                     AMENDMENT TO 8% SECURED PROMISSORY NOTE

      This Amendment to 8% Secured Promissory Note (the "Note") is made this
22nd day of November, 2002 by and between VlRAGEN, INC. ("Viragen") and
ISOSCELES FUND LTD. {"lsosceles"):

      WHEREAS, Viragen has issued its full recourse 8% Secured Promissory Note
to Isosceles secured by 2,500,000 shares of common stock of Viragen and which
provides for certain registration rights under the Securities Act of 1933 with
respect to such underlying shares of common stock; and

      WHEREAS, the parties desire to modify the terms of the Note as hereinafter
provided:

      THEREFORE, the parties hereby agree to the following modifications of the
Note:

      1.    The Note shall not have a fixed maturity date and shall be payable
within three (3) business days of demand by the noteholder.

      2.    The Note shall be convertible in whole or in part at a conversion
price of $0.175 per share, subject to adjustments as set forth in that
Securities Purchase Agreement and related 5% Secured Convertible Debenture dated
November 8, 2002. Interest on the Note shall be payable in cash or common stock
of Viragen, in whole or in part, in the sole option of Isosceles at the
applicable conversion price of the Note.

      3.    During the period that the Note is outstanding, Isosceles shall have
the same Note conversion and Warrant exercise prices as do the investors for the
above Securities Purchase Agreement. In addition, Isosceles shall have the
benefit of anti-dilution protection on a weighted basis in the event of any
issuances of capital stock or derivative securities involving the issuance of
capital stock at below the conversion price to other parties. The intention of
this anti-dilution provision is that Isosceles shall have the same conversion
price on the Note and exercise price for the Warrants that the investors for the
Securities Purchase Agreement referred to above have irregardless of a weighted
calculation, and would have the benefit of anti-dilution protection on a
weighted basis in the event of any issuances of capital stock or derivative
securities attributable to issuance of securities to other investors during the
time that the Notes and Warrants are outstanding.

      4.    Viragen agrees to register the 2,500,000 shares of its common stock
presently in escrow with Adorno & Yoss, P.A. pursuant to the Note and such
additional shares to cover common stock underlying the Note (including interest
thereon), at its own cost, within 30 days of the date hereof and to process such
registration statement in an expeditious manner. Isosceles shall have the same
protections as afforded to the investors in the above Securities Purchase
Agreement under the Registration Rights Agreement provided to such investors.
<PAGE>
      5.    In the event that Isosceles does not elect to convert the entire
principal amount due under its 8% Secured Promissory Note within 90 days of the
date of this Amendment and in consideration for the execution of this Amendment,
Viragen shall issue to Isosceles three-year Warrants to purchase 116,500 shares
of Viragen common stock at an exercise price of $0.25; three-year Warrants to
purchase 116,500 shares of Viragen common stock at an exercise price of $0.30
per share; three-year Warrants to purchase 116,500 shares of Viragen common
stock at an exercise price of $0.35 per share; three-year warrants to purchase
406,250 shares of Viragen common stock exercisable at $0.50 per share; and
three-year Warrants to purchase 375,000 shares of Viragen common stock
exercisable at $0.60 per share, with the latter two Warrants providing for the
right of Viragen to compel the exercise of such Warrants in the same manner as
provided to the investors in the above Securities Purchase Agreement. All of
such Warrants will have the same rights and protections as afforded to the
Warrants issued to the investors pursuant to the above Securities Purchase
Agreement. Viragen agrees to register the shares underlying the Warrants, at its
own cost, within 30 days after issuance and to process such registration
statement in an expeditious manner.

      6.    Except as modified herein, the Note shall remain in full force and
effect.

                To Purchase __________ Shares of Common Stock of

                                 VIRAGEN, INC.

            THIS CERTIFIES that, for value received, _____________ (the
"Holder"), is entitled, upon the terms and subject to the limitations on
exercise and the conditions hereinafter set forth, at any time on or after
February __, 2003 (the "Initial Exercise Date") and on or prior to the close of

share, of the Company (the "Common Stock"). The purchase price of one share of
Common Stock (the "Exercise Price") under this Warrant shall be $_____, subject
to adjustment hereunder. The Exercise Price and the number of Warrant Shares for
which the Warrant is exercisable shall be subject to adjustment as provided
herein. CAPITALIZED TERMS USED AND NOT OTHERWISE DEFINED HEREIN SHALL HAVE THE
MEANINGS SET FORTH IN THAT CERTAIN SECURITIES PURCHASE AGREEMENT (THE "PURCHASE
AGREEMENT"), DATED NOVEMBER 8, 2002, BETWEEN THE COMPANY AND THE INVESTORS
SIGNATORY THERETO.

                                       1
<PAGE>
            1. Title to Warrant. Prior to the Termination Date and subject to
compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company by the
Holder in person or by duly authorized attorney, upon surrender of this Warrant
together with the Assignment Form annexed hereto properly endorsed.

            2. Authorization of Shares. The Company covenants that all Warrant
Shares which may be issued upon the exercise of the purchase rights represented
by this Warrant will, upon exercise of the purchase rights represented by this
Warrant, be duly authorized, validly issued, fully paid and nonassessable and
free from all taxes, liens and charges in respect of the issue thereof (other
than taxes in respect of any transfer occurring contemporaneously with such
issue).

