SECOND AMENDMENT TO ASSET PURCHASE AGREEMENT

     THIS  SECOND  AMENDMENT  is made as of the 9th day of March,  2001,  by and
among  Microtek  Medical,  Inc.,  a  Delaware  corporation  ("Purchaser"),  Deka
Medical, Inc., a Florida corporation ("Seller"),  and the stockholders of Seller
set  forth  on  the  signature  page  of  this  Amendment   (collectively,   the
"Stockholders").

                              W I T N E S S E T H:

     WHEREAS, Purchaser, Seller and Stockholders entered into that certain Asset
Purchase  Agreement  dated as of  February 9, 2001,  as amended by that  certain
First  Amendment to Asset Purchase  Agreement dated as of February 23, 2001 (the
"Purchase Agreement"); and

     WHEREAS,  the parties  hereto  desire to amend the  Purchase  Agreement  as
hereinbelow more particularly set forth.

     NOW,  THEREFORE,  for good and  valuable  consideration,  the  receipt  and
sufficiency  of which are  hereby  acknowledged,  the  parties  hereby  agree as
follows:

     1. Defined Terms.  Initially capitalized terms used in this Amendment which
are not  otherwise  defined  in this  Amendment  are used with the same  meaning
ascribed to such terms in the Purchase Agreement.

     2. Amendments.

          (a) The Drape Business Closing Date shall occur  concurrently with the
date of this Amendment,  effective for accounting  purposes at 12:01 a.m., March
3, 2001.  Collected  revenues of the Drape  Business from such time to the Drape
Business Closing Date shall be offset against the Drape Business Cash Payment.

          (b) The text of Section 2.1(b)(i) of the Purchase Agreement is amended
to read as follows:

          "Purchaser  shall pay to or for the account of Seller  $10,383,000  in
          immediately available funds (the "Drape Business Cash Payment"); and"

         Section  2.1(b)(ii) is deleted and Purchaser  shall not issue to Seller
the Note. Section  2.1(b)(iii) is modified to provide that the Key Employee Note
shall not be issued to all the persons identified in Schedule 2.1(b)(iii) of the
Purchase  Agreement  due to the  failure  of  certain  persons  to  satisfy  the
conditions  set forth in such  section,  and to delete the last person  named in
Schedule 2.1(b)(iii).  The aggregate principal amount of such Key Employees Note
shall  accordingly  be  reduced  from $1.25  million to such  amount as shall be
acceptable to Purchaser.

          (c) The form of Key Employees Note attached to the Purchase  Agreement
at Exhibit 2.1(b)(iii) is hereby substituted with the form of Key Employees Note
attached hereto as Exhibit A and incorporated herein by reference.  The terms of
Exhibit  A to the Key  Employees  Note  shall  be set by  Purchaser  in its sole
discretion.

          (d) The text of Section 2.1(c) of the Purchase Agreement is amended to
read as follows:




          The Drape  Business  Purchase  Price shall be  decreased by the amount
          that  Seller's  Working  Capital (as  defined  below)  transferred  to
          Purchaser on the Clean-Op  Closing Date and the Drape Business Closing
          Date (the  "Closing  Working  Capital") is less than  $8,500,000  (the
          "Baseline  Working  Capital").  As  used  herein,  the  term  "Working
          Capital"  means the sum of the current assets of Seller (to the extent
          such  current  assets are included in the  Purchased  Assets which are
          acquired  by  Purchaser  at either the  Clean-Op  Closing or the Drape
          Business  Closing) minus the sum of the Accounts Payable of Seller (to
          the  extent  such  Accounts   Payable  are  included  in  the  Assumed
          Liabilities  (defined in Section  2.2 below)  assumed by Seller at the
          Clean-Op   Closing  or  Drape  Business   Closing)  as  determined  in
          accordance with Generally Accepted Accounting Principles ("GAAP"). For
          purposes of determining Working Capital,  (i) the Accounts Receivables
          shall be that  which  arose in the  ordinary  course  to  creditworthy
          customers  and shall  not be more than 90 days past due in  accordance
          with their terms,  (ii) the inventory shall be that which is currently
          salable or usable in  production  and shall not exceed 12 months usage
          or  sales  except  that  Seller  may add  $650,000  to the  amount  of
          inventory for purposes of calculating  the Closing  Working Capital so
          long as the total amount of inventory  after such  addition  shall not
          exceed $5.0 million,  (iii) in  determining  12 months usage or sales,
          the parties  will take into  consideration  calendar  year 2000 actual
          usage and sales as adjusted for any reasonably  verifiable  forecasted
          increase in sales for the year 2001 or reasonably  expected  sales for
          any new  inventory  not sold in the year 2000,  (iv) for  purposes  of
          determining the market value of finished  goods,  there shall be a 15%
          assumed  disposal  cost  applied to the  applicable  selling  price of
          inventory,  and (v) for  purposes of  determining  the  allocation  of
          overhead to inventory,  the parties will use a method  consistent with
          the method used by Seller at December 31, 2000.  Seller shall  deliver
          to Purchaser at the Drape Business Closing true,  correct and complete
          lists of the Accounts Payable, Accounts Receivable and Inventory as of
          March 2,  2001.  On or before  April 16,  2001,  the  Closing  Working
          Capital shall be reported in reasonable detail by Purchaser to Seller.
          In the event Seller  disagrees with  Purchaser's  determination of the
          Closing Working Capital, then Seller shall notify Purchaser in writing
          within ten (10) business days after receipt of Purchaser's calculation
          of the Closing Working Capital, setting forth in reasonable detail the
          basis for such dispute.  If Seller does not provide such notice within
          such ten (10)  business  day  period,  then the  determination  of the
          Closing  Working  Capital by  Purchaser  shall be final,  binding  and
          conclusive  upon the  parties  hereto.  If Seller  does  provide  such
          notice,  Purchaser and Seller shall attempt in good faith to reconcile
          their  differences  and any  resolution  by  them  as to any  disputed
          amounts  shall be  final,  binding  and  conclusive  upon  each of the
          parties  hereto.  If  Purchaser  and Seller fail to reach a resolution
          within ten (10)  business days after  Purchaser's  receipt of Seller's

