Gentlemen:

          Re:  The Columbia Gas System, Inc.  
               File No. 70-8575

          I have acted as Counsel for The Columbia Gas System, Inc.
("Columbia"), a Delaware corporation and holding company registered under the
Public Utility Holding Company Act of 1935 (the "Act") in connection with the
Joint Application-Declaration on Form U-1 (File No. 70-8575), as amended by
Amendment Nos. 1 and 2 (hereinafter referred to together as the
"Application-Declaration"), relating to the loan by Columbia of $4.3 million,
evidenced by a note (the "Note"), to the Employees' Thrift Plan of Columbia Gas
System Trust (the "Thrift Plan Trust"), in order to alleviate the hardship on
plan participants, each of whom is an employee of one of sixteen wholly-owned
Columbia subsidiaries, incurred as a result of the seizure of Confederation
Life Insurance Company of Canada by Canadian and U.S.  governmental
authorities.

          The loan by Columbia to the Thrift Plan Trust, as more fully
described in the Application-Declaration, is hereinafter sometimes referred to
as the "Proposed Transaction."

          In connection with the foregoing, I have examined:

     (i)       the Application-Declaration,

     (ii)      the form of Promissory Note evidencing the loan;

     (iii)     copies of the Restated Certificate of Incorporation and Bylaws
               of Columbia;

     (iv)      the Order of the United States Bankruptcy Court for the
               District of Delaware (the "Bankruptcy Court"), dated March 8,
               1995, approving the Proposed Transaction;

     (v)       the Closing Agreement On Final Determination Covering Specific
               Matters between the United States Internal Revenue Service (the
               "Service") and Columbia, et al., providing that the Service
               will 
   3
               treat the Employees' Thrift Plan of Columbia as not
               failing to satisfy the requirements of section 401(a) of the
               Internal Revenue Code; 

     (vi)      the Exemption issued by the United States Department of Labor,
               dated June 21, 1995, allowing Columbia to undertake the
               Proposed Transaction;

     (vii)     the Order of the Commission approving the Proposed Transaction
               (HCAR No. 62274 April 17, 1995); and

     (viii)    such other documents, records and matters of law as I deemed
               necessary to enable me to render this opinion.

               Based upon the foregoing and relying thereon, I am of the
opinion, assuming that all taxes and government charges in connection with such
transaction have been paid, that:

               (a)       all state and federal laws applicable to the Proposed
                         Transaction have been complied with;

               (b)       Columbia received an order from the Bankruptcy Court
                         authorizing the loan to the Thrift Plan Trust;

               (c)       Columbia is a validly organized and duly existing
                         corporation in good standing under the laws of the
                         State of Delaware;

               (d)       the Note evidencing the loan to the Thrift Plan Trust
                         as part of the Proposed Transaction is a valid and
                         binding obligation of the Thrift Plan Trust in
                         accordance with the terms of such Note;

               (e)       the consummation of the Proposed Transaction does not
                         violate the legal rights of the holders of any
                         securities issued by Columbia or any associate
                         company thereof; and

               (f)       the Proposed Transaction was consummated in
                         accordance with the Application-Declaration.
   4
               I hereby consent to the filing of this opinion together with the
Certificate of the corporation filed pursuant to Rule 24.

                                               Very truly yours,


                                               /s/ Joyce Koria Hayes
