                                    The Trust
 
 . REI Trust I is a subsidiary of Houston Industries Incorporated (hereinafter
   referred to as "Reliant Energy" or the "Company") and a statutory business
   trust created under Delaware law.
                                  The Offering
 
 . In connection with this offering, the Trust will:
  . sell Preferred Securities to the public and Common Securities to Reliant
    Energy;
  . use the proceeds from these sales to buy an equivalent principal amount of
     % Junior Subordinated Debentures due 2048 issued by Reliant Energy; and
  . distribute the cash payments it receives on the Junior Subordinated
    Debentures to the holders of the Preferred and Common Securities.
                            The Preferred Securities
 
 . The Preferred Securities represent undivided preferred beneficial interests
   in the assets of the Trust.
 
 . If you purchase Preferred Securities, you will be entitled to receive
   cumulative cash distributions at an annual rate of   % of the $25

   Junior Subordinated Debentures for up to 20 consecutive quarterly periods.
   If Reliant Energy defers interest payments, the Trust will also defer
   payment of distributions on the Preferred and Common Securities. During a
   deferral period, distributions will continue to accumulate on the Preferred
   and Common Securities. Also, additional cash distributions will accumulate
   on any deferred distributions at an annual rate of   %, to the extent
   permitted by law.

   The following information supplements, and should be read together with, the
information contained in other parts of this prospectus supplement and in the
accompanying prospectus. This summary highlights selected information included
elsewhere in this prospectus supplement and the accompanying prospectus to help
you understand the terms of the Preferred Securities. You should carefully read

                                   The Trust
 
   REI Trust I is a subsidiary of Reliant Energy and a statutory business trust
recently created under Delaware law. In connection with this offering, the
Trust will sell its Preferred Securities to the public and its Common
Securities to Reliant Energy. The Trust will use the proceeds from these sales
to buy an equivalent principal amount of     % Junior Subordinated Debentures
due 2048 issued by Reliant Energy. The Preferred Securities and the Junior
Subordinated Debentures will have essentially the same terms.
 
                                 Reliant Energy
 
   Reliant Energy is a diversified international energy services company that
previously conducted business under the name "Houston Industries Incorporated."
Its executive offices are located at 1111 Louisiana, Houston, Texas 77002
(telephone number: (713) 207-3000).
 
   In connection with this offering, Reliant Energy will acquire all of the
Trust's Common Securities. The Common Securities will have an aggregate
liquidation amount equal to 3% of the total capital of the Trust. The Common
Securities will generally rank on a par with the Preferred Securities. However,
in the case of certain defaults, the Common Securities will rank junior to the
Preferred Securities with respect to distributions and redemption and
liquidation payments.
 
                       Terms of the Preferred Securities
 
Distributions
 
   If you purchase Preferred Securities, you will be entitled to receive
cumulative cash distributions at an annual rate of      % of the $25
liquidation amount of each Preferred Security. Distributions will begin to
accumulate on the date of original issuance of the Preferred Securities which
is expected to be      , 1999 and will be payable quarterly, in arrears, on
March 31, June 30, September 30 and December 31 of each year beginning June 30,
1999.
 
Deferral of Distribution
 
   Reliant Energy can defer interest payments on the Junior Subordinated
Debentures for up to 20 consecutive quarterly periods unless an event of
default under the Junior Subordinated Debentures has occurred and is
continuing. Reliant Energy cannot, however, defer interest payments beyond the
maturity date of the Junior Subordinated Debentures (March 31, 2048).
Additional interest will accrue on any deferred interest payments at an annual
rate of    %, to the extent permitted by law.
 
   If Reliant Energy defers interest payments on the Junior Subordinated
Debentures, the Trust will also defer payment of distributions on the Common
and Preferred Securities. During a deferral period, distributions will continue
to accumulate on the Common and Preferred Securities at an annual rate of
     % of the liquidation amount of $25 per Common or Preferred Security. Also,
additional cash distributions will accumulate on any deferred distributions at
an annual rate of     % to the extent permitted by law.
 
                                      S-3
<PAGE>
 
 
   Once Reliant Energy makes all interest payments due on the Junior
Subordinated Debentures, including any additional interest, it can elect to
defer interest payments on the Junior Subordinated Debentures again if no event
of default under the Junior Subordinated Debentures has occurred and is
continuing, provided that such deferral period, together with all such previous
and further extensions thereof, may not exceed 20 consecutive quarters.
 
   During any period in which Reliant Energy defers interest payments on the
Junior Subordinated Debentures, Reliant Energy will not be permitted (subject
to certain exceptions described on page S-29) to:
 
  . pay a dividend or make any other payment or distribution on its capital
    stock;
 
  . redeem, purchase or acquire any of its capital stock;
  . make an interest, principal or premium payment, or repurchase or redeem,
    any of its debt securities that rank equal with or junior to the Junior
    Subordinated Debentures; or
  . make any guarantee payments with respect to any guarantee of the debt
    securities of any subsidiary that ranks equal with or junior to the
    Junior Subordinated Debentures.
 
   Should Reliant Energy exercise its rights to defer payments of interest on
the Junior Subordinated Debentures, you will be required to include accrued
distributions in your gross income for United States federal income tax
purposes before you actually receive the related cash distributions.
 
Redemption
 
   The Trust will redeem all of the outstanding Preferred Securities when the
Junior Subordinated Debentures are paid at maturity on March 31, 2048 or
otherwise become due. In addition, if Reliant Energy redeems any Junior
Subordinated Debentures before their maturity, the Trust will use the cash it
receives on the redemption of the Junior Subordinated Debentures to redeem, on
a pro rata basis, Preferred Securities and Common Securities having an
aggregate liquidation amount equal to the aggregate principal amount of the
Junior Subordinated Debentures redeemed.
 
   Reliant Energy will have the right to redeem some or all of the Junior
Subordinated Debentures before their maturity at 100% of their principal amount
(plus accrued and unpaid interest to, but excluding, the date of redemption) on
one or more occasions any time on or after           , 2004.
 
   Reliant Energy will also have the right to redeem the Junior Subordinated
Debentures, in whole but not in part, at any time at 100% at their principal
amount (plus accrued and unpaid interest to, but excluding, the date of
redemption), if (i) certain changes in tax or investment company law occur
(each of which is a "Special Event" and is more fully described on page S-15),
and (ii) the Junior Subordinated Debentures are redeemed within 90 days of the
occurrence of the Special Event.
 
Preferred Securities Guarantee
 
   Reliant Energy will fully and unconditionally guarantee the Trust's payment
obligations with respect to the Preferred Securities to the extent described in
this prospectus supplement and the accompanying prospectus. Under the Preferred
Securities Guarantee, Reliant Energy will guarantee the Trust's payment
obligations only to the extent the Trust has sufficient funds to make payments
on the Preferred Securities. If Reliant Energy does not make payments on the
Junior Subordinated Debentures, the Trust will not have sufficient funds to
make payments on the Preferred Securities. Reliant Energy's obligations under
the Preferred Securities Guarantee are junior to its obligations to make
payments on all of its other liabilities, except as discussed elsewhere in this
prospectus supplement.

<PAGE>
 
 
Conditional Right to Shorten Maturity
 
   Reliant Energy can shorten the stated maturity of the Junior Subordinated
Debentures to as early as     , 2018, if certain tax events relating to non-
deductibility of interest payments on the Junior Subordinated Debentures occur
(as more fully described on page S-30). If Reliant Energy exercises this
option, the Trust will redeem all of the outstanding Preferred Securities when
the Junior Subordinated Debentures are paid on their new maturity date.
 
Distribution of Junior Subordinated Debentures
 
   Reliant Energy has the right to dissolve the Trust at any time. If Reliant
Energy decides to exercise its right to dissolve the Trust, the Trust will
redeem the Preferred Securities by distributing the Junior Subordinated
Debentures to you and to Reliant Energy, as holder of the Common Securities, on
a pro rata basis. If the Trust distributes the Junior Subordinated Debentures,
Reliant Energy will use its best efforts to have the Junior Subordinated
Debentures listed on the New York Stock Exchange or on such other exchange or
automated quotation system as the Preferred Securities are then listed.
 
Liquidation Amount
 
   In the event the Trust is liquidated and the Junior Subordinated Debentures
are not distributed to you, you will generally be entitled to receive $25 per
Preferred Security plus an amount equal to any accumulated and unpaid
distributions on each Preferred Security to the date of payment.
 
Form of Preferred Securities
 
   The Preferred Securities will be represented by one or more global
securities that will be deposited with and registered in the name of Cede &
Co., as nominee for The Depository Trust Company ("DTC"). This means that you
will not receive a certificate for your Preferred Securities. Your beneficial
interest in the Preferred Securities will be evidenced by, and transfers
thereof will be effected only through, records maintained by the participants
in DTC. The Preferred Securities will be ready for delivery through DTC on or
about            , 1999.
 
Listing on the New York Stock Exchange
 
   The Trust intends to apply to have the Preferred Securities listed on the
New York Stock Exchange. If approved for listing, we expect trading to commence
within 30 days after the Preferred Securities are first issued. You should be
aware that the listing of the Preferred Securities will not necessarily ensure
that a liquid trading market will be available for the Preferred Securities.
 
Risk Factors
 
   You should pay special attention to the "Risk Factors" section beginning on
page S-6 of this prospectus supplement to determine whether an investment in
the Preferred Securities is appropriate for you.
 
                                      S-5
<PAGE>
 
                                  Risk Factors
 
   Your investment in the Preferred Securities will involve certain risks. You
should carefully consider the following discussion of risks and the other
information included or incorporated by reference in this prospectus supplement
and the accompanying prospectus before deciding whether an investment in the
Preferred Securities is appropriate for you.
 
Reliant Energy's obligations under the Junior Subordinated Debentures are
subordinated.
 
   Reliant Energy's obligations under the Junior Subordinated Debentures are
unsecured and will rank junior in priority of payment to its Senior Debt (as
more fully described on pages 16 and 17 of the accompanying prospectus). This
means that Reliant Energy cannot make any payments of principal (including
redemption payments) or interest on the Junior Subordinated Debentures if it
defaults on a payment on its Senior Debt. In the event of the bankruptcy,
liquidation or dissolution of Reliant Energy, its assets would be available to
pay obligations under the Junior Subordinated Debentures only after all
payments had been made on its Senior Debt. As of December 31, 1998, Reliant
Energy had approximately $4.6 billion of Senior Debt. Also, the Junior
Subordinated Debentures will be effectively subordinated to all indebtedness
and other obligations (including trade payables) of Reliant Energy's
subsidiaries. As of November 30, 1998, the indebtedness and other obligations
of Reliant Energy's subsidiaries totaled approximately $4.0 billion. Reliant
Energy's subsidiaries are separate and distinct legal entities and have no
obligation, contingent or otherwise, to pay any amounts due pursuant to the
Junior Subordinated Debentures or the Preferred Securities or to make any funds
available therefor, whether by dividends, loans or other payments, and do not
guarantee the payment of interest on or principal of the Junior Subordinated
Debentures or the Preferred Securities.
 
   The Preferred Securities, the Preferred Securities Guarantee and the Junior
Subordinated Debentures do not limit the ability of Reliant Energy and its
subsidiaries to incur additional indebtedness, including indebtedness that
ranks senior in priority of payment to the Junior Subordinated Debentures and
the Preferred Securities Guarantee.
 
The Preferred Securities Guarantee only guarantees payments if the Trust has
cash available.
 
   The ability of the Trust to pay distributions on the Preferred Securities,
the redemption price of the Preferred Securities and the liquidation amount of
each Preferred Security is solely dependent upon Reliant Energy making the
related payments on the Junior Subordinated Debentures when due.
 
   If Reliant Energy defaults on its obligations to pay principal or interest
on the Junior Subordinated Debentures, the Trust will not have sufficient funds
to pay distributions, the redemption price or the liquidation amount of each
Preferred Security. In those circumstances, you will not be able to rely upon
the Preferred Securities Guarantee for payment of these amounts.
 
   Instead, you may:
 
  . directly sue Reliant Energy or seek other remedies to collect your pro
    rata share of payments owed; or
 
  . rely on the Property Trustee to enforce the Trust's rights under the
    Junior Subordinated Debentures.
 
Reliant Energy's ability to defer interest payments on the Junior Subordinated
Debentures has tax consequences for you and may affect the market price of the
Preferred Securities.
 
   Reliant Energy can, on one or more occasions, defer interest payments on the
Junior Subordinated Debentures for up to 20 consecutive quarterly periods
unless an event of default under the Junior Subordinated Debentures has
occurred and is continuing. Reliant Energy, however, cannot defer interest
payments beyond the maturity date of the Junior Subordinated Debentures (March
31, 2048). If Reliant Energy defers interest payments on the Junior
Subordinated Debentures, the Trust will also defer payment of distributions on
the
 
                                      S-6
<PAGE>
 
Preferred and Common Securities. During a deferral period, distributions will
continue to accumulate on the Preferred and Common Securities. Also, additional
distributions will accumulate on any deferred distributions at an annual rate
of     % to the extent permitted by law.
 
   Should Reliant Energy exercise its right to defer payments of interest on
the Junior Subordinated Debentures, you will be required to accrue interest
income (as original issue discount) in respect of the deferred stated interest
allocable to your share of Preferred Securities for United States federal
income tax purposes. As a result, you will include such income in gross income
for United States federal income tax purposes prior to your receipt of any cash
distributions. In addition, you will not receive cash from the Trust related to
such income if you dispose of your Preferred Securities prior to the record
date on which distributions of such amounts are made. You should consult with
your own tax advisor with respect to the tax consequences of an investment in
the Preferred Securities.
 
   Reliant Energy does not currently intend to defer interest payments on the
Junior Subordinated Debentures. However, if Reliant Energy exercises its right
to defer interest payments in the future, the market price of the Preferred
Securities may not fully reflect the value of accrued but unpaid interest on
the Junior Subordinated Debentures. If you sell Preferred Securities during an
interest deferral period, you may not receive the same return on investment as
someone who continues to hold Preferred Securities. In addition, the existence
of Reliant Energy's right to defer interest payments on the Junior Subordinated
Debentures may mean that the market price for the Preferred Securities may be
more volatile than other securities that are not subject to these rights.
 
The Trust may redeem the Preferred Securities if certain tax changes occur or
if the trust is required to register as an "investment company."
 
   If a Special Event (as more fully described on page S-15) occurs and is
continuing, Reliant Energy has the right to redeem all of the Junior
Subordinated Debentures at a redemption price equal to 100% of the principal
amount plus accrued and unpaid interest to, but excluding, the redemption date.
If Reliant Energy redeems the Junior Subordinated Debentures upon the
occurrence of a Special Event, the Trust will use the cash it receives from the
redemption of the Junior Subordinated Debentures to redeem the Preferred and
Common Securities.
 
The Preferred Securities may be redeemed on or after             , 2004 at
Reliant Energy's option.
 
   Reliant Energy may redeem the Junior Subordinated Debentures at its option,
in whole or in part, at any time on or after             , 2004 at a redemption
price equal to 100% of the principal amount to be redeemed plus any accrued and
unpaid interest to, but excluding, the redemption date. You should assume that
Reliant Energy will exercise its redemption option if it is able to refinance
the Junior Subordinated Debentures at a lower interest rate or if it is
otherwise in the interest of Reliant Energy to redeem the Junior Subordinated
Debentures. If such a redemption occurs, the Trust will use the cash it
receives from the redemption of the Junior Subordinated Debentures to redeem an
equivalent amount of Preferred and Common Securities on a pro rata basis.
 
Reliant Energy can shorten the stated maturity of the Junior Subordinated
Debentures.
 
   Reliant Energy can shorten the stated maturity of the Junior Subordinated
Debentures to as early as     , 2018, if certain tax events relating to non-
deductibility of interest payments on the Junior Subordinated Debentures occur
(as more fully described on page S-30). If Reliant Energy exercises this
option, the Trust will redeem all of the Preferred and Common Securities when
the Junior Subordinated Debentures are paid on their new maturity date.
 
Distribution of the Junior Subordinated Debentures may have possible adverse
effects.
 
   Reliant Energy has the right to terminate the Trust at any time. If Reliant
Energy decides to exercise its right to terminate the Trust, the Trust will
redeem the Preferred and Common Securities by distributing the
 
                                      S-7
<PAGE>
 
Junior Subordinated Debentures to you and Reliant Energy, as holder of the
Common Securities, on a pro rata basis.
 
   Under current United States federal income tax laws, a distribution of
Junior Subordinated Debentures on the dissolution of the Trust would not be a
taxable event to you. Nevertheless, if the Trust is classified for United
States federal income tax purposes as an association taxable as a corporation
at the time it is dissolved, the distribution of the Junior Subordinated
Debentures would be a taxable event to you. In addition, if there is a change
in law, a distribution of Junior Subordinated Debentures on the dissolution of
the Trust could also be a taxable event to you.
 
   Reliant Energy has no current intention of causing the termination of the
Trust and the distribution of the Junior Subordinated Debentures. However,
there are no restrictions on its ability to do so at any time. Reliant Energy
anticipates that it would consider exercising this right in the event that
expenses associated with maintaining the Trust were substantially greater than
currently expected, such as if a Special Event occurred. Reliant Energy cannot
predict other circumstances under which this right would be exercised.
 
   Reliant Energy cannot predict the market prices for the Junior Subordinated
Debentures that may be distributed. Accordingly, the Junior Subordinated
Debentures that you receive on a distribution, or the Preferred Securities you
hold pending such a distribution, may trade at a discount to the price that you
paid to purchase the Preferred Securities.
 
   Because you may receive Junior Subordinated Debentures, you should make an
investment decision with regard to the Junior Subordinated Debentures in
addition to the Preferred Securities. You should carefully review all the
information regarding the Junior Subordinated Debentures contained in this
prospectus supplement and the accompanying prospectus.
 
Trading prices of the Preferred Securities may not reflect the value of accrued
but unpaid interest.
 
   The Preferred Securities constitute a new issue of securities with no
established trading market. The Preferred Securities may trade at a price that
does not fully reflect the value of accrued but unpaid interest with respect to
the underlying Junior Subordinated Debentures. If you dispose of your Preferred
Securities between record dates for payments of distributions thereon you will
be required to include accrued but unpaid interest on the Junior Subordinated
Debentures through the date of disposition in income as ordinary income, and to
add such amount to your adjusted tax basis in your pro rata share of the
underlying Junior Subordinated Debentures deemed disposed of. Accordingly, you
will recognize a capital loss to the extent the selling price (which may not
fully reflect the value of accrued but unpaid interest) is less than your
adjusted tax basis (which will include accrued but unpaid interest). Subject to
certain limited exceptions, capital losses cannot be applied to offset ordinary
income for United States federal income tax purposes.
 
There can be no assurance that an active market for the Preferred Securities
will develop.
 
   Prior to this offering, there has been no public market for the Preferred
Securities. The underwriters currently plan to make a market in the Preferred
Securities. However, we cannot assure you the underwriters will engage in such
activities or that an active trading market for the Preferred Securities will
develop or be sustained. If such a market were to develop, the Preferred
Securities could trade at prices that may be higher or lower than their
offering price depending upon many factors, including prevailing interest
rates, Reliant Energy's operating results and the markets for similar
securities.
 
You will have limited voting rights.
 
   As a holder of Preferred Securities, you will have limited voting rights
relating only to the modification of the Preferred Securities and, in certain
circumstances, the exercise of the Trust's rights as holder of the Junior
Subordinated Debentures and the Preferred Securities Guarantee. Only Reliant
Energy can replace or remove any of the Trustees or increase or decrease the
number of Trustees.

                                Use of Proceeds
 
   The Trust will invest all of the proceeds from the sale of the Preferred
Securities in Junior Subordinated Debentures issued by Reliant Energy. Reliant
Energy anticipates that the net proceeds from the sale of the Junior
Subordinated Debentures will be used for general corporate purposes, including
the repayment of Reliant Energy's indebtedness, including indebtedness to
subsidiaries. Repayment of Reliant Energy's indebtedness to subsidiaries will
be reflected on Reliant Energy's consolidated financial statements as repayment
of maturing short-term debt, having interest rates ranging from 5% to 6%.
 
                              Accounting Treatment
 
   For financial reporting purposes, the Trust will be treated as a subsidiary
of Reliant Energy and, accordingly, the accounts of the Trust will be included
in the financial statements of Reliant Energy. The Preferred Securities will be
reflected in the consolidated balance sheets of Reliant Energy as "Company
Obligated Mandatorily Redeemable Preferred Securities of Subsidiary Trusts
Holding Solely Junior Subordinated Debentures of Company," and appropriate
disclosures about the Preferred Securities, the Preferred Securities Guarantee
and the Junior Subordinated Debentures will be included in Reliant Energy's
notes to consolidated financial statements. For financial reporting purposes,
Reliant Energy will record Distributions payable on the Preferred Securities as
a non-operating expense.

                                 Reliant Energy
 
   Reliant Energy is a diversified international energy services company.
Reliant Energy HL&P ("HL&P"), the Company's electric utility division, serves
approximately 1.6 million customers in the City of Houston, Texas, and
surrounding areas of the Texas Gulf Coast. Reliant Energy Resources Corp.
("Reliant Resources"), the Company's largest subsidiary, is a natural gas
utility serving over 2.8 million customers in Arkansas, Louisiana, Minnesota,
Mississippi, Oklahoma and Texas. Reliant Resources, through its subsidiaries,
is also a major interstate natural gas pipeline company and a provider of
energy marketing services.
 
   Reliant Energy's other principal subsidiaries include (i) Reliant Energy
International, Inc. ("Reliant International"), which participates in the
privatization of foreign generating and distribution facilities and the
development and acquisition of foreign independent power projects and (ii)
Reliant Energy Power Generation, Inc., which participates in the acquisition,
development and operation of domestic non-rate regulated power generation
facilities.
 
   Reliant Energy, subject to certain limited exceptions, is exempt from
regulation as a public utility holding company pursuant to Section 3(a)(2) of
the Public Utility Holding Company Act of 1935, as amended.
 
Recent Developments
 
   On January 28, 1999, Reliant Energy reported a consolidated net loss for the
year ended December 31, 1998 of $142 million ($.50 per share) compared to
consolidated net income for the year ended December 31, 1997 of $421 million
($1.66 per share). The consolidated net loss reported for 1998 is primarily a
function of the accounting treatment of Reliant Energy's Automatic Common
Exchange Securities (the "ACES") which were issued in July 1997. Reliant Energy
recorded a non-cash, unrealized accounting loss of $764 million on the ACES in
1998. In 1997, Reliant Energy recorded a non-cash, unrealized accounting loss
of $79 million on the ACES, which was partially offset by $37 million of non-
recurring interest income related to a refund of federal income taxes in 1997.
 
