                            CENTERPOINT ENERGY, INC.

     SCHEDULE I -- NOTES TO CONDENSED FINANCIAL INFORMATION (PARENT COMPANY)

    (1) The condensed parent company financial statements and notes should be
read in conjunction with the consolidated financial statements and notes of
CenterPoint Energy, Inc. (CenterPoint Energy or the Company) appearing in the
Annual Report on Form 10-K. CenterPoint Energy, Inc. is a public utility holding
company that became the parent of Reliant Energy, Incorporated (Reliant Energy)
and its subsidiaries on August 31, 2002 as part of a corporate restructuring of
Reliant Energy (the Restructuring). CenterPoint Energy is a registered public
utility holding company under the 1935 Act. Prior to the Restructuring, Reliant
Energy was a public utility holding company that was exempt from registration
under the 1935 Act. After the Restructuring, an exemption was no longer
available for the corporate structure that the Texas Utility Commission required
CenterPoint Energy to adopt under the Texas electric restructuring law.
CenterPoint Energy did not conduct any activities other than those incident to
its formation until September 1, 2002. Accordingly, statements of operations and
cash flows would not provide meaningful information and have been omitted for
periods prior to September 1, 2002.

    (2) As a registered public utility holding company, the Company and its
subsidiaries except Texas Genco Holdings, Inc. (Texas Genco) are subject to a
comprehensive regulatory scheme imposed by the Securities and Exchange
Commission (SEC) in order to protect customers, investors and the public
interest. Although the SEC does not regulate rates and charges under the 1935
Act, it does regulate the structure, financing, lines of business and internal
transactions of public utility holding companies and their system companies. In
order to obtain financing, acquire additional public utility assets or stock, or
engage in other significant transactions, CenterPoint Energy is required to
obtain approval from the SEC under the 1935 Act.

    The Company received an order from the SEC under the 1935 Act on June 30,
2003 and supplemental orders thereafter relating to its financing activities and
those of its regulated subsidiaries, as well as other matters. The orders are
effective until June 30, 2005. As of December 31, 2004, the orders generally
permitted the Company and its regulated subsidiaries to issue securities to
refinance indebtedness outstanding at June 30, 2003, and authorized the Company
and its regulated subsidiaries to issue certain incremental external debt
securities and common and preferred stock through June 30, 2005, without prior
authorization from the SEC. Further, the SEC has reserved jurisdiction over the
issuance by the Company and its regulated subsidiaries of certain amounts of
incremental external debt securities, so that the Company is required to obtain
SEC approval prior to issuing those incremental amounts.

    The orders require that if the Company or any of its regulated subsidiaries
issues any security that is rated by a nationally recognized statistical rating
organization (NRSRO), the security to be issued must obtain an investment grade
rating from at least one NRSRO and, as a condition to such issuance, all
outstanding rated securities of the issuer and of the Company must be rated
investment grade by at least one NRSRO. The orders also contain certain
requirements for interest rates, maturities, issuance expenses and use of
proceeds. Under the orders, the Company's common equity as a percentage of total
capitalization must be at least 30%. The SEC has acknowledged that prior to the
monetization of Texas Genco and the securitization of the true-up components,
the Company's common equity as a percentage of total capitalization is expected
to remain less than 30%. In addition, after the securitization, the Company's
common equity as a percentage of total capitalization, including securitized
debt, is expected to be less than 30%, which the SEC has permitted for other
companies.

    Effective January 1, 2004, CenterPoint Energy established a service company
in order to comply with the 1935 Act. As a result, certain assets and
liabilities of the parent company were transferred to the service company,
primarily property, plant and equipment, pension and other postemployment
benefit assets and obligations and related deferred taxes. These transfers have
been excluded from the Statement of Cash Flows for the year ended December 31,
2004 as they represent non-cash transactions.

    (3) On September 30, 2002, the Company distributed to its shareholders 240
million shares of Reliant Energy, Inc. (formerly Reliant Resources, Inc.) (RRI)
common stock, which represented the Company's approximately 83% ownership
interest in RRI, by means of a tax-free spin-off in the form of a dividend.
Holders of CenterPoint Energy common stock on the record date received 0.788603
shares of RRI common stock for each share of CenterPoint

                                       5


Energy stock that they owned on the record date. The total value of the RRI
Distribution, after the impairment charge discussed below, was $847 million.

    As a result of the spin-off of Reliant Resources, the Company recorded a
non-cash loss on disposal of discontinued operations of $4.4 billion in 2002.
This loss represented the excess of the carrying value of the Company's net
investment in RRI over the market value of RRI's common stock.

    (4) The Company distributed approximately 19% of the 80 million outstanding
shares of common stock of Texas Genco to its shareholders on January 6, 2003. As
a result of the distribution of Texas Genco common stock, the Company recorded a
pre-tax impairment charge of $399 million, which was reflected as a regulatory
asset in the Consolidated Balance Sheet as of December 31, 2003. This impairment
charge represents the excess of the carrying value of the Company's net
investment in Texas Genco over the market value of Texas Genco's common stock.

