ITEM 5 - OTHER EVENTS

      The  Company has  reached a series of  agreements  with the holders of its
Series  B,  Series  C,  Series  D and  Series  E  Preferred  Stock  in  order to
restructure  certain of the terms of such Preferred  Stock.  At August 15, 1997,
there  were no shares of Series B  Preferred  Stock  outstanding,  974 shares of
Series C Preferred Stock  outstanding,  8,450 shares of Series D Preferred Stock
outstanding  and 4,000  shares  of Series E  Preferred  Stock  outstanding.  The
Company had initiated  the  restructuring  in order to mitigate  concerns of the
Company and the investment  community concerning the "overhang" of the Company's
Common Stock represented by the potential conversion of these outstanding series
of  Preferred  Stock  under their  original  terms.  The primary  result of such
negotiations  was to restrict or  eliminate  the  potential  conversion  of such
Preferred Stock.

      (1.)  Effective July 1, 1997, the Company exchanged its Promissory Note in
the  principal  amount of  $9,720,240.86  for 7,445 shares of Series B Preferred
Stock.  The Note bears interest at the rate of 10% per annum,  and the principal
amount and interest is payable in nine monthly installments beginning October 1,
1997 and ending June 1, 1998. The Note is prepayable  without premium or penalty
and is non-convertible.

      (2.)  The Company has  consummated  an  agreement  with the holders of its
Series C Preferred Stock to modify  contractually  the conversion  price and the
conversion lockup  arrangements with regard to the Series C Preferred Stock. The
conversion  price of the Series C  Preferred  Stock has now been  changed to the
lower of (i) $2.20 per share and (ii) the average closing price of the Company's
Common Stock over the 5 day period ending on the day prior to the  conversion of
the Preferred Stock.

      (3.)  The Company has consummated an agreement to exchange 7,950 shares of
its newly created Series F Preferred Stock,  $1,000 face value per share, for an
equal number of shares of its previously  existing Series D Preferred Stock. The
most  significant  change  relative  to the  Series  F  Preferred  Stock  is the
limitation  imposed on the holder  that  during  any two week  period  while the
Series F  Preferred  Shares are  outstanding,  the holder  may not  request  the
conversion  into Common  Stock of any Series F Preferred  Stock  having a stated
value  greater  than  $800,000  (800  shares).  The  Series  F  Preferred  Stock
designations  also provide the Company with a cash-out  option in the event that
the  conversion  price falls below $2.00 U.S. per Common share in which case the
Company has the  right  to pay the holder cash equal to the stated  value of the
Series  F  Preferred  Stock  to  be  converted  plus  12%  of  such  amount.  In
consideration  of the holder  of  the  Series  D  Preferred  Stock  agreeing  to
this  limitation  on conversion, the Company  increased  the dividend  rate from
6% for the Series D Preferred  Stock  to 10% for the  Series F  Preferred Stock.
No other material changes were made in the substantive terms from the previously
issued Series D Preferred Stock other than certain administrative terms.

      (4.)  The Company consummated an agreement to exchange 4,000 shares of its
newly  created  Series G Preferred  Stock,  $1,000 face value per share,  for an
equal  number of shares of its  previously  existing  Series E Preferred  Stock.


                                        2


<PAGE>


Under the terms of the newly created Series G Preferred  Stock, the holder would
be restricted  from  converting such shares if the market price of the Company's
Common  Stock  is  less  than  $2.50,  subject  to  adjustment,  at the date the
conversion notice is delivered to the Company. In addition, commencing September
10, 1997  and  on  the  third business  day of  each  of  the  five  consecutive
calendar  months  thereafter commencing October 1997 through  February 1998, the
Company  will  be required to redeem  667  Shares of Series G  Preferred  Stock,
less  the  number  of Series  G  Preferred Stock converted  during the preceding
calendar month, at a redemption price  equal  to the sum of (i)  $1,000  divided
by the  applicable  conversion  percentage  and (ii) all  dividends  accrued and
unpaid  on  the  Series G Preferred  Stock at the applicable redemption date. In
consideration for these restrictions on  conversion  of the  Series G  Preferred
Stock,  the  Company  has agreed to increase  the dividend  rate from 5% for the
Series E  Preferred  Stock  to 10% for the Series G Preferred  Stock.  No  other
material  changes have been made in the substantive terms  from  the  previously
issued Series E Preferred Stock.

               Certificate of Designations, Preferences and Rights
                  of the Series F Convertible Preferred Shares
================================================================================

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


      I, Dennis W. Healey, Executive Vice President of Viragen, Inc., a Delaware
corporation (the "Corporation"), DO HEREBY CERTIFY:

      That  pursuant to authority  conferred  upon the Board of Directors by the
Certificate  of  Incorporation  of the  Corporation,  the Board of  Directors on
August 28, 1997, 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 F Convertible Preferred Shares.

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

      1.    DESIGNATION  AND  AMOUNT.   The  shares  of  such  series  shall  be
designated as the Series F Convertible Preferred Shares (the "Series F 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 F  Preferred  Shares to a number less than the number of shares
then outstanding.

      2.    DIVIDENDS  AND  DISTRIBUTIONS.  The  holders  of Series F  Preferred
Shares  shall be entitled to received a dividend of ten percent  (10%) per annum
of the stated value of the Series F Preferred  Shares,  to accrue  commencing on
the date of issuance of the Series F Preferred  Shares and payable  quarterly in
arrears, in cash,  commencing  September 30, 1997. Upon conversion,  any accrued
but unpaid dividends will be added to the stated value of the Series F Preferred
Shares converted.

      3.    VOTING RIGHTS.  Except as otherwise  provided by law, the holders of
Series F 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 F  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 F Preferred Shares unless,  prior thereto, the holders
of Series F  Preferred  Shares  shall have  received  $1,000 per share,  plus an
amount  equal  to  accrued  and  unpaid  dividends  thereon  to the date of such
payment. The Series F 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 F
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 F 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 F Preferred Shares.

      7.    CONVERSION.

            (i)   The Series F Preferred  Shares will be convertible into shares
of Common Stock, $.01 par value, of the Corporation (the "Common Shares") at the
option  of the  holder  or  holders  thereof  (the  "Holders")  at any  time  by
delivering a notice of  conversion  to the  Company.  Such  conversion  shall be
effected by  dividing  the stated  value of the Series F Preferred  Shares to be
converted by the conversion price, which shall be calculated at eighteen percent
(18%) off the  average  closing bid price of the Common  Shares,  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 and, if
the  Conversion  Price is below Two Dollars  ($2.00)  U.S. per Common Share (the
"Floor"),  the Company  shall have the right to (a) pay to the Holder cash equal
to the stated value of the Series F Preferred Shares to be converted plus twelve
percent  (12%) of such  amount  (the  "Cash-Out  Option"),  or (b)  convert  the
outstanding  Series F 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 to exercise the Cash-Out Option
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.  If the Corporation  fails to so notify the
Holder of its intent to exercise  the Cash-Out  Option  within such one business
day period,  the  Corporation  must effect the requested stock  conversion.  All
notices of conversion  and other notices given by the Holder or the  Corporation
pursuant  to  this   Certificate  may  be  given  by  telephone  line  facsimile
transmission,  shall be effective  only when  received,  and must be received by
5:00 p.m. (based on the recipient's  local time) on the applicable  business day
when such notice is due.



                                        2

            (ii)  Any Series F Preferred  Shares  remaining  outstanding  on the
second  anniversary  of the  issuance of the Series F  Preferred  Shares will be
automatically  converted  into  Common  Shares  on  such  date,  subject  to the
limitation of Section 7 (vi) hereof.  The Series F 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 F 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 F Preferred Shares being  converted,  with an
executed stock power.  The Corporation  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
F 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 F 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
conversion by delivering 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 F 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 F
Preferred Shares shall be determined as follows:






                                        3


<PAGE>



  X     $    =        Shares of Common Stock Issuable Upon
 ---   ---
  Y     x   % x CP      Conversion of Series F 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 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 F  Preferred  Shares be entitled to any time to
convert any Series F Preferred Shares (and accrued and unpaid dividends thereon)
in excess of that  number of Series F 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  F
Preferred  Shares and  accrued  and unpaid  dividends  thereon  and  through the
ownership of unexercised  warrants or other  securities  entitling the holder 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 F Preferred Shares and accrued and unpaid dividends  thereon with respect
to which the  determination in this 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 F 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 F  Preferred  Shares  shall be  required to amend,
alter, change or repeal any of the powers, designations,  preferences and rights
of the Series F Preferred Shares.

================================================================================

                                  VIRAGEN, INC.