                                       2


          written notice of dispute, Purchaser and Seller shall submit the items
          remaining for resolution to KPMG Peat Marwick, LLP ("KPMG"),  Jackson,
          Mississippi  or such other national  accounting  firm as may be agreed
          upon by Purchaser and Seller (the "Independent Accounting Firm") which
          shall  within  thirty (30)  business  days of  submission  resolve and
          report to Seller and Purchaser upon such remaining disputed items, and
          such report shall be final,  binding and  conclusive  upon each of the
          parties hereto. Purchaser and Seller agree that the party which claims
          the greatest variance in the Closing Working Capital from that finally
          determined by the Independent Accounting Firm shall be responsible for
          the fees  and  disbursements  of the  Independent  Accounting  Firm in
          connection with the resolution of such dispute. If any amounts are due
          to  Purchaser  under  this  Section  2.1(c),   Seller  shall  pay  the
          applicable  amount due under this  Section  in  immediately  available
          funds within five (5) days following its  determination by the parties
          or  the  Independent  Accounting  Firm,  or at  Purchaser's  election,
          Purchaser may withdraw from the Escrow Fund (as defined  below) in the
          amount due  Purchaser  under this  Section  2.1(c)  together  with any
          earnings  on such  amount  withdrawn  from the Escrow  Fund (with such
          earnings to  compensate  Purchaser for the loss of use of funds during
          the period of determining the Working Capital Adjustment).

          (e) At the Drape Business  Closing $1.5 million (the "Escrow Fund") of
the Drape  Business  Cash Payment shall be paid by Purchaser to the Escrow Agent
named in and to be held under the Escrow  Agreement in the form attached  hereto
as Exhibit "B" and  incorporated  herein by  reference to secure the payment and
performance  by Seller and the  Shareholders  of their  obligations to Purchaser
under the Purchase  Agreement,  as amended hereby. The Escrow Fund shall be held
in  accordance  with the  Escrow  Agreement  until the later to occur of (i) the
resolution of the Working  Capital  adjustment in accordance with Section 2.1(c)
of the  Purchase  Agreement,  (ii)  completion  of the  transition  services  in
accordance  with  Section  5.16 of the  Purchase  Agreement,  (iii)  eight weeks
following the date hereof,  (iv) the date of resolution and  satisfaction of any
claims for  indemnification  of which  Purchaser  has given  Seller a reasonably
detailed  notice in accordance  with Article 6 hereof prior to the last to occur
of the events described in the preceding clause (i) through (iii).

          (f) Seller hereby  grants to Purchaser the exclusive  right and option
to purchase  from Seller all or  substantially  all of the assets (the "Gel Lite
Assets")  of Seller  used or held for use by Seller  in its  gel-filled  pad and
cover business (the "Gel Lite Business"). In the event Seller elects to purchase
the Gel Lite Assets, the purchase price of the Gel Lite Assets shall be $200,000
in immediately available funds payable to or for the account of Seller (the "Gel
Lite  Purchase  Price").  On or before March 12, 2001,  Seller shall prepare and
deliver to Purchaser an addendum to the Schedules attached to and forming a part
of the Purchase Agreement and such other schedules, documents and materials with
respect  to the Gel Lite  Assets  and the Gel Lite  Business  in order  that the
representations  and  warranties of Seller  contained in the Purchase  Agreement
shall  remain  true,  correct and  complete as though the Gel Lite  Business was
included  within the Drape Business and the Gel Lite Assets were included within
the Purchased  Assets.  Purchaser  shall have the right to purchase the Gel Lite
Assets by giving notice to Seller within two weeks after Purchaser's  receipt of
such disclosures from Seller.  In the event Purchaser does purchase the Gel Lite
Assets  from  Seller,  then  the Gel  Lite  Assets  will be  deemed  part of the
Purchased  Assets (and  Schedule 1.2 shall be modified so that such assets shall
not be deemed Excluded  Assets),  there shall be no Working  Capital  adjustment
with  respect to the Gel Lite  Business  as  provided  in Section  2.1(c) of the
Purchase  Agreement,  all  representations  and warranties made by Seller in the
Purchase Agreement with respect to the Drape Business shall be deemed to be made
by Seller with  respect to the Gel Lite  Business,  Seller and the  Shareholders
shall have the same  indemnification  obligations  with  respect to the Gel Lite
Business  that it has or they have in the  Purchase  Agreement as though the Gel


                                       3


Lite Business was the Drape Business, and Seller and Purchaser shall execute and
deliver  appropriate  documents for the consummation of the purchase and sale of
the Gel Lite Assets as  provided  in Articles 7 and 8 with  respect to the Drape
Business on or before two weeks  after  Purchaser's  receipt of the  disclosures
from Seller described above.

