                                  THE COMPANY

    We are a global power company incorporated in Delaware on January 28, 1981.
We are committed to serving the world's need for electricity and other services
in a socially responsible way.

    We have been successful in growing our business and serving additional
customers by, in part, participating in competitive bidding under privatization
initiatives. We have been particularly interested in acquiring existing
businesses or assets in electricity markets that are promoting competition and
eliminating rate of return regulation. Sellers generally seek to complete such
transactions in less than one year, much quicker than the time periods
associated with greenfield development and usually require payment in full on
transfer. We believe that our experience in competitive markets and our
worldwide integrated group structure, with our significant geographic coverage
and presence, enable us to react quickly and creatively in these situations. Our
significant growth has resulted in generating capacity of 42,133 megawatts or MW
at December 31, 2000, with a total of 141 plants in operation.

    Our ownership portfolio of power facilities includes new plants constructed
for such purposes as well as existing power plants acquired through
competitively bid privatization initiatives and negotiated acquisitions. In the
electricity generation business, we now own and operate (entirely or in part) a
diverse portfolio of electric power plants (including those within integrated
distribution companies) with, as of December 31, 2000, capacity of 42,133 MW. Of
that total, 38% are fueled by coal or petroleum coke, 18% are fueled by natural
gas, 33% are hydroelectric facilities, 4% are fueled by oil, and the remaining
7% are capable of using multiple fossil fuels. A majority of our sales of
electricity are made to customers (generally electric utilities or regional
electric companies), on a wholesale basis for further resale to end users. This
is referred to as the electricity "generation" business. Sales by these
generation companies are made under long-term contracts from power plants owned
by our subsidiaries and affiliates as well as directly into regional electricity
markets without contracts.

    We also sell electricity directly to end users such as commercial,
industrial, governmental and residential customers through our "distribution"
business. We have ownership interests in distribution companies in Argentina,
India, the United States, Brazil, Venezuela, El Salvador, Dominican Republic,
and The Republic of Georgia. We also have assumed management control of a heat
and electricity distribution business in Kazakhstan. In addition we have less
than majority ownership in three additional distribution companies in Brazil and
one in India. These distribution companies serve a total of over 18 million
customers with annual sales exceeding 126,000 gigawatt hours, as of
December 31, 2000. On a net equity basis, our ownership represents approximately
6.2 million customers and annual sales exceeding over 48,000 gigawatt hours, as
of December 31, 2000. We also have three subsidiaries in the United States that
serve retail customers in those states that have introduced a competitive market
for the sale of electricity to end users.

                              RECENT DEVELOPMENTS

FIRST QUARTER RESULTS OF OPERATIONS

    Net income, before deducting the noncash foreign currency transaction losses
at Brazilian affiliates and the nonrecurring acquisition costs recorded in
conjunction with the IPALCO pooling of interests transaction, was $226 million
for the quarter ended March 31, 2001, an increase of 19% over the comparative
results for the first quarter of 2000. As a result of the pooling transaction,
the results of operations of AES for the quarter ended March 31, 2000 have also
been restated to include IPALCO. Diluted earnings per share, excluding the
noncash transaction losses and the nonrecurring acquisition costs, were $0.42
for the quarter, compared to $0.38 (before foreign currency effects and
nonrecurring items) for the same quarter in 2000. Net income, after all charges,
was $106 million for the quarter. Revenues for the quarter were $2.5 billion, an
increase of 50% from the first quarter of 2000.

                              DESCRIPTION OF NOTES

The Senior Notes will be issued under an indenture dated as of December 8, 1998
and a supplemental indenture, dated as of February 22, 2001, each between the
Company and Bank One, National Association (formerly known as The First National
Bank of Chicago), as trustee (the "Trustee") (collectively, the "Indenture").
The following summaries of certain provisions of the Indenture do not purport to
be complete and are subject to, and are qualified in their entirety by reference
to, all of the provisions of the Indenture, including the definition in the
Indenture of certain terms. Wherever particular sections or defined terms of the
Indenture are referred to, such sections or defined terms are incorporated in
this prospectus supplement by reference. A copy of the Indenture is available
for inspection at the office of the Trustee.

    As used herein, the term "AES" means The AES Corporation, and does not
include any of its subsidiaries.

    The Indenture does not limit the aggregate principal amount of indebtedness
which may be issued thereunder and provides that senior debt securities may be
issued thereunder from time to time in one or more series. The Senior Notes
constitute a separate series under the Indenture.

GENERAL

    The L50,000,000 of Senior Notes offered hereby are the same series of Senior
Notes as the L85,000,000 aggregate principal amount of Senior Notes issued on
February 22, 2001 pursuant to the same Indenture. The Senior Notes will not be
limited in aggregate principal amount. Additional Senior Notes may be issued
under the Indenture from time to time as part of this series of Senior Notes.

    The entire principal amount of the Senior Notes will mature and become due
and payable, together with any accrued and unpaid interest thereon, on March 1,
2011. The Senior Notes are not subject to any sinking fund provision.

    Senior Notes will only be sold in a minimum aggregate principal amount of
L1,000 and integral multiples thereof.

INTEREST

    Each Senior Note shall bear interest at 8.375% per annum from February 22,
2001, payable semi annually on March 1 and September 1 of each year to the
person in whose name such Senior Note is registered at the close of business on
the fifteenth calendar day of the month preceding such payment date. The initial
interest payment date is September 1, 2001. The amount of interest payable will
be computed on the basis of a 360-day year of twelve 30-day months. In the event
that any date on which interest is payable on the Senior Notes is not a business
day, then payment of the interest payable on such date will be made on the next
succeeding day which 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 such date.

LISTING OF SENIOR NOTES ON THE LUXEMBOURG STOCK EXCHANGE

    We have applied to list the Senior Notes on the Luxembourg Stock Exchange in
accordance with the rules of the Luxembourg Stock Exchange. In connection with
the Luxembourg Stock Exchange listing application, the legal notice relating to
the issuance of the Senior Notes and AES's constitutional documents will be
deposited with the Registrar of the District Court in Luxembourg (GREFFIER EN
CHEF DU TRIBUNAL D'ARRONDISSEMENT DE ET A LUXEMBOURG) where such documents may
be examined and copies thereof may be obtained upon request. Additionally,
copies of the above documents together with this prospectus supplement, the
accompanying prospectus, the Indenture and AES's current annual and quarterly
reports, as well as all its future annual reports and quarterly reports, so long
as any of the Senior Notes are outstanding, will be made available for
inspection by any interested party, free of charge at the main office of Banque
Internationale a Luxembourg S.A. in Luxembourg. Banque

                                      S-9

Internationale a Luxembourg S.A. will act as intermediary between the Luxembourg
Stock Exchange, AES and the holders of the Senior Notes. In addition, copies of
the annual reports and quarterly reports of AES may be obtained free of charge
at such office.

    As long as any Senior Notes are listed on the Luxembourg Stock Exchange and
so long as the rules of such exchange so require, an agent for making payments
on, and transfers of, Senior Notes will be maintained in Luxembourg. AES has
initially designated Banque Internationale a Luxembourg S.A. for such purposes.

OPTIONAL REDEMPTION

    The Senior Notes are subject to redemption upon not less than 30 nor more
than 60 days' notice by mail, at any time, as a whole or in part, at the
election of AES, at a price equal to the sum of (i) 100% of the principal amount
thereof plus accrued interest to the redemption date plus (ii) the Make-Whole
Amount, if any.

    The term "Make-Whole Amount" shall mean, in connection with any optional
redemption of any Senior Note, the excess, if any, of (i) the aggregate present
value as of the date of such redemption of the principal being redeemed and the
amount of interest (exclusive of interest accrued to the redemption date) that
would have been payable in respect of such amount had such prepayment not been
made, determined by discounting, on a semiannual basis, such principal and
interest at the Reinvestment Rate (determined on the business day preceding the
date of such redemption) from the respective dates on which such principal and
interest would have been payable if such payment had not been made, over
(ii) the aggregate principal amount of the Senior Notes being redeemed.

    The term "Reinvestment Rate" shall mean 0.50% (one-half of one percent) plus
the Gilt Rate.

    "Gilt Rate" is defined to mean the yield to maturity at the time of
computation of United Kingdom government securities with a constant maturity as
compiled by the Office for National Statistics and published in the most recent
financial statistics that have become publicly available at least two business
days in London prior to the date fixed for redemption, most nearly equal to then
remaining years to the stated maturity of the principal being redeemed (the
"Stated Maturity"); provided that if the number of years to the Stated Maturity
is not equal to the constant maturity of a United Kingdom government security
for which a weekly average yield is given, the Gilt Rate shall be obtained by
linear interpolation, calculated to the nearest one-twelfth of a year, from the
weekly average yields of United Kingdom government securities for which such
yields are given except that if the number of years to the Stated Maturity is
less than one year, the weekly average yield on actually traded United Kingdom
government securities adjusted to a constant maturity of one year shall be used.

CERTAIN COVENANTS OF AES

    RESTRICTIONS ON SECURED DEBT.  If AES shall incur, issue, assume or
guarantee any indebtedness for borrowed money represented by notes, bonds,
debentures or other similar evidences of indebtedness, secured by a mortgage,
pledge or other lien on any Principal Property (as defined below) or any capital
stock or indebtedness held directly by AES of any Subsidiary of AES (as defined
below), AES shall secure the Senior Notes equally and ratably with (or prior to)
such indebtedness, so long as such indebtedness shall be so secured, unless
after giving effect thereto the aggregate amount of all such indebtedness so
secured, together with all Attributable Debt (as defined below) in respect of
sale and leaseback transactions involving Principal Properties, would not exceed
15% of the Consolidated Net Assets (as defined below) of AES. This restriction
will not apply to, and there shall be excluded in computing secured indebtedness
for the purpose of such restriction, indebtedness secured by (a) property of any
Subsidiary of AES, (b) liens on property of, or on any shares of stock or debt
of, any corporation existing at the time such corporation becomes a Subsidiary,
(c) liens in favor of AES or any Subsidiary, (d) liens in favor of U.S. or
foreign governmental bodies to secure partial, progress, advance or other
payments, (e) liens

                                      S-10

on property, shares of stock or debt existing at the time of acquisition thereof
(including acquisition through merger or consolidation), purchase money
mortgages and construction cost mortgages existing at or incurred within 180
days of the time of acquisition thereof, (f) liens existing on the first date on
which any Senior Notes issued under the Indenture are authenticated by the
Trustee, (g) liens under one or more credit facilities for indebtedness in an
aggregate principal amount not to exceed $900 million at any time outstanding,
(h) liens incurred in connection with pollution control, industrial revenue or
similar financings, and (i) any extension, renewal or replacement of any debt
secured by any liens referred to in the foregoing clauses (a) through (h),
inclusive. As of the date of this prospectus supplement, AES does not own or
lease any Principal Property.

    The term "Principal Property" means any building, structure or other
facility (together with the land on which it is erected and fixtures comprising
a part thereof) used primarily for manufacturing, processing, research,
warehousing or distribution owned or leased by AES and having a net book value
in excess of 2% of Consolidated Net Assets, other than any such building,
structure or other facility or portion thereof which is a pollution control
facility financed by state or local governmental obligations or which the
principal executive officer, president and principal financial officer of AES
determine in good faith is not of material importance to the total business
conducted or assets owned by AES and its Subsidiaries as an entirety.

    The term "Consolidated Net Assets" means the aggregate amount of assets
(less reserves and other deductible items) after deducting current liabilities,
as shown on the consolidated balance sheet of AES and its Subsidiaries contained
in the latest annual report to the stockholders of AES and prepared in
accordance with generally accepted accounting principles.

    The term "Attributable Debt" means the present value (discounted at the rate
of 8.375% per annum compounded monthly) of the obligations for rental payments
required to be paid during the remaining term of any lease of more than 12
months.

    "Subsidiary" means, with respect to any person, any corporation, association
or other business entity of which a majority of the capital stock or other
ownership interests having ordinary voting power to elect a majority of the
board of directors or other persons performing similar functions are at the time
directly or indirectly owned by such person.

    RESTRICTIONS ON SALES AND LEASEBACKS. AES may not enter into any sale and
leaseback transaction involving any Principal Property, the acquisition or
completion of construction and commencement of full operation of which has
occurred more than 180 days prior thereto, unless (a) AES could incur a lien on
such property under the restrictions described above under "Restrictions on
Secured Debt" in an amount equal to the Attributable Debt with respect to the
sale and leaseback transaction without equally and ratably securing the Senior
Notes or (b) AES, within 180 days after the sale or transfer by AES, applies to
the retirement of its funded debt (defined as indebtedness for borrowed money
having a maturity of, or by its terms extendible or renewable for, a period of
more than 12 months after the date of determination of the amount thereof) an
amount equal to the greater of (i) the net proceeds of the sale of the Principal
Property sold and leased pursuant to such arrangement or (ii) the fair market
value of the Principal Property so sold and leased (subject to credits for
certain voluntary retirements of funded debt) as determined by the Board of
Directors of AES.

EVENTS OF DEFAULT

    In addition to the Events of Default set forth in the accompanying
prospectus, an Event of Default will occur with respect to the Senior Notes if
an event of default, as defined in any indenture or instrument evidencing or
under which AES has at the date of the Indenture or shall thereafter have
outstanding any indebtedness, shall happen and be continuing and either
(a) such default results from the failure to pay the principal of such
indebtedness

                                      S-11

in excess of $50 million at final maturity of such indebtedness or (b) as a
result of such default the maturity of such indebtedness shall have been
accelerated so that the same shall be or become due and payable prior to the
date on which the same would otherwise have become due and payable, and such
acceleration shall not be rescinded or annulled within 60 days and the principal
amount of such indebtedness, together with the principal amount of any other
indebtedness of AES in default, or the maturity of which has been accelerated,
aggregates $50 million or more; provided that the Trustee shall not be charged
with knowledge of any such default unless written notice thereof shall have been
given to the Trustee by AES, by the holder or an agent of the holder of any such
indebtedness, by the trustee then acting under any indenture or other instrument
under which such default shall have occurred, or by the holders of not less than
25% in the aggregate principal amount of the Senior Notes at the time
outstanding; and provided further that if such default shall be remedied or
cured by AES or waived by the holder of such indebtedness, then the Event of
Default under the Indenture by reason thereof shall be deemed likewise to have
been remedied, cured or waived without further action on the part of the
Trustee, any holder of Senior Notes or any other person.

DESCRIPTION OF BOOK-ENTRY SYSTEM

    GENERAL. We will issue the Senior Notes as one or more global securities
(each, a "Global Senior Note") registered in the name of Bank One, N.A., London
Branch, as common depositary (the "Common Depositary") for Clearstream Banking,
societe anonyme ("Clearstream") and Euroclear Bank S.A./N.V. (the "Euroclear
Operator"), as operator of the Euroclear System ("Euroclear"). Investors may
hold book-entry interests in the Global Senior Notes ("Book-Entry Interests")
through organizations that participate, directly or indirectly, in Clearstream
and/or Euroclear. Book-entry interests in the Senior Notes and all transfers
relating to the Senior Notes will be reflected only in the book-entry records of
Euroclear and Clearstream and, with respect to interests of indirect
participants, their respective participants. The laws of some countries and some
states in the United States may require that certain purchasers of securities
take physical delivery of such securities in definitive form. Such laws may
impair the ability to own, transfer or pledge the Book-Entry Interests. All
interests in the Senior Notes will be subject to the procedures and requirements
of Euroclear or Clearstream, as the case may be.