   After adjusting for non-recurring and other charges in both years as
discussed above, net income for 1998 would have been $622 million ($2.19 per
share) compared to $463 million ($1.83 per share) in 1997. The increase in
adjusted net income for 1998 as compared to 1997 was due to strong results from
Reliant Energy's interstate pipeline, wholesale energy and international
segments. Earnings in 1998 included an $80 million ($.28 per share) gain on the
sale of an electric distribution system in Argentina. Also contributing to the
increase in 1998 earnings were earnings from the businesses acquired in the
August 1997 acquisition of Reliant Resources. These effects were partially
offset by additional depreciation of regulated power generation assets in
compliance with HL&P's rate of return cap and increased interest expense
primarily related to the acquisition of Reliant Resources.
 
   Reliant Energy recently announced that it expects to record a charge to its
earnings in the first quarter of 1999 as a result of the recent currency
devaluation in Brazil. The charge will reflect the impact of changes in the
currency value of the Brazilian real on the foreign currency denominated debt
(primarily U.S. dollars) of certain Brazilian corporations in which Reliant
Energy has an ownership interest. Reliant Energy will not be able to calculate
the amount of the charge until the end of the first quarter of 1999.
 
                                  REI Trust I
 
   REI Trust I, formerly named HI Trust I (the "Trust"), is a statutory
business trust created on January 11, 1999 under the Delaware Business Trust
Act pursuant to a declaration of trust among the Trustees and Reliant Energy
and the filing of a certificate of trust with the Secretary of State of the
State of Delaware. Such declaration will be amended and restated in its
entirety (as so amended and restated, the "Declaration") as of
 
                                      S-11
<PAGE>
 
the date the Trust initially issues the Preferred Securities. The Declaration
will be qualified under the Trust Indenture Act of 1939, as amended (the "Trust
Indenture Act").
 
   The Trust will initially have five Trustees. Three of the Trustees will be
officers or employees of Reliant Energy. The Bank of New York will act as the
Property Trustee of the Trust and The Bank of New York (Delaware) will act as
the Delaware Trustee of the Trust.
 
   Upon the issuance of the Preferred Securities, the holders thereof will own
all of the issued and outstanding Preferred Securities of the Trust. Reliant
Energy will, directly or indirectly, acquire common securities representing
common undivided beneficial interests in the assets of the Trust (the "Common
Securities" and, together with the Preferred Securities, the "Trust
Securities") in an amount equal to at least 3% of the total capital of the
Trust and will own, directly or indirectly, all of the issued and outstanding
Common Securities of the Trust.
 
   The Trust exists for the purposes of (a) issuing the Preferred Securities,
(b) issuing the Common Securities to Reliant Energy, (c) investing the gross
proceeds from the sale of the Trust Securities in Junior Subordinated
Debentures of Reliant Energy and (d) engaging in only such other activities as
are necessary, convenient or incidental thereto or are specifically authorized
in the Declaration.
 
   The rights of the holders of the Trust Securities, including economic
rights, rights to information and voting rights, are as set forth in the
Declaration, the Delaware Business Trust Act and the Trust Indenture Act. In
the Declaration, Reliant Energy has agreed to pay for all debts and obligations
(other than with respect to the Trust Securities) and all costs and expenses of
the Trust, including the fees and expenses of the Trustees and any taxes to
which the Trust may become subject, except for United States withholding taxes,
and all costs and expenses with respect thereto.
 
                    Description of the Preferred Securities
 
   The Preferred Securities will be issued pursuant to the terms of the
Declaration which is qualified under the Trust Indenture Act. The Bank of New
York, as Property Trustee, but not the other Trustees of the Trust, will act as
the indenture trustee under the Declaration for purposes of the Trust Indenture
Act. The terms of the Preferred Securities and the Declaration include those
stated in the Declaration and those made part of the Declaration by the Trust
Indenture Act and the Delaware Business Trust Act. The following summarizes the
material terms and provisions of the Preferred Securities and is qualified in
its entirety by reference to the Declaration, the Delaware Business Trust Act
and the Trust Indenture Act.
 
General
 
   The Declaration authorizes the Trust to issue the Preferred Securities,
which represent preferred undivided beneficial interests in the assets of the
Trust, and the Common Securities, which represent common undivided beneficial
interests in the assets of the Trust. All of the Common Securities will be
owned, directly or indirectly, by Reliant Energy. The Common Securities and the
Preferred Securities rank pari passu with each other and will have equivalent
terms except that (i) if a Declaration Event of Default occurs and is
continuing, the rights of the holders of the Common Securities to payment in
respect of periodic Distributions and payments upon liquidation, redemption or
otherwise will be subordinated to the rights of the holders of the Preferred
Securities and (ii) holders of Common Securities will have the exclusive right
to appoint, remove or replace the Trustees and to increase or decrease the
number of Trustees.
 
   The Declaration does not permit:
 
  . the issuance by the Trust of any securities or other evidences of
    beneficial ownership of, or beneficial interests in, the Trust other than
    the Preferred Securities and the Common Securities;
 
  . the incurrence of any indebtedness for borrowed money by the Trust; or
 
  . the making of any investment other than in the Junior Subordinated
    Debentures.
 
                                      S-12
<PAGE>
 
   Pursuant to the Declaration, the Property Trustee will own and hold the
Junior Subordinated Debentures as trust assets for the benefit of the holders
of the Preferred Securities and the Common Securities. The payment of
Distributions out of moneys held by the Property Trustee and payments on
redemption of the Preferred Securities or liquidation of the Trust are
guaranteed by Reliant Energy on a subordinated basis as and to the extent
described in this prospectus supplement under "Description of the Preferred
Securities Guarantee" and in the accompanying prospectus under "Description of
the Preferred Securities Guarantees." The Property Trustee will hold the
Preferred Securities Guarantee for the benefit of holders of the Preferred
Securities. The Preferred Securities Guarantee is a full and unconditional
guarantee from the time of issuance of the Preferred Securities, but the
Preferred Securities Guarantee covers Distributions and other payments on the
Preferred Securities only if and to the extent that Reliant Energy has made a
payment to the Property Trustee of interest or principal on the Junior
Subordinated Debentures.
 
Distributions
 
   Distributions on the Preferred Securities will be fixed at an annual rate of
    % of the $25 liquidation amount of each Preferred Security. Distributions
in arrears for more than one calendar quarter will accumulate additional
distributions at the rate per annum of     % (to the extent permitted by law),
compounded quarterly. The term "Distributions" as used herein means such
periodic cash distributions and any such additional distributions unless
otherwise stated. The amount of Distributions payable for any period will be
computed on the basis of a 360-day year of twelve 30-day months, and for any
period shorter than a full quarterly Distribution period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed per 90-day quarter.
 
   Distributions on the Preferred Securities will accumulate from the date of
original issuance of the Preferred Securities which is expected to be
          , 1999, and, except as otherwise described below, will be payable
quarterly in arrears on March 31, June 30, September 30 and December 31 of each
year, commencing on June 30, 1999, but only if, and to the extent that,
interest payments are made in respect of the Junior Subordinated Debentures
held by the Property Trustee.
 
 Option to Defer Distributions
 
   As long as it is not in default in the payment of interest on the Junior
Subordinated Debentures, Reliant Energy has the right under the Indenture to
defer payments of interest on the Junior Subordinated Debentures by extending
the interest payment period at any time and from time to time on the Junior
Subordinated Debentures for a period not exceeding 20 consecutive quarterly
interest periods. During any Extension Period (as hereinafter defined) no
interest will be due and payable on the Junior Subordinated Debentures. As a
consequence, Distributions will also be deferred. Despite such deferral,
Distributions will continue to accumulate with additional distributions thereon
(to the extent permitted by applicable law but not at a rate greater than the
rate at which interest is then accruing on the Junior Subordinated Debentures)
at the rate of     % per annum, compounded quarterly during any such Extension
Period; provided that no such Extension Period may extend beyond the stated
maturity of the Junior Subordinated Debentures. For a description of certain
restrictions that will be placed upon Reliant Energy during an Extension
Period, see "Description of the Junior Subordinated Debentures--Option to
Extend Interest Payment Period."
 
   Prior to the termination of any Extension Period, Reliant Energy may further
extend it; provided that such Extension Period together with all such previous
and further extensions thereof may not exceed 20 consecutive quarterly interest
periods. Upon the termination of any Extension Period and the payment of all
amounts then due, Reliant Energy may commence a new Extension Period, subject
to the above requirements. Reliant Energy may also prepay at any time all or
any portion of the interest accrued during an Extension Period. Consequently,
there could be multiple Extension Periods of varying lengths throughout the
term of the Junior Subordinated Debentures, not to exceed 20 consecutive
quarters or to cause any extension beyond the maturity of the Junior
Subordinated Debentures. See "Risk Factors--Reliant Energy's ability to defer
interest payments on the Junior Subordinated Debentures has tax consequences
for you and may affect the market price of the
 
                                      S-13
<PAGE>
 
Preferred Securities," "Description of the Junior Subordinated Debentures--
Interest" and "--Option to Extend Interest Payment Period" herein. Payments of
accumulated Distributions will be payable to holders of Preferred Securities as
they appear on the books and records of the Trust on the first record date
after the end of an Extension Period.
 
 Payment of Distributions
 
   Distributions on the Preferred Securities will be paid on the dates payable
to the extent that the Property Trustee has cash on hand in a segregated non-
interest bearing banking account (the "Property Account") to permit such
payment. The funds available for distribution to the holders of the Preferred
Securities will be limited to payments received by the Property Trustee in
respect of the Junior Subordinated Debentures. If Reliant Energy does not make
interest payments on the Junior Subordinated Debentures, the Property Trustee
will not make Distributions on the Preferred Securities. Under the Declaration,
if and to the extent Reliant Energy does make interest payments on the Junior
Subordinated Debentures deposited in the Trust as trust assets, the Property
Trustee is obligated to make Distributions on the Trust Securities on a pro
rata basis. The payment of Distributions on the Preferred Securities is
guaranteed by Reliant Energy on a subordinated basis as and to the extent
described in this prospectus supplement under "Description of the Preferred
Securities Guarantee" and in the accompanying prospectus under "Description of
the Preferred Securities Guarantees." The Preferred Securities Guarantee is a
full and unconditional guarantee from the time of issuance of the Preferred
Securities, but the Preferred Securities Guarantee covers Distributions and
other payments on the Preferred Securities only if and to the extent that
Reliant Energy has made a payment to the Property Trustee of interest or
principal on the Junior Subordinated Debentures.
 
 Method of Payment of Distributions
 
   Distributions on the Preferred Securities will be made to the holders
thereof as they appear on the books and records of the Trust on the relevant
record dates, which, as long as the Preferred Securities remain in book-entry
form, will be one Business Day (as defined below) prior to the relevant
Distribution payment date. Distributions payable on any Preferred Securities
that are not punctually paid on any Distribution payment date as a result of
Reliant Energy's failure to make the corresponding interest payment on the
Junior Subordinated Debentures will forthwith cease to be payable to the person
in whose name such Preferred Security is registered on the relevant record
date, and such defaulted Distribution will instead be payable to the person in
whose name such Preferred Security is registered on the special record date
established by the Regular Trustees, which record date shall correspond to the
special record date or other specified date determined in accordance with the
Indenture; provided, however, that Distributions will not be considered payable
on any Distribution payment date falling within an Extension Period unless
Reliant Energy has elected to make a full or partial payment of interest
accrued on the Junior Subordinated Debentures on such Distribution payment
date. Distributions on the Preferred Securities will be paid through the
Property Trustee who will hold amounts received in respect of the Junior
Subordinated Debentures in the Property Account for the benefit of the holders
of the Preferred Securities and the Common Securities. Subject to any
applicable laws and regulations and the provisions of the Declaration, each
such payment will be made as described under "--Book-Entry Only Issuance--The
Depository Trust Company" below. In the event that the Preferred Securities do
not continue to remain in book-entry form, the relevant record dates will be
the fifteenth day of the month prior to the relevant Distribution payment date.
The Declaration provides that the payment dates or record dates for the
Preferred Securities will be the same as the payment dates and record dates for
the Junior Subordinated Debentures. All Distributions paid with respect to the
Trust Securities will be paid on a pro rata basis to the holders thereof
entitled thereto. If any date on which Distributions are to be made is not a
Business Day, then payment of the Distribution to be made on such date will be
made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay) except that, if such
Business Day is in the next succeeding calendar year, such payment shall be
made on the immediately preceding Business Day, in each case with the same
force and effect as if made on the date such payment was originally payable.
"Business Day" means any day other than a Saturday or Sunday or a day on which
banking institutions in the Borough of Manhattan, the City and State of New
York, New York or Houston, Texas are authorized or required by law to close.

Special Event Redemption
 
   If a Tax Event or an Investment Company Event (each, a "Special Event") has
occurred and is continuing, Reliant Energy will have the right to redeem the
Junior Subordinated Debentures, in whole but not in part, and therefore cause a
mandatory redemption of the Trust Securities, in whole but not in part, at the
Redemption Price (the liquidation amount plus accumulated and unpaid
Distributions) within 90 days following the occurrence of such Special Event.
 
   "Tax Event" means that Reliant Energy and the Regular Trustees have received
an opinion of counsel experienced in such matters to the effect that on or
after the date of this prospectus supplement as a result of:
 
  . any amendment to, or change (including any announced prospective change)
    in, the laws (or any regulations thereunder) of the United States or any
    political subdivision or taxing authority thereof or therein;
 
  . any amendment to, or change in, an interpretation or application of any
    such laws or regulations by any legislative body, court, governmental
    agency or regulatory authority (including the enactment of any
    legislation and the publication of any judicial decision or regulatory
    determination);
 
  . any interpretation or pronouncement by any legislative body, court,
    governmental agency or regulatory authority that provides for a position
    with respect to such laws or regulations that differs from the
    theretofore generally accepted position; or
 
  . any action taken by any governmental agency or regulatory authority;
 
which amendment or change is enacted, promulgated, issued or announced or which
interpretation or pronouncement is issued or announced or which action is
taken, in each case on or after the date of this prospectus supplement, there
is more than an insubstantial risk that:
 
  . the Trust is, or will be within 90 days of the date thereof, subject to
    United States federal income tax with respect to income accrued or
    received on the Junior Subordinated Debentures;
 
  . the Trust is, or will be within 90 days of the date thereof, subject to
    more than a de minimis amount of taxes, duties or other governmental
    charges; or
 
  . interest payable by Reliant Energy to the Trust on the Junior
    Subordinated Debentures is not, or within 90 days of the date thereof
    will not be, deductible by Reliant Energy for United States federal
    income tax purposes.
 
   "Investment Company Event" means that Reliant Energy and the Regular
Trustees shall have received an opinion of counsel experienced in practice
under the Investment Company Act of 1940, as amended (the "Investment Company
Act") that as a result of the occurrence of a change in law or regulation or a
change in interpretation or application of law or regulation by any legislative
body, court, governmental agency or regulatory authority (a "Change in
Investment Company Act Law"), there is more than an insubstantial risk that the
Trust is or will be considered an "investment company" which is required to be
registered under the Investment Company Act, which Change in Investment Company
Act Law becomes effective on or after the date of this prospectus supplement.
 
Distribution of the Junior Subordinated Debentures
 
   At any time, Reliant Energy, as the holder of the Common Securities, may, in
its sole discretion, dissolve the Trust and, after satisfaction of liabilities
to creditors of the Trust as provided by applicable law, cause the Junior
Subordinated Debentures to be distributed to the holders of the Trust
Securities.
 
   If Junior Subordinated Debentures are distributed to the holders of the
Trust Securities upon the dissolution and liquidation of the Trust, the Junior
Subordinated Debentures will be issued in denominations of $25 and integral
multiples thereof. If distributed to holders of the Trust Securities, it is
anticipated that the Junior Subordinated Debentures would be distributed in the
form of one or more global securities and DTC, or any successor depositary for
the Preferred Securities, would act as depositary for the Junior Subordinated
Debentures. The depositary arrangements for the Junior Subordinated Debentures
would be substantially similar
 
                                      S-15
<PAGE>
 
to those in effect for the Preferred Securities. None of Reliant Energy, the
Indenture Trustee, any paying agent or any other agent of Reliant Energy or the
Indenture Trustee will have any responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership
interests in a global security for such Junior Subordinated Debentures or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.
 
   For a description of the Depository (as defined in the Declaration) and the
terms of the depository arrangements relating to payments, transfers, voting
rights, redemption and other notices and other matters relating to the Junior
Subordinated Debentures, see "Description of the Junior Subordinated
Debentures--Book-Entry and Settlement."
 
   On the date fixed for any distribution of Junior Subordinated Debentures,
upon dissolution of the Trust, (i) the Preferred Securities, the Preferred
Securities Guarantee and the Common Securities will no longer be deemed to be
outstanding and (ii) any certificates representing Preferred Securities will be
deemed to represent beneficial interests in the Junior Subordinated Debentures
having an aggregate principal amount equal to the aggregate stated liquidation
amount of, and bearing accrued and unpaid interest equal to accumulated and
unpaid Distributions on, such Preferred Securities, until such certificates are
presented to Reliant Energy or its agent for transfer or reissuance.
 
   There can be no assurance as to the market price for the Junior Subordinated
Debentures which may be distributed in exchange for Preferred Securities if a
dissolution and liquidation of the Trust were to occur. Accordingly, the Junior
Subordinated Debentures which a holder of Preferred Securities may subsequently
receive on dissolution and liquidation of the Trust, may trade at a discount to
the price of the Preferred Securities exchanged. If the Junior Subordinated
Debentures are distributed to the holders of Preferred Securities upon the
dissolution of the Trust, Reliant Energy will use its best efforts to list the
Junior Subordinated Debentures on the New York Stock Exchange or on such other
exchange or automated quotation system on which the Preferred Securities are
then listed.
 
Mandatory Redemption
 
   Upon the repayment of the Junior Subordinated Debentures, in whole or in
part, whether at maturity, upon redemption or otherwise, the proceeds from such
repayment will be promptly applied to redeem on a pro rata basis Preferred
Securities and Common Securities having an aggregate liquidation amount equal
to the aggregate principal amount of the Junior Subordinated Debentures so
repaid or redeemed, upon not less than 30 nor more than 60 days' notice, at the
Redemption Price. The Common Securities will be entitled to be redeemed on a
pro rata basis with the Preferred Securities, except that if an Event of
Default under the Declaration has occurred and is continuing, the Preferred
Securities will have a priority over the Common Securities with respect to
payment of the Redemption Price. Subject to the foregoing, if fewer than all
outstanding Preferred Securities and Common Securities are to be redeemed, the
Preferred Securities and Common Securities will be redeemed on a pro rata
basis.
 
Redemption Procedures
 
   The Trust may not redeem fewer than all outstanding Preferred Securities
unless all accumulated and unpaid Distributions have been paid on all Preferred
Securities for all quarterly Distribution periods terminating on or prior to
the date of redemption.
 
   If the Trust gives a notice of redemption in respect of a redemption of
Preferred Securities (which notice will be irrevocable) then, while the
Preferred Securities are still in book-entry only form, by 12:00 noon, New York
City time, on the Redemption Date and provided that Reliant Energy has paid to
the Property Trustee a sufficient amount of cash in connection with the related
redemption or maturity of the Junior Subordinated Debentures, the Property
Trustee will irrevocably deposit with the Depositary (as hereinafter defined)
funds sufficient to pay the applicable Redemption Price and will give the
Depositary irrevocable instructions and
 
                                      S-16
<PAGE>
 
authority to pay the Redemption Price to the holders of the Preferred
Securities. See "--Book-Entry Only Issuance--The Depository Trust Company." If
notice of redemption shall have been given and funds deposited as required,
then, immediately prior to the close of business on the Redemption Date,
Distributions will cease to accumulate on the Preferred Securities called for
redemption, such Preferred Securities will no longer be deemed to be
outstanding and all rights of holders of such Preferred Securities so called
for redemption will cease, except the right of the holders of such Preferred
Securities to receive the Redemption Price, but without interest on such
Redemption Price. Neither the Trustees nor the Trust shall be required to
register or cause to be registered the transfer of any Preferred Securities
which have been so called for redemption. If any date fixed for redemption of
Preferred Securities is not a Business Day, then payment of the Redemption
Price payable on such date will be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of any such
delay) except that, if such Business Day falls in the next calendar year, such
payment will be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date fixed for redemption. If
payment of the Redemption Price in respect of Preferred Securities is
improperly withheld or refused and not paid by the Property Trustee or by
Reliant Energy pursuant to the Preferred Securities Guarantee, Distributions on
such Preferred Securities will continue to accumulate, from the original
redemption date of the Preferred Securities to the date of payment, in which
case the actual payment date will be considered the date fixed for redemption
for purposes of calculating the Redemption Price.
 
   In the event that fewer than all of the outstanding Preferred Securities are
to be redeemed, the Preferred Securities will be redeemed as described below
under "--Book-Entry Only Issuance--The Depository Trust Company."
 
   If a partial redemption of the Preferred Securities would result in the
delisting of the Preferred Securities by any national securities exchange or
other organization on which the Preferred Securities are then listed or traded,
Reliant Energy will redeem Junior Subordinated Debentures only in whole and, as
a result, under such circumstances the Trust may redeem the Preferred
Securities only in whole. Subject to the foregoing and applicable law
(including, without limitation, United States federal securities laws), Reliant
Energy or any of its subsidiaries may at any time and from time to time
purchase outstanding Preferred Securities by tender, in the open market or by
private agreement.
 
Liquidation Distribution Upon Dissolution
 
   In the event of any voluntary or involuntary dissolution, winding-up or
termination of the Trust, the holders of the Preferred Securities and the
Common Securities at the date of the dissolution, winding-up or termination of
the Trust, as the case may be, will be entitled to receive, on a pro rata basis
solely out of the assets of the Trust legally available for distribution to
holders of Preferred Securities and Common Securities after satisfaction of
liabilities to the creditors of the Trust, an amount equal to the aggregate of
the stated liquidation amount of $25 per Trust Security plus accumulated and
unpaid Distributions thereon to the date of payment (such amount being the
"Liquidation Distribution"), unless, in connection with such dissolution,
winding-up or termination, and after satisfaction of liabilities to the
creditors of the Trust, Junior Subordinated Debentures, in an aggregate
principal amount equal to the aggregate stated liquidation amount of such Trust
Securities and bearing accrued and unpaid interest in an amount equal to the
accumulated and unpaid Distributions on such Trust Securities, shall be
distributed on a pro rata basis to the holders of the Preferred Securities and
the Common Securities in exchange therefor.
 
