         Re:      First Amendment to the Securities Purchase Agreement

Ladies and Gentlemen:

         1.       Reference is made to that certain Securities Purchase
Agreement (the "Purchase Agreement"), dated January 31, 2003, between Viragen,
Inc. (the "Company"), Alpha Capital AG, Palisades Equity Fund L.P (collectively
the "Participating Purchasers") and the other purchasers signatory thereto, and
the exhibits entered into pursuant thereto. Capitalized terms used but not
defined herein shall have the meanings set forth in the Purchase Agreement. In
consideration of the mutual covenants and agreements contained herein, and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the Participating Purchasers hereby agree to purchase,
severally and not jointly, an additional $375,000 principal amount of Secured
Convertible Debentures in the form of the debentures sold pursuant to the
Purchase Agreement (the "Debentures"), on the same terms and conditions and with
the same rights, privileges and obligations thereunder, for the amounts set
forth below each such Participating Purchaser's name on the signature pages
hereto. Set forth on Annex I attached hereto is a list of the Debentures,
warrants (the "Warrants") and shares of common stock of the Company ("Common
Stock") issuable to each Participating Purchaser hereunder. The parties hereto
agree and acknowledge that the securities issued and issuable hereunder shall be
included in the definition of Securities and Underlying Securities,
respectively, as those terms are defined in the Purchase Agreement. The holders
of the securities issued and issuable hereunder shall have all of the rights and
remedies under the Purchase Agreement and the exhibits thereto. Each
Participating Purchasers agrees and acknowledges that the purchase of securities
hereunder does

<PAGE>
Page 2

not entitle such Participating Purchaser to any additional shares of Common
Stock issuable under the Issuable Maximum (as set forth in Annex A to the
Purchase Agreement) that it may otherwise be entitled to by virtue of its
purchase of the securities hereunder until after Shareholder Approval.

         2.       Registration Rights Agreement. The Common Stock underlying the
Debentures and Warrants and the shares issuable in connection herewith, as set
forth on Annex I, are hereby included in the definition of Registrable
Securities in the Registration Rights Agreement and the holders thereof shall
have all of the rights and remedies as a holder of Registrable Securities
thereunder.

         3.       Escrow Agreement. The purchase and sale of the Debentures will
occur through the Escrow Agent and otherwise pursuant to the terms of the Escrow
Agreement, as if such purchase and sale had occurred at the Closing.

         4.       Authorization. The Company has the requisite power and
authority to enter into and perform this letter agreement, to sell the
Debentures, and to issue the securities issued and issuable hereunder. The
execution, delivery and performance of this letter agreement by the Company and
the consummation by it of the transactions contemplated hereby have been duly
authorized by all necessary corporate action and shall constitute valid and
binding obligations of the Company enforceable against the Company in accordance
with their terms.

         5.       Representations and Warranties. Except as set forth on the
schedules attached hereto or the SEC Reports, the representations and warranties
of the Company set forth in the Purchase Agreement are true and correct in all
material respects as though made on and as of the date hereof and all SEC
Reports are as represented in the Purchase Agreement.

         6.       Covenants. Except as set forth on the schedules hereto, the
Company has performed in all material respects all covenants and agreements to
be performed by the Company under the Purchase Agreement on or prior to the date
hereof and has complied and will comply in all material respects with all of the
Company's obligations and conditions contained in the Purchase Agreement.

         7.       Force of Amendment. Except as specifically amended by the
terms of this Amendment, the Purchase Agreement and its exhibits shall remain
unmodified and in full force and effect, and shall not be in any way changed,
modified or superseded by the terms set forth herein. Specifically, the Closing
Date for purposes of determining the Company's obligations under the
Registration Rights Agreement with respect to all Registrable Securities, as
amended hereunder, shall remain January 31, 2003.

         8.       Counterparts. This amendment may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
instrument and shall become effective when counterparts have been signed by each
party and delivered to the other parties hereto, it being understood that all
parties need not sign the same counterpart. Execution may be made by delivery by
facsimile.

NEITHER THESE SECURITIES NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE

                                            Date of Issuance: February 28, 2003

                                                                       $250,000

                         SECURED CONVERTIBLE DEBENTURE
                             DUE FEBRUARY 28, 2005

THIS DEBENTURE is one of a series of duly authorized and issued debentures of
Viragen, Inc., a Delaware corporation, having a principal place of business at
865 S.W. 78th Avenue, Suite 100, Plantation, Florida 33324 (the "Company"),
designated as its Secured Convertible Debentures, due February 28, 2005 (the
"Debentures").

         FOR VALUE RECEIVED, the Company promises to pay to Palisades Equity
Fund L.P. or its registered assigns (the "Holder"), the principal sum of
$250,000 on February 28, 2005 or such earlier date as the Debentures are
required or permitted to be repaid as provided hereunder (the "Maturity Date")
and to pay interest to the Holder on the aggregate unconverted and then
outstanding principal amount of this Debenture at the rate of 0% per annum
until February 28, 2004 and 6% per annum thereafter, payable semi-annually on
June 1 and December 1, beginning on June 1, 2004 and on each Conversion Date
(as defined herein) and on the Maturity Date (each such date, an "Interest
Payment Date"), in cash or shares of Common Stock (as defined in Section 5) at
the Interest Conversion Rate; provided, however, payment in shares of Common
Stock may only occur if: (i) there is an effective Underlying Shares
Registration Statement pursuant to which the Holder is permitted to utilize the
prospectus thereunder to resell all of the shares of Common Stock to be issued
in lieu of cash (and the Company believes, in good faith, that such
effectiveness will continue

