ESSA may terminate the merger agreement, subject to its compliance with the merger agreement, if ESSA has received an acquisition proposal, and the ESSA Board of Directors has made a determination that such proposal is a superior proposal and has determined to accept such proposal. See the section entitled “The Merger Agreement—Termination” beginning on page 170 for a further discussion of the circumstances under which the merger agreement could be terminated. The merger is subject to a number of conditions, including the receipt of waivers and/or approvals from governmental authorities, that may delay the merger or adversely impact CNB’s and ESSA’s ability to complete the merger.

CNB and ESSA cannot provide any assurances with respect to the timing of the closing of the merger, whether the merger will
