Migo,

         The following is the substance of our telephone discussion last week.

         As you  suggested I am stating  it, in my own words,  as an addendum to
the agreement  Terence and I worked out. To give you the complete file I am also
including copies of the original proposal I drafted and the "official"  document
we signed.

         The  agreement  Terence and I executed,  May 27, 1998,  is by this memo
amended as follows:

              1.   Section one.  "EMPLOYMENT" paragraph (a) is amended to read:

                           "In accordance with that certain Employment Agreement
                  (the  "Existing  Agreement")  dated  January 3, 1994,  between
                  Microtek Medical, Inc. ("Microtek"), a wholly owned subsidiary
                  of Isolyser, and Employee, as amended, Employee is employed by
                  Microtek and also currently serves as Executive Vice President
                  of Isolyser.  Subject to and in  accordance  with the terms of
                  the Existing Agreement, the Existing Agreement shall remain in
                  effect and employee  shall continue to serve as Executive Vice
                  President of Isolyser until December 31, 1999."

              2.  The contract will end December 31, 2003.

              3.  All other  provisions  of the  contract  remain as stated in
                  the original agreement.

              4.  This  memo  signed by Migo  Nalbantyan  and  Lester  J.  Berry
                  constitutes  an amendment to the original  contract  dated May

         Please sign both copies and return one for my file.

                              EMPLOYMENT AGREEMENT


         THIS AGREEMENT is made and entered into as of the ____ day of ________,
1998, but effective as of December 31, 1998 (the "Effective  Date"), by ISOLYSER
COMPANY,  INC.,  a Georgia  corporation  ("Isolyser"),  and LESTER J.  BERRY,  a
Mississippi resident ("Employee").

         In consideration  of the mutual covenants  contained in this Agreement,
Isolyser and Employee agree as follows:

         1.       Employment.

                  (a) In accordance with that certain Employment  Agreement (the
"Existing  Agreement")  dated January 3, 1994,  between Microtek  Medical,  Inc.
("Microtek"),  a wholly-owned  subsidiary of Isolyser, and Employee, as amended,
Employee is employed by Microtek and also  currently  serves as  Executive  Vice
President  of  Isolyser.  Subject  to and in  accordance  with the  terms of the
Existing  Agreement,  the Existing Agreement shall remain in effect and Employee
shall  continue to serve as Executive  Vice President of Isolyser until December
31, 1998.

                  (b) Effective on the Effective Date,  Employee shall no longer
serve as Executive Vice President of Isolyser and the Existing  Agreement  shall
terminate. Employee shall, however, continue to serve as an employee of Isolyser
through  December 31, 2003 in the  non-executive  capacity of Vice President for
Special  Projects.  In such capacity,  he shall assist  Isolyser  faithfully and
diligently  to achieve  its  objectives  from time to time as may be  reasonably
requested by the President of Isolyser,  and shall take no action which would be
contrary to such objectives. Employee shall not be required to perform duties at
variance to duties  normally  assigned to senior  executive  level  personnel of
Isolyser. As such Vice President, Employee shall have no policy making authority
on behalf of  Isolyser  and shall  have no  authority  to bind  Isolyser  to any
obligations.  Employee shall not be required to devote his full working time and
attention to the business of Isolyser, and may be engaged in other activities to
which he shall be entitled to devote a substantial  portion of his time, subject
to paragraph 3 of this Agreement.  Absent mutual agreement to the contrary,  the
maximum  number of days  Employee  shall be required  to serve in such  capacity
shall be fifteen working days per year.

         2.  Compensation  and Benefits.  As full  compensation for all services
rendered by Employee  pursuant to this Agreement and as full  consideration  for
all terms of this  Agreement,  beginning as of the Effective Date and thereafter
until December 31, 2003, Employee shall be entitled to the following:

                  (a) Subject to Section 7(a)  hereof,  a base salary of $13,000
per year through and including  December 31, 2003 payable so long as Employee is
not in breach of this Agreement following five days notice of any such breach by
Isolyser to Employee.  Such salary shall be paid in installments consistent with
the normal practices of Isolyser, but not less frequently than monthly.

                  (b) Subject to Section 7(a) hereof, Employee hereby elects not
to participate in and agrees that he shall not be entitled to participate in any
and all employee benefit plans,  medical  insurance plans, life insurance plans,
disability  income plans,  retirement plans and other benefit plans (except that
Employee  shall remain  eligible to  participate  in the  Company's  401(k) plan
subject to the terms of the applicable  plan  documents and legal  requirements)
from  time to time in  effect  for  senior  executives  or  other  employees  of
Isolyser.  In lieu of participation  in any and all such plans,  Isolyser agrees
(x) that the Split  Dollar Life  Insurance  Agreement  dated as of May 25, 1994,
between  Microtek  and  Employee  shall  remain  in full  force  and  effect  in
accordance  with its terms,  and (y) to  continue  to provide  health  insurance
benefits  (after payment of any other benefits  available  including those under
any  separate  retirement  plans or Medicare)  for  Employee and his  dependents
consistent  with past  practices  up to a cost to  Isolyser  of $1,500  per year
through December 31, 2003 so long as Employee is not in breach of this Agreement
following five days notice of any such breach by Isolyser to Employee.

