ITEM 5 - OTHER EVENTS

      On  December  9, 1996,  the Company  issued  5,000  shares of its Series C
Convertible Preferred Stock in consideration for $5,000,000.  The purchases were
made by Strome Hedgecap Limited,  Strome Offshore Limited, Strome Partners, L.P.
and Strome Susskind Hedgecap, L.P. (collectively the "Purchasers"),  pursuant to
separate Securities Purchase  Agreements.  In addition,  Warrants to purchase an
aggregate of 214,593  shares of Common Stock,  exercisable at $2.00 per share on
or prior to December 9, 1999, were issued to the Purchasers.

      At the  option  of each of the  Purchasers,  up to 25% of their  shares of
Series C Preferred Stock may be  convertible,  on or after 10 days from the date
that the underlying shares of Common Stock have been registered with the SEC for
public  resale,  into shares of the  Company's  Common Stock on the basis of one
share of Series C Preferred  Stock for shares of Common Stock equal in number to
the amount determined by dividing $1,000 (representing the stated value thereof)
by the closing  price of the  Company's  Common Stock over the five-day  trading
period  ending  on the day prior to the  conversion  of the  Series C  Preferred
Stock.  An additional 25% of the Series C Preferred Stock will be convertible on
or after the 30th,  60th and 90th day  thereafter  on a  cumulative  basis.  The
conversion  price  per share  may not be less  than  $3.46 nor more than  $7.00;
provided,  however,  in the event the conversion  price would be less than $3.46
but for such minimum conversion price, the difference between $3.46 and what the
conversion  price would have been except for such minimum  price,  multiplied by
the number of shares of Common Stock issued upon conversion, will be paid to the
holder in cash upon conversion. Any shares of Series C Preferred Stock which are
outstanding on December 5, 1997 will be  automatically  converted into shares of
Common Stock based on the  conversion  price at such time computed in accordance
with the above procedure.

      With  respect to the  Warrants,  as to each of the  Purchasers,  an amount
equal to 25% of such Warrants are  exercisable on or after the first  conversion
date  of  the  Series  C  Preferred  Stock,  with  an  additional  25%  becoming
exercisable,  30,  60 and  90  days  following  the  first  exercise  date  on a
cumulative  basis. The holders of the Warrants are not entitled to any rights of
a stockholder  of the Company.  In addition,  the  Purchasers are entitled to an
adjustment in the exercise  price and/or the number of shares of Common Stock to
be received  upon  exercise of the Warrants in the event the Company  undertakes
certain  transactions  including  payment of  dividends  or  distributions  with
respect to its Common Stock,  subdivisions  or  combinations  of its outstanding
Common Stock and  recapitalizations in connection with a consolidation or merger
in which the Company is the continuing corporation.

      On February  5, 1997,  the Company  issued  15,000  shares of its Series D
Convertible Preferred Stock to P.R.I.F., L.P., in consideration for $15,000,000.
In  addition,  the Company  issued  warrants to purchase up to 375,00  shares of

















                                      2


<PAGE>


Common  Stock  exercisable  at $6.00 per share on or prior to the June 30, 1998.
The Company is also  obligated  to issue  additional  warrants to purchase up to
100,000  shares of Common  Stock in the event  the  Company  undertakes  certain
additional  financings.  The exercise  price of all such  warrants is subject to
adjustments  in the  event of such  additional  financings.  The  funds  and the
Certificates  representing  the Series D Preferred  Stock and warrants have been
placed in escrow  pending  approval  by the  stockholders  of the Company at the
forthcoming  Annual Meeting of  Stockholders  to be held on February 28, 1997 of
the proposed Amendment to the Company's Certificate of Incorporation which would
increase the authorized Common Stock to seventy-five million shares. The Company
has also placed in escrow a  commitment  fee of $300,000  which would be paid to
P.R.I.F., L.P. in the event authorization is not obtained by the specified date.

      The Series D  Preferred  Stock (as  represented  by the  stated  value) is
convertible  into shares of Common  Stock of the Company by dividing  the stated
value of the Series D Preferred Stock to be converted by the conversion price in
effect at the time of conversion.  The  conversion  price shall be calculated at
18% discounted from the average closing bid price of the Company's Common Stock,
as reported by Bloomberg L.P., over the five-day trading period on the day prior
to conversion  (the  "Conversion  Price").  Notwithstanding  the foregoing,  the
Conversion  Price may not be more than $7.00 per share of Common  Stock nor less
than $2.00 per share of Common Stock (the "Floor"). In addition,  the holder may
not convert any Series D Preferred  Stock  during the  conversion  period if the
Conversion Price, averaged over any rolling consecutive five-day trading period,
falls  below the  Floor (a  "Non-Converting  Period").  Upon  occurrence  of the
twenty-first  Non-Converting  Period, the holder shall thereafter have the right
to convert,  but the Company  shall have the right to (i) pay to the holder cash
equal to the amount  originally paid by the holder for the outstanding  Series D
Preferred Stock to be converted plus 10% of such amount (the "Cash-Out Option"),
or (ii) convert the  outstanding  Series D Preferred Stock held by the holder to
be  converted  into the full amount of Common Stock to which the holder would be
entitled  at the  Conversion  Price  irrespective  of the  Floor.  Any  Series D
Preferred Stock remaining  outstanding on February 5, 1999 will be automatically
converted  into  Common  Stock of the  Company  on such date  subject to certain
limitations.  The holder of the Series D Preferred Stock may not convert his/her
shares if, as a result thereof, the shares of Common Stock beneficially owned by
the holder  will exceed 4.9% of the  outstanding  shares of Common  Stock of the
Company.

      The Series D Preferred  Stock provides for a cash dividend of 6% per annum
of the  stated  value of the Series D  Preferred  stock on a  cumulative  basis.
Dividends accrue from the date of issuance and are payable quarterly  commencing
March 31,  1997.  Except as  otherwise  provided by law, the holders of Series D
Preferred  stock do not have voting  rights.  Upon  liquidation,  dissolution or
winding-up of the Company,  no distribution may be made to the holders of shares
of capital stock ranking  junior to the Series D Preferred  Stock unless,  prior







                                        3


<PAGE>


thereto,  the holders of the Series D Preferred Stock shall have received $1,000
per share,  plus an amount equal to declared and unpaid dividends thereon to the
date of such payment.  A vote of not less than  two-thirds  of then  outstanding
shares  of  Series  D  Preferred  Stock  is  required  prior  to any  amendment,
alteration,  change  or  repeal  of any  of the  designations  of the  Series  D
Preferred Stock.

      The  proceeds  from the sale of the Series C and Series D Preferred  Stock
are expected to be used for the continued development of the Company's Omniferon
product including the funding of EU clinical trials,  completion of the Scottish
production  facility,  pre-clinical  Phase I and Phase II  trials  and Phase III
studies, the establishment of domestic  manufacturing  capacity,  joint research
and  development  projects,  product  development  research and general  working
capital purposes  including  administrative  support  functions and the possible
acquisition of one or more businesses complementary to the Company's operations.
The Company  has also agreed to file  separate  registration  statements  in the
proximate  future  covering the resale of shares of Common Stock  underlying the
aforementioned securities.

               CERTIFICATE OF DESIGNATIONS, PREFERENCES AND RIGHTS
                   OF THE SERIES C CONVERTIBLE PREFERRED STOCK
                                       OF
                                  VIRAGEN, INC.


      I, Gerald Smith,  President of Viragen,  Inc., a Delaware corporation,  DO
HEREBY CERTIFY:

      That  pursuant to the authority  conferred  upon the Board of Directors by
the  Articles of  Incorporation  of the  Corporation,  the Board of Directors on
December 5, 1996, adopted the following  resolutions creating a series of 20,000
Preferred  Shares,  $1.00  par  value  per  share,  designated  as the  Series C
Convertible Preferred Shares.

      The relative rights and preferences of the Series C Convertible  Preferred
Shares are as follows:

      1.  DESIGNATION AND AMOUNT.  The shares of such series shall be designated
as the Series C Convertible  Preferred Shares (the "Series C Preferred Shares"),
and the number of shares constituting such series shall be 20,000. The number of
shares  constituting  such series may,  unless  prohibited by the Certificate of
Incorporation,  be decreased by resolution  of the Board of Directors;  PROVIDED
that no  decrease  shall  reduce  the number of Series C  Preferred  Shares to a
number less than the number of shares then outstanding.

      2.    DIVIDENDS  AND  DISTRIBUTIONS.  The  holders  of Series C  Preferred
Shares shall not be entitled to receive any dividends.

      3.    VOTING RIGHTS.  Except as otherwise  provided by law, the holders of
Series C Preferred  Shares shall have no voting  rights and their  consent shall
not be required  (except to the extent required by law) for taking any corporate
action.

      4. REACQUIRED SHARES. Any Series C Preferred Shares purchased or otherwise
acquired by the Corporation in any manner whatsoever shall constitute authorized
but  unissued  preferred  shares and may be  reissued as part of a new series of
preferred shares by resolution or resolutions of the Board of Directors, subject
to the  conditions  and  restrictions  on  issuance  set  forth  herein,  in the
Certificate  of  Incorporation,  or in  any  other  Certificate  of  Designation
creating a series of preferred shares or as otherwise required by law.

      5.    LIQUIDATION,  DISSOLUTION  OR  WINDING  UP.  Upon  any  liquidation,
dissolution or winding up of the Corporation,  no distribution  shall be made to
the holders of shares of stock ranking junior (upon liquidation,  dissolution or
winding up) to the Series C Preferred Shares unless,  prior thereto, the holders




<PAGE>


of Series C  Preferred  Shares  shall have  received  $1,000 per share,  plus an
amount  equal to declared and unpaid  distributions  thereon to the date of such
payment.  The Series C Preferred Shares are subordinated to the Company's Series
B Convertible  Preferred  Shares  solely upon any  liquidation,  dissolution  or
winding up of the Company.

      6. CONSOLIDATION,  MERGER,  EXCHANGE,  ETC.. In case the Corporation shall
enter into any consolidation,  merger, combination,  statutory share exchange or
other  transaction  in which the Common Shares are exchanged for or changed into
other stock or  securities,  money and/or any other  property,  then in any such
case the Series C preferred shares shall at the same time be similarly exchanged
or changed into preferred  shares of the surviving  entity providing the holders
of such preferred  shares with (to the extent possible) the same relative rights
and preferences as the Series C Preferred Shares.

      7.    CONVERSION.

            (a) At the option of the holder of the Series C Preferred Shares, up
to  twenty-five  (25%)  percent of the Series C  Preferred  Shares  held by such
holder  may be  convertible,  on or after ten days from the date the  underlying
Common Shares have been registered with the Securities  Exchange  Commission for
public sale (the "Effective Date"), into shares of the Company's Common Stock on
the basis of one share of Series C Preferred  Shares for shares of Common  Stock
equal in number to the amount determined by dividing $1,000 by the Closing Price
of the Corporation's Common Shares.  Thereafter, an additional twenty-five (25%)
percent of the  Preferred  Shares shall be  convertible  on or after each of the
30th,  60th and 90th days  thereafter on a cumulative  basis.  The term "Closing
Price" is defined as the average closing price of the Corporation  Common Shares
over the five-day  trading  period ending on the day prior to the  conversion of
the Series C Preferred Shares.  Notwithstanding  the above, the conversion price
may not be less than $3.46 nor more than $7.00.  Any Series C  Preferred  Shares
which are  outstanding on the first  anniversary of the Closing for the offering
of the Series C Preferred Shares will be automatically  converted into shares of
the Corporation's Common Stock as provided above.

            (b) In the  event  the  Corporation  shall  at any time  after  such
Closing  declare or pay any dividend on Common Shares  payable in Common Shares,
or effect a subdivision  or  combination  or  consolidation  of the  outstanding
Common Shares (by reclassification or otherwise) into a greater or lesser number
of Common  Shares,  then in each such case the number of Common Shares  issuable
upon the  conversion  of the Series C Preferred  Shares shall be  determined  as
follows:









                                      2


<PAGE>


      X           $       
    -----       ------     Shares of Common Stock Issuable Upon
      Y    x    % x CP  = Conversion of Preferred Stock

      X     =     the number of Common Shares outstanding immediately after such
                  event

      Y     =     The   number   of   Common   Shares   that  were   outstanding
                  immediately prior to such event.

      $     =     $1,000

      %     =     100%

      CP    =     Closing Price, as defined in Section 7(a)

      Notwithstanding  the above,  the conversion price (% x CP) may not be less
than $3.46 nor more than $7.00.

      (c) The foregoing notwithstanding, in the event the conversion price would
be less than $3.46 but for such minimum conversion price, the difference between
$3.46 and what the  conversion  price  would have been  except for such  minimum
price,  multiplied by the number of shares issued  conversion,  shall be paid to
the holder in cash upon conversion.

      8.    VOTE TO CHANGE THE TERMS OF SERIES C PREFERRED SHARES.

      The  approval  of the Board of  Directors  and the  affirmative  vote at a
meeting duly called by the Board of  Directors  for such purpose (or the written
consent without a meeting) of the holders of not less than  two-thirds  (2/3) of
the then  outstanding  Series C  Preferred  Shares  shall be  required to amend,
alter, change or repeal any of the powers, designations,  preferences and rights
of the Series C Preferred Shares.

      IN WITNESS  WHEREOF,  I have executed this  Certificate  of  Designations,
Preferences and Rights this 5th day of December, 1996.

              CERTIFICATE OF DESIGNATIONS, PREFERENCES AND RIGHTS
                  OF THE SERIES D CONVERTIBLE PREFERRED STOCK
                                      OF
                                 VIRAGEN, INC.


      I, Gerald Smith,  President of Viragen,  Inc., a Delaware corporation,  DO
HEREBY CERTIFY:

      That  pursuant to the authority  conferred  upon the Board of Directors by
the Certificate of Incorporation  of the Corporation,  the Board of Directors on
November 8, 1996, adopted the following  resolutions creating a series of 15,000
Preferred  Shares,  $1.00 par value per share,  stated  value  $1,000 per share,
designated as the Series D Convertible Preferred Shares.

      The relative rights and preferences of the Series D Convertible  Preferred
Shares are as follows:

      1.  DESIGNATION AND AMOUNT.  The shares of such series shall be designated
as the Series D Convertible  Preferred Shares (the "Series D Preferred Shares"),
and the number of shares  constituting such series shall be 15,000 and shall not
be subject to  increase.  The number of shares  constituting  such  series  may,
unless  prohibited  by  the  Certificate  of  Incorporation,   be  decreased  by
resolution of the Board of Directors; PROVIDED that no decrease shall reduce the
number of Series D  Preferred  Shares to a number less than the number of shares
then outstanding.

      2. DIVIDENDS AND  DISTRIBUTIONS.  The holders of Series D Preferred Shares
shall be entitled  to receive a dividend  of six  percent  (6%) per annum of the
stated value of the Series D Preferred Shares, to accrue commencing  February 5,
1997 and payable quarterly in arrears, in cash,  commencing March 31, 1997. Upon
conversion,  any accrued but unpaid  dividends will be added to the stated value
of the Series D Preferred Shares converted.

      3. VOTING  RIGHTS.  Except as  otherwise  provided by law,  the holders of
Series D Preferred  Shares shall have no voting  rights and their  consent shall
not be required  (except to the extent required by law) for taking any corporate
action.

      4. REACQUIRED SHARES. Any Series D Preferred Shares purchased or otherwise
acquired by the Corporation in any manner whatsoever shall constitute authorized
but  unissued  preferred  shares and may be  reissued as part of a new series of
preferred shares by resolution or resolutions of the Board of Directors, subject
to the  conditions  and  restrictions  on  issuance  set  forth  herein,  in the
Certificate  of  Incorporation,  or in  any  other  Certificate  of  Designation
creating a series of preferred shares or as otherwise required by law.








<PAGE>



      5.   LIQUIDATION,   DISSOLUTION  OR  WINDING  UP.  Upon  any  liquidation,
dissolution or winding up of the Corporation,  no distribution  shall be made to
the holders of shares of stock ranking junior (upon liquidation,  dissolution or
winding up) to the Series D Preferred Shares unless,  prior thereto, the holders
of Series D  Preferred  Shares  shall have  received  $1,000 per share,  plus an
amount  equal to  declared  and  unpaid  dividends  thereon  to the date of such
payment. The Series D Preferred Shares shall rank junior to the Company's Series
B Convertible  Preferred  Shares  solely upon any  liquidation,  dissolution  or
winding up of the Company, and no amount shall be paid to any holder of Series D
Preferred  Shares in connection  therewith unless all amounts payable to holders
of the Company's Series B Convertible Preferred Shares have been paid in full.

      6. CONSOLIDATION,  MERGER,  EXCHANGE,  ETC.. In case the Corporation shall
enter into any consolidation,  merger, combination,  statutory share exchange or
other  transaction  in which the Common Shares are exchanged for or changed into
other stock or  securities,  money and/or any other  property,  then in any such
case the Series D preferred shares shall at the same time be similarly exchanged
or changed into preferred  shares of the surviving  entity providing the holders
of such preferred  shares with (to the extent possible) the same relative rights
and preferences as the Series D Preferred Shares.

      7.    CONVERSION.

            (i) The Series D Preferred  Shares will be convertible at the option
of the holder or holders  (the  "Holders"),  on or after the  earlier of (x) the
date which is 30 days after the Series D  Preferred  Shares are  delivered  from
escrow to the initial  holder  thereof and (y) the date  following the date that
the  registration  statement  for the  shares of Common  Stock,  $.01 par value,
underlying the Series D Preferred Shares (the "Common Shares") has been declared
effective by the Securities and Exchange  Commission (the "Conversion  Period"),
by dividing the stated value of the Series D Preferred  Stock to be converted by
the conversion  price,  which shall be calculated at eighteen  percent (18%) off
the average closing bid price of the Corporation's  Common Stock, as reported by
Bloomberg,  L.P.,  over the five-day  trading  period ending on the day prior to
conversion (the "Conversion  Price").  Notwithstanding the above, the Conversion
Price may not be more than Seven Dollars  ($7.00) U.S. per Common Share nor less
than Two Dollars ($2.00) U.S. per Common Share (the "Floor"); provided, however,
that the  Holder  may not  convert  any  Series D  Preferred  Shares  during the
Conversion Period if the Conversion Price, averaged over any rolling consecutive
5-day trading  period,  falls below the Floor (each such period of 5 consecutive
days so used for determining such average being a "Nonconverting  Period"). Upon
occurrence of the twenty-first Nonconverting Period, the Holder shall thereafter
have the right to convert and the Corporation will be obligated, upon receipt of
a notice of  conversion  from the Holder to effect  such  conversion;  provided,
however,  that if the  Conversion  Price would be below the Floor,  the Company,
shall  have  the  right  to (a)  pay to the  Holder  cash  equal  to the  amount







                                        2


<PAGE>


originally paid by the Holder for the outstanding  Series D Preferred  Shares to
be converted plus ten percent (10%) of such amount (the "Cash-Out  Option"),  or
(b) convert the outstanding  Series D Preferred  Shares held by the Holder to be
converted  into the full  number of Common  Shares to which the Holder  would be
entitled  at the  Conversion  Price,  irrespective  of  the  Floor  (the  "Stock
Conversion  Option").  The Corporation must notify the Holder of its intent with
regard to such  options  within one (1) business day of receipt of the notice of
conversion,  and must effect such cash payment or stock conversion  within three
(3) business days of receipt of the notice of conversion.

            (ii) Any Series D  Preferred  Shares  remaining  outstanding  on the
second  anniversary  of the  issuance of the Series D  Preferred  Shares will be
automatically  converted  into  Common  Shares  on  such  date,  subject  to the
limitation of Section 7 (vi) hereof.  The Series D Preferred Shares shall have a
liquidation  preference over the Common Shares in the event of any  liquidation,
dissolution or winding up of the Corporation or the sale of the Corporation.

            (iii) In  connection  with any  conversion of the Series D Preferred
Shares by a Holder or in the event the Corporation  elects the Stock  Conversion
Option as defined in Section 7(i) above, the Corporation shall issue and deliver
to the Holder an unlegended certificate or certificates for the number of Common
Shares to which the Holder shall be entitled within three (3) business days (the
"Deadline")  after receipt by the  Corporation  of the duly  executed  notice of
conversion and the original Series D Preferred Shares being  converted,  with an
executed stock power. The Holder understands that a delay in the issuance of the
Common Shares  beyond the Deadline  could result in economic loss to the Holder.
As  compensation  to the  Holder  for  such  loss,  and  not as a  penalty,  the
Corporation  agrees to pay liquidated damages to the Holder for late delivery of
Common Shares upon conversion in the amount of one percent (1%) of the requested
conversion amount, per day, beginning on the fourth (4th) business day after the
Deadline  in the event the  Common  Shares  are not  received  within  seven (7)
business days after said Deadline. Said liquidated damages shall accrue each day
through the date the Common Shares are delivered to the Holder upon  conversion,
and shall be paid by wire  transfer to an account  designated by the Holder upon
the earlier to occur of (i) delivery of the Common  Shares to the Holder or (ii)
each  weekly  anniversary  of the  Deadline.  Nothing  herein  shall  waive  the
Corporation's obligations to deliver Common Shares upon conversion of the Series
D Preferred  Shares or limit the Holder's right to pursue actual damages for the
Corporation's  failure  to issue and  deliver  Common  Shares  to the  Holder in
accordance with the terms of the Series D Preferred Shares.