   If, upon any such dissolution, winding-up or termination, the Liquidation
Distribution can be paid only in part because the Trust has insufficient assets
on hand legally available to pay in full the aggregate Liquidation
Distribution, then the amounts payable directly by the Trust on the Preferred
Securities and the Common Securities shall be paid on a pro rata basis. The
holders of the Common Securities will be entitled to receive Liquidation
Distributions upon any such dissolution, winding-up or termination on a pro
rata basis with the holders of the Preferred Securities, except that if an
Event of Default under the Declaration has occurred and is continuing, the
Preferred Securities shall have a priority over the Common Securities with
respect to the payment of the Liquidation Distribution.
 
                                      S-17
<PAGE>
 
   Pursuant to the Declaration, the Trust will dissolve:
 
  . on December 31, 2053, the expiration of the term of the Trust;
 
  . when all of the Trust Securities have been called for redemption and the
    amounts necessary for redemption thereof have been paid to the holders of
    Trust Securities in accordance with the terms of the Trust Securities;
 
  . when all of the Junior Subordinated Debentures have been distributed to
    the holders of Trust Securities in exchange for all of the Trust
    Securities in accordance with the terms of the Trust Securities; or
 
  . upon a decree of judicial dissolution.
 
Merger, Consolidation or Amalgamation of the Trust
 
   The Trust may not consolidate, convert into, amalgamate, merge with or into,
or be replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to, any corporation or other body, except as
described below. The Trust may, at the request of Reliant Energy, with the
consent of the Regular Trustees and without the consent of the holders of the
Trust Securities, the Delaware Trustee or the Property Trustee, consolidate,
convert into, amalgamate, merge with or into, or be replaced by, or convey,
transfer or lease its properties and assets substantially as an entirety to, a
trust organized as such under the laws of any State; provided, that:
 
  . such successor entity either:
 
    . expressly assumes all of the obligations of the Trust under the Trust
      Securities and the Declaration; or
 
    . substitutes for the Trust Securities other securities having
      substantially the same terms as the Trust Securities (the "Successor
      Securities"), so long as the Successor Securities rank the same as
      the Trust Securities rank with respect to Distributions and payments
      upon liquidation, redemption and otherwise;
 
  . Reliant Energy expressly appoints a trustee of such successor entity
    possessing the same powers and duties as the Property Trustee as the
    holder of the Junior Subordinated Debentures;
 
  . the Preferred Securities are listed, or any Successor Securities will be
    listed upon notification of issuance, on any national securities exchange
    or with another organization on which the Preferred Securities are then
    listed or quoted;
 
  . such merger, conversion, consolidation, amalgamation, replacement,
    conveyance, transfer or lease does not cause the Preferred Securities
    (including any Successor Securities) or the Junior Subordinated
    Debentures to be downgraded by any nationally recognized statistical
    rating organization;
 
  . such merger, conversion, consolidation, amalgamation, replacement,
    conveyance, transfer or lease does not adversely affect the rights,
    preferences and privileges of the holders of the Trust Securities
    (including any Successor Securities) in any material respect (other than
    with respect to any dilution of the holders' interest in the new entity);
 
  . such successor entity has purposes substantially identical to those of
    the Trust;
 
  . prior to such merger, conversion, consolidation, amalgamation,
    replacement, conveyance, transfer or lease, Reliant Energy has received
    an opinion of counsel experienced in such matters to the effect that;
 
    . such merger, conversion, consolidation, amalgamation, replacement,
      conveyance, transfer or lease does not adversely affect the rights,
      preferences and privileges of the holders of the Trust Securities
      (including any Successor Securities) in any material respect (other
      than with respect to any dilution of the holders' interest in the new
      entity);
 
    . following such merger, conversion, consolidation, amalgamation,
      replacement, conveyance, transfer or lease, neither the Trust nor
      such successor entity will be required to register as an investment
      company under the Investment Company Act; and
 
                                      S-18
<PAGE>
 
    . following such merger, conversion, consolidation, amalgamation,
      replacement, conveyance, transfer or lease, the Trust or such
      successor entity will continue to be classified as a grantor trust for
      United States federal income tax purposes;
 
  . Reliant Energy or any other permitted successor or assignee owns all of
    the common securities of such successor entity and guarantees the
    obligations of such successor entity under the Successor Securities at
    least to the extent provided by the Preferred Securities Guarantee; and
 
  . there shall have been furnished to the Property Trustee an officers'
    certificate and an opinion of counsel relating to the satisfaction of all
    conditions precedent in the Declaration.
 
   Notwithstanding the foregoing, the Trust will not, except with the consent
of holders of 100% in liquidation amount of the Trust Securities, consolidate,
amalgamate, merge with or into, convert into, or be replaced by or convey,
transfer or lease its properties and assets as an entirety or substantially as
an entirety to, any other entity or permit any other entity to consolidate,
amalgamate, merge with or into, or replace it, if such consolidation,
amalgamation, merger, conversion, replacement, conveyance, transfer or lease
would cause the Trust or the Successor Entity to be classified as other than a
grantor trust for United States federal income tax purposes or would cause the
holders of the Trust Securities not to be treated as owning an undivided
interest in the Junior Subordinated Debentures.
 
Declaration Events of Default
 
   An Indenture Event of Default will constitute an event of default under the
Declaration with respect to the Trust Securities (a "Declaration Event of
Default"); provided that pursuant to the Declaration, the holder of the Common
Securities will be deemed to have waived any such Declaration Event of Default
with respect to the Common Securities until all Declaration Events of Default
with respect to the Preferred Securities have been cured, waived or otherwise
eliminated. Until all such Declaration Events of Default with respect to the
Preferred Securities have been so cured, waived or otherwise eliminated, the
Property Trustee will be deemed to be acting solely on behalf of the holders
of the Preferred Securities, and only the holders of the Preferred Securities
will have the right to direct the Property Trustee with respect to certain
matters under the Declaration and consequently under the Indenture. In the
event that any Declaration Event of Default with respect to the Preferred
Securities is waived by the holders of the Preferred Securities as provided in
the Declaration, the holders of Common Securities pursuant to the Declaration
have agreed that such waiver also constitutes a waiver of such Declaration
Event of Default with respect to the Common Securities for all purposes under
the Declaration without any further act, vote or consent of the holders of the
Common Securities.
 
   Upon the occurrence of a Declaration Event of Default, the Property
Trustee, subject to the limitations described below under "--Voting Rights,"
as the holder of all of the Junior Subordinated Debentures will have the right
under the Indenture to declare the principal of and interest on the Junior
Subordinated Debentures to be immediately due and payable. In addition, the
Property Trustee will, subject to the limitations described below under
"--Voting Rights," have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Indenture Trustee.
 
Voting Rights
 
   Except as provided below, under "--Modification and Amendment of the
Declaration" below and "Description of the Preferred Securities Guarantees--
Amendments and Assignment" in the accompanying prospectus and as otherwise
required by the Delaware Business Trust Act, the Trust Indenture Act and the
Declaration, the holders of the Preferred Securities will have no voting
rights.
 
   So long as any Junior Subordinated Debentures are held by the Property
Trustee, the Trustees will not:
 
  . direct the time, method and place of conducting any proceeding for any
    remedy available to the Indenture Trustee or exercising any trust or
    power conferred on the Indenture Trustee with respect to the Junior
    Subordinated Debentures;
 
  . waive any past default that is waivable under Section 6.06 of the
    Indenture; or
 
                                     S-19
<PAGE>
 
  . exercise any right to rescind or annul a declaration of acceleration of
    the maturity of the principal of the Junior Subordinated Debentures;
 
without, in each case, obtaining the prior approval of the holders of a
majority in liquidation amount of all outstanding Preferred Securities and
Common Securities. The Trustees shall not revoke any action previously
authorized or approved by a vote of the holders of the Preferred Securities
except by subsequent vote of such holders. The Property Trustee will notify
each holder of Preferred Securities of any notice of default with respect to
the Junior Subordinated Debentures. In addition to obtaining the foregoing
approvals of such holders of the Preferred Securities and Common Securities,
prior to taking any of the foregoing actions, the Trustees will obtain an
opinion of counsel experienced in such matters to the effect that for United
States federal income tax purposes the Trust will not be classified as other
than a grantor trust on account of such action.
 
   If a Declaration Event of Default has occurred and is continuing, then the
holders of a majority in liquidation amount of the Preferred Securities will
have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Property Trustee or to direct the
exercise of any trust or power conferred upon the Property Trustee under the
Declaration, including the right to direct the Property Trustee to exercise the
remedies available to it as a holder of the Junior Subordinated Debentures. If
the Property Trustee fails to enforce its rights under the Junior Subordinated
Debentures, a holder of Preferred Securities, to the extent permitted by
applicable law, may, after a period of 30 days has elapsed from such holder's
written request to the Property Trustee to enforce such rights, institute a
legal proceeding directly against Reliant Energy to enforce the Property
Trustee's rights under the Junior Subordinated Debentures without first
instituting any legal proceeding against the Property Trustee or any other
person or entity; provided further, that if a Declaration Event of Default has
occurred and is continuing and such event is attributed to the failure of
Reliant Energy to pay interest or principal on the Junior Subordinated
Debentures on the date such interest or principal is otherwise payable (or in
the case of redemption, on the redemption date), then a holder of Preferred
Securities may directly institute a proceeding for enforcement of payment to
such holder of the principal of or interest on the Junior Subordinated
Debentures having a principal amount equal to the aggregate liquidation amount
of the Preferred Securities of such holder (a "Direct Action") on or after the
respective due date specified in the Junior Subordinated Debentures. In
connection with such Direct Action, Reliant Energy will be subrogated to the
rights of such holder of Preferred Securities to the extent of any payment made
by Reliant Energy to such holders of Preferred Securities in such Direct
Action. Except as provided in the preceding sentences, the holders of Preferred
Securities will not be able to exercise directly any other remedy available to
the holders of the Junior Subordinated Debentures. See "The Trusts--The
Property Trustee" in the accompanying prospectus.
 
   A waiver of an Indenture Event of Default by the Property Trustee at the
direction of holders of the Preferred Securities will constitute a waiver of
the corresponding Declaration Event of Default in respect of the Trust
Securities.
 
   In the event the consent of the Property Trustee as the holder of the Junior
Subordinated Debentures is required under the Indenture with respect to any
amendment, modification or termination of the Indenture or the Junior
Subordinated Debentures, the Property Trustee will request the written
direction of the holders of the Trust Securities with respect to such
amendment, modification or termination and shall vote with respect to such
amendment, modification or termination as directed by a majority in liquidation
amount of the Trust Securities voting together as a single class; provided,
however, that where any such amendment, modification or termination under the
Indenture would require the consent or vote of holders of Junior Subordinated
Debentures representing a specified percentage greater than a majority in
principal amount of the Junior Subordinated Debentures, the Property Trustee
may only vote with respect to that amendment, modification or termination as
directed by the vote of holders of Trust Securities representing such specified
percentage of the aggregate liquidation amount of the Trust Securities; and,
provided, further, that the Property Trustee will be under no obligation to
take any action in accordance with the directions of the holders of the Trust
Securities unless the Property Trustee has received an opinion of counsel
experienced in such matters to the effect that the Trust will not be classified
for United States federal income tax purposes as other than a grantor trust on
account of such action.
 
                                      S-20
<PAGE>
 
   Any required approval or direction of holders of Preferred Securities may be
given at a separate meeting of holders of Preferred Securities convened for
such purpose, at a meeting of all of the holders of Trust Securities or
pursuant to written consent. The Regular Trustees will cause a notice of any
meeting at which holders of Preferred Securities are entitled to vote, or of
any matter upon which action by written consent of such holders is to be taken,
to be mailed to each holder of record of Preferred Securities. Each such notice
will include a statement setting forth:
 
  . the date of such meeting or the date by which such action is to be taken;
 
  . a description of any resolution proposed for adoption at such meeting on
    which such holders are entitled to vote or of such matter upon which
    written consent is sought; and
 
  . instructions for the delivery of proxies or consents.
 
   No vote or consent of the holders of Preferred Securities will be required
for the Trust to redeem and cancel Preferred Securities or to distribute the
Junior Subordinated Debentures in accordance with the Declaration.
Notwithstanding that holders of Preferred Securities are entitled to vote or
consent under any of the circumstances described above, any of the Preferred
Securities at such time that are owned by Reliant Energy or by any affiliate of
Reliant Energy will not be entitled to vote or consent and shall, for purposes
of such vote or consent, be treated as if they were not outstanding.
 
   The procedures by which persons owning Preferred Securities registered in
the name of and held by DTC or its nominee may exercise their voting rights are
described under "--Book-Entry Only Issuance--The Depository Trust Company"
below.
 
   Holders of Preferred Securities will have no rights to increase or decrease
the number of Trustees or to appoint, remove or replace a Trustee, which rights
are vested exclusively in the holders of the Common Securities.
 
Modification and Amendment of the Declaration
 
   The Declaration may be modified and amended on approval of a majority of the
Regular Trustees, provided, that if any proposed modification or amendment
provides for, or the Regular Trustees otherwise propose to effect:
 
  . any action that would adversely affect the powers, preferences or special
    rights of the Trust Securities, whether by way of amendment to the
    Declaration (other than as described below) or otherwise; or
 
  . the dissolution, winding-up or termination of the Trust other than
    pursuant to the terms of the Declaration;
 
then the holders of the outstanding Trust Securities as a single class will be
entitled to vote on such amendment or proposal, and such amendment or proposal
will not be effective except with the approval of at least a majority in
liquidation amount of the Trust Securities, provided that if any amendment or
proposal referred to above would adversely affect only the Preferred Securities
or the Common Securities, then only the affected class of Trust Securities will
be entitled to vote on such amendment or proposal and such amendment or
proposal shall not be effective except with the approval of a majority in
liquidation amount of such class of Trust Securities.
 
   Notwithstanding the foregoing, no amendment or modification may be made to
the Declaration:
 
  . unless the Regular Trustees shall have first received (i) an officers'
    certificate from Reliant Energy that such amendment is permitted by, and
    conforms to, the terms of the Declaration and (ii) an opinion of counsel
    that such amendment is permitted by, and conforms to, the terms of the
    Declaration and that all conditions precedent, if any, in the Declaration
    to the execution and delivery of such amendment have been satisfied; and
 
  . to the extent the result of such amendment would be to (i) cause the
    Trust to fail to continue to be classified for purposes of United States
    federal income taxation as a grantor trust, (ii) reduce or otherwise
    adversely affect the powers of the Property Trustee in contravention of
    the Trust Indenture
 
                                      S-21
<PAGE>
 
    Act or (iii) cause the Trust to be deemed to be an "investment company"
    required to be registered under the Investment Company Act.
 
   Certain specified provisions of the Declaration may not be amended without
the consent of all of the holders of the Trust Securities. No amendment which
adversely affects the rights, powers and privileges of the Property Trustee or
the Delaware Trustee may be made without the consent of the Property Trustee or
Delaware Trustee, respectively. Article IV of the Declaration relating to the
obligation of Reliant Energy to purchase the Common Securities and to pay
certain obligations and expenses of the Trust as described under "The Trusts"
in the accompanying prospectus may not be amended without the consent of
Reliant Energy. The rights of holders of Common Securities under Article V of
the Declaration to increase or decrease the number of, and to appoint, replace
or remove Trustees shall not be amended without the consent of each holder of
Common Securities.
 
   The Declaration further provides that it may be amended without the consent
of the holders of the Trust Securities to:
 
  . cure any ambiguity;
 
  . correct or supplement any provision in the Declaration that may be
    defective or inconsistent with any other provision of the Declaration;
 
  . add to the covenants, restrictions or obligations of Reliant Energy;
 
  . conform to changes in, or a change in interpretation or application of
    certain Investment Company Act regulations by the Securities and Exchange
    Commission;
 
  . make any other provisions with respect to matters or questions arising
    under the Declaration which shall not be inconsistent with the other
    provisions of the Declaration;
 
  . modify, eliminate or add to any provisions of the Declaration to such
    extent as shall be necessary to ensure that the Trust will be classified
    for United States federal income tax purposes as a grantor trust at all
    times that any Trust Securities are outstanding or to ensure that the
    Trust will not be required to register as an "investment company" under
    the Investment Company Act; and
 
  . evidence the acceptance of the appointment of a successor Trustee or fill
    a vacancy created by an increase in the number of Regular Trustees;
 
which amendment does not adversely affect in any material respect the rights,
preferences or privileges of the holders.
 
Book-Entry Only Issuance--The Depository Trust Company
 
   The Depository Trust Company ("DTC") will act as securities depositary for
the Preferred Securities (the "Depositary"). The Preferred Securities will be
issued only as fully registered securities registered in the name of DTC or its
nominee. One or more fully-registered global Preferred Securities certificates
(each a "Preferred Securities Global Certificate"), representing the total
aggregate number of Preferred Securities, will be issued and will be deposited
with DTC or pursuant to DTC's instructions.
 
   The laws of some jurisdictions require that certain purchasers of securities
take physical delivery of securities in definitive form. Such laws may impair
the ability to transfer beneficial interests in a global Preferred Securities.
 
   DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"). DTC holds securities that its
participants ("Direct Participants") deposit with
 
                                      S-22
<PAGE>
 
DTC. DTC also facilitates the settlement among Direct Participants of
securities transactions, such as transfers and pledges, in deposited securities
through electronic computerized book-entry changes in Direct Participants'
accounts, thereby eliminating the need for physical movement of securities
certificates. Direct Participants include securities brokers and dealers,
banks, trust companies, clearing corporations and certain other organizations.
DTC is owned by a number of its Direct Participants and by the New York Stock
Exchange, Inc., the American Stock Exchange, Inc., and the National Association
of Securities Dealers, Inc. Access to the DTC system is also available to
others such as securities brokers and dealers, banks and trust companies that
clear through or maintain a custodial relationship with a Direct Participant,
either directly or indirectly ("Indirect Participants"). Direct Participants
and Indirect Participants are collectively referred to herein as
"Participants." The rules applicable to DTC and its Participants are on file
with the Securities and Exchange Commission.
 
   Upon issuance of a Preferred Securities Global Certificate, DTC will credit
on its book-entry registration and transfer system the number of Preferred
Securities represented by such Preferred Securities Global Certificate to the
accounts of institutions that have accounts with DTC. Ownership of beneficial
interests in a Preferred Securities Global Certificate will be limited to
Participants or persons that may hold interests through Participants. The
ownership interest of each actual purchaser of each Preferred Security
("Beneficial Owner") is in turn to be recorded on the Direct and Indirect
Participants' records. Beneficial Owners will not receive written confirmation
from DTC of their purchases, but Beneficial Owners are expected to receive
written confirmations providing details of the transactions, as well as
periodic statements of their holdings, from the Direct or Indirect Participants
through which the Beneficial Owners purchased Preferred Securities. Transfers
of ownership interests in the Preferred Securities are to be accomplished by
entries made on the books of Participants acting on behalf of Beneficial
Owners. Beneficial Owners will not receive certificates representing their
ownership interests in the Preferred Securities, except in the event that use
of the book-entry system for the Preferred Securities is discontinued.
 
   DTC has no knowledge of the actual Beneficial Owners of the Preferred
Securities; DTC's records reflect only the identity of the Direct Participants
to whose accounts such Preferred Securities are credited, which may or may not
be the Beneficial Owners. The Participants will remain responsible for keeping
account of their holdings on behalf of their customers. So long as DTC, or its
nominee, is the owner of a Preferred Securities Global Certificate, DTC or such
nominee, as the case may be, will be considered the sole owner and holder of
record of the Preferred Securities represented by such Preferred Securities
Global Certificate for all purposes.
 
   Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
   While DTC is acting as the securities depository for the Preferred
Securities, redemption notices will be sent by Reliant Energy and the Trust
directly to DTC. DTC will then inform the Direct Participants, who will then
contact the Beneficial Owners. If less than all of the Preferred Securities are
being redeemed, DTC's practice is to determine by lot the interest of each
Direct Participant to be redeemed.
 
   Although voting with respect to the Preferred Securities is limited, in
those instances in which a vote is required, neither DTC nor Cede & Co. will
consent or vote with respect to Preferred Securities. Under its usual
procedures, DTC would mail an Omnibus Proxy to the Trust as soon as possible
after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting or
voting rights to those Direct Participants to whose accounts the Preferred
Securities are credited on the record date (identified in a listing attached to
the Omnibus Proxy).
 
   Distribution payments on the Preferred Securities represented by a Preferred
Series Global Certificate will be made by the Property Trustee to DTC. DTC's
practice is to credit Direct Participants' accounts on the relevant payment
date in accordance with their respective holdings shown on DTC's records unless
DTC has reason to believe that it will not receive payments on such payment
date. Payments by Participants to Beneficial Owners will be governed by
standing instructions and customary practices and will be the
 
                                      S-23
<PAGE>
 
responsibility of such Participants and not of DTC, the Trust or Reliant
Energy, subject to any statutory or regulatory requirements as may be in effect
from time to time. Payment of Distributions to DTC is the responsibility of the
Trust, disbursement of such payments to Direct Participants is the
responsibility of DTC, and disbursement of such payments to the Beneficial
Owners is the responsibility of Direct and Indirect Participants.
 
   Except as provided herein, a Beneficial Owner will not be entitled to
receive physical delivery of Preferred Securities. Accordingly, each Beneficial
Owner must rely on the procedures of DTC to exercise any rights under the
Preferred Securities.
 
   DTC may discontinue providing its services as securities depository with
respect to the Preferred Securities at any time by giving reasonable notice to
the Trust. Under such circumstances, if a successor securities depository is
not obtained, Preferred Securities certificates will be required to be printed
and delivered. Additionally, the Trust may decide to discontinue use of the
system of book-entry transfers through DTC (or a successor depository). In that
event, certificates for the Preferred Securities will be printed and delivered.
 
   Under the Declaration, payments made by the Trust to DTC or its nominee will
satisfy the Trust's obligations under the Declaration, to the extent of the
payments so made. Beneficial owners will not be, and will not be considered by
the Trust to be, and will not have any rights as owners of Preferred Securities
under the Declaration.
 
