            5.1 Termination for Cause. The Company shall at all times have the

         For purposes of this Agreement, the term "Cause" shall mean (i) an
         action or omission of the Executive which constitutes a willful and
         material breach of, or failure or refusal (other than by reason of his

         in connection with the performance of the Executive's duties hereunder,
         (v) insubordination or other refusal to adhere to Company policy or the
         instructions of a superior, or (vi) negligence by commission or
         omission that results in injury or damage to the Company. Any
         termination for Cause shall be made in writing to the Executive, which
         notice shall set forth in detail all acts or omissions upon which the
         Company is relying for such termination. Upon any termination pursuant
         to this Section 5.1, the Company shall only be obligated to pay to the
         Executive his Base Salary to the date of termination. The Company shall
         have no further liability hereunder (other than for reimbursement for
         reasonable business expenses incurred prior to the date of termination,
         subject, however, to the provisions of Section 4.1).

            5.2 Disability. The Company shall at all times have the right, upon
         written notice to the Executive, to terminate the Term of Employment,
         if the Executive shall become entitled to benefits under the Company's
         group disability policy or any individual disability policy then in
         effect, or, if the Executive shall as the result of mental or physical
         incapacity, illness or disability, become unable to perform his
         obligations hereunder for a period of 90 days in any 12-month period.
         The Company shall have sole discretion based upon competent medical
         advice to determine whether the Executive continues to be disabled.
         Upon any termination pursuant to this Section 5.2, the Company shall
         (i) pay to the Executive any unpaid Base Salary through the effective
         date of termination specified in such notice, (ii) pay to the Executive
         a severance payment equal to one month of the Executive's Base Salary
         at the time of the termination of the Executive's employment with the
         Company. The Company shall have no further liability hereunder (other
         than for reimbursement for reasonable business expenses incurred prior
         to the date of termination, subject, however to the provisions of
         Section 4.1).

            5.3 Death. Upon the death of the Executive during the Term of
         Employment, the Company shall pay to the estate of the deceased
         Executive any unpaid Base Salary through the Executive's date of death.
         The Company shall have no further liability hereunder (other than for
         reimbursement for reasonable business expenses incurred prior to the
         date of the Executive's death, subject, however to the provisions of
         Section 4.1).

            5.4 Termination Without Cause. At any time the Company shall have
         the right to terminate the Term of Employment by written notice to the
         Executive. Upon any termination pursuant to this Section 5.4 (that is
         not a termination under any of Sections 5.1, 5.2, 5.3, 5.5 or 5.6), the
         Company shall (i) pay to the Executive any unpaid Base Salary through
         the effective date of termination specified in such notice, (ii)
         continue to pay the Executive's Base Salary for a period (the
         "Continuation Period") of six (6) months from the effective date of
         termination hereunder, provided, however, Executive shall have been
         employed by Company for a period of at least one hundred eighty (180)
         days to be eligible for such payment, (iii) continue to provide the
         Executive with the benefits he/she was receiving under Sections 4.2 and
         4.4 hereof (the "Benefits") through the end of the Continuation Period
         in the manner and at such times as the Incentive Compensation or
         Benefits otherwise would have been payable or


                                      -3-


provided to the Executive, provided, however, Executive shall have been
employed by Company for a period of at least one hundred eighty (180) days to
be eligible for such Benefits or payment of the cash value of such Benefits, as
set forth below. In the event that the Company is unable to provide the
Executive with any Benefits required hereunder by reason of the termination of
the Executive's employment pursuant to this Section 5.4, then the Company shall
pay the Executive cash equal to the value of the Benefit that otherwise would
have accrued for the Executive's benefit under the plan, for the period during
which such Benefits could not be provided under the plans. The Company's good
faith determination of the amount that would have been contributed or the value
of any Benefits that would have accrued under any plan shall be binding and
conclusive on the Executive. For this purpose, the Company may use as the value
of any Benefit the cost to the Company of providing that Benefit to the
Executive. Further, the vesting of the Executive's Stock Options, if any, shall
be subject to the terms of the Stock Option Plan. The Company shall have no
further liability hereunder (other than for (x) reimbursement for reasonable
business expenses incurred prior to the date of termination, subject, however,
to the provisions of Section 4.1, and (y) payment of compensation for unused
vacation days accumulated in accordance with the Company's then general policy).