            (iv) The Corporation  agrees that, in addition to any other remedies
which may be available to the Holder in the event the Corporation  fails for any
reason to effect delivery to the Holder of unlegended certificates  representing
Common  Shares  within  seven  (7)  business  days  following   receipt  by  the
Corporation  of notice of  conversion,  the  Holder  may  revoke  the  notice of



                                      3


<PAGE>


conversion by delivering a notice to such effect to the  Corporation,  whereupon
the  Corporation  and the Holder  shall  each be  restored  to their  respective
positions immediately prior to delivery of such notice of conversion.

            (v) In the event the Corporation shall at any time after issuance of
the Series D  Preferred  Stock  declare  or pay any  dividend  on Common  Shares
payable  in  Common   Shares,   or  effect  a  subdivision   or  combination  or
consolidation  of  the  outstanding  Common  Shares  (by   reclassification   or
otherwise)  into a greater or lesser number of Common Shares,  then in each such
case the number of Common Shares  issuable  upon the  conversion of the Series D
Preferred Shares shall be determined as follows:

              X           $     
            ----        ------     Shares of Common Stock Issuable Upon
              Y    x    % x CP  = Conversion of Series D Preferred Stock

      X     =     the number of Common Shares outstanding immediately after such
                  event

      Y     =     The   number   of   Common   Shares   that  were   outstanding
                  immediately prior to such event.

      $     =     $1,000

      %     =     100%

      CP    =     Conversion Price, as defined in Section 7(i)

      Notwithstanding  the above,  the conversion price (% x CP) may not be less
than $2.00 nor more than $7.00 except as otherwise provided in Section 7(i).

            (vi) Notwithstanding any other provision of this Certificate,  in no
event shall any holder of Series D  Preferred  Shares be entitled to any time to
convert any Series D Preferred Shares (and accrued and unpaid dividends thereon)
in excess of that  number of Series D Preferred  Shares (and  accrued and unpaid
dividends  thereon) upon conversion of which the sum of (1) the number of Common
Shares  beneficially  owned  by such  holder  and any  person  whose  beneficial
ownership of Common  Shares would be aggregated  with such  holder's  beneficial
ownership  of Common  Shares for  purposes  of Section  13(d) of the  Securities
Exchange  Act of 1934,  as  amended  (the  "1934  Act"),  and  Regulation  13D-G
thereunder  (each a  "Restricted  Holder")  (other than  shares of Common  Stock
deemed  beneficially  owned  through  the  ownership  of  unconverted  Series  D
Preferred  Shares and  accrued  and unpaid  dividends  thereon  and  through the
ownership  of  unexercised  warrants to purchase  Common  Shares  which  contain
limitations  similar to this Section  7(vi) and (2) the number of Common  Shares
issuable upon conversion of the number of Series D Preferred  Shares and accrued
and unpaid  dividends  thereon with respect to which the  determination  in this






                                     4


<PAGE>


Section  7(vi) is being  made,  would  result in  beneficial  ownership  by such
Restricted  Holder of more  than  4.9% of the  outstanding  Common  Shares.  For
purposes of the immediately  preceding sentence,  beneficial  ownership shall be
determined  in  accordance  with Section  13(d) of the 1934 Act, and  Regulation
13D-G thereunder,  except as otherwise provided in clause (1) of the immediately
preceding sentence.

      8.    VOTE TO CHANGE THE TERMS OF SERIES D PREFERRED SHARES.

      The  approval  of the Board of  Directors  and the  affirmative  vote at a
meeting duly called by the Board of  Directors  for such purpose (or the written
consent without a meeting) of the holders of not less than  two-thirds  (2/3) of
the then  outstanding  Series D  Preferred  Shares  shall be  required to amend,
alter, change or repeal any of the powers, designations,  preferences and rights
of the Series D Preferred Shares.

      IN WITNESS  WHEREOF,  I have executed this  Certificate  of  Designations,
Preferences and Rights this ____ day of January, 1997.

                              VIRAGEN, INC./[BUYER]

                                                              December 31, 1996


      THIS  PRIVATE   SECURITIES   SUBSCRIPTION   AGREEMENT   (hereinafter   the
"Agreement") has been executed by the undersigned in connection with the sale in
a private  placement  pursuant to Section 4(2) of the Securities Act of 1933, as
amended  (the  "Securities  Act"),  of  certain  shares of Series C  Convertible

Delaware (hereinafter "SELLER") to [BUYER],  located at [ADDRESS], a corporation
organized  under the laws of [INCORP]  (hereinafter  "BUYER").  SELLER and BUYER
(hereinafter  collectively the "parties") each hereby  represents,  warrants and
agrees as follows:


1.    AGREEMENT TO SUBSCRIBE; PURCHASE PRICE

      (i)  SELLER and BUYER are  executing  and  delivering  this  Agreement  in
reliance upon the exemption from  securities  registration  afforded by Rule 506
under  Regulation  D  ("Regulation  D")  as  promulgated  by the  United  States
Securities and Exchange Commission under the Securities Act; and

      (ii) BUYER hereby  subscribes for Three Hundred (300) Preferred Shares, at

2.    BUYER'S REPRESENTATIONS AND AGREEMENTS

      BUYER represents, warrants and agrees as follows:

      (i) BUYER understands that the Preferred Shares, Warrants,  Common Shares,
and the Warrant Shares have not been registered under the Securities Act, or any
other applicable securities law, and, accordingly, none of the Preferred Shares,
Warrants,  Common Shares or Warrant  Shares may be offered,  sold,  transferred,
pledged, hypothecated or otherwise disposed of unless registered pursuant to, or
in a transaction  exempt from  registration  under,  the  Securities Act and any
other applicable securities law;

      (ii)  BUYER  is an  "accredited  investor"  within  the  meaning  of  Rule
501(a)(1),  (2), (3), or (7) of Regulation D (an "Accredited  Investor") that is
acquiring  the Shares  either for its own account or as a fiduciary or agent for
one or more  institutional  accounts as to which it exercises  sole  discretion,
each of which is an Accredited Investor. BUYER has such knowledge and experience
in financial and business  matters that it is capable of  evaluating  the merits
and risks of an investment in the Shares. BUYER has had a reasonable opportunity
to ask questions of and receive  answers from SELLER  concerning  SELLER and the
offering of the Shares and Warrants. BUYER is not subscribing for the Shares and
Warrants as a result of or pursuant to any  advertisement,  article,  notice, or
other communication  published in any newspaper,  magazine,  or similar media or
broadcast  over   television  or  radio.   BUYER  is  aware  that  it  (or  such
institutional  account)  may  be  required  to  bear  the  economic  risk  of an
investment in the Shares for an indefinite period, and it (or such institutional
account ) is able to bear such risk for an indefinite period;

      (iii) BUYER is acquiring the  Preferred  Shares,  Warrants and  underlying
Shares  for  its  own  account  or for one or  more  institutional  accounts  as
described in Paragraph  2(ii) hereof,  in each case for investment  purposes and
not with a view to, or for offer or sale in connection  with,  any  distribution
thereof  (subject to any requirement of law that the disposition of its property
or the property of such  institutional  account or accounts remain within its or
their  control).  BUYER  agrees  on its own  behalf  and on  behalf  of any such
institutional  account  for  which it is  acquiring  the  Preferred  Shares  and
Warrants to offer, sell or otherwise  transfer any Preferred Shares and Warrants
only to  Accredited  Investors  (subject  to any  requirement  of law  that  the
disposition  of its  property or the property of such  institutional  account or
accounts  remain within its or their control) in conformity  with the Securities
Act and any  other  applicable  securities  law and  with  the  restrictions  on
transfer  set  forth  on the  certificates  evidencing  such  securities.  BUYER
acknowledges  that each  certificate  evidencing  such  securities  shall bear a
legend  substantially  to the effect of the foregoing  paragraphs 2(i) and 2(ii)
and this paragraph  2(iii).  Such legend shall be in substantially the following
form:

      THE  SECURITIES  EVIDENCED BY THIS  CERTIFICATE  HAVE NOT BEEN  REGISTERED
      UNDER THE  SECURITIES  ACT OF 1933 (THE  "ACT")  AND MAY NOT BE OFFERED OR
      SOLD, TRANSFERRED,  PLEDGED,  HYPOTHECATED OR OTHERWISE DISPOSED OF EXCEPT
      PURSUANT TO AN EFFECTIVE  REGISTRATION STATEMENT UNDER THE ACT OR PURSUANT
      TO AN  AVAILABLE  EXEMPTION  FROM SUCH  REGISTRATION.  THE  HOLDER OF THIS
      CERTIFICATE IS THE  BENEFICIARY OF CERTAIN  OBLIGATIONS OF THE COMPANY SET
      FORTH IN A PRIVATE SECURITIES  SUBSCRIPTION  AGREEMENT BETWEEN THE COMPANY
      AND  [BUYER]  DATED  [DATE].  A COPY  OF  THE  PORTION  OF  THE  AFORESAID
      SUBSCRIPTION  AGREEMENT  EVIDENCING SUCH  OBLIGATIONS MAY BE OBTAINED FROM
      THE COMPANY'S EXECUTIVE OFFICES.

<PAGE>

      Upon conversion of the Preferred Shares, SELLER shall issue a common stock
certificate  without such legend to the holder of such shares if (a) such Shares
are sold pursuant to an effective  registration  statement  under the Securities
Act, or (b) such holder  provides  SELLER with an opinion of counsel  reasonably
acceptable  to SELLER to the effect  that a public  sale or a  transfer  of such
security may be made without  registration under the Securities Act, or (c) such
holder provides SELLER with reasonable assurances that such security can be sold
free of any volume limitations pursuant to Rule 144 under the Securities Act (or
a successor thereto).

      (iv)  BUYER   acknowledges   that  each   Warrant   shall  bear  a  legend
substantially to the effect of the foregoing  paragraphs 2(i) and 2(ii) and this
paragraph 2(iv). Such legend shall be in substantially the following form:

      NEITHER  THIS  WARRANT NOR ANY SHARES OF COMMON  STOCK  ISSUABLE  UPON THE
      EXERCISE OF THIS WARRANT HAVE BEEN REGISTERED  UNDER THE SECURITIES ACT OF
      1933, AS AMENDED,  AND THE RULES AND  REGULATIONS  PROMULGATED  THEREUNDER
      (THE  "SECURITIES  ACT").  THIS WARRANT AND THE COMMON STOCK ISSUABLE UPON
      EXERCISE  OF  THIS  WARRANT  MAY  NOT  BE  OFFERED,   SOLD,  OR  OTHERWISE
      TRANSFERRED  IN THE ABSENCE OF  REGISTRATION  UNDER THE  SECURITIES ACT OR
      SUCH OFFER, SALE OR TRANSFER IS EXEMPT FROM SUCH REGISTRATION.

      Upon  exercise  of  the  Warrant,   SELLER  shall  issue  a  common  stock
certificate without such legend to the holder of such Warrant if (a) the Warrant
Shares  are sold  pursuant  to an  effective  registration  statement  under the
Securities  Act, or (b) such holder  provides  SELLER with an opinion of counsel
reasonably  acceptable  to SELLER to the effect that a public sale or a transfer
of such security may be made without  registration  under the Securities Act, or
(c) such holder provides SELLER with reasonable assurances

that such security can be sold free of any volume  limitations  pursuant to Rule
144 under the Securities Act (or a successor thereto).

       (v) BUYER  acknowledges that SELLER or any transfer agent of SELLER shall
register  the  transfer or exchange of any of the  Preferred  Shares or Warrants
only upon receipt of the respective (A)  certificates  evidencing such Preferred
Shares with the transfer notice set forth thereon  appropriately  completed,  or
(B) the  Warrants,  and upon  receipt  in  writing  from the  transferee  or the
recipient of such Preferred  Shares or Warrants in such transfer or exchange (as
the case may be) of a certificate setting forth the representations in Paragraph
2 hereof;

      (vi)  If  BUYER  is  acquiring  any  Preferred  Shares,  Warrants  or  the
underlying Shares as fiduciary or agent for one or more institutional  accounts,
BUYER  represents  that it has sole  investment  discretion with respect to each
such account and that it has full power to make the  foregoing  acknowledgments,
representations and agreements on behalf of each such institutional account;

      (vii) BUYER  acknowledges  that SELLER and others will rely upon the truth
and accuracy of the foregoing  acknowledgments,  representations  and agreements
and further agrees that if, prior to the closing,  any of such  acknowledgments,
representations and agreements made by BUYER are no longer accurate,  BUYER will
promptly notify SELLER;

<PAGE>

      (viii) BUYER has received  all  information  necessary to make an informed
business  decision  with  respect  to an  investment  in the  Preferred  Shares,
Warrants and  underlying  Shares,  including but not limited to SELLER'S  latest
Form 10-K, all Forms 10-Q and 8-K filed thereafter,  and the Proxy Statement for
its latest fiscal year  (collectively,  the "Public  Documents") and the Private
Placement  Memorandum  prepared by SELLER.  Neither the Public Documents nor the
Private Placement  Memorandum include any untrue statement of a material fact or
omit to state  any  material  fact  necessary  in  order to make the  statements
contained therein, in light of the circumstances under which they were made, not
misleading;

      (ix)  This  Agreement  has been duly  authorized,  validly  executed,  and
delivered on behalf of BUYER and is a valid and binding agreement enforceable in
accordance  with its  terms,  subject  to  general  principles  of equity and to
bankruptcy  or  other  laws  affecting  the  enforcement  of  creditors'  rights
generally; and


      (x) BUYER has not  engaged  and agrees not to engage in any short sales or
other  hedging  transactions  with respect to SELLER'S  common  stock;  provided
however,  that  BUYER may enter  into such  transactions  involving  a number of
common  shares not to exceed the number of Common  Shares or Warrant  Shares for
which a Notice  of  Conversion  or  Election  to  Purchase  with  regard  to the
Preferred Shares or Warrants, respectively, has been submitted to SELLER.



3.    SELLER'S REPRESENTATIONS AND AGREEMENTS

SELLER represents, warrants and agrees as follows:

       (i)  SELLER  has not  conducted  any  general  solicitation  or general
advertising  (as  defined  in  Regulation  D)  with  respect  to  any  of  its
securities;

      (ii) The Preferred Shares, the Warrants,  and the Shares,  when issued and
delivered,  will be duly and  validly  authorized  and  issued,  fully-paid  and
nonassessable, and will not subject the holders thereof to personal liability by
reason of being such holders. In addition,  the Preferred Shares,  Warrants, and
Shares,  when  issued  and  delivered,  shall  be free and  clear of any  liens,
encumbrances,  charges, or adverse claims of any nature whatsoever. There are no
preemptive  rights of any  shareholder  of SELLER with respect to the  Preferred
Shares, Warrants, and the Shares;

      (iii)  This  Agreement  has been duly  authorized,  validly  executed  and
delivered on behalf of SELLER and is a valid and binding agreement in accordance
with its terms,  subject to general  principles  of equity and to  bankruptcy or
other laws affecting the enforcement of creditors' rights generally;

      (iv) The execution and delivery of this Agreement and the  consummation of
the issuance of the  Preferred  Shares,  the Warrants,  and the Shares,  and the
transactions contemplated by this Agreement do not and will not conflict with or
result in a breach by SELLER of any of the terms or provisions of, or constitute
a default under, the articles of incorporation (or charter) or bylaws of SELLER,


<PAGE>

or any  indenture,  mortgage,  deed of  trust  or other  material  agreement  or
instrument to which SELLER is a party or by which it or any of its properties or
assets are bound, or any existing  applicable  decree,  judgment or order of any
court,  federal  or  state  regulatory  body,  administrative  agency  or  other
governmental  body having  jurisdiction  over SELLER or any of its properties or
assets;

      (v) No  authorization,  approval or consent of or filing with any federal,
state or local  governmental  body of the United States is legally  required for
the issuance and sale of the Shares as contemplated by this Agreement;

      (vi) The  information  provided  by or on  behalf  of  SELLER to BUYER and
referred  to in Section  2(viii) of this  Agreement  does not contain any untrue
statement  of a material  fact or omit to state any material  fact  necessary in
order to make the statements  therein,  in the light of the  circumstance  under
which they are made,  not  misleading.  Since June 30,  1996,  there has been no
material adverse development in the business, properties,  operations, financial
condition  or  results  of  operations  of Seller,  except as  disclosed  in the
documents referred to in Section 2(viii) hereof.

      (vii)  SELLER  will  issue  one  or  more  certificates  representing  the
Preferred  Shares in the name of BUYER in such  denominations to be specified by
BUYER prior to closing.  The Preferred  Shares will bear the restrictive  legend
specified in Section 2(iii) of this Agreement.  SELLER further  warrants that no
instructions  other than these  instructions  and stop transfer  instructions to
give effect to Section 2(i) hereof will be given to the transfer  agent and also
warrants  that the  Shares  shall  otherwise  be  transferable  on the books and
records of SELLER as and to the extent  provided in this  Agreement,  subject to
compliance with Federal and State securities laws. Nothing in this Section shall
affect  in any  way  BUYER'S  obligations  and  agreement  to  comply  with  all
applicable securities laws upon resale of the Shares.

      (viii) Prior to Closing, SELLER will issue a Common Stock Purchase Warrant
Certificate  entitling BUYER to purchase one (1) common share for every four (4)
Common Shares that BUYER would have  received had BUYER  converted the Preferred
Shares at Closing.  The Common Stock Preferred Warrant Certificate will bear the
restrictive legend specified in Section 2(iv) of this Agreement.  SELLER further
warrants that no instructions  other than these  instructions  and stop transfer
instructions to give effect to Section 2(i) hereof will be given to the transfer
agent and also warrants that the Shares shall  otherwise be  transferable on the
books and  records of SELLER as and to the extent  provided  in this  Agreement,
subject to compliance with Federal and State  securities  laws.  Nothing in this
Section shall affect in any way BUYER'S obligations and agreement to comply with
all applicable securities laws upon resale of the Shares.

4. THIRD PARTY  BENEFICIARY.  The parties  acknowledge  and agree that Shoreline
Pacific,  the  Institutional   Division  of  Financial  West  Group  ("Shoreline
Pacific"),  shall be deemed a third party beneficiary of SELLER'S agreements and
representations  set forth in this  Agreement,  entitled  to  enforce  the terms
thereof,  and to indemnification  for any damages resulting to Shoreline Pacific
from any  actual or  threatened  breach  thereof by  SELLER,  both in  Shoreline
Pacific's personal capacity and, should Shoreline Pacific so elect, on behalf of
BUYER.


<PAGE>

5.    CLOSING.  Preferred Share  certificates  and Warrants shall be delivered
to BUYER and the funds  therefor  shall be  delivered to SELLER on [DATE] (the
"Closing") or at such time to be mutually agreed by the parties.

6.    CONDITIONS TO CLOSING

      (i)...BUYER  understands  that  SELLER'S  obligation to sell the Preferred
Shares and to issue the Warrants is  conditioned  upon delivery into escrow,  or
otherwise as agreed  between BUYER and SELLER,  by BUYER of the amount set forth
in Paragraph 1 hereof.

      (ii)..SELLER understands that BUYER'S obligation to purchase the Preferred
Shares is conditioned  upon delivery of certificates  representing the Preferred
Shares  as  described  in  Paragraph  1(ii) and the  Warrants  as  described  in
Paragraph  1(iv),  and upon  provision of an opinion of counsel  confirming  the
matters set out in Section 3(ii), (iii), (iv) and (v) above. With respect to the
opinion of counsel  concerning Section 3(iv), said opinion shall be qualified as
to the best of counsel's knowledge, except with respect to conflicts or defaults
under SELLER'S Articles of Incorporation and/or Bylaws.

      (iii) SELLER understands that BUYER'S obligation to purchase the Preferred
Shares  and  Warrants  is  conditioned  upon  SELLER and BUYER  entering  into a
Registration Rights Agreement substantially in the form of Annex I hereto.


7.  GOVERNING  LAW;  INTERPRETATION.  This  Agreement  shall be  governed by and
interpreted in accordance  with the laws of the State of New York without giving
effect to rules  governing the conflict of laws. The parties  jointly consent to
personal  jurisdiction  in any state or  federal  court  located in the state of
California,  waive any objection as to jurisdiction  or venue,  and agree not to
assert any defense based on lack of jurisdiction or venue.  Facsimile signatures
of this Agreement shall be binding on all parties hereto.