<PAGE>

uninterrupted for the foreseeable future), (ii) the Common Stock is listed for
trading on a Principal Market (and the Company believes, in good faith, that
trading of the Common Stock on a Principal Market will continue uninterrupted
for the foreseeable future), (iii) there is a sufficient number of authorized
but unissued and otherwise unreserved shares of Common Stock for the issuance
of all of the share issuable pursuant to the Transaction Documents, including
the shares to be issued for interest in lieu of cash and (iv) the Company shall
have obtained Shareholder Approval to exceed the Issuable Maximum. The Company
may not prepay any portion of the principal amount or interest on this
Debenture without the prior written consent of the Holder, other than as
provided herein. Subject to the terms and conditions herein, the decision
whether to pay interest hereunder in shares of Common Stock or cash shall be at
the discretion of the Company. Not less than twenty Trading Days (as defined in
Section 5) prior to each Interest Payment Date, the Company shall provide the
Holder with written notice of its election to pay interest hereunder either in
cash or shares of Common Stock pursuant to the terms of Section 4 (the Company
may indicate in such notice that the election contained in such notice shall
continue for later periods until revised). Subject to the aforementioned
conditions, failure to timely provide such written notice shall be deemed an
election by the Company to pay the interest on such Conversion Date in cash.
Interest shall be calculated on the basis of a 360-day year and shall accrue
daily commencing on the Original Issue Date (as defined in Section 5) until
payment in full of the principal sum, together with all accrued and unpaid
interest and other amounts which may become due hereunder, has been made.
Interest hereunder will be paid to the Person (as defined in Section 5) in
whose name this Debenture is registered on the records of the Company regarding
registration and transfers of Debentures (the "Debenture Register"). All
overdue accrued and unpaid interest to be paid hereunder shall entail a late
fee at the rate of 18% per annum (or such lower maximum amount of interest
permitted to be charged under applicable law) ("Late Fee") which will accrue
daily, from the date such interest is due hereunder through and including the
date of payment.

         This Debenture is subject to the following additional provisions:

         Section 1.        This Debenture is exchangeable for an equal aggregate
principal amount of Debentures of different authorized denominations, as
requested by the Holder surrendering the same. No service charge will be made
for such registration of transfer or exchange.

         Section 2.        This Debenture has been issued subject to certain
investment representations of the original Holder set forth in the Purchase
Agreement (as defined in Section 5) and may be transferred or exchanged only in
compliance with the Purchase Agreement. Prior to due presentment to the Company
for transfer of this Debenture, the Company and any agent of the Company may
treat the Person (as defined in Section 5) in whose name this Debenture is duly
registered on the Debenture Register as the owner hereof for the purpose of
receiving payment as herein provided and for all other purposes, whether or not
this Debenture is overdue, and neither the Company nor any such agent shall be
affected by notice to the contrary.

                  days from the Event Date (as defined in the Registration
                  Rights Agreement) relating thereto (other than an Event
                  resulting from a failure of an Underlying Shares Registration
                  Statement to be declared effective by the Commission on or
                  prior to the 150th calendar day after the Original Issue Date,
                  which shall be covered by Section 3(a)(vii));

                           (x)      the Company shall fail for any reason to
                  deliver certificates to a Holder prior to the fifth Trading
                  Day after a Conversion Date pursuant to and in accordance with
                  Section 4(b) or the Company shall provide notice to the
                  Holder, including by way of public announcement, at any time,
                  of its intention not to comply with requests for conversions
                  of any Debentures in accordance with the terms hereof; or

                           (xi)     upon 1 Trading Day's notice, the Company
                  shall fail for any reason to deliver the payment in cash
                  pursuant to a Buy-In (as defined herein) within five days
                  after notice thereof is delivered hereunder.

                  (b)      If any Event of Default occurs and is continuing, the
         full principal amount of this Debenture (and, at the Holder's option,
         all other Debentures then held by such Holder), together with interest
         and other amounts owing in respect thereof, to the date of acceleration
         shall become at the Holder's election, immediately due and payable in
         cash. The aggregate amount payable upon an Event of Default shall be
         equal to the sum of: (i) the Mandatory Prepayment Amount (as defined in
         Section 5) plus (ii) the product of (A) the number of Underlying Shares
         issued in respect of conversions hereunder within thirty days of the
         date of a declaration of an Event of Default and then held by the
         Holder and (B) the Closing Bid Price (as defined in Section 5) on the
         date prepayment is due or the date the full prepayment price is paid,
         whichever is greater. Interest shall accrue on the prepayment amount
         hereunder from the 5th day after such amount is due (being the date of
         an Event of Default) through the date of prepayment in full thereof in
         an amount equal to the Late Fee, to accrue daily from the date such
         payment is due hereunder through and including the date of payment. All
         Debentures and Underlying Shares for which the full prepayment price
         hereunder shall have been paid in accordance herewith shall promptly be
         surrendered to or as directed by the Company. The Holder need not
         provide and the Company hereby waives any presentment, demand, protest
         or other notice of any kind, and the Holder may immediately and without
         expiration of any grace period enforce any and all of its rights and
         remedies hereunder and all other remedies available to it under
         applicable law; provided, however, the Holder shall have the right to
         waive any Event of Default which has occurred and such waivers shall be
         retroactive to the date such Event of Default occurred. Such
         declaration may be rescinded and annulled by Holder at any time prior
         to payment hereunder and the Holder shall have all rights as a
         Debenture holder until such time, if any, as the full payment under
         this Section shall have been received by it. No such rescission or
         annulment shall affect any subsequent Event of Default or impair any
         right consequent thereon.

         Section 4.        Conversion.

                  (a)      (i) At any time after the Closing Date, this
                  Debenture shall be convertible into shares of Common Stock at
                  the option of the Holder, in whole or in part at any time and
                  from time to time (subject to the limitations on conversion
                  set forth in Section 4(a)(ii) hereof). The Holder shall effect
                  conversions by delivering to the Company the form of
                  conversion notice attached hereto as Annex A (a "Conversion
                  Notice"), specifying therein the principal amount of
                  Debentures to be converted and the date on which such
                  conversion is to be effected (a "Conversion Date"). If no
                  Conversion Date is specified in a Conversion Notice, the
                  Conversion Date shall be the date that such Conversion Notice
                  is provided hereunder. To effect conversions hereunder, the
                  Holder shall not be required to physically surrender
                  Debentures to the Company unless the entire principal amount
                  of this Debenture has been so converted. Conversions hereunder
                  shall have the effect of lowering the outstanding principal
                  amount of this Debenture plus all accrued and unpaid interest
                  thereon in an amount equal to the applicable conversion. The
                  Holder and the Company shall maintain records showing the
                  principal amount converted and the date of such conversions,
                  in a form substantially similar to Schedule 1 attached hereto.
                  In the event of any dispute or discrepancy, the records of the
                  Holder shall be controlling and determinative in the absence
                  of manifest error. The Holder and any assignee, by acceptance
                  of this Debenture, acknowledge and agree that, by reason of
                  the provisions of this paragraph, following conversion of a
                  portion of this Debenture, the unpaid and unconverted
                  principal amount of this Debenture may be less than the amount
                  stated on the face hereof.

