                  Exchange Act.

     All documents  filed by the Company or the Plan pursuant to Sections 13(a),
13(c),  14 and 15(d) of the  Exchange  Act  after the date of this  registration
statement, and prior to the filing of a post-effective amendment which indicates
that all securities  offered have been sold or which  deregisters all securities
then remaining  unsold,  shall be deemed to be incorporated by reference in this
registration  statement  and to be part  thereof from the date of filing of such
documents.

Item 4.  Description of Securities.

     The Common Stock is registered under Section 12 of the Exchange Act.

Item 5.  Interests of Named Experts and Counsel.

     None

Item 6.  Indemnification of Directors and Officers.

     Section 6.01 of the Company's By-Laws  provides,  in part, that the Company

officers and  directors in connection  with any actual,  threatened or completed
action,  suit or  proceeding  arising out of their  service to the Company or to
another entity at the request of the Company.

     The  Company's  directors  and officers  currently  are covered as insureds

Item 8. Exhibits.

     The  following  exhibit  is  filed  herewith  as part of this  registration
statement:

                  23.3     Consent of Independent Accounting Firm.

     The  Company  has  submitted  the Plan and all  amendments  thereto  to the
Internal  Revenue  Service  ("IRS") in a timely  manner and has made all changes
required by the IRS in order to qualify the Plan.

Item 9. Undertakings.

     The undersigned registrant undertakes 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 section  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.  The  registrant
further  undertakes  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 offering.  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 indemnification provisions
described in Item 6, 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.

     The  following  exhibit  is  filed  herewith  as part of this  registration
statement:

                  23.3     Consent of Independent Accounting Firm.

     The  Company  has  submitted  the Plan and all  amendments  thereto  to the
Internal  Revenue  Service  ("IRS") in a timely  manner and has made all changes
required by the IRS in order to qualify the Plan.

Item 9. Undertakings.

     The undersigned registrant undertakes 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 section  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.  The  registrant
further  undertakes  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 offering.  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 indemnification provisions
described in Item 6, 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.
