                               HIGH RISK FACTORS

         An investment in our common stock is very risky. You should be aware
you could lose the entire amount of your investment. Prior to making an
investment decision, you should carefully read this entire prospectus and
consider the following risk factors:

HISTORY OF LOSSES DUE TO LACK OF SALES AND REGULATORY APPROVAL

         Since the organization of Viragen, Inc., we have incurred operating
losses. The net loss for our fiscal year ended June 30, 1998 was $7,856,136. As
of March 31, 1999, our net loss for the nine month period then ended was
$7,490,642. At March 31, 1999, we had a total deficit since organization of
$47,357,982.

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

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

POSSIBLE NASDAQ DELISTING AND PENNY STOCK RULES MAY NEGATIVELY IMPACT THE
MARKET FOR OUR COMMON STOCK

         On December 16, 1998, we received notice from the Nasdaq Stock Market
that our common stock was in jeopardy of being delisted from the Nasdaq
National Market because our common stock failed to maintain a closing bid price
of $1.00 per share. We are in the process of soliciting proxies from our
stockholders, which if approved will give our board of directors the authority
to complete up to a 1 for 8 reverse stock split of our common stock. A reverse
stock split should assist in increasing the closing bid price of our common
stock above $1.00. However, we cannot assure you our stockholders will approve
the reverse stock split, or if the stock split is approved, whether it will
increase the closing bid price of our common stock above $1.00 for a sufficient
period of time. If we are delisted from Nasdaq, there could be less interest in
our stock as well as a more limited market. This could reduce the value of your
investment.

         If our common stock is delisted from the Nasdaq National Market System
and continues to trade at less than $5.00 per share, our common stock will most
likely be subject to the penny


                                       3
<PAGE>   6

stock rules under the Securities Exchange Act of 1934. Penny stocks generally
are equity securities with a price of less than $5.00 which do not trade on
certain national securities exchanges or are quoted on the Nasdaq National
Market System. The penny stock rules require broker-dealers, prior to a
transaction in a penny stock which is not exempt from the rules, to deliver a
standardized risk disclosure document prepared by the Securities and Exchange
Commission that provides information about penny stocks and the risks in the
penny stock market. The broker-dealer also must provide the customer with
current bid and offer quotations for the penny stock, the compensation of the
broker-dealer and its salesperson in the transaction, and monthly account
statements showing the market value of each penny stock held in the customer's
account. The bid and offer quotations, and the broker dealer and salesperson
compensation information, must be given to the customer orally or in writing
prior to completing the transaction and must be given to the customer in
writing before or with the customer's confirmation.

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

COMPETITION IN PHARMACEUTICAL INDUSTRY

         Competition for investment capital and market share in the
immunological and pharmaceutical products industry is intense. Our competitors,
which include major pharmaceutical companies, have more experience in research,
development and clinical testing of pharmaceutical and biomedical products. Our
competitors also have greater financial, marketing and human resources than
Viragen. Some of our competitors already have approvals for and are already
marketing synthetic products similar to our product. Competition is only
expected to increase in the future. If we are unable to compete with our
larger, more experienced competitors, we may be forced to terminate operations.

         Competition for funding in the pharmaceutical industry is also
intense. As explained above, we have no source of income and may not have
sufficient sources of income for a significant period of time, if ever.
Additional funds will be needed to conduct clinical trials so we can receive
regulatory approvals. We must obtain additional funding from outside sources to
conduct these trials. In the event we are unable to locate funding or obtain
funding on reasonable terms, we will most likely be required to terminate
operations. In that case, any investment in Viragen would be lost.


                                       4
<PAGE>   7

RISK OF TECHNOLOGICAL OBSOLESCENCE MAY AFFECT OUR ABILITY TO PRODUCE OUR
PRODUCT

         The research and development of natural interferon involves rapid
technological change. This change can severely affect the production methods,
costs, marketing and acceptance of biomedical products. We cannot be certain
that we will have the resources to keep pace with technological changes or that
products developed by our competitors will not make it difficult or impossible
to market our product. If we are unable to successfully market interferon, we
may be forced to terminate our operations.

GOVERNMENT REGULATION MAY AFFECT DEVELOPMENT AND DISTRIBUTION OF NATURAL
INTERFERON

         All pharmaceutical manufacturers are subject to state and federal
rules and regulations. In particular, we must comply with the United States
Food and Drug Administration guidelines governing the productivity, testing and
marketing. European Union regulatory authorities also impose regulations. These
rules and regulations are constantly changing, require costly compliance
measures and may restrict our ability to produce and distribute our natural
interferon product.

DIFFICULTY TESTING PRODUCT MAY PREVENT US FROM DEVELOPING INTERFERON

         Our ability to receive the approval of either the United States Food
and Drug Administration or the European Union regulatory authorities depends,
in part, on our ability to test natural interferon on human patients. If we are
unable to comply with United States and European Union regulations or are
prohibited from testing natural interferon on human patients, we will have to
terminate our operations which would result in a complete loss of your
investment.

UNCERTAINTY OF HEALTH CARE REFORM MEASURES AND THIRD PARTY REIMBURSEMENT

         Our ability to successfully market our products may depend on the
receipt of reimbursements from government health administration authorities,
private health coverage insurers and other organizations. The pricing of
products similar to those we produce or the amount of reimbursement available
from governmental agencies or third party insurers may affect our ability to
market our product or market our product at a profit.


                                       5
<PAGE>   8

RISK THAT PATENTS AND PROPRIETARY TECHNOLOGY MAY NOT PROVIDE PROTECTION

         We intend to rely, in part, on our proprietary technology for the
efficient and safe production of natural interferon that was developed by
Viragen's scientists. Viragen recently filed two patent applications relating
to our Omniferon(TM) production technology. We cannot assure you that our
production technology will enable us to either manufacture natural interferon
more efficiently and with less contaminants, or enable us to compete
effectively with our competitors. In addition, we may be damaged if we are
accused of misappropriating a competitor's proprietary technology even if these
claims are untrue. We cannot assure you that our patent applications will be
approved, and if granted, that these patents will provide necessary protection
to us.

