Item 5.  Other Events

     Effective December 29, 1997, the Company refinanced its revolving line
of credit with Barnett Bank, N.A. (the "Bank").  The original revolving line 
of credit was obtained in February, 1996 for $2,000,000 and extended to 
$2,500,000 in July, 1997 by a First Amendment to Loan and Security Agree-
ment, Loan Agreement, and Security Agreement.  The refinanced revolving 
loan agreement has a maturity date of May 1, 2000, as opposed to the prior 
lines which were on demand, and is for an amount of up to $1,600,000 and 
bears interest at the Bank's prime rate.

     The Company also obtained a five year term loan of $1,500,000 due 
December 29, 2002 at an annual interest rate of 8.60%.  The interest was 
fixed based upon a variable rate note (LIBOR plus 2.25% floating rate) and 
an interest rate swap agreement entered into with the Bank.  The swap 
agreement in effect reduces the interest rate risk by allowing the Company 
to lock-in a fixed rate by converting the foregoing variable rate obliga-
tion.  The term loan is payable in equal principal payments of $25,000 
plus interest. Early termination of the swap agreement, either through 
prepayment or default on the term loan, may result in a cost or a benefit
to the Company.  The market risk from such early termination that arises 
from the movement in interest rates may cause a liability to the Company 
if interest rates are down, and a benefit to the Company if interest rates 
are up, with the Company recognizing a loss or gain resulting from the 
difference between its fixed interest rate and the market value of 
interest rates at the time of early termination.  Under the term loan, 
the Company is obligated to adhere to a variety of affirmative and 
negative covenants, including but not limited to a debt service ratio of 
1:25 to 1:00, a current ratio of 1:5 to 1:00, a capital funds ratio of 
total debt to capital funds of no more than 1:7 to 1:00, maintenance of 
capital funds equal to or in excess of $3,500,000, and the Company may not 
sell any of its assets or properties, except inventory in the ordinary 
course of business, within any calendar year for which the aggregate book 
value exceeds $500,000.  The term loan also provides for restrictions on 
transactions with related persons, precludes changes in ownership in the 
Company which would reduce the ownership by its parent, Medicore, Inc. 
(the "Parent") to less than 51%, and restricts the Company from engaging 
in any new unrelated business which might adversely affect the repayment 
of the term loan.

     Both the revolving and term financing facilities are secured by a first 
security interest on corporate assets, have cross-default provisions and 
are unconditionally guaranteed by the Parent.  The Parent has also subordin-
ated $2,291,665 in principal indebtedness due to it from the Company to 
these financing facilities, provided the Company may make payments to its 
Parent on the subordinated debt from additional equity that is injected 
into the Company or from the use, on a quarterly basis, of retained 
earnings arising subsequent to March 31, 1995, so long as the Company is 
otherwise in full compliance with all financial covenants of the loan 
agreements.

     The Company also has two other commercial term loans from the Bank 
obtained in February, 1996.  One is a five-year term loan of $712,500 
expiring February 7, 2001 at an annual rate of interest of 8.28% with 
monthly payments of principal and interest of $6,925 based on a 15-year 
amortization schedule with the unpaid principal and accrued interest due 
on the expiration date.  This loan is secured by a mortgage on properties 
in Hialeah, Florida owned by the Parent, two of which are leased to the 
Company and one parcel being vacant land used as a parking lot.  The 
Parent has assigned the leases and rents to the Bank as further security 
for that term loan, 

<PAGE>

provided the Parent may continue to collect the rents until an event of 
default, if any.  The Parent has also subordinated its interests in the 
leases to the mortgage held by the Bank.

     The second commercial term loan obtained from the Bank in February, 
1996 was for the principal amount of $200,000 for a period of five years 
bearing interest at a per annum rate of 1.25% over the Bank's prime rate 
and requiring monthly principal payments of $3,333 plus accrued interest
through expiration on February 7, 2001.  This $200,000 term loan carries 
no prepayment penalty and is secured by all of the Company's tangible per-
sonal property, goods and equipment, and all cash or non-cash proceeds of 
such collateral.  The Parent has also unconditionally guaranteed the 
payment and performance by the Company of these two term loans.

     2.   Definitions.
          -----------

          (a)  Except as otherwise expressly provided herein, all capi-
talized terms used in this Amendment shall have the meanings set forth in 
the Agreement.

          (b)  The definitions of the following terms contained in Section 
1.1 of the Agreement are hereby modified and amended, in their entirety, 
to read respectively as set forth below:

               "Borrowing Base" shall mean on any date the sum 
          of (i) seventy-five percent (75%) of the face amount 
          of Eligible Accounts on such date, plus (ii) the lesser 
          of (a) twenty percent (20%) of Eligible U.S. Inventory 
          or (b) $600,000.00.

               "Capital Funds" shall mean the "tangible net

          as the same may be amended from time to time hereafter.

<PAGE>

          (c)  Section 1.1 of the Security Agreement is hereby modified 
and amended to add the following definition thereto:

               "Eligible U.S. Inventory" shall mean the value, 
          determined in accordance with GAAP, of Inventory 
          consisting of raw materials and finished goods located
          in the United States which the Lender, in its sole 
          discretion, deems to be Eligible U.S. Inventory, ex-
          cluding, however, (i) the amount of progress payments,
          predelivery payments, deposits and any other sums 
          received by Borrower in anticipation of the sale and 
          delivery of Eligible U.S. Inventory, and (ii) all 
          Eligible U.S. Inventory on lease to others. The Lender 
          may determine on a daily basis whether any Inventory 
          constitutes and continues to constitute Eligible U.S.
          Inventory, and if any Eligible U.S. Inventory subse-
          quently becomes ineligible for any reason, its ineli-
          gibility shall become effective immediately.  In 
          making its determination of Eligible U.S. Inventory, 
          the Lender will consider whether Inventory satisfies 
          and continues to satisfy the following requirements:

               (a)  The Inventory is lawfully owned by Borrower, 
          is not subject to any lien, claim, consignment,

          security interests in such Inventory;

          Lien whatsoever, except for the Lender's security 
          interest and Permitted Liens, and a currently effec-
          tive UCC financing statement filed by the Lender 
          against the Borrower covering such Inventory is on 
          file in all appropriate filing locations;

               (c)  The Inventory arose or was acquired in the 
          ordinary course of Borrower's business and no sub-
          stantial portion thereof represents returned, rejected 
          or damaged goods; 

               (d)  No Account, account receivable or document 
          of title has been created or issued with respect to 
          such Inventory; 

               (e)  Each of the warranties and representations 
          set forth in Section 10.1 hereof has been affirmed 
          with respect thereto at the time the most recent 
          Schedule of Inventory was provided to Lender;

               (f)  The Inventory does not represent work in 
          process, spare parts, packaging and shipping materials, 
          supplies, or returned or defective Inventory; and

               (g) The Inventory is not otherwise regarded by 
          Lender as unsuitable collateral.

                    -----------------------
          anything to the contrary contained in this Agreement 
          or any of the other Loan Documents, the aggregate
          amount of the Loans and Banker's Acceptances shall

          Section 7.19, the Lender shall test the Borrower's 
          compliance on a quarterly basis using the consolidated

the Loan Documents are true and correct as of the date hereof, and no

reason of any matter, cause or thing from the beginning of the world 
through and including the date of this Amendment, arising directly or in-

particular section or sub-section of this Amendment unless otherwise 
specifically noted in this Amendment.  The headings of the sections and 
subsections of this Amendment are for convenience of reference only and 
shall not be considered a part hereof nor shall they be deemed to limit or 
otherwise affect any of the terms or provisions of this Amendment.  If any 
portion of this Amendment shall be unenforceable for any reason whatsoever,
the balance of this Amendment shall not in any way be affected thereby and 
shall be remain enforceable to the fullest extent allowed by law.

     12.  Entire Agreement.  This Amendment and certain other documents of 
          ----------------

cerning the modification of the Loan Documents, and all prior agreements 
relating to the modification of the Loan Documents are superseded in their 
entirety by the provisions thereof.  No promise, representation or warranty
not contained herein has been made by Lender to induce Borrower to execute 
this Amendment.

     13.  Binding Upon Successors and Assigns.  This Amendment shall inure 
          -----------------------------------

MENT FOR LENDER TO ENTER INTO THIS AMENDMENT.

     FOR VALUE RECEIVED, TECHDYNE, INC., a Florida corporation (the 
"Borrower" or the "undersigned") hereby promises to pay to the order of 
BARNETT BANK, N.A., a national banking association (together with its 
successors and assigns, "Lender") (Lender, together with any subsequent 
holder hereof, being sometimes referred to as the "Holder") at the office of
Lender, at 101 Hialeah Drive, Second Floor, Hialeah, Florida 33010, or at 
such other place as Holder may designate to Borrower in writing from time 
to time, the principal sum of ONE MILLION SIX HUNDRED THOUSAND AND NO/100 
DOLLARS ($1,600,000.00), or so much thereof as may be outstanding hereunder,
with interest on the principal balance of this Note outstanding from time to
time (which amount is hereinafter defined as the "Principal Sum") at the 
rate set forth below, together with all other fees and charges hereinafter 
provided for, in same day funds and lawful money of the United States of 
America that shall at the time of payment be legal tender for the payment 
of all debts and dues, public and private.  Said principal and interest 
shall be due and payable as provided below. 

     Section 1.  Certain Definitions.  In addition to the terms defined 
                 -------------------
elsewhere in this Note, as used herein, the following terms shall have the 
indicated definitions:

          Section 1.01  "Advance" shall mean any advance of principal made 
by Holder under this Note.

          Section 1.02  "Applicable Rate" shall mean an interest rate equal
to the Prime Rate, changing when and as the Prime Rate changes.

          Section 1.03  "Business Day" shall mean any day that is not a 
Saturday or Sunday or a day on which banks are required or permitted to be 
closed in the State of Florida.

          Section 1.04  "Lender" shall mean Barnett Bank, N.A., a national 
banking association, and its successors and assigns.

          Section 1.05  "Loans" shall mean all loans and advances made by 
the Lender to Borrower pursuant to the Loan Agreement.

          Section 1.06  "Loan Agreement" shall mean the Loan and Security 
Agreement dated February 8, 1996 by and between Borrower and Barnett Bank 
of South Florida, N.A., as amended by a First Amendment to Loan and 
Security Agreement, Loan Agreement and Security Agreement and Second Amend-
ment to Loan and Security Agreement of even date herewith, and all other 
amendments, modifications and supplements thereto.

<PAGE>

          Section 1.07  "Loan Documents" shall have the meaning therefor 
set forth in the Loan Agreement.     

          Section 1.08  "Maturity Date" shall mean the earlier to occur of 
(a) May 1, 2000, or (b) the date upon which the Principal Sum, all interest
accrued thereon, and all other sums payable under this Note shall become 
due and payable pursuant to Section 6 below.

          Section 1.09  "Note" shall mean this Revolving Promissory Note, 
which evidences the Loans, as it may be amended from time to time hereafter.

          Section 1.10  "Post-Default Rate" shall mean an annual rate of 
interest equal to five percent (5%) per annum above the Applicable Rate, 
changing when and as the Applicable Rate changes; provided, however, that 
in no event shall the Post-Default Rate exceed the highest rate per annum 
allowable by applicable law, rule, or regulation in effect from time to 
time.

          Section 1.11  "Prime Rate" shall mean the annual rate of interest
announced from time to time by Barnett Banks, Inc. or its successor as its 
prime rate.  The Prime Rate is a reference rate for the information and use 
of Lender in establishing the actual rates to be charged its borrowers.  
If Barnett Banks, Inc. or its successor shall cease to announce a prime 
rate, then the "Prime Rate" shall be such substitute prime rate as may be 
reasonably selected by Lender.

          Section 1.12  "Principal Sum" shall mean the entire outstanding 
principal balance of this Note as of the date upon which such calculation 
or determination shall be made.

     Section 2.  Payment of Principal and Interest, Revolving Loan.
                 -------------------------------------------------

          Section 2.01  This Note evidences all loans made by the Holder 
to Borrower pursuant to the terms of the Loan Agreement, and all such 
Loans shall be deemed Advances hereunder.  Subject to the terms and condi-
tions of the Loan Agreement, Borrower may borrow, repay and reborrow 
principal sums under this Note from time to time and this Note shall remain
in effect and evidence all such advances and re-advances hereunder; 
provided, however, that the aggregate principal amount outstanding here-
under at any one time shall not exceed $1,600,000.  Reference should be 
made to the Loan Agreement for the term, conditions and provisions appli-
cable the loans evidenced hereby and the making and repayment thereof.

          Section 2.02  This Note shall bear, and Borrower shall pay to 
Holder, interest on the Principal Sum at a rate per annum equal to the 
Applicable Rate; provided, however, that upon the occurrence any default 
under this Note or any of the other Loan Documents, the interest rate 
payable on the entire Principal Sum from the date of default (regardless 
of whether or not this Note is accelerated by the Holder) shall be the 
Post-Default Rate.  

          Section 2.03  Interest only on the Principal Sum shall be payable
on the fifteenth (15th) day of each month in arrears commencing on the 
fifteenth (15th) day of the first month subsequent to the initial Advance 
hereunder and continuing thereafter through and until the Maturity Date, 
at which time the Principal Sum, together with all accrued interest 
thereon, shall become immediately due and payable.

<PAGE>

     Section 3.  Payments and Computations.  All payments on account of 
                 -------------------------
the Loan shall be made not later than 1:00 p.m. (Miami time) on the day 
when due, in lawful money of the United States in same day funds and shall 
be first applied to fees and other charges when due and payable under the 
applicable provisions of this Note and the other Loan Documents, then to
interest on the unpaid Principal Sum and the remainder to the reduction of 
the Principal Sum.  All computations of interest under this Note shall be 
calculated on the basis of a 360-day year, but charged on the basis of the 
actual number of days elapsed in any calendar year or part thereof (i.e., 
the interest for each day on which any principal is outstanding shall be 
calculated at the annual interest rate divided by 360), provided, however, 
interest at the Post-Default Rate shall be calculated on the basis of a 
365 or 366 day year (whichever is applicable) for the actual number of 
days elapsed in the period for which such Post-Default Rate shall be appli-
cable.

     Section 4.  No Usury.  It is hereby expressly agreed that if under any
                 --------
circumstances whatsoever fulfillment of any provision of this Note, at the 
time performance of such provision shall be due, shall involve transcending
the limit validly prescribed by applicable usury statutes or any other laws
with regard to obligations of like character and amount, then ipso facto the
obligations to be fulfilled shall be reduced to the limit of such statutes 
or laws, so that in no event shall any exaction be possible under this Note
that is in excess of the limit, but such obligation shall be fulfilled to 
the maximum limit.  All agreements herein are expressly limited so that in 
no contingency or event whatsoever, whether by reason of advancement of 
the proceeds hereof, acceleration of maturity of the unpaid Principal Sum 
hereof, or otherwise shall the amount paid or agreed to be paid to Lender 
hereof for the use, forbearance or detention of the money to be advanced 
hereunder exceed the highest lawful rate.  In the event the maximum rate 
permitted to be paid on promissory notes and agreements of the type contem-
plated hereunder is ever increased, the maximum rate of interest hereunder 
shall be adjusted simultaneously with the effective date of such increase 
to coincide with the rate established by such law.  In the event such 
maximum rate is eliminated, the maximum rate of interest hereunder shall 
be adjusted simultaneously with the effective date of the amendment elim-
inating the maximum usury rate which, however, shall never exceed any 
criminal usury rate then in effect.  In the event the total liability for 
payments of interest and payments in the nature of interest including, 
without limitation, all charges, fees, exactions or other sums which may 
at any time be deemed to be interest shall, for any reason whatsoever, 
result in an effective rate of interest, which for any month or other 
interest payment period exceeds the limit imposed by any applicable usury 
laws, all sums in excess of those lawfully collectible as interest for 
the period in question shall, without further agreement or notice by, 
between or to any party hereto, be applied to reduce the accrued interest 
hereunder, if any, and then to a reduction of the Principal Sum immediately
upon receipt of such sums by the Holder hereof, or shall be refunded to 
Borrower, with the same force and effect as though the undersigned had 
specifically designated such excess sums to be so applied provided, 
however, that the Holder of this Note may, at any time and from time to 
time, elect, by notice in writing to the undersigned, to waive, reduce or 
limit the collection of any sums in excess of those lawfully collectible 
as interest rather than accept such sums and apply them as set forth above.
It is the intention of the parties that the Borrower does not intend or 
expect to pay nor does the Holder intend or expect to charge, accept or 
collect any interest under this Note, the Loan Agreement or any of the 
other Loan Documents greater than the highest rate of interest which may 
be charged under applicable law.

<PAGE>

     Section 5.  Prepayment.  The Principal Sum may be prepaid in whole or 
                 ----------
in part at any time without penalty in accordance with the terms of the 
Loan Agreement.

     Section 6.  Default.  Should any "Event of Default" as defined in the 
                 -------
Loan Agreement occur, or should any default occur in the payment or per-
formance of any of the covenants or conditions contained in this Note, in 
any Swap Agreement, or in any other Loan Document, then upon the occurrence
of any such event, the Principal Sum, all interest accrued thereon, all 
charges and fees which are part of the Loan, and any other sums payable 
under this Note, the Loan Agreement and the other Loan Documents shall, at 
the option of Holder, and without notice, demand or presentment for payment
to Borrower or any other person or entity, at once become due and payable 
and may be collected forthwith, regardless of the stipulated date of 
maturity, anything herein or in the other Loan Documents to the contrary 
notwithstanding, all without any relief whatever from any valuation or 
appraisement laws, and payment thereof may be enforced and recovered in 
whole or in part at any time by one or more of the remedies provided to 
Holder in this Note, in the Loan Agreement, or in any of the other Loan 
Documents or otherwise available at law or in equity.  Interest shall 
accrue on the Principal Sum from the date of any default under this Note, 
the Loan Agreement or any of the other Loan Documents, regardless of 
whether or not there shall have been an acceleration of the payment of 
principal as set forth herein, at the Post-Default Rate.

     Section 7.  Collateral Security.  The payment of this Note is secured
                 -------------------
by the Loan Agreement and the other Loan Documents.

     Section 8.  Late Charges.  In order to compensate Holder for the loss 
                 ------------
and expense occasioned by delinquencies in the payment provisions hereof, 
Borrower shall pay to Holder on demand, in addition to any interest or 
other charges under the Loan, a service charge for the collection of late 
payments equal to $.05 for each $1.00 or any part thereof of any delinquent
payment due under this Note, the Loan Agreement or any of the other Loan 
Documents more than ten (10) days past due.  Such late charge shall auto-
matically accrue and be due and payable on that date which is ten (10) days
after the due date of any payment.  Failure to pay such late charges within
ten (10) days after demand shall constitute a default under this Note.

     Section 9.  Time of Essence.  Time is of the essence hereof with 
                 ---------------
regard to the performance of all of the terms, provisions and conditions 
hereof on the part of Borrower.

     Section 10. Waivers and Miscellaneous.
                 -------------------------

          Section 10.01  The remedies of Holder, as provided herein and in 
the other Loan Documents, shall be cumulative and concurrent and may be 
pursued singly, successively or together, at the sole discretion of Holder,
and may be exercised as often as occasion therefor shall occur; and the 
failure to exercise any such right or remedy shall in no event be construed 
as a waiver or release thereof.

          Section 10.02  The undersigned and any endorsers, sureties, 
guarantors and all others who are or may become liable for the payment 
hereof (a) severally waive presentment for payment, demand, notice of 
demand, notice of nonpayment or dishonor, protest and notice of protest of 
this Note, and all other notices in connection with the delivery, accep-
tance,

<PAGE>

performance or enforcement of the payment of this Note, (b) expressly 
consent to all extensions of time, renewals, postponements of time of 
payment of this Note or other modifications hereof from time to time prior 
to or after its maturity date without notice, consent or consideration to
any of the foregoing, (c) expressly agree to any substitution, exchange, 
addition or release of any of the other Loan Documents, any addition or 
release of collateral for the payment hereof, or the addition or release 
of any party or person primarily or secondarily liable hereon, (d) expressly
agree that Holder shall not be required first to institute any suit or to 
exhaust its remedies against the undersigned or any other person or party 
liable hereunder or under the other Loan Documents or against any col-
lateral in order to enforce the payment of this Note, and (e) expressly 
agree that, notwithstanding the occurrence of any of the foregoing (except
the express written release by Holder of any such person, which release 
shall not release, limit or otherwise affect the liability of any person 
not specifically released), the undersigned and all endorsers, sureties,
guarantors and all others who are or may become liable for the payment 
hereof shall be and remain, jointly and severally, directly and primarily 
liable for all sums due under this Note and the other Loan Documents 
subject to the terms and conditions hereof.

          Section 10.03  Holder shall not be deemed, by any act or 
omission, to have waived any of its rights or remedies hereunder unless 
such waiver is in writing and signed by Holder and, then, only to the 
extent specifically set forth in the writing.  A waiver with reference
to one event shall not be construed as continuing or as a bar to, or 
waiver of, any right or remedy as to a subsequent event.

          Section 10.04  Neither this Note nor any provision hereof may 
be changed or terminated orally, but only by an instrument in writing 
signed by the party against whom enforcement of the change or termination 
is sought.

          Section 10.05  Failure to accelerate the Loan by reason of the 
default in any payment, or the acceptance of a past due payment, shall not 
be construed as a novation of the contract or a waiver of the right of 
Lender to thereafter insist upon strict compliance with the terms of this 
Note without previous notice of such intention being given to Borrower.