         5.5      Termination by Executive.

                  (a)      The Executive shall at all times have the right,
upon sixty (60) days written notice to the Company, to terminate the Term of
Employment.

                  (b)      Upon termination of the Term of Employment pursuant
to this Section 5.5 (that is not a termination under Section 5.6) by the
Executive without Good Reason, the Company shall pay to the Executive any
unpaid Base Salary through the effective date of termination specified in such
notice. The Company shall have not further liability hereunder (other than for
reimbursement for reasonable business expenses incurred prior to the date of
termination, subject, however, to the provisions of Section 4.1). At the
Company's sole option, upon receipt of notice from the Executive pursuant to
this Section, the Company may immediately terminate the Term of Employment, in
which case, in addition to the covenants set forth above, the Company shall pay
the Executive 60 days of Base Salary.

                  (c)      Upon termination of the Term of Employment pursuant
to this Section 5.5 (that is not a termination under Section 5.6) by the
Executive for Good Reason, the Company shall pay to the Executive the same
amounts that would have been payable by the Company to the Executive under
Section 5.4 of this Agreement if the Term of Employment had been terminated by
the Company without Cause. The Company shall have no further liability
hereunder.

                  (d)      For purposes of this Agreement, "Good Reason" shall
mean (i) the assignment to the Executive of any duties or responsibilities
inconsistent in any respect with the Executive's position or a similar position
in the Company or one of its subsidiaries, as contemplated by Section 1.2 of
this Agreement, or any other action by the Company which results in a
substantial and compelling diminution in such position, authority, duties or
responsibilities, excluding for this purpose an isolated, insubstantial and
inadvertent action not taken in bad faith and which is remedied by the Company
promptly after receipt of notice thereof given by the Executive; (ii) any
failure by the Company to comply with any of the provisions of Article 3 of
this Agreement, other than an isolated, insubstantial and inadvertent failure
not occurring in bad faith and which is remedied by the Company promptly after
receipt of notice thereof given by the Executive; (iii) the Company's requiring
the Executive to be based at any office or location outside of the area for
which Executive was originally hired to work except for travel reasonably
required in the performance of the Executive's responsibilities. For purposes of
this Section 5.5(d), any good faith determination of "Good Reason" made by the
Board shall be conclusive.


                                      -4-



         5.6      Change in Control of the Company.

immediately preceding the year in which his employment terminates, plus (y) the
value of the portion of his benefits under any savings, pension, profit sharing
or deferred compensation plans that are forfeited under those plans by reason of
the termination of his employment hereunder. The Company shall have no further
liability hereunder (other than for (1) reimbursement for reasonable business
expenses incurred prior to the date of termination, subject, however, to the
provisions of Section 4.1, and (2) payment of compensation for unused vacation
days that have accumulated during the calendar year in which such termination
occurs).

                  (b)      For purposes of this Agreement, the term "Change in

Executive's employment with the Company for any reason (other than by the
Company without Cause (as defined in Section 5.1 hereof) or by the Executive
for Good Reason (as defined in Section 5.5(d) hereof)), the Executive shall not,

customers, suppliers, sources of leads and methods of doing business) shall be
deemed a valuable, special and unique asset of the Company that is received by
the Executive in confidence and as a fiduciary, and Executive shall remain a
fiduciary to the Company with respect to all of such information. For purposes
of this Agreement, "Confidential Information" means information disclosed to the
Executive or known by the Executive as a consequence of or through his
employment by the Company (including information conceived, originated,
discovered or developed by the Executive) prior to or after the date hereof, and