8. CONVERSION. SELLER shall use its best efforts to issue and deliver to BUYER a
certificate or certificates for the number of Common Shares to which BUYER shall
be  entitled  within  seven (7)  business  days after  BUYER has  fulfilled  all
conditions  required  for  conversion  as  set  forth  in  this  Agreement  (the
"Deadline").  SELLER  understands  that a delay in the  issuance  of the  Common
Shares  beyond  the  Deadline  could  result  in  economic  loss  to  BUYER.  As
compensation to BUYER for such loss, and not as a penalty,  SELLER agrees to pay
liquidated  damages to BUYER for late issuance of Common Shares upon conversion,
or  exercise,  in the amount of one  percent  (1%) of the  requested  conversion
amount,  per day,  beginning on the eighth  (8th)  business day from the date of
receipt by SELLER of a duly executed notice of conversion or exercise,  provided
that the original Preferred Shares to be converted,  or Warrants to be exercised
have been  delivered to SELLER within such time period,  all in accordance  with
this  Agreement,  the Preferred  Shares or the Warrants,  respectively,  and the
requirements of SELLER'S  transfer agent.  Said liquidated  damages shall accrue
each day through the date the Common

<PAGE>

Shares are issued to BUYER upon  conversion  or  exercise,  and shall be paid by
wire transfer to an account designated by BUYER upon the earlier to occur of (i)
issuance of the Shares to BUYER, or (ii) each monthly anniversary of the receipt
by SELLER of such BUYER'S  notice of conversion  or exercise.  In the event that
SELLER has taken all steps  reasonably  necessary to effect such  conversion  or
exercise, but due to circumstances  completely and totally beyond the control of
SELLER, such conversion has not taken place by the Deadline, then the liquidated
damages referred to above shall not begin to accrue until the fifteenth business
day after receipt by SELLER of the duly executed  Notice of Conversion.  Nothing
herein shall waive SELLER'S obligations to deliver Common Shares upon conversion
of the Preferred  Shares or limit  BUYER'S  right to pursue  actual  damages for
SELLER'S  failure to issue and deliver Common Shares to BUYER in accordance with
the terms of this Agreement and the Preferred Shares.

SELLER agrees that, in addition to any other  remedies which may be available to
BUYER,  in the event SELLER fails for any reason to effect  delivery to Buyer of
certificates representing Common Shares within seven (7) business days following
receipt  by SELLER of a notice of  conversion,  BUYER may  revoke  the notice of
conversion by delivering a notice of such effect to SELLER, whereupon SELLER and
BUYER shall each be restored to their respective positions  immediately prior to
delivery of such notice of conversion.


IN WITNESS  WHEREOF,  this Agreement was duly executed on the date first written
above.

            2.    REGISTRATION.


            (A)  PAYMENTS BY THE COMPANY.  The Company must file a  Registration
      Statement  with  the SEC  within  20  business  days of the  last  Closing
      registering the Common Stock  underlying the Preferred Shares and Warrants
      for  resale.   The  Company  shall  use  its  best  efforts  to  have  the
      Registration  Statement  declared  effective  as  soon as  possible  after
      filing. If the Registration  Statement covering the Registrable Securities
      is not effective within 110 days after the last Closing,  then the Company
      will make  payments to Buyer in such amounts and at such times as shall be
      determined  pursuant to this  Section  2(a).  The amount to be paid by the
      Company  to the  Buyer  shall be a use of funds  fee  equal to 1/2% of the
      subscription  price for the first and second months following said 110-day
      period,  which  use of funds  fee  shall  be  prorated  on a daily  basis.
      Thereafter,  the  Company  shall pay a penalty to Buyer equal to 2% of the
      subscription  price for each month,  prorated on a daily basis,  until the
      Registration  Statement  is declared  effective  by the SEC.  Said penalty
      shall not exceed the maximum amount  allowed by law. The amounts  referred
      to in this section shall be paid by the Company  within five business days
      after the end of the  applicable  month  beginning  with the 30 day period
      beginning on the first day following the 110-day period  referred to above
      and shall be payable in cash;  provided,  however,  that the  Company  may
      elect in lieu of  payment  of any such  amount in cash to  deliver  to the
      Initial  Investor shares of Common Stock having an Aggregate  Market Value
      equal to the  amount of the  Periodic  Amount  if,  but only if,  (1) such
      shares are freely tradable by the Initial Investor without any restriction
      under the Securities Act or any state securities or "blue sky" law and (2)
      after the issuance of such shares to the Holder,  the aggregate  number of
      shares of Common Stock  beneficially  owned by the Holder  (determined  in
      accordance  with  Section  13(d) of, and  Regulations  13 D-G  under,  the
      Securities  Exchange Act of 1934, as amended (the  "Exchange  Act")) would
      not exceed 4.9% of the outstanding shares of Common Stock.

<PAGE>

            (B)  PIGGY-BACK  REGISTRATIONS.  If at any  time the  Company  shall
      determine  to  prepare  and  file  with the SEC a  Registration  Statement
      relating to an offering for its own account or the account of others under
      the Securities Act any of its equity securities, other than on Form S-4 or
      Form S-8 or their then  equivalents  relating to equity  securities  to be
      issued solely in connection with any acquisition of any entity or business
      or equity  securities  issuable in  connection  with stock option or other
      employee  benefit plans,  the Company shall send to each Investor,  who is
      entitled to registration  rights under this Section 2(b) written notice of
      such  determination  and, if within twenty (20) days after receipt of such
      notice,  such  Investor  shall so request in writing,  the  Company  shall
      include in such Registration  Statement all or any part of the Registrable
      Securities  such Investor  requests to be  registered,  except that if, in
      connection  with any  underwritten  public offering for the account of the
      Company the managing  underwriter(s)  thereof shall impose a limitation on
      the  number  of  shares  of Common  Stock  which  may be  included  in the
      Registration  Statement because, in such  underwriter(s)'  judgment,  such
      limitation is necessary to effect an orderly public distribution, then the
      Company shall be obligated to include in such Registration  Statement only
      such limited portion,  if any, of the Registrable  Securities with respect
      to which such Investor has requested inclusion hereunder. Any exclusion of
      Registrable  Securities shall be made pro rata among the Investors seeking
      to  include  Registrable  Securities,  in  proportion  to  the  number  of
      Registrable Securities sought to be included by such Investors;  provided,
      however,  that the Company  shall not exclude any  Registrable  Securities
      unless the Company  has first  excluded  all  outstanding  securities  the
      holders of which are not entitled by right to inclusion of  securities  in
      such Registration Statement; and provided,  further,  however, that, after
      giving  effect to the  immediately  preceding  proviso,  any  exclusion of
      Registrable  Securities  shall  be made  pro rata  with  holders  of other
      securities having the right to include such securities in the Registration
      Statement to the extent such pro rata  allotment  is  permitted  under the
      Company's currently existing agreements with such holders of the Company's
      securities.  No right to registration of Registrable Securities under this
      Section 2(b) shall be construed to limit any  registration  required under
      Section 2(c) hereof.  The  obligations  of the Company  under this Section
      2(b) may be waived by  Investors  holding a majority  in  interest  of the
      Registrable Securities and shall expire (i) after the Company has afforded
      the  opportunity for the Investors to exercise  registration  rights under
      this  Section  2(b) for two  registrations;  provided,  however,  that any
      Investor who shall have had any Registrable  Securities  excluded from any
      Registration  Statement  in  accordance  with this  Section  2(b) shall be
      entitled to include in an additional  Registration  Statement filed by the
      Company  the  Registrable  Securities  so excluded or (ii) when all of the
      Registrable  Securities  held by any Investor may be sold by such Investor
      under  Rule  144  under  the   Securities  Act  ("Rule  144")  within  any
      three-month period.

            (C) DEMAND REGISTRATION.  If, at any time after the date which is 30
      days after the closing  under the  Subscription  Agreement,  any  Investor
      holding a majority of the Registrable  Securities shall notify the Company
      in writing that it intends to offer or cause to be offered for public sale
      Registrable Securities held by such Investor, the Company shall cause such
      of the  Registrable  Securities  as may be requested by any Investor to be
      registered,  on one occasion only, under the Securities Act and applicable
      state laws as expeditiously  as possible.  Once the right for registration
     

<PAGE>

      of any Registrable  Securities  under this Section 2(c) has been exercised
      by any  Investor,  the  Company  shall  prepare  and  file a  Registration
      Statement covering such Registrable  Securities with the SEC within twenty
      (20) days of the exercise of such registration right.

            (D) If any offering pursuant to a Registration Statement pursuant to
      Section 2(c) hereof  involves (at the Company's  election) an underwritten
      offering, the Investors who hold a majority in interest of the Registrable
      Securities  subject to such underwritten  offering shall have the right to
      select one legal counsel and an  investment  banker or bankers and manager
      or managers to administer the offering, which investment banker or bankers
      or manager or managers  shall be reasonably  satisfactory  to the Company.
      The Investors who hold the  Registrable  Securities to be included in such
      underwriting  shall pay all  underwriting  discounts and  commissions  and
      other fees and expenses of such  investment  banker or bankers and manager
      or managers so selected in  accordance  with this Section 2(d) (other than
      fees and expenses relating to registration of Registrable Securities under
      federal or state securities laws which are payable by the Company pursuant
      to Section 5 hereof) with respect to their Registrable  Securities and the
      fees and expenses of such legal counsel selected by the Investors.

            As used in this Section  2(a),  the  following  terms shall have the
      following meanings:

            "Aggregate  Market  Value" of any  shares of Common  Stock as of any
      Computation Date means the product obtained by multiplying (a) such number
      of shares of Common Stock times (b) the Average Market Price of the Common
      Stock for the Measurement Period for such Computation Date.

            "Average  Market  Price" of any  security  for any  period  shall be
      computed  as the  average  closing  price  of the  shares  over  the  five
      trading-day period ending on the relevant Computation Date, as reported by
      Bloomberg, L.P.

            "Measurement  Period"  means the period of ten  consecutive  trading
      days for the Common Stock ending on (or on the last trading day preceding)
      each Computation Date.

            3.    OBLIGATIONS OF THE COMPANY.   In connection with the
      registration of the Registrable Securities, the Company shall:

            (a) prepare promptly and file with the SEC promptly (but in no event
      later than 20 days) after a request in accordance with Section 2(b) hereof
      a  Registration  Statement or Statements  with respect to all  Registrable
      Securities to be included therein,  and thereafter use its best efforts to
      cause the Registration Statement to become effective as soon as reasonably
      possible  after  such  filing.  If such  Registration  Statement  is filed
      pursuant to Rule 415, the Company  shall keep the  Registration  Statement
      effective  pursuant  to Rule 415 at all times  until such date as is three
      years  after  the  date  such  Registration  Statement  is  first  ordered
      effective by the SEC. In any case, the Registration  Statement  (including
      any amendments or supplements thereto and prospectuses  contained therein)
      filed by the Company shall not contain any untrue  statement of a material
      fact or omit to state a material  fact required to be stated  therein,  or
      necessary to make the statements therein, in light of the circumstances in
      which they were made, not misleading;  provided, however, that, subject to

<PAGE>

      the conditions  set forth in Section 4(a) below,  each Investor may notify
      the  Company in writing  that it wishes to exclude all or a portion of its
      Registrable Securities from such Registration Statement; provided further,
      however,  that if at any time the Investors  shall be entitled to sell all
      Registrable Securities held by them pursuant to Rule 144 promulgated under
      the Securities Act or any other similar rule or regulation of the SEC that
      may at any time permit the Investors to sell  securities of the Company to
      the public without registration and without imposing  restrictions arising
      under the federal  securities laws on the purchases thereof in a period of
      three consecutive  months, then the Company shall, so long as it meets the
      current public information  requirements of Rule 144, thereafter no longer
      be  required  to  maintain  the  registration  of  Registrable  Securities
      pursuant to this Agreement;

            (b)  prepare  and  file  with  the SEC  such  amendments  (including
      post-effective  amendments) and supplements to the Registration  Statement
      and the prospectus used in connection with the  Registration  Statement as
      may be necessary to keep the Registration Statement effective at all times
      until  such  date as is  three  years  after  the date  such  Registration
      Statement is first ordered  effective by the SEC, and, during such period,
      comply  with the  provisions  of the  Securities  Act with  respect to the
      disposition of all  Registrable  Securities of the Company  covered by the
      Registration  Statement  until  such  time  as  all  of  such  Registrable
      Securities have been disposed of in accordance  with the intended  methods
      of  disposition  by the  seller  or  sellers  thereof  as set forth in the
      Registration Statement;

            (c)  furnish  to each  Investor  whose  Registrable  Securities  are
      included  in the  Registration  Statement,  such  number  of  copies  of a
      prospectus,  including a preliminary  prospectus,  and all  amendments and
      supplements  thereto  and  such  other  documents  as  such  Investor  may
      reasonably   request  in  order  to  facilitate  the  disposition  of  the
      Registrable Securities owned by such Investor;

            (d)  use  reasonable   efforts  to  (i)  register  and  qualify  the
      Registrable  Securities  covered by the Registration  Statement under such
      other  securities or blue sky laws of such  jurisdictions as the Investors
      who hold a  majority  in  interest  of the  Registrable  Securities  being
      offered reasonably  request,  (ii) prepare and file in those jurisdictions
      such amendments  (including  post-effective  amendments) and  supplements,
      (iii)  take such  other  actions  as may be  necessary  to  maintain  such
      registrations and qualifications in effect at all times until such date as
      is the earlier of three years after the date such  Registration  Statement
      is first ordered  effective by the SEC or is three years after the Initial
      Investor  acquired the Shares and (iv) take all other  actions  reasonably
      necessary or advisable to qualify the  Registrable  Securities for sale in
      such  jurisdictions;  provided,  however,  that the  Company  shall not be
      required in connection  therewith or as a condition thereto to (I) qualify
      to do  business  in any  jurisdiction  where it  would  not  otherwise  be
      required to qualify but for this  Section  3(d),  (II)  subject  itself to
      general taxation in any such jurisdiction, (III) file a general consent to
      service of process in any such jurisdiction, (IV) provide any undertakings
      that cause more than nominal  expense or burden to the Company or (V) make
      any  change in its  charter  or  by-laws,  which in each case the Board of
      Directors of the Company  determines to be contrary to the best  interests
      of the Company and its stockholders;

<PAGE>

            (e) in the event  Investors  who hold a majority  in interest of the
      Registrable  Securities being offered in the offering select  underwriters
      for the  offering,  enter  into  and  perform  its  obligations  under  an
      underwriting  agreement,  in usual and customary form, including,  without
      limitation,  customary indemnification and contribution obligations,  with
      the managing underwriter of such offering;

            (f) as promptly as  practicable  after becoming aware of such event,
      notify each Investor who holds Registrable  Securities being sold pursuant
      to such  registration  of the  happening of any event of which the Company
      has  knowledge,  as a  result  of which  the  prospectus  included  in the
      Registration Statement, as then in effect, includes an untrue statement of
      a material  fact or omits to state a material  fact  required to be stated
      therein  or  necessary  to make the  statements  therein,  in light of the
      circumstances under which they were made, not misleading, and use its best
      efforts  promptly to prepare a supplement or amendment to the Registration
      Statement  to correct such untrue  statement  or  omission,  and deliver a
      number of copies of such  supplement or amendment to each Investor as such
      Investor may reasonably request;

            (g) as promptly as  practicable  after becoming aware of such event,

      to such  registration (or, in the event of an underwritten  offering,  the
      managing  underwriters)  of the  issuance  by the SEC of any stop order or
      other suspension of  effectiveness  of the  Registration  Statement at the
      earliest possible time;

            (h)  permit  a  single  firm  of  counsel   designated   as  selling
      stockholders'  counsel by the Investors who hold a majority in interest of
      the  Registrable  Securities  being sold pursuant to such  registration to
      review the  Registration  Statement  and all  amendments  and  supplements
      thereto a  reasonable  period of time prior to their  filing with the SEC,
      and shall not file any document in a form to which such counsel reasonably
      objects;

            (i) make  generally  available  to its  security  holders as soon as
      practical,  but not later  than  ninety  (90) days  after the close of the

      provisions of Rule 158 under the Securities  Act) covering the fiscal year
      period  beginning  not later  than the first day of the  Company's  fiscal
      quarter next following the date of the Registration Statement;

            (j) at the request of the  Investors who hold a majority in interest

      furnish  on the date  that  Registrable  Securities  are  delivered  to an
      underwriter for sale in connection with the  Registration  Statement (i) a
      letter, dated such date, from the Company's  independent  certified public
      accountants in form and substance as is  customarily  given by independent
      certified  public  accountants to underwriters  in an underwritten  public
      offering,  addressed to the underwriters;  and (ii) an opinion, dated such
      date,  from  counsel   representing  the  Company  for  purposes  of  such

      Investors;

<PAGE>

            (k) make available for inspection by any Investor whose  Registrable
      Securities are being sold pursuant to such  registration,  any underwriter
      participating in any disposition  pursuant to the Registration  Statement,
      and any attorney,  accountant or other agent retained by any such Investor
      or underwriter (collectively,  the "Inspectors"),  all pertinent financial
      and other  records,  pertinent  corporate  documents and properties of the
      Company (collectively, the "Records"), as shall be reasonably necessary to
      enable each  Inspector to exercise its due diligence  responsibility,  and
      cause the  Company's  officers,  directors  and  employees  to supply  all
      information  which any  Inspector may  reasonably  request for purposes of
      such due diligence;  provided,  however, that each Inspector shall hold in
      confidence  and shall not make any  disclosure  (except to an Investor) of
      any Record or other information which the Company determines in good faith
      to be  confidential,  and of which  determination  the  Inspectors  are so
      notified,  unless (i) the disclosure of such Records is necessary to avoid
      or correct a misstatement or omission in any Registration Statement,  (ii)
      the  release of such  Records is ordered  pursuant  to a subpoena or other
      order from a court or government  body of competent  jurisdiction or (iii)
      the  information in such Records has been made generally  available to the
      public  other  than by  disclosure  in  violation  of  this  or any  other
      agreement.  The Company shall not be required to disclose any confidential
      information  in such  Records  to any  Inspector  until  and  unless  such
      Inspector shall have entered into confidentiality  agreements (in form and
      substance  satisfactory  to the  Company)  with the Company  with  respect
      thereto,  substantially  in the form of this Section  3(k).  Each Investor
      agrees that it shall,  upon  learning  that  disclosure of such Records is
      sought in or by a court or governmental body of competent  jurisdiction or
      through  other  means,  give  prompt  notice to the  Company and allow the
      Company,  at its  expense,  to  undertake  appropriate  action to  prevent
      disclosure  of, or to obtain a protective  order for,  the Records  deemed
      confidential.  The Company shall hold in confidence and shall not make any
      disclosure of information  concerning an Investor  provided to the Company
      pursuant to Section 4(e) hereof unless (i) disclosure of such  information
      is  necessary to comply with federal or state  securities  laws,  (ii) the
      disclosure  of such  information  is  necessary  to  avoid  or  correct  a
      misstatement or omission in any Registration Statement,  (iii) the release
      of such  information is ordered pursuant to a subpoena or other order from
      a court  or  governmental  body of  competent  jurisdiction  or (iv)  such
      information has been made generally  available to the public other than by
      disclosure in violation of this or any other agreement. The Company agrees
      that  it  shall,   upon  learning  that  disclosure  of  such  information
      concerning an Investor is sought in or by a court or governmental  body of
      competent  jurisdiction or through other means, give prompt notice to such
      Investor,  at its  expense,  to  undertake  appropriate  action to prevent
      disclosure of, or to obtain a protective order for, such information;

            (l) use its best  efforts  either to (i)  cause all the  Registrable
      Securities  covered  by  the  Registration  Statement  to be  listed  on a
      national  securities  exchange,  which shall include the Nasdaq  Small-Cap
      Market,  and on each  additional  national  securities  exchange  on which
      similar  securities  issued by the Company are then listed, if any, if the
      listing of such  Registrable  Securities is then permitted under the rules

<PAGE>

      of  such  exchange,  or (ii)  secure  designation  of all the  Registrable
      Securities covered by the Registration Statement as a National Association
      of Securities  Dealers Automated  Quotations  System ("Nasdaq")  "national
      market  system  security"  within the  meaning of Rule  11Aa2-1 of the SEC
      under the  Securities  Exchange  Act of 1934,  as amended  (the  "Exchange
      Act"),  and the  quotation  of the  Registrable  Securities  on the Nasdaq
      National  Market  System or, if,  despite the  Company's  best  efforts to
      satisfy the preceding  clause (i) or (ii), the Company is  unsuccessful in
      satisfying  the  preceding  clause  (i) or (ii),  to secure  listing  on a
      national  securities  exchange or Nasdaq  authorization  and quotation for
      such  Registrable  Securities and,  without limiting the generality of the
      foregoing,  to arrange for at least two market makers to register with the
      National  Association of Securities  Dealers,  Inc.  ("NASD") as such with
      respect to such Registrable Securities;