          Section 10.06  Borrower hereby waives and renounces all rights 
to the benefits of any appraisement, exemption and homestead now provided, 
or which may hereafter be provided, by the Constitution and laws of the 
United States of America and of any state thereof to and in all its 
property, real and personal, against the enforcement and collection of 
this obligation.

          Section 10.07  The section headings of this Note are for refer-
ence purposes only and are to be given no effect in the construction or 
interpretation of this Note.

          Section 10.08  The words "herein", "hereof", hereunder" and other
words of similar import refer to this Note as a whole and not to any par-
ticular section of this Note unless specifically stated otherwise in this 
Note.

          Section 10.09  All initially capitalized terms used herein,

                   UNCONDITIONAL AND CONTINUING GUARANTY
                       OF PAYMENT AND PERFORMANCE


     THIS GUARANTY ("Guaranty") is made as of the 29th day of December, 
1997, by MEDICORE, INC., a Florida corporation (the "Guarantor") in favor 
of BARNETT BANK, N.A., a national banking association ("Lender").

                           R E C I T A L S :

     A.   Lender has agreed to make a revolving credit loan facility avail-
able to Techdyne, Inc., a Florida corporation ("Borrower"), in the aggre-
gate principal amount at any one time outstanding of $1,600,000 (all loans 
now or hereafter made under such facility are collectively called the 
"Loans").

     B.   The Loans shall be evidenced by a Revolving Promissory Note of 
even date herewith executed by Borrower to the order of Lender (as same may 
be amended, modified, extended or renewed from time to time, without the 
necessity of notice to or the consent of the Guarantor, the "Note").

     C.   The Loans are to be made pursuant to, and are secured by, among 
other documents, a Loan and Security Agreement dated February 8, 1996 
between Borrower and Barnett Bank of South Florida, N.A., as amended by a 
First Amendment to Loan and Security Agreement, Loan Agreement, and 
Security Agreement dated July 31, 1997, and Second Amendment to Loan 
Agreement of even date herewith between Borrower and Lender (as so amended
and as the same may be amended, modified, extended or renewed from time to 
time, without the necessity of notice to or the consent of the Guarantor, 
the "Loan Agreement").

     D.   Lender may from time to time issue and renew banker's acceptances
at the request of the Borrower under or in connection with the Loan Agree-
ment (all such banker's acceptances, as the same may be amended, modified, 
extended or renewed from time to time, without the necessity of notice to 
or the consent of the Guarantor, are collectively called the "Banker's 
Acceptances").  All agreements and other documents from time to time 
executed in connection with the Banker's Acceptances or any of them, as 
such agreements and other documents may be amended, modified, extended or 
renewed from time to time, without the necessity of notice to or the 
consent of the Guarantor, are collectively called the "Acceptance Agree-
ments".

     E.   The Borrower is a subsidiary of Guarantor, and accordingly, the 
Guarantor will benefit from the Loans, the issuance of the Banker's Accep-
tances and all transactions relating thereto.

     F.   Lender would not make the Loans or issue any Banker's Acceptances
solely upon the covenants of the Borrower under the Note, Loan Agreement, 
Acceptance Agreements and other loan documents, but requires, as further 
security therefor, an unconditional and irrevocable guaranty of payment and
performance respecting the Loans and the Acceptance Agreements from 
Guarantor.

     NOW, THEREFORE, in consideration of the premises, and to induce Lender
to make the Loans and to issue the Banker's Acceptances, and in considera-
tion thereof, Guarantor guarantees and agrees as follows: 

<PAGE>

     1.   Recitations.  Each and all of the foregoing recitals are true 
          -----------
and correct and are incorporated herein by reference. 

     2.   Capitalized Terms.  All capitalized terms utilized in this 
          -----------------
Guaranty, unless specifically otherwise defined herein, shall have the 
meanings assigned to such terms in the Loan Agreement.

     3.   Guaranty.  Guarantor hereby absolutely, irrevocably and uncondi-
          --------
tionally guarantees (as primary obligor and not merely as sureties) to 
Lender and its successors and assigns the full and prompt payment (whether 
at stated maturity, by acceleration, or otherwise) and performance of the 
"Obligations" as hereinafter defined.  "Obligations" shall mean:

          (a)  All "Obligations" as such term is defined in the Loan 
     Agreement;

          (b)  All principal, interest, attorneys' fees, loan fees, liabil-
     ities for costs and expenses and all other indebtedness, obligations 
     and liabilities of Borrower to Lender at any time created or arising 
     under or in connection with the Loans, the Banker's Acceptances, the 
     Note, Loan Agreement, Acceptance Agreements, or any other document 
     now or hereafter executed in connection with the Loans or the Banker's
     Acceptances (or any of them) or as security for the Loans or any of 
     the Banker's Acceptances or any amendment, extension, renewal, or 
     modification thereto or substitution therefor (which may be made with
     out notice to or the consent of the Guarantor).  The Loan Agreement,
     Note, Acceptance Agreements and all other documents evidencing, 
     securing or otherwise relating to the Loans, the Banker's Acceptances
     or any of them, whether now or hereafter existing, as the same may be 
     amended, modified, extended or renewed from time to time, without the 
     necessity of notice to or the consent of the Guarantor, are sometimes 
     collectively called the "Loan Documents";

          (c)  All agreements, covenants, indemnities, terms, conditions, 
     and other obligations to be performed by, or on behalf of, Borrower 
     under the Loan Documents; and

          (d)  All costs, expenses and fees, including but not limited to 
     court costs and attorneys' fees, arising in connection with, or as a 
     consequence of the non-payment, non-performance or non-observance of 
     all amounts, indebtedness, obligations and liabilities of Borrower to 
     Lender described in items (a), (b) and (c) of this Section 3.

Upon payment and performance in full of the Obligations and the termination
of any further liability of Lender under the Loan Documents and the 
Banker's Acceptances, this Guaranty shall terminate, subject, however, to 
reinstatement pursuant to Section 10 below if any payment made with respect
to the Obligations is rescinded or must otherwise be restored or returned 
by Lender.

     4.   Guaranty of Payment.  This is an irrevocable, absolute, contin-
          -------------------
uing guaranty of payment (inter alia) and not a guaranty of collection and 
is in no way conditioned or contingent upon any attempt to collect from or 
enforce performance or compliance by the Borrower or upon any other event, 
contingency or circumstance whatsoever.  If for any reason the Borrower 
shall fail or be unable duly, punctually and fully to pay and perform the 
Obligations as and when the same shall become due, the Guarantor, without 
demand, presentment, protest or notice of any kind, will forthwith pay or 
perform the Obligations in accordance with the terms of such Loan Documents.
All such payments shall be made in lawful money of the United States and 
at the place specified in the Note, with interest thereon until paid at 
the rate set forth in the Loan

<PAGE>

Documents.  The Guarantor, promptly after demand, will pay to the Lender 
the reasonable costs and expenses of collecting such amounts or otherwise 
enforcing this Guaranty, including, without limitation, the reasonable 
fees and expenses of counsel (before trial, at trial, at all appellate 
levels, in bankruptcy, and otherwise).  Guarantor waives any right to 
require that any action be brought against Borrower or any other person 
or to require that resort be made to any security and Lender may, at its 
option, proceed against the Guarantor in the first instance to collect any
monies the payment of which is guaranteed hereby, without first proceeding
against Borrower or any other person and without first resorting to any 
security held by it as collateral or to any other remedies.  The liability 
of the Guarantor hereunder shall be in no way affected or impaired by an 
acceptance by Lender of any security for, or other guarantors upon, any 
indebtedness, liability or obligation of Borrower to the Lender, or by 
any failure, delay, neglect or omission by Lender to realize upon or 
protect any such indebtedness, liability or obligation or any notes or 
other instruments evidencing same or any collateral or security therefor.

     5.   Obligations of Guarantor Unconditional.  The obligations of the 
          --------------------------------------
Guarantor under this Guaranty shall be primary, absolute and unconditional 
obligations of the Guarantor, shall not be subject to any counterclaim, 
set-off, deduction, diminution, abatement, recoupment, suspension, defer-
ment, reduction or defense based upon any claim the Guarantor or any other
person may have against the Borrower, the Lender or any other person, and 
shall remain in full force and effect without regard to, and shall not be 
released, discharged or in any way affected by, any circumstance, contin-
gency or condition whatsoever (whether or not the Guarantor, the Borrower 
or the Lender shall have any knowledge or notice thereof and whether 
occurring prior to or after the date of this Guaranty), including, without 
limitation:

          (a)  Any termination (other than by payment in full, subject to 
     the provisions of Section 10 below), amendment or modification of or 
     deletion from or addition or supplement to or other change, modifica-
     tion, extension, substitution or renewal of any of the Loan Documents 
     or any other instrument or agreement applicable to any of the parties 
     to any of the Loan Documents;

          (b)  Any furnishing or acceptance of any security, or any release
     of any security, for the Obligations, or the failure of any security 
     or the failure of any person to perfect any interest in any collateral;

          (c)  Any failure, omission or delay on the part of the Borrower 
     to conform or comply with any term of any of the Loan Documents or any
     other instrument or agreement referred to in subsection (a) above, 
     including, without limitation, failure to give notice to the Guarantor
     of the occurrence of a default under any Loan Document;

          (d)  Any waiver of the payment, performance or observance of any 
     of the obligations, conditions, covenants or agreements contained in 
     any Loan Document or any other waiver, consent, extension, indulgence, 
     compromise, settlement, release or other action or inaction under or 
     in respect of any of the Loan Documents or any other instrument or 
     agreement referred to in subsection (a) above, or any obligation or 
     liability of the Borrower, or any exercise or non-exercise of any 
     right, remedy, power or privilege under or in respect of any such 
     instrument or agreement or any such obligation or liability;

          (e)  Any failure, omission or delay on the part of the Lender to 
     enforce, assert or exercise any right, power or remedy conferred on 
     it in this Guaranty, or any such 

<PAGE>

     failure, omission or delay on the part of the Lender in connection 
     with any Loan Document or any other action or inaction on the part of 
     the Lender;

          (f)  Any voluntary or involuntary bankruptcy, insolvency, reor-
     ganization, arrangement, readjustment, assignment for the benefit of 
     creditors, composition, receivership, conservatorship, custodianship, 
     liquidation, marshalling of assets and liabilities or similar pro-
     ceedings with respect to the Borrower, the Guarantor or any other 
     person or any of their respective properties or creditors, or any 
     action taken by any trustee or receiver or by any court in any such 
     proceeding;

          (g)  Any limitation on the liability or obligations of the 
     Borrower or any other person under any of the Loan Documents or any 
     discharge, termination or cancellation (other than by payment in 
     full), frustration, irregularity, invalidity or unenforceability, in 
     whole or in part, of any of the Loan Documents or any other agreement 
     or instrument referred to in subsection (a) above or any term hereof;

          (h)  Any merger or consolidation of the Borrower or the Guarantor
     into or with any other corporation, or any sale, lease or transfer or 
     any of the assets of the Borrower or the Guarantor to any other person;

          (i)  Any change in the relationship between the Borrower and the 
     Guarantor or any termination of such relationship;

          (j)  Any law, regulation, or decree now or hereafter in effect in 
     any jurisdiction which might in any manner affect any of the Obliga
     tions or the rights of Lender with respect thereto;

          (k)  Any release or discharge, by operation of law, of the 
     Guarantor from the performance or observance of any particular obli-
     gation, covenant or agreement contained in this Guaranty; 

          (l)  Any counterclaim, defense, reduction or set-off the Borrower
     may have with respect to any of the Obligations; or

          (m)  Any other occurrence, circumstance, happening or event what-
     soever, whether similar or dissimilar to the foregoing, whether 
     foreseen  or unforeseen, and any other circumstance which might other-
     wise constitute a legal or equitable defense or discharge of the 
     liabilities of a guarantor or surety or which might otherwise limit 
     recourse against the Guarantor.

     6.   Full Recourse Obligations.  The obligations and liabilities of 
          -------------------------
the Guarantor set forth herein constitute the full recourse obligations of 
the Guarantor enforceable against the Guarantor to the full extent of all 
its assets and properties.

     7.   Waiver.  The Guarantor unconditionally waives, to the fullest 
          ------
extent permitted by applicable law:

          (a)  Notice of acceptance of this Guaranty by Lender, or of the 
     creation, renewal or accrual of any liability of Borrower, present or 
     future, or of the reliance of Lender upon this Guaranty (it being 
     understood that every indebtedness, liability and obligation

<PAGE>     

     of Borrower to Lender shall conclusively be presumed to have been 
     created, contracted or incurred in reliance upon this Guaranty);
 
          (b)  Notice of any of the matters referred to in Section 5;

          (c)  Notice to the Guarantor of the incurrence of any of the 
     Obligations, notice to the Guarantor or the Borrower of any breach or 
     default by the Borrower with respect to any of the Obligations, notice
     of acceleration or intent to accelerate, or any other notice that may 
     be required, by statute, rule of law or otherwise, to preserve any 
     rights of the Lender against the Borrower or the Guarantor;

          (d)  Presentment to or demand of payment from the Borrower, the 
     Guarantor or any other person with respect to the Note or protest for 
     nonpayment or dishonor;

          (e)  Any right to require Lender to enforce, assert or exercise 
     any right, power, privilege or remedy conferred in  any Loan Document 
     or otherwise and notice of Lender's exercise of any such right, 
     privilege or remedy;

          (f)  Any requirement of diligence on the part of the Lender;

          (g)  Any requirement to exhaust any remedies or to mitigate the 
     damages resulting from any default under any Loan Document;

          (h)  Defense of the statute of limitations in any action here-
     under or for the collection of any indebtedness or the performance of 
     any Obligations hereby guaranteed; and any defense arising by virtue 
     of (i) the lack of authority of the Borrower or any other person, or 
     (ii) the failure of Lender to file or enforce a claim of any kind;

          (i)  Any notice of sale, transfer or other disposition of any 
     right, title to or interest in the Loan Documents by the Lender;

          (j)  Any duty on the part of Lender to disclose to Guarantor any 
     facts which Lender may now or hereafter know about Borrower, regard-
     less of whether Lender has reason to believe that any such facts 
     materially increase the risk beyond that which the Guarantor intends 
     to assume, has reason to believe that such facts are unknown to 
     Guarantor or has a reasonable opportunity to communicate such facts 
     to Guarantor, it being understood and agreed the Guarantor is fully 
     responsible for being and keeping informed of the financial condition 
     of Borrower and of all circumstances bearing on the risk of non-payment
     of all Obligations hereby guaranteed; and

          (k)  Any other circumstance whatsoever which might otherwise 
     constitute a legal or equitable discharge, release or defense of a 
     guarantor or surety or which might otherwise limit recourse against 
     the Guarantor.

     8.   Waiver of Subrogation.  The Guarantor hereby irrevocably and 
          ---------------------
forever waives any claim, remedy or right which the Guarantor may now have 
or hereafter acquire against the Borrower that arises hereunder and/or as a
result of the payment or performance by the Guarantor under this Guaranty, 
including, without limitation, any claim, remedy or right of subrogation, 
reimbursement, exoneration, indemnification, or participation in any claim, 
remedy or right of Lender against the Borrower or any security which Lender 
now has or hereafter acquires, whether 

<PAGE>

or not such claim, remedy or right arises in equity, under contract, by 
statute, under common law or otherwise.

     9.   Consent to Extensions, Renewals and Releases.  Guarantor hereby 
          --------------------------------------------
agrees that Lender may, from time to time, before or after any default by 
Borrower, with or without further notice to or assent from the Guarantor, 
without in any manner affecting the liability of Guarantor, and upon such 
terms and conditions as it may deem advisable:  (a) extend in whole or in 
part (by renewal or otherwise), modify, accelerate, change or release any 
indebtedness, liability or obligation of Borrower or of any other person 
liable for any indebtedness, liability or obligation of Borrower, or waive 
any default with respect thereto; (b) sell, release, surrender, modify, 
impair, exchange, substitute or (if a chose or choses in action) extend 
the duration or the time for performance or payment of any and all 
property, of any nature and from whomsoever received, held by Lender as 
security for the payment or performance of any indebtedness, liability or 
obligation of Borrower to Lender; and (c) settle, adjust or compromise any 
claim of Lender against Borrower or any other person liable for any 
indebtedness, liability or obligation of Borrower.  Guarantor hereby rati-
fies and confirms any such extension, renewal, change, release, waiver, 
surrender, exchange, modification, impairment, substitution, settlement, 
adjustment or compromise and agree that the same shall be binding upon 
Guarantor, and Guarantor hereby expressly waives any and all defenses, 
counterclaims or offsets which Guarantor might or could have by reason 
thereof, it being understood that Guarantor shall at all times be bound 
by this Guaranty and remain fully liable to Lender hereunder.

     10.  Effect of Bankruptcy Proceedings, etc.  This Guaranty shall 
          -------------------------------------
continue to be effective or be automatically reinstated, as the case may 
be, if at any time payment, in whole or in part, of any of the sums due to 
the Lender pursuant to the terms of any Loan Document is rescinded or must 
otherwise be restored or returned by the Lender upon the insolvency, bank-
ruptcy, dissolution, liquidation or reorganization of the Borrower or any 
other person, or upon or as a result of the appointment of a custodian, 
receiver, trustee or other officer with similar powers with respect to the 
Borrower or other person or any substantial part of its property, or other-
wise, all as though such payment had not been made.  If an event permitting
the acceleration of the maturity of the principal amount of the Note or 
any of the obligations of Borrower under the Acceptance Agreements shall 
at any time have occurred and be continuing, and such acceleration shall 
at such time be prevented by reason of the pendency against the Borrower 
or any other person of a case or proceeding under a bankruptcy or insol-
vency law, the Guarantor agrees that, for purposes of this Guaranty and 
its obligations hereunder, the maturity of the principal amount of the 
Note or such other obligations shall be deemed to have been accelerated 
with the same effect as if the Lender had accelerated the same in ac-
cordance with the terms of the Loan Documents and the Guarantor shall 
forthwith pay such principal amount, any interest thereon and any other 
amounts guaranteed hereunder, without further notice or demand.

     11.  Remedies.  In the event that Guarantor shall fail to perform 
          --------
promptly as herein provided, Lender shall have the right (from time to 
time, without first requiring performance on the part of the Borrower) to 
require payment and performance by the Guarantor of any Obligations, by 
action at law or in equity or both, and further to collect in any such 
action reasonable compensation for all loss, costs, damage, injury and 
expense sustained or incurred by Lender as a consequence of such breach.

     12.  Interest and Expenses of Enforcement.  Any sum required to be 
          ------------------------------------
paid by Guarantor to Lender pursuant to the terms hereof shall bear 
interest at the non-default rate set forth in the Loan Documents from the 
due date thereof until 10 days after demand from Lender

<PAGE>

and thereafter all such sums shall bear interest at the Post-Default Rate 
(as such term is defined in the Note) until paid.   Guarantor agrees to 
pay any and all costs and expenses incurred by Lender in enforcing any 
rights or remedies under this Guaranty, including, without limitation, all 
reasonable fees and expenses of the Lender's attorneys, including fees and 
expenses of any appeals, regardless of whether any specific legal pro-
ceedings should be commenced or initiated.

     13.  Consideration.  Guarantor acknowledges that its undertakings 
          -------------
hereunder are given in consideration of the Lender making the Loans to 
Borrower and issuing the Banker's Acceptances at the Borrower's request 
and that Lender would not make the Loans to Borrower or issue any Banker's 
Acceptance were it not for the execution and delivery of this Guaranty.

     14.  No Waiver.  No failure on the part of Lender to pursue any remedy
          ---------
hereunder or under the Loan Documents shall constitute a waiver on its part
of the right to pursue said remedy on the basis of the same or a subsequent
breach.  No extension, substitution, modification, amendment or renewal of 
the Loan Documents shall serve to waive the provisions hereof or discharge 
Guarantor from any obligation or liability herein contained in whole or in 
part, except to the extent expressly provided by Lender in writing.

     15.  Guaranty Independent.  Guarantor agrees that all of the obliga-
          --------------------
tions, agreements and liabilities hereunder are joint and several and are 
independent of and in addition to the undertakings of the Borrower pursuant
to the Loan Documents and any other obligations of Guarantor to Lender.  A 
separate action may be brought to enforce the provisions hereof whether or 
not Borrower is a party in any such action.  Borrower and Guarantor may be 
sued together, or any of them may be sued separately without first or 
contemporaneously suing the other.

     16.  Representations and Warranties.  The Guarantor hereby represents 
          ------------------------------
and warrants the following:

          notes thereto with respect to Guarantor furnished to Lender

          gent, as of their respective dates.

               (iii) There has been no adverse change in the financial con-
          dition or operations of Guarantor since the date of the most 
          recent financial statement given to Lender with respect to Guar-
          antor other than changes in the ordinary course of business, 
          none of which changes have been materially adverse individually 
          or in the aggregate.

          (b)  Other Arrangements.  Guarantor is not in default in the

tor, would individually or collectively have a material adverse effect on 
the Guarantor.