             CERTIFICATE OF DESIGNATIONS, PREFERENCES AND RIGHTS OF
              10% CUMULATIVE CONVERTIBLE PREFERRED STOCK, SERIES G


            Viragen, Inc. (the "Company"),  a corporation organized and existing
under the General Corporation Law of the State of Delaware,  does hereby certify
that, pursuant to authority conferred upon the Board of Directors of the Company
by the Certificate of Incorporation, as amended, of the Company, and pursuant to
Section 151 of the General  Corporation Law of the State of Delaware,  the Board
of  Directors  of the  Company at a meeting  duly  called and held on August 28,
1997,  adopted  resolutions  providing  for the  designations,  preferences  and
relative,  participating,  optional  or other  rights,  and the  qualifications,
limitations  or  restrictions  thereof,  of Four Thousand  (4,000) shares of 10%
Cumulative Convertible Preferred Stock, Series G of the Company, as follows:

            RESOLVED,  that the Company is  authorized  to issue 4,000 shares of
10%  Cumulative  Convertible  Preferred  Stock,  Series G,  $1.00 par value (the
"Preferred  Shares"),  which  shall  have the  following  powers,  designations,
preferences and other special rights:

            (1)   DIVIDENDS.  The  holders  of the  Preferred  Shares  shall  be
entitled to  cumulative  dividends of ten percent  (10%) per annum of the Stated
Value (as defined below) of each Preferred  Share.  Dividends  shall accrue from
the date of  issuance  of the  Preferred  Shares  and shall be  payable  on each
October 1, January 1, April 1 and July 1 commencing  October 1, 1997, and in the
case of  conversion  of a  Preferred  Share  shall  be paid on the  date of such
conversion  through and  including  the date on which the  Preferred  Shares are
converted.  Dividends  shall be  calculated  on the  basis of a year of 360 days
consisting  of 12  30-day  months.  Dividends  shall be paid in cash or,  at the
Company's option, in fully paid and nonassessable  shares of Common Stock valued
based on the Average  Market  Price (as defined  herein) of the Common Stock for
the period of five (5) consecutive trading days ending on the trading day before
the  dividend  payment  date or the  date of  conversion,  as the  case  may be;
PROVIDED, HOWEVER, that in no event shall accrued dividends be paid in shares of
Common Stock to any holder of Preferred  Shares if, after giving  effect to such
distribution,  the number of shares of Common Stock  beneficially  owned by such
holder and all other  persons  whose  beneficial  ownership  of shares of Common
Stock would be aggregated with such holder's  beneficial  ownership of shares of
Common Stock for purposes of calculating beneficial ownership in accordance with
Sections  13(d) and 16 of the Securities  Exchange Act of 1934, as amended,  and
the  regulations  thereunder  (collectively,  "Sections 13(d) and 16")(each such
other  person a "Related  Person" of such  holder)  (other than shares of Common
Stock deemed  beneficially owned through the ownership of unconverted  Preferred
Shares)  would exceed four and  nine-tenths  percent  (4.9%) of the  outstanding




<PAGE>




shares of Common Stock and cash shall be paid in lieu of any shares which cannot
be  issued  pursuant  to  this  proviso.  For  purposes  of the  proviso  to the
immediately  preceding  sentence,  beneficial  ownership  shall be determined in
accordance with Sections 13(d) and 16, except as otherwise provided with respect
to unconverted  Preferred Shares in the  parenthetical  clause of the proviso to
the immediately preceding sentence.  Notwithstanding the foregoing,  in no event
shall  accrued  dividends  be paid in shares of Common Stock if, on the dividend
payment date, such shares of Common Stock would not be freely  tradable  because
the registration statement (the "Registration Statement") covering the shares of
Common Stock issuable hereunder and required to be filed by the Company pursuant
to the Registration  Rights Agreement,  as amended,  between the Company and the
initial holder (as assignee of all rights  thereunder)  of the Preferred  Shares
(the  "Registration  Rights  Agreement") has not been declared  effective by the
U.S.  Securities  and  Exchange  Commission  ("SEC")  (the  date  on  which  the
Registration  Statement  is  declared  effective  by the SEC  being  hereinafter
referred to as the "Effective  Date"), or if, after the Effective Date, sales of
shares of Common Stock cannot be made pursuant to the Registration  Statement by
reason  of a stop  order,  the  Company's  failure  to update  the  Registration
Statement in accordance  with the rules and regulations of the SEC or otherwise,
or if the Common  Stock is not then  listed or  included  for  quotation  on the
National  Market of the National  Association  of Securities  Dealers  Automated
Quotation  System (the  "NASDAQ-NM"),  the New York Stock Exchange (the "NYSE"),
the American  Stock  Exchange  (the  "AMEX"),  the NASDAQ  SmallCap  Market (the
"NASDAQ  SmallCap") or the NASDAQ Bulletin Board ("NASDAQ Bulletin Board").  The
Company  shall not issue any fraction of a share of Common Stock in payment of a
dividend,  but shall pay cash therefor. The Company shall, so long as any of the
Preferred  Shares  are  outstanding,  reserve  and  keep  available  out  of its
authorized and unissued  Common Stock,  such number of shares of Common Stock as
shall  from  time  to time  be  sufficient  to pay  dividends  hereunder.  Every
reference  herein  to the  Common  Stock  of the  Company  (unless  a  different
intention  is  expressed)  shall be to the  shares  of the  Common  Stock of the
Company,  $.01 par value, as such stock exists immediately after the issuance of
the Preferred Shares provided for hereunder,  or to stock into which such Common
Stock may be changed from time to time thereafter.

            "Average  Market  Price" of any  security  for any  period  shall be
computed as the  arithmetic  average of the Market  Prices for such security for
each trading day in such period.

            "Market  Price" of any  security  on any date means the  closing bid
price of such  security  on such date on the  principal  securities  exchange or
other market on which such  security is listed for trading,  as reported by such
exchange or other market  (subject to equitable  adjustment from time to time on
terms reasonably  acceptable to the holders of the outstanding  Preferred Shares
for (i) stock splits,  (ii) stock dividends,  (iii)  combinations,  (iv) capital
reorganizations,  (v)  issuance  to all  holders  of  Common  Stock of rights or
warrants to purchase  shares of Common  Stock at a price per share less than the
Market Price which would otherwise be applicable,  (vi) the  distribution by the
Company to all  holders of Common  Stock of  evidences  of  indebtedness  of the
Company or cash (other than  regular  quarterly  cash  dividends),  (vii) tender
offers by the Company or any  subsidiary of the Company or other  repurchases of


                                      2

<PAGE>




shares of Common Stock in one or more transactions which, individually or in the
aggregate,  result  in the  purchase  of  more  than  10% of  the  Common  Stock
outstanding and (viii) similar events relating to the Common Stock, in each such
case  which  occur on or after  the date of  filing  this  Certificate  with the
Secretary of State of the State of Delaware);  PROVIDED, HOWEVER, that if on any
date there shall be no reported closing bid price of such security,  the "Market
Price" on such date shall be the closing bid price of such  security on the date
next preceding such date on which a closing bid price for such security has been
so reported;  PROVIDED FURTHER,  HOWEVER,  that if on any date there shall be no
reported  closing  bid price of such  security  and at the time the  closing bid
price for such date is being determined there shall be known a closing bid price
so  reported  for the date next  subsequent  to such date on which a closing bid
price shall have been so reported,  then the Market Price on such date for which
there  shall have been no  reported  closing bid price shall be the lower of (x)
the Market Price as determined pursuant to the second proviso to this definition
and (y) the closing bid price as so reported for such succeeding day for which a
closing bid price as so reported is known.

            (2)   CONVERSION OF PREFERRED  SHARES.  The holders of the Preferred
Shares shall have the right,  at their option,  to convert the Preferred  Shares
into shares of Common Stock on the following terms and conditions:

            (a)   CONVERSION RIGHT. Each Preferred Share shall be convertible at
any time (or,  if such  Preferred  Share is called for  conversion  pursuant  to
Section 3 hereof,  at any time up to and including,  but not after, the close of
business  on the fifth  (5th) full  trading  day prior to the date fixed for the
conversion) into fully paid and nonassessable  shares (calculated to the nearest
whole share) of Common Stock,  at the conversion  price in effect at the time of
conversion   determined  as  hereinafter   provided  (the  "Conversion  Price");
PROVIDED,  HOWEVER,  that no conversions  of Preferred  Shares into Common Stock
shall be  permitted  pursuant to a Conversion  Notice (as defined  below) if the
Market  Price of the  Common  Stock is less than  $2.50  (subject  to  equitable
adjustments  from  time  to time  on  terms  acceptable  to the  holders  of the
Preferred   Shares   for   stock   splits,   stock   dividends,    combinations,
recapitalizations,  reclassifications  and similar events  occurring on or after
the date of filing of this  Certificate with the Secretary of State of the State
of Delaware) on the date such  Conversion  Notice is delivered to the Company in
accordance with Section 2(e); PROVIDED FURTHER,  HOWEVER, that in no event shall
any Restricted  Person be entitled to convert  Preferred Shares if, after giving
effect to such  conversion,  the number of shares of Common  Stock  beneficially
owned by such  Restricted  Person and all  Restricted  Persons whose  beneficial
ownership  of Common Stock would be  aggregated  with such  Restricted  Person's
beneficial  ownership  of Common Stock (other than shares of Common Stock deemed
beneficially owned through the ownership of unconverted Preferred Shares), would
exceed four and nine-tenths  percent (4.9%) of the outstanding  shares of Common
Stock (calculated in accordance with Sections 13(d) and 16). For purposes of the
proviso to the immediately  preceding  sentence,  beneficial  ownership shall be
determined  in  accordance  with  Sections  13(d) and 16,  except  as  otherwise
provided  with  respect to  unconverted  Preferred  Shares in the  parenthetical


                                      3


<PAGE>




clause  of the  second  proviso  to the  immediately  preceding  sentence.  Each
Preferred Share shall have a value of One Thousand Dollars ($1,000) (the "Stated
Value")  for the purpose of such  conversion  and the number of shares of Common
Stock issuable upon  conversion of each  Preferred  Share shall be determined by
dividing the Stated Value thereof by the Conversion Price then in effect.

