without cause pursuant to Section 7.a. (above), or if after the initial eighteen
(18) month term, the Corporation


                                       4


shall pay Kohavi a severance fee equal to the greater of (a) the full amount of

payable under this Agreement, without deduction except for tax withholding
amounts, through the end of the term; or (b) six (6) months of his then-current
salary without bonus, subject to tax withholding amounts. There shall be no
severance in the event that this Agreement is terminated for cause in accordance

directly related to any of the Corporation's significant businesses, Kohavi
shall promptly notify the Corporation's Chairman of the Board of such

other than the Corporation, or any affiliate of the Corporation, any such
opportunity unless, as to any particular opportunity, the Board of Directors of
the Corporation fails to take appropriate action within thirty (30) days.
Kohavi's duty to notify the Corporation and to refrain from appropriating all
such opportunities for thirty (30) days shall neither be limited by, nor shall

         b. FAILURE TO NOTIFY. In the event that Kohavi fails to notify the
Corporation of, or so appropriates, any such opportunity without the express
written consent of the Corporation, Kohavi shall be deemed to have violated the
provisions of this Section notwithstanding the following:

               i.   The capacity in which Kohavi shall have acquired such
                    opportunity; or

               ii.  The probable success in the Corporation's hands of such
                    opportunity.

provisions of this Agreement may be waived, altered, amended or repealed in
whole or in part only upon the written consent of both parties to this

shall the waiver by either party of a breach of any provision hereof be taken or
held to be a waiver of any subsequent breach of the same provision or any other
provision.
