Reaching Our Potential

Despite the dramatic economic  vitality in the coastal region it serves,  Conway
National  Bank has lagged  behind its  competitors  in terms of key  performance
indicators.

CNB was founded in 1903 and its competitor,  Coastal Federal Bank, was organized
in 1957. As recently as 1990, CNB's net income exceeded that of Coastal Federal.
But by 1997,  Coastal Federal began  outperforming  CNB and  essentially  earned
double our net income in 2005.*

According to the Carson Medlin Company's  Independent Bank Index, which compares
25 independent  banks in the Southeastern US, a hypothetical  $100 investment in
CNB in 2000 would have been worth $111 in 2001 and $199 in 2005.  That same $100
investment in an average community bank in the index would have grown to $124 in
2001 and $252 in 2005.

Clearly,  we can and should be doing better.  But we need leadership with strong
business  credentials  to realize our vision.  Please vote for the "Blue  Ribbon
Slate" of director nominees and help keep CNB on the right path forward.

Dear Fellow Shareholders:

I am not supporting the Willis and Jennings Duncan's slate of candidates for CNB
Corporation  directors  even though they list my name on their proxy.  I want to
explain why.

Until last year,  Conway  National Bank was being run like a small  family-owned
business.  Our lending policies were obsolete,  our technology was embarrassing,
our pay and employee  benefits were below market,  and our management  style was
patriarchal.  We  were  losing  market  share  to  traditional  competitors  and
start-ups.

Conway  National  has an  opportunity  to  become  one of the best  banks in the
southeast.  We have good, loyal and experienced employees,  we have a remarkably
valuable  base of customers and business  associates,  and we are blessed with a
very healthy local economy.

This is not personal. This is business. The future of CNB will be decided on May
9, 2006.  Do we go back to  restrictive  loan  policies,  delayed  technologies,
restrained  employee benefits and closed family control of our company? Or do we
develop our company as a modern bank that grows with our vibrant community?

Please return the enclosed BLUE proxy form to elect CNB  Corporation's  nominees
for directors: Paul Dusenbury,  George Goldfinch,  Russell Holliday and me. This
slate represents  experienced,  independent business people with high integrity.
If you have sent a green proxy  form,  please send in the later dated BLUE form.
My direct phone number is 843-488-8233.  I will be pleased to receive  questions
or comments from you.

Sincerely,


William R. Benson
Senior Vice President and Director