                           (ii)     A Holder may not convert Debentures or
                  receive shares of Common Stock as payment of interest
                  hereunder to the extent such conversion or receipt of such
                  interest payment would result in the Holder, together with its
                  affiliates, beneficially owning (as determined in accordance
                  with Section 13(d) of the Exchange Act and the rules
                  promulgated thereunder) in excess of 4.999% of the then issued
                  and outstanding shares of Common Stock, including shares
                  issuable upon conversion of, and payment of interest on, the
                  Debentures held by such Holder after application of this
                  Section. To ensure compliance with this restriction, the
                  Holder will be deemed to represent to the Company each time it
                  delivers a Conversion Notice that such Conversion Notice has
                  not violated the restrictions set forth in this paragraph. If
                  the Holder has delivered a Conversion Notice for a principal
                  amount of Debentures that, without regard to any other shares
                  that the Holder or its affiliates may beneficially own, would
                  result in the issuance in excess of the permitted amount
                  hereunder, the Company shall notify the Holder of this fact
                  and shall honor the conversion for the maximum principal
                  amount permitted to be converted on such Conversion Date in
                  accordance with the periods described in Section 4(b) and, at
                  the option of the Holder, either retain any principal amount
                  tendered for conversion in excess of the permitted amount
                  hereunder for future conversions or return such excess
                  principal

                  amount to the Holder. In the event of a merger or
                  consolidation of the Company with or into another Person, this
                  paragraph shall not apply with respect to a determination of
                  the number of shares of common stock issuable upon conversion
                  in full of the Debentures if such determination is necessary
                  to establish the Securities or other assets which the holder
                  of Common Stock shall be entitled to receive upon the
                  effectiveness of such merger or consolidation. The provisions
                  of this Section 4(a)(ii) 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
                  4(a)(iii) 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).

                           (iii)    If the Company has not obtained Shareholder
                  Approval, then the Company may not issue, pursuant to the
                  Transaction Documents, in the aggregate, in excess of 19.999%
                  of the number of shares of Common Stock outstanding on the
                  Original Issue Date (such number of shares, the "Issuable
                  Maximum"). Each Holder shall be entitled to a portion of the
                  Issuable Maximum equal to the quotient obtained by dividing
                  (x) the aggregate principal amount of the Debenture(s) issued
                  and sold to such Holder on the Original Issue Date by (y) the
                  aggregate principal amount of all Debentures issued and sold
                  by the Company on the Original Issue Date. If any Holder shall
                  no longer hold the Debenture(s), then such Holder's remaining
                  portion of the Issuable Maximum shall be allocated pro-rata
                  among the remaining Holders. Within 60 days of the Original
                  Issue Date, the Company shall obtain the vote of shareholders
                  (the "Shareholder Approval") as may be required by the
                  applicable rules and regulations of the Principal Market (or
                  any successor entity) applicable to approve the issuance of
                  shares of Common Stock in excess of the Issuable Maximum
                  pursuant to the Transaction Documents. If the Company shall
                  have not obtained the Shareholder Approval on or before 60
                  days from the Original Issue Date, then the Company shall
                  issue to the Holder, upon conversion of this Debenture, a
                  number of shares of Common Stock equal to such Holder's
                  pro-rata portion (which shall be calculated pursuant to the
                  terms hereof) of the Issuable Maximum and, with respect to the
                  remainder of the aggregate principal amount of the Debentures
                  (including any interest that shall have been added to the
                  principal amount then held by such Holder) for which a
                  conversion in accordance with the applicable conversion price
                  would result in an issuance of shares of Common Stock in
                  excess of such Holder's pro-rata portion (which shall be
                  calculated pursuant to the terms hereof) of the Issuable
                  Maximum (the "Excess Principal"), the Company shall, by the
                  fifth Trading Day following such conversion, pay cash to the
                  converting Holder in an amount equal to the Mandatory
                  Prepayment Amount with respect to such Excess Principal. If
                  the Company fails to pay the Mandatory Prepayment Amount for
                  the Excess Principal in full pursuant to this Section after
                  the date payable, the Company will pay interest thereon at a
                  rate of 18% per annum or such lesser maximum amount that is
                  permitted to be paid by applicable law, to the converting
                  Holder, accruing daily from the date such payment is due until
                  such amount, plus all such interest

                  thereon, is paid in full. The Company and the Holder
                  understand and agree that shares of Common Stock issued to and
                  then held by the Holder as a result of conversions of
                  Debentures shall not be entitled to cast votes on any
                  resolution to obtain Shareholder Approval pursuant hereto.

                           (iv)     Underlying Shares Issuable Upon Conversion
                  and Pursuant to Interest.

                                    (A)      The number of shares of Common
                           Stock issuable upon a conversion hereunder shall be
                           determined by adding the sum of: (1) the quotient
                           obtained by dividing (x) the outstanding principal
                           amount of this Debenture to be converted by (y) the
                           Set Price, and (2) the amount equal to (x) the
                           product of (I) the outstanding principal amount of
                           this Debenture to be converted and (II) the product
                           of (aa) the quotient obtained by dividing the
                           applicable interest rate on this Debenture by 360 and
                           (bb) the number of days for which such principal
                           amount was outstanding, divided by (y) the lesser of
                           the Set Price and the Interest Conversion Rate on the
                           Conversion Date, provided, that if the Company shall
                           have elected to pay the interest due on a Conversion
                           Date in cash pursuant to the terms hereof, subsection
                           (2) shall not be used in the calculation of the
                           number of shares of Common Stock issuable upon a
                           conversion hereunder.

