     Sellers  a  calculation  of  Protocol's  Adjusted  EBITDA  for  each of the
     immediate preceding two (2) years (the "SECOND ANNIVERSARY ACTUAL EBITDA").
     If the average of the two (2) years of the Second Anniversary Actual EBIDTA
     (the "SECOND ANNIVERSARY AVERAGE EBITDA") is not at least Two Hundred Fifty
     Thousand  ($250,000),  then the Preliminary Purchase Price shall be reduced
     by an amount equal to one hundred percent (100%) of the difference  between
     Two Hundred Fifty Thousand  Dollars  ($250,000) and the Second  Anniversary
     Average EBITDA and the principal amount  outstanding under the Buyers Notes
     shall be  reduced,  pro rata to the  principal  outstanding  on each of the
     Buyers Notes,  by one hundred  percent  (100%) of the  difference,  if any,
     between  Two  Hundred  Fifty  Thousand  Dollars  ($250,000)  and the Second
     Anniversary Average EBITDA.

          (iii) THIRD ANNIVERSARY CALCULATIONS.  On the third anniversary of the
     Closing  Date,  the  Buyers  will  prepare  and  deliver  to the  Sellers a
     calculation of Protocol's Adjusted EBITDA for the immediately preceding one
     (1) year period  (the  "THIRD  ANNIVERSARY  ACTUAL  EBITDA").  If the Third
     Anniversary Actual EBITDA is not equal to or greater than Two Hundred Fifty
     Thousand Dollars  ($250,000.00) (the "THIRD ANNIVERSARY  PROTOCOL EBITDA"),
     then the Preliminary Purchase Price and the principal amounts due under the
     remaining  Buyers  Notes  shall  be  reduced,  pro  rata  to the  principal
     outstanding on each of the Buyers Notes,  by an amount equal to one hundred
     percent (100%) of the  difference,  if any,  between the Third  Anniversary
     Protocol EBITDA and the Third Anniversary Actual EBITDA.

     aggregate  amount of  $40,500.00  loan  reflected on  Protocol's  books and
     records as due to Protocol from Florcor

          (viii) If applicable,  Protocol shall have  transferred to Flowers all
     relevant  life  insurance  polic(ies)  owned  by  Protocol  on the  life of
     Flowers.

The Sellers may waive any condition  specified in this ss.6(b) if they execute a
written statement so stating at or prior to the Closing.

had reason to know of any misrepresentation or breach of warranty or covenant at

representations  and  warranties  set forth in Section  3(a)(vi)  shall  survive

                                      -21-
<PAGE>
     (b) INDEMNIFICATION  PROVISIONS FOR BENEFIT OF THE BUYERS. In the event the
Sellers breach any of their representations, warranties, and covenants contained
herein,  and,  if there is an  applicable  survival  period  pursuant to ss.7(a)
above, provided that any of the Buyers makes a written claim for indemnification
against the Sellers pursuant to ss.11(h) below within such survival period, then
Flowers solely agrees to indemnify, subject to all limitations contained herein,
each of the Buyers  from and against  any  Adverse  Consequences  the Buyers may
suffer  through and after the date of the claim for  indemnification  (including
any Adverse  Consequences  the Buyers may suffer after the end of any applicable
survival period)  resulting from,  arising out of, relating to, or caused by the
breach (or the  alleged  breach) of such  Sellers'  representations,  warranties
and/or covenants contained herein.

     (c) INDEMNIFICATION PROVISIONS FOR BENEFIT OF THE SELLERS. In the event the
Buyers breach any of their representations,  warranties, and covenants contained
herein,  and,  if there is an  applicable  survival  period  pursuant to ss.7(a)
above,   provided   that  any  of  the  Sellers   makes  a  written   claim  for
indemnification  against  the Buyers  pursuant  to  ss.11(h)  below  within such
survival period, then the Buyers agree to indemnify each of the Sellers from and
against the entirety of any Adverse  Consequences the Sellers may suffer through
and  after  the date of the claim for  indemnification  (including  any  Adverse
Consequences  the Sellers may suffer  after the end of any  applicable  survival
period) resulting from, arising out of, relating to, in the nature of, or caused
by the breach (or the alleged breach).

     (d) MATTERS INVOLVING THIRD PARTIES.