    So long as Euroclear or Clearstream or their nominee, or the Common
Depositary, as the case may be, is the registered holder of the Global Senior
Notes, such party will be considered the sole holder of such Global Senior Notes
for all purposes under the Indenture. Except as set forth below under
"--Certificated Notes," participants or indirect participants are not entitled
to have Senior Notes or Book-Entry Interests registered in their names, will not
receive or be entitled to receive physical delivery of Senior Notes or
Book-Entry Interests in definitive form and will not be considered the owners or
holders thereof under the Indenture. Accordingly, each person owning a
Book-Entry Interest must rely on the procedures of Euroclear or Clearstream, as
the case may be, and, if such person is not a participant in Euroclear or
Clearstream, as the case may be, on the procedures of the participant in
Euroclear or Clearstream, as the case may be, through which such person owns its
interest, to exercise any rights and remedies of a holder under the Indenture.
See "--Action by Owners of Book-Entry Interests" below. If any definitive Senior
Notes are issued to participants or indirect participants, they will be issued
in registered form ("definitive registered notes"), as described under
"--Certificated Notes." Unless and until Book-Entry Interests are exchanged for
definitive registered notes (as described under "--Certificated Notes") the
certificated depositary interests held by the Common Depositary may not be
transferred except as a whole by Euroclear or Clearstream to the Common
Depositary or by the Common Depositary to Euroclear or Clearstream,
respectively, or another nominee at Euroclear and Clearstream or by Euroclear
and Clearstream or any such nominee to a successor

                                      S-12

of Euroclear or Clearstream or a nominee of such successor.

    PAYMENTS ON THE GLOBAL NOTES. Payments of any amounts owing in respect of
the Global Senior Notes will be made through one or more paying agents (the
"Paying Agents") appointed under the Indenture (which initially will include the
Trustee). Payment to or to the order of the holder of the Global Senior Notes
shall discharge payment obligations in respect of the Senior Notes represented
thereby. Upon receipt of any such amounts, Euroclear or Clearstream, as the case
may be, should distribute such payments to its respective participants. Payments
of all such amounts will be made without deduction or withholding for or on
account of any present or future taxes, duties, assessments or governmental
charges of whatever nature except as may be required by law. If withholding for
taxes is required by law, such withholding will occur in accordance with
applicable law.

    Under the provisions of the Indenture, the registered holder of the Global
Senior Notes is treated as the owner of the Senior Notes represented thereby,
and the issuer has no responsibility or liability for the payment of amounts
owing in respect of the depositary interests held by the Common Depositary for
Euroclear and Clearstream to owners of Book-Entry Interests. Payments by
Euroclear or Clearstream participants to owners of Book-Entry Interests held
through such participants are the responsibility of such participants as is the
case with securities held for the account of customers in bearer form or
registered in "street name".

    None of AES, the Trustee or any agent of AES or the Trustee have any
responsibility or liability for any aspect of the records relating to or
payments made on account of Book-Entry Interests or for maintaining, supervising
or reviewing any records relating to such Book-Entry Interests.

    INFORMATION CONCERNING EUROCLEAR AND CLEARSTREAM. Clearstream advises that
it is incorporated under the laws of Luxembourg as a professional depositary.
Clearstream holds securities for its participating organizations ("Clearstream
Participants") and facilitates the clearance and settlement of securities
transactions between Clearstream Participants through electronic book-entry
changes in accounts of Clearstream Participants, thereby eliminating the need
for physical movement of certificates. Clearstream provides to Clearstream
Participants, among other things, services for safekeeping, administration,
clearance and settlement of internationally traded securities and securities
lending and borrowing. Clearstream interfaces with domestic markets in several
countries. As a professional depositary, Clearstream is subject to regulation by
the Luxembourg Monetary Institute. Clearstream Participants are recognized
financial institutions around the world, including underwriters, securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations and may include the underwriters. Indirect access to
Clearstream is also available to others, such as banks, brokers, dealers and
trust companies that clear through or maintain a custodial relationship with a
Clearstream Participant either directly or indirectly.

    Distributions with respect to the Senior Notes held beneficially through
Clearstream will be credited to cash accounts of Clearstream Participants in
accordance with its rules and procedures.

    Euroclear advises that it was created in 1968 to hold securities for
participants of Euroclear ("Euroclear Participants") and to clear and settle
transactions between Euroclear Participants through simultaneous electronic
book-entry delivery against payment, thereby eliminating the need for physical
movement of certificates and any risk from lack of simultaneous transfers of
securities and cash. Euroclear includes various other services, including
securities lending and borrowing and interfaces with domestic markets in several
countries. Euroclear is operated by Euroclear Bank S.A./ N.V (the "Euroclear
Operator"), under contract with Euroclear Clearance Systems S.C., a Belgian
Cooperative corporation (the "Cooperative"). All operations are conducted by the
Euroclear Operator, and all Euroclear securities clearance accounts and
Euroclear cash accounts are accounts with the Euroclear Operator, not the
Cooperative. The

                                      S-13

Cooperative establishes policy for Euroclear on behalf of Euroclear
Participants. Euroclear Participants include banks (including central banks),
securities brokers and dealers and other professional financial intermediaries
and may include the underwriters. Indirect access to Euroclear is also available
to other firms that clear through or maintain a custodial relationship with a
Euroclear Participant, either directly or indirectly.

    The Euroclear Operator was launched on December 31, 2000, and replaced
Morgan Guaranty Trust Company of New York as the operator of and banker to the
Euroclear System. Euroclear Bank S.A./N.V. has capital of approximately EUR 1
billion.

    Securities clearance accounts and cash accounts with the Euroclear Operator
are governed by the Terms and Conditions Governing Use of Euroclear and the
related Operating Procedures of the Euroclear System, and applicable Belgian law
(collectively, the "Terms and Conditions"). The Terms and Conditions govern
transfers of securities and cash within Euroclear, withdrawals of securities and
cash from Euroclear, and receipts of payments with respect to securities in
Euroclear. All securities in Euroclear are held on a fungible basis without
attribution of specific certificates to specific securities clearance accounts.
The Euroclear Operator acts under the Terms and Conditions only on behalf of
Euroclear Participants, and has no record of or relationship with persons
holding through Euroclear Participants.

    Distributions with respect to the Senior Notes held beneficially through
Euroclear will be credited to the cash accounts of Euroclear Participants in
accordance with the Terms and Conditions.

    ACTION BY OWNERS OF BOOK-ENTRY INTERESTS. As soon as practicable after
receipt by the Trustee of notice of any solicitation of consents or request for
a waiver or other action by the holders of Senior Notes, the Trustee will send
to Euroclear and Clearstream a notice containing (a) such information as is
contained in such notice received by the Trustee, (b) a statement that at the
close of business on a specified record date Euroclear and Clearstream will be
entitled to instruct the Trustee as to the consent, waiver or other action, if
any, pertaining to such Senior Notes and (c) a statement as to the manner in
which such instructions may be given. In addition, the Trustee will forward to
Euroclear and Clearstream, or, based upon instructions received from Euroclear
and Clearstream, to owners of Book-Entry Interests, all materials pertaining to
any such solicitation, request, offer or other action. Upon the written request
of Euroclear and Clearstream, as applicable, the Trustee shall endeavor insofar
as practicable to take such action regarding the requested consent, waiver,
offer, or other action in respect of such Senior Notes in accordance with any
instructions set forth in such request. Euroclear and Clearstream may grant
proxies or otherwise authorize their respective participants, or persons owning
Book-Entry Interests through their respective participants, to provide such
instructions to the Trustee so that it may exercise any rights of a holder or
take any other actions which a holder is entitled to take under the Indenture.
The Trustee will not exercise any discretion in the granting of consents or
waivers or the taking of any other action relating to the Indenture.

    REPORTS. The Trustee will immediately send to Euroclear and Clearstream a
copy of any notices, reports and other communications received relating to AES,
the Senior Notes or the Book-Entry Interests.

    SETTLEMENT. Any secondary market trading activity in the Book-Entry
Interests is expected to occur through the Euroclear Participants and
Clearstream Participants and the securities custody accounts of investors will
be credited with their holdings against payment in same-day funds on the
settlement date.

CERTIFICATED NOTES

    Each owner of a beneficial interest in the Global Senior Note will receive a
definitive registered note (i) if Euroclear and Clearstream notify us that they
are unwilling or unable to act as clearing agency and a successor is not
appointed by us within 90 days or (ii) if we, in our sole discretion, at any
time determine not to

                                      S-14

have the Senior Notes represented by a Global Senior Note. In the event
definitive notes are issued, we will promptly provide notice to the holders of
the Senior Notes.

    Any definitive registered note will be issued in registered form in
denominations of L1,000 principal amount or multiple thereof. Any definitive
registered note will be registered in such name or names as the Common
Depositary shall be instructed based on the instructions of Euroclear or
Clearstream. It is expected that such instructions will be based upon directions
received by Euroclear or Clearstream from their participants with respect to
ownership of Book-Entry Interests. To the extent permitted by law, AES, the
Common Depositary and any paying agent shall be entitled to treat the person in
whose name any definitive registered note is registered as the absolute owner
thereof. The amount of the relevant Global Senior Notes, and the Book-Entry
Interests, will be increased or decreased to reflect exchanges or issues of
definitive registered notes. The Common Depositary will make the appropriate
adjustments to the Global Senior Note or Notes underlying the Book-Entry
Interests to reflect any such issues or adjustments. The Indenture contains
provisions relating to the maintenance by a registrar of a register reflecting
ownership of definitive registered notes, if any, and other provisions customary
for a registered debt security. Payment of principal and interest on, and all
other amounts payable under, each definitive registered note will be made to the
holder appearing on the register at the close of business on the record date at
his address shown on the register on the record date.

    In the event individual certificates for the Senior Notes are issued, the
holders of such Senior Notes will be able to receive payment on the Senior Notes
and effect transfers of the Senior Notes at the offices of the Luxembourg paying
agent and transfer agent. We have appointed Banque Internationale a Luxembourg
S.A. as paying agent and transfer agent in Luxembourg with respect to the Senior
Notes in individual certificated form, and as long as the Senior Notes are
listed on the Luxembourg Stock Exchange, we will maintain a paying agent in
Luxembourg. In the event individual certificates for the Senior Notes are issued
in definitive form, principal of, premium, if any, and interest on the Senior
Notes will be payable, and the Senior Notes will be exchangeable and
transferable, as described below, and so long as the Senior Notes are listed on
the Luxembourg Stock Exchange, at the offices of the paying agent in Luxembourg.

    We have also appointed Bank One, N.A., London Branch, as principal paying
agent.

    Unless and until we issue the Senior Notes in fully certificated, registered
form, (1) you will not be entitled to receive a certificate representing your
interest in the Senior Notes; (2) all references in this prospectus supplement
or in the accompanying prospectus to actions by holders will refer to actions
taken by the Common Depositary upon instructions from Euroclear and Clearstream;
and (3) all references in this prospectus supplement or in the accompanying
prospectus to payments and notices to holders will refer to payments and notices
to the Common Depositary, as the registered holder of the Senior Notes, for
distribution to you in accordance with its policies and procedures.

    The cost of preparing, printing, packaging and delivering a definitive
registered note will be solely the responsibility of AES.

    Principal of and interest on, and all other amounts payable under, any
definitive registered notes will be payable at the office of the paying agent in
Luxembourg maintained for such purposes. The relevant definitive registered note
must be surrendered at the office of the paying agent in Luxembourg to receive
payments of principal. In addition, interest on definitive registered notes may
be paid by check mailed to the person entitled thereto as shown on the register
on the record date for the definitive registered notes. If a payment date is not
a business day at a place of payment, payment may be made at that place on the
next succeeding business day and no interest shall accrue for the intervening
period.

    Transfers of any definitive registered note may be made, by presenting and
surrendering such note at the office of any transfer agent. Transfers of a
portion of a definitive registered

                                      S-15

note may be made in authorized denominations of L1,000 at the office of any
transfer agent and new definitive registered notes in appropriate denominations
will be made available by the issuer at such office. No service charge will be
made for any registration of transfer or exchange of any definitive registered
notes but the trustee may require payment of a sum sufficient to cover any tax
or other governmental change payable in connection therewith.

    All Senior Notes will be recorded in a register maintained by the Common
Depositary, and will be registered in the name of Clearstream or Euroclear for
the benefit of owners of beneficial interests in the Global Senior Notes.

PAYMENTS OF PRINCIPAL AND INTEREST; TRANSFER OR EXCHANGE

    The Indenture will require that payments in respect of the Senior Notes
(including principal, premium, if any, and interest) held of record by the
Common Depositary, Clearstream or Euroclear, as the case may be, be made in same
day funds. Payments in respect of the Senior Notes held of record by holders
other than the Common Depositary, Clearstream or Euroclear, as the case may be,
may at the option of AES, be made by check and mailed to such holders of record
as shown on the register for the Senior Notes.

    All transfers of Book-Entry Interests are recorded in accordance with the
book-entry system maintained by Euroclear or Clearstream, as applicable,
pursuant to customary procedures established by each respective system and its
participants. While a Global Senior Note is outstanding, holders of definitive
registered notes may exchange their definitive registered notes for Book-Entry
Interests in the applicable Global Senior Notes by surrendering their definitive
registered notes to the Trustee or to the paying and transfer agent in
Luxembourg. The amount of the Book-Entry Interests will be increased or
decreased to reflect such transfers or exchanges. The Trustee or the paying and
transfer agent in Luxembourg, as applicable, will make the appropriate
adjustments to the applicable Global Senior Note or exchange such Global Senior
Note for a new Global Senior Note in an appropriate principal amount to reflect
any such transfers or exchanges.

SUBSTITUTION OF CURRENCY

    Principal of and interest on, and all other amounts payable under, any
definitive registered notes will be payable at the corporate trust office or
agency of the Trustee in The City of New York and at the office of the paying
and transfer agent in London and Luxembourg maintained for such purposes. The
relevant definitive registered note must be surrendered at the office of the
Trustee in New York City or at the office of the paying and transfer agent in
London and Luxembourg to receive payments of principal. Pursuant to the Treaty
establishing the European Community, as amended by the Treaty on European Union,
signed at Maastricht on February 7, 1992, the Euro was introduced on January 1,
1999 in substitution for the national currencies of eleven member states of the
European Union. Although the United Kingdom government exercised its opt-out and
is not participating in the introduction of the Euro, the United Kingdom
government has stated that the United Kingdom might wish to join the single
currency at a later date. If the United Kingdom adopts the Euro, the regulations
of the European Commission relating to the Euro shall apply to the Senior Notes.
In accordance with the Indenture and the laws of the State of New York, none of
the foregoing will entitle either us or any holder of Senior Notes to early
redemption, rescission, notice or repudiation of the terms and conditions of the
Senior Notes or the Indenture or to raise other defenses or to request any
compensation claim, nor will they affect any of our other obligations under the
Senior Notes and the Indenture.

GOVERNING LAW AND JURISDICTION

    The Indenture and Senior Notes will be governed by and construed in
accordance with the laws of the State of New York, without giving effect to such
state's conflict of laws principles.

    We will submit to the jurisdiction of the United States Federal and New York
State courts located in the City of New York for all

                                      S-16

purposes of or in connection with the Indenture and the Senior Notes, as the
case may be.

NOTICES

    Notices to holders of the Senior Notes will be published in authorized
newspapers in The City of New York, in London, and, so long as such Senior Notes
are listed on the Luxembourg Stock Exchange and the rules of that exchange so
require, in a leading newspaper having general circulation in Luxembourg. It is
expected that publication will be made in The City of New York in THE WALL
STREET JOURNAL, in London in the FINANCIAL TIMES and in Luxembourg in the
LUXEMBURGER WORT. Any such notice shall be deemed to have been given on the date
of such publication or, if published more than once, on the date of the first
such publication.

INFORMATION CONCERNING THE TRUSTEE

    AES and its subsidiaries may maintain deposit accounts and conduct other
banking transactions with the Trustee in the ordinary course of business.

