     FOR VALUE  RECEIVED,  the undersigned  ("Borrower")  promises to pay to the
order of CAPITAL BANK, a Florida banking corporation  ("Bank"), at the office of
the Bank at 1221 Brickell Avenue, Miami, Florida 33131 or at such other place as
the holder hereof may from time to time designate in writing,  the principal sum
of ONE  MILLION  AND NO/100  DOLLARS  ($1,000,000.00),  together  with  interest
thereon on the principal  amount from time to time outstanding at an annual rate
prior to maturity or default of one and  one-quarter  percent  (1-1/4%) over the
"Prime Rate" (Prime Rate shall mean, at any time, the rate of interest quoted in
the Wall Street  Journal,  Money Rates  Section as the "Prime  Rate"  (currently
defined  as the base  rate on  corporate  loans  posted  by at least  75% of the
nation's thirty (30) largest banks),  with the Prime Rate in effect on the first
day of a month being  applicable to the entire month. In the event that the Wall
Street Journal quotes more than one rate, or a range of rates as the Prime Rate,
then the Prime  Rate shall mean the  average of the quoted  rates.  In the event
that the Wall Street Journal ceases to publish a Prime Rate, then the Prime Rate
shall be the average of the three largest U.S. money center commercial banks, as
determined  by Bank).  Interest  shall be computed on the actual  number of days
elapsed and an assumed year of 360 days.  Borrower and all endorsers,  sureties,
guarantors  and any other persons liable or to become liable with respect to the
loan  evidenced  by this  Note  (the  "Loan")  are  each  included  in the  term
"Obligors" as used in this Note. Said principal and interest shall be payable in
lawful  money of the United  States,  on the dates and in the amounts  specified
below, to wit:

      (a)   Interest  on the  outstanding  principal  balance  shall  be paid in
      monthly  installments  commencing  on the  first  (1st)  day of the  month
      following  the date  hereof,  and on the  first  (1st)  day of each  month
      thereafter.

      (b)   The  then-outstanding  principal balance plus any accrued and unpaid
      interest shall be due and payable ON DEMAND ("Maturity Date").

      Borrower  shall  pay to Bank a late  charge  of five  percent  (5%) of any
payment not received by Bank within fifteen (15) days of its due date; provided,
however, if said fifteen (15) day period ends on a day other than a day on which
Bank is open for  Business (a  "Business  Day"),  then the  aforedescribed  late
charge shall be payable if the payment is not received by the last  Business Day
within said fifteen (15) day period.

      This Note may be prepaid in whole or in part at any time without penalty.

      Borrower  shall pay all  amounts  owing  under  this Note in full when due
without   set-off,   counterclaim   deduction  or  withholding  for  any  reason
whatsoever.  If any payment  falls due on a day other than a Business  Day, then
such payment  shall  instead be made on the next  succeeding  Business  Day, and
interest shall accrue accordingly.  Any payment received by Bank after 1:00 p.m.
shall not be credited  against the  indebtedness  under this Note until at least
the next succeeding Business Day.






                                      1






      If default  be made in the  payment of any sums  payable  pursuant  to the
terms of this Note,  or if default or other event  causing the  acceleration  of
this Note occur under the Loan Agreement  between  Borrower and Bank dated April
10, 1997, as amended by the First  Amendment to Loan  Agreement  dated even date
herewith (the "Loan  Agreement") or under the Security  Agreement  securing this
Note between Borrower, Aquagenix, Inc. and Bank dated April 10, 1997, as amended
by the First  Amendment  to Security  Agreement  dated even date  herewith  (the
"Security Agreement"),  the Continuing Guaranty by Aquagenix, Inc. ("Guarantor")
dated April 10, 1997, as reaffirmed by Reaffirmation of Guaranty dated even date
herewith ("Guaranty"), the Promissory Note in the amount of $250,000 dated April
10, 1997,  executed by Guarantor (the "Term Note"), the Consolidated  Promissory
Note in the  amount of  $1,000,000  between  Borrower  and Bank  dated even date
herewith (the  "Consolidated  Note"),  the Term Promissory Note in the amount of
$200,000  between Borrower and Bank dated even date herewith (the "$200,000 Term
Note"),  the Guidance  Equipment Line  Promissory Note in the amount of $270,000
between  Borrower and Bank dated even date  herewith  ("Equipment  Note") or any
other  instrument or document  executed in connection  with the Loan (this Note,
the Loan Agreement,  the Security  Agreement,  the Guaranty,  the Term Note, the
Consolidated  Note,  the $200,000  Term Note,  the  Equipment  Note and all such
instruments  and  documents,  including,  without  limitation,  any  guaranties,
agreements,  UCC-1 financing  statements,  security agreements,  assignments and
other  documents  securing this Note,  are referred to in this Note as the "Loan
Documents")  (an  "Event of  Default"),  then or at any time  thereafter  at the
option of Bank, the whole of the principal sum then remaining unpaid  hereunder,
together  with all interest  accrued  thereon and all other sums owing under the
Loan Documents, shall immediately become due and payable without notice and Bank
shall be  entitled  to  pursue  any and all  rights  and  remedies  provided  by
applicable  law and/or under the terms of this Note or any other Loan  Document,
all  of  which  shall  be  cumulative  and  may  be  exercised  successively  or
concurrently.  The foregoing  references shall not be deemed to limit the demand
feature of this Note.  Upon the  occurrence and during the  continuation  of any
Event of Default,  Bank, at its option, may at any time declare any or all other
liabilities of any Obligor to Bank immediately due and payable  (notwithstanding
any  contrary  provisions  thereof)  without  demand or  notice of any kind.  In
addition,  Bank  shall  have the  right to set off any and all sums  owed to any
Obligor  by Bank in any  capacity  (whether  or not then due)  against  the Loan
and/or against any other liabilities of any Obligor to Bank.

