accordance with the Offering Documents, and the Placement Agent Warrants (as
defined in Section 3.4 below) when issued and delivered, will constitute legal,
valid and binding obligations of the Company, enforceable in accordance with the
terms thereof, and the Securities shall be duly and validly issued and
outstanding, fully paid and nonassessable. The Common Stock into which any
Securities are exercisable and the Common Stock into which any of Placement
Agent's Warrants are exercisable, when issued upon exercise of any Securities or
upon exercise of any of Placement Agent's Warrants, as applicable, shall be duly
and validly issued and outstanding, fully paid and non-assessable.

     2.11 Litigation. Except as set forth in the Offering Documents, there is
now, and at any Closing Date there will be, no action, suit or proceeding before
any court or governmental agency, authority or body pending or, to the knowledge
of the Company, threatened, which might result in judgments against the Company
not adequately covered by insurance or which collectively might result in any
material adverse change in the condition (financial or otherwise) or business of
the Company or which would materially adversely affect the properties or assets
of the Company.

     2.12 Finders. The Company does not know of any outstanding claims for
services in the nature of a finder's fee or origination fees with respect to the
sale of the Private Equity Line Agreement hereunder for which the Placement
Agent may be responsible, and the Company will indemnify the Placement Agent
from any liability for such fees (including the payment of attorney's fees
incurred by Placement Agent due


                                       4

<PAGE>   60


to any claim by any such finder or originator) by any party who, in the
reasonable opinion of Placement Agent's counsel, has a legitimate claim for such
compensation from the Company and for which person the Placement Agent is not
legally responsible. In the event of such claim, Placement Agent shall properly
notify Company thereof and the Company may, at its option and at its sole cost
and expense, take over the defense of such a claim with counsel of its choice,
reasonably satisfactory to Placement Agent. Placement Agent shall not settle any
such claims or litigation arising hereunder without the prior written consent of
the Company, which shall not be unreasonably withheld.

     2.13 Tax Returns. The Company has filed all federal and state and local tax
returns which are required to be filed, and has paid all material taxes shown on
such returns and on all assessments received by it to the extent such taxes have
become due (except for taxes the amount of which the Company is contesting in
good faith). All taxes with respect to which the Company is obligated have been
paid, or adequate accruals have been set up to cover any such unpaid taxes.

     2.14 Authority. The execution and delivery by the Company of this Agreement
have been duly authorized by all necessary action, and this Agreement is the
valid, binding and legally enforceable obligation of the Company except as
enforcement may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium and other similar laws, by principles governing enforcement of
equitable remedies and, with respect to indemnification against liabilities
under the Act, matters of public policy.

     2.15 Actions by the Company. The Company will not take any action which
will impair the effectiveness of the transactions contemplated by this
Agreement.

     3. ISSUE, SALE AND DELIVERY OF THE SECURITIES.

     3.1 Deliveries of Securities. Certificates in such form that, subject to
applicable transfer restrictions as described in the Private Equity Line

or the Subscriber's agent as specified in the Private Equity Line Agreement,
with copies made available to the Subscriber for checking at least one (1) full

                                       5

<PAGE>   61


     3.3 Closing Date. The Private Equity Line Commitment Closing shall take
place at the offices of the Placement Agent. Any subsequent Put Closing shall
take place at the offices of the Subscriber or Subscriber's agent on each Put
Closing Date as specified in the Private Equity Line Agreement. For purposes
hereof, "Put Closing" and "Put Closing Date" shall have the meanings as set
forth in Private Equity Line Agreement. The date of the Private Equity Line
Commitment Closing and any Put Closing Date shall be referred to herein as the
"Closing Date."

     3.4 Placement Agent's Compensation. Subject to cancellation under Sections
12.2 and 12.3, the Company shall pay the Placement Agent the following, which
shall be the full amount payable to the Placement Agent for its services, as
fees and expenses, in connection with this Offering:

A cash placement fee ("Cash Placement Fee") equal to "X" percent (X%) of the
gross proceeds resulting from the sale of the securities in any Put, wherein "X"
is based on the aggregate amount of securities placed to date as follows:

                           Aggregate Amount Placed            "X"
                           -----------------------            ---
                           First $5M                           7%
                           $5M-$10M                            6%
                           $10M plus                         3.5%

On each Six Month Anniversary of the Subscription Date, if the Placement Agent
has not received at least $100,000 in Cash Placement Fees for the preceding six
(6) Calendar Months, the Company shall pay to the Placement Agent an amount
equal to (the "Semi-Annual Cash Fee Shortfall") the difference of (i) $100,000,
minus (ii) the amount of the Cash Placement Fee paid to the Placement Agent
during the preceding six (6) Calendar Months (as defined in the Private Equity
Line Agreement). In the event that the Company delivers a Termination Notice to
the Subscriber, the Company shall pay to the Placement Agent the greater of (i)
$100,000, less the fee on amounts put to the Subscriber in that six (6) month
period, or (ii) the difference of (x) $200,000, minus (y) the aggregate of the
Cash Placement Fees for all Puts to date, and the Company shall not be required
to pay the Semi-Annual Cash Fee Shortfall thereafter.

     3.5 Placement Agent's Warrants. In addition to the fees and reimbursement
of costs set forth above, within five (5) business days after each Six Month
Anniversary of the Subscription Date as specified in the Private Equity Line
Agreement, the Company shall also issue to Placement Agent or its designees the
following warrants ("Placement Agent Warrants"): (i) a warrant to purchase a
number of shares of the Company's Common Stock equal to "X" percent (X%) of the
number of shares of Put Shares of Common Stock issued to the Subscriber pursuant
to any Put as specified in the Private Equity Line Agreement during the
preceding six (6) month period, exercisable at one hundred twenty five percent
(125%) of the average Put Share Price of all such Put Shares issued during the
preceding six (6) calendar months; and (ii) a


                                       6

<PAGE>   62


warrant to purchase a number of shares of the Company's Common Stock equal to
"X" percent (X%), as specified above, of the number of shares of Common Stock
for which the Subscriber is entitled to purchase pursuant to each Purchase
Warrant issued to the Subscriber on that Six Month Anniversary Date,
exerciseable at a price which shall equal 108% of the lowest Closing Bid Price
for the ten (10) trading days immediately preceding the applicable Six Month
Anniversary.

     The term of the Placement Agent Warrants shall be five (5) years commencing
on the date of issuance thereof. The Placement Agent Warrants shall be
exercisable immediately upon issuance and shall have cashless exercise
provisions. The shares of Common Stock issuable upon exercise of the Placement
Agent Warrants shall be included in the next registration statement filed by the
Company, and shall have the rights set forth in the Registration Rights
Agreement, dated on or about September 18, 1998, by and among the Company, the

be made upon the terms and subject to the conditions set forth in the Offering
Documents. The Placement Agent shall commence making such offer as an agent for
the Company as soon as possible following delivery of the final Company approved
Offering Documents to Placement Agent (or notification by Company or its Counsel

<PAGE>   63


Agreement from, persons or entities that Placement Agent reasonably believes are
"accredited investors" as defined in Regulation D.