            (m) provide a transfer  agent and  registrar,  which may be a single
      entity,  for the Registrable  Securities not later than the effective date
      of the Registration Statement;

            (n) cooperate  with the Investors  who hold  Registrable  Securities
      being  sold and the  managing  underwriter  or  underwriters,  if any,  to
      facilitate   the  timely   preparation   and   delivery  of   certificates
      representing   Registrable   Securities   to  be  sold   pursuant  to  the
      denominations  or amounts as the case may be, and registered in such names
      as the managing underwriter or underwriters,  if any, or the Investors may
      reasonably request; and

            (o) take all other  reasonable  actions  necessary  to expedite  and
      facilitate  disposition  by the  Investor  of the  Registrable  Securities
      pursuant to the Registration Statement;

            4.    OBLIGATIONS OF THE INVESTORS.  In connection with the
      registration of the Registrable Securities, the Investors shall have
      the following obligations:

            (a) It shall be a  condition  precedent  to the  obligations  of the
      Company to take any action pursuant to this Agreement with respect to each
      Investor that such Investor shall furnish to the Company such  information
      regarding itself,  the Registrable  Securities held by it and the intended
      method of disposition of the Registrable Securities held by it as shall be
      reasonably   required  to  effect  the  registration  of  the  Registrable
      Securities  and shall  execute  such  documents  in  connection  with such
      registration as the Company may reasonably  request. At least fifteen (15)
      days  prior  to the  first  anticipated  filing  date of the  Registration
      Statement,  the Company shall notify each Investor of the  information the
      Company requires from each such Investor (the "Requested  Information") if
      such Investor elects to have any of such Investor's Registrable Securities
      included in the Registration  Statement.  If within five (5) business days
      prior to the  filing  date the  Company  has not  received  the  Requested
      Information  from an  Investor  (a  "Non-Responsive  Investor"),  then the
      Company may file the Registration  Statement without including Registrable
      Securities of such Non-Responsive Investor;


<PAGE>

            (b) Each Investor by such  Investor's  acceptance of the Registrable
      Securities agrees to cooperate with the Company as reasonably requested by
      the  Company  in  connection  with  the  preparation  and  filing  of  the
      Registration  Statement  hereunder,  unless such Investor has notified the
      Company in  writing of such  Investor's  election  to exclude  all of such
      Investor's Registrable Securities from the Registration Statement;

            (c) In the event  Investors  holding a majority  in  interest of the
      Registrable  Securities being registered  determine to engage the services
      of an  underwriter,  each  Investor  agrees to enter into and perform such
      Investor's  obligations  under an  underwriting  agreement,  in usual  and
      customary form, including,  without limitation,  customary indemnification
      and  contribution  obligations,  with  the  managing  underwriter  of such
      offering and take such other actions as are  reasonably  required in order
      to expedite or facilitate the disposition of the  Registrable  Securities,
      unless  such  Investor  has  notified  the  Company  in  writing  of  such
      Investor's  election  to  exclude  all  of  such  Investor's   Registrable
      Securities from the Registration Statement;

            (d) Each Investor  agrees that,  upon receipt of any notice from the
      Company of the  happening  of any event of the kind  described  in Section
      3(f) or 3(g), such Investor will  immediately  discontinue  disposition of
      Registrable  Securities  pursuant to the Registration  Statement  covering
      such Registrable Securities until such Investor's receipt of the copies of
      the  supplemented  or amended  prospectus  contemplated by Section 3(f) or
      3(g) and, if so directed by the Company,  such  Investor  shall deliver to
      the Company (at the expense of the Company) or destroy (and deliver to the
      Company a  certificate  of  destruction)  all  copies  in such  Investor's
      possession, of the prospectus covering such Registrable Securities current
      at the time of receipt of such notice; and

            (e) No Investor may  participate  in any  underwritten  registration
      hereunder  unless  such  Investor  (i)  agrees  to  sell  such  Investor's
      Registrable   Securities  on  the  basis  provided  in  any   underwriting
      arrangements  approved by the Investors entitled hereunder to approve such
      arrangements,  (ii) completes and executes all  questionnaires,  powers of
      attorney,   indemnities,   underwriting  agreements  and  other  documents
      reasonably required under the terms of such underwriting  arrangements and
      (iii) agrees to pay its pro rata share of all  underwriting  discounts and
      commissions  and other fees and  expenses  of  investment  bankers and any
      manager  or  managers  of such  underwriting  and  legal  expenses  of the
      underwriter applicable with respect to its Registrable Securities, in each
      case to the extent not  payable by the  Company  pursuant  to the terms of
      this Agreement.

            5. EXPENSES OF REGISTRATION.  All expenses (other than  underwriting
      discounts  and  commissions  and other  fees and  expenses  of  investment
      bankers and other than brokerage  commissions) incurred in connection with
      registrations, filings or qualifications pursuant to Section 3, including,
      without  limitation,  all registration,  listing and qualifications  fees,
      printers and accounting fees and the fees and disbursements of counsel for
      the Company,  shall be borne by the Company;  provided,  however, that the
      Investors shall bear the fees and out-of-pocket  expenses of the one legal
      counsel selected by the Investors pursuant to Section 3(h) hereof.

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

            (a) To the extent  permitted by law, the Company will  indemnify and
      hold  harmless each Investor who holds such  Registrable  Securities,  the
      directors,  if any,  of  such  Investor,  the  officers,  if any,  of such
      Investor,  each person,  if any,  who  controls  any  Investor  within the
      meaning of the  Securities  Act or the Exchange Act, any  underwriter  (as
      defined in the Securities Act) for the Investors,  the directors,  if any,
      of such  underwriter and the officers,  if any, of such  underwriter,  and
      each person, if any, who controls any such underwriter  within the meaning
      of the Securities Act or the Exchange Act (each, an "Indemnified Person"),
      against any losses,  claims,  damages,  expenses or liabilities  (joint or
      several) (collectively "Claims") to which any of them become subject under
      the Securities Act, the Exchange Act or otherwise,  insofar as such Claims
      (or actions or proceedings,  whether  commenced or threatened,  in respect
      thereof)  arise out of or are based upon any of the following  statements,
      omissions  or   violations   in  the   Registration   Statement,   or  any
      post-effective  amendment thereof, or any prospectus included therein: (i)
      any  untrue  statement  or alleged  untrue  statement  of a material  fact
      contained in the Registration  Statement or any  post-effective  amendment
      thereof or the  omission or alleged  omission to state  therein a material
      fact  required to be stated  therein or necessary  to make the  statements
      therein  not  misleading,  (ii) any untrue  statement  or  alleged  untrue
      statement of a material fact  contained in any  preliminary  prospectus if
      used  prior  to the  effective  date of such  Registration  Statement,  or
      contained  in the final  prospectus  (as amended or  supplemented,  if the
      Company files any amendment thereof or supplement thereto with the SEC) or
      the  omission or alleged  omission  to state  therein  any  material  fact
      necessary  to  make  the  statements   made  therein,   in  light  of  the
      circumstances under which the statements therein were made, not misleading
      or  (iii)  any  violation  or  alleged  violation  by the  Company  of the
      Securities  Act, the Exchange Act or any state  securities law or any rule
      or  regulation  (the  matters in the  foregoing  clauses (i) through  (iv)
      being, collectively,  "Violations"). Subject to the restrictions set forth
      in Section 6 (d) with respect to the number of legal counsel,  the Company
      shall  reimburse the Investors and each such  underwriter  or  controlling
      person,  promptly as such  expenses  are incurred and are due and payable,
      for any  legal  fees or  other  reasonable  expenses  incurred  by them in
      connection with investigating or defending any such Claim. Notwithstanding
      anything to the contrary contained herein, the  indemnification  agreement
      contained in this Section 6(a) (I) shall not apply to a Claim  arising out
      of or  based  upon a  Violation  which  occurs  in  reliance  upon  and in
      conformity  with  information  furnished  in writing to the Company by any
      Indemnified  Person or underwriter for such  Indemnified  Person expressly
      for use in connection with the preparation of the  Registration  Statement
      or any such amendment  thereof or supplement  thereto,  if such prospectus
      was timely made available by the Company  pursuant to Section 3(c) hereof;
      (II) with  respect to any  preliminary  prospectus  shall not inure to the
      benefit of any such person from whom the person  asserting  any such Claim
      purchased the  Registrable  Securities that are the subject thereof (or to
      the benefit of any person controlling such person) if the untrue statement
      or omission of material fact contained in the  preliminary  prospectus was

<PAGE>


      
      corrected  in the  prospectus,  as then amended or  supplemented,  if such
      prospectus  was timely made  available by the Company  pursuant to Section
      3(c) hereof;  and (III) shall not apply to amounts paid in  settlement  of
      any Claim if such settlement is effected without the prior written consent
      of the Company,  which consent shall not be  unreasonably  withheld.  Such
      indemnity  shall  remain  in  full  force  and  effect  regardless  of any
      investigation  made by or on behalf of the  Indemnified  Persons and shall
      survive  the  transfer  of the  Registrable  Securities  by the  Investors
      pursuant to Section 9.

            (b) In  connection  with  any  Registration  Statement  in  which an
      Investor is participating, each such Investor agrees to indemnify and hold
      harmless,  to the same  extent and in the same manner set forth in Section
      6(a), the Company,  each of its directors,  each of its officers who signs
      the Registration Statement,  each person, if any, who controls the Company
      within  the  meaning  of  the  Securities  Act or the  Exchange  Act,  any
      underwriter and any other stockholder  selling securities  pursuant to the
      Registration  Statement or any of its  directors or officers or any person
      who controls such  stockholder  or  underwriter  within the meaning of the
      Securities  Act or the Exchange  Act  (collectively  and together  with an
      Indemnified  Person, an "Indemnified  Party"),  against any Claim to which
      any of them may become subject, under the Securities Act, the Exchange Act
      or  otherwise,  insofar as such  Claim  arises out of or is based upon any
      Violation,  in each case to the extent (and only to the extent)  that such
      Violation  occurs (I) in  reliance  upon and in  conformity  with  written
      information furnished to the Company by such Investor expressly for use in
      connection  with  such  Registration  Statement  or  (II)  the  Investor's
      violation  of Rules  10-b-6 or 10-b-7  under the  Exchange  Act;  and such
      Investor will promptly  reimburse any legal or other  expenses  reasonably
      incurred by them in connection  with  investigating  or defending any such
      Claim;  provided,  however, that the indemnity agreement contained in this
      Section 6(b) shall not apply to amounts paid in settlement of any Claim if
      such  settlement  is effected  without the prior  written  consent of such
      Investor,  which consent  shall not be  unreasonably  withheld;  provided,
      further,  however,  that the  Investor  shall be liable under this Section
      6(b) for only that  amount of a Claim as does not exceed the net  proceeds
      to  such  Investor  as a  result  of the  sale of  Registrable  Securities
      pursuant to such  Registration  Statement.  Such indemnity shall remain in
      full force and effect regardless of any investigation made by or on behalf
      of  such  Indemnified   Party  and  shall  survive  the  transfer  of  the
      Registrable   Securities   by  the   Investors   pursuant  to  Section  9.
      Notwithstanding   anything  to  the   contrary   contained   herein,   the
      indemnification  agreement  contained in this Section 6(b) with respect to
      any  preliminary  prospectus  shall  not  inure  to  the  benefit  of  any
      Indemnified  Party if the untrue  statement  or omission of material  fact
      contained in the preliminary prospectus was corrected on a timely basis in
      the prospectus, as then amended or supplemented.

            (c) The  Company  shall be  entitled  to  receive  indemnities  from
      underwriters,  selling  brokers,  dealer  managers and similar  securities
      industry  professionals  participating  in any  distribution,  to the same
      extent as provided  above,  with  respect to  information  such persons so
      furnished  in writing  by such  persons  expressly  for  inclusion  in the
      Registration Statement.

<PAGE>

            (d) Promptly after receipt by an  Indemnified  Person or Indemnified
      Party  under this  Section 6 of notice of the  commencement  of any action
      (including  any  governmental   action),   such   Indemnified   Person  or
      Indemnified  Party shall, if a Claim in respect thereof is to made against
      any  indemnifying  party under this Section 6, deliver to the indemnifying
      party a written notice of the commencement  thereof and this  indemnifying
      party  shall  have the right to  participate  in,  and,  to the extent the
      indemnifying  party so desires,  jointly with any other indemnifying party
      similarly  noticed,  to assume control of the defense thereof with counsel
      mutually satisfactory to the indemnifying parties; provided, however, that
      an Indemnified  Person or Indemnified Party shall have the right to retain
      its own counsel, with the fees and expenses to be paid by the indemnifying
      party,  if,  in  the  reasonable   opinion  of  counsel  retained  by  the
      indemnifying  party, the representation by such counsel of the Indemnified
      Person  or  Indemnified   Party  and  the  indemnifying   party  would  be
      inappropriate due to actual or potential  differing interests between such
      Indemnified  Person or  Indemnified  Party and other party  represented by
      such  counsel  in such  proceeding.  The  Company  shall  pay for only one
      separate  legal  counsel for the  Investors;  such legal  counsel shall be
      selected  by  the  Investors   holding  a  majority  in  interest  of  the
      Registrable  Securities.  The  failure  to deliver  written  notice to the
      indemnifying  party within a reasonable  time of the  commencement  of any
      such action shall not relieve such indemnifying  party of any liability to
      the Indemnified  Person or Indemnified  Party under this Section 6, except
      to the extent that the indemnifying  party is prejudiced in its ability to
      defend such action. The  indemnification  required by this Section 6 shall
      be made by periodic  payments of the amount  thereof  during the course of
      the investigation or defense,  as such expense,  loss, damage or liability
      is incurred and is due and payable.

            7.  CONTRIBUTION.  To the extent any  indemnification  provided  for
      herein is prohibited or limited by law, the  indemnifying  party agrees to
      make the  maximum  contribution  with  respect to any amounts for which it
      would otherwise be liable under Section 6 to the fullest extent  permitted
      by law;  provided,  however,  that (a) no contribution shall be made under
      circumstances   where  the  maker   would   not  have  been   liable   for
      indemnification  under the fault  standards set forth in Section 6, (b) no
      seller of Registrable  Securities  guilty of fraudulent  misrepresentation
      (within  the  meaning of  Section  11(f) of the  Securities  Act) shall be
      entitled to contribution from any seller of Registrable Securities who was
      not guilty of such fraudulent  misrepresentation  and (c)  contribution by
      any seller of Registrable Securities shall be limited in amount to the net
      amount  of  proceeds  received  by  such  seller  from  the  sale  of such
      Registrable Securities.

            8. REPORTS UNDER  EXCHANGE  ACT. With a view to making  available to
      the  Investors  the  benefits  of Rule 144 or any  other  similar  rule or
      regulation  of the SEC that may at any time permit the  Investors  to sell
      securities of the Company to the public without  registration,  until such
      time as the Investors have sold all the Registrable Securities pursuant to
      a Registration Statement or Rule 144, the Company agrees to:

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

<PAGE>


            (b) file  with the SEC in a timely  manner  all  reports  and  other
      documents  required  of the  Company  under  the  Securities  Act  and the
      Exchange Act; and

            (c)  furnish  to  each  Investor  so  long  as  such  Investor  owns
      Registrable Securities,  promptly upon request, (i) a written statement by
      the Company that it has complied with the reporting  requirements  of Rule
      144,  the  Securities  Act and the Exchange  Act,  (ii) a copy of the most
      recent  annual or quarterly  report of the Company and such other  reports
      and documents so filed by the Company and (iii) such other  information as
      may  be  reasonably  requested  to  permit  the  Investors  to  sell  such
      securities pursuant to Rule 144 without registration.

            9.  ASSIGNMENT OF THE  REGISTRATION  RIGHTS.  The rights to have the
      Company register  Registrable  Securities pursuant to this Agreement shall
      be automatically  assigned by the Investors to transferees or assignees of
      all or any portion of such  securities only if: (a) the Company is, within
      a  reasonable  time after such  transfer  or  assignment,  furnished  with
      written notice of (i) the name and address of such  transferee or assignee
      and (ii) the securities with respect to which such registration rights are
      being transferred or assigned,  (b) immediately following such transfer or
      assignment the further disposition of such securities by the transferee or
      assignee is  restricted  under the  Securities  Act and  applicable  state
      securities  laws,  and (c) at or before the time the Company  received the
      written notice  contemplated by clause (a) of this sentence the transferee
      or assignee  agrees in writing  with the Company to be bound by all of the
      provisions contained herein.

            10.  AMENDMENT  OF  REGISTRATION   RIGHTS.  Any  provision  of  this
      Agreement may be amended and the observance  thereof may be waived (either
      generally  or  in  a  particular  instance  and  either  retroactively  or
      prospectively), only with the written consent of the Company and Investors
      who  hold a  majority  in  interest  of the  Registrable  Securities.  Any
      amendment or waiver  effected in accordance  with this Section 10 shall be
      binding upon each Investor and the Company.

            11. THIRD PARTY BENEFICIARY.  The parties acknowledge and agree that
      Shoreline  Pacific,  the  Institutional  Division of Financial  West Group
      ("Shoreline  Pacific"),  shall be deemed a third party  beneficiary of the
      Company's  agreements  and  representations  set forth in this  Agreement,
      entitled  to enforce the terms  thereof,  and to  indemnification  for any
      damages  resulting  to  Shoreline  Pacific  from any actual or  threatened
      breach  thereof  by the  Company,  both in  Shoreline  Pacific's  personal
      capacity  and,  should  Shoreline  Pacific  so  elect,  on  behalf  of the
      Investor.

            12.  MISCELLANEOUS.

            (a) A person or  entity  is  deemed  to be a holder  of  Registrable
      Securities  whenever such person or entity owns of record such Registrable
      Securities. If the Company receives conflicting  instructions,  notices or
      elections  from two or more  persons or entities  with respect to the same
      Registrable   Securities,   the  Company  shall  act  upon  the  basis  of
      instructions,  notice or election  received from the  registered  owner of
      such Registrable Securities.

<PAGE>

            (b) Notices  required or permitted to be given hereunder shall be in
      writing  and shall be  deemed to be  sufficiently  given  when  personally
      delivered  or when sent by  registered  mail,  return  receipt  requested,
      addressed  (i) if to the  Company,  at Viragen,  Inc2343 West 76th Street,
      Hialeah,  FL 33942,  Attention:  Gerald Smith,  President,  (ii) if to the
      Initial  Investor,  at  the  address  set  forth  under  its  name  in the
      Subscription Agreement and (iii) if to any other Investor, at such address
      as such Investor shall have provided in writing to the Company, or at such
      other  address as each such party  furnishes by notice given in accordance
      with  this  Section  12(b),  and  shall  be  effective,   when  personally
      delivered, upon receipt, and when so sent by certified mail, four business
      days after deposit with the United States Postal Service.

            (c) Failure of any party to exercise  any right or remedy under this
      Agreement or otherwise,  or delay by a party in  exercising  such right or
      remedy, shall not operate as a waiver thereof.

            (d) This Agreement  shall be enforced,  governed by and construed in
      accordance  with the  laws of the  State  of New  York  applicable  to the
      agreements made and to be performed  entirely  within such state,  without
      giving  effect to rules  governing the conflict of laws. In the event that
      any  provision  of this  Agreement is invalid or  unenforceable  under any
      applicable  statute or rule of law,  then such  provision  shall be deemed
      inoperative  to the extent  that it may  conflict  therewith  and shall be
      deemed modified to conform with such statute or rule of law. Any provision
      hereof which may prove  invalid or  unenforceable  under any law shall not
      affect the validity or enforceability of any other provision hereof.

            (e) This  Agreement  constitutes  the  entire  agreement  among  the
      parties  hereto with respect to the subject  matter  hereof.  There are no
      restrictions,  promises, warranties or undertakings,  other than those set
      forth  or  referred  to  herein.  This  Agreement   supersedes  all  prior
      agreements and understandings among the parties hereto with respect to the

                             ______________ Warrants

                         to Purchase ____________ Shares

                    of Common Stock, $.01 Par Value Per Share


      VIRAGEN,  INC., a Delaware  corporation (the "Company"),  hereby certifies

assigns  (collectively,  the  "Holder"),  for value  received,  is  entitled  to
purchase from the Company at any time  commencing on December 6, 1996 up through
December 6, 1999,  ______________ shares (the "Warrant Shares") of the Company's
common stock, par value $.01 per share (the "Common Stock"),  at $2.00 per share
(the "Exercise Price").

