 to the merger will affect the market value of the merger consideration that ESSA shareholders may receive upon the closing of the merger.

| Q: | Will ESSA shareholders receive any fractional shares of CNB common stock as part of the merger 
 consideration?                                                                                 |

| A: | No. CNB will not issue any fractional shares of CNB common stock in the merger. Instead, CNB will pay ESSA                                                                                                                                              
 shareholders the cash value of a fractional share (without interest) in an amount determined by multiplying the fractional share interest to which such shareholder would otherwise be entitled by the average of the daily closing sales prices of one 
 share of CNB common stock as reported on NASDAQ for the five consecutive trading days ending on the third business day immediately prior to the closing date of the merger, rounded to the nearest whole cent.                                          |

| Q: | Is there a termination fee potentially payable under the merger agreement? |

| A: | Yes. Under certain circumstances, ESSA may be required to pay CNB a termination fee if the merger agreement is          
 terminated. See the section entitled “The Merger Agreement—Termination Fee” beginning on page 171 for more information. |

| Q: | Why are ESSA shareholders being asked to cast a non-binding advisory                                                       
 vote to approve the compensation that may become payable to ESSA’s named executive officers in connection with the merger? |

| A: | The SEC’s rules require ESSA to seek a non-binding advisory vote                                                                                  
 with respect to certain “golden parachute” compensation that may become payable to ESSA’s named executive officers in connection with the merger. |

| Q: | What will happen if ESSA shareholders do not approve the compensation that may become payable to ESSA’s 
 named executive officers in connection with the merger?                                                 |

| A: | The vote with respect to the “golden parachute” compensation is an advisory vote and will not be       
 binding on ESSA or CNB. Approval of the compensation that may become payable to ESSA’s named executive |

| officers is not a condition to completion of the merger. Therefore, if the ESSA merger proposal is approved by ESSA’s shareholders and the merger is subsequently completed, the compensation 
 (to the extent otherwise earned and payable) will still be paid to ESSA’s named executive officers, whether or not ESSA’s shareholders approve the compensation at the ESSA special meeting.  |
