             Re:  CSB Financial Group, Inc. -- Registration of 103,500
                  Shares of Common Stock, Par Value $0.01 Per Share, on
                  Form S-8
                  -----------------------------------------------------
   Gentlemen:

             We have acted as special counsel to CSB Financial Group,
   Inc., a Delaware corporation (the "Company"), in connection with the
   Company's filing of a Registration Statement on Form S-8 (the
   "Registration Statement") relating to the offer and sale by the
   Company of 103,500 shares of Common Stock of the Company, par value
   $0.01 per share (the "Shares"), pursuant to the CSB Financial Group,
   Inc. 1997 Nonqualified Stock Option Plan (the "Plan"), as more fully
   described in the Registration Statement.

             In this connection, we have examined such corporate records,
   certificates and other documents and have made such other factual and
   legal investigations as we have deemed necessary or appropriate for
   purposes of this opinion.

             Based upon the foregoing, we are of the opinion that the
   Shares have been duly authorized and, upon issuance and payment
   therefor in the manner and upon the terms contemplated in the
   Registration Statement and the Plan, will be legally issued, fully
   paid and nonassessable.

             We hereby consent to the filing of this opinion as an
   exhibit to the Registration Statement.

                                      Very truly yours,

                                      SCHIFF HARDIN & WAITE