          (i) If any  third  party  shall  notify  any Party  (the  "INDEMNIFIED
     PARTY") with respect to any matter (a "THIRD PARTY  CLAIM")  which may give
     rise  to  a  claim  for  indemnification   against  any  other  Party  (the
     "INDEMNIFYING  PARTY") under this ss.7,  then the  Indemnified  Party shall
     promptly  notify each  Indemnifying  Party  thereof in  writing;  PROVIDED,
     HOWEVER,  that no delay on the part of the  Indemnified  Party in notifying
     any  Indemnifying  Party  shall  relieve  the  Indemnifying  Party from any
     obligation   hereunder   unless   (and  then  solely  to  the  extent)  the
     Indemnifying Party thereby is prejudiced.

          (ii) Any  Indemnifying  Party  will  have  the  right  to  defend  the
     Indemnified  Party against the Third Party Claim with counsel of its choice
     reasonably  satisfactory  to the  Indemnified  Party  so  long  as (A)  the
     Indemnifying Party notifies the Indemnified Party in writing within fifteen
     (15) days after the Indemnified Party has given written notice of the Third
     Party Claim that the  Indemnifying  Party will  indemnify  the  Indemnified
     Party  from and  against  the  entirety  of any  Adverse  Consequences  the
     Indemnified  Party may suffer resulting from,  arising out of, relating to,
     in the nature of, or caused by the Third Party Claim,  (B) the Indemnifying
     Party provides the Indemnified Party with evidence reasonably acceptable to
     the Indemnified  Party that the Indemnifying  Party will have the financial
     resources  to  defend  against  the  Third  Party  Claim  and  fulfill  its
     indemnification  obligations hereunder,  (C) the Third Party Claim involves
     only  money  damages  and does not seek an  injunction  or other  equitable
     relief,  (D)  settlement  of, or an adverse  judgment  with respect to, the
     Third  Party Claim is not,  in the good faith  judgment of the  Indemnified
     Party,  likely to establish a  precedential  custom or practice  materially
     adverse to the continuing  business interests of the Indemnified Party, and
     (E) the  Indemnifying  Party  conducts the defense of the Third Party Claim
     actively and diligently.

                                      -22-
<PAGE>
          (iii) So long as the  Indemnifying  Party is conducting the defense of
     the  Third  Party  Claim in  accordance  with  ss.7(d)(ii)  above,  (A) the
     Indemnified  Party  may  retain  separate  co-counsel  at its sole cost and
     expense and  participate  in the defense of the Third Party Claim,  (B) the
     Indemnified  Party will not  consent to the entry of any  judgment or enter
     into any  settlement  or  compromise  with respect to the Third Party Claim
     without  the prior  written  consent of the  Indemnifying  Party (not to be
     withheld unreasonably),  and (C) the Indemnifying Party will not consent to
     the entry of any judgment or enter into any  settlement or compromise  with
     respect to the Third Party Claim without the prior  written  consent of the
     Indemnified Party (not to be withheld unreasonably).

          (iv) In the event any of the  conditions  in  ss.7(d)(ii)  above is or
     becomes unsatisfied, however, (A) the Indemnified Party may defend against,
     and consent to the entry of any judgment or enter into any settlement  with
     respect  to, the Third  Party  Claim in any manner it  reasonably  may deem
     appropriate (and the Indemnified Party need not consult with, or obtain any
     consent from,  any  Indemnifying  Party in connection  therewith),  (B) the
     Indemnifying  Parties will  reimburse the  Indemnified  Party  promptly and
     periodically  for the costs of  defending  against  the Third  Party  Claim
     (including   reasonable   attorneys'  fees  and  expenses),   and  (C)  the
     Indemnifying  Parties will remain responsible for any Adverse  Consequences
     the Indemnified  Party may suffer resulting from,  arising out of, relating
     to, in the nature  of, or caused by the Third  Party  Claim to the  fullest
     extent provided in this ss.7.

     (e) DETERMINATION OF ADVERSE  CONSEQUENCES.  All  indemnification  payments
under this ss.7 by Flowers  shall reduce the  Purchase  Price dollar for dollar,
which such  reduction  shall be applied  proportionately  to the Purchase  Price
received by each of the Sellers.