          (g) To the  extent  that  Seller  has  not  caused  the  1999  Audited
Financial  Statements to be completed  and  delivered to Purchaser  prior to the
Drape Business Closing, Seller shall cause same to be completed and delivered to
Purchaser as soon as possible after the Drape  Business  Closing and in no event
later than May 4, 2001.

          (h) Section  5.16(b) of the Purchase  Agreement is amended by deleting
the cost per week for the transition  services provided for therein for Columbus
at $7,000 per week and for  Jacksonville  at $5,000 per week,  and  inserting  a
total  maximum  payment  obligation  of $106,000 by  Purchaser to Seller for all
transition  services set forth in such Section  5.16(b) to be provided by Seller
to  Purchaser,  and to provide  that such  services  shall be made  available by
Seller to  Purchaser  until at least April 30, 2001 unless  otherwise  agreed by
Seller and Purchaser.  The payment for the transition  services shall be payable
weekly in advance and shall equal,  subject to the maximum set forth above,  the
overhead expenses of Seller in maintaining transitional operations as reasonably
requested by  Purchaser  in Seller's  facilities  in  Jacksonville,  Florida and
Columbus, Mississippi.

          (i) Schedule 1.2 of the Purchase Agreement is hereby amended by adding
to such Schedule the following:

          "7.  Exclusive  Distributorship  Agreement  dated May 5, 2000  between
          Seller and Worldwide  Innovations &  Technologies,  Inc. (the "Rad Pad
          Agreement").

          (j)  Schedule  3.7 of the  Purchase  Agreement  is hereby  deleted and
Exhibit "C" attached hereto and incorporated  herein by reference is inserted in
lieu thereof.

          (k)  Schedule  3.16 of the  Purchase  Agreement  is hereby  amended by
adding to the Drape Business  Agreements  appearing in such schedule the Rad Pad
Agreement.

          (l)  Section  6.5 of the  Purchase  Agreement  is  hereby  amended  by
deleting  the term "Note"  appearing  therein and  inserting in lieu thereof the
term "Escrow Fund".

          3.  Miscellaneous.  Except as modified and amended hereby, the parties
hereto adopt and ratify the Purchase  Agreement without further  modification or
amendment. This Amendment may be executed in any one or more counterparts,  each
of which shall be deemed an original but all of which shall together  constitute
one and the same agreement.

Holder and Microtek Medical, Inc. ("Microtek"),  dated as of ____________,  2001
(the "Asset Purchase Agreement"). Any and all payments under this Debenture, and
the  conversion  of any portion of this  Debenture  into  Conversion  Shares (as
defined  below),  shall be contingent  upon the achievement of the sales revenue
goals attached as Exhibit "A" hereto and Holder's  employment with Microtek from
the date hereof on and through the Maturity Date.

     2. Prepayment.

          2.1 Right to  Prepay.  Isolyser  may at any time and from time to time
prepay the stated  principal  amount of the Debenture or any portion  thereof as
hereinbelow  set forth.  The amount  prepaid (the "Prepaid  Face Amount")  shall
equal such Prepaid Face Amount discounted to its present value on the Prepayment
Date (as defined  below)  using a discount  rate of 10% per year (the  "Discount
Rate") from the Maturity Date (such  discounted  amount being referred to herein
as the "Discounted Prepaid Face Amount").

                                       8


          2.2 Obligation to Prepay. Subject to the other terms and provisions of
the Debenture,  Isolyser shall prepay the Prorated Portion (as defined below) of
the stated  principal  amount of the Debenture in the event Holder's  employment
with  Microtek is  terminated  prior to the Maturity Date either (i) by Microtek
without cause (as the term cause is defined in any written employment  agreement
between  Microtek and Holder) or (ii) due to the death or  disability of Holder.
The term  "Prorated  Portion"  means the period of time  Holder was  employed by
Microtek after the date of this Debenture as compared to four years.  The amount
required  to be paid in  satisfaction  of this  Debenture  in the  event of such
prepayment  shall equal the Prorated  Portion of the stated  principal amount of
the Debenture  discounted to its present value on the Prepayment  Date using the
Discount Rate from the Maturity Date (also  referred to herein as the Discounted
Prepaid Face  Amount).  Any  prepayment  under this Section 2.2 shall occur on a
date  selected  by  Isolyser as provided in Section 2.3 which shall be not later
than thirty (30) days after the date of such termination of employment.

          2.3 Notice.  At least  fifteen  (15) days prior to the desired date of
any prepayment of the Debenture (the "Prepayment Date"), written notice shall be
delivered  to the Holder at its address  last shown on the records of  Isolyser,
notifying  the Holder of the  election of Isolyser to prepay the  Debenture,  in
whole or in part, specifying in such notice the Prepayment Date, and stating the
Prepaid  Face Amount and the  Discounted  Prepaid  Face Amount  (such  notice is
hereinafter referred to as the "Prepayment Notice").