     5. RIGHT OF FIRST REFUSAL. The Company hereby grants Placement Agent rights
of first refusal as follows:

     5.1 The Placement Agent has the right of first refusal to act as placement
agent for any future financings of the Company, including any financings that
involve the participation of an underwriter, under which the Company issues or
sells, or agrees to issue or sell, for cash (a) any debt or equity securities
which are convertible into, exercisable or exchangeable for, or carry the right
to receive additional shares of Common Stock either (i) at any conversion,
exercise or exchange rate or other price that is based upon and/or varies with
the trading prices of or quotations for Common Stock at any time after the
initial issuance of such debt or equity security, (ii) with a fixed conversion,
exercise or exchange price, or (iii) with a fixed conversion, exercise or
exchange price that is subject to being reset at some future date at any time
after the initial issuance of such debt or equity security or upon the
occurrence of specified contingent events directly or indirectly related to the
business of the Company or the market for the Common Stock, (b) any securities
of the Company pursuant to an equity line structure or format similar in nature
to this Offering or otherwise, or (c) any Common Stock or units (i.e. Common
Stock accompanied by warrants) of the Company, excluding joint ventures,
mergers, acquisitions, or similar transactions. Notwithstanding the above, the
Placement Agent shall not be entitled to a right of first refusal under this
sub-section with respect to a VUSA Transaction (as defined in the Private Equity
Line Agreement). The duration of the Placement Agent's right of first refusal
under this Section 5.1 shall be for a period from the date of this Agreement
until the earlier of (i) the date that is three (3) years following the date of
the Private Equity Line Commitment Closing (as defined in the Private Equity
Line Agreement), or (ii) (a) in the case of a Company Equity Line Termination
(as defined in the Private Equity Line Agreement), the date that is one (1) year
after the date of such Company Equity Line Termination, or (b) in the case of an
Automatic Equity Line Termination Closing (as defined in the Subscription
Agreement) that is not waived by the Subscriber, the date that is six (6) months
after the date of such Automatic Equity Line Termination.

     5.2 In the event that the Company wishes to undertake a transaction
described in this Section 5, the Company must send Placement Agent a written
notice of the proposed transaction (whether the transaction is initiated by the
Company or is offered to the Company by a third party), in sufficient
specificity to allow the Placement Agent to understand the proposed transaction
clearly. This notice must be delivered to Placement Agent at least twenty (20)
days prior to the proposed closing of the transaction. The Placement Agent shall
have fifteen (15) days from receipt of that notice to determine whether or not
it wishes to exercise its right of first refusal with respect to that
transaction. The Placement Agent shall notify the Company in writing of its
decision to exercise or waive its right of first refusal with respect to the
transaction described in the notice. If the Placement Agent waives its right of
first refusal with respect to a


                                       8

<PAGE>   64

particular transaction, the Company may proceed with that transaction; provided,
however, that if prior to any Closing in the proposed transaction the terms of
the transaction are changed in any material way from the terms set forth in the
notice to the Placement Agent, the Placement Agent's right of first refusal
shall commence again. Placement Agent's waiver of its rights of first refusal
with respect to any specific transaction shall not act as a waiver of its rights
with respect to future transactions within the applicable time period.

     5.3 In the event that Company breaches Section 5.1 of this Agreement,
Placement Agent shall be entitled to receive compensation based upon the
aggregate purchase price of securities placed in such transaction in an amount
calculated pursuant to Section 3.4 hereof.

     6. COVENANTS OF THE COMPANY. The Company covenants and agrees with the
Placement Agent that:

     6.1 After the date hereof, the Company will not at any time, prepare and
distribute any amendment or supplement to the Offering Documents (other than the
Company's 10-Q's, 10-K's and period reports filed with the SEC), of which
amendment or supplement the Placement Agent shall not previously have been
advised and the Placement Agent and its counsel furnished with a copy within a
reasonable time period prior to the proposed adoption thereof, or to which the
Placement Agent shall have reasonably objected in writing on the ground that it
is not in compliance with the Act or the Rules and Regulations (if applicable).

     6.2 The Company will pay, whether or not the transactions contemplated
hereunder are consummated or this Agreement is prevented from becoming effective
or is terminated, all costs and expenses incident to the performance of its
obligations under this Agreement, including all expenses incident to the
authorization of the Securities and their issue and delivery to the Placement
Agent, any original issue taxes in connection therewith, all transfer taxes, if
any, incident to the initial sale of the Securities, the fees and expenses of
the Company's counsel and accountants, the cost of reproduction and furnishing
to the Placement Agent copies of the Offering Documents as herein provided;
provided, however, that the Company shall not be responsible for the direct
payment of fees and costs incurred by Placement Agent, including attorney's fees
of or any costs incurred by the Placement Agent's counsel.

     6.3 As a condition precedent to any Closing, the Company will deliver to
the Placement Agent a true and correct copy of all documents requested by
Placement Agent included in Placement Agent's due diligence request, including
but not limited to the Certificate of Incorporation of the Company, and all
amendments and certificates of designation of preferences of preferred stock,
certified by the Secretary of State of the State of Delaware.

<PAGE>   65

     6.4 Prior to any Closing Date, the Company will cooperate with the
Placement Agent in such investigation as it may make or cause to be made of all
of the properties, business and operations of the Company in connection with the
Offering of the Securities. The Company will make available to it in connection
therewith such information in its possession as the Placement Agent may
reasonably request and will make available to the Placement Agent such persons
as the Placement Agent shall deem reasonably necessary and appropriate in order
to verify or substantiate any such information so supplied.

     6.5 The Company shall be responsible for making any and all filings
required by the Blue Sky authorities of the State of Delaware and filings
required by the laws of the jurisdictions in which the Subscribers who are
accepted for purchase of Private Equity Line Agreement are located, if any.

     7. NON-CIRCUMVENTION & CONFIDENTIALITY OF PROPRIETARY PLACEMENT AGENT
INFORMATION.

     7.1. Non-Circumvention. The investors who participate in the Offering and
the other investors who are listed on the schedule attached hereto as Exhibit B
shall be considered, for purposes of this Agreement, the Placement Agent's
proprietary clients. The Company on behalf of itself, its parent or its
subsidiaries (collectively hereinafter referred to as "Company") agree not to
circumvent, directly or indirectly, Placement Agent's relationship with these
investors, their parents or any of the investors' subsidiaries or affiliates
(collectively hereinafter referred to as "Investors") and Company will not
directly or indirectly contact or negotiate with any of these Investors
regarding an investment in the Company, or any other company, and will not enter
into any agreement or transaction with Investors, or disclose the names of
Investors, except as such disclosure may be required by any law, rule,
regulation, regulatory body, court or administrative agency, for a period of
time beginning on the date hereof and ending on the date that is three (3) years
after the date of the Private Equity Line Commitment Closing without the prior
written approval of Placement Agent; provided, however, that notwithstanding the
above, nothing contained in this Agreement shall prevent Company from, directly
or indirectly, contacting or negotiating with the Investors in satisfaction of
Company's obligations under the Private Equity Line Agreements entered into in
connection herewith. In the event that the Company, with Swartz's advance
written permission, accepts an investment (a "Subsequent Investment") from an
Investor or Investors (other than in a public offering) in a placement being
arranged without an agent or through an agent other than the Placement Agent,
during the period beginning on the date hereof and terminating on the third
(3rd) anniversary of the date of the Private Equity Line Commitment Closing, the
Company agrees to pay to the Placement Agent a cash fee equal to five percent
(5%) of all amounts invested by any such Investor or Investors. In the event
that the Company accepts a Subsequent Investment without Swartz's advance
written permission, the Company agrees to pay to the Placement Agent a cash fee
equal to ten percent (10%) of all amounts invested by any such Investor or
Investors.

<PAGE>   66


     7.2 Specific Performance and Attorneys Fees. The Company acknowledges and
agrees that, if it breaches its obligations under Section 7.1, damages at law
will be an insufficient remedy to Placement Agent and that Placement Agent would
suffer irreparable damage as a result of such violation. Accordingly, it is
agreed that Placement Agent shall be entitled, upon application to a court of
competent jurisdiction, to obtain injunctive relief against the breaching party
to enforce the provisions of such sections, which injunctive relief shall be in
addition to any other rights or remedies available to Placement Agent. The
Company agrees to pay to Placement Agent (severally and not jointly) all costs
and expenses incurred by Placement Agent relating to the enforcement of the
terms of Section 7.1 hereof due to its own actions, whether by injunction, a
suit for damages or both, including reasonable fees and disbursements of counsel
(both at trial and in appellate proceedings).