     (f) SET-OFF  AGAINST THE BUYERS  NOTES.  Notwithstanding  that only Flowers
shall be liable to indemnify the Buyers in the manner contemplated hereunder, to
the extent that the Buyers are entitled to any Adverse  Consequences  hereunder,
each of the Sellers agrees that the Buyers shall have the right,  subject to the
terms of this paragraph,  to set-off,  as against the Buyers Notes any claim for
indemnification  against  Flowers  hereunder,  provided  that either (a) Flowers
shall have  consented  in  writing to any such  set-off or (b) the amount of any
such indemnification claim has been determined in a final judgment of a court of
competent  jurisdiction  after all appeal rights have expired.  Any such set-off
shall reduce the principal  amount then  outstanding  under such Buyers Notes to
the extent of such set-off.

     (g)  LIMITATIONS  ON  INDEMNIFICATION.  Either or both Buyers shall make no
claims  for  indemnification  against  Flowers  under this  Agreement  until the
aggregate of any Adverse Consequences suffered, individually or collectively, by
such Buyers, as the case may be, exceeds $75,000.00.  Upon reaching such amount,
such Buyer or Buyers,  as the case may be, shall be entitled to  indemnification
from Flowers for all such amounts exceeding such $75,000.00. Notwithstanding any
other  provision  to  the  contrary  contained  in  this  Agreement  or  in  any
certificate or instrument delivered hereunder,  the Buyers, whether individually
or collectively, shall not be entitled to claim indemnification from Flowers for

                                      -23-
<PAGE>
any   amounts   in  excess  of  One   Million   Dollars   ($1,000,000.00).   Any
indemnification  to which  either or both Buyers  shall be entitled to hereunder
shall be reduced by (a) any tax benefits accruing to any of the Buyers, directly
or  indirectly,  as a  result  of such  indemnity  and (b) any  proceeds  of any
insurance   policy   payable  in  respect  of  the  matter   relating   to  such
indemnification.  No Party shall be entitled to any  indemnification  of matters
related,  directly  or  indirectly,  to such  Party's  fraud,  bad faith,  gross
negligence or misconduct.

     (h)  OTHER  INDEMNIFICATION   PROVISIONS.   The  foregoing  indemnification
provisions  are in  addition  to,  and  not in  derogation  of,  any  statutory,
equitable,  or common law remedy (including  without  limitation any such remedy
arising under environmental, health, and safety requirements) any Party may have
with respect to Protocol,  or the  transactions  contemplated by this Agreement.
The parties hereto confirm that,  notwithstanding  any other provision contained
herein or in any document delivered  hereunder,  neither Protocol nor the Buyers
shall have any claims for any Adverse  Consequences or otherwise  against any of
the  Sellers  other  than  Flowers  and that all  limitations  and  restrictions
applicable  to any claims for  indemnfication  by the Buyers from Flowers  under
this Section (including, without limitation, Section 7(a) and 7(g) shall equally
limit or restrict any claims for any Adverse  Consequences  or otherwise made by
either the Buyers or Protocol against Flowers under this Section 7(h).

Each of the  Sellers  hereby  agrees  that he or it will not make any  claim for
indemnification  against  Protocol  by  reason  of the fact  that he or it was a
former director,  former officer,  former employee,  or former agent of Protocol
(whether such claim is for judgments,  damages, penalties, fines, costs, amounts
paid in  settlement,  losses,  expenses,  or otherwise and whether such claim is
pursuant to any statute, charter document,  bylaw, agreement, or otherwise) with
respect to any action, suit, proceeding,  complaint, claim, or demand brought by
the  Buyers  against  such  Sellers  (whether  such  action,  suit,  proceeding,
complaint,  claim, or demand is pursuant to this  Agreement,  applicable law, or
otherwise).  The parties  confirm that the foregoing shall not apply to restrict
or limit the right of Flowers to maintain any claim against  Protocol  following
the Closing Date as a current director, officer and/or employee of Protocol.

