                  INTRODUCTION TO UNAUDITED PRO FORMA CONDENSED
                        CONSOLIDATED FINANCIAL STATEMENTS

         On July 21, 2004, CenterPoint Energy, Inc. (the Company or CenterPoint
Energy) and Texas Genco Holdings, Inc. (Texas Genco) entered into a definitive
transaction agreement pursuant to which Texas Genco has agreed to be acquired in
a multi-step transaction by GC Power Acquisition LLC (GC Power Acquisition), a
newly formed entity owned in equal parts by investment funds affiliated with The
Blackstone Group, Hellman & Friedman LLC, Kohlberg, Kravis Roberts & Co. L.P.
and Texas Pacific Group, for approximately $3.65 billion in cash.

         The Company intends to use the anticipated net after-tax proceeds it
will receive from the transaction of approximately $2.5 billion primarily to pay
down outstanding debt, including senior debt under its bank credit facility that
is secured in part by the Company's 81% ownership interest in Texas Genco, and
for other general corporate purposes, including additional pension
contributions.

         The following unaudited pro forma condensed consolidated balance sheet
has been prepared to reflect the effect of the sale of Texas Genco as described
above on the CenterPoint Energy financial statements as if the sale had occurred
on June 30, 2004. The following unaudited pro forma condensed consolidated
financial statements of income for each of the three years in the period ended
December 31, 2003 and the six months ended June 30, 2004 have been prepared to
reflect the transaction as of the beginning of the earliest period presented.

         The unaudited pro forma condensed consolidated financial statements do
not purport to present CenterPoint Energy's actual results of operations as if
the transaction described above had occurred at the beginning of each period, as
applicable, nor are they necessarily indicative of CenterPoint Energy's
financial position or results of operations that may be achieved in the future.

         The unaudited pro forma condensed consolidated financial statements
should be read in conjunction with CenterPoint Energy's consolidated financial
statements and related notes and "Management's Discussion and Analysis of
Financial Condition and Results of Operations" included in the Annual Report on

       Financial Accounting Standards No. 144, "Accounting for the Impairment or
       Disposal of Long-Lived Assets," CenterPoint Energy recorded an impairment
       loss of $253 million in connection with the sale transaction,
       representing the excess of the carrying amount of its investment in Texas
       Genco over the net proceeds to be received. The Company had previously
       recorded an impairment of its investment in Texas Genco of $399 million
       in connection with the distribution of 19% of Texas Genco's outstanding
       shares of common stock to its shareholders in January 2003.

(c)    In accordance  with Emerging  Issues Task Force Issue No. 87-24
       "Allocation of Interest to Discontinued Operations", the Company has
       reclassified interest to discontinued operations of Texas Genco based on
       net proceeds to be received from the sale of Texas Genco of $2.5 billion,
       and has applied the proceeds to the amount of debt assumed to be paid
       down in each respective period according to the terms of the respective
       credit facilities in effect for those periods. In periods where only the
       term loan was assumed to be repaid, the actual interest paid was
       reclassified. In periods where a portion of the revolver was assumed to
       be repaid, the percentage of that portion of the revolver to the total
       outstanding balance was calculated, and that percentage was applied to
       the actual interest paid in those periods. Interest expense of $58
       million, $198 million and $23 million was reclassified to discontinued
       operations of Texas Genco in 2002, 2003 and the six months ended June 30,
       2004, respectively. The Company intends to use the remainder of the
       proceeds for other general corporate purposes, including further pension
       contributions, and is currently evaluating its alternatives.

(d)    General corporate overhead previously allocated to Texas Genco from
       the Company, which will not be eliminated by the sale of Texas Genco,
       has been reflected as general corporate overhead of CenterPoint Energy
       in income from continuing operations. The amounts reclassified were
       $22 million, $27 million and $27 million for 2001, 2002 and 2003,
       respectively and $10 million for the six months ended June 30, 2004.