TECHNOLOGY TRANSFERS TO THIRD PARTIES MAY NOT RESULT IN REVENUE TO US

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

EXPOSURE TO PRODUCT LIABILITY CLAIMS AND LIMITATIONS OF PRODUCT LIABILITY
INSURANCE

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

RELIANCE ON FOREIGN THIRD PARTY MANUFACTURER MAY DISRUPT OPERATIONS

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

                                       6
<PAGE>   9

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

RISK OF DEPENDENCE ON KEY PERSONNEL

         Our day-to-day operations are managed by Mr. Gerald Smith, our
Chairman of the Board and President, Mr. Dennis W. Healey, our Executive Vice
President, Treasurer and Chief Financial Officer, and Dr. D. Magnus Nicolson,
the Managing Director of Viragen (Scotland) Ltd. We have employment agreements
with Messrs. Smith, Healey and Nicolson which restrict competitive activities
by them during the term of their agreements and for a two-year period
thereafter. However, the loss of their services would have a negative effect on
our ability to conduct business. Our future success will greatly depend on our
ability to attract and retain additional skilled personnel in various phases of
our operations.

POSSIBLE ISSUANCE OF ADDITIONAL SHARES AND PAYMENT OF PENALTY FEES

         As described in the "Selling Security Holders" section of this
prospectus, we may be obligated to pay the selling security holders penalty
fees, in excess of the amount of their investment, and issue additional shares
of our common stock if we default on our obligations to the selling security
holders. If we are required to pay any penalty fees, our ability to finance our
current and future operations could be negatively affected. If we are required
to issue additional shares of our common stock, your ownership interest in us
may be significantly diluted.

IMPACT OF THE YEAR 2000 ON COMPUTER SYSTEMS

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

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

DILUTIVE EFFECTS OF TRANSACTION WITH SELLING SECURITY HOLDERS

         Based on the current market price of our common stock we may issue
approximately 6,000,000 shares of our common stock (or 9.2% of the issued and
outstanding common stock as of March 31, 1999) to the selling security holders.
The selling security holders may invest additional funds in Viragen on terms
virtually identical to those described in the "Selling Security Holders"
section of the prospectus. Because the price the selling security holders must
pay for those shares is based on the market price of our common stock on
various dates and due to the large percentage of shares of our common stock we
may sell to the selling security holders, you may experience substantial
dilution of your investment in us. In addition, sales of our share by the
selling security holders may depress the price of our stock in the market.

WE DO NOT EXPECT TO PAY DIVIDENDS IN THE FORESEEABLE FUTURE

         We have never paid cash dividends on our common stock and do not
expect to pay cash dividends on our common stock any time in the near future.
The future payment of dividends directly depends upon our future earnings,
capital requirements, financial requirements and other factors to be determined
by our Board of Directors. For the foreseeable future, any earnings from
operations will be used to finance our growth and will not be paid to our
common stockholders in the form of dividends. Since we do not anticipate paying
cash dividends on our common stock, return on your investment, if any, will
have to issue from sales by you of our common stock.

POSSIBLE RESALES OF SECURITIES BY CURRENT STOCKHOLDERS AND DEPRESSIVE EFFECT ON
MARKET

         As of March 31, 1999, we had 4,361,177 shares of common stock
outstanding which were "restricted securities" as that term is defined by Rule
144 under the Securities Act of 1933, as amended (the "Securities Act"). As of
March 31, 1999, we had options and warrants outstanding which if exercised would
result in 12,039,011 additional shares of our common stock outstanding. The
shares of common stock outstanding do not include shares of common stock that
may be issued on conversion of various options and warrants. Under Rule 144, a
person who holds restricted securities for a period of one year may sell a
limited number of shares to the public in ordinary brokerage transactions. Sales
under Rule 144 and sales of common stock covered by registration statements
filed by us such as shares covered by this prospectus may reduce the market
price of our common stock and increase the number of our publicly held
securities.

USE OF PREFERRED STOCK COULD BE USED TO RESIST TAKEOVERS AND MAY ALSO CAUSE
POTENTIAL ADDITIONAL DILUTION

         Our Certificate of Incorporation authorizes 1,000,000 shares of
preferred stock, of which at May 31, 1999, 2,650 shares of Series A Preferred
Stock and 11 shares of Series I Preferred


                                       8

Stock were issued and outstanding. Our Certificate of Incorporation gives our
Board of Directors the authority to issue preferred stock without approval of
our stockholders. We may issue additional shares of preferred stock to raise
money to finance our operations. We may authorize issuance of the preferred
stock in one or more series. In addition, we may set the dividend and
liquidation preferences, voting rights, conversion privileges, redemption terms
and other privileges and rights of the shares of each authorized series. The
issuance of large blocks of preferred stock could possibly have a dilutive
effect to our existing stockholders and negatively impact our existing
stockholders' liquidation preferences. In addition, while we include preferred
stock in our capitalization to improve our financial flexibility, we could
possibly issue our preferred stock to friendly third parties to preserve
control by present management in the event we become subject to a hostile
takeover that could ultimately benefit Viragen and Viragen's stockholders.

                                  THE COMPANY

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

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

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

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

                            SELLING SECURITY HOLDERS

TRANSACTION OVERVIEW

         On March 17, 1999, we entered into a purchase agreement with The
Isosceles Fund Limited and Cefeo Investments Limited. We signed an amended
agreement to the purchase agreement on June 16, 1999. The purchase agreement:

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

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

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

         At the same time we executed the purchase agreement, we entered into a
Memorandum of Agreement with Isosceles which gives us the option to sell
Isosceles an aggregate of up to $7,000,000 of additional notes and warrants in
two tranches, subject to the satisfactory completion of due diligence by
Isosceles.

THE NOTES

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

         OPTIONAL PRE-PAYMENT. At our option, we may pre-pay the notes at 120%
of their outstanding principal balance plus the accrued interest until July 7,
1999.

         MANDATORY REDEMPTION. If we do not obtain the approval of our
stockholders to complete up to a 1 for 4 reverse stock split of our outstanding
common stock by June 30, 1999, the note holders may require us to redeem an
amount of the notes, or any shares of our common stock issued to the note
holders upon conversion of the notes, necessary to permit:

         -        conversion of the remaining note(s);

         -        re-sale of the shares of our common stock issuable upon
                  conversion of the notes;

         -        issuance of additional shares; and

         -        exercise of the warrants


                                      14
<PAGE>   17

without violating NASDAQ rules. Any redemption we would be required to make
would be at a cash price equal to the greater of 125% of the face amount of the
notes or the aggregate conversion price paid for the shares of our common stock
issuable on conversion of the notes being redeemed plus all other fees
described below.

