         unreasonably withheld.

                  (c) The directors to be named by EVI have been identified in
         writing to the Company. If, prior to the Effective Time of the Merger,
         any of EVI's designees to the Board of Directors of the Surviving
         Corporation shall decline or be unable to serve as a director of the

                  (d) The directors to be named by the Company shall be from the
         existing directors of the Company and shall be required to be approved
         by EVI. The directors of the Surviving Corporation shall hold office in
         accordance with the Certificate of Incorporation and By-laws of the
         Surviving Corporation from the Effective Time of the Merger until the
         earlier of their resignation or removal or until their respective
         successors are duly elected and qualified, as the case may be.

                  (e) Subject to the fiduciary duties of the Board of Directors
         of the Surviving Corporation, and the willingness of such persons to
         serve as directors of the Surviving Corporation, the Board of Directors
         of the Surviving Corporation shall submit as nominees for election to

other terms and provisions of the Agreement shall remain in full force and
effect.

which shall for all purposes be deemed to be an original and all of which shall
constitute the same instrument.

with, the laws of the State of Delaware, regardless of the laws that might
otherwise govern under applicable principles of conflicts of laws thereof.