     8. INDEMNIFICATION.

     8.1 The Company agrees to indemnify and hold harmless the Placement Agent,
each person who controls the Placement Agent within the meaning of Section 15 of
the Act and the Placement Agent's employees, accountants, attorneys and agents
(the "Placement Agent's Indemnitees") against any and all losses, claims,
damages or liabilities, joint or several, to which they or any of them may
become subject under the Act or the `34 Act or any other statute or at common
law and for any reasonable legal or other expenses (including the costs of any
investigation and preparation) incurred by them in connection with any
litigation, whether or not resulting in any liability, but only insofar as such
losses, claims, damages, liabilities and litigation arise out of or are based
upon (i) the Company's breach of its obligations under the Private Equity Line
Agreement to deliver shares of Common Stock to a Subscriber upon submission by
Subscriber of the required documentation, or (ii) any untrue statement of
material fact contained in the Offering Documents or any amendment or supplement
thereto or any application or other document filed in any state or jurisdiction
in order to qualify the Securities under the Blue Sky or securities laws
thereof, or the omission to state therein a material fact required to be stated
therein or necessary to make the statements therein, under the circumstances
under which they were made, not misleading, all as of the date of the Offering
Documents or of such amendment as the case may be, or (iii) any breach of any
representation, warranty or covenant made by the Company in this Agreement;
provided, however, that the indemnity agreement contained in this Section 8.1
shall not apply to amounts paid in settlement of any such litigation, if such
settlements are made without the consent of the Company (but no such settlement
may be made without the Company's prior written consent, which consent shall not
be unreasonably withheld), nor shall it apply to the Placement Agent's
Indemnitees in respect to any such losses, claims, damages or liabilities
arising out of or based upon any such untrue statement or alleged untrue
statement or any such omission or alleged omission, if such statement or
omission was made in reliance upon information furnished in writing to the
Company by the Placement Agent specifically for use in connection with the
preparation of the Offering Documents or any such amendment or supplement
thereto or any application or other


                                       11

<PAGE>   67


document filed in any state or jurisdiction in order to qualify the Securities
under the Blue Sky or securities law thereof. This indemnity agreement is in
addition to any other liability which the Company may otherwise have to the
Placement Agent's Indemnitees. The Placement Agent's Indemnitees agree, within
ten (10) days after the receipt by them of written notice of the commencement of
any action against them in respect to which indemnity may be sought from the
Company under this Section 8.1, to notify the Company in writing of the
commencement of such action; provided, however, that the failure of the
Placement Agent's Indemnitees to notify the Company of any such action shall not
relieve the Company from any liability which it may have to the Placement
Agent's Indemnitees on account of the indemnity agreement contained in this
Section 8.1, except with respect to any failure which irreparably prejudices the
Company or causes an event of adjudication materially adverse to the Company.
The Company shall not be relieved from any other liability which it may have to
the Placement Agent's Indemnitees, and if the Placement Agent's Indemnitees
shall notify the Company of the commencement thereof, the Company shall be
entitled to participate in (and, to the extent that the Company shall wish, to
direct) the defense thereof at its own expense, but such defense shall be
conducted by counsel of recognized standing and reasonably satisfactory to the
Placement Agent's Indemnitees, defendant or defendants, in such litigation. The
Company agrees to notify the Placement Agent's Indemnitees promptly of the
commencement of any litigation or proceedings against the Company or any of the
Company's officers or directors of which the Company may be advised in
connection with the issue and sale of any of the Securities and to furnish to
the Placement Agent's Indemnitees, at their request, copies of all pleadings
therein and to permit the Placement Agent's Indemnitees to be observers therein
and apprise the Placement Agent's Indemnitees of all developments therein, all
at the Company's expense.

     9. LIQUIDATED DAMAGES. Company and Placement Agent both acknowledge that it
would be extremely impractical and difficult to ascertain the actual damages to
be suffered by Company if Placement Agent is found by an arbitrator or a court
of competent jurisdiction to have breached any of the representations,
warranties and covenants contained in Section 13 of this instrument.
Accordingly, should a breach of the representations of Section 13 be proven and
Placement Agent found liable for said breach, Company and Placement Agent hereby
agree that the damages shall be fixed at no more than $100,000, inclusive of all
attorney's fees and cost of court. This provision is not to be construed as a
penalty, but as full liquidated damages under Georgia law.

     10. EFFECTIVENESS OF AGREEMENT. This Agreement shall become effective (i)
at 9:00 A.M., Atlanta, Georgia time, on the date hereof or (ii) upon release by
the Placement Agent of the Private Equity Line Agreement for offering after the
date hereof, whichever occurs first. The Placement Agent agrees to notify the
Company immediately after the Placement Agent shall have taken any action by
such release or otherwise wherein this Agreement shall have become effective.

     11. CONDITIONS OF THE PLACEMENT AGENT'S OBLIGATIONS. The Placement Agent's
obligations to act as agent of the Company hereunder and to find purchasers for


                                       12

<PAGE>   68


the Private Equity Line Agreement shall be subject to the accuracy, as of any
Closing Date, of the representations and warranties on the part of the Company
herein contained, to the fulfillment of or compliance by the Company with all
covenants and conditions hereof, and to the following additional conditions:

     11.1 Counsel to the Placement Agent shall not have objected in writing or
shall not have failed to give his consent to the Offering Documents (which
objection or failure to give consent shall not have been done unreasonably).

     11.2 The Placement Agent shall not have disclosed to the Company that the
Offering Documents, or any amendment thereof or supplement thereto, contains an
untrue statement of fact, which, in the opinion of counsel to the Placement
Agent, is material, or omits to state a fact, which, in the opinion of such
counsel, is material and is required to be stated therein, or is necessary to
make the statements therein, under the circumstances in which they were made,
not misleading.

     11.3 Between the date hereof and any Closing Date, the Company shall not
have sustained any loss on account of fire, explosion, flood, accident, calamity
or any other cause of such character as would materially adversely affect its
business or property considered as an entire entity, whether or not such loss is
covered by insurance.

     11.4 Except as set forth in the Disclosure Documents to the Private Equity
Line Agreement, during the time period between the date hereof and any Closing
Date, there shall be no litigation instituted or threatened against the Company,
and there shall be no proceeding instituted or threatened against the Company
before or by any federal or state commission, regulatory body or administrative
agency or other governmental body, domestic or foreign, wherein an unfavorable
ruling, decision or finding would materially adversely affect the business,
franchises, license, permits, operations or financial condition or income of the
Company considered as an entity.

     11.5 Except as contemplated herein or as set forth in the Offering
Documents, during the period subsequent to the most recent financial statements
contained in the Offering Documents, if any, and prior to any Closing Date, the
Company (i) shall have conducted its business in all material respects in the
usual and ordinary manner as the same is being conducted as of the date hereof
and (ii) except in the ordinary course of business, the Company shall not have
incurred any liabilities or obligations (direct or contingent) or disposed of
any assets, or entered into any material transaction or suffered or experienced
any substantially adverse change in its condition, financial or otherwise. At
any Closing Date, the equity account of the Company shall be substantially the
same as reflected in the most recent balance sheet contained in the Offering
Documents except for reductions for matters discussed in the Private Equity Line
Agreement and without considering the proceeds from the sale of the Securities
other than as may be set forth in the Offering Documents.


                                       13

<PAGE>   69


     11.6 The authorization of the Securities by the Company and all proceedings
and other legal matters incident thereto and to this Agreement shall be
reasonably satisfactory in all material respects to counsel to the Placement
Agent, who shall have furnished the Placement Agent on any Closing Date with
such favorable opinion with respect to the sufficiency of all corporate
proceedings and other legal matters relating to this Agreement as the Placement
Agent may reasonably require, and the Company shall have furnished such counsel
such documents as he may have requested to enable him to pass upon the matters
referred to in this subparagraph.

