         10. TERMINATION.

                  a. Notwithstanding anything contained in this Agreement,
Employer by written notice to Employee shall at all times in its sole discretion
have the right to terminate this Agreement, and Employee's employment hereunder,
"for cause" effective upon delivery of notice to Employee. For purposes for this
Agreement, "for cause" shall mean: (i) any conviction of Employee of a felony;

Employer; (iii) a material act of fraud or dishonesty not involving Employer
which has a material adverse effect upon the Business or reputation of Employer;
(iv) continuing material violation by Employee of his obligations under this

violation within fifteen (15) days following such notice.

                  b. Employer by written notice to Employee shall have the right
to terminate this Agreement and Employee's employment upon the total and
permanent physical or mental disability ("Disability") of Employee, evidenced by
an inability to engage in his assigned duties for

                                       3
<PAGE>

a period of 180 or more days, either consecutively or in the aggregate during
any nine-month period, as determined by an impartial reputable physician agreed
upon by the Board and Employee (or his representative, as the case may be).

                  c. If Employee dies during the term of his employment
hereunder, this Agreement shall terminate automatically upon the date of
Employee's death.

         11. PAYMENTS UPON TERMINATION OR EXPIRATION.

                  a. In the event that this Agreement, and Employee's employment
hereunder, is terminated for cause pursuant to Section 10(a) hereof, then, in
such event, (i) Employer shall have no obligation whatsoever to make any
payment, including, without limitation, any payment of Salary, bonus, automobile
allowance or any insurance premium, to or on behalf of Employee for any period
subsequent to the date of such termination; and (ii) Employer may, subject to
the terms of such plans and applicable law remove Employee from coverage under
any medical, life, disability or other insurance plans or programs made
available to Employee by Employer.

                  b. In the event that this Agreement, and Employee's employment
hereunder, is terminated for death or Disability of Employee pursuant to Section
10(b) or 10(c) hereof, then, in any such event, Employer shall have no
obligation whatsoever to make any payment, including without limitation, any
payment of Salary, bonus, automobile allowance or any such insurance premium, to
or on behalf of Employee for any period subsequent to the date of such
termination or expiration. Notwithstanding the above, in the event this
Agreement is terminated for Disability of Employee pursuant to Section 10(b)
hereof, Employee shall have the right at Employer's expense through the
remaining term of this Agreement to continue such disability insurance as
Employer was providing as of the date of termination, and, at Employee's own
expense, to continue any group medical insurance then provided to Employee and
to such other benefits as he is then entitled under such insurance and any
disability plan or program of Employer.

                  c. In the event that this Agreement, and Employee's employment
hereunder, is terminated by Employer without cause during the terms set forth in
Section 2 hereof, or Employee shall terminate his employment with Employer as a
result of a material breach by Employer of the terms hereof, which breach is not
cured within fifteen (15) days following notice in writing from Employee to
Employer specifying the nature of such breach, then, in such event, in addition
to such amounts as have accrued prior to the date of termination and have not
previously been paid including any accrued vacation benefits, Employer shall pay
to Employee, payable at such time as such payments would otherwise be payable
hereunder, Employee's Salary, and any bonus the Board has otherwise approved
prior to termination, and shall continue to provide such other perquisites and
benefits as are then being provided pursuant to Sections 5(c), 6 and 9, subject
only to the requirements of any plan or agreement under which such perquisites
or benefits are provided, for the remaining term of this Agreement (the
"Severance Period").

                                       4
<PAGE>

                  d. If (i) the term of this Agreement expires pursuant to
Section 2 hereof, (ii) this Agreement is not renewed or replaced and (iii)
Employee's employment with Employer ceases, other than for cause as defined
herein, then, in such event, Employer shall make a severance payment to Employee
equal to the Salary paid to Employee during the last year of the term of this
Agreement, payable at Employer's discretion either in a lump sum or in 24 equal
semi-monthly installments. The period during which such payments are made
pursuant to this Section 11(d) or, if such payment is made in a lump sum, the
one (1) year period following termination of this Agreement shall be deemed the
Severance Period. Notwithstanding the above, in lieu of making the severance
payment described in this Section 11(d), Employer may release Employee from the
covenant set forth in Section 14 hereof.

         12. INCAPACITY; ILLNESS; DISABILITY. If at any time during the term of
this Agreement, and Employee's employment hereunder, Employee shall, as the
result of mental or physical incapacity, illness or disability, be unable or
fail to perform reasonably his duties and responsibilities provided for herein,
Employer shall nevertheless be obligated to continue to meet all of its
obligations hereunder to Employee unless and until such time as Employer shall
terminate this Agreement pursuant to Section 10(b) hereof; provided, however,
that the amount of any disability insurance benefits which Employee may be
entitled to receive from any source shall be deducted from the portion of the
Salary to be paid by Employer to Employee.