                 6.3 Nonsolicitation of Employees and Clients. At all times
while the Executive is employed by the Company and for a two (2) year period

reason, the Executive shall not, directly or indirectly, for himself or for any
other person, firm, corporation, partnership, association or other entity (a)

employee has not been employed by the Company for a period in excess of six
months, and/or (b) call on or solicit any of the actual or targeted prospective


                                      -6-

business competitive with the business of the Company, nor shall the Executive
make known the names and addresses of such clients or any information relating
in any manner to the Company's trade or business relationships with such
customers, other than in connection with the performance of Executive's duties
under this Agreement.

         6.4  Ownership of Developments. All copyrights, patents, trade
secrets, or other intellectual property rights associated with any ideas,
concepts, techniques, inventions, processes, or works of authorship developed
or created by Executive during the course of performing work for the Company or
its clients (collectively, the "Work Product") shall belong exclusively to the
Company and shall, to the extent possible, be considered a work made by the
Executive for hire for the Company within the meaning of Title 17 of the United
States Code. To the extent the Work Product may not be considered work made by
the Executive for hire for the Company, the Executive agrees to assign, and
automatically assign at the time of creation of the Work Product, without any
requirement of further consideration, any right, title, or interest the
Executive may have in such Work Product. Upon the request of the Company, the
Executive shall further actions, including execution and delivery of
instruments of conveyance, as may be appropriate to give full proper effect to
such assignment.

         6.5  Books and Records. All books, records, and accounts relating in
any manner to the customers or clients of the Company, whether prepared by the
Executive or otherwise coming into the Executive's possession, shall be
exclusive property of the Company and shall be returned immediately to the
Company on termination of the Executive's employment hereunder or on the
Company's request at any time.

         6.6  Definition of Company. Solely for purposes of this Article 6,
the term "Company" also shall include any existing or future subsidiaries of
the Company that are operating during the time periods described herein and any
other entities that directly or indirectly, through one or more intermediaries,
control, are controlled by or are under common control with the Company during
the periods described herein.

         6.7  Acknowledgment by Executive. The Executive acknowledges and
confirms that (a) the restrictive covenants contained in this Article 6 are
reasonably necessary to protect the legitimate business interest of the
Company, and (b) the restrictions contained in this Article 6 (including
without limitation the length of the term of the provisions of this Article 6)
are not overbroad, overlong, or unfair and are not the result of overreaching,
duress or coercion of any kind. The Executive further acknowledges and
confirms that this full, uninhibited and faithful observance of each of the
covenants contained in this Article 6 will not cause him any undue hardship,
financial or otherwise, and that enforcement of each of the covenants contained
herein will not impair his ability to obtain employment commensurate with his
abilities and on terms fully acceptable to him or otherwise to obtain income
required for the comfortable support of him and his family and the satisfaction
of the needs of his creditors. The Executive acknowledges and confirms that his
special knowledge of the business of the Company is such as would cause the
Company serious injury or loss if he were to use such ability and knowledge to
the benefit of a competitor or were to compete with the Company in violation of
the terms of this Article 6. The Executive further acknowledges that the
restrictions contained in this Article 6 are intended to be, and shall be, for
the benefit of and shall be enforceable by, the Company's successors and
assigns.

         6.8  Reformation by Court. In the event that a court of competent
jurisdiction shall determine that any provision of this Article 6 is invalid or
more restrictive than permitted under the governing law of such jurisdiction,
then only as to enforcement of this Article 6 within the jurisdiction of

such court, such provision shall be interpreted and enforced as if it provided
for the maximum restriction permitted under such governing law.

                  6.9      Extension of Time. If the Executive shall be in
violation of any provision of this Article 6, then each time limitation set
forth in this Article 6 shall be extended for a period of time equal to the
period of time during which such violation or violations occur. If the Company
seeks injunctive relief from such violation in any court, then the covenants set
forth in this Article 6 shall be extended for a period of time equal to the
pendency of such proceeding including all appeals by the Executive.