          (e)  Taxes.  Guarantor has filed all federal, state, provincial, 
               -----

     THIS AGREEMENT is dated as of the 29th day of December, 1997, among 
BARNETT BANK, N.A., a national banking association (hereinafter called the

                          W I T N E S S E T H

     WHEREAS, the Borrower has requested the Lender to make a $1,600,000 
revolving credit facility available to Borrower in accordance with the 
terms of a Loan and Security Agreement dated February 8, 1996 between 
Borrower and Barnett Bank of South Florida, N.A., as amended by a First 
Amendment to Loan and Security Agreement, Loan Agreement and Security 
Agreement dated July 31, 997 between Borrower and Lender and a Second 
Amendent to Loan and Security Agreement of even date hereiwth (as so 
amended and as it may be modified, amended, renewed or extended from time 
to time without the necessity of notice to or the consent of the Sub-
ordinating Creditor, the "Loan Agreement");

     WHEREAS, pursuant to the Loan Agreement, the Lender shall made loans 
(collectively, the "Loans") to Borrower and may issue banker's acceptances 
(collectively, the "Banker's Acceptances") at the request of Borrower;

     WHEREAS, the Loans are to be evidenced by a Revolving Promissory Note 
in the principal amount of $1,600,000.00 of even date herewith executed by 
Borrower in favor of Lender (as it may be modified, amended, renewed or 
extended from time to time without the necessity of notice to or the 
consent of the Subordinating Creditor, the "Note");

     WHEREAS, the Subordinating Creditor directly owns an interest in the 
Borrower and as such will enjoy substantial benefits from the availability 
to Borrower of the Loans and Banker's Acceptances.

     NOW, THEREFORE, in consideration of the Lender's execution of the Loan 
Agreement and making Loans and issuing Banker's Acceptances and in consider-
ation of the benefits accruing to the Subordinating Creditor by reason of 
said Loans and Banker's Acceptances, and as an inducement to the Lender to 
make said Loans and issue the Banker's Acceptances, the parties hereto 
agree as follows:

     1.   All capitalized terms used in this Agreement, unless otherwise 
defined herein, shall have the meanings set forth in the Loan Agreement.

     2.   The Subordinating Creditor hereby subordinates to the "Obliga
tions", as such term is defined in the Loan Agreement, whether now 
existing or hereafter arising, including without limitation, interest 
after the commencement of any bankruptcy proceeding affecting the Borrower,

     ments, substitutions, and modifications thereof; 

          (b)  All interest, fees, costs and other liabilities which may 
     now or hereafter be due in connection with the indebtedness identified
     in subsection (a) above, both prior to and subsequent to any bank-
     ruptcy of the Borrower; and 

          (c)  Any debts, claims, redemption rights, loan obligations or 
     any other obligations of any type whatever of the Borrower now or 
     hereafter held by the Subordinating Creditor as a result of or in 
     connection with the Subordinated Debt.

The indebtedness, interest, fees, costs, obligations and other liabilities 
identified in subsections (a), (b), and (c) above are collectively called 
the "Subordinated Debt".

     3.   Notwithstanding anything to the contrary provided in this Agree-
ment, the Borrower may make, and the Subordinating Creditor may receive, 
payments on the Subordinated Debt on a dollar for dollar basis from addi-
tional equity that is injected into Borrower or from the use, on a quarterly
basis, of retained earnings arising subsequent to March 31, 1995, so long 
as at the time of any payment of the Subordinated Debt:  (a) the Borrower

Loan Agreement as of the end of the most recent quarter, (b) both before 
and immediately after the contemplated payment, no Event of Default shall

notice and/or lapse of time, could constitute an Event of Default under 
the Loan Agreement.  The payments on the Subordinated Debt that are ex-
pressly permitted under this Section 3 are hereinafter called the 
"Permitted Reductions".

     4.   Except for the Permitted Reductions, no direct or indirect 
payment shall be made on or in connection with, or with respect to, the 
Subordinated Debt.  Except for the Permitted Reductions, the Senior Debt 
must be paid in full prior to any payment of any kind or nature on the 
Subordinated Debt and all claims of the Subordinating Creditor against the 
Borrower under or in connection with the Subordinated Debt are hereby 
assigned to Lender as security for all Senior Debt.  Subordinating Creditor
will, from time to time upon Lender's request, execute and file such 
documents (including, without limitation, financing statements) as the 
Lender deems necessary or appropriate to perfect, preserve or enforce its 
rights hereunder.  In the event that there is any promissory note or other 
evidence of indebtedness (whether now or hereafter existing) relating to 
the Subordinated Debt, then the Borrower and the Subordinating Creditor 
shall endorse the same with a legend stating that it is subject to this 
Agreement and, if so requested, will deliver the same to the Lender.  

     5.   The Borrower hereby agrees that while the Obligations or any part
thereof remain outstanding, it will not satisfy nor make any principal, 
interest or other payments of any nature whatsoever upon the Subordinated 
Debt (including debts, claims, redemption rights, loan obligations or any 
other obligations of any type whatever to the Subordinating Creditor) 
except as expressly permitted under Section 3 above.  The Borrower agrees 
that should it make any payment in

<PAGE>

contravention of this Agreement while any part of the Obligations remain 
outstanding, the same shall constitute an Event of Default under the Loan 
Agreement, entitling the Lender to exercise any and all remedies for 
default thereunder unless said payment is in the form of trade payables 
arising in the ordinary course of business between Borrower and Subor-
dinating Creditor.

     6.   The Subordinating Creditor hereby agrees as follows:

          (a)  The Subordinating Creditor will not accept or receive (di-
     rectly or indirectly) from the Borrower any payment in contravention 
     of this Agreement, nor will any Subordinating Creditor make any trans-
     fer to third parties not a party to this Agreement or take any other 
     action designed to secure indirectly from the Borrower the payment of 
     any sums in contravention of this Agreement.

          (b)  The Subordinating Creditor shall be liable to Lender for 
     any sums it accepts or receives from the Borrower in contravention of 
     this Agreement, and such sums, when remitted to Lender, shall be 
     applied to the Obligations in such order as Lender may elect in its 
     sole discretion.  All sums received by the Subordinating Creditor in 
     contravention of this Agreement shall be deemed to be trust funds 
     held for the benefit of Lender.

          (c)  In the event of the liquidation of the Borrower or distribu-
     tion of its assets, any obligation of the Borrower to the Lender 
     (including interest after the commencement of any proceeding under 
     Chapter 11 of the United States Code at the rate specified in the Loan
     Documents, whether or not such interest is an allowable claim in any 
     such proceeding) shall be satisfied and discharged before the Subor-
     dinating Creditor receives any distributive share or payment on 
     account of the obligations of the Borrower to Subordinating Creditor.

          (d)  The Subordinating Creditor agrees that it will not hereafter
     assign, transfer or convey all or any portion of the Subordinated Debt
     or any interest therein.

          (e)  The Subordinating Creditor will mark its books and records 
     and all documents evidencing the Subordinated Debt to reflect that 
     such debt is subordinated pursuant to the terms and conditions of 
     this Agreement.

     7.   All of the Obligations, whether now existing or hereafter arising 
(including, without limitation, interest after the commencement of any 
bankruptcy proceeding affecting the Borrower, whether under Title 11 of 
the United States Code or otherwise, at the rate specified in the Loan 
Documents, whether or not such interest is an allowable claim in any such 
proceeding) and any and all renewals, extensions, enlargements and modifi-
cations thereof, shall be entitled to the benefit of this Agreement and 
shall constitute Senior Debt.

     8.   Payments in contravention of this Agreement may be made by the 
Borrower only with express written approval of the Lender, which may be 
granted or denied in Lender's sole discretion.

<PAGE>

     9.   The Subordinating Creditor hereby represents and warrants to 
Lender that the Subordinated Debt constitutes the only liabilities of 
Borrower to the Subordinating Creditor, except for trade payables in the 
ordinary course of business.

     10.  This Agreement shall be binding upon, and inure to the benefit 
of, the parties hereto and their respective successors and assigns, 
including without limitation all successor owners of the Senior Debt or 
any portion thereof.

     11.  LENDER, BORROWER AND SUBORDINATING CREDITOR HEREBY KNOWINGLY, 
VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT TO A TRIAL BY JURY IN 
RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER OR IN 
CONNECTION WITH THIS AGREEMENT, THE SUBORDINATED DEBT, THE LOAN DOCUMENTS,

WRITTEN) OR ACTIONS OF ANY PERSON IN CONNECTION WITH THE OBLIGATIONS (AS 
DEFINED IN THE LOAN AGREEMENT), THE LOAN AGREEMENT, THE SUBORDINATED DEBT, 
THE SENIOR DEBT OR ANY DOCUMENTS RELATING TO THE FOREGOING.  THIS WAIVER

<PAGE>

obligations under the Loan Documents.  To the best of the Borrower's

default under any applicable statute, rule, order, decree, writ, injunction
or regulation of any governmental body (including any court).

all taxes and all other assessments or fees levied upon the Borrower, the
Guarantor or upon their respective properties to the extent that such taxes,
assessments or fees have become due.  No controversy in respect of income 
taxes is pending or, to the knowledge of the Borrower, threatened.

     4.4  Enforceability of Loan Documents: Compliance With Other Instru-
          ---------------------------------------------------------------
ments.  The Loan Documents are the legal, valid and binding obligations of

the Borrower and the Guarantor, enforceable against the Borrower and the 
Guarantor in accordance with their respective terms, subject to applicable 
bankruptcy, reorganization, arrangement, insolvency, moratorium, fraudulent
transfer, or other similar laws of general application relating to or 
affecting the rights or remedies of creditors, and general principles of

the Guarantor is in default with respect to any indenture, loan agreement, 
mortgage, lease, deed or similar agreement related to the borrowing of 
monies to which the Borrower or the Guarantor is a party or by which either
the Borrower or the Guarantor is bound.  Neither the execution, delivery or
performance of the Loan Documents, nor compliance therewith:  (a) conflicts
or will conflict with or results or will result in any breach of, or 
constitutes or will constitute with the passage of time or the giving of 
notice or both, a default under, (i) the Articles of Incorporation or 
Bylaws of the Borrower or the Guarantor, (ii) any law, order, writ, injunc-
tion or decree of anycourt or governmental authority, or (iii) any agree-

permits, certificates, inspections, consent and franchises necessary to 
continue to conduct their respective businesses as heretofore and presently
conducted and proposed to be conducted and to own or lease and operate 
their respective properties as now owned or leased by it.  None of such 
approvals, permits, certificates, consents, or franchises contains any 
term, provision, condition or limitations which is more burdensome than 
such as are generally applicable to Persons engaged in the same or similar 
business as the Borrower and Guarantor.

<PAGE>

     4.6  Event of Default.  No event has occurred and is continuing which
          ----------------

Default after notice or lapse of time or both.

     4.7  Margin Securities.  None of the transactions contemplated by 
          -----------------
this Agreement (including, without limitation thereof, the use of the pro-
ceeds of the Loan) will violate or result in a violation of the Securities 
Exchange Act of 1934, as amended, or any regulations issued pursuant there-
to.  The Borrower does not own or intend to carry or purchase directly or
indirectly any "margin securities" as that term is defined in Regulations 
G and U of the Board of Governors of the Federal Reserve System (the 
"Federal Reserve Board"), and the proceeds of the Loan will be used only 
for the purposes contemplated hereunder.  None of the proceeds of the Loan 
will be used, directly or indirectly, for the purpose of purchasing or 
carrying any margin security, for the purpose of reducing or retiring any

security or for any other purpose which might cause the Loan to be con-
sidered a "purpose credit" within the meaning of Regulations G, T, U or X
of the Federal Reserve Board.  The Borrower will neither take nor permit 
any agent acting on its behalf to take any action which might cause this 
Agreement or any document or instrument delivered pursuant hereto to 
violate any regulation of the Federal Reserve Board.

     4.8  Full Disclosure.  None of the Loan Documents, nor any statements 
          ---------------
furnished by or on behalf of the Borrower or the Guarantor to the Lender 
in connection with the Loan Documents, contains any untrue statement of a 
material fact or omits a material fact necessary to make the statements 
contained therein or herein not misleading.  To the Borrower's knowledge,
there is no fact which the Borrower has not disclosed to Lender in writing 
which materially and adversely affects or, to the Borrower's knowledge, 
will materially and adversely affect the Borrower, the Guarantor, Col-
lateral, the Lender's Liens in the Collateral or the priority thereof, 
the other assets, business, profits or conditions (financial or otherwise) 
of the Borrower, or the ability of the Borrower to perform the Obligations.

          ----------
pared in accordance with GAAP, contain no material misstatement or 
omission, and fairly present the financial position, assets and liabilities
of the Borrower as of the respective dates thereof and the results of 
operations and cash flows of the Borrower for the respective periods then 
ended.  Except for the transactions contemplated by this Agreement and 
except as may have otherwise been disclosed in the annual, quarterly and 
current reports (Forms 10-K, 10-Q, and 8-K, respectively) as filed with 
the SEC and delivered to Lender, since December 31, 1996, there has been no
material adverse change in the assets, liabilities or cash flows of the 
Borrower or in the results of the Borrower's operations or cash flows, and 
the Borrower has not incurred any obligation or liability which would 
materially and adversely affect its financial condition, business opera-
tions, cash flows or the Collateral.

applicable to the Borrower, the Collateral or the conduct of the Borrower's
or the Guarantor's business, including, without limitation, all Environ-
mental Laws, and there have been no citations, notices or orders of

which has resulted in a strike or other work action materially affecting
the Borrower;

shall maintain and preserve its corporate existence and all rights, privi-
leges and franchises now enjoyed; and the Borrower shall conduct its

repairs to, renewals of or replacements of its properties (except to the 
extent that any of such properties is obsolete or is being replaced) so 
that the efficiency of such property shall be fully maintained and 
preserved.  The Borrower shall file or cause to be filed in a timely 
manner all reports, applications, estimates and licenses which shall be 
required by any governmental authority and which, if not timely filed, 
would have a material adverse effect on the Borrower, the Collateral, the 
Lender's Liens in the Collateral or the priority of such Liens.

     5.6  Payment of Indebtedness: Performance of Other Obligations.  The
          ---------------------------------------------------------
Borrower shall pay all Indebtedness for borrowed money at maturity, all

assessed upon the Borrower when due and all other obligations in accordance
with customary trade practices, and comply with all acts, rules, regula-
tions and orders of any legislative, administrative or judicial body or 
official applicable to the operation of the Borrower's business; provided, 
however, that the Borrower may in good faith by appropriate proceedings 
and with due diligence contest any such taxes, assessments, governmental 
charges, acts, rules, regulations, orders and directions.  The Borrower 
shall also observe and remain in compliance with all laws, ordinances, 
governmental rules and regulations to which it is subject and obtain all 
licenses, permits, franchises or other governmental authorizations 
necessary to the ownership of its properties or the conduct of its 
business, and all covenants and conditions of all agreements and instru-
ments to which the Borrower is a party, which failure to comply or failure 
to obtain would materially and adversely affect the business, prospects, 
profits, properties or condition (financial or otherwise) of the Borrower.

in which the Borrower is engaged or which the Lender may otherwise require,
and all of such insurance shall be in such amount, for such periods, with 
such companies and in such form as shall be satisfactory to the Lender.  
Borrower shall deliver to the Lender certificates of insurance with respect
to the insurance required to be maintained by Borrower and Guarantor with 
satisfactory endorsements naming the Lender as additional insured there-
under.  Each policy of insurance shall contain a clause requiring the 
insurer to give not less than thirty (30) days prior written notice to 
the Lender before any cancellation of the policies for any reason whatso-
ever and a clause that the interest of the Lender shall not be impaired or
invalidated by any act or neglect of the Borrower, the Guarantor, or the 
owner of the property nor by the occupation of the premises wherein such 
property is located for purposes more 

<PAGE>

hazardous than are permitted by said policy.  The Borrower hereby directs 
all insurers under such policies of insurance on the Collateral to pay all 
proceeds payable thereunder directly to the Lender.  The Borrower hereby 
irrevocably makes, constitutes and appoints the Lender (and all officers, 
employees or agents designated by the Lender) as the Borrower's true and 
lawful attorney (and agent-in-fact) for the purpose of making, settling 
and adjusting claims under such policies of insurance, endorsing the name 
of the Borrower on any check, draft, instrument or other item or payment 
for the proceeds of such policies of insurance and for making all deter-
minations and decisions with respect to such policies of insurance so long
as any of the Obligations are outstanding; provided, however, that prior 
to the occurrence of an Event of Default hereunder, the Lender shall not 
settle or adjust any insurance claims without the prior written approval 
of Borrower.  If the Borrower or the Guarantor fails to obtain and maintain
any of the policies of insurance or to pay any premium in whole or in part,
then the Lender may, at the Borrower's expense, without waiving or 
releasing any obligation or default by the Borrower hereunder, procure the 
same, but shall not be required to do so.  All sums so disbursed by the 
Lender, including attorneys' fees, court costs, expenses and other charges
related thereto, shall be payable on demand by the Borrower to the Lender 
and shall be additional Obligations hereunder secured by the Collateral.  
The Borrower shall deliver to the Lender, promptly as rendered, true copies
of all reports made in any reporting forms to insurance companies.  Not 
less than thirty (30) days prior to the expiration date of the insurance
policies required to be maintained by the Borrower or Guarantor, the 
Borrower shall deliver to the Lender one or more certificates of insurance
evidencing renewal of the insurance coverage required hereunder plus such 
other evidence of payment of premiums therefor as the Lender may request.

          --------------------------------------------
maintain adequate books, accounts and records, and prepare all financial 
statements required under this Agreement in accordance with GAAP and in 
compliance with the regulations of any governmental regulatory body having 
jurisdiction over it; and permit employees or agents of the Lender at any
reasonable time to inspect the Borrower's properties, and to examine or 
audit the Borrower's books, accounts and records and make copies and 
memoranda of them.  The Borrower shall permit any representative of the 
Lender to visit and inspect any property of the Borrower, to examine all 
books of accounts, records, reports and other papers, to make copies and 
extracts therefrom, and to discuss the affairs, finances and accounts of 
the Borrower withits officers, employees and independent public accountants
(and by this provision the Borrower authorizes said accountants to discuss 
the finances and affairs of the Borrower), all at such reasonable times 
during normal business hours and as often as may be reasonably requested. 
Without limiting the generality of the foregoing, the Borrower shall permit
representatives of the Lender to conduct quarterly field examinations of 
the Borrower's premises and books and records (wherever located) during 
the Term; provided, however, that the Lender reserves the right at any 
time to increase the frequency of such examinations in its sole discretion.
The Lender shall not unreasonably interfere with the business of the 
Borrower in exercising any of the examination and audit rights granted to 
Lender under this Agreement, and Lender shall maintain the confidentiality 
of the information obtained from such examinations and audits in accordance
with applicable law.

     5.9  Compliance with ERISA.  The Borrower shall at all times make 
          ---------------------
prompt payment of contributions required to meet the minimum funding stand-
ards set forth in ERISA with respect

the Lender copies of any annual report required to be filed under ERISA in 
connection with each employee benefit plan; not withdraw from participation
in, permit the termination or partial termination of, or permit the occur-
rence of any other event with respect to any employee benefit plan that 
could result in liability to the Pension Benefit Guaranty Corporation; 
notify the Lender as soon as practicable of any Reportable Event and of 
any additional act or condition arising in connection with any employee 
benefit plan which the Borrower believes might constitute grounds for the 
termination thereof by the Pension Benefit Guaranty Corporation or for the 
appointment by the appropriate United States district court of a trustee to
administer such plan; and furnish to the Lender upon the Lender's request, 
such additional information about any employee benefit plan as may be 
reasonably requested.

     5.10 Compliance with Environmental Laws.  The Borrower shall comply, 
          ----------------------------------
and shall use its best efforts to cause the Guarantor to comply, at all 
times with all Environmental Laws and all other federal, state or local 
statutes, laws, ordinances, rules, regulations, orders or decrees relating 
to Environmental Laws.

     5.11 Debt Service Coverage Ratio.  Borrower shall maintain a Debt 
          ---------------------------
Service Coverage Ratio of at least 1.25:1.00 as of the end of each calendar
year, which ratio shall be calculated using Borrower's consolidated 
financial statements.  For purposes hereof, the "Debt Service Coverage 
Ratio" shall be calculated at the end of each calendar year, and shall 
mean the ratio of (1) the sum of (a) the net income (or loss) of Borrower, 
less dividends, plus (b) interest expense on Indebtedness (including the 
Obligations), plus (c) depreciation expenses, plus (d) amortization expense,
minus (e) dividends, to (2) the sum of (a) current maturities of long
term debt, plus (b) interest expense, all determined in accordance with GAAP.

     5.12 Current Ratio.  The Borrower shall maintain a Current Ratio of 
          -------------
at least 1.5:1 at all times.  For purposes hereof, the term "Current Ratio"
shall be defined as the ratio of Current Assets to Current Liabilities, as 
such terms are defined in accordance with GAAP.  Although the Borrower shall
be required at all times to comply with this Section 5.12, the Lender shall
test the Borrower's compliance on a quarterly basis using the consolidated 
financial statements and other information provided by Borrower.

     5.13 Capital Funds.  The Borrower shall at all times maintain Capital 
          -------------
Funds in an amount equal to or in excess of $3,500,000.  Although the

the consolidated financial statements and other information provided by
Borrower.

the consolidated financial statements and other information provided by
Borrower.

          -------------------
of Default, the Lender shall have, in addition to all other rights and 
remedies which the Lender may have under this Agreement, the other Loan 
Documents, and applicable law, the following rights and remedies, all of 
which may be exercised with or without further notice to the Borrower: 
(a) all of the rights and remedies of a secured party under the UCC of the 
State of Florida, or any other state where such rights and remedies are 
asserted; (b) the right to foreclose the Liens created under the Loan 
Documents or under any other agreement relating to the Collateral, by any 
available judicial procedure or without judicial process; (c) the right to 
the fullest extent allowed by law, to enter any premises where the 
Collateral may be located, through self-help and without judicial process, 
without first obtaining a final judgment or giving the Borrower notice and 
opportunity for a hearing on the validity of the Lender's claim, for the 
purpose of taking possession or removing the same, or require the Borrower 
to assemble the Collateral and make it available to the Lender at a place 
to be designated by the Lender; and/or (d) the right to exercise any or all 
of the remedies available to Lender (whether pursuant to the Loan Documents 
or otherwise available at law or in equity).  The Borrower agrees that the 
Lender has no obligation to preserve rights to the Collateral against any 
Person or to marshall any Collateral for the benefit of any Person. 

