hereunder, at any time prior to the expiration of the term of this Agreement,
without "Cause" (as such term is defined in Section 5.1 above), or otherwise
without any cause, reason or justification, provided that the Company provides
to the Employee at least sixty (60) days' prior written notice (the "Termination
Notice") of such termination. In the event of any such termination by the

salary then in effect for the shorter of (x) the fifteen-month period following

payment of salaries as then in effect, and the Company shall have no further
liability or other obligation of any kind whatsoever to the Employee.

                  5.3 Death of the Employee. In the event that the Employee

legally entitled descendants, or the personal representative, executor,
administrator or other proper legal representative on behalf of such
descendants, shall be entitled to receive and be paid solely the Employee's
salary through the date of death, and the Company shall have no further
liability or other obligation of any kind whatsoever to the Employee.

                  5.4 Disability of the Employee. In the event that the Employee
becomes incapacitated during the Term by reason of sickness, accident or other
mental or physical disability such that he is substantially unable to
performance his duties and responsibilities hereunder for a period of 60
consecutive days, or for shorter or intermittent periods aggregating 90 days
during any 12-month period (a "Disability"), the Company thereafter shall have
the right, in its sole and absolute discretion, to terminate the Employee's
employment under this Agreement by sending written notice of such termination to
the Employee or its legal guardian or other proper legal representative and
thereupon his employment hereunder shall immediately cease and terminate. In the
event of any such termination, the Employee shall be entitled to receive and be
paid solely the Employee's salary then in effect through the effective date of
termination and the Company shall have no further liability or other obligation
of any kind whatsoever to the Employee.

                  5.5 Termination by the Employee. Provided that the Company

the Employee may terminate the Employee's employment with the Company hereunder
at any time and for any reason. Employee must provide to the Company written
notice of such termination not less than 30 days prior to the date such
termination is to be effective. Upon any termination pursuant to this Section

Business").

                  6.2 The Employee agrees that, during the Term of this
Agreement and for two years following the termination or expiration of his
employment for any reason whatsoever, he will not, without the prior written
consent of the Company, either directly or indirectly, on his own behalf or in

records, proprietary receipts and/or processing techniques, information
regarding vendors and products, training and operations memoranda and similar

                  9.2 The Employee acknowledges and agrees that all Confidential
Information, and all physical embodiments thereof, are confidential to and shall
be and remain the sole and exclusive property of the Company. Upon request by
the Company, and in any event upon termination of the Employee's employment with

receipt of any final salary or benefit payments hereunder, the Employee shall
deliver to the Company all property belonging to the Company or any of its

breach of this Section 9 by the Employee.

                  9.3 The Employee agrees that he will not, either during the

and all conceptions and ideas for inventions, improvements, and valuable
discoveries, whether patentable or not, that are conceived or made by the
Employee, solely or jointly with another, during the Term of this Agreement and

hire." The Employee hereby assigns and agrees to assign all his interests
therein to the Company or its nominee. Whenever requested to do so by the
Company, the Employee shall execute any and all applications, assignments or
other instruments that the Company shall deem necessary to apply for and obtain
Letters Patent of the United States or any foreign country or to otherwise
protect the Company's interest therein.

         11. REASONABLENESS OF RESTRICTIONS. In the event that any provision
relating to time period or geographic area of any restriction set forth in

to exceed the maximum time period or area of restriction that the court deems
reasonable and enforceable, the time period or area of restriction which the

restriction.

         12. ENFORCEABILITY. Any provision of Sections 6, 7, 8, 9 or 10 which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, but shall be enforced to the
maximum extent permitted by law, and any such prohibition or unenforceability in
any jurisdiction shall not invalidate or render unenforceable such provision in
any other jurisdiction.

         13. INJUNCTION. It is recognized and hereby acknowledged by the parties
hereto that a breach by the Employee of any of the covenants contained in
Sections 6, 7, 8, 9 or 10 of this Agreement will cause irreparable harm and
damage to the Company, the monetary amount of which may be virtually impossible
to ascertain. As a result, the Employee recognizes and hereby acknowledges that
the Company shall be entitled to an injunction from any court of competent
jurisdiction enjoining and restraining any violation of any or all of the
covenants contained in Sections 6, 7, 8, 9 or 10 of this Agreement by the
Employee or any of his affiliates, associates, partners or agents, either
directly or indirectly, and that such right to injunction shall be cumulative
and in addition to whatever other remedies the Company may possess.

         14. ASSIGNMENT. The Employee shall not delegate his employment
obligations pursuant to this Agreement to any other person.

         15. EMPLOYER'S AUTHORITY. The relationship between the parties hereto
is that of employer and employee. The Employee agrees to observe and comply with
the rules and regulations of the Company, as adopted by the Company from time to
time with respect to the performance of the duties of the Employee. The Employee
acknowledges that he has no authority to enter into any contracts or other
obligations that are binding upon the Company unless such contracts or
obligations are authorized by the Board of Directors of the Company. The Company

                                       6
<PAGE>   7

shall have the power to direct, control and supervise the duties to be performed
by the Employee, the manner of performing said duties, and the time of
performing said duties.

         16. GOVERNING LAW. This Agreement, the rights and obligations of the
parties hereto, and any claims or disputes relating thereto, shall be governed
by and construed in accordance with the laws of the State of Florida, excluding
the choice of law rules thereof. The Company and the Employee each hereby
irrevocably submit to the jurisdiction of the state or federal courts located in
Dade County, Florida in connection with any suit, action or other proceeding
arising out of or relating to this Agreement and hereby agree not to assert, by
way of motion, as a defense, or otherwise in any such suit, action or proceeding
that the suit, action or proceeding is brought in an inconvenient forum, that
the venue of the suit, action or proceeding is improper or that this Agreement
or the subject matter hereof may not be enforced by such courts.

         17. ENTIRE AGREEMENT. This Agreement constitutes the entire agreement
between the parties hereto with respect to the subject matter hereof and
supersedes all prior agreements, understandings and arrangements, both oral and
written, between the parties hereto with respect to such subject matter. This

all of which are inserted conditionally on their being valid in law, and, in the

invalid, this Agreement shall be construed as if such invalid word or words,

duly executed by the Company and the Employee. No delay or failure at any time
on the part of the Company in exercising any right, power or privilege under
this Agreement, or in enforcing any provision of this Agreement, shall impair
any such right, power or privilege, or be construed as a waiver of any default
or as any acquiescence therein, or shall affect the right of the Company
thereafter to enforce each and every provision of this Agreement in accordance
with its terms. The waiver by either party hereto of a breach or violation of
any term or provision of this Agreement shall neither operate nor be construed
as a waiver of any subsequent breach or violation.