            3. Exercise of Warrant.

                  (a) Except as provided in Section 4 herein, exercise of the
      purchase rights represented by this Warrant may be made at any time or
      times on or after the Initial Exercise Date and on or before the
      Termination Date by the surrender of this Warrant and the Notice of
      Exercise Form annexed hereto duly executed, at the office of the Company
      (or such other office or agency of the Company as it may designate by
      notice in writing to the registered Holder at the address of such Holder
      appearing on the books of the Company) and upon payment of the Exercise
      Price of the shares thereby purchased by wire transfer or cashier's check
      drawn on a United States bank [OR BY MEANS OF A CASHLESS EXERCISE], the
      Holder shall be entitled to receive a certificate for the number of
      Warrant Shares so purchased. Certificates for shares purchased hereunder
      shall be delivered to the Holder within three (3) Trading Days after the
      date on which this Warrant shall have been exercised as aforesaid. This
      Warrant shall be deemed to have been exercised and such certificate or
      certificates shall be deemed to have been issued, and Holder or any other
      person so designated to be named therein shall be deemed to have become a
      holder of record of such shares for all purposes, as of the date the
      Warrant has been exercised by payment to the Company of the Exercise Price
      and all taxes required to be paid by the Holder, if any, pursuant to
      Section 5 prior to the issuance of such shares, have been paid. If the
      Company fails to deliver to the Holder a certificate or certificates
      representing the Warrant Shares pursuant to this Section 3(a) by the third
      Trading Day after the date of exercise, then the Holder will have the
      right to rescind such exercise. In addition to any other rights available
      to the Holder, if the Company fails to deliver to the Holder a certificate
      or certificates representing the Warrant Shares pursuant to an exercise by
      the fifth Trading Day after the date of exercise, and if after such fifth
      Trading Day the Holder purchases (in an open market transaction or
      otherwise) shares of Common Stock to deliver in satisfaction of a sale by
      the Holder of the Warrant Shares which the Holder anticipated receiving
      upon such exercise (a "Buy-In"), then the Company shall (1) pay in cash to
      the Holder the amount by which (x) the Holder's total purchase price
      (including brokerage commissions, if any) for the shares of Common Stock
      so purchased exceeds (y) the amount obtained by multiplying (A) the number
      of Warrant Shares that the Company was required to deliver to the Holder
      in connection

                                       2
<PAGE>
      with the exercise at issue times (B) the closing bid price of the Common
      Stock at the time of the obligation giving rise to such purchase
      obligation, and (2) at the option of the Holder, either reinstate the
      portion of the Warrant and equivalent number of Warrant Shares for which
      such exercise was not honored or deliver to the Holder the number of
      shares of Common Stock that would have been issued had the Company timely
      complied with its exercise and delivery obligations hereunder. For
      example, if the Holder purchases Common Stock having a total purchase
      price of $11,000 to cover a Buy-In with respect to an attempted exercise
      of shares of Common Stock with a market price on the date of exercise
      totaled $10,000, under clause (1) of the immediately preceding sentence
      the Company shall be required to pay the Holder $1,000. The Holder shall
      provide the Company written notice indicating the amounts payable to the
      Holder in respect of the Buy-In. Nothing herein shall limit a Holder's
      right to pursue any other remedies available to it hereunder, at law or in
      equity including, without limitation, a decree of specific performance
      and/or injunctive relief with respect to the Company's failure to timely
      deliver certificates representing shares of Common Stock upon exercise of
      the Warrant as required pursuant to the terms hereof.

                  (b) If this Warrant shall have been exercised in part, the
      Company shall, at the time of delivery of the certificate or certificates
      representing Warrant Shares, deliver to Holder a new Warrant evidencing
      the rights of Holder to purchase the unpurchased Warrant Shares called for
      by this Warrant, which new Warrant shall in all other respects be
      identical with this Warrant.

                  (c) Notwithstanding anything herein to the contrary, in no
      event shall the Holder be permitted to exercise this Warrant for Warrant
      Shares to the extent that (i) the number of shares of Common Stock owned
      by such Holder (other than Warrant Shares issuable upon exercise of this
      Warrant) plus (ii) the number of Warrant Shares issuable upon exercise of
      this Warrant, would be equal to or exceed 4.9999% of the number of shares
      of Common Stock then issued and outstanding, including shares issuable
      upon exercise of this Warrant held by such Holder after application of
      this Section 3(c). As used herein, beneficial ownership shall be
      determined in accordance with Section 13(d) of the Exchange Act. To the
      extent that the limitation contained in this Section 3(c) applies, the
      determination of whether this Warrant is exercisable (in relation to other
      securities owned by the Holder) and of which a portion of this Warrant is
      exercisable shall be in the sole discretion of such Holder, and the
      submission of a Notice of Exercise shall be deemed to be such Holder's
      determination of whether this Warrant is exercisable (in relation to other
      securities owned by such Holder) and of which portion of this Warrant is
      exercisable, in each case subject to such aggregate percentage limitation,
      and the Company shall have no obligation to verify or confirm the accuracy
      of such determination. Nothing contained herein shall be deemed to
      restrict the right of a Holder to exercise this Warrant into Warrant
      Shares at such time as such exercise will not violate the provisions of
      this Section 3(c). The provisions of this Section 3(c) may be waived by
      the Holder upon, at the election of the Holder, not less than 61 days'
      prior notice to the Company, and the provisions of this Section 3(c) shall
      continue to apply until such 61st day (or such later date, as determined
      by the Holder, as may be specified in such notice of waiver). No exercise
      of this Warrant in violation of this Section 3(c) but otherwise in

                                       3
<PAGE>
      accordance with this Warrant shall affect the status of the Warrant Shares
      as validly issued, fully-paid and nonassessable.

