     6.   Termination of Employment.
          -------------------------

          (a)  Permanent Disability. In the event of the Permanent Disability
               --------------------
(as defined below) of Employee, the Company, in its sole discretion, may elect
either (i) to the extent feasible consistent with Employee's mental and physical
condition and consistent with applicable law, to reassign Employee to other
duties within the Company that Employee is able to perform despite his Permanent
Disability at the compensation and benefit levels commensurate with Employee's
reassigned duties, unless that compensation level is less than the amount
payable in the event of a termination pursuant to the following sentence, or
(ii) to terminate this Agreement and Employee's employment hereunder. In the
event that the Company elects to terminate Employee as provided in clause (ii)
above, the Company shall, subject to following sentence, pay to Employee (A)
within sixty (60) days after the date of such termination, all amounts of Base
Salary accrued pursuant to Section 4 above prior to the date of such
termination, and (B) compensation on the basis of 65% of the then current Base
Salary for the first ninety (90) days of such Permanent Disability and,
thereafter, compensation on the basis of 50% of the then current Base Salary
through the end of the Permanent Disability period. This benefit may be provided
by the Company to Employee through the purchase of a disability insurance policy
that is contingent upon the insurability of Employee. Notwithstanding the
foregoing, all payments hereunder shall end upon the earlier to occur of
Executive's attaining the age of sixty-five (65) and the cessation of such
Permanent Disability (whether as a result of recovery, rehabilitation, death or
otherwise), and, thereafter, the Company shall have no further obligations to
Employee


under this Agreement. Additionally, if prior to the termination of the Company's
obligation to make payments to Employee pursuant to this Section 6(a) Employee
receives compensation for services rendered, whether as an employee or
otherwise, such compensation shall reduce the payments due under this Section
6(a), dollar for dollar. Employee shall promptly inform the Company of all such
compensation received by him on a monthly basis during such period.

          (b)  Death. In the event of Employee's death, the Company shall pay to
               -----
Employee's personal representative (on behalf of Employee's estate), within
sixty (60) days after the Company receives written notice of such
representative's appointment, all amounts of Base Salary accrued pursuant to
Section 4 above as of the date of Employee's death and any amounts payable
pursuant to Section 5(c)(vi), which payment shall constitute full and complete
satisfaction of the Company's obligations hereunder except for any additional
payments subsequently due with respect to the exercise of options granted
pursuant to Section 5.  Employee's dependents shall also be entitled to any
continuation of health insurance coverage rights, if any, under applicable law.

          (c)  Termination for Cause or Voluntary Termination Without Good
               -----------------------------------------------------------
Reason. The Company may in its sole discretion terminate this Agreement and
- ------
Employee's employment with the Company for Cause (as defined in Section 7(a)
below) at any time with 30 days advance notice to Employee.  If Employee's
employment is terminated for Cause, or if Employee Voluntarily Terminates (as
defined in Section 7(b) below) his employment with the Company without Good
Reason (as defined in Section 7(c) below), the Company shall promptly pay to
Employee all amounts of Base Salary accrued pursuant to Section 4 above through
the date of termination (but not Bonus Compensation), whereupon the Company
shall have no further obligations to Employee under this Agreement. Employee
and his dependents shall also be entitled to any continuation health insurance
coverage rights, if any, under applicable law.  Without waiving any rights the
Company or any of its affiliates may have hereunder or otherwise, the Company
hereby expressly reserves its right to proceed against Employee for damages in
connection with any claim or cause of action that the Company may have arising
out of or related to Employee's employment hereunder.  In the event the Company
terminates Employee's employment for Cause or Employee voluntarily terminates
his employment without Good Reason, all unvested options and other awards
granted to Employee under the Stock Plan, as Bonus Compensation or otherwise
shall be cancelled and forfeited by Employee.