OTHER PROVISIONS

    See the accompanying prospectus for a description of certain additional
provisions of the Indenture, including events of default thereunder and
provisions for amendments and modifications thereof.

                                      S-17

                 CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

    The following is a general discussion of certain U.S. federal income tax
consequences of the ownership and disposition of Senior Notes to an initial
holder purchasing a Senior Note at its "issue price" in this offering and
holding the Senior Note as a capital asset within the meaning of Section 1221 of
the Code (as defined below). The "issue price" is the first price to the public
at which a substantial amount of the Senior Notes is sold for money (excluding
sales to bond houses, brokers or similar persons or organizations acting in the
capacity of underwriters, placement agents or wholesalers).

    This discussion is based on the Internal Revenue Code of 1986, as amended
(the "Code"), Treasury Regulations, judicial interpretations and administrative
interpretations as of the date hereof, all of which are subject to change,
including changes with retroactive effect. This discussion does not address all
aspects of U.S. federal income taxation that may be relevant to holders in light
of their particular circumstances or to holders subject to special rules, such
as certain financial institutions, insurance companies, dealers and certain
traders in securities, persons holding Senior Notes in connection with a hedging
transaction, "straddle", conversion transaction or other integrated transaction,
or persons who have ceased to be United States citizens or to be taxed as
resident aliens. This discussion does not address the tax consequences to
partnerships or other pass-through entities or persons investing through such
partnerships or entities. This discussion does not address any tax consequences
arising under the laws of any state, local or foreign jurisdiction. Prospective
holders should consult their tax advisers with respect to the particular tax
consequences to them of owning and disposing of Senior Notes, including the
consequences under the laws of any state, local or foreign jurisdiction.

    "U.S. Holder" means an owner of a Senior Note that is, for U.S. federal
income tax purposes, (i) a citizen or resident alien individual of the United
States, (ii) a corporation or other entity taxed as a corporation for federal
income tax purposes created or organized in or under the laws of the United
States or of any political subdivision thereof or (iii) an estate or trust the
income of which is subject to U.S. federal income taxation regardless of its
source.

    "Non-U.S. Holder" means an owner of a Senior Note that is, for U.S. federal
income tax purposes, a non-resident alien individual, a foreign corporation or a
non-resident alien fiduciary of a foreign estate or trust.

    Assuming that the Senior Notes are "publicly traded" within the meaning of
the applicable Treasury Regulations, the Senior Notes will be treated as part of
the same issue as the Senior Notes issued on February 22, 2001 (the "original
Senior Notes"). As a result, the Senior Notes will have the same issue date and
the same issue price as the original Senior Notes.

U.S. HOLDERS

    A U.S. Holder who uses the cash method of accounting will be required to
include in income the U.S. dollar value of the foreign currency interest payment
(determined on the date the payment is received) regardless of whether the
payment is in fact converted to U.S. dollars at that time, and this U.S. dollar
value will be the U.S. Holder's tax basis in the foreign currency.

    In the case of an accrual method taxpayer, a U.S. Holder will be required to
include in income the U.S. dollar value of the amount of interest income that
has accrued and is otherwise required to be taken into account with respect to a
Senior Note during an accrual period. The U.S. dollar value of the accrued
income will be determined by translating the income at the average rate of
exchange for the accrual period or, with respect to an accrual period that spans
two taxable years, at the average rate for the partial period within the taxable
year. The U.S. Holder will recognize ordinary income or loss with respect to
accrued interest income on the date such income is actually received (including
a payment attributable to accrued but unpaid interest upon the sale, exchange or
retirement of a Senior Note). The amount of ordinary income or loss

                                      S-18

recognized will equal the difference between the U.S. dollar value of the
foreign currency payment received (determined on the date the payment is
received) in respect of the accrual period and the U.S. dollar value of interest
income that has accrued during such accrual period (as determined above).

    A U.S. Holder may elect to translate interest income into U.S. dollars at
the spot rate on the last day of the interest accrual period (or, in the case of
an accrual period that spans two taxable years, at the exchange rate in effect
on the last day of the partial period within the taxable year) or, if the date
of receipt is within five business days of the last day of the interest accrual
period or taxable year, the spot rate on the date of receipt. A U.S. Holder that
makes such an election must apply it consistently to all debt instruments held
by the U.S. Holder at the beginning of the first taxable year to which the
election applies or thereafter acquired by such U.S. Holder and cannot change
the election without the consent of the Internal Revenue Service.

    A U.S. Holder's tax basis in a Senior Note will be the U.S. dollar value of
the foreign currency amount paid for such Senior Note determined on the date of
such purchase. A U.S. Holder who purchases a Senior Note with previously owned
foreign currency will recognize ordinary income or loss in an amount equal to
the difference, if any, between such U.S. Holder's tax basis in the foreign
currency and the U.S. dollar fair market value of the Senior Note on the date of
purchase.

    Gain or loss realized upon the sale, exchange or retirement of a Senior Note
that is attributable to fluctuations in currency exchange rates will be ordinary
income or loss which will not be treated as interest income or expense. With
respect to a U.S. Holder who uses the cash method of accounting, gain or loss
attributable to fluctuations in exchange rates will equal the difference between
(i) the U.S. dollar value of the foreign currency principal amount of the Senior
Note determined on the date such payment is received or the note is disposed of,
and (ii) the U.S. dollar value of the foreign currency principal amount of the
Senior Note determined on the date the U.S. Holder acquired the Senior Note. In
the case of an accrual method taxpayer, gain or loss attributable to
fluctuations in exchange rates will equal the difference between (i) the U.S.
dollar value of the foreign currency principal amount of the Senior Note and any
payment with respect to accrued interest, determined on the date such payment is
received or the note is disposed of, and (ii) the U.S. dollar value of the
foreign currency principal amount of the Senior Note, determined on the date the
U.S. Holder acquired the Senior Note, and the U.S. dollar value of the accrued
interest received, determined by translating such interest at the average
exchange rate for the accrual period. The foreign currency gain or loss will be
recognized only to the extent of the total gain or loss realized by a U.S.
Holder on the sale, exchange or retirement of the Senior Note. The source of the
foreign currency gain or loss will be determined by reference to the residence
of the U.S. Holder or the "qualified business unit" of the U.S. Holder on whose
books the Senior Note is properly reflected. Any gain or loss realized by such a
holder in excess of the foreign currency gain or loss will be capital gain or
loss.

NON-U.S. HOLDERS

    Under present United States federal tax law, and subject to the discussion
below concerning backup withholding:

    (a) payments of principal, interest and premium on the Senior Notes by AES
or its paying agent to any Non-U.S. Holder will be exempt from the 30% U.S.
federal withholding tax, provided that (i) such Non-U.S. Holder does not own,
actually or constructively, 10% or more of the total combined voting power of
all classes of our stock entitled to vote and is not a controlled foreign
corporation related, directly or indirectly, to us through stock ownership and
(ii) the statement requirement set forth in Section 871(h) or Section 881(c) of
the Code has been fulfilled with respect to the beneficial owner, as discussed
below; and

    (b) a Non-U.S. Holder of a Senior Note will not be subject to U.S. federal
income tax on gain realized on the sale, retirement or other

                                      S-19

taxable disposition of such Senior Note, unless such gain is effectively
connected with the Holder's conduct of a trade or business in the United States.

    The certification requirement referred to in subparagraph (a) will be
fulfilled if the beneficial owner of a Senior Note certifies on Internal Revenue
Service ("IRS") Form W-8BEN, under penalties of perjury, that it is not a United
States person and provides its name and address, and (i) such beneficial owner
files such Form W-8BEN with the withholding agent or (ii) in the case of a
Senior Note held by a securities clearing organization, bank or other financial
institution holding customers' securities in the ordinary course of its trade or
business holding the Senior Note on behalf of the beneficial owner, such
financial institution files with the withholding agent a statement that it has
received the Form W-8BEN from the Holder and furnishes the withholding agent
with a copy thereof. Prospective investors, including foreign partnerships and
their partners, should consult their tax advisers regarding possible additional
reporting requirements.

    If a Non-U.S. Holder of a Senior Note is engaged in a trade or business in
the United States, and if interest on the Senior Note (or gain realized on its
sale, exchange or other disposition) is effectively connected with the conduct
of such trade or business, the Non-U.S. Holder, although exempt from the
withholding tax discussed in the preceding paragraphs, will generally be subject
to regular U.S. federal income tax on such effectively connected income in the
same manner as if it were a U.S. Holder. See "--U.S. Holders" above. In lieu of
the certificate described in the preceding paragraph, such a Holder will be
required to provide to the withholding agent a properly executed IRS Form W-8ECI
to claim an exemption from withholding tax. In addition, if such Non-U.S. Holder
is a foreign corporation, it may be subject to a 30% branch profits tax (unless
reduced or eliminated by an applicable treaty) on its earnings and profits for
the taxable year attributable to such effectively connected income, subject to
certain adjustments.

BACKUP WITHHOLDING AND INFORMATION REPORTING

    Information returns will be filed with the Internal Revenue Service in
connection with payments on the Notes and the proceeds from a sale or other
disposition of the Notes. If you are a U.S. Holder, you will be subject to a 31%
United States backup withholding tax on these payments unless you provide your
taxpayer identification number to the paying agent and comply with certain
certification procedures or otherwise establish an exemption from backup
withholding. If you are a Non-U.S. Holder, you may have to comply with
certification procedures to establish that you are not a United States person in
order to avoid information reporting and backup withholding tax requirements.
The certification on Form W-8BEN, required to claim exemption from 30% federal
withholding on interest payments as described above, will satisfy the
certification requirements necessary to avoid the 31% backup withholding tax as
well.

    The amount of any backup withholding from a payment to you will be allowed
as a credit against your United States federal income tax liability and may
entitle you to a refund, provided that the required information is furnished to
the Internal Revenue Service.

                          GENERAL LISTING INFORMATION

    The Senior Notes have been accepted for clearance through Euroclear and
Clearstream under Common Code No. 012516878. The ISIN for the Senior Notes is
XS0125168780.

    Application has been made to list the Senior Notes on the Luxembourg Stock
Exchange. The certified Certificate of Incorporation of AES and the legal notice
relating to the issue of the Senior Notes will be deposited prior to any listing
with the Chief Registrar of the District Court in Luxembourg (GREFFIER EN CHEF
DU TRIBUNAL D'ARRONDISSEMENT A LUXEMBOURG), where such documents are available
for inspection and where copies thereof can be obtained upon request. As long as
the Senior Notes are listed on the Luxembourg Stock Exchange, an agent for
making payments on, and transfers of, Senior Notes will be maintained in
Luxembourg.

    The consolidated financial statements of AES as of December 31, 1998 and
1999, and for each of the three years in the period ended December 31, 1999 have
been prepared in accordance with United States generally accepted accounting
principles and have been audited by Deloitte & Touche LLP in accordance with
United States generally accepted auditing standards. On May 26, 2000,
Deloitte & Touche LLP gave consent to the incorporation by reference in the
Registration Statement (Form S-3 No. 333-37924) and related prospectus of AES,
of their reports dated February 3, 2000 (February 22, 2000 as to the last
paragraph of Note 2) with respect to the consolidated financial statements of
AES.

    For so long as the Senior Notes are listed on the Luxembourg Stock Exchange
and the rules of such exchange so require, copies of the following documents may
be inspected at the specified office of the paying and transfer agent in
Luxembourg:

    - Certified Certificate of Incorporation of AES;

    - paying agency agreement;

    - the Indenture relating to the Senior Notes, which include the forms of the
      Senior Note certificates.

    In addition, copies of the most recent annual audited consolidated financial
statements of AES for the preceding financial year, and any interim unaudited
consolidated quarterly financial statements published by AES, will be available
for collection at the specified office of the Paying Agent in Luxembourg for so
long as the Senior Notes are listed on the Luxembourg Stock Exchange and the
rules of such exchange so require. AES publishes only audited annual and
unaudited quarterly financial statements on a consolidated basis.

    Except as disclosed in this document, AES represents that there has been no
material adverse change in its financial position since December 31, 1999.

    Except as disclosed in this document, AES is not involved in any litigation
or arbitration proceedings relating to claims or amounts which are material in
the context of the issue of the Senior Notes nor, so far as AES is aware, is any
such litigation or arbitration pending or threatened.

    The issuance of the Senior Notes was authorized by resolutions adopted by
the AES Board of Directors on April 21, 1998 and May 30, 2000 and resolutions
adopted by the AES Offering Committee on April 27, 2001.

    AES has confirmed that it:

    (a) has complied with, and will comply with, its obligations under the
relevant rules in relation to the admission to listing of the Senior Notes by
the time such Senior Notes are so admitted; and

    (b) having made all reasonable inquiries, has not become aware of any change
in circumstances which could reasonably be regarded as significantly and
adversely affecting its ability to meet its obligations as issuer in respect of
the Senior Notes as they fall due.

                                      S-21

                                  UNDERWRITING

    Subject to the terms and conditions stated in the underwriting agreement
dated April 27, 2001, Salomon Brothers International Limited has agreed to
purchase, and AES has agreed to sell to such underwriter, L50,000,000 aggregate
principal amount of Senior Notes.

    The underwriting agreement provides that the obligations of the underwriter
to purchase the Senior Notes included in this offering are subject to approval
of certain legal matters by counsel and to certain other conditions. The
underwriter is obligated to purchase all the Senior Notes if it purchases any of
the Senior Notes.

    The underwriter has advised AES that it proposes to offer some of the Senior
Notes directly to the public at the public offering price set forth on the cover
page of this prospectus supplement and some of the Senior Notes to certain
dealers at the public offering price less a concession not in excess of 0.50% of
the principal amount of the Senior Notes. The underwriter may allow, and such
dealers may reallow, a concession not in excess of 0.25% of the principal amount
of the Senior Notes on sales to certain other dealers. After the initial
offering of the Senior Notes to the public, the public offering price and such
concessions may be changed by the underwriter.

    The following table shows the underwriting discounts and commissions to be
paid to the underwriter by AES in connection with this offering (expressed as a
percentage of the principal amount of the Senior Notes).



                                  PAID BY AES
                                  -----------
                               
Per Senior Note.................      1.50%


    In connection with this offering, the underwriter may over-allot, or engage
in covering and stabilizing transactions. Over-allotment involves sales of
Senior Notes in excess of the principal amount of Senior Notes to be purchased
by the underwriter in this offering, which creates a short position. Covering
transactions involve purchases of the Senior Notes in the open market after the
distribution has been completed in order to cover short positions. Stabilizing
transactions consist of certain bids on purchases of Senior Notes made for the
purposes of preventing or retarding a decline in the market price of the Senior
Notes while the offering is in progress. These activities may cause the price of
the Senior Notes to be higher than the price that otherwise would exist in the
open market in the absence of such transactions. These transactions may be
effected in the over-the-counter market or otherwise and, if commenced, may be
discontinued at any time.

    We have applied for the Senior Notes to be listed on the Luxembourg Stock
Exchange in accordance with the rules thereof.

    The underwriter has agreed that: (i) it has not offered or sold, and before
the date six months after the date of issue of the Senior Notes will not offer
or sell, any Senior Notes to persons in the United Kingdom except to persons
whose ordinary activities involve them in acquiring, holding, managing or
disposing of investments (as principal or agent) for purposes of their
businesses or otherwise in circumstances which have not resulted and will not
result in an offer to the public in the United Kingdom within the meaning of the
Public Offers of Securities Regulations 1995, as amended; (ii) it has complied,
and will comply, with all applicable provisions of the United Kingdom Financial
Services Act 1986, as amended, and the Public Offers of Securities Regulations
1995, as amended, with respect to anything done by it in relation to the Senior
Notes in, from or otherwise involving the United Kingdom; and (iii) it has only
issued or passed on, and will only issue or pass on, in the United Kingdom any
document received by it in connection with the issuance of the Senior Notes to a
person who is of a kind described in Article 11(3) of the Financial Services Act
1986 (Investment Advertisements) (Exemptions) Order 1996 (as amended) or is a
person to whom the document may otherwise lawfully be issued or passed on.