                  [(d) IF AFTER ONE YEAR IF THERE IS NO EFFECTIVE REGISTRATION
      STATEMENT REGISTERING THE WARRANT SHARES, THIS WARRANT MAY ALSO BE
      EXERCISED BY MEANS OF A "CASHLESS EXERCISE" IN WHICH THE HOLDER SHALL BE
      ENTITLED TO RECEIVE A CERTIFICATE FOR THE NUMBER OF WARRANT SHARES EQUAL
      TO THE QUOTIENT OBTAINED BY DIVIDING [(A-B) (X)] BY (A), WHERE:

            (A) = THE AVERAGE OF THE HIGH AND LOW TRADING PRICES PER SHARE OF
                  COMMON STOCK ON THE TRADING DAY PRECEDING THE DATE OF SUCH
                  ELECTION;

            (B) = THE EXERCISE PRICE OF THE WARRANTS; AND

            (X) = THE NUMBER OF WARRANT SHARES ISSUABLE UPON EXERCISE OF THE
                  WARRANTS IN ACCORDANCE WITH THE TERMS OF THIS WARRANT.]

      OF ANY PERIOD OF 10 CONSECUTIVE TRADING DAYS THAT THE CLOSING BID PRICE
      HAS EXCEEDED $_____, THE COMPANY SHALL HAVE THE RIGHT, UPON 15 DAYS
      ADVANCE WRITTEN NOTICE TO THE HOLDER, TO CAUSE THE HOLDER TO EXERCISE THE

            4. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to such fraction multiplied by
the Exercise Price.

            5. Charges, Taxes and Expenses. Issuance of certificates for Warrant
Shares shall be made without charge to the Holder for any issue or transfer tax
or other incidental expense in respect of the issuance of such certificate, all
of which taxes and expenses shall be paid by the Company, and such certificates
shall be issued in the name of the Holder or in such name or names as may be
directed by the Holder; provided, however, that in the event certificates for
Warrant Shares are to be issued in a name other than the name of the Holder,
this Warrant when surrendered for exercise shall be accompanied by the
Assignment Form attached hereto duly executed by the Holder; and the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

            6. Closing of Books. The Company will not close its stockholder
books or records in any manner which prevents the timely exercise of this
Warrant.

            7. Transfer, Division and Combination.

                  (a) Subject to compliance with any applicable securities laws,
      transfer of this Warrant and all rights hereunder, in whole or in part,
      shall be registered on the books of the Company to be maintained for such
      purpose, upon surrender of this Warrant at the principal office of the
      Company, together with a written assignment of this Warrant substantially
      in the form attached hereto duly executed by the Holder or its agent or
      attorney and funds sufficient to pay any transfer taxes payable upon the
      making of such transfer. Upon such surrender and, if required, such
      payment, the Company shall execute and deliver a new Warrant or Warrants
      in the name of the assignee or assignees and in the denomination or
      denominations specified in such instrument of assignment, and shall issue
      to the assignor a new Warrant evidencing the portion of this Warrant not
      so assigned, and this Warrant shall promptly be cancelled. A Warrant, if
      properly assigned, may be exercised by a new holder for the purchase of
      Warrant Shares without having a new Warrant issued.

                  (b) This Warrant may be divided or combined with other
      Warrants upon presentation hereof at the aforesaid office of the Company,
      together with a written notice specifying the names and denominations in
      which new Warrants are to be issued, signed by the Holder or its agent or
      attorney. Subject to compliance with Section 7(a), as to any transfer
      which may be involved in such division or combination, the Company shall
      execute and deliver a new Warrant or Warrants in exchange for the Warrant
      or Warrants to be divided or combined in accordance with such notice.

                  (c) The Company shall prepare, issue and deliver at its own
      expense (other than transfer taxes) the new Warrant or Warrants under this
      Section 7.

                                       6
<PAGE>
                  (d) The Company agrees to maintain, at its aforesaid office,
      books for the registration and the registration of transfer of the
      Warrants.

            8. No Rights as Shareholder until Exercise. This Warrant does not
entitle the Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise hereof. Upon the surrender of this Warrant and the
payment of the aggregate Exercise Price (or by means of a cashless exercise),
the Warrant Shares so purchased shall be and be deemed to be issued to such
Holder as the record owner of such shares as of the close of business on the
later of the date of such surrender or payment.

            9. Loss, Theft, Destruction or Mutilation of Warrant. The Company
covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock
certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which shall
not include the posting of any bond), and upon surrender and cancellation of
such Warrant or stock certificate, if mutilated, the Company will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

            10. Saturdays, Sundays, Holidays, etc. If the last or appointed day
for the taking of any action or the expiration of any right required or granted
herein shall be a Saturday, Sunday or a legal holiday, then such action may be
taken or such right may be exercised on the next succeeding day not a Saturday,
Sunday or legal holiday.