                                    (B)      Notwithstanding anything to the
                           contrary contained herein, if on any Conversion Date:

                                             (1)      the number of shares of
                                    Common Stock at the time authorized,
                                    unissued and unreserved for all purposes, or
                                    held as treasury stock, is insufficient to
                                    pay interest hereunder in shares of Common
                                    Stock;

                                             (3)      the Common Stock shall
                                    fail to be listed or quoted for trading on a
                                    Principal Market; or

                                             (4)      the conversion would
                                    otherwise violate Section 4(a)(iii).

                                    then, at the option of the Holder, the
                           Company, in lieu of delivering shares of Common Stock
                           pursuant to this Section 4, shall deliver, within
                           three Trading Days of each applicable Conversion
                           Date, an amount in cash equal to the product of the
                           number of shares of Common Stock otherwise
                           deliverable to the Holder in connection with such
                           Conversion Date and the highest Closing Bid Price
                           during the period commencing on the Conversion Date
                           and ending on the Trading Day prior to the date such
                           payment is made.

                  (b)      (i)      Not later than three Trading Days after any
         Conversion Date, the Company will deliver to the Holder (A) the number
         of shares of Common Stock being acquired upon conversion of the
         Debenture (the "Conversion Shares") in the form of a certificate or
         certificates which shall be free of restrictive legends and trading
         restrictions (other than those required by the Purchase Agreement)
         representing the number of shares of Common Stock being acquired upon
         the conversion of Debentures and (B) a bank check in the amount of
         accrued and unpaid interest (if the Company has timely elected or is
         required to pay accrued interest in cash). Provided the Registration
         Statement is then effective, the Company shall, upon request of the
         Holder, if available, deliver any certificate or certificates required
         to be delivered by the Company under this Section electronically
         through the Depository Trust Corporation or another established
         clearing corporation performing similar functions. If in the case of
         any Conversion Notice such Conversion Shares are not delivered to or as
         directed by the applicable Holder by the third Trading Day after a
         Conversion Date, the Holder shall be entitled by written notice to the
         Company at any time on or before its receipt of such Conversion Shares,
         to rescind such conversion, in which event the Company shall, if
         applicable, immediately return the certificates representing the
         principal amount of Debentures tendered for conversion.

                           (ii)     If the Company fails for any reason to
                  deliver to the Holder the Conversion Shares pursuant to
                  Section 4(b)(i) by the third Trading Day after the Conversion
                  Date, the Company shall pay to such Holder, in cash, as
                  liquidated damages and not as a penalty, for each $5,000 of
                  principal amount being converted, $50 per Trading Day
                  (increasing to $100 per Trading Day after 3 Trading Days and
                  increasing to $200 per Trading Day 6 Trading Days after such
                  damages begin to accrue) for each Trading Day after such third
                  Trading Day until such Conversion Shares are delivered. In the
                  event a Holder of this Debenture shall elect to convert any or
                  all of the outstanding principal amount hereof, the Company
                  may not refuse conversion based on any claim that the Holder
                  or any one associated or affiliated with the Holder of has
                  been engaged in any violation of law, agreement or for any
                  other reason, unless, an injunction from a court, on notice,
                  restraining and or enjoining conversion of all or part of this
                  Debenture shall have been sought and obtained and the Company
                  posts a surety bond for the benefit of the Holder in the
                  amount of 150% of the principal amount of this Debenture
                  outstanding, which is subject to the injunction, which bond
                  shall remain in effect until the completion of
                  arbitration/litigation of the dispute and the proceeds of
                  which shall be payable to such Holder to the extent it obtains
                  judgment. In the absence of an injunction precluding the same,
                  the Company shall issue Conversion Shares or, if applicable,
                  cash, upon a properly noticed conversion. Nothing herein shall
                  limit a Holder's right to pursue actual damages or declare an
                  Event of Default pursuant to Section 3 herein for the
                  Company's failure to deliver Conversion Shares within the
                  period specified herein and such Holder shall have the right
                  to pursue all remedies available to it at law or in equity
                  including, without limitation, a decree of specific
                  performance and/or injunctive relief. The exercise of

                  any such rights shall not prohibit the Holders from seeking to
                  enforce damages pursuant to any other Section hereof or under
                  applicable law.

                           (iii)    In addition to any other rights available to
                  the Holder, if the Company fails for any reason to deliver to
                  the Holder such certificate or certificates pursuant to
                  Section 4(b)(i) by the fifth Trading Day after the Conversion
                  Date, and if after such third Trading Day the Holder purchases
                  (in an open market transaction or otherwise) Common Stock to
                  deliver in satisfaction of a sale by such Holder of the
                  Underlying Shares which the Holder anticipated receiving upon
                  such conversion (a "Buy-In"), then the Company shall (A) pay
                  in cash to the Holder (in addition to any remedies available
                  to or elected by the Holder) the amount by which (x) the
                  Holder's total purchase price (including brokerage
                  commissions, if any) for the Common Stock so purchased exceeds
                  (y) the product of (1) the aggregate number of shares of
                  Common Stock that such Holder anticipated receiving from the
                  conversion at issue multiplied by (2) the market price of the
                  Common Stock at the time of the sale giving rise to such
                  purchase obligation and (B) at the option of the Holder,
                  either reissue Debentures in principal amount equal to the
                  principal amount of the attempted conversion or deliver to the
                  Holder the number of shares of Common Stock that would have
                  been issued had the Company timely complied with its delivery
                  requirements under Section 4(b)(i). 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
                  conversion of Debentures with respect to which the market
                  price of the Underlying Shares on the date of conversion was a
                  total of $10,000 under clause (A) 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. Notwithstanding anything contained herein to the
                  contrary, if a Holder requires the Company to make payment in
                  respect of a Buy-In for the failure to timely deliver
                  Conversion Shares hereunder and the Company timely pays in
                  full such payment, the Company shall not be required to pay
                  such Holder liquidated damages under Section 4(b)(ii) in
                  respect of the Conversion Shares resulting in such Buy-In.

                  (c)      (i)      The conversion price in effect on any
         Conversion Date shall be equal to $0.085 (subject to adjustment
         herein)(the "Set Price").

