services to the best of his ability, and use his best efforts to promote the

the individual and Company performance goals established in accordance with the

any, as the Company shall from time to time determine.

Bonus Period in which his death occurs, as calculated pursuant to the


                                       38

   4

terms of the Incentive Compensation Plan; provided that, the goals under the
Incentive Compensation Plan for each period used in the calculation of the
Executive's Incentive Compensation shall be based on: (i) the portion of the
Bonus Period through the end of the Bonus Period in which the Executive's death
occurs, and (ii) unaudited financial information prepared in accordance with
generally accepted accounting principles, applied consistently with prior
periods. The Company shall have no further liability hereunder other than for:

                  5.4      Termination Not for Cause. In the case of termination
of Executive's employment by Company, without Cause, the Company shall: (a) pay
to the Executive any unpaid Base Salary through the effective date of

such termination occurs, as calculated pursuant to the Incentive Compensation
Plan; provided that the goals under the Incentive Compensation Plan for each
period used in the calculation of the Executive's Incentive Compensation, shall
be based on: (i) the portion of the Bonus Period through the end of the Bonus
Period in which such termination occurs and (ii) unaudited financial information
prepared in accordance with generally accepted accounting principles, applied
consistently with prior periods. The Company shall have no further liability
hereunder other than for: (x) reimbursement for reasonable business expenses

         6.       Restrictive Covenants.

                  6.1      Non-competition. At all times while the Executive is
employed by the Company and (i) for a two (2) year period after the termination
of the Executive's employment with the Company for Cause or if Executive
voluntarily resigns, or (ii) for a one (1) year period after the termination of
the Executive's employment with the Company any of other reason, the Executive
shall not, directly or indirectly, act alone or as a partner, joint venturer,
officer, director, member, employee, consultant, agent, independent contractor
or shareholder of, or lender to, any company or business (a "Competitor") whose
products or services compete with (i) the business of Company (for this purpose,
any business that engages or intends to engage in the development,
manufacturing, marketing, licensing, or sale of software applications or
products that have been developed and/or marketed, or are in the process of
being developed and/or marketed, by Company (the "Computer Products") at any
time during the time the Executive was or is employed by the Company shall be
deemed to be in competition with the Company and a Competitor) (for purposes of
this Section 6.1, collectively the "Business") or (ii) the Computer Products or
any upgrades, enhancements, or other releases, modifications or customizations
thereof, or otherwise which enterprise is the same as or similar to the
Business; provided, however, that, the beneficial ownership of less than five
percent (5%) of the shares of stock of any corporation having a class of equity
securities actively traded on a national securities exchange or over-the-counter
market shall not be deemed, in and of itself, to violate the prohibitions of
this Section.

                  6.2      Nondisclosure. The Executive shall not at any time
divulge, communicate, use to the detriment of the Company or for the benefit of
any other person or persons, or misuse in any way, any Confidential Information
(as hereinafter defined) pertaining to the business of the Company. Any


                                       39

   5

Confidential Information or data now or hereafter acquired by the Executive with
respect to the business of the Company (which shall include, but not be limited
to, information concerning the Company's financial condition, prospects,
technology, 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 not generally known, about the Company or its
business. Notwithstanding the foregoing, nothing herein shall be deemed to
restrict the Executive from disclosing Confidential Information to the extent
required by law.

                  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 after the termination of the Executive's employment with the Company for
any reason, the Executive shall not, directly or indirectly, for himself or for
any other person, firm, corporation, partnership, association or other entity:
(a) employ or attempt to employ or enter into, or knowingly permit any company
or business directly or indirectly controlled by such Executive, to employ or
attempt to employ or enter into, any contractual arrangement with any then
current or former management personnel, computer programmer or similarly skilled
employee of the Company, unless such employee or former employee has not been
employed by the Company for a period in excess of six (6) months, and/or (b)
call on or solicit any of the actual or targeted prospective clients of the
Company on behalf of any Competitor, 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 clients, 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 take such further actions, including execution and delivery of
instruments of conveyance, as may be appropriate to give full and 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 the 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      Acknowledgment by Executive. The Executive
acknowledges and confirms that the length of the term of the provisions of this
Section 6 and the geographical restrictions contained in Section 6.1 are fair
and reasonable and not the result of overreaching, duress or coercion of any
kind. The Executive further acknowledges and confirms that his full, uninhibited
and faithful observance of each of the covenants contained in this Section 6
will not cause him any undue hardship, financial or otherwise. 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 Section 6.

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

                  6.8      Extension of Time. If the Executive shall be in
violation of any provision of this Section 6, then each time limitation set
forth in this Section 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 Section 6 shall be extended for a period of time equal to the
pendency of such proceeding including all appeals by the Executive.

                  6.9      Survival. The provisions of this Section 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 Section 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 Section 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.       Successors and Assignment. This Agreement shall be binding
upon and inure to the benefit of the Executive and his/her heirs and personal
representatives and the Company and its successors, assigns and legal
representatives. This Agreement is for the personal services of the Executive.
The benefits hereunder are personal to the Executive and are not assignable or
transferable by the Executive. This Agreement shall not be assigned by the
Company to any entity or person without the prior written consent of the
Executive, provided that it may be assigned by the Company without the prior
written consent of the Executive to an entity or person which acquires all or
substantially all of the assets of the Company by purchase, merger or
consolidation. In the event of any permitted assignment, all references to the
Company in this Agreement shall be deemed to mean such assignee, but the Company
shall not be released from its obligations under this Agreement by virtue of the
assignment of this Agreement.

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

         10.      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 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.

         11.      Notices. All notices required or permitted to be given
hereunder shall be in writing and shall be personally delivered by courier, sent
by registered or certified mail, return receipt requested or sent by confirmed
facsimile transmission addressed as set forth herein. Notices personally
delivered, sent by facsimile or sent by overnight courier shall be deemed given
on the date of delivery and notices mailed in


                                       41
   7

accordance with the foregoing shall be deemed given upon the earlier of receipt
by the addressee, as evidenced by the return receipt thereof, or three (3) days
after deposit in the U.S. Mail. Notice shall be sent: (a) if to the Company,
addressed to 1000 Business Center Drive, Lake Mary, Florida, 32746, Attention:
President, and (b) if to the Executive, to his address as reflected on the
payroll records of the Company, or to such other address as either party hereto
may from time to time give notice of to the other.

         12.      Benefits; Binding Effect. This Agreement shall be for the
benefit of and binding upon the parties hereto and their respective heirs,
personal representatives, legal representatives, successors and, where
applicable, assigns, including, without limitation, any successor to the
Company, whether by merger, consolidation, sale of stock, sale of assets or
otherwise.

         13.      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.

         14.      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.

         15.      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.

         16.      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.

         17.      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.

         IN WITNESS WHEREOF, the undersigned have executed this Agreement as of
the date first above written.