            11. Adjustments of Exercise Price and Number of Warrant Shares.

                  (a) Stock Splits, etc. The number and kind of securities
      purchasable upon the exercise of this Warrant and the Exercise Price shall
      be subject to adjustment from time to time upon the happening of any of
      the following. In case the Company shall (i) pay a dividend in shares of
      Common Stock or make a distribution in shares of Common Stock to holders
      of its outstanding Common Stock, (ii) subdivide its outstanding shares of
      Common Stock into a greater number of shares, (iii) combine its
      outstanding shares of Common Stock into a smaller number of shares of
      Common Stock, or (iv) issue any shares of its capital stock in a
      reclassification of the Common Stock, then the number of Warrant Shares
      purchasable upon exercise of this Warrant immediately prior thereto shall
      be adjusted so that the Holder shall be entitled to receive the kind and
      number of Warrant Shares or other securities of the Company which it would
      have owned or have been entitled to receive had such Warrant been
      exercised in advance thereof. Upon each such adjustment of the kind and
      number of Warrant Shares or other securities of the Company which are
      purchasable hereunder, the Holder shall thereafter be entitled to purchase
      the number of Warrant Shares or other securities resulting from such
      adjustment at an Exercise Price per Warrant Share or other security
      obtained by multiplying the Exercise Price in effect immediately prior to
      such adjustment by the number of Warrant Shares purchasable pursuant
      hereto immediately prior to such adjustment and dividing by the number of
      Warrant Shares or other securities of the Company resulting from such
      adjustment. An adjustment made pursuant to this paragraph shall become
      effective immediately after the effective date of such event retroactive
      to the record date, if any, for such event.

                  (b) [ONLY INCLUDED IN INCENTIVE WARRANTS] ANTI-DILUTION
      PROVISIONS. DURING THE EXERCISE PERIOD, THE EXERCISE PRICE AND THE NUMBER
      OF WARRANT SHARES ISSUABLE HEREUNDER AND FOR WHICH THIS WARRANT IS THEN
      EXERCISABLE PURSUANT TO SECTION 1 HEREOF SHALL BE SUBJECT TO ADJUSTMENT
      FROM TIME TO TIME AS PROVIDED IN THIS SECTION 11(B). IN THE EVENT THAT ANY
      ADJUSTMENT OF THE EXERCISE PRICE AS REQUIRED HEREIN RESULTS IN A FRACTION
      OF A CENT, SUCH EXERCISE PRICE SHALL BE ROUNDED UP OR DOWN TO THE NEAREST
      CENT.

                  (I) ADJUSTMENT OF EXERCISE PRICE. IF AND WHENEVER THE COMPANY
            ISSUES OR SELLS, OR IN ACCORDANCE WITH SECTION 8(B) HEREOF IS DEEMED
            TO HAVE ISSUED OR SOLD, ANY SHARES OF COMMON STOCK FOR A
            CONSIDERATION PER SHARE OF LESS THAN THE THEN THE EXERCISE PRICE OR
            FOR NO CONSIDERATION (SUCH LOWER PRICE, THE "BASE SHARE PRICE" AND
            SUCH ISSUANCES COLLECTIVELY, A "DILUTIVE ISSUANCE"), THEN, THE
            EXERCISE PRICE SHALL BE REDUCED TO A PRICE DETERMINED BY DIVIDING
            (I) AN AMOUNT EQUAL TO THE SUM OF (A) THE TOTAL NUMBER OF SHARES OF
            COMMON STOCK OUTSTANDING IMMEDIATELY PRIOR TO SUCH ISSUANCE OR SALE
            MULTIPLIED BY THE EXERCISE PRICE THEN IN EFFECT, PLUS (B) THE
            CONSIDERATION, IF ANY, RECEIVED BY THE COMPANY UPON SUCH ISSUANCE OR
            SALE, BY (II) THE TOTAL NUMBER OF SHARES OF COMMON STOCK OUTSTANDING
            IMMEDIATELY AFTER SUCH ISSUANCE OR SALE, PROVIDED, THAT FOR PURPOSES
            HEREOF, ALL SHARES OF COMMON STOCK THAT ARE ISSUABLE UPON
            CONVERSION, EXERCISE OR EXCHANGE OF CAPITAL SHARE EQUIVALENTS SHALL
            BE DEEMED OUTSTANDING IMMEDIATELY AFTER THE ISSUANCE OF SUCH COMMON
            STOCK. SUCH ADJUSTMENT SHALL BE MADE WHENEVER SUCH SHARES OF COMMON
            STOCK OR CAPITAL SHARE EQUIVALENTS ARE ISSUED.

                  (II) EFFECT ON EXERCISE PRICE OF CERTAIN EVENTS. FOR PURPOSES
            OF DETERMINING THE ADJUSTED EXERCISE PRICE UNDER SECTION 11(B)
            HEREOF, THE FOLLOWING WILL BE APPLICABLE:

                              (A) ISSUANCE OF RIGHTS OR OPTIONS. IF THE COMPANY
                  IN ANY MANNER ISSUES OR GRANTS ANY WARRANTS, RIGHTS OR
                  OPTIONS, WHETHER OR NOT IMMEDIATELY EXERCISABLE, TO SUBSCRIBE
                  FOR OR TO PURCHASE COMMON STOCK OR OTHER SECURITIES
                  EXERCISABLE, CONVERTIBLE INTO OR EXCHANGEABLE FOR COMMON STOCK
                  ("CONVERTIBLE SECURITIES") (SUCH WARRANTS, RIGHTS AND OPTIONS
                  TO PURCHASE COMMON STOCK OR CONVERTIBLE SECURITIES ARE
                  HEREINAFTER REFERRED TO AS "OPTIONS") AND THE PRICE PER SHARE
                  FOR WHICH COMMON STOCK IS ISSUABLE UPON THE EXERCISE OF SUCH
                  OPTIONS IS LESS THAN THE EXERCISE PRICE ("BELOW BASE PRICE
                  OPTIONS"), THEN THE MAXIMUM TOTAL NUMBER OF SHARES OF COMMON
                  STOCK ISSUABLE UPON THE EXERCISE OF ALL SUCH BELOW BASE PRICE
                  OPTIONS (ASSUMING FULL EXERCISE, CONVERSION OR EXCHANGE OF
                  CONVERTIBLE SECURITIES, IF APPLICABLE) WILL, AS OF THE DATE OF
                  THE ISSUANCE OR GRANT OF SUCH BELOW BASE PRICE OPTIONS, BE
                  DEEMED TO BE OUTSTANDING AND TO HAVE BEEN ISSUED AND SOLD BY
                  THE COMPANY FOR SUCH PRICE PER SHARE. FOR PURPOSES OF THE
                  PRECEDING SENTENCE, THE "PRICE PER SHARE FOR WHICH COMMON
                  STOCK IS ISSUABLE UPON THE EXERCISE OF SUCH BELOW BASE PRICE
                  OPTIONS" IS DETERMINED BY DIVIDING