          2.4 Surrender of Debenture. On or prior to the Prepayment Date, unless
Holder shall have  converted the  Debenture as provided in Section 4 below,  the
Holder shall surrender this Debenture, in the manner and at the place designated
in the Prepayment Notice, and thereupon the Discounted Prepaid Face Amount shall
be payable to the order of the  Holder  and the  Debenture,  if prepaid in full,
shall be  canceled.  In the  event  the  Debenture  is  prepaid  in part,  a new
debenture  shall be issued  to Holder to  reflect  the  partial  prepayment  and
reduction of principal.

     3.  Events of Default.  If any of the events  specified  in this  Section 3
shall occur (an "Event of Default"),  the entire  principal  and unpaid  accrued
interest  hereon  shall become  immediately  due and payable if the Holder gives
notice to Isolyser of its election to declare a default hereunder as a result of
any of the following:

                  (i)  Isolyser  fails to pay the unpaid  principal  on any date
         due, and does not cure such failure  within thirty (30) days of receipt
         of written notice of such nonpayment; or

                  (ii)  Isolyser   makes  an  assignment   for  the  benefit  of
         creditors,  or any  proceeding  is  instituted  by or against  Isolyser
         alleging that it is bankrupt or insolvent;  provided  however,  that if
         any such  proceeding is instituted  against  Isolyser by a third party,
         such event shall not constitute an Event of Default if dismissed within
         ninety (90) days.

     4. Conversion.

          4.1 Election by Holder.  The Holder has the right on the Maturity Date
to convert  this  Debenture,  in whole or in part,  and in  accordance  with the
provisions of Subsection 4.2 hereof, into fully paid and nonassessable shares of
the Common  Stock of  Isolyser  (the  "Common  Stock").  The number of shares of
Common  Stock  into which  this  Debenture  may be  converted  (the  "Conversion
Shares") on the Maturity  Date shall be determined by dividing (a) the principal
amount  of the  Debenture  to be  converted  at the  Maturity  Date  by (b)  the


                                       9


Conversion Price. As used herein, the term "Conversion Price" shall mean a price
of $2.50,  which Conversion Price shall be subject to adjustment as set forth in
Section  5. In  addition,  in the event of a Change of  Control  (as  defined in
Isolyser's  1999 Long Term Incentive  Plan),  the Holder shall have the right to
convert the  Debenture  in  accordance  with the terms  hereof  into  Conversion
Shares, except the principal face amount hereof to be converted shall be reduced
to its present value as of the date of such conversion using the Discount Rate.

          4.2  Conversion  Procedure.  At least  fifteen  (15) days prior to the
Maturity Date,  the Holder shall deliver to Isolyser  written notice in the form
attached hereto as Exhibit "B" (the "Conversion Notice"),  stating the principal
amount of the  Debenture  desired to be  converted  and the number of  resulting
Conversion Shares. Upon its receipt of the Conversion Notice,  Isolyser,  at its
option,  may  provide to the Holder as a  condition  to  Isolyser's  obligations
hereunder,  such  disclosures  of  material,  nonpublic  information  as  may be
necessary or desirable in the discretion of Isolyser for Isolyser to comply with
any applicable  federal or state securities laws, rules, or regulations,  all of
which   information   shall  be  held  and  used  by  Holder  according  to  any
confidentiality and nondisclosure obligation or provisions required by Isolyser.
On or prior to the receipt of any Conversion  Shares, the Holder shall surrender
this  Debenture,  in the manner and at the place  designated  by  Isolyser,  and
thereupon the Conversion Shares shall be issued to the Holder and the Debenture,
if  converted  in full,  shall be  canceled.  In the event only a portion of the
Debenture is converted,  the remainder of the principal  amount of the Debenture
shall be paid  according to the terms  hereof.  Any  conversion of the Debenture
shall be deemed to have been made immediately  prior to the close of business on
the  date of  Holder's  surrender  of this  Debenture  and  its  receipt  of the
Conversion  Shares, and the person or persons entitled to receive the Conversion
Shares shall be treated for all purposes as the record holder or holders of such
Conversion Shares as of such date.

          4.3 No Fractional  Shares.  No fractional shares of Common Stock shall
be issued upon conversion of this  Debenture.  Upon conversion of this Debenture
and the proper  issuance of the  Conversion  Shares,  Isolyser  shall be forever
released from all its obligations  and  liabilities  under this Debenture to the
extent of the Conversion Face Amount.

     5. Conversion Price Adjustments.

          5.1  Adjustments  for  Stock  Splits  and  Subdivisions.  In the event
Isolyser  should  at any time or from time to time  after  the date of  issuance
hereof fix a record date for the  effectuation  of a split or subdivision of the
outstanding  shares of Common  Stock or the  determination  of holders of Common
Stock entitled to receive a dividend or other distribution payable in additional
shares of  Common  Stock or other  securities  or rights  convertible  into,  or
entitling  the holder  thereof to receive  directly  or  indirectly,  additional
shares of Common Stock (hereinafter  referred to as "Common Stock  Equivalents")
without payment of any consideration by such holder for the additional shares of
Common Stock or the Common Stock Equivalents (including the additional shares of
Common Stock  issuable upon  conversion or exercise  thereof),  then, as of such
record date (or the date of such dividend distribution,  split or subdivision if
no record  date is  fixed),  the  Conversion  Price of this  Debenture  shall be
appropriately  decreased so that the number of shares of Common  Stock  issuable
upon  conversion  of this  Debenture  shall be increased in  proportion  to such
increase of outstanding  shares.  If the Conversion Price is adjusted under this
Section 5.1 but the dividend  distribution,  split or subdivision  which was the
basis  for  such  adjustment  is  ultimately  abandoned  by  Isolyser,  then the
Conversion  Price  shall be  readjusted  to offset the  effect of such  previous
adjustment.

