Section 2. Dividends and Distributions. (A) Subject to the rights of the holders of any shares of any series of Preferred Stock of the Corporation (the "Preferred Stock") (or any similar stock) ranking prior and superior to the Series B Preferred Shares with respect to dividends, each holder of one one-thousandth of a share (a "Unit") of Series B Preferred Shares, in preference to the holders of Common Shares, par value $.01 per share of the Corporation (the "Common Shares") and of any other stock of the Corporation ranking junior to the Series B Preferred Shares, shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the purpose, dividends payable in cash in an amount per Unit (rounded to the nearest cent) equal to the per share amount of cash dividends declared on the Common Shares. In the event the Corporation shall at any time after December 30, 1997 (the "Rights Declaration Date"), (i) declare any dividend on outstanding Common Shares, payable in Common Shares, (ii) subdivide outstanding Common Shares, or (iii) combine outstanding Common Shares into a smaller number of shares, then in each such case the amount to which the holder of a Unit of Series B Preferred Shares was entitled immediately prior to such event pursuant to the preceding sentence shall be adjusted by multiplying such amount by a fraction, the numerator of which is the number of Common Shares outstanding immediately after such event and the denominator of which is the number of Common Shares, that were outstanding immediately prior to such event.

(B) Except as otherwise provided herein, in the Certificate of Incorporation or in any other Amendment creating a series of Preferred Stock or any similar stock, and except as otherwise required by law, the holders of Units of Series B Preferred Shares and the holders of Common Shares and any other capital stock of the Corporation having general voting rights shall vote together as one class on all matters submitted to a vote of shareholders of the Corporation.

(B) In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on outstanding Common Shares, payable in Common Shares, (ii) subdivide outstanding Common Shares, or (iii) combine outstanding Common Shares into a smaller number of shares, then in each such case the aggregate amount to which holders of Units of Series B Preferred Shares were entitled immediately prior to such event pursuant to clause (i)(b) of paragraph (A) of this Section 5 shall be adjusted by multiplying such amount by a fraction the numerator of which shall be the number of Common Shares that are outstanding immediately after such event and the denominator of which shall be the number of Common Shares that were outstanding immediately prior to such event. Section 6. Consolidation, Merger, Etc. In case the Corporation shall enter into any consolidation, merger, combination or other transaction in which the Common Shares are converted into, exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case Units of Series B Preferred Shares shall at the same time be similarly converted into, exchanged for or changed into an amount per Unit (subject to the provisions for adjustment hereinafter set forth) equal to the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each Common Share is converted, exchanged or converted. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on outstanding Common Shares payable in Common Shares, (ii) subdivide outstanding Common Shares, or (iii) combine outstanding Common Shares into a small number of shares, then in each such case the amount set forth in the immediately preceding sentence with respect to the exchange or conversion of Units of Series B Preferred Shares shall be adjusted by multiplying such amount by a fraction the numerator of which shall be the number of common Shares that are outstanding immediately after such event and the denominator of which shall be the number of Common Shares that were outstanding immediately prior to such event.