            (b)   CONVERSION  PRICE. The Conversion Price shall be the lesser of
(i) an amount  equal to the Average  Market  Price for the Common  Stock for the
five (5)  consecutive  trading  days ending one trading day prior to the date of
the Conversion  Notice (as defined below)  multiplied by (A) eighty five percent
(85%),  subject  to  adjustment  as  provided  herein,  if on  the  date  of the
Conversion  Notice  shares of Common  Stock are  traded on  NASDAQ-NM  or NASDAQ
SmallCap or (B) eighty percent (80%),  subject to adjustment as provided herein,
if on the date of the Conversion Notice shares of Common Stock are traded on the
NASDAQ  Bulletin Board (the percentage then in effect is referred to hereinafter
as the "Conversion  Percentage"),  or (ii) $7.00 (the "Fixed Conversion Price"),
subject to adjustment as provided herein.

            (c)   ADJUSTMENT  TO  CONVERSION  PERCENTAGE  AND  FIXED  CONVERSION
PRICE.  If the Effective Date has not occurred within ninety (90) days after the
date of issuance of the Preferred  Shares (which period shall be extended to the
extent that any delay in the occurrence of the Effective Date is attributable to
the action or inaction of the holders or their counsel in breach of the holders'
obligations to the Company),  or if, after the Effective  Date,  sales cannot be
made pursuant to the Registration  Statement by reason of an SEC stop order, the
Company's  failure to update the  Registration  Statement in accordance with the
rules and  regulations  of the SEC or  otherwise,  or if the Common Stock is not
listed or included for quotation on the NASDAQ-NM,  NYSE, AMEX,  NASDAQ SmallCap
or NASDAQ Bulletin Board,  then, as partial relief for the damages to the holder
by  reason  of any  such  delay in or  restriction  of its  ability  to sell the
underlying  shares of Common Stock  (which  remedy shall not be exclusive of any
other remedies available at law or in equity):

            (i)   The  Conversion  Percentage  shall be  reduced  by a number of
percentage  points equal to two (2)  multiplied by the sum of: (i) the number of
periods of 30 consecutive days (prorated for periods of less than 30 consecutive
days) after the end of such 90-day period and prior to the Effective  Date; (ii)
the number of periods of 30 consecutive  days (prorated for periods of less than
30  consecutive  days ) that sales cannot be made  pursuant to the  Registration
Statement (by reason of an SEC stop order,  the Company's  failure to update the
Registration or otherwise) or Rule 144  promulgated  under the Securities Act of
1933,  as amended  (or  successor  rule or  regulation,  "Rule  144")  after the
Effective Date; and (iii) the number of periods of 30 consecutive days (prorated
for  periods of less than 30  consecutive  days)  that the  Common  Stock is not
listed or included for quotation on the NASDAQ-NM,  NYSE, AMEX,  NASDAQ SmallCap
or NASDAQ  Bulletin  Board  after  the  Effective  Date.  (For  example,  if the
Effective  Date  occurs  45  days  after  the  end of such  90-day  period,  the
Conversion Percentage would be 82% (under the circumstances set forth in Section
2(b)(i)(A))  or 77% (under  the  circumstances  set forth in Section  2(b)(i)(B)
until  any subsequent adjustment; if thereafter sales could not be made pursuant


                                      4


<PAGE>





to the Registration Statement for a period of 60 additional days, the Conversion
Percentage  would  then be 78%  (under  the  circumstances  set forth in Section
2(b)(i)(A)) or 73% (under the circumstances  set forth in Section  2(b)(i)(B))).
If a holder converts Preferred Shares into Common Stock and an adjustment to the
Conversion  Percentage is required  subsequent to such conversion,  but prior to
the sale of such Common  Stock by such  holder,  the  Company  shall pay to such
holder,  within  five (5) days  after  receipt  of a notice  of the sale of such
Common  Stock from such holder,  an amount equal to the Average  Market Price of
the Common Stock obtained upon conversion of such Preferred  Shares for the five
(5) trading  days  ending one (1)  trading  day prior to the date of  conversion
multiplied by two-hundredths (.02) times the number of periods of 30 consecutive
days  (prorated  for  periods  of less  than 30  consecutive  days) for which an
adjustment was required. Such amount may be paid at the Company's option in cash
or Common  Stock the value of which is based on the Average  Market Price of the
Common Stock for the period of five (5)  consecutive  trading days ending on the
date of the sale of such Common Stock;  PROVIDED,  HOWEVER, that any amounts due
as to that  period  during  which the  shares  are not  traded or  included  for
quotation on the NASDAQ-NM,  NYSE,  AMEX,  NASDAQ  SmallCap,  or NASDAQ Bulletin
Board shall be paid in cash only; PROVIDED,  FURTHER,  HOWEVER, that in no event
shall shares be issued  hereunder if, after giving effect to such issuance,  the
number of  shares of Common  Stock  beneficially  owned by such  holder  and all
Related  Persons  of such  holder  (other  than  shares of Common  Stock  deemed
beneficially owned through the ownership of unconverted  Preferred Shares) would
exceed four and nine tenths percent (4.9%) of the  outstanding  shares of Common
Stock;  cash shall be paid in lieu of any shares which cannot be issued pursuant
to this second  proviso.  For purposes of the second proviso to the  immediately
preceding sentence,  beneficial ownership shall be determined in accordance with
Sections 13(d) and 16, except as otherwise  provided with respect to unconverted
Preferred  Shares in the  parenthetical  clause  of the  second  proviso  to the
immediately  preceding sentence.  (For example, if the Conversion Percentage was
82% at the time of conversion of $1,000,000 in Stated Value of Preferred  Shares
(such that such  Preferred  Shares were  converted  into Common  Stock having an
Average  Market Price for the applicable  period in aggregate of  $1,219,512.10)
and  subsequent  to  conversion  there  was a  further  delay  of 60 days in the
Registration  Statement's  being declared  effective,  and such Common Stock was
sold at the end of such  60-day  period,  the  Company  would pay to the  holder
$48,780.48 in cash or Common Stock) and

            (ii)  The  Fixed  Conversion  Price as in  effect  from time to time
shall be reduced by two (2) percent  multiplied by the sum of: (i) the number of
periods of 30 consecutive days (prorated for periods of less than 30 consecutive
days) after the end of such 90-day period and prior to the Effective  Date; (ii)
the number of periods of 30 consecutive  days (prorated for periods of less than
30  consecutive  days) that sales  cannot be made  pursuant to the  Registration
Statement (by reason of an SEC stop order,  the Company's  failure to update the
Registration  or otherwise) or Rule 144 after the Effective  Date; and (iii) the
number of periods of 30  consecutive  days (prorated for periods of less than 30
consecutive  days) that the Common Stock is not listed or included for quotation



                                      5


<PAGE>




on the NASDAQ-NM, NYSE, AMEX, NASDAQ SmallCap or NASDAQ Bulletin Board after the
Effective Date. (For example, if the Effective Date occurs 45 days after the end
of such  90-day  period,  the Fixed  Conversion  Price  would be $6.79 until any
subsequent  adjustment;  if  thereafter  sales could not be made pursuant to the
Registration  Statement for a period of 60 additional days, the Fixed Conversion
Price would then be $6.52.) If a holder  converts  Preferred  Shares into Common
Stock and an adjustment to the Fixed Conversion Price is required  subsequent to
such conversion,  but prior to the sale of such Common Stock by such holder, the
Company shall pay to such holder, within five (5) days after receipt of a notice
of the sale of such Common Stock from such holder,  an amount equal to the Fixed
Conversion  Price then in effect  multiplied by  two-hundredths  (.02) times the
number of periods of 30  consecutive  days (prorated for periods of less than 30
consecutive days) for which an adjustment was required.  Such amount may be paid
at the  Company's  option in cash or Common  Stock  whose  value is based on the
Average Market Price of the Common Stock for the period of five (5)  consecutive
trading  days  ending on the date of the sale of such  Common  Stock;  PROVIDED,
HOWEVER,  that any amounts due as to that period during which the shares are not
traded or included for quotation on the NASDAQ-NM,  NYSE, AMEX,  NASDAQ SmallCap
or NASDAQ Bulletin Board shall be paid in cash only; PROVIDED, FURTHER, HOWEVER,
that in no event shall shares be issued  hereunder  if,  after giving  effect to
such issuance,  the number of shares of Common Stock  beneficially owned by such
holder and all Related  Persons of such holder would exceed four and nine tenths
percent (4.9%) of the outstanding  shares of Common Stock (than shares of Common
Stock deemed  beneficially owned through the ownership of unconverted  Preferred
Shares);  cash  shall  be paid in lieu of any  shares  which  cannot  be  issued
pursuant  to this second  proviso.  For  purposes  of the second  proviso to the
immediately  preceding  sentence,  beneficial  ownership  shall be determined in
accordance with Sections 13(d) and 16, except as otherwise provided with respect
to  unconverted  Preferred  Shares in the  parenthetical  clause  of the  second
proviso to the immediately preceding sentence.

