Re:      Form S-8 Registration Statement
         Community Bank & Trust Co. New Stock Option Plan

Ladies and Gentlemen:

         We have acted as counsel for Carolina First BancShares, Inc., a North
Carolina corporation (the "Corporation"), in connection with the referenced
Registration Statement on Form S-8 (the "Registration Statement") being filed
by the Corporation with the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended, and covering 39,995
shares of the Corporation's Common Stock, $2.50 par value ("Common Stock"),
that may be issued pursuant to the Community Bank & Trust Co. New Stock Option
Plan (the "Plan").

         In the capacity described above, we have considered such matters of
law and of fact, including the examination of originals or copies, certified or
otherwise identified to our satisfaction, of such records and documents of the
Corporation, certificates of public officials and such other documents as we
have deemed appropriate as a basis for the opinions hereinafter set forth.

         Based upon the foregoing, it is our opinion that the 39,995 shares of
Common Stock covered by the Registration Statement and to be issued pursuant to
the Plan, when issued in accordance with the terms and conditions of the Plan,
will be legally and validly issued, fully paid and nonassessable.

         This opinion is provided to you for your benefit and for the benefit
of the Commission, in each case, solely with regard to the Registration
Statement, may be relied upon by you and the Commission only in connection with
the Registration Statement, and may not be relied upon by any other person or
for any other purpose without our prior written consent.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and further consent to the use of our name wherever
appearing in the Registration Statement.

                                   Sincerely,

                                   ALSTON & BIRD LLP