         CONVERSION. If we do not pre-pay or redeem the notes, then on the
trading day following sooner to occur of June 30, 1999 or the date a
registration statement registering the shares of common stock issuable upon
conversion of the notes becomes effective, one-half of the principal balance
and accrued interest on the notes will automatically convert into shares of our
common stock. In addition, 31 days after the date the first half of the
principal balance and accrued interest on the notes converts, the remaining
one-half of the principal balance and accrued interest on the notes will
automatically convert into shares of our common stock. The conversion price per
share will be the lesser of $0.50 or the lowest closing bid price of our
common stock during the ten consecutive trading days immediately preceding each
of the conversion dates. The number of shares of our common stock that will be
issued to each note holder on conversion will be determined by dividing the
principal balance and accrued interest on the notes by the conversion price in
effect on each conversion date.

         In addition to the shares issuable on conversion of the notes, the
note holders are entitled to receive additional shares of our common stock 31
days and again 61 days after the date the first one-half of the notes convert
into shares of our common stock. The number of additional shares the note
holders are entitled to receive will be calculated by subtracting 1 from the
quotient obtained by dividing $.644 by the lowest closing bid price of our
common stock during the ten consecutive trading days immediately preceding each
conversion date multiplied by 1.2 on the first date the additional shares are
issued and 1.22 on the second date the additional shares are issued multiplied
by the number of shares issuable on conversion of the notes.

         DELIVERY DEFAULTS. We will commit a delivery default if we do not
deliver the shares issuable on conversion of the notes and the additional
shares to the note holders within four business days after we receive proper
notice from the note holders. If we commit a delivery default we must pay each
note holder up to $2,500 in cash for each day we do not deliver the shares
issuable on conversion of the notes or the additional shares. Any late fee may,
at the note holders' option, be added to the principal amount of the notes.

         If we commit a delivery default because we do not have enough
authorized but unissued shares of our common stock to deliver to the note
holders, we must issue the note holders all of the shares of our common stock
which are then available. The conversion price for the shares we were unable to
deliver will be adjusted to the lower of the conversion price on the date we
commit the delivery default or the conversion price on the conversion date. The
number of additional shares issuable will also be adjusted based on the date
our shares of common stock are actually delivered. In addition to the late fee,
we must also make cash payments to the note holders based on the number of days
the delivery default exists. At the note holders' option, the


                                      15
<PAGE>   18

additional payments for each calendar month are payable in cash or convertible
into our common stock at the conversion price for the notes then in effect. In
the event the note holder elects to take such payment in common stock, the
holder may convert payment amount into common stock at the conversion price in
effect at the time of conversion.

         RESTRICTION. As long as the notes are outstanding, we may not pay any
dividend, redeem any of our outstanding securities, assume any liability for
borrowed money, lend money or guarantee any obligations, incur any obligations
senior to the notes, sell or lease assets, except in the ordinary course of
business, without the prior written consent of the note holders.

         DEFAULT. If we default on our obligations under the purchase agreement
or the notes, the note holders may require us to immediately pay no less than,
and possibly more than, 130% of the principal balance, the accrued interest and
any other sums due the note holders under the notes. If we fail to make the
payment within five business days of written notice that the payment is due,
the note holders may, in lieu of the payment, require us to immediately issue a
number of shares of our common stock equal to the default payment amount
divided by the conversion price for the notes then in effect.

THE WARRANTS

         The warrants entitle Isosceles and Cefeo to purchase an aggregate of
932,039 shares of our common stock. The warrants are exercisable until March 17,
2004. The warrants are exercisable at the lower of $.50 or the lowest closing
bid price of our common stock during the ten consecutive trade days immediately
preceding the conversion date on the 31st and 61st days after the date the first
one half of the notes converts. The warrants also contain a cashless exercise
provision.

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

REGISTRATION RIGHTS

         The registration rights agreement we entered into with Isosceles and
Cefeo required us to pay Isosceles and Cefeo a fee if any of the following
events occur:

         -        We fail to have a registration statement registering the
shares of common stock issuable on the exercise or conversion of the notes and
warrants effective on or before July 7, 1999;


                                      16
<PAGE>   19

         -        We fail to maintain the effectiveness of the registration
statement registering such shares; or

         -        Our common stock is de-listed from trading on NASDAQ.

         The amount of the fee for each separate default is two percent (2%) of
the principal amount of the notes converted plus the exercise price paid for
warrants exercised plus the principal amount of outstanding unconverted notes.

         We are also obligated to redeem for cash all notes, warrants and
common stock issued upon exercise or conversion of either, if beginning
September 13, 1999, the registration statement ceases to be effective for a
period of 30 consecutive business days or 60 business days during any 12 month
period. The redemption price is equal to the greater of:

         -        the number of shares of our common stock the notes and
warrants issuable upon conversion to the selling security holders multiplied by
the high trade price of our common stock on the day we receive redemption
notice from the selling security holders; or

         -        115% of the principal amount of the notes, the aggregate
exercise price paid for the exercise of the warrants plus any other fees
described above owed to the selling security holder.

ADDITIONAL WARRANTS

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

         The following table sets forth as of March 17, 1999 (1) the name of
the selling security holders, (2) the amount of common stock held directly or
indirectly or underlying the notes and the warrants to be offered by the
selling security holders and (3) the amount to be owned by the selling security
holders following the sale of such shares. As of March 17, 1999, there were
outstanding 64,995,402 shares of Viragen's common stock.

offer, sale and delivery of the shares of our common stock. These include, all
expenses and fees of preparing, filing and printing the registration statement
and mailing of these items. Viragen will not pay selling commissions and
expenses for any sales by the selling security holders. Viragen will indemnify
the selling security holders against civil liabilities including liabilities
under the Securities Act of 1933, as amended.

                              PLAN OF DISTRIBUTION

         These shares of our common stock may be sold by the selling security
holders, or by other successors in interest. The sales may be made on one or
more exchanges or in the over-the-counter market including the Nasdaq National
Market of The Nasdaq Stock Market, or at prices related to the then current
market price, or in negotiated transactions.

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

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


                                      18
<PAGE>   21

         (2) purchases by a broker or dealer as principal and resale by such
broker or dealer;

         (3) ordinary brokerage transactions and transactions in which the
broker solicits purchasers; and

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

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

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

                           DESCRIPTION OF SECURITIES

         Viragen is currently authorized to issue up to 75,000,000 shares of
common stock, par value $.01 per share, of which 65,605,012 shares were
outstanding as of March 31, 1999. Viragen is also authorized to issue up to
1,000,000 shares of preferred stock, par value $1.00 per share, of which 2,650
shares of Series A Preferred Stock and 11 shares of Series I Preferred Stock
were outstanding as of March 31, 1999.