      1. Exercise of Warrants.  Upon  presentation  and surrender of this Common
Stock   Purchase   Warrant   Certificate   ("Warrant   Certificate"   or   "this
Certificate"),  with the attached Purchase Form duly executed,  at the principal
office of the Company at 2343 West 76th Street, Hialeah, Florida 33016, together
with a bank check,  certified  check or other form of payment  acceptable to the
Company in the amount of the Exercise Price  multiplied by the number of Warrant
Shares being purchased, the Company, or the Company's Transfer Agent as the case
may be, shall deliver to the holder hereof,  certificates  of Common Stock which
in the aggregate  represent the number of Warrant Shares being  purchased.  This
Warrant  Certificate  may be  exercised  as to 25% of the  underlying  shares of
Common Stock on or after the tenth day  following  the date that a  Registration
Statement  covering  the  resale of the Common  Stock  underlying  this  Warrant
Certificate  shall have been declared  effective by the  Securities and Exchange
Commission (the "First Conversion Date"), with an additional 25% of this Warrant
Certificate  becoming  exercisable  30,  60  and 90  days  following  the  First
Conversion Date, respectively. To the extent that this Warrant Certificate shall
not have been  exercised to the full extent  permitted by the terms hereof as of
the respective  dates provided above,  the amount of Warrant Shares with respect
to which this Warrant Certificate shall be exercisable shall be cumulative.




<PAGE>



All or  less  than  all of the  Warrants  represented  by this  Certificate,  as
provided above,  may be exercised and, in case of the exercise of less than all,
the Company,  upon  surrender  hereof,  will deliver to the holder a new Warrant
Certificate or  Certificates  of like tenor and dated the date hereof  entitling
said  holder to  purchase  the  number of  Warrant  Shares  represented  by this
Certificate  which have not been  exercised and to receive  Registration  Rights
with respect to such Warrant Shares.

       2.  Exchange  and  Transfer.  This  Certificate  at any time prior to the
exercise  hereof,  upon  presentation  and  surrender  to  the  Company,  may be
exchanged, alone or with other Certificates of like tenor registered in the name
of the same holder, for another Certificate or Certificates of like tenor in the
name of such holder  exercisable  for the aggregate  number of Warrant Shares as
the Certificate or Certificates surrendered.

       3.   Rights and Obligations of Holder of this Certificate.

            (a) The Holder of this Certificate  shall not, by virtue hereof,  by
entitled  to any rights of a  stockholder  in the  Company,  either at law or in
equity; provided, however, that in the event any certificate representing shares
of Common Stock or other securities is issued to the holder hereof upon exercise
of some or all of the Warrants,  such holder shall, for all purposes,  be deemed
to have  become the holder of record of such  Common  Stock on the date on which
this  Certificate,  together with a duly executed Purchase Form, was surrendered
and payment of the aggregate  Exercise Price was made,  irrespective of the date
of delivery of such share certificate.

            (b) In case the Company  shall (i) pay a dividend in Common Stock or
make a distribution in Common Stock, (ii) subdivide its outstanding Common Stock
into a greater number of shares,  or (iii) combine its outstanding  Common Stock
into a smaller number of shares (including a recapitalization in connection with
a consolidation  or merger in which the Company is the continuing  corporation),
then (x) the Exercise Price on the record date of such division on the effective
date of such action shall be adjusted by  multiplying  such Exercise  Price by a
fraction,  the  numerator  of which is the  number of  shares  of  Common  Stock
outstanding  immediately  before such event and the  denominator of which is the
number of shares of Common Stock  outstanding  immediately after such event, and
(y) the number of shares of Common Stock for which this Warrant  Certificate may
be exercised immediately before such event shall be adjusted by multiplying such
number by a fraction,  the numerator of which is the Exercise Price  immediately
before such event and the denominator of which is the Exercise Price immediately
after such event as provided in subitem (x) hereinabove.










                                      2


<PAGE>



            (c) In case of any  consolidation  or merger of the Company  with or
into another  corporation  (other than any  consolidation or merger in which the
Company  is  the  continuing  corporation  and  which  does  not  result  in any
reclassification  of the outstanding shares of Common Stock or the conversion of
such  outstanding  shares of Common  Stock into  shares or other  stock or other
securities or property),  or the sale or transfer of the property of the Company
as an entirety or  substantially  as an entirety,  there shall be delivered upon
exercise  of the  Warrant  Certificate  the  number  of shares of stock or other
securities or property to which a holder of the number of shares of Common Stock
would have been entitled upon such action if this Warrant  Certificate  had been
exercised immediately prior to such action.

       4.   Common Stock.

            (a) The Company covenants and agrees that all shares of Common Stock
issuable upon exercise of this Warrant Certificate will, upon delivery,  be duly
and validly authorized and issued, fully-paid and non-assessable.

            (b) The  Company  covenants  and  agrees  that it will at all  times
reserve and keep  available an  authorized  number of shares of its Common Stock
and other applicable securities sufficient to permit the exercise in full of all
outstanding options, warrants and rights, including the Warrants.

            5. Registration Rights. The Holder shall be entitled to registration
rights with respect to the Warrant Shares underlying this Warrant as provided in
that certain Registration Rights Agreement dated even date herewith.

       6. Issuance of  Certificates.  As soon as possible  after full or partial
exercise of this Warrant, but in any event not more than three (3) business days
of receipt of payment by the  Company for such  exercise,  the  Company,  at its
expense,  will cause to be issued in the name of and  delivered to the holder of
this Warrant,  a certificate  or  certificates  for the number of fully paid and
non-assessable  shares of Common Stock to which that holder shall be entitled on
such exercise.  No fractional shares will be issued on exercise of this Warrant.
If on any  exercise of this Warrant a fraction of a share  results,  the Company
will pay the cash value of that fractional share, calculated on the basis of the
Exercise Price.  Prior to registration of the shares of Common Stock  underlying
this Warrant Certificate, as provided in Section 5 hereof, all such certificates
shall bear a  restrictive  legend to the effect that the Shares  represented  by
such  certificate  have not been registered under the Securities Act of 1933, as
amended  (the  "Act"),  and the  Shares  may not be sold or  transferred  in the
absence  of such  registration  or an  exemption  therefrom,  such  legend to be
substantially in the form of the bold face language  appearing on Page 1 of this
Warrant Certificate.

Shares, by his or its acceptance thereof,  agrees that no public distribution of
Warrants or Warrant  Shares will be made in violation of the  provisions  of the

1.    AGREEMENT TO SUBSCRIBE; PURCHASE PRICE

      (i) SELLER and BUYER are executing and delivering  this  Agreement,  which
includes the Registration Rights Agreement annexed hereto, and by this reference
incorporated herein, in reliance upon the exemption from securities registration
afforded by Rule 506 under  Regulation D ("Regulation  D") as promulgated by the
United States Securities and Exchange Commission under the Securities Act; and

      (ii) BUYER  hereby  subscribes  for Fifteen  Thousand  (15,000)  Preferred
Shares (the  "Preferred  Shares"),  at a purchase price of One Thousand  Dollars
($1,000)  U.S.  per  share,  convertible  into  Common  Shares,  or  subject  to

      (iii) BUYER shall pay the purchase  price by delivering  same day funds in
United States Dollars into an escrow (the "Escrow")  established  pursuant to an
Escrow Agreement ("Escrow  Agreement") dated as of the date hereof among SELLER,
BUYER and  Royal  Bank of  Scotland  plc  ("Escrow  Agent"),  all as more  fully

price of $6.00 per  share,  subject to  adjustment  pursuant  to Section  5(iii)
hereof,  and  shall be  released  from  Escrow  to BUYER at the same time as the
Preferred  Shares  and shall be  exercisable  as set forth in the form of Common
Stock Purchase Warrant Certificate attached as Exhibit B to this Agreement.


2.    BUYER'S REPRESENTATIONS AND AGREEMENTS

      BUYER represents, warrants and agrees as follows:

      (i) BUYER understands that the Preferred Shares, Warrants,  Common Shares,
and the Warrant Shares have not been registered under the Securities Act, or any
other applicable securities law, and, accordingly, none of the Preferred Shares,
Warrants,  Common Shares or Warrant  Shares may be offered,  sold,  transferred,
pledged, hypothecated or otherwise disposed of unless registered pursuant to, or
in a transaction  exempt from  registration  under,  the  Securities Act and any
other applicable securities law;

      (ii)  BUYER  is an  "accredited  investor"  within  the  meaning  of  Rule
501(a)(1),  (2), (3), or (7) of Regulation D (an "Accredited  Investor") that is
acquiring  the Shares  either for its own account or as a fiduciary or agent for
one or more  institutional  accounts as to which it exercises  sole  discretion,
each of which is an Accredited Investor. BUYER has such knowledge and experience
in financial and business  matters that it is capable of  evaluating  the merits
and risks of an investment in the Shares. BUYER has had a reasonable opportunity
to ask questions of and receive  answers from SELLER  concerning  SELLER and the
offering of the Shares and Warrants. BUYER is not subscribing for the Shares and
Warrants as a result of or pursuant to any  advertisement,  article,  notice, or
other communication  published in any newspaper,  magazine,  or similar media or
broadcast  over   television  or  radio.   BUYER  is  aware  that  it  (or  such
institutional  account)  may  be  required  to  bear  the  economic  risk  of an
investment in the Shares for an indefinite period, and it (or such institutional
account ) is able to bear such risk for an indefinite period;

      (iii) BUYER is acquiring the  Preferred  Shares,  Warrants and  underlying
Shares  for  its  own  account  or for one or  more  institutional  accounts  as
described in Paragraph  2(ii) hereof,  in each case for investment  purposes and
not with a view to, or for offer or sale in connection  with,  any  distribution
thereof  (subject to any requirement of law that the disposition of its property
or the property of such  institutional  account or accounts remain within its or
their control) except only, in the case of the Shares, a distribution registered
under the  Securities Act or exempt from  registration.  BUYER agrees on its own





<PAGE>

December 31, 1996
Page 3



behalf and on behalf of any such institutional account for which it is acquiring
the  Preferred  Shares and  Warrants to offer,  sell or  otherwise  transfer any
Preferred  Shares and  Warrants  only to  Accredited  Investors  (subject to any
requirement of law that the  disposition of its property or the property of such
institutional  account  or  accounts  remain  within  its or their  control)  in
conformity with the Securities Act and any other  applicable  securities law and
with the  restrictions  on transfer set forth on the  certificate(s)  evidencing
such securities.  BUYER acknowledges that each Preferred Share certificate shall
bear a legend  substantially to the effect of the foregoing  paragraphs 2(i) and
2(ii) and this  paragraph  2(iii).  Such legend  shall be in  substantially  the
following form:

      "THE  SECURITIES  EVIDENCED BY THIS  CERTIFICATE  HAVE NOT BEEN REGISTERED
      UNDER THE  SECURITIES  ACT OF 1933 (THE  "ACT")  AND MAY NOT BE OFFERED OR
      SOLD, TRANSFERRED,  PLEDGED,  HYPOTHECATED OR OTHERWISE DISPOSED OF EXCEPT
      PURSUANT TO AN EFFECTIVE  REGISTRATION STATEMENT UNDER THE ACT OR PURSUANT
      TO AN  AVAILABLE  EXEMPTION  FROM SUCH  REGISTRATION.  THE  HOLDER OF THIS
      CERTIFICATE IS THE  BENEFICIARY OF CERTAIN  OBLIGATIONS OF THE COMPANY SET
      FORTH IN A PRIVATE SECURITIES  SUBSCRIPTION  AGREEMENT BETWEEN THE COMPANY
      AND P.R.I.F.,  L.P.  DATED DECEMBER 31, 1996. A COPY OF THE PORTION OF THE
      AFORESAID  SUBSCRIPTION  AGREEMENT  EVIDENCING  SUCH  OBLIGATIONS  MAY  BE
      OBTAINED FROM THE COMPANY'S EXECUTIVE OFFICES."

      Upon conversion of the Preferred Shares into Common Shares, subject to the
provisions of Section 4(i) hereof, SELLER shall issue a common stock certificate
without such legend to the holder of such shares provided that the  Registration
Statement  covering the Common Shares has been declared effective by the SEC and
remains in effect at the time of conversion.

      (iv)  BUYER   acknowledges   that  each   Warrant   shall  bear  a  legend
substantially to the effect of the foregoing  paragraphs 2(i) and 2(ii) and this
paragraph 2(iv). Such legend shall be in substantially the following form:

      NEITHER  THIS  WARRANT NOR ANY SHARES OF COMMON  STOCK  ISSUABLE  UPON THE
      EXERCISE OF THIS WARRANT HAVE BEEN REGISTERED  UNDER THE SECURITIES ACT OF
      1933, AS AMENDED,  AND THE RULES AND  REGULATIONS  PROMULGATED  THEREUNDER
      (THE  "SECURITIES  ACT").  THIS WARRANT AND THE COMMON STOCK ISSUABLE UPON
      EXERCISE OF THIS WARRANT

      EXEMPT FROM SUCH REGISTRATION.

      Upon  exercise  of  the  Warrant,   SELLER  shall  issue  a  common  stock
certificate  without such legend to the holder of such Warrant provided that the
Registration  Statement  covering the Common Shares  underlying  the Warrant has
been  declared  effective  by the SEC  and  remains  in  effect  at the  date of
exercise.

      (v) BUYER  acknowledges  that SELLER or any transfer agent of SELLER shall
register  the  transfer or exchange of any of the  Preferred  Shares or Warrants
only upon receipt of the respective (A) certificate(s) evidencing such Preferred
Shares with the transfer notice set forth thereon  appropriately  completed,  or
(B) the  Warrants,  and upon  receipt  in  writing  from the  transferee  or the
recipient of such Preferred  Shares or Warrants in such transfer or exchange (as
the case may be) of a certificate setting forth the representations in Paragraph
2 hereof;

      (vi)  If  BUYER  is  acquiring  any  Preferred  Shares,  Warrants  or  the
underlying Shares as fiduciary or agent for one or more institutional  accounts,
BUYER  represents  that it has sole  investment  discretion with respect to each
such account and that it has full power to make the  foregoing  acknowledgments,
representations and agreements on behalf of each such institutional account;

      (vii) BUYER  acknowledges  that SELLER and others will rely upon the truth
and accuracy of the foregoing  acknowledgments,  representations  and agreements
and further agrees that if, prior to the closing,  any of such  acknowledgments,
representations and agreements made by BUYER are no longer accurate,  BUYER will
promptly notify SELLER;

      (viii) BUYER has received  all  information  necessary to make an informed
business  decision  with  respect  to an  investment  in the  Preferred  Shares,
Warrants and  underlying  Shares,  including but not limited to SELLER'S  latest
Form 10-K, all Forms 10- Q and 8-K filed thereafter, and the Proxy Statement for
its latest fiscal year  (collectively,  the "Public  Documents") and the Private
Placement  Memorandum  prepared by SELLER.  Neither the Public Documents nor the
Private Placement  Memorandum include any untrue statement of a material fact or
omit to state  any  material  fact  necessary  in  order to make the  statements
contained therein, in light of the circumstances under which they were made, not
misleading;

      (ix)  This  Agreement  has been duly  authorized,  validly  executed,  and
delivered on behalf of BUYER and is a valid and binding agreement enforceable in





<PAGE>

Page 5



accordance  with its  terms,  subject  to  general  principles  of equity and to
bankruptcy  or  other  laws  affecting  the  enforcement  of  creditors'  rights
generally; and

      (x) BUYER has not  engaged  and agrees not to engage in any short sales or
other  hedging  transactions  with respect to SELLER'S  common  stock;  provided
however,  that  BUYER may enter  into such  transactions  involving  a number of
common  shares not to exceed the number of Common  Shares or Warrant  Shares for
which a notice  of  conversion  or  Election  to  Purchase  with  regard  to the
Preferred Shares or Warrants, respectively, has been submitted to SELLER;

      (xi) BUYER  understands  and  acknowledges  that SELLER  currently  has an
insufficient  number of  authorized  common  shares  available for issuance upon
conversion  of the  Preferred  Shares and  exercise  of the  Warrants  purchased
hereunder. BUYER understands that SELLER has agreed to take all steps reasonably
necessary to gain such  approval as may be required to issue  additional  common
shares to BUYER in  accordance  with the terms of this  Agreement.  In the event
such approval is not obtained from  SELLER'S  shareholders,  SELLER shall pay to
BUYER Three Hundred  Thousand  U.S.  Dollars  ($300,000) in accordance  with the
terms of the Escrow Agreement.


3.    SELLER'S REPRESENTATIONS AND AGREEMENTS

SELLER represents, warrants and agrees as follows:

      (i)  SELLER  has  not  conducted  any  general   solicitation  or  general
advertising (as defined in Regulation D) with respect to any of its securities;

      (ii) SELLER  acknowledges that it currently has an insufficient  number of
authorized common shares available for issuance upon conversion of the Preferred
Shares and exercise of the  Warrants  purchased  hereunder  and  represents  and
warrants  that its Board of Directors  has approved an increase in the number of
SELLER'S authorized common shares from 50 million to 75 million. SELLER warrants
and  agrees to take all  steps  reasonably  necessary  to gain  approval  by the
stockholders  of SELLER of such  increase in SELLER'S  authorized  common shares
from fifty million  (50,000,000)  to  seventy-five  million  (75,000,000)  on or
before  February 28, 1997 and, if such  approval is obtained,  to deliver to the
BUYER a copy of an Amendment to the Certificate of Incorporation  of SELLER,  in
the form annexed as Exhibit "A" to the Escrow  Agreement  (the  "Certificate  of
Amendment"),  certified  as filed  with the  Secretary  of State of the State of
Delaware, not later than March 5, 1997. In the event that, on or before March 5,
1997,  SELLER'S  shareholders  fail to  approve  the  increase  in the number of






<PAGE>


Private Sec. Sub. Agreement:  Viragen, Inc./P.R.I.F., L.P.
December 31, 1996
Page 6



SELLER'S  authorized  common stock from 50 million to 75 million  shares,  or if
SELLER does not comply with its obligations  pursuant to Section 3 of the Escrow
Agreement,  SELLER  shall  pay to BUYER  Three  Hundred  Thousand  U.S.  Dollars
($300,000) ("Commitment Fee").

      (iii) The Preferred Shares, the Warrants,  and the Shares, when issued and
delivered,  will be duly and  validly  authorized  and  issued,  fully-paid  and
nonassessable, and will not subject the holders thereof to personal liability by
reason of being such holders. In addition,  the Preferred Shares,  Warrants, and
Shares,  when  issued  and  delivered,  shall  be free and  clear of any  liens,
encumbrances,  charges, or adverse claims of any nature whatsoever. There are no
preemptive  rights of any  shareholder  of SELLER with respect to the  Preferred
Shares, Warrants, and the Shares;

      (iv)  This  Agreement  has been  duly  authorized,  validly  executed  and
delivered on behalf of SELLER and is a valid and binding agreement in accordance
with its terms,  subject to general  principles  of equity and to  bankruptcy or
other laws affecting the enforcement of creditors' rights generally;

      (v) The execution and delivery of this Agreement and the  consummation  of
the issuance of the  Preferred  Shares,  the Warrants,  and the Shares,  and the
transactions contemplated by this Agreement do not and will not conflict with or
result in a breach by SELLER of any of the terms or provisions of, or constitute
a default under, the articles of incorporation (or charter) or bylaws of SELLER,
or any  indenture,  mortgage,  deed of  trust  or other  material  agreement  or
instrument to which SELLER is a party or by which it or any of its properties or
assets are bound, or any existing  applicable  decree,  judgment or order of any
court,  federal  or  state  regulatory  body,  administrative  agency  or  other
governmental  body having  jurisdiction  over SELLER or any of its properties or
assets;

      (vi) No authorization,  approval or consent of or filing with any federal,
state or local  governmental  body of the United States is legally  required for
the issuance and sale of the Shares as contemplated by this Agreement, except as
noted in Section 3(ii) above;

      (vii)  The  information  provided  by or on  behalf of SELLER to BUYER and
referred  to in Section  2(viii) of this  Agreement  does not contain any untrue
statement  of a material  fact or omit to state any material  fact  necessary in
order to make the statements  therein,  in the light of the  circumstance  under
which they are made,  not  misleading.  Since June 30,  1996,  there has been no
material adverse development in the business, properties,  operations, financial
condition  or  results  of  operations  of SELLER,  except as  disclosed  in the
documents referred to in Section 2(viii) hereof;






<PAGE>


Private Sec. Sub. Agreement:  Viragen, Inc./P.R.I.F., L.P.
December 31, 1996
Page 7


      (viii)  SELLER  will  issue  one or  more  certificates  representing  the
Preferred  Shares in the name of BUYER in such  denominations to be specified by
BUYER prior to closing.  The Preferred  Shares will bear the restrictive  legend
specified in Section 2(iii) of this Agreement.  SELLER further  warrants that no
instructions  other than these  instructions  and stop transfer  instructions to
give effect to Section 2(i) hereof will be given to the transfer  agent and also
warrants  that the  Shares  shall  otherwise  be  transferable  on the books and
records of SELLER as and to the extent  provided in this  Agreement,  subject to
compliance with Federal and State securities laws. Nothing in this Section shall
affect  in any  way  BUYER'S  obligations  and  agreement  to  comply  with  all
applicable securities laws upon resale of the Shares.