    AES estimates that its total expenses of this offering will be $200,000.

                                      S-22

    In the ordinary course of the underwriter's business, the underwriter and
its affiliates have engaged and may engage in commercial and investment banking
transactions with AES and its affiliates.

                                 LEGAL MATTERS

thereto will be passed upon for us by Davis Polk & Wardwell, New York, New York.

                                  RISK FACTORS

    PURCHASERS OF THE SECURITIES SHOULD READ THIS ENTIRE PROSPECTUS CAREFULLY.
OWNERSHIP OF THE SECURITIES INVOLVES CERTAIN RISKS. THE FOLLOWING FACTORS SHOULD
BE CONSIDERED CAREFULLY IN EVALUATING AES AND ITS BUSINESS BEFORE PURCHASING THE
SECURITIES OFFERED BY THIS PROSPECTUS.

    OUR HIGH DEGREE OF LEVERAGE COULD AFFECT OUR ABILITY TO FULFILL OUR
OBLIGATIONS UNDER OUR SECURITIES. We had approximately $13,715 million of
outstanding indebtedness at March 31, 2000. As a result, we might be
significantly limited in our ability to meet our debt service obligations, to
finance the acquisition, development or completion of additional projects, to
compete effectively or to operate successfully under adverse economic
conditions. As of March 31, 2000, we had a consolidated ratio of total debt to
total book capitalization (including current debt) of approximately 72%.

    HOLDERS OF OUR DEBT SECURITIES WILL BE SUBORDINATED TO MANY OF OUR OTHER
CREDITORS.  The Senior Subordinated Debt Securities will be subordinated to all
Senior Debt, including, but not limited to, the amounts outstanding under our
current $850 million revolving credit facility. The Junior Subordinated Debt
Securities will be subordinated to all of our Senior and Senior Subordinated
Debt, including, but not limited to, the amounts outstanding under our current
$850 million revolving credit facility. As of March 31, 2000, we had
approximately $1,581 million in aggregate principal amount of Senior Debt (which
includes $346 million of letters of credit) and $2,656 million in aggregate
principal amount of Senior and Senior Subordinated Debt.

    Upon any payment or distribution of assets to creditors upon any
liquidation, dissolution, winding up, receivership, reorganization, assignment
for the benefit of creditors, marshaling of assets and liabilities or any
bankruptcy, insolvency or similar proceedings, the holders of Senior Debt will
be entitled to receive payment in full of all amounts due under all Senior Debt
before the holders of the Senior Subordinated Debt Securities will be entitled
to receive any payment in respect of the Senior Subordinated Debt Securities;
holders of Senior and Senior Subordinated Debt will be entitled to receive
payment in full of all amounts due under all Senior and Senior Subordinated Debt
before the holders of the Junior Subordinated Debt Securities will be entitled
to receive any payment in respect of the Junior Subordinated Debt Securities.

    No payments in respect of the Senior Subordinated Debt Securities or Junior
Subordinated Debt Securities may be made

    - if a default has occurred and is continuing in a payment under the Senior
      Debt or Senior and Senior Subordinated Debt, respectively, or

    - during certain periods when an event of default under certain Senior Debt
      or Senior and Senior Subordinated Debt, respectively, permits the
      respective lenders thereunder to accelerate the maturity thereof.

    See "Description of Debt Securities--Subordination of Senior Subordinated
Debt Securities" and "Description of Debt Securities--Subordination of Junior
Subordinated Debt Securities."

    The Debt Securities will be effectively subordinated to the indebtedness and
other obligations (including trade payables) of our subsidiaries. At March 31,
2000, the indebtedness and obligations of our subsidiaries aggregated
approximately $13,335 million. Our ability to pay principal of, premium, if any,
and interest on the Debt Securities will be dependent upon the receipt of funds
from our subsidiaries by way of dividends, fees, interest, loans or otherwise.
Most of our subsidiaries with interests in power generation facilities currently
are obligated, pursuant to loan agreements or indentures, to satisfy certain
restricted payment covenants before they may make distributions to us. Moreover,
unless otherwise provided in the prospectus supplement, the Indentures for the
Debt Securities will permit our subsidiaries to maintain or add to such
restrictions. Our subsidiaries are separate and distinct legal

                                       3

entities and have no obligation, contingent or otherwise, to pay any amounts due
pursuant to the Debt 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 Debt Securities. Any right we have to receive
any assets of any of our subsidiaries upon any liquidation, dissolution, winding
up, receivership, reorganization, assignment for the benefit of creditors,
marshaling of assets and liabilities or any bankruptcy, insolvency or similar
proceedings (and the consequent right of the holders of the Debt Securities to
participate in the distribution of, or to realize proceeds from, those assets)
will be effectively subordinated to the claims of any such subsidiary's
creditors (including trade creditors and holders of debt issued by such
subsidiary).

    WE DO A SIGNIFICANT AMOUNT OF OUR BUSINESS OUTSIDE THE UNITED STATES WHICH
PRESENTS SIGNIFICANT RISKS.  Our involvement in the development of new
businesses and the acquisition of existing plants in locations outside the
United States is increasing and a large portion of our current development and
acquisition activities are for projects and plants outside the United States.

    The financing, development and operation of projects outside the United
States entail significant political and financial uncertainties (including,
without limitation, uncertainties associated with first-time privatization
efforts in the countries involved, currency exchange rate fluctuations, currency
repatriation restrictions, regulation of the electricity business, currency
inconvertibility, tax law, political instability, civil unrest, and
expropriation) and other credit quality, liquidity or structuring issues that
have the potential to cause substantial delays in respect of or material
impairment of the value of the project being developed or operated, which we may
not be capable of fully insuring or hedging against. The ability to obtain
financing on a commercially acceptable non-recourse basis in developing nations
has become more difficult. Even when such non-recourse financing is available,
lenders may require us to make higher equity investments than historically have
been the case. In addition, financing in countries with less than investment
grade sovereign credit ratings may also require substantial participation by
multilateral financing agencies. There can be no assurance that such financing
can be obtained when needed.

    The uncertainty of the legal environment in certain countries in which we
are or in the future may be developing, constructing or operating could make it
more difficult for us to enforce our respective rights under agreements relating
to such businesses. In addition, the laws and regulations of certain countries
may limit our ability to hold a majority interest in some of the businesses that
we may develop or acquire. International businesses we own may, in certain
cases, be expropriated by applicable governments. Although we may have legal
recourse in enforcing our rights under agreements and recovering damages for
breaches thereof, there can be no assurance that any such legal proceedings will
be successful or resolved in a timely manner.

    GLOBAL COMPETITION IS INCREASING AND COULD ADVERSELY AFFECT US.  The global
power production market is characterized by numerous strong and capable
competitors, many of whom may have extensive and diversified developmental or
operating experience (including both domestic and international experience) and
financial resources similar to or greater than ours. Further, in recent years,
the power production industry has been characterized by strong and increasing
competition with respect to both obtaining power sales agreements and acquiring
existing power generation assets. In certain markets, these factors have caused
reductions in prices contained in new power sales agreements and, in many cases,
have caused higher acquisition prices for existing assets through competitive
bidding practices. The evolution of competitive electricity markets and the
development of highly efficient gas-fired power plants have also caused, or are
anticipated to cause, price pressure in certain power markets where we sell or
intend to sell power. There can be no assurance that the foregoing competitive
factors will not have a material adverse effect on us.

    DEVELOPMENT UNCERTAINTIES.  The majority of the projects that we develop are
large and

                                       4

complex and the completion of any such project is subject to substantial risks.
Development can require us to expend significant sums for preliminary
engineering, permitting, legal and other expenses in preparation for competitive
bids which we may not win or before it can be determined whether a project is
feasible, economically attractive or capable of being financed. Successful
development and construction is contingent upon, among other things, negotiation
of satisfactory engineering, construction, fuel supply and power sales contracts
with other project participants, receipt of required governmental permits and
consents and timely implementation and satisfactory completion of construction.
There can be no assurance that we will be able to obtain new power sales
contracts, overcome local opposition, if any, obtain the necessary site
agreements, fuel supply and ash disposal agreements, construction contracts,
steam sales contracts, licenses and certifications, environmental and other
permits and financing commitments necessary for the successful development of
our projects. There can be no assurance that development efforts on any
particular project, or our efforts generally, will be successful. If these
development efforts are not successful, we may abandon a project under
development. At the time of abandonment, we would expense all capitalized
development costs incurred in connection therewith and could incur additional
losses associated with any related contingent liabilities. Our future growth is
dependent, in part, upon the demand for significant amounts of additional
electrical generating capacity and our ability to obtain contracts to supply
portions of this capacity. Any material unremedied delay in, or unsatisfactory
completion of, construction of our projects could, under certain circumstances,
have an adverse effect on our ability to meet our obligations, including the
payment of principal of, premium, if any, and interest on Debt Securities. We
may also be faced with certain development uncertainties arising out of doing
business outside of the United States. See "--We do a significant amount of our
business outside the United States which presents significant risks."

    OUR ACQUISITIONS MAY NOT PERFORM AS EXPECTED. We have achieved a majority of
our growth through acquisitions and expect that we will continue to grow, in
part, through acquisitions. Although each of the acquired businesses had a
significant operating history at the time we acquired them, we have a limited
history of owning and operating many of these businesses. In addition, most of
these businesses were government owned and some were operated as part of a
larger integrated utility prior to their acquisition. There can be no assurances
that we will be successful in transitioning these to private ownership, that
such businesses will perform as expected or that the returns from such
businesses will support the indebtedness incurred to acquire them or the capital
expenditures needed to develop them.

    WE MAY NOT BE ABLE TO RAISE SUFFICIENT CAPITAL TO FUND ACQUISITIONS AND
GREENFIELD PROJECTS OR REFINANCE EXISTING DEBT.  Each of our projects under
development and those independent power facilities we have committed to acquire
or may seek to acquire may require substantial capital investment. Continued
access to capital with acceptable terms is necessary to assure the success of
future projects and acquisitions, and may be necessary to refinance certain
existing debt. We have utilized project financing loans to fund the capital
expenditures associated with constructing and acquiring our electric power
plants and related assets to the extent possible. Project financing borrowings
have been substantially non-recourse to our other subsidiaries and affiliates
and to us as the parent company and are generally secured by the capital stock,
physical assets, contracts and cash flow of the related project subsidiary or
affiliate. We intend to continue to seek, where possible, such non-recourse
project financing. However, depending on market conditions and the unique
characteristics of individual projects, such financing may not be available or
our traditional providers of project financing, particularly multinational
commercial banks, may seek higher borrowing spreads and increased equity
contributions.

                                       5

    Furthermore, because of the reluctance of commercial lending institutions to
provide non-recourse project financing (including financial guarantees) in
certain less developed economies, we have sought and will continue to seek, in
such locations, direct or indirect (through credit support or guarantees)
project financing from a limited number of multilateral or bilateral
international financial institutions or agencies. As a precondition to making
such project financing available, these institutions may also require
governmental guarantees of certain project and sovereign related risks.
Depending on the policies of specific governments, such guarantees may not be
offered and as a result, we may determine that sufficient financing will
ultimately not be available to fund the related project. In addition, we are
frequently required to provide more sponsor equity for projects that sell their
electricity into the merchant market than for projects that sell their
electricity under long term contracts.

    In addition to the project financing loans, if available, we provide a
portion, or in certain instances all, of the remaining long-term financing
required to fund development, construction, or acquisition. These investments
have generally taken the form of equity investments or loans, which are
subordinated to the project financing loans. The funds for these investments
have been provided by cash flows from operations and by the proceeds from
borrowings under our short-term credit facilities and issuances of senior notes,
senior subordinated notes, convertible debentures, convertible trust preferred
securities and common stock.

    Our ability to arrange for financing on either a fully recourse or a
substantially non-recourse basis and the costs of such capital are dependent on
numerous factors, including general economic and capital market conditions, the
availability of bank credit, rating agency ratings, investor confidence, the
continued success of current projects and provisions of tax and securities laws
which are conducive to raising capital in this manner. Should future access to
capital not be available, we may decide not to build new plants or acquire
existing facilities. While a decision not to build new plants or acquire
existing facilities would not affect the results of operations of our currently
operating facilities or facilities under construction, such a decision would
affect our future growth.

    THE PERFORMANCE OF OUR GENERATION BUSINESS IS DEPENDENT TO A LARGE DEGREE ON
CERTAIN OF OUR LARGER PROJECTS AND THEIR CUSTOMERS.  The nature of most of our
generation plants (based on revenues) is such that each facility generally
relies on one power sales contract with a single customer for the majority, if
not all, of its revenues over the life of the power sales contract. The
prolonged failure of any significant customer to fulfill its contractual
obligations could have a substantial negative impact on these revenues. We have
sought to reduce this risk in part by entering into power sales contracts with
utilities or other customers of strong credit quality and by locating our plants
in different geographic areas in order to mitigate the effects of regional
economic downturns.

    OUR REVENUES ARE BECOMING LESS PREDICTABLE. Our business primarily consists
of businesses with long-term contracts or retail concessions, and we expect the
contract-based portfolio to be an effective hedge against future energy and
electricity market price risks. However, an increasing proportion of our current
and expected future revenues are derived from businesses without significant
long-term revenue contracts. Our increasing reliance on non-contract businesses
could cause our results of operations to become more volatile.

    OUR DISTRIBUTION BUSINESSES ARE SUBJECT TO GREATER REGULATORY SCRUTINY THAN
OUR GENERATION BUSINESS.  Our distribution businesses face increased regulatory
and political scrutiny in the normal conduct of their operations. This scrutiny
may adversely impact our results of operations, to the extent that such scrutiny
or pressure prevents us from reducing losses as quickly as we planned or denies
us a rate increase called for by our concession agreements. In general, these
businesses have lower margins and are more dependent on regulation to ensure
expected annual rate increases for inflation and increased power costs, among
other things. There can be

                                       6

no assurance that these rate reviews will be granted, or occur in a timely
manner.

    WE ARE SUBJECT TO SIGNIFICANT GOVERNMENT REGULATION.  Our generation
business in the United States is subject to the provisions of various laws and
regulations, including the Public Utility Regulatory Policies Act of 1978, as
amended, commonly referred to as PURPA, and the Public Utility Holding Company
Act, as amended, commonly referred to as PUHCA. PURPA provides to qualifying
facilities, commonly referred to as QFs, certain exemptions from substantial
federal and state legislation, including regulation as public utilities. PUHCA
regulates public utility holding companies and their subsidiaries. It is
necessary for us to obtain approval under PUHCA in order to maintain majority
ownership in our domestic power plants that are QFs. Currently a material
portion of our domestic revenues are received from QFs. Moreover, all of our
domestic non-QF plants are Exempt Wholesale Generators, commonly referred to as
EWGs. An EWG is a facility that has been authorized by the U.S. Federal Energy
Regulatory Commission, commonly referred to as the FERC, to sell wholesale power
at market-based rates. We enjoy exemptions under PUHCA related to our foreign
utility acquisitions and holdings. We cannot ensure that we will be able to
maintain appropriate PUHCA exemptions for all of our businesses. If we decide to
acquire another U.S. utility or utility assets, we may be required to divest
either all or part of CILCORP or take other steps resulting in a loss of control
or as may be required by the Securities and Exchange Commission. We believe
that, upon the occurrence of an event that would threaten the QF status of one
of our domestic plants, we would be able to react in a manner that would avoid
the loss of QF status (such as by replacing the steam customer). In the event we
were unable to avoid the loss of such status for one of our plants, to avoid
public utility holding company status, we could apply to the FERC to obtain
status as an EWG, or could restructure the ownership of the project subsidiary.
EWGs, however, are subject to broader regulation by FERC and may be subject to
state public utility commissions regulation regarding non-rate matters. In
addition, any restructuring of a project subsidiary could result in, among other
things, a reduced financial interest in such subsidiary, which could result in a
gain or loss on the sale of the interest in such subsidiary, the removal of such
subsidiary from our consolidated income tax group or our consolidated financial
statements, or an increase or decrease in our results of operations.