                           (ii)     If the Company, at any time while the
                  Debentures are outstanding: (A) shall pay a stock dividend or
                  otherwise make a distribution or distributions on shares of
                  its Common Stock or any other equity or equity equivalent
                  securities payable in shares of Common Stock, (B) subdivide
                  outstanding shares of Common Stock into a larger number of
                  shares, (C) combine (including by way of reverse stock split)
                  outstanding shares of Common Stock into a smaller number of
                  shares, or (D) issue by reclassification of shares of the
                  Common Stock any shares of capital stock of the Company, then
                  the Set Price shall be multiplied by a fraction of which the
                  numerator

                                       10
<PAGE>

                  shall be the number of shares of Common Stock (excluding
                  treasury shares, if any) outstanding before such event and of
                  which the denominator shall be the number of shares of Common
                  Stock outstanding after such event. Any adjustment made
                  pursuant to this Section shall become effective immediately
                  after the record date for the determination of stockholders
                  entitled to receive such dividend or distribution and shall
                  become effective immediately after the effective date in the
                  case of a subdivision, combination or re-classification.

                           (iii)    If the Company, at any time while Debentures
                  are outstanding, shall issue rights, options or warrants to
                  all holders of Common Stock (and not to Holders) entitling
                  them to subscribe for or purchase shares of Common Stock at a
                  price per share less than the Closing Bid Price at the record
                  date mentioned below, then the Set Price shall be multiplied
                  by a fraction, of which the denominator shall be the number of
                  shares of the Common Stock (excluding treasury shares, if any)
                  outstanding on the date of issuance of such rights or warrants
                  plus the number of additional shares of Common Stock offered
                  for subscription or purchase, and of which the numerator shall
                  be the number of shares of the Common Stock (excluding
                  treasury shares, if any) outstanding on the date of issuance
                  of such rights or warrants plus the number of shares which the
                  aggregate offering price of the total number of shares so
                  offered would purchase at such Closing Bid Price. Such
                  adjustment shall be made whenever such rights or warrants are
                  issued, and shall become effective immediately after the
                  record date for the determination of stockholders entitled to
                  receive such rights, options or warrants.

                           (iv)     If the Company or any subsidiary thereof, as
                  applicable, at any time while Debentures are outstanding,
                  shall offer, sell, grant any option to purchase or offer, sell
                  or grant any right to reprice its securities, or otherwise
                  dispose of or issue (or announce any offer, sale, grant or any
                  option to purchase or other disposition) any Common Stock or
                  any equity or equity equivalent securities (including any
                  equity, debt or other instrument that is at any time over the
                  life thereof convertible into or exchangeable for Common
                  Stock) (collectively, "Common Stock Equivalents") entitling
                  any Person to acquire shares of Common Stock, at a price per
                  share less than the Set Price (if the holder of the Common
                  Stock or Common Stock Equivalent so issued shall at any time,
                  whether by operation of purchase price adjustments, reset
                  provisions, floating conversion, exercise or exchange prices
                  or otherwise, or due to warrants, options or rights per share
                  which is issued in connection with such issuance, be entitled
                  to receive shares of Common Stock at a price per share which
                  is less than the Set Price, such issuance shall be deemed to
                  have occurred for less than the Set Price), then, the Set
                  Price shall be adjusted for such conversions as Holders shall
                  indicate in its Conversion Notices to equal the conversion,
                  exchange or purchase price for such Common Stock or Common
                  Stock Equivalents (including any reset provisions thereof) at
                  issue. Such adjustment shall be made whenever such Common
                  Stock or Common Stock Equivalents are issued. The Company
                  shall notify

                                       11
<PAGE>

                  the Holder in writing, no later than the business day
                  following the issuance of any Common Stock or Common Stock
                  Equivalent subject to this section, indicating therein the
                  applicable issuance price, or of applicable reset price,
                  exchange price, conversion price and other pricing terms.

                           (v)      If the Company, at any time while Debentures
                  are outstanding, shall distribute to all holders of Common
                  Stock (and not to Holders) evidences of its indebtedness or
                  assets or rights or warrants to subscribe for or purchase any
                  security, then in each such case the Set Price shall be
                  determined by multiplying such price in effect immediately
                  prior to the record date fixed for determination of
                  stockholders entitled to receive such distribution by a
                  fraction of which the denominator shall be the Closing Bid
                  Price determined as of the record date mentioned above, and of
                  which the numerator shall be such Closing Bid Price on such
                  record date less the then fair market value at such record
                  date of the portion of such assets or evidence of indebtedness
                  so distributed applicable to one outstanding share of the
                  Common Stock as determined by the Board of Directors in good
                  faith. In either case the adjustments shall be described in a
                  statement provided to the Holders of the portion of assets or
                  evidences of indebtedness so distributed or such subscription
                  rights applicable to one share of Common Stock. Such
                  adjustment shall be made whenever any such distribution is
                  made and shall become effective immediately after the record
                  date mentioned above.

                           (vi)     In case of any reclassification of the
                  Common Stock or any compulsory share exchange pursuant to
                  which the Common Stock is converted into other securities,
                  cash or property, the Holders shall have the right thereafter
                  to, at their option, (A) convert the then outstanding
                  principal amount, together with all accrued but unpaid
                  interest and any other amounts then owing hereunder in respect
                  of this Debenture only into the shares of stock and other
                  securities, cash and property receivable upon or deemed to be
                  held by holders of the Common Stock following such
                  reclassification or share exchange, and the Holders of the
                  Debentures shall be entitled upon such event to receive such
                  amount of securities, cash or property as the shares of the
                  Common Stock of the Company into which the then outstanding
                  principal amount, together with all accrued but unpaid
                  interest and any other amounts then owing hereunder in respect
                  of this Debenture could have been converted immediately prior
                  to such reclassification or share exchange would have been
                  entitled or (B) require the Company to prepay the aggregate of
                  its outstanding principal amount of Debentures, plus all
                  interest and other amounts due and payable thereon, at a price
                  determined in accordance with Section 3(b). The entire
                  prepayment price shall be paid in cash. This provision shall
                  similarly apply to successive reclassifications or share
                  exchanges.