     8.2  Rights and Remedies Cumulative; Non-Waiver; Etc.  The enumeration
          -----------------------------------------------

intended to be exhaustive and the exercise by the Lender of any right or 
remedy shall not preclude the exercise of any other rights or remedies, all 
of which shall be cumulative, and shall be in addition to any other right
or remedy given hereunder, under the Loan Documents or under any other 
agreement between the Borrower and the Lender or which may now or hereafter
exist in law or in equity or by suit or otherwise.  No delay or failure to 
take action on the part of the Lender in exercising any right, power or 
privilege shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right, power or privilege preclude other or further 
exercise thereof or the exercise of any other right, power or privilege or 
shall be construed to be a waiver of any Event of Default.  No course of 
dealing between the Borrower and the Lender or the Lender's employees shall 
be effective to change, modify or discharge any provision of this Agreement 
or to constitute a waiver of any Event of Default.  The Lender shall not, 
under any circumstances or in any event whatsoever, have any liability for 
any error, omission or delay of any kind occurring in the 

<PAGE>

liquidation of the Collateral or for any damages resulting therefrom except
damages directly attributable to the Lender's gross negligence or willful 
misconduct.

     SECTION 9.  PAYMENT OF EXPENSES.

     Whether or not the transactions contemplated by this Agreement shall 
be consummated, the Borrower will:

     9.1  Fees and Expenses.  Pay or reimburse the Lender upon demand for

paralegals' expenses and travel expenses) incurred or paid by the Lender

the Revolver Loan Agreement shall not exceed $6,000, exclusive of title 
insurance premiums, long distance telephone charges, photocopying expense, 
delivery charges and other disbursements); (b) charges for appraisers,

action (whether instituted by the Lender or the Borrower or any other 
Person) in any way relating to the Collateral, this Agreement or the other 
Loan Documents, or the Loan; (d) any attempt to enforce any rights of the 
Lender or any participant against the Borrower or any other Person which 
may be obligated to the Lender by virtue of this Agreement or the other 
Loan Documents; (e) any attempt to inspect, evaluate, verify, protect, 
collect, sell, liquidate or otherwise dispose of the Collateral; and

connection with the transactions contemplated by this Agreement or the Loan
Documents or in any modification hereof or thereof. 

     9.3  Brokerage Fees.  Indemnify and hold the Lender harmless from 
          --------------
and against any and all finder's or brokerage fees and commissions which 
may be payable in connection with the transactions contemplated by this 
Agreement other than any fees or commissions of finders or brokers engaged 
by the Lender.

     SECTION 10. MISCELLANEOUS.

     10.1  Survival of Agreements.  All agreements, covenants, representa-
           ----------------------
tions and warranties contained herein or made in writing by or on behalf 
of the Borrower in connection with the 

<PAGE>

transactions contemplated hereby shall survive the execution and delivery 
of this Agreement and the other Loan Documents until the Obligations are 
fully paid and performed and Lender shall have no further obligations under
this Agreement.  No termination or cancellation (regardless of cause or 
procedure) of this Agreement shall in any way affect or impair the powers, 
obligations, duties, rights and liabilities of the parties hereto in any 
way with respect to any transaction or event occurring prior to such 
termination or cancellation.  The Borrower further agrees that to the 
extent that the Borrower makes a payment or payments to the Lender, which 
payment or payments or any part thereof are subsequently invalidated, 
declared to be fraudulent or preferential, set aside and/or required to 
be repaid to a trustee, receiver or any other party under any bankruptcy, 
insolvency or similar state or federal law, common law or equitable cause, 
then, to the extent of such payment or repayment, the obligation or part 
thereof intended to be satisfied shall be revived and continued in full 
force and effect as if such payment had not been received by the Lender.

     10.2  Governing Law; Waiver of Jury Trial.  THIS AGREEMENT SHALL BE
           -----------------------------------
INTERPRETED, AND THE RIGHTS AND LIABILITIES OF THE PARTIES HERETO DETER-

AFFECT THE RIGHT OF THE LENDER TO BRING ANY ACTION OR PROCEEDING AGAINST 
THE BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH

     10.4 Indemnification of the Lender and its Affiliates.  From and at 
          ------------------------------------------------
all times after the date of this Agreement, and in addition to all of the 
Lender's other rights and remedies against the Borrower, the Borrower 
agrees to hold the Lender its Affiliates and their respective officers,
directors and employees, harmless from, and to indemnify the Lender, its 
Affiliates and their respective officers, directors and employees against, 
all losses, damages, costs and expenses (including, but not limited to, 
attorneys' and paralegals' fees, costs and expenses) incurred by the 
Lender, its Affiliates and their respective officers, directors and 
employees from and after the date hereof, whether direct, indirect or 
consequential, as a result of or arising from or relating to any suit, 
action or proceeding by any Person, whether threatened or initiated, 
asserting a claim for 

<PAGE>

any legal or equitable remedy against any Person under any statute or 
regulation, including, but not limited to, any federal or state securities 
laws, or under any common law or equitable cause or otherwise, arising from
or in connection with the negotiation, preparation, execution or performance
of, or the financing transactions contemplated by, this Agreement and the 
other Loan Documents, the Lender's furnishing of funds to the Borrower 
pursuant to this Agreement; provided, however, that the foregoing indemni-
fication shall not protect a Lender or its Affiliates from loss, damage, 
cost or expense directly attributable to such Lender's or any Affiliate's 
willful misconduct or gross negligence.  All of the foregoing losses, 
damages, costs and expenses of the Lender, its Affiliates and their re-
spective officers, directors and employees shall be payable by the Borrower
upon demand by the Lender and shall be additional Obligations hereunder 
secured by the Collateral.

     10.5  Waivers by the Borrower.  Except as otherwise provided for in 
           -----------------------
this Agreement, the Borrower waives (a) presentment, demand and protest 
and notice of presentment, protest, non-payment, maturity and all other 
notices; (b) notice prior to taking possession or control of the Collateral
or any bond or security which might be required by any court prior to 
allowing the Lender to exercise any of the its remedies; and (c) the 
benefit of all valuation, appraisement and exemption laws.

     10.6  Lawful Charges.  It is the intent of the parties that the rate 
           --------------
of interest and all other charges due from the Borrower be lawful.  Not-
withstanding anything to the contrary contained in this Agreement or the 
Note, if at any time until payment in full of the obligations, the rate
of interest payable with respect to the Loan (the "Stated Rate") exceeds 
the highest lawful rate permissible under any law which a court of 
competent jurisdiction shall, in a final determination, deem applicable 
hereto (the "Maximum Lawful Rate"), then in such event and so long as the
Maximum Lawful Rate would be so exceeded, the Stated Rate shall be equal 
to the Maximum Lawful Rate; provided, however, that if at any time there-
after the Stated Rate is less than the Maximum Lawful Rate, the Borrower 
shall continue to pay interest hereunder at the Maximum Lawful Rate until 
such time as the total interest received by the Lender from the making of 
Loan hereunder is equal to the total interest which the Lender would have 
received had the Stated Rate been (but for the operation of this paragraph)
the interest rate payable since the Closing Date. Thereafter, the interest 
rate payable hereunder shall be the Stated Rate unless and until the Stated
Rate again exceeds the Maximum Lawful Rate, in which event this paragraph 
shall again apply. In no event shall the total interest received by the 
Lender pursuant to the terms hereof exceed the amount which the Lender 
could lawfully have received had the interest due hereunder been calculated
for the full Term at the Maximum Lawful Rate.  If for any reason payment of 
a portion of interest or charges as required by this Agreement would exceed
the limit established by applicable law, then the obligation to pay 
interest or charges shall automatically be reduced to such limit and if 
any amounts in excess of such limit shall have been paid, then such amounts
shall be applied to the unpaid principal amount of the Obligations or 
refunded so that under no circumstances shall interest or charges required 
hereunder exceed the maximum rate allowed by law.

<PAGE>

     10.7  Assignment.  The Borrower may not sell, assign or transfer this 
           ----------
Agreement, or the other Loan Documents or any portion thereof, including 
without limitation, the Borrower's rights, title, interests, remedies, 
powers, and duties hereunder or thereunder.  The Borrower hereby consents 
to the Lender's participation, sale, assignment, transfer or other disposi-
tion at any time or times hereafter of this Agreement or the other Loan 
Documents, or of any portion hereof or thereof, including without limita-
tion, the Lender's rights, title, interests, remedies, powers and duties 
hereunder or thereunder.

     10.8  Amendment.  This Agreement and the other Loan Documents cannot 
           ---------
be amended, changed, discharged or terminated orally, but only by an instru-
ment in writing signed by the Lender and the Borrower.

     10.9  Severability.  To the extent any provision of this agreement is 
           ------------
prohibited by or invalid under applicable law, such provision shall be 
ineffective to the extent of such prohibition or invalidity, without 
invalidating the remainder of such provision or the remaining provisions
of this Agreement.

     10.10 Entire Agreement.  This Agreement and the other documents, 
           ----------------
certificates and instruments referred to herein constitute the entire 
agreement between the parties and supersede and rescind any prior agree-
ments relating to the subject matter hereof.

     10.11 Binding Effect.  All of the terms of this Agreement and the 
           --------------
other Loan Documents, as the same may from time to time be amended, shall 
be binding upon, inure to the benefit of and be enforceable by the respec-
tive successors and assigns of the Borrower and the Lender.  This pro-
vision, however, shall not be deemed to modify Section 10.7.

     10.12 Captions.  The captions to the various sections and subsections 
           --------
of this Agreement have been inserted for convenience only and shall not 
limit or affect any of the terms hereof.

     10.13 Disbursement of Loan Proceeds.  The Borrower hereby authorizes 
           -----------------------------
and directs the Lender to disburse, for and on behalf of the Borrower and 
for the Borrower's account, the proceeds of Loan made by the Lender to the 
Borrower pursuant to this Agreement to such Person or Persons as the 
Borrower shall direct, whether in writing or orally.

     10.14 Injunctive Relief.  The Borrower recognizes that in the event 
           -----------------
the Borrower fails to perform, observe or discharge any of its obligations 
or liabilities under this Agreement, any remedy of law may prove to be 
inadequate relief to the Lender.  The Borrower therefore agrees that the 
Lender, if the Lender so requests, shall be entitled to temporary and 
permanent injunctive relief in any such case without the necessity of 
proving actual damages.

     For value received, TECHDYNE, INC., a Florida corporation (together 
with its successors, legal representatives and assigns, the "Maker") 
promises to pay to the order of BARNETT BANK, N.A., a national banking 
association (such banking association, its successors and assigns, and all
successor holders of this Note are referred to herein as the "Payee"), at 
101 Hialeah Drive, 2nd Floor, Hialeah, Florida 33010 or at such other place 
as Payee may from time to time hereafter direct in writing, in legal tender 
of the United States of America, the principal sum of ONE MILLION FIVE 
HUNDRED THOUSAND AND NO/100 DOLLARS ($1,500,000.00) or so much as may be 
advanced hereunder, with interest on the principal balance outstanding 
hereunder from time to time at the rates provided below, with such 
principal and interest under this Note shall to be due and payable as 
provided in Section 3 below.

     1.   Definitions.
          -----------

     In addition to other defined terms used in this Note, the following 
terms shall have the meanings set forth below:

          "Adjusted Libor Rate" for each Interest Period shall mean a 
           -------------------
     daily rate that is equal the applicable Libor Rate plus the Applica-
     ble Margin.
 
          "Applicable Margin" shall mean 225 basis points.
           -----------------

          "Business Banking Day" shall mean each day other than a Saturday,
           --------------------
     a Sunday or any holiday on which commercial banks in Jacksonville, 
     Florida, are closed for business. 

          "Interest Period" shall mean each period commencing on each 
           ---------------
     Interest Rate Adjustment Date and ending on the next Interest Rate 
     Adjustment Date. 

          "Interest Rate Adjustment Date" shall mean the first day of 
           -----------------------------
     January, 1997, and the first day of every one-month period thereafter. 

          "Libor Rate" for each Interest Period shall mean the offered 
           ----------
     rate for deposits in United States dollars in the London Interbank 
     market for a one-month period which appears on the Libor Rate 
     Reference Page as of 11:00 a.m. (London time) on the day that is 
     two London Banking Days preceding the first Business Banking Day
     of the Interest Period, adjusted for reserves by dividing that rate 
     by 1.00 minus the Reserve Requirement.  If at least two such offered 
     rates appear on the Libor Rate Reference Page, the rate will be the 
     arithmetic mean of such offered rates adjusted for reserves as afore-
     said.  At Payee's option, the Payee may elect at any time during
     the term of this Note not to adjust the Libor Rate for reserves.  
     However, the election of the Payee not to adjust the Libor Rate for 
     reserves shall not constitute a waiver of the Payee's right to do so 
     prospectively at any time thereafter.  Maker hereby expressly agrees 
     that at any time any principal amount is outstanding hereunder, the 

<PAGE>

     Payee shall be entitled to thereafter adjust the Libor Rate for 
     reserves in determining the Adjusted Libor Rate, notwithstanding 
     the failure of Payee to do so at any prior time.  The Payee may, in 
     its sole discretion, use rate quotations for daily or annual periods 
     in lieu of quotations for substantially equivalent monthly periods.

          "Libor Rate Reference Page" shall mean either (a) the Reuters 
           -------------------------
     Screen LIBO Page, (b) the Dow Jones Telerate Page 3750, or (c) such 
     other nationally recognized source, as any at the foregoing may from 
     time to time be used by Payee in its sole discretion as a reference 
     for determining any applicable Libor Rate. 

          "Loan Agreement" shall mean the Loan Agreement of even date 
           --------------
     hereunder between Maker and Payee, as shall agreement may be modified 
     or amended from time to time.

          "Loan Documents" shall mean this Note, the Loan Agreement, the 
           --------------
     Security Agreement and all other documents now or hereafter evi-
     dencing, securing, guarantying or otherwise relating to the indebted-
     ness evidenced by this Note or any portion thereof, as such documents 
     may be modified or amended from time to time.

          "London Banking Day" shall mean each day other than a Saturday, 
           ------------------
     a Sunday or any holiday on which commercial banks in London, England 
     are closed for business. 

          "Maturity Date" means December 29, 2002.
           -------------

          "Prime Rate" shall mean the annual rate of interest announced 
           ----------
     from time to time by Barnett Banks, Inc., or its successor, as its 
     prime rate of interest, subject to change on a daily basis.  Should 
     Barnett Banks, Inc. or its successor at any time not announce a prime 
     rate, the Payee in its reasonable discretion, may choose a substitute 
     prime rate.  The Prime Rate is a reference rate for the information 
     and use of the Payee in establishing the actual rates to be charged 
     to its borrowers. 

          "Regulation D" shall mean Regulation D of the Board of Governors 
           ------------
     of the Federal Reserve System as from time to time in effect and any 
     successor thereto or other regulation or official interpretation of 
     said Board of Governors relating to reserve requirements applicable 
     to member banks of the Federal Reserve System.

          "Reserve Requirement" shall mean the maximum percentage require-
           -------------------
     ment (rounded to the next higher 1/100 of 1% and expressed as a 
     decimal) in effect for any day during the Interest Period, including,
     without limitation (a) any basic, supplemental, marginal or emergency
     reserves under any regulations under any governmental authority, and 
     (b) any reserves prescribed by the Board of Governors of the Federal 
     Reserve system (or any successor), including, without limitation,
     Regulation D, for determining the maximum reserve requirement for 
     "Eurocurrency liabilities" (or in respect of any other category of 
     liabilities which includes deposits by reference to which the Libor 
     Rate is determined), but without benefit or credit of proration, 
     exemptions, or offsets that might otherwise be available to the Payee
     from time to time under such regulation.  Without limiting the effect 
     of the foregoing, the Reserve Requirement shall reflect any other 
     reserves required to be maintained by the Payee against (i) any 
     category of liabilities that include deposits by reference to 

<PAGE>

     which the Libor Rate is to be determined; or (ii) any category of
     extension of credit or other assets that includes loans bearing 
     interest at a rate based on the Libor Rate.  The determination by 
     Payee of the Reserve Requirement shall be conclusive and binding. 

          "Security Agreement" shall mean the Commercial Security Agreement
           ------------------
     of even date herewith between Maker and Payee, as shall agreement 
     may be modified or amended from time to time.

          "Swap Agreements" shall mean, collectively, an ISDA Master 
           ---------------
     Agreement dated as of December 22, 1997, between Maker and Payee, any 
     other or additional swap agreements (as defined in 11 U.S.C. 101) 
     between Maker and Payee or any of its affiliates, and all other 
     interest rate swap documents, whether now or hereafter existing, 
     between Maker and Payee or any of its affiliates.

     2.   Interest.
          --------

          (a)  Interest shall initially accrue on the outstanding principal
balance of this Note at a rate of 8.21875% per annum, but the rate of 
interest shall be adjusted on each Interest Rate Adjustment Date so that 
interest shall accrue at the Adjusted Libor Rate for the Interest Period
commencing on such Interest Rate Adjustment Date.  Notwithstanding anything
to the contrary provided in this Note, (i) the non-default rate under this 
Note shall be subject to the provisions of Section 2(d) below, and (ii) 
from and after the occurrence of any default under this Note or any 
document executed in connection herewith, the entire unpaid principal 
balance under this Note shall bear interest at the Default Rate as pro-
vided in Section 9 below.  Interest on this Note shall be calculated on 
the basis of a 360-day year and the actual number of days elapsed (i.e., 
interest for each day any principal is outstanding shall be computed at 
the annual rate divided by 360); provided, however, that interest at the 
Default Rate shall be calculated on the basis of a 365 or 366, day year, 
as applicable.

          (b)  If Payee determines that the maintenance of any Adjusted 
Libor Rate would violate any applicable law, rule, regulation, or direc-
tive, whether or not having the force of law, or if the Payee determines 
the Adjusted Libor Rate does not accurately reflect the cost of maintaining
the loan evidenced by this Note, then, at the election of Payee, the non-
default interest rate applicable to the principal amount outstanding under 
this Note shall thereafter be adjusted to such interest rate as may be 
determined by Payee.  Such interest rate shall be based upon such substi-
tute, but reasonably comparable index as may be selected by Payee.

     3.   Payments.
          --------

     Accrued interest on the principal sum outstanding hereunder shall be 
due and payable monthly, commencing on the fifteenth (15th) day of the 
first calendar month immediately following the date hereof, and on the 
fifteenth (15th) day of each calendar month thereafter through the 
Maturity Date.  In addition to such monthly interest payments, Maker 
shall pay to Payee, commencing on the fifteenth (15th) day of the first 
calendar month immediately following the date hereof, and on fifteenth 
(15th) day of each calendar month thereafter through the Maturity Date,
a monthly principal payment of $25,000.00.  Subject to the rights of 
Payee under Section 8 below to accelerate the maturity of this Note, 
all outstanding principal, all accrued but unpaid interest, and all other 
sums payable under or in connection with this Note shall be due and payable
on the Maturity Date.

<PAGE>

     4.  Manner of Payment.
         -----------------

     All payments hereunder shall be made in immediately available funds 
on or before 2:00 pm (Miami time) on the due date thereof and such payments
shall be made in lawful money of the United States of America.  Maker shall
not be entitled to any deduction, deferment, suspension, set-off, defense 
or counter-claim in respect of any principal, interest or other sums due 
under this Note.  

     5.   Prepayment.  
          ----------

     The principal amount outstanding under this Note may be prepaid in 
whole or in part upon ten (10) days written notice to Payee only upon the 
last day of any Interest Period.  Any partial prepayments shall be applied 
to the principal amounts due under this Note in the inverse order of 
maturity.  Any prepayment in full must be accompanied by payment in full 
of all accrued but unpaid interest and all other sums payable under this 
Note and all other Loan Documents.  The prepayment of this Note shall not 
limit, release or otherwise affect the liability of Maker under the Swap 
Agreements.

     6.   Application of Payments.
          -----------------------

     Prior to the occurrence of any default under this Note, all payments 
hereunder shall first be applied to interest and then to principal.  Upon 
the occurrence of any default under this Note, all payments hereunder shall
be applied to interest, principal, costs and expenses of Payee, and/or any
other sums payable under or in connection with this Note, in such manner 
as the Payee may elect in its sole and absolute discretion.

     7.   Late Charges.
          ------------

     In the event that any payment due under this Note is not received 
by Payee on or before 10 days after the due date thereof, Maker must pay 
to Payee a late charge of five percent (5%) of the amount of such payment.
The right to collect a late charge shall be in addition to all other rights
and remedies of Payee under or in connection with the loan evidenced hereby,
including the right to accelerate the entire balance outstanding under this
Note as a result of the Maker's default.  The Maker agrees that such late 
charge is a fair and reasonable charge for the increased administrative 
costs incurred in connection with handling late payments and is not a 
penalty.  
     
