by the Rights Certificate or Rights Certificates surrendered.  If this Rights 
Certificate shall be exercised in part, the registered holder shall be entitled 
to receive, upon surrender hereof, another Rights Certificate or Rights 
Certificates for the number of whole Rights not exercised.
            Subject to the provisions of the Rights Agreement, each Right 
evidenced by this Certificate may be (a) redeemed by the Company under certain 
circumstances, at its option, at a redemption price of $0.01 per Right or (b) 
exchanged by the Company under certain circumstances, at its option, for one 
share of Common Stock or one one-hundredth of a share of Preferred Stock per 
Right (or, in certain cases, other securities or assets of the Company), 
subject in each case to adjustment in certain events as provided in the Rights 
Agreement.
            No holder of this Rights Certificate, as such, shall be entitled to 
vote or receive dividends or be deemed for any purpose the holder of any 
securities which may at any time be issuable on the exercise hereof, nor shall 
anything contained in the Rights Agreement or herein be construed to confer 
upon the holder hereof, as such, any of the rights of a shareholder of the 
Company or any right to vote for the election of directors or upon any matter