          (d)  Termination Without Cause; Voluntary Termination With Good
               ----------------------------------------------------------
Reason. Subject to the penultimate sentence of this paragraph, the Company may
- ------
terminate this Agreement and Employee's employment with the Company without
Cause at any time, with or without notice, for any reason or no reason (and no
reason need be given). Employee may terminate this Agreement and Voluntarily
Terminate his employment with the Company with Good Reason upon thirty (30)
days' prior written notice to the Company, provided that the Company does not
correct the circumstances giving Employee Good Reason during such thirty (30)
day period. In the event Employee's employment with the Company is terminated
pursuant to this Section 6(d): (i) the Company shall immediately pay to Employee
in a lump sum all amounts of Base Salary for the entire length of the Term, (ii)
Employee shall be relieved of his obligations under Sections 1 and 3 hereof, and
(iii) Employee shall be free to seek other employment subject to the terms of
Sections 8, 9, 10 and 11 hereof. Employee and his dependents shall also be
entitled to any continuation health insurance coverage rights, if any, under
applicable law.

          (e)  Termination Obligations.
               -----------------------

     (i)  Employee hereby acknowledges and agrees that all personal property and

returned to the Company upon termination of the Employee's employment. The term
"personal property" includes, without limitation, all books, manuals, records,
reports, notes, contracts, requests for proposals, bids, lists, blueprints, and
other documents, or materials, or copies thereof (including computer files), and
all other proprietary information relating to the business of the Company or any
of its affiliates. Following termination, Employee will not retain any written
or other tangible material containing any proprietary information of the Company
or any of its affiliates.

deemed to have resigned from all offices and directorships then held with the
Company and each of its affiliates.

          (iii)  The representations and warranties contained herein made by
either Employer and Employee and Employee's obligations under Sections 6(e), 8,
9, 10 and 11 shall survive termination of the Employment Period and the
expiration of this Agreement.


          (iv)   If the common Closing price of the stock of Employer (or any
successor to Employer) equals or exceeds 100% of the exercise price of any
options granted pursuant to Section 4(b) hereof for 5 consecutive trading days
after the termination of Employee's employment, any options held by Employee
must be exercised within 90 days after the end of such 5 day period. Any options
which are not exercised at the end of such 90 day period will be forfeited by
Employee.

          (f)    Change of Control.  In the event of a Change of Control (as
                 -----------------
defined below), an amount equal to Employee's Base Salary shall be multiplied by
a factor of 2 and shall be paid by Employer (or its permitted successors) in one
lump-sum within 30 days after the effective date of the Change of Control.  In
addition, if so requested by Employee in writing at least 15 days prior to the
effective date of the Change of Control, Employer (or its permitted successors)
will either repurchase Employee's options within five (5) business days after
the effective date of the Change of Control or will cause employee's options to
be so repurchased at fair market value (as determined by Employer's regular
outside accounting firm).  Employer will give Employee reasonable notice of any
pending Change of Control (to the extent feasible under applicable securities
laws) in the event that Employee is not then employed by Employer.

     duties and responsibilities are materially inconsistent with the type of
     duties and responsibilities of Employee in effect immediately

     law, and such violation has not been cured within sixty (60) days following
     the Company's receipt of written notice thereof, or (v) the Board of

equipment, supplies, facilities or Confidential Information (as defined below)
of Employer was used and that was developed entirely on Employee's own time,
unless (i) the invention relates in any way to or is useful in the business or
products of Employer, or Employer's actual or demonstrably anticipated research
or development, or (ii) results from any work performed by Employee for or on
behalf of Employer.

          (d)  Employee agrees, without further consideration, to (i) promptly
disclose each such Invention to Employer, to Employee's immediate supervisor and
to such other individuals as Employer may direct, (ii) execute and to join
others in executing such applications, assignments and other documents as may be
necessary or convenient to vest in Employer, or its designee, full title to each
such Invention and as may be necessary or convenient to obtain United States and
foreign patents and copyrights thereon, to the extent Employer may so choose in
its sole discretion, (iii) testify in any legal proceeding relative to such
Invention whenever requested to do so by Employer, and (iv) furnish all facts
relating to such Inventions or the history thereof.

          (e)  Employee agrees that he will not at any time, except as
authorized or directed by Employer, publish or disclose any information or
knowledge concerning any Inventions unless disclosure is required by government
regulation, subpoena or other legal process.