                           (vii)    All calculations under this Section 4 shall
                  be made to the nearest cent or the nearest 1/100th of a share,
                  as the case may be.

                           (viii)   Whenever the Set Price is adjusted pursuant
                  to any of Section 4(c)(ii) - (v), the Company shall promptly
                  mail to each Holder a notice setting forth the Set Price after
                  such adjustment and setting forth a brief statement of the
                  facts requiring such adjustment.

                           (ix)     If (A) the Company shall declare a dividend
                  (or any other distribution) on the Common Stock; (B) the
                  Company shall declare a special nonrecurring cash dividend on
                  or a redemption of the Common Stock; (C) the Company shall
                  authorize the granting to all holders of the Common Stock
                  rights or warrants to subscribe for or purchase any shares of
                  capital stock of any class or of any rights; (D) the approval
                  of any stockholders of the Company shall be required in
                  connection with any reclassification of the Common Stock, any
                  consolidation or merger to which the Company is a party, any
                  sale or transfer of all or substantially all of the assets of
                  the Company, of any compulsory share exchange whereby the
                  Common Stock is converted into other securities, cash or
                  property; (E) the Company shall authorize the voluntary or
                  involuntary dissolution, liquidation or winding up of the
                  affairs of the Company; then, in each case, the Company shall
                  cause to be filed at each office or agency maintained for the
                  purpose of conversion of the Debentures, and shall cause to be
                  mailed to the Holders at their last addresses as they shall
                  appear upon the stock books of the Company, at least 20
                  calendar days prior to the applicable record or effective date
                  hereinafter specified, a notice stating (x) the date on which
                  a record is to be taken for the purpose of such dividend,
                  distribution, redemption, rights or warrants, or if a record
                  is not to be taken, the date as of which the holders of the
                  Common Stock of record to be entitled to such dividend,
                  distributions, redemption, rights or warrants are to be
                  determined or (y) the date on which such reclassification,
                  consolidation, merger, sale, transfer or share exchange is
                  expected to become effective or close, and the date as of
                  which it is expected that holders of the Common Stock of
                  record shall be entitled to exchange their shares of the
                  Common Stock for securities, cash or other property
                  deliverable upon such reclassification, consolidation, merger,
                  sale, transfer or share exchange; provided, that the failure
                  to mail such notice or any defect therein or in the mailing
                  thereof shall not affect the validity of the corporate action
                  required to be specified in such notice. Holders are entitled
                  to convert Debentures during the 20-day period commencing the
                  date of such notice to the effective date of the event
                  triggering such notice.

                           (x)      If, at any time while this Debenture is
                  outstanding, (A) the Company effects any merger or
                  consolidation of the Company with or into another Person, (B)
                  the Company effects any sale of all or substantially all of
                  its assets in one or a series of related transactions, (C) any
                  tender offer or exchange offer (whether by the Company or
                  another Person) is completed pursuant to which holders of
                  Common Stock are permitted to tender or exchange their shares
                  for other securities, cash or property, or (D) the Company
                  effects any reclassification of the Common Stock or any

                  compulsory share exchange pursuant to which the Common Stock
                  is effectively converted into or exchanged for other
                  securities, cash or property (in any such case, a "Fundamental
                  Transaction"), then upon any subsequent conversion of this
                  Debenture, the Holder shall have the right to receive, for
                  each Underlying Share that would have been issuable upon such
                  conversion absent such Fundamental Transaction, the same kind
                  and amount of securities, cash or property as it would have
                  been entitled to receive upon the occurrence of such
                  Fundamental Transaction if it had been, immediately prior to
                  such Fundamental Transaction, the holder of one share of
                  Common Stock (the "Alternate Consideration"). For purposes of
                  any such conversion, the determination of the Set Price shall
                  be appropriately adjusted to apply to such Alternate
                  Consideration based on the amount of Alternate Consideration
                  issuable in respect of one share of Common Stock in such
                  Fundamental Transaction, and the Company shall apportion the
                  Set Price among the Alternate Consideration in a reasonable
                  manner reflecting the relative value of any different
                  components of the Alternate Consideration. If holders of
                  Common Stock are given any choice as to the securities, cash
                  or property to be received in a Fundamental Transaction, then
                  the Holder shall be given the same choice as to the Alternate
                  Consideration it receives upon any conversion of this
                  Debenture following such Fundamental Transaction. To the
                  extent necessary to effectuate the foregoing provisions, any
                  successor to the Company or surviving entity in such
                  Fundamental Transaction shall issue to the Holder a new
                  debenture consistent with the foregoing provisions and
                  evidencing the Holder's right to convert such debenture into
                  Alternate Consideration. The terms of any agreement pursuant
                  to which a Fundamental Transaction is effected shall include
                  terms requiring any such successor or surviving entity to
                  comply with the provisions of this paragraph (c) and insuring
                  that this Debenture (or any such replacement security) will be
                  similarly adjusted upon any subsequent transaction analogous
                  to a Fundamental Transaction. If any Fundamental Transaction
                  constitutes or results in a Change of Control Transaction,
                  then at the request of the Holder delivered before the 90th
                  day after such Fundamental Transaction, the Company (or any
                  such successor or surviving entity) will purchase the
                  Debenture from the Holder for a purchase price, payable in
                  cash within five Trading Days after such request (or, if
                  later, on the effective date of the Fundamental Transaction),
                  equal to the Black-Scholes value of the remaining unconverted
                  portion of this Debenture on the date of such request, which
                  value shall in no event exceed 150% of the principal amount
                  outstanding of this Debenture.

                  (d)      The Company covenants that it will at all times
         reserve and keep available out of its authorized and unissued shares of
         Common Stock solely for the purpose of issuance upon conversion of the
         Debentures and payment of interest on the Debentures, each as herein
         provided, free from preemptive rights or any other actual contingent
         purchase rights of persons other than the Holders, not less than such
         number of shares of the Common Stock as shall (subject to any
         additional requirements of the Company as to reservation of such shares
         set forth in the Purchase Agreement) be issuable (taking into account
         the adjustments and

                                       14
<PAGE>

         restrictions of Section 4(b)) upon the conversion of the outstanding
         principal amount of the Debentures and payment of interest hereunder.
         The Company covenants that all shares of Common Stock that shall be so
         issuable shall, upon issue, be duly and validly authorized, issued and
         fully paid, nonassessable and, if the Underlying Shares Registration
         Statement has been declared effective under the Securities Act,
         registered for public sale in accordance with such Underlying Shares
         Registration Statement.