    PENDING ELECTRIC UTILITY INDUSTRY RESTRUCTURING PROPOSALS COULD HAVE AN
ADVERSE EFFECT ON US. Several states have passed legislation that allows
electricity customers to choose their electricity supplier in a competitive
electricity market (so-called "retail access" or "customer choice" laws), and
all but two of the remaining states are considering such legislation. In
addition to state restructuring legislation, some members of Congress have
proposed new Federal legislation to encourage customer choice and recovery of
stranded assets. Several bills have been submitted to Congress on electricity
restructuring. In anticipation of restructuring legislation, many U.S. utilities
are seeking ways to lower their costs in order to become more competitive. These
include the costs that utilities are required to pay under QF contracts. Many
utilities are therefore seeking ways to lower these contract prices by
renegotiating the contracts, or in some cases by litigation. In 1999, we
renegotiated contracts for two of our QFs--Thames (a partial prepayment) and
Placerita (a complete buyout). The Thames transaction has been approved by the
Connecticut Department of Public Utilities Commission.

    The FERC and many state utility commissions are currently studying a number
of proposals to restructure the electric utility industry in the United States.
Such restructuring would permit utility customers to choose their utility
supplier in a competitive electric energy market. The FERC issued a final rule
in April 1996 which requires utilities to offer wholesale customers and
suppliers open access on utility transmission lines, on a comparable basis to
the utilities' own use of the lines. The final rule is subject to rehearing and
may become the subject of court litigation. Many utilities have already filed
"open access" tariffs.

                                       7

The utilities contend that they should recover from departing customers their
fixed costs that will be "stranded" by the ability of their wholesale customers
(and perhaps eventually, their retail customers) to choose new electric power
suppliers. The FERC final rule endorses the recovery of legitimate and
verifiable "stranded costs." These may include the costs utilities are required
to pay under many QF contracts which the utilities view as excessive when
compared with current market prices. Many utilities are therefore seeking ways
to lower these contract prices or rescind the contracts altogether, out of
concern that their shareholders will be required to bear all or part of such
"stranded" costs. Some utilities have engaged in litigation against QFs to
achieve these ends.

    In addition, future United States electric rates may be deregulated in a
restructured United States electric utility industry and increased competition
may result in lower rates and less profit margin for United States electricity
sellers. Falling electricity prices, the introduction of commodity markets for
electricity and uncertainty as to the future structure of the industry has
rendered the long-term power purchase contracts obsolete. As a result, in the
generation business we are increasingly dependent upon prices for electricity
determined in electricity spot markets. Such prices can be very volatile and the
effect on us of this volatility cannot be predicted.

    The United States Congress is considering proposed legislation which would
repeal PURPA entirely, or at least repeal the obligation of utilities to
purchase from QFs. There is strong support for grandfathering existing QF
contracts if such legislation is passed, and also support for requiring
utilities to conduct competitive bidding for new electric generation if the
PURPA purchase obligation is eliminated. Various bills have also proposed repeal
of PUHCA. Repeal of PUHCA would allow power generators and vertically integrated
utilities to acquire retail utilities in the United States that are
geographically widespread, as opposed to the current limitations of PUHCA which
require that retail electric systems be capable of physical interconnection. In
addition, registered holding companies would be free to acquire non-utility
businesses, which they may not do now, with certain limited exceptions. In the
event that PUHCA is repealed, competition would likely increase. Repeal of PURPA
and/or PUHCA may or may not be part of comprehensive legislation to restructure
the electric utility industry, allow retail competition, and deregulate most
electric rates. The effect of any such repeal cannot be predicted, although any
such repeal could have a material adverse effect on us.

    FROM TIME TO TIME WE ARE SUBJECT TO MATERIAL LITIGATION AND REGULATORY
PROCEEDINGS.  From time to time, we and our affiliates are parties to litigation
and regulatory proceedings. Investors should review the descriptions of such
matters contained in our Annual, Quarterly and Current Reports filed with the
Securities and Exchange Commission and incorporated by reference herein. There
can be no assurances that the outcome of such matters will not have a material
adverse effect on our consolidated financial position.

    OUR BUSINESS IS SUBJECT TO STRINGENT ENVIRONMENTAL REGULATIONS.  Our
activities are subject to stringent environmental regulation by federal, state,
local and foreign governmental authorities. These regulations generally involve
effluents into the water, emissions into the air, the use of water, wetlands
preservation, waste disposal, endangered species, and noise regulation, among
others. Congress and other foreign governmental authorities also may consider
proposals to restrict or tax certain emissions. These proposals, if adopted,
could impose additional costs on the operation of our power plants. There can be
no assurance that we would be able to recover all or any increased costs from
our customers or that our business, financial condition or results of operations
would not be materially and adversely affected by future changes in domestic or
foreign environmental laws and regulations. We have made and will continue to
make capital and other expenditures to comply with environmental laws and
regulations. There can be no assurance that such expenditures will not have a
material adverse effect on our financial condition or results of operations.

                                       8

    OUR DIRECTORS AND OFFICERS HAVE SIGNIFICANT OWNERSHIP INTERESTS IN US AND
CAN EXERT SIGNIFICANT INFLUENCE OR CONTROL OVER MATTERS REQUIRING STOCKHOLDER
APPROVAL.  As of February 4, 2000 our two founders, Roger W. Sant and Dennis W.
Bakke, and their immediate families together owned beneficially approximately
18.4% of our outstanding Common Stock. As a result of their ownership interests,
Messrs. Sant and Bakke may be able to significantly influence or exert control
over our affairs, including the election of our directors. As of February 4,
2000, all of our officers and directors and their immediate families together
owned beneficially approximately 24.9% of our outstanding Common Stock. To the
extent that they decide to vote together, these stockholders would be able to
significantly influence or control the election of our directors, our management
and policies and any action requiring stockholder approval, including
significant corporate transactions.

    OUR ADHERENCE TO OUR "SHARED PRINCIPLES" COULD HAVE AN ADVERSE IMPACT ON OUR
RESULTS OF OPERATIONS.  A core part of our corporate culture is a commitment to
"shared principles": to act with integrity, to be fair, to have fun and to be
socially responsible. We seek to adhere to these principles not as a means to
achieve economic success, but because adherence is a worthwhile goal in and of
itself. However, if we perceive a conflict between these principles and profits,
we will try to adhere to our principles--even though doing so might result in
diminished or foregone opportunities or financial benefits.

    SHARES ELIGIBLE FOR FUTURE SALE.  From time to time, our subsidiaries incur
indebtedness that is secured by a pledge of shares of our common stock held by
that subsidiary. The sale of a substantial number of such shares in the public
market upon any foreclosure or otherwise could have an adverse effect on the
market price of our common stock.

    RISK OF FRAUDULENT TRANSFER.  Various fraudulent conveyance laws have been
enacted for the protection of creditors and may be applied by a court on behalf
of any unpaid creditor or a representative of our creditors in a lawsuit to
subordinate or avoid Debt Securities in favor of our other existing or future
creditors. Under applicable provisions of the U.S. Bankruptcy code or comparable
provisions of state fraudulent transfer or conveyance laws, if we at the time of
issuance of Debt Securities,

    - incurred such indebtedness with intent to hinder, delay or defraud any of
      our present or future creditors or contemplated insolvency with a design
      to prefer one or more creditors to the exclusion in whole or in part of
      others or

    - received less than reasonably equivalent value or fair consideration for
      issuing Debt Securities and we:

      - were insolvent,

      - were rendered insolvent by reason of the issuance of the Debt
        Securities,

      - were engaged or about to engage in business or a transaction for which
        our remaining assets constitute unreasonably small capital to carry on
        our business, or

      - intended to incur, or believed that we would incur, debts beyond our
        ability to pay such debts as they mature,

    then, in each case, a court of competent jurisdiction could void, in whole
or in part, the Debt Securities.

    Among other things, a legal challenge of the Debt Securities on fraudulent
conveyance grounds may focus on the benefits, if any, realized by us as a result
of our issuance of the Debt Securities.

    The measure of insolvency for purposes of the foregoing will vary depending
upon the law applied in such case. Generally, however, we would be considered
insolvent if the sum of our debts, including contingent liabilities, were
greater than all of our assets at fair valuation or if the present fair market
value of our assets were less than the amount that would be required to pay the
probable liability on our existing debts, including contingent liabilities, as
they become absolute and mature. There can be no assurance that, after providing
for all prior

                                       9

claims, there will be sufficient assets to satisfy the claims of the holders of
the Debt Securities.

    Management believes that, for purposes of all such insolvency, bankruptcy
and fraudulent transfer or conveyance laws, the Debt Securities are being
incurred without the intent to hinder, delay or defraud creditors and for proper
purposes and in good faith, and that we, after the issuance of the Debt
Securities, will be solvent, will have sufficient capital for carrying on our
business and will be able to pay our debts as they mature. There can be no
assurance, however, that a court passing on such questions would agree with
management's view.

    THERE IS NO PRIOR PUBLIC MARKET FOR MANY OF THE SECURITIES THAT MAY BE
OFFERED PURSUANT TO THIS PROSPECTUS--AS A RESULT THERE COULD BE SIGNIFICANT
PRICE VOLATILITY FOR SUCH SECURITIES.  Prior to the offering, there has been no
public market for many of the securities that may be offered pursuant to this
prospectus. There can be no assurance that an active trading market for any of
such securities will develop or be sustained. If such a market were to develop,
such securities could trade at prices that may be higher or lower than their
initial offering price depending upon many factors, including prevailing
interest rates, our operating results and the markets for similar securities.

                       RATIO OF EARNINGS TO FIXED CHARGES

    Our ratio of earnings to fixed charges is as follows:



                                                                                                                 THREE MONTHS
                                                                                                                    ENDED
                                                                        YEAR ENDED DECEMBER 31,                   MARCH 31,
                                                          ----------------------------------------------------   ------------
                                                            1995       1996       1997       1998       1999         2000

Ratio of earnings to fixed charges......................    2.20       1.88       1.46       1.65       1.50         2.08


    For the purpose of computing the ratio of earnings to fixed charges,
earnings consist of income from continuing operations before income taxes and
minority interest, plus depreciation of previously capitalized interest, plus
fixed charges, less capitalized interest, less excess of earnings over dividends
of less-than-fifty-percent-owned companies, less minority interest in pre-tax
income of subsidiaries that have not incurred fixed charges, less preference
security dividend requirements of a consolidated subsidiary. Fixed charges
consist of interest (including capitalized interest) on all indebtedness,
amortization of debt discount and capitalized expenses, preference security
dividend requirements of a consolidated subsidiary, and that portion of rental
expense which we believe to be representative of an interest factor.

    During the period from January 1, 1995 until March 31, 2000, no shares of
preferred stock were issued or outstanding, and during that period we did not
pay any preferred stock dividends.

                                  THE COMPANY

    We are a global power company committed to serving the world's needs for
electricity in a socially responsible way. Our electricity "generation" business
consists of sales to wholesale customers (generally electric utilities, regional
electric companies or wholesale commodity markets known as "power pools") for
further resale to end-users. We also sell electricity directly to end-users such
as commercial, industrial, governmental and residential customers through our
"distribution" business.

    Sales within our generation business are made under long-term contracts from
power plants owned by our subsidiaries and affiliates, as well as directly into
power pools. We own new plants constructed for such purposes ("greenfield"
plants) as well as older power plants acquired through competitively bid
privatization initiatives or negotiated acquisitions.

    Electricity sales by our distribution businesses, including affiliates, are
generally made pursuant of the provisions of long-term electricity sale
concessions granted by the appropriate governmental authorities. In certain
cases, these distribution companies are "integrated", in that they also own
electric power plants for the purpose of generating a portion of the electricity
they sell.

                          DESCRIPTION OF CAPITAL STOCK

    Under our certificate of incorporation (the "Certificate of Incorporation"),
we are authorized to issue 1,200,000,000 shares of common stock, par value $.01
per share, and 50,000,000 shares of preferred stock, no par value.

                                       12

    The following summary contains a description of certain general terms of the
common stock and the preferred stock to which any prospectus supplement may
relate. Certain terms of any series of preferred stock offered by a prospectus
supplement will be described in the prospectus supplement relating thereto. If
indicated in the prospectus supplement, the terms of any series may differ from
the terms set forth below. The description of certain provisions of the common
stock and the preferred stock is subject to and qualified by reference to the
provisions of our certificate of incorporation, and, in the case of the
preferred stock, to the certificate of designation (the "Certificate of
Designation") relating to each particular series of preferred stock which will
be filed or incorporated by reference as an exhibit to the registration
statement of which this prospectus is a part.

COMMON STOCK

    As of May 1, 2000, there were 207,770,572 shares of common stock
outstanding.

    The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable to any outstanding preferred stock, the holders of common stock are
entitled to receive ratably dividends as may be declared from time to time by
our board of directors out of funds legally available to pay dividends. If we
liquidate our business, the holders of common stock are entitled to share
ratably in all assets after we pay our liabilities and the liquidation
preference of any outstanding preferred stock. The common stock has no
preemptive or conversion rights or other subscription rights. There are no
redemption or sinking fund provisions applicable to the common stock. All
outstanding shares of common stock are fully paid and non-assessable, and any
shares of common stock in respect of which this prospectus is being delivered
will be fully paid and non-assessable.

    The transfer agent for our common stock is EquiServe.

PRICE RANGE OF AES COMMON STOCK AND COMMON STOCK DIVIDENDS

    Our common stock began trading on the New York Stock Exchange on
October 16, 1996 under the symbol "AES." The following table sets forth for the
periods indicated the intra-day high and low sale prices for the common stock as
reported on the Composite Tape. In April 2000, we announced a two-for-one stock
split, in the form of a stock dividend, for holders of record on May 1, 2000 of
our common stock, par value $.01 per share, which is payable on June 1, 2000.
The prices set forth below do not reflect adjustment for such stock split.

    No cash dividends have been paid on common stock since December 22, 1993 in
order to provide capital for our equity investments in projects.

    Our ability to declare and pay dividends is dependent, among other things,
on

    - the ability of our project subsidiaries to declare and pay dividends and
      otherwise distribute cash to us;

    - our ability to service our parent company debt and

    - our ability to meet certain criteria for paying dividends under our
      corporate

                                       13

      credit facility and under existing indentures of our debt securities.

    The ability of our subsidiaries to declare and pay dividends and otherwise
distribute cash to us is subject to certain limitations in the project loans and
other documents entered into by our project subsidiaries. These limitations
permit the payment of dividends out of current cash flow for quarterly,
semi-annual or annual periods only at the end of these periods and only after
payment of principal and interest on project loans due at the end of these
periods.

    Cash dividend payments on common stock are limited to a certain percentage
of cash flow under our corporate credit agreement. The indentures relating to
our existing senior subordinated notes preclude the payment of cash dividends
if:

    - at the time of a payment of cash dividends or after giving effect thereto
      an event of default occurred;

    - an event that would become an event of default occurred and is continuing;

    - certain fixed charge coverage ratios are not met or

    - if the payment of dividends, together with other restricted payments,
      would exceed certain limits.

PREFERRED STOCK

    As of May 1, 2000, there were no shares of Preferred Stock outstanding.