     8. TAX MATTERS.  The following  provisions  shall govern the  allocation of
responsibility  as between  the Buyers  and  Flowers  for  certain  tax  matters
following the Closing Date:

     (a) TAX PERIODS  ENDING ON OR BEFORE THE  CLOSING  DATE.  The Buyers  shall
prepare  or cause to be  prepared  and file or cause to be filed  following  the
Closing Date all Tax Returns for Protocol for all periods  ending on or prior to
the Closing Date. The Buyers shall permit Protocol to review and comment on each
such Tax Return  described in the  preceding  sentence  prior to filing of same.
Flowers  shall  reimburse  the Buyers for any Taxes of Protocol  with respect to
such periods  within  sixty (60)  calendar  days after  payment by the Buyers or
Protocol of such Taxes to the extent such Taxes are not reflected in the reserve
for Tax liabilities  (rather than any reserve for deferred Taxes  established to
reflect timing differences between book and Tax income) shown on the face of the
Most Recent Financial Statements.  Flowers shall have no obligation to reimburse
the  Buyers  and/or  Protocol,  as the  case  may  be,  in  respect  of any  tax
liabilities  as the result of any  re-filing by Buyers,  at their  election,  of
previous years' tax returns.

                                      -24-
<PAGE>
     (b) COOPERATION ON TAX MATTERS.

          (i) The Buyers, Protocol and the Sellers shall cooperate fully, as and
     to the extent reasonably requested by the other Parties, in connection with
     the  filing  of Tax  Returns  pursuant  to  this  Section  and  any  audit,
     litigation  or other  proceeding  with respect to Taxes.  Such  cooperation
     shall  include  the  retention  and (upon the other  party's  request)  the
     provision of records and information  which are reasonably  relevant to any
     such audit, litigation or other proceeding and making employees of Protocol
     available on a mutually convenient basis to provide additional  information
     and  explanation  of any  material  provided  hereunder.  Protocol  and the
     Sellers  agree (A) to retain  all books and  records  with  respect  to Tax
     matters  pertinent  to Protocol  relating to any taxable  period  beginning
     before the Closing Date until the  expiration of the statute of limitations
     (and, to the extent  notified by the Buyers or the Sellers,  any extensions
     thereof)  of the  respective  taxable  periods,  and to abide by all record
     retention  agreements  entered into with any taxing  authority,  and (B) to
     give the other  party  reasonable  written  notice  prior to  transferring,
     destroying or discarding any such books and records and, if the other party
     so reasonably requests,  Protocol or the Sellers, as the case may be, shall
     allow the other party to take possession of such books and records.

          (ii) The Buyers and the Sellers  further agree,  upon request,  to use
     their  reasonable  best efforts to obtain any certificate or other document
     from any governmental  authority or any other Person as may be necessary to
     mitigate, reduce or eliminate any Tax that could be imposed (including, but
     not limited to, with respect to the transactions contemplated hereby).

          (iii) The Buyers and the  Sellers  further  agree,  upon  request,  to
     provide  the other  party with all  information  that  either  party may be
     required to report  pursuant to Section  6043 of the Code and all  Treasury
     Department Regulations promulgated thereunder.

     (c)  TAX  SHARING  AGREEMENTS.   All  tax  sharing  agreements  or  similar
agreements  with respect to or involving  Protocol shall be terminated as of the
Closing Date and, after the Closing Date, Protocol shall not be bound thereby or
have any liability thereunder.

     (d)  CERTAIN  TAXES.  All  transfer,   documentary,   sales,   use,  stamp,
registration  and  other  such  Taxes  and fees  (including  any  penalties  and
interest)  incurred  in  connection  with this  Agreement  eligible  against the
Sellers in connection  with the  disposition of their  Protocol  Shares shall be
paid by the Sellers when due, and the Sellers will,  at their own expense,  file
all  necessary  Tax Returns  and other  documentation  with  respect to all such
transfer, documentary, sales, use, stamp, registration and other Taxes and fees,
and,  if  required  by  applicable  law,  the  Buyers  will,  and will cause its
affiliates  to,  join  in the  execution  of any  such  Tax  Returns  and  other
documentation.