      (ix) Prior to or at  Closing,  SELLER will issue a Common  Stock  Purchase
Warrant Certificate  ("Warrant  Certificate")  entitling BUYER to purchase Three
Hundred  Seventy-Five  Thousand (375,000) shares of SELLER'S common stock, which
Warrant  certificate  shall be  delivered  to the Escrow  Agent at Closing.  The
Warrants  shall be  exercisable  at Six Dollars  ($6.00) U.S. per Warrant Share,
subject to adjustment pursuant to Section 5(iii) hereof. The Warrant Certificate
will bear the restrictive  legend  specified in Section 2(iv) of this Agreement.
SELLER further warrants that no instructions  other than these  instructions and
stop  transfer  instructions  to give effect to Section  2(i)  hereof,  prior to
registration of the resale of the Shares under the Securities Act, will be given
to the  transfer  agent and also  warrants  that the Shares  shall  otherwise be
transferable on the books and records of SELLER as and to the extent provided in
this Agreement,  subject to compliance with Federal and State  securities  laws.
Nothing  in this  Section  shall  affect  in any  way  BUYER'S  obligations  and
agreement  to comply  with all  applicable  securities  laws upon  resale of the
Shares.

      (x) SELLER warrants that it currently meets the  requirements for filing a
Registration  Statement  on Form S-3,  and that it will make timely  filings and
take all other steps necessary to maintain such  eligibility  until such time as
BUYER has fully converted its Preferred Shares and Warrants acquired pursuant to
this Agreement.


4.       CONVERSION AND OTHER TERMS.

      (i) The Preferred  Shares will be convertible at the option of BUYER on or
after the day following the date that the registration  statement for the Shares
underlying the Preferred Shares and Warrants has been declared  effective by the
SEC (the "Conversion Period"), at eighteen percent (18%) off the average closing
bid price of SELLER'S  common stock,  as reported by Bloomberg,  L.P.,  over the







<PAGE>


Private Sec. Sub. Agreement:  Viragen, Inc./P.R.I.F., L.P.
December 31, 1996
Page 8


five-day  trading  period  ending on the  trading day prior to  conversion  (the
"Conversion Price").  Notwithstanding the above, the Conversion Price may not be
more than Seven Dollars  ($7.00) U.S. per Common Share nor less than Two Dollars
($2.00) U.S. per Common Share (the "Floor");  provided,  however, that BUYER may
not convert any Preferred Shares during the Conversion  Period if the Conversion
Price (a)  averaged  over any  consecutive  5-trading  day  period or (b) on any
single trading day, as averaged over the prior 5-day trading period, falls below
the Floor (each such period of 5 consecutive  days so used for determining  such
average being a  "Nonconverting  Period").  Upon occurrence of the  twenty-first
Nonconverting  Period,  BUYER shall  thereafter  have the right to convert,  and
SELLER will be obligated upon receipt of a notice of conversion from BUYER,  for
which the applicable  Conversion  Price would be below the Floor,  to (a) pay to
BUYER  cash  equal to the amount  originally  paid by BUYER for the  outstanding
Preferred Shares, plus ten percent (10%) of such amount (the "Cash-Out Option"),
or (b)  convert  the  outstanding  Preferred  Shares held by BUYER into the full
number of Common  Shares to which  BUYER  would be  entitled  at the  Conversion
Price,  irrespective of the Floor (the "Stock Conversion  Option").  SELLER must
notify BUYER of its intent with regard to such  options  within one (1) business
day of receipt of the notice of conversion, and must effect such cash payment or
stock conversion  within three (3) business days following actual receipt of the
notice of conversion.

      (ii) Any Preferred Shares remaining  outstanding on the second anniversary
of the Closing, as defined in Section 6 hereof, will be automatically  converted
into Common Shares on such date.  The Preferred  Shares shall have a liquidation
preference  over the Common  Shares in the event of any  liquidation  or sale of
SELLER.  The Preferred Shares will pay a dividend of six percent (6%) per annum,
payable quarterly in arrears,  in cash. Upon conversion,  any accrued but unpaid
dividends will be added to the stated value of the Preferred Shares converted.

      (iii) In the event SELLER elects the Stock Conversion Option as defined in
Section  4(i) above,  SELLER  shall use its best efforts to issue and deliver to
BUYER a  certificate  or  certificates  for the number of Common Shares to which
BUYER shall be entitled within three (3) business days after BUYER has fulfilled
all  conditions  required for  conversion  as set forth in this  Agreement  (the
"Deadline"), which conditions shall include actual receipt by SELLER of the duly
executed notice of conversion and the original Preferred Shares being converted,
with an  executed  stock  power,  and any other  items  reasonably  required  by
SELLER'S transfer agent.  SELLER understands that a delay in the issuance of the
Common  Shares beyond the Deadline  could result in economic  loss to BUYER.  As
compensation to BUYER for such loss, and not as a penalty,  SELLER agrees to pay
liquidated  damages to BUYER for late delivery of Common Shares upon  conversion
in the amount of one percent (1%) of the requested  conversion  amount, per day,
beginning  on  day  after  the  Deadline  in the event the Common Shares are not





<PAGE>


Private Sec. Sub. Agreement:  Viragen, Inc./P.R.I.F., L.P.
December 31, 1996
Page 9




delivered  within seven (7) business  days after the Deadline.  Said  liquidated
damages  shall accrue each day through the date the Common  Shares are delivered
to BUYER  upon  conversion,  and shall be paid by wire  transfer  to an  account
designated  by BUYER upon the earlier to occur of (i)  delivery of the Shares to
BUYER,  or (ii) each weekly  anniversary  of the Deadline.  Nothing herein shall
waive  SELLER'S  obligations  to deliver  Common  Shares upon  conversion of the
Preferred  Shares or exercise of the Warrants or limit  BUYER'S  right to pursue
actual damages for SELLER'S  failure to issue and deliver Common Shares to Buyer
in accordance with the terms of this Agreement,  the Preferred  Shares,  and the
Warrants.

      (iv) SELLER  agrees that, in addition to any other  remedies  which may be
available to BUYER,  in the event SELLER fails for any reason to effect delivery
to BUYER of  certificates  representing  Common Shares within seven (7) business
days following  actual  receipt by SELLER of a notice of  conversion,  BUYER may
revoke the notice of conversion by delivering a notice of such effect to SELLER,
whereupon SELLER and BUYER shall each be restored to their respective  positions
immediately prior to delivery of such notice of conversion.

      (v)   See Page 9A attached hereto and made a part hereof.

5.    PROSPECTIVE FINANCINGS AND LIMITATIONS THEREON.

      (i) SELLER agrees not to issue any additional  shares of its common stock,
nor securities  convertible  into,  exchangeable for or otherwise  entitling the
holders to acquire shares of its common stock (each a "Prospective  Financing"),
for a period of one hundred  eighty (180)  calendar  days after the Closing,  as
defined in Section 6 hereof, other than pursuant to:

            (a)   compensating stock options or stock-based plans;

            (b)   binding agreements in effect on the Closing;

            (c)   any financing  agreements of $5,000,000  U.S.  Dollars or less
                  entered into by and between SELLER and State Capital  Markets,
                  Ltd.; or

            (d)   any financing arrangement related to:

                     1. the American Red Cross ("ARC");
                     2. Independent (non-ARC) or governmental
                        blood collection, blood fractionation, or blood

                     services/management   entities,  and  independent  blood
                     industry  trade  entities  in the  United  States;  3.  the
                     Canadian Red Cross  ("CRC");  4.  Independent  (non-CRC) or
                     governmental blood collection entities, blood fractionation
                     entities,  or  blood   services/management   entities,  and
                     independent blood industry trade entities in Canada.

      (ii) If,  prior to 180  days  following  Closing,  SELLER  enters  into an
agreement for any Prospective  Financing other than as set forth in Section 5(i)
hereof,  BUYER shall  receive,  for no additional  consideration,  warrants (the
"Prospective  Financing Warrants") to purchase an additional number of shares of
SELLER'S common stock equal to:

            (a)   100,000 common shares, for Prospective  Financings  contracted
            within 30 days of Closing;

            (b) 66,000 common shares, for Prospective  Financings  contracted on
            or after 31 days from Closing but within 60 days following  Closing;
            and

            (c) 33,000 common shares, for Prospective  Financings  contracted on
            or after 61 days from Closing but within 90 days following Closing.

In  addition,  the  provisions  of this  Section  5(ii) shall apply in the event
Seller enters into an agreement for any  Prospective  Financing  described under
Section 5(i)(d) above. The Prospective  Financing  Warrants issuable pursuant to
this Section 5(ii) shall be in the same form and shall be  exercisable  upon the
same terms and conditions as the Warrants as set forth in this Agreement and the
form of Common Stock Purchase Warrant  Certificate  annexed hereto as Exhibit B,
provided  however,  that all Prospective  Financing  Warrants issued pursuant to
this Section 5(ii) shall have an exercise price of $1.00 U.S.

      (iii) If SELLER enters into an agreement for any Prospective  Financing in
an amount  less than or equal to  $15,000,000  U.S.,  other than as set forth in
clauses  (a),  (b) or (c) of Section  5(i)  hereof,  the  exercise  price of the
Warrants and all Prospective  Financing  Warrants  issuable  pursuant to Section
5(iv) hereof shall be reduced as follows:

            (a)   for any Prospective Financings contracted within 90 days of






<PAGE>

            Closing, the exercise price of the Warrants shall be $1.00 U.S.;

            (b) for Prospective  Financings  contracted on or after 90 days from
            Closing but before 120 days from Closing, the exercise price of
            the Warrants shall be $2.00 U.S.;

            (c) for Prospective  Financings contracted on or after 120 days from
            Closing but before 150 days from Closing, the exercise price of
            the Warrants shall be $3.00 U.S.;

            (d) for Prospective  Financings contracted on or after 150 days from
            Closing but before 180 days from Closing, the exercise price of
            the Warrants shall be $4.00 U.S.; and

            (e) for  Prospective  Financings  contracted  on after 180 days from
            Closing, the exercise price of the Warrants shall be $6.00 U.S.

      (iv) If, prior to 180 days following Closing, SELLER enters into agreement
for any Prospective  Financing in an amount greater than $15,000,000 U.S., other
than as set forth in clauses (a), (b) or (c) of Section 5(i) hereof,  then BUYER
shall  receive,  for  no  additional  consideration,  and  in  addition  to  the
Prospective Financing Warrants,  warrants (the "Additional Prospective Financing
Warrants") to purchase an additional  Twenty Five  Thousand  (25,000)  shares of
SELLER'S common stock per each $1,000,000 (or portion thereof) U.S. by which the
amount of such  Prospective  Financing  exceeds  $15,000,000 U.S. The Additional
Prospective  Financing Warrants issuable pursuant to this Section 5(iv) shall be
exercisable  upon  the same  terms  and  conditions  as the  Warrants,  provided
however,  that  the  exercise  price  of the  Additional  Prospective  Financing
Warrants  issuable  pursuant to this  Section  5(iv) shall be the same  exercise
price of the Warrants as shall be determined by Section 5(iii) hereof.

      (v) SELLER  warrants  and agrees that it will  promptly  notify BUYER upon
entering into a contract for any Prospective  Financing,  and will provide BUYER
with the amount, completion date, and terms of such Prospective Financing.

upon exercise of any Prospective  Financing Warrants issued hereunder will, upon
delivery to the BUYER, be duly and validly authorized and issued, fully-paid and
non-assessable, and registered for resale with the SEC.

                        REGISTRATION RIGHTS AGREEMENT




      THIS REGISTRATION  RIGHTS  AGREEMENT,  dated as of December 31, 1996 (this
"Agreement"),  is made by and among Viragen,  Inc. a Delaware  corporation  (the
"Company"),  and the person  named on the  signature  page hereto  (referred  to
herein as "Initial Investor" or "Buyer").

                            W I T N E S S E T H :

            WHEREAS,  in  connection  with the Private  Securities  Subscription
      Agreement, dated as of December 31, 1996, between the Initial Investor and
      the Company (the "Subscription  Agreement"),  the Company has agreed, upon

      ("Warrants")  and  shares of  Preferred  Stock (the  "Preferred  Shares"),
      convertible  into  shares of Common  Stock,  $.01 par value  (the  "Common

            WHEREAS,  to induce the Initial  Investor to execute and deliver the
      Subscription  Agreement,   the  Company  has  agreed  to  provide  certain
      registration rights under the Securities Act of 1933, as amended,  and the
      rules  and  regulations  thereunder,  or  any  similar  successor  statute
      (collectively, the "Securities Act"), and applicable state securities laws
      with respect to the shares of Common Stock underlying the Preferred Shares
      and Warrants;

            NOW,  THEREFORE,  in  consideration  of the  premises and the mutual
      covenants contained herein and other good and valuable consideration,  the
      receipt and sufficiency of which are hereby acknowledged,  the Company and
      the Initial Investor hereby agree as follows:

      the Company,  and, when requested by the Initial  Investor or any Investor
      pursuant to Section 2 hereof,  shall (A) be  reasonably  acceptable to the
      holders  of a  majority  of  the  Registrable  Securities  to  which  such
      registration  relates, and (B) shall permit the disposition of Registrable
      Securities in accordance with the intended method or methods  specified in
      the  Investor's  request for such  registration,  and the  declaration  or
      ordering of  effectiveness  of such  Registration  Statement by the United

            (c) Capitalized  terms used herein and not otherwise  defined herein
      shall  have  the  respective   meanings  set  forth  in  the  Subscription
      Agreement.

            2.    REGISTRATION.

            (A)  PAYMENTS BY THE COMPANY.  The Company must file a  Registration
      Statement with the SEC within 20 business days of the Closing,  as defined
      in Section 6 of the Subscription  Agreement,  registering the Common Stock
      underlying the Preferred Shares and Warrants for resale. The Company shall
      use its best efforts to have the Registration Statement declared effective
      as soon as possible after filing and shall keep the Registration Statement
      effective  pursuant  to Rule 415 at all times  until such date as is three
      (3)  years  after the date the  Registration  Statement  is first  ordered
      effective  by the SEC. In the event the Company  receives a "no action" or
      "no review" letter from the SEC with regard to the Registration Statement,
      the Company shall cause the Registration  Statement to be effective within
      five (5) business days of the receipt of such letter.  If the Registration
      Statement  covering the Registrable  Securities is not effective within 75
      



<PAGE>


Viragen, Inc./P.R.I.F., L.P. Registration Rights Agreement

Page 3

      days after the Closing,  then the Company  will make  payments to Buyer in
      such  amounts  and at such times as shall be  determined  pursuant to this
      Section 2(a). The amount to be paid by the Company to the Buyer shall be a
      use of funds  fee  equal to 1% of the  subscription  price  for the  first
      fifteen  (15) days  following  said 75-day  period,  and 2% for the 30-day
      period  following  said  90-day  period,  which  use of funds fee shall be
      prorated on a daily basis. Thereafter,  the Company shall pay a penalty to
      Buyer  equal  to 3% of the  subscription  price  for each  30-day  period,
      prorated on a daily basis,  until the  Registration  Statement is declared
      effective  by the SEC.  Said penalty  shall not exceed the maximum  amount
      allowed by law. The amounts  referred to in this section  shall be paid by
      the Company  within  five  business  days after the end of the  applicable
      period  beginning  with  the 15 day  period  beginning  on the  first  day
      following  the 75 -day  period  referred  to above and shall be payable in
      cash.

            (B)  PIGGY-BACK  REGISTRATIONS.  If at any  time the  Company  shall
      determine  to  prepare  and  file  with the SEC a  Registration  Statement
      relating  to an  offering,  for its own  account or the  account of others
      under the Securities Act, of any of its equity  securities,  other than on
      Form  S-4 or  Form  S-8 or  their  then  equivalents  relating  to  equity
      securities to be issued solely in connection  with any  acquisition of any
      entity or business or equity securities  issuable in connection with stock
      option or other  employee  benefit  plans,  the Company shall send to each
      Investor,  who is entitled to registration rights under this Section 2(b),
      written notice of such determination and, if within twenty (20) days after
      receipt of such notice,  such  Investor  shall so request in writing,  the
      Company  shall include in such  Registration  Statement all or any part of
      the Registrable Securities such Investor requests to be registered, except
      that if, in  connection  with any  underwritten  public  offering  for the
      account of the Company the managing  underwriter(s) thereof shall impose a
      limitation  on the number of shares of Common  Stock which may be included
      in the Registration  Statement because, in such underwriter(s)'  judgment,
      such  limitation  is necessary to effect an orderly  public  distribution,
      then the  Company  shall be  obligated  to  include  in such  Registration
      Statement only such limited portion, if any, of the Registrable Securities
      with respect to which such Investor has requested inclusion hereunder. Any
      exclusion  of  Registrable  Securities  shall be made pro rata  among  the
      Investors seeking to include Registrable Securities,  in proportion to the
      number of Registrable  Securities sought to be included by such Investors;
      provided,  however,  that the Company  shall not  exclude any  Registrable
      Securities   unless  the  Company  has  first  excluded  all   outstanding
      securities  the holders of which are not entitled by right to inclusion of
      securities in such Registration Statement; and provided, further, however,
      that,  after  giving  effect to the  immediately  preceding  proviso,  any
      exclusion of Registrable Securities shall be made pro rata with holders of
      other  securities  having  the right  to  include such securities  in  the




<PAGE>


Viragen, Inc./P.R.I.F., L.P. Registration Rights Agreement   
December 31, 1996
Page 4


      Registration  Statement to the extent such pro rata allotment is permitted
      under the Company's currently existing agreements with such holders of the
      Company's securities.  No right to registration of Registrable  Securities
      under this  Section  2(b)  shall be  construed  to limit any  registration
      required under Section 2(c) hereof.  The  obligations of the Company under
      this  Section  2(b) may be  waived by  Investors  holding  a  majority  in
      interest  of the  Registrable  Securities  and shall  expire (i) after the
      Company  has  afforded  the  opportunity  for the  Investors  to  exercise
      registration  rights  under  this  Section  2(b)  for  two  registrations;
      provided,  however,  that any Investor who shall have had any  Registrable
      Securities  excluded from any  Registration  Statement in accordance  with
      this  Section  2(b)  shall  be  entitled  to  include  in  an   additional
      Registration  Statement filed by the Company the Registrable Securities so
      excluded  or  (ii)  when  all of the  Registrable  Securities  held by any
      Investor may be sold by such Investor  under Rule 144 under the Securities
      Act ("Rule 144") within any three-month period.

            (C) DEMAND REGISTRATION.  If, at any time after the date which is 30
      days  following  the  release of  purchase  price funds from Escrow as set
      forth in the  Subscription  Agreement,  any Investor holding a majority of
      the  Registrable  Securities  shall  notify the Company in writing that it
      intends  to offer  or cause to be  offered  for  public  sale  Registrable
      Securities  held by such  Investor,  the  Company  shall cause such of the
      Registrable  Securities  as  may  be  requested  by  any  Investor  to  be
      registered,  on one occasion only, under the Securities Act and applicable
      state laws as expeditiously  as possible.  Once the right for registration
      of any Registrable  Securities  under this Section 2(c) has been exercised
      by any  Investor,  the  Company  shall  prepare  and  file a  Registration
      Statement covering such Registrable  Securities with the SEC within twenty
      (20) days of the exercise of such registration right.

            (D) If any offering pursuant to a Registration Statement pursuant to
      Section 2(c) above  involves (at the Company's  election) an  underwritten
      offering, the Investors who hold a majority in interest of the Registrable
      Securities  subject to such underwritten  offering shall have the right to
      select one legal counsel and an  investment  banker or bankers and manager
      or managers to administer the offering, which investment banker or bankers
      or manager or managers  shall be reasonably  satisfactory  to the Company.
      The Investors who hold the  Registrable  Securities to be included in such
      underwriting  shall pay all  underwriting  discounts and  commissions  and
      other fees and expenses of such  investment  banker or bankers and manager
      or managers so selected in  accordance  with this Section 2(d) (other than
      fees and expenses relating to registration of Registrable Securities under
      federal or state securities laws which are payable by the Company pursuant
      to Section 5 hereof) with respect to their




<PAGE>


Viragen, Inc./P.R.I.F., L.P. Registration Rights Agreement
December 31, 1996
Page 5


      Registrable  Securities  and the fees and  expenses of such legal  counsel
      selected by the Investors.