     8.   Default.
          -------

     If any principal, interest or other sum payable hereunder or any of 
the other Loan Documents is not paid on the due date thereof, if all out-
standing unpaid principal, all accrued but unpaid interest, and all other 
sums payable under this Note or the other Loan Documents are not paid in 
full on the Maturity Date, if Maker shall default in the performance or 
observance of the covenants contained in the Loan Agreement, if Maker or 
any endorser or guarantor of this Note shall die or become insolvent 
(however such insolvency may be evidenced) or shall file a voluntary
bankruptcy petition or be the subject of an involuntary bankruptcy 
petition, or if the Maker or any guarantor shall make a general assign-
ment for the benefit of creditors, or if the Maker shall suspend the 
transaction of its usual business, or if there is a material change in 
the financial condition of the Maker or any guarantor, or if any default 
or event of default shall occur under the Loan Agreement, any Swap 
Agreement, or other Loan Documents (after taking into consideration all
applicable cure periods), or if Maker shall default in the payment of any 
other indebtedness or liability of any kind whatsoever now or hereafter 
due from Maker to Payee, then this Note shall be deemed to be in 

<PAGE>

default and all principal, interest and other sums payable hereunder shall 
at the option of the Payee become and be due and payable forthwith, without
presentation, demand, protest, notice of protest, or any other notice of 
dishonor of any kind, all of which are hereby expressly waived. 

     9.   Default Rate.
          ------------

     Notwithstanding anything to the contrary provided herein, from and 
after the occurrence of any default under this Note, the Loan Agreement, 
or any of the Loan Documents, the entire principal amount outstanding 
under this Note shall bear interest (regardless of whether or not the 
maturity of this Note is accelerated as a result of the default) at a 
rate (the "Default Rate") equal to the highest rate permitted under then 
applicable law, but if no such highest rate is established by applicable 
law, or in the event the highest rate is otherwise indeterminable, the 
Default Rate shall be equal to, and the entire principal balance shall 
bear interest at the rate of, the Adjusted Libor Rate plus 5% per annum.

     10.  Legal Rate of Interest.
          ----------------------

     It is the intent of the parties hereto that in no event shall any 
interest or payment in the nature of the interest under this Note exceed 
the maximum rate of interest allowed by applicable law, as amended from 
time to time, and in the event any such payment is paid by the Maker or
received by the Payee, then such excess sum shall be credited as a pay-
ment of principal, unless the Maker shall notify the Payee, in writing, 
that the Maker elects to have such excess sum returned to it forthwith.  
The Payee may, in determining the maximum rate of interest allowed under
applicable law, as amended from time to time, take advantage of any law, 
rule or regulation in effect from time to time and available to the Payee 
which exempts the Payee from any limit upon the rate of interest it may 
charge or grants to the Payee the right to charge a higher rate of interest
than that allowed by Chapter 687, Florida Statutes.  Without limiting the 
generality of the foregoing, Payee shall, to the fullest extent allowable, 
be entitled to charge and collect interest at the rate allowed by Chapters 
656 and 665, Florida Statutes.

     11.  Presentment, Extensions, Substitutions, Etc.
          -------------------------------------------

     Maker and all others who are or may become liable for the payment 
hereof severally, to the fullest extent allowed by law, hereby:  (a) waive 
presentment for payment, demand, notice of demand, notice of non-payment, 
or dishonor, protest and notice of protest of this Note, and all other 
notices in connection with the delivery, acceptance, performance, default, 
or enforcement of the payment of this Note, (b) consent to all extensions 
of time, renewals, postponements of time of payment of this Note or other 
modifications hereof that may be granted by Payee from time to time, both 
prior to or after the maturity date hereof (whether by acceleration or in 
due course), without the necessity of notice, consent or consideration to 
the Maker or any others who are or may become liable for payment of this 
Note, (c) agree that Payee may accept, substitute, exchange, add, or 
release any security for the indebtedness evidenced by this Note or add or 
release any party or person primarily or secondarily liable hereon, without
the necessity of notice, consent or consideration, (d) agree that the Payee
shall not be required first to institute any suit, or to exhaust its 
remedies against the Maker or any other person or entity liable or to 
become liable hereunder or against any security for this Note in order 
to enforce the payment of this Note against any person now or hereafter 
liable for the payment hereof, (e) agree that, notwithstanding the occur-
rence of any of the foregoing, they shall be and remain jointly and 
severally, directly and primarily liable for all sums due under this 
Note (unless the Payee has specifically and expressly released such party
in a written document executed by an authorized officer of Payee, provided 
that any such release shall not release any other 

<PAGE>

persons or entities not thereby expressly and specifically released), and 
(f) waive all applicable exemption rights (whether under the state consti-
tution or otherwise).

     12.  Venue, Jurisdiction.
          -------------------

     The Maker and all others who are, or who may become, liable for the
 payment hereof severally, irrevocably and unconditionally (a) agree that 
any suit, action or other legal proceeding arising out of, under or 
relating to this Note may be brought, at the option of the Payee in a court
of record of the State of Florida in Dade County, Florida, in the United 
States District Court for the Southern District of Florida, or in any 
other court of competent jurisdiction; (b) consent to the jurisdiction of 
each such Court in any such suit, action or proceeding; and (c) waive any 
objection which it or they may have to the laying of venue of any such suit,
action, or proceeding in any of such courts.  

     13.  Governing Law.
          -------------

     This Note shall be construed, interpreted, enforced and governed by 
and in accordance with the laws of the State of Florida (excluding the 
principles thereof governing conflicts of law), and to the extent appli-
cable, federal law.

     14.  Severability.
          ------------

     If any provision or portion of this Note is declared or found by a 
court of competent jurisdiction to be unenforceable or null and void, such 
provision or portion thereof shall be deemed stricken and severed from 
this Note, and the remaining provisions and portions thereof shall continue
in full force and effect.

     15.  Written Modification or Waiver Only.
          -----------------------------------

     This Note may not be amended, extended, or modified except by an 
instrument in writing executed by an authorized officer of the Payee.  
No waiver of any of the provisions of this Note shall be effective unless 
such waiver is contained in a written instrument executed by an authorized
officer of Payee.  Any waiver of any provision hereof shall be effective 
only in the specific instance and for the specific purpose for which given.

     16.  Time of the Essence; Miscellaneous.
          ----------------------------------

     Time is of the essence hereof with respect to all provisions of this 
Note.  The use of the words "herein", "hereof", "hereunder" and any other

after withholding or deduction for or on account of any such present or 
future taxes, duties or charges, will not be less than the amount provided

are, or who may become liable for the payment hereof, severally expressly 
grant to the Payee a continuing first-lien security interest in any and 
all money, general or specific deposits, or property of any such parties
now or hereafter in the possession of the Payee.  The Maker and such other 
parties authorize and empower the Payee, in its sole discretion, at any

money, deposits or property to the payment hereof or to the payment of 
any and all indebtedness, liabilities and obligations of such parties to

2.   OBLIGATIONS OF GRANTOR. Grantor warrants and covenants to Lender as

     (a)  No Merger; Name Change, Etc.  Except as disclosed in writing 
     delivered to Lender; (i) no entity has merged into Grantor or been 
     consolidated, with Grantor, and Grantor's business structure and 
     entity has not changed; (ii) no entity has sold substantially all of 
     its assets to Grantor or sold assets to Grantor outside the ordinary 
     course of such seller's business at anytime in the past; and (iii) 
     Grantor has not changed its name or identity or used any new trade 
     name or merged or consolidated with any other entity.

     (b)  Taxes.  All assessments and taxes, whether real, personal, or 
     otherwise, due or payable by, or imposed, levied, or assessed against 
     Grantor or any of its property have been paid in full before delin-
     quency or before the expiration of any extension period; and Grantor 
     has made due and timely payment or deposit of all federal, state, and 
     local taxes, assessments, or contributions required of it by law, 
     except only for items that Grantor is currently contesting diligently 
     and in good faith and that have been fully disclosed in writing to 
     Lender.

     (c)  Perfection of Security Interest. Grantor agrees to execute such 
     financing statements and to take whatever other actions are requested 
     by Lender to further grant, to perfect and to continue Lender's 
     security interest in the Collateral. Upon request of Lender, Grantor 
     will deliver to Lender any and all of the documents evidencing or 
     constituting the Collateral, and Grantor will note Lender's interest 
     upon any and all chattel paper if not delivered to Lender for posses-
     sion by Lender.  Grantor hereby makes, constitutes and appoints Lender
     as its irrevocable true and lawful attorney-in-fact for the purpose 
     of executing any documents necessary to perfect or to continue the 
     security interest granted in this Agreement. Any person dealing with 
     Grantor shall be entitled to rely conclusively on any written or oral
     statement of Lender that this power of attorney is in effect. Lender 
     may at any time, and without further authorization from Grantor, file 
     a carbon, photographic or other reproduction of any financing statement
     or of this Agreement for use as a financing statement. Grantor will 
     reimburse Lender for all expenses for the perfection and the continua-
     tion of the perfection of Lender's security interest in the Collateral.
     Grantor promptly will notify Lender of any change in Grantor's name 
     including any change to the assumed business names of Grantor. This 
     is a continuing Security Agreement and will continue in effect even 
     though all or any part of the Indebtedness is paid in full and even 
     though for a period of time Grantor may not be indebted to Lender.

<PAGE>

     (d)  No Violation. The execution and delivery of this Agreement will 
     not violate any law or agreement governing Grantor or to which Grantor
     is a party, and its certificate or articles of incorporation and 
     bylaws do not prohibit any term or condition of this Agreement.

     (e)  Enforceability of Collateral. To the extent the Collateral con-
     sists of accounts, contract rights, chattel paper, or general intan-
     gibles, the Collateral is enforceable in accordance with its terms, 
     is genuine, and complies with applicable laws concerning form, content 
     and manner of preparation and execution, and all persons appearing to 
     be obligated on the Collateral have authority and capacity to contract
     and are in fact obligated as they appear to be on the Collateral. At 
     the time any account becomes subject to a security interest in favor 
     of Lender, the account shall be a good and valid account representing 
     an undisputed, bona fide indebtedness incurred by the account debtor, 
     for merchandise held subject to delivery instructions or theretofore 
     shipped or delivered pursuant to a contract of sale, or for services 
     theretofore performed by Grantor with or for the account debtor; there
     shall be no setoffs or counterclaims against any such account; no 
     agreement under which any deductions or discounts may be claimed shall
     have been made with the account debtor except those disclosed to Lender
     in writing.

     (f)  Aging Reports. Unless otherwise waives or modified in writing by
     Lender, Grantor shall from time to time hereafter, but not less 
     frequently than quarterly, execute and deliver to Lender, a detailed 
     aging of accounts by total, a summary aging of accounts by account 
     debtor, a reconciliation statement, and an accounts payable schedule. 

     (g)  Records.  Grantor will keep or will cause to be kept, accurate 
     and complete records of the accounts and will deliver such records and
     other financial information to Lender as are requested, and that Lender
     or its designee shall have the right at any time upon request to call 
     Grantors place(s) of business at intervals solely determined by Lender,
     and without hindrance or delay, inspect, audit, make test verifica-
     tions, send verification of an account to any account debtor and 
     otherwise check and make copies of books, records, journals, orders, 
     receipts, correspondence and other data related to the accounts or 
     the processing or collection thereof.

     (h)  Instruments.  If any account shall be evidenced by a promissory 
     note, trade acceptance or any other instrument for the payment of 
     money, Grantor upon Lender's request, will promptly deliver same to 
     Lender, properly endorsed to Lender's order. Regardless of the form 
     of such endorsement, Grantor hereby waives presentment, demand, 
     notice of dishonor, protest and notice of protest and all other 
     notices to which Grantor might be entitled. 

     (i)  Inventory Reports. To the extent the Collateral consists of in-
     ventory, unless otherwise waived or modified in writing by Lender, 
     Grantor shall from time to time but not less than quarterly execute 
     and deliver to Lender no later than the 15th day of each quarter 
     during the term of this Agreement an inventory report, acceptable 
     to Lender specifying Grantor's cost and the resale price of Grantor's
     raw materials, work in process, and finished goods and such other 
     information as Lender may reasonably request.

     (j)  Removal of Collateral. Grantor shall keep the Collateral (or to 
     the extent the Collateral consists of intangible property such as 
     accounts, the records concerning the Collateral) at the locations 
     identified in Exhibit "A" attached hereto or at such other locations 
     as are acceptable to Lender. Except in the ordinary course of its 
     business, including the sale of inventory, Grantor shall not remove 
     the Collateral from its existing locations without the prior written 
     consent of Lender.  To the extent that the Collateral consists of 
     vehicles, or other titled property Grantor shall not take or permit 
     any action which would require application for certificates of title 
     for the vehicles outside the State of Florida, without the prior 
     written consent of Lender.

     (k)  Transactions Involving Collateral. Except for inventory sold or 
     accounts collected in the ordinary course of Grantor's business, 
     Grantor shall not sell, offer to sell, consign or otherwise transfer 
     or dispose of the Collateral. While Grantor is not in default under 
     this Agreement, Grantor may sell inventory, but only in the ordinary 
     course of its business and only to buyers who qualify as a buyer in 
     the ordinary course of business. A sale in the ordinary course of 
     Grantor's business does not include a transfer in partial or total 
     satisfaction of a debt or any bulk sale. Grantor shall not pledge, 
     mortgage, encumber or otherwise permit the Collateral to be subject 
     to any lien, security interest, encumbrance, or charge, other than 
     the security interest provided for in this Agreement, without the 
     prior written consent of Lender. This includes security interests 
     even if junior in right to the security interests granted under this 
     Agreement. Unless waived by Lender, all proceeds from any disposition 
     of the Collateral (for whatever reason) shall be held in trust for 
     Lender and shall not be commingled with any other funds; provided 
     however, this requirement shall not constitute consent by Lender to 
     any sale or other disposition. Upon receipt, Grantor shall immediately
     deliver any such proceeds to Lender.

     (l)  Title.  Grantor represents and warrants to Lender that it holds 
     good and marketable title to the Collateral, free and clear of all 
     liens and encumbrances except for the lien of this Agreement. No 
     financing statement covering any of the Collateral is on file in any 
     public office other than those which reflect the security interest 
     created by this Agreement or to which Lender has specifically 
     consented. Grantor shall defend Lender's rights in the Collateral 
     against the claims and demands of all other persons. Upon Lender's 
     request, if Grantor now or hereafter has any vehicle or equipment for 
     which a certificate of title has been or will be issued, Grantor shall
     immediately deliver to Lender, properly endorsed, each certificate of 
     title for such vehicle or equipment for the lien of Lender to be 
     recorded.

<PAGE>

     (m)  Maintenance and Inspection of Collateral. Grantor shall maintain 
     all tangible Collateral in good operating condition and make all 
     necessary repairs to preserve the Collateral's value. Grantor will 
     not commit or permit damage to or destruction of the Collateral or 
     any part of the Collateral. Lender and its designated representatives 
     and agents shall have the right at all reasonable times to examine, 
     inspect, test, and audit the Collateral wherever located.

     (n)  Notice. At least thirty (30) days prior to the occurrence of any 
     of the following events, Grantor will deliver to Lender written notice
     of such impending events:  (i) any addition, deletion or a change in 
     Grantor's place(s) of business and/or the location(s) of the Col-
     lateral; or (ii) any addition, deletion or change in Grantor's name,
     any doing business as name, trade name, fictitious name, identity or 
     legal structure.

     (o)  Taxes, Assessments and Liens. Grantor will pay when due all 
     taxes, assessments and liens upon it and the Collateral, its use or 
     operation, upon this Agreement, upon any promissory note or notes 
     evidencing the Indebtedness, or upon any of the other Related Docu-
     ments. Grantor may withhold any such payment or may elect to contest 
     any lien if Grantor is in good faith conducting an appropriate pro-
     ceeding to contest the obligation to pay and so long as Lender's 
     interest in the Collateral is not jeopardized in Lender's sole 
     opinion. If the Collateral is subjected to a lien which is not dis-
     charged within thirty (30) days, Grantor shall deposit with Lender 
     cash, a sufficient corporate surety bond or other security satisfac-
     tory to Lender in an amount adequate to provide for the discharge of 
     the lien plus any interest, costs, reasonable attorneys' fees or 
     other charges that could accrue as a result of foreclosure or sale. 
     Grantor will, in the event of appropriation or taking of all or any 
     part of the Collateral, give Lender prompt written notice thereof. 
     Lender shall be entitled to receive directly, and Grantor shall 
     promptly pay over to Lender, any awards or other amounts payable with
     respect to such condemnation, requisition or other taking and in its 
     sole discretion may apply the proceeds as it deems best without regard
     to if an Event of Default has or has not occurred.

     (p)  Accounting System. Grantor at all times hereafter shall maintain 
     a consistent system of accounting, with ledger and account cards and/or
     computer tapes, disks, printouts, and records that contain information 
     pertaining to the Collateral that may from time to time be requested 
     by Lender. Grantor shall not modify or change its method of accounting
     or enter into any agreement hereafter with any third-party accounting 
     firm and/or service bureau for the preparation and/or storage of 
     Grantor's accounting records without said accounting firm's and/or 
     service bureau's agreeing to provide to Lender information regarding 
     the Collateral and Grantor's financial condition.

     (q)  Compliance With Governmental Requirements. Grantor shall comply 
     promptly with all laws, ordinances, rules and regulations of all 
     governmental authorities, now or hereafter in effect, applicable to 
     the ownership, production, disposition, or use of the Collateral. 
     Grantor may contest in good faith any such law, ordinance or regula-
     tion and withhold compliance during any proceeding, including appro-
     priate appeals, so long as Lender's interest in the Collateral, in 
     Lender's opinion, is not jeopardized.

     (r)  Collateral Value. If Lender deems the value of the Collateral to 
     be threatened by any out of the ordinary loss, dissipation, destruc-
     tion, damage or other cause, or if the Collateral is decreasing in 
     value, thereupon, or at anytime thereafter, Grantor upon demand by 
     Lender agrees to forthwith deposit with Lender, additional collateral 
     to the satisfaction of Lender.

     (s)  Hazardous Substances. The terms "hazardous waste," "hazardous 
     substance," "disposal," release," and "threatened release," as used 
     in this Agreement, shall have the same meanings as set forth in the 
     Comprehensive Environmental Response, Compensation, and Liability Act 
     of 1980, as amended, 42 U.S.C. Section 9601, et seq. ("CERCLA"), the 
     Superfund Amendments and Reauthorization Act of 1986, Pub. L. No. 
     99099 (SARA"), the Hazardous Materials Transportation Act, 49 U.S.C.
     Section 1801, et seq., the Resource Conservation and Recovery Act, 
     49 U.S.C. Section 6901, et seq., or other applicable state or Federal 
     laws, rules, or regulations adopted pursuant to any of the foregoing. 
     Except as disclosed to and acknowledged by Lender in writing, Grantor 
     represents and warrants that: (i) During the period of Grantor's 
     ownership of Grantor's properties, there has been no use, generation, 
     manufacture, storage, treatment, disposal, release or threatened 
     release of any hazardous waste or substance by any person on, under, 
     or about any of the properties. (ii) Grantor has no knowledge of, or 
     reason to believe that there has been (A) any use, generation, manu-
     facture, storage, treatment, disposal, release, or threatened release 
     of any hazardous waste or substance by any prior owners or occupants 
     of any of the properties, or (B) any actual or threatened litigation 
     or claims of any kind by any person relating to such matters; (iii) 
     Neither Grantor nor any tenant, contractor, agent or other authorized 
     user of any of the properties shall use, generate, manufacture, store,
     treat, dispose of, or release any hazardous waste or substance on, 
     under, or about any of the properties and any such activity shall be 
     conducted in compliance with all applicable federal, state, and local
     laws, regulations, and ordinances, including without limitation those 
     laws, regulations and ordinances described above. Grantor authorizes 
     Lender and its agents to enter upon the properties to make such 
     inspections and tests as Lender may deem appropriate to determine 
     compliance of the properties with this section of the Agreement. Any 
     inspections or tests made by Lender shall be for Lender's purposes 
     only and shall not be construed to create any responsibility or liabil-
     ity on the part of Lender to Grantor or to any other person.  The 
     representations and warranties contained herein are based on Grantor's
     due diligence in investigating the Collateral and the properties for 
     hazardous waste.  Grantor hereby (1) releases and waives any future 
     claims against Lender for indemnity or contribution in the event 
     Grantor becomes liable for cleanup or other costs under any such laws,
     and (2) agrees to fully and promptly pay, perform, discharge and 
     defend, indemnify and hold harmless Lender against any and all claims,
     orders, demands, causes of action, proceedings, judgments, losses, 
     liabilities, damages, penalties, and expenses which Lender may 
     directly or indirectly sustain or suffer resulting from a breach of 
     this section of this Agreement or as a consequence 

<PAGE>

     of any use, generation, manufacture, storage, disposal, release or 
     threatened release, whether occurring prior to or after Grantor's 
     ownership or interest in the properties, whether or not the same was 
     or should have been known to Grantor. The provisions of this section 
     of this Agreement, including the obligation to indemnify, shall 
     survive the payment of the Indebtedness and the satisfaction of this 
     Agreement and shall not be affected by Lender's acquisition of any 
     interest in any of the properties, whether by foreclosure or otherwise.

     (t)  Environmental Compliance and Reports. Grantor shall comply in all
     respects with all environmental protection federal, state and local 
     laws, statutes, regulations and ordinances; not cause or permit to 
     exist, as a result of an intentional or unintentional action or 
     omission on its part or on the part of any third party, on property 
     owned and/or occupied by Grantor, any environmental activity where 
     damage may result to the environment, unless such environmental 
     activity is pursuant to the conditions of a permit issued by the 
     appropriate federal, state or local governmental authorities; shall 
     furnish to Lender promptly and in any event within thirty (30) days 
     after receipt thereof a copy of any notice, summons, lien, citation, 
     directive, letter, or other communication from any governmental 
     agency or instrumentality concerning any intentional or unintentional
     action or omission on Grantor's part in connection with any environ-
     mental activity whether or not there is damage to the environment 
     and/or other natural resources.

