 indirectly, of (i) 50% or more of the combined voting power of CNB’s then-outstanding securities or (ii) 25% or more, but less than 50%, of the combined voting power of CNB’s then-outstanding securities if the transaction giving rise to 
 such beneficial ownership is not approved by the CNB Board of Directors;                                                                                                                                                                     |

| • |     | individuals who constitute the CNB Board of Directors as of the Effective Date (and any new directors whose                                                                       
 election or nomination has been approved by a majority of such directors) cease for any reason to constitute a majority of the members of such board of directors then in office; |

| • |     | CNB is consolidated or merged with another entity, regardless of whether CNB is the surviving entity, and                                                                                                                                            
 excluding transactions in which the holders of securities that represented 100% of the combined voting power of the securities of CNB immediately prior to such transaction, own, directly or indirectly, at least a majority of the combined voting 
 power of the securities of the surviving entity (or parent thereof) immediately after such transaction;                                                                                                                                              |

| • |     | all or substantially all of the assets of CNB and its subsidiaries are, directly or indirectly, sold, leased, 
 transferred, or otherwise conveyed to another person; or                                                      |

| • |     | the liquidation, winding up, or dissolution of CNB. |