COMMON STOCK

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


                                      19
<PAGE>   22

         Each share of our common stock has one vote. Holders of our common
stock do not have cumulative voting rights, which means that the holders of a
plurality of the shares voting for the election of directors can elect all of
the directors. In that event, the holders of the remaining shares will not be
able to elect any directors. Viragen's By-Laws provide that a majority of the
issued and outstanding shares of our common stock are a quorum to transact
business at a stockholders' meeting. Our common stock has no preemptive,
subscription or conversion rights and is not redeemable.

PREFERRED STOCK

         Viragen is authorized to issue a total of 1,000,000 shares of
preferred stock, par value $1.00 per share. The preferred stock may be issued
by resolutions of Viragen's Board of Directors without any action of the
stockholders. However, any issuance of 20% or more of Viragen's common stock
will require stockholder approval under Nasdaq Rule 4460(i)(1)(D)(ii). These
resolutions may authorize issuances of such preferred stock in one or more
series. In addition, they may fix and determine dividend and liquidation
preferences, voting rights, conversion privileges, redemption terms and other
privileges and rights of the shares of each authorized series.

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

         SERIES A PREFERRED STOCK

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

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

         Owners of the Series A Preferred Stock are entitled to receive $10.00
per share, plus accrued and unpaid dividends, upon liquidation, dissolution or
winding up of Viragen before any


                                      20
<PAGE>   23

distribution or payment is made to holders of the common stock or other stock
of Viragen junior to the Series A Preferred Stock.

         SERIES I PREFERRED STOCK

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

         The Series I Preferred Stock and the 8% accretion factor is
convertible into shares of our common stock at the lower of:

         (1)      $1.59; or

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

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

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

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

                            OVER-THE-COUNTER MARKET

         Viragen's common stock is traded in the Nasdaq National Market under
the symbol "VRGN." If for any reason Viragen does not maintain the requirements
for inclusion of our common stock on Nasdaq, then our common stock would
continue to be traded in the over-the-counter market through the "pink sheets"
or the NASD's OTC Bulletin Board. In the event our


                                      21
<PAGE>   24

common stock would be covered by a Securities and Exchange Commission rule that
imposes additional sales practice requirements on broker-dealers who sell such
securities to persons other than established customers and accredited
investors, generally institutions with assets in excess of $5,000,000 or
individuals with net worth in excess of $1,000,000 or annual income exceeding
$200,000 or $300,000 jointly with their spouse. For transactions covered by the
rule, the broker-dealer must make a special suitability determination for the
purchaser and receive the purchaser's written agreement to the transaction
prior to the sale. Consequently, the rule may affect the ability of
broker-dealers to sell Viragen's securities. It also may affect the ability of
purchasers in this offering to sell their shares in the secondary market. See
the section of this prospectus entitled "High Risk Factors" and the subheading
"Possible Delisting from Nasdaq and Penny Stock Rules" for more information on
the topics discussed above.

                                INDEMNIFICATION

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

         A corporation may indemnify against expenses, including attorney's
fees, and, except for an action by or in the name of the corporation, against
judgments, fines and amounts paid in settlement as part of such suit or
proceeding. This applies only if the person indemnified acted in good faith and


                                      22
<PAGE>   25

in a manner he or she reasonably believed to be in the best interest of the
corporation. In addition, with respect to any criminal action or proceeding,
the person had no reasonable cause to believe his or her conduct was unlawful.

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

         Section 145 of the General Corporation Law of Delaware further
provides that if a director, officer, employee or agent of the corporation has
been successful in the defense of any suit, claim or proceeding described
above, he or she will be indemnified for expenses, including attorneys' fees,
actually and reasonably incurred by him or her.

         Insofar as indemnification for liabilities arising under the Act is
permitted as to directors, officers and controlling persons of Viragen, in the
opinion of the Securities and Exchange Commission, such indemnification is
against public policy and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities, other than the payment by
Viragen in the successful defense of any action, suit or proceeding, is
asserted, Viragen will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy. Viragen will be governed by the final adjudication of such issue.

Item 15.          Indemnification of Directors and Officers.

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

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

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

         Section 145 of the General Corporation Law of Delaware further
provides that if a director, officer, employee or agent of the corporation has
been successful in the defense of any suit, claim or proceeding described
above, he or she will be indemnified for expenses, including attorneys' fees,
actually and reasonably incurred by him or her.

Item 17. UNDERTAKINGS.

         (a)      The undersigned Company hereby undertakes:

                           (i)      to file, during any period in which it
offers or sells securities, a post-effective amendment to this Registration
Statement to include any additional or changed material information on the plan
of distribution;

                           (ii)     that, for determining any liability under
the Securities Act, treat each such post-effective amendment as a new
Registration Statement of the securities offered at that time shall be deemed
to be the initial bona fide offering thereof;

                           (iii)    to file a post-effective amendment to remove
from registration any of the securities that remain unsold at the end of the
offering; and


                                     II-11
<PAGE>   37

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

                  (b)      The undersigned Registrant hereby undertakes that,
for purposes of determining any liability under the Securities Act of 1933,
each filing of the Registrant's Annual Report pursuant to Section 13(a) or
15(d) of the Securities Exchange Act of 1934 that is incorporated by reference
in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

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

         RE: REGISTRATION STATEMENT ON FORM S-3; VIRAGEN, INC. (THE "COMPANY"),
             11,000,000 SHARES OF COMMON STOCK

Gentlemen:

         This opinion is submitted pursuant to the applicable rules of the
Securities and Exchange Commission with respect to the registration by the
Company of an aggregate of 11,00,000 shares of Common Stock, par value $.01 per
share (the "Common Stock"), to be sold by The Isosceles Fund Limited and Cefeo
Investments Limited (the "Subscribers") and Ballsbridge Finance, Limited, Elliot
Layne & Associates, Inc. and Ven-Gua Capital Markets Ltd. (the "Finders") as
designated in the Registration Statement. The shares of Common Stock to be sold
consist of up to (i) 9,912,622 shares of Common Stock (the "Note Shares")
issuable to the Subscriber upon the conversion of the 8% Redeemable Promissory
notes (the "Notes") as set forth in the Purchase Agreement between the Company
and the Subscribers dated March 17, 1999 (the "Purchase Agreement"); (ii)
932,039 shares of Common Stock issuable upon the exercise of common stock
purchase warrants issuable to the Subscriber pursuant to the Purchase Agreement
(the "Warrants"); (iii) 155,379 shares of Common Stock (the "Finder Shares")
issuable to the Finders, for the transactions contemplated in the Purchase
Agreement, upon the exercise of Common Stock purchase warrants (the "Finders'
Warrants").