     11.7 The Company shall have furnished to the Placement Agent the opinion,
dated on any Closing Date, addressed to the Placement Agent, from counsel to the
Company, as required by the Private Equity Line Agreement in substantially the
form attached to the Private Equity Line Agreement as Exhibit D.

     11.8 The Company shall have furnished to the Placement Agent a due
diligence back up certificate signed by the Chief Executive Officer and the
Chief Financial Officer of the Company (a copy of which is attached hereto as
Exhibit C), dated as of any Closing Date, to the effect that:

     (i) the representations and warranties of the Company in this Agreement are
true and correct in all material respects at and as of any Closing Date (other
than representations and warranties which by their terms are specifically
limited to a date other than any such Closing Date), and the Company has
complied with all the agreements and has satisfied all the conditions on its
part to be performed or satisfied at or prior to any Closing Date;

     (ii) the Company has carefully examined the Offering Documents, and any
amendments and supplements thereto, and, to the best of its knowledge, all
statements contained in the Offering Documents, and any amendments and
supplements thereto, are true and correct, and neither the Offering Documents,
nor any amendment or supplement thereto, includes any untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein under the circumstances in which they
were made not misleading, and since the date hereof, there has occurred no event
required to be set forth in an amended or supplemented Offering Documents, which
has not been set forth; except as set forth in the Offering Documents, since the
respective dates as of which the periods for which the information is given in
the Offering Documents and prior to the date of such certificate, (a) there has
not been any material adverse change, financial and otherwise, in the affairs of
condition of the Company, and (b) except as disclosed in the Offering Documents,
the Company has not incurred any material liabilities, direct or contingent, or

business; and

     12 TERMINATION.

     12.1 This Agreement may be terminated by the Placement Agent by notice to

     13. PLACEMENT AGENT'S REPRESENTATIONS, WARRANTIES AND COVENANTS.

The Placement Agent  represents and warrants to and agrees with
the Company that:


                                       15

<PAGE>   71


     13.1 The Placement Agent is a limited liability company duly organized and
existing under the laws of the state of Georgia. The Placement Agent is an OSJ
branch office of Dunwoody Brokerage Services, Inc., a licensed NASD
broker-dealer, and a member of SIPC.

     13.2 There is not now pending or threatened or to the Placement Agent's
knowledge, contemplated against the Placement Agent any action or proceeding of
which the Placement Agent has been advised, either in any court of competent
jurisdiction, before the Commission or before any state securities commission or
the NASD, concerning the Placement Agent's activities which would impair the
ability of the Placement Agent to conduct the Offering as contemplated by this
Agreement.

     13.3 In the event any action or proceeding of the type referred to in
Section 13.2 above shall be instituted or threatened against the Placement Agent
at any time prior to any Closing Date or, in the event there shall be filed by
or against the Placement Agent in any court, pursuant to any federal, state,
local or municipal statute, a petition in bankruptcy or insolvency or for
reorganization or for the appointment of a receiver or trustee of its assets or
if the Placement Agent makes an assignment for the benefit of creditors, the
Company shall have the right, on three (3) days' written notice to the Placement
Agent, to terminate this Agreement without any liability to the Placement Agent
of any kind, except for the payment of all expenses provided herein.

     13.4 Placement Agent understands and acknowledges that prior to issuance,
the Private Equity Line Agreement is not being registered under the Act, and
that the Offering is to be conducted pursuant to Regulation D under the
Securities Act of 1933, as amended, (the "Act"). Accordingly, in conducting its
activities under this Agreement:

     (a) Placement Agent has not offered or sold and will not offer or sell the
Private Equity Line Agreement to any investor which Placement Agent does not
have reasonable grounds to believe, or does not believe, is an "Accredited
Investor," within the meaning of Regulation D under the Act.

     (b) Placement Agent has not, nor has any person or entity acting on its
behalf, conducted or will conduct any general solicitation (as that term is used
in Rule 502(c) of Regulation D) or general advertising with respect to the
Private Equity Line Agreement.

     (c) Placement Agent will not solicit or accept the subscription of any
person unless immediately before accepting such subscription Placement Agent has
reasonable grounds to believe and does believe that (i) such person is an
Accredited Investor and (ii) all representations made and information furnished
by such person in the Private Equity Line Agreement and related documents are
true and correct in all material respects.


                                       16

<PAGE>   72


     (d) Placement Agent will not solicit any purchasers of the Private Equity
Line Agreement unless the Offering Documents are furnished to such prospective
purchaser.

     (e) Upon notice from the Company that the Offering Documents are required
to be amended or supplemented, Placement Agent will immediately cease use of the
Offering Documents until Placement Agent has received such amendment or
supplement and thereafter will make use of the Offering Documents only as so
amended or supplemented, and Placement Agent will deliver a copy of such
amendment or supplement to each prospective investor to whom a copy of the
Offering Documents had previously been delivered (and who has not returned such
copy).

     (f) Placement Agent will use its best efforts to conduct the offering of
the Private Equity Line Agreement in a manner that will allow the availability
of the private offering exemption from federal securities regulation provided by
Regulation D promulgated under the Securities Act of 1933, as amended.

     (g) Placement Agent will notify the Company in writing promptly when any
event shall have occurred during the Offering Period as a result of which any
representation or warranty of the Placement Agent herein would not be true.

     13.5 Neither the Placement Agent nor any of its Affiliates will take any
action which will impair the effectiveness of the transactions contemplated by
this Agreement.

     13.6 All corporate actions by Placement Agent required for the execution,
delivery and performance of this Agreement have been taken. The execution and
delivery of this Agreement by the Placement Agent, the observance and
performance thereof, and the consummation of the transactions contemplated
herein or in the Offering Documents do not and will not constitute a material
breach of, or a material default under, any instrument or agreement by which the
Placement Agent is bound, and does not and will not, to the best of the
Placement Agent's knowledge, contravene any existing law, decree or order
applicable to it. This Agreement constitutes a valid and binding agreement of
Placement Agent, enforceable in accordance with its terms.

     13.7 Placement Agent understands that the Company is relying upon Placement
Agent's representations and warranties in connection with the Offering and the
sale of the Private Equity Line Agreement contemplated by this Agreement.

     13.8 Placement Agent's representations and warranties under this Section 13
shall be true and correct as of any Closing, and shall survive such Closing.

     13.9 Upon closing of the Offering and with the Company's prior written
approval for each such service to be provided, Placement Agent agrees to provide
the


                                       17

<PAGE>   73


following services (the "PLUS Package Aftermarket Services") for a period of one
(1) year following the date hereof (service may be provided for periods
following one (1) year subject to subsequent agreement between Company and

other office or agency as the Company may designate in writing, by overnight

Transfer Agent by facsimile (such surrender and payment of the Exercise Price
hereinafter called the "Exercise of this Warrant").

     (b) Date of Exercise. The "Date of Exercise" of the Warrant shall be
defined as the date that the advance copy of the completed and executed Exercise
Form is sent by facsimile to the Company, provided that the original Warrant and
Exercise Form are received by the Company as soon as practicable thereafter.
Alternatively, the Date of Exercise shall be defined as the date the original

     (c) Cancellation of Warrant. This Warrant shall be canceled upon the

terms identical to this Warrant) representing any unexercised portion of this
Warrant in addition to such Common Stock.

     (d) Holder of Record. Each person in whose name any Warrant for shares of
Common Stock is issued shall, for all purposes, be deemed to be the Holder of
record of such shares on the Date of Exercise of this Warrant, irrespective of
the date of delivery of the Common Stock purchased upon the Exercise of this
Warrant. Nothing in this Warrant shall be construed as conferring upon Holder
any rights as a stockholder of the Company.

