Exhibit 31.2

                                 Certifications

I, Paul R.  Dusenbury,  Executive  Vice President and Chief  Financial  Officer,
certify that:

I have reviewed this quarterly report on Form 10-Q of CNB Corporation;

Based on my  knowledge,  this report does not contain any untrue  statement of a
material fact or omit to state a material fact  necessary to make the statements
made, in light of the  circumstances  under which such statements were made, not
misleading with respect to the period covered by this report;

Based on my knowledge, the financial statements, and other financial information
included in this report,  fairly present in all material  respects the financial
condition,  results of  operations  and cash flows of the  registrant as of, and
for, the periods presented in this report;

The registrant's other certifying officer and I are responsible for establishing
and maintaining  disclosure  controls and procedures (as defined in Exchange Act
Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as
defined in Exchange Act Rules  13a-15(f) and  15d-15(f))  for the registrant and
have:

(a)      Designed  such  disclosure  controls  and  procedures,  or caused  such
         disclosure   controls  and   procedures   to  be  designed   under  our
         supervision,  to  ensure  that  material  information  relating  to the
         registrant,  including its consolidated subsidiaries, is made known, to
         us by others within those entities,  particularly  during the period in
         which this report is being prepared;

(b)      Designed such internal control over financial reporting, or caused such
         internal  control over  financial  reporting  to be designed  under our
         supervision,  to provide reasonable assurance regarding the reliability
         of financial reporting and the preparation of financial  statements for
         external  purposes in accordance  with  generally  accepted  accounting
         principles;

(c)      Evaluated the effectiveness of the registrant's disclosure controls and
         procedures  and  presented  in this  report our  conclusions  about the
         effectiveness of the disclosure controls and procedures,  as of the end
         of the period covered by this report based on such evaluation; and

(d)      Disclosed  in this  report  any  change  in the  registrant's  internal
         control over financial  reporting that occurred during the registrant's
         most recent fiscal quarter (the  registrant's  fourth fiscal quarter in
         the case of an  annual  report)  that has  materially  affected,  or is
         reasonably  likely to  materially  affect,  the  registrant's  internal
         control over financial reporting; and

The  registrant's  other certifying  officer and I have disclosed,  based on our
most recent  evaluation of internal  control over  financial  reporting,  to the
registrant's  auditors  and the audit  committee  of the  registrant's  board of
directors (or persons performing the equivalent functions):

(a)      All significant  deficiencies and material  weaknesses in the design or
         operation  of  internal  control  over  financial  reporting  which are
         reasonably  likely to  adversely  affect  the  registrant's  ability to
         record, process, summarize and report financial information; and

(b)      Any fraud,  whether or not material,  that involves management or other
         employees  who have a  significant  role in the  registrant's  internal
         control over financial reporting.