            (d)   ADJUSTMENT TO CONVERSION  PRICE. In case the Company shall (i)
declare a  dividend  or make a  distribution  on the  outstanding  shares of its
Common  Stock in shares of its Common  Stock,  (ii)  subdivide  its  outstanding
shares of Common  Stock into a greater  number of shares,  or (iii)  combine its
outstanding  shares  of  Common  Stock  into a smaller  number  of  shares,  the
Conversion  Price in effect at the time of the record date for such  dividend or
distribution or the effective date of such  subdivision or combination  shall be
proportionately  adjusted so that the holder of any Preferred  Shares  converted
after such time shall be entitled to receive the  aggregate  number of shares of
Common Stock which the holder  would have owned or been  entitled to receive had
such Preferred  Shares been converted  immediately  prior to such record date or
effective date and the resulting Common Stock had been subject to such dividend,
distribution,   subdivision  or  combination.  Such  adjustment  shall  be  made
successively whenever any event specified above shall occur.

            (e)   CONVERSION  NOTICE.  (1)  The  right  of  the  holders  of the
Preferred Shares to convert Preferred Shares shall be exercised by delivering to
the Company a notice  stating the number of Preferred  Shares to be converted (a


                                      6


<PAGE>




"Conversion Notice"). On presentation to the Company (or at any office or agency
maintained  for the transfer of the Common  Stock) of a Conversion  Notice,  the
holder of such Preferred  Shares shall be entitled,  subject to the  limitations
herein  contained,  to receive a certificate or certificates  for fully paid and
nonassessable  shares  of  Common  Stock  in  accordance  herewith  and cash for
fractional  shares, of Common Stock on the foregoing basis. The Preferred Shares
shall be deemed to have been  converted,  and the person  converting the same to
have  become the holder of record of Common  Stock,  for all  purposes as of the
close of business on the date of delivery of the Conversion Notice.

            (2)   If  a  holder  of  Preferred  Shares  elects  to  convert  any
Preferred  Shares in  accordance  with this  Section 2, such holder shall not be
required to physically  surrender the certificate  for such Preferred  Shares to
the Company unless all of the Preferred  Shares  represented by such certificate
are being so  converted.  Each holder of Preferred  Shares and the Company shall
maintain  records  showing the number of Preferred  Shares  represented  by each
certificate for Preferred  Shares so converted and the dates of such conversions
or shall use such other method,  reasonably  satisfactory  to the holder of such
certificate  and the Company,  so as not to require  physical  surrender of such
certificate  upon  each  such  conversion.  In  the  event  of  any  dispute  or
discrepancy,  such records of the Company shall be controlling and determinative
in the absence of manifest error.  Notwithstanding the foregoing, if any portion
of the Preferred  Shares  represented by a certificate  therefor is converted as
aforesaid,  the holder of such certificate may not transfer the remaining shares
represented by such certificate  unless such holder first physically  surrenders
such certificate to the Company,  whereupon the Company will forthwith issue and
deliver  upon the order of such  holder a new  certificate,  registered  as such
holder  (upon  payment  by such  holder of any  applicable  transfer  taxes) may
request,   representing  in  the  aggregate  the  remaining   Preferred   Shares
represented  by such  certificates.  Each  holder of  Preferred  Shares  and any
assignee,  by acceptance of such  certificate,  acknowledges and agrees that, by
reason of the provisions of this paragraph, following conversion of a portion of
the Preferred Shares  represented by such  certificate,  the number of Preferred
Shares represented by such certificate may be less than the number stated on the
face  thereof  and  the  Company  may  place a  legend  to  that  effect  on the
certificates for the Preferred Shares.

            (3)   Upon  receipt by the  Company  from the Holder of a  telephone
line facsimile  transmission of a Conversion Notice meeting the requirements for
conversion as provided in Section  2(e)(1),  the Company shall issue and deliver
or  cause  to be  issued  and  delivered  to or upon  the  order  of the  holder
submitting such  Conversion  Notice  certificates  for the Common Stock issuable
upon such conversion within three business days after such receipt and otherwise
in accordance herewith and the Securities  Purchase  Agreement,  as amended (the
"Securities  Purchase  Agreement"),  applicable  to the  Company and the initial
holder of the Preferred Shares (as assignee of all rights  thereunder)  pursuant
to which the Company  issued  shares of a prior series of preferred  stock which
were  subsequently  exchanged for the Preferred  Shares  pursuant to an Exchange
Agreement (the "Exchange  Agreement") between the Company and the initial holder
of the Preferred Shares (including,  without limitation,  in accordance with the
requirement of the Securities Purchase Agreement and the Exchange Agreement that


                                        7


<PAGE>




certificates  for shares of Common Stock issued on or after the  Effective  Date
upon conversion of Preferred Shares shall not bear any restrictive legend). If a
holder of  Preferred  Shares  shall have given a  Conversion  Notice as provided
herein,  the  Company's  obligation  to issue and deliver the  certificates  for
Common Stock shall be absolute and unconditional, irrespective of the absence of
any action by the holder to enforce the same, any waiver or consent with respect
to any provision thereof, the recovery of any judgment against any person or any
action to enforce the same, any failure or delay in the enforcement of any other
obligation  of  the  Company  to  such  holder,  or  any  setoff,  counterclaim,
recoupment,  limitation or termination,  or any breach or alleged breach by such
holder  of any  obligation  to  the  Company,  and  irrespective  of  any  other
circumstance  which might  otherwise limit such obligation of the Company to the
Holder in connection  with such  conversion.  If the Company shall fail to issue
and deliver or cause to be issued and delivered the  certificates  for shares of
Common Stock upon any such conversion as and when required by the first sentence
of this Section  2(e)(3),  then,  in addition to any other  liability  which the
Company may have to the holder, the Conversion  Percentage used to calculate the
Conversion  Price  with  respect  to such  conversion  shall be  reduced  by one
percentage  point for each day after the third  trading day  following  the date
such  Conversion  Notice is  received  by the Company to the date of delivery of
such shares of Common Stock to such holder.

            (f)   MAJOR  TRANSACTIONS.  If the Company shall consolidate with or
merge into any corporation or reclassify its outstanding  shares of Common Stock
(other than by way of  subdivision  or reduction of such shares),  or in case of
any sale or transfer of all or  substantially  all of the assets of the Company,
or in the case of any share  exchange  pursuant to which all of the  outstanding
shares of Common Stock are converted into other securities or property,  (each a
"Major Transaction"), then the Company shall make appropriate provision or cause
appropriate  provision to be made so that each holder of Preferred  Shares shall
have the right thereafter to convert Preferred Shares into the kind of shares of
stock and other  securities  and property  receivable  upon such  consolidation,
merger,  sale,  transfer or share  exchange  by the persons who were  holders of
Common Stock  immediately  prior to the  effective  date of such  consolidation,
merger,  sale,  transfer or share  exchange and on a basis which  preserves  the
economic  benefits of the conversion rights of the holder of Preferred Shares on
a  basis  as  nearly  as  practical  as  such  rights   existed  prior  to  such
consolidation,  merger, sale, transfer or share exchange. If, in connection with
any such consolidation,  merger, sale, transfer or share exchange each holder of
shares of Common Stock is entitled to elect to receive either  securities,  cash
or other assets upon completion of such  transaction,  the Company shall provide
or cause to be  provided to holders of  Preferred  Shares the right to elect the
securities,   cash  or  other  assets  into  which  Preferred  Shares  shall  be
convertible  after  completion  of any such  transaction  on the same  terms and
subject  to the same  conditions  applicable  to  holders  of the  Common  Stock
(including, without limitation, notice of the right to elect, limitations on the
period in which  such  election  shall be made,  and the  effect of  failing  to
exercise the election). The Company shall not effect any such transaction unless
the provisions of this  paragraph have been complied with. The above  provisions
shall similarly apply to successive consolidations, mergers, sales, transfers or



                                      8


<PAGE>




share  exchanges.  The Company  shall give the holders of the  Preferred  Shares
written  notice of any Major  Transaction  promptly  upon the  execution  of any
agreement  whether or not binding in  connection  therewith  (including  without
limitation a letter of intent or agreement in principle) and in no event shall a
Major  Transaction  be  consummated  prior to  forty-five  (45) days  after such
notice. Such notice shall specify the action proposed to be taken by the Company
and the date as of which holders of record of the Common Stock shall participate
in any such actions or be entitled to exchange their Common Stock for securities
or other property, as the case may be.

            (g)   RESERVATION OF SHARES.  The Company  shall,  so long as any of
the  Preferred  Shares are  outstanding,  reserve and keep  available out of its
authorized  and unissued  Common Stock,  solely for the purpose of effecting the
conversion  of the  Preferred  Shares,  such number of shares of Common Stock as
shall  from time to time be  sufficient  to  effect  the  conversion  of all the
Preferred Shares then outstanding.

            (h)   FRACTIONAL SHARES. The Company shall not issue any fraction of
a share of Common Stock upon any  conversion,  but shall pay in cash therefor at
the Average Market Price then in effect multiplied by such fraction. If a holder
converts more than one Preferred  Share on the same date, any  fractional  share
otherwise  issuable upon such conversion  shall be determined by aggregating all
Preferred Shares converted by such holder on such date.

            (i)   TAXES.  The  Company  shall pay any and all taxes which may be
imposed  upon it with  respect to the issuance and delivery of Common Stock upon
conversion  of Preferred  Shares as herein  provided.  The Company  shall not be
required  in any  event to pay any  transfer  or other  taxes by  reason  of the
issuance of such Common  Stock in names other than those in which the  Preferred
Shares surrendered for conversion are registered on the Company's  records,  and
no such  conversion  or issuance of Common  Stock shall be made unless and until
the person  requesting  such  issuance has paid to the Company the amount of any
such tax, or has established to the satisfaction of the Company and its transfer
agent, if any, that such tax has been paid.