                                       8
<PAGE>
                  (I) THE TOTAL AMOUNT, IF ANY, RECEIVED OR RECEIVABLE BY THE
                  COMPANY AS CONSIDERATION FOR THE ISSUANCE OR GRANTING OF ALL
                  SUCH BELOW BASE PRICE OPTIONS, PLUS THE MINIMUM AGGREGATE
                  AMOUNT OF ADDITIONAL CONSIDERATION, IF ANY, PAYABLE TO THE
                  COMPANY UPON THE EXERCISE OF ALL SUCH BELOW BASE PRICE
                  OPTIONS, PLUS, IN THE CASE OF CONVERTIBLE SECURITIES ISSUABLE
                  UPON THE EXERCISE OF SUCH BELOW BASE PRICE OPTIONS, THE
                  MINIMUM AGGREGATE AMOUNT OF ADDITIONAL CONSIDERATION PAYABLE
                  UPON THE EXERCISE, CONVERSION OR EXCHANGE THEREOF AT THE TIME
                  SUCH CONVERTIBLE SECURITIES FIRST BECOME EXERCISABLE,
                  CONVERTIBLE OR EXCHANGEABLE, BY (II) THE MAXIMUM TOTAL NUMBER
                  OF SHARES OF COMMON STOCK ISSUABLE UPON THE EXERCISE OF ALL
                  SUCH BELOW BASE PRICE OPTIONS (ASSUMING FULL CONVERSION OF
                  CONVERTIBLE SECURITIES, IF APPLICABLE). NO FURTHER ADJUSTMENT
                  TO THE EXERCISE PRICE WILL BE MADE UPON THE ACTUAL ISSUANCE OF
                  SUCH COMMON STOCK UPON THE EXERCISE OF SUCH BELOW BASE PRICE
                  OPTIONS OR UPON THE EXERCISE, CONVERSION OR EXCHANGE OF
                  CONVERTIBLE SECURITIES ISSUABLE UPON EXERCISE OF SUCH BELOW
                  BASE PRICE OPTIONS.

                              (B) ISSUANCE OF CONVERTIBLE SECURITIES. IF THE
                  COMPANY IN ANY MANNER ISSUES OR SELLS ANY CONVERTIBLE
                  SECURITIES, WHETHER OR NOT IMMEDIATELY CONVERTIBLE (OTHER THAN
                  WHERE THE SAME ARE ISSUABLE UPON THE EXERCISE OF OPTIONS) AND
                  THE PRICE PER SHARE FOR WHICH COMMON STOCK IS ISSUABLE UPON
                  SUCH EXERCISE, CONVERSION OR EXCHANGE IS LESS THAN THE
                  EXERCISE PRICE, THEN THE MAXIMUM TOTAL NUMBER OF SHARES OF
                  COMMON STOCK ISSUABLE UPON THE EXERCISE, CONVERSION OR
                  EXCHANGE OF ALL SUCH CONVERTIBLE SECURITIES WILL, AS OF THE
                  DATE OF THE ISSUANCE OF SUCH CONVERTIBLE SECURITIES, BE DEEMED
                  TO BE OUTSTANDING AND TO HAVE BEEN ISSUED AND SOLD BY THE
                  COMPANY FOR SUCH PRICE PER SHARE. FOR THE PURPOSES OF THE
                  PRECEDING SENTENCE, THE "PRICE PER SHARE FOR WHICH COMMON
                  STOCK IS ISSUABLE UPON SUCH EXERCISE, CONVERSION OR EXCHANGE"
                  IS DETERMINED BY DIVIDING (I) THE TOTAL AMOUNT, IF ANY,
                  RECEIVED OR RECEIVABLE BY THE COMPANY AS CONSIDERATION FOR THE
                  ISSUANCE OR SALE OF ALL SUCH CONVERTIBLE SECURITIES, PLUS THE
                  MINIMUM AGGREGATE AMOUNT OF ADDITIONAL CONSIDERATION, IF ANY,
                  PAYABLE TO THE COMPANY UPON THE EXERCISE, CONVERSION OR
                  EXCHANGE THEREOF AT THE TIME SUCH CONVERTIBLE SECURITIES FIRST
                  BECOME EXERCISABLE, CONVERTIBLE OR EXCHANGEABLE, BY (II) THE
                  MAXIMUM TOTAL NUMBER OF SHARES OF COMMON STOCK ISSUABLE UPON
                  THE EXERCISE, CONVERSION OR EXCHANGE OF ALL SUCH CONVERTIBLE
                  SECURITIES. NO FURTHER ADJUSTMENT TO THE EXERCISE PRICE WILL
                  BE MADE UPON THE ACTUAL ISSUANCE OF SUCH COMMON STOCK UPON
                  EXERCISE, CONVERSION OR EXCHANGE OF SUCH CONVERTIBLE
                  SECURITIES.