    In July 2004, the Company announced its agreement to sell its majority owned
subsidiary, Texas Genco, to Texas Genco LLC (formerly known as GC Power
Acquisition LLC), an entity owned in equal parts by affiliates of The Blackstone
Group, Hellman & Friedman LLC, Kohlberg Kravis Roberts & Co. L.P. and Texas
Pacific Group. On December 15, 2004, Texas Genco completed the sale of its
fossil generation assets (coal, lignite and gas-fired plants) to Texas Genco LLC
for $2.813 billion in cash. Following the sale, Texas Genco distributed $2.231
billion in cash to the Company. Texas Genco's principal remaining asset is its
ownership interest in a nuclear generating facility. The final step of the
transaction, the merger of Texas Genco with a subsidiary of Texas Genco LLC in
exchange for an additional cash payment to the Company of $700 million, is
expected to close during the first half of 2005, following receipt of approval
from the Nuclear Regulatory Commission. The Company recorded an after tax loss
of $366 million in 2004 related to the sale of Texas Genco.

    (5) On December 15, 2004, the Company permanently reduced its three-year
credit facility to $750 million from $2.34 billion. The credit facility was
composed of a $1.425 billion revolving credit facility (London interbank offered
rate (LIBOR) plus 300 basis points), which has been permanently reduced to $750
million, and a $915 million term loan (LIBOR) plus 350 basis points), which was
repaid and retired on December 15, 2004. As a result of the term loan repayment
and the permanent reduction of the revolving credit facility, the Company
expensed $15 million of unamortized loan costs in the fourth quarter of 2004
that were associated with these facilities.

    In March 2005, the Company replaced its $750 million revolving credit
facility with a $1 billion five-year revolving credit facility. Borrowings may
be made under the facility at LIBOR plus 100 basis points based on current
credit ratings. An additional utilization fee of 12.5 basis points applies to
borrowings any time more than 50% of the facility is utilized. Changes in credit
ratings would lower or raise the increment to LIBOR depending on whether ratings
improved or were lowered.

    On May 19, 2003, the Company issued $575 million aggregate principal amount
of convertible senior notes due May 15, 2023 with an interest rate of 3.75%.
Holders may convert each of their notes into shares of CenterPoint Energy common
stock, initially at a conversion rate of 86.3558 shares of common stock per
$1,000 principal amount of notes at any time prior to maturity, under the
following circumstances: (1) if the last reported sale price of CenterPoint
Energy common stock for at least 20 trading days during the period of 30
consecutive trading days ending on the last trading day of the previous calendar
quarter is greater than or equal to 120% or, following May 15, 2008, 110% of the
conversion price per share of CenterPoint Energy common stock on such last
trading day, (2) if the notes have been called for redemption, (3) during any
period in which the credit ratings assigned to the notes by both Moody's
Investors Service, Inc. (Moody's) and Standard & Poor's Ratings Services (S&P),
a division of The McGraw-Hill Companies, are lower than Ba2 and BB,
respectively, or the notes are no longer rated by at least one of these ratings
services or their successors, or (4) upon the occurrence of specified corporate
transactions, including the distribution to all holders of CenterPoint Energy
common stock of certain rights entitling them to purchase shares of CenterPoint
Energy common stock at less than the last reported sale price of a share of
CenterPoint Energy common stock on the trading day prior to the declaration date
of the distribution or the distribution to all holders of CenterPoint Energy
common stock of the Company's assets, debt securities or certain rights to
purchase the Company's securities, which distribution has a per share value
exceeding 15% of the last reported sale price of a share of CenterPoint Energy
common stock on the trading day immediately preceding the declaration date for
such distribution. The convertible senior notes also have a contingent interest
feature requiring contingent interest to be paid to holders of notes commencing
on or after May 15, 2008, in the event that the average trading price of a note
for the applicable five trading day period equals or exceeds 120% of the
principal amount of the note as of the day immediately preceding the first day
of the applicable six-month interest period. For any

                                       6


six-month period, contingent interest will be equal to 0.25% of the average
trading price of the note for the applicable five-trading-day period.

    In March 2005, the Company filed a registration statement relating to an
offer to exchange its 3.75% convertible senior notes due 2023 for a new series
of 3.75% convertible senior notes due 2023. This registration statement has not
yet been declared effective by the SEC. The Company expects to conduct the
exchange offer in response to the guidance set forth in Emerging Issues Task
Force No. 04-8, "Accounting Issues Related to Certain Features of Contingently
Convertible Debt and the Effect on Diluted Earnings Per Share". Under that
guidance, because settlement of the principal portion of new notes will be made
in cash rather than stock, exchanging new notes for old notes will allow the
Company to exclude the portion of the conversion value of the new notes
attributable to their principal amount from its computation of diluted earnings
per share from continuing operations.