     (u)  Maintenance of Casualty Insurance. Grantor shall procure and 
     maintain all risks insurance, including without limitation fire, theft
     and liability coverage of the kinds and in amounts customarily insured
     against by businesses in the same or similar business, together with 
     business interruption insurance and such other insurance as Lender 
     may require with respect to the Collateral, in form, coverages and 
     basis reasonably acceptable to Lender and issued by a company or 
     companies reasonably acceptable to Lender. Grantor, upon request of 
     Lender, will deliver to Lender from time to time the policies or 
     certificates of insurance in form satisfactory to Lender, including 
     stipulations that coverages will not be cancelled or diminished 
     without at least thirty (30) days' prior written notice to Lender and 
     not including any disclaimer of the insurer's liability for failure 
     to give such a notice. In connection with all policies covering assets
     in which Lender holds or is offered a security interest, Grantor will 
     provide Lender with such lender loss payable or other endorsements as 
     Lender may require. If Grantor at any time fails to obtain or maintain
     any insurance as required under this Agreement, Lender may (but shall 
     not be obligated to) obtain such insurance as Lender deems appropriate,
     including if it so chooses "single interest insurance," which will 
     cover only Lender's interest in the Collateral.

     (v)  Application of Insurance Proceeds. Grantor shall promptly notify 
     Lender of any loss or damage to the Collateral. Lender may make proof 
     of loss if Grantor fails to do so within fifteen (15) days of the 
     casualty. All proceeds of any insurance on the Collateral, including 
     accrued proceeds thereon, shall be held by Lender as part of the 
     Collateral. If Lender consents to repair or replacement of the 
     damaged or destroyed Collateral, Lender shall, upon satisfactory proof
     of expenditure, pay or reimburse Grantor from the proceeds for the 
     reasonable cost of repair or restoration. If Lender does not consent 
     to repair or replacement of the Collateral, Lender shall retain a 
     sufficient amount of the proceeds to pay all of the Indebtedness, and 
     shall pay the balance to Grantor. Any proceeds which have not been
     disbursed within six (6) months after their receipt and which Grantor 
     has not committed to the repair or restoration of the Collateral 
     shall be used to prepay the Indebtedness.

     (w)  Insurance Reports. Grantor, upon request of Lender, shall furnish
     to Lender reports on each existing policy of insurance showing such 
     information as Lender may reasonably request including the following: 
     (i) the name of the insurer; (ii) the risks insured; (iii) the amount 
     of the policy; (iv) the property insured; (v) the then current value 
     on the basis of which insurance has been obtained and the manner of 
     determining that value; and (vi) the expiration date of the policy. 
     In addition, Grantor shall upon request by Lender (however not more 
     often than annually) have an independent appraiser satisfactory to 
     Lender determine, as applicable, the cash value or replacement cost 
     of the Collateral.

3.   GRANTOR'S RIGHT TO POSSESSION. Until default, Grantor may have posses-
sion of the tangible personal property and beneficial use of all the Col-
lateral and may use it in any lawful manner not inconsistent with this 
Agreement or the Related Documents, provided that Grantor's right to 
possession and beneficial use shall not apply to any Collateral where 
possession of the Collateral by Lender is required by law to perfect 
Lender's security interest in such Collateral. If Lender at any time has 
possession of any Collateral, whether before or after an Event of Default, 
Lender shall be deemed to have exercised reasonable care in the custody and 
preservation of the Collateral if Lender takes such action for that purpose 
as Grantor shall request or as Lender, in Lender's sole discretion, shall 
deem appropriate under the circumstances, but failure to honor any request 
by Grantor shall not of itself be deemed to be a failure to exercise 
reasonable care. Lender shall not be required to take any steps necessary 
to preserve any rights in the Collateral against prior parties, nor to 
protect, preserve or maintain any security interest given to secure the 
Collateral.

4.   LENDER'S DUTY OF CARE. Lender shall have no duty of care with respect 
to the Collateral except that Lender shall exercise reasonable care with 
respect to the Collateral in Lender's custody. Lender shall be deemed to 
have exercised reasonable care if such property is accorded treatment 
substantially equal to that which Lender accords its own property or if 
Lender takes such action with respect to the Collateral as Grantor shall 
request or agree to in writing, provided that no failure to comply with 
any such request nor any omission to do any such act requested by Grantor 
shall be deemed a failure to exercise reasonable care. Lender's failure to 
take steps to preserve rights against any parties or property shall not be 
deemed to be failure to exercise reasonable care with respect to the 
Collateral in Lender's custody.

5.   WAIVERS. Grantor waives demand, protest, notice of protest, notice 
of default or dishonor, notice of payment and nonpayment, notice of any 
default, nonpayment at maturity, release, compromise, settlement, extension
or renewal of any or all commercial paper, 

<PAGE>

accounts, documents, instruments, chattel paper, and guaranties at any 
time held by Lender on which Grantor may in any way be liable.

6.   ASSIGNMENT AND PLEDGE OF ADDITIONAL RIGHTS. Grantor, in order to 
further secure the prompt and punctual payment and satisfaction of the 
Indebtedness in favor of Lender in principal, interest, costs, expenses, 
attorneys' fees and other fees and charges, hereby assigns, pledges and 
grants to Lender a security interest in the following additional rights 
(the "Rights"):

     (a)  Options and Agreements to Sell. Any and all of Grantor's present 
     and future options or agreements to sell the Collateral, or any part 
     or parts thereof, including without limitation, Grantor's rights to 
     exercise and/or enforce such options or agreements.

     (b)  Sale Proceeds. Any and all of Grantor's present and future rights,
     title and interest in and to any and all cash, cash equivalent, 
     property and other proceeds derived or to be derived from the sale, 
     transfer, assignment and/or other distribution of the Collateral, 
     whether in cash, farm products, or otherwise, and whether from or 
     through any federal or state government agency or program or otherwise,
     including without limitation all rights to payments by or through the 
     Commodity Credit Corporation or the ASCS; all rights to payments for 
     participation in the Agricultural Conservation Program, the Cropland 
     Adjustment Program, the Cropland Conversion Program, the National Wool 
     Act of 1954, the Wheat, Feed Grain and Cotton Programs of the Agricul-
     tural Adjustment Act of 1938, and any other such programs of the 
     United States Department of Agriculture; and all payments in kind, 
     including without limitation PIK certificates and commodities redeemed
     or acquired by PIK certificates, warehouse receipts, chemicals and 
     fertilizers, documents, letters of entitlement, and deficiency, conser-
     vation reserve, and diversion and storage payments, together with, 
     Grantor's rights to receive such proceeds and Grantor's rights to en-
     force collection and payment thereof.

     (c)  Insurance Proceeds. Any and all of Grantor's present and future 
     rights, title and interest in and to any unearned insurance premiums 
     and proceeds of insurance affecting all or any part of the Collateral,
     including the right to receive such unearned insurance premiums and 
     insurance proceeds directly from the insurer and, where applicable, 
     to enforce any rights that Grantor may have to collect such amounts.

     (d)  Condemnation Proceeds. Any and all of Grantor's present and 
     future rights, title and interest in and to the proceeds of any award 
     or claim for direct or consequential damages relating to any condemna-
     tion, expropriation, or any part of the Collateral by any governmental
     authority, including the right to receive such condemnation proceeds 
     directly from such a governmental authority and, where applicable, to 
     enforce frights that Grantor may have to collect such condemnation
     proceeds.

     (e)  Damages. Any and all of Grantor's rights, title and interest and 
     other claims or demands that Grantor now has or may hereafter acquire 
     against anyone with respect to any damage to all or any part of the 
     Collateral.

7.   EXPENDITURES BY LENDER. If not discharged or paid when due, Lender 
may (but shall not be obligated to) discharge or pay any amounts required 
to be discharged or paid by Grantor under this Agreement, including without
limitation all taxes, liens, security interests, encumbrances, and other 
claims, at any time levied or placed on the Collateral. Lender also may 
(but shall not be obligated to) pay all costs for insuring, maintaining and
preserving the Collateral. All such expenditures incurred or paid by Lender
for such purposes will then bear interest at the rate charged under the 
Note from the date incurred or paid by Lender to the date of repayment by 
Grantor. All such expenses shall become a part of the Indebtedness and, at 
Lender's option, will (a) be payable on demand, (b) be added to the balance
of the Note and be apportioned among and be payable with any installment 
payments to become due during either (i) the term of any applicable insur-
ance policy or (ii) the remaining term of the Note, or (c) be treated as a 
balloon payment which will be due and payable at the Note's maturity. This 
Agreement also will secure payment of these amounts.  Such right shall be 
in addition to all other nights and remedies to which Lender may be entitled
upon the occurrence of an Event of Default.

8.   EVENTS OF DEFAULT. Each of the following shall constitute an Event of 
Default under this Agreement:

     (a)  Default on Indebtedness. An event of default as defined in the 
     Note.

     (b)  Other Defaults. Failure of Grantor to comply with or to perform 
     any other term, obligation, covenant or condition contained in this 
     Agreement or in any of the Related Documents or in any other agreement
     between Lender and Grantor, or the occurrence of any default or event 
     of default under any of the Related Documents.

     (c)  False Statements. Any warranty, representation or statement made 
     or furnished to Lender by or on behalf of Grantor under this Agreement
     is false or misleading in any material respect, either now or at the 
     time made or furnished.

     (d)  Defective Collateralization. This Agreement or any of the Related
     Documents ceases to be in full force and effect (including failure of 
     any collateral documents to create a valid and perfected security 
     interest or lien) at any time.

     (e)  Insolvency. The dissolution or termination of Grantor's existence
     as a going business, the insolvency of Grantor, the appointment of a 
     receiver for any part of Grantor's property, any assignment for the 
     benefit of creditors, or the commencement of any proceeding under any 
     bankruptcy or insolvency laws by or against Grantor.

<PAGE>

     (f)  Creditor Proceedings. Commencement of foreclosure, whether by 
     judicial proceeding, self-help, repossession or any other method, by 
     any creditor of Grantor or by any governmental agency against the 
     Collateral or any other collateral securing the Indebtedness.  This 
     includes a garnishment of any of Grantor's deposit accounts with 
     Lender.

     (g)  Forfeiture. The filing of formal charges under any federal or 
     state law against Grantor or the Collateral which forfeiture is a 
     potential penalty. However, this Event of Default shall not apply if 
     there is a good faith dispute by Grantor as to the validity or 
     reasonableness of the claim which is the basis of the proceeding and 
     if Grantor gives Lender written notice of the proceeding and deposits 
     with Lender monies or a surety bond for the proceeding in an amount 
     determined in good faith by Lender as being an adequate reserve or 
     bond for the dispute.

     (h)  Events Affecting Guarantor. Any of the preceding events occurs 
     with respect to any Guarantor of any of the Indebtedness.

9.   RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under 
this Agreement, at any time thereafter, Lender shall have all the rights of
a secured Party under the Florida Uniform Commercial Code. In addition and 
without limitation, Lender may exercise any one or more of the following 
rights and remedies:

     (a)  Accelerate Indebtedness. Lender may declare the entire Indebted-
     ness, including any prepayment penalty which Grantor would be required
     to pay, immediately due and payable, without presentment, demand, 
     protest, or notice, all of which are expressly waived by Grantor.

     (b)  Processing of Collateral. Grantor hereby agrees that Lender or 
     its designate may do whatever Lender in its sole discretion deems to 
     be commercially reasonable to prepare any Collateral for disposition 
     and to dispose of any Collateral, including without limitation 
     operating any manufacturing or other processes relating to the 
     Collateral. Lender may transfer Collateral into its name or that of 
     a nominee and receive the dividends, royalties or income thereof. 
     Lender shall have no duty as to the collection or protection of the 
     Collateral or any income therefrom, nor as to the preservation of 
     rights against prior parties, nor as to the preservation of any right 
     pertaining thereto.

     (c)  Actions regarding Collateral.  Lender may dispose of the Col-
     lateral in its then-existing condition or, at its election, may take 
     such measures as it deems necessary or advisable to refurbish, repair,
     improve, process, finish, operate, demonstrate, and prepare for sale 
     the Collateral and may store, ship, reclaim, recover, protect, adver-
     tise for sale or lease, and insure the Collateral. If any Collateral 
     consists of documents, Lender may proceed either as to the documents 
     or as to the goods represented thereby. Lender may pay, purchase, 
     contest, or compromise any encumbrance, charge, or lien that, in the 
     opinion of Lender, appears to be prior or superior to its lien and pay
     all expenses incurred in connection therewith.

     (d)  Assemble Collateral. Lender may require Grantor to deliver to 
     Lender all or any portion of the Collateral and any and all certifi-
     cates of title and other documents relating to the Collateral. Lender 
     may require Grantor to assemble the Collateral and make it available 
     to Lender at a place to be designated by Lender.  Lender also shall 
     have full power to enter upon the property of Grantor to take posses-
     sion of and remove the Collateral and Lender may remain on such 
     premises and use the premises for the purpose of collecting, preparing,
     and disposing of the Collateral, without any liability for rent or 
     occupancy charges. If the Collateral contains other goods not covered 
     by this Agreement at the time of repossession, Grantor agrees Lender 
     may take such other goods, provided that Lender makes reasonable 
     efforts to return them to Grantor after repossession.

     (e)  Sell the Collateral. Lender shall have full power to sell, lease,
     transfer, or otherwise deal with the Collateral or proceeds thereof in 
     its own name or that of Grantor. Lender may sell the Collateral at 
     public auction or private sale. Unless the Collateral threatens to 
     decline speedily in value or is of a type customarily sold on a 
     recognized market, Lender will give Grantor reasonable notice of the 
     time after which any private sale or any other intended disposition 
     of the Collateral is to be made. The requirements of reasonable notice
     shall be met if such notice is given at least ten (10) days before 
     the time of the sale or disposition. Lender may adjourn any public or 
     private sale from time to time to a reasonably specified time and 
     place by announcement at the time and place of sale previously fixed,
     without further notice by publication or otherwise of the time and 
     place of such adjourned sale, and such sale may, without further 
     notice, be made at the time and place to which it was so adjourned. 
     All expenses relating to the disposition of the Collateral, including 
     without limitation the expenses of retaking, holding, insuring, pre-
     paring for sale and selling the Collateral, shall become a part of 
     the Indebtedness secured by this Agreement and shall be payable on 
     demand, with interest at the Note default rate from date of expendi-
     ture until repaid.

     (f)  Appoint Receiver. To the extent permitted by applicable law, 
     Lender shall have the following rights and remedies regarding the 
     appointment of a receiver: (i) Lender may have a receiver appointed 
     as a matter of right, (ii) the receiver may be an employee of Lender 
     and may serve without bond, (iii) all fees of the receiver and his or 
     her attorney shall become a part of the Indebtedness secured by this 
     Agreement and shall be payable on demand, with interest at the Note 
     rate from date of expenditure until repaid, and (iv) Lender, any 
     affiliate of Lender or any other person or entity, shall upon any 
     public sale(s) and, to the extent permitted by law, upon any private 
     sale(s) have the right to purchase the whole or any part of the Col-
     lateral so sold, free of any right or equity of redemption of Grantor.

<PAGE>

     (g)  Disposition of Collateral. Without demand of performance or other
     demand, advertisement or notice of any kind (except the notice(s) 
     specified herein regarding the time and place of public sale or dis-
     position or time after which a private sale or disposition is to occur)
     to Grantor (which all and each of demands, advertisements and/or 
     notices are hereby expressly waived), Lender may forthwith collect, 
     receive, appropriate and realize upon the Collateral, in full or in 
     any part thereof, may abandon, not claim or not take possession of any
     Collateral, and/or may forthwith sell, lease, assign, give an option 
     or options to purchase or sell or otherwise dispose of and deliver 
     the Collateral (or contract to do so), or any part thereof, in one or 
     more parcels at public or private sale(s) at Lender's offices or 
     elsewhere at such price(s) as Lender may determine, for cash or on 
     credit or for future delivery without assumption of any credit risk.

     (h)  Collect Revenues, Apply Accounts. Lender, either itself or 
     through a receiver, may collect the payments, rents, income, and 
     revenues from the Collateral.   Lender may at any time in its dis-
     cretion transfer any Collateral into its own name or that of its 
     nominee and receive the payments, rents, income, and revenues there-
     from and hold the same as security for the Indebtedness or apply it 
     to payment of the Indebtedness in such order of preference as Lender 
     may determine.   Insofar as the Collateral consists of accounts, 
     general intangibles, insurance policies, instruments, chattel paper, 
     choses in action, or similar property, Lender may demand, collect, 
     receipt for, settle, compromise, adjust, sue for, foreclose, or 
     realize on the Collateral for cash, credit or otherwise as Lender may 
     determine, whether or not Indebtedness or Collateral is then due. For 
     these purposes, Lender may, on behalf of and in the name of Grantor, 
     receive, open and dispose of mail addressed to Grantor; change any 
     address to which mail and payments are to be sent; endorse and/or 
     sign the name of Grantor on notes, checks, drafts, money orders, 
     documents of title, instruments and items pertaining to payment, 
     shipment, or storage of any Collateral; grant credit extensions of 
     time or payment or performance or any other indulgences to anyone 
     with respect to any account; accept the return of the goods represented
     by any account; or do anything else which Grantor would be legally 
     permitted to do.  To facilitate collection, Lender may notify account 
     debtors and obligors on any Collateral to make payments directly to 
     Lender.

     Lender shall apply the net proceeds of any such collection, recovery, 
     receipt, appropriation, realization or sale, after deducting all 
     reasonable costs and expenses of every kind incurred in connection 
     therewith or incidental to the care or safekeeping of any or all of 
     the Collateral or in any way relating to the rights of Lender here-
     under, including attorneys' fees and legal expenses, to the payment 
     in whole or in part of the Indebtedness, in such order as Lender may 
     elect, and only after applying such net proceeds and after the payment
     by Lender of any other amount required by any provision of law, need 
     Lender account for the surplus, if any to Grantor.

     (i)  Obtain Deficiency. Grantor shall remain liable for any deficiency
     if the proceeds of any sale or disposition of the Collateral are 
     insufficient to pay all amounts to which Lender is entitled even if 
     the transaction described in this subsection is a sale of accounts or 
     chattel paper. If Lender chooses to sell any or all of the Collateral,
     Lender may obtain a judgment against Grantor for any deficiency 
     remaining on the Indebtedness due to Lender after application of all 
     amounts received from the exercise of the rights provided in this 
     Agreement.

     (j)  Waiver. To the extent permitted by applicable law, Grantor waives
     all claims, damages and demands against Lender arising out of the 
     repossession, retention, sale or disposition of the Collateral.

     (k)  License. Lender is hereby granted a license or other right to use,
     without charge, Grantor's patents, copyrights, trade secrets, technical
     processes, rights of use of any name, trade names, trademarks, labels,
     and advertising matter, or any property of a similar nature, as it 
     pertains to the Collateral, in completing production of, advertising 
     for sale, and selling any Collateral, and Grantor's rights under all 
     licenses and all franchise agreements shall inure to Lender's benefit.

     (l)  Other Rights and Remedies. Lender shall have all the rights and 
     remedies of a secured creditor under the provisions of the Uniform 
     Commercial Code, as may be amended from time to time. In addition, 
     Lender shall have and may exercise any or all other rights and 
     remedies it may have available at law, in equity, or otherwise.

     (m)  Cumulative Remedies. All of Lender's rights and remedies, whether
     evidenced by this Agreement or the Related Documents or by any other 
     writing, shall be cumulative and may be exercised singularly or con-
     currently. Election by Lender to pursue any right or remedy concurrent-
     ly or in any sequence shall not exclude pursuit of any other right or 
     remedy concurrently or in any sequence, and an election to make ex-
     penditures or to take action to perform an obligation of Grantor under
     this Agreement, after Grantor's failure to perform, shall not affect 
     Lender's right to declare a default and to exercise its remedies.

10.  MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a 
part of this Agreement:

     (a)  Amendments. This Agreement, together with any Related Documents, 
     constitutes the entire understanding and agreement of the parties as 
     to the matters set forth in this Agreement and supersedes all prior 
     understandings and correspondence, oral or written, with respect to 
     the subject matter hereof. No alteration of or amendment to this 
     Agreement shall be effective unless given in writing and signed by 
     the party or parties sought to be charged or bound by the alteration
     or amendment.

     (b)  Applicable Law. This Agreement shall be governed by and construed
     in accordance with the laws of the State of Florida.

<PAGE>

     (c)  Attorneys' Fees; Expenses. In any action in connection with the 
     Indebtedness, this Agreement or the enforcement of this Agreement, 
     the non-prevailing party shall pay the costs and expenses of the pre-
     vailing party.  Lender may pay someone else to enforce this Agreement 
     and Grantor shall pay the costs and expenses incurred in connection 
     therewith.  Lender need not commence a lawsuit in order to be eligible
     to recover costs and expenses (for example, costs and expenses for 
     bankruptcy proceedings, including, without limitation, efforts to 
     modify or vacate any automatic stay or injunction would be recoverable
     as would costs and expenses incurred in any appeals or any post-
     judgment collection services).  As used herein, costs and expenses 
     include, without limitation,  reasonable attorneys' fees and legal 
     expenses.  