          5.2 Adjustments  for Reverse Stock Splits.  If the number of shares of
Common  Stock  outstanding  at any time after the date hereof is  decreased by a
combination  of the  outstanding  shares of Common  Stock,  then,  following the


                                       10


record date of such  combination,  the Conversion Price for this Debenture shall
be appropriately increased so that the number of shares of Common Stock issuable
on  conversion  hereof  shall be  decreased in  proportion  to such  outstanding
shares.

          5.3 Reservation of Stock Issuable upon  Conversion.  Isolyser shall at
all times reserve and keep available out of its  authorized but unissued  shares
of Common  Stock such number of its shares of Common Stock as shall from time to
time be sufficient to effect the full conversion of the Debenture.

     6. Subordination.

          6.1 Definitions.  "Senior  Indebtedness" means (i) Isolyser's existing
outstanding   indebtedness   and   credit   facilities   (excluding   any  trade
indebtedness) ("Existing Indebtedness"),  including, without limitation, (A) any

such Credit Agreement), and any modifications, renewals, extensions, amendments,
supplements or  restatements of any of the foregoing,  and (B) any  indebtedness
incurred by Isolyser to replace the loans  identified in (A) or  constituting an

this Debenture to the contrary,  Isolyser hereby covenants and agrees,  and each
holder hereof, by its acceptance thereof, likewise covenants and agrees that the
indebtedness  evidenced  by this  Debenture  and the  payment  of the  principal
thereof  and  interest  thereon  and  all  other  amounts  payable  under  or in
connection  with  this  Debenture  (the  "Subordinated  Indebtedness")  shall be
subordinate  and  subject in right of  payment,  to the extent and in the manner
hereinafter set forth, to the prior indefeasible  payment in full in cash of all
Senior Indebtedness (as hereinafter defined), and that such subordination is for
the benefit of the holders of Senior Indebtedness.

          6.3 Distribution on Dissolution, Etc. In the event of any voluntary or

proceedings for liquidation,  dissolution or other winding up of Isolyser or any
assignment   for  the  benefit  of  creditors  or   marshalling  of  assets  and
liabilities, whether or not involving insolvency or bankruptcy, then the holders
of Senior  Indebtedness  shall be entitled to receive payment in full in cash of

payable or deliverable in respect of this Debenture,  including any such payment
or  distribution  which may be payable or  deliverable by virtue of any security
for, or by virtue of the  provisions  of (or any  security  for) any  securities

          or other  documents  evidencing such Senior  Indebtedness,  and in the
          event of any Payment Default,  the Holder shall not (A) ask, demand or

          the Credit Agreement, or otherwise; (iv) any requirements of diligence
          on the part of any holder of any of the Senior  Indebtedness;  (v) any

          mitigate  damages   resulting  from  any  default  under  such  Senior
          Indebtedness or the Credit Agreement; and (vi) any notice of any sale,
          transfer or other disposition of any Senior Indebtedness by any holder
          thereof.

               6.5.3  Continued  Effect.  The  obligations of the Holder of this
          Debenture under the subordination provisions contained in this Section
          6 shall continue to be effective,  or be  reinstated,  as the case may
          be, if at any time any  payment in respect of any Senior  Indebtedness
          or any other payment to any holder of any Senior  Indebtedness  in its
          capacity  as such,  is  rescinded  or must  otherwise  by  restore  or
          returned by the holder of such Senior Indebtedness upon the occurrence
          of any litigation or other proceeding,  or upon, or as a result of the
          appointment of a receiver,  intervenor, or any substantial part of its
          property, or otherwise,  all as though such payment had not been made.
          The subordination  provisions contained in this Section 6 shall be for
          the  benefit of all holders of Senior  Indebtedness  from time to time
          outstanding,  and each of such  holders  may  proceed to enforce  such
          provisions  either directly against the holder of this Debenture or in
          any  other  manner  provided  by law and  without  the  need to  prove
          reliance  on the  subordination  hereof.  As  used  herein,  the  term
          "holders" of any indebtedness  shall include any trustee for, or other
          authorized  representative of, the holders of such  indebtedness.

          6.6 Further  Assurances;  Limitation on Actions.  Notwithstanding  the
subordination  provisions of this Section 6, the Holder  covenants and agrees to
execute and deliver any other  documents,  instruments,  or  certificates  which
might reasonably be requested or required by the present or future holder of the


                                       13


Senior Indebtedness,  including,  without limitation, a separate and independent
Subordination  Agreement.  The Holder of this  Debenture  by  acceptance  hereof
agrees and  undertakes  that it will not take,  obtain or hold (or permit anyone
acting on its behalf to take, obtain or hold) any assets of Isolyser, whether as
administrative,  legal or equitable  action,  or otherwise,  in violation of the
provisions of the subordination provisions set forth in this Section 6.

