I, Jennifer M. Champagne, certify that:

1. I have reviewed this annual report on Form 10-KSB of Cornerstone Bancorp;

2. 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;

3.  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 small business

4. The small business  issuer'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)) for the small business issuer 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  small  business  issuer,
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;

         c)  evaluated  the   effectiveness  of  the  small  business   issuer'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 small  business  issuer's
internal  control  over  financial  reporting  that  occurred  during  the small
business issuer's most recent fiscal quarter (the small business issuer's fourth
fiscal quarter in the case of an annual report) that has materially affected, or
is reasonably likely to materially  affect, the small business issuer's internal
control over financial reporting; and

5. The small business  issuer's other  certifying  officer and I have disclosed,
based  on  our  most  recent  evaluation  of  internal  control  over  financial
reporting,  to the small business  issuer's  auditors and the audit committee of
the small  business  issuer'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 small  business  issuer'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 small  business  issuer's
internal control over financial reporting.
