 that all proposals to be voted on at the CNB annual meeting, except for the CNB auditor ratification proposal, and all proposals to be voted on at the ESSA special meeting will be “non-routine”matters, and, as such, broker non-votes,if any, will be counted as present and entitled to vote for purposes of determining a quorum at the CNB annual meeting but not at the ESSA special meeting. You should instruct your broker, bank or other nominee to vote your shares by following the instructions provided by the broker, bank or nominee with this joint proxy statement/prospectus. If you fail to instruct your broker, bank, trustee or other nominee on how to vote, your shares will not be voted on any of the proposals presented at the ESSA special meeting or the CNB annual meeting, except for the CNB auditor ratification proposal, and will not affect the outcome of such proposals. However, for CNB shareholders, your broker, bank, trustee or other nominee is entitled to vote on the CNB auditor ratification proposal without your instructions.

| Q: | Can I change my vote after I have submitted my proxy? |

| A: | Yes. There are three ways you can change your vote at any time after you have submitted your proxy and before your proxy is voted at your shareholder meeting: |

| • |     | you may deliver a written notice bearing a date later than the date of your proxy card at the address listed below, stating that you revoke your proxy; |

| • |     | you may submit a new signed proxy card bearing a later date (if you submitted your proxy by internet or by telephone, you can vote again by internet or telephone); or |

| • |     | you may attend your shareholder meeting and vote online during the meeting, although attendance at the shareholder meeting will not, by itself, revoke a proxy. |

You should send any notice of revocation to the appropriate company at:
