        The foregoing computations do not reflect any significant potentially
dilutive effect Registrant's Preferred Stock Purchase Rights Plan could have in
the event such Rights become exercisable and any shares of either Series A
Preferred Stock or Common Stock of Registrant are issued upon the exercise of
such Rights. Reference is made to the Note 18, captioned "Preferred Stock
Purchase Rights Plan", in the Notes to Financial Statements set forth in Item 8
of the Registrant's Annual Report on Form 10-K for the year ended December 31,
1995, at page 49.