            3.  OBLIGATIONS OF THE COMPANY.  In connection with the registration
      of the  Registrable  Securities  and in  addition to the  requirements  of
      Section 2(a) above, the Company shall:

      (a) prepare promptly and file with the SEC promptly (but in no event later
      than 20 days) after a request in  accordance  with  Section  2(c) hereof a
      Registration  Statement  or  Statements  with  respect to all  Registrable
      Securities to be included therein,  and thereafter use its best efforts to
      cause the Registration Statement to become effective as soon as reasonably
      possible  after such  filing.  The  Company  shall  keep the  Registration
      Statement  effective  pursuant to Rule 415 at all times until such date as
      is three years after the date such Registration Statement is first ordered
      effective by the SEC. In any case, any Registration  Statement  (including
      any amendments or supplements thereto and prospectuses  contained therein)
      filed by the Company shall not contain any untrue  statement of a material
      fact or omit to state a material  fact required to be stated  therein,  or
      necessary to make the statements therein, in light of the circumstances in
      which they were made, not misleading.  Subject to the conditions set forth
      in Section  4(a) below,  each  Investor  may notify the Company in writing
      that it wishes to exclude all or a portion of its  Registrable  Securities
      from such Registration Statement. Notwithstanding the foregoing provisions
      of Section 3(a),  if at any time the  Investors  shall be entitled to sell
      all  Registrable  Securities held by them pursuant to Rule 144 promulgated
      under the  Securities  Act or any other  similar rule or regulation of the
      SEC that may at any time permit the  Investors to sell  securities  of the
      Company  to  the  public  without   registration   and  without   imposing
      restrictions  arising under the federal  securities  laws on the purchases
      thereof in a period of three consecutive  months,  then the Company shall,
      so long as it meets the current public  information  requirements  of Rule
      144,  thereafter  no longer be required to maintain  the  registration  of
      Registrable Securities pursuant to this Agreement;

            (b)  prepare  and  file  with  the SEC  such  amendments  (including
      post-effective  amendments) and supplements to the Registration  Statement
      and the prospectus used in connection with the  Registration  Statement as
      may be necessary to keep the Registration Statement effective at all times
      until  such  date as is  three  years  after  the date  such  Registration
      Statement is first ordered  effective by the SEC, and, during such period,
      comply  with the  provisions  of the  Securities  Act with  respect to the
      disposition of all  Registrable  Securities of the Company  covered by the
      Registration  Statement  until  such  time  as  all  of  such  Registrable




<PAGE>

Page 6

      Securities have been disposed of in accordance  with the intended  methods
      of  disposition  by the  seller  or  sellers  thereof  as set forth in the
      Registration Statement;

            (c)  furnish  to each  Investor  whose  Registrable  Securities  are
      included  in the  Registration  Statement,  such  number  of  copies  of a
      prospectus,  including a preliminary  prospectus,  and all  amendments and
      supplements  thereto  and  such  other  documents  as  such  Investor  may
      reasonably   request  in  order  to  facilitate  the  disposition  of  the
      Registrable Securities owned by such Investor;

            (d)  use  reasonable   efforts  to  (i)  register  and  qualify  the
      Registrable  Securities  covered by the Registration  Statement under such
      other  securities or blue sky laws of such  jurisdictions as the Investors
      who hold a  majority  in  interest  of the  Registrable  Securities  being
      offered reasonably  request,  (ii) prepare and file in those jurisdictions
      such amendments  (including  post-effective  amendments) and  supplements,
      (iii)  take such  other  actions  as may be  necessary  to  maintain  such
      registrations and qualifications in effect at all times until such date as
      is the earlier of three years after the date such  Registration  Statement
      is first ordered  effective by the SEC or is three years after the Initial
      Investor  acquired the Shares and (iv) take all other  actions  reasonably
      necessary or advisable to qualify the  Registrable  Securities for sale in
      such  jurisdictions;  provided,  however,  that the  Company  shall not be
      required in connection  therewith or as a condition thereto to (I) qualify
      to do  business  in any  jurisdiction  where it  would  not  otherwise  be
      required to qualify but for this  Section  3(d),  (II)  subject  itself to
      general taxation in any such jurisdiction, (III) file a general consent to
      service of process in any such jurisdiction, (IV) provide any undertakings
      that cause more than nominal  expense or burden to the Company or (V) make
      any  change in its  charter  or  by-laws,  which in each case the Board of
      Directors of the Company  determines to be contrary to the best  interests
      of the Company and its stockholders;

            (e) in the event  Investors  who hold a majority  in interest of the
      Registrable  Securities being offered in the offering select  underwriters
      for the  offering,  enter  into  and  perform  its  obligations  under  an
      underwriting  agreement,  in usual and customary form, including,  without
      limitation,  customary indemnification and contribution obligations,  with
      the managing underwriter of such offering;

            (f) as promptly as  practicable  after becoming aware of such event,
      notify each Investor who holds Registrable  Securities being sold pursuant
      to such  registration  of the  happening of any event of which the Company
      has  knowledge,  as a  result  of which  the  prospectus  included  in the
      Registration Statement, as then in effect, includes an untrue statement of

      a material  fact or omits to state a material  fact  required to be stated
      therein  or  necessary  to make the  statements  therein,  in light of the
      circumstances under which they were made, not misleading, and use its best
      efforts  promptly to prepare a supplement or amendment to the Registration
      Statement  to correct such untrue  statement  or  omission,  and deliver a
      number of copies of such  supplement or amendment to each Investor as such
      Investor may reasonably request;

            (g) as promptly as  practicable  after becoming aware of such event,
      notify each Investor who holds Registrable  Securities being sold pursuant
      to such  registration (or, in the event of an underwritten  offering,  the
      managing  underwriters)  of the  issuance  by the SEC of any stop order or
      other suspension of  effectiveness  of the  Registration  Statement at the
      earliest possible time;

            (h)  permit  a  single  firm  of  counsel   designated   as  selling
      stockholders'  counsel by the Investors who hold a majority in interest of
      the  Registrable  Securities  being sold pursuant to such  registration to
      review the  Registration  Statement  and all  amendments  and  supplements
      thereto a  reasonable  period of time prior to their  filing with the SEC,
      and shall not file any document in a form to which such counsel reasonably
      objects;

            (i) make  generally  available  to its  security  holders as soon as
      practical,  but not later  than  ninety  (90) days  after the close of the
      period covered thereby,  an earnings statement (in form complying with the
      provisions of Rule 158 under the Securities  Act) covering the fiscal year
      period  beginning  not later  than the first day of the  Company's  fiscal
      quarter next following the date of the Registration Statement;

            (j) at the request of the  Investors who hold a majority in interest
      of the Registrable  Securities  being sold pursuant to such  registration,
      furnish  on the date  that  Registrable  Securities  are  delivered  to an
      underwriter for sale in connection with the  Registration  Statement (i) a
      letter, dated such date, from the Company's  independent  certified public
      accountants in form and substance as is  customarily  given by independent
      certified  public  accountants to underwriters  in an underwritten  public
      offering,  addressed to the underwriters;  and (ii) an opinion, dated such
      date,  from  counsel   representing  the  Company  for  purposes  of  such
      Registration  Statement,  in form and substance as is customarily given in
      an  underwritten  public  offering,  addressed  to  the  underwriters  and
      Investors;

            (k) make available for inspection by any Investor whose  Registrable
      Securities are being sold pursuant to such  registration,  any underwriter
      participating in any disposition  pursuant to the Registration  Statement,

      and any attorney,  accountant or other agent retained by any such Investor
      or underwriter (collectively,  the "Inspectors"),  all pertinent financial
      and other  records,  pertinent  corporate  documents and properties of the
      Company (collectively, the "Records"), as shall be reasonably necessary to
      enable each  Inspector to exercise its due diligence  responsibility,  and
      cause the  Company's  officers,  directors  and  employees  to supply  all
      information  which any  Inspector may  reasonably  request for purposes of
      such due diligence;  provided,  however, that each Inspector shall hold in
      confidence  and shall not make any  disclosure  (except to an Investor) of
      any Record or other information which the Company determines in good faith
      to be  confidential,  and of which  determination  the  Inspectors  are so
      notified,  unless (i) the disclosure of such Records is necessary to avoid
      or correct a misstatement or omission in any Registration Statement,  (ii)
      the  release of such  Records is ordered  pursuant  to a subpoena or other
      order from a court or government  body of competent  jurisdiction or (iii)
      the  information in such Records has been made generally  available to the
      public  other  than by  disclosure  in  violation  of  this  or any  other
      agreement.  The Company shall not be required to disclose any confidential
      information  in such  Records  to any  Inspector  until  and  unless  such
      Inspector shall have entered into confidentiality  agreements (in form and
      substance  satisfactory  to the  Company)  with the Company  with  respect
      thereto,  substantially  in the form of this Section  3(k).  Each Investor
      agrees that it shall,  upon  learning  that  disclosure of such Records is
      sought in or by a court or governmental body of competent  jurisdiction or
      through  other  means,  give  prompt  notice to the  Company and allow the
      Company,  at its  expense,  to  undertake  appropriate  action to  prevent
      disclosure  of, or to obtain a protective  order for,  the Records  deemed
      confidential.  The Company shall hold in confidence and shall not make any
      disclosure of information  concerning an Investor  provided to the Company
      pursuant to Section 4(e) hereof unless (i) disclosure of such  information
      is  necessary to comply with federal or state  securities  laws,  (ii) the
      disclosure  of such  information  is  necessary  to  avoid  or  correct  a
      misstatement or omission in any Registration Statement,  (iii) the release
      of such  information is ordered pursuant to a subpoena or other order from
      a court  or  governmental  body of  competent  jurisdiction  or (iv)  such
      information has been made generally  available to the public other than by
      disclosure in violation of this or any other agreement. The Company agrees
      that  it  shall,   upon  learning  that  disclosure  of  such  information
      concerning an Investor is sought in or by a court or governmental  body of
      competent  jurisdiction or through other means, give prompt notice to such
      Investor,  at its  expense,  to  undertake  appropriate  action to prevent
      disclosure of, or to obtain a protective order for, such information;

            (l) use its best  efforts  either to (i)  cause all the  Registrable
      Securities  covered  by  the  Registration  Statement  to be  listed  on a





<PAGE>

      national  securities  exchange,  which shall include the Nasdaq  Small-Cap
      Market,  and on each  additional  national  securities  exchange  on which
      similar  securities  issued by the Company are then listed, if any, if the
      listing of such  Registrable  Securities is then permitted under the rules
      of  such  exchange,  or (ii)  secure  designation  of all the  Registrable
      Securities covered by the Registration Statement as a National Association
      of Securities  Dealers Automated  Quotations  System ("Nasdaq")  "national
      market  system  security"  within the  meaning of Rule  11Aa2-1 of the SEC
      under the  Securities  Exchange  Act of 1934,  as amended  (the  "Exchange
      Act"),  and the  quotation  of the  Registrable  Securities  on the Nasdaq
      National  Market  System or, if,  despite the  Company's  best  efforts to
      satisfy the preceding  clause (i) or (ii), the Company is  unsuccessful in
      satisfying  the  preceding  clause  (i) or (ii),  to secure  listing  on a
      national  securities  exchange or Nasdaq  authorization  and quotation for
      such  Registrable  Securities and,  without limiting the generality of the
      foregoing,  to arrange for at least two market makers to register with the
      National  Association of Securities  Dealers,  Inc.  ("NASD") as such with
      respect to such Registrable Securities;

            (m) provide a transfer  agent and  registrar,  which may be a single
      entity,  for the Registrable  Securities not later than the effective date
      of the Registration Statement;

            (n) cooperate  with the Investors  who hold  Registrable  Securities
      being  sold and the  managing  underwriter  or  underwriters,  if any,  to
      facilitate   the  timely   preparation   and   delivery  of   certificates
      representing   Registrable   Securities   to  be  sold   pursuant  to  the
      denominations  or amounts as the case may be, and registered in such names
      as the managing underwriter or underwriters,  if any, or the Investors may
      reasonably request; and

            (o) take all other  reasonable  actions  necessary  to expedite  and
      facilitate  disposition  by the  Investor  of the  Registrable  Securities
      pursuant to the Registration Statement.

            4. OBLIGATIONS OF THE INVESTORS. In connection with the registration
      of the  Registrable  Securities,  the  Investors  shall have the following
      obligations:

            (a) It shall be a  condition  precedent  to the  obligations  of the
      Company to take any action pursuant to this Agreement with respect to each
      Investor that such Investor shall furnish to the Company such  information
      regarding itself,  the Registrable  Securities held by it and the intended
      method of disposition of the Registrable Securities held by it as shall be
      reasonably   required  to  effect  the  registration  of  the  Registrable
    




<PAGE>


Viragen, Inc./P.R.I.F., L.P. Registration Rights Agreement
December 31, 1996
Page 10

      Securities  and shall  execute  such  documents  in  connection  with such
      registration as the Company may reasonably  request. At least fifteen (15)
      days  prior  to the  first  anticipated  filing  date of the  Registration
      Statement,  the Company shall notify each Investor of the  information the
      Company requires from each such Investor (the "Requested  Information") if
      such Investor elects to have any of such Investor's Registrable Securities
      included in the Registration  Statement.  If within five (5) business days
      prior to the  filing  date the  Company  has not  received  the  Requested
      Information  from an  Investor  (a  "Non-Responsive  Investor"),  then the
      Company may file the Registration  Statement without including Registrable
      Securities of such Non-Responsive Investor;

            (b) Each Investor by such  Investor's  acceptance of the Registrable
      Securities agrees to cooperate with the Company as reasonably requested by
      the  Company  in  connection  with  the  preparation  and  filing  of  the
      Registration  Statement  hereunder,  unless such Investor has notified the
      Company in  writing of such  Investor's  election  to exclude  all of such
      Investor's Registrable Securities from the Registration Statement;

            (c) In the event  Investors  holding a majority  in  interest of the
      Registrable  Securities being registered  determine to engage the services
      of an  underwriter,  each  Investor  agrees to enter into and perform such
      Investor's  obligations  under an  underwriting  agreement,  in usual  and
      customary form, including,  without limitation,  customary indemnification
      and  contribution  obligations,  with  the  managing  underwriter  of such
      offering and take such other actions as are  reasonably  required in order
      to expedite or facilitate the disposition of the  Registrable  Securities,
      unless  such  Investor  has  notified  the  Company  in  writing  of  such
      Investor's  election  to  exclude  all  of  such  Investor's   Registrable
      Securities from the Registration Statement;

            (d) Each Investor  agrees that,  upon receipt of any notice from the
      Company of the  happening  of any event of the kind  described  in Section
      3(f) or 3(g), such Investor will  immediately  discontinue  disposition of
      Registrable  Securities  pursuant to the Registration  Statement  covering
      such Registrable Securities until such Investor's receipt of the copies of
      the  supplemented  or amended  prospectus  contemplated by Section 3(f) or
      3(g) and, if so directed by the Company,  such  Investor  shall deliver to
      the Company (at the expense of the Company) or destroy (and deliver to the
      Company a  certificate  of  destruction)  all  copies  in such  Investor's
      possession, of the prospectus covering such Registrable Securities current
      at the time of receipt of such notice; and

            (e) No Investor may  participate  in any  underwritten  registration
      hereunder  unless  such  Investor  (i)  agrees  to  sell  such  Investor's
 



<PAGE>


Viragen, Inc./P.R.I.F., L.P. Registration Rights Agreement
December 31, 1996
Page 11

      Registrable   Securities  on  the  basis  provided  in  any   underwriting
      arrangements  approved by the Investors entitled hereunder to approve such
      arrangements,  (ii) completes and executes all  questionnaires,  powers of
      attorney,   indemnities,   underwriting  agreements  and  other  documents
      reasonably required under the terms of such underwriting  arrangements and
      (iii) agrees to pay its pro rata share of all  underwriting  discounts and
      commissions  and other fees and  expenses  of  investment  bankers and any
      manager  or  managers  of such  underwriting  and  legal  expenses  of the
      underwriter applicable with respect to its Registrable Securities, in each
      case to the extent not  payable by the  Company  pursuant  to the terms of
      this Agreement.

            5. EXPENSES OF REGISTRATION.  All expenses (other than  underwriting
      discounts  and  commissions  and other  fees and  expenses  of  investment
      bankers and other than brokerage  commissions) incurred in connection with
      registrations, filings or qualifications pursuant to Section 3, including,
      without  limitation,  all registration,  listing and qualifications  fees,
      printers and accounting fees and the fees and disbursements of counsel for
      the Company,  shall be borne by the Company;  provided,  however, that the
      Investors shall bear the fees and out-of-pocket  expenses of the one legal
      counsel selected by the Investors pursuant to Section 3(h) hereof.

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

            (a) To the extent  permitted by law, the Company will  indemnify and
      hold  harmless each Investor who holds such  Registrable  Securities,  the
      directors,  if any,  of  such  Investor,  the  officers,  if any,  of such
      Investor,  each person,  if any,  who  controls  any  Investor  within the
      meaning of the  Securities  Act or the Exchange Act, any  underwriter  (as
      defined in the Securities Act) for the Investors,  the directors,  if any,
      of such  underwriter and the officers,  if any, of such  underwriter,  and
      each person, if any, who controls any such underwriter  within the meaning
      of the Securities Act or the Exchange Act (each, an "Indemnified Person"),
      against any losses,  claims,  damages,  expenses or liabilities  (joint or
      several) (collectively "Claims") to which any of them become subject under
      the Securities Act, the Exchange Act or otherwise,  insofar as such Claims
      (or actions or proceedings,  whether  commenced or threatened,  in respect
      thereof)  arise out of or are based upon any of the following  statements,
      omissions  or   violations   in  the   Registration   Statement,   or  any
      post-effective  amendment thereof, or any prospectus included therein: (i)
      any  untrue  statement  or alleged  untrue  statement  of a material  fact
      contained in the Registration  Statement or any  post-effective  amendment
      thereof or the  omission or alleged  omission to state  therein a material




<PAGE>


Viragen, Inc./P.R.I.F., L.P. Registration Rights Agreement
December 31, 1996
Page 12

      fact  required to be stated  therein or necessary  to make the  statements
      therein  not  misleading,  (ii) any untrue  statement  or  alleged  untrue
      statement of a material fact  contained in any  preliminary  prospectus if
      used  prior  to the  effective  date of such  Registration  Statement,  or
      contained  in the final  prospectus  (as amended or  supplemented,  if the
      Company files any amendment thereof or supplement thereto with the SEC) or
      the  omission or alleged  omission  to state  therein  any  material  fact
      necessary  to  make  the  statements   made  therein,   in  light  of  the
      circumstances under which the statements therein were made, not misleading
      or  (iii)  any  violation  or  alleged  violation  by the  Company  of the
      Securities  Act, the Exchange Act or any state  securities law or any rule
      or  regulation  (the matters in the  foregoing  clauses (i) through  (iii)
      being, collectively,  "Violations"). Subject to the restrictions set forth
      in Section 6 (d) with respect to the number of legal counsel,  the Company
      shall  reimburse the Investors and each such  underwriter  or  controlling
      person,  promptly as such  expenses  are incurred and are due and payable,
      for any  legal  fees or  other  reasonable  expenses  incurred  by them in
      connection with investigating or defending any such Claim. Notwithstanding
      anything to the contrary contained herein, the  indemnification  agreement
      contained in this Section 6(a) (I) shall not apply to a Claim  arising out
      of or  based  upon a  Violation  which  occurs  in  reliance  upon  and in
      conformity  with  information  furnished  in writing to the Company by any
      Indemnified  Person or underwriter for such  Indemnified  Person expressly
      for use in connection with the preparation of the  Registration  Statement
      or any such amendment  thereof or supplement  thereto,  if such prospectus
      was timely made available by the Company  pursuant to Section 3(c) hereof;
      (II) with  respect to any  preliminary  prospectus  shall not inure to the
      benefit of any such person from whom the person  asserting  any such Claim
      purchased the  Registrable  Securities that are the subject thereof (or to
      the benefit of any person controlling such person) if the untrue statement
      or omission of material fact contained in the  preliminary  prospectus was
      corrected  in the  prospectus,  as then amended or  supplemented,  if such
      prospectus  was timely made  available by the Company  pursuant to Section
      3(c) hereof;  and (III) shall not apply to amounts paid in  settlement  of
      any Claim if such settlement is effected without the prior written consent
      of the Company,  which consent shall not be  unreasonably  withheld.  Such
      indemnity  shall  remain  in  full  force  and  effect  regardless  of any
      investigation  made by or on behalf of the  Indemnified  Persons and shall
      survive  the  transfer  of the  Registrable  Securities  by the  Investors
      pursuant to Section 9.