    Our board of directors has the authority to issue preferred stock in one or
more classes or series and to fix the rights, preferences, privileges and
restrictions thereof, including dividend rights, dividend rates, conversion
rights, exchange rights, voting rights, terms of redemption, redemption prices,
liquidation preferences and the number of shares constituting any class or
series or the designation of such class or series, without any further action by
the stockholders. Preferred stock, if issued, will not be entitled to any
preemptive or similar rights. The prospectus supplement will describe the terms
of any preferred stock being offered, including:

    - the specific designation, number of shares, seniority and purchase price;

    - any liquidation preference per share;

    - any date of maturity;

    - any redemption, repayment or sinking fund provisions;

    - any dividend rate or rates and the dates on which any such dividends will
      be payable (or the method by which such rates or dates will be
      determined);

    - any voting rights;

    - if other than the currency of the United States, the currency or
      currencies including composite currencies in which such preferred stock is
      denominated and/or in which payments will or may be payable;

    - the method by which amounts in respect of such preferred stock may be
      calculated and any commodities, currencies or indices, or value, rate or
      price, relevant to such calculation;

    - whether such preferred stock is convertible or exchangeable and, if so,
      the securities or rights into which such preferred stock is convertible or
      exchangeable, and the terms and conditions upon which such conversions or
      exchanges will be effected including conversion or exchange prices or
      rates, the conversion or exchange period and any other related provisions;

    - the place or places where dividends and other payments on the preferred
      stock will be payable; and

    - any additional voting, dividend, liquidation, redemption and other rights,
      preferences, privileges, limitations and restrictions.

    All shares of preferred stock offered hereby, or issuable upon conversion,
exchange or

                                       14

exercise of securities, will, when issued, be fully paid and non-assessable. Any
shares of preferred stock that are issued would have priority over the common
stock with respect to dividend or liquidation rights or both.

    The transfer agent for each series of preferred stock will be described in
the applicable prospectus supplement.

DESCRIPTION OF CERTAIN PROVISIONS OF OUR CERTIFICATE OF INCORPORATION AND
BY-LAWS

    Our Certificate of Incorporation and By-Laws contain several provisions that
may make the acquisition of control of the AES through a tender offer, open
market purchases, a proxy fight or otherwise more difficult. Below is a
description of certain of these provisions in the Certificate of Incorporation
and By-Laws.

    SPECIAL MEETINGS OF STOCKHOLDERS.  Our By-Laws provide that, unless
otherwise prescribed by law, special meetings of stockholders may be called by a
resolution adopted by a majority of the entire board of directors, by the
chairman of the board of directors or by the president. Only business as
specified in the notice of stockholders of the special meeting shall be
considered.

    STOCKHOLDER NOMINATION OF DIRECTORS.  Our By-Laws contain a procedure for
stockholder nomination of directors. The By-Laws provide that any record owner
of stock entitled to be voted generally in the election of directors may
nominate one or more persons for election as a director at a stockholders
meeting only if written notice is given to our secretary of the intent to make a
nomination. The notice must be given, with respect to an annual meeting, not
later than 90 days in advance of the annual meeting. With respect to a special
meeting, the notice must be given not later than the close of business on the
seventh day following the earlier of

    - the date on which notice of such special meeting is first given to
      stockholders and

    - the date on which a public announcement of such meeting is first made.

    Each notice must include:

    - the name and address of each stockholder who intends to appear in person
      or by proxy to make the nomination and of the person or persons to be
      nominated;

    - a description of all arrangements or understandings between the
      stockholder and each nominee and any other person or persons (naming them)
      pursuant to which the nomination is to be made by the stockholder;

    - other information regarding each nominee proposed as would have been
      included in a proxy statement filed pursuant to Rule 14a-8 under the
      Exchange Act and

    - the consent of each nominee to serve if elected.

    The presiding officer of the meeting may refuse to acknowledge the
nomination of any person not made in compliance with this procedure.

    The procedure for stockholder nomination of directors described above may
have the effect of precluding a nomination for election of directors at a
particular meeting if the required procedure is not followed.

    ELIMINATION OF LIABILITY; INDEMNIFICATION. Except as described below, the
Certificate of Incorporation eliminates the liability of members of our board of
directors to us or our stockholders for monetary damages resulting from breaches
of their fiduciary duties as directors. Directors remain liable for breaches of
their duty of loyalty to us or our stockholders, as well as for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law and transactions from which a director derives improper
personal benefit. The Certificate of Incorporation also does not release
directors of liability under Section 174 of the Delaware General Corporation Law
(the "GCL"), which makes directors personally liable for unlawful dividends or
unlawful stock repurchases or redemptions if

                                       15

the unlawful conduct is willful or results from negligence.

    Under our By-Laws, and in accordance with Section 145 of the GCL, we shall
indemnify to the fullest extent permitted by the GCL any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding. These include civil, criminal,
administrative or investigative proceedings by reason of the fact that the
person is or was a director or officer of or employed by us, or is or was
serving in that capacity or as an agent at the request of us for another entity.
Our indemnification covers expenses, judgments, fines and amounts paid in
settlement actually and reasonably incurred in connection with the defense or
settlement of an action, suit or proceeding if the person acted in good faith
and in a manner the person reasonably believed to be in or not opposed to our
best interests and, with respect to any criminal action or proceeding, had no
reasonable cause to believe was unlawful. We will indemnify persons in a
derivative action under the same conditions, except that no indemnification is
permitted without judicial approval if the person is adjudged to be liable to us
in the performance of his or her duty. Derivative actions are actions by us or
in the right of us to procure a judgment in our favor. Agents of ours may be
similarly indemnified at the discretion of the board of directors.

    Under Section 145 of the GCL, a similar duty of care is applicable in the
case of derivative actions, except that indemnification only extends to expenses
incurred in connection with the defense or settlement of a derivative action and
then, where the person is adjudged to be liable to us, only if and to the extent
that the Court of Chancery of the State of Delaware or the court in which the
action was brought determines that the person is fairly and reasonably entitled
to the indemnity and only for those expenses as the court deems proper.

    Pursuant to our By-Laws, a person eligible for indemnification may have the
expenses incurred in connection with any matter described above paid in advance
of a final disposition by us. However, these advances will only be made if the
indemnified person undertakes to repay all advanced amounts if it is determined
that the person is not entitled to indemnification.

    In addition, under our By-Laws, we may purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of us
or of another corporation against any liability arising out of the person's
status as director, officer, employee or agent of us whether or not we would
have the power to indemnify such person against such liability under the
provisions of our By-Laws. We maintain directors' and officers' insurance.

DEPOSITARY SHARES

    GENERAL.  We may, at our option, elect to offer fractional shares of
preferred stock, rather than full shares of preferred stock. If we exercise this
option, we will issue to the public receipts for depositary shares, and each of
these depositary shares will represent a fraction (to be set forth in the
application prospectus supplement) of a share of a particular series of
preferred stock.

    The shares of any series of preferred stock underlying the depositary shares
will be deposited under a deposit agreement between us and a bank or trust
company selected by us. The depositary will have its principal office in the
United States and a combined capital and surplus of at least $50,000,000.
Subject to the terms of the deposit agreement, each owner of a depositary share
will be entitled, in proportion, to the applicable fraction of a share of
preferred stock underlying that depositary share, to all the rights and
preferences of the preferred stock underlying that depositary share. Those
rights include dividend, voting, redemption and liquidation rights.

    The depositary shares will be evidenced by depositary receipts issued
pursuant to the deposit agreement. Depositary receipts will be distributed to
those persons purchasing the fractional shares of preferred stock underlying the
depositary shares, in accordance with the terms of the offering. Copies of the
forms of deposit agreement and depositary receipt will be filed as exhibits to
the registration statement.

                                       16

The following summary of the deposit agreement, the depositary shares and the
depositary receipts is not complete. You should refer to the forms of the
deposit agreement and depositary receipts that will be filed with the Securities
and Exchange Commission in connection with the offering of the specific
depositary shares.

    Pending the preparation of definitive engraved depositary receipts, the
depositary may, upon our written order, issue temporary depositary receipts
substantially identical to the definitive depositary receipts but not in
definitive form. These temporary depositary receipts entitle their holders to
all the rights of definitive depositary receipts which are to be prepared
without unreasonable delay. Temporary depositary receipts will then be
exchangeable for definitive depositary receipts at our expense.

    DIVIDENDS AND OTHER DISTRIBUTIONS.  The depositary will distribute all cash
dividends or other cash distributions received with respect to the preferred
stock to the record holders of depositary shares relating to the preferred stock
in proportion to the number of depositary shares owned by those holders.

    If there is a distribution other than in cash, the depositary will
distribute property received by it to the record holders of depositary shares
that are entitled to receive the distribution, unless the depositary determines
that it is not feasible to make the distribution. If this occurs, the depositary
may, with our approval, sell the property and distribute the net proceeds from
the sale to the applicable holders.

    REDEMPTION OF DEPOSITARY SHARES.  If a series of preferred stock represented
by depositary shares is subject to redemption, the depositary shares will be
redeemed from the proceeds received by the depositary resulting from the
redemption, in whole or in part, of that series of preferred stock held by the
depositary. The redemption price per depositary share will be equal to the
applicable redemption fraction of the redemption price per share payable with
respect to that series of the preferred stock. Whenever we redeem shares of
preferred stock that are held by the depositary, the depositary will redeem, as
of the same redemption date, the number of depositary shares representing the
shares of preferred stock so redeemed. If fewer than all the depositary shares
are to be redeemed, the depositary shares to be redeemed will be selected by lot
or pro rata as may be determined by the depositary.

    VOTING THE PREFERRED STOCK.  Upon receipt of notice of any meeting at which
the holders of the preferred stock are entitled to vote, the depositary will
mail the information contained in such notice to the record holders of the
depositary shares underlying the preferred stock. Each record holder of the
depositary shares on the record date (which will be the same date as the record
date for the preferred stock) will be entitled to instruct the depositary as to
the exercise of the voting rights pertaining to the amount of the preferred
stock represented by such holder's depositary shares. The depositary will then
try, as far as practicable, to vote the number of shares of preferred stock
underlying those depositary shares in accordance with such instructions, and we
will agree to take all actions which may be deemed necessary by the depositary
to enable the depositary to do so. The depositary will not vote the shares of
preferred stock to the extent it does not receive specific instructions from the
holders of depositary shares underlying the preferred stock.

    AMENDMENT AND TERMINATION OF THE DEPOSITARY AGREEMENT.  The form of
depositary receipt evidencing the depositary shares and any provision of the
deposit agreement may at any time be amended by agreement between us and the
depositary. However, any amendment which materially and adversely alters the
rights of the holders of depositary shares will not be effective unless the
amendment has been approved by the holders of at least a majority of the
depositary shares then outstanding. The deposit agreement may be terminated by
us or by the depositary only if (a) all outstanding depositary shares have been
redeemed or (b) there has been a final distribution of the underlying preferred
stock in connection with our liquidation, dissolution or winding up and the
preferred stock has been distributed to the holders of depositary receipts.

                                       17

    CHARGES OF DEPOSITARY.  We will pay all transfer and other taxes and
governmental charges arising solely from the existence of the depositary
arrangements. We will also pay charges of the depositary in connection with the
initial deposit of the preferred stock and any redemption of the preferred
stock. Holders of depositary receipts will pay other transfer and other taxes
and governmental charges and those other charges, including a fee for the
withdrawal of shares of preferred stock upon surrender of depositary receipts,
as are expressly provided in the deposit agreement to be for their accounts.

    MISCELLANEOUS.  The depositary will forward to holders of depositary
receipts all reports and communications from us that we deliver to the
depositary and that we are required to furnish to the holders of the preferred
stock.

    Neither we nor the depositary will be liable if either of us is prevented or
delayed by law or any circumstance beyond our control in performing our
respective obligations under the deposit agreement. Our obligations and those of
the depositary will be limited to performance in good faith of our respective
duties under the deposit agreement. Neither we nor the depositary will be
obligated to prosecute or defend any legal proceeding in respect of any
depositary shares or preferred stock unless satisfactory indemnity is furnished.
We and the depositary may rely upon written advice of counsel or accountants, or
upon information provided by persons presenting preferred stock for deposit,
holders of depositary receipts or other persons believed to be competent and on
documents believed to be genuine.

    RESIGNATION AND REMOVAL OF DEPOSITARY.  The depositary may resign at any
time by delivering notice to us of its election to resign. We may remove the
depositary at any time. Any resignation or removal will take effect upon the
appointment of a successor depositary and its acceptance of the appointment. The
successor depositary must be appointed within 60 days after delivery of the
notice of resignation or removal and must be a bank or trust company having its
principal office in the United States and having a combined capital and surplus
of at least $50,000,000.

                         DESCRIPTION OF DEBT SECURITIES

    The debt securities may consist of Senior Debt Securities, Subordinated Debt
Securities or Junior Subordinated Debt Securities. The Senior Debt Securities
will be issued under an indenture (the "Senior Debt Indenture") between AES, as
issuer, and either Bank One, National Association (formerly known as The First
National Bank of Chicago) or The Bank of New York, as trustee. The Senior
Subordinated Debt Securities will be issued under an indenture (the "Senior
Subordinated Debt Indenture") between AES, as issuer, and either Bank One,
National Association (formerly known as The First National Bank of Chicago) or
The Bank of New York, as trustee. The Junior Subordinated Debt Securities will
be issued under an indenture (the "Junior Subordinated Debt Indenture") between
AES, as issuer, and either Bank One, National Association (formerly known as The
First National Bank of Chicago) or The Bank of New York, as trustee. The Senior
Debt Indenture, the Senior Subordinated Debt Indenture and the Junior
Subordinated Debt Indenture are collectively referred to herein as the
"Indentures."

    The Indentures have been incorporated by reference or included herein as
exhibits to the registration statement of which this Prospectus is a part and
are also available for inspection at the office of the trustee. The Indentures
are subject to and governed by the Trust Indenture Act of 1939 (the "Trust
Indenture Act"). Section references contained herein are applicable to each of
the Indentures. The following summaries of the Indentures are not complete.
Where reference is made to particular provisions of the Indentures, these
provisions, including definitions of certain terms, are incorporated by
reference. The Indentures are substantially identical except for provisions
relating to subordination.

                                       18

GENERAL

    None of the Indentures limits the amount of debt securities which may be
issued thereunder. Each Indenture provides that debt securities issuable
thereunder may be issued up to the aggregate principal amount which may be
authorized by us from time to time. The prospectus supplement will describe the
terms of any debt securities being offered (the "Offered Debt Securities")
including:

    - the designation, aggregate principal amount and authorized denominations
      of the Offered Debt Securities;

    - the date or dates on which the Offered Debt Securities mature;

    - the rate or rates per annum at which the Offered Debt Securities will bear
      interest and the method of calculating interest rates, if any;

    - the dates on which any interest will be payable and the record dates for
      any interest payments;

    - any mandatory or optional redemption terms or prepayment, conversion,
      sinking fund or exchangeability provisions;

    - the place where the principal of and interest on the Offered Debt
      Securities will be payable;

    - if other than denominations of $1,000 or multiples thereof, the
      denominations in which the Offered Debt Securities will be issuable;

    - whether the Offered Debt Securities will be issued in the form of Global
      Securities (as defined below) or certificates;

    - additional provisions, if any, relating to the defeasance of the Offered
      Debt Securities;

    - the currency or currencies, if other than the currency of the United
      States, in which payment of the principal of and interest on the Offered
      Debt Securities will be payable;

    - whether the Offered Debt Securities will be issuable in registered form or
      bearer form ("Bearer Securities") or both and, if Bearer Securities are
      issuable, any restrictions applicable to the exchange of one form for
      another and the offer, sale and delivery of Bearer Securities;

    - any applicable United States federal income tax consequences, including
      whether and under what circumstances we will pay additional amounts on
      Offered Debt Securities held by a person who is not a U.S. Person (as
      defined in each prospectus supplement relating to any particular series of
      debt securities offered thereby) in respect of any tax, assessment or
      governmental charge withheld or deducted and, if so, whether we will have
      the option to redeem these Offered Debt Securities rather than pay the
      additional amounts;

    - the dates on which premium, if any, will be payable;

    - our right, if any, to defer payment of interest and the maximum length of
      any deferral period;

    - any listing on a securities exchange;

    - other specific terms, including any additional events of default or
      covenants provided for with respect to the Offered Debt Securities.