     10.  Non-Competition.
          ---------------

          (a)  Employer and Employee recognize that Employee has been retained
to occupy a position that constitutes part of the professional, management and
executive staff of Employer, whose duties will include the formulation and
execution of management policy. Employee, for and in consideration of the
payments, rights and benefits provided herein, agrees that so long as he is
employed by Employer and, if Employer terminates his employment for Cause or if
Employee voluntarily terminates without Good Reason his employment with
Employer, for a period of one (1) year thereafter, Employee shall not (i) work,
(ii) assist, (iii) own any interest, directly or indirectly and whether
individually or as a joint venturer, partner, member, officer, director,
shareholder, consultant, employee or otherwise, in or (iv) make a financial
investment,


whether in the form of equity or debt, in any business that is substantially
competitive with the Business.

          (b)  Notwithstanding the foregoing, nothing herein shall prohibit
Employee from holding five percent (5%) or less of any class of voting
securities of any entity whose equity securities are listed on a national
securities exchange or regularly traded in the over-the-counter market and for
which quotations are readily available on the National Association of Securities
Dealers Automated Quotation system.  In addition, after the termination of
Employee's employment with Employer for any reason, nothing herein shall be
deemed to prohibit Employee from working with or owning an interest in a
professional services firm such as an accounting firm or law firm as long as
Employee does not directly or in a supervisory capacity provide services to any
business that is substantially competitive with the Business.

          (c)  If Employee is terminated for Cause or voluntarily terminates
employment without Good Reason, then upon the termination of Employee's
employment with Employer, and for one (1) year thereafter, Employee shall
immediately notify Employer of each employment or agency relationship entered
into by Employee, and each corporation, proprietorship or other entity formed or
used by Employee, the business of which is directly in competition with the
Business.  The provisions of this Section 10 shall survive termination of this
Agreement for any reason.

          (d)  Employee agrees that the restrictions contained in this Section
10 are reasonable as to time and geographic scope. Employee acknowledges that
Employer is in direct competition with all other companies that provide services
and products similar to Employer's products and services throughout the United
States, Latin America and other markets in which Employer may be conducting the
Business at the time Employee's employment with Employer is terminated, and
because of the nature of the Business, Employee agrees that the covenants
contained in this Section 10 cannot reasonably be limited to any smaller
geographic area.

     11.  Non-Solicitation and Non-Interference.
          -------------------------------------

          (a)  Employee acknowledges that Employer has invested substantial time
and effort in assembling its present staff of personnel.  Employee agrees that
so long as he is employed by Employer and, if Employer terminates his employment
for Cause or if Employee voluntarily terminates without Good Reason his
employment with Employer, for a period of one (1) year


thereafter, Employee shall not either directly or indirectly employ, solicit for
employment, or advise or recommend to any other person that such other person
employ or solicit for employment, any of Employer's employees.

          (b)  Employee acknowledges that all customers of Employer, which
Employee has serviced or hereafter services during Employee's employment by
Employer and all prospective customers from whom Employee has solicited or may
solicit business while in the employ of Employer, shall be solely the customers
of Employer.  Employee agrees that so long as he is employed by Employer and, if
Employer terminates his employment for Cause or if Employee voluntarily
terminates without Good Reason his employment with Employer, for a period of one
(1) year thereafter, Employee shall not either directly or indirectly solicit
business, as to products or services competitive with the Business of Employer,
from any of Employer's customers with whom Employee had contact during his
employment with Employer.

          (c)  Employee agrees that so long as he is employed by Employer and,
if Employer terminates his employment for Cause or if Employee voluntarily
terminates without Good Reason his employment with Employer, for a period of one
(1) year thereafter, Employee shall not either directly or indirectly interfere
with any relationship between Employer and any of its suppliers, clients or
employees. Employee agrees that during such one (1) year period, he will not
influence or attempt to influence any of the customers or clients of Employer
not to do business with Employer.

          (d)  Employee agrees that the restrictions contained in this Section
11 are reasonable as to time and geographic scope because of the nature of the
Business and Employee agrees, in particular, that the geographic scope of this
restriction is reasonable because companies in the same industry as the Business
compete on a nationwide basis. Employee acknowledges that Employer is in direct
competition with all other companies that provide services and products similar
to Employer's products and services on an outsourced basis throughout the United
States, Latin America and other markets in which Employer may be conducting the
Business at the time Employee's employment with Employer is terminated and,
because of the nature of the Business, Employee expressly agrees that the
covenants contained in this Section 11 cannot reasonably be limited to any
smaller geographic area.