          6.7 Obligations Not Impaired.  Nothing  contained in this Section 6 is
intended  or shall  impair as between  Isolyser,  its  creditors  other than the
holders of Senior Indebtedness, and the Holder of this Debenture, the obligation
of Isolyser, which shall be absolute and unconditional,  to pay to the Holder of
the Note the principal on this Debenture,  as and when the same shall become due
and payable in accordance  with its terms,  or to affect the relative  rights of
the Holder of this Debenture and creditors of Isolyser other than the holders of
Senior  Indebtedness,  nor shall  anything  herein  prevent  any  Holder of this
Debenture from  exercising all remedies  otherwise  permitted by applicable law,
upon  default,  subject to the rights,  if any,  under these  provisions  of the
holders of Senior  Indebtedness  in respect of cash,  property or  securities of
Isolyser received upon the exercise of any such remedy.

     7. Assignment. Subject to the restrictions on transfer described in Section
9 below,  the rights and obligations of Isolyser and the Holder shall be binding
upon and benefit the successors,  assigns, heirs, administrators and transferees
of the parties.

     8. Waiver and  Amendment.  Any provision of this  Debenture may be amended,
waived or modified only upon the written consent of Isolyser and the Holder.

         This Conversion  Notice (the "Conversion  Notice") is given pursuant to
Section 4.2 of that certain Contingent Subordinate Convertible Debenture,  dated
as of __________,  2001, in the principal face amount of  $____________________,
from Isolyser Company,  Inc.  ("Isolyser") (the "Debenture").  Capitalized terms
used in this  Conversion  Notice and not defined  herein shall have the meanings
ascribed to them in the Debenture.  The undersigned desires to convert as of the

         The undersigned hereby covenants,  represents, and warrants to Isolyser
as  follows,  and  acknowledges  that each such  covenant,  representation,  and
warranty  is  material  to and  intended  to be relied  upon by  Isolyser in its
issuance of the Conversion Shares.

         1. The  undersigned is acquiring the  Conversion  Shares solely for the
undersigned's  own  account  for  investment  purposes  and  not  with a view or
interest of participating, directly or indirectly, in the resale or distribution
of all or any part thereof.

         2. The undersigned is a resident of the State of _______________.

         3. The undersigned  acknowledges that all Conversion Shares acquired by

Securities Act of 1933, as amended, and in reliance upon certain exemptions from
registration requirements under applicable state securities laws.

         4. The  undersigned  will make no transfer or  assignment of any of the

                  The  shares  represented  by this  certificate  have  not been
         registered  under the Securities Act of 1933, as amended,  or under the
         securities laws of any other jurisdiction,  in reliance upon exemptions
         from the registration requirements of such laws. The shares represented
         by this certificate may not be sold or otherwise transferred,  nor will


                                       17


         an assignee or endorsee  hereof be recognized as an owner of the shares
         by the issuer unless: (i) a registration statement under the Securities
         Act of 1933 and other  applicable  securities  laws with respect to the
         shares and the transfer shall then be in effect; or (ii) in the opinion
         of counsel  satisfactory to the issuer, the shares are transferred in a
         transaction which is exempt from the registration  requirements of such
         laws.

         6. The  undersigned  is aware that no federal or state  agency has made
any  recommendation  or endorsement  of the Conversion  Shares or any finding in
such Conversion Shares.

         7. Neither Isolyser nor any person acting on its behalf has offered the
Conversion Shares to the undersigned by means of general or public  solicitation
or  general  or  public   advertising,   such  as  by   newspaper   or  magazine
advertisements, by broadcast media, or at any seminar or meeting whose attendees
were solicited by such means.

         8.  The  undersigned  has  reviewed  the  periodic  reports  and  proxy
statements filed by Isolyser with the Securities and Exchange Commission ("SEC")
and press releases issued by Isolyser,  and acknowledges  that Isolyser has made
available to the  undersigned  the  opportunity  to ask questions and to receive
answers, and to obtain information necessary to evaluate the merits and risks of
this  investment.  To the extent  Isolyser  has provided  the  undersigned  with
certain disclosures of material nonpublic information related to Isolyser,  such
information  shall be held in the strictest  confidence by the  undersigned  and
shall not be divulged, communicated, used to the detriment of Isolyser, nor used
for  the  improper  benefit  of  any  business,  firm,  person,  partnership  or
corporation, or otherwise misused in any manner.

         9. The undersigned hereby acknowledges that the Conversion Shares are a
speculative investment. The undersigned represents that the undersigned can bear
the economic risks of such an investment for an indefinite period of time.

         10.  The  undersigned  hereby   acknowledges  and  represents  that  no
commission or other  remuneration  has been paid or given directly or indirectly
in  connection  with  the  offer  or  sale  of  the  Conversion  Shares  to  the
undersigned.

         11. The  undersigned  has full legal power and authority to execute and
deliver, and to perform the undersigned's  obligations under, this agreement and
such  execution,  delivery  and  performance  will not  violate  any  agreement,
contract, law, rule, decree, or other legal restriction by which the undersigned
is bound.