      From and after an Event of  Default,  and  regardless  of whether the Bank
also  elects to  accelerate  the  maturity  of this Note,  the entire  principal
remaining unpaid hereunder shall bear an augmented annual interest rate equal to
the  lesser  of (i)  eighteen  percent  (18%)  per  annum,  or (ii) the  highest
applicable lawful rate.  Failure to exercise any and all rights or remedies Bank
may in the event of any such  default  be  entitled  to shall not  constitute  a
waiver of the right to  exercise  such  rights or  remedies  in the event of any
subsequent  default,  whether of the same or different  nature. No waiver of any
right or remedy by Bank shall be effective  unless made in writing and signed by
Bank, nor shall any waiver on one occasion apply to any future occasion.

      In no event shall any agreed or actual exaction charged, reserved or taken
as an advance or  forbearance by Bank as  consideration  for the Loan exceed the
limits (if any) imposed or provided by the law  applicable  from time to time to
the Loan for the use or  detention  of money or for  forbearance  in seeking its
collection, and Bank hereby waives any right to demand such excess. 










                                      2





If the floating rate of interest  based on the Prime Rate should  increase above
such  maximum   interest  rate  permitted  by  applicable  law  (if  any),  then
notwithstanding  any contrary  provision in this Note or any other Loan Document
and without necessity of further agreement or notice by Bank or any Obligor, the
unpaid  principal  balance of the Loan shall  thereupon  bear  interest  at such
maximum lawful rate. If the floating interest should  thereafter  decrease below
such maximum lawful rate, the Loan shall nevertheless  continue to bear interest
at such  maximum  lawful rate until Bank,  receives  the full amount of interest
delayed by the application of such maximum lawful rate under this paragraph,  at
which  time the Loan  shall once  again  bear  interest  at the then  applicable
floating  interest rate. In the event that the interest  provisions of this Note
or any  exactions  provided  for in this Note or any other Loan  Document  shall
result  at any time or for any  reason in an  effective  rate of  interest  that
transcends the maximum  interest rate permitted by applicable law (if any), then
without  further  agreement or notice the  obligation  to be fulfilled  shall be
automatically  reduced to such limit and all sums  received by Bank in excess of
those lawfully collectible as interest shall be applied against the principal of
the Loan immediately upon Bank's receipt thereof, with the same force and effect
as though the payor had specifically designated such extra sums to be so applied
to  principal  and  Bank  had  agreed  to  accept  such  extra  payment(s)  as a
premium-free  prepayment  or  prepayments.  During  any time that the Loan bears
interest at the maximum lawful rate (whether by  application of this  paragraph,
the default provisions of this Note or otherwise), interest shall be computed on
the basis of the actual  number of days elapsed and the actual number of days in
the respective calendar year. The interest rate charged is authorized by Florida
Statutes, Chapter 665.