         13. CONFIDENTIALITY.

                  a. Employee agrees that, both during the term of this
Agreement and after the termination of this Agreement, Employee will hold in a
fiduciary capacity for the benefit of Employer, and shall not, directly or
indirectly, use or disclose, except as authorized by Employer in connection with
the performance of his duties, any Confidential Information (as defined below)
that Employee may have or acquire (whether or not developed or compiled by
Employee and whether or not Employee has been authorized to have access to such
Confidential Information) during the term of this Agreement; provided that the
foregoing shall not prohibit the discussion of Confidential Information with an
attorney representing Employee in connection with a dispute between Employee and
Employer to the extent necessary to resolve such dispute. The term "Confidential
Information" as used in this Agreement shall mean and include any material
information, data and know-how relating to the Business of Employer that is
disclosed to Employee by Employer or known by him as a result of his
relationship with Employer and not generally within the public domain (whether
constituting a trade secret or not), including without limitation, the
following: financial information, supply and service information, marketing
information, personnel information, customer information and information with
respect to any corporate affairs that Employer treats as confidential.

         The term "Confidential Information" does not include information that
has become generally available to the public by the act of Employer or by the
act of one who has the right to disclose such information without violating any
right of Employer or the customer to which such information pertains.

                                       5
<PAGE>

         Nothing in this Section 13 shall prevent Employee from disclosing any
Confidential Information to the extent such disclosure is required by law or any
order of a court or government authority with jurisdiction.

                  b. The covenant contained in this Section 13 shall survive the
termination of Employee's employment with Employer for any reason for a period
of two (2) years; provided, however, that with respect to those items of
Confidential Information which constitute trade secrets under applicable law,
Employee's obligations of confidentiality and non-disclosure as set forth in
this Section 13 shall continue to survive after said two (2) year period to the
greatest extent permitted by applicable law. These rights of Employer are in
addition to those rights Employer has under the common law or applicable
statutes for the protection of trade secrets.

         14. COVENANT NOT TO COMPETE. Employee agrees that he will not engage or
participate in any business that competes with the Business of Employer in any
city or county within the United States in which the Employer is then engaging
and continues to engage in its Business, whether as employee, employer,
consultant, agent, principal, partner, stockholder, corporate officer, director,
or other representative capacity, at any time during Employee's employment with
Employer and during the applicable Severance Period as defined in Section 11(c)
or (d) of this Agreement. Notwithstanding the foregoing, Employee may hold an
investment representing a less than 5% interest in any publicly held entity
engaging in a business that competes with the Business of Employer and may
continue to own a less than 5% interest in STI Holding Corporation, a Delaware
company. In addition, in the event Employee's employment is terminated by
Employer for cause as set forth in Section 10(a) hereof, Employee shall be
subject to the covenant not to compete set forth in this Section 14 for a period
of two years following the date of termination. In the event that Employee
violates the covenant contained in this Section 15, Employer may, in addition to
any other remedies available, withhold severance payments due under Section
11(c) or (d). Further, upon termination of Employee's employment with Employer
in connection with the expiration of the term of this Agreement, Employer may
release Employee from this covenant not to compete in lieu of making the
severance payments described in Section 11(d) hereof. In the event any court
shall refuse to enforce any portion of the covenant set forth in this Section
14, then such unenforceable portion shall be deemed eliminated and severed from
said contract for the purposes of said court's proceedings to the extent
necessary to permit the remaining portions of the covenant to be enforced.

         15. COVENANTS AGAINST OTHER ACTIONS DAMAGING EMPLOYER. Employee agrees
that he will not, at any time during his employment with Employer and for the
period that the covenant set forth in Section 14 above applies (the "Non-Compete
Period"), for himself or on behalf of or in conjunction with any third party
solicit any employee of Employer or its subsidiaries to leave such employment;
provided that the posting by Employee or nay entity with which Employee is
involved of general advertisements soliciting employees shall not constitute the
solicitation of any employee of Employer or its subsidiaries. Employee further
agrees that, during the Non-Compete Period, he will not directly or indirectly,
on his own behalf or in the service of or on behalf of

                                       6
<PAGE>

others, solicit, divert or appropriate, or attempt to solicit, divert or
appropriate, to any competing business, any customers of Employer or its
subsidiaries. If, during the term of this agreement, Employee is engaged in or
associated with the planning or implementing of any project, program or venture
involving Employer and a third party or parties (a "Venture"), or any
discussions, analysis or negotiations with respect to an investment in, merger,
acquisition or purchase, directly or indirectly, of the stock, assets, or
business of any entity (an "Acquisition"), all rights in the Venture and the
Acquisition and any opportunity to make any investment in the entity to be so
acquired (the "Target") shall belong to Employer and shall constitute a
corporate opportunity belonging exclusively to Employer. Except as approved by
the Board, Employee shall not be entitled to any interest in any such Venture or
to invest or solicit any third party to invest in the Target or consummate the
Acquisition, or to any commission, finder's fee or other compensation in
connection therewith other than any Salary paid to Employee for performance of
his duties in the ordinary course of business. In the event any court shall
refuse to enforce any portion of the covenants set forth in this Section 15,
then such unenforceable portion shall be deemed eliminated and severed from said
contract for the purposes of said court's proceedings to the extent necessary to
permit the remaining portions of the covenant to be enforced.

