fiduciary capacity for the benefit of the Company and its affiliates and shall
not directly or indirectly use or disclose any Trade Secret that Executive may

generally known to, and not being generally readily ascertainable by proper
means by, other persons who can obtain economic value from its disclosure or use
and (2) is the subject of reasonable efforts by the Company and any of its
affiliates to maintain its secrecy. This Section is intended to provide rights
to the Company and its subsidiaries or affiliates that are in addition to, not
in lieu of, those

                                        5

<PAGE>

rights the Company and its affiliates have under the common law or applicable

during his employment disclose to any third parties, other than in carrying out
his duties hereunder, Confidential Information, and he shall confine use of
Confidential Information exclusively to carrying out his employment

Executive shall, immediately upon termination of employment, return to the
Company all Confidential Information, as well as any copies of that information
and any other material, including handwritten notes, made or derived from that
information.

            9. NON-COMPETITION. Executive shall not in the continental United
States for a period of two years following termination of employment engage,
either directly or indirectly, as an Executive, officer, director, shareholder,
partner or in any other capacity in a business which is competitive with the
business of the Company. Notwithstanding the preceding sentence, Executive will
not be prohibited from owning less than five (5%) percent of any publicly traded
corporation regardless of the business, in which such corporation is engaged.
If, at the time of enforcement of this provision, a court of competent
jurisdiction holds that the restrictions stated herein are unreasonable under
the circumstances then existing, the parties agree that the maximum period or
scope under the circumstances shall be substituted for the period or scope
stated herein.

            10. NON-SOLICITATION OF CUSTOMERS OR EMPLOYEES. Executive agrees
that, during the term of this Agreement and for a period of two years
thereafter, he will not knowingly, directly for himself or for any other person
or entity, divert, call on, solicit, or take away or attempt to divert, call on,
solicit or take away present or actively solicited prospective employees or,
with respect to competitive products or services, any present or actively
solicited prospective suppliers or customers of the Company or any of its
subsidiaries or affiliates.

            11. REASONABLENESS OF RESTRAINTS; IRREPARABLE HARM; BREACH OF
                AGREEMENT: NO DEFENSE.

trade secrets and other business interests of the Company and that they will
cause Executive no undue hardship.

cause the Company immediate irreparable harm for which injunctive relief would
be necessary. The non- prevailing party shall pay all reasonable expenses and
costs, including attorneys' fees, incurred by the other prevailing party hereto,
in any proceeding to enforce the covenants or any other provisions of this
Agreement.

            (c) Executive acknowledges that the covenants of paragraphs 10
through 12 of this Agreement are of the essence of this Agreement. They shall be
construed as independent of any other provision in this Agreement, and the
existence of any claim or cause of action of Executive against the Company,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by the Company of these covenants.