   The Trust, Reliant Energy and the Trustees will have no responsibility or
obligation to any Direct Participant, Indirect Participant or any Beneficial
Owner or any other person not shown on the registration books of the Trust as
being a registered owner with respect to: (1) the accuracy of any records
maintained by DTC or any Direct Participant or Indirect Participant, (2) the
payment of any amount due by DTC to any direct participant or by any Direct
Participant or Indirect Participant to any Beneficial Owner in respect of
Distributions, (3) the delivery of any notice by DTC to any Direct Participant
or by any Direct Participant or Indirect Participant to any Beneficial Owner
that is required or permitted to be given to registered owners under the terms
of the Declaration, (4) the selection of the Beneficial Owners to receive
payment in the event of any practical redemption of the Preferred Securities or
(5) any consent given or other action taken by DTC as a registered owner.
 
   The Trustee and the Trust, so long as a book-entry only system is used for
the Preferred Securities, will send any notice of redemption or of proposed
document amendments requiring consent of registered owners and any other
notices required by the document to be sent to registered owners only to DTC
(or any successor securities depository) or its nominee. Any failure of DTC to
advise any Direct Participant, or of any Direct Participant or Indirect
Participant to notify the Beneficial Owner, of any such notice and its content
or effect will not affect the validity of the redemption of the Preferred
Securities called for redemption, the document amendment or any other action
premised on that notice.
 
   The Trust, Reliant Energy and the Trustees cannot and do not give any
assurances that DTC will distribute Distributions and other payments on the
Preferred Securities made to DTC or its nominee as the registered owner or any
redemption or other notices to the Participants, or that the Participants or
others will distribute such payments or notices to the Beneficial Owners, or
that they will do so on a timely basis, or that DTC will serve and act in the
manner described in this prospectus supplement. Beneficial Owners should make
appropriate arrangements with their broker or dealer regarding distribution of
information regarding the Preferred Securities that may be transmitted by or
through DTC.
 
   The foregoing information concerning DTC and DTC's book-entry system is
based upon information obtained from DTC and contains statements that are
believed to describe accurately DTC, the method of effecting book-entry
transfers of securities distributed through DTC and certain related matters,
but neither the Trust nor Reliant Energy take any responsibility for the
accuracy of such statements.

Registrar, Transfer Agent and Paying Agent
 
   In the event the Preferred Securities do not remain in book-entry only form,
the following provisions will apply.
 
   Payment of Distributions and payments on redemption of the Preferred
Securities will be payable, the transfer of the Preferred Securities will be
registrable, and Preferred Securities will be exchangeable for Preferred
Securities of other denominations of a like aggregate liquidation amount at the
corporate trust office of the Property Trustee in New York, New York; provided
that payment of Distributions may be made at the option of the Regular Trustees
on behalf of the Trust by check mailed to the address of the persons entitled
thereto and that the payment on redemption of any Preferred Security will be
made only upon surrender of such Preferred Security to the Property Trustee.
 
   The Bank of New York or one of its affiliates will act as registrar and
transfer agent for the Preferred Securities. The Bank of New York will also act
as paying agent and, with the consent of the Regular Trustees, may designate
additional paying agents.
 
   Registration of transfers of Preferred Securities will be effected without
charge by or on behalf of the Trust but only upon payment (with the giving of
such indemnity as the Regular Trustees may require) in respect of any tax or
other governmental charges that may be imposed in relation to it.
 
   The Trust will not be required to register or cause to be registered the
transfer of Preferred Securities after such Preferred Securities have been
called for redemption.
 
Information Concerning the Property Trustee
 
   The Property Trustee, prior to the occurrence of a Declaration Event of
Default and after the curing of all Declaration Events of Default that may have
occurred, will undertake to perform only such duties as are specifically set
forth in the Declaration and, after the occurrence of a Declaration Event of
Default (that has not been cured or waived), shall exercise such of the rights
and powers vested in it by the Declaration and use the same degree of care and
skill in their exercise, as a prudent individual would exercise or use under
the circumstances in the conduct of his or her own affairs. The Property
Trustee is under no obligation to exercise any of the powers vested in it by
the Declaration at the request of any holder of Preferred Securities, unless
offered reasonable security and indemnity by such holder against the costs,
expenses and liabilities which might be incurred thereby. The Property Trustee
is not required to expend or risk its own funds or otherwise incur personal
financial liability in the performance of its duties if the Property Trustee
has reasonable grounds for believing that the repayment of such funds or
liability or adequate indemnity against such risk or liability is not
reasonably assured to it.
 
   Reliant Energy and its subsidiaries maintain commercial banking and trust
relationships with the Property Trustee and its affiliates.
 
Governing Law
 
   The Declaration and the Preferred Securities will be governed by, and
construed in accordance with, the laws of the State of Delaware.
 
Miscellaneous
 
   The Regular Trustees are authorized and directed to take such action as they
determine in their discretion to be necessary or desirable in carrying out the
purposes of the Trust, including, but not limited to:
 
  . causing the Trust not to be deemed to be an "investment company" required
    to be registered under the Investment Company Act;
 
  . causing the Trust to be classified for United States federal income tax
    purposes as a grantor trust; and
 
  . cooperating with Reliant Energy to ensure that the Junior Subordinated
    Debentures will be treated as indebtedness of Reliant Energy for United
    States federal income tax purposes.
 
                                      S-25
<PAGE>
 
   In this connection, the Regular Trustees are authorized to take any action
not inconsistent with applicable law, the certificate of trust or the
Declaration that the Regular Trustees determine in their discretion to be
reasonable and necessary or desirable for such purposes.
 
   Reliant Energy and the Regular Trustees on behalf of the Trust will be
required to provide to the Property Trustee annually a certificate as to
whether or not Reliant Energy and the Trust, respectively, are in compliance
with all the conditions and covenants under the Declaration.
 
               Description of the Preferred Securities Guarantee
 
   Pursuant to the Preferred Securities Guarantee, Reliant Energy will
irrevocably and unconditionally agree, to the extent set forth therein, to pay
in full to the holders of the Preferred Securities, the Guarantee Payments (as
defined in the accompanying prospectus) (without duplication of amounts
theretofore paid by the Trust) as and when due, regardless of any defense,
right of set-off or counterclaim which the Trust may have or assert. Reliant
Energy's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by Reliant Energy to the holders of Preferred
Securities or by causing the Trust to pay such amounts to such holders. The
Preferred Securities Guarantee will be qualified as an indenture under the
Trust Indenture Act. The Bank of New York will act as indenture trustee under
the Preferred Securities Guarantee (the "Guarantee Trustee"). The terms of the
Preferred Securities Guarantee will be those set forth in such Preferred
Securities Guarantee and those made part of such Preferred Securities Guarantee
by the Trust Indenture Act. The Preferred Securities Guarantee will be held by
the Guarantee Trustee for the benefit of the holders of the Preferred
Securities. A summary description of the Preferred Securities Guarantee appears
in the accompanying prospectus under the caption "Description of the Preferred
Securities Guarantees."
 
               Description of the Junior Subordinated Debentures
 
   Set forth below is a description of the Junior Subordinated Debentures in
which the Trust will invest the proceeds from the issuance and sale of the
Trust Securities and which will be deposited in the Trust as trust assets. The
terms of the Junior Subordinated Debentures include those stated in the Junior
Subordinated Indenture dated as of February 15, 1999 between Reliant Energy and
The Bank of New York, as trustee (the "Indenture Trustee"), as supplemented by
Supplemental Indenture No. 1 dated as of February 15, 1999 between Reliant
Energy and the Indenture Trustee (as so supplemented, the "Indenture") and
those made part of the Indenture by the Trust Indenture Act. This description
supplements the description of the general terms and provisions of the Junior
Subordinated Debentures set forth in the accompanying prospectus under the
caption "Description of the Junior Subordinated Debt Securities." The following
description does not purport to be complete and is qualified in its entirety by
reference to the Indenture and the Trust Indenture Act. Whenever particular
provisions or defined terms in the Indenture are referred to herein, such
provisions or defined terms are incorporated by reference herein.
 
   The Indenture does not limit the aggregate principal amount of indebtedness
which may be issued thereunder and provides that junior subordinated debentures
may be issued thereunder from time to time in one or more series. The Junior
Subordinated Debentures constitute a separate series under the Indenture.
 
   Under certain circumstances involving the dissolution of the Trust, Junior
Subordinated Debentures may be distributed to the holders of the Trust
Securities in liquidation of the Trust. See "Description of the Preferred
Securities--Distribution of the Junior Subordinated Debentures."
 
General
 
   The Junior Subordinated Debentures are unsecured, subordinated obligations
of Reliant Energy, limited in aggregate principal amount to an amount equal to
the sum of:
 
  . the stated liquidation amount of the Preferred Securities issued by the
    Trust; and
 
  . the proceeds received by the Trust upon issuance of the Common Securities
    to Reliant Energy (which proceeds will be used to purchase an equivalent
    principal amount of Junior Subordinated Debentures).
 
                                      S-26
<PAGE>
 
   The entire principal amount of the Junior Subordinated Debentures will
become due and payable, together with any accrued and unpaid interest thereon,
on March 31, 2048, unless such maturity date is shortened by Reliant Energy as
described herein under "--Reliant Energy's Right to Shorten Maturity." The
Junior Subordinated Debentures are not subject to any sinking fund.
 
   If Junior Subordinated Debentures are distributed to holders of Preferred
Securities upon the dissolution of the Trust, such Junior Subordinated
Debentures will initially be issued as a Global Security (as defined below). As
described herein, under certain limited circumstances, Junior Subordinated
Debentures may be issued in certificated form in exchange for a Global
Security. See "--Book-Entry and Settlement" below. In the event that Junior
Subordinated Debentures are issued in certificated form, such Junior
Subordinated Debentures will be in denominations of $25 and integral multiples
thereof and may be transferred or exchanged at the offices described below.
Payments on Junior Subordinated Debentures issued as a Global Security will be
made to DTC, a successor depositary, or in the event that no depositary is
used, to a paying agent for the Junior Subordinated Debentures.
 
   In the event that Junior Subordinated Debentures are issued in certificated
form, payments of principal and interest will be payable, the transfer of the
Junior Subordinated Debentures will be registrable, and Junior Subordinated
Debentures will be exchangeable for Junior Subordinated Debentures of other
denominations of a like aggregate principal amount at the corporate trust
office of the Indenture Trustee in New York, New York; provided that payment of
interest may be made at the option of Reliant Energy by check mailed to the
address of the persons entitled thereto and that the payment of principal with
respect to any Junior Subordinated Debenture will be made only upon surrender
of such Junior Subordinated Debenture to the Indenture Trustee.
 
Optional Redemption
 
   Except as provided below, the Junior Subordinated Debentures may not be
redeemed prior to          , 2004. Reliant Energy shall have the right to
redeem the Junior Subordinated Debentures, in whole or in part, from time to
time, on or after         , 2004, upon not less than 30 nor more than 60 days'
notice, at 100% of the principal amount of the Junior Subordinated Debentures
together with accrued and unpaid interest, including Compounded Interest (as
hereinafter defined) to, but excluding, the redemption date.
 
   If the Junior Subordinated Debentures are redeemed on any Interest Payment
Date (as defined below), accrued and unpaid interest shall be payable to
holders of record on the relevant record date.
 
   So long as the Trust Securities are outstanding, the proceeds from the
redemption of any Junior Subordinated Debentures will be used to redeem Trust
Securities.
 
   Reliant Energy will also have the right to redeem the Junior Subordinated
Debentures, in whole but not in part, within 90 days following the occurrence
of a Special Event as described under "Description of the Preferred
Securities--Special Event Redemption."
 
   Reliant Energy may not redeem any Junior Subordinated Debentures unless all
accrued and unpaid interest thereon, including Compounded Interest, if any, has
been paid for all quarterly periods terminating on or prior to the date of
notice of redemption.
 
   If Reliant Energy gives a notice of redemption in respect of Junior
Subordinated Debentures (which notice will be irrevocable), then by 12:00 noon,
New York City time, on the redemption date, Reliant Energy will deposit
irrevocably with the Indenture Trustee funds sufficient to pay the applicable
Redemption Price and will give irrevocable instructions and authority to pay
such Redemption Price to the holders of the Junior Subordinated Debentures. If
notice of redemption shall have been given and funds deposited as required,
then immediately prior to the close of business on the redemption date interest
will cease to accrue on the Junior Subordinated Debentures called for
redemption, such Junior Subordinated Debentures will no longer be deemed to be
outstanding and all rights of holders of such Junior Subordinated Debentures so
called for redemption will
 
                                      S-27
<PAGE>
 
cease, except the right of the holders of such Junior Subordinated Debentures
to receive the applicable Redemption Price but without interest on such
Redemption Price. If any date fixed for redemption of Junior Subordinated
Debentures is not a Business Day, then payment of the Redemption Price payable
on such date will be made on the next succeeding day that is a Business Day
(and without any interest or other payment in respect of any such delay) except
that, if such Business Day falls in the next calendar year, such payment will
be made on the immediately preceding Business Day, in each case with the same
force and effect as if made on such date fixed for redemption. If Reliant
Energy fails to repay the Junior Subordinated Debentures on maturity or the
date fixed for redemption or if payment of the Redemption Price in respect of
Junior Subordinated Debentures is improperly withheld or refused and not paid
by Reliant Energy, interest on such Junior Subordinated Debentures will
continue to accrue from the original redemption date to the date of payment, in
which case the actual payment date will be considered the date fixed for
redemption for purposes of calculating the applicable Redemption Price. If
fewer than all of the Junior Subordinated Debentures are to be redeemed, the
Junior Subordinated Debentures will be redeemed pro rata or by lot or by any
other method utilized by the Indenture Trustee.
 
   In the event of any redemption in part, Reliant Energy will not be required
to:
 
  . issue, register the transfer of, or exchange any Junior Subordinated
    Debentures during a period beginning at the opening of business 15 days
    before the mailing of a notice of redemption of Junior Subordinated
    Debentures and ending at the close of business on the date of such
    mailing; and
 
  . register the transfer of or exchange any Junior Subordinated Debentures
    so selected for redemption, in whole or in part, except the unredeemed
    portion of any Junior Subordinated Debentures being redeemed in part.
 
Interest
 
   The Junior Subordinated Debentures will bear interest at the rate of     %
per annum from the date of original issuance of the Junior Subordinated
Debentures which is expected to be            , 1999. Interest will be payable
quarterly in arrears on March 31, June 30, September 30 and December 31 of each
year (each, an "Interest Payment Date"), commencing on June 30, 1999, to the
person in whose name such Junior Subordinated Debenture is registered, subject
to certain exceptions, at the close of business on the Business Day next
preceding such Interest Payment Date. In the event (i) the Preferred Securities
shall not continue to remain in book-entry only form or (ii) if following
distribution of the Junior Subordinated Debentures to holders of Trust
Securities upon dissolution of the Trust as described under "Description of the
Preferred Securities--Distribution of the Junior Subordinated Debentures," the
Junior Subordinated Debentures shall not continue to remain in book-entry only
form, the relevant record date will be the fifteenth day of the month in which
the relevant Interest Payment Date occurs. Interest payable on any Junior
Subordinated Debenture that is not punctually paid or duly provided for on any
Interest Payment Date will forthwith cease to be payable to the person in whose
name such Junior Subordinated Debenture is registered on the relevant record
date, and such defaulted interest will instead be payable to the person in
whose name such Junior Subordinated Debenture is registered on the special
record date or other specified date determined in accordance with the
Indenture; provided, however, that interest shall not be considered payable by
Reliant Energy on any Interest Payment Date falling within an Extension Period
unless Reliant Energy has elected to make a full or partial payment of interest
accrued on the Junior Subordinated Debentures on such Interest Payment Date.
The amount of interest payable for any full quarterly interest period will be
computed on the basis of a 360-day year of twelve 30-day months, and for any
period shorter than a full quarterly interest period for which interest is
computed, interest will be computed on the basis of the actual number of days
elapsed per 90-day quarter. If any date on which interest is payable on the
Junior Subordinated Debentures is not a Business Day, then payment of the
interest payable on such date will be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of any such
delay), except that, if such Business Day is in the next succeeding calendar
year, such payment shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on the date such payment
was originally payable.

<PAGE>
 
Option to Extend Interest Payment Period
 
   So long as Reliant Energy is not in default in the payment of interest on
the Junior Subordinated Debentures, Reliant Energy will have the right to defer
payments of interest on the Junior Subordinated Debentures by extending the
interest payment period at any time from time to time for an extension period
not exceeding 20 consecutive quarterly interest periods (each such period, an
"Extension Period"). Reliant Energy has no current intention of exercising its
right to extend an interest payment period. No interest will be due and payable
on the Junior Subordinated Debentures during an Extension Period, except at the
end thereof. During any Extension Period, Reliant Energy will not:
 
  . declare or pay any dividends on, or redeem, purchase, acquire or make a
    distribution or liquidation payment with respect to, any of its capital
    stock other than:
 
    . dividends or distributions in shares of, or options, warrants, rights
      to subscribe for or purchase shares of, Reliant Energy's common
      stock;
 
    . any declaration of a dividend in connection with the implementation
      of a shareholders' rights plan, or the issuance of stock under any
      such plan in the future, or the redemption or repurchase of any such
      rights pursuant thereto;
 
    . as a result of a reclassification of Reliant Energy's capital stock
      or the exchange or the conversion of one class or series of Reliant
      Energy's capital stock for another class or series of Reliant
      Energy's capital stock;
 
    . the payment of accrued dividends and the purchase of fractional
      interests in shares of Reliant Energy's capital stock pursuant to the
      conversion or exchange provisions of such capital stock or the
      security being converted or exchanged; or
 
    . purchases of Reliant Energy's common stock related to the issuance of
      Reliant Energy's common stock or rights under any of Reliant Energy's
      benefit plans for its directors, officers, employees, any of Reliant
      Energy's dividend reinvestment plans or stock purchase plans, or any
      of the benefit plans of any of Reliant Energy's affiliates for such
      affiliates' directors, officers or employees;
 
  . make any payment of principal or of interest or premium, if any, on or
    repay, repurchase or redeem any debt security of Reliant Energy that,
    ranks pari passu with or junior in interest to the Junior Subordinated
    Debentures; or
 
  . make any guarantee payments with respect to any guarantee by Reliant
    Energy of the debt securities of any subsidiary of Reliant Energy (other
    than the Preferred Securities Guarantee) if such guarantee ranks pari
    passu with or junior in interest to the Junior Subordinated Debentures.
 
   Prior to the termination of any such Extension Period, Reliant Energy may
further extend such Extension Period; provided that such Extension Period
together with all such previous and further extensions thereof may not exceed
20 consecutive quarterly interest periods or extend beyond the maturity of the
Junior Subordinated Debentures. On the Interest Payment Date occurring at the
end of each Extension Period, Reliant Energy will pay to the holders of Junior
Subordinated Debentures of record on the record date for such Interest Payment
Date (regardless of who the holders of record may have been on other dates
during the Extension Period) all accrued and unpaid interest on the Junior
Subordinated Debentures, together with interest thereon at the rate specified
for the Junior Subordinated Debentures to the extent permitted by applicable
law, compounded quarterly ("Compounded Interest"). Upon the termination of any
Extension Period and the payment of all amounts then due, Reliant Energy may
commence a new Extension Period, subject to the above requirements. Reliant
Energy may also prepay at any time all or any portion of the interest accrued
during an Extension Period. Consequently, there could be multiple Extension
Periods of varying lengths throughout the term of the Junior Subordinated
Debentures, not to exceed 20 consecutive quarterly interest periods; provided,
that no such period may extend beyond the stated maturity of the Junior
Subordinated Debentures. The failure by Reliant Energy to make interest
payments during an Extension Period would not constitute a default or an event
of default under the Indenture or Reliant Energy's currently outstanding
indebtedness.
 
                                      S-29
<PAGE>
 
   If the Property Trustee is the sole holder of the Junior Subordinated
Debentures, Reliant Energy will give the Property Trustee notice of its
election to begin an Extension Period one Business Day prior to the earlier of:
 
  . the next succeeding date on which Distributions on the Preferred
    Securities are payable; or
 
  . the date the Trust is required to give notice to the New York Stock
    Exchange or other applicable self-regulatory organization or to holders
    of the Preferred Securities of the record date or the date such
    Distribution is payable.
 
   The Trust will give notice of Reliant Energy's election to begin such
Extension Period to the holders of the Preferred Securities.
 
   If Junior Subordinated Debentures have been distributed to holders of Trust
Securities, Reliant Energy will give the holders of the Junior Subordinated
Debentures notice of its election to begin an Extension Period at least ten
Business Days prior to the earlier of:
 
  . the next succeeding Interest Payment Date; or
 
  . the date Reliant Energy is required to give notice to the New York Stock
    Exchange (if the Junior Subordinated Debentures are then listed thereon)
    or other applicable self-regulatory organization or to holders of the
    Junior Subordinated Debentures of the record or payment date of such
    related interest payment.
 
Additional Interest
 
   If at any time the Trust shall be required to pay any taxes, duties,
assessments or governmental charges of whatever nature (other than withholding
taxes) imposed by the U.S. or any other taxing authority, then, in any such
case, Reliant Energy will pay as additional interest ("Additional Interest") on
the Junior Subordinated Debentures such additional amounts as shall be required
so that the net amounts received and retained by the Trust after paying any
such taxes, duties, assessments or other governmental charges will be equal to
the amounts the Trust would have received had no such taxes, duties,
assessments or other governmental charges been imposed.
 
Compounded Interest
 
   Payments of Compounded Interest on the Junior Subordinated Debentures held
by the Trust will make funds available to pay additional cash distributions on
Distributions in arrears in respect of the Preferred Securities pursuant to the
terms thereof.
 
Reliant Energy's Right to Shorten Maturity
 
   If a Tax Event occurs, then Reliant Energy will have the right (i) prior to
the dissolution of the Trust, to shorten the stated maturity of the Junior
Subordinated Debentures to the minimum extent required, but not less than 19
and one-half years from the date of original issuance thereof, or (ii) to
direct the Property Trustee to dissolve the Trust (if not previously dissolved)
and shorten the stated maturity of the Junior Subordinated Debentures to the
minimum extent required, but not less than 19 and one-half years from the date
of original issuance thereof, in each case such that in the opinion of counsel
to Reliant Energy experienced in such matters, after shortening the stated
maturity, interest paid on the Junior Subordinated Debentures will be
deductible for federal income tax purposes.
 
   If Reliant Energy exercises its right and shortens the stated maturity of
the Junior Subordinated Debentures, the Trust will redeem all of the
outstanding Preferred Securities when the Junior Subordinated Debentures are
paid on their new maturity date.

