              (a)   Limited Covenants Not to Compete or Interfere. Executive
recognizes that a substantial part of the value of a company such as the Company
or its subsidiaries resides in the expertise of its employees such as Executive

significantly influences, and that the value of the Company or its subsidiaries
will be significantly diminished if Executive attempts to compete or interfere
with the Company or its subsidiaries or interfere with its activities, or
solicit its customers in contravention of this Section 6. Accordingly, Executive

months thereafter if Executive's employment is terminated pursuant to Clause 4

Company or its affiliates during the term of his employment and thereafter.
Executive shall not, except as required by law or regulation or in the ordinary
course of performance of his duties as an employee of the Company, intentionally
disclose, or use during the term of his employment and thereafter any
Proprietary Information. By way of illustration but not limitation, Proprietary
Information includes customer, prospective customer and

                                                                               7

data, records, computer programs, manuals, processes or methods and intangible
rights which are either developed by Executive during the term of his employment
or to which Executive has access, which development or access was rendered
possible by virtue of Executive's employment, and which is not generally known
to and not readily ascertainable through proper means other than the Company, by
other firms in the business.

              Upon termination of employment, Executive shall promptly return to
the Company all materials and all copies of materials involving any Proprietary
Information in Executive's possession or control. Executive agrees to represent
to the Company that he has complied with the provisions of this Section 6 upon
termination of employment.

              Executive agrees to keep the terms of this Agreement confidential
and agrees not to intentionally disclose such information to any person other
than the Executive's immediate family and the Executive's attorney and other
professional advisors except where required by law or regulation.

              (c)   Memoranda, etc. Executive acknowledges and agrees that all
memoranda, notes, reports, records and other documents made or compiled by
Executive, or made available to Executive during the term of employment
concerning the business of the Company or any of its subsidiaries, shall be the
Company's property and shall be delivered to the Company upon the termination of
Executive's employment, hereunder. Following the expiration or termination of
Executive's employment hereunder, Executive agrees to cooperate with reasonable
advance notice and at mutually convenient times, for a period of five (5) years
with respect to legal matters and for a period of one (1) year with respect to
all other matters, with the Company and its subsidiaries with respect to matters
with which Executive was involved during the term of his employment. The
Executive will be reimbursed for reasonable expenses incurred by the Executive
if Company requires travel.

              (d)   Survival. The provisions of this Section 6 shall survive the
termination or expiration of this Agreement and Executive's term of employment.

              (e)   New or Prospective Employer Notification. Executive agrees
that, prior to the commencement of any new employment with a new employer during
the twelve (12) month period following the term of his employment, Executive
will notify the Company of the name and address for such new employer and will
furnish such new employer with a copy of Section 6 of this Agreement. Executive
agrees that the Company may advise any new or prospective employer of Executive
of the existence and terms of Section 6 of this Agreement and furnish such new
or prospective employer with a copy of Section 6 of this Agreement.

              7.    Assignment.
                    ----------

              (a)   This Agreement is personal to the Executive and shall not be
assignable by the Executive except in the event of the Executive's death in
which case his estate succeeds to the Executive's interests.

                                                                               8
