             "participant" in Schedule 14A of the Securities
             Exchange  Act, as such Schedule is currently in
             effect   (for   purposes   of  which  the  term
             "registrant"  shall mean the  Company),  to the
             extent the subject  solicitation  of proxies or
             consents is in connection  with the election or
             removal of directors  of the  Company,  and any
             Affiliate or Associate of any such Person.

        (c) Section  5.1 of the  Agreement  is hereby  amended by adding to such
Section a new Subsection (c) as follows:

                (c)  Notwithstanding the other provisions of
             this  Section 5.1, in the event that a majority
             of the Board of  Directors  of the  Company  is
             comprised  of  Persons  (or  their   respective
             successors)  elected at a meeting or by written
             consent of  shareholders  who are not nominated
             by the Board of Directors in office immediately
             prior to such  meeting  or  action  by  written
             consent  and who were  elected  to the Board of
             Directors    for   the    purpose   of   either
             facilitating   a   Transaction   with  a  Proxy
             Contestant   or   circumventing   directly   or
             indirectly the  provisions of this  subsection,
             then (i) the Rights may not be  redeemed  for a
             period of 365 days following the  effectiveness
             of  such   election  if  such   redemption   is
             reasonably likely to have the purpose or effect
             of facilitating such a Transaction with a Proxy
             Contestant  and  (ii)  the  Rights  may  not be
             redeemed  following such 365 day period if such
             redemption  is  reasonably  likely  to have the
             purpose of facilitating such Transaction with a
             Proxy   Contestant  and  during  such  365  day
             period, the Company entered into any agreement,
             arrangement  or  understanding   with  a  Proxy
             Contestant  which is reasonably  likely to have
             the  purpose  or  effect of  facilitating  such
             Transaction with a Proxy Contestant.

        (d) Section 5.4 of the  Agreement is hereby  amended by inserting at the
end thereof the following:

             Notwithstanding   anything  contained  in  this
             Agreement to the contrary,  in the event that a
             majority  of  the  Board  of  Directors  of the
             Company  is  comprised  of  Persons  (or  their
             respective  successors) elected at a meeting or
             by written consent of shareholders  who are not
             nominated  by the Board of  Directors in office
             immediately  prior to such meeting or action by
             written  consent  and who were  elected  to the
             Board of  Directors  for the  purpose of either
             facilitating   a   Transaction   with  a  Proxy
             Contestant   or   circumventing   directly   or
             indirectly the provisions of this

473363.1





             sentence or Section 5.1(c) hereof, then (i) for
             a   period   of   365   days    following   the
             effectiveness  of such action,  this  Agreement
             shall not be  amended or  supplemented,  and no
             approval   may  be  granted  by  the  Board  of
             Directors  under clause (iii) of the definition
             of "Acquiring  Person" contained in Section 1.1
             hereof, in any manner reasonably likely to have
             the  purpose  or  effect  of   facilitating   a
             Transaction with a Proxy Contestant and (ii) no
             such  amendments,  supplements or approvals may
             be made  following  such 365 day  period if (x)
             such  amendment,   supplement  or  approval  is
             reasonably likely to have the purpose or effect
             of  facilitating  a  Transaction  with a  Proxy
             Contestant  and (y) during such 365 day period,
             the   Company   enters   into  any   agreement,
             arrangement  or  understanding  with such Proxy
             Contestant  which is reasonably  likely to have
             the  purpose or effect of  facilitating  such a
             Transaction with such Proxy Contestant.

        4.  Counterparts.  This  Amendment  may be  executed  in any one or more
counterparts,  each of which shall be deemed an original  and all of which shall

                                    EXHIBIT A

                             ISOLYSER COMPANY, INC.
                  SUMMARY OF SHAREHOLDER PROTECTION RIGHTS PLAN
                    AS AMENDED BY THE FIRST AMENDMENT THERETO


DISTRIBUTION AND TRANSFER OF RIGHTS; RIGHTS CERTIFICATES: The Board has declared
a dividend of one Right for each share of Common Stock  outstanding  on December
31, 1996.  Prior to the  Separation  Time referred to below,  the Rights will be
evidenced by and trade with the Common Stock and will not be exercisable.  After
the Separation  Time, the Company will mail Rights  Certificates to shareholders
and the Rights will become transferable apart from the Common Stock.

SEPARATION  TIME:  Rights  will  separate  from  the  Common  Stock  and  become
exercisable  following  the  earlier  of (i)  the  date of the  Flip-in  Trigger
referred to below or (ii) the tenth business day (or such later day as the Board
may decide) after any person  commences a tender offer that would result in such
person holding a total of 15% or more of the Common Stock.

EXERCISE  OF RIGHTS:  After the  Separation  Time,  each Right will  entitle the
holder to purchase,  for an Exercise  Price of $60.00,  Participating  Preferred
Stock  designed to have  economic and voting terms similar to those of one share
of Common Stock.

"FLIP-IN" TRIGGER: Upon announcement that any person has acquired 15% or more of
the outstanding Common Stock, then:

(i)  Rights owned by the person acquiring such stock (an "Acquiring  Person") or
     transferees  thereof will  automatically  become void;  and

(ii) each other Right will automatically become a right to buy, for the Exercise
     Price,  that number of shares of Common  Stock or  Participating  Preferred
     Stock having a market value of twice the Exercise Price.

EXCHANGE  OPTION:  If any person acquires between 15% and 50% of the outstanding
Common Stock, the Board may, in lieu of allowing Rights to be exercised, require
each  outstanding  Right  to be  exchanged  for one  share  of  Common  Stock or
Participating Preferred Stock designed to have economic and voting terms similar
to those of one share of Common Stock.

"FLIP-OVER" TRIGGER:  After an Acquiring Person has become such, the Company may
not  consolidate  or merge  with,  or sell 50% or more of its  assets or earning
power to, any person (a "Flip-Over Transaction or Event") if at the time of such
merger or sale (or agreement to do any of the  foregoing)  the Acquiring  Person
controls  the Board of  Directors  and,  in the case of a merger,  will  receive
different  treatment than all other shareholders unless proper provision is made
so that each Right  would  thereafter  become a right to buy,  for the  Exercise
Price,  that  number of shares of common  stock of such  other  person  having a
market value of twice the Exercise Price.

REDEMPTION:  The  Rights may be  redeemed  by the  Board,  at any time,  until a
"Flip-in"  Trigger  has  occurred,  at a  Redemption  Price of $0.001 per Right,
subject to the restriction described below.

473363.1





POWER TO AMEND:  The Board may amend the Plan in any  respect  until a "Flip-in"
Trigger has occurred,  subject to the restriction  described below.  Thereafter,
the Board may amend the Plan in any  respect  not  materially  adverse to Rights
holders generally.

RESTRICTION ON REDEMPTION AND  AMENDMENTS:  The right of the Board to redeem the
rights or amend the Plan is  restricted  in the event of  certain  circumstances
designed to address a situation where a potential  "raider" has obtained control
of the Board through the election or  appointment  of  non-incumbent  directors.
These restrictions  generally prohibit redemptions or amendments  facilitating a
transaction with an Acquiring Person for one year or longer following  obtaining
control of the Board.

EXPIRATION:  The  Rights  will  expire no later  than ten years from the date of
their issuance.