     (e) Limitation on Exercise. Notwithstanding anything to the contrary
contained herein, this Warrant may not be exercised by the Warrant Holder to the
extent that, after giving effect to Warrant Shares to be issued pursuant to an
Exercise Form, the total number of shares of Common Stock deemed beneficially
owned by such Holder (other than by virtue of ownership of this Warrant, or
ownership of other securities that have limitations on the Holder's rights to
convert or exercise similar to the limitations set forth herein), together with
all shares of Common Stock deemed beneficially owned by the Holder's
"affiliates" (as defined in Rule 144 of the Securities Act) that would be
aggregated for purposes of determining whether a group under Section 13(d) of
the Securities Exchange Act of 1934, as amended (the "Exchange Act") exists,
would exceed 9.9%; provided that (w) each Warrant Holder shall have the right at
any time and from time to time to reduce such percentage from 9.9% immediately
upon notice to the Company or in the event of a Change in Control Transaction,
as defined below, (x) each Warrant Holder shall have the right at any time and
from time to time to increase such percentage from 9.9% or otherwise waive in
whole or in part the restrictions of this Section 2(e) upon 61 days' prior
notice to the Company or immediately in the event of a Change in Control
Transaction, (y) each Warrant Holder can make subsequent adjustments pursuant to
(w) or (x) any number of times from time to time (which adjustment shall be
effective immediately if it results in a decrease in the percentage or shall be
effective upon 61 days' prior written notice or immediately in the event of a
Change in Control Transaction if it results in an increase in percentage) and
(z) each Warrant Holder may eliminate or reinstate this limitation at any time
and from time to time (which elimination will be effective upon 61 days' prior
notice and which reinstatement will be effective immediately). Without limiting
the foregoing, in the event of a Change in Control Transaction, any holder may
reinstate immediately (in whole or in part) the requirement that any increase in
the percentage be subject to 61 days' prior written notice, notwithstanding such
Change in Control Transaction, without imposing


                                       2

<PAGE>   82

such requirement on, or otherwise changing such Holder's rights with respect to,
any other Change in Control Transaction. For this purpose, any material
modification of the terms of a Change in Control Transaction will be deemed to
create a new Change in Control Transaction. A "Change in Control Transaction"
will be deemed to have occurred upon the earlier of the announcement or
consummation of a transaction or series of transactions involving (x) any
consolidation or merger of the Company with or into any other corporation or
other entity or person (whether or not the Company is the surviving
corporation), or any other corporate reorganization or transaction or series of
related transactions in which in excess of 50% of the Company's voting power is
transferred through a merger, consolidation, tender offer or similar
transaction, or (y) in excess of 50% of the Corporation's Board of Directors
consists of directors not nominated by the prior Board of Directors of the
Company, or (z) any person (as defined in Section 13(d) of the Exchange Act),
together with its affiliates and associates (as such terms are defined in Rule
405 under the Act), beneficially owns or is deemed to beneficially own (as
described in Rule 13d-3 under the Exchange Act without regard to the 60-day
exercise period) in excess of 50% of the Company's voting power. The delivery of
an Exercise Form by the Warrant Holder shall be deemed a representation by such
Holder that it is in compliance with this paragraph. Notwithstanding anything in
this subsection (e), the exercise of this Warrant may only be deferred until
____________ ___, 20__.

     3. Payment of Warrant Exercise Price.

     The Exercise Price ("Exercise Price") shall equal $_________.

     Payment of the Exercise Price may be made by either of the following, or a
combination thereof, at the election of Holder:

     (i) Cash Exercise: cash, bank or cashiers check or wire transfer; or

     (ii) Cashless Exercise: subject to the last sentence of this Section 3,
surrender of this Warrant at the principal office of the Company together with
notice of cashless election, in which event the Company shall issue Holder a
number of shares of Common Stock computed using the following formula:

                                X = Y (A-B)/A

where:   X = the number of shares of Common Stock to be issued to Holder.

         Y = the number of shares of Common Stock for which this Warrant is
being exercised.

                  A = the Market Price of one (1) share of Common Stock (for
                  purposes of this Section 3(ii), the "Market Price" shall be
                  defined as the average Closing Bid Price of the Common Stock
                  for the five (5) trading days prior to the Date of Exercise of
                  this Warrant (the "Average Closing Price"), as reported by the
                  National Association of Securities Dealers Automated Quotation
                  System ("Nasdaq") Small Cap Market, or if the Common Stock is
                  not traded on the Nasdaq Small Cap Market, the Average Closing
                  Price in any other over-the-counter market; provided, however,
                  that if the Common Stock is listed on a stock exchange, the
                  Market Price shall be the Average Closing Price on such
                  exchange for the five (5) trading days prior to the date of
                  exercise of the Warrants. If the Common Stock is/was not
                  traded during the five (5) trading days prior to the Date of
                  Exercise, then the closing price for the last publicly traded
                  day shall be deemed to be the


                                       3

<PAGE>   83

                  closing price for any and all (if applicable) days during such
                  five (5) trading day period.

                  B = the Exercise Price.

For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is intended,
understood and acknowledged that the Common Stock issuable upon exercise of this
Warrant in a cashless exercise transaction shall be deemed to have been acquired
at the time this Warrant was issued. Moreover, it is intended, understood and
acknowledged that the holding period for the Common Stock issuable upon exercise
of this Warrant in a cashless exercise transaction shall be deemed to have
commenced on the date this Warrant was issued.

     For purposes hereof, the term "Closing Bid Price" shall mean the closing
bid price on the National Market System ("NMS"), the New York Stock Exchange,
the Nasdaq Small Cap Market, or the OTC Bulletin Board, or if no longer traded
on the NMS, the New York Stock Exchange, the Nasdaq Small Cap Market, or the OTC
Bulletin Board, the "Closing Bid Price" shall equal the closing price on the
principal national securities exchange or the over-the-counter system on which
the Common Stock is so traded and, if not available, the mean of the high and
low prices on the principal national securities exchange or the National
Securities Exchange on which the Common Stock is so traded.


     4. Transfer and Registration.

     (a) Transfer Rights. Subject to the provisions of Section 8 of this
Warrant, this Warrant may be transferred on the books of the Company, in whole
or in part, in person or by attorney, upon surrender of this Warrant properly
completed and endorsed. This Warrant shall be canceled upon such surrender and,
as soon as practicable thereafter, the person to whom such transfer is made
shall be entitled to receive a new Warrant or Warrants as to the portion of this
Warrant transferred, and Holder shall be entitled to receive a new Warrant as to
the portion hereof retained.

     (b) Registrable Securities. The Common Stock issuable upon the exercise of
this Warrant constitutes "Registrable Securities" under that certain
Registration Rights Agreement dated on or about September ___, 1998 between the
Company and certain investors and, accordingly, has the benefit of the
registration rights pursuant to that agreement.

     5. Anti-Dilution Adjustments.

     (a) Stock Dividend. If the Company shall at any time declare a dividend
payable in shares of Common Stock, then Holder, upon Exercise of this Warrant
after the record date for the determination of holders of Common Stock entitled
to receive such dividend, shall be entitled to receive upon Exercise of this
Warrant, in addition to the number of shares of Common Stock as to which this
Warrant is exercised, such additional shares of Common Stock as such Holder
would have received had this Warrant been exercised immediately prior to such
record date and the Exercise Price will be proportionately adjusted.

     (b) Recapitalization or Reclassification. If the Company shall at any time
effect a recapitalization, reclassification or other similar transaction of such
character that the shares of Common Stock shall be changed into or become
exchangeable for a larger or smaller number of shares, then upon the effective
date thereof, the number of shares of


                                       4

<PAGE>   84


Common Stock which Holder shall be entitled to purchase upon Exercise of this
Warrant shall be increased or decreased, as the case may be, in direct
proportion to the increase or decrease in the number of shares of Common Stock
by reason of such recapitalization, reclassification or similar transaction, and
the Exercise Price shall be, in the case of an increase in the number of shares,
proportionally decreased and, in the case of decrease in the number of shares,
proportionally increased. The Company shall give Holder the same notice it
provides to holders of Common Stock of any transaction described in this Section
5(b).