      The Obligors hereby  severally:  (a) waive demand,  presentment,  protest,
notice of dishonor,  suit against or joinder of any other person,  and all other
requirements  necessary to charge or hold any Obligor liable with respect to the
Loan;  (b) waive any right to immunity  from any such action or  proceeding  and
waive  any  immunity  or  exemption  of any  property,  wherever  located,  from
garnishment,  levy, execution, seizure or attachment prior to or in execution of
judgment,  or sale under execution or other process for the collection of debts;
(c) waive any right to interpose any set-off or  non-compulsory  counterclaim or
to plead laches or any statute of limitations as a defense in any such action or
proceeding  and waive (to the  extent  lawfully  waivable)  all  provisions  and
requirements  of law for the benefit of any Obligor now or  hereafter  in force;
(d) submit to the  jurisdiction  of the state and federal courts in the State of
Florida for purposes of any such action or proceeding;  (e) agree that the venue
of any  such  action  or  proceeding  may be laid in Dade  County,  Florida  (in
addition to any county in which any  collateral  for the Loan is  located),  and
waive any claim  that the same is an  inconvenient  forum;  (f)  stipulate  that
service of process in any such action or  proceeding  shall be properly  made if
mailed by any form of registered or certified  mail (airmail if  international),
postage  prepaid,  to the  address  then  registered  in Bank's  records for the
Obligor(s) so served, and that any process so served shall be effective ten (10)
days  after  mailing;  and (g)  agree  that the  death  or  mental  or  physical
incapacity of any Obligor that is a natural person, or the dissolution or merger
or  consolidation  or  termination  of the  existence  of any Obligor  that is a
business entity (or if any person controlling such Obligor shall take any action
authorizing or leading to the same), shall at Bank's option, which option may be
exercised then or at any time thereafter,  result in the Loan being then due and
payable in full.  No  provision  of this Note shall limit  Bank's right to serve
legal  process in any other manner  permitted by law or to bring any such action
or proceeding in any other competent jurisdiction. The Obligors hereby severally
consent and agree that,  at any time and from time to time without  notice,  (i)












                                      3




Bank and the  owners(s) of any  collateral  then  securing the Loan may agree to
release,  increase,  change,  substitute  or  exchange  all or any  part of such
collateral,  and (ii) Bank and any person(s) then primarily  liable for the Loan
may agree to  renew,  extend  or  compromise  the Loan in whole or in part or to
modify  the  terms  of the  Loan in any  respect  whatsoever;  no such  release,
increase, change,  substitution,  exchange,  renewal,  extension,  compromise or
modification  shall  release or affect in any way the  liability of any Obligor,
and  the  Obligors  hereby  severally  waive  any and all  defenses  and  claims
whatsoever  based thereon.  Until Bank receives all sums due under this Note and
all other Loan Documents in  immediately  available  funds,  no Obligor shall be
released from liability with respect to the Loan unless Bank expressly  releases
such Obligor in a writing  signed by Bank,  and Bank's release of any Obligor(s)
shall not release any other person liable with respect to the Loan.

      The  Obligors  jointly  and  severally  agree to pay all  filing  fees and
similar  charges  and all costs  incurred by Bank in  collecting  or securing or
attempting to collect or secure the Loan, including reasonable  attorney's fees,
whether  or  not  involving  litigation  and/or  appellate,   administrative  or
Bankruptcy  proceedings.  The Obligors  jointly and  severally  agree to pay any
documentary stamp taxes, intangibles taxes or other taxes (except for federal or
Florida  franchise or income taxes based on Bank's net income)  which may now or
hereafter  apply to this  Note or the  Loan or any  security  therefor,  and the
Obligors  jointly and  severally  agree to indemnify and hold Bank harmless from
and  against  any  liability,  costs,  reasonable  attorney's  fees,  penalties,
interest  or expenses  relating  to any such taxes,  as and when the same may be
incurred.  The Obligors  jointly and  severally  agree to pay on demand,  and to
indemnify and hold Bank harmless from and against, any and all present or future
taxes (other than income tax of Bank), levies, imposts, deductions,  charges and
withholdings  imposed in  connection  with the Loan by the laws or  governmental
authorities  of any  jurisdiction  other than the State of Florida or the United
States of America,  and all  payments to Bank under this Note shall be made free
and clear thereof and without deduction therefor.

      This Note shall be governed by, and  construed  and enforced in accordance
with, the laws of the State of Florida,  except that federal law shall govern to
the extent that it may permit Bank to charge, from time to time, interest on the
Loan at a rate higher than may be permissible under applicable Florida law.