Book-Entry and Settlement
 
   If any Junior Subordinated Debentures are distributed to holders of
Preferred Securities (see "Description of the Preferred Securities--
Distribution of the Junior Subordinated Debentures"), such Junior Subordinated
Debentures will be issued in the form of one or more global certificates (each
a "Global Security") registered in the name of the Depositary or its nominee.
Except under the limited circumstances described below, Junior Subordinated
Debentures represented by the Global Security will not be exchangeable for, and
will not otherwise be issuable as, Junior Subordinated Debentures in definitive
form. The Global Securities described above may not be transferred except by
the Depositary to a nominee of the Depositary or by a nominee of the Depositary
to the Depositary or another nominee of the Depositary or to a successor
Depositary or its nominee.
 
   The laws of some jurisdictions require that certain purchasers of securities
take physical delivery of such securities in definitive form. Such laws may
impair the ability to transfer beneficial interests in a Global Security.
 
   Except as provided below, owners of beneficial interests in a Global
Security will not be entitled to receive physical delivery of Junior
Subordinated Debentures in definitive form and will not be considered the
holders (as defined in the Indenture) thereof for any purpose under the
Indenture, and no Global Security representing Junior Subordinated Debentures
shall be exchangeable, except for another Global Security of like denomination
and tenor to be registered in the name of the Depositary or its nominee or to a
successor Depositary or its nominee. Accordingly, each such beneficial owner
must rely on the procedures of the Depositary or, if such person is not a
Participant, on the procedures of the Participant through which such person
owns its interest to exercise any rights of a holder under the Indenture. If
Junior Subordinated Debentures are distributed to holders of Preferred
Securities, DTC will act as securities depositary for the Junior Subordinated
Debentures.
 
   For a description of DTC and DTC's book-entry system, see "Description of
the Preferred Securities--Book-Entry Only Issuance--The Depository Trust
Company." As of the date of this prospectus supplement, the description herein
of DTC's book-entry system and DTC's practices as they relate to purchases,
transfers, notices and payments with respect to the Preferred Securities apply
in all material respects to any debt obligations represented by one or more
Global Securities held by DTC. Reliant Energy may appoint a successor to DTC or
any successor depositary in the event DTC or such successor depositary is
unable or unwilling to continue as a depository for the Global Securities.
 
   None of Reliant Energy, the Indenture Trustee, any paying agent and any
other agent of Reliant Energy or the Indenture Trustee will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in a Global Security
for such Junior Subordinated Debentures or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.
 
   A Global Security shall be exchangeable for Junior Subordinated Debentures
registered in the names of persons other than the depositary or its nominee
only if:
 
  . the Depositary notifies Reliant Energy that it is unwilling or unable to
    continue as a depositary for such Global Security and no successor
    depositary shall have been appointed;
 
  . the Depositary, at any time, ceases to be a clearing agency registered
    under the Exchange Act at which time the Depositary is required to be so
    registered to act as such depositary and no successor depositary shall
    have been appointed; or
 
  . Reliant Energy, in its sole discretion, determines that such Global
    Security shall be so exchangeable.
 
   Any Global Security that is exchangeable pursuant to the preceding sentence
will be exchangeable for Junior Subordinated Debentures registered in such
names as the Depositary shall direct. It is expected that such instructions
will be based upon directions received by the Depositary from its Participants
with respect to ownership of beneficial interests in such Global Security.

           Relationship Between the Preferred Securities, the Junior
         Subordinated Debentures and the Preferred Securities Guarantee
 
   As set forth in the Declaration, the Trust exists for the purposes of:
 
  . issuing the Trust Securities evidencing undivided beneficial interests in
    the assets of the Trust and investing the proceeds thereof in the Junior
    Subordinated Debentures; and
 
  . engaging in only such other activities as are necessary, convenient and
    incidental thereto or are specifically authorized in the Declaration.
 
   As long as payments of interest and other payments are made when due on the
Junior Subordinated Debentures, such payments will be sufficient to cover
Distributions and other payments due on the Preferred Securities primarily
because:
 
  . the aggregate principal amount of Junior Subordinated Debentures held as
    trust assets by the Trust will be equal to the sum of the aggregate
    stated liquidation amount of the Preferred Securities and the Common
    Securities;
 
  . the interest rate and interest and other payment dates of the Junior
    Subordinated Debentures will match the Distribution rate and Distribution
    and other payment dates of the Preferred Securities;
 
  . the Declaration further provides that the Trustees will not cause or
    permit the Trust, among other things, to engage in any activity that is
    not consistent with the limited purposes of the Trust; and
 
  . the Declaration provides that Reliant Energy will pay for all debts and
    obligations (other than with respect to the Trust Securities) and all
    costs and expenses of the Trust, including the fees and expenses of the
    Trustees and any taxes and all costs and expenses with respect thereto,
    to which the Trust may become subject, except for United States
    withholding taxes. However, no assurance can be given that Reliant Energy
    will have sufficient resources to enable it to pay such debts,
    obligations, costs and expenses on behalf of the Trust.
 
   Payments of Distributions and other payments due on the Preferred Securities
are guaranteed by Reliant Energy on a subordinated basis as and to the extent
set forth under "Description of the Preferred Securities Guarantees" in the
accompanying prospectus. If Reliant Energy does not make interest or other
payments on the Junior Subordinated Debentures, the Trust will not make
Distributions or other payments on the Preferred Securities. Under the
Declaration, if and to the extent Reliant Energy does make interest or other
payments on the Junior Subordinated Debentures, the Property Trustee is
obligated to make Distributions or other payments on the Preferred Securities.
The Preferred Securities Guarantee is a full and unconditional guarantee from
the time of issuance of the Preferred Securities, but the Preferred Securities
Guarantee covers Distributions and other payments on the Preferred Securities
only if and to the extent that Reliant Energy has made a payment to the
Property Trustee of interest or principal on the Junior Subordinated
Debentures.
 
   The Property Trustee will have the power to exercise all rights, powers and
privileges under the Indenture with respect to the Junior Subordinated
Debentures, including its rights as the holder of the Junior Subordinated
Debentures to enforce Reliant Energy's obligations under the Junior
Subordinated Debentures upon the occurrence of an Indenture Event of Default,
and the Guarantee Trustee will have the right to enforce the Preferred
Securities Guarantee on behalf of the holders of the Preferred Securities. In
addition, the holders of at least a majority in liquidation amount of the
Preferred Securities will have the right to direct the Property Trustee with
respect to certain matters under the Declaration and the Preferred Securities
Guarantee. If the Property Trustee fails to enforce its rights under the
Indenture, any holder of Preferred Securities may, after a period of 30 days
has elapsed from such holder's written request to the Property Trustee to
enforce such rights, institute a legal proceeding against Reliant Energy to
enforce such rights. If the Guarantee Trustee fails to enforce the Preferred
Securities Guarantee, to the extent permitted by applicable law, any holder of
Preferred Securities may institute a legal proceeding directly against Reliant
Energy to enforce the Guarantee Trustee's
 
                                      S-32
<PAGE>
 
rights under the Preferred Securities Guarantee. Notwithstanding the foregoing,
if Reliant Energy has failed to make a Guarantee Payment, a holder of Preferred
Securities may directly institute a proceeding against Reliant Energy for
enforcement of the Preferred Securities Guarantee for such payment. See
"Description of the Preferred Securities" and "Description of the Preferred
Securities Guarantee" herein and "Description of the Preferred Securities
Guarantees--Status of the Preferred Securities Guarantee" in the accompanying
prospectus.
 
   The above mechanisms and obligations, taken together, provide a full and
unconditional guarantee by Reliant Energy of payments due on the Preferred
Securities.
 
                        Certain Federal Tax Consequences
 
   In the opinion of Baker & Botts, L.L.P., counsel to Reliant Energy and the
Trust, the following are the material United States federal income tax
consequences of the ownership and disposition of the Preferred Securities.
Unless otherwise stated, this summary deals only with the Preferred Securities
held as capital assets by holders who acquire the Preferred Securities upon
original issuance at the price indicated on the cover of this prospectus
supplement. The tax treatment of a holder may vary depending on its particular
situation. This summary does not deal with special classes of holders, such as,
for example, dealers in securities or currencies, banks, thrifts, real estate
investment trusts, regulated investment companies, life insurance companies,
persons holding Preferred Securities as part of a straddle or as part of a
hedging or conversion transaction, or persons whose functional currency is not
the United States dollar. Further, it does not include any description of
alternative minimum tax consequences or the tax laws of any state or local
government or any foreign government that may be applicable to the Preferred
Securities. This summary is based on the Internal Revenue Code of 1986, as
amended (the "Code"), Treasury Regulations thereunder and administrative and
judicial interpretations thereof as of the date hereof, all of which are
subject to change (possibly on a retroactive basis). In particular, legislation
was previously proposed by the Clinton Administration in 1996 and 1997 that, if
enacted, could have adversely affected Reliant Energy's ability to deduct
interest on the Junior Subordinated Debentures, which would in turn permit
Reliant Energy to cause a redemption of the Junior Subordinated Debentures and
therefore cause a redemption of the Preferred Securities. See "Description of
the Preferred Securities--Special Event Redemption." The authorities on which
this summary is based are subject to various interpretations, and it is
therefore possible that the federal income tax treatment of the purchase,
ownership and disposition of Preferred Securities may differ from the treatment
described below.
 
   Investors are advised to consult their tax advisors as to the United States
federal income tax consequences of the ownership and disposition of the
Preferred Securities in light of their particular circumstances, as well as the
effect of any state, local or other tax laws.
 
Classification of the Junior Subordinated Debentures
 
   Reliant Energy intends to take the position that the Junior Subordinated
Debentures will be classified for United States federal income tax purposes as
indebtedness under current law. No assurance can be given, however, that such
position of Reliant Energy will not be challenged by the IRS. The remainder of
this discussion assumes that the Junior Subordinated Debentures will be
classified for United States federal income tax purposes as indebtedness of
Reliant Energy.
 
Classification of the Trust
 
   In connection with the issuance of the Preferred Securities, Baker & Botts,
L.L.P., counsel to Reliant Energy and the Trust, will render its opinion
generally to the effect that, assuming full compliance with the terms of the
Declaration, the Trust will be classified for United States federal income tax
purposes as a grantor trust and not as an association taxable as a corporation.
Accordingly, each holder of Preferred Securities will be considered the owner
of a pro rata portion of the Junior Subordinated Debentures held by the Trust
and will be required to include in gross income its pro rata share of income
accrued on the Junior Subordinated Debentures, whether or not cash is actually
distributed to the holders.
 
                                      S-33
<PAGE>
 
Interest Income and Original Issue Discount
 
   Under Treasury Regulations issued in 1996 applicable to debt instruments
(the "Regulations"), a "remote" contingency that stated interest will not be
timely paid will be ignored in determining whether a debt instrument is issued
with original issue discount ("OID"). Reliant Energy believes that the
likelihood of its exercising its option to defer payments is remote. Based on
the foregoing, the Junior Subordinated Debentures will not be considered to be
issued with OID at the time of their original issuance and, accordingly, a
holder should include in gross income such holder's allocable share of interest
on the Junior Subordinated Debentures in accordance with such holder's method
of tax accounting.
 
   Under the Regulations, if Reliant Energy exercised its option to defer any
payment of interest, the Junior Subordinated Debentures would at that time be
treated as issued with OID, and all stated interest on the Junior Subordinated
Debentures would thereafter be treated as OID as long as the Junior
Subordinated Debentures remained outstanding. In such event, each holder of the
Preferred Securities, including a taxpayer who otherwise uses the cash method
of accounting, would be required to include its pro rata share of original
issue discount on the Junior Subordinated Debentures in income as it accrued,
in accordance with a constant yield method based on a compounding of interest,
before the receipt of cash distributions on the Preferred Securities.
Generally, during an Extension Period, all of a holder's taxable interest
income with respect to the Junior Subordinated Debentures will be accounted for
as "original issue discount" and actual distributions of stated interest will
not be separately reported as taxable income. Consequently, during an Extension
Period, a holder would be required to include OID in gross income even though
Reliant Energy would not make any actual cash payments.
 
   The Regulations have not been addressed in any rulings or other
interpretations by the Internal Revenue Service (the "IRS"), and it is possible
that the IRS could take a position contrary to the interpretation herein.
 
   No portion of the amounts received on the Preferred Securities will be
eligible for the dividends received deduction.
 
   Subsequent uses of the term "interest" in this summary include income in the
form of OID.
 
Potential Extension of Interest Payment Period on the Junior Subordinated
Debentures
 
   Holders of Preferred Securities will begin to accrue original issue discount
with respect to their pro rata share of the Junior Subordinated Debentures
during an extended interest payment period. A holder who disposes of the
Preferred Securities during an Extension Period may suffer a loss because the
market will likely fall if Reliant Energy exercises its option to defer
payments of interest on the Junior Subordinated Debentures. See "--Disposition
of the Preferred Securities" below. Furthermore, the market value of the
Preferred Securities may not reflect the accumulated Distributions that will be
paid at the end of the Extension Period, and a holder who sells the Preferred
Securities during the Extension Period will not receive from Reliant Energy any
cash related to the interest income the holder accrued and included in its
taxable income under the OID rule (because that cash will be paid to the holder
of record at the end of the Extension Period).
 
Distribution of Junior Subordinated Debentures to Holders of Preferred
Securities
 
   Under current law, a distribution by the Trust of the Junior Subordinated
Debentures as described under the caption "Description of the Preferred
Securities--Distribution of the Junior Subordinated Debentures" will be
nontaxable and will result in the holder receiving directly its pro rata share
of the Junior Subordinated Debentures previously held indirectly through the
Trust, with a holding period and tax basis equal to the holding period and
adjusted tax basis such holder was considered to have had in his pro rata share
of the underlying Junior Subordinated Debentures prior to such distribution. A
holder will include interest income in respect of Junior Subordinated
Debentures received from the Trust in the manner described above under 
"--Interest Income and Original Issue Discount."
 
                                      S-34
<PAGE>
 
Disposition of the Preferred Securities
 
   Upon a sale, exchange or other disposition of the Preferred Securities
(including a distribution of cash in redemption of a holder's Preferred
Securities upon redemption or repayment of the underlying Junior Subordinated
Debentures, but excluding the distribution of Junior Subordinated Debentures),
a holder will be considered to have disposed of all or part of its pro rata
share of the Junior Subordinated Debentures, and will recognize gain or loss
equal to the difference between the amount realized and the holder's adjusted
tax basis in its pro rata share of the underlying Junior Subordinated
Debentures deemed disposed of. Such gain or loss will be long-term capital gain
or loss if the Preferred Securities have been held by the holder for more than
one year.
 
   A holder that sells (including a redemption for cash) Preferred Securities
will recognize gain or loss equal to the difference between its adjusted tax
basis in the Preferred Securities and the amount realized on the sale of such
Preferred Securities. The amount realized is equal to the cash received, less
the amount of accrued and unpaid interest with respect to the holder's pro rata
share of the Junior Subordinated Debentures. The holder must include his share
of such accrued and unpaid interest as ordinary income. Assuming that Reliant
Energy does not exercise its option to defer payment of interest on the Junior
Subordinated Debentures, a holder's adjusted tax basis in the Preferred
Securities generally will be its initial purchase price. If the Junior
Subordinated Debentures are deemed to be issued with OID as a result of Reliant
Energy's deferral of any interest payment or otherwise, a holder's tax basis in
the Preferred Securities generally will be its initial purchase price,
increased by OID previously includible in such holder's gross income to the
date of disposition and decreased by distributions or other payments received
on the Preferred Securities since and including the date of the first Extension
Period. Such gain or loss generally will be a capital gain or loss and
generally will be a long-term capital gain or loss if the Preferred Securities
have been held for more than one year.
 
   Should Reliant Energy exercise its option to defer any payment of interest
on the Junior Subordinated Debentures, the Preferred Securities may trade at a
price that does not fully reflect the value of accrued but unpaid interest with
respect to the underlying Junior Subordinated Debentures. In the event of such
a deferral, a holder who disposes of its Preferred Securities between record
dates for payments of Distributions thereon will nevertheless be required to
include accrued but unpaid interest on the Junior Subordinated Debentures
through the date of disposition in income as OID, and to add such amount to its
adjusted tax basis in its pro rata share of the underlying Junior Subordinated
Debentures deemed disposed of. Accordingly, such a holder will recognize a
capital loss to the extent the selling price (which may not fully reflect the
value of accrued but unpaid interest) is less than the holder's adjusted tax
basis (which will include accrued but unpaid interest). Subject to certain
limited exceptions, capital losses cannot be applied to offset ordinary income
for United States federal income tax purposes.
 
Information Reporting to Holders
 
   The Trust will report the interest income paid or accrued during the year
with respect to the Junior Subordinated Debentures, and any gross proceeds
received by the Trust from the retirement or redemption of the Junior
Subordinated Debentures, annually to the holders of record of the Preferred
Securities and the IRS. The Trust currently intends to deliver such reports to
holders of record prior to January 31 following each calendar year. It is
anticipated that persons who hold Preferred Securities as nominees for
beneficial holders will report the required tax information to beneficial
holders on Form 1099.
 
Backup Withholding
 
   Payments made on, and proceeds from the sale of Preferred Securities may be
subject to a "backup" withholding tax of 31% unless the holder complies with
certain identification requirements. Any withheld amounts will generally be
allowed as a credit against the holder's federal income tax, provided the
required information is timely filed with the IRS.

United States Alien Holders
 
   For purposes of this discussion, a "United States Alien Holder" is any
corporation, individual, partnership, estate or trust that is, for U.S. federal
income tax purposes, a foreign corporation, a nonresident alien individual, a
foreign partnership or a nonresident fiduciary of a foreign estate or trust.
 
   United States Treasury Regulations were issued on October 14, 1997 (the
"Withholding Regulations") that affect the procedures to be followed by a
United States Alien Holder in establishing its non-U.S. person status. The
Withholding Regulations are generally effective with respect to payments made
after December 31, 1999, subject to certain transition rules. The discussion
below is not intended to be a complete discussion of the provisions of the
Withholding Regulations, and prospective investors are urged to consult their
tax advisors with respect to the effect of the Withholding Regulations.
 
   Reliant Energy will not pay any additional amounts on the Junior
Subordinated Debentures held by a United States Alien Holder in respect of any
tax, assessment or governmental charge withheld or deducted.
 
   Payments on the Preferred Securities. As discussed above, Reliant Energy
intends to take the position that the Junior Subordinated Debentures will be
classified for U.S. federal income tax purposes as indebtedness of Reliant
Energy under current law; no assurance can be given, however, that such
position of Reliant Energy will not be challenged by the IRS.
 
   Assuming that the Junior Subordinated Debentures are classified for U.S.
federal income tax purposes as indebtedness of Reliant Energy, under present
U.S. federal income tax law, payments by the Trust or any of its paying agents
to any holder of Preferred Securities who or which is a United States Alien
Holder would not be subject to U.S. federal withholding tax, provided, that (a)
the beneficial owner of the Preferred Securities does not actually or
constructively own 10% or more of the total combined voting power of all
classes of stock of Reliant Energy entitled to vote, (b) the beneficial owner
of the Preferred Securities is not a controlled foreign corporation that is
related to Reliant Energy through stock ownership, and (c) either (A) the
beneficial owner of the Preferred Securities certifies to the Trust or its
agent, under penalties of perjury, that it is not a U.S. person and provides
its name and address or (B)(x) a securities clearing organization, bank or
other financial institution that holds customers' securities in the ordinary
course of its trade or business (a "Financial Institution"), and holds the
Preferred Securities in such capacity, certifies to the Trust or its agent,
under penalties of perjury, that such statement has been received from the
beneficial owner by it or by a Financial Institution between it and the
beneficial owner and furnishes the Trust or its agent with a copy thereof or
(y) with respect to payments after December 31, 1999, a "qualified
intermediary" (which includes certain foreign financial institutions, foreign
clearing organizations or foreign branches of United States financial
institutions or clearing organizations which have entered into withholding
agreements with the IRS and have received appropriate certification from the
beneficial owner) provides the Trust or any of its paying agents with an
intermediary withholding certificate.
 
   If the Junior Subordinated Debentures were not classified for U.S. federal
income tax purposes as indebtedness of Reliant Energy, payments by the Trust or
any of its paying agents to any holder of Preferred Securities who or which is
a United States Alien Holder would be subject to U.S. withholding tax at a 30%
rate (or a lower rate prescribed by an applicable tax treaty). Prospective
investors that would be United States Alien Holders should consult their tax
advisors concerning the possible application of these rules.
 
   Sale or Exchange of Preferred Securities. A United States Alien Holder
(other than certain U.S. expatriates) generally would not be subject to U.S.
federal income tax on gain realized on the sale, exchange or other disposition
of the Preferred Securities unless the United States Alien Holder is an
individual who is present in the U.S. for 183 days or more in the taxable year
of disposition, and certain other conditions are satisfied.
 
   Effectively Connected Income. If a United States Alien Holder of Preferred
Securities is engaged in a trade or business in the United States, and if the
interest income paid or accrued on the Preferred Securities is
 
                                      S-36
<PAGE>
 
effectively connected with the conduct of such trade or business, the United
States Alien Holder, although exempt from the withholding tax on distributions
on Preferred Securities, will generally be subject to regular United States
income tax on the interest income and on any gain realized on the sale,
exchange or other disposition of Preferred Securities in the same manner as if
it were a United States person. Such a holder will be required to provide to
the applicable withholding agent a properly executed IRS Form 4224 in order to
claim an exemption from withholding tax. In addition, if such United States
Alien Holder is a foreign corporation, it may be subject to a branch profits
tax equal to 30% (or a lower rate prescribed by an applicable treaty) of its
effectively connected earnings and profits for the taxable year.

</TABLE>
 
   The underwriters are obligated to purchase all of the Preferred Securities,
if any Preferred Securities are purchased.
 
   Reliant Energy and the Trust have agreed with the underwriters to indemnify
them against certain civil liabilities, including liabilities under the
Securities Act of 1933, or to contribute with respect to payments which the
underwriters may be required to make.
 
   The underwriters have in the past and may in the future engage in
transactions with, or perform services for, Reliant Energy or its subsidiaries
in the ordinary course of their businesses.
 
   Reliant Energy will pay all expenses, estimated to be approximately $
million, associated with the offer and the sale of the Preferred Securities.
 
Commission and Discounts
 
   The underwriters will offer the Preferred Securities directly to the public
at a price of $25 per Preferred Security. The underwriters may also offer the
Preferred Securities to certain dealers at the above mentioned offering price
less a concession of $    per Preferred Security. The underwriters may allow,
and such dealers may reallow, a discount not in excess of $    per Preferred
Security to certain dealers. After the initial public offering, the public
offering price, concession and discount may be changed.

