Meeting (the "Class A directors"); and William H. Thalheimer constitutes a
class with a term ending in 2000 (the "Class B directors"). At each annual
meeting of Stockholders, directors are elected for a full term of three years to
succeed those directors whose terms are expiring.

  Pursuant to a Stockholders Agreement entered into in December 1994, Messrs.
Najda and Bialek have each agreed to vote their shares in favor of the other's
election to the Board of Directors, and not vote their shares in favor of the
election to the Board of Directors of any person to which the other reasonably
objects.

  The names of the Company's current directors and certain information about
them are set forth below:

Stock Plan, in the event of a consolidation or acquisition of the Company, the
Compensation Committee may terminate all options in exchange for a cash payment
equal to the difference between the fair market value of the shares then subject