            (j)   CONVERSION  UPON  FAILURE  TO  OBTAIN  STOCKHOLDER   APPROVAL.
Notwithstanding the applicable Conversion Price pursuant to this Section (2), in
the event any holder of  Preferred  Shares is unable to convert  into  shares of
Common  Stock the full  amount of  Preferred  Shares  held by such holder at the
Conversion  Price by  reason of the  Company's  failure  to  obtain  Stockholder
Approval (as defined  herein) or a waiver thereof from the National  Association
of  Securities  Dealers,  Inc.  (the  "NASD") as required by Rule 4460(i) of the
NASD,  then the holder shall be entitled to convert any or all of its  Preferred
Shares at a  conversion  price  equal to the lesser of (i) the Fixed  Conversion
Price,  subject to  adjustment  as provided  herein and (ii) the Average  Market
Price for the Common Stock for the five (5) consecutive  trading days ending one
trading day prior to the date of the Conversion  Notice. As used in this Section
(2)(j),  "Stockholder  Approval"  means the  approval by a majority of the votes
cast by the  holders  of  shares of  Common  Stock (in  person or by proxy) at a
meeting of the  stockholders of the Company (duly convened at which a quorum was


                                      9


<PAGE>




present),  or a written consent of holders of shares of Common Stock entitled to
such number of votes given without a meeting,  of the issuance by the Company of
20% or more of the  outstanding  Common  Stock of the  Company for less than the
greater of the book or market  value of such Common Stock on  conversion  of the
Preferred Shares,  as and to the extent required under Section  4460(i)(1)(D) of
the rules of the NASD (or any successor or replacement provision thereof).

            (3)   CONVERSION AT THE COMPANY'S OPTION. So long as at the time the
Company is in compliance in all material  respects  with its  obligations  under
this Certificate,  the Registration  Rights Agreement,  the Securities  Purchase
Agreement and the Exchange Agreement, the Company may, at any time subsequent to
two hundred seventy (270) days after the Effective Date,  require the holders of
the then outstanding  Preferred Shares to convert all, but not less than all, of
such  Preferred  Shares into Common Stock by delivering  written  notice to such
holders (the "Mandatory Conversion Notice") in accordance with the terms hereof;
PROVIDED, HOWEVER, that in no event shall the Company be entitled to require any
holder to convert  its  Preferred  Shares if,  and no such  conversion  shall be
effective to the extent that, after giving effect to such conversion, the number
of shares of Common Stock issued in such  conversion and otherwise  beneficially
owned by such holder and all Related  Persons of such holder,  would exceed four
and nine-tenths  percent (4.9%) of the outstanding shares of Common Stock (other
than shares of Common Stock deemed  beneficially  owned through the ownership of
unconverted  Preferred  Shares) and that as to those Preferred  Shares which the
Company  is  prohibited  from  converting  by  operation  of this  proviso,  the
Company's  obligation to pay dividends thereon shall terminate as of the date of
the Mandatory  Conversion Notice. For purposes of the proviso to the immediately
preceding sentence,  beneficial ownership shall be determined in accordance with
Sections 13(d) and 16, except as otherwise  provided with respect to unconverted
Preferred Shares in the  parenthetical  clause of the proviso to the immediately
preceding  sentence.  The  Conversion  Price for the  purposes of this Section 3
shall be the lesser of (i) the  product  obtained  by  multiplying  the  Average
Market  Price for the Common  Stock for the five (5)  consecutive  trading  days
ending one trading day prior to the  conversion  date specified in the Mandatory
Conversion Notice by the Conversion Percentage then in effect, or (ii) the Fixed
Conversion Price then in effect. Any Mandatory  Conversion Notice shall be given
by telephone  line  facsimile  transmission  and U.S. mail to the holders of the
then  outstanding  Preferred  Shares at least fifteen (15) trading days prior to
the date fixed as the date for the  conversion  thereof at their  telephone line
facsimile  numbers and  addresses  provided to the Company for such  purpose and
shall state that the then outstanding Preferred Shares shall be converted at the
Conversion  Price in  effect  on the date  fixed  for the  conversion,  upon the
surrender,  at the time and place designated in such notice, of the certificates
therefor. Within four (4) business days after the date fixed for conversion, the
Company  shall  deliver to the holders (i) that number of shares of Common Stock
for the  Preferred  Shares  converted  as  shall  be  determined  in  accordance
herewith,  and (ii) payment of the accrued and unpaid  dividends  thereon (which
payment of dividends  may be made in shares of Common Stock in  accordance  with
Section 1 hereof if the requirements thereof are satisfied). Notwithstanding the



                                      10


<PAGE>




foregoing,  if, at the time fixed for such  conversion,  the Common  Stock to be
issued  pursuant  thereto  is  not  listed  or  included  for  quotation  on the
NASDAQ-NM,  NYSE,  AMEX,  NASDAQ  SmallCap or NASDAQ  Bulletin  Board,  then the
Mandatory Conversion Notice shall be null and void.

      (4)   MANDATORY  REDEMPTION.  (a) On each  Mandatory  Redemption  Date (as
defined  below),  the Company shall redeem from all holders of Preferred  Shares
(on a pro rata  basis  if there  shall be more  than  one  holder)  a number  of
Preferred  Shares equal to (i) 667 (or such lesser  number of  Preferred  Shares
then outstanding) LESS (ii) the number of Preferred Shares converted into Common
Stock by such  holders  during  the  calendar  month  preceding  such  Mandatory
Redemption Date. The Company's obligation to redeem Preferred Shares pursuant to
this  Section 4 may be waived in  writing by any holder at any time prior to the
Mandatory Redemption Date.

            (b)   On each  Mandatory  Redemption  Date,  the Company  shall make
payment in immediately  available funds of the applicable  Mandatory  Redemption
Price (as defined below) to such holder of Preferred Shares to be redeemed to or
upon the order of such  holder as  specified  by such  holder in  writing to the
Company at least one business day prior to such  Mandatory  Redemption  Date. If
the Company is  required to redeem all or any portion of a holder's  outstanding
Preferred  Shares  pursuant to this Section 4, the Company shall make payment to
such holder of the Preferred  Shares to be redeemed in respect of each Preferred
Share to be redeemed of an amount equal to the Mandatory  Redemption Price. Upon
redemption  of less than all of the Preferred  Shares  evidenced by a particular
certificate,  promptly,  but in no event  later than three  business  days after
surrender  of  such  certificate  to the  Company,  the  Company  shall  issue a
replacement  certificate for the Preferred  Shares evidenced by such certificate
which have not been redeemed. Only whole Preferred Shares may be redeemed.

            (c)   For purposes of this Certificate,

             "Mandatory  Redemption  Date" shall mean each of September 10, 1997
and the  third  business  day of each of the five  consecutive  calendar  months
thereafter commencing October 1997 through February 1998;

            "Mandatory   Redemption  Price"  shall  mean  the  Redemption  Price
determined  as of the last  trading day of the  immediately  preceding  calendar
month; and

            "Redemption  Price"  with  respect  to each  Preferred  Share  to be
redeemed  shall  mean an amount  equal to the sum of (A)  $1,000  divided by the
applicable  Conversion  Percentage  (expressed as a decimal  number) and (B) all
dividends accrued and unpaid thereon to the applicable redemption date.

            (5)   OPTIONAL  REDEMPTION BY THE COMPANY. So long as the Company is
in compliance in all material  respects with its  obligations  to the holders of






                                      11


<PAGE>




Preferred  Shares  (including,  without  limitation,  its obligations  under the
Exchange  Agreement,   the  Subscription  Agreement,   the  Registration  Rights
Agreement and the  provisions of this  Certificate),  the Company shall have the
right,  exercisable  on not less than 5 days or more than 20 days written notice
to the holders of record of the Preferred Shares to be redeemed,  at any time to
redeem  all,  and  from  time to  time to  redeem  any  part of the  outstanding
Preferred Shares in accordance with this Section 5. Any Notice of Redemption (as
defined  below)  under this  Section  shall be  delivered  to the holders of the
Preferred  Shares at their  addresses  appearing  on the records of the Company;
PROVIDED,  HOWEVER,  that any  failure  or defect in the giving of notice to any
such  holder  shall not affect the  validity of notice to or the  redemption  of
Preferred  Shares of any other holder.  On the redemption date and after receipt
by the Company of certificates for Preferred  Shares to be redeemed  pursuant to
this Section, the Company shall make payment of the applicable  Redemption Price
to each holder of  Preferred  Shares to be redeemed to or upon the order of such
holder as  specified  by such  holder in  writing  to the  Company  at least one
business day prior to the redemption date. If the Company exercises its right to
redeem all or a portion of the outstanding  Preferred Shares,  the Company shall
make payment to the holders of the Preferred Shares to be redeemed in respect of
each Preferred Share to be redeemed of an amount equal to the Redemption  Price.
Upon  redemption  of  less  than  all of the  Preferred  Shares  evidenced  by a
particular certificate, promptly, but in no event later than three business days
after surrender of such certificate to the Company,  the Company shall issue and
deliver to the holder of record of the surrendered certificate (or such holder's
assignee) a replacement certificate for the Preferred Shares which have not been
redeemed.  Only whole Preferred Shares may be redeemed. If the Company exercises
its  right to redeem  less  than all  outstanding  Preferred  Shares,  then such
redemption shall be made, as nearly as practical,  pro rata among the holders of
record of the  Preferred  Shares.  No  Preferred  Share as to which  the  holder
exercises  the  right  of  conversion  pursuant  to  Section  2 or the  optional
repurchase  right pursuant to Section 6 may be redeemed by the Company  pursuant
to this Section 5 on or after the date of exercise of such  conversion  right or
optional  redemption right, as the case may be, regardless of whether the Notice
of  Redemption  shall  have been  given  prior to the date of  exercise  of such
conversion right or optional redemption right, as the case may be.