   Because the proceeds from the sale of the Preferred Securities will be used
to purchase the Junior Subordinated Debentures, Reliant Energy has agreed to
pay to the underwriters an underwriting commission of $     per Preferred
Security (or a total of $              ). However, the underwriting commission
for sales of 10,000 or more Preferred Securities to a single purchaser will be
$.   per Preferred Security. If any such sales occur, the total amount of the
underwriting commission will be less than $     million.

and total underwriting commission to be paid by Reliant Energy to the
underwriters and proceeds to the Trust.

New York Stock Exchange Listing
 
   Before this offering, there has been no established public trading market
for the Preferred Securities. The Trust intends to apply to list the Preferred
Securities on the New York Stock Exchange. If approved for listing, Reliant
Energy expects trading of the Preferred Securities to begin within 30 days of
the issuance of the Preferred Securities. In order to meet all of the
requirements for listing the Preferred Securities on the New York Stock
Exchange, the underwriters have agreed to sell the Preferred Securities to a
minimum of 400 beneficial holders. The representatives have advised Reliant
Energy that they intend to make a market in the Preferred Securities prior to
the commencement of trading on the New York Stock Exchange. However, the
representatives are not obligated to do so and may discontinue market making at
any time without notice. No assurances can be given about the liquidity of the
trading market for the Preferred Securities.
 
No Sales of Similar Securities
 
   Reliant Energy and the Trust have agreed that, during the period beginning
on the date of the underwriting agreement and continuing to and including the
date of delivery of the Preferred Securities to the underwriters in accordance
with the underwriting agreement, they will not offer, sell, contract to sell or
otherwise dispose of any Preferred Securities, any securities convertible into
or exchangeable into or exercisable for the Preferred Securities or the Junior
Subordinated Debentures or any debt securities substantially similar to the
Junior Subordinated Debentures or any equity securities substantially similar
to the Preferred Securities (except for the Junior Subordinated Debentures and
the Preferred Securities issued pursuant to the underwriting agreement) without
the prior written consent of Merrill Lynch, Pierce, Fenner & Smith
Incorporated.
 
Price Stabilization and Short Positions
 
   In connection with the sale of the Preferred Securities, Securities and
Exchange Commission rules permit the underwriters to engage in transactions
that stabilize the price of the Preferred Securities. These transactions may
include purchases for the purpose of fixing or maintaining the price of the
Preferred Securities.
 
   The underwriters may create a short position in the Preferred Securities in
connection with the offering. That means that they sell a larger number of the
Preferred Securities than is shown on the cover page of this prospectus
supplement. If they create a short position, the underwriters may purchase
Preferred Securities in the open market to reduce the short position.
 
   If the underwriters purchase the Preferred Securities to stabilize the price
or to reduce their short position, the price of the Preferred Securities could
be higher than it might be if they had not made such purchases. The
underwriters make no representation or prediction about any effect that the
purchases may have on the price of the Preferred Securities.
 
   The underwriters may suspend any of these activities at any time.

Penalty Bids
 
   The representatives also may impose a penalty bid on certain underwriters
and selling group members. This means that, if the representatives purchased
Preferred Securities in the open market to reduce the underwriters' short
position or to stabilize the price of the Preferred Securities, they may
reclaim the amount of the selling concession from the underwriters and selling
group members who sold those Preferred Securities as part of this offering.

                             ABOUT THIS PROSPECTUS
 
   This prospectus is part of a registration statement that we have filed with
the Securities and Exchange Commission (the "Commission") using a "shelf"
registration process. By using this process, we may offer the securities
described in this prospectus in one or more public offerings with a total
aggregate initial offering price of up to $500,000,000. This prospectus
provides you with a general description of the securities we may offer. Each
time we offer securities, we will provide a prospectus supplement. The
prospectus supplement will describe the specific terms of the offering. The
prospectus supplement may also add, update or change the information contained
in this prospectus. Please carefully read this prospectus and the applicable
prospectus supplement, in addition to the information contained in the
documents we refer to under the heading "Where You Can Find More Information."
 
   You should rely only on the information contained or incorporated by
reference in this prospectus and any accompanying prospectus supplement. We
have not authorized anyone else to provide you with any different information.
If anyone provides you with different or inconsistent information, you should
not rely on it. We are not making an offer to sell these securities in any
jurisdiction where the offer or sale is not permitted. The information
contained in this prospectus is current only as of the date of this prospectus.
 
   We have not included separate financial statements of the Trusts in this
prospectus. We do not consider that such financial statements would be material
to holders of the Trusts' trust preferred securities because:
 
  . Each Trust is a newly created special purpose entity;
 
  . Each Trust has no operating history or independent operations; and
 
  . Neither Trust is engaged in nor does it propose to engage in any activity
    other than holding the Junior Subordinated Debt Securities (as defined
    herein), issuing the Trust Securities (as defined herein) and any other
    activity related thereto or specifically authorized by the Trust's
    Declaration (as defined herein).
 
   Furthermore, taken together, the Company's obligations under the Junior
Subordinated Debt Securities, the Indenture, the Declarations and the Preferred
Securities Guarantees (each, as defined herein) provide, in the aggregate, a
full, irrevocable and unconditional guarantee of payments of distributions and
other amounts due on the Trusts' preferred securities. See "The Trusts,"
"Description of the Preferred Securities," "Description of the Preferred
Securities Guarantees" and "Description of the Junior Subordinated Debt
Securities." In addition, we do not expect that the Trusts will file reports
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
with the Commission.

                DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS
 
   Statements contained in this prospectus and any accompanying prospectus
supplement, including the documents that are incorporated by reference as set
forth in "Where You Can Find More Information," that are not historical facts
are forward-looking statements as defined in the Private Securities Litigation
Reform Act of 1995. Forward-looking statements are based on the beliefs of the
Company's management as well as assumptions made by and information currently
available to management. The Company and the Trusts caution that assumptions,
projections, expectations, intentions or beliefs about future events may and
often do vary materially from actual results and the differences between
assumptions, projections, expectations, intentions or beliefs and actual
results can be material. Accordingly, there can be no assurance actual results
will not differ materially from those expressed or implied by forward-looking
statements.
 
   The following are some of the factors that could cause actual results to
differ from those expressed or implied in the forward-looking statements
contained herein:
 
  . state and federal legislative and regulatory initiatives that affect cost
    and investment recovery, have an impact on rate restructuring and affect
    the speed and degree to which competition enters the electric and natural
    gas industries;
 
  . industrial, commercial and residential growth in our service territories;
 
  . the weather and other natural phenomena;
 
  . the timing and extent of changes in commodity prices and interest rates;
 
  . changes in environmental and other laws and regulations to which the
    Company and its subsidiaries are subject or other external factors over
    which the Company has no control;
 
  . the results of financing efforts;
 
  . growth in opportunities for the Company's subsidiaries and diversified
    operations;
 
  . risks incidental to the Company's overseas operations (including the
    effects of fluctuations in foreign currency exchange rates);
 
  . the effect of the Company's accounting policies; and
 
  . other factors discussed in this and other filings by the Company with the
    Commission.
 
   When used in the Company's documents, the words "anticipate," "estimate,"
"expect," "forecast," "goal," "objective," "projection" or similar words are
intended to identify forward-looking statements.

(1) The Company believes that the ratios for the nine-month periods are not
    necessarily indicative of the ratios for the twelve-month periods due to
    the seasonal nature of the Company's business and adjustments to the
    Company's financial statements resulting from its acquisition of NorAm on
    August 6, 1997.
(2) Includes the results of NorAm from the date of its acquisition which was
    accounted for under the purchase method.
 
                                USE OF PROCEEDS
 
   Unless otherwise indicated in the applicable prospectus supplement, the
Company anticipates that any net proceeds from the sale of the securities
offered hereby will be used for general corporate purposes, which may include,
but are not limited to, working capital, capital expenditures, acquisitions and
the repayment or refinancing of the Company's indebtedness, including inter-
company indebtedness.
 
   Each Trust will use all proceeds received from the sale of its Trust
Securities to purchase Junior Subordinated Debt Securities from the Company.
 
                                   THE TRUSTS
 
   HI Trust I and HI Trust II (each a "Trust", and collectively the "Trusts")
are statutory business trusts created on January 11, 1999, under the Delaware
Business Trust Act (the "Business Trust Act") pursuant to separate declarations
of trust among the Trustees (as defined herein) of each Trust and the Company
and the filing of a certificate of trust with the Secretary of State of the
State of Delaware. Each such declaration will be amended and restated in its
entirety (as so amended and restated, the "Declaration" and together, the
"Declarations") as of the date the respective Trust initially issues trust
preferred securities representing preferred undivided beneficial interests in
the assets of such Trust (the "Preferred Securities"). Each Declaration will be
qualified under the Trust Indenture Act of 1939, as amended (the "Trust
Indenture Act").
 
   The following description summarizes the material terms of the Declarations
and is qualified in its entirety by reference to the form of Declaration, which
has been filed as an exhibit to the registration statement of which this
prospectus is a part, and the Trust Indenture Act.
 
   The address of the principal office of each Trust is c/o Houston Industries
Incorporated, 1111 Louisiana, Houston, Texas 77002, and the telephone number of
each Trust at such address is (713) 207-3000.
 
Preferred Securities
 
   Upon issuance of any Preferred Securities by a Trust, the holders thereof
will own all of the issued and outstanding Preferred Securities of such Trust.
The Company will, directly or indirectly, acquire common securities
representing common undivided beneficial interests in the assets of each Trust
(the "Common
 
                                       5
<PAGE>
 
Securities" and, together with the Preferred Securities, the "Trust
Securities") in an amount equal to 3% of the total capital of such Trust and
will own, directly or indirectly, all of the issued and outstanding Common
Securities of each Trust. The Preferred Securities and the Common Securities
will rank pari passu with each other and will have equivalent terms; provided
that (i) if a Declaration Event of Default (as defined under "--Events of
Default") under the Declaration of a Trust occurs and is continuing, the
holders of Preferred Securities of such Trust will have a priority over holders
of the Common Securities of such Trust with respect to payments in respect of
distributions and payments upon liquidation, redemption and maturity and (ii)
the holders of Common Securities have the exclusive right to appoint, remove or
replace the Trustees and to increase or decrease the number of Trustees. Each
Trust exists for the purposes of (a) issuing its Preferred Securities, (b)
issuing its Common Securities to the Company, (c) investing the gross proceeds
from the sale of its Trust Securities in Junior Subordinated Debt Securities of
the Company and (d) engaging in only such other activities as are necessary,
convenient or incidental thereto or are specifically authorized in its
Declaration. The rights of the holders of the Preferred Securities of a Trust,
including economic rights, rights to information and voting rights, are set
forth in the applicable Declaration, the Business Trust Act and the Trust
Indenture Act.
 
Powers and Duties of Trustees
 
   The number of trustees (the "Trustees") of each Trust will initially be
five. Three of the Trustees (the "Regular Trustees") are individuals who are
officers, directors or employees of the Company. The fourth Trustee is The Bank
of New York, which is unaffiliated with the Company and serves as the property
trustee (the "Property Trustee") and acts as the indenture trustee under the
Declaration for purposes of the Trust Indenture Act. The fifth Trustee is The
Bank of New York (Delaware) which has its principal place of business in the
State of Delaware (the "Delaware Trustee"). Pursuant to each Declaration, legal
title to the Junior Subordinated Debt Securities purchased by a Trust will be
owned by and held of record in the name of the Property Trustee in trust for
the benefit of the holders of the Trust Securities of such Trust, and the
Property Trustee will have the legal power to exercise all rights, powers and
privileges under the Indenture (as defined under "Description of the Junior
Subordinated Debt Securities") with respect to such Junior Subordinated Debt
Securities. In addition, the Property Trustee will maintain exclusive control
of a segregated non-interest bearing bank account (the "Property Account") to
hold all payments in respect of the Junior Subordinated Debt Securities
purchased by a Trust for the benefit of the holders of its Trust Securities.
The Property Trustee will promptly make distributions to the holders of the
Trust Securities out of funds from the Property Account. The Preferred
Securities Guarantees are separately qualified under the Trust Indenture Act
and will be held by The Bank of New York (the "Guarantee Trustee"), acting in
its capacity as indenture trustee with respect thereto, for the benefit of the
holders of the applicable Preferred Securities. As used in this prospectus and
any accompanying prospectus supplement, the term "Property Trustee" with
respect to a Trust refers to The Bank of New York acting either in its capacity
as a Trustee under the related Declaration and the holder of legal title to the
Junior Subordinated Debt Securities purchased by such Trust or in its capacity
as the Guarantee Trustee under the applicable Preferred Securities Guarantee,
as the context may require. The Company, as the direct or indirect owner of all
of the Common Securities of each Trust, will have the exclusive right to
appoint, remove or replace Trustees and to increase or decrease the number of
Trustees, provided that the number of Trustees will be, except under certain
circumstances, at least five and the majority of Trustees will be Regular
Trustees. The term of a Trust will be set forth in the applicable prospectus
supplement but may dissolve earlier as provided in the applicable Declaration.
 
   The duties and obligations of the Trustees of a Trust will be governed by
the Declaration of such Trust, the Business Trust Act and the Trust Indenture
Act. Under its Declaration, each Trust will not, and the Trustees will cause
such Trust not to, engage in any activity other than in connection with the
purposes of such Trust or other than as required or authorized by the related
Declaration. In particular, each Trust will not and the Trustees will cause
each Trust not to (a) invest any proceeds received by such Trust from holding
the Junior Subordinated Debt Securities purchased by such Trust but shall
promptly distribute from the Property Account all such proceeds to holders of
its Trust Securities pursuant to the terms of the related Declaration and of
its
 
                                       6
<PAGE>
 
Trust Securities; (b) acquire any assets other than as expressly provided in
the related Declaration; (c) possess property of such Trust for other than a
Trust purpose; (d) make any loans, other than loans represented by the Junior
Subordinated Debt Securities; (e) possess any power or otherwise act in such a
way as to vary the assets of such Trust or the terms of its Trust Securities in
any way whatsoever, except as expressly provided in the related Declaration;
(f) issue any securities or other evidences of beneficial ownership of, or
beneficial interests in, such Trust other than its Trust Securities; (g) incur
any indebtedness for borrowed money; (h) direct the time, method and place of
conducting any proceeding for any remedy available to the Indenture Trustee (as
defined under "Description of the Junior Subordinated Debt Securities") or
exercising any trust or power conferred upon the Indenture Trustee with respect
to the Junior Subordinated Debt Securities deposited in such Trust as trust
assets; (i) waive any past default that is waivable under the Indenture; (j)
exercise any right to rescind or annul a declaration of acceleration of the
maturity of the principal of all of the Junior Subordinated Debt Securities
deposited in such Trust as trust assets, without, in the case of clauses (h),
(i) and (j), obtaining the prior approval of the holders of a majority in
liquidation amount of all outstanding Trust Securities of such Trust; (k)
consent to any amendment, modification or termination of the Indenture or the
Junior Subordinated Debt Securities deposited in such Trust as trust assets,
where such consent is required, unless in the case of this clause (k) the
Property Trustee shall have received an opinion of counsel experienced in such
matters to the effect that such amendment, modification or termination will not
cause more than an insubstantial risk that for United States federal income tax
purposes such Trust will not be classified as a grantor trust; (l) take or
consent to any action that would result in the placement of a lien, pledge,
charge, mortgage or other encumbrance on any of the property of such Trust; (m)
vary the investment (within the meaning of Treasury Regulation Section
301.7701-4(c)) of such Trust or of the holders of its Trust Securities; (n)
after the issuance of its Preferred Securities, enter into any contract or
agreement (other than any depositary agreement or any agreement with any
securities exchange or automated quotation system) that does not expressly
provide that the holders of such Preferred Securities, in their capacities as
such, have limited liability (in accordance with the provisions of the Business
Trust Act) for the liabilities and obligations of such Trust or (o) revoke any
action previously authorized or approved by a vote of the holders of its
Preferred Securities except by subsequent vote of such holders.
 
Books and Records
 
   The books and records of each Trust will be maintained at the principal
office of such Trust and will be open for inspection by a holder of Preferred
Securities of such Trust or his authorized representative for any purpose
reasonably related to his interest in such Trust during normal business hours.
 
Voting
 
   Holders of Preferred Securities generally will have limited voting rights,
relating only to the modification of the Preferred Securities and, under
certain circumstances, to the exercise of a Trust's rights as holder of the
Junior Subordinated Debt Securities and the Preferred Securities Guarantee. The
holders of the Preferred Securities will not be able to appoint, remove or
replace, or to increase or decrease the number of, Trustees, which rights are
vested exclusively in the holders of the Common Securities.
 
The Property Trustee
 
   The Property Trustee, for the benefit of the holders of the Trust Securities
of a Trust, is authorized under each Declaration to exercise all rights under
the Indenture with respect to the Junior Subordinated Debt Securities deposited
in such Trust as trust assets, including its rights as the holder of such
Junior Subordinated Debt Securities to enforce the Company's obligations under
such Junior Subordinated Debt Securities upon the occurrence of an Indenture
Event of Default (as defined herein under "Description of the Junior
Subordinated Debt Securities--Indenture Events of Default"). The Property
Trustee will also be authorized to enforce the rights of holders of the
Preferred Securities of a Trust under the related Preferred Securities
Guarantee. If any Trust's failure to make distributions on the Preferred
Securities of such Trust is a consequence of the Company's exercise of any
right under the terms of the Junior Subordinated Debt Securities deposited in
such
 
                                       7
<PAGE>
 
Trust as trust assets to extend the interest payment period for such Junior
Subordinated Debt Securities, the Property Trustee will have no right to
enforce the payment of distributions on such Preferred Securities until a
Declaration Event of Default shall have occurred. If a Declaration Event of
Default has occurred and is continuing, then the holders of at least a majority
in liquidation amount of the Preferred Securities of a Trust will have the
right to direct the Property Trustee for such Trust with respect to certain
matters under the related Declaration and the related Preferred Securities
Guarantee. If the Property Trustee fails to enforce its rights under the
applicable series of Junior Subordinated Debt Securities, any holder of
Preferred Securities, to the extent permitted by applicable law, may, after a
period of 30 days has elapsed from such Holder's written request to the
Property Trustee to enforce such rights, institute a legal proceeding directly
against the Company to enforce such rights without first instituting any legal
proceeding against the Property Trustee or any other person. Notwithstanding
the foregoing, if a Declaration Event of Default under the applicable
Declaration has occurred and is continuing and such event is attributable to
the failure of the Company to pay interest or principal, or premium, if any, on
the applicable series of Junior Subordinated Debt Securities on the date such
interest, principal or premium is otherwise payable (or in the case of
redemption, on the redemption date), then a holder of Preferred Securities of
such Trust may directly institute a proceeding for enforcement of payment to
such holder of the principal of, or premium, if any, or interest on the
applicable series of Junior Subordinated Debt Securities having a principal
amount equal to the aggregate liquidation amount of the Preferred Securities of
such holder (a "Holder Direct Action") on or after the respective due date
specified in the applicable series of Junior Subordinated Debt Securities. In
connection with such Holder Direct Action, the Company will be subrogated to
the rights of such holder of Preferred Securities under the applicable
Declaration to the extent of any payment made by the Company to such holder of
Preferred Securities in such Holder Direct Action. Except as expressly provided
in the preceding sentences or in the applicable prospectus supplement, the
holders of Preferred Securities of such Trust will not be able to exercise
directly any other remedy available to the holders of the applicable series of
Junior Subordinated Debt Securities.
 
Distributions
 
   Pursuant to each Declaration, distributions on the Preferred Securities of a
Trust must be paid on the dates payable to the extent that the Property Trustee
for such Trust has cash on hand in the applicable Property Account to permit
such payment. The funds available for distribution to the holders of the
Preferred Securities of a Trust will be limited to payments received by the
Property Trustee in respect of the Junior Subordinated Debt Securities that are
deposited in such Trust as trust assets. If the Company does not make interest
payments on the Junior Subordinated Debt Securities deposited in a Trust as
trust assets, the Property Trustee will not make distributions on the Preferred
Securities of such Trust. Under each Declaration, if and to the extent the
Company does make interest payments on the Junior Subordinated Debt Securities
deposited in a Trust as trust assets, the Property Trustee is obligated to make
distributions on the Trust Securities of such Trust on a Pro Rata Basis (as
defined below). The payment of distributions on the Preferred Securities of a
Trust is guaranteed by the Company as and to the extent set forth under
"Description of the Preferred Securities Guarantees." A Preferred Securities
Guarantee is a guarantee from the time of issuance of the Preferred Securities,
but the Preferred Securities Guarantee covers distributions and other payments
on the applicable Preferred Securities only if and to the extent that the
Company has made a payment to the Property Trustee of interest or principal, or
premium, if any, on the Junior Subordinated Debt Securities deposited in a
Trust as trust assets. As used in this prospectus, the term "Pro Rata Basis"
shall mean pro rata to each holder of Trust Securities of a Trust according to
the aggregate liquidation amount of the Trust Securities of such Trust held by
the relevant holder in relation to the aggregate liquidation amount of all
Trust Securities of such Trust outstanding unless, in relation to a payment, a
Declaration Event of Default under the related Declaration has occurred and is
continuing, in which case any funds available to make such payment shall be
paid first to each holder of the Preferred Securities of such Trust pro rata
according to the aggregate liquidation amount of the Preferred Securities held
by the relevant holder in relation to the aggregate liquidation amount of all
the Preferred Securities of such Trust outstanding, and only after satisfaction
of all amounts owed to the holders of such Preferred Securities, to each holder
of Common Securities of such Trust pro rata according to the aggregate
liquidation amount of such Common Securities held by the relevant holder in
relation to the aggregate liquidation amount of all Common Securities of such
Trust outstanding.