                  (c) An amount  equal to the value of all accrued  vacation due
to Employee  through the Effective  Date,  as  calculated by Isolyser's  payroll
department. From and after the Effective Date of this Agreement, Employee agrees
that he shall no longer accrue paid absences or be entitled to compensation  for
same.

                  (d)  Isolyser  shall  reimburse  Employee  for all  reasonable
travel and other  business  expenses  incurred by him in the  performance of his
duties and  responsibilities as specifically  requested by Isolyser,  subject to
such  requirements  with respect to  substantiation  and documentation as may be
specified by Isolyser.

         3.       Protective Covenants; Remedies.

                  (a) Property Rights. Employee acknowledges and agrees that all
records of the accounts of customers,  lists,  prospect lists, prospect reports,
vendor lists,  samples,  desk  calendars,  briefcases,  day timers and notebooks
provided by Isolyser or any  subsidiary or affiliate of Isolyser  (collectively,
the "Isolyser  Group"),  policy and procedure  manuals,  price lists,  catalogs,
premises keys,  written methods of pricing,  lists of needs and  requirements of
customers,  written methods of operation of Isolyser Group and any other records
and books  relating in any manner  whatsoever to the customers of Isolyser Group
or  its  business,  whether  prepared  by  Employee  or  otherwise  coming  into
Employee's  possession,  are the exclusive property of Isolyser Group regardless
of who actually purchased or prepared the original book,  record,  list or other
property.  All such books, records, lists or other property shall be immediately
returned by Employee to Isolyser upon any termination of employment.

                  (b)  Non-Disclosure  of  Confidential  Information.   Employee
acknowledges  that  through  formal and  informal  training by  Isolyser  Group,
Employee will become familiar with, among other things, the following:

                           Any  scientific  or  technical  information,  design,
                           process,  procedure,  formula or improvement  that is
                           secret and of value, and information  including,  but
                           not  limited  to,  technical  or  nontechnical  data,
                           formula, patterns,  compilations,  programs, devices,
                           methods,   techniques,    drawings,   processes   and
                           financial  data,   which  Isolyser  takes  reasonable
                           efforts to protect  from  disclosure,  and from which
                           Isolyser  derives actual or potential  economic value
                           due to its  confidential  nature (the foregoing being
                           hereinafter   collectively   referred   to   as   the
                           "Confidential Information").

                  Employee   acknowledges   that   use  of   such   Confidential
Information  will give Employee an unfair  competitive  advantage  over Isolyser
Group in the event that Employee should go into  competition with Isolyser Group
and agrees  that during the term of this  Agreement  and for a period of two (2)
years subsequent to the termination of employment for any reason,  Employee will
not  disclose  to any  person,  or utilize for  Employee's  benefit,  any of the
Confidential   Information.   Employee   acknowledges   that  such  Confidential
Information  is of special and peculiar  value to  Isolyser;  is the property of
Isolyser  Group,  the product of years of experience and trial and error; is not
generally known to Isolyser  Group's  competitors;  and is regularly used in the
operation of Isolyser  Group's  business.  Employee  acknowledges and recognizes
that applicable law prohibits  disclosure of confidential  information and trade
secrets  indefinitely (i.e.,  without regard to the two year period described in
this  paragraph),  and Isolyser has the right to require Employee to comply with
such law in addition to Isolyser's rights under this paragraph.

                  (c)  Non-Interference  With Employees.  Employee agrees not to
solicit,  entice or otherwise induce any employee of Isolyser Group to leave the
employ  of  Isolyser  Group  for any  reason  whatsoever,  and not to  otherwise
interfere with any contractual or business  relationship  between Isolyser Group
and any of its  employees for two (2) years from the  termination  of Employee's
employment.

                  (d)  Inventions.  Employee agrees to fully inform and disclose
to Isolyser all inventions, designs, improvements and discoveries which Employee
now  has or may  hereafter  while  employed  by  Isolyser  obtain  which  either
constitute an improvement to or  modification  of any of the products which from
time to time are under development by Isolyser or being manufactured or marketed
by Isolyser (collectively,  the "Products") or constitute an invention,  design,
improvement  or discovery  having unique  application  to the Products,  whether
conceived  by  Employee  alone or with  others.  All such  inventions,  designs,
improvements  and  discoveries  shall be the  exclusive  property  of  Isolyser.
Employee  shall  assist  Isolyser  to obtain such legal  protection  of all such
inventions,  designs, improvements and discoveries as may be deemed desirable by
Isolyser from time to time.