            "Notice of  Redemption"  shall mean a notice given by the Company to
the holders of Preferred  Shares  pursuant to this Section 5, which notice shall
state (1) that the Company is exercising its right to redeem all or a portion of
the outstanding  Preferred  Shares pursuant to this Section 5, (2) the number of
Preferred  Shares  held  by  such  holder  which  are to be  redeemed,  (3)  the
Redemption Price per share of the Preferred Shares to be redeemed or the formula
for  determining  the  same,  determined  in  accordance  herewith  and  (4) the
applicable redemption date.

            (6)   REDEMPTION AT OPTION OF HOLDERS.  (a) Each holder of Preferred
Shares  shall be entitled,  at such  holder's  option,  by notice to the Company
given within 20 days after the occurrence of an Optional  Redemption  Event,  to
require  the  Company to redeem all or a portion of such shares (but in no event
less than ten shares,  unless such holder  holds less than ten shares,  in which


                                      12


<PAGE>




case the Company must redeem all of such holder's shares) upon the occurrence of
an Optional  Redemption Event. An "Optional  Redemption Event" means, during any
consecutive two month period, a change in a majority of either (i) the executive
officers or (ii) the members of the Board of Directors of the Company from those
persons serving in such capacities at the beginning of such period.  The Company
shall notify each holder of Preferred  Shares  within three (3) business days of
the occurrence of an Optional Redemption Event.

            (b)   To  exercise  the  optional  redemption  right,  a  holder  of
Preferred  Shares shall deliver to the Company a notice of redemption (a "Holder
Redemption Notice"),  accompanied by the certificate for the Preferred Shares to
be  redeemed.  Any  Holder  Redemption  Notice  shall  state (1) that the holder
delivering  such notice is thereby  requiring  the  Company to redeem  Preferred
Shares pursuant to this Section 6 and (2) the number of Preferred Shares held by
such holder which are to be redeemed.  In no event later than five business days
following receipt of such notice by the Company,  the Company shall make payment
in immediately  available funds of the applicable  Redemption Price with respect
to the  Preferred  Shares to be  redeemed to or upon the order of such holder as
specified by such holder in the Holder  Redemption  Notice.  Upon  redemption of
less than all of the  Preferred  Shares  evidenced by a particular  certificate,
promptly,  but in no event later than five business days after surrender of such
certificate  to the Company,  the Company shall issue a replacement  certificate
for the  Preferred  Shares  which have not been  redeemed.  Only whole shares of
Preferred Stock may be redeemed.

            (7)   VOTING  RIGHTS.  Holders  of  Preferred  Shares  shall have no
voting rights, except as required by law and by Section 10 hereof.

            (8)   LIQUIDATION,  DISSOLUTION,  WINDING  UP.  In the  event of any
voluntary or involuntary liquidation,  dissolution or winding up of the Company,
the holders of the Preferred  Shares shall be entitled to receive in cash out of
the assets of the Company,  whether from capital or from earnings  available for
distribution  to its  stockholders  (the "Preferred  Funds"),  before any amount
shall be paid to the holders of the Common Stock,  an amount equal to the Stated
Value per Preferred Share plus any accrued and unpaid dividends,  provided that,
if the  Preferred  Funds  are  insufficient  to pay the full  amount  due to the
holders of Preferred  Shares and holders of shares of other classes or series of
preferred stock of the Company that are of equal rank with the Preferred  Shares
as to payments of Preferred Funds (the "Pari Passu Shares"), then each holder of
Preferred  Shares  and Pari  Passu  Shares  shall  receive a  percentage  of the
Preferred  Funds equal to the full  amount of  Preferred  Funds  payable to such
holder as a  percentage  of the full amount of  Preferred  Funds  payable to all
holders of Preferred Shares and Pari Passu Shares. The purchase or redemption by
the Company of stock of any class,  in any manner  permitted by law,  shall not,
for the purposes hereof, be regarded as a liquidation, dissolution or winding up
of the Company. Neither the consolidation nor merger of the Company with or into
any other  corporation or corporations,  nor the sale or transfer by the Company
of less than substantially all of its assets, shall, for the purposes hereof, be
deemed to be a liquidation,  dissolution or winding up of the Company. No holder


                                      13


<PAGE>



of  Preferred  Shares  shall be entitled to receive  any  amounts  with  respect
thereto upon any  liquidation,  dissolution  or winding up of the Company  other
than the amounts provided for herein.

            (9)   PREFERRED  RANK. All shares of Common Stock shall be of junior
rank to all Preferred  Shares in respect to the preferences as to  distributions
and payments upon the liquidation, dissolution or winding up of the Company. The
rights of the shares of Common  Stock  shall be subject to the  preferences  and
relative  rights of the  Preferred  Shares.  The Company may only  authorize and
issue  additional  or other  preferred  stock  which is of junior  rank with the
Preferred Shares in respect of the preferences as to distributions  and payments
upon the  liquidation,  dissolution  or winding up of the  Company  (except  for
shares of Series F Convertible  Preferred Stock, $1.00 par value, of the Company
issued in  exchange  for its Series D  Convertible  Preferred  Stock,  $1.00 par
value,   which  may  be  of  equal  rank  in   respect  of  such   preferences).
Notwithstanding the foregoing,  the Company may issue to the original holders of
the Preferred  Shares or affiliates  thereof  preferred  stock which is of equal
rank with the Preferred Shares in respect of the preferences as to distributions
and payments upon the liquidation,  dissolution or winding up of the Company. In
the event of the merger or  consolidation  of the Company  with or into  another
corporation,   the  Preferred  Shares  shall  maintain  their  relative  powers,
designations and preferences provided for herein.

            (10)  VOTE TO CHANGE THE TERMS OF 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  Preferred
Shares  shall be required to amend,  alter,  change or repeal any of the powers,
designations, preferences and rights of the Preferred Shares.

            IN WITNESS  WHEREOF,  the Company has caused this  certificate to be
signed by Dennis W. Healey, its Executive Vice President,  as of the 28th day of
August, 1997.

            WHEREAS, on February 5, 1997 the Company issued to the Holder 15,000

            WHEREAS,  in order to  change  the  dividend  rate and the  optional

a like number of newly issued  shares of Series F Convertible  Preferred  Stock,
$1.00 par value, of the Company ("Series F Preferred Stock"); and

            WHEREAS,  the parties intend that all of their respective rights and
obligations  under  the  Subscription  Agreement  and  the  Registration  Rights
Agreement,  dated as of December  31,  1996,  between the Company and the Holder

            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 parties hereto
agree as follows:

            1.    AGREEMENT TO EXCHANGE; AMENDMENT OF SUBSCRIPTION AGREEMENT AND
REGISTRATION RIGHTS AGREEMENT.

            (A)   EXCHANGE.  The Company and the Holder hereby agree to exchange
on the  Closing  Date (as  defined  herein) a number of  shares  (the  "Series F
Preferred  Shares")  of Series F  Preferred  Stock of the  Company  equal to the
number of shares (the "Series D Preferred  Shares") of Series D Preferred  Stock
held by the  Holder on the  Closing  Date for the  number of Series D  Preferred
Shares held by the Holder on the  Closing  Date.  The Series F Preferred  Shares
shall  have the  rights,  designations  and  terms  as set  forth in the form of
Certificate  of  Designations  attached  as  ANNEX  I  to  this  Agreement  (the


                                      -1-

<PAGE>

"Certificate of  Designations").  The shares of the Company's  Common Stock, par
value $.01 per share ("Common Stock"),  issuable upon conversion of the Series F
Preferred  Shares are  referred  to herein as the  "Common  Shares."  The Common
Shares and the Series F Preferred Shares are referred to herein  collectively as

            (B)   CLOSING.  (1) The  exchange of Series F  Preferred  Shares for
Series D Preferred Shares shall occur at a closing (the "Closing") to be held on
the next business day (the "Closing  Date")  following  the  Stockholder  Notice
Period (as defined in Section 4(e)(1)) but which in no event shall be later than
August 21, 1997.  Either party may terminate  this Agreement if the Closing does
not occur on or before  August 21, 1997.  The Closing shall occur on the Closing
Date at Law Offices of Brian W Pusch, 29 West 57th Street, New York, New York.

            (2)   Each of the parties  acknowledges  that time is of the essence
in effecting  the Closing  hereunder  and shall use its best  efforts  timely to
satisfy each of the conditions to the other party's  obligations to complete the
Exchange  set forth in Section 6 or 7, as the case may be, of this  Agreement on
or before the Closing Date.

