business time and attention to assisting Michiel van Schaik with the transition
work of merging (operationally) Vitronics and Soltec. Such duties will be
commensurate with that normally associated with a senior executive officer. The
period of time for the transition work will be determined by Michiel van Schaik,
but in no event will it be more than 12 months. The conduct of private business
affairs (including outside directorships and part-time consulting arrangements)
and participation in charitable and professional organizations is allowed so
long as such activities do not interfere with your duties and responsibilities
at Vitronics/Soltec.

It is recognized that, upon completion of the transition period, you will be
free to devote your entire time and attention to other interests and pursuits
and your salary and benefits would continue for the remainder of the two-year