         12. The undersigned shall not sell,  transfer,  or otherwise dispose of
any of the  Conversion  Shares  without  first  offering  them for  purchase  to
Isolyser,  which shall have the right,  at its sole  option,  to  purchase  such
Conversion  Shares at a price per share equal to the closing price of the Common
Stock of Isolyser as of the close of trading on the date  immediately  preceding
Isolyser's  purchase.  A legend to such  effect may be placed by Isolyser on the
certificate or certificates representing the Conversion Shares.

         13. The  undersigned  acknowledges  that  Isolyser is relying  upon the
representations  and  covenants  of the  undersigned  contained  herein  for the
purpose  of  complying  with  federal  and state  securities  laws and for other
purposes,  and agrees to indemnify and hold harmless  Isolyser,  and each of its


                                       18


officers and directors,  from and against any and all loss, damage, or liability
(including,  without limitation, court costs and reasonable attorney's fees) due
to or  arising  from a  breach  of any  representation,  warranty,  or  covenant
contained in this Agreement.

         The undersigned  agrees to surrender the Debenture in the manner and at
the place designated by Isolyser, after which surrender Isolyser shall issue the
Conversion Shares, and the Debenture,  if converted in full, shall be cancelled.
In the event only a portion of the Debenture is being converted,  Isolyser shall
pay  such  remaining  amount  to the  undersigned  on  the  Maturity  Date.  All
Conversion  Shares  shall be deemed to have been made  immediately  prior to the
close of business on the date of Holder's  surrender of this  Debenture  and its
receipt of the Conversion  Shares, and the person or persons entitled to receive
the Conversion  Shares shall be treated for all purposes as the record holder or
holders of such Conversion Shares as of such date.

         This  Conversion  Notice is given as of the date set forth above by the
undersigned.

                                   WITNESSETH:

         WHEREAS,  pursuant to a separate Asset Purchase  Agreement  dated as of
February 9, 2001, as amended (the "Purchase  Agreement") between Microtek,  Deka
and certain  stockholders of Deka, Microtek and Deka wish to establish an escrow
account to secure the obligations of Deka under the Purchase Agreement.

         NOW, THEREFORE, for valuable consideration, the receipt and sufficiency
of which is hereby acknowledged,  and intending to be legally bound, the parties
hereto do hereby agree as follows:

                                    ARTICLE I
                                   DEFINITIONS

         Unless otherwise defined herein,  capitalized terms used in this Escrow
Agreement have the definitions set forth in the Purchase Agreement.

                                   ARTICLE II
                                 THE ESCROW FUND

         2.1 Delivery.  Simultaneously  with the execution  hereof,  Microtek is
depositing  with Escrow Agent the sum of  $1,500,000  (the "Escrow  Fund") to be

accordance  with the terms and  conditions of this Escrow  Agreement and for the
uses and purposes stated herein.

         2.3  Investment.  Escrow Agent shall,  pending the  disbursement of the
Escrow Fund  pursuant to this  Escrow  Agreement,  invest any cash in the Escrow

         (a)  interest  bearing  savings  accounts  (the  terms of which have no

Provided,  that, all such investments can be liquidated  without penalty to cash
promptly in order to allow timely  disbursement  of cash in accordance with this
Escrow Agreement.

                                   ARTICLE III
                 PROCEDURES FOR DISBURSEMENT OF THE ESCROW FUND

         The following  procedures  shall govern the  distribution of the Escrow
Fund by Escrow Agent.

         3.1  Notice of  Claims.  Subject to  Sections  3.2 and 3.3 below,  upon
receipt  of  notice  from  either  Microtek  or Deka (the  "Notice")  that it is
entitled  to a payment and the amount  thereof,  along with a copy of the Notice
sent to the other Party, the Escrow Agent shall, not less than ten days nor more
than 15 days following receipt of such Notice,  disburse to the party delivering
such  Notice an amount  equal to the  lesser of (i) the  balance  thereof in the
Escrow Fund or (ii) the amount specified in the Notice. Any notice shall specify
with reasonable  detail the reasons why the requesting party is entitled to such
disbursement.

         3.2 Notice of Dispute. Notwithstanding the foregoing, in the event that
either Deka or Microtek objects to the disbursement of any portion of the Escrow
Fund,  such objecting  party shall so notify Escrow Agent not more than nine (9)
days from the date of the Notice.  Any objection  shall specify with  reasonable
detail the reasons why the  objecting  party is objecting  to the  disbursement.
Such a dispute shall be resolved in the manner set forth in Section 3.5 below.

         3.3 Uncertainty.  In the event that Escrow Agent, in good faith,  shall
be in doubt as to what action it should take hereunder, Escrow Agent may, at its
option,  refuse to comply with any claims or demands on it or refuse to take any
other action  hereunder,  so long as such  disagreement  continues or such doubt
exists; and in any such event, Escrow Agent shall not be or become liable in any
way or to any person for its failure or refusal to act,  and Escrow  Agent shall
be entitled to continue to so refrain  from acting  until it has  received (a) a
nonappealable court order from a court of competent  jurisdiction  directing the
disposition of such property,  (b) a signed arbitration award in accordance with
Section 3.5 hereof or (c) appropriate  written  instructions signed by both Deka
and Microtek.

         3.4 Time of  Essence.  The  parties  agree that time is of the essence
with respect to all deliveries referenced in this Article III.