    On December 17, 2003, the Company issued $255 million aggregate principal
amount of convertible senior notes due January 15, 2024 with an interest rate of
2.875%. Holders may convert each of their notes into shares of CenterPoint
Energy common stock, initially at a conversion rate of 78.064 shares of common
stock per $1,000 principal amount of notes at any time prior to maturity, under
the following circumstances: (1) if the last reported sale price of CenterPoint
Energy common stock for at least 20 trading days during the period of 30
consecutive trading days ending on the last trading day of the previous calendar
quarter is greater than or equal to 120% of the conversion price per share of
CenterPoint Energy common stock on such last trading day, (2) if the notes have
been called for redemption, (3) during any period in which the credit ratings
assigned to the notes by both Moody's and S&P are lower than Ba2 and BB,
respectively, or the notes are no longer rated by at least one of these ratings
services or their successors, or (4) upon the occurrence of specified corporate
transactions, including the distribution to all holders of CenterPoint Energy
common stock of certain rights entitling them to purchase shares of CenterPoint
Energy common stock at less than the last reported sale price of a share of
CenterPoint Energy common stock on the trading day prior to the declaration date
of the distribution or the distribution to all holders of CenterPoint Energy
common stock of the Company's assets, debt securities or certain rights to
purchase the Company's securities, which distribution has a per share value
exceeding 15% of the last reported sale price of a share of CenterPoint Energy
common stock on the trading day immediately preceding the declaration date for
such distribution. Under the original terms of these convertible senior notes,
CenterPoint Energy could elect to satisfy part or all of its conversion
obligation by delivering cash in lieu of shares of CenterPoint Energy. On
December 13, 2004, the Company entered into a supplemental indenture with
respect to these convertible senior notes in order to eliminate its right to
settle the conversion of the notes solely in shares of its common stock. The
convertible senior notes also have a contingent interest feature requiring
contingent interest to be paid to holders of notes commencing on or after
January 15, 2007, in the event that the average trading price of a note for the
applicable five-trading-day period equals or exceeds 120% of the principal
amount of the note as of the day immediately preceding the first day of the
applicable six-month interest period. For any six-month period, contingent
interest will be equal to 0.25% of the average trading price of the note for the
applicable five-trading-day period.

    (6) On December 30, 2004, the Board of Directors of the Company adopted a
plan for an accounting reorganization of the Company, to be effective as of
January 1, 2005. This plan was adopted in order to eliminate the accumulated
retained earnings deficit that exists.

    The plan adopted by the Company required: (1) a report to be presented to
and reviewed by the Company's Board of Directors on or before February 28, 2005
as to the completion of the valuation analysis of the accounting reorganization
and the effects of the accounting reorganization on the Company's financial
statements, (2) a determination that the accounting reorganization is in
accordance with accounting principles generally accepted in the United States,
and (3) that there be no determination by the Company's Board of Directors on or
before February 28, 2005 that the accounting reorganization is inconsistent with
the Company's regulatory obligations. The Company is continuing to work to
complete the valuation analysis and the effects on the Company's financial
statements of the accounting reorganization, and on February 23, 2005, the
Company's Board of Directors extended until May 10, 2005 the time for making the
determination described in (3) of the preceding sentence.

    An accounting reorganization, sometimes called a "quasi-reorganization,"
allows a company to extinguish a negative retained earnings balance. It involves
restating a company's assets and its liabilities to their fair values. The
negative balance in the retained earnings account is then brought to zero
through a reduction in the other capital accounts, giving the company a "fresh
start" with a zero balance in retained earnings. As of December 31, 2004, the
Company had an accumulated retained earnings deficit of approximately $1.7
billion. That deficit stemmed from the

                                       7


accounting effects of (1) the Company's distribution of its ownership interest
in RRI to its shareholders in September 2002, (2) the extraordinary loss
recorded in connection with the Texas Utility Commission's order related to the
2004 True-Up Proceeding (defined below) and (3) the loss on discontinued
operations that was recorded in connection with the Company's sale of Texas
Genco. Those events stemmed from the Company's response to the Texas electric
restructuring law. In addition to eliminating the accumulated deficit in
retained earnings and restating assets and liabilities to fair value, if a
quasi-reorganization were implemented, the Company and CenterPoint Houston would
be required to implement any accounting standards that have been issued but not
yet adopted.

    The Company is seeking to eliminate the negative retained earnings balance
because restrictions contained in the 1935 Act require registered public utility
holding companies, like the Company, to obtain express authorization from the
SEC to pay dividends when current or retained earnings are insufficient to do
so. Eliminating the negative retained earnings balance will permit current
earnings not utilized to pay dividends to more quickly build up a retained
earnings balance. Under 1935 Act regulations, the Company could pay dividends
out of this balance during periods when current earnings may not be adequate to
do so.

    In addition, the Company has undertaken an obligation under the 1935 Act to
achieve a minimum ratio of common equity to total capitalization of thirty
percent, which, depending on the results of the restatement of assets and
liabilities under the accounting reorganization, could be affected by, and will
be taken into consideration by the Board of Directors in evaluating the effects
of, the accounting reorganization. The Company will seek such authority as may
be required under the 1935 Act in connection with the quasi-reorganization.
