Companies) has under contract  (including  unfulfilled  purchase orders), or any
letter of supply or other supplier  contract or arrangement  entered into by any

himself or another,  attempt to hire,  or assist in or facilitate in any way the
solicitation  of any  employee  of any of the  Companies  (or any  affiliate  or
subsidiary  of any of the  Companies),  or any  employee of any person,  firm or
other  entity,  the employees of which any of the Companies (or any affiliate or
subsidiary of any of the Companies) has agreed not to hire or endeavor to hire.

     (b) In the event that the Executive's  employment is terminated pursuant to

fullest extent, duration and geographic scope permitted by law and enforceable.

compensation  payable under this Agreement  shall be subject to withholding  for
income and other  applicable  taxes to the extent required by applicable law, as
determined by the Companies in their reasonable judgment.

16. Waivers and Amendments.  No act, delay, omission or course of dealing on the
part of any party  hereto in  exercising  any right,  power or remedy  hereunder
