Accordingly, each Reporting Person reserves the right to change its intentions, as it deems appropriate. In particular, each Reporting Person may at any time and from time to time, in the open market, in privately negotiated transactions or otherwise, increase its holdings in the Company or dispose of all or a portion of the securities of the Company that the Reporting Persons now own or may hereafter acquire.
