Important and Timely Improvements

Dear CNB Corporation Shareholder:

In the  past  year,  CNB has been  busy  implementing  new  policies  and  other
improvements  - all designed to make the bank more  efficient,  competitive  and
successful:

     o    Lending policies have been modernized,  so that our bankers are better
          able to assess and take advantage of opportunities.

     o    The  salary  structure  for our  employees  has been  updated  to help
          attract and retain high-caliber personnel.

     o    We've improved  technology  throughout the company and added email and
          voicemail capabilities,  making it easier for employees to communicate
          with each other and, more importantly, with customers.

     o    And we've  created a Governance  Committee  and made other  changes to
          meet modern high  standards  regarding  accountability,  openness  and
          responsibility for public corporations.

CNB is on its way to becoming the hallmark of excellence for community  banking.
But without strong leadership,  that vision will never be realized.  Please vote
for the "Blue Ribbon Slate" of director  nominees and help keep CNB on the right
path forward.