            (C)   AMENDMENT OF SUBSCRIPTION  AGREEMENT AND  REGISTRATION  RIGHTS
AGREEMENT.  Subject  to the  terms of this  Agreement  which  shall  govern  any
inconsistent  provisions,  effective  upon the Closing,  (1) the parties  hereby
amend each of the Subscription  Agreement and the Registration  Rights Agreement
such that all  references  to the Series D  Preferred  Shares  therein  shall be
deemed to be references to the Series F Preferred Shares; and (2) the respective
rights and  obligations  of the parties  with  respect to the Series D Preferred
Shares as of the date  hereof  shall  apply  with full  force and  effect to the
Series F  Preferred  Shares and the Common  Shares  issuable  pursuant  thereto.
Except as amended  hereby or as  otherwise  provided  herein,  the  Subscription

and the Registration Rights Agreement shall continue in full force and effect.

            2.    HOLDER REPRESENTATIONS, WARRANTIES, ETC.

            The Holder  represents  and  warrants to, and  covenants  and agrees
with, the Company as follows:

            (A)   INVESTMENT  PURPOSE.  The  Holder is  acquiring  the  Series F
Preferred  Shares for its own  account for  investment  only and not with a view
towards the public sale or distribution thereof.

            (B)   ACCREDITED INVESTOR. The Holder is an "accredited investor" as
that term is defined in Rule 501 of the General Rules and Regulations  under the

            (C)   REOFFERS AND RESALES.  All subsequent  offers and sales of the
Shares by the Holder shall be made pursuant to  registration of the Shares being
offered  and  sold  under  the  1933  Act  or  pursuant  to  an  exemption  from
registration.

            (D)   EXCHANGE  AGREEMENT.  This Agreement has been duly and validly
authorized,  executed  and  delivered on behalf of the Holder and is a valid and
binding  agreement  of the  Holder  enforceable  in  accordance  with its terms,
subject as to enforceability to general  principles of equity and to bankruptcy,

creditors' rights generally.

            3.    COMPANY REPRESENTATIONS, WARRANTIES, ETC.

            The Company  represents  and warrants to, and  covenants  and agrees
with, the Holder that:

            (A)   CONCERNING  THE SHARES.  The Shares have been duly  authorized
and the Series F Preferred  Shares,  when  issued in  exchange  for the Series D
Preferred Shares in accordance with this Agreement,  and the Common Shares, when
issued  upon  conversion  of the  Series F  Preferred  Shares,  will be duly and
validly issued,  fully paid and  non-assessable  and will not subject the holder
thereof  to  personal  liability  by reason of being such  holder.  There are no
preemptive rights of any stockholder of the Company,  as such, to acquire any of
the Shares. The Common Stock is listed for trading on the Nasdaq National Market
("Nasdaq")  and (1) the  Company  and the  Common  Stock meet the  criteria  for
continued  listing and trading on Nasdaq;  (2) the Company has not been notified
since January 1, 1997 by the National  Association of Securities  Dealers,  Inc.
(the  "NASD") of any  failure or  potential  failure  to meet the  criteria  for
continued  listing and trading on Nasdaq and (3) no suspension of trading in the
Common Stock is in effect. The Common Shares are listed for trading on Nasdaq.

            (B)   EXCHANGE  AGREEMENT.  This Agreement has been duly and validly
authorized,  executed  and  delivered  by the Company and is a valid and binding
agreement of the Company enforceable in accordance with its terms, subject as to
enforceability  to general  principles of equity and to bankruptcy,  insolvency,
moratorium and other similar laws affecting the enforcement of creditors' rights
generally.

            (C)   NON-CONTRAVENTION.   The   execution   and  delivery  of  this
Agreement by the Company and the  consummation by the Company of the issuance of
the Series F Preferred  Shares and the other  transactions  contemplated by this
Agreement,  and the terms of the  Series F  Preferred  Stock do not and will not
conflict  with or  result  in a breach  by the  Company  of any of the  terms or
provisions of, or constitute a default under,  the certificate of  incorporation
or by-laws of the Company,  or any indenture,  mortgage,  deed of trust or other








                                      -3-

material  agreement or instrument to which the Company is a party or by which it

regulation  or any  applicable  decree,  judgment or order of any court,  United
States  federal  or  state  regulatory  body,  administrative  agency  or  other
governmental body having  jurisdiction over the Company or any of its properties

the State of Delaware.

of the Company to the Holder in connection with the transactions contemplated by
this Agreement, including, without limitation, all reports and other information
filed with the SEC since January 1, 1996 (the "SEC  Reports"),  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
circumstances under which they are made, not misleading.

            (G)   ABSENCE OF CERTAIN CHANGES. Since December 31, 1996, there has
been no material  adverse  change and no  material  adverse  development  in the
business,  properties,  operations,  condition (financial or other),  results of

            (J)   REGISTRATION  STATEMENT.  Registration Statement (Registration
No.  333-23061) (as amended to date, the "Registration  Statement")  registering
the resale of the shares of Common Stock issuable upon  conversion of the Series

similar  proceeding  relating  to  the  Registration  Statement  is  pending  or
threatened.

            4.    CERTAIN COVENANTS AND ACKNOWLEDGMENTS.

            (A)   TRANSFER RESTRICTIONS.  The Holder and the Company acknowledge
and agree that (1) the Series F Preferred Shares have not been and are not being
registered  under  the  provisions  of the 1933  Act and may not be  transferred
unless (A)  subsequently  registered  thereunder  or (B) the  Holder  shall have
delivered to the Company an opinion of counsel, reasonably satisfactory in form,
scope and  substance to the  Company,  to the effect that the Series F Preferred
Shares  to be sold or  transferred  may be sold or  transferred  pursuant  to an
exemption from such registration;  (2) any sale of the Series F Preferred Shares
made in reliance on Rule 144 promulgated  under the 1933 Act may be made only in
accordance  with  the  terms  of said  Rule  and  further,  if said  Rule is not
applicable,  any such resale of Series F Preferred Shares under circumstances in
which the seller,  or the person through whom the sale is made, may be deemed to
be an underwriter,  as that term is used in the 1933 Act, may require compliance
wit some other  exemption under the 1933 Act or the rules and regulations of the
SEC  thereunder;  (3)  neither  the  Company  nor any other  person is under any
obligation  to register  the Series F Preferred  Shares under the 1933 Act or to
comply with the terms and  conditions  of any exemption  thereunder  (other than
pursuant to Section 4(c) hereof),  with respect to the sale or other transfer of
the Series F Preferred  Shares;  and (4) the Company shall agree in writing with
any  transferee  of the  Series F  Preferred  Share  that the  Company  and such
transferee  shall  be  bound  by and  entitled  to  the  respective  rights  and
obligations of the Company and the Holder as set forth in this Section 4.

            (B)   RESTRICTIVE  LEGEND.  The Holder  acknowledges and agrees that
the certificates for the Series F Preferred Shares may bear a restrictive legend
in  substantially  the following form (and a  stop-transfer  order may be placed
against transfer of the certificates for the Series F Preferred Shares):

      THE  SECURITIES  EVIDENCED BY THIS  CERTIFICATE  HAVE NOT BEEN  REGISTERED
      UNDER THE  SECURITIES  ACT OF 1933,  AS AMENDED (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






                                      -5-

<PAGE>

      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, AS AMENDED BY THE
      EXCHANGE  AGREEMENT  BETWEEN THE COMPANY AND P.R.I.F.,  L.P.,  DATED AS OF
      JULY 23, 1997. A COPY OF THE AFORESAID SUBSCRIPTION AGREEMENT AND EXCHANGE
      AGREEMENT MAY BE OBTAINED FROM THE COMPANY'S EXECUTIVE OFFICES.

            Upon conversion of the Series F Preferred Shares into Common Shares,
the Company shall issue a Common Stock  certificate or certificates  without any
restrictive legend to the holder of such shares. Such Common Shares shall not be
subject to any stop transfer  instructions  and shall be freely  transferable on
the books and records of the Company.

            (C)   REPORTING STATUS. So long as the Holder  beneficially owns any
of the Series F Preferred  Shares or the Common  Shares,  the Company shall file
all reports required to be filed with the SEC pursuant to Section 13 or 15(d) of
the 1934 Act and the  Company  shall  not  terminate  its  status  as an  issuer
required  to file  reports  under the 1934 Act even if the 1934 Act or the rules
and regulations thereunder would permit such termination.

            (D)   RESTRICTION ON CONVERSIONS. Effective on the Closing Date, the
Holder  hereby  agrees that during  each two (2) week period  commencing  on the
Closing Date,  and  continuing for as long as the Holder shall hold any Series F
Preferred  Shares,  the Holder may not request the conversion into Common Shares
of Series F Preferred Shares having a stated value (including accrued and unpaid
dividends  for which  conversion  into Common Shares is requested by the Holder)
greater than $800,000;  PROVIDED,  HOWEVER, that the foregoing restriction shall
apply only so long as the  Company  is in  compliance  with all of its  material
obligations to the Holder under this Agreement, the Certificate of Designations,
the Subscription Agreement and the Registration Rights Agreement.