      Any  provision of this Note which is prohibited  or  unenforceable  in any
jurisdiction  shall, as to such  jurisdiction  only, be ineffective  only to the
extent  of  such  prohibition  or  unenforceability   without  invalidating  the
remaining  provisions hereof or affecting the validity or enforceability of such
provision  in any  other  jurisdiction.  To the  extent  that the  Obligors  may
lawfully  waive any law that would  otherwise  invalidate  any provision of this
Note,  each of them hereby  waives the same,  to the end that this Note shall be
valid and binding and  enforceable  against each of them in accordance  with all
its terms.

      If this Note is signed by more than one person,  then the term  "Borrower"
as used in this Note shall refer to all such persons jointly and severally,  and
all  promises,   agreements,   covenants  waivers,  consents,   representations,
warranties  and other  provisions  in this Note are made by and shall be binding
upon each and every undersigned person,  jointly and severally.  The term "Bank"
shall be deemed to include any subsequent  holder(s) of this Note. Whenever used










                                      4





in this Note, the term "person" means any individual,  firm, corporation,  trust
or other  organization or association or other enterprise or any governmental or
political subdivision,  agency,  department or instrumentality thereof. Whenever
used in this Note, words in the singular include the plural, words in the plural
include the singular,  and pronouns of any gender include the other genders, all
as may be  appropriate.  The "Prime Rate" is a base  reference  rate of interest
adopted  by  Capital  Bank  as a  general  benchmark  from  which  Capital  Bank
determines the floating  interest rates chargeable on various loans to borrowers
with varying degrees of creditworthiness,  and Borrower  acknowledges and agrees
that Bank has made no  representations  whatsoever  that the "Prime Rate" is the
interest  rate actually  offered by Capital Bank to borrowers of any  particular
creditworthiness.

      Time shall be of the essence with respect to the terms of this Note.  This
Note  cannot  be  changed  or  modified  orally.   Bank  shall  have  the  right
unilaterally  to correct  patent  errors or  omissions in this Note or any other
Loan Document.  Except as otherwise required by law or by the provisions of this
Note or any other Loan Document,  payments  received by Bank hereunder  shall be
applied first against expenses and indemnities, next against interest accrued on
the Loan,  and next in reduction  of the  outstanding  principal  balance of the
Loan,  except  that from and after any default  under this Note,  Bank may apply
such  payments  in any order of  priority  determined  by Bank in its  exclusive
judgment.  Borrower shall receive  immediate  credit on payments only if made in
the form of either a federal wire  transfer of cleared funds or a check drawn on
an  account  maintained  with  Bank  containing   sufficient   available  funds.
Otherwise,  Borrower  shall receive credit on payments  after  clearance,  which
shall be no sooner than the first Business Day after receipt of payment by Bank.
For purposes of determining  interest accruing under this Note,  principal shall
be deemed  outstanding  on the date payment is credited by Bank.  If any payment
required to be made pursuant to this Note is not received on the due date,  Bank
shall have the right, at its election,  to charge any of Borrower's  accounts at
Bank  with the  amount of such  payment.  Except as  otherwise  required  by the
provisions of this Note or any other Loan  Document,  any notice  required to be
given to any Obligor shall be deemed sufficient if made personally or if mailed,
postage  prepaid,  to such Obligor's  address as it appears in this Note (or, if
none  appears,  to any  address  for such  Obligor  then  registered  in  Bank's
records). Bank may grant participations in all or any portion of, and may assign
all or any part of Bank's rights under, this Note. Bank may disclose to any such
participant or assignee any and all information  held by or known to Bank at any
time  with  respect  to any  Obligor.  If  Borrower  or any other  Obligor  is a
partnership,  then all  general  partners  thereof  shall be liable  jointly and
severally  for all  obligations  under  this Note and for all  other  covenants,
agreements,  undertakings  and  obligations  of Borrower in connection  with the
Loan,  notwithstanding  any contrary  provision of the  partnership  laws of the
State of  Florida.  All of the terms of this Note shall  inure to the benefit of
Bank and its successors and assigns and shall be binding upon each and every one
of the Obligors and their respective heirs, executors, administrators,  personal
representatives, successors and assigns, jointly and severally.

      This Consolidated  Promissory Note  consolidates  that certain  Promissory
Note executed by Borrower in favor of Bank dated April 10, 1997, in the original
principal sum of Seven  Hundred  Fifty  Thousand  Dollars  ($750,000),  and that
certain  Future  Advance  Promissory  Note dated of even date  herewith,  in the
original principal sum of Two Hundred Fifty Thousand Dollars ($250,000).