         In our capacity as counsel to the Company, we have examined the
original, certified, conformed, photostat or other copies of the Company's
Certificate of Incorporation (as Amended), By-Laws, the Purchase Agreement and
documents pertaining to the Purchase Agreement, and exhibits and corporate
minutes provided to us

by the Company. In all such examinations, we have assumed the genuineness of all
signatures on original documents, and the conformity to originals or certified
documents of all copies submitted to us as conformed, photostat or other copies.
In passing upon certain corporate records and documents of the Company, we have
necessarily assumed the correctness and completeness of the statements made or
included therein by the Company, and we express no opinion thereon.

         Based upon and in reliance of the foregoing, we are of the opinion that
the Common Stock to be issued to the Subscribers and the Finders in accordance
with the Purchase Agreement and the Notes and upon the exercise of the Warrants
and Finders' Warrants (assuming payment of the respective exercise prices
therefor), when issued in accordance with the terms of the Purchase Agreement,
the Notes, the Warrants and the Finders' Warrants will be validly issued, fully
paid and non-assessable.

         We hereby consent to the use of this opinion in Amendment No. 1 to the
Registration Statement on Form S-3 to be filed with the Commission.

                            Very truly yours,

                            ATLAS, PEARLMAN, TROP & BORKSON, P.A.

Subsidiaries are held by them under valid, subsisting and enforceable leases
with such exceptions as would not have a Material Adverse Effect.

         Section 5.29 INSURANCE. The Company and each of its Subsidiaries are
insured by insurers of recognized financial responsibility against such losses
and risks and in such mounts as management of the Company believes to be prudent
and customary in the businesses in which the Company and its Subsidiaries are
engaged. Neither the Company nor any such Subsidiary has any reason to believe
that it will not be able to renew its existing insurance coverage as and when
such coverage expires or to obtain similar coverage from similar insurers as may
be necessary to continue its business at a cost that would not have a Material
Adverse Effect.

         Section 5.30 INTERNAL ACCOUNTING CONTROLS. The Company and each of its
Subsidiaries maintain a system of internal accounting controls sufficient, in
the judgment of the Company's board of directors, to provide reasonable
assurance that (i) transactions are executed in accordance with management's
general or specific authorizations, (ii) transactions are recorded as necessary
to permit preparation of financial statements in conformity with generally
accepted accounting principles and to maintain asset accountability, (iii)
access to assets is permitted only in accordance with management's general or
specific authorization and (iv) the recorded accountability for assets is
compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences.

         Section 5.31 FOREIGN CORRUPT PRACTICES. Neither the Company, nor any of
its Subsidiaries, nor any director, officer, agent, employee or other person
acting on behalf of the Company or any Subsidiary has, in the course of his
actions for, or on behalf of, the Company, used any corporate funds for any
unlawful contribution, gift, entertainment or other unlawful expenses relating
to political activity; made any direct or indirect unlawful payment to any
foreign or domestic government official or employee from corporate funds;
violated or is in violation of any provision of the U.S. Foreign Corrupt
Practices Act of 1977; or made any bribe, rebate, payoff, influence payment,
kickback or other unlawful payment to any foreign or domestic government
official or employee.

         Section 5.32 SOLVENCY. The Company (both before and after giving effect
to the transactions contemplated by this Agreement) is solvent (I.E., its assets
have a fair market value in excess of the amount required to pay its probable
liabilities on its existing debts as they become absolute and matured) and
currently the Company has no information that would lead it to reasonably
conclude that the Company would not have the ability to, nor does it intend to
take any action that would impair its ability to, pay its debts from time to
time incurred in connection therewith as such debts mature. The Company did not
receive a qualified opinion from its auditors with respect to its most recent
fiscal year end and does not anticipate or know of any basis upon which its
auditors might issue a qualified opinion in respect




                                       12
<PAGE>   13

of its current fiscal year, assuming the Company received the financing
necessary to sustain operations for the forthcoming financial year.

                            COVENANTS OF THE COMPANY

         Section 6.1 REGISTRATION RIGHTS. The Company shall cause the
Registration Rights Agreement to remain in full force and effect and the Company
shall comply in all respects with the terms thereof.

         Section 6.2 REGISTRATION OF COMMON STOCK. The Company shall maintain

shall file a registration with the SEC on Form S-3 registering for resale the
shares of the Company's Common Stock underlying the applicable Notes and
Warrants and the Re-Set Shares (collectively, the "Registered Shares"), as
described in the Registration Rights Agreement. The Company further shall, if
the Company applies to have the Common Stock traded on any other Principal
Market, include in such application the Registered Shares, and shall take such
other action as is necessary or desirable in the opinion of the Subscribers to
cause the Common Stock to be listed on such other Principal Market as promptly
as possible. The Company shall take all action necessary to continue the listing
and trading of its Common Stock on the Principal Market (including, without
limitation, maintaining sufficient net tangible assets) and will comply in all
respects with the Company's reporting, filing and other obligations under the
bylaws or rules of the NASD and the Principal Market.

         Section 6.3 EXCHANGE ACT REGISTRATION. The Company shall cause its
Common Stock to continue to be registered under Section 12(g) or 12(b) of the

(whether or not permitted by said Act or the rules thereunder) to terminate or
suspend such registration or to terminate or suspend its reporting and filing
obligations under said Act. The Company will take all action to continue the
listing and trading of its Common Stock on the Principal Market and will comply
in all respects with the Company's reporting, filing and other obligations under
the bylaws or rules of the NASD and the Principal Market.

         Section 6.4 LEGENDS. The certificates evidencing the Registered Shares
to be sold by the Subscribers pursuant to Section 2 shall be free of legends,
except as set forth in Article IX.

         Section 6.5 CORPORATE EXISTENCE. The Company will take all steps
necessary to preserve and continue the corporate existence of the Company.

         Section 6.6 ADDITIONAL SEC DOCUMENTS; OTHER DOCUMENTS. The Company will
deliver to the Subscribers, and when the originals thereof are submitted to the
SEC for filing, copies of all SEC Documents so furnished or submitted to the
SEC. The Company will further deliver copies of all press releases issued by the
Company and all communications to shareholders to the Subscribers.