                  6.10     Survival. The provisions of this Article 6 shall
survive the termination of this Agreement, as applicable.

         7.       Injunction. It is recognized and hereby acknowledged by the
parties hereto that a breach by the Executive of any of the covenants contained
in Article 6 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 Executive 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 Article 6 of this Agreement by the Executive 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.

         8.       Assignment. Neither party shall have the right to assign or
delegate his rights or obligations hereunder, or any portion thereof, to any
other person.

         9.       Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Florida.

         10.      Section 162(m) Limits. Notwithstanding any other provision of
this Agreement to the contrary, if and to the extent that any remuneration
payable by the Company to the Executive for any year would exceed the maximum
amount of remuneration that the Company may deduct for that year under Section
162(m) ("Section 162(m)") of the Internal Revenue Code of 1986, as amended (the
"Code"), payment of the portion of the remuneration for that year that would
not be so deductible under Section 162(m) shall, in the sole discretion of the
Board, be deferred and become payable at such time or times as the Board
determines that it first would be deductible by the Company under Section
162(m), with interest at the "short-term applicable rate" as such term is
defined in Section 1274(d) of the Code. The limitation set forth under this
Section 10 shall not apply with respect to any amounts payable to the Executive
pursuant to Article 5 hereof.

         11.      Entire Agreement. This Agreement constitutes the entire
agreement between the parties hereto with respect to the subject matter hereof
and, upon its effectiveness, shall supersede all prior agreements,
understandings and arrangements, both oral and written, between the Executive
and the Company (or any of its affiliates) with respect to such subject matter.
This Agreement may not be modified in any way unless by a written instrument
signed by both the Company and the Executive.

give notice of to the other.

         14. Severability. The invalidity of any one or more of the words,
phrases, sentences, clauses or sections contained in this Agreement shall not
affect the enforceability of the remaining portions of this Agreement or any
part thereof, all of which are inserted conditionally on their being valid in
law, and, in the event that any one or more of the words, phrases, sentences,
clauses or sections contained in this Agreement shall be declared invalid, this
Agreement shall be construed as if such invalid word or words, phrase or
phrases, sentence or sentences, clause or clauses, or section or sections had
not been inserted. If such invalidity is caused by length of time or size of
area, or both, the otherwise invalid provision will be considered to be
reduced to a period or area which would cure such invalidity.

         15. Waivers. The waiver by either party hereto of a breach or violation
of any term or provision of this Agreement shall not operate nor be construed as
a waiver of any subsequent breach or violation.

         16. Damages. Nothing contained herein shall be construed to prevent the
Company or the Executive from seeking and recovering from the other damages
sustained by either or both of them as a result of its or his breach of any term
or provision of this Agreement. In the event that either party hereto brings
suit for the collection of any damages resulting from, or the injunction of any
action constituting, a breach of any of the terms or provisions of this
Agreement, then the party found to be at fault shall pay all reasonable court
costs and attorneys' fees of the other.

         17. Section Headings. The section headings contained in this Agreement
are for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

         18. No Third Party Beneficiary. Nothing expressed or implied in this
Agreement is intended, or shall be construed, to confer upon or give any person
other than the Company, the parties hereto and their respective heirs, personal
representatives, legal representatives, successors and assigns, any rights or
remedies under or by reason of this Agreement.

         19. Indemnification. The indemnification obligations of the Company to
Executive shall be in accordance with the Company's standard indemnity
agreement.

an award of reasonable attorneys' fees and costs incurred in connection
therewith.

         21. Controlling Agreement. This Agreement shall supercede, replace and
be considered a novation of any prior agreements, contracts, offer letters, oral
promises and the like regarding compensation, employment, benefits or any other
subject addressed herein.
