“(x) the Rights will be evidenced (subject to the provisions of paragraph (b) of this Section 3) by the shares of Company Common Stock, whether represented by certificates or uncertificated, registered in the names of the holders of shares of Company Common Stock as of and subsequent to the Record Date (which shares of Company Common Stock shall be deemed also to represent the Rights) and not by separate certificates”

Section 3(b) of the Rights Agreement shall be amended in its entirety to read as follows:

“(b) As promptly as reasonably practicable following the Record Date, the Company will send a copy of a Summary of Rights to Acquire Company Common Stock in a form which may be appended to certificates that represent shares of Company Common Stock which may be written statements describing shares of Company Common Stock, in substantially the form attached hereto as Exhibit B (the “Summary of Rights”), by first-class, postage prepaid mail, to each record holder of shares of Company Common Stock as of the Close of Business on the Record Date, at the address of such holder shown on the records of the Company.”

With respect to shares of Company Common Stock (whether represented by certificates or uncertificated, and whether or not such certificates representing them or such written statements describing them include the foregoing legend/notice or have appended to them the Summary of Rights), until the earlier of the Distribution Date and the Expiration Date, the Rights associated with the shares of Company Common Stock shall be evidenced by shares alone and registered holders of the shares of Company Common Stock shall also be the registered holders of the associated Rights, and the transfer of any of such shares shall also constitute the transfer of the Rights associated with the shares of Company Common Stock.”
