        Re:  NiSource Inc. - Registration Statement on Form S-3
             --------------------------------------------------

   Ladies and Gentlemen:

        We have acted as counsel to NiSource Inc., formerly NIPSCO
   Industries, Inc. an Indiana corporation (the "Corporation"), in
   connection with the Corporation's filing of a Registration
   Statement on Form S-3 (the "Registration Statement") relating to
   the offer and sale by the Corporation of 273,000 of its common
   shares, without par value (including associated preferred share 
   purchase rights) (the "Common Shares"), as more fully described in 
   the Registration Statement, through the Bay State Gas Company 
   Employee Savings Plan (the "Plan").

        In this connection, we have examined such documents and have made
   such 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:  (i) the
   written provisions of the current Plan documents comply with the
   applicable provisions of the Employee Retirement Income Security Act
   of 1974; and (ii) the Common Shares have been duly authorized and,
   when issued upon payment therefor, as contemplated in the
   Registration Statement, 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