     9. TERMINATION.

     (a)  TERMINATION  OF AGREEMENT.  Certain of the Parties may terminate  this
Agreement as provided below:

     written consent at any time prior to the Closing;

          (ii) The Buyers may terminate  this Agreement by giving written notice
     to the Sellers at any time prior to the Closing (A) in the event any of the
     Sellers  (subject  to the right of the  Sellers  to update  the  Disclosure
     Schedule  prior to  Closing)  has  breached  any  material  representation,
     warranty,  or covenant  contained in this Agreement in any material respect
     and the Buyers has notified the Sellers of such breach,  and the breach has
     continued  without cure for a period of thirty (30) calendar days after the
     notice of such breach or (B) if the Closing  shall not have  occurred on or
     before  September  30,  2000,  by reason of the  failure  of any  condition
     precedent under ss.6(a) hereof (unless the failure  results  primarily from
     the Buyers breach of any representation, warranty, or covenant contained in
     this Agreement); and

          (iii) The Sellers  may  terminate  this  Agreement  by giving  written
     notice to the Buyers at any time prior to the  Closing (A) in the event the
     Buyers have  breached any material  representation,  warranty,  or covenant
     contained in this Agreement in any material  respect and any of the Sellers
     has  notified  the Buyers of such  breach,  and the  breach  has  continued
     without cure for a period of thirty (30)  calendar days after the notice of
     such  breach or (B) if the  Closing  shall not have  occurred  on or before
     September  30, 2000,  by reason of the failure of any  condition  precedent
     under ss.6(b) hereof (unless the failure results  primarily from any of the
     Sellers breach of any  representation,  warranty,  or covenant contained in
     this Agreement).

     (b) EFFECT OF TERMINATION.  If any Party terminates this Agreement pursuant
to ss.9(a)  above,  all rights and  obligations of the Parties  hereunder  shall
terminate  without any liability of any Party to any other Party except that the
Buyers'  confidentiality  obligations  set forth in  Section  5(d)  above  shall
survive the termination of this Agreement.

     10. MISCELLANEOUS.

     (a) NATURE OF CERTAIN OBLIGATIONS.

          (i)  COVENANTS.  The covenants of each of the Sellers in ss.2(a) above
     concerning  the sale of his or its  Protocol  Shares to the  Buyers and the
     representations  and  warranties  of each of the  Sellers in ss.3(a)  above
     concerning the transaction are several obligations.

          (ii) OTHER MATTERS. The remainder of the representations,  warranties,
     and  covenants in this  Agreement are joint and several  obligations.  This
     means that each Sellers will be responsible to the extent  provided in ss.7
     above,  and subject to the limitations  contained  herein,  for any Adverse
     Consequences the Buyers may suffer as a result of any breach thereof.

     (b) PRESS RELEASES AND PUBLIC ANNOUNCEMENTS. No Party shall issue any press
release or make any public  announcement  relating to the subject matter of this
Agreement  without the prior  written  approval  of the Buyers and the  Sellers;

                                      -26-
<PAGE>
disclosure  to the other  parties of the form of such public  announcement,  any
public disclosure it believes in good faith is required by applicable law or any
listing or trading agreement concerning its publicly-traded securities (in which
case the  disclosing  Party will use its  reasonable  best efforts to advise the
other Parties prior to making the disclosure).

     (c) NO  THIRD-PARTY  BENEFICIARIES.  This  Agreement  shall not  confer any
rights or remedies  upon any Person other than the Parties and their  respective
successors and permitted assigns.

     (d) ENTIRE AGREEMENT.  This Agreement  (including the documents referred to
herein)  constitutes  the entire  agreement among the Parties and supersedes any
prior  understandings,  agreements,  or representations by or among the Parties,

hereof,  including,  without  limitation,  all letters of intent or memoranda of
understanding executed by the parties hereto prior to the date hereof.

inure to the benefit of the Parties named herein and their respective successors
and permitted  assigns.  No Party may assign either this Agreement or any of his
or its rights,  interests,  or obligations  hereunder  without the prior written
approval of the Buyers and the Sellers,  PROVIDED,  HOWEVER, that the Buyers may
(i) assign any or all of its rights and  interests  hereunder  to one or more of
its  Affiliates  and (ii) designate one or more of its Affiliates to perform its
obligations hereunder (in any or all of which cases the Buyers nonetheless shall

subject matter  (regardless  of the relative  levels of  specificity)  which the
Party has not  breached  shall not detract  from or  mitigate  the fact that the
Party is in breach of the first representation, warranty, or covenant.