                                       22


         3.5  Resolution of Disputes.

         (a) Any dispute  between the parties arising out of or relating to this
Escrow  Agreement  shall be resolved by  arbitration  in  Atlanta,  Georgia,  in
accordance  with the Commercial  Arbitration  Rules of the American  Arbitration
Association  ("AAA") in effect at the time the demand for  arbitration is filed.
The AAA rules shall  govern the  enforcement  of this Article only to the extent
the rules do not conflict with these express  provisions.  One arbitrator  shall
hear the  dispute.  Such  arbitrator  shall  be a  retired  judge or  practicing
attorney  with at least twenty years of  experience  in business and  commercial
law.

         (b) To commence  arbitration,  Microtek or Deka shall file with the AAA
and serve a demand for  arbitration in accordance with the applicable AAA rules.
Any such demand shall  include a reasonably  detailed  description  of the facts
forming the basis of the demand and shall specify the relief or remedy sought.

         (c) The  parties   recognize  and agree  that  interstate  commerce  is
involved, and the parties agree that enforcement of their agreement to arbitrate
and any arbitration  award entered pursuant to this agreement to arbitrate shall
be pursuant to the Federal  Arbitration  Act, 9  U.S.C.ss.1,  et. seq.,  and not
pursuant to any state arbitration statute.

         (d) The award shall be final and binding upon the parties, and judgment
may be entered upon it in any court having jurisdiction thereof.

         (e) The  non-prevailing  party in the arbitration  proceeding shall pay
the reasonable  attorney's  fees of the prevailing  party in the arbitration and
the cost of all  arbitrators'  compensation  and AAA  assessed  expenses  of the
arbitration.  If the  arbitrator  does  not  determine  that  one  party  is the
prevailing or  non-prevailing  party, then the parties shall each bear their own
expenses and attorney's fees in any arbitration,  and both parties shall equally
bear the cost of all arbitrators'  compensation and AAA assessed expenses of the
arbitration.

                                   ARTICLE IV
                                  ESCROW AGENT

         4.1 Appointment. Microtek and Deka hereby appoint Escrow Agent to serve
hereunder,  and Escrow  Agent  hereby  accepts  such  appointment  and agrees to
perform all duties which are expressly set forth in this Escrow Agreement.

         4.2  Compensation.  Escrow  Agent will be entitled to  compensation  in
accordance  with its customary fee schedule,  a copy of which is attached hereto
at Exhibit A. Microtek and Deka shall each pay half of the Escrow Agent's fees.

         4.3  Resignation.  Escrow  Agent may resign at any time upon giving the
other parties hereto 30 days' prior written  notice.  In such event,  the acting
Escrow Agent shall  deliver the Escrow Fund and any and all  documents  relating
thereto then in its  possession to a successor  Escrow  Agent;  the successor to
Escrow  Agent shall be such  person,  firm or  corporation  as shall be mutually
agreed upon by Microtek and Deka. Such resignation  shall not be effective until
a successor agrees to act hereunder;  provided, however, that if no successor is


                                       23


appointed and acting hereunder within 30 days after such notice is given, Escrow
Agent may pay and deliver the Escrow Fund into a court of competent jurisdiction
and shall have no further responsibility  hereunder.  Such resignation shall not
deprive the Escrow Agent of the compensation earned prior thereto.

                                    ARTICLE V
                 LIABILITIES AND INDEMNIFICATION OF ESCROW AGENT

         Escrow Agent shall not liable for any damages,  or have any obligations
other  than the  duties  prescribed  herein in  carrying  out or  executing  the
purposes and intent of this Escrow Agreement;  provided,  however,  that nothing
herein  contained  shall relieve Escrow Agent from liability  arising out of its
own  willful   misconduct  or  gross  negligence.   Escrow  Agent's  duties  and
obligations under this Escrow Agreement shall be entirely administrative and not
discretionary.  Escrow  Agent shall not be liable to any party  hereto or to any
third party as a result of any action or omission  taken or made by Escrow Agent
in good faith. The parties to this Escrow Agreement shall at their joint expense
(one-half by Microtek  and  one-half by Deka),  indemnify,  hold  harmless,  and
reimburse Escrow Agent and its officers, directors, employees, and agents, from,
against and for,  any and all  liabilities,  costs,  fees,  claims,  damages and
expenses (including reasonable attorneys' fees) Escrow Agent may suffer or incur
by reason of its  execution and  performance  of this Escrow  Agreement.  In the
event any legal questions arise concerning Escrow Agent's duties and obligations
hereunder,  Escrow Agent may consult its counsel and rely without liability upon
written opinions given to it by such counsel.

         Escrow  Agent shall be  protected  in acting  upon any written  notice,
request, waiver, consent, authorization, or other paper or document which Escrow
Agent, in good faith, believes to be genuine and what it purports be.

                                   ARTICLE VI
                                   TERMINATION

         This Escrow  Agreement  shall be terminated  (a) upon  disbursement  or
release of the entire  Escrow Fund by the Escrow  Agent,  (b) by written  mutual
consent  signed  by  all  parties,  (c)  upon  receipt  by  Escrow  Agent  of an
arbitration  award to that effect in  accordance  with Section 3.5 hereof or (d)
upon  receipt by Escrow  Agent of a  nonappealable  order to that  effect from a
court of competent  jurisdiction.  This Escrow  Agreement shall not be otherwise
terminated.

                                   ARTICLE VII