     (c) Distributions. If the Company shall at any time distribute for no
consideration to holders of Common Stock cash, evidences of indebtedness or
other securities or assets (other than cash dividends or distributions payable
out of earned surplus or net profits for the current or preceding years) then,
in any such case, Holder shall be entitled to receive, upon Exercise of this
Warrant, with respect to each share of Common Stock issuable upon such exercise,
the amount of cash or evidences of indebtedness or other securities or assets
which Holder would have been entitled to receive with respect to each such share
of Common Stock as a result of the happening of such event had this Warrant been
exercised immediately prior to the record date or other date fixing shareholders
to be affected by such event (the "Determination Date") or, in lieu thereof, if
the Board of Directors of the Company should so determine at the time of such
distribution, a reduced Exercise Price determined by multiplying the Exercise
Price on the Determination Date by a fraction, the numerator of which is the
result of such Exercise Price reduced by the value of such distribution
applicable to one share of Common Stock (such value to be determined by the
Board of Directors of the Company in its discretion) and the denominator of
which is such Exercise Price.

     (d) Notice of Consolidation or Merger. In the event of a merger,
consolidation, exchange of shares, recapitalization, reorganization, or other
similar event, as a result of which shares of Common Stock shall be changed into
the same or a different number of shares of the same or another class or classes
of stock or securities or other assets of the Company or another entity or there
is a sale of all or substantially all the Company's assets (a "Corporate
Change"), then this Warrant shall be exerciseable into such class and type of
securities or other assets as Holder would have received had Holder exercised
this Warrant immediately prior to such Corporate Change; provided, however, that
Company may not affect any Corporate Change unless it first shall have given
thirty (30) days notice to Holder hereof of any Corporate Change.

     (e) Exercise Price Adjusted. As used in this Warrant, the term "Exercise
Price" shall mean the purchase price per share specified in Section 3 of this
Warrant, until the occurrence of an event stated in subsection (a), (b) or (c)
of this Section 5, and thereafter shall mean said price as adjusted from time to
time in accordance with the provisions of said subsection. No such adjustment
under this Section 5 shall be made unless such adjustment would change the
Exercise Price at the time by $.01 or more; provided, however, that all
adjustments not so made shall be deferred and made when the aggregate thereof
would change the Exercise Price at the time by $.01 or more. No adjustment made
pursuant to any provision of this Section 5 shall have the net effect of
increasing the Exercise Price. The number of shares of Common Stock subject
hereto shall increase proportionately with each decrease in the Exercise Price.

     (f) Adjustments: Additional Shares, Securities or Assets. In the event that
at any time, as a result of an adjustment made pursuant to this Section 5,
Holder shall, upon Exercise of this Warrant, become entitled to receive shares
and/or other securities or assets (other than Common Stock) then, wherever
appropriate, all references herein to shares of Common Stock shall be deemed to
refer to and include such shares and/or other securities or assets; and 
thereafter the number of such shares and/or other securities or


                                       5

<PAGE>   85

assets shall be subject to adjustment from time to time in a manner and upon
terms as nearly equivalent as practicable to the provisions of this Section 5.


                                       6

<PAGE>   86


     6. Fractional Interests.

     No fractional shares or scrip representing fractional shares shall be
issuable upon the Exercise of this Warrant, but on Exercise of this Warrant,
Holder may purchase only a whole number of shares of Common Stock. If, on
Exercise of this Warrant, Holder would be entitled to a fractional share of
Common Stock or a right to acquire a fractional share of Common Stock, such
fractional share shall be disregarded and the number of shares of Common Stock
issuable upon exercise shall be the next higher number of shares.

     7. Reservation of Shares.

     The Company shall at all times reserve for issuance such number of
authorized and unissued shares of Common Stock (or other securities substituted
therefor as herein above provided) as shall be sufficient for the Exercise of
this Warrant and payment of the Exercise Price. The Company covenants and agrees
that upon the Exercise of this Warrant, all shares of Common Stock issuable upon
such exercise shall be duly and validly issued, fully paid, nonassessable and
not subject to preemptive rights, rights of first refusal or similar rights of
any person or entity.

     8. Restrictions on Transfer.

     (a) Registration or Exemption Required. This Warrant has been issued in a
transaction exempt from the registration requirements of the Act by virtue of
Regulation D and exempt from state registration under applicable state laws. The
Warrant and the Common Stock issuable upon the Exercise of this Warrant may not
be pledged, transferred, sold or assigned except pursuant to an effective
registration statement or an exemption to the registration requirements of the
Act and applicable state laws.

     (b) Assignment. If Holder can provide the Company with reasonably
satisfactory evidence that the conditions of (a) above regarding registration or
exemption have been satisfied, Holder may sell, transfer, assign, pledge or
otherwise dispose of this Warrant, in whole or in part. Holder shall deliver a
written notice to Company, substantially in the form of the Assignment attached
hereto as Exhibit B, indicating the person or persons to whom the Warrant shall
be assigned and the respective number of warrants to be assigned to each
assignee. The Company shall effect the assignment within ten (10) days, and
shall deliver to the assignee(s) designated by Holder a Warrant or Warrants of
like tenor and terms for the appropriate number of shares.

     9. Benefits of this Warrant.

     Nothing in this Warrant shall be construed to confer upon any person other
than the Company and Holder any legal or equitable right, remedy or claim under
this Warrant and this Warrant shall be for the sole and exclusive benefit of the
Company and Holder.

     10. Applicable Law.

     This Warrant is issued under and shall for all purposes be governed by and
construed in accordance with the laws of the state of Delaware, without giving
effect to conflict of law provisions thereof.

     11. Loss of Warrant.

mutilation of this Warrant, and (in the case of loss, theft or destruction) of
indemnity or security reasonably satisfactory to the Company, and upon surrender
and cancellation of this Warrant, if mutilated, the Company shall execute and
deliver a new Warrant of like tenor and date.

     12. Notice or Demands.

                        WARRANT TO PURCHASE COMMON STOCK
                                       OF
                                  VIRAGEN, INC.

     THIS CERTIFIES that Swartz Private Equity, LLC or any subsequent holder
hereof ("Holder"), has the right to purchase from VIRAGEN, INC., a Delaware
corporation (the "Company"), up to "N" fully paid and nonassessable shares,
wherein "N" is defined below, of the Company's common stock, $.01 par value per
share ("Common Stock"), subject to adjustment as provided herein, at a price
equal to the Exercise Price as defined in Section 3 below, at any time beginning
on the Date of Issuance (defined below) and ending at 5:00 p.m., New York, New
York time, on ___________ ___, 20___ (the "Exercise Period"); provided, that "N"
shall equal ten percent (10%) of the number of shares of Common Stock purchased
by the Holder pursuant to that certain Regulation D Common Stock Equity Line
Subscription Agreement (the "Subscription Agreement") by and between the Holder
and Company during the six (6) month period immediately preceding any Six Month

     Holder agrees with the Company that this Warrant to Purchase Common Stock
of Viragen, Inc. (this "Warrant") is issued and all rights hereunder shall be
held subject to all of the conditions, limitations and provisions set forth

("Date of Issuance").

     2. Exercise.

                                      

<PAGE>   91


     (a) Manner of Exercise. During the Exercise Period, this Warrant may be
exercised as to all or any lesser number of full shares of Common Stock covered
hereby (the "Warrant Shares") upon surrender of this Warrant, with the Exercise
Form attached hereto as Exhibit A (the "Exercise Form") duly completed and
executed, together with the full Exercise Price (as defined below) for each
share of Common Stock as to which this Warrant is exercised, at the office of
the Company, Attention: Dennis W. Healey, Executive VP/CFO, 865 SW 78th Avenue,
Suite 100, Plantation, FL 33324, Telephone No. (954) 233-8746, Telecopy No.
(954) 233-1416, or at such other office or agency as the Company may designate
in writing, by overnight mail, with an advance copy of the Exercise Form sent to
the Company and its Transfer Agent by facsimile (such surrender and payment of
the Exercise Price hereinafter called the "Exercise of this Warrant").