                              (C) CHANGE IN OPTION PRICE OR CONVERSION RATE. IF
                  THERE IS A CHANGE AT ANY TIME IN (I) THE AMOUNT OF ADDITIONAL
                  CONSIDERATION PAYABLE TO THE COMPANY UPON THE EXERCISE OF ANY

                                       9
<PAGE>
                  OPTIONS; (II) THE AMOUNT OF ADDITIONAL CONSIDERATION, IF ANY,
                  PAYABLE TO THE COMPANY UPON THE EXERCISE, CONVERSION OR
                  EXCHANGE OF ANY CONVERTIBLE SECURITIES; OR (III) THE RATE AT
                  WHICH ANY CONVERTIBLE SECURITIES ARE CONVERTIBLE INTO OR
                  EXCHANGEABLE FOR COMMON STOCK (IN EACH SUCH CASE, OTHER THAN
                  UNDER OR BY REASON OF PROVISIONS DESIGNED TO PROTECT AGAINST
                  DILUTION), THE EXERCISE PRICE IN EFFECT AT THE TIME OF SUCH
                  CHANGE WILL BE READJUSTED TO THE EXERCISE PRICE WHICH WOULD
                  HAVE BEEN IN EFFECT AT SUCH TIME HAD SUCH OPTIONS OR
                  CONVERTIBLE SECURITIES STILL OUTSTANDING PROVIDED FOR SUCH
                  CHANGED ADDITIONAL CONSIDERATION OR CHANGED CONVERSION RATE,
                  AS THE CASE MAY BE, AT THE TIME INITIALLY GRANTED, ISSUED OR
                  SOLD.

                              (D) CALCULATION OF CONSIDERATION RECEIVED. IF ANY
                  COMMON STOCK, OPTIONS OR CONVERTIBLE SECURITIES ARE ISSUED,
                  GRANTED OR SOLD FOR CASH, THE CONSIDERATION RECEIVED THEREFOR
                  FOR PURPOSES OF THIS WARRANT WILL BE THE AMOUNT RECEIVED BY
                  THE COMPANY THEREFOR, BEFORE DEDUCTION OF REASONABLE
                  COMMISSIONS, UNDERWRITING DISCOUNTS OR ALLOWANCES OR OTHER
                  REASONABLE EXPENSES PAID OR INCURRED BY THE COMPANY IN
                  CONNECTION WITH SUCH ISSUANCE, GRANT OR SALE. IN CASE ANY
                  COMMON STOCK, OPTIONS OR CONVERTIBLE SECURITIES ARE ISSUED OR
                  SOLD FOR A CONSIDERATION PART OR ALL OF WHICH SHALL BE OTHER
                  THAN CASH, THE AMOUNT OF THE CONSIDERATION OTHER THAN CASH
                  RECEIVED BY THE COMPANY WILL BE THE FAIR MARKET VALUE OF SUCH
                  CONSIDERATION, EXCEPT WHERE SUCH CONSIDERATION CONSISTS OF
                  SECURITIES, IN WHICH CASE THE AMOUNT OF CONSIDERATION RECEIVED
                  BY THE COMPANY WILL BE THE MARKET PRICE THEREOF AS OF THE DATE
                  OF RECEIPT. IN CASE ANY COMMON STOCK, OPTIONS OR CONVERTIBLE
                  SECURITIES ARE ISSUED IN CONNECTION WITH ANY MERGER OR
                  CONSOLIDATION IN WHICH THE COMPANY IS THE SURVIVING
                  CORPORATION, THE AMOUNT OF CONSIDERATION THEREFOR WILL BE
                  DEEMED TO BE THE FAIR MARKET VALUE OF SUCH PORTION OF THE NET
                  ASSETS AND BUSINESS OF THE NON-SURVIVING CORPORATION AS IS
                  ATTRIBUTABLE TO SUCH COMMON STOCK, OPTIONS OR CONVERTIBLE
                  SECURITIES, AS THE CASE MAY BE. THE FAIR MARKET VALUE OF ANY
                  CONSIDERATION OTHER THAN CASH OR SECURITIES WILL BE DETERMINED
                  IN GOOD FAITH BY AN INVESTMENT BANKER OR OTHER APPROPRIATE
                  EXPERT OF NATIONAL REPUTATION SELECTED BY THE COMPANY AND
                  REASONABLY ACCEPTABLE TO THE HOLDER HEREOF, WITH THE COSTS OF
                  SUCH APPRAISAL TO BE BORNE BY THE COMPANY.

                              (E) EXCEPTIONS TO ADJUSTMENT OF EXERCISE PRICE. NO
                  ADJUSTMENT TO THE EXERCISE PRICE WILL BE MADE UPON THE GRANT
                  OR EXERCISE OF ANY CONVERTIBLE SECURITIES WHICH MAY HEREAFTER
                  BE GRANTED OR EXERCISED UNDER ANY EMPLOYEE BENEFIT PLAN OF THE
                  COMPANY NOW EXISTING OR TO BE IMPLEMENTED IN THE FUTURE, SO
                  LONG AS THE ISSUANCE OF SUCH CONVERTIBLE SECURITIES IS
                  APPROVED BY A MAJORITY OF THE NON-EMPLOYEE MEMBERS OF THE
                  BOARD OF DIRECTORS OF THE COMPANY OR A

                                       10
<PAGE>
                  MAJORITY OF THE MEMBERS OF A COMMITTEE OF NON-EMPLOYEE
                  DIRECTORS ESTABLISHED FOR SUCH PURPOSE.