     12.  Employment Relationship.  The relationship between Employer and
          -----------------------
Employee is


and shall be specifically limited to an employer/employee relationship. As a
result, nothing contained in this Agreement or relating to any past, present or
future relationship between Employee and Employer (employment or otherwise)
shall be construed as creating any partnership, joint venture,
trustee/beneficiary or other type of fiduciary or business relationship between
the parties.

     13.  Prior Obligations.  Employee represents and warrants that (a) Employee
          -----------------
has no obligation of confidence or other commitments to any previous employer or
any others that conflict with this Agreement or restrict Employee's field of
activities, and (b) no other agreement to which Employee is subject will
conflict with, prevent, be breached by, interfere with or in any manner affect
the terms and conditions of this Agreement.

     14.  Dedication Of Services.  Subject to the provisions of Section 3(b)
          ----------------------
hereof, Employee agrees that while employed with Employer, Employee shall devote
his entire productive time, ability and attention to the business of Employer
during Employer's normal business hours. Employee further agrees that during his
employment by Employer, Employee will not, without Employer's prior written
consent, directly or indirectly engage in any employment, consulting, or other
activity which would conflict with Employee's duties and obligations to
Employer.

     15.  Jurisdiction; Service of Process.  Each of the parties hereto agrees
          --------------------------------
that all any action or proceeding initiated or otherwise brought to judicial
proceedings by either Employee or Employer concerning the subject matter of this
Agreement shall be litigated in the United States District Court for the
Southern District of Florida or, in the event such court cannot or will not
exercise jurisdiction, in the state courts of the State of Florida (the
"Courts"). Each of the parties hereto expressly submits to the jurisdiction and
venue of the Courts and consents to process being served in any suit, action or
proceeding of the nature referred to above either (a) by the mailing of a copy
thereof by registered or certified mail, postage prepaid, return receipt
requested, to his or its address as set forth herein (subject to notice of
change as set forth below) or (b) by serving a copy thereof upon such party's
authorized agent for service of process (to the extent permitted by applicable
law, regardless whether the appointment of such agent for service of process for
any reason shall prove to be ineffective or such agent for service of process
shall accept or acknowledge such service); provided that, to the extent lawful
and practicable, written notice of said service upon said agent shall be mailed
by registered or certified mail, postage prepaid, return receipt requested, to
the party at his or its address as set forth herein. Each party hereto agrees
that such service, to the


fullest extent permitted by law, (i) shall be deemed in every respect effective
service of process upon him or it in any such suit, action or proceeding and
(ii) shall be taken and held to be valid personal service upon and personal
delivery to him or it. Each party hereto waives any claim that the Courts are an
inconvenient forum or an improper forum based on lack of venue or jurisdiction.
Each party shall bear its own costs and attorneys' fees incurred in connection
with any such actions or proceedings.

     16.  Injunctive Relief.  Employee acknowledge that damages would be an
          -----------------
inadequate remedy for Employee's breach of any of the provisions of Sections 8,
9, 10 and/or 11 of this Agreement, and that breach of any of such provisions
will result in immeasurable and irreparable harm to Employer. Therefore, in
addition to any other remedy to which Employer may be entitled by reason of
Employee's breach or threatened breach of any such provision, Employer shall be
entitled to seek and obtain a temporary restraining order, a preliminary and/or
permanent injunction, or any other form of equitable relief from any court of
competent jurisdiction restraining Employee from committing or continuing any
breach of such Sections, without the necessity of posting a bond. It is further
agreed that the existence of any claim or cause of action on the part of
Employee against Employer, whether arising from this Agreement or otherwise,
shall in no way constitute a defense to the enforcement of the provisions of
Sections 8, 9, 10 and/or 11 of this Agreement.