     (d)  Caption Headings. Caption headings in this Agreement are for 
     convenience purposes only and are not to be used to interpret or 
     define the provisions of this Agreement.

     (e)  Extensions and Compromises. With respect to any Collateral or 
     the Indebtedness, Grantor assents to all extensions or postponements 
     to the time of payment thereof or any other indulgence in connection 
     therewith, to each substitution, exchange or release of Collateral, 
     to the release of any party primarily or secondarily liable, to the 
     acceptance of partial payment thereon or to the settlement or com-
     promise thereof, all in such manner and such time or times as Lender 
     may deem advisable. No forbearance in exercising any right or remedy 
     on any one or more occasions shall operate as a waiver thereof on any 
     future occasion; and no single or partial exercise of any right or 
     remedy shall preclude any other exercise thereof or the exercise of 
     any other right or remedy.

     (f)  Notices. All notices required to be given under this Agreement 
     shall be given in writing and shall be effective when actually

     specifying that the purpose of the notice is to change the party's

     (g)  Power of Attorney. Grantor hereby appoints Lender as its true and
     lawful attorney-in-fact, irrevocably, with full power of substitutions,
     do the following:  (i) to demand, collect, receive, receipt for, sue 
     and recover all sums of money or other property which may now or 
     hereafter become due, owing or payable from the Collateral; (ii) to 
     execute, sign and endorse any and all claims, instruments, receipts, 
     checks, drafts or warrants issued in payment for the Collateral; (iii) 
     to settle or compromise any and all claims arising under the Collateral
     and, in the place and stead of Grantor, to execute and deliver its 
     release and settlement for the claim; and (iv) to file any claim or 
     claims or to take any action or institute or take part in any pro-
     ceedings, either in its own name or in the name of Grantor, or other-
     wise, which in the discretion of Lender may seem to be necessary or 
     advisable. This power is given as security for the Indebtedness, and 
     the authority hereby conferred is and shall be irrevocable and shall 
     remain in full force and effect until renounced by Lender.

     (h)  Severability. If a court of competent jurisdiction finds any pro-
     vision of this Agreement to be invalid or unenforceable as to any 
     person or circumstance, such finding shall not render that provision 
     invalid or unenforceable as to any other persons or circumstances. If 
     feasible, any such offending provision shall be deemed to be modified 
     to be within the limits of enforceability or validity; however, if the
     offending provision cannot be so modified, it shall be stricken and 
     all other provisions of this Agreement in all other respects shall 
     remain valid and enforceable.

     (i)  Successor Interests. Subject to the limitations set forth above 
     on transfer of the Collateral, this Agreement shall be binding upon 
     and inure to the benefit of the parties, their successors and assigns.

<PAGE>

     (j)  Time. Time is of the essence of all requirements of Grantor herein.

     (k)  Waiver. Lender shall not be deemed to have waived any rights 
     under this Agreement unless such waiver is given in writing and signed
     by Lender. No delay or omission on the part of Lender in exercising 
     any right shall operate as a waiver of such right or any other right. 
     A waiver by Lender of a provision of this Agreement shall not 
     prejudice or constitute a waiver of Lender's right otherwise to demand 
     strict compliance with that provision or any other provision of this
     Agreement. No prior waiver by Lender, nor any course of dealing 
     between Lender and Grantor, shall constitute a waiver of any of 
     Lender's rights or of any of Grantor's obligations as to any future 
     transactions, circumstances or events.  Whenever the consent of Lender
     is required under this Agreement, the granting of such consent by 
     Lender in any instance shall not constitute continuing consent to 
     subsequent instances where such consent is required and in all cases 
     such consent may be granted or withheld in the sole discretion of 
     Lender.

11.  AUDITS. Lender reserves its right to conduct unannounced inventory 
audits, at its sole discretion, with the assistance of its Asset Based 
Lending Department. In addition, Lender shall make asset-based lending 
audits upon reasonable notice to Grantor and at the Grantor's expense.

12.  RELATED DOCUMENTS.  The obligations of Grantor under this Agreement 
are in addition to the obligations of Grantor under the Related Documents.

13.  WAIVER OF JURY TRIAL.  EACH GRANTOR AND THE LENDER (BY ITS ACCEPTANCE 
HEREOF) HEREBY KNOWINGLY, VOLUNTARILY, IRREVOCABLY AND UNCONDITIONALLY 
WAIVES TRIAL BY JURY IN ANY SUIT OR PROCEEDING ARISING OUT OF OR RELATED 
TO THIS AGREEMENT OR THE RELATED DOCUMENTS OR ANY COURSE OF CONDUCT, COURSE 
OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PERSON.
THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE LENDER TO MAKE THE LOAN 
EVIDENCED BY THE NOTE.


GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS COMMERCIAL

                            MASTER AGREEMENT

                      dated as of December 22, 1997



Techdyne, Inc.                                           Barnett Bank, N.A.
 ...........................(Party "A")  .........................(Party"B")

have entered and/or anticipate entering into one or more transactions (each
a "Transaction") that are or will be governed by this Master Agreement, 
which includes the schedule (the "Schedule"), and the documents and other 
confirming evidence (each a "Confirmation") exchanged between the parties 
confirming those Transactions.

Accordingly, the parties agree as follows: --

1.   Interpretation

(a)  Definitions. The terms defined in Section 12 and in the Schedule 
will have the meanings therein specified for the purpose of this Master 
Agreement.

(b)  Inconsistency. In the event of any inconsistency between the pro-
visions of the Schedule and the other provisions of this Master Agreement,
the Schedule will prevail. In the event of any inconsistency between the 
provisions of any Confirmation and this Master Agreement (including the 
Schedule), such Confirmation will prevail for the purpose of the relevant 
Transaction.

(c)  Single Agreement. All Transactions are entered into in reliance on 
the fact that this Master Agreement and all Confirmations form a single 
agreement between the parties (collectively referred to as this "Agree-
ment"), and the parties would not otherwise enter into any Transactions.


2.   Obligations

(a)  General Conditions.

     (i)   Each party will make each payment or delivery specified in 
     each Confirmation to be made by it, subject to the other provisions 
     of this agreement

     (ii)  Payments under this Agreement will be made on the due date 
     for value on that date in the place of the account specified in the 
     relevant Confirmation or otherwise pursuant to this Agreement, in 
     freely transferable funds and in the manner customary for payments 
     in the required currency. Where settlement is by delivery (that is, 
     other than by payment), such delivery will be made for receipt on the 
     due date in the manner customary for the relevant obligation unless 
     otherwise specified in the relevant Confirmation or elsewhere in this 
     Agreement.

<PAGE>

     (iii) Each obligation of each party under Section 2(a)(i) is subject 
     to (l) the condition precedent that no Event of Default or Potential 
     Event of Default with respect to the other party has occurred and is 
     continuing, (2) the condition precedent that no Early Termination Date
     in respect of the relevant Transaction has occurred or been effective-
     ly designated and (3) each other applicable condition precedent 
     specified in this Agreement.

(b)  Change of Account. Either party may change its account for receiving 
a payment or delivery by giving notice to the other party at least five 
Local Business Days prior to the scheduled date for the payment or delivery
to which such change applies unless such other party gives timely notice 
of a reasonable objection to such change.

(c)  Netting.  If on any date amounts would otherwise be payable: --

     (i)   in the same currency; and

     (ii)  in respect of the same Transaction,

by each party to the other, then, on such date, each party's obligation 
to make payment of any such amount will be automatically satisfied and 
discharged and, if the aggregate amount that would otherwise have been 
payable by one party exceeds the aggregate amount that would otherwise 
have been payable by the other party, replaced by an obligation upon the 
party by whom the larger aggregate amount would have been payable to pay 
to the other party the excess of the larger aggregate amount over the 
smaller aggregate amount.

The parties may elect in respect of two or more Transactions that a net 
amount will be determined in respect of all amounts payable on the same 
date in the same currency in respect of such Transactions, regardless of 
whether such amounts are payable in respect of the same Transaction. The 
election may be made in the Schedule or a Confirmation by specifying that 
subparagraph (ii) above will not apply to the Transactions identified as 
being subject to the election, together with the starting date (in which 
case subparagraph (ii) above will not, or will cease to, apply to such 
Transactions from such date). This election may be made separately for 
different groups of Transactions and will apply separately to each pairing 
of branches or offices through which the parties make and receive payments 
or deliveries.

(d)  Default Interest; Other Amounts. Prior to the occurrence or effective 
designation of an Early Termination Date in respect of the relevant Trans-
action, a party that defaults in the performance of any payment obligation 
will, to the extent permitted by law and subject to Section 6(c), be 
required to pay interest (before as well as after judgment) on the overdue
amount to the other party on demand in the same currency as such overdue 
amount, for the period from (and including) the original due date for 
payment to (but excluding) the date of actual payment, at the Default 
Rate. Such interest will be calculated on the basis of daily compounding 
and the actual number of days elapsed. If, prior to the occurrence or
effective designation of an Early Termination Date in respect of the rele-
vant Transaction, a party defaults in the performance of any obligation 
required to be settled by delivery, it will compensate the other party on 
demand if and to the extent provided for in the relevant Confirmation or 
elsewhere in this Agreement.

3.   Representations

Each party represents to the other party (which representations will be 
deemed to be repeated by each party on each date on which a Transaction is 
entered into) that: --

(a)  Basic Representations.

     (i)    Status. It is duly organised and validly existing under the 
     laws of the jurisdiction of its organisation or incorporation and, if 
     relevant under such laws, in good standing;

<PAGE>

     (ii)   Powers. It has the power to execute this Agreement and any other 
     documentation relating to this Agreement to which it is a party, to 
     deliver this Agreement and any other documentation relating to this 
     Agreement that it is required by this Agreement to deliver and to 
     perform its obligations under this Agreement and any obligations it 
     has under any Credit Support Document to which it is a party and has 
     taken all necessary action to authorize such execution, delivery and 
     performance;

     (iii)  No Violation or Conflict. Such execution, delivery and per
     formance do not violate or conflict with any law applicable to it, any 
     provision of its constitutional documents, any order or judgment of 
     any court or other agency of government applicable to it or any of 
     its assets or any contractual restriction binding on or affecting it 
     or any of its assets;

     (iv)   Consents. All governmental and other consents that are required 
     to have been obtained by it with respect to this Agreement or any 
     Credit Support Document to which it is a party have been obtained and 
     are in full force and effect and all conditions of any such consents 
     have been complied with; and

     (v)    Obligations Binding. Its obligations under this Agreement and 
     any Credit Support Document to which it is a party constitute its 
     legal, valid and binding obligations, enforceable in accordance with 
     their respective terms (subject to applicable bankruptcy, reorganisa-
     tion, insolvency, moratorium or similar laws affecting creditors' 
     rights generally and subject, as to enforceability, to equitable 
     principles of general application (regardless of whether enforcement 
     is sought in a proceeding in equity or at law)).

(b)  Absence of Certain Events. No Event of Default or Potential Event 
of Default or, to its knowledge, Termination Event with respect to it 
has occurred and is continuing and no such event or circumstance would 
occur as a result of its entering into or performing its obligations under 
this Agreement or any Credit Support Document to which it is a party.

(c)  Absence of Litigation. There is not pending or, to its knowledge, 
threatened against it or any of its Affiliates any action, suit or pro-
ceeding at law or in equity or before any court, tribunal, governmental 
body, agency or official or any arbitrator that is likely to affect the 
legality, validity or enforceability against it of this Agreement or any 
Credit Support Document to which it is a party or its ability to perform 
its obligations under this Agreement or such Credit Support Document.

(d)  Accuracy of Specified Information. All applicable information that 
is furnished in writing by or on behalf of it to the other party and is 
identified for the purpose of this Section 3(d) in the Schedule is, as 
of the date of the information, true, accurate and complete in every 
material respect.

4.   Agreements

Each party agrees with the other that, so long as either party has or may 
have any obligation under this Agreement or under any Credit Support 
Document to which it is a party: --

(a)  Furnish Specified Information. It will deliver to the other party 
any forms, documents or certificates specified in the Schedule or any 
Confirmation by the date specified in the Schedule or such Confirmation 
or, if none is specified, as soon as reasonably practicable.

(b)  Maintain Authorizations. It will use all reasonable efforts to maintain 
in full force and effect all consents of any governmental or other authority
that are required to be obtained by it with respect to this Agreement or 
any Credit Support Document to which it is a party and will use all reason-
able efforts to obtain any that may become necessary in the future.

<PAGE>

(c)  Comply with Laws. It will comply in all material respects with all 
applicable laws and orders to which it may be subject if failure so to 
comply would materially impair its ability to perform its obligations under
this Agreement or any Credit Support Document to which it is a party.

5.   Events of Default and Termination Events

(a)  Events of Default. The occurrence at any time with respect to a party 
or, if applicable, any Credit Support Provider of such party or any 
Specified Entity of such party of any of the following events constitutes 
an event of default (an "Event of Default") with respect to such party: --

     (i)    Failure to Pay or Deliver. Failure by the party to make, when 
     due, any payment under this Agreement or delivery under Section 
     2(a)(i) or 2(d) required to be made by it if such failure is no 
     remedied on or before the third Local Business Day after notice of 
     such failure is given to the party;

     (ii)   Breach of Agreement. Failure by the party to comply with or 
     perform any agreement or obligation (other than an obligation to make 
     any payment under this Agreement or delivery under Section 2(a)(i) or 
     2(d) or to give notice of a Termination Event) to be complied with or 
     performed by the party in accordance with this Agreement if such 
     failure is not remedied on or before the thirtieth day after notice 
     of such failure is given to the party;

     (iii)  Credit Support Default.

          (1)  Failure by the party or any Credit Support Provider of such 
          party to comply with or perform any agreement or obligation to 
          be complied with or performed by it in accordance with any Credit
          Support Document if such failure is continuing after any applica-
          ble grace period has elapsed;

          (2)  the expiration or termination of such Credit Support Document 
          or the failing or ceasing of such Credit Support Document to be 
          in full force and effect for the purpose of this Agreement (in 
          either case other than in accordance with its terms) prior to 
          the satisfaction of all obligations of such party under each 
          Transaction to which such Credit Support Document relates without
          the written consent of the other party; or

          (3)  the party or such Credit Support Provider disaffirms, dis-
          claims, repudiates or rejects, in whole or in part, or challenges
          the validity of, such Credit Support Document;

     (iv)   Misrepresentation. A representation made or repeated or deemed 
     to have been made or repeated by the party or any Credit Support 
     Provider of such party in this Agreement or any Credit Support 
     Document proves to have been incorrect or misleading in any material 
     respect when made or repeated or deemed to have been made or repeated;

     (v)    Default under Specified Transaction. The party, any Credit 
     Support Provider of such party or any applicable Specified Entity 
     of such party (1) defaults under a Specified Transaction and, after 
     giving effect to any applicable notice requirement or grace period, 
     there occurs a liquidation of, an acceleration of obligations under, 
     or an early termination of, that Specified Transaction, (2) defaults, 
     after giving effect to any applicable notice requirement or grace 
     period, in making any payment or delivery due on the last payment, 
     delivery or exchange date of, or any payment on early termination of,
     a Specified Transaction (or such default continues for at least three 
     Local Business Days if there is no applicable notice requirement or 
     grace period) or (3) disaffirms, disclaims, repudiates or rejects, 
     in whole or in part, a Specified Transaction (or such action is taken 
     by any person or entity appointed or empowered to operate it or act 
     on its behalf);

<PAGE>

     (vi)    Cross Default. If "Cross Default" is specified in the 
     Schedule as applying to the party, the occurrence or existence of 
     (l) a default, event of default or other similar condition or event 
     (however described) in respect of such party, any Credit Support 
     Provider of such party or any applicable Specified Entity of such 
     party under one or more agreements or instruments relating to 
     Specified Indebtedness of any of them (individually or collectively)
     in an aggregate amount of not less than the applicable Threshold 
     Amount (as specified in the Schedule) which has resulted in such 
     Specified Indebtedness becoming, or becoming capable at such time 
     of being declared, due and payable under such agreements or instru-
     ments, before it would otherwise have been due and payable or (2) a 
     default by such party, such Credit Support Provider or such Specified
     Entity (individually or collectively) in making one or more payments 
     on the due date thereof in an aggregate amount of not less than the 
     applicable Threshold Amount under such agreements or instruments 
     (after giving effect to any applicable notice requirement or grace 
     period);

     (vii)  Bankruptcy. The party, any Credit Support Provider of such 
     party or any applicable Specified Entity of such party: --

          (1) is dissolved (other than pursuant to a consolidation, amalga-
          mation or merger); (2) becomes insolvent or is unable to pay its 
          debts or fails or admits in writing its inability generally to 
          pay its debts as they become due; (3) makes a general assignment,
          arrangement or composition with or for the benefit of its credi-
          tors; (4) institutes or has instituted against it a proceeding 
          seeking a judgment of insolvency or bankruptcy or any other relief 
          under any bankruptcy or insolvency law or other similar law 
          affecting creditors' rights, or a petition is presented for its 
          winding-up or liquidation, and, in the case of any such pro-
          ceeding or petition instituted or presented against it, such 
          proceeding or petition (A) results in a judgment of insolvency or 
          bankruptcy or the entry of an order for relief or the making of 
          an order for its winding-up or liquidation or (B) is not dis-
          missed, discharged, stayed or restrained in each case within 30

          tion (other than pursuant to a consolidation, amalgamation or 
          merger); (6) seeks or becomes subject to the appointment of an 
          administrator, provisional liquidator, conservator, receiver, 
          trustee, custodian or other similar official for it or for all

          tially all its assets and such secured party maintains possession,

          or is subject to any event with respect to it which, under the 
          applicable laws of any jurisdiction, has an analogous effect to 
          any of the events specified in clauses (1) to (7) (inclusive); 
          or (9) takes any action in furtherance of, or indicating its 
          consent to, approval of, or acquiescence in, any of the fore-
          going acts; or

     (viii) Merger Without Assumption. The party or any Credit Support 
     Provider of such party consolidates or amalgamates with, or merges 
     with or into, or transfers all or substantially all its assets to, 
     another entity and, at the time of such consolidation, amalgamation, 
     merger or transfer: --

          (1)  the resulting, surviving or transferee entity fails to assume 
          all the obligations of such party or such Credit Support Provider
          under this Agreement or any Credit Support Document to which it 
          or its predecessor was a party by operation of law or pursuant 
          to an agreement reasonably satisfactory to the other party to 
          this Agreement; or

          (2)  the benefits of any Credit Support Document fail to extend 
          (without the consent of the other party) to the performance
          by such resulting, surviving or transferee entity of its obli-
          gations under this Agreement.

<PAGE>

(b)  Termination Events. The occurrence at any time with respect to a 
party or, if applicable, any Credit Support Provider of such party or any 
Specified Entity of such party of any event specified below constitutes an 
Illegality if the event is specified in (i) below, and, if specified to be 
applicable, a Credit Event Upon Merger if the event is specified pursuant 
to (ii) below or an Additional Termination Event if the event is specified 
pursuant to (iii) below: --

     (i)    Illegality. Due to the adoption of, or any change in, any appli-
     cable law after the date on which a Transaction is entered into, or 
     due to the promulgation of, or any change in, the interpretation by 
     any court, tribunal or regulatory authority with competent jurisdic-
     tion of any applicable law after such date, it becomes unlawful 
     (other than as a result of a breach by the party of Section 4(b)) 
     for such party (which will be the Affected Party): --

          (1)  to perform any absolute or contingent obligation to make a 
          payment or delivery or to receive a payment or delivery in 
          respect of such Transaction or to comply with any other material 
          provision of this Agreement relating to such Transaction; or

          (2)  to perform, or for any Credit Support Provider of such 
          party to perform, any contingent or other obligation which the 
          party (or such Credit Support Provider) has under any Credit 
          Support Document relating to such Transaction;

     (ii)   Credit Event Upon Merger. If "Credit Event Upon Merger" is 
     specified in the Schedule as applying to the party, such party ("X"), 
     any Credit Support Provider of X or any applicable Specified Entity 
     or X consolidates or amalgamates with, or merges with or into, or 
     transfers all or substantially all its assets to, another entity and 
     such action does not constitute an event described in Section 
     5(a)(viii) but the creditworthiness of the resulting, surviving or 
     transferee entity is materially weaker than that of X, such Credit 
     Support Provider or such Specified Entity, as the case may be, immedi-
     ately prior to such action (and, in such event, X or its successor or 
     transferee, as appropriate, will be the Affected Party); or 

     (iii)  Additional Termination Event. If any "Additional Termination 
     Event" is specified in the Schedule or any Confirmation as applying, 
     the occurrence of such event (and, in such event, the Affected Party 
     or Affected Parties shall be as specified for such Additional Termina-
     tion Event in the Schedule or such Confirmation).

(c)  Event of Default and Illegality. If an event or circumstance which 
would otherwise constitute or give rise to an Event of Default also consti-
tutes an Illegality, it will be treated as an Illegality and will not 
constitute an Event of Default.

6.   Early Termination

(a)  Right to Terminate Following Event of Default. If at any time an Event 
of Default with respect to a party (the "Defaulting Party") has occurred 
and is then continuing, the other party (the "Non-defaulting Party") may, 
by not more than 20 days notice to the Defaulting Party specifying the 
relevant Event of Default, designate a day not earlier than the day such 
notice is effective as an Early Termination Date in respect of all out-
standing Transactions. If, however, "Automatic Early Termination" is 
specified in the Schedule as applying to a party, then an Early Termina-
tion Date in respect of all outstanding Transactions will occur immedi-
ately upon the occurrence with respect to such party of an Event of 
Default specified in Section 5(a)(vii)(1), (3), (5), (6) or, to the extent 
analogous thereto, (8), and as of the time immediately preceding the insti-
tution of the relevant proceeding or the presentation of the relevant peti-
tion upon the occurrence with respect to such party of an Event of Default 
specified in Section 5(a)(vii)(4) or, to the extent analogous thereto, (8).