     (b) Date of Exercise. The "Date of Exercise" of the Warrant shall be
defined as the date that the advance copy of the completed and executed Exercise
Form is sent by facsimile to the Company, provided that the original Warrant and
Exercise Form are received by the Company as soon as practicable thereafter.
Alternatively, the Date of Exercise shall be defined as the date the original
Exercise Form is received by the Company, if Holder has not sent advance notice
by facsimile.

     (c) Cancellation of Warrant. This Warrant shall be canceled upon the
Exercise of this Warrant, and, as soon as practical after the Date of Exercise,
Holder shall be entitled to receive Common Stock for the number of shares
purchased upon such Exercise of this Warrant, and if this Warrant is not
exercised in full, Holder shall be entitled to receive a new Warrant (containing
terms identical to this Warrant) representing any unexercised portion of this
Warrant in addition to such Common Stock.

     (d) Holder of Record. Each person in whose name any Warrant for shares of
Common Stock is issued shall, for all purposes, be deemed to be the Holder of
record of such shares on the Date of Exercise of this Warrant, irrespective of
the date of delivery of the Common Stock purchased upon the Exercise of this
Warrant. Nothing in this Warrant shall be construed as conferring upon Holder
any rights as a stockholder of the Company.

     (e) Limitation on Exercise. Notwithstanding anything to the contrary
contained herein, this Warrant may not be exercised by the Warrant Holder to the
extent that, after giving effect to Warrant Shares to be issued pursuant to an
Exercise Form, the total number of shares of Common Stock deemed beneficially
owned by such Holder (other than by virtue of ownership of this Warrant, or
ownership of other securities that have limitations on the Holder's rights to
convert or exercise similar to the limitations set forth herein), together with
all shares of Common Stock deemed beneficially owned by the Holder's
"affiliates" (as defined in Rule 144 of the Securities Act) that would be
aggregated for purposes of determining whether a group under Section 13(d) of
the Securities Exchange Act of 1934, as amended (the "Exchange Act") exists,
would exceed 9.9%; provided that (w) each Warrant Holder shall have the right at
any time and from time to time to reduce such percentage from 9.9% immediately
upon notice to the Company or in the event of a Change in Control Transaction,
as defined below, (x) each Warrant Holder shall have the right at any time and
from time to time to increase such percentage from 9.9% or otherwise waive in
whole or in part the restrictions of this Section 2(e) upon 61 days' prior
notice to the Company or immediately in the event of a Change in Control
Transaction, (y) each Warrant Holder can make subsequent adjustments pursuant to
(w) or (x) any number of times from time to time (which adjustment shall be
effective immediately if it results in a decrease in the percentage or shall be
effective upon 61 days' prior written notice or immediately in the event of a
Change in Control Transaction if it results in an increase in percentage) and
(z) each Warrant Holder may eliminate or reinstate this limitation at any time
and from time to time (which elimination will be effective upon 61 days' prior
notice and which


                                       2

<PAGE>   92


reinstatement will be effective immediately). Without limiting the foregoing, in
the event of a Change in Control Transaction, any holder may reinstate
immediately (in whole or in part) the requirement that any increase in the
percentage be subject to 61 days' prior written notice, notwithstanding such
Change in Control Transaction, without imposing such requirement on, or
otherwise changing such Holder's rights with respect to, any other Change in
Control Transaction. For this purpose, any material modification of the terms of
a Change in Control Transaction will be deemed to create a new Change in Control
Transaction. A "Change in Control Transaction" will be deemed to have occurred
upon the earlier of the announcement or consummation of a transaction or series
of transactions involving (x) any consolidation or merger of the Company with or
into any other corporation or other entity or person (whether or not the Company
is the surviving corporation), or any other corporate reorganization or
transaction or series of related transactions in which in excess of 50% of the
Company's voting power is transferred through a merger, consolidation, tender
offer or similar transaction, or (y) in excess of 50% of the Corporation's Board
of Directors consists of directors not nominated by the prior Board of Directors
of the Company, or (z) any person (as defined in Section 13(d) of the Exchange
Act), together with its affiliates and associates (as such terms are defined in
Rule 405 under the Act), beneficially owns or is deemed to beneficially own (as
described in Rule 13d-3 under the Exchange Act without regard to the 60-day
exercise period) in excess of 50% of the Company's voting power. The delivery of
an Exercise Form by the Warrant Holder shall be deemed a representation by such
Holder that it is in compliance with this paragraph. Notwithstanding anything in
this subsection (e), the exercise of this Warrant may only be deferred until
______________ ___, 20___.

     3. Payment of Warrant Exercise Price.

     The Exercise Price shall equal $_______ per share ("Exercise Price").

     Payment of the Exercise Price may be made by either of the following, or a
combination thereof, at the election of Holder:

     (i) Cash Exercise: cash, bank or cashiers check or wire transfer; or

     (ii) Cashless Exercise: subject to the next to the last sentence of this
Section 3, surrender of this Warrant at the principal office of the Company
together with notice of cashless election, in which event the Company shall
issue Holder a number of shares of Common Stock computed using the following
formula:

                                 X = Y (A-B)/A

where:   X = the number of shares of Common Stock to be issued to Holder.

         Y = the number of shares of Common Stock for which this Warrant is
being exercised.

                  A = the Market Price of one (1) share of Common Stock (for
                  purposes of this Section 3(ii), the "Market Price" shall be
                  defined as the average closing bid price of the Common Stock
                  for the five (5) trading days prior to the Date of Exercise of
                  this Warrant (the "Average Closing Price"), as reported by the
                  National Association of Securities Dealers Automated Quotation
                  System ("Nasdaq") Small Cap Market, or if the Common Stock is
                  not traded on the Nasdaq Small Cap Market, the Average Closing
                  Price in any other over-the-counter market; provided, however,
                  that if the Common Stock is listed on a stock exchange, the
                  Market Price shall be the


                                       3

<PAGE>   93


                  Average Closing Price on such exchange for the five (5)
                  trading days prior to the date of exercise of the Warrants. If
                  the Common Stock is/was not traded during the five (5) trading
                  days prior to the Date of Exercise, then the closing price for
                  the last publicly traded day shall be deemed to be the closing
                  price for any and all (if applicable) days during such five
                  (5) trading day period.

                  B = the Exercise Price.

Notwithstanding anything to the contrary contained herein, this Warrant may not
be exercised in a cashless exercise transaction if, on the Date of Exercise, the
shares of Common Stock to be issued upon exercise of this Warrant would upon
such issuance (x) be immediately transferable in the United States free of any
restrictive legend, including without limitation under Rule 144; (y) be then
registered pursuant to an effective registration statement filed pursuant to
that certain Registration Rights Agreement dated on or about September ___, 1998
by and among the Company and certain investors; or (z) otherwise be registered
under the Securities Act of 1933, as amended.

For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is intended,
understood and acknowledged that the Common Stock issuable upon exercise of this
Warrant in a cashless exercise transaction shall be deemed to have been acquired
at the time this Warrant was issued. Moreover, it is intended, understood and
acknowledged that the holding period for the Common Stock issuable upon exercise
of this Warrant in a cashless exercise transaction shall be deemed to have
commenced on the date this Warrant was issued.

     4. Transfer and Registration.

     (a) Transfer Rights. Subject to the provisions of Section 8 of this
Warrant, this Warrant may be transferred on the books of the Company, in whole
or in part, in person or by attorney, upon surrender of this Warrant properly
completed and endorsed. This Warrant shall be canceled upon such surrender and,
as soon as practicable thereafter, the person to whom such transfer is made
shall be entitled to receive a new Warrant or Warrants as to the portion of this
Warrant transferred, and Holder shall be entitled to receive a new Warrant as to
the portion hereof retained.

