 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:

If you hold your shares of ESSA common stock or CNB common stock in “street name” through a bank, broker, trustee or other nominee, you must follow the directions you receive from your bank, broker, trustee or other nominee to change your voting instructions.

| Q: | What if I hold stock of both CNB and ESSA? |

| A: | If you hold shares of both CNB and ESSA, you will receive two separate packages of proxy materials. A vote as an ESSA shareholder for any proposals to be considered at the ESSA special meeting will not constitute a vote as a CNB shareholder for any proposals to be considered at the CNB annual meeting, and vice versa. Therefore, please sign, date and return all proxy cards that you receive, whether from CNB or ESSA, or vote via the internet or by telephone. |

| Q: | What happens if I sell my shares of ESSA common stock after the record date but before the ESSA special meeting? |

| A: | If you sell or otherwise transfer your shares of ESSA common stock after the record date, but before the date of the ESSA special meeting, you will retain your right to vote at the ESSA special meeting, but you