                  (III) MINIMUM ADJUSTMENT OF EXERCISE PRICE. NO ADJUSTMENT OF
            THE EXERCISE PRICE SHALL BE MADE IN AN AMOUNT OF LESS THAN 1% OF THE
            EXERCISE PRICE IN EFFECT AT THE TIME SUCH ADJUSTMENT IS OTHERWISE
            REQUIRED TO BE MADE, BUT ANY SUCH LESSER ADJUSTMENT SHALL BE CARRIED
            FORWARD AND SHALL BE MADE AT THE TIME AND TOGETHER WITH THE NEXT
            SUBSEQUENT ADJUSTMENT WHICH, TOGETHER WITH ANY ADJUSTMENTS SO
            CARRIED FORWARD, SHALL AMOUNT TO NOT LESS THAN 1% OF SUCH EXERCISE
            PRICE.

            12. Reorganization, Reclassification, Merger, Consolidation or
Disposition of Assets. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is a change in or distribution with respect to the Common Stock of the Company),
or sell, transfer or otherwise dispose of all or substantially all its property,
assets or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Stock
of the Company, then the Holder shall have the right thereafter to receive, at
their option, (a) upon exercise of this Warrant, the number of shares of Common
Stock of the successor or acquiring corporation or of the Company, if it is the
surviving corporation, and Other Property receivable upon or as a result of such
reorganization, reclassification, merger, consolidation or disposition of assets
by a Holder of the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to such event, or (b) only if the Company is not
the surviving corporation and the Closing Bid Price immediately prior to such
event is less than 110% of the Exercise Price, cash equal to the value of this
Warrant as determined in accordance with the Black-Sholes option pricing formula
which amount shall in no event exceed 150% of the product of the Exercise Price
and the number of Warrant Shares issuable hereunder. In case of any such
reorganization, reclassification, merger, consolidation or disposition of
assets, the successor or acquiring corporation (if other than the Company) shall
expressly assume the due and punctual observance and performance of each and
every covenant and condition of this Warrant to be performed and observed by the
Company and all the obligations and liabilities hereunder, subject to such
modifications as may be deemed appropriate (as determined in good faith by
resolution of the Board of Directors of the Company) in order to provide for
adjustments of Warrant Shares for which this Warrant is exercisable which shall
be as nearly equivalent as practicable to the adjustments provided for in this
Section 12. For purposes of this Section 12, "common stock of the successor or
acquiring corporation" shall include stock of such corporation of any class
which is not preferred as to dividends or assets over any other class of stock
of such corporation and which is not subject to redemption and shall also
include any evidences of indebtedness, shares of stock or other securities which
are convertible into or exchangeable for any such stock, either immediately or
upon the arrival of a specified date or the happening of a specified event and
any warrants or other rights to subscribe for or purchase any such stock. The
foregoing provisions of this Section 12 shall

                                       11
<PAGE>
similarly apply to successive reorganizations, reclassifications, mergers,
consolidations or disposition of assets.

            13. Voluntary Adjustment by the Company. The Company may at any time
during the term of this Warrant reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Company.

            14. Notice of Adjustment. Whenever the number of Warrant Shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company
shall promptly mail by registered or certified mail, return receipt requested,
to the Holder notice of such adjustment or adjustments setting forth the number
of Warrant Shares (and other securities or property) purchasable upon the
exercise of this Warrant and the Exercise Price of such Warrant Shares (and
other securities or property) after such adjustment, setting forth a brief
statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made. Such notice, in the absence of
manifest error, shall be conclusive evidence of the correctness of such
adjustment.

            15. Notice of Corporate Action. If at any time:

                  (a) the Company shall take a record of the holders of its
      Common Stock for the purpose of entitling them to receive a dividend or
      other distribution, or any right to subscribe for or purchase any
      evidences of its indebtedness, any shares of stock of any class or any
      other securities or property, or to receive any other right, or

                  (b) there shall be any capital reorganization of the Company,
      any reclassification or recapitalization of the capital stock of the
      Company or any consolidation or merger of the Company with, or any sale,
      transfer or other disposition of all or substantially all the property,
      assets or business of the Company to, another corporation or,

                  (c) there shall be a voluntary or involuntary dissolution,
      liquidation or winding up of the Company;

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 20 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 20
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause also shall specify (i) the date
on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their

                                       12
<PAGE>
Warrant Shares for securities or other property deliverable upon such
disposition, dissolution, liquidation or winding up. Each such written notice
shall be sufficiently given if addressed to Holder at the last address of Holder
appearing on the books of the Company and delivered in accordance with Section
17(d).

            16. Authorized Shares. The Company covenants that during the period
the Warrant is outstanding, it will reserve from its authorized and unissued
Common Stock a sufficient number of shares to provide for the issuance of the
Warrant Shares upon the exercise of any purchase rights under this Warrant. The
Company further covenants that its issuance of this Warrant shall constitute
full authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such
Warrant Shares may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of the Principal Market
upon which the Common Stock may be listed.

                  The Company shall not by any action, including, without
limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of Holder against impairment. Without limiting the generality of the
foregoing, the Company will (a) not increase the par value of any Warrant Shares
above the amount payable therefor upon such exercise immediately prior to such
increase in par value, (b) take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable Warrant Shares upon the exercise of this Warrant, and (c) use
commercially reasonable efforts to obtain all such authorizations, exemptions or
consents from any public regulatory body having jurisdiction thereof as may be
necessary to enable the Company to perform its obligations under this Warrant.