    As described in each prospectus supplement relating to any particular series
of debt securities offered thereby, the indenture may contain covenants
limiting:

    - the incurrence of debt by us;

    - the incurrence of debt by subsidiaries of us;

    - the making of certain payments by us and our subsidiaries;

    - subsidiary mergers;

    - business activities of us and our subsidiaries;

    - the issuance of preferred stock of subsidiaries;

                                       19

    - asset dispositions;

    - transactions with affiliates;

    - liens and

    - mergers and consolidations involving AES.

BOOK-ENTRY SYSTEMS

    If so specified in any prospectus supplement relating to debt securities,
debt securities of any series may be issued under a book-entry system in the
form of one or more global securities (each, a "Global Security"). Each Global
Security will be deposited with, or on behalf of, a depositary, which will be
The Depository Trust Company, New York, New York (the "Depositary"). The Global
Securities will be registered in the name of the Depositary or its nominee.

    The Depositary has advised us that the Depositary is a limited purpose trust
company organized under the laws of the State of New York, 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 Exchange Act. The Depositary was created to
hold securities of its participants and to facilitate the clearance and
settlement of securities transactions among its participants through electronic
book-entry changes in accounts of the participants, thereby eliminating the need
for physical movement of securities certificates. The Depositary's participants
include securities brokers and dealers, banks, trust companies, clearing
corporations, and certain other organizations, some of which (and/or their
representatives) own the Depositary. Access to the Depositary's book-entry
system is also available to others, such as banks, brokers, dealers, and trust
companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly.

    When a Global Security is issued in registered form, the Depositary will
credit, on its book-entry registration and transfer system, the respective
principal amounts of the debt securities represented by each Global Security to
the participants' accounts. The accounts to be credited will be designated by
the underwriters, dealers, or agents, if any. If debt securities are offered and
sold directly by us, we will designate the accounts to be credited. Ownership of
beneficial interests in the Global Security will be limited to participants or
persons that may hold interests through participants. Ownership of beneficial
interests by participants in the Global Security will be shown on, and the
transfer of that ownership interest will be effected only through, the
participants' records. The laws of some jurisdictions may require that certain
purchasers of securities take physical delivery of the securities in definitive
form. These laws may impair the ability to transfer beneficial interests in a
Global Security.

    So long as the Depositary or its nominee is the owner of record of a Global
Security, we consider the Depositary or its nominee the sole owner or holder of
the debt securities represented by the Global Security for all purposes under
the Indenture under which the debt securities are issued. Except as set forth
below, owners of beneficial interests in a Global Security will not be entitled
to have the debt security represented by the Global Security registered in their
names, and will not receive or be entitled to receive physical delivery of the
Debt Securities in definitive form and will not be considered the owners or
holders thereof under the Indenture under which these debt securities are
issued. Accordingly, each person owning a beneficial interest in a Global
Security must rely on the procedures of the Depositary. Persons who are not
participants must rely on the procedures of the participant through which they
own their interest. We understand that under existing industry practices, if we
request any action of holders or if any owner of a beneficial interest in a
Global Security desires to give or take any action which a holder is entitled to
give or take under the applicable Indenture, the Depositary would authorize the
participants holding the relevant beneficial interests to give or take such
action, and such participants would authorize beneficial owners owning through
such participants to give or take such action or would

                                       20

otherwise act upon the instruction of beneficial owners holding through them.

    Payments of principal, premium, if any, and interest on debt securities
represented by a Global Security registered in the name of the Depositary or its
nominee will be made to the Depositary or nominee, as the registered owner. None
of AES, the trustee or any other agent of us or agent of the 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 the Global
Security or for maintaining, supervising, or reviewing any records relating to
such beneficial ownership interests.

    We have been advised by the Depositary that the Depositary will credit
participants' accounts with payments of principal, premium, if any, or interest
on the payment date thereof in amounts proportionate to their respective
beneficial interests in the principal amount of the Global Security as shown on
the records of the Depositary. We expect that payments by participants to owners
of beneficial interests in the Global Security held through such participants
will be governed by standing instructions and customary practices, as is now the
case with securities held for the accounts of customers registered in "street
name," and will be the responsibility of such participants.

    A Global Security may not be transferred except as a whole:

    - by the Depositary to a nominee or successor of the Depositary or

    - by a nominee of the Depositary to another nominee of the Depositary.

    A Global Security representing all but not part of an offering of debt
securities hereby is exchangeable for debt securities in definitive form of like
tenor and terms if:

    - The Depositary notifies us that it is unwilling or unable to continue as
      depositary for the Global Security or if at any time the Depositary is no
      longer eligible to be in good standing as a clearing agency registered
      under the Exchange Act, and we do not appoint a successor depositary
      within 90 days after we receive notice or become aware of the
      ineligibility or

    - We in our sole discretion at any time determine not to have all of the
      debt securities represented in an offering of Offered Debt Securities by a
      Global Security and notify the trustee thereof.

    A Global Security exchangeable pursuant to the preceding sentence shall be
exchangeable for debt securities registered in the names and in the authorized
denominations as the Depositary for the Global Security shall direct. The debt
securities of a series may also be issued in the form of one or more bearer
global debt securities (a "Bearer Global Security") that will be deposited with
a common depositary for Euroclear and Clearstream, or with a nominee for that
depositary identified in the prospectus supplement relating to the series. The
specific terms and procedures, including the specific terms of the depositary
arrangement, with respect to any portion of a series of debt securities to be
represented by a Bearer Global Security will be described in the prospectus
supplement.

SENIOR DEBT SECURITIES

    The payment of principal, premium, if any, and interest on the Senior Debt
Securities will, to the extent and in the manner set forth in the Senior Debt
Indenture, rank equally with all unsecured and unsubordinated debt.

SUBORDINATION OF SENIOR SUBORDINATED DEBT SECURITIES

    The payment of principal, premium, if any, and interest on the Senior
Subordinated Debt Securities will, to the extent and in the manner set forth in
the Senior Subordinated Debt Indenture, be subordinated in right of payment to
the prior payment in full, in cash equivalents, of all Senior Debt.

    Upon any payment or distribution of assets to our creditors upon any
liquidation, dissolution, winding up, receivership, reorganization, assignment
for the benefit of creditors, marshaling of assets and liabilities or

                                       21

any bankruptcy, insolvency or similar proceedings, 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 Senior Subordinated Debt Securities
will be entitled to receive any payment in respect of the principal, premium, if
any, or interest on the Senior Subordinated Debt Securities.

    No payments of principal, premium, if any, or interest in respect of the
Senior Subordinated Debt Securities may be made by us if a default in any
payment with respect to Senior Debt has occurred and is continuing. In addition,
during the continuance of any other event of default (other than a payment
default) with respect to Designated Senior Debt pursuant to which the maturity
thereof may be accelerated, no payments of principal, premium, if any, or
interest in respect of the Senior Subordinated Debt Securities may be made by us
for a period (the "Payment Blockage Period") beginning on the date of delivery
of written notice of the holders and ending 179 days thereafter (unless the
Payment Blockage Period shall be terminated by written notice to the trustee
from the holders of Designated Senior Debt or from an agent of these holders, or
the event of default has been cured or waived or has ceased to exist). Only one
Payment Blockage Period may be commenced with respect to the Senior Subordinated
Debt Securities during any period of 360 consecutive days. No event of default
which existed or was continuing on the date of the beginning of any Payment
Blockage Period shall be the basis for the beginning of any subsequent Payment
Blockage Period by the holders of Designated Senior Debt, unless such event of
default shall have been cured or waived for a period of not less than 90 days.

    Due to this subordination, in the event of insolvency, funds that would
otherwise be payable to holders will be paid to the holders of Senior Debt to
the extent necessary to pay the Senior Debt in full, and we may be unable to
meet fully our obligations with respect to the Senior Subordinated Debt
Securities.

    "Debt" is defined to mean, with respect to any person at any date of
determination (without duplication):

    - all indebtedness for borrowed money;

    - all obligations evidenced by bonds, debentures, notes or other similar
      instruments;

    - all obligations in respect of letters of credit or bankers' acceptance or
      other similar instruments (or reimbursement obligations with respect
      thereto);

    - all obligations to pay the deferred purchase price of property or
      services, except trade payables;

    - all obligations as lessee under capitalized leases;

    - all Debt of others secured by a lien on any asset of the person, whether
      or not the Debt is assumed by that person; provided that, for purposes of
      determining the amount of any Debt of the type described in this clause,
      if recourse with respect to that Debt is limited to that asset, the amount
      of that Debt shall be limited to the lesser of the fair market value of
      the asset or the amount of the Debt;

    - all Debt of others guaranteed by that person to the extent that Debt is
      guaranteed by such person;

    - all redeemable stock valued at the greater of its voluntary or involuntary
      liquidation preference plus accrued and unpaid dividends; and,

    - to the extent not otherwise included in this definition, all obligations
      under currency agreements and interest rate agreements.

    "Designated Senior Debt" is defined to mean:

    - Debt under the Credit Agreement dated as of August 2, 1996 (the "Credit

                                       22

      Agreement") among The AES Corporation, the banks named on the signature
      pages thereof and the Morgan Guaranty Trust Company of New York, as agent
      for the banks, as such Credit Agreement has been and may be amended,
      restated, supplemented or otherwise modified from time to time; and

    - Debt constituting Senior Debt which, at the time of its determination

      - has an aggregate principal amount of at least $30 million; and

      - is specifically designated by us as "Designated Senior Debt."

    "Senior Debt" is defined to mean the principal of, premium, if any, and
interest on all of our Debt whether created, incurred or assumed before, on or
after the date of the Senior Subordinated Debt Indenture; provided that Senior
Debt shall not include:

    - our 8.875% Senior Subordinated Debentures due 2027, 8.50% Senior
      Subordinated Notes due 2007, 8.375% Senior Subordinated Notes Due 2007 and
      our 10.25% Senior Subordinated Notes due 2006 which rank equally with the
      Senior Subordinated Debt Securities;

    - our Debt to any affiliate;

    - Debt of ours that, when incurred, and without respect to any election
      under Section 1111(b) of Title 11, U.S. Code, was without recourse;

    - any other Debt of ours which by the terms of the instrument creating or
      evidencing the same are specifically designated as not being senior in
      right of payment to the Senior Subordinated Debt Securities; and

    - our redeemable stock.

SUBORDINATION OF JUNIOR SUBORDINATED DEBT SECURITIES

    The payment of principal, premium, if any, and interest on the Junior
Subordinated Debt Securities will, to the extent and in the manner set forth in
the Junior Subordinated Debt Indenture, be subordinated in right of payment to
the prior payment in full, in cash or cash equivalents, of all our Senior and
Subordinated Debt.

    Upon any payment or distribution of assets to our creditors upon any
liquidation, dissolution, winding up, receivership, reorganization, assignment
for the benefit of creditors, marshaling of assets and liabilities or any
bankruptcy, insolvency or similar proceedings, the holders of all Senior and
Subordinated 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, premium, if any, or interest on the Junior Subordinated Debt
Securities.

    No payments of principal, premium, if any, or interest in respect of the
Junior Subordinated Debt Securities may be made by us if a default in any
payment with respect to Senior and Subordinated Debt has occurred and is
continuing. In addition, during the continuance of any other event of default
(other than a payment default) with respect to Designated Senior and
Subordinated Debt pursuant to which the maturity thereof may be accelerated, no
payments on account of principal, premium, if any, or interest may be made by us
during a Payment Blockage Period in respect of these Junior Subordinated Debt
Securities (unless the Payment Blockage Period is terminated by written notice
to the trustee from the holders of Designated Senior and Subordinated Debt or
from an agent of such holders, or the event of default has been cured or waived
or has ceased to exist). Only one Payment Blockage Period may be commenced with
respect to the Junior Subordinated Debt Securities during any period of 360
consecutive days. No event of default which existed or was continuing on the
date of the beginning of any Payment Blockage Period with respect to the
Designated Senior and Subordinated Debt initiating the Payment Blockage Period
shall be the basis for the beginning of any subsequent Payment Blockage Period
by the holders of such Designated Senior and Subordinated Debt, unless such
event of

                                       23

default shall have been cured or waived for a period of not less than 90
consecutive days.

    Due to this subordination, in the event of insolvency, funds that would
otherwise be payable to holders of Junior Subordinated Debt Securities will be
paid to the holders of Senior and Subordinated Debt to the extent necessary to
pay the Debt in full, and we may be unable to meet fully our obligations with
respect to the Junior Subordinated Debt Securities.

    "Designated Senior and Subordinated Debt" is defined to mean

    - Debt under the Credit Agreement; and

    - Debt constituting Senior and Subordinated Debt which, at the time of its
      determination

    - has an aggregate principal amount of at least $30 million; and

    - is specifically designated in the instrument as "Designated Senior and
      Subordinated Debt" by us.

    "Senior and Subordinated Debt" is defined to mean the principal, premium, if
any, and interest on all of our Debt whether created, incurred or assumed
before, on or after the date of the Junior Subordinated Debt Indenture; provided
that Senior and Subordinated Debt shall not include

    - our Debt to any affiliate;

    - Debt of ours that, when incurred and without respect to any election under
      Section 1111(b) of Title 11, U.S. Code, was without recourse;

    - any other Debt of ours which by the terms of the instrument creating or
      evidencing the same are specifically designated as not being senior in
      right of payment to the Junior Subordinated Debt Securities, and in
      particular the Junior Subordinated Debt Securities shall rank equally with
      all other debt securities and guarantees issued to an AES Trust or any
      other trust, partnership or other entity affiliated with us which is a
      financing vehicle of ours in connection with an issuance of preferred
      securities by that financing entity and

    - our redeemable stock.

EVENTS OF DEFAULT

    An Event of Default, as defined in the Indentures and applicable to debt
securities issued thereunder, will occur with respect to the debt securities of
any series issued under the Indentures if:

    1.  we default in paying principal or premium, if any, on any debt security
        when due, upon acceleration, redemption, mandatory repurchase, or
        otherwise;

    2.  we default in paying interest on any debt security when it becomes due,
        and the default continues for a period of 30 days;

    3.  we default in performing or breach any other covenant or agreement in
        the Indentures and the default or breach continues for a period of 60
        consecutive days after written notice by the trustee or by the holders
        of 25% or more in aggregate principal amount of the debt securities of
        all series issued under an Indenture;

    4.  a court having jurisdiction enters a decree or order for

        - relief in respect of AES or any of our Material Subsidiaries in an
          involuntary case under any applicable bankruptcy, insolvency, or other
          similar law now or hereafter in effect;

        - appointment of a receiver, liquidator, assignee, custodian, trustee,
          sequestrator, or similar official of AES or any of our Material
          Subsidiaries or for all or substantially all of the property and
          assets of AES or any of our Material Subsidiaries or

        - the winding up or liquidation of the affairs of AES or any of our
          Material

                                       24

          Subsidiaries and, in each case, such decree or order shall remain
          unstayed and in effect for a period of 60 consecutive days;

    5.  AES or any of its Material Subsidiaries

        - commences a voluntary case under any applicable bankruptcy,
          insolvency, or other similar law now or hereafter in effect, or
          consents to the entry of an order for relief in an involuntary case
          under any such law,

        - consents to the appointment of or taking possession by a receiver,
          liquidator, assignee, custodian, trustee, sequestrator, or similar
          official of AES or any of its Material Subsidiaries or for all or
          substantially all of the property and assets of AES or any of its
          Material Subsidiaries or

        - effects any general assignment for the benefit of creditors; or

    6.  any other Events of Default set forth in the applicable prospectus
        supplement occur.

