ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

  Directors and officers of the Company are indemnified and held harmless
against liability to the fullest extent permissible by the general corporation
law of Delaware as it currently exists or as it may be amended, provided any
such amendment provides broader indemnification provisions than currently
exists.  This indemnification applies to the directors who administer the 1993
Incentive Plan and 1993 Stock Option Plan.

  The terms of the indemnification are set forth in the Company's Certificate of
Incorporation.  The indemnification applies unless the director did not meet the
standards of conduct which make it permissible under the general corporation law
of Delaware for the Company to indemnify the director for the amount claimed,
but the burden of proving such defense is on the Company.

  The Company is also permitted under the Certificate of Incorporation to
maintain directors' and officers' liability insurance covering its directors and
officers and has obtained a directors' and officers' liability and corporation
reimbursement policy which (subject to certain limitations and deductibles) (i)
insures officers and directors of the Company against loss arising from certain
claims made against them by reason of their being such directors or officers;
and (ii) insures the Company against loss which it may be required or permitted
to pay as indemnification to its directors and officers for certain claims.

  Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers or persons controlling the Company,
the Company has been informed that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act of
1933 and is therefore unenforceable.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

  Not applicable.

ITEM 8.  LIST OF EXHIBITS.

  The following exhibits are filed with or incorporated by reference into this
Registration Statement on Form S-8:

     4.1  KSB Bancorp, Inc. 1993 Incentive Stock Option Plan (Incorporated by

ITEM 9.  UNDERTAKINGS

     The undersigned Registrant hereby undertakes:

     1.   To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement to include any material
information with respect to the Registration Statement not previously disclosed
in this Registration Statement or any material change to such information in
this Registration Statement;

     2.   That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof;

     3.   To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
1993 Incentive Stock Option Plan or 1993 Stock Option Plan for Outside
Directors; and

     4.   That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the Registrant's annual report pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by
reference in the Registration Statement shall be deemed to be a new Registration
Statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

     5.   Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

any other subsequently filed document which also is incorporated by reference
herein, modifies or supersedes such statement. Any such statement so modified or
superseded shall not be deemed, except as so modified or superseded, to

  The following documents filed or to be filed with the Commission are

  (a) The Company's Annual Report on Form 10-KSB for the year ended December 31,

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

  Directors and officers of the Company are indemnified and held harmless
against liability to the fullest extent permissible by the general corporation
law of Delaware as it currently exists or as it may be amended, provided any
such amendment provides broader indemnification provisions than currently
exists.  This indemnification applies to the directors who administer the 1993
Incentive Plan and 1993 Stock Option Plan.

  The terms of the indemnification are set forth in the Company's Certificate of
Incorporation.  The indemnification applies unless the director did not meet the
standards of conduct which make it permissible under the general corporation law
of Delaware for the Company to indemnify the director for the amount claimed,
but the burden of proving such defense is on the Company.

  The Company is also permitted under the Certificate of Incorporation to
maintain directors' and officers' liability insurance covering its directors and
officers and has obtained a directors' and officers' liability and corporation
reimbursement policy which (subject to certain limitations and deductibles) (i)
insures officers and directors of the Company against loss arising from certain
claims made against them by reason of their being such directors or officers;
and (ii) insures the Company against loss which it may be required or permitted
to pay as indemnification to its directors and officers for certain claims.

  Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers or persons controlling the Company,
the Company has been informed that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act of
1933 and is therefore unenforceable.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

  Not applicable.

ITEM 9.  UNDERTAKINGS

     The undersigned Registrant hereby undertakes:

     1.   To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement to include any material
information with respect to the Registration Statement not previously disclosed
in this Registration Statement or any material change to such information in
this Registration Statement;

     2.   That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof;

     3.   To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
1993 Incentive Stock Option Plan or 1993 Stock Option Plan for Outside
Directors; and

     4.   That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the Registrant's annual report pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by
reference in the Registration Statement shall be deemed to be a new Registration
Statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

     5.   Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