            (b) In  connection  with  any  Registration  Statement  in  which an
      Investor is participating, each such Investor agrees to indemnify and hold
      harmless,  to the same  extent and in the same manner set forth in Section
      6(a), the Company,  each of its directors,  each of its officers who signs




<PAGE>


Viragen, Inc./P.R.I.F., L.P. Registration Rights Agreement
December 31, 1996
Page 13

      the Registration Statement,  each person, if any, who controls the Company
      within  the  meaning  of  the  Securities  Act or the  Exchange  Act,  any
      underwriter and any other stockholder  selling securities  pursuant to the
      Registration  Statement or any of its  directors or officers or any person
      who controls such  stockholder  or  underwriter  within the meaning of the
      Securities  Act or the Exchange  Act  (collectively  and together  with an
      Indemnified  Person, an "Indemnified  Party"),  against any Claim to which
      any of them may become subject, under the Securities Act, the Exchange Act
      or  otherwise,  insofar as such  Claim  arises out of or is based upon any
      Violation,  in each case to the extent (and only to the extent)  that such
      Violation  occurs (I) in  reliance  upon and in  conformity  with  written
      information furnished to the Company by such Investor expressly for use in
      connection  with  such  Registration  Statement  or  (II)  the  Investor's
      violation  of Rules  10-b-6 or 10-b-7  under the  Exchange  Act;  and such
      Investor will promptly  reimburse any legal or other  expenses  reasonably
      incurred by them in connection  with  investigating  or defending any such
      Claim;  provided,  however, that the indemnity agreement contained in this
      Section 6(b) shall not apply to amounts paid in settlement of any Claim if
      such  settlement  is effected  without the prior  written  consent of such
      Investor,  which consent  shall not be  unreasonably  withheld;  provided,
      further,  however,  that the  Investor  shall be liable under this Section
      6(b) for only that  amount of a Claim as does not exceed the net  proceeds
      to  such  Investor  as a  result  of the  sale of  Registrable  Securities
      pursuant to such  Registration  Statement.  Such indemnity shall remain in
      full force and effect regardless of any investigation made by or on behalf
      of  such  Indemnified   Party  and  shall  survive  the  transfer  of  the
      Registrable   Securities   by  the   Investors   pursuant  to  Section  9.
      Notwithstanding   anything  to  the   contrary   contained   herein,   the
      indemnification  agreement  contained in this Section 6(b) with respect to
      any  preliminary  prospectus  shall  not  inure  to  the  benefit  of  any
      Indemnified  Party if the untrue  statement  or omission of material  fact
      contained in the preliminary prospectus was corrected on a timely basis in
      the prospectus, as then amended or supplemented.

            (c) The  Company  shall be  entitled  to  receive  indemnities  from
      underwriters,  selling  brokers,  dealer  managers and similar  securities
      industry  professionals  participating  in any  distribution,  to the same
      extent as provided  above,  with  respect to  information  such persons so
      furnished  in writing  by such  persons  expressly  for  inclusion  in the
      Registration Statement.

            (d) Promptly after receipt by an  Indemnified  Person or Indemnified
      Party  under this  Section 6 of notice of the  commencement  of any action
      (including  any  governmental   action),   such   Indemnified   Person  or
      Indemnified  Party shall, if a Claim in respect thereof is to made against
      any  indemnifying  party under this Section 6, deliver to the indemnifying

      party a written notice of the commencement  thereof and this  indemnifying
      party  shall  have the right to  participate  in,  and,  to the extent the
      indemnifying  party so desires,  jointly with any other indemnifying party
      similarly  noticed,  to assume control of the defense thereof with counsel
      mutually satisfactory to the indemnifying parties; provided, however, that
      an Indemnified  Person or Indemnified Party shall have the right to retain
      its own counsel, with the fees and expenses to be paid by the indemnifying
      party,  if,  in  the  reasonable   opinion  of  counsel  retained  by  the
      indemnifying  party, the representation by such counsel of the Indemnified
      Person  or  Indemnified   Party  and  the  indemnifying   party  would  be
      inappropriate due to actual or potential  differing interests between such
      Indemnified  Person or  Indemnified  Party and other party  represented by
      such  counsel  in such  proceeding.  The  Company  shall  pay for only one
      separate  legal  counsel for the  Investors;  such legal  counsel shall be
      selected  by  the  Investors   holding  a  majority  in  interest  of  the
      Registrable  Securities.  The  failure  to deliver  written  notice to the
      indemnifying  party within a reasonable  time of the  commencement  of any
      such action shall not relieve such indemnifying  party of any liability to
      the Indemnified  Person or Indemnified  Party under this Section 6, except
      to the extent that the indemnifying  party is prejudiced in its ability to
      defend such action. The  indemnification  required by this Section 6 shall
      be made by periodic  payments of the amount  thereof  during the course of
      the investigation or defense,  as such expense,  loss, damage or liability
      is incurred and is due and payable.

            7.  CONTRIBUTION.  To the extent any  indemnification  provided  for
      herein is prohibited or limited by law, the  indemnifying  party agrees to
      make the  maximum  contribution  with  respect to any amounts for which it
      would otherwise be liable under Section 6 to the fullest extent  permitted
      by law;  provided,  however,  that (a) no contribution shall be made under
      circumstances   where  the  maker   would   not  have  been   liable   for
      indemnification  under the fault  standards set forth in Section 6, (b) no
      seller of Registrable  Securities  guilty of fraudulent  misrepresentation
      (within  the  meaning of  Section  11(f) of the  Securities  Act) shall be
      entitled to contribution from any seller of Registrable Securities who was
      not guilty of such fraudulent  misrepresentation  and (c)  contribution by
      any seller of Registrable Securities shall be limited in amount to the net
      amount  of  proceeds  received  by  such  seller  from  the  sale  of such
      Registrable Securities.

            8. REPORTS UNDER  EXCHANGE  ACT. With a view to making  available to
      the  Investors  the  benefits  of Rule 144 or any  other  similar  rule or
      regulation  of the SEC that may at any time permit the  Investors  to sell
      securities of the Company to the public without  registration,  until such
      time as the Investors have sold all the Registrable Securities pursuant to
      a Registration Statement or Rule 144, the Company agrees to:

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

            (b) file  with the SEC in a timely  manner  all  reports  and  other
      documents  required  of the  Company  under  the  Securities  Act  and the
      Exchange Act; and

            (c)  furnish  to  each  Investor  so  long  as  such  Investor  owns
      Registrable Securities,  promptly upon request, (i) a written statement by
      the Company that it has complied with the reporting  requirements  of Rule
      144,  the  Securities  Act and the Exchange  Act,  (ii) a copy of the most
      recent  annual or quarterly  report of the Company and such other  reports
      and documents so filed by the Company and (iii) such other  information as
      may  be  reasonably  requested  to  permit  the  Investors  to  sell  such
      securities pursuant to Rule 144 without registration.

            9.  ASSIGNMENT OF THE  REGISTRATION  RIGHTS.  The rights to have the
      Company register  Registrable  Securities pursuant to this Agreement shall
      be automatically  assigned by the Investors to transferees or assignees of
      all or any portion of such  securities only if: (a) the Company is, within
      a  reasonable  time after such  transfer  or  assignment,  furnished  with
      written notice of (i) the name and address of such  transferee or assignee
      and (ii) the securities with respect to which such registration rights are
      being transferred or assigned,  (b) immediately following such transfer or
      assignment the further disposition of such securities by the transferee or
      assignee is  restricted  under the  Securities  Act and  applicable  state
      securities  laws,  and (c) at or before the time the Company  received the
      written notice  contemplated by clause (a) of this sentence the transferee
      or assignee  agrees in writing  with the Company to be bound by all of the
      provisions contained herein.

            10.  AMENDMENT  OF  REGISTRATION   RIGHTS.  Any  provision  of  this
      Agreement may be amended and the observance  thereof may be waived (either
      generally  or  in  a  particular  instance  and  either  retroactively  or
      prospectively), only with the written consent of the Company and Investors
      who  hold a  majority  in  interest  of the  Registrable  Securities.  Any
      amendment or waiver  effected in accordance  with this Section 10 shall be
      binding upon each Investor and the Company.

            11. THIRD PARTY BENEFICIARY.  The parties acknowledge and agree that
      Shoreline  Pacific,  the  Institutional  Division of Financial  West Group
      ("Shoreline  Pacific"),  shall be deemed a third party  beneficiary of the

      Company's  agreements  and  representations  set forth in this  Agreement,
      entitled  to enforce the terms  thereof,  and to  indemnification  for any
      damages  resulting  to  Shoreline  Pacific  from any actual or  threatened
      breach  thereof  by the  Company,  both in  Shoreline  Pacific's  personal
      capacity  and,  should  Shoreline  Pacific  so  elect,  on  behalf  of the
      Investor.


            12.  MISCELLANEOUS.

            (a) A person or  entity  is  deemed  to be a holder  of  Registrable
      Securities  whenever such person or entity owns of record such Registrable
      Securities. If the Company receives conflicting  instructions,  notices or
      elections  from two or more  persons or entities  with respect to the same
      Registrable   Securities,   the  Company  shall  act  upon  the  basis  of
      instructions,  notice or election  received from the  registered  owner of
      such Registrable Securities.

            (b) Notices  required or permitted to be given hereunder shall be in
      writing  and shall be  deemed to be  sufficiently  given  when  personally
      delivered  or when sent by  registered  mail,  return  receipt  requested,
      addressed (i) if to the Company, at VIRAGEN,  INC., 2343 West 76th Street,
      Hialeah, Florida, 33016, Attention:  Gerald Smith, Chairman and President,

      Investor,  at such address as such Investor shall have provided in writing
      to the Company,  or at such other address as each such party  furnishes by
      notice  given  in  accordance  with  this  Section  12(b),  and  shall  be
      effective,  when personally  delivered,  upon receipt, and when so sent by
      certified  mail,  four  business days after deposit with the United States
      Postal Service.

            (c) Failure of any party to exercise  any right or remedy under this
      Agreement or otherwise,  or delay by a party in  exercising  such right or
      remedy, shall not operate as a waiver thereof.

            (d) This Agreement  shall be enforced,  governed by and construed in
      accordance  with  the  laws of the  State  of  Florida  applicable  to the
      agreements made and to be performed  entirely  within such state,  without
      giving  effect to rules  governing the conflict of laws. In the event that
      any  provision  of this  Agreement is invalid or  unenforceable  under any
      applicable  statute or rule of law,  then such  provision  shall be deemed
      inoperative  to the extent  that it may  conflict  therewith  and shall be
      deemed modified to conform with such statute or rule of law. Any provision

AMENDED, AND THE RULES AND REGULATIONS  PROMULGATED  THEREUNDER (THE "SECURITIES
ACT").  THIS WARRANT AND THE COMMON STOCK ISSUABLE UPON EXERCISE OF THIS WARRANT

                    COMMON STOCK PURCHASE WARRANT CERTIFICATE

                             Dated: December 31,1996

                                     Warrant

                           to Purchase 375,000 Shares

                    of Common Stock, $.01 Par Value Per Share

      VIRAGEN,  INC., a Delaware  corporation (the "Company"),  hereby certifies
that P.R.I.F.,  L.P., its  permissible  transferees,  designees,  successors and
assigns  (collectively,  the  "Holder"),  for value  received,  is  entitled  to
purchase  from the Company at any time  commencing on the day following the date
that the  registration  statement for the common shares  underlying  this Common
Stock Purchase Warrant Certificate ("Warrant" or "Warrant Certificate") has been
declared  effective by the Securities and Exchange  Commission,  and terminating
June 30, 1998,  three hundred and  seventy-five  thousand  (375,000) shares (the
"Shares") of the Company's  common stock,  par value $.01 per share (the "Common
Stock"), at $6.00 per share (the "Exercise Price"); except as otherwise provided
in Section 2 hereof.

      1.  Exercise of Warrants.

      (a) Upon  presentation and surrender of this Common Stock Purchase Warrant
Certificate,  with the attached Election to Purchase form duly executed,  at the
principal  office of the  Company at 2343 West 76th  Street,  Hialeah,  Florida,
33016,  together  with a check  payable  to the  Company  in the  amount  of the
Exercise Price multiplied by the number of Shares being purchased,  the Company,
or the Company's  Transfer Agent as the case may be, shall deliver to the Holder
hereof, certificates of Common Stock which in the aggregate represent the number
of Shares being purchased.  All or less than all of the Warrants  represented by
this Warrant  Certificate  may be exercised and, in case of the exercise of less
than all, the Company,  upon surrender hereof,  will deliver to the Holder a new
Warrant  Certificate  or  Certificates  of like tenor and dated the date  hereof
entitling  said  Holder to  purchase  the number of Shares  represented  by this
Warrant  Certificate  which have not been exercised and to receive  registration
rights with respect to such Shares.

      (b) Notwithstanding any other provision of this Warrant, in no event shall
the Holder be entitled at any time to  exercise  any portion of this  Warrant in
excess of that  portion of this  Warrant  upon  exercise of which sum of (1) the
number of Common Shares  beneficially  owned by such Holder and any person whose
beneficial  ownership of Common  Shares would be  aggregated  with such Holder's
beneficial  ownership of Common  Shares for the purposes of Section 13(d) of the




<PAGE>


Common Stock Purchase Warrant Certificate
Page 2


Securities  Exchange Act of 1934,  as amended (the "1934 Act"),  and  Regulation
13D-G thereunder  (other than shares of Common Stock deemed  beneficially  owned
through the ownership of  unconverted  Series D Preferred  Shares of the Company
and  accrued  and  unpaid  dividends   thereon  and  through  the  ownership  of
unexercised Warrants) and (2) the number of Common Shares issuable upon exercise
of the portion of this Warrant with respect to which the  determination  in this
Section 1(b) is being made,  would result in beneficial  ownership by the Holder
of  more  than  4.9% of the  outstanding  Common  Shares.  For  purposes  of the
immediately  preceding  sentence,  beneficial  ownership  shall be determined in
accordance with Section 13(d) of the 1934 Act, and Regulation 13D-G  thereunder,
except  as  otherwise  provided  in  clause  (1)  of the  immediately  preceding
sentence.


      2.  Potential  Decrease  to  Exercise  Price.  In the  event  the  Company
contracts  to issue any  additional  shares of its  common  stock or  securities
convertible into,  exchangeable for, or otherwise  entitling the Holders thereof
to acquire shares of its common stock (each a "Prospective  Financing"),  within
180 days from the  closing of the  transaction  pursuant  to which this  Warrant
Certificate  was  issued  ("Closing"),   the  exercise  price  of  this  Warrant
Certificate shall be reduced as follows:

            (a) if a Prospective  Financing is contracted  for within 90 days of
      the Closing , the exercise price of the Warrants shall be $1.00 U.S.;

            (b) if a Prospective Financing is contracted for on or after 90 days
      from the Closing but before 120 days from the Closing,  the exercise price
      of the Warrants shall be $2.00 U.S.;

            (c) if a  Prospective  Financing is  contracted  for on or after 120
      days from the Closing but before 150 days from the  Closing,  the exercise
      price of the Warrants shall be $3.00 U.S.;

            (d) if a  Prospective  Financing is  contracted  for on or after 150
      days from the Closing but before 180 days from the  Closing,  the exercise
      price of the Warrants shall be $4.00 U.S.; and

            (e) if a Prospective  Financing is contracted  for on after 180 days
      from the Closing, the exercise price of the Warrants shall be $6.00 U.S.;

provided,  however,  that  the  above  provisions  will  not  apply  to  certain
Prospective  Financings as set forth in clauses (a), (b) and (c) of Section 5(i)
of the Private  Securities  Subscription  Agreement between the original parties
hereto dated December 31, 1996.

      3. Exchange and Transfer.  This Warrant  Certificate  at any time prior to
the exercise  hereof,  upon  presentation  and surrender to the Company,  may be
exchanged,  alone or with other Warrant Certificates of like tenor registered in
the name of the same Holder, for another Warrant  Certificate or Certificates of
like tenor in the name of such Holder  exercisable  for the aggregate  number of
Shares as the Warrant Certificate or Certificates surrendered.


      4.  Rights and Obligations of Holders of this Warrant Certificate.

      (a) The Holder of this Warrant Certificate shall not, by virtue hereof, be
entitled  to any rights of a  stockholder  in the  Company,  either at law or in
equity; provided, however, that in the event any certificate representing shares
of Common Stock or other securities is issued to the Holder hereof upon exercise
of some or all of the Warrants,  such Holder shall, for all purposes,  be deemed
to have  become the Holder of record of such  Common  Stock on the date on which
this Warrant  Certificate,  together with a duly executed  Election to Purchase,
was  surrendered  and  payment  of  the  aggregate   Exercise  Price  was  made,
irrespective of the date of delivery of such share certificate.

      (b) In case the Company shall (i) pay a dividend in Common Stock or make a
distribution in Common Stock, (ii) subdivide its outstanding Common Stock into a
greater number of shares,  or (iii) combine its outstanding  Common Stock into a
smaller  number of shares  (including a  recapitalization  in connection  with a
consolidation  or merger in which the  Company is the  continuing  corporation),
then (x) the Exercise Price on the record date of such division or the effective
date of such action shall be adjusted by  multiplying  such Exercise  Price by a
fraction,  the  numerator  of which is the  number of  shares  of  Common  Stock
outstanding  immediately  before such event and the  denominator of which is the
number of shares of Common Stock  outstanding  immediately  after such event and
(y) the number of shares of Common Stock for which this Warrant  Certificate may
be exercised immediately before such event shall be adjusted by multiplying such
number by a fraction,  the numerator of which is the Exercise Price  immediately
before such event and the denominator of which is the Exercise Price immediately
after such event.

      (c) In case of any  consolidation  or merger of the  Company  with or into
another corporation (other than any consolidation or merger in which the Company
is the continuing  corporation and which does not result in any reclassification
of the outstanding  shares of Common Stock or the conversion of such outstanding
shares  of  Common  Stock  into  shares or other  stock or other  securities  or
property), or the sale or transfer of the property of the Company as an entirety
or substantially as an entirety, there shall be deliverable upon exercise of the
Warrant Certificate (in lieu of the number of shares of Common Stock theretofore
deliverable)  the number of shares of stock or other  securities  or property to
which a Holder of the number of shares of Common  Stock  which  would  otherwise
have been deliverable upon the exercise of this Warrant  Certificate  would have
been entitled upon such action if this Warrant  Certificate  had been  exercised
immediately prior to such action.


<PAGE>


Common Stock Purchase Warrant Certificate

      5.  Common Stock.

      (a) The  Company  covenants  and agrees  that all  shares of Common  Stock
issuable upon exercise of this Warrant  Certificate  will,  upon delivery to the
Holder,   be  duly  and   validly   authorized   and  issued,   fully-paid   and
non-assessable.

      (b) The Company  acknowledges that it currently has an insufficient number
of authorized  shares of Common Stock  available for issuance upon conversion of
this  Warrant  Certificate.  The Company  warrants  and agrees to take all steps
reasonably  necessary  to  gain  such  approval  as may  be  required  to  issue
additional  shares of Common Stock to the Holder in accordance with the terms of
this Warrant Certificate.


      6.  Registration  Rights.  In the event the Company  files a  Registration
Statement with the Securities and Exchange  Commission for  registration  of any
shares of the Company's  Common Stock,  the Company agrees to include the number
of shares of Common Stock  represented  by this Warrant  Certificate in any such
Registration Statement.


      7.  Issuance of  Certificates.  As soon as possible  after full or partial
exercise of this Warrant  Certificate,  but in any event not more than three (3)
business days, the Company, at its expense,  will cause to be issued in the name
of and delivered to the Holder of this Warrant  Certificate,  a  certificate  or
certificates  for the number of fully paid and  non-assessable  shares of Common
Stock to which that Holder  shall be entitled on such  exercise.  No  fractional
shares  will be  issued  on  exercise  of this  Warrant  Certificate.  If on any
exercise of this Warrant Certificate a fraction of a share results,  the Company
will pay the cash value of that fractional share, calculated on the basis of the
Exercise Price.  Prior to registration of the shares of Common Stock  underlying
this Warrant Certificate, as provided in Section 5 hereof, all such certificates
shall bear a  restrictive  legend to the effect that the Shares  represented  by
such  certificate  have not been registered under the Securities Act of 1933, as
amended,  and the Shares may not be sold or  transferred  in the absence of such
registration or an exemption  therefrom,  such legend to be substantially in the
form of the bold face language appearing on Page 1 of this Warrant Certificate.


      8.  Disposition  of  Warrants  or  Shares.  The  Holder  of  this  Warrant
Certificate, each transferee hereof and any Holder and transferee of any Shares,
by his or its acceptance thereof, agrees that no public distribution of Warrants
or Shares will be made in violation of the  provisions of the  Securities Act of
1933,  as  amended,  and  the  rules  and  regulations   promulgated  thereunder
(collectively, the "Act"). Furthermore, it shall be a condition to the




<PAGE>


Common Stock Purchase Warrant Certificate
Page 5



transfer of the Warrants that any transferee  thereof deliver to the Company his
or its  written  agreement  to  accept  and be  bound  by all of the  terms  and
conditions contained in this Warrant Certificate.


            9. Notices.  Except as otherwise  specified  herein to the contrary,
all notices,  requests,  demands and other communications required or desired to
be given  hereunder  shall only be effective if given in writing by certified or
registered mail, return receipt requested,  postage prepaid, or by U. S. express
mail service or private overnight mail service (e.g. Federal Express).  Any such
notice shall be deemed to have been given (a) on the  business  day  immediately
subsequent  to  mailing,  if sent by U.  S.  express  mail  service  or  private
overnight  mail service,  or (b) three (3) business  days  following the mailing
thereof,  if mailed by certified or registered  mail,  postage  prepaid,  return
receipt requested, and all such notices shall be sent to the following addresses
(or to such other  address or addresses as a party may have advised the other in
the manner provided in this Section 9):