                  (e)      Upon a conversion hereunder the Company shall not be
         required to issue stock certificates representing fractions of shares
         of the Common Stock, but may if otherwise permitted, make a cash
         payment in respect of any final fraction of a share based on the
         Closing Bid Price at such time. If the Company elects not, or is
         unable, to make such a cash payment, the Holder shall be entitled to
         receive, in lieu of the final fraction of a share, one whole share of
         Common Stock.

                  (f)      The issuance of certificates for shares of the Common
         Stock on conversion of the Debentures shall be made without charge to
         the Holders thereof for any documentary stamp or similar taxes that may
         be payable in respect of the issue or delivery of such certificate,
         provided that the Company shall not be required to pay any tax that may
         be payable in respect of any transfer involved in the issuance and
         delivery of any such certificate upon conversion in a name other than
         that of the Holder of such Debentures so converted and the Company
         shall not be required to issue or deliver such certificates unless or
         until the person or persons requesting the issuance thereof shall have
         paid to the Company the amount of such tax or shall have established to
         the satisfaction of the Company that such tax has been paid.

                  (g)      Any and all notices or other communications or
         deliveries to be provided by the Holders hereunder, including, without
         limitation, any Conversion Notice, shall be in writing and delivered
         personally, by facsimile, sent by a nationally recognized overnight

         Section. Any and all notices or other communications or deliveries to

         such facsimile telephone number or address appears, at the principal

         deliveries hereunder shall be deemed given and effective on the

         Days' prior written notice to the Holder (an "Optional Redemption
         Notice" and the date such notice is received by the Holder, the "Notice
         Date"), to redeem no less than the entire principal amount of this

         the principal amount outstanding plus interest and any fees owing
         thereon (the "Optional Redemption Price"). The Company may only effect
         an Optional Redemption Notice if each of the following shall be true:
         (i) the Company shall have duly honored all conversions occurring by
         virtue of one or more Conversion Notices prior to the Optional
         Redemption Notice, (ii) there is an effective Underlying Shares
         Registration Statement pursuant to which the Holder is permitted to

         Shares issued to the Holder and all of the Underlying Shares as are
         issuable to the Holder upon conversion in full of this Debenture
         subject to the Optional Redemption Notice (and the Company believes, in
         good faith, that such effectiveness will continue uninterrupted for the
         foreseeable future), (iii) the Common Stock is listed for trading on a
         Principal Market (and the Company believes, in good faith, that trading
         of the Common Stock on a Principal Market will continue uninterrupted
         for the foreseeable future), (iv) all liquidated damages and other
         amounts owing in respect of the Debentures and Underlying Shares shall
         have been paid or will, concurrently with the issuance of the
         Underlying Shares, be paid in cash; (v) there is a sufficient number of
         authorized but unissued and otherwise unreserved shares of Common Stock
         for the issuance of all the Underlying Shares as are issuable to the
         Holder upon conversion in full of the Debentures subject to the
         Optional Redemption Notice; (vi) no Event of Default nor any event that
         with the passage of time would constitute an Event of Default has
         occurred and is continuing; (vii) no public announcement of a pending
         or proposed Change of Control Transaction or Fundamental Transaction
         has occurred that has not been consummated and (viii) the Company shall
         have obtained Shareholder Approval to exceed the Issuable Maximum. If
         any of the foregoing conditions shall cease to be in effect

                                       18
<PAGE>

         during the period between the Notice Date and the date the Optional
         Redemption Price is paid in full, then the Holders subject to such
         redemption may elect, by written notice to the Company given at any
         time after any of the foregoing conditions shall cease to be in effect,
         to invalidate ab initio such redemption, notwithstanding anything
         herein contained to the contrary. In any case, the Holders may convert
         any portion of the outstanding principal amount of the Debentures
         subject to an Optional Redemption Notice prior to the date that the
         Optional Redemption Price is due and paid in full.

                  (b)      Conditional Redemption at Election of Holder. On any
         Conversion Date after the earlier of the Effective Date or the 90th day
         after the Closing Date, if the Closing Bid Price for the 20 consecutive
         Trading Day period prior to such date is less than 120% of the Set
         Price then in effect, the Holder shall have the right to cause the
         Company to, at the election of the Company, either (i) redeem the
         portion of this Debenture then subject to the Conversion Notice
         applicable to such Conversion Date based on a redemption price equal to
         125% of the principal amount of such principal amount (the "Conditional
         Redemption Price") or (ii) in lieu of a cash redemption payment, issue
         Conversion Shares based on a conversion price equal to 75% of the
         average of the last 5 Closing Bid Prices during such 20 day period;
         provided, however, if, on the applicable Conversion Date, there is an
         effective Registration Statement pursuant to which the prospectus
         thereunder is available to resell Conversion Shares issued to the
         Holder, the Company must first issue shares registered pursuant to such
         Registration Statement. Notwithstanding anything to the contrary
         herein, the Company acknowledges and agrees that, to the extent the
         Company exceeds the Issuable Maximum, it must pay any Conditional
         Redemption Price in cash until Shareholder Approval is obtained. The
         Company must notify the Holder of its election to pay the Conditional
         Redemption Price in cash or shares of Common Stock within 24 hours
         after notification from the Holder that the Holder elects to exercise
         its right to a redemption hereunder. All conversions hereunder shall be
         made as if pursuant to Section 4 and the other sub-sections relating
         thereto, including but not limited to, liquidated damages and fees for
         late delivery of Conversion Shares. Nothing herein shall preclude the
         Holder from converting this Debenture to the extent this Debenture
         remains unpaid and unconverted after the Mandatory Redemption Date.