    If an Event of Default (other than an Event of Default specified in
clause (4) or (5) with respect to AES) occurs with respect to the debt
securities of any series and continues, then the trustee or the holders of at
least 25% in principal amount of the outstanding debt securities may, by written
notice to us, and the trustee at the request of at least 25% in principal amount
of the outstanding debt securities will, declare the principal, premium, if any,
and accrued interest on the outstanding debt securities to be immediately due
and payable. Upon a declaration of acceleration, the principal, premium, if any,
and accrued interest shall be immediately due and payable.

    If an Event of Default specified in clause (4) or (5) above occurs with
respect to AES, the principal, premium, if any, and accrued interest on the debt
securities shall be immediately due and payable, subject to the prior payment in
full of all Senior Debt, without any declaration or other act on the part of the
trustee or any holder. The holders of at least a majority in principal amount of
the outstanding debt securities may, by written notice to us and to the trustee,
waive all past defaults with respect to debt securities and rescind and annul a
declaration of acceleration with respect to debt securities of that series and
its consequences if:

    - all existing Events of Default applicable to debt securities of that
      series, other than the nonpayment of the principal, premium, if any, and
      interest on the debt securities that have become due solely by that
      declaration of acceleration, have been cured or waived and

    - the rescission would not conflict with any judgment or decree of a court
      of competent jurisdiction.

    For information as to the waiver of defaults, see "--Modification and
Waiver."

    The holders of at least a majority in principal amount of the outstanding
debt securities may direct the time, method, and place of conducting any
proceeding for any remedy available to the trustee or exercising any trust or
power conferred on the trustee. However, the trustee may refuse to follow any
direction that conflicts with law or the applicable Indenture, that may involve
the trustee in personal liability, or that the trustee determines in good faith
may be unduly prejudicial to the rights of holders of debt securities who did
not join in giving that direction and the trustee may take any other action it
deems proper that is not inconsistent with the direction received from holders
of outstanding debt securities. A holder may not pursue any remedy with respect
to the applicable Indenture or the debt securities of any series unless:

    - the holder gives the trustee written notice of a continuing Event of
      Default;

    - the holders of at least 25% in principal amount of outstanding debt
      securities make a written request to the trustee to pursue the remedy;

    - the holder or holders offer and, if requested, provide the trustee
      indemnity satisfactory to the trustee against any costs, liability or
      expense;

                                       25

    - the trustee does not comply with the request within 60 days after receipt
      of the request and the offer of indemnity and

    - with that 60-day period, the holders of at least a majority in principal
      amount of the outstanding debt securities do not give the trustee a
      direction that is inconsistent with the request.

    However, these limitations do not apply to the right of any holder of a debt
security to receive payment of the principal, premium, if any, or interest on,
that debt security or to bring suit for the enforcement of any payment, on or
after the due date expressed in the debt securities, which right shall not be
impaired or affected without the consent of the holder.

    Each of the Indentures requires that certain of our officers certify, on or
before a date not more than four months after the end of each fiscal year, that
to the best of those officers' knowledge, we have fulfilled all our obligations
under the Indenture. We are also obligated to notify the trustee of any default
or defaults in the performance of any covenants or agreements under any of the
Indentures.

    "Material Subsidiary" of a Person is defined to mean, as of any date, any
Subsidiary that would constitute a "significant subsidiary" within the meaning
of Article 1 of Regulation S-X of the Securities Act of 1933.

    "Subsidiary" means, with respect to any Person, any corporation, association
or other business entity of which a majority of the capital stock or other
ownership interests having ordinary voting power to elect a majority of the
board of directors or other persons performing similar functions are at the time
directly or indirectly owned by such Person.

    "Person" means an individual, a corporation, a partnership, a limited
liability company, an association, a trust or any other entity or organization,
including a government or political subdivision or an agency or instrumentality
thereof.

MODIFICATION AND WAIVER

    The Indentures may be amended or supplemented without the consent of any
holder of debt securities to:

    - cure ambiguities, defects, or inconsistencies;

    - comply with the terms in "Restriction on Mergers, Consolidations and Sales
      of Assets" described below;

    - comply with any requirements of the Securities and Exchange Commission in
      connection with the qualification of the Indentures under the Trust
      Indenture Act of 1939;

    - evidence and provide for the acceptance of appointment with respect to the
      debt securities by a successor Trustee;

    - establish the form or forms of debt securities of any series;

    - provide for uncertificated debt securities and to make all appropriate
      changes for such purpose; and

    - make any change that does not adversely affect the rights of any holder.

    Other modifications and amendments of the Indentures may be made with the
consent of the holders of not less than a majority in principal amount of the
outstanding debt securities of each series affected by the amendment (all such
series voting together as a single class). However, no modification or amendment
may, without the consent of each holder affected:

    - change the stated maturity of the principal of, or any sinking fund
      obligation or any installment of interest on, any debt security;

    - reduce the principal amount, premium, if any, or interest on, any debt
      security;

    - reduce the above-stated percentage of outstanding debt securities, the
      consent of whose holders is necessary to modify or

                                       26

      amend that Indenture with respect to the debt securities of any series
      issued under that Indenture;

    - reduce the percentage or principal amount of outstanding debt securities,
      the consent of whose holders is necessary for waiver of compliance with
      certain provisions of that Indenture or for waiver of certain defaults.

    A supplemental indenture which changes or eliminates any covenant or other
provision of an Indenture which has expressly been included solely for the
benefit of one or more particular series of debt securities issued under an
Indenture, or which modifies the rights of holders of debt securities of that
series with respect to that covenant or provision, shall be deemed not to affect
the rights under the applicable Indenture of the holders of debt securities of
any other series issued under the Indenture or of the coupons appertaining to
those debt securities. It is not necessary for the consent of the holders under
this section of an Indenture to approve the particular form of any proposed
amendment, supplement, or waiver, but it is sufficient if the consent approves
the substance thereof. After an amendment, supplement, or waiver under this
section of an Indenture becomes effective, we will give to the holders affected
thereby a notice briefly describing the amendment, supplement, or waiver. We
will mail supplemental indentures to holders upon request. Any failure of us to
mail a notice, or any defect therein, will not affect the validity of any
supplemental indenture or waiver.

RESTRICTION ON MERGERS, CONSOLIDATIONS AND SALES OF ASSETS

    Pursuant to the Indentures, we may not consolidate with, merge with or into,
or transfer all or substantially all of our assets to any Person unless:

    - AES shall be the continuing Person, or, if AES is not the continuing
      Person, the Person formed by such consolidation or into which we merged or
      to which properties and assets of ours are transferred is a solvent
      corporation organized and existing under the laws of the United States or
      any State thereof or the District of Columbia and expressly assumes in
      writing all the obligations of ours under the Notes,

    - immediately after giving effect to such transaction no Event of Default
      has occurred and is continuing and

    - other conditions as may be established in connection with the issuance of
      the applicable Debt Securities are met.

DEFEASANCE AND DISCHARGE

    The Indentures provide that we are deemed to have paid and will be
discharged from all obligations in respect of the debt securities of any series
on the 123rd day after the deposit referred to below has been made, and that the
provisions of an Indenture will no longer be in effect with respect to the debt
securities issued thereunder (except for, among other matters, certain
obligations to register the transfer or exchange of the Debt Securities of such
series, to replace stolen, lost or mutilated Debt Securities of such series, to
maintain paying agencies and to hold monies for payment in trust) if, among
other things,

    - we have deposited with the trustee, in trust, money and/or U.S. Government
      Obligations that through the payment of interest and principal in respect
      thereof, will provide money in an amount sufficient to pay the principal,
      premium, if any, and accrued interest on the applicable debt securities,
      on the due date thereof or earlier redemption (irrevocably provided for
      under arrangements satisfactory to the trustee), as the case may be, in
      accordance with the terms of the Indenture and the applicable debt
      securities,

    - we have delivered to the trustee

      - either

            -- an opinion of counsel to the effect that holders will not
               recognize income, gain or loss for federal income tax purposes as
               a result of the exercise of

                                       27

               our option under this "Defeasance" provision and will be subject
               to federal income tax on the same amount and in the same manner
               and at the same times as would have been the case if the deposit,
               defeasance and discharge had not occurred, which opinion of
               counsel must be based upon a ruling of the Internal Revenue
               Service to the same effect unless there has been a change in
               applicable federal income tax law or related treasury regulations
               after the date of the Indenture that a ruling is no longer
               required or

            -- a ruling directed to the trustee received from the Internal
               Revenue Service to the same effect as the aforementioned opinion
               of counsel and

    - an opinion of counsel to the effect that the creation of the defeasance
      trust does not violate the Investment Company Act of 1940 and after the
      passage of 123 days following the deposit, the trust fund will not be
      subject to the effect of Section 547 of the U.S. Bankruptcy Code or
      Section 15 of the New York Debtor and Creditor Law,

    - immediately after giving effect to that deposit on a pro forma basis, no
      Event of Default has occurred and is continuing on the date of the deposit
      or during the period ending on the 123rd day after the date of the
      deposit, and the deposit will not result in a breach or violation of, or
      constitute a default under, any other agreement or instrument to which we
      are a party or by which we are bound,

    - we are not prohibited from making payments in respect of the applicable
      debt securities by the subordination provisions contained in an Indenture
      and

    - if at that time the applicable debt securities are listed on a national
      securities exchange, we have delivered to the trustee an opinion of
      counsel to the effect that the debt securities will not be delisted as a
      result of a deposit, defeasance and discharge.

    As more fully described in the prospectus supplement, the Indentures also
provide for defeasance of certain covenants.

        DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

    We may issue Stock Purchase Contracts, which represent contracts obligating
holders to purchase from us a specified number of shares of common stock at a
future date or dates. The price per share of common stock may be fixed at the
time the stock purchase contracts are issued or may be determined by reference
to a specific formula described in the stock purchase contracts. The stock
purchase contracts may be issued separately or as a part of units ("Stock
Purchase Units") consisting of a stock purchase contract and debt securities or
debt obligations of third parties, including U.S. Treasury securities, securing
the holders' obligations to purchase the common stock under the stock purchase
contracts. The stock purchase contracts may require us to make periodic payments
to the holders of the stock purchase units or vice versa, and these payments may
be unsecured or prefunded on some basis. The stock purchase contracts may
require holders to secure their obligations thereunder in a specified manner.

    The prospectus supplement will describe the terms of any stock purchase
contracts or stock purchase units. The description in the prospectus supplement
will not be complete and will be qualified by reference to the stock purchase
contracts, and, if applicable, additional arrangements, relating to the stock
purchase contracts or stock purchase units.

                                       28

                       DESCRIPTION OF SECURITIES WARRANTS

    We may issue securities warrants for the purchase of debt securities,
preferred stock or common stock. Securities warrants may be issued independently
or together with debt securities, preferred stock or common stock and may be
attached to or separate from any offered securities. Each series of securities
warrants will be issued under a separate warrant agreement to be entered into
between us and a bank or trust company, as warrant agent. The securities warrant
agent will act solely as our agent in connection with the securities warrants
and will not assume any obligation or relationship of agency or trust for or
with any registered holders of securities warrants or beneficial owners of
securities warrants. This summary of some provisions of the securities warrants
is not complete. You should refer to the securities warrant agreement, including
the forms of securities warrant certificate presenting the securities warrants,
relating to the specific securities warrants being offered for the complete
terms of the securities warrant agreement and the securities warrants. That
securities warrant agreement, together with the terms of securities warrant
certificate and securities warrants, will be filed with the Securities and
Exchange Commission in connection with the offering of the specific securities
warrants.

    The particular terms of any issue of securities warrants will be described
in the prospectus supplement relating to the issue. Those terms may include:

    - the designation, aggregate principal amount, currencies, denominations and
      terms of the series of debt securities purchasable upon exercise of
      securities warrants to purchase debt securities and the price at which the
      debt securities may be purchased upon exercise;

    - the designation, number of shares, stated value and terms (including,
      without limitation, liquidation, dividend, conversion and voting rights)
      of the series of preferred stock purchasable upon exercise of securities
      warrants to purchase shares of preferred stock and the price at which such
      number of shares of preferred stock of such series may be purchased upon
      such exercise;

    - the number of shares of common stock purchasable upon the exercise of
      securities warrants to purchase shares of common stock and the price at
      which such number of shares of common stock may be purchased upon such
      exercise;

    - the date on which the right to exercise the securities warrants will
      commence and the date on which the right will expire;

    - United States Federal income tax consequences applicable to the securities
      warrants; and

    - any other terms of the securities warrants.

    Securities warrants for the purchase of preferred stock and common stock
will be offered and exercisable for U.S. dollars only. Securities warrants will
be issued in registered form only. The exercise price for securities warrants
will be subject to adjustment in accordance with the applicable prospectus
supplement.

    Each securities warrant will entitle its holder to purchase the principal
amount of debt securities or the number of shares of preferred stock or common
stock at the exercise price set forth in, or calculable as set forth in, the
applicable prospectus supplement. The exercise price may be adjusted upon the
occurrence of certain events as set forth in the prospectus supplement. After
the close of business on the expiration date, unexercised securities warrants
will become void. We will specify the place or places where, and the manner in
which, securities warrants may be exercised in the applicable prospectus
supplement.

    Prior to the exercise of any securities warrants to purchase debt
securities, preferred stock or common stock, holders of the securities warrants
will not have any of the rights of holders of the debt securities, preferred
stock or

                                       29

common stock purchasable upon exercise, including:

    - in the case of securities warrants for the purchase of debt securities,
      the right to receive payments of principal of, any premium or interest on
      the debt securities purchasable upon exercise or to enforce covenants in
      the applicable indenture; or

    - in the case of securities warrants for the purchase of preferred stock or
      common stock, the right to vote or to receive any payments of dividends on
      the preferred stock or common stock purchasable upon exercise.

                              PLAN OF DISTRIBUTION

    We may sell the securities in any of three ways (or in any combination
thereof):

    - through underwriters or dealers;

    - directly to a limited number of purchasers or to a single purchaser; or

    - through agents.

    The prospectus supplement will set forth the terms of the offering of such
securities, including

    - the name or names of any underwriters, dealers or agents and the
      respective amounts of securities underwritten or purchased by each of
      them,

    - the initial public offering price of the securities and the proceeds to us
      and any discounts, commissions or other items constituting compensation
      from us and any discounts, commissions or concessions allowed or reallowed
      or paid to dealers and any securities exchanges on which the securities
      may be listed.

    Any initial 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 securities, the 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. The securities may be either offered to the public through underwriting
syndicates represented by managing underwriters, or directly by underwriters.
Unless otherwise described in the prospectus supplement, the obligations of the
underwriters to purchase the securities will be subject to certain conditions
and the underwriters will be obligated to purchase all of the securities if any
are purchased.

    If a dealer is utilized in the sale of any offered securities, we will sell
those securities to the dealer, as principal. The dealer may then resell the
offered securities to the public at varying prices to be determined by the
dealer at the time of resale.

    Offered Securities may be sold directly by us or through agents designated
by us 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 us 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.

    We may authorize underwriters, dealers or agents to solicit offers by
certain purchasers to purchase the securities from us 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.
These 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 to indemnification by us against
certain civil liabilities, including liabilities under the

                                       30

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 us in
the ordinary course of business.
