          NOW, THEREFORE, in consideration of the premises and

          1.   The last sentence of Section 2.3(c) of the Merger
Agreement is hereby amended and restated to read in its entirety
as follows:

          "Until surrendered as contemplated by this Section 2.3,
          each Certificate shall be deemed at any time after the
          Effective Time to represent (i) the right to receive
          upon such surrender the certificate representing
          Company Shares and cash in lieu of any fractional
          shares of Company Common Stock as contemplated by this
          Section 2.3 and (ii) all other rights attributable to
          the Company Shares including the payment of any
          dividend or other distribution declared or made with
          respect to Company Shares with a record date after the
          Effective Time."


          2.   Section 2.3(d) of the Merger Agreement is hereby
amended and restated to read in its entirety as follows:

          "Notwithstanding the last sentence of Section 2.3(c),
          at any time after the Effective Time the Board of
          Directors of the Company may decide that no dividends
          or other distributions declared or made with respect to
          Company Shares with a record date after the time of
          said decision (the "Decision Time") shall be paid to
          the holder of any unsurrendered Certificate with
          respect to the Company Shares represented thereby.  In
          such event, and subject to the effect of unclaimed
          property, escheat and other applicable laws, following
          surrender of any such Certificate, there shall be paid
          to the record holder of the certificates representing
          whole Company Shares issued in exchange therefor,
          without interest, (i) at the time of such surrender,
          the amount of dividends or other distributions with a
          record date after the Decision Time theretofore paid
          with respect to such whole Company Shares and (ii) at
          the appropriate payment date, the amount of dividends
          or other distributions with a record date after the
          Decision Time but prior to surrender and a payment date
          subsequent to surrender payable with respect to such
          whole Company Shares, as the case may be."

          3.  The last sentence of Section 6.1(b) of the Merger
Agreement is hereby amended and restated to read in its entirety
as follows:

          "Notwithstanding the foregoing, (i) Energy may redeem
          all or any portion of its (x) Energy Preferred Stock,
          3.50% Series, of which 42,017 shares are outstanding,
          (y) Energy Preferred Stock, 8.52% Series, of which
          211,190 shares are outstanding and (z) Energy Preferred
          Stock, 8.96% Series, of which 216,900 shares are
          outstanding and (ii) CG&E's redemption of 400,000
          shares of its CG&E Preferred Stock, 9.28% Series, is
          permitted."

          4.  The first sentence of Section 6.1(c) is hereby
amended to change the number 3,700,000 in clause (ii)(x) to
5,000,000.


          5.   Clause (ii) of section 6.1(h) of the Merger
Agreement is hereby amended and restated to read in its entirety
as follows:

          "(ii) long-term indebtedness not aggregating
          more than (x) in the case of PSI and its
          subsidiaries, $550 million and (y) in the
          case of CG&E and its subsidiaries, $300
          million, in each case other than in
          connection with the refunding of outstanding
          long-term indebtedness which refunding is at
          a lower interest rate than that of the
          original indebtedness;"

          6.   Without limiting in any respect any of the
representations and warranties set forth in the Merger Agreement,
each party represents and warrants with respect to itself that
this Amendment has been duly and validly authorized, executed and
delivered and constitutes a valid and binding obligation of each
such party enforceable against such party in accordance with its
terms.

          7.   The Merger Agreement is hereby reaffirmed in its
entirety, except to the extent specifically amended hereby.

          8.   This Amendment may be executed in any number of
counterparts and by the different parties hereto on separate
counterparts, each of which counterparts when executed and
delivered shall be an original, but all of which shall together
constitute one and the same instrument.

          9.   THIS AMENDMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT
REFERENCE TO THE PRINCIPLES OF CONFLICTS OF LAWS THEREOF.


          IN WITNESS WHEREOF, CG&E, PSI, Energy, CINergy Sub and
the Company have caused this Amendment to be signed by their
respective officers thereunto duly authorized as of the date
first written above.