Events of Default
 
   If an Indenture Event of Default occurs and is continuing with respect to
the Junior Subordinated Debt Securities deposited in a Trust as trust assets,
an Event of Default under the Declaration (a "Declaration Event of Default") of
such Trust will occur and be continuing, with respect to any outstanding Trust
Securities of such Trust. In such event, each Declaration provides that the
holders of Common Securities of such Trust will be deemed to have waived any
such Declaration Event of Default with respect to the Common Securities until
all Declaration Events of Default with respect to the Preferred Securities of
such Trust have been cured or waived or otherwise eliminated. Until all such
Declaration Events of Default with respect to the Preferred Securities of such
Trust have been so cured, waived or otherwise eliminated, the Property Trustee
will be deemed to be acting solely on behalf of the holders of the Preferred
Securities of such Trust and only the holders of such Preferred Securities will
have the right to direct the Property Trustee with respect to certain matters
under such Declaration and consequently under the Indenture. In the event that
any Declaration Event of Default with respect to the Preferred Securities of
such Trust is waived by the holders of the Preferred Securities of such Trust
as provided in the Declaration, the holders of Common Securities of such Trust
pursuant to such Declaration have agreed that such waiver also constitutes a
waiver of such Declaration Event of Default with respect to such Common
Securities for all purposes under the Declaration without any further act, vote
or consent of the holders of such Common Securities. The Property Trustee shall
notify each holder of Preferred Securities of a Trust of any notice of default
with respect to the related Junior Subordinated Debt Securities, unless such
default has been cured before the giving of such notice or the board of
directors, the executive committee or a trust committee of directors and/or
Responsible Officers (as that term is defined in the applicable Declaration) of
the Property Trustee in good faith determines that the withholding of such
notice is in the interests of the holders of the Trust Securities of such
Trust.
 
Record Holders
 
   Each Declaration provides that the Trustees of such Trust may treat the
person in whose name a certificate representing its Preferred Securities is
registered on the books and records of such Trust as the sole holder thereof
and of the Preferred Securities represented thereby for purposes of receiving
distributions and for all other purposes and, accordingly, will not be bound to
recognize any equitable or other claim to or interest in such certificate or in
the Preferred Securities represented thereby on the part of any person, whether
or not the Trustees of such Trust shall have actual or other notice thereof.
Preferred Securities will be issued in fully registered form. Unless otherwise
specified in a prospectus supplement, Preferred Securities will be represented
by one or more global certificates registered on the books and records of such
Trust in the name of a depositary (the "Depositary") named in an accompanying
prospectus supplement or its nominee. Under each Declaration:
 
     (i) such Trust and the Trustees thereof will be entitled to deal with
  the Depositary (or any successor depositary) for all purposes, including
  the payment of distributions and receiving approvals, votes or consents
  under the related Declaration, and except as set forth in the related
  Declaration with respect to the issuance of definitive certificates
  representing the Preferred Securities, will have no obligation to persons
  owning a beneficial interest in Preferred Securities ("Preferred Security
  Beneficial Owners") registered in the name of and held by the Depositary or
  its nominee; and
 
     (ii) the rights of Preferred Security Beneficial Owners will be
  exercised only through the Depositary (or any successor depositary) and
  will be limited to those established by law and agreements between such
  Preferred Security Beneficial Owners and the Depositary and/or its
  participants. With respect to Preferred Securities registered in the name
  of and held by the Depositary or its nominee, all notices and other
  communications required under each Declaration will be given to, and all
  distributions on such Preferred Securities will be given or made to, the
  Depositary (or its successor).
 
   The specific terms of the depositary arrangement with respect to the
Preferred Securities of a Trust will be disclosed in the applicable prospectus
supplement.

Debts and Obligations
 
   In each Declaration, the Company has agreed to pay all debts and obligations
(other than with respect to the related Trust Securities) and all costs and
expenses of the applicable Trust, including the fees and expenses of its
Trustees and any taxes and all costs and expenses with respect thereto, to
which such Trust may become subject, except for United States withholding
taxes. The foregoing obligations of the Company under each Declaration are for
the benefit of, and will be enforceable by, any person to whom any such debts,
obligations, costs, expenses and taxes are owed (a "Creditor") whether or not
such Creditor has received notice thereof. Any such Creditor may enforce such
obligations of the Company directly against the Company, and the Company has
irrevocably waived any right or remedy to require that any such Creditor take
any action against any Trust or any other person before proceeding against the
Company. The Company will be subrogated to all rights of a Trust in respect of
any amounts paid to any Creditor by the Company. The Company has agreed in each
Declaration to execute such additional agreements as may be necessary or
desirable in order to give full effect to the foregoing.
 
                    DESCRIPTION OF THE PREFERRED SECURITIES
 
   Each Trust may issue, from time to time, only one series of Preferred
Securities having terms described in the prospectus supplement relating
thereto. The Declaration of each Trust authorizes the Regular Trustees of such
Trust to issue on behalf of such Trust one series of Preferred Securities. Each
Declaration will be qualified as an indenture under the Trust Indenture Act.
The Preferred Securities will have such terms, including distributions,
redemption, voting, liquidation rights and such other preferred, deferred or
other special rights or such restrictions as set forth in the related
Declaration or made part of such Declaration by the Trust Indenture Act.
Reference is made to the prospectus supplement relating to the Preferred
Securities of a Trust for specific terms, including (i) the specific
designation of such Preferred Securities, (ii) the number of Preferred
Securities issued by such Trust, (iii) the annual distribution rate (or method
of calculation thereof) for Preferred Securities issued by such Trust, the date
or dates upon which such distributions will be payable and the record date or
dates for the payment of such distributions, (iv) whether distributions on the
Preferred Securities issued by such Trust will be cumulative, and, in the case
of Preferred Securities having such cumulative distribution rights, the date or
dates or method of determining the date or dates from which distributions on
Preferred Securities issued by such Trust will be cumulative, (v) the amount or
amounts which will be paid out of the assets of such Trust to the holders of
Preferred Securities of such Trust upon voluntary or involuntary dissolution,
winding-up or termination of such Trust, (vi) the obligation or right, if any,
of such Trust to purchase or redeem Preferred Securities issued by such Trust
and the price or prices at which, the period or periods within which and the
terms and conditions upon which Preferred Securities issued by such Trust will
or may be purchased or redeemed, in whole or in part, pursuant to such
obligation or right, (vii) the voting rights, if any, of Preferred Securities
issued by such Trust in addition to those required by law, including the number
of votes per Preferred Security and any requirement for the approval by the
holders of Preferred Securities, as a condition to specified actions or
amendments to the Declaration of such Trust, (viii) terms for any conversion or
exchange into other securities (ix) the rights, if any, to defer distributions
on the Preferred Securities by extending the interest payment period on the
Junior Subordinated Debt Securities and (x) any other relevant, terms, rights,
preferences, privileges, limitations or restrictions of Preferred Securities
issued by such Trust consistent with the Declaration of such Trust or with
applicable law. All Preferred Securities offered hereby will be guaranteed by
the Company as and to the extent set forth below under "Description of the
Preferred Securities Guarantees." Certain United States federal income tax
considerations applicable to any offering of Preferred Securities will be
described in the prospectus supplement relating thereto.
 
   In connection with the issuance of the Preferred Securities, each Trust will
issue one series of Common Securities. The Declaration of each Trust authorizes
the Regular Trustees of such Trust to issue on behalf of such Trust one series
of Common Securities having such terms including distributions, redemption,
voting, liquidation rights or such restrictions as set forth therein. The terms
of the Common Securities issued by a Trust
 
                                       10
<PAGE>
 
will be substantially identical to the terms of the Preferred Securities issued
by such Trust and the Common Securities will rank pari passu, and payments will
be made thereon on a Pro Rata Basis with the Preferred Securities except that
if a Declaration Event of Default occurs and is continuing, the rights of the
holders of such Common Securities to payment in respect of distributions and
payments upon liquidation, redemption and maturity will be subordinated to the
rights of the holders of such Preferred Securities. The Common Securities
issued by a Trust will also carry the right to vote and to appoint, remove or
replace any of the Trustees of such Trust. All of the Common Securities issued
by a Trust will be directly or indirectly owned by the Company.
 
               DESCRIPTION OF THE PREFERRED SECURITIES GUARANTEES
 
   The payment of periodic cash distributions with respect to the Preferred
Securities of each Trust out of moneys held by the Property Trustee of each
Trust, and payments on liquidation of each Trust and redemption of Preferred
Securities of each Trust, will be fully and unconditionally guaranteed by the
Company as described herein (each such guarantee, a "Preferred Securities
Guarantee"). Set forth below is a summary of the Preferred Securities
Guarantees that will be executed and delivered by the Company for the benefit
of the holders from time to time of Preferred Securities. Each Preferred
Securities Guarantee will be separately qualified under the Trust Indenture Act
and will be held by The Bank of New York, acting in its capacity as indenture
trustee with respect thereto (the "Guarantee Trustee"), for the benefit of
holders of the Preferred Securities of the applicable Trust. The terms of each
Preferred Securities Guarantee will be those set forth in such Preferred
Securities Guarantee and those made part of such Guarantee by the Trust
Indenture Act. This description summarizes the material terms of the Preferred
Securities Guarantees and is qualified in its entirety by reference to the form
of Preferred Securities Guarantee, which is filed as an exhibit to the
registration statement of which this prospectus forms a part, and the Trust
Indenture Act.
 
General
 
   Pursuant to each Preferred Securities Guarantee, the Company will
irrevocably and unconditionally agree, to the extent set forth therein, to pay
in full, to the holders of the Preferred Securities issued by a Trust, the
Guarantee Payments (as defined herein) (without duplication of amounts
theretofore paid by such Trust), as and when due, regardless of any defense,
right of set-off or counterclaim that such Trust may have or assert. The
following payments or distributions with respect to Preferred Securities issued
by a Trust to the extent not paid or made by or on behalf of such Trust will be
subject to such Preferred Securities Guarantee (without duplication): (i) any
accumulated and unpaid distributions on such Preferred Securities, and the
redemption price, including all accumulated and unpaid distributions to, but
excluding, the date of redemption, with respect to such Preferred Securities
called for redemption by such Trust but if and only to the extent that in each
case the Company has made a payment to the related Property Trustee of interest
or principal, or premium, if any, on the Junior Subordinated Debt Securities
deposited in such Trust as trust assets and (ii) upon a voluntary or
involuntary dissolution, winding-up or termination of such Trust (other than in
connection with the distribution of Junior Subordinated Debt Securities to the
holders of such Preferred Securities in exchange for Preferred Securities or
the redemption of all of such Preferred Securities upon the maturity or
redemption of the Junior Subordinated Debt Securities), the lesser of (a) the
aggregate of the liquidation amount and all accumulated and unpaid
distributions on such Preferred Securities to the date of payment, to the
extent such Trust has funds on hand legally available therefor, and (b) the
amount of assets of such Trust remaining available for distribution to holders
of such Preferred Securities in liquidation of such Trust as required by
applicable law (the "Guarantee Payments"). The Company's obligation to make a
Guarantee Payment may be satisfied by direct payment of the required amounts by
the Company to the holders of such Preferred Securities or by causing the
applicable Trust to pay such amounts to such holders.
 
   The Preferred Securities Guarantee is a guarantee from the time of issuance
of the applicable Preferred Securities, but the Preferred Securities Guarantee
covers distributions and other payments on such Preferred Securities only if
and to the extent that the Company has made a payment to the Property Trustee
of interest or
 
                                       11
<PAGE>
 
principal, or premium, if any, on the Junior Subordinated Debt Securities
deposited in the applicable Trust as trust assets. If the Company does not make
interest, principal or premium, if any, payments on the Junior Subordinated
Debt Securities deposited in the applicable Trust as trust assets, the Property
Trustee will not make distributions on the Preferred Securities of such Trust
and the Trust will not have funds available therefor.
 
   The Company's obligations under the Declaration for each Trust, the
Preferred Securities Guarantee issued with respect to Preferred Securities
issued by such Trust, the Junior Subordinated Debt Securities purchased by such
Trust and the Indenture, in the aggregate, will provide a full and
unconditional guarantee on a subordinated basis by the Company of payments due
on the Preferred Securities issued by such Trust.
 
Certain Covenants of the Company
 
   In each Preferred Securities Guarantee, the Company will covenant that, so
long as any Preferred Securities issued by the applicable Trust remain
outstanding, the Company will not (i) declare or pay any dividends on, or
redeem, purchase, acquire or make a distribution or liquidation payment with
respect to, any of its capital stock (other than (a) dividends or distributions
in shares of, or options, warrants, rights to subscribe for or purchase shares
of, common stock of the Company, (b) any declaration of a dividend in
connection with the implementation of a shareholders' rights plan, or the
issuance of stock under any such plan in the future, or the redemption or
repurchase of any such rights pursuant thereto, (c) as a result of a
reclassification of the Company's capital stock or the exchange or the
conversion of one class or series of the Company's capital stock for another
class or series of the Company's capital stock, (d) the payment of accrued
dividends and the purchase of fractional interests in shares of the Company's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged, or (e) purchases of the
Company's common stock related to the issuance of the Company's common stock or
rights under any of the Company's benefit plans for its directors, officers or
employees, any of the Company's dividend reinvestment plans or stock purchase
plans, or any of the benefit plans of any of the Company's affiliates for such
affiliates' directors, officers or employees), (ii) make any payment of
principal or of interest or premium, if any, on or repay, repurchase or redeem
any debt security of the Company that ranks pari passu with or junior in
interest to the Junior Subordinated Debt Securities deposited in such Trust or
(iii) make any guarantee payments with respect to any guarantee by the Company
of the debt securities of any subsidiary of the Company (other than pursuant to
a Preferred Securities Guarantee) if such guarantee ranks pari passu with or
junior in interest to the Junior Subordinated Debt Securities deposited in such
Trust, if at such time (x) the Company shall be in default with respect to its
Guarantee Payments or other payment obligations under the related Preferred
Securities Guarantee, (y) there shall have occurred any Declaration Event of
Default under the applicable Declaration or (z) the Company shall have given
notice of its election to defer payments of interest on the Junior Subordinated
Debt Securities by extending the interest payment period as provided in the
terms of the Junior Subordinated Debt Securities deposited in such Trust as
trust assets and such period, or any extension thereof, is continuing. In
addition, so long as any Preferred Securities of a Trust remain outstanding,
the Company has agreed (i) to remain the sole direct or indirect owner of all
of the outstanding Common Securities of such Trust and not to cause or permit
such Common Securities to be transferred except to the extent permitted by the
applicable Declaration; provided that any permitted successor of the Company
under the Indenture may succeed to the Company's ownership of such Common
Securities and (ii) to use reasonable efforts to cause such Trust to continue
to be treated as a grantor trust for United States federal income tax purposes
except in connection with a distribution of Junior Subordinated Debt Securities
to the holders of such Preferred Securities as provided in the applicable
Declaration.
 
Amendments and Assignment
 
   Except with respect to any changes that do not adversely affect the rights
of holders of Preferred Securities in any material respect (in which case no
consent will be required), each Preferred Securities Guarantee may be amended
only with the prior approval of the Company and the holders of not less than a
majority in liquidation amount of the outstanding Preferred Securities issued
by the applicable Trust. The manner of obtaining any
 
                                       12
<PAGE>
 
such approval of holders of such Preferred Securities will be set forth in an
accompanying prospectus supplement. All guarantees and agreements contained in
a Preferred Securities Guarantee shall bind the successors, assignees,
receivers, trustees and representatives of the Company and shall inure to the
benefit of the holders of the Preferred Securities of the applicable Trust then
outstanding. Except in connection with a consolidation, merger or sale
involving the Company that is permitted under the Indenture, the Company may
not assign its obligations under any Preferred Securities Guarantee.
 
Termination of the Preferred Securities Guarantee
 
   Each Preferred Securities Guarantee will terminate and be of no further
force and effect as to the Preferred Securities issued by the applicable Trust
(i) upon full payment of the redemption price of all Preferred Securities of
such Trust, (ii) upon distribution of the Junior Subordinated Debt Securities
to the holders of the Trust Securities of such Trust in exchange for all of the
Trust Securities issued by such Trust or (iii) upon full payment of the amounts
payable in accordance with the applicable Declaration upon liquidation of such
Trust. Notwithstanding the foregoing, each Preferred Securities Guarantee will
continue to be effective or will be reinstated, as the case may be, if at any
time any holder of Preferred Securities issued by the applicable Trust must
restore payment of any sums paid with respect to such Preferred Securities or
under such Preferred Securities Guarantee.
 
Status of the Preferred Securities Guarantee
 
   The Company's obligation under each Preferred Securities Guarantee to make
the Guarantee Payments will constitute an unsecured obligation of the Company
and will rank (i) subordinate and junior in right of payment to all other
liabilities of the Company, including the Junior Subordinated Debt Securities,
except those made pari passu or subordinate by their terms, and (ii) senior to
all capital stock (other than the most senior preferred stock issued, from time
to time, if any, by the Company, which preferred stock will rank pari passu
with each Preferred Securities Guarantee) now or hereafter issued by the
Company and to any guarantee now or hereafter entered into by the Company in
respect of any of its capital stock (other than the most senior preferred stock
issued, from time to time, if any, by the Company). The Company's obligations
under each Preferred Securities Guarantee will rank pari passu with respect to
obligations under other guarantee agreements which it may enter into from time
to time to the extent that (i) such agreements shall be entered into in
substantially the form of the Preferred Securities Guarantee and provide for
comparable guarantees by the Company of payment on preferred securities issued
by other trusts, partnerships or other entities affiliated with the Company
that are financing vehicles of the Company and (ii) the debentures or other
evidences of indebtedness of the Company relating to such preferred securities
are junior subordinated, unsecured indebtedness of the Company. The Company's
obligations under each Preferred Securities Guarantee are effectively
subordinated to all existing and future liabilities, including trade payables,
of the Company's subsidiaries, except to the extent that the Company is a
creditor of the subsidiaries and is recognized as such. Each Declaration
provides that each holder of Preferred Securities by acceptance thereof agrees
to the subordination provisions and other terms of the related Preferred
Securities Guarantee.
 
   Each Preferred Securities Guarantee will constitute a guarantee of payment
and not merely of collection (that is, the guaranteed party may institute a
legal proceeding directly against the guarantor to enforce its rights under the
guarantee without first instituting a legal proceeding against any other person
or entity). Each Preferred Securities Guarantee will be deposited with the
Guarantee Trustee, as indenture trustee, to be held for the benefit of the
holders of the Preferred Securities issued by the applicable Trust. The
Guarantee Trustee will have the right to enforce the Preferred Securities
Guarantee on behalf of the holders of the Preferred Securities issued by the
applicable Trust. The holders of not less than a majority in aggregate
liquidation amount of the Preferred Securities issued by the applicable Trust
will have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee in respect of the
related Preferred Securities Guarantee or exercising any trust or other power
conferred upon the Guarantee Trustee under such Preferred Securities Guarantee.
If the Guarantee Trustee fails to enforce such Preferred Securities Guarantee
as above provided, any holder of Preferred Securities issued by the applicable
Trust may institute a legal
 
                                       13
<PAGE>
 
proceeding directly against the Company to enforce its rights under such
Preferred Securities Guarantee without first instituting a legal proceeding
against the applicable Trust, the Guarantee Trustee or any other person or
entity. Notwithstanding the foregoing, if the Company has failed to make a
Guarantee Payment, a holder of Preferred Securities may directly institute a
proceeding against the Company for enforcement of the applicable Preferred
Securities Guarantee for such payment without first instituting a legal
proceeding against the applicable Trust, the Guarantee Trustee or any other
person or entity.
 
Miscellaneous
 
   The Company will be required to provide annually to the Guarantee Trustee a
statement as to the performance by the Company of certain of its obligations
under each Preferred Securities Guarantee and as to any default in such
performance. The Company is required to file annually with the Guarantee
Trustee an officers' certificate as to the Company's compliance with all
conditions under each Preferred Securities Guarantee.
 
   The Guarantee Trustee, prior to the occurrence of an event of default under
a Preferred Securities Guarantee and after the curing or waiving of all events
of default that may have occurred, will undertake to perform only such duties
as are specifically set forth in the applicable Preferred Securities Guarantee,
and no implied covenants will be read into such Preferred Securities Guarantee.
After a default with respect to a Preferred Securities Guarantee has occurred,
the Guarantee Trustee shall exercise such of the rights and powers vested in it
by such Preferred Securities Guarantee, and use the same degree of care and
skill in its exercise thereof as a prudent person would exercise or use under
the circumstances in the conduct of his or her own affairs. Subject to such
provision, the Guarantee Trustee is under no obligation to exercise any of the
rights or powers vested in it by a Preferred Securities Guarantee at the
request or direction of any holder of the applicable Preferred Securities
unless it is offered security and indemnity satisfactory to it against the
costs, expenses and liabilities that might be incurred thereby.
 
Governing Law
 
   Each Preferred Securities Guarantee will be governed by, and construed in
accordance with, the laws of the State of New York.
 
             DESCRIPTION OF THE JUNIOR SUBORDINATED DEBT SECURITIES
 
   The Company may issue from time to time one or more series of Junior
Subordinated Debt Securities ("Junior Subordinated Debt Securities") under a
Junior Subordinated Indenture (the "Indenture") between the Company and The
Bank of New York, as trustee (the "Indenture Trustee"). The Indenture will be
qualified under the Trust Indenture Act. The form of the Indenture has been
filed as an exhibit to the registration statement of which this prospectus
forms a part. The following description summarizes the material terms of the
Indenture, and is qualified in its entirety by reference to the Indenture and
the Trust Indenture Act. Whenever particular provisions or defined terms in the
Indenture are referred to herein, such provisions or defined terms are
incorporated by reference herein. Section and article references used herein
are references to provisions of the Indenture.
 