                  Before taking any action which would result in an adjustment
in the number of Warrant Shares for which this Warrant is exercisable or in the
Exercise Price, the Company shall obtain all such authorizations or exemptions
thereof, or consents thereto, as may be necessary from any public regulatory
body or bodies having jurisdiction thereof.

            17. Miscellaneous.

                  (a) Jurisdiction. This Warrant shall constitute a contract
      under the laws of New York, without regard to its conflict of law,
      principles or rules.

                  (b) Restrictions. The Holder acknowledges that the Warrant
      Shares acquired upon the exercise of this Warrant, if not registered, will
      have restrictions upon resale imposed by state and federal securities
      laws.

                  (c) Nonwaiver and Expenses. No course of dealing or any delay
      or failure to exercise any right hereunder on the part of Holder shall
      operate as a waiver of such

                                       13
<PAGE>
      right or otherwise prejudice Holder's rights, powers or remedies,
      notwithstanding all rights hereunder terminate on the Termination Date. If
      the Company willfully and knowingly fails to comply with any provision of
      this Warrant, which results in any material damages to the Holder, the
      Company shall pay to Holder such amounts as shall be sufficient to cover
      any costs and expenses including, but not limited to, reasonable
      attorneys' fees, including those of appellate proceedings, incurred by
      Holder in collecting any amounts due pursuant hereto or in otherwise
      enforcing any of its rights, powers or remedies hereunder.

                  (d) Notices. Any notice, request or other document required or
      permitted to be given or delivered to the Holder by the Company shall be
      delivered in accordance with the notice provisions of the Purchase
      Agreement.

                  (e) Limitation of Liability. No provision hereof, in the
      absence of affirmative action by Holder to purchase Warrant Shares, and no
      enumeration herein of the rights or privileges of Holder, shall give rise
      to any liability of Holder for the purchase price of any Common Stock or
      as a stockholder of the Company, whether such liability is asserted by the
      Company or by creditors of the Company.

                  (f) Remedies. Holder, in addition to being entitled to
      exercise all rights granted by law, including recovery of damages, will be
      entitled to specific performance of its rights under this Warrant. The
      Company agrees that monetary damages would not be adequate compensation
      for any loss incurred by reason of a breach by it of the provisions of
      this Warrant and hereby agrees to waive the defense in any action for
      specific performance that a remedy at law would be adequate.

                  (g) Successors and Assigns. Subject to applicable securities
      laws, this Warrant and the rights and obligations evidenced hereby shall
      inure to the benefit of and be binding upon the successors of the Company
      and the successors and permitted assigns of Holder. The provisions of this
      Warrant are intended to be for the benefit of all Holders from time to
      time of this Warrant and shall be enforceable by any such Holder or holder
      of Warrant Shares.

                  (h) Amendment. This Warrant may be modified or amended or the
      provisions hereof waived with the written consent of the Company and the
      Holder.

                  (i) Severability. Wherever possible, each provision of this
      Warrant shall be interpreted in such manner as to be effective and valid
      under applicable law, but if any provision of this Warrant shall be
      prohibited by or invalid under applicable law, such provision shall be
      ineffective to the extent of such prohibition or invalidity, without
      invalidating the remainder of such provisions or the remaining provisions
      of this Warrant.

                  (j) Headings. The headings used in this Warrant are for the
      convenience of reference only and shall not, for any purpose, be deemed a
      part of this Warrant.

                   NOTICE OF EXERCISE OF COMMON STOCK WARRANT
                    PURSUANT TO CASHLESS EXERCISE PROVISIONS

To: Viragen, Inc.

Aggregate Price of Warrant Before Exercise: $_______
Aggregate Price Being Exercised: $______
Exercise Price: $______ per share
Number of Shares of Common Stock to be Issued Under this Notice: ________
Remaining Aggregate Price (if any) After Issuance: $_______

Gentlemen:

      The undersigned, registered Holder of the Warrant delivered herewith,
hereby irrevocably exercises such Warrant for, and purchases thereunder, shares
of the Common Stock of Viragen, Inc., as provided below. Capitalized terms used
herein, unless otherwise defined herein, shall have the meanings given in the
Warrant. The portion of the Exercise Price (as defined in the Warrant) to be
applied toward the purchase of Common Stock pursuant to this Notice of Exercise
is $_______, thereby leaving a remaining Exercise Price (if any) equal to
$________. Such exercise shall be pursuant to the cashless exercise provisions
of Section 3 of the Warrant; therefore, Holder makes no payment with this Notice
of Exercise. The number of shares to be issued pursuant to this exercise shall
be determined by reference to the formula in Section 3 of the Warrant which, by
reference to Section 3, requires the use of the high and low trading price of
the Company's Common Stock on the Trading Day preceding the date of such
election. The high and low trading price of the Company's Common Stock has been
determined by Holder to be $______ and $_________, respectively, which figure is
acceptable to Holder for calculations of the number of shares of Common Stock
issuable pursuant to this Notice of Exercise. Holder requests that the
certificates for the purchased shares of Common Stock be issued in the name of
_________________________ and delivered to ____________________________________.
To the extent the foregoing exercise is for less than the full Aggregate Price
of the Warrant, a replacement Warrant representing the remainder of the
Aggregate Price (and otherwise of like form, tenor and effect) shall be
delivered to Holder along with the share certificate evidencing the Common Stock
issued in response to this Notice of Exercise.

                                      NOTE