                  (e)  Non-Solicitation  of  Customers.   Until  two  (2)  years
following  the  termination  of  Employee's  employment,  Employee  agrees  that
Employee will not, within the world (the  "Territory"),  which the parties agree
has been the territory from which Employee has primarily rendered services,  for
Employee's own benefit or on behalf of any other person, partnership, company or
corporation,  contact any customer or  customers of Isolyser  Group who Employee
called  upon  while  employed  by  Isolyser,  for  the  purpose  of  developing,
manufacturing or selling disposable, specialty or safety products for use in the
medical, industrial or commercial markets (collectively, the "Business").

                  (f)  Non-Competition.   Until  two  (2)  years  following  the
termination  of Employee's  employment,  Employee  agrees that Employee will not
within the Territory,  either directly or indirectly on his own behalf or in the
service of others, in any capacity that involves duties similar to the duties of
Employee hereunder, engage in the Business.

                  (g) Acknowledgment  Regarding Protective  Covenants.  Employee
acknowledges and understands that the covenants provided for in this Section are
limited to the covenants set forth herein and do not preclude  Employee upon the
termination of this Agreement  from  obtaining  gainful  employment or utilizing
Employee's  general business skills, and that numerous  opportunities  exist for
Employee to utilize such skills. Although Employee agrees that the time and area
restraints set forth herein are reasonable,  nevertheless, if for any reason now
unforeseen,  a court of competent  jurisdiction  finds that the time and/or area
restraints agreed to herein by the parties are unreasonable then the time and/or
area  restraints  agreed to herein  shall be reduced to an area and/or  duration
deemed  reasonable by such court.  Employee  acknowledges  that the Employee has
read and understands the terms of this Agreement, that the same was specifically
negotiated,  and that the protective  covenants agreed upon herein are necessary
for the  protection  of Isolyser  Group's  business as a result of the  business
secrets  that  will  be  disclosed  during  the  employment.  Further,  Employee
acknowledges  that  Isolyser  would not enter into this  Agreement  without  the
specifically negotiated protective covenants herein stated.

                  (h)  Remedies.  In addition to any other  rights and  remedies
which are available to Isolyser,  with respect to any breach or violation of the
protective covenants set forth herein, it is recognized and agreed that Isolyser
shall be entitled to obtain injunctive relief which would prohibit Employee from
continuing any breach or violation of such protective covenants.

         4. [Intentionally Omitted]

         5. Board Services.  For the remainder of Employee's incumbent term with
such  organizations,  Employee  agrees to continue  to  represent  Isolyser  and
Microtek  through his  appointments  on the  Mississippi  Science and Technology
Commission,   the  Mississippi  State  University   External  Research  Advisory
Commission,  the Ocktibiha  County Hi Tech Business  Development  Board, and the
Mississippi  School  for Math and  Science  Foundation  Board.  Service  on such
organizations  shall not accrue  against  Employee's  agreed  days of service to
Isolyser per year.

         6.  Litigation and  Regulatory  Cooperation.  Employee shall  cooperate
fully with the  Isolyser  Group in the defense or  prosecution  of any claims or
actions  now in  existence  or which may be brought in the future  against or on
behalf  of the  Isolyser  Group  which  relate to  events  or  occurrences  that
transpired while Employee was employed by Isolyser or Microtek.  Employee's full
cooperation in connection with such claims or actions shall include,  but not be
limited to, being  available  to meet with  counsel to prepare for  discovery or
trial  and to act as a  witness  on behalf  of the  Isolyser  Group at  mutually
convenient times. Employee shall also cooperate fully with the Isolyser Group in
connection  with any  examination  or review of any federal or state  regulatory
authority as any such  examination  or review  relates to events or  occurrences
that transpired while Employee was employed by Isolyser or Microtek.

         7.       Miscellaneous.

                  (a)  This  Agreement  and  all of the  terms,  provisions  and
conditions  hereof  shall be binding  upon and/or inure to the benefit of and be
enforceable by the heirs and personal  representatives of Employee and Isolyser;
provided,  that the salary  shall no longer be  payable  and  benefits  shall no
longer accrue after Employee's death.

                  (b) This  Agreement may be executed in multiple  counterparts,
each of which shall be deemed an original and all of which shall  constitute one
and same  agreement.  This  Agreement  contains the full and complete  agreement
between the parties relative to the subject matter hereof.

                  (c) All payments made and benefits  provided to Employee under
this Agreement shall be net of any tax required to be withheld by Isolyser under
applicable law.

                  (d) This  Agreement  shall be governed in accordance  with the
laws of the State of Georgia.






         IN WITNESS  WHEREOF,  the  parties  shall  cause this  Agreement  to be
executed and delivered as of the date first above written.

                             ISOLYSER COMPANY, INC.
