            7.    Bank, in its discretion, may transfer Borrower's Obligations
                  to its Commercial Finance Division.

      B.    Waiver of Covenant Default.

            Bank hereby waives Borrower's existing default under the Loan

            waiver of Borrower's compliance of this covenant shall apply only to
            the foregoing period.

            Bank's agreement to waive the above-described default (1) in no way

            compliance with the above-described covenant as of all other dates
            and (2) shall not limit or impair the Bank's right to demand strict
            performance of this covenant as of all other dates and (3) shall not
            limit or impair the Bank's right to demand strict performance of all
            other covenants as of any date.

necessary to reflect the changes described above.

Thousand Dollars ($15,000) (the "Loan Fee") plus all out-of-pocket expenses.

6. NO DEFENSES OF BORROWER. Borrower (and each guarantor and pledgor signing
below) agrees that, as of the date hereof, it has no defenses against the
obligations to pay any amounts under the Indebtedness.

7. CONTINUING VALIDITY. Borrower (and each guarantor and pledgor signing below)
understands and agrees that in modifying the existing Indebtedness, Lender is
relying upon Borrower's representations, warranties, and agreements, as set
forth in the Existing Loan Documents. Except as expressly modified pursuant to
this Loan Modification Agreement, the terms of the Existing Loan Documents
remain unchanged and in full force and effect. Lender's agreement to
modifications to the existing Indebtedness pursuant to this Loan Modification
Agreement in no way shall obligate Lender to make any future modifications to
the Indebtedness. Nothing in this Loan Modification Agreement shall constitute a
satisfaction of the Indebtedness. It is the intention of Lender and Borrower to
retain as liable parties all makers and endorsers of Existing Loan Documents,
unless the party is expressly released by Lender in writing. No maker, endorser,
or guarantor will be released by virtue of this Loan Modification Agreement. The
terms of this paragraph apply not only to this Loan Modification Agreement, but
also to all subsequent loan modification agreements.

8. CONDITIONS. The effectiveness of this Loan Modification Agreement is
conditioned upon Borrower's payment of the Loan Fee.

         employee,  officer, director,  partner, consultant or otherwise) in any
         person,  firm,  partnership,   association,   corporation  or  business
         organization,  entity or enterprise that competes with or is engaged in
         a  business  which is  substantially  similar  to the  business  of the
         Company  except that  ownership of not more than 5% of the  outstanding
         securities of any class of any  publicly-held  corporation shall not be
         deemed a violation of this sub-paragraph 3(b).

     (c) The Employee shall  promptly  disclose to the directors of the Company,
         in accordance with the Company's policies,  full information concerning
         any interests,  direct or indirect,  she holds (whether as a principal,
         stockholder,  lender, Employee,  director, officer, partner, consultant

         Employee  purchases or provides services or products to, the Company or
         any of its  subsidiaries,  provided that the Employee need not disclose
         any such interest  resulting  from ownership of not more than 5% of the
         outstanding securities of any class of any publicly-held corporation.

         judgment,  in the due  performance of her duties under this  Agreement)
         any confidential or secret  information with respect to the business or
         affairs of the Company, or any of its subsidiaries or affiliates.

participating in other business opportunities if and to the extent that (i) such
business  opportunities  are not  directly  competitive  with or  similar to the
business of the Company, and (ii) the Employee's activities with respect to such
opportunities  do not have a material  adverse effect on the  performance of the
Employee's duties hereunder.

court of competent  jurisdiction  to be too broad to permit  enforcement of such
restriction to its full extent,  then such restriction  shall be enforced to the
maximum  extent  permitted by law, and the Employee  hereby  consents and agrees
that such scope may be judicially modified accordingly in any proceeding brought
to enforce such restriction. All provisions of this Agreement are severable, and
the  unenforceability  or  invalidity of any single  provision  hereof shall not
affect any remaining  provision.  The Employee  acknowledges and agrees that the
Company's remedy at law for any breach of any of her obligations hereunder would
be inadequate,  and agrees and consents that temporary and permanent  injunctive
relief  may be  granted in any  proceeding  that may be  brought to enforce  any
provision of this Agreement  without the necessity of proof of actual damage and
without any bond or other  security being  required.  Such remedies shall not be
exclusive  and shall be in  addition to any other  remedy  which the Company may
have.

      10.   Miscellaneous.

     (a) The failure of a party to insist on any occasion upon strict  adherence
         to any Term of this Agreement shall not be considered to be a waiver or
         deprive  that  party of the  right  thereafter  to insist  upon  strict
         adherence to that Term or any other Term of this Agreement.  Any waiver
         must be in writing.

     (b) All notices and other  communications  under this Agreement shall be in
         writing and shall be delivered personally or mailed by registered mail,
         return receipt  requested,  and shall be deemed given when so delivered
         or mailed,  to a party at such  address  as a party  may,  from time to
         time, designate in writing to the other party.

     (c) This Agreement shall be assigned to and inure to the benefit of, and be
         binding  upon,  any  successor to  substantially  all of the assets and
         business  of  the  Company  as a  going  concern,  whether  by  merger,
         consolidation,  liquidation or sale of substantially  all of the assets
         of the Company or otherwise.

     (d) This Agreement  constitutes  the entire  Agreement  between the parties
         regarding the above matters, and each party acknowledges that there are
         no other  written or verbal  Agreements or  understandings  relating to
         such subject matter between the Employee and the Company or between the
         Employee  and any other  individuals  or entities  other than those set
         forth herein.  No amendment to this Agreement shall be effective unless
         it is in writing and signed by both the parties hereto.

     (e) This Agreement shall be construed according to the laws of the State of
         Florida  pertaining  to  Agreements  formed and to be performed  wholly
         within the State of Florida.  In the event action be brought to enforce
         any  provisions  of this  Agreement,  the  prevailing  party  shall  be
         entitled  to  reasonable  attorney's  fees as fixed by the  court.  The
         Employee  represents  and warrants that she has reviewed this Agreement
         in  detail  with  her  legal  and  other  advisors,  as  she  considers
         appropriate,  and that she fully understands the consequences to her of
         its  provisions.  The  Employee is relying on her own  judgment and the
         judgment  of her  advisors  with  respect  to  this  Agreement  and she
         understands  that the  Company  is  making  no  representations  to her
         concerning taxes or any other matters respecting this Agreement.

     (f) Any dispute  between the parties to this Agreement  shall be determined
         and settled by binding  arbitration  in  Clearwater,  Florida under the
         rules of the American  Arbitration  Association.  Judgment on any award
         rendered  by  the  arbitrators  may be  entered  in  any  court  having
         jurisdiction over the party adversely by such award.

     (g) This Agreement may be executed in any number of  counterparts,  each of
         which shall be deemed to be an original for all purposes hereof.

      IN WITNESS  WHEREOF,  the parties hereto have set their hands on this 30th
day of July, 2000.
