agree that the court making the determination of invalidity or
unenforceability shall have the power to reduce the scope, duration or area
of the term or provision, to delete specific words or phrases, or to
replace any invalid or unenforceable term or provision with a term or
provision that is valid and enforceable and that comes closest to
expressing the intention of the invalid or unenforceable term or provision,
and this Agreement shall be enforceable as so modified.

	9.	Confidential Information.

		a.	March agrees that during and after the Term he will not,
directly or indirectly, disclose to any person, or use or otherwise

Information if and to the extent disclosure thereof is specifically required

appropriate protective order.

		b.	At the request of the Company, March agrees to deliver to
the Company, at any time during the Term, or thereafter, all Confidential
Information which March may possess or control.  March agrees that all
Confidential Information of the Company (whether now or hereafter existing)

or which hereinafter may be sold, developed or contemplated, by the Company

(the "Products") or other proprietary or intellectual property of the Company,
whether or not in written or tangible form, and whether or not registered,
and including all memoranda, notes, summaries, plans, reports, records,
documents and other evidence thereof.  The term "Confidential Information"
does not include, and there shall be no obligation hereunder with respect to,
information that becomes generally available to the public other than as a
result of a disclosure by March not permissible hereunder.

	10.	Key Man Insurance.  March agrees to cooperate with the Company
obtaining and maintaining during the Term at its expense a term insurance