     17.  Indemnification. Employer agrees to indemnify Employee against
          ---------------
liabilities, expenses, and losses that may arise by reason of the Employee's
status as an officer and to advance expenses incurred as a result of any suit,
action, claim or proceeding, whether civil, criminal, investigative, or
administrative, against Employee. In addition, Employer agrees to maintain in
full force and effect, at its own expense, adequate insurance coverage
protecting the Employee and holding the Employee harmless against liabilities,
expenses, and losses arising from any suit, action, claim or proceeding, whether
civil, criminal, investigative, or administrative, made or asserted against the
Employee resulting from the Employee's actions in his official capacity. The
provisions of this Section 17 shall survive termination of this Agreement for
any reason.

     18.  Miscellaneous.

          Employer from time to time, unless another address has been provided
          to Employer in writing by Employee.


          (b)  Governing Law.  This Agreement shall be governed as to its
               -------------
validity and effect by the internal laws of the State of Florida, without regard
to its rules regarding conflicts of law.

          (c)  Successors and Assigns.  This Agreement shall be binding upon and
               ----------------------
shall inure to the benefit of (i) the heirs, executors and legal representatives
of Employee, upon Employee's death or Permanent Disability and (ii) any
successor of Employer.  As used in this Agreement, "successor" shall include any
person, firm, corporation or other business entity that at any time, whether by
purchase, merger, consolidation or otherwise, directly or indirectly acquires a
majority of the assets, business or stock of Employer.

          (d)  Integration.  This Agreement (together with any option agreement
               -----------
Employer may require Employee to execute in order to avail himself/herself of
any Stock Plan benefits specifically contemplated herein and any agreement to
release and hold harmless Employer executed concurrently herewith) constitutes
the entire agreement between the parties with respect to all matters covered
herein, including but not limited to the parties' employment relationship and
Employee's entitlement to compensation, commissions and benefits from Employer
or any of its affiliated companies and/or the termination of Employee's
employment.  This Agreement supersedes all prior oral or written understandings
and agreements relating to its subject matter and


all other business relationships between Employer and/or its affiliated
companies.

          (e)  No Representations.  No person or entity has made or has the
               ------------------
authority to make any representations or promises on behalf of any of the
parties which are inconsistent with the representations or promises contained in
this Agreement, and this Agreement has not been executed in reliance on any
representations or promises not set forth herein.  Specifically, no promises,
warranties or representations have been made by anyone on any topic or subject
matter related to Employee's relationship with Employer or any of its executives
or employees, including but not limited to any promises, warranties or
representations regarding future employment, compensation, commissions and
benefits, any entitlement to stock, stock rights, Stock Plan benefits, profits,
debt and equity interests in Employer or any of its affiliated companies or
regarding the termination of Employee's employment.  In this regard, Employee

made in the future unless they are set forth in writing and assigned by an
authorized representative of Employer.

               ----------
instrument executed by the parties that is designated as an amendment to this
Agreement.

          (g)  Counterparts.  This Agreement is being executed in one or more
               ------------
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

          (h)  Severability and Non-Waiver.  Any provision of this Agreement (or
               ---------------------------
portion thereof) which is deemed invalid, illegal or unenforceable in any
jurisdiction shall, as to that jurisdiction and subject to this Section, be
ineffective to the extent of such invalidity, illegality or unenforceability,
without affecting in any way the remaining provisions thereof in such
jurisdiction or rendering that or any other provisions of this Agreement
invalid, illegal, or unenforceable in any other jurisdiction.  If any covenant
should be deemed invalid, illegal or unenforceable because its scope is
considered excessive, such covenant shall be modified so that the scope of the
covenant is reduced only to the minimum extent necessary to render the modified
covenant valid, legal and enforceable.  No waiver of any provision or violation
of this Agreement by Employer shall be implied by Employer's forbearance or
failure to take action.

          (i)  Attorneys Fees.  In the event that any action or proceeding is
               --------------
commenced by


any party hereto for the purpose of enforcing any provision of this Agreement,
the parties to such action, proceeding or arbitration may receive as part of any
award, settlement, judgment, decision or other resolution of such action or
proceeding, whether or not reduced to a court judgment, their costs and
reasonable attorneys fees as determined by the person or body making such award,
settlement, judgment, decision or resolution.

          (j)  Voluntary and Knowledgeable Act. Employee represents and warrants

Agreement and has freely and voluntarily entered into this Agreement.

the date first above written.
