     Re:  Registration Statement on Form S-1

Ladies and Gentlemen:

     In connection with the registration under the Securities Act of 1933, as
amended (the "Act"), of up to $11,500,000 aggregate principal amount of Junior
Subordinated Deferrable Interest Debentures (the "Junior Subordinated
Debentures") of CB&T Holding Corporation, a Louisiana corporation (the
"Corporation"), up to $11,500,000 aggregate liquidation amount of Cumulative
Trust Preferred Securities (the "Trust Preferred Securities") of Crescent
Capital Trust I, a business trust created under the laws of the State of
Delaware (the "Issuer"), and the Guarantee with respect to the Trust Preferred
Securities (the "Guarantee") to be executed and delivered by the Corporation for
the benefit of the holders from time to time of the Trust Preferred Securities,
we, as your counsel, have examined such corporate records, certificates and
other documents, and such questions of law, as we have considered necessary or
appropriate for the purposes of this opinion.


Board of Directors
September 3, 1999

     Upon the basis of such examination, we advise you that, when:

      (1) the Registration Statement relating to the Junior Subordinated
    Debentures, the Trust Preferred Securities and the Guarantee has become
    effective under the Act;

      (2) the Guarantee Agreement relating to the Guarantee with respect to the
    Trust Preferred Securities of the Issuer has been duly executed and
    delivered;

      (3) the Junior Subordinated Debentures have been duly executed and
    authenticated in accordance with the Indenture and issued and delivered as
    contemplated in the Registration Statement; and

      (4) the Trust Preferred Securities have been duly executed in accordance
    with the Amended and Restated Trust Agreement of the Issuer and issued and
    delivered as contemplated in the Registration Statement;

the Junior Subordinated Debentures and the Guarantee relating to the Trust
Preferred Securities of the Issuer will constitute valid and legally binding
obligations of the Corporation, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors' rights and to general equity principles.

     We understand that you have received an opinion regarding the Trust
Preferred Securities from Richards, Layton & Finger, P.A., special Delaware
counsel for the Corporation and the Issuer.  We are expressing no opinion with
respect to the matters contained in such opinion.

     Also, we have relied as to certain matters on information obtained from
public officials, officers of the Corporation and other sources believed by us
to be responsible.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the references to us under the heading "Validity
of Securities" in the Prospectus.  In giving such consent, we do not thereby
admit that we are in the category of persons whose consent is required under
Section 7 of the Act.

                                      Very truly yours,

                                      ELIAS, MATZ, TIERNAN & HERRICK L.L.P


                                      By:   /s/ Gerald F. Heupel, Jr.