         Section 6.7 REGISTRATION STATEMENT. (a) The Company will immediately
notify the Subscribers upon the occurrence of any of the following events in
respect of a Registration Statement or related prospectus in respect of an
offering of Registrable Securities; (i) receipt of any request for additional
information by the SEC or any other federal or state governmental authority
during the period




                                       13
<PAGE>   14

of effectiveness of the Registration Statement, or for amendments or supplements
to the Registration Statement or related prospectus; (ii) the issuance by the
SEC or any other federal or state governmental authority of any stop order
suspending the effectiveness of the Registration Statement or the initiation of
any proceedings for that purpose; (iii) receipt of any notification with respect
to the suspension of the qualification or exemption from qualification of any of
the Registrable Securities for sale in any jurisdiction or the initiation or
threatening of any proceeding for such purpose; (iv) the happening of any event
that makes any statement made in such Registration Statement or related
prospectus or any document incorporated or deemed to be incorporated therein by
reference untrue in any material respect or that requires the making of any
changes in the Registration Statement, related prospectus or documents so that,
in the case of the Registration Statement, it will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading, and
that in the case of the related prospectus, it will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; and (v) the Company's
reasonable determination that a post-effective amendment to the registration
statement would be appropriate; and the Company will promptly make available to
the Subscribers any such supplement or amendment to the related prospectus.

         Section 6.8 CONSOLIDATION; MERGER. The Company shall not, at any time
after the date hereof, effect any merger or consolidation of the Company with or
into, or a transfer of all or substantially all of the assets of the Company to,
another entity (a "Consolidation Event") unless the resulting successor or
acquiring entity (if not the Company) (a) assumes by written instrument the
obligation to deliver to the Subscribers such shares of Common Stock as the
Subscribers are entitled to receive pursuant to this Agreement and (b) is an
SEC-registered company whose common stock is listed on NASDAQ, AMEX or NYSE.

         Section 6.9 NOTES AND WARRANTS. The sale and issuance of the Notes and
Warrants shall be made in accordance with the provisions and requirements of
Regulation D and any applicable state law.

         Section 6.10 RESERVATION OF SHARES. The Company shall at all times have
authorized, and reserved for the purpose of issuance, a sufficient number of
shares of Common Stock to provide for the full conversion or exercise of the
outstanding Notes and Warrants and issuance of the Conversion Shares and Warrant
Shares in connection therewith (based on the Conversion Price of the Notes or
Exercise Price of the Warrants in effect from time to time). The Company shall
not reduce the number of shares of Common Stock reserved for issuance upon
conversion of Notes and exercise of the Warrants without the consent of the
Subscribers. The Company shall use its best efforts at all times to maintain the
number of shares of Common Stock so reserved for issuance at no less than 300%
of the number that is then actually issuable upon full conversion of the Notes
and 150% of the number issuable upon exercise of the Warrants (based on the
Conversion Price of the Notes or Exercise Price of the Warrants in effect from
time to time). If at any time the number of shares of Common Stock authorized
and reserved for issuance is below the number of Conversion Shares and Warrant
Shares issued and issuable upon conversion of the Notes and exercise of the
Warrants (based on the Conversion Price of the Notes or Exercise Price of the
Warrants then in effect), the Company will promptly take all corporate action
necessary to authorize and reserve a sufficient number of shares, including,
without limitation, calling a special meeting of shareholders to authorize
additional shares to meet the Company's obligations under this Section 6.10, in
the case of an insufficient number of authorized shares, and using its best
efforts to obtain shareholder approval of an increase in such authorized number
of shares.

         Section 6.11 NO INTEGRATION. The Company shall not make any offers or
sales of any other security under circumstances that would require registration
of the offer and sale of Notes and Warrants under the Securities Act or cause
such offering to be integrated with any other offering of securities by the
Company for the purpose of any stockholder approval provision applicable to the
Company or its securities.

         Section 6.12 LEGAL OPINION ON SUBSCRIPTION DATE. The Company's
independent counsel shall deliver to the Subscribers on the Subscription Date an
opinion substantially in the form of Exhibit C.

                   Agreement to be performed, satisfied or complied with by the
                   Subscriber at or prior to closing.

                   (c) The Company shall, prior to the Initial Closing Date,
                   disclose to the Subscribers the amount outstanding under its
                   Series H and I Preferred Stock and take such action with

                   authorizing a reverse stock split of at least 4:1 (provided

                   dated December 16, 1998 are met or withdrawn).

                   (e) Senior management of the Company and other shareholders,
                   constituting approximately 15% or more of the holders of the
                   Company's voting shares, shall have executed a letter

                   (g) The Subscribers shall have received a Certificate in the
                   form of Exhibit D hereto.

                   (h) The Company shall have notified the transfer agent of the
                   terms of this agreement, including each Conversion Date,
                   Re-Set Date and the deadline for filing of the Registration
                   Statement and the Effective Date. The Company shall instruct

                   certificates without restrictive legend in the name of the
                   Subscribers or such persons as may be designated by the
                   Subscribers representing the number of shares of the Issuer's
                   common stock issuable upon each respective Conversion Date,
                   Re-Set Date and Warrant Exercise Date, as applicable, and

                   the respective Conversion Date, Re-Set Date and Warrant
                   Exercise Date. The Issuer represents that instructions to

                   with respect to the share certificates until the Effective
                   Date and that thereafter the Issuer's common stock shall
                   otherwise be freely transferable on the books and records of
                   the Issuer. Prior to the Purchase Date the Issuer will cause
                   the transfer agent to execute and acknowledge in writing to
                   the Subscribers an irrevocable consent to the foregoing (the
                   "Transfer Agent Consent") in the form set out in Exhibit E
                   hereto. To the extent set forth in the terms of the Note,
                   delivery shall be electronically and the Company shall so
                   instruct the transfer agent.

         DUE DILIGENCE REVIEW; NON-DISCLOSURE OF NON-PUBLIC INFORMATION

         Section 8.1 DUE DILIGENCE REVIEW. The Company shall make available for

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 Subscribers 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.

         Section 8.2 NON-DISCLOSURE OF NON-PUBLIC INFORMATION. Each of the

representatives with the opportunity to accept or refuse to accept such
non-public information for review.

         Section 12.2 INDEMNIFICATION. The Company agrees to indemnify and hold
harmless each Subscriber, its partners, affiliates, officers, directors,
employees, and duly authorized agents, and each Person or entity, if any, who
controls the Subscriber within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act, together with the Controlling Persons (as
defined in the Registration Rights Agreement) from and against any Damages,
joint or several, and any action in respect thereof to which the Subscriber, its
partners, affiliates, officers, directors, employees, and duly authorized
agents, and any such Controlling Person becomes subject to, resulting from,
arising out of or relating to any misrepresentation, breach of warranty or
nonfulfillment of or failure to perform any covenant or agreement on the part of
Company contained in this Agreement.