            (E)   NASD MATTERS.  (1) The Company  represents and warrants to the
Holder that (A) it has received the NASD's  concurrence  ("NASD  Approval") with
the Company's position that the approval by the Company's  stockholders given at
a Special Meeting of the  Stockholders  held on June 27, 1997 of the issuance of
the  Series D  Preferred  Shares  shall be deemed  shareholder  approval  of the
issuance of the Series F Preferred Shares for purposes of Rule 4460(i)(1)(D)(ii)
(the "Rule") of the Nasdaq National Market Issuer Designation  Requirements such
that the  issuance of Common  Shares upon  conversion  of the Series F Preferred
Shares  would not be  subject  to any  restrictions  under the Rule and (B) as a
condition  of such NASD  Approval,  the NASD has  required the Company to mail a
notice to all stockholders (the "Notice") advising them of the Exchange ten days
prior to the  Closing  Date  (such ten day period is  referred  to herein as the






                                      -6-

<PAGE>


"Stockholder  Notice  Period") and to file a Current Report on Form 8-K with the
SEC reporting the Exchange.  The Company agrees to promptly  prepare the Notice,
obtain the NASD's prior approval  thereof (if so required),  and mail the Notice
to its stockholders.

            (2)   If,  notwithstanding the NASD Approval, at any time the Holder
is unable to receive on a timely  basis  Common  Shares upon  submission  to the
Company of a notice of conversion of the Series F Preferred  Shares by reason of
the Rule or the provisions of Section 4(v) of the Subscription Agreement, within
five days of receipt of a written  request  from the Holder,  the Company  shall
redeem such inconvertible Series F Preferred Shares (the "Inconvertible Shares")
by paying the Holder for each such  Inconvertible  Share a cash amount  equal to
(A) the sum of (1)  $1,000  and (2) an amount  equal to the  accrued  but unpaid
dividends on such Inconvertible Shares through the payment date TIMES (B) 118%.

            (F)   FAILURE TO REDEEM.  If at any time the Company shall  exercise
its  Cash-Out  Option  (as  defined  in  Section  7(i)  of  the  Certificate  of
Designations)  with  respect to a  requested  conversion  of Series F  Preferred
Shares  and  thereafter  fail to make the  required  cash  payment to the Holder
within  ten  business  days  after  receipt  by the  Company  of the  notice  of
conversion  (the "Notice Date") with respect to such Series F Preferred  Shares,
the  Company  shall  compensate  the Holder  for such late  paymen by paying the

conflict  with or  result  in a breach  by the  Company  of any of the  terms or
provisions of, or constitute a default under,  the certificate of  incorporation
or by-laws of the Company,  or any indenture,  mortgage,  deed of trust or other

      SUBSTANCE AND SCOPE REASONABLY ACCEPTABLE TO THE COMPANY THAT REGISTRATION
      IS NOT  REQUIRED  UNDER THE ACT OR UNLESS SOLD  PURSUANT TO RULE 144 UNDER
      THE ACT.  ANY SUCH SALE,  ASSIGNMENT  OR  TRANSFER  MUST ALSO  COMPLY WITH

restrictive legend to the holder of such shares. Such Common Shares shall not be
subject to any stop transfer  instructions  and shall be freely  transferable on
the books and records of the Company.

            (2) The  certificates  for the Series G Preferred  Shares shall bear
the following additional legends:

      SECTION 2(e)(2) OF THE CERTIFICATE OF DESIGNATIONS, PREFERENCES AND RIGHTS
      OF THE 10% CUMULATIVE  CONVERTIBLE  PREFERRED STOCK, SERIES G, PURSUANT TO
      WHICH THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ISSUED PERMITS A
      HOLDER OF THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE TO CONVERT SUCH
      SECURITIES IN ACCORDANCE  WITH THE  CERTIFICATE  OF  DESIGNATIONS  WITHOUT
      BEING REQUIRED TO PHYSICALLY SURRENDER THIS CERTIFICATE TO THE CORPORATION
      UNLESS  ALL  OF  THE  SECURITIES  REPRESENTED  HEREBY  ARE  SO  CONVERTED.
      CONSEQUENTLY, FOLLOWING CONVERSION OF ANY OF THE SECURITIES REPRESENTED BY

      THE  CORPORATION  WILL FURNISH  WITHOUT CHARGE TO EACH  STOCKHOLDER WHO SO
      REQUESTS,  A  STATEMENT  OF  THE  POWERS,  DESIGNATIONS,  PREFERENCES  AND

of the Series G Preferred  Shares or the Common  Shares,  the Company shall file
all reports required to be filed with the SEC pursuant to Section 13 or 15(d) of
the 1934 Act and the  Company  shall  not  terminate  its  status  as an  issuer
required  to file  reports  under the 1934 Act even if the 1934 Act or the rules
and regulations thereunder would permit such termination.

            (D)   NASD MATTERS.  (1) The Company  represents and warrants to the
Holder that (A) it has received the NASD's concurrence ("NASD Approval"), a copy
of which is attached  hereto as EXHIBIT 4(D),  with the Company's  position that
the approval by the  Company's  stockholders  given at a Special  Meeting of the
Stockholders  held on June 27,  1997 of the  issuance  of the Series E Preferred
Stock  shall be deemed  shareholder  approval  of the  issuance  of the Series G

Preferred  Stock for  purposes  of Rule  4460(i)(1)(D)(ii)  (the  "Rule") of the
Nasdaq National Market Issuer Designation Requirements such that the issuance of
Common  Shares  upon  conversion  of the Series G  Preferred  Stock would not be
subject to any  restrictions  under the Rule and (B) as a condition of such NASD
Approval, the NASD has required the Company to mail a notice to all stockholders
(the "Notice")  advising them of the Exchange ten days prior to the Closing Date
(such ten day period is referred to herein as the "Stockholder  Notice Period ).
The Company  agrees to promptly  prepare  the  Notice,  obtain the NASD's  prior
approval thereof,  mail the Notice to its stockholders and file a Current Report
on Form 8-K with the SEC reporting the Exchange.

            (2)   If,  notwithstanding the NASD Approval, at any time the Holder
is unable to receive on a timely  basis  Common  Shares upon  submission  to the
Company of a notice of conversion of the Series G Preferred  Shares by reason of
the Rule or the  provisions  of  Section  4(i)(ii)  of the  Securities  Purchase
Agreement,  the  Company  shall be  entitled  to convert  its Series G Preferred
Shares in accordance with Section 2(j) of the  Certificate of  Designations  and
shall be entitled to receive  liquidated damages pursuant to Section 4(i) of the
Securities Purchase Agreement.

            (E)   AMENDED PROSPECTUS.  At least three business days prior to the
Closing Date, the Company shall provide to the Holder and its counsel for review
a draft amended prospectus,  forming part of the Registration  Statement,  to be
filed by the Company on or before the  Closing  Date with the SEC  covering  the
resale of the Common Shares under the 1933 Act.

            (F)   PAYMENT OF  DIVIDENDS  ON SERIES E  PREFERRED  STOCK.  For the
period  commencing  July 18, 1997 to and including the date prior to the Closing
Date,  the  Company  agrees to pay the Holder  dividends  on its 4,000  Series E
Preferred  Shares at the rate of ten percent (10%) per annum of the stated value
of the Series E Preferred  Stock as if such 10% rate were set forth in Section 1
of the  Certificate  of  Designations,  Preferences  and  Rights of the Series E
Preferred  Stock.  Prior to the Closing Date the Company shall pay to the Holder
in cash an amount  equal to all  accrued  and unpaid  dividends  on the Series E
Preferred Stock payable to and including the date prior to the Closing Date.

            (G)   EXPENSES.  Whether or not the Closing occurs, the Company will
pay or reimburse up to $7,000 of the out-of-pocket expenses (including,  without
limitation,  legal fees and expenses)  incurred by the Holder in connection with
this Agreement and the transactions contemplated hereby.

            5.    TRANSFER AGENT INSTRUCTIONS; CONVERSION PROCEDURE.

              On or prior to the  Closing  Date,  the Company  will  irrevocably
instruct (the "Transfer Agent  Instructions")  its transfer agent for the Common
Stock,  ChaseMellon Shareholder Services L.L.C. (the "Transfer Agent"), to issue
certificates  for Common  Shares from time to time upon  conversion  of Series G

stop-transfer instructions to give effect to Section 4(a) hereof with respect to
the Series G Preferred Shares will be given by the Company to the Transfer Agent
and that the Common Shares shall  otherwise be freely  transferable on the books

                                SCHEDULE 3(H)

            The Company is named as a defendant in KENNETH WELT, AS TRUSTEE, VS.
HOWARD APPEL, ET AL. Case No. 94-14243-BKC-AJC, ADV. No. 97-0473-BKC-AJC-A. This
is an  action  filed by a  bankruptcy  trustee  against  the  Company  and other
defendants seeking a return of alleged  preferential  transfers.  This matter is
preliminarily  set for trial in November,  1997.  Discovery is proceeding.  This
action  relates to alleged  preferential  transfers  made to Sector & Associates
Ltd., now Viragen (Europe)  Limited,  prior to the Company's  acquisition of the
latter.  The  Company  denies  that  preferential  transfers  were made and will
vigorously  defend  the  claims.  In any event,  to the extent any  preferential
transfers  were  involved,  they would pertain to the  Company's  majority-owned
subsidiary, Viragen (Europe) Limited, and not the Company.

            The Company  and its  management  have  received  from  stockholders
various allegations of improper conduct and breach of fiduciary responsibilities
in connection  with the issuance of various  series of its  Preferred  Stock and
associated  dilution.  In the event of any litigation by its  stockholders,  the
Company would vigorously defend such claims.