         16. ARBITRATION. Any dispute or controversy between the parties under
this Agreement shall exclusively be referred to binding, non-appealable
arbitration in accordance with the procedures set forth in Exhibit A hereto and
without recourse to any litigation except as set forth in Exhibit A. Each party
hereby irrevocably submits itself to a personal jurisdiction in Miami, Florida,
for the purpose of such arbitration proceedings, and/or any suits to confirm the
same. Pending the completion of any arbitration proceedings, payments not in
dispute shall continue to be made and obligations not in dispute shall continue
to be performed.

         17. NO DELEGATION. Employee shall not delegate his employment
obligations pursuant to this Agreement to any other person without the prior
consent of the Board.

         18. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of Florida, without reference to the
conflicts of laws principles thereof.

         19. TERMINATION OF PRIOR AGREEMENT. The Consulting Agreement by and
between Employer and Employee dated June 10, 1997 is hereby terminated and
superseded by this Agreement.

         20. ENTIRE AGREEMENT. This Agreement constitutes the entire agreement
between the parties hereto and supersedes all prior agreements, understandings
and arrangements, both oral and written, between the parties hereto with respect
to the subject matter hereof. This Agreement may not be modified in any way
unless in writing signed by both Employer and Employee.

         21. NOTICES. Any notices required or permitted to be given under this
Agreement shall be in writing and shall be deemed to have been duly given when

                                    EXHIBIT A

                             ARBITRATION PROCEDURES

         a. If a dispute or controversy arises, the parties hereto shall attempt
in good faith to resolve such dispute or controversy promptly by negotiation.
Any such dispute or controversy which has not been resolved by negotiation
within thirty (30) days after the initiation of discussions shall be resolved by
binding arbitration in accordance with the then current CPR Rules for
Non-Administered Arbitration of Business Disputes. Unless the parties agree
otherwise, the arbitration shall be conducted in Miami, Florida, by a panel of
three arbitrators. The disputing parties shall each select one arbitrator, and
the arbitrators so selected shall select an attorney as the third arbitrator. If
the arbitrators selected by the disputing parties fail to agree on the third
arbitrator within thirty (30) days of the date this arbitration provision
becomes operative, any person involved may request CPR to make the appointment
in accordance with its applicable rules.

         b. The arbitrators shall decide the issues submitted to them in
accordance with the provisions and commercial purposes of this Agreement;
provided that, all substantive questions of law shall be determined under the
laws of the State of Florida (without regard to its principles of conflicts of
laws).

         c. The arbitration shall be governed by the United States Arbitration
Act, 9 U.S.C. Section 1, ET SEQ., and judgment upon the award rendered by the
arbitrators may be entered by any court having jurisdiction thereof. The
arbitrators may grant any remedy or relief which is just and equitable,
including injunctive relief or specific performance.

         d. The parties hereto agree to facilitate the arbitration by: (i)
making available to one another and to the arbitrators for examination,
inspection and extraction all documents, books, records and personnel under
their control if determined by the arbitrators to be relevant to the dispute;
(ii) participating in reasonable discovery, including oral depositions; (iii)
conducting arbitration hearings to the greatest extent possible on successive
days; and (iv) observing strictly the time periods established by the Rules or
by the arbitrators for submission of evidence or briefs.

         e. Initially, the disputing parties shall each pay one-half of the
costs (excluding attorneys' fees) of any arbitration; provided, however, that
the arbitrators shall divide all costs (excluding attorneys' fees) incurred in
conducting the arbitration in their final award in accordance with what they
deem just and equitable under the circumstances, and any party who is allocated
in excess of one-half of such costs shall reimburse the other for such excess
costs.

         f. Notwithstanding the exclusivity of the dispute resolution procedures
specified herein, a party hereto, without prejudice to such procedures, may file
a complaint or seek a preliminary injunction or other provisional judicial
relief if in its sole judgment such action is

                                       11
<PAGE>

necessary to avoid irreparable damage or to preserve the status quo. Despite any
such action, the parties shall continue to participate in good faith in the
procedures specified herein.