(b)  Right to Terminate Following Termination Event.

<PAGE>

     (i)    Notice. If a Termination Event occurs, an Affected Party will, 
     promptly upon becoming aware of it, notify the other party, speci-
     fying the nature of that Termination Event and each Affected Trans-
     action and will also give such other information about that Termina-
     tion Event as the other party may reasonably require.

     (ii)   Two Affected Parties. If an Illegality under Section 5(b)(i)(1) 
     occurs and there are two Affected Parties, each party will use all 
     reasonable efforts to reach agreement within 30 days after notice 
     thereof is given under Section 6(b)(i) on action to avoid that 
     Termination Event.

     (iii)  Right to Terminate. If: --

          (1)  an agreement under Section 6(b)(ii) has not been effected 
          with respect to all Affected Transactions within 30 days after 
          an Affected Party gives notice under Section 6(b)(i); or

          (2)  an Illegality other than that referred to in Section 
          6(b)(ii), a Credit Event Upon Merger or an Additional Termina-
          tion Event occurs,

     either party in the case of an Illegality, any Affected Party in the 
     case of an Additional Termination Event if there is more than one 
     Affected Party, or the party which is not the Affected Party in the 
     case of a Credit Event Upon Merger or an Additional Termination Event 
     if there is only one Affected Party may, by not more than 20 days 
     notice to the other party and provided that the relevant Termination 
     Event is then continuing, designate a day not earlier than the day 
     such notice is effective as an Early Termination Date in respect of 
     all Affected Transactions.

(c)  Effect of Designation.

     (i)   If notice designating an Early Termination Date is given under 
     Section 6(a) or (b), the Early Termination Date will occur on the 
     date so designated, whether or not the relevant Event of Default or 
     Termination Event is then continuing.

     (ii)  Upon the occurrence or effective designation of an Early Termina-
     tion Date, no further payments or deliveries under Section 2(a)(i) or 
     2(d) in respect of the Terminated Transactions will be required to be 
     made, but without prejudice to the other provisions of this Agreement. 
     The amount, if any, payable in respect of an Early Termination Date 
     shall be determined pursuant to Section 6(e).

(d)  Calculations.

     (i)   Statement. On or as soon as reasonably practicable following 
     the occurrence of an Early Termination Date, each party will make 
     the calculations on its part, if any, contemplated by Section 6(e) 
     and will provide to the other party a statement (1) showing, in 
     reasonable detail, such calculations (including all relevant quota-
     tions and specifying any amount payable under Section 6(e)) and 
     (2) giving details of the relevant account to which any amount 
     payable to it is to be paid. In the absence of written confirmation 
     from the source of a quotation obtained in determining a Market 
     Quotation, the records of the party obtaining such quotation will 
     be conclusive evidence of the existence and accuracy of such quota-
     tion.

     (ii)  Payment Date. An amount calculated as being due in respect of any 
     Early Termination Date under Section 6(e) will be payable on the day 
     that notice of the amount payable is effective (in the case of an 
     Early Termination Date which is designated or occurs as a result of 
     an Event of Default) and on the day which is two Local Business Days 
     after the day on which notice of the amount payable is effective (in 
     the case of an Early Termination Date which is designated as a result 
     of a Termination Event). Such amount will be paid together with (to 
     the extent permitted under 

<PAGE>

     applicable law) interest thereon (before as well as after judgment), 
     from (and including) the relevant Early Termination Date to (but 
     excluding) the date such amount is paid, at the Applicable Rate. Such 
     interest will be calculated on the basis of daily compounding and the 
     actual number of days elapsed.

(e)  Payments on Early Termination. If an Early Termination Date occurs, 
the following provisions shall apply based on the parties' election in 
the Schedule of a payment measure, either 'Market Quotation" or "Loss", 
and a payment method, either the "First Method" or the "Second Method". 
If the parties fail to designate a payment measure or payment method in 
the Schedule, it will be deemed that "Market Quotation" or the "Second 
Method", as the case may be, shall apply. The amount, if any, payable in 
respect of an Early Termination Date and determined pursuant to this 
Section will be subject to any Set-off.

     (i)    Events of Default. If the Early Termination Date results from an 
     Event of Default: --

          (1)  First Method and Market Quotation. If the First Method and 
          Market Quotation apply, the Defaulting Party will pay to the 
          Non-defaulting Party the excess, if a positive number, of (A) 
          the sum of the Settlement Amount (determined by the Non-de-
          faulting Party) in respect of the Terminated Transactions and 
          the Unpaid Amounts owing to the Non-defaulting Party over (B) 
          the Unpaid Amounts owing to the Defaulting Party.

          (2)  First Method and Loss. If the First Method and Loss apply, the
          Defaulting Party will pay to the Non-defaulting Party, if a posi-
          tive number, the Non-defaulting Party's Loss in respect of this 
          Agreement.

          (3)  Second Method and Market Quotation.  If the Second Method and 
          Market Quotation apply, an amount will be payable equal to (A) 
          the sum of the settlement Amount (determined by the Non-defaulting
          Party) in respect of the Terminated Transactions and the Unpaid 
          Amounts owing to the Non-defaulting Party less (B) the Unpaid 
          Amounts owing to the Defaulting Party If that amount is a positive
          number, the Defaulting Party will pay it to the Non-defaulting 
          Party; if it is a negative number, the Non-defaulting Party will 
          pay the absolute value of that amount to the Defaulting Party.

          (4)  Second Method and Loss.  If the Second Method and Loss 
          apply, an amount will be payable equal to the Non-defaulting 
          Party's Loss in respect of this Agreement. If that amount is a 
          positive number, the Defaulting Party will pay it to the Non-
          defaulting Party; if it is a negative number, the Non-defaulting
          Party will pay the absolute value of that amount to the De-
          faulting Party.

     (ii)   Termination Events. If the Early Termination Date results from 
     a Termination Event: --

          (1)  One Affected Party. If there is one Affected Party, the 
     amount payable will be determined in accordance with Section 
     6(e)(i)(3), if Market Quotation applies, or Section 6(e)(i)(4), if 
     Loss applies, except that, in either case, references to the 
     Defaulting Party and to the Non-defaulting Party will be deemed to 
     be references to the Affected Party and the party which is not the 
     Affected Party, respectively, and, if Loss applies and fewer than 
     all the Transactions are being terminated, Loss shall be calculated 
     in respect of all Terminated Transactions.

          (2)  Two Affected Parties. If there are two Affected Parties: --

               (A)  if Market Quotation applies, each party will determine a
               Settlement Amount in respect of the Terminated Transactions, 
               and an amount will be payable equal to (I) the sum of 
               (a) one-half of the difference between the Settlement Amount 
               of 

<PAGE>

               the party with the higher Settlement Amount ("X") and the 
               Settlement Amount of the party with the lower Settlement 
               Amount ("Y") and (b) the Unpaid Amounts owing to X less 
               (II) the Unpaid Amounts owing to Y; and

               (B)  if Loss applies, each party will determine its Loss in 
               respect of this Agreement (or, if fewer than all the Trans-
               actions are being terminated, in respect of all Terminated 
               Transactions) and an amount will be payable equal to 
               one-half of the difference between the Loss of the party 
               with the higher Loss ("X') and the Loss of the party with 
               the lower Loss ("Y").

          If the amount payable is a positive number, Y will pay it to X; if 
          it is a negative number, X will pay the absolute value of that 
          amount to Y.

     (iii)  Adjustment for Bankruptcy. In circumstances where an Early 
     Termination Date occurs because "Automatic Early Termination" applies 
     in respect of a party, the amount determined under this Section 6(e) 
     will be subject to such adjustments as are appropriate and permitted 
     by law to reflect any payments or deliveries made by one party to the 
     other under this Agreement (and retained by such other party) during 
     the period from the relevant Early Termination Date to the date for 
     payment determined under Section 6(d)(ii).

     (iv)  Pre-Estimate. The parties agree that if Market Quotation applies 
     an amount recoverable under this Section 6(e) is a reasonable pre-esti-
     mate of loss and not a penalty. Such amount is payable for the loss of 
     bargain and the loss of protection against future risks and except as 
     otherwise provided in this Agreement neither party will be entitled 
     to recover any additional damages as a consequence of such losses.

7.   Transfer

Neither this Agreement nor any interest or obligation in or under this 
Agreement may be transferred (whether by way of security or otherwise) by 
either party without the prior written consent of the other party, except 
that: --

     (a)  a party may make such a transfer of this Agreement pursuant to a 
     consolidation or amalgamation with, or merger with or into, or 
     transfer of all or substantially all its assets to, another entity 
     (but without prejudice to any other right or remedy under this Agree-
     ment); and

     (b)  a party may make such a transfer of all or any part of its 
     interest in any amount payable to it from a Defaulting Party under 
     Section 6(e).

     Any purported transfer that is not in compliance with this Section 
will be void.

8.   Miscellaneous

     (a)  Entire Agreement. This Agreement constitutes the entire agreement 
     and understanding of the parties with respect to its subject matter 
     and supersedes all oral communication and prior writings with respect 
     thereto.

     (b)  Amendments. No amendment, modification or waiver in respect of 
     this Agreement will be effective unless in writing (including a 
     writing evidenced by a facsimile transmission) and executed by each 
     of the parties or confirmed by an exchange of telexes or electronic 
     messages on an electronic messaging system.

     (c)  Survival of Obligations. Without prejudice to Sections 2(a)(iii)
     and 6(c)(ii), the obligations of the parties under this Agreement will
     survive the termination of any Transaction.

<PAGE>

     (d)  Remedies Cumulative. Except as provided in this Agreement, the 
     rights, powers, remedies and privileges provided in this Agreement 
     are cumulative and not exclusive of any rights, powers, remedies and 
     privileges provided by law.

     (e)  Counterparts and Confirmations.

          (i)   This Agreement (and each amendment, modification and waiver 
          in respect of it) may be executed and delivered in counterparts 
          (including by facsimile transmission), each of which will be 
          deemed an original.

          (ii)  The parties intend that they are legally bound by the 
          terms of each Transaction from the moment they agree to those 
          terms (whether orally or otherwise). A Confirmation shall be 
          entered into as soon as practicable and may be executed and 
          delivered in counterparts (including by facsimile transmission) 
          or be created by an exchange of telexes or by an exchange of 
          electronic messages on an electronic messaging system, which 
          in each case will be sufficient for all purposes to evidence 
          a binding supplement to this Agreement. The parties will specify 
          therein or through another effective means that any such counter-
          part, telex or electronic message constitutes a Confirmation.

     (f)  No Waiver of Rights. A failure or delay in exercising any right, 
     power or privilege in respect of this Agreement will not be presumed 
     to operate as a waiver, and a single or partial exercise of any right, 
     power or privilege will not be presumed to preclude any subsequent or 
     further exercise, of that right, power or privilege or the exercise 
     of any other right, power or privilege.

     (g)  Headings. The headings used in this Agreement are for convenience
     of reference only and are not to affect the construction of or to be 
     taken into consideration in interpreting this Agreement.

9.   Expenses

A Defaulting Party will, on demand, indemnify and hold harmless the other 
party for and against all reasonable out-of-pocket expenses, including 
legal reasonable fees, incurred by such other party by reason of the en-
forcement and protection of its rights under this Agreement or any Credit 
Support Document to which the Defaulting Party is a party or by reason of 
the early termination of any Transaction, including, but not limited to, 
costs of collection.

10.  Notices

(a)  Effectiveness. Any notice or other communication in respect of this 
Agreement may be given in any manner set forth below (except that a notice

     sender's facsimile machine);

<PAGE>

     (iv)   if sent by certified or registered mail (airmail, if overseas) 
     or the equivalent (return receipt requested), on the date that mail 
     is delivered or its delivery is attempted; or

     (v)    if sent by electronic messaging system, on the date that elec-
     tronic message is received,

unless the date of that delivery (or attempted delivery) or that receipt, 
as applicable, is not a Local Business Day or that communication is 
delivered (or attempted) or received, as applicable, after the close of 
business on a Local Business Day, in which case that communication shall 
be deemed given and effective on the first following day that is a Local 
Business Day.

(b)  Change of Addresses. Either party may by notice to the other change 
the address, telex or facsimile number or electronic messaging system 
details at which notices or other communications are to be given to it.

11.  Governing Law and Jurisdiction

(a)  Governing Law. This Agreement will be governed by and construed in 
accordance with the law specified in the Schedule.

(b)  Jurisdiction. With respect to any suit, action or proceedings relating
to this Agreement ("Proceedings"), each party irrevocably: --

     (i)   submits to the jurisdiction of the English courts, if this Agree-
     ment is expressed to be governed by English law, or to the non-exclu-
     sive jurisdiction of the courts of the State of New York and the 
     United States District Court located in the Borough of Manhattan in 
     New York City, if this Agreement is expressed to be governed by the 
     laws of the State of New York; and

     (ii)  waives any objection which it may have at any time to the laying
     of venue of any Proceedings brought in any such court, waives any 
     claim that such Proceedings have been brought in an inconvenient forum
     and further waives the right to object, with respect to such Pro-
     ceedings, that such court does not have any jurisdiction over such 
     party.

Nothing in this Agreement precludes either party from bringing Proceedings
in any other jurisdiction (outside, if this Agreement is expressed to be 
governed by English law, the Contracting States, as defined in Section 1(3)
of the Civil Jurisdiction and Judgments Act 1982 or any modification, 
extension or re-enactment thereof for the time being in force) nor will 
the bringing of Proceedings in any one or more jurisdictions preclude the 
bringing of Proceedings in any other jurisdiction.

(c)  Waiver of Immunities. Each party irrevocably waives, to the fullest 
extent permitted by applicable law, with respect to itself and its revenues
and assets (irrespective of their use or intended use), all immunity on the
grounds of sovereignty or other similar grounds from (i) suit, (ii) juris-
diction of any court, (iii) relief by way of injunction, order for specific
performance or for recovery of property, (iv) attachment of its assets 
(whether before or after judgment) and (v) execution or enforcement of 
any judgment to which it or its revenues or assets might otherwise be 
entitled in any Proceedings in the courts of any jurisdiction and irre-
vocably agrees, to the extent permitted by applicable law, that it will 
not claim any such immunity in any Proceedings.

and (d) in relation to Section 5(a)(v)(2), in the relevant locations for 
performance with respect to such Specified Transaction.
 
"Loss" means, with respect to this Agreement or one or more Terminated 
Transactions, as the case may be, and a party, an amount that party 
reasonably determines in good faith to be its total losses and costs (or 
gain, in which case expressed as a negative number) in connection with 
this Agreement or that Terminated Transaction or group of Terminated 
Transactions, as the case may be, including any loss of bargain, cost 
of funding or, at the election of such party but without duplication, 
loss or cost incurred as a result of its terminating, liquidating, 
obtaining or reestablishing any hedge or related trading position (or any 
gain resulting from any of them). Loss includes losses and costs (or gains)
in respect of any payment or delivery required to have been made (assuming 
satisfaction of each applicable condition precedent) on or before the rele-
vant Early Termination Date and not made, except, so as to avoid duplica-
tion, if Section 6(e)(i)(1) or (3) or 6(e)(ii)(2)(A) applies. Loss does 
not include a party's legal fees and out-of-pocket expenses referred to 
under Section 9. A party will determine its Loss as of the relevant Early 
Termination Date, or, if that is not reasonably practicable, as of the 
earliest date thereafter as is reasonably practicable. A party may (but 
need not) determine its Loss by reference to quotations of relevant rates 
or prices from one or more leading dealers in the relevant markets.

"Market Quotation" means, with respect to one or more Terminated Transac-
tions and a party making the determination, an amount determined on the 
basis of quotations from Reference Market-makers. Each quotation will be 
for an amount, if any, that would be paid to such party (expressed as a 
negative number) or by such party (expressed as a positive number) in 
consideration of an agreement between such party (taking into account any 
existing Credit Support Document with respect to the obligations of such 
party) and the quoting Reference Market-maker to enter into a transaction 
(the "Replacement Transaction") that would have the effect of preserving 
for such party the economic equivalent of any payment or delivery (whether 
the underlying obligation was absolute or contingent and assuming the satis-
faction of each applicable condition precedent) by the parties under 
Section 2(a)(i) in respect of such Terminated Transaction or group of 
Terminated Transactions that would, but for the occurrence of the relevant 
Early Termination Date, have been required after that date. For this 
purpose, Unpaid Amounts in respect of the Terminated Transaction or group 
of Terminated Transactions are to be excluded but, without limitation, any 
payment or delivery that would, but for the relevant Early Termination 
Date, have been required (assuming satisfaction of each applicable condi-
tion precedent) after that Early Termination Date is to be included. The 
Replacement Transaction would be subject to such documentation as such 
party and the Reference Market-maker may, in good faith, agree. The party 
making the determination (or its agent) will request each Reference Market-
maker to provide its quotation to the extent reasonably practicable as of 
the same day and time (without regard to different time zones) on or as 
soon as reasonably practicable after the relevant Early Termination Date. 
The day and time as of which those quotations are to be obtained will be 
selected in good faith by the party obliged to make a determination under 
Section 6(e), and, if each party is so obliged, after consultation with 
the other. If more than three quotations are provided, the Market Quota-
tion will be the arithmetic mean of the quotations, without regard to the 
quotations having the highest and lowest values. If exactly three such 
quotations are provided, the Market Quotation will be the quotation 
remaining after disregarding the highest and lowest quotations. For this 
purpose, if more than one quotation has the same highest value or lowest 
value, then one of such quotations shall be disregarded. If fewer than 
three quotations are provided, it will be deemed that the Market Quotation 
in respect of such Terminated Transaction or group of Terminated Trans-
actions cannot be determined.

                  and Barnett Bank, N.A. ("Party B")

1.    Termination Provisions
      ----------------------

(a)  "Specified Entity" for purposes of Section 5(a)(v) means each party's 
Affiliates.  If a party or any Credit Support Provider of a party is a 
partnership, then for purposes of Sections 5(a)(v), 5(a)(vi), 5(a)(vii) 
and 5(b)(ii), "Specified Entity" also means each general partner of that 
partnership.

(b)  "Specified Transaction" has its meaning as defined in Section 12, 
provided that "Default under Specified Transaction" excludes Force Majeure 
as defined below.

(c)  "Cross Default" applies to both parties, but excludes Force Majeure.
"Force Majeure" means nonpayment resulting solely from a wire transfer or 
operational problem or error (so long as sufficient funds are available), 
or from the general unavailability of the relevant currency due to exchange
controls or other similar governmental action, but only if payment is made 
within three Business Days after the problem has been corrected, the error 
has been discovered or the currency becomes available.

With respect to Party A, "Cross Default" is amended by inserting at the 
end of Section 5(a)(vi): "or (3) any default, event of default or other 
similar condition or event (however described) under any Financial Agree-
ment."

"Specified Indebtedness" means any obligation (whether present, future, 
contingent or otherwise, as principal or surety or otherwise) in respect 
of borrowed money or relating to the payment or delivery of funds, securi-
ties or other property (including, without limitation, collateral).

"Threshold Amount" means, with respect to Party B, an amount (including 
its equivalent in another currency) equal to the higher of $10,000,000 or 
3% of its stockholders' equity as reflected on its most recent financial 
statements or call reports, and with respect to Party A, any amount of 
Specified Indebtedness.

(d)  "Credit Event Upon Merger" applies to both parties.

(e)  "Automatic Early Termination" does not apply to either party.

(f)  Payments on Early Termination.  "Market Quotation" and the "Second 
Method" apply, subject to the following:

     (i)  "Market Quotation" for any Terminated Transaction that is, or is 
     subject to, any unexercised option shall be determined by taking 
     into account the economic equivalent of the option.

     (ii) The Non-defaulting Party may, upon the occurrence of an Early 
     Termination Date, offset payments due by it under this Agreement 
     (or under any Specified Transaction) against, and apply such pay-
     ments to the satisfaction of, any obligations owing by the 
     Defaulting Party (including any Office of the Defaulting Party) to 
     the Non-defaulting Party or any of the Non-defaulting Party's Affil-
     iates (including any Office of the Non-defaulting Party or its 
     Affiliates) whether matured or unmatured, and it is a condition
     precedent to the Non-defaulting Party's obligation to make any such
     payments that such obligations of the Defaulting Party have been paid
     in full or 

<PAGE>

     satisfied by offset as contemplated hereunder. For this purpose, the 
     Non-defaulting Party may convert any such payments or obligations 
     into the currency of the other at a rate of exchange (including premi-
     ums and costs of exchange) at which it could purchase the relevant 
     currency acting in good faith.

(g)  "Additional Termination Event" applies to Party A if Party A, any
Credit Support Provider of Party A or any Specified Entity of Party A is 
a natural person, and means the death of, or the appointment of a guardian 
for, that natural person (in which case Party A will be the Affected Party 
for that purpose).

for the person(s) executing the Confirmation for Party A for that Trans-
action.

(b)  "Closing Documents" means an opinion of counsel covering Party A's 
Basic Representations under Section 3(a)(i), or in lieu thereof, Party A's 
Authorizing Documents for this Agreement and the Transactions and a duly 
executed incumbency certificate for the person(s) executing this Agreement