General
 
   The Junior Subordinated Debt Securities will be unsecured junior
subordinated obligations of the Company. The Indenture does not limit the
amount of additional indebtedness the Company or any of its subsidiaries may
incur. The Company's rights and the rights of its creditors, including the
holders of Junior Subordinated Debt Securities, to participate in the assets of
any subsidiary of the Company upon the latter's liquidation or recapitalization

Certain Covenants of the Company Applicable to the Junior Subordinated Debt
Securities
 
   If Junior Subordinated Debt Securities are issued to a Trust in connection
with the issuance of Trust Securities by such Trust, the Company will covenant
in the Indenture that, so long as the Preferred Securities issued by the
applicable Trust remain outstanding, the Company will not (i) declare or pay
any dividends on, or redeem, purchase, acquire or make a distribution or
liquidation payment with respect to, any of its capital stock (other than (a)
dividends or distributions in shares of, or options, warrants, rights to
subscribe for or purchase shares of, common stock of the Company, (b) any
declaration of a dividend in connection with the implementation of a
stockholders' rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto,
(c) as a result of a reclassification of the Company's capital stock or the
exchange or the conversion of one class or series of the Company's capital
stock for another class or series of the Company's capital stock, (d) the
payment of accrued dividends and the purchase of fractional interests in shares
of the Company's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged,
or (e) purchases of the Company's common stock related to the issuance of the
Company's common stock or rights under any of the Company's benefit plans for
its directors, officers, employees, any of the Company's dividend reinvestment
plans or stock purchase plans, or any of the benefit plans of any of the
Company's affiliates for such affiliates' directors, officers or employees),
(ii) make any payment of principal or of interest or premium, if any, on or
repay, repurchase or redeem any debt security of the Company that, ranks pari
passu with or junior in interest to the Junior Subordinated Debt Securities
deposited in such Trust or (iii) make any guarantee payments with respect to
any guarantee by the Company of the debt securities of any subsidiary of the
Company (other than pursuant to a Preferred Securities Guarantee) if such
guarantee ranks pari passu with or junior in interest to the Junior
Subordinated Debt Securities deposited in such Trust, if at such time (x) the
Company shall be in default with respect to its Guarantee Payments or other
payment obligations under the related Preferred Securities Guarantee, (y) there
shall have occurred any Indenture Event of Default with respect to the Junior
Subordinated Debt Securities deposited in such Trust as Trust assets or (z) the
Company shall have given notice of its election to defer payments of interest
on the Junior Subordinated Debt Securities by extending the interest payment
period as provided in the terms of the Junior Subordinated Debt Securities
deposited in such Trust as Trust assets and such period, or any extension
thereof, is continuing. In addition, if Junior Subordinated Debt Securities are
issued to a Trust in connection with the issuance of Trust Securities by such
Trust, for so long as any Preferred Securities issued by the applicable Trust
remain outstanding, the Company has agreed (i) to remain the sole direct or
indirect owner of all of the outstanding Common Securities issued by the
applicable Trust and not to cause or permit such Common Securities to be
transferred except to the extent permitted by the applicable Declaration;
provided that any permitted successor of the Company under the Indenture may
succeed to the Company's ownership of the Common Securities issued by the
applicable Trust, (ii) to comply fully with all of its obligations and
agreements contained in the related Declaration and (iii) to use reasonable
efforts to cause the applicable Trust to continue to be treated as a grantor
trust for United States federal income tax purposes except in connection with a
distribution of Junior Subordinated Debt Securities to holders of Preferred
Securities issued by the applicable Trust as provided in the related
Declaration.
 
Subordination
 
   The payment of principal of, premium, if any, and interest on the Junior
Subordinated Debt Securities will, to the extent and in the manner set forth in
the Indenture, be subordinated and junior in right of payment to the prior
payment in full, in cash or cash equivalents, of all Senior Debt of the Company
whether outstanding on the date of this prospectus or thereafter incurred.
 
   Upon any payment by the Company or distribution of assets of the Company to
creditors upon any liquidation, dissolution, winding up, receivership,
reorganization, assignment for the benefit of creditors,
 
                                       16
<PAGE>
 
marshaling of assets and liabilities or any bankruptcy, insolvency or similar
proceedings of the Company, the holders of all Senior Debt will first be
entitled to receive payment in full of all amounts due or to become due thereon
before the holders of the Junior Subordinated Debt Securities will be entitled
to receive any payment in respect of the principal of, premium, if any, or
interest on the Junior Subordinated Debt Securities.
 
   In the event and during the continuation of any default by the Company in
the payment of principal, premium, interest or any other payment due on any
Senior Debt, or in the event that the maturity of any Senior Debt has been
accelerated because of a default, then, in either case, no payment shall be
made by the Company with respect to the principal (including redemption
payments) of or premium, if any, or interest on the Junior Subordinated Debt
Securities until such default shall have been cured or waived in writing or
shall have ceased to exist or such Senior Debt shall have been discharged or
paid in full.
 
   In the event of the acceleration of the maturity of the Junior Subordinated
Debt Securities, then no payments shall be made by the Company with respect to
the principal (including redemption payments) of or premium, if any, or
interest on the Junior Subordinated Debt Securities until the holders of all
Senior Debt outstanding at the time of such acceleration shall receive payment
in full of such Senior Debt (including any amounts due upon acceleration).
 
   In the event that, notwithstanding the foregoing, any payment shall be
received by the Indenture Trustee or any holder of Junior Subordinated Debt
Securities when such payment is prohibited by the preceding paragraphs, such
payment shall be held in trust for the benefit of, and shall be paid over or
delivered to, the holders of Senior Debt or their respective representatives,
or to the trustee or trustees under any indenture pursuant to which any of such
Senior Debt may have been issued, as their respective interests may appear.
 
   By reason of such subordination, in the event of insolvency of the Company,
funds that would otherwise be payable to holders of Junior Subordinated Debt
Securities will be paid to the holders of Senior Debt of the Company to the
extent necessary to pay such Senior Debt in full, and the Company may be unable
to meet fully its obligations with respect to the Junior Subordinated Debt
Securities.
 
   "Debt" is defined to mean, with respect to any person at any date of
determination (without duplication), (i) all indebtedness of such person for
borrowed money, (ii) all obligations of such person evidenced by bonds,
debentures, notes or other similar instruments, including obligations incurred
in connection with the acquisition of property, assets or businesses, (iii) all
obligations of such person in respect of letters of credit or bankers'
acceptances or other similar instruments (or reimbursement obligations with
respect thereto) issued on the account of such person, (iv) all obligations of
such person to pay the deferred purchase price of property or services, except
certain trade payables, (v) all obligations of such person as lessee under
capitalized leases, (vi) all Debt of others secured by a lien on any asset of
such person, whether or not such Debt is assumed by such person; provided that,
for purposes of determining the amount of any Debt of the type described in
this clause, if recourse with respect to such Debt is limited to such asset,
the amount of such Debt shall be limited to the lesser of the fair market value
of such asset or the amount of such Debt, (vii) all Debt of others guaranteed
by such person to the extent such Debt is guaranteed by such person and (viii)
to the extent not otherwise included in this definition, all obligations of
such person for claims in respect of derivative products, including interest
rate, foreign exchange rate and commodity prices, forward contracts, options,
swaps, collars and similar arrangements.
 
   "Senior Debt" is defined to mean the principal of (and premium, if any) and
interest on all Debt of the Company whether created, incurred or assumed
before, on or after the date of the Indenture; provided that such Senior Debt
shall not include (i) Debt of the Company that, when incurred and without
respect to any election under Section 1111(b) of Title 11, U.S. Code, was
without recourse and (ii) any other Debt of the Company which by the terms of
the instrument creating or evidencing the same is specifically designated as
being subordinated to or pari passu with the Junior Subordinated Debt
Securities, and in particular the Junior Subordinated Debt Securities shall
rank pari passu with all other debt securities and guarantees issued to any
trust, partnership or other entity affiliated with the Company which is a
financing vehicle of the Company in connection with an issuance of preferred
securities by such financing entity.

Indenture Events of Default
 
   The Indenture provides that any one or more of the following described
events, which has occurred and is continuing, constitutes an "Indenture Event
of Default" with respect to each series of Junior Subordinated Debt Securities:
 
     (a) failure for 30 days to pay interest on the Junior Subordinated Debt
  Securities of such series when due; provided that a valid extension of the
  interest payment period by the Company shall not constitute a default in
  the payment of interest for this purpose;
 
     (b) failure to pay principal of or premium, if any, on the Junior
  Subordinated Debt Securities of such series when due whether at maturity,
  upon redemption, by declaration or otherwise;
 
     (c) failure for 30 days to pay any sinking fund or analogous fund
  payment with respect to the Junior Subordinated Debt Securities of such
  series;
 
     (d) failure to duly observe or perform, in any material respect, any
  other covenant or agreement contained in the Indenture with respect to such
  series for 90 days after written notice to the Company from the Indenture
  Trustee or the holders of at least 25% in principal amount of the
  outstanding Junior Subordinated Debt Securities of such series;
 
     (e) certain events in bankruptcy, insolvency or reorganization of the
  Company; or
 
     (f) any other Indenture Event of Default applicable to the Junior
  Subordinated Debt Securities of such series. (Section 6.01)
 
   In each and every such case, unless the principal of all the Junior
Subordinated Debt Securities of that series shall have already become due and
payable, either the Indenture Trustee or the holders of not less than 25% in
aggregate principal amount of the Junior Subordinated Debt Securities of that
series then outstanding, by notice in writing to the Company (and to the
Indenture Trustee if given by such holders), may declare the principal of all
the Junior Subordinated Debt Securities of that series to be due and payable
immediately, and upon any such declaration the same shall become and shall be
immediately due and payable. (Section 6.01)
 
   The holders of a majority in aggregate outstanding principal amount of the
Junior Subordinated Debt Securities of that series have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Indenture Trustee or exercising any trust or power conferred on the
Indenture Trustee with respect to such series. (Section 6.06) The Indenture
Trustee or the holders of not less than 25% in aggregate outstanding principal
amount of the Junior Subordinated Debt Securities of that series may declare
the principal due and payable immediately upon an Indenture Event of Default
with respect to such series, but the holders of a majority in aggregate
outstanding principal amount of Junior Subordinated Debt Securities of such
series may rescind and annul such declaration and waive the default if the
default has been cured and a sum sufficient to pay all matured installments of
interest and principal otherwise than by acceleration and any premium has been
deposited with the Indenture Trustee. (Sections 6.01 and 6.06)
 
   The holders of a majority in aggregate outstanding principal amount of the
Junior Subordinated Debt Securities of that series may, on behalf of the
holders of all the Junior Subordinated Debt Securities of that series, waive
any past default, except a default in the payment of principal, premium, if
any, or interest (unless such default has been cured and a sum sufficient to
pay all matured installments of interest and principal otherwise than by
acceleration and any premium has been deposited with the Indenture Trustee) or
a call for redemption of the Junior Subordinated Debt Securities of that
series. (Section 6.06) The Company is required to file annually with the
Indenture Trustee a certificate as to whether or not the Company is in
compliance with all the conditions and covenants under the Indenture. (Section
5.03)
 
   If Junior Subordinated Debt Securities are issued to a Trust in connection
with the issuance of Trust Securities of such Trust, then under the applicable
Declaration an Indenture Event of Default with respect to such series of Junior
Subordinated Debt Securities will constitute a Declaration Event of Default. If
a Declaration Event of Default under the applicable Declaration has occurred
and is continuing and such event is
 
                                       18
<PAGE>
 
attributable to the failure of the Company to pay interest or principal, or
premium, if any, on the applicable series of Junior Subordinated Debt
Securities on the date such interest, principal or premium is otherwise payable
(or in the case of redemption, on the redemption date), then a holder of
Preferred Securities of such Trust may directly institute a Holder Direct
Action on or after the respective due date specified in the applicable series
of Junior Subordinated Debt Securities (see "The Trusts--The Property
Trustee"). In connection with such Holder Direct Action, the Company will be
subrogated to the rights of such holder of Preferred Securities under the
applicable Declaration to the extent of any payment made by the Company to such
holder of Preferred Securities in such Holder Direct Action. Except as
expressly provided in the preceding sentences or in the applicable prospectus
supplement, the holders of Preferred Securities of such Trust will not be able
to exercise directly any other remedy available to the holders of the
applicable series of Junior Subordinated Debt Securities.
 
Modification of the Indenture
 
   From time to time the Company and the Indenture Trustee may, without the
consent of the holders of Junior Subordinated Debt Securities, amend the
Indenture or indentures supplemental thereto for one or more of the following
purposes: (a) to evidence the succession of another corporation or other entity
to the Company under the Indenture and the Junior Subordinated Debt Securities
and the assumption by such successor corporation or other entity of the
obligations of the Company thereunder; (b) to add further covenants,
restrictions, conditions or provisions for the protection of the holders of
Junior Subordinated Debt Securities; (c) to cure any ambiguity or to correct or
supplement any provision which may be defective or inconsistent with any other
provision; (d) to add to, change or eliminate any of the provisions of the
Indenture, provided that any such addition, change or elimination shall become
effective only after there are no such Junior Subordinated Debt Securities of
any series entitled to the benefit of such provision outstanding; (e) to
provide for the issuance of Junior Subordinated Debt Securities in coupon form;
(f) to evidence and provide for the acceptance of a successor trustee; (g) to
qualify or maintain the qualification of the Indenture under the Trust
Indenture Act; (h) to establish the form or terms of a series of Junior
Subordinated Debt Securities; and (i) to make any addition, change or
elimination of any provision of the Indenture that does not adversely affect
the rights of any holder of Junior Subordinated Debt Securities in any material
respect. (Section 9.01)
 
   The Indenture contains provisions permitting the Company and the Indenture
Trustee, with the consent of the holders of not less than a majority in
principal amount of the outstanding Junior Subordinated Debt Securities of each
series affected by such modification, to modify the Indenture or any
supplemental indenture affecting the rights of the holders of such Junior
Subordinated Debt Securities; provided that no such modification may, without
the consent of the holder of each outstanding Subordinated Debt Security
affected thereby, (i) extend the fixed maturity of the Junior Subordinated Debt
Securities of any series, reduce the principal amount thereof, reduce the rate
or extend the time of payment of interest thereon, reduce any premium payable
upon the redemption thereof or (ii) reduce the percentage of Junior
Subordinated Debt Securities, the holders of which are required to consent to
any such modification. (Section 9.02)
 
Book-Entry and Settlement
 
   If any Junior Subordinated Debt Securities of a series are represented by
one or more global securities (each, a "Global Security"), the applicable
prospectus supplement will describe the circumstances, if any, under which
beneficial owners of interests in any such Global Security may exchange such
interests for Junior Subordinated Debt Securities of such series and of like
tenor and principal amount in any authorized form and denomination. Principal
of and any premium and interest on a Global Security will be payable in the
manner described in the applicable prospectus supplement.
 
   The specific terms of the depositary arrangement with respect to any portion
of a series of Junior Subordinated Debt Securities to be represented by a
Global Security will be described in the applicable prospectus supplement.

Consolidation, Merger and Sale
 
   The Indenture will provide that the Company may not consolidate with or
merge into any other person or convey, transfer or lease its properties and
assets substantially as an entirety to any person and may not permit any person
to merge into or consolidate with the Company unless (i) either the Company
will be the resulting or surviving entity or any successor or purchaser is a
corporation, limited liability company, partnership or trust organized under
the laws of the United States of America, any State or the District of
Columbia, and any such successor or purchaser expressly assumes the Company's
obligations under the Junior Subordinated Debt Securities and the Indenture and
(ii) immediately after giving effect to the transaction no Event of Default,
and no event which, after notice or lapse of time or both, would become an
Event of Default shall have occurred and be continuing. (Section 10.01)
 
Defeasance and Discharge
 
   Under the terms of the Indenture, the Company will be discharged from any
and all obligations in respect of a series of the Junior Subordinated Debt
Securities (except in each case for certain obligations to register the
transfer or exchange of such Junior Subordinated Debt Securities, replace
stolen, lost or mutilated Junior Subordinated Debt Securities of such series,
maintain paying agencies and hold moneys for payment in trust) if (i) the
Company irrevocably deposits with the Indenture Trustee cash or U.S. Government
Obligations or a combination thereof, as trust funds in an amount certified to
be sufficient to pay at maturity (or upon redemption) the principal of,
premium, if any, and interest on all outstanding Junior Subordinated Debt
Securities of such series; (ii) such deposit will not result in a breach or
violation of, or constitute a default under, any agreement or instrument to
which the Company is a party or by which it is bound; (iii) the Company
delivers to the Indenture Trustee an opinion of counsel to the effect that the
holders of the Junior Subordinated Debt Securities of such series will not
recognize income, gain or loss for United States federal income tax purposes as
a result of such defeasance and discharge and that such defeasance and
discharge will not otherwise alter holders' United States federal income tax
treatment of principal, premium and interest payments on such Junior
Subordinated Debt Securities of such series (such opinion must be based on a
ruling of the Internal Revenue Service or a change in United States federal
income tax law occurring after the date of the Indenture, since such a result
would not occur under current tax law); (iv) the Company has delivered to the
Indenture Trustee an officers' certificate and an opinion of counsel, each
stating that all conditions precedent provided for relating to the defeasance
and discharge contemplated by such provision have been complied with; and (v)
no event or condition shall exist that pursuant to the applicable subordination
provisions, would prevent the Company from making payments of principal of,
premium, if any, and interest on the Junior Subordinated Debt Securities at the
date of the irrevocable deposit referred to above. (Section 11.01)
 
Governing Law
 
   The Indenture and the Junior Subordinated Debt Securities will be governed
by the laws of the State of New York. (Section 13.05)
 
Information Concerning the Indenture Trustee
 
   The Indenture Trustee, prior to the occurrence of an Indenture Event of
Default and after the curing of all Indenture Events of Default undertakes to
perform only such duties as are specifically set forth in the Indenture and,
after an Indenture Event of Default has occurred (which has not been cured or
waived), shall exercise such of the rights and powers vested in it by the
Indenture and use the same degree of care and skill in their exercise as a
prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs. (Section 7.01) Subject to such provision, the Indenture
Trustee is under no obligation to exercise any of the powers vested in it by
the Indenture at the request of any holder of Junior Subordinated Debt
Securities, unless offered security or indemnity satisfactory to it by such
holder against the costs, expenses and liabilities that might be incurred
thereby. (Section 7.02) The Indenture Trustee is not required to expend or risk
its own funds or otherwise incur personal financial liability in the
performance of its duties or in the exercise of any of its
 
                                       20
<PAGE>
 
rights or powers if there is reasonable ground for believing that the repayment
of such funds or liability is not reasonably assured to it under the terms of
the Indenture or adequate indemnity against such risk is not reasonably assured
to it. (Section 7.01)
 
   The Company and its subsidiaries maintain commercial banking and trust
relationships with the Indenture Trustee and its affiliates.
 
Miscellaneous
 
   The Company will have the right at all times to assign any of its rights or
obligations under the Indenture to an affiliate; provided that, in the event of
any such assignment, the Company will remain jointly and severally liable for
all such obligations. Subject to the foregoing, the Indenture will be binding
upon and inure to the benefit of the parties thereto and their respective
successors and assigns. The Indenture provides that it may not otherwise be
assigned by the parties thereto other than by the Company to a successor or
purchaser pursuant to a consolidation, merger, sale or conveyance permitted by
the Indenture. (Section 13.11)
 
                              PLAN OF DISTRIBUTION
 
   The Company may sell any series of Junior Subordinated Debt Securities and
each Trust may sell its Preferred Securities (the Junior Subordinated Debt
Securities and the Preferred Securities are collectively referred to herein as
the "Offered Securities") being offered hereby in any of three ways (or in any
combination thereof): (i) through underwriters or dealers; (ii) directly to a
limited number of purchasers or to a single purchaser; or (iii) through agents.
The prospectus supplement with respect to any Offered Securities will set forth
the terms of the offering of such Offered Securities, including the name or
names of any underwriters, dealers or agents and the respective amounts of such
Offered Securities underwritten or purchased by each of them, the initial
public offering price of such Offered Securities and the proceeds to the
Company or the applicable Trust, as the case may be, from such sale, any
discounts, commissions or other items constituting compensation from the
Company or the applicable Trust, as the case may be, and any discounts,
commissions or concessions allowed or reallowed or paid to dealers and any
securities exchanges on which such Offered Securities may be listed. Any public
offering price and any discounts or concessions allowed or reallowed or paid to
dealers may be changed from time to time.
 
   If underwriters are used in the sale of any Offered Securities, such Offered
Securities will be acquired by the underwriters for their own account and may
be resold from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
at the time of sale. Such Offered Securities may be either offered to the
public through underwriting syndicates represented by managing underwriters, or
directly by underwriters. Unless otherwise set forth in the prospectus
supplement, the obligations of the underwriters to purchase such Offered
Securities will be subject to certain conditions precedent and the underwriters
will be obligated to purchase all of such Offered Securities if any are
purchased.
 
   Offered Securities may be sold directly by the Company or a Trust, as the
case may be, or through agents designated by the Company or such Trust, as the
case may be, from time to time. Any agent involved in the offer or sale of
Offered Securities in respect of which this prospectus is delivered will be
named, and any commissions payable by the Company or the applicable Trust, as
the case may be, to such agent will be set forth, in the prospectus supplement.
Unless otherwise indicated in the prospectus supplement, any such agent will be
acting on a best efforts basis for the period of its appointment.
 
   If so indicated in the prospectus supplement, the Company or the applicable
Trust, as the case may be, will authorize underwriters, dealers or agents to
solicit offers by certain purchasers to purchase Offered Securities from the
Company or the applicable Trust, as the case may be, at the public offering
price set forth in the prospectus supplement pursuant to delayed delivery
contracts providing for payment and delivery on a specified date in the future.
Such contracts will be subject only to those conditions set forth in the
prospectus

supplement, and the prospectus supplement will set forth the commission payable
for solicitation of such contracts.
 
   Agents and underwriters may be entitled under agreements entered into with
the Company and the applicable Trust to indemnification by the Company and the
applicable Trust against certain civil liabilities, including liabilities under
the Securities Act, or to contribution with respect to payments which the
agents or underwriters may be required to make in respect thereof. Agents and
underwriters may be customers of, engage in transactions with, or perform
services for the Company, the applicable Trust and/or any of their affiliates
in the ordinary course of business.
 
   Certain persons participating in the offering may engage in transactions
that stabilize, maintain or otherwise affect the price of the Offered
Securities. In connection with the offering, the underwriters or agents, as the
case may be, may purchase and sell the Offered Securities in the open market.
These transactions may include overallotment and stabilizing transactions and
purchases to cover syndicate short positions created in connection with the
offering. Stabilizing transactions consist of certain bids or purchases for the
purpose of preventing or retarding a decline in the market price of the Offered
Securities; and syndicate short positions involve the sale by the underwriters
or agents, as the case may be, of a greater number of Offered Securities than
they are required to purchase from the Company or the applicable Trust, as the
case may be, in the offering. The underwriters may also impose a penalty bid,
whereby selling concessions allowed to syndicate members or other broker-
dealers for the Offered Securities sold for their account may be reclaimed by
the syndicate if such Offered Securities are repurchased by the syndicate in
stabilizing or covering transactions. These activities may stabilize, maintain
or otherwise affect the market price of the Offered Securities, which may be
higher than the price that might otherwise prevail in the open market, and, if
commenced, may be discontinued at any time. These transactions may be effected
on the New York Stock Exchange, in the over-the-counter market or otherwise.
For a description of these activities, see "Plan of Distribution" or
"Underwriting" in the relevant prospectus supplement.
 
   Unless otherwise indicated in the prospectus supplement, the Company does
not intend to list any of the Offered Securities on a national securities
exchange. No assurances can be given that there will be a market for the
Offered Securities.