                  (c)      Redemption Procedure. The Optional Redemption Price
         is due on the 10th Trading Day following the Notice Date and the
         Conditional Redemption Price is due on the 10th Trading Day following
         the Conversion Date unless otherwise paid in shares of Common Stock. If
         any portion of the Optional Redemption Price or Conditional Redemption
         Price shall not be paid by the Company by expiration of such 10th
         Trading Day, interest shall accrue thereon at the rate of 18% per annum
         (or the maximum rate permitted by applicable law, whichever is less)
         until such redemption price plus all such interest is paid in full. In
         addition, if any portion of the Optional Redemption Price or
         Conditional Redemption Price remains unpaid after such date, the
         Holders subject to such redemption may elect, by written notice to the
         Company given at any time thereafter, to invalidate ab initio such
         redemption, notwithstanding anything herein contained to the contrary.
         If a Holder elects to invalidate

                                       19
<PAGE>

         such redemption the Company shall promptly, and, in any event, not
         later than 3 Trading Days from receipt of such Holder's notice of such
         election, return to such Holder all of the Debentures for which the
         Optional Redemption Price or Conditional Redemption Price shall not
         have been paid in full.

         Section 7.        Except as expressly provided herein, no provision of
this Debenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of, interest and liquidated
damages (if any) on, this Debenture at the time, place, and rate, and in the
coin or currency, herein prescribed. This Debenture is a direct obligation of
the Company and is secured by a floating charge in all of the assets of Viragen
(Scotland) Ltd. as set forth in that certain Bond and Floating Charge, dated as
of the date of the Purchase Agreement. This Debenture ranks pari passu with all
other Debentures now or hereafter issued under the terms set forth herein. As
long as there are Debentures outstanding, the Company shall not and shall cause
it subsidiaries not to, without the consent of the Holders, (a) amend its
certificate of incorporation, bylaws or other charter documents so as to
adversely affect any rights of the Holders; (b) repay, repurchase or offer to
repay, repurchase or otherwise acquire shares of its Common Stock or other
equity securities other than as to the Underlying Shares to the extent permitted
or required under the Transaction Documents; or (c) enter into any agreement
with respect to any of the foregoing.

      Section 8.           If this Debenture shall be mutilated, lost, stolen or
destroyed, the Company shall execute and deliver, in exchange and substitution
for and upon cancellation of a mutilated Debenture, or in lieu of or in
substitution for a lost, stolen or destroyed debenture, a new Debenture for the
principal amount of this Debenture so mutilated, lost, stolen or destroyed but
only upon receipt of evidence of such loss, theft or destruction of such
Debenture, and of the ownership hereof, and indemnity, if requested, all
reasonably satisfactory to the Company.

      Section 9.           The Company will not and will not permit any of its
subsidiaries to, directly or indirectly, enter into, create, incur, assume or
suffer to exist any indebtedness of any kind, on or with respect to any of its
property or assets now owned or hereafter acquired or any interest therein or
any income or profits therefrom that is senior in any respect to the Company's
obligations under the Debentures.

      Section 10.          All questions concerning the construction, validity,
enforcement and interpretation of this Debenture shall be governed by and
construed and enforced in accordance with the internal laws of the State of New
York, without regard to the principles of conflicts of law thereof. Each party
agrees that all legal proceedings concerning the interpretations, enforcement
and defense of the transactions contemplated by any of the Transaction Documents
(whether brought against a party hereto or its respective affiliates, directors,
officers, shareholders, employees or agents) shall be commenced in the state and
federal courts sitting in the City of New York, Borough of Manhattan (the "New
York Courts"). Each party hereto hereby irrevocably submits to the exclusive

assert in any suit, action or proceeding, any claim that it is not personally
subject to the jurisdiction of any such court, or such New York Courts are
improper or inconvenient venue for such proceeding. Each party hereby
irrevocably waives personal service of process and consents to process being
served in any such suit, action or proceeding by mailing a copy thereof via
registered or certified mail or overnight delivery (with evidence of delivery)
to such party at the address in effect for notices to it under this Debenture
and agrees that such service shall constitute good and sufficient service of
process and notice thereof. Nothing contained herein shall be deemed to limit in
any way any right to serve process in any manner permitted by law. Each party
hereto hereby irrevocably waives, to the fullest extent permitted by applicable
law, any and all right to trial by jury in any legal proceeding arising out of
or relating to this Debenture or the transactions contemplated hereby. If either
party shall commence an action or proceeding to enforce any provisions of this
Debenture, then the prevailing party in such action or proceeding shall be
reimbursed by the other party for its attorneys fees and other costs and
expenses incurred with the investigation, preparation and prosecution of such
action or proceeding.

      Section 11.          Any waiver by the Company or the Holder of a breach
of any provision of this Debenture shall not operate as or be construed to be a
waiver of any other breach of such provision or of any breach of any other
provision of this Debenture. The failure of the Company or the Holder to insist
upon strict adherence to any term of this Debenture on one or more occasions
shall not be considered a waiver or deprive that party of the right thereafter
to insist upon strict adherence to that term or any other term of this
Debenture. Any waiver must be in writing.

      Section 12.          If any provision of this Debenture is invalid,
illegal or unenforceable, the balance of this Debenture shall remain in effect,
and if any provision is inapplicable to any person or circumstance, it shall
nevertheless remain applicable to all other persons and circumstances. If it
shall be found that any interest or other amount deemed interest due hereunder
shall violate applicable laws governing usury, the applicable rate of interest
due hereunder shall automatically be lowered to equal the maximum permitted rate
of interest. The Company covenants (to the extent that it may lawfully do so)
that it shall not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay, extension or usury law or
other law which would prohibit or forgive the Company from paying all or any
portion of the principal of or interest on the Debentures as contemplated
herein, wherever enacted, now or at any time hereafter in force, or which may
affect the covenants or the performance of this indenture, and the Company (to
the extent it may lawfully do so) hereby expressly waives all benefits or
advantage of any such law, and covenants that it will not, by resort to any such
law, hinder, delay or impeded the execution of any power herein granted to the
Holder, but will suffer and permit the execution of every such as though no such
law has been enacted.

      Section 13.          Whenever any payment or other obligation hereunder
shall be due on a day other than a Business Day, such payment shall be made on
the next succeeding Business Day.