         Section 12.3 METHOD OF ASSERTING INDEMNIFICATION CLAIMS. All claims for
indemnification by any Indemnified Party (as defined below) under Section 13.2
will be asserted and resolved as follows:

                  (a) In the event any claim or demand in respect of which any
                  person claiming indemnification under any provision of Section
                  13.2 (an "Indemnified Party") might seek indemnity under
                  Section 13.2 is asserted against or sought to be collected
                  from such Indemnified Party by a person other than the
                  Company, the Subscriber or any affiliate of the Company or (a
                  "Third Party Claim"), the Indemnified Party shall deliver a
                  written notification, enclosing a copy of all papers served,
                  if any, and specifying the nature of and basis for such Third
                  Party Claim and for the Indemnified Party's claim for
                  indemnification that is being asserted under any provision of
                  Section 13.2 against any person (the "Indemnifying Party"),
                  together with the amount or, if not then reasonably
                  ascertainable, the estimated amount, determined in good faith,
                  of such Third Party Claim (a "Claim Notice") with reasonable
                  promptness to the Indemnifying Party. If the Indemnified Party
                  fails to provide the Claim Notice with reasonable promptness
                  after the Indemnified Party receives notice of such Third
                  Party Claim, the Indemnifying Party will not be obligated to
                  indemnify the Indemnified Party with respect to such Third
                  Party Claim to the extent that the Indemnifying Party's
                  ability to defend has been irreparably prejudiced by such
                  failure of the Indemnified Party. The Indemnifying Party will
                  notify the Indemnified Party as soon as practicable within the
                  period ending 30 calendar days following receipt by the
                  Indemnifying Party of either a Claim Notice or an Indemnity
                  Notice (as defined below) (the "Dispute Period") whether the
                  Indemnifying Party disputes its liability or the amount of its
                  liability to the Indemnified Party under Section 12.2 and
                  whether the Indemnifying Party desires, at its sole cost and
                  expense, to defend the Indemnified Party against such Third
                  Party Claim.

                            (i) If the Indemnifying Party notifies the
                            Indemnified Party within the Dispute Period that the
                            Indemnifying Party desires to defend the Indemnified
                            Party with respect to the Third Party Claim pursuant
                            to this Section 13.3(a), then the Indemnifying Party
                            will have the right to defend, with counsel
                            reasonably satisfactory to the Indemnified Party, at
                            the sole cost and expense of the Indemnifying Party,
                            such Third Party Claim by all appropriate
                            proceedings, which proceedings will be vigorously
                            and diligently prosecuted by the Indemnifying Party
                            to a final conclusion or will be settled at the
                            discretion of the Indemnifying Party (but only with
                            the consent of the Indemnified Party in the case of
                            any settlement that provides for any relief other
                            than the payment of




                                       20
<PAGE>   21

                            monetary damages or that provides for the payment of
                            monetary damages as to which the Indemnified Party
                            will not be indemnified in full pursuant to Section
                            13.2). The Indemnifying Party will have full control
                            of such defense and proceedings, including any
                            compromise or settlement thereof; PROVIDED, HOWEVER,
                            that the Indemnified Party may, at the sole cost and
                            expense of the Indemnified Party, at any time prior
                            to the Indemnifying Party's delivery of the notice
                            referred to in the first sentence of this clause
                            (i), file any motion, answer or other pleadings or
                            take any other action that the Indemnified Party
                            reasonably believes to be necessary or appropriate
                            to protect its interests; and provided further, that
                            if requested by the Indemnifying Party, the
                            Indemnified Party will, at the sole cost and expense
                            of the Indemnifying Party, provide reasonable
                            cooperation to the Indemnifying Party in contesting
                            any Third Party Claim that the Indemnifying Party
                            elects to contest. The Indemnified Party may
                            participate in, but not control, any defense or
                            settlement of any Third Party Claim controlled by
                            the Indemnifying Party pursuant to this clause (i),
                            and except as provided in the preceding sentence,
                            the Indemnified Party will bear its own costs and
                            expenses with respect to such participation.
                            Notwithstanding the foregoing, the Indemnified Party
                            may take over the control of the defense or
                            settlement of a Third Party Claim at any time if it
                            irrevocably waives its right to indemnity under
                            Section 12.2 with respect to such Third Party Claim.

                            (ii) If the Indemnifying Party fails to notify the
                            Indemnified Party within the Dispute Period that the
                            Indemnifying Party desires to defend the Third Party
                            Claim pursuant to Section 13.3(a), or if the
                            Indemnifying Party gives such notice but fails to
                            prosecute vigorously and diligently or settle the
                            Third Party Claim, or if the Indemnifying Party
                            fails to give any notice whatsoever within the
                            Dispute Period, then the Indemnified Party will have
                            the right to defend, at the sole cost and expense of
                            the Indemnifying Party, the Third Party Claim by all
                            appropriate proceedings, which proceedings will be
                            prosecuted by the Indemnified Party in a reasonable
                            manner and in good faith or will be settled at the
                            discretion of the Indemnified Party (with the
                            consent of the Indemnifying Party, which consent
                            will not be unreasonably withheld). The Indemnified
                            Party will have full control of such defense and
                            proceedings, including any compromise or settlement
                            thereof; provided, however, that if requested by the
                            Indemnified Party, the Indemnifying Party will, at
                            the sole cost and expense of the Indemnifying Party,
                            provide reasonable cooperation to the Indemnified
                            Party and its counsel in contesting any Third Party
                            Claim which the Indemnified Party is contesting.
                            Notwithstanding the foregoing provisions of this
                            clause (ii), if the Indemnifying Party has notified
                            the Indemnified Party within the Dispute Period that
                            the Indemnifying Party disputes its liability or the
                            amount of its liability hereunder to the Indemnified
                            Party with respect to such Third Party Claim and if
                            such dispute is resolved in favor of the
                            Indemnifying Party in the manner provided in clause
                            (iii) below, the Indemnifying Party will not be
                            required to bear the costs and expenses of the
                            Indemnified Party's defense pursuant to this clause
                            (ii) or of the Indemnifying Party's participation
                            therein at the Indemnified Party's request, and the
                            Indemnified Party will reimburse the Indemnifying
                            Party in full for all reasonable costs and expenses
                            incurred by the Indemnifying Party in connection
                            with such litigation. The Indemnifying Party may
                            participate in, but not control, any defense or
                            settlement controlled by the





                                       21
<PAGE>   22

                            Indemnified Party pursuant to this clause (ii), and
                            the Indemnifying Party will bear its own costs and
                            expenses with respect to such participation.