     (b) Registrable Securities. The Common Stock issuable upon the exercise of
this Warrant constitutes "Registrable Securities" under that certain
Registration Rights Agreement dated on or about September ___, 1998 between the
Company and certain investors and, accordingly, has the benefit of the
registration rights pursuant to that agreement.

     5. Anti-Dilution Adjustments.

     (a) Stock Dividend. If the Company shall at any time declare a dividend
payable in shares of Common Stock, then Holder, upon Exercise of this Warrant
after the record date for the determination of holders of Common Stock entitled
to receive such dividend, shall be entitled to receive upon Exercise of this
Warrant, in addition to the number of shares of Common Stock as to which this
Warrant is exercised, such additional shares of Common Stock as such Holder
would have received had this Warrant been exercised immediately prior to such
record date and the Exercise Price will be proportionately adjusted.

     (b) Recapitalization or Reclassification. If the Company shall at any time
effect a recapitalization, reclassification or other similar transaction of such
character that


                                       4

<PAGE>   94


the shares of Common Stock shall be changed into or become exchangeable for a
larger or smaller number of shares, then upon the effective date thereof, the
number of shares of Common Stock which Holder shall be entitled to purchase upon
Exercise of this Warrant shall be increased or decreased, as the case may be, in
direct proportion to the increase or decrease in the number of shares of Common
Stock by reason of such recapitalization, reclassification or similar
transaction, and the Exercise Price shall be, in the case of an increase in the
number of shares, proportionally decreased and, in the case of decrease in the
number of shares, proportionally increased. The Company shall give Holder the
same notice it provides to holders of Common Stock of any transaction described
in this Section 5(b).

     (c) Distributions. If the Company shall at any time distribute for no
consideration to holders of Common Stock cash, evidences of indebtedness or
other securities or assets (other than cash dividends or distributions payable
out of earned surplus or net profits for the current or preceding years) then,
in any such case, Holder shall be entitled to receive, upon Exercise of this
Warrant, with respect to each share of Common Stock issuable upon such exercise,
the amount of cash or evidences of indebtedness or other securities or assets
which Holder would have been entitled to receive with respect to each such share
of Common Stock as a result of the happening of such event had this Warrant been
exercised immediately prior to the record date or other date fixing shareholders
to be affected by such event (the "Determination Date") or, in lieu thereof, if
the Board of Directors of the Company should so determine at the time of such
distribution, a reduced Exercise Price determined by multiplying the Exercise
Price on the Determination Date by a fraction, the numerator of which is the
result of such Exercise Price reduced by the value of such distribution
applicable to one share of Common Stock (such value to be determined by the
Board of Directors of the Company in its discretion) and the denominator of
which is such Exercise Price.

     (d) Notice of Consolidation or Merger. In the event of a merger,
consolidation, exchange of shares, recapitalization, reorganization, or other
similar event, as a result of which shares of Common Stock shall be changed into
the same or a different number of shares of the same or another class or classes
of stock or securities or other assets of the Company or another entity or there
is a sale of all or substantially all the Company's assets (a "Corporate
Change"), then this Warrant shall be exerciseable into such class and type of
securities or other assets as Holder would have received had Holder exercised
this Warrant immediately prior to such Corporate Change; provided, however, that
Company may not affect any Corporate Change unless it first shall have given
thirty (30) days notice to Holder hereof of any Corporate Change.

     (e) Exercise Price Adjusted. As used in this Warrant, the term "Exercise
Price" shall mean the purchase price per share specified in Section 3 of this
Warrant, until the occurrence of an event stated in subsection (a), (b) or (c)
of this Section 5, and thereafter shall mean said price as adjusted from time to
time in accordance with the provisions of said subsection. No such adjustment
under this Section 5 shall be made unless such adjustment would change the
Exercise Price at the time by $.01 or more; provided, however, that all
adjustments not so made shall be deferred and made when the aggregate thereof
would change the Exercise Price at the time by $.01 or more. No adjustment made
pursuant to any provision of this Section 5 shall have the net effect of
increasing the Exercise Price. The number of shares of Common Stock subject
hereto shall increase proportionately with each decrease in the Exercise Price.

     (f) Adjustments: Additional Shares, Securities or Assets. In the event that
at any time, as a result of an adjustment made pursuant to this Section 5,
Holder shall, upon Exercise of this Warrant, become entitled to receive shares
and/or other securities or assets (other than Common Stock) then, wherever
appropriate, all references herein to


                                       5

<PAGE>   95


shares of Common Stock shall be deemed to refer to and include such shares
and/or other securities or assets; and thereafter the number of such shares
and/or other securities or assets shall be subject to adjustment from time to
time in a manner and upon terms as nearly equivalent as practicable to the
provisions of this Section 5.

     6. Fractional Interests.

     No fractional shares or scrip representing fractional shares shall be
issuable upon the Exercise of this Warrant, but on Exercise of this Warrant,
Holder may purchase only a whole number of shares of Common Stock. If, on
Exercise of this Warrant, Holder would be entitled to a fractional share of
Common Stock or a right to acquire a fractional share of Common Stock, such
fractional share shall be disregarded and the number of shares of Common Stock
issuable upon exercise shall be the next higher number of shares.

     7. Reservation of Shares.

     The Company shall at all times reserve for issuance such number of
authorized and unissued shares of Common Stock (or other securities substituted
therefor as herein above provided) as shall be sufficient for the Exercise of
this Warrant and payment of the Exercise Price. The Company covenants and agrees
that upon the Exercise of this Warrant, all shares of Common Stock issuable upon
such exercise shall be duly and validly issued, fully paid, nonassessable and
not subject to preemptive rights, rights of first refusal or similar rights of
any person or entity.

     8. Restrictions on Transfer.

     (a) Registration or Exemption Required. This Warrant has been issued in a
transaction exempt from the registration requirements of the Act by virtue of
Regulation D and exempt from state registration under applicable state laws. The
Warrant and the Common Stock issuable upon the Exercise of this Warrant may not
be pledged, transferred, sold or assigned except pursuant to an effective
registration statement or an exemption to the registration requirements of the
Act and applicable state laws.

     (b) Assignment. If Holder can provide the Company with reasonably
satisfactory evidence that the conditions of (a) above regarding registration or
exemption have been satisfied, Holder may sell, transfer, assign, pledge or
otherwise dispose of this Warrant, in whole or in part. Holder shall deliver a
written notice to Company, substantially in the form of the Assignment attached
hereto as Exhibit B, indicating the person or persons to whom the Warrant shall
be assigned and the respective number of warrants to be assigned to each
assignee. The Company shall effect the assignment within ten (10) days, and
shall deliver to the assignee(s) designated by Holder a Warrant or Warrants of
like tenor and terms for the appropriate number of shares.

     9. Benefits of this Warrant.

     Nothing in this Warrant shall be construed to confer upon any person other
than the Company and Holder any legal or equitable right, remedy or claim under
this Warrant and this Warrant shall be for the sole and exclusive benefit of the
Company and Holder.

     10. Applicable Law.


                                       6

<PAGE>   96


     This Warrant is issued under and shall for all purposes be governed by and
construed in accordance with the laws of the state of Delaware, without giving
effect to conflict of law provisions thereof.

     11. Loss of Warrant.

     Upon receipt by the Company of evidence of the loss, theft, destruction or
mutilation of this Warrant, and (in the case of loss, theft or destruction) of
indemnity or security reasonably satisfactory to the Company, and upon surrender
and cancellation of this Warrant, if mutilated, the Company shall execute and
deliver a new Warrant of like tenor and date.

     12. Notice or Demands.

on the Company shall be sufficiently given or made if sent by certified or
registered mail, return receipt requested, postage prepaid, and addressed, until
