and Michael T. Strianese in their capacities as directors of the Company is
incorporated by reference from Schedule I to the Company's Information
Statement attached as Annex A to the Schedule 14D-9 filed by the Registrant on

         The following table sets forth, as of January 8, 1999, the number of
shares and percentage of the Common Stock owned by all persons known by the
Company to own beneficially more than 5% of the Common Stock.  Pursuant to L-M
Acquisition Corporation's tender offer for all the outstanding shares of Common
Stock, all shares of Common Stock held as of January 7, 1999 by the Company's
directors and executive officers named in the Summary Compensation Table
incorporated by reference into Item 11 above were sold to L-M Acquisition
Corporation and, therefore, none of the Company's directors nor any of the
named executive officers owned any shares of Common Stock as of January 8,
1999.  Similarly, all options to acquire Common Stock held by the Company's
directors or the named executive officers have been cancelled and converted

number of Shares previously subject to such cancelled options and (b) the
amount by which $5.00 exceeds the exercise price per share previously subject
to such cancelled option.  This information has been obtained in part from such