                            (iii) If the Indemnifying Party notifies the
                            Indemnified Party that it does not dispute its
                            liability or the amount of its liability to the
                            Indemnified Party with respect to the Third Party
                            Claim under Section 13.2 or fails to notify the
                            Indemnified Party within the Dispute Period whether
                            the Indemnifying Party disputes its liability or the
                            amount of its liability to the Indemnified Party
                            with respect to such Third Party Claim, the Loss in
                            the amount specified in the Claim Notice will be
                            conclusively deemed a liability of the Indemnifying
                            Party under Section 13.2 and the Indemnifying Party
                            shall pay the amount of such Loss to the Indemnified
                            Party on demand. If the Indemnifying Party has
                            timely disputed its liability or the amount of its
                            liability with respect to such claim, the
                            Indemnifying Party and the Indemnified Party will
                            proceed in good faith to negotiate a resolution of
                            such dispute, and if not resolved through
                            negotiations within the Resolution Period, such
                            dispute shall be resolved by arbitration in
                            accordance with paragraph (c) of this Section 13.3.

                  (b) In the event any Indemnified Party should have a claim
                  under Section 13.2 against the Indemnifying Party that does
                  not involve a Third Party Claim, the Indemnified Party shall
                  deliver a written notification of a claim for indemnity under
                  Section 13.2 specifying the nature of and basis for such
                  claim, together with the amount or, if not then reasonably
                  ascertainable, the estimated amount, determined in good faith,
                  of such claim (an "Indemnity Notice") with reasonable
                  promptness to the Indemnifying Party. The failure by any
                  Indemnified Party to give the Indemnity Notice shall not
                  impair such party's rights hereunder except to the extent that
                  the Indemnifying Party demonstrates that it has been
                  irreparably prejudiced thereby. If the Indemnifying Party
                  notifies the Indemnified Party that it does not dispute the
                  claim or the amount of the claim described in such Indemnity
                  Notice or fails to notify the Indemnified Party within the
                  Dispute Period whether the Indemnifying Party disputes the
                  claim or the amount of the claim described in such Indemnity
                  Notice, the Loss in the amount specified in the Indemnity
                  Notice will be conclusively deemed a liability of the
                  Indemnifying Party under Section 13.2 and the Indemnifying
                  Party shall pay the amount of such Loss to the Indemnified
                  Party on demand. If the Indemnifying Party has timely disputed
                  its liability or the amount of its liability with respect to
                  such claim, the Indemnifying Party and the Indemnified Party
                  will proceed in good faith to negotiate a resolution of such
                  dispute, and if not resolved through negotiations within the
                  Resolution Period, such dispute shall be resolved by
                  arbitration in accordance with paragraph (c) of this Section
                  13.3.

                  (c) Any dispute under this Agreement (including, without
                  limitation, in connection with this Section 13.3) or the
                  Registration Rights Agreement shall be submitted to
                  arbitration and shall be finally and conclusively determined
                  by the decision of a single arbitrator who shall have
                  experience in civil litigation involving interpretation of
                  stock purchase agreements (the "Arbitrator"). The arbitration
                  shall be governed by the United States Arbitration Act, 9
                  U.S.C. Sections 1-16, 201-208 and judgment upon the award
                  rendered by the Arbitrator may be entered by any United States
                  federal or state court in and of the State of New York, to the
                  non-exclusive jurisdiction of which each of the parties hereto
                  irrevocably submits. The parties agree to cooperate and use
                  their reasonable best efforts to cause the Arbitrator render a
                  decision in any dispute within 30 days following the





                                       22
<PAGE>   23

                  commencement of proceedings with respect thereto and, to the
                  extent practicable, the decision of the Arbitrator shall be
                  rendered no more than 30 calendar days following such
                  commencement. The Arbitrator shall cause its written decision
                  to be delivered to the Indemnified Party and the Indemnifying
                  Party within 3 business days following such decision. Any
                  decision made by the Arbitrator (either prior to or after the
                  expiration of such 30 calendar-day period) shall be final,
                  binding and conclusive on the Indemnified Party and the
                  Indemnifying Party and shall be entitled to be enforced to the
                  fullest extent permitted by law and entered in any court of
                  competent jurisdiction. Each party to any arbitration shall
                  bear its own expense in relation thereto, including but not
                  limited to such party's attorneys' fees, if any, and the
                  expenses and fees of the Arbitrator shall be divided between
                  the Indemnifying Party and the Indemnified Party in the same
                  proportion as the portion of the related claim determined by
                  the Arbitrator to be payable to the Indemnified Party bears to
                  the portion of such claim determined not to be so payable.

the parties actually executing such counterparts and all of which together shall
constitute one and the same instrument.

         Section 13.3 ENTIRE AGREEMENT. This Agreement, the Exhibits hereto and
the Registration Rights Agreement set forth the entire agreement and

declared by a court of competent jurisdiction to be illegal, unenforceable or
void, this Agreement shall continue in full force and effect without said
provision; provided that such severability shall be ineffective if it materially
changes the economic benefit of this Agreement to any party.

         Section 13.5 TITLES AND SUBTITLES. The titles and subtitles used in
this Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

              FORM OF OPINION OF THE COMPANY'S INDEPENDENT COUNSEL

         1. The Company is duly organized and validly existing under the laws of
the state of Delaware and has requisite power and authority to enter into the
Purchase Agreement, the Registration Rights Agreement, the Notes, the Warrants
and the Escrow Agreement (the "Agreements"); the execution and delivery of the
Agreements and the consummation by the Company of the transactions contemplated
thereby are duly authorized by all necessary corporate action and no further
consent or authorization of the Company or its Board of Directors or
Shareholders is required; and the Agreements have been duly executed and
delivered by the Company and constitute valid and binding obligations of the
Company enforceable against the Company in accordance with their terms, except
as such enforceability may be limited by applicable bankruptcy, insolvency or
similar laws relating to, or affecting generally the enforcement of, creditors'
rights and remedies or by other equitable principles of general application.

         2. The Shares of Common Stock to be received upon exercise of the
Warrants or conversion of the Notes or issuance of the Re-Set Shares are validly
issued and outstanding, fully paid and non-assessable and subject to no
preemptive rights.

         3. The number of authorized shares of the Company (75,000,000) will be
unaffected by a reverse stock split.

         4. The sale of the Notes and the Warrants and the conversion or
exercise thereof is not required to be registered under the Securities Act of
1933.
